Energy harvesting arrangement and electronic locking system

Abstract

Energy harvesting arrangement (12) for an electronic locking system (116), the energy harvesting arrangement (12) comprising a driven member (32) for driving an electric generator (34), the driven member (32) being arranged to rotate about a driven member rotational axis (74); a drive member (30) movable between a starting position (70), in which the drive member (30) does not engage the driven member (32), and a releasing position (112), in which the drive member (30) can drivingly engage the driven member (32); a harvesting elastic element (40) arranged to force the drive member (30) towards the starting position (70) and arranged to store mechanical energy from displacement of the drive member (30) from the starting position (70); and a release mechanism (42) arranged to release mechanical energy stored in the harvesting elastic element (40) to a returning movable of the drive member (30) from the releasing position (112) to the starting position (70). An electronic locking system (116) is also provided.
