The invention discloses an automatic dust removal device for an electric drive system of an electric passenger car, comprising an air pump, an air storage device, an automatic exhaust valve, a two-position four-way electromagnetic valve, a regulating valve, a gas nozzle device, an exhaust device and the like. The air pump is connected with the gas storage device through the pipeline, and the gas storage device is connected with the brake gas circuit, the automatic exhaust valve and the two-position four-way solenoid valve; the design of the present invention is simple and reasonable. Frequent braking and door opening and closing, the air pump is always in an intermittent working state, and the pressure of the gas storage device fluctuates. Gas, resulting in the waste of electric energy when the gas source and the air pump are working. In this plan, when the air pump is working, the gas discharged from the exhaust valve when the pressure of the gas storage device is high is used reasonably for the automatic dust removal of the vehicle, which not only saves At the same time, the floating dust in the electric drive system room has also been removed.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, and relates to an internal dust removal device of an automobile, in particular to an automatic dust removal device for an electric drive system of an electric passenger car. Background technique [0002] At present, due to the increasing popularity of electric vehicles and the promotion of public transportation in cities. More and more parts of new energy vehicles are used in electric vehicles, such as electric vehicle high-voltage power distribution system, motor driver, three-in-one system (steering inverter, air pump inverter, vehicle DC / DC DC charger), Electronic water pumps and other equipment are essential components. Most of these equipment work under high voltage and high current conditions. During the working process, there will be temperature rise, which will cause the air around it to expand with heat and contract with cold, and dust and particles in the air will be removed. ...
