Pouring structure for pouring electrochromic liquid into electrochromic rearview mirror

Abstract

The invention provides a pouring structure for pouring electrochromic liquid into an electrochromic rearview mirror. The structure comprises a glass shell, wherein the glass shell is formed by bondinga front glass substrate and a rear glass substrate through epoxy resin glue on peripheries of the front glass substrate and the rear glass substrate, the inner cavity capable of being filled with theelectrochromic liquid is a cavity body which is positioned between the front glass substrate and the rear glass substrate and is sealed and surrounded by epoxy resin glue adhered to the peripheries of the front glass substrate and the rear glass substrate, one end of the glass shell is provided with a liquid inlet opening through which the electrochromic liquid enters the inner cavity of the glass shell in a suction or pressure injection manner, the other end of the glass shell is provided with a liquid outlet opening from which the electrochromic liquid flows out after the inner cavity of the glass shell is filled with the electrochromic liquid, after the glass shell is filled with the electrochromic liquid, colloid capable of sealing the liquid inlet opening and the liquid outlet opening is arranged at the liquid inlet opening and the liquid outlet opening respectively. The structure is advantaged in that the electrochromic liquid can be filled in a normal-pressure environment, filling operation is simple, and manufacturing is convenient.

Description

technical field [0001] The invention relates to the technical field of making anti-glare mirrors for automobiles, in particular to a filling structure for filling electrochromic liquid in electrochromic rearview mirrors. Background technique [0002] There is an existing Chinese invention patent application with the application number CN201310593580.5 titled "Encapsulation Method for Manufacture of Electrochromic Anti-glare Device for Vehicles", which discloses an electrochromic anti-glare device that needs to be introduced into the conductive area of ​​the electrode in the conductive layer of the glass substrate. Carry out edge grinding and chamfering to increase the cross-sectional area of ​​the conductive silver glue packaging manufacturing method, according to the need to reduce the electrochromic anti-glare device packaging and electrode lead-out area and increase the visible area of ​​the color-changing device structure, further use etching, vacuum The electrochromic a...

AI Technical Summary

Problems solved by technology

However, this encapsulation method uses a small section of non-glue-coated section as the injection port for filling the electrochromic material, so the injection process of the electrochromic material needs to be kept in a vacuum environment, which requires a high degree of vacuum in the environment, and the injection operation is not It is very convenient, so this method needs to be further improved
