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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an exercising machine and more specifically, to a power generating structure of an exerciser.[0003]2. Description of the Related Art[0004]A wheeled exerciser, for example, a stationary bicycle, as shown in FIGS. 1 and 2, comprises a frame structure 1, a crank and pedal assembly 2, a driving wheel 3, two transmission belts 4, a transmission shaft 5, a transmission wheel 6, a monitor 7, a gravity wheel 8, a reluctance generator 9. When pedaling the crank and pedal assembly 2 to rotate the driving wheel 3, the transmission shaft 5 is rotated by one transmission belt 4, and the transmission wheel 6 is rotated with the transmission shaft 5 to rotate the gravity wheel 8 and the reluctance generator 9 via the other transmission belt 4, thereby causing the reluctance generator 9 to generate electricity for the monitor 7.[0005]The power generating system of the aforesaid design has numerous drawb...

Benefits of technology

[0010]The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a power generating structure of an exerciser, which is easy and inexpensive to install. It is another object of the present invention to provide a power generating structure of an exerciser, which is stable and durable in use. To achieve these and other objects of the present invention, the power generating structure is installed in a wheeled exerciser, for example, a stationary bicycle, comprising 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.

Problems solved by technology

1. The system uses the driving wheel 3, the transmission belts 4, the transmission shaft 5, and the transmission wheel 6 to transfer applied force from the user to the gravity wheel 8 and the reluctance generator 9. This transmission arrangement uses a number of parts, resulting in a complicated structure and high cost.

2. Because the system uses a number of wheels (the driving wheel 3, the transmission wheel 6, and the gravity wheel 8) to transfer applied force from the user to the reluctance generator 9, it requires much effort to drive the reluctance generator 9 to generate electricity.

3. The reluctance generator 9 is heavy and expensive, and requires much installation space.

4. The gravity wheel 8 is a metal wheel that becomes hot quietly during operation of the exerciser, and the transmission belt 4 that is coupled to the gravity wheel 8 will become loosened soon when the gravity wheel 8 is hot, thereby affecting transmission of the applied force to the reluctance generator 9.
