The invention provides a magnetic coupling mechanism of a short guide rail type EV-DWPT system. The method and the device are used for solving the problem of unstable system power output caused by a serious mutual inductance drop phenomenon when an emission guide rail in an existing EV-DWPT system is switched. Comprising a plurality of transmitting coils which are sequentially arranged in the X direction and a receiving coil which moves in the X direction and is sequentially coupled with the transmitting coils for electric energy transmission. A plurality of winding wires parallel to the X direction are defined as a longitudinal part of the transmitting coil, a plurality of winding wires parallel to the Y direction are defined as a transverse part of the transmitting coil, the plurality of winding wires of the longitudinal part of the transmitting coil are arranged in a turn-spacing distribution mode, and the plurality of winding wires of the transverse part of the transmitting coil are arranged in a turn-spacing-free tight superposition mode. No magnetic core is added in the transition area so as to weaken the influence of the transverse part of the transmitting coil on mutual inductance of the transmitting end and the receiving end, the structure is simple and efficient, and engineering application is easy.
