Shell of an electronic device, a manufacturing method thereof and an electronic device

Abstract

The invention provides a shell of an electronic device, a manufacturing method thereof and an electronic device. The shell of the electronic device includes a shell body, an anodic oxide layer and anoptical film layer, wherein the optical film layer includes a plurality of first sub-film layers and a plurality of second sub-film layers arranged alternately, and the first sub-film layer is formedof silicon oxide, and the second sub-film layer is formed of at least one of titanium oxide and niobium oxide. In the shell ofthe electronic device according to the present invention, an optical filmlayer is also arranged on the anodic oxide layer on the surface of the shell body, and the optical film layer is a plurality of layer of silicon oxide and titanium oxide or silicon oxide and niobium oxide alternately arranged, thus, the light is refracted many times between the film layers with different refractive indices, thereby realizing a magic color discoloration effect such as a rainbow onthe surface of the shell, and further enabling the appearance of the electronic device to meet the needs of consumers for the changeable appearance effect of the electronic device.

Description

technical field [0001] The present invention relates to the technical field of shell production of electronic equipment, and in particular, the present invention relates to a shell of electronic equipment, a manufacturing method thereof, and electronic equipment. Background technique [0002] At this stage, due to serious homogenization and aesthetic fatigue of the casings of electronic devices such as mobile phones, tablet computers, and smart watches, the surface effect of a single color can no longer meet consumers' needs for changing appearance effects of electronic devices. Moreover, aluminum alloy is commonly used as the housing of electronic equipment, and its surface needs to be anodized. However, the apparent color of the anodized layer is single, and it is impossible to achieve changing appearance effects. Contents of the invention [0003] An object of the embodiments of the present invention is to provide a casing structure of an electronic device, a method for...

Problems solved by technology

[0002] At this stage, due to the serious homogeneity and aesthetic fatigue of the casings of electronic devices such as mobile phones, tablet computers, and smart watches, the surface effect of a single color can no longer meet consumers' needs for changing appearance effects of electronic devices.

Moreover, the commonly used material for the housing of electronic equipment is aluminum alloy, and its surface needs to be anodized. However, the apparent color of the anodized layer is single, and it is impossible to achieve changing appearance effects.
