Omni wheel and moving device

A moving device, comprising a body and an omni wheel, wherein the omni wheel comprises a hub bracket and a plurality of roller components respectively connected to the hub bracket, wherein

• each of the plurality of roller components comprises a first roller assembly and a second roller assembly, the first roller assembly comprising a roller bracket and a first roller structure arranged on the roller bracket, and the second roller assembly comprising a second shaft and a second roller structure mounted to the second shaft;
• wherein in one of the plurality of roller components, the second roller structure is axially limited with respect to the roller bracket and the second shaft;
• wherein the roller bracket is further provided with a first connection structure, and the second shaft comprises a second shaft body and a limiting portion protruding from an outer peripheral surface of the second shaft body;
• and wherein the second shaft body is connected and locked to the first connection structure to axially limit the second roller structure with respect to the limiting portion and the first connection structure;
• and
• wherein the plurality of roller components are arranged in a circumferential direction of the hub bracket, such that the first roller structure and the second roller structure of each of the plurality of roller components jointly form a full-circle roller structure, and wherein the first connection structure is arranged at a circumferential end of the roller bracket, another circumferential end of the roller bracket is provided with a second connection structure configured to be connected to an end portion of a second shaft body in an adjacent roller component in an insertion manner, and wherein the plurality of roller components are joined end-to-end in the circumferential direction to form the full-circle roller structure in which the first roller structure and the second roller structure of each of the plurality of roller components are alternately arranged.
