Description

Technical Field

[0002] With the increasing adoption of automotive applications, automotive scroll compressor technology has also undergone continuous iteration and updates, achieving rapid development to meet demands for lightweight design, high reliability, low NVH (noise, vibration, and harshness), high energy efficiency, and low cost. With the development of pure electric vehicles, the requirements for compressor NVH are even higher, necessitating continuous optimization of NVH during compressor development to ensure that the compressor's NVH meets the requirements of the entire vehicle.

[0003] In existing technologies, balancing weights are typically installed on the compressor rotor to balance its mass distribution, thereby reducing NVH (noise, vibration, and harshness). However, this requires repeated replacement of the balancing weights and testing to achieve a uniform mass distribution. Furthermore, replacing the balancing weights necessitates frequent disassembly and reassembly of compressor components such as the moving and stationary scrolls and the main frame, which increases time costs and is detrimental to NVH reduction.

[0027] With the development of automotive applications, automotive scroll compressor technology has also been continuously iterating and updating, achieving rapid development to meet demands for lightweight design, high reliability, low NVH (noise, vibration, and harshness), high energy efficiency, and low cost. With the development of pure electric vehicles, the requirements for compressor NVH are even higher, necessitating continuous optimization of NVH during compressor development to ensure it meets vehicle requirements. Current technology typically reduces NVH by installing balance weights on the compressor rotor to balance its mass distribution. However, this requires repeated replacement of the balance weights and testing to achieve a uniform mass distribution. Furthermore, replacing the balance weights necessitates frequent disassembly and reassembly of the compressor's moving and stationary scrolls and main frame, increasing time costs and hindering NVH reduction.

[0028] To address the related technical problems, this application provides a vehicle that includes the compressor described below.

[0029] To address the related technical problems, this application also provides a compressor, for details please refer to [link / reference needed]. Figures 1 to 3 , Figure 1 This is a schematic diagram of an embodiment of the compressor provided in this application. Figure 2 yes Figure 1 The diagram shows a structural schematic of one embodiment of the first and second balance blocks. Figure 3 yes Figure 2The diagram shows a disassembled structure of one embodiment of the first and second balance blocks.

[0030] The compressor includes a rotating assembly 100, a first counterweight 200, a first counterweight 300, and a first fixing member 400. The rotating assembly 100 includes a rotating shaft 110. The first counterweight 200 is connected to the outside of the rotating shaft 110, and a first mounting hole 211 is provided on the side of the first counterweight 200 away from the rotating shaft 110. The first counterweight 300 is provided with a first through hole 311 that passes through both opposite sides of the first counterweight 300 in the radial direction of the rotating shaft 110. The first counterweight 300 is located on the side of the first counterweight 200 away from the rotating shaft 110, and the first through hole 311 is correspondingly provided with the first mounting hole 211. The first fixing member 400 passes through the first through hole 311 and is fixedly connected in the first mounting hole 211, so that the first counterweight 300 and the first counterweight 200 are detachably connected in the radial direction.

[0031] The rotating assembly 100 may include a rotating shaft 110, a rotor 120, and a compression assembly. The rotor 120 can be considered as a hollow cylindrical structure. The rotating shaft 110 passes through the rotor 120 and is fixedly connected to the inner side of the rotor 120, thereby causing the rotor 120 to drive the rotating shaft 110 to rotate. The rotating shaft 110 may include a main shaft and an eccentric shaft. The main shaft passes through the rotor 120, and the eccentric shaft is connected to one end face of the main shaft. The compression assembly is spaced apart from the rotor 120 in the axial direction of the rotating shaft 110 and is connected to the eccentric shaft, thereby causing the eccentric shaft to drive the compression assembly to rotate eccentrically, achieving the purpose of compressing the refrigerant.

[0032] The first balance block 200 is connected to the outside of the rotating shaft 110. Exemplarily, the first balance block 200 may include a through hole through which the main shaft passes, thereby causing the first balance block 200 to be interference-fitted with the main shaft; alternatively, the first balance block 200 and the main shaft may be detachably connected by other components for fixing. Of course, in some other embodiments, the first balance block 200 may also be fixed to one side of the rotor 120 in the axial direction.

[0033] The first counterweight 300 is connected to the side of the first balance block 200 opposite to the rotation shaft 110 in the radial direction. The side of the first balance block 200 opposite to the rotation shaft 110 may have a first mounting hole 211, and the inner wall of the first mounting hole 211 may have an internal thread. The first counterweight 300 has a first through hole 311, which extends radially and penetrates both opposite sides of the first counterweight 300 in the radial direction. Furthermore, the first through hole 311 and the first mounting hole 211 correspond to each other in the radial direction. One end of the first fixing member 400 may have an external thread. The threaded end of the first fixing member 400 can pass through the first through hole 311 and connect with the internal thread of the first mounting hole 211 through the external thread to fix it within the first mounting hole 211. For example, the first through hole 311 may also be provided with an internal thread, so that the first counterweight 300 is connected to the first fixing member 400 through the internal thread of the first through hole 311, so that the first counterweight 300 and the first balance block 200 are detachably connected through the first fixing member 400; or the first fixing member 400 may include a column and a column head, the column is connected to one end of the column head, the radial dimension of the column head is larger than the radial dimension of the column and the first through hole 311, the end of the column head near the column abuts against the side of the first counterweight 300 away from the first balance block 200, the column head passes through the first through hole 311 and is screwed to the first mounting hole 211 through its own external thread, so that the first counterweight 300 is detachably connected to the first balance block 200 in the radial direction.

[0034] In this embodiment, the first counterweight 200 is disposed between the rotor 120 and the compression assembly, resulting in a smaller space for mounting the first counterweight 200 between the rotor 120 and the compression assembly. Furthermore, typically, a main frame is also provided between the compression assembly and the rotor 120 to separate the rotor 120 and the compression assembly. The first counterweight 200 is located between the main frame and the rotor 120, further reducing the installation space for the first counterweight 200. If the first counterweight 300 is connected to the first counterweight 200 in the axial direction of the rotating shaft 110 via the first fixing member 400, it would make replacing and disassembling the first counterweight 300 difficult, requiring the compression assembly and the main frame to be disassembled before replacing the first counterweight 300. Frequent disassembly and assembly of other components could introduce other factors affecting NVH (Noise, Vibration, and Harshness). Therefore, the first counterweight 300 is detachably connected to the first counterweight 200 in the radial direction via the first fixing member 400, which facilitates the disassembly of the first counterweight 300.

[0035] Through the above implementation method, the first counterweight 300 can be detachably connected to the first balance block 200 in the radial direction, so that the first counterweight 300 can be replaced without disassembling other components, thereby adjusting the mass distribution, improving NVH optimization efficiency, saving optimization costs, and without adding other factors that affect NVH, thus improving the NVH optimization effect.

[0036] In some embodiments, the compressor includes a second balance block 510, a second counterweight (not shown), and a third fixing member (not shown). The rotating assembly 100 includes a rotor 120, a rotating shaft 110 passing through the rotor, the rotor 120 being located on one side of the first balance block 200, the second balance block 510 being located on the side opposite to the first balance block 200, and the second counterweight being detachably connected to the second balance block 510 via the third fixing member.

[0037] As an example, the compressor includes a second balance block 510 and a third fixing member. The second balance block 510 is detachably connected in the axial direction to the side of the rotor 120 opposite to the first balance block 200 via the third fixing member. As another example, the compressor may include a second balance block 510, a second counterweight (not shown), and a third fixing member. The second balance block 510 may be fixed to the side of the rotor 120 opposite to the first balance block 200, or it may be sleeved on the outer periphery of the rotating shaft 110. The second counterweight may be detachably connected to the second balance block 510 in the radial direction via the third fixing member; or it may be detachably connected to the second balance block 510 in the axial direction via the third fixing member. Because the side of the rotor 120 opposite to the first balance block 200 typically only has one bearing, providing ample space on that side, the second counterweight can be connected to the second balance block 510 in both the axial and radial directions. Therefore, the first balance block 200 and the second balance block 510 are located on both sides of the rotor 120, which is conducive to uniform mass distribution and reduced NVH. Furthermore, the second balance block 510 and the rotor 120, as well as the second balance block 510 and the second counterweight, can be detachably connected, thereby further improving the efficiency of NVH optimization.

[0038] In some embodiments, the line connecting the center of mass of the first balance block 200 and the first counterweight 300 as a whole with the center of mass of the second balance block 510 and the second counterweight as a whole passes through the axis of the rotation shaft 110 and is located on both sides of the axis of the rotation shaft 110 in the radial direction.

[0039] As a result, the center of mass of the first balance block 200 and the first counterweight block 300 as a whole is located in the radial direction and on opposite sides of the axis of the rotation shaft 110, thereby achieving uniform mass distribution and reducing NVH.

[0040] In this embodiment, the center of mass of the first balance block 200, the center of mass of the first counterweight block 300, the center of mass of the second balance block 510, and the center of mass of the second counterweight block can all be in the radial direction. The center of mass of the first balance block 200, the center of mass of the first counterweight block 300, the center of mass of the second balance block 510, and the center of mass of the second counterweight block are respectively on both sides of the axis of the rotating shaft 110. This simplifies the operation process when setting a uniform mass distribution when replacing the first counterweight block 300 and the second counterweight block with different masses, thereby improving the efficiency of NVH optimization.

[0041] Furthermore, after each first counterweight 300 of different weights is installed on the compressor, the orthographic projections of each first counterweight 300 of different weights on the rotor 120 can completely overlap, differing only in thickness. Similarly, the orthographic projections of second counterweights of different weights on the rotor 120 can also completely overlap, although their thicknesses differ. This ensures that when replacing first and second counterweights of different weights, the line connecting the centers of mass of the first and second counterweights of different weights always lies in the radial direction. This further improves the efficiency of NVH optimization.

[0042] In some embodiments, the first counterweight 300 includes a connecting portion 310 and a counterweight portion 320. A first through hole 311 is provided in the connecting portion 310. The connecting portion 310 is connected to the side of the first balance block 200 away from the rotating shaft 110 by a first fixing member 400. The counterweight portion 320 is connected to one side of the connecting portion 310 in the axial direction of the rotating shaft 110.

[0043] The connecting part 310 is connected to the side of the first balance block 200 opposite to the rotating shaft 110, and the connecting part 310 has a first through hole 311 penetrating through its two opposite sides in the radial direction. The counterweight part 320 can be connected to the side of the connecting part 310 near the rotor 120 or to the side opposite to the rotor 120 in the axial direction. Therefore, by connecting the counterweight part 320 to one side of the connecting part 310 in the axial direction, the radial dimensions of the first through hole 311 and the first fixing member 400 can be reduced, thereby improving the connection strength between the first balance block 200 and the first counterweight 300, and reducing the processing and assembly difficulty of the first counterweight 300.

[0044] In this embodiment, both the connecting part 310 and the counterweight part 320 can be arc-shaped, which makes it easier to evenly distribute the mass of the internal parts of the compressor during rotation, and can effectively reduce NVH.

[0045] In some embodiments, the first balancing block 200 includes a balancing body 210 and a plurality of positioning pins 212. The connecting part 310 is provided with a plurality of positioning holes 321 corresponding to the plurality of positioning pins 212. The plurality of positioning pins 212 are spaced apart in the circumferential direction of the rotating shaft 110. The plurality of positioning pins 212 are connected to the side of the balancing body 210 away from the rotating shaft 110. The first mounting hole 211 is provided on the side of the balancing body 210 away from the rotating shaft 110.

[0046] For example, the first balance block 200 may include two locating pins 212, which are spaced apart in the circumferential direction. The two locating pins 212 can be connected to the side of the first balance block 200 opposite to the rotation shaft 110. Further, the side of the first balance block 200 opposite to the rotation shaft 110 has two mounting pin holes, and one locating pin 212 is inserted into one mounting pin hole. The connection can be fixed by welding or by interference fit. The connecting part 310 has two locating holes 321, which are also spaced apart in the circumferential direction. The connecting part 310 is connected to the side of the first balance block 200 opposite to the rotation shaft 110, and each locating pin 212 is inserted into one locating hole 321. Therefore, after the multiple positioning pins 212 of the first balance block 200 and the multiple positioning holes 321 of the connecting part 310 are positioned, the first mounting hole 211 and the first through hole 311 can be accurately aligned, reducing the installation difficulty. Furthermore, the shear force from the first balance block 200 in the circumferential direction can be shared by the first fixing member 400, reducing the risk of deformation of the first fixing member 400. Of course, in some other embodiments, the number of positioning pins 212 and positioning holes 321 can be greater, such as three or four.

[0047] In some embodiments, the axial and radial directions of the rotating shaft 110 constitute a virtual reference plane 570, the first balance block 200 and the first counterweight block 300 are symmetrically arranged with respect to the virtual reference plane 570, and there are multiple first fixing members 400, with multiple first fixing members 400 and multiple positioning pins 212 symmetrically arranged with respect to the virtual reference plane 570.

[0048] The radial and axial directions of the rotating shaft 110 constitute a virtual reference plane 570. In this embodiment, the number of first fixing members 400 can also be multiple, thereby improving the connection strength between the first balance block 200 and the first counterweight block 300 to meet the working intensity of the first counterweight block 300 and the first balance block 200 rotating at high speed. For example, the number of first fixing members 400 can be two, and the two first fixing members 400 can be located on both sides of the multiple positioning pins 212 in the circumferential direction, thereby improving the stability of the connection between the first balance block 200 and the first counterweight block 300. The first balance block 200 and the first counterweight block 300 can be symmetrically arranged with respect to the virtual reference plane 570, that is, with respect to the virtual reference plane 570, the masses of the first balance block 200 and the first counterweight block 300 located on both sides of the virtual reference plane 570 are equal, thereby facilitating NVH optimization. Furthermore, the multiple locating pins 212 are symmetrically arranged relative to the virtual reference plane 570, and the multiple first fixing members 400 can also be symmetrically arranged relative to the virtual reference plane 570, thereby symmetrically distributing the multiple first fixing members 400 and the multiple locating pins 212 on the first counterweight block 300 and the first balance block 200. Thus, the symmetrical arrangement of the first balance block 200, the first counterweight block 300, and the multiple first fixing members 400 and the multiple locating pins 212 relative to the virtual reference plane 570 ensures that the relevant components can effectively balance the mass distribution, improving the NVH optimization effect of the compressor.

[0049] In addition, the second balance block 510, the second counterweight block and the third fixing component can also be symmetrically arranged relative to the virtual reference plane 570, thereby improving the NVH optimization effect of the compressor.

[0050] See Figure 4 and Figure 5 , Figure 4 yes Figure 1 A schematic diagram of another embodiment of the first counterweight shown. Figure 5 yes Figure 1 The diagram shows a structural schematic of a first embodiment of the first balancing block.

[0051] In some embodiments, one of the first balance block 200 and the first counterweight block 300 is provided with a locking part 322 and the other is provided with a locking groove 323. The locking groove 323 and the locking part 322 extend along the circumferential direction of the rotation shaft 110 and are locked together.

[0052] For example, the first counterweight 200 is provided with a locking portion 322, which can be understood as a protrusion provided on the first counterweight 200. The locking portion 322 can be provided on the side of the first counterweight 200 that connects to the first counterweight 300 in the radial direction; or, the locking portion 322 can be provided on the side of the first counterweight 200 in the axial direction. The locking portion 322 can be a wedge-shaped structure. The first counterweight 300 is provided with a locking groove 323, which can be provided on the side of the first counterweight 300 that connects to the first counterweight 200. The locking groove 323 can be a through hole. The locking groove 323 and the locking portion 322 can extend in the circumferential direction and engage with each other. Therefore, the snap-fit ​​portion 322 and the snap-fit ​​groove 323 extend in the circumferential direction and snap together, thereby limiting the relative displacement of the first balance block 200 and the first counterweight block 300 in the radial direction, and sharing the centrifugal force in the radial direction with the first fixing member 400, improving the connection stability between the first balance block 200 and the first counterweight block 300, thereby improving the NVH optimization effect of the compressor. Of course, in some other embodiments, the snap-fit ​​groove 323 may also be provided in the first balance block 200, and the snap-fit ​​portion 322 may also be provided in the first counterweight block 300.

[0053] Furthermore, there can be multiple snap-fit ​​parts 322 and snap-fit ​​slots 323, with multiple snap-fit ​​parts 322 and snap-fit ​​slots 323 spaced apart in the circumferential direction, and each snap-fit ​​part 322 snapping into one snap-fit ​​slot 323. This serves both a positioning function and avoids the first fixing member 400, while also improving the connection stability between the first balance block 200 and the first counterweight block 300 without reducing their structural strength.

[0054] See Figure 6 , Figure 6 yes Figure 1 A schematic diagram of the second embodiment of the first balance block is shown.

[0055] In some embodiments, the first balance block 200 has a connection port 213, a mounting notch 214, a second through hole 215, and a second fixing member 216. The inner side of the connection port 213 is connected to the outer side of the rotating shaft 110. The mounting notch 214 penetrates one side of the first balance block 200 in the radial direction and communicates with the connection port 213. The radial dimension of the mounting notch 214 is equal to or greater than the radial dimension of the rotating shaft 110. The second through hole 215 penetrates the inner and outer sides of the first balance block 200 in the radial direction. The second through hole 215 is spaced apart from the first counterweight 300 in the circumferential direction of the rotating shaft 110. The second fixing member 216 passes through the second through hole 215 and is screwed to the rotating shaft 110.

[0056] The connecting port 213 is a through hole penetrating the two opposite sides of the first counterweight 200 in the axial direction, for connection with the rotating shaft 110. The mounting notch 214 is a through hole penetrating the first counterweight 200 in the radial direction, with one end of the mounting notch 214 facing away from the first counterweight 300 in the radial direction. The mounting notch 214 communicates with the connecting port 213, and the radial dimension of the mounting notch 214 is equal to or greater than the radial dimension of the rotating shaft 110, so that the first counterweight 200 avoids the rotating shaft 110 through the mounting notch 214, thereby connecting the connecting port 213 with the rotating shaft 110. The second through hole 215 is spaced apart from the first counterweight 300 in the axial direction, and the second through hole 215 penetrates the inner and outer sides of the first counterweight 200 in the radial direction, communicating with the connecting port 213. The rotating shaft 110 may have a threaded hole, and the second fixing member 216 passes through the second through hole 215, thereby being screwed into the threaded hole of the rotating shaft 110. Therefore, the first balance block 200 can also be detachably connected to the rotating shaft 110 in the radial direction, so that the first balance block 200 can be replaced without disassembling other parts, without introducing other factors that affect NVH, thereby improving the optimization efficiency and effect of NVH optimization.

[0057] In some embodiments, the compressor includes at least one mounting base 550 and a plurality of fourth fasteners 560. One mounting base 550 is located at one end of the rotor 120 away from the first balance block 200, and the second balance block 510 is located on the side of the mounting base 550 away from the rotor 120. The plurality of fourth fasteners 560 are spaced apart in the circumferential direction of the rotating shaft 110. Each fourth fastener 560 passes through the mounting base 550 to be fixed to the rotor 120, and some of the fourth fasteners 560 pass through the second balance block 510 to be fixed to the mounting base 550.

[0058] For example, there may be two mounting bases 550, located on opposite sides of the rotor 120 in the axial direction. Multiple fourth fasteners 560 are spaced apart in the circumferential direction, each passing through both mounting bases 550 and the rotor 120, thereby fixing the mounting bases 550 to both sides of the rotor 120. A second balance block 510 is located on the side of a mounting base 550 away from the rotor 120, away from the first balance block 200. Some of the fourth fasteners 560 also pass through the second balance block 510, thus fixing the second balance block 510 to this mounting base 550. Therefore, mounting the second balance block 510 on the side of a mounting base 550 away from the rotor 120 provides a good mounting surface for the second balance block 510, allowing for more stable fixation and promoting a more uniform mass distribution, thus improving the NVH optimization effect on the compressor.

[0059] In summary, the first counterweight 300 can be detachably connected to the first balance block 200 in the radial direction, which means that the first counterweight 300 can be replaced without disassembling other components, thereby adjusting the mass distribution, improving NVH optimization efficiency, saving optimization costs, and without adding other factors that affect NVH, thus improving the NVH optimization effect.
