Fig. 1 is a schematic structural diagram of a wireless charge receiving device according to an embodiment of the present application, and as shown in fig. 1, the wireless charge receiving device includes: a receiving antenna array 10, a plurality of rectifying circuits 20, a battery 30 and a power combining circuit 40.

In an embodiment of the present application, the receiving antenna array 10 may be formed by a plurality of receiving antennas 11 operating at the same frequency according to a certain arrangement sequence, and the receiving antennas 11 may be any one of a magnetoelectric dipole antenna, a high-gain dipole antenna, and a patch antenna, and have a higher receiving gain compared with a common receiving antenna, so that after the receiving antennas 11 are arranged as the receiving antenna array 10, the receiving antenna array 10 has a higher receiving power, and it can be understood that after the receiving power of the wireless charging receiving device is increased, more signals can be received in a unit time, and thus, the wireless charging speed and the signal conversion rate are increased.
In specific application, the receiving antenna 11 firstly receives the radio frequency signal transmitted by the wireless charging transmitting device. The wireless charging transmitting device may be various chargers having a function of transmitting radio frequency signals, and it should be understood that the radio frequency signals are electromagnetic waves having energy, so that the wireless charging transmitting device transmits energy by transmitting the radio frequency signals, and the receiving antenna 11 receives the radio frequency signals, thereby facilitating subsequent charging of the battery 30 by the radio frequency energy.
In an embodiment of the present application, the radio frequency signal received by the receiving antenna 11 may be a millimeter wave, and the millimeter wave has a wider spectrum bandwidth and a higher transmission rate, and a narrower beam has a good propagation directivity, so the wireless charging receiving device of the embodiment of the present application charges by receiving energy in the millimeter wave, can improve the wireless charging speed, and is favorable for the directivity of wireless charging.
Further, the receiving antenna 11 sends the received radio frequency signal to the corresponding rectifying circuits 20, and each rectifying circuit 20 converts the received radio frequency signal into a direct current signal, so that radio frequency energy is converted into direct current, and collection of the radio frequency energy is realized. As a possible implementation manner, the rectifier circuit 20 in the embodiment of the present application may include an impedance matching unit 21 and a rectifier diode 22, and after the impedance matching unit 21 performs impedance transformation on the radio frequency signal, the rectifier diode 22 performs signal conversion, where the rectifier diode 22 may operate in multiple frequency bands, so as to implement multi-frequency rectification and improve the conversion rate of the radio frequency signal.
Further, each of the rectifier circuits 20 sends the converted dc signal to the power combining circuit 40, the power combining circuit 40 combines the received multiple paths of dc signals, combines the multiple paths of dc signals into one path of dc signal with a higher signal strength, outputs the combined dc signal to the battery 30, and charges the battery 30 by converting the combined dc signal.
Therefore, the wireless charging receiving device provided by the embodiment of the invention receives the radio frequency signal through the receiving antenna array, improves the signal receiving power, converts the radio frequency signal into the direct current signal through the rectifying circuit to charge the battery, and improves the energy conversion rate of wireless charging compared with an electromagnetic induction type charger.

Based on the above embodiment, in order to further improve the wireless charging efficiency of the wireless charging receiving device, a specific wireless charging receiving device is further provided in the embodiment of the present application, and fig. 2 is a schematic structural diagram of the specific wireless charging receiving device provided in the embodiment of the present application.
As shown in fig. 2, the wireless charge receiving apparatus further includes, on the basis of fig. 1: a plurality of matching circuits 50, a plurality of first phase shifters 60, and a filter circuit 70.
A first end of each matching circuit 50 is connected to the corresponding receiving antenna 11, a second end of each matching circuit 50 is connected to a first end of the corresponding first phase shifter 60, a second end of each first phase shifter 60 is connected to the corresponding rectifying circuit 20, a first end of the filter circuit 70 is connected to a second end of the power combining circuit 40, and a second end of the filter circuit 70 is connected to the battery.
The matching circuit 50 is configured to match impedances of the receiving antenna 11 and the rest of the wireless charging receiving apparatus, and it can be understood that, after the receiving antenna 11 is impedance-matched with the rest of the wireless charging receiving apparatus, the receiving antenna 11 can transmit the received radio frequency signal in a working state of maximum power output, thereby further increasing the wireless charging speed.
Further, the matching circuit 50 sends the radio frequency signal received by the receiving antenna 11 to the corresponding first phase shifter 60, and when the receiving antenna 11 in this embodiment is a phased array antenna, the first phase shifter 60 performs phase adjustment on the received radio frequency signal, so that the phase of the radio frequency signal is restored to the phase of the radio frequency signal transmitted by the wireless charging device, which is convenient for subsequent rectification of the radio frequency signal.
Furthermore, the signal rectified by the rectifying circuit 20 is synthesized by the power synthesizing circuit 40 and then transmitted to the filter circuit 70, and the filter circuit 70 filters the received synthesized signal, thereby further filtering out harmonic signals possibly existing after rectification, and ensuring that the battery 30 is charged by direct current only through direct current signals.
It should be noted that the structure of the wireless charging receiving apparatus according to the embodiment of the present application may be adjusted according to the needs of practical applications, for example, when a phased array antenna is not used as the receiving antenna 11, the first phase shifter 60 may not be provided, that is, the rectifying circuit 20 is connected to the corresponding receiving antenna 11 through the matching circuit 50, for example, when the transmission speed meets the requirement, the matching circuit 50 may not be provided for cost saving, that is, the rectifying circuit 20 is connected to the corresponding receiving antenna 11 through the first phase shifter 60, and the connection relationship and the function of other components of the adjusted wireless charging receiving apparatus in the above example are not changed.
To sum up, the wireless charging receiving device of the embodiment of the application realizes the maximum power transmission of the receiving antenna through the matching circuit, and reduces the influence of the harmonic signal on the battery in the charging process through the filter circuit, thereby further improving the charging speed and efficiency of wireless charging and reducing the influence of the harmonic signal on the charging safety of the battery.
Based on the above embodiment, in order to solve the technical problems that the charging area of the wireless charging device is small, the limitation of the charging position of the device to be charged is high, and the like, the present application further provides a wireless charging transmitting device, and fig. 3 is a schematic structural diagram of the wireless charging transmitting device provided by the embodiment of the present application.
As shown in fig. 3, the wireless charging transmitting apparatus includes: a radio frequency power source 100, a plurality of second phase shifters 200, and a transmit antenna array 300.
The transmitting antenna array 300 includes a plurality of transmitting antennas 310, and the transmitting antenna array 300 may be configured according to the configuration of the receiving antenna array 10 in the above example, which is not described herein again. The connection relationship of the components is shown in fig. 3, wherein the rf power source 100 is connected to a first end of each second phase shifter 200, and a second end of each second phase shifter 200 is connected to the corresponding transmitting antenna 310.
In specific application, the rf power source 100 is configured to output an rf signal, wherein as a possible implementation, the rf power source 100 may output multiple paths of millimeter waves.
Further, the rf signal output by the rf power source 100 is transmitted to each second phase shifter 200, and the second phase shifters 200 perform phase shifting on the received rf signal, that is, adjust the phase of the rf signal to obtain the deflection of the rf signal, so as to change the direction of the rf signal. It can be understood that after the deflection of the rf signal, the rf power source direction is no longer limited, thereby enlarging the area of the charging region. Furthermore, the phase of the radio frequency signal can be adjusted to deflect the radio frequency signal to a set direction, so that the subsequent directional tracking transmission of the wireless charging receiving device at different positions is facilitated, namely, after the position of the target wireless charging receiving device is changed, the phase of the radio frequency signal can be adjusted to enable the radio frequency signal to point to a new target position.
Further, the second phase shifter 200 transmits the phase-shifted rf signal to the corresponding transmitting antenna 310, and each transmitting antenna 310 transmits the phase-shifted rf signal to the wireless charging receiving device. It can be understood that, since each of the transmitting antennas 310 transmits a radio frequency signal, the wireless charging transmitting apparatus realizes transmission of a multi-beam radio frequency signal, and further, the wireless charging transmitting apparatus in the embodiment of the present application can simultaneously charge a plurality of wireless charging receiving apparatuses. Moreover, since the transmitting antenna array 300 of the embodiment of the present application has higher transmitting power, more radio frequency signals can be transmitted in a unit time, which is beneficial for the wireless charging receiving device to receive more radio frequency signals, thereby further improving the wireless charging speed and the signal conversion rate.
It should be noted that, in an embodiment of the present invention, as shown in fig. 4, on the basis of fig. 3, the wireless charging transmitting apparatus according to the embodiment of the present application may further include a plurality of power amplifiers 400. Wherein the plurality of power amplifiers 400 are connected to the corresponding second phase shifters 200 at first ends thereof and to the corresponding transmitting antennas 310 at second ends thereof. In specific application, the power amplifier 400 is used for amplifying the phase-shifted rf signal to increase the strength of the rf signal, thereby facilitating subsequent reception of the rf signal.
Therefore, the wireless charging transmitting device of the embodiment of the application adjusts the phase of the radio frequency signal through the phase shifter, so that the radio frequency signal can deflect to the set direction, the area of a charging area is enlarged, and the wireless charging receiving device at different positions is favorably subjected to directional tracking charging. And the multi-path radio frequency signals are transmitted through the transmitting antenna array, so that a plurality of devices to be charged are charged at the same time, and the wireless charging efficiency is improved.
