First Claim
Patent Images
1. A slot-type induction charger, comprising:
- power base comprising a base member defining therein a slot, a control module mounted in said slot of said base member and a power-supplying coil module mounted in said slot of said base member and electrically coupled to said control module for creating oscillation to emit an electric energy, said power-supplying coil module comprising a power-supplying magnetic conductor, a plurality of first power-supplying coils and at least one second power-supplying coil respectively wound round said power-supplying magnetic conductor in reversed directions, each said second power-supplying coil being electrically connected in series between two said first power-supplying coils, and a power-supplying induction zone defined between each said second power-supplying coil and each adjacent said first power-supplying coil; and
least one induction charging receiver settable in said slot of said base member of said power base for receiving said electric energy from said power-supplying coil module by electromagnetic induction for charging an electromagnetic device, each said induction charging receiver comprising an expansion base, a charging module mounted in said expansion base and a power-receiving coil module mounted in said expansion base and electrically coupled to said charging module and adapted for receiving an electric energy induced by said power-supplying coil module by means of electromagnetic induction, said expansion base comprising an electric connector for the connection of an electromechanical device to be charged, said power-receiving coil module comprising a power-receiving magnetic conductor, a plurality of first power-receiving coils and at least one second power-receiving coil wound round said power- magnetic conductor in reversed directions, each said second power-receiving coil being electrically connected in series between two said first power-receiving coils, and a power-receiving induction zone defined between each said second power-receiving coil and each adjacent said first power-receiving coil.

Abstract
A slot-type induction charger having light, thin, short and small characteristics is disclosed to include a power base holding therein a control module and a power-supplying coil module in a base member thereof for inducing an electric current, and an induction charging receiver set in the base member for receiving the induced electric current by electromagnetic induction from the power base for charging an electromagnetic device being connected to an electrical connector thereof. The power-supplying coil module and the power-receiving coil module each includes a magnetic conductor and a series of coils being alternatively and reversely wound around the magnetic conductor.
