[0041] In the description of the present application, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, in the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0042] An embodiment of the present invention provides a spectacle hinge 1 for rotatably connecting a spectacle frame 60 and temple 70. The spectacle hinge 1 can be applied to both conventional optical vision correction spectacles and scenarios such as eye protection and smart glasses. Refer to Figures 1-9 , in the embodiment of the present invention, the spectacle hinge 1 includes a first mounting seat 10, a second mounting seat 30, and an elastic component 20. The first mounting seat 10 has an end plate 11, the end plate 11 has a first end face 111 and a second end face 112 disposed opposite to each other along the thickness direction of the end plate 11, the end plate 11 further has a first mounting hole 113, and the first mounting hole 113 penetrates through the first end face 111 and the second end face 112. The elastic component 20 includes a pull rod 21 and an elastic member 22. The pull rod 21 passes through the first mounting hole 113 and extends to both sides of the end plate 11. The pull rod 21 has a first connection end 211 and a second connection end 212 disposed opposite to each other along the length direction of the first mounting hole 113. The first connection end 211 is disposed on the side corresponding to the first end face 111 and protrudes from the first end face 111, the second connection end 212 is disposed on the side corresponding to the second end face 112 and protrudes from the second end face 112. The elastic member 22 is disposed on the side of the end plate 11 facing away from the first mounting seat 10 and elastically connects the pull rod 21 and the first mounting seat 10. The size of the first connection end 211 is larger than that of the first mounting hole 113 to prevent the first connection end 211 from passing through the first mounting hole 113. The second mounting seat 30 is disposed opposite to the first end face 111 of the end plate 11 and is rotatably connected to the first connection end 211. The rotation axis of the second mounting seat 30 relative to the first connection end 211 is the first rotation axis AX, and the first rotation axis AX is perpendicular to the first mounting hole 113. It should be understood that in the embodiment of the present invention, the "first rotation axis AX" is an abstract concept used to represent the rotation axis of the relative rotation between the second mounting seat 30 and the first connection end 211, and does not indicate that the rotational connection between the second mounting seat 30 and the first connection end 211 can only be realized by an "axis" structure. The rotational connection between the second mounting seat 30 and the first connection end 211 can also be realized by a connection structure other than an "axis". Refer to Figure 9 and Figure 10 , when the spectacle hinge 1 is installed on the spectacle, the first mounting seat 10 is installed on one of the spectacle frame 60 and the temple 70, and the second mounting seat 30 is installed on the other of the spectacle frame 60 and the temple 70. Thus, the temple 70 can rotate relative to the spectacle frame 60 around the first rotation axis AX to realize the unfolding and folding of the spectacle. For example, in the embodiment of the present invention, the first mounting seat 10 is connected to the spectacle frame 60, and the second mounting seat 30 is connected to the temple 70.

[0043] In some embodiments, refer to Figures 3-9, the first mounting seat 10 further includes a first connecting plate 12. The first connecting plate 12 is connected to the end plate 11 and has a first fixing structure 121 for connecting with the spectacle frame 60. For example, the first fixing structure 121 can be a hole, and the connection between the first mounting seat 10 and the spectacle frame 60 can be achieved by passing a fastener through the first fixing structure 121 and the spectacle frame 60. Optionally, the first connecting plate 12 can be substantially perpendicular to the end plate 11. The second mounting seat 30 has a second connecting plate 33. The second connecting plate 33 is substantially perpendicular to the third end face 311 and has a second fixing structure 331 for connecting with the temple 70. For example, the second fixing structure 331 can be a hole. Optionally, a detachable member 90 can be provided between the second mounting seat 30 and the temple 70 to facilitate the disassembly and assembly between the spectacle hinge 1 and the temple 70. The detachable member 90 is fixed in the temple 70, and the second mounting seat 30 can be fixed to the temple 70 by connecting the second mounting seat 30 with the detachable member 90.

[0044] In an embodiment of the present invention, the side surface of the second mounting seat 30 further has a cam surface 31. When the second mounting seat 30 rotates around the first rotating shaft AX relative to the first connection end 211, the contact position between the cam surface 31 and the first end face 111 also changes accordingly, so that the distance between the first connection end 211 and the first end face 111 changes, driving the pull rod 21 to move along the first mounting hole 113. The elastic member 22 is elastically connected between the second end face 112 and the second connection end 212 to keep the cam surface 31 in abutment with the first end face 111. Thus, when the user rotates the temple 70 relative to the spectacle frame 60, the elastic force of the elastic member 22 is transmitted to the temple 70 through the pull rod 21 and the second mounting seat 30, providing a tactile feedback to the user.

[0045] The elastic member 22 can be a spring piece, a spring, an elastic block, a gas spring or other elastic structures or materials. In one embodiment, the elastic member 22 includes a spring. The second connection end 212 has a first external thread section 2121. The elastic assembly 20 further includes a nut 23. The nut 23 is screwed onto the first external thread section 2121. The spring is sleeved outside the pull rod 21 and abuts between the nut 23 and the second end face 112, realizing the elastic floating connection between the pull rod 21 and the first mounting seat 10. By adjusting the screwing position of the nut 23 on the first external thread section 2121, the initial compression amount of the spring can be adjusted, thereby adjusting the tactile feedback force provided to the user.

[0046] In one embodiment, refer to Figures 5-8, the cam surface 31 includes a third end face 311, a fourth end face 312, and a transition surface 313 connecting between the third end face 311 and the fourth end face 312. A predetermined angle is formed between the third end face 311 and the fourth end face 312, and the distance between the transition surface 313 and the first rotating shaft AX is greater than the distance between the third end face 311 and the first rotating shaft AX and greater than the distance between the fourth end face 312 and the first rotating shaft AX. That is, when the transition surface 313 contacts the first end face 111 (refer to Figure 7 ), the distance between the first rotating shaft AX or the first connecting end 211 and the first end face 111 is greater than the distance when the third end face 311 contacts the first end face 111 (refer to Figure 5 ) or when the fourth end face 312 contacts the first end face 111 (refer to Figure 6 ), and the compression amount of the elastic member 22 is also larger. In one embodiment, the distance between the third end face 311 and the first rotating shaft AX may be substantially equal to the distance between the fourth end face 312 and the first rotating shaft AX, and the angle between the third end face 311 and the fourth end face 312 may be substantially equal to 90°. The third end face 311 and the fourth end face 312 may be flat surfaces, and the transition surface 313 may be formed as an arc surface.

[0047] After the first mounting seat 10 and the second mounting seat 30 are respectively connected to the spectacle frame 60 and the temple 70, when the temple 70 is folded relative to the spectacle frame 60, the fourth end face 312 abuts against the first end face 111 (as shown in Figure 6 ); when the temple 70 is unfolded relative to the spectacle frame 60, the third end face 311 abuts against the first end face 111 (as shown in Figure 5 ). When the temple 70 rotates from the folded state to the unfolded state (the rotation direction is counterclockwise in the figure), the distance between the first connecting end 211 and the first end face 111 gradually increases until the transition surface 313 abuts against the first end face 111 (as shown in Figure 7 ), at which time the distance between the first connecting end 211 and the first end face 111 is the largest and the compression amount of the elastic member 22 is also the largest. If the second mounting seat 30 is released before the transition surface 313 abuts against the first end face 111, the pull rod 21 and the second mounting seat 30 will reset under the elastic force of the elastic member 22, and the second mounting seat 30 will return to the state where the fourth end face 312 abuts against the first end face 111. After the second mounting seat 30 continues to rotate counterclockwise beyond the position shown in Figure 7 , the distance between the first connecting end 211 and the first end face 111 gradually decreases until the third end face 311 abuts against the first end face 111. During this process, the elastic force of the elastic member 22 can promote the counterclockwise rotation of the second mounting seat 30 and ensure that the third end face 311 can abut against the first end face 111 so that the temple 70 can be unfolded in place. Similarly, during the process of folding the temple 70 from the unfolded state, the second mounting seat 30 moves from Figure 5Rotate clockwise around the first rotating shaft AX in the figure from the shown position, and after passing through Figure 7 the shown position, the elastic force of the elastic member 22 can promote the second mounting seat 30 to continue rotating clockwise, ensuring that the fourth end face 312 can abut against the first end face 111, so that the temple 70 can be folded in place.

[0048] In some cases, for example, when the user wears glasses, it may be necessary to expand the temple 70 outward by a certain angle to facilitate wearing the glasses on the head. At this time, rotate the second mounting seat 30 from Figure 5 the position along the counterclockwise direction around the first rotating shaft AX in the figure. The second mounting seat 30 can still rotate a certain angle (for example, Figure 8 the position shown in). During this process, the included angle between the third end face 311 and the first end face 111 increases, the pull rod 21 is pulled out to the right in the figure, and the compression amount of the elastic member 22 increases; when the temple 70 is released, the second mounting seat 30 and the pull rod 21 automatically reset under the action of the elastic force of the elastic member 22, ensuring that the temple 70 can reset and automatically fit the user's head after the user wears the glasses.

[0049] In one embodiment, referring to Figures 1-3 , the end plate 11 has two first mounting holes 113 arranged at intervals, the number of the elastic components 20 is two, and each first mounting hole 113 is provided with a corresponding elastic component 20. The pull rods 21 of the two elastic components 20 are substantially parallel to each other. The second mounting seat 30 has two shaft mounting portions 32 arranged at intervals, and each shaft mounting portion 32 is connected to a corresponding elastic component 20, that is, the first connection end 211 of each pull rod 21 is connected to a corresponding shaft mounting portion 32. By providing two elastic components 20, it is beneficial to enhance the stability of the spectacle hinge 1 to ensure the stable connection between the temple 70 and the spectacle frame 60.

[0050] Figures 11-13 They are respectively Figure 4 the cross-sectional schematic views of the B-B plane, C-C plane and D-D plane in, Figure 14 is Figure 5 the cross-sectional schematic view of the E-E plane in. Referring to Figure 3 , Figures 11-14, the first connection end 211 is disposed between two shaft mounting portions 32. The end plate 11 has a first wire groove 114 penetrating through the first end face 111 and the second end face 112, and the first wire groove 114 is disposed between two first mounting holes 113. The spectacle hinge 1 further includes a sleeve 40, which is disposed between two shaft mounting portions 32 and at least partially surrounds the first rotating shaft AX. The side wall of the sleeve 40 has a second wire groove 41, and the second wire groove 41 communicates with the first wire groove 114. In some application scenarios, when there is a circuit in the spectacle, it is necessary to thread a wire 80 between the spectacle frame 60 and the temple 70. The wire 80 can pass through the first wire groove 114 and the second wire groove 41 to achieve wiring between the spectacle frame 60 and the temple 70, and the wire 80 can be threaded between two connecting rods 21. The sleeve 40 can also shield the wire 80. When the temple 70 rotates relative to the spectacle frame 60, the sleeve 40 shields the outside of the wire 80 to prevent the wire 80 from being exposed, which is beneficial to improving the aesthetics and preventing the wire 80 from being damaged.

[0051] In one embodiment, the first wire groove 114 has a first opening 115 on the side of the end plate 11, and the second wire groove 41 has a second opening 42. Refer to Figure 12 , when threading the wire 80, it can be placed into the first wire groove 114 through the first opening 115 and into the second wire groove 41 through the second opening 42, which is convenient for threading the wire 80. Preferably, the opening directions of the first opening 115 and the second opening 42 are different, which can prevent the wire 80 from coming out. For example, refer to Figure 3 , the first opening 115 is opened on the front side of the end plate 11, and the second opening 42 is opened at the upper end of the sleeve 40. After the sleeve 40 is connected to the second mounting seat 30, the shaft mounting portion 32 shields the second opening 42.

[0052] Optionally, the side surface of the sleeve 40 abuts against the first end face 111 to prevent the sleeve 40 from rotating relative to the first mounting seat 10. Optionally, the first connection end 211 has a first circumferential limiting structure 2111, and the sleeve 40 has a second circumferential limiting structure 44. The first circumferential limiting structure 2111 cooperates with the second circumferential limiting structure 44 to limit the rotation of the first connection end 211 around the first rotating shaft AX, ensuring the stability of the movement of the connecting rod 21. For example, refer to Figure 3 , Figure 11 and Figure 15 , the first circumferential limiting structure 2111 can be a convex block, and the second circumferential limiting structure 44 is a groove on the sleeve 40 corresponding to the convex block. In some embodiments, refer to Figure 13 and Figure 15 , the sleeve 40 further has a mounting groove 43 for accommodating the first connection end 211. The mounting groove 43 can position the first connection end 211 and can also play a certain role in isolating the threading path of the wire 80 from the first connection end 211.

[0053] Referring to Figure 3 、 Figure 9 、 Figures 11-14 ,the spectacle hinge 1 further includes a connecting member 50, and the second mounting seat 30 and the first connection end 211 are rotationally connected through the connecting member 50. The connecting member 50 can be any structure that can achieve the rotational connection between the second mounting seat 30 and the first connection end 211. Optionally, in some embodiments, the shaft mounting portion 32 has a second mounting hole 321, and the first connection end 211 has a third mounting hole 2112. The connecting member 50 can be, for example, a pin, a screw, etc. By passing the connecting member 50 through the second mounting hole 321 and the third mounting hole 2112, the rotational connection between the second mounting seat 30 and the first connection end 211 can be achieved, and the first rotating shaft AX is the axis of the connecting member 50.

[0054] In one embodiment, referring to Figure 3 、 Figures 13-14 ,the connecting member 50 has a second external thread section 51 and a smooth shaft section 52 arranged in sequence along the extension direction of the first rotating shaft AX. The second mounting hole 321 has an internal thread corresponding to the first external thread section 2121. The second external thread section 51 is connected to the second mounting hole 321, and the smooth shaft section 52 passes through the third mounting hole 2112, so that the connecting member 50 is relatively fixed to the second mounting seat 30, and the second mounting seat 30 is smoothly rotationally connected to the first connection end 211 through the smooth shaft section 52.

[0055] In another embodiment, referring to Figure 9 and Figure 16 ,the connecting member 50 can be a pin, and the same connecting member 50 can pass through two shaft mounting portions 32 and two first connection ends 211 to achieve the rotational connection between the second mounting seat 30 and the first connection end 211. The wire 80 can be drawn through the outside of the connecting member 50.

[0056] In another embodiment, referring to Figure 17 ,the shaft mounting portion 32 includes two connecting ears 322, and the two connecting ears 322 are spaced apart along the extension direction of the first rotating shaft AX. Each connecting ear 322 has a second mounting hole 321 respectively, and the first connection end 211 is arranged between the two connecting ears 322. The connecting member 50 passes through the second mounting holes 321 and the third mounting holes 2112 of the two connecting ears 322 to connect the first connection end 211 and the second mounting bracket.
