The sidewall portions 120 may be located at two opposite long sides of the main body portion 110, at two opposite short sides of the main body portion 110, and at the periphery of the main body portion 110, that is, the two long sides and the two short sides are both provided with the sidewall portions 120, so that the open box-shaped structure of the housing 100 can be realized.
By providing the sidewall 120 to make the casing 100 in an open box shape, when the mobile phone is assembled by using the casing 100, the battery (not shown), the main board (not shown), the display assembly 200, and other components of the mobile phone can be placed in the open box-shaped structure of the casing 100, without separately providing a middle frame. The distance H between one end of the side wall 120 away from the main body 110 and the main body 110 in a direction perpendicular to the main body 110 is 3.5mm to 8.5 mm. The H represents the depth of the case 100 having an open box structure, and the case 100 has a suitable depth, thereby ensuring that the battery, the main board, the display screen assembly 200, and other components of the mobile phone can be accommodated. Wherein the display panel assembly 200 is smoothly abutted with the sidewall 120 of the housing 100.

In the present application, the variation of the thickness of the sidewall 120 is not particularly limited.
The thickness of the sidewall 120 is relatively thick, and a structure matching with the motherboard and the display screen assembly 200 can be disposed on the inner side of the sidewall 120, so that the motherboard and the display screen assembly 200 can be directly mounted on the sidewall 120, and the structure of the mobile phone is simpler. Moreover, the thicker sidewall portion 120 facilitates the configuration of various shapes, such as different shapes of the sidewall portion 120 in fig. 4-6. The thickness of the body portion 110 is very thin and the main area on the housing 100 is the body portion 110, which makes the housing 100 relatively light in weight and fast in heat dissipation.

In one embodiment, a film may be formed on the inner surface of the casing 100 as a decoration layer by evaporation, and in other alternative embodiments, an ink may be sprayed on the inner surface of the casing 100, or a film may be adhered on the inner surface of the casing 100 to form a decoration layer. If the decoration layer is black, the inner structure of the mobile phone can be prevented from being seen through the casing 100, and the sidewall 120 and the main body 110 can be integrated into a single visual effect. Certainly, the decorative layer can also be provided with patterns to enhance the aesthetic property of the mobile phone rear shell.

10. A method of manufacturing a housing, comprising the steps of:
step a, providing flat glass, and hot-bending the edge of the flat glass to obtain a glass main body comprising a plate part and a bent edge;
step b, processing the outer surface of the glass main body to obtain a shell comprising a main body part and a side wall part;
wherein the thickness of the side wall part is larger than that of the main body part;
the main body part comprises an outer plate surface, the side wall part comprises an outer wall surface, an included angle formed by intersection of a tangent plane at any position of the outer wall surface and an extension plane of the outer plate surface is an acute angle, and the thickness of the side wall part is gradually reduced from the main body part to the end part of the side wall part; decorative layers are arranged on the inner surfaces of the main body part and the side wall part.
11. The method for manufacturing a housing according to claim 10, wherein the inner surface of the plate portion of the glass body after the hot bending and the inner surface of the bent edge are at an acute angle, an obtuse angle or perpendicular to each other.
12. The method for manufacturing the housing according to claim 10, comprising any one of:
the main body part is in a flat plate shape or an arc curved surface shape;
the outer wall surface is a plane or a curved surface;
the outer plate surface and the outer wall surface are in smooth transition.
13. The method of manufacturing a housing according to claim 10, wherein the thickness of the main body portion is 0.6mm to 1.0mm, and/or the thickness of the side wall portion is 1.5mm to 3.5 mm.
