The technical solution of the present application is further elaborated below with reference to the drawings and the specific embodiments.
Example one
The present embodiment provides an electronic device, as shown in fig. 1, the electronic device includes a power inlet 10, a first interface 20, a function device 30, a detection device 40, and a processing device 50; wherein the content of the first and second substances,
the power supply inlet 10 is used for obtaining power supply;
the first interface 20 is capable of connecting a first powered device;
the functional device 30, the functional device 30 having at least two operating states, wherein the operating power of the functional device 30 is different in the different operating states;
the detection device 40 is disposed between the functional device 30 and the power inlet 10, and is configured to determine a current power parameter representing an operating state or an operating power of the functional device 30;
the processing device 50 is connected to the detecting device 40 and the first interface 20, and configured to determine a transferable power parameter at least according to the current power parameter and the design power parameter; determining an adjusted power output information according to the transferable power parameter and the original power parameter, and transmitting the adjusted power output information to the first powered device through the first interface 20 for the first powered device to adjust a powered mode based on the adjusted power output information,
wherein the design power is the maximum power that can be provided to the functional device 30; the raw power is a default power provided by the electronic device for the first powered device.
In this embodiment, in the above-mentioned current power parameters characterizing the operating state or the operating power of the functional device 30, the current power parameters of the operating state or the operating power specifically refer to: a current power parameter indicative of an operating state, or a current power parameter indicative of an operating power.
Here, the operation state includes at least one of:
an on state or an off state;
the working state of the functional device 30 corresponding to the target parameter value in the on state; in the on state, when the target parameter of the function device 30 is different, the operating power is different.
In this embodiment, the functional devices 30 are divided into at least two types:
the first type of functional device only has an on state and an off state;
the second kind of functional device not only has an on state and an off state, but also has different working states corresponding to different target parameter values in the on state.
That is, in the on state, when the target parameter of the functional device has different values, the operating power thereof is different.
For example, the first type of functional device may be a component built in an electronic device, such as a camera, or may be a device connected to the electronic device, such as a keyboard, a mouse, a mobile hard disk, or the like; the second functional device may be a component built in the electronic device, such as a backlight panel, a speaker, etc.
In some alternative embodiments, the detection device 40 is specifically configured to determine a current power parameter that characterizes an operating state of the functional device 30.
Taking the function device 30 as a first type function device as an example, when the working state of the first type function device is the off state, the current power parameter of the off state is 0; and when the working state of the first type of functional device is the opening state, the current power parameter of the opening state is a preset value.

For example, when the first type of functional device is m, the current power parameter of the on state is m 1; when the first type of function device is n, the current power parameter in the on state is n 1.
In some alternative embodiments, the detection device 40 is specifically configured to determine a current power parameter that characterizes an operating power of the functional device 30.

In this embodiment, the adjusted power output information includes at least one set of combined voltage and current data. The full power output information is power output information which can be supported by a first interface of the electronic equipment.
In this embodiment, the adjusted power output information is determined according to the transferable power parameter and the original power parameter, because the original power is the default power, no matter the first powered device has just connected to the electronic device, that is, the first powered device has not adjusted the power receiving mode, or the first powered device has connected to the electronic device for a period of time, if the first powered device has adjusted the power receiving mode once or multiple times, the electronic device does not need to consider the magnitude of the adjusted power receiving power of the first powered device each time the electronic device determines to adjust the power output information, and only needs to determine based on the original power parameter as a reference, which is simple in calculation and short in time consumption.
In the electronic device of this embodiment, since the function device 30 has at least two working states, the working powers of the function device 30 are different in different working states, the electronic device determines the current power parameter representing the working state or the working power of the function device 30 through the detection device 40, and determines the adjustment power output information that can be selected by the power receiving device according to the transferable power and the original power through the processing device 50, so that the transferable power of the function device 30 can be fully considered, and the effect of increasing the maximum power output by the power output interface of the electronic device can be achieved without increasing the overall design power consumption of the electronic device; because the power output interface can provide the output power which is larger than the original power for the powered device, the fully charged speed of the powered device is faster, and the use experience of a user is improved.

the power supply inlet 10 is used for obtaining power supply;
the first interface 20 is capable of connecting a first powered device;
the functional device 30, the functional device 30 having at least two operating states, wherein the operating power of the functional device 30 is different in the different operating states; the functional apparatus 30 includes the second interface 301, to which a second powered device can be connected, and an operating state of the second interface is related to an operating state of the second powered device connected thereto;
the detection device 40 is disposed between the functional device 30 and the power inlet 10, and is configured to determine a current power parameter representing an operating state or an operating power of the functional device 30;

wherein the design power is the maximum power that can be provided to the functional device 30; the raw power is a default power provided by the electronic device for the first powered device.
In the above solution, the first interface 20 is configured to supply power to the first powered device, and is further configured to obtain or send first data of the first powered device.
Here, the first power receiving apparatus is an apparatus that can be connected to an electronic apparatus via a first interface and can obtain power from the electronic apparatus. For example, the first powered device is a mobile phone, a notebook computer, a tablet computer, or the like.
Optionally, the first interface 20 is an interface supporting power output and data transmission, for example, the first interface is USB Type-C (USB-C for short).
In the above solution, the second interface 301 is configured to supply power to a second powered device, and is further configured to obtain or send second data of the second powered device; the working state of the second interface only has two states of opening and closing.
That is, the working state of the second interface changes along with the change of the state of the second external device connected with the second interface.
Optionally, the second interface 301 is an interface supporting power output and data transmission, for example, the second interface is USB Type-a (USB-a for short).

It should be noted that, the USB-a device may be detected by the USB hub, and the maximum power output by the USB-C may be increased by controlling the number of the USB-a devices connected, but since the USB hub cannot identify some USB-a devices without D +/D, such as a USB small fan, a USB small desk lamp, etc., a certain power may need to be reserved for such USB-a devices. Clearly, increasing the maximum power supply power of the USB-C output in this way has a limited effect.
In this embodiment, the detection device 40 can determine the current power parameter representing the working state or working power of the function device 30, that is, can identify all devices connected to the second interface 301, and can identify not only USB-a devices with D +/D, such as a keyboard, a mouse, a memory, etc., but also USB-a devices without D +/D, such as a USB small fan, a USB small desk lamp, etc., compared with the existing control scheme that can only identify USB-a devices with D +/D, because the identification range is wide, it is not necessary for the electronic device to reserve a certain power for the USB-a devices without D +/D, and it is really realized how much electricity is subtracted by how much electricity, and the maximum power output by the USB-C can be increased to the maximum extent.
In this embodiment, the electronic device determines the current power parameter representing the working state of the second interface 301 through the detection device 40, and determines the adjustment power output information that can be selected by the powered device according to the transferable power and the original power through the processing device 50, so that the transferable power of the second interface 301 can be fully considered, and the effect of increasing the maximum power output by the power output interface of the electronic device can be achieved without increasing the overall design power consumption of the electronic device; because the power output interface can provide the output power which is larger than the original power for the powered device, the fully charged speed of the powered device is faster, and the use experience of a user is improved.

Example four
The embodiment provides an electronic device, which comprises a power inlet 10, a first interface 20, a function device 30, a detection device 40 and a processing device 50; wherein the content of the first and second substances,
the power supply inlet 10 is used for obtaining power supply;
the first interface 20 is capable of connecting a first powered device;
the functional device 30, the functional device 30 having at least two operating states, wherein the operating power of the functional device 30 is different in the different operating states;
the detection device 40 is disposed between the functional device 30 and the power inlet 10, and is configured to determine a current power parameter representing an operating state or an operating power of the functional device 30;
the processing device 50 is connected to the detecting device 40 and the first interface 20, and configured to determine a transferable power parameter at least according to the current power parameter and the design power parameter; determining an adjusted power output information according to the transferable power parameter and the original power parameter, and transmitting the adjusted power output information to the first powered device through the first interface 20 for the first powered device to adjust a powered mode based on the adjusted power output information,
wherein the design power is the maximum power that can be provided to the functional device 30; the raw power is a default power provided by the electronic device for the first powered device.
In the foregoing scheme, optionally, the processing device 50 is specifically configured to:
determining a transferable power parameter from the current power parameter and the design power parameter according to a priority relationship of the first powered device to the functional apparatus 30.
In this way, the transferable power can be determined in combination with the actual conditions of the first powered device and the functional apparatus to meet the needs of at least one of them.
In the foregoing scheme, optionally, the processing device 50 is further specifically configured to:
when the priority of the first powered device is lower than the priority of the function device 30, a difference between the design power parameter and the current power parameter is determined as a transferable power parameter.
In this way, when the priority of the first powered device is lower than the priority of the functional device 30, the transferable power parameter is determined on the basis of the power requirement of the functional device 30 being satisfied, taking into full account the power requirement of the functional device 30 being satisfied.
For example, if the priority of the first powered device is lower than that of the functional device 30, and it is detected that the current power parameter corresponding to the current operating state of the functional device 30 is P1 and the design power of the functional device 30 is P0, the transferable power parameters are determined as P0-P1.
In the foregoing scheme, optionally, the processing device 50 is further specifically configured to:

In some optional embodiments, the processing device 50 is further specifically configured to:
if the desired transferable power range exceeds the transferable power of the functional device 30, the desired transferable power range is satisfied by shutting down or adjusting the operating state of the functional device 30.

That is, the electronic device may currently provide the power for the first powered device as [ P2+0, P2+ (P0-P1) ], and if the desired power range of the first powered device is [ P3, P4], when [ P3, P4] exceeds the interval range of [ P2+0, P2+ P0-P1], directly determine the power corresponding to the adjusted power output information provided for the first powered device as [ P3, P4], and close or adjust the operating state of the function apparatus 30 to meet the requirement of the desired power range of the first powered device.
