AI Technical Summary

Technical Problem

Existing car seat sliding rail mechanisms lack auxiliary braking mechanisms during emergency braking at high speeds, causing damage to the locking levers due to inertia and seat belt tension, increasing the risk to life and health and reducing efficiency.

Method used

An automotive seat slide rail mechanism was designed, which includes a braking mechanism. It utilizes a speed sensor, an electric push rod, and a brake plate to perform emergency braking when the catch rod breaks. The controller controls the cooperation between the electric push rod and the brake plate to achieve rapid fixation of the slide.

Benefits of technology

In the event of a broken lever, the system effectively prevents passengers from being thrown forward due to inertia, improves the efficiency of the seat slide mechanism, and ensures passenger safety.
