Description

TECHNICAL FIELD

[0001] The present application relates to a fitness equipment, in particular to a flywheel assembly and a flywheel thereof. BACKGROUND

[0002] The flywheel assembly is a key part of the fitness equipment (for example, a spinning bike, an elliptical machine), the existing flywheel assembly includes an inner magnetic control device and a flywheel surrounding the inner magnetic control device, the inner magnetic control device provides a position swingable magnetic guide and a magnetic element arranged on the magnetic guide, the flywheel provides a conductor, when the flywheel is driven to rotate relative to the inner magnetic control device, the conductor arranged on the flywheel cuts the magnetic induction lines of the inner magnetic control device to obtain a load, so as to allow the user to achieve the purpose of fitness by using the fitness equipment. In the process of allowing the flywheel to obtain the load by cutting the magnetic induction lines of the inner magnetic control device by the conductor arranged on the flywheel, a large amount of heat is generated, and the heat gathered around the inner magnetic control device can cause the temperature inside the inner magnetic control device to rise. Since the inner magnetic control device has a circuit board inside and a large number of electronic components (for example, processors, resistors, capacitors, Hall elements, etc.) are attached on the circuit board, the temperature rise of the inner magnetic control device will inevitably cause the working environment of these electronic components to become poor and affect their performance and service life. In addition, the magnetic guide and the magnetic element of the existing flywheel assembly are located on the inner side of the conductor of the flywheel, and the magnetic field of the inner magnetic control device is mainly concentrated between the magnetic guide and the magnetic element, which means that the conductor of the flywheel is located at the edge of the magnetic field of the inner magnetic control device. That is, when the flywheel drives the conductor to rotate relative to the inner magnetic control device, the conductor can only cut the magnetic induction lines of the inner magnetic control device at the edge of the magnetic field of the inner magnetic control device to obtain the load, which results in that the flywheel assembly has low utilization rate of the magnetic field of the inner magnetic control device and high requirement for the magnetic field strength of the inner 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 can be devised by those skilled in the art without departing from the spirit and scope of the present application. The present application is defined by the appended claims.

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

[0080] Reference is made to the accompanying drawings of the present application Figures 1 to 14 A flywheel assembly according to a first preferred embodiment of the present application will be disclosed and described in the following description, wherein the flywheel assembly comprises an inner magnetic control device 10 and a flywheel 20, the flywheel 20 is configured to be capable of generating rotation relative to the inner magnetic control device 10.

[0081] Specifically, the inner magnetic control device 10 comprises a housing 11, at least one magnetic conductor 12 movably arranged in the housing 11, and at least one magnetic element 22 arranged in the magnetic conductor 12. The flywheel 20 comprises a flywheel body 21 and at least one conductor 13. The flywheel body 21 further comprises a disc 211 and a rim 212 integrally extending from the edge of the disc 211 to the side of the disc 211 to form a flywheel space 213 between the disc 211 and the rim 212, and at least one airflow passage 214 arranged in the disc 211 and communicating the flywheel space 213 with the outside. The conductor 13 is arranged on the inner wall of the rim 212. The inner magnetic control device 10 is arranged in the flywheel space 213 of the flywheel body 21 with the magnetic element 22 located between the magnetic conductor 12 and the conductor 13.

[0082] It can be understood that, after the inner magnetic control device 10 is arranged in the flywheel space 213 of the flywheel body 21, there is a gap between the inner magnetic control device 10 and the flywheel 20, so that friction between the inner magnetic control device 10 and the flywheel 20 is avoided when the flywheel 20 is driven to rotate relative to the inner magnetic control device 10.

[0083] When the flywheel 20 is driven to rotate relative to the inner magnetic control device 10, the conductor 13 of the flywheel 20 cuts the magnetic induction lines of the magnetic element 22 of the inner magnetic control device 10 to allow the flywheel 20 to obtain load, and the conductor 13 generates heat at this time. Since the conductor 13 is located in the flywheel space 213 of the flywheel body 21, the heat generated by the conductor 13 is preferentially radiated to the flywheel space 213 of the flywheel body 21. The flywheel 20 is arranged with the airflow passage 214 in the disc 211 of the flywheel body 21, so that when the flywheel 20 is driven to rotate relative to the inner magnetic control device 10, the airflow passage 214 of the flywheel body 21 allows external gas to flow through the gap between the inner magnetic control device 10 and the flywheel 20 to take away the heat radiated by the conductor 13 to the flywheel space 213 of the flywheel body 21, thereby reducing the working temperature of the inner magnetic control device 10.

[0084] Further, with reference to the accompanying drawings Figure 1 , Figures 3 to 9, the wheel disc 211 of the flywheel body 21 further comprises an assembling disc 2111, a connecting disc 2112 and at least two extension arms 2113, the extension arms 2113 are spaced from each other, and opposite ends of each of the extension arms 2113 extend to and are connected to the assembling disc 2111 and the connecting disc 2112 respectively, so as to form the airflow channel 214 of the flywheel body 21 between adjacent extension arms 2113, wherein the wheel ring 212 integrally extends from the connecting disc 2112 to the side of the wheel disc 211.

[0085] Preferably, the extension direction of at least one of the outer surface 21131 of one of the extension arms 2113 of the wheel disc 211 of the flywheel body 21 and the inner surface 21132 of the adjacent extension arm 2113 is non-perpendicular to the central axis 1000 of the flywheel assembly, so that when the flywheel 20 is driven to rotate relative to the inner magnetic control device 10, the extension arm 2113 of the wheel disc 211 can guide the external gas to flow through the gap between the inner magnetic control device 10 and the flywheel 20, so as to improve the heat dissipation efficiency.

[0086] More preferably, the extension direction of the outer surface 21131 of one of the extension arms 2113 of the wheel disc 211 of the flywheel body 21 and the inner surface 21132 of the adjacent extension arm 2113 are both non-perpendicular to the central axis 1000 of the flywheel assembly, so that when the flywheel 20 is driven to rotate relative to the inner magnetic control device 10 in one direction, referring to the accompanying drawings Figure 5 , the extension arm 2113 of the wheel disc 211 can guide the external gas to flow from the airflow channel 214 of the flywheel body 21 to the gap between the inner magnetic control device 10 and the flywheel 20, and from the opening of the flywheel space 213 of the flywheel body 21 to the gap between the inner magnetic control device 10 and the flywheel 20, and accordingly, when the flywheel 20 is driven to rotate relative to the inner magnetic control device 10 in the opposite direction, referring to the accompanying drawings Figure 6 , the extension arm 2113 of the wheel disc 211 can guide the external gas to flow from the opening of the flywheel space 213 of the flywheel body 21 to the gap between the inner magnetic control device 10 and the flywheel 20, and from the airflow channel 214 of the flywheel body 21 to the gap between the inner magnetic control device 10 and the flywheel 20.

[0087] In other words, the flywheel body 21 is designed in such a way that the extension direction of the outer surface 21131 of one of the extension arms 2113 of the wheel disc 211 and the inner surface 21132 of the adjacent extension arm 2113 are both non-perpendicular to the central axis 1000 of the flywheel assembly, so that no matter which direction (clockwise or counterclockwise) the flywheel 20 rotates, the external gas can be guided by the extension arms 2113 of the wheel disc 211 of the flywheel body 21 to flow through the gap formed between the inner magnetic control device 10 and the flywheel 20, so as to improve the heat dissipation efficiency.

[0088] In addition, the flywheel body 21 is designed in such a way that the extension direction of the outer surface 21131 of one of the extension arms 2113 of the wheel disc 211 and the inner surface 21132 of the adjacent extension arm 2113 are both non-perpendicular to the central axis 1000 of the flywheel assembly, so that the speed of the external gas flowing through the gap formed between the inner magnetic control device 10 and the flywheel 20 is positively correlated with the rotation speed of the flywheel 20, that is, the faster the rotation speed of the flywheel 20, the faster the speed of the external gas flowing through the gap between the inner magnetic control device 10 and the flywheel 20, and the flywheel assembly can provide higher heat dissipation efficiency. In other words, the heat dissipation capacity of the flywheel assembly of the present application is adaptive, which increases with the increase of the rotation speed of the flywheel 20, and the flywheel assembly does not need to be powered during the process of achieving heat dissipation, which is conducive to simplifying the structure of the flywheel assembly and improving the reliability of the flywheel assembly.

[0089] Preferably, in the attached Figures 1 to 14 In this specific example of the flywheel assembly of the present application, the wheel disc 211 of the flywheel body 21 is designed in such a way that the extension arms 2113 are inclined to extend, so that the outer surface 21131 of one of the extension arms 2113 and the inner surface 21132 of the adjacent extension arm 2113 are both non-perpendicular to the central axis 1000 of the flywheel assembly.

[0090] It is worth mentioning that the inner magnetic control device 10 is arranged in the flywheel space 213 of the flywheel body 21 and the flywheel 20 is constructed in such a way that it can rotate relative to the inner magnetic control device 10, which is not limited in the flywheel assembly of the present application. Specifically, in this specific example of the flywheel assembly of the present application, referring to the attached Figures 1 to 6, the flywheel assembly further comprises a mounting shaft 30 and a flange 40 fixedly mounted on the mounting shaft 30, wherein the housing 11 of the inner magnetic control device 10 has a housing through hole 1101 penetrating through opposite sides of the housing 11, wherein the flywheel body 21 of the flywheel 20 has a flywheel through hole 2101 penetrating through opposite sides of the assembling disc 2111, wherein the inner magnetic control device 10 is mounted in the flywheel space 213 of the flywheel body 21, the housing through hole 1101 of the housing 11 and the flywheel through hole 2101 of the flywheel body 21 correspond to each other, wherein after the mounting shaft 30 sequentially penetrates through the housing through hole 1101 of the housing 11 and the flywheel through hole 2101 of the flywheel body 21, the flange 40 is locked on the housing 11, so that the inner magnetic control device 10 is arranged in the flywheel space 213 of the flywheel body 21 and the flywheel 20 is configured to be able to generate rotation relative to the inner magnetic control device 10.

[0091] Turning to the drawings Figures 10 to 14 , the magnetically permeable body 12 of the inner magnetic control device 10 is swingably arranged in the housing 11, and the magnetically permeable body 12 can change the distance between the magnetic element 22 and the conductor 13 when swinging. Specifically, when the magnetically permeable body 12 swings outward to make the magnetic element 22 close to the conductor 13, the flywheel 20 cuts more magnetic induction lines of the magnetic element 22 when driven to rotate relative to the inner magnetic control device 10, at which time the flywheel 20 can obtain a larger load, and correspondingly, when the magnetically permeable body 12 swings inward to make the magnetic element 22 away from the conductor 13, the flywheel 20 cuts less magnetic induction lines of the magnetic element 22 when driven to rotate relative to the inner magnetic control device 10, at which time the flywheel 20 can obtain a smaller load.

[0092] Specifically, the inner magnetic control device 10 comprises a driving unit 14 arranged in the housing 11, wherein the magnetically permeable body 12 has a pivot end 121 and a driven end 122 corresponding to the pivot end 121, the pivot end 121 of the magnetically permeable body 12 is rotatably mounted on the housing 11, and the driven end 122 of the magnetically permeable body 12 is drivably connected to the driving unit 14, wherein the driving unit 14 is configured to be able to apply force to the driven end 122 of the magnetically permeable body 12 to allow the magnetically permeable body 12 to rotate relative to the housing 11 about the pivot end 121, thereby realizing the swinging of the magnetically permeable body 12.

[0093] Preferably, the number of the magnetic conductors 12 of the inner magnetic control device 10 is more than two, each of which is provided with at least one magnetic element 22, and the two or more magnetic conductors 12 are arranged in central symmetry with the center of symmetry on the central shaft 1000 of the flywheel assembly. For example, in the specific example of the flywheel assembly shown in the accompanying drawings, 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 center of symmetry on the central shaft 1000 of the flywheel assembly. Figures 1 to 14 In this specific example of the flywheel assembly shown in the accompanying drawings, 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 center of symmetry on the central shaft 1000 of the flywheel assembly. Alternatively, in other examples of the flywheel assembly of the present application, the two magnetic conductors 12 of the inner magnetic control device 10 are arranged in axial symmetry with the symmetry axis intersecting the central shaft 1000 of the flywheel assembly.

[0094] Continuing to refer to the accompanying drawings, Figure 12 and Figure 14 , 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, the driving ring 142 is rotatably mounted to the housing 11 and is drivably connected to the driving motor 141, and each of the connecting arms 143 has one end portion rotatably mounted to each of the opposite sides of the driving ring 142 and the other end portion 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 shaft 1000 of the flywheel assembly, the driving ring 142 drives each of the magnetic conductors 12 to swing through each of the connecting arms 143, thereby changing the distance between the magnetic elements 22 and the conductor 13.

[0095] Specifically, referring to the accompanying drawings, Figure 14 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, so as to allow each of the magnetic conductors 12 to swing from the maximum swing position to the minimum swing position, respectively, and 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, so as to allow each of the magnetic conductors 12 to swing from the minimum swing position to the maximum swing position, respectively.

[0096] It can be understood that when each of the magnetic conductors 12 is in the maximum swing position, the distance between the magnetic element 22 and the conductor 13 is the shortest, at this time, the load obtained by the flywheel 20 when being driven to rotate relative to the inner magnetic control device 10 is the largest, correspondingly, when each of the magnetic conductors 12 is in the minimum swing position, the distance between the magnetic element 22 and the conductor 13 is the longest, at this time, the load obtained by the flywheel 20 when being driven to rotate relative to the inner magnetic control device 10 is the smallest. Therefore, when each of the magnetic conductors 12 swings from the maximum swing position to the minimum swing position respectively, the load obtained by the flywheel 20 when being driven to rotate relative to the inner magnetic control device 10 gradually decreases, correspondingly, when each of the magnetic conductors 12 swings from the minimum swing position to the maximum swing position respectively, the load obtained by the flywheel 20 when being driven to rotate relative to the inner magnetic control device 10 gradually increases.

[0097] With reference to the accompanying drawings Figures 10 to 14 The shell 11 further comprises a disc-shaped first shell 111 and a disc-shaped second shell 112, and has a shell space 1102, a circumferential opening 1103, and two communication channels 1104. The first shell 111 has a first ring body 1111, and the second shell 112 has a second ring body 1121, wherein 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 as to form the shell space 1102 at the inner side of the first ring body 1111 and the second ring body 1121, form the circumferential opening 1103 at the outer side of the first ring body 1111 and the second ring body 1121, and form the communication channels 1104 between the first ring body 1111 and the second ring body 1121, which communicate the shell space 1102 and the circumferential opening 1103.

[0098] 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 driving motor 141 and the driving ring 142 of the driving 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 rotatably mount one end portion of each of the link arms 143 to each of the opposite sides of the driving ring 142, and to rotatably mount the other end portion of each of the link arms 143 to the driven end 122 of each of the magnet conductors 12, respectively.

[0099] 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, to fixedly mount the first housing 111 and the second housing 112, and to avoid the edges of the first housing 111 and 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.

[0100] Now turning to the drawings Figure 12 and Figure 14The 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 shaft 1000 of the flywheel assembly when being driven by the driving motor 141 to drive the magnet conductor 12 to swing inwardly or outwardly.

[0101] Further, the driving unit 14 comprises a transmission gear set 144, which is used to transmit the power outputted by the output shaft 1411 of the driving motor 141 to the driving ring 142, so as to drive the driving ring 142 to rotate around the central shaft 1000 of the flywheel assembly relative to the housing 11 to drive the magnet conductor 12 to swing inwardly or outwardly.

[0102] Specifically, referring to the accompanying drawings, Figure 12 and Figure 14 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 rotating 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 shaft 1000 of the flywheel assembly relative to the housing 11 to drive the magnet conductor 12 to swing inwardly or outwardly.

[0103] It is worth mentioning that the number of the gears 1441 in the transmission gear set 144 is not limited in the flywheel assembly of the present application. For example, in the specific example of the flywheel assembly of the present application shown in the accompanying drawings, Figures 1 to 14 the number of the gears 1441 of the transmission gear set 144 is three.

[0104] Continuing to refer to the accompanying drawings, Figure 12 and Figure 14The 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 the driving ring 142 from tilting when the driving ring 142 is driven, so as to ensure that the driving ring 142 stably and reliably rotates around the central shaft 1000 of the flywheel assembly relative to the housing 11.

[0105] With reference to the accompanying drawings Figure 12 and Figure 14 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 on the first housing 111, and the auxiliary gear 145 is mounted on the rotating shaft end 1522 of the rotary potentiometer 152. When the driving motor 141 drives each of the magnetic conductors 12 to swing inwards or outwards through each of the connecting arms 143 by driving the driving ring 142 to rotate, 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 value of the rotary potentiometer 152. It can be understood that the resistance value of the rotary potentiometer 152 is related to the rotating position of the driving ring 142, and the rotating position of the driving ring 142 determines the swinging 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 swinging 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 value of the rotary potentiometer 152.

[0106] Preferably, the circuit board 151 of the potential control unit 15 is mounted on 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.

[0107] With reference to the accompanying drawings Figure 12 and Figure 14The 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, and 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.

[0108] Attached Figures 15 to 20 A flywheel assembly according to a second preferred embodiment of the present application, the flywheel assembly comprises an inner magnetic control device 10A and a flywheel 20A, the flywheel 20A is configured to generate rotation relative to the inner magnetic control device 10A.

[0109] Specifically, the inner magnetic control device 10A comprises 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, the conductor 13A is arranged in the housing 11A, and the conductor 13A is located outside the magnetic conductor 12A. The flywheel 20A comprises a flywheel body 21A and at least one magnetic element 22A, the flywheel body 21A comprises a disc 211A and a rim 212A, and has a flywheel space 213A and at least one airflow passage 214A, the rim 212A integrally extends from the edge of the disc 211A to the side of the disc 211A to form the flywheel space 213A between the disc 211A and the rim 212A, the airflow passage 214A is arranged in the disc 211A and communicates the flywheel space 213A with the outside, and the magnetic element 22A is arranged on the inner wall of the rim 212A. The inner magnetic control device 10A is arranged in the flywheel space 213A of the flywheel body 21A with the conductor 13A located between the magnetic conductor 12A and the magnetic element 22A.

[0110] It can be understood that after the inner magnetic control device 10A is arranged in the flywheel space 213A of the flywheel body 21A, there is a gap between the inner magnetic control device 10A and the flywheel 20A, so as to avoid friction between the inner magnetic control device 10A and the flywheel 20A when the flywheel 20A is driven to generate rotation relative to the inner magnetic control device 10A.

[0111] When the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, the conductor 13A cuts the magnetic flux of the magnetic field formed between the magnetic element 22A and the magnetic conductor 12A to allow the flywheel 20A to obtain load, at this time, the conductor 13A generates heat. Since the conductor 13A is arranged in the inner magnetic control device 10A and located in the flywheel space 213A of the flywheel body 21A, the heat generated by the conductor 13A causes the working temperature of the inner magnetic control device 10A to rise. The flywheel 20A is provided with the airflow passage 214A in the flywheel body 21A, when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, the airflow passage 214A of the flywheel body 21A allows external gas to flow through the gap between the inner magnetic control device 10A and the flywheel 20A to take away the heat generated by the conductor 13A, thereby reducing the working temperature of the inner magnetic control device 10A.

[0112] Further, with reference to the accompanying drawings Figures 15 to 17 Further, the flywheel body 21A further comprises an assembling disc 2111A, a connecting disc 2112A and at least two extension arms 2113A, the extension arms 2113A are arranged at intervals and the opposite ends of each extension arm 2113A are respectively extended to and connected to the assembling disc 2111A and the connecting disc 2112A to form the airflow passage 214A of the flywheel body 21A between adjacent extension arms 2113A, wherein the wheel ring 212A is integrally extended from the connecting disc 2112A to the side of the flywheel body 21A.

[0113] Preferably, the extension direction of at least one of the outer surface 21131A of one extension arm 2113A of the flywheel body 21A and the inner surface 21132A of the adjacent extension arm 2113A and the central axis 1000A of the flywheel assembly are not perpendicular, so that when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, the extension arm 2113A of the flywheel body 21A can guide external gas to flow through the gap between the inner magnetic control device 10A and the flywheel 20A to improve heat dissipation efficiency.

[0114] More preferably, the extending direction of the outer surface 21131A of one of the extending arms 2113A of the wheel disc 211A and the inner surface 21132A of the adjacent extending arm 2113A of the flywheel body 21A is non-perpendicular to the central axis 1000A of the flywheel assembly, such that when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A in one direction, the extending arms 2113A of the wheel disc 211A can guide the external gas to flow from the airflow passage 214A of the flywheel body 21A to the gap between the inner magnetic control device 10A and the flywheel 20A and from the opening of the flywheel space 213A of the flywheel body 21A to the gap between the inner magnetic control device 10A and the flywheel 20A, and correspondingly, when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A in the opposite direction, the extending arms 2113A of the wheel disc 211A can guide the external gas to flow from the opening of the flywheel space 213A of the flywheel body 21A to the gap between the inner magnetic control device 10A and the flywheel 20A and from the airflow passage 214A of the flywheel body 21A to the gap between the inner magnetic control device 10A and the flywheel 20A.

[0115] In other words, the flywheel body 21A allows the extending direction of the outer surface 21131A of one of the extending arms 2113A of the wheel disc 211A and the inner surface 21132A of the adjacent extending arm 2113A to be non-perpendicular to the central axis 1000A of the flywheel assembly, such that no matter which direction (clockwise or counterclockwise) the flywheel 20A rotates, the external gas can be guided by the extending arms 2113A of the wheel disc 211A of the flywheel body 21A to flow through the gap between the inner magnetic control device 10A and the flywheel 20A, to improve the heat dissipation efficiency.

[0116] And, the flywheel body 21A is configured in such a way that the extension direction of the outer surface 21131A of one of the extension arms 2113A and the inner surface 21132A of the adjacent extension arm 2113A are both non-perpendicular to the central axis 1000A of the flywheel assembly, so that the speed of the external gas flowing through the gap formed between the inner magnetic control device 10A and the flywheel 20A is positively correlated with the rotation speed of the flywheel 20A, i.e., the faster the rotation speed of the flywheel 20A, the faster the speed of the external gas flowing through the gap between the inner magnetic control device 10A and the flywheel 20A, and the higher the heat dissipation efficiency provided by the flywheel assembly. In other words, the heat dissipation capacity of the flywheel assembly of the present application is adaptive, which is improved with the increase of the rotation speed of the flywheel 20A, and the flywheel assembly does not need to be powered during the process of heat dissipation, which is conducive to simplifying the structure of the flywheel assembly and improving the reliability of the flywheel assembly.

[0117] Preferably, in the attached Figures 15 to 20 In this specific example of the flywheel assembly of the present application, the flywheel body 21A is configured in such a way that the extension arms 2113A are inclined to extend, so that the outer surface 21131A of one of the extension arms 2113A and the inner surface 21132A of the adjacent extension arm 2113A are both non-perpendicular to the central axis 1000A of the flywheel assembly.

[0118] It is worth mentioning that the inner magnetic control device 10A is arranged in the flywheel space 213A of the flywheel body 21A and the flywheel 20A is configured to be able to generate rotation relative to the inner magnetic control device 10A, which is not limited in the flywheel assembly of the present application. Specifically, in this specific example of the flywheel assembly of the present application, referring to the attached Figure 15 and Figure 16, the flywheel assembly further comprises a mounting shaft 30A and a flange 40A fixedly mounted on the mounting shaft 30A, wherein the housing 11A of the inner magnetic control device 10A has a housing through hole 1101A penetrating through opposite sides of the housing 11A, wherein the flywheel body 21A of the flywheel 20A has a flywheel through hole 2101A penetrating through opposite sides of the assembling disc 2111A, wherein the inner magnetic control device 10A is mounted in the flywheel space 213A of the flywheel body 21A, the housing through hole 1101A of the housing 11A and the flywheel through hole 2101A of the flywheel body 21A correspond to each other, wherein after the mounting shaft 30A sequentially penetrates through the housing through hole 1101A of the housing 11A and the flywheel through hole 2101A of the flywheel body 21A at one end of the mounting shaft 30A, the flange 40A is locked on the housing 11A, so that the inner magnetic control device 10A is arranged in the flywheel space 213A of the flywheel body 21A and the flywheel 20A is configured to be able to rotate relative to the inner magnetic control device 10A.

[0119] As described above, and with continued reference to the drawings Figures 15 to 17 , the wheel ring 212A of the flywheel body 21A integrally extends from the edge of the wheel disc 211A to the side of the wheel disc 211A. For example, in some embodiments, the wheel disc 211A and the wheel ring 212A of the flywheel body 21A are cast pieces that can be integrally formed by a casting process from a metal material, so that the flywheel body 21A has a heavy mass as a counterweight part of the flywheel 20A.

[0120] In some embodiments of the flywheel assembly of the present application, the number of the magnetic elements 22A can be one, which is a complete annular. In other embodiments of the flywheel assembly of the present application, the number of the magnetic elements 22A is two, two of the magnetic elements 22A respectively extend in a curved manner, wherein after two of the magnetic elements 22A are respectively arranged in the wheel ring 212A of the flywheel body 21A, two of the magnetic elements 22A can form a complete magnetic ring. In still other embodiments of the flywheel assembly of the present application, the number of the magnetic elements 22A can be more than three, these magnetic elements 22A respectively extend in a curved manner or are cuboids, wherein after these magnetic elements 22A are respectively arranged shoulder by shoulder in the wheel ring 212A of the flywheel body 21A, these magnetic elements 22A can form a complete magnetic ring.

[0121] It is worth mentioning that the manner of arranging the magnetic element 22A on the wheel ring 212A of the flywheel body 21A is not limited in the flywheel assembly of the present application, as long as the magnetic element 22A is reliably fixed on the wheel ring 212A of the flywheel body 21A to allow the magnetic element 22A to rotate synchronously with the flywheel body 21A. For example, in some embodiments of the flywheel assembly of the present application, the magnetic element 22A can be integrally pressed on the wheel ring 212A of the flywheel body 21A, which is conducive to simplifying the assembly process of the flywheel 20A and improving the assembly effect of the flywheel 20A.

[0122] Moreover, on the one hand, even if no glue is arranged between the magnetic element 22A and the wheel ring 212A of the flywheel body 21A, as long as the sizes of the magnetic element 22A and the wheel ring 212A of the flywheel body 21A are properly matched, for example, the outer diameter size of the magnetic element 22A is consistent with the inner diameter size of the wheel ring 212A of the flywheel body 21A, when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A and is subjected to centrifugal force, the magnetic element 22A can be tightly attached to the wheel ring 212A of the flywheel body 21A to avoid the magnetic element 22A from falling off the wheel ring 212A of the flywheel body 21A, and the faster the rotation speed of the flywheel 20A, the more tightly the magnetic element 22A can be attached to the wheel ring 212A of the flywheel body 21A, which is conducive to ensuring the reliability of the flywheel assembly. On the other hand, there is no risk of reversing the N-pole and S-pole of the magnetic element 22A during the assembly of the flywheel 20A, which is crucial for ensuring the overall magnetic field strength of the magnetic element 22A.

[0123] After the magnetic element 22A is arranged on the wheel ring 212A of the flywheel body 21A, the weight of the flywheel 20A can be increased. In other words, the magnetic element 22A can be used to provide a magnetic field and also to provide a counterweight.

[0124] In addition, the flywheel assembly is capable of quickly dissipating the heat of the magnetic element 22A to reduce the temperature of the magnetic element 22A itself and the surrounding environment when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, thereby avoiding the heat to affect the magnetic field strength of the magnetic element 22A and prolonging the service life of the magnetic element 22A. Meanwhile, the airflow passage 214A of the flywheel body 21A allows the external gas to flow through the gap formed between the inner magnetic control device 10A and the flywheel 20A, so that the magnetic element 22A can be quickly cooled to quickly reduce the temperature of the magnetic element 22A itself and the surrounding environment, thereby avoiding the heat to affect the magnetic field strength of the magnetic element 22A and prolonging the service life of the magnetic element 22A

[0125] That is, in the flywheel assembly of the present application, by arranging the magnetic element 22A on the flywheel body 21A, arranging the magnetic conductor 12A and the conductor 13A on the shell 11A and keeping the conductor 13A between the magnetic element 22A and the magnetic conductor 12A, and providing the airflow passage 214A on the flywheel body 21A, 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, second, when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, the conductor 13A cuts the magnetic induction lines in the middle of the magnetic field formed between the magnetic conductor 12A and the magnetic element 22A to load the flywheel 20A, 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 tightly attached to the wheel ring 212A of the flywheel body 21A due to the centrifugal force, thereby avoiding the magnetic element 22A from falling off, 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 the heat to reduce the temperature of the magnetic element 22A itself and the surrounding environment, fifth, when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10A, the external gas is guided to flow through the gap formed between the inner magnetic control device 10A and the flywheel 20A to take away the heat, thereby quickly reducing the temperature of the magnetic element 22A itself and the surrounding environment and reducing the working temperature of the inner magnetic control device 10A, and sixth, the conductor 13A and the magnetic element 22A are always kept in place to ensure that the flywheel assembly can provide good damping effect.

[0126] In addition, the heat dissipation capacity of the flywheel assembly of the present application is self-adaptive, which is increased with the increase of the rotating speed of the flywheel 20A, and the flywheel assembly does not need to be functionalized in the process of achieving heat dissipation, thus facilitating the simplification of the structure of the flywheel assembly and the improvement of the reliability of the flywheel assembly.

[0127] Now turning to the drawings Figure 18 and Figure 20 The inner magnetic control device 10A further comprises a driving unit 14A arranged in 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 on the housing 11A, and the driven end 122A of the magnetic conductor 12A is drivingly 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 positions of the magnetic element 22A and the magnetic conductor 12A, thereby changing the magnetic field strength formed between the magnetic element 22A and the magnetic conductor 12A.

[0128] Preferably, the magnetic conductor 12A extends curvedly between the pivot end 121A and the driven end 122A so that the magnetic conductor 12A is arc-shaped, so that the shape of the outer side of the magnetic conductor 12A is substantially the same as the shape of the periphery of the housing 11A.

[0129] Preferably, the number of the magnetic conductors 12A of the inner magnetic control device 10A is two or more, and the two or more magnetic conductors 12A are arranged in central symmetry, with the center of symmetry located on the central axis 1000A of the flywheel assembly. For example, in the specific example of the flywheel assembly shown in FIG. 1, the number of the magnetic conductors 12A of the inner magnetic control device 10A is two, and the two magnetic conductors 12A are arranged in central symmetry, with the center of symmetry located on the central axis 1000A of the flywheel assembly. Figures 15 to 20 In this specific example of the flywheel assembly shown in FIG. 1, the number of the magnetic conductors 12A of the inner magnetic control device 10A is two, and the two magnetic conductors 12A are arranged in central symmetry, with the center of symmetry located on the central axis 1000A of the flywheel assembly. Alternatively, in other examples of the flywheel assembly of the present application, the two magnetic conductors 12A of the inner magnetic control device 10A are arranged in axial symmetry, with the symmetry axis intersecting the central axis 1000A of the flywheel assembly.

[0130] Continuing to refer to the drawings Figure 18 and Figure 20, the driving unit 14A is capable of simultaneously driving two of the magnet conductors 12A to swing at the same amplitude. Specifically, the driving unit 14A comprises a driving motor 141A, a driving ring 142A and two connecting arms 143A, the driving motor 141A is mounted on the housing 11A, the driving ring 142A is rotatably mounted on the housing 11A and is drivingly connected to the driving motor 141A, wherein one end of each of the connecting arms 143A is rotatably mounted on each of the opposite sides of the driving ring 142A, and the other end of each of the connecting arms 143A is rotatably mounted on the driven end 122A of each of the magnet conductors 12A. When the driving motor 141A drives the driving ring 142A to rotate around the central axis 100 of the flywheel assembly, the driving ring 142A drives each of the magnet conductors 12A to swing through each of the connecting arms 143A, thereby changing the magnetic field strength formed between the magnetic element 22A and the magnet conductor 12A.

[0131] Specifically, with reference to the accompanying drawings Figure 20 When the driving motor 141A drives the driving ring 142A to rotate clockwise, the driving ring 142A drives each of the magnet conductors 12A to swing inward through each of the connecting arms 143A, so as to allow each of the magnet conductors 12A to swing from the maximum swing position to the minimum swing position, respectively. Correspondingly, when the driving motor 141A drives the driving ring 142A to rotate counterclockwise, the driving ring 142A drives each of the magnet conductors 12A to swing outward through each of the connecting arms 143A, so as to allow each of the magnet conductors 12A to swing from the minimum swing position to the maximum swing position, respectively.

[0132] It can be understood that when each of the magnet conductors 12A is at the maximum swing position, the flywheel assembly forms the strongest magnetic field strength between the magnetic element 22A and the magnet conductor 12A, and correspondingly, when each of the magnet conductors 12A is at the minimum swing position, the flywheel assembly forms the weakest magnetic field strength between the magnetic element 22A and the magnet conductor 12A. Therefore, when each of the magnet conductors 12A swings from the maximum swing position to the minimum swing position, respectively, the flywheel assembly gradually weakens the magnetic field strength formed between the magnetic element 22A and the magnet conductor 12A, and correspondingly, when each of the magnet conductors 12A swings from the minimum swing position to the maximum swing position, respectively, the flywheel assembly gradually strengthens the magnetic field strength formed between the magnetic element 22A and the magnet conductor 12A.

[0133] Continuing to refer to the accompanying drawings Figures 18 to 20The housing 11A further comprises a first disc-shaped casing 111A and a second disc-shaped casing 112A, and has a casing space 1102A, a peripheral opening 1103A, and two communication passages 1104A. The first casing 111A has a first ring body 1111A, and the second casing 112A has a second ring body 1121A. The first casing 111A and the second casing 112A are installed in a corresponding manner with the first ring body 1111A and the second ring body 1121A, so that the casing 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 casing space 1102A and the peripheral opening 1103A.

[0134] The opposite sides of the pivot end 121A of the magnet conductor 12A are rotatably installed on the edges of the first casing 111A and the second casing 112A, so that the pivot end 121A of the magnet conductor 12A is rotatably installed on the edges of the housing 11A, and the magnet conductor 12A is allowed to swing in the peripheral opening 1103A of the housing 11A. The opposite sides of the conductor 13A extend to and are fixed on the edges of the first casing 111A and the second casing 112A, so that the conductor 13A is arranged in the housing 11A and held by the housing 11A between the magnet conductor 12A and the magnetic element 22A. Preferably, the conductor 13A is annular and surrounds the outside of the magnet conductor 12A. The driving motor 141A and the driving ring 142A of the driving unit 14A are located in the casing space 1102A of the housing 11A, and each of the communication passages 1104A of the housing 11A extends from the casing space 1102A to the peripheral opening 1103A, so that one end of each of the communication passages 1104A is rotatably installed on each of the opposite sides of the driving ring 142A, and the other end of each of the communication passages 1104A is rotatably installed on the driven end 122A of each of the magnet conductors 12A.

[0135] Further, the first housing 111A has a plurality of first mounting posts 1112A disposed on the outer side of the first ring body 1111A, and the second housing 112A has a plurality of second mounting posts 1122A disposed on the outer side of 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 with each other to fixedly mount the first housing 111A and the second housing 112A, and to avoid the edges of the first housing 111A and the edges of the second housing 112A from being deformed. Preferably, screws are allowed to be mounted on 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 magnet conductor 12A to swing to the minimum swing position.

[0136] Now turning to the drawings Figure 18 and Figure 20 The driving motor 141A of the driving unit 14A is fixedly mounted on the first housing 111A of the outer shell 11A. The first housing 111A has a boss 1113A, wherein the driving ring 142A is rotatably sleeved on the boss 1113A of the first housing 111A, so that the driving ring 142A can be rotated around the central shaft 1000A of the flywheel assembly when being driven by the driving motor 141A to drive the magnet conductor 12A to swing inwardly or outwardly.

[0137] 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 shaft 1000A of the flywheel assembly relative to the outer shell 11A to drive the magnet conductor 12A to swing inwardly or outwardly.

[0138] In particular, reference is made to the drawings Figure 18 and Figure 20, the drive ring 142A has a first set of ring teeth 1421A, and the transmission gear set 144A is composed of a plurality of meshed gears 1441A, each of which is rotatably mounted to the first housing 111A and the second housing 112A in the housing space 1102A of the housing 11A, one of the gears 1441A is engaged with the output shaft 1411A of the drive motor 141A, and another of the gears 1441A is engaged with the first set of ring teeth 1421A of the drive ring 142A, so that when the drive motor 141A outputs power in the manner of rotating the output shaft 1411A of the drive motor 141A, power can be transmitted to the drive ring 142A through the transmission gear set 144A to drive the drive ring 142A to rotate around the central shaft 1000A of the flywheel assembly relative to the housing 11A to drive the magnetically permeable body 12A to swing inwardly or outwardly.

[0139] It is worth mentioning that the number of gears 1441A in the transmission gear set 144A is not limited in the flywheel assembly of the present application. For example, in the specific example of the flywheel assembly of the present application shown in FIG. 1, the number of gears 1441A in the transmission gear set 144A is three. Figures 15 to 20

[0140] Continuing to refer to FIG. 1, the drive unit 14A further includes an auxiliary gear 145A rotatably mounted to the housing space 1102A of the housing 11A, and the drive ring 142A has a second set of ring teeth 1422A, the second set of ring teeth 1422A of the drive ring 142A and the auxiliary gear 145A are engaged to avoid the drive ring 142A from tilting when the drive ring 142A is driven, thereby ensuring that the drive ring 142A stably and reliably rotates around the central shaft 1000A of the flywheel assembly relative to the housing 11A. Figure 18 Figure 20 Continuing to refer to FIG. 1, the drive unit 14A further includes an auxiliary gear 145A rotatably mounted to the housing space 1102A of the housing 11A, and the drive ring 142A has a second set of ring teeth 1422A, the second set of ring teeth 1422A of the drive ring 142A and the auxiliary gear 145A are engaged to avoid the drive ring 142A from tilting when the drive ring 142A is driven, thereby ensuring that the drive ring 142A stably and reliably rotates around the central shaft 1000A of the flywheel assembly relative to the housing 11A.

[0141] Continuing to refer to FIG. 1, the drive unit 14A further includes an auxiliary gear 145A rotatably mounted to the housing space 1102A of the housing 11A, and the drive ring 142A has a second set of ring teeth 1422A, the second set of ring teeth 1422A of the drive ring 142A and the auxiliary gear 145A are engaged to avoid the drive ring 142A from tilting when the drive ring 142A is driven, thereby ensuring that the drive ring 142A stably and reliably rotates around the central shaft 1000A of the flywheel assembly relative to the housing 11A. Figure 18 Figure 20 ​​​The inner magnetic control device 10A further comprises a potential control unit 15A, the potential control unit 15A comprises a circuit board 151A and a rotary potentiometer 152A connected to the circuit board 151A, the driving motor 141A is connected to the circuit board 151A, wherein the rotary potentiometer 152A has a mounting end 1521A and a shaft end 1522A corresponding to the mounting end 1521A, the mounting end 1521A of the rotary potentiometer 152A is mounted to the first shell 111A, and the auxiliary gear 145A is mounted to the 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 the driving of the driving ring 142A and each of the connecting arms 143A, the driving ring 142A drives the auxiliary gear 145A to rotate, and at the same time, the auxiliary gear 145A drives the 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 being driven to rotate. In other words, the swinging position of the magnetic conductor 12A and the load of the flywheel 20A when being driven to rotate can be detected by detecting the resistance of the rotary potentiometer 152A.

[0142] Preferably, the circuit board 151A of the potential control unit 15A is mounted to the first shell 111A of the outer shell 11A. Preferably, the circuit board 151A is retained in the shell space 1102A of the outer shell 11A to hide the circuit board 151A.

[0143] With continued reference to the drawings Figures 18 to 20 The inner magnetic control device 10A further comprises two assemblies 16A, one end of the connecting arm 143A of the driving unit 14A is rotatably mounted to the assembly 16A, and the assembly 16A is mounted to the driven end 122A of the magnetic conductor 12A, so that one end of the connecting arm 143A is rotatably mounted to the driven end 122A of the magnetic conductor 12A.

[0144] Preferably, the conductor 13A has two escape spaces 131A extending from the inner wall toward the outer wall of the conductor 13A. The positions of the escape spaces 131A of the conductor 13A correspond to the assembly 16A. This allows the conductor 13A to avoid the assembly 16A when the magnetic body 12A swings outward, thereby preventing the assembly 16A from affecting the magnetic body 12A's swing toward its maximum swing position. Preferably, the escape spaces 131A of the conductor 13A extend from the inner wall to the outer wall of the conductor 13A.

[0145] Now go to the attached Figures 18 to 20 The internal magnetic control device 10A further includes at least one power generation unit 17A, each of the power generation units 17A includes a coil frame 171A and at least one coil 172A arranged on the coil frame 171A, the coil frame 171A is arranged on the housing 11A, and the coil 172A is arranged adjacent to the magnetic element 22A, so that when the flywheel 20A is driven to rotate relative to the internal magnetic control device 10A, the coil 172A can generate electrical energy based on the principle of electromagnetic induction.

[0146] Preferably, the coil 172A of the power generation unit 17A is connected to the circuit board 151A of the potential control unit 15A, so that the electric energy generated by the coil 172A can be provided to the driving motor 141A through the circuit board 151A.

[0147] Preferably, the number of the power generation units 17A is two, and the coil 172A of each power generation unit 17A is connected to the circuit board 151A of the potential control unit 15A, so that the drive motor 141A can obtain sufficient electrical energy to meet working requirements.

[0148] Preferably, the two power generation units 17A are arranged symmetrically. Figures 15 to 20 In the illustrated example of the flywheel assembly, each power generation unit 17A is positioned between the pivot end 121A of one magnetizer 12A and the driven end 122A of an adjacent magnetizer 12A, thereby symmetrically arranging the two power generation units 17A. Furthermore, positioning the power generation units 17A between the pivot end 121A of one magnetizer 12A and the driven end 122A of an adjacent magnetizer 12A does not affect the magnetic field strength of the flywheel assembly.

[0149] Continue to refer to the attached Figures 18 to 20The coil holder 171A further comprises a holder body 1711A and at least one winding arm 1712A integrally extended from the holder body 1711A, the coil 172A is wound on the winding arm 1712A, wherein the holder body 1711A is mounted on the first casing 111A of the housing 11A, and the coil holder 171A is retained in the peripheral opening 1103A of the housing 11A, so that the coil holder 171A makes the coil 172A retained in the position adjacent to the magnetic element 22A.

[0150] Preferably, the coil holder 171A comprises three winding arms 1712A integrally extended from the holder body 1711A, wherein the number of the coils 172A is three, and each winding arm 1712A of the coil holder 171A is wound with one coil 172A, so that the driving motor 141A can obtain sufficient electric energy to meet the working requirements.

[0151] Now turning to the drawings Figure 18 and Figure 19 The conductor 13A has at least one through hole 132A extending from the inner wall to the outer wall of the conductor 13A to penetrate the opposite sides of the conductor 13A, wherein the power generation unit 17A extends from the inner side to the outer side of the conductor 13A through the through hole 132A of the conductor 13A, so that: on the one hand, the conductor 13A can avoid the power generation unit 17A to avoid affecting the size of the power generation unit 17A, that is, the power generation unit 17A can be designed to have a larger size to improve the power generation capacity of the power generation unit 17A, on the other hand, the conductor 13A can be implemented as a complete ring, so that the flywheel 20A has sufficient load when being driven to rotate relative to the inner magnetic control device 10A.

[0152] Attached Figure 21 A variant of the flywheel assembly of the present application is shown, which is different from the flywheel assembly shown in the attached Figures 15 to 20 The flywheel assembly shown in the attached Figure 21 In this specific example of the flywheel assembly shown in the attached

[0153] Preferably, in the attached Figure 21In this specific example of the flywheel assembly of the present application, the linkage arm 143A is flexible, for example, the linkage arm 143A can be a pull cord. When the drive motor 141A drives the drive ring 142A to rotate clockwise through the transmission gear set 144A, the drive ring 142A pulls the magnet conductor 12A to swing inwards through the linkage arm 143A, at this time, the elastic element 146A is extruded by the magnet conductor 12A and the housing 11A to generate elastic deformation to accumulate elastic potential energy. Correspondingly, when the drive motor 141A drives the drive ring 142A to rotate anticlockwise through the transmission gear set 144A, the elastic element 146A pushes the magnet conductor 12A to swing outwards in the process of returning to the initial state.

[0154] Attached Figures 22 to 25 Another inner magnetic control device 10B of the flywheel assembly according to the second preferred example of the present application is shown, wherein the flywheel 20A is configured to be able to generate rotation relative to the inner magnetic control device 10B.

[0155] Specifically, the inner magnetic control device 10B includes a housing 11B, at least one magnet conductor 12B and at least one conductor 13B, the magnet conductor 12B is movably arranged in the housing 11B, the conductor 13B is arranged in the magnet conductor 12B, and the conductor 13B is located outside the magnet conductor 12B. The inner magnetic control device 10B is arranged in the flywheel space 213A of the flywheel body 21A, so that the conductor 13B is maintained between the magnet conductor 12B and the magnetic element 22A. When the flywheel 20A is driven to generate rotation relative to the inner magnetic control device 10B, the conductor 13B cuts the magnetic lines of the magnetic field formed between the magnetic element 22A and the magnet conductor 12B to allow the flywheel 20A to obtain load. By changing the way of the magnet conductor 12B, the magnetic field strength formed between the magnetic element 22A and the magnet conductor 12B is changed to adjust the load that the flywheel 20A can obtain.

[0156] In the flywheel assembly of the present application, by means of setting the magnetic element 22A on the flywheel body 21A, setting the magnetic conductor 12B on the housing 11B, setting the conductor 13B on the magnetic conductor 12B and the flywheel body 21A providing the airflow channel 214A, in the first aspect, the flywheel body 21A and the magnetic element 22A can jointly serve as the counterweight part of the flywheel 20A, so as to reduce the cost of the flywheel assembly; in the second aspect, when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10B, the conductor 13B cuts the magnetic induction lines in the middle of the magnetic field formed between the magnetic conductor 12B and the magnetic element 22A, so that the flywheel 20A obtains load, so as to efficiently utilize the magnetic field and reduce the requirement for the magnetic field strength; in the third aspect, when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10B, the magnetic element 22A can be tightly attached to the wheel ring 212A of the flywheel body 21A under the action of centrifugal force, so as to avoid the magnetic element 22A from falling off; in the fourth aspect, after the heat generated by the conductor 13B 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, so as to reduce the temperature of the magnetic element 22A itself and the surrounding environment; in the fifth aspect, when the flywheel 20A is driven to rotate relative to the inner magnetic control device 10B, external gas is guided to flow through the gap formed between the inner magnetic control device 10B and the flywheel 20A, so as to take away heat, thereby quickly reducing the temperature of the magnetic element 22A itself and the surrounding environment and reducing the working temperature of the inner magnetic control device 10B.

[0157] In addition, the heat dissipation capacity of the flywheel assembly of the present application is adaptive, which is improved with the increase of the rotating speed of the flywheel 20A, and the flywheel assembly does not need to be functional in the process of achieving heat dissipation, so as to simplify the structure of the flywheel assembly and improve the reliability of the flywheel assembly.

[0158] It can be understood that, the same as the flywheel assembly shown in the drawings, Figures 15 to 20 the same as the flywheel assembly shown in the drawings, Figures 22 to 25 In this specific example of the flywheel assembly shown in the drawings, the inner magnetic control device 10B and the flywheel 20A are assembled through the mounting shaft 30A and the flange 40A, so that the flywheel 20A is configured to be able to generate rotation relative to the inner magnetic control device 10B.

[0159] Specifically, the outer shell 11B of the inner magnetic control device 10B has a shell through hole 1101B penetrating through opposite sides of the outer shell 11B, which corresponds to the flywheel through hole 2101A of the flywheel body 21A after the inner magnetic control device 10B is installed in the flywheel space 213A of the flywheel body 21A of the flywheel 20A, wherein the flange 40A fixedly arranged on the mounting shaft 30A is locked to the outer shell 11B after sequentially penetrating through the shell through hole 1101B of the outer shell 11B and the flywheel through hole 2101A of the flywheel body 21A at one end of the mounting shaft 30A, thus assembling the inner magnetic control device 10B to the flywheel 20A and allowing the flywheel 20A to rotate relative to the inner magnetic control device 10B around the mounting shaft 30A.

[0160] The inner magnetic control device 10B further comprises a driving unit 14B arranged in the outer shell 11B. The magnetically permeable body 12B has a pivot end 121B and a driven end 122B corresponding to the pivot end 121B, wherein the pivot end 121B of the magnetically permeable body 12B is rotatably mounted to the outer shell 11B, and the driven end 122B of the magnetically permeable body 12B is drivably connected to the driving unit 14B. The driving unit 14B is arranged to drive the magnetically permeable body 12B to swing relative to the outer shell 11B to change the positions of the magnetic element 22A and the magnetically permeable body 12B, thereby changing the magnetic field strength formed between the magnetic element 22A and the magnetically permeable body 12B. It can be understood that when the driving unit 14B drives the magnetically permeable body 12B to swing relative to the outer shell 11B, the magnetically permeable body 12B drives the conductor 13B to swing synchronously.

[0161] Preferably, the magnetically permeable body 12B is curvedly extended between the pivot end 121B and the driven end 122B to make the magnetically permeable body 12B arc-shaped, so that the shape of the outer side of the magnetically permeable body 12B is substantially the same as the shape of the periphery of the outer shell 11B.

[0162] Preferably, the conductor 13B is arc-shaped, and the curvature of the conductor 13B matches the curvature of the magnetically permeable body 12B to allow the conductor 13B to be arranged on the magnetically permeable body 12B in a manner that the conductor 13B and the magnetically permeable body 12B face and adhere to each other.

[0163] It is worth mentioning that the manner in which the conductor 13B is arranged on the magnet 12B is not limited in the flywheel assembly of the present invention. For example, glue can be used to bond the conductor 13B and the magnet 12B to set the conductor 13B on the magnet 12B, or the conductor 13B and the magnet 12B can be riveted to set the conductor 13B on the magnet 12B.

[0164] Preferably, the number of the magnetic conductors 12B and the conductors 13B of the internal magnetic control device 10B is more than two, one conductor 13B is provided on the outside of each magnetic conductor 12B, and the two or more magnetic conductors 12B are symmetrically arranged. Figures 22 to 25 In the specific example of the flywheel assembly shown, the number of the magnetic conductors 12B and the conductors 13B of the internal magnetic control device 10B is two, and the two magnetic conductors 12B are arranged in a centrally symmetrical manner. Alternatively, in other examples, the two magnetic conductors 12B are arranged in an axisymmetric manner.

[0165] Continue to refer to the attached Figures 22 to 25 The internal magnetic control device 10B further includes at least two flexible conductive elements 18B, each of which has opposite ends connected to two adjacent conductors 13B, so that the conductive elements 18B are conductively connected to the two adjacent conductors 13B. When the magnetic conductor 12B drives the conductors 13B to swing, the conductive elements 18B can deform to ensure that the conductive elements 18B are always conductively connected to the two adjacent conductors 13B. When the flywheel 20A is driven to rotate relative to the internal magnetic control device 10A, each conductor 13B will generate eddy currents due to cutting magnetic flux lines. By connecting the two adjacent conductors 13B through the conductive elements 18B, the eddy currents generated by these conductors 13B can be balanced, thereby helping the flywheel 20A rotate smoothly and reducing vibration. This is crucial for improving user experience and reducing vibration and noise in fitness equipment using the flywheel assembly.

[0166] Now go to the attached Figure 22 and Figure 23, the driving unit 14B is capable of simultaneously driving two of the magnet conductors 12B to swing at the same amplitude. 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 to the housing 11B, wherein the driving ring 142B is rotatably mounted to 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 to each of the opposite sides of the driving ring 142B, and the other end of each of the connecting arms 143B is rotatably mounted to the driven end 122B of each of the magnet conductors 12B. When the driving motor 141B drives the driving ring 142B to rotate, the driving ring 142B drives each of the magnet conductors 12B to swing through each of the connecting arms 143B, thus changing the magnetic field strength formed between the magnetic element 22A and the magnet conductor 12B.

[0167] Specifically, referring to the drawings, Figure 22 and Figure 23 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 inwards through each of the connecting arms 143B, so as to allow each of the magnet conductors 12B to swing from the maximum swing position to the minimum swing position, respectively, at this time, the state of the conductive element 18B is automatically contracted along with the inward swing of the magnet conductor 12B, accordingly, when the driving motor 141B drives the driving ring 142B to rotate counterclockwise, the driving ring 142B drives each of the magnet conductors 12A to swing outwards through each of the connecting arms 143B, so as to allow each of the magnet conductors 12B to swing from the minimum swing position to the maximum swing position, respectively, at this time, the state of the conductive element 18B is automatically expanded along with the outward swing of the magnet conductor 12B.

[0168] It can be understood that when each of the magnet conductors 12B is at the maximum swing position, the magnetic field strength formed between the magnetic element 22A and the magnet conductor 12B by the flywheel assembly is the strongest, accordingly, when each of the magnet conductors 12B is at the minimum swing position, the magnetic field strength formed between the magnetic element 22A and the magnet conductor 12B by the flywheel assembly is the weakest, therefore, when each of the magnet conductors 12B swings from the maximum swing position to the minimum swing position, respectively, the magnetic field strength formed between the magnetic element 22A and the magnet conductor 12B by the flywheel assembly gradually weakens, accordingly, when each of the magnet conductors 12B swings from the minimum swing position to the maximum swing position, respectively, the magnetic field strength formed between the magnetic element 22A and the magnet conductor 12B by the flywheel assembly gradually strengthens.

[0169] With reference to the drawings, the housing 11B further comprises a first disc-shaped housing 111B and a second disc-shaped housing 112B, and has a housing space 1102B, a peripheral opening 1103B, and two communication passages 1104B. The first housing 111B has a first ring body 1111B, and the second housing 112B has a second ring body 1121B. The first housing 111B and the second housing 112B are installed to each other in a manner that the first ring body 1111B and the second ring body 1121B correspond to each other, so that the housing space 1102B is formed inside the first ring body 1111B and the second ring body 1121B, the peripheral opening 1103B is formed outside the first ring body 1111B and the second ring body 1121B, and the communication passage 1104B is formed between the first ring body 1111B and the second ring body 1121B, and the communication passage 1104B communicates the housing space 1102B and the peripheral opening 1103B. Figures 22 to 25 The opposite sides of the pivot end 121B of the magnet conductor 12B are rotatably installed to the edge of the first housing 111B and the edge of the second housing 112B, respectively, so that the pivot end 121B of the magnet conductor 12B is rotatably installed to the edge of the housing 11B, and the magnet conductor 12B is allowed to swing in the peripheral opening 1103B of the housing 11B. The driving motor 141B and the driving ring 142B of the driving unit 14B are located in the housing space 1102B of the housing 11B, respectively, each of the communication passages 1104B of the housing 11B extends from the housing space 1102B to the peripheral opening 1103B, so that one end portion of each of the communication arms 143B is rotatably installed to each of the opposite sides of the driving ring 142B, and the other end portion of each of the communication arms 143B is rotatably installed to the driven end 122B of each of the magnet conductors 12B.

[0170] The opposite sides of the pivot end 121B of the magnet conductor 12B are rotatably installed to the edge of the first housing 111B and the edge of the second housing 112B, respectively, so that the pivot end 121B of the magnet conductor 12B is rotatably installed to the edge of the housing 11B, and the magnet conductor 12B is allowed to swing in the peripheral opening 1103B of the housing 11B. The driving motor 141B and the driving ring 142B of the driving unit 14B are located in the housing space 1102B of the housing 11B, respectively, each of the communication passages 1104B of the housing 11B extends from the housing space 1102B to the peripheral opening 1103B, so that one end portion of each of the communication arms 143B is rotatably installed to each of the opposite sides of the driving ring 142B, and the other end portion of each of the communication arms 143B is rotatably installed to the driven end 122B of each of the magnet conductors 12B.

[0171] 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 by 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.

[0172] With continued reference to the drawings Figures 22 to 25 The driving unit 14B has a driving motor 141B fixedly mounted on the first housing 111B of the housing 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 is driven to rotate by the driving motor 141B to drive the magnet conductor 12B to swing inwardly or outwardly.

[0173] Further, the driving unit 14B includes a transmission gear set 144B for transmitting power output by an output shaft 1411B of the driving motor 141B to the driving ring 142B to drive the driving ring 142B to rotate relative to the housing 11B to drive the magnet conductor 12B to swing inwardly or outwardly.

[0174] In particular, with continued reference to the drawings Figures 22 to 25, the drive ring 142B has a first set of ring teeth 1421B, and the transmission gear set 144B is composed of a plurality of meshed gears 1441B, each of which is rotatably mounted to the first housing 111B and the second housing 112B in the housing space 1102B of the housing 11B, wherein one of the gears 1441B is engaged with the output shaft 1411B of the drive motor 141B, and another of the gears 1441B is engaged with the first set of ring teeth 1421B of the drive ring 142B, so that when the drive motor 141B outputs power in the manner of rotating the output shaft 1411B of the drive motor 141B, power can be transmitted to the drive ring 142B via the transmission gear set 144B to drive the drive ring 142B to rotate relative to the housing 11B to drive the magnet conductor 12B to swing inwardly or outwardly.

[0175] It is worth mentioning that the number of gears 1441B in the transmission gear set 144B is not limited in the flywheel assembly of the present application. For example, in the specific example of the flywheel assembly of the present application shown in FIG. 14B, the number of gears 1441B in the transmission gear set 144B is three. Figures 22 to 25

[0176] Continuing to refer to FIG. 14B, the drive unit 14B further includes an auxiliary gear 145B rotatably mounted in the housing space 1102B of the housing 11B, wherein the drive ring 142B has a second set of ring teeth 1422B, and the second set of ring teeth 1422B of the drive ring 142B is engaged with the auxiliary gear 145B to avoid the drive ring 142B from tilting when the drive ring 142B is driven, thereby ensuring that the drive ring 142B stably and reliably rotates relative to the housing 11B. Figures 22 to 25

[0177] Continuing to refer to FIG. 14B, the drive unit 14B further includes an auxiliary gear 145B rotatably mounted in the housing space 1102B of the housing 11B, wherein the drive ring 142B has a second set of ring teeth 1422B, and the second set of ring teeth 1422B of the drive ring 142B is engaged with the auxiliary gear 145B to avoid the drive ring 142B from tilting when the drive ring 142B is driven, thereby ensuring that the drive ring 142B stably and reliably rotates relative to the housing 11B. Figures 22 to 25 ​​The inner magnetic control device 10B further comprises a potential control unit 15B, which comprises a circuit board 151B and a rotary potentiometer 152B connected to the circuit board 151B, and 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 magnetic conductors 12B through each of the connecting 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 20A when being driven to rotate. In other words, the swinging position of the magnetic conductor 12B and the load of the flywheel 20A when being driven to rotate can be detected by detecting the resistance of the rotary potentiometer 152B.

[0178] 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.

[0179] Continuing to refer to the drawings Figures 22 to 25 The inner magnetic control device 10B further comprises two assemblies 16B, the end of the connecting 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 connecting arm 143B is rotatably mounted to the driven end 122A of the magnetic conductor 12B.

[0180] 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.

[0181] attached drawings Figure 26 and Figure 27 A variant of the flywheel assembly of the present application is shown in the attached drawings Figures 22 to 25 The flywheel assembly shown in the attached drawings is different from the flywheel assembly shown in the attached drawings Figure 26 and Figure 27 In this specific example of the flywheel assembly shown in the attached drawings, the electrically conductive element 18B of the inner magnetic control device 10B is rigid, and one end of the electrically conductive element 18B is rotatably mounted to the end of one of the conductors 13B, and the other end of the electrically conductive element 18B is rotatably mounted to the end of the adjacent conductor 13B. When the magnet conductor 12B drives the conductor 13B to swing, the electrically conductive element 18B can rotate relative to the conductor 13B to ensure that the electrically conductive element 18B is always electrically conductive connected to the adjacent two conductors 13B. When the flywheel 20A 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 can be balanced through the electrically conductive element 18B to electrically connect the adjacent two conductors 13B, so as to help the flywheel 20A to rotate smoothly and reduce vibration, which is crucial for improving user experience and reducing vibration noise of fitness equipment using the flywheel assembly.

[0182] Further, the electrically conductive element 18B includes a first electrically conductive section 181B and a second electrically conductive section 182B, one end of the first electrically conductive section 181B and one end of the second electrically conductive section 182B are rotatably mounted, the other end of the first electrically conductive section 181B is rotatably mounted to the end of one of the conductors 13B, and the other end of the second electrically conductive section 182B is rotatably mounted to the end of the other conductor 13B, so that the flexibility of the electrically conductive element 18B can be greatly improved, thereby avoiding the situation that the electrically conductive element 18B and the mounting position of the conductor 13B are stuck when the magnet conductor 12B drives the conductor 13B to swing. Optionally, in other examples of the flywheel assembly of the present application, the electrically conductive section of the electrically conductive element 18B can be more than three.

[0183] attached Figures 28 to 33 Another inner magnetic control device 10C of the flywheel assembly according to a second preferred embodiment of the present application is shown, wherein the flywheel 20A is configured to generate rotation relative to the inner magnetic control device 10C.

[0184] In particular, the inner magnetic control device 10C includes a housing 11C, at least one magnetic conductor 12C movably disposed in the housing 11C, and at least one conductor 13C disposed in the magnetic conductor 12C and outside the magnetic conductor 12C. The inner magnetic control device 10C is disposed in the flywheel space 213A of the flywheel body 21A such that the conductor 13C is held between the magnetic conductor 13C and the magnetic element 22A. When the flywheel 20A is driven to generate rotation relative to the inner magnetic control device 10C, the conductor 13C cuts the magnetic flux of the magnetic field formed between the magnetic element 22A and the magnetic conductor 12C to allow the flywheel 20A to obtain load. By changing the magnetic conductor 12C, the strength of the magnetic field formed between the magnetic element 22A and the magnetic conductor 12C is changed to adjust the load that the flywheel 20A can obtain.

[0185] In the flywheel assembly of the present invention, by arranging the magnetic element 22A on the flywheel body 21A, arranging the magnetizer 12C on the shell 11C, arranging the conductor 13C on the magnetizer 12C, and the flywheel body 21A providing the air flow channel 214A, on the first hand, the flywheel body 21A and the magnetic element 22A can be used together as the counterweight part of the flywheel 20A, so as to help reduce the cost of the flywheel assembly. On the second hand, when the flywheel 20A is driven to rotate relative to the internal magnetic control device 10C, the conductor 13C cuts the magnetic flux lines in the middle of the magnetic field formed between the magnetizer 12C and the magnetic element 22A, so that the flywheel 20A obtains a load, so as to help efficiently utilize the magnetic field and reduce the requirements for the magnetic field strength. On the third hand, when the flywheel 20A is driven When the flywheel 20A is driven to rotate relative to the internal magnetic control device 10C, it is subjected to centrifugal force, and the magnetic element 22A can fit tightly against the ring 212A of the flywheel body 21A to prevent the magnetic element 22A from falling off. Fourthly, after the heat generated by the conductor 13C 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. Fifthly, when the flywheel 20A is driven to rotate relative to the internal magnetic control device 10C, external gas is guided to flow through the gap formed between the internal magnetic control device 10BC and the flywheel 20A to take away heat, thereby quickly reducing the temperature of the magnetic element 22A itself and the surrounding environment and reducing the operating temperature of the internal magnetic control device 10C.

[0186] In addition, the heat dissipation capacity of the flywheel assembly of the present invention is adaptive, and increases with the increase of the rotation speed of the flywheel 20A, and the flywheel assembly does not need to be powered during the heat dissipation process, which is conducive to simplifying the structure of the flywheel assembly and improving the reliability of the flywheel assembly.

[0187] It is understandable that Figures 15 to 20 The flywheel assembly shown is the same as the one in the attached Figures 28 to 33 In the particular example of the flywheel assembly shown, the inner magnetic control device 10C and the flywheel 20A are assembled via the mounting shaft 30A and the flange 40A, such that the flywheel 20A is configured to rotate relative to the inner magnetic control device 10C.

[0188] Specifically, the outer shell 11C of the inner magnetic control device 10C has a shell through hole 1101B which penetrates through opposite sides of the outer shell 11C, and after the inner magnetic control device 10C is installed in the flywheel space 213A of the flywheel body 21A of the flywheel 20A, the shell through hole 1101C of the outer shell 11C and the flywheel through hole 2101A of the flywheel body 21A correspond to each other, wherein after the flange 40A fixedly arranged on the mounting shaft 30A sequentially passes through the shell through hole 1101C of the outer shell 11C and the flywheel through hole 2101A of the flywheel body 21A at one end of the mounting shaft 30A, the flange 40A is locked to the outer shell 11C, so that the inner magnetic control device 10C is assembled on the flywheel 20A, and the flywheel 20A is allowed to rotate relative to the inner magnetic control device 10C around the mounting shaft 30A.

[0189] With reference to the accompanying drawings Figures 28 to 33 The inner magnetic control device 10C further comprises a driving unit 14C arranged in the outer shell 11C. The magnetically permeable body 12C has a pivot end 121C and a driven end 122C corresponding to the pivot end 121C, wherein the pivot end 121C of the magnetically permeable body 12C is rotatably mounted on the outer shell 11C, and the driven end 122C of the magnetically permeable body 12C is drivingly connected to the driving unit 14C. The driving unit 14C is arranged to drive the magnetically permeable body 12C to swing relative to the outer shell 11C, so as to change the positions of the magnetic element 22C and the magnetically permeable body 12C, thereby changing the magnetic field strength formed between the magnetic element 22C and the magnetically permeable body 12C. It can be understood that when the driving unit 14C drives the magnetically permeable body 12C to swing relative to the outer shell 11C, the magnetically permeable body 12C drives the conductor 13C to swing synchronously.

[0190] Preferably, the magnetically permeable body 12C is curvedly extended between the pivot end 121C and the driven end 122C, so that the magnetically permeable body 12C is arc-shaped, and the shape of the outer side of the magnetically permeable body 12C is substantially the same as the shape of the periphery of the outer shell 11C.

[0191] Preferably, the conductor 13C is arc-shaped, and the curvature of the conductor 13C matches the curvature of the magnetically permeable body 12C, so that the conductor 13C is arranged on the magnetically permeable body 12C in a manner that the conductor 13C and the magnetically permeable body 12C face and fit each other.

[0192] It is worth mentioning that the manner in which the conductor 13C is arranged on the magnet 12C is not limited in the flywheel assembly of the present invention. For example, glue can be used to bond the conductor 13C and the magnet 12C to set the conductor 13C on the magnet 12C, or the conductor 13C and the magnet 12C can be riveted to set the conductor 13C on the magnet 12C.

[0193] Preferably, the number of the magnetic conductors 12C and the conductors 13C of the internal magnetic control device 10C is more than two, one conductor 13C is provided on the outside of each magnetic conductor 12C, and the two or more magnetic conductors 12C are symmetrically arranged. Figures 28 to 33 In the illustrated example of the flywheel assembly, the number of the magnetizers 12C and the number of the conductors 13C of the inner magnetic control device 10C are both two, and the two magnetizers 12C are centrally symmetrically arranged. Alternatively, in other examples, the two magnetizers 12C are axially symmetrically arranged.

[0194] Continue to refer to the attached Figures 28 to 33 The drive unit 14C is capable of simultaneously driving the two magnetizers 12C to swing with the same amplitude. Specifically, the drive unit 14C includes a drive motor 141C, a drive ring 142C, and two linkage arms 143C, wherein the drive motor 141C is mounted on the housing 11C, the drive ring 142C is rotatably mounted on the housing 11C and is drivably connected to the drive motor 141C, wherein one end of each linkage arm 143C is rotatably mounted on each of the opposite sides of the drive ring 142C, and the other end of each linkage arm 143C is rotatably mounted on the driven end 122C of each magnetizer 12C. When the driving motor 141C drives the driving ring 142C to rotate, the driving ring 142C drives each of the magnetizers 12C to swing through each of the linkage arms 143C, thereby changing the intensity of the magnetic field formed between the magnetic element 22C and the magnetizer 12C.

[0195] Specifically, refer to the attached Figure 28 and Figure 30When the driving motor 141C drives the driving ring 142C to rotate clockwise, the driving ring 142C drives each of the magnet conductors 12C to swing inwardly through each of the connecting arms 143C to allow each of the magnet conductors 12C to swing from the maximum swing position to the minimum swing position respectively, correspondingly, when the driving motor 141C drives the driving ring 142C to rotate counterclockwise, the driving ring 142C drives each of the magnet conductors 12C to swing outwardly through each of the connecting arms 143C to allow each of the magnet conductors 12C to swing from the minimum swing position to the maximum swing position respectively.

[0196] It can be understood that when each of the magnet conductors 12C is at the maximum swing position, the flywheel assembly forms the strongest magnetic field strength between the magnetic element 22C and the magnet conductor 12C, correspondingly, when each of the magnet conductors 12C is at the minimum swing position, the flywheel assembly forms the weakest magnetic field strength between the magnetic element 22C and the magnet conductor 12C, therefore, when each of the magnet conductors 12C swings from the maximum swing position to the minimum swing position respectively, the flywheel assembly forms the magnetic field strength between the magnetic element 22C and the magnet conductor 12C gradually weakens, correspondingly, when each of the magnet conductors 12C swings from the minimum swing position to the maximum swing position respectively, the flywheel assembly forms the magnetic field strength between the magnetic element 22C and the magnet conductor 12C gradually strengthens.

[0197] Continuing to refer to the drawings Figures 28 to 33 The housing 11C further comprises a disc-shaped first housing 111C and a disc-shaped second housing 112C, and has a housing space 1102C, a peripheral opening 1103C, and two communication passages 1104C. The first housing 111C has a first ring body 1111C, and the second housing 112C has a second ring body 1121C. The first housing 111C and the second housing 112C are installed in a corresponding manner of the first ring body 1111C and the second ring body 1121C, so as to form the housing space 1102C at the inner side of the first ring body 1111C and the second ring body 1121C, form the peripheral opening 1103C at the outer side of the first ring body 1111C and the second ring body 1121C, and form the communication passage 1104C between the first ring body 1111C and the second ring body 1121C, which communicates the housing space 1102C and the peripheral opening 1103C.

[0198] The opposite sides of the pivot end 121C of the magnetic conductor 12C are rotatably mounted to the edges of the first housing 111C and the second housing 112C, respectively, to rotatably mount the pivot end 121C of the magnetic conductor 12C to the edges of the housing 11C, and the magnetic conductor 12C is allowed to swing at the peripheral opening 1103C of the housing 11C. The driving motor 141C and the driving ring 142C of the driving unit 14C are located at the housing space 1102C of the housing 11C, respectively, and each of the linkage arms 143C extends from the housing space 1102C of the housing 11C to the peripheral opening 1103C through each of the communication passages 1104C of the housing 11C, to rotatably mount one end of each of the linkage arms 143C to each of the opposite sides of the driving ring 142C, and to rotatably mount the other end of each of the linkage arms 143C to the driven end 122C of each of the magnetic conductors 12C, respectively.

[0199] Further, the first housing 111C has a plurality of first mounting posts 1112C disposed outside the first ring body 1111C, and the second housing 112C has a plurality of second mounting posts 1122C disposed outside the second ring body 1121C, wherein each of the first mounting posts 1112C of the first housing 111C and each of the second mounting posts 1122C of the second housing 112C are mounted and supported to each other, to fixedly mount the first housing 111C and the second housing 112C, and to avoid the first housing 111C and the second housing 112C from being deformed. Preferably, screws are allowed to be mounted to the first mounting posts 1112C of the first housing 111C and the second mounting posts 1122C of the second housing 112C, to fixedly mount the first housing 111C and the second housing 112C. Preferably, the first mounting posts 1112C of the first housing 111C are adjacent to the first ring body 1111C, and the second mounting posts 1122C of the second housing 112C are adjacent to the second ring body 1121C, to avoid the first mounting posts 1112C of the first housing 111C and the second mounting posts 1122C of the second housing 112C from affecting the swinging of the magnetic conductors 12C to the minimum swing position.

[0200] Now turning to the drawings Figures 28 to 33The driving motor 141C of the driving unit 14C is fixedly mounted to the first housing 111C of the housing 11C. The first housing 111C has a boss 1113C, wherein the driving ring 142C is rotatably sleeved to the boss 1113C of the first housing 111C, so that the driving ring 142C can rotate to drive the magnet conductor 12C to swing inwardly or outwardly when being driven by the driving motor 141C.

[0201] Further, the driving unit 14C comprises a transmission gear set 144C for transmitting the power outputted by the output shaft 1411C of the driving motor 141C to the driving ring 142C, so as to drive the driving ring 142C to rotate relative to the housing 11C to drive the magnet conductor 12C to swing inwardly or outwardly.

[0202] Specifically, referring to the accompanying drawings, Figures 28 to 33 The driving ring 142C has a row of first ring teeth 1421C, wherein the transmission gear set 144C is composed of a plurality of meshed gears 1441C, which are rotatably mounted to the first housing 111C and the second housing 112C respectively in the housing space 1102C of the housing 11C. One of the gears 1441C is meshed with the output shaft 1411C of the driving motor 141C, and another of the gears 1441C is meshed with the first ring teeth 1421C of the driving ring 142C. Thus, when the driving motor 141C outputs power in the form of rotation of the output shaft 1411C, the power can be transmitted to the driving ring 142C through the transmission gear set 144C to drive the driving ring 142C to rotate relative to the housing 11C to drive the magnet conductor 12C to swing inwardly or outwardly.

[0203] It is worth mentioning that the number of the gears 1441C in the transmission gear set 144C is not limited in the flywheel assembly of the present application. For example, in the specific example of the flywheel assembly of the present application shown in FIG. 1, the number of the gears 1441C in the transmission gear set 144C is three. Figures 28 to 33

[0204] Continuing to refer to the accompanying drawings, Figures 28 to 33 ​The driving unit 14C further comprises an auxiliary gear 145C rotatably mounted in the housing space 1102C of the housing 11C, wherein the driving ring 142C has a second set of ring teeth 1422C, and the second set of ring teeth 1422C of the driving ring 142C is engaged with the auxiliary gear 145C to avoid the driving ring 142C from tilting when the driving ring 142C is driven, thereby ensuring the driving ring 142C to rotate stably and reliably relative to the housing 11C.

[0205] With reference to the accompanying drawings, in which Figures 28 to 33 The inner magnetic control device 10C further comprises a potential control unit 15C, which comprises a circuit board 151C and a rotary potentiometer 152C connected to the circuit board 151C, and the driving motor 141C is connected to the circuit board 151C, wherein the rotary potentiometer 152C has a mounting end 1521C and a rotating shaft end 1522C corresponding to the mounting end 1521C, and the mounting end 1521C of the rotary potentiometer 152C is mounted on the first housing 111C, and the auxiliary gear 145C is mounted on the rotating shaft end 1522C of the rotary potentiometer 152C. When the driving motor 141C drives each of the magnetic conductors 12C to swing inwards or outwards through each of the connecting arms 143C by driving the driving ring 142C to rotate, the driving ring 142C drives the auxiliary gear 145C to rotate, and at the same time, the auxiliary gear 145C drives the rotating shaft end 1522C of the rotary potentiometer 152C to rotate to change the resistance of the rotary potentiometer 152C. It can be understood that the resistance of the rotary potentiometer 152C is related to the rotating position of the driving ring 142C, and the rotating position of the driving ring 142C determines the swinging position of the magnetic conductor 12C, and further determines the load of the flywheel 20A when being driven to rotate. In other words, the swinging position of the magnetic conductor 12C and the load of the flywheel 20A when being driven to rotate can be detected by detecting the resistance of the rotary potentiometer 152C.

[0206] Preferably, the circuit board 151C of the potential control unit 15C is mounted on the first housing 111C of the housing 11C. Preferably, the circuit board 151C is retained in the housing space 1102C of the housing 11C to hide the circuit board 151C.

[0207] With reference to the accompanying drawings, in which Figures 28 to 33The inner magnetic control device 10C further comprises two sets of assemblies 16C, the end of the linkage arm 143C of the driving unit 14C is rotatably mounted on the assemblies 16C, and the assemblies 16C are mounted on the driven end 122C of the magnetic conductor 12C, so that the end of the linkage arm 143C is rotatably mounted on the driven end 122C of the magnetic conductor 12C.

[0208] Preferably, the conductor 13C has two avoiding spaces 131C extending from the inner wall to the outer wall of the conductor 13C, wherein the avoiding spaces 131C of the conductor 13C are located corresponding to the assemblies 16C, so as to allow the conductor 13C to avoid the assemblies 16C when the magnetic conductor 12C swings outward, thereby avoiding the assemblies 16C affecting the magnetic conductor 12C to swing to the maximum swing position. Preferably, the avoiding spaces 131C of the conductor 13C extend from the inner wall to the outer wall of the conductor 13C.

[0209] Continuing to refer to the drawings, Figure 29 The adjacent conductors 13C of the inner magnetic control device 10C are electrically conductive connected through the shell 11C, and the shell 11C is always electrically conductive connected to the adjacent conductors 13C when the magnetic conductor 12C drives the conductors 13C to swing. When the flywheel 20A is driven to rotate relative to the inner magnetic control device 10C, eddy current will be generated in each conductor 13C due to cutting magnetic induction lines, and the eddy current generated by the adjacent two conductors 13C can be balanced through the shell 11C to electrically connect the adjacent two conductors 13C, so as to help the flywheel 20A to rotate smoothly and reduce vibration, which is crucial for improving user experience and reducing vibration noise of the fitness equipment.

[0210] Further, the housing 11C has at least two pairs of conductive grooves 113C, each pair of the conductive grooves 113C is composed of a first conductive groove 1131C and a second conductive groove 1132C adjacent to each other, wherein the conductor 13C has at least a first conductive post 132C at the end corresponding to the driven end 122C of the magnet conductor 12C, the first conductive post 132C is slidably installed in the first conductive groove 1131C of the housing 11C, and the first conductive post 132C of the conductor 13C contacts the inner wall of the housing 11C for forming the first conductive groove 1131C, wherein the conductor 13C has at least a second conductive post 133C at the end corresponding to the pivot end 121C of the magnet conductor 12C, the second conductive post 133C is slidably installed in the second conductive groove 1132C of the housing 11C, and the second conductive post 133C of the conductor 13C contacts the inner wall of the housing 11C for forming the second conductive groove 1132C, so that the housing 11C can reliably conduct adjacent two conductors 13C.

[0211] Reference is made to the accompanying drawings that show by way of example Figure 30 and Figures 28 to 33When the driving motor 141C drives the driving ring 142C to rotate clockwise, the driving ring 142C drives each of the magnet conductors 12C to swing inwardly through each of the connecting arms 143C to allow each of the magnet conductors 12C to swing from the maximum swing position to the minimum swing position respectively, and when each of the magnet conductors 12C swings from the maximum swing position to the minimum swing position respectively, the first conductive column 132C of the conductor 13C slides along the track formed by the first conductive recess 1131C of the housing 11C in a manner that always contacts the inner wall of the housing 11C for forming the first conductive recess 1131C, and the second conductive column 133C of the conductor 13C slides along the track formed by the second conductive recess 1132C of the housing 11C in a manner that always contacts the inner wall of the housing 11C for forming the second conductive recess 1132C. Correspondingly, when the driving motor 141C drives the driving ring 142C to rotate counterclockwise, the driving ring 142C drives each of the magnet conductors 12C to swing outwardly through each of the connecting arms 143C to allow each of the magnet conductors 12C to swing from the minimum swing position to the maximum swing position respectively, and when each of the magnet conductors 12C swings from the minimum swing position to the maximum swing position respectively, the first conductive column 132C of the conductor 13C slides along the track formed by the first conductive recess 1131C of the housing 11C in a manner that always contacts the inner wall of the housing 11C for forming the first conductive recess 1131C, and the second conductive column 133C of the conductor 13C slides along the track formed by the second conductive recess 1132C of the housing 11C in a manner that always contacts the inner wall of the housing 11C for forming the second conductive recess 1132C.

[0212] Now turning to the drawings ​ The housing 11C further comprises at least two conductive portions 114C, the conductive portions 114C are mounted to the first housing 111C, each pair of the conductive grooves 113C is formed in each of the conductive portions 114C to conductively connect two adjacent conductors 13C by the conductive portions 114C.
