Title:
RESISTANCE ADJUSTMENT DEVICE, RESISTANCE-ADJUSTABLE ROTATING WHEEL AND SPORTS APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/284757
Kind Code:
A1
Abstract:
A resistance adjustment device, a resistance-adjustable rotating wheel and a sports apparatus. A first magnetic tile (110) and a second magnetic tile (120) of the resistance adjustment device (100) have magnetic surfaces (101). A rotating member (130) is rotatably mounted on a base plate (140). Two ends of a first linkage member (150) are respectively movably connected to an upper portion of the first magnetic tile (110) and an upper portion of the rotating member (130). A lower portion of the first magnetic tile (110) is rotatably connected to the base plate (140). Two ends of a second linkage member (160) are respectively connected to a lower portion of the second magnetic tile (120) and a lower portion of the rotating member (130). An upper portion of the second magnetic tile (120) is rotatably connected to the base plate (140), and the first magnetic tile (110) and the second magnetic tile (120) are held on two sides of the rotating member (130) and are spaced apart from each other. When the rotating member (130) is driven to rotate relative to the base plate (140), the rotating member (130) drives the first linkage member (150) and the second linkage member (160) to move, which in turn drives the first magnetic tile (110) and the second magnetic tile (120) to move relative to each other.
