AI Technical Summary

Technical Problem

Existing electric vehicle frames are prone to violent shaking when subjected to external impacts, affecting stability.

Method used

It adopts a bumper structure, combined with a rod pin and a spring damping shock absorber. The body vibration is reduced by the contraction of the rod pin inside the connector and the contraction of the spring damping shock absorber, and warning is provided by LED lights.

Benefits of technology

It effectively reduces vehicle vibration, improves safety, and uses LED lights to alert the driver to potential collisions, thus enhancing vehicle stability.
