    Description

    BACKGROUND


    Technical Field



    [0001] The present invention relates to a head-mounted display device, and particularly relates to a head-mounted display device capable of improving wearing comfort.

    Description of Related Art



    [0002] Along with quick development of science and technology industry, types, functions, and usage of display devices are becoming more diverse, and wearable display devices that may be directly attached to the user's body are also developed. There are quite a lot of types of head-mounted display devices, and taking an eyemask type head-mounted display device as an example, after a user wears such type of the display device, besides that the user may view three-dimensional images, the images may be changed along with turning of user's head, which provides the user with a more immersive experience.

    [0003] However, some users may feel uncomfortable after wearing most of the head-mounted display devices on the market, because most of the head-mounted display devices on the market have headband and cushion designs that are not suitable for head shapes of these users. Therefore, how to make the head-mounted display device more stably worn on the user's head while also providing a more comfortable use experience to the user is a very important subject in the field.

    [0004] US 6 388 640 B1 discloses a head mounted display device of which a user can change the shape of the side frames by applying external forces. When the user mounts the side frames on the head the side frames including rear mount pads fit on the head of the user.

    [0005] JP H11 119148 A discloses a head mounted display device including a rotatable forehead pad part. When a forehead pad part is rotated, a rotation range is restricted by mutually abutting parts of the rear face of a front frame and a front face of a pad cover.

    [0006] US 2002/118506 A1 discloses a head mounted display device including a position adjusting mechanism. Shafts are provided with gears, respectively. In a state in which an unlock button is not pressed, lock members are urged by plate springs to positions at which the rotation of the gears is inhibited, respectively. When the unlock button is pressed, an integrated unlock lever also moves, so that parts of the lever intrude into square holes formed in the lock members, respectively. The parts are provided with a taper. By the intrusion of the parts, the tapers is guided to move into the square holes to move the lock members against the urging forces of the plate springs. Thereby, the lock members are moved to positions at which the rotation of the gears is permitted, so that the equipment and the support portion attached to the shafts can be rotated around the shaft. When the unlock button is released, the button is returned to the original position by a compression spring, so that the lock members return to the original positions. Thereby, the shafts are locked again.

    SUMMARY



    [0007] The present invention is directed to a head-mounted display device, which is capable of matching with head shapes of different users, such that the users can more stably wear the head-mounted display device to improve wearing comfort of the user.

    [0008] The present invention provides a head-mounted display device including a wearable assembly, at least one cushion and at least one adjustable fixing assembly. The wearable assembly is adapted to be worn on a head of a user. The at least one cushion is adapted to contact the head of the user, and is floatingly connected to the wearable assembly. The at least one adjustable fixing assembly includes a first positioning structure and a second positioning structure. The first positioning structure is connected to the wearable assembly, and the second positioning structure is connected to the at least one cushion. A structural interference generated between the first positioning structure and the second positioning structure positions the at least one cushion to the wearable assembly. The structural interference is a structural locking or friction generated between the first and the second positioning structure by an external force.

    [0009] Based on the above description, in the head-mounted display device of the present invention, the wearable assembly is adapted to be worn on the head of the user, the at least one cushion is floatingly connected to the wearable assembly, and is adapted to contact the head of the user when the wearable assembly is worn on the head of the user.

    [0022] Referring to FIG. 3A and FIG. 3B, FIG. 3B illustrates the first cushion 120A of FIG. 3A subjected to the first external force F1 is only translated towards the eye contact portion 114a without being rotated, and the second cushion 120B subjected to the second external force F2 is only translated towards the rotation mechanism 114c without being rotated. When the first cushion 120A is subjected to the first external force F1 to drive the second positioning structure to move towards the first positioning structure relative to the eye contact portion 114a and the two opposite ends of the first cushion 120A are translated towards each other under the function of the first external force F1 to make the first interference portion 132A to be moved between two adjacent second interference portions 134A to engage with the two adjacent second interference portions 134A, the mutual engagement between the first positioning structure and the second positioning structure positions the first cushion 120A to the wearable assembly 110. When the first positioning structure and the second positioning structure are structurally interfered to position the first cushion 120A to the eye contact portion 114a, the first upper side 124A1 and the first lower side 124A2 of the first cushion 120A contact the frontal bone of the user at the same time, so that the first cushion 120A is matched with a head shape of the user, which avails the user more stably wearing the head-mounted display device 100 on the head, and improving comfort of the user wearing the head-mounted display device 100.

    [0023] Similarly, when the second cushion 120B is subjected to the second external force F2 to drive the fourth positioning structure to move towards the third positioning structure relative to the rotation mechanism 114c and the two opposite ends of the second cushion 120B are translated towards each other under the function of the second external force F2 to make the third interference portion 132B to be moved between two adjacent fourth interference portions 134B to engage with one of the two adjacent fourth interference portions 134B, the mutual engagement between the third positioning structure and the fourth positioning structure positions the second cushion 120B to the wearable assembly 110. When the third positioning structure and the fourth positioning structure are structurally interfered to position the second cushion 120B to the rotation mechanism 114c, the second lower side 124B1 and the second upper side 124B2 of the second cushion 120B contact the occipital bone of the user at the same time, so that the second cushion 120B is matched with a head shape of the user, which avails the user more stably wearing the head-mounted display device 100 on the head, and improving comfort of the user wearing the head-mounted display device 100.

    [0024] FIG. 4A is a schematic cross-sectional view of the cushions of the head-mounted display device of FIG. 1A rotated relative to the wearable assembly after being subjected to the external force. FIG. 4B is a schematic cross-sectional view of the cushions of the head-mounted display device of FIG. 4A positioned to the wearable assembly after being subjected to the external force. For clarity of representation and convenience of description, the first sliding channels 114a1, the second sliding channels 114c1, the first sliding portions 122A1 and the second sliding portions 122B1 are shown by dashed lines in FIG. 4A and FIG. 4B. Referring to FIG. 4A and FIG. 4B, FIG. 4A illustrates a schematic diagram that the first cushion 120A of FIG. 3A subjected to the first external force F1 is translated towards the eye contact portion 114a and is rotated, and the second cushion 120B subjected to the second external force F2 is translated towards the rotation mechanism 114c and is rotated. When the first cushion 120A is subjected to the first external force F1 to drive the second positioning structure to move towards the first positioning structure relative to the eye contact portion 114a and the two opposite ends of the first cushion 120A are translated towards each other under the function of the first external force F1, and the first cushion 120A is rotated relative to the eye contact portion 114a to make the first interference portion 132A to be moved between two adjacent second interference portions 134A to engage with the two adjacent second interference portions 134A, the mutual engagement between the first positioning structure and the second positioning structure positions the first cushion 120A to the wearable assembly 110. When the first positioning structure and the second positioning structure are structurally interfered to position the first cushion 120A to the eye contact portion 114a, the first upper side 124A1 and the first lower side 124A2 of the first cushion 120A contact the frontal bone of the user at the same time. In other words, when the head-mounted display device 100 is worn on a head of a user with a different head shape, the first cushion 120A may be rotated by a different angle relative to the eye contact portion 114a in response to the head shapes of different users, so that the head-mounted display device 100 may be matched with head shapes of different users, which avails the user more stably wearing the head-mounted display device 100 on the head, and improving comfort of the user wearing the head-mounted display device 100.

    [0025] Similarly, when the second cushion 120B is subjected to the second external force F2 to drive the fourth positioning structure to move towards the third positioning structure relative to the rotation mechanism 114c and the two opposite ends of the second cushion 120B are translated towards each other under the function of the second external force F2, and the second cushion 120B is rotated relative to the rotation mechanism 114c to make the third interference portion 132B to be moved between two adjacent fourth interference portions 134B to engage with one of the two adjacent fourth interference portions 134B, the mutual engagement between the third positioning structure and the fourth positioning structure positions the second cushion 120B to the wearable assembly 110. When the third positioning structure and the fourth positioning structure are structurally interfered to position the second cushion 120B to the rotation mechanism 114c, the second lower side 124B1 and the second upper side 124B2 of the second cushion 120B contact the occipital bone of the user at the same time. In other word, when the head-mounted display device 100 is worn on a head of a user with a different head shape, the second cushion 120B may be rotated by a different angle relative to the rotation mechanism 114c in response to the head shapes of different users, so that the head-mounted display device 100 may be matched with head shapes of different users, which avails the head-mounted display device 100 can be more stably worn on the heads of different users, and improving comfort of the user wearing the head-mounted display device 100.

    [0026] In the embodiment, the number and configuration positions of the cushions may be adjusted according to an actual requirement. For example, the head-mounted display device 100 may be only configured with a single first cushion 120A or a single second cushion 120B, or configured with both of the first cushion 120A and the second cushion 120B. In other embodiments, the cushions may be configured on at least one of the eye contact portion 114a, the extension portion 114b and the rotation mechanism 114c to contact different parts of the user's head.

    [0027] Moreover, the first support portion 122A, the first sliding portion 122A1 and the second interference portion 134A of the second positioning structure are, for example, formed integrally, but may also be assembled from different members in other embodiments. Similarly, the second support portion 122B, the second sliding portion 122B1 and the fourth interference portion 134B of the fourth positioning structure are, for example, formed integrally, but may also be assembled from different members in other embodiments.

    [0028] On the other hand, referring to FIG. 1A, the eye contact portion 114a includes a first position limiting portion 114a2, the first support portion 122A of the first cushion 120A includes a second position limiting portion 122A2 corresponding to the first position limiting portion 114a2, and the first position limiting portion 114a2 and the second position limiting portion 122A2 are configured to limit rotation of the first cushion 120A relative to the eye contact portion 114a. Moreover, structures the same as the first position limiting portion 114a2 and the second position limiting portion 122A2 may also be configured between the second cushion 120B and the rotation mechanism 114c to limit rotation of the second cushion 120B relative to the rotation mechanism 114c, and details thereof are not repeated.
