DETAILED DESCRIPTION OF THE EMBODIMENTS
[0038] It should be noted that if there is a directional indication (such as up, down, left, right, front, rear...) in the embodiments of the present disclosure, the directional indication is only used to explain the relative positional relationship, movement, etc. of the components in a certain posture (as shown in the drawings). If the specific posture changes, the directional indication will change accordingly.
[0039] In addition, the descriptions associated with, e.g., "first" and "second," in the present disclosure are merely for descriptive purposes, and cannot be understood as indicating or suggesting relative importance or impliedly indicating the number of the indicated technical feature. Therefore, the feature associated with "first" or "second" can expressly or impliedly include at least one such feature. Besides, the technical solutions between the various embodiments can be combined with each other, but they must be based on the realization of those of ordinary skill in the art. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that such a combination of technical solutions does not exist, nor is it within the scope of the present disclosure.
[0040] In some embedded electrical appliances with revolving doors, decorative hanging boards are usually installed on the revolving doors, so that the overall style of the electrical appliance is more compatible with the surrounding environment. However, this may cause the decorative hanging board to interfere with the ground or other structures below when the revolving door is opened. In order to avoid such interference, the decorative hanging board may slide relative to the revolving door, so that during the opening process of the revolving door, the decorative hanging plate slides upward to avoid the lower end of the decorative hanging board from colliding with the ground or other structures. However, this usually needs to be equipped with a complex transmission structure such as multi-stage gears, which is difficult to process, high in production cost, easily stuck by foreign objects, and has low reliability.
[0041] In order to solve the above technical problem, the present disclosure provides a hinge 500, during the rotation and opening process of the door body 200 (equivalent to a revolving door), the hinge 500 can realize that the outer panel 300 (equivalent to the decorative hanging board) moves upward (upward, that is, toward the top of the door body), for example, slides upward, or translates upward, and during the rotation and closing process of the door body 200, the panel 300 is reset accordingly. The hinge 500 can be applied to furniture, and can also be applied to the built-in electrical device, such as built-in dishwashers, built-in ovens, and the like.
[0042] The present disclosure also provides an electrical device including the hinge 500. In an embodiment, the electrical device is a dishwasher, the dishwasher has an inner cavity for loading tableware, a basket is provided in the inner cavity, and the tableware is loaded in the basket. In the following embodiments, a dishwasher is taken as an example to describe the structure of the electrical device and the hinge 500 in detail.
[0043] The built-in dishwasher is usually embedded in the cabinet, and a decorative hanging board covering the front of the dishwasher is installed on the outside of the revolving door. The material or design style of the decorative hanging board is usually the same as the door panel of the cabinet, so that the dishwasher and the cabinet form a beautiful whole in appearance and play a decorative role. The size of the decorative hanging board can be designed according to the shape of the adjacent cabinets to meet the needs of users. In some occasions, the length of the decorative hanging board needs to be designed to be longer to cover the dishwasher more completely, such that the outer side of the dishwasher and the adjacent cabinet door panel are more unified and beautiful, but this may cause the lower end of the decorative hanging board to interfere with the cabinet body or the ground when the revolving door of the dishwasher is opened, causing inconvenience to the user.
[0044] In an embodiment of the present disclosure, as shown in FIG. 1 to FIG. 3, the electrical device includes a main body 100, a door body 200, and the hinge 500 connecting the main body 100 and the door body 200. The main body 100 may be a main body of an electrical device, such as a body of a built-in dishwasher, the main body 100 has an inner cavity, the inner cavity has an opening, and the door body 200 is openably and closably provided at the opening. In this embodiment, as shown in FIG. 6 to FIG. 11, the door body 200 is rotatably connected to the main body 100 through the hinge 500. The door body 200 rotates around a first direction. The extension direction of the first direction is the direction in which the rotating shaft 203 extends. Generally speaking, the first direction is a direction parallel to the placement surface of the main body 100, e.g., parallel to the ground. The door body 200 has a closed state in which the main body 100 is rotated to close (in some embodiments, the opening is closed), and an open state in which the main body 100 is rotated to open (in some embodiments, the opening is opened). The door body 200 has a fixed end 201 and a rotating end 202 arranged along a second direction, and the second direction may intersect the first direction. Here, the fixed end 201 and the rotating end 202 are relatively speaking, the one close to the hinge 500 is the fixed end 201, and the one far from the hinge 500 is the rotating end. For example, when the electrical device is placed on the ground, the bottom end of the door body 200 is the fixed end 201, and the top end of the door body 200 is the rotating end 202. The fixed end 201 is rotatably connected to the main body 100 by the rotating shaft 203 extending around the first direction. The rotating end 202 rotates relative to the fixed end 201 to switch the door body 200 between the open state and the closed state. As shown in FIG. 6 to FIG. 11, during the process of switching the door body 200 from the closed state to the open state, the rotating end 202 has a movement stroke that rotates around the fixed end 201 and rotates away from the main body 100. On the contrary, during the process of switching the door body 200 from the open state to the closed state, the rotating end 202 has a movement stroke that rotates around the fixed end 201 and is close to the main body 100.
[0045] In this embodiment, the first direction is the extension direction of the rotating shaft 203, the second direction is the direction in which the panel 300 moves relative to the door body 200, and the second direction may be substantially parallel to the plane where the outside of the door body 200 is located. In some embodiments, the first direction and the second direction intersect, the first direction is substantially perpendicular to the second direction, and the actual directions of the first direction and the second direction are not limited. In an embodiment, the first direction may extend substantially in a horizontal direction, and the second direction is substantially parallel to the outer surface of the door body 200 and substantially perpendicular to the first direction. A dishwasher is taken as an example, the first direction is substantially along the horizontal direction, the second direction is parallel to the outer surface of the door body 200 and substantially perpendicular to the first direction, and the second direction extends vertically when the door body 200 is in a closed state. In this way, the door body 200 can be flipped open from top to bottom relative to the main body 100, the panel 300 moves relative to the outside of the door body 200 toward the rotating end 202, that is, the direction away from the hinge 500 moves relative to the door body 200 to avoid interference and collision between the lower end of the panel 300 and the ground or other structures.
[0046] It should be noted that the description of the orientation in the present disclosure is only applicable to the orientation description of the electrical device in the normal use state after the installation is completed, and does not include the orientation of the electrical device in the state of production, assembly or transportation. The horizontal direction refers to a direction substantially parallel to the horizontal plane, and the up-down direction refers to a direction substantially parallel to the direction of gravity, or a direction that forms a certain angle with the direction of gravity and is not perpendicular to each other.
[0047] The electrical device further includes a panel 300, and the panel 300 is movably provided on one side of the door body 200. In some embodiments, the panel 300 may be movably provided on one side of the door body 200 along the second direction. When the door body 200 is rotated, the panel 300 can move relative to the door body 200 (e.g., slide relative to the door body 200 substantially parallel to the door body 200). For those skilled in the art, when the door is opened, that is, when the rotating end 202 rotates away from the main body 100, the panel 300 moves relative to the door body 200 along the second direction and away from the fixed end 201. The panel 300 may be a decorative hanging board, or may be other plate-like structures that can move relative to the door body 200. In this embodiment, since the panel 300 moves from the fixed end 201 to the rotating end 202 as the door body 200 rotates, it is possible to avoid interference and collision between one end of the panel 300 close to the fixed end 201 and surrounding structures, such as the cabinet, the ground, and the like. When the door body 200 is changed from the open state to the closed state, the panel 300 can be reset in the opposite direction (the direction from the rotating end 202 to the fixed end 201).
[0048] In order to realize the above-mentioned transmission, in this embodiment, as shown in FIG. 1 to FIG. 3, the present disclosure further provides a hinge 500, the hinge 500 is used to connect the door body 200 and the main body 100, so that the door body 200 can be rotatably arranged relative to the main body 100 around the rotating shaft 203 extending in the first direction. One side of the door body 200 is provided with a movable panel 300, the door body 200 has a fixed end 201 and a rotating end 202 arranged in the second direction. When the door body 200 is switched from the closed state to the open state, the rotating end 202 rotates around the fixed end 201 and rotates away from the main body 100. When the door body 200 is switched from the open state to the closed state, the rotating end 202 rotates around the fixed end 201 and rotates close to the main body 100.
[0049] As shown in FIG. 3, the panel 300 is provided on one side of the door body 200, including but not limited to the side of the door body 200 facing away from the main body 100. During the process of the door body 200 being rotated and opened, the rotating end 202 rotates away from the main body 100, while the panel 300 moves relative to the door body 200 along the second direction and away from the fixed end 201. In this way, the panel 300 moves from the fixed end 201 to the direction of the rotating end 202 as the door body 200 is rotated and opened, it is possible to avoid interference and collision between one end of the panel 300 close to the fixed end 201 and surrounding structures, such as the cabinet, the ground, and the like. On the contrary, during the process of rotating and closing the door body 200, the rotating end 202 rotates close to the main body 100, and the panel 300 moves relative to the door body 200 along the second direction and in a direction close to the fixed end 201 (i.e., the opposite direction) (equivalent to the panel 300 being reset). In this way, the panel 300 moves from the rotating end 202 to the fixed end 201 as the door body 200 rotates and closes. In this way, when the door body 200 is in a closed state, the position of the panel 300 is adapted to the surrounding cabinet body of the electrical device, and the appearance is more uniform and beautiful.
[0050] Further, the hinge 500 includes a rotating shaft 203, a hinge arm 10, a drive arm 20 and a mounting member 30. In this embodiment, the specific shapes and sizes of the rotating shaft 203, the hinge arm 10, the drive arm 20 and the mounting member 30 are not limited. For example, the hinge arm 10, the drive arm 20 and the mounting member 30 may be in the shape of a plate, a rod or the like. In some embodiments, the hinge arm 10 is used to rotatably connect the main body 100 and the door body 200, as shown in FIG. 6 to FIG. 11, the hinge arm 10 has a first connection portion 11 for rotatably connecting around the rotating shaft 203, the rotating shaft 203 extending along the first direction. The position of the rotating shaft 203 may not be limited, as long as the hinge arm 10 can be rotated relative to the main body 100. For example, the rotating shaft 203 is fixed on the mounting member 30, the mounting member 30 is provided on the main body 100, and the hinge arm 10 is rotatably provided on the rotating shaft 203. That is, the rotating shaft 203 connects the mounting member 30 and the hinge arm 10 (the rotating shaft 203 is fixed on the mounting member 30, and the hinge arm 10 is rotatably connected to the rotating shaft 203, or the rotating shaft 203 is fixed on the hinge arm 10, and the rotating shaft 203 is rotatably connected to the mounting member 30). Further, the drive arm 20 can be provided between the hinge arm 10 and the mounting member 30 to simplify the structure. The hinge arm 10 further has a first arm 12 and a second arm 13 around the rotating shaft 203. The first arm 12 is used for connecting with the door body 200, such as connecting to the fixed end 201, the second arm 13 is used for connecting with the main body 100. Generally speaking, the second arm 13 is elastically connected to the main body 100, that is, elastically connected to the main body 100 through a pull cord and a tension spring. The hinge 500 can realize the rotational connection between the main body 100 and the door body 200, such that the rotating end 202 rotates around the fixed end 201 toward or away from the main body 100, and the door body 200 is switched between the closed state and the open state.
[0051] The drive arm 20 is rotatably connected with the panel 300, and the rotational connection here is relative. For example, when the door body 200 is opened or closed, the drive arm 20 and the panel 300 can rotate relative to each other. The drive arm 20 may be stationary while the panel 300 is rotated, or both the drive arm 20 and the panel 300 may be rotated, as long as either one can rotate relative to the other, it can be regarded as a rotational connection. As shown in FIG. 1, FIG. 2, and FIG. 12 to FIG. 19, a second guide mechanism is provided between the drive arm 20 and the hinge arm 10, a first guide mechanism is provided between the mounting member 30 and the drive arm 20, the first guide mechanism and the second guide mechanism guide the drive arm 20 to drive the panel 300 to move relative to the door body 200 when the door body 200 is rotated. It can be understood that the rotation of the door body 200 includes the opening of the door body 200 and the closing of the door body 200. When the door body 200 rotates, the drive arm 20 rotates relative to the panel 300, and the drive arm 20 rotates relative to the panel 300 as described above, which are relative. As long as any one can rotate relative to the other, it can be regarded as a rotational connection, and details are not repeated here. When the door body 200 is opened, because the hinge arm 10 and the drive arm 20 are directly or indirectly connected with the door body 200, the door body 200 can drive the movement of the hinge arm 10 and the drive arm 20. A first guide mechanism is provided between the mounting member 30 and the drive arm 20, and a second guide mechanism is provided between the drive arm 20 and the hinge arm 10, the first guide mechanism and the second guide mechanism jointly constrain the drive arm 20, thereby urging the drive arm 20 to rotate relative to the panel 300 and driving the panel 300 to move relative to the door body 200.
[0052] When the door body 200 rotates, the drive arm 20 moves along with the rotation of the hinge arm 10, and the first guide mechanism restricts the drive arm 20 from rotating following the rotation of the hinge arm 10. For example, during the opening stroke, when the hinge arm 10 rotates, it can drive the drive arm 20 to approach the door body 200, restricting the rotation of the drive arm 20 following the rotation of the hinge arm 10 can be understood as the fact that the movement ranges of the drive arm 20 and the hinge arm 10 are inconsistent. For example, the drive arm 20 and the hinge arm 10 can rotate relative to each other. It may be that the drive arm 20 does not rotate while the hinge arm 10 rotates, or the rotation range of the drive arm 20 is smaller than the rotation range of the hinge arm 10. It can also be that the rotation direction of the drive arm 20 is different from the rotation direction of the hinge arm 10 (the drive arm 20 rotates reversely relative to the hinge arm 10), or the drive arm 20 is restricted to reciprocate in a straight line while the hinge arm 10 rotates. It is equivalent to applying a constraint to the drive arm 20 when the hinge arm 10 rotates, so that when the hinge arm 10 moves along with the rotation of the hinge arm 10, it cooperates with the second guide mechanism, when the door body is opened, the panel 300 is urged to move relative to the door body 200 in the direction away from the hinge 500, and when the door body 200 is closed, the panel 300 is urged to move relative to the door body 200 in the direction of the hinge 500.
[0053] When the door body 200 rotates, the second guide mechanism makes the drive arm 20 move following the rotation of the hinge arm 10. For example, when the door body is opened, the hinge arm 10 rotates, and the drive arm 20 can follow the hinge arm 10 to move toward the door body 200. At this time, in cooperation with the first guide mechanism, the drive arm 20 moves in a direction close to the door body 200 to act on the panel 300. For example, when the door body 200 is opened, the first guide mechanism restricts the rotation of the drive arm 20, and due to the driving effect of the second guide mechanism, the drive arm 20 moves toward the door body 200 as a whole, so as to promote the drive arm 20 to move in the direction away from the hinge, at this time, the panel 300 is rotated relative to the drive arm 20. In this way, the movement of the panel 300 can be effectively linked with the rotation of the door body 200 through the second guide mechanism.
[0054] Compared with the technical solution in the prior art in which the panel 300 moves with the opening or closing of the door body 200 by using structures such as multi-stage gear transmission, the technical solution provided in this embodiment can be achieved through the restraint between the hinge arm 10, the drive arm 20 and the mounting member 30 in the hinge 500, the linkage between the rotation of the door body 200 and the movement of the panel 300 can be realized, the structure is simple and reliable, and the structure of the hinge 500 is easy to manufacture, the production cost is low, the transmission is simple, the jamming phenomenon is not easy to occur, and the reliability is high. In the embodiments above, no multi-stage gear transmission is needed.
[0055] As shown in FIG. 1 and FIG. 12 to FIG. 19, the drive arm 20 has a first drive end 21 and a second drive end 22. The first guide mechanism is provided between the first drive end 21 and the mounting member 30, and the second drive end 22 is rotatably connected with the panel 300. That is, the movement of the first drive end 21 of the drive arm 20 is restricted by the first guide mechanism. It can be understood that, since the panel 300 has a relative movement relative to the door body 200 (for example, along the second direction), during the movement of the door body 200 being rotated and opened, the movement of the hinge arm 10 causes the drive arm 20 to be forced to change its position. The first guide mechanism constrains the hinge arm 10, so that the movement trajectory of the drive arm 20 can be limited. In some embodiments, during the opening stroke, the first guide mechanism limits the movement trajectory of the first drive end 21 relative to the main body 100 to be gradually disposed closer to the door body 200, such that the second drive end 22 of the drive arm 20 drives the panel 300 to move in the second direction away from the fixed end 201 along with the rotation of the hinge arm 10.
[0056] The specific structures of the first guide mechanism and the second guide mechanism are not limited in this embodiment, for example, they can be sliding pins and sliding grooves that cooperate with each other, as long as the restraint on the drive arm 20 can be achieved, the drive arm 20 can be driven to move, such that during the movement of the rotating end 202 away from the main body 100, through the arrangement of the first guide mechanism and the second guide mechanism, the movement trajectory of the first drive end 21 gradually approaches the door body 200. During the rotation and opening of the hinge arm 10, the drive arm 20 can drive the second drive end 22 to drive the panel 300 to move relative to the door body 200 along the second direction and away from the fixed end 201. On the contrary, during the process of closing the door body 200, the rotating end 202 rotates to be close to the main body 100, through the first guide mechanism and the second guide mechanism, during the process of rotating and closing the hinge arm 10, the drive arm 20 can drive the second drive end 22 to drive the panel 300 to move relative to the door body 200 along the second direction and in a direction close to the fixed end 201, and the movement trajectory of the first drive end 21 is gradually away from the direction of the door body 200.
[0057] It can be understood that the first guide mechanism may be provided between the drive arm 20 and the main body 100. For example, the sliding pin or the sliding groove is directly formed on the main body 100, and the sliding groove or the sliding pin is correspondingly provided on the drive arm 20. With this arrangement, the hinge 500 has fewer components and occupies a smaller space, which is beneficial to maximizing the size of the electrical device.
[0058] In this embodiment, as shown in FIG. 1 and FIG. 12 to FIG. 19, the first guide mechanism is provided with the sliding pin or the sliding groove through the mounting member 30 provided separately from the main body 100. The mounting member 30 can be connected to the main body 100 by means of bolts, welding or the like. Compared with the technical solution of directly processing the main body 100 in this embodiment, a separate mounting member 30 is configured to cooperate with the drive arm 20, and the first guide mechanism is provided between the mounting member 30 and the drive arm 20, so that the hinge 500 is easier to manufacture and has a low production cost. In addition, the structure of the existing electrical device can be used, and there is no need to re-open the mold, which reduces the cost of research and development, and is also beneficial to the application of different materials for the hinge 500 and the main body 100.
[0059] As shown in FIG. 1 and FIG. 12 to FIG. 19, the mounting member 30 may be fixed to the main body 100 by means of bolts or other structural connections. The first guide mechanism includes a first guide pin 41 and a first guide groove 42 respectively disposed on the drive arm 20 and the mounting member 30. In some embodiments, the first guide pin 41 may be provided on the first drive end 21 of the drive arm 20, the first guide groove 42 is provided on the mounting member 30, and the first guide pin 41 may also be provided on the mounting member 30. The first guide groove 42 is provided on the first drive end 21 of the drive arm 20 as long as the cooperation between the first drive end 21 and the mounting member 30 can be achieved. The first guide pin 41 matches with the first guide groove 42 (inserted in each other), such that when the rotating end 202 is away from the main body 100, the movement trajectory of the second drive end 22 gradually approaches the direction of the door body 200. On the contrary, when the rotating end 202 is close to the main body 100, the movement trajectory of the second drive end 22 gradually moves away from the door body 200.
[0060] Through the above structural arrangement, during the process of rotating and opening the door body 200, when the first drive end 21 of the drive arm 20 is pulled to move in a direction close to the door body 200, the rotation is also restricted by the cooperation of the first guide pin 41 and the first guide groove 42, thus, the second drive end 22 of the drive arm 20 is driven to drive the panel 300 to move in the direction of the door body 200 toward the rotated end 202. On the contrary, when the door body 200 is rotated and closed, when the first drive end 21 of the drive arm 20 is pulled to move in the direction close to the main body 100, the rotation is also restricted by the cooperation of the first guide pin 41 and the first guide groove 42, thus, the second drive end 22 of the drive arm 20 is driven to drive the panel 300 to move in the direction of the door body 200 toward the fixed end 201. In this embodiment, the linkage between the opening or closing of the door body 200 and the movement of the panel 300 along the door body 200 can be realized through the arrangement of the first guide pins 41 and the first guide grooves 42. The structure is simple and reliable. Compared with complex transmission structures such as multi-stage gears, it is not easy to be stuck, easy to manufacture, and low in production cost.
[0061] In this embodiment, as shown in FIG. 1 and FIG. 12 to FIG. 19, the first guide pin 41 is provided on the first drive end 21, the first guide groove 42 is provided on the mounting member 30, and the first guide groove 42 is bent from the main body 100 toward the door body 200. The specific shape of the first guide groove 42 can be various, for example, it can be a straight line or an arc shape, or a combination of a straight line and an arc shape, as long as the drive arm 20 can be restricted. When the hinge arm 10 is opened or closed, the second drive end 22 of the drive arm 20 may drive the panel 300 to move in the direction of the fixed end 201 or the rotating end 202 along the door body 200.
[0062] As described above, the first guide groove 42 can be linear (the whole is linear without obvious bending). When the first guide groove 42 is linear, the first guide groove 42 may extend laterally or be inclined from the main body 100 toward the door body 200. Compared with the straight shape, the curved first guide groove 42 may have lower resistance to a certain extent, and the movement of the panel 200 may be non-uniform according to the design. For example, in this embodiment, the first guide groove 42 extends in an arc shape, so as to make the sliding of the first guide pin 41 smoother and avoid the occurrence of jamming.
[0063] In this embodiment, through the arrangement of the first guide groove 42 on the mounting member 30, the first drive end 21 of the drive arm 20 is constrained by the first guide groove 42 on the mounting member 30, the second drive end 22 of the drive arm 20 moves relative to the hinge arm 10 along the second direction. In this way, during the outward rotation of the hinge arm 10 extending along the first direction of the rotating shaft 203 (the opening stroke), the drive arm 20 is driven to drive the panel 300 to move away from the fixed end 201 along the second direction. On the contrary, during the inward rotation of the hinge arm 10 along the rotating shaft 203 extending in the first direction (the closing stroke), the drive arm 20 is driven to drive the panel 300 to move in the second direction and close to the fixed end 210. In this embodiment, the linkage between the opening of the door body 200 and the movement of the panel 300 along the door body 200 can be realized by the arrangement of the first guide pin 41 and the first guide groove 42. The structure is simple and reliable. Compared with complex transmission structures such as multi-stage gears, it is not easy to be stuck, easy to manufacture, and low in production cost.
[0064] Further, as shown in FIG. 3 and FIG. 5, in some cases, the door body 200 may be blocked near the rotating end 202. A built-in dishwasher installed in a cabinet is taken as an example, the top plate 400 on the upper side of the cabinet may interfere with the upper end of the panel 300. When the door body 200 is rotated and opened, the panel 300 starts to move upward relative to the door body 200 prematurely, which is likely to cause the upper end of the panel 300 to collide with the top plate 400, which affects the user's use. In this case, it is necessary to design the panel 300 not to move upward or to a lesser extent during the initial stroke of the door body 200 when the door body 200 is rotated and opened, so as to avoid the collision between the upper end of the panel 300 and the top plate 400, the door body 200 is moved to the top of the door body 200 in the latter part of the stroke when the door body 200 is opened, so as to prevent the lower end of the panel 300 from colliding with the ground. That is to say, during the entire stroke of the door body 200 being rotated and opened, the moving speed of the panel 300 is not uniform, which needs to be designed according to the actual situation. It can be understood that, in other cases, during the opening process of the door body 200, the travel of the panel 300 relative to the door body 200 may be adaptively designed according to actual requirements. In the traditional complex transmission structure, this kind of adaptive design requires technical personnel to carry out precise design and pay higher research and development costs. In the embodiments of the present disclosure, the design requirement of the movement stroke of the panel 300 relative to the door body 200 can be met simply by adapting the shape of the first guide groove 42, not only can a variety of stroke designs be realized, but also easy to realize, with low R&D cost and high reliability.
[0065] In an embodiment, as shown in FIG. 3 and FIG. 5, the dishwasher is taken as an example in the electrical device, in order to avoid mutual interference between the upper end of the panel 300 and the top plate 400, it can be designed during the previous stroke of the door body 200 being rotated and opened, the position of the panel 300 relative to the door body 200 remains unchanged. In this way, the collision between the upper end of the panel 300 and the top plate 400 is avoided, and during the rearward stroke of the door body 200 being rotated and opened, the panel 300 moves relative to the door body 200 along the second direction and away from the fixed end 201, so as to prevent the lower end of the panel 300 from colliding with the ground. It can be understood that, in the embodiment, the previous stroke and the rearward stroke refer to two stages arranged according to time in the rotation and opening stroke of the door body 200. The previous stroke and the rearward stroke may be arranged next to each other, or may be arranged at intervals. Similarly, in the previous stroke of the door body 200 being rotated and closed, the panel 300 moves relative to the door body 200 along the second direction and is close to the fixed end 201 to prevent the lower end of the panel 300 from colliding with the ground. During the rearward stroke of the door body 200 being rotated and closed, the position of the panel 300 relative to the door body 200 remains unchanged, so as to prevent the upper end of the panel 300 from colliding with the top plate 400.
[0066] As shown in FIG. 2, the first guide groove 42 has a first section 421 and a second section 422 arranged in sequence, the first section 421 is in an arc shape, and the arc shape means that the first section 421 is in an arc shape with a substantially constant radius. In this way, in the previous stroke of the door body 200 being opened, the first guide pin 41 slides in the first section 421, that is, the drive arm 20 is not restricted by the first guide mechanism (not restricted to rotate following the rotation of the hinge arm 10), the first drive end 21 of the drive arm 20 rotates relative to the rotating shaft 203, the second drive end 22 does not move or moves relatively small relative to the hinge arm 10, so as not to drive the panel 300 to move relative to the door body 200. That is to say, the panel 300 is fixed relative to the door body 200 during the previous stroke of the rotation of the rotating end 202 away from the main body 100. During the rearward stroke of the door body 200 being opened, the rotating end 202 continues to rotate away from the main body 100. Since the second section 422 is in an arc shape with a gradually decreasing radius, when the drive arm 20 moves along with the rotation of the hinge arm 10, it will be restricted by the rotation (the rotation restriction is as described above, it can be understood that the movement range of the drive arm 20 and the hinge arm 10 are inconsistent. For example, relative rotation between the drive arm 20 and the hinge arm 10 can occur. It can be that the drive arm 20 does not rotate while the hinge arm 10 rotates. It can also be that the rotation range of the drive arm 20 around the first guide pin 41 is smaller than the rotation range of the hinge arm 10. It can also be that the rotation direction of the drive arm 20 around the first guide pin 41 is different from the rotation direction of the hinge arm 10 (i.e. rotate in the opposite direction). Therefore, the second drive end 22 drives the panel 300 to move relative to the door body 200 along the second direction and away from the fixed end 201. It can be understood that, through the structural design of the hinge 500, during the closing stroke of the door body 200, the panel 300 has an opposite movement stroke, which is not repeated herein.
[0067] Through the above structure, the position of the panel 300 relative to the door body 200 remains unchanged in the previous stage of the door body 200 being rotated and opened. In the rearward stage when the door body 200 is rotated and opened, the panel 300 moves relative to the door body 200 along the second direction and away from the fixed end 201, so as to avoid collision between the panel 300 and the top panel 400. On the contrary, in the previous stage of the rotation and closing of the door body 200, the panel 300 moves relative to the door body 200 in the second direction and in the direction close to the fixed end 201. In the rearward stage of the rotation and closing of the door body 200, the position of the panel 300 relative to the door body 200 remains unchanged, so as to prevent the panel 300 from colliding with the top panel 400. As such, in this embodiment, through the simple structural design of the first guide groove 42, the movement stroke control of the panel 300 during the rotation process of the door body 200 is realized. The structure is simple and easy to realize. Furthermore, the moving speed of the panel 300 is precisely controlled according to the actual situation of the electrical device, so as to improve the user experience.
[0068] In order to further limit the rotation and movement trajectory of the drive arm 20, so that the movement of the panel 300 can be linked more smoothly with the rotation of the door body 200, the drive arm 20 has a middle section 23 between the first drive end 21 and the second drive end 22, and the second guide mechanism is provided between the middle section 23 and the hinge arm 10. The middle section 23 cooperates with the hinge arm 10 through a second guide mechanism. In this way, by further adding a restraint point between the hinge arm 10 and the drive arm 20, the movement trajectory of the drive arm 20 is more reliably restricted, and the force point of the hinge arm 10 on the drive arm 20 during the rotation process is increased, such that during the movement stroke of the door body 200 to open the main body 100, the first drive end 21 and the middle section 23 approach the door body 200. Since the driving force received by the drive arm 20 is more balanced, the drive arm 20 is driven more stably, and the jamming phenomenon is less likely to occur.
[0069] As shown in FIG. 1, FIG. 2 and FIG. 12 to FIG. 19, the hinge arm 10 includes a first arm 12 and a second arm 13, the first arm 12 is connected to the door body 200, the second arm 13 is elastically connected to the main body 100, and the second guide mechanism is provided between the second arm 13 and the drive arm 20. An included angle is formed between the first arm 12 and the second arm 13, the first connection portion 11 is formed at the connection between the first arm 12 and the second arm 13, and the first connection portion 11 is connected or rotatably connected with the rotating shaft 203.
[0070] On the basis of the above embodiment, as shown in FIG. 1, FIG. 2 and FIG. 12 to FIG. 19, the second guide mechanism includes a second guide pin 51 and a second guide groove 52, and the second guide pin 51 is inserted into the second guide groove 52. In this embodiment, the second guide groove 52 may be provided on the hinge arm 10, and the second guide pin 51 may be provided on the drive arm 20. In other embodiments, the second guide groove 52 may also be provided on the drive arm 20, and the second guide pin 51 may be provided on the hinge arm 10. In this embodiment, the second guide groove 52 is matched (inserted) with the second guide pin 51, so that the middle part of the drive arm 20 is constrained by the hinge arm 10. In this way, a constraint point is further added between the second arm 13 of the hinge arm 10 and the middle section 23 of the drive arm 20, such that the movement trajectory of the drive arm 20 is more reliably restricted, and the force point of the hinge arm 10 on the drive arm 20 during the rotation process is increased. Since the driving force received by the drive arm 20 is more balanced, the drive arm 20 is driven more stably, and the jamming phenomenon is less likely to occur.
[0071] In some embodiments, as shown in FIG. 1, FIG. 2, and FIG. 12 to FIG. 19, the second guide pin 51 is provided on the middle section 23, the second guide groove 52 is provided on the second arm 13, and the second guide pin 51 moves in the extension direction of the second guide groove 52. As shown in FIG. 2, the second guide groove 52 extends substantially in a straight line, for example, the second guide groove 52 may extend along the length direction of the second arm 13. As such, in this embodiment, during the rotation of the hinge arm 10, the middle part of the drive arm 20 is constrained by the hinge arm 10. The second guide groove 52 acts on the second guide pin 51 to drive the drive arm 20 to swing, the first drive end 21 of the drive arm 20 is constrained by the first guide groove 42, so that the second drive end 22 of the drive arm 20 drives the panel 300 to move relative to the door body 200. When the door body 200 is rotated and opened, the drive arm 20 drives the panel 300 to move relative to the door body 200 along the second direction and away from the fixed end 201. In the process of rotating and closing the door body 200, the drive arm 20 drives the panel 300 to move relative to the door body 200 along the second direction and close to the fixed end 201.
[0072] The second drive end 22 can be connected to the panel 300 in various ways. In this embodiment, as shown in FIG. 1 and FIG. 2, the hinge 500 further includes a slider 60 for fixing the panel 300. The first arm 12 is provided with a sliding groove 61 extending along the length direction of the first arm 12, and the drive arm 20 is rotatably connected with the slider 60 to realize the rotational connection with the panel 300. In some embodiments, the hinge arm 10 is provided with the sliding groove 61, and the slider 60 is slidably provided in the sliding groove 61, The second drive end 22 and the slider 60 are respectively provided with a pin 71 and a pin 71 hole, the pin 71 matches with the hole of the pin 71, so that the second drive end 22 is rotatably connected with the slider 60. In this embodiment, the setting of the slider 60 makes it more convenient to connect the panel 300, so that the second drive end 22 is rotatably matched with the panel 300 through the slider 60. In some embodiments, the slider 60 fixes the panel 300 through the mounting frame 80, so that the panel 300 is firmly fixed, the slider 60 makes the fixing of the panel 300 more reliable, and prevents the panel 300 from being separated from the door body 200 after being used for a long time. Of course, the slider 60 and the panel 300 can also be directly fixed with screws. At the same time, the slider 60 is rotatably connected with the second drive end 22, which is easy to assemble and disassemble, thereby reducing the maintenance cost of the hinge 500.
[0073] As can be seen from the above, the present disclosure provides a hinge 500, and the hinge 500 can be applied to an electrical device.
[0074] In some embodiments, the electrical device includes: a main body 100 having an inner cavity; a door body 200 rotatably connected to the main body 100 through the hinge 500 to open or close the inner cavity; a panel 300 movably provided on one side of the door body 200; and a hinge 500 of any of the above-mentioned embodiments.
[0075] When the door body 200 opens the main body 100 to open the inner cavity, the drive arm 20 moves along with the rotation of the hinge arm 10, the first drive end 21 of the drive arm 20 moves along the first guide groove 42 of the first guide mechanism and approaches the door body 200, the hinge arm 10 drives the drive arm 20 through the second guide mechanism. That is, when the hinge arm 10 rotates, the second guide mechanism can drive the drive arm 20 to move toward the door body 20, and because of the restraint of the first guide mechanism, the drive arm 20 is constrained to rotate following the rotation of the hinge arm 10, such that the middle section 23 of the drive arm 20 moves along the second guide groove 52 of the second guide mechanism and approaches the door body 200. Therefore, the second drive end 22 of the drive arm 20 can be driven to move in a direction away from the hinge 500, so that the panel 300 moves relative to the door body 200 in a direction away from the hinge 500. During the closing stroke of the door body 200, the panel 300 has an opposite movement stroke, which is not repeated here.
