preparation example Construction

[0054] According to a second aspect of the present invention, the present invention provides a method for preparing a housing, the method comprising the following steps:

[0055] S1. Provide an inner layer blank plate, an intermediate layer blank plate and an outer layer blank plate, the outer layer blank plate is one or more selected from stainless steel, titanium and titanium alloy, the inner layer blank plate and the The intermediate layer blank sheet is one or more selected from aluminum and aluminum alloys, and the hardness of the intermediate layer blank sheet is not higher than the hardness of the inner layer blank sheet;

[0056] S2. Roughening the surfaces to be bonded of the inner layer blanks, the surface to be bonded of the middle layer blanks, and the surface to be bonded of the outer layer blanks;

[0057] S3, rolling the surface to be bonded of the inner layer blank plate, the surface to be bonded of the intermediate layer blank plate, and the surface to be bond...

Embodiment 1

[0139] (1) The inner blank plate is an aluminum alloy plate with a grade of 5052 (hardness is 45HV), the middle layer blank is an aluminum alloy plate with a grade of 6063 (hardness is 33HV), and the outer blank is a stainless steel plate with a grade of SUS316L ( The hardness is 183HV).

[0140] (1-1) Pre-coarsening treatment

[0141] The inner layer blank sheet and the outer layer blank sheet are rolled respectively, and the rolling adopts a pair of rolling rotary rolls, one of the rolling rotary rolls in the pair of rolling rotary rolls is a smooth roll, and the other rolls The rotating roll is a rough roll, and the rough roll is in contact with the surface to be bonded, the surface of the smooth roll is a smooth surface, and the surface of the rough roll has lines, and the lines are perpendicular to the rolling axis of the rotating roll. In the direction, the pattern of the lines is a straight line, and the distance between two adjacent lines is in the range of 0.03-0.10m...

Embodiment 2

[0157] The mobile phone shell was prepared by the same method as in Example 1, except that the pre-roughening treatment in step (1-1) was not performed, but the roughening treatment was directly performed. The prepared composite sheet was peeled along a direction of 180 degrees, the middle layer and the outer layer were peeled off, and the middle layer and the inner layer maintained an integrated structure, wherein the bonding force between the middle layer and the outer layer was 16.9 N / mm.

Abstract

The invention discloses a shell, a preparation method thereof and an electronic product adopting the shell. The shell comprises a frame body, wherein at least a part of the frame body comprises an outer layer, a middle layer and an inner layer; the inner surface of the inner layer faces the interior of the frame body; the outer surface, far away from the inner surface of the inner layer, of the outer layer forms the outer surface of the frame body; the outer layer and the inner layer are connected through the middle layer, the material of the outer layer is selected from stainless steel, titanium and titanium alloy, the material of the inner layer and the material of the middle layer are respectively selected from aluminum and aluminum alloy, and the hardness of the material of the transition layer is not greater than that of the material of the inner layer. According to the shell disclosed by the invention, the inner layer and the outer layer of the frame body are made of different materials, so that the shell is high in strength and hardness, has higher brightness after being polished, and is easy for CNC processing; meanwhile, the processing procedure is shortened.

Description

technical field [0001] The invention relates to a casing and a preparation method thereof, and also relates to an electronic product. Background technique [0002] Existing terminal equipment casings (such as the middle frame of a mobile phone) are mostly processed by one kind of metal, such as aluminum alloy, stainless steel or titanium alloy. In recent years, with the emergence of high-gloss appearance effects of mobile phone exterior parts and the development trend of front and rear double-glass appearance designs, higher strength, higher brightness effects, and lightweight mobile phone middle frames have also become development hotspots. [0003] Aluminum alloy has low density, light weight, easy forming, and easy processing, but its strength is low, and the brightness after polishing is not high. Although stainless steel has the advantages of high strength, high hardness, and high brightness after polishing, it has a high density and is heavy for electronic equipment s...
