Embodiment
[0049] A packet densely wound wireless energy transmission mechanism, such as figure 1 As shown, it includes a primary side coil 1 and a primary side magnetic core. The primary side coil 1 is a loop-shaped disc coil composed of a first group of coils 101 and a second group of coils 102 wound in series. The first group of coils 101 is arranged on Inside the second group of coils 102, the size of the primary coil 1 is larger than that of the secondary coil of the wireless energy receiving mechanism.
[0050]The primary side magnetic cores include N T-shaped primary side magnetic cores 201, the T-shaped primary side magnetic cores 201 include horizontal primary side magnetic cores and vertical primary side magnetic cores, and the T-shaped primary side magnetic cores 201 are in the center Symmetrically and evenly attached to the disk surface of the primary side coil 1 along the radial direction of the back-shaped disk coil. The size of the primary coil 1 is greater than that of t...

The invention provides a packet winding type wireless energy emission mechanism and a winding parameter selection method thereof. The packet winding type wireless energy emission mechanism comprises a primary side coil and a primary side magnet core, the primary side coil is a return type disk coil serially formed by two coil sets, the first coil set is arranged inside the second coil set, and the size of the primary side coil is greater than that of a secondary side coil of the wireless energy emission mechanism. The packet winding type return-type coil is adopted at the emission end of the wireless energy emission system, so that mutual inductance coupling values and transverse resistance to migration of the system are greatly improved; when transverse migration occurs to the secondary side coil, the coil on a primary side still corresponds to the secondary side coil, the situation that always more magnetic lines penetrate the secondary side coil is guaranteed, and the receiving end is coupled to more energy; sufficient longitudinal coupling capacity is guaranteed, transverse resistance to migration is improved, flux leakage in the air is effectively reduced, and size of the coil is ensured not to increase.
Description
technical field [0001] The invention relates to the technical field of wireless energy transmission, in particular to a packet densely wound wireless energy transmitting mechanism and a winding parameter selection method thereof. Background technique [0002] With the progress of society, the development of science and technology, and the increasingly prominent environmental and energy issues, the call for the development and popularization of new energy vehicles such as electric vehicles is increasing. In terms of charging technology for electric vehicles, non-contact wireless charging technology is also developing. stand up. There are three types of non-contact wireless charging technologies used in electric vehicles, namely electromagnetic induction, microwave and electromagnetic resonance. Among them, electromagnetic induction uses the electromagnetic induction phenomenon generated between coils to transmit power, which is currently the closest to practical charging. ch...
