Description
Technical field
A kind of Vehicular multifunctional sunshading board that can actively reduce region luminous intensity is the utility model is related to, belongs to automotive engineering
Field.
Background technology
During vehicle is driven, the stronger situation of ambient can be run into, now typically using methods such as wear dark glasses
Reduce the irradiation of light, but band sunglasses with regard to not very convenient, can now use coloured screening for near-sighted personnel on car
Positive plate, or integral L CD sunshading boards, for the former just as sunglasses have been placed on into car glass rear, the decrease for light is
One customization, this block sunshading board can play opposite effect on the contrary if ambient is suddenly dimmed.And LCD sunshading boards then can
According to the change of ambient so as to adjust the optical attenuation value of oneself, light can be increased in the case where light dies down suddenly,
But this sunshading board can only use daytime, light-illuminating during for meeting at night just has no idea to cover.
The content of the invention
The purpose of this utility model is that deficiency, this practicality are new existing for masking meeting beam at night for common sunshading board
Type proposes a kind of Vehicular multifunctional sunshading board that can actively reduce region luminous intensity.
The technical solution of the utility model is a kind of Vehicular multifunctional sunshading board bag that can actively reduce region luminous intensity
Include glass substrate, liquid crystal array light shielding block, movable backlight module, backlight drive circuit, liquid crystal display drive circuit, power supply, shading
Glass working state monitoring circuit, other image data interface circuit, image and backlight control circuits, image processing circuit, take the photograph
Camera and laser radar.
The multifunctional sun visor is a rectangle tabular structure, and size is similar to traditional automobile cab sunshade
Plate, the first glass substrate and the second glass substrate are two block-shaped, size identical rectangle glass substrates；First glass substrate
The liquid crystal array light shielding block of installation is clipped with the second glass substrate；(leaning on driver side) passes through substrate on the outside of second glass substrate
The printed circuit flexible cord connection front glass working state monitoring circuit of laying；The output of front glass working state monitoring circuit
One input port of end connection liquid crystal display drive circuit；Liquid crystal array light shielding block connects liquid crystal by the printed circuit flexible cord of laying
Another input port of drive circuit；Movable backlight module is fixed on the top of car of sunshading board stowed position；The movable back of the body

Backlight control circuit；Power supply is powered to backlight drive circuit and liquid crystal display drive circuit respectively.
The liquid crystal array light shielding block forms liquid crystal array sunshading board with glass substrate.
The movable backlight module is a LED luminescent screen of the top of car for being fixed on sunshading board stowed position,
For providing backlight to LED screen.The glass when the liquid crystal array sunshading board that liquid crystal array light shielding block and glass substrate are formed is accepted
Glass substrate provides backlight by backlight module, comes out the presentation of information such as character for liquid crystal array sunshading board close to backlight module.Its
Contacted with glass substrate.
Video camera shoots external image, and image is sent into image processing circuit, image of the image processing circuit to feeding
In each object analyzed, brightness is marked out higher than certain object, and replaced with the suitable color lump of shape size bright
The higher object of degree, and the coordinate information of color lump is sent into image and backlight control circuit, then color lump coordinate information is sent into liquid
Brilliant drive circuit, it is by drive circuit that the state change of the liquid crystal shading point of relevant position in liquid crystal array sunshading board, decrease is outer
The stimulation of the strong light eyes in boundary；Whether image and backlight control circuit detect liquid crystal array sunshading board simultaneously in running order,
Backlight drive circuit is closed if in running order, backlight module is in OFF state, if detecting liquid crystal array
Sunshading board is in off working state then according to opening backlight drive circuit is set, and now liquid crystal array sunshading board can be changed into one piece
Display shows the data that other image data interface circuits are sent.
Front glass working state monitoring circuit is to monitor liquid by the extraordinary signal shown on liquid crystal array sunshading board
Crystalline substance screen whether circuit kit working properly, when liquid crystal array sunshading board is abnormal, this set circuit can be by liquid crystal array sunshade
The light transmittance of plate forces to be adjusted to pellucidity, and sends acousto-optic hint, support vehicles driving safety.
Laser radar can be come out vehicle front by the body scans of the strong light of other side's car light or shaded side, and in shading glass
The position that the people of vehicle is will be close on glass is outpoured with collimation mark to prompt human pilot to pay attention to someone at the outer shaded side of car or shadow.
It is in before the bright photoelectricity of same level position caused by liquid crystal array sunshading board that light blocking point blocks with human eye, allows this
Part light does not shine directly into the eyes of people.Simultaneously as the light blocking point shown on the mobile screen of bright luminous point is also with bright
Bright movement and move, until the luminous point that becomes clear removes the visual field of people, now light blocking point disappears automatically, for diffused light source, then liquid
Brilliant array sunshading board is in the state of integral light-transmitting degree reduction, so as to reduce the intervention of ambient, in ambient by bright change
Light transmittance dark and by control liquid crystal display that can be quickly by image processing circuit when becoming bright, allows the light into human eye to be in one
Individual perfect condition.
The beneficial effects of the utility model are that the utility model is entered by multifunctional sun visor to the higher source luminance in the external world
Row selectively masking, allow liquid crystal array sunshading board rear observer eyes without wear sunglasses in the case of reduce
Strong light then injures to eyes, therefore will not produce the strong light of point-like without processing simultaneously for the light of other positions and lead
All light is caused to be blocked.
