Abstract

The utility model is an automatic antitheft device for motor vehicles. A remote control switch circuit is connected in series between an ignition circuit and the anode of a vehicle-mounted mains power. The remote control switch circuit at least has a wireless decoder, a triode and a relay. The output terminal of the wireless decoder is connected to the base electrode of a triode. The emitter electrode of the triode is connected to the cathode of the mains power. The collector electrode of the triode is connected to the cathode of the control terminal of the relay. The anode of the control terminal of the relay is connected to the anode of the mains power via a switch. The intermediate point of the relay switch is connected to the anode of the mains power. The normally-open contacts of the relay switch are connected to the ignition circuit of the vehicle. The antitheft device is expected to prevent theft of vehicles. The utility model is simple, convenient, flexible, reliable and practical for use and can protect the interests of the user.

Description

Self-propelled vehicle automatic antitheft device

Technical field

The utility model relates to a kind of self-propelled vehicle automatic antitheft device, is meant a kind of self-propelled vehicle automatic antitheft device by teleswitch and the common controlling machine motor-car of self-propelled vehicle key ignition wire connecting and disconnecting of the circuit especially.

Background of invention

At present, self-propelled vehicle is lost or the incident of being held as a hostage occurs repeatedly, and is because car owner's general idea causes under a lot of situation, stops to do shopping or get off such as: car owner and gets a thing and forget the lock car, and car is just driven away by the burglar in an instant, and at one's wit's end.Though, present anti-theft device for motor vehicle is varied, but can only work to locking the static car of parking mostly, car pulls key if the car owner forgets lock, or tackled by the people in the way of travelling, these Car Burglar Alarms are then of no avail, and cause loss economically even spiritual injury to the car owner.

Summary of the invention

In view of this; main purpose of the present utility model is to provide a kind of self-propelled vehicle automatic antitheft device; it is by setting up a remote control switching circuit between the ignition wire circuit of self-propelled vehicle and positive source; make the connecting and disconnecting of this teleswitch and self-propelled vehicle key common control live wire circuit; thereby play antitheft anti-gangster's effect; and use simply, convenient, flexible, reliable, practical, more can protect user's interests.

The utility model provides a kind of self-propelled vehicle automatic antitheft device, key is: be connected in series a remote control switching circuit between the positive pole of self-propelled vehicle ignition wire circuit and vehicle power, this remote control switching circuit comprises the wireless receiving decoder at least, an aerotron and a relay, the mouth of wireless receiving decoder links to each other with the base stage of aerotron, the emitter of aerotron connects power cathode, the negative pole of the collector connection relay control end of aerotron, the positive pole of relay control end connects positive source through a switch, the intermediate point of relay switch connects positive source, the ignition wire circuit that is connected to self-propelled vehicle normal battle of this relay switch.

This Car Burglar Alarm also is furnished with a wireless launcher to wireless receiving decoder transmission code word.

In addition, this Car Burglar Alarm is installed in that self-propelled vehicle is difficult for seeing or not easily detachable place, both has been difficult for destroyedly, uses safe and reliablely again, and maintenance is also convenient.

Description of drawings

Fig. 1 is a functional block diagram of the present utility model;

Fig. 2 is schematic circuit diagram of the present utility model.

The specific embodiment

Below in conjunction with drawings and the specific embodiments the utility model is further described in more detail.

Referring to shown in Figure 1; key of the present utility model is to set up a remote control switching circuit between self-propelled vehicle ignition wire circuit and positive source; send order for the decoder in the remote control switching circuit with the password electronic romote-controller; open with closed by remote control switching circuit control relay switch sections; and then control is switched on or switched off the ignition wire circuit; make the starting motor-driven vehicle igniting to control simultaneously with the remote controller of car key and teleswitch; Neither of the two can be dispensed; prevent that burglar or robber from stealing vehicle thereby reached, the purpose of protection car owner number one.

As shown in Figure 2, principle of work of the present utility model is such: when only lighting a fire with key, and K switch 1 closure, vehicle power is connected power supply, but the relay J of connectivity points live wire circuit is not closed, so self-propelled vehicle can not start; And this moment, the decoder A1 of remote controller in the utility model Car Burglar Alarm with teleswitch sends the unlatching password again, after decoder A1 identification is errorless, this decoder can make aerotron T1 conducting by give a signal, and then starting relay J work, make the relay J closure, firing point live wire circuit makes car can normally start, travel automatically.The remote controller that the utility model adopted is common password electronic switch, and the A1 in the present embodiment is wireless receiving decoder 9958C, and relay J is J2C-23FA.

In actual applications, as long as car owner's switch-off, K switch 1 and relay J all can disconnect, even in the stealer hand key is arranged, motor vehicle starting can't be driven away, because car key can only master cock K1 closure, and the relay of another control ignition line circuit normal operation is not connected yet.When car was robbed, the car owner can extinguish car, abandoned car afterwards and went, and the robber also can't drive away car.Even after running into some robber car being kidnapped, allow the car owner get off and do not allow it that car is flame-out, because annunciator of the present utility model adopts the wireless remote control mode to input password, therefore, the car owner can press remote controller equally after getting off, with flame-out order noiseless issue decoder A1, after the A1 decoding, control relay J disconnects, point of cutoff live wire circuit, the self-propelled vehicle auto shut down is stopped, and can't restart.

And Car Burglar Alarm of the present utility model is installed in and is difficult for finding or not easily detachable place, and the bandit can not be destroyed Car Burglar Alarm easily.As seen, practicality of the present utility model is extremely strong, and safe, reliable, easy to use, so, has not only protected car owner's interests, and also the gangster has made the time in order to arrest surreptitiously, has created chance.

The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
