In the above embodiment, the brake plate 32 may be an arc-shaped plate, and the shape of the arc-shaped plate matches with the shape of the outer edge of the flywheel 31.

In the above embodiment, the magnet 37 (shown in fig. 2) is provided on the end surface of the brake pedal 32 on the side close to the flywheel 31. It should be noted that the magnet 37 may be one or a plurality of magnets arranged at intervals, and when the magnet 37 is a plurality of magnets, it includes a plurality of normal magnets and a plurality of strong magnets. Wherein a powerful magnet is arranged at one end of the brake plate 32 close to the brake cable. For example, six magnets 37 can be mounted on the brake plate 32, including two powerful magnets mounted near the end of the brake cable, when the two powerful magnets are closest to the flywheel 31, which is the time of greatest resistance, and four normal magnets. When the brake cable is pulled, the distance between the brake plate 32 and the flywheel 31 changes, the resistance of the magnet 37 to the flywheel 31 also changes, and the closer the brake plate 32 is to the flywheel 31, the greater the resistance.

In the above embodiment, in order to prevent the magnet 37 on the braking plate 32 from contacting the flywheel 31 and locking the flywheel 31 due to too small gap between the magnet and the flywheel 31, a non-magnetic retaining ring (not shown) may be sleeved on the outside of the flywheel 31 to prevent the flywheel 31 from contacting the braking plate 32. It should be noted that the retainer ring may be made of any material of any thickness as known in the art. For example, an aluminum ring having a thickness of 2mm is used.

In the above embodiment, as shown in fig. 5, a position limiting mechanism 6 may be provided between the other end of the brake pedal 32 and the frame 1, and the position limiting mechanism 6 is used to prevent the magnet 37 from contacting the flywheel 31. The limiting mechanism 6 includes a limiting plate 61, a limiting member 62, and a spring 63. The number of the limiting plates 61 is two, the first limiting plate 61 is fixed on the frame 1, the second limiting plate 61 is located below the first limiting plate 61 and connected to the other end of the brake plate 32, a limiting member 62 is disposed between the two limiting plates 61, the limiting member 62 is connected to the first limiting plate 61, and the limiting member 62 is used for limiting the distance between the brake plate 32 and the flywheel 31, so as to prevent the magnet 37 of the brake plate 32 from contacting the flywheel 31 and causing the flywheel 31 to be locked. The two ends of the spring 63 are respectively connected with the first and second limiting plates 61, and the arrangement of the spring 63 ensures that the length of the brake cable can be controlled by the regulating part 41, so as to adjust the distance between the magnet 37 and the flywheel 31. Specifically, when the brake cable is tightened, the fixing of the brake plate 32 is ensured by the tension of the spring 63; when the brake cable is released, the return of the brake plate 32 is driven by the recoil force of the spring 63.

In the above embodiment, the diameters of the transmission shaft 33, the rotating shaft 21 and the rotating shaft 22 can be increased, so as to increase the inertia of the running board 2 during operation.

When the device works, a user holds the holding end by hands, the running belt 23 is driven by running of two feet to rotate together with the

rotating shafts

21 and 22, the rotating shaft 21 drives the flywheel 31 to rotate together by rotation, when the user needs to change the motion resistance, the regulating part 41 is manually operated, so that the length of the brake cable extending out of the regulating part 41 is changed, when the brake cable is shortened, the other end of the brake cable pulls the brake plate 32 to rotate anticlockwise for a certain angle, the distance between the brake plate 32 and the flywheel 31 is reduced, the rotation resistance of the flywheel 31 is increased by the action of the magnet 37, the motion intensity of the user is further improved, and the running difficulty is increased. When the brake cable is extended, the other end of the brake cable pulls the brake plate 32 to rotate clockwise by a certain angle, so that the distance between the brake plate 32 and the flywheel 31 is increased, the effect of the magnet 37 on the flywheel 31 is reduced, and the rotation resistance of the running platform 2 is reduced. When the user needs to change the gradient of the treadmill 2 to change the amount of exercise, the adjustment is made by the legs 52 of the support frame 5. When the treadmill needs to be folded or carried, the support frame 5 can be folded, the support rods 12 at the holding ends are rotated, and the support rods 12 and the support frame 5 are folded to be parallel to the running platform 2, so that the space volume of the treadmill is reduced.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive various changes or substitutions within the technical scope of the present invention, and these should be covered by the scope of the present invention.
