AI Technical Summary
Traditional flanged and riveted battery top cover design suffers from multiple steps, resulting in low production efficiency, high equipment investment, high labor costs, insufficient mechanical strength, poor sealing, and low safety.
The battery top cover adopts a new type of flanged riveting design, which includes a base plate, terminal post, sealing ring, insulating plate and steel ring. By optimizing the structure and assembly method, the riveting steps are reduced, the mechanical strength and sealing performance are enhanced, and the mechanical interlocking and anti-rotation function are achieved by using the convex ring, groove and limiting structure of the terminal post.
It improved production efficiency, reduced manufacturing costs, enhanced mechanical strength and sealing, reduced the risk of battery failure, and improved safety.
