在本实施方式中，所述通孔140至少部分位于所述信号传输区Q1，即，所述通孔140不仅覆盖所述信号传输区Q1，还可以覆盖所述非信号传输区Q2，探测器200的探测信号透过所述通孔140、所述透波层120和第一透明基板1110进行传输，而不透过所述第二透明基板1120、所述粘结膜1130及所述隔热层130，避免了所述第二透明基板1120、所述粘结膜1130及所述隔热层130对探测信号的阻隔，提高了所述第二透明基板1120、所述粘结膜1130及所述隔热层130的选择自由度，例如所述第二透明基板1120可以选用着色玻璃，所述粘结膜1130可以选用具有隔热性能的粘结膜，所述隔热层130可以选用更高性能的隔热层，使夹层玻璃的产品组合更加丰富多样。
在本实施方式中，所述透波层120设置在所述第二表面1112上，可以通过物理气相沉积法(Physical Vapor Deposition，PVD)或化学汽相沉积法(Chemical Vapor Deposition，CVD)等方法在所述第二表面1112上沉积具有信号高透功能的所述透波层120，提高了所述信号传输区Q1对探测信号的透过率。
在本实施方式中，所述隔热层130设置在所述透波层120靠近所述第二透明基板1120的表面上(如图2)，或者，所述隔热层130设置在所述第三表面1121上(如图3)，或者，所述隔热层130设置在所述粘结膜1130中(如图4)。所述隔热层130可以通过PVD、CVD或溶胶凝胶喷涂等方式直接沉积在所述透波层120靠近所述第二透明基板1120的表面上或所述第三表面1121上。或者，所述隔热层130通过沉积在聚合物薄膜上然后与所述粘结膜1130进行夹层后作为所述粘结膜1130的一部分，如聚对苯二甲酸乙二醇酯(PET)。
对于所述隔热层130在所述夹层玻璃110上的正投影避开所述信号传输区Q1的实现方式。在一种实施方式中，所述隔热层130可以先沉积在所述透波层120靠近所述第二透明基 板1120的表面上或所述第三表面1121上，或者，所述隔热层130通过沉积在聚合物薄膜上然后与所述粘结膜1130进行夹层后作为所述粘结膜1130的一部分。然后再去除所述隔热层130对应所述信号传输区Q1处的部分隔热层130。在另一种实施方式中，先在所述透波层120靠近所述第二透明基板1120的表面上或所述第三表面1121上对应所述信号传输区Q1处覆盖掩膜层，然后再在所述透波层120靠近所述第二透明基板1120的表面上或所述第三表面1121上沉积所述隔热层130，最后再去掉所述掩膜层。或者，先在聚合物薄膜上对应所述信号传输区Q1处覆盖掩膜层，然后再在聚合物薄膜上沉积所述隔热层130，再去掉掩膜层，最后将所述隔热层130与所述粘结膜1130进行夹层。可以实现在保有所述夹层玻璃110的隔热效果的情况下，不会影响所述信号传输区Q1对探测信号的透过率。
在本实施方式中，所述透波层120用于提高所述信号传输区Q1对以55°～70°入射角入射的探测信号的透过率，所述透波层120包含至少一个高折射率层/低折射率层的叠层结构，所述高折射率层的折射率为1.9～2.6，所述低折射率层的折射率为1.3～1.8，通过高折射率层/低折射率层的叠层结构的设计，从而使透过率提高；其中，高折射率层可以具有多个子层，和/或低折射率层也可以具有多个子层，各个子层的材料、厚度、折射率中的至少一项不相同。所述隔热层130用于反射和/或吸收红外线，使夹层玻璃具有较好的隔热效果，所述隔热层130包含至少一个金属银层、银合金层或透明导电氧化物层，所述金属银层、银合金层或透明导电氧化物层具有良好的红外线反射性能，从而减少夹层玻璃对红外线的透过率。所述银合金层的材料优选为银铜合金、银铟合金、银金合金等，所述银合金层中的银含量优选大于或等于95％，更优选大于或等于98％。所述透明导电氧化物层包含至少一个透明导电氧化物层(TCO层)，优选为ITO(掺锡氧化铟)、FTO(掺氟氧化锡)、ATO(掺锑氧化锡)、AZO(掺铝氧化锌)、IZO(掺铟氧化锌)、GZO(掺镓氧化锌)等。所述隔热层130还包含其他介质层。
在相关技术中，为了实现在隔热玻璃上增设能够提高信号透过率的信号传输区，通常通过磁控溅射整面玻璃沉积透波层后，再去除非信号传输区沉积的透波层来实现。或者，通过先在玻璃对应的非信号传输区覆盖掩膜层，再沉积透波层，最后再去除掩膜层来实现。但因为非信号传输区在玻璃上正投影的面积占玻璃所在区域面积的80％以上，所以相关技术为了面积占比很小的信号传输区而去增加除膜工艺，从生产效率和工艺复杂度方面都不理想，导致批量生产过程质量和成本居高不下。
相比于相关技术，就举例而言，具体地(如图2)，在国际标准ISO9050下，所述第一透明基板1110的可见光垂直透过率TL＝89.9％，在所述第二表面1112按顺序连续沉积92nm厚的ZnSnOx、7nm厚的TiOx、117nm厚的SiO2及25nm厚的TiOx形成所述透波层120。接着在所述透波层120靠近所述第二透明基板1120的表面上连续沉积11nm厚的AZO、12.8nm厚的Ag、9nm厚的TiOx、60nm厚的ZnSnOx、20nm厚的AZO、9.2nm厚的Ag、9nm厚的TiOx、8nm厚的AZO、10nm厚的ZnSnOx及10nm厚的Si3N4形成所述隔热层130并在所述隔热层130对应的所述信号传输区Q1处进行除膜。以所述夹层玻璃组件100的车辆1安装角度α＝60°进行试验测试，所述夹层玻璃组件100在所述透波层120和所述隔热层130的重叠区域的可见光垂直透过率TL＝75.6％。所述第四表面1122一侧的可见光在所述夹层玻璃组件100在所述透波层120和所述隔热层130的重叠区域上的反射率RL＝14.1％。所述夹层玻璃组件100在所述透波层120和所述隔热层130的重叠区域的太阳能总透过率TTS＝51.3％。按照国际标准CIE1976，所述夹层玻璃组件100在所述透波层120和所述隔热层130的重叠区域的色差表达公式为L*a*b＝43.8*-1.8*-9.8，呈现淡蓝色外观。所述信号传输区Q1对以60°入射角入射的波长为905nm的探测信号的透过率Ts1＝87.04％，相比于没有沉积所述透波层 120的信号传输区Q1对以60°入射角入射的波长为905nm的探测信号的透过率Ts2＝81.5％提高了5.54％。通过试验测试可以得出，本实施方式中所述隔热层130的设置可以有效地进行隔热，所述透波层120的设置可以有效地增加所述信号在所述信号传输区Q1的透过率，且所述隔热层130与所述透波层120的重叠设置还能够提供能够让人眼感到舒适的颜色外观，例如淡蓝色等。
在本实施方式中(如图2)，仅需要对所述隔热层130在对应的所述信号传输区Q1处进行除膜，且无需对所述透波层120在对应所述非信号传输区Q2处进行除膜，从而使得制造工艺更简单，因此本申请夹层玻璃组件100兼容隔热和局部红外高透功能且制造效率高。同时，在本实施方式中，所述透波层120可部分作为所述隔热层130的基底，在所述夹层玻璃组件100加工成型过程中，所述透波层120可以有效阻挡所述第一透明基板1110中碱金属离子游离至所述隔热层130中，无需另外增加基底膜层对所述隔热层进行保护，就能够保证所述隔热层130在夹层玻璃组件100的制造工艺中隔热功能不会受损，进一步还能够起到调节颜色的作用。所述透波层120与所述隔热层130在所述第二表面1112上顺序连续沉积的工艺高效简单，使得所述夹层玻璃组件100兼容隔热和局部红外高透功能且制造效率高。
