AI Technical Summary
Technical Problem
In the existing technology, the sealing effect of the battery pack casing is not good, and the sealing ring is prone to displacement and abnormal deformation, which affects the service life of the battery pack.
Method used
A boss structure is provided on the connection surface between the lid and the body, and a seal is provided on the side of the boss structure facing the inside of the body. The boss structure reliably compresses the seal between the lid and the body, preventing the seal from shifting or deforming abnormally.
Benefits of technology
This improves the sealing effectiveness of the battery pack housing, ensuring that the seals are not easily displaced or deformed, and enhances the overall sealing performance of the battery pack.
