Description

Technical Field

[0001] The present application relates to the field of charging technology, and in particular to an all-in-one portable charger that can support both wireless and wired charging. Background Art

[0002] As wireless charging technology and solutions mature, it's becoming increasingly common for powering various electronic devices. Many electronic products, such as smartwatches, now exclusively support wireless charging and no longer support wired charging. However, wired charging remains the primary charging method and is preferred by many appliance users. This has led to the development of all-in-one chargers that combine both wireless charging and wired output.

[0003] Currently, there are two-in-one portable chargers with wireless and wired output on the market, mainly in the following product forms:

[0004] 1. Product 1 consists of an input cable, a mid-card board (breakout board), a wireless charging tray, and a wired output. The circuitry is typically located on the mid-card board (breakout board), the wireless charging tray, and other locations. The mid-card board typically handles voltage and line division, power distribution, and other functions. Wireless charging circuitry is sometimes integrated on the mid-card board. Since wired outputs have a variety of interface types, this product form often achieves compatibility with different interface specifications by replacing the output interface of the wired output or inserting an adapter.

[0005] 2. Product 2 consists of an input cable, a wireless charging pad, and a wired output cable. Compared to Product 1, this product combines the wireless charging pad and mid-card board in Product 1, making the product more compact. Compatibility with different output interface types can be achieved by changing the output cable's output interface or inserting an adapter.

[0006] 3. Product 3 consists of a main body with two connectors (male or female), typically a combination of A male + C female. The A male connector is typically used for input, while the C female connector can be used for both input and output. When used for output, it forms a two-in-one product. For output, it can be used with different cables, compatible with different connector types. For example, connecting a CC cable enables C-port output, while connecting a C-to-Lightning cable enables Lightning output.

[0007] Products 1 and 2 both have long cables, which are relatively inconvenient to carry. Furthermore, when manufacturing the products, different cables must be connected to support different interfaces, or external adapters must be used, which adds inconvenience to users.

[0008] Because Product 3 uses USB-A input, its output does not support fast charging. It can only operate at a power level no higher than 5V-2A (10W). While current wired charging products that support PD3.0 can already support output power levels exceeding 20V5A (100W), this clearly cannot meet the ever-increasing demand for charging power. Furthermore, while the product's built-in A-type male input may appear to be a built-in input method, in reality, the wireless charging pad is too close to a power source, making it inconvenient to use. Summary of the Invention

[0009] The purpose of this application is to provide a new all-in-one charger with stronger compatibility and more flexible and convenient use.

[0010] To this end, the present application proposes an all-in-one portable charger, which includes:

[0049] The specific implementation of this application is further described below with reference to the accompanying drawings.

[0050] Please see Figures 1 to 5 An all-in-one portable charger 1 according to one embodiment of the present application includes: a first split part 10 , a second split part 20 and an interconnection cable 30 .

[0051] The first split portion 10 includes a first shell 100, a first external socket 11, and a first circuit board 130. The first circuit board 130 is housed within the first shell 100. The first external socket 11 is connected to the first circuit board 130. The first circuit board 130 is provided with a first circuit module 130, and the first circuit module 130 includes at least a power supply control circuit 131. The first shell 100 includes a first upper shell 100a and a first lower shell 100b. The first circuit board 130 is housed within a cavity formed by the first upper shell 100a and the first lower shell 100b. A first wire outlet 108 is also provided on the first docking side surface 102 of the first shell 100. The interconnection cable 30 passes through the first wire outlet 108 and is connected to the first circuit board 130. In addition, a charging indicator light 106 is provided on the first upper shell 100a of the first shell 100.

[0052] The second split portion 20 includes a second housing 200, a second external socket 21, and a second circuit board 23. The second circuit board 23 is housed within the second housing 200. The second external socket 21 is connected to the second circuit board 23. The second circuit board 23 is provided with a second circuit module 230. The second circuit module 230 includes at least a wireless charging coil 25. The first circuit module 130 and the second circuit module 230 together form a circuit for wireless charging and wired charging. The second housing 200 includes a second upper housing 200a and a second lower housing 200b. The second circuit board 23 is housed within a cavity formed by the second upper housing 200a and the second lower housing 200b. The second housing 200 includes a third docking side surface 202, which is provided with a second cable outlet 208. The interconnect cable 30 passes through the second cable outlet 208 and connects to the second circuit board.

[0053] The interconnection cable 30 is connected to the first circuit board 130 and the second circuit board 23 at both ends. The interconnection cable 30 includes multiple connecting wires for connecting the first circuit module 130 to the second circuit module 230. It is worth noting that the type and number of connecting wires depend on the hardware standards of the first and second external interfaces and the specific topology of the first circuit module 130 and the second circuit module 230, as will be explained in detail below. These connecting wires include signal wires for transmitting signals and / or power-carrying cables.

[0054] The all-in-one portable charger of this application houses the power supply control circuit and wireless charging coil in separate first and second housings, preventing heating from the power supply control circuit and affecting the operation of the wireless charging circuit, thereby improving the stability and reliability of the product. Furthermore, the first and second housings can be connected together via a first external socket and a second external socket, allowing the interconnecting cable to function as a lanyard, thus enhancing the product's portability.

[0055] Also refer to Figure 5 The second split portion 20 includes a wireless charging coil 25, allowing users to perform both wired and wireless charging. The second lower housing 200b is equipped with a coil socket 207 for securing the wireless charging coil 25. A wireless charging area 205 is also provided in the corresponding position of the second upper housing 200a to facilitate wireless charging.

[0056] In some embodiments, the first external socket 11 and the second external socket 21 are respectively a male port and a female port that match each other. In some possible embodiments, the first external socket 11 and the second external socket 21 can be interfaces that comply with any of the following interface standards: USB, DC Out, and Lightning.

[0057] Also refer to Figure 3 and Figure 4In some embodiments, the first shell 100 includes a first interface docking surface 103, and the second shell 200 includes a second interface docking surface 203. The first interface docking surface 103 and the second interface docking surface 203 fit together after the first external socket 11 and the second external socket 21 are plugged in, thereby improving the portability of the product.

[0058] Also refer to Figure 3 and Figure 4 In some embodiments, the first interface surface 103 of the first housing 100 is provided with a boss, and the second interface surface 203 of the second housing 200 is provided with a corresponding groove that fits the boss. When the first and second sub-units 10 and 20 are plugged into each other through the first and second external sockets 11 and 21, the boss of the first housing 100 fits into the groove of the second housing 200, thereby ensuring a more stable connection between the first and second sub-units 10 and 20.

[0059] In some embodiments, the first housing 100 includes a third docking side surface 104, the second housing 200 includes a second docking side surface 204, and both the first docking side surface 104 and the second docking side surface 204 are provided with a wire accommodating groove. Figure 2 When the first split part 10 and the second split part 20 are plugged into the first external socket 11 and the second external socket 21, a portion of the interconnection cable 30 is stored in the cable trough, and the portion of the interconnection cable 30 outside the cable trough forms a hanging rope, thereby improving the portability of the product.

[0060] like Figure 6 As shown, in some embodiments, the first circuit module 130 includes a power supply control circuit, and the second circuit module 230 includes a wireless charging control and drive circuit 231. The power supply control circuit 131, which generates relatively high heat, is disposed within the first housing 100 of the first split portion 10, thereby being separated from the wireless charging coil 25 and the wireless charging control and drive circuit 231 within the second housing 200 of the second split portion 20. This prevents heat generated by the power supply control circuit 131 and the wireless charging control and drive circuit 231 from accumulating within the same housing and interfering with the wireless charging process.

[0061] like Figure 8As shown, in some embodiments, the first circuit module 130 also includes a wireless charging control and drive circuit 132. In addition, in some embodiments, the first circuit module 130 also includes a portion of the wireless charging resonant circuit, such as the capacitor portion of the resonant circuit, but the charging coil is still retained within the second split portion 20. In this case, the second circuit board can be omitted from the second split portion 20, and the coil can be directly fixed within the second housing 200. In this way, the power supply control circuit 131 and the wireless charging control and drive circuit 132, which generate relatively high heat, are both disposed within the first housing 100 of the first split portion 10, thereby being separated from the wireless charging coil 25 within the second housing 200 of the second split portion 20, thereby preventing the heat generated by the power supply control circuit 131 and the wireless charging control and drive circuit 132 from interfering with the wireless charging process.

[0062] like Figure 9 As shown, the connection wires of the interconnection cable 30 include a fast charging protocol communication connection wire, a USB-C connection wire, and a connection wire between the wireless charging coil 25 drive circuit and the wireless charging coil 25.

[0063] like Figure 10 As shown, in some embodiments, the power supply control circuit 131 includes a first insertion detection unit, a second insertion detection unit, a first switch unit, a second switch unit, a voltage control unit and a fast charging protocol control unit; wherein, the first external socket 11 is electrically connected to the voltage control unit via the controlled end of the first switch unit, the second external socket 21 is electrically connected to the voltage control unit via the controlled end of the second switch unit, the control end of the first switch unit is electrically connected to the fast charging protocol control unit, the control end of the second switch unit is electrically connected to the fast charging protocol control unit, the fast charging protocol control unit is electrically connected to the first external socket 11 via the first insertion detection unit, and the fast charging protocol control unit is also electrically connected to the second external socket 21 via the second insertion detection unit, and the voltage control unit is electrically connected to the fast charging protocol control unit and the wireless charging unit. During the charging process, the fast charging protocol control unit can negotiate the fast charging protocol with the power adapter and the device to be charged, thereby realizing the fast charging function. At the same time, the fast charging protocol control unit can intelligently identify whether the first and second external sockets are connected to external devices through the first and second insertion detection units, and identify whether the external device is a power adapter or a device to be charged, and control the working status of the first and second switch units according to the identification results, so that the power adapter can be connected to the voltage control unit to power the portable charger, so that no matter which of the first or second external sockets the power adapter and the device to be charged are connected to, the portable charger can work normally, thereby realizing the function of two-way blind plugging while realizing fast charging and wireless charging.

[0064] Continue to refer Figure 10In other embodiments, the second circuit module 230 further includes a wireless charging resonant circuit. Since the wireless charging resonant circuit generates less heat, the wireless charging resonant circuit can be provided as part of the second circuit module 230 together with the wireless charging coil 25 in the second housing 200 of the second split portion 20. Figure 11 The first external socket 11 and the second external socket 21 are both USB-C standard interfaces, and the connecting wires of the interconnection cable 30 include USB-C standard communication and power cables, fast charging protocol communication cables, and connecting wires between the wireless charging resonant circuit and the wireless charging drive circuit.

[0065] In other embodiments, the second circuit module 230 may further include a wireless charging control and driving circuit, which together with the wireless charging resonant circuit in the second housing 200 constitutes a complete wireless charging function.

[0066] like Figure 12 As shown, the all-in-one portable charger 1 can be connected to the adapter 2 through the first external socket 11 and supply power to the external device to be charged through the external charging cable 3.

[0067] like Figure 13 As shown, the all-in-one portable charger 1 can be connected to the adapter 2 via the external charging cable 3 through the second external socket 21 and supply power to the external device to be charged through the first external socket 11.

[0068] In other embodiments, the number of first external sockets 11 and second external sockets 21 can be configured as needed. In addition to the aforementioned embodiment in which the first split portion 10 includes one first external socket 11 and the second split portion 20 includes one second external socket 21, and the first external socket 11 and the second external socket 21 are matched male and female sockets, the sockets can also be arranged in the following manner:

[0069] (1) The first split portion 10 has a first external socket 11, which can be a male or female socket. The second split portion 20 has no interface and only provides wireless charging;

[0070] (2) The first split portion 10 has two or more first external sockets 11, which can be male or female, and are external sockets directly connected to the first circuit board. The second split portion 20 has no interface and only provides wireless charging;

[0071] (3) The first split portion 10 has one or more first external sockets 11, which can be male or female; the second split portion 20 has one or more second external sockets 21, which can be male or female. The type of the second external socket 21 can be an external socket directly connected to the second circuit board, or an external socket led out through a cable, or a combination of the two types.

[0072] In summary, the all-in-one portable charger provided in this application is portable and easy to use, especially supporting both wireless charging and wired charging while supporting bidirectional blind plugging and fast charging, and can support external charging devices and adapters with various interface types when used with an external charging cable.

[0073] The above description of the present application and its embodiments is non-limiting. The drawings show only one embodiment of the present application, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of this application, designs a structure and embodiment similar to this technical solution without creatively designing, they shall fall within the scope of protection of this application.
