AI Technical Summary

Technical Problem

Existing vehicle door locks cannot stop closing in time under high sealing force, causing people or objects to be accidentally clamped by the door, posing a safety hazard.

Method used

A vehicle door lock engagement and interruption mechanism is designed, which includes a fixing seat, an interruption component and a connection component. The engagement and interruption of the vehicle door are achieved through the coordinated rotation of the guide groove and the guide column. The rotation of the engagement component and the connection component drives the guide column to deviate from the engagement trajectory, thereby interrupting the engagement of the vehicle door.

Benefits of technology

The door closing process can be interrupted at any time to avoid accidental entrapment of people or objects, thus improving safety.
