当供电装置204和外部的充电装置均为目标硬件装置202供电时，智能终端可以选择较大的电压为目标硬件装置202供电。因此，相应的，电源调整装置201还包括：选择电路2013；选择电路2013的第一选择端(用C1表示)与电压转换电路102的输出端相连，选择电路2013的第二选择端(用C2表示)与供电装置204的电源正极相连，选择电路2013的输出端与目标硬件装置202的电源端相连。选择电路用于从第一选择端接收到的电压信号和第二选择端接收到的电压信号中，选择较大的电压信号为目标硬件装置202供电。When both the power supply device 204 and the external charging device supply power to the target hardware device 202 , the smart terminal can select a higher voltage to supply power to the target hardware device 202 . Therefore, correspondingly, the power adjustment device 201 further includes: a selection circuit 2013; the first selection end (indicated by C1) of the selection circuit 2013 is connected to the output end of the voltage conversion circuit 102, and the second selection end (indicated by C2) of the selection circuit 2013 ) is connected to the positive pole of the power supply device 204 , and the output terminal of the selection circuit 2013 is connected to the power supply terminal of the target hardware device 202 . The selection circuit is used to select a larger voltage signal from the voltage signal received by the first selection terminal and the voltage signal received by the second selection terminal to supply power to the target hardware device 202 .
由前述可知，电压转换电路2012转换得到的第二电压信号大于智能终端的系统电压，因此当供电装置204和外部的充电装置均为目标硬件装置202供电时，选择电路2013选择第一选择端接收到的电压信号为目标硬件装置供电，即此时是由外部的充电装置为目标硬件装置202供电以使得目标硬件装置202可以正常工作，满足用户需求。由此可见，目标硬件装置202工作过程中不会消耗供电装置204提供的系统电压，从而可以避免智能终端因系统电压被抽得很低而导致系统不稳定的情况，提高智能终端的系统稳定性以及安全性。It can be seen from the foregoing that the second voltage signal converted by the voltage conversion circuit 2012 is greater than the system voltage of the smart terminal, so when the power supply device 204 and the external charging device both supply power to the target hardware device 202, the selection circuit 2013 selects the first selection terminal to receive The received voltage signal supplies power to the target hardware device, that is, the external charging device supplies power to the target hardware device 202 so that the target hardware device 202 can work normally and meet user needs.

When the target hardware device is a high-power hardware device, if the target hardware device is used when the power of the smart terminal is lower than the preset power, the system voltage of the smart terminal will be drawn very low and the system will be unstable. Therefore, the embodiment of the present invention can send a trigger signal to the target hardware device 202 to trigger the target hardware device 202 to switch circuit 2011 sends a control signal, so that the switch circuit 2011 is turned on, so that the external charging device can supply power to the target hardware device 202 through the turned on switch circuit 2011 and the voltage conversion circuit 2012; to prevent the target hardware device 202 from consuming the system provided by the power supply device 204 Voltage, so as to avoid the system instability caused by the low system voltage of the smart terminal, and improve the system stability and security of the smart terminal.
在本发明实施例中，智能终端包括电源调整装置，该电源调整装置包括：开关电路和电压转换电路；开关电路的第一端用于与外部的充电装置的电源正极相连，开关电路的第二端与目标硬件装置的信号端相连，开关电路的第三端与电压转换电路的输入端相连，电压转换电路的输出端与目标硬件装置的电源端相连。本发明实施例的智能终端可以根据目标硬件装置发送的控制信号导通开关电路，使得外部的充电装置通过导通的开关电路和电压转换电路为目标硬件装置供电，满足用户的需求。In the embodiment of the present invention, the smart terminal includes a power adjustment device, and the power adjustment device includes: a switch circuit and a voltage conversion circuit; the first end of the switch circuit is used to connect to the positive pole of the power supply of the external charging device, and the second end of the switch circuit The terminal is connected to the signal terminal of the target hardware device, the third terminal of the switch circuit is connected to the input terminal of the voltage conversion circuit, and the output terminal of the voltage conversion circuit is connected to the power supply terminal of the target hardware device.

基于上述实施例的描述，本发明实施例还提供一种如图4所示的电源调整方法，该电源调整方法应用于上述实施例所提及的智能终端，该电源调整方法包括：Based on the description of the above embodiment, the embodiment of the present invention also provides a power adjustment method as shown in FIG. 4, the power adjustment method is applied to the smart terminal mentioned in the above embodiment, and the power adjustment method includes:
S401，当检测到智能终端与外部的充电装置相连，且目标应用所对应的目标硬件装置的功率大于预设功率时，发送触发信号至目标硬件装置，以触发目标硬件装置向开关电路发送控制信号。S401, when it is detected that the smart terminal is connected to an external charging device, and the power of the target hardware device corresponding to the target application is greater than the preset power, send a trigger signal to the target hardware device to trigger the target hardware device to send a control signal to the switch circuit .
在检测到用户打开目标应用的打开操作时，可以确定目标应用所对应的目标硬件装置的功率是否大于预设功率。若大于，则检测智能终端与外部的充电装置是否相连。若相连，则可以发送触发信号至目标硬件装置，以触发目标硬件装置向开关电路发送控制信号。When an opening operation of opening the target application by the user is detected, it may be determined whether the power of the target hardware device corresponding to the target application is greater than a preset power. If it is greater than, then detect whether the smart terminal is connected to an external charging device. If connected, a trigger signal can be sent to the target hardware device to trigger the target hardware device to send a control signal to the switch circuit.
其中，此处的目标应用是指消耗的电量大于预设电量的应用，该目标应用可以包括但不限于：闪关灯应用。预设功率的取值可以根据经验值或者业务需求设置。Wherein, the target application here refers to an application that consumes more power than a preset power, and the target application may include but not limited to: a flashing light application. The value of the preset power can be set according to experience value or business requirement.
在一种实施方式中，在发送触发信号至目标硬件装置之前，还可以：检测智能终端的电量是否低于预设电量；若智能终端的电量低于预设电量，则触发执行发送触发信号至目标硬件装置的步骤。In one embodiment, before sending the trigger signal to the target hardware device, it is also possible to: detect whether the power of the smart terminal is lower than the preset power; if the power of the smart terminal is lower than the preset power, trigger the execution of sending the trigger signal to Steps for the target hardware device.
由于目标硬件装置大于预设功率，即目标硬件装置为大功率的硬件装置，若在智能终端的电量低于预设电量时使用该目标硬件装置，则会导致智能终端的系统电压被抽得很低导致系统不稳定。因此，本发明实施例在检测到智能终端的电量低于预设电量时，可以发送一个触发信号给目标硬件装置，以触发目标硬件装置向开关电路发送控制信号，使得开关电路导通，从而使得外部的充电装置可以通过导通的开关电路和电压转换电路为目标硬件装置供电。避免目标硬件装置消耗供电装置提供的系统电压，从而可以避免智能终端因系统电压被抽得很低而导致系统不稳定的情况，提高智能终端的系统稳定性以及安全性。Since the target hardware device is greater than the preset power, that is, the target hardware device is a high-power hardware device, if the target hardware device is used when the power of the smart terminal is lower than the preset power, the system voltage of the smart terminal will be drawn very much. Low leads to system instability. Therefore, in the embodiment of the present invention, when it is detected that the power of the smart terminal is lower than the preset power, a trigger signal can be sent to the target hardware device, so as to trigger the target hardware device to send a control signal to the switch circuit, so that the switch circuit is turned on, so that The external charging device can supply power to the target hardware device through the conducting switch circuit and the voltage conversion circuit. The target hardware device is prevented from consuming the system voltage provided by the power supply device, thereby avoiding system instability caused by the low system voltage of the smart terminal, and improving the system stability and security of the smart terminal.
