AI Technical Summary
In existing technologies, the need to install welding nuts for fastening the battery casing inside the lower beam results in poor production efficiency.
The design employs a pair of lower side beams on the left and right sides and a battery casing. By using an overlapping fixing method where an inner flange extends from the inside of the lower side beam and an outer flange extends from the outside of the battery casing, the reliance on welded nuts is eliminated, thus achieving a tight fastening.
It improves the production efficiency of the battery mounting structure, enhances side impact performance and cooling performance, and increases battery capacity.
