Problems solved by technology

[0004] At present, the research on improving the stability of transmission in any space is mostly limited to the two-dimensional plane, and there are many disadvantages in the research results of flexible and stable transmission in three-dimensional space, such as non-coaxial domino resonant coil arrays and self-rotating transmitting coil devices, Although stable power transmission in multiple directions has been achieved, the flexibility and controllability are limited by the large number of relay coils and complex structure, and the stability of transmission in any direction has not been fundamentally improved.

Abstract

The invention discloses a novel wireless electric energy transmission omnidirectional three dimensional transmitting coil apparatus, which takes a three dimensional structure as a bearing mechanism of the transmitting coil. In the three dimensional structure, a plurality of surfaces are selected to place planar spiral coils.

Description

technical field [0001] The invention belongs to the field of wireless power transmission, and in particular relates to a novel limited three-dimensional omnidirectional transmitting coil device for wireless power transmission. Background technique [0002] Since it was discovered in 1840 that the use of electromagnetic induction and wires can transmit electric energy, the transmission of electric energy is mainly carried out by direct contact of wires. The charging of electrical equipment is generally carried out through plugs and sockets, but when high-power charging is performed, there is a risk of high-voltage electric shock in this charging method. And due to the existence of friction and wear, the safety, reliability and service life of the system are low, especially in some flammable and explosive fields such as chemical industry and mining, which can easily cause major accidents. The new contactless power transmission system adopts the principle of electromagnetic in...
