1, the relevant description
car central locking means provided on the driver’s seat door switch, it can be controlled simultaneously with the whole car door is closed one kind of opening control means. This “central locking” control device, as early as in the 1970s has been assembled in the car, after more than twenty years, has been used relatively common.
Central locking using a switch to control other switch actuators are two forms: one form is an electromagnetic coil, the other is in the form of a DC motor. Two forms are converted to the direction of movement of the object by changing the polarity of the DC, performing close or open operation.
It is a multi-car central locking solenoid type. Its work process is as follows:
lock: the forward current to the electromagnetic coil, the armature moves to the left connecting rod drive, lock buckle tongue.
open: when the reverse current to the electromagnetic coil, the armature moves to the right drive link, from the door lock tongue.
type DC motor works, the link driving force is provided by a reversible DC motor, the use of forward and reverse motor to lock the door and the door opening operation is completed. Universal application
car central locking, making the vehicle to the intelligent, humane direction a step forward. So that a driver without leaving your seat, you can easily control the opening and lock the whole car door. But car central locking applications also bring some problems. First, after the driver turns on the driver side lock, the rest of the car door automatically opened.
