Referring to fig. 1 to 6 of the drawings, a power generation assembly 100 according to a preferred embodiment of the present utility model will be disclosed and described in the following description, wherein the power generation assembly 100 is mounted to a machine frame 200 to form a body-building machine, and the power generation assembly 100 is capable of providing load and power when a user exercises using the body-building machine, so that the body-building machine may not need to be supplied with power from a utility power source, i.e., the body-building machine may not need to be designed to be connected to a power line of the utility power source, thereby facilitating the placement of the body-building machine at a suitable location in a home environment.

Specifically, the power generation assembly 100 includes a magnetic control portion 10, a generator 20, and a transmission portion 30. The magnetic control part 10 includes a flywheel 11 and an inner magnetic control device 12, the flywheel 11 includes a wheel disc 111 and a wheel ring 112, and has a flywheel space 113, the wheel ring 112 is disposed at one side of the wheel disc 111, the flywheel space 113 is formed between the wheel ring 112 and the wheel disc 111, the inner magnetic control device 12 is suspended in the flywheel space 113 of the flywheel 11, and the inner magnetic control device 12 is fixedly mounted to the equipment rack 200. The generator 20 is fixedly mounted to the equipment rack 200 such that the internal magnetic control device 12 is configured to remain stationary relative to the position of the generator 20. The transmission part 30 connects the rotor 21 of the generator 20 and the flywheel 11. When the flywheel 11 is driven to rotate relative to the inner magnetic control device 12, the flywheel 11 cuts the magnetic induction line of the inner magnetic control device 12 to obtain a load for a user to exercise, and meanwhile, the flywheel 11 drives the rotor 21 of the generator 20 to rotate through the transmission part 30 so as to enable the generator 20 to generate electricity to provide electric energy.

More specifically, the flywheel 11 has a flywheel perforated hole 114 penetrating through a center position of the wheel disc 111 such that the flywheel perforated hole 114 communicates with the flywheel space 113, wherein the inner magnetic control device 12 has a device perforated hole 121 penetrating through opposite sides of the inner magnetic control device 12 at a center position of the inner magnetic control device 12, wherein the magnetic control part 10 includes a fitting shaft 13, a middle portion of the fitting shaft 13 is fixedly installed to the device perforated hole 121 of the inner magnetic control device 12, and opposite ends of the fitting shaft 13 are respectively exposed to opposite sides of the inner magnetic control device 12, the inner magnetic control device 12 is suspended from the flywheel space 113 of the flywheel 11 in such a manner that one end portion of the fitting shaft 13 penetrates through the flywheel perforated hole 114 of the flywheel 11, and the flywheel 11 is configured to be rotatable about the fitting shaft 13, and opposite ends of the fitting shaft 13 are respectively fixedly installed to the frame 200. When the flywheel 11 is driven to rotate about the mounting shaft 13, the ring 112 of the flywheel 11 produces rotation relative to the inner magnetic control 12 to cut the magnetic induction lines of the inner magnetic control 12 to obtain a load for the user to exercise.

The specific construction of the internal magnetic control device 12 is shown in fig. 4-6. The internal magnetic control device 12 includes a housing 122, a driving unit 123, at least one swing arm 124, and at least one magnetic element 125, wherein the driving unit 123 and the swing arm 124 are respectively disposed on the housing 122, and the swing arm 124 is drivably connected to the driving unit 123, and the magnetic element 125 is disposed on the swing arm 124, so that the driving unit 123, the swing arm 124, and the magnetic element 1254 are integrated into a whole by the housing 122, wherein the device through hole 121 is formed on the housing 122. Preferably, the housing 122 is disc-shaped such that the inner magnetic control device 12 is disc-shaped overall, such that the shape of the inner magnetic control device 12 matches the shape of the flywheel 11.

In particular, turning to fig. 4-6, the swing arm 124 includes a curved extending swing arm body 1241 and at least one magnetic focusing portion 1242. The swing arm body 1241 has a pivot end 12411, a driven end 12412 corresponding to the pivot end 12411, and an abutment surface 12413 extending between the pivot end 12411 and the driven end 12412, the pivot end 12411 of the swing arm body 1241 is rotatably mounted to the housing 22, and the driven end 12412 of the swing arm body 1241 is drivably connected to the driving unit 123. The magnetic focusing part 1242 is disposed at a side of the swing arm body 1241 so as to protrude from the attaching surface 12413 of the swing arm body 1241, and an extending direction of the magnetic focusing part 1242 is identical to an extending direction of the swing arm body 1241. The magnetic element 125 is attached to the attaching surface 12413 of the swing arm main body 1241, so that the magnetism collecting portion 1242 shields at least a portion of the side edge of the magnetic element 125, and the magnetism collecting portion 242 collects the magnetic induction lines of the magnetic element 125 to reduce the magnetic leakage phenomenon, thereby improving the magnetic utilization rate of the internal magnetic control device 2.

Turning now to FIG. 6, the ring 112 of the flywheel 11 is positioned around the periphery of the inner magnetic control device 12 such that the magnetic elements 125 of the inner magnetic control device 12 and the inner wall of the ring 112 of the flywheel 11 are in a face-to-face relationship, in such a way that when the flywheel 11 is driven to rotate relative to the inner magnetic control device 12, the ring 112 of the flywheel 11 cuts the magnetic induction lines of the magnetic elements 125 of the inner magnetic control device 12 to load the flywheel 11 to assist the user in achieving exercise. In the power generation assembly 100 of the present utility model, the inner magnetic control device 12 can concentrate the magnetic induction line of the magnetic element 125 toward the rim 112 of the flywheel 11 by attaching the magnetic element 125 to at least a portion of the attaching surface 12413 and the magnetism collecting portion 1242 of the swing arm main body 1241 to shield the side of the magnetic element 125, thereby reducing the leakage of the magnetic induction line of the magnetic element 125 toward the rim 112 away from the flywheel 11, and thus improving the magnetic utilization of the inner magnetic control device 12.

Specifically, with continued reference to fig. 6, as the swing arm 124 swings inwardly, the swing arm 124 swings the magnetic element 125 inwardly to increase the distance between the magnetic element 125 and the rim 112 of the flywheel 11 to reduce the load that the flywheel 11 gets when driven to rotate. Accordingly, when the swing arm 124 swings outward, the swing arm 124 drives the magnetic element 125 to swing outward to reduce the distance between the magnetic element 125 and the ring 112 of the flywheel 11, so as to increase the load obtained when the flywheel 11 is driven to rotate.

Preferably, in one specific example of the power generation assembly 100 of the present utility model, the magnetism collecting portion 1242 of the swing arm 124 extends from the driven end 12412 of the swing arm body 1241 toward the pivoting end 12411, so that the magnetism collecting portion 1242 of the swing arm 124 can enhance the structural strength of the swing arm body 1241 while playing a role of magnetism collection, so as to avoid deformation of the swing arm body 1241 and ensure the reliability of the internal magnetic control device 12.

Still preferably, in a specific example of the power generation assembly 100 of the present utility model, the swing arm 124 includes two magnetic focusing portions 1242, and the opposite sides of the swing arm body 1241 are respectively provided with one magnetic focusing portion 1242, so as to form a positioning groove 1243 between the two magnetic focusing portions 1242 and the swing arm body 1241, and the abutting surface 12413 of the swing arm body 1241 forms a groove bottom of the positioning groove 1243 of the swing arm 124. After the magnetic element 125 is mounted on the attaching surface 12413 of the swing arm main body 1241, on one hand, the magnetic element 125 is positioned in the positioning groove 1243 of the swing arm 124 to avoid the dislocation problem of the magnetic element 125 relative to the swing arm 124, and on the other hand, the two magnetic focusing portions 1242 respectively shield the side edges of the two opposite sides of the magnetic element 125, so as to further improve the magnetic focusing effect.

Still preferably, in one specific example of the power generation assembly 100 of the present utility model, the distance dimension between the inner walls of the two magnetism collecting parts 1242 is matched to the distance dimension between the two sides of the magnetic element 125, so that after the magnetic element 125 is attached to the attaching face 12413 of the swing arm body 1241, the side face of the magnetic element 125 and the inner wall of the magnetism collecting part 1242 can also be attached to each other, that is, the attaching area of the magnetic element 125 and the magnetism collecting part 124 is increased, so that the magnetic element 125 is reliably attached to the swing arm 124. It will be appreciated that glue may be provided to attach the magnetic element 125 and the swing arm 124.

Specifically, the pivoting ends 12411 of the swing arm bodies 1241 of the two swing arms 124 are rotatably mounted to edges of the housing 122, respectively, and since the swing arm bodies 1241 are curvingly extended, the driven ends 12412 of the swing arm bodies 241 of the two swing arms 124 can be extended to the edges of the housing 122 to allow the driving unit 123 to drive the two swing arms 124 to swing inward or outward at edge positions of the housing 122. When the driving unit 123 drives the two swing arms 124 to swing inward, the swing arms 124 drive the magnetic elements 125 to swing inward synchronously and with the same amplitude to increase the distance between the magnetic elements 125 and the wheel ring 112 of the flywheel 11, thereby reducing the load obtained when the flywheel 11 is driven to rotate; accordingly, when the driving unit 123 drives the two swing arms 124 to swing outwardly, the swing arms 124 drive the magnetic elements 125 to swing outwardly synchronously and with the same amplitude, so as to reduce the distance between the magnetic elements 125 and the wheel ring 112 of the flywheel 11, thereby increasing the load obtained when the flywheel 11 is driven to rotate.

With continued reference to fig. 4 and 6, the driving unit 123 includes a driving wheel 1231 and two rigid connection members 1232, the driving wheel 1231 being rotatably mounted to an edge of the housing 122, opposite ends of each connection member 1232 being rotatably mounted to the edge of the driving wheel 1231 and the driven end 12412 of the swing arm body 1241 of each swing arm 124, respectively, wherein upon rotation of the driving wheel 1231 relative to the housing 122, the driving wheel 1231 simultaneously pulls the driven ends 12412 of the swing arm bodies 1241 of two swing arms 124 inward through the two connection members 1232 to increase a distance between the magnetic member 125 and the wheel ring 112 of the flywheel 11, or the driving wheel 1231 simultaneously pushes the driven ends 12412 of the swing arm bodies 1241 of two swing arms 124 outward through the two connection members 1232 to decrease a distance between the magnetic member 125 and the wheel ring 112 of the flywheel 11.

Specifically, turning to fig. 6, when the driving wheel 1231 is driven to rotate clockwise with respect to the housing 122, the driving wheel 1231 simultaneously pulls the driven ends 12412 of the swing arm bodies 1241 of the two swing arms 124 inward through the two connection members 1232, and the swing arms 124 swing the magnetic members 125 synchronously and with the same amplitude inward to increase the distance between the magnetic members 125 and the wheel ring 112 of the flywheel 11, thereby reducing the load obtained when the flywheel 11 is driven to rotate. Accordingly, when the driving wheel 1231 is driven to rotate counterclockwise with respect to the housing 122, the driving wheel 1231 simultaneously pushes the driven ends 2412 of the swing arm bodies 1241 of the two swing arms 124 outwardly through the two connection members 1232, and the swing arms 124 swing the magnetic members 125 outwardly synchronously and with the same amplitude to reduce the distance between the magnetic members 125 and the wheel ring 112 of the flywheel 11, thereby increasing the load obtained when the flywheel 111 is driven to rotate.

With continued reference to fig. 4-6, the housing 122 includes a first housing 1221 and a second housing 1222, and the housing 122 has an interior space 1223, a peripheral opening 1224 surrounding the interior space 1223, and at least one communication passage 1225 communicating with the interior space 1223 and the peripheral opening 1224, respectively, wherein the first housing 1221 and the second housing 1222 are mounted to each other to form the interior space 1223, the peripheral opening 1224, and the communication passage 1225 between the first housing 1221 and the second housing 1222.

When the flywheel 11 is driven to rotate relative to the inner magnetic control device 12, the flywheel 11 cuts the magnetic induction line of the inner magnetic control device 12 to obtain a load for a user to exercise, and meanwhile, the flywheel 11 drives the rotor 21 of the generator 20 to rotate through the gear set 30b so as to enable the generator 20 to generate electricity to provide electric energy.
