Description

The motorcycle anti-theft warning device

A kind of motorcycle anti-theft warning device belongs to the signalling apparatus technical field, is mainly used in motorcycle anti-theft and reports to the police.

Various antitheft alarm systems emerge in an endless stream in prior art.But mostly be bypassed on the car existing equipment need not, and the antitheft alarm system of setting up separately in addition.So the structure more complicated, the cost height is difficult for promoting, and also easy in addition stolen car people destroys, and makes it to lose anti-theft alarm function.

The purpose of this utility model is to provide a kind of and utilizes less components and parts that original electronic igniting circuit of motor bike and dynamic loud-speaker are transformed, make it to have anti-theft alarm function, not only simple in structure, firm, hermetically sealed, be difficult for destroyed, in case and alarm mechanism is destroyed falls, burglar-proof mechanism still is in the state that car can not be lighted a fire, therefore theftproof performance is reliable, and cost is low, easily the motorcycle anti-theft warning device of promoting.

Principle of work and mercury switch and silicon controlled characteristic according to the motorcycle electric ignition system, to the subject matter that exists in the prior art, basic design of the present utility model is: carry on the arm and connect an electric capacity at the R2 place in former known motorcycle electric firing circuit, in this circuit, set up simultaneously a fine motion automatic reset switch again by mechanical lock control, this is locked in and connects into the dead bolt ejection in the circuit is normal driving states, and the dead bolt withdrawal is the anti-theft alarm state; On the PC board of above-mentioned known circuits, increase a warning circuit of forming by alarm switch, mercury switch, resistance and silicon control in addition again.Fall in order to prevent that this device is destroyed, irritate with the epoxy resin envelope again after being fixed on above-mentioned mounted PC board in the iron-clad.

Of the present utility modelly be characterised in that described motorcycle anti-theft warning device is by the charge coil L1 on the magneto generator and trigger winding L2 and diode D1-D3, resistance R 1-R3, capacitor C 2, controllable silicon SCR 1 and high-tension coil B1 and handlebar electric lock K1 are installed in resistance R 2 two ends in the electronic igniting circuit on the bar printing wiring board according to the known former motorcycle electric firing circuit shown in accompanying drawing 2 tops and carry on the arm and connect a capacitor C 1 and refill the mouth that its open contact meets above-mentioned diode D1 according to anti-theft circuit shown in accompanying drawing 2 bottoms, its normally closed contact connects above-mentioned charge coil L1 and trigger winding L2 intermediate point, its intermediate point connected to chassis fine motion anti-theft switch K2 that automatically resets, so that even the cracksman has destroyed handlebar electric lock K1, also can guarantee charge coil L1 by K2 ground connection reliably, make the car can not normal ignition; Simultaneously on above-mentioned PC board, also mercury switch K4, resistance R 4 and the controllable silicon SCR 2 that alarm switch K3, its degree of dip can be regulated voluntarily by the car owner is housed according to as shown in Figure 3 warning circuit, the normally closed contact power connection positive pole of above-mentioned alarm switch K3, mercury switch K4 series resistance R4 connects the open contact of another termination K switch 3 of the control utmost point K4 of controllable silicon SCR 2, and the positive pole of the dynamic loud-speaker Y of the output termination motor bike of controllable silicon SCR 2, the continuous sounding of dynamic loud-speaker when body vibrations or degree of dip being changed with convenient cracksman.

Be that anti-this device is destroyed by the people, above-mentioned installation the PC board of electronic devices and components be fixed on that the back all seals with the epoxy resin perfusion together with above-mentioned K switch 2, K3 and K4 in the metal case.

The above-mentioned fine motion anti-theft switch K2 that automatically resets is controlled by a mechanical lock, and this is locked in and connects into dead bolt in the circuit and eject (when promptly locking) and be normal driving states, and dead bolt withdrawal (when promptly lock is opened) is the anti-theft alarm state.

The utility model has the advantages that: making full use of on the motor bike original parts increases seldom several parts again, simple in structure, it is few to spend, easily promote, all, be difficult for destroyed by epoxy resin perfusion sealing, even alarm mechanism is destroyed, metal case has been pried open, and charge coil still can make the car can not normal ignition by anti-theft switch failure-free ground connection, so theftproof performance is reliable especially.

Casing does not seal the monnolithic case scheme drawing of filling to accompanying drawing 1 for one of the utility model most preferred embodiment installs,

Accompanying drawing 2 is antitheft part circuit diagram,

Accompanying drawing 3 is the partly circuit diagram of reporting to the police.

1 charge coil L1 among the figure, 2 trigger winding L2,3 diode D1-D3,4 resistance R 1-R3,5 capacitor C, 2,6 controllable silicon SCR, 1,7 high-tension coil B1,8 handlebar electric lock K1,9 capacitor C, 1,10 fine motion automatic reset switch K2,11 alarm switch K3,12 mercury switch K4,13 resistance R, 4,14 controllable silicon SCR 2,15 motorcycle electric firing circuits, 16 anti-theft circuits, 17 warning circuits, 18 PC board, 19 motor bike dynamic loud-speakers, 20 mechanical locks.

With most preferred embodiment constructional feature of the present utility model further is summarized as follows in conjunction with the accompanying drawings: by charge coil L11, trigger winding L22, three diodes 3 of D1=D2=D3=1N400T, R1=10K, R2=2.2K, the electric capacity 9 that meets a C1=23f/16V is carried at R2 two ends in original circuit that three resistance 4 of R3=1K, C2=1.5f/400v 5, SCR1=BA/400V6 and high-tension coil B17 and handlebar electric lock 8 are installed according to known motorcycle electric firing circuit 15 again on the arm, and installs the fine motion anti-theft switch K2 that automatically resets on PC board again additional.
