When human body carries this device, swing arm 4 is fixed on shank or forearm, supporting base 1 is fixed in thigh or large arm, when human body walking, swing arm 4 is along with the swing of shank or forearm and swing, thus driving wobble gear 2, wobble gear 2 moves slide tooth bar 5 by the cingulum of engagement and reciprocatingly slides on slideway 6, and meanwhile slide tooth bar 5 drives input gear 7 reciprocating rotation again.Input gear 7 reciprocating rotation, through the transmission of non-return device 9, the rotor being converted to generator 11 only rotates along the direction of a setting, thus drive electrical generators 11 generates electricity, and completes the conversion of mechanical energy to electric energy of human body.The electric energy that generator 11 produces can be stored in electric accumulator for subsequent use after rectifying and voltage-stabilizing, also directly can power to various electronic equipment.

beneficial effect:

1, the utility model utilizes meshed gears that the swing of limbs during human body walking is converted to the rotation of motor, and then changes mechanical energy is become electric energy, can be good at the defect alleviating existing mobile electronic device electricity shortage, achieve the possibility obtaining electricity whenever and wherever possible.

2, the utility model is, according to the feature of the limb motion of people, the changes mechanical energy of surplus during human body walking is become electric energy, does not relate to outside resources consumption, and environmental conditions restriction is little, energy-conserving and environment-protective.

3, the utility model compact structure, is convenient to outdoor exercises person or outwork person carries with.
