Title:
WIRELESS CHARGING ANTI-OFFSET COUPLING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2022/237067
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of wireless power transfer, and specifically relates to a wireless charging anti-offset coupling mechanism. The wireless charging anti-offset coupling mechanism comprises a transmitting-end mechanism and a receiving-end mechanism, wherein the transmitting-end mechanism comprises an energy transmitting coil and a transmitting-end resonant compensation network, and the transmitting-end resonant compensation network comprises a transmitting-end compensation coil; and the receiving-end mechanism comprises an energy receiving coil and a receiving-end resonant compensation network, and the receiving-end resonant compensation network comprises a receiving-end compensation coil. By means of the present invention, a compensation inductor is integrated into an energy transfer coil without mutual interference therebetween, and even if relative positions of an energy transmitting coil and an energy receiving coil have a certain offset and are not fully aligned, the function of transmitting energy by the energy transmitting coil to the energy receiving coil can also be well achieved, such that the anti-offset capability of the coupling mechanism is improved, and a system characteristic basically remains unchanged within a certain offset range; and the compensation inductor and the energy transfer coil are decoupled from each other, such that the problem of mutual interference therebetween is solved, thereby ensuring the constant-current output characteristic of a topology.
