Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and specifically to a highly wear-resistant scroll air-conditioning compressor assembly. Background Art

[0002] A scroll compressor is a positive displacement compressor. By the relative rotation of two mutually meshing spiral scroll disks (a moving disk and a stationary disk), a continuously decreasing sealed cavity is formed to compress gas. It is widely used in air conditioners, refrigeration equipment, and the thermal management system of new energy vehicles, and has the advantages of high reliability and energy conservation.

[0003] In the prior art, the Chinese invention with the publication number CN110878751B discloses a scroll compressor, which can ensure the stable supply of lubricating oil to the thrust surface under any working conditions, and actively suck and eject lubricating oil by using the pressure difference, greatly increasing the supply amount of lubricating oil and significantly improving the oil supply and lubrication performance between the end face of the moving scroll disk and the thrust surface of the thrust plate.

[0004] However, currently, when the moving scroll disk and the stationary scroll disk of the scroll compressor rotate relative to each other, the end face of the scroll disk will be continuously rubbed. After long-term use, the sealing performance is likely to be reduced due to frictional wear, thus affecting the compression performance of the compressor. Therefore, the present invention proposes a highly wear-resistant scroll air-conditioning compressor assembly to solve the above problems. Summary of the Invention

Detailed implementation manners

[0019] In order to clearly and completely describe the objectives, technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 11 , the present invention provides a technical solution: Embodiment 1, a highly wear-resistant scroll air-conditioning compressor assembly, comprising: an outer shell 1 and a moving disk seat 2.

[0021] Specifically, a static disk seat 3 fixedly connected thereto is provided in the upper inner cavity of the outer shell 1. The connection between the static disk seat 3 and the outer shell 1 is a detachable fixed connection, and the connection structure between the two will be described in detail later. A through groove is vertically penetrated through the middle of the static disk seat 3 to form a static scroll disk 31, as Figure 6As shown, the through groove formed in the middle of the static disk seat 3 and the formed static scroll disk 31 are both in a spiral structure, and the upper and lower end faces of the static disk seat 3 and the static scroll disk 31 are kept flush. A connecting disk 4 is arranged above the static disk seat 3, and there is a gap between them. The connecting disk 4 and the static disk seat 3 are kept close to each other through the cooperation of bolts and tension nuts 57, and a compression spring 58 for pressing the connecting disk 4 is arranged between the tension nut 57 and the connecting disk 4. Since there is a certain gap between the connecting disk 4 and the static disk seat 3, the connecting disk 4 can move closer to or away from the static disk seat 3 within a certain distance. The setting of the compression spring 58 is used to apply a pressing force to the connecting disk 4, so that the connecting disk 4 always has a tendency to move closer to the static disk seat 3. A pressing disk 5 is arranged below the connecting disk 4, and the pressing disk 5 and the connecting disk 4 are connected to each other, and their connection structure will be described in detail later. The pressing disk 5 is located in the through groove formed in the middle of the static disk seat 3. When the connecting disk 4 moves, it can drive the pressing disk 5 to move accordingly, so that the pressing disk 5 can move up and down in the through groove formed in the middle of the static disk seat 3; Secondly, the moving disk seat 2 is located below the static disk seat 3. The upper surface of the moving disk seat 2 is fixed with a moving scroll disk 21. The moving scroll disk 21 is located in the through groove formed in the middle of the static disk seat 3 and is staggered with the static scroll disk 31. When the moving scroll disk 21 and the static scroll disk 31 move relative to each other, the air at their edges is gradually squeezed and compressed towards the center, so that the air pressure can gradually increase. A driving disk 22 is arranged below the moving disk seat 2, and an annular seal 23 is adhesively fixed at the edge between them. The setting of the annular seal 23 is used to ensure that the gap between the moving disk seat 2 and the driving disk 22 is in a sealed state. A through hole 24 is formed in the middle of the moving disk seat 2. The high-pressure gas between the moving scroll disk 21 and the static scroll disk 31 enters the gap between the moving disk seat 2 and the driving disk 22 through the through hole 24. Since the through hole 24 is located in the middle of the moving disk seat 2 and the gas here has been compressed to the maximum air pressure state, the high-pressure gas can push the moving disk seat 2 from bottom to top to keep the lower end face of the static disk seat 3 tightly attached, and the moving scroll disk 21 presses the lower surface of the pressing disk 5 from bottom to top, as Figure 3 and Figure 7 shown. Combining with the existing well-known technology, it can be known that when the moving scroll disk 21 and the static scroll disk 31 move relative to each other, the air pressure at their centers is greater than that at their edges. By forming a through hole 24 at the center of the moving disk seat 2 and introducing part of the high-pressure gas into the gap between the moving disk seat 2 and the driving disk 22, the moving disk seat 2 can always be tightly attached to the lower surface of the static scroll disk 31, and at the same time, the upper end face of the moving scroll disk 21 is always tightly attached to the lower surface of the pressing disk 5. That is to say, even if the end faces of the moving scroll disk 21 and the static scroll disk 31 generate frictional loss during use, this device can automatically adjust their relative positions in the vertical direction through high-pressure gas, ensure that the cavity between them is always in a sealed state, and avoid gas leakage.

[0022] To avoid excessive deformation and damage of the annular seal 23, the present application further has a retaining ring 25 fixed at the edge of the lower surface of the moving disk seat 2, and the retaining ring 25 covers the outside of the annular seal 23 and the driving disk 22. The setting of the retaining ring 25 is used to limit the annular seal 23. Since there is high-pressure gas filled between the moving disk seat 2 and the driving disk 22, the annular seal 23 will undergo elastic deformation and bulge outwards under the action of the high-pressure gas. At this time, the retaining ring 25 just abuts against the outer wall of the annular seal 23, avoiding excessive deformation of the annular seal 23 and resulting in its own rupture. A telescopic member 26 is provided between the moving disk seat 2 and the driving disk 22, and both ends of the telescopic member 26 are fixedly connected to the moving disk seat 2 and the driving disk 22 respectively. The telescopic member 26 is a telescopic rod. The setting of the telescopic member 26 can, on the one hand, limit the distance between the moving disk seat 2 and the driving disk 22, and on the other hand, prevent relative rotation between the moving disk seat 2 and the driving disk 22.

[0023] To ensure that the moving scroll disk 21 and the pressing disk 5 always remain in close contact, the present application further has a partition plate 51 provided between the pressing disk 5 and the connecting disk 4. A spiral elastic member 56 is fixed on the surface of the partition plate 51. The elastic member 56 is wavy along its own length direction and abuts against the connecting disk 4 on the upper side. The elastic member 56 is located between the partition plate 51 and the connecting disk 4 and is squeezed by both of them. The elastic member 56 itself can undergo elastic deformation, thereby pushing the partition plate 51 to always have a tendency to move closer to the pressing disk 5. A tension bolt 53 is fixed on the surface of the pressing disk 5, and the upper end of the tension bolt 53 sequentially passes through the partition plate 51, the elastic member 56 and the connecting disk 4 movably. The upper end of the tension bolt 53 tightens the connecting disk 4 through a nut. Since the pressing disk 5 and the connecting disk 4 are tightened by the tension bolt 53, the thrust provided by the elastic member 56 makes the pressing disk 5 and the connecting disk 4 always have a tendency to move away from each other. When the moving scroll disk 21 squeezes the lower surface of the pressing disk 5 from bottom to top, the compression spring 58 can push the connecting disk 4 to move downward, and the elastic member 56 can push the pressing disk 5 to move downward, thereby ensuring that the pressing disk 5 can always remain in close contact with the moving scroll disk 21. In addition, vortex grooves 55 for the stationary scroll disk 31 to pass through are respectively formed through the surfaces of the partition plate 51 and the pressing disk 5. That is to say, both the partition plate 51 and the pressing disk 5 can perform displacement in the vertical direction in the through groove formed in the middle of the stationary disk seat 3.

[0024] To improve the sealing performance of this device, the present application further has a cushion plate 531 fixed to the lower end of the tension bolt 53, and the cushion plate 531 is placed between the pressing plate 5 and the partition plate 51. A sealing layer is also provided on the surface of the cushion plate 531. When the partition plate 51 approaches the pressing plate 5 under the thrust of the elastic member 56 and presses the cushion plate 531, the sealing layer on the surface of the cushion plate 531 can effectively improve the sealing performance between the two, preventing gas between the two from leaking along the surface of the tension bolt 53. A sealing strip 52 is adhesively fixed between the pressing plate 5 and the partition plate 51 at the opening edge of the scroll groove 55. As Figure 5 shown, the sealing strip 52 actually includes two spiral structures, and the head and tail of these two spiral structures are correspondingly connected to form a complete whole. Since the stationary scroll plate 31 passes through the scroll groove 55 and the sealing strip 52 corresponds to the opening edge of the scroll groove 55, the side surface of the sealing strip 52 can be kept in close contact with the stationary scroll plate 31, thereby preventing gas between the stationary scroll plate 31 and the moving scroll plate 21 from leaking between the stationary scroll plate 31 and the scroll groove 55. In addition, an exhaust pipe 54 is fixed to the middle of the pressing plate 5, and the lower end of the exhaust pipe 54 communicates with the middle of the inner cavity of the stationary disk seat 3. A communication port 541 is provided on the surface of the exhaust pipe 54, and the communication port 541 communicates with the gap between the pressing plate 5 and the partition plate 51. Since the exhaust pipe 54 communicates with the center between the moving scroll plate 21 and the stationary scroll plate 31, where the gas pressure reaches the maximum and is high-pressure gas, the high-pressure gas can enter the gap between the pressing plate 5 and the partition plate 51 through the communication port 541. Under the action of the high-pressure gas, the sealing strip 52 will undergo elastic deformation and thus press and fit on the stationary scroll plate 31 to prevent a gap from being generated between the stationary scroll plate 31 and the scroll groove 55, resulting in gas leakage between the moving scroll plate 21 and the stationary scroll plate 31, thereby effectively improving the sealing performance of this device.

[0025] To drive the orbiting scroll disk 21 to perform rotational displacement, the present application further includes a drive shaft 6 rotatably installed in the middle of the inner cavity of the housing 1. An eccentric plate 61 is fixed to the upper end of the drive shaft 6, and an eccentric shaft 62 is fixed to one end of the eccentric plate 61. The axis of the eccentric shaft 62 is parallel to and offset from the axis of the drive shaft 6. The drive shaft 6 can rotate by itself. When the drive shaft 6 rotates, it drives the eccentric shaft 62 to rotate through the eccentric plate 61. However, since the axis of the eccentric shaft 62 is offset from the axis of the drive shaft 6, the eccentric shaft 62 will rotate around the axis of the drive shaft 6. The eccentric shaft 62 is rotatably installed on the middle of the lower surface of the drive disk 22 through a bearing member 64. When the drive shaft 6 rotates, the eccentric shaft 62 can drive the drive disk 22, the orbiting disk seat 2, and the orbiting scroll disk 21 to perform displacement, and the direction of its displacement is to rotate around the axis of the drive shaft 6, thereby realizing the compression of the gas between the orbiting scroll disk 21 and the stationary scroll disk 31. A rotation prevention sleeve 221 is fixedly arranged at the edge of the lower surface of the drive disk 22, and the rotation prevention sleeve 221 is in the shape of a hollow strip. A rotation prevention boss 13 that is slidably connected to it is inserted into the inner cavity of the rotation prevention sleeve 221. One end of the rotation prevention boss 13 is fixed with a fixed seat 12, and the fixed seat 12 is fixedly connected to the inner wall of the housing 1. The cooperation between the rotation prevention sleeve 221 and the rotation prevention boss 13 is used to limit the drive disk 22 to prevent the drive disk 22 from rotating by itself. That is to say, the drive disk 22, the orbiting disk seat 2, and the orbiting scroll disk 21 of the present device can only perform rotational displacement (revolution) around the drive shaft 6 and will not rotate (rotate by itself).

[0026] To facilitate the installation of the bearing member 64 and ensure its stability after installation, the present application further includes a stepped ring 222 fixedly arranged in the middle of the lower surface of the drive disk 22. A lower baffle 63 is movably sleeved outside the eccentric shaft 62, and the lower baffle 63 is fixedly connected to the stepped ring 222 through bolts. A bearing groove 631 for installing the bearing member 64 is opened in the middle of the lower baffle 63. An upper baffle 65 is attached to the upper end of the eccentric shaft 62. A polygonal slot 621 is opened on the upper end surface of the eccentric shaft 62. A polygonal insert 651 is fixed to the lower surface of the upper baffle 65, and the polygonal insert 651 is movably inserted into the inner cavity of the polygonal slot 621 and is adapted to it. The upper baffle 65 is fixedly connected to the eccentric shaft 62 through bolts. The upper baffle 65 presses the upper side of the bearing member 64. Combining Figure 8 and Figure 9 As can be seen, the eccentric shaft 62 and the drive disk 22 are relatively rotatably connected through the bearing member 64, and the two will not separate from each other. After the lower baffle 63 is fixedly connected to the drive disk 22 using bolts, the inner wall of the bearing groove 631 can limit the lower side of the bearing member 64. Coupled with the limitation of the upper side of the bearing member 64 by the upper baffle 65, the bearing member 64 and the eccentric shaft 62 are prevented from separating from each other, thereby ensuring the stability of the connection between the drive shaft 6 and the drive disk 22 and enabling the drive shaft 6 to stably drive the orbiting disk seat 2 to perform rotational displacement.

[0027] To seal the housing 1, the present application further includes a top cover 7 covering the upper opening of the housing 1, and the two are fixedly connected by bolts. The top cover 7 has a convex hollow structure, and a sound-absorbing plate 71 is fixedly arranged inside the cavity of the top cover 7. The sound-absorbing plate 71 is provided to absorb and reduce the noise generated during the operation of the device, avoiding noise pollution. An exhaust connection pipe 72 is fixedly arranged in the middle of the sound-absorbing plate 71, and one end of the exhaust connection pipe 72 extends to the outside of the top cover 7. The exhaust connection pipe 72 is provided to discharge the high-pressure gas generated during the operation of the device.

[0028] To connect the exhaust connection pipe 72 with the exhaust pipe 54, the present application further includes a pressing collar 73 formed by a downward depression in the middle of the sound-absorbing plate 71, and the pressing collar 73 communicates with the other end of the exhaust connection pipe 72. The upper end of the exhaust pipe 54 sequentially passes through the partition plate 51 and the connection disk 4, and is inserted into the cavity of the pressing collar 73. A sealing layer is provided at the joint where the upper end surface of the exhaust pipe 54 fits against the inner wall of the pressing collar 73. When the top cover 7 is installed on the upper opening of the housing 1 from top to bottom and the two are fixedly connected by tightening the bolts, the pressing collar 73 can just smoothly sleeve on the upper end of the exhaust pipe 54 and press the upper end surface of the exhaust pipe 54, so that the exhaust pipe 54 and the exhaust connection pipe 72 remain connected and prevent high-pressure gas leakage.

[0029] To facilitate the device to suck air from the outside, the present application further includes a mounting ring 15 fixedly arranged on the inner wall of the middle part of the housing 1. The drive shaft 6 movably passes through the middle of the mounting ring 15, and a sealing layer is provided at the joint where the two fit. An air inlet 14 is opened on the upper part of the inner side wall of the housing 1, and an air suction port 32 is penetrated through the side wall of the static disk seat 3. As Figure 1 shown, external air can enter the inner cavity of the housing 1 through the air inlet 14, and then enter the inner cavity of the static disk seat 3 through the air suction port 32 for the dynamic scroll disk 21 and the static scroll disk 31 to cooperate with each other for gas compression. In addition, to ensure that the air inhaled by the device is cleaner, a filtering structure known in the prior art can be provided on the air flow path between the air inlet 14 and the air suction port 32, which will not be elaborated here.

[0030] For the convenience of installing and disassembling the static disk seat 3, the present application further has a plurality of inner convex blocks 11 fixed to the upper end of the inner side wall of the housing 1 and distributed in an annular array. An outer convex block 33 corresponding to each of the plurality of inner convex blocks 11 is fixed to the upper end of the side wall of the static disk seat 3, and the outer convex block 33 and the inner convex block 11 are fixedly connected by bolts. The cooperation between the outer convex block 33 and the inner convex block 11 can be used for installing and positioning the static disk seat 3, and the two can be separated from each other by relative rotation. In addition, a plurality of tension bolts 53 are provided and spirally distributed along the length direction of the scroll groove 55, and the distances between every two of the plurality of tension bolts 53 increase sequentially from the middle of the pressing disk 5 to the edge. Since the air pressure at the center between the moving scroll disk 21 and the static scroll disk 31 is the largest and the air pressure at the edge is smaller, by specifically distributing the plurality of tension bolts 53, the sealing performance of the present device can be further improved.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
