[0030] The magnetic control wheel is a structure that uses magnetic force and electromagnetic induction to provide smooth braking resistance. It can be used as a counterweight to provide braking resistance for fitness equipment such as elliptical machines and exercise bikes, so that users can achieve corresponding load exercises through fitness equipment. The magnetic control wheel is mainly made of electromagnets and flywheels. The electromagnet is connected to an external power source to form an electromagnetic force to act on the flywheel, thereby achieving a braking and deceleration control effect on the flywheel. However, the operation of this magnetic control wheel depends on an external power source. Once a power outage occurs, the electromagnet cannot control the deceleration and braking of the flywheel, and the magnetic control wheel will not work properly. In addition, this magnetic control wheel needs to continuously consume external electricity to maintain operation, which is not conducive to energy conservation and environmental protection.

[0031] The following is the attached Figure 1 To Attachment Figure 6 , describing the follow-up controlled magnetically controlled wheel device of the embodiment of the utility model, which can utilize an external power source to generate electricity and form corresponding braking resistance, is energy-saving and environmentally friendly, and has few restrictions on use.

[0032] Reference Figures 1 to 4 , a magnetically controlled wheel device with follow-up control in this embodiment includes:

[0033] The stator assembly 100 comprises a support 110, a stator base 120, n stator cores 130 and n groups of stator coil windings 140 corresponding to each stator core 130, wherein n is an integer greater than 1, the stator base 120 is fixedly connected to the support 110, the stator base 120 is annular, all the stator cores 130 are evenly distributed and fixedly connected to the outer circumferential surface of the stator base 120, the central axis of the stator core 130 is arranged along the radial direction of the stator base 120, the cross-sectional area of ​​the stator core 130 perpendicular to the central axis of the stator core 130 decreases in a direction away from the center of the stator base 120, so as to form sufficient winding space for the stator coil winding 140 to be wound and arranged, the transverse dimension of the stator core 130 perpendicular to the central axis decreases in a radial direction toward a side away from the circle of the stator base 120, and each group of stator coil windings 140 is respectively wound and connected to the corresponding stator core 130;

[0034] The rotor assembly 200 is arranged on one side of the stator assembly 100, and includes a rotating shaft 210, a flywheel 220, a steel ring 230 and a plurality of magnet blocks 240. The rotating shaft 210 is arranged through the center of the stator seat 120, and the rotating shaft 210 is rotatably connected to the support 110. Specifically, the rotating shaft 210 is rotatably connected to the support 110 through a bearing. The flywheel 220 is annular and surrounds the stator seat 120 and each stator core 130 connected thereto. There are intervals between the flywheel 220 and the stator seat 120 and the stator core 130 respectively. The flywheel 220 is fixedly connected to the rotating shaft 210, and the rotating shaft 210 is located at the center of the flywheel 220. The steel ring 230 is fixedly connected to the outer circumferential surface of the flywheel 220. All the magnet blocks 240 are evenly distributed and connected to the inner circumferential surface of the flywheel 220, so that the stator coil winding 140 is located within the range of action of the permanent magnetic field of the magnet blocks 240.

[0035] The electromagnet 300 is located outside the rotor assembly 200 and is arranged on the side of the steel ring 230 away from the flywheel 220, that is, the electromagnet 300 is arranged on the outer circumferential surface of the steel ring 230, so that the steel ring 230 is located within the range of the induced magnetic field of the electromagnet 300. The electromagnet 300 is electrically connected to the stator coil winding 140, so that the current generated by the electromagnetic induction of the stator coil winding 140 drives the electromagnet 300 to work, so that the electromagnet 300 generates an electromagnetic force acting on the steel ring 230, thereby braking the flywheel 220.

[0036] The stator core 130 is evenly distributed on the circumferential surface of the stator seat 120 through a circular trajectory, and a stator coil winding 140 is wound around the stator core 130. A magnet block 240 matching the stator coil winding 140 is arranged on the inner side of the flywheel 220. When the flywheel 220 is driven to rotate by an external power through the rotating shaft 210, a relative movement occurs between the magnet block 240 rotating with the flywheel 220 and the stator coil winding 140. The stator coil winding 140 generates an induced current through electromagnetic induction and supplies power to the electromagnet 300. Under the action of the electromagnet 300, the outer steel ring 230 of the flywheel 220 The movement is hindered by the electromagnetic force, and the flywheel 220 can be braked. The braking effect of the flywheel 220 is generated following the movement of the flywheel 220, and can be used as a counterweight in fitness equipment such as elliptical machines and fitness bikes. By driving the flywheel 220 to rotate and self-generating, the flywheel 220 can provide resistance to its rotation, which can form a counterweight load effect, thereby achieving the purpose of fitness training. The magnetically controlled wheel device supplies power to the electromagnet 300 through follow-up power generation, can operate independently of an external power supply, has few restrictions on use, has a wide range of applications, and can save external power consumption, saving energy and being environmentally friendly.

[0037] In addition, the cross-sectional area of ​​the stator core 130 decreases toward the side away from the center of the stator seat 120. By reducing the occupied space of the corresponding structure at one end of the stator core 130 close to the flywheel 220, sufficient winding space can be provided for the setting of the stator coil winding 140, thereby effectively increasing the effective number of turns of the stator coil winding 140 within the range of action of the permanent magnetic field of the magnet block 240, and further effectively increasing the induced current generated by the stator coil winding 140, which can effectively ensure that the braking resistance formed by the electromagnet 300 on the flywheel 220 through the steel ring 230 is sufficient and reliable.

[0038] Specifically, the stator core 130 can be configured as a truncated cone, a prism or other structure, the lower base of the stator core 130 is disposed on the outer circumferential surface of the stator seat 120 , and the upper base of the stator core 130 is located on the side of the lower base away from the stator seat 120 .

[0039] It can be understood that the stator assembly 100 also includes n limit plates 150, each of which is fixedly connected to one end of each stator core 130 away from the stator seat 120, and the limit plate 150 is used to limit the position of the stator coil winding 140, which can effectively improve the stability of the position of the stator coil winding 140, thereby effectively improving the working performance of the magnetic control wheel device.

[0040] It is understandable that the stator assembly 100 further includes a circular positioning plate 160 whose central notch is used to make room for the rotating shaft 210 . The stator seat 120 is fixedly connected to one side of the positioning plate 160 , and the side of the positioning plate 160 away from the stator seat 120 is fixedly connected to the support 110 .

[0041] It can be understood that the rotor assembly 200 also includes a wheel plate 250, which is fixedly connected to the flywheel 220. The wheel plate 250 is located on the side of the stator seat 120 away from the positioning plate 160, and a gap is formed between the wheel plate 250 and the stator seat 120. The wheel plate 250 is fixedly connected to the rotating shaft 210. By respectively arranging the positioning plate 160 and the wheel plate 250 on the opposite sides of the stator seat 120 to respectively realize the corresponding connection and installation functions, the gravity distribution of the magnetic control wheel device can be effectively balanced, thereby effectively improving the stability during operation.

[0042] Specifically, one end of the rotating shaft 210 is fixedly connected to a driving wheel, and the driving wheel is used to transmit external power input to the rotating shaft 210 to enable the rotating shaft 210 to rotate.

[0043] It can be understood that the electromagnet 300 includes an electromagnetic support 310, an electromagnetic core iron 320 and an electromagnetic coil winding 330. The electromagnetic core iron 320 is connected to the support 110. The electromagnetic core iron 320 is located outside the outer circumferential surface of the flywheel 220, and the flywheel 220 is located within the magnetic field action range of the electromagnetic core iron 320. The electromagnetic support 310 is sleeved on the electromagnetic core iron 320, and the electromagnetic coil winding 330 is wound on the electromagnetic support 310. The electromagnetic coil winding 330 is electrically connected to the stator coil winding 140 so that the induced current generated by electromagnetic induction by the stator coil winding 140 is supplied to the electromagnetic coil winding 330, and the electromagnetic coil winding 330 then uses these currents to cooperate with the electromagnetic core iron 320 to form an electromagnetic force to brake the flywheel 220 through the steel ring 230.

[0044] It can be understood that the magnet block 240 is in the shape of a tile. By setting the tile-shaped magnet block 240, and the tile-shaped magnet block 240 is set on the inner circumferential surface of the flywheel 220, the distance between the magnet block 240 and the stator core 130 distributed in a circular trajectory is equal, which can effectively ensure the stability of the electromagnetic induction effect between the iron block and the stator coil winding 140, and can effectively improve the stability of the induced current produced by the stator coil winding 140.

[0047] A plurality of fan blades 260 are provided on the side of the flywheel 220 away from the wheel plate 250. The fan surface of the fan blades 260 is inclined toward one side of the stator coil winding 140. The fan blades 260 are used to dissipate heat from the stator coil winding 140. Specifically, the fan blades 260 rotate with the flywheel 220 to accelerate the air flow around the stator coil winding 140, thereby improving the heat dissipation efficiency of the stator coil winding 140.
