Electric stair climbing device

Abstract

The invention provides an automatic stair climbing device which comprises a pedal, a pedal support, a front support, a rear support, a sliding block, supporting columns, a spring, a positioning switch, a motor, a battery, a worm gear and a worm. As shown in the figure, the rear supporting column abuts against a first step, the front supporting column abuts against the second step, when people stands on the pedal, the motor rotates to drive the worm, the worm rotates to drive the worm gear to rotate, the pedal support fixed on the worm gear and the pedal make upward and forward movement, and the pedal support and the pedal go up a step. The worm gear continuously rotates, the pedal support and the pedal are in contact with the ground and then generate reactive force, the worm gear drives a device body to make upward and forward movement, the front support and the rear support abut against the upper step, the pedal and the device body go up alternatively and make reciprocating movement, and therefore the purpose of automatic stair climbing is achieved. The automatic stair climbing device is easy to manufacture, high in practicability, and wide in application.
