Abstract
Description
Technical Field
[0001] The utility model relates to the field of sports equipment, in particular to a magnetic resistance brake mechanism of sports equipment. Background Art
[0002] Sports equipment is a general term for the various instruments, equipment, and supplies used in competitive sports and fitness exercises. Sports equipment and sports are interdependent and mutually reinforcing. With rising living standards, people are paying more attention to their health and therefore use fitness equipment to maintain their health. Stair climbers, also known as climbers or stair climbers, are unique among fitness equipment. They offer several times more exercise than treadmills, combining running and jumping, while also countering the Earth's magnetic field. Just five minutes a day is enough to achieve a full day's worth of exercise. Existing stair climbers operate via a motor. When not in use, the motor stops, causing the stair treads to abruptly stop. This can cause the user to lose their balance and fall forward, leading to a sudden drop. Therefore, the use of magnetic resistance brakes can effectively address this issue, preventing falls.
