Description

The anti-misfortune of self-propelled vehicle full automaticity, anti-stealing safety device

The utility model belongs to the anti-misfortune of a kind of self-propelled vehicle full automaticity, anti-joyride device, can be used on the various self-propelled vehiclees such as motor bike, automobile.

Popular in the market motor vehicle antitheft device kind is more, structure is different, and cipher lock type is arranged, the sound and light alarm formula, distance-type, wherein distance-type is current more advanced a kind of, but with regard to its utility function, still has several weak points:

1, the distance type Car Burglar Alarm that uses at present, degree of automation is also not high, still need operate pair machine (emitter) and realize a function such as warning, locking, startup by remote control, it is unhidden that machine is paid in this operated remote control, do not maintain secrecy, and easily found by the people, if suffer accident, can only allow the hijacker drive away, particularly the range of control of prior remote controller generally all in 1500 meters, is started to control to make and is used.

2, prevent to steal the way of car at present, be between ignition transformer primary winding and power supply, to insert a switch, the driver opens this switch, car can't be started, but the electric current of flowing through during switch closure reaches the 5--7 ampere, long-time use the easy sintering of switch contact together, cause because of can't cut power supply, and car is stolen.

3, existing remote theft-preventing apparatus structure is complicated, and the function of indicating is a lot, and in fact Shi Yong function seldom but costs an arm and a leg.

The purpose of this utility model provides a kind of simple in structure, controls hiddenly automatically, accurately and reliably, is easy to carry, cheap self-propelled vehicle is anti-ly robbed, the anti-stealing safety device.

The anti-misfortune of the utility model self-propelled vehicle full automaticity, anti-stealing safety device are made up of the main frame and the machine of paying, and ignition transformer, power supply and switch are arranged, and it is characterized in that the high-frequency signal transmission circuit that the machine of paying has adopted integrated package RCM-1A and power supply, switch to constitute; Main frame comprises high-frequency signal acceptor circuit, photoelectrical coupler and control circuit, the high-frequency signal acceptor circuit is made of integrated package RCM-1B, after the high potential of its 3 pin output is sent into photoelectrical coupler (P621B), output signal is sent into the power amplifier of aerotron G1, G2 formation and is connected on the control circuit that the relay K 1 on the collecting electrode is formed, the size of electric current in the contact K1-1 control ignition transformer of relay K 1.

Be connected to capacitor C 1 on 1 pin of integrated package RCM-1B over the ground and constitute time delay circuit in main frame high-frequency signal acceptor circuit, the size of capacitor C 1 requires and decides according to the car owner; At the two ends of the primary winding of ignition transformer, and be connected to short-circuit line, string has the normally closed contact K1-1 of relay K 1 and the resistance of little resistance in short-circuit line.

The utility model and existing Car Burglar Alarm relatively have following advantage:

1, owing to the integrated package that has adopted a pair of coupling in master, pair machine circuit, in the control circuit of main frame, adopted the size of current of primary winding of the normally closed contact control ignition voltage transformer of relay again, so when the driver who carries the machine of paying leaves the main frame certain distance that is contained in the car, main frame quits work automatically, the point of cutoff ignition source, control automatic, hidden, safety, be applicable to that the easily public taxi of crime and public security of upper and lower frequent, bad element, bank use with car.

2, integrated package RCM-1A in high-frequency signal transmission circuit and the acceptor circuit and RCM-1B are that pairing is used, and every pair frequency has nothing in common with each other, and in the frequency range of 250-350MH, it is some right to do, and the coding privacy functions is arranged like this.

3, adopt photoelectrical coupler that buffer action is arranged, prevent the self-propelled vehicle igniting, the peak inverse voltage electric current is to the impact of integrated package when flame-out.Frequency response simultaneously is also better, and having illumination to penetrate just has electric current output raising sensitivity.

4, the delay circuit of integrated package RCM-1B1 pin capacitor C 1 in host circuit in order that allow the hijacker drive away at short notice, is avoided the injury to the car owner.

Fig. 2 is the anti-misfortune of self-propelled vehicle full automaticity, anti-stealing safety device host circuit schematic diagram.

Fig. 3 is that the anti-misfortune of self-propelled vehicle full automaticity, anti-stealing safety device are paid machine profile scheme drawing.

Fig. 4 is that the anti-misfortune of self-propelled vehicle full automaticity, anti-stealing safety device are paid the machine circuit schematic diagram.

Among the figure, LED is the light-emitting diode that shows usefulness.

Embodiment: according to above-mentioned design plan, having manufactured experimently a protector integrated package frequency is 250MH, and postponing electric capacity C1 is 10 μ f/25V, and photoelectrical coupler is P621B.Aerotron G1 in the control circuit is 9011, and G2 is 9013, and relay is JZC22f, has been contained on oneself motor bike to try out, and now is illustrated in conjunction with the accompanying drawings (accompanying drawing is expressed as not mode of operation).

Energized, RCM-1B integrated package power supply is connected in relay K 2 work, the closed simultaneously machine switch S of paying, at this moment, when paying machine near main frame, the work of main frame high-frequency signal acceptor circuit is sent signal and is given photoelectrical coupler, control circuit, relay K 1 work, contact K1-1 cut-offs, it is elementary that voltage adds to ignition transformer, secondary output high pressure, and car can move; Otherwise when the machine of paying during away from main frame, the secondary no high pressure of the closed short circuit primary of contact K1-1 can not be lighted a fire.Show this protector automatically, accurately, reliably through on probation, when main and submachine left more than 50 meters, car can not start.Pay dynamo-electric source if cut off, car can continue the 7-10 second of travelling.
