DETAILED DESCRIPTION

[0069] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of charging devices and charging methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0070] Figure 1a FIG. 1 is a schematic diagram of a charging device structure according to an exemplary embodiment. Figure 1a As shown, the charging device includes:

[0071] The housing 10 has an opening;

[0072] The display screen 20 is installed at the opening and forms an accommodation space with the housing 10;

[0073] The wireless charging module 30 is located in the accommodating space and is arranged on the back of the display screen 20, and is configured to provide a charging signal to the device to be charged;

[0074] A control module 40 , electrically connected to the display screen 20 and the wireless charging module 30 , and configured to control the display screen 20 to display a charging area 201 ;

[0075] The charging area 201 is arranged corresponding to the wireless charging module 30 and is used to indicate the position where the device to be charged is placed on the display screen.

[0076] In the embodiment of the present disclosure, the charging device is used in the scenario of wirelessly charging the device to be charged. For example, the device to be charged is a wireless headset, and the charging device is a tablet computer. Figure 1b As shown, when the wireless headset A is low on power, by placing the wireless headset A in the charging area 201 displayed on the display screen 20 of the tablet computer B, the tablet computer B can provide the required power for the wireless headset A by transmitting a charging signal.

[0077] It should be noted that the volume of the device to be charged can be less than or equal to the volume of the charging device. In this way, the display screen can be used normally when displaying the charging area to realize wireless charging of the device to be charged, which can improve the user experience. For example, the device to be charged may include a Bluetooth headset or a sports watch. The charging device may be a mobile terminal device or a smart home device. The mobile terminal device may include a mobile phone, a tablet computer or a notebook; the smart home device may include a speaker device, etc., which is not limited in the embodiments of the present disclosure.

[0078] The housing has an opening, wherein the housing is used to protect the internal components of the charging device. The housing can be made of different materials, such as plastic, metal or composite materials, etc., which is not limited in the embodiments of the present disclosure. The size of the housing can vary according to the specific application and the type of charging device to ensure that the charging device has a beautiful appearance and meets the design requirements.

[0079] The display screen is installed at the opening of the housing, that is, the display screen includes a back side located in the housing and a front side opposite to the back side, and the front side of the display screen is used to present information to the user. That is, the display screen can display various information, such as time, date, device status, charging progress, etc.

[0080] The display screen may be a liquid crystal display (LCD), an organic light-emitting diode (OLED) or other suitable display technologies, which is not limited in the embodiments of the present disclosure.

[0081] It should be noted that the display screen and the housing enclose a storage space, which can accommodate other internal components, such as a battery module, a circuit board, and a camera. In addition, the display screen and the opening of the housing need to match each other, so that the display screen can be better installed at the opening of the housing. Here, the shape and size of the opening can be set according to the shape and size of the back of the display screen, and the embodiments of the present disclosure are not limited to this.

[0082] The wireless charging module is located in the accommodation space and is arranged on the back of the display screen, that is, the wireless charging module and the display screen are stacked to provide a charging signal to the device to be charged, so that the charging device can provide the required power for the device to be charged. The wireless charging module at least includes an antenna for transmitting signals. The wireless charging module can identify and establish a wireless charging connection with the device to be charged, and transmit a charging signal to the device, thereby charging the device to be charged.

[0083] The control module is located in a different position from the wireless charging module in the accommodation space, and is electrically connected to the display screen and the wireless charging module. The control module can control the display screen to display the charging area and the wireless charging module to output the charging signal by monitoring the status of the charging device and the device to be charged.

[0084] Illustratively, in one case, the control module can control the display screen to display the charging area when it detects that the device to be charged is ready to establish a communication connection with the charging device; in another case, the control module can also control the wireless charging module of the charging device to send a charging signal to the device to be charged in the charging area after detecting that the device to be charged is placed in the charging area of ​​the display screen, so that the charging device wirelessly charges the device to be charged.

[0085] In the disclosed embodiment, the control module controls the display screen to display the charging area, which may include: establishing a communication connection between the charging device and the device to be charged, obtaining device information associated with the device to be tested based on the communication connection, and controlling the display screen of the charging device to display the charging area when the device information meets the preset conditions. In this way, the display screen will display the charging area only when a charging demand is detected, which can not only make the charging device more intelligent and improve the user experience, but also save the power consumption of the charging device and extend the use time of the charging device.

[0086] It should be noted that when the wireless charging module is located at different positions on the back of the display screen, the charging area needs to be displayed on the display screen at the position corresponding to the wireless charging module. In other words, the wireless charging module can be set at any position on the back of the display screen, and the charging area can also be located at any position in the display area of ​​the display screen of the charging device. In this way, when the device to be tested is placed in the charging area, the charging device can better realize wireless charging for the device to be charged.

[0087] Exemplarily, when the wireless charging module is set in the middle position of the back of the display screen, the corresponding charging area is located in the middle position of the front of the display screen and is opposite to the position of the wireless charging module; or, when the wireless charging module is set at an edge position of the display screen other than the middle position, the corresponding charging area is located at an edge position of the front of the display screen other than the middle position and is opposite to the position of the wireless charging module.

[0088] In the embodiment of the present disclosure, the charging area is smaller than the display area of ​​the display screen. The charging area may include a display frame, and an icon or text indicating charging may be displayed in the display frame, and the present disclosure does not limit this. For example, a charging icon is displayed in the display frame.

[0089] In the embodiment of the present disclosure, a housing space is enclosed by the shell and the display screen, and a wireless charging module is arranged in the housing space. By arranging the wireless charging module on the back of the display screen, the device to be charged can be placed on the display screen for charging. In addition, the present disclosure arranges a control module to connect the display screen and the wireless charging module, and controls the display screen to display the charging area through the control module so that the display screen can indicate the position where the device to be charged is placed on the display screen. In this way, the present disclosure can not only solve the problem of inaccurate wireless charging alignment between the device to be charged and the charging device through the display area, and improve the charging alignment accuracy, but also allow the display screen to be used normally during wireless charging, thereby improving the user experience.

[0090] In one embodiment, Figure 2 is a schematic diagram of the structure of a charging device according to an exemplary embodiment. Figure 2 As shown, the wireless charging module 30 includes a flexible substrate 301 and a charging coil 302 formed on the flexible substrate 301;

[0091] The control module 40 is electrically connected to the charging coil 302 , and is configured to control the charging coil 302 to transmit the charging signal.

[0092] The flexible substrate is made of a soft and bendable material, such as a flexible printed circuit board (FPCB). The flexible printed circuit board may include a single-layer flexible printed circuit board, a multi-layer flexible printed circuit board, a rigid-flexible integrated printed circuit board, a foldable flexible printed circuit board, etc., which is not limited in the embodiments of the present disclosure.

[0093] The charging coil is a coil structure made of a conductive material, formed on a flexible substrate in a spiral or coiled form, and is used to generate and receive an electromagnetic field for wireless charging.

[0094] The shape and size of the charging coil can be set according to specific application requirements to adapt to different types of devices to be charged. For example, the charging coil can be circular, rectangular, triangular, etc., and the size of the charging coil can be greater than or equal to the contact area between the device to be charged and the charging device.

[0095] In the disclosed embodiment, the control module is electrically connected to the charging coil, and can control the charging coil to transmit a charging signal when the device to be charged is located in the charging area, wherein the charging signal includes an electromagnetic wave signal of a preset frequency generated after the charging coil is energized, and the device to be charged will generate an alternating current under the action of the electromagnetic wave signal to achieve wireless charging of the device to be charged; or, based on magnetic field resonance, when the charging device and the device to be charged are at the same frequency, they can exchange energy with each other to achieve wireless charging of the device to be charged.

[0096] It is understandable that, under the condition of the same current, the more turns the charging coil has and the denser the coils are, the greater the power of the transmitted charging signal.

[0097] In the embodiment of the present disclosure, a charging coil is provided to transmit a charging signal to the device to be charged, and the charging coil is provided on a flexible substrate, so that the flexibility of the wireless charging module can be increased, making it easier to place the wireless charging module in the accommodation space of the charging device.

[0098] In some embodiments, the charging coil comprises a near field communication (NFC) coil.

[0099] The charging coil includes a near field communication (NFC) coil. In some embodiments, the wireless charging module also includes an NFC chip connected to the NFC coil for processing near field communication information.

[0100] It is understandable that NFC communication usually operates at a frequency of 13.56 MHz, while high-frequency wireless charging usually uses high-frequency signals to transmit energy, with a frequency range greater than 1 MHz, that is, wireless charging based on NFC coils belongs to high-frequency wireless charging. Since high-frequency wireless charging has a shorter wavelength, it can reduce the physical size of the NFC coil, thereby reducing the volume of the wireless charging module in the accommodation space, making it more suitable for wireless charging of different devices to be charged.

[0101] In the disclosed embodiment, by using an NFC coil as the charging coil of the wireless charging module, not only can NFC communication be maintained, but also wireless charging can be performed for the device to be charged based on the charging coil, thereby reducing the space occupied by the wireless charging module in the charging device.

[0102] In some embodiments, Figure 2 As shown, the charging device also includes:

[0103] Battery module 50;

[0104] A driving circuit 60 electrically connected to the battery module 50 and the charging coil 302;

[0105] The control module 40 is electrically connected to the drive circuit 60 and the battery module 50 , and is further configured to control the drive circuit 60 to drive the charging coil 302 to transmit the charging signal having a sinusoidal waveform.

[0106] The above-mentioned battery module is located in the accommodating space of the charging device and may include one or more rechargeable batteries for storing electrical energy, being electrically connected to the devices in the charging device (for example, a drive circuit, a control module, a display screen or a wireless charging module), and providing electrical energy to the devices in the charging device.

[0107] The driving circuit is located in the accommodation space of the charging device and is electrically connected to the battery module and the charging coil, and is at least used to convert the electrical energy in the battery module into an electrical signal suitable for the charging coil.

[0108] The control module is electrically connected to the drive circuit and the battery module, that is, the battery module not only provides power to the drive circuit, but also provides power to the control module. The control module can be used to detect the state of the charging device and control the charging process. Based on the connection between the control module and the drive circuit, the frequency, power, waveform and other parameters of the charging coil can be adjusted by controlling the drive circuit, which is not limited in the embodiments of the present disclosure.

[0109] For example, Figure 3 is a schematic diagram of a driving circuit according to an exemplary embodiment. Figure 3As shown, the driving circuit 60 is connected to the battery module 50, and the battery module 50 is used to provide voltage for the driving circuit 60. The driving circuit 60 may include an inductor L1 and a transistor M1, which are used together to amplify the amplitude of the output signal; capacitors C1 and C2 are used to store charge; transistor M1 is connected to the charging coil 302 to form a single resistor and capacitor network, which can produce a maximum phase shift of 90 degrees for the amplified output signal to obtain good frequency stability and waveform, that is, the waveform of the charging signal output by the charging coil can be adjusted to be a sine wave.

[0110] It should be noted that when the waveform of the charging signal is a sine wave, the frequency and amplitude of the charging signal can be precisely adjusted to match the resonant frequency between the charging device and the device to be charged, which can maximize the energy transmission efficiency and reduce transmission losses. The sinusoidal wave signal is also stable and safe, and can reduce charging interruptions caused by electromagnetic interference.

[0111] In the disclosed embodiment, the control module controls the driving circuit to drive the charging coil to transmit a charging signal with a sinusoidal waveform, thereby reducing the display interference on the display screen of the charging device.

[0112] In some embodiments, when the display screen displays the charging area, the positive projection of the charging area onto the wireless charging module is located on the wireless charging module.

[0113] In the disclosed embodiment, the charging area is located on the front of the display screen, the wireless charging module is located on the back of the display screen, and the positive projection of the charging area onto the wireless charging module is located on the wireless charging module, that is, the charging area can be aligned with the wireless charging module.

[0114] It should be noted that the area of ​​the charging region can be smaller than or equal to the area of ​​the wireless charging module, so that when the device to be charged is located in the charging region, it can be opposite to the position of the wireless charging module.

[0115] In the disclosed embodiment, the positive projection of the charging area onto the wireless charging module is located on the wireless charging module. In this way, the wireless charging module and the device to be charged can be more accurately aligned and the charging efficiency can be higher.

[0116] In some embodiments, the wireless charging module is located at the intersection of two adjacent sides of the shell.

[0117] In the disclosed embodiment, the housing includes four sides, and the wireless charging module can be located at the angle between any two adjacent sides. For example, the wireless charging module can be located at the upper left corner, lower left corner, upper right corner or lower right corner of the back of the display screen.

[0118] It should be noted that when the wireless charging module is located at the intersection of two adjacent sides of the shell, the charging area is set at the intersection of two adjacent sides of the display screen and is opposite to the position of the wireless charging module, that is, the charging area is set at the edge of the display screen.

[0119] In this way, when the device to be charged is placed in the charging area, it is more convenient for users to view the display information of the display screen at the edge of the display screen than setting the charging area in the central area of ​​the display screen, which can improve the viewing effect of the display screen when the charging area is displayed.

[0120] In some embodiments, Figure 2 As shown, the charging device also includes:

[0121] A detection module 70 is disposed in the accommodating space at a distance from the wireless charging module 30 and is configured to detect the position of the device to be charged on the display screen 20;

[0122] The control module 40 is electrically connected to the detection module 70 , and is also configured to obtain the position of the device to be charged on the display screen 20 , and send the charging signal to the device to be charged when the device to be charged is located in the charging area 201 .

[0123] The above-mentioned detection module is connected to the display screen and is arranged in the accommodating space at a distance from the wireless charging module. For example, when the wireless charging module is located at a first angle where the first side and the second side of the shell are connected, the detection module can be located at a second angle in the shell adjacent to the first angle.

[0124] It should be noted that the detection module may include: infrared sensors, ultrasonic sensors or capacitive touch sensors, etc. For example, the charging device uses an infrared sensor to capture the position of the device to be charged and determine whether the device to be charged is located in the charging area; for another example, the charging device uses one or more ultrasonic sensors to emit ultrasonic signals and determine the distance of the device to be charged based on the reflected signals; for another example, the charging device can also use a capacitive touch sensor, which can not only detect the change in capacitance when the device to be charged touches or approaches the charging device to determine the position of the device to be charged, but also detect the duration and pressure of the contact between the device to be charged and the display screen.

[0125] The above-mentioned control module is electrically connected to the detection module, and is configured to obtain the position of the device to be charged on the display screen through the detection module, that is, to obtain whether the device to be charged is located in the charging area on the display screen or outside the charging area, and when obtaining the information that the device to be charged is located in the charging area, control the wireless charging module to send a charging signal to the device to be charged.

[0126] Here, the device to be charged is located in the charging area, which may include: the distance between the center of the device to be charged and the center of the charging area is less than the charging distance. The device to be charged is located outside the charging area, which may include: the distance between the center of the device to be charged and the center of the charging area is greater than or equal to the charging distance.

[0127] It should be noted that when the device to be charged is within the charging area, the charging device can better wirelessly charge the device to be charged. When the charging device is outside the charging area, the charging effect of the charging device is poor or the device to be charged cannot be wirelessly charged.

[0128] In the disclosed embodiment, the detection module detects the position of the device to be charged on the display screen. Based on the position of the device to be charged on the display screen, the control module controls the wireless charging module to send a charging signal to the device to be charged when the device to be charged is within the charging area. This can improve the efficiency of the charging device charging the device to be charged.

[0129] In some embodiments, the control module is further configured to output position offset information when the position of the device to be charged on the charging area changes and the amount of position change of the device to be charged is greater than a preset change threshold.

[0130] It should be noted that when the device to be charged is charged on the display screen, due to wireless charging, the position of the device to be charged may be offset, and the position offset may lead to low charging efficiency or disconnection of the charging connection.

[0131] Based on this, during the charging process, when the detection module detects that the position of the device to be charged is offset, the control module outputs position offset information based on the position change of the device to be charged.

[0132] Exemplarily, the detection module detects that the position of the device to be charged on the charging area is at a first position. When the device to be charged shifts, the detection module detects that the shifted position is at a second position. Based on the coordinates of the second position on the display screen and the coordinates of the first position on the display screen, the control module can obtain the position change between the second position and the first position, and determine whether the device to be charged is shifted outside the charging area through the position change.

[0133] It should be noted that when the position change is less than or equal to the change threshold, the device to be charged is at least partially located in the charging area; when the position change is greater than the preset change threshold, the device to be charged is located outside the charging area.

[0134] When the control module obtains that the position change is greater than a preset change threshold, the position offset information is output to the charging device. The position offset information may include an offset distance and an offset direction. The output form of the position offset information may include: voice output, text notification or vibration reminder, etc., which is not limited in this embodiment of the present disclosure.

[0135] In the disclosed embodiment, by outputting position offset information, the user can more quickly discover the position offset of the device to be charged and move the device to be charged to the charging area in time, thereby reducing the situation where the device to be charged does not receive the charging signal and improving the efficiency of the charging device charging the device to be charged.

[0136] In some embodiments, the control module is further configured as at least one of the following:

[0137] When the distance between the charging device and the device to be charged is less than a preset distance threshold, controlling the display screen to display the charging area;

[0138] When the current power of the device to be charged is less than a preset first power threshold, controlling the display screen to display the charging area;

[0139] When the movement speed of the device to be charged is greater than a preset speed threshold within a preset first time period and the movement direction of the device to be charged changes, the display screen is controlled to display the charging area.

[0140] The above charging device can obtain the distance between the charging device and the device to be charged through the distance measuring sensor in the charging device or the distance measuring sensor in the device to be charged. If the distance between the charging device and the device to be charged is less than the distance threshold, it indicates that the device to be charged needs to be charged, and the display screen is controlled to display the charging area; if the distance between the charging device and the device to be charged is greater than or equal to the distance threshold, it indicates that the device to be charged does not need to be charged, and the display screen does not need to be controlled to display the charging area.

[0141] The above charging device can obtain the current power of the device to be charged through the power meter in the device to be charged. If the current power of the device to be charged is less than the first power threshold, it indicates that the power of the device to be charged is insufficient and needs to be charged, and the display screen is controlled to display the charging area; if the current power of the device to be charged is greater than or equal to the first power threshold, it indicates that the device to be charged does not need to be charged, and the display screen does not need to be controlled to display the charging area.

[0142] The above-mentioned charging device can obtain the motion information of the device to be charged through the motion sensor in the device to be charged. During the preset first time period, the device to be charged has a motion speed greater than a preset speed threshold, and the motion direction of the device to be charged changes, that is, the device to be charged shakes rapidly, indicating that the power of the device to be charged is insufficient and needs to be charged. At this time, the control display screen displays the charging area. Here, the motion sensor includes: accelerometer and gyroscope, etc., which are not limited in the embodiments of the present disclosure.

[0143] Of course, in the embodiment of the present disclosure, the charging device can also receive a charging request sent by the device to be charged, and control the display screen to display the charging area based on the charging request. The charging request can be generated by the device to be charged in response to a user-specified operation. The specified operation includes single-clicking or double-clicking the device to be charged, which is not limited in the embodiment of the present disclosure.

[0144] It should be noted that the preset distance threshold, the preset first power threshold, the preset first time period, and the preset speed threshold can all be set according to actual requirements. For example, the preset distance threshold can be set within the range of 10 cm to 50 cm; the preset first power threshold can be set within the range of 15% to 60%; the preset first time period can be set within the range of 0.5 minutes to 5 minutes; the preset speed threshold can be set within the range of 3 cm per second to 10 cm per second, and the embodiments of the present disclosure are not limited to this.

[0145] In the disclosed embodiment, the control module is configured to control the display screen to display the charging area under different conditions, that is, when it is determined that the device to be charged needs to be charged, the display screen can promptly display the charging area. In this way, not only can the charging area be displayed intelligently, making the charging device more intelligent and improving the user experience, but it can also save the power consumption of the charging device and extend the use time of the charging device.

[0146] In some embodiments, the control module is further configured to stop sending the charging signal to the device to be charged if the current power of the device to be charged is greater than or equal to a preset second power threshold during the process of outputting the charging signal.

[0147] It should be noted that the process in which the control module controls the wireless charging module to output a charging signal includes: the device to be charged is located in the charging area of ​​the display screen, and the wireless charging module outputs a charging signal to the device to be charged.

[0148] In the embodiment of the present disclosure, the current power of the device to be charged is greater than or equal to a preset second power threshold, indicating that the current power of the device to be charged is in a fully charged state. At this time, the power of the device to be charged is sufficient and no further charging is required.

[0149] Here, the second power threshold is greater than the first power threshold. For example, the second power threshold can be set within a range of 80 percent to 100 percent.

[0150] It should be noted that in the process of outputting a charging signal to the device to be charged, the charging device can obtain the current power of the device to be charged in real time, and can judge whether the device to be charged does not need wireless charging at this time based on the comparison result of the current power of the device to be charged and the second power threshold. That is, the control module controls the wireless charging module to stop charging when the device to be charged is charged to a power level greater than or equal to the second power threshold. In this way, the situation in which the charging device continues to output a charging signal when the device to be charged reaches a fully charged state can be reduced, thereby reducing the loss of the charging device.

[0151] In some embodiments, the control module is further configured to control the display screen not to display the charging area after displaying the charging area if the device to be charged is outside the charging area within a preset second time period.

[0152] It should be noted that the display screen of the charging device displays the charging area, which means that the device to be charged is ready to be placed in the charging area for charging.

[0153] The device to be charged is located outside the charging area during the above-mentioned preset second time period, and the control module controls the display screen not to display the charging area, including: the control module obtains the position of the device to be charged on the display screen in real time during the second time period, and if the device to be charged is not in the charging area, the control module controls the display screen to turn off the display of the charging area.

[0154] The preset second time period may be set according to actual needs. For example, the preset second time period may be set within a range of 1 minute to 10 minutes.

[0155] In the embodiment of the present disclosure, if the control module does not obtain that the device to be charged is located in the charging area within a preset second time period, the control display screen will not display the charging area. That is, an upper limit on the waiting time is set before the device to be charged is placed in the charging area. This can reduce the situation where the charging device always displays the charging area, affecting the normal use of the charging device display screen, and can improve the user experience.

[0156] The present disclosure provides a charging method. Figure 4 is a flow chart of a charging method according to an exemplary embodiment. Figure 4 As shown, the method includes:

[0157] S101, obtaining device information associated with the device to be charged;

[0158] S102, when the device information meets a preset condition, controlling a display screen of the charging device to display a charging area;

[0159] S103: When it is detected that the device to be charged is located in the charging area, output a charging signal to the device to be charged.

[0160] In the disclosed embodiment, the charging method is applied to a scenario where a charging device provides wireless charging for a device to be charged. By executing the charging method, the charging device can improve the alignment accuracy between the charging device and the device to be charged, thereby improving the charging efficiency.

[0161] In step S101, before the charging device obtains the device information associated with the device to be charged, a communication connection is established with the device to be charged. Exemplarily, the communication connection can be established based on NFC communication, Bluetooth technology, WiFi direct connection technology, etc., which is not limited in the embodiments of the present disclosure.

[0162] In the disclosed embodiment, based on the communication connection between the charging device and the device to be charged, the device information associated with the device to be charged can be obtained, and the device information includes: device identification, battery status, device type, etc. It should be noted that the device information associated with the device to be charged can be continuously updated, so that the charging device can more accurately obtain whether the device to be charged needs to be charged based on the device information.

[0163] In step S102, when the device information meets the preset conditions, the display screen of the charging device is controlled to display the charging area, that is, it can be determined whether the device to be charged needs to be charged according to the device information.

[0164] For example, Figure 5 is a top view of a display screen of a charging device according to an exemplary embodiment. Figure 5 As shown, if the device information does not meet the preset conditions, it is considered that the device to be charged does not need to be charged, and the display screen 20 of the charging device does not display the charging area; Figure 6 is a top view of a display screen of a charging device according to an exemplary embodiment Figure 2 ,like Figure 6 As shown, if the device information meets the preset conditions, it is determined that the device to be charged needs to be charged, and the display screen 20 of the charging device displays the charging area 201.

[0165] In the disclosed embodiment, whether the display screen of the charging device displays the charging area can be determined by different preset conditions.

[0166] The above-mentioned preset conditions can be at least one set of rules or standards for determining whether the display screen needs to display the charging area. Exemplarily, the preset conditions can include checking whether the device to be charged supports wireless charging, whether the battery status requires charging, and whether the device to be charged is within the range of the wireless charging connection of the charging device, etc.

[0167] If the device information meets at least one of the above preset conditions, the charging device will further control the display screen to display the charging area. This step can be implemented by the control module to ensure that the display screen of the charging device can correctly display the charging area at the appropriate time.

[0168] In an embodiment of the present disclosure, based on obtaining device information associated with the device to be charged, when the device information meets preset conditions, the display screen of the charging device is controlled to display the charging area, so that the device to be charged can be placed on the display screen for charging; and, when the present disclosure detects that the device to be charged is located in the charging area, the present disclosure outputs a charging signal to the device to be charged. In this way, the present disclosure can not only solve the problem of inaccurate wireless charging alignment between the device to be charged and the charging device through the display area, and improve the charging alignment accuracy, but also can use the display screen normally during wireless charging, thereby improving the user experience.

[0169] In one embodiment, the device information includes: the distance between the charging device and the device to be charged, the current power of the device to be charged, and the movement information of the device to be charged;

[0170] The device information meets the preset condition including at least one of the following:

[0171] The distance between the charging device and the device to be charged is less than a preset distance threshold;

[0172] The current power of the device to be charged is less than a preset first power threshold;

[0173] During a preset first time period, the device to be charged has a movement speed greater than a preset speed threshold, and a movement direction of the device to be charged changes.

[0174] In the disclosed embodiment, the control module is configured to control the display screen to display the charging area under different conditions, that is, when it is determined that the device to be charged needs to be charged, the display screen can promptly display the charging area. In this way, not only can the charging area be displayed intelligently, making the charging device more intelligent and improving the user experience, but it can also save the power consumption of the charging device and extend the use time of the charging device.

[0175] In some embodiments, outputting a charging signal to the device to be charged includes:

[0176] Controlling the driving circuit of the charging device to send a driving signal to the charging coil of the charging device;

[0177] Based on the driving signal, the charging coil is controlled to transmit the charging signal having a sinusoidal waveform.

[0178] In the embodiment of the present disclosure, when it is detected that the device to be charged is located in the charging area, the control module of the charging device controls the drive circuit to start, and the drive circuit is used to generate and manage the charging signal, and is configured to send the drive signal to the charging coil in a controllable manner. That is, the drive circuit can amplify the amplitude of the input signal of the control circuit so that the output signal has sufficient power to drive the charging coil to transmit the charging signal. The drive circuit also includes a filter and a tuner to adjust the frequency and improve the signal quality.

[0179] In the disclosed embodiment, the driving circuit drives the charging coil to transmit a charging signal with a sinusoidal waveform, so that the transmission of the charging signal between the charging device and the device to be charged can be more stable, thereby reducing interference with the display screen.

[0180] In some embodiments, the method further comprises:

[0181] Detecting the position of the device to be charged on the display screen;

[0182] When it is detected that the position of the device to be charged on the charging area changes and the amount of change in the position of the device to be charged is greater than a preset change threshold, position offset information is output.

[0183] In the disclosed embodiment, the charging device can intelligently detect the position of the device to be charged on the display screen and issue a reminder when the position of the device to be charged shifts, which helps to ensure that the device to be charged is always located in the charging area during the charging process, thereby improving the efficiency and reliability of charging.

[0184] In some embodiments, the method further comprises:

[0185] During the process of outputting the charging signal, if the current power level of the device to be charged is greater than or equal to a preset second power level threshold, the charging signal is stopped from being sent to the device to be charged.

[0186] In the disclosed embodiment, by outputting position offset information, the user can more quickly discover the position offset of the device to be charged and move the device to be charged to the charging area in time, thereby reducing the situation where the device to be charged does not receive the charging signal and improving the efficiency of the charging device charging the device to be charged.

[0187] In some embodiments, the method further comprises:

[0188] After the charging area is displayed, if the device to be charged is located outside the charging area within a preset second time period, the display screen is controlled not to display the charging area.

[0189] It should be noted that the charging device can record the time after the charging area display starts, and within the preset second time period, the charging device continuously detects whether there is a device to be charged in the charging area.

[0190] In one case, the device to be charged has not been placed in the charging area. If the charging device is detected to be located in the charging area within a preset second time period, the charging device is controlled to send a charging signal to the device to be charged for charging; if the device to be charged is not detected to be located in the charging area within the preset second time period, the display screen is controlled to stop displaying the charging area.

[0191] In another case, during the charging process of the device to be charged in the charging area, if the charging device detects that the device to be charged has shifted to outside the charging area, the charging device starts timing. If the device to be charged is not detected to be moved into the charging area within a preset second time period, the control display screen stops displaying the charging area.

[0192] In the embodiment of the present disclosure, if the control module does not obtain that the device to be charged is located in the charging area within a preset second time period, the control display screen will not display the charging area. That is, an upper limit on the waiting time is set before the device to be charged is placed in the charging area. This can reduce the situation where the charging device always displays the charging area, affecting the normal use of the charging device display screen, and can improve the user experience.
