A wireless power reception device can include a first shielding member; a second shielding member; a short-range communication coil on the first shielding member; a wireless charging coil on the second shielding member; and a hole outside the wireless charging coil, in which the hole penetrates through the first shielding member.

Wireless power reception device

A wireless power reception device can include a first shielding member; a mounting member on the first shielding member; a short-range communication coil on the mounting member; a second shielding member inside the short-range communication coil; a wireless charging coil inside the short-range communication coil; and an alignment hole outside the wireless charging coil, in which the alignment hole penetrates through the first shielding member and the mounting member.

A wireless power reception device includes an inner coil, a mounting member having the inner coil mounted thereon and a slit formed in an edge of the inner coil, and a first shielding member and a second shielding member laminated on the first shielding member and provided in correspondence with the inner coil, the mounting member being mounted on the first shielding member and the second shielding member. Accordingly, it is possible to improve efficiency of the wireless power reception device.

Disclosed is a wireless power transmitter. The wireless power transmitter for transmitting power to a wireless power receiver in a wireless scheme, includes a transmission circuit unit converting power supplied from a power supply unit into power having a frequency for resonance; a transmission induction coil coupling the converted power; and a transmission resonance coil disposed adjacent to the transmission induction coil to transfer the coupled power from the transmission induction coil to the wireless power receiver using the resonance, wherein the transmission circuit unit is vertically spaced apart from the transmission resonance coil.
