The invention discloses a vacuum pump fixing structure and an electric vehicle. The vacuum pump fixing structure comprises an installation support, a fixing assembly and a damping assembly, the installation support comprises a first support body and a second support body, one of the first support body and the second support body is used for being fixed to an automobile body, and the other one of the first support body and the second support body is used for being fixed to a vacuum pump body. A first mounting hole is formed in the first support body, and a second mounting hole is formed in thesecond support body; the fixing assembly comprises a fixing bolt and a locking nut, and the fixing bolt is arranged in the first mounting hole and the second mounting hole in a penetrating mode and matched with the locking nut so as to fixedly connect the first support body and the second support body; and the damping assembly comprises a first damping pad, the first damping pad is arranged outside the fixing bolt in a sleeving mode and located between the first support body and the second support body, and a limiting structure is arranged on the first damping pad so as to limit the first damping pad to move in the radial direction and the circumferential direction of the fixing bolt. The problem that a vacuum pipeline is prone to loosening and air leakage due to large vibration of the vacuum pump is solved.
