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 a high-efficiency redundant wireless power transmission device, comprising: a rotating unit, a signal transmission unit and a redundant structure; the redundant structure includes: a plurality of power transmission units and a magnetic field shielding unit; the power transmission unit includes: a fixed end and a The rotating end power transmission carrier module; the magnetic field shielding unit includes: a fixed end and a rotating end magnetic field shielding module; the rotating end magnetic field shielding module is arranged on the outside of the rotating unit; the power transmission unit and the signal transmission unit are respectively used in the rotating process of the rotating unit. Wirelessly transmit power and signals from the fixed end to the rotating end. The high-efficiency redundant wireless power transmission device of the present invention has the advantages of less wear and longer life, and can realize simultaneous transmission of multiple powers, and the power transmission function can achieve sufficient efficiency.

Description

technical field [0001] The present invention relates to the technical field of wireless power transmission, in particular to an efficient redundant wireless power transmission device. Background technique [0002] At present, in the field of electromechanical equipment, the power transmission from the fixed end to the rotating end mainly adopts the contact method of "conductive slip ring with contacts" for power transmission. Although there is no problem of wire winding in this device, due to the physical contact in this method, long-term friction will wear the contacts, which will lead to an open circuit, which will eventually make the "conductive slip ring fail" and reduce the life of the electromechanical equipment load. SUMMARY OF THE INVENTION [0003] Aiming at the above problems in the prior art, the present invention proposes a high-efficiency redundant wireless power transmission device, which has the advantages of less wear and longer life, and can realize simult...
