In another embodiment, as shown in fig. 6, the included angle between the outer panel surface 111 and the outer wall surface 121 is an acute angle, the inner panel surface 112 is parallel to the outer panel surface 111, and the inner wall surface 122 is parallel to the outer wall surface 121, so that the included angle between the inner panel surface 112 and the inner wall surface 122 is an acute angle, and the thickness of the side wall part 120 is uniform. In another embodiment, as shown in fig. 7, the included angle between the outer panel surface 111 and the outer wall surface 121 is an acute angle, the included angle between the inner panel surface 112 and the inner wall surface 122 is an obtuse angle, and the thickness of the side wall portion 120 gradually decreases from the main body portion 110 to the end of the side wall portion 120.
As shown in fig. 4, in an embodiment, the main body 110 is a flat plate, the outer plate surface 111 and the inner plate surface 112 are parallel, and the thickness of the main body 110 is uniform. In another embodiment, as shown in fig. 8, the main body 110 has an arc-shaped curved surface. It can be understood that the outer plate surface 111 is an arc-shaped curved surface, the shape of the inner plate surface 112 is the same as that of the outer plate surface 111, and the outer plate surface 111 is parallel to the inner plate surface 112, so that the main body 110 is an arc-shaped curved plate with uniform thickness; alternatively, when the outer panel surface 111 is an arc-shaped curved surface and the inner panel surface 112 is a flat surface, the thickness of the main body portion 110 decreases from the middle to the two sides in the width direction. The arc-shaped outer plate surface 111 of the main body 110 and the smoothly-transitioned corners at the two sides of the casing 100 together make the entire upper surface of the casing 100 be a curved surface shape, so that the whole casing is smooth, and the casing 100 has a more beautiful appearance and better hand feeling.
The following description will be given taking a case where the main body 110 is a single rectangular plate glass. 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.
As shown in fig. 4 to 8, the thickness of the side wall part 120 is greater than that of the main body part 110. Compared with the case 100 with the same thickness, namely, the thickness of the sidewall 120 of the case 100 is equal to the thickness of the main body 110, the shape of the case 100 in the present application can be relatively more abundant, and has a higher identification degree. The thickness L2 of the main body 110 may be in the range of 0.6mm to 1.0mm, and the thickness L1 of the side wall 120 may be in the range of 1.5mm to 3.5 mm. It is understood that the thickness of the sidewall portion 120 refers to the overall thickness of the sidewall portion 120, and may be, for example, the average thickness of the sidewall portion 120. The thickness of the sidewall 120 may be different or the same. As shown in fig. 6, the thickness of the side wall portion 120 is uniform; as shown in fig. 4, 5, 7, and 8, the thickness of the side wall portion 120 may gradually decrease in a direction away from the main body portion 110; in other embodiments, the thickness of the sidewall portion 120 may increase and then decrease in a direction away from the main body portion 110 by the inner wall surface 122 protruding into the cavity 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.
The inner surface of the case 100 is covered with a decorative layer. 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.

The outer surface of the bead is processed such that an included angle between the outer surface of the bead and the outer panel surface 111 of the main body 110 is an acute angle, to obtain the side wall portion 120, and the thickness L1 of the side wall portion 120 ranges from 1.5mm to 3.5 mm. In other embodiments, the outer surface of the glass body may be machined by laser cutting or etching.

In one embodiment, the product obtained in step b is further processed and polished to obtain a shell 100 with a smooth and bright appearance. A film may be formed on the inner surface of the casing 100 by evaporation to serve as a decoration layer, and in other alternative embodiments, ink may be sprayed on the inner surface of the casing 100, or a film may be adhered to 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.
