[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be fully described below with reference to the accompanying drawings in the embodiments of this invention, through specific implementation methods. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort fall within the protection scope of this invention.

[0019] Figure 1 This is a schematic diagram of a dual-charging mode control system provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of another dual-charging mode control system provided in an embodiment of the present invention, referred to... Figure 1 and Figure 2 As shown, the dual-charging-mode control system 10 includes a charging cable module 400, a mode switching module 300, a wireless charging control module 200, and a power supply module 100. The power supply module 100 is electrically connected to the wireless charging control module 200. The charging cable module 400 includes an inner charging cable end 420 and an outer charging cable end 430. The mode switching module 300 includes a charging cable interface 310, a mode switching interface 320, a potential signal output terminal 330, a wired power supply interface 340, and a wireless power supply interface 350. The wireless charging control module 200 includes a potential signal acquisition terminal 210, a charging cable control terminal 220, and a wireless power supply terminal 230. The power supply module 100 includes a wired charging power supply terminal 110. The charging cable interface 310 is electrically connected to the inner charging cable end 420, and the potential signal output terminal 330 is electrically connected to the potential signal acquisition terminal 210. The wired power supply interface 340 is electrically connected to the wired charging power supply terminal 110, and the wireless power supply interface 350 is electrically connected to the wireless power supply terminal 230. The wireless charging control module 200 is used to control the control system 10 to operate in a first working mode or a second working mode according to the potential signal received by the potential signal acquisition terminal 210. In the first working mode, the charging cable outer end 430 is electrically connected to the device to be charged 20, and the charging cable control terminal 220 controls the charging cable interface 310 to be electrically connected to the wired power supply interface 340. The control system 10 is used to perform wired charging on the device to be charged 20. In the second working mode, the charging cable outer end 430 is electrically connected to the mode switching interface 320, and the charging cable control terminal 220 controls the charging cable interface 310 to be electrically connected to the wireless power supply interface 350. The control system 10 is used to perform wireless charging on the device to be charged 20.

[0020] The dual-charging mode control system 10 includes two operating modes: a first operating mode and a second operating mode. These two operating modes ensure the diverse functions of the dual-charging mode control system 10, providing convenience for daily life. Specifically, the dual-charging mode control system 10 includes a charging cable module 400, a mode switching module 300, a wireless charging control module 200, and a power supply module 100. Based on the connection status of the charging cable module 400, the wireless charging control module 200 collects different potential signals and controls the different connection statuses of the internal ports of the mode switching module 300 according to the potential signals, thereby controlling the control system 10 to operate in either the first or second operating mode. The first operating mode refers to wired charging of the device 20 to be charged, and the second operating mode refers to wireless charging of the device 20 to be charged. For example, the device 20 to be charged can be a mobile phone, computer, or tablet computer, etc., and this embodiment of the invention does not impose specific limitations.

[0021] Furthermore, the charging cable module 400 includes a charging cable body 410, an inner charging cable end 420, and an outer charging cable end 430. The inner charging cable end 420 and the outer charging cable end 430 are located within the charging cable module 400 and are electrically connected through the charging cable body 410. The charging cable body 410 includes a positive charging cable and a negative charging cable to ensure power transmission. The mode switching module 300 includes a charging cable interface 310, which is electrically connected to the inner charging cable end 420. That is, the mode switching module 300 is electrically connected to the charging cable module 400. By changing the electrical connection method of the ports included in the mode switching module 300 and combining it with the state presented by the charging cable module 400, wired charging or wireless charging can be achieved.

[0022] Furthermore, the mode switching module 300 also includes a mode switching interface 320 and a potential signal output terminal 330, and the wireless charging control module 200 includes a potential signal acquisition terminal 210, wherein the potential signal output terminal 330 is electrically connected to the potential signal acquisition terminal 210. For example, see reference... Figure 1 As shown, when the charging cable's outer end 430 is electrically connected to the device to be charged 20, i.e., the charging cable body 410 extends out of the charging cable module 400, the mode switching interface 320 is not electrically connected to other ports, meaning the potential signal acquisition terminal 210 does not acquire a potential signal and transmits this status (no potential signal acquired) to the wireless charging control module 200. (Reference) Figure 2 As shown, when the charging cable outer end 430 is electrically connected to the mode switching interface 320, the charging cable body 410 is housed in the charging cable module 400, and the potential signal output end 330 and the potential signal acquisition end 210 are electrically connected. The potential signal acquisition end 210 acquires the potential signal and transmits the currently acquired potential signal to the wireless charging control module 200.

[0023] Furthermore, the mode switching module 300 also includes a wired power supply interface 340 and a wireless power supply interface 350, and the wireless control module 200 also includes a charging cable control terminal 220 and a wireless power supply terminal 230. The wired power supply interface 340 is electrically connected to the wired charging power supply terminal 110, and the wireless power supply interface 350 is electrically connected to the wireless power supply terminal 230. That is, the wireless charging control module 200 controls the control system 10 to operate in the first working mode or the second working mode based on the potential signal collected by the potential signal acquisition terminal 210. For example, refer to... Figure 1 As shown, when the charging cable's outer end 430 is electrically connected to the device to be charged 20, and the potential signal acquisition terminal 210 does not acquire a potential signal and transmits this status to the wireless charging control module 200, the charging cable control terminal 220 controls the charging cable interface 310 to be electrically connected to the wired power supply interface 340. The control system 10 is used to perform wired charging on the device to be charged 20. At this time, the wireless power supply terminal 230 of the wireless charging control module 200 also does not acquire a potential signal. (Reference) Figure 2 As shown, when the charging cable's outer end 430 is electrically connected to the mode switching interface 320, and the potential signal acquisition terminal 210 acquires the potential signal and transmits the current potential signal to the wireless charging control module 200, the charging cable control terminal 220 controls the charging cable interface 310 to electrically connect to the wireless power supply interface 350. The control system 10 is used to wirelessly charge the device 20 to be charged. At this time, the wireless power supply terminal 230 of the wireless charging control module 200 can acquire the corresponding potential signal. In general, it can ensure that the second working mode is automatically cut off when the first working mode is working, avoiding mutual interference between the two working modes. Moreover, the two working modes are automatically switched through the charging cable control terminal 220 without the need for additional control circuitry. While ensuring the diverse functions of the dual-charging mode control system 10, it also ensures the stability of the control system 10's operation.

[0024] In summary, the dual-charging-mode control system provided by this invention, through a wireless charging control module, allows for wired charging of the device in two modes. In the first mode, the outer end of the charging cable is electrically connected to the device to be charged, and the charging cable control terminal controls the charging cable interface to be electrically connected to the wired power supply interface. In the second mode, the outer end of the charging cable is electrically connected to a mode switching interface, and the charging cable control terminal controls the charging cable interface to be electrically connected to the wireless power supply interface. In this mode, the control system wirelessly charges the device. By setting up a wireless charging control module to change the electrical connections of multiple interfaces, two charging modes are provided, ensuring the diverse functionality of the dual-charging-mode control system and providing convenience for daily life.

[0025] Continue to refer to Figure 1 and Figure 2As shown, the mode switching module 300 further includes a first line switching unit 360; the first line switching unit 360 includes a switching signal receiving end 361 and a connection contact 362; the charging cable interface 310 includes a positive line interface 310A, which is electrically connected to the connection contact 362; the charging cable control end 220 includes a switching signal output end 220A, which is electrically connected to the switching signal receiving end 361; in the first working mode, the potential signal acquisition end 210 acquires a first potential signal, and the switching signal output end 220A controls the connection contact 362 to be electrically connected to the wired power supply interface 340 based on the first potential signal; in the second working mode, the potential signal acquisition end 210 acquires a second potential signal, and the switching signal output end 220A controls the connection contact 362 to be electrically connected to the wireless power supply interface 350 based on the second potential signal.

[0026] Specifically, the mode switching module 300 also includes a first line switching unit 360. The wireless charging control module 200 controls the first line switching unit 360 through the charging cable control terminal 220 based on the collected potential signal, so as to adjust the control system 10 to work in the first working mode or the second working mode.

[0027] Furthermore, the charging cable interface 310 includes a positive cable interface 310A, and the first line switching unit 360 includes a switching signal receiving end 361 and a connection contact 362. By electrically connecting the positive cable interface 310A and the connection contact 362, the first line switching unit 360 is positioned between the positive cable interface 310A and the wired power supply interface 340 and the wireless power supply interface 350. The switching between the two working modes is achieved based on the adjustment of the connection contact 362 in the first line switching unit 360.

[0028] For details, please refer to Figure 1 As shown, the dual-charging mode control system 10 can operate in the first working mode by default. When the charging cable's outer end 430 is electrically connected to the device 20 to be charged, the potential signal collected by the potential signal acquisition terminal 210 is inconsistent with the potential signal transmitted by the charging cable's outer end 430, meaning the wireless charging control module 200 collects the first potential signal. Furthermore, at this time, the wireless power supply terminal 230 included in the wireless charging control module 200 does not collect potential information, meaning the connecting contact 362 in the first line switching unit 360 is not electrically connected to the wireless power supply interface 350. Therefore, the dual-charging mode control system 10 confirms that it remains operating in the first working mode and can provide wired charging for the device 20 to be charged. Further, in the first working mode, the connecting contact 362 in the first line switching unit 360 is electrically connected to the wired power supply interface 340, ensuring that electrical energy is transmitted from the power supply module 100 to the device 10 to be charged.

[0029] refer to Figure 2As shown, the dual-charging mode control system 10 can operate in the first working mode by default. However, when the charging cable external end 430 is electrically connected to the mode switching interface 320, the potential signal collected by the potential signal acquisition terminal 210 is consistent with the potential signal transmitted by the charging cable external end 430. That is, the wireless charging control module 200 collects the second potential signal. The wireless charging control module 200 adjusts the dual-charging mode control system 10 to change the first working mode to the second working mode. At the same time, the wireless charging control module 200 controls the connecting contact 362 in the first line switching unit 360 to be electrically connected to the wireless power supply interface 350, thus ensuring that the dual-charging mode control system 10 operates in the second working mode and can wirelessly charge the device 20 to be charged.

[0030] Furthermore, the dual-charging mode control system 10 can add a detection point Tx between the wireless power supply interface 350 and the wireless power supply terminal 230 to detect whether the wireless power supply interface 350 and the wireless power supply terminal 230 are conductive. For details, refer to... Figure 3 As shown, in the first operating mode, the dual-charging mode control system 10 detects an abnormal signal at the detection point Tx, indicating that the wireless power supply interface 350 and the wireless power supply terminal 230 are not connected. Therefore, it maintains the first operating mode to provide wired charging for the device 20 to be charged. (Reference) Figure 4 As shown, in the first working mode, the detection signal of the detection point Tx of the dual charging mode control system 10 is normal, that is, the wireless power supply interface 350 and the wireless power supply terminal 230 are connected, and the wireless charging control module 200 adjusts the first working mode to the second working mode.

[0031] Figure 3 This is a schematic diagram illustrating the working principle of a dual-charging mode control system provided in an embodiment of the present invention. Figure 4 This is a schematic diagram illustrating the working principle of another dual-charging mode control system provided in this embodiment of the invention. (Refer to...) Figures 1 to 4 As shown, the mode switching module 300 includes a first switch control unit 371; the first switch control unit 371 includes a first input terminal 371A, a first output terminal 371B and a first control terminal 371C; the first control terminal 371C is electrically connected to the switching signal output terminal 220A, the first input terminal 371A is grounded, and the first output terminal 371B is electrically connected to the switching signal receiving terminal 361.

[0032] The mode switching module 300 further includes a first switch control unit 371. By adding the first switch control unit 371 to the wireless charging control module 200 and the first line switching unit 360, the control system 10 can operate more stably and with higher security. For example, the first switch control unit 371 can be a transistor to improve control stability; however, this embodiment of the invention does not impose specific limitations on this.

[0033] Furthermore, in the first switch control unit 371, the first control terminal 371C is electrically connected to the switching signal output terminal 220A, the first input terminal 371A is grounded, and the first output terminal 371B is electrically connected to the switching signal receiving terminal 361. For example, the first line switching unit 360 can be a relay, and the switching between two operating modes is achieved by controlling the opening or closing of the normally open or normally closed contacts in the relay through the first switch control unit 371. This embodiment of the invention does not impose specific limitations on this aspect.

[0034] For example, refer to Figure 3 As shown, in the first operating mode, the switching signal output terminal 220A is electrically connected to the first control terminal 371C. When the wireless charging control module 200 receives the first potential signal, it controls the first switch control unit 371 to turn off, and then controls the first line switching unit 360 to power off through the first output terminal 371B, ensuring that the connection contact 362 is electrically connected to the wired power supply interface 340. (Reference) Figure 4 As shown, in the second working mode, the switching signal output terminal 220A is electrically connected to the first control terminal 371C. When the wireless charging control module 200 receives the second potential signal, it controls the first switch control unit 371 to turn on, and then controls the first line switching unit 360 to be powered on through the first output terminal 371B, ensuring that the connection contact 362 is electrically connected to the wireless power supply interface 350.

[0035] Continue to refer to Figure 1 and Figure 2 As shown, the mode switching module 300 also includes a second line switching unit 380; the second line switching unit 380 includes a switch signal receiving terminal 380A and a ground interface 380B; the charging cable interface 310 includes a negative wire interface 310B, and the ground interface 380B is electrically connected to the negative wire interface 310B; the charging cable control terminal 220 includes a switch signal output terminal 220B, and the switch signal output terminal 220B is electrically connected to the switch signal receiving terminal 380A; in the first working mode, the potential signal acquisition terminal 210 acquires a first potential signal, and the switch signal output terminal 220B controls the ground interface 380B to connect to the ground terminal 381 based on the first potential signal; in the second working mode, the potential signal acquisition terminal 210 acquires a second potential signal, and the switch signal output terminal 220B controls the ground interface 380B to disconnect from the ground terminal 381 based on the second potential signal.

[0036] Specifically, the mode switching module 300 also includes a second line switching unit 380. The wireless charging control module 200 controls the second line switching unit 380 through the charging cable control terminal 220 based on the received potential signal, realizing the on and off of the second line switching unit 380 in the first or second working mode. The second line switching unit 380 can prevent the control system 10 from disconnecting the negative wire interface 310B and the ground terminal 381 when wirelessly charging the device to be charged 20, thus preventing the connection between the ground wire interface 380B and the ground terminal 381 from generating additional magnetic fields that affect wireless charging. The second line switching unit 380 further improves the reliability and stability of the control system 10.

[0037] Furthermore, the second line switching unit 380 includes a switch signal receiving terminal 380A and a ground interface 380B. The ground interface 380B is electrically connected to the negative line interface 310B. The second line switching unit 380 is located between the ground terminal 381 and the negative line interface 310B. By controlling the on and off states of the second line switching unit 380, the control system 10 can ensure that it charges the device 20 normally in the first operating mode, while ensuring that no additional changing magnetic fields occur in the second operating mode, thus avoiding any adverse effects on wireless charging.

[0038] For example, refer to Figure 1 As shown, the outer end 430 of the charging cable is electrically connected to the device 20 to be charged. The wireless charging control module 200 acquires the first potential signal and transmits the control command to the switch signal receiver 380A through the switch signal output terminal 220B. The ground wire interface 380B is then connected to the ground terminal 381, thus enabling wired charging of the device 20 to be charged. (Reference) Figure 2 As shown, the outer end 430 of the charging cable is electrically connected to the mode switching interface 320. The wireless charging control module 200 collects the second potential signal and transmits the control command to the switch signal receiving end 380A through the switch signal output end 220B. The ground wire interface 380B is disconnected from the grounding end 381 to realize wireless charging for the device to be charged 20. This further avoids the additional magnetic field generated by connecting the ground wire interface 380B and the grounding end 381 from affecting the wireless charging.

[0039] Continue to refer to Figures 1 to 4 As shown, the second line switching unit 380 includes a second switch control unit (372); the second switch control unit 372 includes a second input terminal 372A, a second output terminal 372B, and a second control terminal 372C; the second control terminal 372C is electrically connected to the switch signal output terminal 220B, and the second input terminal 372A and the second output terminal 372B are connected between the negative line interface 310B and the ground terminal 381.

[0040] The second line switching unit 380 includes a second switch control unit 372, which means that the second line switching unit 380 can be controlled more stably by the second switch control unit 372 to turn on and off the second line switching unit 380.

[0041] Furthermore, the second control terminal 372C in the second switch control unit 372 is electrically connected to the switch signal output terminal 220B, wherein the second control terminal 372C is equivalent to the switch signal receiving terminal 380A, and the second input terminal 372A and the second output terminal 372B are connected between the negative line interface 310B and the ground terminal 381. For example, the second switch control unit 372 can be a transistor to improve control stability; however, this embodiment of the invention does not impose specific limitations on this. (See reference...) Figure 3 As shown, in the first operating mode, the switch signal output terminal 220B is electrically connected to the second control terminal 372C. When the wireless charging control module 200 receives the first potential signal, it controls the second switch control unit 372 to turn on, that is, the first potential signal controls the ground interface 380B to connect to the ground terminal 381. (Reference) Figure 4 As shown, in the second operating mode, the switch signal output terminal 220B is electrically connected to the second control terminal 372C. When the wireless charging control module 20 receives the second potential signal, it controls the second switch control unit 372 to turn off, that is, the second potential signal controls the ground interface 380B to turn off the ground terminal 381. The second switch control unit 372 ensures the operational stability of the control system 10.

[0042] Based on the same inventive concept, embodiments of the present invention also provide a control method for a dual-charging-mode control system. Figure 5 This is a flowchart of a control method provided in an embodiment of the present invention, see reference. Figure 5 As shown, the control methods include: S110, Acquire potential signals.

[0043] For example, the potential signal acquisition end and the potential signal output end are electrically connected. The potential signal acquisition end acquires different potential signals based on different connection methods of the inner end of the charging cable and transmits them to the wireless charging control module. Furthermore, the wireless power supply end of the wireless charging control module acquires the current potential signal in real time, and the wireless charging control module uses the acquired potential information. The potential information acquired by the potential signal acquisition end may include the potential information emitted when the outer end of the charging cable is electrically connected to the device to be charged, and also the potential information emitted when the outer end of the charging cable is electrically connected to the mode switching interface. For example, the wireless charging control module may include a microprocessor (MCU).

[0044] S120. Output control signals based on the collected potential signals to control the control system to operate in the first working mode or the second working mode.

[0045] The wireless charging control module determines the operating mode of the dual-mode charger based on the collected potential information. For example, when the charging cable is electrically connected to the device to be charged, the potential signal acquisition terminal of the wireless charging control module collects the first potential information and determines that the control system should operate in the first mode. When the charging cable is electrically connected to the mode switching interface, the potential signal acquisition terminal of the wireless charging control module collects the second potential information and determines that the control system should operate in the second mode.

[0046] Optionally, the control system also includes an adapter; the control method further includes: determining whether the potential signal is an adapter input voltage signal; if so, controlling the control system to switch to the second operating mode; if not, controlling the control system to continue operating in the first operating mode.

[0047] Specifically, the control system also includes an adapter, which is electrically connected to an external power source to provide the necessary power to the device being charged. In the first operating mode, if the potential signal collected by the potential signal acquisition terminal 210 of the wireless charging control module is different from the adapter input voltage signal, it indicates that the external end of the charging cable is not electrically connected to the mode switching interface, and the control system continues to operate in the first operating mode. When the potential signal collected by the potential signal acquisition terminal 210 of the wireless charging control module is the adapter input voltage signal, it indicates that the external end of the charging cable is electrically connected to the mode switching interface, and the control system continues to operate in the first operating mode. Furthermore, by determining whether the voltage signal collected by the potential signal acquisition terminal is the voltage signal output by the adapter, the operating mode can be determined, and based on this determination process, any abnormalities in the operating process can be debugged.

[0048] S131. In the first working mode, the control charging cable interface is electrically connected to the wired power supply interface to control the control system to perform wired charging of the device to be charged.

[0049] For example, when the electrical signal acquired by the potential signal acquisition terminal is inconsistent with the potential signal at the outer end of the charging cable, the acquired potential signal is set as the first potential signal. At this time, the wireless charging control module controls the mode switching module and the power supply module to be electrically connected, that is, the charging cable interface is electrically connected to the wired power supply interface. The wireless power supply terminal also does not acquire a potential signal, that is, there is a potential signal abnormality. In other words, the power supply module provides power to the device to be charged through the mode switching module to realize the wired charging working mode of the control system.

[0050] S132. In the second working mode, the control charging cable interface is electrically connected to the wireless power supply interface to control the control system to wirelessly charge the device to be charged.

[0051] For example, when the potential signal acquired by the potential signal acquisition terminal is consistent with the potential signal at the outer end of the charging cable, i.e., when the acquired potential signal is set as the second potential information, the wireless charging control module's control mode switching module disconnects from the power supply module, i.e., the charging cable interface is electrically connected to the wireless power supply interface. The wireless power supply terminal acquires the corresponding potential signal, and the wireless charging control module is electrically connected to the power supply module. The wireless charging control module provides power to the device to be charged, i.e., the wireless charging of the system is controlled in the second working mode.

[0052] In summary, the control method for a dual-charging-mode control system provided by this invention first acquires a potential signal; then, based on the acquired potential signal, it outputs a control signal to control the control system to operate in either a first or second working mode. In the first working mode, the charging cable interface is electrically connected to the wired power supply interface to control the control system to perform wired charging of the device to be charged; in the second working mode, the charging cable interface is electrically connected to the wireless power supply interface to control the control system to perform wireless charging of the device to be charged. That is, this control method provides a dual-charging-mode control system that can offer two charging modes, ensuring the diverse functionality of the dual-charging-mode control system and providing convenience for daily life.

[0053] Figure 6 This is a flowchart of another control method provided in an embodiment of the present invention, see reference. Figure 6 As shown, the control method also includes: S210, Acquire potential signals.

[0054] S220. Output control signals based on the collected potential signals to control the control system to operate in the first working mode or the second working mode.

[0055] Specifically, the mode switching module also includes a first line switching unit; the first line switching unit includes a switching signal receiving end and a connection contact; the charging cable interface includes a positive line interface, and the charging cable control end includes a switching signal output end; the switching signal output end is electrically connected to the switching signal receiving end.

[0056] In the first working mode: S231. Output the first switching signal to the switching signal receiving end according to the first potential signal, and connect the contact point to the wired power supply interface.

[0057] For example, when the outer end of the charging cable is electrically connected to the device to be charged, the potential signal output terminal is electrically connected to the mode switching interface. When the electrical signal collected by the potential signal acquisition terminal is inconsistent with the potential signal at the outer end of the charging cable, the collected potential signal is set as the first potential signal. That is, the switching signal output terminal of the wireless charging control module changes the electrical connection mode inside the first line switching unit based on the first potential signal, that is, the control contact point is electrically connected to the wired power supply interface, that is, the power supply module is electrically connected to the mode switching module, and the control system performs wired charging in the first working mode.

[0058] S241. Output the first switch signal to the switch signal receiving terminal according to the first potential signal to control the ground wire interface to connect with the ground terminal.

[0059] For example, based on the wireless charging control module acquiring the first potential signal and generating corresponding control commands, the wireless charging control module transmits the control commands to the switch signal receiving end, the switch signal receiving end outputs the first switch signal, and controls the second line switching unit to be turned on based on the first switch signal, adjusts the ground wire interface to be connected to the ground terminal, and combines the positive wire interface and the negative wire interface to perform wired charging for the device to be charged.

[0060] S251. In the first working mode, the control charging cable interface is electrically connected to the wired power supply interface to control the control system to perform wired charging of the device to be charged.

[0061] In the second working mode: S232. Output a second switching signal to the switching signal receiver according to the second potential signal, and connect the contact point to the wireless power supply interface.

[0062] For example, when the charging cable is electrically connected to the mode switching interface, if the potential signal acquisition terminal detects an electrical signal that matches the potential signal at the charging cable's outer end, the wireless charging control module's potential signal acquisition terminal will detect a second potential signal. The switching signal output terminal then changes the internal electrical connection of the first line switching unit based on this second potential signal, i.e., controlling the connection point to connect electrically to the wireless power supply interface. This ensures the power supply module is electrically connected to the wireless charging control module, allowing the wireless charging control module to provide power to the control system in the second operating mode, thus achieving wireless charging.

[0063] S242. Output a second switch signal to the switch signal receiving terminal according to the second potential signal to control the grounding interface to disconnect from the grounding terminal.

[0064] For example, based on the wireless charging control module acquiring the second potential signal and generating corresponding control commands, the wireless charging control module transmits the control commands to the switch signal receiving end. The switch signal receiving end outputs the second switch signal, and based on the second switch signal, controls the second line switching unit to disconnect, adjusting the ground wire interface to disconnect from the grounding terminal. This ensures that while the wireless charging control module wirelessly charges the device to be charged through the positive wire interface, the negative wire interface is disconnected from the grounding terminal, ensuring that the control system is more stable and not affected by other additional magnetic fields.

[0065] S252. In the second working mode, the control charging cable interface is electrically connected to the wireless power supply interface to control the control system to wirelessly charge the device to be charged.

[0066] Furthermore, S260 is executed after determining the first and second operating modes. S260, Check if the wireless power supply attributes are normal.

[0067] For example, during the wireless charging process in the second operating mode, the positive wire inside the charging cable module and the wireless charging control module form a closed coil, and the device to be charged is wirelessly charged through the coil wound around the positive wire in the charging cable module. Furthermore, to ensure the safety and stability of the control system, the attributes of the wireless power supply end are detected during the charging process to improve the stability of the control system. Specifically, detection is performed at the wireless power supply end, refer to... Figure 3 and Figure 4 The detection point Tx in the system. For example, by collecting data from the detection point, it can be determined whether the current charging cable interface and the wireless power supply interface are electrically connected, that is, whether the coil properties are normal. If they are electrically connected, it is determined that the control system is working normally in the second working mode; if they are not electrically connected, it is determined that the control system is not working normally in the second working mode.

[0068] If normal, execute S272 and the control system continues to operate in the second working mode.

[0069] For example, when the current charging cable interface is electrically connected to the wireless power supply interface, it means that the first switch control unit and the first line switching unit in the mode switching module are conducting, the coil properties are normal, and the control system can normally perform wireless charging of the device to be charged in the second working mode. Then the control system continues to work in the second working mode.

[0070] If it is not normal, execute S271 and the control system switches to the first working mode.

[0071] For example, when the current charging cable interface and the wireless power supply interface are not electrically connected, it indicates that the first switch control unit and the first line switching unit in the mode switching module are disconnected, the coil properties are abnormal, the control system cannot normally perform wireless charging of the device to be charged in the second working mode, and needs to switch to the first working mode to perform wired charging of the device to be charged. Then the control system switches to the first working mode and executes S231.

[0072] Figure 7 This is a flowchart of another control method provided in an embodiment of the present invention, see reference. Figure 7 As shown, the control process is further explained in general, and the control methods include: S310, the control system is powered on.

[0073] S320, the control system operates in the first working mode.

[0074] For example, the control system powers on to charge the device to be charged and put it into use, and the control system defaults to first working in the first working mode to perform wired charging of the device to be charged.

[0075] S330, connects the contact point to the wired power supply interface.

[0076] For example, in the first line switching unit, the connection point is electrically connected to the wired power supply interface to ensure that the power supply module performs wired charging for the device to be charged through the mode switching module, and charging is performed in the first working mode.

[0077] S340. Determine whether the potential information acquired by the potential signal acquisition terminal is the potential information transmitted from the external end of the charging cable.

[0078] For example, the potential signal acquisition terminal of the wireless charging control module acquires potential signals. When the potential information acquired by the potential signal acquisition terminal is equal to the potential information transmitted from the external end of the charging cable, it indicates that the external end of the charging cable of the control system is electrically connected to the mode switching interface. In this case, the wireless charging control module in the control system adjusts the first working mode to the second working mode, i.e., executes S350. When the potential information acquired by the potential signal acquisition terminal is not equal to the potential information transmitted from the external end of the charging cable, it indicates that the external end of the charging cable of the control system is not electrically connected to the mode switching interface and continues to be directly electrically connected to the device to be charged. In this case, the control system continues to maintain the first working mode, i.e., executes S320.

[0079] S350, the control system operates in the second working mode.

[0080] S360, connect the contact point and the wireless power interface.

[0081] For example, in the first line switching unit, the connection point is electrically connected to the wireless power supply interface to ensure that the power supply module wirelessly charges the device to be charged through the wireless charging module, and charging is performed in the second working mode.

[0082] S370, check if the properties of the wireless power supply are normal.

[0083] For example, during the wireless charging process in the second operating mode, the positive wire inside the charging cable module and the wireless charging control module form a closed coil, and the device to be charged is wirelessly charged through the coil wound around the positive wire in the charging cable module. Furthermore, to ensure the safety and stability of the control system, the attributes of the wireless power supply end are detected during the charging process to improve the stability of the control system. Specifically, detection is performed at the wireless power supply end, refer to... Figure 3 and Figure 4 The detection point Tx in the process. For example, by collecting data from the detection point, it can be determined whether the current charging cable interface and the wireless power supply interface are electrically connected, that is, whether the coil attribute is normal. If it is normal, S350 is executed; if it is not normal, S320 is executed.

[0084] In summary, the embodiments of the present invention specifically detail how the wireless charging control module ensures the control system can provide two charging modes, guaranteeing the diverse functionality of the dual-charging mode control system and providing convenience for daily life. Furthermore, by real-time monitoring of the charging cable module's properties, the stability of the control system's state is ensured, better realizing the two operating modes.
