Abstract

The invention discloses a three-dimensional polyhedral magnetic resonance wireless charging transmission device based on multi-antenna switching. The three-dimensional polyhedral magnetic resonance wireless charging transmission device comprises a magnetic resonance wireless electric energy transmitting module, a plurality of magnetic resonance transmitting antennas, a plurality of receiving antennas and a magnetic resonance wireless electric energy receiving module which are connected in sequence, the magnetic resonance wireless electric energy transmitting module is used for converting a direct-current power supply into the radio frequency energy and controlling a working mode; the magnetic resonance transmitting antenna is used for converting the radio frequency energy into a reactance field distributed in space; the receiving antenna is used for converting the reactance field into the radio frequency energy; and the magnetic resonance wireless electric energy receiving module is used for converting the radio frequency energy into a direct current power and charging or supplying power to a load. According to the present invention, the transmitting antennas are multiple groups of antennas, when one antenna is used as a main transmitting antenna, other antennas are used as relay coupling antennas, the transmitting and receiving antennas all adopt a three-dimensional multi-layer winding structure, the size difference of the transmitting and receiving antennas is larger, and the antenna is suitable for charging and supplying power to a micro device which is limited in cruising ability and cannot be supplied with power in a wired manner.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to a three-dimensional polyhedron magnetic resonance wireless charging transmission device based on multi-antenna switching. Background technique [0002] With the continuous development of electronic information technology and automation control technology, various electronic devices such as small consumer electronics products, Internet of Things sensors, industrial sensors and miniature medical equipment are becoming more and more popular. However, most of these devices still rely on power supply The wired connection between the cable and the power socket is used to achieve charging. The physical connection of the charging cable limits the convenience of using this type of equipment, and the existence of the charging port has become a design bottleneck for the further miniaturization of this type of equipment. In addition, through the plug-in The me...
