[0002] The battery bracket assembly is a benchmark product for high-end new energy light commercial vehicles. The battery bracket assembly is suspended on both sides of the vehicle frame beam. It is a carrier for carrying batteries, with high rigidity requirements and stable structure. The battery bracket assembly is an "L"-shaped bracket formed by bending and welding steel plates. The "L"-shaped bracket is a double-groove structure, and the two adjacent "L"-shaped brackets are connected by multiple connecting plates. Inclined plates are welded on the two endmost "L"-shaped brackets to form a triangular structure. The two ends of the inclined plate are bent to one side and overlapped and fixed on the two perpendicular sides of the "L"-shaped bracket to improve the rigidity of the overall frame structure.

[0003] The existing welding processing method uses tooling and auxiliary equipment. The battery bracket assembly has high strength requirements and needs to be welded on both sides. During welding, the battery bracket assembly needs to be flipped at various angles to facilitate the welding operation. The labor intensity is high. Due to the limitations of welding strength and welding time, the daily output is low and cannot meet supply demand.
