[0033] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the drawings.

[0034] To meet the requirements of waterproof and dustproof, the interior of an electronic device is usually relatively airtight. To balance the pressure inside and outside the electronic device, air vents are usually provided on the outer shell of the electronic device and are connected to the interior of the electronic device.

[0035] As Figure 1 and Figure 2 shown, in a traditional electronic device, an air vent 101 is provided on the outer wall of the outer shell 100, and a waterproof and breathable membrane 200 covers the interior of the outer shell 100 and is located between the screen assembly 300 and the outer shell 100. The opening of the air vent 101 can be observed by the user with the naked eye on the electronic device, which not only affects the aesthetics of the electronic device, but also requires precision machining of computer digital control for the air vent 101, increasing the production cost.

[0036] To solve the technical problems existing in the prior art, as Figure 3 and Figure 4 shown, an embodiment of the present application provides a shell assembly 1, and the shell assembly 1 includes a rear cover 11, a housing 12, and a waterproof and breathable membrane 13.

[0037] The shell assembly 1 is applied to an electronic device, and the electronic device includes but is not limited to a mobile phone, a tablet computer, a notebook computer, a wearable device, a virtual reality device, etc.

[0038] The rear cover 11 is installed on one side of the housing 12, and there is a gap 14 between the outer peripheral surface of the rear cover 11 and the housing 12.

[0039] An installation space 121 is provided inside the housing 12, and an air release channel 1221 is provided on the side wall 122 of the housing 12. The air release channel 1221 is respectively connected to the gap 14 and the installation space 121. The waterproof and breathable membrane 13 is connected to the housing 12, and the waterproof and breathable membrane 13 is used to prevent water from flowing into the installation space 121 through the air release channel 1221.

[0040] Specifically, the installation space 121 is used to accommodate relevant components of the electronic device, such as a main board, a circuit board, an audio component, etc.

[0041] The rear cover 11 and the screen assembly 2 are respectively installed on both sides in the thickness direction of the housing 12, that is, the rear cover 11 and the screen assembly 2 are arranged opposite to each other along the thickness direction of the housing 12. As Figure 4 shown, the thickness direction of the housing 12 is parallel to the vertical direction.

[0042] The outer peripheral surface of the rear cover 11 is spaced from the housing 12, and a gap 14 is formed on at least one side of the rear cover 11. For example, the rear cover 11 is generally rectangular, and the four outer peripheral surfaces of the rear cover 11 are all spaced from the housing 12, and the gap 14 is annular and surrounds the outside of the rear cover 11.

[0043] Exemplarily, the housing 12 is generally in the shape of a rectangular plate, and the housing 12 has four side walls 122. The four side walls 122 enclose a ring shape, and the installation space 121 is located within the space enclosed by the four side walls 122. One end of the air leakage channel 1221 communicates with the gap 14, and the other end communicates with the installation space 121.

[0044] The waterproof and breathable film 13 can allow air to pass through and block liquid. Exemplarily, the waterproof and breathable film 13 covers one end of the air leakage channel 1221 close to the installation space 121, so that the gas in the air leakage channel 1221 can pass through the waterproof and breathable film 13 and enter the installation space 121, and the gas in the installation space 121 can also pass through the waterproof and breathable film 13 and enter the air leakage channel 1221, thereby balancing the air pressure inside and outside the electronic device and preventing the components inside the electronic device from being damaged due to unbalanced internal and external air pressures.

[0045] Exemplarily, the waterproof and breathable film 13 is adhered to the side wall 122 of the housing 12 to improve the installation stability and reliability of the waterproof and breathable film 13.

[0046] Exemplarily, the housing 12 is an injection molded part, that is, the housing 12 is made by an injection molding process. The air leakage channel 1221 is located inside the housing 12. When the housing assembly 1 is assembled in the electronic device, the user cannot observe the air leakage channel 1221 with the naked eye.

[0047] For the housing assembly 1 provided by the embodiment of the present application, by opening the air leakage channel 1221 on the side wall 122 of the housing 12, and the air leakage channel 1221 is respectively connected to the gap 14 and the installation space 121, the gap 14 between the outer peripheral surface of the rear cover 11 and the housing 12 is used to connect the inside and outside of the electronic device. There is no need to additionally open an air vent hole 101 on the outer wall of the housing 12. The housing 12 can be directly formed by a mold, saving production costs, improving the aesthetics of the electronic device, and being beneficial to enhancing the user experience; by arranging the waterproof and breathable film 13 between the air leakage channel 1221 and the installation space 121, while ensuring the passage of gas, it prevents water from entering the installation space 121 and damaging the components, achieving the effects of air permeability and waterproofing.

[0048] In a further embodiment, a flange 1222 protrudes from the surface of the side wall 122 of the housing 12 facing the rear cover 11. The flange 1222 is annular and surrounds the circumferential side of the rear cover 11. The outer peripheral surface of the rear cover 11 is spaced apart from the flange 1222 to form the gap 14.

[0049] As Figure 3 and Figure 4 shown, the flange 1222 is connected to the side wall 122 of the housing 12, and the flange 1222 is located above the side wall 122 of the housing 12. There is a gap between the outer peripheral surface of the rear cover 11 and the flange 1222, and the top surface of the side wall 122 of the housing 12 bears the rear cover 11.

[0050] In this embodiment, the gap 14 is annular and surrounds the outer side of the rear cover 11.

[0051] In one embodiment, there are a plurality of air leakage channels 1221 and waterproof breathable membranes 13. The plurality of air leakage channels 1221 are arranged in one-to-one correspondence with the plurality of waterproof breathable membranes 13.

[0052] Specifically, each air leakage channel 1221 is respectively communicated with the gap 14 and the installation space 121. The plurality of air leakage channels 1221 are distributed at intervals along the circumferential direction of the housing 12. Moreover, a waterproof breathable membrane 13 is covered between each air leakage channel 1221 and the installation space 121.

[0053] In this embodiment, by setting that there are a plurality of air leakage channels 1221 and waterproof breathable membranes 13, the gas outside the electronic device can enter the installation space 121 along multiple channels, and when there is a pressure difference between the inside and outside of the electronic device, the air pressure can be quickly balanced, improving the air pressure adjustment efficiency of the electronic device.

[0054] In one embodiment, a receiving groove 1223 is recessed on the inner side surface of the housing 12. The air leakage channel 1221 opens at the bottom of the receiving groove 1223, and the waterproof breathable membrane 13 is covered on the bottom of the receiving groove 1223.

[0055] It can be understood that the inner side surface of the housing 12 is the surface of the side wall 122 close to the installation space 121. The bottom of the receiving groove 1223 is the side away from the installation space 121 of the receiving groove 1223, and the air leakage channel 1221 is communicated with the bottom of the receiving groove 1223.

[0056] As Figure 3 shown, a rectangular receiving groove 1223 is recessed on the inner side surface of the side wall 122 of the housing 12. The size and shape of the receiving groove 1223 are respectively adapted to the size and shape of the waterproof breathable membrane 13.

[0057] Among them, the fact that the size of the receiving groove 1223 is adapted to the size of the waterproof breathable membrane 13 means that the size of the receiving groove 1223 is the same as the size of the waterproof breathable membrane 13, or the size of the receiving groove 1223 is slightly larger than the size of the waterproof breathable membrane 13. The fact that the shape of the receiving groove 1223 is adapted to the shape of the waterproof breathable membrane 13 means that the shape of the receiving groove 1223 is the same as the shape of the waterproof breathable membrane 13. For example Figure 3 shown, both the receiving groove 1223 and the waterproof breathable membrane 13 are rectangular.

[0058] In this embodiment, by providing the receiving groove 1223, an installation position is provided for the waterproof breathable membrane 13, which is conducive to quickly carrying out installation positioning when assembling the waterproof breathable membrane 13.

[0059] The air release channel 1221 includes a connected first section 1221a and a second section 1221b. One end of the first section 1221a away from the second section 1221b is in communication with the gap 14, and one end of the second section 1221b away from the first section 1221a is in communication with the installation space 121. There is an included angle between the first section 1221a and the second section 1221b.

[0060] Specifically, the opening of the first section 1221a is located on the top surface of the side wall 122 of the housing 12, and the opening of the second section 1221b is located on the inner surface of the side wall 122 of the housing 12. Both the first section 1221a and the second section 1221b extend in a straight line, and there is an included angle between the extension line of the first section 1221a and the extension line of the second section 1221b. The specific angle of the included angle can be set according to actual needs, and the present application does not make specific limitations.

[0061] Optionally, the air release channel 1221 may also extend in an arc.

[0062] In a further embodiment, the first section 1221a extends along the thickness direction of the housing 12, and the extension direction of the second section 1221b is perpendicular to the extension direction of the first section 1221a.

[0063] As Figure 4 shown, the first section 1221a extends in the vertical direction, the second section 1221b extends in the horizontal direction, and the extension direction of the first section 1221a is perpendicular to the extension direction of the second section 1221b.

[0064] Furthermore, one end of the second section 1221b away from the installation space 121 extends beyond the intersection of the first section 1221a and the second section 1221b.

[0065] As Figure 4 shown, in this embodiment, the end face of one end of the second section 1221b away from the installation space 121 is not flush with the side wall surface of the first section 1221a. The end face of one end of the second section 1221b away from the installation space 121 is located on the left side of the first section 1221a, that is, the second section 1221b extends outward by a certain distance relative to the first section 1221a. The space formed thereby can play a certain buffering role for the liquid entering the air release channel 1221.

[0066] In one embodiment, the rear cover 11 is bonded to the housing 12 by a waterproof adhesive.

[0067] Specifically, as Figure 4 shown, the rear cover 11 is bonded to the top surface of the side wall 122 of the housing 12 by a waterproof adhesive, which plays a waterproof role while ensuring the connection strength between the rear cover 11 and the housing 12.

[0068] The embodiment of the present application further provides an electronic device, including the housing assembly 1 provided in any of the above embodiments.
