Abstract

The utility model relates to an automatic light screen used in night meeting between automobiles, comprising a photocell inductor, a light screen, gearwheels, a reversible driving system and a control circuit. The utility model is characterized in that the manufacturing, usage and maintenance are simple, and the insufficiency in the prior art is overcome. The utility model can avoid blindsight driving caused by strong light at night and can automatically control the automobile for reducing the frequent operating fatigue of drivers. The utility model can also be exploited and used as an automatic control system of other products.

Description

Automatic light visor used in night meeting berween automobiles

The utility model belongs to mechanical electric apparatus manufacturing technology field, relates to the automation electric apparatus control apparatus.

For a long time, all be devoted to research and solve the method and apparatus of power actuated vehicle night safe meeting both at home and abroad, stimulate, guarantee the safety of driving, but effect is all undesirable so that the driver avoids dazzling high light.As install passing lamp, conversion illumination distances, the light intensity that weakens additional, polaroid etc. is installed.

The purpose of this utility model, utilize the principle of linear propagation of light exactly, a self-adjustable anti-dazzle device is installed in the automotive lamp upper edge, protract to certain position at anti-dazzle device, anti-dazzle device has just covered the upwards angle of irradiation of car light light, thereby make the other side's driver vision directly not be subjected to the irradiation of dazzling high light, thereby avoid producing blind looking, the nighttime meeting particularly of causing driving a vehicle dangerous because of light irradiation makes chaufeur.

Feature of the present utility model, be that front end at self-propelled vehicle is provided with the photoemissive element inductor over against the place ahead, it can start reversible micromotor running by control path, and drive is positioned at the telescopic moving of the anti-dazzle device of car light upper edge through gear transmission, reaches the purpose of shading.

Fig. 1 is the structural representation of the designed automatic anti-dazzle device of self-propelled vehicle vehicles meeting at night of the utility model, and Fig. 2 is the control path principle example figure of automatic anti-dazzle device.As can be seen from Figure, control path can adopt multiple version, and accompanying drawing is a kind of example that the application provides, and it can use the power supply on the self-propelled vehicle.

The automatic anti-dazzle device of the designed self-propelled vehicle vehicles meeting at night of the utility model, by reversible miniature motor 1, photoemissive element inductor 2, protective case 3, relay 7, anti-dazzle device that has tooth bar 54 on connection and the gear 8 and circuit control desk 6 constitute.Its principle of work is, when the photoemissive element inductor receives the lightwave signal that the place ahead is come, produce the base stage that photovoltaic voltage imports crystal triode in the control path into, base stage obtains trigger voltage, discharges the adhesive of the current drives relay that has amplified, thereby makes and the reversible micromotor of normal opened contact bonded assembly is connected, micromotor rotates, anti-dazzle device is released,, continued to stay for some time through time delay circuit control.Meeting finishes, and relay disconnects, the normally closed contact conducting, and the micromotor reversing sense rotates, and anti-dazzle device is resetted, and anti-dazzle device resets and locates to be equipped with limit switch, with the micromotor circuitry cuts that reverses, has finished a circulation automatically, and is capable of circulation according to this reciprocal.

The manufacturing of the present utility model, working service are all very simple; Installing does not influence the attractive in appearance of former self-propelled vehicle external form again; Cheap.This device again can automatic guidance complete operation voluntarily, thereby reduce the chaufeur night travel greatly, work loads such as road speed are controlled in headlamp switch operation frequent during meeting frequently, its effect is significant.The utility model also can be used for Vehicular lamp and prevents keeping off the rain, avenging; Can be connected a shared system with the windshield scraper plate; Be developed to other automatic guidance products etc.

Claims

1, the automatic anti-dazzle device of a kind of self-propelled vehicle vehicles meeting at night, it is characterized in that, the anti-dazzle device of a band tooth bar guide rail is housed in the car light upper edge, be connected in reversible micromotor with gear on, and over against the place ahead device the photoemissive element optical inductor is arranged at the car front end, it can start reversible micromotor by control path, makes the anti-dazzle device telescopic moving.

According to the described automatic anti-dazzle device of claim 1, it is characterized in that 2, the gear driven anti-dazzle device is by limit switch and the control of relay time delay circuit.
