Title:
PULLING FORCE STEPLESS REGULATION COUNTERWEIGHT POWER GENERATION MECHANISM AND FITNESS APPARATUS HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2023/010595
Kind Code:
A1
Abstract:
A pulling force stepless regulation counterweight power generation mechanism and a fitness apparatus having same. The mechanism comprises a pulling rope (1), a winding drum (2), a mounting base, a central shaft (4), a spring (6), a power generator (11), and a regulator (13); one end of the pulling rope (1) is connected to the winding drum (2), and a part of the pulling rope (1) is wound on the peripheral wall of the winding drum (2); the winding drum (2) is rotatably connected to the mounting base, an outer end of the spring (6) is connected to the winding drum (2), and an inner end of the spring (6) is connected to the mounting base; the central shaft (4) is rotatably provided on the mounting base, and the winding drum (2) can be externally sleeved on the central shaft (4) in a unidirectional rotating manner, so that when the pulling rope (1) drives the winding drum (2) to rotate, the central shaft (4) rotates along with the winding drum (2), and meanwhile, the spring (6) is tightened; and the central shaft (4) is connected to a motor shaft of the power generator (11), and the regulator (13) is connected to the power generator (11). According to the mechanism, a pulling process and a power generation process are organically combined together, and the regulator (13) is used for regulating rotation damping of the motor shaft of the power generator (11) to regulate a pulling force in a phase-changing manner, so that stepless regulation of the pulling force can be achieved, and chemical energy consumed by a human body in an exercise process can be converted into electric energy for use.
