Wireless power transfer module for vehicles

A wireless power transmission module for a vehicle comprising:

• a housing providing an internal space and including an upper plate on which a portable device to be charged is placed;
• an antenna unit including a first wireless power transmission antenna operating in a magnetic induction method and a second wireless power transmission antenna operating in a magnetic resonance method;
• and
• a shielding unit including a first shielding sheet disposed in an area corresponding to the first wireless power transmission antenna and a second shielding sheet disposed in an area corresponding to the second wireless power transmission antenna;
• wherein the antenna unit is placed inside the housing so that a first distance from the first wireless power transmission antenna to an outer surface of the upper plate is shorter than a second distance from a second wireless power transmission antenna to an outer surface of the upper plate,
• wherein the first distance is set so that a coupling coefficient k between a reception coil included in the portable device and the first wireless power transmission antenna is 0.7 or more, and the second distance is set so that a coupling coefficient k between the reception coil included in the portable device and the second wireless power transmission antenna is less than 0.2.
