Abstract

The invention relates to an automobile sunshading board with a function of automatically adjusting light transmittance. The automobile sunshading board is characterized by comprising a fixed bracket, a shell, a circuit board with a photosensitive device and a liquid crystal light valve plate, wherein the fixed bracket comprises a left fixed bracket and a right fixed bracket; the left fixed bracket is arranged on the left upper side of the shell; the right fixed bracket is arranged on the right upper side of the shell; the circuit board with the photosensitive device is arranged in the shell; the liquid crystal light valve plate is clamped into a mounting gap of the shell; and a driving interface of a liquid crystal light valve driving circuit is connected with the circuit board with the photosensitive device. The automobile sunshading board has the advantages that: a liquid crystal light valve serves as a light-transmitting device and the photosensitive device is used for automatically adjusting the light transmittance, so that stimulation to a driver caused by the external light is reduced, visual field of the driver is effectively enlarged, manual operation strength of the driver is reduced, and safety of the driver is improved.

Description

technical field [0001] The invention relates to an automobile sun visor with the function of automatically adjusting light transmittance, which uses a liquid crystal light valve to automatically adjust the light transmittance of the automobile sun visor, and belongs to the technical field of automobile electronic accessories. Background technique [0002] Car sun visors are used to block the light that hits the driver, but the traditional completely opaque blocking method will cause an image of the driver's field of vision, which is not conducive to driving safety. Contents of the invention [0003] The invention proposes an automobile sun visor with the function of automatically adjusting the light transmittance. Its purpose is to use the liquid crystal light valve as a device to change the light transmittance, and to change the transmittance of the light valve by changing the voltage applied to the liquid crystal light valve. The light rate, and then use the photosensiti...
