Abstract
A wheelchair including a seat body and at least one wheel module disposed at a bottom of the seat body is provided. The wheel module includes a motor, at least one wheel, and a transmission unit coupled between the motor and the wheel. The transmission unit has at least one one-way bearing. The motor outputs a first rotating moment and a second rotating moment with opposite directions to the transmission unit. The one-way bearing transmits one of the first rotating moment and the second rotating moment to the wheel to drive the wheel to roll, such that the seat body is in linear motion, or so the wheel module rotates relative to the seat body in the directions of the first or the second rotating moments. The shafts of the first and the second rotating moments are perpendicular to the rotating shaft of the wheel.
