Abstract:
1. A cushioning mechanism of a treadmill, comprising: the treadmill including: wherein the cushioning mechanism includes two hanging support pieces, two hanging swing pieces, and a flexible elastic element, wherein the hanging support pieces each have one end pivotably coupled to the auxiliary plate and the other end pivotably connected to the hanging swing pieces, wherein the hanging swing pieces are pivotably coupled in a hanging way to the base frame with the bottom end thereof pivotably connected to the flexible elastic element, and wherein both sides of the flexible elastic element are connected to the hanging swing pieces, respectively, whereby, when the running board is subject to a downward force and sinks, the flexible elastic element mounted below will be pulled and expanded externally, and the expansion displacement of the flexible elastic element will be compensated by the swing effect of the hanging support pieces and the hanging swing pieces, and when the external force is eliminated, the running board will be returned back to its original position by the self-restoring ability of the flexible elastic element such that an expected and optimal cushioning effect is achieved.
