Description
Technical field
The invention belongs to automobile and application of electronic technology field, it is related to a kind of electric automobile horn and gradually rings controller.
Background technology
The common typical operating mode of electric automobile horn is that electric horn is coupled with whole voltages in moment when in use, electricity
The pedestrian that loudspeaker send out especially ear-piercing sound, especially road at once is highly susceptible to frighten in the case of no attention.
One kind can be designed when connecting electric automobile horn power supply, electric horn, which changes from small to big, gradually sends out the sound, is closing electric loudspeaker

Electric automobile horn of the present invention gradually ring controller circuitry in core element select be time base circuit, it use
Be pulse width modulation circuit, the loudness that its adjustable electric horn makes a sound.
Electric automobile horn of the present invention described further below gradually ring controller in implementation process it is involved it is necessary,
Key technique content.
Invention content
Goal of the invention and advantageous effect：Common electric automobile horn typical mode of operation is that electric horn is in moment when in use
Whole voltages are coupled with, electric horn sends out the pedestrian of especially ear-piercing sound, especially road the case where not paying attention at once
Under be highly susceptible to frighten.For the present invention when connecting electric automobile horn power supply, electric horn, which changes from small to big, gradually sends out the sound,
When closing electric horn power supply, the electric horn sound is gradually to become smaller, and electric horn takes such operating mode more to become hommization.
Circuit operation principle：Electric automobile horn of the present invention gradually rings controller, it is connected into duty by time base circuit IC1
Than adjustable squarer, pulse frequency about 80Hz, duty ratio size is adjusted by linear potentiometer RP.Capacitance C1 chargings
Time mainly determines by the time constant of resistance R1, the top half of linear potentiometer RP and resistance R2 and capacitance C1, when electric discharge
Between then determined by the time constant of the lower half portion of linear potentiometer RP, resistance R2 and capacitance C1.During capacitance C1 is electrically charged,
Because the 2nd foot of time base circuit IC1 is in low level, time base circuit IC1 is in set.It is exported in the 3rd foot of time base circuit IC1 high
During level, shone by enhanced N-channel field-effect tube VT1 driving electric horn LB sounding and highlighted white Light-emitting diode LED.
In capacitance C1 discharge times, time base circuit IC1 is in reset state, and the 3rd foot of time base circuit IC1 exports low electricity
Usually, enhanced N-channel field-effect tube VT1 cut-off, electric horn LB and highlighted white Light-emitting diode LED no current by without
Work.
When linear potentiometer RP sliding ends are located at previous position, the capacitance C1 charging time shortens, and discharge time lengthens, institute
Smaller, the electric horn LB with the average current by electric horn LB and highlighted white Light-emitting diode LED in pulse a cycle
It makes a sound with regard to small, highlighted white Light-emitting diode LED light emission luminance with regard to dark.When linear potentiometer RP sliding ends move down
When, the capacitance C1 charging time is elongated, and discharge time reduces, and above-mentioned working condition is just opposite in pulse a cycle.So
Linear adjustment potentiometer RP can change the loudness of electric horn LB sounding and change highlighted white Light-emitting diode LED shine it is bright
Degree.
The principle that electric horn is gradually rung is exactly between the 3rd foot output high period of time base circuit IC1, because in enhanced N ditches
1 electrolytic capacitor C2 of adjunction in the grid circuit of road field-effect tube VT1 makes electric horn LB need to be electrolysed electricity obtaining full voltage
Hold C2 and gradually complete charging process, so the sound of electric horn LB is also gradually ascending, but electric horn gradually rings this process
Time is very short, can be completed in moment.
