Abstract
The invention relates to a radio induction charging device for a portable communication apparatus, which comprises an electric core, a radio electric energy induction coil, a magnetic shielding material and an electric core / radio induction charging circuit dual-function protective board, wherein the electric core is used for storing electric energy; the radio electric energy induction coil is used for collecting magnetic fields to generate and output electric energy to a dual-function electric core protective board; the magnetic shielding material is positioned between the electric core and the radio induction coil, and mainly used for insulating radio electromagnetic waves; and the electric core / radio induction charging circuit dual-function protective board is used for safely inputting the electric energy into the electric core. By using the invention, new and old portable apparatuses are compatible to use the radio charging function, so that the radio induction charging interfaces are unified, thereby avoiding great waste of batteries, and ensuring that batteries with the same capacity volume of all the portable apparatuses are completely universal.
Description
technical field [0001] The invention relates to a wireless induction charging device, in particular to a wireless induction charging receiving device of a portable communication device. Background technique [0002] At present, wireless transmission technology is mainly divided into three types: electromagnetic induction, radio wave, and electromagnetic resonance. Regardless of which technology, the cornerstone of its realization comes from the theory of electromagnetic induction discovered by Michael Faraday in 1831, and the concept of wireless power transmission established by Nikola Tesla in 1890. Wireless charging technology mainly uses electromagnetic technology to convert current into electromagnetic in the transmitter, and convert electromagnetic into rated voltage and current through a specific built-in chip receiver to charge electronic products. [0003] Wireless charging technology has been mostly used in professional fields before, where products need to be seal...
