Referring to fig. 1 to 3, in an embodiment, the electronic device 10 is a mobile phone, and the electronic device 10 includes a housing 100 and a display assembly 200, where the housing 100 serves as a rear shell of the electronic device 10. In other alternative embodiments, the housing 100 may be a cover plate for the display assembly 200 in the electronic device 10. In the following description, the case 100 is taken as a rear case of a mobile phone as an example.
In one embodiment, the housing 100 is formed of glass or optical ceramic and includes a body portion 110 and a sidewall portion 120. The sidewall portion 120 is extended from the edge of the body portion 110 such that the housing 100 has an open box shape. The thickness of the sidewall portion 120 is greater than the thickness of the body portion 110.
Specifically, as shown in fig. 4, the main body 110 includes an outer panel surface 111 and an inner panel surface 112. The side wall 120 includes an outer wall surface 121 and an inner wall surface 122. The outer wall surface 121 is connected to the outer plate surface 111, and the inner wall surface 122 is connected to the inner plate surface 112. The outer panel surface 111 and the outer wall surface 121 form the outer surface of the housing 100, and the inner panel surface 112 and the inner wall surface 122 form the inner surface of the housing 100.
As shown in fig. 4, in one embodiment, the transition between the body portion 110 and the sidewall portion 120 is smooth. It is understood that a smooth transition between the inner 112 and inner 122 surfaces and/or a smooth transition between the outer 121 and outer 111 surfaces. Therefore, the edge of the main body 110 is prevented from being angular, the smoothness of the corners of the side wall 120 and the main body 110 is ensured, the side wall 120 and the main body 110 have better visual effect when being seen from the outside of the shell 100 to the inside, and the hand feeling of a user is improved.
As shown in fig. 4, in one embodiment, the main body portion 110 is perpendicular to the side wall portion 120. It will be appreciated that the outer wall surface 121 is perpendicular to the outer wall surface 111 without limitation between the inner wall surface 112 and the inner wall surface 122, i.e., the inner wall surface 112 and the inner wall surface 122 may be perpendicular or at an obtuse angle. In another embodiment, as shown in fig. 5, the body portion 110 and the sidewall portion 120 form an obtuse angle therebetween. It will be appreciated that the outer wall surface 121 is at an obtuse angle to the outer wall surface 111, while there is no limitation to the inner wall surface 112 and the inner wall surface 122, i.e., the inner wall surface 112 and the inner wall surface 122 may be perpendicular or at an obtuse angle.
As shown in fig. 4, in one embodiment, the body 110 is flat. In another embodiment, as shown in fig. 6, the main body 110 has an arc-shaped curved surface, that is, the outer plate surface 111 has 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. In other embodiments, the main body 110 has an arc-shaped curved surface, and it is also understood that the outer plate 111 has an arc-shaped surface, the inner plate 112 has a plane, and the thickness of the main body 110 is greatest at the longitudinal central axis and smallest at both sides. The curved outer plate surface 111 of the main body 110 and the smoothly transition corners on both sides of the housing 100 together make the entire upper surface of the housing 100 have a curved shape, and the whole is smooth, so that the housing 100 has a more attractive appearance and better hand feeling.
As shown in fig. 4, in an embodiment, the outer wall surface 121 of the sidewall 120 is a plane, and the thickness of the sidewall 120 is uniform. In another embodiment, as shown in fig. 7, the outer wall surface 121 is curved, so that the outer wall surface 121 and the outer plate surface 111 are smooth, and the appearance of the housing 100 is more attractive and has better hand feeling. The thickness of the sidewall 120 gradually increases from the body 110 toward the end of the sidewall 120, increasing the thickness difference between the body 110 and the sidewall 120, increasing the three-dimensional sense of the housing 100, and improving the aesthetic feeling of the housing 100.
The following description will take as an example a straight glass in which the main body 110 is a single rectangular piece. The side wall 120 may be located at two opposite long sides of the main body 110, two opposite short sides of the main body 110, or around the main body 110, that is, the two long sides and the two short sides are both provided with the side wall 120, which can realize an open box structure of the housing 100.
By providing the side wall portion 120 to make the housing 100 in an open box shape, when the housing 100 is used to assemble the mobile phone, the battery (not shown), the main board (not shown), the display assembly 200, and other components of the mobile phone can be put into the open box structure of the housing 100 without separately providing a middle frame. Wherein, in the direction perpendicular to the main body 110, the distance H between the end of the side wall 120 away from the main body 110 and the main body 110 is 3.5mm to 8.5mm. The above-mentioned H represents the depth of the casing 100 of the open box structure, and by making the casing 100 have a proper depth, it is further ensured that the components such as the battery, the main board and the display assembly 200 of the mobile phone can be accommodated. Wherein the display assembly 200 is smoothly abutted with the sidewall portion 120 of the case 100.
As shown in fig. 4 to 7, the thickness of the sidewall portion 120 is greater than that of the body portion 110. Compared with the case 100 with equal thickness, i.e. the thickness of the side wall 120 in 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 richer, and has higher recognition 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 3.5mm. It is understood that the thickness of the sidewall portion 120 refers to the overall thickness of the sidewall portion 120, such as may be the average thickness of the sidewall portion 120. The thickness of the side wall 120 may be different or the same throughout. As shown in fig. 4, the thickness of the side wall portion 120 is uniform; as shown in fig. 7, the thickness of the sidewall portion 120 may gradually increase in a direction away from the body portion 110. In the present application, the manner of changing the thickness of the side wall portion 120 is not particularly limited.
The thickness of the side wall 120 is relatively thicker, and a structure matched with the main board and the display screen assembly 200 can be arranged on the inner side of the side wall 120, so that the main board and the display screen assembly 200 are directly arranged on the side wall 120, and the structure of the mobile phone is simpler. In addition, the thicker sidewall 120 is convenient for providing various shapes, such as the different shapes of the sidewall 120 in fig. 4 and 7. The thickness of the body portion 110 is very thin and the main area on the housing 100 is the body portion 110, which allows the housing 100 to be relatively light in weight and dissipate heat quickly.
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 housing 100 by vapor deposition to form a decorative layer, and in other alternative embodiments, ink may be sprayed on the inner surface of the housing 100, or a film may be adhered on the inner surface of the housing 100 to form a decorative layer. If the decorative layer is black, the internal structure of the mobile phone is prevented from being seen through the casing 100, and the side wall portion 120 and the main body portion 110 have a more integrated visual effect. Of course, patterns can be arranged on the decorative layer, so that the aesthetic property of the mobile phone rear shell is enhanced.

step b, laying glass fiber on the female die 320, and closing the die;
and c, heating and pressurizing the mold to obtain the shell 100 comprising the main body part 110 and the side wall part 120, wherein the thickness of the side wall part 120 is larger than that of the main body part 110.
As shown in fig. 8, 10 and 11, in one embodiment, the male mold 310 and the female mold 320 are clamped to form a cavity 330, and the shape and size of the cavity 330 are the same as those of the housing 100. The structure formed by the mold 300 is the same as the size of the housing 100 to be manufactured, and it can be understood that the housing 100 can be obtained by simple surface treatment, such as removing the flying edge, polishing, etc. The surfaces of the male die 310 and the female die 320 which are mutually attached after the die is clamped are parting surfaces, and the parting surfaces of the male die 310 and the female die 320 are flush with the end surface of the side wall portion 120, which is far from the main body portion 110. It will be appreciated that burrs and flashes on the product after the mold 300 is opened are located on the end surface of the side wall portion 120 remote from the main body portion 110, and polishing and deburring are performed only on the end surface of the side wall portion 120, with less influence on the smoothness of the outer surface of the housing 100.
As shown in fig. 8, in one embodiment, the punch 310 is provided with a vent hole 311. The vent hole 311 may be a straight through hole perpendicular to the surface of the male die 310, and the diameter may be 1.2-2.0 mm. Alternatively, the vent hole 311 may be designed as a stepped hole for ease of processing in order to avoid an elongated hole. When the vent hole 311 is a stepped hole, the part close to the parting surface of the male die 310 and the female die 320 is a small hole, and the part far from the parting surface is a large hole. The exhaust holes 311 are uniformly formed around the male mold 310, and the specific number thereof may be determined according to the actual size of the housing 100.
In another embodiment, as shown in fig. 9, the exhaust holes 311 are uniformly formed on the parting surface, one end of the exhaust holes communicates with the cavity 330, and the other end of the exhaust holes communicates with the atmosphere. It can be understood that the male die 310 is provided with a groove on the parting surface, the female die 320 is provided with another groove at the corresponding position of the groove, and when the die 300 is closed, the two grooves are combined to form the exhaust hole 311. In another embodiment, only the male mold 310 provides a recess in the parting plane, or only the female mold 320 provides a recess in the parting plane, for venting purposes.
The glass fibers are laid up over the matrix 320 and compacted such that the glass fibers fill the matrix 320. The mold 300 is clamped, placed on a hot press apparatus, heated and pressurized to above 680 ℃ to melt glass fibers, and then cooled slowly to obtain the shell 100 with burrs.
In one embodiment, the article obtained in step c is further processed, including sanding and polishing the burrs on the outer surface of the article, so that its shape meets the requirements of the desired housing 100. The article is polished to provide a smooth, transparent shell 100. A film may then be formed on the inner surface of the housing 100 by vapor deposition to serve as a decorative layer, and in other alternative embodiments, ink may be sprayed on the inner surface of the housing 100, or a film may be adhered to the inner surface of the housing 100 to form a decorative layer. If the decorative layer is black, the internal structure of the mobile phone is prevented from being seen through the casing 100, and the side wall portion 120 and the main body portion 110 have a more integrated visual effect. Of course, patterns can be arranged on the decorative layer, so that the aesthetic property of the mobile phone rear shell is enhanced.
The thickness of the glass shell obtained by the hot bending method is the same everywhere, namely, the thickness of the glass of the bent side wall part is equal to that of the glass of the straight plate part. By the technical scheme of the application, the glass fiber is sintered in a die to obtain the shell 100. The method greatly reduces the manufacturing difficulty and cost of the shell 100, the thickness of the main body 110 of the shell 100 is smaller than that of the side wall 120, the curve of the shell is attractive, the three-dimensional effect is strong, the aesthetic feeling and the hand feeling of the shell are improved, the outer surface of the shell 100 is smooth, and the user experience is good.
