Piezoelectric electromagnetic hybrid exoskeleton energy harvesting device

The utility model belongs to the technical field of power generation, and particularly relates to a piezoelectric electromagnetic hybrid exoskeleton energy harvesting device. Comprising a frame composed of two frame connecting plates and mounting blocks located at the two ends and used for connecting the two frame connecting plates. Fixed magnets are arranged on the outer sides of the mounting blocks, piezoelectric cantilever beams are arranged on the upper sides or the lower sides of the two mounting blocks, fixed magnets are arranged at the tail ends of the two piezoelectric cantilever beams, and the four fixed magnets are distributed in a cross shape and coupled to form a fixed magnetic field. The sleeve is in interference fit with the two ends of the mounting block and arranged in the frame, the movable magnet is suspended in the middle of the interior of the sleeve, the fixed magnets at the two ends of the mounting block are arranged in a homopolar repulsion mode, and the sleeve is sleeved with a coil.
