Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0043] The field of electronic technology is an emerging technology that began to develop from the late 19th century to the early 20th century. It developed most rapidly and was most widely used in the 20th century, becoming an important symbol of the development of modern science and technology. Electronic technology refers to the field of science and technology that studies electronic components, circuits, systems and their applications. It covers a wide range of content from basic theoretical research to complex system design and application, including analog signal processing, digital signal processing, microelectronics, integrated circuit design, communication technology, computer technology and other sub-fields. The development of electronic technology has greatly promoted the process of informatization and automation in modern society, and is an indispensable key technology in modern industry, medical care, transportation, communication and other fields. Electronic equipment, as its application carrier, refers to equipment composed of electronic components such as integrated circuits, transistors, and electron tubes, and uses electronic technology to play a role, including electronic computers and robots controlled by electronic computers, numerical control or program control systems, etc.

[0044] In many electronic equipment application scenarios, waterproof sealing is a very important design requirement. For example, outdoor equipment, underwater equipment, military equipment, and some consumer electronic products all require effective waterproof sealing measures to prevent moisture intrusion to avoid damaging sensitive electronic components or affecting the normal operation of the equipment. Waterproof sealing can not only extend the service life of the equipment, but also ensure safety and reliability in harsh environments. However, in electronic equipment, some designs fail to fully consider waterproof sealing, resulting in imperfect sealing, gaps between structures, water seepage problems, oxidation and short circuits of electronic components, and may cause problems such as static electricity strikes, thereby damaging hardware components. In one possible implementation, there is a gap between the card tray and the card slot, which is sealed with a sealing ring to reduce moisture infiltration and achieve a waterproof effect.

[0045] In order to solve the above problems, the present application further improves the electronic device and designs the following Figure 2 The structure shown squeezes the sealing ring to achieve a waterproof function. Specifically, the sealing ring is arranged on the card tray and close to the notch of the card slot, and the sealing ring is used to seal the gap between the card tray and the card slot.

[0046] Based on this, the embodiment of the present application discloses an electronic device, which uses magnetic force to squeeze the sealing ring, and uses the interference fit of the sealing ring to seal the gap at the fitting position to achieve a better waterproof effect. It can maintain a strong force to achieve higher sealing, and has strong adaptability to different working conditions, including high and low temperatures and different pressure ranges, thereby improving the safety of operation.

[0047] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0048] See also Figures 1 to 3 , Figure 1 is a schematic diagram of a three-dimensional structure of an electronic device 100 disclosed in an embodiment of the present application, Figure 2 is a partial cross-sectional view of an electronic device 100 disclosed in an embodiment of the present application, Figure 3 for Figure 2 The present application discloses an electronic device 100, which includes a housing 1, a card tray 2, a sealing ring 3 and a magnetic component 4. The housing 1 is provided with a card slot 11, the card tray 2 is detachably connected to the card slot 11 along a first direction X, and the sealing ring 3 is arranged at the notch of the card tray 2 and close to the card slot 11. The sealing ring 3 is used to seal the gap between the card tray 2 and the card slot 11. In this way, when the card tray 2 is inserted, the interference fit of the sealing ring 3 is used to close the gap at the fitting position to achieve a waterproof effect.

[0049] Combination Figures 2 to 5 , Figure 4 is a position relationship diagram of the magnetic part and the sealing ring 3 when the magnetic force F is an attractive force, Figure 5 : is a positional relationship diagram of the magnetic component and the sealing ring 3 when the magnetic force F is a repulsive force. Further, the magnetic component 4 includes a first magnetic component 41 and a second magnetic component 42, the first magnetic component 41 is fixedly connected to the housing 1, the second magnetic component 42 is arranged on the card tray 2 and can move relative to the card tray 2 along the first direction X, the first magnetic component 41 and the second magnetic component 42 are correspondingly installed along the first direction X, so that the first magnetic component 41 can apply a magnetic force F along the first direction X to the second magnetic component 42, and the magnetic force F can drive the second magnetic component 42 to move along the first direction X to squeeze the sealing ring 3.

[0050] In this way, when the card tray 2 is inserted into the housing 1, the first magnetic part 41 and the second magnetic part 42 are close to each other, the magnetic force F increases, and the second magnetic part 42 squeezes the sealing ring 3 to achieve a waterproof effect; when the card tray 2 is ejected, the first magnetic part 41 and the second magnetic part 42 are separated, the magnetic force F decreases, the squeezing force of the second magnetic part 42 on the sealing ring 3 decreases, the sealing ring 3 recovers its shape, and the resistance of the card tray 2 to ejecting is reduced. The sealing ring 3 is squeezed by the magnetic force F, which has strong stability and large force, and can achieve higher sealing performance. The magnetic part has strong adaptability and can adapt to different working conditions, including high and low temperatures and different pressure ranges, thereby improving the safety of operation.

[0051] Specifically combined Figure 2 and Figure 4 As an optional embodiment, the magnetic force F is an attractive force, and the sealing ring 3 is located between the first magnetic member 41 and the second magnetic member 42 along the first direction X. In this way, when the card tray 2 is inserted, the first magnetic member 41 and the second magnetic member 42 are close to each other along the first direction X. When the attractive force reaches the effective range, the attractive force causes the second magnetic member 42 to squeeze the sealing ring 3 along the insertion direction of the card tray 2.

[0052] Furthermore, the first magnetic component 41 and the second magnetic component 42 are both magnets and are installed with opposite poles; in this way, the magnetic force F generated between the first magnetic component 41 and the second magnetic component 42 is stronger, and the force acting on the strap is stronger, the effect of squeezing the sealing ring 3 is better, and a better waterproof effect is achieved.

[0053] As an optional embodiment, one of the first magnetic member 41 and the second magnetic member 42 is a magnet, and the other is an adsorbable ferromagnetic material. In this way, not only can one magnet be saved, reducing costs, but also attraction can still be generated to drive the second magnetic member 42 to move along the first direction X to squeeze the sealing ring 3 to achieve a waterproof effect.

[0054] It is understandable that in both cases, the magnetic force F can be an attractive force. When the card tray 2 is inserted, the first magnetic component 41 attracts the second magnetic component 42 to move along the insertion direction of the card tray 2, thereby squeezing the sealing ring 3 to achieve a waterproof effect.

[0055] Combination Figure 2 and Figure 5 As an optional implementation, the magnetic force F is a repulsive force, and the first magnetic member 41, the second magnetic member 42 and the sealing ring 3 are arranged in sequence along the first direction X. In this way, when the card tray 2 is inserted, the first magnetic member 41 and the second magnetic member 42 are close to each other along the first direction X, and when the repulsive force reaches the range of action, the repulsive force causes the second magnetic member 42 to squeeze the sealing ring 3 along the ejection direction of the card tray 2.

[0056] Furthermore, the first magnetic member 41 and the second magnetic member 42 are both magnets, and the same poles are installed opposite to each other. In this way, the same polarity installation of the magnets generates a repulsive force, and when the card tray 2 is inserted, the first magnetic member repels the second magnetic member 42, and squeezes the sealing ring 3 in the ejection direction of the card tray 2 to achieve a waterproof effect.

[0057] Combination Figures 3 to 7 , Figure 7 for Figure 6 A partial enlarged view of the B in the middle. A limit retaining wall 12 is provided in the card slot 11, and the limit retaining wall 12 is arranged around the inner wall of the slot of the card slot 11. The limit retaining wall 12 is used to limit the position of the card tray 2 inserted into the card slot 11. In this way, damage to the device or performance degradation caused by improper insertion is avoided, and this positioning structure improves the stability and durability of the device.

[0058] It should be noted that the width of the limiting retaining wall 12 in the first direction X should be set as small as possible while being sufficient to support the insertion of the tray 2, so as to minimize the impact on the magnetic force F and ensure that the magnetic force F is strong enough to squeeze the sealing ring 3.

[0059] Combination Figure 3 and Figure 7 In some embodiments, a waterproof retaining wall 13 is provided inside the limiting retaining wall 12. The waterproof retaining wall 13 is arranged around the inner wall of the limiting retaining wall 12. The waterproof retaining wall 13 is arranged at the notch of the limiting retaining wall 12 away from the card slot 11. When the card tray 2 is inserted, the magnetic force F squeezes the sealing ring 3 to prevent moisture from entering, but a small amount of moisture may still enter the inside of the electronic device 100 after passing through the sealing ring 3. Since the sealing ring 3 is located on the notch side of the limiting retaining wall 12 close to the card slot 11, the waterproof retaining wall 13 is arranged at the notch of the limiting retaining wall 12 away from the card slot 11. The height of the waterproof retaining wall 13 in the direction perpendicular to the plane where the card tray 2 is inserted is higher than that of the limiting retaining wall 12, but the height cannot be too high, and it is still necessary to ensure that the main body of the card tray 2 can be smoothly inserted into the card slot 11. In this way, when a small amount of moisture still enters after being sealed by the sealing ring 3, the waterproof retaining wall 13 can further prevent moisture from entering, forming double protection, achieving a better waterproof effect, and improving the reliability of the electronic device 100 in a humid or watery environment.

[0060] Combination Figure 7As an optional implementation, a first notch 13a is provided on one side of the waterproof retaining wall 13 away from the notch of the card slot 11. The first notch 13a is used to install the first magnetic component 41, which can effectively limit the installation position of the first magnetic component 41 and prevent the first magnetic component 41 from moving due to loose fixation under the action of the magnetic force F.

[0061] See also Figure 2 and Figure 8 , Figure 8 The schematic diagram of the structure of the card holder disclosed in the embodiment of the present application is shown in FIG. The card holder 2 is provided with a mounting groove 21. When the card holder 2 is inserted, the mounting groove 21 is located on the side of the notch of the waterproof retaining wall 13 close to the card slot 11. The sealing ring 3 is installed in the mounting groove 21. The side wall of the mounting groove 21 is provided with a second notch 21a, and the second notch 21a is used to install the second magnetic member 42.

[0062] In this way, the setting of the first notch 13a limits the installation position of the first magnetic member 41, preventing the first magnetic member 41 from being loosely fixed and shifting. The mounting groove 21 is used to install the sealing ring 3. When the sealing ring 3 is squeezed by the second magnetic member 42 under the action of the magnetic force F, the sealing ring 3 is deformed but still remains in the original position, effectively preventing the sealing ring 3 from shifting. The setting of the second notch 21a limits the position of the second magnetic member 42, so that when the second magnetic member 42 is acted upon by the magnetic force F, the second magnetic member 42 only moves in the first direction X and squeezes the sealing ring 3, thereby preventing the second magnetic member 42 from shifting during the squeezing process.

[0063] It should be noted that the magnetic force F is an attractive force, and the second notch 21a is provided on the side wall of the mounting groove 21 close to the notch. When the card tray 2 is inserted, the second magnetic member 42 squeezes the sealing ring 3 along the insertion direction of the card tray 2 under the action of the attractive force.

[0064] Optionally, the magnetic force F is a repulsive force, and the second notch 21a is arranged on the side wall of the installation slot 21 away from the slot opening. When the card tray 2 is inserted, the second magnetic member 42 squeezes the sealing ring 3 along the ejection direction of the card tray 2 under the action of the repulsive force.

[0065] Combination Figures 3 to 8 As an optional embodiment, there are multiple first magnetic members 41 and multiple second magnetic members 42, multiple first magnetic members 41 are evenly spaced around the inner wall of the waterproof retaining wall 13, multiple second magnetic members 42 are evenly spaced around the side wall of the installation groove 21, and each first magnetic member 41 and each second magnetic member 42 are correspondingly arranged along the first direction X. The arrangement of multiple magnetic members can generate multiple magnetic forces F along the first direction X to fully squeeze the sealing ring 3, so that the sealing ring 3 is evenly stressed and the waterproof effect is better.

[0066] As an optional embodiment, the sealing ring 3 is a hollow structure. In this way, the weight of the sealing ring 3 and the overall device is reduced, and the material cost is reduced. Moreover, under the action of the magnetic force F, the second magnetic member 42 squeezes the sealing ring 3, so that the air inside the sealing ring 3 flows, so that the sealing ring 3 can fill the gap between the card tray 2 and the card slot 11, making the gap between the card tray 2 and the card slot 11 as small as possible, thereby achieving a better waterproof effect.

[0067] Optionally, the sealing ring 3 is made of deformable materials such as silicone, rubber or polytetrafluoroethylene. These materials can effectively fill the gap by extrusion deformation. The silicone sealing ring 3 has good high temperature resistance and weather resistance, and is suitable for sealing requirements in high temperature environments; the rubber sealing ring 3 has good elasticity and sealing performance; the polytetrafluoroethylene sealing ring 3 has excellent chemical corrosion resistance and high temperature resistance, and is suitable for sealing requirements of high temperature, high pressure and strong corrosive media, which is not limited in this embodiment.

[0068] It should be noted that the electronic device 100 can be a smart phone, tablet, computer, smart watch and other devices. The magnetic part squeezes the sealing ring 3 to better prevent moisture from penetrating between the card tray 2 and the housing 1, and the sealing ring 3 between the card tray 2 and the card slot 11 is interference fit, and the gap between the card tray 2 and the card slot 11 is sealed to achieve a better waterproof effect. The magnetic force F acts to squeeze the sealing ring 3, which can maintain a strong force to achieve a higher sealing of the electronic device 100. The magnetic part has strong adaptability and can adapt to different working conditions, including high and low temperatures and different pressure ranges, which improves the safety and stability of operation.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
