[0003] 为了实现遮光目的,现有技术中可以采用以下两种方式: [0003] In order to achieve the purpose of shielding, the prior art can be used in two ways:

[0004] 第一,在车内前窗上部配置遮阳板,需要遮光时将该遮阳板翻下来,不用时则可以翻上去,以避免阳光直射眼睛,从而一定程度上可以改善驾驶视线。 [0004] First, the upper portion of the front window of the vehicle sun visor configuration, when the required shielding visor turned down, when not in use can be turned up, in order to avoid direct sunlight eyes, can be improved to a certain extent so that driving vision. 但是遮光板需要占据车内的空间,且美观性较差;此外驾驶员需要根据光照情况随时手动调节遮阳板的位置,不利于安全驾驶。 However, the light shielding plate need to occupy space in the vehicle, and the appearance is poor; in addition the driver to manually adjust the position of the sun visor according to the light conditions at any time, is not conducive to safe driving.

[0005] 第二,在车内前窗上部的挡风玻璃夹层中的塑料中间膜(如PVB膜)中添加颜色,以使对应的挡风玻璃变为不透明,从而可以避免阳光直射眼睛,达到遮光目的。 [0005] Second, a plastic intermediate film (e.g., PVB film) in the upper portion of the vehicle windshield interlayer front window color was added to make a corresponding windshield becomes opaque, thereby avoiding direct sunlight eyes, reaches shading purposes. 但是由于带有颜色的塑料中间膜始终存在,因此即使在光线较弱无需遮光的情况下,挡风玻璃仍为不透明,无法使外界光线透过来以提高车内光线强度,即此种方式无法进行调节,从而实用性差。 However, since the plastic film with the intermediate color is always present, even in a case where weak light without shading the windshield remains transparent, the outside light can not make the light intensity in order to improve the vehicle, i.e. in this manner can not be carried through adjusted so poor in practicability.

[0036] 正如背景技术部分所述,现有技术中用户可以通过遮阳板或带颜色的玻璃来实现遮光目的,但上述方式存在美观性差或实用性差的缺陷,最终不能简单有效调节玻璃的透光量。 [0036] As described in the background, the prior art user object can be achieved by shielding the sun visor or colored glass, but there is poor or poor practicality appearance defects described above, simply can not effectively adjust the final light-transmissive glass the amount.

[0037] 针对上述缺陷,本发明技术方案中先在与待遮阳位置对应的玻璃上设置聚合物分散液晶膜,接着获取所述玻璃当前的光强信息,最后为所述聚合物分散液晶膜提供与所述当前的光强信息对应的电压大小,从而通过调节为所述聚合物分散液晶膜提供的电压大小就可以调节对应玻璃的透光状态,既美观又实用,最终可以简单有效地调节玻璃的透光量,提高用户的舒适度。 [0037] For the above drawbacks, the first aspect of the present invention is provided in a polymer dispersed liquid crystal film to be shading position corresponding to the glass, and then obtain the current light intensity information of the glass, providing the final polymer dispersed liquid crystal film the magnitude of the voltage and current corresponding to the light intensity information, so that by adjusting the magnitude of the voltage to the polymer-dispersed liquid crystal film provided on a light-transmitting state can be adjusted corresponding to the glass, both aesthetic and practical, simple and effective adjustment eventually glass the amount of light transmission, improve user comfort.

[0038] 下面结合附图进行详细说明。 [0038] The following detailed description in conjunction with the accompanying drawings.

[0039] 参考图1所示,本实施方式提供了一种遮阳装置,包括: [0039] As shown in Figure 1, the present embodiment provides a shading device, comprising:

[0040]玻璃 100 ; [0040] Glass 100;

[0041] 设置在与待遮阳位置对应的所述玻璃100上的聚合物分散液晶膜200 ; [0041] The polymer on the glass is provided with shading position corresponding to 100 to be dispersed liquid crystal film 200;

[0044]所述聚合物分散液晶(Polymer Dispersed Liquid Crystal,F1DLC)膜200 是把预聚物与向列相液晶及衬垫料以某个比例混合起来,夹在两片柔性透明导电薄膜之间。 [0044] PDLC (Polymer Dispersed Liquid Crystal, F1DLC) film 200 is the material mixed at a certain ratio, sandwiched between two flexible transparent conductive film, and a nematic liquid crystal and a prepolymer between the spacer . 其工作原理为:不加电场时,无规则分布于聚合物材料中的液晶微滴的指向矢自由取向,此时由于液晶的寻常光折射率与聚合物的折射率不匹配,所以微粒对光有较强的散射作用,PDLC膜外观呈现不透明或半透明乳白状;当施加外电场作用后,由于正介电各向异性,所以液晶微粒的指向矢将沿外电场方向排列,如果液晶的寻常光折射率与聚合物的折射率匹配的话,光可以通过TOLC膜,从而TOLC膜将呈现透明状。 Its working principle is: when no electric field is randomly distributed to the director orientation of the polymer material consisting of liquid crystal droplets, since the refractive index of the liquid crystal at this time does not match the ordinary refractive index of the polymer, so that light particles strong scattering, a PDLC film exhibits an opaque or translucent appearance milky; when the external electric field is applied, since a positive dielectric anisotropy, the directors of the liquid crystal particles is arranged in the direction of the external electric field, if the liquid crystal vulgaris refractive index of the refractive index of the polymer match, TOLC light can pass through the membrane, thereby rendering TOLC transparent film. 具体地,施加在TOLC膜上的电压越大,所述TOLC膜越透明。 Specifically, the larger the applied voltage TOLC film, the more transparent the TOLC film.

[0045] 此外,所述TOLC膜中的液晶中还可以添加二色性染料,二色性染料沿着不同的轴具有不同的光吸收,因此具有不同的颜色,存在于液晶中的二色性染料分子的取向往往取决于主液晶,其对于本领域的技术人员是熟知的,在此不再赘述。 [0045] Further, the liquid crystal TOLC film may be added a dichroic dye, dichroic dyes having different light absorption along different axes, thus having different colors, a dichroic liquid crystal present in the depending on the orientation of dye molecules is often the main liquid crystal, which those skilled in the art are well known and not described herein again. 此时,当所述电源为所述聚合物分散液晶膜提供电压等于O时,与所述聚合物分散液晶膜对应位置呈现与所述二色性染料对应的颜色,从而在提高美观性的同时,用户根据自己的喜好可以进行更大空间的选择,最终进一步提高用户的体验效果。 At this time, when the power supply to provide the PDLC film voltage is equal to O, and the PDLC film exhibits a color corresponding to the position of the corresponding dichroic dye, thereby improving the appearance while the user can choose a larger space according to their preferences, and ultimately further improve the user experience effect.

[0046] 本发明充分利用I3DLC膜200的上述工作原理,在需要遮光时,调节器400调节电源300以使电源300为I3DLC膜200提供较小的电压,使对应玻璃100变为不透明或半透明,即使玻璃100的透光量较小;在不需要遮阳时,调节器400调节电源300以使电源300为TOLC膜200提供较大的电压,使对应玻璃100变为透明,即使玻璃100的透光量较大,从而可以简单有效地调节玻璃100的透光量,提高用户的舒适度。 [0046] The present invention fully utilizes the above-described operation principle I3DLC film 200, light shielding when necessary, the power regulator 400 adjusts the power source 300 to 300 200 to provide a smaller voltage I3DLC film, 100 of the corresponding glass becomes opaque or translucent , even a small amount of light-transmitting glass 100; shade when not needed, the regulator 400 adjusts the power supply 300 to the power source 300 provides a larger voltage TOLC film 200, 100 of the corresponding glass becomes transparent, even if the transparent glass 100 large amount of light, can be simply and effectively adjusting light amount of the glass 100, to improve user comfort.
