Nonlinear magnetic force-based arched piezoelectric ceramic energy harvesting deceleration strip

A nonlinear magnetic force-based arched piezoelectric ceramic energy harvesting deceleration strip comprising:

• an outer case and an internal generating mechanism;
• wherein the outer case structure includes an upper deceleration strip and a casing;
• the casing is embedded in a pavement structure by excavating an upper part of a surface course;
• a rebounding mechanism located between the upper deceleration strip and casing to restore a pressed upper deceleration strip;
• wherein the generating mechanism includes a rack, a gear set and generating discs;
• the rack is disposed at a bottom of the upper deceleration strip and moving up and down therewith;
• the rack engages with a first gear, the first gear and a second gear are fixed to a first transmission shaft;
• the second gear engages with a third gear to implement primary acceleration;
• the third gear and a fourth gear are fixed to a second transmission shaft;
• the fourth gear engages with a fifth gear to implement secondary acceleration;
• finally, the fifth gear drives the generating discs to rotate through a third transmission shaft;
• the first transmission shaft, second transmission shaft and third transmission shaft are rotatably connected to a vertical steel plate;
• each of the generating discs comprises a fixed outer disc and a rotary inner disc;
• an arched piezoelectric transducer is placed on the fixed outer disc;
• a first magnet is fixed to an apex of the arched piezoelectric transducer, a repellent second magnet of the same size is placed in the opposite position of the rotary inner disc;
• the arched piezoelectric transducer comprises a spring steel sheet base, an arched piezoelectric ceramic combined with the spring steel sheet base and an aluminum sheet adhering to the arched piezoelectric ceramic;
• the arched piezoelectric ceramic is fired and molded in an arched mold with preset curvature.
