Abstract

The invention belongs to the technical field of automobile glass, and discloses an intelligent automobile glass. The intelligent automobile glass comprises a first laminated glass layer, a hollow layer and a second laminated glass layer, the hollow layer is composed of a cavity formed by the first laminated glass layer, a spacer and the second laminated glass layer and gas filled in the cavity, and the spacer, the first laminated glass layer and the second laminated glass layer are bonded and sealed through sealant; a transparent graphene electrothermal film is arranged on the side surface, close to the hollow layer, of the first laminated glass layer; and a photochromic film is arranged on the upper portion of the face, close to the hollow layer, of the second laminated glass layer, and an antireflection film is arranged on the lower portion of the other face of the second laminated glass layer. The automobile glass has good visible light permeability, heat insulation, sound insulation, noise reduction and anti-condensation performance, can intelligently adjust light rays and perform electric heating defrosting, is safe and energy-saving, effectively prevents glass reflection virtual images, is particularly suitable for new energy automobile front windshields, and has wide market prospects.
