The embodiment of the invention relates to a magnesium-aluminum mixed light-weight CCB structure which comprises a die-casting body which is a magnesium alloy integrated die-casting piece. A wire harness supporting bracket is arranged at the upper end of the die-casting body; a knee protection plate mounting bracket, a left lower connecting bracket welding assembly, an auxiliary instrument mounting bracket welding assembly, a right lower connecting bracket welding assembly, a right auxiliary instrument mounting bracket and a right end plate mounting bracket are sequentially arranged at the lower end of the die-casting body; and the left lower connecting bracket welding assembly, the auxiliary instrument mounting bracket welding assembly and the right lower connecting bracket welding assembly are all manufactured by adopting an aluminum alloy stamping process. In the embodiment of the utility model, the CCB structure adopts a light alloy CCB structure with an upper magnesium part and a lower aluminum part, the upper half part adopts a die-casting process, and a transversely arranged three-layer force transmission energy ring system is designed; a triangular force transmission system is formed by combining a plurality of brackets at the lower half part; the production efficiency is high, the product consistency is high, the lightweight degree is high, the weight is reduced by 55% compared with that of a traditional steel tubular beam, and the batch production cost is low.

    本公开实施例是关于一种镁铝混合轻量化CCB结构,包括:压铸本体,为镁合金一体压铸件;压铸本体的上端设有线束支撑支架;压铸本体的下端依次设置有膝部护板安装支架、左下连接支架焊接总成、副仪表安装支架焊接总成、右下连接支架焊接总成、右侧副仪表安装支架和右端板安装支架,且左下连接支架焊接总成、副仪表安装支架焊接总成以及右下连接支架焊接总成均采用铝合金冲压工艺制作而成。本实施例中,CCB结构采用上镁、下铝的轻质合金CCB结构,上半部分采用压铸工艺,设计了横向布置的3层力量传递能量环系统;下半部分多种支架组合成”三角形“力量传递系统;生产效率高、产品一致性高、轻量化程度高,较传统钢制管梁轻量化55%,批量生产成本低。
