Description

TECHNICAL FIELD

[0001] The present invention relates to a fitness equipment, and in particular, to a flywheel assembly, a magnetic control device in the flywheel assembly and a fitness equipment. BACKGROUND

[0002] A flywheel assembly is a key part of a fitness equipment (e.g. a spin bike, an elliptical machine), and a conventional flywheel assembly includes a magnetic control device and a flywheel surrounding the magnetic control device, wherein the magnetic control device provides a magnetically permeable body and a magnetic element disposed on the magnetically permeable body, and the flywheel provides a conductor, and when the flywheel is driven to rotate relative to the magnetic control device, the magnetically permeable body disposed on the flywheel cuts the magnetic flux of the magnetic control device to obtain a load, so as to allow a user to achieve the purpose of fitness by using the fitness equipment. Although the magnetic element disposed on the magnetically permeable body can enhance the magnetic field strength of the magnetic control device, for the conventional flywheel assembly, the magnetically permeable body and the magnetic element of the magnetic control device are both located inside the conductor of the flywheel, and the magnetic field of the magnetic control device is mainly concentrated between the magnetically permeable body and the magnetic element, which means that the conductor of the flywheel is located at the edge of the magnetic field of the magnetic control device. That is, when the flywheel drives the conductor to rotate relative to the magnetic control device, the conductor can only cut the magnetic flux of the magnetic control device at the edge of the magnetic field of the magnetic control device to obtain a load, which results in that the flywheel assembly has a low utilization rate of the magnetic field of the magnetic control device and requires a high magnetic field strength of the magnetic control device.

[0077] The following description is presented to enable any person skilled in the art to practice the present application as claimed. The preferred embodiments disclosed herein are only examples of the present application and alternative embodiments, modifications, improvements, equivalents, and the like can be made thereto without departing from the spirit and scope of the present application as set forth in the following claims. The present application is defined in the following claims.

[0078] ​Those skilled in the art will understand that the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, used in the disclosure of the present application indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore the above terms cannot be understood as a limitation on the present application.

[0079] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0080] The Figure 1 A fitness equipment according to a first preferred embodiment of the present application is shown, which is an elliptical machine, wherein the fitness equipment comprises a flywheel assembly 100, an equipment frame 200, and an operating part 300 operably arranged at the equipment frame 200, the flywheel assembly 100 comprises an inner magnetic control device 10 and a flywheel 20, the inner magnetic control device 10 is fixedly arranged at the equipment frame 200, the flywheel 20 is arranged around the inner magnetic control device 10 and is drivably connected to the operating part 300, and a user uses the fitness equipment for fitness by operating the operating part 300. For example, in the drawings Figure 1 In this specific example of the fitness equipment shown, the operating part 300 can be pedal type to allow a user to use the fitness equipment for fitness by pedaling the operating part 300.

[0081] It is worth mentioning that the Figure 1 The fitness equipment shown in the drawings, which is implemented as an elliptical machine, is only exemplary and does not limit the specific type of the fitness equipment of the present application. For example, in other examples of the fitness equipment of the present application, the fitness equipment can also be a spinning bike, a rowing machine, etc.

[0082] The Figures 2A to 6 A specific example of the flywheel assembly 100 is shown, wherein the flywheel assembly 100 comprises the inner magnetic control device 10 and the flywheel 20 arranged around the inner magnetic control device 10, the flywheel 20 is driven to rotate relative to the inner magnetic control device 10, so that the flywheel 20 obtains a load to help a user use the fitness equipment for fitness.

[0083] In particular, the flywheel 20 comprises a flywheel body 21 and at least one magnetic element 22, wherein the flywheel body 21 comprises a flywheel disc 211 and a flywheel rim 212 extending from the edge of the flywheel disc 211 to the side of the flywheel disc 211 to form a flywheel space 213 between the flywheel disc 211 and the flywheel rim 212, and wherein the magnetic element 22 is arranged on the flywheel rim 212 and located in the flywheel space 213 of the flywheel body 21.

[0084] Preferably, the flywheel rim 212 of the flywheel body 21 integrally extends from the edge of the flywheel disc 211 to the side of the flywheel disc 211. For example, in some embodiments, the flywheel disc 211 and the flywheel rim 212 of the flywheel body 21 are casted pieces which can be integrally formed by a casting process from a metal material, so that the flywheel body 21 has a heavy mass as a counterweight part of the flywheel 20.

[0085] In some embodiments, the number of the magnetic element 22 can be one, which is a complete ring. In other embodiments, the number of the magnetic element 22 can be two, and the two magnetic elements 22 are respectively bent to extend, wherein after the two magnetic elements 22 are arranged on the flywheel rim 212 of the flywheel body 21, the two magnetic elements 22 can form a complete magnetic ring. In yet other embodiments, the number of the magnetic element 22 can be more than three, and these magnetic elements 22 are respectively bent to extend or are cuboids, wherein after these magnetic elements 22 are arranged side by side on the flywheel rim 212 of the flywheel body 21, these magnetic elements 22 can form a complete magnetic ring.

[0086] It is worth mentioning that the way of arranging the magnetic element 22 on the flywheel rim 212 of the flywheel body 21 is not limited in the present application, as long as the magnetic element 22 can be reliably fixed on the flywheel rim 212 of the flywheel body 21 to allow the magnetic element 22 to rotate synchronously with the flywheel body 21. For example, in some embodiments, the magnetic element 22 can be integrally pressed on the flywheel rim 212 of the flywheel body 21, so as to facilitate simplifying the assembly process of the flywheel 20 and improving the assembly effect of the flywheel 20.

[0087] And, on one hand, even if no glue is provided between the magnetic element 22 and the wheel ring 212 of the flywheel body 21, as long as the sizes of the magnetic element 22 and the wheel ring 212 of the flywheel body 21 are properly matched, for example, the outer diameter size of the magnetic element 22 is consistent with the inner diameter size of the wheel ring 212 of the flywheel body 21, when the flywheel 20 is driven to rotate relative to the inner magnetic control device 20, under the action of centrifugal force, the magnetic element 22 can be tightly attached to the wheel ring 212 of the flywheel body 21 to avoid the magnetic element 22 from falling off the wheel ring 212 of the flywheel body 21, and the faster the rotation speed of the flywheel 20, the more tightly the magnetic element 22 can be attached to the wheel ring 212 of the flywheel body 21, which is conducive to ensuring the reliability of the flywheel assembly 100. On the other hand, there is no risk of reversing the N and S poles of the magnetic element 22 during assembly of the flywheel 20, which is crucial to ensuring the overall magnetic field strength of the magnetic element 22.

[0088] After the magnetic element 22 is provided on the wheel ring 212 of the flywheel body 21, the weight of the flywheel 20 can be increased. In other words, the magnetic element 22 can be used to provide a magnetic field and also to provide a counterweight.

[0089] In addition, by providing the magnetic element 22 on the wheel ring 212 of the flywheel body 21, the flywheel assembly 100 can quickly dissipate heat from the magnetic element 22 when the flywheel 20 is driven to rotate relative to the inner magnetic control device 10, thereby reducing the temperature of the magnetic element 22 itself and the surrounding environment, and avoiding the influence of heat on the magnetic field strength of the magnetic element 22 to prolong its service life.

[0090] Now turning to the drawings Figures 3A to 5BThe inner magnetic control device 10 includes a housing 11, at least one magnetic conductor 12 and at least one conductor 13. The magnetic conductor 12 is movably arranged in the housing 11, and the conductor 13 is arranged in the housing 11 and located outside the magnetic conductor 12. The inner magnetic control device 10 is arranged in the flywheel space 213 of the flywheel body 21, so that the conductor 13 is kept between the magnetic conductor 12 and the magnetic element 22. When the flywheel 20 is driven to rotate relative to the inner magnetic control device 10, the conductor 13 cuts the magnetic lines of the magnetic field formed between the magnetic element 22 and the magnetic conductor 12 to allow the flywheel 20 to obtain load, so that the user can achieve the purpose of fitness through the fitness equipment. By changing the position of the magnetic conductor 12, the strength of the magnetic field formed between the magnetic element 22 and the magnetic conductor 12 is changed to adjust the load that the flywheel 20 can obtain, thereby helping the user to achieve different fitness effects using the fitness equipment.

[0091] In the fitness equipment of the present application, by arranging the magnetic element 22 on the flywheel body 21 and arranging the magnetic conductor 12 and the conductor 13 in the housing 11 respectively and keeping the conductor 13 between the magnetic element 22 and the magnetic conductor 12, first, the flywheel body 21 and the magnetic element 22 can jointly serve as the counterweight part of the flywheel 20 to reduce the cost of the flywheel assembly 100, second, when the flywheel 20 is driven to rotate relative to the inner magnetic control device 10, the conductor 13 cuts the magnetic lines in the middle of the magnetic field formed between the magnetic conductor 12 and the magnetic element 22 to make the flywheel 20 obtain load, thereby efficiently utilizing the magnetic field and reducing the requirement for the strength of the magnetic field, third, when the flywheel 20 is driven to rotate relative to the inner magnetic control device 10, the magnetic element 22 can be closely attached to the rim 212 of the flywheel body 21 under the action of centrifugal force to avoid the magnetic element 22 from falling off, fourth, after the heat generated by the conductor 13 is radiated to the magnetic element 22 itself and the surrounding environment of the magnetic element 22, the flywheel body 21 can quickly dissipate heat to reduce the temperature of the magnetic element 22 itself and the surrounding environment, and fifth, the conductor 13 and the magnetic element 22 are always kept in place to ensure that the flywheel assembly 100 can provide good damping effect.

[0092] Continue to refer to the drawings Figure 2A , Figure 3A , Figure 3B , Figure 5A and Figure 5BThe flywheel assembly 100 further comprises a mounting shaft 30 and a flange 40 fixedly mounted on the mounting shaft 30. The housing 11 of the inner magnetic control device 10 has a housing hole 1101 penetrating through opposite sides of the housing 11. The flywheel body 21 of the flywheel 20 has a flywheel hole 2101 penetrating through opposite sides of the flywheel disc 211. The inner magnetic control device 10 is mounted in the flywheel space 213 of the flywheel body 21 of the flywheel 20, the housing hole 1101 of the housing 11 and the flywheel hole 2101 of the flywheel body 21 correspond to each other, wherein after one end of the mounting shaft 30 penetrates through the housing hole 1101 of the housing 11 and the flywheel hole 2101 of the flywheel body 21 in turn, the flange 40 is locked on the housing 11, and opposite ends of the mounting shaft 30 are fixedly mounted on the equipment rack 200 respectively, so that the inner magnetic control device 10 is fixedly arranged on the equipment rack 200. A user is allowed to drive the flywheel 20 to rotate relative to the inner magnetic control device 10 through the operation part 300, wherein in the process that the flywheel 20 rotates relative to the inner magnetic control device 10, the conductor 13 of the inner magnetic control device 10 cuts the magnetic induction lines in the middle of the magnetic field formed between the magnetic conductor 12 and the magnetic element 22, so that the flywheel 20 obtains a load, so that the fitness equipment can help the user achieve the purpose of fitness.

[0093] Now turning to the drawings Figure 4A The inner magnetic control device 10 further comprises a driving unit 14 arranged on the housing 11. The magnetic conductor 12 has a pivot end 121 and a driven end 122 corresponding to the pivot end 121, wherein the pivot end 121 of the magnetic conductor 12 is rotatably mounted on the housing 11, and the driven end 122 of the magnetic conductor 12 is drivably connected to the driving unit 14. The driving unit 14 is arranged to drive the magnetic conductor 12 to swing relative to the housing 11, so as to change the positions of the magnetic element 22 and the magnetic conductor 12, thereby changing the strength of the magnetic field formed between the magnetic element 22 and the magnetic conductor 12.

[0094] Preferably, the magnetic conductor 12 extends curvedly between the pivot end 121 and the driven end 122, so that the magnetic conductor 12 is arc-shaped, and the shape of the outer side of the magnetic conductor 12 is substantially the same as the shape of the periphery of the housing 11.

[0095] Preferably, the number of the magnetic conductors 12 of the inner magnetic control device 10 is two or more, and the two or more magnetic conductors 12 are arranged in central symmetry with the central axis of the flywheel assembly 100 as the axis of symmetry. For example, in the embodiment shown in FIG. 1, the number of the magnetic conductors 12 of the inner magnetic control device 10 is two, and the two magnetic conductors 12 are arranged in central symmetry with the central axis of the flywheel assembly 100 as the axis of symmetry. Figures 2A to 6In the specific example of the flywheel assembly 100 shown, the number of the magnetic conductors 12 of the inner magnetic control device 10 is two, and the two magnetic conductors 12 are arranged in a central symmetry with the central axis of the flywheel assembly 100 as the axis of symmetry. Alternatively, in other examples, the two magnetic conductors 12 are arranged in an axial symmetry.

[0096] With continued reference to the drawings Figure 4A The driving unit 14 is capable of simultaneously driving the two magnetic conductors 12 to swing with the same amplitude. Specifically, the driving unit 14 comprises a driving motor 141, a driving ring 142, and two connecting arms 143, wherein the driving motor 141 is mounted to the housing 11, wherein the driving ring 142 is rotatably mounted to the housing 11 and is drivably connected to the driving motor 141, wherein one end of each of the connecting arms 143 is rotatably mounted to each of the opposite sides of the driving ring 142, and the other end of each of the connecting arms 143 is rotatably mounted to the driven end 122 of each of the magnetic conductors 12. When the driving motor 141 drives the driving ring 142 to rotate around the central axis of the flywheel assembly 100, the driving ring 142 drives each of the magnetic conductors 12 to swing through each of the connecting arms 143, thereby changing the magnetic field strength formed between the magnetic elements 22 and the magnetic conductors 12.

[0097] Specifically, with reference to the drawings Figure 6 When the driving motor 141 drives the driving ring 142 to rotate clockwise, the driving ring 142 drives each of the magnetic conductors 12 to swing inward through each of the connecting arms 143, to allow each of the magnetic conductors 12 to swing from the maximum swing position to the minimum swing position, respectively. Correspondingly, when the driving motor 141 drives the driving ring 142 to rotate counterclockwise, the driving ring 142 drives each of the magnetic conductors 12 to swing outward through each of the connecting arms 143, to allow each of the magnetic conductors 12 to swing from the minimum swing position to the maximum swing position, respectively.

[0098] It can be understood that the flywheel assembly 100 forms the strongest magnetic field strength between the magnetic element 22 and the magnetic conductor 12 when each of the magnetic conductors 12 is at the maximum swing position, and correspondingly, the flywheel assembly 100 forms the weakest magnetic field strength between the magnetic element 22 and the magnetic conductor 12 when each of the magnetic conductors 12 is at the minimum swing position, thus, the flywheel assembly 100 forms the gradually weakened magnetic field strength between the magnetic element 22 and the magnetic conductor 12 when each of the magnetic conductors 12 swings from the maximum swing position to the minimum swing position, and correspondingly, the flywheel assembly 100 forms the gradually strengthened magnetic field strength between the magnetic element 22 and the magnetic conductor 12 when each of the magnetic conductors 12 swings from the minimum swing position to the maximum swing position.

[0099] With continued reference to the drawings Figures 3A to 4B The housing 11 further comprises a first disc-shaped shell 111 and a second disc-shaped shell 112, and has a shell space 1102, a peripheral opening 1103, and two communication passages 1104. The first shell 111 has a first ring body 1111, and the second shell 112 has a second ring body 1121. The first shell 111 and the second shell 112 are installed in a corresponding manner of the first ring body 1111 and the second ring body 1121, so that the shell space 1102 is formed at the inner side of the first ring body 1111 and the second ring body 1121, the peripheral opening 1103 is formed at the outer side of the first ring body 1111 and the second ring body 1121, and the communication passages 1104 are formed between the first ring body 1111 and the second ring body 1121, and the communication passages 1104 communicate the shell space 1102 and the peripheral opening 1103.

[0100] The opposite sides of the pivot end 121 of the magnet conductor 12 are rotatably mounted to the edges of the first housing 111 and the second housing 112, respectively, to rotatably mount the pivot end 121 of the magnet conductor 12 to the edges of the outer shell 11, and the magnet conductor 12 is allowed to swing in the peripheral opening 1103 of the outer shell 11. The opposite sides of the conductor 13 extend to and are fixed to the edges of the first housing 111 and the second housing 112, respectively, to dispose the conductor 13 in the outer shell 11 to hold the conductor 13 between the magnet conductor 12 and the magnetic element 22 by the outer shell 11. Preferably, the conductor 13 is annular, which surrounds the outside of the magnet conductor 12. The drive motor 141 and the drive ring 142 of the drive unit 14 are located in the housing space 1102 of the outer shell 11, respectively, and each of the link arms 143 extends from the housing space 1102 of the outer shell 11 to the peripheral opening 1103 through each of the communication passages 1104 of the outer shell 11, to allow one end portion of each of the link arms 143 to be rotatably mounted to each of the opposite sides of the drive ring 142, respectively, and to allow the other end portion of each of the link arms 143 to be rotatably mounted to the driven end 122 of each of the magnet conductors 12, respectively.

[0101] Further, the first housing 111 has a plurality of first mounting posts 1112 disposed outside the first ring body 1111, and the second housing 112 has a plurality of second mounting posts 1122 disposed outside the second ring body 1121, wherein each of the first mounting posts 1112 of the first housing 111 and each of the second mounting posts 1122 of the second housing 112 are mounted and supported to each other, respectively, to fixedly mount the first housing 111 and the second housing 112, and to avoid the edges of the first housing 111 and the edges of the second housing 112 from being deformed. Preferably, screws are allowed to be mounted to the first mounting posts 1112 of the first housing 111 and the second mounting posts 1122 of the second housing 112, to fixedly mount the first housing 111 and the second housing 112. Preferably, the first mounting posts 1112 of the first housing 111 are adjacent to the first ring body 1111, and the second mounting posts 1122 of the second housing 112 are adjacent to the second ring body 1121, to avoid the first mounting posts 1112 of the first housing 111 and the second mounting posts 1122 of the second housing 112 from affecting the magnet conductor 12 to swing to the minimum swing position.

[0102] Now turning to the drawings Figure 4AThe driving motor 141 of the driving unit 14 is fixedly mounted to the first housing 111 of the housing 11. The first housing 111 has a boss 1113, wherein the driving ring 142 is rotatably sleeved to the boss 1113 of the first housing 111, so that the driving ring 142 can rotate around the central axis of the flywheel assembly 100 when being driven by the driving motor 141 to drive the magnet conductor 12 to swing inwardly or outwardly.

[0103] Further, the driving unit 14 comprises a transmission gear set 144 for transmitting the power outputted by the output shaft 1411 of the driving motor 141 to the driving ring 142 to drive the driving ring 142 to rotate around the central axis of the flywheel assembly 100 relative to the housing 11 to drive the magnet conductor 12 to swing inwardly or outwardly.

[0104] Specifically, referring to the accompanying drawings, Figure 4A and Figure 6 The driving ring 142 has a row of first ring teeth 1421, wherein the transmission gear set 144 is composed of a plurality of meshing gears 1441, which are rotatably mounted to the first housing 111 and the second housing 112 in the housing space 1102 of the housing 11 respectively, wherein one of the gears 1441 is meshed with the output shaft 1411 of the driving motor 141, and another of the gears 1441 is meshed with the first ring teeth 1421 of the driving ring 142, so that when the driving motor 141 outputs power in the form of rotation of the output shaft 1411, the power can be transmitted to the driving ring 142 through the transmission gear set 144 to drive the driving ring 142 to rotate around the central axis of the flywheel assembly 100 relative to the housing 11 to drive the magnet conductor 12 to swing inwardly or outwardly.

[0105] It is worth mentioning that the number of the gears 1441 in the transmission gear set 144 is not limited in the flywheel assembly 100 of the present application. For example, in the specific example of the flywheel assembly 100 of the present application shown in the accompanying drawings, Figures 2A to 6 the number of the gears 1441 of the transmission gear set 144 is three.

[0106] Continuing to refer to the accompanying drawings, Figure 4A and Figure 6The driving unit 14 further comprises an auxiliary gear 145 rotatably mounted in the housing space 1102 of the housing 11, wherein the driving ring 142 has a second set of ring teeth 1422, and the second set of ring teeth 1422 of the driving ring 142 is engaged with the auxiliary gear 145 to avoid tilting of the driving ring 142 when the driving ring 142 is driven, thereby ensuring that the driving ring 142 stably and reliably rotates about the central axis of the flywheel assembly 100 relative to the housing 11.

[0107] With continued reference to the drawings Figure 4A and Figure 6 The inner magnetic control device 10 further comprises a potential control unit 15, which comprises a circuit board 151 and a rotary potentiometer 152 connected to the circuit board 151, and the driving motor 141 is connected to the circuit board 151, wherein the rotary potentiometer 152 has a mounting end 1521 and a rotating shaft end 1522 corresponding to the mounting end 1521, and the mounting end 1521 of the rotary potentiometer 152 is mounted to the first housing 111, and the auxiliary gear 145 is mounted to the rotating shaft end 1522 of the rotary potentiometer 152. When the driving motor 141 drives the driving ring 142 to rotate through each of the connecting arms 143 to swing each of the magnetic conductors 12 inwardly or outwardly, the driving ring 142 drives the auxiliary gear 145 to rotate, and at the same time, the auxiliary gear 145 drives the rotating shaft end 1522 of the rotary potentiometer 152 to rotate to change the resistance of the rotary potentiometer 152. It can be understood that the resistance of the rotary potentiometer 152 is related to the rotational position of the driving ring 142, and the rotational position of the driving ring 142 determines the swing position of the magnetic conductor 12, and further determines the load of the flywheel 20 when it is driven to rotate. In other words, the swing position of the magnetic conductor 12 and the load of the flywheel 20 when it is driven to rotate can be detected by detecting the resistance of the rotary potentiometer 152.

[0108] Preferably, the circuit board 151 of the potential control unit 15 is mounted to the first housing 111 of the housing 11. Preferably, the circuit board 151 is retained in the housing space 1102 of the housing 11 to hide the circuit board 151.

[0109] With continued reference to the drawings Figure 4A , Figure 4B and Figure 6The inner magnetic control device 10 further comprises two assemblies 16, one end of the linkage arm 143 of the driving unit 14 is rotatably mounted on the assembly 16, the assembly 16 is mounted on the driven end 122 of the magnetic conductor 12, so that one end of the linkage arm 143 is rotatably mounted on the driven end 122 of the magnetic conductor 12.

[0110] Preferably, the conductor 13 has two avoiding spaces 131 extending from the inner wall to the outer wall of the conductor 13, wherein the position of the avoiding space 131 of the conductor 13 corresponds to the assembly 16, so as to allow the conductor 13 to avoid the assembly 16 when the magnetic conductor 12 swings outward, thereby avoiding the assembly 16 affecting the magnetic conductor 12 to swing to the maximum swing position. Preferably, the avoiding space 131 of the conductor 13 extends from the inner wall to the outer wall of the conductor 13.

[0111] Now turning to the drawings Figure 3A , Figure 4A and Figure 6 The inner magnetic control device 10 further comprises at least one power generation unit 17, each of the power generation unit 17 respectively comprises a coil holder 171 and at least one coil 172 arranged on the coil holder 171, the coil holder 171 is arranged on the housing 11, the coil 172 is arranged adjacent to the magnetic element 22, so that when the flywheel 20 is driven to rotate relative to the inner magnetic control device 10, based on the principle of electromagnetic induction, the coil 172 can generate electric energy.

[0112] Preferably, the coil 172 of the power generation unit 17 is connected to the circuit board 151 of the potential control unit 15, so that the electric energy generated by the coil 172 can be provided to the driving motor 141 through the circuit board 151.

[0113] Preferably, the number of the power generation unit 17 is two, and the coil 172 of each of the power generation unit 17 is connected to the circuit board 151 of the potential control unit 15, so that the driving motor 141 can obtain sufficient electric energy to meet the working requirements.

[0114] Preferably, two power generation units 17 are symmetrically arranged. For example, in the drawings Figures 2A to 6In this specific example of the flywheel assembly 100 shown, each of the power generation units 17 is arranged in the space between the pivot end 121 of one of the magnetic conductors 12 and the driven end 122 of the adjacent one of the magnetic conductors 12, so that two of the power generation units 17 are symmetrically arranged. Moreover, the arrangement of the power generation units 17 in the space between the pivot end 121 of one of the magnetic conductors 12 and the driven end 122 of the adjacent one of the magnetic conductors 12 does not affect the magnetic field strength of the flywheel assembly 100.

[0115] With continued reference to the drawings Figure 4A and Figure 6 The coil holder 171 further comprises a holder body 1711 and at least one winding arm 1712 integrally extended from the holder body 1711, and the coil 172 is wound on the winding arm 1712, wherein the holder body 1711 is mounted on the first housing 111 of the housing 11, and the coil holder 171 is retained in the peripheral opening 1103 of the housing 11, so that the coil holder 171 allows the coil 172 to be retained adjacent to the magnetic element 22.

[0116] Preferably, the coil holder 171 comprises three winding arms 1712 integrally extended from the holder body 1711 at intervals, and the number of the coils 172 is three, and each of the winding arms 1712 of the coil holder 171 is wound with one of the coils 172, so that the driving motor 141 can obtain sufficient electric energy to meet the working requirements.

[0117] Now turning to the drawings Figure 4A and Figure 4B The conductor 13 has at least one through hole 132 extending from the inner wall to the outer wall of the conductor 13 to penetrate the opposite sides of the conductor 13, and the power generation unit 17 extends from the inner side to the outer side of the conductor 13 through the through hole 132 of the conductor 13, so that: on the one hand, the conductor 13 can avoid the power generation unit 17 to avoid affecting the size of the power generation unit 17, that is, the power generation unit 17 can be designed to have a larger size to improve the power generation capacity of the power generation unit 17, on the other hand, the conductor 13 can be implemented as a complete ring, so that the flywheel 20 has sufficient load when being driven to rotate relative to the inner magnetic control device 10.

[0118] With reference to the drawings Figure 7 A variant of the flywheel assembly 100 of the present application is shown, which is different from the flywheel assembly 100 shown in FIG. 1 in that Figures 2A to 6 The flywheel assembly 100 shown in FIG. 2 is different from the flywheel assembly 100 shown in FIG. 1 in that Figure 7In this specific example of the flywheel assembly 100 shown, the driving unit 14 further comprises at least one elastic element 146, an outer end of the elastic element 146 abutting against the magnet conductor 12, and an inner end of the elastic element 146 abutting against the housing 11, wherein when the flywheel 20 is driven to rotate relative to the inner magnetic control device 10, the elastic element 146 absorbs the vibration generated by the magnet conductor 12 to improve the stability of the flywheel assembly 100.

[0119] Preferably, in the accompanying drawings Figure 7 In this specific example of the flywheel assembly 100 of the present application shown, the connecting arm 143 is flexible, for example, the connecting arm 143 can be a pull rope. When the driving motor 141 drives the driving ring 142 to rotate clockwise through the transmission gear set 144, the driving ring 142 pulls the magnet conductor 12 to swing inward through the connecting arm 143, at this time, the elastic element 146 is extruded by the magnet conductor 12 and the housing 11 to produce elastic deformation to accumulate elastic potential energy. Correspondingly, when the driving motor 141 drives the driving ring 142 to rotate counterclockwise through the transmission gear set 144, the elastic element 146 pushes the magnet conductor 12 to swing outward in the process of restoring the initial state.

[0120] In the accompanying drawings Figures 8A to 11B A second specific example of the flywheel assembly 100 is shown, wherein the flywheel assembly 100 comprises an inner magnetic control device 10A and a flywheel 20A surrounding the inner magnetic control device 10A, the flywheel 20A is driven to be able to rotate relative to the inner magnetic control device 10A, so that the flywheel 20A obtains a load to help users use the fitness equipment for fitness.

[0121] Specifically, the flywheel 20A comprises a flywheel body 21A and at least one magnetic element 22A, wherein the flywheel body 21A comprises a disc 211A and a rim 212A extending from the edge of the disc 211A to the side of the disc 211A to form a flywheel space 213A between the disc 211A and the rim 212A, and the magnetic element 22A is arranged on the rim 212A of the flywheel body 21A, and the magnetic element 22A is located in the flywheel space 213A of the flywheel 21.

[0122] Now turning to the accompanying drawings Figures 8A to 11BThe inner magnetic control device 10A includes a housing 11A, at least one magnetic conductor 12A and at least one conductor 13A. The magnetic conductor 12A is movably arranged in the housing 11A, and the conductor 13A is arranged in the magnetic conductor 12A and outside the magnetic conductor 12A. The inner magnetic control device 10A is arranged in the flywheel space 213A of the flywheel body 21A, so that the conductor 13A is kept between the magnetic conductor 12A and the magnetic element 22A. When the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, the conductor 13A cuts the magnetic lines of the magnetic field formed between the magnetic element 22A and the magnetic conductor 12A to allow the flywheel 20A to obtain load, so that the user can achieve the purpose of fitness through the fitness equipment. By changing the position of the magnetic conductor 12A, the magnetic field strength formed between the magnetic element 22A and the magnetic conductor 12A is changed to adjust the load that the flywheel 20A can obtain, thereby helping the user to achieve different fitness effects using the fitness equipment.

[0123] In the fitness equipment, by arranging the magnetic element 22A in the flywheel body 21A, arranging the magnetic conductor 12A in the housing 11A and arranging the conductor 13A in the magnetic conductor 12A, first, the flywheel body 21A and the magnetic element 22A can jointly serve as the counterweight part of the flywheel 20A to reduce the cost of the flywheel assembly 100, second, when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, the conductor 13A cuts the magnetic lines in the middle of the magnetic field formed between the magnetic conductor 12A and the magnetic element 22A to make the flywheel 20A obtain load, thereby efficiently utilizing the magnetic field and reducing the requirement for the magnetic field strength, third, when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, the magnetic element 22A can be closely attached to the rim 212A of the flywheel body 21A under the action of centrifugal force to avoid the magnetic element 22A from falling off, and fourth, after the heat generated by the conductor 13A is radiated to the magnetic element 22A itself and the surrounding environment of the magnetic element 22A, the flywheel body 21A can quickly dissipate heat to reduce the temperature of the magnetic element 22A itself and the surrounding environment.

[0124] With reference to the accompanying drawings Figure 8A , Figure 8B , Figure 10A and Figure 10BThe flywheel assembly 100 further comprises a mounting shaft 30A and a flange 40A fixedly mounted to the mounting shaft 30A. The housing 11A of the inner magnetic control device 10A has a housing hole 1101A penetrating through opposite sides of the housing 11A. The flywheel body 21A of the flywheel 20A has a flywheel hole 2101A penetrating through opposite sides of the flywheel disc 211A. The inner magnetic control device 10A is mounted to the flywheel space 213A of the flywheel body 21A of the flywheel 20A, the housing hole 1101A of the housing 11A and the flywheel hole 2101A of the flywheel body 21A correspond to each other, wherein after a end of the mounting shaft 30A sequentially penetrates through the housing hole 1101A of the housing 11A and the flywheel hole 2101A of the flywheel body 21A, the flange 40A is locked to the housing 11A, wherein opposite ends of the mounting shaft 30A are fixedly mounted to the equipment rack 200, thus the inner magnetic control device 10A is fixedly arranged to the equipment rack 200. A user is allowed to drive the flywheel 20A to rotate relative to the inner magnetic control device 10A through the operation part 300, wherein during the flywheel 20A rotates relative to the inner magnetic control device 10A, the conductor 13A of the inner magnetic control device 10A cuts magnetic induction lines in the middle of a magnetic field formed between the magnetic conductor 12A and the magnetic element 22A, thus the flywheel 20A obtains load, thus the fitness equipment can help a user achieve fitness purpose.

[0125] The inner magnetic control device 10A further comprises a driving unit 14A arranged to the housing 11A. The magnetic conductor 12A has a pivot end 121A and a driven end 122A corresponding to the pivot end 121A, wherein the pivot end 121A of the magnetic conductor 12A is rotatably mounted to the housing 11A, the driven end 122A of the magnetic conductor 12A is drivably connected to the driving unit 14A. The driving unit 14A is arranged to drive the magnetic conductor 12A to swing relative to the housing 11A, to change the position of the magnetic element 22A and the magnetic conductor 12A, thus to change the magnetic field strength formed between the magnetic element 22A and the magnetic conductor 12A. It can be understood that when the driving unit 14A drives the magnetic conductor 12A to swing relative to the housing 11A, the magnetic conductor 12A drives the conductor 13A to swing synchronously.

[0126] Preferably, the magnetic conductor 12A extends curvedly between the pivot end 121A and the driven end 122A, thus the magnetic conductor 12A is arc-shaped, thus the shape of the outer side of the magnetic conductor 12A is substantially same as the shape of the periphery of the housing 11A.

[0127] Preferably, the conductor 13A is arc-shaped, and the arc of the conductor 13A and the arc of the magnetizer 12A are matched to allow the conductor 13A to be arranged on the magnetizer 12A in a manner that the conductor 13A and the magnetizer 12A are face-to-face.

[0128] It is worth mentioning that the arrangement of the conductor 13A on the magnetizer 12A is not limited in the flywheel assembly 100 of the present application. For example, glue can be used to bond the conductor 13A and the magnetizer 12A to arrange the conductor 13A on the magnetizer 12A, or the conductor 13A and the magnetizer 12A can be riveted to arrange the conductor 13A on the magnetizer 12A.

[0129] Preferably, the number of the magnetizers 12A and the number of the conductors 13A of the inner magnetic control device 10A are both more than two, and each of the magnetizers 12A is arranged on the outer side of the magnetizer 12A. For example, in the specific example of the flywheel assembly 100 shown in the accompanying drawings, the number of the magnetizers 12A and the number of the conductors 13A of the inner magnetic control device 10A are both two, and the two magnetizers 12A are arranged in a central symmetry with the central axis of the flywheel assembly 100 as the axis of symmetry. Alternatively, in other examples, the two magnetizers 12A are arranged in an axial symmetry. Figures 8A to 11B

[0130] Turning to the accompanying drawings, the flywheel assembly 100 of the present application is shown in the specific example of a flywheel assembly 100 of a treadmill. Figure 9A Figure 9B Figure 11A Figure 11B The inner magnetic control device 10A further comprises at least two flexible conductive elements 18A, and each of the conductive elements 18A is connected to the adjacent two conductors 13A to conductively connect the adjacent two conductors 13A by the conductive elements 18A. When the magnetizer 12A drives the conductor 13A to swing, the conductive elements 18A can be deformed to ensure that the conductive elements 18A are always conductively connected to the adjacent two conductors 13A. When the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, each of the conductors 13A will generate eddy current due to cutting magnetic induction lines, and the eddy currents generated by the conductors 13A can be balanced by the conductive elements 18A to conductively connect the adjacent two conductors 13A, which helps the flywheel 20 to rotate smoothly and reduces vibration, which is crucial for improving user experience and reducing vibration noise of the fitness equipment.

[0131] Now turning to the accompanying drawings, the flywheel assembly 100 of the present application is shown in the specific example of a flywheel assembly 100 of a treadmill. Figure 11A and​​​​Figure 11B The driving unit 14A is capable of simultaneously driving two of the magnetic conductors 12A to swing with the same amplitude. Specifically, the driving unit 14A comprises a driving motor 141A, a driving ring 142A, and two connecting arms 143A, wherein the driving motor 141A is mounted to the housing 11A, wherein the driving ring 142A is rotatably mounted to the housing 11A and is drivingly connected to the driving motor 141A, wherein each of the connecting arms 143A has one end rotatably mounted to each of the opposite sides of the driving ring 142A, and has the other end rotatably mounted to the driven end 122A of each of the magnetic conductors 12A. When the driving motor 141A drives the driving ring 142A to rotate around the central axis of the flywheel assembly 100, the driving ring 142A drives each of the magnetic conductors 12A to swing through each of the connecting arms 143A, thus changing the magnetic field strength formed between the magnetic element 22A and the magnetic conductor 12A.

[0132] Specifically, referring to the drawings, Figure 11A and Figure 11B When the driving motor 141A drives the driving ring 142A to rotate clockwise, the driving ring 142A drives each of the magnetic conductors 12A to swing inward through each of the connecting arms 143A, to allow each of the magnetic conductors 12A to swing from the maximum swing position to the minimum swing position, respectively, at which time the state of the conductive element 18A is automatically contracted with the inward swing of the magnetic conductor 12A. Correspondingly, when the driving motor 141A drives the driving ring 142A to rotate counterclockwise, the driving ring 142A drives each of the magnetic conductors 12A to swing outward through each of the connecting arms 143A, to allow each of the magnetic conductors 12A to swing from the minimum swing position to the maximum swing position, respectively, at which time the state of the conductive element 18A is automatically expanded with the outward swing of the magnetic conductor 12A.

[0133] It can be understood that when each of the magnetic conductors 12A is in the maximum swing position, the magnetic field strength formed between the magnetic element 22A and the magnetic conductor 12A of the flywheel assembly 100 is the strongest, and correspondingly, when each of the magnetic conductors 12A is in the minimum swing position, the magnetic field strength formed between the magnetic element 22A and the magnetic conductor 12A of the flywheel assembly 100 is the weakest, thus, when each of the magnetic conductors 12A swings from the maximum swing position to the minimum swing position, the magnetic field strength formed between the magnetic element 22A and the magnetic conductor 12A of the flywheel assembly 100 gradually weakens, and correspondingly, when each of the magnetic conductors 12A swings from the minimum swing position to the maximum swing position, the magnetic field strength formed between the magnetic element 22A and the magnetic conductor 12A of the flywheel assembly 100 gradually strengthens.

[0134] With continued reference to the drawings Figures 9A to 10B The housing 11A further comprises a first disc-shaped housing 111A and a second disc-shaped housing 112A, and has a housing space 1102A, a peripheral opening 1103A, and two communication passages 1104A. The first housing 111A has a first ring body 1111A, and the second housing 112A has a second ring body 1121A. The first housing 111A and the second housing 112A are installed in a corresponding manner with the first ring body 1111A and the second ring body 1121A, so that the housing space 1102A is formed inside the first ring body 1111A and the second ring body 1121A, the peripheral opening 1103A is formed outside the first ring body 1111A and the second ring body 1121A, and the communication passages 1104A are formed between the first ring body 1111A and the second ring body 1121A, and the communication passages 1104A communicate the housing space 1102A and the peripheral opening 1103A.

[0135] The opposite sides of the pivot end 121A of the magnetic conductor 12A are rotatably mounted to the edges of the first housing 111A and the second housing 112A, respectively, to rotatably mount the pivot end 121A of the magnetic conductor 12A to the edges of the housing 11A, and the magnetic conductor 12A is allowed to swing at the peripheral opening 1103A of the housing 11A. The driving motor 141A and the driving ring 142A of the driving unit 14A are located at the housing space 1102A of the housing 11A, respectively, and each of the linkage arms 143A extends from the housing space 1102A of the housing 11A to the peripheral opening 1103A through each of the communication passages 1104A of the housing 11A, to rotatably mount one end of each of the linkage arms 143A to each of the opposite sides of the driving ring 142A, and to rotatably mount the other end of each of the linkage arms 143A to the driven end 122A of each of the magnetic conductors 12A, respectively.

[0136] Further, the first housing 111A has a plurality of first mounting posts 1112A disposed outside the first ring body 1111A, and the second housing 112A has a plurality of second mounting posts 1122A disposed outside the second ring body 1121A, wherein each of the first mounting posts 1112A of the first housing 111A and each of the second mounting posts 1122A of the second housing 112A are mounted and supported to each other, to fixedly mount the first housing 111A and the second housing 112A, and to avoid the first housing 111A and the second housing 112A from being deformed. Preferably, screws are allowed to be mounted to the first mounting posts 1112A of the first housing 111A and the second mounting posts 1122A of the second housing 112A, to fixedly mount the first housing 111A and the second housing 112A. Preferably, the first mounting posts 1112A of the first housing 111A are adjacent to the first ring body 1111A, and the second mounting posts 1122A of the second housing 112A are adjacent to the second ring body 1121A, to avoid the first mounting posts 1112A of the first housing 111A and the second mounting posts 1122A of the second housing 112A from affecting the swinging of the magnetic conductors 12A to the minimum swing position.

[0137] Now turning to the drawings Figure 9A , Figures 9A to 11BThe driving motor 141A of the driving unit 14A is fixedly mounted to the first housing 111A of the housing 11A. The first housing 111A has a boss 1113A, wherein the driving ring 142A is rotatably sleeved to the boss 1113A of the first housing 111A, so that the driving ring 142A can rotate around the central axis of the flywheel assembly 100 when being driven by the driving motor 141A to drive the magnet conductor 12A to swing inwardly or outwardly.

[0138] Further, the driving unit 14A comprises a transmission gear set 144A for transmitting the power outputted by the output shaft 1411A of the driving motor 141A to the driving ring 142A to drive the driving ring 142A to rotate around the central axis of the flywheel assembly 100 relative to the housing 11A to drive the magnet conductor 12A to swing inwardly or outwardly.

[0139] In particular, referring to the accompanying drawings Figure 9A , Figure 11A and Figure 11B , the driving ring 142A has a row of first ring teeth 1421A, wherein the transmission gear set 144A is composed of a plurality of meshed gears 1441A, which are rotatably mounted to the first housing 111A and the second housing 112A in the housing space 1102A of the housing 11A respectively, wherein one of the gears 1441A is meshed with the output shaft 1411A of the driving motor 141A, and another of the gears 1441A is meshed with the first ring teeth 1421A of the driving ring 142A, so that when the driving motor 141A outputs power in the form of rotation of the output shaft 1411A, the power can be transmitted to the driving ring 142A through the transmission gear set 144A to drive the driving ring 142A to rotate around the central axis of the flywheel assembly 100 relative to the housing 11A to drive the magnet conductor 12A to swing inwardly or outwardly.

[0140] It is worth mentioning that the number of the gears 1441A in the transmission gear set 144A is not limited in the flywheel assembly 100 of the present application. For example, in the specific example of the flywheel assembly 100 of the present application shown in the accompanying drawings Figures 8A to 11B , the number of the gears 1441A of the transmission gear set 144A is three.

[0141] Continuing to refer to the accompanying drawings Figure 9A , Figure 11A and Figure 11BThe driving unit 14A further comprises an auxiliary gear 145A rotatably mounted in the housing space 1102A of the housing 11 A, wherein the driving ring 142A has a second set of ring teeth 1422A, and the second set of ring teeth 1422A of the driving ring 142A is engaged with the auxiliary gear 145A to avoid the driving ring 142A from tilting when the driving ring 142A is driven, so as to ensure that the driving ring 142A stably and reliably rotates around the central axis of the flywheel assembly 100 relative to the housing 11 A.

[0142] With reference to the accompanying drawings Figure 9A , Figure 11A and Figure 11B The inner magnetic control device 10A further comprises a potential control unit 15A, which comprises a circuit board 151A and a rotary potentiometer 152A connected to the circuit board 151A, and the driving motor 141A is connected to the circuit board 151A, wherein the rotary potentiometer 152A has a mounting end 1521A and a rotating shaft end 1522A corresponding to the mounting end 1521A, and the mounting end 1521A of the rotary potentiometer 152A is mounted on the first housing 111A, and the auxiliary gear 145A is mounted on the rotating shaft end 1522A of the rotary potentiometer 152A. When the driving motor 141A drives each of the magnetic conductors 12A to swing inwards or outwards through each of the connecting arms 143A by driving the driving ring 142A to rotate, the driving ring 142A drives the auxiliary gear 145A to rotate, and at the same time, the auxiliary gear 145A drives the rotating shaft end 1522A of the rotary potentiometer 152A to rotate to change the resistance of the rotary potentiometer 152A. It can be understood that the resistance of the rotary potentiometer 152A is related to the rotating position of the driving ring 142A, and the rotating position of the driving ring 142A determines the swinging position of the magnetic conductor 12A, and further determines the load of the flywheel 20A when it is driven to rotate. In other words, the swinging position of the magnetic conductor 12A and the load of the flywheel 20A when it is driven to rotate can be detected by detecting the resistance of the rotary potentiometer 152A.

[0143] Preferably, the circuit board 151A of the potential control unit 15A is mounted on the first housing 111A of the housing 11A. Preferably, the circuit board 151A is retained in the housing space 1102A of the housing 11A to hide the circuit board 151A.

[0144] With reference to the accompanying drawings Figure 9A , Figure 11A and Figure 11BThe inner magnetic control device 10A further comprises two sets of assemblies 16A, the end of the linkage arm 143A of the driving unit 14A is rotatably mounted to the assemblies 16A, the assemblies 16A are mounted to the driven end 122A of the magnetic conductor 12A, and the end of the linkage arm 143A is rotatably mounted to the driven end 122A of the magnetic conductor 12A.

[0145] Preferably, the conductor 13A has two avoiding spaces 131A extending from the inner wall to the outer wall of the conductor 13A, wherein the avoiding spaces 131A of the conductor 13A are located corresponding to the assemblies 16A, so as to allow the conductor 13A to avoid the assemblies 16A when the magnetic conductor 12A swings outward, thereby avoiding the assemblies 16A affecting the magnetic conductor 12A to swing to the maximum swing position. Preferably, the avoiding spaces 131A of the conductor 13A extend from the inner wall to the outer wall of the conductor 13A.

[0146] The inner magnetic control device 10A further comprises two sets of assemblies 16A, the end of the linkage arm 143A of the driving unit 14A is rotatably mounted to the assemblies 16A, the assemblies 16A are mounted to the driven end 122A of the magnetic conductor 12A, and the end of the linkage arm 143A is rotatably mounted to the driven end 122A of the magnetic conductor 12A. Figure 12A And Figure 12B A variant of the flywheel assembly 100 of the present application is shown in FIG. 6, which is different from the flywheel assembly 100 shown in FIG. 1 in that the inner magnetic control device 10A of the flywheel assembly 100 shown in FIG. 6 has two sets of assemblies 16A, the end of the linkage arm 143A of the driving unit 14A is rotatably mounted to the assemblies 16A, the assemblies 16A are mounted to the driven end 122A of the magnetic conductor 12A, and the end of the linkage arm 143A is rotatably mounted to the driven end 122A of the magnetic conductor 12A. Figures 8A to 11B The flywheel assembly 100 shown in FIG. 6 is different from the flywheel assembly 100 shown in FIG. 1 in that the inner magnetic control device 10A of the flywheel assembly 100 shown in FIG. 6 has two sets of assemblies 16A, the end of the linkage arm 143A of the driving unit 14A is rotatably mounted to the assemblies 16A, the assemblies 16A are mounted to the driven end 122A of the magnetic conductor 12A, and the end of the linkage arm 143A is rotatably mounted to the driven end 122A of the magnetic conductor 12A. Figure 12A And Figure 12B In this specific example of the flywheel assembly 100 shown in FIG. 6, the electrically conductive element 18A of the inner magnetic control device 10A is rigid, and one end of the electrically conductive element 18A is rotatably mounted to the end of one of the conductors 13A, and the other end of the electrically conductive element 18A is rotatably mounted to the end of the adjacent conductor 13A. When the magnetic conductor 12A drives the conductors 13A to swing, the electrically conductive element 18A can rotate relative to the conductors 13A to ensure that the electrically conductive element 18A is always electrically connected to the adjacent two conductors 13A. When the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, eddy currents will be generated in each of the conductors 13A due to cutting magnetic induction lines, and the eddy currents generated in the conductors 13A can be balanced through the electrically conductive element 18A electrically connecting the adjacent two conductors 13A, which helps the flywheel 20 to rotate smoothly and reduces vibration, which is crucial for improving user experience and reducing vibration noise of the fitness equipment.

[0147] Further, the conductive element 18A includes a first conductive segment 181 A and a second conductive segment 182A, one end of the first conductive segment 181 A and one end of the second conductive segment 182A are rotatably mounted, the other end of the first conductive segment 181 A is rotatably mounted to one end of the conductor 13A, the other end of the second conductive segment 182A is rotatably mounted to the other end of the conductor 13A, so that the flexibility of the conductive element 18A can be greatly improved, thereby avoiding the situation that the mounting position of the conductive element 18A and the conductor 13A is stuck when the magnet conductor 12A drives the conductor 13A to swing. Optionally, in other examples of the flywheel assembly 100 of the application, the conductive segment of the conductive element 18A can be more than three.

[0148] attached Figures 13 to 17B A third specific example of the flywheel assembly 100 is shown, wherein the flywheel assembly 100 includes an inner magnetic control device 10B and a flywheel 20B surrounding the inner magnetic control device 10B, the flywheel 20B is driven to rotate relative to the inner magnetic control device 10B, so that the flywheel 20B obtains a load to help users use the fitness equipment for fitness.

[0149] In particular, the flywheel 20B includes a flywheel body 21B and at least one magnetic element 22B, wherein the flywheel body 21B includes a disc 211B and a rim 212B extending from the edge of the disc 211B to the side of the disc 211B to form a flywheel space 213B between the disc 211B and the rim 212B, and the magnetic element 22B is arranged on the rim 212B of the flywheel body 21B, and the magnetic element 22B is located in the flywheel space 213B of the flywheel body 21B.

[0150] Now turning to the drawings Figures 13 to 17BThe inner magnetic control device 10B includes a housing 11B, at least one magnetic conductor 12B and at least one conductor 13B. The magnetic conductor 12B is movably arranged in the housing 11B. The conductor 13B is arranged in the magnetic conductor 12B and outside the magnetic conductor 12B. The inner magnetic control device 10B is arranged in the flywheel space 213B of the flywheel body 21B, so that the conductor 13B is kept between the magnetic conductor 12B and the magnetic element 22B. When the flywheel 20B is driven to rotate relative to the inner magnetic control device 10B, the conductor 13B cuts the magnetic lines of the magnetic field formed between the magnetic element 22B and the magnetic conductor 12B, so that the flywheel 20B can obtain load, and thus the user can achieve the purpose of fitness through the fitness equipment. By changing the position of the magnetic conductor 12B, the magnetic field strength formed between the magnetic element 22B and the magnetic conductor 12B is changed, so as to adjust the load that the flywheel 20B can obtain, thereby helping the user to achieve different fitness effects by using the fitness equipment.

[0151] In the fitness equipment, by arranging the magnetic element 22B in the flywheel body 21B, arranging the magnetic conductor 12B in the housing 11B and arranging the conductor 13B in the magnetic conductor 12B, first, the flywheel body 21B and the magnetic element 22B can jointly serve as the counterweight part of the flywheel 20B, so as to reduce the cost of the flywheel assembly 100. Second, when the flywheel 20B is driven to rotate relative to the inner magnetic control device 10B, the conductor 13B cuts the magnetic lines in the middle of the magnetic field formed between the magnetic conductor 12B and the magnetic element 22B, so that the flywheel 20B can obtain load, thereby efficiently utilizing the magnetic field and reducing the requirement for the magnetic field strength. Third, when the flywheel 20B is driven to rotate relative to the inner magnetic control device 10B, the magnetic element 22B can be closely attached to the rim 212B of the flywheel body 21B under the action of centrifugal force, so as to avoid the magnetic element 22B from falling off. Fourth, after the heat generated by the conductor 13B is radiated to the magnetic element 22B itself and the surrounding environment of the magnetic element 22B, the flywheel body 21B can quickly dissipate heat, so as to reduce the temperature of the magnetic element 22B itself and the surrounding environment.

[0152] With reference to the accompanying drawings Figures 13 to 17BThe inner magnetic control device 10B further comprises a driving unit 14B arranged in the housing 11B. The magnetic conductor 12B has a pivot end 121B and a driven end 122B corresponding to the pivot end 121B, wherein the pivot end 121B of the magnetic conductor 12B is rotatably mounted on the housing 11B, and the driven end 122B of the magnetic conductor 12B is drivingly connected to the driving unit 14B. The driving unit 14B is arranged to drive the magnetic conductor 12B to swing relative to the housing 11B, so as to change the positions of the magnetic element 22B and the magnetic conductor 12B, thereby changing the magnetic field strength formed between the magnetic element 22B and the magnetic conductor 12B. It can be understood that when the driving unit 14B drives the magnetic conductor 12B to swing relative to the housing 11B, the magnetic conductor 12B drives the conductor 13B to swing synchronously.

[0153] Preferably, the magnetic conductor 12B is curvedly extended between the pivot end 121B and the driven end 122B, so that the magnetic conductor 12B is arc-shaped. In this way, the shape of the outer side of the magnetic conductor 12B is substantially the same as the shape of the periphery of the housing 11B.

[0154] Preferably, the conductor 13B is arc-shaped, and the curvature of the conductor 13B matches the curvature of the magnetic conductor 12B, so as to allow the conductor 13B to be arranged on the magnetic conductor 12B in a manner that the conductor 13B and the magnetic conductor 12B are surface-to-surface adhered.

[0155] It is worth mentioning that the arrangement of the conductor 13B on the magnetic conductor 12B is not limited in the flywheel assembly 100 of the present application. For example, glue can be used to bond the conductor 13B and the magnetic conductor 12B, so as to arrange the conductor 13B on the magnetic conductor 12B, or the conductor 13B and the magnetic conductor 12B can be riveted, so as to arrange the conductor 13B on the magnetic conductor 12B.

[0156] Preferably, the number of the magnetic conductors 12B and the number of the conductors 13B of the inner magnetic control device 10B are both two or more, one of the conductors 13B is arranged on the outer side of each of the magnetic conductors 12B, and two or more of the magnetic conductors 12B are arranged in a central symmetry manner with the central axis of the flywheel assembly 100 as the axis of symmetry. For example, in the specific example of the flywheel assembly 100 shown in the accompanying drawings, the number of the magnetic conductors 12B and the number of the conductors 13B of the inner magnetic control device 10B are both two, and two of the magnetic conductors 12B are arranged in a central symmetry manner with the central axis of the flywheel assembly 100 as the axis of symmetry. Alternatively, in other examples, two of the magnetic conductors 12B are arranged in an axial symmetry manner. Figures 13 to 17B Preferably, the number of the magnetic conductors 12B and the number of the conductors 13B of the inner magnetic control device 10B are both two or more, one of the conductors 13B is arranged on the outer side of each of the magnetic conductors 12B, and two or more of the magnetic conductors 12B are arranged in a central symmetry manner with the central axis of the flywheel assembly 100 as the axis of symmetry. For example, in the specific example of the flywheel assembly 100 shown in the accompanying drawings, the number of the magnetic conductors 12B and the number of the conductors 13B of the inner magnetic control device 10B are both two, and two of the magnetic conductors 12B are arranged in a central symmetry manner with the central axis of the flywheel assembly 100 as the axis of symmetry. Alternatively, in other examples, two of the magnetic conductors 12B are arranged in an axial symmetry manner.

[0157] With reference to the drawings Figures 13 to 17B The driving unit 14B is capable of driving both of the magnet conductors 12B to swing at the same amplitude simultaneously. Specifically, the driving unit 14B comprises a driving motor 141B, a driving ring 142B and two connecting arms 143B, wherein the driving motor 141B is mounted on the housing 11B, wherein the driving ring 142B is rotatably mounted on the housing 11B and is drivingly connected to the driving motor 141B, wherein one end of each of the connecting arms 143B is rotatably mounted on each of the opposite sides of the driving ring 142B respectively, and the other end of each of the connecting arms 143B is rotatably mounted on the driven end 122B of each of the magnet conductors 12B respectively. When the driving motor 141B drives the driving ring 142B to rotate around the central axis of the flywheel assembly 100, the driving ring 142B drives each of the magnet conductors 12B to swing through each of the connecting arms 143B respectively, thus changing the magnetic field strength formed between the magnetic element 22B and the magnet conductor 12B.

[0158] Specifically, with reference to the drawings Figure 17A and Figure 17B When the driving motor 141B drives the driving ring 142B to rotate clockwise, the driving ring 142B drives each of the magnet conductors 12B to swing inward through each of the connecting arms 143B respectively, to allow each of the magnet conductors 12B to swing from the maximum swing position to the minimum swing position respectively, and correspondingly, when the driving motor 141B drives the driving ring 142B to rotate counterclockwise, the driving ring 142B drives each of the magnet conductors 12B to swing outward through each of the connecting arms 143B respectively, to allow each of the magnet conductors 12B to swing from the minimum swing position to the maximum swing position respectively.

[0159] It can be understood that when each of the magnet conductors 12B is at the maximum swing position, the flywheel assembly 100 forms the strongest magnetic field strength between the magnetic element 22B and the magnet conductor 12B, and correspondingly, when each of the magnet conductors 12B is at the minimum swing position, the flywheel assembly 100 forms the weakest magnetic field strength between the magnetic element 22B and the magnet conductor 12B, therefore, when each of the magnet conductors 12B swings from the maximum swing position to the minimum swing position respectively, the flywheel assembly 100 gradually weakens the magnetic field strength between the magnetic element 22B and the magnet conductor 12B, and correspondingly, when each of the magnet conductors 12B swings from the minimum swing position to the maximum swing position respectively, the flywheel assembly 100 gradually strengthens the magnetic field strength between the magnetic element 22B and the magnet conductor 12B.

[0160] Continue to refer to the attached Figures 13 to 17B The housing 11B further includes a disc-shaped first shell 111B and a disc-shaped second shell 112B, and has a shell space 1102B, a peripheral opening 1103B and two communication channels 1104B. The first shell 111B has a first ring body 1111B, and the second shell 112B has a second ring body 1121B, wherein the first shell 111B and the second shell 112B are installed with each other in a manner corresponding to the first ring body 1111B and the second ring body 1121B, so as to form the shell space 1102B on the inner side of the first ring body 1111B and the second ring body 1121B, form the peripheral opening 1103B on the outer side of the first ring body 1111B and the second ring body 1121B, and form the connecting channel 1104B between the first ring body 1111B and the second ring body 1121B, and the connecting channel 1104B connects the shell space 1102B and the peripheral opening 1103B.

[0161] The opposite sides of the pivot end 121B of the magnet 12B are rotatably mounted on the edge of the first shell 111B and the edge of the second shell 112B, respectively, so as to rotatably mount the pivot end 121B of the magnet 12B on the edge of the outer shell 11B, and the magnet 12B is allowed to swing in the peripheral opening 1103B of the outer shell 11B. The driving motor 141B and the driving ring 142B of the driving unit 14B are respectively located in the shell space 1102B of the shell 11B, and each of the linkage arms 143B respectively extends from the shell space 1102B of the shell 11B to the peripheral opening 1103B through each of the connecting channels 1104B of the shell 11B, so as to allow one end of each linkage arm 143B to be rotatably mounted on each side of the opposite sides of the driving ring 142B, and to allow the other end of each linkage arm 143B to be rotatably mounted on the driven end 122B of each of the magnetizers 12B.

[0162] Further, the first housing 111B has a plurality of first mounting posts 1112B disposed on the outer side of the first ring body 1111B, and the second housing 112B has a plurality of second mounting posts 1122B disposed on the outer side of the second ring body 1121B, wherein each of the first mounting posts 1112B of the first housing 111B and each of the second mounting posts 1122B of the second housing 112B are mounted and supported with each other to fixedly mount the first housing 111B and the second housing 112B and to avoid the first housing 111B and the second housing 112B from being deformed. Preferably, screws are allowed to be mounted on the first mounting posts 1112B of the first housing 111B and the second mounting posts 1122B of the second housing 112B to fixedly mount the first housing 111B and the second housing 112B. Preferably, the first mounting posts 1112B of the first housing 111B are adjacent to the first ring body 1111B, and the second mounting posts 1122B of the second housing 112B are adjacent to the second ring body 1121B to avoid the first mounting posts 1112B of the first housing 111B and the second mounting posts 1122B of the second housing 112B from affecting the magnet conductor 12B to swing to the minimum swing position.

[0163] Now turning to the drawings Figures 13 to 17B The driving motor 141B of the driving unit 14B is fixedly mounted on the first housing 111B of the outer shell 11B. The first housing 111B has a boss 1113B, wherein the driving ring 142B is rotatably sleeved on the boss 1113B of the first housing 111B, so that the driving ring 142B can rotate around the central axis of the flywheel assembly 100 when being driven by the driving motor 141B to drive the magnet conductor 12B to swing inwardly or outwardly.

[0164] Further, the driving unit 14B comprises a transmission gear set 144B for transmitting power output by the output shaft 1411B of the driving motor 141B to the driving ring 142B to drive the driving ring 142B to rotate around the central axis of the flywheel assembly 100 relative to the outer shell 11B to drive the magnet conductor 12B to swing inwardly or outwardly.

[0165] In particular, reference is made to the drawings Figures 13 to 17BThe drive ring 142B has a row of first ring teeth 1421B, wherein the transmission gear set 144B is composed of a plurality of meshing gears 1441B, and these gears 1441B are rotatably mounted on the first shell 111B and the second shell 112B in the shell space 1102B of the housing 11B, wherein one of the gears 1441B is meshed with the output shaft 1411B of the drive motor 141B, and these gears 1441B are meshed with the output shaft 1411B of the drive motor 141B. The other gear 1441B in 1B is engaged with the first ring tooth 1421B of the drive ring 142B, so that when the drive motor 141B outputs power by rotating the output shaft 1411B of the drive motor 141B, the power can be transmitted to the drive ring 142B through the transmission gear set 144B to drive the drive ring 142B to rotate around the central axis of the flywheel assembly 100 relative to the housing 11B, thereby driving the magnet 12B to swing inward or outward.

[0166] It is worth mentioning that the number of the gears 1441B in the transmission gear set 144B is not limited in the flywheel assembly 100 of the present invention. Figures 13 to 15 In the particular example of the flywheel assembly 100 of the present invention shown, the number of the gears 1441B of the transmission gear set 144B is three.

[0167] Continue to refer to the attached Figures 13 to 17B The drive unit 14B further includes an auxiliary gear 145B, which is rotatably mounted in the shell space 1102B of the housing 11B, wherein the drive ring 142B has a row of second ring teeth 1422B, and the second ring teeth 1422B of the drive ring 142B are engaged with the auxiliary gear 145B to prevent the drive ring 142B from tilting when the drive ring 142B is driven, thereby ensuring that the drive ring 142B stably and reliably rotates around the central axis of the flywheel assembly 100 relative to the housing 11B.

[0168] Continue to refer to the attached Figures 13 to 17BThe inner magnetic control device 10B further comprises a potential control unit 15B, the potential control unit 15B comprises a circuit board 151B and a rotary potentiometer 152B connected to the circuit board 151B, the driving motor 141B is connected to the circuit board 151B, wherein the rotary potentiometer 152B has a mounting end 1521B and a shaft end 1522B corresponding to the mounting end 1521B, the mounting end 1521B of the rotary potentiometer 152B is mounted to the first shell 111B, and the auxiliary gear 145B is mounted to the shaft end 1522B of the rotary potentiometer 152B. When each of the magnetic conductors 12B is swung inwards or outwards by the driving motor 141B through the driving of the driving ring 142B to swing each of the driving arms 143B, the driving ring 142B drives the auxiliary gear 145B to rotate, and at the same time, the auxiliary gear 145B drives the shaft end 1522B of the rotary potentiometer 152B to rotate to change the resistance of the rotary potentiometer 152B. It can be understood that the resistance of the rotary potentiometer 152B is related to the rotating position of the driving ring 142B, and the rotating position of the driving ring 142B determines the swinging position of the magnetic conductor 12B, and further determines the load of the flywheel 20B when being driven to rotate. In other words, the swinging position of the magnetic conductor 12B and the load of the flywheel 20B when being driven to rotate can be detected by detecting the resistance of the rotary potentiometer 152B.

[0169] Preferably, the circuit board 151B of the potential control unit 15B is mounted to the first shell 111B of the outer shell 11B. Preferably, the circuit board 151B is retained in the shell space 1102B of the outer shell 11B to hide the circuit board 151B.

[0170] Continuing to refer to the drawings Figures 13 to 17B The inner magnetic control device 10B further comprises two assemblies 16B, the end of the driving arm 143B of the driving unit 14B is rotatably mounted to the assembly 16B, and the assembly 16B is mounted to the driven end 122B of the magnetic conductor 12B, so that the end of the driving arm 143B is rotatably mounted to the driven end 122B of the magnetic conductor 12B.

[0171] Preferably, the conductor 13B has two avoiding spaces 131B extending from the inner wall to the outer wall of the conductor 13B, wherein the positions of the avoiding spaces 131B of the conductor 13B correspond to the assembly 16B, so as to allow the conductor 13B to avoid the assembly 16B when the magnet conductor 12B swings outward, thereby avoiding the assembly 16B from affecting the magnet conductor 12B to swing to the maximum swing position. Preferably, the avoiding spaces 131B of the conductor 13B extend from the inner wall to the outer wall of the conductor 13B.

[0172] With reference to the accompanying drawings Figures 13 to 17B The adjacent conductors 13B of the inner magnetic control device 10B are electrically conductive connected through the shell 11B, and the shell 11B is always electrically conductive connected to the adjacent conductors 13B when the magnet conductor 12B swings the conductors 13B. When the flywheel 20B is driven to rotate relative to the inner magnetic control device 10B, eddy currents are generated in each of the conductors 13B due to cutting magnetic induction lines, and the eddy currents generated by the adjacent two conductors 13B are balanced through the shell 11B to electrically conductive connect the two conductors 13B, thereby helping the flywheel 20B to rotate smoothly and reducing vibration, which is crucial for improving user experience and reducing vibration noise of the fitness equipment.

[0173] Further, the shell 11B has at least two pairs of electrically conductive grooves 113B, each pair of electrically conductive grooves 113B is composed of a first electrically conductive groove 1131B and a second electrically conductive groove 1132B adjacent to each other, wherein the conductor 13B has at least a first electrically conductive column 132B at the end corresponding to the driven end 122B of the magnet conductor 12B, the first electrically conductive column 132B is slidably installed in the first electrically conductive groove 1131B of the shell 11B, and the first electrically conductive column 132B of the conductor 13B contacts the inner wall of the shell 11B for forming the first electrically conductive groove 1131B, wherein the conductor 13B has at least a second electrically conductive column 133B at the end corresponding to the pivot end 121B of the magnet conductor 12B, the second electrically conductive column 133B is slidably installed in the second electrically conductive groove 1132B of the shell 11B, and the second electrically conductive column 133B of the conductor 13B contacts the inner wall of the shell 11B for forming the second electrically conductive groove 1132B, so that the shell 11B can reliably electrically conductive connect the adjacent two conductors 13B.

[0174] With reference to the accompanying drawings Figure 17A and Figure 17BWhen the driving motor 141B drives the driving ring 142B to rotate clockwise, the driving ring 142B drives each of the magnet conductors 12B to swing inwardly through each of the connecting arms 143B to allow each of the magnet conductors 12B to swing from the maximum swing position to the minimum swing position respectively, and when each of the magnet conductors 12B swings from the maximum swing position to the minimum swing position respectively, the first conductive column 132B of the conductor 13B slides along the track formed by the first conductive recess 1131B of the housing 11B in a manner that always contacts the inner wall of the housing 11B for forming the first conductive recess 1131B, and the second conductive column 133B of the conductor 13B slides along the track formed by the second conductive recess 1132B of the housing 11B in a manner that always contacts the inner wall of the housing 11B for forming the second conductive recess 1132B. Correspondingly, when the driving motor 141B drives the driving ring 142B to rotate counterclockwise, the driving ring 142B drives each of the magnet conductors 12B to swing outwardly through each of the connecting arms 143B to allow each of the magnet conductors 12B to swing from the minimum swing position to the maximum swing position respectively, and when each of the magnet conductors 12B swings from the minimum swing position to the maximum swing position respectively, the first conductive column 132B of the conductor 13B slides along the track formed by the first conductive recess 1131B of the housing 11B in a manner that always contacts the inner wall of the housing 11B for forming the first conductive recess 1131B, and the second conductive column 133B of the conductor 13B slides along the track formed by the second conductive recess 1132B of the housing 11B in a manner that always contacts the inner wall of the housing 11B for forming the second conductive recess 1132B.

[0175] Now turning to the drawings Figures 13 to 17B The housing 11B further comprises at least two conductive portions 114B, the conductive portions 114B are installed to the first housing 111B, each pair of the conductive grooves 113B is formed in each of the conductive portions 114B to conductively connect two adjacent conductors 13B by the conductive portions 114B.
