Power generator, suspension, vehicle, apparatus for producing power generator, and method for producing power generator

An apparatus for producing a power generator, comprising:

• a providing device, for providing a cylinder body, a moving member, and a piezoelectric conversion unit;
• and
• an installing device, for installing the cylinder body, the moving member, and the piezoelectric conversion unit, to make the piezoelectric conversion unit be located in a variable cavity jointly defined by the moving member and the cylinder body, wherein the piezoelectric conversion unit is configured to deform when the moving member is in relative motion with respect to the cylinder body and changes the size of the variable cavity, for generating electric energy.

A method for producing a power generator, comprising:

• providing a cylinder body, a moving member, and a piezoelectric conversion unit;
• installing the cylinder body, the moving member, and the piezoelectric conversion unit together, to make the piezoelectric conversion unit be located in a variable cavity jointly defined by the moving member and the cylinder body, wherein the piezoelectric conversion unit is configured to deform when the moving member is in relative motion with respect to the cylinder body and changes the size of the variable cavity, for generating electric energy.
