[0019] The utility model will be explained in detail below in combination with the drawings and specific embodiment. The embodiment is implemented with the utility model technical scheme as the premise, gives detailed implementation mode and specific operation process, but the protection scope of the utility model is not limited to the following examples.

[0020] As shown in the reference Figure 1 , 2 The utility model provides a kind of pot cavity formula battery tray, including frame body 1 by high-strength steel material welding, after welding is completed, frame body 1 overall carries out electrophoresis treatment, the tensile strength grade of selected steel material is not less than 600MPa, satisfies battery pack tray strength, rigidity and collision extrusion safety;

[0021] As shown in the reference Figure 3As shown, the frame 1 includes side beams 11 and longitudinal beams 12. The longitudinal beams 12 are vertically connected to the two opposite side beams 11. The longitudinal beams 12 include a top plate 121 and a bottom plate 122. The bottom plate 122 is surrounded by a perimeter 123. The flat bottom design not only facilitates the stable placement of the pallet during transportation and installation, but also improves its load-bearing capacity, enabling the pallet to stably support the heavy battery pack. The perimeter 123 acts as a solid barrier, increasing the lateral stability and impact resistance of the pallet.

[0022] The basin-type battery tray uses a double-section design. This innovative design not only takes into account the requirements of lightweight and high strength, but also cleverly improves the airtightness of the tray. Specifically, the basin-type battery tray achieves effective weight reduction by cleverly setting cavities 3 in its frame 1 and base plate 122. At the same time, these cavities 3 also play a role in enhancing the structural strength.

[0023] The material of frame 1 is processed using laser cutting, CNC bending, and other processes to form the required shape and size. According to design requirements, the various parts of frame 1 are assembled together using welding, riveting, or bolting. It must be ensured that the strength and rigidity of frame 1 meet the requirements. The base plate 122 is connected to frame 1 using welding. During the connection process, good sealing must be ensured to prevent gas leakage. Suitable sealing materials are selected, and sealing strips are installed at the connection between the base plate 122 and frame 1. During installation, it is ensured that the sealing strips fit tightly against the parts to ensure a tight seal at the connection.

[0024] Compared with the prior art, this utility model adopts a double-layer cross-section design and provides cavities in the frame 1 and the bottom plate 122. This design not only reduces the weight of the pallet but also increases the structural strength of the pallet. The cavity can form a certain sealing space, providing a natural barrier for airtightness. The more compact and reasonable structural design makes it easier to achieve sealing during the manufacturing process of the pallet.
