[0030] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0031] When an electronic device enters a low-pressure environment from a high-pressure environment, the pressure inside the electronic device is greater than the external pressure. The internal pressure of the electronic device needs to be released to avoid certain safety risks in the use of the electronic device.

[0032] In the related art, corresponding ventilation holes are often opened on the surface of the housing of electronic equipment. There are currently two common methods:

[0033] One is to make holes in the side wall of the housing, and to set holes that penetrate the electronic equipment and independent waterproof and breathable devices to achieve waterproof, sound-permeable and breathable functions. However, the device is relatively complex, difficult to disassemble, and has a high cost, and affects the overall appearance of the electronic equipment.

[0034] The second is to open a hole on the screen side of the front of the shell, and cooperate with the dustproof net assembly to prevent liquid and dust from entering the electronic device through the mesh. However, this kind of opening is large, and holes need to be opened in the middle frame and the screen, which is costly and affects the screen-to-body ratio and the refinement of the whole machine.

[0035] However, the above-mentioned vent holes are opened on the surface of the shell, which seriously affects the overall shape of the electronic device, and the refinement of the whole device is poor, and cannot meet the user's requirements for high refinement of the product appearance.

[0036] In order to solve the above technical problems, the present disclosure provides a housing assembly and an electronic device.

[0037] According to a first aspect of the present disclosure, a housing assembly is provided. Figure 1-5 As shown, a shell assembly includes: a middle frame 10 and a shell 20.

[0038] The middle frame 10 has an installation cavity 11, which is used to install electronic components. A ventilation channel 12 is provided inside the middle frame 10, and one end of the ventilation channel 12 is connected to the installation cavity 11; the shell 20 is arranged on the side of the middle frame 10 facing the installation cavity 11, and the shell 20 and the middle frame 10 enclose and define an assembly gap 13, which is connected to the outside, and the other end of the ventilation channel 12 is connected to the assembly gap 13.

[0039] It is understandable that the electronic components may be a mainboard, a circuit board, a battery, an earpiece, a speaker or a combination thereof, and the present disclosure does not specifically limit this.

[0040] The middle frame 10 can be made of metal, plastic, ceramic, glass and other materials, has high structural strength, and is used to support and protect the electronic equipment.

[0041] The shell 20 can be the shell of wearable devices such as smart watches, smart bracelets, smart rings, VR (Virtual Reality) headsets, such as the battery back cover of a mobile phone, or the shell of other electronic devices with waterproof requirements such as locators, walkie-talkies, mobile phones, tablets, etc.

[0042] The ventilation channel 12 is located inside the middle frame 10 and is a channel connecting the inside of the electronic device with the outside, and is used to balance the air pressure inside the electronic device with the outside.

[0043] The assembly gap 13 is an assembly gap between the housing 20 and the middle frame 10 .

[0044] The present invention opens a ventilation channel 12 inside the middle frame 10 to connect the assembly gap 13 and the installation cavity 11, thereby avoiding opening holes on the outer wall of the middle frame 10 or the front of the shell 20, thereby achieving ventilation of the entire device while avoiding affecting the overall shape of the electronic device, improving the overall appearance refinement of the electronic device, meeting users' requirements for high refinement of product appearance, and further enhancing the market competitiveness of electronic products.

[0045] In some embodiments, Figure 3-5 As shown, the middle frame 10 has a bottom wall 101 and a side wall 102. The side wall 102 is arranged around the bottom wall 101. The air permeable channel 12 is opened on the side of the side wall 102 facing the shell 20. The shell 20 and the side wall 102 are enclosed to define an assembly gap 13. The shell 20, the bottom wall 101 and the side wall 102 are enclosed to define an installation cavity 11.

[0046] The bottom wall 101 and the side wall 102 may be an integral structure or two independent components. The bottom wall 101 and the side wall 102 are fixedly connected to define the middle frame 10 .

[0047] In the embodiment of the present disclosure, a ventilation channel 12 is opened inside the middle frame 10, and the ventilation channel 12 is opened on the side of the side wall 102 facing the shell 20. The shell 20 and the side wall 102 are enclosed to define an assembly gap 13. The shell 20, the bottom wall 101, and the side wall 102 are enclosed to define an installation cavity 11. The ventilation channel 12 connects the assembly gap 13 and the installation cavity 11, thereby avoiding opening holes on the outer wall of the middle frame 10 or the front of the shell 20, thereby achieving ventilation of the entire machine while avoiding affecting the overall shape of the electronic device, thereby improving the overall appearance refinement of the electronic device.

[0048] In some embodiments, Figure 3-5 As shown, the air permeable channel 12 is opened on the side wall 102 along the thickness direction of the middle frame 10 .

[0049] The air permeable channel 12 may be a straight channel or an oblique channel, and the radial cross-sectional shape of the channel may also be set as required, for example, it may be circular, square, diamond, triangle, elliptical, rectangular, etc.

[0050] In the embodiment of the present disclosure, a ventilation channel 12 is opened inside the side wall 102 of the middle frame 10 along the thickness direction of the middle frame 10, the ventilation channel 12 is opened on the side of the side wall 102 facing the shell 20, the shell 20 and the side wall 102 are enclosed to define an assembly gap 13, the shell 20 and the bottom wall 101 and the side wall 102 are enclosed to jointly define an installation cavity 11, the ventilation channel 12 connects the assembly gap 13 and the installation cavity 11, and it is avoided to open a hole on the outer wall of the middle frame 10 or the front of the shell 20, so that the whole machine is ventilated, and the overall shape of the electronic device is avoided, thereby improving the overall appearance refinement of the electronic device.

[0051] In some embodiments, Figure 5 As shown, the side of the side wall 102 facing the shell 20 includes an assembly portion 1021 and a fixing portion 1022. The assembly portion 1021 is arranged around the fixing portion 1022. The assembly portion 1021 and the shell 20 together define an assembly gap 13. The fixing portion 1022 is fixedly connected to the shell 20 to separate the assembly gap 13 and the installation cavity 11.

[0052] In the embodiment of the present disclosure, the assembly part 1021 is assembled and positioned with the housing 20, and the assembly part 1021 and the housing 20 jointly define an assembly gap 13, the assembly gap 13 is communicated with the outside, and the air permeable channel 12 is communicated with the assembly gap 13. The fixing part 1022 is fixedly connected with the housing 20, for example, the housing 20 and the fixing part 1022 are fixed by adhesive backing, which can effectively prevent dust and water.

[0053] In some embodiments, Figure 6-7 As shown, the shell assembly further includes: a waterproof and breathable assembly 30.

[0054] The waterproof breathable component 30 is disposed at the connection between the breathable passage 12 and the installation cavity 11 .

[0055] It should be noted that the provision of the ventilation channel 12 will reduce the waterproof performance of the electronic device, and the electronic device is easily intruded by water, resulting in a shortened service life and even a safety risk. Therefore, a waterproof and breathable component 30 is required to achieve the purpose of waterproofing, dustproofing and balancing air pressure.

[0056] Exemplarily, the waterproof breathable component 30 includes a waterproof breathable membrane 31 and a bonding layer 32. Figure 7 As shown, an adhesive layer 32 is provided on the outer peripheral side of one side of the waterproof breathable membrane 31 , and the waterproof breathable membrane 31 is fixed at the connection between the breathable passage 12 and the installation cavity 11 through the adhesive layer 32 .

[0057] In the disclosed embodiment, the waterproof breathable membrane 31 can be made of polytetrafluoroethylene (PTFE) membrane, the membrane pore size can be controlled between 0.2 and 15 μm, and the porosity can reach more than 85%. The unique node fibrillation, smooth surface, chemical resistance, air permeability and water-tightness, large air permeability, flame retardancy, high temperature resistance, strong acid and alkali resistance, and non-toxicity of the polytetrafluoroethylene microporous membrane can achieve dustproof and IP68 waterproof effects.

[0058] The adhesive layer 32 can be a hot melt adhesive layer, and the waterproof breathable membrane 31 is bonded to the middle frame 10 through the hot melt adhesive layer. The hot melt adhesive layer is pressurized, heated and cured to achieve a close combination of the two. The bonding is simple and the maintenance is convenient. It can effectively avoid water leakage from the gaps in the bonding part, thereby achieving the purpose of waterproofing, dustproofing and balancing the air pressure.

[0059] In some embodiments, Figure 5-6 As shown, the side wall 102 is provided with a mounting groove 103 , and the waterproof breathable component 30 is embedded and fixed in the mounting groove 103 and covers the breathable channel 12 .

[0060] The mounting groove 103 is located at the connection between the air permeable channel 12 and the mounting cavity 11. The mounting groove 103 can be a rectangular groove structure, a circular groove structure, or a groove structure of other shapes, which is not specifically limited in the present disclosure.

[0061] In the disclosed embodiment, the mounting groove 103 is located on the side wall 102 of the middle frame 10. The side wall 102 can be in the length direction of the electronic device or in the width direction of the electronic device, thereby avoiding occupying the space in the thickness direction of the middle frame 10, that is, avoiding occupying the space in the thickness direction of the electronic device. Space in the thickness direction of the electronic device can be provided for other electronic components, thereby greatly improving space utilization.

[0062] In some embodiments, the housing assembly further includes: a first bonding member (not shown in the figures).

[0063] The first adhesive member is disposed between the fixing portion 1022 and the housing 20 , and the housing 20 and the middle frame 10 are fixedly connected via the first adhesive member.

[0064] The first adhesive member may be a hot melt adhesive, a polyurethane adhesive, or other adhesive members, and the embodiments of the present disclosure do not specifically limit this.

[0065] In the disclosed embodiment, the first adhesive member is arranged along the outer periphery of the housing 20 and avoids the air permeable channel 12 to prevent the first adhesive member from blocking the air permeable channel 12. The first adhesive member may be a hot melt adhesive, and the housing 20 and the fixing portion 1022 of the middle frame 10 are bonded and fixed by the first adhesive member. By pressurizing and heating the hot melt adhesive to cure, the housing 20 and the middle frame 10 are tightly combined, which can effectively prevent water leakage and dust ingress from the gap of the bonding portion, thereby effectively preventing dust and water.

[0066] In some embodiments, Figure 6 As shown, the air permeable channel 12 may include an air guiding channel 40 .

[0067] In the present disclosure, the air guide channel 40 may be an end of the air permeable channel 12, for example, an end of the air permeable channel 12 that is connected to the installation cavity 11. For example, the air permeable channel 12 is connected to the installation cavity 11 through the air guide channel 40, and the waterproof breathable component 30 may cover the air guide channel 40.

[0068] In the embodiment of the present disclosure, one scenario is that the air guide channel 40 is located inside the middle frame 10, which can avoid opening holes on the outer wall of the middle frame 10 or the front of the shell 20. The waterproof and breathable component 30 covers the air guide channel 40 to achieve the purpose of waterproofing, dustproofing and balancing the air pressure, and realizes a hole-free top of the entire machine, greatly improving the exquisite appearance of the entire machine.

[0069] In one case, the air guide channel 40 is located inside the middle frame 10, and the air guide channel 40 and the other parts of the air permeable channel 12 may also be two independent parts. That is, the air permeable channel 12 may be composed of two parts, one part is the air guide channel, and the other part may be the connecting channel. The air guide channel 40 is fixedly connected to the connecting channel, one end of the air guide channel 40 is connected to the connecting channel, and the other end of the air guide channel 40 is connected to the installation cavity 11, avoiding opening holes on the outer wall of the middle frame 10 or the front of the shell 20. The waterproof and breathable component 30 covers the air guide channel 40, achieving the purpose of waterproof and dustproof and balanced air pressure, realizing the top of the whole machine without holes, and greatly improving the appearance refinement of the whole machine.

[0070] In some embodiments, Figure 6 As shown, the air guide channel 40 includes a first channel 41 and a second channel 42 .

[0071] The first channel 41 is arranged along a first direction, and the second channel 42 is arranged along a second direction which is different from the first direction. One end of the second channel 42 is connected to the other end of the first channel 41 , and the other end of the second channel 42 is connected to the installation cavity 11 .

[0072] The channel cross-section of the first channel 41 may be circular, rectangular, or other shapes.

[0073] The channel cross-section of the second channel 42 may be circular, rectangular, or other shapes; the channel cross-section of the first channel 41 may be the same as or different from the channel cross-section of the second channel 42, which is not specifically limited in the embodiment of the present disclosure.

[0074] In the disclosed embodiment, the first channel 41 and the second channel 42 can be an integral structure or two independent components. The first channel 41 and the second channel 42 are fixedly connected to avoid opening holes in the outer wall of the middle frame 10 or the front of the shell 20. The waterproof and breathable component 30 covers the air guide channel 40 to achieve the purpose of waterproofing, dustproofing and balancing air pressure, and realizes a hole-free top of the whole machine, which greatly improves the refined appearance of the whole machine.

[0075] Based on the same inventive concept, according to a second aspect of the present disclosure, there is provided an electronic device, comprising: a housing assembly as in any one of the embodiments of the first aspect described above.

[0076] It should be noted that the electronic device can be an electronic device equipped with a housing assembly, such as a mobile phone, a computer, a digital broadcast terminal, a message sending and receiving device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, etc.

[0077] In the present disclosure, a ventilation channel 12 is opened inside the middle frame 10, and the ventilation channel 12 is opened on the side of the side wall 102 facing the shell 20. The shell 20 and the side wall 102 are enclosed to define an assembly gap 13. The shell 20, the bottom wall 101, and the side wall 102 are enclosed to define an installation cavity 11. The ventilation channel 12 connects the assembly gap 13 and the installation cavity 11, avoiding opening holes on the outer wall of the middle frame 10 or the front of the shell 20, thereby achieving ventilation of the entire machine while avoiding affecting the overall shape of the electronic device, thereby improving the overall appearance refinement of the electronic device.

[0078] In some embodiments, Figure 8 As shown, the middle frame 10 includes an upper frame 14 , and the ventilation channel 12 is located on the upper frame 14 .

[0079] In the disclosed embodiment, the upper frame 14 can be made of metal, plastic, ceramic, glass and other materials, the air permeable channel 12 is located in the upper frame 14, the shell 20 can be a battery back cover, and after the battery back cover and the middle frame 10 are assembled, the air permeable channel 12 is designed inside the electronic device, and the air permeable function is realized through the assembly gap 13 between the battery back cover and the middle frame 10, and the top of the whole machine is free of holes, which greatly improves the exquisite appearance of the whole machine.

[0080] In some embodiments, the electronic device further includes: an audio device (not shown in the figure).

[0081] The audio device is installed in the installation cavity 11 , and the audio device is located on one side of the upper frame 14 .

[0082] It should be noted that when the internal air pressure of an electronic device changes, the internal air pressure becomes different from the air pressure outside the electronic device, causing an imbalance in the internal and external air pressure of audio devices (such as receivers and speakers), making it easy for the audio devices to cause noise problems due to the imbalance in internal and external air pressure.

[0083] Among them, the number of audio devices can be one or more, for example, two, etc., to respectively realize the functions of sound emission and sound reception, which is not limited in the embodiments of the present disclosure.

[0084] Exemplarily, the audio device can be used as a sound-generating device such as a speaker to convert an audio electrical signal into a sound signal audible to the human ear and transmit it to the outside of the electronic device. For example, the audio device can be applied to a speaker of an electronic device. The audio device is installed in the installation cavity 11, and the audio device is located on one side of the upper frame 14.

[0085] Of course, in some other embodiments, the audio device can also be used as a sound receiving device such as a microphone to convert the sound signals near the electronic device into audio electrical signals.

[0086] It is to be understood that in the present disclosure, "plurality" refers to two or more than two, and other quantifiers are similar. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. The singular forms "a", "the" and "the" are also intended to include plural forms, unless the context clearly indicates other meanings.

[0087] It is further understood that the terms "first", "second", etc. are used to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other, and do not indicate a specific order or degree of importance. In fact, the expressions "first", "second", etc. can be used interchangeably. For example, without departing from the scope of the present disclosure, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information.

[0088] It will be further understood that the terms “center”, “longitudinal”, “lateral”, “front”, “back”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0089] It can be further understood that, unless otherwise specified, “connection” includes a direct connection without other components between the two, and also includes an indirect connection with other components between the two.

[0090] It is further understood that, although the operations are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood as requiring the operations to be performed in the specific order shown or in a serial order, or requiring the execution of all the operations shown to obtain the desired results.
