Energy converter for converting mechanical energy into electrical energy, has swing arm including non-linear spring-stages, which exhibit different spring-stiffnesses so that higher-spring-stiffness is achieved at higher deflections

摘要

The converter (1) has a swing arm (7) consisting of non-linear spring-stages (15), which exhibit different spring-stiffnesses so that higher-spring-stiffness is achieved at higher deflections. A non-linear spring is formed by a spring assembly comprising the spring-stages, where the spring-stages are formed of individual springs. The swing arm comprises a permanent magnet (9) and two inference-elements (10) arranged adjacent to each other, where the swing arm is manually movable by an actuating element.
