A car sunshade that reduces the influence of high beam lights when passing cars

Abstract

The invention discloses an automobile shading cover for weakening the influence of high beam lights when meeting vehicles, which comprises a base, a front cover panel and a focus plane, the focus plane is installed on the left side of the front cover panel, and the focus plane is provided with a movable shaft, which is fixed A micro-motor is connected, a limited reflector is hinged on the movable shaft, and the top and bottom of the focal plane are respectively fixedly connected with a first shading plate and a second shading plate, the first shading plate is installed inside the front cover panel, and the second shading plate Connected to the inner bottom of the front cover panel, the micro motor is installed inside the base, a thick lens is installed in the middle of the front cover panel, a photometric device is installed on the top of the front cover panel, and a lamp holder is installed on the top left end of the base. A reflective surface is provided, and the top of the reflective surface is provided with an LED light group, and the right side of the lamp holder is provided with a concave arc-shaped projection arc surface, which is used for light detection when meeting cars, and quickly interferes with the deflection angle of the lights emitted by the two car lights , covering the light in the forward direction of the car body.

Description

technical field [0001] The invention relates to the technical field of high-beam lamp control for automobiles, in particular to an automobile shading cover for reducing the influence of high-beam lamps when meeting vehicles. Background technique [0002] When the driver is driving at night, if the headlights of the car driving on the opposite side are illuminated by high beams, the driver will feel that the light is dazzling, which will affect driving safety. Current domestic research mainly focuses on anti-glare technology such as using polarized light to prevent glare. The light transmittance of the polarizer is very unsatisfactory, and the light transmittance of a single sheet is only about 36%. Therefore, it is necessary to increase the power of the car light and improve the brightness of the car light. This method has not yet reached the practical level due to the performance of the polarizer. Some intelligent dimming car headlights have the function of automatically sw...

Problems solved by technology

[0002] When the driver is driving at night, if the headlights of the car driving on the opposite side are illuminated by high beams, the driver will feel that the light is dazzling, which will affect driving safety. Current domestic research mainly focuses on anti-glare technology such as using polarized light to prevent glare. The light transmittance of the polarizer is very unsatisfactory, and the light transmittance of a single sheet is only about 36%. Therefore, it is necessary to increase the power of the car light and improve the brightness of the car light. This method has not yet reached the practical level due to the performance of the polarizer. Some intelligent dimming car headlights have the function of automatically switching the high beam to low beam when the oncoming vehicle is coming, but this kind of product cannot control the oncoming vehicle. Without this device on the oncoming vehicle, there is no guarantee that the oncoming vehicle will switch its high beam to low beam. We just make the vision of the oncoming vehicle clear, but we may still be troubled by the dazzling headlights on the opposite side:

[0003] Most of the mechanical high-beam anti-glare headlights at the present stage adopt a single-channel design, which can only block the light directed at an oncoming vehicle. It is difficult to realize multi-channel and multi-channel design; the structure of matrix headlights is complex, Large amount of data processing, high cost, difficult to popularize in mid-end cars
