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 method provided by 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:

In 101, a light detection signal is emitted outward.

With the continuous development of technology, more and more electronic devices using wireless charging. Wireless charging refers to the transmission of electrical energy through non-conductive materials. In practical applications, wireless charging usually refers to the transmission of electrical energy through a certain spatial distance. At present, wireless charging technologies such as electromagnetic induction and magnetic field resonance are often used. However, in the related art, these wireless charging methods require that the wireless charging transmitting device and the wireless charging receiving device are close to each other. For example, the wireless charging method of electromagnetic induction needs to place the wireless charging receiving device on the base of the wireless charging transmitting device for wireless charging.

In 101 of this embodiment, the wireless charging transmitting device may transmit 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 10 installed on the ceiling of the room as an example. The wireless charging and transmitting device 10 can transmit a light detection signal to the outside. After multiple reflections, the light detection signal is received by the wireless charging receiving device 20 (such as a smartphone or a tablet computer). After receiving the light detection signal, the wireless charging receiving device 20 may first determine the incident angle of the light detection signal, and then determine the emission angle of the light response signal to be emitted according to the incident angle of the light detection signal. Thereafter, the wireless charging receiving device 20 may transmit an optical response signal outward according to the determined emission angle. According to the principle of reversible optical path, the optical response signal can be received by the wireless charging transmitting device 10, as shown in FIG.

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

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

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

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

In 104, according to the first target emission angle, the first optical charging signal is transmitted to wirelessly charge the wireless charging receiving device.

For example, after determining the first target emission angle, the wireless charging transmitting device may transmit the first optical charging signal outward according to the first target emission angle. For example, as shown in FIG. 4, the wireless charging transmitting device 10 determines the first target emission angle according to the incident angle of the light response signal, and emits the first light charging signal outward according to the first target emission angle. Similarly, according to the principle of reversible optical path, the first optical charging signal can be received by the wireless charging receiving device 20. After receiving the first optical charging signal, the wireless charging receiving device 20 can use the first optical charging signal to charge the battery. For example, the first 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.

It can be understood that, in this embodiment, the wireless charging transmitting device may emit a light detection signal outward, and after receiving the optical response signal of the light detecting signal from the wireless charging receiving device, the wireless charging transmitting 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. After that, the wireless charging transmitting device may transmit the optical charging signal according to the first target emission angle to wirelessly charge the wireless charging receiving device. Since this embodiment can use optical signals for wireless charging, the distance between the wireless charging transmitting device and the wireless charging receiving device can be relatively long, that is, this embodiment can realize long-distance wireless charging.

Please refer to FIG. 5, which is a second 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:

In 201, the wireless charging transmitting device transmits a light detection signal to the outside.

For example, as shown in FIG. 6, the wireless charging transmitting device 10 may include an infrared light transmitting end 11 and an infrared light receiving end 12. The wireless charging transmitting device 10 may first transmit infrared light detection signals through its infrared light emitting end 11.

The wireless charging receiving device 20 may also include an infrared light emitting end 21 and an infrared light receiving end 22. The infrared light detection signal emitted by the wireless charging transmitting device is received by the infrared light receiving terminal 22 of the wireless charging receiving device after multiple reflections. After receiving the infrared light detection signal, the wireless charging receiving device can first determine the incident angle of the infrared light detection signal, and then determine the emission angle of the infrared light response signal to be emitted according to the incident angle of the infrared light detection signal . After that, the wireless charging receiving device may 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 transmission, the transmission path of the infrared light response signal will be parallel to the infrared light detection signal, and the infrared light response signal can be received by the infrared light receiving end 12 of the wireless charging and transmitting 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 202, the wireless charging transmitting device receives the optical response signal corresponding to the optical detection signal from the wireless charging receiving device.

For example, after the wireless charging receiving device transmits an infrared light response signal to the outside, the infrared light receiving end of the wireless charging transmitting device may receive the infrared light response signal emitted by the wireless charging receiving device.

In 203, the wireless charging transmitting device determines 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 and transmitting device may first determine the incident angle of the infrared light response signal. After that, the wireless charging and transmitting device may determine the first target transmitting angle according to the incident angle of the infrared light response signal.

In 204, according to the first target emission angle, the wireless charging transmitting device transmits a first optical charging signal to wirelessly charge the wireless charging receiving device.

For example, after determining the first target emission angle, the wireless charging transmitting device may transmit the first infrared light charging signal according to the first target emission angle. The first infrared light charging signal may be received by the wireless charging receiving device, thereby wirelessly charging the wireless charging receiving device. For example, the first 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.

In 205, the wireless charging transmitting device obtains the output power, and the charging power of the wireless charging receiving device.

For example, in the process of transmitting the first infrared light charging signal to the wireless charging receiving device according to the first target emission angle to wirelessly charge the wireless charging receiving device, the wireless charging transmitting device may obtain its own output power and wireless charging The charging power of the receiving device.

In 206, according to the output power and the charging power, the wireless charging transmitting device obtains the power loss ratio during wireless charging.

For example, after acquiring the output power of the wireless charging transmitting device and the charging power of the wireless charging receiving device, the wireless charging transmitting device may obtain the power loss ratio during wireless charging according to the output power and the charging power.

For example, the output power of the wireless charging transmitting device is 10W, and the charging power of the wireless charging receiving device is only 2W, then the power loss of wireless charging is 8W, which can be considered to be mainly due to the first infrared light charging signal Attenuation loss during air transmission.

After acquiring the power loss ratio during wireless charging, the wireless charging transmitting device may detect whether the power loss ratio is greater than or equal to a preset threshold.

If it is detected that the power loss ratio during wireless charging is less than the preset threshold, then it can be considered that the loss of the first infrared light charging signal during air transmission is small, at which time the wireless charging transmitting device may continue to transmit the An infrared light charging signal to wirelessly charge the wireless charging receiving device.

If it is detected that the power loss ratio during wireless charging is greater than or equal to the preset threshold, it may be considered that the loss of the first infrared light charging signal during the air transmission is large, and it may enter 207 at this time.

In 207, if it is detected that the power loss ratio is greater than or equal to the preset threshold, the wireless charging transmitting device re-selects the emission angle of the optical charging signal.

For example, the output power of the wireless charging transmitting device is 10W, and the charging power of the wireless charging receiving device is only 2W, that is, the power loss of wireless charging is 8W, then the proportion of power loss during wireless charging is 80%. For example, the preset threshold is 65% or 70%. Then, since the power loss during wireless charging is 80% greater than the preset threshold, it can be considered that the power loss for wireless charging is large at this time. This can be considered to be mainly due to the excessive energy lost during the transmission of the optical charging signal. That is to say, when the infrared light charging signal is transmitted according to the first target emission angle, the transmission path of the infrared light charging signal is not a better path. In this case, the wireless charging transmitting device can re-select the emission angle of the infrared light charging signal.

For example, the wireless charging transmitting device may re-select one or more transmitting angles to transmit infrared light detection signals outward. If the wireless charging transmitter device can receive the infrared light response signal corresponding to one or more infrared light detection signals, then the wireless charging transmitter device can determine the incident angle of the corresponding infrared light response signal, and then determine the use angle according to the incident angle With regard to the emission angle of the light charging signal, that is, the wireless charging transmitter re-selects the emission angle of the light charging signal.

In 208, the wireless charging transmitting device transmits a second optical charging signal outward according to the reselected transmitting angle to wirelessly charge the wireless charging receiving device, wherein the transmitting angle of the second optical charging signal is different from the first optical charging The angle at which the signal is emitted.

For example, after re-selecting the emission angle of the optical charging signal, the wireless charging transmitting device may transmit the second infrared light charging signal outward according to the re-selected emission angle to wirelessly charge the wireless charging receiving device. The emission angle of the second infrared light charging signal is different from the emission angle of the first infrared light charging signal.

After transmitting the second infrared light charging signal, the wireless charging transmitting device can also monitor whether the power loss ratio during wireless charging is greater than or equal to a preset threshold. If yes, the wireless charging transmitting device can re-select a different emission angle to emit the optical charging signal to wirelessly charge the wireless charging receiving device until the wireless charging receiving device is wirelessly charged according to the optical charging signal transmitted at the selected emission angle The power loss ratio at the time is less than the preset threshold. If the power loss ratios corresponding to the optical charging signals emitted by the multiple charging angles selected by the wireless charging transmitting device are greater than or equal to the preset threshold, then the wireless charging transmitting device may select an emission angle with the smallest power loss ratio to emit the optical charging signal, To wirelessly charge the wireless charging receiving device.

In another embodiment, after the wireless charging transmitting device transmits the first infrared light charging signal according to the first target emission angle, the following process may be performed instead of performing the processes in 205 to 208 described above:

After transmitting the first optical charging signal outward, the wireless charging transmitting device monitors whether the first optical charging signal is blocked during transmission;

If blocking occurs, the wireless charging transmitting device re-selects the emission angle of the optical charging signal;

The wireless charging transmitting device transmits a third optical charging signal outward according to the reselected transmitting angle to wirelessly charge the wireless charging receiving device, wherein the transmitting angle of the third optical charging signal is different from the transmitting angle of the first optical charging signal .

For example, in the process of transmitting the first infrared light charging signal according to the first target emission angle to wirelessly charge the wireless charging receiving device, the wireless charging transmitting device may monitor whether the first infrared light charging signal is blocked during transmission . That is to say, the wireless charging transmitting device can monitor whether the first infrared light charging signal is blocked by an object on the transmission path during transmission, thereby causing the infrared light charging signal received by the wireless charging receiving device to be intermittent.

If it is detected that the first infrared light charging signal is not blocked during transmission, then the transmission path of the first infrared light charging signal may be considered to be superior, and the wireless charging transmitting device may continue to emit infrared light according to the first target emission angle The charging signal is given to the wireless charging receiving device.

If it is detected that the first infrared light charging signal is blocked during the transmission process, for example, during the process of the wireless charging transmitting device communicating with the wireless charging receiving device, the wireless charging receiving device notifies the wireless charging transmitting device of the received optical charging signal Intermittently. Then, it can be considered that the transmission path of the first infrared light charging signal is poor. In this case, the wireless charging transmitting device may re-select the emission angle of the infrared light charging signal, and transmit the third infrared light charging signal outward according to the re-selected emission angle to wirelessly charge the wireless charging receiving device, wherein, The emission angle of the third infrared light charging signal is different from the emission angle of the first infrared light charging signal.

In one embodiment, when the wireless charging transmitting device performs the above blocking, and then re-selects the emission angle of the optical charging signal, it may execute:

If blocking occurs, the wireless charging transmitting device counts the number of blocking occurrences;

When the number of blocking occurrences is greater than or equal to the preset value, the wireless charging transmitting device re-selects the emission angle of the optical charging signal.

For example, if the wireless charging transmitting device detects that the first infrared light charging signal is blocked during transmission, then the wireless charging transmitting device may further count the number of times that the blocking occurs, and detect that the number of times the blocking occurs is greater than or equal to the When setting the value, re-select the emission angle of the infrared light charging signal.

In an embodiment, when the wireless charging and transmitting device emits a light detection signal outward, it may perform:

The wireless charging transmitting device obtains a historical transmitting angle, and the historical transmitting angle is the transmitting angle when the wireless charging transmitting device has recorded the emitted light charging signal;

The wireless charging transmitting device emits the light detection signal outwards at multiple different angles, wherein the multiple different angles include historical emission angles.

For example, when the wireless charging transmitting device emits the optical charging signal outward, it can record the emission angle of the emitted optical charging signal, so that the wireless charging transmitting device can obtain the historical emission angle of the optical charging signal.

Then, when the light detection signal needs to be emitted outward to detect the wireless charging receiving device, the wireless charging transmitting device can emit the light detecting signal to multiple different angles, where the multiple different angles contain To the historical launch angle.

It can be understood that transmitting the light detection signal to the historical emission angle of the light charging signal can improve the efficiency of detecting the wireless charging receiving device. For example, in an office, users generally sit in their own seats, and the location where users place their mobile phones (wireless charging receiving devices) is also relatively fixed. Therefore, light detection signals are emitted according to the historical emission angles of previous light charging signals. It can improve the efficiency of the wireless charging transmitting device to detect the user's mobile phone.

In one embodiment, when the wireless charging transmitting device performs receiving the optical response signal corresponding to the optical detection signal from the wireless charging receiving device, it may execute:

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

For example, if the wireless charging transmitting device emits light detection signals from multiple different angles, and the wireless charging receiving device can receive multiple light detection signals, then the wireless charging receiving 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 transmitting device can receive the optical response signal.

It can be understood that the transmission path of the optical path of the light detection signal received by the wireless charging receiving 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, when the wireless charging transmitting device performs receiving the optical response signal corresponding to the optical detection signal from the wireless charging receiving device, it may execute:

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

For example, if the wireless charging and transmitting device emits light detection signals from multiple different angles, and the wireless charging and receiving device can receive multiple light detection signals, then the wireless charging and receiving 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 receiving device may transmit the optical response signal outward according to the transmission angle. The wireless charging transmitting 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.

Please refer to FIG. 9, which is another 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 receiving device. The flow of the wireless charging method may include:

In 301, a light detection signal is received from a wireless charging transmitting device.

For example, after the wireless charging transmitting device emits an optical detection signal outward, the optical detection signal may be received by the wireless charging receiving device after multiple reflections. That is, the wireless charging receiving device may receive the light detection signal from the wireless charging transmitting device.

In 302, the angle of incidence of the light detection signal is determined.

For example, after receiving the light detection signal, the wireless charging receiving 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 is emitted, and the optical response signal is used to respond to the optical detection signal.

For example, after determining the incident angle of the light detection signal, the wireless charging receiving device may determine the second target emission angle according to the incident angle. Afterwards, the wireless charging receiving device may emit an optical response signal outward according to the second target emission angle. Wherein, the optical response signal is used to respond to the optical detection signal of the wireless charging and transmitting device.

As shown in FIG. 11, according to the transmission characteristics of the optical path, the transmission path of the infrared light response signal will be parallel to the transmission path of the infrared light detection signal. The infrared light response signal can be received by the infrared light receiving end 12 of the wireless charging and transmitting device 10 after being reflected by the reflecting

devices

33, 34, 31 in sequence.
