Abstract
The utility model relates to an automatic device for exchanging automotive headlamps, which is composed of a housing and a built-in circuit. A circuit portion is divided into an induction portion, a control portion, and an exchanging portion; the induction portion is composed of a high-precision cadmium sulphide photoconductive resistor Rs; the control portion is composed of an NPN type transistor Q and a resistor R, and the exchanging portion is composed of a relay K. The utility model has the advantages of simple structure, convenient operation, and safe performance. When meeting distance of both automobiles is 150 meters, the automobile which is provided with the automatic device for exchanging automotive headlamps can automatically make a far-light lamp converted to a near-light lamp, and occurrence of traffic accidents can be reduced.
Description
The utility model relates to a kind of automobile long-and-short distant light automatic clearing apparatus.
Press traffic regulation, vehicle dark day, night, two cars were at a distance of 150 meters the time when travelling, both sides' front lamp of vehicle must become passing light, so that improve both sides driver's the lightness of looking, the driver is not produced dazzle the eyes, and prevents or the generation of minimizing accident.But there be limited evidence currently of has the driver to operate by chapter for various reasons, and traffic accident happens occasionally.
The purpose of this utility model is to provide a kind of and meets when 150 meters left and right sides at two cars, and two cars can both be sensed the brightness of the other side's headlight automatically, automatically country beam is converted to the automobile long-and-short distant light automatic clearing apparatus of passing light.
The utility model purpose is achieved through the following technical solutions: it is to be made of shell and circuit part, circuit part is divided into the sensing part, control part and switching part, the sensing part is made up of a high precision photoconductive cell, control part is made up of NPN type aerotron and resistance, switching part is made of relay, the sensing part is contained in separately in the housing, control part and switching part place in another housing, connect by lead between two housings, its physical circuit is: photoconductive cell one is terminated at the car direct current power supply of 12V, the other end connects transistor base and resistance one end, resistance other end ground connection in parallel with transistor emitter, the collecting electrode of aerotron is connected to an end of relay working coil, the other end of relay working coil connects the 12V car direct current power supply, and the moving of relay connects on the control line of automobile dipped headlight the other end ground connection of lamp in succession, the relay break is received on the control line of country beam, the other end ground connection of lamp.
The utlity model has characteristics simple in structure, easy to use, safe and reliable.Meet at a distance of 150 meters the time at two cars when the vehicle that the utility model device is housed, two cars all can be sensed the brightness of the other side's light automatically, and the light with oneself converts passing light to by country beam automatically, has been then not changing of passing light.When the end of meeting of two cars, inductor can detect the brightness of the place ahead light at once, luminance shortage then at once the dimming lamp be country beam.This change procedure is finished in the short time with the utmost point of millisecond meter at number.Make the driver not need the manual regulation long-and-short distant light, need not take sb's mind off sth, need not consider the safety problem of car light, can significantly reduce the generation of traffic accident.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of structural representation of the utility model device.
Fig. 2 is the utility model manipulated or operated apparatus.
As shown in drawings, circuit part of the present utility model is divided into sensing part, control part and switching part, the sensing part is made up of a high precision cadmium sulphide photoconductive cell Rs, and control part is made up of a NPN type aerotron Q and resistance R, and switching part is made up of a relay K.Photoconductive cell Rs one is terminated on the car direct current power supply of 12V, the other end connects the base stage of aerotron Q and an end of resistance R, the resistance R other end and aerotron Q emitter ground connection in parallel, the collecting electrode of aerotron Q is connected to an end of relay K working coil, the other end of relay K working coil connects the 12V car direct current power supply, and the contact heel a of relay K connects on the control line of automobile dipped headlight, the other end ground connection of lamp, relay K break b connects on the control line of country beam, the other end ground connection of lamp.The photoconductive cell Rs of inductor places separately in the rectangular enclosure, constitute inductor 1 as shown in Figure 1, control part and switching part are placed in the shell of a convex shape, constitute control exchanger 2 as shown in Figure 1, in the shell of control exchanger 2, the working coil of relay K is positioned in the projection, and the contact heel a of relay K and break b are positioned over the working coil below, and aerotron Q and resistance R are positioned over the lower right corner in the shell.Connect by lead between inductor 1 and the control exchanger 2.
The inductor 1 of this device is loaded on the indoor Windshield of vehicle drive, with driver's sight line peer-level.For different vehicles, the receiving angle difference of inductor is the best to keep the inductor receiving surface vertical with beam direction.The control exchanger is loaded on the place, locus of bearing circle front lower place in the operator's compartment, does not influence any operating function of driver.
The shell of the utility model device can be designed to different shape as required.
