Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, "and / or" or "and / or" appears throughout the text, which means that the three parallel schemes include A scheme, or B scheme, or A and B schemes are satisfied at the same time. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the scope of protection claimed by the present application.

[0047] The application provides a temple connecting structure. It can be understood that the temple connecting structure is suitable for connecting the frame and the temple of various glasses. The following embodiments take a head-mounted display device as an example, but the application of the temple connecting structure of the application is not limited to the head-mounted display device.

[0048] Referring to FIGS. 1-3, in an embodiment of the application, the temple connecting structure is used to connect the temple 20 and the frame 10, wherein the extension direction of the frame 10 is K, the extension direction of the temple 20 is T, and the temple connecting structure comprises:

[0049] a first support 100 and a second support 200 rotatably connected to each other, the first support 100 is used to fixedly connect the frame 10, and the second support 200 is used to fixedly connect the temple 20;

[0050] a movable part 300 movably mounted on the first support 100 and connected to the second support 200; and

[0051] a first elastic part 410 provided between the first support 100 and the movable part 300 and separably arranged with the movable part 300;

[0052] When the second support 200 is folded from the open position, the elastic part is separated from the movable part 300;

[0053] When the second support 200 is everted from the open position, the two ends of the first elastic part 410 abut against the movable part 300 and the first support 100 respectively, and the second support 200 can be subjected to the elastic force transmitted by the elastic part through the movable part 300, thereby providing clamping force for the temple 20.

[0054] It can be understood that the abutment of the first elastic part 410 to the movable part 300 and the first support 100 can be direct abutment, indirect abutment or embedded connection, so that the first elastic part 410 can transmit elastic force to the movable part 300 and the first support 100.

[0055] In the technical solution of the application, the second support 200 has a folded position and an open position, the temple 20 is fixedly connected to the second support 200, the temple 20 is in a folded state and overlapped with the frame 10 when the second support 200 is in the folded position, and the temple 20 is in an open state and the frame 10 and the temple 20 are substantially at 90 degrees when the second support 200 is in the open position.

[0056] When the user with a larger head circumference wears the head-mounted display device, the temple 20 will be folded outward compared to the unfolded state, and the second support 200 will also be folded outward from the unfolded position, thereby enabling the movable piece 300 to be subjected to the elastic force of the first elastic piece 410, and at the same time, the second support 200 acts on the movable piece 300, and the second support 200 can also be subjected to the elastic force of the first elastic piece 410 transmitted by the movable piece 300. In this way, 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 user's head and improving the wearing stability of the head-mounted display device.

[0057] Further, in the unfolded position, the first elastic piece 410 can be in a natural state, and when the second support 200 is folded outward from the unfolded position, the first elastic piece 410 is slowly deformed in elasticity by acting on the movable piece 300, so that the clamping force of the temple 20 gradually increases. In the unfolded position, the first elastic piece 410 can also be in an elastic deformation state, so that when the folding amplitude of the second support 200 is small, the second support 200 can receive a relatively large elastic force from the first elastic piece 410 through cooperation with the movable piece 300, so that the temple 20 has a large enough clamping force.

[0058] It can be understood that, under the premise that the first elastic piece 410 can provide clamping force when the temple 20 is folded outward, if the first elastic piece 410 is also required to assist when the temple 20 is folded inward, the design difficulty of the connection structure of the temple 20 will be increased, and the first elastic piece 410 is prone to failure. In the technical solution of the present application, when the user folds the temple 20, the first elastic piece 410 is separated from the movable piece 300, and the elastic force of the first elastic piece 410 cannot be transmitted to the second support 200, that is, the second support 200 will not be interfered with folding inward, which is beneficial to ensuring the smoothness of folding the temple 20.

[0059] Specifically, the first elastic piece 410 can be a tension spring or a compression spring, and can also be an elastic piece, a disc spring, a torsion spring, a variable-diameter spring, an air compression spring, etc.

[0060] Further, as shown in FIGS. 3-5, in the embodiment, the movable element 300 includes a connecting rod 330 and a first sliding element 310 and a second sliding element 320 connected by the connecting rod 330, the first support 100 is provided with a first sliding groove 110 and a second sliding groove 120, the first sliding element 310 is slidingly connected to the first sliding groove 110, the second sliding element 320 is slidingly connected to the second sliding groove 120, the second support 200 is connected to the first sliding element 310, and the first elastic element 410 is arranged between the first support 100 and the second sliding element 320. It should be noted that, in the embodiment, the first sliding groove 110 is configured in the form of a blind groove as shown in FIG. 3, and in FIGS. 5-8, the first support 100 has an arc-shaped through hole, which is for clearly showing the cooperation of the first sliding element 310 and other related structures with the first sliding groove 110, and the arc-shaped through hole is not an inherent structure of the first support 100.

[0061] In this way, when the second support 200 drives the first sliding element 310 to move along the first sliding groove 110, the second sliding element 320 can be driven by the connecting rod 330 to slide in the second sliding groove 120. When the second sliding element 320 slides in the second sliding groove 120 during the eversion of the temple leg 20, the first elastic element 410 can be acted on, and the elastic force of the first elastic element 410 can be transmitted to the second support 200 in sequence via the second sliding element 320, the connecting rod 330 and the first sliding element 310, thereby providing a clamping force for the temple leg 20. That is, in the embodiment, the second support 200 directly acts on the first sliding element 310, the first elastic element 410 directly acts on the second sliding element 320, and the force of the first elastic element 410 is indirectly transmitted by the connecting rod 330 inside the movable element 300. In this way, the stress of the movable element 300 can be dispersed, which is beneficial to ensuring the structural stability of the movable element 300, and the first sliding element 310 and the second sliding element 320 can respectively consider the positions of the second support 200 and the first elastic element 410. The displacement between the first sliding element 310 and the second sliding element 320 caused by the rotation of the second support 200 can be compensated by the connecting rod 330. Of course, in other embodiments, the movable element 300 can adopt other forms of structures, and as long as the structural strength of the movable element 300 meets the requirements, the force of the second support 200 on the movable element 300 and the force of the first elastic element 410 on the movable element 300 can also be concentrated in the same position.

[0062] Specifically, the first sliding member 310 and / or the second sliding member 320 are rotatably connected to the end of the connecting rod 330, respectively. That is, at least one of the first sliding member 310 and the second sliding member 320 and the connecting rod 330 are rotatably connected, so that the first sliding member 310 and the second sliding member 320 can slide more freely in the corresponding sliding groove, and the stress between the connecting rod 330 and the sliding member is small, and the connection between the connecting rod 330 and the sliding member is not easy to break, which is beneficial to ensure the structural stability of the movable piece 300.

[0063] Specifically, the first sliding member 310, the connecting rod 330, the first sliding groove 110 and the second sliding groove 120 are correspondingly provided as two, one first sliding member 310 is correspondingly connected to one first sliding groove 110, both ends of the second sliding member 320 are respectively connected to one second sliding groove 120, one connecting rod 330 is correspondingly connected to one of the first sliding member 310 and the second sliding member 320, and the two first sliding members 310 are arranged in a spaced manner to allow the electrical connecting member 600 between the temple 20 and the frame 10 to pass through. That is, the movable piece 300 is respectively matched with the two side walls of the first support 100 on the opposite sides, and the first sliding member 310 and the second sliding member 320 are matched by two connecting rods 330, so that the structural stability of the movable piece 300 and the matching stability of the movable piece 300 and the first support 100 can be improved. On this basis, the first sliding member 310 is provided as two spaced apart, providing a wire passing space for the electrical connecting member 600 between the temple 20 and the frame 10, and the wire passing space can stably exist after the temple 20 is folded, which can ensure that the electrical connecting member 600 at the connection of the temple 20 is not extruded, and is beneficial to ensure the stability of the electrical connection and signal transmission between the frame 10 and the temple 20.

[0064] Further, in the present embodiment, as shown in FIG. 2 and FIG. 5, the first support 100 is provided with a limiting protrusion 130, in the open position, the first elastic member 410 abuts against the limiting protrusion 130; when the second support 200 is folded outwards from the open position, the second sliding member 320 can drive the first elastic member 410 to abut against the limiting protrusion 130; when the second support 200 is folded inwards from the open position, the second sliding member 320 can drive the first elastic member 410 to abut against the limiting protrusion 130. It can be understood that the limiting protrusion 130 limits the first elastic member 410 in the distribution direction of the first elastic member 410 and the second sliding member 320. Without loss of generality, the first elastic member 410 is provided as a compression spring, in the open position, the same end of the first elastic member 410 abuts against the limiting protrusion 130 and the second sliding member 320, and the other end abuts against the second support 200. When the second support 200 is gradually folded outwards from the open position, the second sliding member 320 will move towards the side where the first elastic member 410 is located, thereby abutting against the first elastic member 410, so that the first elastic member 410 is gradually compressed, and the elastic potential energy of the first elastic member 410 is gradually accumulated. It can be understood that the greater the folding angle of the temple 20, the greater the risk of the head-mounted display device falling off, and the present embodiment provides greater clamping force through the first elastic member 410, which can effectively ensure the wearing stability of the head-mounted display device. In addition, after the temple 20 is folded outwards, if it is not affected by external force, the first elastic member 410 will release the elastic potential energy, thereby prompting the second support 200 to return to the open position, and the head-mounted display device will not maintain the posture of the temple 20 being folded outwards. When the second support 200 is folded inwards from the open position, the second sliding member 320 moves in the opposite direction, thereby gradually moving away from the first elastic member 410, so that the first elastic member 410 and the second support 200 are decoupled, and the second support 200 will not be affected by the force of the first elastic member 410.

[0065] In the present embodiment, in the open position, the first elastic member 410 is limited by the limiting protrusion 130, so that the first elastic member 410 can have a certain compression amount in the open position, so that when the folding amplitude of the second support 200 is small, the second support 200 can accept a relatively large elastic force from the first elastic member 410, thereby making the temple 20 have a large enough clamping force. Of course, in other embodiments, the first elastic member 410 can be in a natural state in the open position, so that when the second support 200 is folded inwards, the second sliding member 320 can be separated from the first elastic member 410.

[0066] Further, in the present embodiment, as shown in FIG. 2, FIG. 3 and FIG. 5, the temple 20 connecting structure further comprises a mounting member 500, which is located between the first elastic member 410 and the second sliding member 320, the first elastic member 410 is mounted on the mounting member 500, and in the open position, the mounting member 500 abuts against the limiting protrusion 130. It can be understood that when the second support 200 is in the open position, the mounting member 500 will also abut against the second sliding member 320, so that the first elastic member 410 can indirectly abut against the limiting protrusion 130 and the second sliding member 320 through the mounting member 500, and when the second support 200 is everted from the open position, the second sliding member 320 pushes the mounting member 500, thereby indirectly pressing the first elastic member 410. In the present embodiment, the mounting member 500 can provide a stable mounting environment for the first elastic member 410, so that the first elastic member 410 is not easily displaced. Of course, in other embodiments, the end of the first elastic member 410 can directly abut against the second sliding member 320 and the limiting protrusion 130.

[0067] Specifically, the cross section of the mounting member 500 is arc-shaped protruding away from the second sliding member 320, and in the open position, the second sliding member 320 is detachably engaged with the mounting member 500. That is, the shape of the outer wall surface of the second sliding member 320 and the mounting member 500 in abutting fit is an arc shape that is adapted to each other, which can increase the force receiving surface of the two to a certain extent, reduce the acting pressure between the two, and at the same time improve the uniformity of the force receiving of the two, thereby being beneficial to ensuring the stability of the abutting fit of the second sliding member 320 and the mounting member 500. Of course, in other embodiments, the mounting member 500 and the second sliding member 320 can be engaged and fitted by other shaped surfaces, or a resilient pad can be provided on any surface of the mounting member 500 or the second sliding member 320 to play a buffering role.

[0068] Specifically, the mounting member 500 protrudes with a mounting protrusion 510, and the first elastic member 410 is sleeved on the mounting protrusion 510. In this way, the mounting member 500 can stably mount the first elastic member 410, and the first elastic member 410 is not easily detached from the mounting member 500, that is, it can be stably located between the first support 100 and the movable member 300. In addition, the first elastic member 410 can be provided with one or more, and the mounting protrusion 510 is provided corresponding to the number of the first elastic member 410, and the end of the second elastic member 420 away from the mounting member 500 directly abuts against the wall of the first support 100. Of course, in other embodiments, the mounting member 500 can be recessed with a mounting hole, and the end of the first elastic member 410 is accommodated in the mounting hole.

[0069] Further, in the present embodiment, as shown in FIG. 3, the first sliding slot 110 is arc-shaped, and the second sliding slot 120 is linear. In this way, specifically, when the second support 200 rotates relative to the first support 100, the first sliding member 310 moves in the arc-shaped first sliding slot 110 and can well follow the second support 200, the second sliding slot 120 is linear, and the processing is simple, and meanwhile, the second sliding member 320 slides in the second sliding slot 120 and can meet the requirement that the second sliding member 320 follows the first sliding member 310. In the present embodiment, the first sliding member 310 and the second sliding member 320 respectively slide in the first sliding slot 110 and the second sliding slot 120 having the above-mentioned shapes, and the movement of the movable member 300 will be similar to the movement of a crank slider mechanism. Further, the length direction of the second sliding slot 120 is parallel to the axial direction of the first elastic member 410, and the second sliding slot 120 is arranged opposite to the first elastic member 410 in the width direction. It can be understood that the second sliding member 320 will slide in the second sliding slot 120 along the length direction of the second sliding slot 120, and in the present embodiment, the axis of the first elastic member 410 will coincide or approximately coincide with the symmetry axis of the second sliding slot 120, so that the force direction of the second sliding member 320 on the first elastic member 410 can be on or approximately on the same line as the elastic force of the first elastic member 410, the second sliding member 320 can more effectively press the first elastic member 410, and after the first elastic member 410 is compressed, the coaxiality of the forces acting on the first elastic member 410 is high, so that the first elastic member 410 is not easy to deviate in the radial direction, which is beneficial to guarantee the installation stability of the first elastic member 410. Of course, in other embodiments, the first sliding slot 110 and the second sliding slot 120 can be arranged in other shapes, wherein the first sliding slot 110 and the second sliding slot 120 can be slot structures of the same shape type having different extension directions.

[0070] Further, as shown in FIG. 2, in the embodiment, the temple 20 connecting structure further comprises a second elastic member 420 connected between the movable member 300 and the second support 200, and the elastic deformation amount of the second elastic member 420 first increases and then decreases during the switching of the support from the folded position to the unfolded position. That is, at an intermediate position (for the convenience of the following description, it is referred to as the maximum elastic position) between the folded position and the unfolded position, the elastic force on the second support 200 is the largest, and the elastic force on the elastic member 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 self-opening and closing of the temple 20. Moreover, when the elastic deformation amount 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, and the operation convenience of unfolding or folding the temple 20 is improved. Without loss of generality, in the unfolded position and the folded position, the second elastic member 420 is in a natural state, and the maximum elastic position is reached when the opening angle of the temple 20 relative to the frame 10 is about 45 degrees. The second elastic member 420 can be a tension spring or a compression spring, and can also be an elastic body such as a spring piece, a disc spring, a torsion spring, a variable-diameter spring, or an air compression spring.

[0071] Further, in the embodiment, please refer to FIGS. 5 to 9, the minimum distance between the first sliding groove 110 and the second sliding groove 120 is the distance between the first position 103 of the first sliding groove 110 and the second position of the second sliding groove 120, and the length of the connecting rod 330 is greater than the minimum distance; the first position 103 is located between the two ends of the first sliding groove 110, and the first sliding member 310 is located on the two sides of the first position 103 in the unfolded position and the folded position, respectively; the second position is located at one end of the second sliding groove 120, and the other end of the second sliding groove 120 extends away from the first position 103, and the second elastic member 420 abuts against the side of the sliding member away from the second position.

[0072] For convenience of description, the two ends of the first sliding groove 110 are referred to as the first end 101 and the second end 102 respectively, the two ends of the second sliding groove 120 are referred to as the third end 121 and the fourth end 122 respectively, the first position 103 of the first sliding groove 110 is between the first end 101 and the second end 102, and the second position of the second sliding groove 120 is at the third end 121. In addition, it should be noted that the sliding member being closer to a certain end of the corresponding sliding groove refers to being closer to the certain end relative to the other end of the sliding groove, that is, the distance between the sliding member and the certain end of the corresponding sliding groove is less than the distance between the sliding member and the other end, that is, the sliding member is closer to the certain end.

[0073] In the embodiment, as shown in FIGS. 5 and 6, when the second support 200 is in the open position, the first sliding member 310 is located between the first end 101 and the first position 103, and the second sliding member 320 is arranged close to the third end 121 and leaves a certain distance between the second sliding member 320 and the third end 121.

[0074] When the second support 200 is everted from the open position, the first sliding member 310 will slide towards the first end 101, and the second sliding member 320 will be driven to move towards the third end 121, thereby pressing the first elastic member 410, so as to provide clamping force for the temple 20 through the elastic force of the first elastic member 410. Without loss of generality, as shown in FIG. 9, when the second support 200 reaches the maximum everted position, the first sliding member 310 can abut against the end wall of the first end 101, and the second sliding member 320 can correspondingly abut against the end wall of the third end 121 to provide positioning and limiting effects.

[0075] Please refer to FIG. 6 to FIG. 8, when the second support 200 is folded from the unfolded position, the first sliding member 310 will slide towards the second end 102, before the first sliding member 310 reaches the first position 103, the second sliding member 320 will be pushed to slide towards the fourth end 122, the second sliding member 320 will be out of the pushing of the first elastic member 410, and start to push the second elastic member 420, so that the elastic deformation of the second elastic member 420 gradually increases. When the first sliding member 310 reaches the first position 103, the second sliding member 320 reaches the position closest to the fourth end 122, at this time, the second sliding member 320 can abut against the end wall of the fourth end 122, at this time, the elastic deformation of the second elastic member 420 reaches the maximum, and the second support 200 also reaches the maximum elastic position. When the first sliding member 310 continues to slide towards the second end 102 from the first position 103, the second sliding member 320 will be pulled to slide in the opposite direction of the third end 121, at this time, the pushing force of the second sliding member 320 on the second elastic member 420 decreases, and the second elastic member 420 gradually recovers the deformation, until the folding of the temple 20 is completed, and the first sliding member 310 will move to the position closest to the second end 102, at this time, the first sliding member 310 can reach the position of the second end 102.

[0076] In this way, depending on the relative position relationship between the first sliding groove 110 and the second sliding groove 120 in the embodiment, the first elastic member 410 can well provide the clamping force when the temple 20 is everted, and provide the elastic bow effect when the temple 20 is folded.

[0077] Further, the length direction of the second sliding groove 120 is parallel to the axial direction of the second elastic member 420, and the second sliding groove 120 is arranged opposite to the second elastic member 420 in the width direction. In this way, the axis of the second elastic member 420 coincides or approximately coincides with the symmetry axis of the second sliding groove 120, so that the force direction of the second sliding member 320 on the second elastic member 420 can be in or approximately in the same straight line as the elastic force of the second elastic member 420, the second sliding member 320 can more effectively press against the second elastic member 420, and the coaxiality of the forces on the second elastic member 420 after compression is high, so that the second elastic member 420 is not easy to deviate in the radial direction, which is beneficial to guarantee the installation stability of the second elastic member 420. Specifically, the first elastic member 410 and the second elastic member 420 are distributed on opposite sides of the second sliding member 320 along the length direction of the second sliding groove 120, the first support 100 is provided with an abutting protrusion 140 corresponding to the second elastic member 420, the second elastic member 420 is accommodated between the abutting protrusion 140 and the second sliding member 320, and the end of the second elastic member 420 can be connected to the abutting protrusion 140 in a way of embedding. Wherein, the first support 100 can be formed with an extension arm, the abutting protrusion 140 is arranged at the end of the extension arm, and the temple 20 is provided with a avoiding slot corresponding to the extension arm, or the end of the temple 20 is provided corresponding to the position of the abutting protrusion 140, so that the interference of the temple 20 with the first support 100 during rotation can be avoided.

[0078] Further, in the embodiment, the second support 200 is provided with a sliding protrusion 211 and is rotatably connected to the first sliding member 310, the sliding protrusion 211 avoids the first sliding member 310 and is slidably connected to the first sliding groove 110, so that the center of the first sliding groove 110 becomes the rotation center of the second support 200 relative to the first support 100. Specifically, the second sliding groove 120 is distributed on the side close to the temple 20, and the first sliding groove 110 is in an arc shape protruding towards the second sliding groove 120. When the temple 20 rotates relative to the frame 10, the sliding protrusion 211 can slide along the first sliding groove 110, so that the second support 200 rotates around the center of the first sliding groove 110, the sliding protrusion 211 and the first sliding member 310 avoid each other and can slide in the first sliding groove 110 in front of and behind each other, and the rotation cooperation of the second support 200 and the first sliding member 310 can well offset the change of the relative position of the two. Of course, in other embodiments, the second support 200 can be rotatably connected to the first support 100 through a rotating shaft.

[0079] Further, in the embodiment, the sliding protrusion 211 is arranged in an arc shape matching the first sliding groove 110, and the end of the first sliding groove 110 is provided with an avoiding gap 104, and part of the sliding protrusion 211 extends out of the avoiding gap 104 when the second support 200 is in the folded position. That is, after the temple 20 is folded in place, part of the sliding protrusion 211 extends out of the first sliding groove 110, and the remaining part is still in the first sliding groove 110, so that, on the one hand, the sliding protrusion 211 can be prevented from coming out of the first sliding groove 110, and on the other hand, the avoiding gap 104 can be blocked to prevent the first sliding member 310 from coming out of the avoiding gap 104.

[0080] Further, in the embodiment, as shown in FIGS. 3 and 4, the second support 200 includes two spaced apart arms 210, and the second support 200 is rotatably connected to the first sliding member 310 through the arms 210, and the two arms 210 extend into the first support 100, and the opposite sides of the two arms 210 are each provided with the sliding protrusion 211, and the first support 100 is correspondingly provided with two first sliding grooves 110, and one sliding protrusion 211 is correspondingly and slidingly connected to one first sliding groove 110. Specifically, one arm 210 is correspondingly and rotatably connected to one first sliding member 310, and at the same time, the two arms 210 can be matched with the interval between the two first sliding members 310 to improve the stability of the rotation of the second support 200. The interval between the two arms 210 does not interfere with the passing of the electrical connecting member 600 between the frame 10 and the temple 20, and is matched with the interval between the two first sliding members 310, so that the temple 20 connection structure of the embodiment can provide a larger bending radius for the electrical connecting member 600, reduce the bending risk of the electrical connecting member 600, and improve the bending service life of the head-mounted display device.
