Abstract
The utility model relates to an anti-theft device of an automobile or a motorcycle. The anti-theft device consists of an anti-theft device switch (K2), a control circuit (1) and a high-voltage generating circuit (2). The anti-theft device switch (K2) is connected with a vehicle electric door, the control circuit (1) is connected with the high-voltage generating circuit (2) in parallel, the input ends of the control circuit (1) and the high-voltage generating circuit are connected with the anti-theft device switch (K2), the control circuit (1) consists of a control relay J and a diode (D1) connected with the control relay J in parallel, the control relay J controls the action of a normally open contact (J1-1), one end of the normally open contact (J1-1) is grounded, and the other end of the normally open contact (J1-1) is connected with a vehicle ignition coil (XD. The utility model has the advantages of simple structure, good reliability and no power consumption.
Description
The utility model relates to the anti-joyride device of automobile or motor bike.
Existing anti-theft device for vehicle mainly contains two types.One class is machinery or electronic lock, and another kind of is combined aural and visual alarm.The effect of machinery or electronic lock class Car Burglar Alarm is to stop vehicle launched, or is removed.Combined aural and visual alarm then is that feelings are stolen in report, draws back cartheft simultaneously with fear.At present, the Car Burglar Alarm of people's invention exists structure comparatively complicated shortcoming, especially machinery or electronic lock mostly.Combined aural and visual alarm then can only be reported robber's feelings, and can not thoroughly prevent theft.What more make people's worry is also usually to report by mistake, when wrong report takes place especially at dead of night, stir neighbours' uneasiness, and feelings in fact take place to steal.
The purpose of this utility model provides a kind of simple in structure, and is cheap, good reliability, the anti-theft device for vehicle of no power consumption.
The utility model is made up of Car Burglar Alarm switch, control circuit and high-pressure generating circuit.The Car Burglar Alarm switch is connected with the vehicle electric switch, and control circuit is in parallel with high-pressure generating circuit, and input end is connected with the Car Burglar Alarm switch; Wherein control circuit is formed by control relay J and with its diode connected in parallel D1, the action of control relay J control normal opened contact J1-1; The end ground connection of normal opened contact J1-1, other end vehicle ignition coil in parallel and horn for vehicle; The mouth of high-pressure generating circuit links to each other with car body.
Below in conjunction with embodiment of the present utility model and accompanying drawing thereof, describe its structure, principle of work and beneficial effect in detail.
Fig. 1 is a functional-block diagram of the present utility model;
Fig. 2 is the circuit diagram of the utility model embodiment.
As shown in Figure 1, 2, the utility model is made up of Car Burglar Alarm K switch 2, control circuit 1 and high-pressure generating circuit 2.Car Burglar Alarm K switch 2 is connected with vehicle electric switch K1, and control circuit 1 is in parallel with high-pressure generating circuit 2, and input end is connected with Car Burglar Alarm K switch 2; Wherein control circuit 1 is formed by control relay J and with its diode connected in parallel D1, the action of control relay J control normal opened contact J1-1; The end ground connection of normal opened contact J1-1, other end vehicle ignition coil XD in parallel and horn for vehicle Y.The utility model embodiment mesohigh generation circuit 2 is simple in structure, and it utilizes the collecting electrode oscillator coil of the high voltage package 1-3 winding of 14 cun vision receivers as silicon triode, and former high pressure output is as the high pressure output loop of high-pressure generating circuit 2.Outside former high voltage package, add one group of reversed trickler L3 again, with the frequency and the amplitude of control high-pressure generating circuit 2.The base bias loop is made up of base biasing resistor Rb, base stage reversed trickler L3, base bias capacitor C b, the frequency and the amplitude of its value decision high tension voltage producer.High-pressure generating circuit 2 among the utility model embodiment can normal starting of oscillation between input voltage 6-24V.Mouth VF is connected on the car body.
The utility model has utilized existing parts and the condition in the vehicle, helps cost-cutting.Car Burglar Alarm K switch 2 wherein should be installed in hidden place, and the connection lead of itself and vehicle electric switch also should be installed in hidden position in the vehicle.
When using the utility model, anti-theft switch is placed control position, at this moment, anti-theft device for vehicle is in readiness.Cartheft is wanted car is stolen, and generally all is attempt by the key provided for oneself or additive method with vehicle startup.If therefore cartheft is connected vehicle electric switch K1, then the power autonomous 12V of vehicle is added on the control relay J by Car Burglar Alarm K switch 2, thereby makes normal opened contact J1-1 closure, make vehicle ignition coil XD short circuit, and can not light a fire, making horn for vehicle Y conducting simultaneously and pipe, feelings are stolen in report.On the other hand, vehicle is power autonomous also to be added on the high-pressure generating circuit 2 by Car Burglar Alarm K switch 2, makes car body add high-frequency pulse voltage, makes cartheft can not contact car body, has defense function.
Want the readiness of freeing vehicle Car Burglar Alarm or be in the defence state, only need the disconnection of Car Burglar Alarm switch is got final product.
From the above as can be seen, the utility model is simple in structure, cheap; Have only when taking place to steal the car situation really, the utility model is just worked, thereby good reliability; When the utility model was in readiness, whole anti-theft device for vehicle did not have power consumption simultaneously.
Claims (1)
