In the utility model, when two vehicles meet or a vehicle follows another vehicle, a conversion from high beam light to low beam light is automatically accomplished; and the automatic adjusting device for the headlight is simple in structure, low in cost and is adaptive to most of vehicles.

Description

The headlight self-checking device

Technical field

The utility model relates to a kind of self-checking device, especially a kind of headlight self-checking device.

Background technology

Automotive lamp is the various traffic lights that are installed in order to guarantee safe driving on the automobile, divides illuminating lamp and signal lamp two classes.Illuminating lamp is called head lamp again, and the main application of head lamp is road and the object before the flood lighting vehicle, guarantees traffic safety.Can also utilize distance light, dipped beam alternately to change irregularly as the signal of overtaking other vehicles night.Head lamp is installed in the both sides of automobile head, and each car is adorned two or many.

For head lamp, distance light and dipped beam have been adopted.Distance light is not have the remote illuminating bundle of sending a car or using when not trailing other automobiles forwardly.Dipped beam is at the intersection car or the closely illuminating bundle that uses when trailing other automobiles.

At the intersection car or when trailing other automobiles, normally manually convert distance light to dipped beam, be convenient to driving safety.Owing to be manual switch, when forgetting that conversion or conversion are not rapid, be easy to take place traffic accident.

The utility model content

In order to prevent the dazzling traffic accident that causes of light, the purpose of this utility model is to provide a kind of headlight self-checking device, controls by infrared facility, and at the intersection car or when trailing other automobiles, distance light converts dipped beam automatically to.

In order to realize that the technical scheme that the purpose of this utility model adopts is: a kind of headlight self-checking device is characterized in that: it is made of projector 1, lamp bracket 2, short range lamp 3, remote lamp 4, receptor 5, treater, sensor circuit, control circuit and lighting circuit; Described projector 1 is an infrared transmitting device, and receptor 5 is the receiving infrared-ray device, and treater is the device of processing, control information; The size of described remote lamp 4 is twice than short range lamp 3, and two short range lamps 3 are located at the right and left of remote lamp 4, and is installed in the lamp bracket 2; Described sensor circuit is made up of infrared light-emitting diode VL, the photosensitive transistor V1 of infrared ray, transistor V2, resistance R 1, R2 and potential device RP; Described control circuit is made up of chip IC, relay J, capacitor C, resistance R 3; Lighting circuit is made up of K switch 1, K2 and short range illuminator L1 and long-range illuminator L2.

The beneficial effects of the utility model are: in the two cars intersection or when trailing other car, finish the conversion of distance light and dipped beam automatically; Simple in structure, cost is lower, and is practical, is applicable to most of automobiles.

1-projector, 2-lamp bracket, 3-short range lamp, 4-remote lamp, 5-receptor among the figure.

The specific embodiment

In Fig. 1, Fig. 2, first embodiment shown in Figure 3, a kind of headlight self-checking device is characterized in that: it is made of projector 1, lamp bracket 2, short range lamp 3, remote lamp 4, receptor 5, treater, sensor circuit, control circuit and lighting circuit; Described projector 1 is an infrared transmitting device, and receptor 5 is the receiving infrared-ray device, and treater is the device of processing, control information; The size of described remote lamp 4 is twice than short range lamp 3, and two short range lamps 3 are located at the right and left of remote lamp 4, and is installed in the lamp bracket 2; Described sensor circuit is made up of infrared light-emitting diode VL, the photosensitive transistor V1 of infrared ray, transistor V2, resistance R 1, R2 and potential device RP; Described control circuit is made up of chip IC, relay J, capacitor C, resistance R 3; Lighting circuit is made up of K switch 1, K2, short range illuminator L1 and long-range illuminator L2.

In second embodiment shown in Figure 3, when two cars was trailed in not having intersection or certain limit, V1 did not receive the infrared ray of VL emission, and V2 remains static, and IC does not work, and J voltage is low, and K2 is a closure state, and distance light is sent in the L2 energising; When trailing in two cars intersection or the certain limit, opposite or fwd car light produce stronger scattering process to the infrared ray that VL sends, the infrared ray of scattering is received by V1, the working current of V1 is increased, the saturated energising of V2, IC is triggered and is worked, IC with the electric signal of output after J amplifies, adhesive K1, dipped beam is sent in the L1 energising.

In Fig. 1, the 3rd embodiment shown in Figure 2, when trailing other car in not having intersection car or certain limit, remote lamp 4 is luminous; When trailing other car in two car intersections or certain limit, projector 1 sends stronger infrared ray, and receptor 5 receives the infrared ray that projector 1 sends, and with this information transfer to treater, after the processor processing and control remote lamp 4 and go out, short range lamp 3 is bright.
