[0002] Currently, the automotive industry is developing rapidly, especially new energy vehicle manufacturers. There is an endless stream of various traditional rearview mirror lenses and electronic rearview mirrors, with diverse structures. Restricted by various technologies, their structures are relatively complex. Electronic rearview mirrors are usually made by sandwiching a liquid layer between two pieces of glass. This method is costly in terms of materials and manufacturing processes, has extremely high requirements for the consistency of the two pieces of glass, and there is also a phenomenon of uneven color change, posing certain safety risks. Therefore, in actual production, there are high requirements for the working efficiency and stability of the manufacturing process, and there are many difficulties in production and manufacturing. Summary of the Utility Model

[0006] By adopting the above technical solutions, the traditional form of sandwiching a liquid layer between two pieces of glass is changed to coating a single piece of glass. Replacing two pieces of glass with a single piece of glass forms a feasible solution, effectively reducing the complexity during processing while ensuring normal use, eliminating the requirements for the process precision of the two pieces of glass, and replacing the original liquid functional layer and conductive layer with film layers, which facilitates the production and processing of electronic rearview mirror lenses and improves product stability.

[0015] Preferably, the functional film layer includes an electrochromic film layer.

[0016] By adopting the above technical solution, through the setting of the electrochromic film layer, electrochromism is realized to absorb strong light and prevent glare, solving the problem of glare and dazzling caused by strong light reflection when the driver observes the rearview mirror when there is a vehicle coming from behind, and reducing the occurrence of traffic accidents.

[0021] Preferably, the functional film layer includes a protective film layer.

[0022] By adopting the above technical solution, through the setting of the protective film layer, the rest of the film layers are protected, and the interference of the external environment on the functional film layer and the conductive film layer is reduced.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Through the setting of the lens glass, the conductive film layer, and the functional film layer, the traditional form of double-piece glass sandwich is changed to the design of single-piece glass coating, canceling the original requirement for the process precision of two pieces of glass, and replacing the original liquid functional layer and conductive layer with solid film layers, which is convenient for the production and processing of electronic rearview mirror lenses and improves the product stability;

[0025] 2. By providing the first conductive film, the second conductive film, the barrier film layer, and the electrochromic film layer, the film layer can be externally connected to a circuit and the electrochromic film layer can change color when powered on. After the electrochromic film layer changes color when powered on, it absorbs strong light to prevent glare, solving the problem of glare caused by strong light reflection when the driver observes the rearview mirror when there is a following vehicle, and reducing the occurrence of traffic accidents.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following will further describe the present application in detail Figure 1 with reference to the accompanying drawings.

[0029] The embodiment of the present application discloses an electronically anti-glare automotive rearview mirror lens with a single-piece multi-layer film.

[0030] As Figure 1 shown, an electronically anti-glare automotive rearview mirror lens with a single-piece multi-layer film includes a lens glass 1. The lens glass 1 can be any one of flat glass, curved glass, and multi-curved glass, and different glass forms can meet different actual usage requirements.

[0031] As Figure 1As shown in the figure, a conductive film layer 2, a functional film layer 3, and a reflective film layer 4 are deposited on the lens glass 1 by sputtering. The coating layer materials include chromium, titanium, tungsten, aluminum, silver, nickel, silicon, tantalum, tin, niobium, indium, tin, etc. The corresponding materials are used according to the actual functions. Among them, the conductive film layer 2 includes a first conductive film 21 and a second conductive film 22 arranged at intervals. In this embodiment, it is preferably that both the first conductive film 21 and the second conductive film 22 are transparent conductive films made of ITO materials. The functional film layer 3 includes an electrochromic film layer 31, a barrier film layer 32, and a protective film layer 33. In this embodiment, it is preferably that the barrier film layer 32 is an ion-conducting layer made of silicon oxide material, and the protective film layer 33 is a protective film made of silicon dioxide material. The reflective film layer 4 is a reflective film made of chromium material. In actual use, a first conductive film 21, an electrochromic film layer 31, a barrier film layer 32, an electrochromic film layer 31, a second conductive film 22, a reflective film layer 4, and a protective film layer 33 are sequentially formed on the lens glass 1, forming a multi-layer coating structure. Among them, the electrochromic film layer 31 has two layers, and the lead electrodes are used to connect to an external power supply. The electrochromic film layers 31 on both sides of the barrier film layer 32 are a color-changing layer 311 made of tungsten oxide and Li and an ion storage layer 312 made of nickel tungsten oxide, respectively. Specifically, when a negative voltage is applied to the color-changing layer 311 during use, protons are injected into the color-changing layer 311, and the color-changing layer 311 becomes dark blue. When a positive voltage is applied to the color-changing layer 311, protons escape from the color-changing layer 311 and enter the ion storage layer 312 through the barrier film layer 32, making the color-changing layer 311 become light-colored.

[0032] It should be understood that the above multi-layer coating layer can be formed on the lens glass 1 with different shapes. When the lens glass 1 is a curved glass, the curved glass will have a concave surface or a convex surface. The multi-layer coating layer can be formed on the concave surface of the lens glass 1 or on the convex surface of the lens glass 1. When the lens glass 1 is a multi-curved glass, the multi-curved glass will have a concave surface and a convex surface. The multi-layer coating layer can be formed on the concave surface and the convex surface of the lens glass 1, and is not restricted by the shape of the lens glass 1. And no matter what form it is, when in use, the lens glass 1 needs to face the user, and the coating layer is used at the end far from the user.

[0033] The implementation principle of the embodiment of this application is as follows: When put into actual use, the lens is installed on the rearview mirror of the car, and the lens glass 1 faces the user. When the external light is strong, the external circuit is connected. After being powered on, the ions between the multi-layer coating layers move, and moving into the electrochromic film layer 31 can make the color of the electrochromic film layer 31 deepen, solving the problem of strong light reflection and glare when the driver observes the rearview mirror when there is a vehicle coming from behind, reducing the occurrence of traffic accidents, and being applicable to all interior and exterior rearview mirrors and other auxiliary mirrors of the car. And in the form of a coating layer, it is convenient for production and processing, and improves the stability of the processed products.

[0034] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
