Electric wheelchair stairs-climbing vehicle

Abstract: The utility model discloses an electric stair climbing machine for a wheel chair. A wheel chair fixing rod is arranged on the back end of a machine frame, and a wheel chair supporting plate is arranged on the machine frame through a supporting frame; and two pairs of crawler wheels are arranged on the inner sides of the front end and the back end of the machine frame respectively, the two pairs of the crawler wheels arranged on the front end of the machine frame are fixed on two ends of a low speed shaft and are arranged on the machine frame through the low speed shaft, a gearwheel is arranged on the low speed shaft and is engaged with a pinion which is arranged on an output shaft of an engine, a guide plate for guiding the wheel chair to move up and down is arranged on the front end of the supporting plate in a folding mode, and the back end of the supporting plate is provided with a baffle plate. Two pairs of assistant wheels are arranged on the outer side of the machine frame and are positioned between the two pairs of the crawler wheels. The electric stair climbing machine for the wheel chair is provided with the guide plate, so that a person sitting on the wheel chair can get on and get off the stair climbing machine along the guide plate smoothly and lightly to save labor power without the help from others. The stair climbing machine not only can climb a stair, but also can run freely on a flat road by applying little propulsion through the assistant wheels.
