Description of drawings:

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is the engine stop schematic circuit diagram of at present popular distance type Car Burglar Alarm.

The specific embodiment:

According to the ignition principle that exchanges the vehicle of lighting a fire as can be known, at the firing unit energize and when ignition signal is arranged, have only flame-out line not have negative electricity or positive electricity (using logical negative electricity to make it not light a fire usually), car just can not normally start, therefore, be cut off at anti-theft state, power supply, the electric switch locking wire is cut, and (or electric door lock is destroyed, the destroyed back of electric door lock all is that the negative electricity of firing unit is cut off usually) and firing unit have under the normal again situation of power supply and ignition signal, the flame-out line bonding (negative electricity is arranged) of guarantee point firearm, vehicle just can not start.According to the use case that exchanges the vehicle of lighting a fire as can be known, this vehicle can there be under the situation of electricity at storage battery, (electric door lock is screwed onto the ON position to open electric door lock, this moment, the flame-out line of firing unit did not have negative electricity, the ON line of electric door lock communicates with the main power line of electric door lock), with foot-operated sparking rod (manual activation vehicle), firing unit is powered (when making engine running with foot-operated sparking rod by the high-tension coil of special use, high-tension coil has electricity output at once, and charge coil also has electricity output simultaneously) vehicle just can normally start.According to above-mentioned ignition principle, use case and Fig. 2 the flame-out principle of Car Burglar Alarm as can be known, after this type of Car Burglar Alarm was split at power supply, the electric switch locking wire cuts off, with foot-operated sparking rod, vehicle just can normally start, the anti-theft feature inefficacy.

As shown in Figure 1, this is a schematic diagram of the present utility model, and wherein, the negative output line of electric door lock can be cut off or not cut off, and uses as the distribution that cooperates Car Burglar Alarm, and this line is open circuited, and open circuited electric door lock end does not influence function of the present utility model, and this end can not connect.Negative wire Y is connected with the negative pole of metallo-car shell or storage battery, the end of output line A is connected with the flame-out line X of firing unit, the negative output line of electric door lock just, the output pin E of the other end and relay J 1, the output pin I of relay J 2 is connected, the output pin D of relay J 1, the output pin H of relay J 2 is connected with negative wire Y, the ON line of electric door lock (electric door lock is positioned at the forward transportation outlet of ON position) is connected with C, this circuit is not having under the situation of positive supply, just the control pin of relay J 1 and relay J 2 does not have under the situation of electricity, output line A passes through the output pin I of relay J 2 forever, H obtains negative electricity (output line A have vehicle can not start under the situation of negative electricity) through the Y bonding again, so, making first condition of the disconnected negative electricity of output line A is relay J 2 adhesives, make the output pin H and the I of relay 2 disconnect, therefore storage battery split after, the control pin J of relay J 2, K can not obtain positive electricity and negative electricity, relay 2 not adhesives, vehicle can not start, because the negative electricity of A separates with the negative electricity of electric door lock, so although the electric switch locking wire is cut off, the negative supply of electric door lock has broken, and the output line A that does not also influence Car Burglar Alarm has negative electricity.

In the normal use of vehicle, open electric door lock, because C links to each other with the forward transportation outlet of electric door lock, so C is by the ON line power supply of electric door lock, through time delay circuit, and maintenance certain hour after C advances electricity (for example 1 second, generally set 2 seconds, the function of reason and time delay circuit has explanation hereinafter) after, time delay circuit is for electrical equipment J2 power supply, if the control pin J of relay has connect the positive pole of power supply, then time delay circuit is to the control pin K of relay J 2 output negative electricity, otherwise, if relay control pin J has connect the negative pole of power supply, then time delay circuit makes relay 2 adhesives to the control pin K of relay J 2 output positive electricity, the output line A negative electricity that breaks, vehicle can normally start; When vehicle will stop working, the user closes electric door lock, and the ON line of electric door lock does not have output, and relay J 2 is not because control pin J or K have electricity and disconnect, and H, I engage, and output line A has negative electricity, and vehicle is normally flame-out; Under the situation of anti-theft alarm, internal control circuit provides power supply by L for relay 1, if relay J 1 control pin F is connected with the positive pole of power supply, which internal control circuit provides negative electricity to the control pin G of relay J 1, otherwise, if relay J 1 control pin F is connected with the negative pole of power supply, which internal control circuit provides positive supply to the control pin G of relay J 1, make its adhesive, output line A obtains negative electricity through negative wire Y bonding again by output pin E, the D of relay J 1, and vehicle can not normally start; When the user uses remote control to start vehicle, internal control circuit is relay J 2 power supply sources, if relay J 2 control pin J are connected with the positive pole of power supply, which internal control circuit provides negative electricity to the control pin K of relay J 2, otherwise, if relay J 2 control pin J are connected with the negative pole of power supply, which internal control circuit provides positive supply to the control pin G of relay J 1, make its adhesive, the output line A negative electricity that breaks, vehicle can normally start.

Above-mentioned time delay circuit, its function is: after C advances electricity, make relay J 2 adhesive at once, just allow relay J 2 adhesives after requiring C to maintain the input certain hour.Why want this function? reason is: after storage battery is split, electric door lock is also destroyed simultaneously, if this moment electric door lock ON line communicate with the main power line of electric door lock (electric door lock is screwed to the ON position by force), the sparking rod that steps vehicle as the robber makes engine running, at this moment, the charge coil of driving engine has electricity output, the main power line of electric current process electric door lock is to the ON line of electric door lock, arrive the ON line of Car Burglar Alarm then, C line just of the present invention, if there has not been the time delay circuit module, relay 2 just might adhesive (once be done overtesting in person, when with stepping sparking very energetically during rod, the voltage of the power lead of electric door lock can reach 6 to 8V, and this voltage is enough to make relay J 2 adhesives), but because driving engine is artificial running, its rotation time is limited, the output time of its charge coil is also just limited, generally is not more than 2 seconds, therefore, time delay circuit does not keep more than 2 seconds just not allowing relay J 2 adhesives at C, and one of percentage hundred guarantees that output line A have negative electricity.The delay time of above-mentioned time delay circuit (2 seconds) is just done the example introduction, does not represent position of the present invention, and final delay time uses with reality and is as the criterion.Time is oversize will to produce the problem that the user uses the vehicle inconvenience.
