Abstract:
Provided is a magnetic field shielding module for an electric vehicle. The magnetic field shielding module for an electric vehicle according to an embodiment of the present invention is utilized in a wireless power transmission module for an electric vehicle, and comprises: a shielding layer including a plurality of unit blocks which are made of ferrite materials so as to be able to block a magnetic field generated from a flat coil in which a conductive member is wound multiple times; and a coil accommodation groove recessed to a certain depth from one surface of the shielding layer so as to be able to accommodate the thickness of the flat coil. The shielding layer is formed in a plate shape having a certain area by arranging the plurality of unit blocks adjacent to each other. At least some of the plurality of unit blocks include unit accommodation grooves for accommodating a portion of the flat coil, and the unit accommodation grooves respectively formed in the at least some of the unit blocks may be connected to each other in a state in which the plurality of unit blocks are arranged adjacent to each other, and thereby form the coil accommodation groove having a shape corresponding to the flat coil.
