AI Technical Summary

Technical Problem

Existing rail vehicle locking devices are complex in structure and pose safety risks due to their separate installation. Mechanical failures can easily lead to accidental opening of the doors, threatening passenger safety.

Method used

The lock assembly employs a double-locking mechanism, including a main locking device and a second lock. The lock hook rotates between a first position and a second position, and the cooperation between the telescopic part and the opening ensures that the lock hook is reliably fixed in each position. The structure is simple, stable and reliable.

Benefits of technology

It reduces the probability of accidental opening of the car door, improves safety, avoids safety hazards caused by malfunction of the individual locking device, and simplifies manufacturing and maintenance costs due to the structural design.
