Automobile side door lock

Abstract

The invention discloses an automobile side door lock. The automobile side door lock comprises a lock body assembly and an execution assembly, a motor of the execution assembly rotates in the preset direction and drives a worm to further drive a worm wheel to rotate anticlockwise, the worm wheel drives a safety rod to slide rightwards, and a clutch rod rotates clockwise under the torsion effect ofa clutch rod torsion spring; the clutch rod and a first conversion plate form an unlocking safety, at the moment, a first inner pull plate of a lock catch assembly is pulled to overcome the torsion ofa torsion spring of the first inner pull plate to rotate clockwise, the first conversion plate is shifted to drive the clutch rod and a release plate to rotate, and the release plate drives a pawl pin and a pawl to rotate; when the pawl rotates to the state that the pawl does not limit a clamping plate and is disengaged from the clamping plate, the clamping plate rotates under the acting force ofa clamping plate torsional spring to enable the side door lock to be unlocked, and namely, the vehicle door is opened. According to the automobile side door lock, the number of components forming thelock body assembly and the execution assembly is relatively small, the number of the components formed by parts is relatively small, and the flexibility and mechanical property of connection betweenthe components are ideal.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an automobile side door lock. Background technique [0002] The automobile side door lock of the prior art is a very mature technology, and generally includes a lock body assembly and an executive assembly, and the executive assembly also has an actuator assembly or a lock block. The clamping plate or lock tongue that the rivet rotates constitutes the basic locking unit, and then the motor in the executive assembly is used to drive the worm gear electric mechanism and other manual mechanisms to secure or release the security, and then unlock from outside or inside the vehicle. The structures of the automobile side door locks of the prior art are different, and the functions are different. But according to applicant's understanding, the automobile side door lock of prior art still has the following deficiencies: 1. The parts that constitute side door lock are relatively many, ...

AI Technical Summary

Problems solved by technology

But according to applicant's understanding, the automobile side door lock of prior art still has the following deficiencies: 1. The parts that constitute side door lock are relatively many, and the parts that parts constitute are relatively many, and the occupied space is relatively large, and the flexibility and mechanical performance of connection between parts Not ideal, the flexibility is not enough during the unlocking and locking operation, the reliability is not strong, the operation is relatively laborious, and the service life of the lock is affected to a certain extent

2. Due to the relatively large number of components, the relatively high cost of materials, the relatively large number of assembly processes, the relatively low assembly efficiency, and the relatively increased assembly labor costs, the price competitive advantage of the product is not obvious

3. Some executive components adopt a split structure of the front cover and electrical components, the waterproof effect is not ideal, which increases the difficulty of assembly

4. Some parts have abnormal noise, which increases the noise; some parts have low reliability and are inconvenient to assemble
