The invention discloses an energy recover device which comprises a machine body arranged at the end portion/the side portion of a rotation part and a circuit board and a rechargeable battery which arearranged in the machine body. A cantilever beam extending outwards from the end portion of the rotation part and a shell fixed at the end portion of the cantilever beam are arranged on the machine body; a sliding rail is arranged in the shell; magnets of which magnetization directions are opposite are fixed at both ends of the sliding rail; a sliding magnet which can slide along the sliding railis arranged at the middle portion of the sliding rail; repulsive forces are formed between the sliding magnet and the magnets at both end portions; positions on the shell, which are positioned at bothsides of the sliding magnet and around the sliding rail, are wound with coils; a piezoelectric ceramic is arranged at the clamping end of the cantilever beam, which is positioned at the machine body;both the piezoelectric cera
