Embodiment
Embodiment is described in detail with reference to accompanying drawing.A kind of automobile-used starter relay with double protection functions, by Bakelite Cover 1,
Duplicate protection module 2 and starter relay 3 are formed, and the side of starter relay 3 is fixed with Bakelite Cover 1, glue by installation screw 4
Vertical groove 5 is provided with wooden cover 1, duplicate protection module neck 6, vertical groove are provided with the Bakelite Cover 1 of the side of vertical groove 5
5 both sides are respectively equipped with unwrapping wire groove 7 and terminals, and duplicate protection module 2 is fixed on duplicate protection module card by 906 casting glues
In groove 6, more leads in duplicate protection module 2 are drawn by unwrapping wire groove 7 respectively is connected to corresponding terminals, wherein the first wiring
External ignition switch, the second terminals 9 connect the relay coil other end, the 3rd wiring jointly with relay coil one end at end 8
End 10 is provided with lug plate 11 by trip bolt connection metal shell ground connection, the outside of duplicate protection module 2, and the lug plate 11 is external
Generator neutral point.
The fast circuit theory of double protection mould of the present invention is：Q1 is N-type MOSFET pipes, and grid connects operational amplifier 1
With 7 pin, source electrode connects negative pole, and drain electrode picks up the coil of motor type relay.
P1 dual operational amplifiers, the 8 pin power supply of operational amplifier, 4 pin ground connection, 3 pin and 5 pin are that operational amplifier forward direction is defeated
Enter end, 2 pin and 6 pin are the reverse input end of operational amplifier, and 1 pin and 7 pin are respectively the output end of operational amplifier, D1 functions
Starter relay coil is absorbed in anti-induction electromotive force caused by disconnection, i.e. fly-wheel diode function.
When starting voltage is added to positive pole, R1 and R2 partial pressures, is powered to Q1 control poles, turn on Q1, control starts relay
Device adhesive turn on, starter start working, for prevent the starting time it is long burn starter, through R5 to C1 charge, when charging electricity
When pressure is more than the voltage of 1 pin and 7 pin, 1 pin and 7 pin voltages become 0 volt, and Q1 cut-off conductings, starter relay disconnects, and reaches protection
The purpose of starter, when R3 and D2 functions prevent that 2 pin charging voltages and 1 pin, 7 pin voltages from occurring critical, there is starter relay
Continuously adhesive disconnects phenomenon, and D4 and R6 form a quick discharging circuit, prevents from starting for the second time without starting successfully for the first time
Time shortens phenomenon.
Generator neutral point N-terminal or generator W control source of breaking carry out rectification and voltage is isolated through D3, by R4 current limlitings to
C2 charges, and when 6 pin voltages are charged to more than 1 pin and 7 pin voltage, Q1 cut-off conductings, starter relay disconnects, and reaches protection and starts
The purpose of machine.R7 and D5 forms the quick discharging circuit of a generator neutral point, prevents after stopping working, calls a taxi and carries again at once
Preceding protection disconnects phenomenon.R8 current-limiting resistances, D6 are LED light emitting diodes, detect generator neutral point working condition at any time, convenient
Observation and maintenance, at work, there is high voltage input at generator neutral point N or W ends to engine, then Q1 just ends and led when calling a taxi
It is logical, starter relay will not adhesive, be not in restarting phenomenon, can prevent engine it is counter drag motivation and caused by burn
Starter phenomenon, reach the purpose of protection starter.This protection and protection above do not conflict, as long as there is protection all the way dynamic
Make, Q1 just ends conducting, and starter relay disconnects, and reaches the purpose of duplicate protection starter.
The defencive function sections in series of duplicate protection module of the present invention is among the coil of starter relay, with control
The break-make of coil earth terminal processed realizes defencive function.The feeder ear of duplicate protection module and the starting end of starter relay coil
It is connected, for being powered to protection module.The signal end of duplicate protection module picks up interior generator neutral point, whether to detect vehicle
Normal starting or it has been currently running.The earth terminal of duplicate protection module is grounded by starter relay metal shell.
During starting, supplied simultaneously to the terminals of duplicate protection module second and relay coil one end simultaneously by ignition switch
Electricity, vehicle unstart that and if only if complete before, the terminals of duplicate protection module second and the 3rd terminals in an ON state,
The moment indirect earthed start-up operation of the relay coil other end, and the state maintains 10 seconds or so the second terminals to be connect with the 3rd
Line end disconnects, and relay coil is stopped, and protects the starter will not to be burnt out because long-time is powered with this, this is the first weight
Protection.
Under normal circumstances, 3 seconds or so the seconds of vehicle can complete to start, and when normal working of engine, can drive generator
Into generating state, now high potential occurs in generator neutral point, connected by wire the high potential signal is passed to it is dual
Protection module lug plate, now the terminals of duplicate protection module second and the 3rd terminals can be delayed 2 seconds or so after receiving signal
Off-state is constantly in, until the blackout.It is starter vehicle is just delayed after the completion of being started in 10 seconds 2 seconds or so
Power-off, to ensure vehicle in engine operation process, driver and conductor touches ignition switch by mistake will not also make starter work, can
Effectively prevent engine is counter from holding up motivation, this is protected again for second.
The present invention duplicate protection module insulated, fixed by 906 casting glues, radiated, waterproof, sealing, prevent protection module
Make moist, intake, shaking, temperature is too high and causes failure.
Starter relay adds after duplicate protection module the benefit brought：（1）Add the starting relay of duplicate protection module
Device, starting time are controlled at 10 seconds or so by protection module, can disconnect starter relay automatically more than 10 seconds, avoid the starting time
It is long to burn out starter；（2）The starter relay of duplicate protection module is added, another protection is that engine operation prevents two
Secondary start protection, vehicle drives engine to operate in mobile process, by starter, while driven by engine generator is sent out
Electricity, when rotating speed reaches 500 turns after engine starts successfully, when generator neutral point voltage reaches 12V or so, protection module is prolonged
When 2 seconds it is automatic disconnect starter relay, engine can be ensured in operation, starter will not work, and prevent engine from transporting
Occur reignition phenomenon in row, can effectively avoid engine is counter from holding up motivation, so as to reduce the damage of starter and burning
Ruin.
