The invention discloses a piezoelectric power generation mechanical elastic wheel, and relates to the technical field of energy recovery. Vibration generated by tires during vehicle running can be converted into electric energy through the piezoelectric effect, and waste energy recycling is achieved. The mechanical elastic wheel comprises a framework and a rubber tread installed on the outer ring of the framework. The elastic ring and the clamping ring are wrapped by the rubber tread, the rubber tread is divided into an inner side rubber ring and an outer side rubber ring by the elastic ring, a sheet-shaped piezoelectric film is arranged between the elastic ring and the outer side rubber ring, one end of the piezoelectric film is connected with two wires, one end of each wire is fixed to the piezoelectric film through a film patch, and the other end of each wire is fixed to the rubber tread. And the other end is connected to a component needing energy supply. The energy consumption during vehicle running is reduced to a certain extent, and the energy utilization efficiency is improved.
