[0041] SUMMARY Figures 1-4 As shown, according to one embodiment of the present application, a hinge assembly 1 is provided, which is applied to a head-mounted device, the hinge assembly 1 comprising a hinge body and a cover body 16 connected with the hinge body; a wire passing space is formed between the hinge body and the cover body 16, and an electrical connector of the head-mounted device is arranged in the wire passing space.

[0042] The hinge assembly 1 provided by the embodiment of the present application comprises a hinge body and a cover body 16, which are connected and form a wire passing space therebetween, and an electrical connector of a head-mounted device can be arranged in the wire passing space. The hinge assembly 1 provides a special wire passing space for the electrical connector of the head-mounted device, which facilitates the arrangement and installation of the electrical connector; solves the problem that the existing hinge assembly is not conducive to the arrangement of the electrical connector due to the structural and space limitations, and helps to reasonably arrange the internal circuit of the head-mounted device, which has a positive significance for the miniaturization design of the head-mounted device, while ensuring the normal electrical connection of the head-mounted device, improving the overall adaptability and portability of the head-mounted device, and further optimizing the user experience.

[0043] SUMMARY Figure 1As shown, in one embodiment, the hinge body comprises a first connecting body 11 and a second connecting body 12 connected in rotation, the volume of the first connecting body 11 is greater than that of the second connecting body 12, the first connecting body 11 is connected with the cover body 16 by mutual buckling and a wire passing space is formed therebetween.

[0044] In this specific example, the volume of the first connecting body 11 is larger, and buckling the first connecting body 11 with the cover body 16 to form the wire passing space can provide more abundant space for the electrical connection of the head-mounted device. Moreover, the wire passing space is formed by buckling the first connecting body 11 with the cover body 16, which not only facilitates the assembly of the hinge assembly, but also stably protects the electrical connection from external interference or damage during device use, ensuring that the electrical connection works stably and reliably.

[0045] Referring to Figure 1 As shown, in one embodiment, the wire passing space comprises a first wire passing space and a second wire passing space; the first connecting body 11 comprises a first half body 111 and a second half body 112 connected with each other, and the cover body 16 comprises a third half body 161 and a fourth half body 162 connected with each other;

[0046] The first half body 111 and the third half body 161 are connected by mutual buckling and a first wire passing space is formed therebetween, and the second half body 112 and the fourth half body 162 are connected by mutual buckling and a second wire passing space is formed therebetween;

[0047] The average width of the first wire passing space is smaller than that of the second wire passing space, the electrical connection is arranged straight in the first wire passing space, and the electrical connection is arranged at least partially bent in the second wire passing space.

[0048] In this specific example, the wire passing space comprises a first wire passing space with a smaller average width and a second wire passing space with a larger average width; wherein the first half body 111 of the first connecting body 11 and the third half body 161 of the cover body 16 are connected by mutual buckling to form the first wire passing space with a smaller average width; the second half body 112 of the first connecting body 11 and the fourth half body 162 of the cover body 16 are connected by mutual buckling to form the second wire passing space with a larger average width. The electrical connection is arranged straight in the first wire passing space and at least partially bent in the second wire passing space, so that the electrical connection occupies a smaller area in the first wire passing space and a larger area in the second wire passing space; in this way, the space can be reasonably allocated according to the actual needs and direction of the electrical connection, so that the electrical connection is arranged in an appropriate manner in different spaces, improving the space utilization rate, while meeting the wiring requirements of the electrical connection in different positions, further optimizing the internal layout of the head-mounted device.

[0049] Referring to Figure 1As shown, in one embodiment, the second half 112 and the fourth half 162 are convexly arranged away from each other.

[0050] In this specific example, the second half 112 of the first connecting body 11 and the fourth half 162 of the cover body 16 are convexly arranged away from each other, thereby providing a larger accommodation space for the second wire passing space, better adapting to the requirement of at least partially bending the electrical connecting member in the second wire passing space, ensuring that the electrical connecting member has sufficient space in the bent state, avoiding damage to the electrical connecting member due to insufficient space, and protecting the normal work and service life of the electrical connecting member.

[0051] Referring to Figure 1 As shown, in one embodiment, the second half 112 and the fourth half 162 are curved into an arc-shaped structure away from each other.

[0052] In this specific example, the second half 112 and the fourth half 162 are curved into an arc-shaped structure away from each other, which is smoother than the straight convex structure, not only further increasing the second wire passing space, but also reducing the local stress concentration on the electrical connecting member, reducing the risk of damage to the electrical connecting member due to stress concentration during bending, improving the reliability and stability of the electrical connecting member, and also helping to improve the overall aesthetics of the hinge assembly.

[0053] Referring to Figure 1 As shown, in one embodiment, the hinge body further comprises an elastic body 14, which is mounted to the first connecting body 11 and abuts against the second connecting body 12; the elastic body 14 is at least partially arranged between the second half 112 and the fourth half 162.

[0054] In this specific example, the hinge body is provided with an elastic body 14, which is mounted to the first connecting body 11 and abuts against the second connecting body 12 to provide elastic restoring force for the relative rotation of the first connecting body 11 and the second connecting body 12, and also helps to keep the first connecting body 11 and the second connecting body 12 stable after relative rotation to a certain position. The elastic body 14 is at least partially arranged between the second half 112 and the fourth half 162, and the elastic body 14 can also function as a buffer and shock absorber. During use of the head-mounted device, when the hinge assembly rotates or is impacted by external force, the elastic body can absorb and disperse part of the energy, reduce vibration and impact on the electrical connecting member, protect the electrical connecting member from damage, and also help to improve the service life and stability of the hinge assembly 1.

[0055] In addition, due to the larger size of the second wire passing space between the second half 112 and the fourth half 162, it is convenient to install and arrange the elastic body 14.

[0056] Referring to Figure 1 As shown in the figure, in one embodiment, the elastic body 14 is at least partially arranged between the second half body 112 and the electrical connecting member.

[0057] In this specific example, the elastic body 14 is at least partially arranged between the second half body 112 and the electrical connecting member, thereby further enhancing the protection of the electrical connecting member by the elastic body 14. When the hinge assembly is in motion or subjected to external force, the elastic body 14 can effectively buffer the pressure and impact force on the electrical connecting member, preventing the electrical connecting member from being damaged due to excessive compression or collision, and ensuring that the electrical connecting member always maintains good electrical performance.

[0058] Referring to Figure 1 , Figure 2 As shown in the figure, in one embodiment, the elastic body 14 includes a first elastic structure 141, a second elastic structure 142, and a main body portion 143 arranged between the first elastic structure 141 and the second elastic structure 142, and the second elastic structure 142 and the main body portion 143 are arranged between the second half body 112 and the electrical connecting member.

[0059] In this specific example, the elastic body 14 includes a first elastic structure 141, a second elastic structure 142, and a main body portion 143 arranged between the first elastic structure 141 and the second elastic structure 142; wherein the first elastic structure 141 is arranged in the first wire passing space, specifically between the first half body 111 and the electrical connecting member; the second elastic structure 142 and the main body portion 143 are arranged in the second wire passing space, specifically between the second half body 112 and the electrical connecting member; thereby more reasonably utilizing the wire passing space to arrange and install the elastic body 14, which is conducive to the compactness and miniaturization design of the hinge assembly.

[0060] Referring to Figure 1 As shown in the figure, in one embodiment, the electrical connecting member is a flexible circuit board 4.

[0061] In this specific example, the electrical connecting member is a flexible circuit board 4, which has the characteristics of being light and thin, bendable, foldable, etc., and is very suitable for application in head-mounted devices which have high requirements for space and weight; by arranging the flexible circuit board as the electrical connecting member in the wire passing space of the hinge assembly, it can better adapt to the rotation of the hinge assembly and the overall structure of the head-mounted device, while ensuring the reliability of the electrical connection, further optimizing the internal space layout of the head-mounted device, and helping to realize the miniaturization and lightweight design of the device.

[0062] In addition, referring to Figures 2-11 As shown in the figure, the hinge assembly 1 provided by the embodiments of the present application also has the following structural features:

[0063] The first connector 11 is provided with a limiting hole 1120, and the elastic body 14 is partially arranged in the limiting hole 1120, and the limiting hole 1120 provides a movement space for the elastic body 14.

[0064] The hinge assembly has a natural state and an eversion state, and in the case of switching of the hinge assembly from the natural state to the eversion state, the second connector 12 rotates in a first direction relative to the first connector 11, and the second connector 12 drives the elastic body 14 to move in the limiting hole 1120.

[0065] The hinge assembly 1 provided by the embodiment of the present application mainly comprises a first connector 11, a second connector 12 and an elastic body 14, wherein the second connector 12 is rotationally connected with the first connector 11, and more specifically, the hinge assembly 1 further comprises a rotation shaft 13, the first connector 11 is provided with a first through hole 110, the second connector 12 is provided with a second through hole 120, and the rotation shaft 13 is arranged in the first through hole 110 and the second through hole 120, so as to rotationally connect the first connector 11 and the second connector 12.

[0066] The elastic body 14 is mounted on the first connector 11 and abuts against the second connector 12, and the limiting hole 1120 provided in the first connector 11 provides a movement space for the elastic body 14, so that the hinge assembly 1 has a natural state and an eversion state; specifically, in the process of switching of the hinge assembly 1 from the natural state to the eversion state, the second connector 12 rotates in a first direction relative to the first connector 11, for example, the first direction is a clockwise direction; at the same time, the second connector 12 drives the structure of the elastic body 14 located in the limiting hole 1120 to move in the limiting hole 1120, so that the hinge assembly 1 can be smoothly switched from the natural state to the eversion state, and the eversion action is more stable and controllable, and the stability and reliability of the hinge assembly in use are ensured. In the case of application of the hinge assembly 1 to a head-mounted device, the eversion state of the hinge assembly 1 can adapt to the wearing of a user with a large head size, and improve the comfort of wearing; the hinge assembly 1 can provide an extension space according to different head sizes of users, improve the adaptability of the head-mounted device to the head, solve the problem that only the folding function cannot meet the comfortable wearing of users with different head sizes, and improve the user experience.

[0067] In one specific example of application of the hinge assembly 1 to a head-mounted device, the first connector 11 is connected with a frame 2 of the head-mounted device, and the second connector 12 is connected with a leg 3 of the head-mounted device; in the process of switching of the hinge assembly 1 from the natural state to the eversion state, the leg 3 is folded outward relative to the frame 2, so as to adapt to the wearing of a user with a large head size, and improve the comfort of wearing.

[0068] Reference Figure 2As shown, in one embodiment, the elastic body 14 includes a first elastic structure 141 and a second elastic structure 142, which are capable of relative elastic deformation; the first elastic structure 141 and the second elastic structure 142 are both mounted on the first connecting body 11, and the second elastic structure 142 abuts against the second connecting body 12;

[0069] The second elastic structure 142 is arranged through the limiting hole 1120, and the limiting hole 1120 provides a movement space for the second elastic structure 142; in the case of switching of the hinge assembly from the natural state to the outward-flipping state, the second connecting body 12 drives the second elastic structure 142 to move in the limiting hole 1120.

[0070] In this specific example, the elastic body 14 includes a first elastic structure 141 and a second elastic structure 142, which are capable of relative elastic deformation and are both mounted on the first connecting body 11, and the second elastic structure 142 abuts against the second connecting body 12 and is arranged through the limiting hole 1120, which provides a movement space for the elastic body 14, specifically, in the process of switching of the hinge assembly from the natural state to the outward-flipping state, the limiting hole 1120 provides a movement space for the second elastic structure 142, and the second connecting body 12 drives the second elastic structure 142 to move in the limiting hole 1120, so that the second elastic structure 142 is elastically deformed relative to the first elastic structure 141. The above structure further refines the composition of the elastic body 14, and through the interaction of the two elastic structures, the elastic force can be more flexibly adjusted, better adapting to the needs of different users, and at the same time, the movement of the elastic body 14 in the limiting hole 1120 is more accurate, improving the response speed and action accuracy of the hinge assembly 1.

[0071] Referring to Figure 6 As shown, in one embodiment, the first connecting body 11 has a first limiting end 1101 and a second limiting end 1102 corresponding to the limiting hole 1120; in the natural state of the hinge assembly, the second elastic structure 142 abuts against the first limiting end 1101, and in the case of switching of the hinge assembly from the natural state to the outward-flipping state, the second connecting body 12 drives the second elastic structure 142 to move from the first limiting end 1101 towards the second limiting end 1102.

[0072] In this specific example, in the natural state, the second elastic structure 142 abuts against the first limiting end 1101 of the limiting hole 1120, and the elastic body 14 is also in a natural state without elastic deformation. When the hinge assembly switches from the natural state to the outward folding state under the action of external force, the second connecting body 12 rotates relative to the first connecting body 11 in the positive direction of the first direction, for example, the positive direction of the first direction is clockwise. At the same time, the second connecting body 12 pushes the second elastic structure 142 to move from the first limiting end 1101 toward the second limiting end 1102, providing torque to the second connecting body 12, thereby forming a clamping force on the user's head of the temple connected to the second connecting body 12, so that the temple 3 folds outward relative to the frame 2, thereby adapting to the wear of users with larger head sizes and improving wearing comfort. When the hinge assembly is in the outward-folded state, a relative elastic deformation occurs between the first elastic structure 141 and the second elastic structure 142. The second connecting body 12 compresses the elastic body 14, and the elastic body 14 provides a rebound force and acts directly on the position where the second connecting body 12 abuts against the second elastic structure 142, thereby providing a clamping force for the hinge assembly during the outward-folding process.

[0073] When the external force is removed (e.g., when the user removes the head-mounted device), the hinge assembly returns to its natural state under the elastic restoring force of the elastomer 14, that is, the second elastic structure 142 resets to the first limiting end 1101 of the limiting hole 1120.

[0074] Optionally, the cross-section of the second elastic structure 142 is circular, while the limiting hole 1120 is an oblong hole.

[0075] Reference Figure 3 , Figure 5 As shown, in one embodiment, the first connecting body 11 includes a first half 111 and a second half 112 connected to each other. The first half 111 has a receiving groove 1110, and the second half 112 has the limiting hole 1120. The first elastic structure 141 is disposed in the receiving groove 1110.

[0076] In this specific example, the first connecting body 11 is configured as a first half 111 and a second half 112 that are connected to each other. The first half 111 is provided with a receiving groove 1110 to install the first elastic structure 141, and the second half 112 is provided with a limiting hole 1120 for the second elastic structure 142 to pass through. This makes the installation of the elastic body 14 more stable and orderly, and facilitates the assembly and maintenance of each component.

[0077] Reference Figure 2 , Figure 4As shown, in one embodiment, the hinge assembly 1 further comprises an adjusting member 15, which is in abutment with the first elastic structure 141 and can drive the first elastic structure 141 to move, so as to adjust the position of the first elastic structure 141 relative to the second elastic structure 142.

[0078] In this specific example, by arranging the adjusting member 15, the adjusting member 15 is in abutment with the first elastic structure 141 and can drive the first elastic structure 141 to move, so as to adjust the position of the first elastic structure 141 relative to the second elastic structure 142, thereby flexibly adjusting the elastic force provided by the elastic body 14, adjusting the pre-compression amount of the elastic body, thereby adjusting the pre-pressure of the elastic body, and providing different hinge clamping forces. That is, the initial installation angle between the first elastic structure 141 and the second elastic structure 142 of the elastic body 14 can be adjusted, thereby adjusting the resilience provided by the elastic body 14 to the second connecting body 12, and further adjusting the clamping force of the head-mounted device on the user's head; the problem that the position and elastic action relationship of the elastic element in the existing hinge assembly are fixed and cannot be adjusted is solved, the flexibility and maintainability of the hinge assembly are improved, and the use cost is reduced.

[0079] Referring to Figure 3 , Figure 4 As shown, in one embodiment, the adjusting member 15 penetrates through the first half body 111 at a position corresponding to the accommodating groove 1110 and is in abutment with the first elastic structure 141.

[0080] In this specific example, the adjusting member 15 penetrates through the first half body 111 at a position corresponding to the accommodating groove 1110 and is in abutment with the first elastic structure 141, so that the adjusting member 15 can directly and effectively act on the first elastic structure 141, thereby facilitating the position adjustment of the first elastic structure 141 by the adjusting member 15, and further achieving the adjustment of the elastic action of the elastic body 14.

[0081] Referring to Figure 4 As shown, in one embodiment, the adjusting member 15 is an adjusting screw, and the first half body 111 is provided with a threaded hole at a position corresponding to the accommodating groove 1110, and the adjusting member 15 is connected with the threaded hole in a matched manner.

[0082] In this specific example, an adjusting screw is adopted as the adjusting member 15, and a threaded hole is arranged at a position of the first half body 111 corresponding to the accommodating groove 1110 and connected therewith in a matched manner. This structure is simple and reliable, and the first elastic structure 141 can be conveniently and accurately driven to move by rotating the adjusting screw, thereby achieving accurate adjustment of the elastic action of the elastic body. In addition, the threaded connection has a certain self-locking property, which can ensure the stability of the adjusted position.

[0083] Referring toFigure 5 As shown in the figure, in one embodiment, the first half body 111 is provided with a first mounting hole 1111 for matching with the frame 2 in the head-mounted device.

[0084] In this specific example, the first half body 111 is provided with a first mounting hole 1111 for matching with the frame 2 in the head-mounted device, so that the hinge assembly 1 can be conveniently and stably mounted on the head-mounted device, facilitating the application of the hinge assembly in the head-mounted device.

[0085] Referring to Figure 7 As shown in the figure, in one embodiment, the second connecting body 12 includes a protruding part 121 and an edge part 122 connected with each other, and a transition arc part 123 is arranged between the protruding part 121 and the edge part 122, and the second elastic structure 142 abuts against the transition arc part 123 in the natural state of the hinge assembly.

[0086] In this specific example, the second connecting body 12 has a protruding part 121, an edge part 122, and a transition arc part 123 arranged therebetween; and in the natural state of the hinge assembly, the second elastic structure 142 abuts against the transition arc part 123, which is a recessed corner structure sandwiched between the protruding part 121 and the edge part 122, and the abutment of the second elastic structure 142 at this position can ensure the structural stability of the hinge assembly in the natural state; and in the process of switching the hinge assembly from the natural state to the outward turning state, the transition arc part 123 can stably and powerfully push the second elastic structure 142 to move from the first limiting end 1101 to the second limiting end 1102 of the limiting hole 1120, avoiding the slipping or loosening between the second connecting body 12 and the elastic body 14 in this process.

[0087] Referring to Figure 7 As shown in the figure, in one embodiment, the outer side of the protruding part 121 includes a first arc part 1211, a second arc part 1212, and a third arc part 1213 connected in sequence and arranged away from the transition arc part 123 in sequence; the hinge assembly has an inward folding state, and in the case of switching the hinge assembly from the natural state to the inward folding state, the second connecting body 12 reversely rotates relative to the first connecting body 11 in the first direction, and the first arc part 1211, the second arc part 1212, and the third arc part 1213 contact the second elastic structure 142 in sequence.

[0088] In the specific example, for example, the first direction is reversed as the counterclockwise direction, in the case that the second connecting body 12 rotates relative to the first connecting body 11 in the counterclockwise direction, the hinge assembly can be switched from the natural state to the inward folding state; and in the above rotating process, the protruding part 121 of the second connecting body 12 continuously contacts the second elastic structure 142, specifically, the first arc part 1211, the second arc part 1212 and the third arc part 1213 contact the second elastic structure 142 in turn, so that the second elastic structure 142 continuously provides the second connecting body 12 with the elastic force, ensuring the stability and rotating feeling of the hinge assembly when switching from the natural state to the inward folding state. In the process of switching the hinge assembly from the natural state to the inward folding state, the second elastic structure 142 always abuts against the first limiting end 1101 of the limiting hole 1120, and the protruding part 121 of the second connecting body 12 continuously contacts the second elastic structure 142 but does not push the second elastic structure 142 to shift.

[0089] In one specific example, referring to Figures 7-11 In the process that the first arc part 1211 and the second arc part 1212 contact the second elastic structure 142 in turn, corresponding to the acute angle of the hinge assembly inward folding (the second connecting body 12 rotates relative to the first connecting body 11 in the counterclockwise direction by an acute angle), the first arc part 1211 and the second arc part 1212 have a certain interference with the second elastic structure 142 in this process, the first arc part 1211 and the second arc part 1212 extrude the second elastic structure 142, and under the action of the elastic force of the second elastic structure 142, the hinge assembly has a tendency to return to the natural state; in the case that the second elastic structure 142 passes the first arc part 1211 and the second arc part 1212 and contacts the third arc part 1213, corresponding to the hinge assembly inward folding by about 90° (the second connecting body 12 rotates relative to the first connecting body 11 in the counterclockwise direction by about 90°), the third arc part 1213 naturally contacts but does not extrude the second elastic structure 142, so as to stabilize the second connecting body 12 at the position of rotating relative to the first connecting body 11 in the counterclockwise direction by about 90°.

[0090] Referring to Figure 7 In one embodiment, the second connecting body 12 further comprises a mounting body 124, the mounting body 124 is arranged on the side of the protruding part 121 away from the edge part 122; the mounting body 124 is provided with a second mounting hole 1240, and the second mounting hole 1240 is used for cooperating with the temple 3 in the head-mounted device.

[0091] In the specific example, the second connecting body 12 has the mounting body 124, and the mounting body 124 is provided with the second mounting hole 1240 for cooperating with the temple 3 in the head-mounted device, so that the hinge assembly 1 can be conveniently and stably connected with the temple 3, and the function of connecting the frame 2 and the temple 3 in the head-mounted device by the hinge assembly 1 can be easily realized.

[0092] Referring to Figure 3 、 Figure 5 As shown in the drawings, in one embodiment, the first connecting body 11 has oppositely and spaced apart bottom plate 1121 and partition plate 1122, the protruding part 121 and the edge part 122 are clamped between the bottom plate 1121 and the partition plate 1122, and are in contact with both the bottom plate 1121 and the partition plate 1122.

[0093] In this specific example, the second half 112 has oppositely and spaced apart bottom plate 1121 and partition plate 1122; wherein the bottom plate 1121 and the partition plate 1122 are both provided with first through hole 110 and limiting hole 1120, the first through hole 110 on the bottom plate 1121 and the first through hole 110 on the partition plate 1122 correspond to each other, and the limiting hole 1120 on the bottom plate 1121 and the limiting hole 1120 on the partition plate 1122 correspond to each other.

[0094] Clamping the protruding part 121 and the edge part 122 of the second connecting body 12 between the bottom plate 1121 and the partition plate 1122 and in contact with both of them can enhance the connection stability between the first connecting body 11 and the second connecting body 12, make the hinge assembly 1 more stable during rotation, reduce shaking and looseness, and improve the service life and performance of the hinge assembly 1. Moreover, during the rotation of the second connecting body 12 relative to the first connecting body 11, the protruding part 121 and the edge part 122 of the second connecting body 12 provide damping force through the friction with both of them, thereby realizing the damping feel of the hinge assembly 1 during rotation; and preventing the swinging of the glasses legs during the taking, placing and transferring of the head-mounted device, and maintaining the form of the head-mounted device.

[0097] In a specific example, the inner wall of the first through hole 110 formed in the bottom plate 1121 is internally threaded, and the rotating shaft 13 is threadedly connected with the bottom plate 1121, so as to ensure the stability of the rotating shaft 13 and not to affect the rotation of the second connecting body 12 relative to the first connecting body 11.
