The sun-shading and anti-dazzle device comprises a plurality of optical sensors, a plurality of liquid crystal units and an electric control dimming unit, wherein the optical sensors are arranged in the control areas respectively and sense the light intensities of the area where the optical sensors are located; the liquid crystal units are arranged in the automobile glass in a clamped mode and correspond to the control areas of the optical sensors one to one; the electric control dimming unit is connected with the optical sensors and the liquid crystal units and adjusts the light transmittance of the corresponding liquid crystal units according to the light intensities sensed by the corresponding optical sensors. According to the sun-shading and anti-dazzle device, shading areas are adjusted according to the intensity of outside light, all the control areas can be shaded, and effective shading is achieved.
Description
[technical field]
The present invention relates to a kind of visor and antiglare equipment, particularly a kind of can the visor and antiglare equipment of effective shading.
[background technology]
The monoblock platy structure that anti-dazzle device commercially available mostly at present is light tight, does not have an X-rayed, although blocked the sunlight above from front vehicle window, has also sheltered from the visual field of driver.For increasing the safety and comfort level of driving, just occurring keeping the sun off, having made light no longer dazzling, do not affected again driver and to drive the automotive light-shading board of forward visibility.Such as, No. 201010207471.1st, China's Mainland patent application discloses a kind of antiglare night vision device for automobile and relates to vehicular spare parts, be specifically related to a kind of sun shield, comprise the sun shield plate body be connected with rotating shaft in an automobile, also comprise liquid crystal baffle, liquid crystal baffle is arranged on sun shield plate body, and liquid crystal baffle connects microprocessor system, and microprocessor system connects photosensor; Photosensor, for monitoring light intensity, sends microprocessor system to light intensity signal, when microprocessor system judges that light intensity increases suddenly, controls the electric signal at liquid crystal baffle two ends, reduces liquid crystal baffle light transmission, realizes anti-glare function.
Although, the antiglare night vision device for automobile that No. 201010207471.1st, China's Mainland patent application can prevent vehicle at night houselights or the luminous stimulation to driver's eyes of the sun in the scope of sun shield plate body, ensure that traffic safety, have that structure is simple, easy to use, visibility advantages of higher.But, if the incident scope beyond sun shield plate body of outside high light, then cannot effectively shading.
[summary of the invention]
Main purpose of the present invention be to provide a kind of can the visor and antiglare equipment of effective shading.
The invention provides a kind of visor and antiglare equipment, it is located in vehicle glass, and described vehicle glass divides some controles area; And described visor and antiglare equipment comprises:
Some optical sensors, it to be located at respectively in control area and to sense the light intensity of region;
Some liquid crystal cells, its to be located in vehicle glass and with the control area one_to_one corresponding of optical sensor;
Electric-controlled light-regulating unit, it connects optical sensor and liquid crystal cells, the light transmittance of the corresponding liquid crystal cells of light intensity regulating that electric-controlled light-regulating unit senses according to respective photosensor.
Especially, described vehicle glass is automobile front windowpane.

[detailed description of the invention]
Refer to shown in Fig. 1-4, the invention provides a kind of visor and antiglare equipment, it is located in vehicle glass, and in the present embodiment, described vehicle glass is automobile front windowpane or automobile side window glass.Described vehicle glass divides some controles area 100, and shape and the large I of control area 100 set as required.Described visor and antiglare equipment comprises:
Some optical sensors 20, it to be located at respectively in control area 100 and to sense the light intensity of region;
Some liquid crystal cells 30, its to be located in vehicle glass and with the control area one_to_one corresponding of optical sensor 100;
Electric-controlled light-regulating unit 40, it connects optical sensor 20 and liquid crystal cells 30, and the light transmittance of the corresponding liquid crystal cells 30 of light intensity regulating that electric-controlled light-regulating unit 40 senses according to respective photosensor 20.
Electric-controlled light-regulating unit 40 is utilized to change the voltage swing of liquid crystal cells 30 to change the light transmittance of liquid crystal cells 30, as shown in Figure 2, when extraneous light intensity does not exceed preset range, electric-controlled light-regulating unit 40 does not pressurize to liquid crystal cells 30, now, liquid crystal cells 30 is in full impregnated state; As shown in Figure 3-4, when extraneous light intensity exceeds preset range, high light as light-struck in vehicle at night illuminating lamp or the high light shined upon daytime, voltage added on the light intensity regulating liquid crystal cells 30 that electric-controlled light-regulating unit 40 senses according to optical sensor 20, the light intensity that optical sensor 20 senses is larger, when voltage then added by electric-controlled light-regulating unit 40 pairs of liquid crystal cells 30 is larger, the light transmittance of liquid crystal cells 30 is lower.
Be automatic control mode according to the pattern that the light intensity of optical sensor 20 is made adjustment, in addition, also can increase MANUAL CONTROL mode, user can switch automatic control mode or MANUAL CONTROL mode as required.Under MANUAL CONTROL mode, electric-controlled light-regulating unit 40 no longer according to the light transmittance of the light intensity regulating liquid crystal cells 30 of optical sensor 20 sensing, but regulates the light transmittance of corresponding liquid crystal cells 30 according to the control area 100 manually selected.
Visor and antiglare equipment of the present invention emphasizes whole lightproof area according to ambient light, to the shading of all controles area 100, thus can reach effective shading.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
