Ladder climbing mechanism

Abstract

The invention relates to a ladder climbing mechanism which comprises a vehicle body device, a wheel device, a connection limiting device and a motor. The wheel device comprises an in-wheel transmission part and an external rolling part, the in-wheel transmission part comprises an RV speed reducer and at least one bearing shaft, the input end of the RV speed reducer is connected with the output end of the motor, and a shaft structure extending out of a crankshaft at the output end of the RV speed reducer is the bearing shaft; the external rolling part comprises an elastic tire, and the elastic tire sleeves and is fixed on the outer side of a pin wheel of the RV speed reducer; the connection limiting device comprises a shaft limiting block and a bearing connecting rod, and the shaft limiting block is provided with a first shaft hole and installed on the bearing shaft through the first shaft hole. One end of the bearing connecting rod is provided with a second shaft hole and a rod limiting block close to the second shaft hole, is mounted at the tail end of the bearing shaft through the second shaft hole and is adjacent to the shaft limiting block, and the other end is connected with the vehicle body device. The ladder climbing mechanism provided by the invention can climb stairs and can efficiently run under a normal flat road condition at the same time.

Description

technical field [0001] The invention specifically relates to a climbing ladder mechanism, which belongs to the technical field of mechanical mechanisms. Background technique [0002] The information disclosed in this background section is only intended to increase some understanding of the general background of the present invention, and is not necessarily to be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Most stair climbing machines in the prior art mainly use crawler tracks, multi-legs and multi-wheels, but the structure of most of the equipment is complicated, and there is a singleness and low efficiency in the application and switching of both flat ground and stairs. Problems of performance and low load capacity. [0004] For the problem of switching between flat ground and stair road conditions, most institutions only consider the function of the mechanism on ...

Problems solved by technology

[0003] Most stair climbing machines in the prior art mainly use crawler tracks, multi-legs and multi-wheels, but the structure of most of the equipment is complicated, and there is a singleness and low efficiency in the application and switching of both flat ground and stairs. The problem of low performance and load capacity

[0004] For the problem of switching between flat ground and stair road conditions, most organizations only consider the function of the mechanism on the ladder road, but ignore its efficient driving on normal flat road conditions while climbing stairs.
