Description

Technical Field

[0001] This utility model relates to the technical field of switches, specifically to a switch button. Background Technology

[0002] Traditional buttons use elastic components such as springs and sheet metal to provide rebound force for button reset. After a certain number of presses, the elastic material will become weak, age, or experience metal fatigue, leading to rebound failure. Utility Model Content

[0003] Based on the above description, this utility model provides a switch button to solve the problem that traditional buttons use elastic components such as springs and sheet springs to provide rebound force for button reset. After a certain number of presses, the elastic material will become weak, age, or experience metal fatigue, leading to rebound failure.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] This application provides a switch button, and the technical solution adopted is as follows:

[0006] A switch button includes a base and a keycap mounted on the base. The keycap is movable relative to the base along a first straight direction between a first position and a second position that are spaced apart. A first magnet and a second magnet are respectively provided on the base and the keycap. When the keycap moves from the first position to the second position, it overcomes the repulsive force between the first magnet and the second magnet. The position of the second magnet relative to the keycap in the first straight direction is adjustable.

[0007] Preferably, the base includes a cylindrical mounting portion, with a first straight direction parallel to the axis of the mounting portion. The keycap is cylindrical with one end closed and the other end open. The open end of the keycap is coaxially sleeved outside the mounting portion. The keycap can move axially relative to the mounting portion and is restricted to move relative to the mounting portion in a direction perpendicular to its own axis. When the keycap moves from the first position to the second position, the closed end moves closer to the mounting portion.

[0008] Preferably, the first magnet is disposed inside the mounting portion, and the second magnet is disposed inside the keycap and its position is adjustable along the axial direction of the keycap.

[0009] Preferably, the keycap has a threaded post coaxially connected to it, and an adjusting block threadedly connected to it is provided on the outer ring of the threaded post. The second magnet is connected to the adjusting block and embedded in the mounting part. The keycap is cylindrical and can rotate relative to the mounting part around its own axis. The second magnet is restricted by the mounting part to rotate with the keycap.

[0010] Preferably, the second magnet is in the shape of a rectangular ring and is arranged around the threaded post. The inner cross-section of the mounting part is rectangular and adapted to the second magnet. When the second magnet is embedded in the mounting part, it is restricted from rotating with the keycap relative to the mounting part.

[0011] Preferably, the keycap includes an operating section and a connecting section in the axial direction. The operating section is close to the closed end, the connecting section is sleeved outside the mounting part, and the inner diameter of the operating section is smaller than the outer diameter of the mounting part. When the keycap moves to the second position, the end face of the operating section abuts against the end face of the mounting part.

[0012] Preferably, the base is connected to a housing, the housing is cylindrical and coaxially sleeved on the keycap, and a limiting ring is connected to one end of the housing near the closed end of the keycap, which is encircled outside the operating section. The inner diameter of the limiting ring is smaller than the outer diameter of the connecting section. When the keycap moves to the first position, the end face of the connecting section abuts against the limiting ring.

[0013] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects:

[0014] 1. This application utilizes the repulsive force between the first and second magnets as the force for keycap reset. The design incorporates a single switching action as the keycap moves from the first position to the second position. The magnetic force does not weaken or disappear with the number of keycap movements (switching actions), thus preventing keycap failure due to rebound issues. Furthermore, the adjustable position of the second magnet relative to the keycap in the first linear direction allows for adjustments to the user's tactile feedback. This adjusts the distance between the first and second magnets when the keycap moves to the second position, thereby regulating the repulsive force and satisfying the user's tactile requirements. Additionally, even if the magnetic force of the first and second magnets weakens due to other factors (such as high or low temperatures, oxidation, or corrosion), adjusting the position of the second magnet relative to the keycap ensures sufficient repulsive force for keycap reset, thus extending keycap lifespan.

It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0024] Reference Figure 1-2 As shown, this application embodiment provides a switch button, which includes a base 1 and a keycap 2 mounted on the base 1. The keycap 2 can move relative to the base 1 along a first straight direction between a first position and a second position that are spaced apart. A first magnet 3 and a second magnet 4 are respectively provided on the base 1 and the keycap 2. When the keycap 2 moves from the first position to the second position, it overcomes the repulsive force between the first magnet 3 and the second magnet 4. The position of the second magnet 4 relative to the keycap 2 in the first straight direction is adjustable.

[0025] Reference Figure 1-2 As shown, the base 1 includes a cylindrical mounting portion 11, with a first linear direction parallel to the axis of the mounting portion 11. The keycap 2 is cylindrical, with one end closed and the other open. The open end of the keycap 2 is coaxially sleeved outside the mounting portion 11. The keycap 2 can move axially relative to the mounting portion 11 and is restricted to moving relative to the mounting portion 11 in a direction perpendicular to its own axis. When the keycap 2 moves from the first position to the second position, the closed end moves closer to the mounting portion 11. Correspondingly, the first linear direction is the axial direction of the keycap, while the second position is closer to the keycap.

[0026] Reference Figure 1-2 As shown, the keycap 2 includes an operating section 21 and a connecting section 22 in the axial direction. The operating section 21 is close to the closed end, and the connecting section 22 is sleeved on the outside of the mounting part 11. The inner diameter of the operating section 21 is smaller than the outer diameter of the mounting part 11. When the keycap 2 moves to the second position, the end face of the operating section 21 abuts against the end face of the mounting part 11. A housing 5 is also connected to the base 1. The housing 5 is cylindrical and coaxially sleeved on the outside of the keycap 2. A limiting ring 51 is connected to the end of the housing 5 near the closed end of the keycap 2, which is encircled by the operating section 21. The inner diameter of the limiting ring 51 is smaller than the outer diameter of the connecting section 22. When the keycap 2 moves to the first position, the end face of the connecting section 22 abuts against the limiting ring 51.

[0027] Reference Figure 1-2As shown, specifically, the base 1 includes a base plate 12 and a mounting part 11. The axis of the mounting part 11 is perpendicular to the base plate 12 and one end is connected to the base plate 12. The mounting part 11 and the base plate 12 are integrally formed. The keycap 2 is sleeved on the end of the mounting part 11 away from the base plate 12. The keycap 2 is an integrally formed structure. Steps are formed on both the outer and inner walls of the keycap 2 between the operating section 21 and the connecting section 22. This allows the keycap 2 to move to the second position, where the stepped surface of the operating section 21 (i.e., the inner wall) abuts against the end face of the mounting part 11. When the keycap 2 moves to the first position, the stepped surface of the connecting section 22 (i.e., the outer wall) abuts against the limiting ring 51. This achieves a stable connection between the keycap 2 and the base 1, allowing the keycap 2 to move between the first and second positions without detaching. In this embodiment, the base plate 12 is a circular plate coaxial with the mounting part 11, the outer shell 5 is cylindrical and coaxially sleeved on the outside of the base plate 12, and the inner wall of the outer shell 5 and the peripheral side wall of the base plate 12 are provided with mutually compatible threads so that the outer shell 5 and the base plate 12 are threadedly connected; the limiting ring 51 is integrally formed with the outer shell 5.

[0028] Reference Figure 1-2 As shown, further, the first magnet 3 is disposed inside the mounting portion 11, and the second magnet 4 is disposed inside the keycap 2 and its position in the axial direction of the keycap 2 is adjustable. Specifically, the keycap 2 has a threaded post 6 coaxially connected to it, and an adjusting block 7 threadedly connected to it is provided around the outer ring of the threaded post 6. The second magnet 4 is connected to the adjusting block 7 and embedded inside the mounting portion 11. The keycap 2 is cylindrical and can rotate relative to the mounting portion 11 around its own axis, and the second magnet 4 is restricted by the mounting portion 11 to rotate with the keycap 2. In this embodiment, the second magnet 4 is rectangular and is arranged around the threaded post 6. The cross-section of the inner hole of the mounting portion 11 is rectangular and adapted to the second magnet 4. When the second magnet 4 is embedded inside the mounting portion 11, it is restricted to rotate with the keycap 2 relative to the mounting portion 11.

[0029] With this configuration, when the keycap 2 is rotated, the threaded post 6 rotates with the keycap 2, but the second magnet 4 does not rotate with the threaded post 6 under the limiting action of the mounting part 11. This allows the second magnet 4 to move relative to the threaded post 6 along the axial direction of the threaded post 6, thereby adjusting the position of the second magnet 4 relative to the keycap 2 in the axial direction of the threaded post 6, i.e., the axial direction of the keycap 2. On the one hand, according to the user's tactile feedback requirements, the position of the second magnet 4 relative to the keycap 2 can be adjusted to regulate the distance between the first magnet 3 and the second magnet 4 when the keycap 2 moves to the second position, thereby adjusting the magnitude of the repulsive force experienced by the keycap 2 when it moves to the second position to meet the user's tactile feedback requirements. On the other hand, even if the magnetic force of the first magnet 3 and the second magnet 4 weakens due to other reasons (such as high and low temperatures, oxidation and corrosion, etc.), the repulsive force between the second magnet 4 and the first magnet 3 can be adjusted to be sufficient to reset the keycap 2 by adjusting the position of the second magnet 4 relative to the keycap 2, thereby improving the service life of the key.

[0030] Reference Figure 1-2As shown, a mounting hole 121 for mounting the spring contact of the switch is further provided on the base plate 12. The mounting hole 121 is coaxially arranged with the mounting part 11. The threaded post 6 and the keycap 2 are integrally formed by conductors and serve as another contact of the switch. In the design, when the keycap 2 is moved to the second position, the threaded post 6 contacts the spring contact installed in the mounting hole 121.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
