[0069] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0070] It should be noted that all the directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directionality indications will also change accordingly.

[0071] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three schemes, taking "A and / or B" as an example, including A scheme, or B scheme, or A and B schemes are satisfied at the same time.

[0072] In addition, the descriptions such as "first", "second" and the like in the present application are only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the technical features indicated or implicitly indicating the number of technical features. Therefore, the features defined as "first", "second" can be explicitly or implicitly included at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist, nor within the protection scope required by the present application.

[0073] At present, glasses usually adopt single-axis rotation for realizing folding of the temple, and facilitating storage. However, due to different head sizes of users, single-axis glasses will cause discomfort when worn, affecting the user's wearing and use. In particular, for virtual reality (VR), augmented reality (AR), mixed reality (MR) and extended reality (XR) glasses, even after wearing, the clarity of binocular image display will be affected.

[0074] In the related art, the rotation shaft of some glasses can realize folding of the temple while also having an eversion function, which is used to provide different head width sizes for users to wear, so as to improve the comfort of the glasses. However, for users with different head lengths, different head shapes, and different nose-ear distances, such single-axis eversion glasses still have the problem of discomfort when worn.

[0075] At the same time, in order to realize multi-axis rotation of the temple and the frame of the glasses, multiple single-axis structures are usually used to realize rotation of different axes, resulting in a relatively complex and dispersed hinge structure of the glasses, a relatively large structure volume, and a relatively cumbersome and complex disassembly of the entire glasses structure.

[0076] Based on the above ideas and problems, the present application proposes a hinge module 100, which can be applied to glasses 800. The glasses 800 can be myopia glasses, presbyopia glasses, astigmatism glasses, sun glasses and decorative glasses worn by people in daily life, and the glasses 800 can also be smart glasses, such as virtual reality (VR), augmented reality (AR), mixed reality (MR) and extended reality (XR) glasses, etc., which are not limited here.

[0077] In the embodiment, the glasses 800 include a frame 810 and a temple 820, and the temple 820 is connected with the frame 810 through the hinge module 100. The hinge module 100 is an integrated hinge structure, which can realize the hinged connection of the frame 810 and the temple 820, and facilitate the overall disassembly. It can be understood that the temple 820 of the glasses 800 is connected with the frame 810 through the hinge module 100, so that the glasses 800 can not only realize the folding storage, normal wearing and eversion function of the temple 820 relative to the frame 810, but also can realize the rotation adjustment of the temple 820 relative to the frame 810 in another direction, so that the glasses 800 can be suitable for users with different head lengths, different head shapes and different nose-ear distances, and the wearing comfort and universality of the user are improved.

[0078] Please refer to FIGS. 1-7, in the embodiment, the hinge module 100 includes a rotating base 1, a first connecting piece 2, a first elastic piece 3, a second connecting piece 4 and a second elastic piece 5. The rotating base 1 is provided with a receiving groove 11 and a first rotating hole 131, a second rotating hole 121 and a sliding hole 122 which are communicated with the receiving groove 11. The first connecting piece 2 is rotationally connected with the rotating base 1 through the first rotating shaft 24 matched with the hole shaft of the first rotating hole 131. One end of the first elastic piece 3 is accommodated in the receiving groove 11 and is provided with a damping groove 321 which rotationally abuts against the first rotating shaft 24. The other end of the first elastic piece 3 elastically abuts against the first connecting piece 2. The second connecting piece 4 is provided with a second rotating shaft 41 and a sliding shaft 42 which are arranged at intervals. The second rotating shaft 41 is rotationally arranged in the second rotating hole 121, so that the second connecting piece 4 is rotationally connected with the rotating base 1. The sliding shaft 42 is movably arranged in the sliding hole 122. The second elastic piece 5 is accommodated in the receiving groove 11 and elastically abuts against the sliding shaft 42. The axial direction of the first rotating shaft 24 and the axial direction of the second rotating shaft 41 are arranged at an angle.

[0079] In the embodiment, the hinge module 100 is provided with the rotating base 1, the first connecting piece 2 and the second connecting piece 4. The rotating base 1 is provided with the receiving groove 11 and the first rotating hole 131, the second rotating hole 121 and the sliding hole 122 which are communicated with the receiving groove 11. One end of the first connecting piece 2 is rotationally connected with the rotating base 1 through the first rotating shaft 24 matched with the hole shaft of the first rotating hole 131. The other end of the first connecting piece 2 is used for connecting with the temple 820. That is, the temple 820 is rotationally connected with the rotating base 1 through the first connecting piece 2 and the first rotating shaft 24. The second rotating shaft 41 of the second connecting piece 4 is rotationally arranged in the second rotating hole 121, and the sliding shaft 42 is movably arranged in the sliding hole 122, so that the rotating base 1 is rotationally connected with the second connecting piece 4. The second connecting piece 4 is used for connecting with the frame 810. In this way, the temple 820 is rotationally connected with the frame 810 through the hinge module 100.

[0080] It should be noted that, since the axial direction of the first rotating shaft 24 is arranged at an angle with the axial direction of the second rotating shaft 41, that is, the first connecting piece 2 of the hinge module 100 rotates around the axial direction of the first rotating shaft 24 relative to the rotating base 1, and the rotating base 1 rotates around the axial direction of the second rotating shaft 41 relative to the second connecting piece 4, so as to realize the multi-axial multi-degree-of-freedom rotation of the hinge module 100, so that the hinge module 100 is applied to the glasses 800, so that the glasses 800 can be suitable for users with different head lengths, different head shapes, and different nose-ear distances, improve the wearing comfort and universality of the user, that is, the temple 820 rotates around the axial direction of the first rotating shaft 24 relative to the rotating base 1 and the frame 810 through the first connecting piece 2, and the temple 820 rotates around the axial direction of the second rotating shaft 41 relative to the frame 810 through the rotating base 1, so as to realize that the temple 820 can rotate in multiple axial directions relative to the frame 810 with multiple degrees of freedom.

[0081] In the embodiment, one end of the first elastic member 3 is accommodated in the accommodation groove 11, and a damping groove 321 that rotates against the first rotating shaft 24 is arranged on the first elastic member 3, and the other end of the first elastic member 3 elastically abuts against the first connecting piece 2, so that in the process of rotating the first connecting piece 2 around the axial direction of the first rotating shaft 24 relative to the rotating base 1, the hinge module 100 utilizes the first elastic member 3 to form frictional damping in the rotating process, so that the first connecting piece 2 has a damping folding hand feeling in the movement process. The hinge movement, so as to realize the folding of the temple 820, and make the folding have a damping hand feeling and provide an eversion clamping force effect. At the same time, the second elastic member 5 is arranged in the accommodation groove 11 and elastically abuts against the sliding shaft 42, so that in the process of rotating the hinge module 100 around the axial direction of the second rotating shaft 41 relative to the second connecting piece 4 through the rotating base 1, the second elastic member 5 provides anti-deformation ability and prevents over-bending failure for the rotating base 1 rotating around the axial direction of the second rotating shaft 41.

[0082] The hinge module 100 of the present application is connected with the rotating base 1 through the first connecting piece 2 by the cooperation of the first rotating shaft 24 and the hole shaft of the first rotating hole 131, and the second connecting piece 4 is connected with the rotating base 1 by the second rotating shaft 41 and the sliding shaft 42, so that the second connecting piece 4 is connected with the rotating base 1, and the axial direction of the first rotating shaft 24 and the axial direction of the second rotating shaft 41 are arranged at an angle, so that the hinge module 100 can realize multi-axis rotation, that is, the hinge module 100 is rotated around the first rotating shaft 24 relative to the rotating base 1 through the first connecting piece 2, and the rotating base 1 is also rotated around the second rotating shaft 41 relative to the second connecting piece 4, that is, multi-degree-of-freedom rotation is realized, so that the hinge module 100 is applied to the glasses 800, so that the temple 820 of the glasses 800 is connected with the frame 810 through the hinge module 100, so that the temple 820 can be rotated around the first rotating shaft 24 relative to the rotating base 1 and the frame 810 through the first connecting piece 2, and the temple 820 can also be rotated around the second rotating shaft 41 relative to the frame 810 through the rotating base 1, that is, the temple 820 and the frame 810 can realize multi-degree-of-freedom rotation hinge through the multi-axis rotation of the hinge module 100, so that the glasses 800 is suitable for different head shapes of different users, such as different head lengths, different head shapes, and different nose-ear distances, to improve the wearing comfort and universality of the user; at the same time, one end of the first elastic piece 3 is accommodated in the accommodating groove 11, and a damping groove 321 is arranged on the first elastic piece 3 and rotationally abuts against the first rotating shaft 24, so that the other end of the first elastic piece 3 elastically abuts against the first connecting piece 2, so that when the first connecting piece 2 of the hinge module 100 is rotated around the first rotating shaft 24 relative to the rotating base 1, the first elastic piece 3 provides damping performance for the rotation of the first connecting piece 2, and the second elastic piece 5 is arranged in the accommodating groove 11 and elastically abuts against the sliding shaft 42, so that the second elastic piece 5 provides elastic limiting function and damping function for the rotation of the rotating base 1 relative to the second connecting piece 4, thereby providing different rotation angles.

[0083] In the present embodiment, the axial direction of the first rotating shaft 24 and the axial direction of the second rotating shaft 41 are optionally arranged vertically. It can be understood that when the user wears the glasses 800, the eyes of the user are taken as the light emitting direction as a reference, at this time, the light emitting direction, the axial direction of the first rotating shaft 24 and the axial direction of the second rotating shaft 41 are generally perpendicular to each other in a three-dimensional coordinate structure, that is, the axial direction of the first rotating shaft 24 and the light emitting direction are generally arranged vertically, and the axial direction of the second rotating shaft 41 and the light emitting direction are generally arranged vertically.

[0084] It should be noted that when the hinge module 100 is applied to the glasses 800, as shown in Figure 14, the glasses 800 has a folded state, an open state, and an outward-folding state in which the temples 820 rotate relative to the rotating base 1 and the frame 810 via the first connector 2 around the first pivot 24. Understandably, in the folded state, the temples 820 are close to the frame 810, that is, the temples 820 are roughly parallel to the frame 810, making the glasses 800 easy to store in the folded state. In the open state, the two temples 820 are roughly perpendicular to the frame 810. At this time, the two temples 820 and the frame 810 roughly enclose a U-shaped wearing cavity, which facilitates the two temples 820 to abut against the user's ears and, through the nose pads of the frame 810, abut against the user's nose bridge, thus achieving wearing. When the glasses 800 are in the outward-folded position, the two temples 820 are set at approximately an obtuse angle to the frame 810. At this time, the two temples 820 and the frame 810 roughly enclose to form a wide-mouthed U-shaped wearing cavity.

That is, when the glasses 800 is in the open state and the everted state, the temples 820 can rotate relative to the frame 810 about the second axis 41 in the initial position, the first position, and the second position, thus making it suitable for users with different head lengths and different nose-ear distances.

[0086] It should be noted that when the glasses 800 is in the open state, and the temples 820 are in their initial position, the extension direction of the temples 820 is consistent with the extension direction of the connecting or mounting portion of the frame 810; when the temples 820 are in the first or second position, the extension direction of the temples 820 forms a certain angle with the extension direction of the connecting or mounting portion of the frame 810. Optionally, the angle formed by the extension direction of the temples 820 and the extension direction of the connecting or mounting portion of the frame 810 is an acute angle.

[0146] The hinge module 100 mainly involves two degrees of freedom of rotation axes. The hinge module 100 is applied to the glasses 100, as shown in FIG. 10, the first rotation axis 24 (axis A) and as shown in FIG. 11 and FIG. 12, the second rotation axis 41 (axis B). The axis A is used to realize the folding function, the opening function and the eversion function of the temple 820. It can be understood that the folding function is used to realize the folding and storage of the temple 820, and the eversion function is used to satisfy the comfort adjustment of different head width users. The axis B is used to realize the lateral adjustment function of the temple 820, and the axis B has a three-grade adjustment function, which is used to satisfy the comfort adjustment of different head type and different nose-ear ratio users.

[0147] It can be understood that, as shown in FIG. 1 and FIG. 2, the first connecting member 2, the rotating base 1 and the first elastic member 3 are assembled together in advance as a whole module through the first rotation axis 24. Then, the second connecting member 4, the second elastic member 5, the protection plate 6 and the shell 7 are assembled in sequence.

[0148] The first connecting piece 2, the rotating base 1 and the first elastic piece 3 in the embodiment are assembled into a module structure through the first rotating shaft 24. The hinge module 100 passes through the second rotating hole 121 of the rotating base 1 through the second rotating shaft 41 of the second connecting piece 4, is connected and fixed with the fixing piece 44, and the second elastic piece 5 is elastically limited between the rotating cylinder 125 of the rotating base 1 and the sliding shaft 42. The first connecting piece 2 is rigidly connected to the glasses leg 820 through screwing, bonding and the like, and the second connecting piece 4 is connected with the glasses frame 810. The hinge module 100 is used to realize the shaft A movement of the glasses leg 820 and the eversion force value providing. After the hinge module 100 is assembled with the glasses frame 810 through the cooperation of the second connecting piece 4 and the second elastic piece 5, it is used to realize the lateral movement and force value providing (i.e. shaft B) of the glasses leg 820. As shown in FIGS. 10 and 14, the shaft A is used to realize the folding and eversion rotating movement. As shown in FIGS. 11, 12 and 13, the shaft B is used to realize the lateral shaft adjustment function of the glasses leg 820.

[0149] It can be understood that the glasses leg 820 and the glasses frame 810 of the glasses 800 can realize the hinge connection with the eversion and folding damping feeling. When the glasses leg 820 is rotated, the first connecting piece 2 is rotated. The rotating base 1 is fixed with the glasses frame 810 through the second connecting piece 4. The first elastic piece 3 is a metal plate with good elasticity. The eversion elastic piece 311 on the first elastic piece 3 is used to provide the clamping force during eversion and the automatic rebound after the eversion force is removed. The damping groove 321 of the damping branch 32 of the first elastic piece 3 is used to provide the damping force during the rotating process of the glasses leg 820, so that there is a certain damping feeling in the movement process. The first rotating shaft 24 is a pin shaft with different sections. The two ends are flat shafts, which are used to be rigidly fixed with the first connecting piece 2, for example, through interference, spot welding, bonding and the like. The fixing of the first rotating shaft 24 and the rotating base 1 is a circular hole cylindrical cooperation, which forms the rotating center shaft A and is used for the mutual rotation of the two. Therefore, when the glasses leg 820 is folded, the glasses leg 820 drives the first connecting piece 2 inward, and the folding movement is formed through the first rotating shaft 24 and the rotating base 1. The first rotating shaft 24 rotates together with the first connecting piece 2. The rotation of the first rotating shaft 24 forms the friction damping with the damping groove 321 of the first elastic piece 3, so that the hinge movement with the damping folding hand feeling is obtained in the movement process, thereby realizing the folding of the glasses leg 820 and making the folding have the damping hand feeling.

[0150] When the temple 820 is out-turned, the temple 820 will drive the first connecting piece 2 to rotate outward to meet the wearing of users with different head widths, and the rotating first connecting piece 2 will drive the out-turned elastic sheet 311 on the first elastic piece 3 to elastically deform, thereby generating a torque to push the first connecting piece 2 to rotate inward, thereby providing a holding force. After the out-turned external force is removed, the elastically deformed out-turned elastic sheet 311 will push the first connecting piece 2 to drive the temple 820 to return to the original state of the elastic sheet, thereby realizing that the temple 820 can automatically rebound to the original position after the out-turned force is removed.

[0151] It can be understood that the temple 820 and the frame 810 of the glasses 800 can also realize a structure scheme of lateral shaft adjustment, which is used to realize the angle adjustment between the temple 820 and the frame 810 to meet the wearing of users with different head types. After the hinge module 100 passes through the positioning groove of the frame 810, the second connecting piece 4 is positioned and limited with the corresponding groove of the frame 810 through the fastener 830, and is fixed. Since the second rotating shaft 41 of the second connecting piece 4 in the hinge module 100 and the second rotating hole 121 in the rotating base 1 cooperate to form a rotating shaft, the rotating center shaft B is composed of the lateral direction, when the temple 820 is rotated in the upward and downward directions, the temple 820 drives the hinge module 100 to rotate along the rotating center shaft B. When the first sliding shaft 421 cooperates with the arc-shaped groove 511, the cylinder of the first sliding shaft 421 is in interference contact with the elastic groove of the arc-shaped groove 511, and the temple 820 is maintained in the initial position. When the temple 820 is rotated downward, the cylinder of the first sliding shaft 421 is separated from the arc-shaped groove 511. When it is continuously rotated to a predetermined angle, such as 10 degrees, the cylinder of the third sliding shaft 423 will be elastically pressed into the groove of the second limiting groove 532, and the second limiting groove 532 will limit the third sliding shaft 423. The temple 820 stays in the second position state of rotating downward by 10 degrees, thereby completing the lateral downward attitude adjustment of the temple 820. Similarly, the second sliding shaft 422 and the first limiting groove 522 complete the upward angle adjustment, so that the temple 820 stays in the first position state of rotating upward, and the angle adjustment of the temple 820 and the frame 810 is completed. The rotated schematic diagram is shown in FIGS. 12 and 13.

[0152] The sliding shaft 42 can slide in the corresponding sliding hole 122 on the rotating base 1, which can enhance the anti-deformation ability when the temple 820 is twisted, and prevent the problem of over-bending failure. The material of the second elastic piece 5 can be stainless steel material, including titanium alloy, nickel-titanium alloy, beryllium copper and other materials; or the material of the second elastic piece 5 can also be carbon fiber composite material.

Of course, in other embodiments, the frame 810 can also be connected with a head-wearing structure to form an annular wearing space with the frame 810, etc., especially for smart glasses devices, because the frame 810 is provided with an optical system, which makes the frame 810 as a whole relatively heavy. In order to facilitate wearing and avoid the frame 810 from falling due to its relatively large weight, a head-wearing structure or a headband structure is designed, which is not limited here.

[0157] In the present embodiment, the pair of glasses 800 is taken as an example in which the frame 810 cooperates with the two temples 820.
