Abstract

A wireless transmitting device for wireless charging includes a main body, a first encapsulated transmission coil and a second encapsulated transmission coil. The first encapsulated transmission coil and the second encapsulated transmission coil are disposed in the main body, and the second encapsulated transmission coil is adjacent to the first encapsulated transmission coil. Each of the first encapsulated transmission coil and the second encapsulated transmission coil has a quadrangular winding configuration so that the magnetic flux generated at the short-side section of the first or second encapsulated transmission coil is greater than the magnetic flux generated by an encapsulated transmission coil having a circular winding configuration. Therefore, the wireless charging range of the wireless transmitting device for wireless charging is improved.

Dependent claims

A wireless transmitting device for wireless charging by transmitting a power to an encapsulated receiving coil of an electronic device, the wireless transmitting device comprising:

a main body;
a first encapsulated transmission coil disposed in the main body and close to a side of the main body, being selectively conducted to generate an electromagnetic effect and transmit the power to the encapsulated receiving coil in response to the electromagnetic effect;
a second encapsulated transmission coil disposed in the main body and adjacent to the first encapsulated transmission coil, being selectively conducted to generate the electromagnetic effect and transmit the power to the encapsulated receiving coil in response to the electromagnetic effect;
wherein the first encapsulated transmission coil has a quadrangular winding configuration, and the second encapsulated transmission coil has the quadrangular winding configuration.
