Horizontal scroll compressor for vehicle and pump body assembly thereof

Abstract

The invention relates to the technical field of compressors and provides a horizontal scroll compressor for a vehicle and a pump body assembly thereof. The pump body assembly comprises a stationary vortex plate provided with a fixed scroll, a movable vortex plate provided with a rotating screen forming a working cavity with the fixed scroll, a bracket supported on the back surface of the movable vortex plate and an eccentric crankshaft which is arranged in an axle hole of the movable vortex plate in a penetrating manner. The pump body assembly also comprises a plurality of groups of anti-rotation mechanisms which are circumferentially arranged between the movable vortex plate and the bracket in a spaced manner, the anti-rotation mechanisms are formed by pin structures stretching into roundholes, and the pin structures are in tangential fit with the round holes to limit circumferential rotation of the movable vortex plate; the pin structures are mounted on the end surface of the bracket, and the round holes are formed in the back surface of the movable vortex plate; or the pin structures are mounted on the back surface of the movable vortex plate and the round holes are formed in the end surface of the bracket. By matching the pin structures mounted on the back surface of the movable vortex plate or the end surface of the bracket with the round holes directly formed in the endsurface of the bracket or the back surface of the movable vortex plate tangentially, an anti-rotation function of the movable vortex plate is achieved. The horizontal scroll compressor is high in reliability and convenient to match, and noise and cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a horizontal scroll compressor for vehicles and a pump body assembly thereof. Background technique [0002] The horizontal scroll compressor for vehicles is installed in the air-conditioning system of the vehicle for cooling and heating of the vehicle. At present, an anti-rotation mechanism with anti-rotation pins and slip rings is widely used in horizontal scroll compressors for vehicles. The anti-rotation pin is installed on one mating part of the compressor, and the slip ring is installed in the opening of the other mating part. During the working process of the compressor, the anti-rotation pin is in contact with the sliding line of the slip ring, which will cause the following problems. [0003] First, the lubrication conditions between the anti-rotation pin and the slip ring are relatively harsh. In the case of frequent start-up and stop of the compressor, and startin...

AI Technical Summary

Problems solved by technology

[0003] First, the lubrication conditions between the anti-rotation pin and the slip ring are relatively harsh. In the case of frequent start-up and stop of the compressor, and starting after a long period of standby, there is not enough lubricating oil between the anti-rotation pin and the slip ring, resulting in serious wear , affecting the life of the compressor;

[0004] Second, the contact between the anti-rotation pin made of metal material and the sliding line of the slip ring produces a large noise, which increases the noise of the compressor;

[0005] Third, the coordination between the anti-rotation pin and the slip ring is highly demanding, and the number of parts is large, which increases the complexity of compressor assembly and manufacturing costs
