[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0031] Electronic devices are connected to a power adapter and a device to be charged (such as a mobile phone or headphones), enabling the power adapter to simultaneously supply power to the battery inside the electronic device and the device to be charged. Then, when the power adapter is disconnected from the electronic device, the battery inside the electronic device can supply power to the device to be charged.

[0032] However, when the power adapter switches from simultaneously supplying power to both the battery in the electronic device and the device to be charged to the electronic device supplying power to the device to be charged, the device to be charged and the electronic device need to communicate again, which interrupts the charging process of the device to be charged.

[0033] The inventors of this application have discovered that a carrier can be designed, which may include: a first input terminal, a first output terminal, a functional chip, a first circuit, a second circuit, and connecting lines; the functional chip is signal-connected to the first input terminal and the first output terminal, and is at least used to transmit a request signal from the first output terminal to the first input terminal; the first circuit includes: a first voltage regulating module, which is signal-connected to the first input terminal and the functional chip, and has a second output terminal; the second circuit includes: a second voltage regulating module, which is signal-connected to the first input terminal, the first output terminal, and the functional chip, and is signal-connected to the first voltage regulating module via connecting lines. The first input terminal, the first output terminal, and the second output terminal can be respectively connected to a power adapter, a device to be charged, and a rechargeable battery. The device to be charged, connected to the first output terminal, can send a request signal to the functional chip. This request signal indicates the specific voltage required by the device. The functional chip can negotiate this request signal with the power adapter connected to the first input terminal, enabling the second voltage regulator module to obtain a DC voltage consistent with the requested voltage of the device. The second voltage regulator module converts this DC voltage into the charging voltage required by the device and charges the device through the first output terminal, while the first voltage regulator module obtains the required voltage. The first voltage regulator module converts the DC voltage, consistent with that of the rechargeable battery, into the charging voltage required by the rechargeable battery and charges it through the second output terminal, thus enabling simultaneous charging of the device to be charged and the rechargeable battery. Furthermore, when the power adapter is disconnected from the first input terminal, the second voltage regulator module, connected to the first voltage regulator module via a signal connection line, allows the second voltage regulator module to directly communicate with the first voltage regulator module at least when the received DC voltage decreases. This establishes a new charging path between the rechargeable battery, the first voltage regulator module, the second voltage regulator module, and the first output terminal, charging the device to be charged. Conversely, when there is no signal connection between the second and first voltage regulator modules, and the device to be charged does not receive voltage, it re-establishes communication with the rechargeable battery in the first circuit via a functional chip. This path is complex and long. Compared to this setup, the second voltage regulator module and the first voltage regulator module connected via a signal connection line in this application can quickly supply power from the power adapter to the rechargeable battery, thereby reducing the probability of charging interruptions due to power adapter disconnection.

[0034] First aspect

[0035] This disclosure provides a carrier 10, see [link to details]. Figure 1 and Figure 2As shown, the carrier 10 may include: a first input terminal 11, a first output terminal 12, a functional chip 13, a first circuit 14, and a second circuit 15; the functional chip 13 is signal-connected to the first input terminal 11 and the first output terminal 12, and is at least used to transmit the request signal of the first output terminal 12 to the first input terminal 11; the first circuit 14 includes: a first voltage regulating module 141, which is signal-connected to the first input terminal 11 and the functional chip 13, and has a second output terminal 142; the second circuit 15 includes: a second voltage regulating module 151, which is signal-connected to the first input terminal 11, the first output terminal 12, and the functional chip 13, and is signal-connected to the first voltage regulating module 141 through a connecting line 16.

[0036] The carrier 10 may also include a board on which the first input terminal 11, the first output terminal 12, the functional chip 13, the first circuit 14 and the second circuit 15 can all be disposed, so as to improve the integration of the carrier 10 and reduce the assembly efficiency when it is disposed in the electronic device 20.

[0037] The first input terminal 11 can be used to connect a power adapter 30, which can be connected to a power source and provide power to the first input terminal 11.

[0038] The first output terminal 12 can be used to connect to a mobile phone, tablet computer, laptop computer, or other charging device 40, and the first output terminal 12 can provide the electrical energy it receives to the charging device 40 to charge the charging device 40.

[0039] The functional chip 13 is signal-connected to the first input terminal 11 and the first output terminal 12, so that the functional chip 13 can send the requested voltage of the device to be charged 40 connected to the first output terminal 12 to the power adapter 30 connected to the first input terminal 11 through the first input terminal 11. This enables the functional chip 13 and the power adapter 30 connected to the first input terminal 11 to communicate via protocol, so that the first voltage regulating module 141 and the second voltage regulating module 151 can respectively receive DC voltages adapted to the corresponding device to be charged 40 and power adapter 30.

[0040] The first circuit 14 includes a first voltage regulating module 141 (DCDC1), which adjusts the DC voltage output from the first input terminal 11 to a voltage signal adapted to the rechargeable battery 22 connected to the second output terminal 142, so as to charge the rechargeable battery 22 and reduce the situation of providing overvoltage signals to the rechargeable battery 22.

[0041] The second circuit 15 includes a second voltage regulating module 151 (DCDC2). The second voltage regulating module 151 is used to adjust the DC voltage output from the first input terminal 11 to a voltage signal that is compatible with the device 40 to be charged connected to the first output terminal 12, so as to charge the device 40 to be charged and reduce the situation of providing overvoltage signals to the device 40 to be charged, so as to protect the device 40 to be charged.

[0042] The connecting line 16 can be an I2C bus (Inter-Integrated Circuit) or other wiring configurations that can signal connect the first voltage regulator module 141 and the second voltage regulator module 151.

[0043] See one example. Figure 2 As shown, the electronic device 20 may include: a housing 21, a rechargeable battery 22, and a carrier 10. The housing 21 has a first interface and a second interface exposed from the outside of the housing 21. The rechargeable battery 22 is disposed inside the housing 21. The carrier 10 is disposed inside the housing 21 and includes: a first input terminal 11, a first output terminal 12, a functional chip 13, a first circuit 14, and a second circuit 15. The first input terminal 11 is signal-connected to the first interface; the first output terminal 12 is signal-connected to the second interface; the functional chip 13 is signal-connected to the first input terminal 11 and the first output terminal 12, and... The first circuit 14 includes at least a first voltage regulating module 141, which is signal-connected to the first input terminal 11 and the functional chip 13, and has a second output terminal 142, which is signal-connected to the rechargeable battery 22. The second circuit 15 includes a second voltage regulating module 151, which is signal-connected to the first input terminal 11, the first output terminal 12 and the functional chip 13, and is signal-connected to the first voltage regulating module 141 via a connecting line 16. This electronic device 20 can be a power bank device.

[0044] In this embodiment, the carrier 10 may include: a first input terminal 11, a first output terminal 12, a functional chip 13, a first circuit 14, and a second circuit 15. The first input terminal 11 can be signal-connected to the power adapter 30, and the first output terminal 12 can be signal-connected to the charging device 40 (such as a mobile phone or tablet computer). The functional chip 13 is signal-connected to both the first input terminal 11 and the first output terminal 12. The first voltage regulating module 141 of the first circuit 14 is connected to the first input terminal 11 and has a second output terminal 142 connected to it. The second output terminal 142 can be signal-connected to the rechargeable battery 22. The second voltage regulating module 151 of the second circuit 15 is signal-connected to the first input terminal 11, the first output terminal 12, the functional chip 13, and the first voltage regulating module 141. The charging device 40, signal-connected to the first output terminal 12, can send a request signal to the functional chip 13. This request signal indicates the specific voltage required by the charging device. The functional chip 13 can negotiate and communicate with the power adapter 30 connected to the first input terminal 11, enabling the second voltage regulating module 151 to... 1. Obtaining a DC voltage consistent with the requested voltage of the device to be charged 40, the second voltage regulating module 151 converts the DC voltage into the charging voltage required by the device to be charged 40 and charges the device to be charged 40 through the first output terminal 12. Simultaneously, the first voltage regulating module 141 obtains a DC voltage consistent with the rechargeable battery 22, converts the DC voltage into the charging voltage required by the rechargeable battery 22 and charges the rechargeable battery 22 through the second output terminal 142. Thus, simultaneous charging of the device to be charged 40 and the rechargeable battery 22 is achieved. Furthermore, when the power adapter 30 is disconnected from the first input terminal 11, since the second voltage regulating module 151 and the first voltage regulating module 141 are signal-connected via the connecting line 16, the second voltage regulating module 151 can directly communicate and confirm with the first voltage regulating module 141 at least when the obtained DC voltage decreases. This allows the rechargeable battery 22, the first voltage regulating module 141, the second voltage regulating module 151, and the first output terminal 12 to form a new charging path and charge the device to be charged 40. When there is no signal connection between the second voltage regulating module 151 and the first voltage regulating module 141, and the device to be charged 40 does not receive voltage, the device to be charged 40 re-communicates with the rechargeable battery 22 of the first circuit 14 through the functional chip 13. The path formed by this method is complex and long. Compared with this setting, the second voltage regulating module 151 and the first voltage regulating module 141 are connected by the connection line 16 in this embodiment, which can quickly realize the power supply from the power adapter 30 to the rechargeable battery 22, thereby reducing the probability of the charging process being interrupted due to the disconnection of the power adapter 30 during the charging process of the device to be charged 40.

[0045] In some embodiments, see Figure 1 and Figure 2As shown, the functional chip 13 may include a first power delivery integrated circuit 131 (PDIC, Power Delivery Interface Controller) and a second power delivery integrated circuit 132 (PDIC, Power Delivery Interface Controller) connected by signals. The first power delivery integrated circuit 131 and the second power delivery integrated circuit 132 are respectively connected to the first input terminal 11 and the first output terminal 12. In this way, the power adapter 30 connected to the first input terminal 11 can communicate with the first power delivery integrated circuit 131 through a protocol, and the device to be charged 40 connected to the first output terminal 12 can communicate with the second power delivery integrated circuit 132 through a protocol.

[0046] In some embodiments, see Figure 1 and Figure 2 As shown, the first circuit 14 further includes: a first line 143, the input terminal of the first line 143 being signal-connected to the first input terminal 11, and the output terminal of the first line 143 being signal-connected to the first voltage regulating module 141; the second circuit 15 further includes: a second line 152, the input terminal of the second line 152 being signal-connected to the first input terminal 11, and the output terminal of the second line 152 being signal-connected to the second voltage regulating module 151; wherein, the second line 152 and the first line 143 are collinear at one end of the signal connection to the first input terminal 11, so that the second voltage regulating module 151, the second line 152, the first line 143 and the first voltage regulating module 141 are connected in sequence, and the second output terminal 142 forms the second input terminal.

[0047] In other words, the first input terminal 11 can charge the rechargeable battery 22 through the first line 143, the first voltage regulating module 141, and the second output terminal 142. The first input terminal 11 can charge the device 40 to be charged through the second line 152, the second voltage regulating module 151, and the first output terminal 12. When the power adapter 30 is disconnected from the first input terminal 11, the rechargeable battery 22 can charge the battery 40 to be charged through the second input terminal, the first line 143, the first voltage regulating module 141, the second voltage regulating module 151, and the first output terminal 12. The second input terminal and the second output terminal 142 are the same connection terminal to simplify the structural configuration of the carrier 10.

[0048] In some embodiments, the carrier 10 has a first voltage regulation state and a second voltage regulation state; in the first voltage regulation state, the first voltage regulation module 141 outputs a first voltage through the second output terminal 142, and the second voltage regulation module 151 outputs a second voltage to the first output terminal 12; in the second voltage regulation state, the first voltage regulation module 141 outputs the third voltage received at the second input terminal to the first output terminal 12 through the first line 143, the second line 152, and the second voltage regulation module 151. Alternatively, in the first voltage regulation state, the power adapter 30 simultaneously supplies power to the device to be charged 40 and the rechargeable battery 22; in the second voltage regulation state, the rechargeable battery 22 supplies power to the device to be charged 40.

[0049] In some embodiments, see Figure 2 As shown, the carrier 10 may further include a voltage detection device, which is signal-connected to the first input terminal 11, and switches the carrier 10 from a first voltage regulation state to a second voltage regulation state when a voltage drop is detected at the first input terminal 11. A voltage drop at the first input terminal 11 indicates that the power adapter 30 has disconnected from the first input terminal 11. Switching the carrier 10 from the first voltage regulation state to the second voltage regulation state based on this detection basis can further reduce the probability of charging interruption due to the disconnection of the power adapter 30 during the charging process of the device to be charged 40.

[0050] In some embodiments, see Figure 2 As shown, when the voltage detection device detects that the voltage at the first input terminal 11 has dropped to the target value, the carrier 10 switches from the first voltage regulation state to the second voltage regulation state.

[0051] The target value can be slightly less than the voltage when the power adapter 30 supplies power to both the device to be charged 40 and the rechargeable battery 22 at the same time, so that the second voltage regulating module 151 can communicate with the first voltage regulating module 141 in a shorter time, thereby further reducing the probability of the charging process being interrupted due to the disconnection of the power adapter 30 during the charging process of the device to be charged 40.

[0052] Second aspect

The first input terminal 11 is signal-connected to the first interface; the first output terminal 12 is signal-connected to the second interface; the functional chip 13 is signal-connected to the first input terminal 11 and the first output terminal 12, and... The circuit is at least used to transmit a request signal from the first output terminal 12 to the first input terminal 11; the first circuit 14 includes: a first voltage regulating module 141, which is signal-connected to the first input terminal 11 and the functional chip 13, and has a second output terminal 142, which is signal-connected to the rechargeable battery 22; the second circuit 15 includes: a second voltage regulating module 151, which is signal-connected to the first input terminal 11, the first output terminal 12 and the functional chip 13, and is signal-connected to the first voltage regulating module 141 through a connecting line 16.

This enables the functional chip 13 and the power adapter 30 connected to the first input terminal 11 to communicate via protocol, so that the first voltage regulating module 141 and the second voltage regulating module 151 can respectively receive DC voltages adapted to the corresponding device to be charged 40 and power adapter 30.

[0059] The first circuit 14 includes a first voltage regulating module 141, which adjusts the DC voltage output from the first input terminal 11 to a voltage signal adapted to the rechargeable battery 22 connected to the second output terminal 142, so as to charge the rechargeable battery 22 and reduce the situation of providing overvoltage signals to the rechargeable battery 22.

[0060] The second circuit 15 includes a second voltage regulating module 151. The second voltage regulating module 151 is used to adjust the DC voltage output from the first input terminal 11 to a voltage signal that is compatible with the device 40 to be charged connected to the first output terminal 12, so as to charge the device 40 to be charged and reduce the situation of providing overvoltage signals to the device 40 to be charged, so as to protect the device 40 to be charged.

The first circuit 14 includes at least a first voltage regulating module 141, which is signal-connected to the first input terminal 11 and the functional chip 13, and has a second output terminal 142, which is signal-connected to the rechargeable battery 22. The second circuit 15 includes a second voltage regulating module 151, which is signal-connected to the first input terminal 11, the first output terminal 12 and the functional chip 13, and is signal-connected to the first voltage regulating module 141 via a connecting line 16. This electronic device 20 can be a power bank device.

[0063] In this embodiment, the carrier 10 may include: a first input terminal 11, a first output terminal 12, a functional chip 13, a first circuit 14, and a second circuit 15. The first input terminal 11 can be signal-connected to the power adapter 30, and the first output terminal 12 can be signal-connected to the charging device 40 (such as a mobile phone or tablet computer). The functional chip 13 is signal-connected to both the first input terminal 11 and the first output terminal 12. The first voltage regulating module 141 of the first circuit 14 is connected to the first input terminal 11 and has a second output terminal 142 connected to it. The second output terminal 142 can be signal-connected to the rechargeable battery 22. The second voltage regulating module 151 of the second circuit 15 is signal-connected to the first input terminal 11, the first output terminal 12, the functional chip 13, and the first voltage regulating module 141. The charging device 40, signal-connected to the first output terminal 12, can send a request signal to the functional chip 13. This request signal indicates the specific voltage required by the charging device. The functional chip 13 can negotiate and communicate with the power adapter 30 connected to the first input terminal 11, enabling the second voltage regulating module 151 to... 1. Obtaining a DC voltage consistent with the requested voltage of the device to be charged 40, the second voltage regulating module 151 converts the DC voltage into the charging voltage required by the device to be charged 40 and charges the device to be charged 40 through the first output terminal 12. Simultaneously, the first voltage regulating module 141 obtains a DC voltage consistent with the rechargeable battery 22, converts the DC voltage into the charging voltage required by the rechargeable battery 22 and charges the rechargeable battery 22 through the second output terminal 142. Thus, simultaneous charging of the device to be charged 40 and the rechargeable battery 22 is achieved. Furthermore, when the power adapter 30 is disconnected from the first input terminal 11, since the second voltage regulating module 151 and the first voltage regulating module 141 are signal-connected via the connecting line 16, the second voltage regulating module 151 can directly communicate and confirm with the first voltage regulating module 141 at least when the obtained DC voltage decreases. This allows the rechargeable battery 22, the first voltage regulating module 141, the second voltage regulating module 151, and the first output terminal 12 to form a new charging path and charge the device to be charged 40. When there is no signal connection between the second voltage regulating module 151 and the first voltage regulating module 141, and the device to be charged 40 does not receive voltage, the device to be charged 40 re-communicates with the rechargeable battery 22 of the first circuit 14 through the functional chip 13. The path formed by this method is complex and long. Compared with this setting, the second voltage regulating module 151 and the first voltage regulating module 141 are connected by the connection line 16 in this embodiment, which can quickly realize the power supply from the power adapter 30 to the rechargeable battery 22, thereby reducing the probability of the charging process being interrupted due to the disconnection of the power adapter 30 during the charging process of the device to be charged 40.

[0064] In some embodiments, see Figure 1 and Figure 2As shown, the functional chip 13 may include a first power delivery integrated circuit 131 (PDIC, Power Delivery Interface Controller) and a second power delivery integrated circuit 132 (PDIC, Power Delivery Interface Controller) connected by signals. The first power delivery integrated circuit 131 and the second power delivery integrated circuit 132 are respectively connected to the first input terminal 11 and the first output terminal 12. In this way, the power adapter 30 connected to the first input terminal 11 can communicate with the first power delivery integrated circuit 131 through a protocol, and the device to be charged 40 connected to the first output terminal 12 can communicate with the second power delivery integrated circuit 132 through a protocol.

[0065] In some embodiments, see Figure 1 and Figure 2 As shown, the first circuit 14 further includes: a first line 143, the input terminal of the first line 143 being signal-connected to the first input terminal 11, and the output terminal of the first line 143 being signal-connected to the first voltage regulating module 141; the second circuit 15 further includes: a second line 152, the input terminal of the second line 152 being signal-connected to the first input terminal 11, and the output terminal of the second line 152 being signal-connected to the second voltage regulating module 151; wherein, the second line 152 and the first line 143 are collinear at one end of the signal connection to the first input terminal 11, so that the second voltage regulating module 151, the second line 152, the first line 143 and the first voltage regulating module 141 are connected in sequence, and the second output terminal 142 forms the second input terminal.

[0066] In other words, the first input terminal 11 can charge the rechargeable battery 22 through the first line 143, the first voltage regulating module 141, and the second output terminal 142. The first input terminal 11 can charge the device 40 to be charged through the second line 152, the second voltage regulating module 151, and the first output terminal 12. When the power adapter 30 is disconnected from the first input terminal 11, the rechargeable battery 22 can charge the battery 40 to be charged through the second input terminal, the first line 143, the first voltage regulating module 141, the second voltage regulating module 151, and the first output terminal 12. The second input terminal and the second output terminal 142 are the same connection terminal to simplify the structural configuration of the carrier 10.

[0067] In some embodiments, the carrier 10 has a first voltage regulation state and a second voltage regulation state; in the first voltage regulation state, the first voltage regulation module 141 outputs a first voltage through the second output terminal 142, and the second voltage regulation module 151 outputs a second voltage to the first output terminal 12; in the second voltage regulation state, the first voltage regulation module 141 outputs the third voltage received at the second input terminal to the first output terminal 12 through the first line 143, the second line 152, and the second voltage regulation module 151. Alternatively, in the first voltage regulation state, the power adapter 30 simultaneously supplies power to the device to be charged 40 and the rechargeable battery 22; in the second voltage regulation state, the rechargeable battery 22 supplies power to the device to be charged 40.

[0068] In some embodiments, see Figure 2 As shown, the carrier 10 may further include a voltage detection device, which is signal-connected to the first input terminal 11, and switches the carrier 10 from a first voltage regulation state to a second voltage regulation state when a voltage drop is detected at the first input terminal 11. A voltage drop at the first input terminal 11 indicates that the power adapter 30 has disconnected from the first input terminal 11. Switching the carrier 10 from the first voltage regulation state to the second voltage regulation state based on this detection basis can further reduce the probability of charging interruption due to the disconnection of the power adapter 30 during the charging process of the device to be charged 40.

[0069] In some embodiments, see Figure 2 As shown, when the voltage detection device detects that the voltage at the first input terminal 11 has dropped to the target value, the carrier 10 switches from the first voltage regulation state to the second voltage regulation state.

[0070] The target value can be slightly less than the voltage when the power adapter 30 supplies power to both the device to be charged 40 and the rechargeable battery 22 at the same time, so that the second voltage regulating module 151 can communicate with the first voltage regulating module 141 in a shorter time, thereby further reducing the probability of the charging process being interrupted due to the disconnection of the power adapter 30 during the charging process of the device to be charged 40.
