Spring device for voltage generation in vehicles has separated permanent magnet and induction coil with spring oscillation cutting magnetic field and generating voltage

摘要

A spring device comprises two separated fixed ends (12,14), one having a permanent magnet (26) and the other an induction coil (28) together giving electro-induction (32). The coil corresponds with a spring length alteration in the field cutting magnetic lines on moving and inducing a voltage.
