▎ 摘　　要

NOVELTY - The power supply has a rotating ring provided with a mounting chamber. A lateral displacement propeller is arranged on a lateral end of a mounting chamber. A rotating shaft of the lateral displacement propeller is arranged in the mounting chamber for driving a lateral rotary propeller to rotate. A side wall of the rotating ring is formed with an annular groove that is connected with the mounting chamber. An annular graphene conductive carbon brush is embedded in the annular groove. An each side-shift driving motor is electrically connected with the annular carbon brush by a lead wire. USE - Graphene carbon brush power supply for robot. ADVANTAGE - The annular graphene conductive carbon brush improves conducting performance. The power supply has low wear rate, stable operation, and reduces noise. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene carbon brush power supply.
