Electrochromic automobile rear-view mirror body structure and production method thereof

Abstract

The invention relates to an electrochromic automobile rear-view mirror body structure and a production method thereof. The electrochromic automobile rear-view mirror body structure comprises a first substrate, a second substrate, electrochromic solution and a third substrate; the first substrate is conductive glass; the second substrate is also conductive glass, and is connected with the first substrate through adhesive, so that a sealed space is formed, and the sealed space is provided with an injection hole; the electrochromic solution is liquid and is injected into the sealed space; the third substrate is connected with the outer side of the second substrate through an optical adhesive layer. By means of the high light transmittance of the optical adhesive layer, a plurality of films do not have to be plated on the third substrate, metal with high reflectivity, such as silver, aluminium, aluminium-titanium alloy or aluminium alloy, can be chosen to be plated according to actual demand, or a plurality of plated films which are high-refractivity materials and low-refractivity materials matched with each other can be plated, and thereby special application can be achieved.

Description

technical field [0001] The invention relates to a body structure of an electrochromic automobile rearview mirror, in particular to an electrochromic automobile rearview mirror body structure developed by using an electrochromic solution and a manufacturing method thereof. Background technique [0002] According to the development of electronic technology, the current car rearview mirror no longer only has the rearview function. Developed to an electrochromic rearview mirror that can automatically adjust the reflectivity by photoelectric sensors. However, with the development of technology, many rearview mirrors can be equipped with electronic compass or reversing image. These new functions are usually accompanied by displays to remind driving directions or driving safety. [0003] Commonly used electrochromic mirror technology US5128799 such as Figure 6 As shown, this structure requires a silver layer 93 to be plated on the back of the second substrate 92 for reflection p...

AI Technical Summary

Problems solved by technology

However, because the optical effect reflected by the polarizing and reflecting substrate 96 is yellowish, and it is a plastic substrate, it is easy to cause scratches during the manufacturing process. In addition, if it is in a high temperature state for a long time, the polarizing and reflecting substrate will 96 has the risk of deformation, so it is necessary to add a multi-layer film coated glass 97 with optical compensation effect to protect and adjust the color temperature of the entire mirror body 9 after the polarizing and reflective substrate 96

[0006] In view of the fact that the above-mentioned US5128799 technology can no longer meet the requirements of the current automobile industry for driving assistance systems, and the US5818625 technology may cause the risk of mirror failure of the mirror body 9, although the structure mentioned in the latest technology US8282224 can make up for the shortcomings of the past technology. However, the material cost of the polarized and reflective substrate 96 used in the US8282224 is relatively high, and another piece of high-cost multilayer coated glass 97 is needed as a support and to compensate for its optical shortcomings. The need for lamination of multiple substrates also causes difficulty in production and a substantial increase in cost, which in turn makes the mirror body 9 expensive
