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

Abstract

The embodiment of the present invention discloses a microwave field type wireless charging device, wherein the device includes: a housing, a cavity, a microwave signal source, a power amplifier, a transmitting antenna, a partition and a switch button, wherein the cavity has a box-like structure , placed inside the casing, when the cabinet door of the cavity is closed, the casing is used to shield the magnetic field in the cavity; the partitions are arranged inside the cavity in a stepped layered structure, and are used to place the equipment to be charged; the microwave signal source It is placed inside the cavity and is used to convert the electrical signal received by the cavity into a microwave signal when the switch button is triggered; the power amplifier is used to amplify the power of the microwave signal; the transmitting antenna is placed on the inner wall of the cavity for After starting up, the power amplified microwave signal is radiated to the inside of the cavity, and the receiving device of the device to be charged receives the power amplified microwave signal to charge the device to be charged. 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 microwave field type wireless charging device. 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 device to be charged...
