Description

Technical Field

[0001] This application relates to the field of electronic product technology, and in particular to a decorative part, housing assembly and electronic device. Background Technology

[0002] To prevent water from entering electronic devices such as mobile phones and tablets, the airtightness of these devices has been continuously improved. However, when the casing of an electronic device deforms due to external force, the air pressure inside the device changes, which can cause the diaphragm of audio devices to polarize, producing noise.

[0003] To address the issue of noise generated by audio components due to changes in internal air pressure in electronic devices, existing technologies typically involve creating ventilation holes in the camera trim on the back cover of the electronic device. These ventilation holes connect the inside and outside of the device, and a waterproof and breathable membrane is then placed over them. This membrane serves both waterproofing and ventilation purposes, while also balancing the air pressure inside and outside the electronic device, thus preventing noise from the audio components.

[0004] However, due to the limitations of the camera layout, the area of ​​the waterproof and breathable membrane cannot fully meet the requirements. Furthermore, if the ventilation channel connecting the vents to the outside is blocked, the ventilation will fail. Summary of the Invention

[0005] This application provides a decorative component, a housing assembly, and an electronic device. The camera module has an anti-shake function, and the decorative component adopts multiple balance valves and multiple venting paths to meet the venting requirements of the electronic device and effectively avoid venting failure.

[0006] In a first aspect, this application provides a decorative component for mounting on the housing of an electronic device, comprising a bracket, a cover plate, a first adhesive layer, and a balance valve;

[0007] The bracket includes a main board, a decorative ring, and a connecting part; the two sides of the main board are a first surface and a second surface, respectively, with the first surface facing the outer side of the housing and the second surface facing the inner side of the housing; the decorative ring protrudes from the periphery of the first surface, and a cover plate covers the first surface and forms a first vent gap with the decorative ring; the connecting part is connected to the periphery of the second surface and is used to connect with the housing; wherein, at least one receiving hole is provided on the main board, and a first adhesive layer is bonded between the cover plate and the main board and surrounds the periphery of the receiving hole;

[0008] The bracket has balance holes, including at least two first balance holes on the main board, and balance valves including first balance valves covering the first balance holes; at least two interconnected venting channels are formed between the main board and the cover plate, the first adhesive layer avoids the venting channels, the venting channels are connected to the first venting seam, and the first balance holes are connected to the venting channels.

[0009] The decorative component provided in this application features a bracket with multiple balancing holes and balancing valves covering them. This includes two or more first balancing holes spaced apart on the main board portion of the bracket, and first balancing valves covering these holes. Furthermore, multiple interconnected venting channels are formed in the area of ​​the main board portion where the first adhesive layer is not present. The ends of these venting channels extend to the edge of the main board portion and communicate with a first venting seam formed between the cover plate and the decorative ring. In this way, the electronic device can simultaneously vent through the multiple first balancing holes on the bracket, and gas inside the electronic device can leak out through any venting channel via the first venting seam. By employing a venting method with multiple balancing valves and multiple venting paths, the venting efficiency of the electronic device can be accelerated. Even if a balancing valve fails or some venting paths are blocked, venting can still occur through other balancing valves and venting paths, preventing venting failure.

[0010] In one possible implementation, the motherboard portion includes a first region and a second region located on both sides of the centerline of the motherboard portion, and a first balance hole is provided in both the first region and the second region.

[0011] By setting first balance holes in both the first and second regions on both sides of the center line of the main board of the bracket, the first balance holes on the main board are distributed to avoid the first balance valves being too concentrated, which could lead to the risk of all the first balance valves' venting paths being blocked, thus preventing venting failure and allowing for rapid pressure relief.

[0012] In one possible implementation, the first adhesive layer includes at least two mutually spaced-apart films, and the outer edges of the films extend to the edge of the main board portion;

[0013] The venting channel includes at least two first venting channels, which extend from the middle of the main board to the edge, and the first balance hole is located in the middle area of ​​the first venting channel.

[0014] In one possible implementation, the first adhesive layer includes a film, and the edge of the film includes a notch segment located between adjacent first balance holes and spaced from the edge of the main board portion;

[0015] The venting channel includes at least two second venting channels formed between the recessed section and the decorative ring. The second venting channels extend along the periphery of the main plate and communicate with the adjacent first balance hole.

[0016] In one possible implementation, the first adhesive layer includes at least two mutually spaced-apart films, and the edge of the film near the edge of the main board portion includes a notch segment, the notch segment being located between adjacent first balance holes and having a gap with the edge of the main board portion.

[0017] The venting channel includes at least one first venting channel and at least one second venting channel. The first venting channel extends from the middle of the main board portion to the edge, and the second venting channel extends along the periphery of the main board portion and communicates with the adjacent first balance hole.

[0018] In one possible implementation, the decorative ring is provided with at least one stepped groove, which is correspondingly provided with the end of the first venting channel;

[0019] The stepped groove extends from the inner wall of the decorative ring to the outer wall and connects to the top surface of the decorative ring.

[0020] By setting a stepped groove on the decorative ring that corresponds to the first venting channel, the stepped groove extends from the inner wall of the decorative ring to the outer wall and connects to the top surface of the decorative ring. In this way, the width of the part of the first venting slot corresponding to the end of the first venting channel is increased by the stepped groove, the venting area of ​​the first venting slot is increased, and the venting efficiency of the electronic device is accelerated.

[0021] In one possible implementation, the connecting portion includes a sidewall and an overlapping edge. The sidewall is connected to the periphery of the second surface and extends toward the housing. The overlapping edge is connected to one end of the sidewall away from the main board portion and is connected to the housing.

[0022] By setting sidewalls, the volume of the decorative parts is increased, allowing the main board to protrude from the outer surface of the housing. The space between the main board and the housing provides additional accommodation space, providing ample installation space for the camera module.

[0023] In one possible implementation, at least one air guide groove is provided on the side wall. The opening of the air guide groove is located on the first surface and communicates with the venting channel. The air guide groove extends to the side where the overlap is located and communicates with the outside.

[0024] By opening a venting groove on the side wall, the opening of the venting groove is located on the first surface of the main board of the bracket and communicates with the venting channel. The venting groove extends to the side of the overlap and communicates with the outside. In this way, in addition to venting out through the first venting seam, the air inside the electronic device can also vent out through the venting channel and the venting groove, which increases the venting path of the electronic device and reduces the risk of venting failure.

[0025] In one possible implementation, a first vent hole is also provided on the side wall, the first vent hole is exposed outside the housing and extends from the outer wall surface of the side wall to communicate with the air guide groove.

[0026] By opening a first vent hole on the side wall that communicates with the vent groove, the gas inside the electronic device flows through the vent channel to the vent groove, then enters the first vent hole from the vent groove, and can flow directly to the outside through the first vent hole.

[0027] In one possible implementation, the overlap edge is fitted to the side surface of the housing facing the inside of the electronic device, and the side wall extends outward from the electronic device through a mounting hole provided on the housing;

[0028] A second venting gap is formed between the side wall and the wall of the mounting hole, and the air guide groove is connected to the second venting gap.

[0029] By connecting the overlapping edge of the decorative bracket to the inner surface of the housing, and extending the sidewall of the bracket outward from the mounting hole of the housing, the appearance of the electronic device can be improved. The housing's stop and limit mechanism also enhances the connection stability of the bracket. Furthermore, a second venting slot is formed between the sidewall of the bracket and the wall of the mounting hole. By connecting the venting groove on the sidewall to the second venting slot, in addition to venting outward through the first venting slot, air inside the electronic device can also vent outward through the venting channel, venting groove, and second venting slot, increasing the venting paths of the electronic device and reducing the risk of venting failure.

[0030] In one possible implementation, a connecting groove is also provided on the side wall, the connecting groove is corresponding to the wall of the mounting hole, and the two ends of the connecting groove are respectively connected to the air guide groove and the second air vent.

[0031] The air guide groove on the side wall extends into the housing. A connecting groove corresponding to the wall of the mounting hole is opened on the side wall. The opening of the connecting groove extends from the outer wall surface of the side wall to connect with the air guide groove, so as to connect the air guide groove and the second venting gap through the air guide groove.

[0032] In one possible implementation, the top wall of the connecting groove near the first surface is higher than the plane containing the outer surface of the housing.

[0033] By making the top wall of the connecting groove higher than the plane of the outer surface of the housing, the top area of ​​the connecting groove is exposed outside the housing, which is equivalent to increasing the width of the second venting slit at the location of the connecting groove, increasing the venting area of ​​the second venting slit, and improving the venting efficiency of the electronic device.

[0034] In one possible implementation, the overlap has at least one extension that extends outward from the support, and at least one air passage is formed between the extension and the inner surface of the housing, the air passage extending to the sidewall and communicating with the venting passage.

[0035] The balance orifice also includes at least one second balance orifice opened on the extended portion, the second balance orifice being located within the air guide passage, and the balance valve also includes a second balance valve covering the second balance orifice.

[0036] By adding an extension on the overlap edge of the bracket, an air guide channel is formed between the extension and the inner surface of the housing, which communicates with the air venting channel. A second balance hole is opened on the extension, located within the coverage area of ​​the air guide channel. A second balance valve is covered on the second balance hole. With more balance valves and more air venting paths, air venting failure can be avoided and air venting efficiency can be improved.

[0037] In one possible implementation, the extension portion includes at least two, and the extension portions are circumferentially spaced along the overlap edge, and each extension portion has at least one second balancing hole.

[0038] By setting two or more extended portions circumferentially at intervals along the overlap edge, and opening a second balancing hole on each extended portion, and having a second balancing valve covering each second balancing hole for outward venting, the electronic equipment can vent through multiple balancing valves and multiple venting paths, thus avoiding venting failure. At the same time, this increases the venting area of ​​the electronic equipment and accelerates its venting efficiency.

[0039] In one possible implementation, the extension portion is an annular portion, and at least two second balancing holes are provided on the extension portion at circumferential intervals.

[0040] By setting the extension portion as a ring structure, two or more second balance holes can be arranged circumferentially on the ring-shaped extension portion. This increases the number of second balance valves, the number of venting points, the venting area, and the venting efficiency. Electronic equipment can vent externally through multiple balance valves and multiple venting paths, thus avoiding venting failure.

[0041] In one possible implementation, the second balance hole includes at least one second balance hole disposed in the circumferential direction of the support corresponding to the air guide groove.

[0042] By aligning the second balance hole with the air guide groove on the side wall of the bracket, the air guide channel connected to the second balance hole is directly connected to the air guide groove. After passing through the second balance valve, the gas inside the electronic device enters the air guide groove directly through the air guide channel and then enters the venting channel.

[0043] In one possible implementation, the second balancing hole includes at least one second balancing hole that is offset from the air guide groove in the circumferential direction of the support.

[0044] By offsetting the second balance hole and the air guide groove on the side wall of the bracket, the gas inside the electronic device flows through the second balance valve and then flows in the annular air guide channel around the side wall of the bracket until it flows to the corresponding air guide groove on the side wall, and then enters the venting channel through the air guide groove.

[0045] In one possible implementation, the sidewall includes an inner extension that protrudes from the inner wall of the sidewall toward the center of the support, and an air guide groove is formed on the inner extension.

[0046] By adding an inner extension to the sidewall, which protrudes inward from the inner wall surface, the thickness of the sidewall is increased without affecting the shape and dimensions of the outer wall surface. To meet the requirements for the air guide groove, the air guide groove can be formed on the inner extension.

[0047] In one possible implementation, a plurality of air guide grooves are provided on the side wall, and the plurality of air guide grooves are arranged at intervals along the circumference of the side wall.

[0048] By setting multiple air guide grooves at circumferential intervals on the side wall, all of which are connected to the venting channel, the gas inside the electronic device can be vented outward through any air guide groove. The increased venting path reduces the risk of venting failure caused by blockage of one or more venting paths while ensuring the amount of venting.

[0049] In one possible implementation, the cover plate has at least one second vent hole, which is connected to the venting channel, and the second vent hole is covered with a decorative mesh.

[0050] By creating a second vent hole on the cover plate, which connects to the venting channel, gas inside the electronic device can escape through the second vent hole. Covering the second vent hole with a decorative mesh serves to allow air to pass through, prevent foreign objects from entering, and also enhances the aesthetic appeal.

[0051] In one possible implementation, the orthographic projection of the second vent hole on the main board portion lies within the coverage area of ​​the first balance hole.

[0052] By positioning the projection of the second vent hole onto the main board within the coverage area of ​​the first balance hole, and with the second vent hole directly opposite the first balance valve, the venting path between the two is short, resulting in high venting efficiency.

[0053] In one possible implementation, the decorative mesh includes an inset portion and an outer ring portion surrounding the periphery of the inset portion;

[0054] The inner part protrudes from the side of the outer ring facing the cover plate, and the inner part is embedded in the second vent hole, while the outer ring is attached to the side surface of the cover plate facing the main plate.

[0055] The decorative mesh is attached to the inner surface of the cover plate through the outer ring, which ensures that the decorative mesh is firmly connected and does not affect the flatness of the outer surface of the cover plate; the embedded part is embedded in the second vent hole to provide ventilation and dust prevention, and also to achieve a decorative effect.

[0056] In one possible implementation, the top surface of the inset portion facing away from the outer ring portion is flush with the surface of the cover plate.

[0057] In one possible implementation, the balance hole includes at least one main balance hole located in an easily pressable area on the bracket.

[0058] A main balance hole is set in the easily pressable area on the bracket, and a main balance valve is covered on the main balance hole. The easily pressable area is a high-frequency pressing area, and the air pressure in this area of ​​the electronic device is prone to increase. The main balance valve in this area quickly releases the pressure inside the electronic device.

[0059] In one possible implementation, the area of ​​the main balancing hole is larger than the area of ​​the other balancing holes.

[0060] Compared to other balance holes, by increasing the area of ​​the main balance hole, the area of ​​the main balance valve covering the main balance hole is larger, and the main balance valve has a faster venting efficiency, which helps to quickly release the pressure inside the electronic equipment.

[0061] In one possible implementation, the balancing valve covers the side surface of the bracket facing inwards from the electronic device, or the balancing valve covers the side surface of the bracket facing outwards from the electronic device.

[0062] In one possible implementation, the balancing valve includes a waterproof and breathable membrane or a dustproof mesh.

[0063] Secondly, this application provides a housing assembly for mounting on an electronic device, including a housing and the decorative element as described above;

[0064] The decorative element is located on the side of the housing facing outwards from the electronic device. The housing has mounting holes, the decorative element covers the mounting holes, and is connected to the portion of the housing located on the outer periphery of the mounting holes.

[0065] The housing assembly provided in this application includes a housing and a decorative element mounted on the housing. The decorative element has multiple balancing holes on a bracket and balancing valves covering the balancing holes. This includes two or more first balancing holes spaced apart on the main board portion of the bracket, and first balancing valves covering the first balancing holes. Furthermore, multiple interconnected venting channels are formed in the area on the main board portion where the first adhesive layer is not provided. The ends of the venting channels extend to the edge of the main board portion and communicate with a first venting seam formed between the cover plate and the decorative ring. Thus, the electronic device can vent simultaneously through the multiple first balancing holes on the bracket, and gas inside the electronic device can leak out through any venting channel via the first venting seam. By employing a venting method with multiple balancing valves and multiple venting paths, the venting efficiency of the electronic device can be accelerated. Even if a balancing valve fails or some venting paths are blocked, venting can still occur through other balancing valves and venting paths, thus preventing venting failure.

[0066] In one possible implementation, the housing assembly further includes a second adhesive layer bonded between the decorative element's connection and the housing.

[0067] In one possible implementation, the overlapping edge of the connector fits against the side surface of the housing facing the inside of the electronic device, and the sidewall of the connector extends outward from the mounting hole into the electronic device.

[0068] The second adhesive layer is bonded between the overlap edge and the housing, and the second adhesive layer is positioned close to the outer edge of the overlap edge.

[0069] Thirdly, this application provides an electronic device, including a screen, a mid-frame, an audio device, and a housing assembly as described above;

[0070] The mid-frame includes a frame and a support plate. The frame surrounds the periphery of the support plate, and the screen and housing assembly are respectively connected to the two sides of the mid-frame.

[0071] The support plate and the housing of the housing assembly form a receiving space, and the audio device is installed in the receiving space; wherein, the support plate has a sound outlet, and the sound outlet surface of the audio device is exposed in the sound outlet.

[0072] The electronic device provided in this application includes a housing assembly, which comprises a housing and a decorative element mounted on the housing. The decorative element has multiple balancing holes on a bracket and balancing valves covering the balancing holes. The bracket has two or more first balancing holes spaced apart on its main board portion, and first balancing valves covering the first balancing holes. Furthermore, multiple interconnected venting channels are formed in the area of ​​the main board portion where no first adhesive layer is provided. The ends of the venting channels extend to the edge of the main board portion and communicate with a first venting seam formed between the cover plate and the decorative ring. Thus, the electronic device can vent simultaneously through the multiple first balancing holes on the bracket, and gas inside the electronic device can leak out through any venting channel via the first venting seam. By employing a venting method with multiple balancing valves and multiple venting paths, the venting efficiency of the electronic device can be accelerated. Even if a balancing valve fails or some venting paths are blocked, venting can still occur through other balancing valves and venting paths, thus preventing venting failure.

[0073] In one possible implementation, the electronic device further includes a camera module, which is installed within the receiving space;

[0074] The camera module includes at least one camera, the light-incident end of which is exposed within a receiving hole in the decorative element of the housing assembly.

[0075] In electronic devices, the camera module is installed within a space formed by the support plate and decorative parts of the mid-frame. The camera, flash, sensors, and other components in the camera module are positioned corresponding to receiving holes created in the decorative parts. Taking the camera as an example, the light-receiving end of the camera is exposed within the receiving hole to facilitate the camera's acquisition of ambient light. Attached Figure Description

[0111] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0112] With the development of communication technology, the overall design of mobile terminals such as smartphones and tablets is becoming increasingly thinner and lighter, resulting in better grip and a more aesthetically pleasing appearance. Meanwhile, to enhance the camera performance of mobile terminals, the camera modules they are equipped with are becoming increasingly powerful, and these powerful camera modules tend to be larger. To accommodate these bulky camera modules within thinner and lighter mobile terminals, more and more mobile terminals are incorporating decorative elements on their casings. These decorative elements protrude from the outer surface of the casing, providing more installation space for the camera module. Furthermore, these decorative elements facilitate the centralized layout of multi-camera camera modules and also enhance the aesthetics of the mobile terminal.

[0113] Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. (Refer to...) Figure 1As shown, the electronic device 1 of this embodiment will be described using a mobile phone as an example. It should be understood that the electronic device 1 of this embodiment can also be a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a smart wearable device, a point of sale (POS) terminal, an augmented reality (AR) / virtual reality (VR) device, or other mobile terminal devices.

[0114] Figure 1 The structure of the housing assembly 10 of the electronic device 1 is shown from the rear view. The housing assembly 10 includes a housing 200 and a decorative element 100 mounted on the housing 200. The housing 200 is equivalent to the back cover of the electronic device 1. The decorative element 100 is located on the outer surface of the housing 200 and can protrude outward from the outer surface of the housing 200. The area covered by the decorative element 100 can be used to arrange a camera module (not shown in the figure). The side of the decorative element 100 facing away from the housing 200 (the side facing outward from the electronic device 1) is light-transmitting, so that external light can pass through the decorative element 100 and illuminate the camera module.

[0115] The outer surface of the housing 200 refers to the side of the housing 200 facing the outside of the electronic device 1, and the other side of the housing 200 opposite to the outer surface is the inner surface. The inner surface of the housing 200 faces the inside of the electronic device 1.

[0116] The electronic device 1 also includes a screen (not shown) and a mid-frame 30. The screen is located on the opposite side from the housing assembly 10. The mid-frame 30 surrounds the housing assembly 10 and the screen, and the screen and housing assembly 10 are respectively connected to the two sides of the mid-frame 30, which supports and fixes the screen and housing assembly 10. The screen, mid-frame 30, and housing assembly 10 together form a receiving space for the electronic device 1, which is used to accommodate devices such as a camera module, motherboard (not shown), battery (not shown), and audio devices (not shown).

[0117] Figure 2 for Figure 1 An exploded view of the electronic equipment in the image. (Refer to...) Figure 2As shown, in this embodiment, the side of the middle frame 30 facing the screen 20 is defined as the front side of the middle frame 30, and the side of the middle frame 30 facing the housing 200 is defined as the rear side of the middle frame 30. In practical applications, the middle frame 30 typically includes a frame body 301 and a support plate 302. The frame body 301 surrounds the periphery of the housing assembly 10 and the screen 20. The support plate 302 is located within the area surrounded by the frame body 301 and is connected to the inner wall of the frame body 301 (the wall surface located on the inner peripheral edge of the frame body 301). For example, the support plate 302 can be integrally formed with the frame body 301.

[0118] The screen 20 is connected to the front side of the mid-frame 30. The screen 20 can be attached to the surface of the support plate 302. The support plate 302 supports the screen 20, ensuring a stable connection between the screen 20 and the mid-frame 30 and preventing the screen 20 from collapsing. For example, the screen 20 is bonded to the support plate 302 by a screen adhesive layer 40. The screen adhesive layer 40 can be a ring-shaped frame adhesive as shown in the figure, or the screen adhesive layer 40 can also cover a large area of ​​the support plate 302 to improve the connection strength of the screen 20.

[0119] The housing 200 is connected to the rear side of the middle frame 30. The housing 200 has mounting holes 210. A decorative piece 100 covers the mounting holes 210 and connects to the area on the housing 200 located around the mounting holes 210. The decorative piece 100 can protrude from the outer surface of the housing 200. The edge area of ​​the inner surface of the housing 200 can be supported and fixed to the frame 301. For example, the edge area of ​​the inner surface of the housing 200 can be bonded to the frame 301 using frame adhesive (not shown). There is a gap between the housing 200 and the support plate 302. The frame 301, the support plate 302, and the housing 200 together form a space for accommodating the electronic device 1. Devices such as a camera module (not shown), a motherboard (not shown), a battery (not shown), and an audio device 50 can be installed in the space between the support plate 302 and the housing 200.

[0120] Among them, reference Figure 2 As shown, a sound outlet 3021 is provided on the support plate 302, and an audio device 50 is disposed corresponding to the sound outlet 3021. For example, a limiting wall 3022 can be provided on the area around the sound outlet 3021 on the support plate 302. The audio device 50 is secured within the area enclosed by the limiting wall 3022. Furthermore, a sealing part 60 is provided between the audio device 50 and the support plate 302. The sealing part 60 can, for example, be arranged around the periphery of the audio device 50, and the audio device 50 is sealed to the support plate 302 through the sealing part 60. The audio device 50 can be, for example, a handset or a speaker. The sound-emitting surface of the audio device 50 is exposed within the sound outlet 3021. The side of the audio device 50 facing the screen 20 is the front cavity, and the side facing the housing 200 is the rear cavity.

[0121] The camera module includes one or more cameras, and can be a single-camera module, a dual-camera module, or a multi-camera module (including three or more cameras). Furthermore, the cameras in the camera module include, but are not limited to, at least one of the following: autofocus (AF) cameras, fixed-focus (FF) cameras, wide-angle cameras, telephoto cameras, color cameras, or monochrome cameras. Additionally, the camera module may also include other components such as a flash and sensors (e.g., a color temperature sensor).

[0122] The camera module is installed within the coverage area of ​​the decorative component 100. The positions of each camera in the camera module can be arranged according to layout design requirements, and the structure of the decorative component 100 can be configured based on the layout design of the camera module. Figure 2 The outline shape shown is not limited to a circular decorative element 100. For example, one or more cameras in the camera module may include a camera located at the center of the decorative element 100, or cameras spaced circumferentially along the decorative element 100.

[0123] In practical applications, the outline shape of the decorative part 100 of the electronic device 1 is not limited to a circle, but can also be a square or a rectangle or other shapes. The layout design of the camera module can be carried out according to the outline shape of the decorative part 100. Figure 3 This is a rear view of another electronic device provided in an embodiment of this application. Figure 3 The decorative part 100 of the electronic device 1 shown in the figure has a square outline shape, and the cameras in the camera module can be arranged in rows and columns at intervals along the width and length directions of the housing 200; Figure 4 This is a rear view of a third type of electronic device provided in an embodiment of this application. Figure 4 The decorative part 100 of the electronic device 1 shown in the figure has a rectangular outline. The cameras in the camera module can be arranged in columns along the length of the housing 200. Depending on the actual width of the decorative part 100, one, two or more columns of cameras can be set.

[0124] Additionally, refer to Figure 1 , Figure 3 and Figure 4 As shown, based on the internal layout and external structure design of the electronic device 1, the decorative component 100 can be located in the middle area of ​​the width direction of the electronic device 1. For example, the decorative component 100 can be symmetrical about the center line of the length direction of the electronic device 1. Alternatively, the decorative component 100 can be disposed off from the center of the width direction of the electronic device 1. For example, the decorative component 100 can be disposed close to one edge of the width direction of the electronic device 1.

[0125] In practical applications, to prevent water ingress into electronic device 1, the airtightness of the entire device is continuously being strengthened. Most existing electronic devices 1 can achieve an IPX7 protection rating, where "X" represents the dustproof rating and "7" represents the waterproof rating, indicating that the electronic device 1 can provide its internal components with at least 30 minutes of protection when submerged in water at a depth of more than 1 meter. For electronic devices 1 with high airtightness, when the casing 200 of electronic device 1 is pressed, the air pressure inside electronic device 1 will change accordingly.

[0126] Combination Figure 1 and Figure 2 As shown, since the middle frame 30 and the housing assembly 10 form an accommodating space, and there is a certain gap between the support plate 302 of the middle frame 30 and the housing 200, when the electronic device 1 is pressed, the air pressure in the space between the support plate 302 and the housing 200 mainly changes. Since the audio device 50 is installed in the accommodating space formed between the middle frame 30 and the housing 200, when the housing 200 is pressed, the change in air pressure in the accommodating space will cause the diaphragm of the audio device 50 to polarize, generating noise.

[0127] Therefore, in related technologies, a vent is typically created on the decorative component, which connects to the outside through a venting channel. A waterproof and breathable membrane is then covered over the vent. This membrane serves a waterproof function while allowing air to circulate inside and outside the electronic device, balancing the air pressure and preventing diaphragm polarization in audio components, thus preventing noise generation.

[0128] However, due to the size limitations of the decorative components, the area of ​​a single vent is small, and the air leakage capacity of the waterproof and breathable membrane covering the vent cannot fully meet the air leakage requirements of electronic devices. In addition, if the waterproof and breathable membrane or air leakage channel is blocked by dust or other foreign objects, the displacement and air leakage path connecting the housing space of the electronic device to the outside world will be blocked, causing the entire device to fail to leak air.

[0129] To address this, this embodiment designs the structure of the decorative component 100 so that it vents air through multiple balancing valves and multiple venting paths. All venting paths are interconnected, and each balancing valve can vent air through all venting paths. The venting capacity of the decorative component 100 can meet the venting requirements of the electronic device 1. Furthermore, by adding venting redundancy, in the event of failure of a single balancing valve or blockage of some venting paths, venting can be achieved through other balancing valves and venting paths, thus preventing venting failure.

[0130] The following provides a detailed description of the specific structure of the decorative part 100 and the venting path formed between the decorative part 100 and the housing 200.

[0131] Example 1

[0132] Figure 5 This is a schematic diagram of the structure of a decorative component provided in an embodiment of this application; Figure 6 for Figure 5 Exploded view of the decorative elements in the image;

[0133] Figure 7 for Figure 1 A partial cross-sectional diagram of AA. It should be noted that... Figure 5 The text shows the relationship with... Figure 1 The decorative element 100 matches the electronic device 1 in the middle, and the overall outline shape of the decorative element 100 is circular. It is understood that, as previously stated, in combination with... Figure 3 and Figure 4 As shown, the overall outline shape of the decorative part 100 can be a square or a rectangle or other shapes. This embodiment does not impose specific restrictions on this. The following description will use a decorative part 100 with a circular outline as an example.

[0134] Reference Figure 5 and Figure 6 As shown, the main structure of the decorative element 100 includes a bracket 110 and a cover plate 120. Combined with... Figure 7 As shown, the bracket 110 is connected to the housing 200. For example, the bracket 110 can be connected to the area on the housing 200 located around the mounting hole 210, and the decorative element 100 is mounted and fixed to the housing 200 through the bracket 110. The cover plate 120 is provided on the side of the bracket 110 facing away from the housing 200, that is, the cover plate 120 faces outward of the electronic device 1. The cover plate 120 can be a highly transparent glass cover plate 120 or a plastic cover plate 120, so that external light can pass through the cover plate 120 and shine into the interior of the decorative element 100, so that the camera module installed between the decorative element 100 and the middle frame 30 can receive external light.

[0135] Additionally, refer to Figure 7 As shown, a sound outlet slit c is formed between the top of the screen 20 and the front side of the frame 301 of the middle frame 30. The sound outlet 3021 on the support plate 302 of the middle frame 30 is connected to the sound outlet slit c. The sound emitted by the audio device 50 is transmitted to the outside through the sound outlet slit c from the front cavity.

[0136] Figure 8a for Figure 5 The diagram shows the main structural view of the support for the decorative element 100. Referring to FIG8, the support 110 of the decorative element 100 includes a main board portion 111, a decorative ring 112, and a connecting portion. For example, the main board portion 111, the decorative ring 112, and the connecting portion can be integrally molded parts, that is, the support 110 is an integrally molded structure.

[0137] The main board portion 111 is, for example, a plate-shaped structure that matches the mounting holes 210 of the housing 200. Taking the mounting holes 210 on the housing 200 as circular mounting holes 210 as an example, the main board portion 111 can be a circular plate-shaped structure. The decorative part 100 mainly covers the mounting holes 210 of the housing 200 through the main board portion 111. The two side surfaces of the main board portion 111 are a first surface and a second surface, respectively. The first surface is the side of the main board portion 111 facing outwards from the electronic device 1, and the second surface is the side of the main board portion 111 facing inwards from the electronic device 1.

[0138] A decorative ring 112 protrudes from the first surface of the motherboard portion 111 and surrounds the periphery of the motherboard portion 111. A cover plate 120 covering the first surface of the motherboard portion 111 can be located within the area surrounded by the decorative ring 112, with the decorative ring 112 limiting the position of the cover plate 120. Furthermore, the decorative ring 112 is the main structure of the decorative component 100 exposed to the outside of the electronic device 1, excluding the cover plate 120. The cover plate 120 primarily serves a light-transmitting and protective function, while the decorative ring 112 serves a decorative function.

[0139] The connecting part is connected to the periphery of the second surface of the motherboard part 111, and is combined with Figure 7 and Figure 8a As shown, the connecting portion is used to connect with the area on the housing 200 located around the mounting hole 210 to fix the bracket 110 to the housing 200. Specifically, the connecting portion may include a side wall 113 and an overlapping edge 114. The side wall 113 is connected to the periphery of the second surface of the main board portion 111 and extends away from the main board portion 111 (towards the housing 200). The overlapping edge 114 is connected to one end of the side wall 113 away from the main board portion 111, and the overlapping edge 114 can be fitted and connected to the housing 200. By setting the side wall 113, the spatial volume of the decorative member 100 is increased, allowing the main board portion 111 to protrude outward from the outer surface of the housing 200. The space between the main board portion 111 and the housing 200 provides additional accommodating space, providing ample installation space for the camera module.

[0140] In some embodiments, the bracket 110 can be connected to the outer surface of the housing 200, that is, the overlapping edge 114 of the bracket 110 is connected to the area on the outer surface of the housing 200 located around the mounting hole 210. In this case, the bracket 110 is completely exposed outside the housing 200. The overlapping edge 114 of the bracket 110 can be an inwardly flanged structure, formed by the overlapping edge 114 extending inward from the sidewall 113 (extending towards the center of the bracket 110), or the overlapping edge 114 of the bracket 110 can be an outwardly flanged structure, formed by the overlapping edge 114 extending outward from the sidewall 113 (extending towards the periphery of the bracket 110).

[0141] Reference Figure 7As shown, in some embodiments, the bracket 110 can be connected to the inner surface of the housing 200, that is, the overlapping edge 114 of the bracket 110 is connected to the area on the inner surface of the housing 200 located around the mounting hole 210. In this case, the overlapping edge 114 of the bracket 110 is located inside the housing 200, and the overlapping edge 114 of the bracket 110 can be the aforementioned outwardly flanged structure. The side wall 113 of the bracket 110 extends outward through the mounting hole 210 on the housing 200, so that the bracket 110 protrudes on the outer surface of the housing 200. This method facilitates the positioning of the decorative part 100, and since the overlapping edge 114 of the bracket 110 is located inside the electronic device 1, it does not affect the appearance of the electronic device 1. By limiting the overlapping edge 114 of the bracket 110 by the inner surface of the housing 200, the connection strength of the decorative part 100 can also be improved. The following description uses the example of the overlapping edge 114 of the bracket 110 being connected to the inner surface of the housing 200.

[0142] Reference Figure 6 and Figure 7 As shown, the connection between the cover plate 120 and the main board portion 111 of the bracket 110 is achieved by providing a first adhesive layer 130 between the first surfaces of the cover plate 120 and the main board portion 111, thereby bonding the cover plate 120 to the first surface of the main board portion 111 of the bracket 110. Regarding the connection between the overlapping edge 114 and the housing 200, a second adhesive layer 180 can be provided between the overlapping edge 114 and the housing 200. The second adhesive layer 180 can be an annular adhesive layer bonded between the overlapping edge 114 of the bracket 110 and the inner (outer) surface of the housing 200.

[0143] In addition, in this embodiment, the screen adhesive layer 40 bonded between the screen 20 and the middle frame 30, the frame adhesive bonded between the inner surface of the housing 200 and the middle frame 30, the first adhesive layer 130 bonded between the cover plate 120 and the bracket 110, and the second adhesive layer 180 bonded between the overlap edge 114 of the bracket 110 and the inner surface (outer surface) of the housing 200 can all be a back adhesive layer formed by double-sided adhesive layers, or a dispensing layer formed by dispensing process, or an adhesive layer formed by combining a back adhesive layer and a dispensing layer.

[0144] Reference Figure 8aAs shown, the main board portion 111 of the bracket 110 of the decorative component 100 is provided with a receiving hole 1111. Components in the camera module that need to receive light or emit light are exposed within the receiving hole 1111, enabling them to receive external light or emit light. For example, if the camera module includes only one camera, the main board portion 111 of the bracket 110 may have only one receiving hole 1111, with the light-incident end of the camera exposed within this hole. If the camera module includes two or more cameras, the main board portion 111 of the bracket 110 may have two or more receiving holes 1111, with the light-incident end of each camera corresponding to a specific receiving hole 1111. Furthermore, in addition to the camera, for camera modules that also include components such as a flash and a sensor, the multiple receiving holes 1111 provided on the main board portion 111 of the bracket 110 may also include receiving holes 1111 corresponding to the flash and sensor.

[0145] It should be noted that, Figure 8a The shape of the receiving hole 1111 shown is circular. In practical applications, the receiving hole 1111 can also be rectangular, elliptical, or other shapes for different components located inside different receiving holes 1111. Taking the flash in a camera module as an example, if the outline of the light-emitting surface of the flash is rectangular, then the corresponding receiving hole 1111 can also be designed as rectangular. In addition, depending on the layout structure of the camera, flash, sensor, and other components in the camera module, the receiving holes 1111 on the main board portion 111 of the bracket 110 can be arranged arbitrarily. Taking the outline of the decorative part 100 as circular, a receiving hole 1111 can be provided at the center of the main board portion 111 of the bracket 110, and the remaining receiving holes 1111 can be arranged around the outer periphery of the central receiving hole 1111 and spaced apart along the circumference of the main board portion 111.

[0146] Continue to refer to Figure 8a As shown, the bracket 110 of the decorative piece 100 is also provided with a balancing hole 140, which is used to connect the inside of the electronic device 1 to the outside. Figure 6 and Figure 7 A balance valve 150 is covered on the balance hole 140. The balance valve 150, while ensuring communication between the inside and outside of the electronic device 1, prevents moisture, dust, and other foreign objects from entering the electronic device 1. When the housing 200 of the electronic device 1 is pressed and the air pressure inside the housing of the electronic device 1 increases, air is released through the balance valve 150 to maintain the air pressure balance inside the electronic device 1, avoid polarization of the diaphragm of the audio device 50, and prevent the electronic device 1 from generating noise.

[0147] In the case where the internal components of electronic device 1 are connected to the outside world via balance valve 150, refer to... Figure 7Due to the presence of the assembly gap, there is an unavoidable gap between the periphery of the cover plate 120 and the inner edge of the decorative ring 112. This gap forms the first venting gap a of the decorative part 100. The balance hole 140 can communicate with the first venting gap a. In this way, air can flow inside and outside the electronic device 1 through the first venting gap a and the balance valve 150 to balance the air pressure difference inside and outside the electronic device 1.

[0148] Figure 8b for Figure 5 The diagram shows the bottom view of the support structure for the decorative component. Figure 8b The diagram illustrates the structure of the bracket 110 facing the inner surface of the housing 200, as shown in the reference diagram. Figure 7 and Figure 8b As shown, as an example, since the distance between the second surface of the bracket 110 and the support plate 302 of the middle frame 30 is large, it is convenient to set the first balance valve 151. Therefore, the first balance valve 151 can cover the second surface of the main board part 111, that is, the first balance valve 151 covers the side of the first balance hole 141 facing the inside of the electronic device 1.

[0149] In other examples, if the thickness of the first adhesive layer 130 is sufficient and the gap between the cover plate 120 and the main board portion 111 of the bracket 110 is sufficient to accommodate the first balance valve 151, the first balance valve 151 can also be disposed on the first surface of the bracket 110, that is, the first balance valve 151 covers the side of the first balance hole 141 facing the cover plate 120. Alternatively, if the gap between the cover plate 120 and the main board portion 111 of the bracket 110 is small, a mounting groove (not shown in the figure) can be provided on the main board portion 111. The mounting groove is recessed from the first surface of the main board portion 111 to the second surface, and the mounting groove surrounds the outer periphery of the first balance hole 141. The edge portion of the first balance valve 151 can be attached to the bottom of the mounting groove. The mounting groove can provide installation space for the first balance valve 151 and can also position the first balance valve 151.

[0150] The following description will be based on the example of the first balance valve 151 being attached to the second surface of the main board 111 and the first balance valve 151 covering the side of the first balance hole 141 facing the inside of the electronic device 1.

[0151] In addition, the first balance valve 151 covering the first balance hole 141 can be a waterproof and breathable membrane. The waterproof and breathable membrane can prevent foreign objects such as dust and water vapor from entering the external environment, while allowing air to pass through smoothly, thus serving the functions of waterproofing, dustproofing, and balancing the air pressure inside and outside the electronic device 1. Alternatively, the first balance valve 151 can also be a dustproof net. Since the cover plate 120 of the decorative part 100 already provides good protection, and the first venting gap a between the cover plate 120 and the decorative ring 112 of the bracket 110 is small, it can prevent foreign objects from entering the decorative part 100. In addition, the dustproof net set on the bracket 110 can effectively prevent foreign objects such as dust and water vapor from entering the electronic device 1.

[0152] Figure 9 for Figure 5 A schematic diagram of the decorative element after the cover plate has been removed. Refer to Figure 8 and... Figure 9 As shown, the balance hole 140 opened on the bracket 110 includes a first balance hole 141 located on the main board portion 111. Correspondingly, the balance valve 150 includes a first balance valve 151 covering the first balance hole 141. Furthermore, the first adhesive layer 130 disposed between the main board portion 111 and the cover plate 120 does not completely cover the first surface of the main board portion 111. A venting channel 160 is formed between the area on the first surface of the main board portion 111 that is not covered by the first adhesive layer 130 and the cover plate 120. The venting channel 160 communicates with the edge of the main board portion 111 and communicates with the first venting slot a. The first balance hole 141 communicates with the venting channel 160.

[0153] When the housing 200 of the electronic device 1 is pressed and needs to be vented, the air in the housing of the electronic device 1 flows through the first balance valve 151 covering the first balance hole 141, and then along the venting channel 160 to the first venting slit a around the decorative piece 100, and finally flows outward from the first venting slit a, so as to achieve the purpose of balancing the air pressure inside and outside the electronic device 1. The gas inside the electronic device 1 flows to the outside along the venting path of the decorative piece 100, which will not cause large fluctuations in the air pressure inside the housing of the electronic device 1, and will not affect the diaphragm vibration of the audio device 50, thereby preventing the electronic device 1 from generating noise.

[0154] It should be noted that, in order to ensure the sealing performance of the decorative part 100 on the camera module, the first adhesive layer 130 disposed between the first surface of the main board portion 111 and the cover plate 120 should be ensured to surround the outer periphery of each receiving hole 1111. That is, the first adhesive layer 130 completely surrounds the outer periphery of the receiving hole 1111. The cover plate 120, the first adhesive layer 130, and the main board portion 111 of the bracket 110 together form a sealed space around the outer periphery of the receiving hole 1111 to provide sealed protection for the camera module. When designing the venting channel 160 formed between the main board portion 111 and the cover plate 120, it should be ensured that the first adhesive layer 130 completely surrounds the outer periphery of the receiving hole 1111, and there should be a certain distance between the venting channel 160 and the receiving hole 1111.

[0155] In this embodiment, at least two first balance holes 141 are provided on the main board portion 111 of the bracket 110, and at least two venting channels 160 are formed between the main board portion 111 and the cover plate 120, and the venting channels 160 are interconnected. The first balance hole 141 can be located on the path of any venting channel 160, or the first balance hole 141 can also be located at the intersection of the venting channels 160. After the gas in the containment space of the electronic device 1 enters the venting channel 160 through the first balance valve 151 covered by the first balance hole 141, it can flow from any venting channel 160 to the first venting slit a along the path of the venting channel 160, and be discharged outward from the first venting slit a.

[0156] This avoids the problem of insufficient air release from a single balance valve 150 covering a balance hole 140. By simultaneously releasing air through two or more balance valves 150 covering balance holes 140, the air release requirements of the electronic device 1 can be met. Furthermore, by releasing air through multiple balance valves 150 and multiple air release paths, even if one balance valve 150 is blocked or a part of an air release path 160 is blocked, the gas in the containment space of the electronic device 1 can still be released from the balance valves 150 covering other balance holes 140 and through other air release paths 160, ensuring smooth gas discharge from the containment space and preventing air release failure.

[0157] Continue to refer to Figure 9As shown, taking the receiving hole 1111 provided on the main board part 111 of the bracket 110 as an example, which includes one receiving hole 1111 located at the center of the bracket 110 and four receiving holes 1111 located on the outer periphery of the receiving hole 1111 and arranged circumferentially, the venting channel 160 may include a first channel 160a, a second channel 160b, a third channel 160c and a fourth channel 160d. The four channels all extend from the outer periphery of the receiving hole 1111 located at the center to the edge of the main board part 111. The ends of the four channels near the center of the main board part 111 of the bracket 110 are interconnected. The first channel 160a, the second channel 160b, the third channel 160c and the fourth channel 160d are respectively arranged between two adjacent receiving holes 1111 on the outer periphery. The two first balance holes 141 on the main board part 111 are respectively located on the first channel 160a and the third channel 160c.

[0158] It is understood that in practical applications, the receiving hole 1111 on the bracket 110 can be arranged in other ways, and the venting channel 160 and the first balance hole 141 on the main board part 111 of the bracket 110 can also be designed in other ways. This embodiment does not impose specific restrictions on these.

[0159] In addition, in this embodiment, to effectively ensure the venting capability of the electronic device 1, the multiple first balance holes 141 on the main board portion 111 of the bracket 110 are distributed as dispersed as possible to avoid the first balance valves 151 being too concentrated, which could lead to the risk of all first balance valves 151 being blocked and thus prevent venting failure. Furthermore, if the first balance holes 141 are too concentrated, the venting channels 160 connecting each first balance hole 141 may also be concentrated. If the area of ​​the first venting slot a that corresponds to each venting channel 160 is blocked, it will also lead to venting failure.

[0160] by Figure 9 Taking the example of the bracket 110 motherboard 111 with two first balance holes 141, if the motherboard 111 is divided into two areas with the center line as the dividing line, namely the first area and the second area located on both sides of the center line, then one of the two first balance holes 141 can be located in the first area and the other can be located in the second area, ensuring that the first balance hole 141 is provided in both the first area and the second area, avoiding the first balance hole 141 being concentrated, and avoiding the electronic device 1 from leaking and failing.

[0161] It is understandable that three, four or even more first balance holes 141 can be provided on the main board part 111 of the bracket 110. Similar to providing two first balance holes 141, multiple first balance holes 141 are distributed on the main board part 111 of the bracket 110. First balance holes 141 are provided in both the first region and the second region, which will not be described in detail.

[0162] Furthermore, by distributing multiple first balance holes 141 on the main board 111 of the bracket 110, regardless of which part of the housing 200 the user presses, there is a first balance hole 141 that is close to the pressing part. For the area around the pressing part, the air pressure changes significantly, and the pressure relief flow of the first balance valve 151 that is close to the pressing part is large. In addition, the pressure relief of multiple first balance valves 151 at the same time can quickly relieve the pressure inside the electronic device 1.

[0163] In practical applications, when a user operates an electronic device 1, such as a mobile phone, there are easily pressed areas on the casing 200 of the electronic device 1, especially for decorative parts 100 that protrude from the casing 200, where the user's fingers are likely to press certain areas. In this embodiment, among the multiple first balance holes 141 provided on the main board portion 111 of the bracket 110, a main balance hole (not shown in the figure) may be included. The main balance hole can be located within the easily pressed areas on the bracket 110, and the easily pressed areas of the bracket 110 correspond to the easily pressed areas of the decorative parts 100. The first balance valve 151 covering the main balance hole is defined as the main balance valve (not shown in the figure).

[0164] When the pressable area of ​​the decorative piece 100 is pressed, the air pressure in the space surrounding the pressable area inside the electronic device 1 increases. The pressure inside the electronic device 1 can be quickly released through the main balance valve in this area. Since the pressable area of ​​the decorative piece 100 is a frequently and repeatedly pressed area by the user, by setting the main balance valve in the pressable area, the internal and external pressures of the electronic device 1 can be balanced more quickly and effectively.

[0165] Depending on the layout of the decorative element 100 on the housing 200 and the user's actual operating method, there may be one or more easily pressable areas on the decorative element 100. Correspondingly, the plurality of first balance holes 141 on the main board portion 111 of the bracket 110 may include one or more main balance holes, which is not limited in this embodiment. The area of ​​the main balance hole can be larger than the area of ​​the other balance holes 140. In this way, the area of ​​the main balance valve covering the main balance hole is larger, and the degassing efficiency of the main balance valve is faster, which helps to quickly release the pressure inside the electronic device 1.

[0166] Figure 10 for Figure 5 A schematic diagram showing the orientation of the decorative elements on the middle frame after the cover plate has been removed; Figure 11 for Figure 7 A magnified view of a portion at point A in the middle. Figure 10The venting channel 160 shown includes a first channel 160a extending toward the top of the electronic device 1. The first channel 160a communicates with the area at the top of the corresponding decorative piece 100 of the first venting slit a, and a first balancing hole 141 is provided on the first channel 160a. Figure 11 The dashed arrow in the example illustrates one possible venting path. (Refer to...) Figure 11 As shown, the gas in the containment space of the electronic device 1 passes through the first balance valve 151 and the first balance hole 141, and then enters the first channel 160a. The gas flows along the first channel 160a to the first venting slot a, and then flows to the outside through the first venting slot a.

[0167] In addition, combined Figure 7 and Figure 11 As shown, when the overlapping edge 114 of the bracket 110 is connected to the inner surface of the housing 200, and the side wall 113 of the bracket 110 extends outward through the mounting hole 210 on the housing 200, a second venting gap b is formed between the outer wall surface of the side wall 113 of the bracket 110 and the hole wall of the mounting hole 210 of the housing 200 due to the assembly gap. In order to ensure the venting effect of the electronic device 1, in addition to venting outward through the first venting gap a, the electronic device 1 of this embodiment can also vent outward through the second venting gap b to reduce the risk of venting failure caused by partial blockage of the first venting gap a.

[0168] The outer wall surface of the side wall 113 of the bracket 110 refers to the side wall surface of the side wall 113 facing the hole wall of the mounting hole 210 of the housing 200. In contrast, the inner wall surface of the side wall 113 of the bracket 110 refers to the side wall surface of the side wall 113 facing the center of the bracket 110.

[0169] Combination Figure 9 and Figure 11 As shown, in order to allow the electronic device 1 to vent air outward from the second venting seam b, a venting groove 1131 and a connecting groove 1132 are also provided on the side wall 113 of the bracket 110 of the decorative part 100. The opening of the venting groove 1131 is located on the first surface of the main board portion 111, and the opening of the venting groove 1131 communicates with the venting channel 160. For example, the opening of the venting groove 1131 can be located on the path of the venting channel 160. The venting groove 1131 extends along the extending direction of the side wall 113, and the bottom of the venting groove 1131 extends towards the end of the side wall 113 that connects with the overlapping edge 114, so that the bottom of the venting groove 1131 can extend to the area corresponding to the plane of the housing 200. The connecting groove 1132 can be set to correspond to the wall of the mounting hole 210. The opening of the connecting groove 1132 is located on the outer wall surface of the side wall 113 of the bracket 110, and the connecting groove 1132 extends to the inner wall surface of the side wall 113 to communicate with the air guide groove 1131.

[0170] Reference Figure 11 As shown, the air in the containment space of the electronic device 1 passes through the first balance valve 151 and the first balance hole 141, and then enters the first channel 160a. The gas flows along the first channel 160a to the opening of the air guide groove 1131, and then flows through the air guide groove 1131 and the connecting groove 1132 to the second venting slot b, and finally flows to the outside through the second venting slot b.

[0171] It should be noted that, Figure 11 Only the middle part is shown Figure 10 The air venting path is located near the top of the middle frame 30. An air guide groove 1131 is provided on the side wall 113 of the bracket 110 near the top of the middle frame 30. Therefore, in the area of ​​the decorative piece 100 near the top of the middle frame 30, the decorative piece 100 can not only vent outwards from the first air vent a, but also vent outwards from the second air vent b via the air guide groove 1131. Figure 9 As shown, multiple air guide grooves 1131 can be provided on the side wall 113 of the bracket 110. The multiple air guide grooves 1131 are arranged at intervals along the circumference of the side wall 113 of the bracket 110. Taking four air guide grooves 1131 evenly spaced along the circumference on the side wall 113 as an example, each air guide groove 1131 is connected to the venting channel 160. Thus, when venting, the gas in the electronic device 1 can also be vented outward from the second venting seam b through any air guide groove 1131 on the side wall 113 of the bracket 110. The number of venting paths increases, which reduces the risk of venting failure caused by the blockage of one or more venting paths while ensuring the amount of venting.

[0172] In practical applications, the sidewall 113 of the bracket 110 of the decorative component 100 is usually thinner to reduce the overall thickness of the bracket 110 and achieve a thinner and lighter decorative component 100. Figure 8b and Figure 11 As shown, in this embodiment, when the thickness of the side wall 113 of the bracket 110 is insufficient to accommodate the air guide groove 1131, an inner extension 1133 is added to the side wall 113 of the bracket 110. The inner extension 1133 protrudes from the inner wall of the side wall 113 towards the center of the bracket 110. The thickness of the side wall 113 of the bracket 110 is increased by the inner extension 1133, thus allowing the air guide groove 1131 to be formed on the inner extension 1133. Simultaneously, the inner extension 1133 does not affect the shape and dimensions of the outer wall surface of the side wall 113, has no impact on the overall size of the bracket 110, and does not affect the assembly of the bracket 110 with the housing 200.

[0173] In the case where multiple air guide grooves 1131 are provided circumferentially at intervals on the side wall 113 of the support 110, refer to Figure 8bAs shown, multiple inner extensions 1133 can be spaced circumferentially on the sidewall 113, and each inner extension 1133 has an air guide groove 1131. For example, each inner extension 1133 can have one air guide groove 1131, or each inner extension 1133 can have two or more air guide grooves 1131 spaced apart. Provided that the area of ​​the main board portion 111 of the bracket 110 is sufficient and does not affect the setting of the receiving hole 1111, the inner extension 1133 can also surround the entire circumference of the sidewall 113, which is equivalent to increasing the overall thickness of the sidewall 113 of the bracket 110. In this case, the air guide groove 1131 can be opened at any part of the sidewall 113 of the bracket 110 according to the design requirements.

[0174] Figure 12a This is a schematic diagram of one arrangement of the first adhesive layer on the bracket provided in an embodiment of this application; Figure 12b This is a schematic diagram illustrating another arrangement of the first adhesive layer on the support, as provided in an embodiment of this application. Figure 12c This is a schematic diagram of a third arrangement of the first adhesive layer on the support, as provided in an embodiment of this application.

[0175] Regarding the specific layout of the first adhesive layer 130 bonded to the first surface of the main board portion 111 of the bracket 110 and the structural form of the venting channel 160 formed therefrom, please refer to... Figure 12a As shown, in one embodiment, the first adhesive layer 130 bonded to the first surface of the main board portion 111 may include two or more adhesive sheets 131, which are spaced apart from each other. The edges of the adhesive sheets 131 extend to the edges of the main board portion 111, and the gaps between adjacent adhesive sheets 131 form a venting channel 160 between the main board portion 111 and the cover plate 120. In this embodiment, the venting channel 160 formed in this manner is defined as the first venting channel 161. The first venting channel 161 located between adjacent adhesive sheets 131 extends from the middle of the main board portion 111 to the edge, and the end of the first venting channel 161 corresponds to a local area of ​​the first venting seam a.

[0176] Multiple first venting channels 161 extending from the center to the edge of the main board portion 111 can intersect and connect with each other in their respective end regions near the center of the main board portion 111, or they can intersect with other first venting channels 161 in the middle section of their respective extension directions. In this case, the first balance hole 141 on the main board portion 111 can be provided in the middle region of the extension direction of the first venting channels 161.

[0177] by Figure 12aTaking the layout of the bracket 110 in the example as an example, the first adhesive layer 130 may include five films 131, which are arranged one-to-one around the five receiving holes 1111, and are separated from each other. Thus, the four films 131 on the outer periphery form four first venting channels 161 in pairs. The four first venting channels 161 intersect on the periphery of the film 131 located in the center, and all four channels extend to the edge of the main board portion 111. The dotted lines in the figure illustrate the venting path. After passing through the first balance valve 151, the gas inside the electronic device 1 can flow freely along the interconnected first venting channels 161 and be discharged outwards from the first venting slit a and the second venting slit b.

[0178] Reference Figure 12b As shown, in another embodiment, the first adhesive layer 130 bonded between the first surface of the main board portion 111 and the cover plate 120 can also be a single integral film 131. The middle region of the film 131 can be opened corresponding to each receiving hole 1111, so that the film 131 surrounds the outer periphery of all receiving holes 1111. Furthermore, the edge of the film 131 forms a recessed section 1311, which is located between adjacent first balance holes 141, and there is a gap between the recessed section 1311 and the edge of the main board portion 111. The gap between the recessed section 1311 and the decorative ring 112 forms a venting channel 160. In this embodiment, the venting channel 160 formed in this way is defined as a second venting channel 162. The second venting channel 162, located between the recessed section 1311 on the outer edge of the film 131 and the decorative ring 112, extends along the periphery of the main board portion 111, and the second venting channel 162 is directly opposite the first venting seam a.

[0179] The first balancing hole 141 can be connected to the end of the second venting channel 162 extending along the periphery of the main board portion 111. The two ends of the second venting channel 162 are respectively connected to two adjacent second balancing holes 142. The second venting channels 162 located on both sides of the second balancing hole 142 are interconnected through the second balancing hole 142.

[0180] by Figure 12bTaking the layout of the bracket 110 as an example, the integral first adhesive layer 130 surrounds the five receiving holes 1111 on the main board portion 111 of the bracket 110. The portions of the first adhesive layer 130 corresponding to the two first balance holes 141 on both sides open towards the edge of the main board portion 111. The edge of the adhesive layer 131 forms a notch 1311 on both sides of the two first balance holes 141. The notch 1311 is spaced from the edge of the main board portion 111, and the notches 1311 on both sides extend to the opening of the corresponding first balance hole 141. The dotted line in the figure indicates the venting path. After the gas in the electronic device 1 passes through the first balance valve 151, it can flow freely along the interconnected second venting channel 162 and be discharged outward from the first venting slit a and the second venting slit b.

[0181] Reference Figure 12c As shown, as a third implementation method, it incorporates... Figure 12a and Figure 12b The structure includes a first adhesive layer 130 bonded between the main board portion 111 and the cover plate 120, which may include two or more adhesive sheets 131. Each adhesive sheet 131 is separated from the others, and the edge of the adhesive sheet 131 near the edge of the main board portion 111 of the bracket 110 forms a notch 1311. There is a gap between the notch 1311 and the edge of the main board portion 111 of the bracket 110. A first venting channel 161 is formed between two adjacent adhesive sheets 131. Each first venting channel 161 intersects with the others. A second venting channel 162 is formed between the notch 1311 on the edge of the adhesive sheet 131 and the decorative ring 112. The second venting channel 162 is connected to the first venting channel 161.

[0182] by Figure 12c Taking the bracket 110 layout as an example, the first adhesive layer 130 may include five films 131 corresponding to the five receiving holes 1111, with each film 131 separated from the others. Thus, the four films 131 on the outer periphery form four first venting channels 161 in pairs. The four first venting channels 161 intersect on the periphery of the central film 131, and all four channels extend to the edge of the main board portion 111. Furthermore, a second venting channel 162 is formed between the recessed section 1311 on the outer edge of the four films 131 and the decorative ring 112, and the second venting channel 162 communicates with the ends of each of the first venting channels 161. The dashed lines in the figure illustrate the venting path. After passing through the first balance valve 151, the gas inside the electronic device 1 can flow freely along the interconnected first venting channels 161 and second venting channels 162, and is discharged outward from the first venting slit a and the second venting slit b.

[0183] Figure 13 for Figure 11 Another partial structural diagram of the decorative element. Combined with... Figure 10 and Figure 13 As shown, based on the first venting slot a formed between the cover plate 120 and the decorative ring 112 of the decorative part 100, a stepped groove 1121 can be formed on the decorative ring 112 to increase the venting area. The stepped groove 1121 corresponds to the end of the venting channel 160. The stepped groove 1121 extends from the inner wall surface of the decorative ring 112 to the outer wall surface, and the stepped groove 1121 connects to the top surface of the decorative ring 112. By setting the stepped groove 1121, the gap between the bottom of the stepped groove 1121 and the periphery of the cover plate 120 is increased, which increases the width of the local area of ​​the first venting slot a corresponding to the venting channel 160, thereby increasing the venting area of ​​the first venting slot a and accelerating the venting efficiency of the electronic device 1.

[0184] It should be noted that the solution of setting a stepped groove 1121 on the decorative ring 112 is mainly for the venting channel 160 formed between the bracket 110 and the cover plate 120, which is the aforementioned first venting channel 161. The end of the first venting channel 161 corresponds to a local area of ​​the decorative ring 112. A stepped groove 1121 can be set in the corresponding area of ​​the decorative ring 112 to increase the venting area of ​​the first venting seam a at the end of the first venting channel 161. As for the structure in which a second venting channel 162 is formed between the bracket 110 and the cover plate 120, since the second venting channel 162 surrounds the edge of the main plate 111, it is directly opposite the first venting seam a and covers a wide area, resulting in a larger venting area. Furthermore, since the second venting channel 162 surrounds the edge of the main plate 111, the area corresponding to the decorative ring 112 is large, making it inconvenient to position the stepped groove 1121.

[0185] In cases where multiple first venting channels 161 correspond to multiple local areas on the decorative ring 112, only one stepped groove 1121 can be provided on the decorative ring 112, which corresponds to the end of one of the first venting channels 161; or, multiple stepped grooves 1121 can be provided circumferentially on the decorative ring 112, with each stepped groove 1121 corresponding to the end of one of the first venting channels 161.

[0186] Continue to refer to Figure 13 As shown, similar to increasing the venting area of ​​the first venting slot a by setting a stepped groove 1121 on the decorative ring 112, the volume of the connecting slot 1132 opened on the side wall 113 of the bracket 110 can also be increased, so that the top wall of the connecting slot 1132 (the inner wall of the connecting slot 1132 on the side near the first surface of the main board portion 111) is higher than the plane where the outer surface of the housing 200 is located, that is, the top area of ​​the connecting slot 1132 is exposed outside the housing 200. In this way, it is equivalent to increasing the width of the second venting slot b at the location of the connecting slot 1132, increasing the venting area of ​​the second venting slot b, and improving the venting efficiency of the electronic device 1.

[0187] Alternatively, similar to the stepped groove 1121 on the decorative ring 112, a notch can be provided on the wall of the mounting hole 210 of the housing 200. The notch corresponds to the connecting groove 1132 and is recessed in a direction away from the decorative part 100. The width of the second venting slot b at the location of the connecting groove 1132 is increased by the notch.

[0188] Example 2

[0189] Figure 14 This is a schematic diagram of the structure of another decorative component provided in an embodiment of this application; Figure 15 for Figure 14 A schematic diagram showing the orientation of the decorative elements on the middle frame after the cover plate has been removed; Figure 16 For installation Figure 14 decorative parts Figure 1 A schematic cross-sectional view of the BB of the electronic device in the diagram; Figure 17 for Figure 16 A magnified view of a section at point B in the middle; Figure 18a for Figure 14 A layout diagram of the decorative elements (after removing the cover plate); Figure 18b for Figure 14 Another layout diagram of the decorative elements (after removing the cover plate); Figure 18c for Figure 14 The third layout structure diagram of the decorative parts (after removing the cover plate); Figure 18d for Figure 14 The fourth layout structure diagram of the decorative parts (after removing the cover plate).

[0190] Reference Figure 14 As shown, based on the decorative part 100 provided in Embodiment 1, this embodiment modifies the structure of the bracket 110. This embodiment mainly focuses on the structural form where the overlapping edge 114 of the bracket 110 connects to the inner surface of the electronic device 1 housing 200. The side wall 113 of the bracket 110 extends outward from the mounting hole 210 of the housing 200 to the electronic device 1. By improving the structure of the overlapping edge 114 of the bracket 110, more balance holes 140 and balance valves 150 are added, increasing the number of venting paths. Apart from the structural change of the overlapping edge 114 of the bracket 110, the other layout structures of the decorative part 100 are similar to those in Embodiment 1, and will not be described again here.

[0191] In this embodiment, the overlapping edge 114 of the decorative component 100 bracket 110 has an extension portion 1141. The extension portion 1141 extends outward from the bracket 110, increasing the width of the overlapping edge 114. A balance hole 140 can be added to the extension portion 1141. In this embodiment, the balance hole 140 provided on the extension portion 1141 is defined as a second balance hole 142, and the balance valve 150 covering the second balance hole 142 is defined as the second balance valve 152. Furthermore, with... Figure 15 When the bracket 110 shown is assembled onto the electronic device 1, the extension portion 1141 is configured to correspond to the width direction of the electronic device 1, for example. Figure 16 and Figure 17 As shown, the inner surface of the housing 200, the extension portion 1141, and the second adhesive layer 180 bonded between the housing 200 and the extension portion 1141 together form an air guide channel 170. The air guide channel 170 extends to the side wall 113 of the bracket 110 and communicates with the venting channel 160 formed between the main plate portion 111 and the cover plate 120 of the bracket 110. The second balance hole 142 is located in the air guide channel 170.

[0192] Among them, reference Figure 15 As shown, the second adhesive layer 180, which is bonded to the overlapping edge 114 of the bracket 110, can be disposed as close as possible to the outer edge of the overlapping edge 114. The second adhesive layer 180 extends along the outer edge of the extension portion 1141 in the area where the extension portion 1141 is located. In this way, most of the area of ​​the extension portion 1141 is located within the air guide channel 170 formed by the extension portion 1141, the housing 200, and the second adhesive layer 180, which can ensure that the second balance hole 142 opened on the extension portion 1141 is located within the air guide channel 170.

[0193] Reference Figure 17 As shown, when venting is required, the gas in the containment space of the electronic device 1 can also enter the venting channel 170 through the second balance valve 152 covered by the second balance hole 142 on the extension portion 1141, flow through the venting channel 170 to the second venting slit b formed between the side wall 113 of the bracket 110 and the wall of the mounting hole 210 of the housing 200, and flow out from the second venting slit b. Alternatively, the gas entering the venting channel 170 can also flow through the connecting groove 1132 and the venting groove 1131 opened on the side wall 113 to the first venting slit a formed between the decorative ring 112 of the bracket 110 and the cover plate 120, and flow out from the first venting slit a.

[0194] Since the air guide channel 170 connects to the side wall 113 of the bracket 110, a second venting slit b is formed between the side wall 113 of the bracket 110 and the wall of the mounting hole 210 of the housing 200. Therefore, the gas entering the air guide channel 170 can flow out through the second venting slit b. At the same time, since the air guide channel 170 and the venting channel 160 formed between the main board portion 111 of the bracket 110 and the cover plate 120 are connected, the gas in the air guide channel 170 can also flow to any interconnected venting channel 160 and be vented out through the first venting slit a.

[0195] Thus, based on the venting of the first balance valve 151, by adding a second balance hole 142 to the extension portion 1141, the venting of the second balance valve 152 is increased. If the first balance valve 151 is blocked, the second balance valve 152 can still ensure effective venting of the electronic device 1. The air guide channel 170 connecting the second balance valve 152 extends to the side wall 113 of the bracket 110, ensuring that the second balance valve 152 can vent outward through the second venting slot b. Based on this, referring to... Figures 18a-18c The dashed lines indicate the venting paths. By connecting the venting channel 170 with all venting channels 160, the second balancing valve 152 can also vent externally through any venting channel 160 via the first venting slot a. Electronic device 1 vents externally through the first balancing valve 151 and the second balancing valve 152 via multiple venting paths, reducing the risk of venting failure due to blockage of local venting paths.

[0196] Reference Figures 18a-18c As shown, in some embodiments, the second balance hole 142 on the extension portion 1141 can correspond to the air guide groove 1131 on the side wall 113 of the bracket 110. The air guide channel 170 communicating with the second balance hole 142 is directly connected to the air guide groove 1131. The air guide groove 1131 is connected to the venting channel 160 formed between the main board portion 111 and the cover plate 120 of the bracket 110. At this time, the gas in the electronic device 1 passes through the second balance valve 152, enters the air guide groove 1131 directly through the air guide channel 170, and then enters the venting channel 160.

[0197] In a layout similar to that of the first adhesive layer 130 on the main board portion 111 of the bracket 110 in Embodiment 1, by structurally designing the first adhesive layer 130, the venting channel 160 formed between the main board portion 111 and the cover plate 120 can simultaneously include a first venting channel 161 and a second venting channel 162. Figure 18a Alternatively, the venting channel 160 formed between the main board 111 and the cover plate 120 may only include the first venting channel 161. Figure 18b Alternatively, the venting channel 160 formed between the main board 111 and the cover plate 120 may only include the second venting channel 162. Figure 18c ).

[0198] Reference Figure 18d As shown, in some other embodiments, in the circumferential direction of the bracket 110, the second balance hole 142 on the extension portion 1141 can be offset from the air guide groove 1131 on the side wall 113 of the bracket 110, and the air guide channel 170 formed between the extension portion 1141 and the housing 200 is also offset from the air guide groove 1131. Since the air guide channels 170 corresponding to each second balance hole 142 are in a ring-shaped interconnected state around the side wall 113, at this time, the gas in the electronic device 1 passes through the second balance valve 152 and flows in the ring-shaped air guide channel 170 around the side wall 113 of the bracket 110 until it flows to the corresponding air guide groove 1131 on the side wall 113, and then enters the venting channel 160 from the air guide groove 1131.

[0199] Understandably, although Figure 18d The layout of the first adhesive layer 130 shown defines a venting channel 160 formed between the main board portion 111 and the cover plate 120, which includes both a first venting channel 161 and a second venting channel 162. However, by designing the first adhesive layer 130, it can be combined with... Figure 18b and Figure 18c Similarly, provided that the second balance hole 142 on the extension portion 1141 and the air guide groove 1131 on the side wall 113 of the bracket 110 are staggered, the venting channel 160 formed between the main plate portion 111 and the cover plate 120 may only include the first venting channel 161 or the second venting channel 162.

[0200] Furthermore, to allow the electronic device 1 to vent air through more balance valves 150, two or more second balance holes 142 can be provided on the extended portion 1141. Air is vented through the second balance valves 152 covered by each second balance hole 142. Combined with the multiple first balance valves 151 on the main board portion 111 of the bracket 110, the number of balance valves 150 is increased, and the area covered by the balance valves 150 is expanded, thereby increasing the venting area and venting efficiency of the electronic device 1. At the same time, venting air through multiple balance valves 150 and multiple venting paths can prevent venting failure.

[0201] Continue to refer to Figures 18a-18dAs shown, in one embodiment, two or more extension portions 1141 can be provided at intervals along the circumference of the overlap edge 114. The figure illustrates two extension portions 1141 as an example; however, it is understood that three or more extension portions 1141 can also be provided at intervals along the circumference of the overlap edge 114. A second balancing hole 142 is provided on each extension portion 1141. For example, one second balancing hole 142 is provided on each extension portion 1141, or two or more second balancing holes 142 are provided at intervals on each extension portion 1141. The air guiding channels 170 formed by the extension portions 1141 are interconnected, and the air guiding channels 170 are connected to the venting channels 160.

[0202] Figure 19 This is a front view of the third decorative element provided in this application embodiment after the cover plate has been removed. (Refer to...) Figure 19 As shown, in another embodiment, if there is sufficient bonding area on the inner wall surface of the housing 200, the width of the overlap edge 114 of the bracket 110 can be widened as a whole. That is, the extension portion 1141 can be set as an annular portion, and two or more second balance holes 142 are opened circumferentially on the annular extension portion 1141 (two second balance holes 142 are used as an example in the figure). The dotted line in the figure shows the venting path, wherein the annular extension portion 1141 forms an annular venting channel 170, which is connected to the venting channel 160. After the gas in the electronic device 1 passes through the second balance valve 152, it can be vented outward through the venting channel 170 from the second venting slit b, or it can be vented outward through any venting channel 160 from the first venting slit a.

[0203] Furthermore, regardless of whether multiple extension portions 1141 are spaced apart circumferentially along the overlap edge 114, or the overlap edge 114 is widened to form an annular extension portion 1141, among the multiple second balance holes 142 provided on the extension portion 1141, all the second balance holes 142 may correspond to the corresponding air guide grooves 1131 on the side wall 113 of the bracket 110, or all the second balance holes 142 may be staggered from the air guide grooves 1131, or some of the second balance holes 142 may correspond to the corresponding air guide grooves 1131 and some of the second balance holes 142 may be staggered from the air guide grooves 1131. This embodiment does not impose specific limitations on this.

[0204] It is understood that, similar to the first balance valve 151 covering the first balance hole 141, the second balance valve 152 covering the second balance hole 142 can be provided on the side surface of the extension portion 1141 facing the inside of the electronic device 1 (facing the support plate 302 of the middle frame 30), or the second balance valve 152 can also be provided on the side surface of the extension portion 1141 facing the outside of the electronic device 1 (facing the housing 200). Furthermore, the second balance valve 152 can also be a waterproof and breathable membrane or a dustproof mesh.

[0205] Additionally, similar to Embodiment 1, when the easily pressable area on the housing 200 corresponds to the area where the extension 1141 of the overlapping edge 114 of the bracket 110 is located, the second balancing hole 142 on the extension 1141 can also be set as the main balancing hole. In the case of multiple second balancing holes 142, one or more main balancing holes may be among the second balancing holes 142. The area of ​​the main balancing hole can be larger than the area of ​​the other balancing holes 140, which will not be elaborated further here.

[0206] Example 3

[0207] Based on Embodiment 1 and Embodiment 2, this embodiment changes the venting structure of the decorative part 100, which will be described in detail below.

[0208] Figure 20 A partial cross-sectional view of the fourth decorative element provided in an embodiment of this application. (Refer to...) Figure 20 As shown, based on the air guide groove 1131 opened on the side wall 113 of the bracket 110 of the decorative part 100, in addition to the aforementioned opening of the connecting groove 1132 extending from the outer wall surface to the inner wall surface on the side wall 113, by making the connecting groove 1132 correspond to the second air vent b and communicate with the air guide groove 1131, so that air can be vented outward through the second air vent b, as an alternative, in this embodiment, a first air vent hole 1134 can be opened on the side wall 113 of the bracket 110, and air can be vented outward through the first air vent hole 1134.

[0209] The first vent 1134 extends from the outer wall of the side wall 113 to the inner wall, communicating with the vent groove 1131, and is exposed outside the housing 200 of the electronic device 1. Thus, gas inside the electronic device 1 flows through the venting channel 160 to the vent groove 1131, then enters the first vent 1134 from the vent groove 1131, and can flow directly to the outside through the first vent 1134 without needing to vent through the second venting slit b.

[0210] Figure 21 A partial cross-sectional view of the fifth decorative element provided in an embodiment of this application. (Refer to...) Figure 21 As shown, in other embodiments, a second vent hole 121 may be provided on the cover plate 120. The second vent hole 121 is disposed away from the first adhesive layer 130, so that the second vent hole 121 is located within the coverage area of ​​the venting channel 160 formed between the main board portion 111 of the bracket 110 and the cover plate 120. In this way, the second vent hole 121 communicates with the venting channel 160, and the gas in the electronic device 1 flows along the venting channel 160 after passing through the first balance valve 151, and is discharged from the second vent hole 121.

[0211] The second vent 121 is covered with a decorative mesh 122. The decorative mesh 122 has a porous structure. On the one hand, the decorative mesh 122 serves to allow air to pass through and prevent foreign objects such as dust and water droplets from entering the electronic device 1. On the other hand, by selecting and designing the material and shape of the decorative mesh 122, it can also achieve an aesthetic effect.

[0212] Depending on actual needs, one or more second vent holes 121 can be provided on the cover plate 120. It should be noted that while providing the second vent hole 121 on the cover plate 120, a guide groove 1131 can also be provided on the side wall 113 of the bracket 110, and a connecting groove 1132 or a first vent hole 1134 communicating with the guide groove 1131 can be provided to allow air to vent outward simultaneously through the second vent slot b or the first vent hole 1134.

[0213] In addition, the projection of the second vent hole 121 on the cover plate 120 onto the main board 111 can be located within the coverage area of ​​the first balance hole 141. Thus, the second vent hole 121 is directly opposite the first balance valve 151, and the venting path between them is short. After the gas in the electronic device 1 passes through the first balance valve 151, it can be directly vented out through the decorative mesh 122 covering the second vent hole 121, resulting in high venting efficiency.

[0214] Continue to refer to Figure 21 As shown, the decorative mesh 122 covering the second vent hole 121 may include an inner portion 1221 and an outer ring portion 1222. The outer ring portion 1222 surrounds the outer periphery of the inner portion 1221, and the decorative mesh 122 can be an integral structural component. The inner portion 1221 protrudes from the side of the outer ring portion 1222 facing the cover plate 120, and the outer ring portion 1222 is fitted and connected to the inner surface of the cover plate 120 to connect and fix the decorative mesh 122 to the cover plate 120. The inner portion 1221 is embedded in the second vent hole 121 to cover the second vent hole 121. In this way, connecting the decorative mesh 122 to the inner surface of the cover plate 120 can ensure that the decorative mesh 122 is firmly connected and does not affect the flatness of the outer surface of the cover plate 120. The inner portion 1221 is exposed in the second vent hole 121, which can achieve a decorative effect.

[0215] For example, the top surface of the embedded portion 1221, that is, the side surface of the embedded portion 1221 facing away from the outer ring portion 1222, can be flush with the outer surface of the cover plate 120. In this way, the embedded portion 1221 can be clearly exposed in the second vent hole 121, which has a better decorative effect; and the embedded portion 1221 does not affect the flatness of the outer surface of the cover plate 120. At the same time, the top surface of the embedded portion 1221 is flush with the outer surface of the cover plate 120, which can prevent dust, dirt and other foreign objects from accumulating on the decorative mesh 122.

[0216] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0217] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
