Abstract

L'invention concerne un fauteuil roulant multifonction, comprenant un siège de fauteuil roulant (1) et deux ensembles de roues (2). Les deux ensembles de roues (2) sont respectivement disposés en rotation sur deux côtés d'une partie inférieure du siège de fauteuil roulant (1). Chaque ensemble de roues (2) comprend une grande roue (21). Une pluralité de pneus de roue (211) est disposée de manière fixe le long de la circonférence de la grande roue (21). Une rainure (2111) est disposée entre chacun des pneus des roues (211). Une planche à aubes (212) est disposée de manière fixe dans chacune des rainures (2111). La longueur de chacune des planches à aubes (212) le long du rayon de la grande roue (21) est inférieure à la longueur du pneu de roue (211) le long du rayon de la grande roue (21). Lorsque la grande roue (21) tourne le long d'une surface de sol, aucune des planches à aubes (212) n'entre en contact avec la surface du sol. La planche à aubes (212) du fauteuil roulant multifonction n'interfère pas avec le mouvement sur la route. Dans l'eau, la planche à aubes (212) entre perpendiculairement en contact avec un écoulement d'eau et peut empêcher l'écoulement d'eau, réduire la résistance à l'eau et aider à la décharge d'eau, et une force de réaction peut améliorer le mouvement du fauteuil roulant.
