Magnetic resonance wireless charging system for prolonging transverse coupling distance of transmitting and receiving antenna

Abstract

The invention discloses a magnetic resonance wireless charging system for prolonging the transverse coupling distance of a transmitting antenna and a receiving antenna. The magnetic resonance wireless charging system comprises the transmitting antenna, a relay coupling coil and the receiving antenna. The transmitting antenna is used for transmitting wireless electric energy and performing magnetic resonance coupling with the relay coupling coil to form radio frequency current on the relay coupling coil; the relay coupling coil is used for increasing the transverse coupling distance between the transmitting antenna and the receiving antenna, and a uniformly distributed magnetic field is formed around the relay coupling coil through radio frequency current generated by resonance coupling of the relay coupling coil and the transmitting coil; the receiving antenna is used for coupling energy in a magnetic field around the relay coupling coil. A stable and efficient wireless charging or wireless power supply scheme is provided for electronic equipment such as portable computers, communication products, consumer electronics, LED lighting equipment and the like.

Description

technical field [0001] The invention belongs to the technical field of wireless energy transmission, and in particular relates to a magnetic resonance wireless charging system for extending the transverse coupling distance of a transceiver antenna. Background technique [0002] With the continuous development of electronic information technology and automation control technology, various home appliances, consumer electronics, mobile communication equipment, etc. have been widely popularized. However, traditional household appliances rely Electronic devices with built-in batteries also need a wired connection between the charging cable and the power outlet for charging, so we can see wires that provide power supply for these electronic devices everywhere. These wires not only occupy our activity space, limit the convenience of equipment use, but also create hidden dangers for safe use of electricity. Therefore, with the growing demand for portable devices and green energy sy...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the transmission efficiency between the transceiver antennas is poor as the distance between the transceiver antennas increases within a certain range when the transceiver antennas are side by side on the same plane, and proposes a method for extending the transverse coupling of the transceiver antennas.
