A wheelchair device includes a vehicle body unit, a seat unit mounted to the vehicle body unit, and a drive unit attached to the vehicle body unit and coupled to the seat unit. The seat unit can be driven by the drive unit, and the upper and lower displacements of the body unit between the ground position on the ground and the seating position above the ground position are changed. The drive unit can drive the design of the seat unit relative to the vehicle body unit between the ground position and the seating position, and the caregiver can be saved after the seat unit is lowered to the ground position. The inconvenient person is pulled to the seat body, and the person with reduced mobility can also move to the seat body and return to the normal riding state, which is a convenient and practical and innovative wheelchair device design.一種輪椅裝置，其輪椅機構包括車體單元、安裝於車體單元之椅座單元，及安裝於車體單元且連結於椅座單元之驅動單元。椅座單元能被該驅動單元驅動，而對車體單元在下移至地面上之靠地位置，及高於該靠地位置之乘坐位置間上下位移變化。透過該驅動單元可驅動該椅座單元相對該車體單元在該靠地位置與該乘坐位置間變化的設計，在控制該椅座單元下降至該靠地位置後，看護人員就可相當省力地將該行動不便者拉移至該座椅本體上，且行動不便者也能自行移動至該座椅本體上，並恢復至正常乘坐之狀態，是一種相當方便實用且創新的輪椅裝置設計。
