A coil module is provided, including a second coil mechanism. The second coil mechanism includes a third coil assembly and a second base corresponding to the third coil assembly. The second base has a positioning assembly corresponding to a first coil mechanism.

Coil module

A magnetic conductive substrate is provided and is used for wireless charging or wireless communication. The magnetic conductive substrate includes a first magnetic conductive layer, a second magnetic conductive layer, and a third magnetic conductive layer. The first magnetic conductive layer has a first magnetic permeability, the second magnetic conductive layer has a second magnetic permeability, and the third magnetic conductive layer has a third magnetic permeability. The second magnetic conductive layer is disposed between the first magnetic conductive layer and the third magnetic conductive layer, the first magnetic permeability is different from the second magnetic permeability, and the second magnetic permeability is different from the third magnetic permeability.

Magnetic conductive substrate and coil assembly

A wireless device is provided, and the wireless device includes a first magnetic conductive plate, a second magnetic conductive plate and a coil assembly. The second magnetic conductive plate is disposed on the first magnetic conductive plate. The coil assembly is disposed on the second magnetic conductive plate. The coil assembly includes a starting end and a terminating end, and the coil assembly is wound around a winding axis to form a spiral structure. The terminating end is located outside of the spiral structure. The coil assembly includes at least three metal wires which are arranged parallel to each other along the second magnetic conductive plate and are connected to each other in parallel at the starting end and the terminating end.

Wireless device

A wireless charging device includes a transmitting-end ferrite core and a transmitting-end coil, wherein the transmitting-end ferrite core have a bottom plate and two upright plates for forming a U-shaped structure defining a charging space therein. One or more wireless power receiving apparatus is put in the charging space. The wireless power receiving apparatus includes a receiving-end coil and a receiving-end ferrite plate, wherein the receiving-end ferrite plate is vertical to the two upright plates. When electrical current flows through the transmitting-end coil to generate an electromagnetic field in the charging space, the electromagnetic field via the two upright plates goes through each of the receiving-end ferrite plates to form an electromagnetic loop. Each of the receiving-end coils generates a charging electrical current induced by the electromagnetic field. Therefore, the present invention can achieve wireless charging to more than one wireless power receiving apparatus at the same time.
