Outer casing adopting composite structure and manufacture process thereof

Abstract

The invention discloses an outer casing adopting a composite structure and a manufacture process thereof. The outer casing adopting the composite structure comprises an outer casing main body and an internal structure, wherein the internal structure is fixed on the inner side of the outer casing main body, the outer casing main body is made of a first material, and the internal structure is made of a second material. Through the composite structure and the manufacture process, the outer casing of a mobile terminal has the advantages of the two materials, so that the required appearance effect is realized, and the weight of parts is reduced; the outer casing is closely connected with the mobile terminal; and the manufacturing cost of parts is reduced by 30-60% compared to the manufacturing cost of parts which are all made of stainless steel materials.

Description

technical field [0001] The invention relates to the communication field, in particular to a composite structure casing and a manufacturing process. Background technique [0002] For quite a long period of time, mobile terminals have been developing in the direction of compactness, refinement, thinness, and light weight. Requirements - heavy hand feel. [0003] The simple way for manufacturers to achieve this goal is to use metal casings to increase the weight, appearance and stability of products. Strengthening the overall firmness of the mobile terminal with metal materials will undoubtedly greatly extend the lifespan, and also enable the mobile terminal to get rid of the cheap feeling brought by engineering plastics. [0004] However, the existing metal shells of mobile terminals are generally produced by stainless steel stamping or aluminum alloy stamping, combined with CNC machine tool processing and other processes. Simply use stainless steel stamping combined with C...

AI Technical Summary

Problems solved by technology

Simply use stainless steel stamping combined with CNC machine tools to make the shell, and the surface of the shell can achieve high-gloss, frosted and other appearance effects after simple treatment, but the shell made in this way is too heavy, which will inevitably cause inconvenience in use, and the cost is high High; purely using aluminum alloy stamping combined with CNC machine tool to make the shell, compared with pure stainless steel shell, its advantage is that the weight is much lighter, and the relative cost is relatively low, but the disadvantages are also obvious. The surface of the finished shell is very easy to be scratched. When it is hit, it may cause damage to the internal components of the mobile terminal due to insufficient strength. However, it is also selected as the shell material by many manufacturers because it is easy to process.

[0005] Obviously, stainless steel or aluminum alloy has its own advantages and disadvantages as a single material. Because a single material is used, the shell of a mobile terminal is often processed with a single structure, and it is inevitable to bear the advantages and disadvantages of a single material.
