[0001] This invention relates to the field of energy storage box technology, and in particular to the structure of an energy storage box. Background Technology
[0002] Energy storage boxes are widely used to charge digital devices such as laptops, tablets, and mobile phones. However, existing energy storage boxes have the following drawbacks:
[0003] (1) There is only one large fan, which blows both the battery pack and the PCB board, resulting in poor heat dissipation, lack of specificity, and loud noise.
[0004] (2) Exposed fastening screws on the front and rear shells affect the appearance;
[0005] (3) The handle has many components and the assembly is complicated, which affects the assembly efficiency.
[0006] To overcome the above shortcomings, we invented a structure for an energy storage box. Summary of the Invention

This solution has the following advantages:
[0021] (1) The enclosure frame assembly is a key supporting component of the energy storage box and is made entirely of metal. This ensures the high structural strength of the energy storage box. The fixing screws of the left metal plate, right metal plate, and top metal plate are all located inside the energy storage box and are not exposed.
[0022] (2) The front shell and the rear shell are inserted into the bottom shell. The bottom shell is provided with a limiting bone to prevent internal compression deformation. The left and right sides of the front shell and the rear shell are respectively provided with inwardly curved screw ears. The screw ears are fixed to the left front support column, the left rear support column, the right front support column, and the right rear support column by screws.

[0024] (4) The inner cover of the handle is the inner lining of the outer cover of the handle. The outer cover of the handle is fixed to the top metal plate and the top screw posts of the front and rear shells by screws. Then the outer cover of the handle and the inner cover of the handle are fastened together, ensuring that the screws are not visible on the outside of the outer cover of the handle. The handle is designed directly on the handle cover assembly, which simplifies the assembly work and improves the assembly efficiency.
[0025] (5) The heat dissipation mechanism forms heat dissipation channels with the air inlet on the right cover and the air outlet on the left cover respectively. The battery pack is designed with multiple heat dissipation holes and the battery cover is equipped with heat dissipation windows to ensure that the heat of the energy storage box is dissipated quickly. The inverter support plate can block the hot air blown by the fan of the heat dissipation mechanism (referring to the hot air generated by the inverter board assembly) from flowing back into the battery pack.
