Problems solved by technology

At present, the common problem in the field of electric vehicles is that the battery life of electric vehicles is limited, which limits the promotion and application of electric vehicles
[0003] The B-pillar connection structure of the side wall of the existing electric vehicle body is formed by stamping steel plates, mainly composed of the B-pillar assembly, the threshold beam assembly and the top edge beam. The forming process is complicated and the cost is high. The weight of the surrounding and rear structure is not conducive to the lightweight of electric vehicles, and cannot effectively extend the cruising range of electric vehicles, and the production, assembly and maintenance costs of metal parts are high, which is not conducive to reducing costs and cannot meet the requirements of energy conservation and environmental protection
