Detailed ways

Please refer to FIGS. 1-4 , which show a specific embodiment of a lens protection lens structure 1 for protecting a lens of an electronic product according to the present invention, which includes an artificial sapphire lens 2 , a metal frame 3 , a A first adhesive layer 4 and a second adhesive layer 5 .

The aforementioned artificial sapphire lens 2 has a front surface 20 and a back surface 22 located on opposite sides. The front surface 20 is formed by evaporation treatment to form an anti-fouling layer 202, and the back surface is provided with an ink layer 222 on the edge ring, and is formed by processing. An anti-reflection coating layer 224 .

The aforementioned metal frame base 3 is a hollow frame base, and has an upper frame surface 30 and a lower frame surface 32 located on opposite sides; A second joint portion 322 is provided. In this embodiment, the metal frame base 3 is an annular metal frame base, and the first joint portion 302 and the second joint portion 322 are respectively recessed on the upper frame surface 30 and the lower frame surface 32 thereof; and The first joint portion 302 and the second joint portion 322 can be arranged to form an annular groove by circling the upper and lower frame surfaces, or can also only form an arc-shaped groove that partially circumnavigates.

In practice, the metal frame is preferably an aluminum ring frame (such as a high-hardness aluminum alloy ring frame) or a steel ring frame (such as a stainless steel ring frame), and can also be in other shapes or other suitable shapes. made of metal material. Through the existing electroplating process (such as hardening electroplating process or titanium burning electroplating process), the aforementioned metal frame can be given bright colors, thereby adding visual beauty and richness.
