Automobile sun shading device and method

Abstract

The invention provides an automobile sun shading device which comprises a dimming film integrated to automobile glass and a control system electrically connected with the dimming film. The control system can start an intelligent dimming function or a manual dimming function according to a received command, send an adjustment and control signal to the dimming film according to illumination intensity information of the dimming film when the intelligent dimming function is started and send the adjustment and control signal to the dimming film according to a manual dimming control command when themanual dimming function is started, wherein the dimming film can adjust the light transmittance according to the received adjustment and control signal. The dimming film capable of adjusting the light transmittance is integrated to the automobile glass, and compared with a traditional solid sun shading device (a sun shield or a sun shading curtain), the automobile sun shading device occupies a small effective space in an automobile; and the light transmittance of the dimming film can be intelligently or manually controlled, a sun shading effect is well achieved, and meanwhile, the individuation requirements of users are met. The invention further discloses an automobile sun shading method.

Description

technical field [0001] The invention relates to the field of dimming devices for vehicle windows, in particular to an automobile sunshade device and an automobile sunshade method. Background technique [0002] With the continuous improvement of people's living standards, private cars have become more and more popular in families. In order to block the strong sunlight, private cars are equipped with sun visors or sunshade curtains, which can be opened and used when the sunlight is strong, so as to avoid the adverse effects of strong light on driving or the excessive temperature inside the car caused by strong light, which will affect Driving experience, or turn it on when passing through a tunnel or driving at night to block the high beam light, avoid the impact of strong high beam light on driving, and prevent car accidents caused by the oncoming vehicles that cannot avoid high-speed driving. [0003] However, at present, the sun visors and sun shades in the car are relativ...

AI Technical Summary

Problems solved by technology

[0003] However, at present, the sun visors and sun shades in the car are relatively simple in form, and the shaded area is solidified, so it will affect the safety of driving during the day and meeting at night and the comfort of riding; moreover, the structural layout of the sun visor has large limitations. It will occupy the effective space in the car, greatly interfere with the styling design of other parts of the car, and even destroy the integrity of the vehicle shape
