Abstract
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.
