Description

Technical Field

[0001] This utility model relates to the field of keyboard button technology, specifically to a magnetic button. Background Technology

[0002] With the continuous advancement of electronic device control technology, in addition to traditional mechanical switches, technologies utilizing light and magnetic sensing have gradually been applied. For example, in the field of mechanical keyboards, since the 1980s, various product types have emerged, including mechanical conductive keyboards (around 1984), light conductive keyboards (around 2014), and magnetic conductive keyboards (around 2019). Magnetic conductive keyboards (also known as magnetic keyboards or magnetic axis keyboards) are favored by users for their faster response speed and more stable input quality. Magnetic conductive keyboards utilize the magnetic elements of the magnetic keys and corresponding magnetic sensors to achieve opening and closing sensing. When a key is not pressed, the magnetic element and the magnetic sensor maintain a certain distance. When a key is pressed, the magnetic element moves closer to the magnetic sensor as the key is pressed down. The magnetic sensor senses the change in the magnetic field and generates a corresponding sensing output.

[0003] While existing magnetic keys meet usage needs to some extent, they have the following significant drawbacks: during operation, users may unintentionally shake the keys, causing the magnetic components to move uncontrollably, resulting in unstable and inaccurate sensing signals. In the field of mechanical keyboards, trigger accuracy and stability are important considerations.

[0004] Industry professionals have also improved the button mechanism of magnetic buttons to enhance trigger stability and user experience. For example, Reference 1 achieved a linear feel for the magnetic button, Reference 2 added a bottom-sealing structure to improve stability during travel and bottoming out, and took into account the feel and sound feedback during operation. Reference 3 placed the magnetic element on an independent moving part outside the magnetic core, intending to reduce the interference of shaking on the magnetic element during operation.

[0007] Reference 3: CN118431006A Utility Model Content

[0008] On one hand, this application proposes a magnetic button, comprising: a base, the inner surface of which is provided with a guide ring; a top cover, which is connected to the base to form an accommodating space, the top cover having a through hole; a shaft core, the upper part of which can slide out of the through hole, the bottom of which is provided with a snap-fit ​​connector; a guide post, which can move up and down along the guide ring, the bottom of which is provided with a magnetic element mounting groove; the top of which is provided with an outwardly extending flange; and a snap-fit ​​groove that can engage with the snap-fit ​​connector. When the shaft core is subjected to a horizontal force, the shaft core can move relative to the guide post in the horizontal direction; a magnetic element, which is installed in the magnetic element mounting groove; and an elastic element, which is disposed within the accommodating space, the upper end of which abuts against the flange, and the lower end of which abuts against the inner surface of the base. This application features a detachable connection between the shaft and guide post, allowing them to move independently within a certain range, forming a buffer gap. This ensures the magnetic element maintains horizontal stability and guarantees that the guide post only shifts under vertical pressure, improving signal conversion stability and sensing accuracy. It also reduces the impact of unintentional shaft movement on the magnetic element. This solves the problem of reduced trigger stability due to shaft movement during magnetic button operation, and retains the magnetic element on the guide post, ensuring no reduction in trigger accuracy. Compared to existing solutions, this design is simpler, increases production efficiency, and significantly reduces manufacturing difficulty and cost. The structure, materials, and models of the base, top cover, elastic element, and magnetic element, the fit and installation relationships between components, and how the shaft moves reciprocally within the accommodating space to enable the magnetic button to cooperate with the magnetic sensor on the keyboard PCB for opening and closing are all well-known technologies in the field and will not be elaborated upon here.

[0009] Furthermore, the first slot is connected to the first magnetic element mounting slot. This facilitates the manufacture and installation of the magnetic element. Of course, in some designs, the first slot and the first magnetic element mounting slot may not be directly connected.

[0010] Furthermore, the slot one includes an upper slot and a lower slot, with the cross-section of the lower slot being larger than that of the upper slot. This facilitates the manufacturing and installation of magnetic components. Of course, the slot one can also be configured in other forms without a clear upper and lower slot separation; for example, it can be configured as a slot that is narrower at the top and wider at the bottom.

[0011] Furthermore, the guide post, the shaft, and the magnetic element are arranged coaxially, which facilitates manufacturing and installation, improves the sensing effect of the magnetic element, and makes the installation accuracy easier to control. Of course, in some solutions, different axis arrangements of the above components can also be achieved.

[0012] Furthermore, the magnetic element and the magnetic element mounting groove are interference-fitted, which facilitates manufacturing and installation. In addition, other conventional installation or fitting methods can also be selected, such as bonding.

[0013] Furthermore, there is an movable gap between the card connector and the card slot.

[0014] Furthermore, the upper groove, the lower groove, and the magnetic element mounting groove are coaxially arranged, which facilitates manufacturing and installation, improves the sensing effect of the magnetic element, and makes the installation accuracy easier to control. Of course, in some solutions, the above components can also be arranged with different axes.

[0015] Furthermore, the snap-fit ​​connector has two or more snap hooks, which are connected to the bottom surface of the shaft core. There is a gap between the snap hooks. Normal installation and assembly can be achieved even if there is only one snap hook. Usually, the force-bearing structure is more even with two or more snap hooks.

[0016] Furthermore, the snap connector and the shaft core are an integral structure, for example, it can be an integrally injection molded structure.

[0017] Furthermore, there are two or three hooks arranged symmetrically along the axis. The structure of two or three hooks is convenient for manufacturing and installation. Of course, the hooks can also be arranged asymmetrically.

[0018] Furthermore, the latch includes a connecting post and a latch head. The top end of the connecting post is fixedly connected to the bottom surface of the shaft core, and the lower end of the connecting post is fixedly connected to the latch head. The placement of the connecting post and latch head to achieve latching is a conventional method, and the shapes of the connecting post and latch head generally do not require special limitation.

[0019] Furthermore, the lower side of the hook head is provided with a lower guide slope, which is a slope that slopes inward from top to bottom. The slope can be a relatively flat surface or a surface with a certain curvature. The slope is provided to facilitate manufacturing and installation, and it is also possible to achieve the desired result without a significant slope.

[0020] Furthermore, the upper side of the hook head is also provided with an upper guide slope. The upper guide slope is a slope that slopes outward from top to bottom. The slope can be a relatively flat surface or a surface with a certain curvature. The slope is provided to facilitate manufacturing, installation, and disassembly. It is also possible to achieve the same result without a significant slope.

[0021] Furthermore, there is a movable gap between the hook head and the lower groove, and a movable gap between the connecting post and the upper groove.

[0022] Furthermore, the elastic element is sleeved on the outside of the guide ring.

[0023] Furthermore, the magnetic element is a magnet, and the elastic element is a spring.

[0024] Furthermore, the base has a boss inside, the guide ring is arranged around the outside of the boss, and the bottom of the base also has pins.

[0025] Furthermore, the number of pins is two and they are distributed symmetrically or asymmetrically.

[0026] Furthermore, the elastic element, the magnetic element, and the guide ring are all annular, which facilitates manufacturing and installation; other shapes can also be achieved.

[0027] This application connects the integrally formed shaft and guide post in the existing structure in a detachable manner, allowing them to move independently within a certain range and forming a buffer gap. This ensures that the magnetic element maintains horizontal stability and guarantees that the guide post only shifts when pressed vertically, improving signal conversion stability and sensing accuracy. It also reduces the impact of shaft shaking on the magnetic element during unintentional operation. This solves the problem of shaft shaking reducing trigger stability during magnetic button operation and allows the magnetic element to remain on the guide post, ensuring that the trigger accuracy of the magnetic element is not reduced. Compared with existing solutions, this application has a simpler structure, improved production efficiency, and significantly reduced manufacturing difficulty and cost.

The top of the second guide post is provided with a magnetic element mounting groove. The magnetic element is installed in the magnetic element mounting groove. The connecting plate is connected to the second guide post. The connecting plate is provided with a snap-fit ​​groove that can engage with the snap-fit ​​connector. When the shaft core is subjected to a horizontal force, the shaft core can move horizontally relative to the connecting plate and the second guide post. The elastic element is provided in the accommodating space. The upper end of the elastic element abuts against the connecting plate. The lower end of the elastic element abuts against the inner surface of the base. Compared to the magnetic button provided in the first aspect, this solution features a dedicated connecting plate. The design of the connecting plate allows the magnetic element to be installed inside the guide post, keeping the magnetic element on the guide post and making the guide post structure closer to a mechanically conductive button. Compared to the existing technology where the magnetic element is installed from the bottom to the guide post, this solution closes the bottom of the guide post, allowing the magnetic button to reproduce the tactile and sound effects of various traditional mechanical shafts. Furthermore, it offers higher production efficiency and significantly reduces manufacturing difficulty and cost.

[0030] Furthermore, the cross-section of the second slot is smaller than the cross-section of the second magnetic element mounting slot.

The snap-fit ​​is located at the top of the second guide post, and the connecting plate has a snap-fit ​​groove at the corresponding position of the snap-fit. The snap-fit ​​and snap-fit ​​groove here can adopt a conventional snap-fit ​​structure. The snap-fit ​​groove can be entirely opened inside the connecting plate, or it can be partially connected to the edge opening of the connecting plate, as long as it can cooperate with the snap-fit ​​to achieve the snap-fit ​​connection.

[0036] Furthermore, the upper end of the elastic element abuts against the bottom edge of the connecting plate.

[0041] Furthermore, the snap connector and the shaft core are an integral structure.

[0042] Furthermore, the hooks are two or three in number and are arranged symmetrically or asymmetrically along an axis.

[0043] Furthermore, the hook includes a connecting post and a hook head, with the top end of the connecting post fixedly connected to the bottom surface of the shaft core, and the lower end of the connecting post fixedly connected to the hook head.

[0044] Furthermore, the lower side of the hook head is provided with a lower guide slope, which is an inward slope from top to bottom.

[0045] Furthermore, the upper side of the hook head is also provided with an upper guide slope, which is a slope that slopes outward from top to bottom.

[0046] Furthermore, there is a movable gap between the connecting post and the second slot, and there is a movable gap between the hook head and the second slot.

[0047] Furthermore, the second slot includes an upper slot and a lower slot, the cross-section of the lower slot is larger than the cross-section of the upper slot, there is a movable gap between the connecting post and the upper slot, and there is a movable gap between the hook head and the lower slot.

[0048] Furthermore, a clearance hole is provided on the lower side of the second slot, there is an movable gap between the connecting post and the second slot, and there is an movable gap between the hook head and the clearance hole.

[0081] Example 1

[0082] This embodiment describes a magnetic button. Please refer to... Figure 1 As shown, it includes: a base 400, with a guide ring 410 on the inner surface of the base 400; a top cover 300, which is connected to the base 400 to form an accommodating space, the top cover 300 having a through hole 310; a shaft 100, the upper part of which can slide out of the through hole 310, the bottom of which has a snap-fit ​​connector 110; a guide post 200a, which can move up and down along the guide ring 410, the bottom of which has a magnetic element mounting groove, and the top of which has a... An outer flange 210 extends outwards. The guide post 200a is provided with a slot 220a that can engage with the snap-fit ​​connector 110. When the shaft core 100 is subjected to a horizontal force, the shaft core 100 can move relative to the guide post 200a in the horizontal direction. A magnetic element 230 is installed in the magnetic element mounting slot. An elastic element 500 is provided in the accommodating space. The upper end of the elastic element 500 abuts against the flange 210, and the lower end of the elastic element 500 abuts against the inner surface of the base 400.

[0083] The technical advantages of this embodiment are as follows: In existing solutions (such as references 1-3), the shaft core and guide post are designed as an integral part or fixedly connected. This application connects the shaft core and guide post in a detachable manner, allowing them to move independently within a certain range, forming a buffer gap. This ensures that the magnetic element maintains horizontal stability and guarantees that the magnetic element in the guide post only shifts when pressed vertically. This improves signal conversion stability and sensing accuracy, and reduces the impact of shaft core shaking on the magnetic element during unintentional operation. It solves the problem of shaft core shaking reducing trigger stability during magnetic button operation, and allows the magnetic element to remain on the guide post, ensuring that the trigger accuracy of the magnetic element is not reduced. Compared with existing solutions (such as reference 3), the implementation structure is simpler, production efficiency is improved, and manufacturing difficulty and cost are significantly reduced.

[0084] Example 2

[0085] Based on Embodiment 1, this embodiment discloses further designs for the magnetic button's shaft, guide post, and base. Please refer to... Figure 2 Furthermore, the card slot 220a is connected to the magnetic element mounting slot.

[0086] Furthermore, the card slot 220a includes an upper slot 2210a and a lower slot 2220a, and the cross-section of the lower slot 2220a is larger than the cross-section of the upper slot 2210a.

[0087] Furthermore, the guide post 200a, the shaft core 100, and the magnetic element 230 are arranged coaxially or on different axes.

[0088] Furthermore, the guide post 200a, shaft core 100, and magnetic element 230 are in the shape of a ring or rectangle, etc.

[0089] Furthermore, the guide post 200a, the shaft core 100, and the magnetic element 230 are in the shape of a ring.

[0090] Furthermore, there is an movable gap between the card connector 110 and the card slot 220a.

[0091] Furthermore, the upper groove 2210a, the lower groove 2220a, and the magnetic element mounting groove are arranged coaxially or non-coaxially.

[0092] Furthermore, the magnetic element 230 and the magnetic element mounting groove are interference-fitted.

[0093] Please refer to Figure 3 As shown, furthermore, the outer surface of the guide post 200a includes protrusions 270, and the inner wall of the guide ring 410 is provided with grooves 4110. The protrusions 270 engage with the grooves 4110, so that the guide post 200a can only move up and down along the straight line defined by the grooves 4110. This prevents the guide post 200a from being affected by the left and right rotation, offset, or shaking of the shaft core 100, thus keeping the magnetic element 230 stable and further improving the stability of the magnetic button. It can also reduce the friction between the guide post and the guide ring to a certain extent, making the button feel smoother. There is at least one protrusion 270 to cooperate with at least one groove. The number of protrusions 270 can be set to be the same as the number of grooves 4110, or the number of protrusions 270 can be less than the number of grooves 4110.

[0094] The outer surface of the protrusion 270 slopes inward from top to bottom. This effectively reduces the shaking of the shaft core 100 when it touches the bottom.

[0095] Please refer to Figure 4 Furthermore, the elastic element 500 is sleeved on the outside of the guide ring 410.

[0096] Furthermore, the base 400 is provided with a boss 420, the guide ring 410 is arranged around the outside of the boss 420, and the bottom of the base 400 is also provided with a pin 430.

[0097] Furthermore, the number of pins 430 is two, and they are either symmetrically or asymmetrically distributed.

[0098] Furthermore, the elastic element 500, the magnetic element 230, and the guide ring 410 are all annular.

[0099] Furthermore, the magnetic element 230 is a magnet, and the elastic element 500 is a spring.

[0100] The technical effects of this embodiment are as follows: This application, through the movable gap between the card connector and the card slot, can ensure that the guide post is not affected when the shaft moves horizontally; through a simple and easy-to-manufacture structure, it successfully solves the problem of unstable and inaccurate signal caused by the shaft shaking due to different pressing positions.

[0101] Example 3

[0102] Based on Embodiment 1, this embodiment discloses a further design of the card connector.

[0103] Please refer to Figure 9 As shown, the snap-fit ​​connector 110 further has two or more snap hooks, which are connected to the bottom surface of the shaft core 100, and there is a gap between the snap hooks.

[0104] Furthermore, the snap connector 110 and the shaft core 100 are an integral structure.

[0105] Furthermore, the hooks are two or three in number and are arranged symmetrically or asymmetrically along an axis.

[0106] Furthermore, the hook includes a connecting post 1110 and a hook head 1120. The top end of the connecting post 1110 is fixedly connected to the bottom surface of the shaft core 100, and the lower end of the connecting post 1110 is fixedly connected to the hook head 1120.

[0107] Furthermore, there is a movable gap between the hook head 1120 and the lower groove 2220a, and there is a movable gap between the connecting post 1110 and the upper groove 2210a.

[0108] Furthermore, the lower side of the hook head 1120 is provided with a lower guide slope 1122, which is a slope that slopes inward from top to bottom.

[0109] Furthermore, the upper side of the hook head 1120 is also provided with an upper guide slope 1121, which is a slope that slopes outward from top to bottom.

[0110] The technical effects of this embodiment are as follows: The hook head structure described in this application can quickly connect the shaft core and the guide post or connecting plate through the lower guide slope, and can quickly disassemble and assemble through the upper guide slope. The design of the snap-fit ​​connector makes the whole structure more flexible.

Inside the magnetic component mounting slot 2, there is a connecting plate 240, which is connected to the guide post 200b. The connecting plate 240 is provided with a slot 220b that can engage with the snap-fit ​​connector 110. When the shaft core 100 is subjected to a horizontal force, the shaft core 100 can move horizontally relative to the connecting plate 240 and the guide post 200b. An elastic element 500 is provided in the accommodating space. The upper end of the elastic element 500 abuts against the connecting plate 240, and the lower end of the elastic element 500 abuts against the inner surface of the base 400.

[0114] The technical effects of this embodiment are as follows: By designing a connecting plate, this application installs magnetic components inside the guide post. While retaining the magnetic components on the guide post, the structure of the guide post is made closer to that of a mechanically conductive button. This allows the magnetic button to reproduce the tactile and sound effects of various traditional mechanical shafts. Furthermore, it increases production efficiency, significantly reduces manufacturing difficulty and cost, and to a certain extent reduces the possibility of magnetic components being contaminated.
