Electrochromic Device

Abstract

An electrochromic device includes an outer frame, an electrochromic element arranged in the outer frame, a light transmission protection plate and a decorative frame layer. The electrochromic element comprises two substrates, two transparent layers, an ion conductor layer, an electrochromic layer and an ion storage layer. The protection plate is located at the front side of the electrochromic element to protect the electrochromic element, and the decorative frame layer can shield the surrounding part of the electrochromic element. By the design of the protection plate and the decorative frame layer, and after the protection plate and the decorative frame layer are fixed to the electrochromic element, the surrounding part of the electrochromic element that does not want to be observed can be shield, thereby being very convenient to assemble. Moreover, the overall electrochromic device of the present invention is simple to manufacture, and is lower in cost.

Description

Technical field [0001] The invention relates to an electrochromic device, in particular to an electrochromic device that can be applied to rearview mirrors of cars, industrial glasses, military glasses, building windows and the like. Background technique [0002] Electrochromic lenses can be used in car rearview mirrors, industrial / military glasses, energy-saving smart windows in buildings, etc. Take the rearview mirror of a car as an example. The electrochromic lens can quickly change the color of the lens and has the advantage of anti-glare. [0003] Refer to figure 1 , 2 , An existing electrochromic device applicable to rearview mirrors mainly includes an electrochromic lens 93, a first outer frame 91 defining a cavity 910, and a first outer frame 91 the second outer frame 92 on the front side. The electrochromic lens 93 is installed in the cavity 910 of the first outer frame 91, and its structure mainly includes two front and rear facing glass substrates 931, and two are resp...

Problems solved by technology

But because setting the metal guard 94 is less attractive, after the electrochromic lens 93 is installed in the first outer frame 91, the second outer frame 92 must be additionally provided to cover the metal guard 94 , so that the viewer will not see the metal guard 94 from the front of the device

However, the additional setting of the second outer frame 92 results in additional mold opening and high cost, and because the first outer frame 91 and the second outer frame 92 are a combination of plastic frames, the combination structure between the two must be considered ( figure 1 It is only for illustration, and the alignment of its detailed bonding structure) is not drawn, which makes the subsequent bonding process more troublesome

And therefore make the overall structure more rigid and unsightly
