In order to further describe the shell structure of the embodiment of the present application, carried out below by taking method for producing shell as an example detailed
Explanation.It should be noted that method for producing shell can specifically include bonnet preparation method, center preparation method.Housing below
Preparation method illustrates by taking bonnet preparation method as an example, and the bonnet in the bonnet preparation method can be understood as housing system
Make the housing base material in method.It is understood that the embodiment of the present application method for producing shell is not limited to bonnet.
Also referring to Figure 13, Figure 13 is the schematic flow sheet for the bonnet preparation method that the embodiment of the present application provides.After this
Lid preparation method comprises the following steps：
In a step 101, there is provided a bonnet.The bonnet can be metal material, such as aluminium, further, such as aluminium
Alloy.It should be noted that the bonnet can be directly commercially available, sheet fabrication can also be obtained, such as to aluminium alloy plate
The PROCESS FOR TREATMENTs such as material is forged and pressed, timeliness obtain.
Wherein, the bonnet can include inner surface and outer surface, the bonnet and its inner surface, the outer surface being oppositely arranged
Above content can be referred to, will not be repeated here.
In a step 102, the outer surface of bonnet is processed by shot blasting.So that rear exterior surface is smooth.
In certain embodiments, rear exterior surface can be realized by the way of machinery, chemistry or electrochemistry and polished.
To cause the reduction of bonnet surface roughness, to obtain bright, flat surface rear exterior surface.Wherein, chemical polishing mode is
Regular dissolving is carried out to rear exterior surface and reaches smooth.Wherein, electrochemical polish mode be using rear exterior surface as
Anode, it is insoluble be nearly negative electrode, two-stage is immersed in electrolytic cell simultaneously, logical direct current and produce selective anodic dissolution,
So that the increase of bonnet exterior surface gloss degree is big.The mode wherein mechanically polished is by bonnet appearance of cutting or polish
Face so that rear exterior surface plastic deformation removes the convex portion after polishing and obtains even surface.For example, in certain embodiments, can
To be polished using the less grinding wheel of granularity housing substrate outer surface, to realize the throwing to housing substrate outer surface
Light processing.
In certain embodiments, before being processed by shot blasting to the outer surface of bonnet, first rear exterior surface can be entered
Row grinding process, then the rear exterior surface after grinding process is processed by shot blasting again, makes polishing better.
In step 103, oxidation processes at least twice are carried out to the rear exterior surface after polishing.
In certain embodiments, once oxidation processing can be carried out to the rear exterior surface after blasting treatment, forms one layer
Oxide layer, in other words layer oxide film.Coloring treatment can also be carried out after once oxidation processing, exterior surface color after formation.
Few oxidation processes twice are also proceeded to, to form at least two layers of oxide layer, or perhaps at least two layers of oxide-film.Oxidation
Oxidation every time can be coloured after processing, and then form required appearance color.Such as：After can be to polishing
Exterior surface carries out oxidation processes twice afterwards, to form two layers of oxide layer, and carries out coloring treatment after the oxidising treat-ment, and then
Appearance color needed for being formed.Specifically, referring to Figure 14, the Figure 14 is the flow of the embodiment of the present application bonnet oxidation processes
Schematic diagram.Oxidation processes specifically include twice for this：
In step 1031, first time oxidation processes are carried out to the rear exterior surface after polishing, form the first oxidation
Layer.After the first time oxidation processes, coloring treatment can also be carried out, the appearance color of exterior surface after being formed, such as
Black, white etc..
In step 1032, machining processes are carried out to the rear exterior surface after first time oxidation processes, with described
The edge of exterior surface forms an at least arc area, arc area 1321 as shown in figure 16 afterwards.Wherein, the arc
Region can be C angles.Specifically, CNC (Computer numerical control, computer numerical control (CNC) machine can be used
Bed) process C angles.In step 1033, second of oxidation processes, shape are carried out to the rear exterior surface after machining processes

After gel, then by the method for spraying, spin coating or immersion second layer precursor sol is arranged on first layer gel,
By way of drying or heating, second of precursor sol is set to form second layer gel, the like, can be by more
The secondary mode that precursor solution is set, adjust the thickness of gel.Finally, the bonnet is heat-treated, to cause gel to pass through
Cross chemical reaction and form photocatalysis film, so as to form self-cleaning layer.
It should be noted that in certain embodiments, machining processes are carried out to the rear exterior surface, with institute
After the edge formation at least arc area for stating rear exterior surface, second of oxygen can not be carried out to the rear exterior surface
Change is handled, and directly the arc area of exterior surface forms self-cleaning layer in the rear, and it is thin that the self-cleaning layer includes photocatalysis
Film.Now, the self-cleaning layer is formed directly into the arc area of table outside the bonnet.
In certain embodiments, as shown in figure 17, shape can be distinguished at the both sides of the edge of exterior surface 132 in the rear
Into two arc area 1321 (i.e. C angles), and second is carried out to two arc areas 1321 (i.e. C angles) and is aoxidized, with
Two arc areas 1321 (i.e. C angles) all form the second oxide layer 138.
By oxidation processes twice not only to the protecting effect of rear exterior surface more preferably, and formed after aoxidizing twice
Second oxide layer and the adhesion of skin of paint are more preferable.It should be noted that in some embodiments, can also be to polishing after
Rear exterior surface carry out three times oxidation or more time oxidation processes.
It should be noted that the embodiment of the present application can also be after polishing rear exterior surface carry out once oxidation
Processing.Layer of oxide layer, or perhaps oxide-film are formed in rear exterior surface.When carrying out once oxidation processing, in order to increase
Adhesion between skin of paint and oxide layer, one layer of particle can be formed in oxide layer by the way of physical vapour deposition (PVD)
Layer, spray painting processing is then carried out on stratum granulosum again, form skin of paint.Stratum granulosum can increases oxide layer and skin of paint
Adhesion, to the protecting effect of housing outer surface more preferably.
