The utility model beneficial effect: this automotive headlight forgets to close voice reminder, stable performance, durable in use, low cost of manufacture, power consumption is small and volume is little, can be installed on fuel oil or the electric motor vehicle gauge panel position, remind chaufeur in time to turn off the head lamp of forgetting to close when the normal daytime driving motor-driven vehicle going of illumination by acousto-optic interaction.
Description of drawings
Accompanying drawing 1 is that the automotive headlight that the utility model provides forgets to close voice reminder circuit catenation principle figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing 1 is that the automotive headlight that the utility model provides forgets to close voice reminder circuit catenation principle figure.As shown in Figure 1, a kind of automotive headlight forgets to close voice reminder, it is characterized in that: the control termination, mu balanced circuit, integrated alarm circuit and the light-operated circuit that comprise meet sb. at the airport motor-car passing light and country beam.The control termination of described passing light and country beam comprises isolation diode VD1, diode VD2 and 6V/12V change-over swith; Described mu balanced circuit comprises resistor R 1, zener diode VD3 and cond C; Described integrated alarm circuit comprises integrated circuit block Y976, piezoelectric speaker B, LED and resistor R 2, resistor R 3; Described light-operated circuit comprises photo-transistor VT and potential device RP.The control termination is connected with the control end of country beam, passing light switch respectively.
In the accompanying drawing 1, photo-transistor VT adopts the 3DU5 model; Diode VD1 and diode VD2 adopt the 1N4001 model; Zener diode VD3 adopts the UZP-6.2B model of 6V, 1W; RP adopts the organic solid trimmer resistor of WSW type 100K Ω; R1-R3 adopts the RJ-1/4W metalster, guarantees that circuit working is reliable, resistor R 1:820 Ω, resistor R 2:68K Ω, resistor R 3:1K Ω; Electrolytic condenser C adopts the CD11 model of 47uF/25V; B adopts and mixes the piezoelectric buzzer that helps the operatic tunes, to increase phonation volume;
Principle of work: the utility model automotive headlight forgets to close voice reminder, a, b end is connected to respectively on the control termination of the passing light of motor-driven vehicle headlight adapter switch and country beam, 6V (12V) the storage battery power supply voltage that obtains when turning on light is isolated through VD1 and VD2, if the 12V storage battery also by change-over swith S through the R1 step-down, the mu balanced circuit with VD3 and C composition provides 6V stable direct current working volts for Y976 warning integrated circuit again.Close automotive headlight if forget when travel daytime, because of being subjected to the available light irradiation, photo-transistor VT presents low resistance, the dividing potential drop effect of it and potential device RP makes Enable Pin EN the 5th pin of integrated package Y976 transfer high level to, the inner starting of oscillation work of Y976, integrated circuit the 1st pin OUT end output pulse signal voltage, and driving piezoelectric speaker B sends " pouting--toot--" voice prompt of the per second four tones of standard Chinese pronunciation, the LED luminous indication of also glimmering simultaneously can be closed head lamp after automobile driver is heard the news.If night running, because of the light that shines on the VT greatly weakens, warning integrated package Y976 the 5th pin transfers low level to, and Y976 is inner locked not to work, the output of 1 pin pulse-free signal voltage, piezoelectric speaker B and LED light-emitting diode can not send Tip Sound and flash of light.RP is the light-operated threshold voltage that is used for regulating Enable Pin EN the 5th pin of integrated package Y976, makes automotive headlight forget to close voice reminder and can normally send the acousto-optic alarm by day.
Though described embodiment of the present utility model in conjunction with the accompanying drawings, the protection domain that those of ordinary skills do not need various distortion that creativity work just can make or modification still to belong to this patent within the scope of the appended claims.
