Piezoelectric power apparatus

A piezoelectric power apparatus comprising:

• a first case having a bottom surface and at least one hollow chamber recessed into the bottom surface;
• at least one piezoelectric module disposed in the hollow chamber, wherein the piezoelectric module comprises:
• at least one frame body,
• a moving member comprising a first rod and a second rod coupled to the first rod and
• a plurality of piezoelectric portions, wherein the second rod of the moving member is penetrated into the frame body, and wherein each of the piezoelectric portions comprises a first end and a second end, wherein each of the first ends is fixed at the frame body, and wherein each of the second ends is fixed at the second rod of the moving member, and wherein the second rod of the moving member is moved back and forth in the frame body;
• and
• a rotating member having a crank rod and an empennage, wherein the crank rod comprises a rod and a plurality of cranks protruded from the rod, the empennage is disposed at another end of the rod, wherein one end of the first rod of the moving member is pivotally disposed at the crank of the rotating member and wherein the first rod of the moving member is driven by the rotating member and wherein the plurality of piezoelectric portions are driven by the second rod,
• wherein the rod comprises a center line, and a gap is formed between each of the cranks and the center line.
