Self-absorption back door lock

Abstract

A self-absorption back door lock includes a bottom plate and a lock body. A self-absorption pulling plate shaft, a ratchet shaft and a pawl shaft are arranged between the bottom plate and the lock body. The self-absorption pulling plate shaft is provided with a self-absorption pulling plate spring and a self-absorption pulling plate. The ratchet shaft is provided with a ratchet, a self-absorptionrocker arm, a ratchet spring, and a safe opening toggling arm. The self-absorption rocker arm is connected with a push plate spring and a push plate. The self-absorption rocker arm is also connected with a self-absorption linkage arm by a self-absorption linkage plate shaft. The self-absorption pulling plate is connected between the self-absorption linkage arm and the self-absorption pulling plateshaft. The pawl shaft is provided with a pawl, a pawl spring and a motor cover plate. One side of the lock body is connected with a pawl release arm spring, a pawl release arm, a motor driving component, an emergency opening spring, a second emergency opening rocker arm, a safe opening spring and a safe opening rocker arm. A safe opening linkage arm is connected between the safe opening rocker arm and the safe opening toggling arm through a second pin. The emergency opening rocker arm is also connected with an emergency opening inhaul cable. The self-absorption back door lock has high structural strength, is safe, reliable and multifunctional.

Description

Technical field [0001] The invention relates to the technical field of vehicle door locks, in particular to a HYX05 self-priming back door lock with high structural strength, safety and reliability, and multiple functions. Background technique [0002] With the continuous development of society, users have more and more detailed requirements for car functions. In order to meet market demand, more models need to be expanded. As an important part of the car body, car doors must meet the needs of people and goods entering and exiting. The airtightness isolates the inside of the vehicle body from the outside world. In addition, the door is required to be safe and reliable. The door will not automatically open when driving or in a collision. It can be opened normally after a collision. It has good anti-theft performance. In order to meet these requirements, the door and the body In addition to reasonable structure and proper strength, a safe and reliable lock system is also required; ...

AI Technical Summary

Problems solved by technology

[0002] With the continuous development of society, users' requirements for automobile functions are becoming more and more refined. In order to meet the market demand, more models need to be expanded; as an important part of the automobile body, the door has the function of satisfying the entry and exit of people and goods. Sealing, to isolate the inside of the car body from the outside world. In addition, the door is required to be safe and reliable. The door will not open automatically when driving or in a collision. It can be opened normally after a collision, and has good anti-theft performance. In addition to reasonable structure and proper strength, a safe and reliable lock system is also required; the front door lock of a car is an important part of the car, and its structural performance affects the safety and reliability of the entire car and the comfort of operation; The traditional split self-priming lock has two obvious defects:

[0003] 1. Once the unlocking motor in the lock fails, the door cannot be closed;

[0004] 2. Once the motor in the actuator fails, the door cannot be opened
