具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
在对本公开实施例提供的调光玻璃及其制造方法进行详细说明之前，有必要对于相关技术进行以下说明：
在相关技术中，染料液晶调光玻璃需要设计为中空钢化玻璃结构，主要包括相对设置的室外侧钢化玻璃和室内侧钢化玻璃、及夹在室外侧钢化玻璃和室内侧钢化玻璃之间的调光功能层，在室外侧钢化玻璃和室内侧钢化玻璃之间还设置铝框和固定胶，铝框和固定胶围绕调光功能层的四周侧设置，调光功能层的电连接部分集成于调光玻璃结构中。
在相关技术中，调光功能层的电连接部分的固定方式是：调光功能层的绑定电路板外侧直接连接印刷电路板，印刷电路板通过卡扣固定在玻璃基板上，印刷电路板上焊接有导电引线，导电引线暴露于调光玻璃侧面。在将调光玻璃安装至建筑外立面和采光顶过程中，安装施工过程相对暴力，例如，会将调光玻璃强行推入并内嵌至金属型材中，导致电连接引线在调光玻璃侧面与金属型材之间受到挤压和拉扯，进而将拉扯力传递至印刷电路板和绑定 电路板上，导致电连接松动引起导通异常，最终使安装后的调光玻璃出现调光不良现象(例如无法点亮或者接触不良)，且该不良现象高发。后期对安装后的不良调光玻璃拆卸维修麻烦且危险，更换成本高昂，因此，调光玻璃在安装过程中导致电连接失效的问题亟待解决。
为了解决上述问题，在一些相关技术中，调光功能层主要包括上、下基板和位于上、下基板之间的液晶层，通过在上、下基板上分别开设凹槽，导电引线置于凹槽内，通过上、下基板对凹槽内的导电引线进行挤压固定。但是这种方式仅是针对调光功能层结构来所，对于调光玻璃来说，其还包括室内侧玻璃和室外侧玻璃，仅利用调光功能层的上、下基板上开设凹槽已无法实现固定导电引线的效果，且需要对上、下基板开槽，增加了制作工序，产生额外费用，且在合片工序中，由于上、下基板在开槽区域存在高度断差，局部压力过大，容易出现裂片、崩边风险。
为了解决上述问题，本公开实施例提供了一种调光玻璃及其制造方法，能够降低调光玻璃在安装过程中电连接结构被损坏几率，保证调光功能层正常驱动。
如图1至图4所示，本公开实施例提供的调光玻璃包括：对盒设置的两个玻璃基板100、夹设于两个所述玻璃基板100之间的至少一层调光功能层200及封框胶300，其中，所述玻璃基板100的边缘具有未被所述调光功能层200覆盖的封胶区110，所述调光功能层200至少一侧为绑定侧，所述调光功能层200在所述绑定侧设有绑定电路板210，在所述绑定电路板210上连接有多根导电引线220；所述封框胶300填充于两个所述玻璃基板100的所述封胶区110之间；所述导电引线220包括连接端221、伸出端222、及连接所述连接端221与所述伸出端222的延伸段223，所述连接端221与所述绑定电路板210连接，所述伸出端222延伸出所述玻璃基板100的边缘外侧，所述延伸段223至少一部分沿第一方向X延伸，所述第一方向X为所述调光功能层200的绑定侧边缘的延伸方向，所述延伸段223至少部分位于所述封胶区110内且被所述封框胶300固定。
上述方案中，对夹设于两块玻璃基板100之间的调光功能层200的电连接部分进行了改进，其中将所述绑定电路板210上连接的多根导电引线220 沿所述调光功能层200的绑定侧边缘延伸一段距离后伸出至所述玻璃基板100之外，也就是说，使得导电引线220的连接端221和伸出端222错开一定距离，并通过封框胶300固定导电引线220。这样，当外力拉扯导电引线220的伸出端222时，导电引线220被封框胶300固定，且伸出端222与连接端221之间错开一定距离，相较于相关技术中导电引线220直接从印刷电路板引出的方案来说，封框胶300可对导电引线220起到更好的保护，使得导电引线220不易被拉出，从而，本公开实施例提供的调光玻璃建筑幕墙和采光顶安装过程中，可减少由于导电引线220受到拉扯导致调光功能层200电连接失效的情况；并且，这种结构简单、有效，相较于在玻璃基板100上开槽等方式来说，成本较低，可节省因电连接失效而更换调光玻璃的高昂费用。
这里需要说明的是，所述连接端221可以至少部分或全部位于所述封框胶300所覆盖的区域，即，所述连接端221与所述封框胶300在所述玻璃基板100上的正投影至少部分重合；所述伸出端222延伸至所述玻璃基板100的边缘外侧，其所指的是，所述伸出端222至少部分位于所述封框胶300所覆盖的区域外，即，所述伸出端222至少部分在所述玻璃基板100上的正投影位于所述封框胶外。
需要说明的是，上述方案中，所述延伸段223至少一部分沿第一方向X延伸，其主要目的是使得所述连接端221与所述伸出端222能错开一定距离，所述延伸段223的走线方向大致沿第一方向X延伸，可以是与第一方向X完全一致，也可以是与第一方向X不平行，只要大致沿第一方向X延伸即可。
所述调光功能层200可以包括染料液晶调光层、聚合物分散液晶调光层、电致变色调光层等中的至少一种。所述调光功能层可以包括上、下基板及位于上、下基板之间的染料液晶层或者聚合物分散液晶层或者电致变色层等，其中上、下基板上设置有电驱动结构，例如驱动电极、薄膜晶体管、取向层等，其中上、下基板的衬底可以选用柔性衬底或刚性衬底等任意合适的衬底材料。在所述调光功能层200的绑定侧连接所述绑定电路板210。应当理解的是，对于所述调光功能层200的具体结构不限制。
在一些示例性的实施例中，如图1和图3所示，所述延伸段223铺设于 至少一个所述玻璃基板100的封胶区110上，且在所述封胶区110内固定有至少一个固定结构400，所述延伸段223部分被所述固定结构400固定于所述封胶区110。
采用上述方案，通过所述固定结构400来固定所述导电引线220，并将所述固定结构400固定在所述封胶区110内，这样，可以使得当导电引线220受到拉扯时，其应力可以释放在固定结构400与玻璃基板100的固定位置处，从而导电引线220承受拉扯的应力，不会破坏导电引线220与绑定电路板210的连接位置以及绑定电路板210与调光功能层200连接位置的强度，有效避免了相关技术中采用印刷电路板直接引出导电引线220而导致的电连接方式失效情况，可节省因更换调光玻璃而产生的高额费用。
在一些实施例中，如图2和图4所示，所述固定结构400通过粘接胶500固定在所述玻璃基板100上。该粘接胶500可以选用强力胶，以加强固定结构400的固定强度，这样，所述固定结构400通过所述粘接胶500以及所述封框胶300的固定，可以牢固固定在玻璃基板100上。
当然可以理解的是，以上实施例仅是示例，在其他实施例中，所述固定结构400的固定方式不限于此。
此外，示例性的，所述固定结构400包括固定夹持件，所述固定夹持件包括夹持件主体420，所述夹持件主体420内设有贯通的通道410，所述延伸段223穿设于所述通道410且与所述通道410之间通过固体胶430固定。
采用上述方案，所述导电引线220的延伸段223穿设在所述固定夹持件的通道410内，可在所述夹持件主体420内的通道410中涂覆固体胶430，例如玻璃胶、硅酮胶或树脂胶等，通过固体胶430将所述导电引线220牢固固定在所述固定夹持件上。当然可以理解的是，所述固定结构400的具体结构不限，例如，所述固定结构400也可以是卡扣等其他任意合适的固定结构；此外，所述固定结构400夹持固定导电引线220的方式也不限于采用固体胶430，也可以是通过通道410的内径设计，紧紧夹持住所述导电引线220，实现所述导电引线220的固定。
此外，在一些示例性的实施例中，如图5所示，所述夹持件主体420包括可相互扣合的两个壳体421，两个所述壳体421的一侧通过铰链422铰接， 另一侧通过卡扣组件423连接，每个所述壳体421上设有卡槽411，两个所述壳体421扣合时两个所述卡槽411配合形成所述通道410。
采用上述方案，如图6所示，在组装调光玻璃时，可开启所述卡扣组件423，以使所述夹持件主体420的两个壳体分开(如图6(a)所示)，在卡槽411中A区内涂附固体胶430，然后将导电引线220铺设在涂有固体胶430的卡槽411内(如图6(b)所示)，然后闭合所述卡扣组件，以使两个壳体421扣合(如图6(c)所示)。这样结构简单，组装方便，固体胶430涂覆均匀。当然可以理解的是，以上示例中所述夹持件主体420为分体设置，可打开或闭合，在实际应用中，所述夹持件主体420也可以一体件。
还需要说明的是，上述实施例中，所述夹持件主体420中两个壳体通过一侧铰接一侧卡扣的方式实现开合，在其他未示意的实施例中，所述夹持件主体420中两个壳体也可以是通过其他方式实现开合，例如，两个壳体相对两侧均通过卡扣方式连接等，在此不再一一列举。
此外，所述固定结构400的数量可以是1个或多个。为了进一步加强导电引线220所承受的拉扯力，在一些示例性的实施例中，所述固定结构400的数量为至少两个。当然可以理解的是，在实际应用中，所述固定结构400的具体数量可根据实际应用进行合理选择。
此外，一些示例性的实施例中，所述导电引线220中所述延伸段223沿第一方向X延伸的距离可以在15～20cm之间，所述固定结构400在所述第一方向X上的最大长度可以为1～10cm，示例性的，所述固定结构400在所述第一方向X上的最大长度可以为3～4cm；所述固定结构400在垂直于所述玻璃基板的第二方向上的最大高度为1～25mm，示例性的，在垂直于所述玻璃基板100的第二方向Y上的高度应小于两块玻璃基板100之间的间隙高度，大约为6～8mm；所述固定结构400在垂直于所述第一方向和所述第二方向的第三方向上的最大宽度为1～20mm，示例性的，在垂直于所述第一方向X和所述第二方向Y的第三方向Z上的宽度为8～10mm，所述通道410的内径应满足大于或等于多根所述导电引线220的横截面面积，最大内径约为1～10mm，示例性的，所述通道410的内径大约为3～4mm。
应当理解的是，在实际应用中，对于所述延伸段223的长度、所述固定 结构400的尺寸参数并不进行具体限定，可根据实际需求进行合理选择。
此外，在一些示例性的实施例中，如图1和图3所示，所述延伸段223被配置为：从所述连接端221延伸出之后朝向所述调光功能层200所在一侧弯折，并沿所述第一方向X延伸预定距离后，朝向所述玻璃基板100的外侧弯折并伸出至所述玻璃基板100外。也就是说，所述延伸段223应尽可能地朝内侧(即朝向调光功能层200所在一侧)铺设，这样，当封框胶300固化后会对导电引线220起到更好的保护作用，使导电引线220更不易被拉出。
一些实施例中，所述封框胶300可以选用黑色丁基胶等任意合适的材料制成。所述固定结构400的颜色优选与所述封框胶300的颜色一致。
此外，所述调光功能层200的数量可以是一层或至少两层。图1和图2所示为所述调光功能层200仅有一层的结构示意图。其中，该实施例中，所述绑定电路板210上连接有至少两根所述导电引线220，至少两根所述导电引线220穿过同一所述固定夹持件的所述通道410。这样，可以节约成本，且结构简单，组装方便。
图3和图4所示为所述调光功能层200为两层的结构示意图。该实施例中，所述调光功能层200至少有两层，每一所述调光功能层200的所述绑定电路板210上连接有至少两根所述导电引线220，至少两层所述调光功能层200的多根所述导电引线220穿过同一所述固定夹持件的所述通道410。这样，不同所述调光功能层200的多根导电引线220共用一个固定夹持件，节省所述固定夹持件的数量，降低成本，且组装方便。
需要说明的是，当所述调光功能层200为至少两层时，也可以是同一所述调光功能层200的多根导电引线220共用一个固定夹持件，而不同所述调光功能层200的导电引线220不共用同一固定夹持件。
此外，还需要说明的是，两个所述玻璃基板100中，一个为室内侧玻璃基板100，一个为室外侧玻璃基板100，所述调光功能层200的导电引线220可以通过固定夹持件固定在所述室内侧玻璃基板100上，也可以是通过固定夹持件固定在所述室外侧玻璃基板100上；或者，还可以是，当所述调光功能层200为至少两层时，靠近所述室内侧玻璃基板100的所述调光功能层200对应的导电引线220通过固定夹持件固定在所述室内侧玻璃基板100上，靠 近所述室外侧玻璃基板100的所述调光功能层200对应的导电引线220通过固定夹持件固定在所述室外侧玻璃基板100上。
此外，在相关技术中，绑定电路板210外直接连接印刷电路板，印刷电路板卡扣连接至玻璃基板100上，且印刷电路板上直接引出导电引线220，当导电引线220受到拉扯时，印刷电路板容易松动。而在本公开一些示例性的实施例中，如图所示，所述绑定电路板210包括导电垫片211，所述导电引线220直接焊接于所述导电垫片211上。这样的设计，由于导电引线220可沿第一方向X延伸预定距离、和/或导电引线220通过固定结构400固定，且导电引线220还被封框胶300固定，因此，本公开实施例中可不再设置印刷电路板，而是直接将导电引线220焊接于绑定电路板210的导电垫片上，降低了成本，可适用于各种尺寸的产品，且避免了印刷电路板容易松动的现象。
一些实施例中，如图1和图3所示，在所述导电引线220与所述导电垫片焊接位置包裹有防氧化保护层224，以防止焊接位置氧化。该防氧化保护层224可以选用醋酸布等任意合适的材料。
此外，一种示例性的实施例中，如图1至图4所示，所述调光玻璃还包括支撑框架600，所述支撑框架600位于两个所述玻璃基板100之间，且位于所述调光功能层200的外围，所述封胶区110位于所述支撑框架600的外围。所述支撑框架600可以选用铝框等金属框架。通过所述支撑框架600提高中空钢化结构的强度。其中，固定结构400与支撑框架600之间可不粘接。
本公开实施例另一方面还提供了一种调光玻璃的制造方法，用于制造本公开实施例提供的调光玻璃，所述方法包括如下步骤：
步骤S01、将所述调光功能层200贴合在一个所述玻璃基板100上；
其中，可通过PVB(PolyViny Butyral，聚乙烯醇缩丁醛)胶膜等胶层将所述调光功能层200高温高压贴合在室内侧玻璃基板100表面；
步骤S02、将所述调光功能层200的所述绑定侧的多根导电引线220铺设于所述封胶区110；
其中，所述导电引线220铺设于所述室内侧玻璃基板100表面上；
步骤S03、将另一个所述玻璃基板100放置于所述调光功能层200上， 在两块所述玻璃基板100的所述封胶区110之间填充所述封框胶300，其中所述延伸段223被所述封框胶300固定。
其中，室外侧玻璃基板100可放置在调光功能层200上，并在室内侧玻璃基板100与室外侧基板之间的空隙处打入封框胶300，待封框胶300固化后修齐玻璃基板100外侧多余的封框胶300。
示例性的，所述步骤S02之后，所述方法还包括：步骤S021、通过所述固定结构400固定所述延伸段223，并通过粘接胶500将所述固定结构400固定在所述玻璃基板100上。
具体地，所述步骤S021包括：开启所述固定结构400的两个壳体，并在卡槽中涂附固体胶430(玻璃胶、硅酮胶或树脂胶等)，将导电引线220铺设在涂有固体胶430的卡槽内，并闭合卡扣组件，将闭合后的固定结构400底部涂附强力胶，粘粘在玻璃基板100表面。
以下以图1和图3所示实施例为例，更为详细地说明本公开实施例提供的调光玻璃的制造方法。该方法包括如下步骤：
步骤S01、将导电引线220焊接在所述调光功能层200的绑定电路板210的导电垫片上，使用PVB(PolyVinyl Butyral，聚乙烯醇缩丁醛)胶膜等胶层将调光功能层200(图中Cell1和Cell2)高温高压贴合在室内侧钢化玻璃表面，并使用醋酸布等防氧化层包裹焊接位置防止其氧化；
步骤S02、将导电引线220铺设在室内侧玻璃表面，且至少一段尽量靠近支撑框的一侧铺设；
步骤S021、开启所述固定夹持件的两个壳体，并在卡槽中涂附固体胶430(玻璃胶、硅酮胶或树脂胶等)，将导电引线220铺设在涂有固体胶430的卡槽内，并闭合卡扣组件，将闭合后的固定夹持件底部涂附强力胶，粘粘在玻璃基板100表面；
步骤S03、将室外侧玻璃基板100可放置在调光功能层200上，并在室内侧玻璃基板100与室外侧基板之间的空隙处打入封框胶300，待封框胶300固化后修齐玻璃基板100外侧多余的封框胶300，得到具有调光玻璃。
本公开实施例提供的调光玻璃能够降低调光玻璃在安装过程中电连接结构被损坏几率，保证调光功能层200正常驱动。
本公开对本公开实施例提供的调光玻璃与相关技术中的调光玻璃的导电引线220所承受拉扯应力进行了测试实验。
该测试实验中，本公开提供调光玻璃作为实施例1和实施例2，其中实施例1中采用的固定夹持件数量为2个，实施例2中采用的固定夹持件数量为1个。采用相关技术中的调光玻璃作为对照例。
测试过程如下：
首先，调光玻璃通电，使其内部调光功能层200处于亮态；
然后，将调光玻璃放置地面并固定，使用拉力秤沿垂直地面方向拉扯外部引线，这样可模拟实际安装过程中周边金属型材对调光玻璃的挤压拉扯过程；
然后，用力拉扯外部导电引线220，直至调光玻璃内部调光功能层200失效，其中当透过率突然变小时，则认为内部电连接失效。
测试结果为：
实施例1中的调光玻璃，其导电引线220可承受40Kg以上的拉力，引线受拉扯过程受力点位于固定结构400与玻璃基板100之间的粘合处，当固定结构400被拉坏后，外力才会传递至印刷电路板与导电引线220的焊接位置。
实施例2中的调光玻璃，其导电引线220可承受34Kg以上的拉力，引线受拉扯过程受力点位于固定结构400与玻璃基板100之间的粘合处，当固定结构400被拉坏后，外力才会传递至印刷电路板与导电引线220的焊接位置。
对照例中的调光玻璃，其导电引线220可承受6Kg以上的拉力。
由此可见，本公开实施例提供的调光玻璃中导电引线220的强度提升7倍，实际施工安装调光玻璃时，调光玻璃侧面与金属型材框架之间的摩擦挤压拉扯力约5-15Kg，因此，本公开实施例提供的调光玻璃及其制造方法，能够有效地降低调光玻璃在安装过程中电连接结构被损坏几率，保证调光功能层200正常驱动。
有以下几点需要说明：
(1)本公开实施例附图只涉及到与本公开实施例涉及到的结构，其他结 构可参考通常设计。
(2)为了清晰起见，在用于描述本公开的实施例的附图中，层或区域的厚度被放大或缩小，即这些附图并非按照实际的比例绘制。可以理解，当诸如层、膜、区域或基板之类的元件被称作位于另一元件“上”或“下”时，该元件可以“直接”位于另一元件“上”或“下”或者可以存在中间元件。
(3)在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合以得到新的实施例。
以上，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，本公开的保护范围应以权利要求的保护范围为准。
