The invention discloses a window assembly mounted on a vehicle-mounted laser radar, which comprises a sapphire substrate on the outer side and an optical glass substrate on the inner side, and is characterized in that a polymer laminated layer made of polyvinyl butyral resin or ethylene-vinyl acetate copolymer is arranged between the sapphire substrate and the optical glass substrate; the sapphire substrate and the optical glass substrate are bonded through the polymer laminated layer to form the window assembly, the thickness of the sapphire substrate is 0.5 mm-1. 5mm, the thickness of the optical glass substrate is greater than 2mm, the thickness of the polymer laminated layer is 0.36 mm-0. 40mm, and the total thickness of the window assembly is less than or equal to 6mm. The window assembly has the advantages that the two substrates made of specific materials are bonded through the specific polymer laminated layer to form the window assembly, and by means of the elastic impact absorption effect of the middle polymer laminated layer, the penetration of an impact object can be effectively prevented, and the cost of the device is greatly reduced.
本发明公开了一种安装在车载激光雷达上的视窗组件,包括外侧的蓝宝石基板和内侧的光学玻璃基板,蓝宝石基板和光学玻璃基板之间设置有由聚乙烯醇缩丁醛树脂或乙烯‑醋酸乙烯共聚物制成的高分子夹胶层,蓝宝石基板和光学玻璃基板通过高分子夹胶层粘接构成视窗组件,蓝宝石基板的厚度为0.5mm~1.5mm,光学玻璃基板的厚度大于2mm,高分子夹胶层的厚度为0.36mm~0.40mm,视窗组件的总厚度小于等于6mm,优点在于由两种特定材料的基板通过特定高分子夹胶层粘接构成视窗组件,借助于中间的高分子夹胶层的弹性吸收冲击的作用,不仅可以有效阻止冲击物的穿透,而且大大降低了器件的成本。
