Angle, the shape of groove is in circular ring shape.
As another technical solution, the shape of the magnetism plate body is rounded, and the shape of groove is in circular ring shape.
As another technical solution, the shape of the magnetism plate body is rectangle, and the shape of groove is in side's annular.
The utility model advantageous effect is：By opening up groove in the top end face of magnetic plate body, coil circle body is placed
Wherein, closing magnetic path structure is formed, so as to utilize the originals such as the magnetic resistance of closed magnetic circuit is small, magnetic induction intensity is big, magnetic field intensity is big
Reason reduces the leakage magnetic flux in wireless charging, is converted into main flux to greatest extent, achievees the purpose that improve transformation efficiency；And
The depth of groove is 0.2~2 centimetre, and the deep equality of the depth of groove and notch, make coil circle body and coil exit it
Between seamlessly transit, the width of groove is 2~10 centimetres, and the width of notch is 2~8 centimetres, and the thickness of magnetic plate body is 0.5~3
Centimetre, the design of this structure, the problem of can reducing the magnetic disturbance brought by leakage field and high fever, makes product have the preferable EMI special
Property, product using process medium temperature rise reduce, be particularly suitable for the powerful wireless charging products of more than 200W, as electric bicycle,
The wireless chargings products such as electric vehicle, power-operated mower, electronic transportation fork-truck.
