A low-frequency penetration-type power transmission apparatus capable of penetrating through a metal medium to wirelessly transmit electric power. The apparatus comprises a transmitter (10), a separator (30), and a receiver (20). The transmitter (10) is configured to convert direct-current electric energy into alternating-current magnetic energy with a preset frequency, and output to the outside through a preset port. The separator (30) is made of preset metal or metal alloy, and is set to a preset form. The receiver (20) is configured to be separated in the separator (30) by a preset reception port and is connected to the reception port when the receiver (20) is in a use stage, receive the alternating-current magnetic energy in a manner of magnetic field coupling or electromagnetic resonance, and then convert the alternating-current magnetic energy into direct-current electric energy. The low-frequency penetration-type power transmission apparatus can meet requirements for wireless charging of a mobile phones with a metal back housing, and can also be widely used in other application projects in which the driving electric power needs to be transmitted in a wireless sensing manner by penetrating through a metal apparatus or a metal part. |
