At the same time, a through hole 202 may be provided on the side of the middle frame 211 away from the accommodation space 201, so that the accommodation space 201 can be connected to the outside of the housing 210 through the through hole 202 to maintain the air pressure balance inside and outside the accommodation space 201. In addition, a waterproof breathable membrane 220 is provided on the side of the middle frame 211 away from the accommodation space 201, and covers the through hole 202 to ensure the waterproof performance of the electronic device 10. In this embodiment, the middle frame 211 and the rear housing 212 may be an integral structure or an independent structure, and are assembled by methods such as bonding, welding or clamping. It is understandable that when the electronic device 10 is a device other than a mobile phone, the shape and structure of the housing 210 can also be adaptively adjusted according to needs, and this embodiment does not limit this.

[0028] Optionally, in some embodiments, the through hole 202 can be provided on the middle frame 211 or on the back cover 212. The specific location of the through hole 202 can be adaptively adjusted according to the design requirements of the housing 210. The through hole 202 only needs to connect the accommodating space 201 and the outside of the housing 210. This embodiment does not limit this. The waterproof breathable membrane 220, the isolation sheet 230, and the decorative member 240 are described below by taking the middle frame 211 having the through hole 202 as an example.

[0029] Optionally, in order to facilitate the decorative element 240 to cover the waterproof breathable membrane 220 and the isolation sheet 240 to improve the appearance refinement of the electronic device 10, a mounting groove 2111 for accommodating the waterproof breathable membrane 220 and the isolation sheet 240 is further provided on the side of the middle frame 211 away from the accommodating space 201. Figures 4 to 5As shown, the mounting groove 2111 can be used to mount the waterproof breathable membrane 220 and the isolation sheet 230, and the through hole 202 can be opened on the bottom wall of the mounting groove 2111 and penetrate the middle frame 211 to communicate with the accommodating space 201. The waterproof breathable membrane 220 can be arranged on the bottom wall of the mounting groove 2111 and cover the opening formed by the through hole 202 on the bottom wall of the mounting groove 2111 to reduce the probability of liquid entering the accommodating space 201 through the through hole 202. The isolation sheet 230 is arranged on the side of the waterproof breathable membrane 220 away from the bottom wall of the mounting groove 2111, and the isolation sheet 230 can be completely located in the mounting groove 2111, or a part of the area can be protruded from the mounting groove 2111. The decorative component 240 can be disposed on a side of the middle frame 211 away from the accommodating space 201 and can cover the mounting groove 2111 to conceal the waterproof breathable membrane 220 and the isolation sheet 240 in the mounting groove 2111, thereby improving the aesthetics of the electronic device 10.

[0030] Optionally, a plurality of through holes 202, such as 2, 3, 4, 5 or more, may be provided on the bottom wall of the mounting groove 2111. Of course, in some embodiments, the number of through holes 202 may also be single. In addition, the through hole 202 may not be limited to a circular hole, and the shape of the through hole 202 may also be adaptively adjusted according to design requirements. For example, the shape of the through hole 202 may also be a square, a rectangle, a triangle or a trapezoid, etc., which is not limited in the present embodiment. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] Optionally, in order to improve the flatness of the outer surface of the middle frame 211, that is, the surface of the middle frame 211 away from the accommodation space 201, a receiving groove 2112 for receiving the decorative member 240 may be provided on the side of the middle frame 211 away from the accommodation space 201. Figures 4 to 5 As shown, the shape of the receiving groove 2112 can match the shape of the decorative element 240, and the decorative element 240 can be installed on the bottom wall of the receiving groove 2112, and can cover the installation groove 2111 opened on the bottom wall of the receiving groove 2112. At the same time, the side of the decorative element 240 away from the bottom wall of the receiving groove 2112 can be flush with the surface of the middle frame 211 away from the receiving space 201, so as to improve the flatness of the outer surface of the middle frame 211. In addition, a glue point groove 2113 can be opened on the bottom wall of the receiving groove 2112, so that the decorative element 240 can be fixed in the receiving groove 2112 by the glue contained in the glue point groove 2113, so as to avoid directly dispensing glue on the receiving groove 2112 and causing the glue to flow into the installation groove 2111. Of course, in addition to fixing the decorative element 240 by bonding, the decorative element 240 can also be fixed by other assembly methods such as snap-on, screw connection and interference fit.

[0032] Optionally, in some embodiments, the design of the mounting groove 2111 and the receiving groove 2112 may also be omitted. The waterproof breathable membrane 220 may also be directly disposed on the side of the middle frame 211 away from the receiving space 201, and cover the opening of the through hole 202 formed on the side of the middle frame 211 away from the receiving space 201. At the same time, the decorative member 240 may also be directly disposed on the side of the middle frame 211 away from the receiving space 201, and cover the waterproof breathable membrane 220 and the isolation sheet 230 to isolate the waterproof breathable membrane 220 and the isolation sheet 230 from the influence of the external environment.

[0033] Please combine Figure 4 See also Figures 6 to 8 , Figure 6 yes Figure 4 The schematic diagram of the structure of the waterproof breathable membrane 220, Figure 7 yes Figure 4 A schematic diagram of the structure of the middle isolation sheet 230, Figure 8 yes Figure 4 A schematic structural diagram of the middle decorative element 240.

[0034] For example, the waterproof and breathable membrane 220 may be disposed on the bottom wall of the mounting groove 2111 and cover the opening of the through hole 202 formed on the mounting groove 2111. Figure 4 and Figure 6 As shown, the waterproof breathable membrane 220 may include: a flexible portion 221 and a rigid portion 222. The rigid portion 222 is provided on opposite sides of the flexible portion 221, and the central areas of the rigid portions 222 on opposite sides may be provided with through grooves 2221 connected to the flexible portion 221, so that the partial surfaces of the flexible portion 221 on opposite sides may be exposed on the side of the rigid portion 222 away from the flexible portion 221 through the through grooves 2221. At the same time, the flexible portion 221 may have waterproof breathability, and the exposed partial surfaces of the flexible portion 221 on opposite sides may be connected to the through hole 202 and the first breathable hole 203, respectively, so that the flexible portion 221 can block the liquid entering the through hole 202 from the first breathable hole 203 while playing a breathable role. In addition, the rigid parts 222 located on opposite sides of the flexible part 221 can support and fix the flexible part 221 to reduce the probability of wrinkles or deviations of the flexible part 221, and the rigid parts 222 on opposite sides can be respectively connected to the bottom wall of the mounting groove 2111 and the isolation sheet 230 to improve the connection firmness between the waterproof breathable membrane 220 and the middle frame 211 and the isolation sheet 230. For example, the surface of the rigid part 222 away from the flexible part 221 can be provided with adhesive, so that the rigid part 222 can be bonded and fixed to the bottom wall of the mounting groove 2111, and the isolation sheet 230 can also be bonded and fixed to the rigid part 222.

[0035] Optionally, in some embodiments, the waterproof breathable membrane 220 may not be limited to the configuration of the aforementioned embodiments, and its specific structure may be adaptively adjusted according to design requirements. It is only necessary that the waterproof breathable membrane 220 can cover the through hole 202 and play a waterproof and breathable role. This embodiment does not limit this.

[0036] The isolation sheet 230 is disposed on the side of the waterproof breathable membrane 220 away from the bottom wall of the installation groove 2111, and the isolation sheet 230 may also be provided with a first vent hole 203 connected to the waterproof breathable membrane 220. Figure 4 and Figure 7 As shown, the isolation sheet 230 can be covered on the side of the rigid part 222 away from the flexible part 221, and the first air hole 203 can be opened on the side of the isolation sheet 230 away from the flexible part 221, and penetrate the isolation sheet 230 in the direction close to the flexible part 221 to communicate with the through groove 2221, so as to achieve the communication between the first air hole 203 and the flexible part 221. At the same time, the isolation sheet 230 can be made of a material such as a metal or hard plastic with high hardness, such as a steel sheet or a plastic sheet, so that the isolation sheet 230 can play a role in protecting the waterproof breathable membrane 220, so as to avoid the problem that the user mistakenly inserts the card removal needle into the second light transmission hole 204, resulting in the waterproof breathable membrane 220 being punctured. In addition, the shape of the isolation sheet 230 can match the flexible part 221, so that the decorative member 240 can cover the isolation sheet 230 and the waterproof breathable membrane 220 at the same time.

[0037] Optionally, in order to maximize the use of the channel 205 to extend the path for liquid and dust to enter the first air hole 203, the first air hole 203 can be opened in the area of ​​the isolation sheet 230 away from the second air hole 204. At the same time, the number of the first air holes 203 can also be multiple, and the multiple first air holes 203 can also be concentrated in the area of ​​the isolation sheet 230 away from the second air hole 203 to reduce the probability of liquid and dust entering the first air hole 203.

[0038] The decorative member 240 is disposed on the side of the middle frame 211 away from the accommodating space 201, and can cover the isolation sheet 230 and the waterproof breathable membrane 220 to protect the isolation sheet 230 and the waterproof breathable membrane 220, and can improve the aesthetics of the electronic device 10. Figure 4 and Figure 8As shown, the decorative member 240 is arranged in the receiving groove 2112, and is covered on the bottom wall of the receiving groove 2112, and can cover the waterproof breathable membrane 220 and the isolation sheet 230 located in the mounting groove 2111. At the same time, the decorative member 240 can be fixed in the receiving groove 2112 by adhesive bonding in the glue dispensing groove 2113, and the shape of the decorative member 240 can also match the shape of the receiving groove 2112 to reduce the gap between the decorative member 240 and the middle frame 211 (the side wall of the receiving groove 2112). In addition, the material of the decorative member 240 can match the material of the middle frame 211 to improve the appearance consistency of the housing assembly 200, and the side of the decorative member 240 away from the bottom wall of the receiving groove 2112 is preferably flush with the outer surface of the middle frame 211 away from the receiving space 201 to improve the flatness of the outer surface of the housing 210.

[0039] Optionally, a second vent hole 204 is provided on the side of the decorative member 240 facing away from the isolation sheet 230, and the second vent hole 204 can penetrate the decorative member 240 in the direction of the decorative member 240 approaching the isolation sheet 230, so as to communicate with the channel 205 between the decorative member 240 and the isolation sheet 230. The opening directions of the first vent hole 203 and the second vent hole 204 can be parallel, and the second vent hole 204 can be provided in the area of ​​the decorative member 240 away from the first vent hole 203, so as to maximize the use of the channel 205 to extend the path for liquid and dust to enter the first vent hole 203.

[0040] Optionally, in some embodiments, the second vent hole 204 may not be limited to being provided on the side of the decorative member 240 facing away from the isolation sheet 230. For example, the second vent hole 204 may also be provided on the side surface of the decorative member 240 facing the side wall of the receiving groove 2112, and the second vent hole 204 may be composed of two connected blind holes. That is, a blind hole may be provided on the surface of the decorative member 240 facing the side wall of the receiving groove 2112, and another blind hole may be provided on the side of the decorative member 240 facing the isolation sheet 230, and one end of the two blind holes located in the decorative member 240 may be connected. At the same time, the surface of the decorative member 240 facing the side wall of the receiving groove 2112 may be designed with a certain spacing from the side wall of the receiving groove 2112 to prevent the opening of the second vent hole 204 formed on the side surface of the decorative member 240 from being covered.

[0041] Optionally, the side of the decorative member 240 facing the isolation sheet 230 may be recessed in a direction away from the isolation sheet 230, so as to form the aforementioned channel 205 between the decorative member 240 and the isolation sheet 230. The extension direction of the channel 205 may be perpendicular to the opening direction of the first air hole 203 and the second air hole 204, and in order to maximize the use of the channel 205 to extend the path for liquid and dust to enter the first air hole 203, the first air hole 203 and the second air hole 204 are preferably connected to the opposite ends of the channel 205 in the extension direction, so that liquid and dust need to pass through the entire channel 205 before they can enter the first air hole 203, so as to reduce the probability of liquid and dust accumulating on the waterproof breathable membrane 220 and causing the first air hole 203 to be blocked.

[0042] Of course, in some embodiments, the channel 205 may not be limited to being formed by a recessed setting of the decorative member 240 toward the side of the isolation plate 230, and the channel 205 may also be designed to be tortuous to further extend the path of the channel 205. It is only necessary that a channel 205 connecting the first air hole 203 and the second air hole 204 can be formed between the decorative member 240 and the isolation plate 230, and the channel 205 can serve to extend the path for liquid and dust to enter the first air hole 203.

[0043] Optionally, the strap assembly 300 is connected to the side surface of the middle frame 211 away from the accommodating space 201, and can be detachably connected to the middle frame 211. For example, the strap assembly 300 may include: a strap and an ear pin connected to the end of the strap.
