It should be noted that the inventive concept of the present disclosure can also be extended to exercise and fitness equipment such as walking machines and treadmills.

In some embodiments of the present disclosure, the first driving mechanism may be connected to the front running board assembly 100 for driving the front running board assembly 100 to rotate relative to the middle running board assembly 200 so as to realize the front running board assembly 100 and the middle running board assembly 200, at the same time, because the rear running board assembly 300 and the middle running board assembly 200 are connected in a hinged form, combined with the setting of the intermodal mechanism, therefore, the rear running board assembly 300 and the middle running board assembly 200 can also be realized. Synchronous folding, so as to realize the three-stage automatic folding of the treadmill, and optimize the space saving.

In other disclosed embodiments, the first driving mechanism may also be connected to the rear running board assembly 300 for driving the rear running board assembly 300 to rotate relative to the middle running board assembly 200 so as to achieve the rear running board assembly 300 and the middle running board assembly. The folding of the assembly 200, at the same time, because the front running board assembly 100 and the middle running board assembly 200 are hingedly connected, and combined with the setting of the intermodal mechanism, the front running board assembly 100 and the middle running board assembly 200 can also be synchronized Folding, the three-stage automatic folding of the treadmill can also be realized.

Optionally, in the folded position, the angle formed between the front running board assembly 100 and the middle running board assembly 200 and/or between the rear running board assembly 300 and the middle running board assembly 200 is 90°. That is, in some embodiments, when the front running board assembly 100 and the rear running board assembly 300 are rotated 90° toward the bottom surface of the middle running board assembly 200, the front running board assembly 100 and the rear running board assembly 300 are both in the middle. The vertical position of the running board assembly 200 realizes the folding of the folding treadmill. The current running board assembly 100 and the rear running board assembly 300 are rotated toward the bottom surface away from the middle running board assembly 200 to the front running board assembly 100 and the rear running board assembly 300. When the upper surfaces are coplanar with the upper surface of the middle running board assembly 200, that is, the three are in the same horizontal plane, the folding treadmill can be unfolded.

The first drive mechanism can be configured in any manner, as shown in Figures 1 and 2, in some embodiments of the present disclosure, the first drive mechanism is configured as a linear drive unit 410, a strut 420 and a first roller 430; wherein , the linear drive unit 410 includes but is not limited to an electric push rod, a linear module or a drive cylinder, and the drive cylinder may be a hydraulic cylinder, an air cylinder, or an electric cylinder.
