Please refer to the drawings, where the same component symbols represent the same components. The principle of the present invention is illustrated by implementation in a suitable computing environment. The following description is based on the illustrated specific embodiments of the present invention, which should not be construed as limiting other specific embodiments of the present invention that are not detailed here.

Please refer to FIG. 1. FIG. 1 is a first schematic flowchart of a wireless charging request method according to an embodiment of the present application. The wireless charging request method can be applied to a wireless charging receiving device. The flow of the wireless charging request method may include:

In 101, a light detection signal is emitted outward.

In 101 of the embodiment of the present application, the wireless charging receiving device may emit a light detection signal to the outside. In one embodiment, the light detection signal may be invisible light such as infrared light.

In some embodiments, the wireless charging transmitting device may be installed on the ceiling or wall of the usage environment (such as a room). As shown in FIG. 2, taking the wireless charging transmitting device 20 installed on the ceiling of the room as an example. The wireless charging receiving device 10 (such as a smart phone or a tablet computer) can emit a light detection signal to the outside. After multiple reflections, the light detection signal is received by the wireless charging and transmitting device 20. After receiving the light detection signal, the wireless charging transmitting device 20 may first determine the angle of incidence of the light detection signal, and then determine the angle of emission of the light response signal to be transmitted according to the angle of incidence of the light detection signal. After that, the wireless charging transmitting device 20 can transmit an optical response signal outward according to the determined transmitting angle. According to the principle of reversible optical path, the optical response signal can be received by the wireless charging receiving device 10, as shown in FIG.

At 102, an optical response signal corresponding to the optical detection signal is received from the wireless charging transmitting device.

For example, after transmitting the light detection signal outward, the wireless charging receiving device receives the optical response signal from the wireless charging transmitting device.

In 103, the incident angle of the optical response signal is obtained, and the first target emission angle is determined according to the incident angle of the optical response signal.

For example, after receiving the optical response signal, the wireless charging receiving device may acquire the incident angle of the optical response signal, and determine the first target emission angle according to the incident angle of the optical response signal.

In 104, according to a first target emission angle, a target optical signal is emitted, the target optical signal carrying a charging request, the charging request is used to instruct the wireless charging transmitting device to send optical charging to the wireless charging receiving device according to the emitting angle of the optical response signal signal.

For example, after acquiring the first target emission angle, the wireless charging receiving device may emit the target optical signal outward according to the first target emission angle. For example, as shown in FIG. 4, the wireless charging receiving device 10 determines the first target emission angle according to the incident angle of the light response signal, and emits the target optical signal outward according to the first target emission angle. Wherein, the target optical signal carries a charging request, and the charging request is used to instruct the wireless charging transmitting device to send the optical charging signal to the wireless charging receiving device according to the emission angle of the optical response signal, so that the wireless charging receiving device can be wirelessly charged. Similarly, according to the principle of reversible optical path, the target optical signal can be received by the wireless charging and transmitting device 20. After receiving the target optical signal, the wireless charging transmitting device 20 can transmit an optical charging signal to the wireless charging receiving device according to the emission angle of the optical response signal, so as to wirelessly charge the wireless charging receiving device.

It can be understood that, in this embodiment, the wireless charging receiving device may emit a light detection signal outward, and after receiving the optical response signal of the light detection signal from the wireless charging transmitting device, the wireless charging receiving device may determine the light Respond to the incident angle of the signal, and determine the first target emission angle according to the incident angle. Thereafter, the wireless charging receiving device may transmit the target optical signal according to the first target emission angle to request the wireless charging transmitting device to emit the optical charging signal according to the emission angle of the optical response signal. Since this embodiment can use the optical signal to request the wireless charging transmitting device to transmit the optical charging signal. Therefore, the distance between the wireless charging receiving device and the wireless charging transmitting device can be relatively long, that is, this embodiment is beneficial to realize long-distance wireless charging.

Please refer to FIG. 5, which is a second schematic flowchart of a wireless charging request method according to an embodiment of the present application. The wireless charging request method can be applied to a wireless charging receiving device. The flow of the wireless charging request method may include:

In 201, when it is detected that it is located in a target geographic location, the wireless charging receiving device acquires a historical transmission angle corresponding to the target geographic location, where the historical transmission angle is an outward transmission recorded by the wireless charging receiving device carrying a charging request The target geographic location is the geographic location recorded by the wireless charging receiving device using the optical signal for wireless charging.

For example, a wireless charging receiving device can obtain its geographic location information. When it is detected that the wireless charging receiving device is located in the target geographic location, the wireless charging receiving device may obtain the historical transmission angle corresponding to the target geographic location. Wherein, the target geographic location is the geographic location recorded by the wireless charging receiving device and using the optical signal to perform wireless charging. The historical emission angle is the angle recorded by the wireless charging receiving device to emit the optical signal carrying the charging request outward.

For example, a wireless charging and transmitting device that uses optical signals for wireless charging is installed in the office of the user company, and the user has used the optical signal emitted by the wireless charging and transmitting device for charging when in the company. When using optical signals for wireless charging, the wireless charging receiving device can record corresponding geographic location information and determine the geographic location information as the target geographic location. Then, when located in the target geographic location, the wireless charging receiving device can obtain the historical transmission angle corresponding to the target geographic location. Wherein, the historical transmission angle is the angle recorded by the wireless charging receiving device to transmit the optical signal carrying the charging request outward. For example, each time a light detection signal is emitted outward and an optical response signal from a wireless charging transmitting device is received, the wireless charging receiving device can determine the incident angle of the optical response signal, and according to the incident angle of the optical response signal, An emission angle is determined, and an optical signal carrying a charging request is emitted according to the emission angle. Then, when the wireless charging receiving device transmits the optical signal carrying the charging request, the wireless charging receiving device can record the emission angle of the optical signal carrying the charging request and determine it as the historical emission angle.

In 202, the wireless charging receiving device emits the light detection signal outwards at a plurality of different angles, where the plurality of different angles include historical emission angles.

For example, as shown in FIG. 6, the wireless charging receiving device 10 may include an infrared light emitting end 11 and an infrared light receiving end 12. Then, after the wireless charging receiving device 10 is located at the target geographic location and the historical emission angle is obtained, the wireless charging receiving device 10 can transmit multiple infrared light detection signals outward through its infrared light emitting end 11 at multiple different angles , For detecting possible wireless charging and transmitting equipment around. Among them, the multiple different angles include historical emission angles.

After the wireless charging receiving device 10 emits multiple infrared light detection signals, these signals will be reflected after encountering external obstacles. For example, as shown in FIG. 6, one of the multiple infrared light detection signals is received by the infrared light receiving terminal 22 of the wireless charging and transmitting device 20 after multiple reflections. After receiving the infrared light detection signal from the wireless charging reception device, the wireless charging transmitter device can determine the incident angle of the infrared light detection signal, and then determine the infrared light response to be emitted according to the incident angle of the infrared light detection signal The angle at which the signal is emitted. After that, the wireless charging transmitting device 20 can transmit an infrared light response signal to the outside through the infrared light emitting terminal 21 according to the determined emission angle. According to the characteristics of the optical path transmission, the transmission path of the infrared light response signal will be parallel to the received infrared light detection signal, and the infrared light response signal may be received by the infrared light receiving end 12 of the wireless charging receiving device.

In some embodiments, the light receiving ends (such as infrared light receiving ends) of the wireless charging transmitting device and the wireless charging receiving device may include an angle sensor (such as a photoelectric angle sensor, etc.), and the angle sensor may be used to detect the incident angle of the light signal . Alternatively, the light receiving ends (such as infrared light receiving ends) of the wireless charging receiving device and the wireless charging transmitting device may be disposed in a cavity, and the cavity may be a cuboid cavity or a cubic cavity. As shown in FIG. 7, the cavity may have five solid surfaces, for example, A, B, C, D, and E, where A and B are two opposite sides of the cavity (left and right sides in FIG. 7) ), Surface C and surface D are opposite sides of the cavity (front and rear sides in FIG. 7), and surface E is the bottom surface of the cavity. The light receiving end may be provided on the bottom surface E. There can be many sensors on the A, B, C, D, and E surfaces. These sensors can detect light signals (such as infrared light). For example, when an optical signal is incident from outside the cavity, the optical signal first hits point a on the A surface, and is reflected by the point a to be received by the light receiving end provided on the bottom surface E. point. Then, the incident angle of the optical signal can be calculated according to the positional relationship between point a and point e. For example, the incident angle of the optical signal may be the angle between the line segment ae and the bottom surface E in space.

In one embodiment, the light emitting end of the wireless charging transmitting device and the wireless charging receiving device may include a rotatable structure, so that the light emitting end can rotate within a certain angle range, so that the light emitting end can be selected from different Angles emit light signals (such as light detection signals, light response signals, light charging signals, etc.). For example, as shown in FIG. 8, the light emitting end can be rotated from position H to position I, or from position I to position J under the rotation of the rotatable structure. As can be seen from FIG. 8, the emission angles of the optical signals emitted by the light emitting end at positions H, I, and J can be different from each other, so that the light emitting end can emit light signals from different angles.

In 203, the wireless charging receiving device receives an optical response signal corresponding to the light detection signal from the wireless charging transmitting device, where the optical response signal carries the description information of the corresponding wireless charging transmitting device.

For example, as shown in FIG. 6, after the wireless charging transmitting device 20 transmits an infrared light response signal to the outside, the infrared light receiving terminal 12 of the wireless charging receiving device 10 may receive the infrared light response signal. Wherein, the infrared light response signal carries description information of the wireless charging and transmitting device.

In one embodiment, the description information of the wireless charging transmitting device may be information such as device identification, maximum transmission power, and the like.

In 204, the wireless charging receiving device acquires the incident angle of the light response signal, and determines the first target emission angle according to the incident angle of the light response signal.

For example, after receiving the infrared light response signal, the wireless charging receiving device may first determine the incident angle of the infrared light response signal. Thereafter, the wireless charging receiving device may determine the first target emission angle according to the incident angle of the infrared light response signal.

In 205, the wireless charging receiving device generates and displays a corresponding charging icon according to the description information of the wireless charging transmitting device.

For example, after determining the first target transmission angle, the wireless charging receiving device may generate a corresponding charging icon according to the description information of the wireless charging transmitting device, and display it on the display interface of the wireless charging receiving device for the user to view.

In 206, when receiving the user's selection operation of the charging icon, the wireless charging receiving device emits a target optical signal according to the first target emission angle, the target optical signal carrying a charging request, the charging request is used to instruct the wireless charging transmitting device The optical charging signal is sent to the wireless charging receiving device according to the emission angle of the optical response signal.

For example, after generating the charging icon corresponding to the wireless charging transmitting device, when receiving the user's selection operation on the charging icon, the wireless charging receiving device may transmit the target infrared light signal according to the first target transmitting angle, as shown in FIG. 9 Show. Among them, the target infrared light signal carries a charging request. The charging request may be used to instruct the wireless charging transmitting device to send an infrared light charging signal to the wireless charging receiving device according to the emission angle of the infrared light response signal.

After receiving the target infrared light signal, the wireless charging transmitting device may send the infrared light charging signal to the wireless charging receiving device at the angle of emission of the infrared light response signal according to the charging request carried in the target infrared light signal. As shown in FIG. 9, the infrared light charging signal transmitted by the wireless charging transmitting device 20 can be received by the infrared light receiving end 12 of the wireless charging receiving device 10. For example, the infrared light charging signal may be infrared light emitted by a laser diode. The wireless charging receiving device may have a photovoltaic cell that can convert the light energy of infrared light into electrical energy, and use the converted electrical energy to charge the battery.

In other embodiments, in addition to using infrared light as the optical charging signal, an invisible laser or the like may also be used as the optical charging signal, which is not specifically limited in this embodiment.

In an embodiment, the wireless charging receiving device in 203 receiving the optical response signal corresponding to the optical detection signal from the wireless charging transmitting device may include:

The wireless charging receiving device receives the optical response signal corresponding to the target light detection signal from the wireless charging transmitting device, wherein the target light detecting signal is the earliest received light detecting signal by the wireless charging transmitting device.

For example, if the wireless charging receiving device transmits light detection signals from multiple different angles, and the wireless charging transmitting device can receive multiple light detection signals, then the wireless charging transmitting device can determine the earliest received light detection signal It is the target light detection signal, and determines the angle of incidence of the target light detection signal, and determines an emission angle according to the angle of incidence of the target light detection signal. Afterwards, the wireless charging receiving device may transmit the optical response signal outward according to the transmission angle. The wireless charging receiving device can receive the optical response signal.

It is understandable that the transmission path of the optical path of the light detection signal received by the wireless charging transmitting device at the earliest may be considered to be the shortest. Using the optical path with the shortest path for long-distance wireless charging can improve the efficiency of wireless charging.

In another embodiment, the wireless charging receiving device in 203 receiving the optical response signal corresponding to the optical detection signal from the wireless charging transmitting device may include:

The wireless charging receiving device receives the optical response signal corresponding to the target light detection signal from the wireless charging transmitting device, wherein the target light detecting signal is the signal with the strongest energy among the light detecting signals received by the wireless charging transmitting device.

For example, if the wireless charging and receiving device emits light detection signals from multiple different angles, and the wireless charging and transmitting device can receive multiple light detection signals, then the wireless charging and transmitting device can convert the energy in the received multiple light detection signals The strongest light detection signal is determined as the target light detection signal, and the incident angle of the target light detection signal is obtained, and an emission angle is determined according to the incident angle of the target light detection signal. Afterwards, the wireless charging transmitting device may transmit the optical response signal outward according to the transmitting angle. The wireless charging receiving device can receive the optical response signal.

It can be understood that the optical path transmission path of the light detection signal with the strongest energy can be regarded as the transmission path with the smallest energy loss. Using the optical path with the smallest energy loss for remote wireless charging can also improve the efficiency of wireless charging.

In one embodiment, the description information of the wireless charging transmitting device carried in the optical response signal in 203 may include at least the maximum transmission power of the wireless charging transmitting device.

Then, the wireless charging receiving device in 205 generates and displays the corresponding charging icon according to the description information of the wireless charging transmitting device, which may include:

When receiving multiple optical response signals from multiple wireless charging transmitting devices, the wireless charging receiving device generates respective charging icons according to the description information of each wireless charging transmitting device;

The wireless charging receiving device arranges and displays all charging icons according to the order of the maximum transmission power of the wireless charging transmitting device from large to small.

For example, the wireless charging receiving device transmits multiple optical detection signals outward. The two optical detection signals in the multiple optical detection signals are respectively received by two different wireless charging transmitting devices. For example, the first light detection signal is received by the first wireless charging transmitting device, and the second light detection signal is received by the second wireless charging transmitting device. Then, the wireless charging receiving device may receive the first optical response signal transmitted by the first wireless charging transmitting device and the second optical response signal transmitted by the second wireless charging transmitting device.

After receiving the first optical response signal, the wireless charging receiving device may generate a first charging icon corresponding to the first wireless charging transmitting device according to the description information carried in the first optical response signal. After receiving the second optical response signal, the wireless charging receiving device may generate a second charging icon corresponding to the second wireless charging transmitting device according to the description information carried by the second optical response signal.

After that, the wireless charging receiving device may arrange the first charging icon and the second charging icon according to the order of the maximum transmission power of the first wireless charging transmitting device and the second wireless charging transmitting device from large to small, and display it to the user for viewing .

It is understandable that all charging icons are displayed in order of maximum transmission power from large to small for the user to view, which can make the user clearly understand which wireless charging transmission devices have higher transmission power, which is convenient for the user according to the wireless charging transmission device To select the specific wireless charging transmitter device to obtain the optical charging signal, thereby improving the flexibility of remote wireless charging. For example, if the maximum transmission power of the first wireless charging transmitting device is greater than the maximum transmitting power of the second wireless charging transmitting device, then the user can trigger the selection operation of the first charging icon and obtain the optical charging signal from the first wireless charging transmitting device .

Please refer to FIG. 10, which is a schematic flowchart of a wireless charging method according to an embodiment of the present application. The wireless charging method can be applied to a wireless charging transmitting device. The flow of the wireless charging method may include:

That is, the wireless charging transmitting device may receive the light detection signal from the wireless charging receiving device.

In 302, the incident angle of the light detection signal is acquired.

For example, after receiving the light detection signal, the wireless charging and transmitting device may determine the incident angle of the light detection signal.

In 303, the second target emission angle is determined according to the incident angle of the light detection signal.

In 304, according to the second target emission angle, an optical response signal corresponding to the optical detection signal is emitted.

For example, 303 and 304 may include:

After determining the incident angle of the light detection signal, the wireless charging transmitting device may determine the second target emitting angle according to the incident angle. Afterwards, the wireless charging transmitting device may transmit the optical response signal outward according to the second target transmitting angle. Wherein, the optical response signal is used to respond to the optical detection signal of the wireless charging receiving device.

In 305, a target light signal is received from the wireless charging receiving device, and according to the target light signal, the light charging signal is emitted according to the emission angle of the light response signal.

For example, the optical response signal emitted by the wireless charging transmitting device may be received by the wireless charging receiving device, and after receiving the optical response signal, the wireless charging receiving device may transmit the target optical signal according to the incident angle of the optical response signal. The target optical signal can be received by the wireless charging and transmitting device. Wherein, the target optical signal may carry a charging request, and the charging request is used to instruct the wireless charging transmitting device to send the optical charging signal to the wireless charging receiving device according to the emission angle of the optical response signal. After receiving the target optical signal, the wireless charging transmitting device may transmit the optical charging signal according to the emission angle of the optical response signal according to the target optical signal. The optical charging signal may be received by the wireless charging receiving device to wirelessly charge the wireless charging receiving device.

Please refer to FIGS. 11 to 13, which are schematic diagrams of wireless charging scenarios provided by embodiments of the present application.

Please refer to FIG. 11, for example, a wireless charging transmitting device 20 is installed on the ceiling of a room. The wireless charging transmitting device 20 can transmit and receive infrared light. The wireless charging transmitting device can emit infrared light to remotely charge the wireless charging receiving device. In other places of the room (such as walls, floors, etc.), several reflecting devices for reflecting infrared light may be installed, for example, the room may include reflecting

After that, the wireless charging receiving device 10 may transmit the target infrared light signal according to the first target emission angle through its infrared light emitting end 11. According to the transmission characteristics of the optical path, the transmission path of the target infrared light signal will be parallel to the infrared light response signal. As shown in FIG. 13, the target infrared light signal can be received by the infrared light receiving end 22 of the wireless charging and transmitting device 20 after being reflected by the reflecting

The target infrared light signal may carry a charging request, and the charging request is used to instruct the wireless charging transmitting device 20 to send an infrared light charging signal to the wireless charging receiving device 10 according to the emission angle of the optical response signal. After receiving the target infrared light signal, the wireless charging transmitting device 20 may transmit the infrared light charging signal according to the emission angle of the infrared light response signal according to the target infrared light signal. According to the transmission characteristics of the optical path, the transmission path of the infrared light charging signal will be consistent with the infrared light response signal (or the transmission path of the infrared light charging signal will be parallel to the target infrared light signal). The infrared light charging signal may be received by the wireless charging receiving device 10 to wirelessly charge the wireless charging receiving device 10.
