Shown in accompanying drawing 4-1, resistance (R5) in the amplifying circuit (II) and resistance (R32) can make the 1st pin of op amp (N1) and the 2nd pin keep zero level, increase stability, prevent to disturb.Be 2 seconds the drop away time of resistance (R27), electric capacity (C5) in the unglazed comparator circuit (IX), do not produce the light that dangles when guaranteeing continuous meeting, also increases stability.
Shown in accompanying drawing 4-2, the voltage ratio at coil two ends is higher during relay (K1) action, and about 24V to 28V, it is then lower to keep voltage, and about 18V, this has just solved the heat-producing problem of relay coil preferably, has increased the power of Dim Dimmer.
Briefly narrate principle of work of the present invention below.
Meeting becomes the light guide principle of work: when two cars during at a distance of 250 meters, photo-transistor (E1) receives the distance light optical signal of the other side's vehicle and produces photocurrent, make op amp (N1) the 3rd pin obtain an electric signal, the 1st pin is given a road of electric signal on the 2nd pin of op amp (N2), this signal is lower than the level of the 3rd pin, makes the 1st pin low level, and digital integrated circuit (D1) the 6th pin is low level also, the 4th pin high level, the 2nd pin is high level also.Op amp (N1) the 1st pin is given the 12nd pin of op amp (N2) with another road of electric signal, and this signal is higher than the 13rd pin level, makes the 14th pin high level, and digital integrated circuit (D1) the 1st pin is high level also.Like this, digital integrated circuit (D1) the 3rd pin low level, the 10th pin high level, the 12nd pin is high level also.The photocurrent of photo-transistor (E1) makes op amp (N1) the 5th pin obtain an electric signal simultaneously, the 7th pin high level, op amp (N2) the 6th pin is high level also, and is lower than the 5th pin level, make the 7th pin high level, digital integrated circuit (D1) the 13rd pin is high level also.Like this, digital integrated circuit (D1) the 11st pin low level, op amp (N2) the 9th pin is low level also, the 8th pin high level, aerotron (V14) conducting, digital integrated circuit (D2) the 5th pin low level, aerotron (V15) ends, the 8V power supply is by resistance (R64, R65) to electric capacity (C15) charging, make digital integrated circuit (D3) the 3rd pin low level, aerotron (V18) ends, the 8V power supply is by resistance (R69, R72) and diode (V29), make aerotron (V21) conducting, aerotron (V22) ends, relay (K1) discharges, and head light is in the dipped beam state.If the other side's vehicle is used distance light always, op amp (N2) the 6th pin level is higher than the 5th pin level, the 7th pin low level, digital integrated circuit (D1) the 11st pin high level, op amp (N2) the 9th pin high level, and be higher than the 10th pin, the 8th pin low level, diode (V7) ends, and aerotron (V14) also ends, last relay (K1) adhesive, head light is in high-beam condition.Under the situation that vehicle front is unglazed, op amp (N1) the 1st pin low level, op amp (N2) the 12nd pin low level, and be lower than the 13rd pin, the 14th pin low level, digital integrated circuit (D1) the 3rd pin high level, the 10th pin low level, the 11st pin high level, relay (K1) adhesive as a result, head light is in high-beam condition.
Turn to and become the light guide principle of work: press left steering switch (S3-1), diode (V8, V13), resistance (R52, R53, R55) and electric capacity (C8) make aerotron (V14) conducting, relay (K1) release, head light is in the dipped beam state.Press right steering switch (S3-2) too.
Overtake other vehicles and become the light guide principle of work: press the switch of overtaking other vehicles (S4), when Der Blink und Abblendschalter output high level, by resistance (R59), one the tunnel charges to electric capacity (C12) through diode (V10), make op amp (N2) the 9th pin high level by resistance (R61) and diode (V6) again, the 8th pin low level, diode (V7) ends.Another road ends diode (V13) through diode (V11), aerotron (V14) conducting, and relay (K1) discharges, and head light is in the dipped beam state.When the Der Blink und Abblendschalter output low level, aerotron (V14) ends, relay (K1) adhesive, and head light is in high-beam condition.Along with the height variation of Der Blink und Abblendschalter outgoing level, head light distance light, dipped beam alternate.
Meeting, turn to and the three kinds of mode of operations of overtaking other vehicles in, the override of overtaking other vehicles.After the switch (S4) of promptly overtaking other vehicles pressed down, meeting became light and turns to change light not work.Turn to be better than meeting, after promptly pole changer (S3) pressed down, meeting became light and does not work.
Obviously, the present invention turns to and also can automatic beam change when overtaking other vehicles except having nighttime meeting head light automatic beam change function, and obstacle overcome ability is stronger, is beneficial to safe driving, alleviates tired driver, can be widely used in all kinds of self-propelled vehiclees.
