1. An electric step device, comprising:
a step;
a retractable mechanism comprising a mounting seat, a step seat and an arm assembly, the step being mounted to the step seat, the arm assembly being connected between the mounting seat and the step seat to drive the step to move between an extended position and a retracted position; and
an anti-collision assembly comprising a first anti-collision component and a second anti-collision component, the first anti-collision component being mounted to the step, the second anti-collision component being mounted to the mounting seat, the first anti-collision component comprising a first anti-collision seat and at least two anti-collision shafts, the at least two anti-collision shafts being mounted on the first anti-collision seat and spaced apart from each other, the second anti-collision component comprising a second anti-collision seat and at least two anti-collision grooves formed in the second anti-collision seat,
wherein in the retracted position, the at least two anti-collision shafts are fitted in the at least two anti-collision grooves in a one-to-one correspondence, and in the extended position, the at least two anti-collision shafts are disengaged from the at least two anti-collision grooves, respectively;
wherein the second anti-collision component further comprises an anti-collision seat plate and an anti-collision lug plate extending downwards from the anti-collision seat plate, the anti-collision seat plate is fixed on a top surface of the mounting seat, and the at least two anti-collision grooves are formed at a lower end of the anti-collision lug plate.
