Force-sensitive elastic body material based vibration engine

Abstract

The invention provides a force-sensitive elastic body material based vibration engine. The vibration engine comprises an inductive coil, a magnetic source, a force-sensitive elastic body used for generating deformation under an external force action and changing the magnetic flux ratio of a magnetic circuit, and a vibration conversion unit used for converting the external vibration into axial reciprocating movement along the inductive coil, wherein force-sensitive elastic body is driven by the vibration conversion unit under the external vibration to be deformed so as to further change the magnetic flux ratio and to generate induced electromotive force through the inductive coil. According to the vibration engine, when the vibration apparatus vibrates, a vibration mass block displaces relative to the base to enable the force-sensitive elastic body to be subjected to stretching / compression deformation; the magnetic resistance of the magnetic circuit is changed due to the changes of the magnetic conductivity caused by deformations, so that the magnetic flux passing through the coil is changed consequently to generate the induced electromotive force; and in addition, the force-sensitive elastic body material based vibration engine is simple in structure, small in size and quite high in reliability under long-term operations.

Description

technical field [0001] The invention relates to the field of physics, in particular to a vibration engine based on a force-sensitive elastic body material. Background technique [0002] In the past 100 years, developed countries have completed industrialization successively, consuming a large amount of natural resources on the earth, especially energy resources. At present, some developing countries are entering the stage of industrialization, and the increase in energy consumption is an objective necessity of economic and social development. In recent years my country's national economy has developed rapidly, but at the same time it is accompanied by many problems. In my country, building energy consumption accounts for more than 27% of the total energy consumption, and it is still increasing at a rate of 1 percentage point per year. Statistics from the Ministry of Construction show that my country's new buildings have been basically designed according to energy-saving stand...
