Abstract

The utility model which discloses an automatically switching controller of a front headlight when the vehicle automatically crosses at night comprises main control elements, such as a photodiode, an integrated circuit, a direct current relay. When the vehicle is moving at the night and enters into the crossing section, the front headlight can automatically switch the far-light state to a near-light state, meanwhile the buzzer can produce sounds to warn the driver that the vehicle is in the cross section, and the driver must drive carefully. When the crossing is over, the near-light state of the front headlight of the vehicle can be automatically switched to the far-light state of the normal driving at night, and the buzzer can stop to produce sounds.

Description

Cars meeting at night head light automatic switchover controller

Head light brightness automatic switchover controller when the utility model relates to a kind of cars meeting at night, the automatic switchover of head light instant and near light lamp when being used for cars meeting at night.

Present all automobiles, all be to pull or pin is stepped on beam deflector switch and operated head light distance light and dipped beam state when the night running meeting with hand, the chaufeur range estimation is sailed next automobile when 150 meters left and right sides during practical operation, chaufeur is pulled or pin is stepped on beam deflector switch head light is switched to the dipped beam state from high-beam condition, this M/C has increased the fatigue of chaufeur night travel, and estimate two cars at a distance of 150 meters full experiences of leaning on, error is bigger, all might influence night travel safety.

When task of the present utility model provides a kind of automobile night travel two cars travel relatively at a distance of 150 meters enter meeting when interval head light automatically high-beam condition is switched to the dipped beam state, buzzer phone sends the sound simultaneously, the alerting drivers automobile has entered the meeting district, drive with caution the driving of taking care.After meeting finished, head light automatically switched to high-beam condition from the dipped beam state, and head light returns to the illumination condition before the meeting.Because in the meeting interval, head light has been finished the switch operating of brightness automatically, has improved the caution sound of buzzer phone during meeting again automatically, has alleviated the labour intensity of chaufeur nighttime meeting, the safety that has improved night travel.

The utility model is achieved in that this device is made up of optical sensor, controller, optical sensor is attached to the automobile cab windshield, controller places the place of any appropriate in the operator's compartment, optical sensor is connected with the input end of controller with the lead Connector Clip, and the bulb near, far away of automobile front is connected with the mouth of controller through Connector Clip with lead.

Below in conjunction with drawings and Examples the utility model is further described.

Accompanying drawing 1 is an electrical schematic diagram of the present utility model.

Photodiode D ₂With resistance R ₂Series connection constitutes optical sensor, resistance R ₂An end ground connection, photodiode D ₂Positive pole and the integrated circuit U of controller ₁2. pin connect U ₁3. pin and aerotron Q ₁Base stage connect integrated circuit U ₁What adopt is the NE555 time-base integrated circuit, aerotron Q ₁Emitter through relay J ₁Coil ground connection, relay J ₁Moving contact be connected relay J with positive source ₁Normally closed interlock J _1-1Be connected relay J with the high beam headlight bulb of head light ₁Normally open contact J _1-2Be connected with the dimmer lamp bulb of head light, and in passing light two end parallel connections one by resistance R ₃The squealer that buzzer phone Y is in series, relay J ₁Be to adopt ZH4115 type DC relay.

Its work engineering is as follows: during automobile cruising at night, because optical sensor does not receive the wigwag of sending a car in the place ahead, and the binary pair U in the controller ₁Mouth 3. pin be in low level state, aerotron Q ₁End relay J ₁Be failure to actuate normally closed interlock J _1-1The high beam headlight bulb of automobile front is connected, and head light moves under high-beam condition, sends a car when entering 150 meters meeting districts when the place ahead, and opto-electronic pickup receives the wigwag that the automobile that comes is sailed in the place ahead, binary pair U ₁Mouth 3. pin upset be high level, aerotron Q ₁Conducting.

Relay J ₁Coil has electric current to pass through, relay adhesive, its normally closed interlock J _1-1Disconnect the high beam headlight bulb power supply of head light, country beam goes out; Relay J ₁Normally open contact J _1-2Closure is connected the head light dimmer lamp bulb, and dimmer lamp bulb has also been connected sound circuit simultaneously, buzzer phone sends the sound, photosensor does not receive the wigwag that the automobile that comes is sailed in the place ahead when meeting finishes, and binary pair IC mouth 3. pin is in low level again, transistor Q ₁End relay J ₁Coil losing electricity, head light have recovered the far lighting state before the meeting, have realized the automatic switchover of nighttime meeting head light brightness.

Claims

1, cars meeting at night head light brightness automatic switchover controller of being made up of optical sensor, auto mat, feature of the present utility model is by photodiode D ₂With resistance R ₂Be composed in series optical sensor, resistance R ₂An end ground connection, photodiode D ₂Positive pole and the integrated circuit U of controller ₁2. pin connect the 3. pin of U1 and aerotron Q ₁Base stage connect aerotron Q ₁Emitter through relay J ₁Coil ground connection, relay J ₁Moving contact be connected relay J with positive source ₁Normally closed interlock J _1-1Be connected relay J with the high beam headlight bulb of head light ₁Normally open contact J _1-2Be connected with the dimmer lamp bulb of head light, and in passing light two end parallel connections one by resistance R ₃The squealer that buzzer phone Y is in series.
