Problems solved by technology

Although there is no problem of wire winding in this device, due to the physical contact in this way, long-term friction will wear out the contacts, which will lead to open circuits, and eventually make the "conductive slip ring fail" and reduce the life of the electromechanical equipment load.

Abstract

The invention discloses an efficient redundant wireless power transmission device which comprises a rotating unit, a signal transmission unit and a redundant structure. The redundant structure comprises a plurality of power transmission units and a magnetic field shielding unit. The power transmission unit comprises a fixed end power transmission carrier module and a rotating end power transmission carrier module; the magnetic field shielding unit comprises a fixed end magnetic field shielding module and a rotating end magnetic field shielding module. The rotating end magnetic field shielding module is arranged on the outer side of the rotating unit; and the power transmission unit and the signal transmission unit are respectively used for wirelessly transmitting power and signals from the fixed end to the rotating end in the rotating process of the rotating unit. The efficient redundant wireless power transmission device has the advantages of being small in abrasion and long in service life, simultaneous transmission of multiple strands of power can be achieved, and the power transmission function can reach enough efficiency.

Description

Technical field [0001] The present invention relates to the field of wireless power transmission technology, and particularly relates to an efficient redundancy wireless power transmission apparatus. Background technique [0002] Currently in the field of electrical and mechanical equipment, used mainly by the fixed side "contacts have conductive slip ring," the end-contact manner to the rotary power transfer transmission power. Although this apparatus, the wire is wound with no problem, but because there is a physical contact with the embodiment, the long-term friction contact wear, leading to open, so that the final "slip ring failure", reduce the life of electrical equipment loads. Inventive content [0003] The present invention addresses the above problems of the prior art, to provide a redundant efficient wireless power transfer means, having less wear, long life advantages, and enabling simultaneous transmission of multiple strands power, power transfer function achieved ...
