AI Technical Summary

Technical Problem

In existing automotive door drive mechanisms, the motor output shaft suffers severe wear due to one-sided contact, resulting in decreased stability and potential damage to the motor and transmission components when the door is opened or closed forcefully.

Method used

A coupling is used to connect the motor output shaft and the main shaft. A buffer is used to cushion the force, reduce wear on the motor output shaft, and protect the motor and transmission components when the door is opened or closed violently. Anti-explosion blocks and anti-explosion ports are used to prevent excessive compression.

Benefits of technology

It improves the stability of the motor output shaft, protects the motor and transmission components, reduces noise and wear, and enhances the stability and durability of the door drive mechanism.
