Abstract
The utility model relates to an automatic dimming controller for motor vehicles, which is convenient in operation and benefits safe running, and besides, the utility model can prevent barbaric running and reduce the fatigue degree of drivers. The utility model is provided with a switching control circuit and a power circuit, wherein, the input end of the switching control circuit is provided with an amplifier, a current-limiting resistor and a photoresistor are arranged between the output end of the power circuit and a system ground wire, and nodes of the power circuit are connected with the input end of the amplifier.
Description
The utility model relates to a kind of self-propelled vehicle automatic beam change controller.
Self-propelled vehicle should be closed headlight when meeting, open passing lamp, and this is basic traffic general knowledge.But during owing on the way travel, the frequent intersection of self-propelled vehicle, if by the traffic regulation requirement, thing must cause the frequent transitions of passing lamp, head lamp switch, it is pretty troublesome to operate.In the middle of reality, quite a few driver is reluctant to close headlight when meeting, and takes to slow down the way of the speed of a motor vehicle.Because the place ahead road conditions are unclear, cause the generation of traffic accident often.
The purpose of this utility model be to provide a kind of easy and simple to handle, help traffic safety, can prevent barbarous driving, reduce the self-propelled vehicle automatic beam change controller of tired driver degree.
The utility model is achieved in that it has an ON-OFF control circuit and power circuit, its special character is, input end at ON-OFF control circuit is connected to amplifier, be serially connected with current-limiting resistance and photoconductive cell between the mouth of power circuit and system's ground wire, its node links to each other with amplifier input terminal.
According to above-mentioned self-propelled vehicle automatic beam change controller, be connected to the potential device that is used to adjust sensitivity at the current-limiting resistance and the photoconductive cell two ends of serial connection, the adjustment end of said potential device links to each other with another input end of amplifier.
The utility model has the advantages that: 1, simple in structure, easy to use, highly sensitive, cost is low; 2, when meeting, can guarantee traffic safety at the remote automatic beam change of realizing; 3, do not close the generation of headlight situation in the time of can preventing cruelty driving one meeting; Can reduce the tired driver degree again, guarantee that the driver is free and relaxed when driving a vehicle night; 5, can save the energy, timely automatic beam change in the Vehicle during Crossing Event has been avoided the too much reduction speed of a motor vehicle, and open the throttle wide travels and makes the appearance of the situation that oil consumption increases again; 6, widely applicable, applicable to 6V motor bike, 12V automobile and 24V diesel-powered vehicle.
The drawing explanation:
Fig. 1 is schematic circuit diagram of the present utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in the figure, the utility model has a power circuit 4 and by resistance R
2, relay J and protection diode D
1, switch transistor T
1And capacitor C
1The ON-OFF control circuit 5 that constitutes is connected to op amp 3 (model is LM393, and pin 1.～8.) at the input end of ON-OFF control circuit 5, is serially connected with current-limiting resistance R between the mouth of power circuit 4 and system's ground wire
1With photoconductive cell 1, said current-limiting resistance R
12. link to each other with the input end of op amp 3 with the node 2 of photoconductive cell 1, at the current-limiting resistance R of serial connection
1Be parallel with potential device W with photoconductive cell 1 two ends
1, said potential device W
1The adjustment end 3. link to each other with another input end of op amp 3, be used to adjust the sensitivity of received signal.
When mounted, photoconductive cell 1 is contained in the front end of self-propelled vehicle, the normally closed contact J1 of the relay J in the ON-OFF control circuit 5 is serially connected in the headlight loop.In self-propelled vehicle cruising way, with the relative self-propelled vehicle that travels during to setpoint distance, photoconductive cell 1 is connected the loop, make op amp 3 input ends 2. be active potential, the mouth of op amp 3 is a high potential, connects ON-OFF control circuit 5, the relay J adhesive, its normally closed contact J1 disconnects, the switching off the headlamp loop, and headlight goes out.When the self-propelled vehicle that travels relatively crossed, photoconductive cell 1 was turn-offed again, and 1. the mouth of op amp 3 becomes active potential again, and ON-OFF control circuit 5 repeat circuit J discharge, and its normally closed contact J1 resets, and connected headlight, thereby finished headlight automatic beam change control process.
Claims (2)
1, a kind of self-propelled vehicle automatic beam change controller, comprise ON-OFF control circuit and power circuit, it is characterized in that, input end at ON-OFF control circuit is connected to amplifier, be serially connected with current-limiting resistance and photoconductive cell between the mouth of power circuit and system's ground wire, its node links to each other with amplifier input terminal.
2, self-propelled vehicle automatic beam change controller according to claim 1 is characterized in that, is connected to the potential device that is used to adjust sensitivity at the current-limiting resistance and the photoconductive cell two ends of serial connection, and the adjustment end of said potential device links to each other with another input end of amplifier.
