AI Technical Summary

Technical Problem

Existing hinges are difficult to use in functional furniture to achieve synchronous rotation and stable hovering, and the rotation angle is difficult to control precisely.

Method used

It adopts a centrally symmetrical double-rotor structure. Through the frictional connection between the rotating shaft and the rotor and the cooperation between the movable pin and the groove, the rotor can be rotated synchronously in opposite directions or out of direction. The rotational resistance can be adjusted by the friction pads to achieve hovering at any angle.

Benefits of technology

It achieves synchronous rotation and stable hovering of the rotating assembly, has a stable structure, can precisely control the rotation angle, and improves the load-bearing capacity and service life of the hinge.
