Automotive air conditioner compressor shell structure

The invention discloses an automotive air conditioner compressor shell structure. The automotive air conditioner compressor shell structure comprises a shell body, and the shell body is provided withmultiple compressor installing supporting lugs; a first rib plate and a second rib plate are arranged on the inner side face of the bottom of the shell body, the first rib plate and the second rib plate are perpendicular to each other to form a cross-shaped partition rib, and the two sides of the first rib plate and the two sides of the second rib plate are connected with the inner wall of the shell body separately; an annular rib which axially extends along the shell is arranged among the cross-shaped partition rib formed by the first rib plate and the second rib plate, and four fan-shaped sound insulation cavities are formed between the annular rib and the cross-shaped partition rib and used for dispersing impact of high-pressure gas in the shell; and an arc-shaped rib is arranged at thebottom of the shell, and the two ends of the arc-shaped rib extends to the compressor installing supporting lugs. According to the automotive air conditioner compressor shell structure, the strengthand the rigidity of the bottom of the shell are improved, shell bottom noise caused by mechanical vibration is reduced, impact of gas pulsation to the shell bottom is dispersed through height difference formed among the fan-shaped sound insulation cavities and formed between the sound insulation cavities and an exhaust port, and noise generated by compressors is reduced.
