AI Technical Summary

Technical Problem

Existing vehicle seat rotation mechanisms suffer from reduced operational sensitivity and decreased stability due to factors such as accumulated tolerances, dimensional accuracy, and gear backlash. In particular, the movement between gears affects the stability of the vehicle seat.

Method used

A separate drive module is installed between the fixed part and the rotating part of the rotating device. Through the combination of brake drum, brake components and rollers, and with the design of pressure protrusions and elastic components, power is stably transmitted, eliminating the wandering caused by external forces and improving operational sensitivity and stability.

Benefits of technology

It achieves stable and sensitive rotation of the vehicle seat rotation device, improving passenger comfort, and improves production efficiency and product manageability by simplifying the shape of the brake drum.
