Description
Technical Field
The utility model relates to an electrochromic assembly for rearview mirrors.
Background
Currently, electrochromic lenses are one of important components in anti-dazzling automobile rearview mirrors, and a specific structure of electrochromic lenses is disclosed in China patent publication No. CN 207123692U. Electrochromic lenses typically include two layers of glass substrates, and existing electrochromic lenses typically need to meet sufficient thickness requirements to provide sufficient strength to the electrochromic lens to prevent the lens from cracking. Thus, a thicker glass substrate is typically used in an electrochromic lens, and the thicker the glass substrate, the more expensive it is, which results in a higher cost of the entire electrochromic lens, resulting in a reduction in price competitiveness of the electrochromic lens.
Disclosure of Invention

Further, the transparent substrate is made of plastic.
Further, there is provided a specific structure of the transparent substrate, wherein an arc chamfer is provided on an outer periphery of a front end portion of the transparent substrate.
Further provided is a thickness of the first glass substrate and the second glass substrate, each of which is 0.7mm.
Further provided is a specific structure of the electrochromic composite layer, the electrochromic composite layer comprising:

Further, the transparent conductive film layer is an ITO film layer.
Further, the rear surface of the transparent substrate is attached to the front surface of the first glass substrate through glue.
After the technical scheme is adopted, the thickness of the first glass substrate and the thickness of the second glass substrate are thinned due to the arrangement of the transparent substrate, the whole electrochromic assembly for the rearview mirror can have enough thickness through the arrangement of the transparent substrate, and then the strength of the electrochromic assembly for the rearview mirror can be improved, so that the problem that the electrochromic assembly for the rearview mirror is fragile and easy to break is avoided. As the thicknesses of the first glass substrate and the second glass substrate are reduced, the material cost is greatly reduced, the production cost is further reduced, and the price competitiveness of the product is improved. The first glass substrate and the second glass substrate are high in price, and larger cost can be saved by thinning the first glass substrate and the second glass substrate; the transparent substrate is low in price, and the thickness of the transparent substrate is slightly larger, so that the cost is little influenced.

Detailed Description
In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
As shown in fig. 1, an electrochromic assembly for a rear view mirror includes a transparent substrate 1, a first glass substrate 2, a second glass substrate 3, and an electrochromic composite layer;
the first glass substrate 2 is positioned in front of the second glass substrate 3;
the electrochromic composite layer is positioned between the first glass substrate 2 and the second glass substrate 3, and is respectively connected with the rear surface of the first glass substrate 2 and the front surface of the second glass substrate 3;
the rear surface of the transparent substrate 1 is connected with the front surface of the first glass substrate 2; specifically, since the transparent substrate 1 is provided, the thicknesses of the first glass substrate 2 and the second glass substrate 3 can be reduced, and the transparent substrate 1 can enable the whole electrochromic assembly for the rearview mirror to have enough thickness, so that the strength of the whole electrochromic assembly for the rearview mirror can be improved, and the problem that the electrochromic assembly for the rearview mirror is fragile and easy to break is avoided. As the thicknesses of the first glass substrate 2 and the second glass substrate 3 are reduced, the material cost is greatly reduced, the production cost is further reduced, and the price competitiveness of the product is improved. Further specifically, the first glass substrate 2 and the second glass substrate 3 are expensive, and a large cost can be saved by thinning the first glass substrate 2 and the second glass substrate 3; the transparent substrate 1 is cheap, and the thickness of the transparent substrate 1 is slightly larger, so that the cost is little affected.
In this embodiment, the transparent substrate 1 is made of plastic, and the outer peripheral portion of the front end portion of the transparent substrate 1 may be provided with a circular arc chamfer portion 4. Specifically, the arc chamfer portion 4 is obtained by 2.5D machining, namely, the shape of the arc chamfer portion 4 is carved by engraving and carving, and then the arc chamfer portion 4 is polished to polish the arc chamfer portion 4. In the prior art, the arc chamfer 4 needs to be processed on glass, the processing difficulty of engraving and polishing on glass is high, the operation is complex, the yield is low, and therefore the cost for processing the arc chamfer 4 on glass is high. The circular arc chamfer 4 in this embodiment is processed on the plastic transparent substrate 1, the difficulty of engraving and polishing on the plastic transparent substrate 1 is small, and the yield is high, so the processing cost of engraving and polishing on the plastic transparent substrate 1 is far lower than the processing cost on glass, thereby further reducing the manufacturing cost and improving the price competitiveness of the product.
As shown in fig. 1, the thicknesses of the first glass substrate 2 and the second glass substrate 3 may be 0.7mm, and compared with the glass substrate 3mm used in the prior art, the thicknesses of the first glass substrate 2 and the second glass substrate 3 in the embodiment are 0.7mm, so that the cost is greatly reduced.
As shown in fig. 1, the electrochromic composite layer may include:
a transparent conductive film layer 5 provided on the rear surface of the first glass substrate 2;
a reflective conductive film layer 6 provided on the front surface of the second glass substrate 3, the transparent conductive film layer 5 and the reflective conductive film layer 6 being respectively deposited by a magnetron sputtering method;
a frame glue 7 disposed between the outer peripheral portion of the transparent conductive film layer 5 and the outer peripheral portion of the reflective conductive film layer 6, wherein a filling space is formed around the inner side of the frame glue 7;
the electrochromic solution 8 filled in the filling space.
As shown in fig. 1, a shielding ring 9 for shielding the frame glue 7 is arranged between the rear surface of the transparent substrate 1 and the front surface of the first glass substrate 2; in this embodiment, the shielding ring 9 may be a chromium ring plated on the rear surface of the transparent substrate 1. Of course, the shielding ring 9 may be a chromium ring plated on the front surface of the first glass substrate 2.
In this embodiment, the transparent conductive film layer 5 may be an ITO film layer, and the rear surface of the transparent substrate 1 and the front surface of the first glass substrate 2 may be attached by glue.
In summary, since the transparent substrate 1 is provided, the thicknesses of the first glass substrate 2 and the second glass substrate 3 can be reduced, and the transparent substrate 1 can provide a sufficient thickness for the entire electrochromic device for a rear view mirror, so that the strength of the entire electrochromic device for a rear view mirror can be improved, and the problem that the electrochromic device for a rear view mirror is fragile and easy to break can be avoided. As the thicknesses of the first glass substrate 2 and the second glass substrate 3 are reduced, the material cost is greatly reduced, the production cost is further reduced, and the price competitiveness of the product is improved. Wherein the first glass substrate 2 and the second glass substrate 3 are expensive, and a large cost can be saved by thinning the first glass substrate 2 and the second glass substrate 3; the transparent substrate 1 is cheap, and the thickness of the transparent substrate 1 is slightly larger, so that the cost is little affected.
