Ceramic mobile phone back cover and forming process thereof

Abstract

The invention discloses a ceramic mobile phone back cover. The ceramic mobile phone back cover comprises a back cover body; the back cover body is a metal back cover body; an argil filling hole is formed in the back plate; the outer surface, except for the argil ceramic filling hole, is coated with a non-conductive ceramic material layer; the argil filling hole is filled with a non-conductive ceramic material filler; the non-conductive ceramic material layer and the non-conductive ceramic material filler are sintered integrally to be fixed at the back cover body; and penetration holes matchingwith functional holes are formed at the positions corresponding to the functional holes of the non-conductive ceramic material layer. Compared with the prior art, the ceramic mobile phone back cover,combining the advantages the metal back cover and the advantages of the ceramic, has the advantages of being light, thin, strong in structural intensity, high in surface hardness, good in scratch resistance, good in appearance consistence, high-end and beautiful, good in heat radiation and free from electromagnetic signal interference problem. The invention also discloses a forming process of theceramic mobile phone back cover.

Description

technical field [0001] The invention relates to mobile phone accessories, in particular to a mobile phone back cover and its forming process. Background technique [0002] Traditionally sold mobile phone back covers are generally made of plastic, glass, metal (mainly aluminum) and ceramics, and they have different types of defects. For example: 1) The plastic back cover is low in cost, easy to process, and has no electromagnetic signal interference problems, but the surface is not scratch-resistant, poor in texture, poor in structural strength, and poor in heat dissipation; 2) Although the glass back cover has a scratch-resistant surface and a texture Yes, there is no electromagnetic signal interference problem, but the glass is fragile when it falls, and it cannot be used as a structural support, so a metal middle frame should be designed in conjunction with the glass as the structural support of the whole machine, which is costly and complicated; 3) metal aluminum Althoug...

Problems solved by technology

For example: 1) The plastic back cover is low in cost, easy to process, and has no electromagnetic signal interference problems, but the surface is not scratch-resistant, poor in texture, poor in structural strength, and poor in heat dissipation; 2) Although the glass back cover has a scratch-resistant surface and texture Yes, there is no electromagnetic signal interference problem, but the glass is fragile when dropped, and it cannot be used as a structural support, so a metal middle frame should be designed in conjunction with the glass as the structural support of the whole machine, which is costly and complicated; 3) metal aluminum Although the high-quality back cover has the advantages of good structure, good heat dissipation, and good scratch resistance, due to the electromagnetic signal interference problem of metal, all metal back covers need to be inlaid with a piece of plastic antenna strip at the upper and lower ends, so that the electromagnetic signal can be transmitted. Emit normally so that the appearance is not consistent
