Abstract

The invention discloses an omnidirectional mobile platform for Mecanum wheels. The omnidirectional mobile platform comprises a frame, the Mecanum wheels, independent suspension modules, power transmission devices, a master control box and a battery pack. Each Mecanum wheel is arranged below the frame through the corresponding independent suspension module. The master control box can cooperatively control the rotation speeds and steering of all the Mecanum wheels. Each independent suspension module comprises two cantilevers arranged in parallel, a connecting board fixedly connecting the two cantilevers and a damper; one end of each damper is connected with the corresponding connecting board, and the other end of each damper is connected with the frame; and one end of each of every two cantilevers is connected with a transmission shaft through bearings with seats, wherein each transmission shaft is sleeved with the corresponding Mecanum wheel. After the structure is adopted, the omnidirectional movement can be flexibly achieved in the plane, the structure is simple and reliable, the overall bearing capacity is high, it can be guaranteed that the Mecanum wheels can make full contact with the ground, and the operation stability and control accuracy of the mobile platform are improved; and meanwhile the mobile platform has the beneficial effects of being compact in structure, high in applicability and suitable for popularization.

Description

technical field [0001] The invention relates to a mobile device, which belongs to the technical field of transportation and transportation devices, in particular to an omnidirectional mobile platform with Mecanum wheels. Background technique [0002] With the continuous expansion of the manufacturing industry and the continuous development of automatic control technology, the loadable mobile equipment based on the wheeled mobile platform has been widely used in the fields of manufacturing automation, storage material transportation, industrial robots and daily life. Traditional wheeled mobile equipment usually has many unfavorable factors such as large turning radius and inability to move laterally, so its space utilization rate is low and movement flexibility is poor during operation. [0003] Compared with other omnidirectional wheels such as ball wheels and continuous switching wheels, Mecanum wheels have a stronger load-carrying capacity; at the same time, because of the...
