[0036] The following is combined Figures 1-17 This application describes a charging device, a control method, a control apparatus, and a readable storage medium according to embodiments thereof.

[0037] like Figure 1 and Figure 2 As shown, according to some embodiments of this application, a charging device 100 is provided. The charging device 100 includes: a charging base 110; a magnetic attraction component 120 disposed on the charging base 110; and a controller 130 connected to the magnetic attraction component 120. The controller 130 is used to adjust the magnetic attraction strength and / or polarity of the magnetic attraction component 120 according to the status information of the external device 200.

[0038] In this embodiment, the present application defines a charging device 100, which includes a charging base 110 and a magnetic suction assembly 120. The charging base 110 is used to support an external device 200, and can also charge the external device 200. Specifically, a charging coil 122 can be provided in the charging base 110 to wirelessly charge the external device 200 through the charging coil 122.

[0039] The charging base 110 can be disc-shaped, with the external device 200 placed on top of the disc-shaped charging base 110. The charging base 110 can also be shaped like an inclined support, with the external device 200 leaning against it. In this embodiment, the specific shape of the charging base 110 is not strictly limited, as long as it meets the requirements of supporting the external device 200 and charging the external device 200.

[0040] In addition, the charging device 100 also includes a controller 130, which is connected to the magnetic attraction component 120 and is used to control the working state of the magnetic attraction component 120. Specifically, the controller 130 can acquire the status information of the external device 200, and the controller 130 can adjust the magnetic attraction strength and / or polarity of the magnetic attraction component 120 according to the acquired status information.

[0041] When the controller 130 determines from the status information that the likelihood of the user removing the external device 200 from the charging dock 110 is low, it controls the magnetic suction component 120 to provide a large magnetic force to ensure that the external device 200 can be fixed on the charging dock 110. This magnetic force helps resist external impacts such as vibration, ensuring charging efficiency. When the controller 130 determines from the status information that the likelihood of the user removing the external device 200 from the charging dock 110 is high, it controls the magnetic suction component 120 to reduce the magnetic force so that the magnetic force between the charging dock 110 and the external device 200 is insufficient to move the charging dock 110. The user can then lift the external device 200 to automatically separate the charging dock 110 and the external device 200. Alternatively, the controller 130 can adjust the magnetic poles of the magnetic suction component 120 so that it works in conjunction with the inherent magnetic poles of the external device 200 to apply a repulsive force to the external device 200, preventing the charging dock 110 from moving with the external device 200.

[0042] Therefore, this application solves the technical problems existing in the aforementioned related technologies by setting a controller 130 that can control the operation of the magnetic component 120 according to the working status of the external device 200. This allows the magnetic component 120 to automatically reduce the magnetic force or output a repulsive force when the user needs to remove the external device 200, thus preventing the external device 200 from dragging the charging base 110 and eliminating the need for the user to manually separate the charging base 110 and the external device 200. Furthermore, it optimizes the structure of the charging device 100 and improves its intelligence level.

[0043] Specifically, external devices 200 include wireless headphones, mobile phones, tablets, smartwatches, etc. Taking wireless headphones as an example, when a user removes the headphones 220, there is a high probability that the user will also remove the charging dock 110. The controller 130 then controls the magnetic component 120 to reduce the magnetic force on the charging case 210 based on this status information. Taking mobile phones as an example, when a user wakes up the phone screen through body movements or voice commands, there is a high probability that the user will remove the phone. The controller 130 then controls the magnetic component 120 to reduce the magnetic force on the phone based on this status information. This embodiment does not impose a hard limitation on the specific product type of external device 200, as long as it meets the requirement of controlling the operation of the magnetic component 120 based on status information.

[0044] According to some embodiments of this application, such as Figure 4 and Figure 5 As shown, the magnetic attraction assembly 120 includes: a coil 122 disposed in the charging base 110; and a power supply unit 124, one end of which is connected to the coil 122 and the other end of which is connected to the controller 130.

[0045] In this embodiment, the structure of the magnetic attraction component 120 is described. Specifically, the magnetic attraction component 120 includes a coil 122 and a power supply unit 124. The power supply unit 124 is a variable power source and is electrically connected to both ends of the coil 122. When the power supply unit 124 supplies power to the coil 122, the energized coil 122 generates an electromagnetic field, and the external device 200 is attracted to the charging base 110 under the action of this electromagnetic field. Furthermore, a controller 130 is connected to the power supply unit 124, and the controller 130 adjusts the magnetic attraction strength of the magnetic attraction component 120 by controlling the power supply unit 124.

[0046] Specifically, when the current flowing through the coil 122 is increased by controlling the power supply unit 124, the electromagnetic field strength generated by the coil 122 increases, i.e., the magnetic field density increases. This strengthens the attraction force of the magnetic component 120 on the external device 200, and the external device 200 is fixed to the charging base 110 under this strong magnetic attraction. When the current flowing through the coil 122 is decreased by controlling the power supply unit 124, the electromagnetic field strength generated by the coil 122 decreases, i.e., the magnetic field density decreases. This weakens the attraction force of the magnetic component 120 on the external device 200, allowing the user to automatically detach the charging base 110 by lifting the external device 200. Specifically, when a magnetic component 240 is installed inside the external device 200, the direction of the current flow in the coil 122 is controlled to generate an electromagnetic field with magnetic poles opposite to those of the magnetic component 240, ensuring that the electromagnetic field attracts the magnetic component 240. When the controller 130 determines from the status information that the user may remove the external device 200, it can also generate an electromagnetic field that repels the magnetic component 240 by outputting a reverse current to the coil 122, so as to automatically push the external device 200 away.

[0047] The magnetic component 120 has the advantages of low structural complexity and high reliability. The working state of the magnetic component 120 can be adjusted directly by changing the driving electrical parameters, thereby achieving the technical effect of charging device 100 at a low cost.

[0048] Specifically, coil 122 is a solenoid. Without changing the driving electrical parameters, the more turns the solenoid has, the stronger the magnetic field. Using a magnet in the solenoid will enhance the magnetic field.

[0049] Specifically, the magnetic attraction assembly 120 also includes a resistor 126, the first end of which is connected to the power supply unit 124, and the second end of which is connected to the coil 122. The resistor 126 is used for current limiting.

[0050] According to some embodiments of this application, such as Figure 3 As shown, the charging device 100 also includes: a first button 140, which is located on the charging base 110 and connected to the controller 130; when the first button 140 is triggered, the controller 130 controls the magnetic attraction component 120 to reduce the magnetic attraction strength.

[0051] In this embodiment, a first button 140 is provided on the charging dock 110, and the first button 140 is connected to the controller 130. When the user needs to remove the external device 200 from the charging dock 110, the user can send a first trigger signal to the controller 130 by triggering the first button 140. The controller 130 then controls the power supply unit 124 to reduce the current flowing into the coil 122 according to the first trigger signal, so as to reduce the magnetic attraction strength of the magnetic attraction component 120, so that the user can directly remove the external device 200 from the charging dock 110.

[0052] By setting the first button 140, a switch is formed on the charging device 100 that can be used to actively switch the working state of the magnetic component 120, so that the user can control the magnetic component 120 to reduce the magnetic attraction strength according to their own wishes, thereby providing convenient conditions for the user to take the external device 200.

[0053] According to some embodiments of this application, such as Figure 12 As shown, the charging device 100 also includes a communication component 150, which is connected to the controller 130 and is used to acquire status information.

[0054] In this embodiment, the charging device 100 is further provided with a communication component 150, which establishes communication with the external device 200 to obtain the status information of the external device 200, so as to realize the follow-up adjustment function of the magnetic suction component 120. The charging device 100 also includes a memory 170, and the controller 130 controls the operation of the magnetic suction component 120 according to the program stored in the memory 170.

[0055] Specifically, such as Figure 13 and Figure 14 As shown, taking wireless earphones as an example, the external device 200 includes a charging case 210 and earphones 220. The charging device 100 obtains power from the charging power supply 160 and charges the charging case power supply 2104 on the charging case 210 through the first charging component 180. The communication component 150 on the charging device 100 establishes a Bluetooth connection with the first Bluetooth component 2208 on the earphones 220 and / or the second Bluetooth component 2108 on the charging case 210, thereby obtaining the status information of the charging case 210 and the earphones 220.

[0056] The earphone 220 also includes an earphone power supply 2204, a first sensor 2206, and a speaker 2209. The first sensor 2206 is used to sense the wearing status of the earphone 220. The earphone control circuit 2202 generates corresponding status information based on the wearing status, so that the controller 130 can adjust the working status of the magnetic component 120 according to the wearing status of the earphone 220. The speaker 2209 is used to output audio information.

[0057] The earphone case 220 also includes a second charging component 2106, a second sensor 2109, and a second button 230. The second charging component 2106 charges the earphone power supply 2204. The second sensor 2109 senses the state of the charging case 210. For example, when a user grasps the outer surface of the charging case 210, the second sensor 2109 sends a signal to the charging case control circuit 2102. The charging case control circuit 2102 then sends corresponding status information to the controller 130 via the second Bluetooth component 2108, causing the controller 130 to reduce the magnetic attraction strength of the magnetic component 120 based on this status information. The second button 230 outputs a control command to actively reduce the magnetic attraction strength. The user can send a second trigger signal to the controller 130 by touching the second button 230. The controller 130 can then reduce the magnetic attraction strength of the magnetic component 120 based on the second trigger signal, thus providing convenience for the user to remove the earphone case 220.

[0058] According to some embodiments of this application, such as Figure 15 As shown, a control method is provided for controlling the charging device 100 as described in any of the above embodiments. The charging device 100 is used to charge an external device 200. The control method includes:

[0059] Step 1502: Obtain the status information of the external device;

[0060] Step 1504: Adjust the magnetic attraction strength and / or polarity of the magnetic attraction component according to the status information.

[0061] In this embodiment, the control method first acquires the status information of the external device, and then adjusts the working state of the magnetic attraction component according to the acquired status information to change the magnetic field strength and magnetic pole direction generated by the magnetic attraction component.

[0062] Specifically, when the status information indicates a low probability that the user will remove the external device from the charging dock, the magnetic component is controlled to provide a strong magnetic force to ensure the external device is securely attached to the charging dock. This magnetic force helps resist external impacts such as vibration, ensuring charging efficiency. When the status information indicates a high probability that the user will remove the external device from the charging dock, the magnetic component is controlled to reduce the magnetic force. This reduces the magnetic force between the charging dock and the external device to prevent the charging dock from moving. The user can then lift the external device to automatically separate them. Alternatively, the magnetic component can be adjusted to apply a repulsive force to the external device, aligning with the device's inherent magnetic poles, to prevent the charging dock from moving with the external device.

[0063] Therefore, this application, by defining the aforementioned control method, enables the magnetic component to automatically reduce its magnetic force when the user needs to remove the external device, thereby preventing the external device from dragging the charging dock and eliminating the need for the user to manually separate the charging dock and the external device. This solves the technical problems existing in the aforementioned related technologies. Furthermore, it achieves the technical effect of optimizing the charging device structure and improving the intelligence level of the charging device.

[0064] According to some embodiments of this application, such as Figure 9 and Figure 10 As shown, the status information includes the power information of the external device 200, which corresponds to the remaining power of the external device 200. The step of adjusting the magnetic attraction strength of the magnetic component based on the status information includes:

[0065] When the battery level of the external device is less than the preset battery level, the magnetic attraction strength of the magnetic component is adjusted to the first strength; when the battery level of the external device is greater than or equal to the preset battery level, the magnetic attraction strength of the magnetic component is adjusted to the second strength; wherein, the first strength is greater than the second strength.

[0066] In this embodiment, taking wireless earphones as an example, the external device 200 includes a charging case 210 and earphones 220. The charging case 210 is used to house the earphones 220 and can charge the earphones 220 placed inside. Based on this, a first method for determining the switching between strong and weak magnetic field working modes is proposed. Specifically, the status information includes the charging case's battery level. When it is determined that the charging case's battery level is less than a preset level, it indicates that the charging case is not fully charged and there is still a need to charge it using the charging dock. To address this, the magnetic attraction strength of the magnetic component is adjusted to a first strength to firmly hold the charging case in place by a strong magnetic field before it is fully charged, preventing the charging case from falling off. When it is determined that the charging case's battery level is greater than or equal to a preset level, it indicates that the charging case is fully charged and there is currently no need to charge it. To address this, the magnetic attraction strength of the magnetic component is adjusted to a second strength to ensure that the user will not drag the charging dock away when removing the charging case later.

[0067] The external device can also be a mobile phone, and the control method can adjust the magnetic strength of the magnetic component according to the phone's battery level. This embodiment does not impose any hard limitations on the specific type of external device.

[0068] Specifically, such as Figure 6 As shown, when the probability of the current user taking away the external device is low based on the status information, the power supply output voltage V1 is controlled, the current generated in the coil is I1, and the magnetic field strength generated by the coil is the first strength B1.

[0069] like Figure 7 As shown, the output voltage of the control power supply is V2, the current generated in the coil is I2, and the magnetic field strength generated by the coil is the first strength B2, where V1 is greater than V2, I1 is greater than I2, and B1 is greater than B2.

[0070] By controlling the magnetic strength of the magnetic component to switch between a first strength and a second strength, the component can operate in both a strong magnetic field mode and a weak magnetic field mode. The strong magnetic field mode enhances the attraction to external devices, reducing the likelihood of misalignment or detachment, thus improving charging stability. The weak magnetic field mode reduces the attraction to external devices when the user might remove them, preventing the device from dragging the charging dock along with it, thus providing greater convenience for the user.

[0071] According to some embodiments of this application, such as Figure 9 and Figure 10 As shown, the external device is a charging case 210, which is equipped with corresponding earphones 220. The charging case 210 is used to hold the earphones 220 and charge them. The status information also includes wearing action information and removing action information of the earphones 220. The wearing action information is determined by the earphones 220 based on the user's wearing action, and the removing action information is determined by the earphones 220 based on the user's removing action. The step of adjusting the magnetic attraction strength of the magnetic component according to the status information includes:

[0072] When wearing action information is obtained, the magnetic attraction strength of the magnetic component is adjusted to a first strength; when removing action information is obtained, the magnetic attraction strength of the magnetic component is adjusted to a second strength; wherein, the first strength is greater than the second strength.

[0073] In this embodiment, a second method for determining the switching between strong and weak magnetic field operating modes is proposed. Specifically, the status information also includes the wearing status of the earphones. When the status information determines that the earphones are currently being worn, it indicates that the user is using the earphones and the probability of removing the charging case is relatively low. The magnetic component is then controlled to adjust the magnetic attraction strength to the first strength, using a strong magnetic field to enhance the fixation effect on the charging case, thereby improving charging stability and efficiency. Conversely, when the status information determines that the earphones are currently not being worn, it indicates that the user has removed the earphones and the probability of removing the charging case and placing the earphones back into it is relatively high. The magnetic component is then controlled to adjust the magnetic attraction strength to the second strength, using a weak magnetic field to reduce the attraction force on the charging case, preventing the user from dragging the charging dock when removing the charging case, thus improving the user experience and eliminating the need to manually separate the charging dock and charging case.

[0074] Specifically, such as Figure 6 As shown, when the probability of the current user taking away the external device is low based on the status information, the power supply output voltage V1 is controlled, the current generated in the coil is I1, and the magnetic field strength generated by the coil is the first strength B1.

[0075] like Figure 7 As shown, the output voltage of the control power supply is V2, the current generated in the coil is I2, and the magnetic field strength generated by the coil is the first strength B2, where V1 is greater than V2, I1 is greater than I2, and B1 is greater than B2.

[0076] By controlling the magnetic strength of the magnetic component to switch between a first strength and a second strength, the component can operate in both a strong magnetic field mode and a weak magnetic field mode. The strong magnetic field mode enhances the attraction to external devices, reducing the likelihood of misalignment or detachment, thus improving charging stability. The weak magnetic field mode reduces the attraction to external devices when the user might remove them, preventing the device from dragging the charging dock along with it, thus providing greater convenience for the user.

[0077] According to some embodiments of this application, such as Figure 10 and Figure 11 As shown, the status information also includes charging stop information. The external device 200 generates charging stop information based on the user's input command and adjusts the magnetic strength and / or polarity of the magnetic component according to the status information, specifically including:

[0078] Upon receiving a stop charging information, the magnetic attraction strength of the magnetic attraction component is adjusted to the second strength, and / or the polarity of the magnetic attraction component is reversed.

[0079] In this embodiment, the status information also includes charging stop information. Receiving charging stop information indicates that the current charging operation of the external device is about to end, and the user is about to remove the external device from the charging dock. Specifically, the charging stop information is generated based on a command input by the user on the external device. For example, it can be generated by touching a button on the external device, recording a touch command on the external device's touchscreen, or generating the charging stop information via voice command. This embodiment does not impose a rigid limitation on the specific method of generating the charging stop information.

[0080] Upon receiving the information that charging has stopped, the magnetic attraction component is controlled to reduce its magnetic attraction strength to a second strength and / or reverse its polarity. Reducing the magnetic attraction strength can decrease the magnetic attraction force of the magnetic attraction component on the external device to prevent the charging dock from being dragged by the external device. Reversing the polarity can output a repulsive force to the external device to separate the external device from the charging dock.

[0081] Specifically, the external device also includes a second button, which is located on the charging case and / or earphones. The user can send a stop charging message to the controller by touching the second button. After receiving the stop charging message, the controller adjusts the magnetic attraction strength to the second strength and / or reverses the polarity of the magnetic attraction component.

[0082] Specifically, such as Figure 6 As shown, the output voltage V1 of the control power supply unit generates a current I1 in the coil, and the magnetic field strength generated by the coil is a first strength B1. If the external device contains a magnet, and the S pole of the magnet faces the charging base, the current in the control coil is transmitted along the first flow direction, thereby forming an electromagnetic field with the N pole above and the S pole below, to ensure that the external device can be attracted to the charging base.

[0083] Specifically, such as Figure 7 As shown, the control power supply output voltage V2 generates a current I2 in the coil, and the magnetic field strength generated by the coil is a first strength B2, where V1 is greater than V2, I1 is greater than I2, and B1 is greater than B2. If the external device contains a magnet, and the magnet's S pole faces the charging base, the current in the control coil flows along the first direction, thereby forming an electromagnetic field with the N pole above and the S pole below. Based on this, the magnetic attraction force is reduced by the aforementioned method of reducing magnetic attraction strength, so that the external device and the charging base automatically separate. Or, as... Figure 8 As shown, the current in the control coil flows along the second direction, thereby forming an electromagnetic field with the upper S pole and the lower N pole, causing external devices to repel each other. According to some embodiments of this application, such as... Figure 16As shown, a control device 1600 is proposed. The control device 1600 is used to control the charging device as described in any of the above embodiments. The charging device is used to charge an external device. The control device 1600 includes: an acquisition module 1602 for acquiring the status information of the external device; and an adjustment module 1604 for adjusting the magnetic attraction strength and / or magnetism of the magnetic attraction component according to the status information.

[0084] In this embodiment, the acquisition module 1602 is used to acquire the status information of the external device, and the adjustment module 1604 is used to adjust the working state of the magnetic attraction component according to the acquired status information, so as to change the magnetic field strength and magnetic pole direction generated by the magnetic attraction component.

[0085] Specifically, when the status information indicates a low probability that the user will remove the external device from the charging dock, the adjustment module 1604 controls the magnetic component to provide a large magnetic force to ensure the external device is fixed to the charging dock. This magnetic force helps resist external impacts such as vibration, ensuring charging efficiency. When the status information indicates a high probability that the user will remove the external device from the charging dock, the adjustment module 1604 correspondingly controls the magnetic component to reduce the magnetic force. This reduces the magnetic force between the charging dock and the external device to be insufficient to cause the charging dock to move. The user can then lift the external device to automatically separate them. Alternatively, the adjustment module 1604 can adjust the magnetic poles of the magnetic component to apply a repulsive force to the external device, preventing the charging dock from moving with it.

[0086] Therefore, this application, by defining the aforementioned control device 1600, enables the magnetic component to automatically reduce its magnetic force when the user needs to remove the external device, thereby preventing the external device from dragging the charging dock and eliminating the need for the user to manually separate the charging dock and the external device. This solves the technical problems existing in the aforementioned related technologies. Furthermore, it achieves the technical effect of optimizing the charging device structure and improving the intelligence level of the charging device.

[0087] According to some embodiments of this application, such as Figure 9 and Figure 10 As shown, the status information includes the power information of the external device 200, which corresponds to the remaining power of the external device 200. The adjustment module 1604 is also used to: adjust the magnetic attraction strength of the magnetic component to a first strength when the power of the external device is less than the preset power; and adjust the magnetic attraction strength of the magnetic component to a second strength when the power of the external device is greater than or equal to the preset power; wherein the first strength is greater than the second strength.

[0088] In this embodiment, taking wireless earphones as an example, the external device includes a charging case and earphones. The charging case is used to hold the earphones and can charge the earphones placed inside. Based on this, a first adjustment module 1604 is proposed. Specifically, the status information includes the charging case's battery level. When it is determined that the charging case's battery level is less than a preset level, it indicates that the charging case is not fully charged and there is still a need to charge it using the charging dock. To address this, the magnetic attraction strength of the magnetic component is adjusted to a first strength to firmly hold the charging case in place using a strong magnetic field before it is fully charged, preventing it from falling off. When it is determined that the charging case's battery level is greater than or equal to the preset level, it indicates that the charging case is fully charged and there is currently no need to charge it. To address this, the magnetic attraction strength of the magnetic component is adjusted to a second strength to ensure that the user will not drag the charging dock away when removing the charging case later.

[0089] The external device can also be a mobile phone, and the control method can adjust the magnetic strength of the magnetic component according to the phone's battery level. This embodiment does not impose any hard limitations on the specific type of external device.

[0090] Specifically, such as Figure 6 As shown, when the probability of the current user taking away the external device is low based on the status information, the power supply output voltage V1 is controlled, the current generated in the coil is I1, and the magnetic field strength generated by the coil is the first strength B1.

[0091] like Figure 7 As shown, the output voltage of the control power supply is V2, the current generated in the coil is I2, and the magnetic field strength generated by the coil is the first strength B2, where V1 is greater than V2, I1 is greater than I2, and B1 is greater than B2.

[0092] By controlling the magnetic strength of the magnetic component to switch between a first strength and a second strength, the component can operate in both a strong magnetic field mode and a weak magnetic field mode. The strong magnetic field mode enhances the attraction to external devices, reducing the likelihood of misalignment or detachment, thus improving charging stability. The weak magnetic field mode reduces the attraction to external devices when the user might remove them, preventing the device from dragging the charging dock along with it, thus providing greater convenience for the user.

[0093] According to some embodiments of this application, such as Figure 9 and Figure 10As shown, the external device is a charging case 210, which is equipped with corresponding earphones 220. The charging case 210 is used to hold the earphones 220 and charge them. The status information also includes wearing action information and removing action information of the earphones 220. The wearing action information is determined by the earphones 220 based on the user's wearing action, and the removing action information is determined by the earphones 220 based on the user's removing action. The adjustment module 1604 is also used to: adjust the magnetic attraction strength of the magnetic component to a first strength when the wearing action information is obtained; and adjust the magnetic attraction strength of the magnetic component to a second strength when the removing action information is obtained; wherein the first strength is greater than the second strength.

[0094] In this embodiment, a second mode of operation for the adjustment component is proposed. Specifically, the status information also includes the wearing status of the earphones. When the status information determines that the earphones are currently being worn, it indicates that the user is using the earphones and the probability of removing the charging case is relatively low. The magnetic component is then controlled to adjust the magnetic strength to a first strength to enhance the fixation effect on the charging case through a strong magnetic field, thereby improving charging stability and efficiency. Conversely, when the status information determines that the earphones are currently not being worn, it indicates that the user has removed the earphones and the probability of removing the charging case and placing the earphones back into it is relatively high. The magnetic component is then controlled to adjust the magnetic strength to a second strength to reduce the attraction force on the charging case through a weak magnetic field, preventing the user from dragging the charging dock when removing the charging case, thus improving the user experience and eliminating the need to manually separate the charging dock and charging case.

[0095] Specifically, such as Figure 6 As shown, when the probability of the current user taking away the external device is low based on the status information, the power supply output voltage V1 is controlled, the current generated in the coil is I1, and the magnetic field strength generated by the coil is the first strength B1.

[0096] like Figure 7 As shown, the output voltage of the control power supply is V2, the current generated in the coil is I2, and the magnetic field strength generated by the coil is the first strength B2, where V1 is greater than V2, I1 is greater than I2, and B1 is greater than B2.

[0097] By controlling the magnetic strength of the magnetic component to switch between a first strength and a second strength, the component can operate in both a strong magnetic field mode and a weak magnetic field mode. The strong magnetic field mode enhances the attraction to external devices, reducing the likelihood of misalignment or detachment, thus improving charging stability. The weak magnetic field mode reduces the attraction to external devices when the user might remove them, preventing the device from dragging the charging dock along with it, thus providing greater convenience for the user.

[0098] According to some embodiments of this application, such as Figure 10 and Figure 11 As shown, the status information also includes charging stop information. The external device 200 generates charging stop information according to the user input command. The adjustment module 1604 is also used to: adjust the magnetic attraction strength of the magnetic attraction component to the second strength when the charging stop information is obtained, and / or reverse the polarity of the magnetic attraction component.

[0099] In this embodiment, the status information also includes charging stop information. Receiving charging stop information indicates that the current charging operation of the external device is about to end, and the user is about to remove the external device from the charging dock. Specifically, the charging stop information is generated based on a command input by the user on the external device. For example, it can be generated by touching a button on the external device, recording a touch command on the external device's touchscreen, or generating the charging stop information via voice command. This embodiment does not impose a rigid limitation on the specific method of generating the charging stop information.

[0100] Upon receiving the information that charging has stopped, the magnetic attraction component is controlled to reduce its magnetic attraction strength to a second strength and / or reverse its polarity. Reducing the magnetic attraction strength can decrease the magnetic attraction force of the magnetic attraction component on the external device to prevent the charging dock from being dragged by the external device. Reversing the polarity can output a repulsive force to the external device to separate the external device from the charging dock.

[0101] Specifically, the external device also includes a second button, which is located on the charging case and / or earphones. The user can send a stop charging message to the controller by touching the second button. After the acquisition module 1602 receives the stop charging message, the adjustment module 1604 controls the magnetic attraction component to adjust the magnetic attraction strength to the second strength and / or reverse the polarity of the magnetic attraction component.

[0102] Specifically, such as Figure 6 As shown, the output voltage V1 of the control power supply unit generates a current I1 in the coil, and the magnetic field strength generated by the coil is a first strength B1. If the external device contains a magnet, and the S pole of the magnet faces the charging base, the current in the control coil is transmitted along the first flow direction, thereby forming an electromagnetic field with the N pole above and the S pole below, to ensure that the external device can be attracted to the charging base.

[0103] Specifically, such as Figure 7 As shown, the control power supply output voltage V2 generates a current I2 in the coil, and the magnetic field strength generated by the coil is a first strength B2, where V1 is greater than V2, I1 is greater than I2, and B1 is greater than B2. If the external device contains a magnet, and the magnet's S pole faces the charging base, the current in the control coil flows along the first direction, thereby forming an electromagnetic field with the N pole above and the S pole below. Based on this, the magnetic attraction force is reduced by the aforementioned method of reducing magnetic attraction strength, so that the external device and the charging base automatically separate. Or, as... Figure 8 As shown, the current in the control coil is transmitted along the second direction, thereby forming an electromagnetic field with the upper S pole and the lower N pole, so that the external devices are repelled and bounced away.
