Abstract

A shaking mechanism of a treadmill having a shaking plate attached to the bottom of a platform of the treadmill. The shaking plate is driven by at least one shaking drive unit disposed on a supporting plate of a base frame such that the platform creates an expected up-and-down shaking effect.

Claims

1. A shaking mechanism of a treadmill having a transmission motor at one side of a base frame thereof in cooperation with a transmission belt, a front roller and a rear roller for rotating a continuous moving belt around a platform,

wherein a shaking plate is attached via a connecting piece to the bottom of the platform of the electric treadmill, and the shaking plate is driven by at least one shaking drive unit disposed on a supporting plate of the base frame such that the platform creates an expected up-and-down shaking effect.

2. The shaking mechanism of a treadmill as claimed in claim 1, wherein the shaking drive unit includes more than one set of permanent magnets (that is fixed at the bottom of the shaking plate) and electromagnets (that are disposed at the end of the supporting plate) corresponding to the permanent magnets in quantity as well as in position.

3. The shaking mechanism of a treadmill as claimed in claim 1, wherein the shaking drive unit can be replaced by an electric motor in cooperation with more than one cam mechanism.
