Detailed implementation manners

[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0047] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those skilled in the art.

[0048] 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.

[0049] Combination Figure 1 and Figure 2 As shown, in the first aspect, the embodiment of the present application provides a card tray assembly, which includes a sealing assembly 100, a first carrier 200 and a second carrier 300. The sealing assembly 100 is sleeved on the first carrier 200. The second carrier 300 is provided with a plug hole 310, and the first carrier 200 passes through the plug hole 310, so that the first carrier 200 and the second carrier 300 can be connected together. It should be noted that the first carrier 200 in the embodiment of the present application can be, for example, a card tray in an electronic device, and the second carrier 300 can be, for example, a middle frame in an electronic device.

[0050] In addition, the sealing component 100 is located in the socket 310, wherein the sealing component 100 can absorb water and change from the first form to the second form. When the sealing component 100 is in the first form, the sealing component 100 and the socket 310 are gap-matched, so that the airflow can flow out through the gap to achieve the exhaust function of the card tray assembly. When the sealing component 100 is in the second form, the sealing component 100 and the socket 310 are interference-fitted. Thus, the side of the sealing component 100 away from the first carrier 200 can be against the hole wall of the socket 310 to form a seal. In this way, when the electronic device where the card tray assembly is located is dry, it can be exhausted through the card tray assembly to avoid abnormal noise; when the electronic device encounters water, the sealing component 100 expands to prevent water from flowing in between the sealing component 100 and the hole wall of the socket 310, thereby achieving a waterproof effect. In other words, the card tray assembly provided in the embodiment of the present application can have both an exhaust function and a high waterproof performance.

[0051] The following is combined with Figures 1 to 7 The various components and functions of the card tray assembly provided in the embodiment of the present application are described in more detail.

[0052] Combination Figures 3 to 5 As shown, in some embodiments, the sealing assembly 100 includes a first sealing member 110 and a second sealing member 120. The first sealing member 110 and the second sealing member 120 are connected in the depth direction of the insertion hole 310. It should be noted that when the card tray assembly is exhausted, the gas is generally exhausted in the direction from the second sealing member 120 to the first sealing member 110. The water flow outside the card tray assembly flows to the card tray assembly in the direction from the first sealing member 110 to the second sealing member 120.

[0053] The first seal 110 and the second seal 120 are both in a state where the cross-section gradually increases in the direction from the first carrier 200 to the second carrier 300. In this way, there can be sufficient deformation space between the first seal 110 and the second seal 120 and the hole wall of the plug hole 310, and the side with a smaller cross-section of the first seal 110 can absorb a large amount of water and have an interference fit with the plug hole 310, ensuring that the gap between the plug hole 310 and the sealing assembly 100 is timely blocked when the sealing assembly 100 encounters water.

[0054] And at the connection between the first seal 110 and the second seal 120, the cross section of the first seal 110 is larger than the cross section of the second seal 120. In this way, the connection between the first seal 110 and the second seal 120 can provide sufficient deformation space, and the setting of the double-layer seal can further improve the waterproof performance of the card tray assembly.

[0055] Combination Figures 3 to 5 As shown, in some embodiments, the first sealing member 110 includes a first side surface 111 and a second side surface 112 opposite to each other in the thickness direction. The second sealing member 120 includes a third side surface 121 and a fourth side surface 122 opposite to each other in the thickness direction. The second side surface 112 is connected to the third side surface 121, and the first side surface 111 and the fourth side surface 122 are opposite to each other. It should be noted that the first sealing member 110 and the second sealing member 120 can be an integrally formed structure, or can be connected by bonding, abutting, etc.

[0056] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the outer diameter of the first seal 110 increases linearly from the first side 111 to the second side 112. Therefore, the first side 111 of the first seal 110 can absorb a large amount of water after encountering water, so as to be deformed into a state of interference fit with the plug hole 310. The outer diameter of the second seal 120 increases linearly from the third side 121 to the fourth side 122, and the outer diameter of the third side 121 is smaller than the outer diameter of the second side 112. Therefore, the connection between the third side 121 and the second side 112 can provide sufficient deformation space for the first seal 110 and the second seal 120 to achieve a better waterproof effect. Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the cross-section of the first sealing member 110 and the cross-section of the second sealing member 120 are both trapezoidal, so as to ensure that the first sealing member 110 and the second sealing member 120 have sufficient deformation space.

[0057] Combination Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the first seal 110 is provided with a first through hole 113, and the second seal 120 is provided with a second through hole 123. The first through hole 113 and the second through hole 123 are continuous and aligned in the depth direction of the socket 310. Thus, when the sealing assembly 100 is sleeved, it can avoid the situation that it is not easy to sleeve the sealing assembly 100 on the first carrier 200 due to the misalignment of the hole walls of the first through hole 113 and the second through hole 123. That is to say, it is more convenient to sleeve the sealing assembly 100 on the first carrier 200, improving the assembly efficiency.

[0058] In some embodiments, when the sealing assembly 100 is in the first form, the gap between the sealing assembly 100 and the hole wall of the socket 310 is less than 0.1 mm. It should be noted that within this gap range, not only can it ensure that the card tray assembly can achieve the exhaust function, but also ensure uniform pressure relief to achieve smooth exhaust.

[0059] Combined Figure 1 and Figure 6 As shown, in some embodiments, the first carrier 200 is provided with an annular groove 210 along the circumferential direction, and the sealing assembly 100 is sleeved in the annular groove 210. Thus, the sealing assembly 100 can be more stably sleeved together with the first carrier 200.

[0060] As Figure 6 shown, in some embodiments, the first carrier 200 is provided with at least one mounting hole 220. The card tray assembly further includes at least one support 400, and the support 400 is located in the corresponding mounting hole 220. One side of the sealing assembly 100 that abuts against the first carrier 200 includes opposite first side walls 130 and second side walls 140, and both ends of the support 400 are connected to the first side wall 130 and the second side wall 140 respectively. It can be understood that the support 400 can play a role in positioning and supporting the sealing assembly 100 to assemble the sealing assembly 100 more firmly with the first carrier 200.

[0061] As Figure 6As shown, in some embodiments, the first bearing member 200 includes a push portion 230 and a bearing portion 240 connected to each other. The push portion 230 can be pushed by force to move the bearing portion 240 along the axial direction of the jack 310. The bearing portion 240 is provided with a card slot 241, and the sealing assembly 100 is sleeved on the bearing portion 240. It should be noted that the push portion 230 can be, for example, a card cap of a card tray in an electronic device, and the bearing portion 240 can be a part of the card tray in the electronic device for arranging a SIM card. The push portion 230 can protect the bearing portion 240 and can also drive the bearing portion 240 to move. Generally, the bearing portion 240 is located inside the electronic device, and the side of the push portion 230 that is away from the bearing portion 240 is exposed to the outside of the electronic device. The gas in the electronic device generally passes through the bearing portion 240, the sealing assembly 100 and the push portion 230 in sequence and is discharged to the outside of the electronic device, and the water flow outside the electronic device generally flows from the outer surface of the push portion 230 to the card tray assembly.

[0062] like Figure 7 As shown, in some embodiments, the second carrier 300 includes a first body portion 320 and a second body portion 330 connected to each other, the first body portion 320 is a metal structure, and the second body portion 330 is a plastic structure. It should be noted that the first body portion 320 and the second body portion 330 can be injection molded, and the first body portion 320 with a metal structure can increase the strength of the second body portion 330. Figure 7 As shown, in some embodiments, the first body portion 320 has a third through hole 321, the second body portion 330 has a fourth through hole 331, and the third through hole 321 and the fourth through hole 331 are connected to form a plug hole 310. The pushing portion 230 is located in the third through hole 321, and the sealing assembly 100 is located in the fourth through hole 331. It should be noted that the sealing assembly 100 in the embodiment of the present application can be rubber, such as thermoplastic polyurethane rubber. Since the second body portion 330 is a plastic structure, the sealing assembly 100 made of rubber is arranged in the fourth through hole 331 of the second body portion 330, which can ensure that there is sufficient friction between the second body portion 330 and the sealing assembly 100 to avoid the position of the sealing assembly 100 from shifting.

[0063] In some embodiments, an annular groove 210 is provided on the circumferential side of one end of the bearing portion 240 close to the pushing portion 230. The end surface of one end of the bearing portion 240 close to the pushing portion 230 is connected to the end surface of one end of the pushing portion 230 close to the bearing portion 240. One end of the bearing portion 240 away from the pushing portion 230 passes through the third through hole 321 and the fourth through hole 331 in sequence and passes out of the second bearing member 300, and one end of the bearing portion 240 close to the pushing portion 230 is located in the third through hole 321 and the fourth through hole 331.

[0064] In some embodiments, the sealing assembly 100 includes a swelling material. It should be noted that the swelling material has swelling properties, that is, the swelling material will exhibit a phenomenon of volume expansion in a solvent. The swelling material is also called a superabsorbent material and has a high molecular compound, such as an ion exchange resin, whose structure is generally a linear or cross-linked polymer. The main feature is that it has a very strong water absorption capacity and can generally absorb hundreds or even thousands of times its own mass of water. After absorbing water, the swelling material will form a gel-like substance with good water retention properties. The swelling principle is mainly achieved through its molecular structure and chemical reactions. Generally, the molecular structure of the swelling material contains a large number of hydrophilic groups, such as carboxyl groups, hydroxyl groups, amino groups, etc. These groups can form hydrogen bonds with water molecules, thereby enhancing the interaction between the swelling material and water molecules. In addition, the swelling material also contains a cross-linking agent, which can cross-link the polymer chains into a three-dimensional network structure, thereby enhancing the stability and strength of the water-absorbing resin. Thus, when the card tray assembly encounters water, when water molecules pass through the sealing assembly 100, the volume of the sealing assembly 100 can quickly expand to fill the gap between the sealing assembly 100 and the jack 310, achieving an interference fit, and then hindering the entry of water molecules to achieve good waterproof performance. And because the swelling material has good water absorption, water molecules will be locked inside the swelling material and will not enter the electronic device. When the electronic device is removed from the water environment and dried, the swelling material will return to the dry state again, that is, the sealing assembly 100 can return from the second form to the first form, realizing a reversible physical change. In this way, not only can the assembly have high waterproof performance, but also the reusability and reliability of the card tray assembly can be improved.

[0065] In a second aspect, an embodiment of the present application further provides an electronic device, which includes the card tray assembly described in any one of the above first aspects. It should be noted that the composition and functions of the card tray assembly in the electronic device are the same as those of the card tray assembly provided in the embodiments of the present application, so the present application will not repeat them here. Since the card tray assembly can not only have an exhaust function but also have high waterproofness, the electronic device equipped with this card tray assembly can not only achieve exhaust but also have high waterproofness. Then, when the rear shell of the electronic device is squeezed, the gas inside the electronic device can be gently discharged, and it is not easy to produce noise or abnormal noise. At the same time, because the electronic device has good waterproof performance, it is not easy to be damaged when encountering water.

[0066] In the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The term "plurality" means two or more, unless otherwise clearly defined.

[0067] Other embodiments of the present application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include known common general knowledge or conventional technical means in the technical field not disclosed in the present application. The specification and examples are only to be considered as exemplary.

[0068] It should be understood that the present application is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present application is only limited by the appended claims.
