Abstract

The invention relates to an overturn climbing device based on a gear rack mechanism, and belongs to the technical field of mechanical design and manufacture. The overturn climbing device comprises a body, controllable driving units and two crank arms, wherein the two crank arms with the same structures are symmetrically mounted on two sides of the body, and the driving units are fixedly connected with the body. The overturn climbing device has the advantages of novel structure, fine safety and stability in the use process, small number of the driving units, low driving torque in the overturn process, compact integral structure, light weight and high obstacle crossing adaptability.

Description

technical field [0001] The patent of the present invention belongs to the technical field of mechanical design and manufacturing, and relates to a flipping obstacle-crossing device, specifically, a rack-and-pinion flipping and climbing mechanism applied to stair-climbing wheelchairs, and can also be applied to various stair-climbing and obstacle-crossing robots middle. Background technique [0002] As a common means of transportation for the elderly, infirm and physically disabled, wheelchairs are in increasing demand, especially with the advent of an aging society and the increase in the number of disabled people due to frequent natural disasters in recent years. However, they are generally only suitable for use on flat ground, and rarely have the ability to climb stairs and overcome roadblocks, which brings a lot of inconvenience to wheelchair users. With the acceleration of the pace of urbanization in our country, more and more wheelchair users need to face the actual si...
