Power supplying device, wireless power transmission system and method thereof

A wireless power transmission method, the wireless power transmission method comprising steps as follows:

• detecting a wireless receiving module of at least one power receiving device by a wireless transmission module of at least one power supplying device;
• conducting a gradual searching within a predetermined range by the wireless transmission module to generate signal strength values corresponding to each coordinate point and judging a position of the at least one power receiving device by a highest signal strength value occured within the predetermined range;
• when the wireless receiving module is detected by the wireless transmission module, the at least one power supplying device is electrically and wirelessly connected to the wireless receiving module via the wireless transmission module;
• and
• the at least one power supplying device transmits electric power from the outside supply terminal to the at least one power receiving device;
• wherein a processing module controls a driving module according to the presetting program and the driving module includes a spherical motor for driving the wireless transmission module disposed on a linking-up member to conduct a displacement along a predetermined displacement trajectory within the predetermined range and detect the at least one power receiving device.

A power supplying device, comprising:

• a device main body;
• a driving module being movably configured in the device main body and comprising a spherical motor and a linking-up member;
• a power receiving module, located at the driving module, and receiving electric power from an outside supply terminal;
• a processing module, electrically connected to the power receiving module and connected to the linking-up member of the driving module;
• and
• a wireless transmission module disposed on the processing module, the driving module driving the wireless transmission module to conduct a gradual searching within a predetermined range and signal strength values corresponding to each coordinate point are generated, when a highest signal strength value occurs within the predetermined range, a coordinate point corresponded to the highest signal strength value is judged as a position of at least one power receiving device;
• and
• wherein when the at least one power receiving device is detected by the wireless transmission module within the predetermined range, the processing module accordingly controls the wireless transmission module to electrically and wirelessly connect to the at least one power receiving device, and subsequently, electric power is transmitted to the at least one power receiving device via the wireless transmission module.
