[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] according to Figure 1As shown, a microwave wireless charging device 900 includes at least a wireless transmitting module 10 and a wireless receiving module 20. Specifically, the wireless transmitting module 10 includes a timer 100, a power supply 110, a processor 120, a microwave signal generator 130, a curved resonant relay module 140, a first wireless module 150, and a transmitting antenna module 160. The timer 100 operates within the processor 120 of the wireless transmitting module 10 and can send a timing signal at a predetermined time. Upon receiving the timing signal, the processor 120 can charge the device to be charged 1000. The microwave signal generator 130 generates a microwave signal after the processor 120 sends a signal.

[0020] Furthermore, the present invention uses a curved resonant relay module 140 disposed inside the shell for the microwave signal generated by the microwave signal generator 130. The curved resonant relay wireless charging utilizes the principle of magnetic field resonance. When the resonant circuit at the power transmitting end oscillates at a certain frequency, the resonant circuit at the power receiving end will also generate oscillations of the same frequency, thereby generating an induced electromotive force, which is then charged after rectification and filtering, and its curved shape is designed to achieve a specific electromagnetic effect. In this way, there is no need for a fixed position, the charging distance will be longer than the traditional charging distance, and the anti-interference ability will be improved. This method has been slightly improved compared to the original traditional wireless charging, but resonant charging still has some problems such as insufficient transmission distance and relatively low charging efficiency.

[0021] Furthermore, the RF antenna and transmitting antenna module 160 are disposed inside the housing and connected to the curved resonant relay module 140. Specifically, the RF antenna is responsible for transmitting RF radio frequency energy, generating a high-frequency radio frequency signal to excite an electromagnetic field, and transmitting the electromagnetic field to the receiving end. The receiving module converts the electromagnetic field into electrical energy through resonance technology and charges the device to be charged 1000.

[0022] Furthermore, the wireless receiving module 20 comprises at least a microwave receiver 200, a power collection circuit 210, a second wireless module 220, and the microwave receiver 200 for receiving radio frequency energy emitted by the RF antenna and then converting the RF radio frequency energy into electrical energy to charge the device to be charged 1000. Specifically, a wireless communication connection is established between the microwave receiver 200 and the transmitting antenna module 160, and the second wireless module 220 is used to receive the power supply of the device to be charged 1000 collected by the power collection circuit 210, which is then transmitted by the second wireless module to the first wireless module 150 of the wireless transmitting module 10, and the second wireless module establishes a wireless communication connection with the first wireless module.

[0023] Furthermore, the RF antenna module and the curved resonant relay 140 are both located within the housing of the microwave wireless device. The RF antenna module 160 includes an RF antenna 600, an antenna adjustment bracket 610, a first unit vibrator 620, a second unit vibrator 640, and a coaxial cable 630. The RF antenna 600 is used to transmit RF radio frequency energy for reception by the microwave receiver 200. The antenna adjustment bracket 610 is used to adjust the position and radiation direction of the RF antenna 600, increasing the direction of the radiated energy to enhance the freedom and flexibility of charging of the wireless charging device. The first unit vibrator 620 and the second unit vibrator 640 are located facing each other. The first unit vibrator 620 and the second unit vibrator 640 interact with each other to guide and amplify electromagnetic waves, thereby enhancing the electromagnetic signal of the antenna. Specifically, the first unit vibrator 620 and the second unit vibrator 640 are of similar size and length and are both connected to the antenna adjustment bracket 610. The first and second unit vibrators are connected via a coaxial cable 630. One end of the antenna adjustment bracket is connected to the RF antenna, and the other end is connected between the first unit oscillator 620 and the second unit oscillator 640.

[0024] Furthermore, the coaxial line 630 can transmit radio frequency signals, ensure that the signals are transmitted from the antenna and help reduce losses during the transmission process, thereby improving signal stability and enabling the receiving device to receive clearer and more stable signals.

[0025] Furthermore, the microwave receiver 200 includes a receiver similar to the receiving RF antenna module and at least includes the substance in the RF antenna module 160, so as to be able to efficiently receive the energy emitted by the RF radio frequency.

[0026] Furthermore, the curved resonant relay 140 includes at least contacts 500, a main body box 510, and other components. Contacts 500 are used to conduct the circuit. When an audio current with the same resonant frequency as the reed passes through the relay coil, the armature generates mechanical resonance under the influence of the audio alternating magnetic field, causing the movable contact on the reed to contact and conduct. The main body box 510 includes a coil, a spring, and other components. Specifically, the shape of the main body box 510 and the physical shapes of the coils and other components within it are not limited.

[0027] Example 2

[0028] In another embodiment, different from Example 1, the reference Figure 2The device includes at least a wireless reflection module 10, a wireless receiving module 20, and a remote control module 30. In addition to the above, the wireless transmitting module 10 also includes an MCU signal processing module 170 for decoding and processing control signals received from the first wireless module 220. The wireless receiving module is basically the same as described above. The second wireless module 220 establishes a wireless communication connection with the first wireless module 150, and the microwave receiver 200 establishes a wireless communication connection with the transmitting antenna module 160. The power collection circuit 210 collects the power of the power supply of the device to be charged 1000 and sends it to the first wireless module through the second wireless module 220, facilitating intelligent and convenient charging. The remote control module 30 includes at least a control signal generation module 400 and a microwave transmitter 300.

[0029] Furthermore, the control signal generation module 400 is used to generate signals such as the charging time point or charging status that need to be controlled. Specifically, after the control signal generation module 400 generates the signal, it will perform operations such as encrypting the signal. The microwave transmitter 300 is used to transmit the control signal generated by the control signal generation module 400 to the first wireless module 150 of the wireless transmission module 10 via wireless communication, and then from the first wireless module to the MCU signal processing module 170. Specifically, the MCU signal processing module 170 decompresses and receives the control signal, and then generates a signal and sends it to the processor 120, forming a more intelligent solution.

[0030] Furthermore, the first wireless module 150 will screen Figure 2 In the example, if the control signal of the microwave transmitter 300 of the remote control module 30 is first transmitted to the MCU signal processing module 170, the signal is processed by the MCU signal processing module 170 and then transmitted to the processor 120. If the second wireless module 220 of the wireless receiving module 20 sends a signal to the first wireless module 150, the first wireless module 150 transmits the signal directly to the processor 120.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
