[0039] As shown in Figure 1 and Figure 2 The hinge structure 100 provided by the embodiments of the present application is applied to glasses, and includes a first connecting piece 10 and a second connecting piece 20. The first connecting piece 10 and the second connecting piece 20 are rotationally connected. The first connecting piece 10 is used to connect a frame, and the second connecting piece 20 is used to connect a leg. The folding and unfolding of the leg relative to the frame is realized by the rotation of the second connecting piece 20 relative to the first connecting piece 10.

[0040] The first connecting piece 10 includes a first mounting plate 11 and a rotating shaft 12 connected with each other. The first mounting plate 11 is used to be fixedly connected with the frame. The second connecting piece 20 includes a second mounting plate 21 and a rotating piece 22 connected with each other. The second mounting plate 21 is used to be fixedly connected with the leg. The rotating piece 22 is rotatably sleeved on the rotating shaft 12, so as to realize the rotational connection between the first connecting piece 10 and the second connecting piece 20.

[0041] The rotating shaft 12 has a first arc surface 121, a first limiting surface 122, a second limiting surface 123, and a second arc surface 124. The second arc surface 124 is arranged between the first limiting surface 122 and the second limiting surface 123. The rotating member 22 includes an arc portion 221 and a bent portion 222 connected to each other. When the rotating shaft 12 is assembled with the bent portion 222, the arc portion 221 is tightly connected with the first arc surface 121, and the bent portion 222 is assembled with the rotating shaft 12 between the first limiting surface 122 and the second limiting surface 123.

[0042] The hinge structure 100 can rotate the second connecting member 20 relative to the first connecting member 10, so as to realize folding and unfolding of the glasses legs relative to the glasses frame. During rotation of the rotating member 22 around the rotating shaft 12, the bent portion 222 can be arranged in the first limiting surface 122, so that the end of the first limiting surface 122 abuts against the bent portion 222, the bent portion 222 is elastically deformed, the rotating shaft 12 and the rotating member 22 can be kept in a relatively stable state at the rotating position, and the first connecting member 10 can be kept in a relatively stable state relative to the second connecting member 20.

[0043] Similarly, during rotation of the rotating member 22 around the rotating shaft 12, the bent portion 222 can also be arranged in the second limiting surface 123, so that the end of the second limiting surface 123 abuts against the bent portion 222, the bent portion 222 is elastically deformed, the rotating shaft 12 and the rotating member 22 can be kept in a relatively stable state at the rotating position, and the first connecting member 10 can be kept in a relatively stable state relative to the second connecting member 20. In the present application, the hinge structure 100 can keep the second connecting member 20 in a stable state at different rotating positions during rotation relative to the first connecting member 10, so as to keep the glasses legs in a stable state at a required position relative to the glasses frame, thereby improving the user experience.

[0044] Specifically, as shown in Figure 1 One end of the arc portion 221 is connected to the second mounting plate 21, and the other end of the arc portion 221 is bent to form the bent portion 222. The bent portion 222 includes a non-free end 227 connected to the arc portion 221 and a free end 228 away from the arc portion 221.

[0045] In the folded assembly state of the first connecting piece 10 and the second connecting piece 20, the arc-shaped portion 221 and the first arc-shaped surface 121 are tightly connected, the first limiting surface 122 is arranged to be inclined along the length direction of the first mounting plate 11 to the side away from the second connecting piece 20, the bending portion 222 is arranged to extend along the direction perpendicular to the length direction of the second mounting plate 21, and the bending portion 222 partially abuts against the first limiting surface 122. Thus, in the folded assembly state, there is an angle difference between the first limiting surface 122 and the inner surface of the bending portion 222, the end adjacent to the first limiting surface 122 and the second arc-shaped surface 124 abuts against the free end 228 of the bending portion 222, and the end adjacent to the first arc-shaped surface 121 and the non-free end 227 of the bending portion 222 are separated or connected without pressure. At this time, the bending portion 222 is elastically deformed under the abutting action of the first arc-shaped surface 121 to generate a locking force, so that the rotating shaft 12 and the rotating piece 22 can be kept in a relatively stable state at this position.

[0046] Specifically, referring to Figures 1-2 , the placement state of the first connecting piece 10 perpendicular to the paper surface direction is taken as a reference position, and the positions and structural relationships of other components are described. Figure 1 In the first connecting piece 10, the state is that the first connecting piece 10 is perpendicular to the direction of the paper surface.

[0047] It should be understood that the so-called perpendicular in the entire application does not require that the included angle between the two must be 90°, but allows a deviation of, for example, ±10°, that is, the so-called perpendicular can be understood as the included angle between any two directions being 80° to 100°. Similarly, the so-called parallel in the entire application does not require that the included angle between the two must be 0° or 180°, but allows a deviation of, for example, ±10°, that is, the so-called parallel can be understood as the included angle between any two directions being 0° to 10° or 170° to 190°.

[0048] As shown in Figure 3 , in the folded assembly state between the first connecting piece 10 and the second connecting piece 20, part of the first limiting surface 122 of the first connecting piece 10 abuts against the free end 228 of the bending portion 222 of the second connecting piece 20, and the bending portion 222 elastically deforms to abut against the first limiting surface 122. At the same time, since the rotating piece 22 completely covers the outer periphery of the rotating shaft 12, under the elastic restoring force of the rotating piece 22, the rotating shaft 12 can be tightly gripped and locked, that is, a locking force is formed on the rotating shaft 12, so that the rotating shaft 12 and the rotating piece 22 are kept stable in the current assembly state;

[0049] When it is necessary to change the assembly state of the first connecting member 10 and the second connecting member 2, a force needs to be applied to overcome the elastic restoring force generated by the elastic deformation of the rotating member 22. At the same time, during the process of applying a force to make the rotating member 22 rotate around the rotating shaft 12, the first limiting surface 122 will also be separated from the bent portion 222 in the abutting contact state, so as to overcome the locking force and realize the switching from the folded assembly state to the unfolded assembly state.

[0050] Furthermore, as Figure 3 shown, in an embodiment of the present application, when the bent portion 222 is placed on the first limiting surface 122, there is an included angle α between the first limiting surface 122 and the inner surface of the bent portion 222, and the included angle α is 5°-30°. In this way, by the end of the first limiting surface 122 far from the first arc surface 121 abutting against the inner surface of the bent portion 222, the bent portion 222 undergoes obvious elastic deformation, and further, the rotating shaft 12 and the rotating member 22 can maintain a relatively stable state at this rotation position.

[0051] As Figure 2 shown, in some embodiments, when the first connecting member 10 and the second connecting member 20 are in the unfolded assembly state, that is, when the temple and the frame are in the wearing state, at this time, the bent portion 222 rotates to a position where it abuts against the second limiting surface 222, the bent portion 222 extends along the length direction perpendicular to the second mounting plate 21, and the first limiting surface 122 extends obliquely inward along the length direction perpendicular to the first mounting plate 11. It should be noted that the inner side here is the side towards which the first limiting surface 122 faces. Specifically, when assembled on the glasses, the inner side here is the side of the wearing area of the glasses. In this way, when the second connecting member 20 rotates relative to the first connecting member 10 to be parallel or in the same extending direction, a part of the bent portion 222 abuts against the second limiting surface 123. Therefore, there is not a complete fit between the second limiting surface 123 and the inner surface of the bent portion 222, but there is an angular difference. The end of the second limiting surface 123 adjacent to the first arc surface 121 abuts against the free end 228 of the bent portion 222, and the end of the second limiting surface 123 adjacent to the second arc surface 124 is separated from or in non-pressure contact with the non-free end 227 of the bent portion 222. At this time, the bent portion 222 undergoes elastic deformation under the abutting action of the first arc surface 121, and further, the rotating shaft 12 and the rotating member 22 can maintain a relatively stable state at this rotation position.

[0052] Furthermore, as Figure 4As shown, in one embodiment of the present application, when the bending portion 222 is placed on the second limiting surface 123, the second limiting surface 123 and the inner surface of the bending portion 222 have an included angle β, which can be 5°-30°. In this way, the second limiting surface 123 can abut against the inner surface of the bending portion 222 at the end adjacent to the first arc surface 121, so that the bending portion 222 is elastically deformed, and the rotating shaft 12 and the rotating member 22 can be kept in a relatively stable state at the current assembly state.

[0053] As shown in FIG. 1, the first connecting member 10 and the second connecting member 20 are in an unfolded assembly state. Figure 4 As shown, when the first connecting member 10 and the second connecting member 20 are in an unfolded assembly state, the second limiting surface 123 of the first connecting member 10 abuts against the free end 228 of the bending portion 222 of the second connecting member 20, and the bending portion 222 is elastically deformed to abut against the second limiting surface 123. At the same time, since the rotating member 22 completely covers the outer periphery of the rotating shaft 12, the rotating member 22 can tightly hold and lock the rotating shaft 12 under the elastic restoring force, i.e., a locking force is formed, so that the rotating shaft 12 and the rotating member 22 are kept stable at the current assembly state.

[0054] When it is necessary to change the assembly state of the first connecting member 10 and the second connecting member 20, an acting force needs to be applied to overcome the elastic restoring force generated by the elastic deformation of the rotating member 22. At the same time, in the process of rotating the rotating member 22 around the rotating shaft 12 by applying the acting force, the second limiting surface 123 will be separated from the abutting contact with the bending portion 222, so as to overcome the locking force and realize the switching from the unfolded assembly state to the folded assembly state.

[0055] As shown in FIG. 1, the first connecting member 10 and the second connecting member 20 are in an unfolded assembly state. Figure 1 and Figure 2 As shown, in some embodiments, the outer diameter of the first arc surface 121 is not greater than the inner diameter of the arc portion 221. In this way, the rotating member 22 can be stably rotated around the rotating shaft 12 without being easily deviated or shaken, so as to ensure that the second connecting member 20 is stably rotated relative to the first connecting member 10.

[0056] For example, the outer diameter of the first arc surface 121 is greater than the inner diameter of the arc portion 221. In this way, when the arc portion 221 is tightly connected with the first arc surface 121, the arc portion 221 can tightly hold the rotating shaft 12 to provide a damping force during the rotation of the rotating member 22 relative to the rotating shaft 12, so as to avoid the second connecting member 20 from being randomly rotated relative to the first connecting member 10.

[0057] As shown in FIG. 1, the first connecting member 10 and the second connecting member 20 are in an unfolded assembly state. Figure 1 and Figure 2As shown, in some embodiments, the pivot 12 further has a second arcuate surface 124. The second arcuate surface 124 is disposed between the first limiting surface 122 and the second limiting surface 123. During the rotation of the rotating member 22 around the pivot 12, the bent portion 222 rotates between the first limiting surface 122, the second arcuate surface 124, and the second limiting surface 123. During the rotation of the bent portion 222 from the first limiting surface 122 to the second limiting surface 123, or from the second limiting surface 123 to the first limiting surface 122, the second arcuate surface 124 plays a guiding and stress-reducing role, making the rotation process smoother and the stress distribution more uniform, thereby improving the service life of the hinge.

[0058] In another embodiment of this application, the outer diameter of the second arcuate surface 124 is the same as the outer diameter of the first arcuate surface 121. In this way, when the rotating member 22 is sleeved on the rotating shaft 12, it can be ensured that the rotating member 22 and the rotating shaft 12 can be tightly connected, and it is not easy to shift or wobble. This ensures that the second connecting member 20 rotates stably relative to the first connecting member 10.

[0059] like Figure 3 and Figure 4 As shown, in some embodiments, the distance from the inner surface of the bent portion 222 to the center of the rotating shaft 12 is the same as the distance from the first limiting surface 122 to the center of the rotating shaft 12, and / or, the distance from the inner surface of the bent portion 222 to the center of the rotating shaft 12 is equal to the distance from the second limiting surface 123 to the center of the rotating shaft 12. In this way, during the rotation of the rotating member 22 relative to the rotating shaft 12, it can stably rotate around the center of the rotating shaft 12 and is less prone to deviation.

[0060] In another embodiment of this application, such as Figure 5 As shown, the first mounting plate 11 and the rotating shaft 12 of the first connector 10 are integrally formed. The first mounting plate 11 is provided with a first limiting member 111, and the second mounting plate 21 is provided with a first limiting piece 211. The first limiting member 111 is used to abut against the first limiting piece 211 when the first connector 10 and the second connector 20 are in the fully unfolded assembly state, so as to limit the rotation angle of the second connector 20, thereby limiting the outward expansion angle of the first connector 10 and the second connector 20 and improving the reliability of the hinge structure.

[0061] Optionally, the position of the first limiting member 111 on the first mounting plate 11 is adjustable, so that the angle between the second mounting plate 21 and the plane perpendicular to the first mounting plate 11 is 80°-130°, thereby adapting to the wearing needs of users with different sizes and face shapes.

[0062] Exemplarily, the first mounting plate 11 is protruded at one end of the rotating shaft 12 to form a first limiting piece 111, the first limiting piece 111 is arranged on the side of the first mounting plate away from the second mounting plate 21, and the second mounting plate 21 is formed with a first limiting sheet 211 near the rotating member 22, and the first limiting piece 111 is located on the rotating path of the first limiting sheet 211.

[0063] As shown in Figure 6 some embodiments, the first mounting plate 11 is provided with a second limiting piece 112, the second mounting plate 21 is provided with a second limiting sheet 212, the second limiting piece 112 is used to abut against the second limiting sheet 212 to limit the rotating position of the second connecting member 20 when the first connecting member 10 and the second connecting member 20 are in the fully folded assembly state, thereby limiting the folding angle of the first connecting member 10 and the second connecting member 20 and improving the reliability of the hinge structure.

[0064] Exemplarily, the first mounting plate 11 is protruded at one end of the rotating shaft 12 to form a second limiting piece 112, the second limiting piece 112 is arranged on the side of the first mounting plate close to the second mounting plate 21, and the second mounting plate 21 is formed with a second limiting sheet 212 near the rotating member 22, and the second limiting piece 112 is located on the rotating path of the second limiting sheet 212.

[0065] Further, the first limiting sheet 211 and the second limiting sheet 212 are the same structural member.

[0066] In the present application, when the hinge structure 100 is applied to glasses, the position of the second limiting piece 112 can be adjusted according to the wearing requirements of the user to adjust the unfolding angle of the temple relative to the frame, for example, the unfolding angle of the temple relative to the frame in the unfolded state of use can be 80°-130°.

[0067] As shown in Figure 5 and Figure 6 some embodiments, the end of the rotating shaft 12 away from the first mounting plate 11 is provided with a limiting piece 13, and the rotating member 22 is sleeved on the rotating shaft 12 and arranged between the limiting piece 13 and the first mounting plate 11. Through the limiting piece 13, the rotating member 22 can stably rotate relative to the rotating shaft 12 and is not easy to move along the axial direction of the rotating shaft 12, thereby enabling the first connecting member 10 to stably rotate relative to the second connecting member 20. When the hinge structure 100 is applied to glasses, the temple can stably rotate relative to the frame.

[0068] Exemplarily, when connecting the first connecting member 10 and the second connecting member 20, the rotating member 22 can be sleeved on the rotating shaft 12 first, and then the limiting piece 13 and the end of the rotating shaft 12 are fixedly connected, so that the rotating member 22 can stably rotate relative to the rotating shaft 12.

[0069] As shown in Figure 7 the smart glasses 1000 of the embodiment of the present application, the frame 200, the temple 300 and the hinge structure 100 are included. The frame 200 and the temple 300 are connected through the hinge structure 100. Specifically, the first connecting piece 10 connects the frame 200, the second connecting piece 20 connects the temple 300, and the folding and unfolding of the temple 300 relative to the frame 300 are realized through the rotation of the second connecting piece 20 relative to the first connecting piece 10.

[0070] The smart glasses 1000 of the embodiment of the present application can make the second connecting piece 20 in a stable state at different rotating positions when rotating relative to the first connecting piece 10 through the hinge structure 100, and further can ensure the position stability of the smart glasses 1000 in the folded state and the unfolded state for use, so as to improve the user experience.

[0071] As shown in Figure 7 in some embodiments, the smart glasses 1000 further include a first fastener (not shown in the figure), which fastens the first mounting plate 11 and the frame 200.

[0073] As shown in Figure 5 in some embodiments, the smart glasses 1000 further include a second fastener (not shown in the figure), which fastens the second mounting plate 21 and the temple 300. The second connecting piece 20 can be fixed in the temple 300 through the second fastener, so as to ensure the stable rotation of the second connecting piece 20 relative to the first connecting piece 10, and further ensure the stable rotation of the temple 300 relative to the frame 200.
