[0049] The present application provides a temple connecting structure.

[0050] 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, which comprises 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:

[0051] A mounting member 100 fixedly connected to the frame 10;

[0052] A first elastic member 410 mounted on the mounting member 100, the first elastic member 410 being configured in an axial deformation state; and

[0053] A connecting member 300 fixedly connected to the temple 20 and rotatably connected to the mounting member 100, and the rotation axis of the connecting member 300 intersects the axial direction of the first elastic member 410;

[0054] The elastic force of the first elastic member 410 can act on the connecting member 300, thereby providing a clamping force for the temple 20, and when the connecting member 300 is everted from the open position, the elastic deformation amount of the first elastic member 410 and the angle between the axial direction of the first elastic member 410 and the mounting member can be changed, so that the amplitude fluctuation of the clamping force is kept within a preset percentage.

[0055] 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 folding 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 opening 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 opening state, and the connecting piece 300 will also be folded outward correspondingly. At this time, the elastic force of the first elastic piece 410 can react on the connecting piece, thereby providing a clamping force for the temple. Since the axial direction of the first elastic piece 410 intersects the rotation axis of the connecting piece 300, which is also the rotation axis of the temple 20, the elastic force of the first elastic piece 410 has a component in the folding direction of the temple 20, so that the first elastic piece 410 can provide an 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. Moreover, during the folding process of the connecting piece 300, the elastic deformation amount of the first elastic piece 410 and the angle between the axial direction of the first elastic piece 410 and the mounting piece 100 are changed, so that the size and direction of the elastic force of the first elastic piece 410 can be changed at the same time. Therefore, the change in the size of the elastic force of the first elastic piece 410 can be offset by the change in the direction of the elastic force of the first elastic piece 410, so that the amplitude fluctuation of the clamping force provided by the first elastic piece 410 for the temple 20 is kept within a preset percentage, and the user with different head circumferences can feel comfortable clamping force, which is beneficial to improve the wearing comfort of the head-mounted display device.

[0056] In an embodiment, the temple connecting structure further comprises a first rotating piece 220, and the elastic piece 410 is connected to the first rotating piece 220, and a first axis is defined outside the first rotating piece 220 and intersects the axial direction of the elastic piece 410. The connecting piece 300 can drive the first rotating piece 220 to rotate around the first axis, so as to drive the elastic piece 410 to move, thereby changing the elastic deformation amount of the elastic piece 410 and the angle between the axial direction of the elastic piece 410 and the mounting piece 100. Since the first axis intersects the axial direction of the first elastic piece 410, when the first rotating piece 220 rotates around the first axis to drive the first elastic piece 410 to move, the axial direction and the elastic deformation amount of the first elastic piece 410 will change, thereby changing the direction and size of the elastic force of the first elastic piece 410. Of course, in other embodiments, the connecting piece 300 can drive the first rotating piece 220 to slide along a straight line trajectory intersecting the axial direction of the first elastic piece 410.

[0057] Further, in the embodiment, as shown in FIG. 1, Figures 2 to 6As shown, the temple connecting structure further comprises a sliding member 210 and a second rotating member 500, the first rotating member 220 is rotatably sleeved outside the sliding member 210, when the connecting member 300 is turned outwards from the open position, the sliding member 210 can be driven to rotate around the first axis, so as to drive the first rotating member 220 to rotate around the first axis; the second rotating member 500 is arranged in a spaced manner with the first rotating member 220 and is rotatably connected to the mounting member 100, two ends of the first elastic member 410 are respectively connected to the first rotating member 220 and the second rotating member 500, and the axial direction of the first elastic member 410 is parallel to the distribution direction of the first rotating member 220 and the second rotating member 500. Wherein, the mounting member 100 is fixedly provided with a connecting shaft 460, and the second rotating member 500 is rotatably sleeved on the connecting shaft 460. The sliding member 210 will drive the first rotating member 220 to slide synchronously, so that the distance between the first rotating member 220 and the second rotating member 500 changes, that is, the deformation amount of the first elastic member 410 changes, under the elastic force of the first elastic member 410, the first rotating member 220 and the second rotating member 500 will rotate, so that the connection positions of the first elastic member 410, the first rotating member 220 and the second rotating member 500 are located on the opposite sides of the first rotating member 220 and the second rotating member 500, and the first rotating member 220 and the second rotating member 500 are distributed along the axial direction of the first elastic member 410, that is, the direction of the elastic force of the first elastic member 410 changes. In addition, the two ends of the first elastic member 410 can be respectively supported by the first rotating member 220 and the second rotating member 500, so that the first elastic member 410 cannot be dislocated in the mounting member 100, and the first rotating member 220 can be stably elastically forced, so as to ensure 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 member 410 can be embedded on the mounting member 100, and the other end can be rotatably sleeved on the first rotating member 220.

[0058] In an embodiment, the head-mounted display device has a wearing side P, the connecting member 300 is provided with a pushing arm 310, when the connecting member 300 is turned outwards from the open position, the pushing arm 310 pushes the sliding member 210; the sliding member 210 is located between the first axis and the second rotating member 500, the first elastic member 410 is arranged as a compression spring, when the angle of the connecting member 300 turned outwards from the open position becomes larger, the sliding member 210 gradually approaches the wearing side and gradually approaches the second rotating member 500.

[0059] Thus, the rotation trajectory of the slider 210 is an arc protruding towards the first elastic member 410, and in the direction towards the wearing side P, the distance between the rotation trajectory of the slider 210 and the second rotating member 500 gradually decreases. When the connector 300 is just in the open position, the initial position of the slider 210 is located at the end away from the second rotating member 500.

[0060] It is understandable that when the temple 20 is folded outward, the sliding member 210 is subjected to the elastic force F of the first elastic member 410. k The tangential component of the force along its rotational trajectory will act on the push arm 310, and this component is the elastic force F from the sliding member 210 acting on the push arm 310. N That is, F N =F k cosθ, where θ is the angle between the axial direction of the first elastic element 410 and the tangential direction of the rotation trajectory of the slider 210 at the current position of the slider 210.

[0061] In this embodiment, when the outward angle of the connector 300 increases, the slider 210 will rotate towards the wearing side P, thereby reducing the distance between the first rotating member 220 and the second rotating member 500, which increases the compression of the first elastic member 410, i.e., F. k As F increases, the included angle θ will increase, and cosθ will decrease. k The increase in magnitude and the decrease in cosθ can offset each other, thus reducing the elastic force F on the resisting member 310. N The value changes very little, or even remains almost unchanged, which helps to keep the magnitude of the clamping force generated by the temple 20 under the action of the first elastic element 410 constant.

[0062] Furthermore, in this embodiment, please refer to Figure 5 and Figure 6 The first end of the push arm 310 is used to push against the sliding member 210, and the second end of the push arm 310 is used to be fixedly connected to the temple 20. The push arm 310 is rotatably connected to the mounting member 100 between its two ends. Thus, the temple 20 and the push arm 310 form a lever at the rotatable connection point between the push arm 310 and the mounting member 100. According to the lever principle, the clamping force F... x Size and elasticity F N The sizes satisfy the following:

[0063] F x *x2=F N *x1

[0064] x2 is the distance from the point where the user's head contacts the temple 20 to the axis of rotation of the connector 300. The change in x2 is negligible; therefore, under the elastic force F... N When the clamping force F remains constantx The size can also remain unchanged. In the technical solution of this invention, the magnitude of the clamping force generated by the temple 20 under the action of the first elastic member 410 can tend to be constant as the outward angle of the temple 20 changes. When users with different head circumferences wear the head-mounted display device, even if the outward angle of the temple 20 is different, they can still be subjected to a relatively constant clamping force. In this way, the fit of the head-mounted display device is better, which is conducive to improving the user's wearing comfort.

[0065] It is understood that in this embodiment, the lever structure ensures that even if the elastic force F... N The direction changes, but as long as the elastic force F N The magnitude remains unchanged, and the clamping force F x The size also remains unchanged. Of course, in other embodiments, the aforementioned function can also be achieved by a fixed pulley mechanism. Specifically, a fixed pulley can be set at the pivot point of the connector, and the sliding member and the connector are connected by a non-elastic traction rope. The traction rope is wrapped around one side of the fixed pulley, wherein the connector is connected to the traction rope at the end near the temple. In this way, when the magnitude of the force exerted by the sliding member on one end of the traction rope remains unchanged, the tension of the other end of the traction rope on the connector can also provide a relatively stable clamping force for the temple.

[0066] Further, please refer to Figure 7 In this embodiment, 'a' is defined as the center distance between the first rotating member 220 and the second rotating member 500 at their initial positions, 'b' is the center distance between the first rotating member 220 and the second rotating member 500 at any position, 'r' is the rotation radius of the sliding member 210, 'x0' is the original length of the first elastic member 410, and 'θ' is the angle between the axial direction of the first elastic member 410 and the tangent of the rotation trajectory of the sliding member 210. The above parameters satisfy:

[0067]

[0068] It can be understood that when the first rotating member 220 is in the initial position, that is, when the connecting member 300 is in the open position, the elastic force from the sliding member on the pushing arm 310 satisfies:

[0069] F N1 =F k1 cosθ1=k(x0-a)cosθ1; ②

[0070] When the first rotating member 220 is in any position, the elastic force from the sliding member 210 on the pushing arm 310 satisfies:

[0071] F N2 =F k2 cosθ² = k(x₀ - b)cosθ²; ③

[0072] The axis center of the first rotating member 220 in the initial position is defined as O1, the axis center in any position is defined as O2, the axis center of the second rotating member 500 is defined as A, the projection point of the rotating axis of the sliding member 210 is defined as B, and ΔAO1B and ΔAO2B have the same side L AB That is, there is:

[0073]

[0074] Substituting the cosine formula of the triangle, that is, there is:

[0075] a 2 +r 2 -2arcos(90°+θ1)=b 2 +r 2 -2brcos(90°+θ2)

[0076] Therefore, it can be obtained that:

[0077] a 2 -b 2 +2arsinθ1=2brsinθ2 ④

[0078] Based on formula ④, it can be obtained that:

[0079]

[0080] Substituting formula ⑤ into formula ②, it can be obtained that:

[0081]

[0082] Substituting formula ① into formula ⑥, it can be obtained that:

[0083]

[0084] Therefore, in the embodiment, when the first rotating member 220 is in any position, the elastic force F N2 experienced by the push arm 310 from the sliding member 210 is equal to the elastic force F N1 experienced by the push arm 310 from the sliding member 210 when the first rotating member 220 is in the initial position, that is, the elastic force F N remains unchanged, and thus the clamping force Fx 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 is relatively constant even if the angles of the eyeglasses 20 are different, and thus the adaptability of the head-mounted display device is better, which is beneficial to improving the wearing comfort of the users.

[0085] Further, in the embodiment, the mounting member 100 is provided with a sliding groove 101, the sliding groove 101 is provided with an arc-shaped wall 102, the first axis is the axis of the arc-shaped wall 102, the sliding member 210 is inserted into the sliding groove 101 and can slide along the arc-shaped wall 102. In this way, the sliding member 210 can be guided to slide along the arc-shaped wall 102 by the arc-shaped wall 102, the rotation track of the sliding member 210 is the arc of the arc-shaped wall 102, and the axis of the arc-shaped wall 102 is the first axis. Of course, in other embodiments, the sliding groove 101 can not be provided, and the connecting member 300 is engaged with the sliding member 210 on the side farther away from the temple 20 along the rotation axis of the connecting member 300, so as to limit the movement track of the sliding member 210 driven by the connecting member 300, and the mounting member 100 is provided with a avoiding slot corresponding to the movement track of the sliding member 210.

[0086] Further, in the embodiment, as shown in Figure 8 the connecting member 300 includes a pushing arm 310, the head-mounted display device has a wearing side P, the pushing arm 310 is arranged on the side of the sliding member 210 away from the wearing side P, and when the connecting member 300 is folded out from the open position, the pushing arm 310 can push the sliding member 210 to slide, and when the connecting member 300 is folded in from the open position, the pushing arm 310 can be separated from the sliding member 210. 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. That is, when the connecting member 300 is in the folded position, the connecting member 300 and the sliding member 210 do not contact each other, until the connecting member 300 is rotated to the open position, the connecting member 300 abuts against the sliding member 210 through the pushing arm 310, and when the connecting member 300 is folded out from the open position, the connecting member 300 pushes the sliding member 210 to slide in the sliding groove 101 through the pushing arm 310. In this way, when the connecting member 300 is between the folded position and the open position, the connecting member 300 will not be subjected to the clamping force provided by the first elastic member 410, and the first elastic member 410 will not interfere with the switching of the temple 20 between the folded state and the open state. Of course, in other embodiments, the connecting member 300 can drive the sliding member 210 to slide through a connecting rod mechanism, and during the process that the connecting member 300 is rotated from the folded position to the open position, the connecting member 300 drives the connecting rod to be straightened, and when the connecting member 300 continues to be folded out, the force of the connecting member 300 can drive the sliding member 210 to slide through the straightened connecting rod mechanism.

[0087] Further, in the embodiment, the first rotating member 220 and the second rotating member 500 are provided with the sleeve shafts 430, and the sleeve shafts 430 of the first rotating member 220 and the second rotating member 500 are connected by means of insertion or universal joint or key groove matching, and the elastic member is sleeved outside the sleeve shafts 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 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 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.

[0088] In an embodiment, as shown in 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., and 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 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 respect to 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.

[0089] Optionally, the first rotating member 220 and the second rotating member 500 are provided with a plurality of sleeve shafts 430 one by one, and the first elastic member 410 is correspondingly provided with a plurality of sleeve shafts 430. In actual application, the designer can select the number of sleeve shafts 430 on the first rotating member 220 and the second rotating member 500 according to the required clamping force, and only one sleeve shaft 430 can be provided, or a plurality of sleeve shafts 430 can be provided. In the embodiment, each rotating member is provided with two or more sleeve shafts 430, which can be sleeved with more first elastic members 410 to provide greater clamping force.

[0090] Optionally, the temple connecting structure further comprises at least one additional rotating member, the second rotating member 500 is connected to one of the additional rotating members in the same way as the first rotating member 220 is connected to the second rotating member 500, when there are multiple additional rotating members, the multiple additional rotating members are connected in the same way as the first rotating member 220 is connected to the second rotating member 500. 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.

[0091] Optionally, the first rotating member 220, the second rotating member 500 and the sliding member 210 are provided one by one. 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.

[0092] In an embodiment, as shown in FIG. 6, the first rotating member 220 is connected to the second rotating member 500 through a connecting member 300, and the connecting member 300 is connected to the sliding member 210. Figure 3 and Figure 4 and Figures 8 to 10As shown, the mounting member 100 is fixedly provided with a fixed shaft 440, the fixed shaft 440 is arranged in parallel and spaced apart with 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 at least partially located on a 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 inward 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 folded outward 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 be folded outward, the driving force of the connecting member 300 can drive the sliding member 210 to slide through the straightened connecting rod mechanism.

[0093] Further, in the embodiment, the outer periphery contour of the sliding member 210 is circular, the pushing arm 310 is provided with an arc-shaped groove 311 corresponding to the sliding member 210 on the side close to the wearing side P, and the pushing arm 310 pushes the sliding member 210 at the position of the arc-shaped groove 311. In this way, after the pushing arm 310 abuts against the sliding member 210, the sliding member 210 can be clamped in the arc-shaped groove 311, and the sliding member 210 can rotate circumferentially in the arc-shaped groove 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 the rotation axis of the sliding member 210, that is, the first axis, so that the sliding member 210 can be stably clamped in the arc-shaped groove 311 when the pushing arm 310 pushes the sliding member 210 to slide. Of course, in other embodiments, the side of the pushing arm 310 pushing the sliding member 210 can also be linear, and the sliding member 210 can also slide relative to the pushing arm 310 when sliding in the sliding groove 101.

[0094] In an embodiment, as shown in FIG. 6, the sliding member 210 is provided with a sliding groove 211, and the connecting member 300 is provided with a pushing arm 310, the pushing arm 310 is rotatably sleeved outside the fixed shaft 440, and the pushing arm 310 is arranged on the side of the sliding member 210 away from the wearing side P. When the connecting member 300 is unfolded, the pushing arm 310 abuts against the sliding member 210, and when the connecting member 300 is folded, the pushing arm 310 swings towards the wearing side P and separates from the sliding member 210. Figure 11 and Figure 12As shown, the mounting member 100 is formed with a wire passing space 103 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 is arranged outside the mounting member 100 for the pushing arm 310 to act on. 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 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 ensure 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 arranged.

[0095] Further, in the embodiment, the temple connecting structure further comprises two fixing shafts 440, the two fixing shafts 440 are respectively fixedly arranged on the opposite two side walls of the mounting member 100, the connecting member 300 comprises a connecting portion 320 and two pushing arms 310 respectively connected to the two ends of the connecting portion 320, and one pushing arm 310 is correspondingly rotatably sleeved outside one fixing shaft 440. In this way, the fixing shaft 440 does not occupy the wire passing space 103, and can provide a large enough space for the electrical connecting member 300 and the heat dissipation member 600, so that the electrical connecting member 300 and the heat dissipation member 600 will not be interfered when they are bent, which can reduce the wear of the electrical connecting member 300 and the heat dissipation member 600, and is beneficial to ensure the service life of the electrical connecting member 300 and the heat dissipation member 600. Of course, in other embodiments, one fixing shaft 440 can be connected to the opposite two side walls of the mounting member 100, and the electrical connecting member 300 and the heat dissipation member 600 can be arranged on the two sides of the fixing shaft 440.

[0096] Further, in the embodiment, please refer to Figures 1 to 4 , the end of the fixing shaft 440 is provided with a shaft protrusion 441, and the pushing arm 310 is clamped between the shaft protrusion 441 and the wall of the mounting member 100. In this way, the pushing arm 310 can be stably connected with the mounting member 100 and the fixing shaft 440, and the pushing arm 310 can be abutted on the mounting member 100 through the shaft protrusion 441, so as to realize the damping rotation between the connecting member 300 and the fixing shaft 440, so that the temple 20 cannot be easily opened and closed. Further, by adjusting the distance between the shaft protrusion 441 and the mounting member 100, the pressing force of the shaft protrusion 441 on the pushing arm 310 can be adjusted, so as to adjust the damping force between the pushing arm 310 and the mounting member 100. Of course, in other embodiments, the pushing arm 310 and the mounting member 100 can be connected through a spring to limit the self-opening and closing of the temple 20.

[0097] Further, in the present embodiment, as shown in Figure 11 and Figure 12 , 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 it, no obvious creases will be 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 will 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 will be adaptively fitted on the abutting protrusion 121, so that the heat dissipation member 600 or the electric connecting member 300 can be prevented from being forced to fold at the rotating node to the greatest extent, which is beneficial to reduce wear and tear and ensure 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.

[0098] In an embodiment, as shown in 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, in the folded state and the unfolded state, when the temple 20 is not subjected to an external force, 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 force, that is, the elastic bow effect can be achieved, thereby improving the operation convenience of unfolding or folding the temple 20.

[0099] 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.

[0100] 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.

[0101] 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 500, 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.

[0102] 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.

[0103] 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 500 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.

[0104] 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 500 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 will not 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; under the blocking of the second waterproof member 720, the external moisture entering the wire passing space 103 will not continue to spread to the internal space of the frame 10, which is conducive to ensuring the working stability of the electronic components in the frame 10, and 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 will not affect the performance of the wire, and if the electrical connecting member 300 is arranged as an FPC, a waterproof film can be coated on the surface thereof to avoid water entering and affecting its performance.

[0105] 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.

[0106] 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.
