Description

Technical Field

[0001] The present invention relates to the technical field of computer input devices, and in particular to a high-performance magnetic axis keyboard. Background Art

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

[0003] For example, in the Chinese utility model patent with the announcement number CN221529155U, a keyboard is disclosed in which the magnetic axis can be replaced with a mechanical axis. The magnetic axis keyboard displayed therein mainly realizes the triggering effect through the mutual induction between the magnetic axis body and the Hall module.

[0004] However, current magnetic keyboards still have many shortcomings. Due to the limitations of their architecture, most magnetic keyboards rely on springs to achieve linear rebound upon pressing. This results in a single trigger feel, making it difficult to meet the diverse demands of different users for different pressing forces. Furthermore, with long-term use, the springs can experience mechanical fatigue, causing changes in the pressing force and feel, while also potentially affecting the sensitivity of the magnetic keyboard. The existing technology still lacks a high-performance magnetic keyboard with adjustable pressing force, thus requiring improvement.

[0005] The above information is presented as background information only to assist with an understanding of the present disclosure and is not a determination or admission that any of the above may be applicable as prior art with respect to the present disclosure. Summary of the Invention

[0053] In order to make the purposes, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0054] In the description of the present 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 a centrally located component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be a centrally located component.

[0055] In addition, terms such as "long", "short", "inside", and "outside" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientation structure, and should not be understood as a limitation of the present invention.

[0056] The following is combined with Figure 1-6 The technical solution of the present invention is further illustrated through specific implementation methods.

[0057] Please refer to Figure 1 An embodiment of the present invention provides a high-performance magnetic axis keyboard, including a keyboard body 1, a magnetic axis 2 and a keycap 3. The magnetic axis 2 is installed on the keyboard body 1, and the keycap 3 is installed on the magnetic axis 2. The user triggers the magnetic axis 2 by pressing the magnetic axis 2, thereby generating an electrical signal, which is input into the computer device through the circuit system in the keyboard body 1. The triggering principle of the keyboard will not be elaborated here.

[0058] Reference Figure 2 and Figure 3 To solve the problem that the pressing force cannot be adjusted, 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 housing 21 is used to provide installation locations for various components and members, and the housing 21 is connected to the keyboard body 1. In this embodiment, the magnetic axis 2 is described in a normal use state, that is, the magnetic axis 2 is described in a vertical installation state. At this time, the housing 21 mainly includes an upper shell 211 and a lower shell 212. The upper shell 211 and the lower shell 212 are interlocked with each other through buckles, thereby fixing each other and forming a cavity inside the housing 21. In addition, buckles are also provided on the outer periphery of the lower shell 212. The lower shell 212 is interlocked with the positioning plate of the keyboard body 1 through the buckles, thereby achieving installation of the housing 21.

[0060] On this basis, the shaft core 22 is arranged in the housing 21 for lifting. Specifically, a through hole 2111 is opened at the top of the housing 21, that is, the through hole 2111 is set through the upper shell 211. By inserting the shaft core 22 into the through hole 2111, the shaft core 22 can be lifted and displaced under the guidance of the through hole 2111. At the same time, the top of the shaft core 22 is a cross structure for connecting with the keycap 3.

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

[0062] Furthermore, the magnet 222 is mainly used for induction and coordination with the Hall sensor 23. Specifically, the Hall sensor 23 is arranged at the lower shell 212 of the housing 21 and is arranged opposite to 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 induction coordination. 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 is 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 via 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 in the housing 21, and the spring 25 is respectively connected to the shaft core 22 and the floating element 24. The spring 25 is based on 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, and the spring 25 drives the shaft core 22 to reset.

[0064] Furthermore, the adjusting element 26 is disposed on 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, so as to control the initial compression amount of the spring 25 .

[0065] Specifically, the adjustment element 26 has two application states on 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 floating element 24 and the shaft core 22 of the spring 25, thereby shortening the length of the spring 25 in the initial state, which is equivalent to increasing the initial compression amount of the spring 25. At this time, when pressing the button, the force required will increase, the feel will become heavier, and a better feedback feeling can be obtained, and it can also prevent accidental touches.

[0067] On the other hand, when the adjusting element 26 drives the floating element 24 to move downward, the space between the spring 25 and the floating element 24 and the shaft core 22 will increase, 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, when pressing the key, the effort required is reduced, and the feel will become lighter, which can improve typing speed and comfort, and also reduce fatigue.

[0068] By adopting the above scheme, this embodiment provides a high-performance magnetic axis keyboard that can control pressing. By operating the adjustment element 26, the initial compression amount of the spring 25 can be changed, and then the pressing force can be changed, which meets the diverse needs of different users for keyboard pressing force, and also overcomes the long-standing defect of the single feel of the magnetic axis 2 keyboard.

[0069] Reference Figure 4 and Figure 5 In order to adjust the structural height of the floating element 24 , the adjusting element 26 provided in the embodiment of the present application includes a knob 261 and a threaded connecting shaft 262 .

[0070] The knob 261 is rotatably mounted on the housing 21. Specifically, the knob 261 in this embodiment is a pancake-shaped knob 261, which is horizontally mounted. The bottom of the housing 21 has a first avoidance hole 2121 for exposing the knob 261. The first avoidance hole 2121 is disposed through the lower housing 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 middle part is arranged vertically, 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 scheme, by rotating the knob 261, the knob 261 will drive the threaded connection shaft 262 to rotate. With the mutual cooperation of the external thread and the threaded hole, by changing the specific rotation direction of the knob 261, such as forward or reverse rotation, the floating element 24 can be pushed up and down to achieve the height adjustment function. The operation is easy and quick, and the structure is simple, which can also meet the cost requirements.

[0072] Further, continue to refer to Figure 4 and Figure 5 To ensure that the knob 261 can rotate stably within the housing 21, the adjustment element 26 further includes a limiting cover plate 263. The bottom of the housing 21 is provided with a mounting groove 6 that communicates with the first avoidance hole 2121. Specifically, the mounting groove 6 is recessed from the outside to the inside and is arranged on the inner bottom wall of the lower shell 212. 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 achieving sliding installation of the knob 261 within the mounting groove 6.

[0073] On this basis, the limiting cover plate 263 is located above the knob 261 , wherein a second avoidance hole 2631 for the threaded connection shaft 262 to pass through is provided in the middle of the limiting cover plate 263 , and the limiting cover plate 263 is movably buckled with the housing 21 .

[0074] Specifically, buckles (not shown in the figure) are provided inside the shell 21 and around the limiting cover 263, and the two are elastically connected through the buckles to achieve a movable buckling effect. The buckle is a conventional setting method, and the specific structure of the buckle is not described here. Under the action of the buckle, when the limiting cover 263 is buckled to the shell 21, the limiting cover 263 blocks the installation groove 6 and limits the knob 261 from loosening.

[0075] Based on the above scheme, 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 further improve the compactness of the structure when it is rotated. On the other hand, by setting the limit cover 263, the knob 261 can be upper-limited in the vertical direction, so that the knob 261 is more stable during use and not easy to fall off. In addition, the overall installation process of the knob 261 and the limit cover 263 is convenient. You only need to put the knob 261 into the mounting groove 6 and then install the limit cover 263. It is quick and convenient.

[0076] Further, refer to Figure 5The outer periphery of the knob 261 is provided with a passing point protrusion 5, and the surface of the passing point protrusion 5 is a spherical surface. At the same time, the groove wall of the mounting groove 6 is provided with a plurality of passing point grooves 61 that are movably engaged with the passing point protrusion 5. The passing point groove 61 has a spherical surface that is adapted to the shape of the passing point protrusion 5. The passing point protrusion 5 and the passing point groove 61 are used to make the knob 261 produce a passing point feel when rotating.

[0077] In the above scheme, during the rotation of the knob 261, the knob 261 and the shell 21 are both made of plastic, so they can be elastically deformed, and the passing point protrusion 5 can be switched to different passing point grooves 61 in sequence. On the one hand, it can realize the fine gear adjustment function, make the force adjustment more precise, and realize fine adjustment; on the other hand, it can enable the knob 261 to stay at a specific angle. If there is no external force, it is not easy to rotate loose by itself, and the pressing force of the button can be maintained at a constant value.

[0078] Further, refer to Figure 4 The bottom of the knob 261 is also provided with a positioning column 2611. The positioning column 2611 is perpendicular to the knob 261 and is located on the side of the knob 261 facing away from the threaded connection shaft 262. Figure 1 A positioning hole 7 is provided on the keyboard body 1. Specifically, the positioning hole 7 is located on the PCB board of the keyboard body 1. The positioning column 2611 is plugged into the positioning hole 7. With the plug-in cooperation between the two, the magnetic axis 2 can be positioned during installation, and the installation accuracy of the magnetic axis 2 is optimized and improved.

[0079] In addition, the positioning post 2611 on the knob 261 can also facilitate the user to use it to apply rotational force to the knob 261, so as to operate the knob 261 to rotate. In one embodiment, the outer peripheral surface of the positioning post 2611 on the knob 261 can be processed to form a pattern to increase friction, thereby facilitating the rotation of the positioning post 2611, thereby driving the knob 261 to rotate; in the embodiment provided in this embodiment, the end of the positioning post 2611 has a flat groove or a cross groove. It can be understood that the one end here refers to the end of the positioning post 2611 away from the knob 261, and the flat groove or the cross groove is recessed at the end face. At this time, the flat groove can be conducive to cooperating with a flat screwdriver, while the cross groove is conducive to cooperating with a cross screwdriver. By using a screwdriver tool, the knob 261 can be rotated and adjusted more easily, and the operation is more convenient.

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

[0081] In addition, the annular boss 242 is arranged at one end of the first cylinder 241 and is located on the outer periphery. Usually, the two are connected as one to ensure that there is greater structural strength between the two; 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 lifted and moved. 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 be slidably connected to the outer shell 21, the annular boss 242 is provided with outwardly protruding guide protrusions 2421 on opposite sides. Usually, the guide protrusion 2421 is integrally connected to the annular boss 242; at the same time, the inner walls on opposite sides of the outer shell 21 are respectively 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 are slidably fitted in the two guide grooves 213 one by one.

[0083] By adopting the above-mentioned scheme, on the one hand, with the mutual cooperation of the two pairs of guide protrusions 2421 and the guide grooves 213, the opposite sides of the floating element 24 can obtain sliding guidance respectively, so that the floating element 24 is not easily overloaded, and the lifting and lowering movement is 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 likely to shake during the lifting and lowering movement, and the structure is more stable.

[0084] On this basis, in order to further optimize the pressing feel, a second cylinder 221 is provided on the shaft core 22. Specifically, the second cylinder 221 is vertically arranged, and its top end is integrally connected to the shaft core 22, and the bottom end is 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 socketed with each other, and the first cylinder 241 and the second cylinder 221 can slide and abut against each other in the socketed state. At this time, the other end of the spring 25 away from the first cylinder 241 is socketed on the second cylinder 221.

[0085] Based on the above arrangement, on the one hand, under the interaction of the first cylinder 241 and the second cylinder 221, the two ends of the spring 25 can be positioned, and during the extension and contraction process, the middle part of the spring 25 is not easily twisted outward, and the structure is more stable; on the other hand, the first cylinder 241 and the second cylinder 221, which are mutually socketed and slidably matched with each other, can position the shaft core 22, so that the shaft core 22 is not easily tilted and deflected when pressed down to the bottom. Among them, since this solution involves the triggering of the magnetic axis 2, there is a difficult-to-solve technical obstacle in the triggering of the magnetic axis 2. Since the magnetic axis 2 is prone to slight shaking when pressed to the bottom, when shaking occurs, it is easy to be captured by the Hall sensor, which will cause the disconnection signal to be mistakenly touched, affecting the accuracy of the press.

[0086] Based on this, this solution uses the sliding cooperation between the first cylinder 241 and the second cylinder 221 to reduce the shaking of the shaft core 22, improve the accuracy of pressing, overcome the technical obstacles of key shaft shaking, and obtain a high-performance magnetic axis keyboard that can achieve pressure adjustment and improve pressing accuracy.

[0087] Further, continue to refer to Figure 6 In order to make the pressing force more balanced, the shell 21 has a central axis. For ease of understanding, the central axis is defined as O. The central axis O passes through the collective center of the shell 21 along the vertical direction, which is equivalent to passing through the middle of the shell 21. On this basis, 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 arrangement, when the button is pressed, the pressing force can be transmitted from the middle of the magnetic axis 2 to each component, so that the pressing force can be evenly applied to each component, the structure is not prone to unbalanced load friction, and the noise can also be reduced simultaneously.

[0089] On this basis, 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 press triggering, such as the shaft core 22, the floating element 24, the spring 25, and the adjustment element 26, which make good use of the internal space of the shell 21, and the structure is compact, without the need to increase the size of the shell 21. On the other hand, by offsetting the magnet 222 and the Hall sensor 23 to the outside of the central axis, there is no obstruction between the two, thereby preventing other components from interfering with the sensing of the two. 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, and the pressing accuracy is well guaranteed.

[0090] Reference Figure 3 and Figure 6, further comprising a pressure sensor 8 and a control system. The pressure sensor 8 is a ring-shaped flexible resistive film pressure sensor 8. This type of pressure sensor 8 has a thin and lightweight structure, and primarily operates by causing electrical signal changes when the film element is deformed under stress. The pressure sensor 8 is sleeved on the first cylinder 241 and placed on the annular boss 242. The pressure sensor 8 is disposed between the floating element 24 and the spring 25 and abuts against the spring 25. The spring 25, when subjected to pressure, can synchronously act on the pressure sensor 8. The pressure sensor 8 is used to obtain a pressure signal and is electrically connected to the terminal 4 of the lower shell 212.

[0091] In addition, the control system is connected to the pressure sensor 8, which sends a pressure signal to the control system, and the control system obtains a pressure value based on the pressure signal. The control system mainly includes a PCB board and an MCU main control chip arranged on the PCB board, wherein the PCB board is electrically connected to the terminal 4. When the pressure sensor 8 generates a pressure signal, the pressure signal is sent to the receiving end of the MCU main control chip via the terminal 4 and the circuit board. The MCU main control chip obtains the pressure value by analyzing and processing the pressure signal, and the MCU main control chip has a built-in output module. The output end of the MCU main control chip is electrically connected to the computer device, and the pressure value is uploaded to the computer device through the output module, so that the computer device can display and monitor the pressure value of each key position.
