[0002] In today's digital age, various electronic devices have become widely integrated into people's daily lives and work. From smartphones, tablets, and laptops to remote controls, game controllers, and electronic instrument control panels, buttons, as key components of human-computer interaction, play a crucial role. Their development is closely linked to the evolution of electronic devices and continuously adapts to users' demands for ease of operation, reliability, comfort, and diverse functions. Existing button designs are relatively simple, mostly employing mechanical structures.

[0003] However, existing buttons have the following shortcomings in practical use: due to the complexity of their internal mechanical structure and the large number of parts, friction and wear between mechanical components, as well as the complex assembly process, the stability and reliability of mechanical buttons are challenged. Under prolonged and intensive use, buttons are prone to failure due to severe wear. In view of this, the magnetic button of this application is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a magnetic button that reduces friction between components to reduce wear and tear and thus prevent malfunctions.

The first magnetic element is coaxially disposed on the bottom shell, and the second magnetic element is coaxially disposed on the face shell. The magnetic poles of the first magnetic element and the second magnetic element are the same on their adjacent sides. A conductive sheet is disposed on the pressing post. A spherical cavity is formed on the end of the pressing post away from the conductive sheet. A convex spherical post is disposed on the face shell, and the convex spherical post engages with the spherical cavity. When the face shell is subjected to an external force and moves downward, the pressing post causes the conductive sheet to abut against the circuit board to close the circuit, and the second magnetic element moves closer to the first magnetic element. The second magnetic element pushes the first magnetic element away, so that the pressing post causes the conductive sheet to move away from the circuit board to disconnect the circuit.

[0009] Optionally, both the first magnetic element and the second magnetic element are circular ring structures.

[0010] Optionally, both the first magnetic element and the second magnetic element are axially magnetized structures.

[0011] Optionally, the bottom shell has a through hole, and the pressure column passes through the through hole. The diameter of the through hole is smaller than the inner diameter of the first magnetic component and the second magnetic component.

[0012] Optionally, the pressure column is provided with two locking platforms, which are located at both ends of the pressure column, and the two locking platforms alternately abut against the opposite sides of the bottom shell. The spherical chamber is coaxially opened at one end of one of the locking platforms of the pressure column.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] The magnetic button of this invention has a first and a second annular magnetic element on both the bottom shell and the top shell. The two magnetic elements have the same magnetism on the side that is close to each other. When the top shell moves the second magnetic element closer to the first magnetic element, the first magnetic element will push the second magnetic element away so that the top shell is away from the bottom shell. In this way, the friction between the components is reduced, thereby reducing the failure of the button due to wear of the components. Attached Figure Description

[0033] As shown in the figure, in one embodiment, a magnetic button 1 includes a conductive sheet 10 for contacting a circuit board to close or open the circuit, a bottom shell 20, and a pressing assembly 30. The pressing assembly 30 includes a pressing post 31, a front shell 32, a first magnetic element 33, and a second magnetic element 34. The pressing post 31 is coaxially disposed on the bottom shell 20, the first magnetic element 33 is coaxially disposed on the bottom shell 20, and the second magnetic element 34 is coaxially disposed on the front shell 32, with the first magnetic element 33 and the second magnetic element 34 located close to each other. The magnetic poles of the surfaces are the same. The conductive sheet 10 is disposed on the pressure post 31. A spherical cavity 311 is opened on the end of the pressure post 31 away from the conductive sheet 10. A convex spherical post 321 is disposed on the surface shell 32. The convex spherical post 321 is engaged with the spherical cavity 311. When the surface shell 32 is subjected to external force, it moves downward, causing the pressure post 31 to drive the conductive sheet 10 to abut against the circuit board to close the circuit. It also causes the second magnetic element 34 to approach the first magnetic element 33. The second magnetic element 34 pushes the first magnetic element 33 away, so that the pressure post 31 drives the conductive sheet 10 away from the circuit board to disconnect the circuit.

[0034] It should be noted that both the first magnetic component 33 and the second magnetic component 34 are magnet structures, and both are annular structures. The inner diameter of the first magnetic component 33 is smaller than the inner diameter of the second magnetic component 34. Furthermore, a through hole 21 is formed on the inner bottom wall of the bottom shell 20, and the pressure post 31 is coaxially inserted through the through hole 21, with both ends of the pressure post 31 extending from the two sides of the bottom shell 20. Furthermore, a circular groove 25 is formed in the bottom shell 20 with the axis of the through hole 21 as the center. The inner diameter of the circular groove 25 is larger than the diameter of the through hole 21. The first magnetic component 33 is disposed within the circular groove 25, making its inner diameter also larger than the diameter of the through hole 21. Furthermore, since the pressure post 31 is coaxially inserted through the through hole 21, it is positioned relative to the first magnetic component 33. Furthermore, a frustum 322 is provided on the face shell 32. The diameter of the frustum 322 is larger than that of the through hole 21, and a groove 3221 is provided on the frustum 322. The inner diameter of the groove 3221 is larger than that of the pressure post 31, so that one end of the pressure post 31 is located in the groove 3221. Furthermore, an annular groove 3222 is provided on the outer wall of the frustum 322, and the second magnetic element 34 is disposed in the annular groove 3222. Thus, when the face shell 32 is subjected to external force and approaches the bottom shell 20, the convex spherical column 321 on the face shell 32 is engaged with the spherical cavity 311 on the pressure column 31, causing the face shell 32 to drive the pressure column 31 to extend from one end of the bottom shell 20. At the same time, the face shell 32 drives the second magnetic element 34 to approach the first magnetic element 33. Since the magnetic poles of the sides of the first magnetic element 33 and the second magnetic element 34 that are close to each other are the same, according to the principle that like poles of magnets repel and unlike poles attract, the first magnetic element 33 pushes the second magnetic element 34 away, thereby causing the face shell 32 to drive the pressure column 31 to extend from the inner bottom wall of the bottom shell 20. Furthermore, the conductive sheet 10 is positioned on the end of the pressure post 31 furthest from the faceplate 32. This allows the pressure post 31 to bring the conductive sheet 10 into contact with the circuit board when the faceplate 32 is subjected to external force and approaches the bottom shell 20, thus closing the circuit. Simultaneously, it also brings the second magnetic component 34 closer to the first magnetic component 33. Once the second magnetic component 34 is close to the first magnetic component 33, the first magnetic component 33 pushes the second magnetic component 34, moving the faceplate 32 away from the bottom shell 20. This causes the pressure post 31 to move the conductive sheet 10 away from the circuit board, thus opening the circuit. This reduces friction between components, preventing button malfunctions under prolonged, high-intensity use.

[0035] It should be noted that the faceplate 32 is also provided with a convex spherical post 321, the end of the convex spherical post 321 away from the faceplate 32 is spherical. Furthermore, the end of the pressure post 31 near the faceplate 32 is provided with a spherical cavity 311. The opening of the spherical cavity 311 tends to be conical, while the inside of the spherical cavity 311 is spherical. The size of the spherical cavity 311 is interference-fitted with the size of the convex spherical post 321. In this way, the faceplate 32 can tilt relative to the pressure post 31 without a fixed direction. Thus, no matter what external force the faceplate 32 is subjected to, it can drive the pressure post 31 to slide coaxially with respect to the through hole 21 on the bottom shell 20, thereby making the conductive sheet 10 on the pressure post 31 smoothly abut against the circuit board.

[0036] It should be noted that both the first magnetic element 33 and the second magnetic element 34 are axially magnetized. Both are magnetized along their central axis, for example, with one end face as the north pole and the other as the south pole. In this magnetization method, magnetic lines of force emanate from one end face of the ring, pass axially through the interior of the ring, and then enter from the other end face, forming a closed loop of magnetic lines of force. Thus, when the second magnetic element 34 approaches the first magnetic element 33, since the end faces of the first and second magnetic elements 33 and 34 have the same magnetic pole, the first magnetic element 33 can push the second magnetic element 34 away, thereby causing the outer shell 32 to move away from the bottom shell 20.

[0037] As shown in the figure, in one embodiment, the pressure column 31 is provided with two locking platforms, which are located at both ends of the pressure column 31 respectively, and the two locking platforms alternately abut against the opposite sides of the bottom shell 20. The ball chamber 311 is coaxially opened at one end of one of the locking platforms of the pressure column 31.

[0038] It should be noted that each end of the pressure column 31 is provided with a locking platform, both of which are circular ring structures. For ease of description, the two locking platforms are defined as the first locking platform 312 and the second locking platform 313. The first locking platform 312 is located on the end of the pressure column 31 closest to the face shell 32, and the second locking platform 313 is located on the end of the pressure column 31 furthest from the face shell 32. The first locking platform 312 abuts against the inner bottom wall of the bottom shell 20, and the second locking platform 313 abuts against the outer surface of the bottom shell 20. For example, when the face shell 32 causes the pressure column 31 to extend from the outer surface of the bottom shell 20, the first locking platform 312 will abut against the inner bottom wall of the bottom shell 20 to prevent the pressure column 31 from completely detaching from the bottom shell 20. When the face shell 32 causes the pressure column 31 to extend from the inner bottom wall of the bottom shell 20, the second locking platform 313 will abut against the outer surface of the bottom shell 20 to prevent the face shell 32 and the pressure column 31 from completely falling off the bottom shell 20.

[0039] As shown in the figure, in one embodiment, the pressing component 30 further includes a third magnetic element 35, which is disposed on the pressing column 31, and the pressing column 31 drives the third magnetic element 35 to approach the first magnetic element 33. The magnetic poles of the side of the third magnetic element 35 and the first magnetic element 33 that are close to each other are the same.

[0040] It should be noted that the inner diameter of the third magnetic component 35 is larger than the diameter of the pressure post 31, allowing the third magnetic component 35 to be fitted onto the pressure post 31. The outer diameter of the third magnetic component 35 is the same as the outer diameter of the mounting platform, ensuring a complete fit between the third magnetic component 35 and the mounting platform when fitted onto the pressure post 31. Furthermore, the third magnetic component 35 is fitted onto the pressure post 31 and fits against the first mounting platform 312, with the third magnetic component 35 located on the side of the first mounting platform 312 facing the first magnetic component 33. When the pressure post 31 slides relative to the bottom shell 20, the pressure post 31, through the first mounting platform 312, causes the third magnetic component 35 to also slide relative to the bottom shell 20, thereby causing the third magnetic component 35 to slide closer to or further away from the first magnetic component 33.

[0041] As shown in the figure, in one embodiment, the magnetic poles of the third magnetic element 35 and the first magnetic element 33 are the same on the side that are close to each other.

[0042] It should be noted that the third magnetic component 35 has the same structure as the first magnetic component 33 and the second magnetic component 34, and is also a circular axial magnetic ring magnet. Each of the two end faces of the third magnetic component 35 has a magnetic pole. When the pressure post 31 drives the third magnetic component 35 closer to the first magnetic component 33 through the first locking platform 312, the first magnetic component 33 can push the third magnetic component 35 away, so that the third magnetic component 35 drives the pressure post 31 to extend out from the inner bottom wall of the bottom shell 20.

[0043] As shown in the figure, in one embodiment, a groove 3221 is provided on the face shell 32. The inner diameter of the groove 3221 is larger than the diameter of the pressure column 31, and the convex spherical column 321 is coaxially disposed on the inner bottom wall of the circular groove 25.

[0044] It should be noted that a frustum 322 is provided on the face shell 32. The diameter of the frustum 322 is larger than that of the through hole 21. A groove 3221 is provided on the frustum 322. The inner diameter of the groove 3221 is larger than that of the pressure post 31. Thus, one end of the pressure post 31 is located in the groove 3221. An annular groove 3222 is provided on the outer wall of the frustum 322. The second magnetic component 34 is disposed in the annular groove 3222.

[0045] It should be noted that the outer diameter of the first card platform 312 is larger than that of the pressure post 31, and the inner diameter of the groove 3221 is larger than that of the first card platform 312, so that the first card platform 312 can be located within the groove 3221, and there is a gap between the inner sidewall of the first card platform 312 and the groove 3221. Furthermore, since both the first card platform 312 and the groove 3221 are circular structures, the gap between the first card platform 312 and the inner sidewall of the groove 3221 is an annular structure. When the face shell 32 can tilt and swing around the spherical cavity 311, there is sufficient clearance between the inner sidewall of the groove 3221 and the first card platform 312. At the same time, the face shell 32 will also drive any end of the frustum 322 to approach the first magnetic component 33. Furthermore, since one end of the convex ball post 321 and the ball cavity 311 are both spherical structures, the tilted face shell 32 can also drive the pressure post 31 to slide relative to the axis of the bottom shell 20. In this way, the button can be pressed by the user's finger from different directions in actual use, thereby improving the user's comfort. Furthermore, since the third magnetic element 35 is disposed on the outer wall of the frustum 322, when the face shell 32 is tilted relative to the spherical cavity 311, since both the third magnetic element 35 and the first magnetic element 33 are annular structures, when the face shell 32 drives any one radial end of the third magnetic element 35 to approach the first magnetic element 33, the other radial end of the third magnetic element 35 will move away from the first magnetic element 33. This causes the radial surfaces of the third magnetic element 35 and the first magnetic element 33 to rotate around the spherical cavity 311 so that there is an angle between the two radial surfaces. As the like poles of the magnets repel each other, the first magnetic element 33 pushes against the end of the third magnetic element 35 that is approaching, thereby keeping the radial surfaces of the third magnetic element 35 and the first magnetic element 33 parallel. Both the third magnetic element 35 and the first magnetic element 33 are circular ring structures. Thus, when the face shell 32 moves any end of the third magnetic element 35 close to the first magnetic element 33, the first magnetic element 33 will push the third magnetic element 35, so that the third magnetic element 35 moves the face shell 32 to remain parallel to the first magnetic element 33 with the spherical cavity 311 as the center. This allows the face shell 32 to move the pressure column 31 vertically or at an inclined angle, and the first magnetic element 33 can restore the face shell 32 to a parallel state.

[0046] As shown in the figure, in one embodiment, the ball chamber 311 is located on the end of the first locking platform 312 on the pressure column 31, and the convex ball column 321 is disposed on the inner bottom wall of the groove 3221. When the first locking platform 312 is located in the groove 3221, the convex ball column 321 can be engaged with the ball chamber 311.

[0047] It should be noted that the spherical chamber 311 includes a spherical groove 3111 and a conical hole 3112. The conical hole 3112 has a conical structure. The end of the conical hole 3112 with the smallest diameter is connected to the spherical groove 3111, and the end of the conical hole 3112 with the largest diameter is connected to the end face of the pressure post 31 near the face shell 32. Further, the convex spherical post 321 includes a sphere 3211 and a post 3212. The sphere 3211 is disposed on one end of the post 3212, and the end of the post 3212 away from the sphere 3211 is connected to the inner bottom wall of the groove 3221. It should be noted that the diameter of the sphere 3211 is smaller than the diameter of the spherical groove 3111, allowing the sphere 3211 to be located within the spherical groove 3111. Furthermore, the diameter of the sphere 3211 is larger than the minimum diameter of the conical hole 3112, ensuring that the minimum diameter of the conical hole 3112 can hold the sphere 3211 in place after it is inserted into the spherical groove 3111, thus preventing the sphere 3211 from detaching from the spherical groove 3111. Furthermore, the diameter of the cylinder 3212 is smaller than the minimum diameter of the conical hole 3112. Thus, when the sphere 3211 rotates in any direction relative to the spherical groove 3111, the sphere 3211 causes the cylinder 3212 to swing in any direction within the conical hole 3112, thereby allowing the faceplate 32 to tilt in any direction relative to the pressure column 31. Furthermore, the end face of the pressure column 31 near the face shell 32 is an arc-shaped structure, so that when the face shell 32 is tilted relative to the pressure column 31, the circular periphery of the end face of the pressure column 31 near the face shell 32 can avoid the inner bottom wall of the hole groove 3221, so that the face shell 32 can tilt better.

[0048] As shown in the figure, in one embodiment, the face shell 32 has a square structure, and the end face of the bottom shell 20 away from the through hole 21 has a square structure. Limiting parts are provided around the face shell 32. When the convex ball post 321 on the face shell 32 is engaged with the ball cavity 311, the limiting parts around the face shell 32 together cover the end face of the bottom shell 20 away from the through hole 21. In this way, water flows into the interior of the bottom shell 20 from the side during use. Furthermore, the bottom shell 20 is also provided with several buckles. Each buckle is distributed at intervals along the circumference of the circular groove 25, and each buckle together clamps the first magnetic element 33.

[0049] As shown in the figure, in one embodiment, the pressing component 30 further includes a buffer pad 22, which is disposed on the bottom shell 20 and is located between the circular groove 25 and the through hole 21.

[0050] It should be noted that a buffer pad 22 is provided on the bottom shell 20, which is located between the circular groove 25 and the through hole 21. A top ring 23 is also provided on the bottom shell 20, which is located between the through hole 21 and the circular groove 25. For example, the inner diameter of the top ring 23 is the same as the diameter of the through hole 21, and the outer diameter of the top ring 23 is the same as the outer diameter of the circular groove 25. This makes the distance between the circular groove 25 and the through hole 21 form a raised annular structure, so that when the first card platform 312 drives the third magnetic component 35 to approach the first magnetic component 33, the third magnetic component 35 and the first magnetic component 33 can still maintain a distance at one end, avoiding the third magnetic component 35 from being damaged by direct collision with the first magnetic component 33. Furthermore, the buffer pad 22 is located on the side of the top ring 23 facing the first card platform 312. In this way, when the first card platform 312 moves the third magnetic component 35 close to the first magnetic component 33, the buffer pad 22 can reduce the sound generated by the collision between the third magnetic component 35 and the top ring 23, thereby improving the quietness of the button.

[0051] As shown in the figure, in one embodiment, the bottom shell 20 is provided with a drainage hole 24.

[0052] It should be noted that the drain hole 24 penetrates the two opposing sides of the bottom shell 20, allowing water that has entered the bottom shell 20 to be discharged from the bottom shell 20.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
