The electric automobile vacuum pipeline device comprises a first pipeline, a second pipeline, a third pipeline, a first gas circulation piece and a three-way pipe, and the three-way pipe comprises a first pipe opening, a second pipe opening and a third pipe opening; one end of the first pipeline communicates with the first pipe orifice, and the other end of the first pipeline communicates with the vacuum tank; one end of the second pipeline communicates with the second pipe orifice, and the other end of the second pipeline communicates with a vacuum pump; one end of the third pipeline is communicated with the third pipe orifice, and the other end of the third pipeline is communicated with a vacuum booster; the first gas circulation piece is arranged in the third pipeline, and the first gas circulation piece and the third pipeline are integrally formed. Due to the fact that the first gas circulation piece and the third pipeline are directly and integrally formed, on one hand, assembling steps are reduced, and on the other hand, the gas tightness of the pipeline is guaranteed.
本发明涉及了一种电动汽车真空管路装置及电动汽车,包括第一管路、第二管路、第三管路、第一气体流通件以及三通管,三通管包括第一管口、第二管口以及第三管口;第一管路的一端连通第一管口,第一管路的另一端用于连通真空罐;第二管路的一端连通第二管口,第二管路的另一端用于连通真空泵;第三管路的一端连通第三管口,第三管路的另一端用于连通真空助力器;第一气体流通件设置在第三管路内,第一气体流通件与第三管路一体成型。由于第一气体流通件直接与第三管路一体成型,一方面减少了装配步骤,另一方面管路的气密性也得以保证。
