    [0014] The following disclosure provides many different embodiments or examples, for realize different structures of the present disclosure. In order to simplify the present disclosure, the following will describe components and setting of specific examples. Certainly, thereby are just examples, and are not intended to limit the present disclosure. Furthermore, in the present disclosure, reference numerals and/or reference letters may be repeated in different embodiments. This repetition is for the purpose of simplicity and clarity, and does not indicate relationships among various embodiments and/or settings discussed herein.

    [0015] Referring to FIG. 1, a head-mounted display is provided in an embodiment of the present disclosure. The head-mounted display includes a display device 20, a headphone device 30, a head-mounted bracket 40, and a connection mechanism 50. The display device 20 includes a display body 21 with a displaying side 21A and support arms 22. The display side 21A is configured to project images to user eyes. The support arms 22 extend from two ends of the display body 21 in a direction A toward the displaying side 21A, which forms a shape similar to the shape of a pair of glasses. The headphone device 30 includes two headphone bodies 31 for outputting audio signals. The head-mounted bracket 40 includes a head-mounted portion 41 and connection portions 42 extending from two ends of the head-mounted portion 41. In the embodiment, the head-mounted display includes two connection mechanisms 50. Each of the two connection mechanisms 50 respectively connects one of the support arms 22 at two ends of the display body 21 to one corresponding headphone body 31 and one corresponding connection portion 42. Referring to FIGs. 2-4, each connection mechanism 50 includes a first rotation member 51 and a second rotation member 52. The first rotation member 51 connects one support arm 22 to the corresponding headphone body 31. The second rotation member 52 rotatably connects to the first rotation member 51, and further connects to the corresponding connection portion 42.

    [0016] The above embodiment of the present disclosure provides a head-mounted display including the connection mechanism 50. The connection mechanism 50 can connect the display device 20, the headphone device 30, and the head-mounted bracket 40. The connection mechanism 50 includes the first rotation member 51 for connecting the support arm 22 at one end to one corresponding headphone body 31, and the second rotation member 52 rotatably connecting to the first rotation member 51, and the second rotation member 52 further connects to the connection portion 42 at one end of the head-mounted bracket 40. The display device 20 and the head-mounted bracket 40 are driven to rotate relative to each other when the first rotation member 51 rotates relative around the second rotation member 52, which provides a flexible connection manner, thus the display device 20 and the head-mounted bracket 40 can be folded together to carry around, which enhances portability of the product.

    [0017] In the embodiment, at least one of the two connection mechanisms 50 includes a gear structure 53. The gear structure 53 includes a tooth-shaped structure 532. The tooth-shaped structure 532 is arranged at a circumferential wall 531 of the first rotation member 51 or that of the second member 52, and a resilient sheet 533 fixes to another one of the first rotation member 51 and the second rotation member 52 and engages with the tooth-shaped structure 532. The first rotation member 51 and the second rotation member 52 rotatably engage with each other through the tooth-shaped structure 532 and the resilient sheet 533 under an external force. With the engagement between the tooth-shaped structure 532 and the resilient sheet 533, the head-mounted bracket 40 keeps a relative angle with the display device 20. The resilient sheet 533 is deformed by an external force and slides relative to the tooth-shaped structure 532, which enables the display device 20 to rotate around an axis extending through the axle centers of the two headphone bodies 31. It should be noted that, only one of the connection mechanisms 50 supporting the gear structure 53, or both of the two connection mechanisms 50 supporting the gear structures 53, which ensure that the head-mounted bracket 40 keep a relative angle with the display device 20.

    [0018] In some cases, when both of the two connection mechanisms 50 include the gear structures 53, if the user exert an improper force, for example, when the display device 20 and the head-mounted bracket 40 are pulled toward one of the connection mechanisms 50, the forces applied to the two gear structures 53 are different and then the rotations of the two gear structures 53 are not consistent. Thus the head-mounted display may be broke down easily. This problem can be solved with only one of the connection mechanisms 50 with the gear structure 53, and the gear structure 53 set in only one of the connection mechanisms 50 drives the other connection mechanism 50 to rotate together with the one of the connection mechanisms 50.

    [0019] The above embodiment of the present disclosure includes the connection mechanism 50 for connecting the display device 20, the headphone device 30, and the head-mounted bracket 40. The connection mechanism 50 includes the gear structure 53 with the tooth-shaped structure 532 and the resilient sheet 533. Under an external fore, the connection mechanism 50 drives the display device 20 to rotate relative to the head-mounted bracket 40 by virtue of the rotation of the tooth-shaped structure 532 and the engaged resilient sheet 533, which provides a flexible connection manner to allow the display device 20 to be folded together with the head-mounted bracket 40, to enhance the portability of the product.

    [0020] Specifically, the first rotation member 51 includes a latching side 51A with a latching structure 54, and an opposite side 51B opposite to the latching side 51A. The second rotation member 52 includes a latching side 52A also with a latching structure 54 and an opposite side 52B opposite to the latching side 52A. The gear structure 53 is arranged at the latching sides 51A, 52A. In an embodiment, each of the first rotation member 51 and the second rotation member 52 is an annular frame, and includes an inner circumferential wall 51a or 52a and an outer circumferential wall 51b or 52b. The annulus radius of the first rotation member 51 is larger or smaller than that of the second rotation member 52. In an embodiment, the radius of the annulus of the first rotation member 51 is greater than that of the second rotation member 52. In the embodiment, the latching structure 54 of the first rotation member 51 includes a first joint portion 541 extending from the latching side 51A toward the center of the annulus, and a second joint portion 542 extending from the first joint portion 541 in a direction opposite to the opposite side 51B. Specifically, the second joint portion 542 can provide with the circumferential wall 531 and the tooth-shaped structure 532 of the gear structure 53. The latching structure 54 of the second rotation member 52 includes a third joint portion 543. The third joint portion 543 extends from the latching side 52A away from the center of the annulus. The first joint portion 541 fits with the third joint portion 543. Thus, the third joint portion 543 can be pressed to connect with the first joint portion 541 through the inner of the first rotation member 51, and the opposite side 52B extends out through the first rotating member 51, which enables the first rotation member 51 to rotatably engage with the second rotation member 52. The structure of another connection mechanism 50 is almost the same as the above, the difference between the two connection mechanisms 50 is that the resilient sheet 533 is not arranged in the another connection mechanism 50, or neither the mentioned resilient sheet 533 nor the tooth-shaped structure 532 are not arranged in the another connection mechanism 50. However, the present disclosure is not limited thereto, the radius of the annulus of the first rotation member 51 may be smaller than that of the second rotation member 52, and in which case, the latching structure 54 of the first rotation member 51 and the latching structure 54 of the second rotation member 52 in the above embodiment are exchanged correspondingly.

    [0021] For purpose of illustrating the above principle, the following in combination with an embodiment is for specifically illustration. In the embodiment, the radius of the annulus of the first rotation member 51 is greater than that of the second rotation member 52. However, the present disclosure is not limited thereto.

    [0022] The second joint portion 542 of the first rotation member 51 is a concentric annular ring extending from the annular frame, and includes an inner circumferential wall 542a and an outer circumferential wall 542b. In the embodiment, the circumferential wall 531 and the tooth-shaped structure 532 of the gear structure 53 are arranged at the second joint portion 542. Specifically, the tooth-shaped structure 532 is arranged at the inner circumferential wall 542a. It should be understood that the inner circumferential wall 542a can act as the circumferential wall 531 of the gear structure 53. The resilient sheet 533 of the gear structure 53 is fixed to the second rotation member 52. When the third joint portion 543 of the second rotation member 52 is pressed to connect with the first joint portion 541 by the inner portion of the first rotation member 51, the resilient sheet 533 engages with the tooth-shaped structure 532 correspondingly.

    [0023] Specifically, in the embodiment, a resilient sheet fixing portion 521 is arranged at the annular frame of the second rotation member 52. The resilient sheet fixing portion 521 is located at a position corresponding to the tooth-shaped structure 532 when the second rotation member 52 engages with the first rotation member 51. Specifically, in the embodiment, the resilient sheet fixing portion 521 is a limiting through hole with a shape corresponding to the shape of the resilient sheet 533. Part of the resilient sheet 533 is limited and fixed to the inner side of the second rotation member 52. Part of the resilient sheet 533 for engagement extends out through the limiting through hole and corresponds to the tooth-shaped structure 532. Preferably, in the embodiment, the second rotation member 52 includes two resilient sheet fixing portions 521. The resilient sheet 533 includes two portions which extend outside the fixing portions 521 and engage with the tooth-shaped structure 532. When one of the two portions is located in a gap between two adjacent teeth of the tooth-shaped structure 532, another portion stands against the tooth of the tooth-shaped structure 532. Therefore, the accuracy of a rotation location can achieve to a half of the teeth pitch of the tooth-shaped structure 532.

    [0024] In a preferred embodiment of the present disclosure, the first rotation member 51 and the second rotation member 52 utilize annular frames and connect to each other by utilizing the latching structure 54, thus to form an accommodating chamber by the annular frame. The accommodating chamber can accommodate electric components, such as PCB, batteries, or the like, which avoids the head-mounted display supplying a redundant structure for allocating additional accommodate space. Preferably, an outer cover with a latching structure can be arranged at the outer side of the accommodating chamber formed by the annular frames, which can be easily disassembled. Thus the components are allowed to be replaced, maintained, repaired, or the like easily.

    [0025] However, as long as that the resilient sheet 533 is rotatable relative to the tooth-shaped structure 532 and keeps engaging with the tooth-shaped structure 532, the first rotation member 51 and the second rotation member 52 in the present disclosure are not limited to the annular frames. For example, one of the first rotation member 51 and the second rotation ember 52 provides the tooth-shaped structure 532 and is a frame with an outer rectangle wall and an inner circular wall, and the tooth-shaped structure is mounted to the inner circular wall. Accordingly, another of the first rotation member 51 and the second rotation member 52 can be an embedded annular frame of the above embodiment, and can be a circular solid embedded in the circular cavity formed by the circular wall of the one of the first rotation member 51 and the second rotation member which provides the tooth-shaped structure 532, and the resilient sheet 533 is arranged at the circular outer wall of the circular solid and engages the tooth-shaped structure 532 correspondingly. It should be understood that, one of the first rotation member 51 and the second rotation member 52 which provides the tooth-shaped structure 532 may be an annular frame with a smaller radius, with the tooth-shaped structure 532 arranged at the outer circumferential wall of the annular frame. Another of the first rotation member 51 and the second rotation member 52 which provides the resilient sheet 533 can be of any shape with an inner circumferential wall corresponding to the outer circumferential wall of the one of the first rotation member 51 and the second rotation member 52, which enables the tooth-shaped structure 532 to be embedded in the inner circumferential wall. The resilient sheet 533 engages with the tooth-shaped structure 532 of the embedded one of the first rotation member 51 and the second rotation member 52 which provides the tooth-shaped structure 532 through the inner circumferential wall. An ordinary person skilled in the art constructs the relative engagement rotation of the first rotation member and the second rotation member according to the principles of the present disclosure should be included in the scope of the present disclosure.

    [0026] In the embodiment, the opposite side 51B of the first rotation member 51 connects to the corresponding headphone body 31. Specifically, the headphone body 31 connects to the first rotation member 51 by the fixing member 80. The fixing member 80 fixedly connects to the opposite side 51B of the first rotation member 51, and the headphone body 31 is fixed to the fixing member 80. The specific fixing manner can be riveted joint, and also can be any fixing manner provided by the art.

    [0027] Preferably, the head-mounted display 10 further includes a touch panel 60. The touch panel 60 is arranged at the opposite side 52B of the second rotation member 52. Specifically, referring to FIG. 6, the head-mounted display 10 may further include a cover 70. The cover 70 includes an opening portion 71 and a fixing portion 72. The touch panel 60 is fixed to the cover 70 and is exposed through the opening portion 71. The fixing portion 72 fixedly connects to the second rotation member 52. Specifically, as another embodiment of the head-mounted bracket 40 and the connection mechanism 50 shown in FIG. 5, the second rotation member 52 includes a fixed connection portion 525. Specifically, the fixed connection portion 525 is a rivet fixing hole, and the fixed connection portion 525 fixedly connects to the fixing portion 72 of the cover by rivets. In this embodiment, the connection end 42 of the head-mounted bracket 40 pivotally connects to the cover 70 via a pivot 421. The cover 70 includes a pivot hole 73, which enables the pivot 421 of the connection end 42 to extend through the pivot hole 73 to be fixed in the cover 70.

    [0028] In another embodiment, there is no cover 70 arranged on the head-mounted display 10, the connection end 42 of the head bracket 40 pivotally connects to the second rotation member 52 via a pivot. Specifically, referring to FIG. 6, the second rotation member 52 includes a pivot hole 522, which enables the pivot 421 of the connection end 42 to extend through the pivot hole 522 from the outer side of the second rotation member 52, and the connection end is further fixed to the inner side of the second rotation member 52 by a sleeve 523.

    [0029] However, the connection manner between the connection end 42 of the head-mounted bracket 40 and the connection mechanism 50 is not limited to the above specific embodiment. Referring to FIG. 1, the connection end 42 of the head-mounted bracket 40 can be integrally fixedly formed in the second rotation member 52 or the cover 70, and it can also connects to the second rotation member 52 or the cover 70 by an inserting manner, latching manner, or the like.

    [0030] In the above preferable embodiment, the head-mounted display achieves rotatable connection by virtue of the latching structures 54 of the first rotation member 51 and the second rotation member 52 of the connection mechanism 50. The head-mounted bracket 40 connects to the second rotation member 52, the support arms 22 of the display device 20 connect to the first rotation member 51, which enables the display device 20 and the head-mounted bracket 40 to rotate relative to each other under rotation of the first rotation member 51 and the second rotation member 52. The connection includes a direct connection, or an indirect connection via other component.

    [0031] In the above embodiment, the gear structure 53 enables the first rotation member 51 and the second rotation member 52 to rotate relative to each other under damping, such that an angle can be defined between the head-mounted portion 41 and the display body 21, and the head-mounted portion 41 and the display body 21 are rotatable relative to each other. It could be understood that structures which achieves the above function is not limited to the gear structure 53 of the present disclosure. For example, the structures may be two rubbers, as long as damping structures which cause the first rotation member 51 and the second rotation member 52 to rotate relative to each other under damping.

    [0032] The foregoing description is only the preferred embodiments of the present disclosure, but is not intended to limit the scope of the invention.
