[0027] In addition, the terms "mount", "set", "provided with", "connected", "connected to" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral structure; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, or there may be internal communication between two devices, elements or components.

[0029] In the field of application of electronic devices, waterproof design is regarded as a crucial step. From outdoor adventure equipment to deep-sea exploration instruments, to military equipment in harsh environments and consumer electronics for daily use, strict standards are imposed on the waterproof performance of electronic devices, aiming to resist moisture penetration, protect the delicate electronic components inside the electronic devices from damage, and maintain the continuous and stable operation of the devices. Effective waterproof design can not only significantly extend the service life of electronic devices, but also ensure the safety and reliability of electronic devices in extreme climates or harsh environments, reducing the risk of failures caused by moisture intrusion into the electronic devices.
[0030] However, external buttons need to be set on the electronic device to connect or conduct with the internal electronic components. Since the buttons usually need to pass through the housing of the electronic device, it results in imperfect button structures and the existence of potential gaps. These defects are extremely likely to become channels for moisture intrusion, thereby triggering serious consequences such as oxidation and corrosion of electronic components, short circuits in the circuit, and may even exacerbate hardware damage due to phenomena such as electrostatic discharge, affecting the overall performance and service life of the electronic device.
[0031] To solve the above problems, the inventor studied the button structure of the electronic device, improved the existing electronic device, and designed a button structure that can achieve button functions without opening through holes in the middle frame.
[0032] Based on this, the embodiments of the present application disclose an electronic device, which can avoid opening through holes in the middle frame, avoid the generation of gaps between the buttons and the middle frame, and ensure the waterproof and dustproof performance of the electronic device.
[0033] The technical solutions of the present application will be further described below in conjunction with the embodiments and the drawings.
[0034] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 which is one of the three-dimensional structure diagrams of the electronic device 01 provided by the embodiments of the present application, Figure 2 which is the second three-dimensional structure diagram of the electronic device 01 provided by the embodiments of the present application, Figure 3 For Figure 2Schematic cross-sectional view of the electronic device 01 along the A-A direction. An embodiment of the present application discloses an electronic device 01, including: a middle frame 10, on the outer side of the middle frame 10, there is a chute 101 extending along the first direction X; a first magnetic member 102, slidably arranged in the chute 101 and capable of sliding in the chute 101 along the first direction X; a second magnetic member 103, arranged on the inner side of the middle frame 10, the second magnetic member 103 is magnetically coupled with the first magnetic member 102, and the second magnetic member 103 can slide relative to the middle frame 10 along with the first magnetic member 102; a first feeding point 201, located inside the middle frame 10, the first feeding point 201 can slide relative to the middle frame 10 along with the second magnetic member 103 along the first direction X; a second feeding point 202, arranged inside the middle frame 10 and fixed relative to the middle frame 10, the first feeding point 201 can approach or move away from the second feeding point 202 when sliding along the first direction X.
[0035] It can be understood that the electronic device 01 can be a device such as a smart phone, a tablet, a computer, a smart watch, etc. The electronic device 01 usually has a length direction, a width direction, and a thickness direction. The length direction is the extension direction of the long side of the electronic device 01, and the width direction is the extension direction of the short side of the electronic device 01. For the convenience of description, as Figure 1 shown, in the embodiment of the present application, the length direction of the electronic device 01 is referred to as the first direction X, and the thickness direction of the electronic device 01 is referred to as the second direction Y.
[0036] Exemplarily, the second direction Y can intersect with the first direction X. In some examples, the second direction Y can be perpendicular or approximately perpendicular to the first direction X. It can be understood that the second direction Y can be "approximately perpendicular" to the first direction X, that is, the included angle between the second direction Y and the first direction X can be approximately equal to 90°, such as 88°, 89°, 91°, or 92°, etc. The middle frame 10 is the main structure of the electronic device 01. The middle frame 10 is usually used to carry components such as the display screen of the electronic device 01, connect the bottom cover of the electronic device 01, and at the same time isolate the electronic components inside the electronic device 01 from the external environment. The middle frame 10 is usually made of durable materials such as metal or high-strength plastic, and can protect the components inside the electronic device 01 from external impacts.
[0037] For the convenience of user operation, the buttons of the electronic device 01 are arranged on the middle frame 10. Exemplarily, on the outer side of the middle frame 10, there is a chute 101 extending along the first direction X, and the chute 101 does not penetrate the middle frame 10 to avoid punching holes in the middle frame 10 and maintain the integrity and sealing of the middle frame 10.
[0038] The slide groove 101 has a containing space, which is used to accommodate the first magnetic member 102 and allows the first magnetic member 102 to slide inside the slide groove 101. The slide groove 101 provides a sliding path and a positioning reference for the first magnetic member 102, ensuring that the first magnetic member 102 slides along the predetermined first direction X, thereby avoiding the first magnetic member 102 from being offset or misaligned during the sliding process, preventing the first magnetic member 102 from being deviated from the predetermined path due to external force, or generating unnecessary shaking or noise due to the looseness of internal components, thereby ensuring the stability and reliability of the sliding of the first magnetic member 102.
[0039] Optionally, the inner wall of the slide groove 101 may be provided with a limiting rib or one of the limiting ribs extending along the first direction X, and the surface of the first magnetic member 102 in contact with the inside of the slide groove 101 may be provided with a limiting rib or the other of the limiting ribs, and a limiting fit is formed between the limiting rib and the limiting groove along the thickness direction of the electronic device 01 to limit the direction in which the first magnetic member 102 escapes from the slide groove 101, so as to prevent the first magnetic member 102 from escaping from the slide groove 101. In addition, the sliding fit between the limiting groove and the fiber rib further ensures the smoothness of the first magnetic member 102 sliding in the slide groove 101.
[0040] The contact surface between the slide groove 101 and the first magnetic member 102 can be polished and smoothed by fine machining to minimize the friction and resistance generated during the sliding process of the first magnetic member 102 relative to the slide groove 101, which helps to achieve smooth sliding of the first magnetic member 102, reduces the inconvenience of user operation caused by the first magnetic member 102 sliding jam or blockage caused by friction, ensures the rapid response of user commands, and improves the response speed and operation smoothness of the device. At the same time, the friction and resistance between the slide groove 101 and the first magnetic member 102 are reduced, which reduces the wear between the slide groove 101 and the first magnetic member 102 and extends the service life of the key.
[0041] The second magnetic member 103 is disposed inside the middle frame 10, and the second magnetic member 103 and the first magnetic member 102 are disposed in correspondence with each other with the middle frame 10 being separated, and the first magnetic member 102 and the second magnetic member 103 are magnetically matched. When the first magnetic member 102 is subjected to an external force applied by a user to slide the first magnetic member 102, the first magnetic member 102 can slide in the slide groove 101 along the first direction X, and the magnetic force of the first magnetic member 102 magnetically adsorbing the second magnetic member 103 can drive the second magnetic member 103 to move synchronously with the first magnetic member 102 along the first direction X extending from the slide groove 101.
[0042] The contact surface between the middle frame 10 and the second magnetic member 103 can also be polished smoothly through precision machining to minimize the friction and resistance generated during the sliding of the second magnetic member 103 relative to the middle frame 10, which helps to achieve smooth sliding of the second magnetic member 103, reduces the inconvenience of user operation caused by the jamming or blocking of the second magnetic member 103 during sliding due to friction, ensures the rapid response of user instructions, and improves the response speed and operation fluency of the device. At the same time, the reduction of friction and resistance between the middle frame 10 and the second magnetic member 103 reduces the wear between the middle frame 10 and the second magnetic member 103 and extends the service life of the key.
[0043] Optionally, the first magnetic member 102 and the second magnetic member 103 can be made of any one of neodymium iron boron magnets, permanent magnets, and ferrite magnets. The first magnetic member 102 and the second magnetic member 103 are both magnets and are installed with opposite poles facing each other, and this installation method has a relatively stable adsorption. Or one of the first magnetic member 102 and the second magnetic member 103 is made of a magnetic material, and the other is made of a ferromagnetic substance that can be adsorbed, such as materials that can be adsorbed by magnetic members like iron, cobalt, nickel, and their alloys, etc., to reduce costs. The present embodiment does not limit the material selection of the first magnetic member 102 and the second magnetic member 103.
[0044] The first feeding point 201 is located inside the middle frame 10, and the first feeding point 201 can slide along the first direction X relative to the middle frame 10 following the second magnetic member 103. The second feeding point 202 is arranged inside the middle frame 10 and is fixed relative to the middle frame 10. The design that the first feeding point 201 is slidable and the second feeding point 202 is fixed enables the first feeding point 201 to approach or move away from the second feeding point 202 along the first direction X, thereby being able to change the distance between the first feeding point 201 and the second feeding point 202.
[0045] The second feeding point 202 is connected to the signal transmission line inside the electronic device 01. After the first feeding point 201 contacts the second feeding point 202, the circuit is connected and can be recognized by the circuit inside the electronic device 01 as a signal indicating that the key is activated, thereby triggering corresponding functions or operations. After the first feeding point 201 is separated from the second feeding point 202, the circuit is disconnected, and it will also be recognized by the circuit inside the electronic device 01 to stop the current function, turn off a certain device, or enter the standby mode, thereby realizing the switch function of the key.
[0046] In this way, the electronic device 01 can install and use the key without opening through holes on the middle frame 10, avoiding the entry of water into the electronic device 01 caused by the loose fit and gaps between the through holes on the middle frame 10 and the key, preventing the oxidation and corrosion of electronic components inside the electronic device 01, circuit short - circuit, etc., improving the service life of the electronic device 01, and also ensuring the safety and reliability of the electronic device 01 in extreme climates or harsh environments.
[0047] Please refer to Figure 2 As an alternative embodiment, the second feeding point 202 is located on the moving path of the first feeding point 201.
[0048] The second feeding point 202 is fixed relative to the middle frame 10, providing a target position for the movement of the first feeding point 201. The second feeding point 202 is arranged on the moving path of the first feeding point 201. In this way, when the first feeding point 201 moves, it can make contact with or separate from the second feeding point 202, so as to convert the contact or separation between the first feeding point 201 and the second feeding point 202 into an electrical signal and transmit it to the electronic device 01, realizing the switch function of the button.
[0049] Furthermore, please refer to Figure 2 , the electronic device 01 further includes: a slider 30, which is fixedly connected to the second magnetic member 103 inside the middle frame 10, and the first feeding point 201 is arranged on the slider 30.
[0050] The fixed connection between the slider 30 and the second magnetic member 103 ensures that the slider 30 can stably slide synchronously with the second magnetic member 103. The first feeding point 201 is arranged on the slider 30, thus ensuring the accuracy of the moving position of the first feeding point 201. The change in the distance between the first feeding point 201 and the second feeding point 202 can be controlled more precisely, which helps to realize more refined function adjustment in the electronic device 01.
[0051] Optionally, the material of the slider 30 can be conductive materials such as brass, aluminum alloy, steel, etc. The slider 30 can be electrically connected to other electronic components. The first feeding point 201 is electrically connected to the slider 30, so as to transmit the electrical signal generated by the first feeding point 201 to the electronic device 01. This embodiment does not make any limitation on this.
[0052] Please refer to Figure 3 , as an alternative embodiment, the electronic device 01 further includes: an installation groove 301 is arranged on one side of the slider 30 facing the middle frame 10, and the second magnetic member 103 is arranged in the installation groove 301.
[0053] The installation groove 301 provides structural support for the second magnetic member 103, which helps to reduce the shaking or offset generated between the second magnetic member 103 and the slider 30 during the sliding process, thereby improving the stability of the sliding process of the slider 30.
[0054] Optionally, a magnetic isolation layer can be arranged between the slider 30 and the second magnetic member 103 to ensure that the interaction between the second magnetic member 103 on the first feeding point 201 and other electronic components connected to the second feeding point 202 will not cause electromagnetic interference or affect the normal operation of the device.
[0055] Such as Figure 2As shown, further, the second magnetic member 103 is bonded to the inner wall of the mounting groove 301 through the bonding layer 302 .
[0056] The adhesive layer 302 can firmly fix the second magnetic member 103 on the inner wall of the mounting groove 301 , thereby reducing the risk of loosening between the second magnetic member 103 and the slider 30 or the slider 30 falling off due to vibration or impact.
[0057] Compared with mechanical fixing methods (such as screws, buckles, etc.), the adhesive layer 302 can disperse mechanical stress and reduce potential damage to the second magnetic member 103 and the mounting groove 301. It also avoids the influence of the metal component fixing method on the electrical signal transmitted on the slider 30, ensuring that the electrical signal transmitted between the first feeding point 201 and the second feeding point 202 is stable and reliable. In addition, the adhesive fixing method does not require additional fasteners or tools, which helps to reduce assembly costs and improve production efficiency.
[0058] Optionally, the adhesive layer 302 may be made of materials such as epoxy resin adhesive, polyurethane adhesive, and thermal conductive adhesive, which is not limited in this embodiment. Before bonding, the inner wall of the mounting groove 301 and the surface of the second magnetic member 103 need to be properly processed (e.g., cleaned, degreased, roughened, etc.) to improve the bonding effect.
[0059] See also Figure 2 As an optional implementation, the electronic device 01 also includes: a guide rail 40, which is arranged inside the middle frame 10, the second feeding point 202 is arranged on the guide rail 40, the slider 30 is slidably connected to the guide rail 40, the guide rail 40 is a metal guide rail 40, and the slider 30 is a metal slider 30.
[0060] The guide rail 40 is disposed inside the middle frame 10 and extends along the first direction X, and the slider 30 is slidably connected to the guide rail 40. The guide rail 40 provides a stable support for the slider 30, and can bear the weight of the slider 30 and the force generated when sliding, thereby ensuring the stability of the sliding fit between the slider 30 and the guide rail 40. At the same time, the guide rail 40 provides a fixed moving path for the slider 30, ensuring that the slider 30 maintains a predetermined track during the sliding process, thereby reducing deviation and shaking.
[0061] The second feeding point 202 is disposed on the guide rail 40 . The second feeding point 202 can maintain a relatively stable position during the sliding process of the slider 30 , thereby ensuring stable transmission of signals between the first feeding point 201 and the second feeding point 202 .
[0062] The guide rail 40 or the slider 30 can be made of metal, which is a good conductor to ensure that the guide rail 40 and the slider 30 can effectively transmit current or signals. The material of the guide rail 40 can be brass, aluminum alloy, carbon steel and other conductive materials, which is not limited in this embodiment.
[0063] The second magnetic member 103 moves synchronously under the adsorption of the first magnetic member 102, thereby driving the slider 30 to slide along the first direction X. In this process, the distance between the first feed point 201 on the slider 30 and the second feed point 202 fixed on the guide rail 40 will change dynamically as the slider 30 slides relative to the guide rail 40. At this time, the guide rail 40 can be regarded as a resistor. Based on the basic principle of resistance calculation, that is, the resistance value of a conductor with equal cross-section is linearly positively correlated with its length, the change in the distance between the first feed point 201 and the second feed point 202 leads to a change in the resistance value between the first feed point 201 and the second feed point 202. Therefore, by reading the resistance value between the first feed point 201 and the second feed point 202, the current position state of the first feed point 201 and the second feed point 202 can be determined, thereby realizing the physical interaction between the button and the electronic device 01.
[0064] This method of changing the resistance by changing the distance between the first feeding point 201 and the second feeding point 202 can make the resistance value change continuously and smoothly within the entire length of the guide rail 40 to achieve the purpose of stepless adjustment, and can replace the existing volume key, brightness key, etc. The user can continuously adjust parameters such as volume, screen brightness, etc. by continuously and smoothly moving the first magnetic member 102 without being limited to the preset fixed gear. This adjustment method not only provides higher flexibility and precision, but also improves the user experience. Please refer to Figure 2 As an optional implementation, the second feed point 202 is located at the end of the guide rail 40. The second feed point 202 is located at the end of the guide rail 40 to extend the moving space of the first feed point 201 relative to the second feed point 202, thereby expanding the working range of the key and increasing the range of functions that the key can control.
[0065] As an optional implementation, the guide rail 40 extends along the first direction X, and any cross-sectional area of the guide rail 40 along the second direction Y is equal.
[0066] The area of the guide rail 40 is equal on any cross section along the second direction Y. No matter which cross section of the second direction Y is measured, the cross-sectional area of the guide rail 40 is the same, thereby ensuring that the resistance of the guide rail 40 does not differ due to the change of its cross section, which helps to more accurately calculate the distance and resistance value between the first feeding point 201 and the second feeding point 202, and ensures the stability and uniformity of the guide rail 40 when subjected to force.
[0067] See also Figure 3 As an optional implementation, a mounting hole 303 is provided on the slider 30, and the slider 30 is sleeved on the guide rail 40 through the mounting hole 303. The slider 30 can slide back and forth along the first direction X relative to the guide rail 40.
[0068] The slider 30 is provided with a mounting hole 303. The shape and size of the mounting hole 303 match the cross-section of the guide rail 40 to ensure that the guide rail 40 can smoothly pass through the mounting hole 303 and maintain a stable position inside the slider 30. This mating design helps reduce friction and wear during the sliding process. The mounting hole 303 allows the slider 30 to be sleeved on the guide rail 40 through the mounting hole 303, enabling the guide rail 40 to pass through the mounting hole 303 and remain inside the slider 30, and the slider 30 can reciprocally slide relative to the guide rail 40 along the first direction X.
[0069] Furthermore, the mounting hole 303 on the slider 30 closely mates with the cross-section of the guide rail 40, ensuring the stability and precision of the slider 30 on the guide rail 40. This mating method can reduce errors caused by looseness or misalignment, improving the reliability and stability of the system.
[0070] Please refer to Figure 3 , as an alternative embodiment, the cross-section of the guide rail 40 along the second direction Y is polygonal, and the shape of the mounting hole 303 is adapted to the guide rail 40.
[0071] Compared with circular or other-shaped guide rails 40, the polygonal guide rail 40 provides better stability in multiple directions. The polygonal cross-section of the guide rail 40 helps prevent the slider 30 from shifting or rotating during the sliding process. The shape of the mounting hole 303 needs to match the cross-section of the guide rail 40, that is, the mounting hole 303 is also a polygonal hole, and the number of sides and side lengths correspond to the cross-section of the guide rail 40 to ensure that the slider 30 can be closely sleeved on the guide rail 40.
[0072] To ensure that the slider 30 can smoothly slide on the guide rail 40, the mating clearance between the mounting hole 303 and the guide rail 40 needs to be controlled within a reasonable range. An overly tight fit will increase the sliding resistance, while an overly loose fit may cause the slider 30 to wobble during the sliding process. To improve the friction performance and wear resistance between the mounting hole 303 and the guide rail 40, the surfaces of the mounting hole 303 and the guide rail 40 can be appropriately treated to reduce friction.
[0073] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
