Piezoelectric ceramic conversion device capable of controlling deformation of piezoelectric ceramic piece and manufacturing method thereof

Abstract

The invention discloses a piezoelectric ceramic conversion device capable of controlling deformation of a piezoelectric ceramic piece. The device comprises a pressing plate, a metal frame and a packaging box, wherein the pressing plate is mounted in a pavement mounting groove; the pressing plate is provided with an elastic return mechanism; the internal space of the packaging box is transversely divided into three compartments, wherein a circuit board is placed in middle compartment, a plurality of pairs of clamping devices for fixing piezoelectric ceramic pieces are arranged on the side plates of the compartments at the two sides; a piezoelectric ceramic piece is clamped and transversely fixed by each pair of clamping devices; the upper end of the metal frame is fixed to the pressing plate, and the lower end of the metal frame downwards penetrates through a soil body to press all the piezoelectric ceramic pieces; all the piezoelectric ceramic pieces are connected with the circuit board installed in the middle compartment; and the pressing plate is pressed to settle in the pavement mounting groove, and then the piezoelectric ceramic pieces are pushed downwards. The invention further discloses a manufacturing method of the piezoelectric ceramic conversion device capable of controlling deformation of the piezoelectric ceramic piece. The piezoelectric ceramic conversion device ismore stable in structure, more sufficient in vehicle load transmission and larger in piezoelectric ceramic piece deformation, so that the electric energy collection amount is larger.
