In practice, the metal frame base is an aluminum ring frame base or a steel ring frame base; in one embodiment, the aluminum ring frame base is an aluminum alloy ring frame base; in another embodiment The aforementioned steel ring frame base is a stainless steel ring frame base.

During implementation, the thickness of the first adhesive layer is between 0.01 mm and 0.09 mm.

In practice, the first coupling portion is recessed on the upper frame surface of the metal frame base, and/or the second coupling portion is recessed on the lower frame surface of the metal frame base.

FIG. 5 is a schematic diagram of the use of the lens protection lens structure of the creative embodiment.

Please refer to Figures 1-4, which shows a specific embodiment of the lens protector structure 1 of this invention for protecting a lens of an electronic product, which includes an artificial sapphire lens 2, a metal frame 3, a The first glue layer 4 and a second glue layer 5.

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

The aforementioned metal frame base 3 is a hollow frame base, and has an upper frame surface 30 and a lower frame surface 32 on opposite sides; the upper frame surface 30 is provided with a first coupling portion 302 on the lower frame surface 32 is provided with a second combining portion 322. In this embodiment, the metal frame base 3 is an annular metal frame base, and the first coupling portion 302 and the second coupling portion 302 are respectively recessed on the upper frame surface 30 and the lower frame surface 32; and The first and second coupling parts are arranged on the upper and lower frame surfaces to form a ring-shaped groove, or only partially-circular arc grooves.
