a compressor

Abstract

The invention discloses a compressor. The compressor comprises a shell, a compression mechanism, an upper support, a motor mechanism and a lower support, wherein the compression mechanism comprises a static scroll and a dynamic scroll; the shell is provided with a first opening and a containing space, and the first opening is located on one side of the containing space; the static scroll comprises a low-pressure side and a high-pressure side, wherein the low-pressure side is provided with vortex teeth, and the high-pressure side backs onto the vortex teeth; the dynamic scroll is located in the containing space, the side, provided with vortex teeth, of the dynamic scroll is opposite to the vortex teeth of the static scroll, and the vortex teeth of the static scroll and the vortex teeth of the dynamic scroll form a compression cavity; the upper support is fixedly connected to the low-pressure side of the static scroll; the motor mechanism is contained in the containing space, comprises a motor rotor and a motor stator and drives the dynamic scroll to rotate relative to the static scroll so as to compress refrigerants in the compression cavity, wherein the motor stator is connected and fixed to the upper support; and the lower support is located on the side, away from the first opening, of the containing space, serves as a part of the shell and is integrally formed with the shell.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a vehicle compressor. Background technique [0002] Existing scroll compressors for vehicles have the following characteristics and deficiencies: [0003] 1) Basically, the stator of the motor is interference-fitted to the inner wall of the housing, and the vibration noise generated by the motor when the compressor is running is easily transmitted directly through the housing. [0004] 2) The die-casting aluminum alloy shell blank is used, and the finished shell is obtained through more machining (processing parts include the end face of the shell, the inner hole of the shell and the motor interference assembly, the bearing seat hole and the end face, etc.). Since die-casting parts are easy to produce air holes, if the machined parts of the die-casting shell have a large area or many parts, the air holes may be penetrated during the processing process, resulting in poor airtightness o...

AI Technical Summary

Problems solved by technology

Compared with high-strength aluminum alloys such as forging or extrusion casting, ordinary cast aluminum alloy parts have low material strength and compactness, and the threaded teeth of the suction or exhaust pressure plate are easily damaged.

[0006] 4) The shape and structure of the existing compressors are basically cylinder-like. Although there will be some narrow space around the compressor body when it is installed on the car, it is difficult to arrange other parts

Therefore, the utilization efficiency of the installation space is not high
