The present invention discloses a Multi-Functional Wheelchair, which includes base frame, seat frame, elevation actuating mechanism and control mechanism. The base frame is mounted with front and rear wheels. The elevation actuating mechanism includes linear retractable actuator and two sets of toggle linkage assembly. Two ends of each toggle linkage assembly pivotally connect to the base frame and seat frame respectively. Two ends of the actuator pivotally connect to the junctions of the two toggle linkage assembly. Whereby, the seat frame can be adjusted the inclination and height with respect to the base frame by the elevation actuating mechanism and the control mechanism.本發明係有關於一種多功能輪椅,其包括底架、座架、升降致動機構及控制機構。底架上設有前輪及後輪。升降致動機構包括線性伸縮致動器、二個相對應的肘節連桿組。每一肘節連桿組兩端分別樞接底架及座架。線性伸縮致動器兩端分別樞接二肘節連桿組的肘關節。藉由升降致動機構及控制機構,以使座架可相對底架升降及傾斜角度,而達到多功能之目的。10‧‧‧底架11‧‧‧前輪12‧‧‧後輪20‧‧‧座架21‧‧‧座墊22‧‧‧靠架23‧‧‧扶手24‧‧‧導柱25‧‧‧開孔26‧‧‧蓋板30‧‧‧升降致動機構31‧‧‧線性伸縮致動器32/33‧‧‧肘節連桿組40‧‧‧控制機構41‧‧‧導軌43‧‧‧定位座45‧‧‧框架
