Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a dynamic and static disc mechanism, in particular to a dynamic and static disc mechanism of an electric vehicle air-conditioning compressor. Background Art
[0002] The scroll compressor is a compressor with compressible volume, which is composed of a fixed involute scroll and an eccentrically rotating and translating involute scroll. The scroll compressor is composed of two moving and stationary scrolls with double function equation profiles that mesh with each other.
[0003] During the working process of suction, compression and exhaust, the static disk is fixed on the frame, and the dynamic disk is driven by the eccentric shaft and restrained by the anti-rotation mechanism. It rotates in a plane with a very small radius around the center of the static disk base circle. The gas is sucked into the periphery of the static disk through the air filter element. With the rotation of the eccentric shaft, the gas is gradually compressed in several crescent-shaped compression chambers formed by the dynamic and static disks, and then continuously discharged from the axial hole of the central component of the static disk.
[0004] Therefore, when the compressor is working, the moving and stationary plates are subjected to forces such as gas and mechanical friction. The frictional mechanical noise generated can be transmitted through the shell wall that cooperates with the stationary plate and radiated outward. The aerodynamic noise generated is also transmitted and radiated outward at the same time, making the compressor noisier. Utility Model Content

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:
[0007] The utility model provides a dynamic and static disk mechanism of an electric vehicle air-conditioning compressor, comprising a static vortex and a dynamic vortex, wherein the static vortex and the dynamic vortex are connected by a clamping arrangement, a muffler groove is provided on the side wall of the static vortex, a protruding table structure is integrally provided on the inner side wall of the static vortex, and a positioning block is fixed on the inner side of a group of tables and the table bodies opposite thereto, a tooth groove is provided on the inner side wall of the positioning block, a positioning tooth is meshed and fixed in the tooth groove, the positioning tooth and the limit block are an integral structure, the limit block is arranged on the outer side of the vortex plate, the vortex plate is arranged in the static vortex plate, and the dynamic vortex plate is buckled on the outer side of the top end of the vortex plate.
[0008] Furthermore, the silencer grooves are arranged in a plurality of groups side by side, and the silencer grooves are in the shape of a trumpet that is larger on the outside and smaller on the inside.
[0009] Furthermore, the inner side wall of the limit block is an arc-shaped structure, with one side being thicker and the other side being thinner.
[0010] Furthermore, the middle and tail portions of the vortex plate are fixedly connected to the stationary scroll disk, and the front end of the vortex plate is not in contact with the top end of the stationary scroll disk.
[0011] Furthermore, a positioning foot is fixed to the outer side of the movable scroll.
[0012] Furthermore, the width of the muffler groove is not greater than 1 mm.
[0013] Compared with the known public technology, the technical solution provided by the utility model has the following beneficial effects:
[0014] The utility model provides a positioning block and a limiting block structure, wherein the position of the positioning block can be determined according to the head position of the vortex plate, and it is necessary to ensure that the outer side of the outer end of the vortex plate is fixed to the static vortex disk, and the position in the positioning block can be determined by the positioning teeth in the limiting block. When connected, the fixation can be achieved by the meshing of different positioning teeth and tooth grooves, and because they are in different positions, the outer side of the limiting block contacts the position of the vortex plate at different positions. When it is necessary to expand the air intake, the limiting block can be fixed backward, and then the contact position of the limiting block and the vortex plate is placed at the rear end, and the front end of the vortex plate can be expanded outward under its own influence, and when the vortex plate structure on the movable vortex plate contacts, the angle between the two can be expanded, so when external gas enters, the compressed air volume can be expanded at a time, and the limiting block moves forward, which can have the effect of reducing the air intake, and the front end of the vortex plate does not contact the static vortex disk, and when the movable vortex disk contacts the static vortex disk, it does not affect its eccentric movement, thereby compressing the air process.

[0022] The utility model is further described below in conjunction with embodiments.
[0023] Embodiment: A dynamic and static disk mechanism of an electric vehicle air conditioning compressor, referring to the attached Figure 1 -Attached Figure 3 , comprising a stationary scroll 1 and a movable scroll 2, wherein the stationary scroll 1 and the movable scroll 2 are connected by a clamping arrangement, a muffler groove 11 is provided on the side wall of the stationary scroll 1, a protruding platform structure is integrally provided on the inner side wall of the stationary scroll 1, and a positioning block 3 is fixed on the inner side of a group of platforms and the platforms opposite thereto, a tooth groove 31 is provided on the inner side wall of the positioning block 3, a positioning tooth 41 is meshed and fixed in the tooth groove 31, the positioning tooth 41 and the limit block 4 are an integral structure, the limit block 4 is arranged on the outer side of the vortex plate 12, the vortex plate 12 is arranged in the stationary scroll 1, and the movable scroll 2 is buckled on the outer side of the top end of the vortex plate 12;
[0024] The silencer grooves 11 are arranged in a plurality of groups in parallel, and are trumpet-shaped with a large outside and a small inside. The trumpet-shaped structure with a large outside and a small inside can reduce the external air pressure, and the air can enter the interior of the vortex disk after being accelerated by the structure.
[0025] The inner wall of the limit block 4 is an arc-shaped structure, and one side is thick and the other side is thin; the middle and tail parts of the vortex plate 12 are fixedly connected to the static vortex disk 1, and the front end of the vortex plate 12 does not contact the top of the static vortex disk 1; a positioning foot is fixed on the outer side of the movable vortex disk 2; the width of the muffler groove 11 is not more than 1mm; through the provided positioning block 3 and the limit block 4 structure, the position of the positioning block 3 can be determined according to the head position of the vortex plate 12, and it is necessary to ensure that the outer side of the outer end of the vortex plate 12 is fixed with the static vortex disk 1. The position in the positioning block 3 can be determined by the positioning teeth 41 in the limit block 4. When connected, the different positioning teeth 41 and tooth grooves 31 can be used. The limit block 4 is meshed to achieve fixation, and because it is in different positions, the outer side of the limit block 4 contacts the position of the vortex plate 12 at different positions. When the air intake needs to be expanded, the limit block 4 can be fixed backward, and then the contact position of the limit block 4 and the vortex plate 12 is placed at the rear end. The front end of the vortex plate 12 can be expanded outward due to its own influence. When the vortex plate 12 structure contacts the movable scroll 2, the angle between the two can be expanded. Therefore, when external gas enters, the amount of compressed air can be expanded at a time, and the limit block 4 moves forward, which can have the effect of reducing the air intake. The front end of the vortex plate 12 does not contact the fixed scroll 1. When the movable scroll 2 contacts the fixed scroll 1, it does not affect its eccentric movement, thereby compressing the air.
