[0002] With the rapid development of technology, head-mounted devices are playing an increasingly important role in people's daily lives and work. For example, virtual reality (VR) helmets, augmented reality (AR) glasses, and smart head-mounted displays provide users with immersive experiences and convenient ways to access information.

[0003] In the field of head-mounted devices, especially AR glasses, the hinge assembly, as the core structure connecting different parts of the device, directly determines the user experience and the overall adaptability and portability of the device.

[0025] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0027] Reference Figures 1-4 As shown, according to one embodiment of this application, a hinge assembly 1 is provided. The hinge assembly 1 is applied to a head-mounted device. The hinge assembly 1 includes a hinge body and a cover 16. The cover 16 is connected to the hinge body. A wire-passing space is formed between the hinge body and the cover 16. The electrical connector of the head-mounted device passes through the wire-passing space.

[0028] The hinge assembly 1 provided in this embodiment includes a hinge body and a cover 16, which are connected and form a wiring space between them, through which electrical connectors of the head-mounted device can be installed. This hinge assembly 1 provides a dedicated space for the electrical connectors of the head-mounted device, facilitating their arrangement and installation. It solves the problem that existing hinge assemblies are unsuitable for wiring due to structural and space limitations, contributing to a more rational layout of the internal wiring of the head-mounted device. This is significant for the miniaturization design of the head-mounted device, while ensuring normal electrical connection, improving the overall adaptability and portability of the head-mounted device, and ultimately optimizing the user experience.

[0029] Reference Figure 1 As shown, in one embodiment, the hinge body includes a first connecting body 11 and a second connecting body 12 that are rotatably connected. The volume of the first connecting body 11 is larger than the volume of the second connecting body 12. The first connecting body 11 and the cover body 16 are interlocked and connected to each other, and the wire passage space is formed between them.

[0030] In this specific example, the first connector 11 is relatively large, and its connection with the cover 16 to form a cable passage provides more ample space for the electrical connectors of the head-mounted device. Furthermore, the cable passage formed by the interlocking connection of the first connector 11 and the cover 16 facilitates the assembly of the hinge assembly and provides stable protection for the electrical connectors, preventing them from being affected by external interference or damage during device use, thus ensuring the stable and reliable operation of the electrical connectors.

[0031] Reference Figure 1 As shown, in one embodiment, the wire passage space includes a first wire passage space and a second wire passage space; the first connecting body 11 includes a first half 111 and a second half 112 connected to each other, and the cover 16 includes a third half 161 and a fourth half 162 connected to each other. The first half 111 and the third half 161 are interlocked and connected to each other, forming the first wire passage space between them; the second half 112 and the fourth half 162 are interlocked and connected to each other, forming the second wire passage space between them. The average width of the first wiring space is smaller than the average width of the second wiring space. The electrical connector is arranged straight in the first wiring space and at least partially bent in the second wiring space.

[0032] In this specific example, the wiring space includes a first wiring space with a smaller average width and a second wiring space with a larger average width. Specifically, the first half 111 of the first connector 11 and the third half 161 of the cover 16 are interlocked to form the first wiring space with a smaller average width; the second half 112 of the first connector 11 and the fourth half 162 of the cover 16 are interlocked to form the second wiring space with a larger average width. The electrical connector is arranged straight in the first wiring space and at least partially bent in the second wiring space, thus occupying a smaller area in the first wiring space and a larger area in the second wiring space. This allows for reasonable space allocation based on the actual needs and routing of the electrical connector, enabling the connector to be arranged appropriately in different spaces, improving space utilization, and meeting the wiring requirements of the connector in different locations, further optimizing the internal wiring layout of the head-mounted device.

[0033] Reference Figure 1 As shown, in one embodiment, the second half 112 and the fourth half 162 are both convex in a direction away from each other.

[0034] In this specific example, the second half 112 of the first connector 11 and the fourth half 162 of the cover 16 both protrude in a direction away from each other, thereby providing a larger accommodating space for the second wiring space. This better accommodates the electrical connector's requirement to be at least partially bent in the second wiring space, ensuring that the electrical connector has sufficient space when bent, avoiding damage to the electrical connector due to insufficient space, and guaranteeing the normal operation and service life of the electrical connector.

[0035] Reference Figure 1 As shown, in one embodiment, the second half 112 and the fourth half 162 are both curved in an arc shape, moving away from each other.

[0036] In this specific example, the second half 112 and the fourth half 162 are both bent into an arc shape in a direction away from each other. The arc shape is smoother than the straight protruding structure, which not only further increases the second wiring space, but also reduces the local stress concentration on the electrical connector, reduces the risk of damage to the electrical connector due to stress concentration during bending, improves the reliability and stability of the electrical connector, and also helps to improve the overall aesthetics of the hinge assembly.

[0037] Reference Figure 1 As shown, in one embodiment, the hinge body further includes an elastic body 14, which is mounted on the first connecting body 11 and abuts against the second connecting body 12; the elastic body 14 is at least partially disposed between the second half 112 and the fourth half 162.

[0038] In this specific example, the hinge body is provided with an elastic body 14, which is installed on the first connecting body 11 and abuts against the second connecting body 12. The elastic body 14 provides elastic restoring force for the relative rotation of the first connecting body 11 and the second connecting body 12, and also helps the first connecting body 11 and the second connecting body 12 remain stable after relative rotation to a specific position. The elastic body 14 is at least partially disposed between the second half 112 and the fourth half 162. The elastic body 14 also serves as a buffer and shock absorber. During the use of the head-mounted device, when the hinge assembly rotates or is subjected to external impact, the elastic body can absorb and disperse some of the energy, reducing vibration and impact on the electrical connectors, protecting the electrical connectors from damage, and also helping to improve the service life and stability of the hinge assembly 1.

[0039] Furthermore, since the second through space between the second half 112 and the fourth half 162 is relatively large, it facilitates the installation and arrangement of the elastomer 14.

[0040] Reference Figure 1As shown, in one embodiment, the elastomer 14 is at least partially disposed between the second half 112 and the electrical connector.

[0041] In this specific example, the elastomer 14 is at least partially disposed between the second half 112 and the electrical connector, thereby further enhancing the protective effect of the elastomer 14 on the electrical connector. When the hinge assembly moves or is subjected to external forces, the elastomer 14 can effectively buffer the pressure and impact forces on the electrical connector, preventing damage to the electrical connector due to excessive compression or collision, and ensuring that the electrical connector always maintains good electrical performance.

[0042] Reference Figure 1 , Figure 2 As shown, in one embodiment, the elastomer 14 includes a first elastic structure 141, a second elastic structure 142, and a main body portion 143 disposed between the first elastic structure 141 and the second elastic structure 142. The second elastic structure 142 and the main body portion 143 are both disposed between the second half 112 and the electrical connector.

[0043] In this specific example, the elastic body 14 includes a first elastic structure 141, a second elastic structure 142, and a main body 143 disposed between the two; wherein, the first elastic structure 141 is disposed in the first wiring space, specifically located between the first half 111 and the electrical connector; the second elastic structure 142 and the main body 143 are disposed in the second wiring space, specifically located between the second half 112 and the electrical connector; thereby, the wiring space can be used more rationally to arrange and install the elastic body 14, which is conducive to the compact and miniaturized design of the hinge assembly.

[0044] Reference Figure 1 As shown, in one embodiment, the electrical connector is a flexible circuit board 4.

[0045] In this specific example, the electrical connector is a flexible circuit board 4. Flexible circuit boards are thin, flexible, and foldable, making them very suitable for use in head-mounted devices, which have high requirements for space and weight. Using it as an electrical connector and passing it through the wiring space of the hinge assembly 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, it further optimizes the internal space layout of the head-mounted device, which helps to achieve the miniaturization and lightweight design of the device.

[0046] In addition, refer to Figures 2-11 As shown, the hinge assembly 1 provided in this embodiment of the application also has the following structural features: The first connector 11 has a limiting hole 1120, and the elastic body 14 is partially inserted through the limiting hole 1120, which provides the elastic body 14 with a space for movement. The hinge assembly has a natural state and an outward-folding state. When the hinge assembly switches from the natural state to the outward-folding state, the second connecting body 12 rotates relative to the first connecting body 11 in a first direction, and the second connecting body 12 drives the elastic body 14 to move within the limiting hole 1120. The hinge assembly 1 provided in this application embodiment mainly includes a first connecting body 11, a second connecting body 12, and an elastic body 14. The second connecting body 12 is rotatably connected to the first connecting body 11. More specifically, the hinge assembly 1 also includes a rotating shaft 13. The first connecting body 11 has a first through hole 110, and the second connecting body 12 has a second through hole 120. The rotating shaft 13 passes through the first through hole 110 and the second through hole 120, so that the first connecting body 11 and the second connecting body 12 are rotatably connected. The elastic body 14 is installed on the first connecting body 11 and abuts against the second connecting body 12. The limiting hole 1120 opened in the first connecting body 11 provides the elastic body 14 with a moving space, so that the hinge assembly 1 has a natural state and an outward-folding state. Specifically, during the process of the hinge assembly 1 switching from the natural state to the outward-folding state, the second connecting body 12 rotates relative to the first connecting body 11 in a positive first direction, for example, the positive first direction is clockwise. At the same time, the second connecting body 12 pushes the structure of the elastic body 14 located in the limiting hole 1120 to move within the limiting hole 1120, so that the hinge assembly 1 can smoothly switch from the natural state to the outward-folding state, making the outward-folding action more stable and controllable, and ensuring the stability and reliability of the hinge assembly during use. When the hinge assembly 1 is applied to a head-mounted device, the outward folding state of the hinge assembly 1 can accommodate users with larger head sizes, improving wearing comfort; the hinge assembly 1 can provide extension space according to different user head sizes, improving the fit between the head-mounted device and the head, solving the problem that the inward folding function alone cannot meet the comfortable wearing needs of users with different head sizes, and improving the user experience.

[0047] In a specific example of the application of the hinge assembly 1 in a head-mounted device, the first connector 11 is connected to the frame 2 of the head-mounted device, and the second connector 12 is connected to the temple 3 of the head-mounted device. During the process of the hinge assembly 1 switching from the natural state to the outward-folding state, 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.

[0048] 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 installed on the first connector 11, and the second elastic structure 142 abuts against the second connector 12. The second elastic structure 142 passes through the limiting hole 1120, and the limiting hole 1120 provides the second elastic structure 142 with a space for movement; when the hinge assembly switches from the natural state to the outward flipping state, the second connector 12 drives the second elastic structure 142 to move within the limiting hole 1120.

[0049] In this specific example, the elastic body 14 includes a first elastic structure 141 and a second elastic structure 142, both of which are capable of relative elastic deformation and are installed on the first connecting body 11. The second elastic structure 142 abuts against the second connecting body 12 and passes through a limiting hole 1120. The limiting hole 1120 provides the elastic body 14 with a space for movement. Specifically, during the transition of the hinge assembly from its natural state to its outward-folding state, the limiting hole 1120 provides the second elastic structure 142 with this space. The second connecting body 12 drives the second elastic structure 142 to move within the limiting hole 1120, causing the second elastic structure 142 to elastically deform relative to the first elastic structure 141. This structure further refines the composition of the elastic body 14. Through the interaction of the two elastic structures, the elastic force can be adjusted more flexibly to better adapt to the needs of different users. Simultaneously, the movement of the elastic body 14 within the limiting hole 1120 is more precise, improving the response speed and accuracy of the hinge assembly 1.

[0050] Reference 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, the second elastic structure 142 of the hinge assembly abuts against the first limiting end 1101; when the hinge assembly switches 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 toward the second limiting end 1102.

[0051] 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.

[0052] 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.

[0053] Optionally, the cross-section of the second elastic structure 142 is circular, while the limiting hole 1120 is an oblong hole.

[0054] 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.

[0055] 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.

[0056] Reference Figure 2 , Figure 4As shown, in one embodiment, the hinge assembly 1 further includes an adjusting member 15, which abuts against the first elastic structure 141 and is capable of driving 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.

[0057] In this specific example, by setting an adjusting member 15, which abuts against the first elastic structure 141 and can drive the first elastic structure 141 to move, the position of the first elastic structure 141 relative to the second elastic structure 142 can be adjusted. This allows for flexible adjustment of the elastic force provided by the elastic body 14, adjusting the pre-compression of the elastic body, and thus adjusting the pre-pressure of the elastic body, 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 magnitude of the rebound force provided by the elastic body 14 to the second connector 12, and further adjusting the clamping force of the head-mounted device on the user's head. This solves the problem that the position and elastic action relationship of the elastic elements in existing hinge assemblies are fixed and cannot be adjusted, improving the flexibility and maintainability of the hinge assembly and reducing the cost of use.

[0058] Reference Figure 3 , Figure 4 As shown, in one embodiment, the adjusting member 15 passes through the first half 111 at a position corresponding to the receiving groove 1110 and abuts against the first elastic structure 141.

[0059] In this specific example, the adjusting member 15 penetrates the first half 111 at the position corresponding to the receiving groove 1110 and abuts against the first elastic structure 141. This allows the adjusting member 15 to act directly and effectively on the first elastic structure 141, thereby facilitating the adjustment of the position of the first elastic structure 141 through the adjusting member 15, and thus realizing the adjustment of the elastic effect of the elastic body 14.

[0060] Reference Figure 4 As shown, in one embodiment, the adjusting member 15 is an adjusting screw, and the first half 111 has a threaded hole at a position corresponding to the receiving groove 1110, and the adjusting member 15 is connected to the threaded hole.

[0061] In this specific example, an adjusting screw is used as the adjusting element 15, and a threaded hole is opened at the position of the first half 111 corresponding to the receiving groove 1110 to connect with it. This structure is simple and reliable. By rotating the adjusting screw, the first elastic structure 141 can be easily and accurately driven to move in position, so as to achieve precise adjustment of the elastic effect of the elastic body. In addition, the threaded connection has a certain self-locking property, which can ensure the stability of the position after adjustment.

[0062] Reference Figure 5 As shown, in one embodiment, the first half 111 has a first mounting hole 1111, which is used to cooperate with the frame 2 in the head-mounted device.

[0063] In this specific example, a first mounting hole 1111 is provided in the first half 111 for connection with the frame 2 in the head-mounted device, so that the hinge assembly 1 can be conveniently and securely installed in the head-mounted device, thus facilitating the application of the hinge assembly in the head-mounted device.

[0064] Reference Figure 7 As shown, in one embodiment, the second connector 12 includes a protrusion 121 and an edge 122 connected to each other, and a transition arc 123 is provided between the protrusion 121 and the edge 122. In the natural state, the second elastic structure 142 abuts against the transition arc 123.

[0065] In this specific example, the second connector 12 has a protrusion 121, an edge 122, and a transition arc 123 disposed between the two. In the natural state, the second elastic structure 142 abuts against the transition arc 123, which is a recessed corner structure sandwiched between the protrusion 121 and the edge 122. The second elastic structure 142 abutting against this location ensures the structural stability of the hinge assembly in the natural state. Furthermore, during the transition of the hinge assembly from the natural state to the outward-folding state, the transition arc 123 can stably and forcefully push the second elastic structure 142 from the first limiting end 1101 of the limiting hole 1120 to the second limiting end 1102, preventing slippage or loosening between the second connector 12 and the elastic body 14 during this process.

[0066] Reference Figure 7 As shown, in one embodiment, the outer surface of the protrusion 121 includes a first arc portion 1211, a second arc portion 1212, and a third arc portion 1213 that are sequentially connected and sequentially away from the transition arc portion 123; the hinge assembly has an inward folded state, and when the hinge assembly switches from the natural state to the inward folded state, the second connecting body 12 rotates in the opposite direction to the first connecting body 11 in a first direction, and the first arc portion 1211, the second arc portion 1212, and the third arc portion 1213 sequentially contact the second elastic structure 142.

[0067] In this specific example, for instance, if the first direction is counterclockwise, when the second connector 12 rotates counterclockwise relative to the first connector 11, the hinge assembly can switch from its natural state to its inward-folding state. Furthermore, during this rotation, the protrusion 121 of the second connector 12 continuously contacts the second elastic structure 142; specifically, the first arc portion 1211, the second arc portion 1212, and the third arc portion 1213 sequentially contact the second elastic structure 142. Thus, the second elastic structure 142 continuously provides a restoring force to the second connector 12, ensuring the stability and tactile feel of the hinge assembly switching from its natural state to its inward-folding state. During the switching process, the second elastic structure 142 always abuts against the first limiting end 1101 of the limiting hole 1120. The protrusion 121 of the second connector 12 continuously contacts the second elastic structure 142 but does not push the second elastic structure 142 to shift.

[0068] In a specific example, refer to Figures 7-11 As shown, during the process of the first arc portion 1211 and the second arc portion 1212 sequentially contacting the second elastic structure 142, corresponding to the acute angle of inward folding of the hinge assembly (the acute angle of rotation of the second connecting body 12 relative to the first connecting body 11 in the counterclockwise direction), the first arc portion 1211 and the second arc portion 1212 have a certain interference with the second elastic structure 142. The first arc portion 1211 and the second arc portion 1212 compress the second elastic structure 142, and under the action of the rebound force of the second elastic structure 142, the hinge assembly tends to return to its natural state. When the second elastic structure 142 passes over the first arc portion 1211 and the second arc portion 1212 and contacts the third arc portion 1213, corresponding to the hinge assembly folding inward by approximately 90° (the second connecting body 12 rotates by approximately 90° in the counterclockwise direction relative to the first connecting body 11), the third arc portion 1213 naturally contacts but does not compress the second elastic structure 142, so that the second connecting body 12 is stabilized at a position where it has rotated approximately 90° counterclockwise relative to the first connecting body 11.

[0069] Reference Figure 7 As shown, in one embodiment, the second connector 12 further includes a mounting body 124, which is disposed on the side of the protrusion 121 away from the edge portion 122; the mounting body 124 has a second mounting hole 1240 for engaging with the temple 3 in the head-mounted device.

[0070] In this specific example, the second connector 12 has a mounting body 124, and the mounting body 124 has a second mounting hole 1240 for connecting with the temple 3 in the head-mounted device, so that the hinge assembly 1 can easily and securely connect the temple 3, and facilitate the function of the hinge assembly 1 in connecting the frame 2 and the temple 3 in the head-mounted device.

[0071] Reference Figure 3 , Figure 5 As shown, in one embodiment, the first connecting body 11 has a base plate 1121 and a partition plate 1122 that are opposite to each other and spaced apart. The protrusion 121 and the edge portion 122 are sandwiched between the base plate 1121 and the partition plate 1122 and are in contact with both the base plate 1121 and the partition plate 1122.

[0072] In this specific example, the second half 112 has a base plate 1121 and a partition plate 1122 that are arranged opposite to each other and spaced apart; wherein, both the base plate 1121 and the partition plate 1122 are provided with a first through hole 110 and a limiting hole 1120, the first through hole 110 on the base plate 1121 and the first through hole 110 on the partition plate 1122 correspond to each other, and the limiting hole 1120 on the base plate 1121 and the limiting hole 1120 on the partition plate 1122 correspond to each other.

[0073] The protrusion 121 and edge 122 of the second connector 12 are sandwiched between the base plate 1121 and the partition plate 1122 and are in contact with both. This enhances the connection stability between the first connector 11 and the second connector 12, making the hinge assembly 1 more stable during rotation, reducing wobbling and loosening, and improving the service life and performance of the hinge assembly 1. Furthermore, during the rotation of the second connector 12 relative to the first connector 11, the protrusion 121 and edge 122 of the second connector 12 provide damping force through contact and friction with both, thereby achieving a damped feel in the hinge assembly 1 during rotation; and preventing the temples from swinging during the removal, placement, and transfer of the head-mounted device, thus maintaining the shape of the head-mounted device.

[0074] Reference Figure 3 As shown, in one embodiment, the rotating shaft 13 has an external thread, and the first connecting body 11 has an internal thread corresponding to the inner wall of the first through hole 110. The rotating shaft 13 is threadedly connected to the first through hole 110.

[0075] In this specific example, the rotating shaft 13 has an external thread, and the first connecting body 11 has an internal thread corresponding to the inner wall of the first through hole 110, so that the rotating shaft 13 and the first through hole 110 form a threaded connection. Thus, the connection between the rotating shaft 13 and the first connecting body 11 is simple and reliable, and facilitates the installation and disassembly of the rotating shaft 13. At the same time, the threaded connection has a certain strength and stability, which can ensure the reliability of the rotating shaft 13 in the hinge assembly.

[0076] In a specific example, the inner wall of the first through hole 110 in the base plate 1121 has an internal thread, and the rotating shaft 13 and the base plate 1121 are connected by a threaded fit, thereby ensuring the stability of the installation of the rotating shaft 13 and not affecting the rotation of the second connecting body 12 relative to the first connecting body 11.

[0077] Reference Figure 1 As shown, in one embodiment, the elastic body 14 further includes a main body portion 143 disposed between the first elastic structure 141 and the second elastic structure 142; the elastic body 14 is a torsion spring, the first elastic structure 141 is a first torsion arm, the second elastic structure 142 is a second torsion arm, and the main body portion 143 is a helical spring body; the included angle between the first torsion arm and the second torsion arm is 90°+ / -5°.

[0078] In this specific example, the elastic body 14 also includes a main body 143 disposed between the first elastic structure 141 and the second elastic structure 142, and the elastic body 14 is specifically a torsion spring. The torsion spring has good elasticity and stability and can provide reliable elastic force for the hinge assembly to ensure its normal operation.

[0079] In this design, the first elastic structure 141 is the first torsion arm, and the second elastic structure 142 is the second torsion arm. The included angle between the first and second torsion arms is 90°+ / -5°. This specific angle design facilitates the installation of the torsion spring in the first connecting body 11. The receiving groove 1110 for installing the first torsion arm and the limiting hole 1120 for passing through the second torsion arm are respectively formed in the first half 111 and the second half 112. The arrangement of the receiving groove 1110 and the limiting hole 1120 is reasonable and does not interfere with each other, and it also ensures that the two torsion arms form a stable relative position in space, preventing connection failure due to loosening of the elastic structure. In addition, the included angle between the first and second torsion arms is 90°+ / -5°, which can produce appropriate elastic deformation under force, meeting the requirements of the hinge assembly's inward and outward folding functions, while ensuring the service life and performance stability of the torsion spring.

[0080] In other embodiments, in addition to a torsion spring, the elastomer 14 may also be a sheet, an air spring, or other forms of elastomer.

[0081] Reference Figure 3 , Figure 5 As shown, in one embodiment, the second half 112 is provided with a receiving cavity, and the main body 143 is installed in the receiving cavity.

[0082] In this specific example, a receiving cavity is provided in the second half 112 of the first connector 11 to install the main body 143 of the elastomer 14, which further optimizes the installation structure of the elastomer 14, making the overall installation of the elastomer 14 more compact and stable, which is conducive to improving the structural strength and reliability of the hinge assembly; and helps to reduce the overall volume of the hinge assembly.

[0083] According to another embodiment of this application, refer to Figure 12 As shown, a head-mounted device is provided, the head-mounted device including the hinge assembly 1 as described above; it also includes a frame 2 and temples 3, the frame 2 being connected to the first connecting body 11, and the temples 3 being connected to the second connecting body 12; when the hinge assembly is in its natural state, there is a gap between the frame 2 and the temples 3, which allows the frame 2 and the temples 3 to rotate outward and inward.

[0084] The head-mounted device provided in this embodiment includes the aforementioned hinge assembly 1, which provides reasonable space for electrical connectors, protects the electrical connectors, optimizes internal wiring layout, and improves device adaptability and portability. Therefore, this head-mounted device can better meet users' requirements for device performance and user experience, enhancing the product's competitiveness in the market.
