[0020] Embodiment:

[0021] As shown in the attached Figure 1 、 2 figures, this example provides a thin and multi-output device, including a base 1, a heat-conducting boss 101, an input socket hole 102, a support column 103, a nameplate pasting position 104, an output wire opening 105, a main control board positioning boss 106, an output wire one 201, an output wire two 202, an output wire three 203, an output wire four 204, an output wire five 205, an output wire six 206, an upper cover 3, a sealing groove 301, a lamp board positioning column 302, a lamp board opening 303, a lamp control board 4, a sealing ring 5, a main control board 6, an input socket 7, and a control panel 8. Its characteristics are: the base 1 and the upper cover 3 are fixedly connected by 4 screws. The base 1 includes a heat-conducting boss 101, an input socket hole 102, a support column 103, a nameplate pasting position 104, an output wire opening 105, and a main board positioning boss 106. The upper cover 3 includes an upper cover fixing hole 301, a lamp board positioning column 302, and a lamp board opening 303. A sealing groove 301 is reserved between the base 1 and the upper cover 3, and the sealing ring 5 is placed in the sealing groove 301. The main control board 6 is reserved with 4 round holes for fixing the main control board 6 on the main control board positioning boss 106 by screws. The lamp control board 4 is fixedly connected to the upper cover 3 by screws, and the control panel 8 is pasted on the upper cover 3. The upper cover 3 is provided with round holes for fixing the lamp post and displaying the usage status of the charger.

[0022] In this example, the base 1 and the upper cover 3 are fixedly connected by 4 screws. The base 1 includes a heat-conducting boss 101, an input socket hole 102, support columns 103 that can effectively prevent the main control board 6 from bending and deforming, a nameplate pasting position 104 for pasting the product nameplate, an output wire opening 105, and a motherboard positioning boss 106 with a limiting platform, which can effectively prevent reverse insertion and socket rotation. The upper cover 3 includes upper cover fixing holes 301, lamp board positioning columns 302, and lamp board openings 303. A sealing groove 301 is reserved between the base 1 and the upper cover 3; the lamp control board 4 is fixed on the upper cover 3 with six screws. The sealing ring 5 is installed in the sealing groove 301, and the sealing ring deforms through the buckling of the upper and lower covers, thereby playing a waterproof role.

[0023] In this example, there are three input sockets 7 in total, including an AC input wire, a DC input wire, and a vehicle-mounted input wire; the output wires include a first output wire 201, a second output wire 202, a third output wire 203, a fourth output wire 204, a fifth output wire 205, and a sixth output wire 206.

[0024] In this example, the main control board 6 uses horizontal resistors and capacitors, an ultra-thin transformer, and a highly integrated chip, which reduces the overall height for easy carrying. The heat-generating components are placed at the edge of the main control board 6 and are connected to the heat-conducting boss 101 through heat-conducting silicone grease to transfer the heat to the base 1. The heat is dissipated into the air through the base 1 and the upper cover 3 to achieve the purpose of heat dissipation. The overall length of the bottom of the main control board is relatively long, and the middle position is prone to deformation. Support columns 103 are reserved on the base 1. The support columns 103 are selected at positions on the back of the main control board 6 without components to support the main control board 6; there are input socket holes 102 and output wire openings 105 on the side of the base 1. There are sealing rings between the input socket 7 and the output wire 2 and the base 1, which play a waterproof role. Grooves are designed on the surfaces of the base 1 and the upper cover 3, increasing the surface area and thus increasing the heat dissipation area.

[0025] In this example, the first output wire 201 is the first DC interface, the second output wire 202 is the first USB interface, the third output wire 203 is the first Type-C interface, the fourth output wire 204 is the second DC interface, the fifth output wire 205 is the second Type-C output wire, and the sixth output wire 206 is the second USB interface.

[0026] This ultra-thin multi-output charging device has three input wires and six output wires. There are sealing rings for both the input socket and the output wires, and there is a sealing ring 5 between the base 1 and the upper cover 3, with excellent overall waterproof performance, suitable for outdoor use. The charging device has two charging modes: fast charging and standard charging. When using the output wire, a light will turn on at the corresponding position.

[0027] The present utility model proposes an ultra-thin multi-channel charging device, which uses horizontal electrolytic capacitors, ultra-thin transformers, and highly integrated chips to achieve a thinner design. Through a reasonable heat dissipation and heat conduction structure, the heat generated in a narrow space during operation can be quickly and efficiently dissipated, ensuring the stable operation of the device. It has the remarkable advantages of reasonable structure, small volume, excellent waterproof and dustproof performance, and easy to carry.
