AI Technical Summary

Technical Problem

The electronic collision recognition system in existing new energy vehicles malfunctions due to circuit damage during severe collisions, causing the exterior door handles to fail to pop out, posing a safety hazard.

Method used

An emergency trigger device is adopted, which uses inertial force to control the handle body to pop out. The handle is automatically unlocked through the mechanical structure of the unlocking component and the drive mechanism, avoiding reliance on circuits.

Benefits of technology

Even in the event of circuit failure or power outage, the handlebars can still automatically pop out, improving the safety and reliability of vehicle use and avoiding the problem of handlebars malfunctioning due to circuit failure.

Abstract

This application discloses an emergency triggering device, a door handle assembly, and a vehicle. The emergency triggering device includes an unlocking component and a drive mechanism. The center of rotation of the unlocking component is different from its center of gravity. The drive mechanism is locked to the unlocking component and is adapted to connect to the structure to be driven. After the emergency triggering device is impacted, the unlocking component rotates to unlock the drive mechanism, thereby unlocking the structure to be driven. According to the emergency triggering device of this application, when the emergency triggering device is impacted, the unlocking component can rotate to unlock the drive mechanism, thereby controlling the unlocking of the structure to be driven. The unlocking of the structure to be driven does not depend on the circuit, improving safety and reliability.
