Problems solved by technology

However, the suspension part of some existing omnidirectional mobile platforms with mecanum wheels is too complicated and heavy, and the structure is not compact enough, which will sacrifice part of the bearing capacity, and will also increase instability and production costs

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] An omnidirectional mobile platform with independent suspension in the middle of the hinge based on mecanum wheels, including a bearing platform, an independent suspension mechanism, and a chassis wheel shaft mechanism. There are four independent suspension mechanisms and chassis axle mechanisms, and each independent suspension mechanism and chassis axle mechanism form a group, and the four independent suspension mechanisms and chassis axle mechanisms are respectively symmetrically arranged at the four corners of the bearing platform. The structures of the four sets of independent suspension mechanisms, the chassis axle mechanism, and the installation positions are mirror-symmetrical in front, rear, left, and right. Due to the omnidirectional mobility of the mecanum wheels and the symmetry of the front, rear, left and right suspensions, it can ensure th...

Abstract

A hinge-mounted independent suspension omni-directional mobile platform based on McNum wheel comprises a bearing platform, independent suspension mechanisms and chassis wheel-axle mechanisms. The fourgroups of independent suspension mechanisms and the chassis wheel-axle mechanisms are installed at four vertices of the bearing platform, each group of independent suspension mechanisms, and the chassis wheel-axle mechanism comprises an independent suspension mechanism and a chassis wheel-axle mechanism. The independent suspension mechanisms comprise angle codes, shock absorbers, motor fixing plates and hinges. The motor fixing plate is arranged below the bearing platform, and the angle codes are respectively installed on the bearing platform and the motor fixing plates. The two ends of the shock absorber are respectively connected with the bearing platform and the motor fixing plates through the angle codes, and the inner end of the motor fixing plates is connected with the bearing platform through the hinges. The chassis wheel-axle mechanisms are connected with the motor fixing plates. The hinge-mounted independent suspension omni-directional mobile platform has the advantages of simple structure, compact structure, high bearing capacity, good stability and the like. The invention belongs to the technical field of mobile devices based on McNam wheels.

Description

technical field [0001] The invention belongs to the technical field of mobile devices based on mecanum wheels, in particular to a hinged middle independent suspension omnidirectional mobile platform based on mecanum wheels. Background technique [0002] With the continuous development of automation technology, various mobile platforms with motion diversity and flexibility have been widely used in many fields, and the omnidirectional mobile platform based on the mecanum wheel is one of them. Mecanum wheels can realize movement modes such as forward movement, lateral movement, oblique movement, rotation and combinations thereof, but in fact, due to the hard material of the mecanum wheel and the unevenness of the road surface, the coefficient of friction is different, making each mecanum wheel The thumb wheel has uneven bearing capacity, so the entire omnidirectional mobile platform will not be well controlled. In order to improve these problems, the existing omni-directional ...
