Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a housing assembly and an electronic equipment. Background Art

[0002] With the continuous development and update of electronic equipment technology, terminal electronic equipment such as mobile phones, tablets, notebooks, etc. have become more and more common in people's lives. It is well known that mobile phones and other electronic equipment cannot be soaked in water or exposed to water, otherwise the internal electronic structure of the mobile phone will be damaged. Therefore, in order to meet the use of mobile phones and other terminal electronic equipment in humid environments or rainy scenes, higher requirements are placed on the waterproof performance of electronic equipment.

[0003] 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 becomes better and better, the air tightness of electronic devices is also getting better and better, that is, the air tightness of the chamber is enhanced. In scenes such as pressing the touch screen and 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 pressures of audio devices such as speakers in the chamber to be unbalanced, and cause problems such as pressing noise during playback. Utility Model Content

[0004] The embodiments of the present application provide a shell assembly and an electronic device. The shell assembly can achieve breathability while meeting the waterproof requirement to balance the air pressure inside and outside the chamber of the electronic device, thereby avoiding problems such as pressing noise caused by audio components during playback due to unbalanced air pressure.

[0005] A first aspect of an embodiment of the present application provides a housing assembly, comprising a housing member and a decorative member, wherein the inner surface of the housing member is used to enclose a chamber, and the housing member has a through hole. The decorative member is disposed in the through hole, and the outer side surface of the decorative member is opposite to the inner wall surface of the through hole, and the decorative member has a first vent hole, which extends to the outer side surface of the decorative member, and the first vent hole can be connected to a space located on the outer surface side of the housing member, so that the first vent hole is connected to the environment outside the chamber.

[0006] The housing component also includes a waterproof and breathable component, which is arranged on the decorative part. The waterproof and breathable component can be connected to the space on the inner surface side of the housing part, such as the waterproof and breathable component can be located on the side of the decorative surface facing the chamber, so that the waterproof and breathable component is connected to the inside of the chamber, and the waterproof and breathable component is connected to the first breathable hole to form a first breathable channel. That is, one end of the first breathable channel is connected to the outside of the chamber through the first breathable hole, and the other end of the first breathable channel is connected to the inside of the chamber through the waterproof and breathable component, so as to realize the gas passage between the inside and outside of the electronic device chamber, and realize the breathable effect under the condition of ensuring the waterproof performance, so as to balance the air pressure inside and outside the electronic device, so that the electronic device can have both waterproof and breathable performance, and avoid the problems such as pressing noise caused by the imbalance of internal and external air pressure of the electronic device. The structural design is simple. Compared with opening holes on the lens cover plate, etc., opening holes on the decorative part has better feasibility, and the molding cost is low, and the finished product yield is high.

[0007] In addition, compared with opening a hole on the front of the lens cover, the first air hole is opened on the outer side of the decorative member facing the inner wall of the through hole, that is, the first air hole can be located on the circumferential side of the decorative member, so that the first air hole is not easily observed from the appearance. And the first air hole on the decorative member has higher setting flexibility, such as the first air hole can be located on the part of the decorative member that does not protrude from the housing member, so that the first air hole is hidden and invisible from the appearance, which significantly improves the aesthetics of the housing assembly and the electronic device.

[0008] The portion of the decorative part protruding from the shell part may overlap with the outer surface of part 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.

[0009] In one possible implementation, the height of the first air hole is lower than the height of the through hole, that is, the first air hole may not protrude from the shell part, so that the first air hole 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 channel opening is hidden and invisible, so that the shell component has a good ID appearance effect.

[0010] In one possible implementation, there is a first gap between the outer side surface of the decorative component 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 component) through the first gap, meeting the ventilation design requirements under the condition that the appearance of the first air vent is hidden.

[0011] In one possible implementation, the decorative part includes a protrusion and a fixing part 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.

[0012] The protrusion is arranged to protrude from the outer surface of the shell, that is, the height of the decorative part in the thickness direction is higher than the height of the outer surface of the shell in the thickness direction. This allows part of the camera module to protrude from the outer surface of the shell, increasing the space for accommodating the camera module, so that the thickness of the electronic device at the camera module position can be greater than the thickness of the electronic device at other positions. Under the condition of meeting the thickness requirements of the entire device, the available space of the camera module is increased, which is conducive to enriching and improving the shooting performance of the electronic device.

[0013] The ventilation hole and the waterproof ventilation component are arranged on one side edge of the fixing part. For example, the waterproof ventilation component and the first ventilation hole can be located on the decorative part near the outer peripheral edge, reducing the influence of the waterproof ventilation component and the first ventilation hole on the light-guiding hole on the decorative part, thereby reducing or avoiding the influence on the layout design of the camera module, with high integration, which is conducive to realizing the integrated setting of multiple camera modules.

[0014] In a possible implementation, the decorative part is an integrated structural part. That is, the fixing part, the protruding part and the extension part are integrally formed to form an integrated decorative part. This reduces the number of structural parts, simplifies the structural design, improves assembly efficiency, and helps reduce production costs and the difficulty of disassembly and maintenance. In addition, there is no need to perform additional sealing and ventilation design on the decorative part itself, which helps reduce the cost of waterproof and breathable design.

[0015] 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.

[0016] In a possible implementation, the size of the protrusion is smaller than the size of the through hole, so that the protrusion can pass through the through hole and protrude from the outer surface of the shell member. During assembly, the protrusion of the decorative member is passed through the through hole and protrudes from the shell member from the inner surface side of the shell member, and the fixing portion is fixed to the inner surface of the shell member to complete the assembly of the decorative member and the shell member. Compared with disassembling the decorative member into two independent structures and assembling them with the shell member respectively, the decorative member can be directly assembled to the shell member from the inner surface side of the shell member, realizing single-side assembly, which is simple in assembly and helps to improve assembly efficiency.

[0017] 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 protruding part 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 fixing the circumferential outer side surface of the fixing part to the inner surface of the shell part, which is beneficial to improving the assembly firmness of the decorative part and the shell part.

[0018] In a possible implementation, the housing assembly further includes a second air permeable channel, one end of the second air permeable channel is in communication with the interior of the chamber through the waterproof air permeable assembly, and the other end of the second air permeable channel is in communication with the external environment of the chamber. The second air permeable channel can also realize a gas passage between the interior and exterior of the chamber, and achieve air permeability while ensuring waterproof performance, thereby achieving the effect of balancing the air pressure inside and outside the electronic device. During the use of the electronic device, if the first air permeable channel is blocked or damaged, the second air permeable channel can ensure the air permeability of the electronic device, balance the internal and external air pressures and avoid problems such as pressing noise, significantly improving the reliability of the air permeability of the electronic device.

[0019] 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.

[0020] There is a third gap between the lens cover and the fixing part, and the second gap, the third gap and the waterproof breathable component are connected in sequence to form a second breathable channel. That is, one end of the second breathable channel is connected to the outside of the chamber through the second gap, and the other end of the second breathable channel is connected to the inside of the chamber through the waterproof breathable component, thereby realizing a gas passage between the inside and outside of the chamber, and also meeting the waterproof breathable requirements of electronic equipment.

[0021] In a possible implementation, the fixing portion includes a side wall and a top wall, and the side wall is disposed around a side of the top wall facing away from the protruding portion. A mounting seat is provided on a side of the top wall facing away from the protruding portion, and an assembly groove is provided on an end of the mounting seat facing away from the side wall, and the waterproof breathable component is fixed in the assembly groove. The mounting seat can match the size of the waterproof breathable component, and under the condition of meeting the assembly requirements, it is beneficial to reduce the occupied space and volume of the structure for assembling the waterproof breathable component, and it is beneficial to simplify the structure of the decorative part and reduce the weight of the decorative part.

[0022] The bottom of the assembly groove is provided with a first conducting groove, and the side wall is provided with a first vent hole, and the first vent hole is connected to the waterproof vent component in the assembly groove through the first conducting groove, thereby realizing the connection between the first vent hole and the waterproof vent component. That is, the waterproof vent component, the first conducting groove, the first vent hole, and the first gap are connected in sequence to form a first vent channel.

[0023] In a possible implementation, a second conducting groove is provided on the top wall, and the second conducting groove is in conduction with the third gap and the first conducting groove, so as to achieve conduction between the third gap and the waterproof breathable component. That is, the waterproof breathable component, the first conducting groove, the second conducting groove, the third gap and the second gap are sequentially connected to form a second breathable channel.

[0024] In a 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.

[0025] In one possible implementation, the outer side surface of the raised portion is an arc-shaped surface, so that the shell component has a "crater" design at the through hole position, and the shell component has a good ID appearance, which is beneficial to improving the aesthetics of the shell component and the electronic device.

[0026] In a possible implementation, the waterproof breathable component includes a waterproof breathable membrane and a first adhesive layer, the waterproof breathable membrane is fixed to the decorative element through the first adhesive layer, and a second air hole is provided on the first adhesive layer to communicate with the waterproof breathable membrane to meet the air permeability requirements of the waterproof breathable component.

[0027] In a possible implementation, the waterproof breathable assembly further includes a protective layer and a second adhesive layer, wherein the protective layer is located on a side of the waterproof breathable membrane that faces away from the first adhesive layer, and the second adhesive layer is located between the protective layer and the waterproof breathable membrane, and 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, thereby reducing or avoiding damage to the waterproof breathable membrane during the process of assembling the waterproof breathable assembly.

[0028] 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 component.

[0095] With the rapid development and widespread application of electronic equipment technology, the waterproof and airtight performance of electronic equipment is getting better and better. For example, IPX8 waterproof has gradually become a standard feature of flagship mobile phones on the market. Due to the good airtightness of electronic equipment, when the display screen and / or shell components of the electronic equipment are deformed by external force in scenarios such as pressing the touch screen or storing the electronic equipment, the air pressure inside the cavity of the electronic equipment will change, resulting in an imbalance in the air pressure inside and outside the electronic equipment, which will in turn cause an imbalance in the internal and external air pressure of audio devices such as speakers, causing problems such as pressing noise during playback of audio devices.

[0096] In order to realize the waterproof and breathable function of electronic equipment, a breathable channel can be set inside the electronic equipment, and a waterproof and breathable layer can be provided on the breathable channel, so that the environment inside and outside the electronic equipment chamber is connected through the breathable channel and the waterproof and breathable layer, and the balance of air pressure inside and outside the electronic equipment is achieved under the condition of meeting the waterproof performance. In addition, the waterproof and breathable layer and the breathable channel can also be used to realize waterproof and airtightness testing in the production of the whole machine.

[0097] In order to ensure the balance of internal and external air pressure of the electronic device, two air permeable channels can be formed on the shell assembly to avoid problems such as blockage of one air permeable channel during use, which may lead to air pressure imbalance.

[0098] Exemplarily, 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, and 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, and the appearance part is arranged around the lens cover plate.

[0099] There may be a first gap between the lens cover and the appearance part, and the first gap is connected to the environment outside the chamber. There may be a second gap between the lens cover and the structural part. The waterproof and breathable layer may be located on the structural part and is connected to the inside of the chamber. The waterproof and breathable layer, the second gap and the first gap are connected in sequence to form a first breathable channel. There may be a through-hole on the lens cover, and the waterproof and breathable layer, the second gap and the breathable hole are connected in sequence to form a second breathable channel.

[0100] However, the opening on the front side of the lens cover (the side facing away from the chamber) will affect the industrial design (ID) appearance of the housing assembly, affecting the aesthetics of the housing assembly and the electronic device. Moreover, the opening needs to be protected by a separate dust screen, which is costly. In addition, the decorative part is assembled from two independent structures, which is more complex in structure, has high production and design costs, is difficult to disassemble and repair, and a waterproof seal design is required between the two independent structures, which complicates the waterproof seal design.

[0101] In some other examples, the appearance part can cover part of the outer surface of the shell part, so that there is a third gap between the appearance part and the outer surface of the shell part, and the waterproof breathable layer, the second gap and the third gap are connected in sequence to form a second breathable channel. It is only applicable to the scene design where the appearance part covers part of the outer surface of the shell part, the scope of application is limited, and the assembly of two independent structures still has problems such as complex structure, complex waterproof sealing design, and difficult disassembly and maintenance.

[0102] Based on this, the embodiment of the present application provides a housing assembly, by assembling the decorative member on the through hole of the housing member, the waterproof and breathable assembly on the decorative member can be connected to the inside of the chamber surrounded by the inner surface of the housing member, a first air hole is formed on the decorative member, so that the first air hole can be connected to the outside of the chamber surrounded by the inner surface of the housing member, and the waterproof and breathable assembly is connected to the first air hole to form a first air permeable channel. That is, one end of the first air permeable channel is connected to the external environment of the chamber through the first air hole, and the other end of the first air permeable channel is connected to the inside of the chamber through the waterproof and breathable assembly, so as to realize the gas passage between the inside and outside of the electronic device chamber, and realize the ventilation effect under the condition of ensuring the waterproof performance, so as to balance the internal and external air pressure of the electronic device, so that the electronic device can have both waterproof and breathable performance, and avoid the problems such as pressing noise caused by the imbalance of internal and external air pressure of the electronic device, and the structural design is simple, the molding cost is low, the finished product yield is high, and it has better feasibility and wide applicability. The first air vent is located on the circumferential side of the decorative component, so that the housing assembly has a better ID appearance, and the aesthetics of the housing assembly and the electronic device are significantly improved.

[0103] Figure 3 This is an enlarged view of the local structure of a shell assembly provided in an embodiment of the present application.

[0104] See also Figure 3 As shown, the housing assembly 10 includes a housing member 11, a decorative member 13 and a lens cover plate 12. It should be noted that: Figure 3 Only a portion of the structure where the housing 11, the decorative component 13, and the lens cover plate 12 are assembled is shown.

[0105] The housing member 11 may also have an inner surface 11a and an outer surface 11b facing each other. The outer surface 11b and the inner surface 11a of the housing member 11 are respectively used to form part of the inner surface and part of the outer surface of the housing assembly 10, 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 facing away from the cavity. The outer surface 11b of the housing member 11 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.

[0106] The decorative member 13 is fixedly assembled on the housing member 11, and a portion of the decorative member 13 can be protruded from the outer surface 11b of the housing member 11 (combined with Figure 5 As shown), that is, the height of the decorative member 13 in the thickness direction (z direction) may be higher than the height of the outer surface 11b of the shell member 11 in the thickness direction (z direction).

[0107] The lens cover plate 12 is fixedly assembled on the decorative member 13. For example, the lens cover plate 12 can be located on one end of the decorative member 13 protruding from the housing member 11, and the decorative member 13 is arranged around the lens cover plate 12, so that the lens cover plate 12 can also be arranged protruding from the outer surface 11b of the housing member 11. Part of the camera module can also be arranged protruding from the outer surface 11b of the housing member 11, increasing the space for accommodating the camera module, so that the thickness of the electronic device at the position of the camera module (lens cover plate 12) can be greater than the thickness of the electronic device at other positions. Under the condition of meeting the thickness requirements of the entire device, the available space of the camera module is increased, which is conducive to enriching and improving the shooting performance of the electronic device.

[0108] 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.

[0109] For example, the decorative element 13 may be protruding from the lens cover plate 12 (combined with Figure 5 As shown), 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.

[0110] Figure 4 for Figure 3 Schematic diagram of the disassembled structure of the middle shell assembly.

[0111] See also Figure 4As shown, a through hole 111 may be opened on the shell member 11 , and the through hole 111 is used to realize the assembly of the decorative member 13 . The decorative member 13 may be arranged in the through hole 111 and fixedly assembled with the shell member 11 .

[0112] A first air hole 131 is provided on the decorative member 13 , and the first air hole 131 is used to form a first air passage to balance the air pressure inside the electronic equipment room and the external environment.

[0113] The shell assembly 10 further includes a waterproof breathable assembly 14 , which is disposed on the decorative member 13 . The waterproof breathable assembly 14 can pass gas and block liquid from passing through, and has breathable and waterproof properties.

[0114] It should be noted that a light-guiding through hole (not shown in the figure) may also be provided on the decorative member 13, and the light-guiding through hole may be arranged corresponding to the light-transmitting through hole on the lens cover plate 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.

[0115] The shape of the light-guiding through hole can match the shape of the lens of the camera module corresponding to the light-guiding through hole. For example, if the lens of the camera module is circular, the light-guiding through hole can also be circular. Exemplarily, the shape of the light-guiding through hole can be regular or irregular shapes such as circular, elliptical, track circular, square, etc.

[0116] Figure 5 for Figure 3 A schematic front view of the cross section of the middle shell assembly along the AA plane.

[0117] See also Figure 5 As shown, the waterproof breathable component 14 and the first air hole 131 can be arranged adjacent to a side edge of the decorative component 13, such as the waterproof breathable component 14 and the first air hole 131 can be located adjacent to the outer peripheral edge of the decorative component 13, thereby reducing the influence of the opening of the waterproof breathable component 14 and the first air hole 131 on the light-guiding through hole on the decorative component 13, thereby reducing or avoiding the influence on the layout design of the camera module, with high integration, which is conducive to the integrated setting of multiple camera modules.

[0118] Figure 6 for Figure 5 A magnified schematic diagram of the structure of part B.

[0119] See also Figure 6As shown, the decorative member 13 may be partially located in the through hole 111, with the side of the decorative member 13 opposite to the inner wall of the through hole 111 being the outer side surface 13a of the decorative member 13, that is, the inner wall of the through hole 111 surrounds the outer side surface 13a of the decorative member 13, and the outer side surface 13a of the decorative member 13 may be distributed along the circumference of the decorative member 13.

[0120] The first vent hole 131 of the decorative member 13 extends to the outer side surface 13a of the decorative member 13 (combined with Figure 4 As shown), the first air hole 131 is located on the circumferential side of the decorative member 13, and further see Figure 6 As shown, the first air hole 131 can be connected to the space located on the outer surface 11b side of the shell 11, that is, the first air hole 131 is connected to the environment outside the cavity of the electronic device.

[0121] The waterproof and breathable component 14 can be connected to the space located on the inner surface 11a side of the shell 11, such as the waterproof and breathable component 14 can be located on the side of the decorative component 13 facing the chamber, such as the waterproof and breathable component 14 is connected to the inside of the electronic device chamber, and the waterproof and breathable component 14 is connected to the first air hole 131 to form a first air permeable channel, such as the first air permeable channel S1 shown in the figure. That is, one end of the first air permeable channel S1 is connected to the environment outside the chamber through the first air hole 131, and the other end of the first air permeable channel S1 is connected to the inside of the chamber through the waterproof and breathable component 14, so as to realize the gas passage between the inside and outside of the electronic device chamber, and realize the ventilation effect under the condition of ensuring the waterproof performance, so as to balance the air pressure inside and outside the electronic device, so that the electronic device can have both waterproof and breathable performance, and avoid the problems such as pressing noise caused by the imbalance of air pressure inside and outside the electronic device. The first ventilation hole 131 is opened on the decorative member 13 to form the first ventilation channel S1. The structural design is simple. Compared with opening a hole on the lens cover plate 12, etc., it has better feasibility, lower molding cost and higher finished product yield.

[0122] In addition, compared with opening a hole on the front side of the lens cover plate 12, the first air hole 131 is opened on the outer side surface 13a of the decorative member 13 facing the inner wall surface of the through hole 111, that is, the first air hole 131 can be located on the circumferential side of the decorative member 13, so that the first air hole 131 is not easily observed from the appearance. And the first air hole 131 on the decorative member 13 has higher setting flexibility, such as the first air hole 131 can be located on the part of the decorative member 13 that does not protrude from the housing member 11, so that the first air hole 131 is hidden and invisible from the appearance, which significantly improves the aesthetics of the housing assembly and the electronic device.

[0123] 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.

[0124] 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 grooving 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.

[0125] The first air hole 131 is in communication with the external environment of the chamber. For example, the first air hole 131 may protrude from the outer surface 11b of the shell 11. For example, the first air hole 131 may extend to the portion of the decorative part 13 that protrudes from the shell 11, so that the first air hole 131 is exposed outside the shell 11 and the decorative part 13, thereby achieving communication between the first air hole 131 and the space on the outer surface side of the shell 11, thereby achieving communication between the first air hole 131 and the external environment of the chamber.

[0126] Alternatively, to further enhance the aesthetics of the housing assembly, illustratively, the first air hole 131 may not protrude from the outer surface 11b of the housing member 11, such as the height of the first air 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 air hole 131 extends to the portion of the decorative member 13 that is not protruding from the housing member 11. The first air hole 131 is hidden in the through hole 111 and is not exposed on the exterior surface of the housing assembly 10, so that the appearance of the first air passage opening is hidden and invisible, and the housing assembly 10 has a good ID appearance effect.

[0127] In the scenario where the first vent hole 131 is hidden, in order to achieve the connection between the first vent hole 131 and the outside of the chamber, for example, continue to refer to Figure 6As shown, there may be a first gap 132 between the outer side surface 13a of the decorative member 13 and the inner wall surface of the through hole 111, and the first gap 132 is connected to the space located on the outer surface 11b side of the shell member 11, and the first air hole 131 extending to the outer side surface 13a of the decorative member 13 can be connected to the first gap 132, so that the first air hole 131 can be connected to the outside of the chamber (the space on the outer surface side of the shell member 11) through the first gap 132. That is, the waterproof and breathable component 14, the first conducting groove 1335, the first air hole 131, and the first gap 132 are connected in sequence to form a first air permeable channel S1, one end of the first air permeable channel S1 is connected to the outside of the chamber through the first gap 132, and the other end of the first air permeable channel S1 is connected to the inside of the chamber through the waterproof and breathable component 14.

[0128] Figure 7 for Figure 3 Schematic diagram of the structure of the decorative parts in the shell assembly.

[0129] See also Figure 7 As shown, the decorative member 13 may include a protruding portion 134 and a fixing portion 133 connected to each other, and the fixing portion 133 is fixed to the inner surface of the housing. For example, taking the outer contour of the decorative member 13 as a circular structure, the outer contours of the protruding portion 134 and the fixing portion 133 may also be circular, and the fixing portion 133 may be located in the through hole 111 of the housing 11 (refer to Figure 6 As shown in FIG. 1 , the circumferential outer side surface of the fixing portion 133 may be opposite to the inner wall surface of the through hole 111 , and the circumferential outer side surface of the fixing portion 133 may form the outer side surface 13 a of the decorative member 13 .

[0130] For example, the circumferential outer side surface of the fixing portion 133 can be fixed to the inner surface of the shell 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, and the extension portion 135 can be an annular structural member, which can be bonded and fixed to the inner surface 11a of the shell member 11 through the extension portion 135 and the fixing portion 133, which is conducive to improving the fastness of the assembly and fixing of the decorative member 13 and the shell member 11.

[0131] 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, etc.

[0132] The protrusion 134 is arranged to protrude from the outer surface 11b of the housing 11 (see Figure 6 As shown), illustratively, the protrusion 134 can also be an annular structure, and the lens cover plate 12 can be set on the end of the protrusion 134 facing away from the fixing portion 133, and the protrusion 134 is arranged around the outer side of the lens cover plate 12.

[0133] The waterproof breathable component 14 and the first breathable hole 131 can be respectively arranged on the fixing portion 133 (refer to Figure 6 As shown), for example, the waterproof breathable component 14 is located on the side of the fixed portion 133 facing away from the protruding portion 134, the first air hole 131 and the waterproof breathable component 14 can be located on the fixed portion 133 at a position adjacent to the edge of one side of the fixed portion 133, and the first air hole 131 can extend to the circumferential outer surface of the fixed portion 133.

[0134] Continue to see Figure 7 As shown, the decorative part 13 can be an integrated structural part, that is, the fixing part 133, the protruding part 134 and the extension part 135 are integrally formed to form an integrated decorative part 13. For example, the integrated decorative part 13 having the protruding part 134, the fixing part 133 and the extension part 135 can be formed by mold preparation, computerized numerical control (CNC) and other processing. Reducing structural parts, simplifying structural design, improving assembly efficiency, and also helping to reduce production costs and the difficulty of disassembly and maintenance. There is no need to perform additional sealing and ventilation design on the decorative part 13 itself, which helps to reduce the cost of waterproof and breathable design.

[0135] In addition, the integrated decorative element 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.

[0136] Figure 8 for Figure 3 A schematic structural diagram of the middle shell assembly from another perspective of the cross section formed along the AA plane.

[0137] See also Figure 8 As shown, the size of the protrusion 134 of the decorative component 13 can be smaller than the size of the through hole 111 on the shell component 11. For example, taking the outer contours of the protrusion 134 and the fixing portion 133 as a circle, the centers of the protrusion 134, the through hole 111 and the fixing portion 133 can be projected to overlap 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 component 11.

[0138] During assembly, from the inner surface 11a side of the shell member 11, the protrusion 134 of the decorative component 13 is passed through the through hole 111 to protrude out of the shell member 11, and the fixing portion 133 is fixed to the inner surface 11a of the shell member 11 to complete the assembly of the decorative component 13 and the shell member 11. Compared with disassembling the decorative component 13 into two independent structures, the decorative component 13 can be directly assembled to the shell member 11 from the inner surface 11a side of the shell member 11, thereby realizing single-sided assembly. The assembly method is simple and is conducive to improving assembly efficiency.

[0139] Exemplarily, the size of the fixing portion 133 may be larger than the size of the through hole 111 on the shell member 11, for example, the radial size (or maximum radial size) of the fixing portion 133 may be larger than the radial size of the through hole 111. The fixing portion 133 cannot pass through the through hole 111 from the inner surface 11a side of the shell member 11. When the protrusion 134 is protruded through the through hole 111 from the inner surface 11a side of the shell member 11 during assembly, the fixing portion 133 may be clamped on the inner surface 11a side of the shell member 11 through the through hole 111, so as to facilitate the fixation between the circumferential outer side surface of the fixing portion 133 and the inner surface 11a of the shell member 11, thereby facilitating the assembly firmness of the decorative member 13 and the shell member 11.

[0140] 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 .

[0141] In order to ensure the balance of air pressure inside and outside the chamber of the electronic device, the housing assembly may also include a second air permeable channel, and the waterproof air permeable assembly is also located on the second air permeable channel. One end of the second air permeable assembly can be connected to the inside of the chamber through the waterproof air permeable assembly, and the other end of the second air permeable channel can be connected to the external environment of the chamber. The second air permeable channel can also realize the gas passage between the inside and outside of the chamber, and realize the air permeability under the condition of ensuring the waterproof performance, so as to achieve the effect of balancing the air pressure inside and outside the electronic device. During the use of the electronic device, if the first air permeable channel is blocked or damaged, the second air permeable channel can ensure the air permeability of the electronic device, balance the internal and external air pressures and avoid problems such as pressing noise, which significantly improves the reliability of the air permeability of the electronic device.

[0142] Fig. 9 for Figure 8 A partial enlarged view of the structure of part C in the middle.

[0143] For example, see Fig. 9 As shown, the lens cover plate 12 may be located on an end of the protruding portion 134 of the decorative element 13 facing away from the fixing portion 133 .

[0144] The protrusion 134 is arranged around the lens cover 12, and the circumferential inner side surface of the protrusion 134 (the side facing the internal hollow structure of the annular protrusion 134) is opposite to the circumferential outer side surface of the lens cover 12, so that a second gap 15 is provided 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 chamber.

[0145] There is a third gap 16 between the lens cover plate 12 and the fixing portion 133, and the second gap 15, the third gap 16 and the waterproof breathable component 14 are connected in sequence to form a second breathable channel, such as the second breathable channel S2 shown by the dotted line in the figure. That is, one end of the second breathable channel S2 is connected to the external environment of the chamber through the second gap 15, and the other end of the second breathable channel S2 is connected to the inside of the chamber through the waterproof breathable component 14, thereby realizing a gas passage between the inside and outside of the chamber, meeting the waterproof breathable requirements of the electronic device.

[0146] The connection between the waterproof and breathable component 14 on the fixing portion 133 and the third gap 16 can also be achieved by grooving the decorative member 13. For example, the decorative member 13 can also have a second conduction groove 1336. One end of the second conduction groove 1336 can extend to the side of the fixing portion 133 facing the lens cover plate 12. The other end of the second conduction groove 1336 can be connected to the waterproof and breathable component 14. For example, the other end of the second conduction groove 1336 can be connected to the waterproof and breathable component 14 through the first conduction groove 1335. That is, the waterproof and breathable component 14, the first conduction groove 1335, the second conduction groove 1336, the third gap 16, and the second gap 15 are connected in sequence to form the second breathable channel S2.

[0147] Fig.10 for Figure 7 Schematic diagram of the cross-sectional structure of the decorative part.

[0148] See also Fig.10 As shown, the fixing portion 133 of the decorative element 13 may include a top wall 1331 and a side wall 1332, wherein the side wall 1332 may be arranged 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.

[0149] Fig.11 for Figure 7 Another perspective structural diagram of the decorative parts.

[0150] See also Fig.11 As shown, 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 realize the assembly of the waterproof and breathable component.

[0151] The mounting seat 1333 can be arranged adjacent to the outer peripheral edge of the side wall 1332, and the mounting seat 1333 can be connected to the extension portion 135 to enhance the strength of the mounting seat 1333 and the entire decorative element 13, and enhance reliability. The waterproof and breathable component is assembled by the mounting seat 1333 protruding from the top wall 1331, and the mounting seat 1333 can match the size of the waterproof and breathable component. Under the condition of meeting the assembly requirements, it is beneficial to reduce the occupied space and volume of the structure for assembling the waterproof and breathable component, and it is beneficial to simplify the structure of the decorative element 13 and reduce the weight of the decorative element 13.

[0152] 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 .

[0153] 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 .

[0154] Fig.12 for Fig.10 A partial enlarged view of the structure of part D in the middle.

[0155] See also Fig.12 As shown, 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 accommodating 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.

[0156] 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 conduction with the first conducting groove 1335 .

[0157] Fig.13 for Figure 3 A schematic structural diagram of the cross section of the middle shell assembly formed along the AA plane from another perspective.

[0158] Combination Fig.13As shown, the other end of the second conducting groove 1336 can extend to the side of the top wall 1331 facing the lens cover plate 12, so that the other end of the second conducting groove 1336 can be connected to the third gap 16 between the lens cover plate 12 and the decorative member 13, so that the third gap 16 can be connected to the assembly groove 1334 and the waterproof breathable component 14 in the assembly groove 1334 through the second conducting groove 1336 and the first conducting groove 1335. The waterproof breathable component 14, the first conducting groove 1335, the first breathable hole 131 and the first gap 132 are connected in sequence to form a first breathable channel S1, and the waterproof breathable component 14, the first conducting groove 1335, the second conducting groove 1336, the third gap 16 and the second gap 15 are connected in sequence to form a second breathable channel S2.

[0159] In some examples, the shell member 11 may be a flat plate-shaped structural member, for example, the shell member 11 may be a rectangular flat plate-shaped structural member. It should be noted that the peripheral edge of the shell member 11 may be a plane, or the peripheral edge of the shell member 11 may be at least partially an arc-shaped surface with a certain curvature.

[0160] Or, in some examples, see Fig.13 As shown, the shell 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. The other end of the protrusion 113 can form a through hole 111 of the shell 11.

[0161] The main body 112 and the raised portion 113 can be integrally formed, so that the housing 11 is an integral structural member. Alternatively, in some examples, the main body 112 and the raised portion 113 can also be independently formed, and the raised portion 113 and the main body 112 can be assembled together to form the housing 11 by bonding, welding, clamping, etc.

[0162] 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.

[0163] The outer side surface 113a of the protrusion 113 is the side of the protrusion 113 facing away from the internal hollow structure. The outer side surface 113a of the protrusion 113 and the outer side surface of the shell 11 are used to form a part of the appearance surface of the shell assembly. The outer side surface 113a of the protrusion 113 can be a plane, for example, the outer side surface 113a of the protrusion 113 can be a plane extending in the thickness direction.

[0164] Alternatively, the outer side surface 113a of the protrusion 113 may be a curved surface, for example, Fig.13As shown, illustratively, the outer side surface 113a of the protrusion 113 can be an arc-shaped surface, so that the shell member 11 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.

[0165] In the embodiment of the present application, the structure of the waterproof breathable component 14 is not limited, as long as it can achieve waterproof performance and breathable performance. For example, the waterproof breathable component 14 can be a structural member composed of a waterproof breathable membrane layer and the like.

[0166] For example, see Fig.13 As shown, the waterproof breathable component 14 may include a waterproof breathable membrane 141 and a first adhesive layer 142, wherein the waterproof breathable membrane 141 has waterproof performance and breathable effect, allowing gas to pass through but liquid to not pass through. The waterproof breathable membrane 141 can be fixed to the decorative element through the first adhesive layer 142, for example, the waterproof breathable membrane 141 can be bonded and fixed to the bottom of the assembly groove of the mounting seat 1333 through the first adhesive layer 142.

[0167] It is understandable that in order to meet the ventilation requirements of the waterproof breathable component 14, a second ventilation hole 1421 can be opened on the first adhesive layer 142, and the second ventilation hole 1421 is connected to the waterproof breathable membrane 141. The position of the second ventilation hole 1421 can correspond to the position of the first conductive groove at the bottom of the assembly groove.

[0168] The waterproof breathable component 14 may further include a protective layer 143 and a second adhesive layer 144. The protective layer 143 is located on the side of the waterproof breathable membrane 141 that is opposite to the first adhesive layer 142, that is, the protective layer 143 and the first adhesive layer 142 are respectively located on the two opposite sides of the waterproof breathable membrane 141. The protective layer 143 can strengthen and protect the waterproof breathable membrane 141, reducing or avoiding damage to the waterproof breathable membrane 141 during the process of assembling the waterproof breathable component 14.

[0169] A second adhesive layer 144 may be provided between the protective layer 143 and the waterproof breathable membrane 141, so that the protective layer 143 can be fixed to the waterproof breathable membrane 141 through the second adhesive layer 144. Accordingly, in order to meet the ventilation requirements of the waterproof breathable component 14, a third air hole 1441 may be provided on the second adhesive layer 144, and a fourth air hole 1431 may be provided on the protective layer 143, and the third air hole 1441 and the fourth air hole 1431 are respectively connected to the waterproof breathable membrane 141.

[0170] It should be noted that the number of the second air hole 1421 on the first adhesive layer 142 , the third air hole 1441 on the second adhesive layer 144 , and the fourth air hole 1431 on the protective layer 143 may be one, or may be more than one.
