Problems solved by technology

However, at present, most of the sun visors used in automobiles are a whole piece of opaque material, and you can only choose to cover the entire surface or not. When using it, the entire surface is blocked from the front light, which reduces the driver's field of vision and increases driving risks.

Embodiment

[0024] In this embodiment, the casing 10 is used for fixedly installing the first liquid crystal light valve, the second liquid crystal light valve 30 and the control circuit board 50, the front side of the casing 10 is the side facing the driver, and the rear side of the casing 10 is The side is the side facing the front of the vehicle, and a photosensitive sensor 70 is arranged on the rear side of the housing 10 .

[0025] The first liquid crystal light valve and the second liquid crystal light valve can adopt any random combination of TN positive structure, TN negative structure, TN negative + dye, and VA negative structure. Wherein the photosensitive sensor 70 can sense the intensity of light in front of the vehicle, and convert it into a first electrical signal and send it to the control circuit board 50; the control circuit board 50 sends the second electrical signal to the human eye tracking camera 60 according to the intensity of the first electrical signal; The tracki...

Abstract

The invention provides an automatic dimming sun visor, which includes a housing, a photosensitive sensor, a human eye tracking camera, a control circuit board, and a first liquid crystal light valve and a second liquid crystal light valve bonded together; the housing is used to fix the second liquid crystal light valve. A liquid crystal light valve, a second liquid crystal light valve and a control circuit board, the human eye tracking camera and a photosensitive sensor are arranged on the casing; the control circuit board is connected with the first liquid crystal light valve, the second liquid crystal light valve, the human eye The tracking camera and photosensitive sensor are electrically connected. The sun visor provided by the present invention can pass the signal transmission of the photosensitive sensor and the human eye tracking camera, so as to control the circuit board to apply electric signals to the first liquid crystal light valve and the second liquid crystal light valve, and control the luminous flux in different areas of the sun visor Effect: the driver can clearly see the driving situation of the vehicle in front, avoiding the impact of strong light on the driver's eyes directly on the driver's eyes, and improving the driving safety of the user.

Description

technical field [0001] The invention belongs to the technical field of intelligent vehicle equipment, and in particular relates to an automatic dimming sun visor with the function of a vanity mirror. Background technique [0002] With the progress and development of society, cars have become an irreplaceable means of transportation in people's daily life. The sun visor is a part of auxiliary driving. The impact of eye vision, improve driving safety. However, most of the sun visors currently used in automobiles are a whole piece of opaque material, and you can only choose whether to cover the entire surface or not. When in use, the entire surface is blocked from the front light, which reduces the driver's field of vision and increases driving risks. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic dimming sun visor with the function of a vanity mirror. Can be used for vanity mirror. [0004] In orde...
