[0058] The present application provides a temple connecting structure.

[0059] In an embodiment of the present application, as shown in Figures 1 to 4 and Figures 13 to 16 The temple connecting structure is applied to a head-mounted display device, the head-mounted display device includes a frame 10 and two temples 20 arranged at both ends of the frame 10, wherein the extension direction of the frame 10 is Q, the extension direction of the temple 20 is W, and the temple connecting structure comprises:

[0060] A mounting member 100 is fixedly connected to the frame 10;

[0061] A movable member 200 is movably mounted on the mounting member 100, and the movable member 200 is connected with a first elastic member 410, and the first elastic member 410 is configured in an axial deformation state; and

[0062] A connecting member 300 is fixedly connected to the temple 20, and the rotation axis of the connecting member 300 intersects with the axial direction of the first elastic member 410;

[0063] When the connecting member 300 is everted from the open position, it can act on the movable member 200, so that the elastic force of the elastic member 410 can react on the connecting member 300, thereby providing clamping force for the temple 20.

[0064] In the technical scheme, the connecting piece 300 has a folding position and an opening position, and the temple 20 is fixedly connected to the connecting piece 300. When the connecting piece 300 is in the folding position, the temple 20 is in a folded state, and the temple 20 and the frame 10 are stacked. When the connecting piece 300 is in the opening position, the temple 20 is in an opened state, and the temple 20 and the frame 10 are substantially at a 90-degree angle. When the user wears the head-mounted display device, the temple 20 will be folded outward compared to the opened state, and the connecting piece 300 will be correspondingly folded outward from the opening position. At this time, the connecting piece 300 can act on the movable piece 200, and the connecting piece 300 can be subjected to the elastic force of the first elastic piece 410. Since the axial direction of the first elastic piece 410 intersects the rotation axis of the connecting piece 300, the rotation axis of the connecting piece 300 is the rotation axis of the temple 20, so that the elastic force of the first elastic piece 410 has a component in the folding direction of the temple 20, so that the elastic force of the first elastic piece 410 can provide additional clamping force for the temple 20, thereby improving the clamping force of the temple 20 on the head of the user, and improving the wearing stability of the head-mounted display device.

[0065] In addition, the first elastic piece 410 is initially configured in an axial deformation state. Once the connecting piece 300 acts on the movable piece 200, the elastic force of the first elastic piece 410 can provide additional clamping force for the temple 20. During the folding process of the connecting piece 300, the clamping force provided by the first elastic piece 410 does not have to start from 0. It can be understood that if the initial state of the first elastic piece 410 is a natural state, i.e., no deformation state, if the first elastic piece 410 is to provide clamping force for the temple during the folding of the connecting piece 300, the elastic deformation of the first elastic piece 410 will increase with the increase of the folding angle. When a user with a large head size wears it, the clamping force received by the user will be too large due to the large folding angle, which will cause discomfort during wearing. In the technical scheme, by initially configuring the first elastic piece 410 in an axial deformation state, the clamping force provided by the first elastic piece 410 for the temple 20 does not have to be provided by forcing the first elastic piece 410 to elastically deform. Therefore, the clamping force provided by the first elastic piece 410 can be maintained within a certain range, so that the user can receive a relatively stable clamping force.

[0066] In the outer folding process, the connecting piece 300 can maintain the first elastic piece 410 in the initial deformation state, or change the elastic deformation amount of the first elastic piece 410 and the angle of the first elastic piece 410 relative to the mounting piece 100, so as to simultaneously change the elastic force size and direction of the first elastic piece 410, thereby being able to offset the change of the elastic force size of the first elastic piece 410 by the change of the elastic force direction of the first elastic piece 410. In this way, the force transmitted by the first elastic piece 410 to the connecting piece 300 through the movable piece 200 can be maintained within a certain range, which is beneficial to maintain the amplitude fluctuation of the clamping force provided by the first elastic piece 410 for the temple 20 within a preset percentage, and when worn by users with different head circumferences, a comfortable clamping force can be felt, which is beneficial to improve the wearing comfort of the head-mounted display device.

[0067] In addition, the connecting piece 300 can act on the movable piece 200 in a detachable manner. When the connecting piece 300 is folded from the open position, the connecting piece 300 can be separated from the movable piece 200. Specifically, when the connecting piece 300 is in the folded position, the connecting piece 300 and the movable piece 200 do not contact each other, and the connecting piece 300 contacts the movable piece 200 only when the connecting piece 300 is rotated to the open position. When the connecting piece 300 is folded from the open position, the connecting piece 300 can act on the movable piece 200, so that the temple 20 obtains additional inward clamping force. In this way, when the connecting piece 300 is between the folded position and the open position, the clamping force provided by the first elastic piece 410 will not be affected, and the first elastic piece 410 will not interfere with the switching of the temple 20 between the folded state and the open state.

[0068] Specifically, the first elastic piece 410 can be a tension spring or a compression spring. When the first elastic piece 410 is configured as a tension spring, the matching position of the connecting piece 300 and the movable piece 200 is closer to the temple 20 than the rotation axis of the connecting piece 300. When the first elastic piece 410 is configured as a compression spring, the matching position of the connecting piece 300 and the movable piece 200 is farther away from the temple 20 than the rotation axis of the connecting piece 300. In this way, the elastic force of the first elastic piece 410 provides inward clamping force for the temple 20.

[0069] In an embodiment, referring to Figure 5 and Figure 6 , the first end of the pushing arm 310 is used to push the sliding piece 210, the second end of the pushing arm 310 is fixedly connected to the temple 20, and the pushing arm 310 is rotatably connected to the mounting piece 100 between the two ends. In this way, the temple 20 and the pushing arm 310 form a lever at the rotation connection point of the pushing arm 310 and the mounting piece 100. According to the principle of the lever, the size of the clamping force F x and the size of the elastic force F2 satisfy:

[0070] Fx x2=F N x1

[0071] x2 is the distance from the position where the user's head and the temple 20 contact to the rotation axis of the connecting piece 300, the change of x2 is negligible, thus, when the elastic force F N remains unchanged, the clamping force F x can also remain unchanged. In the technical solution of the present application, even if the angle of the temple 20 varus changes, as long as the force transmitted by the first elastic member 410 to the pushing arm 310 through the movable member 200 can be maintained within a certain range, the size of the clamping force generated by the temple 20 under the action of the first elastic member 410 can tend to be constant. When users with different head circumferences wear the head-mounted display device, even if the angle of the temple 20 varus is different, the clamping force can be relatively constant, thus, the fit of the head-mounted display device is better, which is conducive to improving the wearing comfort of the user.

[0072] It can be understood that in the embodiment, through the lever structure, even if the direction of the elastic force F N changes, as long as the size of the elastic force F N remains unchanged, the size of the clamping force F x also remains unchanged. Of course, in other embodiments, the foregoing function can also be achieved through a fixed pulley mechanism. Specifically, a fixed pulley can be arranged at the pivot joint of the connecting piece, and the movable member and the connecting piece are connected through a non-elastic traction rope, and the traction rope is wound on one side of the fixed pulley, wherein the connecting piece is connected to the traction rope at the end close to the temple. In this way, when the size of the force acting on one end of the traction rope by the movable member remains unchanged, the tension of the other end of the traction rope on the connecting piece can also provide a relatively stable clamping force for the temple.

[0073] Further, in the embodiment, when the connecting piece 300 varus from the open position, the deformation amount of the first elastic member 410 gradually increases, and the included angle between the direction of the force of the movable member 200 on the pushing arm 310 and the axial direction of the first elastic member 410 gradually increases. Please refer to Figure 5 and Figure 6 It can be understood that when the temple 20 varus, the elastic force F k of the first elastic member 410 acting on the movable member 200 has a component in the direction of the abutment between the movable member 200 and the pushing arm 310, which will act on the pushing arm 310, that is, the elastic force F N of the pushing arm 310 from the movable member 210, that is, F N = k cosθ, wherein θ is the included angle between the axial direction of the first elastic member 410 and the direction of the force of the movable member 200 on the pushing arm 310;

[0074] In this embodiment, when the angle of the connecting member 300 is increased, the elastic deformation of the first elastic member 410 increases, that is, F k increases, and the angle θ between the axial direction of the first elastic member 410 and the direction of the force of the movable member 200 on the push arm 310 will increase, and cosθ will also decrease, F k The increment of cosθ and the decrement of cosθ can offset each other, so that the elastic force F on the push member 310 is N The change is minimal, or even virtually constant. That is, in the technical solution of the present invention, even if the angle of the temple 20 eversion changes, the clamping force generated by the temple 20 under the action of the first elastic member 410 can be kept constant. When users with different head circumferences wear the head-mounted display device, even if the angle of the temple 20 eversion varies, they can still experience a relatively constant clamping force. This improves the adaptability of the head-mounted display device and enhances the user's wearing comfort.

[0075] In one embodiment, if Figures 2 to 4 As shown, the movable part 200 includes a sliding part 210, and the mounting part 100 is provided with a slide groove 101. The extension direction of the slide groove 101 is set at an angle to the axial direction of the first elastic part 410. The sliding part 210 is slidably connected to the slide groove 101. When the connecting part 300 is turned outward from the open position, it can push the sliding part 210 to slide along the slide groove 101, so that the magnitude and direction of the elastic force of the first elastic part 410 are changed.

[0076] Due to the extension direction of the sliding groove 101 is also arranged at an angle with the rotation axis of the connecting piece 300, when the connecting piece 300 is turned relative to the mounting piece 100 to be turned outward, the connecting piece 300 can push against the sliding piece 210, so that the sliding piece 210 slides in the sliding groove 101. Due to the extension direction of the sliding groove 101 is arranged at an angle with the axial direction of the first elastic piece 410, when the sliding piece 210 slides in the sliding groove 101, the distance between the two ends of the first elastic piece 410 will change, thereby causing the axial deformation of the first elastic piece 410, changing the elastic force of the first elastic piece 410. At the same time, after the first elastic piece 410 is driven by the sliding piece 210, the axial direction of the first elastic piece 410 will change, so that the direction of the elastic force of the first elastic piece 410 changes. In this way, the change of the elastic force of the first elastic piece 410 can be offset by the change of the direction of the elastic force of the first elastic piece 410, so that the clamping force provided by the first elastic piece 410 to the temple 20 tends to be constant, and users with different head circumferences can feel comfortable clamping force when wearing, which is beneficial to improve the adaptability of the head-mounted display device. Of course, in other embodiments, the sliding groove 101 can not be provided, and the connecting piece 300 can be engaged with the sliding piece 210 on the side farther away from the temple 20 relative to the rotation axis of the connecting piece 300, to limit the movement track of the sliding piece 210 driven by the connecting piece 300, and the mounting piece 100 can be provided with a avoiding slot corresponding to the movement track of the sliding piece 210.

[0077] Specifically, as shown in Figure 3 and Figure 4 , the sliding groove 101 is provided with an arc-shaped wall 102, and the sliding piece 210 is pushed by the connecting piece 300 and slides along the arc-shaped wall 102, and can rotate around the axis of the arc-shaped wall 102. Among them, the arc-shaped wall 102 is convex towards the first elastic piece 410, that is, the center of the arc-shaped wall 102 is on the side away from the first elastic piece 410, so that during the sliding process of the sliding piece 210 along the arc-shaped wall 102, the distance between the end of the first elastic piece 410 away from the sliding piece 210 and the sliding piece 210 can change, so that the deformation amount of the first elastic piece 410 changes and drives the first elastic piece 410 to move, so that its axial direction changes. Of course, in other embodiments, the sliding groove 101 can also be provided as an inclined straight groove.

[0078] In an embodiment, as shown in Figures 2 to 6As shown, the movable element 200 further comprises a first rotating element 220 rotatably sleeved outside the sliding element 210, the temple connecting structure further comprises a second rotating element 500 spaced apart from the first rotating element 220 and rotatably connected to the mounting element 100, both ends of the first elastic element 410 are connected to the first rotating element 220 and the second rotating element 500 respectively, and the axial direction of the first elastic element 410 is parallel to the distribution direction of the first rotating element 220 and the second rotating element 500. The mounting element 100 is fixedly provided with a connecting shaft 460, and the second rotating element 500 is rotatably sleeved on the connecting shaft 460. The sliding element 210 will drive the first rotating element 220 to slide synchronously, so that the distance between the first rotating element 220 and the second rotating element 500 changes, that is, the deformation amount of the first elastic element 410 changes. Under the action of the elastic force of the first elastic element 410, the first rotating element 220 and the second rotating element 500 will rotate, so that the connection positions of the first elastic element 410 and the first rotating element 220 and the second rotating element 500 are located on the opposite sides of the first rotating element 220 and the second rotating element 500, and the first rotating element 220 and the second rotating element 500 are distributed along the axial direction of the first elastic element 410, that is, the direction of the elastic force of the first elastic element 410 changes. In addition, the two ends of the first elastic element 410 can be supported by the first rotating element 220 and the second rotating element 500 respectively, so that the first elastic element 410 cannot be dislocated in the mounting element 100, and the first rotating element 220 can be stably supported by the elastic force, thereby ensuring the stability of the clamping force of the temple 20, so that the user can stably wear the head-mounted display device. Of course, in other embodiments, one end of the first elastic element 410 can be embedded on the mounting element 100, and the other end can be rotatably sleeved on the first rotating element 220.

[0079] Specifically, the head-mounted display device has a wearing side P, and the first elastic element 410 is provided as a compression spring. When the connecting element 300 is turned outward at a larger angle from the open position, the sliding element 210 gradually approaches the wearing side P and gradually approaches the second rotating element 500.

[0080] That is, the arc-shaped wall 102 is convexly arranged in an arc shape toward the first elastic element 410, and in the direction toward the wearing side P, the distance between the arc-shaped wall 102 and the second rotating element 500 gradually decreases. When the connecting element 300 is just in the open position, the initial position of the sliding element 210 corresponds to the end far away from the second rotating element 500.

[0081] It can be understood that when the temple 20 is turned outward, the sliding element 210 is subjected to the elastic force F of the first elastic element 410 kThe tangential force of the arc-shaped wall 102 at the current position of the sliding member 210 acts on the pushing arm 310, that is, the included angle θ is the included angle between the axial direction of the first elastic member 410 and the tangential direction of the arc-shaped wall 102 at the current position of the sliding member 210.

[0082] In the embodiment, when the angle of the outward turning of the connecting member 300 increases, the sliding member 210 will rotate towards the wearing side P, the distance between the first rotating member 220 and the second rotating member 500 thus decreases, so that the compression amount of the first elastic member 410 increases, that is, F k increases, and the included angle θ increases, and cos θ decreases, and the increase of F k and the decrease of cos θ can offset each other, so that the value of the elastic force F N experienced by the pushing member 310 changes little or even remains almost unchanged, which is beneficial to keeping the clamping force generated by the first elastic member 410 on the temple 20 constant.

[0083] Further, referring to Figure 7 in the embodiment, a is defined as the center distance of the first rotating member 220 and the second rotating member 500 at the initial position, b is defined as the center distance of the first rotating member 220 and the second rotating member 500 at any position, r is defined as the rotating radius of the sliding member 210, x0 is defined as the original length of the first elastic member 410, and θ is defined as the included angle between the axial direction of the first elastic member 410 and the tangential direction of the arc-shaped wall 102, and the above parameters satisfy:

[0084]

[0085] It can be understood that when the first rotating member 220 is at the initial position, that is, when the connecting member 300 is at the open position, the elastic force experienced by the pushing arm from the sliding member satisfies:

[0086] F N1 =F k1 cos θ1=k(x0-a)cos θ1; ②

[0087] When the first rotating member 220 is at any position, the elastic force experienced by the pushing arm 310 from the sliding member 210 satisfies:

[0088] F N2 =F k2 cos θ2=k(x0-b)cos θ2; ③

[0089] The axial center of the first rotating member 220 at the initial position is defined as O1, the axial center at any position is defined as O2, the axial center of the second rotating member 500 is defined as A, the axial center of the arc-shaped wall 102 is defined as B, and the triangles △AO1B and △AO2B have the same side L AB , that is:

[0090]

[0091] Substituting the cosine formula of triangle, that is, there is:

[0092] a 2 + r 2 -2ar cos (90°+θ1)=b 2 + r 2 -2br cos (90°+θ2)

[0093] Therefore, it can be obtained that:

[0094] a 2 -b 2 +2ar sinθ1=2br sinθ2 ④

[0095] Based on formula ④, then:

[0096]

[0097] Substituting formula ⑤ into formula ②, then:

[0098]

[0099] Substituting formula ① into formula ⑥, then:

[0100]

[0101] Therefore, in the embodiment, when the first rotating member 220 is at any position, the elastic force F N2 experienced by the pushing arm 310 from the sliding member 210 is equal to the elastic force F N1 experienced by the pushing arm 310 from the sliding member 210 when the first rotating member 220 is at the initial position, that is, the elastic force F N remains unchanged, and thus the clamping force F x can also remain unchanged. In this way, when users with different head circumferences wear the head-mounted display device, the clamping force experienced by the users can be relatively constant even if the angles of the eyeglasses 20 outturned are different, and thus the fitting degree of the head-mounted display device is better, which is conducive to improving the wearing comfort of the users.

[0102] Further, in the embodiment, as Figure 2As shown, the first rotating member 220 and the second rotating member 500 are provided with a sleeve joint shaft 430, and the sleeve joint shaft 430 of the first rotating member 220 and the sleeve joint shaft 430 of the second rotating member 500 are connected by means of insertion or universal joint or key groove cooperation, and the elastic member is sleeved outside the sleeve joint shaft 430 of the first rotating member 220 and the second rotating member 500. In this way, the first elastic member 410 can be guided to deform axially by the sleeve joint shaft 430, and the radial deformation is limited, so that the first rotating member 220 can be subjected to stable elastic force, thereby ensuring the stability of the clamping force of the glasses leg 20, and in addition, the installation stability of the first elastic member 410 can also be ensured. Of course, in other embodiments, the two ends of the first elastic member 410 can be fixedly connected to the first rotating member 220 and the second rotating member 500, respectively.

[0103] In an embodiment, as shown in the drawings, Figure 2 The first rotating member 220 includes a support portion 221 and two sleeve ring portions 222, and the two sleeve ring portions 222 are distributed in an axial direction. The sliding member 210 is provided with two clamping members 450, the clamping members 450 are located between the two sleeve ring portions 222, and one clamping member 450 corresponds to one sleeve ring portion 222. The clamping member 450 can be a clamp, a spring, etc. The sliding member 210 is provided with a clamping groove corresponding to the clamping member 450, and the clamping member 450 is clamped in the clamping groove, so that the clamping member 450 can be relatively fixedly clamped on the sliding member 210, and one sleeve ring portion 222 of the first rotating member 220 will be correspondingly clamped between a wall body of the mounting member 100 and one clamping member 450. In this way, the first rotating member 220 and the sliding member 210 can be relatively fixed in the axial direction with the mounting member 100, so that the sliding member 210 and the first rotating member 220 can be stably mounted on the mounting member 100.

[0104] Optionally, the first rotating member 220 and the second rotating member 500 are provided with a plurality of sleeve joint shafts 430 one by one, and the first elastic member 410 is correspondingly provided with a plurality of sleeve joint shafts 430. In actual application, the designer can select the number of sleeve joint shafts 430 on the first rotating member 220 and the second rotating member 500 according to the required clamping force requirement, and only one or a plurality of sleeve joint shafts 430 can be provided. In this embodiment, each rotating member is provided with two or more sleeve joint shafts 430, which can provide more first elastic members 410 and provide greater clamping force.

[0105] Optionally, the temple connecting structure further comprises at least one additional rotating member, the second rotating member 500 is connected to the additional rotating member in the same way as the first rotating member 220 is connected, and when the additional rotating member is provided in multiple, the multiple additional rotating members are connected in sequence in the same way as the first rotating member 220 and the second rotating member 500 are connected. In this way, multiple sets of connecting rod structures can be formed, and the elastic force between every two adjacent rotating members is added to form a resultant force, which acts on the connecting member 300 to provide additional inward clamping force for the temple 20. Of course, in other embodiments, the double connecting rod structure composed of the first rotating member 220 and the second rotating member 500 can also provide additional clamping force for the temple 20.

[0106] Optionally, the first rotating member 220, the second rotating member 500, and the sliding member 210 are provided in one-to-one correspondence. That is, the mounting member 100 is provided with multiple sets of combinations of the first rotating member 220, the second rotating member 500, and the sliding member 210, and the connecting member 300 can act on each combination of the sliding member 210 to drive the sliding member 210, the first rotating member 220, and the second rotating member 500 in the corresponding combination to move correspondingly. The resultant force of the multiple sliding members 210 acting on the connecting member 300 provides additional inward clamping force for the temple 20.

[0107] In an embodiment, as shown in Figures 2 to 6 The mounting member 100 is fixedly provided with a fixed shaft 440, the fixed shaft 440 is arranged in parallel with and spaced apart from the sliding member 210, the connecting member 300 is provided with a pushing arm 310 extending towards the sliding member 210, the pushing arm 310 is rotatably sleeved outside the fixed shaft 440, the head-mounted display device has a wearing side P, the pushing arm 310 is located at least partially on the side of the sliding member 210 away from the wearing side P, and the pushing arm 310 abuts against the sliding member 210 when the connecting member 300 is in the unfolded position. It can be understood that the wearing side P is the side of the head-mounted display device opposite to the human skin when the head-mounted display device is worn by the user. When the connecting member 300 is folded from the unfolded position, the pushing arm 310 swings towards the back side of the wearing side P, and the pushing arm 310 can be separated from the sliding member 210; and when the connecting member 300 is unfolded from the unfolded position, the pushing arm 310 swings towards the wearing side P, and the pushing arm 310 can push the sliding member 210 to drive the sliding member 210 to slide in the sliding groove 101. Of course, in other embodiments, the connecting member 300 can drive the sliding member 210 to slide through a connecting rod mechanism, and in the process of rotating the connecting member 300 from the folded position to the unfolded position, the connecting member 300 drives the connecting rod to be straightened, and only when the connecting member 300 continues to unfold, the driving force of the connecting member 300 can drive the sliding member 210 to slide through the straightened connecting rod mechanism.

[0108] Further, in the present embodiment, as shown in Figures 2 to 6 the outer periphery contour of the sliding member 210 is circular, and the pushing arm 310 is provided with an arc-shaped slot 311 on the side close to the wearing side P, corresponding to the sliding member 210, and the pushing arm 310 pushes the sliding member 210 at the position of the arc-shaped slot 311. In this way, after the pushing arm 310 abuts against the sliding member 210, the sliding member 210 can be engaged in the arc-shaped slot 311, and the sliding member 210 can rotate circumferentially in the arc-shaped slot 311, so that the pushing arm 310 can stably and reliably push the sliding member 210. Without loss of generality, the center of the arc-shaped wall 102 is located on the rotation axis of the connecting member 300, that is, the rotation axis of the connecting member 300 is also the rotation axis of the sliding member 210, so that when the pushing arm 310 pushes the sliding member 210 to slide, the sliding member 210 can be stably engaged in the arc-shaped slot 311. Of course, in other embodiments, the side of the pushing arm 310 that pushes the sliding member 210 can also be linear, and the sliding member 210 slides in the sliding slot 101 while also sliding relative to the pushing arm 310.

[0109] In an embodiment, as shown in Figure 11 and Figure 12 a wire passing space 103 is formed in the mounting member 100, the wire passing space 103 is used for the heat dissipation member 600 and / or the electrical connecting member 300 to pass through, the connecting member 300 is arranged outside the mounting member 100, and the end of the sliding member 210 protrudes outside the mounting member 100 to be acted on by the pushing arm 310. Among them, the heat dissipation member 600 can be a graphite sheet or a metal sheet, and the electrical connecting member 300 can be a FPC (Flexible Printed Circuit) or a wire. In the present embodiment, the connecting member 300 is connected to the mounting member 100 outside the mounting member 100, and when the connecting member 300 rotates, it will not interfere with the components in the wire passing space 103, which is beneficial to guarantee the installation stability of the heat dissipation member 600 and the electrical connecting member 300. Of course, in other embodiments, the connecting member 300 can be arranged inside the mounting member 100 and a corresponding avoiding slot can be provided.

[0110] Further, in the present embodiment, please refer to Figure 1 and Figure 2The mirror leg connecting structure further comprises two fixing shafts 440, and the two fixing shafts 440 are respectively fixed to the opposite two side walls of the mounting piece 100. The connecting piece 300 comprises a connecting portion 320 and two push arms 310 connected to the two ends of the connecting portion 320 respectively, and one push arm 310 is rotatably sleeved outside one fixing shaft 440. In this way, the fixing shaft 440 does not occupy the wire space 103, and a large enough space is provided for the electric connecting piece 300 and the heat dissipation piece 600. When the electric connecting piece 300 and the heat dissipation piece 600 are bent, they will not be interfered by the fixing shaft 440, the wear of the electric connecting piece 300 and the heat dissipation piece 600 is reduced, and the service life of the electric connecting piece 300 and the heat dissipation piece 600 is guaranteed. Of course, in other embodiments, one fixing shaft 440 can be connected to the opposite two side walls of the mounting piece 100, and the electric connecting piece 300 and the heat dissipation piece 600 are distributed on the two sides of the fixing shaft 440.

[0111] Further, in the embodiment, as shown in Figure 2 the end of the fixing shaft 440 is provided with a shaft protrusion 441, and the push arm 310 is clamped between the shaft protrusion 441 and the wall of the mounting piece 100. In this way, the push arm 310 can be stably connected with the mounting piece 100 and the fixing shaft 440, and the push arm 310 is abutted on the mounting piece 100 through the shaft protrusion 441, so as to realize the damping rotation between the connecting piece 300 and the fixing shaft 440, so that the mirror leg 20 cannot be easily opened and closed. Further, by adjusting the distance between the shaft protrusion 441 and the mounting piece 100, the pressing force of the shaft protrusion 441 on the push arm 310 is adjusted, so as to adjust the damping force between the push arm 310 and the mounting piece 100. Of course, in other embodiments, the push arm 310 and the mounting piece 100 can be connected through a spring, so as to limit the self-opening and closing of the mirror leg 20.

[0112] Further, in the embodiment, as shown in Figure 1 and Figure 12As shown, the mounting member 100 is provided with an abutting protrusion 121 in the wall of the wearing side P, the abutting protrusion 121 is arranged close to the connecting member 300, and the outer surface of the abutting protrusion 121 is arranged as a curved surface, so as to abut against the electric connecting member 300 and / or the heat dissipation member 600 when the connecting member 300 is in the folded position. It can be understood that the outer surface of the abutting protrusion 121 is arranged as a relatively smooth curved surface, so that when the electric connecting member 300 or the heat dissipation member 600 abuts against, no obvious creases are generated, and the force of the abutting protrusion 121 on the electric connecting member 300 or the heat dissipation member 600 is dispersed relatively uniformly, so that stress concentration does not occur, and damage to the electric connecting member 300 or the heat dissipation member 600 can be avoided. Further, the corresponding position of the heat dissipation member 600 or the electric connecting member 300 can also be pre-pressed into a shape that is adapted to the abutting protrusion 121, so that when the heat dissipation member 600 or the electric connecting member 300 is folded, the shape is adaptively fitted on the abutting protrusion 121, so that the heat dissipation member 600 or the electric connecting member 300 is forced to fold at the rotating node is avoided to the greatest extent, which is beneficial to reduce wear and tear and protect the structural stability of the heat dissipation member 600 or the electric connecting member 300. Of course, in other embodiments, a buffer cotton or the like can also be arranged at the position of the abutting protrusion 121, so as to buffer the force of the mounting member 100 on the heat dissipation member 600 or the electric connecting member 300.

[0113] In an embodiment, as Figures 8 to 10As shown, the second elastic member 420 is connected between the push arm 310 and the fixed shaft 440, and is configured to be axially telescopic. The second elastic member 420 is connected to a first position E of the fixed shaft 440, which is offset from the axis of the fixed shaft 440. During the switching of the connector 300 from the folded position to the unfolded position, the elastic deformation of the second elastic member 420 first increases and then decreases. Since the connection position of the second elastic member 420 on the fixed shaft 440 is offset from the axis of the fixed shaft 440, the rotation of the connector 300 around the fixed shaft 440 will cause the axial length of the second elastic member 420 to change, and the elastic deformation of the second elastic member 420 will also change accordingly, thereby causing the elastic force of the second elastic member 420 acting on the connector 300 to change. During the switching of the connector 300 from the folded position to the unfolded position, the elastic force acting on the connector 300 first increases and then decreases. That is, at an intermediate position between the folded position and the unfolded position (for the convenience of subsequent description, it is referred to as the maximum elastic position), the elastic force acting on the connector 300 is the largest, and the elastic force acting on the connector 300 at the folded position or the unfolded position is smaller than the elastic force at the intermediate position. In this way, under the action of the second elastic member 420, when the temple 20 does not receive an external force in the folded state or the unfolded state, it can maintain its current state and avoid the self-opening and closing of the temple 20. Moreover, when the elastic deformation of the second elastic member 420 reaches the maximum position, if the temple 20 has an initial speed in the direction of folding or unfolding, under the action of the second elastic member 420, the temple 20 can subsequently be folded or unfolded without receiving a force, that is, the elastic bow effect can be achieved, thereby improving the operation convenience of unfolding or folding the temple 20.

[0114] Further, in the embodiment, the second elastic member 420 is connected to a second position F of the pushing arm 310, the first position E is closer to the wearing side P than the axis of the fixed shaft 440, and the second position F is farther away from the wearing side P than the axis of the fixed shaft 440; the rotating shaft has a first radial line D passing through the first position E, and the second elastic member 420 is in a natural state and located on opposite sides of the first radial line D when the pushing arm 310 is in the folded position and the unfolded position, respectively. Specifically, when the connecting member 300 is in the folded position, the second elastic member 420 is in the original length and located on one side of the first radial line D; when the connecting member 300 rotates from the folded position to the unfolded position, the second elastic member 420 approaches the first radial line D, in the process, the second elastic member 420 is stretched, and the elastic deformation gradually increases until the axis of the second elastic member 420 coincides with the first radial line D, at this time, the second elastic member 420 is stretched to the maximum length, and the connecting member 300 is in the maximum elastic position; when the connecting member 300 continues to rotate from the maximum elastic position to the unfolded position, the second elastic member 420 moves to the other side of the first radial line D, in the process, the second elastic member 420 starts to retract, and the elastic deformation gradually decreases until it returns to the original length, and the connecting member 300 moves to the unfolded position. That is, in the process of switching the connecting member 300 from the folded position to the unfolded position, the second elastic member 420 is first stretched and then retracted. Without loss of generality, when the connecting member 300 is in the unfolded position and the folded position, the second elastic member 420 is symmetrical to the first radial line D, and the maximum elastic position is the end point between the unfolded position and the folded position, at this time, the opening angle of the temple 20 relative to the temple 20 is about 45 degrees, so that the user can provide a better hand feeling.

[0115] The application also provides a head-mounted display device, which comprises a frame 10, a temple 20, and a temple connecting structure. The specific structure of the temple connecting structure is described in the above embodiments. Since the head-mounted display device adopts all the technical solutions of the above embodiments, it has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0116] In an embodiment, as Figures 13 to 16As shown, the temple 20 is provided with a receiving groove 23, which is a blind groove penetrating the end face of the temple 20 and the wearing side P, has a first opening 24 located at the end face of the temple 20 and a second opening 25 located at the wearing side P of the temple 20; the mounting piece 100 is inserted into the receiving groove 23, and the mounting piece 100 has opposite first and second side walls 110 and 120, the second side wall 120 is located at the wearing side P of the head-mounted display device, and the first side wall 110 is exposed to the first opening 24 when the temple 20 is folded, and the second side wall 120 is exposed to the second opening 25 when the temple 20 is opened. It can be understood that the receiving groove 23 is arranged at one end of the temple 20 connected with the connecting piece 300, which plays a certain accommodation role for the mounting piece 100. When the temple 20 is in an open state, the first side wall 110 is covered on the back side of the wearing side P by the temple 20, which is beneficial to ensure the appearance aesthetics of the head-mounted display device in use. In this way, the appearance aesthetics of the head-mounted display device can be improved, and at the same time, when the temple 20 rotates, the mounting piece 100 is avoided by the first and second openings 24 and 25 to avoid interference between the temple 20 and the mounting piece 100.

[0117] Further, the first side wall 110 is conformally arranged with the end face of the temple 20, and the second side wall 120 is conformally arranged with the wearing side P of the temple 20. In this way, when the temple 20 is in a folded state, the first opening 24 is covered by the first side wall 110, and the shape of the first side wall 110 and the end face of the temple 20 is matched, which is beneficial to ensure the appearance aesthetics of the head-mounted display device when it is stored; when the temple 20 is in an open state, the second opening 25 and the second side wall 120 are located at the wearing side P, and the shape of the second side wall 120 and the surface of the wearing side P of the temple 20 is matched, which will not hurt the user's skin, and is beneficial to ensure the wearing comfort of the user.

[0118] In an embodiment, there is a cooperation gap between the temple 20 and the mounting piece 100, and the head-mounted display device further comprises a waterproof piece for blocking external moisture from entering the frame 10 or the temple 20 from the cooperation gap. In this way, the cooperation gap between the temple 20 and the mounting piece 100 makes the temple 20 not interfere with the mounting piece 100 when the connecting piece 300 rotates relative to the mounting piece 100, and the waterproof piece can block the external moisture from entering the cooperation gap or can block the water entering the cooperation gap from spreading into the frame 10 or the temple 20, so as to protect the electronic components in the temple 20 and the frame 10. Of course, in other embodiments, the temple 20 and the mounting piece 100 can be connected through a stretchable wrinkle part to avoid forming a cooperation gap, and the wrinkle part is folded or unfolded to avoid interference when the temple 20 rotates relative to the mounting piece 100.

[0119] In an embodiment, as shown in Figure 12 The waterproof member includes a first waterproof member 710 and a second waterproof member 720. The first waterproof member 710 is arranged in the temple 20 and is arranged close to the port of the mounting member 100 relative to the temple 20. The outer periphery of the first waterproof member 710 is sealingly fitted to the inner periphery of the temple 20. The second waterproof member 720 is arranged in the frame 10 and is arranged close to the port of the mounting member 100 relative to the frame 10. The outer periphery of the second waterproof member 720 is sealingly fitted to the inner periphery of the frame 10. It can be understood that the first waterproof member 710 and the second waterproof member 720 are both provided with structures through which the electrical connecting member 300 can pass. In this way, when external moisture enters from the fitting gap between the temple 20 and the mounting member 100, the external moisture cannot continue to enter the internal space of the temple 20 under the blocking of the first waterproof member 710, which is conducive to ensuring the working stability of the electronic components in the temple 20. The external moisture that enters the wire passing space 103 cannot continue to spread to the internal space of the frame 10 under the blocking of the second waterproof member 720, which is conducive to ensuring the working stability of the electronic components in the frame 10. As for the electrical connecting member 300 in the wire passing space 103, if the electrical connecting member 300 is arranged as a wire, the moisture cannot affect the performance of the wire. If the electrical connecting member 300 is arranged as an FPC, a waterproof film can be coated on the surface of the FPC to avoid water entering and affecting the performance of the FPC.

[0120] In an embodiment, as shown in Figure 11As shown, the first waterproof member 710 and the second waterproof member 720 are arranged at the end of the temple 20 close to the mounting member 100, the temple 20 has opposite first and second shell portions 21 and 22, the second shell portion 22 is located at the wearing side P of the head-mounted display device, the first waterproof member 710 is fixedly arranged at the inner side of the first shell portion 21 and sealingly cooperates with the first side wall 110, and the second waterproof member 720 is fixedly arranged at the end surface of the second shell portion 22 and sealingly cooperates with the second side wall 120. It can be understood that, in order to avoid interference between the temple 20 and the mounting member 100, there is a cooperation gap between the first shell portion 21 and the first side wall 110, and there is also a cooperation gap between the second shell portion 22 and the second side wall 120, in this embodiment, the first and second waterproof members 710 and 720 respectively seal the two cooperation gaps. Specifically, when the temple 20 is in the open state, the outer side (i.e., the side away from the cable space 103) of the first waterproof member 710 and the first side wall 110 sealingly cooperates, and the end surface of the second waterproof member 720 and the second side wall 120 sealingly cooperates; when the temple 20 is in the folded state, the end surface of the first waterproof member 710 and the first side wall 110 sealingly cooperates, and the outer side surface of the second waterproof member 720 and the first side wall 110 sealingly cooperates. The first and second waterproof members 710 and 720 are both configured of soft plastic or soft rubber material, and when the temple 20 rotates relative to the mounting member 100, it will not be strongly interfered by the first and second waterproof members 710 and 720.

[0121] The above description is only optional embodiments of the present application, and does not limit the patent scope of the present application, any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
