[0058] In order to solve the problems in the background technology, the embodiments of the present application provide a wireless charging control method, device and wireless charging system.

[0059] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application can be combined with each other if there is no conflict.

[0060] like Figure 1 As shown, it is a structural schematic diagram of the wireless charging system provided in an embodiment of the present application. The wireless charging system may include at least two transmitting terminals 101. In addition to the at least two transmitting terminals 101, the wireless charging system may also include at least two devices to be charged 102. Each transmitting terminal 101 includes at least two transmitting units. Each device to be charged 102 includes at least two receiving units. Each transmitting unit of each transmitting terminal 101 contains a charging signal sent by the transmitting terminal 101. Each transmitting unit is used to wirelessly charge at least one device to be charged 102. For example: each transmitting terminal 101 may include t*n transmitting units, each transmitting unit has a unique identifier, and each transmitting unit may be arranged in a matrix array, each row includes t transmitting units, and there are n rows in total. Each device to be charged 102 includes r*s receiving units, each receiving unit has a unique identifier, and each receiving unit may be arranged in a matrix array, each row includes r receiving units, and there are s rows in total. The number of transmitting units included in different transmitting ends 101 can be the same or different, and the number of receiving units included in different devices to be charged 102 can be the same or different. The embodiment of the present application does not limit this. The transmitting end 101 can be a base station or a wireless charging device. The embodiment of the present application only takes the base station as an example for illustration. The device to be charged 102 can be but is not limited to the following devices: smart mobile terminals (such as smart phones), smart home devices, smart cars, etc. The embodiment of the present application takes the smart mobile terminal as an example for illustration.

[0061] like Figure 2As shown, it is a schematic diagram of an implementation flow of a wireless charging control method implemented on the side of the device to be charged provided by an embodiment of the present application. The wireless charging control method is applied to the above-mentioned wireless charging system. The wireless charging control method may specifically include the following steps:

[0062] S21. The device to be charged detects the wireless signal transmitted by the transmitting end of the wireless charging system through at least two established wireless charging paths.

[0063] In a specific implementation, the wireless charging transmitter (such as a base station) can pre-send the charging signal to each transmitting unit it contains, and transmit the corresponding charging signal to each receiving unit through each transmitting unit. For example, the transmitter can pre-send the charging signal of the same intensity to each transmitting unit it contains. The power of the charging signal on each transmitting unit is the same. The charging signal is the electromagnetic wave sent by the base station. The charging signal on each transmitting unit can be transmitted through the antenna. The charging signals on different transmitting units can be distinguished by any information such as frequency (i.e., the frequency of the electromagnetic wave transmission center), encoding method (such as PN code, Walsh code, etc.), transmission time sequence information, or transmission azimuth (angle) information. The transmission time sequence is the time sequence in which the base station sends the charging signal to each transmitting unit. Taking the transmission azimuth as an example, since each transmitting unit transmits the charging signal through the antenna at a different azimuth angle, any receiving unit in a device to be charged will receive different intensities of the charging signals sent by each transmitting unit.

[0064] Specifically, any device to be charged detects wireless charging signals transmitted by the base station through at least two established wireless charging paths, wherein the at least two wireless charging paths are wireless transmission channels between each transmitting unit of the base station (i.e., the transmitting end) and each receiving unit of the device to be charged. That is, any device to be charged detects the charging signal transmitted by the transmitting unit of the base station received by each receiving unit contained therein. In a specific implementation, a device to be charged can receive charging signals transmitted by transmitting units from different transmitting ends. A wireless charging path can be formed between any receiving unit and any transmitting unit. For a base station with t*n transmitting units and a device to be charged with r*s receiving units, there are a total of (t*n)*(r*s) wireless charging paths. The identifier of each wireless charging path can be represented by the identifier of the transmitting unit and the identifier of the receiving unit constituting the wireless charging path. For example, the identifier of a wireless charging path can be represented as (x, y), where x is the identifier of the transmitting unit constituting the wireless charging path, and y is the identifier of the receiving unit constituting the wireless charging path.

[0065] S22: Determine the quality of the received signal and select a wireless charging path that meets a preset received signal quality condition.

[0066] In specific implementation, there are two ways to select a wireless charging path that meets the preset received signal quality conditions:

[0067] Method 1: The device to be charged can select one or more wireless charging paths with the highest received charging signal strength as the target wireless charging path.

[0068] Method 2: The device to be charged can sort the received charging signal strengths in descending order, select the wireless charging paths corresponding to the first N charging signals, and then select one or more wireless charging paths from these N wireless charging paths with the highest charging signal strengths.

[0069] If the device to be charged selects multiple wireless charging paths, the multiple transmitting units of the transmitting end will simultaneously send charging signals to the multiple receiving units of the device to be charged to charge the device to be charged. In this way, the wireless charging efficiency can be effectively improved and the wireless charging time can be shortened.

[0070] S23: Control charging via the selected wireless charging path.

[0071] As a possible implementation, after selecting a wireless charging path, the device to be charged may also report identification information of the selected wireless charging path to a corresponding transmitter to initiate a wireless charging request to the transmitter.

[0072] In a specific implementation, the device to be charged reports the identification information of the selected wireless charging path to the corresponding first transmitter. After receiving the identification information of the wireless charging path reported by the device to be charged, the first transmitter sends a charging instruction to the device to be charged. After receiving the charging instruction from the first transmitter, the device to be charged performs charging according to the selected wireless charging path. The first transmitter is the transmitter to which the transmitting unit corresponding to the selected wireless charging path belongs. In a specific implementation, the device to be charged may carry the identification information of the wireless charging path in the wireless charging request and send it to the first transmitter. This embodiment of the present application does not limit this.

[0073] It should be noted that if the charging signal strength sent by the transmitting unit of the first transmitting end remains unchanged when charging other devices to be charged and when not charging other devices to be charged, the device to be charged may not send a wireless charging request to the first transmitting end, but directly charge according to the selected wireless charging path. This embodiment of the present application is not limited to this.

[0074] Specifically, the device to be charged can be charged as follows: Figure 3 The process shown here controls charging via the selected wireless charging path and includes the following steps:

[0075] S231 : Utilize a receiving unit corresponding to the selected wireless charging path to receive a first charging signal sent by a transmitting unit corresponding to the wireless charging path.

[0076] In a specific implementation, the device to be charged utilizes the receiving unit corresponding to the selected target wireless charging path to receive the charging signal sent by the transmitting unit corresponding to the wireless charging path, which can be recorded as the first charging signal.

[0077] S232: Utilize the electric energy storage unit to convert the first charging signal into an electric signal.

[0078] In specific implementation, an energy storage unit is provided on the device to be charged. The device to be charged uses the energy storage unit to store the first charging signal sent by the transmitting unit and converts the first charging signal (i.e., electromagnetic wave) into an electrical signal. In this way, wireless charging of the device to be charged can be achieved through the selected wireless charging path.

[0079] In a specific implementation, the electric energy storage unit may include, but is not limited to, a magnetoelectric sensor. The device to be charged uses the magnetoelectric sensor to convert the first charging signal into an electric signal. This embodiment of the present application does not limit this.

[0080] Here is an example to illustrate: Figure 4 In the wireless charging example diagram shown, the base station serves as the transmitter of the wireless charging system, i.e., the power supply, and mobile terminals 1 and 2 serve as the receivers of the wireless charging system: the devices to be charged are the power receivers. The base station has 8 transmitter units: t1 to t8, and mobile terminals 1 and 2 each have 4 receiver units: r1 to r4. The transmitter units of the base station can be distinguished by their transmission directions. Figure 4As can be seen from the figure, the transmission directions of transmitting units t1 to t8 point to 8 different directions respectively. There are 8*4=32 wireless charging paths between mobile terminal 1 and the base station, and there are also 32 wireless charging paths between mobile terminal 2 and the base station. Mobile terminal 1 and mobile terminal 2 respectively select the wireless charging path with the highest received charging signal strength from the wireless charging paths between themselves and the base station. Among them, the optimal charging path selected by mobile terminal 1 is: (t4, r3), then mobile terminal 1 uses the wireless charging path composed of transmitting unit t4 and receiving unit r3 for wireless charging, that is, transmitting unit t4 sends the charging signal to receiving unit r3 of mobile terminal 1 to charge mobile terminal 1; the optimal charging path selected by mobile terminal 2 is: (t6, r2), then mobile terminal 2 uses the wireless charging path composed of transmitting unit t6 and receiving unit r2 for wireless charging, that is, transmitting unit t6 sends the charging signal to receiving unit r2 of mobile terminal 2 to charge mobile terminal 2. Assuming that mobile terminals 1 and 2 are very close to each other, and that the transmitting unit in the optimal charging path selected by mobile terminals 1 and 2 is the same, for example, if mobile terminal 1 selects the optimal path (t5, r3) and mobile terminal 2 selects the optimal path (t5, r2), and both use the same transmitting unit, t5, then the base station's transmitting unit t5 can simultaneously send charging signals to receiving unit r3 of mobile terminal 1 and receiving unit r2 of mobile terminal 2, thereby wirelessly charging both mobile terminals 1 and 2 simultaneously through transmitting unit t5. Mobile terminals 1 and 2 can then complete adaptive long-distance wireless charging without human intervention.

[0081] In the wireless charging control method provided in the embodiment of the present application, the wireless charging system includes at least two transmitting ends and at least two devices to be charged, each transmitting end includes at least two transmitting units, each device to be charged includes at least two receiving units, each transmitting unit of each transmitting end contains a charging signal sent by the transmitting end, each device to be charged detects the wireless signal transmitted by the transmitting end of the wireless charging system through at least two wireless charging paths, determines the quality of the received signal, selects a wireless charging path that meets the preset received signal quality conditions, and performs charging control through the selected wireless charging path. In this way, the device to be charged can adaptively move between at least two wireless charging paths between the transmitting end and the wireless charging system. In the charging path, a wireless charging path that meets the receiving signal quality conditions is selected for charging, which effectively reduces the charging energy loss of the transmitter and realizes efficient long-distance wireless charging. Since the transmitter includes at least multiple transmitting units, each transmitter can establish multiple wireless charging paths with multiple receiving units of multiple devices to be charged for selection by multiple devices to be charged, realizing one-to-many centralized wireless charging, further improving the wireless charging efficiency, and further reducing the charging energy loss of the wireless charging transmitter. In the embodiment of the present application, the energy transmitted by the base station is used to wirelessly charge the device to be charged, so that the base station energy is better utilized and the energy benefit ratio is improved.
