Wheeled obstacle-surmounting robot

Abstract

Provided is a wheeled obstacle-surmounting robot. A telescopic support cylinder comprises a plurality of sleeves which are sleeved with each other sequentially and slidably matched with each other, wherein the sleeves comprises an upper sleeve body, a plurality of middle sleeve bodies and a lower sleeve body, and a mounting frame is arranged at the upper end of the upper sleeve body; a scissor-fork linkage mechanism is arranged in the sleeves, and the lower end of the scissor-fork linkage mechanism is connected with the lower sleeve body; the upper end of the scissor-fork linkage mechanism extends out of the upper sleeve body and is connected with a first drive transmission mechanism which drives the scissor-fork linkage mechanism to expand and contract, and the first drive transmission mechanism is mounted at a mounting frame; the mounting frame is hinged to a connecting piece. According to the wheeled obstacle-surmounting robot, the scissor-fork linkage mechanism is better in telescopic adjustment ability and faster in telescopic adjustment speed, and meanwhile is also arranged in the sleeves which are sleeved with each other sequentially and slidably matched with each other; through the combination of the scissor-fork linkage mechanism and the sleeves, not only can the telescopic range and the telescopic speed be ensured, bu also the strength capability can be ensured; therefore, the support effect is more stable and tighter, the obstacle-surmounting ability of a ladder-climbing and obstacle-surmounting robot is stronger, and the obstacle-surmounting speed is faster.

Description

technical field [0001] The invention relates to a wheelchair robot, in particular to a wheeled 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 d...

AI Technical Summary

Problems solved by technology

[0005] However, the walking feet of the above-mentioned obstacle-crossing wheelchair have a small telescopic range and weak obstacle-crossing ability. At the same time, it needs to be realized by cooperation between the first foot and the second foot. The structure is relatively complicated, and the weight is heavy, so it is difficult to transport.
