[0002] Battery trays, also known as power battery trays, battery boxes, and battery brackets, are components that carry and protect power batteries and are widely used in the field of new energy vehicles. First of all, high-quality battery trays should have good airtightness to prevent impurities, moisture, and gas mixing inside the battery, thereby ensuring the normal working state and life of the battery. Secondly, the airtightness design of the battery tray can effectively maintain the stability of the internal environment of the battery, prevent heat loss and temperature fluctuations, and thus improve the performance and life of the battery. And when the battery leaks or other abnormal conditions, the airtightness design can prevent harmful substances from leaking and avoid pollution and harm to the surrounding environment. In summary, airtightness is one of the most important detection indicators in battery pack trays, but the current existing battery trays are heavy and cannot guarantee the sealing performance of the box.

[0019] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0020] refer to Figure 1 , 2 As shown, the present invention provides a pelvic battery tray, including a frame 1 welded from high-strength steel. After welding, the frame 1 is subjected to electrophoresis treatment as a whole. The tensile strength grade of the selected steel is not less than 600MPa, which meets the strength, rigidity and collision and extrusion safety of the battery pack tray.

[0021] refer to Figure 3As shown, the frame 1 includes a side beam 11 and a longitudinal beam 12. The longitudinal beam 12 is vertically connected to two opposite side beams 11. The longitudinal beam 12 is vertically connected to two opposite side beams 11. The longitudinal beam 12 includes a top plate 121 and a bottom plate 122. The bottom plate 122 is surrounded by a peripheral edge 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, so that the pallet can stably support the heavy battery pack. The peripheral edges 123 are like a solid barrier, which increases the lateral stability and impact resistance of the pallet.

[0022] The pelvic-type battery tray adopts a double-layer cross-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 pelvic-type battery tray cleverly sets cavities 3 in its frame 1 and bottom plate 122, thereby effectively reducing the weight of the tray. At the same time, these cavities 3 also play a role in enhancing the structural strength.

[0023] The material of the frame 1 is processed by laser cutting, CNC bending and other processes to form the required shape and size. According to the design requirements, the various parts of the frame 1 are assembled together by welding, riveting or bolting. The strength and rigidity of the frame 1 should meet the requirements. The bottom plate 122 is connected to the frame 1 by welding. Good sealing should be ensured during the connection process to avoid gas leakage. Suitable sealing materials are selected to install sealing strips at the connection between the bottom plate 122 and the frame 1. During the installation process, the strips are ensured to fit tightly with the parts to ensure the sealing of the connection.

[0024] Compared with the prior art, the present invention 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 setting of the cavity can form a certain sealed space, providing a natural barrier for air tightness; a more compact and reasonable structural design is adopted, so that the pallet itself can be more easily sealed during the manufacturing process.
