This invention relates to an electric wheelchair which integrates sitting, standing, and reclining, which comprises: a back part, a support stepping part, a base, a seat part, and a coupling component. The base has a track part, a sliding part, and a lifting mechanism. Accordingly, when the lifting mechanism is located at an extending position, the back part, the support stepping part, and the seat part, which are pivotally coupled to each other, are in a reclining status. When the lifting mechanism is located in a middle section position, the back part, the support stepping part, and the seat part, which are pivotally coupled to each other, are in a sitting status. When the lifting mechanism is located at a contraction position, the back part, the support stepping part, and the seat part, which are pivotally coupled to each other, are in a standing expansion status. Therefore, this invention has the advantages and efficacies of simple operation, good stability, reclining relaxation, blood circulation promotion, and lower cost.本發明係為一種整合坐、站、後傾之電動輪椅,其包括:一背部、一支撐踏部、一底座、一坐部及一連動組件。該底座設一軌道部、一滑動部及一升降機構;藉此,當該升降機構位於一延伸位置時,相互樞接連動之背部、該支撐踏部及該坐部係呈後傾狀態;當該升降機構位於一中段位置時,相互樞接連動之背部、該支撐踏部及該坐部係呈座椅狀態;而當該升降機構位於一收縮位置時,相互樞接連動之背部、該支撐踏部及該坐部係呈直立之展開狀態;故,本發明兼具操作簡單、穩定性佳、後傾舒壓、促進血液循環及成本較低等優點及功效。10‧‧‧背部11‧‧‧背部連接部11A‧‧‧上端11B‧‧‧下端112‧‧‧延伸桿112A‧‧‧延伸樞接部20‧‧‧支撐踏部21‧‧‧支撐踏部樞轉端22‧‧‧踏部連接端23‧‧‧踏部30‧‧‧底座31‧‧‧支架部31A‧‧‧前端31B‧‧‧後端311‧‧‧第一支架樞接部321‧‧‧活動輪33‧‧‧軌道部34‧‧‧滑動部341‧‧‧第一滑動樞接部342‧‧‧第二滑動樞接部343‧‧‧連接部35‧‧‧升降機構351‧‧‧升降元件40‧‧‧坐部41‧‧‧連動樞接部51‧‧‧第一連桿52‧‧‧第二連桿53‧‧‧限制桿
