Integrated type car air filter system

Abstract

The invention belongs to the technical field of air filters, and provides an integrated type car air filter system. The system comprises an air filter chamber, an air inlet buffer chamber, an air suction buffer chamber, a filter element, an air inlet pipe and an air suction pipe. The air filter chamber comprises a filter chamber upper shell and a filter chamber lower shell, a first flange type communication opening is formed in the filter chamber upper shell, a second flange type communication opening is formed in the filter chamber lower shell, the air inlet buffer chamber is fixedly connected with the filter chamber upper shell, the air inlet buffer chamber communicates with the first flange opening communication opening, the air suction buffer chamber is fixedly connected with the filter chamber lower shell, the air suction buffer chamber communicates with the second flange communication opening, the filter element is arranged between the filter chamber upper shell and the filter chamber lower shell, and the air inlet pipe and the air suction pipe communicate with the air inlet buffer chamber and the air suction buffer chamber correspondingly. The system is reasonable in whole structure design, small in occupied space, high in integration, capable of greatly saving the space of a forward engine room, and more suitable for forward engine room layout of an extended-range electric car.

Description

technical field [0001] The invention belongs to the technical field of air filters, and in particular relates to an integrated automobile air filter system. Background technique [0002] At present, the structure of the air filter system of a traditional passenger car is usually provided with an air filter chamber. The upper cover chamber of the air filter chamber is provided with an air inlet, and the lower cover chamber of the air filter chamber is provided with an air outlet. It is connected with the intake pipe that inhales natural air, and the air outlet is connected with the intake pipe connected to the engine throttle. In order to reduce intake noise and adjust the rationality of engine intake, the air intake of the air filter chamber is connected to the intake buffer chamber through a rubber hose, and the intake buffer chamber is connected to the intake pipe, and the air outlet of the air filter chamber is also connected through a rubber hose There is a suction buff...

Problems solved by technology

[0003] The advantage of this air filter system is that the length and bending angle of the rubber hoses connected between the two buffer chambers and the air filter chamber can be adjusted arbitrarily according to the needs, which is suitable for the layout of the front cabin of a traditional car. The disadvantage is that it is bulky Furthermore, it takes up a lot of space. Although it takes up a lot of space, the air filter system of this structure still meets the needs of traditional passenger cars. However, if the mechanical functions of the front cabin of passenger cars are added, the traditional air filter system will It is difficult for the device system to meet the design needs

For example, in order to realize the proper functions of an extended-range electric vehicle, in addition to arranging the traditional engine system and removing the gearbox to install a generator in the front cabin, it is also necessary to add an electric air conditioning system, an electric brake booster system, a high-voltage electrical box, Electronic water pump and other components occupy a lot of space in the front cabin. If the traditional air filter system is used, the space in the front cabin will be insufficient. If the front cabin is enlarged, the manufacturing cost of the whole vehicle will be directly increased.
