Title:
VEHICLE WINDOW GLASS, MANUFACTURING METHOD THEREFOR, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/078605
Kind Code:
A1
Abstract:
Provided in the present application are a vehicle window glass, a manufacturing method therefor, and a vehicle. The vehicle window glass comprises a glass substrate and a transparent nanofilm, the glass substrate comprising an outer surface and an inner surface which are oppositely arranged, and the transparent nanofilm being arranged on the inner surface. The transparent nanofilm comprises a standard high-refractive-index layer, an enhanced high-refractive-index layer and an outermost low-refractive-index layer. In the direction away from the inner surface, the standard high-refractive-index layer, the enhanced high-refractive-index layer and the outermost low-refractive-index layer are successively stacked, the refractive index of the standard high-refractive-index layer being 1.61-2.59, the refractive index of the enhanced high-refractive-index layer being greater than or equal to 2.6, and the refractive index of the outermost low-refractive-index layer being 1.35-1.60. The technical solutions provided by the present application can meet the transmissivity requirement of LiDAR signals and the reflectivity requirement of head-up display systems at the same time.
