[0023] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the drawings, some commonly used structures and components are depicted in simplified schematic form.

[0024] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0025] This embodiment provides a multifunctional charger that is small in size and lightweight. The wires are separated from the charger body, making it more convenient to carry. It has low power consumption and is not prone to overheating and damage like traditional chargers. It can also be adapted to adapters of different specifications, thereby realizing the multifunctional use of the charger.

[0026] Combine Figures 1 to 4 As shown, the multifunctional charger of this embodiment includes a charger housing 10 and a lower cover 20. The charger housing 10 is an ABS structural member or a metal aluminum structural member. The lower cover 20 installs the charger housing 10. The lower cover 20 is detachably connected to the charger housing 10. Using ABS structural members or metal aluminum structural members as the charger housing 10 can reduce costs and ensure consistency and accuracy in the production process.

[0027] In this embodiment, the lower cover 20 of this embodiment is mounted on the charger housing 10 by means of a locking member for easy disassembly, and its assembly is convenient and more efficient.

[0028] Combine Figure 1 and Figure 3 As shown, a circuit board 11 is installed in the charger housing 10 of this embodiment. One end of the charger housing 10 is an AC end and the other end is a DC end. The AC end of the charger housing 10 is provided with an adapter 12 to match adapters of different specifications. The DC end of the charger housing 10 is provided with a power cord 13 for charging. The charger housing 10 is filled with a colloid. In this embodiment, the colloid filled in the charger housing 10 is a mixture of thermal conductive silicone and sealant. The thermal conductive silicone and sealant are mixed and filled into the charger housing 10, which can effectively reduce heat loss, thereby better protecting the charger and charging equipment.

[0029] In this embodiment, the circuit board 11 is a gallium nitride structure. Made of gallium nitride, the circuit board 11 generates less heat and is less prone to overheating or damage than traditional silicon devices. Furthermore, the circuit board 11 consumes less power. Therefore, the gallium nitride charger is safer and more reliable.

[0030] Furthermore, the adapter 12 is a Type-C interface, so it can be applied to a variety of devices to be charged, and can also adapt to fast charging devices to improve charging efficiency. There are two power cords 13, which are installed at the DC end of the charger housing 10 for charging.

[0031] like Figure 4 As shown, the charging architecture of the circuit board 11 of this embodiment is a PFC+LLC architecture, which can realize two independent charging paths for the product, one path meets 5V-21V charging, and the other path meets 36V-55V charging.

[0032] In actual use, the multifunctional charger of this embodiment is small in size and lightweight. The wires are separated from the charger body, making it more convenient to carry. Its power consumption is low and it is not prone to overheating and damage like traditional chargers. It can adapt to adapters of different specifications, realizing the multifunctional use of the charger. Two power cords 13 are provided at the DC end of the charger housing 10, which can be charged separately or simultaneously, thereby improving charging efficiency.
