Problems solved by technology

Some use sub-regional adjustment of the grayscale of the light-transmitting plate to block the strong light. This device uses a micro-camera to collect the light source of the vehicle in front, and determines the position of the light source through image processing, and then determines the part that needs to be blocked on the light-transmitting plate. This device The structure is complicated and the cost is high, the image processing effect is relatively poor and time-consuming, and it is difficult to popularize and use. Therefore, an anti-glare glare car sun visor with a simple structure and good blocking effect is needed

Embodiment 1

[0028] As shown in the figure, the automatic anti-glare device provided by this embodiment includes a fixed bracket, a filter plate and a control circuit; the fixed bracket is fixed on the frame; the filter plate is arranged on the fixed bracket; the filter plate It includes a main body 1, a light-changing sheet, a light guide pipe 2 and a photosensitive part; the photosensitive part of this embodiment can use a photosensitive element 5;

[0029] The light pipe 2 is arranged on the main body 1 at the intersection of the observer's eye line of sight according to the eye angle 4; the axial direction of the light pipe 2 is arranged along the direction of the incident light; the eye angle 4 is the light emitted by the light source. The angle between the light 24 that enters the observer's eyes and the line of sight directly ahead of the observer's eyes; the light-changing sheet is arranged on the main body; the light-changing sheet is connected with the control circuit;

[0030] T...

Embodiment 2

[0059] The main body provided in this embodiment is made of transparent material, which can be transparent glass or transparent organic plastic; The pressing or pasting method is combined with the main body; the transparent film layer is divided into several areas according to the actual situation, each area is connected to the control circuit, and the light transmittance of each area is adjusted through the control circuit, and each area can be adjusted by changing the refractive index. To achieve the size of the light transmittance, the size of the light transmittance can also be realized by changing the color or grayness of each area.

[0060] The dimming area can be set as a first dimming area and a second dimming area; the first dimming area is the neighborhood where the line connecting the light source and the observer's left eye intersects with the subject; the second dimming area The domain is the neighborhood where the connection line between the light source and the ...

Embodiment 3

[0078] In the anti-glare dynamic monitoring device provided in this embodiment, the controller is also provided with a transmittance recovery module; the transmittance recovery module restores the transmittance of the light-changing area after receiving a signal that the transmittance intensity needs to be restored. The signal for restoring light transmittance intensity can be actively generated through a button, or can be controlled by a preset time value; when the dimming time of the dimming area is maintained according to the preset time threshold, the restoring signal is generated.

[0079] The rearview mirror provided by this embodiment can be provided with a detection field, which is the neighborhood where the light entering the viewer's eyes after being reflected by the rearview mirror and the intersection of the rearview mirror; It is arranged in the detection area on the rearview mirror; the axial direction of the light guide pipe is arranged along the direction of the...

Abstract

The invention discloses an automatic anti-dazzle device. The automatic anti-dazzle device comprises a fixed bracket, a light filter plate and a control circuit. The fixed bracket is fixed to a vehicle frame. The light filter plate is arranged on the fixed bracket and comprises a main body, a light changing piece, light guide pipes and a photosensitive part. The light guide pipes are arranged on the main body. The optical axes of the light guide pipes are arranged on propagation paths of light rays radiating into eyes of an observer. The photosensitive part is used for receiving the light rays penetrating through the light guide pipes and converting the light rays into an electrical signal. The light guide pipes are provided with a light absorbing layer. The electrical signal is input into the control circuit and used for driving the control circuit. The control circuit is connected with the light changing piece and used for adjusting the transmission of the light rays into the eyes of the observer when the light rays pass the light changing piece. According to the automatic anti-dazzle device, the light guide pipes are adopted to detect the dazzle direction and determine the position of dazzle irradiating on the main body, and a blocking part on the main body is rapidly determined; the structure is simple; operation is convenient; the situation that the eyes are dazzled due to strong light is prevented; and the view of a driver is not affected, so that the comfort of vehicle driving and the safety of driving are greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobile sun visors, in particular to a partition-adjustable anti-glare automobile sun visor. Background technique [0002] Cars meet at night, and the high beams of the oncoming cars are strongly irradiated, causing the driver's eyes to be dazzled instantly, making it impossible to judge the road conditions ahead normally, causing a great hidden danger to safety. In order to avoid this phenomenon, a sunshade and anti-glare filter plate is often used, which is composed of a photoelectric converter and a liquid crystal light valve; It can switch between different colors; the electric controller with photosensitive tube is installed on the liquid crystal glass, which can automatically change the color according to the luminosity of the opposite side. Some use sub-regional adjustment of the grayscale of the light-transmitting plate to block the strong light. This device uses a micro-camera to collect the ...
