AI Technical Summary

Technical Problem

In vehicle emergencies, when the electronic door lock system fails, passengers may find it difficult to open the doors quickly. Existing technologies often use mechanical backup handles that are hidden and complex to operate, which delays escape opportunities. Furthermore, opening the door and unfastening the seatbelt require separate steps, increasing the difficulty.

Method used

Design an automotive mechanical emergency door opening device, comprising a mounting frame, a latch seat, a rotating mechanism, a sensor assembly, and an automatic drive assembly. The sensor monitors the vehicle status in real time and automatically or manually drives the rotating mechanism to unlock the door and seat belt, forming a dual-redundancy architecture to ensure operation even in the event of electronic system failure.

Benefits of technology

In the event of electronic system failure or occupant unconsciousness, the doors and seat belts are automatically unlocked without occupant intervention, significantly improving the escape success rate in emergencies and providing multiple safety guarantees.

Abstract

The application discloses a mechanical emergency door opening device for a vehicle and a control method thereof, and relates to the technical field of emergency door opening devices for vehicles. The mechanical emergency door opening device comprises a mounting frame fixedly connected to the outer side of a vehicle frame and a safety belt buckle, and further comprises a lock buckle seat fixedly connected to the outer side of the mounting frame, a fixed cylinder fixedly connected to the inside of the mounting frame, a lock bolt arranged in the fixed cylinder, the lock bolt penetrating through the mounting frame and being in contact with the inside of the lock buckle seat, and an elastic mechanism arranged in the fixed cylinder. A manual driving mechanism and an automatic driving assembly constitute a double-redundancy architecture, and both of them can independently drive a rotating mechanism. Even in the case of power failure of the whole vehicle or complete failure of the electronic system, the manual driving mechanism can still complete the unlocking operation through a pure mechanical mode, thereby providing multiple safety guarantees for passengers.
