Abstract

A vehicle door lock is disposed in a vehicle door and includes a ratchet wheel rotatable between a locked position where it captures a lock catch disposed on a vehicle body and an unlocking position where it releases the lock catch to allow the vehicle door to be opened. The vehicle door lock further includes an ice-breaking mechanism disposed in the vehicle door, and the ice-breaking mechanism applies a torque to the ratchet wheel to cause the ratchet wheel to rotate in a direction to push the lock catch so as to open the vehicle door. The vehicle door lock can be opened by pushing the ratchet wheel with e ice-breaker mechanism when the vehicle door is frozen or deformed due to collision, the operation noise is low, the cost is low, and the paint surface of the vehicle door is protected.
