[0010] In an embodiment, the first bracket and the second bracket rotate relative to each other about a first axis, and the elastically deformed direction of the first elastic member is arranged to intersect the first axis.

[0011] In an embodiment, the first elastic member and the limiting member are located on the side of the first axis, and the first bracket and the second bracket form a mounting channel at the first axis, and the mounting channel is used for the functional member extending from the frame to the temple to pass through.

[0012] In an embodiment, during the inward turning of the temple from the self-opening position, the limiting part is separated from the first elastic part and is spaced apart from the first elastic part to form an avoiding space, the avoiding space is communicated with the mounting channel, and the functional part can be partially accommodated in the avoiding space.

[0013] In an embodiment, the first elastic part comprises a mounting part, a deformation part and a pushed part connected in sequence, the mounting part is connected to the first support, the pushed part can be displaced towards the mounting part under the pushing action of the limiting part and promotes the elastic deformation of the deformation part.

[0014] In an embodiment, the midpoint connecting line of the deformation part is arranged in parallel with the first axis, the limiting part further comprises two intersecting cantilever parts, the first ends of the two cantilever parts are connected to different positions of the first support respectively, the second ends of the two cantilever parts are connected and connected to the limiting part, and the cantilever part and the limiting part are located in the plane of the midpoint connecting line of the deformation part.

[0015] In an embodiment, the deformation part comprises a first deformation structure and a second deformation structure connected in sequence, the first deformation structure is connected to the mounting part, and the second deformation structure is connected to the pushed part, the outward turning of the temple from the self-opening position comprises a first stage and a second stage occurring in sequence, in the first stage, the first deformation structure is deformed and the second deformation structure is not deformed, and in the second stage, the first deformation structure and the second deformation structure are deformed, and the elastic forces acting on the pushed part are reversely arranged to make the amplitude fluctuation of the clamping force of the temple keep within a preset percentage.

[0016] In an embodiment, the first deformation structure comprises a force receiving rod segment and two curved rod segments, the two curved rod segments are arranged at opposite ends of the force receiving rod segment, the force receiving rod segment is arranged opposite to the mounting part, and the curved rod segments are connected to the end of the force receiving rod segment and the end of the mounting part; the second deformation structure comprises a main rod segment and two wing rod segments, the main rod segment is connected between the pushed part and the middle part of the force receiving rod segment, and the two wing rod segments are arranged at opposite sides of the main rod segment, the wing rod segments are inclined to extend away from the main rod segment in the direction close to the force receiving rod segment, and the ends of the wing rod segments away from the main rod segment are adjacent to the force receiving rod segment.

[0017] In an embodiment, a midpoint connecting line of the deformation portion is arranged on a plane intersecting the first axis, the deformation portion comprises a first arc-shaped rod segment and a second arc-shaped rod segment with opposite convex directions, the first arc-shaped rod segment is connected to the mounting portion, and the second arc-shaped rod segment is convex towards the first axis; when the temple is in the open position, an end of the second arc-shaped rod segment away from the first arc-shaped rod segment is in abutment with the limiting portion.

[0018] In an embodiment, a second elastic member is clamped between the first support and the second support, the second elastic member is elastically deformed along the direction of the rotation axis of the first support, and is in an elastically deformed state at least during the inward turning of the temple from the open position.

[0021] In the technical solution of the application, the outward turning of the temple from the open position causes the second support to rotate relative to the first support and around the first axis, and causes the limiting member to push the first elastic member, so that the first elastic member is in an elastically deformed state. The first elastic member in the elastically deformed state generates a reaction force on the limiting member, and the reaction force is transmitted to the temple through the limiting member and the second support, so that the temple has a tendency to rotate towards the open position. It can be understood that the tendency of the temple to rotate towards the open position can increase the clamping force of the temple on the head of the user in the wearing state, which is conducive to the stable and reliable wearing of the glasses product, so that the temple can be well attached to the head, and the risk of the temple and the head-mounted display device slipping forward is reduced.

In addition, “and / or” or “and / or” appearing throughout the text means that the three parallel solutions are included, for example, “A and / or B” includes A solution, or B solution, or A and B solutions are satisfied at the same time. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of a person of ordinary skill in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope claimed by the present application.

[0046] The connection structure between the temples and the frame of the current head-mounted display device, such as but not limited to AR(Augmented Reality, augmented reality) glasses, VR(Virtual Reality, virtual reality) glasses, and MR(Mixed Reality, mixed reality) glasses, is usually a simple hinge structure. When a user with a larger head circumference wears it, the temples will turn outward and form an outward eight, and in addition, the clamping force of the temples on the user's head is weak, which causes the device to easily slide forward.

[0047] The application provides a temple connecting structure for connecting a temple and a frame of an eyewear product, for example, a temple of a head-mounted display device can be mounted on the frame through the temple connecting structure, so that the temple in a wearing state can generate a clamping force to be clamped on the head of a user, thereby improving the wearing stability of the head-mounted display device. The head-mounted display device is, for example but not limited to, an AR (Augmented Reality) glass, a VR (Virtual Reality) glass, and an MR (Mixed Reality) glass. Taking the AR glass as an example, the frame of the AR glass is usually provided with a display module to provide image information to the eyes of a user.

[0048] It should be noted that the temple gradually passes through a folding position, an opening position, and an eversion limit position in the process of gradually unfolding from the folding state. The free end of the temple is adjacent to or abuts against the frame in the folding position. The free end of the temple is away from the frame in the opening position or the eversion limit position. The temple has various wearing states between the opening position and the eversion limit position to allow users with different head sizes to normally wear the eyewear product.

[0049] Please refer to FIGS. 1 to 11, wherein FIGS. 1 to 3 and FIGS. 6 to 10 correspond to the state that the temple is in the opening position; FIG. 4 and FIG. 1 correspond to the state that the temple is in the eversion limit position; and FIG. 5 corresponds to the process state that the temple is in the opening position and is turned inward.

[0050] Please refer to FIGS. 1 to 5. In the first embodiment of the application, the temple connecting structure 101 is used for connecting the temple 102 and the frame 103. The temple connecting structure 101 comprises:

[0051] The first support 10 and the second support 20 are rotationally connected to each other. One of the first support 10 and the second support 20 is mounted on the temple 102, and the other is mounted on the frame 103;

[0052] The first elastic member 30 is arranged on the first support 10; and

[0053] The limiting member 40 is arranged on the second support 20 and has a limiting portion 41.

[0054] In the process that the temple 102 is turned outward from the opening position, the limiting portion 41 pushes the first elastic member 30, and the first elastic member 30 is in an elastically deformed state.

[0055] Please refer to FIG. 9 and FIG. 10, in the first to third embodiments, optionally, the first support 10 is arranged on the frame 103, and the second support 20 is arranged on the temple 102. It can be understood that in the present embodiment, the folding position of the second support 20 corresponds to the folding position of the temple 102, the opening position of the second support 20 corresponds to the opening position of the temple 102, the everted limit position of the second support 20 corresponds to the everted limit position of the temple 102, and the everted process of the second support 20 from the opening position corresponds to the everted process of the temple 102 from the opening position. Of course, in other embodiments, the first support 10 can be arranged on the temple 102 and the second support 20 can be arranged on the frame 103.

[0056] For the convenience of explanation, the following will take the embodiment in which the first support 10 is arranged on the frame 103 and the second support 20 is arranged on the temple 102 as an example to explain the scheme.

[0057] In the technical scheme of the present application, the everted operation of the temple 102 from the opening position causes the second support 20 to rotate relative to the first support 10 and around the first axis, and causes the limiting piece 40 to push the first elastic piece 30, so that the first elastic piece 30 is in an elastic deformation state. The first elastic piece 30 in the elastic deformation state will generate a reaction force on the limiting piece 40, and the reaction force is transmitted to the temple 102 through the limiting piece 40 and the second support 20, so that the temple 102 has a tendency to rotate towards its opening position. It can be understood that the temple 102 has a tendency to rotate towards its opening position, which can increase the additional clamping force of the temple 102 on the user's head in the wearing state, and this clamping force is conducive to the stable and reliable wearing of the eyewear product, so that the temple 102 can be well fitted on the head and the risk of the temple 102 and the head-mounted display device slipping forward can be reduced.

[0058] Please refer to FIG. 1, FIG. 6 and FIG. 8, in the first to third embodiments, optionally, the first support 10 and the second support 20 rotate relative to each other around the first axis, and the elastic deformation direction of the first elastic piece 30 is arranged intersecting the first axis. It should be noted that the elastic deformation direction of the first elastic piece 30 refers to the direction of the force acting on it by the limiting piece 40, which is usually parallel to the direction in which the structure of the first elastic piece 30 has the maximum deformation. It can be understood that since the elastic deformation direction of the first elastic piece 30 intersects the first axis, i.e., the elastic deformation direction of the first elastic piece 30 is roughly parallel to the plane in which the movement track of the temple 102 lies, the reaction force of the first elastic piece 30 can directly affect the everted operation of the temple 102 and form the clamping force of the temple 102. In this way, the action relationship between the first elastic piece 30 and the limiting piece 40 is direct and clear, and the structural features of the temple connecting structure 101 can be simplified.

[0059] Of course, in other embodiments, the elastic deformation direction of the first elastic member 30 can also be parallel or substantially parallel to the first axis. That is, the elastic deformation direction of the first elastic member 30 is substantially perpendicular to the plane in which the movement trajectory of the temple 102 lies.

[0060] Referring to FIGS. 3, 4 and 10, in the first to third embodiments, optionally, the first elastic member 30 and the limiting member 40 are located on the side of the first axis, and the first support 10 and the second support 20 are formed with a mounting channel 107 at the first axis, the mounting channel 107 being used for the functional member 104 extending from the frame 103 to the temple 102 to pass through. That is, the head-mounted display device of the present embodiment further comprises the functional member 104, the functional member 104 comprising at least one of a wire harness, a flexible printed circuit board and a flexible heat-conducting member, and the electronic components (e.g. a rechargeable battery) on the temple 102 and the electronic components (optics) on the frame 103 are electrically connected through the functional member 104. Hereinafter, the flexible printed circuit board will be taken as an example for illustration.

[0061] In this way, the mounting channel 107 is provided for the functional member 104, which can facilitate the installation and use of the functional member 104, and at the same time can reduce the weight of the temple connecting structure 101. Secondly, the mounting channel 107 is located on the first axis, which on the one hand enables the flexible printed circuit board to pass through the rotation center of the temple connecting structure 101, greatly reducing the length expansion and contraction amount of the flexible printed circuit board during the relative rotation of the first support 10 and the second support 20, thereby reducing the risk of bending of the flexible printed circuit board. On the other hand, the mounting channel 107 can provide a larger space for the flexible printed circuit board to bend, so that the flexible printed circuit board has a higher degree of freedom in the bending process and has a larger bending radius, thereby further reducing the risk of bending of the flexible printed circuit board and improving the service life of the device. On the other hand, the size of the temple connecting structure 101 in the thickness direction can be reduced.

[0062] Referring to FIGS. 4 and 10, in the first to third embodiments, optionally, the first axis is located on the side of the first elastic member 30 close to the inner side of the temple 102. It should be noted that the inner side of the temple 102 refers to the side facing the frame 103 when the temple 102 is in the folded position, that is, the side facing the user's head when the temple 102 is in the wearing state. In this way, it is beneficial to the displacement and expansion deformation of the flexible printed circuit board in the mounting channel 107, thereby further reducing the risk of bending of the flexible printed circuit board. Of course, in other embodiments, the first axis can also be located on the side of the first elastic member 30 away from the inner side of the temple 102.

[0063] Please refer to FIG. 1, FIG. 6 and FIG. 8, in the first to third embodiments, further, the side edge of the first support 10 is provided with two opposite first rotating parts 11, the second support 20 is provided with two opposite second rotating parts 21, the first rotating part 11 and the second rotating part 21 are hinged to realize the rotating connection of the first support 10 and the second support 20; one of the first rotating part 11 and the second rotating part 21 close to the limiting part 41 defines the installation channel 107. For example, in the embodiment shown in FIG. 8, the first rotating part 11 is closer to the limiting part 41, and the installation channel 107 is formed between the two first rotating parts 11; in the embodiment shown in FIG. 1, the second rotating part 21 is closer to the limiting part 41, and the installation channel 107 is formed between the two second rotating parts 21.

[0064] Please refer to FIG. 5, in the first embodiment, optionally, in the process of turning inwards from the open position, the limiting part 41 is separated from the first elastic member 30. In this way, the elastic member does not generate force on the temple 102 during the folding process of the temple 102, so that the folding operation of the temple 102 is more smooth and labor-saving. Of course, in other embodiments, the limiting part 41 can also continuously abut on the first elastic member 30 during the process of turning inwards from the open position.

[0065] Please refer to FIG. 5, in the first embodiment, optionally, in the process of turning inwards from the open position, the limiting part 40 and the first elastic member 30 are spaced to form an avoiding space 108, the avoiding space 108 is communicated with the installation channel 107, and the functional part 104 can be partially accommodated in the avoiding space 108. In this way, in the process of turning from the open position to the folded position, the avoiding space 108 can accommodate and store the length redundant part of the flexible printed circuit board, thereby facilitating to improve the bending service life of the equipment. Of course, in other embodiments, the avoiding space 108 can not be provided, or the limiting part 40 continuously abuts on the first elastic member 30.

[0066] It can be understood that the structure of the first elastic member 30 has various forms, for example, please refer to FIG. 2, FIG. 7 and FIG. 10, in the first to third embodiments, further, the first elastic member 30 includes an installation part 31, a deformation part 32 and a pushing part 33 connected in sequence, the installation part 31 is connected to the first support 10, the pushing part 33 can be displaced towards the installation part 31 under the pushing action of the limiting part 40, and the deformation part 32 is elastically deformed. In this way, the structure is simple and easy to realize. Of course, in other embodiments, the first elastic member 30 can be configured as a spring or a silica gel column, and the overall structure participates in the elastic deformation.

[0067] Please refer to FIG. 2 and FIG. 7, in the first and second embodiments, optionally, the plane where the midpoint connecting line of the deformation part 32 is arranged in parallel with the first axis, the limiting part 40 further comprises two cantilever parts 42 intersecting, the first ends of the two cantilever parts 42 are respectively connected at different positions of the first support 10, the second ends of the two cantilever parts 42 are connected and connected to the limiting part 41, the cantilever part 42 and the limiting part 41 are located in the plane where the midpoint connecting line of the deformation part 32 is located.

[0068] It should be noted that parallel refers to the state of parallel and near parallel; secondly, a plurality of cross sections are made along the direction perpendicular to the bending direction of the deformation part 32, the connecting line of the midpoints of the cross-sectional shapes cut by the plurality of cross sections is the midpoint connecting line of the deformation part 32. In this way, the deformation part 32, the cantilever part 42 and the limiting part 41 are located in the plane where the midpoint connecting line of the deformation part 32 is located, and are arranged in parallel with the first axis, which is beneficial to reduce the width dimension of the deformation part 32 and the limiting part 40 in the thickness direction of the temple connecting structure 101, thereby facilitating the thin design of the temple connecting structure 101 and the temple 102. Of course, in other embodiments, the plane where the midpoint connecting line of the deformation part 32 is arranged can intersect the first axis, for example, the embodiment shown in FIG. 10.

[0069] In order to improve the connection strength of the elastic part and the first support 10, in the first and second embodiments, optionally, the mounting part 31 is welded and fixed with the first support 10, and the cantilever part 42 is welded and fixed with the first support 10. Of course, in other embodiments, only the mounting part 31 can be welded and fixed with the first support 10, or only the cantilever part 42 can be welded and fixed with the first support 10.

[0070] Optionally, during the outward turning rotation of the temple 102 within the preset outward turning angle, the amplitude fluctuation of the clamping force of the temple 102 is kept within a preset percentage. That is, the clamping force of the temple 102 will not significantly increase with the increase of the outward turning angle of the temple 102, achieving the effect that the clamping force is basically constant when the temple 102 is turned outward, that is, making the clamping force of the temple 102 in the wearing state more stable, thus avoiding excessive clamping force on users with larger head circumference, and satisfying the consistency of wearing comfort of different head circumference groups, thereby improving the wearing comfort of the temple 102.

[0071] Optionally, the preset out-flanging angle is configured as 2° to 15°, and the preset percentage is configured as 10%. That is, within the out-flanging angle range of 2° to 15° from the open position of the temple 102, the amplitude fluctuation of the clamping torque is kept within 10%, for example, taking the clamping torque M = 200 N*mm as an example, the numerical value can be controlled between 180 N*mm and 220 N*mm, and the operation feeling and wearing comfort of the temple 102 are relatively ideal. Of course, in other embodiments, the preset out-flanging angle can also be configured as other values, such as 1°, 17°, 19°, or 20°, etc.; and the preset percentage can also be configured as other values, such as 5%, 7%, or 13%, etc.

[0072] It can be understood that there are various ways to achieve the effect that the clamping force of the temple 102 is basically constant when the temple 102 is out-flanged. For example, referring to FIGS. 6 and 7, in a second embodiment, the deformation part 32 includes a first deformation structure 34 and a second deformation structure 35 connected to each other, the first deformation structure 34 is connected to the mounting part 31, and the second deformation structure 35 is connected to the pushed part 33. The process of the temple 102 out-flanging from the open position includes a first stage and a second stage occurring in sequence. In the first stage, the first deformation structure 34 deforms and the second deformation structure 35 does not deform. In the second stage, the first deformation structure 34 and the second deformation structure 35 both deform, and the elastic force acting on the pushed part 33 is reversely arranged, so that the amplitude fluctuation of the clamping force of the temple 102 is kept within a preset percentage.

[0073] Please understand in combination with FIG. 12 that the first stage of the temple 102 out-flanging from the open position corresponds to the stage of the curve sharply rising in FIG. 12. At this time, only the first deformation structure 34 elastically deforms, and as the out-flanging angle of the temple 102 increases, the deformation amount of the first deformation structure 34 gradually increases, and the elastic force generated by the first deformation structure 34 to the pushed part 33 also gradually increases, so that the reaction force generated by the pushed part 33 to the limiting part 40 also gradually increases, and finally the clamping force of the temple 102 gradually increases. The second stage of the temple 102 out-flanging from the open position corresponds to the stage of the curve being relatively flat (the clamping force value is basically constant) in FIG. 12. At this time, the first deformation structure 34 and the second deformation structure 35 both elastically deform, and the elastic force (defined as the first force) generated by the first deformation structure 34 to the pushed part 33 continues to increase, but since the elastic force (defined as the second force) generated by the second deformation structure 35 to the pushed part 33 is opposite to the force direction of the first force, and the first force is also gradually increasing, it is equivalent that part of the first force is continuously offset by the second force, so that the total force formed by the first force and the second force is maintained at a certain value, or fluctuates within a small range around the value, and finally the clamping force of the temple 102 out-flanging is constant, that is, the amplitude fluctuation of the clamping force of the temple 102 is kept within a preset percentage.

[0074] Referring to FIG. 7, in the second embodiment, further, the first deformation structure 34 includes a force-bearing rod segment 341 and two curved rod segments 342, the two curved rod segments 342 being respectively arranged at opposite ends of the force-bearing rod segment 341, the force-bearing rod segment 341 being arranged opposite to the mounting portion 31, the curved rod segments 342 being connected at the ends of the force-bearing rod segment 341 and the ends of the mounting portion 31; the second deformation structure 35 includes a main rod segment 351 and two side wing rod segments 352, the main rod segment 351 being connected between the force-receiving portion 33 and the middle of the force-bearing rod segment 341; the two side wing rod segments 352 being respectively arranged at opposite sides of the main rod segment 351, the side wing rod segments 352 being inclined to extend away from the main rod segment 351 in a direction close to the force-bearing rod segment 341, and the ends of the side wing rod segments 352 away from the main rod segment 351 being adjacent to the force-bearing rod segment 341. In this way, the structure is simple and easy to implement.

[0075] Specifically, in the first stage of the out-flipping of the temple 102 from the open position, the stopper 40 pushes the force-receiving portion 33 through the stop portion 41 to cause the main rod segment 351 to exert pressure on the middle of the force-bearing rod segment 341, the force-bearing rod segment 341 and the curved rod segments 342 elastically deform, and the curved rod segments 342 mainly elastically deform and provide the force-receiving portion 33 with the main elastic force (i.e., the first force), at this time, the direction of the first force is from the mounting portion 31 to the force-receiving portion 33, and the first force is transmitted to the force-receiving portion 33 through the main rod segment 351.

[0076] In the second stage of the out-flipping of the temple 102 from the open position, the deformable space of the curved rod segments 342 becomes limited, causing the force-bearing rod segment 341 to gradually increase its contribution to the elastic force (i.e., the first force) and causing the two ends of the force-bearing rod segment 341 to gradually approach and abut against the first ends of the side wing rod segments 352. Since the second ends of the side wing rod segments 352 are fixed to the main rod segment 351 and are constrained by the main rod segment 351, the first ends of the side wing rod segments 352 will elastically deform around the second ends thereof after being pushed by the ends of the force-bearing rod segment 341. In contrast, the elastically deformed side wing rod segments 352 will generate a reaction force on the main rod segment 351, the reaction force being transmitted to the force-receiving portion 33 through the main rod segment 351 and appearing as the elastic force (i.e., the second force) of the side wing rod segments 352 on the force-receiving portion 33, at this time, the direction of the second force is from the force-receiving portion 33 to the mounting portion 31.

[0077] It can be understood that the side wing rod segment 352 does not participate in elastic deformation in the first stage, and starts to participate in elastic deformation in the second stage, and the elastic force (i.e., the second force) generated by the side wing rod segment 352 to the pushed part 33 can offset the increment of the elastic force (i.e., the first force) caused by the further deformation of the force-bearing rod segment 341 and the bending rod segment 342, so as to maintain the reaction force of the pushed part 33 applied to the limiting part 41 at a certain value, and exhibit the effect of constant clamping force of the out-toeing of the glasses leg 102.

[0078] Please refer to FIG. 8 and FIG. 10, in the third embodiment, optionally, the plane where the midpoint connecting line of the deformation part 32 is located intersects the first axis, the deformation part 32 includes the first arc-shaped rod segment 361 and the second arc-shaped rod segment 362 with opposite convex directions, the first arc-shaped rod segment 361 is connected to the mounting part 31, and the second arc-shaped rod segment 362 is convex towards the first axis; when the glasses leg 102 is in the open position, the end of the second arc-shaped rod segment 362 away from the first arc-shaped rod segment 361 abuts against the limiting part 41.

[0079] Please refer to FIG. 8, in the third embodiment, optionally, the limiting part 41 extends along the direction of the first axis, and the end is connected to the first support 10. Specifically, in the embodiment where the second support 20 has the second rotating part 21, the two ends of the limiting part 41 are respectively connected to the second rotating part 21. In this way, the limiting part 41 is simple in structure and easy to implement. In this embodiment, the limiting part 41 is optionally integrally formed with the second support 20. In this way, the production process of the glasses leg connecting structure 101 can be simplified, and the production efficiency can be improved.

[0080] Please refer to FIG. 1, FIG. 6 and FIG. 8, in the first to third embodiments, further, the second elastic member 50 is clamped between the first support 10 and the second support 20, the second elastic member 50 elastically deforms along the direction of the first axis, and is at least in the elastic deformation state in the process of the glasses leg 102 turning in from the open position. In this way, the second elastic member 50 is clamped and compressed by the first support 10 and the second support 20, and in the process of the glasses leg 102 turning in from the open position, the compressed second elastic member 50 will generate dynamic friction with the abutting surface of the first support 10 and the second support 20, and provide damping force in the rotating process of the first support 10 and the second support 20, preventing the glasses leg 102 from swinging randomly in the process of equipment taking, placing and transferring, that is, the posture of the glasses leg 102 can be maintained. Of course, in other embodiments, the second elastic member 50 can also not be provided.

[0081] Optionally, the second elastic member 50 is configured as a disc spring. Of course, in other embodiments, a bellows spring or other elastic body such as a silica gel body can also be used as the second elastic member 50.

[0082] Referring to FIG. 1, FIG. 6 and FIG. 8, in the embodiment in which the first support 10 has the first rotating part 11 and the second support 20 has the second rotating part 21, optionally, the second elastic member 50 is clamped between the first rotating part 11 and the second rotating part 21. In this way, the structure is simple and easy to assemble. Of course, in other embodiments, the second elastic member 50 can also be arranged at other positions on the first support 10 and the second support 20.

[0083] Referring to FIG. 9 and FIG. 10, the present application also proposes a head-mounted display device, which comprises a frame 103, a temple 102 and the aforementioned temple connecting structure 101.

The temple 102 is installed on the frame 103 through the temple connecting structure 101.

[0084] Further, when the temple 102 is in the open position, the temple 102 and the frame 103 are spaced apart to form a gap 106, and the head-mounted display further comprises a protective cover 105 arranged in the gap 106 to cover at least part of the structure of the temple connecting structure 101 exposed in the gap 106. In this way, the protective cover 105 can not only protect the part of the temple connecting structure 101 and the functional member 104 exposed in the gap 106, but also improve the neatness and beauty of the head-mounted display device at the connection of the temple 102. Of course, in other embodiments, the protective cover 105 can also not be arranged.

[0085] Optionally, referring to FIG. 11, when the temple 102 is in the extreme outward turning position, the inner side surfaces of the temple 102 and the frame 103 abut against each other to limit the extreme position of the temple 102, and at this time, the gap 106 at the inner side of the temple 102 is zero gap.

[0086] In order to further improve the protection performance of the protective cover 105, further, the protective cover 105 extends around the circumferential direction of the rotation axis of the first support 10 and comprises a first protective cover 105a and a second protective cover 105b which are spliced, and the first protective cover 105a and the second protective cover 105b are arranged on opposite sides of the gap 106. That is, the protective cover 105 shields both the inner and outer sides of the gap 106, thereby improving the protection effect and further improving the beauty of the device. Of course, in other embodiments, the protective cover 105 can also be arranged on one side of the gap 106.

[0087] The mounting mode of the protective cover 105 and the temple connecting structure 101 has various modes, and the present application does not make specific limitation thereon. For example, the first protective cover 105a can be mounted on the first support 10 or the second support 20 by clamping and / or screwing, and the second protective cover 105b can be mounted on the first protective cover 105a by welding or bonding.
