Description

Housing assembly and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 21, 2023, with application number 202323534380.0 and application name “A housing assembly and electronic device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to a housing assembly and an electronic device. Background Art

[0003] With the continuous development and update of electronic device technology, terminal electronic devices such as mobile phones, tablets, and laptops have become increasingly common in people's lives. It is well known that mobile phones and other electronic devices cannot be exposed to water or get wet, otherwise it will damage the internal electronic structure of the phone. Therefore, to meet the needs of mobile phones and other terminal electronic devices for use in humid environments or rain, higher requirements are placed on the waterproof performance of electronic devices.

[0004] Taking a mobile phone as an example, an electronic device may include a housing and a display screen. The display screen is fixed to the housing, and the display screen and the housing together form a closed chamber. The camera module, speaker, microphone and other structures of the electronic device are all located in the chamber. The display screen, the housing and the joints between the two will adopt a waterproof sealing design to ensure the waterproofness of the electronic device. As the waterproof performance of electronic devices gets better and better, the airtightness of electronic devices is also getting better and better, that is, the airtightness of the chamber is enhanced. In scenarios such as pressing the touch screen or storing electronic devices, when the back cover or display screen of the electronic device is deformed due to external force, the air pressure inside the electronic device (inside the chamber) will change, making the air pressure inside the electronic device different from the air pressure outside, which will cause the internal and external air pressure of audio devices such as speakers in the chamber to be unbalanced, causing problems such as pressing noise during playback. Summary of the Invention

[0005] An embodiment of the present application provides a shell assembly and an electronic device. The shell assembly can achieve breathable performance while meeting the waterproof requirement, so as to balance the air pressure inside and outside the electronic device cavity, and avoid problems such as pressing noise caused by audio devices during playback due to unbalanced air pressure.

[0006] A first aspect of an embodiment of the present application provides a housing assembly comprising a housing member and a decorative member. The housing member has an inner surface for enclosing a chamber, and the housing member has a through hole. The decorative member is disposed within the through hole, with an outer surface of the decorative member opposing an inner wall of the through hole. The decorative member has a first vent extending to an outer surface of the decorative member. The first vent can communicate with a space located on the outer surface of the housing member, thereby communicating with an environment outside the chamber.

[0007] The housing assembly also includes a waterproof vent assembly, which is disposed on the decorative member and can communicate with the space located on the inner surface of the housing member. For example, the waterproof vent assembly can be located on the side of the decorative surface facing the chamber, allowing the waterproof vent assembly to communicate with the interior of the chamber and communicate with the first vent to form a first vent channel. Specifically, one end of the first vent channel communicates with the exterior of the chamber through the first vent, while the other end of the first vent channel communicates with the interior of the chamber through the waterproof vent, creating a gas passage between the interior and exterior of the electronic device chamber. This achieves ventilation while maintaining waterproof performance, thereby balancing the internal and external air pressures of the electronic device, enabling the electronic device to achieve both waterproof and breathable performance, and avoiding problems such as pressing noise caused by pressure imbalances. The structural design is simple, and compared to opening holes in lens covers, opening holes in decorative members is more feasible, has lower molding costs, and provides a higher yield rate.

[0008] Furthermore, compared to opening holes on the front of the lens cover, the first air holes are opened on the outer side of the decorative component facing the inner wall of the through hole. That is, the first air holes can be located on the circumferential side of the decorative component, making them less visible. Furthermore, the first air holes on the decorative component offer greater placement flexibility. For example, the first air holes can be located on a portion of the decorative component that does not protrude from the housing, making them invisible and significantly improving the aesthetics of the housing assembly and the electronic device.

[0009] The portion of the decorative part protruding from the shell part may overlap with part of the outer surface of the shell part in the thickness direction, or may not overlap. It is not limited to the scenario where the portion of the decorative part protruding from the shell part covers part of the shell part, and has higher structural design flexibility and wider applicability.

[0010] In one possible implementation, the height of the first air vent is lower than the height of the through hole, that is, the first air vent may not protrude from the shell part, so that the first air vent is hidden in the through hole and not exposed on the appearance surface of the shell component, so that the appearance of the first air vent opening is hidden and invisible, so that the shell component has a good ID appearance effect.

[0011] In one possible implementation, there is a first gap between the outer side surface of the decorative part and the inner wall surface of the through hole, so that the first air vent can be connected to the external environment of the chamber (the space on the outer surface side of the shell part) through the first gap, meeting the ventilation design requirements under the condition that the appearance of the first air vent is hidden.

[0012] In one possible implementation, the decorative part includes a protrusion and a fixing part that are connected to each other, the fixing part is fixed to the inner surface of the shell part, the circumferential outer side surface of the fixing part can be opposite to the inner wall surface of the through hole, and the circumferential outer side surface of the fixing part can form the outer side surface of the decorative part.

[0013] The protrusion protrudes from the outer surface of the housing, meaning that the height of the decorative element in the thickness direction is higher than the outer surface of the housing. This allows a portion of the camera module to protrude from the outer surface of the housing, increasing the space available for accommodating the camera module. This allows the thickness of the electronic device at the location of the camera module to be greater than that at other locations. While meeting the overall thickness requirements of the device, this increases the available space for the camera module, thereby enriching and improving the photographic performance of the electronic device.

[0014] The ventilation hole and the waterproof ventilation assembly are disposed adjacent to a side edge of the fixing portion. For example, the waterproof ventilation assembly and the first ventilation hole can be located adjacent to the outer peripheral edge of the decorative component. This reduces the impact of the waterproof ventilation assembly and the first ventilation hole on the light-guiding hole in the decorative component, thereby reducing or eliminating any impact on the layout design of the camera module. This provides a high level of integration and facilitates the integrated configuration of multiple camera modules.

[0015] In one possible implementation, the decorative component is a one-piece structural member. Specifically, the fixing portion, protruding portion, and extended portion are integrally formed to form a single decorative component. This reduces the number of structural components, simplifies the design, improves assembly efficiency, and helps reduce production costs and the difficulty of disassembly and maintenance. Furthermore, the decorative component itself does not require additional sealing and ventilation design, which helps reduce the cost of waterproof and breathable design.

[0016] In addition, the integrated decorative piece has good consistency and reliability, and good air permeability consistency, which is conducive to achieving better air permeability of the first air permeability channel to balance the air pressure effect.

[0017] In one possible implementation, the protrusion is smaller than the through-hole, allowing the protrusion to pass through the through-hole and project beyond the outer surface of the housing. During assembly, the protrusion of the decorative component is inserted through the through-hole from the inner surface of the housing, projecting beyond the housing. The securing portion is then secured to the inner surface of the housing to complete assembly of the decorative component and the housing. Compared to disassembling the decorative component into two separate structures and assembling them separately, the decorative component can be assembled directly from the inner surface of the housing, achieving single-sided assembly, simplifying assembly and improving assembly efficiency.

[0018] Among them, the size of the fixing part can be larger than the size of the through hole on the shell part, so that the fixing part cannot pass through the through hole from the inner surface side of the shell part. When the protrusion is protruded through the through hole from the inner surface side of the shell part during assembly, the fixing part can be clamped on the inner surface side of the shell part through the through hole, which is convenient for achieving fixation between the circumferential outer side surface of the fixing part and the inner surface of the shell part, which is beneficial to improving the assembly firmness of the decorative part and the shell part.

[0019] In one possible implementation, the housing assembly further includes a second ventilation channel. One end of the second ventilation channel communicates with the interior of the chamber through the waterproof and breathable assembly, while the other end communicates with the external environment of the chamber. This second ventilation channel also allows for air flow between the interior and exterior of the chamber, ensuring ventilation while maintaining waterproof performance, thereby balancing the internal and external air pressures of the electronic device. During use, if the first ventilation channel becomes clogged or damaged, the second ventilation channel can ensure ventilation of the electronic device, balancing the internal and external air pressures and avoiding issues such as pressing noise, significantly improving the reliability of the ventilation of the electronic device.

[0020] In one possible implementation, the shell assembly also includes a lens cover plate, which is located on an end of the protrusion facing away from the fixed portion. The protrusion is arranged around the lens cover plate, and a second gap is provided between the protrusion and the lens cover plate. The second gap can be connected to the space on the outer surface side of the shell member, so that the second gap is connected to the external environment of the chamber.

[0021] A third gap is defined between the lens cover and the fixed portion. The second and third gaps are sequentially connected to the waterproof vent assembly to form a second ventilation channel. One end of the second ventilation channel communicates with the exterior of the chamber through the second gap, while the other end communicates with the interior of the chamber through the waterproof vent assembly. This creates a gas flow between the interior and exterior of the chamber, meeting the waterproof and venting requirements of electronic devices.

[0022] In one possible implementation, the fixing portion includes a side wall and a top wall, with the side wall surrounding a surface of the top wall facing away from the protrusion. A mounting seat is provided on the surface of the top wall facing away from the protrusion, and an assembly slot is provided on the end of the mounting seat facing away from the side wall, into which the waterproof vent assembly is secured. The mounting seat can be adapted to the dimensions of the waterproof vent assembly, thereby reducing the space and volume of the structure for assembling the waterproof vent assembly while meeting assembly requirements, simplifying the structure of the decorative component and reducing its weight.

[0023] The assembly slot has a first conducting groove at its bottom and a first vent hole on its sidewall. The first vent hole is connected to the waterproof vent assembly in the assembly slot through the first conducting groove, thereby achieving electrical communication between the first vent hole and the waterproof vent assembly. That is, the waterproof vent assembly, the first conducting groove, the first vent hole, and the first gap are sequentially connected to form a first vent channel.

[0024] In one possible implementation, a second conductive groove is formed on the top wall, which is in electrical communication with the third gap and the first conductive groove. This allows electrical communication between the third gap and the waterproof breathable component. That is, the waterproof breathable component, the first conductive groove, the second conductive groove, the third gap, and the second gap are sequentially connected to form a second breathable channel.

[0025] In one possible implementation, the shell member includes a main body and an annular protrusion, one end of the protrusion is connected to the main body, the other end of the protrusion extends back to the main body, and the other end of the protrusion forms a through hole of the shell member.

[0026] In one possible implementation, the outer side surface of the raised portion is an arc-shaped surface, so that the shell part has a "crater" design at the through hole position, and the shell assembly has a good ID appearance, which is beneficial to improving the aesthetics of the shell assembly and the electronic device.

[0027] In one possible implementation, the waterproof breathable assembly includes a waterproof breathable membrane and a first adhesive layer, wherein the waterproof breathable membrane is fixed to the decorative component via the first adhesive layer. The first adhesive layer is provided with a second vent hole that communicates with the waterproof breathable membrane to meet the ventilation requirements of the waterproof breathable assembly.

[0028] In one possible implementation, the waterproof breathable assembly further includes a protective layer and a second adhesive layer. The protective layer is located on the side of the waterproof breathable membrane facing away from the first adhesive layer. The second adhesive layer is located between the protective layer and the waterproof breathable membrane. The protective layer is fixed to the waterproof breathable membrane by the second adhesive layer. The protective layer can strengthen and protect the waterproof breathable membrane, reducing or avoiding damage to the waterproof breathable membrane during the assembly of the waterproof breathable assembly.

[0029] The second adhesive layer is provided with a third air hole communicated with the waterproof breathable membrane, and the protective layer is provided with a fourth air hole communicated with the waterproof breathable membrane to meet the ventilation requirements of the waterproof breathable assembly.

[0030] A second aspect of an embodiment of the present application provides an electronic device, comprising a middle frame and any of the above-mentioned shell assemblies, wherein the shell member of the shell assembly is fixed to the middle frame, and the inner surface of the shell member and the middle frame are used to enclose a chamber.

[0031] In a possible implementation, a camera module is further included. The camera module is located in the cavity, and the camera module is opposite to the decorative part of the shell assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] In the embodiment of the present application, the electronic device is a mobile phone as an example. The mobile phone can be a bar phone, or the mobile phone can also be a folding phone. The following description is based on the example of the electronic device being a bar phone. In the embodiment of the present application, the electronic device is a mobile phone as an example.

[0067] FIG1 is a schematic structural diagram of an electronic device provided in an embodiment of the present application.

[0068] As shown in Figure 1, electronic device 100 includes a housing assembly 10 and a midframe 20. Midframe 20 can be disposed on one side of housing assembly 10. For example, housing assembly 10 can be a rectangular, plate-shaped structural member having opposing inner and outer surfaces. Midframe 20 can be a frame structural member and can be located on the inner surface side of housing assembly 10. The inner surfaces of midframe 20 and housing assembly 10 can together form a chamber that can be used to assemble and accommodate the various structural components of electronic device 100.

[0069] In the embodiment of the present application, for ease of description, as shown in FIG1 , the width direction of the housing assembly 10 is defined as the x-direction, the length direction of the housing assembly 10 is defined as the y-direction, and the thickness direction of the housing assembly 10 is defined as the z-direction. The inner surface and outer surface of the housing assembly 10 may be located on opposite sides of the thickness direction of the housing assembly 10. It will be understood that the length, width, and thickness in the embodiment of the present application are merely for ease of description and do not imply any limitation on the dimensions. For example, the length may be greater than, equal to, or less than the width.

[0070] Of course, in some other examples, the outer contour shape of the housing assembly 10 may also be a regular or irregular shape such as a square, a circle, an ellipse, a rounded rectangle, etc.

[0071] FIG2 is a schematic diagram of the disassembled structure of the electronic device in FIG1 .

[0072] As shown in Figure 2, the electronic device 100 also includes a display screen 30, and the display screen 30 and the shell assembly 10 are respectively fixed on opposite sides of the middle frame 20. For example, the display screen 30 and the shell assembly 10 are respectively located on opposite sides of the middle frame 20 along the thickness direction (z direction). The display screen 30 may also include an inner surface (not shown in the figure) and an outer surface 30a opposite to each other. The inner surface and the outer surface 30a of the display screen 30 may also be respectively located on opposite sides of the display screen 30 along the thickness direction. The inner surface of the display screen 30 is opposite to the inner surface of the shell assembly 10, and the outer surface 30a of the display screen 30 is opposite to the outer surface 10a of the shell assembly 10.

[0073] The display screen 30 is fixed to the middle frame 20 to enclose the above-mentioned cavity, that is, the inner surface of the shell assembly 10, the inner surface of the middle frame 20 and the inner surface of the display screen 30 together form a closed cavity to protect the structural parts located in the cavity and enhance the aesthetics of the electronic device 100.

[0074] The housing assembly 10 can serve as an exterior cover for the back of the electronic device 100 (see FIG1 ). For example, the outer surface 10a of the housing assembly 10 can form the exterior surface of the electronic device 100. The exterior surface design of the housing assembly 10 is conducive to improving the aesthetics of the electronic device 100.

[0075] The display screen 30 is used to display information and provide an interactive interface for the user. The outer surface 30a of the display screen 30 can serve as the display surface of the electronic device 100. For example, when a user is using the electronic device 100, the outer surface 30a of the display screen 30 can be placed toward the user, and the outer surface 10a of the housing assembly 10 can be placed away from the user.

[0076] The display screen 30 may be, but is not limited to, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MLED) display screen, or a quantum dot light-emitting diode (QLED) display screen, etc.

[0077] The electronic device 100 may further include a camera module 40 , which is used to implement functions such as photographing. The camera module 40 may be disposed in the aforementioned cavity.

[0078] For example, the camera module 40 can be a rear camera, such as the light inlet of the camera module 40 can face the outer surface 10a of the housing assembly 10. Alternatively, the camera module 40 can also be a front camera, such as the light inlet of the camera module 40 can face the display surface of the display screen 30.

[0079] The number of camera modules 40 of the electronic device 100 can be one. Alternatively, the number of camera modules 40 can also be multiple. In the embodiment of the present application, multiple camera modules 40 are used as an example for explanation. For example, the multiple camera modules 40 can be a periscope camera 40b, a main camera 40a, a first sub-camera 40c, and a second sub-camera 40d. The main camera 40a can be the camera module 40 that plays the main shooting role. The number of the first sub-camera 40c and the second sub-camera 40d can be one, or multiple. For example, the first sub-camera 40c and the second sub-camera 40d can be an ultra-wide-angle camera, a black and white camera, a depth camera, a macro camera, and the like. Providing multiple camera modules 40 allows the electronic device 100 to switch different cameras as needed when shooting or recording, or to combine images from multiple camera modules 40 to achieve better shooting effects.

[0080] The electronic device 100 may further include a flash 50 , which may be turned on in a low-brightness environment to illuminate the object to be photographed and assist the camera module 40 in completing photographing or recording.

[0081] In this embodiment, there is no specific limitation on the arrangement of the multiple camera modules 40 and the flash 50. For example, the flash 50 and the multiple camera modules 40 can be arranged sequentially along the length direction (y-direction) of the electronic device 100, so that the multiple camera modules 40 form a nearly rectangular area. Alternatively, the multiple camera modules 40 can be arranged sequentially along the circumference of the electronic device 100, so that the multiple camera modules 40 form a nearly circular area, which is beneficial for improving the space utilization of the electronic device 100. One or more camera modules 40 can also be arranged in the center of the circular area.

[0082] Among them, in order to meet the shooting requirements of the rear camera module 40, for example, the shell assembly 10 may include a shell part 11 and a lens cover plate 12. The shell part 11 can serve as the main load-bearing structural part of the shell assembly 10, the middle frame 20 can be fixed to the shell part 11, and the inner surface 11a of the shell part 11 is used to enclose a cavity of the electronic device 100.

[0083] It should be noted that the middle frame 20 and the shell member 11 can be formed separately, and the middle frame 20 and the shell member 11 can be fixed together by welding, clamping, bonding, etc. Alternatively, the middle frame 20 and the shell member 11 can also be formed as one piece.

[0084] The housing 11 may be formed of metal, ceramic, glass, etc., which helps meet the requirements of gloss, fashion and aesthetics of the electronic device 100. The middle frame 20 may also be formed of metal, ceramic, glass, etc.

[0085] The lens cover 12 can be fixed to the housing 11, and the position of the lens cover 12 can be opposite to the camera module 40 and the flash 50 located in the chamber. The lens cover 12 can allow light to pass through the housing assembly 10, that is, it can allow light outside the electronic device 100 to pass through the lens cover 12 into the interior of the chamber of the electronic device 100 and be transmitted to the camera module 40. Alternatively, it can allow light emitted by the camera module 40 or the flash 50 to pass through the lens cover 12 and be irradiated to the outside of the chamber of the electronic device 100.

[0086] The lens cover 12 can be a light-transmitting structural member such as transparent glass or plastic. The shape of the lens cover 12 is not specifically limited in this embodiment. The shape of the lens cover 12 can correspond to the shape of the distribution arrangement of multiple camera modules 40 and flash lights 50. For example, the shape of the lens cover 12 can be rectangular, circular, diamond-shaped or other regular or irregular shapes.

[0087] The inner surface of the lens cover 12 (the side facing the electronic device chamber) may have a light-shielding layer (not shown), which may be provided with light-transmitting through holes. The number and location of the light-transmitting through holes may correspond to the camera module 40 and the flash 50. Light from outside the electronic device chamber may pass through the lens cover 12 and the light-transmitting through holes and then be directed to the camera module 40, thereby achieving an imaging function. Light from the flash 50 may pass through the light-transmitting through holes and the lens cover 12 to be directed to the outside of the electronic device chamber.

[0088] The shell assembly 10 may also include a decorative part 13, which is also fixed on the shell assembly 11. The decorative part 13 can be arranged around the lens cover 12. The decorative part 13 can serve to decorate the lens cover 12 and the camera module 40 to enhance the aesthetics of the shell assembly 10 and the entire electronic device 100.

[0089] The electronic device 100 may further include a circuit board, a battery, a charging management module, a power management module, etc. (not shown in the figure), and the circuit board, the battery, the charging management module, the power management module, etc. may be fixed inside the above-mentioned cavity.

[0090] The circuit board may include a processor, and the processor may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, a display processing unit (DPU), and / or a neural-network processing unit (NPU). Among them, the controller may be the nerve center and command center of the electronic device 100. The controller may generate an operation control signal based on the instruction opcode and the timing signal to complete the control of instruction fetching and execution. A memory may also be provided in the processor for storing instructions and data.

[0091] The processor may include one or more interfaces, which can be used to connect a charger to charge the electronic device 100. The interface can also be used to implement data transmission between the electronic device 100 and an external device, for example, it can also be used to connect headphones, projection devices, etc.

[0092] The charging management module is configured to receive charging input from a charger. The charger can be either a wireless charger or a wired charger. In some wired charging examples, the charging management module can receive charging input from the wired charger via an interface. In some wireless charging embodiments, the charging management module can receive wireless charging input via a wireless charging coil on the electronic device 100. The charging management module can charge the battery and also provide power to the electronic device 100 through the power management module.

[0093] The power management module connects the battery, charging management module, and processor. It receives input from the battery and / or charging management module and provides power to the processor, memory, display 30, camera module 40, and other components. The power management module can also monitor parameters such as battery capacity, battery cycle count, and battery health (leakage, impedance), among others.

[0094] In some examples, the power management module can be provided in a processor of a circuit board. In other examples, the power management module and the charging management module can also be provided in the same device.

[0095] The structures illustrated in the embodiments of this application do not constitute specific limitations on the electronic device 100. In other embodiments of this application, the electronic device 100 may include more or fewer components than shown, or may combine or separate certain components, or may have different component arrangements. For example, the electronic device 100 may also include devices such as a communication module, a sensor, a microphone, and a speaker.

[0096] With the rapid development and widespread application of electronic device technology, the waterproof and airtight performance of electronic devices is getting better and better. For example, IPX8 waterproofing has gradually become a standard feature of flagship mobile phones on the market. Due to the good airtightness of electronic devices, when the display and / or housing components of the electronic device are deformed by external forces in scenarios such as pressing the touch screen or storing the electronic device, the air pressure inside the electronic device's cavity will change, resulting in an imbalance in the air pressure inside and outside the electronic device. This in turn can cause an imbalance in the internal and external air pressure of audio components such as speakers, causing problems such as pressing noise during audio playback.

[0097] To ensure electronic equipment is waterproof and breathable, a ventilation channel can be installed inside the electronic device, with a waterproof and breathable layer on top. This allows the environment inside and outside the electronic device to flow through the ventilation channel and the waterproof and breathable layer, achieving balanced air pressure inside and outside the electronic device while ensuring waterproof performance. Furthermore, the waterproof and breathable layer and ventilation channel can also be used for waterproof and airtightness testing during device production.

[0098] In order to ensure the balance of internal and external air pressure of the electronic device, two air permeation channels can be formed on the housing assembly to avoid problems such as blockage of one air permeation channel during use, which may lead to air pressure imbalance.

[0099] For example, the decorative part may include a structural part and an appearance part. The structural part and the appearance part are two independently formed structures. The structural part and the appearance part can be assembled together to form a decorative part. The structural part can be fixed on the inner surface of the shell part. The appearance part is fixed to the shell part through the structural part. The appearance part can be protruded on the outer surface of the shell part. The appearance part is arranged around the lens cover.

[0100] A first gap may be provided between the lens cover plate and the exterior member, the first gap being in communication with the environment outside the chamber; a second gap may be provided between the lens cover plate and the structural member; a waterproof breathable layer may be located on the structural member and in communication with the interior of the chamber; the waterproof breathable layer, the second gap, and the first gap are sequentially connected to form a first breathable passage; and the lens cover plate may have a through-hole provided therethrough; the waterproof breathable layer, the second gap, and the breathable hole are sequentially connected to form a second breathable passage.

[0101] However, the opening on the front side of the lens cover (the side facing away from the chamber) affects the industrial design (ID) appearance of the housing assembly, affecting the aesthetics of the housing assembly and the electronic device. Furthermore, the opening requires separate protection such as dust screens, which is costly. Furthermore, the decorative piece is assembled from two independent structures, resulting in a complex structure, high production and design costs, and difficult disassembly and maintenance. Furthermore, a waterproof seal design is required between the two independent structures, complicating the waterproof seal design.

[0102] In some other examples, the exterior component can cover a portion of the outer surface of the housing, creating a third gap between the exterior component and the outer surface of the housing. The waterproof breathable layer, the second gap, and the third gap are sequentially connected to form a second ventilation channel. This approach is only applicable to designs where the exterior component covers a portion of the outer surface of the housing, limiting its scope of application. Furthermore, the assembly of two separate structures still presents challenges such as complex structure, complicated waterproof sealing design, and difficulty in disassembly and maintenance.

[0103] Based on this, an embodiment of the present application provides a housing assembly in which a decorative member is assembled over a through-hole of a housing member, so that a waterproof and breathable assembly on the decorative member can communicate with the interior of a cavity defined by the inner surface of the housing member. A first vent hole is formed on the decorative member, enabling the first vent hole to communicate with the exterior of the cavity defined by the inner surface of the housing member. The waterproof and breathable assembly communicates with the first vent hole to form a first ventilation channel. Specifically, one end of the first ventilation channel communicates with the external environment of the cavity through the first vent hole, while the other end of the first ventilation channel communicates with the interior of the cavity through the waterproof and breathable assembly, thereby establishing a gas passage between the interior and exterior of the electronic device cavity. This achieves ventilation while ensuring waterproof performance, thereby balancing the internal and external air pressures of the electronic device, enabling the electronic device to achieve both waterproof and breathable performance, and avoiding problems such as pressing noise caused by imbalanced internal and external air pressures. The present invention has a simple structural design, low molding costs, high product yield, and better feasibility and wide applicability. The first ventilation hole is located on the circumferential side of the decorative component, which makes the housing assembly have a better ID appearance and significantly improves the aesthetics of the housing assembly and the electronic device.

[0104] FIG3 is an enlarged view of a partial structure of a shell assembly provided in an embodiment of the present application.

[0105] 3 , the housing assembly 10 includes a housing member 11, a decorative member 13, and a lens cover plate 12. It should be noted that FIG3 only shows a portion of the structure where the housing member 11, the decorative member 13, and the lens cover plate 12 are assembled.

[0106] The housing member 11 may also have an inner surface 11a and an outer surface 11b that are opposite to each other. The outer surface 11b and the inner surface 11a of the housing member 11 are used to form part of the inner surface and part of the outer surface of the housing assembly 10, respectively. That is, the inner surface 11a of the housing member 11, the inner surface of the middle frame 20, and the inner surface of the display screen 30 form a cavity of the electronic device 100. The outer surface 11b of the housing member 11 is arranged away from the cavity and is used to form part of the appearance of the electronic device 100. The inner surface 11a and the outer surface 11b of the housing member 11 may be located on opposite sides of the housing member 11 in the thickness direction.

[0107] The decorative part 13 is fixedly assembled on the shell part 11, and part of the decorative part 13 can be set to protrude from the outer surface 11b of the shell part 11 (as shown in Figure 5), that is, the height of the decorative part 13 in the thickness direction (z direction) can be higher than the height of the outer surface 11b of the shell part 11 in the thickness direction (z direction).

[0108] The lens cover 12 is fixedly mounted on the decorative member 13. For example, the lens cover 12 can be located on the end of the decorative member 13 that protrudes from the housing 11. The decorative member 13 surrounds the lens cover 12, allowing the lens cover 12 to protrude from the outer surface 11b of the housing 11. Portions of the camera module can also protrude from the outer surface 11b of the housing 11, increasing the space available for accommodating the camera module. This allows the thickness of the electronic device at the location of the camera module (lens cover 12) to be greater than that of the electronic device at other locations. This increases the available space for the camera module while meeting the overall thickness requirements, thereby enriching and improving the electronic device's imaging performance.

[0109] Among them, the structural shape of the decorative part 13 can be consistent with the structural shape of the lens cover 12. For example, in an embodiment of the present application, the lens cover 12 can be a circular transparent lens, and the decorative part 13 can also be a structural part with a circular outer contour. Both the lens cover 12 and the decorative part 13 can have outer side surfaces distributed along the circumferential direction.

[0110] Exemplarily, the decorative piece 13 can be arranged to protrude from the lens cover plate 12 (as shown in Figure 5), that is, the height of the decorative piece 13 in the z direction can be higher than the height of the lens cover plate 12 in the z direction. The protruding decorative piece 13 can protect the lens cover plate 12 to reduce or avoid damage to the lens cover plate 12 during use, thereby ensuring shooting performance.

[0111] FIG4 is a schematic diagram of the disassembled structure of the shell assembly in FIG3 .

[0112] As shown in FIG. 4 , a through hole 111 may be provided on the housing 11 . The through hole 111 is used to assemble the decorative element 13 . The decorative element 13 may be disposed in the through hole 111 and fixedly assembled with the housing 11 .

[0113] A first ventilation hole 131 is formed on the decorative member 13 , and the first ventilation hole 131 is used to form a first ventilation channel to balance the air pressure inside the electronic equipment room and the external environment.

[0114] The housing assembly 10 further includes a waterproof breathable assembly 14 , which is disposed on the decorative member 13 . The waterproof breathable assembly 14 is capable of allowing gas to pass through and blocking liquid from passing through, and has both breathable and waterproof properties.

[0115] It should be noted that a light-guiding through hole (not shown in the figure) may also be provided on the decorative part 13, and the light-guiding through hole may be arranged corresponding to the light-transmitting through hole on the lens cover 12 and the camera module in the cavity. For example, the light-guiding through hole may be used to accommodate the camera module, or the light-guiding through hole may allow light to pass through to illuminate the camera module.

[0116] The shape of the light-guiding hole can match the shape of the lens of the camera module corresponding to the light-guiding hole. For example, if the lens of the camera module is circular, the light-guiding hole can also be circular. Exemplarily, the shape of the light-guiding hole can be regular or irregular shapes such as circular, elliptical, racetrack circular, square, etc.

[0117] FIG5 is a schematic front view of a cross section of the housing assembly along the AA plane in FIG3 .

[0118] As shown in Figure 5, the waterproof breathable component 14 and the first breathable hole 131 can be arranged adjacent to one side edge of the decorative component 13. For example, the waterproof breathable component 14 and the first breathable hole 131 can be located adjacent to the outer peripheral edge of the decorative component 13, thereby reducing the impact of the opening of the waterproof breathable component 14 and the first breathable hole 131 on the light-guiding through-hole on the decorative component 13, thereby reducing or avoiding the impact on the layout design of the camera module, and having a high degree of integration, which is conducive to the integrated setting of multiple camera modules.

[0119] FIG6 is an enlarged schematic diagram of the structure of portion B in FIG5 .

[0120] As shown in Figure 6, the decorative part 13 can be partially located in the through hole 111, with the side of the decorative part 13 opposite to the inner wall surface of the through hole 111 as the outer side surface 13a of the decorative part 13, that is, the inner wall surface of the through hole 111 surrounds the outer side surface 13a of the decorative part 13, and the outer side surface 13a of the decorative part 13 can be distributed along the circumference of the decorative part 13.

[0121] The first air vent 131 of the decorative part 13 extends to the outer side surface 13a of the decorative part 13 (as shown in Figure 4), that is, the first air vent 131 is located on the circumferential side of the decorative part 13. Continuing to refer to Figure 6, the first air vent 131 can be connected to the space located on the outer surface 11b side of the shell part 11, that is, the first air vent 131 is connected to the environment outside the electronic device cavity.

[0122] The waterproof breathable component 14 can communicate with the space located on the inner surface 11a of the housing 11. For example, the waterproof breathable component 14 can be located on the side of the decorative component 13 facing the chamber. For example, the waterproof breathable component 14 can communicate with the interior of the electronic device chamber. The waterproof breathable component 14 can communicate with the first breathable hole 131 to form a first breathable channel, such as the first breathable channel S1 shown in the figure. Specifically, one end of the first breathable channel S1 communicates with the environment outside the chamber through the first breathable hole 131, and the other end of the first breathable channel S1 communicates with the interior of the chamber through the waterproof breathable component 14. This establishes a gas passage between the interior and exterior of the electronic device chamber, achieving a breathable effect while ensuring waterproof performance. This balances the air pressure inside and outside the electronic device, enabling the electronic device to achieve both waterproof and breathable performance, and avoiding problems such as pressing noise caused by imbalanced internal and external air pressure. The first ventilation hole 131 is opened on the decorative part 13 to form the first ventilation channel S1. The structural design is simple, and compared with opening holes on the lens cover plate 12, etc., it has better feasibility, lower molding cost, and higher finished product yield.

[0123] Furthermore, compared to opening holes on the front surface of the lens cover 12, the first air holes 131 are provided on the outer side surface 13a of the decorative member 13 facing the inner wall of the through hole 111. Specifically, the first air holes 131 can be located on the circumferential side of the decorative member 13, making them less visible. Furthermore, the first air holes 131 on the decorative member 13 offer greater flexibility in placement. For example, the first air holes 131 can be located on a portion of the decorative member 13 that does not protrude from the housing 11, making them invisible and significantly improving the aesthetics of the housing assembly and the electronic device.

[0124] The portion of the decorative part 13 protruding from the shell part 11 may overlap with part of the outer surface 11b of the shell part 11 in the thickness direction, or may not overlap. It is not limited to the scenario where the portion of the decorative part 13 protruding from the shell part 11 covers part of the shell part 11, and has higher structural design flexibility and wider applicability.

[0125] It should be noted that the first air hole 131 and the waterproof breathable component 14 are respectively located on the decorative part 13, and the first air hole 131 and the waterproof breathable component 14 can be connected by grooves inside the decorative part 13. For example, the decorative part 13 has a first conductive groove 1335 inside, and the two ends of the first conductive groove 1335 are respectively connected to the first air hole 131 and the waterproof breathable component 14.

[0126] The first air vent 131 is in communication with the external environment of the chamber. For example, the first air vent 131 may protrude from the outer surface 11b of the shell 11. For example, the first air vent 131 may extend to the portion of the decorative part 13 that protrudes from the shell 11, so that the first air vent 131 is exposed outside the shell 11 and the decorative part 13, thereby achieving communication between the first air vent 131 and the space on the outer surface side of the shell 11, thereby achieving communication between the first air vent 131 and the external environment of the chamber.

[0127] Alternatively, to further enhance the aesthetics of the housing assembly, for example, the first ventilation hole 131 may not protrude from the outer surface 11b of the housing member 11. For example, the height of the first ventilation hole 131 in the thickness direction (z-direction) may be lower than the height of the through-hole 111 in the thickness direction (z-direction), and the first ventilation hole 131 may extend to the portion of the decorative member 13 that does not protrude from the housing member 11. This allows the first ventilation hole 131 to be concealed within the through-hole 111 and not exposed on the exterior surface of the housing assembly 10, thus making the first ventilation channel opening invisible and giving the housing assembly 10 a superior ID appearance.

[0128] In the scenario where the first vent 131 is hidden, to achieve communication between the first vent 131 and the outside of the chamber, for example, as further shown in FIG6 , a first gap 132 may be defined between the outer side 13a of the decorative member 13 and the inner wall of the through hole 111. The first gap 132 is in communication with the space located on the outer surface 11b of the housing 11. The first vent 131 extending to the outer side 13a of the decorative member 13 is in communication with the first gap 132, thereby allowing the first vent 131 to communicate with the outside of the chamber (the space on the outer surface of the housing 11) through the first gap 132. In other words, the waterproof vent assembly 14, the first conducting groove 1335, the first vent 131, and the first gap 132 are sequentially connected to form a first vent channel S1. One end of the first vent channel S1 communicates with the outside of the chamber through the first gap 132, while the other end communicates with the interior of the chamber through the waterproof vent assembly 14.

[0129] FIG. 7 is a schematic structural diagram of a decorative component in the housing assembly of FIG. 3 .

[0130] As shown in FIG7 , the decorative member 13 may include a protruding portion 134 and a fixing portion 133 connected to each other, with the fixing portion 133 being fixed to the inner surface of the housing. For example, if the outer contour of the decorative member 13 is a circular structure, the outer contours of the protruding portion 134 and the fixing portion 133 may also be circular. The fixing portion 133 may be located within the through hole 111 of the housing 11 (see FIG6 ), and the circumferential outer side surface of the fixing portion 133 may be opposite the inner wall surface of the through hole 111, thereby forming the outer side surface 13a of the decorative member 13.

[0131] For example, the circumferential outer side surface of the fixing portion 133 can be fixed to the inner surface of the housing member by bonding. The end of the fixing portion 133 facing away from the protruding portion 134 can also have an extension portion 135, that is, the fixing portion 133 is located between the protruding portion 134 and the extension portion 135. The extension portion 135 can be an annular structure. The extension portion 135 and the fixing portion 133 can be bonded to the inner surface 11a of the housing member 11 together, thereby improving the secure assembly and fixation of the decorative member 13 to the housing member 11.

[0132] Alternatively, in some other examples, the fixing portion 133 may also be fixedly assembled with the housing member by means of clamping, welding, threaded fastening, or the like.

[0133] The protrusion 134 is arranged to protrude from the outer surface 11b of the shell 11 (refer to Figure 6). For example, the protrusion 134 can also be an annular structural member, and the lens cover 12 can be arranged on one end of the protrusion 134 facing away from the fixing portion 133, and the protrusion 134 is arranged around the outside of the lens cover 12.

[0134] The waterproof breathable component 14 and the first breathable hole 131 can be respectively arranged on the fixing portion 133 (refer to Figure 6). For example, the waterproof breathable component 14 is located on the side of the fixing portion 133 facing away from the protruding portion 134. The first breathable hole 131 and the waterproof breathable component 14 can be located on the fixing portion 133 at a position adjacent to the edge of one side of the fixing portion 133. The first breathable hole 131 can extend to the circumferential outer surface of the fixing portion 133.

[0135] Continuing with FIG. 7 , the decorative member 13 can be a one-piece structural member, i.e., the fixing portion 133, the protruding portion 134, and the extending portion 135 are integrally formed to form the one-piece decorative member 13. For example, the one-piece decorative member 13 comprising the protruding portion 134, the fixing portion 133, and the extending portion 135 can be formed through mold preparation, computerized numerical control (CNC) machining, or other processing. This reduces the number of structural components, simplifies the structural design, improves assembly efficiency, and also helps reduce production costs and the difficulty of disassembly and maintenance. The decorative member 13 itself does not require additional sealing and ventilation design, which helps reduce the cost of waterproof and breathable design.

[0136] In addition, the integrated decorative component 13 has good consistency and reliability, and good air permeability consistency, which is conducive to achieving better air permeability of the first air permeability channel to balance the air pressure effect.

[0137] FIG8 is a schematic structural diagram of a cross section of the housing assembly in FIG3 formed along the AA plane from another perspective.

[0138] As shown in Figure 8, the size of the protrusion 134 of the decorative part 13 can be smaller than the size of the through hole 111 on the shell part 11. For example, taking the outer contours of the protrusion 134 and the fixing part 133 as a circle, the centers of the protrusion 134, the through hole 111 and the fixing part 133 can be projected to coincide with each other in the thickness direction, and the radial dimension (or maximum radial dimension) of the protrusion 134 can be smaller than the radial dimension of the through hole 111, so that the protrusion 134 can pass through the through hole 111 and protrude from the outer surface 11b of the shell part 11.

[0139] During assembly, from the inner surface 11a side of the shell part 11, the protrusion 134 of the decorative part 13 is passed through the through hole 111 and protruded from the shell part 11, so that the fixing part 133 is fixed to the inner surface 11a of the shell part 11 to complete the assembly of the decorative part 13 and the shell part 11. Compared with disassembling the decorative part 13 into two independent structures, the decorative part 13 can be directly assembled to the shell part 11 from the inner surface 11a side of the shell part 11, realizing single-sided assembly, and the assembly method is simple, which is conducive to improving assembly efficiency.

[0140] For example, the size of the fixing portion 133 can be larger than the size of the through-hole 111 on the housing member 11. For example, the radial dimension (or maximum radial dimension) of the fixing portion 133 can be larger than the radial dimension of the through-hole 111. This prevents the fixing portion 133 from passing through the through-hole 111 from the inner surface 11a of the housing member 11. When the protrusion 134 is protruded through the through-hole 111 from the inner surface 11a of the housing member 11 during assembly, the fixing portion 133 can be secured to the inner surface 11a of the housing member 11 through the through-hole 111. This facilitates the fixation between the circumferential outer side surface of the fixing portion 133 and the inner surface 11a of the housing member 11, thereby improving the assembly security of the decorative component 13 and the housing member 11.

[0141] Of course, in some other examples, the size of the fixing portion 133 may also be smaller than or equal to the size of the through hole 111 on the housing 11 .

[0142] To ensure balanced air pressure inside and outside the electronic device's chamber, the housing assembly may also include a second ventilation channel. A waterproof vent assembly is also located on the second ventilation channel. One end of the second ventilation component can communicate with the interior of the chamber through the waterproof vent assembly, while the other end of the second ventilation channel can communicate with the external environment of the chamber. This second ventilation channel also allows for a gas flow between the chamber's interior and exterior, ensuring breathability while maintaining waterproof performance, thereby balancing the air pressure inside and outside the electronic device. During use, if the first ventilation channel becomes clogged or damaged, the second ventilation channel can ensure ventilation of the electronic device, balancing the internal and external air pressures and avoiding issues such as pressing noise, significantly improving the reliability of the electronic device's ventilation.

[0143] FIG9 is a partial enlarged view of the structure of portion C in FIG8 .

[0144] For example, as shown in FIG. 9 , the lens cover 12 may be located on an end of the protruding portion 134 of the decorative element 13 that faces away from the fixing portion 133 .

[0145] The protrusion 134 is arranged around the lens cover 12, and the circumferential inner side surface of the protrusion 134 (the side facing the hollow structure inside the annular protrusion 134) is opposite to the circumferential outer side surface of the lens cover 12, so that there is a second gap 15 between the inner side surface of the protrusion 134 and the outer side surface of the lens cover 12. The second gap 15 can be connected to the space on the side of the outer surface 11b of the shell 11, that is, the second gap 15 is connected to the external environment of the electronic device cavity.

[0146] A third gap 16 is defined between the lens cover 12 and the fixing portion 133. The second gap 15, the third gap 16, and the waterproof breathable assembly 14 are sequentially connected to form a second breathable passage, as shown by the dotted line in the figure, called second breathable passage S2. Specifically, one end of the second breathable passage S2 communicates with the external environment of the chamber through the second gap 15, while the other end communicates with the interior of the chamber through the waterproof breathable assembly 14. This creates a gas flow between the interior and exterior of the chamber, meeting the waterproof and breathable requirements of electronic equipment.

[0147] The connection between the waterproof breathable component 14 on the fixing portion 133 and the third gap 16 can also be achieved by forming grooves in the decorative member 13. For example, the decorative member 13 can further include a second conductive groove 1336. One end of the second conductive groove 1336 can extend to the surface of the fixing portion 133 facing the lens cover 12, and the other end of the second conductive groove 1336 can be connected to the waterproof breathable component 14. For example, the other end of the second conductive groove 1336 can be connected to the waterproof breathable component 14 through the first conductive groove 1335. In other words, the waterproof breathable component 14, the first conductive groove 1335, the second conductive groove 1336, the third gap 16, and the second gap 15 are sequentially connected to form the second breathable channel S2.

[0148] FIG10 is a schematic cross-sectional view of the decorative element in FIG7 .

[0149] 10 , the fixing portion 133 of the decorative member 13 may include a top wall 1331 and a side wall 1332, wherein the side wall 1332 may be disposed around a surface of the top wall 1331 facing away from the protrusion 134. The side wall 1332 may also be an annular structure, and the protrusion 134 and the side wall 1332 may be located on two opposite sides of the top wall 1331, respectively.

[0150] FIG. 11 is a schematic structural diagram of the decorative element in FIG. 7 from another perspective.

[0151] As shown in FIG. 11 , a raised mounting seat 1333 may be provided on a surface of the top wall 1331 facing away from the protruding portion 134 , and the mounting seat 1333 is used to assemble the waterproof and breathable component.

[0152] Mounting seat 1333 can be positioned adjacent to the outer edge of side wall 1332 and connected to extension 135 to enhance the strength and reliability of mounting seat 1333 and the entire decorative element 13. Mounting seat 1333, protruding from top wall 1331, allows for assembly of the waterproof and breathable assembly. Mounting seat 1333 can be adapted to the dimensions of the waterproof and breathable assembly, thereby reducing the space and volume of the structure used to assemble the waterproof and breathable assembly while meeting assembly requirements. This helps simplify the structure of decorative element 13 and reduce its weight.

[0153] Illustratively, an assembly groove 1334 may be provided on one end of the mounting seat 1333 facing away from the side wall 1332 , and the waterproof breathable component may be fixed in the assembly groove 1334 .

[0154] A first vent hole 131 may be provided on the side wall 1332 , and the first vent hole 131 extends to the circumferential outer surface of the side wall 1332 . To achieve conduction between the first vent hole 131 and the waterproof breathable component, a first conducting groove 1335 may be provided at the bottom of the assembly groove 1334 .

[0155] FIG12 is a partial enlarged view of the structure of portion D in FIG10 .

[0156] As shown in Figure 12, one end of the first conducting groove 1335 is connected to the first air hole 131, and the other end of the first conducting groove 1335 is connected to the assembly groove 1334 that accommodates the waterproof and breathable component 14, so that the first air hole 131 can be connected to the waterproof and breathable component 14 in the assembly groove 1334 through the first conducting groove 1335.

[0157] A second conducting groove 1336 is further defined on the top wall 1331 , and one end of the second conducting groove 1336 can be in electrical communication with the first conducting groove 1335 .

[0158] FIG13 is a structural schematic diagram of the cross section of the housing assembly in FIG3 formed along the AA plane from another perspective.

[0159] As shown in FIG13 , the other end of the second conducting groove 1336 can extend to the surface of the top wall 1331 facing the lens cover plate 12, allowing the other end of the second conducting groove 1336 to communicate with the third gap 16 between the lens cover plate 12 and the decorative member 13. This allows the third gap 16 to communicate with the assembly groove 1334 and the waterproof breathable assembly 14 within the assembly groove 1334 via the second conducting groove 1336 and the first conducting groove 1335. The waterproof breathable assembly 14, the first conducting groove 1335, the first vent 131, and the first gap 132 are sequentially connected to form a first breathable channel S1. The waterproof breathable assembly 14, the first conducting groove 1335, the second conducting groove 1336, the third gap 16, and the second gap 15 are sequentially connected to form a second breathable channel S2.

[0160] In some examples, the shell member 11 can be a flat plate-shaped structural member. For example, the shell member 11 can be a rectangular flat plate-shaped structural member. It should be noted that the peripheral edge of the shell member 11 can be a plane, or the peripheral edge of the shell member 11 can be at least partially an arc-shaped surface with a certain curvature.

[0161] Alternatively, in some examples, as shown in Figure 13, the shell member 11 may include a main body 112 and an annular protrusion 113, the annular protrusion 113 is hollow inside, one end of the protrusion 113 is connected to the main body 112, and the other end extends back to the main body 112, and the other end of the protrusion 113 can form a through hole 111 of the shell member 11.

[0162] The main body 112 and the raised portion 113 can be integrally formed, making the housing 11 a one-piece structural member. Alternatively, in some examples, the main body 112 and the raised portion 113 can be formed separately, and the raised portion 113 and the main body 112 can be assembled together to form the housing 11 by bonding, welding, or clamping.

[0163] The shape of the raised portion 113 may be a circular ring, or the shape of the raised portion 113 may be a regular or irregular shape such as a square, a rounded square, or an ellipse.

[0164] The outer side surface 113a of the raised portion 113 is the side of the raised portion 113 that faces away from the internal hollow structure.
