[0017] In order to enable those skilled in the art to better understand the technical solution of the present application, the exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0018] In the absence of conflict, the embodiments of the present application and the features therein may be combined with each other.

[0019] As used herein, the term "and / or" includes any and all combinations of one or more related enumerated items. The terms used herein are only used to describe specific embodiments and are not intended to limit the present application. As used herein, the singular forms "a" and "the" are also intended to include the plural forms, unless the context clearly indicates otherwise. It will also be understood that when the terms "including" and / or "made of..." are used in this specification, the presence of the features, wholes, steps, operations, elements and / or components is specified, but the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or groups thereof is not excluded. "Connected" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0020] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this application, and will not be interpreted as having an idealized or overly formal meaning unless explicitly defined herein.

[0021] A control device (e.g., a game controller, operation buttons, etc.) can be connected to a terminal (e.g., a smart phone, tablet computer, etc.) via a wireless connection (e.g., a connection based on a Bluetooth protocol, or a connection based on a mobile hotspot (Wi-Fi), etc.) or a wired connection, so that the control device can be used to operate and control the terminal, thereby increasing the operating efficiency of the terminal.

[0022] When the control device and the terminal are connected by a wired connection, for example, the control device and the terminal are connected by a Universal Serial Bus (USB) interface, the two devices can communicate through the USB interface; but if the terminal needs to be charged at this time, and the USB interface of the terminal is occupied by the operation device, an external charging device of the control device is required to transmit the power provided by the external charging device to the terminal through the control device to charge the terminal.

[0023] However, when the operating device is connected to a charging device, or when the connection between the operating device and the charging device is disconnected, the connection status between the terminal and the operating device will be affected, that is, the terminal and the operating device need to re-establish a communication connection, and the process of re-establishing the communication connection takes 3 to 5 seconds. During this 3 to 5 seconds, the user cannot use the operating device to control the application in progress in the terminal. For example, when a user is using a control device to operate a game running in the terminal, if the control device cannot control the actions of the characters in the game within the consumed time, it will cause the characters in the game to be injured or killed, reducing the user experience.

[0024] The present application provides a terminal, a control device and a charging system to solve the above problems.

[0025] Figure 1 FIG. 1 is a schematic diagram showing a connection between a terminal and a control device provided in an embodiment of the present application. Figure 1 As shown, the terminal 110 includes: a first interface 111 , a second interface 112 and a battery module 113 .

[0026] For example, the terminal 110 may be a smart phone, a tablet computer, etc., and applications such as game software, video software, etc. may be run on the terminal 110 .

[0027] The first interface 111 is used to connect to the third interface 121 of the control device 120 and communicate with the control device 120;

[0028] The second interface 112 is used to connect to the fourth interface 122 of the control device 120 connected to the first interface 111 and charge the battery module 113 .

[0029] The control device 120 may be a device such as a game controller or an external button that can be connected to the terminal 110 and assist the terminal 110 in operating and controlling.

[0030] Among them, being connected to the fourth interface 122 of the control device 120 connected to the first interface 111 means that the terminal 110 and the control device 120 are connected not only through the first interface 111 and the third interface 121, but also through the second interface 112 and the fourth interface 122; that is, while communicating with the control device 120 through the first interface 111, the control device can also be used to charge the battery module 113 through the second interface 112, thereby realizing the simultaneous use of the data transmission interface and the charging interface.

[0031] In this embodiment, by connecting the third interface of the control device through the first interface and communicating with the control device, the control device can assist the terminal in performing corresponding operations and improve the operating efficiency of the terminal; using the second interface to connect to the fourth interface of the control device and using the first interface to connect to the third interface at the same time can reduce the delay caused by the need to re-establish the communication connection between the terminal and the control device due to using one interface for both data transmission and charging, thereby improving the user experience of the terminal.

[0032] In some exemplary embodiments, the first interface 111 is also used to charge the battery module 113; the terminal 110 also includes: a first management module, used to determine whether to select the first interface 111 to charge the battery module 113 based on the power of the battery module 113 and / or application information running on the terminal 110.

[0033] The application information running on the terminal 110 includes at least one of the information of a game application, a conversation application, and a video on demand application running on the terminal 110 .

[0034] When the power level of the battery module 113 is less than or equal to a preset power level threshold (for example, the preset power level threshold is 5% of the power level), it is determined to select the first interface 111 to charge the battery module 113 .

[0035] When the power level of the battery module 113 is greater than a preset power threshold, and the application running on the terminal does not require a control device to control it (for example, the game running on the terminal is in a break, or at the beginning (or end) of the game, etc.), it is determined that the first interface 111 is selected to charge the battery module 113.

[0036] When the power level of the battery module 113 is greater than a preset power threshold, and the application running on the terminal needs to be controlled by a control device (for example, the game running on the terminal is in a fierce battle state, and the user needs to control the character movements in the game through the control device, etc.), it is determined not to select the first interface 111 to charge the battery module 113.

[0037] The first management module selectively uses the first interface 111 to charge the battery module 113 based on the above different conditions, thereby ensuring that the terminal can work normally without affecting the user's operation of the application in the terminal using the control device, which can not only extend the use time of the terminal but also improve the user experience.

[0038] In some exemplary embodiments, the first interface 111 includes a socket, and the second interface 112 includes a contact or a jack.

[0039] When the first interface 111 includes a socket and the second interface 112 includes a contact or a jack, correspondingly, on the control device side, the third interface 121 includes a plug and the fourth interface 122 includes a probe, so that the first interface 111 can be used in conjunction with the third interface 121, and at the same time, the second interface 112 can also be used in conjunction with the fourth interface 122.

[0040] By providing a non-protruding socket, contact or jack on the terminal 110, the terminal 110 can be conveniently used even when it is not connected to the control device 120, so that the appearance of the terminal 110 is regular and convenient for user operation; relatively speaking, a protruding plug and probe are provided on the control device 120, and the control device 120 usually needs to be inserted into the terminal 110 to assist the terminal 110 in operation or control, so that the terminal 110 can better complete the control of the application in the terminal 110 with the assistance of the control device 120.

[0041] In some exemplary embodiments, when the second interface 112 includes contacts, the contacts include a positive contact and a negative contact; and the positive contact and the negative contact are both disposed on the outside of the first interface 111 .

[0042] By arranging both the positive contact and the negative contact on the outside of the first interface 111, for example, arranging the positive contact and the negative contact on one side of the first interface 111 respectively, or arranging the positive contact and the negative contact on both sides of the first interface 111 respectively, the third interface 121 can be connected to the first interface 111 while the positive contact can be connected to the positive probe in the control device and the negative contact can be connected to the negative probe in the control device, thereby ensuring that the first interface 111 and the third interface 121, as well as the second interface 112 and the fourth interface 122 can be connected simultaneously.

[0043] In some exemplary embodiments, the first interface 111 is a universal serial bus interface.

[0044] Among them, the USB interface has the characteristics of plug-and-play and hot-swappable. The USB interface can be applied to the connection between a personal computer and a mobile device, or to the connection between a terminal with a power supply and a control device without a power supply. If the terminal and the control device are connected using a USB interface, it indicates that the communication channel between the terminal and the control device is established based on a preset charging protocol, or a communication channel established based on a preset data transmission protocol.

[0045] In a communication channel established based on a preset charging protocol, the control device can charge the terminal through an external charging device connected to it.

[0046] In the communication channel established based on the preset data transmission protocol, normal data transmission can be performed between the control device and the terminal. For example, the communication channel can also be called an On-The-Go (OTG) channel.

[0047] like Figure 1 As shown, the control device 120 includes: a third interface 121 , a fourth interface 122 and a power module 123 .

[0048] The power module 123 is used to supply power to the fourth interface 122 .

[0049] The third interface 121 is used to connect to the first interface 111 of the terminal 110 and communicate with the terminal 110 .

[0050] The fourth interface 122 is used to connect to the second interface 112 of the terminal 110 connected to the third interface 121 and charge the terminal 110 .

[0051] The power module 123 may be a battery disposed in the control device 120 or an external power supply device connected via an external port. This application does not impose any limitation on this and will not be elaborated herein.

[0052] In this embodiment, by using the third interface 121 to connect to the first interface 111 of the terminal 110 and communicate with the terminal 110, the terminal 110's operating requirements for applications can be expanded, so that the control device 120 can better operate the applications in the terminal 110 and improve the operating efficiency of the terminal 110; the fourth interface 122 is connected to the second interface 112 of the terminal 110 connected to the third interface 121, and the terminal 110 is charged, and the power module 123 can transmit the power in the fourth interface 122 to the terminal 110, thereby extending the standby time of the terminal 110 and improving the user's experience of the terminal.

[0053] In some exemplary embodiments, the power module 123 includes a power interface, and the power interface is used to connect to an external power supply device (not shown in the figure).

[0054] By connecting to an external power supply device through the power interface, the control device can obtain the electric energy provided by the power supply device, so as to use the electric energy to support the normal operation of each module inside the control device, reduce the terminal's input power to the control device, and thus extend the terminal's use time.

[0055] Furthermore, the control device can also use the electric energy provided by the external power supply device to charge the terminal, thereby reducing the electric energy output of the terminal and extending the standby time of the terminal.

[0056] In some exemplary embodiments, the control device 120 further includes: a second management module (not shown in the figure) configured to detect a connection status between the fourth interface 122 and the power supply device.

[0057] Among them, the second management module detects the connectivity status between the fourth interface 122 and the power supply device. When it is determined that the fourth interface 122 and the power supply device are in a state of mutual connectivity, the control device can select the channel between the fourth interface 122 and the second interface 112 to transmit the power input from the power supply device to the terminal 110, so as to facilitate charging of the terminal 110, reduce the power output by the terminal to the control device, and extend the standby time of the terminal.

[0058] When it is determined that the fourth interface 122 and the power supply device are not connected to each other, the control device can select the channel between the first interface 111 and the third interface 121 to transmit the power input from the power supply device to the terminal 110, so as to charge the terminal 110, reduce the power output from the terminal to the control device, and extend the standby time of the terminal.

[0059] In some exemplary embodiments, the third interface 121 is further used to connect to a power supply device to supply power to the terminal 110 under the control of the second management module.

[0060] When the second management module detects that the terminal 110 and the control device 120 are connected only through the channel between the first interface 111 and the third interface 121, the second management module controls the current input by the power supply device to pass through the channel between the first interface 111 and the third interface 121 to supply power to the terminal 110, so as to reduce the amount of power output by the terminal 110 to the control device 120 and extend the standby time of the terminal 110.

[0061] In some exemplary embodiments, the third interface 121 includes a plug, and the fourth interface 122 includes a probe.

[0062] When the third interface 121 includes a plug and the fourth interface 122 includes a probe, correspondingly, on the terminal side, the first interface 111 includes a socket and the second interface 112 includes a contact or a jack, so that the first interface 111 can be used in conjunction with the third interface 121, and the second interface 112 can also be used in conjunction with the fourth interface 122.

[0063] By providing a protruding plug and a probe on the control device 120, and the control device 120 usually needs to be inserted into the terminal 110 to assist the terminal 110 in operating or controlling, the terminal 110 can better control the application in the terminal 110 with the assistance of the control device 120.

[0064] Two communication channels can be provided between the terminal and the control device, namely, a first communication channel between the first interface 111 and the third interface 121, and a second communication channel between the second interface 112 and the fourth interface 122, thereby expanding the connection mode between the terminal and the control device so that the control device can better operate the terminal.

[0065] In some exemplary embodiments, the plug and the probe both protrude from the outer surface of the control device 120 ; the probe includes a positive probe and a negative probe, and the positive probe and the negative probe are both disposed on the outer side of the third interface 121 .

[0066] By arranging both the positive probe and the negative probe on the outside of the third interface 121, for example, arranging the positive probe and the negative probe on one side of the third interface 121 respectively, or arranging the positive probe and the negative probe on both sides of the third interface 121 respectively, the third interface 121 can be connected to the first interface 111 while the positive probe can be connected to the positive contact in the terminal and the negative probe can be connected to the negative contact in the terminal, thereby ensuring that the first interface 111 and the third interface 121, as well as the second interface 112 and the fourth interface 122, can be connected simultaneously.

[0067] In some exemplary embodiments, a telescopic component is disposed at the bottom of the probe; the telescopic component is used to control the connection between the second interface 112 and the fourth interface 122 under the action of an external force.

[0068] Through the control of the telescopic component (eg, a spring, a spring, etc.), the second interface 112 and the fourth interface 122 can be brought into close contact, so that the two interfaces will not be easily loosened, thereby improving the connection stability between the interfaces.

[0069] In some exemplary embodiments, the control device further includes: an additional functional module (not shown in the figure); and a power module 123, which is also used to supply power to the additional functional module.

[0070] Among them, the accessory function module includes at least one of a button, a joystick, an indicator light, a decorative light, and a fan.

[0071] The input current is distributed to each additional functional module in the control device by using the power module 123 to maintain the power supply of each additional functional module, so that each additional functional module cooperates with each other, better completes the operation requirements of the terminal, and improves the user experience.

[0072] Figure 2 FIG. 1 is a block diagram showing a charging system according to an embodiment of the present application. Figure 2 As shown, the charging system includes: a terminal 201 , a control device 202 and a power supply device 203 .

[0073] The terminal 201 is connected to the control device 202 , and the power supply device 203 is connected to the control device 202 .

[0074] Terminal 201 is configured as any terminal in the embodiments of the present application.

[0075] For example, terminal 201 includes: a battery module, a first interface and a second interface; the first interface is used to connect to the third interface of the control device and communicate with the control device; the second interface is used to connect to the fourth interface of the control device connected to the first interface and charge the battery module.

[0076] The control device 202 is configured as any one of the control devices in the embodiments of the present application.

[0077] For example, the control device 202 includes: a power module, a third interface and a fourth interface; the power module is used to supply power to the fourth interface; the third interface is used to connect to the first interface of the terminal and communicate with the terminal; the fourth interface is used to connect to the second interface of the terminal connected to the third interface and charge the terminal.

[0078] The power supply device 203 is configured to charge the terminal 201 through the control device 202 .

[0079] In this embodiment, the terminal is connected to the third interface of the control device through the first interface of the terminal, so that the terminal and the control device communicate, and the control device can assist the terminal in performing corresponding operations, thereby improving the operation efficiency of the terminal; the second interface of the terminal is connected to the fourth interface of the control device, and the control device is a device connected to the first interface; in other words, the terminal and the control device are connected not only through the first interface and the third interface, but also through the second interface and the fourth interface at the same time; that is, while communicating with the control device through the first interface, the control device can also be used to charge the battery module through the second interface, which can reduce the delay caused by the need to re-establish the communication connection between the terminal and the control device due to the use of one interface for both data transmission and charging, and the fourth interface can also be used to transmit the power provided by the power supply device to the terminal to facilitate charging of the terminal, reduce the power consumption of the battery module in the terminal, delay the standby time of the terminal, and improve the user experience of the terminal.

[0080] Figure 3 FIG. 1 is a block diagram showing a charging system according to an embodiment of the present application. Figure 3 As shown, the charging system includes: a terminal 310 , a control device 320 and a power supply device 330 .

[0081] The terminal 310 includes a processor 311 , a power management module 312 , a first charging management module 313 , a battery module 314 , a first interface 315 and a second interface 316 .

[0082] The control device 320 includes a third interface 321 , a fourth interface 322 , a control module 323 , a second charging management module 324 and a power interface 325 .

[0083] The processor 311 is used to control the power management module 312 and the first charging management module 313 .

[0084] The power management module 312 is used to communicate with the control device 320 through the first interface 315 and the third interface 321. The types of communication include OTG connection based on data exchange and USB connection.

[0085] Among them, OTG connection is a connection that allows data transmission between different devices or mobile devices without a host. USB connection is a connection between a personal computer and a mobile device through technical specifications between an input interface and an output interface. In this embodiment, OTG connection can be simply understood as a connection for data transmission only, and USB connection is a connection for charging the device.

[0086] The first charging management module 313 is used to determine whether to select the first interface 315 to charge the battery module 314 and to supply power to the processor 311 and the power management module 312 according to the power level of the battery module 314 and / or the application information running on the terminal 310 .

[0087] The battery module 314 is used to supply power to various modules in the terminal 310 (for example, the first charging management module 313, the processor 311, the power management module 312, the first interface 315 and the second interface 316, etc.).

[0088] The first interface 315 is used to physically contact the third interface 321 of the control device 320 and establish an OTG connection or a USB connection with the control device according to the management instruction sent by the power management module 312 .

[0089] The second interface 316 is used to physically contact with the first four interfaces 322 of the control device 320 and charge the battery module 314 according to the management instruction sent by the first charging management module 313 .

[0090] The control module 323 is used to control each module in the control device 320 and distribute the current input by the power supply device 330 through the power interface 325 to each module in the control device 320 to maintain the power supply of each module.

[0091] The power supply device 330 can also supply power to an accessory function module (not shown in the figure) in the control device 320. For example, the accessory function module includes at least one of: a button, a joystick, an indicator light, a decorative light, and a fan.

[0092] The second charging management module 324 is used to detect the connectivity between the fourth interface 322 and the power supply device 330 , and to control the current inputted by the power interface 325 , to charge the terminal 310 through the fourth interface 322 or the third interface 321 , and to supply power to the control module 323 .

[0093] The third interface 321 is used to physically contact the first interface 315 in the terminal 310 and establish an OTG connection or a USB connection with the terminal 310 according to a connection management instruction sent by the control module 323 .

[0094] The fourth interface 322 is used to physically contact the second interface 316 in the terminal 310 and transmit current to the second interface 316 in the terminal 310 according to the control instruction sent by the second charging management module 324, so as to charge the battery module 314 in the terminal 310.

[0095] The power interface 325 is used to connect to the power supply device 330 and transmit the charging current input by the power supply device 330 to the second charging management module 324 .

[0096] Among them, when the first interface 315 includes a socket and the second interface 316 includes a contact or a jack, the third interface 321 includes a plug and the fourth interface 322 includes a probe, so that the first interface 315 and the third interface 321 can be used in conjunction with each other, and the second interface 316 and the fourth interface 322 can also be matched at the same time.

[0097] In some embodiments, when the second interface 316 includes contacts, the contacts include a positive contact and a negative contact; and the positive contact and the negative contact are both disposed on the outside of the first interface 315 .

[0098] In some embodiments, the plug and the probe both protrude from the outer surface of the control device 320; the probe includes a positive probe and a negative probe, and the positive probe and the negative probe are both arranged outside the third interface 321. A telescopic component is arranged at the bottom of the probe. The telescopic component is used to control the connection between the second interface 316 and the fourth interface 322 under the action of an external force.

[0099] Through the control of the telescopic component (eg, a spring, a spring, etc.), the second interface 316 and the fourth interface 322 can be brought into close contact, so that the two interfaces will not be easily loosened, thereby improving the connection stability between the interfaces.

[0100] Figure 4 FIG. 1 is a schematic diagram showing a connection between a terminal and a control device provided in an embodiment of the present application. Figure 4 As shown, the terminal 410 is connected to the control device 420 via different interfaces.

[0101] The first USB interface 411 in the terminal 410 corresponds to the second USB interface 421 in the control device 420 .

[0102] The first positive contact (eg, voltage bus (VBUS) metal contact) 412 corresponds to the first positive probe (eg, VBUS metal probe) 422 .

[0103] The first cathode contact (eg, a ground point (Ground, GND) metal contact) 413 corresponds to the first cathode probe (eg, a GND metal probe) 423 .

[0104] like Figure 4 As shown, the first positive contact 412 and the first negative contact 413 are located on the left and right sides of the first USB interface 411; correspondingly, the first negative probe 423 and the first positive probe 422 are located on the left and right sides of the second USB interface 421. In addition, the height of the first positive probe 422 and the first negative probe 423 protruding from the outer surface of the control device 420 is lower than the height of the second USB interface 421 protruding from the outer surface of the control device 320.

[0105] When the first USB interface 411 and the second USB interface 421 are connected and fully fitted, under the clamping action of the terminal 310 and the control device 420, the first positive contact 412 and the first positive probe 422 are in contact and connected, and at the same time, the first negative contact and the first negative probe 423 are also in contact and connected.

[0106] For example, Figure 5 A schematic diagram showing a connection between a terminal and a control device provided in an embodiment of the present application is shown. Figure 5 The interfaces in Figure 4 The interfaces shown are the same and will not be described again. Figure 5 As shown, the terminal 410 is connected to the control device 420 through various interfaces. When the first USB interface 411 in the terminal 410 is connected to the second USB interface 421 in the control device 420, the first positive contact 412 and the first positive probe 422 are connected to each other; the first negative contact 413 and the first positive probe 423 are also connected to each other.

[0107] Through the above connection, the terminal 410 can transmit communication data to the control device 420 through the connection link between the first USB interface 411 and the second USB interface 421; at the same time, the control device 420 can also charge the terminal 410 through the connection link between the first positive contact 412 and the first positive probe 422, and the connection link between the first negative contact 413 and the first positive probe 423. The delay caused by the need to re-establish the communication connection between the terminal and the control device due to using one interface for both data transmission and charging can be reduced, the power consumption of the battery module can be reduced, the standby time of the terminal can be delayed, and the user experience of the terminal can be improved.

[0108] Figure 6 A schematic diagram of a charging method provided in an embodiment of the present application is shown. Figure 6 As shown, the charging method includes but is not limited to the following steps.

[0109] Step S601: The terminal is connected to the control device, and the terminal enters the OTG output mode.

[0110] When the terminal is inserted into the control device, the terminal is connected to the third interface in the control device through the first interface therein, and the power management module 312 communicates with the control module 323 .

[0111] Among them, the OTG output mode is that the terminal supplies power to the control device, in other words, the current flows from the terminal to the control device. In addition, while the terminal supplies power to the control device, data is transmitted between the terminal and the control device.

[0112] When the current enters the control device through the third interface, the current can be used to power various modules in the control device (for example, the second charging management module, buttons, joysticks, indicator lights, decorative lights and fans, etc.).

[0113] Step S602: The control device detects whether it is connected to the power supply device.

[0114] For example, when the control device is working, it detects whether the power interface therein is connected to the power supply device.

[0115] When it is detected that there is no connection between the control device and the power supply device, step S603 is executed; when it is detected that the control device and the power supply device are connected, step S604 is executed.

[0116] Step S603: the terminal maintains the OTG output mode unchanged.

[0117] Step S604: The control device detects whether the fourth interface thereof is connected to the second interface in the terminal.

[0118] For example, the control module in the control device detects whether the metal probe in the fourth interface is connected to the metal contact in the second interface. The metal probe includes a positive probe and a negative probe, and the metal contact includes a positive contact and a negative contact. The positive probe is connected to the positive contact, and the negative probe is connected to the negative contact.

[0119] When it is detected that the fourth interface is connected to the second interface in the terminal, the control module in the control device communicates with the power management module in the terminal through the connection channel between the third interface and the first interface. For example, the control module sends a charging request to the power management module, and the charging request includes a target channel (i.e., the channel between the second interface and the fourth interface); in response to the charging response fed back by the power management module, it is determined that the power management module in the terminal allows the use of the target channel, and then step S605 is executed.

[0120] When it is detected that the fourth interface is not connected to the second interface in the terminal, step S608 is executed.

[0121] Step S605: Control the device to charge the terminal through the fourth interface, and the first interface of the terminal maintains the OTG output mode unchanged.

[0122] The control module controls the power supply device to output the input current to the terminal through the fourth interface, so as to charge the terminal; and the power input by the power supply device is also used to maintain the normal operation of each module in the control device. At this time, since the power supply device can supply power to each module in the control device, the amount of power flowing into the third interface of the control device through the first interface of the terminal will be reduced accordingly until the terminal does not flow current into the control device through the first interface. In the above process, the first interface of the terminal maintains the OTG output mode unchanged.

[0123] Part of the current entering the control device is used to maintain the normal operation of each module in the control device, and the other part enters the terminal through the channel between the second interface and the fourth interface.

[0124] The current entering the terminal is distributed under the control of the control module (or the first charging management module 313) so that a part of the current is used to charge the battery module in the terminal and the other part is used to maintain the operation of each module in the terminal.

[0125] When the terminal detects that the battery module is fully charged, the control module (or the first charging management module 313) can allocate all the current used to charge the battery module to other modules in the terminal to maintain the normal operation of other modules and stop charging the battery module.

[0126] Step S606: When it is determined that the connection between the power supply device and the control device is disconnected, the control device stops charging the terminal.

[0127] For example, if the user removes the charging device connected to the control device, the control device stops charging the terminal, and the charging device no longer supplies power to the control device. At this time, the current flowing from the terminal to the control device through the channel between the first interface and the third interface will increase, so as to maintain the normal operation of each module in the control device.

[0128] Step S607: the first interface of the terminal maintains the OTG output mode unchanged.

[0129] The first interface and the third interface are still in OTG output mode, that is, data is still transmitted between the terminal and the control device through the channel between the first interface and the third interface.

[0130] Step S608: the terminal exits the OTG output mode and reestablishes the USB connection with the control device, and the control device charges the terminal through the third interface.

[0131] It should be noted that since it is detected that the second interface and the fourth interface are not connected, but the channel between the first interface and the third interface is connected, it means that current cannot be transmitted between the control device and the terminal through the channel between the second interface and the fourth interface, but current can be transmitted through the channel between the first interface and the third interface.

[0132] At this time, the terminal exits the OTG output mode, and then the terminal establishes a USB connection with the control device through the channel between the second interface and the fourth interface. When it is determined that the USB connection is successfully established, the control device transmits the current input by the power supply device to the terminal through the channel between the third interface and the first interface, so as to charge the terminal.

[0133] A part of the current entering the control device is used to maintain the normal operation of each module in the control device, and the other part enters the terminal through the channel between the first interface and the third interface.

[0134] The current entering the terminal is distributed under the control of the control module (or the first charging management module 313) so that a part of the current is used to charge the battery module in the terminal and the other part is used to maintain the operation of each module in the terminal.

[0135] When the terminal detects that the battery module is fully charged, the control module (or the first charging management module 313) can allocate all the current used to charge the battery module to other modules in the terminal to maintain the normal operation of other modules and stop charging the battery module.

[0136] Step S609: When it is determined that the connection between the power supply device and the control device is disconnected, the control device stops charging the terminal.

[0137] For example, if the user removes the charging device connected to the control device, the control device stops charging the terminal, and the charging device no longer supplies power to the control device. At this time, the current flowing from the terminal to the control device through the channel between the first interface and the third interface will increase, so as to maintain the normal operation of each module in the control device.

[0138] Step S610: The terminal terminates the USB connection with the control device and re-establishes an OTG connection with the control device.

[0139] The USB connection between the terminal and the control device established through the channel between the first interface and the third interface is terminated. In other words, the control device no longer charges the terminal. Then, the terminal and the control device will establish an OTG connection again through the channel between the first interface and the third interface, so as to use the channel between the first interface and the third interface for data transmission.

[0140] It should be noted that when the terminal enters the OTG output mode, current flows from the terminal to the control device. After the current enters the control device, the current is used to maintain the normal operation of each module in the control device.

[0141] In this embodiment, the control device detects whether it is connected to the power supply device, and when it is determined that it is connected to the power supply device, the control device continues to detect whether its fourth interface is connected to the second interface in the terminal, so as to determine whether different interfaces are used to connect and communicate with the control device. When it is determined that the fourth interface is connected to the second interface, the first interface is used to connect to the third interface of the control device and communicate with the control device, so that the control device can assist the terminal in performing corresponding operations and improve the operation efficiency of the terminal; the second interface is used to connect to the fourth interface of the control device, and the control device is a device connected to the first interface; in other words, the terminal and the control device are connected not only through the first interface and the third interface, but also through the second interface and the fourth interface; that is, while communicating with the control device through the first interface, the control device can also be used to charge the battery module through the second interface, which can reduce the delay caused by the need to re-establish the communication connection between the terminal and the control device due to the use of one interface for both data transmission and charging, and can also reduce the power consumption of the battery module, delay the standby time of the terminal, and improve the user experience of the terminal. When it is determined that the fourth interface is not connected to the second interface, the channel between the first interface and the third interface is used to transmit data between the terminal and the control device, and to charge the terminal, thereby extending the standby time of the terminal.

[0142] Figure 7 A schematic diagram of a charging method provided in an embodiment of the present application is shown. Figure 7 As shown, the charging method includes but is not limited to the following steps.

[0143] Step S701: The terminal is connected to the control device, and the terminal enters the OTG output mode.

[0144] Step S702: The control device detects whether it is connected to the power supply device.

[0145] When it is detected that there is no connection between the control device and the power supply device, step S703 is executed; when it is detected that the control device and the power supply device are connected, step S704 is executed.

[0146] Step S703: the terminal maintains the OTG output mode unchanged.

[0147] Step S704: The control device detects whether the fourth interface thereof is connected to the second interface in the terminal.

[0148] When it is detected that the fourth interface is connected to the second interface in the terminal, step S705 is executed; when it is detected that the fourth interface is not connected to the second interface in the terminal, step S708 is executed.

[0149] Step S705: Control the device to charge the terminal through the fourth interface, and the first interface of the terminal maintains the OTG output mode unchanged.

[0150] Step S706: When it is determined that the connection between the power supply device and the control device is disconnected, the control device stops charging the terminal.

[0151] Step S707: the first interface of the terminal maintains the OTG output mode unchanged.

[0152] It should be noted that steps S701 to S707 in this embodiment are similar to Figure 6 Steps S601 to S607 in the illustrated embodiment are the same and will not be described in detail herein.

[0153] Step S708: The control device determines whether the terminal needs to be charged immediately.

[0154] Among them, the judgment conditions include: when the real-time power of the terminal is less than or equal to a preset power threshold (for example, the preset power threshold is 5% of the power), it is determined that the terminal needs to be charged immediately; when the real-time power of the terminal is greater than the preset power threshold, and the application running on the terminal does not require a control device to control it (for example, the game running on the terminal is in a break, or at the beginning (or end) of the game, etc.), it is determined that the terminal needs to be charged immediately; when the real-time power of the terminal is greater than the preset power threshold, and the application running on the terminal needs to be controlled by a control device (for example, the game running on the terminal is in a fierce battle state, and the user needs to control the character movements in the game through the control device, etc.), it is determined that the terminal does not need to be charged immediately.

[0155] If it is determined that the terminal needs to be charged immediately, step S710 is executed; if it is determined that the terminal does not need to be charged immediately, step S709 is executed.

[0156] Step S709: the first interface of the terminal maintains the OTG output mode unchanged, and the control device does not charge the terminal.

[0157] It should be noted that after executing step S709, the process returns to step S708 to continue determining whether the terminal needs to be charged immediately, and then executes step S710 until it is determined that the terminal needs to be charged immediately.

[0158] Step S710: The terminal exits the OTG output mode and reestablishes the USB connection with the control device, and the control device charges the terminal through the third interface.

[0159] When it is determined that the USB connection between the terminal and the control device is successfully established, the current provided by the power supply device that flows into the control device through the power interface will enter the terminal through the channel between the third interface and the first interface, so as to charge the battery module in the terminal.

[0160] Step S711: When it is determined that the connection between the power supply device and the control device is disconnected, the control device stops charging the terminal.

[0161] Step S712: The terminal terminates the USB connection with the control device and re-establishes an OTG connection with the control device.

[0162] It should be noted that steps S711 to S712 in this embodiment are similar to Figure 6 Steps S609 to S610 in the illustrated embodiment are the same and will not be described in detail herein.

[0163] In this embodiment, the control device determines whether the terminal needs to be charged immediately based on the real-time power level of the terminal and the application information running on the terminal. When the power level of the terminal is very low (for example, 5% or less), the terminal can be charged in time to ensure the normal operation of the terminal. When the real-time power level of the terminal is greater than the preset power threshold and the application running on the terminal does not require the control device to control it, the OTG output mode of the first interface of the terminal is kept unchanged, and the control device does not charge the terminal, which can reduce the number of times the connection between the terminal and the control device is re-established, so that the terminal can match the control device, better meet the user's operating needs, and enhance the user's usage experience.
