As Figure 3 shown, the first charging device C includes a metal spring interface C1 connected to the interface B1 on the power supply component, a power interface C2, a power indicator C3, etc.

[0045] It should be noted that in the embodiment of the present invention, the power supply component B can be connected to the terminal A and charged on the first charging device C (special charger) or the second charging device (general wireless charger), or can be placed alone on the first charging device C or the second charging device for charging. And the first charging device C in the embodiment of the present invention supports both wired charging and wireless charging methods, while the second charging device is a wireless charger that supports the standard wireless charging protocol. When the power supply component B is connected to the terminal A and placed on the first charging device C for charging, due to the electromagnetic induction technology supporting communication within a short distance, non-contact wireless charging can be achieved when the power supply component B and the terminal A are connected and placed on the first charging device C.

[0046] Based on the above Figure 1 mobile terminal A, Figure 2 power supply component B, and Figure 3 first charging device C, Figure 4 The following is a control structure diagram of the terminal A, the power supply component B, and the first charging device C in the embodiment of the present invention. As Figure 4 shown, specifically:

Among them, the power interface A1012 and the power interface B1022 of the power component B can communicate with each other to indicate whether terminal A and power component B are connected correctly with the correct positive and negative poles. Different from the prior art, the detection and control interface is a newly added interface for interacting with the detection and control interface B1023 of the power component B to feedback the signal strength. In addition, the IO interface A1014, the audio module A1015, the display and touch A1016, and the radio frequency unit A1017 are all existing designs that interact with the processor A1011 to jointly implement the functions of the terminal.

Among them, the power interface B1022 and the newly added detection and control interface B1023 are carried on the metal shrapnel interface B1. The power interface B1022 can communicate with the power interface A1012 of terminal A or the power interface C1032 of the first charging device C to indicate whether power supply component B and terminal A or the first charging device C are connected correctly with the correct positive and negative poles. The newly added detection and control interface B1023 has a detection and recognition function. By interacting with the detection and control interface A1013 of terminal A or the detection and control interface C1033 of the first charging device C, it detects the signal strength and feeds back the current connection status of power supply component B to the power charging control and management B1021, including: connected to terminal A or connected to the first charging device C. The wireless charging receiving module B1024 receives electromagnetic wave signals and converts them into current signals through receiving the electromagnetic wave signals of the first charging device C or the second charging device and feeds them back to the power charging control and management B1021. It should be noted that in the embodiments of the present invention, the connection indication on the power interface B1022, the signal strength detected on the detection and control interface B1023, and the electromagnetic wave signals all belong to the connection signals of the embodiments of the present invention.

By interacting with C1032 - C1035, it realizes the control of each functional component, such as controlling the wireless charging receiving module C1035 through the wireless charging standard Send an electromagnetic wave signal to the power supply component B. It should be noted that in the first charging device C, the power interface C1032 and the detection and control interface C1033 are carried on the metal elastic contact interface C1. Among them, the power interface C1032 can communicate with the power interface B1022 of the power supply component B to indicate whether the terminal A and the power supply component B are connected in the correct way; and the newly added detection and control interface C1033 is used to interact with the detection and control interface B1023 of the power supply component B and feedback the signal strength on the metal elastic contact interface C1 to the wireless charging control and management C1031.

[0050] In the embodiment of the present invention, the power supply component can be charged integrally with the terminal, or can be separately placed on the first charging device or the second charging device for charging.

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0052] Embodiment 1

[0053] The embodiment of the present invention provides a charging control method, which is applied to a power supply component separated from the terminal. Figure 5 For the flowchart of a charging control method proposed in the embodiment of the present invention, as Figure 5 shown, in the embodiment of the present invention, the charging control method may include the following steps:

[0054] S301. Receive a connection signal and obtain the signal type and signal strength of the connection signal.

[0055] In the embodiment of the present invention, after the power supply component is connected to the terminal, the first charging device or the second charging device, a connection signal will be received, so that the signal type and signal strength of the connection signal can be obtained.

[0056] It should be noted that in the embodiment of the present invention, the connection signal can be received through the metal elastic contact interface B1 on the power supply component, or through the built-in wireless charging receiving module B2 in the power supply component. Exemplarily, the connection signal received on the metal elastic contact interface B1 can be a voltage signal; the signal received on the wireless charging receiving module B2 can be an electromagnetic wave signal.

[0057] Further, in the embodiment of the present invention, the signal type includes a metal elastic contact voltage signal and an electromagnetic wave signal; the signal strength includes the magnitude of the voltage.

[0058] S302. Determine the charging mode according to the preset charging protocol, signal type, and / or signal strength; where the signal type, signal strength correspond to the preset charging protocol, indicating the current connection method of the power supply component.

[0059] In an embodiment of the present invention, according to a preset charging protocol, after obtaining the signal type and signal strength, the charging mode can be determined. It should be noted that the preset charging protocol corresponds to the signal type and signal strength of the connection signal received by the power supply component, and the signal type and signal strength of the connection signal characterize the current connection method of the power supply component.

[0060] Furthermore, in an embodiment of the present invention, the connection method of the power supply component includes: whether the power supply component is connected to the terminal, or connected to the first charging device or the second charging device.

[0061] Specifically, when the power supply component is connected to the terminal for charging, it includes charging the terminal in a wired manner or in a wireless manner; when the power supply component is connected to the first charging device for charging, it includes connecting to the first charging device in a wired manner or in a wireless manner. It should be noted that in the embodiment of the present invention, the power supply component is only connected to the second charging device in a wireless manner.

[0062] In an embodiment of the present invention, when determining the charging mode, the signal type of the connection signal can be judged by the shrapnel voltage signal received by the metal shrapnel interface B1 of the power supply component and the electromagnetic wave signal received by the wireless charging receiving module B1024. Further, the specific connection method can be determined according to the signal strength of different signal types or only through the signal type. As Figure 4 described, the metal shrapnel interface B1 includes a power interface B1022 and a detection and control interface B1023. The power interface B1022 is used to characterize whether the power supply component is connected in the correct way, such as whether the positive and negative poles of the power supply component are correctly corresponding, and the detection and control interface B1023 is used to detect the signal strength of the shrapnel voltage signal. In addition, different electromagnetic wave signals can also be received in the wireless charging receiving module B1024.

[0063] Specifically, when Figure 4When there is a connection signal on the power interface B1022 shown in the figure, it indicates that the connection is made in the form of a metal shrapnel. At this time, the power supply component may be connected to the terminal or separately connected to the first charging device. Further, when the power supply component determines whether it is connected to the terminal or connected to the first charging device in the form of a metal shrapnel, it is determined by detecting the signal strength on the control interface B1023. Specifically, when the signal strength is the first preset strength, the corresponding preset charging protocol is the wired slow charging protocol, indicating that the power supply component is connected to the terminal in a wired manner. At this time, the charging mode is wired small current charging; when the signal strength is the second preset strength, the corresponding preset charging protocol is the wired fast charging protocol, indicating that the power supply component is connected to the first charging device in a wired manner. At this time, the corresponding charging mode is wired fast charging. Thus, based on the preset charging protocol, when the signal type is the shrapnel voltage signal, different charging modes are determined by the different signal strengths on the metal shrapnel.

[0064] When Figure 4 there is no connection signal on the power interface B1022 shown in the figure, and an electromagnetic wave signal is received on the wireless charging receiving module B1024, the corresponding charging mode is determined by the different types of electromagnetic wave signals. Specifically, when the signal type is the first electromagnetic wave signal, the corresponding preset charging protocol is the wireless slow charging protocol, indicating that the power supply component is connected to the terminal and the first charging device or the second charging device in a wireless manner. At this time, the charging mode is wireless small current charging; when the signal type is the second electromagnetic wave signal, the corresponding preset charging protocol is the first wireless fast charging protocol, indicating that the power supply component is connected to the first charging device in a wireless manner. At this time, the charging mode is the first wireless fast charging; when the signal type is the third electromagnetic wave signal, the corresponding preset charging protocol is the second wireless fast charging protocol, indicating that the power supply component is connected to the second charging device in a wireless manner. At this time, the charging mode is the second wireless fast charging. Thus, based on the preset charging protocol, when different types of electromagnetic wave signals are received on the wireless charging receiving module B1024, the corresponding charging modes are determined. Different types of electromagnetic wave signals are reflected in the different contents carried by the electromagnetic wave signals. Exemplarily, after the electromagnetic wave signal is converted into a digital signal, the binary data forms corresponding to the digital signals are different.

[0065] It should be noted that in the embodiments of the present invention, when the power supply component confirms whether it is connected to the terminal or to the first charging device in the form of a metal shrapnel, it can be determined not only by the signal strength of a single pin on the metal shrapnel, but also by the signal strengths on different pins of the metal shrapnel, that is, different pin types correspond to different connection methods. Exemplarily, different pins are included on the detection and control interface B1023 of the metal shrapnel B1. When there is a signal strength on the first preset pin, or the signal strength is the first preset strength, and there is no signal strength on the second preset pin, it indicates that the power supply component is connected to the terminal. At this time, the corresponding charging mode is wired small current charging. When there is no signal strength on the first preset pin, there is a signal strength on the second preset pin, or the signal strength is the second preset strength, it indicates that the power supply component is connected to the first charging device. At this time, the corresponding charging mode is wired fast charging.

[0066] However, when there is a connection signal on the power interface B1022, and there is no signal strength on the pins of the detection and control interface B1023, and there is an electromagnetic wave signal in the wireless charging receiving module B1024 of the power supply component, it can be determined that the power supply component is connected to the terminal and contacts the external power supply wirelessly. At this time, the electromagnetic wave signal is the first electromagnetic wave signal, and the corresponding preset charging protocol is the wireless slow charging protocol, and the charging mode is wireless small current charging. Thus, based on the preset charging protocol, when there are only the connection signal indicating correct connection in the shrapnel and the electromagnetic wave signal in the wireless charging receiving module B1024 in the signal type, the wireless small current charging mode is determined.

[0067] Furthermore, in the embodiments of the present invention, when there is no connection signal on the power interface B1022, and there is an electromagnetic wave signal in the wireless charging receiving module B1024 of the power supply component, and the electromagnetic wave signal is the second electromagnetic wave signal, the corresponding preset charging protocol at this time is the first wireless fast charging protocol, indicating that the power supply component is connected to the first charging device wirelessly, and the charging mode is the first wireless fast charging; when the electromagnetic wave signal type is the third electromagnetic wave signal, the corresponding preset charging protocol at this time is the second wireless fast charging protocol, indicating that the power supply component is connected to the second charging device wirelessly, and the charging mode is the second wireless fast charging.

[0068] S303. Charge according to the charging mode.

[0069] In the embodiments of the present invention, after the power supply component confirms the charging mode, the power charging control and management B1021 in the power supply component can perform corresponding charging control and management according to the confirmed charging mode.

[0070] It should be noted that in the embodiments of the present invention, there is also a possibility that the power supply component is placed in the terminal, connected to an external power supply through a charging cable together with the terminal, and at the same time placed on the first charging device or the second charging device. At this time, there is a connection signal on the power interface B1022 of the metal shrapnel B1 of the power supply component, and there is a signal strength on the detection control interface B1023. At the same time, there is an electromagnetic wave signal in the wireless charging receiving module B1024 of the power supply component. Regardless of the size of the electromagnetic wave signal, according to the regulations of the prior art, the power charging control and management B1021 will default to charge in the charging mode of wired small current charging.

[0071] In the process of the power charging control and management B1021 performing charging management, it includes: before charging according to the charging mode, the power charging control and management B1021 detects the current power of the power supply component. When the power is lower than the preset power threshold, the power supply component enters the charging mode. Otherwise, when the power is saturated, it does not enter the charging mode; and when the power supply component enters the charging mode and the power charging control and management B1021 detects that the power of the power supply component is saturated, the charging process will be terminated.

[0072] The embodiments of the present invention provide a charging control method. The above control method is applied to a power supply component separated from the terminal. According to the signal type and signal strength of the connection signal received by the power supply component, and based on a preset charging protocol, the specific charging mode is determined, so that the power supply component can flexibly select the charging method according to different usage scenarios, greatly improving the flexibility of charging.

[0073] It can be understood that in the embodiments of the present invention, the separated power supply component can adaptively adjust and select the charging scheme by detecting and identifying different signal types and signal strengths, and the first charging device corresponding to the embodiments of the present invention has a special placement area, so that the user does not need to adjust the alignment during charging; in addition, the power supply component can be charged separately and can independently achieve the first wireless fast charging or the second wireless fast charging, solving the problem of terminal heating. At the same time, it also meets the requirement of rapidity; and the terminal can also be designed to be made of metal, which does not affect the wireless charging effect and improves the user experience.

[0074] Embodiment 2

[0075] Based on the above Embodiment 1, exemplarily, the embodiments of the present invention use the connection methods characterized by different pins on the metal shrapnel interface B1 to illustrate the technical solutions of the above embodiments. Figure 6 Flow schematic of a charging control method proposed by the embodiments of the present invention Figure 1 , such as Figure 6 shown, the method includes:

[0076] S401. The power supply component detects the connection signal on the metal shrapnel interface B1.

[0077] In an embodiment of the present invention, the power supply component detects its current connection status through the connection signal on the metal shrapnel interface B1.

[0078] It should be noted that the connection signal on the metal shrapnel interface B1 consists of two parts, one is the connection indication on the power supply interface B1022, and the other is the signal strength indication on the detection control interface B1023.

[0079] S402. The power supply component determines whether the power supply component is connected to the terminal according to the connection signal, and executes step S403 or S404.

[0080] In an embodiment of the present invention, after the power supply component detects the connection signal, it can know whether it is connected to the terminal according to the connection signal. Specifically:

[0081] When there is a connection indication on the power supply interface B1022 of the power supply component, and there is no signal strength on the metal shrapnel pin corresponding to the first charging device on the detection control interface B1023, it is determined that the power supply component is connected to the terminal.

[0082] When there is no connection indication on the power supply interface B1022 of the power supply component, it is determined that the power supply component is not connected to the terminal.

[0083] S403. The power supply component is connected to the terminal, and the power supply component further determines whether the terminal is wired according to the connection signal, and executes step S403-1 or S403-2.

[0084] After the power supply component detects that it is connected to the terminal, it detects whether there is signal strength on the metal shrapnel pin corresponding to the terminal on the detection control interface B1023 to know whether it is wired after being connected to the terminal. If there is signal strength on the metal shrapnel pin corresponding to the terminal, step S403-1 is executed; otherwise, S403-2 is executed.

[0085] S403-1. A shrapnel voltage signal of a first preset intensity is used for wired small-current mode charging.

[0086] In an embodiment of the present invention, if there is a first preset intensity signal on the metal shrapnel pin corresponding to the terminal on the detection control interface B1023, the corresponding charging protocol is a wired slow charging protocol. At this time, the power charging control management B1021 in the power supply component controls the power supply component to perform wired small-current mode charging.

[0087] S403-2. An electromagnetic wave signal of a second preset intensity is used for wireless small-current mode charging.

[0088] If there is no signal strength on the metal spring pins corresponding to the terminal on the detection control interface B1023, and there is a first electromagnetic wave signal in the wireless charging receiving line module B1024 in the power supply component, the corresponding charging protocol is the wireless slow charging protocol. At this time, the power charging control management B1021 in the power supply component controls the power supply component to charge in the wireless small current mode.

[0089] It should be noted that the electromagnetic wave signal supports non-contact wireless charging within a short distance. In this step, the power supply component installed in the terminal body can be placed on the first charging device with a groove to achieve non-contact wireless small current charging, or the power supply component installed in the terminal body can be placed on the second charging device to achieve contactless wireless small current charging.

[0090] S404. The power supply component determines whether the received spring voltage signal on the metal spring pins corresponding to the first charging device is a second preset intensity, and executes step S405 or S406.

[0091] In the embodiment of the present invention, when there is a connection indication on the power interface B1022 of the power supply component, and when the power supply component detects that it is not connected to the terminal, it is necessary to determine the signal strength on the metal spring pins corresponding to the first charging device to confirm whether the power supply component is connected to the first charging device in a wired manner. If it is connected to the first charging device in a wired manner, step S405 is executed.

[0092] When there is no connection indication on the power interface B1022 of the power supply component and no signal strength on the metal spring pins corresponding to the first charging device, it indicates that the power supply component is not only not connected to the terminal but also not connected to the first charging device in a wired manner. At this time, the power supply component executes step S406.

[0093] S405. For the second preset intensity of the spring voltage signal, charge in the wired fast charging mode.

[0094] Specifically, when there is a connection indication on the power interface B1022 of the power supply component, and there is signal strength on the metal spring pins corresponding to the first charging device on the detection control interface B1023, and the signal strength of the spring voltage signal is the second preset intensity, the corresponding charging protocol is the wired fast charging protocol. At this time, the power supply component and the first charging device are connected in a wired manner, and the power charging control management B1021 in the power supply component controls the power supply component to charge in the wired fast charging mode.

[0095] S406. The power supply component determines whether the electromagnetic wave signal is a second electromagnetic wave signal, and executes step S407 or S408.

[0096] As described in step S404, at this time, the power supply component is not connected to the terminal, nor is it connected to the first charging device in a wired manner. Instead, it is connected to the first charging device or the second charging device in a wireless manner. At this time, it is necessary to determine the type of electromagnetic wave signal in the wireless charging receiving line module B1024 of the power supply component to determine whether the power supply component is specifically wirelessly connected to the first charging device or the second charging device.

[0097] S407. For the second electromagnetic wave signal, perform the first wireless fast charging mode for charging.

[0098] If the power supply component detects that it is the second electromagnetic wave signal, the power supply component is wirelessly connected to the first charging device. At this time, the corresponding preset charging protocol can be a standard wireless charging protocol, supporting 10-watt or 5-watt charging modes, or a private protocol customized by the user based on the wireless charging standard such as the wireless charging mode supporting 7.5 watts represented by Apple Inc.

[0099] S408. For the third electromagnetic wave signal, perform the second wireless fast charging mode for charging.

[0100] If the power supply component detects that it is the third electromagnetic wave signal, it means that the power supply component is connected to the second charging device in a wireless manner. At this time, the corresponding preset charging protocol is a general standard wireless charging protocol, supporting 10-watt or 5-watt wireless charging modes.

[0101] In this way, in the embodiment of the present invention, by the signal type and signal strength of the connection signal received by the power supply component, and based on the preset charging protocol, the specific charging mode is determined, so that the power supply component can flexibly select the charging method according to different usage scenarios.

[0102] Embodiment 3

[0103] Based on the same inventive concept of the above-mentioned Embodiment 1 and Embodiment 2, in this embodiment, the backup power supply component is used to increase the battery life of the terminal. Figure 7 The flowchart of a charging control method proposed by an embodiment of the present invention Figure 2 , as Figure 7 shown, the method includes:

[0104] S501. The power supply component detects its own power.

[0105] In the embodiment of the present invention, the power supply component is placed in the terminal to supply power to the terminal. The power charging control and management unit B1021 in the power supply component will monitor its own power and prompt the terminal.

[0106] S502. When the power is lower than the preset power, the terminal prompts the backup power supply component to charge.

[0107] When the terminal receives the current power information of the power supply component, if the power is lower than the preset power of the terminal, the terminal will prompt the user to back up the power supply component for charging.

[0108] S503. Charge the backup power supply component and monitor whether the power is saturated.

[0109] After receiving the prompt, the user places the backup power supply component in the first charging device or the second charging device for charging. During the charging process, the power charging control and management unit B1021 in the backup power supply component will monitor the charging process and determine whether the power is saturated.

[0110] Specifically, when the backup power supply component is placed in the first charging device for charging, the backup power supply component will detect the connection signal. When the connection signal is a shrapnel voltage signal and the signal strength is the second preset strength, the corresponding preset protocol is the wired fast charging protocol. At this time, the backup power supply component performs wired fast charging. When the backup power supply component receives the second electromagnetic wave signal, the corresponding preset charging protocol is the first wireless fast charging protocol. At this time, the backup power supply component performs the first wireless fast charging. When the backup power supply component is placed in the second charging device for charging and receives an electromagnetic wave signal, and it is the third electromagnetic wave signal, the corresponding preset charging protocol is the second wireless fast charging protocol. At this time, the backup power supply component performs the second wireless fast charging.

[0111] S504. If it is not saturated, continue charging until it is saturated.

[0112] When the power charging control and management unit B1021 monitors that the power is not saturated, it will continue charging until the power is saturated and stop charging. At the same time, the backup power supply component will immediately feedback the current power to the first charging device or the second charging device. Exemplarily, the current power status of the backup power supply component is displayed through different indicator light signals of C3 of the first charging device.

[0113] S505. The terminal displays an alarm message indicating that the power in the current power supply component is low.

[0114] In the embodiments of the present invention, when the terminal is powered by the power supply component, when the terminal receives that the power of the current power supply component is lower than the preset power threshold of the terminal, it will display an alarm message to the user so that the terminal user can replace the backup power supply component for power supply or supply power through the terminal and the power supply component together.

[0115] S506. The terminal user determines whether to replace it with the backup power supply component for power supply, and continues to execute step S507 or S508.

[0116] S507. The backup power supply component supplies power.

[0117] If the end user decides to use the fully charged backup power supply component, the terminal is powered by the backup power supply component.

[0118] Specifically, the user can install the backup power supply component in the corresponding groove of the terminal, and connect the metal shrapnel interface of the backup power supply component to the metal shrapnel interface of the terminal, so as to ensure that the backup power supply component is connected to the terminal in the correct way and realize the power supply to the terminal.

[0119] S508. The power supply component and the terminal perform wireless small current charging or wired small current charging integrally.

[0120] If the end user decides not to use the backup power supply component, the power supply component and the terminal perform charging integrally.

[0121] It can be understood that the embodiments of the present invention are based on a power supply component that can be separated from the terminal. When the power supply component detects that its own power is insufficient, it prompts the user to charge the backup power supply component, so as to increase the battery life of the terminal through the backup power supply component.
