Multi-dimensional rotation type wireless electric transmission device

Abstract

The invention provides a multi-dimensional rotation type wireless electric transmission device. The multi-dimensional rotation type wireless electric transmission device comprises an adjustable-speed rotary electric motor, a wireless electric transmitting rotation repeating coil, a receiving coil and a wireless electric transmitting device power source. The wireless electric transmitting rotation repeating coil supplies power to multiple loads of different positions simultaneously through the rotation mode. The non-contact type energy transmission is carried out by the wireless electric transmitting rotation repeating coil and the receiving coil through a resonant mode. According to the multi-dimensional rotation type wireless electric transmission device, a gap exists between the wireless electric transmitting repeating coil and the receiving coil, and the energy transmission is carried out through the resonance mode. The 360 degree omni-directional rotation is carried out on the rotation repeating coil through the adjustable-speed rotary electric motor. The repeating coil is connected with wireless electric transmitting device power source through an electric conduction link. The rotation repeating coil supplies the power to the multiple loads of the different positions simultaneously through the rotation mode. Due to the fact that the rotation mode is utilized by the rotation repeating coil, the position of the rotation repeating coil can be changed. Based on the resonance principle, the simplest simultaneous power supplying to the multiple loads is achieved, and therefore the practicality is good, the cost is low and the efficiency is high.

[0003] Most of the traditional wireless power transmission devices use inductive wireless power transmission, which is limited by the distance. At the same time, the transmitting coil and the receiving coil must be in a state of facing each other. The application occasions are limited, such as transformers, wireless mobile phone chargers and other traditional methods. Traditional inductive wireless power transmission devices can only transmit energy within a fixed point and direction within a distance of almost contact. If the distance changes or the load position changes, the efficiency of energy transmission will be greatly reduced, which cannot meet the distance requirements. and the power supply situation of loads with changing locations
