A Piezoelectric Ceramic Recycling Friction Self-excited Vibration Energy

Abstract

The invention discloses a piezoelectric ceramic for recovering friction self-excited vibration energy. The piezoelectric ceramic structurally comprises a brake bottom plate, a brake shoe and a piezoelectric ceramic ring, wherein the brake shoe is mounted on the upper surface of the brake bottom plate, when an external hard force abuts against a piezoelectric ceramic body, if the force is greater than a range that a device housing can withstand, the force is collided by a soft pocket block of a balance groove of the piezoelectric ceramic ring while the piezoelectric ceramic body presses downwards, a rubber space strip acts as a barrier layer for the entirety, and plays a limiting role for the joint parts, a layer clamping angle clamped in the to-be-sandwich layer can control a force point well, an abutted part can act as a clamping position in a staggered manner, a tendency pressure bottom can obtain a buffer effect when subjected to the over-force, and when the piezoelectric ceramic issubjected to the force of parts to generate piezoelectricity, the buffer protection can be timely obtained if the force of the parts exceeds the force borne by an installation position, and the situation that the piezoelectric ceramic deforms and affects the subsequent piezoelectric is avoided.

Description

technical field [0001] The invention belongs to the field of piezoelectric materials, and more specifically relates to a piezoelectric ceramic for recovering frictional self-excited vibration energy. Background technique [0002] The current automobile brakes will generate vibration and pressure during operation. Lead zirconate titanate is installed inside, referred to as piezoelectric ceramics. The material is in a cylindrical structure, and it is squeezed according to the pressure and vibration of the brake. It generates a small piezo current to assist the operation of the brake. [0003] Based on the above-mentioned inventor's discovery, the existing recovery frictional self-excited vibration energy mainly has the following deficiencies, such as: [0004] Since the installation space of piezoelectric ceramics is relatively fixed and limited, its operation requires external pressure. During long-term force activities, the installation space will be deformed. When the piez...

Problems solved by technology

[0004] Since the installation space of piezoelectric ceramics is relatively fixed and limited, its operation requires external pressure. During long-term force activities, the installation space will be deformed. When the piezoelectric ceramics tilts with the installation space, the pressure will be difficult. Better to press on the surface so that it does not achieve the desired effect
