Detailed implementation manners

[0045] In order to make the above objects, features, and advantages of the present application more obvious and understandable, the following provides a detailed description of the specific embodiments of the present application with reference to the accompanying drawings.

[0046] In the following description, specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0047] Please refer to Figures 1 to 18 。

[0048] A specific embodiment of the present application provides a hinge applied to AR glasses. The hinge includes: a housing 1, a first torsion arm 2, a second torsion arm 3, and an elastic member. An arc-shaped slideway 13 is provided inside the housing 1. One end of the first torsion arm 2 is provided with a first connection portion 21 located outside the housing 1, and the other end is provided with a first arc-shaped slider 22 slidably connected to the arc-shaped slideway 13. The first arc-shaped slider 22 can rotate relative to the arc-shaped slideway 13. One end of the second torsion arm 3 is provided with a second connection portion 31 located outside the housing 1, and the other end is provided with a second arc-shaped slider 32 slidably connected to the arc-shaped slideway 13. The second arc-shaped slider 32 can rotate relative to the arc-shaped slideway 13. The elastic member is located in the arc-shaped slideway 13. When the first arc-shaped slider 22 and the second arc-shaped slider 32 rotate towards each other, that is, when the hinge is unfolded, the elastic member presses against the first torsion arm 2 and the second torsion arm 3. After being compressed, the elastic member can exert a certain elastic force on the first torsion arm 2 and the second torsion arm 3, which can play a certain buffering role during unfolding to prevent the first torsion arm 2 and the second torsion arm 3 from rigidly colliding. Secondly, through the mutual cooperation of the arc-shaped slideway 13 and the arc-shaped slider, the connection stability of the hinge can be improved. When the hinge is folded, the first torsion arm 2 and the second torsion arm 3 are not affected by the elastic force of the elastic member. When the hinge is connected to the temple 02 and the frame 01, when the two temples 02 are unfolded, the two temples 02 can maintain a certain clamping force under the action of the elastic force, thereby increasing the wearing applicability and comfort.

[0049] In some embodiments of the present application, please refer to Figures 2 to 6, the hinge further includes a gear 142, a disc spring 143 and a fastener. The fastener sequentially passes through the gear 142 and the disc spring 143 and is fixed in the arc-shaped slideway 13. The fastener is preferably an adjusting screw 144; racks are provided on the upper and lower opposite end faces of the first arc-shaped slider 22 and the second arc-shaped slider 32, and the racks are engaged with the gear 142. By controlling the screwing depth of the adjusting screw 144, the damping force when the gear 142 rotates can be adjusted, that is, the deeper the adjusting screw 144 is screwed in, the greater the damping force of the gear 142, and at this time, the greater the resistance of the first arc-shaped slider 22 and the second arc-shaped slider 32 to rotate. Through the cooperation of the gear 142 and the rack, the feel of the user when folding the hinge can be improved, and thus the use experience effect can be enhanced.

[0050] In some embodiments of the present application, a first arc-shaped limiting groove 1110 and a second arc-shaped limiting groove 1111 are provided on the inner wall of the arc-shaped slideway 13. A first limiting block 221 is provided on the first arc-shaped slider 22, and the first limiting block 221 is slidably connected to the first arc-shaped limiting groove 1110. A second limiting block 321 is provided on the second arc-shaped slider 32, and the second limiting block 321 is slidably connected to the second arc-shaped limiting groove 1111. When the first limiting block 221 contacts one end of the first arc-shaped limiting groove 1110 and the second limiting block 321 contacts one end of the second arc-shaped limiting groove 1111, the relative rotation movement of the first torsion arm 2 and the second torsion arm 3 can be restricted, thereby avoiding the problem of damaging the hinge.

[0051] In some embodiments of the present application, please refer to Figures 3 to 5 , one end of the first torsion arm 2 facing the second torsion arm 3 is provided with a first arc-shaped slider 22, and one end of the second torsion arm 3 facing the first torsion arm 2 is provided with two second arc-shaped sliders 32. The first arc-shaped slider 22 is located between the two second arc-shaped sliders 32. Racks are provided on the upper and lower end faces of the first arc-shaped slider 22 and the opposite end faces of the two second arc-shaped sliders 32. Two gears 142 are provided in the arc-shaped slideway 13. One of the gears 142 is respectively engaged with the rack on the upper end of the first arc-shaped slider 22 and the rack on the lower end of the upper second arc-shaped slider 32, and the other gear 142 is respectively engaged with the rack on the lower end of the first arc-shaped slider 22 and the rack on the upper end of the lower second arc-shaped slider 32. The rack on the first arc-shaped slider 22 is denoted as the first meshing tooth 224, and the rack on the second arc-shaped slider 32 is denoted as the second meshing tooth 324. The upper gear 142 is respectively engaged with the first meshing tooth 224 on the upper end face of the first arc-shaped slider 22 and the second meshing tooth 324 on the lower end face of the upper second arc-shaped slider 32, and the lower gear 142 is respectively engaged with the first meshing tooth 224 on the lower end face of the first arc-shaped slider 22 and the second meshing tooth 324 on the upper end face of the lower second arc-shaped slider 32. Through the two groups of gear 142 and rack meshing structures, the smoothness of the rotation of the first torsion arm 2 and the second torsion arm 3 can be improved.

[0052] In some embodiments of the present application, please refer to Figure 4 and Figure 5 , the elastic member includes a first spring 223 and a second spring 323. One end of the first spring 223 is fixedly connected to one end of the first arc-shaped slider 22 away from the first connecting portion 21, and the other end of the first spring 223 corresponds to the end surface of the second connecting portion 31 close to the second arc-shaped slider 32. A first positioning post 222 can be provided on the first arc-shaped slider 22, and the first spring 223 is sleeved on the first positioning post 222, and the length of the first spring 223 is longer than that of the first positioning post 222; one end of the second spring 323 is fixedly connected to one end of the second arc-shaped slider 32 away from the second connecting portion 31, and the other end of the second spring 323 corresponds to the end surface of the first connecting portion 21 close to the first arc-shaped slider 22. A second positioning post 322 can be provided on the second arc-shaped slider 32, and the second spring 323 is sleeved on the second positioning post 322, and the length of the second spring 323 is longer than that of the second positioning post 322. The first spring 223 and the second spring 323 can improve the uniformity of the force on the first torsion arm 2 and the second torsion arm 3. Through the first positioning post 222 and the second positioning post 322, a certain guiding effect can be exerted on the first spring 223 and the second spring 323 during expansion and contraction, thereby ensuring the stability of expansion and contraction.

[0053] In some embodiments of the present application, as Figure 7 and Figure 8 shown, two groups of parallel limiting ribs 1112 are provided in the housing 1. The first arc-shaped slider 22 is located between the two groups of limiting ribs 1112. Each group of limiting ribs 1112 includes two arc-shaped protrusions located on the same horizontal plane and spaced apart from each other. The space between the two arc-shaped protrusions is used to avoid the meshing connection of the gear 142 and the rack. The limiting ribs 1112 can play an axial limiting role on the first arc-shaped slider 22. Combining with the circumferential torsion limiting effect of the first arc-shaped limiting groove 1110 and the first limiting block 221, the stability of the connection of the first arc-shaped block in the housing 1 can be effectively ensured.

[0054] In some embodiments of the present application, as Figure 1 and Figure 2As shown in the figure, the housing 1 includes a fixed cover 11 and a fixed arm 12. The fixed cover 11 includes an arc plate 111. At the upper and lower ends of the arc plate 111, sector plates 112 extending in the horizontal direction are respectively provided. The upper and lower ends of the fixed arm 12 are respectively connected to the two sector plates 112. Installation holes 1121 can be provided on the sector plates 112, and fixing screws 141 can pass through the installation holes 1121 and be tightened in the fixing holes 146 on the fixed arm 12. On the opposite sides of the fixed arm 12 and the arc plate 111, arc surfaces for forming an arc slideway 13 are provided. On the arc surface side of the fixed arm 12, a threaded hole 145 for connecting an adjusting screw 144 is provided. The cross-section of the arc plate 111 is C-shaped, and the cross-section of the fixed arm 12 is D-shaped.

[0055] In some embodiments of the present application, as Figure 9 shown in the figure, the housing 1 further includes a cover plate 14. The two ends of the cover plate 14 are respectively connected to the two sector plates 112. For example, connection can be achieved through a buckle 16. Specifically, hooks 1122 can be respectively provided on the two sector plates 112, and clamping grooves that cooperate with the hooks 1122 are respectively provided at the upper and lower end portions of the cover plate 14. The cover plate 14 and the arc plate 111 are located on different sides of the fixed arm 12. A wire threading channel 15 is provided between the cover plate 14 and the fixed arm 12. The flexible circuit board / flexible heat-conducting material 4 can pass through the wire threading channel 15. That is, there are two channels in the housing 1. One is the arc slideway 13, and the other is the wire threading channel 15. The two are separated by the fixed arm 12 and do not affect each other. When the hinge is folded around the rotation center A, due to the cover plate 14 having a certain width b, it can ensure that the flexible circuit board / flexible heat-conducting material 4 has a large bending radius, thereby improving the service life of the flexible circuit board / flexible heat-conducting material 4. In addition, the flexible circuit board / flexible heat-conducting material 4 can be shielded by the cover plate 14 to prevent it from being easily damaged due to being exposed. Further, the side surface of the cover plate 14 away from the fixed arm 12 is an arc surface, and the axis of the arc surface is parallel to the axis of the sector plate 112. The arc surface is in contact with the inner side surfaces of the spectacle frame 01 and the temple 02 respectively.

[0056] Please refer to Figures 10 to 12 , Figure 10 shows that the first torsion arm 2 and the second torsion arm 3 have a certain preloading angle B under the action of the first spring 223 and the second spring 323. Figure 11 shows the state when the first torsion arm 2 and the second torsion arm 3 are in the unfolded state. Figure 12 shows that the first torsion arm 2 and the second torsion arm 3 have a certain outward turning angle C under the action of the first limiting block 221 and the second limiting block 321. It can be seen from this that the hinge has a certain range of bending angles and can be adapted to the needs of different users.

[0057] An embodiment of the present application further provides an AR glasses. Please refer toFigures 13 to 18 , including a frame 01 and temple arms 02, and further including the hinge provided in any of the above embodiments. The frame 01 is connected to the first connecting portion 21, and the temple arms 02 are connected to the second connecting portion 31. Wherein the frame 01 and the temple arms 02 are respectively of a hollow structure, and the first connecting portion 21 and the second connecting portion 31 can be connected to the inside of the frame 01 and the temple arms 02 by screws. An avoidance inclined surface 03 is provided on the inner side of the opposite ends of the temple arms 02 and the frame 01, and this avoidance inclined surface 03 contacts the arc surface on the outer side of the cover plate 14, which can ensure the smoothness when the temple arms 02 are folded.
