Description

Delay starting identification ignition device for vehicle

Affiliated technical field

The present invention relates to the ignition start device of igniting system for motor vehicle, particularly can make the starter motor automatic time delay close with engine operation after the protective gear of closing automatically.

Background technique

The igniting process of Motor Vehicle is after firing switch lock is opened, screw key connects the starter relay control end with power supply, by starter relay the storage battery line is connected the starting power supply guide line, make starter motor work, when motor is difficult for work because of other reason, often start for a long time continuously, this is for starter motor, meeting works long hours because of big electric current, and causes very big injury, and after engine start, as can not be in time with the key return, can cause starter gear wearing and tearing and engine ring gear to damage again, influence later starting quality, this is inevitable for the beginner.

Adopt the delay technique of Augusts 10 in 2000 " warning delayer ZL00215841.8 " that the Japanese proposes for this reason in person, proposed the scheme of " automatic identification ignition switch for motor vehicle ZL022120149 " on January 7th, 2002.But this delay technique in use, can only be that delay capacitor triggers charging by trigger switch, if Motor Vehicle is not changed mode of operation, with the traditional approach igniting, the time-delay purpose of this patent can't be implemented.

Patent CN2460737Y (applying date 200.11.22) discloses a kind of startup protector; disclosed technology is that the delay circuit by RC or time-base integrated circuit 555 or integrated fortune side (comparator) composition comes the control ignition time when igniting; the principle of RC be after slowly charging by electric capacity when greater than voltage-stabiliser tube DW breakdown voltage; voltage-stabiliser tube DW is punctured; make compound transistor VT1, VT2 conducting make relay work, disconnect starting power supply.This scheme that electric capacity is slowly charged puncture conducting composite pipe behind the voltage-stabiliser tube, have circuit complicatedly fall behind, unreliable.Shortcomings such as element weak point in working life, voltage and environmental requirement height.

Goal of the invention

To be exactly that design is a kind of do not change traditional firing mode to purpose of the present invention, each igniting time delays in accordance with regulations stop, light a fire successfully automatic termination, can't relight, the simple and reliable delay starting identification ignition device for vehicle of circuit.

Summary of the invention

The present invention realizes by following scheme: delay starting identification ignition device for vehicle, the delay circuit of forming by triode, electric capacity, resistance that comprises that starter relay and starter relay control end connected, it is characterized in that: at delay circuit, the charging end of electric capacity, there is a normally closed relay can give the electric capacity momentary charge, the normal-closed end of charge relay is electrically connected the electric capacity charging end, the end of convert of charge relay is electrically connected charge power supply, and charge relay control end positive electrical connects igniting switch starting power control line.

When delay circuit adopts the NPN triode, the anodal igniting switch starting power control line that is electrically connected with charge relay control end positive pole and end of convert of starter relay control end, the NPN transistor collector connects starter relay control end negative pole, connect capacitance cathode behind the NPN transistor base serial resistance, the electric capacity negative pole and connect the NPN transistor emitter after be electrically connected generator tutorial light negative signal line, the charge relay normal-closed end is electrically connected between capacitance cathode and the resistance, and charge relay control end negative pole also connects generator tutorial light negative signal line simultaneously.

When screw key was piloted engine, ignition switch C end had electricity, and the charge relay normal-closed end has electricity, because generator tutorial light negative signal tape has the negative electricity signal, and the electric capacity charging, charge relay work normal-closed end disconnects.Delay circuit is connected, starter relay work.Screw key is as return not, and ignition switch C end has electricity all the time, and charge relay is worked all the time, and normal-closed end disconnects all the time, just can quit work after the starter relay time-delay expiration.After engine operation, generator tutorial light negative signal line, negative electricity blackout.Starter relay and charge relay be return simultaneously, and starting circuit is closed.Even if ignition switch C end has electricity, starter motor can not worked yet.

Because some heavy vehicle when starting, needs the control end negative pole of control starter relay to confirm,, and set a negative pole control output line so delay circuit can adopt the PNP triode.

When delay circuit adopts the PNP triode, the PNP transistor emitter is connected igniting switch starting power control line with charge relay control end positive electrical, connect the electric capacity negative pole behind the PNP transistor base serial resistance, capacitance cathode connects the PNP transistor emitter, the charge relay normal-closed end is electrically connected between electric capacity negative pole and the resistance, the PNP transistor collector connects starter relay control end positive pole, starter relay control end negative pole connects generator tutorial light negative signal line, the charge relay end of convert and connect the control end negative pole after be electrically connected the negative power supply control switch.

After the negative power supply guide line was connected negative power supply, when screw key was piloted engine, ignition switch C end had electricity, and capacitance cathode has electricity, and the charge relay normal-closed end is electrically connected negative power supply, and after the electric capacity charging, charge relay work normal-closed end disconnects.Delay circuit is connected, starter relay work.Screw key is as return not, and ignition switch C end has electricity all the time, and charge relay is worked all the time, and normal-closed end disconnects all the time, just can quit work after the starter relay time-delay expiration.After engine operation, generator tutorial light negative signal line, negative electricity blackout.The starter relay return, starting circuit is closed.Even if ignition switch C end has electricity, starter motor can not worked yet.

Just know with crossing above design, delay starting identification ignition device for vehicle of the present invention, really have and do not change traditional firing mode, each spark delay stop, light a fire successfully automatic termination, can't relight, advantage such as simple and reliable, the wide accommodation of circuit.
