Description

Technical Field

[0001] This utility model relates to the field of push-button switch technology, and in particular to a Hall magnetic levitation hot-swappable encoder. Background Technology

[0002] The keyboard is the most commonly used and primary input device. It allows users to input English letters, Chinese characters, numbers, punctuation marks, and other symbols into a computer, thus issuing commands and inputting data. Currently, the most common keyboards on the market include mechanical switch keyboards and magnetic switch keyboards. Mechanical switch keyboards offer a better feel and longer lifespan, while magnetic switch keyboards offer faster response and more flexible operation. These switches generally only have the function of outputting a pressed signal. For keyboards requiring different functions, additional functional structures need to be installed, such as a rotating encoder for adjusting volume. Due to structural differences, these encoders cannot be interchanged with mechanical or magnetic switches on the keyboard and require separate installation, which cannot meet the needs of users in different situations.

[0003] Furthermore, most encoders on the market are of the grating structure, which counts by blocking light through a wheel with spokes. These spokes are also the source of the tactile feedback of the grating roller. A small wire is used to hold the spokes in place; as the roller rotates, it scrapes against the wire, creating the tactile feedback. When the button is pressed, a small lever pulls the wire away from the spokes, allowing them to roll freely. However, this method leads to internal wear over time, resulting in reduced accuracy at different positions, a poor feel, and the ingress of dust or moisture, all of which affect normal operation and are not conducive to long-term use. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this invention is to provide a Hall effect magnetic levitation hot-swappable encoder shaft. Utilizing the magnetic attraction of a permanent magnet to a ring rotor, the shaft exhibits a distinct tactile feedback during free rotation, effectively reducing the limitations on product performance and lifespan caused by mechanical wear, as well as the uneven feel after wear. Furthermore, it can be freely replaced with magnetic or mechanical shafts on the keyboard circuit board, catering to the needs of different users and avoiding the need to replace the entire keyboard. This Hall effect magnetic levitation hot-swappable encoder shaft structure also features both pressing and rotating operation modes for different functions, further satisfying diverse user needs.

[0005] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0006] A Hall magnetic levitation hot-swappable encoder shaft is characterized by comprising: a base, an upper cover disposed on the base, an operating member movably disposed between the base and the upper cover, and an annular rotor disposed on the operating member. The annular rotor is made of a magnetic material, and the outer ring wall of the annular rotor is provided with grooves at intervals. At least one permanent magnet is disposed in the base that is opposite to and non-contact with the grooves of the annular rotor, and the permanent magnet performs magnetic interference on the annular rotor.

[0007] As a further improvement of this utility model, the width of the permanent magnet is greater than the outer perimeter of the groove opening.

[0008] As a further improvement of this utility model, a movable groove is formed in the middle of the base for the operation member to move, and at least one magnetic mounting groove is formed on the side of the movable groove for the permanent magnet to be inserted, wherein the length of the permanent magnet is greater than the length of the magnetic mounting groove.

[0009] As a further improvement of this utility model, the operating component includes a shaft movably disposed between the base and the upper cover, a drive ring disposed on the lower outer side of the shaft, and the annular rotor disposed within the drive ring.

[0010] As a further improvement of this utility model, it also includes a axial circuit board disposed at the lower part of the base and a Hall element disposed on the axial circuit board, and a sensing magnet directly opposite the Hall element is embedded at the lower end of the shaft.

[0011] As a further improvement of this utility model, it also includes a push switch disposed on the shaft circuit board and located below the shaft body and electrically connected to the shaft circuit board, a push groove is formed between the drive ring and the upper cover for the shaft body to move up and down, and a push clearance groove is formed on the inner lower surface of the base to accommodate the push switch.

[0012] As a further improvement of this utility model, it also includes a keyboard circuit board, and the base is disposed on the keyboard circuit board; the lower end surface of the circuit board is provided with at least one pressing spring pin extending downward and electrically connected to the pressing switch, and at least one magnetic spring pin extending downward and electrically connected to the Hall element; the keyboard circuit board is provided with at least one pressing contact for the pressing spring pin to abut and conduct, and at least one magnetic contact for the magnetic spring pin to abut and conduct.

[0013] As a further improvement of this utility model, the lower end of the shaft is generally rectangular, and the middle part of the driving ring has a shaft mounting port that is generally rectangular and matches the lower end of the shaft.

[0014] As a further improvement of this utility model, the lower part of the shaft body is formed with an outwardly protruding limiting ring platform that moves within the pressing groove, and the diameter of the limiting ring platform is larger than the diameter of the shaft mounting opening.

[0015] As a further improvement of this utility model, at least one magnetic limiting baffle is formed on the inner lower end surface of the base, which extends upward and presses and limits the permanent magnet, and a pressing limiting ring is formed on the inner lower bottom surface of the base, which extends upward and presses and limits the driving ring.

[0016] The beneficial effects of this utility model are as follows:

[0017] By configuring the shaft of the Ben Hall magnetic levitation hot-swappable encoder as including a base, a top cover disposed on the base, an operating member movably disposed between the base and the top cover, and an annular rotor disposed on the operating member, the annular rotor being made of a magnetic material, with grooves spaced apart on the outer ring wall of the annular rotor, and at least one permanent magnet disposed in the base that is opposite to but not in contact with the grooves of the annular rotor, the permanent magnet magnetically interferes with the annular rotor, and the permanent magnet magnetically attracts the annular rotor, when the operating member is driven to rotate by an external force, the operating member simultaneously drives the annular rotor disposed thereon. The rotating rotor exhibits a strong attraction when the permanent magnet is positioned opposite the groove on the annular rotor. Conversely, when the permanent magnet is directly opposite the groove on the annular rotor, the attraction weakens. This intermittent structure creates distinct tactile feedback, enhancing the user experience of the BenHall magnetic levitation hot-swappable encoder shaft. Furthermore, the elimination of mechanical structures effectively reduces product lifespan limitations caused by mechanical wear and uneven tactile feedback after wear. The simple structure of the BenHall magnetic levitation hot-swappable encoder shaft facilitates assembly and effectively meets the demands of modern manufacturing. It can also be freely interchanged with magnetic and mechanical shafts on the keyboard circuit board, catering to different user needs and avoiding the need to replace the entire keyboard. Moreover, the BenHall magnetic levitation hot-swappable encoder shaft structure offers both pressing and rotating operation modes for different functions, further satisfying diverse user requirements.

Detailed Implementation

[0030] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0031] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Please refer to Figures 1 to 10This utility model embodiment provides a Hall magnetic levitation hot-swappable encoder shaft 031, including a base 01, an upper cover 02 disposed on the base 01, an operating member 03 movably disposed between the base 01 and the upper cover 02, and an annular rotor 04 disposed on the operating member 03. The annular rotor 04 is an annular rotor 04 made of magnetic material. The outer ring wall of the annular rotor 04 is provided with grooves 041 at intervals. At least one permanent magnet 05 is disposed in the base 01, which is opposite to and non-contact with the grooves 041 of the annular rotor 04. The permanent magnet 05 performs magnetic interference on the annular rotor 04. The permanent magnet 05 magnetically attracts the annular rotor 04. When the operating component 03 is rotated by an external force, it simultaneously drives the annular rotor 04 mounted on it to rotate. When the permanent magnet 05 is in a position where there is no groove 041 on the annular rotor 04, the annular rotor 04 experiences a strong attraction force from the permanent magnet 05. When the permanent magnet 05 is directly opposite the groove 041 on the annular rotor 04, the attraction force is weaker. This spaced structure creates a distinct tactile feedback, improving the user experience of the BenHall magnetic levitation hot-swappable encoder shaft. Furthermore, the elimination of mechanical structures effectively reduces the problems of limited product lifespan due to mechanical wear and uneven tactile feedback after wear. The BenHall magnetic levitation hot-swappable encoder shaft has a simple structure, facilitating assembly and effectively meeting the needs of modern production. It can also be freely interchanged with magnetic shafts, mechanical shafts, etc., on the keyboard's circuit board, satisfying the needs of different users and avoiding the need to replace the entire keyboard. Furthermore, the BenHall magnetic levitation hot-swappable encoder shaft structure has two different usage modes: pressing and rotating, to achieve different functions and further meet the needs of different users.

[0035] Preferably, the annular rotor 04 is made of silicon steel, which, while maintaining the rigidity of the annular rotor 04, has high permeability and low hysteresis characteristics, as well as good resistivity and conductivity. It can effectively reduce hysteresis loss and eddy current loss when magnetic flux passes through it, improve the energy efficiency of the equipment, effectively ensure the magnetic adsorption of the permanent magnet 05 to the annular rotor 04, and effectively ensure the tactile feel of the Ben Hall magnetic levitation hot-swappable encoder shaft.

[0036] To further ensure the user experience of the Ben Hall magnetic levitation hot-swappable encoder shaft 031, such as Figures 3 to 4 , Figure 7 and Figure 9 As shown, the width of the permanent magnet 05 is greater than the outer perimeter of the opening of the groove 041, which makes the magnetic attraction of the permanent magnet 05 to the annular rotor 04 more distinct and effectively ensures the segmented feel of the Ben Hall magnetic levitation hot-swappable encoder shaft.

[0037] Regarding the specific manner in which the operating element 03 and the annular rotor 04 are disposed on the base 01, as follows: Figures 3 to 4 , Figure 6 , Figures 8 to 10 As shown, a movable groove 011 is formed in the middle of the base 01 for the operation member 03 to move. At least one magnetic mounting groove 012 is formed on the side of the movable groove 011 for the permanent magnet 05 to be placed. The operation member 03 is driven by an external force to rotate and move up and down in the movable groove 011, thereby triggering different signal transmission modes of the Ben Hall magnetic levitation hot-swappable encoder shaft. The permanent magnet 05 is installed in the magnetic mounting groove 012 to fix the permanent magnet 05.

[0038] Preferred, such as Figures 3 to 4 , Figure 6 , Figures 8 to 10 As shown, the length of the permanent magnet 05 is greater than the length of the magnetic mounting groove 012, causing the end of the permanent magnet 05 facing the annular rotor 04 to protrude outside the magnetic mounting groove 012 and be closer to the annular rotor 04 inside the operating member 03. This makes the magnetic attraction force of the permanent magnet 05 to the annular rotor 04 more obvious, further improving the feel of the shaft of this magnetic levitation hot-swappable encoder. After the permanent magnet 05 protrudes outside the magnetic mounting groove 012, a certain distance is maintained between it and the operating member 03, effectively preventing the permanent magnet 05 from directly contacting the operating member 03 and being damaged, or from detaching and shifting from the magnetic mounting groove 012. The contactless structure reduces wear, ensures the normal operation of the Ben Hall magnetic levitation hot-swappable encoder shaft 031, and guarantees its service life. The distance between the permanent magnet 05 and the operating member 03 can be set according to actual conditions, so no specific limitation is made in this embodiment.

[0039] To prevent the permanent magnet 05 from shifting during use, such as Figure 6 and Figure 10 As shown, at least one magnetic limiting baffle 014 is formed on the lower inner surface of the base 01, which extends upward and presses and limits the permanent magnet 05. By protruding the magnetic limiting baffle 014 upward, the lower end of the permanent magnet 05 after being pulled out of the magnetic mounting groove 012 is blocked, and the upper end of the permanent magnet 05 is pressed down in conjunction with the upper cover 02, which effectively prevents the permanent magnet 05 from being driven to shift and fall off during use, and ensures the normal use of the Ben Hall magnetic levitation hot-swappable encoder shaft.

[0040] Preferred, such as Figures 4 to 5 , Figures 7 to 10As shown, there are four groups of permanent magnets 05, evenly distributed on the side of the movable groove 011. This ensures that the magnetic attraction force on the annular rotor 04 is uniform when it rotates, resulting in a uniform overall feel and improved user experience. The specific dimensions of the grooves 041 can be set according to the specific dimensions of the permanent magnets 05. This ensures that when the annular rotor 04 rotates, each permanent magnet 05 is simultaneously positioned directly opposite a groove 041, or that none of the permanent magnets 05 are simultaneously positioned directly opposite a groove 041. This prevents uneven magnetic attraction forces on the annular rotor 04, which could lead to a lack of distinct tactile feedback and effectively guarantees the user experience of the Ben Hall magnetic levitation hot-swappable encoder shaft.

[0041] Regarding the specific structural configuration of the control element 03, as follows: Figures 4 to 8 As shown, the control element 03 includes a shaft 031 movably disposed between the base 01 and the upper cover 02, and a drive ring 032 disposed on the lower outer side of the shaft 031. The annular rotor 04 is disposed within the drive ring 032. The shaft 031 is used to be pressed and rotated by external force, thereby realizing different signal outputs. The shaft 031 drives the drive ring 032 disposed thereon and the wake-up rotor embedded in the drive ring 032 to rotate, thereby realizing that when the annular rotor 04 is driven to rotate, it is magnetically attracted by the permanent magnet 05, thus producing a segmented tactile feel and improving the user experience.

[0042] Regarding the specific method of signal output when the shaft of the Ben Hall magnetic levitation hot-swappable encoder is rotated by an external force, such as... Figures 4 to 10 As shown, the Hall magnetic levitation hot-swappable encoder shaft also includes a shaft circuit board 06 disposed at the lower part of the base 01 and a Hall element 07 disposed on the shaft circuit board 06. A sensing magnet 08 is embedded at the lower end of the shaft 031, directly opposite the Hall element 07. When the shaft 031 is rotated by an external force, it drives the sensing magnet 08 disposed at its lower end to rotate. The Hall element 07 on the shaft circuit board 06 senses the rotation of the sensing magnet 08, thereby realizing the output of a rotation signal and completing the corresponding function (such as rotating to adjust the volume).

[0043] Preferred, such as Figure 6 As shown, the shaft circuit board 06 is embedded in the lower part of the base 01 and is flush with the bottom of the base 01, thereby effectively reducing the overall volume of the Ben Hall magnetic levitation hot-swappable encoder shaft, meeting the usage needs of different people for shaft height, and further improving the practicality of the Ben Hall magnetic levitation hot-swappable encoder shaft.

[0044] The specific method by which the shaft of the Ben Hall magnetic levitation hot-swappable encoder is pressed by an external force to achieve signal output is as follows: Figures 4 to 10As shown, the Ben Hall magnetic levitation hot-swappable encoder shaft also includes a push switch 09 disposed on the shaft circuit board 06 and located below the shaft 031 and electrically connected to the shaft circuit board 06. A push groove 10 is formed between the drive ring 032 and the upper cover 02 to allow the shaft 031 to move up and down. A push clearance groove 013 is formed on the inner lower surface of the base 01 to accommodate the push switch 09. When the shaft 031 is pressed, the upper part of the shaft 031 moves down to the lower part between the push grooves 10, and drives the induction magnet 08 to press the push switch 09, causing the push switch 09 to start and transmit a signal outward, thereby realizing the output of the limit number and completing the corresponding function (such as starting / stopping a function). After the shaft 031 is released from the press, the push switch 09 drives the shaft 031 to reset, waiting for the next use. Regarding the specific configuration of the push switch 09, the push switch 09 is a trigger switch. The trigger switch can sense extremely slight external force touch, and can quickly trigger the action even with slight external force. The internal precision structure ensures accurate trigger response, and the price is low. It reduces costs while ensuring performance, which is beneficial to production.

[0045] Preferred, such as Figures 4 to 10 As shown, the push switch 09 is disposed on the upper end surface of the shaft circuit board 06, and the Hall element 07 is disposed on the lower end surface of the shaft circuit board 06. This makes reasonable use of the position of the shaft circuit board 06, reduces the overall volume of the Hall magnetic levitation hot-swappable encoder shaft, meets the usage needs of different people for shaft height, and further improves the practicality of the Hall magnetic levitation hot-swappable encoder shaft.

[0046] Regarding the specific method of transmitting signals from the shaft of the Ben Hall magnetic levitation hot-swappable encoder to the outside, such as Figures 4 to 7As shown, the Hall magnetic levitation hot-swappable encoder shaft also includes a keyboard circuit board 11, and the base 01 is disposed on the keyboard circuit board 11; the lower end surface of the shaft circuit board 06 is provided with at least one pressing spring pin 061 extending downward and electrically connected to the pressing switch 09, and at least one magnetic spring pin 062 extending downward and electrically connected to the Hall element 07; the keyboard circuit board 11 is provided with at least one pressing contact 1 for the pressing spring pin 061 to abut and conduct. 11. The base 01 is detachably fixed to the keyboard circuit board 11 when the Hall effect magnetic levitation hot-swappable encoder shaft is mounted on the keyboard circuit board 11, and the pressing spring pin 061 on the shaft circuit board 06 presses against the pressing contact 111 on the keyboard limiting plate. Simultaneously, the magnetic spring pin 062 on the shaft circuit board 06 presses against the magnetic contact 112 on the keyboard limiting plate. When an external force rotates the shaft 031, the Hall element 07 on the shaft circuit board 06 senses the sensing magnet 08 on the shaft 031 and transmits the sensed information through the shaft circuit board 06 to the magnetic spring pin 062, which then transmits it to the magnetic contact 112, thereby reaching the keyboard limiting plate and realizing signal transmission. When an external force presses the axis 031, the push switch 09 on the axis circuit board 06 is triggered by the axis 031, and the trigger information is transmitted through the axis circuit board 06 to the push spring pin 061, which then transmits it to the push contact 111, thereby reaching the keyboard limit plate and realizing signal transmission. Figures 2 to 3 As shown, by setting the pressing spring pin 061 and magnetic spring pin 062 on the axis circuit board 06, and setting the pressing contact 111 and magnetic contact 112 on the keyboard circuit board 11, the original mounting hole structure and corresponding conductive structure of the mechanical or magnetic shaft on the keyboard circuit board 11 do not need to be modified. Only the pressing contact 111 and magnetic contact 112 need to be added to its surface. This allows the Hall magnetic levitation hot-swappable encoder shaft 031 to be interchanged with the mechanical or magnetic shaft on the keyboard circuit board 11, meeting the needs of different users and avoiding the need to replace the entire keyboard, thus facilitating user experience. The number of pressing spring pins 061 and magnetic spring pins 062 can be set according to actual conditions. For example, the pressing spring pins 061 can be set to 2 groups, and the magnetic spring pins 062 can be set to 3 to 5 groups. These can be adjusted according to the pins of different Hall elements, so no specific limitation is made in this embodiment.

[0047] Preferred, such as Figures 4 to 6As shown, a fixing plate is also provided at the lower end of the shaft circuit board 06. A support foot is formed at the lower end of the base 01, which passes through the fixing plate. The pressing spring pin 061 and the magnetic spring pin 062 pass through the fixing plate and press against the keyboard circuit board 11. The fixing plate is fixed in the lower part of the base 01 by the support foot, thereby fixing the shaft circuit board 06 in the base 01. A clearance groove for the Hall element 07 and clearance holes for the pressing spring pin 061 and the magnetic spring pin 062 are formed in the middle of the fixing plate, thereby effectively saving the space of the Ben Hall magnetic levitation hot-swappable encoder, meeting the usage needs of different people for shaft height, and further improving the practicality of the Ben Hall magnetic levitation hot-swappable encoder shaft.

[0048] The specific method by which the shaft 031 drives the drive ring 032 mounted on it to rotate is as follows: Figures 4 to 5 As shown, the lower end of the shaft 031 is generally rectangular, and the middle of the driving ring 032 has a rectangular mounting port 0321 that matches the lower end of the shaft 031. By setting the shaft 031 and the mounting port 0321 to a rectangular structure, the shaft 031 can better drive the driving ring 032 when it rotates, so that the annular rotor 04 inside the driving ring 032 rotates synchronously and produces a segmented feel under the magnetic attraction force of the permanent magnet 05. Its rectangular structure is easier to drive than a circular structure, improving the efficiency and accuracy of the shaft 031 and ensuring the feel of the Ben Hall magnetic levitation hot-swappable encoder shaft.

[0049] Preferred, such as Figures 4 to 8 As shown, to prevent the shaft 031 from excessively downward movement when pressed, which could damage the push-button switch 09, a limiting ring platform 0311 is formed at the lower part of the shaft 031, protruding outward and moving within the pressing groove 10. The diameter of the limiting ring platform 0311 is larger than the diameter of the shaft mounting opening 0321. The limiting ring platform 0311 is driven by the shaft 031 to move up and down within the pressing groove 10, and is limited by the height of the pressing groove 10. Furthermore, the larger diameter of the limiting ring platform 0311 prevents it from penetrating into the shaft mounting opening 0321 when pressed down, further limiting the travel of the limiting ring platform 0311, improving the accuracy of the shaft 031's movement, avoiding excessive downward movement of the shaft 031 when pressed, which could damage the push-button switch 09, and ensuring the service life of the Ben Hall magnetic levitation hot-swappable encoder shaft.

[0050] To prevent the drive ring 032 from shifting downwards and accidentally pressing the switch 09, such as... Figure 6 as well as Figure 10As shown, a pressing and limiting ring 015 is formed on the inner lower surface of the base 01, extending upward and pressing and limiting the drive ring 032. The drive ring 032 presses against the pressing and limiting ring 015, thereby effectively preventing the drive ring 032 from being driven downward when the shaft 031 moves downward, which would cause the switch 09 to be accidentally pressed, thus ensuring the accuracy of the shaft drive of the Ben Hall magnetic levitation hot-swappable encoder.

[0051] It should be noted that the Hall magnetic levitation hot-swappable encoder shaft disclosed in this utility model is an improvement on the specific structure, but the specific control method is not the innovation of this utility model. The permanent magnet, Hall element, trigger switch, spring pin, circuit board, and other components involved in this utility model can be general standard parts or components known to those skilled in the art. Their structure, principle, and control method are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0052] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
