Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] attached figure 1 It is a structural diagram of the wireless energy receiving coil 3, which consists of a base material 31 and a metal wire structure fixed on the base material 31. Its basic structure is similar to that of a PCB antenna. The base material can be an epoxy resin substrate, depending on the application Ceramic substrates can also be used on demand. The difference from PCB antennas is that the metal wire structure includes a feeder 32, a resonant metal coil 33, and a plurality of magnetic microstructures 34. The input end of the feeder 32 is connected to the signal input end of the receiving circuit. The feeder 32 Surrounding the resonant metal coil 33 is used to feed the received signal into the receiving circuit. A plurality of magnetic microstructures 34 are arranged in the central area of ​​the resonant metal coil 33. The magnetic microstructu...

Abstract

The invention provides a wireless energy receiving coil with higher system energy transmission efficiency and a wireless energy transmission system with the wireless energy receiving coil, aiming to overcome the defect that existing resonant wireless energy transmission systems are low in system energy transmission efficiency.

Description

【Technical field】 [0001] The invention relates to the field of wireless energy transmission, in particular to a wireless energy transmission system based on the principle of magnetic resonance. 【Background technique】 [0002] At present, wireless energy transmission technology is mainly based on three principles, namely electromagnetic induction, magnetic resonance and radiation. The basic feature of electromagnetic induction (non-contact inductive) power transmission circuit is the separation of primary and secondary circuits. There is a gap between it and the secondary circuit, which is connected by magnetic field coupling induction. The characteristics of the electromagnetic induction type are: there is a large air gap, so that the primary and secondary sides have no electrical contact, which makes up for the inherent defects of the traditional contact type electric energy; however, the existence of a large air gap also makes the magnetic flux leakage of the system compar...
