Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In this application, "at least one" means one or more, and "multiple" means two or more.

In addition, in order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish the same or similar items with basically the same function and effect, Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order. For example, "first" in the first wired charging circuit and "second" in the second wired charging circuit in the embodiment of the present application are only used to distinguish different wired charging circuits. The first, second, etc. descriptions that appear in the embodiments of this application are only for illustration and to distinguish the description objects. Any limitations of the examples.

It should be noted that, in this application, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design described herein as "exemplary" or "for example" is not to be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

When the electronic device is in the bright screen state, if the electronic device is charged by wire, due to the increase in the overall temperature rise of the electronic device, the charging speed of the electronic device will be limited, resulting in a slower charging speed in the scene where the electronic device is bright.

FIG. 1 is a schematic structural diagram of an electronic device. As shown in Figure 1, when an electronic device is charged by wire, the current flows from the power adapter into the charging flexible circuit board (flexible printed circuit board, FPC) in the electronic device, and then passes through two switched capacitor (SC) charging chips. After converting the voltage of about 10V to about 5V, it supplies power to the battery of the electronic device. When the electronic device is wirelessly charged, the coil in the wireless charger and the wireless charging coil in the electronic device have electromagnetic induction, and the induced current is rectified by the rectifier circuit, and then charged to the chip by a high voltage switched capacitor (HVSC) Convert the voltage of about 20V to about 10V, and then convert the voltage of about 10V to about 5V through two SC charging chips, and then supply power to the battery of the electronic device.

Optionally, the embodiment of the present application does not limit the number of SC charging chips in the electronic device. FIG. 1 illustrates an example in which the electronic device includes two SC charging chips (SC1 and SC2). In practical applications, the number of SC charging chips depends on how many pairs of connectors the battery of the electronic device has. For example, the electronic device may also include one SC charging chip.

As shown in Figure 1, when the user is charging while watching a video, or the user is charging while playing a game, or the user is charging while shopping online, etc., since the screen of the electronic device is in the bright state, the electronic device Chips in the motherboard (for example, a system on chip (SoC), which may include SC1 and SC2 shown in Figure 1) will generate heat, and if the electronic device is charged by wire while the screen is on, the two Both the SC chip and the charging FPC will generate heat, which will lead to a higher temperature on the motherboard of the electronic device and affect the charging speed of the bright screen.

Exemplarily, by reducing channel impedance or increasing heat dissipation measures, the heating of electronic devices in bright screen scenes can be reduced, and the charging speed of bright screens can be increased. For example, the path impedance can be reduced by increasing the thickness of the charging FPC, and heat dissipation can also be achieved by increasing the vacuum chamber (vapor chambers, VC) and graphite. However, increasing the thickness of the charging FPC, as well as increasing the VC and graphite, will increase the thickness of the electronic device and increase the cost.

In order to increase the charging speed of electronic devices, especially the charging speed of electronic devices with the screen on, an embodiment of the present application provides an electronic device, which can increase the charging speed of electronic devices when the electronic device is charged by wire, especially in electronic devices. In the scene of bright screen charging, the speed of bright screen charging can be significantly improved. Moreover, the embodiment of the present application may not change the size of the electronic device, and may even reduce the size of the electronic device when increasing the charging speed of the electronic device when the screen is turned on.

The electronic device provided in the embodiment of the present application can increase the charging speed when the electronic device is charging with the screen on, and can also increase the charging speed when the electronic device is charging with the screen off. The embodiment of the present application does not limit the specific scenario of charging the electronic device with the screen turned on. For example, scenarios of charging an electronic device with the screen on include, but are not limited to, charging while watching a video, charging while playing a game, charging while shopping online, and so on. The screen-on charging scene in the embodiments of the present application is applicable to any scene in which the electronic device is charged while the screen of the electronic device is in a bright-screen state.

The embodiments of the present application are applied to electronic devices including wireless charging coils. As shown in FIG. 2 , the electronic device includes a wireless charging coil, which may be a multi-turn coil.

Optionally, the wireless charging coil in the electronic device may be a single-layer coil, or may include multi-layer coils in a direction perpendicular to the screen of the electronic device, and each layer of coil is a multi-turn coil. The number of layers and the number of turns of the wireless charging coil are not limited.

An embodiment of the present application provides an electronic device, the electronic device includes a wireless charging circuit and a wired charging circuit, the wireless charging circuit includes a wireless charging coil, and the wired charging circuit includes a first wired charging circuit, wherein the first wired charging circuit and the wireless charging circuit Corresponding setting of the coil.

When the electronic device is charged wirelessly, the electronic device is charged through the wireless charging circuit. When the electronic equipment is charged by wire, the electronic equipment is charged through the wired charging circuit.

The wired charging circuit in the embodiment of the present application may include a variety of different circuit structures. Under different circuit structures of the wired charging circuit, the first wired charging circuit may or may not multiplex the wireless charging coil. The process of performing wired charging and wireless charging on electronic devices and the specific form of the first wired charging circuit will be described in detail below in combination with four different circuit structures of the wired charging circuit.

The first circuit structure: as shown in FIG. 3 , the wired charging circuit further includes a first voltage conversion circuit connected in series with the first wired charging circuit. The first end of the first wired charging circuit is used to be coupled to the power adapter through the first voltage conversion circuit, and the second end of the first wired charging circuit is coupled to the battery of the electronic device.

Optionally, the wireless charging circuit may further include a rectification circuit, an HVSC and a second voltage conversion circuit. The input end of the rectification circuit is coupled to the wireless charging coil, the output end of the rectification circuit is coupled to the input end of the HVSC, the output end of the HVSC is coupled to the input end of the second voltage conversion circuit, and the output end of the second voltage conversion circuit is connected to the electronic device The battery coupling connection. The embodiment of the present application does not limit the number of the second voltage conversion circuits, and the number of the second voltage conversion circuits depends on how many pairs of connectors the battery of the electronic device has. FIG. 3 , FIG. 5 , FIG. 7 and FIG. 9 in the embodiment of the present application illustrate with one second voltage conversion circuit as an example. In practical applications, there may also be two second voltage conversion circuits in an electronic device.

Fig. 4 is a schematic structural diagram of charging of an electronic device. In conjunction with FIG. 3, as shown in FIG. 4, when the electronic device is charged by wire, the current output by the power adapter passes through the first voltage conversion circuit in the electronic device, and then supplies power to the battery of the electronic device through the first wired charging circuit. When electronic equipment is wirelessly charged, electromagnetic induction occurs between the coil in the wireless charger and the wireless charging coil in the electronic equipment. After the induced current is rectified by the rectifier circuit, the voltage of about 20V is converted into a voltage of about 10V by the HVSC chip. After the voltage of about 10V is converted into a voltage of about 5V by the second voltage conversion circuit, power is supplied to the battery of the electronic device.

Optionally, when the electronic device is charged by wire, the output voltage of the power adapter may be about 10V or about 5V. When the output voltage of the power adapter is about 10V, the first voltage conversion circuit is used to convert the voltage of about 10V into a voltage of about 5V. That is, the first voltage converting circuit is in a step-down mode. When the output voltage of the power adapter is about 5V, the first voltage conversion circuit is used to directly output the voltage of about 5V. That is, the output voltage of the first voltage conversion circuit is the same as the input voltage, and the first voltage conversion circuit is in a direct mode. It can be understood that the step-down mode and the direct mode of the first voltage conversion circuit can be realized by controlling the on and off of the switches in the first voltage conversion circuit. The direct mode of the first voltage conversion circuit generates less heat than the step-down mode.

For example, as shown in FIG. 3 and FIG. 4, in the scene of charging the electronic device with the screen on, the output voltage of the power adapter can be about 5V, and the first voltage conversion circuit is controlled to be in the direct mode, so that the output voltage of the first voltage conversion circuit It is the same as the input voltage, and after the voltage of about 5V output by the first voltage conversion circuit is transmitted through the first wired charging line, it charges the battery of the electronic device. Since the through mode of the first voltage conversion circuit generates less heat than the step-down mode, in the bright screen charging scenario, by setting the output voltage of the power adapter to about 5V, the first voltage conversion circuit is controlled to be in the through mode, The charging speed of bright screen charging can be further improved.

For another example, as shown in FIG. 3 and FIG. 4 , in the scene where the screen of the electronic device is off and charging, the output voltage of the power adapter can be about 10V, and the first voltage conversion circuit is controlled to be in step-down mode, so that the first voltage conversion circuit The output voltage is lower than the input voltage, and the voltage of about 5V output by the first voltage conversion circuit is transmitted through the first wired charging line to charge the battery of the electronic device.

The embodiment of the present application does not limit the output voltage of the power adapter when the electronic device is charged with the screen on or off, and the above is only an exemplary description. For example, in the scene of charging an electronic device with the screen on, the output voltage of the power adapter can also be about 10V, and the first voltage conversion circuit is controlled to be in step-down mode, so that the output voltage of the first voltage conversion circuit is lower than the input voltage, and the second A voltage of about 5V output by the voltage conversion circuit is transmitted through the first wired charging line, and then charged to the battery of the electronic device. That is, when the electronic device is charged by wire, it is also possible not to distinguish between the charging scene with the screen on and the charging scene with the screen off, and the output voltage of the power adapter is the same.

The corresponding setting of the first wired charging circuit and the wireless charging coil may include: the first wired charging circuit multiplexes the wireless charging coil, or the first wired charging circuit does not multiplex the wireless charging coil.

When the first wired charging circuit multiplexes the wireless charging coil, the above-mentioned corresponding setting of the first wired charging circuit and the wireless charging coil may include the following three implementations.

In a first implementation manner, the first wired charging circuit is provided correspondingly to the wireless charging coil, including: the first wired charging circuit is at least a part of the wireless charging coil.

When the first wired charging circuit is at least a part of the wireless charging coil, the first wired charging circuit multiplexes at least a part of the wireless charging coil.

When the first wired charging line does not reuse the wireless charging coil, the first wired charging line and the wireless charging coil are independent of each other, and the first wired charging line can be arranged around the wireless charging coil along the outline of the wireless charging coil. The number of the first wired charging circuit arranged along the outline of the wireless charging coil may be one or multiple, which is not limited in this embodiment of the present application. When there are multiple first wired charging lines, the multiple first wired charging lines are connected in parallel.

For example, as shown in (c) in FIG. 3 , the first wired charging circuit is not electrically connected to the wireless charging coil, and the first wired charging coil is provided with a half-turn coil around the wireless charging coil along the outline of the wireless charging coil. There is one first wired charging line, the first end of the first wired charging line is used to couple with the power adapter through the first voltage conversion circuit, and the second end of the first wired charging line is coupled to the battery of the electronic device .

For example, taking the wireless charging coil in an electronic device including a 10-turn coil as an example, when the first wired charging circuit is not electrically connected to the wireless charging coil, another turn of the coil can be arranged around the wireless charging coil along the outline of the wireless charging coil , the one-turn coil is a first wired charging circuit for wired charging.

Optionally, when the first wired charging does not reuse the wireless charging coil, the material of the first wired charging circuit and the wireless charging coil can be the same.

It can be understood that, compared with the electronic device shown in FIG. 1, the electronic device shown in FIG. 3 can make the first wired charging circuit larger or wider by omitting the charging FPC in the electronic device, which can reduce the charging time. The path impedance of the small wired charging circuit improves the charging speed of electronic devices with bright screens. Moreover, when the electronic device of this embodiment is charged by wire, the charging current can directly flow into the battery of the electronic device from the port of the first wired charging line, and the charging current can not pass through the second voltage conversion circuit in the main board, so the voltage on the main board can be reduced.

The electronic device shown in FIG. 3 can significantly increase the speed of charging when the screen is on, especially in the scene of charging the electronic device with the screen on. In addition, in this embodiment, when the first wired charging circuit multiplexes the wireless charging coil, by setting the first switch and the second switch, it is possible to prevent the voltage generated on the wireless charging coil from affecting the wired charging circuit during wireless charging of the electronic device.

When there are multiple second voltage conversion circuits, the multiple second voltage conversion circuits are connected in parallel, the first end of the second wired charging circuit is coupled to the input end of the first voltage conversion circuit, and the second wired charging circuit The second terminals are respectively coupled and connected to the battery of the electronic device through the plurality of second voltage conversion circuits. FIG. 5 shows an example by taking the second voltage conversion circuit as an example.

Fig. 6 is a structural diagram of a charging principle of an electronic device. Referring to FIG. 5, as shown in FIG. 6, when the electronic device is charged by wire, one current of the power adapter passes through the first voltage conversion circuit in the electronic device, and then supplies power to the battery of the electronic device through the first wired charging circuit. The other current of the power adapter passes through the second wired charging circuit in the electronic device, and then passes through the second voltage conversion circuit to supply power to the battery of the electronic device. When electronic equipment is wirelessly charged, electromagnetic induction occurs between the coil in the wireless charger and the wireless charging coil in the electronic equipment. After the induced current is rectified by the rectifier circuit, the voltage of about 20V is converted into a voltage of about 10V by the HVSC chip. After the voltage of about 10V is converted into a voltage of about 5V by the second voltage conversion circuit, power is supplied to the battery of the electronic device. That is, when the electronic device is charged by wire, the battery of the electronic device is jointly charged through the first wired charging circuit and the second wired charging circuit.

Optionally, the second wired charging circuit in the embodiment of the present application may be the charging FPC shown in FIG. 1 .

In this embodiment, when the electronic device is charged by wire, the first wired charging circuit and the second wired charging circuit jointly charge the battery, so that the heat generation of the electronic device can be dispersed. Moreover, the two wired charging lines are used to charge the battery together, which can reduce the channel impedance and increase the charging speed of electronic devices in the scene of bright screen charging, especially in the scene of bright screen charging of electronic devices, it can significantly improve the brightness of the screen. The speed of charging.

Optionally, when the electronic device is charged by wire, the output voltage of the power adapter may be about 10V, or about 5V. When the output voltage of the power adapter is about 10V, the first voltage conversion circuit and the second voltage conversion circuit are used to convert the voltage of about 10V into a voltage of about 5V. That is, the first voltage conversion circuit and the second voltage conversion circuit are in step-down mode. When the output voltage of the power adapter is about 5V, the first voltage conversion circuit and the second voltage conversion circuit are used to directly output the voltage of about 5V. That is, the output voltage of the first voltage conversion circuit is the same as the input voltage, the output voltage of the second voltage conversion circuit is the same as the input voltage, and the first voltage conversion circuit and the second voltage conversion circuit are in direct mode.

For example, as shown in FIG. 5 and FIG. 6 , in the scene of charging the electronic device with the screen on, the output voltage of the power adapter can be about 5V, and the first voltage conversion circuit and the second voltage conversion circuit are controlled to be in the direct mode, so that the first The output voltage of the voltage conversion circuit is the same as the input voltage, and the output voltage of the second voltage conversion circuit is also the same as the input voltage. After the voltage of about 5V output by the first voltage conversion circuit is transmitted through the first wired charging line, the battery of the electronic device is charged. After the voltage of about 5V transmitted by the second wired charging line is directly output through the second voltage conversion circuit, it is charged to the battery of the electronic device. Since the direct mode of the voltage conversion circuit generates less heat than the step-down mode, in the bright screen charging scenario, by setting the output voltage of the power adapter to about 5V, the first voltage conversion circuit and the second voltage conversion circuit are controlled It is a pass-through mode, which can further reduce the heat generation of electronic devices and increase the charging speed of bright screen charging.

For another example, as shown in FIG. 5 and FIG. 6 , in the scene where the screen of the electronic device is off and charging, the output voltage of the power adapter can be about 10V, and the first voltage conversion circuit and the second voltage conversion circuit are controlled to be in step-down mode, so that The output voltage of the first voltage conversion circuit is lower than the input voltage, and the output voltage of the second voltage conversion circuit is lower than the input voltage. After the voltage of about 5V output by the first voltage conversion circuit is transmitted through the first wired charging line, the battery of the electronic device is charged. After the voltage of about 10V transmitted by the second wired charging line is stepped down and output by the second voltage conversion circuit, it is charged to the battery of the electronic device.

The embodiment of the present application does not limit the output voltage of the power adapter when the electronic device is charged with the screen on or off, and the above is only an exemplary description. For example, in the scenario of charging an electronic device with the screen on, the output voltage of the power adapter can also be about 10V, and the first voltage conversion circuit and the second voltage conversion circuit are controlled to be in a step-down mode. That is, when the electronic device is charged by wire, it is also possible not to distinguish between the charging scene with the screen on and the charging scene with the screen off, and the output voltage of the power adapter is the same.

Exemplarily, taking at least a part of the outermost coil of the wireless charging coil multiplexed by the first wired charging line as an example, as shown in (b) in Figure 5, the first switch is S1, the second switch is S2, and the first switch is S2. There are two wired charging lines, and there are two second switches S2. The first ends of the two first wired charging lines are connected together and coupled to the output end of the first voltage conversion circuit through S1, and the second end of each first wired charging line is coupled with the battery of the electronic device through an S2 .

As shown in Figure 5 (a) and Figure 5 (b), when the electronic device is charged by wire, S1 and S2 are in the conduction state, and a current output by the power adapter passes through the first voltage conversion circuit in the electronic device Afterwards, power is supplied to the battery of the electronic device through the first wired charging circuit. The other current output by the power adapter passes through the second wired charging circuit in the electronic device, and then passes through the second voltage conversion circuit to supply power to the battery of the electronic device. When the electronic device is wirelessly charged, S1 and S2 are in the off state, the coil in the wireless charger and the wireless charging coil in the electronic device have electromagnetic induction, and the induced current is rectified by the rectifier circuit, and the HVSC chip converts about 20V The voltage is converted into a voltage of about 10V, and then the voltage of about 10V is converted into a voltage of about 5V by the second voltage conversion circuit, and then the battery of the electronic device is supplied with power.

It can be understood that in the case where the first wired charging circuit multiplexes the wireless charging coil, due to the large voltage generated on the wireless charging coil when the electronic device is wirelessly charged, the high voltage may cause damage to the battery and devices in the wired charging circuit. impact, and even lead to device failure. Therefore, this application can avoid the voltage generated on the wireless charging coil during wireless charging by setting the first switch and the second switch in the wired charging circuit, and turning off the first switch and the second switch when the electronic device is wirelessly charging. It will affect the devices in the wired charging circuit and the batteries of electronic equipment, and improve the reliability of electronic equipment charging. Moreover, by setting the first switch and the second switch in the wired charging circuit, the part of the wireless charging coil that is multiplexed by the first wired charging circuit can be used for both wireless charging and wired charging.

When the first wired charging line does not reuse the wireless charging coil, the first wired charging line is set correspondingly to the wireless charging coil, including: the first wired charging line is set along the outline of the wireless charging coil, the first wired charging line is connected to the wireless charging coil Electrically not connected. When the first wired charging line does not reuse the wireless charging coil, the number of the first wired charging line may be one or multiple, which is not limited in this embodiment of the present application.

For example, as shown in (c) in FIG. 5 , the first wired charging circuit is not electrically connected to the wireless charging coil, and the first wired charging coil is provided with a half-turn coil around the wireless charging coil along the outline of the wireless charging coil.

For another example, as shown in (d) in FIG. 5 , the first wired charging circuit is not electrically connected to the wireless charging coil, and the first wired charging coil is provided with a coil around the wireless charging coil along the outline of the wireless charging coil. There are two first wired charging lines, and the two first wired charging lines are connected in parallel.

In the case that the first wired charging line does not reuse the wireless charging coil, the electronic device can support a scenario where wired charging and wireless charging coexist. For example, the electronic device shown in (c) in FIG. 5 and (d) in FIG. 5 can support wired charging and wireless charging at the same time.

It can be understood that, compared with the electronic device shown in FIG. 1 , the electronic device shown in FIG. 5 adds a first wired charging line corresponding to the wireless charging coil in the electronic device, so that when the electronic device is charged by wire, the second A wired charging circuit and a second wired charging circuit can simultaneously supply power to a battery of an electronic device. The parallel connection of two wired charging lines can not only reduce the channel impedance, but also balance the heat generation on the charging FPC, so that the heat generation on the electronic equipment can be evenly distributed, and the charging speed of the electronic equipment can be improved. Moreover, when the electronic device is charging with the screen on, by setting the output voltage of the power adapter to about 5V, the first voltage conversion circuit and the second voltage conversion circuit are in a direct mode, which can reduce the heating of the main board of the electronic device and improve the charging performance. The electronic device shown in FIG. 5 can significantly increase the speed of charging when the screen is on, especially in the scene of charging the electronic device with the screen on. In addition, in this embodiment, when the first wired charging circuit multiplexes the wireless charging coil, by setting the first switch and the second switch, it is possible to avoid the voltage generated on the wireless charging coil from affecting the devices in the wired charging circuit during wireless charging.

Optionally, there may be one second voltage conversion circuit, or multiple (eg, two) second voltage conversion circuits. When there are multiple second voltage conversion circuits, the multiple second voltage conversion circuits are connected in parallel, and the second end of the first wired charging circuit is respectively coupled and connected to the battery of the electronic device through the multiple second voltage conversion circuits . FIG. 7 shows an example by taking the second voltage conversion circuit as an example.

FIG. 8 is a structural diagram of a charging principle of an electronic device. Referring to FIG. 7 , as shown in FIG. 8 , when the electronic device is charged by wire, the current output by the power adapter is transmitted through the first wired charging circuit in the electronic device, and then passes through the second voltage conversion circuit to supply power to the battery of the electronic device. When electronic equipment is wirelessly charged, electromagnetic induction occurs between the coil in the wireless charger and the wireless charging coil in the electronic equipment. After the induced current is rectified by the rectifier circuit, the voltage of about 20V is converted into a voltage of about 10V by the HVSC chip. After the voltage of about 10V is converted into a voltage of about 5V by the second voltage conversion circuit, power is supplied to the battery of the electronic device.

Optionally, when the electronic device is charged by wire, the output voltage of the power adapter may be about 10V or about 5V. When the output voltage of the power adapter is about 10V, the second voltage conversion circuit is used to convert the voltage of about 10V into a voltage of about 5V. That is, the second voltage converting circuit is in a step-down mode. When the output voltage of the power adapter is about 5V, the second voltage conversion circuit is used to directly output the voltage of about 5V. That is, the output voltage of the second voltage conversion circuit is the same as the input voltage, and the second voltage conversion circuit is in a direct mode.

For example, as shown in FIG. 7 and FIG. 8, in the scene of charging the electronic device with the screen on, the output voltage of the power adapter can be about 5V, and the second voltage conversion circuit is controlled to be in the direct mode, so that the output voltage of the second voltage conversion circuit Same as input voltage. After the voltage of about 5V output by the power adapter is transmitted through the first wired charging line, the voltage of about 5V is directly output through the second voltage conversion circuit to charge the battery of the electronic device. Since the direct mode of the second voltage conversion circuit generates less heat than the step-down mode, in the bright screen charging scenario, by setting the output voltage of the power adapter to about 5V, the second voltage conversion circuit is controlled to be in the direct mode, It can further reduce the heating of the motherboard of the electronic device and increase the charging speed of bright screen charging.

For another example, as shown in FIG. 7 and FIG. 8 , in the scenario where the screen of the electronic device is off and charging, the output voltage of the power adapter can be about 10V, and the second voltage conversion circuit is controlled to be in step-down mode, so that the output voltage of the second voltage conversion circuit The output voltage is less than the input voltage. After the voltage of about 10V output by the power adapter is transmitted through the first wired charging line, it is stepped down by the second voltage conversion circuit to output a voltage of about 5V to charge the battery of the electronic device.

The embodiment of the present application does not limit the output voltage of the power adapter when the electronic device is charged with the screen on or off, and the above is only an exemplary description. For example, in the scene of charging the electronic device with the screen on, the output voltage of the power adapter can also be about 10V, and the second voltage conversion circuit is controlled to be in step-down mode, so that the output voltage of the second voltage conversion circuit is lower than the input voltage. After the voltage of about 10V output by the power adapter is transmitted through the first wired charging line, it is stepped down by the second voltage conversion circuit to output a voltage of about 5V to charge the battery of the electronic device. That is, when the electronic device is charged by wire, it is also possible not to distinguish between the charging scene with the screen on and the charging scene with the screen off, and the output voltage of the power adapter is the same.

The first wired charging circuit in FIG. 7 may or may not multiplex the wireless charging coil.

Regarding the specific implementation manner when the first wired charging circuit multiplexes the wireless charging coil, reference may be made to the relevant descriptions of the foregoing embodiments, and details are not repeated here.

In the case that the first wired charging circuit multiplexes the wireless charging coil, the wired charging circuit may further include a first switch and a second switch.

The embodiment of the present application does not limit the specific number of the first switch and the second switch. (a) in FIG. One switch and two second switches are used as an example for illustration.

It can be understood that in the case where the first wired charging circuit multiplexes the wireless charging coil, due to the large voltage generated on the wireless charging coil when the electronic device is wirelessly charged, the high voltage may cause damage to the battery and devices in the wired charging circuit. influence, and even lead to device failure. Therefore, this application can avoid the voltage generated on the wireless charging coil during wireless charging by setting the first switch and the second switch in the wired charging circuit, and turning off the first switch and the second switch when the electronic device is wirelessly charging. It will affect the devices in the wired charging circuit and the batteries of electronic equipment, etc., and improve the reliability of electronic equipment charging. Moreover, by setting the first switch and the second switch in the wired charging circuit, the part of the wireless charging coil that is multiplexed by the first wired charging circuit can be used for both wireless charging and wired charging.

For example, as shown in (c) of FIG. 7 , the first wired charging circuit is not electrically connected to the wireless charging coil, and the first wired charging coil is provided with a half-turn coil around the wireless charging coil along the outline of the wireless charging coil. The first wired charging line is one, the first end of the first wired charging line is used to couple with the power adapter, the second end of the first wired charging line is coupled to the input end of the second voltage conversion circuit, and the second The output terminal of the voltage conversion circuit is coupled and connected with the battery of the electronic device.

It can be understood that, compared with the electronic device shown in FIG. 1, the electronic device shown in FIG. 7 can make the first wired charging circuit larger or wider by omitting the charging FPC in the electronic device, which can reduce the charging time. The path impedance of the small wired charging circuit improves the charging speed of electronic devices. Moreover, in this embodiment, when the electronic device is being charged with the screen on, the output voltage of the power adapter can be set to about 5V, and the second voltage conversion circuit is in a direct mode, which can further reduce the heating of the main board of the electronic device and increase the speed of charging the electronic device with the screen on. . The electronic device shown in FIG. 7 can significantly increase the speed of charging when the screen is on, especially in the scene of charging the electronic device with the screen on. In addition, in this embodiment, when the first wired charging circuit multiplexes the wireless charging coil, by setting the first switch and the second switch, it is possible to prevent the voltage generated on the wireless charging coil from affecting the wired charging circuit during wireless charging of the electronic device. Devices in the device and batteries of electronic equipment, etc. will be affected.

The fourth circuit structure: as shown in Figure 9, the wired charging circuit also includes a second wired charging circuit connected in parallel with the first wired charging circuit, and connected in series with the first wired charging circuit and the second wired charging circuit connected in parallel The second voltage conversion circuit. When the electronic equipment is charged by wire, the electronic equipment is charged through the first wired charging circuit and the second wired charging circuit.

Optionally, there may be one second voltage conversion circuit, or multiple (eg, two) second voltage conversion circuits. When there are multiple second voltage conversion circuits, the multiple second voltage conversion circuits are connected in parallel, and the second end of the first wired charging circuit is respectively coupled and connected to the battery of the electronic device through the multiple second voltage conversion circuits . FIG. 9 is an exemplary diagram taking the second voltage conversion circuit as an example.

FIG. 10 is a schematic structural diagram of charging an electronic device. Referring to FIG. 9, as shown in FIG. 10, when the electronic device is charged by wire, the current output by the power adapter passes through the first wired charging circuit and the second wired charging circuit connected in parallel, and then passes through the second voltage conversion circuit to the electronic device. Battery powered. When electronic equipment is wirelessly charged, electromagnetic induction occurs between the coil in the wireless charger and the wireless charging coil in the electronic equipment. After the induced current is rectified by the rectifier circuit, the voltage of about 20V is converted into a voltage of about 10V by the HVSC chip. After the voltage of about 10V is converted into a voltage of about 5V by the second voltage conversion circuit, power is supplied to the battery of the electronic device. That is, when the electronic device is charged by wire, the battery of the electronic device is jointly charged through the first wired charging circuit and the second wired charging circuit.

For example, as shown in FIG. 9 and FIG. 10 , in the scene of charging the electronic device with the screen on, the output voltage of the power adapter can be about 5V, and the second voltage conversion circuit is controlled to be in the direct mode, so that the output voltage of the second voltage conversion circuit Same as the input voltage. After the voltage of about 5V output by the power adapter is transmitted in parallel through the first wired charging line and the second wired charging line, the voltage of about 5V is directly output through the second voltage conversion circuit to charge the battery of the electronic device. Since the direct mode of the second voltage conversion circuit generates less heat than the step-down mode, in the bright screen charging scenario, by setting the output voltage of the power adapter to about 5V, the second voltage conversion circuit is controlled to be in the direct mode, It can further reduce the heating of the motherboard of the electronic device and increase the charging speed of bright screen charging.

For another example, as shown in FIG. 9 and FIG. 10 , in the scene where the screen of the electronic device is off and charging, the output voltage of the power adapter can be about 10V, and the second voltage conversion circuit is controlled to be in step-down mode, so that the output voltage of the second voltage conversion circuit The output voltage is less than the input voltage. After the voltage of about 10V output by the power adapter is transmitted in parallel through the first wired charging line and the second wired charging line, the voltage of about 5V is stepped down by the second voltage conversion circuit to charge the battery of the electronic device.

The embodiment of the present application does not limit the output voltage of the power adapter when the electronic device is charged with the screen on or off, and the above is only an exemplary description. For example, in the scenario of charging the electronic device with the screen on, the output voltage of the power adapter can also be about 10V, and the second voltage conversion circuit is controlled to be in a step-down mode. That is, when the electronic device is charged by wire, it is also possible not to distinguish between the charging scene with the screen on and the charging scene with the screen off, and the output voltage of the power adapter is the same.

When the first wired charging line multiplexes the wireless charging coil, the corresponding setting of the first wired charging line and the wireless charging coil includes but is not limited to: the first wired charging line is at least a part of the wireless charging coil, and the first wired charging line is wireless charging At least a part of the outermost turn of the coil, the first wired charging line is at least a part of the outermost turn of the first-layer coil. Regarding the specific implementation manner when the first wired charging circuit multiplexes the wireless charging coil, reference may be made to the relevant descriptions of the foregoing embodiments, and details are not repeated here.

Exemplarily, taking the first wired charging circuit as an example of multiplexing a part of the outermost coil of the wireless charging coil, as shown in (a) in Figure 9, the first switch is S1, the second switch is S2, and the first wired There is one charging circuit, and one second switch S2. The first end of the first wired charging circuit is used to couple with the power adapter through S1, and the second end of the first wired charging circuit is coupled to the input end of the second voltage conversion circuit through S2.

Exemplarily, taking at least a part of the outermost coil of the wireless charging coil multiplexed by the first wired charging line as an example, as shown in (b) in FIG. 9, the first switch is S1, the second switch is S2, and the first switch is S2. There are two wired charging lines, and there are two second switches S2. The first ends of the two first wired charging lines are connected together, the first ends of the two first wired charging lines are used to couple with the power adapter through S1, and the second ends of each first wired charging line are connected through one S2 coupled to the input of the second voltage conversion circuit.

As shown in Figure 9 (a) and Figure 9 (b), when the electronic device is charged by wire, S1 and S2 are in the conduction state, and the current output by the power adapter passes through the first wired charging line and the second wired charging line connected in parallel. 2. After transmission by the wired charging line, power is supplied to the battery of the electronic device through the second voltage conversion circuit in the electronic device. When the electronic device is wirelessly charged, S1 and S2 are in the off state, the coil in the wireless charger and the wireless charging coil in the electronic device have electromagnetic induction, and the induced current is rectified by the rectifier circuit, and the HVSC chip converts about 20V The voltage is converted into a voltage of about 10V, and then the voltage of about 10V is converted into a voltage of about 5V by the second voltage conversion circuit, and then the battery of the electronic device is supplied with power.

It can be understood that in the case where the first wired charging circuit multiplexes the wireless charging coil, due to the large voltage generated on the wireless charging coil when the electronic device is wirelessly charged, the high voltage may cause damage to the battery and devices in the wired charging circuit. influence, and even lead to device failure. Therefore, this application can avoid the voltage generated on the wireless charging coil during wireless charging by setting the first switch and the second switch in the wired charging circuit, and turning off the first switch and the second switch when the electronic device is wirelessly charging. It will affect the devices in the wired charging circuit and the batteries of electronic equipment, and improve the reliability of electronic equipment charging. Moreover, by setting the first switch and the second switch in the wired charging circuit, the part of the wireless charging coil that is multiplexed by the first wired charging circuit can be used for both wireless charging and wired charging.

For example, as shown in (c) in FIG. 9 , the first wired charging circuit is not electrically connected to the wireless charging coil, and the first wired charging coil is provided with a half-turn coil around the wireless charging coil along the outline of the wireless charging coil. There is one first wired charging line, the first end of the first wired charging line is used for coupling with the power adapter, and the second end of the first wired charging line is coupled to the input end of the second voltage conversion circuit.

For another example, as shown in (d) of FIG. 9 , the first wired charging circuit is not electrically connected to the wireless charging coil, and the first wired charging coil is provided with a coil around the wireless charging coil along the outline of the wireless charging coil.

The first ends of the two first wired charging lines are used for coupling with the power adapter, and the second ends of the two first wired charging lines are coupled to the input end of the second voltage conversion circuit.

It can be understood that, compared with the electronic device shown in FIG. 1 , the electronic device shown in FIG. 9 adds a first wired charging line corresponding to the wireless charging coil to the electronic device, so that when the electronic device is charged by wire, the second A wired charging circuit and a second wired charging circuit can simultaneously supply power to a battery of an electronic device. The parallel connection of two wired charging lines can not only reduce the channel impedance, but also balance the heat generation on the charging FPC, so that the heat generation on the electronic equipment can be evenly distributed, and the speed of bright screen charging can be improved. The electronic device shown in FIG. 9 can significantly increase the speed of charging when the screen is on, especially in the scene of charging the electronic device with the screen on. Moreover, when the electronic device is charging with the screen on, by setting the output voltage of the power adapter to about 5V, the second voltage conversion circuit is in a direct mode, which can reduce the heating of the main board of the electronic device and improve the charging performance. In addition, in this embodiment, when the first wired charging circuit multiplexes the wireless charging coil, by setting the first switch and the second switch, it is possible to avoid the voltage generated on the wireless charging coil from affecting the devices in the wired charging circuit during wireless charging. It will affect the battery of electronic equipment, etc., and improve the reliability of charging electronic equipment.

For example, the electronic device may be the electronic device shown in (a) in FIG. 7 or (b) in FIG. 7 .

Optionally, the wired charging circuit in the electronic device may also include a second wired charging circuit connected in parallel with the first wired charging circuit. The conversion circuits are connected in series. For example, the electronic device may be the electronic device shown in (a) in FIG. 9 or (b) in FIG. 9 .

In this embodiment, the corresponding setting of the first wired charging circuit and the wireless charging coil includes: the first wired charging circuit is at least a part of the wireless charging coil. Or, the first wired charging circuit is at least a part of the outermost turn of the wireless charging coil. Or, the first wired charging line is at least a part of the outermost turn of the first-layer coil. That is, in this embodiment, the first wired charging circuit multiplexes the wireless charging coil.

Optionally, if the electronic device is charged by wire when it is turned off, it may be detected that the charging type of the electronic device is wired charging when a power adapter is plugged into the charging port of the electronic device.

S1102. When the charging type of the electronic device is wireless charging, control the first switch and the second switch to be turned off.

For example, take the electronic equipment as (a) in Figure 3, (b) in Figure 3, (a) in Figure 5, (b) in Figure 5, (a) in Figure 7, and (b), take the electronic device shown in (a) in Figure 9 or (b) in Figure 9 as an example, when the charging type of the electronic device is wireless charging, control the first switch S1 and the second switch S2 is turned off, the induced current generated by the wireless charging coil in the electronic device is rectified by the rectifier circuit, and the voltage of about 20V is converted into a voltage of about 10V through the HVSC chip, and then the voltage of about 10V is converted into a voltage of about 10V by the second voltage conversion circuit. After a voltage of about 5V, it supplies power to the battery of the electronic device.

That is to say, when the charging type of the electronic device is wireless charging, the first switch and the second switch are in the off state, so the large voltage generated on the wireless charging coil will not affect the devices in the wired charging circuit or the battery of the electronic device. This can improve the reliability of charging electronic devices.

S1103. When the charging type of the electronic device is wired charging, control the first switch and the second switch to be turned on.

Optionally, the default state of the first switch and the second switch may be an off state.

For example, taking the electronic device as shown in (a) in FIG. 3 or (b) in FIG. 3 as an example, if the electronic device is powered on and performing wired charging, it is detected that the charging type of the electronic device is wired charging Afterwards, the first switch S1 and the second switch S2 are controlled to be turned on, and the current output by the power adapter passes through the first voltage conversion circuit in the electronic device, and then supplies power to the battery of the electronic device through the first wired charging circuit. If the power of the electronic device is too low, wired charging is performed in the off state. When the charging port of the electronic device is plugged into a power adapter, the first switch S1 and the second switch S2 can be controlled to be turned on through a hardware circuit.

For another example, take the electronic device as shown in (a) in FIG. 5 or (b) in FIG. After charging, the first switch S1 and the second switch S2 are controlled to be turned on, and a current output by the power adapter passes through the first voltage conversion circuit in the electronic device, and then supplies power to the battery of the electronic device through the first wired charging circuit. The other current output by the power adapter passes through the second wired charging circuit in the electronic device, and then passes through the second voltage conversion circuit to supply power to the battery of the electronic device. If the power of the electronic device is too low and the wired charging is performed in the off state, the battery can be charged through the second wired charging line first. After the electronic device is turned on, when it is detected that the charging type of the electronic device is wired charging, the first switch is controlled. S1 and the second switch S2 are turned on.

For another example, taking the electronic device as shown in (a) in FIG. 7 or (b) in FIG. 7 as an example, when the charging type of the electronic device is wired charging, control the first switch S1 and the second switch S2 is turned on, the current output by the power adapter is transmitted through the first wired charging circuit, and then passes through the second voltage conversion circuit to supply power to the battery of the electronic device.

For another example, taking the electronic device as shown in (a) in FIG. 9 or (b) in FIG. 9 as an example, when the charging type of the electronic device is wired charging, control the first switch S1 and the second switch S2 is turned on, and the current output by the power adapter is transmitted through the first wired charging circuit and the second wired charging circuit connected in parallel, and then passes through the second voltage conversion circuit in the electronic device to supply power to the battery of the electronic device.

It can be understood that in the case that the first wired charging circuit multiplexes the wireless charging coil, the first switch and the second switch are respectively arranged on both sides of the first wired charging circuit, and the first switch is turned off when the electronic device is wirelessly charged. The switch and the second switch are connected to the first switch and the second switch when the electronic device is charged by wire, so that the electronic device does not affect the wireless charging during the wired charging, and the wireless charging does not affect the wired charging. While the charging speed of the electronic device can be increased (especially the charging speed of the electronic device with a bright screen), the reliability of the charging of the electronic device can be improved.

Optionally, in this embodiment of the present application, when an electronic device is charged by wire, it may distinguish between a charging scene with the screen on and a charging scene with the screen off, or may not distinguish between a charging scene with the screen on and a charging scene with the screen off. If the electronic device distinguishes between a charging scene with the screen on and a charging scene with the screen off when performing wired charging, the above control method may further include: detecting that the charging scene of the electronic device is charging with the screen on or charging with the screen off. When the electronic device is charging with the screen on and the charging type is wired charging, the output voltage of the power adapter is controlled to be the first voltage, and the first voltage conversion circuit and/or the second voltage conversion circuit are controlled to be in a direct mode. When the electronic device is charging with the screen off and the charging type is wired charging, control the output voltage of the power adapter to be the second voltage, and control the first voltage conversion circuit and/or the second voltage conversion circuit to a step-down mode. The first voltage may be smaller than the second voltage.

For example, when an electronic device is charged with a bright screen, the output voltage of the power adapter can be controlled to be about 5V. When the screen of the electronic device is off and wired charging, the output voltage of the power adapter can be controlled to be about 10V. 3 to 10 above, it can be seen that when the output voltage of the power adapter is about 5V, the first voltage conversion circuit and/or the second voltage conversion circuit are in the direct mode to supply power to the battery of the electronic device. Since the direct mode of the voltage conversion circuit is relatively The step-down mode has low power consumption and low heat generation, so it can further increase the speed of bright screen charging of electronic devices.
