Description

A kind of multifunctional theft alarm for automobile

Technical field

The utility model relates to a kind of warning howler, specifically a kind of multifunctional theft alarm for automobile.

Background technology

Along with the standard of living of people improves constantly and China's accession to WTO, the price of common automobile is more and more lower, the owning amount of private car is also in continuous increase, a large amount of automobiles has brought a lot of convenience, but meanwhile, car thief also increases gradually, although market has occurred a lot of burglary-resisting installation, but steal driver's section constantly to upgrade, it is tending towards high-technicalization gradually, and major part burglar alarm adopts infrared alarm to trigger, sensitivity is low, complex structure, it is easy to be discovered by robber and crack, and existing warning howler adopts chip structure control mostly, it can only send short-distance alarm, and its function is comparatively single, anti-theft effect is undesirable.

Practical novel content

The purpose of this utility model is to provide a kind of multifunctional theft alarm for automobile, to solve in above-mentioned background technology the problem proposed.

For achieving the above object, the utility model provides following technical scheme:

A kind of multifunctional theft alarm for automobile, comprises power supply E, relay J, chip IC 1 and antenna B, the positive pole connecting valve S1 of described power supply E, the other end of switch S 1 connects the contact J-2 of relay J, relay J, the other end of resistance R1 and electric capacity C6, resistance R1 connects the control pole of electric capacity C6 and unidirectional thyristor Q1, and the other end of relay J connects the anode of unidirectional thyristor Q1, and the negative electrode of unidirectional thyristor Q1 connects electric capacity C3, electric capacity C5, inductance L 2, pressure switch A, door control switch P, the contact J-1 of relay J and the pin 2 of chip IC 1, the other end contact resistance R4 of the contact J-2 of relay J, electric capacity C4, the pin 8 of inductance L 1 and chip IC 1, the pin 3 of chip IC 1 connects electric capacity C2, the base stage of the other end connecting triode V1 of electric capacity C2, the other end of resistance R4 and the other end of electric capacity C3, the collector electrode of triode V1 connects the other end of electric capacity C4, the other end of inductance L 1, the emtting electrode of electric capacity C1 and antenna B, triode V1 connects the other end of electric capacity C5, the other end of inductance L 2 and the other end of electric capacity C1, the model of described chip IC 1 is KD9561.

As preferred version of the present utility model: described relay J is normally opened contact rly..

Compared with prior art, the beneficial effects of the utility model are: the door control switch of the utility model multifunctional theft alarm for automobile employing hidden type and pressure switch are as triggering source, disguised high, not easily crack, it is provided with from lock module simultaneously, it can not be stoped to send remote alarm signal even if destroy triggering source once be triggered, therefore there is diverse in function, trigger advantage accurate and easy to use.

Accompanying drawing explanation

Fig. 1 is the schematic circuit of multifunctional theft alarm for automobile.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only the utility model part embodiment, instead of whole embodiments. Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Referring to Fig. 1, a kind of multifunctional theft alarm for automobile, comprises power supply E, relay J, chip IC 1 and antenna B, the positive pole connecting valve S1 of described power supply E, the other end of switch S 1 connects the contact J-2 of relay J, relay J, the other end of resistance R1 and electric capacity C6, resistance R1 connects the control pole of electric capacity C6 and unidirectional thyristor Q1, and the other end of relay J connects the anode of unidirectional thyristor Q1, and the negative electrode of unidirectional thyristor Q1 connects electric capacity C3, electric capacity C5, inductance L 2, pressure switch A, door control switch P, the contact J-1 of relay J and the pin 2 of chip IC 1, the other end contact resistance R4 of the contact J-2 of relay J, electric capacity C4, the pin 8 of inductance L 1 and chip IC 1, the pin 3 of chip IC 1 connects electric capacity C2, the base stage of the other end connecting triode V1 of electric capacity C2, the other end of resistance R4 and the other end of electric capacity C3, the collector electrode of triode V1 connects the other end of electric capacity C4, the other end of inductance L 1, the emtting electrode of electric capacity C1 and antenna B, triode V1 connects the other end of electric capacity C5, the other end of inductance L 2 and the other end of electric capacity C1, the model of described chip IC 1 is KD9561.
