Abstract
Description
Technical Field
[0001] This utility model relates to the field of input technology, and in particular to a flywheel module with a segmented feel. 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] Traditional rollers experience internal wear over time, so a new type of roller utilizes the properties of electromagnets. The inner ring of the roller is lined with a ferromagnetic material, and inside 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 "segment." When switched to undamped mode, the current in the electromagnet reverses direction, and the electromagnet and permanent magnet have opposite polarities. In this mode, the magnetic field lines are confined to the roller core, exerting no magnetic force on the outer ferromagnetic ring, allowing it 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 module with a distinct sense of segmentation. This module eliminates the need for electromagnetic components and utilizes only the magnetic attraction of permanent magnets to the inner and outer magnetic absorbing plates to create a clear sense of segmentation during the free rotation of the flywheel. This effectively avoids the problem of limited product performance and lifespan caused by electronic components. Furthermore, this flywheel module has a simple structure and low production cost, 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 segmented flywheel module includes a flywheel bracket and a flywheel body rotatably mounted on the flywheel bracket. It also includes a magnetic adsorption assembly disposed within the flywheel body. The flywheel bracket has at least one permanent magnet directly opposite the flywheel body. The flywheel body includes an inner ring body mounted on the flywheel bracket, an outer ring body surrounding the inner ring body, and a magnet insertion groove formed between the inner and outer ring bodies for the permanent magnet to be inserted. The magnetic adsorption assembly includes several inner magnetic absorbing plates mounted on the inner ring body and several outer magnetic absorbing plates mounted on the outer ring body with spacing matching that of the inner magnetic absorbing plates. The permanent magnet does not contact either the inner or outer magnetic absorbing plates, and the permanent magnet performs magnetic interference with both the inner and outer magnetic absorbing plates.
[0009] As a further improvement of this utility model, the permanent magnet is trapezoidal in shape, with the length of its upper base near the inner magnetic absorbing sheet being longer than the width of the inner magnetic absorbing sheet, and the length of its lower base near the outer magnetic absorbing sheet being longer than the outer magnetic absorbing sheet.
[0010] As a further improvement of this utility model, the permanent magnet is trapezoidal in shape, with the length of its upper base near the inner magnetic absorbing sheet being less than the spacing width between the two sets of inner magnetic absorbing sheets, and the length of its lower base near the outer magnetic absorbing sheet being less than the spacing width between the two sets of outer magnetic absorbing sheets.
[0011] 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 magnet insertion ring groove. They are a first permanent magnet arranged in one side of the magnet insertion ring groove and a second permanent magnet arranged in the other side of the magnet insertion ring groove.
[0012] As a further improvement of this utility model, it also includes a first limiting member that is T-shaped and embedded in one side of the flywheel bracket and extends to the magnet insertion ring groove, and a second limiting member that is T-shaped and embedded in the other side of the flywheel bracket and extends to the magnet insertion ring groove. The first limiting member has a first mounting groove formed in the middle for mounting the first permanent magnet, and the second limiting member has a second mounting groove formed in the middle for mounting the second permanent magnet.
[0013] As a further improvement of this utility model, a first embedding groove for the first limiting member to be inserted and a second embedding groove symmetrical to the first embedding groove for the second limiting member to be inserted are formed on the side of the flywheel bracket.
[0014] As a further improvement of this utility model, it also includes a first baffle plate embedded in the outermost part of the first embedding groove and blocking and limiting the rear ends of the first permanent magnet and the first limiting member, and a second baffle plate embedded in the outermost part of the second embedding groove and blocking and limiting the rear ends of the second permanent magnet and the second limiting member.
[0015] As a further improvement of this utility model, the width of the T-shaped head of the first limiting member is greater than the width of the first embedding groove, and the width of the T-shaped head of the second limiting member is greater than the width of the second embedding groove.
[0016] As a further improvement of this utility model, the magnetic adsorption assembly further includes a plurality of inner ring metal sheets disposed within the inner ring body and stacked on top of each other, and a plurality of outer ring metal sheets disposed within the outer ring body and stacked on top of each other. The inner magnetic adsorption sheet is formed on the outer side of the inner ring metal sheet and extends toward the outer ring metal sheet, and the outer magnetic adsorption sheet is formed on the inner side of the outer ring metal sheet and extends toward the inner ring metal sheet.
[0017] As a further improvement of this utility model, the magnetic adsorption assembly further includes a connecting ring disposed in the flywheel body and connecting the inner magnetic adsorption piece and the outer magnetic adsorption piece.
[0018] The beneficial effects of this utility model are as follows:
[0019] This flywheel module is configured to include a flywheel bracket and a flywheel body rotatably mounted on the flywheel bracket, and a magnetic adsorption component disposed within the flywheel body. The flywheel bracket is provided with at least one permanent magnet directly opposite the flywheel body. The flywheel body includes an inner ring body disposed on the flywheel bracket, an outer ring body disposed around the inner ring body, and a magnet insertion groove formed between the inner and outer ring bodies for the permanent magnet to be inserted. The magnetic adsorption component includes several inner magnetic absorbing plates disposed on the inner ring body and several outer magnetic absorbing plates disposed on the outer ring body with a spacing matching that of the inner magnetic absorbing plates. The permanent magnet does not contact the inner or outer magnetic absorbing plates, and the permanent magnet performs magnetic interference with the inner and outer magnetic absorbing plates.
[0020] The permanent magnet magnetically attracts the inner and outer magnetic plates without any gaps. When the flywheel rotates, the inner and outer magnetic plates are driven to rotate synchronously. When the permanent magnet is positioned between the inner and outer magnetic plates, the attraction force on the inner and outer magnetic plates is strong. When the permanent magnet is positioned between the two sets of inner magnetic plates and the two sets of outer magnetic plates, the attraction force on the inner and outer magnetic plates is weak. The spacing creates a distinct sense of segmentation. Furthermore, it eliminates the need for electromagnetic components, effectively avoiding the product performance and lifespan limitations caused by electronic components. This flywheel module has a simple structure and uses inexpensive permanent magnets, reducing production costs and effectively meeting the needs of modern production. The permanent magnet is placed in the annular groove and does not contact the inner or outer magnetic absorbing plate. This effectively prevents the flywheel body from being unable to rotate after the permanent magnet is magnetically attracted to the inner or outer magnetic absorbing plate. Furthermore, the permanent magnet is closer to the inner and outer magnetic absorbing plates, making the magnetic attraction of the inner and outer magnetic absorbing plates more precise and agile, further ensuring the tactile feedback of this flywheel module.

[0034] 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.
[0035] Example 1
[0036] Reference Figures 1 to 4 This utility model embodiment provides a flywheel module with segmented design, including a flywheel bracket 1 and a flywheel body 2 rotatably mounted on the flywheel bracket 1, and a magnetic adsorption component 3 disposed within the flywheel body 2. The flywheel bracket 1 is provided with at least one permanent magnet 4 directly opposite the flywheel body 2. The flywheel body 2 includes an inner ring 21 disposed on the flywheel bracket 1, an outer ring 22 disposed around the inner ring 21, and a component formed within the flywheel bracket 1. A magnet insertion groove 23 is provided between the inner ring body 21 and the outer ring body 22 for the permanent magnet 4 to be inserted. The magnetic adsorption assembly 3 includes several inner magnetic absorbing plates 31 disposed on the inner ring body 21 and several outer magnetic absorbing plates 32 disposed on the outer ring body 22 with a spacing matching that of the inner magnetic absorbing plates 31. The permanent magnet 4 does not contact the inner magnetic absorbing plates 31 or the outer magnetic absorbing plates 32. The permanent magnet 4 performs magnetic interference on the inner magnetic absorbing plates 31 and the outer magnetic absorbing plates 32.
[0037] The permanent magnet 4 magnetically attracts the inner magnetic absorbing plate 31 and the outer magnetic absorbing plate 32 in a distance. When the flywheel body 2 rotates, the inner magnetic absorbing plate 31 and the outer magnetic absorbing plate 32 are driven to rotate synchronously by the flywheel body 2. When the permanent magnet 4 is located between the inner magnetic absorbing plate 31 and the outer magnetic absorbing plate 32, the attraction force on the inner magnetic absorbing plate 31 and the outer magnetic absorbing plate 32 is strong. When the permanent magnet is located between the two sets of inner magnetic absorbing plates 31 and the two sets of outer magnetic absorbing plates 32, the attraction force on the inner magnetic absorbing plate 31 and the outer magnetic absorbing plate 32 is weak. The interval setting achieves a clear sense of segmentation, and there is no need to use electromagnetic components, which effectively avoids the problem of product performance and lifespan limitation caused by electronic components. In addition, the structure of this flywheel module is simple, the price of the permanent magnet 4 is low, reducing production costs and effectively meeting the development needs of modern production. The permanent magnet 4 is placed within the magnet insertion groove 23 and does not contact either the inner magnetic absorbing plate 31 or the outer magnetic absorbing plate 32. This effectively prevents the flywheel body 2 from being unable to rotate after the permanent magnet 4 is magnetically attracted to either the inner or outer magnetic absorbing plate 31 or the outer magnetic absorbing plate 32. Furthermore, the permanent magnet 4 is closer to the inner and outer magnetic absorbing plates 31 and 32, resulting in more precise and agile magnetic attraction to them, further ensuring the tactile feedback of this flywheel module. By setting the outer magnetic absorbing plate 32 to match the spacing of the inner magnetic absorbing plate 31, when the flywheel body 2 rotates, the outer magnetic absorbing plate 32 and the inner magnetic absorbing plate 31 are either simultaneously facing the permanent magnet 4 or not simultaneously facing the permanent magnet 4. This effectively prevents the problem of insufficient attraction strength when the permanent magnet 4 is only magnetically attracted to the outer magnetic absorbing plate 32 or the inner magnetic absorbing plate 31, thus failing to produce a tactile feedback.
[0038] Preferably, both the inner magnetic absorbing sheet 31 and the outer magnetic absorbing sheet 32 are silicon steel sheets, which have 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 them, and improve the energy efficiency of the equipment.
[0039] Regarding the specific structural configuration of the permanent magnet 4, as follows: Figures 2 to 4 As shown, the permanent magnet 4 is trapezoidal in shape. The length of its upper base near the inner magnetic absorbing piece 31 is longer than the width of the inner magnetic absorbing piece 31, and the length of its lower base near the outer magnetic absorbing piece 32 is longer than the outer magnetic absorbing piece 32. This makes it easier for the permanent magnet 4 to magnetically attract the inner magnetic absorbing piece 31 and the outer magnetic absorbing piece 32, thereby producing a sudden sensation.
[0040] Preferred, such as Figures 2 to 4As shown, the permanent magnet 4 is trapezoidal in shape. The length of its upper base near the inner magnetic absorbing plate 31 is less than the spacing between the two sets of inner magnetic absorbing plates 31, and the length of its lower base near the outer magnetic absorbing plate 32 is less than the spacing between the two sets of outer magnetic absorbing plates 32. This prevents the permanent magnet 4 from being simultaneously attracted to the two sets of inner magnetic absorbing plates 31 or the two sets of outer magnetic absorbing plates 32, thus avoiding the problem of not being able to produce a tactile feedback. This effectively ensures the tactile feedback of this flywheel module.
[0041] Preferred, such as Figures 2 to 4 As shown, there are two sets of permanent magnets 4, which are symmetrically arranged in the magnet insertion ring groove 23. They are a first permanent magnet 41 arranged in one side of the magnet insertion ring groove 23 and a second permanent magnet 42 arranged in the other side of the magnet insertion ring groove 23. This makes the magnetic attraction force on both sides of the inner magnetic absorbing piece 31 and the outer magnetic absorbing piece 32 uniform, providing the user with a more stable and obvious segmented feel, thereby improving the user's user experience.
[0042] Regarding the specific fixing method of the permanent magnet 4, such as Figures 1 to 3 As shown, this flywheel structure also includes a first limiting member 5, which is T-shaped and embedded in one side of the flywheel bracket 1, extending to the magnet insertion annular groove 23; and a second limiting member 6, which is T-shaped and embedded in the other side of the flywheel bracket 1, extending to the magnet insertion annular groove 23. The first limiting member 5 has a first mounting groove 51 formed in its middle for mounting the first permanent magnet 414, and the second limiting member 6 has a second mounting groove 61 formed in its middle for mounting the second permanent magnet 424. By mounting the first permanent magnet 41 in the first mounting groove 51 and then embedding the first limiting member 5 into the flywheel bracket 1, the first permanent magnet 41 is fixedly installed. By mounting the second permanent magnet 42 in the second mounting groove 61 and then embedding the second limiting member 6 into the flywheel bracket 1, the second permanent magnet 42 is fixedly installed. By setting both the first limiting member 5 and the second limiting member 6 to extend into the magnet insertion groove 23, the first permanent magnet 41 and the second permanent magnet 42, which are respectively set in the first limiting member 5, are closer to the inner magnetic absorbing piece 31 and the outer magnetic absorbing piece 32, but do not directly contact each other. This makes the interference of the inner magnetic absorbing piece 31 and the outer magnetic absorbing piece 32 more precise and agile, further ensuring the segmentation of this flywheel module.
[0043] Preferably, as shown in 3, openings are provided on both sides of the first limiting member 5 and the second limiting member 6, so that the first permanent magnet 41 disposed in the first limiting member 5 and the second permanent magnet 42 disposed in the second limiting member 6 can more easily magnetically attract the inner magnetic absorbing piece 31 and the outer magnetic absorbing piece 32, thereby forming a distinct segmented feel.
[0044] Regarding the specific method of installing the first limiting member 5 and the second limiting member 6 on the flywheel bracket 1, as follows: Figure 3 As shown, the flywheel bracket 1 has a first embedding groove 11 for the first limiting member 5 to be inserted into, and a second embedding groove 12 symmetrical to the first embedding groove 11 for the second limiting member 6 to be inserted into. The first limiting member 5 is inserted into the first embedding groove 11, and the second limiting member 6 is inserted into the second embedding groove 12, thereby completing the fixed installation of the first limiting member 5 and the second limiting member 6 and ensuring the normal operation of the flywheel module.
[0045] To prevent the first limiting member 5 from falling out of the first embedding groove 11 and the second limiting member 6 from falling out of the second embedding groove 12, such as Figure 2 and Figure 3 As shown, the width of the T-shaped head of the first limiting member 5 is greater than the width of the first embedding groove 11, so that the T-shaped head of the first limiting member 5 is locked in the first embedding groove 11. The T-shaped extension extends towards the magnet insertion annular groove 23, thereby ensuring that the first permanent magnet 414 inside can accurately perform magnetic interference on the inner magnetic absorbing piece 31 and the outer magnetic absorbing piece 32 while being limited. The width of the T-shaped head of the second limiting member 6 is greater than the width of the second embedding groove 12, so that the T-shaped head of the second limiting member 6 is locked in the second embedding groove 12. The T-shaped extension extends towards the magnet insertion annular groove 23, thereby ensuring that the second permanent magnet 424 inside can accurately perform magnetic interference on the inner magnetic absorbing piece 31 and the outer magnetic absorbing piece 32 while being limited.
[0046] To further prevent the first limiting member 5 and the second limiting member 6 from shifting, such as Figures 1 to 3 As shown, the device also includes a first baffle 7 embedded in the outermost part of the first embedding groove 11, which abuts and limits the rear ends of the first permanent magnet 41 and the first limiting member 5; and a second baffle 8 embedded in the outermost part of the second embedding groove 12, which abuts and limits the rear ends of the second permanent magnet 42 and the second limiting member 6. By placing the first baffle 7 into the outermost part of the first embedding groove 11, the rear ends of the first permanent magnet 41 and the first limiting member 5 are abutted and limited, preventing the first limiting member 5 from falling off and shifting at the rear end, thus ensuring the normal use of the first permanent magnet 41. By placing the second baffle 8 into the outermost part of the second embedding groove 12, the rear ends of the second permanent magnet 42 and the second limiting member 6 are abutted and limited, preventing the second limiting member 6 from falling off and shifting at the rear end, thus ensuring the normal use of the second permanent magnet 42.
[0047] Preferred, such as Figure 1As shown, an outer ring platform is formed on the outer ring body 22, extending toward the inner ring body 21. The outer magnetic absorbing piece 32 is embedded in the outer ring platform, thereby limiting the outer magnetic absorbing piece 32 and effectively preventing the outer magnetic absorbing piece 32 from shifting during operation, thus ensuring the segmentation of this flywheel module.
[0048] Preferred, such as Figure 1 As shown, an inner ring platform is formed on the inner ring body 21, extending toward the outer ring body 22. The inner magnetic absorbing piece 31 is embedded in the inner ring platform, thereby limiting the inner magnetic absorbing piece 31 and effectively preventing the inner magnetic absorbing piece 31 from shifting during operation, thus ensuring the segmentation of this flywheel module.
[0049] For other structural configurations of the magnetic adsorption component 3, such as Figure 3 and Figure 4 As shown, the magnetic adsorption component 3 also includes several inner ring metal sheets 33 disposed within the inner ring body 21 and stacked together, and several outer ring metal sheets 34 disposed within the outer ring body 22 and stacked together. The inner magnetic adsorption sheet 31 is formed on the outer side of the inner ring metal sheet 33 and extends toward the outer ring metal sheet 34, and the outer magnetic adsorption sheet 32 is formed on the inner side of the outer ring metal sheet 34 and extends toward the inner ring metal sheet 33. Thus, it can get closer to the permanent magnet 4 without contacting it, and the stacked structure makes the magnetism stronger, which is more conducive to the permanent magnet 4 to perform magnetic interference on the inner magnetic adsorption sheet 31 and the outer magnetic adsorption sheet 32. This makes the adsorption force of the flywheel module distinct when it rotates, and improves the segmentation of the flywheel module.
[0050] Other operating structures and methods of this flywheel component can be set according to actual conditions. For example, the flywheel body 2 is provided with a magnetic ring and a Hall element opposite the magnetic ring. When the flywheel body 2 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.
[0051] Example 2
[0052] In the first embodiment, the structure of the flywheel module was described. This embodiment mainly focuses on the differences from other embodiments; identical structures will not be repeated in this embodiment.
[0053] like Figures 5 to 8The main difference between Embodiment 2 and Embodiment 1 is that in this embodiment, the magnetic adsorption component 3 further includes a connecting ring 35 disposed within the flywheel body 2, connecting the inner magnetic adsorption piece 31 and the outer magnetic adsorption piece 32. The connecting ring 35 is embedded within the flywheel body 2, effectively limiting its position, thereby limiting the inner magnetic adsorption piece 31 and the outer magnetic adsorption piece 32 connected to it. This effectively prevents displacement of the inner and outer magnetic adsorption pieces 31 and 32, ensuring the normal operation of the flywheel module. Using a single connecting ring 35, compared to the structure of multiple stacked metal pieces in Embodiment 1, its structure is simpler, cheaper, and effectively reduces production costs while improving production efficiency.
[0054] It should be noted that the segmented flywheel module disclosed in this utility model is an improvement on the 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 known to those skilled in the art through technical manuals or conventional experimental methods.
[0055] 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.
