Description

Technical Field

[0001] The present invention relates to switch control technology using electromagnetic induction, and relates to improvements in induction sensitivity and input stability, so as to improve input stability of notebook computers, electronic equipment, keyboards, etc., and relates to structural improvements of keyboards, keys, and shaft cores. Background Art

[0002] Using the electromagnetic induction principle to achieve switch control is a relatively efficient control method, which has gradually been applied in electronic products, such as keyboards, laptops and electronic products that require key operation. For example, magnetic axis switches (also called Hall axis switches) or inductive axis switches are used to achieve corresponding switch control. According to the electromagnetic induction principle, in order to achieve switch switching, the magnetic part or the conductor must be moved relative to the magnetic sensor or the inductive element.

[0003] In the magnetic shaft switch of the prior art, the magnetic part is fixed on the shaft core of the shaft body. For example, in document 1, the magnet is pasted on the shaft core and can move toward the magnetic sensor (Hall element) as the shaft core moves; for example, in document 2, the magnet is connected to the shaft core by interference fit and can move toward the magnetic sensor (Hall element) as the shaft core moves.

[0004] In the inductive shaft switch of the prior art, the trigger member that cooperates with the inductive element is also fixed on the shaft core of the shaft body. For example, the trigger member (metal column) in Document 3 is also connected to the bottom of the shaft core (guide column) by plugging, and can move toward the inductive element with the movement of the shaft core; for example, the trigger member (magnetic core) in Document 4 is also connected to the bottom of the shaft core by plugging, and can move toward the inductive element with the movement of the shaft core.

[0009] Affected by factors such as the product's working principle and production process, although technicians are constantly improving related products, the sensing sensitivity of magnetic axis switches and inductive axis switches in the existing technology, as well as the input stability of the keyboard are still insufficient, and will affect consumers' user experience in certain scenarios. Summary of the invention

[0010] As one aspect of the improvement, a method for improving input stability is provided, which is applied to a keyboard, wherein the keyboard is provided with a key and a magnetic sensor corresponding to the key, wherein a magnetic member is provided on the key, and when the key is pressed, the magnetic member moves toward the magnetic sensor as the key is pressed, and the magnetic member can rotate relative to the magnetic sensor during the process of moving toward the magnetic sensor. Compared with the prior art, the magnetic member has an additional rotation stroke on the basis of moving with the key, so that the magnetic field change process sensed by the magnetic sensor is smoother and more uniform, so that the induction sensitivity of the magnetic sensor to the key input process of the keyboard is increased, and the input stability of the keyboard is improved.

[0011] Furthermore, the magnetic part can rotate relative to the magnetic sensor during at least part of the process of moving toward the magnetic sensor. For example, the magnetic part moves linearly in the initial stage of the downward movement, and starts to rotate when the magnetic part descends to the starting position where it can rotate. Of course, the magnetic part can also only move linearly in the final stage of the downward movement. The magnetic part can rotate synchronously when descending first, and then descend linearly without rotating. It can also not rotate in the initial stage and the final stage of the downward movement, but only rotate in the middle stage. In short, the magnetic part only needs to rotate relative to the magnetic sensor during part of the process of moving toward the magnetic sensor.

[0012] Furthermore, during the rotation of the magnetic element relative to the magnetic sensor, the magnetic element moves relative to the magnetic sensor along the trajectory of the spiral line. The magnetic element only needs to be able to rotate during the descent process. The magnetic element may not move relative to the magnetic sensor along the trajectory of the spiral line but may move along other trajectories. Movement along the spiral trajectory is more efficient, easy to control and convenient for industrial use, so as to better improve the input stability of the keyboard.

[0013] Furthermore, the spiral line is a spiral line with a gradually changing pitch, which can change the approach rate of the magnetic part relative to the magnetic sensor. Since the user presses the key vertically downward during the key pressing process, the pitch can be adjusted to adjust the distance of the magnetic part relative to the magnetic sensor when pressing vertically downward for a unit distance, thereby realizing input and sensing control, improving the sensing sensitivity of the magnetic sensor, and improving input stability.

[0014] Furthermore, the pitch of the spiral portion away from one end of the magnetic sensor is smaller than the pitch of the spiral portion close to the end of the magnetic sensor. Due to the smaller pitch, the magnetic part rotates a longer distance when moving vertically downward per unit distance, making the speed at which the magnetic part approaches the magnetic sensor slower, further improving the sensing accuracy and input stability.

[0015] Furthermore, the magnetic part rotates around an axis when rotating. It is only necessary to ensure that the magnetic part can rotate during the descent process, and the magnetic part may not rotate along a specific axis. It is more efficient to make the magnetic part rotate around an axis, which is easier to control and convenient for industrial use, so as to better improve the input stability of the keyboard.

[0016] Furthermore, the axis passes through the magnetic sensor, so that the magnetic part can achieve better induction detection effect when approaching the magnetic sensor. Of course, there is no restriction that the axis must pass through the magnetic sensor, as long as the magnetic part can move toward the magnetic sensor and rotate relative to the magnetic sensor.

[0017] Furthermore, the axis is coaxial with a vertical center line of the magnetic sensor.

[0018] Furthermore, when the pressing of the button is released, the button can be reset under the action of elastic force.

[0019] Furthermore, the button is reset under the action of the elastic member.

[0020] Furthermore, the elastic member is a spring, and other elastic members known in the art are also acceptable. The selection of the elastic member itself is not an improvement of the present invention.

[0021] Furthermore, when the button is pressed and the button is released, the magnetic part moves away from the magnetic sensor as the pressing is released, and the magnetic part can rotate relative to the magnetic sensor during at least part of the process of moving away from the magnetic sensor. The rotation of the magnetic part during the process of moving away from the magnetic sensor can improve the sensing accuracy of the rapid trigger function (Rapid Trigger) of the button.

[0022] Furthermore, the movement trajectory of the magnetic part during the resetting process is opposite to the movement trajectory of the key during the pressing process. In this way, the existing trajectory of the magnetic part when it moves close to the magnetic sensor can be fully utilized, making the movement of the magnetic part more efficient, easier to control and convenient for industrial use, and better improving the input stability of the keyboard. Of course, the movement trajectory of the magnetic part during the resetting process can also be other trajectories, and it does not have to be opposite to the movement trajectory during the pressing process.

[0023] Furthermore, the magnetic member is a magnet. Of course, it can also be a common magnetic member in the art. The selection of the magnetic member itself is not an improvement point of the present invention.

[0024] As one aspect of improvement, a method for improving input stability is provided. The magnetic sensor in the method can be replaced by an inductor element, and the magnetic part can also be replaced by a magnetic part or a conductor that realizes electromagnetic induction corresponding to the inductor element. In this way, input control of the keyboard and keys can also be realized. The specific implementation principle is the existing technology and will not be elaborated here.

[0025] Furthermore, the magnetic part or conductor corresponding to the inductor element can be selected as a magnet or a metal rod. The metal rod can be a commonly used conductive metal or alloy. For example, the metal rod can be an aluminum rod, a copper rod, a silver rod or other metal with good conductive effect. Among them, the processing performance and cost of the aluminum rod have great advantages, which is convenient for industrial application.

[0026] As an aspect of improvement, corresponding to the aforementioned method, there is also provided a keyboard, which is provided with a PCB and a key, the key is connected to the PCB, the PCB is provided with a magnetic sensor corresponding to the key, and the key is provided with a magnetic member, and the magnetic member can rotate relative to the magnetic sensor. By setting the magnetic member to be able to rotate relative to the magnetic sensor, the magnetic member can also rotate during the process of moving relative to the magnetic sensor, so that the magnetic field change process sensed by the magnetic sensor is smoother and more uniform, so that the induction sensitivity of the magnetic sensor to the key input of the keyboard is increased, and the input stability of the keyboard is improved.

[0027] Furthermore, when the button is pressed, the magnetic member moves toward the magnetic sensor as the button is pressed, and the magnetic member can rotate relative to the magnetic sensor during the process of moving toward the magnetic sensor.

[0028] Furthermore, the magnetic member can rotate relative to the magnetic sensor during at least a portion of the process of moving toward the magnetic sensor.

[0029] Furthermore, a shaft core is disposed on the button, and when the button is pressed, the shaft core can move toward the magnetic sensor, and the magnetic member is rotatably disposed on the shaft core.

[0030] Furthermore, the magnetic component is a magnet, and of course, it can also be a common magnetic component in the art.

[0031] Furthermore, an elastic member is disposed on the button, and when the button is released from being pressed, the button can be reset under the action of the elastic member.

[0032] Furthermore, the elastic member is a spring, and of course, it can also be a common elastic member in the art.

[0033] Furthermore, a guide is provided on the button, and the magnetic member can move toward the magnetic sensor along the guide track of the guide. Of course, the guide may not be used, and a special driving element may be used to drive the magnetic member to rotate, so that the magnetic member moves toward the magnetic sensor along a predetermined track. For example, a motor may be used to drive the magnetic member to rotate, so that the magnetic member can move toward the magnetic sensor along a predetermined track without a guide.

[0034] Furthermore, at least a portion of the guide track is a spiral line.

[0035] Furthermore, the helix is ​​a helix with a gradually changing pitch.

[0036] Furthermore, the pitch of the helical portion at one end away from the magnetic sensor is smaller than the pitch of the helical portion at one end close to the magnetic sensor.

[0037] Further, the guide member is a guide ring, and the guide ring is provided with a guide block or a guide groove. Of course, the guide ring can also be provided with a guide ring or a guide groove at the same time, and the number of the guide ring and the guide groove can also be not limited to one.

[0039] Furthermore, the magnetic part and the shaft core are rotatably connected via a bearing. The shaft core and the magnetic part can be rotated relative to each other by using the rotating matching structure of the inner and outer rings of the bearing. Of course, the magnetic part and the shaft core can also be connected by other non-bearing rotating connection structures.

[0040] Furthermore, the magnetic part is connected to the inner ring of the bearing, and the shaft core is connected to the outer ring of the bearing. According to actual needs, the material, shape and connection position of the corresponding components are adjusted accordingly. It is also possible to use a structure in which the magnetic part can be connected to the outer ring and the shaft core is connected to the inner ring, as long as a rotatable connection between the magnetic part and the shaft core is achieved.

[0041] Furthermore, the magnetic component is connected to the inner ring of the bearing through a guide column. According to actual needs, the material, shape and connection position of the corresponding parts are adjusted accordingly. The magnetic component can also be directly connected to the bearing without going through the guide column.

[0042] Furthermore, the guide column is connected to the inner ring of the bearing via a spline structure. Depending on actual needs, they may not be connected via a non-spline structure, for example, they may be connected only via an optical axis or other means.

[0043] Furthermore, the shaft core is connected to the outer ring of the bearing through a sleeve, and the sleeve and the outer ring of the bearing are interference fit, for example, a plurality of reinforcing ribs may be provided on the sleeve to assist in achieving the interference fit; or the reinforcing ribs may not be used, and the interference fit may be achieved only by machining dimensions. According to actual needs, the connection may also be achieved without the sleeve or by a connection structure other than the sleeve.

[0044] Furthermore, the shaft sleeve is buckled with the shaft core, and of course, they can also be connected in other ways.

[0045] Furthermore, the shaft sleeve is provided with a buckle, and the shaft core is provided with a slot. Of course, the buckling can also be achieved through other methods or structures.

[0046] Furthermore, the guide column is provided with a guide groove or a guide block corresponding to and matching the guide ring.

[0047] Furthermore, the magnetic member can rotate around an axis.

[0048] Further, the axis passes through the magnetic sensor.

[0049] Furthermore, the axis is coaxial with a vertical center line of the magnetic sensor.

[0050] Furthermore, the magnetic sensor is welded on the PCB, and of course it can also be connected in other ways, such as pasting, etc. The selection of the connection method between the magnetic sensor and the PCB is not an improvement point of the present invention.

[0051] Further, the button is provided with a base and an upper cover, the bottom end of the base is connected to the PCB, the bottom end of the base is provided with a convex column, the PCB is provided with a concave hole, the convex column is plugged and connected with the concave hole on the PCB, the convex column is two, the guide ring is provided on the inner surface of the base, the upper cover is connected with the base to form an accommodating space, the elastic member is provided in the accommodating space, the lower part of the shaft core abuts against the elastic member, wherein the shaft core abuts against the elastic member through the shaft sleeve, the upper part of the shaft core can slide out of the upper cover, the upper cover is buckled with the base, the upper part of the shaft core is provided with a cross shaft, the elastic member is sleeved on the outside of the guide ring, the elastic member is sleeved on the outside of the guide column, the magnetic member is provided in the hole at the bottom of the guide column, and the magnetic member is interference fit with the guide column. The mutual connection between the base, upper cover, elastic member, shaft core, magnetic member, etc. of the button and how the button is connected to the PCB may not be limited to the above description, and is not an improvement of the present invention.

[0052] As an aspect of improvement, a keyboard is provided, in which the magnetic sensor can be replaced by an inductor element, and the magnetic part can also be replaced by a magnetic part or a conductor that realizes electromagnetic induction corresponding to the inductor element. In this way, input control of the keyboard and keys can also be realized. The specific implementation principle is existing technology and will not be elaborated here.

[0053] Furthermore, the magnetic part or conductor corresponding to the inductor element can be selected as a magnet or a metal rod. The metal rod can be a commonly used conductive metal or alloy. For example, the metal rod can be an aluminum rod, a copper rod, a silver rod or other metal with good conductive effect. Among them, the processing performance and cost of the aluminum rod have great advantages, which is convenient for industrial application.

[0054] Furthermore, the inductor element can be in various forms, such as an inductor coil. The inductor coil is easy to process and has the lowest cost. For example, it can be directly printed on a PCB. In order to increase the inductive effect of the inductor coil, the inductor coil can be set to two, respectively set on the upper and lower surfaces of the PCB. Of course, the inductor coil can also be set on the PCB by welding or pasting, wherein the inductor coil can also be set to only one, or more than two. According to the implementation principle, the inductor coil is controlled by a control chip to generate an electromagnetic field, and then cooperates with a magnetic part or a conductor to realize the judgment of the switch. The specific principles are also existing technologies and will not be repeated here.

[0055] Furthermore, in order to improve the coordination effect with the inductive element, a through hole is provided on the PCB for allowing the conductor or magnetic body to move through. This can increase the moving range of the conductor or magnetic body relative to the inductive element and improve the inductive effect. Of course, if the inductive effect between the conductor or magnetic part and the inductive element is sufficient, the through hole can be omitted on the PCB.

[0056] As an aspect of improvement, corresponding to the aforementioned method and keyboard scheme, there is also provided a method for improving sensing sensitivity, which is applied to a key, wherein an axis core is provided on the key, and a magnetic part is provided on the axis core, and when the key is pressed, the magnetic part moves with the axis core, and can rotate relative to the axis core during the process of the magnetic part moving with the axis core. By making the magnetic part rotate relative to the axis core during the pressing and moving process, the manner in which the magnetic part in the key can only move toward the magnetic sensor with the movement of the axis core is changed, and during the process of the key executing the signal input, the magnetic field change process sensed by the magnetic sensor is made smoother and more uniform, so that the sensing sensitivity of the magnetic sensor to the keyboard key input process is increased, that is, the sensing sensitivity of the key is improved.

[0057] Furthermore, the magnetic member can rotate relative to the shaft core during at least a portion of the process of moving with the shaft core.

[0058] Furthermore, the magnetic member rotates around an axis when rotating.

[0059] Furthermore, the axis is coaxial with the vertical center line of the shaft core.

[0060] Furthermore, when the pressing of the button is released, the button can be reset under the action of elastic force.

[0061] Furthermore, when the button is released, the magnetic component moves back to the original position along with the shaft core, and the magnetic component can rotate relative to the shaft core during the process of moving back to the original position along with the shaft core.

[0062] Furthermore, the magnetic member can rotate relative to the shaft core during at least a portion of the process of the shaft core performing the resetting movement.

[0063] Furthermore, the movement trajectory of the magnetic member during the resetting of the button is opposite to the movement trajectory of the button during the pressing of the button.

[0064] Furthermore, during the rotation of the magnetic part relative to the shaft core, as the distance of the shaft core away from the initial position increases, the angle of rotation of the magnetic part gradually changes for each unit distance of the shaft core. In this way, the approach rate of the magnetic part relative to the magnetic sensor can be changed. Since the keyboard user presses the key vertically downward during the keystroke, the distance of the magnetic part relative to the magnetic sensor when pressing vertically downward for a unit distance can be adjusted by adjusting the pitch, thereby realizing input and sensing control, improving the sensing sensitivity of the magnetic sensor, and further improving the input stability.

[0065] Furthermore, the angle gradually increases, that is, the magnetic element needs to rotate a longer distance per unit distance of vertical downward movement, so that the speed at which the magnetic element approaches the magnetic sensor gradually becomes slower, further improving the sensing accuracy and input stability.

[0066] Furthermore, the magnetic member is a magnet.

[0067] Furthermore, the button is reset under the action of the elastic member.

[0070] Furthermore, the conductor corresponding to the inductor element can be selected as a metal rod, and the metal rod can be a commonly used conductive metal or alloy. For example, the metal rod can be an aluminum rod, a copper rod, a silver rod or other metal with good conductive effect.

[0129] Since the keyboard itself and its component structure, assembly connection and basic electromechanical control implementation principles are already existing technologies (such as but not limited to the contents in background documents 1-4), other non-improved parts are not shown in the drawings and will not be repeated in the embodiment part.

[0130] Example 1

[0131] A method for improving input stability, applied to a keyboard, such as Figures 3 to 15 As shown, the keyboard is provided with a key and a magnetic sensor 11 corresponding to the key, and a magnetic member 7 is provided on the key. When the key is pressed, the magnetic member 7 moves toward the magnetic sensor 11 as the key is pressed, and the magnetic member 7 can rotate relative to the magnetic sensor 11 during the movement toward the magnetic sensor 11. Compared with the prior art in which the magnetic member 7 can only move with the pressing of the key once installed in the key, the magnetic member 7 in this embodiment can also rotate relative to the magnetic sensor 11, so that the magnetic field change process sensed by the magnetic sensor 11 is smoother and more uniform, so that the induction sensitivity of the magnetic sensor 11 during the key input process of the keyboard is increased, and the input stability of the keyboard is improved.

[0132] Even though the technical personnel are constantly improving the manufacturing process, such as increasing the processing level of the magnetic sensor 11 and the magnetic part 7, they are still subject to the influence of the manufacturing and assembly processes in the actual mass production. On the one hand, the magnetic part 7 and other parts will inevitably have uneven magnetic field distribution. The different internal densities of the magnetic parts and the gaps inside the magnetic parts during the manufacturing process of the magnetic parts make the quality and material thickness of the magnetic parts unevenly distributed, resulting in uneven magnetic field distribution. Figure 1 The thickness of the magnetic part is uneven. The thickness on the right side of the magnetic part is smaller than that on the left side, which leads to uneven quality and material of the magnetic part. Figure 2 It shows that the density on the left side of the magnetic part is significantly smaller than that on the right side (the denser the black dots, the greater the density), which leads to uneven quality and material of the magnetic part. In addition, during the magnetization process, the magnetic field distribution of the magnetic part will be uneven due to insufficient processing accuracy. This is particularly obvious in the scenario where multiple magnetic fields are set on a single magnetic part, which will cause one or several magnetic fields to be too large or too small, resulting in uneven distribution of the entire magnetic field. Magnetic parts with uneven magnetic fields are used on keyboards and keys, which will also affect the input stability of the keyboard to a certain extent.

[0133] By utilizing the method in the embodiment, the magnetic component 7 can rotate relative to the magnetic sensor 11 during the process of moving toward the magnetic sensor 11, which can greatly improve the input instability problem caused by the uneven magnetic field of the magnetic component 7. During the process of the magnetic component 7 moving toward the magnetic sensor 11, even if the magnetic field is uneven at a certain place, the magnetic component 7 rotates, so that the magnetic field sensed by the magnetic sensor 11 changes more evenly, which can improve the input instability phenomenon caused by the uneven magnetic field of the magnetic component 7. On the other hand, during the mass production and installation of the keyboard, the installation positions of the main parts such as the magnetic component 7 and the magnetic sensor 11 may also have certain deviations. For example, the magnetic sensor is biased toward the side with a weaker magnetic field. In the prior art, when a key is pressed, it may not be accurately sensed due to the small magnetic flux, resulting in unstable input. By utilizing the method in this embodiment, the magnetic component 7 rotates to make up for the above defects at the end with a strong magnetic field, thereby improving the impact of this type of installation deviation on input accuracy and enhancing input stability.

[0134] The magnetic member 7 can rotate relative to the magnetic sensor 11 at least partially during the process of moving toward the magnetic sensor 11. For example, the magnetic member 7 moves linearly in the initial stage of the downward movement, which can be a linear movement before contacting the lower guide member, or a linear movement along the guide member; the magnetic member 7 starts to rotate only when it descends to the rotation starting position of the guide track of the guide member;

[0135] Of course, the magnetic member 7 may also move only linearly in the final stage of the downward movement; the magnetic member 7 may first rotate synchronously when descending, and then descend linearly without rotating; or it may not rotate in the initial and final stages of the downward movement, but only rotate in the middle stage. In short, it is sufficient that at least a portion of the process during which the magnetic member 7 moves toward the magnetic sensor 11 is rotated relative to the magnetic sensor 11.

[0136] like Figure 5-8 , Fig.15 During the rotation of the magnetic member 7 relative to the magnetic sensor 11, the magnetic member 7 moves relative to the magnetic sensor 11 along the trajectory of the spiral line. In some embodiments, the spiral line is a spiral line with a gradually changing pitch (not clearly shown in the drawings), for example, the pitch of the spiral line portion at one end away from the magnetic sensor 11 is smaller than the pitch of the spiral line portion at one end close to the magnetic sensor 11, that is, when moving vertically downward per unit distance, the magnetic member 7 needs to rotate a longer distance, so that the speed of the magnetic member 7 approaching the magnetic sensor gradually becomes slower, further improving the sensing accuracy and input stability.

[0137] like Figure 6 , 7 As shown, the magnetic member 7 rotates around an axis when rotating, the axis passes through the magnetic sensor 11, and the axis is coaxial with the vertical center line 200 of the magnetic sensor 11. The magnetic member 7 is a magnet, and the magnetic member 7 can be a cylindrical magnet.

[0138] When the button is released from being pressed, the button can be reset under the action of elastic force. When the button is released from being pressed, the magnetic member 7 moves away from the magnetic sensor 11 as the pressing is released. The magnetic member 7 can rotate relative to the magnetic sensor 11 in at least part of the process of moving away from the magnetic sensor 11. The rotation in this reverse process can improve the sensing accuracy of the rapid trigger function (Rap id Trigger) of the button. In some embodiments, the movement trajectory of the magnetic member 7 during the resetting of the button is opposite to the movement trajectory during the pressing of the button. Of course, the movement trajectory of the magnetic member 7 during the resetting process can also be other trajectories, not necessarily opposite to the movement trajectory during the pressing process. For example, the magnetic member 7 can be reset along a straight trajectory away from the magnetic sensor 11, or the magnetic member 7 can be moved away from the magnetic sensor 11 along other rotatable trajectories (for example, a spiral trajectory parallel to the original trajectory) that have a certain displacement from the original trajectory close to the magnetic sensor 11.

[0139] The button is reset under the action of the elastic member 8, such as the elastic member 8 is a spring.

In some embodiments, the spiral line is a spiral line with a gradually changing pitch (not clearly shown in the drawings), for example, the pitch of the spiral line portion at one end away from the magnetic sensor 11 is smaller than the pitch of the spiral line portion at one end close to the magnetic sensor 11, that is, when moving vertically downward per unit distance, the magnetic member 7 needs to rotate a longer distance, so that the speed at which the magnetic member 7 approaches the magnetic sensor gradually becomes slower, further improving the sensing accuracy and input stability.

[0149] Furthermore, the magnetic member 7 can rotate around an axis. The axis passes through the magnetic sensor 11 , and the axis is coaxial with the vertical center line 200 of the magnetic sensor 11 .

[0150] Furthermore, the magnetic sensor 11 is welded on the PCB 10, and of course it can also be connected by other means, such as pasting, etc. The selection of the connection method between the magnetic sensor 11 and the PCB 10 is not an improvement point of the present invention.

[0152] Example 3

[0153] A method for improving the inductive sensitivity corresponding to embodiments 1 and 2 is applied to a key, wherein an axis core 3 is provided on the key, and a magnetic member 7 is provided on the axis core 3. When the key is pressed, the magnetic member 7 moves with the axis core 3, and can rotate relative to the axis core 3 during the process of the magnetic member 7 moving with the axis core 3. Compared with the prior art in which the magnetic member 7 can only move with the pressing and movement of the key once installed in the key, the magnetic member 7 in this embodiment can rotate relative to the magnetic sensor 11, so that the magnetic field change process sensed by the magnetic sensor 11 is smoother and more uniform, so that the inductive sensitivity of the magnetic sensor 11 during the key input process of the keyboard is increased, the inductive sensitivity of the key is improved, and a unique touch with a certain damping feeling is provided, enriching the tactile experience of consumers when pressing the key.

[0154] Furthermore, the magnetic member 7 can rotate relative to the shaft core 3 during at least a portion of the process of moving with the shaft core 3. Figure 6 , 7 As shown, the magnetic member 7 rotates around an axis when rotating. The axis is coaxial with the vertical center line 200 of the shaft core 3 (in the figure, the vertical center lines of the shaft core 3 and the magnetic sensor 11 coincide with each other and are both marked 200).

[0155] Further, when the button is released from being pressed, the button can be reset under the action of elastic force. When the button is released from being pressed, the magnetic member 7 moves with the shaft core 3 to reset, and the magnetic member 7 can rotate relative to the shaft core 3 during the process of moving with the shaft core 3 to reset. The magnetic member 7 can rotate relative to the shaft core 3 during at least part of the process of moving with the shaft core 3 to reset. The movement trajectory of the magnetic member 7 during the reset process of the button is opposite to the movement trajectory during the pressing process of the button.

[0156] Furthermore, in some embodiments, during the rotation of the magnetic member 7 relative to the shaft core 3, as the distance of the shaft core 3 away from the initial position increases, the angle of rotation of the magnetic member 7 gradually changes for each unit distance of movement of the shaft core 3 (not clearly shown in the drawings). For example, as the angle gradually increases, that is, for each unit distance of vertical downward movement, the magnetic member 7 needs to rotate a longer distance, so that the speed at which the magnetic member 7 approaches the magnetic sensor gradually becomes slower, further improving the sensing accuracy and input stability.

[0157] Furthermore, the magnetic member 7 is a magnet, preferably a cylindrical magnet.

Compared with the prior art, the magnetic member 7 of this example can rotate relative to the shaft core 3, and can rotate relative to the shaft core 3 during the pressing and moving process of the magnetic member 7, which changes the way in which the magnetic member 7 in the key can only move toward the magnetic sensor 11 with the movement of the shaft core 3. When the key is in the process of executing signal input, the magnetic field change process sensed by the magnetic sensor 11 is smoother and more uniform, so that the inductive sensitivity of the magnetic sensor 11 to the key input process of the keyboard is increased, that is, the inductive sensitivity of the key is improved.

[0161] Further, such as Figure 5-8 , Fig.15 As shown, when the key is pressed, the magnetic member 7 moves with the shaft core 3, and can rotate relative to the shaft core 3 during the process of the magnetic member 7 moving with the shaft core 3. The magnetic member 7 can rotate relative to the shaft core 3 during at least part of the process of moving with the shaft core 3. The magnetic member 7 can rotate around an axis.

[0164] like Figure 5-8 , 11, 12, 15 shown in the guide member 91 is a guide ring, the guide ring is provided with a guide block 92 or a guide groove 93.

Compared with the prior art, the magnetic member 7 in the shaft core 3 can rotate relative to the shaft core 3, so that the magnetic member 7 can rotate relative to the shaft core 3 during the pressing and moving process, which changes the way in which the magnetic member 7 in the key can only move toward the magnetic sensor 11 with the movement of the shaft core 3, so that when the key is executing the signal input process, the magnetic field change process sensed by the magnetic sensor 11 is smoother and more uniform, so that the induction sensitivity of the magnetic sensor 11 during the key input process of the keyboard is increased, which can improve the induction sensitivity of the key, and further improve the input stability of the keyboard.

[0171] Furthermore, the magnetic member 7 can rotate around an axis.
