Generating deceleration strip adopting piezoelectric material
The invention discloses a generating deceleration strip adopting a piezoelectric material. The deceleration strip is provided with a plurality of identical generating units; cross-shaped grooves are formed in lower bases of the generating units; the lower bases are fixedly connected with the lower ends of upper bases; circular-arc top bases and center grooves in the upper bases construct sliding pairs; one end of each variable-pitch worm extends into center countersinks of the cross-shaped grooves, and the other ends of the variable-pitch worms are connected with bearings which are embedded into the centers of the circular-arc top bases; the circular-arc upper bases are connected with circular-arc upper bases by using springs; four worm wheels provided with offset pins are symmetrically arranged on the bottom surfaces of the cross-shaped grooves in the lower bases and construct worm wheel pairs with the variable-pitch screws; one end of each connecting rod is connected with the offset pins of respective worm, and the other end of each connecting rod is connected with a slide block lug in respective movable pressure plate assembly; each slide block and the respective cross-shaped groove construct a sliding pair; piezoelectric crystals are arranged on the tops of the cross-shaped grooves. A sliding pressure plate is driven to extrude the piezoelectric crystals through the connecting rods to generate power, so that energy lost when vehicles pass can be utilized fully, and relatively stable current is generated.
