A power auxiliary device comprises a thigh fastener, a sole fastener, a gas storage bottle, a control valve, a pneumatic cylinder, a control unit, and at least a sole pressure sensor and a position trigger sensor wherein, the pneumatic cylinder is connected with the sole fastener and the thigh fastener the sole pressure sensor is used to detect a sole stepping pressure when the thigh fastener is approaching relative to the sole fastener, the pneumatic cylinder is compressed to make the gas storage bottle storing energy, and when the position trigger sensor is triggered, the control unit controls the control valve to close the gas storage bottle and, when the thigh fastener is moving away relative to the sole fastener and the overall sole stepping pressure sensed by the sole pressure sensor exceeds a predetermined pressure, the control unit controls the control valve to open the gas storage bottle and release energy, so as to form the push force moving up the thigh fastener.一種動力輔助裝置,包含一大腿固定件、一腳底固定件、一儲氣瓶、一控制閥、一氣壓缸、一控制單元、至少一腳底壓力感測器及一位置觸發感測器。氣壓缸連接於腳底固定件及大腿固定件;腳底壓力感測器用以感測一腳底踩踏壓力,當大腿固定件相對於腳底固定件靠近,氣壓缸被壓縮而使儲氣瓶儲存能量,且當位置觸發感測器被觸發時,控制單元控制控制閥將儲氣瓶關閉,當大腿固定件相對於腳底固定件遠離,且於腳底壓力感測器所感測的腳底踩踏壓力總合超過一預設壓力時,控制單元控制控制閥將儲氣瓶開啟而釋放能量,以形成使大腿固定件往上之推力。100...動力輔助裝置1...大腿固定件2...小腿固定件3...腳底固定件31...腳跟底座32...連接件4...儲氣瓶40...控制閥5...氣壓缸6...角度量測單元61...上固定板組62...下固定板組63...蓋體8...位置觸發感測器10...塑膠管
