Mobile equipment, and Mecanum wheel and roller thereof

Abstract

The embodiment of the invention provides a roller (60). The roller is suitable for a Mecanum wheel (200). The roller comprises a roller body (62), a rolling shaft (61) and a rolling shaft sleeve (64),wherein a roller body through hole (622) extending in the axial direction of the roller body is formed in the roller body (62); the rolling shaft (61) comprises a connecting part (611) and a stoppingblock rolling shaft end (612) connected to one end of the connecting part ( 611 ), and the connecting part (611) is arranged in the roller body through hole (622); the rolling shaft sleeve (64) comprises a connecting sleeve part (641) and a stopping block rolling shaft sleeve end (642) connected to one end of the connecting sleeve part (641), and the connecting sleeve part (641) is arranged in the roller body through hole (622); the connecting part (611) is inserted into the connecting sleeve part (641), and the connecting part (611) is fixedly connected to the connecting sleeve part (641); the stopping block rolling shaft end (612) and the stopping block rolling shaft sleeve end (642) are separately connected to both sides of the roller body through hole (622) in a clamped mode; and theroller body can rotate around the rolling shaft (61) and the rolling shaft sleeve (64). The rolling shaft (61) and rolling shaft sleeve (64) of the roller (60) can improve connection firmness betweenthe roller (60) and a rim (20).

Description

technical field [0001] The embodiments of the present invention relate to the field of mobile devices, and in particular, to a mobile device, a mecanum wheel and a scroll wheel thereof. Background technique [0002] The Mecanum wheel is a kind of omnidirectional wheel, and there are many small rollers distributed obliquely on the rim, and the movement is realized by the rolling of the rollers. [0003] For the sports equipment based on the mecanum wheel, different combinations can be obtained by separately controlling the movement directions of the four mecanum wheels. Without any rotation of the mecanum wheel body, the movement equipment can move forward, Movement methods such as back, lateral, oblique, rotation and their combination can flexibly and conveniently realize all-round movement functions, which is very suitable for occasions such as limited transfer space and narrow working passages, so it has broad application prospects in the fields of manufacturing and wareho...
