Aluminum alloy shell and preparation method and individual electronic equipment

Abstract

The invention discloses an aluminum alloy shell and a preparation method and individual electronic equipment thereof. The aluminum alloy shell comprises an aluminum alloy substrate (1) and an oxidation film layer (2), wherein a slit (3) is formed in the aluminum alloy substrate (1); the oxidation film layer (2) comprises an inner anode oxidation film layer (21) and an outer anode oxidation film layer (22); the inner anode oxidation film layer (21) is provided with inner anode oxidation film layer nano holes; the outer anode oxidation film layer (22) is provided with outer anode oxidation filmlayer nano holes; and the inner anode oxidation film layer nano holes and the outer anode oxidation film layer nano holes are separately independently filled with dye. When seen from the surface of the outer side of the shell, the aluminum alloy shell is a continuous metal layer, and the slit in the metal layer can serve as an antenna groove. The oxidation film layer on the surface of the metal layer has a good shielding effect, thus, the appearance of the slit is invisible, and the shell is neat and smooth. The aluminum alloy shell has good metal texture.

Description

technical field [0001] The invention relates to the field of material chemistry, in particular to an aluminum alloy casing, a preparation method thereof, and personal electronic equipment. Background technique [0002] The mobile phone antenna is a device used to receive signals on the mobile phone. Currently, most smartphones on the market have built-in antennas, which requires that the back cover of the mobile phone cannot shield the signal. Metal has a strong absorption of electromagnetic waves. When wifi, 2G, and 3G signals are injected into metal materials, absorption and attenuation will occur. Electromagnetic waves cannot reach the signal receiving module, resulting in signal shielding. Therefore, for metal body mobile phones, how to solve the signal shielding problem is one of the keys in its design and manufacture. At present, most mobile phones with metal bodies adopt the method of opening antenna slots and injection molding to solve the problem of signal shieldin...
