Technical Field
[0001] The utility model relates to the field of glasses hinges, in particular to the hinge of smart glasses. Background Art
[0002] Smart glasses are wearable devices that integrate multiple functions. They not only have the vision correction function of traditional glasses but also incorporate high-tech elements such as built-in operating systems, Internet connections, multimedia playback, voice control, etc. With the progress of technology, significant improvements have been made in the design innovation and user experience optimization of smart glasses. The design of smart glasses increasingly focuses on the fashion of appearance and the comfort of wearing, using lighter materials while maintaining the strength and durability of the device. Some smart glasses adopt foldable or modular designs, improving portability and the possibility of personalized customization.
[0003] In current technical practices, the rotation of the glasses frame usually relies on a spring mechanism to achieve control. However, this design often requires a large space for layout during implementation, which not only increases the complexity of the design but may also conflict with the installation of other components, resulting in a cumbersome installation process and easy interference between components, thus causing inconvenience in operation. Summary of the Utility Model

The structure is ingenious, convenient and practical.
[0013] (2) By arranging an opening on the connecting body, the first installation cavity and the second installation cavity are opened through the opening, which is convenient for the installation and disassembly of the torsion spring and the limiting plate, and thus convenient for the replacement of the torsion spring and the limiting plate.

Installation holes 10 are provided on each external connecting plate portion. The external connecting plates on the first bracket 11 and the external connecting plates on the second bracket 12 are fixedly connected by locking members.
[0035] Working principle of the present utility model: During the use of the present utility model, first install the leaf spring 7 on the damping plate 132, install the torsion spring 4 on the middle rotating shaft 3 through the opening, one end of the torsion spring 4 is installed in the first positioning groove 133, and the other end of the torsion spring 4 passes through the second positioning groove 63 and extends into the third limiting groove 142. Then, fix and connect the external connecting plates on the first bracket 11 and the second bracket 12 through the locking parts. Then, connect the first rotating frame 1 with the spectacle frame, and connect the second rotating frame 2 with the temple. After the connection is completed, when the temple and the spectacle frame are in the folded state, the limiting slider 61 is not in contact with the side wall of the first limiting groove 26, the first limiting block 27 is pressed against the side of the second limiting groove 141, and the second limiting block 62 is pressed against the side wall of the third limiting groove 142. When the temple rotates from the folded state to an angle of 90° with the spectacle frame, the leaf spring 7 on the damping plate 132 rubs against the inner wall of the inner cavity and provides damping for the opening of the temple. And when the temple and the spectacle frame rotate to 90°, the side wall of the first limiting groove 26 fits with the side wall of the limiting slider 61, the first limiting block 27 is not in contact with the side wall of the second limiting groove 141, and the side wall of the second limiting block 62 still presses against the side wall of the third limiting groove 142. The torsion spring 4 is in a pre-compressed state after assembly and does not generate torsion when the angle between the temple and the spectacle frame does not exceed 90°. However, when the temple expands outward to an angle exceeding 90° with the spectacle frame, the side wall of the first limiting groove 26 applies pressure to the side wall of the limiting slider 61, and the first limiting block 27 fits with the side wall of the second limiting groove 141, thereby limiting the outward expansion angle of the temple to 100°. And at this time, the second limiting block 62 is separated from the side wall of the third limiting groove 142. At this time, the torsion spring 4 generates torsion and generates a reverse elastic force, so as to ensure that the temple can return to the 90° position after outward expansion. The present utility model integrates the cooperation of the torsion spring 4, the leaf spring 7, the damping plate 132, the limiting slider 61 and the first limiting groove 26, the cooperation of the first limiting block 27 and the second limiting groove 141, and the cooperation of the second limiting block 62 and the third limiting groove 142 between the connecting body 22, the first positioning plate 13 and the second positioning plate 14, effectively solving the problems of large space layout and interference between components in the prior art. At the same time, while ensuring the saving of internal space, it also ensures the reset when the temple and the spectacle frame rotate excessively, ensuring the overall service life of the smart glasses, with a clever structure, convenient and efficient.
