Automobile emergency unlocking system

Abstract

The invention provides an automobile emergency unlocking system. The automobile emergency unlocking system comprises a lock assembly, the lock assembly is connected with an outward opening pull rod and an inward opening pull wire, the inward opening pull wire is connected with an inward opening handle, and the automobile emergency unlocking system is characterized in that an unlocking actuator isstarted to release pressure gas so as to drive and release automobile door lock safety when a collision detection module detects that an automobile severe collision accident occurs. According to the automobile emergency unlocking system, when the collision detection module detects the automobile severe collision accident, the unlocking actuator is started to release the pressure gas so as to driveand release the automobile door lock safety, so that the automobile door lock safety is opened; and according to the automobile emergency unlocking system, door lock safety opening and air bag detonation are completed at the same time, namely, the automobile door lock safety is directly relieved through the collision severe degree obtained through air bag detonation, a new collision severe degreesignal collecting sensor does not need to be additionally arranged, it can be guaranteed that the automobile door lock safety is opened in time, the response hysteresis caused by an intermediate linkthat an automobile body controller is unlocked after processing a signal in the prior art is reduced, the time is saved, and the risk is reduced.

Description

technical field [0001] The invention belongs to the field of vehicle door locks, and in particular relates to an emergency unlocking device for vehicle door locks. Background technique [0002] At present, the door locks of automobiles generally have the function of securing (travel lock) or manually securing by the driver during vehicle driving. In the securing state, the door cannot be opened by opening the handle from outside the vehicle.

[0003] At present, there are several ways to open the door lock safely after the collision: [0004] 1. If the driver and passengers in the accident car can still open the door, the driver and passengers can open the ins...

AI Technical Summary

Problems solved by technology

[0007] The disadvantages of the above technologies are specifically manifested in that the collision signal output by the detection module needs to be processed by the body controller, and then the collision unlocking signal is sent to make the door lock unlocking structure act to realize the opening of the door lock. The whole process takes a long time. If the power supply of the vehicle is cut off, there will be a problem that the door lock insurance cannot be opened.
