Patent Description:
A running platform of a treadmill is designed with a slope to increase the exercise amount and exercise intensity of a user, and the exercise amount and exercise intensity of the user can be effectively adjusted by adjusting the slope of the running platform, so that the user can adjust the exercise amount and exercise intensity as required. However, a traditional treadmill driven by a motor often consumes a large amount of electricity, generates loud noise and has high cost. The speed of driving the movement is low in a case that other modes are used for driving. In a case that a longer stroke is required for adjustment, longer time is often required, which is difficult to meet the requirement of rapid adjustment by the user.

Document <CIT>discloses a treadmill according to the preamble of claim <NUM>.

Based on this, it is necessary to provide a treadmill to solve at least one of the above problems.

The supporting foot includes two first plate bodies and a second plate body located between the two first plate bodies, and two ends of the second plate body are connected to the two first plate bodies, respectively. The two first borders and the second border are located above the two first plate bodies and the second plate body. The running platform further a first guide structure, the first guide structure is arranged at the second border and the first guide structure is a sliding groove, the driving piece is arranged at the second border; a lower end of the supporting piece is rotatably connected to the second plate body; an upper end of the supporting piece is slidably connected to the second border; the upper end of the supporting piece is slidably arranged at the sliding groove; the driving piece is configured to drive the upper end of the supporting piece to translate along the sliding groove such that the lower end of the supporting piece rotates around the upper end of the supporting piece, and the lower end of the supporting piece pushes the supporting foot to move towards or away from the border.

Further, the driving piece includes a first connecting end and a second connecting end, the first connecting end is a hinge, the second border is provided with a first shaft hole at a position corresponding to the first connecting end, and the first connecting end is hinged to the first shaft hole of the second border; the second connecting end is a lug, the lug is provided with a second shaft hole at a position corresponding to the supporting piece, the supporting piece is provided with a third shaft hole at a position corresponding to the second shaft hole of the lug, a shaft penetrates into the second shaft hole of the lug and the third shaft hole of the supporting piece to rotatably connect the supporting piece to the driving piece.

Further, the running platform further includes a second guide structure, the second guide structure is a U-shaped groove and is arranged at the second border, and the second guide structure is configured to guide a movement of the second connecting end relative to the first connecting end.

Further, the second plate body is provided with a second connecting piece at a position corresponding to the supporting piece, and the lower end of the supporting piece is hinged to the second plate body.

According to the above treadmill, a shorter translation stroke of the driving piece is converted into a longer rotating stroke of one end of the supporting piece through the supporting piece. Therefore, a stroke of the driving piece driving the running platform to move up and down can be enlarged, so that in a case that a longer stroke is required for adjustment, in-place adjustment can be achieved within a short time, and the requirement of rapid adjustment by a user can be met while energy consumption, noise and cost are reduced.
