Casing of mobile terminal and manufacturing method of casing

Abstract

The invention provides a casing of a mobile terminal and a manufacturing method of the casing. The casing comprises a frame, a glass screen which covers the front end surface of the frame and a rear cover which covers the rear end surface of the frame, an accommodation space is formed by the frame and the rear cover, the frame is made of amorphous alloy, the intensity of the amorphous alloy frame is greater than 1800MPa, and the rear cover is a ceramic rear cover. Compared with the prior art, the compound mobile-terminal casing of the invention has a beautiful appearance and high anti-falling capability.

Description

[0001] 【Technical field】 [0002] The invention relates to a casing of a mobile terminal. [0003] 【Background technique】 [0004] The shell designs of existing mobile terminals mainly include ceramic back cover and aluminum alloy middle frame composite structure, plastic back cover and aluminum alloy middle frame composite structure, all-plastic back cover, all-ceramic back cover and all-aluminum alloy back cover, etc. . [0005] Aluminum alloy materials can be polished / sandblasted / drawn / and other surface treatments, and can also be colored and painted in various colors after anodizing, so the appearance is widely accepted by the public. However, the strength of the aluminum alloy material is not high enough, and defects such as drop deformation, bending, and pits appear during use. The ceramic material has low thermal conductivity and low specific heat capacity, so it feels warm and moist like jade. Because of its high refractive index and strong dispersion, it looks "white...

Problems solved by technology

However, the strength of the aluminum alloy material is not high enough, and defects such as drop deformation, bending, and pits appear during use

The ceramic material has low thermal conductivity and low specific heat capacity, so it feels warm and moist like jade. Because of its high refractive index and strong dispersion, it looks "white as jade and bright as a mirror", and has a good visual effect. In addition, It also has high hardness and wear resistance, and the Mohs hardness is above 8, but the ceramic material is brittle and fractured, so it has a fatal weakness, and it is easy to break and shatter

The plastic material molding process is mature and the raw material is cheap, but the feel and appearance of the plastic mobile phone back cover are not as good as ceramics and aluminum alloys, giving people a cheap feeling and not suitable for mid-to-high-end mobile phones.
