[0028] This utility model embodiment provides a glasses hinge structure B for rotatable connection between the frame 60 and temple 70 of glasses. This glasses hinge structure B can be applied to conventional optical vision correction glasses, as well as to protective eyewear, smart glasses, and other scenarios. In this embodiment, referring to... Figures 1-5 The eyeglass hinge structure B includes a sleeve 10, a core 20, an elastic element 30, and a positioning element 40. The sleeve 10 has a receiving hole 11 extending along a first axis AX1, the core 20 is disposed in the receiving hole 11, and the sleeve 10 and the core 20 are capable of relative rotation about the first axis AX1. (Refer to...) Figure 6 When the eyeglass pivot structure B is installed on the eyeglasses, one of the sleeve 10 and the core 20 is connected to the frame 60, and the other is connected to the temple 70, thereby allowing the temple 70 to rotate around the first axis AX1 with respect to the frame 60. Optionally, the sleeve 10 may also have an extension rod 13 on its outer side, which can be embedded in the frame 60 or the temple 70 to achieve a secure connection with the frame 60 or the temple 70.

[0029] The sleeve 10 has one or more positioning holes 12 on its side wall, and the extension direction of the positioning holes 12 is substantially perpendicular to the first axis AX1. The core 20 has a mounting channel 21, which is perpendicular to the first axis AX1. An elastic element 30 is disposed in the mounting channel 21, and the extension and retraction direction of the elastic element 30 is parallel to the extension direction of the mounting channel 21. The elastic element 30 has at least one mounting end 31, and a positioning element 40 is disposed at the mounting end 31. Under the action of the elastic force of the elastic element 30, the positioning element 40 tends to extend away from the mounting channel 21. When the sleeve 10 rotates relative to the core 20, the positioning element 40 moves along the inner wall surface of the receiving hole 11. The friction between the positioning element 40 and the inner wall of the receiving hole 11 can provide a certain damping force. When the positioning element 40 is aligned with the positioning hole 12, the elastic force of the elastic element 30 presses at least a portion of the positioning element 40 into the positioning hole 12. This process can provide tactile feedback to the user, letting the user know that the temple 70 has rotated to the predetermined position.

[0030] The elastic element 30 may include a gas spring, a hydraulic spring, a compression spring, a block elastomer, or other elastic structures. In one embodiment, the elastic element 30 may be a compression spring, such as a cylindrical helical spring, with the outer diameter of the compression spring being larger than the diameter of the positioning hole 12, so that the inner wall of the receiving hole 11 can block the compression spring to prevent the compression spring from extending into the positioning hole 12.

[0031] In one embodiment, the compression spring has a hollow portion 32, and the end of the positioning member 40 away from the positioning protrusion 41 has a limiting portion 42, which extends into the hollow portion 32 to achieve positioning of the positioning member 40 and the compression spring.

[0032] In one embodiment, the eyeglass pivot structure B includes a positioning element 40, which is disposed at one mounting end 31 of the elastic element 30. The other end of the elastic element 30 opposite to the positioning element 40 can be fixedly connected relative to the core 20. The sleeve 10 may have one or more positioning holes 12. When the sleeve 10 has multiple positioning holes 12, the multiple positioning holes 12 can be arranged circumferentially at intervals along the receiving hole 11. The arrangement of the multiple positioning holes 12 substantially coincides with the movement trajectory of the positioning element 40 in the receiving hole 11 when the sleeve 10 rotates relative to the core 20, thereby providing the user with tactile feedback and hovering at multiple predetermined positions.

[0033] In some embodiments, refer to Figure 3 The elastic element 30 has two mounting ends 31 arranged opposite each other in the extension / contraction direction. The positioning element 40 includes two parts, with one positioning element 40 on each mounting end 31. For example, when the elastic element 30 is a compression spring, both ends of the compression spring are mounting ends 31, and each mounting end 31 is provided with a positioning element 40. The sleeve 10 has at least one group of positioning holes 14, each group of positioning holes 14 having two oppositely arranged positioning holes 12. When the sleeve 10 rotates relative to the core 20 to at least one position, each positioning element 40 extends into the corresponding positioning hole 12 of the group of positioning holes 14. For example, refer to… Figure 3 and Figure 4 The sleeve 10 includes two opposing positioning holes 12, which together form a positioning hole group 14. When one positioning member 40 extends into one positioning hole 12 of the positioning hole group 14, the other positioning member 40 also extends into the other positioning hole 12 of the positioning hole group 14. This allows for a more obvious feel of being in place and a more stable positioning and hovering.

[0034] In some embodiments, refer to Figure 5 The sleeve 10 has more than two positioning holes 12 and forms multiple positioning hole groups 14, with the positioning holes 12 of the multiple positioning hole groups 14 spaced apart circumferentially along the receiving hole 11. When the eyeglass pivot structure B is installed on the eyeglasses, the positioning member 40 moves to different positioning hole groups 14, corresponding to different positions of the temple 70 relative to the frame 60, thereby enabling feedback and hovering of multiple different positions when the temple 70 is unfolded / folded.

[0035] Reference Figures 1-3The core 20 includes a rotating section 22, which is disposed in the receiving hole 11 and can rotate relative to the sleeve 10 within the receiving hole 11. An installation channel 21 is disposed within the rotating section 22. The diameter of the rotating section 22 is slightly smaller than the diameter of the receiving hole 11, so that the sleeve 10 can rotate smoothly relative to the core 20, while preventing excessive gap between the sleeve 10 and the core 20 from causing wobbling and loosening of the connection between the temple 70 and the frame 60. Optionally, the diameter of the receiving hole 11 is 0.05mm-0.1mm larger than the diameter of the rotating section 22, ensuring a good fit between the sleeve 10 and the rotating section 22.

[0036] The rotating segment 22 has a first end and a second end disposed opposite to each other along the first axis AX1. In one embodiment, the core 20 includes a stop 23, which is disposed at the first end of the rotating segment 22 and has a lateral dimension larger than the receiving hole 11. The stop 23 is disposed opposite to the end face of the sleeve 10 to limit the movement of the core 20 and the sleeve 10 along the first axis AX1. After the sleeve 10 is fitted over the rotating segment 22, the sleeve 10 can be stopped from the other end of the rotating segment 22 by a stop block or other structure to achieve axial fixation between the sleeve 10 and the core 20. In some embodiments, the core 20 also has a protrusion 24 at the second end of the rotating segment 22. When the stop 23 abuts against the end face of the sleeve 10, the protrusion 24 protrudes from the receiving hole 11 and extends out of the sleeve 10. The protrusion 24 has a first connecting hole 241. The eyeglass hinge structure B also includes a connector 50, which is used to connect to the first connection hole 241 to connect the core 20 to the eyeglass frame 60 or temple 70. For example, the sleeve 10 is fixedly connected to the temple 70, see reference. Figure 3 After the sleeve 10 is placed over the rotating section 22, the protrusion 24 can be aligned with the corresponding connecting structure on the frame 60, so that the first connecting hole 241 is aligned with the second connecting hole 61 on the connecting structure. The first connecting hole 241 and the second connecting hole 61 are connected by the connector 50 to complete the assembly of the frame 60, temple 70 and eyeglass pivot structure B. The operation is simple and convenient.

[0037] In one embodiment, the positioning element 40 can be a ball bearing, which can be fixed to the mounting end 31 by welding or other means. When the sleeve 10 rotates relative to the core 20, the ball bearing slides along the inner wall of the receiving hole 11. When the positioning hole 12 aligns with the ball bearing, the ball bearing is at least partially pressed into the positioning hole 12 by the elastic force of the elastic element 30, providing tactile feedback to the user. The mutual compression between the ball bearing and the inner wall of the positioning hole 12 increases the resistance to the continued rotation of the sleeve 10 relative to the core 20, thereby enabling the positioning of the opening angle between the temple 70 and the frame 60 and, to a certain extent, the suspension.

[0038] In one embodiment, refer to Figure 1 and Figure 3The positioning member 40 has a positioning protrusion 41. When the positioning member 40 is aligned with the positioning hole 12, the elastic force of the elastic member 30 presses at least a portion of the positioning protrusion 41 into the positioning hole 12. Preferably, the positioning protrusion 41 has an arcuate surface. When the positioning protrusion 41 moves along the inner wall of the receiving hole 11, the arcuate surface abuts against the inner wall of the receiving hole 11 to reduce friction and prevent noise.

[0039] Another aspect of this utility model relates to a smart pair of glasses, including a frame 60, temples 70, and the eyeglass hinge structure B described in at least some of the embodiments above. One of the frame 60 and temples 70 is connected to the sleeve 10 of the eyeglass hinge structure B, and the other is connected to the core 20.

[0040] In one embodiment, the frame 60 is fixedly connected to the core 20, and the sleeve 10 is connected to the temple 70 and disposed at the end of the temple 70. The temple 70 and frame 60 can be rotatably connected via the eyeglass pivot structure B. When the temple 70 rotates relative to the frame 60, the sleeve 10 rotates around the core 20. When the positioning member 40 aligns with the positioning hole 12, the elastic force of the elastic member 30 provides corresponding tactile feedback. The connection between the positioning member 40 and the positioning hole 12 allows the temple 70 to be suspended at that position. Optionally, a conductive terminal can also be provided in the positioning hole 12. The conductive terminal is electrically connected to a first circuit in the frame 60, and the positioning member 40 can be a metal conductor and electrically connected to a second circuit in the temple 70. When the positioning member 40 rotates to the position of the positioning hole 12 and is pressed into the positioning hole by the elastic member 30, the positioning member 40 contacts the conductive terminal to conduct the first and second circuits.

[0041] This utility model provides a glasses hinge structure B and smart glasses. The glasses hinge structure B includes a sleeve 10, a core 20, an elastic element 30, and a positioning element 40. The sleeve 10 has a receiving hole 11 extending along a first axis AX1, and a positioning hole 12 on its side wall. The core 20 is disposed in the receiving hole 11 and has an installation channel 21. The elastic element 30 is disposed in the installation channel 21 and has at least one mounting end 31. The sleeve 10 and the core 20 are connected in a manner that allows them to rotate relative to each other around the first axis AX1. The positioning element 40 is disposed at the mounting end 31. When the positioning element 40 is aligned with the positioning hole 12, the elastic force of the elastic element 30 presses at least a portion of the positioning element 40 into the positioning hole 12, thereby providing the user with tactile feedback that the temple 70 has rotated to a predetermined position. In addition, the glasses hinge structure B of this utility model is simple, reliable, and easy to install, which is beneficial to the lightweight design of smart glasses.
