具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是 机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
可以理解的，电动汽车中的变色天窗玻璃通常呈现为曲面状，且相对于水平方向具有一最高点。同时，变色天窗玻璃包括一穿过最高点的分割线，分割线大致沿电动汽车的车宽方向延伸。分割线上的任意一点，均为其自身所在沿电动汽车车身长度方向连线的最高点。
如图1所示，为现有变色天窗玻璃中柔性电致变色器件的结构示意图。其中，柔性电致变色器件包括可视区域和位于可视区域外侧的遮蔽区域。其中，O′点为变色天窗玻璃的最高点在柔性电致变色器件上的投影点。直线M′为分割线在柔性电致变色器件上投影所在的直线。B′点为直线M′一侧，柔性电致变色器件边缘距离O′点最近的点。D′点为直线M′另一侧，柔性电致变色器件边缘距离O′点最近的点。在将柔性电致变色器件贴合于变色天窗玻璃的曲面玻璃上时，柔性电致变色器件会在边缘位置，特别是在靠近B′点和D′点附近出现明显的褶皱。从而影响柔性电致变色器件对应位置的性能，使得柔性电致变色器件出现膜层分离等问题而引起变色功能失效。随着时间的延长，柔性电致变色器件的失效面积也会不断扩大，影响变色天窗玻璃的正常使用。另外，由于褶皱的存在，也会影响变色天窗玻璃的外观形态，影响用户体验。
如图2所示，实施例中提供了一种调光装置，可明显改善边缘褶皱问题。
在一些实施例中，调光装置可以是电动汽车、燃油车、混合动力汽车等交通工具中具有调光功能的天窗玻璃。
当然，在另一些实施例中，调光装置还可以是住宅房屋、商场、厂房、实验室等场所具有调光功能的窗玻璃等结构。
相应的，实施例中，调光装置可以呈现为曲面状，且调光装置可包括一相对于水平面的最高点，以及穿过该最高点的分割线。
如图2所示，调光装置可以包括依次层叠设置的第一玻璃板210、调光器件100和第 二玻璃板310。其中，第一玻璃板210与调光器件100之间可以通过第一粘接层220粘接连接，第二玻璃板310与调光器件100之间可以通过第二粘接层320粘接连接。可以理解的，在调光器件100的周向边缘可环绕设置有一圈密封件400，为调光器件100的提供水汽隔离作用。密封件400可以位于第一粘接层220与第二粘接层320之间。调光装置中的第一玻璃板210、调光器件100和第二玻璃板310均可呈现为曲面状。
在一些实施例中，第一粘接层220和第二粘接层320均为光学透明粘接材料，例如，第一粘接层220和第二粘接层320均可以是光学胶(Optically Clear Adhesive，OCA)、固态光学胶(Solid Optically Clear Adhesive，SCA)、离子性中间膜(Surper Safe Glas，SGP)、液态光学胶(Liquid Optical Clear Adhesive，LOCA)、聚乙烯醇缩丁醛酯(Polyvinyl Butyral，PVB)等粘接材料中的一种或多种组合。
密封件400可选用具有绝缘且隔绝水氧效果的胶水。例如，压敏胶、热熔胶、紫外固化胶、热固化胶或紫外加热双固化胶等胶水中的一种或多种。当然，密封件400还可选用光学胶、固态光学胶、离子性中间膜、液态光学胶等粘接材料中的一种或多种组合，即密封件400可以与两粘接层的材料相同。
在一些实施例中，在第一玻璃板210靠近调光器件100的一侧设置有遮挡件230，遮挡件230可靠近第一玻璃板210的周向边缘设置有一圈。遮挡件230可以对调光器件100的周向边缘进行部分遮挡，从而使得调光器件100呈现出可视区及环绕可视区周向的遮挡区。
可以理解，在调光器件100未装配于两玻璃板之间时，调光器件100可呈现为平板状。图3至图14可为调光器件100未装入两玻璃板之间时相应的结构示意图。
如图3和图4所示，在一些实施例中，调光器件100可以包括调光膜片10，调光膜片10可以呈现为板状结构。实施例中，调光膜片10可以包括第一区11和第二区12，第二区12环绕设置于第一区11的周向。其中，第一区11可对应调光器件100的可视区，相应的，第二区12可对应调光器件100的遮挡区。
实施例中，调光膜片10还包括一预设点O及预设分割线M。其中，预设点O可为调光装置的最高点在调光膜片10上的投影点。预设分割线M可以为调光装置的分割线在调光膜片10上投影所在的直线。可以理解的，预设点O位于预设分割线M上。相应的，预设分割线M可以将调光膜片10分成第一部分10a和第二部分10b。
在一些实施例中，在第一部分10a一侧，A1A2≤OB1-L1。
其中，A1代表第二区12的外轮廓线在第一部分10a中距离预设点O最远的点。A2代 表线段OA1与第一区11的外轮廓线的交点。B1代表第二区12的外轮廓线在第一部分10a中距离预设点O最近的点。L1代表第一区11的外轮廓线在第一部分10a中与预设分割线M的最大垂直距离。在一些实施例中，线段OB1与第一区11的外轮廓线相较于B2，L1可以等于线段B1B2的长度。
相对应的，在第二部分10b一侧，C1C2≤OD1-L2。
其中，C1代表第二区12的外轮廓线在第二部分10b中距离预设点O最远的点。C2代表线段OC1与第一区11的外轮廓线的交点。D1代表第二区12的外轮廓线在第二部分10b中距离预设点O最近的点。L2代表第一区11的外轮廓线在第二部分10b中与预设分割线M的最大垂直距离。在一些实施例中，线段OD1与第一区11的外轮廓线相较于D2，L2可以等于线段D1D2的长度。
可以理解的，在调光装置中，第一区11的面积及形状通常是相对固定的，以适应交通工具等结构中的设置需要。
实施例中，在预设分割线M的两侧，分别使得A1A2≤OB1-L1及C1C2≤OD1-L2。从而，可使线段OB1的长度和线段OA1的长度趋于相等，使得线段OD1的长度和线段OC1的长度趋于相等，进而使得B1点和A1点趋向位于同一弧上，使得D1点和C1点趋向位于同一弧上。
进而，在将调光器件100贴合于两玻璃板之间时，可使调光膜片10边缘产生褶皱的应力趋于均匀分布，而非集中于B1点和D1点附近，即可减少应力的集中。另外，均匀分布的应力可通过调光膜片10自身的张力相互抵消，以致消除调光膜片10边缘褶皱的产生，即可改善调光器件100边缘的褶皱问题。一方面，可减少褶皱带来的调光性能失效问题，延长调光装置的使用寿命。另一方面，也可改善调光装置的外观形态，改善用户体验。
实施例一
如图3和图4所示，在一些实施例中，第一区11可以大致呈现为长方形。相应的，第一区11的外轮廓线可以包括环绕长方形周向依次设置的第一轮廓部111、第二轮廓部112、第三轮廓部113和第四轮廓部114。实施例中，第一轮廓部111、第二轮廓部112、第三轮廓部113和第四轮廓部114均可为直线段。
在一些实施例中，第一轮廓部111可位于第一部分10a，第三轮廓部113可位于第二部分10b。第二轮廓部112和第四轮廓部114均可由第一部分10a延伸至第二部分10b。实施例中，第一区11的外轮廓线还可以包括四个圆弧轮廓部115。相应的，在第一轮廓部111、 第二轮廓部112、第三轮廓部113和第四轮廓部114中，任意相邻两轮廓部之间均可通过一圆弧轮廓部115连接。实施例中，圆弧轮廓部115可以向远离预设点O的方向凸出。
当然，在另一些实施例中，第一区11也可呈现为正方形。第一轮廓部111、第二轮廓部112、第三轮廓部113和第四轮廓部114中，任意相邻两轮廓部之间也可直接连接。

在一些实施例中，第二区12的外轮廓线还包括有四个圆弧轮廓线段125。第一轮廓线段121、第二轮廓线段122、第三轮廓线段123和第四轮廓线段124中，任意相邻两轮廓线段之间均设置有一圆弧轮廓线段125。从而，以促使A1A2≤OB1-L1及C1C2≤OD1-L2，改善调光装置边缘出现的褶皱问题。实施例中，圆弧轮廓线段125可以向远离预设点O的方向凸出设置。
如图5和图6所示，进一步的，在一些实施例中，调光器件100可以是电致变色器件。在外电场及电流的作用下，电致变色器件中相应的材料可以发生可逆的氧化还原反应，使得材料结构发生改变，进而使电致变色器件的吸收光谱和光学性能(例如吸收率、透射率和反射率等)发生变化，以实现光线调节功能，在外观上呈现为颜色及透明度的可逆变化。
当然，在另一些实施例中，调光器件100还可以选用光致变色、热致变色、气致变色、液晶面板等具有调光功能的面板结构。
相应的，实施例中，调光器件100还包括汇流条组件20，可以实现调光膜片10的供电。
再一并结合图7所示，在一些实施例中，调光膜片10可以包括依次层叠设置的第一透明基板141、第一导电层142、变色材料层110、电解质层120、离子储存层130、第二透明基板151和第二导电层152。其中，第一导电层142和第二导电层152均可电连接有汇流条组件20。即，调光器件100包括两组汇流条组件20，分别用作调光器件100的正负极。
实施例中，第一透明基板141和第二透明基板151均可为柔性结构。在一些实施例中，第一透明基板141和第二透明基板151均可由聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，PET)、环烯烃共聚物、三醋酸纤维素、玻璃和金属中的一种或多种制成。
第一导电层142和第二导电层152均可由氧化铟锡(Indium-Tin Oxide，ITO)、氧化锌铝(Aluminum Zinc Oxide，AZO)、氟掺杂氧化锡(Fluorine Doped tin Oxide，FTO)、银纳米线、石墨烯、碳纳米管、金属网格或银纳米颗粒等材料中的一种或多种制成。
变色材料层110可以选用凝胶态电致变色结构，亦或，单层或多层的全固态电致变色结构等。电解质层120和离子储存层130均可采用现有技术中已经公开的材料，在此不做赘述。
如图8所示，汇流条组件20可通过电极引线202连接于对应的导电层。在一些实施例中，调光膜片10上开设有连通导电层的容腔，电极引线202可穿设于容腔中并与对应的导电层电连接。
在一些实施例中，两组汇流条组件20可设置为相同，以其中一组为例进行详细说明。
如图5所示，汇流条组件20可以包括第一汇流条21、第二汇流条22、第三汇流条23和第四汇流条24。在一些实施例中，第一汇流条21、第二汇流条22、第三汇流条23和第四汇流条24可沿着一长方形的四边连续设置，且各汇流条之间均电连接。从而，汇流条组件20可通过一个引出电极接出，以连接电源等。相应的，任意相邻两汇流条的连接处，可形成直角的转折部201。在一些实施例中，汇流条组件20可为一体设置，任意相邻两汇流条之间可通过弯折进行转向，以方便汇流条组件20的布设。实施例中，汇流条组件20可选用具有胶层的铜箔、银线等。
在另一些实施例中，四个汇流条也可为分体设置，相邻两汇流条之间可通过焊接等方式实现机械连接及电连接。
一并结合图4和图5，在一些实施例中，汇流条组件20可以布设于调光膜片10的周向边缘。第一汇流条21可布设于第一轮廓线段121位置，第二汇流条22可以布设于第二轮廓线段122位置，第三汇流条23可布设于第三轮廓线段123位置，第四汇流条24可以布设于第四轮廓线段124位置。同时，各汇流条的端部均相对于所在轮廓线段凸出设置。
如图5所示，调光膜片10还包括若干个镂空区13。在一些实施例中，调光膜片10包括四个镂空区13，四个镂空区13与四个转折部201一一对应设置。镂空区13可位于第二区12与转折部201之间，即镂空区13可位于对应的圆弧轮廓线段125与对应的转折部201之间。在一些实施例中，镂空区13可遍及第二区12与转折部201之间的区域。
如图9所示，在另一些实施例中，镂空区13可占用第二区12与转折部201之间区域的部分，且靠近第二区12一侧设置。
如图4和图5所示，以第一汇流条21为例，可以理解的，沿垂直于预设分割线M的 方向，第一汇流条21具有一定的宽度，且第一汇流条21需要由相应宽度的膜层结构承接。在一些实施例中，第一汇流条21远离预设点O的一侧边可与第二区12中的第一轮廓线段121相齐平，且第一汇流条21的两端可相对于第一轮廓线段121凸出。位于第一部分10a中的圆弧轮廓线段125，靠近第一轮廓线段121的一端部可位于第一汇流条21靠近预设点O的一侧。相应的，在垂直于预设分割线M的方向上，可使第一轮廓线段121的端部，与对应圆弧轮廓线段125中相对的端部断开且错位设置，且错位距离可大于或等于第一汇流条21的宽度。
在制作调光膜片10时，可先提供一完整的长方形电致变色膜片。随后，可在镂空区13所对应位置对电致变色膜片进行刻蚀或切割等操作，以去除镂空区13位置处的膜层结构。可以理解的，镂空区13可以是开设于调光膜片10上的通孔结构。通过设置镂空区13，可使遮挡区轮廓线在第一部分10a和第二部分10b中距离预设点O最远的点，向靠近预设点O的方向偏移，以可缩短A1A2的距离。从而，可确保调光膜片10满足A1A2≤OB1-L1及C1C2≤OD1-L2，以改善调光装置边缘出现褶皱的问题，同时保证了设置汇流条的便利性，因为此时汇流条是直线设置的，增大了生产的便利性。
如图6所示，在一些实施例中，镂空区13中可填充有支撑结构30。可以理解的，调光膜片10贴合于两玻璃板之间后，镂空区13中填充有支撑结构30，可避免调光装置的各膜层中出现部分悬空，调光装置的各部位均得到有效可靠的支撑，减少调光装置的损坏几率。同时，也可方便将调光膜片10贴合于两玻璃板之间。
可以理解的，调光膜片10可以包括两个相背的表面。在一些实施例中，支撑结构30可相对于调光膜片10的两个表面齐平设置。
在另一些实施例中，支撑结构30也可相对于调光膜片10的任一表面凸出设置。
当然，在另一些实施例中，支撑结构30也可相对于调光膜片10的任一表面凹陷设置。在将调光膜片10贴合于两玻璃板之间时，支撑结构30相对于调光膜片10表面的凹陷位置可由对应的粘接层进行补充。
在一些实施例中，支撑结构30也可由光学胶、固态光学胶、离子性中间膜、液态光学胶、聚乙烯醇缩丁醛酯等粘接材料中的一种或多种制成。
如图10所示，在另一些实施例中，汇流条组件20也可沿着第二区12的外轮廓线进行布设。相应的，相邻两汇流条之间可通过圆弧形进行过渡衔接。相应的，调光膜片10上可无需设置镂空区13。
如图11所示，在另一些实施例中，第一汇流条21、第二汇流条22、第三汇流条23和第四汇流条24也可彼此间断设置。汇流条组件20也可布设于第二区12内，即位于第一区11的外轮廓线与第二区12的外轮廓线之间的位置，且不与第二区12的外轮廓线接触。相应的，各汇流条可各自连接一引出电极进行接出，以分别连接电源等。
在另一些实施例中，汇流条组件20可包括一个、两个或三个等数量的汇流条，且各汇流条均可为直线形状。汇流条组件20可沿长方形的部分侧边进行布设。相应的，汇流条组件20可对应包括一个、两个等数量的转折部201。调光膜片10上也可开设有与转折部201数量相等的镂空区13。
实施例二
如图12所示，与实施例一的不同点在于：
再一并结合图4，第一轮廓线段121和第三轮廓线段123均为弧线段。具体的，第一轮廓线段121靠近B1点的位置向远离第一轮廓部111的方向弯曲凸出。第三轮廓线段123靠近D1的位置向远离第三轮廓部113的方向弯曲凸出。从而，可延长线段B1B2的长度及线段D1D2的长度，以使A1A2≤OB1-L1及C1C2≤OD1-L2。
实施例中，第一轮廓线段121的两端可直接连接于第二轮廓线段122和第四轮廓线段124的对应端部。第三轮廓线段123的两端也可直接连接于第二轮廓线段122和第四轮廓线段124的对应端部。
实施例三
如图13所示，与实施例二的不同点在于：任意相邻两轮廓线段之间均可通过一圆弧轮廓线段125连接。圆弧轮廓线段125向远离预设点O的方向弯曲凸出。
实施例四
在一些实施例中，调光器件100的可视区可根据交通工具中调光装置的需要设置有向预设点O方向靠近的凹槽结构。
如图14所示，实施例中，第一区11的外轮廓线还包括异形轮廓部116，异形轮廓部116可设置于第一轮廓部111、第二轮廓部112、第三轮廓部113或第四轮廓部114。
在一些实施例中，异形轮廓部116可设置于第一轮廓部111处。可以理解的，沿第一轮廓部111的延伸方向，异形轮廓部116可根据需要设置于第一轮廓部111的中部或任一端部等位置。实施例中，异形轮廓部116可以是向预设点O方向靠近的凹槽形状。
实施例中，第二区12的外轮廓线可根据实施例一至实施例三中提供的方式进行设置。
