Description

Technical Field

[0001] The utility model relates to the technical field of automobile central control door locks, in particular to a sealing structure for automobile central control door locks. Background Art

[0002] At present, the central controller of the car door lock mostly uses an independent door lock driver to realize the switch state of the car central control door lock, as well as the control of the unlocking and locking state of the car central control door lock. The door lock and the door lock central control driver are relatively independent. The central control structure of this type of car door lock is too complicated, which is not conducive to the overall layout and installation of the car door lock.

[0003] After searching, the application with patent number CN206554657U discloses an integrated central control electrical device for automobile door locks, including a central control bracket plate, a motor and a control circuit. The motor and the control circuit are both arranged on the central control bracket plate, and the central control bracket plate is arranged in the automobile door lock. A worm is provided on the output shaft of the motor, and the motor is connected to the automobile lock body through the worm. The motor is connected to an external power supply through the control circuit. The control circuit controls the rotation of the motor, and the motor drives the worm to rotate forward or reversely, so that the automobile lock body is locked or unlocked, thereby improving the stability of the central control electrical device.

[0004] However, due to the setting of the central control bracket plate and the car door lock, external dust can easily enter the interior of the car door lock through the central control bracket plate, thereby affecting its service life and having low sealing performance. At the same time, since the car lock machine is not equipped with an automatic locking structure, people may accidentally touch the central control switch, thereby causing the car door to open, resulting in low safety and low anti-theft performance.

[0005] Therefore, we propose a sealing structure for a central door lock of an automobile. Utility Model Content
