Summary of the Invention

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of the present application provide a wireless charging method, which is applied to a wireless charging device. The wireless charging device includes: a housing and N antennas. The housing includes a cavity for placing a device to be charged. The N antennas are respectively arranged on different inner walls of the cavity, where N is an integer greater than 1. The method includes:

[0009] a determination module, configured to determine M target antennas from the N antennas, wherein the target antennas are antennas that successfully match the device to be charged and have a charging efficiency for the device to be charged greater than a preset threshold, where M is a positive integer less than or equal to N;

[0010] A control module is used to control the M target antennas to charge the device to be charged.

[0011] In a third aspect, an embodiment of the present application provides an electronic device comprising a processor, a memory, and a program or instruction stored in the memory and executable on the processor, wherein the program or instruction, when executed by the processor, implements the steps of the method described in the first aspect.

[0012] In a fourth aspect, an embodiment of the present application provides a readable storage medium, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the method described in the first aspect are implemented.

The higher the charging power, the higher the charging efficiency. Thus, by selecting an antenna whose charging efficiency for the device to be charged is greater than a preset threshold, the charging efficiency of the device to be charged can be increased.

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0030] See also Figure 1 , Figure 1 This is a flow chart of a wireless charging method provided in an embodiment of the present application, which is applied to a wireless charging device, such as Figure 2 and Figure 3As shown, the wireless charging device includes: a housing 10 and N antennas 30, the housing 10 includes a receiving cavity for placing the device to be charged 20, and the N antennas 30 are respectively arranged on different inner walls of the receiving cavity, where N is an integer greater than 1; Figure 1 As shown, the above method includes the following steps:

[0031] Step 101: Determine M target antennas from the N antennas, where the target antennas are antennas that successfully match the device to be charged and have a charging efficiency for the device to be charged greater than a preset threshold, and M is a positive integer less than or equal to N.

[0032] It should be noted that when the value of M is 1, the target antenna can be the antenna that successfully matches the device to be charged and has the highest charging efficiency for the device to be charged. In this way, the highest charging efficiency for the device to be charged can be ensured.

[0033] The type of antenna is not limited here. As an optional implementation, all antennas can be millimeter wave antennas. The millimeter waves emitted by millimeter wave antennas have the characteristics of wide bandwidth, low propagation attenuation, and little influence from natural light and thermal radiation sources. Therefore, the energy loss during transmission is relatively small. This reduces the energy loss of millimeter waves, thereby further improving the charging efficiency of the charging device.

[0034] Among them, N antennas are respectively arranged on different inner walls of the accommodating cavity. The specific arrangement method is not limited here. The number of antennas arranged on different inner walls of the accommodating cavity can be the same, for example: Figure 2 , an antenna 30 may be provided on each inner wall of the accommodating cavity, or, see Figure 3 , two antennas 30 can be set on each inner wall of the accommodating cavity. Of course, the number of antennas set on different inner walls of the accommodating cavity can also be different.

[0035] It should be noted that the specific shape of the housing 10 is not limited here, and the housing 10 can be in the shape of a cube or a triangular pyramid.

[0036] As an optional embodiment, at least one antenna is provided on each inner wall of the accommodating cavity. Thus, since at least one antenna can be provided on each inner wall of the accommodating cavity, the greater the number of antennas, the more antennas can be controlled to wirelessly charge the device to be charged, thereby further improving the charging efficiency of the device to be charged.

[0037] It should be noted that since the target antenna is an antenna that successfully matches the device to be charged and has a charging efficiency for the device to be charged greater than a preset threshold, when the target antenna is used to charge the device to be charged, the charging efficiency of each target antenna can be guaranteed to be high.

[0038] In addition, a fan may be provided on the inner wall of the accommodating cavity. By providing the fan, the heat generated by the antenna when wirelessly charging the device to be charged can be dissipated.

[0039] In addition, a door that can be switched between an open and closed state can be provided on an inner wall of the accommodating chamber. Through this door, the device to be charged can be placed in or removed from the accommodating chamber. Furthermore, when the door is open, the position of the device to be charged within the accommodating chamber can be adjusted. It should be noted that the door may or may not be provided with an antenna. This is not specifically limited here.

[0040] It should be noted that each step in the embodiment of the present application can be executed by the controller of the wireless charging device 100, see Figure 4 , and the above-mentioned controller can be referred to as a control unit 16.

[0041] As an optional implementation, see Figure 4 The wireless charging device 100 further includes a rectifier and filter circuit 12, a high-frequency conversion circuit 13, and a power amplifier circuit 14. The rectifier and filter circuit 12 is electrically connected to a power source and is electrically connected to the antenna via the high-frequency conversion circuit 13 and the power amplifier circuit 14. Thus, the rectifier and filter circuit 12, the high-frequency conversion circuit 13, and the power amplifier circuit 14 facilitate current conversion within the wireless charging device 100. Furthermore, after the current passes through the power amplifier circuit 14, the current transmission performance is enhanced, thereby improving the charging efficiency of the device 200 to be charged and reducing the charging time of the device 200 to be charged.

[0042] It should be noted that the power supply may also be referred to as an AC power supply 11 , and the antenna may also be referred to as a transmitting antenna 15 .

[0043] In addition, the wireless charging device 100 may further include a display unit 17 , and the controller may be electrically connected to the rectifying and filtering circuit 12 , the high-frequency conversion circuit 13 , the power amplifying circuit 14 , the antenna, and the display unit 17 , respectively.

[0044] Among them, the power supply connected to the rectifier and filter circuit 12 can be an AC power supply, and the rectifier and filter circuit 12 can convert AC power into DC power, so that the various components in the wireless charging device 100 can more conveniently identify DC power, and the controller can output a driving signal to the high-frequency conversion circuit 13. In this way, under the action of the driving signal and the DC power output by the rectifier and filter circuit 12, the high-frequency conversion circuit 13 generates a high-frequency signal, and the high-frequency signal is further amplified by the power amplifier circuit 14 and the energy is transmitted through the antenna.

[0045] In addition, the controller can also control the display unit 17 to display various information, including whether the device to be charged 200 is successfully paired with the target antenna, the charging status of the device to be charged 200 (including whether it is in the charging state, the current charging amount, etc.) and at least one of the abnormal information of the device to be charged 200 or the wireless charging device 100.

[0046] The device to be charged 200 may include a receiving antenna 201, a rectifier and converter circuit 202, and a load 203. The receiving antenna 201 may receive energy transmitted by the antenna, and convert the energy into electrical energy through the rectifier and converter circuit 202, which then flows to the load 203. The load 203 may be referred to as a battery, thereby achieving the effect of wirelessly charging the battery of the device to be charged 200.

[0047] As an optional embodiment, the housing is further provided with a position detection element, and the determining of M target antennas from the N antennas includes:

[0048] Acquiring the position of the device to be charged by the position detection component;

[0049] M target antennas are determined from the N antennas according to the position of the device to be charged.

[0050] The position detection element may also be referred to as a position sensor, and the specific type is not limited here. For example, it may be an infrared sensor or an ultrasonic sensor.

[0051] In this embodiment, in addition to successfully matching the device to be charged and ensuring that the charging efficiency of the device is greater than a preset threshold, the target antenna is determined based on the location of the device to be charged. This allows antennas that are closer to the device to be charged to be identified as target antennas, making the determination of the target antenna more accurate. This also allows the target antenna to better meet the charging requirements of the device to be charged (i.e., antennas that are closer to the device to be charged are generally more likely to meet charging requirements).

[0052] As an optional implementation manner, determining M target antennas from the N antennas according to the position of the device to be charged includes:

[0053] Adjust at least one of the position and orientation of at least some of the N antennas according to the position of the device to be charged;

[0054] M target antennas are determined from the adjusted antennas.

[0055] In this embodiment, at least one of the position and orientation of at least some of the antennas can be adjusted according to the position of the device to be charged in the accommodating cavity, and the target antenna can be determined from the adjusted antennas. In this way, by adjusting at least one of the position and orientation of the antennas, as many antennas as possible can meet the conditions of the target antenna, so that the charging efficiency of the device to be charged can be further improved.

[0056] For example: See Figure 6 and Figure 7 , N antennas include a first antenna 301, a second antenna 302 and a third antenna 303, Figure 6 and Figure 7 The arrows on each antenna in the figure represent the movement and rotation directions of the first antenna 301, the second antenna 302 and the third antenna 303, respectively. Figure 6 A in the figure represents the position of the first antenna 301 after it moves. Figure 7 B in the middle represents the position of the first antenna 301 after rotation.

[0057] Also, see Figure 5 , Figure 5 The position of the antenna 30 on the left side of the center has not been moved, and the direction has not been adjusted. Figure 5 The direction of the antenna 30 on the middle right side is adjusted to be set toward the smart watch 22.

[0058] It should be noted that the closer the antenna is to the device to be charged, the higher the charging efficiency of the device to be charged. When the radiation direction of the antenna is toward the receiving antenna of the device to be charged, the charging efficiency of the device to be charged is also higher.

[0059] In addition, the antenna can be adhered to the inner wall of the accommodating cavity; or, a accommodating groove can be opened on the inner wall of the accommodating cavity, and the antenna can be embedded in the above-mentioned accommodating groove; or, the antenna can be movably connected to the inner wall of the accommodating cavity, so that the antenna can at least move and rotate relative to the inner wall of the accommodating cavity, thereby adjusting at least one of the position and orientation of the antenna.

[0060] For example, a slot can be formed on the inner wall of the accommodating cavity, and the antenna can be connected to the slot via a connector. The connector can be movable relative to the slot, so that the position of the antenna relative to the inner wall of the accommodating cavity can be adjusted as the connector moves within the slot. Furthermore, the antenna can be rotatably connected to the connector, meaning that the antenna can rotate relative to the connector, or the connector can rotate relative to the slot. Thus, the antenna's orientation can be adjusted by rotating either the antenna or the connector.

[0061] It should be noted that when it is determined that the target antenna does not exist among the above-mentioned N antennas, as an optional implementation, the method also includes: when the target antenna does not exist, outputting a prompt message, and the prompt message is used to prompt to adjust at least one of the position and orientation of the device to be charged.

[0062] In this embodiment, a prompt message can be output to prompt the user to adjust at least one of the position and orientation of the device to be charged in the accommodating cavity, so that the device to be charged after adjustment can have a target antenna, thereby controlling the target antenna to charge the device to be charged, thereby improving the charging efficiency of the device to be charged.

[0063] As another optional implementation, when the target antenna does not exist, at least one of the position and orientation of the device to be charged may be controlled and adjusted so that the target antenna exists on the device to be charged.

[0064] In this embodiment, when there is no target antenna, the wireless charging device can automatically adjust at least one of the position and orientation of the device to be charged. In this way, there is no need for the user to adjust at least one of the position and orientation of the device to be charged, which improves the intelligence of the adjustment method for the device to be charged and, at the same time, can also improve the accuracy of the adjustment effect of the device to be charged.

[0065] It should be noted that in order to facilitate the automated adjustment of the device to be charged, a tray with adjustable position and orientation can be set in the accommodating cavity, and the device to be charged can be set on the tray. In this way, the position or orientation of the device to be charged can be adjusted accordingly by adjusting the position or orientation of the tray.

[0066] Step 102: Control the M target antennas to charge the device to be charged.

[0067] Among them, the target antenna can radiate energy, and the device to be charged can be provided with a receiving antenna for receiving the above energy, and then converting the received energy into electrical energy, and inputting the electrical energy into the battery, thereby completing the charging of the battery.

[0068] The number of devices to be charged is not limited here. For example, the number of devices to be charged can be one or at least two. Figure 2 and Figure 3 For example, the number of devices to be charged can be two, that is, the device to be charged 20 can include a mobile phone 21 and a smart watch 22. When wirelessly charging the mobile phone 21 and the smart watch 22, the above steps can be performed respectively to complete the wireless charging of the mobile phone 21 and the smart watch 22.

[0069] In the embodiment of the present application, through steps 101 to 102, M target antennas can be determined from N antennas, and the M target antennas can be controlled to charge the device to be charged. The target antennas are antennas that are successfully matched with the device to be charged and whose charging efficiency for the device to be charged is greater than a preset threshold. In this way, the charging efficiency of the device to be charged can be improved.

[0070] When a wireless charging device is wirelessly charging an electronic device, the greater the charging distance between the wireless charging device and the electronic device, the lower the charging efficiency. However, the shorter the charging distance, the higher the charging efficiency. Accordingly, the lower the charging power used by the wireless charging device, the lower the charging efficiency. The higher the charging power, the higher the charging efficiency. Thus, by selecting an antenna whose charging efficiency for the device to be charged is greater than a preset threshold, the charging efficiency of the device to be charged can be increased.

[0071] The following two embodiments are used as examples to illustrate the specific Figure 8 and Figure 9 Steps shown.

[0072] Figure 8 and Figure 9 The mobile terminal in the embodiment can be understood as the device to be charged in the above embodiment, and the wireless charging device can be understood as the wireless charging device in the above embodiment. The control unit can refer to the controller in the above embodiment. Figure 9 The position detection unit may refer to the position detection element in the above embodiment, and the antenna angle may refer to the direction of the antenna.

[0073] The wireless charging device in the embodiments of the present application can be a device, or a component, integrated circuit, or chip in a terminal. The device can be a mobile electronic device or a non-mobile electronic device. For example, the mobile electronic device can be a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. The non-mobile electronic device can be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), an ATM, or an kiosks, etc., which are not specifically limited in the embodiments of the present application.
