The invention relates to a polypropylene vacuum tank for an electric automobile, and belongs to the field of automobile braking. A first vacuum nozzle and a second vacuum nozzle are directly formed in a polypropylene vacuum tank shell in an injection molding mode, a nut is embedded in a tank body, an adapter is installed on the nut, a rubber connecting sleeve is installed on the adapter, polypropylene shell reinforcing ribs are used in the vacuum tank shell to increase the strength of the shell, and the vacuum tank shell is integrally formed in an injection molding mode. The vacuum tank has the advantages that the structure is novel, the shell, the vacuum nozzle and the shell reinforcing ribs of the vacuum tank are made of polypropylene materials, the material cost is reduced, various alarm switches or vacuum sensors of different models can be added by replacing adapters, and the corrosion resistance and the aging resistance during high and low temperature work are improved. Compared with a traditional iron vacuum tank and a traditional nylon vacuum tank, the polypropylene plastic vacuum tank has the advantages that the weight is reduced, the cleanliness can be improved, the injection molding surface roughness is good, the injection molding time is short, the size precision is high, and the consistency is good.

    本发明涉及一种电动汽车用聚丙烯真空罐,属于汽车制动领域。在聚丙烯真空罐壳体上直接注塑出真空嘴一和真空嘴二,在罐体上镶嵌一个螺母,在螺母上安装一个转接头,转接头上安装一个橡胶的连接套,真空罐壳体内部使用聚丙烯壳体加强筋来增加壳体强度,并一体注塑成型。优点是结构新颖,采用聚丙烯材质为真空罐的壳体、真空嘴和壳体加强筋,材料成本降低、更换转接头变可以添加各种不同型号的报警开关或真空传感器、提高耐腐蚀能力和高低温工作时耐老化能力。由于采用了聚丙烯,塑料真空罐与传统的铁材质真空罐和尼龙材质真空罐相比:减轻了重量,并能提高清洁度,注塑成型表面粗糙度好,注塑成型时间短,尺寸精度高且一致性好。
