The invention discloses an electronic vacuum pump for a new energy vehicle brake vacuum booster. The electronic vacuum pump comprises a motor assembly, a supporting base, a pump chamber lower cover, a driving sleeve, a pump rotor, blades, a pump chamber, a pump chamber upper cover, a pump body cover and fixing pins, wherein a left side air feeding slot of the pump chamber lower cover, a left side air feeding through hole of the pump chamber and a left side air feeding slot of the pump chamber upper cover are communicated with one another to form an air passageway; a right side air feeding slot of the pump chamber lower cover, a right side air feeding through hole of the pump chamber and a right side air feeding slot of the pump chamber upper cover are communicated with one another to form an air passageway; a flow guide slot of the pump chamber lower cover is communicated with an inner cavity of the pump chamber; an air discharging slot of the pump chamber upper cover is communicated with the inner cavity of the pump chamber; the flow guide slot of the pump chamber lower cover and the air discharging slot of the pump chamber upper cover are symmetric. When the vacuum pump works, an air path with four air inlets and two air outlets is formed; therefore, the air feeding resistance is greatly reduced, and the air feeding amount of the pump chamber is increased; under the equal energy consumption, the vacuumizing efficiency of the vacuum pump provided by the invention is higher.
Description
technical field [0001] The invention relates to a vacuum pump, in particular to an electronic vacuum pump for a new energy vehicle brake vacuum booster. Background technique [0002] There are two types of vacuum pumps used in domestic gasoline and diesel engine vehicles. One is mechanical vacuum pumps, which rely on engines to provide power. This type of vacuum pumps is currently produced by some domestic manufacturers and has gradually matured; the other is electronic vacuum pumps. Vacuum pumps rely on their own motors to provide power. At present, domestic automobile manufacturers basically import this type of vacuum pumps, especially imported German products; According to market feedback, there are no mature products, let alone domestic products that have achieved mass production and large-scale sales. [0003] As the country focuses on promoting the research and development of new energy vehicles and encourages the development of new energy vehicles, our company found ...
