[0061] Compared to the existing method of dispersing functional components, this core module integrates the flywheel assembly, drag adjustment assembly, power generation assembly, and battery assembly on the mounting frame, forming a single core module with a compact structure.

[0062] In one embodiment of this utility model, see Figure 2 and Figure 4The resistance adjustment assembly 7 includes: a drive motor 11, mounted on one side wall of the mounting bracket 6; a lead screw 12, connected to the output end of the drive motor 11, rotatably mounted on one side wall of the mounting bracket 6; a gear 13, rotatably mounted on one side wall of the mounting bracket 6, meshing with the lead screw 12; and a mounting base 14, mounted on the gear 13, with an N / S pole permanent magnet 15 disposed on the side wall of the mounting base 14 near the flywheel assembly 1. This allows adjustment of the relative position of the N / S pole permanent magnet 15 and the conductor plate 4, thereby adjusting the resistance experienced by the flywheel 5 during rotation and achieving continuous adjustment of riding resistance.
[0063] Optionally, a mounting bracket 6 is provided on one side wall, and the drive motor 11 is mounted in the mounting bracket.
[0064] Optionally, one end of the lead screw 12 is connected to the output end of the drive motor 11, and the other end of the lead screw 12 is rotatably mounted on the support, which is detachably mounted on the mounting bracket 1.

The rotor assembly 16 is fitted onto the stator assembly 17, and the rotor assembly 16 rotates synchronously with the multi-wedge wheel 3. In this way, electrical energy can be generated through electromagnetic induction to supply power to the resistance regulating assembly 7.
[0069] In one embodiment of this utility model, see Figure 2 , Figure 6 and Figure 7The power assembly 10 includes: a first rotating shaft 18, rotatably mounted on the frame 9, with a first drive wheel 19 sleeved on the first rotating shaft 18, and cranks 20 connected to both ends of the first rotating shaft 18; a second rotating shaft 21, rotatably mounted on a mounting bracket 6, passing through the mounting bracket 6; a second drive wheel 22, located at one end of the second rotating shaft 21, connected to the first drive wheel 19 via a belt drive; and a third drive wheel 23, located at the other end of the second rotating shaft 21, connected to the multi-wedge pulley 3 via a belt drive; and a pedal is mounted at the other end of the crank 20. This creates a two-stage transmission structure, allowing power input by pedaling, which drives the flywheel 5 to rotate, thus enabling cycling exercise.
[0070] In one embodiment of this utility model, see Figures 2 to 4 A belt tensioner 24 is rotatably mounted on the mounting bracket 6. The belt tensioner 24 is located between the third drive wheel 23 and the multi-wedge wheel 3, and abuts against the belt. In this way, the belt tension can be adjusted, which facilitates the third drive wheel 23 to drive the multi-wedge wheel 3 to rotate, and then drives the flywheel 5 to rotate.
[0071] Optionally, a support plate can be detachably installed at the bottom of the mounting bracket 6. The support plate has a guide groove extending longitudinally, and the pressure roller 24 is connected to the support plate by bolts. In this way, the installation position of the pressure roller 24 can be adjusted, making it convenient to adjust the tension of the belt.

The mounting bracket 6 and the locking block 27 are connected by bolts. In this way, the mechanism module can be quickly installed and removed, and it can be adapted to different models of the frame 9.
[0075] Optionally, the frame 9 is a high-strength metal frame.
[0076] According to a third aspect of this utility model, see [link to relevant documentation]. Figure 7 A stationary bike is provided, including the mechanism module described in the second aspect.
[0077] In one embodiment of this utility model, see Figures 1 to 7 The working process of the flywheel assembly, the movement module, and the exercise bike is briefly described below:
[0078] In use, this invention begins by stepping on the pedal, which drives the first drive wheel 19 to rotate via the crank 20. The belt drive between the first drive wheel 19 and the second drive wheel 22 then drives the second drive wheel 22 to rotate, which in turn drives the third drive wheel 23 to rotate. The belt drive between the third drive wheel 23 and the multi-wedge wheel 3 then drives the multi-wedge wheel 3 to rotate, which in turn drives the conductor plate 4 and the flywheel 5 to rotate, thus achieving the cycling exercise effect. The rotation of the conductor plate 4 creates relative motion with the N / S permanent magnet 15. The conductor plate 4 cuts the magnetic field lines, generating a magnetic field within it that opposes the N / S magnetic field. The relative movement between the permanent magnet 15 and the conductor plate 4 applies resistance to the flywheel 5, improving the cycling exercise effect. When the resistance needs to be adjusted, the drive motor 11 is started, which drives the lead screw 12 to rotate. Through the meshing transmission between the lead screw 12 and the gear 13, the gear 13 is driven to rotate, which in turn drives the mounting base 14 and the N / S permanent magnet 15 on it to rotate. This adjusts the relative position of the N / S permanent magnet 15 and the conductor plate 4, and adjusts the overlap area between the N / S permanent magnet 15 and the conductor plate 4, thereby adjusting the amount of resistance applied to the flywheel 5 and achieving different cycling exercise effects.
