Embodiment 1

[0029] In a typical embodiment of the present invention, such as figure 1 As shown, this embodiment discloses an electric air compressor air filter air intake device for passenger cars. Based on the cleaner air environment of the roof air quality than the rear compartment, this embodiment selects the roof as the air intake position. The top air intake structure is used to realize the roof air intake function, and the air drying process in the air intake device is completed through the combination of the three-way structure diverter and the duckbill valve 6.

[0030] The electric air compressor 8 air filter air intake device for passenger cars in this embodiment specifically includes an air intake cover installed on the roof, and a limit snap ring structure is used at the entrance of the air intake pipe 11 to prevent dripping on the roof cover. The rainwater on the skin splashes into the air intake pipe 11; the bottom of the protective cover adopts a honeycomb structure to prev...

Embodiment 2

[0042] In a typical implementation of the present invention, this embodiment discloses a passenger car, including the electric air compressor 8 air filter air intake device for passenger cars as described in Embodiment 1, and also includes a passenger car body, the The electric air compressor 8 air filter air intake device for passenger cars is installed on the passenger car body.

[0043] Taking the door of the bus body as an example, the door is connected to the electric air compressor 8 to realize opening and closing. , and the first port 311 of the electric air compressor 8 communicates with the second port 321 of the air filter through the third intake hose 7, and the first port 311 of the air filter communicates with the splitter through the second intake hose The second branch pipe 32 of the flow divider communicates with the bottom port of the intake pipe 11 through the first intake hose 2 .

[0044] In this embodiment, the first hose, the second hose and the third ho...

Abstract

The invention discloses an air inlet device of an air filter of an electric air compressor for a passenger car and the passenger car, and belongs to the field of electric passenger cars. The air inletdevice can improve the quality of air entering the electric air compressor of the new energy passenger car, and solves the problem of frequent replacement of a filter element. The air inlet device comprises a flow divider and an air inlet cover, wherein a plurality of ports are formed in the flow divider; the air inlet cover communicates with the first port of the flow divider; the second port ofthe flow divider is used for communicating with the air filter; the third port of the flow divider communicates with a duckbill valve; and honeycomb-shaped small holes are formed in the end surface of the bottom of the air inlet cover.

Description

technical field [0001] The invention belongs to the field of electric passenger cars, and in particular relates to an air intake device for an electric air compressor air filter for passenger cars and a passenger car. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The air compressor for passenger cars is an important part of the passenger car. The brakes, door pump, clutch cylinder and air suspension of the passenger car all need the support of the air compressor. Especially in the braking system of passenger cars, air pressure braking is the most common form of dynamic braking system. It has a large braking force and is easy to use. It is widely used in large and medium-sized passenger cars. Existence, the engine drives the air compressor through gear transmission, the air compressor generates compressed air, and the high-pressure air drives the...
