Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe various operations (or steps) as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously.

Embodiment one

Figure 1 shows the flow chart of the terminal charging method provided by Embodiment 1 of the present invention. The method of this embodiment can be executed by a terminal charging device, which can be implemented by means of hardware and/or software. The device Can be arranged inside the terminal as a part of the terminal.

As shown in FIG. 1, the terminal charging method provided in this embodiment specifically includes the following steps:

Step 101, after the terminal is connected to the USB interface of the computer through the data cable, the interface type of the USB interface input by the user is obtained.

The terminals described in this embodiment include but are not limited to mobile phones, tablet computers, notebooks, cameras and other electronic devices.

Wherein, the method of obtaining the interface type of the USB interface input by the user may be to pop up an interface type selection window on the user interface of the terminal, and obtain the interface type of the USB interface selected by the user, or obtain the user's The interface type of the USB interface input on the user interface of the terminal may also be in another manner capable of obtaining the interface type of the USB interface input by the user, which is not limited in this embodiment.

Step 102: Determine the charging mode of the terminal according to the interface type of the USB interface, and instruct the computer to charge the terminal in the charging mode.

This step determines the charging mode of the terminal according to the interface type of the USB interface, instead of simply determining the charging mode of the terminal as a charging mode with a small charging current, it can be adaptively determined according to the interface type of the USB interface. Adjust the charging method of the terminal. For example, when the interface type of the USB interface is USB3.0, the charging mode of the terminal may be determined as a charging mode matching the charging current provided by the USB3.0 interface, and the interface type of the USB interface is USB2.0. 0 or cannot be determined, determine that the charging mode of the terminal is a charging mode that matches the charging current provided by the USB2.0 interface, instead of always determining the charging mode of the terminal as the charging mode corresponding to the USB2.0 interface in the prior art, It can effectively use the current provided by the USB interface of the computer.

Wherein, instructing the computer to charge the terminal with the charging method described in this step specifically includes: the terminal sends a charging method control instruction corresponding to the charging method to the computer, so as to instruct the computer to input to the terminal through the USB interface The corresponding ladder-type current in the charging mode, the ladder-type current is a current whose current value increases sequentially; receiving the ladder-type current input by the computer through the USB interface to charge the terminal.

The method for charging the terminal provided in this embodiment is a technical means for adaptively adjusting the charging mode of the terminal according to the interface type of the USB interface of the computer connected to the terminal when the terminal is charged by the computer, which solves the problem that is always present in the prior art. According to the technical problem of not being able to effectively use the higher current that the computer can provide due to the charging method with a small charging current, the charging method of the terminal through the computer is optimized.

Embodiment two

FIG. 2 shows a flowchart of a method for charging a terminal provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the foregoing embodiments. In this embodiment, the charging mode of the terminal will be determined according to the interface type of the USB interface, specifically optimized as follows: when the interface type of the USB interface is a preset type, determine that the charging mode of the terminal is the first charging mode , otherwise, determine that the charging mode of the terminal is the second charging mode.

Further, when the interface type of the USB interface is a preset type, determining that the charging mode of the terminal is the first charging mode is further optimized as: when the interface type of the USB interface is a preset type, judging that the Whether the loading capacity of the USB interface meets the first preset threshold; when the loading capacity of the USB interface meets the first preset threshold, determine that the charging mode of the terminal is the first charging mode.

Correspondingly, the terminal charging method provided in this embodiment specifically includes the following steps:

Step 201, after the terminal is connected to the USB interface of the computer through the data cable, the interface type of the USB interface input by the user is acquired.

Step 202, judging whether the interface type of the USB interface is a preset type.

When the interface type of the USB interface is a preset type, step 203 is performed; otherwise, step 205 is performed.

Step 203, judging whether the carrying capacity of the USB interface meets a first preset threshold.

When the carrying capacity of the USB interface meets the first preset threshold, step 204 is performed; otherwise, step 205 is performed.

The function of this step is to judge whether the real carrying capacity of the USB interface satisfies the first preset threshold. Because, in actual use, when the interface type of the USB interface is a preset type, the current (load capacity) that the USB interface can provide may not necessarily reach the load capacity marked by the preset type, for example, The load capacity marked on the USB3.0 interface type is 1A, but the actual maximum current that can be provided may be 800mA. Therefore, when the interface type of the USB interface is a preset type, it is judged whether the carrying capacity of the USB interface meets the first preset threshold, and when the first preset threshold is met, it is considered that the charging method corresponding to the USB interface can It is the charging method corresponding to the preset type. For example, if the preset type is USB3.0, and the first preset threshold value is 700 mA, then when the carrying capacity of the USB interface reaches 700 mA, it is considered that the charging method corresponding to the USB interface can It is the first charging method corresponding to the USB3.0 interface type.

When the interface type of the USB interface is a preset type, judging whether the loading capacity of the USB interface meets the first preset threshold specifically includes: when the interface type of the USB interface is a preset type, the receiving computer passes The ladder-type current input by the USB interface, the ladder-type current is a current whose current value increases sequentially; the voltage value of the charging circuit of the terminal is obtained regularly; if the voltage value is less than the second preset threshold value, the previous ladder current The value is used as the loading capacity of the USB interface; if the voltage value is greater than the second preset threshold, and the current ladder current value reaches the preset loading capacity corresponding to the USB interface, then the preset loading capacity is used as the USB The carrying capacity of the interface: judging whether the carrying capacity of the USB interface meets a first preset threshold.

According to the prior art, it can be understood that when the computer is charging the terminal, the voltage value of the charging circuit in the terminal will gradually decrease until it reaches the second preset threshold. A voltage of 5V, the second preset threshold may be 4.6V, and when the voltage of the charging circuit is between 5V and 4.6V, the computer inputs a ladder current to the terminal.

If the voltage value is less than the second preset threshold value, the last step current value is used as the loading capacity of the USB interface. For example, when the voltage value of the charging circuit of the terminal is detected to be 4.7V at the first moment, the computer inputs to the terminal The stepped current value of the terminal is 700 mA, and the voltage value of the charging circuit of the terminal is detected to be 4.5V at the next moment, which is less than the second preset threshold value of 4.6V, and the stepped current value detected at the previous moment is 700 mA. As the carrying capacity of the USB interface.

If the voltage value is greater than the second preset threshold and the current step current value has not yet reached the preset load capacity corresponding to the USB interface, the terminal continues to receive the step current input by the computer. Wherein, the preset loading capacity may be the loading capacity marked on the interface type of the USB interface.

Further, the method further includes the following step: if the carrying capacity of the USB interface is less than the third threshold, turning off the charging function. The reason for this setting is to ensure that when the loading capacity of the USB interface of the computer is less than the third threshold, for example, when the power of the computer is low or the computer fails, the charging function is turned off to protect the computer and the terminal.

Wherein, the third threshold may be the minimum current value in the ladder current, of course, this value may be set according to specific needs, which is not limited in this embodiment.

Step 204, determine that the charging mode of the terminal is the first charging mode, and instruct the computer to charge the terminal in the first charging mode.

This step may specifically include: the terminal sends a first charging mode control instruction to the computer to instruct the computer to input a ladder current from the fourth preset threshold value to the carrying capacity value of the USB interface to the terminal through the USB interface; receiving The computer charges the terminal through the stepped current input by the USB interface from the fourth preset threshold value to the carrying capacity value of the USB interface.

For example, if the step current is 100 mA to 1 A with an interval of 100 mA, the fourth preset threshold may be 500 mA, and the carrying capacity value of the USB interface may be 1 A, Then the terminal instructs the computer to input a stepped current from 500mA to 1A to the terminal through the USB interface.

The advantage of such a setting is: input a ladder-type current from the fourth preset threshold value to the carrying capacity value of the USB interface to the terminal, instead of starting from the current of the minimum value of the ladder-type current (for example, 100 milliamperes), Under the premise of satisfying safe charging, the charging speed of the terminal can be accelerated.

Step 205, determine that the charging mode of the terminal is the second charging mode, and instruct the computer to charge the terminal in the second charging mode.

When the first charging method is a charging method corresponding to a USB3.0 interface type, the second charging method may be a charging method corresponding to a USB2.0 interface type.

In the terminal charging method provided in this embodiment, when the computer charges the terminal, it is judged whether the interface type of the USB interface of the computer connected to the terminal is a preset type, and when the interface type of the USB interface is a preset type, , determine that the charging method of the terminal is the first charging method, and instruct the computer to charge the terminal in the first charging method, otherwise, determine that the charging method of the terminal is the second charging method, and instruct the computer to charge the terminal in the second charging method To charge the terminal, by adaptively adjusting the charging mode of the terminal, the current that can be provided by the USB interface of the connected computer can be effectively used to speed up the charging speed of the terminal and reduce the charging time of the terminal.
