Abstract

The invention discloses an electric air compressor, and belongs to the field of air compressors. The electric air compressor comprises a machine body and a cylinder cover arranged on the machine body.The cylinder cover is provided with an air inlet cavity and an air outlet cavity which is connected with an exhaust port. An air cylinder body, a crank case and a motor support are included. A flow guiding plate is arranged in the air outlet cavity and divides the air outlet cavity into an upper exhaust channel and a lower exhaust channel. A middle circulation hole communicates between the upperexhaust channel and the lower exhaust channel. The exhaust port communicates with the upper exhaust channel. Compressed air inflows from the lower exhaust channel and enters the upper exhaust channelafter passing through the middle circulation hole, and then the compressed air is exhausted from the exhaust port. The air cylinder body, the crank case and the motor support are of an integrated structure, and the center axis of a crank cavity and the center axis of a motor rotation shaft cavity are coaxially arranged. The electric air compressor has the beneficial effects that the work noise ofthe air compressor can be effectively lowered, and coaxiality of a transmission system is guaranteed.

Description

【Technical field】 [0001] The invention relates to an electric air compressor, which belongs to the field of air compressors. 【Background technique】 [0002] Air compressors, especially electric air compressors, are widely used in various fields, such as the field of electric vehicles. Since electric vehicles do not have the noise source of the engine, in this environment, the noise generated by electric air compressors It is more prominent. [0003] The noise of electric air compressors mainly includes aerodynamic noise, mechanical noise and electromagnetic noise. Aerodynamic noise is the main sound source of air compressor noise, which is generated when the air compressor is inhaled and exhausted. The intake noise of the air compressor is reduced by the air filter and the intake muffler, and the reduction of the exhaust noise is the main research topic of all electric air compressor manufacturers. [0004] In addition, the piston air compressors mainly used in the market ...
