Abstract

A magnetic coupling device includes a magnetic flywheel unit including a flywheel and multiple first magnets equiangularly spaced around the periphery of the flywheel to form a first annular magnetic series with the same pole facing toward the radial outer side of the flywheel, and a magnetic coupling unit including a plate body rotatably mounted to the periphery of the flywheel, a rotating shaft mounted to the center of axis of the plate body, multiple second magnets and third magnets alternatively mounted on the plate body around the rotating shaft to create a second annular magnetic series that is magnetically coupled to the first annular magnetic series. Further, a magnetoresistive ring frame is mounted to the periphery of the flywheel for movement along the axial direction of the flywheel to create a magnetic coupling control device.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application is a continuation of U.S. patent application Ser. No. 15 / 858,235, filed Dec. 29, 2017.BACKGROUND OF THE INVENTION1. Field of the Invention

[0002] The present invention relates to magnetic coupling technology and more particularly, to a magnetic coupling control device and a magnetic coupling device.2. Description of the Related Art

[0003] Magneto-resistance device used in general fitness equipment (such as flywheel) is that a magnetic control unit is pivotably arranged on the outer edge or the inner edge of the flywheel. By adjusting the distance between the magnetic control unit and the flywheel, the resistance caused by the magnetic control unit on the flywheel is relatively adjusted. Taiwan Patent M512421 teaches installation of a pivoting member in an inner edge of a flywheel and mounting of a magnet on the pivoting member so that the magnetic resistance force can be adjusted by means of adjusting the distance between the ...
