Problems solved by technology

At present, some wireless charging devices use a wireless charging platform based on inductive coupling. The disadvantage is that the receiving coil and the transmitting coil cannot be separated, and the energy transmission distance is relatively short.
Some wireless charging devices use anti-parallel coils to overcome the problem of reduced transmission efficiency due to distance changes, but the coil structure must be coaxial with the receiving coil and the transmitting coil, and the spatial area for stable energy transmission is small

Abstract

The invention discloses wireless charging equipment. The charging equipment comprises a power supply circuit and at least two parallel and coaxially arranged Helmholtz coils, wherein the two Helmholtz coils are coupled to the power supply circuit, the Helmholtz coils are a first coil and a second coil respectively, and after electrification, uniform magnetic field areas exist between the first coil and the second coil; if the first coil and the second coil are circular coils, the first coil and the second coil have the same number of turns and radius, and the distance between the first coil and the second coil is identical to the radius; if the first coil and the second coil are square coils, the first coil and the second coil have the same number of turns and side length, and the distance between the first coil and the second coil is 0.5445 time of the side length. Through the method, the wireless charging equipment can improve stability of wireless energy transmission in a certain space region.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a wireless charging device. Background technique [0002] Wireless charging equipment has gradually begun to enter all aspects of people's daily life, especially restricted by the development of battery technology, the emergence of wireless charging has brought earth-shaking changes to people's production and life. At present, some wireless charging devices use a wireless charging platform based on inductive coupling. The disadvantage is that the receiving coil and the transmitting coil cannot be separated, and the energy transmission distance is relatively short. Some wireless charging devices use anti-parallel coils to overcome the problem of reduced transmission efficiency due to distance changes, but the coil structure must be coaxial with the receiving coil and the transmitting coil, and the spatial area for stable energy transmission is small.
