Description

Technical Field

[0001] This invention relates to the technical field of computer input devices, and more particularly to a high-performance magnetic axis keyboard. Background Technology

[0002] A keyboard is an input device that converts data into a form that a computer can process. With the development of technology, the technical content of keyboards has been increasing. For example, a magnetic axis keyboard is a type of keyboard that uses changes in magnetic fields to trigger key signals. Its core principle is to use a Hall effect sensor to detect the displacement of the magnet inside the axis and convert the key action into an electrical signal. Compared with traditional mechanical axes, magnetic axes do not require physical contact and have the characteristics of contactless triggering, adjustable trigger point, and high response speed.

[0003] For example, Chinese utility model patent with announcement number CN221529155U discloses a keyboard that can replace the magnetic axis with a mechanical axis. The magnetic axis keyboard shown mainly achieves the triggering effect by sensing each other between the magnetic axis body and the Hall module.

[0004] However, current magnetic switch keyboards still have many shortcomings. Due to the limitations of their architecture, most magnetic switch keyboards rely on springs for linear key press and rebound, resulting in a limited range of tactile feedback. For example, they struggle to meet the diverse needs of different users for varying key pressure levels. Furthermore, with prolonged use, the springs experience mechanical fatigue, leading to changes in key pressure and tactile feedback, and potentially affecting the keyboard's sensitivity. Currently, there is a lack of high-performance magnetic switch keyboards that allow for adjustable key pressure; therefore, improvements to existing technology are necessary.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Summary of the Invention

[0009] The outer casing is connected to the keyboard body;

[0010] A shaft core is vertically mounted inside the housing, and the shaft core is equipped with a magnet.

[0011] A Hall sensor is disposed in the housing and engages with the magnet in a sensing manner;

[0012] Floating components are mounted on the housing and raised or lowered.

[0013] Springs are connected to both the shaft and the floating element.

[0014] An adjusting element is disposed in the housing and connected to the floating element. The adjusting element is used to drive the floating element to rise and fall to adjust the spring's initial compression.

[0015] Preferably, the adjusting element includes:

[0016] A knob is rotatably disposed on the housing, and the bottom of the housing has a first clearance hole for exposing the knob;

[0018] Preferably, the bottom of the outer casing is provided with a mounting groove that communicates with the first clearance hole, and the knob is slidably mounted in the mounting groove;

[0019] The adjusting element also includes a limiting cover plate, which has a second clearance hole in the middle for the threaded connecting shaft to pass through. The limiting cover plate is movably fastened to the outer shell. When the limiting cover plate is fastened to the outer shell, the limiting cover plate blocks the mounting groove and prevents the knob from loosening.

[0020] Preferably, the outer periphery of the knob is provided with a passing point protrusion, and the groove wall of the mounting groove is provided with a plurality of passing point grooves that are movably engaged with the passing point protrusion. The passing point protrusion and the passing point grooves are used to make the knob produce a passing point feel when rotated.

[0021] Preferably, the bottom of the knob is provided with a positioning post, and the keyboard body is provided with a positioning hole, and the positioning post is inserted into the positioning hole;

[0022] The end of the positioning post has a straight groove or a cross groove.

[0023] Preferably, the floating element includes:

[0024] The first cylinder is connected to the adjusting element;

[0025] And an annular boss is provided at one end of the first cylinder and located on the outer periphery, the annular boss is slidably connected to the outer shell, and one end of the spring is sleeved on the first cylinder and abuts against the annular boss.

[0026] Preferably, the annular boss has outwardly protruding guide protrusions on opposite sides, and the inner walls of opposite sides of the outer shell have guide grooves, with the two guide protrusions slidingly engaged in the two guide grooves respectively.

[0027] Preferably, the shaft core is provided with a second cylinder, the first cylinder and the second cylinder are sleeved together, the other end of the spring is sleeved on the second cylinder, and the first cylinder and the second cylinder slide against each other.

[0028] Preferably, the housing has a central axis, the shaft, the floating element, the spring, and the adjusting element are all located on the central axis, and the magnet and the Hall sensor are offset to the outside of the central axis.

[0029] Preferred options also include:

[0030] A pressure sensor is disposed between the floating element and the spring and abuts against the spring to acquire a pressure signal;

[0031] The system is connected to the pressure sensor, which sends a pressure signal to the system, and the system obtains the pressure value based on the pressure signal.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The high-performance magnetic axis keyboard provided by this invention can drive a floating element to move up and down within the casing by activating an adjustment element, thereby controlling the length of the spring. This is equivalent to controlling the initial compression of the spring before it generates downward pressure. According to Hooke's Law, the spring force can be adjusted. On the one hand, for different users, the position of the floating element can be controlled to change the amount of actuation force, meeting the usage needs of different user groups. On the other hand, when the spring experiences mechanical fatigue after long-term use, the spring force can be increased by adjusting the position of the floating element, thereby achieving a suitable tactile feel and extending the service life of the magnetic axis. This achieves adjustable actuation force and solves the problem of a single trigger force.

[0053] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0054] In the description of this invention, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present simultaneously. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be an intermediate component present simultaneously.

[0055] Furthermore, terms such as “long,” “short,” “inner,” and “outer” indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the purpose of describing the present invention and are not intended to indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of the present invention.

[0056] The following is in conjunction with the appendix Figure 1-6 The technical solution of the present invention will be further illustrated through specific embodiments.

[0057] Please refer to Figure 1 This invention provides a high-performance magnetic axis keyboard, including a keyboard body 1, a magnetic axis 2, and keycaps 3. The magnetic axis 2 is mounted on the keyboard body 1, and the keycaps 3 are mounted on the magnetic axis 2. The user triggers the magnetic axis 2 by pressing it, thereby generating an electrical signal, which is input to the computer device through the circuit system in the keyboard body 1. The triggering principle of the keyboard will not be described in detail here.

[0058] Reference Figure 2 and Figure 3 To solve the problem of the inability to adjust the pressing force, the magnetic shaft 2 includes a housing 21, a shaft core 22, a Hall sensor 23, a floating element 24, a spring 25, and an adjusting element 26.

[0059] The outer casing 21 provides mounting positions for various components and parts, and is connected to the keyboard body 1. In this embodiment, the magnetic shaft 2 is described in its conventional use state, that is, in its vertical installation state. In this state, the outer casing 21 mainly includes an upper casing 211 and a lower casing 212. The upper casing 211 and the lower casing 212 are fastened together by fasteners, thus fixing them together and forming a cavity inside the outer casing 21. In addition, fasteners are also provided on the outer periphery of the lower casing 212. The lower casing 212 is fastened to the positioning plate of the keyboard body 1 through these fasteners, thereby realizing the installation of the outer casing 21.

[0060] Based on this, the spindle core 22 is raised and lowered within the outer casing 21. Specifically, a through hole 2111 is provided at the top of the outer casing 21, that is, the through hole 2111 extends through the upper casing 211. By inserting the spindle core 22 into the through hole 2111, the spindle core 22 can be raised and lowered under the guidance of the through hole 2111. At the same time, the top of the spindle core 22 has a cross structure for connecting with the keycap 3.

[0061] In addition, the shaft core 22 is provided with a magnet 222. Typically, the magnet 222 is fixedly installed on the shaft core 22, for example, by secondary injection molding or adhesive fixation. Under this setting, the shaft core 22 can drive the magnet 222 to move up and down synchronously when it moves up and down.

[0062] Furthermore, the magnet 222 is mainly used to sense and cooperate with the Hall sensor 23. Specifically, the Hall sensor 23 is located at the lower shell 212 of the outer casing 21 and is positioned opposite the magnet 222. During the lifting and lowering movement of the shaft core 22, the distance between the magnet 222 and the Hall sensor 23 will change back and forth, thereby achieving sensing and cooperation. When the magnet 222 approaches the Hall sensor 23 within a certain distance, the Hall sensor 23 will generate a trigger signal. At this time, the lower shell 212 is also provided with a terminal 4. The Hall sensor 23 is connected to the terminal 4 and then connected to the PCB board on the keyboard body 1 through the terminal 4. The trigger signal generated by the Hall sensor 23 is transmitted to the main control chip on the PCB board through the terminal 4, and is converted into an input signal by the main control chip and sent to the computer device to realize signal input.

[0063] In addition, the floating element 24 is raised and lowered on the housing 21, and the spring 25 is connected to the shaft core 22 and the floating element 24 respectively. The spring 25 uses the floating element 24 as a fulcrum and is used to provide support force for the shaft core 22. When the spring 25 is in the initial state, the spring 25 lifts the shaft core 22. At this time, the button is not triggered. When the button is pressed, the shaft core 22 moves down and squeezes the spring 25 until the button is released. The spring 25 drives the shaft core 22 to return to its original position.

[0064] Furthermore, the adjusting element 26 is disposed in the housing 21 and connected to the floating element 24. The adjusting element 26 is used to drive the floating element 24 to rise and fall to adjust the initial compression of the spring 25.

[0065] Specifically, the adjusting element 26 has two application states for the floating element 24:

[0066] On the one hand, when the adjusting element 26 drives the floating element 24 to rise, it will compress the space between the spring 25 and the shaft core 22, thereby shortening the length of the spring 25 in the initial state, which is equivalent to increasing the initial compression of the spring 25. At this time, when pressing the button, more force is required, the feel will become heavier, better feedback can be obtained, and accidental touches can also be prevented.

[0067] On the other hand, when the adjusting element 26 drives the floating element 24 to move down, it increases the space between the spring 25 and the core 22, thereby increasing the length of the spring 25 in the initial state, which is equivalent to reducing the initial compression of the spring 25. At this time, the force required to press the key is reduced, the feel becomes lighter, which can improve typing speed and comfort, and also reduce fatigue.

[0068] By adopting the above solution, this embodiment provides a high-performance magnetic axis keyboard that can control the pressing force. By operating the adjustment element 26, the initial compression of the spring 25 can be changed, thereby changing the pressing force, which meets the diverse needs of different users for the keyboard pressing force, and also overcomes the long-standing defect of the magnetic axis keyboard having a single feel.

[0069] Reference Figure 4 and Figure 5 To adjust the structural height of the floating element 24, the adjustment element 26 provided in this application embodiment includes a knob 261 and a threaded connecting shaft 262.

[0070] The knob 261 is rotatably mounted on the outer casing 21. Specifically, in this embodiment, the knob 261 is a disc-shaped knob 261, which is horizontally positioned. The bottom of the outer casing 21 has a first clearance hole 2121 for exposing the knob 261. The first clearance hole 2121 is through-hole mounted on the lower casing 212. One end of the threaded connecting shaft 262 is connected to the knob 261, and the other end has an external thread. The threaded connecting shaft 262 is perpendicular to the knob 261. Figure 4 The center is vertically oriented, and the threaded connecting shaft 262 is integrally connected to the knob 261; at the same time, the floating element 24 is provided with a threaded hole, and the threaded connecting shaft 262 is connected to the threaded hole through an external thread.

[0071] Based on the above solution, by rotating the knob 261, the knob 261 will drive the threaded connecting shaft 262 to rotate. With the cooperation of the external thread and the threaded hole, by changing the specific rotation direction of the knob 261, such as rotating in the forward or reverse direction, the floating element 24 can be pushed to move up and down, thereby realizing the height adjustment function. The operation is simple and quick, and the structure is simple, which can also meet the cost requirements.

[0072] Furthermore, continue to refer to Figure 4 and Figure 5 To ensure stable rotation of the knob 261 within the housing 21, the adjusting element 26 further includes a limiting cover plate 263. The bottom of the housing 21 has a mounting groove 6 that communicates with the first clearance hole 2121. Specifically, the mounting groove 6 is recessed from the outside inwards at the inner bottom wall of the lower housing 212, and the opening size and dimensions of the mounting groove 6 are adapted to the outer size and dimensions of the knob 261. In this embodiment, the mounting groove 6 is circular. By placing the knob 261 into the mounting groove 6, the groove wall of the mounting groove 6 can abut against the knob 261, thereby allowing the knob 261 to be slidably mounted within the mounting groove 6.

[0073] Based on this, the limiting cover 263 is located above the knob 261. The limiting cover 263 has a second clearance hole 2631 in the middle for the threaded connecting shaft 262 to pass through, and the limiting cover 263 is movably fastened to the outer shell 21.

[0074] Specifically, there are fasteners (not shown in the figure) inside the outer shell 21 and around the perimeter of the limiting cover 263. The two are elastically engaged by the fasteners to achieve a movable fastening effect. The fasteners are a conventional setting method, and the specific structure of the fasteners will not be described in detail here. Under the action of the fasteners, when the limiting cover 263 is fastened to the outer shell 21, the limiting cover 263 blocks the mounting groove 6 and prevents the knob 261 from loosening.

[0075] Based on the above solution, on the one hand, the mounting groove 6 provides an installation position for the knob 261 and can accommodate the knob 261. The knob 261 can also further improve the compactness of the structure when it is rotated. On the other hand, by setting the limiting cover plate 263, the knob 261 can be vertically limited, so that the knob 261 is more stable during use and is not easy to fall off. Moreover, the installation process of the knob 261 and the limiting cover plate 263 is convenient. You only need to put the knob 261 into the mounting groove 6 and then install the limiting cover plate 263, which is quick and convenient.

[0076] Furthermore, referring to Figure 5The outer periphery of the knob 261 is provided with a passing point protrusion 5, the surface of which is a spherical surface. Meanwhile, the groove wall of the mounting groove 6 is provided with multiple passing point grooves 61 that are movably engaged with the passing point protrusion 5. The passing point grooves 61 have spherical surfaces that are adapted to the shape of the passing point protrusion 5. The passing point protrusion 5 and the passing point grooves 61 are used to make the knob 261 produce a passing point feel when it is rotated.

[0077] In the above scheme, both the knob 261 and the outer shell 21 are made of plastic during the rotation process, so they can be elastically deformed. This allows the protrusions 5 to switch sequentially into different grooves 61. On the one hand, this enables fine gear adjustment, making the force adjustment more precise and achieving fine adjustment. On the other hand, it allows the knob 261 to stay at a specific angle, and it is not easy to rotate or loosen on its own without external force, so the pressing force of the button can be kept constant.

[0078] Furthermore, referring to Figure 4 The bottom of the knob 261 is also provided with a positioning post 2611. The positioning post 2611 is perpendicular to the knob 261 and is located on the side of the knob 261 opposite to the threaded connecting shaft 262; additionally, combined with... Figure 1 The keyboard body 1 is provided with positioning holes 7. Specifically, the positioning holes 7 are located on the PCB board of the keyboard body 1. The positioning post 2611 is inserted and cooperates with the positioning hole 7. With the insertion and cooperation of the two, the magnetic switch 2 can be positioned during installation, and the installation accuracy of the magnetic switch 2 is optimized and improved.

[0079] In addition, the positioning post 2611 on the knob 261 allows the user to apply rotational force to the knob 261, facilitating its rotation. In one embodiment, the outer circumferential surface of the positioning post 2611 can be patterned to increase friction, thereby facilitating the rotation of the positioning post 2611 and consequently rotating the knob 261. In the embodiment provided in this example, the end of the positioning post 2611 has a slotted groove or a Phillips head groove. It can be understood that "one end" refers to the end of the positioning post 2611 away from the knob 261, and the slotted groove or Phillips head groove is recessed at the end face. The slotted groove is advantageous for use with a slotted screwdriver, while the Phillips head groove is advantageous for use with a Phillips head screwdriver. By using a screwdriver, the knob 261 can be rotated and adjusted more easily, making operation more convenient.

[0080] Reference Figure 5 and Figure 6The floating element 24 includes a first cylindrical body 241 and an annular boss 242. The first cylindrical body 241 is a cylindrical structure with a hollow interior and open ends. A threaded hole is located on the inner wall of the first cylindrical body 241, and the first cylindrical body 241 can be connected to the adjusting element 26 through the threaded hole.

[0081] In addition, the annular boss 242 is provided at one end of the first cylinder 241 and located on the outer periphery. Usually, the two are connected as one piece to ensure that they have greater structural strength. On this basis, the first cylinder 241 is placed vertically, and the annular boss 242 is slidably connected to the outer shell 21. Under the action of the annular boss 242, the floating element 24 can be raised and lowered. At this time, one end of the spring 25 is sleeved on the first cylinder 241 and abuts against the annular boss 242. The first cylinder 241 can support one end of the spring 25.

[0082] Specifically, in order to enable the floating element 24 to slide and connect with the outer shell 21, the opposite sides of the annular boss 242 are provided with outwardly protruding guide protrusions 2421. Usually, the guide protrusions 2421 are integrally connected with the annular boss 242. At the same time, the inner walls of the opposite sides of the outer shell 21 are provided with guide grooves 213. Specifically, the guide grooves 213 are recessed in the inner wall of the lower shell 212. On this basis, the two guide protrusions 2421 slide and engage with the two guide grooves 213 respectively.

[0083] By adopting the above scheme, on the one hand, with the cooperation of the two pairs of guide protrusions 2421 and guide grooves 213, the opposite sides of the floating element 24 can be guided by sliding, making the floating element 24 less prone to uneven load and the lifting and lowering movement smoother, providing a basis for achieving precise adjustment of the pressing force; on the other hand, the two sets of mutually cooperating guide protrusions 2421 and guide grooves 213 can also make the floating element 24 less prone to shaking during the lifting and lowering displacement, making the structure more stable.

[0084] Based on this, to further optimize the pressing feel, a second cylinder 221 is provided on the shaft core 22. Specifically, the second cylinder 221 is set vertically, with its top end integrally connected to the shaft core 22, and its bottom end open and facing the top end of the first cylinder 241. In addition, the inner diameter of the second cylinder 221 is consistent with the outer diameter of the first cylinder 241. At this time, the first cylinder 241 and the second cylinder 221 can be sleeved on each other. The first cylinder 241 and the second cylinder 221 can slide and abut against each other in the sleeved state. At this time, the other end of the spring 25 away from the first cylinder 241 is sleeved on the second cylinder 221.

[0085] Based on the above configuration, on the one hand, the two ends of the spring 25 can be positioned by the interaction of the first cylinder 241 and the second cylinder 221. During the extension and retraction of the spring 25, the middle part is not easy to twist outward, and the structure is more stable. On the other hand, the first cylinder 241 and the second cylinder 221, which are interlocked and slide against each other, can position the shaft core 22, so that the shaft core 22 is not easy to tilt or deflect when it is pressed down to the bottom. However, since this solution involves the triggering of the magnetic shaft 2, there is a difficult technical obstacle to be solved. When the magnetic shaft 2 is pressed to the bottom, it is easy to generate slight shaking. When shaking occurs, it is easy to be captured by the Hall sensor, which will lead to the false triggering of the disconnection signal and affect the accuracy of pressing.

[0086] Based on this, this solution, through the cooperation of the first cylinder 241 and the second cylinder 221, utilizes the sliding cooperation of the first cylinder 241 and the second cylinder 221 to reduce the shaking of the switch core 22, improve the accuracy of pressing, overcome the technical obstacle of key switch shaking, and obtain a high-performance magnetic axis keyboard that can improve the accuracy of pressing while realizing the adjustment of pressing force.

[0087] Furthermore, continue to refer to Figure 6 To ensure a more balanced pressing force, the outer casing 21 has a central axis, which is defined as O for ease of understanding. The central axis O passes through the center of the outer casing 21 in the vertical direction, which is equivalent to passing through the middle of the outer casing 21. Based on this, the shaft core 22, the floating element 24, the spring 25 and the adjusting element 26 are all located on the central axis.

[0088] Based on the above settings, when the button is pressed, the pressing force can be transmitted from the middle of the magnetic shaft 2 to each component, so that the pressing force can be applied evenly to each component, the structure is not prone to uneven load friction, and the noise can also be reduced simultaneously.

[0089] Based on this, the magnet 222 and the Hall sensor 23 are offset to the outside of the central axis. On the one hand, by offsetting the magnet 222 and the Hall sensor 23 to the outside, assembly space can be provided for the main components that perform the pressing trigger, such as the shaft core 22, the floating element 24, the spring 25, and the adjusting element 26, making good use of the internal space of the housing 21, resulting in a compact structure without the need to increase the size of the housing 21. On the other hand, by offsetting the magnet 222 and the Hall sensor 23 to the outside of the central axis, there are no obstructions between them, thus avoiding interference from other components. In addition, no matter how the elastic force of the spring 25 changes, it will not affect the distance travel between the magnet 222 and the Hall sensor 23, ensuring good pressing accuracy.

[0090] Reference Figure 3 and Figure 6Furthermore, it also includes a pressure sensor 8 and a control system. The pressure sensor 8 is a ring-shaped flexible resistive thin-film pressure sensor. This type of pressure sensor 8 has a thin and light structure, and its electrical signal changes are mainly triggered by the deformation of the thin-film element under force. The pressure sensor 8 is sleeved on the first cylinder 241 and placed on the annular boss 242. At this time, the pressure sensor 8 is positioned between the floating element 24 and the spring 25, and abuts against the spring 25. When the spring 25 is subjected to pressure, it can synchronously act on the pressure sensor 8. The pressure sensor 8 is used to acquire pressure signals and is electrically connected to the terminal 4 of the lower shell 212.

[0091] In addition, the control system is connected to pressure sensor 8, which sends pressure signals to the control system. The control system then obtains the pressure value based on these signals. The control system mainly includes a PCB board and an MCU main control chip mounted on the PCB board. The PCB board is electrically connected to terminal 4. When pressure sensor 8 generates a pressure signal, it is sent to the receiving end of the MCU main control chip via terminal 4 and the circuit board. The MCU main control chip analyzes and processes the pressure signal to obtain the pressure value. The MCU main control chip also has a built-in output module, whose output is electrically connected to a computer device. The output module then uploads the pressure value to the computer device, enabling the computer device to display and monitor the pressure values ​​of each key.

[0092] Based on this, when the pressure value is lower than the recommended pressure value, the user can adjust the trigger force of the corresponding key according to the actual pressure value, thereby improving the consistency of the feel of each key and avoiding the imbalance of the feel of some keys, thus further optimizing and improving the keyboard's user experience.

[0093] The high-performance magnetic axis keyboard provided in this embodiment has the following beneficial effects:

[0094] 1. The key pressure can be adjusted by operating the adjustment element 26, which meets the diverse needs of different users for keyboard key pressure, and also overcomes the long-standing defect of the magnetic axis 2 keyboard having a monotonous feel.

[0095] 2. It can reduce the occurrence of shaking when pressing, making the structure more stable and less prone to disconnection;

[0096] 3. It can monitor the pressure value of each key, so that you can adjust or customize the pressing force of each key, making the product experience richer and more flexible.
