This paper introduces a kind of load-bearing device that can realize energy recovery, which has the function of continuous power generation and can enhance the power continuation capacity of outdoor sports personnel communication equipment. The device uses the fluctuation of the center of gravity when the human body is walking to convert the relative linear motion between the load and the human body into the single-direction rotation motion of the motor, so as to achieve the function of generating electricity and realize the power supply of the portable equipment through the power electronic circuit. First establish the mathematical model of the backpack, and then verify the power generation efficiency of the backpack through simulation and experiment.
