In this way, the present invention is used in operation, so that the user needs to adjust the resistance of the wheel body (13) to rotate during the process of using the flywheel (1) for exercise and stepping on the wheel body (13) to rotate. , the user can rotate by the control handle (253) of the control lever (25), so that the control lever (25) rotates with the control handle (253) [please refer to the seventh picture again During the rotation of the control rod (25), the threaded section (251) at the bottom end of the control rod (25) will gradually move toward the connecting hole ( 245), and let the top support rod (24) rise, while the top support rod (24) rises, the positioning section (241) of the top support rod (24) will drive the shaft (241) together. 35) Move upward to make it have the function of vertical rotation and upward movement. At this time, the sliding sleeves (351) set at both ends of the shaft member (35) will be in the long grooves of the two side pieces (32). (321) is moved upwards, and the side piece (32) is gradually lifted upwards away from the wheel body (13), so that the magnetic pieces (34) on the inner side of the two side pieces (32) gradually decrease with the wheel body (13). 13) of the induction area to reduce the eddy current generated, which reduces the resistance when the wheel body (13) rotates, making it easier for the user to step on the fitness process. When the two side pieces (32) are moved upwards When reaching the upper starting point at the highest point, the induction area between the magnetic element (34) and the wheel body (13) is the smallest, so The eddy current generated is the smallest, and the resistance of the wheel body (13) when it is rotated is the smallest.

In addition, when the user rotates the control handle (253) of the control lever (25) in the other direction, the control lever (25) rotates in the other direction along with the control handle (253). And refer to the ninth picture of another adjustment state action diagram of the present creation], and the screw connection section (251) at the bottom end of the control rod (25) will gradually move towards the connection hole of the top support rod (24). (245) moves outward to make the top strut (24) descend, and the positioning section (241) of the top strut (24) will drive the shaft (35) to move down together, so that it has a straight Rotation and downward movement function, at this time, the sliding sleeves (351) sleeved on the two ends of the shaft member (35) will move downward in the long grooves (321) of the two side pieces (32), and The side piece (32) is gradually pressed downward toward the wheel body (13), so that the magnetic elements (34) on the inner side of the two side pieces (32) gradually increase the induction area with the wheel body (13), so that The increase in the generated eddy current will increase the resistance of the wheel body (13) when it rotates, making it more difficult for the user to step on the fitness process. The two side pieces (32) are moved down to the lowest point. When the magnetic element (34) and the wheel body (13) have the largest inductive area, the generated eddy current is the largest, and the resistance when the wheel body (13) rotates is the largest (please refer to Figure 10 together).

Also, please refer to the schematic diagram of the braking state in Figure 11. When the user wants to brake the wheel body (13) and stop the rotation of the wheel body (13), he only needs to use the The control handle (253) presses the control rod (25) downward, at this time the control rod (25) will drive the top support rod (24) to descend rapidly, and make the top support rod (24) drive the top support rod (24) together The shaft member (35) moves downward, so that the sliding sleeves (351) sleeved at both ends of the shaft member (35) rapidly move downward in the elongated grooves (321) of the two side pieces (32), When the side piece (32) is rapidly pressed downward toward the direction of the wheel body (13) to the lowest starting point, since the induction area between the magnetic element (34) and the wheel body (13) is the largest, the resulting The eddy current is the largest, and the resistance when the wheel body (13) rotates is the largest, so that the eddy current brake will be formed, and the wheel body (13) will be completely braked, and the control rod (25) will be pressed down. At the same time, the upper abutting protrusion (252) on the outer edge of the control rod (25) will press down the upper abutting member (262) together with the elastic element (26), so that the elastic element (26) is In the compressed state, when the wheel body (13) is completely stopped and the braking action is completed, the user releases the control handle (253) together with the control rod (25) and presses down, the elastic element (26) recovers The elastic force will push the control rod (25) back to its original position.

From the above, it can be seen from the description of the use and implementation of this creation that, compared with the existing technical means, this creation is not only simpler in its overall structure design, but also relatively more convenient in the operation and use process. The utility model is convenient, can effectively reduce the production cost, and can achieve better training effect, and the utility model can be more effective in its overall implementation and use.
