The present invention provides a hinge module 100.

Referring to fig. 1 and 5, in an embodiment of the present invention, the hinge module 100 includes a base 10, a bracket assembly 20, a homing assistance mechanism 30 and a folding assistance mechanism 40. The support assembly 20 is rotatably connected with the base 10, the support assembly 20 has a folding position, a critical position and an opening position which are sequentially arranged in the rotating direction relative to the base 10, the homing booster mechanism 30 and the folding booster mechanism 40 are in linkage fit with the support assembly 20 and can generate a force on the support assembly 20 along with the movement of the support assembly 20, when the support assembly 20 moves between the folding position and the critical position, the homing booster mechanism 30 and the folding booster mechanism 40 are used for providing a force for moving the support assembly 20 towards the folding position, when the support assembly 20 moves between the critical position and the opening position, the homing booster mechanism 30 is used for providing a force for moving the support assembly 20 towards the opening position, and the homing booster mechanism 30 provides a force which is larger than the folding booster mechanism 40 provides.

Specifically, as shown in fig. 17 and 18, the hinge module 100 may be used for a smart glasses 1000, the smart glasses 1000 including a frame 300 and a temple 200, wherein the temple 200 may be connected with a stand assembly 20, and the frame 300 is connected with a base 10, such that when the stand assembly 20 rotates relative to the base 10, the rotation of the temple 200 relative to the frame 300 may be achieved, thereby achieving folding and unfolding functions of the temple 200. Or two sets of bracket assemblies 20 may be provided, where two sets of bracket assemblies 20 are respectively rotatably connected with the base 10, one set of bracket assemblies 20 is used for being connected with the glasses leg 200, and the other set of bracket assemblies 20 is used for being connected with the glasses frame 300, so that when the bracket assemblies 20 connected with the glasses leg 200 rotate relative to the base 10, the folding and unfolding functions of the glasses leg 200 can be also achieved. As shown in fig. 1, in the present embodiment, two sets of bracket assemblies 20 are provided, namely, a first bracket assembly 20a for connecting the temple 200 and a second bracket assembly 20b for connecting the frame 300, and the first bracket assembly 20a and the second bracket assembly 20b are similar in structure, and for convenience of description, a first bracket assembly 20a for connecting the temple 200 (hereinafter, simply referred to as the bracket assembly 20) will be mainly described.

Referring to fig. 5 and 18, in the present embodiment, the stand assembly 20 is rotatably connected to the base 10, such that the stand assembly 20 has a folded position, a critical position, and an open position with respect to the base 10. When the hinge module 100 is applied to the smart glasses 1000, the stand assembly 20 may be connected to the temples 200 such that the temples 200 are in a folded state when the stand assembly 20 is in a folded position, the temples 200 are in a critical state when the stand assembly 20 is in a critical position, and the temples 200 are in an open state when the stand assembly 20 is in an open position. The hinge module 100 further includes a homing booster mechanism 30 and a folding booster mechanism 40 in linkage engagement with the stand assembly 20, the homing booster mechanism 30 being capable of changing a direction of an applied force to the stand assembly 20 after the stand assembly 20 passes the critical position while the direction of the applied force of the folding booster mechanism 40 to the stand assembly 20 remains unchanged when the stand assembly 20 moves between the folded position and the unfolded position.

As shown in fig. 5 and 18, the reverse folding process is similar to the movement process of the temple 200 from the folded state to the unfolded state, for example. When an external force is applied to the temple 200 to move the temple 200 from the folded state toward the unfolded state, if the temple 200 has not reached the adjacent state (for example, the turning angle of the temple 200 is smaller than 45 °), the stand assembly 20 is correspondingly located between the folded position and the critical position, at this time, the homing assistance mechanism 30 provides an acting force F1 for moving the stand assembly 20 toward the folded position, the folding assistance mechanism 40 provides an acting force F2 for moving the stand assembly 20 toward the folded position, and since the directions of F1 and F2 are the same, when the external force is removed during the movement, the stand assembly 20 can automatically return to the folded position under the resultant force of (f1+f2), thereby driving the temple 200 to automatically return to the folded state. When the temple 200 moves to a critical state (e.g., the flip angle of the temple 200 reaches a critical angle of 45 °), the bracket assembly 20 is accordingly in a critical position, which is an instantaneous steady-state position. When external force is continuously applied to the glasses leg 200 to enable the glasses leg 200 to pass through a critical state (for example, the turning angle of the glasses leg 200 is larger than the critical angle of 45 degrees), correspondingly, the support assembly 20 is between a critical position and an open position, at this time, the homing assistance mechanism 30 provides an acting force F3 for the support assembly 20 to move towards the open position, the folding assistance mechanism 40 provides an acting force F4 for the support assembly 20 to move towards the folded position, at this time, F3 is opposite to F4, and F3 is far larger than F4, and when the external force is removed during movement, the support assembly 20 can automatically move to the open position under the action of resultant force of (F3-F4), so that the glasses leg 200 is driven to automatically move to the open state.

The hinge module 100 according to the present invention is configured such that the support assembly 20 is rotatably connected to the base 10, and when applied to the smart glasses 1000, the temple 200 is connected to the support assembly 20, so that the temple 200 can move between an open state and a folded state, and the support assembly 20 is positioned between the folded position and the critical position after the temple 200 passes through the critical state during folding, by providing the homing assistance mechanism 30 and the folding assistance mechanism 40, and at this time, the homing assistance mechanism 30 and the folding assistance mechanism 40 are both used to provide an acting force for the support assembly 20 to move toward the folded position, and since the folding assistance mechanism 40 plays a positive assistance role during folding, the folding torque applied to the temple 200 can be increased, so that the temple 200 can be folded in place quickly and compressed after being in place. When the temple 200 passes over the critical state during the opening process, the support assembly 20 is between the critical position and the open position, at this time, the homing booster mechanism 30 is used for providing a force for moving the support assembly 20 towards the open position, the folding booster mechanism 40 is used for providing a force for moving the support assembly 20 towards the folding position, and the force provided by the homing booster mechanism 30 is greater than the force provided by the folding booster mechanism 40, and since the folding booster mechanism 40 plays a role of reverse resistance during the opening process, a part of the force generated by the homing booster mechanism 30 can be offset, so that the unfolding torque applied to the temple 200 is reduced, the opening speed of the temple 200 is relatively slow, and the effect of gently opening the temple is achieved. According to the technical scheme, the glasses legs 200 have different force senses in the opening direction and the folding direction, two different effects of rapid folding in place and gentle opening in place can be achieved at the same time, the situation that the users are injured by mistake due to the fact that the glasses legs 200 are opened too fast can be avoided, the overall texture of the intelligent glasses 1000 is improved, and further user experience can be effectively improved.

Referring to fig. 6 and 7, in one embodiment, the homing assistance mechanism 30 includes a first cam 31 and a follower component 32, the first cam 31 is connected to the bracket component 20 and can rotate along with the bracket component 20, a tooth 311 is disposed on an axial end surface of the first cam 31, the tooth 311 has a first extrusion inclined surface 3111 and a second extrusion inclined surface 3112 with opposite inclination directions, the follower component 32 can elastically and telescopically abut against one side of the first cam 31 where the tooth 311 is disposed, and a first guide inclined surface 3211 and a second guide inclined surface 3212 with opposite inclination directions are disposed on a side of the follower component 32 opposite to the tooth 311, when the bracket component 20 moves between the folded position and the critical position, the first extrusion inclined surface 3111 extrudes and slides along the first guide inclined surface 3211, and when the bracket component 20 moves between the critical position and the open position, the second extrusion inclined surface 3112 extrudes and slides along the second guide inclined surface 3212.

In this embodiment, when the temple 200 rotates from the folded state to the critical state, the first cam 31 is driven by the bracket assembly 20 to rotate, and then the first pressing inclined surface 3111 of the first cam 31 can slide along the first guiding inclined surface 3211 and generate a pressing force on the first guiding inclined surface 3211, so that the follower assembly 32 is compressively deformed, and the follower assembly 32 can generate a reverse thrust on the bracket assembly 20 under the action of the resilience force, so that the temple 200 has a tendency to move toward the folded state. When the temple 200 moves from the critical state to the open state, the first cam 31 is driven by the bracket assembly 20 to rotate, and then the second pressing inclined surface 3112 of the first cam 31 can slide along the second guiding inclined surface 3212 and generate pressing force on the second guiding inclined surface 3212, so that the follower assembly 32 is compressively deformed, and the follower assembly 32 can generate a thrust against the bracket assembly 20 under the action of resilience force, so that the temple 200 has a tendency of moving towards the open state. By matching the first cam 31 with the follower component 32, the acting force direction of the homing power assisting mechanism 30 in the rotation process of the glasses leg 200 can be changed, and then the functions of automatic folding homing and automatic unfolding homing are realized.

It should be noted that, the first cam 31 may be integrally connected to the bracket assembly 20 by welding or a fastener, or the first cam 31 may be integrally formed with the bracket assembly 20, that is, the first cam 31 is formed as a part of the bracket assembly 20, for example, as shown in fig. 4, in this embodiment, the first cam 31 is integrally formed with the bracket assembly 20. The shaft end surface of the first cam 31 is provided with the protruding teeth 311, and the protruding teeth 311 have a first pressing inclined surface 3111 and a second pressing inclined surface 3112 which are inclined in opposite directions, so that the protruding teeth 311 have a substantially triangular or trapezoidal structure. The follower component 32 is disposed at one axial side of the first cam 31, the follower component 32 can elastically stretch and retract along the axial direction of the first cam 31, that is, the follower component 32 has a certain elasticity, when the first cam 31 applies an axial force to the follower component 32, the follower component 32 can be compressively deformed, and meanwhile, the follower component 32 can have a tendency of stretching and resetting towards the first cam 31 under the rebound action, so that the follower component 32 and the first cam 31 always keep in contact. In this embodiment, the follower assembly 32 includes a slider 321 and an elastic restoring member 322, where the slider 321 is opposite to the first cam 31, the elastic restoring member 322 is elastically abutted to a side of the slider 321 away from the first cam 31, and the elastic restoring member 322 elastically stretches and stretches the slider 321 along the axial direction relative to the first cam 31, and of course, in other embodiments, the follower assembly 32 can also elastically stretch and contract through some mechanical linkage structures or transmission structures, which is not limited herein.

Referring to fig. 4 and 6, further, the base 10 is provided with a connecting shaft 50, the first cam 31 is rotatably sleeved on the connecting shaft 50, the follower assembly 32 includes a slider 321 and an elastic restoring member 322, the slider 321 is slidably sleeved on the connecting shaft 50 along an axial direction, a first guiding inclined plane 3211 and a second guiding inclined plane 3212 are disposed on a side of the slider 321 opposite to the first cam 31, and the elastic restoring member 322 is sleeved on the connecting shaft 50 and elastically abuts against a side of the slider 321 facing away from the first cam 31.

In this embodiment, the bracket assembly 20 is rotatably sleeved on the connecting shaft 50 through the first cam 31, so as to realize rotatable connection between the bracket assembly 20 and the base 10. The sliding of the sliding block 321 and the elastic telescopic movement of the elastic restoring piece 322 can be guided by the connecting shaft 50, so that the whole homing compensation mechanism has higher movement precision. Wherein the resilient return member 322 includes, but is not limited to, a compression spring, a rectangular spring, a wave spring, a disc spring, or other form of resilient member.

Referring to fig. 5 to 7, the movement process of the temple 200 from the folded state to the unfolded state is taken as an example, and the reverse folding process is similar. When an external force is applied to the glasses leg 200 to enable the glasses leg 200 to move from a folded state to an adjacent state, a folding torsion force F2 for enabling the folding power assisting mechanism 40 to apply to the bracket assembly 20 to move towards a folded position is applied to the bracket assembly 20, the external force overcomes the folding torsion force to enable the bracket assembly 20 to rotate towards a critical position relative to the base 10, at the moment, the first cam 31 on the bracket assembly 20 moves along the first guide inclined plane 3211 of the sliding block 321 through the first pressing inclined plane 3111 and generates pressing force on the sliding block 321, so that the sliding block 321 moves axially and enables the elastic reset piece 322 to compress and deform, and accordingly reverse thrust F1 is achieved, if the external force is withdrawn in the moving process, the bracket assembly 20 automatically returns to the folded position under the combined action of the acting force F1 formed by the homing power assisting mechanism 30 (namely the first cam 31, the matching structure of the sliding block 321 and the elastic reset piece 322), and the acting force F2 generated by the folding power assisting mechanism 40, so that the glasses leg 200 is quickly and automatically reset to the folded state. When the external force is continuously applied to move the glasses leg 200 towards the open state beyond the critical state, the first cam 31 moves along the second guiding inclined plane 3212 of the sliding block 321 through the second pressing inclined plane 3112 and generates pressing force on the sliding block 321, so that the sliding block 321 moves along the axial direction and the elastic restoring member 322 is compressively deformed, thereby realizing the reverse thrust force F3, the direction of the generated reverse thrust force F3 is changed compared with that of the first guiding inclined plane 3211 due to the change of the second guiding inclined plane 3212, and the F3 is far greater than the folding torsion force F4 generated by the folding power assisting mechanism 40, if the external force is removed in the moving process, the bracket assembly 20 moves towards the open position under the action of the acting force F3 formed by the folding power assisting mechanism 30 (namely, the cooperation structure of the first cam 31, the sliding block 321 and the elastic restoring member 322), and the folding torsion force F4 generated by the folding power assisting mechanism 40 is opposite to the direction of the F3, so that a part of the acting force generated by the folding power assisting mechanism 30 can be offset, and the unfolding torque applied to the glasses leg 200 is reduced, thereby the opening speed of the glasses leg 200 is relatively slow, and the slow opening effect is achieved.

In one embodiment, as shown in fig. 7, a third guiding inclined plane 3213 is further provided on the opposite side of the follower component 32 to the convex tooth 311, the third guiding inclined plane 3213 is located on the side of the second guiding inclined plane 3212 away from the first guiding inclined plane 3211, the third guiding inclined plane 3213 is opposite to the tilting direction of the second guiding inclined plane 3212, a stop slot 3214 is formed between the third guiding inclined plane 3213 and the first guiding inclined plane 3211, when the bracket component 20 is in the open position, the convex tooth 311 is engaged with the stop slot 3214, and when the bracket component 20 is subjected to an eversion force, the first extrusion inclined plane 3111 extrudes and slides along the third guiding inclined plane 3213.

In this embodiment, when the bracket assembly 20 is in the open position, the protruding teeth 311 of the first cam 31 are engaged with the stop grooves 3214 of the slider 321, so that the bracket assembly 20 can be stably maintained in the open position, and the temple 200 can be stably maintained in the open state without shaking left and right, so that the overall texture of the product can be effectively improved. When a user wears glasses, an eversion torque is applied to the glasses leg 200, the glasses leg 200 is unfolded and drives the bracket component 20 to rotate, the first cam 31 rotates along with the eversion torque, the glasses leg 200 is provided with a certain eversion adjusting space to adapt to users with different head widths by sliding along the third guide inclined plane 3213 through the first extrusion inclined plane 3111 of the first cam 31, the first extrusion inclined plane 3111 extrudes the third guide inclined plane 3213, the follower component 32 is compressed and deformed, the follower component 32 can generate a reverse thrust to the bracket component 20 under the action of resilience force, and then the glasses leg 200 generates a clamping force to the head of the user, so that the user can wear the glasses without being too loose or too tight, and wearing the glasses more comfortably. After the glasses are taken down, the glasses legs 200 can be automatically restored and kept in the open state, and the phenomenon of shaking left and right can not occur, so that a high-grade feeling is provided for a user, and the user experience is improved.

In the above embodiment, when the user with a larger head width wears the glasses leg 200, the bracket assembly 20 is driven to turn outwards, the bracket assembly 20 drives the first cam 31 to rotate, the first extrusion inclined surface 3111 contacts with the third guiding inclined surface 3213, the sliding block 321 is driven to move downwards and compress the elastic resetting member 322 to provide resistance torque, so as to apply a clamping force to the head of the user, and the clamping force becomes larger and larger as the angle of the outer tension of the glasses leg 200 becomes larger. When worn by a user with a smaller head width, the clamping force generated by eversion is relatively small due to the smaller angle of the temple 200. Therefore, the difference between the clamping force sensed by the user with smaller head width value and the user with larger head width value when wearing the same pair of intelligent glasses 1000 is larger, so that the adaptability of the intelligent glasses 1000 is poorer, and the wearing feeling of the user is affected.

In order to solve the above problems, as shown in fig. 8 and 10, further, the hinge module 100 further includes a clamping force compensating mechanism 60 provided between the base 10 and the bracket assembly 20, wherein the clamping force compensating mechanism 60 is used to provide an auxiliary clamping force for the bracket assembly 20 to turn inward when the eversion angle of the bracket assembly 20 is smaller than a preset angle, and the auxiliary clamping force increases as the eversion angle of the bracket assembly 20 increases, and the auxiliary clamping force remains constant or is removed when the eversion angle of the bracket assembly 20 is greater than the preset angle.

In the present embodiment, by providing the clamping force compensation mechanism 60 between the base 10 and the bracket assembly 20, the effect that the clamping force values of the temple 200 are not greatly different in both the small angle eversion and the large angle eversion, and are relatively balanced, can be achieved. Specifically, when the user with a smaller head width wears the glasses leg 200 and the support assembly 20, the everting angle of the glasses leg 200 and the support assembly 20 is smaller, so that the compression deformation amount of the elastic reset piece 322 of the follow-up assembly 32 is smaller, and further, the inward turning clamping force generated by the homing assistance mechanism 30 on the support assembly 20 is smaller, when the everting angle of the support assembly 20 is smaller than a preset angle (the preset angle can be set according to actual needs), the clamping force compensation mechanism 60 can provide the auxiliary inward turning clamping force for the support assembly 20, and in the range that the everting angle is smaller than the preset angle, the auxiliary clamping force is increased along with the increase of the everting angle, and at this time, the clamping force sensed by the user wearing is provided by the homing assistance mechanism 30 and the clamping force compensation mechanism 60 at the same time. When the user with a larger head width wears the glasses leg 200 and the support assembly 20, the everting angle of the glasses leg 200 and the support assembly 20 is larger, so that the compression deformation amount of the elastic reset piece 322 of the follow-up assembly 32 is also larger, and further, the inward-turning clamping force generated by the homing assistance mechanism 30 on the support assembly 20 is also larger, when the everting angle of the support assembly 20 is larger than a preset angle, the clamping force compensation mechanism 60 provides the auxiliary clamping force for the support assembly 20 to turn inwards to keep constant or withdraw, and at the moment, the clamping force felt by the user wearing the glasses leg is mainly provided by the homing assistance mechanism 30. Therefore, the difference of the clamping force felt by the user with smaller head width value and the user with larger head width value when wearing the same pair of intelligent glasses 1000 is smaller, the adaptability of the intelligent glasses 1000 is better, and the wearing feeling of the user can be effectively improved.

There are a variety of specific implementations of the clamping force compensation mechanism 60, and two embodiments of the clamping force compensation mechanism 60 are illustrated below.

As shown in fig. 4 and 8, in one embodiment, the clamping force compensating mechanism 60 includes a booster elastic member 61 and a trigger member 62, wherein the booster elastic member 61 is disposed between the base 10 and the bracket assembly 20, the trigger member 62 is disposed on one side of the bracket assembly 20 near the booster elastic member 61, when the everting angle of the bracket assembly 20 is smaller than a preset angle, the trigger member 62 is in interference contact with the booster elastic member 61, and the interference increases with the increase of the everting angle of the bracket assembly 20, and when the everting angle of the bracket assembly 20 is larger than the preset angle, the interference between the trigger member 62 and the booster elastic member 61 is kept constant or zero.

In this embodiment, the power assisting elastic member 61 includes, but is not limited to, a spring, a shrapnel, or other elastic structure. Taking the elastic piece as an example, the elastic piece 61 comprises an elastic piece body and a folded edge arranged on the side part of the elastic piece body, and the folded edge is obliquely folded towards one side close to the bracket assembly 20 relative to the elastic piece body. The bracket assembly 20 is provided with a trigger piece 62 protruding towards one side of the power-assisted elastic piece 61, and the trigger piece 62 can be in interference fit with the folded edge of the power-assisted elastic piece 61. For example, when the bracket assembly 20 is turned outwards by a first angle, and the first angle is smaller than a preset angle, the trigger piece 62 is in interference contact with the power-assisted elastic piece 61 at a first position, the power-assisted elastic piece 61 is pressed by the trigger piece 62, so that a reverse acting force is generated by the power-assisted elastic piece 61, the reverse acting force can provide an auxiliary clamping force for the bracket assembly 20, so that the overall clamping force is increased, when the bracket assembly 20 is turned outwards by a second angle, which is larger than the first angle and smaller than the preset angle, the trigger piece 62 is in interference contact with the power-assisted elastic piece 61 at a second position, which is larger than the first position, so that the power-assisted elastic piece 61 generates a larger reverse acting force to further increase the auxiliary clamping force, when the bracket assembly 20 is turned outwards further, the trigger piece 62 passes over the second position, the interference between the trigger piece 62 and the power-assisted elastic piece 61 is not changed any more, the reverse acting force provided by the power-assisted elastic piece 61 is constant, so that the auxiliary clamping force is kept constant, and the main clamping force is provided by the main clamping mechanism 30. In this embodiment, the clamping force compensating mechanism 60 can achieve the effect of balancing the clamping force through the cooperation of the assisting elastic member 61 and the triggering member 62, and has a simple structure and small occupied space.

Referring to fig. 9 to 11, in another embodiment, the base 10 is provided with a connecting shaft 50, the clamping force compensating mechanism 60 includes a second cam 63, a movable block 64 and an elastic restoring member 322, the second cam 63 is connected with the bracket assembly 20, the second cam 63 is rotatably sleeved on the connecting shaft 50, a boss 631 is provided on an axial end surface of the second cam 63, the boss 631 has a first flat surface 6311 and a first inclined surface 6312 that are adjacent to each other, the movable block 64 is slidably sleeved on the connecting shaft 50 in an axial direction, a protrusion 641 is provided on a side of the movable block 64 opposite to the second cam 63, the protrusion 641 has a second flat surface 6411 and a second inclined surface 6412 that are adjacent to each other, the elastic restoring member 322 is sleeved on the connecting shaft 50 and elastically abuts against a side of the movable block 64 facing away from the second cam 63, when an everting angle of the bracket assembly 20 is smaller than the preset angle, the first inclined surface 6312 is pressed and slides along the second inclined surface 6412 when the everting angle of the bracket assembly 20 is larger than the preset angle.

In this embodiment, when the everting angle of the temple 200 is smaller, the everting angle of the stand assembly 20 is smaller than the preset angle, and at this time, the stand assembly 20 is in press fit with the second inclined surface 6412 of the movable block 64 through the first inclined surface 6312 of the second cam 63, so that the elastic restoring member 322 generates compression deformation, and the elastic restoring member 322 acts on the movable block 64 in a reverse direction to provide a torsion output to the stand assembly 20, so as to generate an auxiliary clamping force, and the auxiliary clamping force increases with an increase of the compression deformation generated by the elastic restoring member 322. When the flip angle of the temple 200 is larger, the flip angle of the bracket assembly 20 is larger than the preset angle, and at this time, the bracket assembly 20 contacts the second plane 6411 of the movable block 64 through the first plane 6311 of the second cam 63, and no torque is provided, so that the auxiliary clamping force is removed. In this way, force value equalization of different angles of eversion can be achieved. It should be noted that the second cam 63 may be integrally connected to the bracket assembly 20 by welding or fastening, or the second cam 63 may be integrally formed with the bracket assembly 20, that is, the second cam 63 is formed as a part of the bracket assembly 20, for example, as shown in fig. 10, in this embodiment, the second cam 63 is integrally formed with the bracket assembly 20.

Alternatively, as shown in fig. 9, in an embodiment, the base 10 is provided with a connecting shaft 50, the homing booster mechanism 30 includes a first cam 31, a sliding block 321 and an elastic restoring member 322, the clamping force compensating mechanism 60 includes a second cam 63, a movable block 64 and an elastic restoring member 322, and the homing booster mechanism 30 and the clamping force compensating mechanism 60 may share one connecting shaft 50 and one elastic restoring member 322, so as to reduce the amount of parts and simplify the assembly process. For example, the upper and lower sides of the bracket assembly 20 are respectively provided with a first cam 31 and a second cam 63, the first cam 31 is rotatably sleeved at the upper end of the connecting shaft 50, and the second cam 63 is rotatably sleeved at the lower end of the connecting shaft 50, so that reliable rotation connection between the bracket assembly 20 and the connecting shaft 50 can be realized. The sliding block 321 and the movable block 64 are respectively and slidably sleeved on the connecting shaft 50, the sliding block 321 is close to the first cam 31, the movable block 64 is close to the second cam 63, the elastic resetting piece 322 is sleeved on the connecting shaft 50, one end of the elastic resetting piece 322 is elastically abutted with the sliding block 321, and the other end of the elastic resetting piece 322 is elastically abutted with the movable block 64, so that the whole structure is compact.

Referring to fig. 4 and 12, in one embodiment, the hinge module 100 further includes a housing 70, the housing 70 has a semi-enclosed structure with an opening at one side, the base 10 is connected to the opening side of the housing 70, and a wire passing space 701 is formed between the base 10 and the housing 70.

In the present embodiment, the base 10 and the housing 70 are connected and fixed by, but not limited to, a snap fit, a screw connection, etc. The main structures (e.g., the base 10 and the bracket assembly 20) of the hinge module 100 are uniformly arranged on the same side of the hinge module 100, so that a larger wire passing space 701 can be formed inside the housing 70 on the other side of the hinge module 100, thereby facilitating the signal wires 400 of the smart glasses 1000 to pass through and dissipate heat. Moreover, the base 10 can be used as a main body supporting structure to realize the supporting function of the bracket assembly 20, and on the other hand, one side of the base 10 away from the housing 70 can be used as an appearance surface of the hinge module 100, so that the overall appearance effect can be improved through a surface Physical Vapor Deposition (PVD) process.

Generally, as shown in fig. 20, the frame 300 of the smart glasses 1000 (such as AR glasses) includes a frame inner case 310 and a frame outer case 320 which are spliced with each other, and the temple 200 includes a temple inner case 210 and a temple outer case 220 which are spliced with each other, and when the temple 200 is fixed to the bracket assembly 20, only the inner side surface of the temple inner case 210 is required to be fixed to one side of the bracket assembly 20. However, as the requirements for the size, weight and appearance of AR products become higher, the internal space of many products is insufficient or there is no splice gap between the inner and outer shells, so that the integrally formed lens frame 300 and lens leg 200 are derived, and when the space limitation or the integrally formed lens frame 300 and lens leg 200 are fixed to the bracket assembly 20, the end surfaces of the lens leg 200 and lens frame 300 need to be fixed to the bracket assembly 20, and at this time, the bracket assembly 20 needs to be folded by a certain angle (for example, 90 °) to meet the installation requirement.

In order to enhance the versatility of the hinge module 100, as shown in fig. 13 to 16, in one embodiment, the stand assembly 20 includes a first cantilever 21 and a second cantilever 22, one side of the first cantilever 21 is rotatably connected to the base 10, the second cantilever 22 is movably connected to one side of the first cantilever 21 away from the base 10, the second cantilever 22 has an unfolded state (as shown in fig. 13) and a folded state (as shown in fig. 15) relative to the first cantilever 21, in the unfolded state, the second cantilever 22 forms a first preset included angle with the first cantilever 21 and remains fixed, and in the folded state, the second cantilever 22 forms a second preset included angle with the first cantilever 21 and remains fixed, and the first preset included angle is greater than the second preset included angle.

In this embodiment, by dividing the stand assembly 20 into two parts, i.e., the first cantilever 21 and the second cantilever 22, the angle between the first cantilever 21 and the second cantilever 22 can be adjusted, so that the stand assembly 20 can be fixed to the temple 200 or the frame 300 in two different fixing postures, so as to meet different application scenarios, thereby improving versatility. The first preset included angle and the second preset included angle can be set according to actual needs, and the first preset included angle is 180 degrees, and the second preset included angle is 90 degrees as an example. Taking the installation of the temple 200 as an example, as shown in fig. 13 and 14, when the first cantilever 21 is at the first preset angle relative to the second cantilever 22, the included angle between the first cantilever 21 and the second cantilever 22 is 180 ° and remains fixed, and at this time, the first cantilever 21 and the second cantilever 22 are flattened and remain fixed with each other, which can be well applied to a scene having the temple inner shell 210 and the temple outer shell 220 spliced with each other, and only one side of the second cantilever 22 needs to be fixed with the inner side surface of the temple inner shell 210. As shown in fig. 15 and 16, when the present invention is applied to a lens leg 200 (without a seam between the inner and outer shells of the lens leg 200) formed integrally or a scene where the space inside the lens leg 200 is insufficient, the second cantilever 22 is adjusted with respect to the first cantilever 21 so that the angle between the second cantilever 22 and the first cantilever 21 is 90 ° and kept fixed, and at this time, the second cantilever 22 is folded upright with respect to the first cantilever 21 and kept fixed, and then the end face of the lens leg 200 is directly fixed to the side face of the second cantilever 22. The mounting of the frame 300 and the bracket assembly 20 is similar to the temple 200 and will not be described in detail herein. In addition, the fixing manner between the temple 200 and the frame 300 and the stand assembly 20 includes, but is not limited to, screw connection, riveting, welding, clamping, etc.

When the folding state is to be adjusted, the clamping piece 24 is only required to be detached, the rotating shaft 23 is withdrawn and then the position is adjusted again and is inserted into the shaft hole 201, so that the convex key is clamped in the second key groove 203, and the clamping piece 24 is assembled. The angle adjustment between the second cantilever 22 and the first cantilever 21 is realized by adopting the structure, and the structure is simple and the operation is convenient.

In order to enable more reliable force transfer between second cantilever 22 and first cantilever 21, movement synchronicity of first cantilever 21 and second cantilever 22 is ensured while improving the overall structural strength of bracket assembly 20. In one embodiment, as shown in fig. 1, the second cantilever 22 is provided with a first protrusion 221 and a second protrusion 222, wherein in the unfolded state, the first protrusion 221 is engaged with the first cantilever 21 for force transmission, and in the folded state, the second protrusion 222 is engaged with the first cantilever 21 for force transmission.

In the folded state, the second protrusion 222 is in overlying engagement with the first cantilever 21, that is, the second protrusion 222 contacts the first cantilever 21 through a plane and limits the first cantilever 21, so that when the second cantilever 22 applies a force, the second protrusion 222 can transmit a moment to the first cantilever 21, so as to ensure that the first cantilever 21 and the second cantilever 22 can move synchronously.

In this way, the hinge module 100 is integrally provided with a biaxial layout, so that the bending radius can be increased, the signal wire 400 and the heat dissipation device are prevented from being broken due to the fact that the bending radius is too small, and the service lives of the signal wire 400 and the heat dissipation device of the intelligent glasses 1000 can be further prolonged.
