Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a seal, a functional component and an electronic device. Background Art

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely 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.

[0046] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0047] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0048] Combination Figure 1 and Figure 2 As shown, the embodiment of the present application provides a sealing member 100, and the sealing member 100 is provided with at least one air flow channel 110. The air flow channel 110 includes a first opening 111 and a second opening 112 that are connected, and the first opening 111 and the second opening 112 are respectively located on different sides of the sealing member 100. Thus, gas can flow in the air flow channel 110 to achieve an exhaust function.

[0049] The inner wall of the airflow channel 110 is provided with a hydrophobic structure. It should be noted that the hydrophobic structure has a certain hydrophobicity, that is, the hydrophobic structure has the property of mutually repelling water. By providing a hydrophobic structure on the inner wall through which the airflow passes, it is possible to prevent water from flowing between the first opening 111 and the second opening 112, thereby achieving a better waterproof effect. It can be seen from the above that the seal 100 provided in the embodiment of the present application is not only capable of exhausting, but also has a high waterproof property.

[0050] The following is combined with Figures 1 to 7 The various components, structures and functions of the seal 100 provided in the embodiment of the present application are described in more detail.

[0051] like Figure 1 As shown, in some embodiments, when there are a plurality of airflow channels 110 , the plurality of airflow channels 110 are spaced apart and distributed on the sealing member 100 .

[0052] It should be noted that the multiple airflow channels 110 are distributed at intervals on the seal 100, which means that the multiple airflow channels 110 can be distributed at intervals on a part of the seal 100 or on the entire seal 100. The distribution at intervals means that the distance between two adjacent airflow channels 110 is a preset distance.

[0053] It is understandable that by distributing a plurality of airflow channels 110 at intervals on the seal 100 , the pressure can be reduced more gradually during exhaust pressure relief using the seal 100 , that is, a more uniform pressure relief process can be achieved.

[0054] like Figure 1 As shown, in some embodiments, the seal 100 is annular, a plurality of air flow channels 110 are spaced apart along the circumference of the ring, and the first opening 111 and the second opening 112 are respectively located on both sides of the ring in the thickness direction of the seal 100 .

[0055] With such arrangement, the gas can enter the annular channel from one side of the annular seal 100 along each of the circumferential airflow channels 110 of the seal 100, and then be discharged from the other side of the annular seal 100 to the outside of the seal 100, so that the seal 100 can achieve an exhaust effect. Since the plurality of airflow channels 110 are distributed at intervals along the circumferential direction of the ring, it can be ensured that the gas flowing to the seal 100 from each position can enter from one side of the seal 100 and then be discharged from the other side of the seal 100, thereby achieving a better exhaust effect.

[0056] Combination Figure 1 and Figure 2 As shown, in some embodiments, the inner diameter of the air flow channel 110 gradually increases from the first opening 111 to the second opening 112 .

[0057] It should be noted that the gas generally enters the airflow channel 110 from the first opening 111, and then flows out from the second opening 112 to the outside of the seal 100. Since the inner diameter of the first opening 111 is small and the inner diameter of the second opening 112 is large, it can be ensured that the gas flowing into the airflow channel 110 can be quickly discharged from the second opening 112, thereby improving the exhaust efficiency. In addition, since the inner diameter of the first opening 111 is small, it can be ensured that the water flowing into the airflow channel 110 from the second opening 112 cannot flow out from the first opening 111, thereby achieving a better waterproof effect, that is, the water cannot flow in the seal 100. In other words, the seal 100 can have both good exhaust effect and waterproof performance.

[0058] In some embodiments, the aperture of the first opening 111 is less than 20 μm. It should be noted that the aperture of the first opening 111 refers to the diameter of the first opening 111. In some embodiments, the aperture of the second opening 112 is 50 μm to 100 μm. It should be noted that the aperture of the second opening 112 refers to the diameter of the second opening 112.

[0059] It can be understood that by setting the aperture of the first opening 111 and the aperture of the second opening 112 according to the above dimensions, it can ensure that the sealing element 100 can achieve a good exhaust effect and also have a good waterproof performance.

[0060] In some embodiments, the hydrophobic structure is a micro-nano hydrophobic structure.

[0061] It should be noted that the micro-nano hydrophobic structure refers to a structure with micron or nanometer size and good hydrophobic performance. It is understandable that by arranging the micro-nano hydrophobic structure on the inner wall of the airflow channel 110, it is possible to better prevent the water flowing into the airflow channel 110 from the second opening 112 from flowing out from the first opening 111, thereby achieving a good waterproof effect and preventing the water from flowing out from the first opening 111 and causing damage to other devices around the seal 100. The micro-nano hydrophobic structure can be a micro-nano structure with super-hydrophobic properties. The super-hydrophobic property means that the surface of the super-hydrophobic structure is highly hydrophobic and extremely difficult to be wetted. The contact angle between the water droplet and the super-hydrophobic structure exceeds 150°, thereby ensuring that the seal 100 has good waterproof performance.

[0062] In some embodiments, the micro-nano hydrophobic structure is a micro-nano hydrophobic particle.

[0063] It should be noted that the number of micro-nano hydrophobic particles is multiple. The micro-nano hydrophobic particles can be arranged in a certain direction on the inner wall of the airflow channel 110, or can be arranged in a disorderly direction on the inner wall of the airflow channel 110. It is understandable that, since the micro-nano hydrophobic particles are small, they will not hinder the normal exhaust process of the airflow channel 110, and at the same time, the seal 100 can have better waterproof performance.

[0064] like Figure 2 As shown, in some embodiments, the seal 100 includes a first portion 120 and a second portion 130 , the second portion 130 is protruding from the first portion 120 , and the airflow channel 110 is located in the second portion 130 ; or, the airflow channel 110 is located in the first portion 120 .

[0065] It should be noted that the seal 100 is generally disposed between two components, and the seal 100 may be subjected to a certain degree of compression. By providing the seal 100 with the second portion 130 protruding from the first portion 120, the strength and pressure resistance of the seal 100 can be improved.

[0066] In some embodiments, the airflow channel 110 is formed by laser processing. It should be noted that the material of the seal 100 can be TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber) material. Laser processing can be achieved by laser processing technology such as ultraviolet laser processing technology, femtosecond laser processing technology or carbon dioxide laser processing technology. For example, when ultraviolet laser processing technology is used, the laser energy can be 15W to 20W. During laser processing, parameters such as laser speed, laser energy, and laser type can be adjusted based on the aperture of the first opening 111, the aperture of the second opening 112, and the length of the airflow channel 110. It can be understood that the laser energy generally decreases as the depth of the laser entering the TPU increases.

[0067] It should be noted that during the laser processing and forming process, the seal 100 is melted by heat, and the melted TPU particles will splash onto the inner wall of the airflow channel 110. After being re-bonded to the inner wall of the airflow channel 110, a micro-nano hydrophobic structure will be formed on the inner wall of the airflow channel 110. The micro-nano hydrophobic structure has super hydrophobic properties, which can effectively prevent water molecules from flowing out of the first opening 111, thereby providing a guarantee for the waterproof effect of the seal 100.

[0068] Combination Figure 1 and Figure 2As shown, in some embodiments, the first portion 120 is provided with a through slot 121. The second portion 130 is arranged around the side wall of the through slot 121, and the second portion 130 is protrudingly arranged on the outer side wall of the through slot 121, and the opening direction of the first opening 111 and the second opening 112 is along the opening direction of the through slot 121. Alternatively, at least one end surface of the through slot 121 is protrudingly provided with the second portion 130, and the opening direction of the first opening 111 and the second opening 112 is at a preset angle to the opening direction of the through slot 121. Thus, the flexibility of setting the airflow channel 110 is improved.

[0069] It should be noted that the through slot 121 generally has two openings facing each other. In the embodiment of the present application, the opening direction of the first opening 111 and the second opening 112 is along the opening direction of the through slot 121, which means that when laser processing is performed, the direction of the laser irradiating the second portion 130 is consistent with the direction from one opening of the through slot 121 to the other opening. The opening direction of the first opening 111 and the second opening 112 is at a preset angle to the opening direction of the through slot 121, which means that when laser processing is performed, the direction of the laser irradiating the second portion 130 is at a preset angle to the direction from one opening of the through slot 121 to the other opening.

[0070] like Figure 1 As shown, in some embodiments, the through groove 121 includes a first inner wall 1211 and a second inner wall 1212 opposite to each other, and at least one reinforcing rib 1213 is provided between the first inner wall 1211 and the second inner wall 1212. The two ends of the reinforcing rib 1213 are respectively connected to the first inner wall 1211 and the second inner wall 1212. It can be understood that by providing the reinforcing rib 1213, the strength of the sealing member 100 can be increased to prevent the sealing member 100 from being deformed. It should be noted that the reinforcing rib 1213 and the first inner wall 1211 and the second inner wall 1212 are an integrally formed structure.

[0071] It can be seen from the above that the use of the seal 100 provided in the embodiment of the present application can not only ensure that the seal 100 can achieve the exhaust and pressure relief process more evenly, so that the gas can be discharged more smoothly from the second opening 112, but also enable the seal 100 to have better waterproof performance.

[0072] Combination Figures 1 to 7As shown, the embodiment of the present application also provides a functional component, which includes a main body 200 and a sealing member 100 as described in any of the above items, and the sealing member 100 is connected to the main body 200. It should be noted that the sealing member 100 in the embodiment of the present application is the same as the components and corresponding functions of the sealing member 100 provided in the above-mentioned embodiment of the present application, so the embodiment of the present application will not be repeated here. Since the sealing member 100 can not only exhaust air, but also has high waterproofness, when the sealing member 100 is connected to the main body 200, it can not only discharge the gas from the inside of the main body 200 to the outside of the main body 200, but also prevent the water on the outside of the main body 200 from flowing into the inside of the main body 200, thereby damaging the main body 200. It should be noted that the main body 200 can be a card holder, an audio component or a side key in an electronic device.

[0073] In some embodiments, the seal 100 is disposed on the body 200. It should be noted that the seal 100 can be sleeved on the body 200 or abut against the side wall of the body 200. For example, when the body 200 is a side key or a Figure 1 In the case of the card holder shown in the figure, a section of the side wall of the main body 200 in the extension direction is sleeved in the through groove 121 of the sealing member 100 along the circumferential direction; or in combination with Figure 7 As shown, when the main body 200 is an audio component, any side wall of the main body 200 abuts against one end surface of the sealing component 100 .

[0074] Combination Figure 5 and Figure 6 As shown, in some embodiments, a groove 210 is provided on the side wall of the body member 200. The sealing member 100 includes a first portion 120 and a second portion 130, wherein the first portion 120 is inserted into the groove 210, and the second portion 130 is connected to the first portion 120 and protrudes in a direction away from the groove 210. The airflow channel 110 is located in the second portion 130. It can be understood that since the first portion 120 is inserted into the groove 210, the stability of the connection between the sealing member 100 and the body member 200 can be increased, thereby avoiding the situation where the sealing member 100 is separated from the body member 200 and the two sides of the body member 200 cannot be vented or waterproofed.

[0075] like Figure 3 , Figure 4 and Figure 5 As shown, when the body 200 is a card holder, in some embodiments, a section of the side wall of the body 200 in the extension direction is provided with an annular groove along the circumferential direction, the first portion 120 of the seal 100 is inserted into the annular groove, and the second portion 130 is connected to the first portion 120 and protrudes in a direction away from the bottom of the annular groove. The airflow channel 110 is located in the second portion 130.

[0076] like Figure 7 As shown, when the main body 200 is an audio component, in some embodiments, the main body 200 includes a plurality of side walls located in different planes, and any of the plurality of side walls is provided with a groove 210. The sealing member 100 is inserted into the groove 210, and the airflow channel 110 is arranged on the main body 200. In other embodiments, the main body 200 includes a plurality of side walls located in different planes, and any of the plurality of side walls is provided with a groove 210. The first portion 120 of the sealing member 100 is inserted into the groove 210, and the second portion 130 is connected to the first portion 120 and protrudes in a direction away from the bottom of the groove 210. The airflow channel 110 is located in the second portion 130. For example, the main body 200 may be a cuboid, and a groove 210 is provided on any surface of the cuboid, and the depth direction of the groove 210 is perpendicular to the surface.

[0077] It is understandable that if the functional component is set inside the electronic device, the seal 100 connected to the main body 200 can be used to discharge the gas inside the electronic device through the first opening 111 and the second opening 112 in sequence to the outside of the electronic device, that is, the gas inside the electronic device can be smoothly exhausted and depressurized, thereby preventing other components in the electronic device from being squeezed and affecting normal use. For example, it can prevent the diaphragm of components such as speakers from being squeezed, deformed or offset to produce noise or abnormal sound.

[0078] Combination Figures 1 to 7 As shown, the embodiment of the present application also provides an electronic device, the electronic device includes: a seal 100 as described in any one of the embodiments of the present application, or a functional component as described in any one of the embodiments of the present application. It should be noted that the seal 100 in the embodiment of the present application is the same as the components of the seal 100 provided in the embodiment of the present application, or the components of the functional components provided in the embodiment of the present application are the same as the components of the functional components provided in the embodiment of the present application, so the embodiment of the present application is not repeated here. The electronic device can be an electronic device such as a smart wearable device, a mobile phone, a tablet, a vehicle, a camera, a power bank, a robot, etc., which needs to exhaust and release the pressure inside and prevent the external water flow from entering the inside. Due to the use of the seal 100 or the functional component composed of the seal 100 and the main body 200, the gas inside the electronic device can be smoothly exhausted and released, and the air pressure inside the whole electronic device is balanced, thereby avoiding other components in the electronic device from being pressed or squeezed to affect normal use, for example, it can avoid the situation where the diaphragm of components such as speakers is squeezed and deformed or offset to produce noise or abnormal sound, ensuring that the user can use the electronic device normally and improving the user experience.

[0079] like Figure 6As shown, in some embodiments, the electronic device further comprises a first carrier 300. The first carrier 300 is provided with a mounting hole 310, through which a portion of the body 200 penetrates into the interior of the electronic device, and the sealing member 100 is located between the body 200 and the mounting hole 310.

[0080] Among them, the gas inside the electronic device can pass through the first opening 111 and the second opening 112 in sequence and flow out to the outside of the electronic device. It should be noted that the first carrier 300 can be a middle frame inside the electronic device. The main body 200 can be a structure such as a card holder or a side key. In some embodiments, the outer end of the main body 200 is connected to a protective shell 220, and the protective shell 220 is located outside the first carrier 300 and covers the mounting hole 310. Thereby, it is possible to further prevent external water from flowing into the interior of the electronic device, which can not only protect the main body 200, but also improve the waterproof performance of the electronic device. For example, the main body 200 can be a card holder, and the protective shell 220 can be a card holder cap wrapped around the outer end of the main body 200. In this way, the gas inside the electronic device can be discharged smoothly to the outside of the electronic device, avoiding the situation where the diaphragm of the speaker and other components in the electronic device cannot be used normally due to abnormal sound or noise due to pressure.

[0081] like Figure 7 As shown, in some embodiments, the electronic device further comprises a second carrier 400 . The second carrier 400 is provided with a mounting groove 410 , the opening of which faces the interior of the electronic device, and the sealing member 100 is located between the body 200 and the bottom of the mounting groove 410 .

[0082] Among them, the gas inside the electronic device can pass through the first opening 111 and the second opening 112 in sequence and flow out to the outside of the electronic device. It should be noted that the second carrier 400 can be a middle frame inside the electronic device. The main body 200 can be a structure such as an audio component, and the seal 100 can be an annular seal 100, and the end faces of the seal 100 are respectively against the bottom of the groove of the mounting groove 410 and the bottom of the groove of the groove provided on the side wall of the main body 200. With such a configuration, the gas inside the electronic device can be smoothly discharged to the outside of the electronic device, avoiding the situation where the diaphragm of the speaker and other components in the electronic device cannot be used normally due to abnormal sound or noise caused by pressure.
