Abstract

The invention discloses a reconfigurable wheel leg combination type wheelchair. The wheelchair adopts a modular design and is characterized by comprising front leg mechanisms, front leg adjusting mechanisms, a front leg power transmission mechanism, an adjustable pedal plate, a wheelchair rack, a seat adjusting mechanism, a stair climbing mechanism, a seat, a safety belt, driving wheels, universal wheels and a controller, wherein the wheelchair rack is a central member connecting all mechanisms of the wheelchair, two groups of front leg adjusting mechanisms are symmetrically installed on a front end suspending arm of the wheelchair rack and are connected with the front leg power transmission mechanism, the front leg power transmission mechanism is arranged on the front portion inside the wheelchair rack, the seat adjusting mechanism is hinged with an outer slide way on the upper portion of the wheelchair rack through four connecting rods, the seat is fixed on the seat adjusting mechanism, a handle controller is installed on a seat armrest and connected with the controller, the stair climbing mechanism is installed at the bottom of the rear end of the wheelchair rack, two driving wheels are installed on two sides of the middle portion of the wheelchair rack respectively, and two universal wheels are symmetrically fixed on a rear suspending arm of the wheelchair rack.

Description

technical field [0001] The invention relates to a wheelchair technology, in particular to a reconfigurable wheel-leg composite wheelchair. Background technique [0002] Electric wheelchairs (or wheelchair vehicles) can facilitate the walking of the elderly and those with disabilities of the lower limbs. However, ordinary wheelchairs are only suitable for walking on flat ground or slopes, and do not have the function of climbing stairs and surmounting obstacles. However, steps, stairs or ridges are often encountered in the living environment, which greatly limits the scope of use of electric wheelchairs. So people began to study electric wheelchairs with functions such as climbing stairs. The "running multi-purpose wheelchair" of designs such as Dong Shangbin discloses a kind of electric or manual, multi-purpose wheelchair (referring to ZL86210653) that can run on level ground and use up and down stairs. Its main technical content is that the front and rear rollers on the s...
