An electric cushioning mechanism of a treadmill having a cushioning rod assembly positioned at the rear end of the front support frame. The cushioning rod assembly is coupled to an electric cushioning mechanism. The electric cushioning mechanism includes a linking support, a cushioning drive motor, a slide element, and a slope guide plate. The linking support is provided with a roller at the bottom of both sides thereof, respectively. The cushioning drive motor has a guide screw rod. A pushing slope is formed at the bottom of both sides of the slide element. The pushing slope pushes against the slope guide plate. The roller of the linking support tends to slide on the path with different slopes by use of the angular change on the slope guide plate, thereby creating different reactive cushioning forces. |
