AI Technical Summary
Technical Problem
In the existing technology, the assembly of the expansion beam requires space inside the battery box, and welding poses a risk of damaging the battery.
Method used
The protrusion of the limiting component is fixedly connected to the slot of the expansion beam and fixed to the wall of the battery box, avoiding welding and reducing space occupation and the risk of weld damage.
Benefits of technology
The expansion beam assembly reduces the constraints on the internal space of the battery box, reduces the risk of damage to the battery from welding, improves the connection stability between the expansion beam and the limiting component, and enhances the resistance to the expansion of individual battery cells.
