Description
All-in-one portable charger Priority information
[0001] The present application claims the priority of Chinese patent application CN2024222033675 with the title of All-in-one portable charger and the filing date of September 6, 2024, the content of which is incorporated herein by reference. TECHNICAL FIELD
[0002] The present application relates to the field of charging technology, in particular to an all-in-one portable charger that can support both wireless and wired charging. BACKGROUND
[0003] With the maturity of wireless charging technology and solutions, wireless charging is increasingly used as a power supply method for various electronic appliances. Many electronic products, such as smartwatches, only support wireless charging and no longer support wired charging. However, wired charging is still the main charging method preferred by many appliance users. Therefore, an all-in-one charger that integrates a wireless charger and a wired output has been developed.
[0004] The existing all-in-one portable chargers on the current market have the following product forms:
[0005] 1. Product 1 is composed of an input line, a middle card plate (a distribution plate), a wireless charging disc, and a wired output. The circuit is usually distributed in the middle card plate (distribution plate), wireless charging disc, etc. The middle card plate usually undertakes functions such as voltage distribution and distribution of lines, and sometimes integrates a wireless charging circuit on the middle card plate. Since the wired output has multiple interface forms, in order to be compatible with different interface specifications, this product form usually changes the output interface of the wired output end or uses a socket adapter to achieve compatibility with different output interface forms.
[0006] 2. Product 2 is composed of an input line, a wireless charging disc, and a wired output line. Compared with product 1, this product form integrates the wireless charging disc and the middle card plate in product 1, making the product more concise. By changing the output interface form of the output line or using a socket adapter, compatibility with different output interface forms is achieved.
[0007] 3. Product 3 is composed of a main body with two interfaces (male or female) on it, usually combined as A male + C female. A male is usually used as input, and C female can be used for input or output. When used as output, it is an all-in-one product form. When used as output, it can be combined with different cables to be compatible with different interface forms. For example, connecting a C-C cable can support C port output, and connecting a C-Lightning cable can support Lightning port output.
[0008] The products 1 and 2 are inconvenient to carry due to the long cables, and it is inconvenient for users to connect different cables to support different interfaces or external adapters when producing the products;
[0009] The product 3 supports no fast charging due to the USB-A input, and the product can only work at a power not higher than 5V-2A (10W). However, a product supporting PD3.0 can support an output power higher than 20V5A (100W), which obviously cannot meet the demand of users for increasing charging power. Moreover, the product has an A male input, which seems to have an input mode, but in fact, it is inconvenient to use due to the close distance between the wireless charging disc and the power supply.

The connection lines include signal lines for transmitting signals and / or power-carrying cables, etc.
[0056] The multi-in-one portable charger of the present application can avoid the influence of the heat generated by the power supply control circuit on the wireless charging circuit by arranging the power supply control circuit and the wireless charging coil in the first housing and the second housing, respectively, thereby improving the stability and reliability of the product. Meanwhile, the first housing and the second housing can be plugged together through the first external interface and the second external interface, so that the interconnection cable becomes a hanging rope, thereby improving the portability of the product.

In some possible embodiments, the first external interface 11 and the second external interface 21 can be interfaces conforming to any one of the following interface standards: USB, DC Out and Lightning.
[0059] Referring to FIGS. 3 and 4, in some embodiments, the first housing 100 includes a first interface mating surface 103, and the second housing 200 includes a second interface mating surface 203. The first interface mating surface 103 and the second interface mating surface 203 are attached to each other after the first external interface 11 and the second external interface 21 are plugged, thereby improving the portability of the product.

After the first body part 10 and the second body part 20 are plugged by the first external interface 11 and the second external interface 21, the protrusion of the first housing 100 is inserted into the groove of the second housing 200, thereby making the plugging of the first body part 10 and the second body part 20 more stable.
[0061] In some embodiments, the first housing 100 includes a third mating side surface 104, and the second housing 200 includes a second mating side surface 204. Both the first mating side surface 104 and the second mating side surface 204 are provided with a wire accommodating groove. Referring to FIG. 2, after the first body part 10 and the second body part 20 are plugged by the first external interface 11 and the second external interface 21, a part of the interconnection cable 30 is accommodated in the wire accommodating groove, and the part of the interconnection cable 30 outside the wire accommodating groove forms a hanging rope, thereby improving the portability of the product.
[0062] As shown in FIG. 6, 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 driving circuit 231. In this way, the power supply control circuit 131 with high heat emission is arranged in the first housing 100 of the first body part 10, thereby being separated from the wireless charging coil 25 and the wireless charging control and driving circuit 231 in the second housing 200 of the second body part 20, so as to avoid the heat emitted by the power supply control circuit 131 and the wireless charging control and driving circuit 231 from accumulating in the same housing and interfering with the wireless charging process.
[0063] As shown in FIG. 8, in some embodiments, the first circuit module 130 further comprises a wireless charging control and driving circuit 132. Also, in some embodiments, the first circuit module 130 further comprises a part of the wireless charging resonance circuit, such as the capacitance part in the resonance circuit, but the charging coil is still kept in the second body part 20, in which case the second circuit board can be omitted and the coil can be directly fixed in the second housing 200. In this way, the power supply control circuit 131 and the wireless charging control and driving circuit 132, which generate relatively high heat, are arranged in the first housing 100 of the first body part 10, and are thus separated from the wireless charging coil 25 in the second housing 200 of the second body part 20, so as to avoid the interference of the heat generated by the power supply control circuit 131 and the wireless charging control and driving circuit 132 with the wireless charging process.
[0064] As shown in FIG. 9, the connecting lines of the interconnection cable 30 include fast charging protocol communication connecting lines, USB-C connecting lines, and connecting wires of the wireless charging coil 25 driving circuit and the wireless charging coil 25.

In 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, so as to realize the function of fast charging, and 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 plug-in detection units, and identify whether the external devices are power adapters or devices to be charged, and control the working states 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 supply power to the portable charger, so that the portable charger can work normally no matter which one of the first or second external sockets the power adapter and the device to be charged are connected to, thereby realizing the function of bidirectional blind insertion while realizing fast charging and wireless charging.
[0066] With reference to FIG. 10, in some embodiments, the second circuit module 230 further comprises a wireless charging resonance circuit. Since the wireless charging resonance circuit generates less heat, the wireless charging resonance circuit can be disposed in the second housing 200 of the second body part 20 as part of the second circuit module 230 together with the wireless charging coil 25. With reference to FIG. 11, the connection lines of the interconnection cable 30 include USB-C standard communication and power lines, fast charging protocol communication connection lines, and connection wires of the wireless charging resonance circuit and the wireless charging drive circuit, where the first external interface 11 and the second external interface 21 are both USB-C standard interfaces.
