Lock system and motor vehicle

By designing the locking tongue component, pawl component, locking lever, and unlocking lever to work in tandem, the problems of accidental locking of the locking tongue and noise were solved, achieving stable operation and low-noise operation of the lock system.

AI Technical Summary

Technical Problem

In existing vehicle locking systems, when the bolt rotates from the fully locked position to the partially locked position, the pawl may rotate in the direction of locking the bolt, causing the bolt to be incorrectly restricted to the partially locked position and generating noise.

Method used

A locking system was designed, which includes components such as a bolt assembly, a pawl assembly, a locking lever, and an unlocking lever. Through the coordinated action of the locking lever and the unlocking lever, the position of the pawl is controlled to ensure that the bolt can be smoothly rotated to the fully locked, half-locked, or open position, thereby reducing noise generation.

Benefits of technology

It effectively avoids accidental locking when the bolt is in the half-lock position, reduces noise interference, and improves the operational stability and user experience of the lock system.

Abstract

The present disclosure provides a lock system and a motor vehicle. The lock system comprises a bolt component, a pawl component, and a first reset component; the bolt component is configured to rotate around a first axis, and at least comprises a fully locked position and an open position; the pawl component is configured to rotate around a second axis, and at least comprises a first position and a second position; when being in the first position, the pawl component is used for restraining the bolt component in the fully locked position; when the pawl component is in the second position, the bolt component is allowed to move from the fully locked position to the open position; and the first reset member is used for providing a reset force for the pawl component, so that the pawl component has a movement tendency to move from the first position to the second position under the reset force.
