摘要：NOVELTY - This new utility model relates to one kind novel wheelchair capable of climbing stairs, mainly comprising to crawler mechanism, speed reducing mechanism, a lifting mechanism, a driving parameter structure design and strength checking is given. Adopt wheel-crawler mechanism mix, a wheel mechanism for flat, back wheel hub motor driving wheel, front and rear crawler mechanism for upper lower, front crawler drive mechanism, front and rear crawler common support. Respectively using planet wheel and worm wheel worm two grade speed reducing device, motor pushing mechanism stretch and shrink, using wheel away from the floor. This utility model new combination of crawler-type wheelchair operation efficiency, stable movement and wheel group type wheelchair running retardant force small, flexible movement and it overcomes of other type wheelchair center of gravity fluctuation large, slow action, device type large, complex operation equal defect.
