Description

具有可电控的光学性能的复合玻璃板
本发明涉及具有可电控的光学性能的复合玻璃板，以及包括这种复合玻璃板的复合玻璃板装置，以及制造这种复合玻璃板的方法。本发明还涉及具有这种复合玻璃板和复合玻璃板装置的运载工具，特别是道路运载工具。
长期以来，具有可电控的光学性能的光电功能元件以各种形式已知，并用于工业批量生产，例如电视机、笔记本电脑、移动电话/智能手机和平板电脑中。
具有可电控的功能元件的复合玻璃板也是本身已知的。功能元件的光学性能可以通过施加的电压来改变。这种功能元件的实例是PDLC（聚合物分散液晶）功能元件，其例如由DE 102008026339 A1已知。在此，活性层包含嵌入聚合物基质中的液晶。如果不施加电压，则液晶以无序的形式取向，这导致穿过活性层的光的强烈散射。如果将电压施加到平面电极上，则液晶沿共同方向取向，并且使穿过活性层的光的透射增加。
已经提出了挡风玻璃板以及玻璃顶，在其中通过这种功能元件实现了可电控的遮阳板，以代替机动车中的常规机械可折叠遮阳板。例如从DE 102013001334 A1、DE102005049081 B3、DE 102005007427 A1和DE 102007027296 A1中已知具有可电控的遮阳板的挡风玻璃板。
所谓的平视显示器也已经是多年以来已知的，其用于为载人轿车的驾驶员将特别重要的信息（例如速度限制、导航提示、当前车速等）直接显示在他的视野中。应理解的是，这种光电显示元件具有结构化的控制电极并且与相应更复杂的控制单元共同作用。
SPD（悬浮颗粒装置）、PNLC（聚合物网络液晶）和PDLC功能元件作为多层膜是可商购的，其中，活性层和施加电压所需的平面电极布置在两个通常由PET制成的载体膜之间。在复合玻璃板的制造过程中，从提供的多层膜裁剪出所需尺寸和形状的功能元件，并***到用于将两个玻璃板层压在一起以形成复合玻璃板的中间层的膜之间。
此外，已知的是，对具有装入的光电功能元件的复合玻璃板配备操纵工具，该操纵工具可以用于实施手动的接通或断开或者其它手动操纵。这样的操纵工具通常位于仪表板上或前玻璃板的上边缘处且邻接车顶的操纵单元上。操纵工具的这种安置使得直观操作变困难并且分别地在一方面要求特定前玻璃板类型与装入的具有不同结构或不同配置的功能元件之间的匹配，并且要求仪表板或玻璃板上边缘处的操作单元的具体实施形式。
WO 2019/086653 A1公开了具有光电功能元件的复合玻璃板，该光电功能元件布置在两个中间层之间。该光电功能元件可以由布置在功能元件区域中的电容式切换区控制。在此，没有给出关于电容式切换区的设计和层堆叠体中的布置的提示。
因此，本发明的基本目的是提供具有集成的光电功能元件的改进的复合玻璃板，其特别是使得功能元件的直观操纵变容易，并且基本上不需要使运载工具装备的其它部件与前玻璃板的特定配置相匹配。本发明的目的还是提供制造这种复合玻璃板的改进的简单方法。
本发明的目的在产品方面通过根据独立权利要求1的复合玻璃板来实现。在其装置或***方面，所述目的通过具有权利要求12的特征的复合玻璃板装置来实现。优选的实施方式由各个从属权利要求得知。
本发明的复合玻璃板包括至少一个外玻璃板和内玻璃板，它们通过热塑性中间层彼此接合。该复合玻璃板被设置用于在例如运载工具、建筑物或房间的窗户开口中将内部空间与外部环境隔开。在本发明的上下文中，内玻璃板是指朝向内部空间的玻璃板。外玻璃板是指朝向外部环境的玻璃板。中间层用于将这两个玻璃板接合，如在复合玻璃板中常见的那样。
外玻璃板和内玻璃板优选由玻璃制成。但是原则上，它们也可以由塑料构成。外玻璃板和内玻璃板的厚度可以在很大的范围内变化，并因此适应各种情况的要求。外玻璃板和内玻璃板的厚度优选为0.4mm至3.5mm，特别优选1mm至2.5mm。玻璃板可以是清澈的，或也可以是有色或着色的。当将该复合玻璃板用作载人轿车中的挡风玻璃板时，必须注意，挡风玻璃板在中央视区中具有足够的透光率，优选在根据ECE-R43的主透视区A中至少70％。
此外，本发明还可以用于各种运载工具，尤其是载人轿车，以及例如小船/轮船或公共汽车的顶玻璃（“遮阳篷”）。技术细节基本上对应于上面和下面描述的本发明的方面。外玻璃板、内玻璃板和/或中间层可以具有其它合适的本身已知的涂层，例如抗反射涂层、抗粘涂层、抗刮擦涂层、光催化涂层或防晒涂层或所谓的低辐射涂层。
本发明的复合玻璃板包括具有可电控的光学性能的光电功能元件，其嵌入中间层中。该功能元件布置在中间层的至少两个热塑性材料层之间，其中，该功能元件通过第一层与外玻璃板接合并且通过第二层与内玻璃板接合。
所述功能元件包括至少一个活性层，该活性层布置在第一载体膜和第二载体膜之间。所述活性层具有可变的光学性能，其可以通过施加到活性层上的电压来控制。在本发明的上下文中，可电控的光学性能被理解为是指可无级控制的那些性能，但同样也被理解为是指可在两个或更多个离散状态之间切换的那些性能。所述光学性能尤其涉及透光率和/或散射行为。该功能元件还包括用于将电压施加到活性层上的平面电极，其优选布置在载体膜和活性层之间。第一载体膜布置在活性层的指向外玻璃板方向的那面上，且第二载体膜布置在活性层的指向内玻璃板方向的那面上。
在一个优选实施方式中，功能元件是PDLC功能元件。PDLC功能元件的活性层包含嵌入聚合物基质中的液晶。在另一个实施方式中，功能元件是SPD功能元件。在此，活性层包含悬浮颗粒，其中，可以借助于施加到平面电极上的电压来改变活性层对光的吸收。然而，原则上也可以使用其它类型的可控功能元件，例如电致变色功能元件。这种可控功能元件及其工作方式本身是本领域技术人员已知的，因此在这一点上可以省去详细的描述。
通常，平面电极和活性层被布置为基本上平行于外玻璃板和内玻璃板的表面。平面电极以本身已知的方式与外部电压源电连接。电触点如同与对活性层进行调温的能量源的接头那样是通过合适的连接电缆，例如箔导体来实现的，其任选地通过所谓的汇流排（母线），例如导电材料条或导电印刷物而与平面电极连接。功能元件的厚度为例如0.1mm至1mm。
优选将平面电极设计为透明导电层。所述平面电极优选包含至少一种金属、金属合金或透明导电氧化物（透明导电氧化物，TCO）。平面电极可以包含例如银、金、铜、镍、铬、钨、氧化铟锡（ITO）、掺杂镓或掺杂铝的氧化锌和/或掺杂氟或掺杂锑的氧化锡。平面电极的厚度优选为10nm至2μm，特别优选20nm至1μm，非常特别优选30nm至500nm。
功能元件特别是作为具有两个外部载体膜的多层膜存在。在这种多层膜中，平面电极和活性层通常布置在两个载体膜之间。在此，外部载体膜是指所述载体膜形成多层膜的两个表面。因此，功能元件可以作为层压膜提供，其可以被有利地加工。由于载体膜，功能元件被有利地保护而不受损害，特别是腐蚀。
本发明包括这样的想法，即局部集成到复合玻璃板中的功能元件的操纵以理想的直观形式直接实现在功能元件的安装位置处或直接在复合玻璃板上至少在其紧邻附近。本发明还包括这样的想法，即为此将具有适合于这一目的的电容式触摸功能的切换元件集成到复合玻璃板内部中。
特别地，所述光电功能元件设置在复合玻璃板的第一子区域中，并且触摸切换元件安置在复合玻璃板的第二子区域中，该第二子区域包含在第一子区域中。
该触摸切换元件布置在光电功能元件的活性层和热塑性中间层之间。在此，触摸切换元件布置在活性层的指向内玻璃板方向的那侧上，从而在从内部空间操作时确保电容式触摸切换元件的功能。所述热塑性中间层优选地包括朝向外玻璃板的第一热塑性材料层和朝向内玻璃板的第二热塑性材料层。在这种情况下，触摸切换元件布置在第二热塑性材料层和活性层之间。该电容式触摸切换元件优选地布置为与第二载体膜直接接触。如果触摸切换元件直接安装在第二载体膜上，则该触摸切换元件因此可以作为包括光电功能元件的多层膜的一部分被引入复合玻璃板中。这提供的优点是，没有其它单独的具有接触切换元件的膜片集成在复合玻璃板中，这些膜片例如可能导致玻璃板的厚度变化。
在第一实施变体中，这可以这样进行，即触摸切换元件具有结构化的导电层，该结构化的导电层布置在光电功能元件的分配给内玻璃板的表面上。因此，在触摸切换元件的区域中布置了结构化的导电层。在此，该结构化的导电层可以通过例如粘贴已准备好的导体结构或通过印刷而施加到第二载体膜上。该变体优选看起来如下：结构化的导电层具有触摸切换结构，该触摸切换结构通过对导电层进行激光结构化而形成，其中，该导电层在基于真空的涂覆方法中沉积。合适的基于真空的涂覆方法是例如CVD（化学气相沉积）或PVD（物理气相沉积）。
该变体特别适合于这样的应用，即在其中应生产具有可商购的PDLC复合膜或其它以标准方式预制的中间层层压体且具有集成的功能元件的本发明复合玻璃板。为了实现本发明，此时仅需要对所提供的层压体的表面或内玻璃板的朝向中间层的那面在合适的位置处设置触摸切换元件（和馈线）。
在本发明的一个替代实施方式中，触摸切换元件由光电功能元件的朝向内玻璃板的平面控制电极的专用触摸切换结构形成。该实施方式适用于这样的应用，即在其中可以从一开始在考虑到本发明的功能的情况下设计光电功能元件的控制电极结构，并然后相应地制造。相应地，其需要根据本发明配置中间层层压体，但能够对此省去如在上述实施变体中所要求那样的后处理步骤。触摸切换结构特别优选地通过对朝向内玻璃板的平面控制电极进行激光结构化来产生。这可以通过对包括光电功能元件的可商购复合膜进行激光处理来完成。激光结构化可以灵活地适应于各自的安装情况，从而可以在平面中容易地改变触摸切换元件的位置和形状。
通过适当的标记，例如通过在触摸切换元件处或其周围设置黑色印刷物，可以使得用户容易从视觉上识别触摸切换元件的位置。这样的黑色印刷物本来已例如设置在载人轿车挡风玻璃板或遮阳篷中在其边缘区域中，因此触摸区元件的相应标记几乎不需要额外的技术支出并且不使玻璃板变昂贵。
在一个适合于简单切换功能的配置中，触摸切换元件具有两个平行或同心的导体，所述导体具有以0.3至1.5cm，特别是0.5至1cm的彼此距离布置的触摸切换部分。为了可靠地实现切换功能，所述导体间距可借助于成年人的手指或拇指来安排，并且任选也可以处于这里提到的范围之外。
为了更复杂的控制功能，触摸切换元件优选地具有大量彼此隔开的且向着光电功能元件外部单独连接或可连接的导体。在这种配置中，可以尤其使用从智能手机和类似设备已知的“轻扫”通过切换元件或有针对性地触摸其子区域从多个可用设定中选择特定设定。
本发明的复合玻璃板装置除了上面阐述的复合玻璃板之外还包括用于控制光电功能元件的光学性能的控制单元和与该触摸切换元件连接的用于切换的切换控制单元，该切换控制单元用于手动控制该光电功能元件，特别是用于接通/断开或用于对比度或亮度设定等。
在适合于超越简单的接通/断开的控制操作的配置中，所述切换控制单元具有与所述触摸切换元件的可单独连接的导体的数量相对应的输入端数量。响应于各自信号输入端处的信号接收，它激活所述光电功能元件的多于两个控制状态之一。
本发明的另一方面是制造本发明复合玻璃板的方法。
对包括层堆叠体的光电功能元件配备电容式触摸切换元件，该堆叠体按所示顺序包括第一载体膜、透明平面控制电极、活性层、透明平面控制电极和第二载体膜。然后通过热塑性中间层将该光电功能元件层压在外玻璃板和内玻璃板之间。
因此，该方法能够通过简单的层压方法来简单地制造具有电容式触摸切换元件的包括光电功能元件的复合玻璃板。由于触摸传感器所需的结构已经被集成到具有光电功能元件的多层膜中，因此在层压时仅需要集成这一附加部件和使其取向并且对其配备电接头。与常规制造相比，这大大简化了制造方法，在常规制造中对于触摸切换元件而言分别需要单独的部件。另外，避免了由于附加***的具有接触切换元件的单独模所致的材料不兼容。
没有电容式触摸切换元件的层堆叠体是可商购的。现在优选地通过在第二载体膜的表面上印刷或粘贴结构化的导电层而对该层堆叠体配备电容式触摸切换元件。替代地且优选地，在第二载体膜的暴露表面上优选通过CVD或PVD方法将导电层沉积在至少电容式触摸切换元件的区域中。然后可以用激光而使该导电层结构化，从而产生触摸切换结构。
替代地且优选地，通过对邻接第二载体膜的平面控制电极进行激光结构化来产生电容式触摸切换元件。在此，使激光聚焦在具有平面控制电极的层上，而不损坏位于其上的载体膜。在此产生了电绝缘区域，该电绝缘区域将各个导体带彼此分开。
参考附图和实施例更详细地解释本发明。所述图是示意图，并非按真实比例。附图不以任何形式限制本发明。其中：
图1示出了作为具有可电控的遮阳板的挡风玻璃板的本发明复合玻璃板的第一实施方式的俯视图，
图2示出了图1的挡风玻璃板的截面，
图3示出了图2的区域Z的放大图，
图4示出了本发明复合玻璃板的一个实施方案的示意性透视图，
图5示出了本发明复合玻璃板中的触摸切换元件的一个替代实施方式的示意图，以及
图6以功能框图的形式示出了本发明复合玻璃板装置的一个实施方案的示意图。
图1、2和3分别示出了具有可电控的遮阳板S的挡风玻璃板W的细节，该挡风玻璃板是本发明的具有可电控光学性能的复合玻璃板的一个示例性实施方式。挡风玻璃板W包括外玻璃板1和内玻璃板2，它们通过中间层3彼此接合。外玻璃板1的厚度为2.1mm，并由绿色着色的钠钙玻璃构成。内玻璃板2的厚度为1.6mm，并由清澈的钠钙玻璃构成。该挡风玻璃板具有在安装位置中朝向顶部的上边缘D和在安装位置中朝向发动机室的下边缘M。
所述挡风玻璃板在中央视区B（如ECE-R43中定义）上方的区域中配备有可电控的遮阳板S。在遮阳板S的上部边缘区域中设置了触摸切换元件T，其用于接通/断开遮阳板功能，并且任选地（取决于具体的实施方式）还用于手动设定遮阳板的透射率。
遮阳板S由作为功能元件4的可商购的PDLC多层膜形成，该PDLC多层膜嵌入中间层3中。中间层3包括总共三个热塑性层3a、3b、3c，它们分别由PVB制成的厚度为0.38mm的热塑性膜形成。第一热塑性层3a与外玻璃板1接合，第二热塑性层3b与内玻璃板2接合。位于其间的第三热塑性层3c具有切口，在该切口中，所裁剪的PDLC多层膜基本上精确配合地，即在所有侧面上大致齐平地***。也就是说，第三热塑性层3c似乎形成了用于约0.4mm厚的功能元件4的一种框，该功能元件因此在周围被包封在热塑性材料中并因此受到保护。
第一热塑性层3a具有有色区域3a'，该有色区域布置在功能元件4和外玻璃板1之间。由此，在遮阳板4的区域内附加地降低了挡风玻璃板的透光率，并且PDLC功能元件4在漫射状态下的乳状外观被减轻。该挡风玻璃板的美观性由此被设计为明显更吸引人。
可控的功能元件4是多层膜，其由在两个平面电极8、9和两个载体膜6、7之间的活性层5构成。活性层5包含其中分散有液晶的聚合物基质，该液晶根据施加到平面电极上的电压而取向，从而可以调节光学性能。载体膜6、7由PET构成并且具有例如0.125mm的厚度。
载体膜6、7在朝向活性层5的表面上设有厚度约为100nm的由ITO制成的涂层，其形成平面电极8、9。平面电极8、9可以经由未示出的汇流排（例如由含银的丝网印刷物形成）和同样未示出的连接电缆而与车载电网连接。为了实施本发明，朝向挡风玻璃板W的内玻璃板2的平面电极9可以在小的子区域中设有通过激光处理而产生的导体结构，由该导体结构形成触摸切换元件T（图1），并且一方面与用于实现遮阳板功能的大面积ITO涂层和另一方面与车载电网连接。
所述挡风玻璃板如常见那样具有环绕的外周覆盖印刷物10，其由不透明的搪瓷在外玻璃板1和内玻璃板2的内侧表面（在安装位置中朝向运载工具的内部空间）上形成。功能元件4与挡风玻璃板的上边缘D和侧边缘的距离小于覆盖印刷物10的宽度，因此功能元件4的侧边缘（除了指向中央视野B的侧边缘外）被覆盖印刷物10覆盖。未示出的电接头也适宜地安装在覆盖印刷物10的区域中并因此被隐藏。触摸切换元件T也可以安置在覆盖印刷物的区域中，更确切地说特别是当它由不透明的导体结构形成时（对此参见下文）。
图4示出了挡风玻璃板W的一个示例性实施形式，其具有图2所示的结构并且具有触摸区元件的特定配置。挡风玻璃板的部件由在图2中也使用的附图标记标示，并且触摸切换元件在此具有附图标记11。
如图可见，触摸区元件11包括两个同心圆形导体11a、11b，它们与用于触摸切换元件的外部接头的专用连接件13（例如以MQS（微型quadlock***）插头的形式）连接。连接件13布置在光电功能元件4的与母线14a、14b不同的侧边缘上，所述母线将功能元件与（在此未示出的）外部控制电路连接。如上所述，具有导体11a、11b的接触切换元件11可以在使用已知的技术和激光束处理装置的情况下通过对光电功能元件4的透明平面元件8、9之一进行激光结构化来形成。
图5a示出了穿过具有触摸切换元件11的区域的截面，该触摸切换元件通过对功能元件4的平面电极9进行激光结构化来产生。电绝缘区域17通过激光处理来产生。图5b示出了触摸切换元件11的替代实施方式，在其中在光电功能元件4上产生了单独的导电层12。在此，触摸切换元件11通过对附加的导电层12进行结构化而形成，而功能元件4的平面电极8、9在此仅用于实现其其它功能。
该实施方式能够使用独立于触摸切换功能而配置的中间层层压体，并且随后将触摸切换功能实现为功能元件4的一部分。
图5b所示的结构的变体中，原则上也可以在挡风玻璃板的内玻璃板的朝向功能元件4的内表面上设置导电层12。附加的导电层12例如可以通过本身已知的印刷方法或也可以通过溅射来形成。
图6示意性地示出了复合玻璃板装置，其包括根据本发明设计的挡风玻璃板W以及（未示出的）运载工具中的相关控制装置。
光电功能元件4布置在挡风玻璃板W的子区域中，相反，触摸切换元件11设置在功能元件4的表面的子区域中。如已在图5中所示，为了连接功能元件4，两个母线14a、14b以本身已知的方式布置在其第一侧边缘处，并且将特定的连接件13分配给触摸切换元件11，该连接件安置在功能元件的另一个侧边缘上。代替母线14a、14b以及上面指明为MQS插头的连接件13，基本上也可以使用其它类型的连接件，只要它们适合用于在此讨论类型的复合玻璃板中或与其一起使用。
功能元件4以本身已知的方式由控制单元15控制以实现其常见功能，而触摸切换元件11经由连接件13与切换控制单元16连接，该切换控制单元例如由于驾驶员的手动操纵而控制功能元件4或任选其子区段的接通或断开状态或此外功能元件4的特定参数。在此，这例如可以是透射率或对比度或亮度或其它参数，其通过运载工具的驾驶员根据环境条件或根据他的喜好进行的个性化设定是有意义或希望的。
在该图中，控制单元15和切换控制单元16的功能的联接仅通过简单的信号连接示意地图示；然而，这两个单元的共同作用可被设计为更复杂的，并且这两个单元15、16也可以彼此集成。
本发明的实施方式整体上不限于以上强调的方面和上述实施例，而是以所附权利要求的范围内的大量变体的形式同样可行的。
