Abstract (en)

A wheelchair including a main frame (1), two main wheels (2), a caster (32) and an assistive driving system (3) is disclosed. The two main wheels (2) are coaxially mounted to two sides of the main frame (1), respectively. A first reference plane (S1) passes through a center of each of the two main wheels (2). The first reference plane (S1) is parallel to the ground. The assistive driving system (3) includes a slanted bar (31) connected to the caster (32) and the main frame (1). The slanted bar (31) has a force-exerting point (P) with respect to the main frame (1). The force-exerting point (P) is located on the first reference plane (S1). The caster (32) is relatively adjacent to a rear end of the main frame (1) than the force-exerting point (P) is.
