The utility model is characterized in that an AND circuit integrated package IC< 1 >, a delaying integrated package IC< 2 >, a trigger IC< 3 > and an electronic switch are orderly and electrically connected; the contact of an actuator element is connected with an ignition circuit or an oil pump circuit in series; the IC< 1 >, the IC< 2 >, the IC< 3 > and the electronic switch Q < 1 > have the same working voltage V; a normally open reset switch S< 1 > is connected between one foot and the earth wire of the IC< 3 >; the earth wire of the IC< 1 > is connected with a button switch S< 2 > in series; the input end of the IC< 1 > is connected with an auxiliary power supply line. The utility model can cut off the power supply of an ignition device so the vehicle can not be ignited and started, and the vehicle is protected. The utility model has the advantages that the size is small; the reliability is high; the cost is low; the security is high, etc. The utility model can be widely used for various vehicles.
Description
The utility model relates to a kind of Plunder-proof device, particularly a kind of auto electronic antihijacking device.
Existing vehicle alarm device is mainly used in the anti-misfortune of vehicle, if the directly hand-held lethal weapon of hijacker is plundered automobile, the driver will be unable to cope with, and can only allow the robber catch up with and get off, and see that helplessly vehicle is driven away by the robber.
The purpose of this utility model is to provide a kind of good concealment, is quick on the draw, makes the motorist that the modularization auto electronic antihijacking device of a sense of security is arranged.
The purpose of this utility model realizes by following structure: the utility model is a kind of automobile-used antihijacking device, and it is by the AND circuit ic chip
1, the time-delay ic chip
2, binary pair IC
3, electronic switch is electrically connected in proper order, the contact of power element is connected on firing circuit or the oil pump circuit, IC
1, IC
2, IC
3, electronic switch Q
1Has identical operating voltage V, IC
3One draw be connected between angle and the ground wire and often open reset switch S
1, at IC
1Grounding jumper on the button switch S that connecting
2, IC
1Input end is connecting auxiliary power supply line.
The utility model is a kind of auto electronic antihijacking device, the input end of this device is connected to the positive pole and the negative pole of storage battery, and be connected with the ceiling light circuit with auxiliary power supply line, mouth is connected with ignition device or electric oil pump, the electronics package envelope is irritated into a little module and is positioned over the difficult arbitrarily position of finding in the car, the utility model has been removed the worry of chaufeur to vehicle safety, and the running of this device is full automatic.The utility model is because with electronics antihijacking device modularization, and can hide in car local arbitrarily as: in the storage battery, therefore anti-misfortune function of the present utility model obtains better protect.The utility model is to realize by the power supply that automobile igniter or oil pump are cut off in terminal one miniature reliability relay time-delay.Radical function of the present utility model is anti-the misfortune; no matter the hijacker starts car in any pressure mode; Plunder-proof device is promptly started working; when the vehicle ' time reaches 60S; this device is about to the power supply of ignition device and supplies with cut-out; though this moment, car load had electricity, automobile can't retrofire, has played the purpose of protection vehicle.It is little to the utlity model has volume, and characteristics such as reliability height, cost are low, confidentiality height are widely used in all kinds of automotive uses.
Fig. 1 is antihijacking device installation site figure.
Fig. 2 is an antihijacking device electricity principle sketch.
Fig. 3 is the utility model fundamental diagram.
Embodiment:
As shown in Figure 1, the electronics package envelope is irritated into a little module and is positioned over the difficult arbitrarily position of finding in the car.Antihijacking device as shown in Figure 2, it is by the AND circuit ic chip
1, the time-delay ic chip
2, binary pair IC
3, electronic switch is electrically connected in proper order, the contact of power element is connected on firing circuit or the oil pump circuit, IC

3, electronic switch Q
1Model be respectively 75LS5011, L272S, 75LS6744, BS170.
The utility model as shown in Figure 3, the utility model circuit has the integrated package of time action by an integrated package with ' thinking ' effect with one and electronic component that some are relevant is formed.The utility model need be connected with the 12V power supply of automobile, and is connected with auxiliary power supply line and the door lamp switch connected by ignition lock.As shown in Figure 2, door switch provides grounded circuit for gate light when car door opening, and door switch is in the 12V current potential when door is closed, and door then is zero volt when opening.Logic storage battery on this line is by diode D
2The anti-phase back of 13 pin that is locked to the logic integrated package had only when ignition lock is connected to the 9 pin while, just had on the auxiliary power supply line+12V voltage, then passed through D
3Be connected to 8 pin of logic integrated package.Under the normal starting state of automobile, i.e. when ignition lock connection car door was closed again, 10 pin of logical integrated circuit were output as high level.But if as long as a car door opening is arranged, integrated package 10 pin are exported with regard to vanishing.Timing integration block IC is coupled in this negative sense variation
2On, IC
2Pick up counting, the time is about 60 seconds.Work as IC
2Timing cycle when finishing, mouth produces a change pulse, makes IC
3Bistable circuit changes state, and it is Q that mouth becomes high potential by low voltage
1Excitation being provided, the relay normally closed contact is opened, is firing unit or oil pump circuit supply no longer just, therefore automobile is stopped.When pressing hiding reset switch S
1When making it closure, a negative going pulse that changes makes IC
3Output is low voltage by high-voltage variable, thereby release relay allows automobile to start once more.
