[0020] In another embodiment of this utility model, a snap-fit ​​element is provided on the top inner surface of the upper shell 1, and the top of the inverter plate 5 is engaged with the snap-fit ​​element. After the inverter plate 5 slides into the track, when the upper shell 1 and the lower shell 2 are assembled, the snap-fit ​​element will engage with the top of the inverter plate 5, fixing the inverter plate 5 like a clamp to ensure its stability.

[0021] In another embodiment of the present invention, a cooling fan 10 is provided inside the housing, the cooling fan 10 is connected to the side panel 8, and the inner surface of the side panel 8 is provided with heat dissipation holes 9.

[0022] In another embodiment of this utility model, the front panel 11 is provided with a USB interface 13, which is connected to the USB port of the input / output board 7.

[0025] In another embodiment of this utility model, a decorative panel 16 is provided on the top of the outer casing. Users can design logos or patterns on the decorative panel 16.

[0026] In another embodiment of this utility model, the outer casing is provided with a handle 18. This allows for convenient handling of the power supply. The handle 18 is foldable, which effectively reduces the width of the power supply when folded.

[0027] In another embodiment of this utility model, the outer casing is provided with ventilation holes 17.

[0028] This utility model provides a compact energy storage power supply. By utilizing the internal space of the casing, the layout of each circuit board is made more reasonable, effectively reducing the size of the power supply and making it easier to carry. At the same time, the use of rails to install and fix the circuit boards makes the circuit boards more stable and improves the performance.

[0029] Structurally, the outer casing adopts a cuboid structure to maximize space utilization. The upper shell 1 and lower shell 2 are fastened together with screws. The circuit boards are arranged in a compact stacking manner to maximize space utilization while maintaining reasonable creepage distances between them. To simplify the internal structural design and avoid adding new structural components, the inverter board 5 does not use a separate bracket or traditional screw fixing method. Instead, a track is designed within the cavity of the lower shell 2. The inverter board 5 slides vertically into the track from one side and is secured after engaging with the snap-fit ​​mechanism of the upper shell 1. This significantly reduces structural design complexity and decreases the amount of plastic used, screws, and labor costs. In the power supply, both the inverter board 5 and the input / output board 7 are vertically arranged, a design that reduces space utilization within the power supply.

[0030] The inverter board 5 is adjacent to the battery pack 4. By setting the partition, after the upper shell 1 and the lower shell 2 are fastened in place, an isolation cavity belonging to the battery pack 4 is formed. To ensure heat dissipation of high-temperature components on the inverter board 5, a small but high-speed cooling fan 10 is used on one side, in conjunction with the heat dissipation holes 9 set on the side panel 8 for heat dissipation. At the same time, ventilation holes 17 are added to the outer shell to form a heat dissipation airflow for the inverter board 5, avoiding excessive heat accumulation inside the power supply and affecting the operation of the power supply.

[0031] The AC socket 3 is placed in the placement hole 12 and connected to the input / output board 7. At the same time, the input / output board 7 is connected to the inverter board 5 through pins, and then connected to the inverter 6. A gap is left between the input / output board 7 and the inverter board 5 to maintain a reasonable creepage distance.

[0032] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
