Description
The invention belongs to the car electrics accessory, it is applicable to the electronic controller of the alternating current generator that automobile, tractor and fixed internal combustion engine are used
Along with the continuous development of automotive engineering, automobile current generator carries out the transition to alternating current generator from DC generator.Therefore the dynamo governor that is used with it also develops into bigeminy, simply connected electromagnetic vibrating type regulator from original direct current three electromagnetic vibrating type regulators, along with the maturation of electronic technology and the raising of reliability of electronic components, electronic controller has begun to be applied on the automobile current generator in recent years, and since it have regulate highly sensitive, contactless, advantages such as good reliability more demonstrate huge vitality.Data according to Changsha Automobile Electric Appliance Research Inst. and Nanjing Vehicle Research Inst., and the retrieval of domestic automobile electrical equipment magazines such as " car electrics ", " automobile and accessory " all used the Electromagnetically vibrating relay as having the generator that charging indicator light shows on the automobile, the electronic controller of employing and the discrete installation of charge indicator relay are arranged at present, the Electromagnetically vibrating alternator regulator that adopts relay with charging indicator light is also arranged.
At present, the Electromagnetically vibrating relay that the automobile current generator system adopts is as the vehicle charging indicating light relay, and with the electronic controller packing, or attach together with electromagnetic vibrating type regulator.Overall dimensions are big, and degree of regulation is low, and because the contact is arranged, so the life-span is short, shock resistance, poor reliability.
The objective of the invention is precision and the reliability that adopts electronic technology to improve adjuster and prolong working life and reduced volume.
Solution of the present invention is to utilize electronic switching circuit to form the electronic controller of relay with charging indicator light, it controls the turn-off time of dynamo field coil by the sampling of output voltage, reaching the purpose of regulator generator voltage, and control the demonstration of charging indicator light by neutral voltage.
Principle of the present invention and theing contents are as follows: after shown in figure one, connecting the igniting K switch, alternating current generator 2 under the low situation of rotating speed,
Point voltage will be lower than voltage stabilizing didoe DW
1, DW
2Reverse breakdown voltage, DW
1, DW
2Not conducting, triode BG
1Because of there not being base current to end, the voltage of storage battery 3 passes through resistance R
5Be added in triode BG
2Base stage on, this moment triode BG
2, BG
3Conducting.The electric current of storage battery 3 is by triode BG
3Collector electrode is to BG
3The magnet exciting coil that emitter arrives generator 2 again arrives ground wire E then, and this moment, magnet exciting coil had electric current to pass through, and alternating current generator 2 sends voltage, and the neutral point sampling voltage
Owing to do not reach BG as yet
4Base voltage, BG
4End BG
5Conducting, battery positive voltage → charging indicator light L at this moment
1→ BG
5Collector electrode → BG
5Emitter → E forms the loop, makes charging indicator light shinny.
Along with the rising of alternator output voltage, neutral point voltage also and then raises, and charging indicator light extinguishes when reaching certain value, and its sampling voltage is higher than DW respectively
1, DW
2Reverse breakdown voltage and BG
4Base voltage the time, DW
1, DW
2Respectively conducting makes BG
2BG
3And BG
5End, this moment, magnet exciting coil and charging indicator light electric current were cut off respectively, thereby made magnet exciting coil not have electric current, and charging indicator light extinguishes, and this moment, output voltage and neutral voltage and then descended.
When output voltage and neutral voltage drop to certain certain value, promptly
When point voltage is lower than certain certain value respectively, BG
1, BG
4End BG
2, BG
3, BG
5Conducting, this moment magnet exciting coil by electric current, charging indicator light is shinny, thus generator boosted voltage again so, carries out repeatedly, makes alternator voltage, the charging indication is stabilized in the scope of its technical conditions regulation.
The present invention compared with prior art have volume little (for the electric and magnetic oscillation co-volume 1/4) high temperature performance is stable, precision height, long, good reliability of life-span, advantage such as shockproof, dustproof, moisture resistance is the 14V electric system technical indicator table of comparisons 1 below:
