[0023] The present disclosure provides a housing, a housing assembly and an electronic device. The housing, the housing assembly and the electronic device are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.
[0024] refer to Figure 1 As shown, the embodiment of the present disclosure provides a housing, including a battery cover body 10 and a decorative structure 20, the decorative structure 20 and the battery cover body 10 are stacked, the battery cover body 10 and the decorative structure 20 are integrally formed, and the material of the battery cover body 10 and the decorative structure 20 is glass fiber material. Among them, the decorative structure 20 can be used to decorate the camera assembly of the electronic device, but is not limited thereto.
[0025] The battery cover body 10 and the decorative structure 20 are integrally formed, so that the battery cover body 10 and the decorative structure 20 form a whole, so that the appearance of the entire shell is more integrated and exquisite, and the sense of separation between the battery cover body 10 and the decorative structure 20 is reduced. In addition, the integral molding of the battery cover body 10 and the decorative structure 20 can also improve the overall strength of the shell and the sealing performance between the decorative structure 20 and the battery cover body 10. In addition, the glass fiber material has the characteristics of light weight, high strength, corrosion resistance, insulation and high temperature resistance, and it already has the V0 fire protection requirements limited by relevant specifications. Compared with the shell formed by the current mainstream PC injection molding scheme to meet the V0 fire protection level, the plastic thickness is greater than 0.7mm, and the fireproof ink is added at the same time. There are many requirements for the plastic wall thickness in terms of processability (too small cannot be molded, too large will cause shrinkage). In addition, due to the high temperature of plastic injection molding, there is a risk of deformation after molding, and the defective rate is high. At the same time, the mold structure is simple, and the design change during the design process requires a long mold repair time. Therefore, the shell made of glass fiber material in the present disclosure has a good fire protection level while ensuring lightness.
[0026] In one embodiment, the battery cover body 10 includes at least one layer of glass fiber cloth 30, the decorative structure 20 includes at least one layer of glass fiber cloth 30, and the battery cover body 10 and the decorative structure 20 are compressed and molded as one. Specifically, the glass fiber cloth 30 can be formed by a composite of glass fiber materials, and the glass fiber cloth 30 of the battery cover body 10 and the glass fiber cloth 30 of the decorative structure 20 are integrally formed by a hot pressing process at 180°C in a hot press. In other words, the battery cover body 10 is a battery cover glass fiber board composed of at least one layer of glass fiber cloth 30, and the decorative structure 20 is a decorative structure 20 glass fiber board composed of at least one layer of glass fiber cloth 30. The battery cover glass fiber board and the decorative structure 20 glass fiber board are integrally compressed and molded by a hot pressing process. The shell formed by directly hot pressing the battery cover body 10 and the decorative structure 20 body does not have appearance quality problems such as gaps and wall climbing, which effectively improves the appearance integrity and reliability of the shell.
[0027] like Figure 2 In the embodiment shown, the battery cover body 10 includes 4 layers of glass fiber cloth 30, and the decorative structure 20 includes a first portion located outside the battery cover body 10 and a second portion located inside the battery cover body 10; wherein the first portion includes 4 layers of glass fiber cloth 30, and the second portion includes 2 layers of glass fiber cloth 30, but is not limited thereto. For example, in some other embodiments, the battery cover body 10 may include multiple layers of glass fiber cloth 30 other than 4 layers, and the decorative structure 20 may include a plurality of layers other than the attached Figure 2 The number and arrangement of multiple layers of glass fiber cloth 30 are shown. For example, the battery cover body 10 may include 2, 3, or 5 layers of glass fiber cloth 30, the first part may include 2, 3, or 5 layers of glass fiber cloth 30, and the second part may include 0, 1, 3, or 4 layers of glass fiber cloth 30, but are not limited thereto.
[0028] In one embodiment, the thickness of the glass fiber cloth 30 is greater than or equal to 0.1 mm. It is easy to understand that when the thickness of the glass fiber cloth 30 is greater than or equal to 0.1 mm, the processability of the glass fiber cloth 30 can be satisfied. Therefore, the thickness of the glass fiber cloth 30 is set to be greater than or equal to 0.1 mm in this solution, which can give the battery cover body 10 and the decorative structure 20 sufficient design freedom.
[0029] The embodiment of the present disclosure further provides a housing assembly, comprising the housing described in any of the above embodiments. That is, any description of the housing described above is applicable to the housing assembly.
[0030] The shell assembly also includes an outer cover 40 and a decorative sheet 50. The outer cover 40 is arranged on the outside of the battery cover body 10 to cover the battery cover body 10. The outer cover 40 has a through hole 41 corresponding to the decorative structure 20. The decorative sheet 50 is arranged on the outside of the decorative structure 20 through the through hole 41. The outer cover 40 and the decorative sheet 50 are made of the same material. It is easy to understand that the outer cover 40 and the decorative sheet 50 are located on the outside of the entire shell assembly and directly contact the user. Therefore, the outer cover 40 and the decorative sheet 50 are set to the same material, so that the outer surface of the shell assembly is more integrated and the feel of the shell assembly is improved.

The housing assembly is made more beautiful by setting the color, shape, texture, etc. of the decorative ring 60 to decorate the mounting boss 21. The decorative ring 60 may be made of metal, but is not limited thereto.
[0035] In one embodiment, the decorative sheet 50 further includes a boss hole 51 corresponding to the mounting boss 21, and the mounting boss 21 further extends out of the boss hole 51. The housing assembly further includes a decorative lens 70, which is attached to the outer end of the mounting boss 21 to further decorate the appearance of the housing assembly. The decorative lens 70 can add a unique appearance effect through its material, color, texture and other characteristics, thereby enhancing the overall visual appeal of the housing assembly.
[0036] like Figure 1 In the embodiment shown, four mounting bosses 21 are provided, and the four mounting bosses 21 are distributed in an array, and four decorative rings 60 and decorative lenses 70 are also provided accordingly. It is easy to understand that the sizes of the four mounting bosses 21 can be consistent or different, and the embodiment of the present disclosure does not impose specific restrictions on this. Of course, in some other embodiments, the number of mounting bosses 21, decorative rings 60 and decorative lenses 70 can also be multiple other than four.
[0037] In one embodiment, please continue to refer to Figure 1 The shell also includes a buffer strip disposed on the inner side of the shell, and the buffer strip is used to contact the internal structure of the electronic device. The shell may be subjected to external impact or collision during use, and these impact forces will be transmitted to the internal structure and battery of the electronic device.
