The invention belongs to the technical field of wireless energy transmission, and provides a wireless energy emission mechanism based on a concave-convex magnetic core and a parameter design method thereof. The mechanism comprises a magnetic core and a coil, and the magnetic core is consists of a plurality of ferrite magnetic strips which are distributed in an annular array, the upper surface of each magnetic strip is provided with two sections of concave-convex parts, After the plurality of magnetic strips are distributed in an annular array, the concave-convex parts form two annular coil accommodating grooves, and the coils are divided into two groups and are respectively wound in the two coil accommodating grooves in a plane-tight manner. And the inner and outer groups of coils are connected in series. The simulation software analysis shows that the structure can realize that the transverse anti-offset capability and the longitudinal transmission distance at the other mutual inductance end are obviously superior to the existing electromagnetic coupling mechanism under the same induction voltage condition, and the lateral and longitudinal offset tolerance of the wireless energy transmission system is improved.
