Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electrochromic devices, in particular to an electrochromic packaging structure of a car rearview mirror. Background Art
[0002] Rearview mirrors are a crucial component in automobiles, allowing drivers to observe the environment behind, to the sides, and below the vehicle while driving, thus expanding their field of vision. However, when driving at night, traditional rearview mirrors are often glared by the headlights of following vehicles, and the reflected light from the mirrors can enter the driver's eyes, causing glare and compromising driving safety. Electrochromic rearview mirrors, on the other hand, effectively address this safety hazard by absorbing most of the incoming light, reducing the reflectivity of the mirror to approximately 10%.
[0003] Traditional electrochromic rearview mirrors are made of a glass substrate that encapsulates an electrode layer, electrochromic layer, electrolyte, edge sealant, etc. When powered on, the electrochromic layer changes color to achieve the color change of the image. However, during use, water vapor in the air will slowly penetrate into the electrolyte from the edge of the edge sealant, causing the pattern to display abnormally.
[0004] In view of this, how to provide an electrochromic packaging structure for an automobile rearview mirror that solves the above-mentioned technical problems has become a problem that those skilled in the art need to solve. Utility Model Content

The electrolyte layer is arranged between the first substrate and the second substrate, the first conductive layer is arranged between the electrolyte layer and the first substrate, and the second conductive layer is arranged between the electrolyte layer and the second substrate.

[0008] In one embodiment, the outer edges of the first substrate, the first conductive layer and the electrolyte layer are flush, the first substrate, the first conductive layer and the electrolyte layer are arranged in a stepped structure with the second conductive layer and the second substrate, and the sealant is filled in the stepped structure.
[0009] In one embodiment, both the first substrate and the second substrate are transparent base components.
[0010] In one embodiment, the inner surface of the first substrate is formed into a reflective surface by electroplating Ag or Al.
[0011] In one embodiment, the first conductive layer and the second conductive layer are both transparent conductive films.
[0012] In one embodiment, an electrochromic layer is provided on a side of the first conductive layer close to the electrolyte layer.
[0013] In one embodiment, an ion storage layer is provided on a side of the second conductive layer close to the electrolyte layer.
