Anti-offset Coupling Mechanism for Wireless Power Transmission

Abstract

The invention discloses an anti-deviation coupling mechanism for wireless energy transmission, which includes a transmitting end and a receiving end; the transmitting end includes a horizontal plane spiral coil and two inclined plane spiral coils, and the two inclined plane spiral coils are respectively located On both sides of the coil, the inclined plane spiral coil is tangent to the horizontal plane spiral coil, and the tangent point between the two inclined plane spiral coils and the horizontal plane spiral coil is on a straight line with the center starting point of the horizontal plane spiral coil; the receiving end Arranged opposite to the transmitter. By setting an appropriate angle θ, even if there is a certain offset distance between the receiving end and the transmitting end, the planar spiral coils at both ends are still in alignment, and a magnetic coupling coil with a high coupling coefficient can be produced according to requirements. It can also achieve good transmission performance even when the transmitting end and the receiving end are misaligned, and has the advantage of flexibly meeting transmission requirements.

Description

Anti-offset coupling mechanism for wireless power transfer technical field The present invention relates to the technical field of wireless power transmission, be specifically related to a kind of anti-offset coupling machine of wireless power transmission structure. Background technique Wireless power transfer technology is one of the relatively new power transfer technologies at present, which converts electrical energy into other energy. Quantity is transported over a certain distance by utilizing a soft medium in space and is converted into electrical energy again. It is green, safe and Non-contact features. At present, wireless power transfer technology is used to get rid of material medium, it has a wide range of applications in many fields applications such as electric vehicle charging, implantable device charging, smart home and wireless sensor networks. [0003] Typically, energy is transferred from a transmitter coil to a receiver coil, and the two coils ...

AI Technical Summary

Problems solved by technology

However, in practice, due to the separation of the transmitting end and the receiving end of the wireless power transfer system, it is easy to misalign the coils when the object moves, or they cannot be placed very precisely.

In addition, coil misalignment can greatly reduce the transmission efficiency and cause system instability, which cannot be tolerated in practice
