Embodiment
Describe embodiment in detail by reference to the accompanying drawings.A kind of starter relay of automobile-used band double protection functions, by Bakelite Cover 1, duplicate protection module 2 and starter relay 3 are formed, the side of starter relay 3 is fixed with Bakelite Cover 1 by installation screw 4, Bakelite Cover 1 has vertical groove 5, the Bakelite Cover 1 of vertical groove 5 side is provided with duplicate protection module draw-in groove 6, the both sides of vertical groove 5 are respectively equipped with unwrapping wire groove 7 and terminals, duplicate protection module 2 is fixed in duplicate protection module draw-in groove 6 by 906 casting glues, many lead-in wires in duplicate protection module 2 draw respectively by unwrapping wire groove 7 receives corresponding terminals, wherein the first terminals 8 and the common external ignition switch in relay coil one end, second terminals 9 connect the relay coil other end, 3rd terminals 10 are by trip bolt connection metal frame ground, the outside of duplicate protection module 2 is provided with lug plate 11, the external generator neutral point of this lug plate 11.
Two fast circuit theory of mould of protecting of the present invention is: Q1 is N-type MOSFET pipe, and grid connects operational amplifier 1 and 7 pin, and source electrode connects negative pole, and drain electrode connects the coil of starter relay.
P1 dual operational amplifier, 8 pin of operational amplifier are powered, 4 pin ground connection, 3 pin and 5 pin are operational amplifier positive input, 2 pin and 6 pin are the reverse input end of operational amplifier, 1 pin and 7 pin are respectively the output of operational amplifier, and D1 function absorbs the anti-induction electromotive force that starter relay coil produces when disconnecting, i.e. fly-wheel diode function.
When starting voltage is added to positive pole, R1 and R2 dividing potential drop, control pole to Q1 to power, make Q1 conducting, control starter relay adhesive conducting, starter is started working, longly starter is burnt for preventing the starting time, charge to C1 through R5, when charging voltage is greater than the voltage of 1 pin and 7 pin, 1 pin and 7 pin voltages become 0 volt, Q1 ends conducting, starter relay disconnects, reach the object of protection starting machine, R3 and D2 function prevents 2 pin charging voltages and 1 pin, when 7 pin voltages occur critical, occur that the continuous adhesive of starter relay disconnects phenomenon, D4 and R6 forms a quick discharging circuit, prevent first time from not starting successfully, the second time starting time shortens phenomenon.
Generator neutral point N hold or generator W power-off pressure input through D3 carries out rectification and voltage isolation, charge to C2 through R4 current limliting, when 6 pin voltages be charged to be greater than 1 pin and 7 pin voltage time, Q1 end conducting, starter relay disconnection, reach the object of protection starting machine.R7 and D5 forms the quick discharging circuit of a generator neutral point, prevent flame-out after, call a taxi again at once and occur that protection disconnects phenomenon in advance.R8 current-limiting resistance, D6 are LED light-emitting diodes; detect generator neutral point operating state at any time; convenient observation and maintenance; operationally, generator neutral point N or W end has high voltage to input to engine, then when calling a taxi, Q1 just ends conducting; starter relay can not adhesive; there will not be restarting phenomenon, can prevent engine counter drag starter and cause burn starter phenomenon, reach the object of protection starting machine.This protection and protection above do not conflict, as long as there is a road protection act, Q1 just ends conducting, and starter relay disconnects, and reaches the object of duplicate protection starter.
The defencive function sections in series of duplicate protection module of the present invention, in the middle of the coil of starter relay, realizes defencive function with the break-make of control coil earth terminal.The feeder ear of duplicate protection module is connected with the starting end of starter relay coil, for powering to protection module.Whether generator neutral point in the signal termination car of duplicate protection module, detect vehicle normal starting or running.The earth terminal of duplicate protection module is by starter relay metal shell ground connection.
During starting; power to duplicate protection module second terminals and relay coil one end by ignition switch simultaneously simultaneously; before vehicle unstart that and if only if completes; duplicate protection module second terminals and the 3rd terminals are in on-state; moment relay coil other end is indirect earthed starts working for this; and this state maintains about 10 seconds the second terminals and the 3rd terminals disconnect; relay coil quits work; carry out protection starting machine with this to burn out because being energized for a long time, this is first heavily to protect.
Under normal circumstances; vehicle can complete starting about 3 seconds seconds; when normal working of engine; generating state can be entered by drive electrical generators; now generator neutral point there will be high potential; connected by wire and this high potential signal is passed to duplicate protection module lug plate, after now duplicate protection module second terminals and the 3rd terminals receive signal, time delay within about 2 seconds, off-state can be in, until this blackout always.After vehicle has been started in 10 seconds, just time delay about 2 seconds is power-off of starter; to ensure that vehicle is in engine operation process; driver and conductor touches ignition switch by mistake also can not make starter work, effectively can prevent that engine is counter holds up motivation, and this is second heavily to protect.
Duplicate protection module of the present invention is insulated by 906 casting glues, fix, dispel the heat, waterproof, sealing, prevent protection module from making moist, intake, shake, temperature is too high and cause fault.
The benefit that starter relay brings after adding duplicate protection module: (1) adds the starter relay of duplicate protection module, starting time controls at about 10 seconds by protection module, automatically can disconnect starter relay more than 10 seconds, avoid the starting time longly to burn out starter, (2) starter relay of duplicate protection module is added, another protection is that engine operation prevents reignition from protecting, vehicle is in mobile process, engine running is driven by starter, driven by engine electrical power generators simultaneously, when after engine start success, rotating speed reaches 500 turns, when generator neutral point voltage reaches about 12V, protection module time delay disconnects starter relay in 2 seconds automatically, can ensure that engine is in operation, starter can not work, prevent engine to be in operation and occur reignition phenomenon, effectively can avoid that engine is counter holds up motivation, thus decrease the damage of starter and burn.
Embodiment above describes general principle of the present invention, principal character and advantage; the technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; under the scope not departing from the principle of the invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the scope of protection of the invention.
