Embodiment Construction

[0037] In the prior art, the far-field wireless communication technology is based on a radio frequency system, and charges devices through radio frequency waves, mainly including Wattup technology and Cota technology. Wattup technology uses 5.8GHz radio waves to transmit power, while Cota technology uses 2.4GHz radio waves to transmit power. In practical applications, it is known that in different wireless environments, the attenuation speed of radio waves of some frequencies is relatively fast. If only a single frequency radio wave is used to transmit electric energy, in some special application scenarios, the radio wave attenuation speed is faster, resulting in low charging efficiency, or even failure to charge.

[0038]In the embodiment of the present invention, the radio frequency transmitting end simultaneously generates radio frequency waves of different frequencies. The radio frequency receiving end can receive the radio frequency electric wave of the corresponding fre...

Abstract

The invention discloses a wireless charging system and a radio frequency receiving terminal. The wireless charging system comprises a radio frequency transmitting terminal and the radio frequency receiving terminal, wherein the radio frequency transmitting terminal is suitable for generating and transmitting radio frequency waves of different frequencies at the same time; and the radio frequency receiving terminal is coupled to the radio frequency transmitting terminal and preset to-be-charged equipment separately and is suitable for receiving the radio frequency waves of corresponding frequencies transmitted from the radio frequency transmitting terminal and converting the received radio frequency waves into electric energy. According to the wireless charging system and the radio frequency receiving terminal, the robustness of the wireless charging system can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charging system and a radio frequency receiving end. Background technique [0002] With the continuous development of the electronics industry, more and more manufacturers pay attention to wireless charging technology. When charging, there is no need to use a charging wire to connect with the electronic product, which can bring better user experience to the user. [0003] Wireless charging technology can generally include near-field wireless charging technology and far-field wireless charging technology, near-field wireless communication technology includes magnetic induction wireless charging and magnetic resonance wireless charging, and the charging range is small, only a few millimeters to tens of centimeters. Far-field wireless communication technology has a large charging range, which can reach several meters or even more than ten meters. [0004] The ...
