Abstract
A shoe energy collecting device includes a shell, a piezoelectric assembly, an elastic component, a magnet array, a base, a supporting block, an upper friction assembly and a lower friction assembly. The shell includes a supporting shell and a plastic shell connected in sequence. The base is provided below the supporting block in the supporting shell, the lower friction assembly is provided between the supporting block and the base. The upper friction assembly is provided on an inner wall of a top surface of the plastic shell. A coil is provided on a lower surface of the lower friction assembly at a side of the plastic shell, and the magnet array is provided below the coil. The piezoelectric assembly is provided in the plastic shell, the elastic component is provided on a side wall of the plastic shell away from the supporting block, and connected with the piezoelectric assembly.
