Dual-cross coil array-type magnetic resonant coupling wireless electric energy transmission coil structure

Abstract

The invention discloses a dual-cross coil array-type magnetic resonant coupling wireless electric energy transmission coil structure. The dual-cross coil array-type magnetic resonant coupling wirelesselectric energy transmission coil structure comprises an emission module and a receiving module, wherein the emission module is used for emitting wireless electric energy, the receiving module is used for receiving the wireless electric energy, the emission module is designed by horizontally arranging two cross coils in an array way, the coils are not overlapped, so that the transmission efficiency of a receiving coil at different transverse and longitudinal positions in an emission coil region is equalized, and the wireless charging and power supply requirement of a plurality of electronic equipment can be met. On the basis of magnetic resonant coupling wireless energy transmission scheme, the coil structure of a transceiving module is processed by a planar printed circuit, the miniaturization and the integration of a system are achieved, the production, installation and maintenance cost of the system is greatly reduced, and a stable and high-efficiency wireless charging or wirelesselectric energy supply scheme is provided for a portable computer, a communication product, a consumer electronic product and LED lighting equipment.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to the design of a double cross coil array type magnetic resonance coupling wireless power transmission coil structure. 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 syste...
