Also referring to Fig. 4, Fig. 4 is profiles of the Fig. 3 in A-A directions.Rear cover 13a can include rear cover substrate 137,
Oxide layer 134 and skin of paint 136.
Wherein, rear cover substrate 137 can use aluminium, such as aluminium alloy.The rear cover substrate 137 includes 131 He of inner surface
Outer surface 132, the inner surface of the rear cover substrate 137 can be understood as the inner surface of rear cover 13, and the rear cover substrate 137 is outer
Surface can be understood as the outer surface before the non-oxidation processes of rear cover, spray painting processing etc..137 rear cover 13a tools of the rear cover substrate
Have same first at 111, second the 112, the 3rd in 113 and the 4th while 114.
Wherein, oxide layer 134 is formed on the outer surface 132 of rear cover substrate 137.The oxide layer 134 can be by once
Oxidation forms layer of oxide layer 134.Such as：Monochrome oxidation forms the oxide layer 134, specifically can be by being carried out after oxidation technology
Coloring is formed.It should be noted that in some embodiments, it is also possible to formed using oxidation twice or oxidation more than twice
Multilayer oxide layer.
Such as：Referring to Fig. 5, Fig. 5 is another profiles of the Fig. 3 in A-A directions.Fig. 5 and Fig. 4 difference lies in：Rear cover
The oxide layer 134 of 13b includes two layers, i.e. the first oxide layer 1341 and the second oxide layer 1342.First oxide layer 1341 is formed in
On the outer surface 132 of rear cover substrate 137, the second oxide layer 1342 is formed in the first oxide layer 1341, in certain embodiments,
Second oxide layer can only cover the part in the first oxide layer.First oxide layer 1341 and the second oxide layer 1342 can
With increase and the combination power of skin of paint 136.Wherein, the sandwich construction on oxide layer, no longer illustrates one by one herein.One
In a little embodiments, which can be colored oxide layer, and the second oxide layer can also be colored oxide layer.First oxygen
The color for changing layer can be different from the color of the second oxide layer, can also be identical.
Wherein, skin of paint 136 is formed in oxide layer 134, oxide layer 134 be located at skin of paint 136 and rear cover substrate 137 it
Between.In certain embodiments, one layer of paint can be sprayed in oxide layer 134 and forms the skin of paint 136.The skin of paint 136 is located at
The outermost layer of 13 outer surface of rear cover, its surface is smooth, and fingerprint not easy to stick, exterior surface cleaning is smooth after can keeping.
It should be noted that in some embodiments, it is also possible to two layers of paint or more than two layers are sprayed in oxide layer 134
Paint, to form two layers of skin of paint or multilayer skin of paint.Such as：Referring to Fig. 6, Fig. 6 is another sections of the Fig. 3 in A-A directions
Figure.Fig. 6 and Fig. 4 difference lies in：The skin of paint 136 of rear cover 13c includes the first skin of paint 1361 and the second skin of paint 1362.Should
First skin of paint 1361 is formed in oxide layer 134, which is formed on the first skin of paint 1361.At some
In embodiment, the thickness of the second skin of paint 1362 is more than the thickness of the first skin of paint 1361, further, the second skin of paint 1362
Thickness be twice of thickness of the first skin of paint 1361, for example the thickness of the second skin of paint 1362 is 10um, the first skin of paint
1361 thickness is 5um.It should also be noted that, the second skin of paint 1362 and the first skin of paint 1361 in process of production may
There are certain error amount, for example error amount is 0.5um.The setting of second skin of paint and the first paint layer thickness can be to rear cover
Outer surface provides preferably protection, and so that is bonded between two layers of skin of paint even closer.
For another example：Referring to Fig. 7, Fig. 7 is another profiles of the Fig. 3 in A-A directions.Fig. 7 and Fig. 4 difference lies in：Afterwards
The skin of paint 136 of lid 13d includes the first skin of paint 1361, the second skin of paint 1362 and the 3rd skin of paint 1363.First paint
Layer 1361 is formed in oxide layer 134, which is formed on the first skin of paint 1361, the 3rd skin of paint
1363 are formed on the second skin of paint 1362.Formed in oxide layer 134 two layers or three layers of skin of paint can increase oxide layer and
The combination power of skin of paint, to the protecting effect of rear cover more preferably.In certain embodiments, the thickness of the 3rd skin of paint 1363 is more than the
Two skin of paints 1362, the thickness of the second skin of paint 1362 are more than the thickness of the first skin of paint 1361.Further, the 3rd skin of paint
1363 thickness is twice of the thickness of the second skin of paint 1362, and the thickness of the second skin of paint 1362 is the first skin of paint 1361
Twice of thickness, for example the thickness of the 3rd skin of paint 1363 is 8um, the thickness of the second skin of paint 1362 are 4um, the first skin of paint
1361 thickness is 2um.
In certain embodiments, the thickness of the 3rd skin of paint 1363, the second skin of paint 1362 and the first skin of paint 1361 according to
Secondary equal thickness is reduced, for example the thickness of the 3rd skin of paint 1363 is 9um, and the thickness of the second skin of paint 1362 is 6um, and first paints
The thickness of layer 1361 is 3um.The setting of 3rd skin of paint, the second skin of paint and the first paint layer thickness can be to rear exterior surface
Preferably protection is provided, and so that is bonded between three layers of skin of paint even closer.
In certain embodiments, which transparent can be set.It should be noted that when skin of paint is at least two layers
When, wherein at least one layer of skin of paint transparent can be set.Further, the transparent setting of all skin of paints.Aoxidized with rear cover
Layer is the appearance face color of rear cover.
In order to increase the combination power between skin of paint 136 and oxide layer 134, in certain embodiments, referring to Fig. 8, Fig. 8
For another profiles of the Fig. 3 in A-A directions.Fig. 8 and Fig. 4 difference lies in：Rear cover 13e can also include binder course 135.The knot
