Spinning magnetic control resistance adjusting device

Abstract

The invention discloses a spinning magnetic control resistance adjusting device which comprises a magnetic control flywheel used for adjusting resistance, the magnetic control flywheel comprises a metal flywheel and a magnetic control disc, the magnetic control disc and the metal flywheel form a main resistance adjusting mechanism, and the magnetic control disc driving mechanism is used for driving the magnetic control disc to move in the axial direction of a center shaft. And the supporting frame is used for supporting the central shaft so as to bear the magnetic control flywheel and the magnetic control disc driving mechanism. The conductors are arranged on the cambered surfaces of the two sides of the magnet ring, radial swing of the magnet ring is changed into axial movement, the utilization rate of magnetic lines is greatly improved, the magnetic field efficiency is improved, resistance and resistance linear change can be stably adjusted, knee joints of an exerciser are protected, a protection mechanism is additionally arranged, and the exercise effect is improved. And machine damage or injury to an exerciser caused by failure of the control system can be prevented.

Description

technical field [0001] The invention belongs to the technical field of fitness and sports equipment, and in particular relates to a magnetic control resistance adjusting device for a spinning bicycle. Background technique [0002] With the improvement of living standards, people pay more and more attention to physical health, which has spawned many fitness sports equipment, such as spinning bikes, elliptical machines, rowing machines, etc. These sports equipment usually needs to be equipped with damping devices to adapt to human exercise. Traditional damping devices are mostly magnetic control flywheel resistance adjustment devices. According to their working principle, resistance adjustment is usually achieved by adjusting the distance between the magnetic tile and the conductor on the flywheel through a complex adjustment mechanism. In the current patent documents or other related documents, the adjustment of the magnetic tile is basically a swing adjustment, that is, one ...

AI Technical Summary

Problems solved by technology

[0003] In the traditional magnetron flywheel resistance adjustment device, since the magnetic tile needs to be adjusted, the distance between the magnetic tile and the conductor on the flywheel is relatively large, resulting in a part of the magnetic field not being able to do work, which affects the efficiency of the resistance. Larger restrictions, can only be adjusted within a certain range, and cannot meet the large-scale adjustment needs of the crowd

Secondly, the traditional magnetic tile adjustment mechanism is relatively complicated, the output of the adjustment mechanism is not very stable, and there is no corresponding protection mechanism. When some devices are out of control, it is easy to cause the magnetic tile and the conductor on the flywheel to contact and damage the conductor.
