In another case, when in the power receiving mode, the electronic device may generate the relative positional relationship according to the strength and direction of the wireless charging energy emitted by the other electronic device.

The technical solution of the present application is described below with reference to FIG. 6 for the interaction process between the power supply device 21, the power receiving device 22, and the server 11. 6 is a schematic diagram of interaction of implementing a wireless charging solution according to an exemplary embodiment of the present application. As shown in FIG. 6, the mobile phone 13 as the power supply device 21, the mobile phone 15 as the power receiving device, and the server 11 are For example, the interaction process can include the following steps:

Step 602: The mobile phone 13 determines its own remaining power; when the remaining power is not less than the first preset power, it is set to the power supply mode and proceeds to step 604, and when the remaining power is not greater than the second preset power, is set to the power receiving mode. And end.

In this embodiment, it is assumed that the mobile phone 13 is equipped with a wireless charging transmitting end and a wireless charging receiving end at the same time. When the mobile phone 13 is in the power supply mode, the wireless charging transmitting end is configured to be in a usable state, that is, the mobile phone 13 can be applied to The other electronic device performs wireless charging; and when the mobile phone 13 is in the power receiving mode, the wireless charging transmitting end is configured to be in a restricted state, that is, the mobile phone 13 cannot wirelessly charge other electronic devices. For the wireless charging receiving end, the usage may be independent of the mode in which the mobile phone 13 is located, for example, the wireless charging receiving end may remain in a usable state; of course, when the wireless charging transmitting end is transmitting wireless charging energy outward, The wireless charging receiver is set to a limited state to avoid affecting the wireless charging efficiency of other electronic devices.

In step 604, the mobile phone 13 reports its geographical location to the server 11.

In this embodiment, the mobile phone 13 can periodically report the geographical location; or the mobile phone 13 can periodically detect the change of the geographical position of the mobile phone 13 and report the changed geographical position to the server 11 when the geographical location changes greatly; or When the geographical location of the mobile phone 13 is continuously changing rapidly, the mobile phone 13 may not be able to perform effective wireless charging on other electronic devices, and the mobile phone 13 may pause the reporting of the geographical location and wait for the geographical location to be unchanged or the change speed to be slow. Then resume reporting the location.

Step 606: The server 11 generates corresponding power supply device distribution data according to the received geographic locations uploaded by the respective power supply devices.

In this embodiment, the server 11 may separately obtain the information of the power supply device and the corresponding geographic location, thereby generating the power point device and the geographic location as the associated point of interest information, and further collecting the generated point of interest information into the power device distribution. data.

In step 608, the mobile phone 15 determines whether there is a charging demand for itself; when there is a charging demand, the process proceeds to step 610, otherwise it ends.

In this embodiment, the mobile phone 15 can determine that there is a charging requirement when the remaining power of the battery is not greater than the second preset power; wherein, when the mobile phone 15 is equipped with the wireless charging transmitting end and the wireless charging receiving end, the mobile phone 15 The battery can be actively switched to the power receiving mode if the remaining power of the battery is not greater than the second preset power, and it is determined that the charging demand exists.

Of course, the mobile phone 15 can also determine that there is a charging demand when receiving a power supply device inquiry command from the user, regardless of the remaining battery capacity.

In step 610, the handset 15 sends an inquiry request to the server 11, which includes the geographic location of the handset 15.

In step 612, the server 11 returns at least a portion of the power distribution device distribution data to the handset 15.

In the present embodiment, the server 11 can return all of the power supply device distribution data to the mobile phone 15. Alternatively, the server 11 may determine the power supply device in the corresponding wireless charging range according to the geographical location where the mobile phone 15 is located, and send the corresponding part of the power supply device distribution data to the mobile phone 15, thereby reducing the data of the power supply device distribution data returned by the server 11. The amount of responsiveness of the mobile phone 15 is increased.

The wireless charging range refers to a circular area in which the geographic location of the mobile phone 15 is centered and the preset distance is a radius; wherein the preset distance may be a preset default distance in the server 11, or may be a mobile phone 15 The user is set according to the actual situation, and this application does not limit this.

In step 614, the mobile phone 15 displays the nearby power supply device and determines the selected power supply device.

In this embodiment, the mobile phone 15 can display the power supply device in various ways. For example, the mobile phone 15 can show a map page as shown in FIG. 7, in which the location 70 where the mobile phone 15 is located can be marked, and within the range 71 with the location 70 as the center and the preset distance as the radius. The location of the point of interest corresponding to the power supply device in the vicinity of the mobile phone 15 can be shown. For example, FIG. 7 shows the power supply devices X1, X2, X3, X4, and the like. The user of the mobile phone 15 can adjust the range 71 to enlarge or reduce the display area for the location of the point of interest. At the same time, the user of the mobile phone 15 can also pan the map in the map page to browse other areas and the distribution of the charging device.

In one case, the handset 15 may only show the location of interest points within the range 71. In another case, the mobile phone 15 may show the location of the point of interest outside the range 71 while showing the location of the point of interest within the range 71, but the handset 15 may position the point of interest within the range 71. A detailed display is performed, and a probability display such as a point of interest location 72 other than the range 81 is performed.

When the user of the mobile phone 15 wishes to select a certain power supply device, the corresponding point of interest can be triggered by clicking or the like in the map page as shown in FIG. 7; for example, by triggering the location of the point of interest corresponding to the power supply device X1. The mobile phone 15 is wirelessly charged by selecting the power supply device X1.

Of course, in addition to the map page shown in FIG. 7, the mobile phone 15 can visually display the distribution data of the power supply device by other means. For example, as shown in FIG. 8, the mobile phone 15 can display a list page 80, and display nearby power supply devices from near to far within the list page 80; wherein the user can adjust the range of the point of interest location For example, the range in FIG. 8 is "within 500", and the user can expand or reduce the range by triggering the control 81 in the list page 80. Of course, the user can also switch between the map form and the list form in different scenarios. For example, when the user triggers the list option 73 shown in FIG. 7, the user can switch from the map form to the list form shown in FIG. 8. When the user triggers the map option 82 shown in FIG. 8, it can be switched from the list form to the map form shown in FIG.

Step 616, the mobile phone 15 sends a selection message to the server 11 to inform the information of the selected power supply device; and, after transmitting the selection message, the mobile phone 15 transmits a pairing request in the time window W1.

Step 618, the server 11 determines that the selected power supply device is the mobile phone 13, and sends a pairing instruction to the mobile phone 13, the pairing instruction including the information of the mobile phone 15.

In step 620, the mobile phone 13 receives the pairing request from the mobile phone 15 in the time window W2 according to the received configuration command.

In this embodiment, the pairing request may include the source party indication information, so that when the mobile phone 13 receives the pairing request, it may determine whether the pairing request is derived from the mobile phone 15 according to the determination.

In this embodiment, after the mobile phone 15 sends the selection message to the server 11, the server 11 can send a configuration command to the mobile phone 13 in a short time under normal circumstances, so that there must be a certain overlap period between the time window W1 and the time window W2. Thereby, it is ensured that the mobile phone 13 can receive the pairing request from the mobile phone 15 and reduce the transmission time of the mobile phone 15 for the pairing request as much as possible to reduce the power consumption of the mobile phone 15.

Further, since the mobile phone 15 is a powered device, there is a higher risk of power failure. Therefore, after entering the time window W2, the mobile phone 13 can send a notification message to the mobile phone 15 through the server 11, so that the mobile phone 15 is based on the notification message. The time window W1 is started and the pairing request is started to be transmitted, thereby further shortening the transmission time of the pairing request by the mobile phone 15, and reducing the power consumption of the mobile phone 15.

In step 622, the mobile phone 13 and the mobile phone 15 implement near field matching.

In step 624, the mobile phone 13 wirelessly charges the mobile phone 15.

In this embodiment, as the transmission distance increases, wireless charging energy may have greater loss; therefore, the user of the mobile phone 13 and the mobile phone 15 may be guided as close as possible, thereby improving wireless charging efficiency and shortening the charging duration. Reduce energy loss. For example, any one of the mobile phone 13 and the mobile phone 15 can determine the relative positional relationship with the other party device, thereby guiding the user of the one of the party devices to the other party device. In the following, the mobile phone 15 is used to guide its user to the mobile phone 13 as an example to illustrate the boot process:

In an embodiment, the server 11 can transmit the geographic location of the mobile phone 13 to the mobile phone 15, and the mobile phone 15 can generate a relative positional relationship between the mobile phone 15 based on its geographic location and the geographic location of the mobile phone 13. For example, as shown in FIG. 7, assuming that the user of the mobile phone 15 selects the power supply device X1, and the power supply device X1 is the mobile phone 13, the mobile phone 15 can show the "navigation to go" option 74 shown in FIG. 9 and further in the mobile phone 15. When detecting that the option 74 is triggered, the mobile phone 15 may send a selection message for the mobile phone 13 to the server 11, and receive the geographic location of the mobile phone 13 returned by the server 11, so that according to the relative positional relationship between itself and the mobile phone 13, The navigation information to the mobile phone 13 is displayed to the user to guide the user to the mobile phone 13.

In particular, when the distance between the mobile phone 13 and the mobile phone 15 is relatively long, the near field pairing between the two parties may not be completed, or the transmission of the wireless charging energy is unstable although the near field pairing is completed. Then, the user of the mobile phone 15 can be navigated through the above embodiment, so that the mobile phone 13 and the mobile phone 15 are closer to each other, and the wireless charging process between the two is optimized.

In another embodiment, when the near field pairing is completed between the mobile phone 13 and the mobile phone 15, and the mobile phone 15 can sense the wireless charging energy emitted by the mobile phone 13, the mobile phone 15 can generate two according to the strength and direction of the wireless charging energy. The relative positional relationship between the users and guiding the user of the mobile phone 15 to the mobile phone 13 to improve the wireless charging efficiency.

FIG. 10 is a schematic diagram of another interaction for implementing a wireless charging solution according to an exemplary embodiment of the present application. As shown in FIG. 10, the mobile phone 13 as the power supply device 21, the mobile phone 15 as the power receiving device, and the server 11 are taken as an example. The interaction process can include the following steps:
