Wheel leg compound motion platform

Abstract

A wheel leg compound motion platform comprises a stand as well as more than two front wheel leg assemblies and more than two rear wheel leg assemblies which are connected to the bottom of the stand, wherein the stand comprises a front body plate and a rear body plate which are hinged together; the front wheel leg assembly and the rear wheel leg assembly respectively comprise a thigh swing arm, a wheel mechanism and a crus swing arm; one end of the thigh swing arm is hinged to the stand and can swing around a hinge point; the other end of the thigh swing arm is connected with one end of the crus swing arm to form an elbow part and can swing around the elbow part for achieving folding; a wheel mechanism is mounted on an intermediate section of the crus swing arm; and a foot part for finishing the walking is arranged at the tail end of the bottom of the crus swing arm. The wheel leg compound motion platform disclosed by the invention has the advantages of simple and compact structure, stability and reliability in motion, favorable controllability, simpleness in motion state switching, strong obstacle combing ability and the like.

Description

technical field [0001] The invention mainly relates to the field of sports equipment, in particular to a sports platform with a compound design of wheels and legs. Background technique [0002] At present, in the motion mechanism of the motion platform, wheel type, leg type and crawler type are generally used. The wheel-type motion mechanism has the advantages of simple structure and fast motion speed, but it is not suitable for crossing obstacles such as trenches and stairs, and its ability to overcome obstacles is poor; the leg-type motion mechanism has high passability and can adapt to complex ground motion environments, but the motion speed is slower. Slow, complex mechanism and control; tracked motion mechanism has strong traffic capacity and good adaptability in natural environments such as soft and uneven terrain, but has large frictional resistance, heavy weight, complex mechanism, and high energy consumption. shortcoming. [0003] Some practitioners have proposed ...

AI Technical Summary

Problems solved by technology

[0005] (2) In the process of mode conversion, special conversion and adjustment mechanisms are generally required, which increases the complexity of the mechanism

At the same time, due to the complexity of mode switching, the motion efficiency is directly reduced

[0006] (3) In some wheel-leg compound motion platforms, the leg motion is only used as an auxiliary wheel motion, and the characteristics of the strong obstacle-crossing ability of the leg motion have not been fully utilized, and the stability of the motion platform is also poor.
