Description

[0001] Cross-reference to related applications

[0002] This application claims priority to Korean Patent Application No. 10-2024-0133242, filed on September 30, 2024, and Korean Patent Application No. 10-2025-0043578, filed on April 3, 2025, the entire contents of which are incorporated herein by reference for all purposes. Technical Field

[0003] The present invention relates to compressor assemblies, and more particularly to compressor assemblies in which an integral cover can be produced in a single mold, and the integral cover is then folded by multiple fold lines to cover the compressor, thereby improving the assemblability and productivity of the cover, and grounding wires can be assembled and guided to the outside of the cover using trimmed portions of the cover without forming separate holes in the cover. Background Technology

[0004] Typically, air conditioning (A / C) units used for cooling and heating the interior are installed in vehicles. The cooling system of such A / C units has a compressor that compresses the low-temperature, low-pressure gaseous refrigerant drawn from the evaporator into a high-temperature, high-pressure gaseous refrigerant and delivers the compressed gaseous refrigerant to the condenser.

[0005] In this case, to prevent noise generated by the compressor from being transmitted to the outside of the compressor, NVH (noise, vibration, and harshness) coverings can be provided around the compressor, such as... Figure 1 The conventional compressor assembly shown.

[0006] Specifically, such as Figure 1 As shown, a conventional compressor assembly may include a compressor 10, a sound-absorbing cover 20 surrounding the compressor 10, and a sound-insulating cover 30 surrounding the compressor 10 outside the sound-absorbing cover 20.

[0007] In this case, each of the sound-absorbing cover 20 and the sound-insulating cover 30 consists of two parts separated in the left-right or vertical direction, and has a structure in which the two parts are assembled on the two sides of the compressor 10.

[0008] Therefore, since at least two molds are required to manufacture the sound-absorbing cover 20 and the sound-insulating cover 30, and a considerable number of fastening components are needed to assemble the two parts, there are problems with the poor productivity and assemblability of the covers.

[0009] In addition, in order to establish a stable electrical ground between the compressor 10 and the vehicle body, the compressor 10 and the vehicle body need to be connected to a grounding wire, and therefore there is a problem that holes for guiding the grounding wire from the compressor 10 to the outside of the covers 20 and 30 need to be formed separately in the covers 20 and 30.

[0010] Furthermore, there is a problem that when the covers 20 and 30 surround the compressor 10, which is formed by injection molding from a casting such as aluminum, noise is amplified in a specific frequency (Hz) band when the covers 20 and 30 vibrate additionally due to the gap between the compressor 10 and the covers 20 and 30. Summary of the Invention

[0011] The present invention aims to provide a compressor assembly in which an integral cover can be produced in a single mold, and then the integral cover is folded by multiple fold lines to cover the compressor, thereby improving the assemblability and productivity of the cover, and the grounding wire can be assembled and guided to the outside of the cover using the trimmed portion of the cover without forming a separate hole in the cover.

[0043] For clarity in describing the invention, irrelevant details have been omitted, and identical or similar components are indicated by the same reference numerals throughout the specification. Throughout the specification, when a part is described as "including" a component, it means that another component is further included rather than excluded, unless otherwise specifically stated.

[0044] Additionally, a component described as a "unit" throughout the specification can be two or more components combined into one component, or a component can be divided into two or more components based on more detailed functions. Furthermore, it is evident that, in addition to the main functions each component is responsible for, each component described below can additionally perform some or all of the functions of the other components, and some of the main functions of the main functions of each component can be performed by other components.

[0045] In the following text, reference will be made to Figures 2 to 6 A compressor assembly according to one embodiment of the present invention is described.

[0046] The compressor assembly of the present invention includes a compressor 100 and a cover 200, the cover 200 surrounding the compressor 100 to prevent noise generated by the compressor 100 from being transmitted to the outside of the compressor 100.

[0047] Compressor 100 may include housing 120, motor unit, compression unit, and inverter unit, such as Figure 4 It is shown schematically in the diagram.

[0048] The housing 120 forms the overall appearance of the compressor 100, and in this embodiment, the housing 120 is composed of a motor housing 122, a compressor housing 124 connected to one side of the motor housing 122, and an inverter housing 126 connected to the other side of the motor housing 122.

[0049] The motor unit is disposed within the motor housing 122 and provides power to the compression unit to compress the refrigerant. Although not shown, the motor unit may include: a rotor coupled to a rotating shaft rotatably mounted at the center of the motor housing 122; and a stator fixed to the motor housing 122 and disposed radially outside the rotor. Additionally, the stator may include a stator core and coils wound around the stator core.

[0050] The compression unit is driven by a motor unit to compress the refrigerant flowing into the housing 120. In this embodiment, the compression unit may be disposed in a compression housing 124, and although not shown, the compression unit may include a moving scroll member connected to a rotating shaft via an eccentric bushing and a stationary scroll member forming a compression chamber together with the moving scroll member, in which the refrigerant is compressed. In this way, since the compression unit is connected to the motor unit via a rotating shaft, the rotational force generated from the motor unit can be transmitted to the moving scroll member of the compression unit via the rotating shaft. However, the invention is not limited thereto, and it is apparent that another type of compression unit may also be used.

[0051] The inverter unit is housed within the inverter housing 126 and is positioned on the opposite side of the compression unit from the motor unit. The inverter unit is electrically connected to the motor unit and supplies power to it, controlling its operation via power and control signals transmitted from an external source. Specifically, the stator generates an electromagnetic field using the power supplied from the inverter unit, and as the rotor rotates through this electromagnetic field, it generates a rotational force to drive the compression unit.

[0052] However, Figure 4 The structure and shape of the compressor 100 shown are an example, and various structures and shapes of the compressor 100 can be applied to the present invention.

[0053] In this invention, the cover 200 is formed as a single body and folded along multiple fold lines to cover the compressor 100. That is, the cover 200 corresponds to a seamless component, and all parts covering the compressor 100 are folded along multiple fold lines when joined. Therefore, the cover 200 can be produced in a single mold.

[0054] In this way, since the one-piece cover 200 is produced in a single mold and then folded by multiple folding lines to cover the compressor 100, the assemblability and productivity of the cover 200 can be improved.

[0055] Figure 5 This is an exploded view showing the state of the one-piece cover 200 before it is assembled after being manufactured from a single mold.

[0056] like Figure 5As shown, in this embodiment, the cover 200 includes four cover portions that can be folded relative to each other via three fold lines. Specifically, the cover 200 includes: a first cover portion 210, which is configured to face the front surface of the inverter housing of the compressor 100; a second cover portion 220, which is configured to face one side surface of the compressor 100 and is foldable relative to the first cover portion 210 via the first fold line 201; a third cover portion 230, which is configured to face another side surface of the compressor 100 and is foldable relative to the first cover portion 210 via the second fold line 202; and a fourth cover portion 240, which is configured to face the upper surface of the inverter housing of the compressor 100 and is foldable relative to the third cover portion 230 via the third fold line 203.

[0057] The first cover portion 210 is positioned facing the front surface of the inverter housing 126 and is located in the central portion of the cover 200 in an exploded view.

[0058] The second cover portion 220 is configured to cover one side surface of the compressor 100, namely, one side surface of all of the inverter housing 126, the motor housing 122, and the compressor housing 124, and the second cover portion 220 is connected to one side of the first cover portion 210. Since the first fold line 201 is provided between the first cover portion 210 and the second cover portion 220, the first cover portion 210 and the second cover portion 220 can be folded together along the first fold line 201 in a direction toward each other.

[0059] The third cover portion 230 is configured to cover the other side surface of the compressor 100, namely all the other side surfaces of the inverter housing 126, the motor housing 122, and the compressor housing 124, and the third cover portion 230 is connected to the other side of the first cover portion 210. Since the second fold line 202 is provided between the first cover portion 210 and the third cover portion 230, the first cover portion 210 and the third cover portion 230 can be folded towards each other via the second fold line 202.

[0060] The fourth cover portion 240 is positioned facing the upper surface of the inverter housing 126 and is connected to the third cover portion 230. Since the third fold line 203 is provided between the third cover portion 230 and the fourth cover portion 240, the third cover portion 230 and the fourth cover portion 240 can be folded together in a direction toward each other via the third fold line 203.

[0061] Figure 6This is an exploded view showing the assembled state of the cover 200. In this case, the assembled state of the cover 200 is secured by fastening members.

[0062] Specifically, one or more first fastening members 300 fasten the second cover portion 220 and the third cover portion 230, and one or more second fastening members 400 fasten the second cover portion 220 and the fourth cover portion 240. In this embodiment, four first fastening members 300 and one second fastening member 400 may be provided, but this embodiment is not limited to this, and the number of first fastening members and second fastening members may be changed in various ways.

[0063] For this purpose, first fastening holes 221 and 231 for the first fastening members 300 to pass through are respectively provided along the periphery of the second cover portion 220 and the periphery of the third cover portion 230. Specifically, the four first fastening holes 221 for the four first fastening members 300 to pass through are spaced apart from each other along the periphery of the second cover portion 220, and the four first fastening holes 231 for the four first fastening members 300 to pass through are also spaced apart from each other along the periphery of the third cover portion 230.

[0064] In some cases, the second cover portion 220 may have a lug portion configured to protrude from the periphery to form a first fastening hole 221 in the second cover portion 220, and the third cover portion 230 may have a lug portion configured to protrude from the periphery to form a first fastening hole 231 in the third cover portion 230.

[0065] When the second cover portion 220 and the third cover portion 230 are folded and assembled relative to the first cover portion 210 to cover one side surface and the other side surface of the compressor 100, respectively, the first fastening hole 221 of the second cover portion 220 corresponds one-to-one with the first fastening hole 231 of the third cover portion 230. Therefore, the first fastening member 300 can pass through the first fastening hole 221 of the second cover portion 220 and the first fastening hole 231 of the third cover portion 230 simultaneously to secure the second cover portion 220 and the third cover portion 230.

[0066] In addition, second fastening holes 222 and 242 for the second fastening member 400 to pass through are respectively provided along the periphery of the second cover portion 220 and the periphery of the fourth cover portion 240. Specifically, a second fastening hole 222 for a second fastening member 400 to pass through is provided along the periphery of the second cover portion 220, and a second fastening hole 242 for a second fastening member 400 to pass through is also provided along the periphery of the fourth cover portion 240.

[0067] Similarly, the second cover portion 220 may have a lug portion configured to project from its periphery to form a second fastening hole 222 in the second cover portion 220, and the fourth cover portion 240 may have a lug portion configured to project from its periphery to form a second fastening hole 242 in the fourth cover portion 240. In this embodiment, the second fastening hole 242 of the fourth cover portion 240 may be formed in a lug portion 244 configured to project from the periphery of the fourth cover portion 240, and the lug portion 244 may be folded relative to the fourth cover portion 240 by a fourth fold line 204.

[0068] When each of the second cover portion 220 and the third cover portion 230 is folded relative to the first cover portion 210 and the fourth cover portion 240 is also folded relative to the third cover portion 230 and assembled, the fourth cover portion 240 is adjacent to both the first cover portion 210 and the second cover portion 220. In this case, when the lug portion 244 is folded relative to the fourth cover portion 240 to overlap with the second cover portion 220, the second fastening hole 222 of the second cover portion 220 overlaps with the second fastening hole 242 of the fourth cover portion 240. Therefore, the second fastening member 400 can pass through both the second fastening hole 222 of the second cover portion 220 and the second fastening hole 242 of the fourth cover portion 240 simultaneously to secure the second cover portion 220 and the fourth cover portion 240.

[0069] Therefore, the cover 200 can be secured in an assembled state by the first fastening member 300 and the second fastening member 400. Specifically, the first fastening member 300 and the second fastening member 400 can be assembled along one direction of the compressor 100, more specifically, along the direction of the second cover portion 220 on which the compressor 100's suction port 130 and discharge port 140 are disposed. Therefore, the operator can easily assemble the compressor assembly without changing its orientation during the assembly process.

[0070] When the fourth cover portion 240 is connected to the second cover portion 220 instead of the third cover portion 230, the second fastening member 400 needs to fasten both the third cover portion 230 and the fourth cover portion 240. Therefore, unlike the first fastening member 300, the second fastening member 400 needs to be assembled along the direction of the third cover portion 230. Thus, after the first fastening member 300 is fastened along the direction of the second cover portion 220, the orientation of the compressor assembly needs to be changed to fasten the second fastening member 400 along the direction of the third cover portion 230, resulting in a bulky and time-consuming process.

[0071] In this invention, the cover 200 is composed of a sound-insulating material 200a and a sound-absorbing material 200b, the sound-absorbing material 200b being disposed on the sound-insulating material 200a and being a different material from the sound-insulating material 200a. For example, the sound-insulating material 200a may be a flexible and repeatedly foldable plastic fiber material (e.g., PET felt), and the sound-absorbing material 200b may be a polyurethane (PU) having a higher strength than the sound-insulating material 200a.

[0072] In this case, the sound-absorbing material 200b is preferably disposed in a location other than the multiple fold lines of the cover 200 and the periphery of the cover 200. For example... Figure 5 As shown, in this embodiment, the periphery of the first fold lines 201 to the fourth fold lines 204, the periphery of the first cover portion 210 to the fourth cover portion 240, and the periphery of the first fastening holes 221 and 231 and the second fastening holes 222 and 242 are all formed of sound-insulating material 200a, and in addition to the sound-insulating material 200a, only the internal portions of the first cover portion 210 to the fourth cover portion 240 have sound-absorbing material 200b. Therefore, the cover 200 can be easily and repeatedly folded along the fold lines, and the portions that do not need to be folded can absorb the noise generated from the compressor 100 through the sound-absorbing material 200b.

[0073] Furthermore, the multiple fold lines can be formed to be thinner than other parts of the cover 200. That is, the first fold line 201 to the fourth fold line 204 can be formed in the form of grooves. Therefore, the cover 200 can be folded well even with a small amount of force.

[0074] According to one embodiment, a fifth cover portion 250, used to cover the area between the high-pressure connector 150 and the low-pressure connector 160 of the compressor 100, can be additionally connected to a fourth cover portion 240. In this way, the area of ​​the compressor 100 exposed to the outside can be minimized, thereby effectively suppressing radiated noise.

[0075] On one side surface of the compressor 100, there is an intake port 130 for drawing refrigerant into the compressor 100, and a discharge port 140 for discharging compressed refrigerant to the outside of the compressor 100. Therefore, a port penetration portion 224 for the intake port 130 or the discharge port 140 to pass through can be formed on the second cover portion 220.

[0076] Additionally, the compressor 100 has a plurality of mounting lugs 170 for securing the compressor 100 to the vehicle body. Therefore, a plurality of mounting lug penetration portions 225 and 235 for the plurality of mounting lugs 170 to pass through can be formed on the second cover portion 220 and the third cover portion 230.

[0077] Additionally, the compressor 100 has a pressure relief valve (PRV) for releasing pressure by discharging refrigerant to the outside when the internal pressure of the compressor 100 is too high. Therefore, a valve port 226 for the PRV (not shown) to pass through or for fluid discharged from the PRV to pass through can be formed in the second cover portion 220.

[0078] As described above, the first fold line 201 and the second fold line 202 are formed on the two edges of the inverter housing 126 instead of on the central portion of the inverter housing 126. When the fold lines are formed on the central portion of the inverter housing 126, the sound-absorbing material 200b is not arranged around the fold lines, and therefore the sound-absorbing material 200b is not arranged in the inverter section that has the greatest impact on radiated noise, which is very detrimental to sound insulation performance.

[0079] Furthermore, in order to establish a stable electrical ground between the compressor 100 and the vehicle body, the compressor 100 and the vehicle body need to be connected via a grounding wire 500. When the folded wire is formed on the edge of the inverter housing 126, the trimmed portion provided on the folded portion can serve as a passage and assembly space for the grounding wire 500 of the compressor 100. Therefore, there is an advantage that a separate hole for the grounding wire 500 does not need to be formed in the cover 200.

[0080] The following text will describe in detail the assembly of the grounding wire 500 using the trimmed portion and the structure for guiding the grounding wire 500 from the compressor 100 to the outside of the cover 200.

[0081] The trimming section is specifically designed to ensure that the folded portion can be easily separated from the mold after the one-piece cover 200 is produced in a single mold. In other words, the trimming section is not processed separately after the cover 200 is manufactured, but is formed during the manufacturing process of the cover 200.

[0082] Trimming portions are formed between adjacent cover portions, wherein one of the multiple fold lines of the cover 200 is inserted between the cover portions. In the cover 200 of this embodiment, a first trimming portion 260 is formed between the first cover portion 210 and the third cover portion 230, and a second trimming portion 270 is formed between the first cover portion 210 and the second cover portion 220.

[0083] In this embodiment, since the first trimming portion 260 is used for assembling and guiding the grounding wire 500, the first trimming portion 260 is formed to be larger than the second trimming portion 270. Additionally, as... Figure 5As shown, the first trimming portion 260 is formed at a position higher than the second trimming portion 270 in the direction of gravity. However, this embodiment is not limited to this, and when the second trimming portion 270 is used to assemble and guide the grounding wire 500, the second trimming portion 270 may be formed to be larger than the first trimming portion 260.

[0084] like Figure 3 As shown, when the cover 200 is assembled, a first trimmed portion 260 is formed at a location on at least a portion of the front surface of the inverter housing 126 facing the compressor 100. Therefore, the grounding bolt 600 can be grounded by assembling the grounding wire 500 into the first trimmed portion 260 to the front surface of the inverter housing 126. In this way, stable grounding is possible by arranging the grounding bolt 600 on the inverter side of the input and output power.

[0085] Subsequently, the grounding wire 500, assembled and grounded by the grounding bolt 600, needs to pass through the first trimmed portion 260 to be guided to the outside of the cover 200 and connected to the vehicle body. In this case, the grounding wire 500 is preferably guided toward the side surface of the compressor 100, as it is specifically connected to the chassis grounding part of the vehicle.

[0086] For this purpose, when the cover 200 is assembled, the first trimmed portion 260 extends to at least a portion of the side surface of the inverter housing 126 facing the compressor 100. That is, the first trimmed portion 260 extends from the front surface of the inverter housing 126 to the side surface of the inverter housing 126.

[0087] Therefore, the grounding wire 500, assembled by the grounding bolt 600, can extend from the front surface of the inverter housing 126 to the side surface of the inverter housing 126 inside the cover 200, and then be guided to the outside of the cover 200 by a first trimmed portion 260 positioned on the side surface of the inverter housing 126. That is, the grounding wire 500 can extend from inside the cover 200 to the side surface of the compressor 100 and then be guided to the outside of the cover 200, instead of being guided from the front surface of the inverter housing 126 to the outside of the cover 200 and then extending to the side surface of the compressor 100. Therefore, the grounding wire 500 can be protected by the cover 200 as much as possible and can extend the shortest distance until it connects to the vehicle body outside the cover 200.

[0088] Specifically, in this embodiment, the first trimmed portion 260 extends in an L-shape from a position facing the side surface of the inverter housing 126 to a position facing the front surface of the inverter housing 126. Therefore, as... Figure 3As shown, the grounding wire 500 can be effectively guided to the outside of the cover 200 through a portion that extends narrowly upward from the first trimmed portion 260.

[0089] Additionally, the cover 200 may have a capturing portion 280 that protrudes to capture the grounding wire 500. In this embodiment, the capturing portion 280 is disposed on the periphery of the fourth cover portion 240 and is formed solely of the sound-insulating material 200a. The capturing portion 280 protrudes in an L-shape from the periphery of the fourth cover portion 240, allowing the grounding wire 500 to be temporarily secured to the recess.

[0090] Specifically, the capturing portion 280 can be formed to protrude from the portion of the fourth cover portion 240 adjacent to the first cover portion 210. Specifically, the capturing portion 280 is formed on the edge of the fourth cover portion 240 where the lug 244 is not formed and on the edge of the fifth cover portion 250, i.e., the edge facing the first cover portion 210. Therefore, when the fourth cover portion 240 is connected to the first cover portion 210 instead of the third cover portion 230, there is a disadvantage that the capturing portion 280 cannot be formed.

[0091] Therefore, when the compressor assembly is manufactured and moved while the compressor 100 and cover 200 are assembled and the grounding wire 500 is assembled to the compressor 100 via the grounding bolt 600, as... Figure 3 As shown, the grounding wire 500 can be stably fixed to the cover 200, thereby preventing damage to the grounding wire 500 during movement.

[0092] Next, we will refer to Figure 7 and Figures 8A to 8B A compressor assembly according to another embodiment of the present invention is described.

[0093] The compressor assembly of this embodiment also includes a compressor 100 and a cover 200 covering the compressor 100, and, since only the cover and Figures 2 to 6 The compressor assembly shown has a different cover, so cover 200 will be described primarily. More specifically, the difference is that the sound-absorbing material 200b of cover 200 includes a protrusion 700, and cover 200 also includes an assembly protrusion 820 and an assembly hole 840.

[0094] Even in this invention, the cover 200 is formed as a single body and is folded by multiple fold lines to cover the compressor 100. Figure 7 This is an exploded view showing the state of the one-piece cover 200 before it is assembled after being manufactured from a single mold.

[0095] like Figure 7As shown, the cover 200 includes four cover portions that can be folded relative to each other via three fold lines as described above. Specifically, the cover 200 includes: a first cover portion 210, which is configured to face the front surface of the inverter housing of the compressor 100; a second cover portion 220, which is configured to face one side surface of the compressor 100 and is foldable relative to the first cover portion 210 via the first fold line 201; a third cover portion 230, which is configured to face another side surface of the compressor 100 and is foldable relative to the first cover portion 210 via the second fold line 202; and a fourth cover portion 240, which is configured to face the upper surface of the inverter housing of the compressor 100 and is foldable relative to the third cover portion 230 via the third fold line 203.

[0096] Furthermore, the cover 200 is composed of sound-insulating material 200a and sound-absorbing material 200b, the sound-absorbing material 200b being disposed on the sound-insulating material 200a and being a different material from the sound-insulating material 200a. In this case, the sound-absorbing material 200b is disposed in locations other than the multiple fold lines of the cover 200 and the periphery of the cover 200.

[0097] In this embodiment, the sound-absorbing material 200b has at least one protrusion 700, such that at least one region of the cover 200 is thicker than other regions of the cover 200. The protrusion 700 is integrally formed with the sound-absorbing material 200b.

[0098] In this configuration, when the compressor 100 and the cover 200 are assembled, the protrusion 700 protrudes to contact and interfere with the compressor 100. That is, in at least one region of the cover 200, the sound-absorbing material 200b is compressed by the interference of the protrusion 700 with the compressor 100. Since the sound-absorbing material 200b is formed of polyurethane (PU) or a similar material that can be compressed and contracted, the protrusion 700 of the sound-absorbing material 200b is compressed by contacting and interfering with the compressor 100 during assembly. In this way, due to the compressive force of the sound-absorbing material 200b, the cover 200 and the compressor 100 are in close contact with each other to eliminate the occurrence of gaps between the cover 200 and the compressor 100, thereby reducing additional vibrations of the cover 200 when the compressor 100 is driven, and achieving stable and excellent noise reduction.

[0099] Figure 8A The image shows the protrusion 700 of the uncompressed sound-absorbing material 200b before the assembly of the compressor 100 and the cover 200, and... Figure 8BThe image shows a protrusion 700 of the sound-absorbing material 200b compressed after the compressor 100 and the cover 200 are assembled to bring the compressor 100 into close contact with the cover 200.

[0100] When the sound-absorbing material 200b is formed with a thickness having protrusions 700 in all areas, the cover 200 can be opened, and therefore the rigidity of the fastening members needs to be increased. Therefore, the protrusions 700 are preferably provided only in specific areas of the cover 200.

[0101] In this embodiment, the protrusions 700 are provided as a plurality of protrusions, and the plurality of protrusions 700 are provided on the second cover portion 220 and the third cover portion 230, and are specifically provided to face each other on the second cover portion 220 and the third cover portion 230. That is, the plurality of protrusions 700 provided on the second cover portion 220 are symmetrical to the plurality of protrusions 700 provided on the third cover portion 230.

[0102] Specifically, in this embodiment, the plurality of protrusions 700 include a first protrusion 700a, a second protrusion 700b, and a third protrusion 700c disposed on the second cover portion 220, and further include a fourth protrusion 700d, a fifth protrusion 700e, and a sixth protrusion 700f disposed on the third cover portion 230. In this case, during assembly, the first protrusion 700a and the fourth protrusion 700d are positioned facing each other, the second protrusion 700b and the fifth protrusion 700e are positioned facing each other, and the third protrusion 700c and the sixth protrusion 700f are positioned facing each other.

[0103] In the second cover portion 220, preferably, at least one of the plurality of protrusions 700 is provided on the region facing the inverter housing 126 and the region facing the compressor housing 124, respectively. In this embodiment, a first protrusion 700a is provided on the region facing the compressor housing 124, and a second protrusion 700b and a third protrusion 700c are provided on the region facing the inverter housing 126.

[0104] As described above, the periphery of the second cover portion 220 has a plurality of first fastening holes 221 and a single second fastening hole 222. A plurality of first fastening members 300 for fastening the second cover portion 220 and the third cover portion 230 pass through the plurality of first fastening holes 221, and a single second fastening member 400 for fastening the second cover portion 220 and the fourth cover portion 240 passes through the single second fastening hole 222.

[0105] In this configuration, in the second cover portion 220, a plurality of protrusions 700 are adjacent to or overlap, in the width direction, with either a virtual straight line A connecting the two first fastening holes 221 or a virtual straight line B connecting the first fastening holes 221 to the second fastening holes 222, the two first fastening holes 221 being positioned on opposite sides, wherein the sound-absorbing material 200b is inserted between the two first fastening holes 221. Therefore, when assembling the fastening members 300 and 400, a fastening force can be applied to the protrusions 700, allowing the protrusions 700 to be effectively compressed.

[0106] Specifically, in this embodiment, the first protrusion 700a overlaps with the virtual straight line A connecting the two first fastening holes 221 in the width direction, the two first fastening holes 221 being positioned on opposite sides, wherein the sound-absorbing material 200b is inserted between the two first fastening holes 221; the second protrusion 700b is adjacent to the virtual straight line B connecting the first fastening holes 221 and the second fastening holes 222, the first fastening holes 221 and the second fastening holes 222 being positioned on opposite sides, wherein the sound-absorbing material 200b is inserted between the first fastening holes 221 and the second fastening holes 222; and the third protrusion 700c overlaps with the same virtual straight line B in the width direction.

[0107] Furthermore, one of the assembly protrusion 820 and the assembly hole 840 may be provided on the periphery of the first cover portion 210, and the other of the assembly protrusion 820 and the assembly hole 840 may be provided on the periphery of the second cover portion 220 or the third cover portion 230. In this embodiment, two assembly protrusions 820 are provided on the periphery of the first cover portion 210, and each of the second cover portion 220 and the third cover portion 230 is provided with an assembly hole 840 into which the assembly protrusion 820 is inserted.

[0108] Therefore, since the cover portion is additionally secured by inserting the assembly protrusion 820 into the assembly hole 840 in addition to the fastening components, the noise reduction effect can be increased by increasing the adhesion strength between the cover 200 and the compressor 100.

[0109] According to the present invention, since the one-piece cover is produced in a single mold and then folded through multiple folding lines to cover the compressor, the assemblability and productivity of the cover can be improved. Ultimately, the assemblability and productivity of the compressor assembly are improved.

[0110] In particular, since the multiple fold lines can be formed to have a smaller thickness than other parts of the cover, and furthermore, the multiple fold lines can be formed from a plastic fiber material (e.g., PET felt) that can be repeatedly folded and can also be used as a sound insulation material, the cover can be easily assembled.

[0111] Furthermore, since the fastening components used to secure the cover can be assembled along one direction of the compressor after the exploded view of the cover is assembled, the operator can easily assemble the compressor assembly without changing the orientation of the compressor assembly during the assembly process.

[0112] In addition, since the grounding wire can be assembled and guided to the outside of the cover using the trimmed part of the cover, it is not necessary to form a separate hole in the cover.

[0113] Furthermore, because the sound-absorbing material is formed thicker in specific areas, the compressor can be firmly fixed by using the interference of the sound-absorbing material when assembling the cover. In other words, because the sound-absorbing material interferes with and is compressed by the compressor, the gap between the compressor and the cover can be suppressed, thereby reducing the additional vibration of the cover during compressor operation and achieving a stable and excellent noise reduction effect.

[0114] In addition to fastening components, the cover part is fixed by using assembly protrusions and assembly holes, thereby improving the adhesion strength of the cover part toward the compressor and increasing the noise reduction effect.

[0115] It should be understood that the effects of the present invention are not limited to those described above, but include all effects that can be inferred from the configuration of the invention as described in the detailed description or claims of the invention.

[0116] This invention is not limited to the specific embodiments and descriptions described above, and various modifications can be made by those skilled in the art without departing from the spirit of the invention as claimed in the claims, and such modifications are within the scope of this invention.
