Since the 21st century, in order to improve the overall comfort, safety, and ease of use of vehicles, automotive engineers have paid much attention to the experience that the electrical components of vehicles bring to the user. The car central locking system is now standard in mid-range and high-end cars and is usually installed in the center console or at the door locking body. The central locking enables the driver can control every door from a device, which is widely used because of its convenience.

The functions of central locking

The car central lock system is a system device that provides positioning for door closing and can accept control for opening operation. It plays the role of opening and closing the doors, ensuring the safety of the occupants, and preventing the illegal opening of the doors.

1. Central control

When the driver locks the door beside him, the other doors are also locked at the same time. If you want to open the doors, you can open each door at the same time through the central lock switch, or open a door individually.

2. Automatic locking

Generally, when the driving speed reaches a certain speed (15km/h), each door will be automatically locked to prevent the occupants from improperly operating the door handle to open the door by mistake. When the vehicle is turned off and the key is removed, the central locking will automatically unlock the doors.

Car central locking structure and working principle

The central locking in a car basically consists of a door lock signal switch, an internal actuator, and a door lock control mechanism. When the central control switch is touched, the switch relay turns on and the normally closed contact of the micro switch is connected. The door lock control mechanism moves and drives the actuator in the door lock to realize the action of locking and unlocking the central control.
