The invention provides electric heating glass and a vehicle window assembly. The electric heating glass comprises laminated glass and a heating element, and the laminated glass is provided with a sensor visual field area and a windscreen wiper stop area. The heating power density E1 of the first sub-heating element in a sensor view area is 450 W/m < 2 > to 1800 W/m < 2 >, the heating power density E2 of the second sub-heating element in a windscreen wiper staying area is 450 W/m < 2 > to 1800 W/m < 2 >, and the diameter of the first sub-heating element is not equal to that of the second sub-heating element. According to the electric heating glass and the vehicle window assembly provided by the invention, the heating element is used for quickly removing fog, frost, snow and ice; the diameter and the heating power density of the heating element are limited, so that the heating precision and the energy utilization rate are improved; in addition, the sensor view area and the windscreen wiper staying area can be independently heated or heated at the same time, the heating requirements of different scenes are met, and the heating effect of the electric heating glass is improved.
本申请提供了电加热玻璃及车窗总成。电加热玻璃包括夹层玻璃、及加热元件,夹层玻璃具有传感器视野区以及雨刮停留区。第一子加热元件在传感器视野区的加热功率密度E1为450W/m2~1800W/m2,第二子加热元件在雨刮停留区的加热功率密度E2为450W/m2~1800W/m2,第一子加热元件的直径不等于第二子加热元件的直径。本申请提供的电加热玻璃及车窗总成,利用加热元件实现快速除雾除霜除雪除冰;本申请还通过限定加热元件的直径与加热功率密度,从而提高加热的精准度以及能源利用率;本申请还能够实现传感器视野区和雨刮停留区各自独立加热或同时加热,满足不同场景的加热需求,提高电加热玻璃的加热效果。
