Description

The anti-telltale of robbing of automobile

The utility model relates to the anti-telltale of robbing of a kind of automobile telltale, particularly automobile.

Present automobile anti-theft alarm aspect, existing car alarm, it is antitheft when automobile parking, when stealer touches automobile, the warning of promptly sounding of this burglar alarm.But anti-the misfortune when robbing of the automobile during Car Burglar Alarm is unsuitable for travelling used, when the robber utilized violence to rob car, above-mentioned Car Burglar Alarm was helpless, even patrol police or pedestrian are just near the car of being robbed during incident, also can't determine situation in the car, thereby the property damage that causes casualties.

The utility model purpose provides the anti-telltale of robbing of a kind of automobile, when it is robbed in running car, can send the anti-signal of warning of robbing of a kind of automobile, makes the pedestrian know that this car is robbed, with timely rescue.

The utility model is realized by following technical scheme.It comprises projector I, receptor II, control circuit III and filtering voltage stabilizer IV, Fig. 1 is its block scheme, send a kind of digitally coded radiowave by projector I, by receptor II this electric wave is received decoding back start-up control circuit I II, make it connect warning circuit and report to the police, between power supply V and receptor II, be connected with filter regulator circuit IV.Projector I is independent totally-enclosed module, in coder, projector and battery are arranged, before encapsulation, finish address code, module is equipped with button outward and is used for controlling optoacoustic and warns, this module is independent, volume is little, can be contained on one's body the driver, uses as remote controller.Receptor II also is the fully enclosed, in demoder, receptor are housed, before module assembling, finish address code.By automobile storage battery is power supply, and to receptor II and control circuit III power supply, automobile circuit under steam disturbs very greatly, and II is inapplicable to receptor, powers to receptor II after with the power supply voltage regulation filtering with filter regulator circuit IV again.Receptor II, control path III and filter regulator circuit IV all are encapsulated in the case, and this case is contained in shelter on the automobile, in automobile boot or car bonnet, with the connection of secretly sunkening cord.During use, 1. experience under the harm situation as the driver people that in car, is robbed, the button B of projector I can be pressed, make projector I send a kind of digital coding electric wave, after receptor II receives decoding, start the relay of this control circuit III, connect the light alerting system circuit, because light alerting system does not have any sound equipment, the ruffian is difficult for realizing in the car, but the outer personnel of car can find to succour.2. when being caught up with, the driver gets off, the ruffian robs car when runing away, the driver is out of danger, can press another button A of projector I again, send second kind of digitally encoded signal again, make the connection of warning of the sound equipment of control circuit III through receptor II, can also be with automobile distributor controlled supply disconnecton, automobile can not be travelled, and same time, sound are warned.

In sum, the utility model is owing to the employing wireless remote control transmits and receives, and remote controller is very little, is contained on one's body the driver, is difficult for warning rapidly under the discovery situation the ruffian, is convenient to arrest the ruffian; Receptor, control circuit and filter regulator circuit can be fitted together and be contained in the hidden part of automobile and be difficult for being found by the ruffian; Simple in structure, utilize automobile power source, during installation automobile mechanism there is not change.Therefore the utility model is the wireless remote controller that a kind of automobile can be warned when being held as a hostage immediately, can in time obtain relief rapidly, protects personal safety as well as the property safety effectively.

Do with embodiment below and specify.

Fig. 1 is a block scheme of the present utility model,

Fig. 2 is an electrical schematic diagram of the present utility model,

Fig. 3 is a scheme of installation of the present utility model.

Code name among the figure:

C1, C2 electric capacity, D1, D2, D3 diode, DW stabilivolt, IC1 receives decoder module, J1, J2, J3 relay, R1, R2, R3 resistance, T1, T2 aerotron, 15 turn marking lamps, 16 emergency flash of light characters, 17 telltale lamps, 18 sudden and violent flashing lights steep 19 turn signal flashers, 20 automobiles

As shown in Figure 1 and Figure 2, button A, the B of projector I send electric wave with different digital codings respectively, receive decoder module IC1 and control the circuit that terminal B, A are drawn with different digital codings respectively, the model of the reception decoder module IC1 that present embodiment adopts is MD KUAM, be with four mouths, only adopt wherein two.Projector I has four launching codes, only adopts two during use, and promptly button B is the light usefulness of warning, and another button A warns for sound or sound is warned and cut off the power supply for stopping and use.

Receptor II comprises reception decoder module IC1, under the effect of projector I electric wave, A from module I C1, the circuit that B two end points are drawn drives each relay connection through each resistance current limliting and the aerotron of control circuit III, to control each warning circuit, filter regulator circuit IV between power supply V and reception decoder module IC1, comprise capacitor C 1, C2, resistance R 1 and stabilivolt DW, R1 is associated between the end points VDD of V and IC1, be associated with an end connected to chassis capacitor C 1 and a stabilivolt DW at the R1 left end, right-hand member is connected to an end connected to chassis capacitor C 2, with the V power supply in addition behind the filtering voltage regulation as the power supply that receives decoder module IC1.Outage that control circuit III can be that light is warned, sound is warned or sound is warned is stopped etc., also can draw analogous conclusions to select for use and variously warn alone or in combination.When adopting light to warn, use the circuit of drawing from terminal B among the control circuit III, comprise aerotron T1 and relay J 1, J2 in parallel, between T1 and IC1, be connected with resistance R 2, and diode D1 is in parallel with relay J 1, and intrinsic turn signal flasher 19 circuit of the contact of J1 and automobile are connected, and this turn signal flasher 19 is the front and back turning indicator on the automobile 20, diode D2 is in parallel with relay J 2, connects with the circuit of telltale lamp 17 in the contact of J2; As Fig. 3, it is on glass that telltale lamp 17 is contained in automobile 20 interior rear windshields, adopt xenon flash lamp as sudden and violent flashing light bubble 18 in this lamp, and emergency flash of light character 16 and turn marking lamp 15, when automobile normal running, the action of this turn marking lamp 15 and 19 synchronized operations of motor turning flash light show to strengthen.This circuit operation makes its conducting for the signal that receives from IC1 affacts aerotron T1 from the B road in proper order, with relay J 1, J2 circuit turn-on, and with contacting, makes steering indicating light 19, and telltale 17 is connected and warned.When use sound is warned, the sound circuit working of warning of drawing then from terminal A, this circuit comprises aerotron T2 and relay J 3, between T2 and IC1, be associated with resistance R 3, diode D3 is in parallel with relay J 3, the open contact of J3 connect with the sound circuit of warning, and this loudspeaker of warning can also can adopt alarming horn to be contained in (not shown) on the automobile with original on the automobile.Also the normally closed contact of relay J 3 can be connected with automobile distributor controlled power supply simultaneously, to cut off automotive ignition system.
