US 12,741,179 B2 · Mode switching system and exercise bike comprising the same

Abstract

Disclosed herein are a mode switching system and an exercise bike comprising the same that switches a non-freewheel mode and a freewheel mode automatically, ensuring improvement in user convenience. The exercise bike comprise a step motor, a first limit sensor sensing a first part of the face gear and outputting a first sensing signal, a second limit sensor sensing a second part of the face gear and outputting a second sensing signal, and a controller determining a current power transfer mode by using the first sensing signal and the second sensing signal, and rotating the step motor forward or reversely, based on the current power transfer mode, to switch the power transfer mode to the non-freewheel mode or the freewheel mode, in a case where a mode switching signal is input.

Dependent claims

A mode switching system, comprising;

a step motor fastening a face gear of an exercise bike to a wheel-face gear or separating the face gear from the wheel-face gear, based on a driving signal, to switch a power transfer mode to a non-freewheel mode or a freewheel mode;
a first limit sensor sensing a first part of the face gear and outputting a first sensing signal;
a second limit sensor sensing a second part of the face gear and outputting a second sensing signal;
and
a controller determining the power transfer mode of a current state by using the first sensing signal and the second sensing signal, and rotating the step motor forward or reverse, based on the power transfer mode of the current state, to switch the power transfer mode to the non-freewheel mode or the freewheel mode, in a case where a mode switching signal is input.
