| 摘要 |
<p>The invention concerns a portable device for converting mechanical energy into electric power for powering a charge (80), comprising a mechanical system (10, 20) actuated by a user's manual action for rotating the rotor (32) of an electric voltage generator (30) powering the charge via an electric circuit (40), the mechanical system (10, 20) including an unwinding link (14) wound around a winding shaft (11), enabling the user to pull on one end of the unwinding link to unwind and drive the rotor (30) of the electric generator (30) in a first rotational direction, the mechanical system further including elastic return means (12) adapted to rewind the unwinding link around the winding shaft, when the user stops pulling the unwinding link, and to drive the rotor in a second rotational direction, opposite to the first rotational direction.</p> |
