AI Technical Summary

Technical Problem

The existing riveted structure of the battery box occupies internal space, resulting in reduced space utilization and, under limited space conditions, cannot improve the local connection strength, thus affecting the overall strength.

Method used

Design an embedded reinforcing block for a battery box. Through the combination structure of an embedded plate and a vertical plate, the side beam and the cross beam are connected by rivets and bolts. The embedded plate is fixed in the groove of the side beam, and the vertical plate is inserted into the cavity channel of the cross beam and fixed by rivets and bolts to form a firm connection.

Benefits of technology

It improves the space utilization and overall strength of the battery box, enhances connection strength, reduces production costs, and improves assembly efficiency.
