Title:
VEHICLE WINDOW ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2023/280200
Kind Code:
A1
Abstract:
The present application provides a vehicle window assembly. The vehicle window assembly comprises a first carrying plate, a first conductive layer, a second conductive layer, a first bus bar, and a second bus bar. The first bus bar is in direct electrical contact with the first conductive layer. The second bus bar is in direct electrical contact with the first conductive layer or the second conductive layer. The vehicle window assembly is provided with directly connected first heating region and second heating region between the first bus bar and the second bus bar. The first conductive layer at least covers the first heating region. The second conductive layer at least partially covers the second heating region. The total resistance of the first heating region is greater than the total resistance of the second heating region. The sheet resistance of the first heating region is greater than the sheet resistance of the second heating region. The present application achieves simultaneous heating of a main viewing region of the vehicle window and a wiper parking region, to reduce or even eliminate local hot spots possibly generated in the wiper parking region, and simultaneously ensure that at least the heating temperature rise in the main viewing region satisfies a requirement of being greater than or equal to 6°C within 4 minutes.
