The invention belongs to the technical field of automobile electronics application, and discloses a power supply device used for a wheel. The power supply device comprises copper bars, insulation layers, a pushing part and sliding contact parts. The copper bars are arranged on the inner side wall of a bead seat of a wheel hub in the circumferential direction of the wheel hub, and provided with power output leads in an electrical connection mode. The insulation layers are arranged between the inner side wall of the bead seat of the wheel hub and the copper bars. The pushing part is fixed to the position, corresponding to the installing positions of the copper bars, of a wheel support. One end of each sliding contact part is supported on the pushing head of the pushing part, and the other end of each sliding contact part corresponds to the corresponding copper bar. The pushing part is used for pushing the sliding contact parts to the copper bars so that the sliding contact parts can rotate along with the wheel hub to be in sliding fit with the copper bars. The sliding contact parts are electrically connected with an automobile storage battery through lines. The power supply device has the advantages that the trouble of replacing the battery regularly can be avoided, and according to using needs, direct-current power output to loads can be connected or disconnected; because one or more copper bars are arranged, power can be supplied to the multiple loads at the same time.
