Abstract

The invention provides a magnetic coupling transmission system, comprising a receiving coil arranged in a receiving device housing, a transmitting coil arranged in the transmitting device housing anda protective housing internally provided with a magnetic line of force aggregate, wherein the protective housing is located between the receiving device housing and the transmitting device housing; Amagnetic line of force aggregate is use to provide the path with the highest permeability between the transmit coil and the receive coil, so as to guide the magnetic lines of force generated by the transmitting coil to preferentially pass through the magnetic field line aggregate and then through the receiving coil, or to guide the magnetic lines of force generated by the transmitting coil moduleto preferentially pass through the receiving coil module and then through the magnetic field line aggregate module to return from the magnetic line of force aggregate module to the transmitting coil module. The invention can improve the density of magnetic lines of force passing through the receiving coil in the wireless charging process, so that when the distance between the receiving coil and the transmitting coil is long and the output power of the transmitting end is constant, the receiving power of the receiving end is not significantly reduced.

Description

technical field [0001] The invention relates to the field of wireless power transmission, in particular to a magnetic coupling transmission system capable of maintaining high power efficiency when the distance between the receiving coil module and the transmitting coil module is relatively long. Background technique [0002] With the development of wireless charging technology, wireless charging devices / receiving devices have been widely used in the energy supply of various mobile electric devices. At present, in commonly used wireless charging schemes, the magnetic coupling distance between the receiving coil module in the housing of the receiving device of a mobile phone and the transmitting coil module in the housing of the transmitting device cannot be too far, generally not exceeding 5 mm or the maximum distance of the transmitting coil module Outer dimension . Otherwise, when the output power of the transmitting device is constant, with the increase of the magnetic ...
