Description

Technical Field

[0001] The present disclosure relates to the field of wireless charging technologies, and in particular, to a wireless charging method and apparatus, a foldable screen electronic device, and a storage medium. Background Art

[0002] Currently, with the user's demand for the display screen size, the display screen size of foldable screen electronic devices is getting larger and larger. Some foldable screen electronic devices also adopt foldable screens to meet the needs of some users. Correspondingly, the power consumption of foldable screen electronic devices also increases accordingly. Therefore, wireless charging technology can be applied to foldable screen electronic devices, making the charging and battery life of foldable screen electronic devices very convenient.

[0003] In practical applications, foldable screen electronic devices will continue to use a single receiving coil design. For example, the receiving coil is disposed on the rear case of the foldable screen electronic device. In this way, when the foldable screen electronic device has a charging requirement, the user can attach the rear case to the wireless charging device to wirelessly charge the foldable screen electronic device. When the user attaches the external display screen to the wireless charging device or the foldable screen is unfolded and there is no receiving module in the attachment area, since the distance between the receiving coil and the transmitting coil becomes larger, the receiving efficiency of the receiving coil becomes lower or even unable to charge, thus prolonging the charging time and reducing the user experience.

[0091] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The exemplary embodiments described below do not represent all embodiments consistent with the present disclosure. On the contrary, they are only examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0092] Currently, with the user's demand for the display screen size, the display screen size of foldable screen electronic devices is getting larger and larger. Some foldable screen electronic devices also adopt foldable screens to meet the needs of some users. Correspondingly, the power consumption of foldable screen electronic devices also increases. Therefore, wireless charging technology can be applied to foldable screen electronic devices, making the charging and battery life of foldable screen electronic devices very convenient.

[0093] In actual applications, foldable screen electronic devices will continue to use a single receiving coil design. For example, the receiving coil is set on the rear case of the foldable screen electronic device. In this way, when the foldable screen electronic device has a charging requirement, the user can attach the rear case to the wireless charging device to wirelessly charge the foldable screen electronic device. When the user attaches the external display to the wireless charging device or when the foldable screen is unfolded and there is no receiving module in the attachment area, since the distance between the receiving coil and the transmitting coil becomes larger, the receiving efficiency of the receiving coil becomes lower or even unable to charge, thus prolonging the charging time and reducing the user experience.

[0094] To solve the above technical problems, embodiments of the present disclosure provide a foldable screen electronic device provided with two receiving modules, and hereinafter, the two receiving modules will be respectively referred to as the first receiving module and the second receiving module for distinction. In this embodiment, the foldable screen electronic device includes two display screens. After the foldable screen is closed, the display screen that can be used is called the external display screen, and the hidden display screen is called the internal display screen. Or, when the foldable screen is unfolded, the display screen with a larger area is the internal display screen, and the display screen with a smaller area is the external display screen. It should be noted that the unfolding of the foldable screen may include complete unfolding and partial unfolding. Among them, complete unfolding means that two parts (or multiple parts) of the foldable screen form a plane, and partial unfolding means that there is a certain angle between two parts of the foldable screen, and the angle is greater than 90 degrees. It should be noted that the closing of the foldable screen may include complete closing and partial closing. Among them, complete closing means that two parts of the foldable screen are close to (or parallel to) each other, and partial closing means that there is a certain angle between two parts of the foldable screen, and the angle is less than 90 degrees. For the convenience of description, the subsequent embodiments will be described with the foldable screen unfolded in a completely unfolded state and the foldable screen closed in a completely closed state.

[0095] Among them, it should be noted that being close means that the distance between the electronic device and the wireless charging device is less than or equal to a preset distance threshold (such as 2 cm, adjustable). In one example, when the distance between the electronic device and the wireless charging device is zero, at this time, the electronic device is attached to the wireless charging device, and the current charging efficiency is the highest.

[0096] For the convenience of description, in the case where the foldable screen is in the closed state and the two parts of the foldable screen are close to each other, the side away from the external display screen is used as the first side, and the side where the external display screen is located is used as the second side. In the case where the foldable screen is in the closed state and the two parts of the foldable screen are external (i.e., parallel), the side where the secondary display screen is located is used as the first side, and the side where the main display screen is located is used as the second side.

[0097] In this embodiment, the receiving coil (RX1) in the first receiving module can be arranged on the first side, and the receiving coil (RX2) in the second receiving module can be arranged on the second side.

[0098] FIG. 1 is a schematic diagram of a foldable screen electronic device shown according to an exemplary embodiment. Refer to Figures 1(a) to 1(c) :

[0099] FIG. 1(a) shows the back effect when the foldable screen of the foldable screen electronic device is unfolded. Among them, the receiving coil RX1 is arranged on the first side of the electronic device, the receiving coil RX2 is arranged on the second side of the electronic device, and RX1 and RX2 are represented by thick dashed lines to indicate that they are arranged on the corresponding side. In addition, the external display screen is arranged on the second side.

[0100] Figure 1(b) shows the front view of the folding screen when it is unfolded in the folding screen electronic device, where the built-in display screen is presented on the front. The receiving coils RX1 and RX2 are represented by thin dashed lines to indicate that they are disposed in the corresponding folding parts and on the side away from the built-in display screen.

[0101] Figure 1(c) shows the effect when the folding screen of the folding screen electronic device is closed. An external display screen is provided on the second side of the electronic device, and the receiving coil RX2 is disposed on the second side; the receiving coil RX1 is provided on the first side of the electronic device. The effect of the receiving coil RX2 disposed on the second side of the folding screen electronic device. In practical applications, the setting positions of the receiving coils RX1 and RX2 on the first side and the second side are not specifically limited. Considering the user's usage habits and charging efficiency, in one example, the centers of the receiving coils RX1 and RX2 are aligned, that is, when looking at the external display screen (Z-axis direction) from the back shell of the folding screen electronic device in the closed state of the folding screen, the central projections of the receiving coil RX1 and the receiving coil RX2 coincide.

[0102] Figure 2 It is a circuit schematic diagram of a folding screen electronic device shown according to an exemplary embodiment. Refer to Figure 2 , this folding screen electronic device includes a processor, a first receiving module, and a second receiving module; the processor is respectively connected to the first receiving module and the second receiving module, and can respectively control the switches of the first receiving module and the second receiving module, so as to select the first receiving module to charge the battery, the second receiving module to charge the battery, or both receiving modules to charge the battery simultaneously. In this way, in this embodiment, by providing the first receiving module and the second receiving module on the folding screen electronic device, when one side of the folding screen electronic device is close to the wireless charging device, at least one receiving module can be selected to wirelessly charge the battery of the electronic device, which can improve the charging efficiency and shorten the charging time. And there is no need for the user to select a specified side for charging, which is beneficial to improving the user experience.

[0103] Continue to refer to Figure 2 , in this embodiment, the folding screen electronic device further includes a spatial attitude sensor.

[0104] In one example, the spatial attitude sensor can be one or more of a gravity sensor, an acceleration sensor, or a gyroscope, which can be selected according to the specific scenario. The spatial attitude sensor obtains the spatial attitude data of the folding screen electronic device and sends the spatial attitude data to the processor. The processor can obtain the opening and closing state and / or placement attitude of the folding screen electronic device based on the spatial attitude data. In this way, the processor can use at least one of the first receiving module and the second receiving module to charge the battery of the folding screen electronic device according to the opening and closing state and / or placement attitude of the folding screen electronic device, thereby achieving high-efficiency charging and shortening the charging time as much as possible.

[0105] In another example, the spatial attitude sensor may also be a distance sensor. When the wireless charging device is large in size, the distance sensor may be arranged at the top of the folding screen electronic device; when the wireless charging device is small in size, the distance sensor may be arranged near one of the receiving coils RX.

[0106] Take the distance sensor set on one side of the external display screen (i.e., the second side of the folding screen electronic device) as an example, the effect is shown in the distance sensor 1 in Figure 1 (a). When the first side of the folding screen electronic device is close to the wireless charging device, the distance sensor cannot detect the distance value (which can be indicated by an invalid mark) or the detected distance value is infinite (the default value is infinite when it exceeds its detection range). The processor can determine that the distance sensor is far away from the wireless charging device based on the distance value being greater than the distance threshold, that is, it can be determined that the placement posture of the folding screen electronic device is that the first side of the folding screen electronic device is close to the wireless charging device. When the second side of the folding screen electronic device is close to the wireless charging device, the distance sensor can detect that the distance value is less than the distance threshold. At this time, the processor can determine that the distance sensor is close to the wireless charging device based on the distance value being less than the distance threshold, that is, it can be determined that the placement posture of the folding screen electronic device is that the second side of the folding screen electronic device is close to the wireless charging device.

[0107] At the same time, when the distance sensor is set on one side of the built-in display screen, the effect is shown as the distance sensor 2 in Figure 1(b). When the folding screen is closed, the distance value detected by the distance sensor is less than the distance threshold, and when the folding screen is unfolded, the distance value detected by the distance sensor exceeds the distance threshold, so that the opening and closing state of the folding screen can be determined based on the distance data.

[0108] Based on the above folding screen electronic device, the present disclosure provides a wireless charging method. Figure 3 is a flow chart of a wireless charging method according to an exemplary embodiment. Figure 3 , a wireless charging method, comprising step 31 and step 32, wherein:

[0109] In step 31, after handshaking and communicating with the wireless charging device, obtain the charging types supported by the wireless charging device.

[0110] In this embodiment, the wireless charging device will send pulse detection signals at a set period (in a broadcast manner) according to the internally set wireless charging protocol, such as the Qi protocol or the A4WP protocol. The pulse detection signals are used to detect whether the foldable screen electronic device to be charged has been placed on this wireless charging device. Taking the wireless charging protocol as the Qi protocol as an example, the pulse detection signal can be the power signal in the Ping Phase.

[0111] In this embodiment, after the foldable screen electronic device is placed on the wireless charging device, the first receiving module and / or the second receiving module in the foldable screen electronic device can receive the above-mentioned pulse detection signals. In response to receiving the above-mentioned pulse detection signals, the first receiving module and / or the second receiving module can send pulse response signals to the wireless charging device. After receiving the above-mentioned pulse response signals, the wireless charging device can determine that there is a foldable screen electronic device placed above it, thus completing the handshaking process.

[0112] After the handshaking communication, the foldable screen electronic device can determine the charging types supported by the wireless charging device according to the used wireless charging protocol or the communication data during the handshaking process. The charging types can include at least one of the following: resonant charging type and coupled charging type. The resonant charging type means that the wireless charging device can radiate energy by emitting electromagnetic waves with a preset resonant frequency. At this time, the resonant frequencies of the first receiving module and the second receiving module need to match it; the coupled charging type means that the wireless charging device can emit electromagnetic waves with different frequencies to radiate energy. At this time, the receiving coil only needs to be within the radiation range.

[0113] For the wireless charging device, after the handshaking process is completed, the wireless charging device can control the transmitting coil to radiate energy to perform the subsequent wireless charging process. The specific content can refer to the relevant wireless charging protocol and will not be elaborated here.

[0114] In step 32, based on the charging type, select the first receiving module and / or the second receiving module to charge the battery of the foldable screen electronic device.

[0115] In this embodiment, after the processor obtains the charging types supported by the wireless charging device, where the charging types include at least one of the resonant charging type and the coupled charging type, it can select at least one of the first receiving module and the second receiving module to charge the battery, including:

[0116] In one example, when the charging type is the resonant charging type, since the resonant charging method has lower requirements for distance compared to the inductive charging method in terms of distance and shielding, etc., the processor can select the first receiving module and the second receiving module to charge the battery of the foldable screen electronic device simultaneously. The working principle of resonant wireless charging can refer to the related technology and will not be elaborated here.

[0117] In another example, when the charging type is the inductive charging type, the processor can select either the first receiving module or the second receiving module to charge the battery of the foldable screen electronic device alone. The selection principle is to choose a charging module closer to the wireless charging device to charge the battery of the foldable screen electronic device.

[0118] In this example, the processor selects the receiving module according to the opening and closing state of the foldable screen electronic device. Refer to Figure 4 :

[0119] In step 41, the processor can obtain the spatial attitude data collected by the spatial attitude sensor in the foldable screen electronic device.

[0120] In step 42, the processor can obtain the opening and closing state of the foldable screen electronic device according to the spatial attitude data; where the opening and closing state includes the foldable screen being closed or the foldable screen being unfolded. For example, taking the spatial attitude data including distance data (which can be the distance value collected by the distance sensor 2 in Fig. 1(b)) as an example, this distance data refers to the distance value between two folded parts of the electronic device. Refer to Figure 5 , in step 51, the processor can obtain the distance data in the spatial attitude data of the foldable screen electronic device. In step 52, when the distance data is less than a preset distance threshold, the processor can determine that the foldable screen is in the closed state, as shown in Figure 6 ; or, when the distance data exceeds the preset distance threshold, the processor can determine that the foldable screen is in the unfolded state, as shown in Fig. 1(b).

[0121] In step 43, when the opening and closing state is that the foldable screen is closed, obtain the placement attitude of the foldable screen electronic device; where the placement attitude is that the first side of the foldable screen electronic device is close to the wireless charging device, or the placement attitude is that the second side of the foldable screen electronic device is close to the wireless charging device.

[0122] Taking the spatial attitude data including gravity data as an example, the processor can obtain the placement attitude of the foldable screen electronic device. Refer to Figure 7, in step 71, the processor may obtain the gravity data in the spatial attitude data, as well as the gravity component of the gravity data on the Z-axis. Here, the Z-axis is perpendicular to the folding screen and points from the first side to the second side when the folding screen is closed, and the effect of the Z-axis is shown in FIG. 1(c). In step 72, when the gravity component exceeds a preset component threshold and points in the negative direction of the Z-axis, it is determined that the placement attitude is that the first side of the folding screen electronic device is close to the wireless charging device; or, when the gravity component exceeds a preset component threshold and points in the positive direction of the Z-axis, it is determined that the placement attitude is that the second side of the folding screen electronic device is close to the wireless charging device.

[0123] Refer to Figure 8 , the spatial attitude sensor can obtain the gravity G and the tilt angle of the folding screen electronic device. At this time, the gravity component G1 of the gravity G on the Z-axis can be obtained, and the calculation method can refer to the related technology and will not be limited here. Then, the processor can compare the magnitude of the gravity component G1 with the gravity threshold Gn. When the gravity component G1 is greater than the gravity threshold Gn and points in the negative direction of the Z-axis, the processor can determine that the placement attitude is that the first side is close to the wireless charging device, and the effect is as Figure 8 shown; when the gravity component G1 is greater than the gravity threshold Gn and points in the positive direction of the Z-axis, the processor can determine that the placement attitude is that the second side is close to the wireless charging device (not shown in the figure); when the gravity component G1 is less than the gravity threshold Gn, the processor can determine that the attitude is other attitudes.

[0124] Taking the spatial attitude data including distance data (which can be the distance value collected by the distance sensor 1 in FIG. 1(a)) as an example, this distance data refers to the distance value between the electronic device and the wireless charging device. The processor can obtain the placement attitude of the folding screen electronic device. Refer to Figure 9 , in step 91, the processor can obtain the distance data between the two folding parts of the folding screen electronic device. In step 92, when the distance data is less than a preset distance threshold, the processor can determine that the placement attitude is that the first side of the folding screen electronic device is close to the wireless charging device, and the effect is shown in FIG. 10(a); or, when the distance data exceeds the preset distance threshold, it is determined that the processor can determine that the placement attitude is that the second side of the folding screen electronic device is close to the wireless charging device, and the effect is shown in FIG. 10(b).

[0125] Continue to refer to Figure 4, in step 44, when the first side of the foldable screen electronic device is close to the wireless charging device in the placement posture, the first receiving module is selected to charge the battery of the foldable screen electronic device; when the second side of the foldable screen electronic device is close to the wireless charging device in the placement posture, the second receiving module is selected to charge the battery of the foldable screen electronic device. In this example, by selecting the receiving module close to the wireless charging device to charge the battery, the distance between the transmitting coil and the receiving coil in the wireless charging device is relatively small, which is beneficial to improving the charging efficiency and shortening the charging time.

[0126] In another example, when the processor can also obtain a posture other than the first side of the foldable screen electronic device being close to the wireless charging device and the second side of the foldable screen electronic device being close to the wireless charging device, the processor can turn off the first receiving module and the second receiving module at this time to stop charging the battery. In practical applications, the processor can also generate a reminder message to present to the user to remind the user that the current placement position is inappropriate and it is recommended to re-place the foldable screen electronic device.

[0127] In yet another example, when the processor can also obtain a placement posture other than the first side of the foldable screen electronic device being close to the wireless charging device and the second side of the foldable screen electronic device being close to the wireless charging device, the processor can perform the following processing at this time. See Figure 11 , in step 111, the processor can turn on the first receiving module and the second receiving module. In step 112, the processor can respectively obtain the receiving powers of the first receiving module and the second receiving module. Considering that when the receiving coil is relatively close to the transmitting coil, its receiving function is usually relatively large. Therefore, in step 113, the processor can select the receiving module with a larger receiving power to charge the battery of the foldable screen electronic device, and at the same time turn off the receiving module with a smaller receiving power.

[0128] So far, in the embodiments of the present disclosure, after handshaking and communicating with the wireless charging device, the charging types supported by the wireless charging device can be obtained; then, based on the charging types, the first receiving module and / or the second receiving module are selected to charge the battery of the foldable screen electronic device. In this way, by providing the first receiving module and the second receiving module on the foldable screen electronic device in this embodiment, when one side of the foldable screen electronic device is close to the wireless charging device, at least one receiving module can be selected to wirelessly charge the battery of the electronic device, which can improve the charging efficiency and shorten the charging time. And there is no need for the user to select a specified side for charging, which is beneficial to improving the user experience.

[0129] The above wireless charging method is described below in combination with a scenario. See Figure 12When the foldable screen electronic device is placed on the wireless charging device for charging, the foldable screen electronic device shakes hands and communicates with the wireless charging device. According to the type of handshake communication protocol, the charging types supported by the wireless charging device can be obtained. For example, when the wireless charging protocol is A4WP, the wireless charging device supports resonant charging; when the wireless charging protocol is Qi, the wireless charging device supports inductive charging.

[0130] If it is the resonant charging type, the first receiving module and the second receiving module are simultaneously turned on, and the two receiving modules charge the battery of the foldable screen electronic device at the same time.

[0131] If it is the inductive charging type, sensor data is obtained, and the opening and closing state of the foldable screen electronic device is obtained according to the sensor data.

[0132] If the foldable screen is closed, the placement posture of the foldable screen electronic device is obtained. Taking the sensor as an A+G sensor as an example, when the gravity component exceeds the component threshold and is in the negative direction of the Z axis, it is determined that the first side (one side of the back shell) of the foldable screen electronic device is close to the wireless charging device, and the first receiving module is used to charge the battery; when it is in the positive direction of the Z axis, it is determined that the second side (one side of the display screen) of the foldable screen electronic device is close to the wireless charging device, and the second receiving module is used to charge the battery.

[0133] If the foldable screen is unfolded, the receiving powers of the first receiving module and the second receiving module are obtained. When the receiving power of the first receiving module is greater than the receiving power of the second receiving module, the first receiving module is selected to charge the battery; when the receiving power of the second receiving module is greater than the receiving power of the first receiving module, the second receiving module is selected to charge the battery.
