Abstract

The invention provides an integrated type piezoelectric energy conversion module and the application thereof. The module comprises a base plate and multiple substrates on the base plate. A cover body is arranged on each substrate in a matched manner. A piezoelectric transducer is installed in an installation hole in each substrate. Through cooperation of sliding rails and sliding grooves, the cover bodies are capable of covering the base. A side substrate is installed on each substrate. A rectification voltage stabilizing module installation cavity is processed in each side substrate. A contact electrode input end and a contact electrode output end are imbedded into each side substrate at the bottom of the corresponding rectification voltage stabilizing module installation cavity. A pair of fixed conductive sheets which are in contact with and connected with a pair of electrodes on each piezoelectric transducer are installed in the corresponding installation hole. The fixed conducive sheets are connected with the contact electrode input ends to input electric energy generated by the piezoelectric transducers to voltage stabilization current rectification modules. According to the invention, output stability of energy can be ensured; installation and use steps are simplified; construction cost is reduced; by converting vertical vibration deformation into annular deformation, energy utilization rate is improved; and energy output of a power generation road is effectively improved.

Description

technical field [0001] The invention belongs to the field of road engineering and relates to a piezoelectric transducer, in particular to an integrated piezoelectric transducer module and its application. Background technique [0002] The energy problem has become a worldwide problem. The energy crisis has seriously curbed the country's economic development and the improvement of the people's living standards. The development of clean energy has become an important part of the national energy strategy development. With the rapid development of road engineering in my country, the road surface will bear a huge amount of traffic throughout its service life. Under the action of traffic load, the road surface will vibrate and deform to generate considerable mechanical energy, which cannot be effectively utilized. The power generation surface technology uses the wheel load pressure generated by various vehicles on the road surface during driving, and transmits it to the transducer...
