Abstract
The invention discloses a control protector of an automobile starter, comprising a single chip microcomputer; the signal input end of the single chip microcomputer is electrically connected with the signal output end of a voltage detection module; the input end of a voltage detection module is electrically connected with the voltage output end of a vehicular power generator; the output end of the single chip microcomputer is electrically connected with the input end of a relay control module, the output end of the relay control module is electrically connected with one end of a coil of a protecting relay, and the other end of the coil of the protecting relay is grounded; and a normally-closed contact of the protecting relay is connected in a coil circuit of a start relay of an ignition lock of the automobile starter in series. The control protector has the advantages that when the ignition lock is started, the starter drives an engine to rotate, and the power generator is driven to rotate to generate power by the engine; and when the voltage of the power generator reaches 12V, the voltage detection circuit detects that the voltage leads the coil of the start relay to be powered-on and disconnect the automobile starter and a vehicular direct-current power supply. The occurrence of the phenomenon that the starter is damaged due to faults of the ignition lock is avoided, and the safety and the reliability of starting an automobile are guaranteed.
Description
Technical field
The present invention relates to automobile starter, especially relate to automobile starter control protection module.
Background technology
Along with the develop rapidly of auto-domain, more and more higher to the reliability requirement of each parts of automobile, device.During automobile starting igniting at present, be to switch on to starter motor, thereby drive the driving engine operation by ignition lock; When engine running just often, the automatic resilience of ignition lock disconnects starter motor and vehicle-mounted direct supply.But, if after the ignition lock resilience or ignition lock break down can not resilience because driving engine this moment normal operation, and starter motor still is electrically connected with vehicle-mounted direct supply, this will cause the starter motor damage or burn.
Summary of the invention
The object of the invention is to provide a kind of safe and reliable automobile starter control protector.
For achieving the above object, the present invention can take following technical proposals:
Automobile starter control protector of the present invention, it comprises micro controller system, described micro controller system signal input part is electrically connected with the voltage detection module signal output part; Described voltage detection module input end is electrically connected with the mobile generator voltage output end; The micro controller system mouth is electrically connected with the relay control module input end, and described relay control module mouth is electrically connected with coil one end of protective relay, the coil other end ground connection of protective relay; The normally closed contact of protective relay is series in the ignition lock starting relay coil circuit of automobile starter.
Described relay control module is made of aerotron; Described transistor collector is electrically connected with Vehicular accumulator cell, and its base stage is electrically connected with described micro controller system mouth by resistance, and its emitter is electrically connected with coil one end of described protective relay.
The invention has the advantages that when ignition lock starts, starter motor drives engine rotation, drive the electrical generator rotary electrification by driving engine, when generator voltage reaches 1 volt (voltage when on-board engine begins normal operation), described voltage detecting circuit promptly detects this available voltage and makes described relay control module work by described micro controller system, described starting relay coil gets, this moment, its normally closed contact J1 that is series in the starting relay coil circuit of automobile starter disconnected, ignition lock starting relay dead electricity disconnects its open contact J2, and automobile starter and vehicle-mounted direct supply disconnect.Stopped because of after the ignition lock resilience or ignition lock break down and can not resilience cause starter motor to damage the generation of phenomenon, guaranteed the safety and the reliability of automobile starting.Circuit layout of the present invention is simple, compact, cheap for manufacturing cost simultaneously.
