The invention relates to a wireless energy receiving device and a multistage guide rail type wireless energy transmission system. The wireless energy receiving device comprises a pickup coil, a relay coil and a magnetic shielding layer, and the relay coil comprises a first sub-coil and a second sub-coil; the first sub-coil and the second sub-coil are electrically connected in series and located on the two sides of the magnetic shielding layer respectively, the first sub-coil is used for being coupled with the energy transmitting coil to achieve wireless energy pickup, and the second sub-coil is used for being coupled with the pickup coil and transmitting the picked energy to the pickup coil to supply power to a load. The invention has the beneficial effects that the receiving device is provided with the relay coil, the relay coil is wound in a layered mode, magnetic isolation of the pickup coil and the transmitting coil is effectively achieved through the magnetic shielding layer, and the relay coil and the pickup coil can form a double-S topological structure which can be matched with a transmitting end multi-S topology to form a multi-stage guide rail type wireless energy transmission system; therefore, the constant-voltage output characteristic of the receiving end is effectively maintained, the number of components is reduced, the system structure is simplified, and the design cost is saved.
