Description

Multifunction light-changing automatic controller for automobile

The utility model relates to the photoreceptor signal control setup, and especially a kind of multi-purpose vehicle(MPV) becomes light automatic controller.

Automobile is in cruising, and chaufeur also must keep and extraneous signal contact except that the driver behavior of finishing various radical functions at any time.Comprising send rational aud. snl. and various light indicating signals etc. to the external world.The vehicle of night running, situation are more complicated, except that the part light that is used for the signal indication, also are furnished with the part light that is used for night light on the car, also double as signal indication of houselights sometimes.This just makes to the operation of light and control more complicated and important.Traffic management system has been formulated very careful and strict regulation for this use to light, to guarantee the safety traffic of vehicle.However because the light of vehicle all is artificial control, and the kind of light and quantity are more again, for dividing to fall apart to a great extent, the use of light sails energy in the driving, and this operation is easy to take place traffic accident again, and there is accident potential in the moment.

The utility model purpose is: provide a kind of simple in structure, easy to operate, function is complete, and meets the multi-purpose vehicle(MPV) change light automatic controller of traffic management system regulation.

The utility model technical solution: according to the opto-electronic pickup of the forward and backward position of automobile.Forward and backward side of automobile and ground-surface light are imported correspondent control circuits as photoreceptor signal, carrying out opto-electronic conversion and signal amplifies, by Schmidt trigger, trigger the driving circuit of corresponding light at last, make the variation of the forward and backward light of automobile meet the regulation of traffic department.The basiccircuit of above-mentioned functions, its respective gut structure is:

Meeting, the single pole double throw switch of overtaking other vehicles, its moving contact P ₃Link to each other two fixed contact P with the input end of far and near light amplifirer ₁, P ₂Respectively with the mouth of far away, low beam light trigger with overtake other vehicles, the mouth of turning flash oscillator links to each other; The double pole double throw change-over swith, wherein two of a cutter fixed contacts all link to each other with an end of passing light K switch by force, and the other end of K links to each other with the input end of the fixed contact of this cutter with instant and near light lamp binary pair.

The foregoing circuit structure can realize:

1, during meeting at two cars SELF CL country beam during at a distance of 150 meters, open passing light; Automatically recover the far-reaching headlamp turn-off passing light behind the meeting.

2, during the unclear use head light of dark weather sight line,, select distance light or lower beam illumination road surface automatically according to dark and the unclear situation of sight line.

3, night, the SELF CL country beam was opened the passing light illumination when street lighting is good; The SELF CL passing light was opened the country beam illumination when street lighting was bad.

4, two cars that travel in the same way, when driving to certain distance, the sensitization of tail-light before back car (by the back car of this device of dress) can be subjected to by the regulation of traffic regulation, the SELF CL country beam is opened passing light and is travelled.

5, range line warning at night: night is with the vehicle that travels, press this device of dress as front truck, when back car does not travel by this device of dress, the front truck of this device when travelling at a distance of certain distance, two cars is housed, will (this lamp can be in addition by dress with a wigwag, also can use other lamp repacking of afterbody) inform that afterwards car cuts out country beam, use passing light to travel; When back car speed of a motor vehicle height two car distance being travelled less than safety distance, front truck promptly sends a wigwag with back light to the back car, and the car Reduced Speed Now of warning back is to prevent rear-end collision.The back car become that light travels or two car spacings greater than safety distance after, warning light extinguishes automatically.

6, the control light of sending a car continuously: this device has increased time delay circuit in meeting automatic beam change circuit, postpone behind the meeting to open country beam, after continuous meeting is finished or the opposite come spacing to exceed 150 meters SELF CL passing lights, the conversion country beam travels.

7, turn to change light: in this device, adopt to become light and turning flash interlock measure, make automobile when turning to, automatically distance light be become passing light and travel.Turn to after finishing and to recover country beam with closing of steering indicating light and travel.

8, at vehicle when the bridge tunnel, this device is provided with and by force distance light is become dipped beam and travel, and finishes the back and recovers automatic meeting and become light.

9, when overtaking other vehicles, by changing the automatic conversion long-and-short distant light in position of change-over swith, make its alternately flicker send the signal of overtaking other vehicles to front truck, after overtaking other vehicles change-over swith put automatic meeting position.

The utility model advantage:

1, it is guiding theory with a tractor serves several purposes, to clocklike becoming light, as meeting become light, with the car automatic beam change, continuously meeting control light, with car automatically the function of warning realize automatic guidance.To irregular change light, as turning flash, turn to become light, overtake other vehicles become light, by the change light of bridge tunnel, for sending instruction, become the light function semiautomatic control of realization automatically by the people.

2, the voltage range of use is wide, can be in 12V ± 20% or 24V ± 20% or 24V ± 20% scope normal operation, various motor-driven that is convenient to 12V and 24V power line voltage is used under various voltage statuss.

3, this circuit adopts integrated circuit and advanced power device, makes it that volume is little, in light weight, highly sensitive, good reliability, vibration resistance, and it is few to consume number of devices.

4, contact pointless, noiseless, life-span are long.

5, the work of this device is not disturbed by factors such as electricity, magnetic, and is noiseless to other electrical equipment and communications service yet.

6, this circuit is more relatively poor to the sensitization of cold light, but still can satisfy the requirement of automatic beam change.
