Full ground type manned robot with rear wheel lifting mechanism and up and down step method

Abstract

The invention discloses a full-ground manned robot with a rear wheel lifting mechanism. The full-ground manned robot consists of a wheelchair main body and a walking mechanism, wherein the walking mechanism comprises a base component, a transmission component and a crawler mechanism and a front wheel mechanism which are symmetrically arranged, the base component drives the crawler mechanism to operate through a transmission component; the base component comprises a base bracket, an axle speed reduction motor, a crawler speed reduction motor, an axle, a main bearing seat and a rear wheel lifting mechanism; the rear wheel lifting mechanism comprises a telescopic bracket arranged at the bottom end of the base bracket, a hydraulic rod is arranged on the telescopic bracket, and a hub motor is arranged at the bottom end of the telescopic bracket; the wheelchair main body is arranged on the base bracket through a suspension mechanism, and the rear side of the upper part of the wheelchair mainbody is provided with a hydraulic buffer connected with the base bracket. The full-ground manned robot also discloses a full-ground manned robot provided with a rear wheel lifting mechanism and an up-and-down step method. The full-ground manned robot with a rear wheel lifting mechanism is novel in design, stable in walking, comfortable to ride, safe and reliable in climbing stairs.

Description

technical field [0001] The invention relates to the technical field of mobile devices, in particular to an all-terrain manned robot equipped with a rear wheel lifting mechanism and a method for going up and down steps. Background technique [0002] At present, wheelchairs are an indispensable means of transportation for the elderly, infirm and those with lower limb disabilities. They use wheeled sports and can only walk on flat ground, but cannot cross obstacles such as steps and thresholds, let alone climb steps. Therefore, the range of activities of wheelchair users is greatly restricted. Wheelchair users living in buildings without elevators cannot go up and down the steps, which affects their going out to participate in social activities. my country has rapidly entered an aging society, and the travel problems of the elderly have become increasingly prominent. Contents of the invention [0003] In order to overcome the difficulties existing in existing wheelchairs wh...
