[0036] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] In related technologies, the magnetic cores of electronic devices and the magnetic cores of functional accessories often use cubic magnetic cores, and when charging, the two are arranged face to face, so that the magnetic flux linkage of the wireless charging magnetic field cannot form a loop, and most of the magnetic flux linkage diverges in other directions, resulting in a decrease in the coupling coefficient between the electronic device and the functional accessory, low efficiency during the wireless charging process, and a large amount of heat generation.

[0038] To solve the above technical problems, according to an embodiment of the present disclosure, an electronic device is provided. The electronic device is used in combination with an accessory device. The electronic device includes: a housing provided with a receiving groove for receiving the accessory device, and the accessory device is used in combination with the electronic device; a first wireless charging component disposed inside the housing and close to the receiving groove, and charging the accessory device through a first magnetic core. The arrangement of the first magnetic core satisfies the formation of a closed magnetic flux linkage in cooperation with the charging of the accessory device, and at least part of the first magnetic core is disposed in the receiving groove.

[0039] The present disclosure enhances the coupling of the wireless charging magnetic field by providing a receiving groove in the housing and enabling the magnetic flux linkage during the wireless charging process of the electronic device to form a closed loop instead of diverging, thereby enhancing the charging efficiency of the wireless charging, reducing the heat generation during charging, and improving the user experience.

[0040] It can be understood that the electronic device involved in the present disclosure can be a laptop computer, a desktop computer, a mobile phone, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, a translator, and wearable devices such as watches and bracelets, etc., and can be any electronic device with a wireless charging function. In the following description, a tablet computer is taken as an example for illustration, but the present disclosure is not limited thereto.

[0041] It can be understood that the terminal involved in the present disclosure, which can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device that provides voice and / or data connectivity to users. For example, the terminal can be a handheld device with wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminals are: mobile phone, pocket personal computer (PPC), palmtop computer, personal digital assistant (PDA), laptop computer, tablet computer, wearable device, or vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the specific technologies and specific device forms adopted by the terminal in the embodiments of the present disclosure are not limited.

[0042] It can be understood that the accessory device involved in the present disclosure can be any accessory device with a wireless charging function and can be used in combination with an electronic device. Exemplarily, the accessory device can be a stylus, headphones, a radiator, etc. In the following description, a stylus is taken as an example for illustration, but the present disclosure is not limited thereto.

[0043] Figure 1 It is a schematic structural diagram of an electronic device including a display accessory device, a wireless charging component, and a magnetic attraction member according to an exemplary embodiment. Figure 2 It is a schematic structural diagram of an accessory device according to an exemplary embodiment.

[0044] Figure 3 It is a schematic cross-sectional structural diagram of a first magnetic core and a second magnetic core according to an exemplary embodiment. Figure 4 It is another schematic cross-sectional structural diagram of a first magnetic core and a second magnetic core according to an exemplary embodiment.

[0045] In some embodiments, as Figures 1-4 shown, the electronic device can include a main body 10, and the main body 10 can include a housing 11. Exemplarily, the housing 11 can be the outer shell of the electronic device.

[0046] The housing 11 can be provided with a receiving groove 12, and the receiving groove can be used to receive the accessory device 60.

[0047] When the electronic device wirelessly charges the accessory device 60, the accessory device 60 can be placed in the receiving groove 12. By providing the receiving groove 12 on the housing 11, the part of the accessory device 60 protruding from the housing 11 during wireless charging can be reduced, thereby reducing the situation where the accessory device 60 falls due to accidental rubbing, and improving the connection stability during wireless charging of the accessory device 60.

[0048] The first wireless charging component 20 can be disposed inside the housing 20. Among them, the inside of the housing 20 can be the part for accommodating the electronic components of the electronic device surrounded by the housing 20.

[0049] The first wireless charging component 20 can include a first magnetic core 21 and a first coil 22. The first magnetic core 21 can be a magnetic conductive material component provided to increase the magnetic induction intensity of the first wireless charging component 20. A part of the first magnetic core 21 can be disposed in the receiving groove.

[0050] The first charging component 20 can include a charging mode. When the first wireless charging component 20 is in the charging mode, the first coil 22 can be energized, so that the first wireless charging component 20 generates an electromagnetic field for energy transmission.

[0051] The setting method of the first magnetic core 21 satisfies the charging cooperation with the second magnetic core of the second wireless charging component of the accessory device to form a closed magnetic chain, so that the magnetic chain can form a closed loop during wireless charging, enhancing the magnetic field coupling of wireless charging, thereby strengthening the charging efficiency of wireless charging, reducing heat generation during charging, and improving the user experience.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the accessory device 60 can include a second wireless charging component 30. The electronic device can charge the accessory device 60 through the first wireless charging component 20 and the second wireless charging component 30, so that the accessory device 60 can complete the charging process without additional charging devices, thereby reducing the supporting devices of the electronic device.

[0053] The accessory device 60 can be provided with a second wireless charging component 30, and the second wireless charging component 30 can include a second magnetic core 31 and a second coil 32. The second magnetic core 31 can be a magnetic conductive material component provided to increase the magnetic induction intensity of the second wireless charging component 30. When the second coil 32 is energized, the second wireless charging component 30 can generate an electromagnetic field for energy transmission.

[0054] In some embodiments, the accessory device 60 can be one or more of a stylus, headphones, or a radiator.

[0055] In some embodiments, such asFigure 4 As shown in the figure, the first magnetic core 21 can be provided with a groove 23, and the shape of the groove 23 can match the shape of the receiving groove 12, so that the first magnetic core 21 can be well matched and installed inside the housing 11 during the assembly of the electronic device.

[0056] In some embodiments, as Figures 1-4 shown, the first magnetic core 21 can include a first end 211 and a second end 212, and the first end 211 and the second end 212 can be disposed on opposite sides of the receiving groove. In the charging mode of the first wireless charging component 20, an electromagnetic field can be generated between the first end 211 and the second end 212.

[0057] When the accessory device 60 received in the receiving groove 12 cooperates with the first wireless charging component 20 for wireless charging, the accessory device 60 can be disposed between the first end 211 and the second end 212, so that the magnetic flux can form a closed loop during the wireless charging process, enhancing the magnetic field coupling of the wireless charging, thereby strengthening the charging efficiency of the wireless charging, reducing the heat generation during charging, and improving the user experience.

[0058] In some embodiments, as Figure 4 shown, the first end 211 and the second end 212 can form the opening of the groove 23, and the first end 211 and the second end 212 can be respectively disposed on both sides of the opening direction of the receiving groove 12. Exemplarily, the first end 211 and the second end 212 can be two opposite side walls of the groove 23. By providing the groove 23 on the first magnetic core 21 to generate the first end 211 and the second end 212, the production process of the first magnetic core 21 can be simplified, thereby reducing the production cost of the first wireless charging component 20.

[0059] In some embodiments, as Figure 3 and Figure 4 shown, the first magnetic core 21 can be an annular magnetic core or a rectangular ring magnetic core.

[0060] Wherein, the first magnetic core is an annular magnetic core or a rectangular ring magnetic core. By increasing the volume of the groove 23, the cross section of the first magnetic core 21 can be made annular, which can make the magnetic flux loop of the wireless charging component have a magnetic core while reducing the occupied space of the first magnetic core 21, thereby providing a larger installation space for the electronic device.

[0061] Wherein, in one example, the cross section of the first magnetic core 21 is one or a combination of C-shaped, rectangular, circular, and triangular. By changing the cross-sectional shape design of the first magnetic core 21, the first magnetic core 21 can be well matched and installed with the electronic device.

[0062] Exemplarily, when the cross-section of the first magnetic core 21 is C-shaped, the first magnetic core 21 can form a circular ring together with the second magnetic core 31 of the accessory device 60 during the charging process, so that the magnetic core exists on the loop of the magnetic flux of the wireless charging assembly, while reducing the occupied space of the first magnetic core 21, thereby providing a larger installation space for the electronic device.

[0063] Exemplarily, when the cross-section of the first magnetic core 21 is rectangular, the production process of the first magnetic core 21 can be simplified, thereby reducing the production cost of the first wireless charging assembly 20.

[0064] The first magnetic core 21 can be disposed inside the housing 11 and the distance from the receiving groove 12 is less than the first threshold distance. By reducing the distance between the first magnetic core 21 and the receiving groove 12, the distance between the first magnetic core 21 and the accessory device 60 placed in the receiving groove 12 can be reduced, which helps to increase the magnetic field strength during the wireless charging process, thereby enhancing the charging efficiency of the wireless charging, reducing the heat generation during the charging process, and improving the user experience.

[0065] And since the first magnetic core 21 has a first end 211 and a second end 212, and there is a gap between the first end 211 and the second end 212, the shape of the first magnetic core 21 can match the shape of the receiving groove 12, thereby improving the space utilization rate of the electronic device.

[0066] In some embodiments, the receiving groove 12 may have a receiving portion, and at least a part of the receiving portion may be located in the electromagnetic field between the first end 211 and the second end 212. Exemplarily, the receiving portion may be entirely located in the electromagnetic field between the first end 211 and the second end 212, so that during the wireless charging process, the second magnetic core 31 of the accessory device 60 can be entirely located in the electromagnetic field, enhancing the coupling of the wireless charging magnetic field, thereby enhancing the charging efficiency of the wireless charging, reducing the heat generation during the charging process, and improving the user experience.

[0067] In some embodiments, the receiving groove may be provided with a fixing member, and the accessory device received in the receiving groove is detachably connected to the receiving groove through the fixing member.

[0068] In some embodiments, the fixing member may include a first magnetic attracting member 41, and the first magnetic attracting member 41 can be used to magnetically attract and fix with the second magnetic attracting member 42 of the accessory device 60, and the accessory device 60 can be fixed to the receiving groove 12 through the first magnetic attracting member 41 and the second magnetic attracting member 42.

[0069] Through the magnetic attraction and fixation of the first magnetic member 41 and the second magnetic member 42, the accessory device 60 can be stably fixed within the receiving groove 12 during charging, reducing the accidental separation of the accessory device 60 from the electronic device due to the movement of the electronic device or the action of gravity, and improving the connection stability of the accessory device 60 during wireless charging.

[0070] In some embodiments, the first magnetic member 41 and the second magnetic member 42 can be matched with the shape of the receiving groove 12, so that the first magnetic member 41 and the second magnetic member 42 change from being opposite in a plane to being opposite in a curved surface under the same volume, increasing the relative area between the first magnetic member 41 and the second magnetic member 42, thereby enhancing the adsorption force between the first magnetic member 41 and the second magnetic member 42 and improving the connection stability of the accessory device 60 during wireless charging.

[0071] Figure 5 FIG. is a schematic structural diagram of an electronic device shown according to an exemplary embodiment. Figure 6 FIG. is a schematic structural diagram of an electronic device shown according to an exemplary embodiment.

[0072] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 shown, the receiving groove 12 can be provided with a fixing portion 50, and the fixing portion 50 can be used to fix the fixed end 61 of the accessory device 60, so as to make the connection structure between the accessory device 60 and the electronic device body 10 stable, and further enable the accessory device 60 to be used to support the body 10.

[0073] Exemplarily, the accessory device 60 can be a stylus, the stylus can include a touch end for touch control, and the fixed end 61 of the accessory device 60 can be the end opposite to the touch end in the length direction of the stylus.

[0074] By connecting the fixed end 61 of the accessory device 60 with the fixing portion 50 of the receiving groove 12, the stylus can be supported at one end against a plane such as a desktop and at the other end support the body 10 of the electronic device, so that the user does not need to carry an additional support bracket, which can increase the portability of the electronic device.

[0075] Exemplarily, the electronic device can be a tablet computer, and the accessory device 60 can provide support when the tablet computer is erected or when the tablet computer is placed horizontally.

[0076] In some embodiments, the electronic device can include a detection module, and the detection module can determine whether the electronic device is in a stand mode or a charging mode by detecting the signal value transmitted between the accessory devices 60.

[0077] Exemplarily, the detection module can detect the distance between the accessory device 60 and the electronic device. Depending on the different distances between the accessory device 60 and the electronic device, the electronic device can switch to the stand mode or the charging mode, enabling the electronic device to adapt to different usage scenarios.

[0078] In some embodiments, the quality factor Q value can be detected through the Foreign Object Debris (FOD) technology of the wireless charging protocol with the accessory device 60 to determine whether the electronic device is in the stand mode or the charging mode. By reusing the FOD technology for the mode detection of the electronic device, the additional components required for mode detection are reduced, thereby lowering the production cost of the electronic device.

[0079] In some embodiments, the electronic device can receive a second signal returned by the accessory device 60 according to the first signal. The first signal can be a signal sent by the electronic device at a fixed frequency. The electronic device can obtain the quality factor Q value based on the second signal and determine whether the electronic device is in the stand mode or the charging mode according to the Q value.

[0080] Exemplarily, the electronic device can transmit a pulse signal through the first wireless charging component 20 and receive a characteristic signal formed by the reflection of the pulse signal. Among them, the quality factor Q value at the end of the accessory device 60 and the quality factor Q value of the second wireless charging component of the accessory device 60 have different identification characteristics for the electronic device to distinguish.

[0081] When the electronic device detects that the quality factor Q value at the end of the accessory device 60 is greater than the first threshold, the electronic device switches to the charging mode and can charge the accessory device 60.

[0082] The electronic device can also detect the second distance between the fixing part 50 and the first end of the accessory device 60 through the characteristic signal. When the quality factor Q value of the second wireless charging component of the accessory device 60 is greater than the second threshold, the electronic device switches to the stand mode. At this time, the accessory device 60 can act as a stand to support the electronic device, enabling the electronic device to adapt to the requirements of different working scenarios.

[0083] In some embodiments, when the detection module detects that the quality factor Q value of the signal transmitted between the second wireless charging component 30 of the accessory device 60 and the first wireless charging component 20 is greater than the first threshold, it can be determined that the electronic device is in the charging mode, and the first wireless charging component charges the accessory device.

[0084] When the quality factor Q value of the signal transmitted between the resonant circuit provided at the end of the accessory device 60 and the electronic device detected by the detection module is greater than a second threshold, it can be determined that the electronic device is in the stand mode, and the accessory device supports the electronic device. By obtaining the quality factor Q value, the matching relationship between the electronic device and the stand of the accessory device 60 can be confirmed, so that the electronic device can be switched to the stand mode or the charging mode, enabling the electronic device to adapt to different usage scenarios.

[0085] In some embodiments, the detection module can detect the quality factor Q value through the FOD technology of the wireless charging protocol with the accessory device 60 to determine whether the electronic device is in the stand mode or the charging mode. By reusing the FOD technology for the mode detection of the electronic device, the additional components required for mode detection are reduced, and the production cost of the electronic device is lowered.

[0086] In some embodiments, the detection module can receive a second signal returned by the accessory device 60 according to a first signal, where the first signal can be a signal sent by the detection module at a fixed frequency, obtain the quality factor Q value according to the second signal, and determine whether the electronic device is in the stand mode or the charging mode according to the Q value.

[0087] Exemplarily, the detection module can transmit a pulse signal through the first wireless charging component 20 and receive a characteristic signal formed by the reflection of the pulse signal. Among them, the quality factor Q value at the end of the accessory device 60 and the quality factor Q value of the second wireless charging component of the accessory device 60 have different identification characteristics for the electronic device to distinguish.

[0088] The detection module can detect a first distance between the first wireless charging component 20 and the second wireless charging component 30 of the accessory device 60 through the characteristic signal. When the quality factor Q value at the end of the accessory device 60 is greater than a first threshold, it indicates that when the first distance is less than or equal to the first threshold distance, the electronic device switches to the charging mode, and the electronic device can charge the accessory device 60.

[0089] The detection module can also detect a second distance between the fixing part 50 and the first end of the accessory device 60 through the characteristic signal. When the quality factor Q value of the second wireless charging component of the accessory device 60 is greater than a second threshold, it indicates that when the second distance is less than or equal to the second threshold distance, the electronic device switches to the stand mode. At this time, the accessory device 60 can be used as a stand to support the electronic device, enabling the electronic device to adapt to different working scenario requirements.

[0090] In some embodiments, the first wireless charging component 20 can include a detection mode. The first wireless charging component 20 in the detection mode can transmit a pulse signal to detect the distance between the accessory device 60 and the receiving slot 12.

[0091] According to the distance between the accessory device 60 and the receiving groove 12, the working mode of the first wireless charging component 20 can be changed. Exemplarily, according to the distance between the accessory device 60 and the receiving groove 12, the first wireless charging component 20 can be changed to a charging mode or a detection mode.

[0092] According to the distance between the accessory device 60 and the receiving groove 12, the first wireless charging component 20 can also send a signal, and the electronic device can perform different operations according to the signal of the first wireless charging component 20.

[0093] In some embodiments, the fixing portion 50 can be a groove, and the fixing portion 50 and the fixed end 61 can be in an interference fit, which can make the connection between the fixing portion 50 and the fixed end 61 of the accessory device 60 simple and easy to operate.

[0094] The fixing portion 50 can be a buckle, and the fixing portion 50 and the fixed end 61 can be in a snap connection, which can make the connection between the fixing portion 50 and the fixed end 61 of the accessory device 60 stable.

[0095] The fixing portion 50 can be a screw hole, and the fixing portion 50 and the fixed end 61 can be in a threaded connection, which can make the connection between the fixing plate and the fixed end 61 of the accessory device 60 firm.

[0096] The present disclosure is not limited thereto, and the fixing portion 50 can also be changed to other fixing structures according to design requirements.

[0097] In some embodiments, a detection circuit can be provided at the fixed end 61 of the accessory device 60. The detection circuit can include one or more of a capacitor, a resistor, and an inductor.

[0098] After receiving the pulse signal emitted by the first wireless charging component 20, the first coil 22 can reflect a characteristic signal, so that the detection module can detect the quality factor of the first coil 22 to determine that the distance between the fixing portion 50 and the first wireless charging component 20 is less than or equal to the second threshold distance.

[0099] Exemplarily, when the distance between the fixing portion 50 and the first wireless charging component 20 is less than or equal to the second threshold distance, the pulse signal can detect the detection circuit located at the fixed end 61, which can make the quality factor detected by the detection module increase, thereby determining that the distance between the fixing portion 50 and the first wireless charging component 20 is less than or equal to the second threshold distance.

[0100] The first wireless charging component 20 in the detection mode emits a pulse signal and determines the distance between the fixed end 61 of the accessory device and the fixing portion by detecting the quality factor of the detection circuit provided at the fixed end 61 of the accessory device 60.

[0101] Among them, the quality factor, i.e., the Q value, is the main parameter for measuring an inductor component. It refers to the ratio of the inductive reactance presented by the inductor when operating under an AC voltage of a certain frequency to the equivalent loss resistance. The Q value of the first coil 22 is affected by the external environment. Exemplarily, when there is a metal foreign object in the receiving groove 12, it will cause the inductance of the first coil 22 to decrease and the equivalent impedance to increase, thereby resulting in a decrease in the Q value.

[0102] In some embodiments, the pulse signal can also be used to detect conductive foreign objects in the receiving groove. Exemplarily, when there is a metal foreign object in the receiving groove 12, it will cause the inductance of the first coil 22 to decrease and the equivalent impedance to increase, thereby resulting in a decrease in the Q value.

[0103] In some embodiments, the detection module may include a processor. The detection module of the electronic device may include a communication unit, and the communication unit may be configured to transmit signals to the processor.

[0104] When the detection circuit approaches the fixing portion 50, the Q value can be increased, so that the electronic device can determine the distance between the fixing portion 50 and the fixed end 61.

[0105] When the distance between the fixed end 61 and the fixing portion 50 is less than or equal to the first threshold distance, it represents that the fixed end 61 of the accessory device 60 is fixedly connected to the fixing portion 50.

[0107] In some embodiments, when the electronic device is in the stand mode and the display direction of the display interface of the electronic device is not the predetermined direction, the electronic device can prompt the user to convert the display direction of the display interface. And when the user issues a conversion instruction for the display direction of the interface according to the prompt operation, the electronic device can convert the display direction of the display interface to the predetermined direction, so that the electronic device can match the display interface with different mode states, facilitating the user to use and operate, and reducing the screen changes caused by misoperations.

[0108] In some other embodiments, when the electronic device is in the stand mode and the display direction of the display interface of the electronic device is not the predetermined direction, the electronic device can also directly adjust the display direction to the predetermined direction, so that the electronic device can match the display interface with different mode states, facilitating the user to use and operate the electronic device more conveniently.

[0109] In some other embodiments, when the electronic device is in the stand mode and the display direction of the display interface of the electronic device is not the predetermined direction, the electronic device may prompt the user to convert the display direction of the display interface. And when the electronic device does not receive a user's conversion instruction for the interface display direction within a preset duration, the electronic device may convert the interface display direction to the predetermined direction, so that the electronic device can match the display interface with different mode states, facilitating the user to use and operate the electronic device more conveniently.

[0110] Exemplarily, the predetermined direction may be a portrait display direction of the display screen.

[0111] Exemplarily, the electronic device may include a display screen, and the display direction of the display interface of the electronic device may be the screen display direction of the display screen.

[0112] In some embodiments, the electronic device may include a display screen. After receiving a connection signal, the display screen processor may convert the display screen to the target display direction and lock the screen display direction. The processor may also prompt the user through the display screen whether to rotate the screen to the target display direction or enter the working mode and other prompt information after receiving the signal, so as to facilitate the user to use the electronic device in this usage scenario, where the target display direction may include a portrait display direction or a landscape display direction.

[0113] When the distance between the fixed end 61 and the fixing part 50 of the accessory device 60 is greater than the first threshold distance, it represents that the fixed end 61 of the accessory device 60 is separated from the fixing part 50, and the accessory device 60 no longer provides the stand function for the electronic device. The communication unit may send a disconnection signal to the processor.

[0114] When the processor receives the disconnection signal sent by the communication unit, the processor may perform operations matching the usage scenario of not using the accessory device 60 for support, so as to facilitate the user to use the electronic device in this usage scenario.

[0115] Exemplarily, after receiving the disconnection signal, the processor may unlock the portrait mode and convert the screen to the landscape mode. The processor may also prompt the user whether to enter the landscape mode and other prompt information after receiving the signal, so as to facilitate the user to use the electronic device in this usage scenario.

[0116] Exemplarily, the fixing part 50 may be a groove. When the first wireless charging component 60 detects that the distance between the bottom of the groove and the fixed end 61 of the accessory device 60 is less than 1 centimeter, the electronic device may perform operations matching this usage scenario, so as to facilitate the user to use the electronic device in this usage scenario.

[0117] In some embodiments, when the processor receives a connection signal sent by the communication unit, the processor may control the electronic device to perform one or more of information prompting, rotating the screen, and locking the screen orientation, so as to facilitate the user to use the electronic device in this usage scenario.

[0118] When the processor receives a disconnection signal sent by the communication unit, the processor may control the electronic device to perform one or more of information prompting, rotating the screen, and unlocking the screen orientation, so as to facilitate the user to use the electronic device in this usage scenario.

[0119] In some embodiments, the first wireless charging component 20 in the detection mode may emit a pulse signal and determine the distance between the first wireless charging component 20 and the second wireless charging component 30 by detecting the quality factor of the second wireless charging component 30 of the accessory device 60.

[0120] When the distance between the first wireless charging component 20 and the second wireless charging component 30 is less than or equal to the second threshold distance, it represents that the accessory device 60 is accommodated in the accommodation groove 12, and the first wireless charging component 20 may change to the charging mode to charge the accessory device 60.

[0121] When the distance between the first wireless charging component 20 and the second wireless charging component 30 is greater than the second threshold distance, it represents that the accessory device 60 is not accommodated in the accommodation groove 12, and the first wireless charging component 20 may change to the detection mode to detect whether the accessory device 60 enters the accommodation groove 12.

[0122] Based on the same principle, the present disclosure also provides an accessory device.

[0125] The accessory device 60 may be provided with a second wireless charging component 30, and the second wireless charging component 30 may include a second magnetic core 31 and a second coil 32. The second magnetic core 31 may be a magnetic conductive material component provided to increase the magnetic induction intensity of the second wireless charging component 30. When the accessory device 60 is accommodated in the accommodation groove 12, the second magnetic core 31 and the first wireless charging component 20 cooperate for charging to form a closed magnetic chain. The magnetic chain during the wireless charging of the electronic device can form a closed loop instead of diverging, thereby enhancing the coupling of the wireless charging magnetic field, strengthening the charging efficiency of the wireless charging, reducing the heat generation during charging, and improving the user experience.

[0126] In some embodiments, the accessory device 60 may be shaped to match the accommodation groove 12 of the electronic device, so that the accessory device 60 can be accommodated in the accommodation groove 12.

[0127] In some embodiments, the accessory device 60 may also be shaped to match the first magnetic core 21, so that the second wireless charging component 30 of the accessory device 60 can better form a closed loop with the magnetic chain of the first wireless charging component, thereby improving the wireless charging efficiency.

[0128] In some embodiments, a fixed end 61 may be provided at the tail of the accessory device 60, and the fixed end 61 may be cooperatively provided with the fixing portion 50 of the accommodation groove 12 of the electronic device, so that the accessory device 60 can be fixedly connected to the electronic device through the cooperation between the fixed end 61 and the fixing portion 50, thereby enabling the accessory device 60 to support the electronic device as a bracket.

[0129] In some embodiments, the accessory device 60 can also be used to transmit signals to the electronic device, so that the detection module of the electronic device detects the signal value of the transmitted signal, determines the cooperation relationship between the electronic device and the accessory device 60, and thus can confirm that the electronic device is in the bracket mode or the charging mode, so that the electronic device can adapt to different usage scenarios.

[0132] In some embodiments, the signal feedback component can feedback signals to the electronic device. The electronic device and the accessory device 60 can detect the quality factor Q value through the foreign object detection (FOD) technology of the wireless charging protocol between the electronic device and the accessory device 60, so as to determine whether the electronic device is in the stand mode or the charging mode. By multiplexing the FOD technology for the mode detection of the electronic device, the additional components required for mode detection are reduced, and the production cost of the electronic device is lowered.

[0133] In some embodiments, the signal transmitting component can receive the first signal sent by the electronic device at a fixed frequency and feedback the second signal, and the second signal can be used to determine the quality factor Q value. The distance between the electronic device and the accessory device 60 can be determined through the quality factor Q value, so that the electronic device can be switched between the stand mode and the charging mode according to the cooperation state between the electronic device and the accessory device 60.

[0134] In some embodiments, the signal feedback component can be the second wireless charging component 30. When the quality factor Q value of the signal transmitted between the second wireless charging component 30 and the first wireless charging component 20 is greater than the first threshold, the cooperation relationship within the stand of the electronic device and the accessory device 60 can be confirmed, and the electronic device can be switched to the charging mode to charge the accessory device 60.

[0135] Exemplarily, when the quality factor Q value of the signal transmitted between the second wireless charging component 30 and the first wireless charging component 20 is greater than the first threshold, it means that the first distance between the first wireless charging component 20 and the second wireless charging component 30 of the accessory device 60 is less than the first threshold distance. The cooperation relationship within the stand of the electronic device and the accessory device 60 can be confirmed, and the electronic device can be switched to the charging mode to charge the accessory device 60.

[0136] In some embodiments, when the quality factor Q value of the signal transmitted between the resonant circuit at the tail of the accessory device 60 and the electronic device is greater than the second threshold, the cooperation state between the tail of the glimpse device 61 and the electronic device can be determined, so that it can be determined that the electronic device is in the stand mode to enable the accessory device to support the electronic device.

[0144] In some embodiments, the accessory device 60 can include a second magnetic attracting member 42, and the fixing member can include a first magnetic attracting member 41.

[0146] In some embodiments, the first magnetic attraction member 41 and the second magnetic attraction member 42 can be matched with the shape of the accommodation groove 12, so that the first magnetic attraction member 41 and the second magnetic attraction member 42 change from being opposite in a plane to being opposite in a curved surface under the same volume, increasing the relative area between the first magnetic attraction member 41 and the second magnetic attraction member 42, thereby enhancing the adsorption force between the first magnetic attraction member 41 and the second magnetic attraction member 42 and improving the connection stability during wireless charging of the accessory device 60.

[0147] In some embodiments, the accessory device 60 can be one or more of a stylus, headphones, or a radiator.
