Description

[0002] With the rapid development of technology, head-mounted devices play an increasingly important role in people's daily life and work. For example, virtual reality (VR) headsets, augmented reality (AR) glasses, and smart head-mounted displays provide users with immersive experiences and convenient information acquisition methods.

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

[0004] Most existing hinge assemblies use fixed-structure elastic elements to achieve elastic force during folding. This fixed structure means that the relative positions and elastic action relationships between the elastic elements are fixed and cannot be adjusted flexibly according to actual use. For example, when the elastic force of the elastic elements changes due to long-term use or environmental factors and does not meet the requirements, since the relative positions of the elastic elements cannot be adjusted, the only way to solve the problem is to replace the entire hinge assembly or the elastic elements, which not only increases the use cost but also reduces the maintainability of the device.

[0042] SUMMARY Figures 1-3As shown, according to one embodiment of the present application, a hinge assembly 1 applied to a head-mounted device is provided, the hinge assembly 1 comprises a first connecting body 11, a second connecting body 12, a rotating shaft 13 and an elastic body 14, the first connecting body 11 is provided with a first through hole 110; the second connecting body 12 is provided with a second through hole 120; the rotating shaft 13 is arranged in 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 rotationally connected;

[0043] The elastic body 14 comprises a first elastic structure 141 and a second elastic structure 142, the first elastic structure 141 and the second elastic structure 142 can be elastically deformed relative to each other; 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;

[0044] Further comprising an adjusting member 15, the adjusting member 15 abuts against 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.

[0045] In the hinge assembly 1 provided by the embodiment of the present application, the rotating shaft 13 is used to realize the rotationally connecting of the first connecting body 11 and the second connecting body 12, the elastic body 14 is used to provide elastic force, and the elastic force of the elastic body 14 and the torque generated between the contact point of the second connecting body 12 and the elastic body 14 and the second through hole 120 are used to provide clamping force.

[0046] Wherein, the elastic body 14 comprises the first elastic structure 141 and the second elastic structure 142 which can be elastically deformed relative to each other; in addition, by arranging the adjusting member 15, the adjusting member 15 abuts against 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 the elastic force provided by the elastic body 14 can be flexibly adjusted, the pre-compression amount of the elastic body is adjusted, thereby the pre-pressure of the elastic body is adjusted, different hinge clamping forces are provided. 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 the elastic force provided by the elastic body 14 to the second connecting body 12 is adjusted, further the clamping force of the head-mounted device to the head of the user can be adjusted; the problem that the position of the elastic element and the elastic action relationship 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.

[0047] Reference Figure 4As shown, in one embodiment, the first connector 11 comprises a first half 111 and a second half 112 connected to each other, the first half 111 is provided with a receiving groove 1110, the second half 112 is provided with a limiting hole 1120, the first elastic structure 141 is arranged in the receiving groove 1110, and the second elastic structure 142 is arranged through the limiting hole 1120.

[0048] In this specific example, the first connector 11 is provided as a first half 111 and a second half 112 connected to each other, wherein the first half 111 is provided with a receiving groove 1110 for mounting 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; in this way, the mounting of the elastic body 14 is more stable and orderly, and the assembly and maintenance of each component are facilitated.

[0049] Referring to Figure 1 As shown, in one embodiment, the adjusting piece 15 penetrates the first half 111 at a position corresponding to the receiving groove 1110 and abuts against the first elastic structure 141.

[0050] In this specific example, the adjusting piece 15 penetrates the first half 111 at a position corresponding to the receiving groove 1110 and abuts against the first elastic structure 141, so that the adjusting piece 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 piece 15, and further realizing the adjustment of the elastic action of the elastic body 14.

[0051] Referring to Figure 3 As shown, in one embodiment, the adjusting piece 15 is an adjusting screw, the first half 111 is provided with a threaded hole at a position corresponding to the receiving groove 1110, and the adjusting piece 15 is connected with the threaded hole in a matched manner.

[0052] In this specific example, an adjusting screw is used as the adjusting piece 15, and a threaded hole is provided in the first half 111 at a position corresponding to the receiving 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 in position by rotating the adjusting screw, thereby realizing the accurate adjustment of the elastic action of the elastic body; and the threaded connection has a certain self-locking property, which can ensure the stability of the adjusted position.

[0053] Referring to Figure 4 As shown, in one embodiment, the first half 111 is provided with a first mounting hole 1111, and the first mounting hole 1111 is used to match the frame 2 in the head-mounted device to which the hinge assembly is applied.

[0054] In this specific example, the first half body 111 is provided with a first mounting hole 1111 for cooperating 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.

[0055] Referring to Figure 5 In one embodiment, the second half body 112 has a first limiting end 1101 and a second limiting end 1102 corresponding to the limiting hole 1120, and the hinge assembly has a natural state and an everted state. In the natural state, the second elastic structure 142 abuts against the first limiting end 1101. When the hinge assembly switches from the natural state to the everted state, the second connecting body 12 rotates in the first direction relative to the first connecting body 11, and 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.

[0056] In this specific example, the limiting hole 1120 provides a movement space for the elastic body 14, specifically, a movement space for the second elastic structure 142 during the switching of the hinge assembly from the natural state to the everted state.

[0057] Specifically, 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 the natural state without elastic deformation. When the hinge assembly switches from the natural state to the everted state under the action of an external force, the second connecting body 12 rotates in the first direction relative to the first connecting body 11, for example, in the clockwise direction. At the same time, 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, providing a torque for the second connecting body 12, and further forming a clamping force of the mirror leg pair connected by the second connecting body 12 on the user's head, so that the mirror leg 3 is folded outward relative to the frame 2 connected by the first connecting body 11, thereby adapting to the wearing of a user with a larger head size and improving the wearing comfort. In the everted state of the hinge assembly, the first elastic structure 141 and the second elastic structure 142 are elastically deformed relative to each other, the second connecting body 12 compresses the elastic body 14, and the elastic body 14 provides a resilient force directly acting on the position where the second connecting body 12 abuts against the second elastic structure 142, thereby providing a clamping force during the eversion of the hinge assembly.

[0058] When the external force is removed (for example, the user removes the head-mounted device), the hinge assembly returns to the natural state under the elastic restoring force of the elastic body 14, that is, the second elastic structure 142 is reset to the first limiting end 1101 of the limiting hole 1120.

[0059] Optionally, the second elastic structure 142 has a circular cross section, and the limiting hole 1120 is a waist-shaped hole.

[0060] Referring to Figure 2 , Figure 4 In one embodiment, the second half 112 is provided with a receiving cavity, and the elastic body 14 further includes a main body part 143 arranged between the first elastic structure 141 and the second elastic structure 142, and the main body part 143 is installed in the receiving cavity.

[0061] In this specific example, the receiving cavity is arranged in the second half 112 of the first connecting body 11 to install the main body part 143 of the elastic body 14, which further optimizes the installation structure of the elastic body 14, makes the overall installation of the elastic body 14 more compact and stable, and is beneficial to improve the structural strength and reliability of the hinge assembly; and helps to reduce the overall volume of the hinge assembly.

[0062] Referring to Figure 2 , Figure 4 In one embodiment, the second half 112 has a bottom plate 1121 and a partition plate 1122 arranged oppositely and spaced apart, and the second connecting body 12 is at least partially clamped between the bottom plate 1121 and the partition plate 1122 and in contact with both the bottom plate 1121 and the partition plate 1122.

[0063] In this specific example, the second half 112 has a bottom plate 1121 and a partition plate 1122 arranged oppositely and spaced apart; wherein the bottom plate 1121 and the partition plate 1122 are both provided with the first through hole 110 and the limiting hole 1120, the first through hole 110 arranged on the bottom plate 1121 corresponds to the first through hole 110 arranged on the partition plate 1122, and the limiting hole 1120 arranged on the bottom plate 1121 corresponds to the limiting hole 1120 arranged on the partition plate 1122.

[0064] Clamping at least part of the structure 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 structure of the second connecting body 12 clamped between the bottom plate 1121 and the partition plate 1122 provides damping force through the contact 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.

[0065] Referring to Figure 2As shown in the figure, in one embodiment, the rotating shaft 13 has external threads, and the first connecting body 11 is provided with internal threads corresponding to the inner wall of the first through hole 110, and the rotating shaft 13 is threadedly connected with the first through hole 110.

[0066] In this specific example, the rotating shaft 13 has external threads, and the first connecting body 11 is provided with internal threads corresponding to the inner wall of the first through hole 110, and the rotating shaft 13 is threadedly connected with the first through hole 110, so that the connection between the rotating shaft 13 and the first connecting body 11 is simple and reliable, facilitating the installation and disassembly of the rotating shaft 13; at the same time, the threaded connection has certain strength and stability, which can ensure the reliability of the rotating shaft 13 in the hinge assembly.

[0067] In one specific example, the inner wall of the first through hole 110 opened by the bottom plate 1121 has internal threads, and the rotating shaft 13 is threadedly connected with the bottom plate 1121, 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.

[0068] Referring to Figure 6 , 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 in the natural state of the hinge assembly, the second elastic structure 142 abuts against the transition arc part 123.

[0069] 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, and the transition arc part 123 is a recessed corner structure clamped 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.

[0070] Referring to Figure 6As shown, in one embodiment, the outer side of the protruding portion 121 comprises a first arc portion 1211, a second arc portion 1212 and a third arc portion 1213 connected in sequence and arranged away from the transition arc portion 123 in sequence; the hinge assembly has an inward folding state, in the case of switching of 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 along the first direction, and the first arc portion 1211, the second arc portion 1212 and the third arc portion 1213 contact the second elastic structure 142 in sequence.

[0071] In this specific example, for example, the first direction reverse is counterclockwise direction, in the case of rotating of the second connecting body 12 relative to the first connecting body 11 along 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 portion 121 of the second connecting body 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 contact the second elastic structure 142 in sequence, 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 switching of the hinge assembly from the natural state to the inward folding state. In the process of switching of 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 portion 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.

[0072] In one specific example, referring to Figures 6-10 As shown, in the process of the first arc portion 1211 and the second arc portion 1212 contacting the second elastic structure 142 in sequence, corresponding to the acute angle of inward folding of the hinge assembly (the second connecting body 12 rotates relative to the first connecting body 11 along the counterclockwise direction by an acute angle), the first arc portion 1211 and the second arc portion 1212 have a certain interference with the second elastic structure 142 in this process, the first arc portion 1211 and the second arc portion 1212 extrude the second elastic structure 142, and the hinge assembly has a tendency to return to the natural state under the action of the elastic force of the second elastic structure 142; in the case of the second elastic structure 142 passing through the first arc portion 1211 and the second arc portion 1212 and contacting the third arc portion 1213, corresponding to the hinge assembly inward folding by about 90° (the second connecting body 12 rotates relative to the first connecting body 11 along the counterclockwise direction by about 90°), the third arc portion 1213 naturally contacts but does not extrude the second elastic structure 142, so that the second connecting body 12 is stably positioned at the position of rotating relative to the first connecting body 11 by about 90° in the counterclockwise direction.

[0073] Referring to Figure 6As shown, in one embodiment, the second connecting body 12 further comprises a mounting body 124 disposed 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 for cooperating with the temple 3 in the head-mounted device to which the hinge assembly is applied.

[0074] In this 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 can be realized.

[0075] Referring to Figure 1 As shown, in one embodiment, the elastic body 14 further comprises a main body part 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 part 143 is a spiral spring body; the included angle between the first torsion arm and the second torsion arm is 90°+ / -5°.

[0076] In this specific example, the elastic body 14 further comprises the main body part 143 disposed between the first elastic structure 141 and the second elastic structure 142, and the elastic body 14 is specifically a torsion spring, which has good elasticity and stability, and can provide reliable elastic force for the hinge assembly to ensure normal work.

[0077] In this specific example, the elastic body 14 further comprises the main body part 143 disposed between the first elastic structure 141 and the second elastic structure 142, and the elastic body 14 is specifically a torsion spring, which has good elasticity and stability, and can provide reliable elastic force for the hinge assembly to ensure normal work.

[0078] In other embodiments, in addition to the torsion spring, the elastic body 14 can also be a spring sheet, an air spring, or other forms of elastic body.

[0079] Referring to Figure 11As shown, in one embodiment, the hinge assembly 1 further comprises a cover body 16 connected with the hinge body (consisting of the first connecting body 11 and the second connecting body 12); a wire passing space is formed between the hinge body and the cover body 16, and the electrical connector of the head-mounted device is arranged in the wire passing space.

[0080] In this specific example, a wire passing space is formed between the hinge body and the cover body 16 of the hinge assembly 1, and the electrical connector of the head-mounted device can be arranged in the wire passing space. The hinge assembly 1 provides a special arrangement space for the electrical connector of the head-mounted device, which is convenient for 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 structural and space limitations, helps the reasonable layout of the internal circuit of the head-mounted device, 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's experience.

[0082] In this specific example, the first connecting body 11 has a larger volume, and the buckling of the first connecting body 11 and the cover body 16 to form the wire passing space can provide more abundant arrangement space for the electrical connector of the head-mounted device. Moreover, the wire passing space is formed by the mutual buckling connection of the first connecting body 11 and the cover body 16, which not only facilitates the assembly of the hinge assembly, but also stably protects the electrical connector, prevents it from being disturbed or damaged by the outside during the use of the device, and ensures the stable and reliable work of the electrical connector.

[0083] Referring to Figure 11 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;

[0085] The average width of the first wire passing space is smaller than that of the second wire passing space, the electrical connector is arranged straight in the first wire passing space, and the electrical connector is at least partially arranged in a bent manner in the second wire passing space.

[0086] In this specific example, the wire-passing space includes 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 to each other by buckling to form the first wire-passing space with a smaller average width; and the second half body 112 of the first connecting body 11 and the fourth half body 162 of the cover body 16 are connected to each other by buckling to form the second wire-passing space with a larger average width. The electrical connecting member is arranged flat in the first wire-passing space and at least partially bent in the second wire-passing space, so that the electrical connecting member 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 connecting member, so that the electrical connecting member is arranged in an appropriate manner in different spaces, improving the space utilization rate, while meeting the wiring requirements of the electrical connecting member in different positions, further optimizing the internal layout of the head-mounted device.

[0087] Referring to Figure 11 In one embodiment, the second half body 112 and the fourth half body 162 are convexly arranged in directions away from each other.

[0088] In this specific example, the second half body 112 of the first connecting body 11 and the fourth half body 162 of the cover body 16 are both convexly arranged in directions away from each other, thereby providing a larger accommodation space for the second wire-passing space, better adapting to the needs of the electrical connecting member being at least partially bent in the second wire-passing space, and ensuring that the electrical connecting member has enough space in the bent state, avoiding damage to the electrical connecting member due to insufficient space, and protecting the normal operation and service life of the electrical connecting member.

[0089] Referring to Figure 11 In one embodiment, the second half body 112 and the fourth half body 162 are curved in an arc shape in directions away from each other.

[0090] In this specific example, the second half body 112 and the fourth half body 162 are curved in an arc shape in directions away from each other, and the arc shape is smoother than the straight convex structure, which not only further increases the second wire-passing space, but also reduces the local stress concentration on the electrical connecting member, reduces the risk of damage to the electrical connecting member due to stress concentration during bending, improves the reliability and stability of the electrical connecting member, and at the same time helps to improve the overall aesthetics of the hinge assembly.

[0091] Referring to Figure 11 In one embodiment, the elastic body 14 is mounted to the first connecting body 11 and abuts against the second connecting body 12; and the elastic body 14 is at least partially arranged between the second half body 112 and the fourth half body 162.

[0092] 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 an 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 to remain stable after relative rotation to a certain position. The elastic body 14 is at least partially arranged between the second half body 112 and the fourth half body 162, and the elastic body 14 can also play a role in buffering and shock absorption. 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 the vibration and impact on the electrical connector, protect the electrical connector from damage, and at the same time help to improve the service life and stability of the hinge assembly 1.

[0093] In addition, since the second wire passing space between the second half body 112 and the fourth half body 162 is relatively large, it is convenient to install and arrange the elastic body 14.

[0094] Referring to Figure 11 In one embodiment, the elastic body 14 is at least partially arranged between the second half body 112 and the electrical connector.

[0095] In this specific example, the elastic body 14 is at least partially arranged between the second half body 112 and the electrical connector, thereby further enhancing the protection of the electrical connector by the elastic body 14. When the hinge assembly moves or is impacted by external force, the elastic body 14 can effectively buffer the pressure and impact force on the electrical connector, prevent the electrical connector from being damaged due to excessive extrusion or collision, and ensure that the electrical connector always maintains good electrical performance.

[0096] Referring to Figure 11 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 both arranged between the second half body 112 and the electrical connector.

[0097] 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 connector; 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 connector; 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.

[0098] Referring to Figure 12As shown, in one embodiment, the electrical connector is a flexible circuit board 4.

[0099] In this specific example, the electrical connector is a flexible circuit board 4, which has the characteristics of thinness, bendability, foldability, etc., and is very suitable for application in a head-mounted device which has high requirements for space and weight; by using it as the electrical connector to pass through the wire 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, which helps to realize the miniaturization and lightweight design of the device.

[0100] According to another embodiment of the present application, referring to ​ As shown, a head-mounted device is provided, which comprises the hinge assembly 1 as described above; further comprising a frame 2 and a temple 3, the frame 2 is connected with the first connecting body 11, and the temple 3 is connected with the second connecting body 12; in the case that the hinge assembly is in a natural state, there is a gap between the frame 2 and the temple 3, which can facilitate the outward turning and inward folding rotation between the frame 2 and the temple 3.

[0101] The head-mounted device provided by the embodiments of the present application comprises the hinge assembly 1 described above, and because the hinge assembly 1 has the advantages of flexible adjustment of elastic action relationship, stable and reliable structure, etc., it makes the head-mounted device have better performance and user experience in folding, use, etc., and improves the overall quality and market competitiveness of the head-mounted device. For example, the head-mounted device is AR glasses.
