Stair-climbing and obstacle-crossing robot

Abstract

The invention provides a stair-climbing and obstacle-crossing robot. The stair-climbing and obstacle-crossing robot is characterized in that the structures of second telescoping support cylinders are same as those of first telescoping support cylinders, each first telescoping support cylinder comprises a plurality of sleeves, wherein the sleeves are arranged in a sleeved mode in sequence, and the sleeves are in slipping fit with each other. Each group of sleeves comprises the upper sleeve, the middle sleeves and the lower sleeve, wherein an installation frame is installed at the upper end of the upper sleeve. A scissor-fork type connecting rod mechanism is arranged in each group of sleeves, the lower ends of the scissor-fork type connecting rod mechanisms are connected with the lower sleeves respectively, the upper ends of the scissor-fork type connecting rod mechanisms extend out of the upper sleeves respectively, the scissor-fork type connecting rod mechanisms are connected with first drive transmission mechanisms driving the scissor-fork type connecting rod mechanisms to extend and retract respectively, the first drive transmission mechanisms are installed on the installation frames respectively, and the installation frames are hinged to connecting pieces respectively. The stair-climbing and obstacle-crossing robot has the advantages that the scissor-fork type connecting rod mechanisms have better telescopic adjustment capacity and higher telescopic adjustment speed, meanwhile, the strength capacity is ensured, the supporting is more stable and firmer, the stair-climbing and obstacle-crossing capacity of the stair-climbing and obstacle-crossing robot is higher, and the speed in the stair-climbing and obstacle-crossing processes is higher.

Description

technical field [0001] The invention relates to a robot, in particular to a ladder-climbing and obstacle-surmounting robot. Background technique [0002] Wheelchairs are a means of transportation for physically disabled or handicapped people, but conventional wheelchairs have poor adaptability and mobility. If they encounter complex road conditions such as uphill and downhill, stairs, obstacles, etc., it will be difficult for wheelchairs to pass. [0003] Therefore, be badly in need of developing a kind of adaptable ability, flexible maneuverability good, and can pass through the obstacle-crossing wheelchair of various complex road conditions. [0004] The applicant once invented and created an obstacle-crossing wheelchair, and applied for an invention patent. Through the first drive transmission mechanism, the mutual transformation between the first foot and the second foot is realized, and the front and rear swing is realized. The first foot is realized through the second ...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the deficiencies of the background technology, the present invention provides a ladder-climbing obstacle-surmounting robot, which solves the problems of the existing obstacle-climbing wheelchairs, such as slow climbing ladders, complicated structure, heavy weight, and unsmooth and inconvenient adjustment actions.
