Description

A flywheel structure with segmented design Technical Field

[0001] This utility model relates to the field of input technology, and in particular to a flywheel structure with segmented feedback. 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 grating scroll wheels, which count by blocking light through a wheel with spokes. These spokes are also the source of the scroll wheel's tactile feedback. Simply use a small wire to hold the spokes in place; as the scroll rotates, it scrapes against the wire, creating the tactile feedback. When the button is pressed, a small lever can push the wire away, disengaging it from the spokes, allowing the spokes to roll freely.

[0004] Over time, the internal structure of such rollers experiences wear. Therefore, rollers utilizing the properties of electromagnets have been developed. 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 energized, the electromagnet's 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 permanent magnet have the same polarity, effectively acting as a single large magnet. At both ends of the electromagnet and 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 feel. When switching to undamped mode, the current in the electromagnet reverses direction, and the polarity of the electromagnet and permanent magnet becomes opposite. In this mode, the magnetic field lines are confined to the roller core, exerting no magnetic force on the outer ferromagnetic ring, allowing the outer ring to roll freely.

[0005] However, existing technologies involve permanent magnets and electromagnets, resulting in exceptionally complex internal structures, high component and manufacturing costs, and the lifespan of electronic components that can significantly impact the overall performance and lifespan of the product. Therefore, this invention focuses on simplifying components and designing a novel structure to ensure the flywheel provides a satisfying tactile feedback during rotation, while simultaneously reducing costs and increasing product lifespan. Utility Model Content

[0006] To address the aforementioned shortcomings, the purpose of this utility model is to provide a flywheel structure with distinct segments. This structure eliminates the need for electromagnetic components, relying solely on the magnetic attraction of permanent magnets to the annular rotor to create a clear segmented effect during free rotation. This effectively avoids the performance and lifespan limitations caused by electronic components. Furthermore, this flywheel structure is simple, has low production costs, and effectively meets 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 segmented flywheel structure includes a support frame and a metal flywheel disposed on the support frame. The metal flywheel has several spaced slots arranged sequentially at intervals. A permanent magnet is disposed on the support frame in a direction extending into the metal flywheel body, which is opposite to and non-contact with the spaced slots of the metal flywheel. The permanent magnet performs magnetic interference on the metal sheet.

[0009] As a further improvement of this utility model, the width of the permanent magnet is less than or equal to the length of the side of the spacer slot.

[0010] As a further improvement of this utility model, the height of the permanent magnet is less than or equal to the height of the spacer slot.

[0011] As a further improvement of this utility model, the number of permanent magnets is two sets, namely a first permanent magnet disposed on the left side of one end of the support and a second permanent magnet disposed on the right side of one end of the support.

[0012] As a further improvement of this utility model, the permanent magnet is further divided into two sets: a third permanent magnet disposed on the left side of the other end of the support and a fourth permanent magnet disposed on the right side of the other end of the support. The four sets of permanent magnets are symmetrically disposed on the four corners of the support.

[0013] As a further improvement of this utility model, it also includes a first limiting member that is L-shaped and can be embedded in the bracket, a second limiting member that is L-shaped and can be embedded in the bracket, a third limiting member that is L-shaped and can be embedded in the bracket, and a fourth limiting member that is L-shaped and can be embedded in the bracket. The first limiting member has a first mounting groove formed in the middle for mounting the first permanent magnet, the second limiting member has a second mounting groove formed in the middle for mounting the second permanent magnet, the third limiting member has a third mounting groove formed in the middle for mounting the third permanent magnet, and the fourth limiting member has a fourth mounting groove formed in the middle for mounting the fourth permanent magnet.

[0014] As a further improvement of this utility model, the side of the bracket is formed with a first embedding groove that is L-shaped and for the first limiting member to be inserted, a second embedding groove that is L-shaped and for the second limiting member to be inserted, a third embedding groove that is L-shaped and for the third limiting member to be inserted, and a fourth embedding groove that is L-shaped and for the fourth limiting member to be inserted.

[0015] As a further improvement of this utility model, it also includes a first baffle plate covering the first embedding groove and blocking and limiting the rear ends of the first permanent magnet and the first limiting member, a second baffle plate covering the second embedding groove and blocking and limiting the rear ends of the second permanent magnet and the second limiting member, a third baffle plate covering the third embedding groove and blocking and limiting the rear ends of the third permanent magnet and the third limiting member, and a fourth baffle plate covering the fourth embedding groove and blocking and limiting the rear ends of the fourth permanent magnet and the fourth limiting member.

[0016] As a further improvement of this utility model, a first fixing block that can be embedded in a bracket is formed below the first baffle, and a first fixing groove for the first fixing block to be embedded is formed on the lower part of one side of the bracket; a second fixing block that can be embedded in a bracket is formed below the second baffle, and a second fixing groove for the second fixing block to be embedded is formed on the lower part of one side of the bracket; a third fixing block that can be embedded in a bracket is formed below the third baffle, and a third fixing groove for the third fixing block to be embedded is formed on the lower part of the other side of the bracket; a fourth fixing block that can be embedded in a bracket is formed below the fourth baffle, and a fourth fixing groove for the fourth fixing block to be embedded is formed on the lower part of the other side of the bracket.

[0017] As a further improvement of this utility model, a first guide limiting block is formed on the upper part of one side of the bracket, which abuts against the upper surface of the first baffle and a second guide limiting block is formed on the upper surface of the second baffle. A third guide limiting block is formed on the other side of the bracket, which abuts against the upper surface of the third baffle and a fourth guide limiting block is formed on the upper surface of the fourth baffle. A first inclined guide surface is formed on the upper surface of the first guide limiting block, which extends inclinedly outward and downward from the metal flywheel. A second inclined guide surface is formed on the upper surface of the second guide limiting block, which extends inclinedly outward and downward from the metal flywheel. A third inclined guide surface is formed on the upper surface of the third guide limiting block, which extends inclinedly outward and downward from the metal flywheel. A fourth inclined guide surface is formed on the upper surface of the fourth guide limiting block, which extends inclinedly outward and downward from the metal flywheel.

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

[0019] This flywheel structure includes a support frame and a metal flywheel mounted on the support frame. The metal flywheel has several spaced-apart slots. A permanent magnet, positioned on the support frame extending into the flywheel body, is opposite to but not in contact with the spaced-apart slots of the metal flywheel. The permanent magnet magnetically interferes with the metal flywheel. The absence of direct contact between the permanent magnet and the metal flywheel effectively prevents the flywheel from becoming stuck due to magnetic attraction. The permanent magnet magnetically attracts the metal flywheel without contact. When the flywheel is rotated, the attraction is weak when the permanent magnet is directly opposite a spaced-apart slot, and even weaker when the permanent magnet is directly opposite a position without spaced-apart slots. This spacing creates a distinct, segmented feel, and eliminates the need for electromagnetic components, effectively avoiding the performance and lifespan limitations caused by electronic components. Furthermore, by designing the flywheel as metal, the tactile feedback can be achieved simply by adding a permanent magnet to a standard flywheel structure. The entire flywheel structure is simple, and the permanent magnet and other components are inexpensive, reducing production costs and effectively meeting the demands of modern manufacturing. By placing the permanent magnet on the support and directing it towards the metal flywheel, the permanent magnet is brought closer to the metal flywheel, resulting in more precise and agile magnetic interference, further ensuring the tactile feedback of this flywheel structure.

[0029] 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] Referring to Figures 1 to 7, this embodiment of the utility model provides a flywheel structure with a segmented feel, including a bracket 01. The structure is characterized by further including a metal flywheel 02 disposed on the bracket 01. The metal flywheel 02 has several spacer slots 021 arranged sequentially at intervals. A permanent magnet 03 is disposed on the bracket 01 extending into the body of the metal flywheel 02, opposite to but not in contact with the spacer slots 021 of the metal flywheel 02. The permanent magnet 03 performs magnetic interference on the metal sheet.

[0035] The permanent magnet 03 and the metal flywheel 02 do not directly contact each other, effectively preventing the metal flywheel 02 from becoming unable to rotate due to the permanent magnet 03 magnetically adsorbing it. The permanent magnet 03 magnetically attracts the metal flywheel 02 without any contact. When the user rotates the metal flywheel 02, the attraction force is weak when the permanent magnet 03 is directly opposite the slot 021, and even weaker when it is directly opposite the slot 021. This interval design achieves a distinct tactile feedback, eliminating the need for electromagnetic components and effectively avoiding the performance and lifespan limitations caused by electronic components. Furthermore, by designing the flywheel as metal, the tactile feedback is achieved simply by adding the permanent magnet 03 to a standard flywheel structure, without the need for additional grating structures. The entire flywheel structure is simple, and the low cost of the permanent magnet 03 reduces production costs, effectively meeting the needs of modern production. By placing the permanent magnet 03 on the bracket 01 and extending it toward the metal flywheel 02, the permanent magnet 03 is made closer to the metal flywheel 02, resulting in more precise and agile magnetic interference with the metal flywheel 02, further ensuring the segmented feel of this flywheel structure.

[0036] Preferably, the metal flywheel 02 is made of silicon steel. Silicon steel has high magnetic permeability and low hysteresis characteristics, as well as good resistivity and conductivity, which can effectively reduce hysteresis loss and eddy current loss when magnetic flux passes through it, and improve the energy efficiency of the equipment.

[0037] Preferably, as shown in Figures 2 to 5, in order to ensure the feel of the flywheel structure, the width of the permanent magnet 03 is less than or equal to the length of the side of the spacer slot 021, so that the strength of the attraction force of the permanent magnet 03 on the spacer slot 021 is more distinct, and the problem of the permanent magnet 03 being magnetically attracted to the inner or outer ring of the metal flywheel 02, resulting in the inability to produce a tactile feedback, is prevented.

[0038] Preferably, as shown in Figures 2 to 5, in order to further ensure the feel of the flywheel structure, the height of the permanent magnet 03 is less than or equal to the height of the spacer slot 021, thereby effectively preventing the permanent magnet 03 from being magnetically attracted to both the spacer slot 021 and the metal flywheel 02 at the same time and continuously, thus preventing the problem of not being able to produce a tactile feel, and effectively ensuring the tactile feel of the flywheel structure.

[0039] As shown in Figures 2 to 5, the permanent magnet 03 is arranged in two sets: a first permanent magnet 031 located on the left side of one end of the bracket 01 and a second permanent magnet 032 located on the right side of one end of the bracket 01. This ensures that the magnetic attraction force on both sides of one end of the metal flywheel 02 is uniform, providing the user with a more stable and distinct tactile feedback, thereby improving the user experience.

[0040] Preferably, as shown in Figures 2 to 5, the permanent magnet 03 has two additional sets: a third permanent magnet 033 disposed on the left side of the other end of the bracket 01, and a fourth permanent magnet 034 disposed on the right side of the other end of the bracket 01. The four sets of permanent magnets are symmetrically disposed on the four corners of the bracket 01, so that the magnetic attraction force on the four corners of the metal flywheel 02 is uniform, providing the user with a more stable and more obvious tactile feedback, thereby improving the user's user experience.

[0041] The size of the interval slots 021 and the distance between them can be set according to the size of the permanent magnets 03, so as to ensure that the first permanent magnet 031, the second permanent magnet 032, the third permanent magnet 033, and the fourth permanent magnet 034 are simultaneously in the position directly opposite the interval slots 021 when the metal flywheel 02 rotates, or all four are in the position directly opposite the metal flywheel 02. This ensures that the metal flywheel 02 is subjected to the same attraction force, and prevents some permanent magnets 03 from being directly opposite the metal sheet and others from being directly opposite the interval slots 021, which would cause the attraction force of the metal flywheel 02 to be uneven and not produce a clear sense of segmentation. This effectively ensures the overall user experience of this flywheel structure.

[0042] As shown in Figures 2 to 7, the flywheel structure further includes a first limiting member 04 that is L-shaped and can be embedded in the bracket 01. A first mounting groove 041 for mounting the first permanent magnet 031 is formed in the middle of the first limiting member 04. By installing the first permanent magnet 031 into the first mounting groove 041 and then embedding the first limiting member 04 into the bracket 01, the first permanent magnet 031 is fixedly installed. To further secure the first permanent magnet 031, it can be further fixed using adhesive or other methods when installed in the first mounting groove 041.

[0043] As shown in Figures 2 to 7, the flywheel structure further includes a second limiting member 05 that is L-shaped and can be embedded in the bracket 01. A second mounting groove 051 for mounting the second permanent magnet 032 is formed in the middle of the second limiting member 05. By installing the second permanent magnet 032 into the second mounting groove 051 and then embedding the second limiting member 05 into the bracket 01, the fixed installation of the second permanent magnet 032 is completed. To further secure the second permanent magnet 032, it can be further fixed using adhesive or other methods when installed in the second mounting groove 051.

[0044] As shown in Figures 2 to 7, the flywheel structure further includes a third limiting member 06 that is L-shaped and can be embedded in the bracket 01. The third limiting member 06 has a third mounting groove 061 formed in its center for mounting the third permanent magnet 033. By installing the third permanent magnet 033 into the third mounting groove 061 and then embedding the third limiting member 06 into the bracket 01, the fixed installation of the third permanent magnet 033 is completed. To further secure the third permanent magnet 033, it can be further fixed in the third mounting groove 061 using adhesive or other methods.

[0045] As shown in Figures 2 to 7, the flywheel structure further includes a fourth limiting member 07, which is L-shaped and can be embedded in the bracket 01. The fourth limiting member 07 has a fourth mounting groove 071 formed in its center for mounting the fourth permanent magnet 034. By installing the fourth permanent magnet 034 into the fourth mounting groove 071 and then embedding the fourth limiting member 07 into the bracket 01, the fourth permanent magnet 034 is fixedly installed. To further secure the fourth permanent magnet 034, it can be further fixed using adhesive or other methods when installed in the fourth mounting groove 071.

[0046] The specific structural settings of the first limiting member 04, the second limiting member 05, the third limiting member 06, and the fourth limiting member 07 are shown in Figures 2 to 7. The first limiting member 04, the second limiting member 05, the third limiting member 06, and the fourth limiting member 07 extend toward the metal flywheel 02, so that the first permanent magnet 031, the second permanent magnet 032, the third permanent magnet 033, and the fourth permanent magnet 034, which are respectively disposed therein, are closer to the metal flywheel 02, but do not directly contact the metal flywheel 02. This makes the interference with the metal flywheel 02 more precise and agile, and further ensures the segmented feel of this flywheel structure.

[0047] As shown in Figures 2 to 7, the first limiting member 04, the second limiting member 05, the third limiting member 06, and the fourth limiting member 07 are specifically disposed on the bracket 01. The bracket 01 has an L-shaped first embedding groove 011 for the first limiting member 04 to be inserted, an L-shaped second embedding groove 012 for the second limiting member 05 to be inserted, an L-shaped third embedding groove 013 for the third limiting member 06 to be inserted, and an L-shaped fourth embedding groove 014 for the fourth limiting member 07 to be inserted. The first limiting member 04 is inserted into the first embedding groove 011, the second limiting member 05 is inserted into the second embedding groove 012, the third limiting member 06 is inserted into the third embedding groove 013, and the fourth limiting member 07 is inserted into the fourth embedding groove 014, thereby completing the installation of the first limiting member 04, the second limiting member 05, the third limiting member 06, and the fourth limiting member 07, ensuring the normal operation of this flywheel structure. The L-shaped structure allows the first limiting member 04, the second limiting member 05, the third limiting member 06, and the fourth limiting member 07 to be clamped onto the bracket 01 by one end of their short sides, thus being limited by the bracket 01 and preventing the first limiting member 04, the second limiting member 05, the third limiting member 06, and the fourth limiting member 07 from being displaced by the permanent magnet 03, ensuring the normal operation of this flywheel structure.

[0048] To further prevent the first limiting member 04 from shifting, as shown in Figures 2 to 7, the flywheel structure also includes a first baffle 08 that covers the first embedded groove 011 and blocks and limits the rear ends of the first permanent magnet 031 and the first limiting member 04. The first baffle 08 is installed on the bracket 01 to block and limit the rear ends of the first permanent magnet 031 and the first limiting member 04, preventing the first limiting member 04 from falling off and shifting at the rear end, and ensuring the normal use of the first permanent magnet 031.

[0049] To further prevent the second limiting member 05 from shifting, as shown in Figures 2 to 7, the flywheel structure also includes a second baffle 09 that covers the second embedding groove 012 and blocks and limits the rear ends of the second permanent magnet 032 and the second limiting member 05. The second baffle 09 is installed on the bracket 01 to block and limit the rear ends of the second permanent magnet 032 and the second limiting member 05, preventing the second limiting member 05 from falling off and shifting at the rear end, and ensuring the normal use of the second permanent magnet 032.

[0050] To further prevent the third limiting member 06 from shifting, as shown in Figures 2 to 7, the flywheel structure also includes a third baffle 10 that covers the third embedded groove 013 and blocks and limits the rear ends of the third permanent magnet 033 and the third limiting member 06. The third baffle 10 is installed on the bracket 01 to block and limit the rear ends of the third permanent magnet 033 and the third limiting member 06, preventing the third limiting member 06 from falling off and shifting at the rear end, and ensuring the normal use of the third permanent magnet 033.

[0051] To further prevent the fourth limiting member 07 from shifting, as shown in Figures 2 to 7, the flywheel structure also includes a fourth baffle 11 that covers the fourth embedded groove 014 and blocks and limits the rear ends of the fourth permanent magnet 034 and the fourth limiting member 07. The fourth baffle 11 is installed on the bracket 01 to block and limit the rear ends of the fourth permanent magnet 034 and the fourth limiting member 07, preventing the fourth limiting member 07 from falling off and shifting at the rear end, and ensuring the normal use of the fourth permanent magnet 034.

[0052] As shown in Figures 2 to 7, a first fixing block 081 is formed below the first baffle 08 and can be embedded in the bracket 01. A first fixing groove 015 is formed on the lower side of one end of the bracket 01 for the first fixing block 081 to be embedded. By embedding the first fixing block 081 into the first fixing groove 015, the entire first baffle 08 is fixed, preventing the first baffle 08 from shifting and achieving the purpose of stably blocking and limiting the first limiting member 04.

[0053] As shown in Figures 2 to 7, a second fixing block 091 is formed below the second baffle 09 and can be embedded in the bracket 01. A second fixing groove 016 is formed on the lower side of one end of the bracket 01 for the second fixing block 091 to be embedded. By embedding the second fixing block 091 into the second fixing groove 016, the entire second baffle 09 is fixed, preventing the second baffle 09 from shifting and achieving the purpose of stably blocking and limiting the second limiting member 05.

[0054] As shown in Figures 2 to 7, a third fixing block 101 is formed below the third baffle 10 and can be embedded in the bracket 01. A third fixing groove 017 is formed on the lower side of the other end of the bracket 01 for the third fixing block 101 to be embedded. By embedding the third fixing block 101 into the third fixing groove 017, the entire third baffle 10 is fixed, preventing the third baffle 10 from shifting and achieving the purpose of stably blocking and limiting the third limiting member 06.

[0055] As shown in Figures 2 to 7, the fourth baffle 11 is fixed by a fourth fixing block 111 that can be embedded in the bracket 01. The lower part of the other side of the bracket 01 is formed with a fourth fixing groove 018 for the fourth fixing block 111 to be embedded. By embedding the fourth fixing block 111 into the fourth fixing groove 018, the entire fourth baffle 11 is fixed, preventing the fourth baffle 11 from shifting and achieving the purpose of stably blocking and limiting the fourth limiting member 07.

[0056] Preferably, as shown in Figures 2 to 7, in order to further fix the first baffle 08, a first guide limiting block 019 is formed on the upper part of one side of the bracket 01, which abuts against the upper surface of the first baffle 08. After the first baffle 08 is installed, the first guide limiting block 019 abuts against the upper surface of the first baffle 08, thereby cooperating with the first fixing groove 015 to fix the first baffle 08 in the upper and lower positions, further fixing the first baffle 08 and preventing the first baffle 08 from shifting.

[0057] Preferably, as shown in Figures 2 to 7, in order to further fix the second baffle 09, a second guide limiting block 0110 is formed on the upper part of one side of the bracket 01, which abuts against the upper surface of the second baffle 09.

[0058] Preferably, as shown in Figures 2 to 7, in order to further fix the third baffle 10, a third guide limiting block 0111 is formed on the upper part of one side of the bracket 01, which abuts against the upper surface of the third baffle 10. After the third baffle 10 is installed, the third guide limiting block 0111 abuts against the upper surface of the third baffle 10, thereby cooperating with the third fixing groove 017 to fix the third baffle 10 in the upper and lower positions, further fixing the third baffle 10 and preventing the third baffle 10 from shifting.

[0059] Preferably, as shown in Figures 2 to 7, in order to further fix the fourth baffle 11, a fourth guide limiting block 0112 is formed on the upper part of one side of the bracket 01, which abuts against the upper surface of the fourth baffle 11. After the fourth baffle 11 is installed, the fourth guide limiting block 0112 abuts against the upper surface of the fourth baffle 11, thereby cooperating with the fourth fixing groove 018 to fix the fourth baffle 11 in the upper and lower positions, further fixing the fourth baffle 11 and preventing the fourth baffle 11 from shifting.

[0060] Preferably, as shown in Figures 2 to 7, in order to make the first baffle 08 easier to install, a first inclined guide surface 0191 is formed on the upper end surface of the first guide limiting block 019, which extends outward and downward from the metal flywheel 02. When the first baffle 08 is installed, the lower end of the first baffle 08 first contacts the first inclined guide surface 0191 and slides downward under the inclined guidance of the first inclined guide surface 0191, thereby better installing it in the first fixing groove 015 and improving the assembly efficiency and assembly accuracy of the flywheel structure.

[0061] Preferably, as shown in Figures 2 to 7, in order to make the second baffle 09 easier to install, a second inclined guide surface 01101 is formed on the upper end surface of the second guide limiting block 0110, which extends outward and downward from the metal flywheel 02. When the second baffle 09 is installed, the lower end of the second baffle 09 first contacts the second inclined guide surface 01101 and slides downward under the inclined guiding action of the second inclined guide surface 01101, thereby better installing it in the second fixing groove 016 and improving the assembly efficiency and assembly accuracy of this flywheel structure.

[0062] Preferably, as shown in Figures 2 to 7, in order to make the third baffle 10 easier to install, a third inclined guide surface 01111 is formed on the upper end surface of the third guide limiting block 0111, which extends outward and downward from the metal flywheel 02. When the third baffle 10 is installed, the lower end of the third baffle 10 first contacts the third inclined guide surface 01111, and slides downward under the inclined guidance of the third inclined guide surface 01111, thereby better installing it in the third fixing groove 017 and improving the assembly efficiency and assembly accuracy of this flywheel structure.

[0063] Preferably, as shown in Figures 2 to 7, in order to make the fourth baffle 11 easier to install, a fourth inclined guide surface 01121 is formed on the upper end surface of the fourth guide limiting block 0112, which extends inclinedly outward and downward from the metal flywheel 02. When the fourth baffle 11 is installed, the lower end of the fourth baffle 11 first contacts the fourth inclined guide surface 01121, and slides downward under the inclined guiding action of the fourth inclined guide surface 01121, thereby better installing it in the fourth fixing groove 018 and improving the assembly efficiency and assembly accuracy of this flywheel structure.

[0064] Other operating structures and methods of this flywheel structure can be set according to actual conditions. For example, the metal flywheel 02 is provided with a magnetic ring and a Hall element facing the magnetic ring. When the metal flywheel 02 rotates, the magnetic ring is driven to rotate synchronously. The Hall element senses the magnetic ring and outputs a signal. These are all existing technologies in the field, so they will not be described in detail in this embodiment.

[0065] It should be noted that the flywheel structure with segmented tactile feedback disclosed in this utility model is an improvement on a specific structure, but the specific control method is not an innovation of this utility model. The permanent magnets, magnetic rings, Hall elements, and other components involved in this utility model can be general standard parts or components known to those skilled in the art. Their structures, principles, and control methods are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0066] 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.
