Abstract
A remote control type of automatic control device for automobile door wherein of the car doors and its locking device is provided with a micro-switch for sensing the state of the car door and the state of the locking device. The locking devices are controlled by locking coils. The locking devices of all the car doors can be locked when a car-speed detecting circuit, a switch circuit and a delay circuit all have a specific output. When the car is parked, an unlocking trigger circuit can unlock all the locking devices. There is a receiving circuit to receive a signal sent by a remote control device. As soon as a signal is received, a trigger will be triggered. The output terminal of the trigger is connected with two NAND gates. One of the input terminals of each two NAND gates is connected one of the two contact points of a micro-switch on the main car door. The output signals of the two NAND gates are used for driving two negatively triggered mono-stable circuits each with a different operation time; an remote control device can send out a signal to the receiving circuit so as to automatically control the operation of the locking devices of the car doors. Since the operation time of the two negatively triggered mono-stable circuits is different, they can drive a indicating lamp which will have different blinking times to indicate the operation state of the locking devices.
