The sealing performance of the battery pack will directly affect the normal operation of the battery pack system and the safety of the entire vehicle. In order to improve the sealing performance of the battery pack, the sealing structure of the battery pack must be reasonably designed based on the characteristics of the sealing material to meet high standards. At present, sealing foam is mainly used as a seal between the upper cover and the base of the power battery. The rivet nuts between the upper cover and the base are assembled and tightened while causing a certain amount of compression of the foam to meet the sealing requirements. Commonly used sealing foam has a certain thickness and width to match the frame, and bolt holes are reserved in the middle to ensure the sealing effect through compression over a larger area, which is more costly. In addition, the assembly process requires accurate hole alignment of the foam, upper cover, and box body, which requires high machining requirements.
