Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to an electronic device and its control method. Background Technology

[0002] Currently, fast charging technology can greatly improve the charging speed of electronic devices. However, in scenarios where the screen is on while charging (such as when a user is watching videos or playing games while charging), the high temperature of the electronic device limits the charging speed, resulting in slower charging speeds in these scenarios. Summary of the Invention

[0003] This application provides an electronic device and its control method, which can improve the charging speed of the electronic device.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0005] A first aspect of this application provides an electronic device including 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 line, which is correspondingly disposed with the wireless charging coil. When the electronic device is wirelessly charged, it is charged via the wireless charging circuit; when the electronic device is wired charged, it is charged via the wired charging circuit.

[0006] Based on this solution, by eliminating the charging FPC in the electronic device, the first wired charging line can be made larger or wider, reducing the path impedance of the wired charging circuit and improving the charging speed of the electronic device. Furthermore, in this solution, when the electronic device is wired charged, it charges the battery through the wired charging line corresponding to the wireless charging coil. The charging current can flow directly into the battery from the port of the first wired charging line, bypassing the circuitry on the motherboard. This reduces heat generation on the motherboard and further improves the charging speed. This solution is particularly effective in scenarios where the screen is on while charging, significantly improving the charging speed. Additionally, by eliminating the charging FPC, the width of the electronic device can be reduced.

[0007] In one possible implementation, the first wired charging line is configured to correspond with the wireless charging coil, including: the first wired charging line being at least a part of the wireless charging coil.

[0008] Based on this solution, the first wired charging line can reuse at least a portion of the wireless charging coil. Since the charging FPC is eliminated in the electronic device, there is more space in the electronic device to set up the wireless charging coil. The increase in the size of the wireless charging coil can reduce the path impedance of the wired charging circuit when the first wired charging line reuses the wireless charging coil, thereby improving the charging speed of the electronic device, especially significantly improving the charging speed of the electronic device when the screen is on.

[0009] In one possible implementation, the first wired charging line is configured to correspond to the wireless charging coil, including: the first wired charging line being at least a portion of the outermost turn of the wireless charging coil.

[0010] Based on this solution, the first wired charging circuit can reuse at least a portion of the outermost turn of the wireless charging coil. On the one hand, this can reduce the path impedance of the wired charging circuit and improve the charging speed of electronic devices, especially significantly improving the charging speed of electronic devices with the screen on. On the other hand, when reusing the wireless charging coil in the first wired charging circuit, the manufacturing process can be simplified by reusing at least a portion of the outermost turn of the wireless charging coil.

[0011] In one possible implementation, the wireless charging coil includes a first layer coil and a second layer coil in a direction perpendicular to the screen of the electronic device; the first wired charging line is configured correspondingly to the wireless charging coil, including: the first wired charging line is at least a portion of the outermost turn of the first layer coil.

[0012] Based on this solution, the first wired charging circuit can reuse at least a portion of the outermost turn of the wireless charging coil, which can reduce the path impedance of the wired charging circuit and improve the charging speed of electronic devices, especially significantly improving the charging speed of electronic devices with the screen on.

[0013] In one possible implementation, the first wired charging line is configured correspondingly to the wireless charging coil, including: the first wired charging line is configured along the outline of the wireless charging coil, and the first wired charging line and the wireless charging coil are not electrically connected.

[0014] Based on this solution, the first wired charging line can be installed without reusing the wireless charging coil, following the outline of the wireless charging coil. Since the charging FPC is eliminated in the electronic device, there is more space for the first wired charging line, reducing the path impedance of the wired charging circuit and improving the charging speed. This solution is particularly effective in scenarios where the electronic device is charging with the screen on, significantly improving the charging speed. In this solution, because the first wired charging line is not electrically connected to the wireless charging coil, wired and wireless charging of the electronic device do not interfere with each other.

[0015] In one possible implementation, the wireless charging coil includes a first layer coil and a second layer coil in a direction perpendicular to the screen of the electronic device; a first wired charging line is correspondingly arranged with respect to the wireless charging coil, including: the first wired charging line is arranged along the outline of the first layer coil, and the first wired charging line is not electrically connected to the wireless charging coil.

[0016] Based on this solution, the first wired charging line can be set without reusing the wireless charging coil and can be set along the outline of the first layer of coil in the wireless charging coil. This reduces the impact of setting the first wired charging line on the size of the wireless charging coil without changing the size of the electronic device.

[0017] In one possible implementation, the first wired charging line is made of the same material as the wireless charging coil.

[0018] Based on this solution, the first wired charging circuit and the wireless charging coil can be made of the same material, which can reduce the complexity of the process.

[0019] In one possible implementation, the wired charging circuit further includes a first voltage conversion circuit connected in series with the first wired charging line. A first end of the first wired charging line is used to couple to a power adapter through the first voltage conversion circuit, and a second end of the first wired charging line is coupled to the battery of the electronic device.

[0020] Based on this solution, when the electronic device is wired charged, 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 via the first wired charging line. Since the charging current can flow directly into the battery of the electronic device from the port of the first wired charging line without passing through the circuitry on the motherboard, it reduces heat generation on the motherboard and improves the charging speed of the electronic device. This solution is particularly effective in scenarios where the electronic device is charging with the screen on, significantly improving the charging speed. Optionally, when the electronic device is wired and charging with the screen on, the first voltage conversion circuit can be in pass-through mode. Since the pass-through mode of the first voltage conversion circuit generates less heat than the buck mode, it can further improve the charging speed when the screen is on.

[0021] In one possible implementation, the wired charging circuit further includes a first switch, a second switch, and a first voltage conversion circuit connected in series with the first wired charging line. The second switch can be one or more. A first end of the first wired charging line is coupled to the output of the first voltage conversion circuit via the first switch. The input of the first voltage conversion circuit is coupled to a power adapter. A second end of the first wired charging line is coupled to the battery of the electronic device via the second switch. When the electronic device is wirelessly charging, the first and second switches are in an off state; when the electronic device is wired charging, the first and second switches are in a conducting state.

[0022] Based on this solution, when the wireless charging coil is reused in the first wired charging circuit, the high voltage generated on the wireless charging coil during wireless charging may affect the battery and components in the wired charging circuit, potentially causing component failure. Therefore, this solution, by setting a first switch and a second switch in the wired charging circuit and turning off both switches when the electronic device is wirelessly charging, avoids the voltage generated on the wireless charging coil affecting the components in the wired charging circuit and the battery of the electronic device, thus improving the reliability of charging. Furthermore, during wired charging, since the wired charging voltage is DC while the rectifier circuit's drive voltage is AC, wired charging does not affect the wireless charging circuit. This solution, by setting a first switch and a second switch in the wired charging circuit, allows the portion of the wireless charging coil reused by the first wired charging circuit to be used for both wireless and wired charging when the first wired charging circuit reuses the wireless charging coil.

[0023] In one possible implementation, the wired charging circuit further includes a second voltage conversion circuit and a second wired charging line connected in series, with the second voltage conversion circuit and the second wired charging line connected in parallel with the first voltage conversion circuit and the first wired charging line connected in series. When the electronic device is wired charged, it is charged through the first wired charging line and the second wired charging line.

[0024] Based on this solution, by adding a first wired charging line corresponding to the wireless charging coil in the electronic device, both the first and second wired charging lines can simultaneously power the battery of the electronic device during wired charging. This solution, by connecting two wired charging lines in parallel, not only reduces path impedance but also balances the heat generated on the charging FPC, resulting in more even heat distribution and improved charging speed. This solution is particularly effective in scenarios where the screen is on during charging, significantly increasing the charging speed. Optionally, when the electronic device is wired and charging with the screen on, the first and second voltage conversion circuits can be in pass-through mode. Since pass-through mode generates less heat than buck mode, setting the second voltage conversion circuit to pass-through mode reduces the heat generated by the electronic device's motherboard, further improving the charging speed when the screen is on.

[0025] In one possible implementation, the wired charging circuit further includes a second voltage conversion circuit connected in series with the first wired charging line. The first end of the first wired charging line is used to couple to 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 output end of the second voltage conversion circuit is coupled to the battery of the electronic device.

[0026] Based on this solution, during wired charging of the electronic device, the current output from the power adapter is transmitted through the first wired charging line in the electronic device and then supplies power to the battery of the electronic device through the second voltage conversion circuit. This solution eliminates the need for the charging FPC in the electronic device, allowing the first wired charging line to be larger or wider, reducing the path impedance of the wired charging circuit and improving the charging speed of the electronic device. This solution is particularly effective in scenarios where the electronic device is charging with the screen on, significantly improving the charging speed. Optionally, when the electronic device is wired and charging with the screen on, the second voltage conversion circuit can be in pass-through mode. Since the pass-through mode of the second voltage conversion circuit generates less heat than the buck mode, it can reduce the heat generated by the motherboard of the electronic device, further improving the charging speed when the screen is on.

[0027] In one possible implementation, the wired charging circuit further includes a first switch and a second switch, and a second voltage conversion circuit connected in series with the first wired charging line, wherein there are one or more second switches. A first end of the first wired charging line is coupled to a power adapter via the first switch, a second end of the first wired charging line is coupled to the input of the second voltage conversion circuit via the second switch, and the output of the second voltage conversion circuit is coupled to the battery of the electronic device. When the electronic device is wirelessly charging, the first switch and the second switch are in an off state; when the electronic device is wired charging, the first switch and the second switch are in a conducting state.

[0028] Based on this solution, when the wireless charging coil is reused in the first wired charging circuit, the high voltage generated on the wireless charging coil during wireless charging may affect the battery and components in the wired charging circuit, potentially causing component failure. Therefore, this solution, by setting a first switch and a second switch in the wired charging circuit and turning off both switches when the electronic device is wirelessly charging, can prevent the voltage generated on the wireless charging coil from affecting the components in the wired charging circuit and the battery of the electronic device, thus improving the reliability of charging. Furthermore, by setting the first and second switches in the wired charging circuit, this solution allows the portion of the wireless charging coil reused by the first wired charging circuit to be used for both wireless and wired charging.

[0029] In one possible implementation, the wired charging circuit further includes a second wired charging line connected in parallel with the first wired charging line. After the first and second wired charging lines are connected in parallel, they are then connected in series with the second voltage conversion circuit.

[0030] Based on this solution, by adding a first wired charging line corresponding to the wireless charging coil to the electronic device, both the first and second wired charging lines can simultaneously power the battery of the electronic device during wired charging. Connecting the two wired charging lines in parallel not only reduces path impedance but also evens out heat generation on the charging FPC, resulting in more uniform heat distribution and improved charging speed. This solution significantly improves charging speed, especially in scenarios where the screen is on. Optionally, during screen-on charging, the power adapter's output voltage can be set to approximately 5V, and the second voltage conversion circuit can be controlled in direct-flow mode to further reduce motherboard heat generation and improve charging performance.

[0031] A second aspect of this application provides a control method for 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 voltage conversion circuit and a first wired charging line connected in series, as well as a first switch and a second switch. The first wired charging line is correspondingly arranged with the wireless charging coil. A first end of the first wired charging line is coupled to the output end of the first voltage conversion circuit through the first switch, and the input end of the first voltage conversion circuit is used for coupling connection with a power adapter. A second end of the first wired charging line is coupled to the battery of the electronic device through the second switch. The control method includes: detecting the charging type of the electronic device, which includes wired charging and wireless charging; when the charging type of the electronic device is wireless charging, controlling the first switch and the second switch to turn off; and when the charging type of the electronic device is wired charging, controlling the first switch and the second switch to turn on.

[0032] In one possible implementation, the wired charging circuit further includes a second voltage conversion circuit and a second wired charging line connected in series, wherein the second voltage conversion circuit and the second wired charging line are connected in parallel with the first voltage conversion circuit and the first wired charging line connected in series.

[0033] A third aspect of this application provides a control method for 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 line and a second voltage conversion circuit connected in series, as well as a first switch and a second switch. The first wired charging line is correspondingly arranged with the wireless charging coil. A first end of the first wired charging line is coupled to a power adapter via the first switch, and a second end of the first wired charging line is coupled to the input terminal of the second voltage conversion circuit via the second switch. The output terminal of the second voltage conversion circuit is coupled to the battery of the electronic device. The control method includes: detecting the charging type of the electronic device, which includes wired charging and wireless charging; when the charging type of the electronic device is wireless charging, controlling the first switch and the second switch to turn off; and when the charging type of the electronic device is wired charging, controlling the first switch and the second switch to turn on.

[0034] In one possible implementation, the wired charging circuit further includes a second wired charging line connected in parallel with the first wired charging line. After the first and second wired charging lines are connected in parallel, they are then connected in series with the second voltage conversion circuit.

[0035] In conjunction with the second or third aspect above, in one possible implementation, the first wired charging line is configured to correspond with the wireless charging coil, including: the first wired charging line being at least a part of the wireless charging coil.

[0036] In conjunction with the second or third aspect above, in one possible implementation, the first wired charging line is configured to correspond with the wireless charging coil, including: the first wired charging line being at least a portion of the outermost turn of the wireless charging coil.

[0037] In conjunction with the second or third aspect above, in one possible implementation, the wireless charging coil includes a first layer coil and a second layer coil in a direction perpendicular to the screen of the electronic device; a first wired charging line is correspondingly arranged with the wireless charging coil, including: the first wired charging line is at least a portion of the outermost turn of the first layer coil.

[0038] In conjunction with the second or third aspect above, in one possible implementation, the first wired charging circuit is made of the same material as the wireless charging coil.

[0039] The effects of the various implementation methods in the second and third aspects mentioned above can be described with reference to the corresponding effects in the first aspect, and will not be repeated here. Attached Figure Description

[0051] The technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings. In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, and c can be single or multiple. Furthermore, to facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order. For example, the "first" in the first wired charging circuit and the "second" in the second wired charging circuit in the embodiments of this application are only used to distinguish different wired charging circuits. The descriptions of "first" and "second" appearing in the embodiments of this application are only for illustrative purposes and to distinguish the described objects; they do not indicate any order and do not represent a special limitation on the number of devices in the embodiments of this application, nor do they constitute any limitation on the embodiments of this application.

[0052] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0053] When an electronic device is charging via wired connection while the screen is on, the increased overall temperature of the device will limit the charging speed, resulting in slower charging when the screen is on.

[0054] Figure 1This is a schematic diagram of the structure of an electronic device. For example... Figure 1 As shown, during wired charging of an electronic device, current flows from the power adapter into the flexible printed circuit board (FPC) within the device. The current then passes through two switched capacitor (SC) charging chips, converting the approximately 10V voltage to approximately 5V before supplying power to the device's battery. During wireless charging, the coil in the wireless charger and the wireless charging coil in the electronic device generate an induced current. This induced current is rectified by a rectifier circuit and then passes through a high-voltage switched capacitor (HVSC) charging chip, converting the approximately 20V voltage to approximately 10V. Finally, the two SC charging chips convert the approximately 10V voltage to approximately 5V before supplying power to the device's battery.

[0055] Optionally, the embodiments of this application do not limit the number of SC charging chips in the electronic device. Figure 1 The following example illustrates an electronic device that includes two SC charging chips (SC1 and SC2). In practical applications, the number of SC charging chips depends on the number of connector pairs on the battery of the electronic device; for example, the electronic device may also include only one SC charging chip.

[0056] Combination Figure 1 As shown, in scenarios where the screen is on while the electronic device is charging, such as watching videos, playing games, or shopping online, the chips on the motherboard of the electronic device (e.g., system-on-chip, SoC, which may include...) are constantly active due to the screen being on. Figure 1 As shown, SC1 and SC2 will generate heat. If the electronic device is wired-charged while the screen is on, both SC chips and the charging FPC will generate heat, which will result in a higher temperature on the motherboard of the electronic device and affect the charging speed while the screen is on.

[0057] For example, reducing path impedance or increasing heat dissipation measures can reduce the heat generated by electronic devices in screen-on scenarios and improve charging speed. For instance, path impedance can be reduced by increasing the thickness of the charging FPC, and heat dissipation can be achieved by adding vacuum chambers (VCs) and graphite. However, increasing the thickness of the charging FPC, as well as adding VCs and graphite, will increase the overall thickness of the electronic device, resulting in higher costs.

[0058] To improve the charging speed of electronic devices, especially the charging speed while the screen is on, this application provides an electronic device that can improve the charging speed of the electronic device during wired charging, particularly in scenarios where the screen is on, significantly improving the charging speed. Furthermore, this application can improve the charging speed while the screen is on without changing the size of the electronic device, and may even reduce the size of the electronic device.

[0059] The electronic device provided in this application embodiment can improve the charging speed in scenarios where the screen is on and charging, and it can also improve the charging speed when the screen is off and charging. This application embodiment does not limit the specific scenario for charging the electronic device with the screen on. For example, scenarios for charging the electronic device with the screen on include, but are not limited to, users watching videos while charging, playing games while charging, shopping online while charging, etc. The screen-on charging scenario in this application embodiment is applicable to any scenario where the electronic device is charged while its screen is on.

[0060] This application's embodiments apply to electronic devices that include wireless charging coils. For example... Figure 2 As shown, the electronic device includes a wireless charging coil, which can be a multi-turn coil.

[0061] Optionally, the wireless charging coil in the electronic device can be a single-layer coil, or it can include multiple layers of coils in the direction perpendicular to the screen of the electronic device, with each layer of coil having multiple turns. The embodiments of this application do not limit the number of layers and turns of the wireless charging coil in the electronic device.

[0062] This application provides an electronic device, which 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 line, wherein the first wired charging line is correspondingly arranged with the wireless charging coil.

[0063] When an electronic device is wirelessly charged, it is charged via a wireless charging circuit. When an electronic device is wired, it is charged via a wired charging circuit.

[0064] The wired charging circuit in this application embodiment can include various different circuit structures. Under different circuit structures, the first wired charging line can reuse the wireless charging coil or not reuse the wireless charging coil. The process of wired and wireless charging of electronic devices, as well as the specific form of the first wired charging line, will be described in detail below with reference to four different circuit structures of the wired charging circuit.

[0065] The first type of circuit structure: as follows Figure 3As shown, the wired charging circuit also includes a first voltage conversion circuit connected in series with the first wired charging line. A first end of the first wired charging line is used to couple to a power adapter via the first voltage conversion circuit, and a second end of the first wired charging line is coupled to the battery of the electronic device.

[0066] Optionally, the wireless charging circuit may further include a rectifier circuit, an HVSC, and a second voltage conversion circuit. The input terminal of the rectifier circuit is coupled to the wireless charging coil, the output terminal of the rectifier circuit is coupled to the input terminal of the HVSC, the output terminal of the HVSC is coupled to the input terminal of the second voltage conversion circuit, and the output terminal of the second voltage conversion circuit is coupled to the battery of the electronic device. The number of second voltage conversion circuits is not limited in this embodiment; it depends on the number of connector pairs on the battery of the electronic device. Figure 3 , Figure 5 , Figure 7 and Figure 9 The second voltage conversion circuit is illustrated as an example. In practical applications, there may be two second voltage conversion circuits in electronic devices.

[0067] Figure 4 This is a schematic diagram illustrating the charging principle of an electronic device. (Combined with...) Figure 3 ,like Figure 4 As shown, during wired charging of the electronic device, the current output from 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 via the first wired charging line. During wireless charging of the electronic device, the coil in the wireless charger and the wireless charging coil in the electronic device undergo electromagnetic induction. The resulting induced current is rectified by the rectifier circuit, and then the HVSC chip converts the voltage of approximately 20V to approximately 10V. The second voltage conversion circuit then converts the approximately 10V voltage to approximately 5V before supplying power to the battery of the electronic device.

[0068] Optionally, when the electronic device is wired charged, the power adapter's output voltage can be approximately 10V or approximately 5V. When the power adapter's output voltage is approximately 10V, the first voltage conversion circuit converts the approximately 10V voltage to approximately 5V. That is, the first voltage conversion circuit is in buck mode. When the power adapter's output voltage is approximately 5V, the first voltage conversion circuit is used to directly output the approximately 5V voltage. 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 direct-through mode. It can be understood that the buck mode and direct-through mode of the first voltage conversion circuit can be achieved by controlling the on and off states of the switch in the first voltage conversion circuit. The direct-through mode of the first voltage conversion circuit generates less heat than the buck mode.

[0069] For example, combining Figure 3 and Figure 4 As shown, in a scenario where the electronic device is charging with the screen on, the power adapter's output voltage can be around 5V. The first voltage conversion circuit is controlled in direct-through mode, ensuring its output voltage matches the input voltage. The approximately 5V output from the first voltage conversion circuit is then transmitted through the first wired charging line to charge the electronic device's battery. Since the direct-through mode of the first voltage conversion circuit generates less heat than the buck mode, setting the power adapter's output voltage to around 5V and controlling the first voltage conversion circuit in direct-through mode can further improve the charging speed in a screen-on charging scenario.

[0070] For example, combining Figure 3 and Figure 4 As shown, in the scenario of charging an electronic device with the screen off, the output voltage of the power adapter can be around 10V. The first voltage conversion circuit is controlled to step-down mode, so that the output voltage of the first voltage conversion circuit is less than the input voltage. The voltage of around 5V output by the first voltage conversion circuit is then transmitted through the first wired charging line to charge the battery of the electronic device.

[0071] In this application embodiment, the output voltage of the power adapter is not limited to whether the electronic device is charging with the screen on or off; the above is merely an illustrative example. For instance, in the scenario of charging the electronic device with the screen on, the output voltage of the power adapter can also be around 10V. The first voltage conversion circuit is controlled in buck mode, so that the output voltage of the first voltage conversion circuit is less than the input voltage. The approximately 5V output voltage of the first voltage conversion circuit is then transmitted through the first wired charging line to charge the battery of the electronic device. That is, when the electronic device is wired charging, the output voltage of the power adapter can be the same regardless of whether the charging scenario is on or off.

[0072] The aforementioned configuration of the first wired charging line and the wireless charging coil may include: the first wired charging line reusing the wireless charging coil, or the first wired charging line not reusing the wireless charging coil.

[0073] When the first wired charging line reuses the wireless charging coil, the corresponding arrangement of the first wired charging line and the wireless charging coil can include the following three implementation methods.

[0074] In the first implementation, a first wired charging line is configured to correspond with a wireless charging coil, including: the first wired charging line being at least a part of the wireless charging coil.

[0075] When the first wired charging line is at least a part of the wireless charging coil, the first wired charging line reuses at least a part of the wireless charging coil. For example, the first wired charging line may reuse a part of the outermost coil of the wireless charging coil, or it may reuse at least a part of one coil of the wireless charging coil, or it may reuse multiple coils of the wireless charging coil. The embodiments of this application are not limited in this respect, and are merely illustrative examples.

[0076] When the first wired charging line is part of the outermost coil of the wireless charging coil (i.e., the first wired charging line reuses the outermost coil of the wireless charging coil), the first wired charging line is one. For example, as Figure 3 As shown in (a), the first wired charging line reuses the outermost coil of the wireless charging coil, and the first wired charging line is a single line. The first end of the first wired charging line is coupled to the output of the first voltage conversion circuit, and the second end of the first wired charging line is coupled to the battery of the electronic device.

[0077] When the first wired charging line includes at least a portion of a turn of the wireless charging coil (i.e., the first wired charging line reuses at least a portion of a turn of the wireless charging coil), there can be two first wired charging lines connected in parallel, one of which is at least a portion of a turn of the wireless charging coil. For example, as Figure 3 As shown in (b), the first wired charging line reuses at least a portion of a coil in the wireless charging coil, and there can be two first wired charging lines connected in parallel.

[0078] Optionally, when the first wired charging line is at least a part of the wireless charging coil, the first wired charging line may reuse at least a part of the outermost turn of the wireless charging coil, or at least a part of the innermost turn of the wireless charging coil, or at least a part of the middle turn of the wireless charging coil. This application embodiment does not limit this aspect. Figure 3 The following is an example of reusing at least a portion of the outermost turn of the wireless charging coil in the first wired charging line. It can be understood that when the first wired charging line reuses the wireless charging coil, reusing at least a portion of the outermost turn of the wireless charging coil can reduce the process difficulty compared to reusing at least a portion of the innermost turn or at least a portion of the middle turn of the wireless charging coil.

[0079] The second implementation method involves a first wired charging line corresponding to a wireless charging coil, including: the first wired charging line being at least a portion of the outermost turn of the wireless charging coil.

[0080] When the first wired charging line is at least a portion of the outermost turn of the wireless charging coil, the first wired charging line reuses at least a portion of the outermost turn of the wireless charging coil. For example, the first wired charging line can reuse a portion of the outermost turn of the wireless charging coil, or it can reuse at least a portion of the outermost turn of the wireless charging coil. This application embodiment is not limited in this respect, and it is only an illustrative example. It is understood that when the first wired charging line is a portion of the outermost turn of the wireless charging coil, there can be two first wired charging lines, and the two first wired charging lines are connected in parallel.

[0081] In the third implementation, the wireless charging coil includes a first layer coil and a second layer coil in the direction perpendicular to the screen of the electronic device, and a first wired charging line is correspondingly arranged with the wireless charging coil, including: the first wired charging line is at least a part of the outermost turn of the first layer coil.

[0082] When the first wired charging line is at least a portion of the outermost turn of the first layer coil, the first wired charging line reuses at least a portion of the outermost turn of the first layer coil of the wireless charging coil. For example, the first wired charging line may reuse a portion of the outermost turn of the first layer coil, or it may reuse at least a portion of the outermost turn of the first layer coil. This application embodiment is not limited in this respect, and is only an exemplary description.

[0083] Optionally, the first layer of coil can be the layer of coil closest to the screen of the electronic device among the multiple layers of coils included in the wireless charging coil.

[0084] When the first wired charging line reuses the wireless charging coil, the first wired charging line can be one or multiple lines, and this application embodiment does not limit this.

[0085] Understandable. Figure 3 The electronic devices shown are Figure 1 Compared to the electronic device shown, the elimination of the charging FPC allows for a larger space to accommodate the wireless charging coil. The increased size of the wireless charging coil reduces the path impedance of the wired charging circuit when the first wired charging line reuses the wireless charging coil, thereby improving the charging speed of the electronic device. This is especially noticeable in scenarios where the screen is on while charging, significantly increasing the charging speed.

[0086] Optionally, if the first wired charging line reuses the wireless charging coil, the wired charging circuit may further include a first switch and a second switch. A first end of the first wired charging line is coupled to the output of a first voltage conversion circuit via the first switch, and the input of the first voltage conversion circuit is used for coupling with a power adapter. A second end of the first wired charging line is coupled to the battery of the electronic device via the second switch. When the electronic device is wirelessly charging, the first and second switches are in the off state. When the electronic device is wired charging, the first and second switches are in the on state.

[0087] Optionally, there can be one or more second switches. The specific number of second switches is related to the number of first wired charging lines. When there is one first wired charging line, there is one second switch. When there are multiple first wired charging lines, there are multiple second switches, and these multiple first wired charging lines are connected in parallel. The second end of each first wired charging line is coupled to the battery of the electronic device through a second switch. When there are multiple first wired charging lines, there can also be one second switch, and the second ends of multiple first wired charging lines are all coupled to the battery of the electronic device through this second switch. The following embodiments illustrate the case where there are multiple first wired charging lines and multiple second switches.

[0088] The specific number of the aforementioned first wired charging lines is related to the way the first wired charging lines reuse the wireless charging coil. For example, when the first wired charging line reuses a portion of the outermost coil of the wireless charging coil, there can be one first wired charging line. As another example, when the first wired charging line reuses at least a portion of the outermost coil of the wireless charging coil, there can be two first wired charging lines, and these two first wired charging lines can be connected in parallel. In this embodiment, the specific number of the first wired charging lines when reusing the wireless charging coil is not limited; this is merely an illustrative example.

[0089] For example, taking a portion of the outermost coil of the wireless charging coil reused in the first wired charging line as an example, such as... Figure 3 As shown in (a), the first switch is S1, the second switch is S2, there is one first wired charging line, and one second switch S2. The first end of the first wired charging line is coupled to the output of the first voltage conversion circuit through S1, and the second end of the first wired charging line is coupled to the battery of the electronic device through S2.

[0090] For example, taking at least a portion of the outermost coil of the wireless charging coil reused in the first wired charging line as an example, such as... Figure 3As shown in (b), the first switch is S1, the second switch is S2, there can be two first 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 of the first voltage conversion circuit through S1. The second end of each first wired charging line is coupled to the battery of the electronic device through a switch.

[0091] like Figure 3 (a) and Figure 3 As shown in (b), when the electronic device is wired charging, switches S1 and S2 are in the ON state. The current output from the power adapter passes through the first voltage conversion circuit in the electronic device and then through the first wired charging line to power the battery of the electronic device. When the electronic device is wirelessly charging, S1 and S2 are in the OFF state. The coil in the wireless charger and the wireless charging coil in the electronic device generate electromagnetic induction. The induced current is rectified by the rectifier circuit, and then the HVSC chip converts the voltage of about 20V to about 10V. Then, the second voltage conversion circuit converts the voltage of about 10V to about 5V before powering the battery of the electronic device.

[0092] The embodiments of this application do not limit the specific number of the first switch and the second switch. Figure 3 In (a), the first switch is considered as one unit, and the second switch is considered as one unit. Figure 3 Example (b) illustrates the case where there is one first switch and two second switches. In practical applications, the number of first switches can also be multiple.

[0093] In the embodiments of this application, the first switch and the second switch can be metal-oxide-semiconductor field-effect transistors (MOSFETs, or MOS transistors for short) or insulated-gate bipolar transistors (IGBTs), and the embodiments of this application are not limited in this regard. When the first switch and the second switch are MOSFETs, they can be N-type MOSFETs or P-type MOSFETs.

[0094] Understandably, when the wireless charging coil is reused in the first wired charging circuit, the high voltage generated on the wireless charging coil during wireless charging may affect the battery and components in the wired charging circuit, potentially causing component failure. Therefore, this application addresses this by incorporating a first switch and a second switch in the wired charging circuit, and by turning off both switches during wireless charging. This prevents the voltage generated on the wireless charging coil from affecting components in the wired charging circuit and the battery of the electronic device, thus improving the reliability of charging. During wired charging, since the wired charging voltage is DC while the rectifier circuit's driving voltage is AC, wired charging does not affect the wireless charging circuit. Furthermore, by incorporating the first and second switches in the wired charging circuit, the portion of the wireless charging coil reused by the first wired charging circuit can be used for both wireless and wired charging.

[0095] When the first wired charging line does not reuse the wireless charging coil, the first wired charging line is configured to correspond with the wireless charging coil, including: the first wired charging line is configured along the outline of the wireless charging coil; the first wired charging line is not electrically connected to the wireless charging coil; and the first wired charging line configured to correspond with the wireless charging coil is only used for wired charging and not for wireless charging; that is: when the electronic device is wirelessly charged, the first wired charging line configured to correspond with the wireless charging coil has no wireless charging signal and no wireless charging current.

[0096] 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 its outline. The number of first wired charging lines arranged along the outline of the wireless charging coil can be one or more, and this embodiment does not limit this. When there are multiple first wired charging lines, these multiple first wired charging lines are connected in parallel.

[0097] For example, such as Figure 3 As shown in (c), the first wired charging line is not electrically connected to the wireless charging coil, and the first wired charging coil has a half-turn coil arranged around the wireless charging coil along the outline of the wireless charging coil. The first wired charging line is a single line, and its first end is used to couple to the power adapter through a first voltage conversion circuit, and its second end is coupled to the battery of the electronic device.

[0098] For example, such as Figure 3As shown in (d), the first wired charging line is not electrically connected to the wireless charging coil, and the first wired charging coil has a coil of one turn arranged around the wireless charging coil along the outline of the wireless charging coil. There are two first wired charging lines, which are connected in parallel.

[0099] Optionally, when the first wired charging line does not reuse the wireless charging coil, if the wireless charging line includes a first layer coil and a second layer coil, the first wired charging line can be arranged along the outline of the first layer coil. It is understood that by arranging the first wired charging line along the outline of the first layer coil, the impact on the size of the wireless charging coil caused by setting the first wired charging line can be reduced without changing the size of the electronic device.

[0100] When the first wired charging circuit does not reuse the wireless charging coil, the electronic device can support scenarios where wired and wireless charging coexist. For example, as Figure 3 (c) and Figure 3 The electronic device shown in (d) can support simultaneous wired and wireless charging.

[0101] Optionally, when the first wired charging line is not electrically connected to the wireless charging coil, the number of turns of the wireless charging coil can be reduced by one or half a turn, and the first wired charging line can be set at the position where one or half a turn is reduced. For example, taking a wireless charging coil in an electronic device that includes a 10-turn coil as an example, when the first wired charging line is not electrically connected to the wireless charging coil, the number of turns of the wireless charging coil can be reduced by one to a 9-turn coil, and a coil is set around the wireless charging coil along the outline of the wireless charging coil. This one-turn coil is the first wired charging line for wired charging.

[0102] Optionally, when the first wired charging line is not electrically connected to the wireless charging coil, an additional turn or half-turn coil can be provided along the outline of the wireless charging coil. This turn or half-turn coil serves as the first wired charging line for wired charging. For example, taking a wireless charging coil in an electronic device that includes 10 turns as an example, when the first wired charging line is not electrically connected to the wireless charging coil, an additional turn of coil can be provided around the wireless charging coil along its outline. This turn of coil serves as the first wired charging line for wired charging.

[0103] 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.

[0104] Understandable. Figure 3 The electronic devices shown are Figure 1Compared to the illustrated electronic device, by omitting the charging FPC in the electronic device, the first wired charging line can be made larger or wider, reducing the path impedance of the wired charging circuit and improving the charging speed of the electronic device with the screen on. Furthermore, in this embodiment, during wired charging, the charging current can flow directly from the port of the first wired charging line into the battery of the electronic device, bypassing the second voltage conversion circuit in the motherboard. This reduces heat generation on the motherboard and further improves the charging speed of the electronic device. Figure 3 The illustrated electronic device, especially in scenarios where the screen is on while charging, can significantly improve the charging speed. Furthermore, in this embodiment, when the wireless charging coil is reused in the first wired charging circuit, by setting a first switch and a second switch, it is possible to prevent the voltage generated on the wireless charging coil from affecting the components in the wired charging circuit and the battery of the electronic device during wireless charging.

[0105] The second circuit structure: as follows Figure 5 As shown, the wired charging circuit also includes a first voltage conversion circuit connected in series with the first wired charging line, a second wired charging line and a second voltage conversion circuit connected in series, and the first wired charging line and the first voltage conversion circuit connected in series are connected in parallel with the second wired charging line and the second voltage conversion circuit connected in series. When the electronic device is wired charged, it is charged through the first wired charging line and the second wired charging line.

[0106] Optionally, there can be one or more second voltage conversion circuits (e.g., two). When there are multiple second voltage conversion circuits, they are connected in parallel. The first end of the second wired charging line is coupled to the input end of the first voltage conversion circuit, and the second end of the second wired charging line is coupled to the battery of the electronic device through the multiple second voltage conversion circuits. Figure 5 The second voltage conversion circuit is used as an example for illustration.

[0107] Figure 6 This is a schematic diagram illustrating the charging principle of an electronic device. (Combined with...) Figure 5 ,like Figure 6As shown, during wired charging of the electronic device, one current from the power adapter passes through the first voltage conversion circuit in the electronic device, then through the first wired charging line to power the battery of the electronic device. The other current from the power adapter passes through the second wired charging line in the electronic device, then through the second voltage conversion circuit to power the battery of the electronic device. During wireless charging of the electronic device, the coil in the wireless charger and the wireless charging coil in the electronic device undergo electromagnetic induction. The resulting induced current is rectified by a rectifier circuit, and then the HVSC chip converts the approximately 20V voltage to approximately 10V. The second voltage conversion circuit then converts the approximately 10V voltage to approximately 5V before powering the battery of the electronic device. In other words, during wired charging of the electronic device, the first and second wired charging lines work together to charge the battery of the electronic device.

[0108] Optionally, the second wired charging line in this embodiment of the application can be... Figure 1 The charging FPC shown.

[0109] In this embodiment, when the electronic device is wired charged, the battery is charged through both the first and second wired charging lines, which can disperse the heat generated by the electronic device. Moreover, by charging the battery through two wired charging lines simultaneously, the path impedance can be reduced in scenarios where the screen is on, thereby improving the charging speed of the electronic device, especially in scenarios where the screen is on, the charging speed can be significantly improved.

[0110] Optionally, when the electronic device is wired charging, the power adapter's output voltage can be approximately 10V or approximately 5V. When the power adapter's output voltage is approximately 10V, the first and second voltage conversion circuits work together to convert the approximately 10V voltage to approximately 5V. That is, the first and second voltage conversion circuits operate in buck mode. When the power adapter's output voltage is approximately 5V, the first and second voltage conversion circuits are used to directly output the approximately 5V voltage. That is, the output voltage of the first voltage conversion circuit is the same as the input voltage, and the output voltage of the second voltage conversion circuit is the same as the input voltage; the first and second voltage conversion circuits operate in direct-through mode.

[0111] For example, combining Figure 5 and Figure 6As shown, in a scenario where the electronic device is charging with the screen on, the power adapter's output voltage can be around 5V. The first and second voltage conversion circuits are controlled in direct-through mode, ensuring that the output voltage of both circuits is the same as the input voltage. The approximately 5V output from the first voltage conversion circuit is transmitted through the first wired charging line to charge the electronic device's battery. Similarly, the approximately 5V output from the second wired charging line is directly output through the second voltage conversion circuit to charge the electronic device's battery. Since the direct-through mode of the voltage conversion circuit generates less heat than the buck mode, setting the power adapter's output voltage to around 5V and controlling the first and second voltage conversion circuits in direct-through mode in a screen-on charging scenario can further reduce the electronic device's heat generation and improve the charging speed.

[0112] For example, combining Figure 5 and Figure 6 As shown, in a scenario where the electronic device is charging with the screen off, the power adapter's output voltage can be around 10V. The first and second voltage conversion circuits are controlled in buck mode, ensuring that the output voltage of both circuits is lower than their input voltages. The approximately 5V output from the first voltage conversion circuit is transmitted through the first wired charging line to charge the electronic device's battery. Similarly, the approximately 10V output from the second wired charging line is stepped down by the second voltage conversion circuit and then used to charge the electronic device's battery.

[0113] In this application embodiment, the output voltage of the power adapter is not limited to whether the electronic device is charging with the screen on or off; the above is merely an illustrative example. For instance, in the scenario of charging with the screen on, the output voltage of the power adapter can be around 10V, controlling the first voltage conversion circuit and the second voltage conversion circuit to step-down mode. That is, when the electronic device is wired charging, the output voltage of the power adapter can be the same regardless of whether the charging scenario is on or off.

[0114] Figure 5 The first wired charging line may or may not reuse the wireless charging coil. When the first wired charging line reuses the wireless charging coil, the corresponding configuration of the first wired charging line and the wireless charging coil includes, but is not limited to: the first wired charging line being at least a part of the wireless charging coil, the first wired charging line being at least a part of the outermost turn of the wireless charging coil, and the first wired charging line being at least a part of the outermost turn of the first layer coil. For specific implementation details regarding the first wired charging line reusing the wireless charging coil, please refer to the relevant descriptions in the foregoing embodiments, which will not be repeated here.

[0115] In the case where the wireless charging coil is reused in the first wired charging line, the wired charging circuit may further include a first switch and a second switch. The number of the first and second switches, as well as their connection method, can be found in the previous embodiment and will not be repeated here.

[0116] When there are multiple wired charging lines, there may be one or more second switches, and this application does not limit this. The following embodiments illustrate this by taking the case where there are multiple wired charging lines and multiple second switches as an example.

[0117] For example, taking a portion of the outermost coil of the wireless charging coil reused in the first wired charging line as an example, such as... Figure 5 As shown in (a), the first switch is S1, the second switch is S2, the first wired charging line is one, and the second switch S2 is one. The first end of the first wired charging line is coupled to the output end of the first voltage conversion circuit through S1. The input end of the first voltage conversion circuit is used to couple to the power adapter. The second end of the first wired charging line is coupled to the battery of the electronic device through S2.

[0118] For example, taking at least a portion of the outermost coil of the wireless charging coil reused in the first wired charging line as an example, such as... Figure 5 As shown in (b), the first switch is S1, the second switch is S2, there are two first wired charging lines, and two second switches S2. The first ends of the two first wired charging lines are connected together and coupled to the output of the first voltage conversion circuit through S1. The second end of each first wired charging line is coupled to the battery of the electronic device through an S2.

[0119] like Figure 5 (a) and Figure 5 As shown in (b), during wired charging of the electronic device, S1 and S2 are in the on state. One current output from the power adapter passes through the first voltage conversion circuit in the electronic device and then through the first wired charging line to power the battery of the electronic device. The other current output from the power adapter passes through the second wired charging line in the electronic device and then through the second voltage conversion circuit to power the battery of the electronic device. During wireless charging of the electronic device, S1 and S2 are in the off state. The coil in the wireless charger and the wireless charging coil in the electronic device generate electromagnetic induction. The induced current is rectified by the rectifier circuit, and then the HVSC chip converts the voltage of about 20V to about 10V. Then, the second voltage conversion circuit converts the voltage of about 10V to about 5V before powering the battery of the electronic device.

[0120] The embodiments of this application do not limit the specific number of the first switch and the second switch. Figure 5 In (a), the first switch is considered as one unit, and the second switch is considered as one unit. Figure 5 Example (b) illustrates the case where there is one first switch and two second switches. In practical applications, the number of first switches can also be multiple.

[0121] Understandably, when the wireless charging coil is reused in the first wired charging circuit, the high voltage generated on the wireless charging coil during wireless charging may affect the battery and components in the wired charging circuit, potentially causing component failure. Therefore, this application addresses this by incorporating a first switch and a second switch in the wired charging circuit, and by turning off both switches during wireless charging. This prevents the voltage generated on the wireless charging coil from affecting the components in the wired charging circuit and the battery of the electronic device, thus improving the reliability of charging. Furthermore, by incorporating the first and second switches in the wired charging circuit, the portion of the wireless charging coil reused by the first wired charging circuit can be used for both wireless and wired charging.

[0122] When the first wired charging line does not reuse the wireless charging coil, the first wired charging line is configured correspondingly to the wireless charging coil, including: the first wired charging line is configured along the outline of the wireless charging coil, and the first wired charging line and the wireless charging coil are not electrically connected. When the first wired charging line does not reuse the wireless charging coil, the number of the first wired charging lines can be one or multiple, and this application embodiment is not limited in this respect.

[0123] For example, such as Figure 5 As shown in (c), the first wired charging line is not electrically connected to the wireless charging coil, and the first wired charging coil has a half-turn coil arranged around the wireless charging coil along the outline of the wireless charging coil.

[0124] For example, such as Figure 5 As shown in (d), the first wired charging line is not electrically connected to the wireless charging coil, and the first wired charging coil has a coil of one turn arranged around the wireless charging coil along the outline of the wireless charging coil. There are two first wired charging lines, which are connected in parallel.

[0125] When the first wired charging circuit does not reuse the wireless charging coil, the electronic device can support scenarios where wired and wireless charging coexist. For example, as Figure 5 (c) and Figure 5 The electronic device shown in (d) can support simultaneous wired and wireless charging.

[0126] Understandable. Figure 5 The electronic devices shown are Figure 1 Compared to the illustrated electronic device, by adding a first wired charging line corresponding to the wireless charging coil, both the first and second wired charging lines can simultaneously power the battery of the electronic device during wired charging. Connecting the two wired charging lines in parallel not only reduces path impedance but also evens out heat generation on the charging FPC, resulting in more uniform heat distribution and improved charging speed. Furthermore, when charging with the screen on, setting the power adapter's output voltage to approximately 5V and using a direct-flow mode for both the first and second voltage conversion circuits reduces motherboard heat generation and improves charging performance. Figure 5 The illustrated electronic device, especially in scenarios where the screen is on while charging, can significantly improve the charging speed. Furthermore, in this embodiment, when the wireless charging coil is reused in the first wired charging circuit, by setting a first switch and a second switch, it is possible to prevent the voltage generated on the wireless charging coil from affecting the components in the wired charging circuit and the battery of the electronic device during wireless charging, thereby improving the reliability of charging the electronic device.

[0127] The third type of circuit structure: such as Figure 7 As shown, the wired charging circuit also includes a second voltage conversion circuit connected in series with the first wired charging line. A first end of the first wired charging line is coupled to a power adapter, a second end of the first wired charging line is coupled to the input of the second voltage conversion circuit, and the output of the second voltage conversion circuit is coupled to the battery of the electronic device.

[0128] Optionally, there may be one or more second voltage conversion circuits (e.g., two). When there are multiple second voltage conversion circuits, they are connected in parallel, and the second end of the first wired charging line is coupled to the battery of the electronic device through each of the multiple second voltage conversion circuits. Figure 7 The second voltage conversion circuit is used as an example for illustration.

[0129] Figure 8 This is a schematic diagram illustrating the charging principle of an electronic device. (Combined with...) Figure 7 ,like Figure 8As shown, during wired charging of the electronic device, the current output from the power adapter is transmitted through the first wired charging line in the electronic device and then supplies power to the battery of the electronic device through the second voltage conversion circuit. During wireless charging of the electronic device, the coil in the wireless charger and the wireless charging coil in the electronic device undergo electromagnetic induction. The resulting induced current is rectified by the rectifier circuit, and then the HVSC chip converts the voltage of approximately 20V to approximately 10V. The second voltage conversion circuit then converts the approximately 10V voltage to approximately 5V before supplying power to the battery of the electronic device.

[0130] Optionally, when the electronic device is wired charged, the power adapter's output voltage can be approximately 10V or approximately 5V. When the power adapter's output voltage is approximately 10V, the second voltage conversion circuit converts the approximately 10V voltage to approximately 5V. That is, the second voltage conversion circuit operates in buck mode. When the power adapter's output voltage is approximately 5V, the second voltage conversion circuit directly outputs the approximately 5V voltage. That is, the output voltage of the second voltage conversion circuit is the same as the input voltage; the second voltage conversion circuit operates in direct mode.

[0131] For example, combining Figure 7 and Figure 8 As shown, in the scenario of charging an electronic device with the screen on, the power adapter's output voltage can be around 5V. The second voltage conversion circuit is controlled in pass-through mode, ensuring its output voltage matches the input voltage. The approximately 5V output from the power adapter is transmitted through the first wired charging line and then directly output through the second voltage conversion circuit to charge the electronic device's battery. Since the pass-through mode of the second voltage conversion circuit generates less heat than the buck mode, setting the power adapter's output voltage to around 5V and controlling the second voltage conversion circuit in pass-through mode in the scenario of charging with the screen on can further reduce the heat generated by the electronic device's motherboard and improve the charging speed.

[0132] For example, combining Figure 7 and Figure 8 As shown, in a scenario where the electronic device is charging with the screen off, the power adapter's output voltage can be around 10V. The second voltage conversion circuit is controlled in buck mode, making its output voltage lower than its input voltage. The approximately 10V output from the power adapter is transmitted through the first wired charging line and then stepped down by the second voltage conversion circuit to output approximately 5V, which is used to charge the electronic device's battery.

[0133] In this application embodiment, the output voltage of the power adapter is not limited to whether the electronic device is charging with the screen on or off; the above is merely an illustrative example. For instance, in the scenario of charging with the screen on, the output voltage of the power adapter can be around 10V. The second voltage conversion circuit is controlled in buck mode, so that the output voltage of the second voltage conversion circuit is less than the input voltage. The approximately 10V output voltage from the power adapter is transmitted through the first wired charging line and then stepped down by the second voltage conversion circuit to output approximately 5V, which is used to charge the battery of the electronic device. That is, when the electronic device is wired charging, the output voltage of the power adapter can be the same regardless of whether the charging scenario is on or off.

[0134] Figure 7 The first wired charging line may or may not reuse the wireless charging coil. When the first wired charging line reuses the wireless charging coil, the corresponding configuration of the first wired charging line and the wireless charging coil includes, but is not limited to: the first wired charging line being at least a part of the wireless charging coil, the first wired charging line being at least a part of the outermost turn of the wireless charging coil, and the first wired charging line being at least a part of the outermost turn of the first layer coil. For specific implementation details regarding the first wired charging line reusing the wireless charging coil, please refer to the relevant descriptions in the foregoing embodiments, which will not be repeated here.

[0135] When the first wired charging line reuses the wireless charging coil, the wired charging circuit may further include a first switch and a second switch. A first end of the first wired charging line is coupled to a power adapter via the first switch, and a second end of the first wired charging line is coupled to the input of a second voltage conversion circuit via the second switch. When the electronic device is wirelessly charging, both the first and second switches are in the off state. When the electronic device is wired charging, both the first and second switches are in the on state.

[0136] Optionally, there can be one or more second switches. The specific number of second switches is related to the number of first wired charging lines. When there are multiple first wired charging lines, there can be one or more second switches, and this embodiment of the application does not limit this. The following embodiments are exemplified by the case where there are multiple first wired charging lines and multiple second switches.

[0137] For example, taking a portion of the outermost coil of the wireless charging coil reused in the first wired charging line as an example, such as... Figure 7 As shown in (a), the first switch is S1, the second switch is S2, there is one first wired charging line, and one second switch S2. The first end of the first wired charging line is used to couple to the power adapter through S1, and the second end of the first wired charging line is coupled to the input end of the second voltage conversion circuit through S2.

[0138] For example, taking at least a portion of the outermost coil of the wireless charging coil reused in the first wired charging line as an example, such as... Figure 7 As shown in (b), the first switch is S1, the second switch is S2, there are two first wired charging lines, and two second switches S2. The first ends of the two first wired charging lines are connected together, and the first ends of the two first wired charging lines are used to couple to the power adapter through S1. The second end of each first wired charging line is coupled to the input terminal of the second voltage conversion circuit through an S2.

[0139] like Figure 7 (a) or Figure 7 In (b) of the diagram, when the electronic device is wired charging, S1 and S2 are in the on state. The current output by the power adapter is transmitted through the first wired charging line and then supplies power to the battery of the electronic device through the second voltage conversion circuit in the electronic device. When the electronic device is wirelessly charging, S1 and S2 are in the off state. The coil in the wireless charger and the wireless charging coil in the electronic device generate electromagnetic induction. The induced current is rectified by the rectifier circuit and then converted from approximately 20V to approximately 10V by the HVSC chip. The second voltage conversion circuit then converts the approximately 10V to approximately 5V before supplying power to the battery of the electronic device.

[0140] The embodiments of this application do not limit the specific number of the first switch and the second switch. Figure 7 In (a), the first switch is considered as one unit, and the second switch is considered as one unit. Figure 7 Example (b) is illustrated by taking the first switch as one and the second switch as two.

[0141] Understandably, when the wireless charging coil is reused in the first wired charging circuit, the high voltage generated on the wireless charging coil during wireless charging may affect the battery and components in the wired charging circuit, potentially causing component failure. Therefore, this application addresses this by incorporating a first switch and a second switch in the wired charging circuit, and by turning off both switches during wireless charging. This prevents the voltage generated on the wireless charging coil from affecting components in the wired charging circuit and the battery of the electronic device, thus improving the reliability of charging. Furthermore, by incorporating the first and second switches in the wired charging circuit, the portion of the wireless charging coil reused by the first wired charging circuit can be used for both wireless and wired charging.

[0142] When the first wired charging line does not reuse the wireless charging coil, the first wired charging line is configured correspondingly to the wireless charging coil, including: the first wired charging line is configured along the outline of the wireless charging coil, and the first wired charging line and the wireless charging coil are not electrically connected. When the first wired charging line does not reuse the wireless charging coil, the number of the first wired charging lines can be one or multiple, and this application embodiment is not limited in this respect.

[0143] For example, such as Figure 7 As shown in (c), the first wired charging line is not electrically connected to the wireless charging coil. The first wired charging coil has a half-turn coil arranged around the wireless charging coil along its outline. The first wired charging line is a single line. The first end of the first wired charging line is used for coupling connection with the power adapter, and the second end of the first wired charging line is coupled to the input terminal of the second voltage conversion circuit. The output terminal of the second voltage conversion circuit is coupled to the battery of the electronic device.

[0144] For example, such as Figure 7 As shown in (d), the first wired charging line is not electrically connected to the wireless charging coil. The first wired charging coil has one turn of coil around the wireless charging coil along its outline. There are two first wired charging lines connected in parallel. The first ends of the two first wired charging lines are coupled to a power adapter, and the second ends are coupled to the input of a second voltage conversion circuit. The output of the second voltage conversion circuit is coupled to the battery of the electronic device.

[0145] Understandable. Figure 7 The electronic devices shown are Figure 1 Compared to the illustrated electronic device, by omitting the charging FPC in the electronic device, the first wired charging line can be made larger or wider, reducing the path impedance of the wired charging circuit and improving the charging speed of the electronic device. Furthermore, in this embodiment, when the electronic device is charging with the screen on, the output voltage of the power adapter can be set to approximately 5V, and the second voltage conversion circuit can operate in direct-flow mode, further reducing the heat generated on the motherboard of the electronic device and improving the charging speed with the screen on. Figure 7 The illustrated electronic device, especially in scenarios where the screen is on while charging, can significantly improve the charging speed. Furthermore, in this embodiment, when the wireless charging coil is reused in the first wired charging circuit, by setting a first switch and a second switch, it is possible to prevent the voltage generated on the wireless charging coil from affecting the components in the wired charging circuit and the battery of the electronic device during wireless charging.

[0146] The fourth type of circuit structure: such as Figure 9As shown, the wired charging circuit also includes a second wired charging line connected in parallel with the first wired charging line, and a second voltage conversion circuit connected in series with the first and second wired charging lines. When the electronic device is wired charged, it is charged through the first and second wired charging lines.

[0147] Optionally, there may be one or more second voltage conversion circuits (e.g., two). When there are multiple second voltage conversion circuits, they are connected in parallel, and the second end of the first wired charging line is coupled to the battery of the electronic device through each of the multiple second voltage conversion circuits. Figure 9 The second voltage conversion circuit is used as an example for illustration.

[0148] Figure 10 This is a schematic diagram illustrating the charging principle of an electronic device. (Combined with...) Figure 9 ,like Figure 10 As shown, during wired charging of the electronic device, the current output from the power adapter passes through the first and second wired charging lines connected in parallel, and then through the second voltage conversion circuit to power the battery of the electronic device. During wireless charging, the coil in the wireless charger and the wireless charging coil in the electronic device induce an electromagnetic current. This induced current is rectified by a rectifier circuit, and then the HVSC chip converts the approximately 20V voltage to approximately 10V. The second voltage conversion circuit then converts the approximately 10V voltage to approximately 5V before powering the battery of the electronic device. In other words, during wired charging, the first and second wired charging lines work together to charge the battery of the electronic device.

[0149] Optionally, the second wired charging line in this embodiment of the application can be... Figure 1 The charging FPC shown.

[0150] In this embodiment, when the electronic device is wired charged, the battery is charged through both the first and second wired charging lines, which can disperse the heat generated by the electronic device. Moreover, by charging the battery through two wired charging lines simultaneously, the path impedance can be reduced in scenarios where the screen is on, thereby improving the charging speed of the electronic device, especially in scenarios where the screen is on, the charging speed can be significantly improved.

[0151] Optionally, when the electronic device is wired charged, the power adapter's output voltage can be approximately 10V or approximately 5V. When the power adapter's output voltage is approximately 10V, the second voltage conversion circuit converts the approximately 10V voltage to approximately 5V. That is, the second voltage conversion circuit operates in buck mode. When the power adapter's output voltage is approximately 5V, the second voltage conversion circuit directly outputs the approximately 5V voltage. That is, the output voltage of the second voltage conversion circuit is the same as the input voltage; the second voltage conversion circuit operates in direct mode.

[0152] For example, combining Figure 9 and Figure 10 As shown, in the scenario of charging an electronic device with the screen on, the power adapter's output voltage can be around 5V. The second voltage conversion circuit is controlled in direct-through mode, ensuring its output voltage matches the input voltage. The approximately 5V output from the power adapter is transmitted in parallel through the first and second wired charging lines, and then directly output through the second voltage conversion circuit to charge the electronic device's battery. Since the direct-through mode of the second voltage conversion circuit generates less heat than the buck mode, setting the power adapter's output voltage to around 5V and controlling the second voltage conversion circuit in direct-through mode in the scenario of charging with the screen on can further reduce the heat generated by the electronic device's motherboard and improve the charging speed.

[0153] For example, combining Figure 9 and Figure 10 As shown, in a scenario where the electronic device is charging with the screen off, the power adapter's output voltage can be around 10V. The second voltage conversion circuit is controlled in buck mode, making its output voltage lower than its input voltage. The approximately 10V output voltage from the power adapter is transmitted in parallel through the first and second wired charging lines, and then stepped down by the second voltage conversion circuit to output approximately 5V to charge the electronic device's battery.

[0154] In this application, the output voltage of the power adapter is not limited to whether the electronic device is charging with the screen on or off; the above is merely an illustrative example. For instance, in the scenario of charging with the screen on, the output voltage of the power adapter can be around 10V, controlling the second voltage conversion circuit to step-down mode. That is, when the electronic device is wired charging, the output voltage of the power adapter can be the same regardless of whether the charging scenario is on or off.

[0155] Figure 9The first wired charging line may or may not reuse the wireless charging coil. When the first wired charging line reuses the wireless charging coil, the corresponding configuration of the first wired charging line and the wireless charging coil includes, but is not limited to: the first wired charging line being at least a part of the wireless charging coil, the first wired charging line being at least a part of the outermost turn of the wireless charging coil, and the first wired charging line being at least a part of the outermost turn of the first layer coil. For specific implementation details regarding the first wired charging line reusing the wireless charging coil, please refer to the relevant descriptions in the foregoing embodiments, which will not be repeated here.

[0156] In the case where the wireless charging coil is reused in the first wired charging line, the wired charging circuit may further include a first switch and a second switch. The number of the first and second switches, as well as their connection method, can be found in the previous embodiment and will not be repeated here.

[0157] When there are multiple wired charging lines, there may be one or more second switches, and this application does not limit this. The following embodiments illustrate this by taking the case where there are multiple wired charging lines and multiple second switches as an example.

[0158] For example, taking a portion of the outermost coil of the wireless charging coil reused in the first wired charging line as an example, such as... Figure 9 As shown in (a), the first switch is S1, the second switch is S2, there is one first wired charging line, and one second switch S2. The first end of the first wired charging line is used to couple to the power adapter through S1, and the second end of the first wired charging line is coupled to the input end of the second voltage conversion circuit through S2.

[0159] For example, taking at least a portion of the outermost coil of the wireless charging coil reused in the first wired charging line as an example, such as... Figure 9 As shown in (b), the first switch is S1, the second switch is S2, there are two first wired charging lines, and two second switches S2. The first ends of the two first wired charging lines are connected together, and the first ends of the two first wired charging lines are used to couple to the power adapter through S1. The second end of each first wired charging line is coupled to the input terminal of the second voltage conversion circuit through an S2.

[0160] like Figure 9 (a) and Figure 9As shown in (b), when the electronic device is wired charging, S1 and S2 are in the on state. The current output by the power adapter is transmitted through the first and second wired charging lines connected in parallel, and then supplies power to the battery of the electronic device through the second voltage conversion circuit in the electronic device. When the electronic device is wirelessly charging, S1 and S2 are in the off state. The coil in the wireless charger and the wireless charging coil in the electronic device generate electromagnetic induction. The induced current is rectified by the rectifier circuit, and then the HVSC chip converts the voltage of about 20V to about 10V. Then, the second voltage conversion circuit converts the voltage of about 10V to about 5V before supplying power to the battery of the electronic device.

[0161] The embodiments of this application do not limit the specific number of the first switch and the second switch. Figure 9 In (a), the first switch is considered as one unit, and the second switch is considered as one unit. Figure 9 Example (b) illustrates the case where there is one first switch and two second switches. In practical applications, the number of first switches can also be multiple.

[0162] Understandably, when the wireless charging coil is reused in the first wired charging circuit, the high voltage generated on the wireless charging coil during wireless charging may affect the battery and components in the wired charging circuit, potentially causing component failure. Therefore, this application addresses this by incorporating a first switch and a second switch in the wired charging circuit, and by turning off both switches during wireless charging. This prevents the voltage generated on the wireless charging coil from affecting the components in the wired charging circuit and the battery of the electronic device, thus improving the reliability of charging. Furthermore, by incorporating the first and second switches in the wired charging circuit, the portion of the wireless charging coil reused by the first wired charging circuit can be used for both wireless and wired charging.

[0163] When the first wired charging line does not reuse the wireless charging coil, the first wired charging line is configured correspondingly to the wireless charging coil, including: the first wired charging line is configured along the outline of the wireless charging coil, and the first wired charging line and the wireless charging coil are not electrically connected. When the first wired charging line does not reuse the wireless charging coil, the number of the first wired charging lines can be one or multiple, and this application embodiment is not limited in this respect.

[0164] For example, such as Figure 9As shown in (c), the first wired charging line is not electrically connected to the wireless charging coil, and the first wired charging coil has a half-turn coil arranged around the wireless charging coil along the outline of the wireless charging coil. The first wired charging line is a single line, and its first end is used for coupling connection with the power adapter, while its second end is coupled to the input terminal of the second voltage conversion circuit.

[0165] For example, such as Figure 9 As shown in (d), the first wired charging line is not electrically connected to the wireless charging coil. The first wired charging coil has one turn of coil around the wireless charging coil along its outline. There are two first wired charging lines connected in parallel. The first ends of the two first wired charging lines are coupled to the power adapter, and the second ends of the two first wired charging lines are coupled to the input terminal of the second voltage conversion circuit.

[0166] Understandable. Figure 9 The electronic devices shown are Figure 1 Compared to the illustrated electronic device, by adding a first wired charging line corresponding to the wireless charging coil, both the first and second wired charging lines can simultaneously power the battery of the electronic device during wired charging. Connecting the two wired charging lines in parallel not only reduces path impedance but also evens out heat generation on the charging FPC, resulting in more uniform heat distribution and faster charging while the screen is on. Figure 9 The illustrated electronic device, especially in scenarios where the screen is on while charging, can significantly improve the charging speed. Furthermore, by setting the power adapter's output voltage to approximately 5V and using a direct-through mode for the second voltage conversion circuit during screen-on charging, the motherboard heat of the electronic device can be reduced, improving charging performance. Additionally, in this embodiment, where the wireless charging coil is reused in the first wired charging circuit, by setting a first switch and a second switch, the voltage generated on the wireless charging coil during wireless charging can be prevented from affecting components in the wired charging circuit and the battery of the electronic device, thus improving the reliability of charging.

[0167] This application also provides a control method for an electronic device, such as... Figure 11 As shown, the control method may include the following steps:

[0168] S1101. Detect the charging type of electronic devices.

[0169] Electronic devices can be charged using either wired or wireless methods.

[0170] In one implementation, 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 voltage conversion circuit and a first wired charging line connected in series, as well as a first switch and a second switch. The first wired charging line is correspondingly arranged with the wireless charging coil. A first end of the first wired charging line is coupled to the output end of the first voltage conversion circuit via the first switch. The input end of the first voltage conversion circuit is used for coupling connection with a power adapter, and a second end of the first wired charging line is coupled to the battery of the electronic device via the second switch. For example, the electronic device can be... Figure 3 (a) or Figure 3 The electronic device shown in (b) is shown in the image.

[0171] Optionally, the wired charging circuit in the electronic device may further include a second voltage conversion circuit and a second wired charging line connected in series, wherein the second voltage conversion circuit and the second wired charging line are connected in parallel with the first voltage conversion circuit and the first wired charging line connected in series. For example, the electronic device may be... Figure 5 (a) or Figure 5 The electronic device shown in (b) is shown in the image.

[0172] In another implementation, 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 line and a second voltage conversion circuit connected in series, as well as a first switch and a second switch. The first wired charging line is correspondingly arranged with the wireless charging coil. A first end of the first wired charging line is coupled to a power adapter via the first switch, and a second end of the first wired charging line is coupled to the input terminal of the second voltage conversion circuit via the second switch. The output terminal of the second voltage conversion circuit is coupled to the battery of the electronic device. For example, the electronic device can be... Figure 7 (a) or Figure 7 The electronic device shown in (b) is shown in the image.

[0173] Optionally, the wired charging circuit in the electronic device may further include a second wired charging circuit connected in parallel with the first wired charging circuit. The first and second wired charging circuits, after being connected in parallel, are then connected in series with the second voltage conversion circuit. For example, the electronic device can be... Figure 9 (a) or Figure 9 The electronic device shown in (b) is shown in the image.

[0174] In this embodiment, the corresponding arrangement of the first wired charging line and the wireless charging coil includes: the first wired charging line being at least a portion of the wireless charging coil; or, the first wired charging line being at least a portion of the outermost turn of the wireless charging coil; or, the first wired charging line being at least a portion of the outermost turn of the first layer coil. That is, in this embodiment, the first wired charging line reuses the wireless charging coil.

[0175] Optionally, if the electronic device is being wired charged while powered off, the charging type of the electronic device can be detected as wired charging when the power adapter is plugged into the charging port of the electronic device.

[0176] S1102. When the charging type of the electronic device is wireless charging, control the first switch and the second switch to turn off.

[0177] For example, using electronic devices as Figure 3 (a) Figure 3 (b) Figure 5 (a) Figure 5 (b) Figure 7 (a) Figure 7 (b) Figure 9 (a) or Figure 9 Taking any of the electronic devices shown in (b) as an example, when the charging type of the electronic device is wireless charging, the first switch S1 and the second switch S2 are turned off. The induced current generated by the wireless charging coil in the electronic device is rectified by the rectifier circuit, and then the voltage of about 20V is converted to about 10V by the HVSC chip. Then, the voltage of about 10V is converted to about 5V by the second voltage conversion circuit, and then the battery of the electronic device is powered.

[0178] In other words, when the charging type of the electronic device is wireless charging, the first and second switches are in the off state. Therefore, 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, which can improve the reliability of charging the electronic device.

[0179] S1103. When the charging type of the electronic device is wired charging, control the first switch and the second switch to be turned on.

[0180] Optionally, the default state of the first and second switches can be the off state.

[0181] For example, using electronic devices as Figure 3 (a) or Figure 3Taking the electronic device shown in (b) as an example, if the electronic device is powered on and undergoing wired charging, after detecting that the charging type of the electronic device is wired charging, the first switch S1 and the second switch S2 are turned on. The current output by the power adapter passes through the first voltage conversion circuit in the electronic device and then through the first wired charging line to supply power to the battery of the electronic device. If the battery of the electronic device is too low and it is powered off and undergoing wired charging, when the charging port of the electronic device is plugged into the power adapter, the first switch S1 and the second switch S2 can be turned on by the hardware circuit.

[0182] For example, taking electronic devices as an example Figure 5 (a) or Figure 5 Taking the electronic device shown in (b) as an example, if the electronic device is powered on and undergoing wired charging, after detecting that the charging type of the electronic device is wired charging, the first switch S1 and the second switch S2 are turned on. One current output from the power adapter passes through the first voltage conversion circuit in the electronic device and then through the first wired charging line to supply power to the battery of the electronic device. The other current output from the power adapter passes through the second wired charging line in the electronic device and then through the second voltage conversion circuit to supply power to the battery of the electronic device. If the battery of the electronic device is too low, and it is powered off and undergoing wired charging, the battery can be charged first through the second wired charging line. After the electronic device is powered on, when the charging type of the electronic device is detected as wired charging, the first switch S1 and the second switch S2 are turned on.

[0183] For example, taking electronic devices as an example Figure 7 (a) or Figure 7 Taking the electronic device shown in (b) as an example, when the charging type of the electronic device is wired charging, the first switch S1 and the second switch S2 are turned on. The current output by the power adapter is transmitted through the first wired charging line and then supplies power to the battery of the electronic device through the second voltage conversion circuit.

[0184] For example, taking electronic devices as an example Figure 9 (a) or Figure 9 Taking the electronic device shown in (b) as an example, when the charging type of the electronic device is wired charging, the first switch S1 and the second switch S2 are turned on. The current output by the power adapter is transmitted through the first wired charging line and the second wired charging line connected in parallel, and then supplies power to the battery of the electronic device through the second voltage conversion circuit in the electronic device.

[0185] Understandably, when the wireless charging coil is reused in the first wired charging line, by setting a first switch and a second switch on both sides of the first wired charging line respectively, and turning off the first and second switches when the electronic device is wirelessly charging, and turning on the first and second switches when the electronic device is wired charging, the wired charging of the electronic device will not affect the wireless charging, and vice versa. This can improve the charging speed of electronic devices (especially the charging speed when the screen is on) while improving the reliability of electronic device charging.

[0186] Optionally, in this application embodiment, when the electronic device is wired charging, it can distinguish between screen-on charging scenarios and screen-off charging scenarios, or it can not distinguish between screen-on charging scenarios and screen-off charging scenarios. If the electronic device is wired charging and the screen-on charging scenario and screen-off charging scenario are distinguished, the above control method may further include: detecting whether the charging scenario of the electronic device is screen-on charging or screen-off charging. When the electronic device is charging with the screen on and the charging type is wired charging, controlling the output voltage of the power adapter to a first voltage, and controlling the first voltage conversion circuit and / or the second voltage conversion circuit to a pass-through mode. When the electronic device is charging with the screen off and the charging type is wired charging, controlling the output voltage of the power adapter to a second voltage, and controlling the first voltage conversion circuit and / or the second voltage conversion circuit to a buck mode. The first voltage may be less than the second voltage.

[0187] For example, when an electronic device is charging via wired connection with the screen on, the power adapter's output voltage can be controlled to around 5V. When the electronic device is charging via wired connection with the screen off, the power adapter's output voltage can be controlled to around 10V. Combining the above... Figures 3 to 10 It is known that when the output voltage of the power adapter is around 5V, the first voltage conversion circuit and / or the second voltage conversion circuit are in direct mode to power the battery of the electronic device. Since the direct mode of the voltage conversion circuit has lower power consumption and less heat generation than the buck mode, it can further improve the charging speed of the electronic device with the screen on.

[0188] The steps of the methods or algorithms described in this application can be implemented in hardware or by a processor executing software instructions. The software instructions can consist of corresponding software modules, which can be stored in random access memory (RAM), flash memory, erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), registers, hard disks, portable hard disks, CD-ROMs, or any other form of storage medium known in the art. An exemplary storage medium is coupled to a processor, enabling the processor to read information from and write information to the storage medium. Of course, the storage medium can also be a component of the processor. The processor and storage medium can reside in an ASIC. Alternatively, the ASIC can reside in a core network interface device. Of course, the processor and storage medium can also exist as discrete components in the core network interface device.

[0189] Those skilled in the art will recognize that, in one or more of the examples above, the functions described in this invention can be implemented using hardware, software, firmware, or any combination thereof.
