AI Technical Summary

Technical Problem

Existing eyeglasses have a flexible hinge structure that is prone to detachment, causing the frame to separate from the temples. Furthermore, the movable spring is prone to rigid deformation when it remains in a semi-open state for a long time, resulting in changes in resistance during the opening and closing process of the temples, making it impossible to open or close smoothly.

Method used

The glasses feature a spring-loaded hinge structure, where the temple head has a single tooth, and the temple end has an arc-shaped spring and a double tooth. The double tooth is hinged to the single tooth, and the spring abuts against the outer circumference of the single tooth. When the temple rotates, the spring rotates around the hinge point to achieve quick opening or closing, and releases elastic deformation force during rotation to meet the wearing needs of different face shapes.

Benefits of technology

The smoothness of the temples opening and closing has been improved to accommodate different face shapes, extend the service life of the hinges, and ensure a stable connection and wear resistance between the frame and the temples.
