Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0025] 4. A radius analysis method conforming to human body motion treadmill, it is characterized in that, comprises: Step 1: determine motion locus, set motion arc length as s, speed is t, then its speed of motion and then And =0, and its curvature k(t)=|p'(t)×p"(t)| / |p'(t)| 3 =|p″(s)|, there is no sudden change in the curvature of the motion, when a curve has a constant curvature on a certain continuous segment, the obtained curve satisfies the vector equation:

[0026]

[0027] Step 2: Determine the radius r range of the treadmill, and set the positions of human hip joints, knee joints, ankle joints, toe joints and toe tips as A 1 、A 2 、A 3 、A 4 , let l f The horizontal distance, the vertical height difference is h, and the tip of the toe is always in contact with the sport...

Abstract

The invention provides a radius analysis method of a running machine conforming to human motion and the running machine. The running machine comprises a rack, a running device and a lifting device. The lifting device comprises a left lifting belt wheel, a right lifting belt wheel and a lifting belt. The lifting belt is wound around the left lifting belt wheel and the right lifting belt wheel, andthe left lifting belt wheel and the right lifting belt wheel are in a tensioned state. The radius analysis method and the running machine have the advantages that the lifting device is additionally arranged in the structure, the lower side of a running belt of the running machine is supported, vertical suspending of the lower side is reduced, the upper side of the running belt is attached to an arc-shaped supporting rolling way, the gap is reduced, impact of the running belt to the arc-shaped supporting rolling way during motion is reduced, impact noise is lowered, and the running machine is more suitable for human motion. By means of the motion device, damage is reduced, the motion device is healthier, and the comfort is improved.

Description

technical field [0001] The invention relates to the technical field of sports equipment, and relates to a radius analysis method and a treadmill conforming to human body movement. Background technique [0002] Among fitness equipment, the treadmill is a common exercise device. Yet unpowered treadmill is a kind of treadmill with higher research and development degree at present, and this treadmill not only saves electric energy but also is convenient to be installed in places such as parks, stadiums, sports centers, and is very convenient. However, the current unpowered treadmill, the lower part of the running belt is curved downwards, resulting in a gap between the upper side of the running belt and the arc-shaped support raceway, especially during high-speed movement due to the centrifugal force, the running belt leaves the track and rolls the raceway, which is prone to impact and damage. noise. In this case, the unsafe influence brought by the noise and impact will cause...
