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.

    本发明涉及一种无线能量接收装置及多级导轨式无线能量传输系统,无线能量接收装置包括拾取线圈、中继线圈和磁屏蔽层,中继线圈包括第一子线圈和第二子线圈;第一子线圈和第二子线圈电性串联并分别位于磁屏蔽层的两侧,第一子线圈用于耦合能量发射线圈实现无线能量拾取,第二子线圈用于耦合拾取线圈并将拾取的能量传递至拾取线圈为负载供电。其效果是:接收装置自带中继线圈,且中继线圈分层绕制,通过磁屏蔽层有效实现拾取线圈和发射线圈的磁隔离,中继线圈和拾取线圈能够形成双S拓扑结构,可以配合发射端多S拓扑构成多级导轨式无线能量传输系统,从而有效保持接收端恒压输出特性,节省元器件数量,简化系统结构,节约设计成本。
