The specific embodiment:

In Fig. 1, the bump post 1 of piezoelectric generating unit is under pressure and moves downward is to realize a bump action, piezo-electric crystal 3 is subjected to clashing into the bump of post, short time set takes place, produce the transient voltage of an about 20V, electric energy is derived through positive wire 4 and cathode conductor 5 again, compression spring 2 compressions when bump post 1 moves downward, when the pressure that bump post 1 is subjected to removes, under the reaction force of compression spring 2, recover initial position.When people's walking, this process is gone round and begun again and is realized the generating purpose.

In Fig. 2, when people's pin lands, air bag 6 is squeezed and produces a pressure, by telescopic head 7 pressure is passed to bar 8, bar 8 drives piezoelectric generating unit 12 generatings, and Fig. 3 is the transmission schematic diagram after air bag 6 is squeezed, and air bag 6 and piezoelectric generating unit 12 reset when people's less touch with the ground, this process is gone round and begun again when the people walks, two alternately generatings of footwear.

In power-generating shoe structure chart shown in Figure 4, two air bags 6 are installed in the front and rear of sole respectively, and it is continuous by conduit 9, piezoelectric generating unit 12 is installed in the sole rear portion, link to each other with two air bags 6 by conduit 11, a valve switch 10 is arranged on the conduit 11, and positive wire 4 and cathode conductor 5 are drawn through the footwear rear portion from piezoelectric generating unit 12.

In Fig. 5 overall schematic, electric storage device 14 hangs on the waist waistband, and lead 4, lead 5 and trousers 13 connect together, and there is plug at the lead two ends, is inserted in respectively on electric storage device 14 and the piezoelectric generating unit 12, and can pulls up plug at any time.

In Fig. 6 collecting circuit figure, during the piezoelectric generating unit generating, input anodal 15 and 16 voltages that produce about 20V of input negative pole, earlier through inductance 17 and electric capacity 18 filtering, after voltage-stabiliser tube 20 voltage stabilizings, voltage becomes and releives relatively again, and then gives rechargeable battery set 21 chargings.Rechargeable battery set 21 is outwards exported electric energy for use.
