In the embodiment of the present invention, the mounting portion 13 is used for mounting the camera decoration 100 on the terminal housing, and the side of the first decoration portion 11 away from the second decoration portion 12 is used for mounting the camera lens to protect the camera. In some embodiments of the present invention, the second decorative portion 12 protrudes a first predetermined height relative to the mounting portion 13 and the first decorative portion 11 protrudes a second predetermined height relative to the second decorative portion 12. That is, the first decorative portion 11 protrudes more than the second decorative portion 12 and protrudes higher from the terminal housing. The first preset height and the second preset height can be set according to actual needs.
In order to protect the camera lens and reduce the risk of scratching the lens, the first decorative part 11 is required to have a good wear resistance, in the embodiment of the present invention, the first decorative part 11 may be made of stainless steel, titanium alloy, or aluminum alloy, and the outer side is made of stainless steel or titanium alloy, wherein the inner side is a side facing the inside of the terminal, and the outer side is a side facing the outside of the terminal (i.e., a side serving as an appearance surface). The stainless steel and the titanium alloy have better wear resistance and can better protect the lens of the camera. In the embodiment of the invention, the outer surface of the first decorative portion 11 is formed with a first PVD (Physical vapor Deposition) plating layer. The first PVD plating enables the first decorative portion 11 to take on a target color appearance, such as black, a color of a wheel, etc., and the risk of the PVD plating wearing off the varnish is low. For better appearance comfort, the first PVD coating may be color compatible with the camera lens.
