[0031] The following is for reference. Figures 1-4 This invention describes a horizontal scroll compressor 100 for a vehicle according to an embodiment of the present invention.
[0032] Reference Figure 1 , Figure 2 and Figure 3 A horizontal scroll compressor 100 for vehicles according to an embodiment of the present invention includes: a housing 1, a drive assembly 2, and a compression assembly 3. The compression assembly 3 includes a moving scroll 31 and a stationary scroll 32. The stationary scroll 32 is disposed on the housing 1 and stationary relative to the housing 1. The moving scroll 31 meshes with the stationary scroll 32, forming a compression chamber 33 between the moving scroll 31 and the stationary scroll 32. The moving scroll 31 is rotatable relative to the stationary scroll 32 to compress the refrigerant within the compression chamber 33.
[0033] The drive assembly 2 is disposed inside the housing 1. The drive assembly 2 includes a rotatable crankshaft 21, which is connected to the moving scroll 31 for driving the moving scroll 31 to rotate relative to the stationary scroll 32.
[0034] An electrical control chamber is provided inside the housing 1, and an electrical control module is installed inside the electrical control chamber. The electrical control module is suitable for controlling the operating state of the scroll compressor 100. Specifically, the drive assembly 2 is communicatively connected to the electrical control module, so that the electrical control module can control the rotation state of the crankshaft 21, thereby controlling the operating state of the scroll compressor 100.
[0035] The housing 1 is also provided with a bracket 4. It should be noted that the bracket 4 can be completely disposed inside the housing 1, or it can be formed as part of the housing 1. For example, in some embodiments, the housing 1 includes a first housing 14 and a second housing 15 spaced apart, with the bracket 4 sandwiched between the first housing 14 and the second housing 15. In this embodiment, the bracket 4 is part of the housing 1. It should also be noted that in embodiments where the bracket 4 is completely disposed inside the housing 1, the bracket 4 can be an integrally formed part with the housing 1, or it can be a separate formed part, as long as the bracket 4 is fixedly disposed on the housing 1. In embodiments where the bracket 4 is sandwiched between the first housing 14 and the second housing 15, the bracket 4 can be an integrally formed part with the first housing 14 and / or the second housing 15, or the bracket 4, the first housing 14, and the second housing 15 can be three separate parts, as long as the bracket 4, the first housing 14, and the second housing 15 are fixedly disposed.
[0036] The crankshaft 21 is rotatably disposed within the housing 1 to drive the moving scroll 31 to rotate relative to the stationary scroll 32. The crankshaft 21 passes through the bracket 4 and a first mating bearing 212 is provided between the crankshaft 21 and the bracket 4 so that the bracket 4 can support the crankshaft 21.
[0037] The moving scroll 31 is located on one side of the bracket 4. One end of the crankshaft 21 is connected to the moving scroll 31 through the eccentric sleeve 24. A second mating bearing 25 is provided between the eccentric sleeve 24 and the moving scroll 31. When the crankshaft 21 rotates, the moving scroll 31 is driven to perform a revolution translational motion under the transmission action of the eccentric sleeve 24 and the second mating bearing 25 to compress the refrigerant in the compression chamber 33.
[0038] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment of the present invention, the eccentric sleeve 24 includes a main body 241 and a limiting member 242. The main body 241 and the limiting member 242 are separately machined parts. The main body 241 is fixed to the crankshaft 21 by a connecting assembly. The aforementioned second mating bearing 25 is disposed between the outer peripheral wall of the main body 241 and the moving scroll 31. The limiting member 242 is fixed to the main body 241 and is located between the second mating bearing 25 and the first mating bearing 212. The limiting member 242 is adapted to abut against the second mating bearing 25 to limit the axial displacement of the second mating bearing 25 and ensure the stability of the transmission between the eccentric sleeve 24 and the moving scroll 31.
[0039] According to the horizontal scroll compressor 100 of this utility model embodiment, the main body 241 and the limiting member 242 are separately machined parts. That is, the main body 241 and the limiting member 242 can be machined separately, and then the limiting member 242 is fixed to the main body 241 to form the eccentric sleeve 24. Compared with the one-piece eccentric sleeve 24 in related technologies, the eccentric sleeve 24 in this utility model embodiment is easier to machine, which is beneficial to improving the machining accuracy of the eccentric sleeve 24, increasing the production speed of the eccentric sleeve 24, and reducing the cost of the eccentric sleeve 24, thereby reducing the cost of the horizontal scroll compressor 100.
[0040] In some embodiments, the main body 241 is cylindrical in shape, allowing the outer diameter of the main body 241 to be precision ground using a centerless grinding process, effectively improving the machining accuracy and speed of the main body 241. The limiting member 242 is formed into a ring shape and is fitted onto the main body 241. The limiting member 242 can be formed using a sheet metal stamping process, effectively improving the machining speed of the eccentric sleeve 24.
[0041] In this embodiment of the utility model, the main body 241 and the limiting member 242 have simple structures, which improves the overall processing speed of the eccentric sleeve 24 and reduces the cost of the eccentric sleeve 24.
[0042] It should be understood that the main body 241 and the limiting member 242 can also be processed by other processing methods, and this utility model does not limit them.
[0043] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the thickness of the limiting member 242 is t, where 1mm ≤ t ≤ 5mm.
[0044] If the thickness t of the limiting component 242 is less than 1 mm, the strength of the limiting component 242 will be too low, and the limiting component 242 will be prone to deformation, affecting the use of the eccentric sleeve 24. If the thickness t of the limiting component 242 is greater than 5 mm, the limiting component 242 will be more difficult to process, and the cost of the eccentric sleeve 24 will increase.
[0045] In this embodiment of the invention, the thickness t of the limiting member 242 is limited to 1mm ≤ t ≤ 5mm, ensuring that the limiting member 242 has sufficient strength, improving the reliability of the eccentric sleeve 24, and reducing the cost of the eccentric sleeve 24. In some specific embodiments, the thickness t of the limiting member 242 is any one of 1mm, 2mm, 3mm, 4mm, and 5mm, or a range between any two.
[0046] In some further embodiments, the limiting member 242 is interference-fitted with the main body member 241.
[0047] In this embodiment of the utility model, the limiting member 242 is tightly connected to the main body member 241 and is not easy to loosen, which ensures the overall strength of the eccentric sleeve 24 and the reliability of the eccentric sleeve 24. Furthermore, no other fasteners are required between the limiting member 242 and the main body member 241, which simplifies the structure of the eccentric sleeve 24 and further reduces the cost of the eccentric sleeve 24.
[0048] It should be understood that in other embodiments, the limiting member 242 can also be fixed to the main body member 241 by means of threaded connection, snap-fit, etc. As long as the limiting member 242 can be fixed to the main body member 241, this utility model does not limit the specific connection method.
[0049] In some embodiments, the main body includes a first part 2411 and a second part 2412 connected together. A second mating bearing 25 is disposed on the first part 2411. The outer diameter of the first part 2411 is d0. The limiting member 242 is interference-fitted with the second part 2412. The outer diameter of the second part 2412 is d1. The inner diameter of the limiting member 242 is D2. The interference between the limiting member 242 and the second part 2412 is Δ, where Δ = d1 - D2. The eccentric sleeve 24 satisfies:
[0050] like If the value is less than 0.003, it indicates that the interference Δ between the limiting member 242 and the second part 2412 is too small compared to the outer diameter d0 of the first part 2411, resulting in poor connection strength between the main body 241 and the limiting member 242, affecting the overall strength of the eccentric sleeve 24; if If the value is greater than 0.01, it will increase the difficulty of the interference fit between the main body 241 and the limiting part 242, and increase the processing cost of the eccentric sleeve 24.
[0051] In this embodiment of the utility model, the eccentric sleeve 24 satisfies: This ensures sufficient connection strength between the main body 241 and the limiting part 242, while also reducing the difficulty of interference fit between the main body 241 and the limiting part 242.
[0052] In some specific embodiments, It equals any one of the point values of 0.003, 0.005, 0.007, 0.008, and 0.01, or any range between two of them.
[0053] It should be noted that the specific values of the outer diameter d0 of the first part 2411, the outer diameter d1 of the second part 2412, and the inner diameter D2 of the limiting member 242 can be the values measured before the limiting member 242 and the second part 2412 are interference-fitted, or the values measured after the limiting member 242 and the second part 2412 are interference-fitted and then disassembled.
[0054] In some embodiments, the main body includes a first part 2411 and a second part 2412 connected together, a second mating bearing 25 is disposed on the first part 2411, a limiting member 242 is interference-fitted with the second part 2412, the outer diameter of the first part 2411 is larger than the outer diameter of the second part 2412 to define a stop step 2415, and the stop step 2415 is adapted to define the position of the limiting member 242.
[0055] When the main body 241 and the limiting member 242 are connected by an interference fit, the position of the limiting member 242 can be restricted by the stop step 2415, so as to prevent the limiting member 242 from being installed into the first part 2411 and reduce the failure rate of the eccentric sleeve 24 machining.
[0056] It should be understood that the limiting member 242 can stop the stop step 2415, or it can be set at a distance from the stop step 2415.
[0057] In some embodiments, the main body 241 is provided with an eccentric hole 2413, which penetrates the main body 241 along its axial direction. The central axis of the eccentric hole 2413 is spaced apart from the central axis of the main body 241. The main body 241 is fixed to the crankshaft 21 by a connecting assembly, which includes a crank pin 26 disposed on the crankshaft 21 and inserted into the eccentric hole 2413.
[0058] In this embodiment of the utility model, the main body 241 is also provided with a self-aligning limiting groove 2414 on the side facing the crankshaft 21. The self-aligning limiting groove 2414 is formed as an arc-shaped groove surrounding the eccentric hole 2413. The crankshaft 21 is provided with a slider inserted into the self-aligning limiting groove 2414. The slider can be slidably disposed in the self-aligning limiting groove 2414 so as to adjust the eccentricity of the eccentric sleeve 24.
[0059] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments, the horizontal scroll compressor 100 includes: a housing 1, a drive assembly 2 and a compression assembly 3, wherein the drive assembly 2 and the compression assembly 3 are respectively disposed on the housing 1, and the drive assembly 2 is adapted to drive the compression assembly 3 to compress the refrigerant.
[0060] The housing 1 contains a high-pressure chamber 11, a low-pressure chamber 12, and an oil storage chamber 13. The oil storage chamber 13 is connected to the high-pressure chamber 11. The housing 1 has an air inlet 141 connected to the low-pressure chamber 12 and an air outlet 151 connected to the high-pressure chamber 11. The air inlet 141 and the air outlet 151 are used to connect to an external working circuit. The refrigerant in the external working circuit can enter the horizontal scroll compressor 100 through the air inlet 141, and the refrigerant compressed by the compression assembly 3 can be discharged through the air outlet 151 and re-enter the external working circuit.
[0061] The drive assembly 2 is located within the low-pressure chamber 12. The housing 1 is equipped with a support 4. The drive assembly 2 includes a crankshaft 21 passing through the support 4. The compression assembly 3 includes a moving scroll 31 and a stationary scroll 32. The stationary scroll 32 is located on the housing 1 and is stationary relative to it. The moving scroll 31 meshes with the stationary scroll 32, forming a compression chamber 33 between them. The moving scroll 31 is rotatable relative to the stationary scroll 32. The crankshaft 21 of the drive assembly 2 is connected to the moving scroll 31, meaning that the drive assembly 2 can drive the moving scroll 31 to rotate relative to the stationary scroll 32 via the crankshaft 21, allowing the compression assembly 3 to compress the refrigerant.
[0062] An electrical control cavity is also provided inside the housing 1, and an electrical control module is provided inside the electrical control cavity. The electrical control module is suitable for controlling the operating state of the scroll compressor 100. Specifically, the drive component 2 is connected to the electrical control module, so that the electrical control module can control the rotation state of the crankshaft 21, thereby controlling the operating state of the scroll compressor 100.
[0063] The intake port of the compression chamber 33 is connected to the low-pressure chamber 12, and the exhaust port 331 of the compression chamber 33 is connected to the high-pressure chamber 11. Therefore, when the horizontal scroll compressor 100 is working, the drive assembly 2 drives the moving scroll 31 to rotate relative to the stationary scroll 32 through the crankshaft 21, so that the compression assembly 3 can compress the refrigerant. The refrigerant in the external working circuit can enter the low-pressure chamber 12 through the intake port 141, and then enter the compression chamber 33 through the intake port. The compressed high-pressure refrigerant enters the high-pressure chamber 11 through the exhaust port 331, and then is discharged through the outlet port 151 and re-enters the external working circuit.
[0064] In this embodiment of the present invention, a back pressure cavity 41 is provided between the moving scroll 31 and the support 4. The gas in the back pressure cavity 41 can exert a force on the moving scroll 31 to ensure the axial balance of the moving scroll 31.
[0065] The horizontal scroll compressor 100 also includes multiple throttling elements 5. The oil storage chamber 13 and the back pressure chamber 41 are connected through the throttling elements 5, and the back pressure chamber 41 and the low pressure chamber 12 are connected through the throttling elements 5. At least one throttling element 5 is configured as a capillary structure.
[0066] It should be noted that the fluid discharged from the compression chamber 33 through the exhaust port 331 is a mixture of refrigerant and refrigeration oil. The high-pressure chamber 11 is equipped with an oil separator 16, which separates the refrigerant and refrigeration oil mixture into oil and gas. The separated refrigerant is discharged through the exhaust port 151, and the separated refrigeration oil enters the oil storage chamber 13 of the high-pressure chamber 11. The refrigeration oil in the oil storage chamber 13 can enter the back pressure chamber 41 through the throttling element 5 to lubricate the friction pairs within the back pressure chamber 41. The refrigeration oil in the back pressure chamber 41 can also enter the low-pressure chamber 12 through the throttling element 5 to lubricate the friction pairs within the low-pressure chamber 12.
[0067] In the above technical solution, the oil storage chamber 13 can be connected to the back pressure chamber 41 through a capillary tube. The medium in the oil storage chamber 13 can enter the back pressure chamber 41 after being throttled by the capillary tube. The throttling effect of the capillary tube is only related to the inner diameter and length of the capillary tube, that is, the throttling pressure reduction value of the capillary tube is stable. Since the oil storage chamber 13 is connected to the high pressure chamber 11, the pressure in the oil storage chamber 13 is the same as the pressure in the high pressure chamber 11. After the medium in the oil storage chamber 13 is throttled and depressurized by the capillary tube, the medium entering the back pressure chamber 41 is depressurized to the set value, thereby enabling the back pressure chamber 41 to obtain a stable back pressure value. The performance of the horizontal scroll compressor 100 is more likely to meet the design expectations. In addition, in this embodiment of the present invention, the back pressure chamber 41 and the low pressure chamber 12 can also be connected through a capillary tube, which reduces the influence of the medium flowing out of the back pressure chamber 41 on the pressure in the low pressure chamber 12 and ensures the reliability of the horizontal scroll compressor 100.
[0068] In some specific embodiments, the housing 1 includes a first housing 14 and a second housing 15. The first housing 14 is open on the side facing the second housing 15. A bracket 4 is disposed at the opening of the first housing 14 and closes the opening of the first housing 14. The low-pressure chamber 12 is defined between the first housing 14 and the bracket 4. The air inlet 141 is formed on the first housing 14. A stationary scroll 32 is disposed on the side of the bracket 4 away from the first housing 14. A moving scroll 31 is disposed between the bracket 4 and the stationary scroll 32, such that the back pressure chamber 41 is defined between the bracket 4 and the moving scroll 31, and the compression chamber 33 is defined between the moving scroll 31 and the stationary scroll 32.
[0069] The second housing 15 is located on the side of the stationary vortex disk 32 away from the support 4. That is, the stationary vortex disk 32 is sandwiched between the support 4 and the second housing 15. The second housing 15 is provided with the aforementioned high-pressure chamber 11 and air outlet 151.
[0070] In this embodiment of the invention, the connection between the compression component 3 and the housing 1 is simple, which improves the assembly efficiency of the horizontal scroll compressor 100.
[0071] In some specific embodiments, the crankshaft 21 is located inside the first housing 14 and is rotatable relative to the first housing 14. The first housing 14 is provided with a third mating bearing 211 for supporting the crankshaft 21, and the bracket 4 is provided with a first mating bearing 212 for supporting the crankshaft 21. That is, one end of the crankshaft 21 is rotatably mounted on the first housing 14 via the third mating bearing 211, and the other end of the crankshaft 21 is rotatably mounted on the bracket 4 via the first mating bearing 212.
[0072] The drive assembly 2 also includes a stator 22 and a rotor 23. The stator 22 is disposed on the inner wall of the first housing 14, and the rotor 23 is sleeved on the crankshaft 21. The stator 22 and the rotor 23 are coupled together. When the drive assembly 2 is working, the stator 22 drives the crankshaft 21 to rotate through the rotor 23, so that the crankshaft 21 can drive the rotating scroll 31 to rotate.
[0073] The compression assembly 3 includes a moving scroll 31, a stationary scroll 32, and an anti-rotation structure. The stationary scroll 32 is located on the side of the support 4 facing away from the first housing 14 and is fixedly mounted relative to the support 4. The stationary scroll 32 includes an end plate and a fixed scroll. The moving scroll 31 is located on the side of the stationary scroll 32 facing the support 4. The moving scroll 31 includes an end plate and a moving scroll. The fixed scroll and the moving scroll mesh with each other, thereby defining a compression cavity 33 between the fixed scroll and the moving scroll. The anti-rotation structure is used to limit the rotation of the moving scroll 31 while allowing the moving scroll 31 to perform a revolution-translational motion relative to the stationary scroll 32.
[0074] An eccentric sleeve 24 is provided at one end of the crankshaft 21 facing the moving scroll 31. The crankshaft 21 is adapted to drive the moving scroll 31 to rotate through the eccentric sleeve 24. A second mating bearing 25 is provided between the eccentric sleeve 24 and the moving scroll 31 so that the crankshaft 21 can drive the moving scroll 31 to perform a rotary translational motion relative to the stationary scroll 32.
[0075] When the horizontal scroll compressor 100 is working, the stator 22 drives the crankshaft 21 to rotate through the rotor 23. The crankshaft 21 drives the moving scroll 31 to revolve relative to the stationary scroll 32 through the eccentric sleeve 24, so that the refrigerant can be compressed in the compression chamber 33. The refrigerant in the external working circuit is drawn into the low-pressure chamber 12 through the air inlet 141, and then into the compression chamber 33 through the air intake for compression. The compressed high-pressure refrigerant enters the high-pressure chamber 11 through the exhaust port 331, and then is discharged through the air outlet 151.
[0076] In this embodiment of the invention, the drive assembly 2 inside the horizontal scroll compressor 100 has a simple structure, which reduces the cost of the horizontal scroll compressor 100.
[0077] In some embodiments, the stationary vortex disk 32 is provided with a first mounting hole 321 for placing the throttling element 5. The two ends of the first mounting hole 321 are respectively connected to the oil storage chamber 13 and the back pressure chamber 41. The throttling element 5 in the first mounting hole 321 is configured as a capillary structure.
[0078] In this embodiment of the invention, the structure in which the oil storage chamber 13 and the back pressure chamber 41 are connected is simple, which reduces the cost of the horizontal scroll compressor 100.
[0079] In some further embodiments, a connector 6 is provided between the throttling element 5 and the first mounting hole 321. The connector 6 has a mounting through hole 61 and a flow area 62 communicating with the mounting through hole 61. At least a portion of the throttling element 5 is located within the mounting through hole 61.
[0080] Through the above technical solution, the throttling element 5 is installed in the first mounting hole 321 through the connector 6, which improves the installation efficiency of the throttling element 5. Furthermore, a part of the throttling element 5 is located in the mounting through hole 61 of the connector 6, which can protect this part of the throttling element 5 and reduce the risk of deformation of the throttling element 5.
[0081] In some specific embodiments, the capillary structure includes a high-pressure end and a low-pressure end, the medium within the capillary structure is adapted to flow from the high-pressure end to the low-pressure end, and the high-pressure end of the capillary structure is located within the mounting through hole 61.
[0082] Through the above technical solution, the high-pressure medium needs to enter the installation through hole 61 through the flow area 62 before it can enter the capillary structure, which reduces the turbulence of the medium entering the capillary structure and improves the smoothness of the medium flow in the capillary structure.
[0083] In some further embodiments, the flow area 62 is a plurality of perforations on the outer peripheral wall of the connector 6. By setting the perforations on the outer peripheral wall of the connector 6, the high-pressure medium is prevented from directly rushing into the capillary structure, and the turbulence of the medium entering the capillary structure is further reduced.
[0084] In some specific embodiments, the capillary structure and the connector 6 are injection molded together. It should be understood that in other embodiments, the capillary structure and the connector 6 can also be connected by other means such as snap-fitting or bonding. This utility model does not limit this.
[0085] In some embodiments, a sealing element 7 is provided between the connector 6 and the inner wall of the mounting hole, which reduces the risk of the medium passing between the connector 6 and the inner wall of the mounting hole, ensuring that the medium can only pass through the throttling element 5, making the throttling effect more controllable and ensuring the performance of the horizontal scroll compressor 100.
[0086] In some specific embodiments, the outer peripheral wall of the connector 6 is provided with a mounting groove 63, and the seal 7 is constructed as a sealing ring disposed in the mounting groove 63.
[0087] In this embodiment of the invention, the installation method of the sealing element 7 is simple, which improves the assembly efficiency of the horizontal scroll compressor 100.

That is, the main body 241 and the limiting member 242 can be processed separately, and then the limiting member 242 is fixed to the main body 241 to form the eccentric sleeve 24. Compared with the one-piece eccentric sleeve 24 in related technologies, the eccentric sleeve 24 in the embodiment of the present invention is easier to process, which is beneficial to improving the processing accuracy of the eccentric sleeve 24, increasing the production speed of the eccentric sleeve 24, and reducing the cost of the eccentric sleeve 24, thereby reducing the cost of the horizontal scroll compressor 100, that is, reducing the cost of the air conditioner.

That is, the main body 241 and the limiting member 242 can be machined separately, and then the limiting member 242 is fixed to the main body 241 to form the eccentric sleeve 24. Compared with the one-piece eccentric sleeve 24 in related technologies, the eccentric sleeve 24 in this embodiment of the present invention is easier to machine, which is beneficial to improving the machining accuracy of the eccentric sleeve 24, increasing the production speed of the eccentric sleeve 24, and reducing the cost of the eccentric sleeve 24, thereby reducing the cost of the horizontal scroll compressor 100, that is, reducing the cost of the air conditioner.
