Description

Technical Field

[0001] The present application belongs to the technical field of communication equipment, and specifically relates to an electronic device. Background Art

[0002] With the advancement of technology, electronic devices (such as mobile phones and tablet computers) have made great progress. As a powerful tool, electronic devices have greatly facilitated the lives and work of users.

[0003] In the related art, in order to prevent water vapor and dust in the external environment from entering the electronic equipment, the electronic equipment usually has good sealing performance, thereby meeting the waterproof and dustproof requirements of the electronic equipment.

[0004] However, the better the sealing performance of an electronic device, the greater the change in its internal air pressure when the electronic device is impacted. For example, when the housing of an electronic device is subjected to external pressure, the internal air pressure of the electronic device is likely to increase sharply due to the good sealing performance of the electronic device, which in turn easily causes the pressure of the internal components of the electronic device to be too high, thus affecting the normal use of the internal components of the electronic device. For example, when the internal air pressure of an electronic device increases sharply, the diaphragm of the earpiece of the electronic device is likely to be squeezed, causing the earpiece to produce a large noise. Therefore, the reliability of the electronic devices in the related art is poor. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem of poor reliability of the electronic device.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0007] The embodiment of the present application provides an electronic device, including a device housing, an optical module and a decorative element;

[0008] The device housing is provided with a through hole, at least part of the optical module is arranged inside the device housing, the decorative element is sealed and connected to the device housing, the decorative element is provided with a light-transmitting area, and the optical module is arranged opposite to the light-transmitting area and the through hole;

[0009] The decorative component is provided with an external air pressure balance hole, an internal air pressure balance hole and an air pressure balance channel. The air pressure balance channel is connected with the external environment of the electronic device through the external air pressure balance hole; the air pressure balance channel is connected with the inner cavity of the device shell through the internal air pressure balance hole; the air pressure balance channel extends along the circumference of the decorative component.

[0010] In the embodiment of the present application, the decorative part is provided with an external air pressure balance hole, an internal air pressure balance hole and an air pressure balance channel, and the air pressure balance channel is connected to the external environment of the electronic device through the external air pressure balance hole. The air pressure balance channel is connected to the inner cavity of the device housing through the internal air pressure balance hole. In this scheme, the external air pressure balance hole, the internal air pressure balance hole and the air pressure balance channel provided by the decorative part can achieve a relative balance of the internal and external air pressure of the electronic device, thereby avoiding a sharp increase in the internal air pressure of the electronic device, so that the internal and external pressures of the electronic device are relatively balanced, so it is not easy to affect the normal use of the internal components of the electronic device, thereby improving the reliability of the electronic device. In addition, in the electronic device disclosed in the present application, the air pressure balance channel extends toward the circumference of the decorative part. At this time, the ventilation structure formed by the external air pressure balance hole, the internal air pressure balance hole and the air pressure balance channel is long and has a complex structure, so the ventilation structure has a good waterproof and dustproof effect, so the electronic device disclosed in the present application can not only avoid the risk of a sharp increase in the internal air pressure of the electronic device, but also make the electronic device have a good waterproof and dustproof performance.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0025] In the related art, in order to balance the internal and external air pressure of the electronic device, a vent hole is opened on the shell of the electronic device, and the vent hole is covered with a waterproof breathable membrane, which is used to achieve the functions of dustproof, waterproof and breathable. However, due to the high cost of the waterproof breathable membrane, the manufacturing cost of the electronic device in the related art is high. In addition, the waterproof breathable membrane occupies a large space of the electronic device, which is not conducive to the development of thin and light electronic equipment. In addition, although the waterproof breathable membrane can prevent dust and water vapor from entering the interior of the electronic device, over time, dust will accumulate on the membrane, and in severe cases, it will block the vent hole, thereby affecting the internal and external air pressure of the electronic device. Therefore, the reliability of the electronic device in the related art is poor.

[0026] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0027] Please refer to Figures 1 to 13 An embodiment of the present application discloses an electronic device, and the disclosed electronic device includes a device housing 100, an optical module 200 and a decorative component 300.

[0028] The device housing 100 provides installation space for other components of the electronic device, and at least part of the optical module 200 is disposed inside the device housing 100. The optical module 200 may be an optical device such as a fill light, a camera module, an optical fingerprint module, an optical sensor, etc.

[0029] The device housing 100 is provided with a through hole 101, where the through hole 101 is arranged opposite to the optical module 200, so the through hole 101 is used for the optical module 200 to transmit light. In addition, the through hole 101 can also be used to install the decorative piece 300. The decorative piece 300 is sealed and connected to the device housing 100. Specifically, the decorative piece 300 and the device housing 100 can be bonded by the second bonding portion 340, where the second bonding portion 340 can be a bonding structure such as double-sided tape, glue, etc. Of course, other bonding structures can also be used, which is not limited herein. The decorative piece 300 is used to cover part of the optical module 200, so as to prevent the user from seeing the unnecessary part of the optical module 200, thereby improving the appearance texture of the electronic device and improving the user experience. For example, the decorative piece 300 covers the gap between the device housing 100 and the optical module 200, as well as the outer shell and other components of the optical module 200. The decorative piece 300 is provided with a light-transmitting area, and the optical module 200 is arranged opposite to the light-transmitting area and the through hole 101. The optical module 200 is disposed opposite to the light-transmitting area, so that it can work through the light-transmitting area.

[0030] The light-transmitting area here can be a light-transmitting hole, in which case the decorative element 300 is an annular structure as a whole, that is, the decorative element 300 is arranged around the optical module 200. Alternatively, the light-transmitting area can be a solid structure that can transmit light, in which case the decorative element 300 can cover the through hole 101 as a whole, and the decorative element 300 is provided with a light-transmitting area made of transparent glass, transparent resin or other materials.

[0031] In the present application, the decorative member 300 is provided with an external air pressure balance hole 301, an internal air pressure balance hole 302 and an air pressure balance channel 303, and the air pressure balance channel 303 is connected to the external environment of the electronic device through the external air pressure balance hole 301. The air pressure balance channel 303 is connected to the inner cavity of the device housing 100 through the internal air pressure balance hole 302. The air pressure balance channel 303 extends toward the circumference of the decorative member 300. At this time, the external air pressure balance hole 301 and the internal air pressure balance hole 302 can be spaced apart along the extension direction of the air pressure balance channel 303, that is, the external air pressure balance hole 301 and the internal air pressure balance hole 302 are relatively far apart. Optionally, the external air pressure balance hole 301 and the internal air pressure balance hole 302 can be located at both ends of the air pressure balance channel 303, or in an area close to both ends of the air pressure balance channel 303.

[0032] In the embodiment of the present application, the external air pressure balance hole 301, the internal air pressure balance hole 302 and the air pressure balance channel 303 form an air pressure channel, which connects the internal and external environmental air pressures of the electronic device, thereby making the internal and external air pressures of the electronic device relatively balanced, thereby avoiding a sharp increase in the internal air pressure of the electronic device, thereby making the internal and external pressures of the electronic device more balanced, and therefore not easily affecting the normal use of the internal components of the electronic device, thereby improving the reliability of the electronic device.

[0033] In the present application, the air pressure balance channel 303 extends toward the circumference of the decorative element 300. At this time, the ventilation structure formed by the external air pressure balance hole 301, the internal air pressure balance hole 302 and the air pressure balance channel 303 is relatively long and has a complex structure. Therefore, water vapor and dust in the external environment are more likely to settle in the ventilation structure, so the ventilation structure has a good waterproof and dustproof effect. The electronic device disclosed in the present application can not only avoid the risk of a sharp increase in the internal air pressure of the electronic device, but also make the electronic device have good waterproof and dustproof performance.

[0034] Compared with the solutions in the related art, the electronic device in the present application adopts the method of setting an air pressure balance structure on the decorative part 300 to achieve waterproof, dustproof and ventilation. Therefore, the cost of the electronic device in the present application is lower than the cost of the electronic device with a waterproof and breathable membrane in the related art. In addition, the present application sets an air pressure balance structure on the decorative part 300 of the optical module 200, so it does not occupy the installation space of the electronic device, which is more conducive to the development of thin and light electronic equipment. In addition, the air pressure balance structure disclosed in the present application is longer, so it is less likely to be blocked, so the electronic device disclosed in the present application has higher reliability.

[0035] The external air pressure balance hole 301 and the internal air pressure balance hole 302 in the above solution can be ports at two ends of the air pressure balance channel 303. Alternatively, the external air pressure balance hole 301 and the internal air pressure balance hole 302 penetrate the side wall of the air pressure balance channel 303 to achieve communication with the air pressure balance channel 303.

[0036] In an optional solution, the decorative member 300 is an annular structure as a whole, and the decorative member 300 is a decorative ring 330. The decorative member 300 is arranged around the optical module 200, that is, the light-transmitting area mentioned above is a light-transmitting hole. In this case, the external air pressure balance hole 301, the internal air pressure balance hole 302 and the air pressure balance channel 303 can all be opened on the decorative member 300.

[0037] In another optional solution, the decorative member 300 may include a lens 310, a first bonding portion 320 and a decorative ring 330 stacked in sequence. At this time, the lens 310 is bonded to the decorative ring 330 through the first bonding portion 320. The decorative ring 330 here is an annular structure, and the decorative ring 330 can be arranged around the optical module 200. Part of the area of ​​the lens 310 is a light-transmitting area, and the decorative ring 330 is sealed and connected to the device housing 100. The decorative member 300 of this structure can cover the through hole 101 as a whole, and the optical module 200 can work through the light-transmitting area. It should be noted that the first bonding portion 320 needs to avoid the light-transmitting area, and for this reason, the first bonding portion 320 can be a ring structure. The decorative member 300 in this solution has better protection and aesthetics.

[0038] Optionally, the first bonding portion 320 may be a double-sided tape, glue or the like. Of course, it may also be other bonding structures, which is not limited herein.

[0039] In the above embodiment, at least one of the lens 310, the first bonding portion 320 and the decorative ring 330 can form an air pressure balance channel. In this case, the external air pressure balance hole 301, the internal air pressure balance hole 302 and the air pressure balance channel 303 can all be opened on the lens 310, the first bonding portion 320 or the decorative ring 330.

[0040] However, since the overall length of the air pressure balance channel 303 is relatively long, the air pressure balance channel 303 is provided separately on the lens 310 , the first bonding portion 320 or the decorative ring 330 , which makes the processing of the air pressure balance channel 303 relatively difficult.

[0041] Based on this, in another optional embodiment, an air pressure balance channel 303 can be formed between at least two of the lens 310, the first bonding portion 320 and the decorative ring 330. In this solution, the air pressure balance channel 303 is formed by splicing two adjacent components. Compared with the method of separately setting the air pressure balance channel 303 on the lens 310, the first bonding portion 320 or the decorative ring 330, the processing method of splicing two components to form the air pressure balance channel 303 is simpler in molding, less difficult in processing and lower in cost.

[0042] Optionally, a partial assembly gap between the lens 310 and the first bonding portion 320 may form an air pressure balance channel 303. Alternatively, a partial assembly gap between the first bonding portion 320 and the decorative ring 330 may form an air pressure balance channel 303.

[0043] In another optional embodiment, one of the lens 310, the first bonding portion 320 and the decorative ring 330 may form a recessed structure, and the other or both of them cover the recessed structure, thereby forming the air pressure balance channel 303. Therefore, the recessed structure provided on one of them is an open structure, which is more convenient for demolding and manufacturing. Therefore, the difficulty of molding the air pressure balance channel 303 is reduced.

[0044] Furthermore, if Figure 4 and Figure 5 As shown, a strip groove 3301 may be provided on one side of the decorative ring 330 facing the first adhesive portion 320, and the first adhesive portion 320 may cover the notch of the strip groove 3301 to form the air pressure balance channel 303. In this solution, the strip groove 3301 is easier to demould and process, thereby further reducing the difficulty of forming the air pressure balance channel 303. In addition, the first adhesive portion 320 can cover the strip groove 3301, so the strip groove 3301 cannot be seen from the outside of the electronic device, thereby improving the aesthetics of the electronic device. In addition, since the decorative ring 330 is the installation body of the decorative part 300, the thickness of the decorative ring 330 is generally large, and the groove depth that can be set is deeper, so that the air pressure balance channel 303 with a larger cross section can be obtained without affecting the strength of the decorative ring 330.

[0045] In another optional embodiment, if Fig. 9 and Fig.10As shown, the first bonding portion 320 is provided with a strip hole 321 that penetrates along the thickness direction thereof. The thickness direction here can also be understood as the axial direction of the through hole 101. The lens 310 and the decorative member 300 respectively cover the openings on both sides of the strip hole 321 to form an air pressure balance channel 303. In this solution, the strip hole 321 penetrates the first bonding portion 320 so that the depth of the strip hole 321 is large, thereby making the cross-sectional area of ​​the air pressure balance channel 303 large, and further making the air pressure balance channel 303 not easily blocked. In addition, the main structure of the air pressure balance channel 303 is opened on the first bonding portion 320, so it is not easy to affect the strength of the decorative ring 330.

[0046] In the above embodiment, the lens 310, the first bonding portion 320 or the decorative ring 330 is provided with an external air pressure balance hole 301. However, the number of holes provided on the outer surface of the electronic device is large, resulting in poor appearance consistency of the electronic device, thus affecting the aesthetics of the electronic device.

[0047] Based on this, in another optional embodiment, at least a portion of the assembly gap between at least two of the lens 310, the first adhesive portion 320, and the decorative ring 330 can form an external air pressure balance hole 301. In this solution, the external air pressure balance hole 301 is formed by at least a portion of the assembly gap between at least two of the lens 310, the first adhesive portion 320, and the decorative ring 330, so the number of openings on the outer surface of the electronic device can be reduced, thereby improving the appearance consistency of the electronic device, thereby making the electronic device more aesthetically pleasing.

[0048] In another optional embodiment, the decorative ring 330 may be provided with an internal air pressure balance hole 302. Since the decorative ring 330 is closer to the inner cavity of the device housing 100, providing the internal air pressure balance hole 302 on the decorative ring 330 can simplify the manufacturing process.

[0049] In another optional embodiment, the decorative ring 330 may include a first ring body 331 and a second ring body 332, and the first ring body 331 may be arranged around the optical module 200. The lens 310, the first bonding portion 320 and the first ring body 331 are stacked in sequence, and the lens 310 is bonded to the first ring body 331 through the first bonding portion 320. The second ring body 332 may be arranged around the lens 310 and the first ring body 331. The first ring body 331 or the second ring body 332 may be sealed and connected to the device housing 100. Specifically, the first ring body 331 or the second ring body 332 may be bonded to the device housing 100 through the second bonding portion 340 mentioned above. The first ring body 331 is sealed and connected to the second ring body 332, and specifically, the first ring body 331 and the second ring body 332 may be bonded through the third bonding portion 350. The third bonding portion 350 may be a double-sided adhesive, glue, or other structures, and of course, may also be other structures, which are not limited herein.

[0050] At least two of the lens 310 , the first bonding portion 320 and the first ring body 331 may form an air pressure balance channel 303 . An internal air pressure balance hole 302 may be provided in the first ring body 331 .

[0051] The external air pressure balance hole 301 may include a first hole segment 301a and a second hole segment 301b. The assembly gap between the lens 310 and the second ring body 332 may form the first hole segment 301a, and the assembly gap between the first bonding portion 320 and the second ring body 332 may form the second hole segment 301b. One end of the first hole segment 301a may be connected to the external environment of the electronic device, and the other end of the first hole segment 301a may be connected to the second hole segment 301b. The first hole segment 301a may be connected to the air pressure balance channel 303 through the second hole segment 301b.

[0052] In this solution, the first circle body 331 is used to support the lens 310, and the second circle body 332 surrounds the lens 310. At this time, the first circle body 331 and the second circle body 332 form an annular groove structure, so part of the external air pressure balance hole 301 and the air pressure balance channel 303 form a bent channel structure, thereby increasing the complexity of the air pressure balance structure in the present application, thereby further improving the waterproof and dustproof performance of the electronic device.

[0053] In order to further improve the waterproof and dustproof performance of the electronic device, in another optional embodiment, as Figure 4 and Fig. 9 As shown, the first ring body 331 may include a first ring body 3311 and a first annular protrusion 3312 stacked with each other, and at least a portion of the first ring body 3311 is located in the device housing 100 and is sealed and connected to the device housing 100. Specifically, the first ring body 3311 is connected to the inner wall of the device housing 100 through the second adhesive portion 340 mentioned above. The first annular protrusion 3312 is opposite to the through hole 101, and at least a portion of the first annular protrusion 3312 protrudes from the device housing 100, and the first annular protrusion 3312 is arranged around the optical module 200. At this time, at least a portion of the first annular protrusion 3312 protrudes to the outer surface of the device housing 100 through the through hole 101.

[0054] The second ring body 332 is located outside the device housing 100, and includes a second ring body 3321 and a second annular protrusion 3322 that overlap each other. A portion of the second ring body 3321 can be located between the first bonding portion 320 and the first ring body 3311, and the second ring body 3321 is sealed and connected to the first ring body 3311. The second ring body 3321 is arranged around the first annular protrusion 3312, and the second annular protrusion 3322 can be arranged around the lens 310. Specifically, the second ring body 3321 and the first ring body 3311 can be bonded by the third bonding portion 350 mentioned above.

[0055] An air pressure balance channel 303 may be formed between at least two of the lens 310, the first bonding portion 320 and the first annular protrusion 3312. The assembly gap between the lens 310 and the second annular protrusion 3322 may form a first hole section 301a, and the assembly gap between the first bonding portion 320 and the second ring body 3321 may form a second hole section 301b.

[0056] In this solution, the assembly gap between the lens 310 and the second annular protrusion 3322 forms the first hole segment 301a, and the assembly gap between the first bonding portion 320 and the second ring body 3321 can form the second hole segment 301b. Since part of the second ring body 3321 is located below the first bonding portion 320, the second ring body 3321 and the second annular protrusion 3322 form an "L"-shaped structure, so that the first hole segment 301a and the second hole segment 301b form an "L"-shaped structure, so that the external air pressure balance hole 301 is a bent structure, thereby further increasing the complexity of the external air pressure balance hole 301, making it easier for water vapor and dust to settle, and further improving the waterproof and dustproof performance of the electronic device.

[0057] In the above embodiment, the width of the first hole segment 301a can be 0.05mm, which means that the single-side gap between the second annular protrusion 3322 and the lens 310 is 0.05mm. The width of the second hole segment 301b can be 0.08mm, which means that the gap between the second ring body 3321 and the first bonding portion 320 is 0.08mm. Of course, the widths of the first hole segment 301a and the second hole segment 301b can also be other sizes, which are not limited herein.

[0058] In the above embodiment, the internal air pressure balance hole 302 may pass through the first annular protrusion 3312 and the first ring body 3311, or may only pass through the first annular protrusion 3312. The specific opening position of the internal air pressure balance hole 302 is not limited herein.

[0059] In the above embodiment, the first circle body 331 may be provided with a communication port 3313, and one end of the communication port 3313 away from the air pressure balance channel 303 penetrates the outer wall of the first circle body 331, and the second hole section 301b and the air pressure balance channel 303 are connected through the communication port 3313. During the installation process of the first circle body 331 and the second circle body 332, there is a risk of misalignment and deflection, so that the communication port 3313 is blocked by the second circle body 332, thereby making the reliability of the electronic device poor.

[0060] Based on this, in another optional embodiment, the first circle body 331 may be provided with a first communication port 3313a and a second communication port 3313b, and the ends of the first communication port 3313a and the second communication port 3313b away from the air pressure balance channel 303 may penetrate the outer wall of the first circle body 331. The first communication port 3313a and the second communication port 3313b may be arranged at intervals along the circumference of the first circle body 331. The first communication port 3313a and the second communication port 3313b may both be used to connect the second hole section 301b and the air pressure balance channel 303.

[0061] In this solution, the first communication port 3313a and the second communication port 3313b can be arranged at intervals along the circumference of the first ring body 331. Therefore, even if one of the first communication port 3313a and the second communication port 3313b is blocked, the second hole section 301b and the air pressure balance channel 303 can be connected through the other one, thereby improving the reliability of the electronic device.

[0062] Furthermore, the first communication opening 3313a and the second communication opening 3313b may be symmetrically distributed about the central axis of the first circle body 331 . This solution can further reduce the risk of the communication opening being blocked.

[0063] In another optional embodiment, the first circle body 331 may include a first area and a second area, and the communication port 3313 may be opened in the second area. The gap between the first area and the second circle body 332 may be a first gap 410, and the gap between the second area and the second circle body 332 may be a second gap 420. The first gap 410 may be smaller than the second gap 420. In this solution, in the first circle body 331 and the second circle body 332, the gap between the area where the communication port 3313 is located and the second circle body 332 is larger, thereby avoiding the risk of the communication port 3313 being blocked, thereby improving the reliability of the electronic device.

[0064] Optionally, the first gap 410 may be 0.1 mm, and the second gap 420 may be 0.2 mm. Of course, the first gap 410 and the second gap 420 may also be other values, which are not limited herein.

[0065] Specifically, the connecting port 3313 can be opened on the above-mentioned first annular protrusion 3312. Since the second ring body 3321 is arranged around the first annular protrusion 3312, the first gap 410 and the second gap 420 here are the gaps between the outer wall of the first annular protrusion 3312 and the inner wall of the second ring body 3321.

[0066] In another solution, the first circle body 331 may be provided with the first communication port 3313a and the second communication port 3313b mentioned above, and the first circle body 331 includes at least two second areas mentioned above, the first communication port 3313a is provided in one of the second areas, and the second communication port 3313b is provided in another second area. This solution can further avoid the risk of the communication port 3313 being blocked, thereby improving the reliability of the electronic device.

[0067] In another optional embodiment, the air pressure balance channel 303 may include a plurality of arc-shaped channels and at least one connecting channel, wherein the plurality of arc-shaped channels are spaced apart, each arc-shaped channel may extend along the circumference of the decorative element 300, and two adjacent arc-shaped channels are connected through the connecting channel. The external air pressure balance hole 301 and the internal air pressure balance hole 302 are connected to different arc-shaped channels. In this case, the external air pressure balance hole 301 and the internal air pressure balance hole 302 are respectively connected to adjacent or spaced arc-shaped channels.

[0068] This solution can further increase the path and complexity of the air pressure balance channel 303, thereby making it difficult for water vapor and dust to spread into the electronic device, thereby further improving the waterproof and dustproof performance of the electronic device.

[0069] Specifically, the plurality of arc-shaped channels may respectively include a first arc-shaped channel 3031, a second arc-shaped channel 3032, and a third arc-shaped channel 3033 which are arranged concentrically. The radius of the first arc-shaped channel 3031 may be the same as the radius of the third arc-shaped channel 3033, and the radius of the second arc-shaped channel 3032 may be smaller than the radius of the first arc-shaped channel 3031. At this time, the first arc-shaped channel 3031 and the third arc-shaped channel 3033 are spaced apart along the circumference of the decorative element 300, and the second arc-shaped channel 3032 and the first arc-shaped channel 3031 or the third arc-shaped channel 3033 are spaced apart along the radial direction of the decorative element 300. Since the radius of the second arc-shaped channel 3032 is smaller than the radius of the first arc-shaped channel 3031, the second arc-shaped channel 3032 is close to the middle area of ​​the decorative element 300, while the first arc-shaped channel 3031 and the third arc-shaped channel 3033 are close to the edge area of ​​the decorative element 300.

[0070] The at least one connecting channel includes a first connecting channel 3034 and a second connecting channel 3035 , respectively. The first connecting channel 3034 can connect the first arc-shaped channel 3031 with the second arc-shaped channel 3032 , and the second connecting channel 3035 can connect the second arc-shaped channel 3032 with the third arc-shaped channel 3033 .

[0071] The external air pressure balance hole 301 may be communicated with the first arc-shaped channel 3031 , and the internal air pressure balance hole 302 may be communicated with the third arc-shaped channel 3033 .

[0072] This solution can not only increase the complexity of the path of the air pressure balance channel 303, but also make the structure of the air pressure balance channel 303 more regular, which is convenient for manufacturing and processing.

[0073] Of course, the structure of the air pressure balance channel 303 is not limited to the above structure, and may also be other structures which are not limited herein.

[0074] Optionally, the angle between the connecting channel and the curved channel may be 30°, 45°, or 60°. Of course, the angle between the connecting channel and the curved channel may also be other angles, which are not limited herein.

[0075] The connecting channel here can also be connected to the connecting port 3313 mentioned above, or the connecting port 3313 is the connecting channel, that is, the first connecting port 3313a and the second connecting port 3313b mentioned above are two connecting channels connected to the first arc-shaped channel 3031 respectively.

[0076] In order to further improve the waterproof and dustproof performance of the electronic equipment, in another optional embodiment, the arc channel includes a main section and a branch section, and the main section and the branch section can be located on both sides of the connecting channel respectively. It can also be understood that one end of the connecting channel is connected to the main section and the branch section at the same time. The main sections of adjacent arc channels are connected through the connecting channel. The internal air pressure balance hole 302 is connected to one of the main sections, and the angle between the main section and the connecting channel is greater than 0° and less than 90°. The angle between the main section and the connecting channel here can be understood as the angle between one of the tangents of the main section and one of the tangents of the connecting channel. At this time, the external air pressure balance hole 301 and the internal air pressure balance hole 302 are connected through multiple main sections and multiple connecting channels.

[0077] In this scheme, the angle between the main section and the connecting channel is greater than 0° and less than 90°, which can also be understood as the angle between the main section and the connecting channel is an acute angle. On the contrary, the angle between the connecting channel and the branch section is the supplementary angle between the main section and the connecting channel, so the angle between the main section and the connecting channel is an obtuse angle. At this time, water vapor and dust are more likely to flow into the branch section, and most of the water vapor and dust can enter the main section only after turning back in the branch section. Therefore, the branch section can extend the sedimentation path of water vapor and dust, and can further prevent water vapor and dust from entering the electronic equipment, thereby further improving the waterproof and dustproof performance of the electronic equipment.

[0078] In a specific solution, the first connecting port 3313a and the second connecting port 3313b mentioned above are two connecting channels connected to the first arcuate channel 3031, respectively. The first connecting port 3313a divides the first arcuate section into the first main section 3031a and the first branch section 3031b, and the second connecting port 3313b is connected to the first main section 3031a. One end of the first connecting channel 3034 is connected to the end of the first main section 3031a away from the first connecting port 3313a, and the other end of the first connecting channel 3034 divides the second arcuate section 3032 into the second main section 3032a and the second branch section 3032b. One end of the second connecting channel 3035 is connected to the end of the second main section 3032a away from the second branch section 3032b, and the other end of the second connecting channel 3035 divides the third arcuate channel 3033 into the third main section 3033a and the third branch section 3033b. The internal air pressure balance hole 302 is connected to the third main section 3033a.

[0079] In the specific waterproof and dustproof process, such as Fig.13 In the propagation path shown by the solid arrow, most of the dust and water vapor entering the first connecting port 3313a first enters the first branch section 3031b, and then returns from the first branch section 3031b to enter the first main section 3031a. Then, it enters the second branch section 3032b through the first connecting channel 3034, and then returns from the second branch section 3032b to enter the second main section 3032a. Then, it enters the third branch section 3033b through the second connecting channel 3035, and finally enters the third main section 3033a. At this point, most of the dust and water vapor have settled after a long propagation process, so the waterproof and dustproof performance of the electronic device can be better improved.

[0080] Similarly, if Fig.13In the propagation path of the dotted arrow, most of the dust and water vapor entering the second connecting port 3313b first enters the first main section 3031a, and then most of the dust and water vapor propagates along the first main section 3031a toward the first branch section 3031b, and then returns to the first main section 3031a. Then, it enters the second branch section 3032b through the first connecting channel 3034, and then returns from the second branch section 3032b to enter the second main section 3032a. Then, it enters the third branch section 3033b through the second connecting channel 3035, and finally enters the third main section 3033a. At this time, most of the dust and water vapor have settled after a long propagation process, so the waterproof and dustproof performance of the electronic device can be better improved.

[0081] In another optional embodiment, a plurality of ash storage grooves 500 are provided on the side wall of the air pressure balance channel 303, and the plurality of ash storage grooves 500 can be distributed at intervals along the extension direction of the air pressure balance channel 303. In this solution, the ash storage grooves 500 are equivalent to increasing the depth of a portion of the side wall of the air pressure balance channel 303, thereby avoiding the risk of the air pressure balance channel 303 being blocked.

[0082] Specifically, in Figure 4 In the above solution, the ash storage groove 500 is opened on the bottom of the strip groove 3301.
