The AC generator for vehicle that the utility model proposes and AC generator for vehicle failure detector circuit when not changing generator original structure, do not affect generator when normally using, a simple indicator light circuit is connected between storage battery positive terminal with charging indicator light connection terminal, car load circuit can be got around by the luminous situation of LED light, whether independent judgment generator itself breaks down, and efficiently solves the erroneous judgement to generator when charging system breaks down.
Accompanying drawing explanation
The AC generator for vehicle one-piece construction schematic diagram that Fig. 1 provides for the utility model embodiment one;
The indicator light circuit structural representation that Fig. 2 provides for the utility model embodiment one;
The AC generator for vehicle failure detector circuit application circuit that Fig. 3 provides for the utility model embodiment two.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Be understandable that, specific embodiment described herein only for explaining the utility model, but not to restriction of the present utility model.It also should be noted that, for convenience of description, illustrate only the part relevant to the utility model in accompanying drawing but not full content.
Embodiment one
Please refer to shown in Fig. 1, in the present embodiment, AC generator for vehicle 101 is provided with terminal block 102, described terminal block 102 is provided with storage battery positive terminal B+, charging indicator light connection terminal D+, speed feedback connection terminal W and neutral connection terminal (in Fig. 1 symbolically), described storage battery positive terminal B+ is connected an indicator light circuit with between charging indicator light connection terminal D+.
As shown in Figure 2, described indicator light circuit comprises diode D1, LED light D2 and resistance R1, described diode D1 and LED light D2 after connecing, and one end connects charging indicator light connection terminal D+, one end of other end contact resistance R1, the other end of resistance R1 connects storage battery positive terminal B+.Terminal block 101 described in the present embodiment offers a through hole 103, described LED light D2 is arranged in through hole 103.
AC generator for vehicle 101 operationally, when storage battery is opened, generator speed reach build pressure rotating speed before, owing to there is voltage difference between storage battery positive terminal B+ and charging indicator light D+ connection terminal, so LED light D2 lights, generator speed reach build pressure rotating speed normally work time, there is not voltage difference between storage battery positive terminal B+ and charging indicator light connection terminal D+, LED light D2 extinguish.Therefore, if generator speed reach build pressure rotating speed normally work time, LED light D2 lights and maybe can not extinguish, then illustrate still there is voltage difference between storage battery positive terminal B+ and charging indicator light connection terminal D+, judges that generator exists fault.
Embodiment two
As shown in Figure 3, the AC generator for vehicle failure detector circuit application circuit that provides for the utility model embodiment two of Fig. 3.In figure, 301 is generator unit stator winding, 302 is rectifier circuit, 303 is voltage modulator circuit, 304 is AC generator for vehicle failure detector circuit, be called for short failure detector circuit, B+ is storage battery positive terminal, and D+ is charging indicator light connection terminal, W is speed feedback connection terminal, and earth terminal is neutral connection terminal.It should be noted that, generator unit stator winding 301, rectifier circuit 302, voltage modulator circuit 303, and the circuit structure of failure detector circuit 304 is only for ease of understanding the simple signal of the utility model principle, is not limited thereto in practical application.
In the present embodiment, AC generator for vehicle failure detector circuit 304 comprises indicator light circuit.One end of described indicator light circuit connects the storage battery positive terminal B+ of AC generator for vehicle, the charging indicator light connection terminal D+ of the other end and AC generator for vehicle.With embodiment one, described indicator light circuit 304 comprises diode D1, LED light D2 and resistance R1; Described diode D1 and LED light D2 after connecing, one end connects charging indicator light connection terminal D+, one end of other end contact resistance R1, and the other end of resistance R1 connects storage battery positive terminal B+.
When storage battery is opened, before generator speed reaches and builds pressure rotating speed, owing to there is voltage difference between storage battery positive terminal B+ and charging indicator light connection terminal D+, electric current will be had in failure detector circuit 304 flow into, so LED light D2 can light, therefore, judge whether AC generator for vehicle exists fault, mainly check generator speed reach build pressure rotating speed normally work time, the lighting conditions of LED light D2.Generator speed reach build pressure rotating speed normally work time, if there is not fault in generator, then the voltage at storage battery positive terminal B+ and charging indicator light connection terminal D+ two ends is equal, electric current will not be had in failure detector circuit 304 flow into, the LED light D2 that early stage lights will extinguish, therefore, if now LED light D2 continues to light and maybe can not extinguish, then illustrate that the voltage at storage battery positive terminal B+ and charging indicator light connection terminal D+ two ends is unequal, namely there is voltage difference, then judge that generator exists fault
The technical solution of the utility model when not changing generator original structure, do not affect generator when normally using, a simple indicator light circuit is connected between storage battery positive terminal with charging indicator light connection terminal, car load circuit can be got around by the luminous situation of LED light, whether independent judgment generator itself breaks down, and efficiently solves the erroneous judgement to generator when charging system breaks down.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, to those skilled in the art, the utility model can have various change and change.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
