Description

Technical Field

[0001] This utility model relates to the field of encoder technology, and in particular to a Hall magnetic levitation mouse encoder. Background Technology

[0002] As an important component of the mouse, the performance and user experience of the mouse wheel have a significant impact on the overall evaluation of the mouse.

[0003] Most existing undamped scroll wheels are optical encoder wheels, which count the number of light rays by blocking light through a wheel with spokes. These spokes are also the source of the scroll wheel's tactile feedback. A small wire is used to hold the spokes in place; as the scroll wheel rotates, it scrapes against the wire, creating the tactile feedback. When the button is pressed, a small lever pushes the wire away from the spokes, allowing the spokes to roll freely. However, this method leads to internal wear over time, and dust or moisture can easily enter, affecting normal operation and reducing the mouse's longevity.

[0004] There are also rollers on the market that utilize the properties of electromagnets. The inner ring of the roller is lined with a ferromagnetic material, and inside the roller is a pair of magnets, one permanent magnet and the other an electromagnet. When the electromagnet is energized, its magnetic field strength is similar to that of the permanent magnet, but its polarity can be adjusted by controlling the direction of the current. In segmented scrolling mode, the electromagnet and the permanent magnet have the same polarity, effectively acting as a single large magnet. At both ends of the electromagnet and the permanent magnet are small pieces of ferromagnetic material with a spiked structure similar to the inner ring of the roller. When these two spikes approach each other, the magnetic force creates a segmented "segment." When switched to undamped mode, the current in the electromagnet changes direction, and the polarity of the electromagnet and the permanent magnet is opposite. In this mode, the magnetic field lines are confined to the core of the roller, exerting no magnetic force on the outer ferromagnetic ring, allowing the outer ring to roll freely.

[0005] However, because this existing technology involves permanent magnets and electromagnets, its internal structure is extremely complex, and the lifespan of electronic components can easily affect the overall performance and lifespan of the product. Therefore, the focus of this invention is on how to simplify the components and construct a completely new structural design to ensure that the mouse scroll wheel provides a tactile feedback that provides a good user experience when rotating, while reducing costs and increasing the product's lifespan. Utility Model Content

[0006] To address the aforementioned shortcomings, the purpose of this utility model is to provide a Hall magnetic levitation mouse encoder. This encoder utilizes the magnetic attraction of a permanent magnet to a ring rotor, enabling the mouse wheel to exhibit distinct tactile feedback during free rotation. This effectively avoids the problem of limited product performance and lifespan caused by wear and tear of electronic components or machinery. Furthermore, this Hall magnetic levitation mouse encoder features a simple structure, facilitating assembly and effectively meeting the development needs of modern production.

[0007] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0008] A Hall effect magnetic levitation mouse encoder includes a mounting base disposed inside the mouse, a rotating base rotatably disposed within the mounting base and connected to the mouse's scroll wheel, and an annular rotor disposed within the rotating base and driven by the rotating base. The annular rotor is made of a magnetic material, and the outer ring wall of the annular rotor is provided with grooves at intervals. The mounting base is provided with at least one permanent magnet that is opposite to and non-contacting with the grooves of the annular rotor, and the permanent magnet performs magnetic interference on the annular rotor.

[0009] As a further improvement of this utility model, the diameter of the permanent magnet is greater than the outer perimeter of the groove opening.

[0010] As a further improvement of this utility model, a rotating groove is formed in the middle of the mounting base for the rotating base to rotate, and at least one magnet mounting groove is formed on the side of the rotating groove for the permanent magnet to be placed.

[0011] As a further improvement of this utility model, the permanent magnet is cylindrical in shape.

[0012] As a further improvement of this utility model, an arc-shaped clearance groove matching the permanent magnet is formed on the side wall of the magnet mounting groove away from the rotating seat.

[0013] As a further improvement of this utility model, the number of permanent magnets is two sets, and the two sets of permanent magnets are symmetrically arranged in the mounting base and located on both sides of the rotating base. They are a first permanent magnet arranged in the mounting base and located on the left side of the rotating base, and a second permanent magnet arranged in the mounting base and located on the right side of the rotating base.

[0014] As a further improvement of this utility model, a first magnet mounting groove for inserting the first permanent magnet and a second magnet mounting groove symmetrical to the first magnet mounting groove for inserting the second permanent magnet are formed on the side of the rotating groove.

[0015] As a further improvement of this utility model, the rotating seat includes a rotating part placed in the rotating groove and surrounding the annular rotor, a roller connecting part formed on the upper part of the rotating part and protruding upward to connect with the mouse roller, and a Hall sensing part formed on the lower part of the rotating part and protruding downward, wherein a sensing magnet is embedded in the Hall sensing part.

[0016] As a further improvement of this utility model, the mounting base includes a body for the rotating seat and the permanent magnet to be placed and operated, and an upper cover covering the body.

[0017] As a further improvement of this utility model, it also includes a circuit board disposed at the lower end of the mounting base, and a Hall element matching the inductive magnet is disposed on the lower end surface of the circuit board.

[0018] The beneficial effects of this utility model are as follows:

[0019] The Ben Hall magnetic levitation mouse encoder is configured to include a mounting base inside the mouse, a rotating base rotatably mounted within the mounting base and connected to the mouse scroll wheel, and an annular rotor mounted within the rotating base and driven by the rotating base. The annular rotor is made of a magnetic material, and its outer ring wall is provided with grooves spaced apart. The mounting base has at least one permanent magnet 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 magnetically attracts it. When the mouse scroll wheel rotates, the rotating base connected to the mouse scroll wheel... The ring rotor rotates, and when it rotates to a position where the permanent magnet is not in the groove on the ring rotor, the ring rotor is strongly attracted by the permanent magnet. When it rotates to a position where the permanent magnet is directly in the groove on the ring rotor, the attraction force on the ring rotor is weaker. The spaced structure creates a distinct sense of segmentation, improving the user experience of the BenHall magnetic levitation mouse encoder. Furthermore, it eliminates the need for mechanical structures and electromagnetic components, effectively avoiding the problem of limited product performance and lifespan caused by wear and tear of electronic components or machinery. In addition, the BenHall magnetic levitation mouse encoder has a simple structural component, which is easy to assemble and effectively meets the development needs of modern production.

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 8 This utility model provides a Hall magnetic levitation mouse encoder, including a mounting base 1 disposed inside the mouse, a rotating base 2 rotatably disposed inside the mounting base 1 and connected to the mouse scroll wheel, and an annular rotor 3 disposed inside the rotating base 2 and driven by the rotating base 2. The annular rotor 3 is made of magnetic material, and the outer ring wall of the annular rotor 3 is provided with grooves 31 at intervals. The mounting base 1 is provided with at least one permanent magnet 4 that is opposite to and non-contact with the grooves 31 of the annular rotor 3, and the permanent magnet 4 performs magnetic interference on the annular rotor 3.

[0035] The permanent magnet 4 magnetically attracts the annular rotor 3. When the scroll wheel on the mouse rotates, the rotating seat 2 connected to the scroll wheel drives the annular rotor 3 to rotate. When the permanent magnet 4 is in a position where there is no groove 31 on the annular rotor 3, the annular rotor 3 is strongly attracted by the permanent magnet 4. When the permanent magnet 4 is directly opposite the groove 31 on the annular rotor 3, the attraction force on the annular rotor 3 is weaker. The spaced structure achieves a distinct sense of segmentation, improving the user experience of the BenHall magnetic levitation mouse encoder. Furthermore, it eliminates the need for mechanical structures and electromagnetic components, effectively avoiding the problem of limited product performance and lifespan caused by wear and tear of electronic components or machinery. The BenHall magnetic levitation mouse encoder has a simple structural component, which is easy to assemble and effectively meets the development needs of modern production. By setting the permanent magnet 4 to a structure in which it does not directly contact the annular rotor 3 through the spaced rotating seat 2, and by confining the permanent magnet 4 within the mounting base 1, the permanent magnet 4 is unable to move due to the travel limitation of the mounting base 1 when the rotating seat 2 drives the annular rotor 3 to rotate. This allows the permanent magnet 4 to be very close to the rotating seat 2 under the restriction of the mounting base 1, thereby achieving higher magnetic adsorption force and better feel, while also ensuring the normal operation of the Ben Hall magnetic levitation mouse encoder. This effectively avoids the problem of the annular rotor 3 being unable to rotate due to the permanent magnet 4 being directly adsorbed onto it.

[0036] Preferably, the annular rotor 3 is a silicon steel annular rotor, which, while maintaining the hardness of the annular rotor 3, has high magnetic 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 4 to the annular rotor 3, and effectively ensure the tactile feedback of the Ben Hall magnetic levitation mouse encoder.

[0037] To further ensure the ergonomic feel of the Ben Hall magnetic levitation mouse encoder, such as Figures 2 to 3 , Figure 6 , Figure 8 As shown, the diameter of the permanent magnet 4 is larger than the outer perimeter of the opening of the groove 31, so that the magnetic attraction force of the permanent magnet 4 on the annular rotor 3 is more distinct, effectively ensuring the segmented feel of the Ben Hall magnetic levitation mouse encoder.

[0038] Regarding the specific manner in which the rotating seat 2 rotates within the mounting base 1, as follows: Figures 3 to 6 as well as Figure 8As shown, a rotating groove 111 is formed in the middle of the mounting base 1 for the rotating base 2 to rotate. At least one magnet mounting groove 112 is formed on the side of the rotating groove 111 for the permanent magnet 4 to be placed. The rotating base 2 rotates in the rotating groove 111 and its stroke is limited by the rotating groove 111, thereby effectively preventing the rotating base 2 from falling or shifting during the process driven by the mouse wheel. By setting the magnet mounting groove 112 on the side of the rotating groove 111, the permanent magnet 4 is placed in the magnet mounting groove 112 and is limited by the magnet mounting groove. One end of the permanent magnet 4 can be very close to or pressed against the outside of the rotating base 2 in the rotating groove 111, thereby achieving better magnetic adsorption feel without displacement and effectively ensuring the tactile feel of the Ben Hall magnetic levitation mouse encoder.

[0039] Preferred, such as Figures 3 to 6 as well as Figure 8 As shown, the permanent magnet 4 is cylindrical in shape. One end of it is limited by the rotating seat 2, and the other three ends are limited by the magnet mounting groove 112. This allows the permanent magnet 4 to magnetically attract the annular rotor 3 even when it is very close to the rotating seat 2 and is driven to rotate by the rotating seat 2. Furthermore, the synchronous rotation reduces wear on itself and ensures the service life of the Ben Hall magnetic levitation mouse encoder.

[0040] Preferred, such as Figures 3 to 6 as well as Figure 8 As shown, in order to better limit the permanent magnet 4 in the magnet mounting groove 112, an arc-shaped clearance groove 113 matching the permanent magnet 4 is formed on the side wall of the magnet mounting groove 112 away from the rotating seat 2. Its arc-shaped structure is more in line with the cylindrical structure of the permanent magnet 4, and it makes way for the end of the permanent magnet 4 away from the rotating seat 2, which is conducive to more precise limiting of the permanent magnet 4 and makes the fit between the components tight.

[0041] Regarding the specific structural configuration of the permanent magnet 4, as follows: Figures 3 to 6 as well as Figure 8 As shown, there are two sets of permanent magnets 4, which are symmetrically arranged in the mounting base 1 and on both sides of the rotating base 2. They are a first permanent magnet 41 located in the mounting base 1 and on the left side of the rotating base 2, and a second permanent magnet 42 located in the mounting base 1 and on the right side of the rotating base 2. This makes the magnetic attraction force on both sides of the annular rotor 3 uniform, providing the user with a more stable and distinct tactile feedback, thereby improving the user experience of the Ben Hall magnetic levitation mouse encoder.

[0042] The distance and specific dimensions between the grooves 31 can be set according to the specific dimensions of the permanent magnets, thereby ensuring that while the annular rotor 3 is rotating, the first permanent magnet 41 and the second permanent magnet 42 are simultaneously positioned directly opposite the grooves 31, or neither the first permanent magnet 41 nor the second permanent magnet 42 are simultaneously positioned directly opposite the grooves 31. This prevents uneven magnetic attraction on the annular rotor 3 from causing a lack of distinct tactile feedback, effectively ensuring the user experience of the Ben Hall magnetic levitation mouse encoder.

[0043] The specific manner in which the first permanent magnet 41 and the second permanent magnet 42 are respectively disposed on the mounting base 1 is as follows: Figures 3 to 6 as well as Figure 8 As shown, a first magnet mounting groove 1121 for inserting the first permanent magnet 41 and a second magnet mounting groove 1122 symmetrical to the first magnet mounting groove 1121 for inserting the second permanent magnet 42 are formed on the side of the rotating groove 111. The first permanent magnet 41 is inserted into the first magnet mounting groove 1121 and the second permanent magnet 42 is inserted into the second magnet mounting groove 1122, thereby completing the installation of the first permanent magnet 41 and the second permanent magnet 42 respectively, ensuring the normal operation of the Hall magnetic levitation mouse encoder.

[0044] Preferred, such as Figures 3 to 6 as well as Figure 8 As shown, a first arc-shaped clearance groove 1131 matching the first permanent magnet 41 is formed on the side wall of the first magnet mounting groove 1121 away from the rotating seat 2, and a second arc-shaped clearance groove 1132 matching the second permanent magnet 42 is formed on the side wall of the second magnet mounting groove 1122 away from the rotating seat 2. The arc-shaped structure is more in line with the cylindrical structure of the first permanent magnet 41 and the second permanent magnet 42, and the clearance of the end of the first permanent magnet 41 and the second permanent magnet 42 away from the rotating seat 2 is provided, which is conducive to more precise positioning of the first permanent magnet 41 and the second permanent magnet 42, so that the components fit together tightly.

[0045] Regarding the specific structural configuration of the rotating seat 2, as follows: Figures 3 to 5 as well as Figure 8As shown, the rotating base 2 includes a rotating part 21 placed inside the rotating groove 111 and surrounding the annular rotor 3; a roller connecting part 22 formed on the upper part of the rotating part 21 and protruding upward to connect with the mouse scroll wheel; and a Hall sensor part 23 formed on the lower part of the rotating part 21 and protruding downward. A sensing magnet 5 is embedded in the Hall sensor part 23. The base also includes a circuit board 6 disposed at the lower end of the mounting base 1. A Hall element 7 is disposed on the circuit board 6 directly below the sensing magnet 5. The rotating part 21 rotates within the rotating groove 111, thereby being limited in its travel by the rotating groove 111 to prevent it from falling off or shifting, ensuring the normal operation of the Hall magnetic levitation mouse encoder. The roller connecting part 22 has a fixing hole in its middle for inserting a bearing. One end of the bearing is fixed in the fixing hole, and the other end is fixed to the middle of the mouse scroll wheel, effectively transmitting the rotation of the mouse scroll wheel to the Hall magnetic levitation mouse encoder, thereby achieving signal output. By providing a downwardly protruding structure at the lower end of the rotating part 21, while ensuring the rotation of the inductive magnet 5, the inductive magnet 5 is brought closer to the Hall element 7 on the lower circuit board 6. This allows the Hall element 7 to more accurately sense the rotation of the inductive magnet 5, effectively transmitting the signal. Preferably, the Hall element 7 is located on the lower surface of the circuit board 6, effectively saving space on the upper surface of the circuit board 6, providing more space for the rotating seat 2 and other components to move, saving overall space and facilitating use.

[0046] Preferably, the sensing magnet 5 is also a permanent magnet, thereby effectively ensuring the service life of the Ben Hall magnetic levitation mouse encoder.

[0047] like Figures 1 to 3 as well as Figures 7 to 8 As shown, the circuit board 6 may be provided with an outwardly extending connecting plate. The connecting plate may be a long plate or multiple short plates. The circuit board may also be configured as an FPC board or other structures. It is soldered or plugged into the main circuit board of the mouse through the connecting plate to realize the conduction between the Ben Hall magnetic levitation mouse encoder and the main circuit board of the mouse. It can be configured according to the actual situation, so no specific limitation is made in this embodiment.

[0048] Regarding the specific structural configuration of the mounting base 1, as follows: Figures 1 to 4 as well as Figures 7 to 8As shown, the mounting base 1 includes a body 11 for the rotating seat 2 and the permanent magnet to be inserted and operated, and an upper cover 12 covering the body 11. The rotating groove 111, the magnet mounting groove 112, etc. are provided on the body 11. The upper cover 12 closes on the body 11, thereby limiting the upper ends of the rotating seat 2, the permanent magnet 4, etc., which are set in the rotating groove 111, effectively preventing the components from shifting or falling off during operation, and ensuring the normal use of the Ben Hall magnetic levitation mouse encoder. The upper cover 12 may be provided with mounting buckles, mounting plates, etc., to facilitate the overall fixation of the Ben Hall magnetic levitation mouse encoder.

[0049] It should be noted that the Hall magnetic levitation mouse encoder 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, 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 known to those skilled in the art through technical manuals or conventional experimental methods.

[0050] 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.
