Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a charging device 100 provided in an embodiment of this application.

[0024] Please see Figure 1 The charging device 100 includes a power interface 110, a first charging circuit 120, a second charging circuit 130, and a battery 140.

[0025] The first charging circuit 120 is connected to the power interface 110 and the battery 140, and the second charging circuit 130 is also connected to the power interface 110 and the battery 140.

[0026] When the power interface 110 is connected to a power source, the first charging circuit 120 and the second charging circuit 130 together charge the battery 140.

[0027] In some implementations, the power interface 110 can be used to connect a power source.

[0028] For example, the power interface 110 may include a Universal Serial Bus (USB) interface, a Direct Current (DC) power interface, an Alternating Current (AC) power interface, etc., without limitation. The USB interface may include a USB Type-A interface, a USB Type-B interface, and a USB Type-C interface. The USB Type-A interface is also referred to as a Type-A interface, the USB Type-B interface as a Type-B interface, and the USB Type-C interface as a Type-C interface.

[0029] For example, the charging device 100 may include a charging case, such as a glasses charging case, an earphone charging case, a wristband charging case, a combined glasses and earphone charging case, a combined earphone and wristband charging case, etc. Correspondingly, the battery 140 may include a charging case battery, such as a glasses charging case battery, an earphone charging case battery, a wristband charging case battery, a combined glasses and earphone charging case battery, a combined earphone and wristband charging case battery, etc. Of course, the charging device 100 and the battery 140 are not limited to these, and no limitation is made here.

[0030] For example, the power interface 110 can be connected to a power source via a power adapter, so that the first charging circuit 120 and the second charging circuit 130 can use the power source to charge the battery 140 together.

[0031] like Figure 2 As shown, taking a Type-C interface as an example, the Type-C interface can be connected to a power adapter, and the power adapter can be connected to a power source. Therefore, the Type-C interface can be connected to a power source via the power adapter. The power adapter may include, for example, a 5V adapter, and is not limited here. When the Type-C interface is connected to a power source via the power adapter, since the first charging circuit 120 is connected to both the power interface 110 and the battery 140, the first charging circuit 120 can use the power supplied by the power source to charge the battery 140. Correspondingly, since the second charging circuit 130 is connected to both the power interface 110 and the battery 140, the second charging circuit 130 can also use the power supplied by the power source to charge the battery 140. Based on this, the first charging circuit 120 and the second charging circuit 130 can jointly charge the battery 140 when the power interface 110 is connected to a power source.

[0032] Of course, the connection between the power interface 110 and the first charging circuit 120 and the second charging circuit 130 is not limited to this. For example, the power interface 110 can be communicatively connected to the first charging circuit 120 and the second charging circuit 130. For instance, the power interface 110 may be provided with pins for data transmission. The power interface 110 can be connected to the first charging circuit 120 and the second charging circuit 130 through these data transmission pins to establish a communication connection between the power interface 110 and the first charging circuit 120 and the second charging circuit 130. Figure 2As shown, taking power interface 110 as a Type-C interface, the first charging circuit 120 includes a first charging chip U1, and the second charging circuit 130 includes a second charging chip U2 as an example. The Type-C interface has pins for data transmission, such as D+, D-, SBU1, and SBU2. The D+ pin is also called the DP pin, and the D- pin is also called the DN pin. The first charging chip U1 can have pins for data transmission, such as CLK1 and DAT1. Correspondingly, the second charging chip U2 can also have pins for data transmission, such as CLK2 and DAT2. The Type-C interface can connect to the CLK1 pin of the first charging chip U1 via the D+ pin and to the DAT1 pin of the first charging chip U1 via the D- pin. The Type-C interface can connect to the CLK2 pin of the second charging chip U2 via the SBU1 pin and to the DAT2 pin of the second charging chip U2 via the SBU2 pin.

[0033] Based on the communication connection between the power interface 110 and the first charging circuit 120 and the second charging circuit 130, the power interface 110 can be used to realize communication and interaction functions with the first charging circuit 120 and the second charging circuit 130, such as the programming function. For example, based on the communication connection between the power interface 110 and the first charging circuit 120 and the second charging circuit 130, the power interface 110 can realize the acquisition and reading of information related to the first charging circuit 120 and the second charging circuit 130, and can also realize the editing and writing of information related to the first charging circuit 120 and the second charging circuit 130, which is conducive to improving the convenience of the charging device 100 in controlling the first charging circuit 120 and the second charging circuit 130.

[0034] When the charging device 100 charges the battery 140 using the power supplied by the power source connected to the power interface 110 through the first charging circuit 120 and the second charging circuit 130, dual charging of the battery 140 can be achieved. In this dual charging scenario, both the first charging circuit 120 and the second charging circuit 130 can provide a corresponding charging current to the battery 140, which helps improve the charging efficiency of the charging device 100. For example, if the maximum charging current provided by each of the first charging circuit 120 and the second charging circuit 130 to the battery 140 is 1A, when both circuits charge the battery 140 together, the maximum charging current provided can reach 2A, further improving the charging efficiency. Correspondingly, since both the first charging circuit 120 and the second charging circuit 130 are connected to the power interface 110 and the battery 140, they are essentially two charging circuits connected in parallel. Compared to a single first charging circuit 120 or a single second charging circuit 130, the internal resistance of the parallel first charging circuit 120 and the second charging circuit 130 is reduced. Therefore, compared to charging the battery 140 through a single first charging circuit 120 or a single second charging circuit 130, charging the battery 140 through the parallel first charging circuit 120 and the second charging circuit 130 together helps to reduce the heat generated during the charging process, thereby improving the charging safety of the battery 140 of the charging device 100.

[0035] Please see Figure 1 The first charging circuit 120 is also used to connect to the first electronic device 200 so as to charge the first electronic device 200 through the first charging circuit 120.

[0036] The second charging circuit 130 is also used to connect to the second electronic device 300 so as to charge the second electronic device 300 through the second charging circuit 130.

[0037] For example, the first electronic device 200 may include at least one of headphones, a speaker, a near-eye display device, and a wearable device. The second electronic device 300 may include at least one of headphones, a speaker, a near-eye display device, and a wearable device.

[0038] For example, near-eye display devices can include augmented reality (AR) devices, virtual reality (VR) devices, and mixed reality (MR) devices. AR devices can include AR glasses and AR headsets. VR devices can include VR glasses and VR headsets. MR devices can include MR glasses and MR headsets. Wearable devices can include smartwatches, smart bracelets, and smart rings.

[0039] Of course, the first electronic device 200 and the second electronic device 300 are not limited to this. For example, the first electronic device 200 and the second electronic device 300 also include other devices with charging needs, which are not limited here.

[0040] The number of first electronic devices 200 may include one or more, and the number of second electronic devices 300 may include one or more. Correspondingly, the number of first charging circuits 120 may include one or more, and the number of second charging circuits 130 may also include one or more, without limitation.

[0041] The first electronic device 200 and the second electronic device 300 may include different devices of the same type, or they may include different devices of different types.

[0042] For example, if the first electronic device 200 is a pair of headphones and the second electronic device 300 is another pair of headphones, then both the first electronic device 200 and the second electronic device 300 are headphones, and therefore they are different devices of the same type. Of course, this is not a limitation; for example, the first electronic device 200 could be AR glasses, and the second electronic device 300 could be VR glasses, etc., etc., without further restriction.

[0043] For example, if the first electronic device 200 is a headset and the second electronic device 300 is a near-eye display device, then the first electronic device 200 and the second electronic device 300 are different types of devices. Of course, this is not a limitation; for example, the first electronic device 200 could be a speaker and the second electronic device 300 could be a wearable device. Or, for example, the first electronic device 200 could be a headset and the second electronic device 300 could be a speaker, and so on, without further limitation.

[0044] Both the first charging circuit 120 and the second charging circuit 130 can have load detection capabilities. The first charging circuit 120 can detect whether a first electronic device 200 is connected to the first charging circuit 120, and the second charging circuit 130 can detect whether a second electronic device 300 is connected to the second charging circuit 130. When the first electronic device 200 is connected to the first charging circuit 120, the charging device 100 can charge the first electronic device 200 through the first charging circuit 120. Similarly, when the second electronic device 300 is connected to the second charging circuit 130, the charging device 100 can charge the second electronic device 300 through the second charging circuit 130. The charging device 100 can also charge the battery 140 simultaneously through both the first charging circuit 120 and the second charging circuit 130, thus enabling the charging device 100 to charge the battery 140, the first electronic device 200, and the second electronic device 300 simultaneously.

[0045] The charging device 100 may have power monitoring capabilities. For example, during the charging process of the charging device 100 charging at least one of the battery 140, the first electronic device 200, and the second electronic device 300, the charging device 100 may monitor in real time whether the power of at least one of the battery 140, the first electronic device 200, and the second electronic device 300 is at full charge, in order to determine whether to continue charging at least one of the battery 140, the first electronic device 200, and the second electronic device 300.

[0046] For example, when the charging device 100 detects that the battery 140 is fully charged, but the first electronic device 200 and the second electronic device 300 are not fully charged, the charging device 100 can charge the first electronic device 200 through the first charging circuit 120 and charge the second electronic device 300 through the second charging circuit 130, and stop charging the battery 140 through both the first charging circuit 120 and the second charging circuit 130.

[0047] When the charging device 100 detects that the battery 140 and the first electronic device 200 are both fully charged, but the second electronic device 300 is not fully charged, the charging device 100 can charge the second electronic device 300 only through the second charging circuit 130, stopping the charging of the battery 140 through both the first charging circuit 120 and the second charging circuit 130, and stopping the charging of the first electronic device 200 through the first charging circuit 120. For example, the charging device 100 can boost the voltage of the second charging circuit 130 corresponding to the second electronic device 300 to enter a constant voltage charging state, so that the charging device 100 can charge the second electronic device 300 only through the second charging circuit 130.

[0048] When the charging device 100 detects that the circuits of the battery 140 and the second electronic device 300 are fully charged, but the circuit of the first electronic device 200 is not fully charged, the charging device 100 can charge the first electronic device 200 only through the first charging circuit 120, and stop charging the battery 140 through the first charging circuit 120 and the second charging circuit 130, and stop charging the second electronic device 300 through the second charging circuit 130. For example, the charging device 100 can boost the voltage of the first charging circuit 120 corresponding to the first electronic device 200 to enter a constant voltage charging state, so that the charging device 100 can charge the first electronic device 200 only through the first charging circuit 120.

[0049] Taking an example where the charging device 100 includes a glasses charging case, the battery 140 includes a glasses charging case battery, the first electronic device 200 includes smart glasses, and the second electronic device 300 includes headphones, the smart glasses can include AR glasses, VR glasses, etc., and are not limited here. The glasses charging case can be connected to the smart glasses through the first charging circuit 120 and to the headphones through the second charging circuit 130, thus enabling the glasses charging case battery, smart glasses, and headphones to charge. Accordingly, during the charging process, the glasses charging case can monitor in real time whether the glasses charging case battery, smart glasses, and headphones are fully charged to determine whether to continue charging the glasses charging case battery, smart glasses, or headphones. Of course, the charging device 100, battery 140, first electronic device 200, and second electronic device 300 are not limited to this, and are not limited here.

[0050] In one exemplary embodiment, when the first charging circuit 120 is connected to the first electronic device 200, if the power interface 110 is connected to a power source, the first charging circuit 120 can use the power from the power source connected to the power interface 110 to charge the first electronic device 200. When the second charging circuit 130 is connected to the second electronic device 300, if the power interface 110 is connected to a power source, the second charging circuit 130 can use the power from the power source connected to the power interface 110 to charge the second electronic device 300. Accordingly, the first charging circuit 120 and the second charging circuit 130 can jointly charge the battery 140 using the power from the power source connected to the power interface 110.

[0051] In another exemplary embodiment, when the first charging circuit 120 is connected to the first electronic device 200, if the power interface 110 is not connected to a power source, the first charging circuit 120 can use the power from the battery 140 to charge the first electronic device 200. When the second charging circuit 130 is connected to the second electronic device 300, if the power interface 110 is not connected to a power source, the second charging circuit 130 can use the power from the battery 140 to charge the second electronic device 300.

[0052] For example, the first charging circuit 120 includes a first charging chip U1. The second charging circuit 130 includes a second charging chip U2. The first charging chip U1 and the second charging chip U2 may include chips integrating power management, a microcontroller unit (MCU), and charge / discharge control. Of course, the first charging chip U1 and the second charging chip U2 may also integrate other functions, which is not limited here. For example, the first charging chip U1 and the second charging chip U2 are preferably IP5528 or IP5529. The first charging chip U1 and the second charging chip U2 may include chips of the same model or different models, which is not limited here.

[0053] The first charging chip U1 can be connected to the power interface 110, the battery 140, and the first electronic device 200 through different pins. The second charging chip U2 can be connected to the power interface 110, the battery 140, and the second electronic device 300 through different pins.

[0054] Taking the first charging chip U1 and the second charging chip U2 as examples, both of which include a first pin, a second pin, a third pin, and a fourth pin.

[0055] The first pin can be used to indicate the charging input pins of the first charging chip U1 and the second charging chip U2 respectively. The first charging chip U1 can be connected to the power interface 110 through its first pin. The second charging chip U2 can be connected to the power interface 110 through its first pin. For example... Figure 2 As shown, the first pin may include the VIN1 pin of the first charging chip U1 and the VIN2 pin of the second charging chip U2. The first charging chip U1 can be connected to the power interface 110 through the VIN1 pin, and the second charging chip U2 can be connected to the power interface 110 through the VIN2 pin. Of course, the first pin is not limited to this, and no limitation is made here.

[0056] The second pin can be used to indicate the first output pins of the first charging chip U1 and the second charging chip U2 respectively. The first charging chip U1 can be connected to the battery 140 through its second pin. The second charging chip U2 can be connected to the battery 140 through its second pin. Figure 2 As shown, the second pin may include the LX1 pin of the first charging chip U1 and the LX2 pin of the second charging chip U2. The first charging chip U1 can be connected to the battery 140 through the LX1 pin, and the second charging chip U2 can be connected to the battery 140 through the LX2 pin. Of course, the second pin is not limited to this, and no limitation is made here.

[0057] Both the third and fourth pins can be used to indicate the second output pins of the first charging chip U1 and the second charging chip U2, respectively. The first charging chip U1 can be connected to the first electronic device 200 through at least one of its third and fourth pins. The second charging chip U2 can be connected to the second electronic device 300 through at least one of its third and fourth pins. For example... Figure 2 As shown, the third pin may include the VPHL1 pin of the first charging chip U1 and the VPHL2 pin of the second charging chip U2, and the fourth pin may include the VPHR1 pin of the first charging chip U1 and the VPHR2 pin of the second charging chip U2. The first charging chip U1 can be connected to the first electronic device 200 through at least one of the VPHL1 and VPHR1 pins, and the second charging chip U2 can be connected to the second electronic device 300 through at least one of the VPHL2 and VPHR2 pins.

[0058] For example, the first electronic device 200 and the second electronic device 300 can be configured in pairs. For instance, if the first electronic device 200 is a pair of earphones and the second electronic device 300 is another pair of earphones, each pair includes a left earphone and a right earphone. Based on this, the first charging chip U1 can be connected to the left earphone in one pair via the VPHL1 pin and to the right earphone in another pair via the VPHR1 pin. Correspondingly, the second charging chip U2 can also be connected to the left earphone in another pair via the VPHL2 pin and to the right earphone in another pair via the VPHR2 pin.

[0059] Of course, the third and fourth pins are not limited to these, and no restrictions are imposed here.

[0060] like Figure 2 As shown, the first charging chip U1 is connected to the power interface 110 via the VIN1 pin, to the battery 140 via the LX1 pin, and to the first electronic device 200 via at least one of the VPHL1 and VPHR1 pins. If the power interface 110 is connected to a power source, the first charging chip U1 can use the power supplied by the power source connected to the power interface 110 to charge the battery 140 and the first electronic device 200. If the power interface 110 is not connected to a power source, the first charging chip U1 can use the power from the battery 140 to charge the first electronic device 200.

[0061] like Figure 2As shown, the second charging chip U2 is connected to the power interface 110 via the VIN2 pin, to the battery 140 via the LX2 pin, and to the second electronic device 300 via at least one of the VPHL2 and VPHR2 pins. If the power interface 110 is connected to a power source, the second charging chip U2 can use the power supplied by the power source connected to the power interface 110 to charge the battery 140 and the second electronic device 300. If the power interface 110 is not connected to a power source, the second charging chip U2 can use the power from the battery 140 to charge the second electronic device 300.

[0062] Please combine Figure 2 See Figure 3 Taking the first charging chip U1 and the second charging chip U2 as examples, which include chips of the same model, the first charging chip U1 and the second charging chip U2 can be collectively referred to as charging chips. The VIN1 pin of the first charging chip U1 and the VIN2 pin of the second charging chip U2 can be collectively referred to as the VIN pin of the charging chip. The LX1 pin of the first charging chip U1 and the LX2 pin of the second charging chip U2 can be collectively referred to as the LX pin of the charging chip. The VPHL1 pin of the first charging chip U1 and the VPHL2 pin of the second charging chip U2 can be collectively referred to as the VPHL pin of the charging chip. The VPHR1 pin of the first charging chip U1 and the VPHR2 pin of the second charging chip U2 can be collectively referred to as the VPHR pin of the charging chip.

[0063] like Figure 3As shown, within the charging chip, the VIN pin and LX pin are connected. For example, the VIN pin of the charging chip is connected to the power interface 110 of the charging device 100, and the VIN pin is connected to the LX pin of the charging chip through the internal circuitry. The LX pin of the charging chip is connected to the battery 140 of the charging chip. In an exemplary embodiment, the VIN pin of the charging chip is connected to the LX pin of the charging chip through an overvoltage protection (OVP) transistor, a P-channel metal-oxide-semiconductor (PMOS) transistor, and an N-type metal-oxide-semiconductor (NMOS) transistor. When the power interface 110 is connected to a power source, the VIN pin and LX pin of the charging chip can be connected through internal circuitry to implement a direct current (DC) to DC step-down function to charge the battery 140. For example, when power interface 110 is connected to a power source and the OVP transistor is in the ON state, the charging current provided by the power source can flow sequentially through the VIN pin of the charging chip, the OVP transistor, the PMOS transistor, the LX pin, and the battery 140. The charging chip can then use the power provided by the power source connected to power interface 110 to charge the battery 140. When the charging chip includes a first charging chip U1 and a second charging chip U2, dual charging of the battery 140 can be achieved.

[0064] like Figure 3As shown, externally, the VOUT pin of the charging chip is connected to the VOUTS pin. Internally, the VOUT pin is connected to the LX pin to achieve a boost function, and the VOUTS pin is connected to the VPHL and VPHR pins respectively. For example, the VOUT pin is connected between the OVP transistor and the PMOS transistor. The VOUTS pin is connected to the VPHL and VPHR pins through a low dropout regulator (LDO) circuit to achieve a current limiting function. The VPHL and VPHR pins of the charging chip can be used to connect electronic devices, such as a first electronic device 200 or a second electronic device 300. When the power interface 110 is connected to a power source, the OVP transistor is in the ON state. The charging current provided by the power source can sequentially pass through the VIN pin, OVP transistor, VOUT pin, VOUTS pin, LDO circuit, and VPHL pin of the charging chip to charge the electronic device connected to the VPHL pin. Correspondingly, when the power interface 110 is connected to a power source, the charging current provided by the power source can also sequentially pass through the VIN pin, OVP transistor, VOUT pin, VOUTS pin, LDO circuit, and VPHR pin to charge the electronic device connected to the VPHR pin. For example, if the charging chip includes a first charging chip U1 and a second charging chip U2, at least one of the VPHL1 and VPHR1 pins of the first charging chip U1 is connected to the first electronic device 200, such as a pair of headphones. At least one of the VPHL2 and VPHR2 pins of the second charging chip U2 is connected to the second electronic device 300, such as AR glasses. Of course, it is not limited to this, and no restrictions are set here.

[0065] Therefore, when the power interface 110 of the charging device 100 is connected to a power source, if the first charging circuit 120 is connected to the battery 140 and the first electronic device 200, and the second charging circuit 130 is connected to the battery 140 and the second electronic device 300, then the first charging circuit 120 and the second charging circuit 130 can charge the battery 140 simultaneously, while the first charging circuit 120 can charge the first electronic device 200, and the second charging circuit 130 can charge the second electronic device 300. Conversely, if the first charging circuit 120 is not connected to the first electronic device 200, and the second charging circuit 130 is connected to the second electronic device 300, then the first charging circuit 120 and the second charging circuit 130 can charge the battery 140 simultaneously, while the second charging circuit 130 can charge the second electronic device 300. And so on.

[0066] like Figure 3As shown, when the VIN pin of the charging chip is connected to the power interface 110 and the power interface 110 is not connected to a power source, the charging current provided by the battery 140 of the charging device 100 can sequentially pass through at least one of the LX pin, PMOS transistor, VOUT pin, VOUTS pin, LDO circuit, VPHL pin, and VPHR pin of the charging chip to charge the electronic device connected to at least one of the VPHL pin and VPHR pin.

[0067] Therefore, when the power interface 110 of the charging device 100 is not connected to a power source, since both the first charging circuit 120 and the second charging circuit 130 are connected to the battery 140, the first charging circuit 120 can use the power of the battery 140 to charge the first electronic device 200 when the first charging circuit 120 is connected to it. Similarly, when the second charging circuit 130 is connected to the second electronic device 300, the second charging circuit 130 can use the power of the battery 140 to charge the second electronic device 300.

[0068] In one exemplary embodiment, taking the power interface 110 as a Type-C interface, the first charging circuit 120 includes a first charging chip U1, and the second charging circuit 130 includes a second charging chip U2 as an example. Please refer to... Figure 2 See Figure 4A ,like Figure 4A As shown, the DP pin of the Type-C interface is connected to one end of resistor R5, and the other end of resistor R5 is connected to the CLK1 pin of the first charging chip U1. The DN pin of the Type-C interface is connected to one end of resistor R6, and the other end of resistor R6 is connected to the DAT1 pin of the first charging chip U1. The SBU1 pin of the Type-C interface is connected to one end of resistor R4, and the other end of resistor R4 is connected to the CLK2 pin of the second charging chip U2. The SBU2 pin of the Type-C interface is connected to one end of resistor R7, and the other end of resistor R7 is connected to the DAT2 pin of the second charging chip U2. The VBUS1 and VBUS2 pins of the Type-C interface can be used as VBUS pins of the Type-C interface, connected to the VIN1 pin of the first charging chip U1 and the VIN2 pin of the second charging chip U2, respectively. Therefore, when the Type-C interface is connected to a power source, the Type-C interface can provide power to the first charging chip U1 and the second charging chip U2 through the VBUS pins. Among them, resistors R4 to R7 can include zero-ohm resistors, which are not limited here.

[0069] like Figure 4BAs shown, the LX pin of the first charging chip U1 can be used as the LX1 pin. The LX1 pin of the first charging chip U1 is connected to one end of the inductor L1, and the other end of the inductor L1 is connected to one end of the resistor R8. The other end of the resistor R8 can be used as the VBAT pin of the first charging chip U1. The VBAT pin of the first charging chip U1 can be connected to the battery 140. However, this is not limited to this; the VBAT pin of the first charging chip U1 can also be connected to the CSIN pin, BAT pin, etc., of the first charging chip U1. At least one of the VPHL1 pin and VPHR1 pin of the first charging chip U1 can be used to connect to the first electronic device 200. When the Type-C interface provides power to the first charging chip U1 and the second charging chip U2 through the VBUS pin, the first charging chip U1 can charge the battery 140 through the VBAT pin corresponding to the LX1 pin. Correspondingly, the first charging chip U1 can charge the first electronic device 200 through at least one of the VPHL1 pin and VPHR1 pin.

[0070] like Figure 4C As shown, the LX pin of the second charging chip U2 can be used as the LX2 pin. The LX2 pin of the second charging chip U2 is connected to one end of the inductor L2, and the other end of the inductor L2 is connected to one end of the resistor R29. The other end of the resistor R29 can be used as the VBAT pin of the second charging chip U2. The VBAT pin of the second charging chip U2 can be connected to the battery 140. However, this is not limited to this; the VBAT pin of the second charging chip U2 can also be connected to the CSIN pin, BAT pin, etc., of the second charging chip U2. At least one of the VPHL2 pin and VPHR2 pin of the second charging chip U2 can be used to connect to the second electronic device 300. When the Type-C interface provides power to the first charging chip U1 and the second charging chip U2 through the VBUS pin, the second charging chip U2 can charge the battery 140 through the VBAT pin corresponding to the LX1 pin of the second charging chip U2. Correspondingly, the second charging chip U2 can charge the second electronic device 300 through at least one of the VPHL2 pin and VPHR2 pin.

[0071] With the first charging circuit 120 connected to the power interface 110 and the battery 140, and the second charging circuit 130 also connected to the power interface 110 and the battery 140, and the first charging circuit 120 further connected to the first electronic device 200, and the second charging circuit 130 further connected to the second electronic device 300, the first charging circuit 120 can charge at least one of the battery 140 and the first electronic device 200, and the second charging circuit 130 can charge at least one of the battery 140 and the second electronic device 300. Therefore, the charging device 100 can be used to charge at least one of the battery 140, the first electronic device 200, and the second electronic device 300, thereby improving the flexibility of use of the charging device 100. When the charging device 100 can be connected to the first electronic device 200 via the first charging circuit 120 and to the second electronic device 300 via the second charging circuit 130, the charging device 100 is equivalent to having multiple charging interfaces. Accordingly, as the number of first charging circuits 120 and second charging circuits 130 included in the charging device 100 increases, the charging device 100 can expand to have more charging interfaces to charge more first electronic devices 200 and second electronic devices 300, which is beneficial to improving the convenience of charging electronic devices. When the charging device 100 includes first charging circuits 120 and second charging circuits 130, it is beneficial to improve the integration of the charging device 100, thereby reducing the hardware cost of the charging device 100.

[0072] In some embodiments, the charging device 100 is provided with a first receiving portion and a second receiving portion.

[0073] The first receiving portion is used to receive the first electronic device 200, and the first receiving portion is provided with a first connecting portion, which is connected to the first charging circuit 120 and is used to connect to the first electronic device 200 on the first receiving portion.

[0074] The second receiving portion is used to receive the second electronic device 300, and a second connecting portion is provided on the second receiving portion. The second connecting portion is connected to the second charging circuit 130, and the second connecting portion is used to connect to the second electronic device 300 on the second receiving portion.

[0075] The first charging circuit 120 is used to charge the first electronic device 200 on the first receiving part through the first connecting part, and the second charging circuit 130 is used to charge the second electronic device 300 on the second receiving part through the second connecting part.

[0076] The first charging circuit 120 of the charging device 100 may have a load detection function. For example, the first charging circuit 120 may detect whether a first electronic device 200 is connected to the first connecting part based on the connection relationship between the first charging circuit 120 and the first connecting part. When the first charging circuit 120 detects that a first electronic device 200 is connected to the first connecting part, the charging device 100 may determine that the first electronic device 200 is housed in the first receiving part. Accordingly, the charging device 100 may determine that the first electronic device 200 needs to be charged, and the first charging circuit 120 of the charging device 100 may charge the first electronic device 200 in the first receiving part through the first connecting part.

[0077] The second charging circuit 130 of the charging device 100 may also have a load detection function. For example, the second charging circuit 130 can detect whether a second electronic device 300 is connected to the second connecting part based on the connection relationship between the second charging circuit 130 and the second connecting part. When the second charging circuit 130 detects that a second electronic device 300 is connected to the second connecting part, the charging device 100 can determine that the second electronic device 300 is housed in the second receiving part. Accordingly, the charging device 100 can determine that the second electronic device 300 needs to be charged, and the second charging circuit 130 of the charging device 100 can charge the second electronic device 300 in the first receiving part through the second connecting part.

[0078] Taking a first charging circuit 120 including a first charging chip U1 and a second charging circuit 130 including a second charging chip U2 as an example, the first connecting portion provided on the first receiving portion of the charging device 100 can be connected to at least one of the VPHL1 pin and VPHR1 pin of the first charging chip U1. The second connecting portion provided on the second receiving portion of the charging device 100 can be connected to at least one of the VPHL2 pin and VPHR2 pin of the second charging chip U2.

[0079] In one exemplary embodiment, during the process of placing the first electronic device 200 into the first receiving portion of the charging device 100, the first connecting portion can establish a contact connection with the first electronic device 200. Then, the first charging circuit 120 can perform contact charging on the first electronic device 200 through the contact connection between the first connecting portion and the first electronic device 200. For example, if both the first electronic device 200 and the first connecting portion are designed with metal contacts, then when the metal contacts of the first electronic device 200 contact the metal contacts of the first connecting portion, the first charging circuit 120 can charge the first electronic device 200 through the first connecting portion. As another example, the first electronic device 200 can be designed with metal contacts, and the first connecting portion can be designed as a spring contact or spring pin corresponding to the metal contacts of the first electronic device 200. Then, when the metal contacts of the first electronic device 200 contact the spring contact or spring pin of the first connecting portion, the first charging circuit 120 can charge the first electronic device 200 through the first connecting portion. Similarly, during the process of placing the second electronic device 300 into the second receiving portion of the charging device 100, the second connecting portion can also establish a contact connection with the second electronic device 300. Then, the second charging circuit 130 can perform contact charging on the second electronic device 300 through the contact connection between the second connecting portion and the second electronic device 300.

[0080] In another exemplary embodiment, during the process of placing the first electronic device 200 into the first receiving portion of the charging device 100, the first connecting portion can establish a contactless connection with the first electronic device 200. Then, the first charging circuit 120 can perform contactless charging of the first electronic device 200 through the contactless connection between the first connecting portion and the first electronic device 200. For example, the first charging circuit 120 can charge the first electronic device 200 using the principle of electromagnetic induction through the first connecting portion. Similarly, during the process of placing the second electronic device 300 into the second receiving portion of the charging device 100, the second connecting portion can also establish a contactless connection with the second electronic device 300. Then, the second charging circuit 130 can perform contactless charging of the second electronic device 300 through the contactless connection between the second connecting portion and the second electronic device 300.

[0081] Accordingly, the charging device 100 is provided with a first receiving portion and a second receiving portion, so that the first electronic device 200 is received by the first receiving portion and the second electronic device 300 is received by the second receiving portion. This allows the charging device 100 to both charge the first electronic device 200 and the second electronic device 300, and also to receive them, thus improving the portability of the first electronic device 200 and the second electronic device 300. For example, by receiving the first electronic device 200 in the first receiving portion and the second electronic device 300 in the second receiving portion of the charging device 100, both the first electronic device 200 and the second electronic device 300 can be carried while carrying the charging device 100.

[0082] The arrangement of the first and second accommodating portions on the charging device 100 improves the portability of both the first electronic device 200 and the second electronic device. The arrangement of the first accommodating portion and the first connecting portion on the charging device 100 improves the charging convenience of the first electronic device 200, and the arrangement of the second accommodating portion and the second connecting portion on the charging device 100 improves the charging convenience of the second electronic device 300. This improved charging convenience for both the first and second electronic devices enhances the flexibility of the charging device 100 in use.

[0083] In some embodiments, when the first charging circuit 120 is connected to a power source at the power interface 110 and the first electronic device 200 is housed on the first receiving portion, the first electronic device 200 is charged by the power energy from the power source connected to the power interface 110 through the first connecting portion.

[0084] When the second charging circuit 130 is connected to a power source at the power interface 110 and the second electronic device 300 is housed on the second receiving portion, the power energy from the power source connected to the power interface 110 is used to charge the second electronic device 300 through the second connecting portion.

[0085] For example, when the first electronic device 200 is housed in the first receiving portion, the first charging circuit 120 can be connected to the first electronic device 200 through the first connecting portion provided on the first receiving portion. Based on this, when the power interface 110 is connected to a power source, the first charging circuit 120 can use the electrical energy from the power source connected to the power interface 110 to charge the first electronic device 200 through the first connecting portion, thereby improving the convenience of charging the first electronic device 200.

[0086] Accordingly, when the second electronic device 300 is housed in the second receiving portion, the second charging circuit 130 can connect to the second electronic device 300 through the second connecting portion provided on the second receiving portion. Based on this, when the power interface 110 is connected to a power source, the second charging circuit 130 can use the electrical energy from the power source connected to the power interface 110 to charge the second electronic device 300 through the second connecting portion, thereby improving the convenience of charging the second electronic device 300.

[0087] In some embodiments, when the power interface 110 is not connected to a power source and the first electronic device 200 is housed on the first receiving portion, the first charging circuit 120 uses the power energy of the battery 140 to charge the first electronic device 200 through the first connection portion.

[0088] When the power interface 110 is not connected to a power source and the first electronic device 200 is housed on the second receiving portion, the second charging circuit 130 uses the power energy of the battery 140 to charge the second electronic device 300 through the second connection portion.

[0089] For example, when the power interface 110 is not connected to a power source and the first electronic device 200 is housed on the first receiving portion, the power source cannot provide power to the first charging circuit 120. However, the battery 140 of the charging device 100 can provide power to the first charging circuit 120. In this case, the first charging circuit 120 can use the power of the battery 140 to charge the first electronic device 200 through the first connection portion, thereby improving the convenience of charging the first electronic device 200.

[0090] Correspondingly, when the power interface 110 is not connected to a power source and the second electronic device 300 is housed on the second receiving portion, the power source cannot provide power to the second charging circuit 130. However, the battery 140 of the charging device 100 can provide power to the second charging circuit 130. In this case, the second charging circuit 130 can use the power of the battery 140 to charge the second electronic device 300 through the second connection portion, thereby improving the convenience of charging the second electronic device 300.

[0091] In some embodiments, the charging device 100 further includes an overvoltage protection circuit 150; the overvoltage protection circuit 150 is connected to the power interface 110, the first charging circuit 120 and the second charging circuit 130 respectively; the overvoltage protection circuit 150 is used to provide overvoltage protection for the first charging circuit 120 and the second charging circuit 130.

[0092] For example, overvoltage protection circuit 150 can be used to indicate a circuit with overvoltage protection function.

[0093] like Figure 2As shown, taking power interface 110 as a Type-C interface, the first charging circuit 120 includes a first charging chip U1, and the second charging circuit 130 includes a second charging chip U2 as an example. The Type-C interface can be connected to an overvoltage protection circuit 150 through the VBUS pin. The overvoltage protection circuit 150 can be connected to the VIN1 pin of the first charging chip U1 and the VIN2 pin of the second charging chip U2 respectively. Then, when the Type-C interface is connected to a power source through a power adapter, the overvoltage protection circuit 150 can provide overvoltage protection for both the first charging chip U1 and the second charging chip U2.

[0094] Please combine Figure 2 See Figure 4D ,like Figure 4D As shown, the overvoltage protection circuit 150 may include an OVP chip U3. The OVP chip U3 can be connected to the VBUS pin of the Type-C interface via pins VIN7, VIN8, and VIN9. Correspondingly, the OVP chip U3 can be connected to the VIN1 pin of the first charging chip U1 and the VIN2 pin of the second charging chip U2 via pins VOUT5, VOUT6, and VOUT10, respectively. Therefore, the OVP chip U3 can provide overvoltage protection for both the first charging chip U1 and the second charging chip U2 when a power source is connected to the Type-C interface.

[0095] Based on the overvoltage protection circuit 150, the overvoltage protection circuit 150 can provide overvoltage protection for the first charging circuit 120 and the second charging circuit 130, which helps to improve the charging stability and charging safety of the charging device 100.

[0096] In some embodiments, the receiving portion of the charging device 100 includes a housing and a cover; one of the housing and the cover is provided with a Hall sensor 160, and the other of the housing and the cover is provided with a magnetic element, and the Hall sensor 160 is connected to the first charging circuit 120 and the second charging circuit 130 respectively; when the cover moves away from the housing, the magnetic field strength of the magnetic element changes, and the Hall sensor 160 outputs a preset electrical signal when the magnetic field strength of the magnetic element changes, so that the first charging circuit 120 responds to the preset electrical signal to control the first electronic device 200 connected to the first charging circuit 120 to enter the working state, and the second charging circuit 130 responds to the preset electrical signal to control the second electronic device 300 connected to the second charging circuit 130 to enter the working state.

[0097] For example, the receiving portion of the charging device 100 can be used to receive at least one of a first electronic device 200 and a second electronic device 300. In an exemplary embodiment, the receiving portion may include a first receiving portion and a second receiving portion. The first receiving portion is used to receive the first electronic device 200, and the second receiving portion is used to receive the second electronic device 300. However, this is not a limitation. For example, the first receiving portion may also include a first sub-receiving portion and a second sub-receiving portion, whereby the first sub-receiving portion can be used to receive one of a pair of first electronic devices 200, and the second sub-receiving portion can be used to receive the other of the pair of first electronic devices 200. Furthermore, the receiving portion may also include multiple first receiving portions and multiple second receiving portions to receive multiple first electronic devices 200 respectively through multiple first receiving portions, and multiple second electronic devices 300 respectively through multiple second receiving portions; this is not limited thereto.

[0098] The receiving portion may include a box body and a lid. For example, the interior of the box body may be partitioned. In an exemplary embodiment, the interior of the box body may be divided into a left region and a right region, with the left region serving as a first receiving portion and the right region serving as a second receiving portion. However, this is not a limitation and is not intended to be restrictive. Where the receiving portion includes both a first and a second receiving portion, the first and second receiving portions may share the same lid or may each have its own lid; this is not a limitation.

[0099] For example, the Hall sensor 160 is used to indicate a Hall effect-based magnetic sensing element capable of detecting the presence, intensity, or direction change of a magnetic field and converting it into an electrical signal. When the Hall sensor 160 is disposed in one of the housing or the lid, and a magnetic element is disposed in the other, and the Hall sensor 160 is connected to both the first charging circuit 120 and the second charging circuit 130, the Hall sensor 160 can detect the magnetic field strength of the magnetic element and output a preset electrical signal when the magnetic field strength changes. For example, when the lid is away from the housing, such as when the lid is opened, the magnetic element will correspondingly move away from the Hall sensor 160, and the Hall sensor 160 can output a preset electrical signal in response to the detected change in the magnetic field strength of the magnetic element. Accordingly, the Hall sensor 160 can transmit the preset electrical signal to the first charging circuit 120 and the second charging circuit 130 based on its connection with them. When the first charging circuit 120 receives a preset electrical signal, it can control the first electronic device 200 connected to the first charging circuit 120 to enter the working state, thereby waking up the first electronic device 200. Correspondingly, when the second charging circuit 130 receives a preset electrical signal, it can control the second electronic device 300 connected to the second charging circuit 130 to enter the working state, thereby waking up the second electronic device 300.

[0100] Taking a first charging circuit 120 including a first charging chip U1 and a second charging circuit 130 including a second charging chip U2 as an example, both the first charging chip U1 and the second charging chip U2 may be equipped with pins that have Hall switch signal detection functions, such as the EN1 pin of the first charging chip U1 and the EN2 pin of the second charging chip U2. Figure 2 As shown, the first charging chip U1 can be connected to the Hall sensor 160 through the EN1 pin, and the second charging chip U2 can be connected to the Hall sensor 160 through the EN2 pin. Then the Hall sensor 160 can be used to wake up the first charging chip U1 and the second charging chip U2.

[0101] Please combine Figure 2 See Figure 4E ,like Figure 4E As shown, the Hall sensor 160 may include a Hall device U4. The OUT pin of the Hall device U4 is connected to one end of a resistor R27. The other end of the resistor R27 is connected to the EN1 pin of the first charging chip U1 and one end of a resistor R28. The other end of the resistor R28 is connected to the EN2 pin of the second charging chip U2.

[0102] Based on the Hall sensor 160 and magnetic components on the charging device 100, the charging device 100 can use the Hall sensor 160 to control the first electronic device 200 and the second electronic device 300 housed in the receiving section to enter the working state, thereby realizing the wake-up function of the first electronic device 200 and the second electronic device 300. Therefore, the charging device 100 can be used both to charge the first electronic device 200 and the second electronic device 300, and also to wake them up, which improves the flexibility of use of the charging device 100.

[0103] In some implementations, the first charging circuit 120 is communicatively connected to the second charging circuit 130.

[0104] Taking a first charging circuit 120 including a first charging chip U1 and a second charging circuit 130 including a second charging chip U2 as an example, both the first charging chip U1 and the second charging chip U2 can be provided with general purpose input / output (GPIO) pins. Multiple GPIO pins can be provided on both the first charging chip U1 and the second charging chip U2. The GPIO pins of the first charging chip U1 can be connected to the GPIO pins of the second charging chip U2 to establish a communication connection between the first charging chip U1 and the second charging chip U2. Figure 2As shown, the GPIO pins of the first charging chip U1 may include the RX1 pin, TX1 pin, WAKE1_I pin, and WAKE1_O pin. The GPIO pins of the second charging chip U2 may include the TX2 pin, RX2 pin, WAKE2_I pin, and WAKE2_O pin. The first charging chip U1 can be connected to the RX2 pin of the second charging chip U2 via the TX1 pin, the TX2 pin of the second charging chip U2 via the RX1 pin, the WAKE2_O pin of the second charging chip U2 via the WAKE1_I pin, and the WAKE1_I pin of the second charging chip U2 via the WAKE1_O pin. Of course, the GPIO pins of the first charging chip U1 and the second charging chip U2 are not limited to these, and are not restricted here.

[0105] When the first charging circuit 120 and the second charging circuit 130 are in communication connection, the first charging circuit 120 and the second charging circuit 130 can perform corresponding communication interactions.

[0106] For example, when the first charging circuit 120 controls the first electronic device 200 connected to the first charging circuit 120 to enter the working state, it uses the communication connection between the first charging circuit 120 and the second charging circuit 130 to enable the second charging circuit 130 to control the second electronic device 300 connected to the second charging circuit 130 to enter the working state; when the second charging circuit 130 controls the second electronic device 300 connected to the second charging circuit 130 to enter the working state, it uses the communication connection between the second charging circuit 130 and the first charging circuit 120 to enable the first charging circuit 120 to control the first electronic device 200 connected to the first charging circuit 120 to enter the working state.

[0107] For example, the first charging circuit 120 and the second charging circuit 130 can have a mutual wake-up function. When the first charging circuit 120 controls the first electronic device 200 connected to it to enter the working state, the second charging circuit 130 may not have controlled the second electronic device 300 connected to it to enter the working state. In this case, the first charging circuit 120 can use the communication connection between the first charging circuit 120 and the second charging circuit 130 to wake up the second charging circuit 130, so that the second charging circuit 130 controls the second electronic device 300 connected to it to enter the working state. Correspondingly, when the second charging circuit 130 controls the second electronic device 300 connected to it to enter the working state, the first charging circuit 120 may not have controlled the first electronic device 200 connected to it to enter the working state. In this case, the second charging circuit 130 can use the communication connection between the second charging circuit 130 and the first charging circuit 120 to wake up the first charging circuit 120, so that the first charging circuit 120 controls the first electronic device 200 connected to it to enter the working state.

[0108] In one exemplary embodiment, the first electronic device 200 and the second electronic device 300 may be functionally related devices. Taking AR glasses as an example, and a smart ring as an example, the user can interact with the AR glasses via the smart ring. The AR glasses are housed, for example, in a first receiving portion of a charging device 100, and the smart ring is housed, for example, in a second receiving portion of the charging device 100, so that the first charging circuit 120 of the charging device 100 can be connected to the AR glasses, and the second charging circuit 130 of the charging device 100 can be connected to the smart ring. Accordingly, the charging device 100 can charge the AR glasses via the first charging circuit 120 and the smart ring via the second charging circuit 130. When the user opens the lid of the first receiving portion, the charging device 100 can control the AR glasses to enter a working state via the first charging circuit 120 to achieve "open-box wake-up" of the AR glasses. Accordingly, when the AR glasses are in a working state, the user also needs the smart ring to enter a working state, for example. The first charging device 100 can utilize the communication connection between the first charging circuit 120 and the second charging circuit 130 to enable the second charging circuit 130 to control the smart ring connected to the second charging circuit 130 to enter a working state. Therefore, when the user opens the lid of the second receiving part, the smart ring has already entered or is entering a working state, allowing the user to use the smart ring. However, this is not a limitation, nor are the first electronic device 200 and the second electronic device 300 limited to this specific configuration; no restrictions are imposed here.

[0109] When the first charging circuit 120 and the second charging circuit 130 are communicatively connected, the charging device 100 can utilize the communication connection between the first charging circuit 120 and the second charging circuit 130 to realize the mutual wake-up function between the first charging circuit 120 and the second charging circuit 130. This allows the second charging circuit 130 to control the second electronic device 300 to enter the working state when the first charging circuit 120 controls the first electronic device 200 to enter the working state, or vice versa. This improves the convenience of the charging device 100 in controlling the first electronic device 200 and the second electronic device 300.

[0110] For example, the charging device 100 also includes a first indicator light 171 and a second indicator light 172; the first indicator light 171 is connected to the first charging circuit 120, and the second indicator light 172 is connected to the second charging circuit 130; when the first charging circuit 120 and the second charging circuit 130 charge the battery 140 together, the first indicator light 171 and the second indicator light 172 use the communication connection between the first charging circuit 120 and the second charging circuit 130 to synchronously indicate the charging information of the first charging circuit 120 and the second charging circuit 130 on the battery 140.

[0111] For example, when the first charging circuit 120 charges the battery 140, the first charging circuit 120 can indicate the charging information of the battery 140 through the first indicator light 171. When the second charging circuit 130 charges the battery 140, the second charging circuit 130 can indicate the charging information of the battery 140 through the second indicator light 172. Accordingly, when the first charging circuit 120 and the second charging circuit 130 charge the battery 140 together, due to the hardware differences between the first charging circuit 120 and the second charging circuit 130, the first indicator light 171 and the second indicator light 172 may, for example, display the charging information of the battery 140 asynchronously. Based on this, the charging device 100 can utilize the communication connection between the first charging circuit 120 and the second charging circuit 130 to make the first indicator light 171 and the second indicator light 172 synchronously indicate the charging information of the battery 140 by the first charging circuit 120 and the second charging circuit 130.

[0112] Of course, the functions of the first indicator light 171 and the second indicator light 172 are not limited to this. For example, when the first charging circuit 120 controls the first electronic device 200 to enter the working state, the first indicator light 171 can also be used to indicate the power information of the first electronic device 200. When the second charging circuit 130 controls the second electronic device 300 to enter the working state, the second indicator light 172 can also be used to indicate the power information of the second electronic device 300. No further limitations are imposed here.

[0113] In one exemplary implementation, such as Figure 2 As shown, the first indicator light 171 and the second indicator light 172 may include light-emitting diodes (LEDs). For example, both the first indicator light 171 and the second indicator light 172 may include red LEDs, green LEDs, blue LEDs, etc., without limitation. Taking the first charging circuit 120 including a first charging chip U1 and the second charging circuit 130 including a second charging chip U2 as an example, the first indicator light 171 can be connected to the GPIO pin of the first charging chip U1, and the second indicator light 172 can be connected to the GPIO pin of the second charging chip U2.

[0114] When the first charging circuit 120 and the second charging circuit 130 are in communication connection, the charging device 100 can use the communication connection between the first charging circuit 120 and the second charging circuit 130 to achieve consistency in the indication of charging information of the battery 140 by the first indicator light 171 and the second indicator light 172, which is conducive to improving the convenience of the charging device 100 in controlling the first indicator light 171 and the second indicator light 172.

[0115] In some embodiments, the charging device 100 further includes a first temperature sensor and a second temperature sensor. The first temperature sensor is connected to a first charging circuit 120, and the second temperature sensor is connected to a second charging circuit 130. Both the first and second temperature sensors can be used to detect the temperature of the battery 140.

[0116] For example, the first temperature sensor and the second temperature sensor can be NTC (Negative Temperature Coefficient Sensor) temperature sensors, but they are not limited to this and are not restricted here.

[0117] like Figure 2As shown, taking the first charging circuit 120 including a first charging chip U1, the second charging circuit 130 including a second charging chip U2, the first temperature sensor including sensor NTC1, and the second temperature sensor including sensor NTC2 as an example, sensor NTC1 can be connected to the GPIO pin of the first charging chip U1. Correspondingly, sensor NTC2 can be connected to the GPIO pin of the second charging chip U2.

[0118] When the first charging circuit 120 and the second charging circuit are charging the battery 140 together, the temperature of the battery 140 can be detected by the first temperature sensor and the second temperature sensor to see if it is within a preset temperature range. Accordingly, if the temperature of the battery 140 is not within the preset temperature range, the charging device 100 can stop charging the battery 140 to improve the charging safety of the battery 140.

[0119] In some embodiments, the charging device 100 also includes a first button and a second button. The first button is connected to the first charging circuit 120, and the second button is connected to the second charging circuit 130. The first button and the second button can be used for functions such as hardware debouncing and waking up the charging device 100, and are not limited thereto.

[0120] like Figure 2 As shown, taking a first charging circuit 120 including a first charging chip U1, a second charging circuit 130 including a second charging chip U2, a first button being key1, and a second button being key2 as an example, the first charging chip U1 and the second charging chip U2 can be provided with pins for button detection, such as the KEY1 pin of the first charging chip U1 and the KEY2 pin of the second charging chip U2. The first charging chip U1 can be connected to key1 through the KEY1 pin, and the second charging chip U2 can be connected to key2 through the KEY2 pin.

[0121] The charging device 100 provided in this application embodiment includes a power interface 110, a first charging circuit 120, a second charging circuit 130, and a battery 140. The first charging circuit 120 is connected to the power interface 110 and the battery 140, and the second charging circuit 130 is also connected to the power interface 110 and the battery 140. When the power interface 110 is connected to a power source, the first charging circuit 120 and the second charging circuit 130 jointly charge the battery 140. The first charging circuit 120 is also used to connect to a first electronic device 200 to charge the first electronic device 200. The second charging circuit 130 is also used to connect to a second electronic device 300 to charge the second electronic device 300.

[0122] By using both the first charging circuit 120 and the second charging circuit 130 to charge the battery 140 of the charging device 100, dual charging of the battery 140 can be achieved, which helps to improve the charging efficiency of the battery 140. Since the first charging circuit 120 can be used to connect to the first electronic device 200 and the second charging circuit 130 can be used to connect to the second electronic device 300, the charging device 100 can charge at least one of the battery 140, the first electronic device 200, and the second electronic device 300, which helps to improve the flexibility of use of the charging device 100. Correspondingly, when the first charging circuit 120 is connected to the first electronic device 200 and the second charging circuit 130 is not connected to the second electronic device 300, the charging device 100 can charge the first electronic device 200 only through the first charging circuit 120. When the first charging circuit 120 is not connected to the first electronic device 200 and the second charging circuit 130 is connected to the second electronic device 300, the charging device 100 can charge the second electronic device 300 only through the second charging circuit 130, which helps to reduce the energy consumption of the charging device 100 when charging the first electronic device 200 or the second electronic device 300.
