Omni wheel and mobile equipment

Abstract

The invention provides an omnidirectional wheel and mobile equipment, which relates to the technical field of mobile devices and is used to solve the technical problems that existing omnidirectional wheels are prone to noise and vibration and have poor running stability. The omnidirectional wheel includes a hub bracket, a first roller assembly, the second roller assembly; the first roller assembly includes a first shaft and a first roller, the first roller includes a connected rim portion and a spoke portion, the spoke portion is located in the middle of the rim portion, and the two adjacent to the first roller assembly Part of the structure of the second roller assembly extends into the space on both sides of the spoke portion of the first roller assembly; the first roller assembly also includes a first bracket unit and a second bracket unit that are separately arranged. The first fixing part of the unit and the second fixing part of the second bracket unit are respectively located in spaces on both sides of the spoke part in the axial direction, and are fixedly connected with the first shaft. The omnidirectional wheel provided by the invention has low noise and vibration, high running stability and low production cost.

Description

technical field [0001] The invention relates to the technical field of mobile devices, in particular to an omnidirectional wheel and mobile equipment. Background technique [0002] Omni wheels are a large wheel composed of multiple wheels. The omni wheel can rotate around the hub as a whole, and each wheel can rotate around its own center, so it can roll forward or slide left and right to move the device. Combining multiple omnidirectional wheels together can achieve 360-degree omnidirectional movement. [0003] Omni-directional wheels are divided into single-row omni-directional wheels and multi-row omni-directional wheels. Among them, multi-row omni-directional wheels form a projected coherent tire surface through multiple rows of small rollers arranged alternately. Since the rollers have a multi-row structure, when used on bumpy roads, the roller bracket is very easy to collide with obstacles, causing inconvenience in use. And because it is a multi-row structure, the st...

AI Technical Summary

Problems solved by technology

However, due to the large gap between the driven wheels of the single-row omnidirectional wheel, the continuity of the whole wheel is poor, so relatively large noise and vibration will be generated.

[0004] In order to solve the problem of continuity, two small roller brackets are usually used to fix the large roller, but in actual production and application, there are problems of assembly difficulty, noise and vibration during use, and poor running stability.

In addition, the large roller and the small roller can be set in two halves and fixed on the bracket by both sides of the bracket. Although this solves the assembly problem, there will still be noise and vibration in actual use.
