Description

Dimming glass and terminal product Technical Field The application belongs to the technical field of electrochromic, and particularly relates to dimming glass and a terminal product. Background Along with the rapid development of new energy automobiles, electrochromic (Electrochromic, abbreviated as EC) devices are gradually applied to automotive awning glass in order to improve the comfort and energy efficiency in the automobiles, so that the awning glass has a dimming function. For aesthetic reasons, the awning glass of new energy automobiles is generally designed to have a high camber and a high curvature. Compared with the traditional glass structure, the flexible electrochromic diaphragm has the characteristics of light weight, cutting performance, bending performance and the like, and can be attached to the surface of curved glass, so that the flexible electrochromic diaphragm is more suitable for forming the awning glass by combining with the curved glass with large curvature. However, in practical applications, flexible EC films often use flexible films such as polyethylene terephthalate (Polyethylene Terephthalate, PET) as a substrate, which are subjected to high temperature and high pressure during the lamination process with glass (i.e., sandwiched between two sheets of glass), especially when sandwiched between two sheets of large-area curved glass with high camber and high curvature, PET films are very prone to wrinkling in stress concentration areas. Such wrinkles not only affect the appearance quality of the dimming glass, but may also cause the electrochromic properties of the dimming glass to be degraded or to be failed. In the prior art, solutions to the problem mainly focus on controlling the hot pressing temperature, the pressure curve or adjusting the thickness of the PET substrate, but the effect is limited, and particularly, the flexible electrochromic film is required to be clamped under the scene of two pieces of curved glass with large curvature, and the generation of wrinkles is still difficult to avoid. Therefore, a new structural design is needed to alleviate the stress applied to the flexible electrochromic film during the lamination process, so as to reduce or avoid the wrinkling of the flexible electrochromic film. Disclosure of utility model In view of the above, the embodiments of the present application provide a light-adjusting glass and a terminal product, so as to solve the technical problem that the existing flexible electrochromic film is easy to generate wrinkles when being combined with curved glass. In a first aspect, an embodiment of the present application provides a light-adjusting glass, including a first curved glass, a first anti-wrinkling layer, a flexible electrochromic film, a second anti-wrinkling layer, and a second curved glass that are sequentially stacked, where the flexible electrochromic film includes a first flexible transparent film, an ion storage layer, an electrochromic layer, an electrolyte layer, and a second flexible transparent film that are sequentially stacked; The first fold-preventing layer and the second fold-preventing layer are respectively and directly contacted with the first curved glass and the second curved glass, or a first sealant layer is arranged between the first fold-preventing layer and the first curved glass, and/or a second sealant layer is arranged between the second fold-preventing layer and the second curved glass. In the prior art, when the flexible electrochromic diaphragm and the curved glass with large curvature are combined to form the dimming glass, the diaphragm is easy to generate folds in a stress concentration area, so that the appearance of the dimming glass is affected, and the electrochromic performance of the dimming glass is reduced or even fails. Based on the principle that the anti-wrinkling layer absorbs deformation of the flexible electrochromic diaphragm generated in the process of combining the flexible electrochromic diaphragm with the curved glass, the wrinkling of the diaphragm is reduced or avoided, the attractiveness of the dimming glass is improved, and the reliability and the light consistency of the dimming glass are guaranteed. Further, when the sealant layer is additionally arranged between the anti-wrinkling layer and the curved glass, the sealant can not only enhance the bonding strength, but also completely fill the interface irregularities before solidification through the fluidity of the sealant, so that the stress uniformity is further improved, and the sealant layer and the anti-wrinkling layer cooperate to prevent the wrinkling of the flexible electrochromic membrane. In some embodiments, the first wrinkle-preventing layer is an optically clear pressure sensitive adhesive layer. In some embodiments, the second anti-wrinkling layer is an optically clear pressure sensitive adhesive layer. The optically transparent pressure-sensitive adhesive layer has the characteristics of high t
