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 electromechanical locking device that has an electric motor, an entrainer, a rotating latch, a return spring, a blocking mechanism, and a control circuit for controlling the electric motor,

• wherein the electric motor drives the entrainer for a rotational movement between a starting position and a release position,
• wherein the rotating latch is coupled to the entrainer with a rotational clearance that at least corresponds to the angle of rotation of the entrainer during a movement between the starting position and the release position, wherein the rotating latch is preloaded by the return spring in a direction of a locking position in which the securing part located in the closed position is locked to the lock body, wherein the rotating latch, starting from its locking position and starting from the starting position of the entrainer, can be driven by the entrainer against the force of the return spring into an unlocking position in which the securing part is unlocked for a movement into the open position,
• wherein the blocking mechanism is configured to mechanically block the rotating latch in the unlocking position against a return movement by the return spring as long as the securing part is in the open position,
• wherein the control circuit is configured, in response to an unlocking command, to rotate the entrainer from the starting position into the release position in order to electrically drive the rotating latch into the unlocking position and to tension the return spring, and to then rotate the entrainer back into its starting position utilizing the rotational clearance while the rotating latch is blocked in the unlocking position by the blocking mechanism,
• wherein, by moving the securing part from the open position into the closed position, the blocking mechanism is released for an unblocking of the rotating latch and thus a relaxing of the return spring so that the rotating latch is mechanically driven by the return spring to make a return movement into the locking position;
• wherein the electromechanical locking device comprises at least one cam fixed for rotation with the entrainer;
• wherein the electromechanical locking device comprises a switch that is actuated by the at least one cam, wherein the control circuit controls the electric motor in dependence on an actuation of the switch;
• wherein the switch has a rocker lever that is preloaded into a center position and that, in dependence on a direction of rotation of the at least one cam, is actuated by the at least one cam either in a first direction or in a second direction opposite thereto.

• wherein, by moving the securing part from the open position into the closed position, the blocking mechanism is released for an unblocking of the rotating latch and thus a relaxing of the return spring so that the rotating latch is mechanically driven by the return spring to make a return movement into the locking position;
• wherein the electromechanical locking device comprises at least one cam fixed for rotation with the entrainer;
• wherein the electromechanical locking device comprises a switch that has a rocker lever actuated by the at least one cam;
• wherein the rocker lever is flipped by the at least one cam, depending on a movement of the at least one cam in a first direction of rotation or a movement of the at least one cam in a second direction of rotation opposite to the first direction of rotation, either in the first direction or in the second direction;
• wherein the control circuit controls the electric motor in dependence on an actuation of the switch, wherein the control circuit distinguishes between the first direction and the second direction into which the rocker lever is flipped.
