Induction generator for a bi-cycle

摘要

The invention provides a generator for a bicycle. The generator has one or more driving magnets fixed to a wheel of the bicycle and an induction structure that is fixed to a frame part of the bicycle. The induction structure comprises an induction magnet and a coil. A fixture allows fixing of the driving magnets at locations where they, during operation of the bicycle, repeatedly moves towards and away from the induction magnet. The generator comprises means for reorienting the induction magnet so that it is optimally oriented when a driving magnet approaches. Such means comprises a first driving magnet or a structure of magnetisable material which is magnetisable by the driving magnet.

主权项

1. An induction generator for a vehicle for generating electric current, wherein the induction generator comprises first and second parts that are attachable to vehicle-parts, wherein one of the vehicle-parts is rotatably fixed relative to the other and, wherein:
the first part comprises first and second driving poles of opposite magnetic polarities, the second part comprises an induction magnet with first and second induction poles of opposite magnetic polarities and a coil with windings of electrically conducting wire, wherein the induction magnet is rotatably arranged relative to the coil to enable induction of a current in the coil by motion of the magnetic poles, and the first part is arranged on the moveable vehicle-part to enable the first and second poles of the first part to alternately face the induction magnet, upon motion of the vehicle-part, so as to move the induction magnet by magnetic interaction between the poles of the first part and the induction magnet, and wherein the first pole of the first part is provided at least to position or move the induction magnet before the second pole of the first part approaches the induction magnet.
