Embodiment Construction

[0024] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 As shown, the wireless charging method based on shared aperture multi-beamforming disclosed in the present invention includes the following steps:

[0026] (1) Arranging an array of charging equipment, the array of charging equipment is a cube, including 5 fronts, and the 5 fronts are 5 sides of the cube; each array is arranged with the same number of array elements, and each front is The array elements on are arranged at equal intervals in the horizontal direction and the vertical direction;

[0027] (2) Divide each array into two sub-arrays with the same number of array elements, one of which generates two low-frequency beams, and the other generates two high-frequency beams, and uses the first harmonic component of the time modulation array and The negative first harmonic component performs beamforming, which specif...

Abstract

The invention discloses a shared aperture multi-beamforming-based wireless charging method. The method includes the following steps that: 1, a charging device array is arranged, wherein the charging device array is cubic and comprises five array planes, the same number of array elements being arranged on each array plane; 2, each array plane is divided into two sub-arrays with the same number of array elements, wherein the two sub-arrays are respectively used for generating two low-frequency wave beams and two high-frequency wave beams; 3, wireless connections are built between charged devicesand the charging devices, array planes and a resonant frequency which cover the charged devices are determined, wave beams in each array plane are sequenced according to the number of charged deviceswhich are covered by the wave beams, wave beams covering the most charged devices in each array plane are determined as the radiation wave beams of the corresponding array plane; and 4, the charged devices are charged, and energy transfer is carried out under the resonant frequency. With the method adopted, the efficiency problem of the charging of a plurality of charged devices under a conditionthat the number of the charged devices is much larger than the number of charging devices can be solved.

Description

technical field [0001] The invention belongs to the field of wireless charging, and in particular relates to a wireless charging method based on shared aperture multi-beam forming. Background technique [0002] In February 2017, Apple announced to join the Wireless Charging Alliance, and believed that wireless charging must be a trend in the future. In September of the same year, Apple launched a charging device that can support wireless charging of iPhone 8 and other series products at the press conference. At the same time, with the continuous development of multi-beam technology, multi-beam technology can be applied to wireless charging, which can further improve the charging efficiency of the charged device. How to efficiently solve the charging efficiency of multiple charged devices, especially when the number of charged devices is much larger than the number of charging devices and the number of beams, there is currently no effective method.
