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
