Description

The electromechanical car alarm

The utility model relates to a kind of electromechanical car alarm.

The security relationship of automobile is stable to entire society, each rises and steals the car case is exactly a great criminal case, automotive safety has become the focal issue of government and people's concern, what existing vehicle anti-theft device generally all adopted is single mechanical anti-theft lock or single electronic anti-theft device, the former is nothing more than handle lock is arranged, foot-operated lock, protection defending lock, tyre lock, Cover lock for engine, this class mechanical anti-theft lock can not the detecting intrusion behavior and is sent alarm sound, the offender has grasped its structure, can utilize the special tool and the instrument of preparation, 3-5 minute at most, can successfully steal a car that burglary-resisting installation is housed in 18 seconds at least; Though latter's electronic anti-theft device has warning function, a little less than the anti-damage ability, and simple interest vibration sensor received signal, easily nondestructive concussion is received and report to the police.

The purpose of this utility model provides a kind of have antitheft detection performance and the strong electromechanical car alarm of anti-damage ability.

For achieving the above object, the utility model is taked following design plan: this electromechanical car alarm, form by protection defending lock, Cover lock for engine, detection alarm controller, establish a gear interface micro-switch in the described protection defending lock lock gall, this switch actuating signals is received by lead on the input terminal of detection alarm controller, and an output drive signal terminal of detection alarm controller connects on the driving switch of Cover lock for engine.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is gear lock construction scheme drawing (under the enforcement state)

Fig. 3 is the Cover lock for engine structural representation

Fig. 4 is a detection alarm controller line functional-block diagram

Fig. 5 is a detection alarm controller electronic-circuit diagram

As shown in Figure 1, the utility model is made up of protection defending lock 1, Cover lock for engine 2, detection alarm controller 3.

The structure of protection defending lock 1, Cover lock for engine 2 is referring to Fig. 2, shown in Figure 3, and this two class formations lock now has been widely used in the automobile, belongs to prior art, does not state tired herein.Its unique point is to establish an interface micro-switch in protection defending lock lock gall 101, lock hook 102 clutch actions cause interface micro-switch contact output signal, connect by lead on input terminal P3B, P3C, the P3D of detection alarm controller 3, connection therebetween also can realize by the grafting of connecting terminal block.The output drive signal terminals P 4D of detection alarm controller links to each other with the driving switch of Cover lock for engine by lead, also can realize that this driving switch places in the actuating mechanism 201 of Cover lock for engine by the grafting of connecting terminal block equally therebetween.

The electrical principles of detection alarm controller and scheme circuit such as Fig. 4, shown in Figure 5, what adopt is the electronic circuit of existing auto electronic Car Burglar Alarm, comprise a power supply voltage-stabilized power supply circuit unit, one CPU central processing unit U1, peripheral wireless electrolytic code loop unit U2 and driving circuit units U3, the composition of its circuit also is a prior art, be not repeated herein, its improvement is: direction that its cpu central processing unit is differentiated and mode and former electronic anti-theft device are antithesis, it is the input terminal P3B that the lead that draw protection defending lock inner boundary interface micro-switch contact is connect this control path, P3C, on the P3D, utilize the state that opens or closes of protection defending lock to go combination, and give CPU central processing unit this combination, by cpu power to P3B, P3C, P3D exports these signals to three line the insides of bonded assembly, it is not to have only positive electricity for these several lines, negative electricity, it provides a CPU numerical digit signal, this numerical digit signal composition is differentiated by CPU element, go out by the continuous feed signals of CPU, and backhaul signals is returned, could judge that protection defending lock is unlocking condition or shuts state, if the state of wanton destruction incoming signal, it will trigger warning at once under anti-theft state, thereby can realize the detecting to the protection defending lock situation.At the radio reception signal of decoding unit part, accept opening door of remote-control fully in addition, just give CPU signal after, the action that allows CPU can the direct controlling and driving central controlled lock open the door or to close the door, and can not go to trigger other situation.The another one Cover lock for engine also is to go to drive it by the CPU output signal.

For strengthening damage resistance, the alarming horn of this detection alarm controller is the alert loudspeaker of active anti-newspaper cutting.

During enforcement, protection defending lock locking gear handle, the detection alarm controller can be loaded in the operator's compartment, destroys this detection alarm controller for hindering criminal, and available Cover lock for engine pins its outer cover defence device.Also detection alarm controller installation site can be moved in the engine room, pin the driving engine chamber cap, cover can't be opened with Cover lock for engine.

The utility model has the advantages that:

1, adopts dynamo-electric combination, so that can make the best use of the advantages after the combination of pure mechanical lock of the prior art, electronic anti-theft device Keep away weak point.

2, owing to receive only protection defending lock latch hook mechanical action signal, this signal is more infallible, thereby avoids The wrong report situation of primary electron alarm take place.

3, because three kinds of devices organically combine use, even criminal destroys one or its two, not ruined temporarily device still can be worked, and postpones time of resisting, and improves theft-proof function greatly.

Claims (2)

1, a kind of electromechanical car alarm, form by protection defending lock, Cover lock for engine, detection alarm controller, it is characterized in that: establish a gear interface micro-switch in the described protection defending lock lock gall, this switch actuating signals is received by lead on the input terminal of detection alarm controller, and an output drive signal terminal of detection alarm controller connects on the driving switch of Cover lock for engine.

2, electromechanical car alarm according to claim 1 is characterized in that: the alarming horn of described detecting alarm is the alert loudspeaker of active anti-newspaper cutting.
