Description

Technical Field

[0001] The utility model relates to the technical field of lock body equipment, in particular to an anti-shaking lock body for a central control door lock of an automobile. Background Art

[0002] The car central door lock is a door lock that centrally controls the locking and opening of the four car doors. Its working principle is to convert electrical energy into mechanical energy, and drive the gears to rotate in the positive and negative power conversion of the motor to complete the opening and closing process. The traditional car central door lock can basically meet people's use needs, but there are still certain problems. The specific problems are as follows: 1. Most of the car central door locks on the market cannot open the door when the remote control key is accidentally forgotten in the car, and the only choice is to force the lock or use the spare key; 2. Most of the car central door locks on the market have large mechanical noise when in use, and there is no noise reduction mechanism, which makes it inconvenient for users to use.

[0003] The application number is CN202020771489.3, which discloses an anti-mislocking automobile central control door lock, including a central control door lock body, a lock tongue hole is opened at the lower end of the left side wall of the central control door lock body, a sliding mechanism is fixedly installed on the left side of the bottom of the inner cavity of the central control door lock body, a lock tongue body is fixedly installed on the top of the sliding mechanism, an infrared laser rangefinder is fixedly installed on the upper end of the left side wall of the central control door lock body, a single chip is fixedly installed on the left side of the top of the inner cavity of the central control door lock body, the infrared laser rangefinder and the single chip are electrically connected, and an unlocking relay body is fixedly installed on the left side of the top of the inner cavity of the central control door lock body, and the single chip is electrically connected to the unlocking relay body. When the user gets off the car, the infrared laser rangefinder detects that the distance increases sharply vertically and then returns to the original value, transmits the signal to the single chip to identify the code and control the micro motor to drive the lock tongue body to move to the right, thereby preventing mislocking.

[0004] The above document discloses an anti-mislocking automobile central control door lock having the following defects: during use of the door lock, the lock core needs to be repeatedly extended and retracted to lock the door. At this time, a corresponding limiting structure needs to be set to ensure that the lock core moves smoothly in the lock body. The structure does not have a corresponding structure, and the lock core is prone to deviation when moving in the lock body, resulting in the device being not flexible enough.

[0005] It can be seen from this that the existing automobile central door lock does not have the function of making the lock core move in a stable translation. It is necessary to improve the existing deficiencies and provide a function that can make the lock core move in a stable translation. Utility Model Content
