Portable electronic lock

A portable electronic lock, comprising a lock body and a securing part that is movable relative to the lock body between a closed position and an open position;

• wherein the lock body comprises an electric motor having an electrically driven rotor, a latch that is drive-effectively coupled to the rotor, and a return spring;
• wherein the rotor is configured to selectively drive the latch from a locking position, in which the securing part located in the closed position is locked to the lock body, into an unlocking position, in which the securing part is released for a movement into the open position;
• wherein the return spring is configured to mechanically drive the latch from the unlocking position into the locking position, wherein the mechanical driving of the latch is triggered by a moving of the securing part from the open position into the closed position;
• with the latch being drive-effectively coupled to the rotor of the electric motor such that the mechanical driving of the latch effects a forced rotational movement of the rotor, wherein the electric motor generates an electrical voltage due to the forced rotational movement of the rotor.
