NEW WIRELESS ELECTRIC ENERGY TRANSMISSION MAGNETIC PATH COUPLING MECHANISM

摘要

Proposed in the present invention is a new wireless electric energy transmission magnetic path coupling mechanism, comprising: a primary side energy emission cushion and a secondary side energy collection cushion arranged opposite and in parallel with each other. The primary side energy emission cushion and the secondary side energy collection cushion are both of a two-layered structure, with one layer being a coil layer formed by winding a Litz wire, and the other layer being a magnetic core layer. The coil layer and the magnetic core layer are both of a centrosymmetric structure. The coil layer comprises two identical orthogonally laminated rectangular coils, and the magnetic core layer is a Sudoku-shaped grid layer comprising eight ferrite strips with the same length. The length of the ferrite strips is equal to the length of the rectangular coils. The coil layers of the primary side energy emission cushion and the secondary side energy collection cushion are opposite each other, and opposite surfaces of the primary side energy emission cushion and the secondary side energy collection cushion are in mirror symmetry with each other. The mechanism has a higher coupling coefficient, and a wider deviation allowance range can be simultaneously provided in three directions, such as two horizontal directions perpendicular to each other and a direction of rotation around a central axis of the mechanism.
