Technical Field

[0001] This utility model belongs to the field of charger technology, specifically relating to a gallium nitride wall charger with foldable feet. Background Technology

[0002] Although gallium nitride (GaN) chargers are widely used in people's lives to quickly charge our digital devices, most of these GaN chargers are relatively large, with fixed and protruding metal prongs. When we carry them out, the metal parts of the prongs can easily bump into other objects, causing damage to the surface of our digital products and other expensive items. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gallium nitride wall charger with foldable feet, including a lower cover, an upper cover at the upper end of the lower cover, the upper cover and the lower cover being closed to form an accommodating cavity, an electronic module two being disposed inside the upper cover, an electronic module one being disposed on the side of the electronic module two, a PCB board being connected to the side of the electronic module one, a gallium nitride chip and a frequency modulation circuit for controlling the output and a constant current circuit for controlling the input being disposed on the PCB board, a pressure plate being disposed below the electronic module two, the pressure plate being connected and fixed to the lower cover by screws, a metal spring being installed at the bottom of the pressure plate, the pins being inserted into the corresponding positions of the lower cover, the pins being connected to the lower cover by rotation, and a PD output port being disposed at the top of the upper cover.

[0005] Preferably, the upper cover has an annular sealing groove inside its edge, and the lower cover has an annular sealing boss on its top surface, with the annular sealing boss of the lower cover engaging with the annular sealing groove of the upper cover.

[0006] Preferably, the top surface of the annular sealing boss is provided with a plurality of spaced sealing flanges, and the longitudinal section of the sealing flanges is triangular.

[0007] Preferably, an insulating sheet is provided below the electronic module one, the PCB board and the electronic module two, and a thermally conductive silicone sheet is provided below the insulating sheet.

[0008] Preferably, the various electrical components on electronic module one and electronic module two are connected and conductive through a PCB board.

[0009] Preferably, the upper and lower covers are made of PC molding.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention features high compatibility, meeting the charging needs of various devices; fast charging speed with high power output, significantly reducing charging time; low heat loss, resulting in higher charging efficiency; small size and light weight. Due to the use of gallium nitride material, the charger's size and weight are reduced, making it easy to carry and better foldable. The charger's size is further reduced after the prongs are folded, and the absence of exposed hard metal greatly reduces the risk of damaging other objects. Attached Figure Description
