Problems solved by technology

[0002] At present, most electronic devices use wired charging. The disadvantage is that the charging process relies on cables, and there is a risk of wire contact and frictional discharge. The voltage platform and charging interface are different, resulting in a complicated charging process and low charging efficiency.
This will lead to low charging efficiency, and the charging environment is exposed to free space, and the safety cannot be guaranteed

Embodiment 1

[0084] see figure 1 , figure 1 It is a schematic structural diagram of a microwave field type wireless charging device provided by an embodiment of the present invention. like figure 1 As shown, the device includes a casing 1, a cavity 2, a microwave signal source ( figure 1 not shown), power amplifier ( figure 1 not shown in), the transmitting antenna 3, the partition plate and the switch button 5 placed on the surface of the casing 1, the position acquisition module ( figure 1 not shown in) and the control module ( figure 1 not shown), wherein,

[0085] The cavity 2 has a box-type structure and is placed inside the casing 1 . When the cabinet door of the cavity 2 is closed, the casing 1 is used to shield the magnetic field in the cavity 2 . Wherein, the casing may be made of metal. The interior of the cavity is designed without edges and corners, that is, the circumference of the cavity and the contact points of the partition are rounded.

[0086] The separator is ar...

Embodiment 2

[0123] see Figure 8 , Figure 8 It is a schematic flowchart of a microwave field type wireless charging control method provided by an embodiment of the present invention. The method is applied to the charging process of the above-mentioned microwave field type wireless charging device, and can be executed by a control module in the microwave field type wireless charging device. like Figure 8 As shown, the charging control method provided by this embodiment specifically includes:

Abstract

The embodiment of the present invention discloses a microwave field type wireless charging control method, wherein the method includes: receiving the position data of each device to be charged, and controlling the start of the transmitting antenna at the corresponding position according to the position data; wherein the transmitting The antenna includes a plurality of antenna array elements arranged in an array form; determining the weight of each antenna array element in the activated transmitting antenna; controlling each antenna array element to radiate microwave signals according to the corresponding weight according to the weight. By adopting the above technical solution, the charging efficiency is improved while ensuring the charging safety.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless charging, and in particular, to a method for controlling microwave field-type wireless charging. Background technique [0002] At present, most electronic devices use wired charging. The disadvantage is that the charging process relies on cables, there is the danger of wire contact and frictional discharge, and the voltage platform and charging interface are different, resulting in complicated charging process and low charging efficiency. The wireless charging realizes the energy transmission between the power supply and the electrical equipment in a non-contact wireless way. The emergence of wireless charging technology makes up for the defects of wired charging. [0003] In the current microwave wireless charging products, when the microwave energy transmission method is used for wireless charging, the antenna array can only be activated at the same time to charge the devi...
