Problems solved by technology

Because the material strength and compactness of ordinary cast aluminum alloy parts are not high compared with high-strength aluminum alloys such as forging or extrusion casting, the thread 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

Embodiment Construction

[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals denote the same or similar structures in the drawings, and thus their repeated descriptions will be omitted.

[0038] In order to improve the defects of the prior art, the present invention provides a compressor, preferably an electric scroll compressor for vehicles. In the following, various embodiments will be described by taking a vertical compressor, that is, a compressor in which the axis of the shaft transmission mechanism and the scroll pump body is vertically arranged, but the present invention is also applicable to a horizonta...

Abstract

Provided is a compressor, comprising: a housing (3), which is provided with an accommodation space; a compression mechanism, which comprises a static scroll plate (2) comprising a low-pressure side (202) provided with scroll teeth (201) and a high-pressure side (206) facing away from the scroll teeth (201), and a movable scroll plate (15) located in the accommodation space, wherein a side of the movable scroll plate (15) provided with scroll teeth (1501) is opposite the scroll teeth (201) of the static scroll plate (2), and the scroll teeth (201) of the static scroll plate (2) and the scroll teeth (1501) of the movable scroll plate (15) form a compression cavity; an electric motor mechanism, which is accommodated in the accommodation space, comprises an electric motor rotor (20) and an electric motor stator (12), and drives the movable scroll plate (15) to rotate relative to the static scroll plate (2), so as to compress refrigerant in the compression cavity; an upper support (11), which is connected and fixed to the low-pressure side (202) of the static scroll plate (2); and a lower support (13), which is connected and fixed to the upper support (11) via the electric motor stator (12). The compressor has the advantages of high reliability and low noise.

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...
