Abstract

The utility model provides an electromagnetic automatic door lock opening switch for an automobile and an electronic central control lock, which is composed of a transmission switch and a control circuit, wherein, the transmission switch is formed by inserting a movable iron core in the middle of a coil with an inner layer of winding and an outer layer of winding, and the iron core can be moved to drive an automobile door to open or close via a connecting rod; the control circuit is composed of an unlocking delay circuit, a central control locking circuit, a trigger moment conducting drive circuit and an attraction circuit. The utility model has the advantages of few components and low cost, and the utility model which does not need gear transmission reduces mechanical failure. The control circuit is reasonable and simple, and a driver can control automobile doors and a rear box to open and close in a centralized way. The utility model which replaces the existing central control locks is suitable for being installed on automobiles of various models.

Description

The electromagnetic type automobile automatic door lock is opened switch and electronics central controlled lock

Affiliated technical field

The utility model belongs to a kind of auto parts and components, particularly a kind of switch of automatic control vehicle door lock and control circuit thereof.

Background technology

Existing arrangements for automotive doors, back box lid will be opened and lock by pulling manually, and other all locks are decided mechanism, are locked mechanism outward and central locking control is formed by handle, outer handle, interior door button in car door lock tapered end, the car door lock.There is following defective in they in practical operation with in using: when removing the car door locking mechanism, can not spur the interior handle or the outer handle of car door simultaneously, can not spur the interior handle or the outer handle of car door earlier, and then remove the car door locking mechanism.Otherwise, can cause the car door locking mechanism can't remove, can't open, and can damage door-opening mechanism.Therefore must open car door according to the step of opening car door after unlocking earlier again.

The utility model content

The purpose of this utility model be to provide a kind of building block few, control easily the electromagnetic type automobile automatic door lock and open switch and electronics central controlled lock, car door is shaken hands outward to replace, interior handle and car door locking mechanism, and can replace the mechanical type central locking control fully.But shake hands inside and outside when the utility model is installed, should removing former car door locking mechanism and car door earlier.

For achieving the above object, the utility model has adopted following technical scheme: the electromagnetic type automobile automatic door lock is opened switch and electronics central controlled lock, comprise transmission switch and control circuit, its technical characterictic shows: the transmission switch is a group coil 1 and organize coil 2 outward in the coiling in magnetic conductive shell 8, removable iron core 6 is equipped with in the centre, removable iron core 6 is equipped with back-moving spring 7, connecting rod 4 is equipped with on top, connecting rod 4 is opened pull bar with lock and is connected, inside and outside two groups of coils all have two taps to draw from the wire hole of shell bottom 10, are connected with control circuit; Control circuit is made up of the delay circuit of unblanking, central controlled lock circuit, triggering moment on-state drive circuit and attraction circuit; The delay circuit of unblanking is made up of a duplex trigger switch, motor power switch, capacitor and relay; The central controlled lock circuit is made up of a trigger switch; Triggering moment on-state drive circuit is made up of trigger switch, safety switch, capacitor, resistance and a relay and interior winding coil; Attraction circuit is made up of relay, outer winding coil and capacitor.

Good effect of the present utility model is: the transmission switch adopts parts such as inside and outside two-layer winding and removable iron core to form, and does not need gear drive, has reduced mechanical breakdown, and Circuit Design is reasonable, and circuit is simple and reliable, is convenient to maintenance.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model embodiment transmission switch junctions composition.

Fig. 2 is the circuit diagram of the same embodiment control circuit of the utility model.

In Fig. 1, group coil in 1,2. outer group coil, 3. mounting bracket, 4. connecting rod, 5. link lock jack panel, 6. removable iron core, 7. back-moving spring, 8. magnetic conductive shell, 9. in not magnetic conduction support, 10. shell bottom.

The specific embodiment

An embodiment of the present utility model is made of jointly the transmission switch of Fig. 1 and the control circuit of Fig. 2.Control circuit is by the input power supply, the delay circuit of unblanking, and middle control circuit, triggering moment on-state drive circuit and attraction circuit are formed.Wherein, the delay circuit of unblanking is by car door lock duplex trigger switch K1, K2, motor power switch K3, and capacitor C1 and relay J 1 are formed.By car door lock duplex trigger switch K2 and motor power switch K3 control relay J1 working power, be J1K to inductive switch, J1K closure when K2 or K3 are closed; When disconnecting, K2, K3 form a delay circuit by capacitor C1 and relay J 1.Middle control circuit is made up of K4, can directly control the working power of triggering moment turning circuit and attraction circuit.Triggering moment on-state drive circuit is by parking brake safety switch K5, trigger switch K6, and resistance R 1, capacitor C2, relay J 2 and interior winding L 1 and contact protection capacitor C 3 are formed.When stopping, parking brake tension, safety switch K5 closure (during driving, loosen parking brake, K5 disconnects door open switch).When inside and outside when pressing car door, door contact interrupter K6 closure, R1, C2 composition moment turning circuit makes relay J 2 moments work, and winding coil L1 work in the inductive switch J2K conducting is produced high-intensity magnetic field, attract moving of removable iron core, drive the connecting rod 4 that is connected with the car door opening pull bar and make car door opening.Attraction circuit is made up of relay J 3 and contact protection capacitor C4; relay J 3 work in door open switch K6 closure; the outer winding coil L2 work of inductive switch J3K conducting is produced the adhesive of keeping removable iron core than low-intensity magnetic field; make car door lock be in opening always; door open switch K6 disconnects, and magnetic field disappears, and removable iron core resets under the effect of return spring 7; be in the lock state for the treatment of, promptly can doors locked with closing of the door.

Can connect other door control circuit at K4, K5, K6 place: as Fig. 2-B, its process is the same.The utility model unlatching car door operating principle is as follows: (1) opens duplex trigger switch K1, K2 when the driver opens the lock with the key, relay J 1 work when K2 connects, switch J1K closure, K switch 1 direct triggering moment turning circuit and attraction circuit make this car door opening, other car door must be pressed corresponding switch open, as K6.(2) when running car arrival destination: the tension parking brake, safety switch K5 closure, press door contact interrupter K6, open car door, K3 disconnects in the capacitor C1 generation discharge process short time and keeps relay J 1 work when killing engine power switch, C1 discharge off, relay are opened at each car door of J1K disconnection closing automobile and just can be automatically locked.(3) when the automobile stop off, must strain parking brake, safety switch K5 closure, each car door is pressed each and can freely be opened inductive switch or open corresponding car door by the driver by middle control K switch 4.
