Abstract

The invention relates to the technical field of robots, in particular to an electric stairs-climbing mechanism with a multi-connecting-rod transmission mechanism. The electric stairs-climbing mechanism comprises a handle, a rack, a rear dragging plate, wheels and stairs-climbing assemblies (a motor, a driver and multi-connecting-rod structures). The wheels are arranged at two ends of the rack, and the motor and the driver are fixed to one side of the rack. One multi-connecting-rod structure is installed along the left side and the right side of the motor and the driver respectively, and the multi-connecting-rod structures are symmetrical distributed. The two multi-connecting-rod structures are connected through the tail ends of connecting rods standing on the ground to form a whole, and the connecting rods standing on the ground are respectively in rotary connection with contact wheels. Stairs climbing is stable and the efficiency is high by adopting the multi-connecting-rod transmission mechanism adopting the symmetrical design and utilizing quick-return characteristics of the multi-connecting-rod mechanism, the safety and stability in the using process are high, and the electric stairs-climbing mechanism is driven through the motor and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an electric stair-climbing mechanism whose transmission mechanism is a multi-link type. Background technique [0002] The electric load climbing machine is often used in the field of logistics handling, so that the staff can easily carry heavy objects up and down the stairs. At present, in the field of domestic logistics industry, the process of delivering goods is mostly carried out by manpower. If it is a heavy and large item, it needs to rely on two or more manual laborers to deliver it upstairs. The electric load stair climbing machine can largely relieve the dependence on the physical strength and experience of logistics distribution personnel, and can easily and quickly transport goods to designated floors. Most current electric stair climbers use a star wheel structure, but the stability is not high, and the star wheel structure takes up a lot of space and is not conducive...
