[0032] The present application provides a wireless charging energy transmission device, a wireless charging method, a system, a terminal and a medium. Through a wireless charging energy transmission end, each wireless charging transmission coil is enabled in sequence according to a set time interval to charge a wireless charging energy receiving end to which one or more wireless charging transmission coils are respectively connected. The wireless charging energy transmission end in the present application is in a dormant state when not connected to a wireless charging energy receiving end, and starts working and charging the wireless charging energy receiving end when connected to the wireless charging energy receiving end, so it has lower standby power consumption.

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the technical solution in the embodiments of the present invention is further described in detail through the following embodiments and in combination with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the invention.

[0034] like Figure 1 As shown, it is a schematic diagram of the structure of the wireless charging energy sending device 1 in an embodiment of the present invention.

[0035] The wireless charging energy sending device 1 comprises:

[0036] A plurality of wireless charging and transmitting coils 11 and a wireless charging energy transmitting end 12 connected to each wireless charging and transmitting coil 11;

[0037] The wireless energy charging transmitting end 12 is used to enable each wireless energy charging transmitting coil 11 in turn at a set time interval to charge the wireless energy charging receiving end 2 to which one or more wireless energy charging transmitting coils 11 are respectively connected.

[0038] In one embodiment, if Figure 2 As shown, each wireless charging and transmitting coil 11 is respectively connected to an oscillating circuit for generating an oscillating signal.

[0039] In one embodiment, the oscillation circuit is an LC oscillation circuit.

[0040] In one embodiment, a method for charging a wireless charging energy receiving end to which one or more wireless charging transmitting coils are respectively connected includes: enabling each wireless charging transmitting coil in turn according to a set time interval; determining a wireless charging transmitting coil connected to a wireless charging energy receiving end, and charging the corresponding wireless charging energy receiving end through each determined wireless charging transmitting coil.

[0041] The following will describe in detail the wireless charging method of the wireless charging energy sending device in conjunction with the accompanying drawings:

[0042] like Figure 1 As shown, the wireless energy charging transmitting end 12 charges the wireless energy charging receiving end 2 connected to one or more wireless energy charging transmitting coils 11 respectively through each wireless energy charging transmitting coil 11. When the wireless energy charging transmitting end 12 does not charge the wireless energy charging receiving end 2, the wireless energy charging transmitting end 12 is in a low power consumption state. The wireless energy charging transmitting end 12 enables each wireless energy charging transmitting coil 11 in turn at a set time interval, detects whether each wireless energy charging transmitting coil 11 is connected to the wireless energy charging receiving end 2, and after determining that the wireless energy charging receiving end 2 is connected, the wireless energy charging transmitting coil 11 connected to the wireless energy charging receiving end 2 transmits energy with each wireless energy charging receiving end 2, and charges each wireless energy charging receiving end 2. In this wireless charging mode, since it is in a dormant state when the wireless energy charging receiving end is not connected, and starts working and charging it when the wireless energy charging receiving end 12 is connected, the wireless energy charging transmitting end 12 has lower standby power consumption.

[0043] For example, if Figure 1As shown, the wireless energy charging transmission device 1 includes three transmitting coils, namely, transmitting coil A, transmitting coil B, and transmitting coil C. At time T1, time T2, and time T3, the wireless energy charging transmitting end 12 enables each coil in the order of transmitting coil A, transmitting coil B, and transmitting coil C. The time interval between time T2 and time T1 and the time interval between time T2 and time T3 are both set time intervals.

[0044] At time T1, the wireless energy charging transmitter 12 first enables the transmitting coil A, and detects that the transmitting coil A is connected to a wireless energy charging receiver A. Then, the wireless energy charging transmitter 12 starts to enter the working state and charges each wireless energy charging receiver 2.

[0045] At time T2, the wireless charging energy transmitter 12 Figure 2 As shown, first enable the transmitting coil A, and if it is detected that the transmitting coil A is not connected to the wireless charging receiving end, then continue to enable the transmitting coil B, and if it is detected that the transmitting coil B is connected to a wireless charging receiving end B, the wireless charging transmitting end 12 continues to maintain the working state and charges each wireless charging receiving end 2.

[0046] At time T3, the wireless energy charging transmitter 12 first enables the transmitting coil A and detects that the transmitting coil A is not connected to the wireless energy charging receiver A; then enables the transmitting coil B and detects that the transmitting coil B is not connected to the wireless energy charging receiver B; then enables the transmitting coil C and detects that the transmitting coil C is not connected to the wireless energy charging receiver C. The wireless energy charging transmitter 12 is not connected to any wireless energy charging receiver 2 at time T3, and the wireless energy charging transmitter 12 enters a low power consumption state. When the wireless energy charging transmitter 12 detects that the wireless energy charging receiver 2 is connected again, it enters a working state.

[0047] It should be noted that the set time interval is usually in the millisecond level, so the wireless energy charging transmitter 12 will quickly detect the wireless energy charging receiver 2 and charge it.

[0048] It should also be noted that the above examples are only for better explaining various wireless charging situations and are not intended to limit the present invention.

[0049] In one embodiment, a method for determining a wireless charging and transmitting coil connected to a wireless charging energy receiving end includes: enabling each wireless charging and transmitting coil in turn so that an oscillation circuit connected to each wireless charging and transmitting coil generates an oscillation signal corresponding to each wireless charging and transmitting coil; calculating the number of oscillation cycles corresponding to the oscillation signal of each wireless charging and transmitting coil, and determining whether the number of oscillation cycles is less than a set cycle threshold; if the number of oscillation cycles corresponding to the oscillation signal of the wireless charging and transmitting coil is less than the set cycle threshold, determining that the wireless charging and transmitting coil is connected to the wireless charging and transmitting coil; if the number of oscillation cycles corresponding to the oscillation signal of the wireless charging and transmitting coil is not less than the set cycle threshold, determining that the wireless charging and transmitting coil is not connected to the wireless charging and transmitting coil.

[0050] In one embodiment, the oscillation circuit connected to each wireless charging and transmitting coil generates an oscillation signal corresponding to each wireless charging and transmitting coil, which is a damped oscillation signal.

[0051] In one embodiment, the method for calculating the number of oscillation cycles corresponding to the oscillation signal of each wireless charging and transmitting coil includes: using a counter in the wireless charging energy transmitting end, calculating the number of oscillation pulses of the oscillation signal amplitude of each wireless charging and transmitting coil between the first threshold level and the second threshold level to obtain the corresponding number of oscillation cycles.

[0052] In a specific embodiment, the wireless charging energy sending device also includes: a pulse generator, a first-level amplifier, a limiter and a level detector; the oscillation circuit connected to each wireless charging and transmitting coil generates an attenuated oscillation signal corresponding to each wireless charging and transmitting coil under the excitation of the pulse generator, and the attenuated oscillation signal corresponding to each wireless charging and transmitting coil is sent to the limiter and the level detector through the first-level amplifier, so that the counter in the wireless charging energy sending end can calculate the number of oscillation pulses of the oscillation signal amplitude of each wireless charging and transmitting coil between the first threshold level and the second threshold level.

[0053] The following will take the wireless charging transmission coil A as an example to explain how to calculate the number of oscillation cycles and how to determine whether the wireless charging transmission coil is connected to a wireless charging energy receiving end:

[0054] The counter in the wireless charging energy transmitting end starts counting the number of oscillation pulses output by the limiter when the amplitude of the attenuated oscillation signal of the wireless charging transmitting coil A reaches the first threshold level, that is, when the oscillation circuit connected to the wireless charging transmitting coil A starts to generate the attenuated oscillation signal. When the attenuated oscillation signal of the wireless charging transmitting coil A drops to the second threshold level, the counter stops counting. The counting result of the counter is the number of oscillation cycles corresponding to the attenuated oscillation signal of the wireless charging transmitting coil A.

[0055] After calculating the oscillation cycle number corresponding to the attenuated oscillation signal of the wireless charging transmitting coil A, it is determined whether the oscillation cycle number is less than the set cycle threshold. If it is less than the set cycle threshold, the wireless charging transmitting coil A is connected to the wireless charging energy receiving end; if it is not less than the set cycle threshold, the wireless charging transmitting coil A is not connected to the wireless charging energy receiving end.

[0056] The principle of judging whether a wireless charging receiver is connected by the number of oscillation cycles is as follows: Figure 4 As shown in FIG. 1 , a waveform diagram corresponding to an oscillation signal of a wireless charging transmitting coil is shown when the wireless charging energy receiving end is not connected. Figure 5 As shown, it is a waveform diagram corresponding to the oscillation signal of a wireless charging transmitting coil when connected to a wireless charging energy receiving end. Figure 4 as well as Figure 5 It can be seen that when the oscillation signal amplitude is between the first threshold level and the second threshold level, the number of oscillation cycles of the oscillation signal of the wireless charging and transmitting coil that is not connected to the wireless charging energy receiving end is different from the number of oscillation cycles of the oscillation signal of the wireless charging and transmitting coil that is connected to the wireless charging energy receiving end. By setting a cycle threshold, it is possible to distinguish between a wireless charging and transmitting coil that is connected to a wireless charging energy receiving end and a wireless charging and transmitting coil that is not connected to the wireless charging energy receiving end. It should be noted that when the oscillation signal amplitude is less than the second threshold level, the wireless charging energy receiving end cannot detect the oscillation signal, so after the oscillation signal amplitude is less than the second threshold level, the counter stops counting.

[0057] In a specific embodiment, the first threshold level is a 100% level, and the second threshold level is a 4.3% level.

[0058] It should be noted that the set cycle threshold is determined by a large amount of experimental data, and the set cycle threshold can be used to distinguish the wireless charging transmission coil connected to the wireless charging energy receiving end and the wireless charging transmission coil not connected to the wireless charging energy receiving end.

[0059] In one embodiment, if Figure 3 As shown, the wireless charging energy transmitting end 12 includes: an input power supply 121 and a transmitting end control chip 122 connected to the input power supply; wherein, the transmitting end control chip 122, under the power supply of the input power supply 121, enables each wireless charging transmitting coil 11 in turn according to a set time interval to determine the wireless charging transmitting coil 11 connected to the wireless charging energy receiving end and charges the corresponding wireless charging energy receiving end 2 through the wireless charging transmitting coil 11.

[0060] In one embodiment, if Figure 3As shown, a voltage and current acquisition module 123 is connected between the input power supply 121 and the transmitting end control chip 122; wherein, the voltage and current acquisition module 123 is used to collect the working status data of the wireless energy charging transmitting end 12 in real time to protect the wireless energy charging transmitting end 12; the working status data of the wireless energy charging transmitting end 12 includes: the working voltage data and the working current data of the wireless energy charging transmitting end 12.

[0061] In one embodiment, if the wireless energy charging transmission device outputs a fixed 20V, the power of the wireless energy charging receiving end that can be supported is between 5W and 60W.

[0062] In one embodiment, if Figure 3 As shown, each wireless energy charging receiving end 2 includes: a receiving coil 21 and a receiving device 22 connected to the receiving coil 21; wherein the receiving device 22 is communicatively connected to the wireless energy charging transmitting device 1 through the receiving coil 21.

[0063] In one embodiment, a receiving coil 21 is connected to a transmitting coil corresponding to the receiving coil 21 by means of a communication connection, so that the wireless charging energy transmitting end 12 charges the receiving device corresponding to the receiving coil 21 .

[0064] For example, if Figure 3 As shown, the receiving coil A is connected to a receiving device A, the receiving coil A is communicated with the transmitting coil A, and the wireless charging energy transmitting end 12 charges the receiving device A.

[0065] In one embodiment, the wireless energy charging transmission device 1 transmits data to each wireless energy charging receiving terminal 2 in an FSK transmission mode. The wireless energy charging receiving terminal 2 transmits data to the wireless energy charging transmission device 1 in an AM transmission mode.

[0066] It should be noted that FSK (Frequency Shift Keying) is a digital modulation technology that allows data transmission by changing the carrier frequency according to the digital modulation signal. FSK has the advantages of lower error probability, high SNR (Signal-Noise Ratio), higher noise immunity, etc. AM (Amplitude Modulation) is a technology that uses rapid control of the amplitude or power level of the carrier to receive audio signals transmitted at low frequencies.

[0067] In one embodiment, the receiving device 22 is a device that can be wirelessly charged, including: a smart phone, a smart watch, etc., which are not listed here.

[0068] In order to better illustrate the wireless charging energy sending device in the above embodiment, a specific embodiment is now provided.

[0069] Embodiment 1: A method for detecting software polling of a wireless charging device.

[0070] The detection wireless charging device software polls for wireless charging energy sending devices. Wireless charging energy sending devices, such as Figure 6 As shown, it includes: coil 1, coil 2... coil n. When the transmitting device is in standby mode, the oscillation signal is turned on at regular intervals to detect whether a receiving device is connected. At a certain moment, coil 1 is enabled to generate an oscillation signal of coil 1. If the number of oscillation cycles corresponding to the oscillation signal of coil 1 is less than the set threshold, it is determined that coil 1 is connected to a receiving device, and the wireless charging energy transmitting device enters the working state to charge the receiving device. If the number of oscillation cycles corresponding to the oscillation signal of coil 1 is not less than the set threshold, it is determined that coil 1 is not connected to a receiving device, and coil 2 continues to be detected whether it is connected to a receiving device. Each coil detects the receiving device according to the above method. If it is detected that coil 1, coil 2... coil n are not connected to a receiving device, the transmitting device continues to enter the standby state.

[0071] Similar to the above embodiment, the present invention provides a wireless charging method.

[0083] In one embodiment, each wireless energy charging receiving end includes: a receiving coil and a receiving device connected to the receiving coil; wherein the receiving device is communicatively connected to the wireless energy charging transmitting device via the receiving coil.

[0084] It should be noted that the implementation of the wireless charging method in this embodiment is similar to the implementation of the wireless charging energy sending device in the above embodiment, so it will not be repeated here.
