Abstract
A modularized assembly structure of a wheelchair includes two upper transverse tubes and two lower transverse tubes mounted between a pair of sided front module connecting members and a pair of sided rear module connecting members, thereby forming the main frame of the wheelchair. The front wheel and the rear wheel may be respectively mounted on the upper and lower transverse tubes which may be set at different horizontal positions and different vertical heights, so that the distance between the front wheel and the rear wheel may be adjusted arbitrarily.
