[0002] With the improvement of people's living standards and the promotion of national fitness activities, users have an increasing demand for treadmills. Treadmills are suitable for indoor use, take up little space, and are loved by many users.

[0003] CN118477285A discloses a one-piece molded treadmill structure, including an outer contour that is U-shaped and integrally molded. A drive mechanism is fixedly located at one end of the curved outer contour, and a running mechanism is rotatably located at the end of the outer contour near the drive mechanism. The running mechanism and drive mechanism are connected by a transmission. A support mechanism is fixedly located at the bottom end of the outer contour.
