The invention provides a flexible printed circuit (FPC) winding method, a bearing device and a cloud platform. The FPC winding method is used for electrical connection of a carrier device and involves a multi-layer FPC, wherein the multi-layer FPC is arranged in a lamination way and is wound around the carrier device to form a winding structure, the winding structure is provided with at least one pair of internal force offset units, each internal force offset unit comprises a first bending part and a second bending part, and the bending directions of the first bending part and the second bending part are opposite. The invention also provides the bearing device and the cloud platform which employ the FPC winding method. With the adoption of the FPC winding method, the first bending part and the second bending part are used for offsetting an internal force formed by a bending inner side of the multi-layer FPC during moving of the carrier device, the impedance of the multi-layer FPC during following motion is reduced, so that the stability of the carrier device is higher, and the motion accuracy of the carrier device is improved; and moreover, the multi-layer FPC cannot be wound in a mess mode, and the integral structure is more regular.
