Non-contact charging module and reception-side and transmission-side non-contact charging apparatuses using the same

A transmission-side non-contact charging module that transmits power to a reception-side non-contact charging module that comprises a first hole by an electromagnetic induction and that is allowed to align with the reception-side non-contact charging module in either a first case or a second case, the first case being a case where a magnet included within the first hole in the reception-side non-contact charging module is used when alignment with the reception-side non-contact charging module is performed, the second case being a case where the magnet is not within the first hole and thereby not used when the alignment is performed, the transmission-side non-contact charging module comprising:

• a planar coil portion in which a conducting wire is wound and that comprises a second hole of a predetermined size, the second hole being provided within an inner winding of the planar coil portion;
• and
• a ferrite sheet on which a coil surface of the planar coil portion is placed and that faces the coil surface of the planar coil portion and that attracts, in the case where the magnet is used when the alignment with the reception-side non-contact charging module is performed, the magnet of the reception-side non-contact charging module,
• wherein the predetermined size of the second hole is larger than a size of the magnet included in the reception-side non-contact charging module, and
• wherein the predetermined size of the second hole is greater than 15.5 mm.

A reception-side non-contact charging module that receives power from a transmission-side non-contact charging module that comprises a first hole by an electromagnetic induction and that is allowed to align with the transmission-side non-contact charging module in either a first case or a second case, the first case being a case where a magnet included within the first hole in the transmission-side non-contact charging module is used when alignment with the transmission-side non-contact charging module is performed, the second case being a case where the magnet is not within the first hole and thereby not used when the alignment is performed, the reception-side contact charging module comprising:

• a planar coil portion in which a conducting wire is wound in a spiral shape and comprises a second hole of a predetermined size, the second hole being provided within an inner winding of the planar coil portion;
• and
• a magnetic sheet on which a coil surface of the planar coil portion is placed and that faces the coil surface of the planar coil portion and that attracts, in the case where the magnet is used when the alignment with the transmission-side non-contact charging module is performed, the magnet of the transmission-side non-contact charging module, wherein
• an inner diameter of the planar coil portion is larger than the magnet included in the transmission-side non-contact charging module, and
• the predetermined size of the second hole is greater than 15.5 mm.

A non-contact charging module that performs power transmission by an electromagnetic induction with another non-contact charging module that comprises a first hole and that is allowed to align with the other non-contact charging module in either a first case or a second case, the first case being a case where a magnet included within the first hole in the other non-contact charging module is used when alignment with the other non-contact charging module is performed, the second case being a case where the magnet is not within the first hole and thereby not used when the alignment is performed, the non-contact charging module comprising:

• a planar coil portion in which a conducting wire is wound in a substantially rectangular shape and that comprises a second hole of a predetermined size, the second hole being provided within an inner winding of the planar coil portion;
• and
• a magnetic sheet on which a coil surface of the planar coil portion is placed and that faces the coil surface of the planar coil portion, wherein
• the predetermined size of the second hole is at least equal to a size of the first hole, and
• the predetermined size of the second hole is greater than 15.5 mm.
