Description

Automobile hedging, antihijacking device

The utility model belongs to a kind of automobile Plunder-proof device, particularly a kind of automobile hedging, antihijacking device.

Traditional automobile Plunder-proof device, all be by lock stopping switch Control of Automobile ignition system is set, and switch is placed on car door or shelter, in case found just can remove anti-misfortune measure by the people, even criminal can't find, in vehicle traveling process, the driver is when having perceived dangerous situation or robber and implemented to rob garage and be, under robber's violence monitors, can't go automobile to be stopped by the lock stopping switch at all, therefore, by the lock stopping switch is set, no matter how hidden its position is, in fact all do not have anti-misfortune effect.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of simple in structure, lock car mode is hidden, can really play anti-misfortune effect and safe and reliable automobile hedging, antihijacking device.

The utility model is achieved in that it has an ON-OFF control circuit that is made of aerotron and relay, its special character is this automobile hedging that is linking to each other with the electric automobile horn electrical signal, the input end of antihijacking device, by filtering, behind the clamped circuit, receive the trigger end of counting machine, the output control terminal of counting machine connects ON-OFF control circuit, be used for when reaching the predetermined trigger number of times, get by counter controls ON-OFF control circuit repeat circuit coil, flame-out with the Control of Automobile ignition system, at the guarantor position of counting machine end, be connected to another contact of relay between power supply and the ground, constant to keep the output state of counting machine after the relay adhesive, the counting end of this counting machine before the output control terminal of counting machine (removes Q ₀End), be connected on the input end of time-delay clear circuit by diode, and the clear terminal of its output termination counting machine, the Q of described counting machine ₀Terminate at the control end of time-delay clear circuit, be used for after counter O reset, the time-delay clear circuit is resetted, to prevent when not reaching the predetermined trigger number of times, causing misoperation.

According to above-mentioned automobile hedging, antihijacking device, be connected to the wireless remote control receiver module at the input end of ON-OFF control circuit, and by the control of remote control transmitter module, with its anti-misfortune and anti-theft feature of further realization.

The utility model has the advantages that simple in structure, safe and reliable, because this automobile hedging, antihijacking device adopt and press the electric impulse signal that loudspeaker produce and come the Control of Automobile ignition system, therefore, its mode of operation is hidden, be difficult for discovering for the robber, thereby realize hedging, the anti-function of robbing,, can further realize anti-misfortune, anti-theft feature by remote control circuit is set.

The drawing explanation:

Fig. 1 is the schematic circuit diagram of this automobile hedging, antihijacking device.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in the figure, this automobile hedging, antihijacking device have a power end B and input end A,, behind wire fuse BX, be respectively counting machine 1 (adopt 4017) and power through voltage stabilizer (7806) after, for remote control receiver module 4 (adopting TWH9238) at power end B, at input end A through capacitor C ₁Filtering reaches by diode D ₁, D ₂After the clamped circuit of forming is clamped, link to each other with triggering (CK) end of counting machine 1, at the Q of counting machine 1 ₁～Q ₄End is respectively by diode D ₃～D ₆With by resistance R ₁, adjust resistance W, aerotron VT, capacitor C ₂The input end 7 of the time-delay clear circuit 2 that constitutes links to each other, and the mouth 6 of time-delay clear circuit 2 links to each other the Q of described counting machine 1 with CL (zero clearing) end of counting machine 1 ₀Terminate at the control end 8 of time-delay clear circuit 2, be used for when automobile normal running, blast the horn (below 4 times the time) is counting machine 1 time-delay zero clearing, prevents that blast the horn causes misoperation again and automobile is pinned the output control terminal Q of described counting machine 1 ₅Connect by Darlington transistor T, relay coil J and protection diode D ₇The ON-OFF control circuit 3 that constitutes is with the mouth-Q of cause counting machine 1 ₅The mode of operation of end master cock control circuit 3, and then by the contact J of relay J wherein ₁The mode of operation of Control of Automobile ignition system, another contact J of relay J ₂Being connected on counting machine 1 protects between position end EN, power supply E and the system's ground wire, with after the relay J adhesive, it is constant to make counting machine 1 keep output state, (only after cutting off general supply E, could start once more, the remote control receiver module 4 that also is connected to by remote control transmitter module 5 (adopting TWHx) control at the input end 9 of described ON-OFF control circuit 3 (adopts TWH ₉₂₃₈), be used for realizing the remote control control of automotive ignition system, with the anti-misfortune and the anti-theft feature of further this device of realization.

When actual installation, power end B, the E of this device connect automobile power source, and this device is installed in shelter in the cover, and input end A connects the electrical signal of dynamic loud-speaker, the contact J of relay J ₁Be serially connected in the automotive ignition system.

1, hedging, the anti-function of robbing:

When real-world operation, if kidnapping Che Shihuo driver, the robber has a premonition when the interior passenger of car is suspicious, can select suitable highway section, connect by No. 5 loudspeaker counting machine 1Q ₅End output high level makes ON-OFF control circuit 3 conductings, by relay J contact J ₁The Control of Automobile ignition system is flame-out; If car when having been snatched away, in active distance, by remote control transmitter module 5 control receiver modules 4, turn-offs ON-OFF control circuit 3, automobile flameout then, and can't restart; (if want to restart, open cover, disconnect this device power supply, and start a car again can restart.)

2, anti-theft feature: during as if automobile parking, turn-off, also can play antitheft effect by remote control module 5 control ignition systems.

3, false action-proof function: when normal driving, when blast the horn is in 4 times, counting machine 1Q ₁～Q ₄End is successively to capacitor C in the time-delay clear circuit 2 ₂Charging through schedule time during to assigned voltage, makes counting machine 1 zero clearing, simultaneously, and Q ₀End output high level makes aerotron VT conducting, and capacitor C ₂Discharge through its C-E utmost point at once, thereby time-delay clear circuit 2 is restPosed, prepare for count next time.

According to actual needs, also can set pre-determined number and be 4,6 etc., as long as correspondingly with the Q of counting machine ₄, Q ₆End gets final product as output control terminal, and Q ₀～Q ₃End or Q ₀～Q ₅The connection of end is with Q among the embodiment ₀～Q ₄The connection of end.
