Document Type and Number:
WIPO Patent Application WO/2024/017364
Kind Code:
A1
Abstract:
Disclosed in the present invention are switchable transparent glass, a vehicle door assembly, and a vehicle. The switchable transparent glass comprises: two glass plates (1); at least one switchable transparent film (3) provided with a plurality of edge portions (31); at least two adhesive layers (2) sandwiched between the two glass plates (1), each adhesive layer (2) comprising a light-transmitting portion (22) and at least one light-shielding portion (23) which are connected to each other, and the switchable transparent film (3) being sandwiched between the light-transmitting portions (22) of the two adhesive layers (2); and a protective layer (4) spliced with the plurality of edge portions (31) of the switchable transparent film (3) and sandwiched between the two adhesive layers (2), wherein at least one edge portion (31) of the switchable transparent film (3) is a visual edge portion (311), and the splicing position of the visual edge portion (311) and the protective layer (4) is sandwiched between the light-shielding portions (23) of the two adhesive layers (2). The present invention can effectively avoid the shortening of service life caused by the degradation of the edge portions (31) of the switchable transparent film (3), and uses the light-shielding portion (23) to shield the splicing position of the visual edge portion (311) of the switchable transparent film (3) and the protective layer (4) so as to prevent a bright joint at the splicing position of the visual edge portion (311) and the protective layer (4) from affecting visual experience when the switchable transparent glass is observed.
