Power generating structure of an exerciser

Abstract

A power generating structure of an exerciser is disclosed to include a driving wheel, a crank and pedal assembly for pedaling by the user to rotate the driving wheel, a gravity wheel, a first transmission belt coupled between the driving wheel and the gravity wheel, a big idle wheel fixedly provided at one side of the gravity wheel, a power generator, a small idle wheel provided at one side of the power generator, and a second transmission belt coupled between the big idle wheel and the small idle wheel for driving the power generator to generate electricity upon rotation of the gravity wheel by the driving wheel.

1 . A power generating structure of an exerciser comprising a driving wheel, a crank and a pedal assembly fastened to said driving wheel for pedaling by the user to rotate said driving wheel, a gravity wheel having a gravity wheel diameter, a transmission belt coupled between said driving wheel and said gravity wheel, and a generator rotatable by said gravity wheel to generate electricity, wherein said gravity wheel has a big idle wheel fixedly fastened to one side thereof for synchronous rotation; said big idle wheel having a diameter less than said gravity wheel diameter, a controller in electrical cooperation with said big idle wheel for adjusting the resistance of the gravity wheel subjecting to different exercise requirements; said power generator has a small idle wheel fixedly fastened to one side thereof and coupled to said big idle wheel by a transmission belt for driving said power generator to generate electricity upon rotation of said gravity wheel, and an electricity accumulator electrically connected to a power output end thereof for storing generated electricity.
