Abstract
An electric step, including a chassis, a housing, a motor, and two pedals. The housing is fixedly arranged on the chassis. A horizontal central shaft is fixedly arranged in the housing. Each of both ends of the central shaft is arranged with a turntable. An inner end of each pedal is arranged on a corresponding turntable. An axis of the pedal deviates from an axis of the central shaft. The motor is fixedly arranged in the housing and configured to drive the turntable to rotate via a transmission mechanism.
