Abstract

The invention relates to the technical field of vacuum pumps, in particular to an electric vacuum pump and a brake assisting system. The electric vacuum pump comprises a pump body, wherein a pump bodyoutlet is formed in the pump body, a drainage pipeline is connected to the pump body outlet and is provided with a pipeline outlet, the pipeline outlet faces the pump body, and a guide cover structure for increasing a spraying area of the pipeline outlet is arranged at the pipeline outlet. By means of the electric vacuum pump, the overflow rate of heat accumulated in the electric vacuum pump is accelerated, a condition that the electric vacuum pump generates heat severely and is too high in temperature as heat is accumulated is avoided, stable operation of the electric vacuum pump is guaranteed and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to an electric vacuum pump and a brake booster system. Background technique [0002] In recent years, with the country's increasing emphasis on the ecological environment, green vehicles such as electric vehicles and hybrid vehicles have gradually entered the public's field of vision. Electric vehicles / hybrid vehicles usually include driving devices, steering systems, braking systems, brake booster systems, etc. The brake booster system is mainly a vacuum brake booster system, which mainly includes an electric vacuum pump and a vacuum booster. [0003] During the driving process of the vehicle, in order to ensure the performance of the brake booster, the electric vacuum pump needs to run continuously. However, due to the internal friction of the electric vacuum pump that has been running for a long time, heat accumulation will occur, which will cause the temperature of the ele...
