The shielding assembly 3 includes a top cover 33 for shielding electromagnetic fields, which is disposed on the wall 22, and the shielding assembly 3 is located on the wall 22 away from the support member 11. On the side, a second sealing element 5 is also provided between the top cover 33 and the enclosure wall 22. The enclosure wall 22, the top cover 33 and the second sealing element 5 are fastened together by bolts. A partition 32 is provided at the end of the top cover 33 away from the enclosure wall 22, and the partition 32 is located inside the top cover 33. The support assembly 1 includes a fixing component, which includes a number of longitudinal reinforcing ribs 12 spaced apart on the side of the support member 11 away from the enclosure wall 22. A number of first transverse reinforcing ribs 13 and a number of second transverse reinforcing ribs 14 are provided between the number of longitudinal reinforcing ribs 12 and the support member 11. The number of longitudinal reinforcing ribs 12, a pair of first transverse reinforcing ribs 13, a number of second transverse reinforcing ribs 14 and the support member 11 are fastened together by bolts.

[0037] Firstly, the support component 1 enhances the structural strength of the enclosure through longitudinal and transverse reinforcing ribs, ensuring the stability of the battery box under temperature changes. Secondly, the protective component 2 effectively protects the internal electrical components from the influence of the external environment through the enclosure 22 and the first seal 4, improving the protective performance of the battery box. Finally, the shielding component 3 provides electromagnetic shielding through the top cover 33 and the second seal 5, reducing the impact of electromagnetic interference on the electrical components. The bolt fastening method ensures a tight connection between the components, further enhancing the overall structural stability and sealing, and improving the battery box's resistance to temperature differences and durability.

[0038] Each longitudinal reinforcing rib 12, each first transverse reinforcing rib 13 and each second transverse reinforcing rib 14 is U-shaped, two first transverse reinforcing ribs 13 are respectively transversely clamped at two ends of a plurality of longitudinal reinforcing ribs 12, a plurality of second transverse reinforcing ribs 14 are arranged between the two first transverse reinforcing ribs 13, and each second transverse reinforcing rib 14 is transversely clamped on the longitudinal reinforcing rib 12, and the plurality of first transverse reinforcing ribs 13 and the plurality of second transverse reinforcing ribs 14 are arranged on the side of the support piece 11 away from the surrounding wall 22.

[0039] The arrangement and U-shaped design of the longitudinal reinforcing rib 12, the first transverse reinforcing rib 13 and each second transverse reinforcing rib 14 greatly improve the structural strength and deformation resistance of the battery box, especially in an environment with large temperature difference, can effectively disperse stress and prevent the deformation of the box body, and the clamping design of the transverse reinforcing rib and the longitudinal reinforcing rib 12 further improves the stability and connection strength of the overall structure, ensuring the reliability of the support assembly 1 under complex working conditions; in addition, the arrangement of the reinforcing rib optimizes the stress distribution of the box body, reduces the load of the support piece 11, prolongs the service life of the battery box, and improves the temperature difference resistance, mechanical strength and durability of the battery box.

[0040] The U-shaped opening of each longitudinal transverse reinforcing rib and each first transverse reinforcing rib 13 faces, and the U-shaped opening of each second transverse reinforcing rib 14 faces the longitudinal reinforcing rib 12.

[0042] The edges of the four sides of the support piece 11 extend towards the side away from the first sealing piece 4 to form a protective wall for protecting the fixed components.

[0043] The protective wall is formed at the four edges of the support 11 and extends towards the side away from the first sealing member 4, which can protect the fixed components from external impact, dust or moisture, improve the protection performance of the battery box, and enhance the overall structural strength of the support 11 through the extension design of the protective wall, further improve the anti-deformation ability and stability of the battery box, especially in the environment with large temperature difference, which can better resist the influence of thermal expansion and cold contraction, and the protective wall also provides additional support and fixing effect for the fixed components, ensures the connection between the reinforcing ribs and the support 11 is more stable, thereby prolonging the service life of the battery box and improving its reliability.

[0044] The two ends of the surrounding wall 22 are provided with the fixing members 21, and the two fixing members 21 are respectively arranged on the first sealing member 4 and the second sealing member 5.

[0048] A plurality of cavities 221 for heat insulation are spaced on the side of the surrounding wall 22 close to the guide member, and if an opening for communication with the outside needs to be formed on the surrounding wall 22, the opening needs to avoid directly penetrating the cavity 221, the cavity 221 structure can effectively reduce the weight of the surrounding wall 22 while maintaining sufficient strength and rigidity, thereby improving the overall lightweight level of the battery box, and secondly, the cavity 221 can be used as a heat insulation layer to reduce the influence of external temperature difference on the electrical components in the battery box and enhance the temperature difference resistance of the battery box.

[0049] The side of the partition plate 32 close to the surrounding wall 22 abuts against the limiting member 31 for limiting the battery block, and the limiting member 31 and the partition plate 32 are connected through bolts.

[0050] The limiting member 31 can effectively fix the position of the battery block and prevent displacement of the battery block due to vibration or movement in the battery box, thereby ensuring the stability and safety of the battery block, in addition, the bolt connection mode facilitates the installation and disassembly of the partition plate 32 and the limiting member 31, improves the maintainability and operability of the battery box, and also provides convenience for replacement or adjustment of the battery block.
