Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a horizontal compressor and a vehicle including the horizontal compressor. Background Art

[0002] During the operation of a rotary compressor, due to the compression of refrigerant gas, there is relative movement and friction between various components. The presence of lubricating oil ensures the reliable operation of each component, thereby ensuring the reliability of the compressor. In the traditional household field, rotary compressors are widely used and generally have a vertical structure. To ensure the lubrication of each component, oil is usually pumped by a crankshaft and oil supply holes are provided on the crankshaft. The lubricating oil is transmitted to various positions of the internal pump body of the compressor through the centrifugal force generated by rotation via the oil supply holes.

[0003] However, in the automotive field, due to different installation methods, compressors are usually arranged in a horizontal structure. As the vehicle travels on different road surfaces, the compressor will experience various vibrations and bumps, and the lubricating oil inside the compressor will also have various unstable bumps. At this time, the method of only bringing oil into the compressor through the centrifugal force of the oil supply holes in the crankshaft cannot ensure the lubrication of each component, thereby affecting the reliability of the product. Summary of the Utility Model

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the utility model is to provide a horizontal compressor that can ensure sufficient lubrication of each component during operation.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model provides a horizontal compressor, including: a housing with a hollow interior forming a cavity; an intermediate partition body disposed inside the housing and separating the cavity into a low-pressure chamber and a high-pressure chamber, and an oil sump is provided at the bottom of the high-pressure chamber; a compression assembly disposed in the high-pressure chamber, with a main bearing and a sub-bearing respectively installed on both side surfaces of the two ends of the compression assembly. The main bearing is installed on the intermediate partition body and penetrates through the intermediate partition body, so that one side surface of the main bearing is located in the high-pressure chamber and the other side surface is located in the low-pressure chamber. The bottom of the main bearing is immersed in the oil sump and is provided with an oil suction channel communicating with the oil sump; a crankshaft supported by the main bearing and the sub-bearing, one end of the crankshaft is provided with an eccentric portion cooperating with the compression assembly, and the other end is located in the low-pressure chamber and connected to a motor. An axial through hole is formed inside the crankshaft along the axis, one end of the through hole is separated from the high-pressure chamber, and the other end is connected to the low-pressure chamber; a first oil passage channel communicating with the low-pressure chamber is provided between the crankshaft and the main bearing, a second oil passage channel is provided between the crankshaft and the compression assembly, a third oil passage channel communicating the second oil passage channel with the through hole is provided between the crankshaft and the sub-bearing, and the end of the oil suction channel away from the oil sump is communicated to the first oil passage channel and the second oil passage channel.

[0007] Preferably, the minimum spacing dimension between the bottom of the main bearing and the housing is 1 mm - 4 mm.

[0008] Preferably, the oil suction channel has an oil suction port immersed in the oil sump. The oil suction port is located on the outer peripheral side surface of the main bearing, and the position where the oil suction port is located is at the lowest point of the outer peripheral side surface of the main bearing or deviates from the lowest point of the outer peripheral side surface of the main bearing by a set angle.

[0009] Preferably, the angle at which the position where the oil suction port is located circumferentially deviates from the lowest point of the outer peripheral side surface of the main bearing is -35° to 35°.

[0010] Preferably, the oil suction channel extends radially along the main bearing.

[0011] Preferably, the cross-sectional aperture of the oil suction channel is 3 mm - 5 mm.

[0012] Preferably, the oil suction channel is a straight cylindrical shape with a constant cross-section, or the oil suction channel includes a small-diameter section and a large-diameter section connected in a stepped shape. The end of the large-diameter section away from the small-diameter section is immersed in the oil sump. The cross-sectional aperture of the large-diameter section is 4 mm - 5 mm, and the cross-sectional aperture of the small-diameter section is 3 mm - 4 mm.

[0013] Preferably, the depth of the area of the oil suction port corresponding to the oil sump is not less than the depth of the area of the oil sump where the auxiliary bearing is located.

[0014] Preferably, the cavity wall contour of the high-pressure chamber is in a chamfered or tapered shape. The chamfered shape is machined with an inclined chamfer at the end close to the intermediate partition body, and the diameter of the tapered shape gradually decreases in the direction away from the intermediate partition body.

[0015] The present utility model also provides a vehicle, including the horizontal compressor as described above.

[0016] Compared with the prior art, the present utility model has significant progress:

[0017] The horizontal compressor of the present utility model realizes continuous oil suction from the oil sump by the oil suction channel on the main bearing and supplies it to the inside of the compressor to lubricate the main bearing, auxiliary bearing, and compression assembly, ensuring sufficient lubrication of each component during the operation of the compressor, thereby ensuring the reliability of the compressor operation. By opening an oil suction channel on the main bearing, on the one hand, since the main bearing is closer to the oil sump at the bottom of the high-pressure chamber, it is easier to suck oil and send it to the inside of the compressor when the compressor bumps and vibrates under harsh road conditions, thus ensuring sufficient lubrication of each component of the compressor; on the other hand, the main bearing is installed and fixed on the intermediate partition body, with higher connection strength and less deformation, so opening an oil suction channel on this main bearing is more stable and reliable. Therefore, the horizontal compressor of the present utility model has high overall reliability, simple manufacturing process, does not require additional components, and opening an oil suction channel on the main bearing can also achieve the effect of weight reduction and cost reduction.

[0058] Embodiment 1

[0059] As Figures 1 to 6 shown, it is the first embodiment of the horizontal compressor provided by the present utility model.

[0060] Refer to Figure 1 and Figure 2 , the horizontal compressor of this Embodiment 1 includes a housing 1, an intermediate partition body 2, a compression assembly 4, a main bearing 5, a sub-bearing 6, and a crankshaft 7.

[0061] Among them, the interior of the housing 1 is hollow to form a cavity. The intermediate partition body 2 is arranged inside the housing 1. The intermediate partition body 2 divides the internal cavity of the housing 1 into a low-pressure chamber 101 and a high-pressure chamber 102. In a preferred embodiment, the housing 1 may include a front housing 11 and a rear housing 12 arranged horizontally. Both the front housing 11 and the rear housing 12 are hollow structures inside. The intermediate partition body 2 is arranged between the front housing 11 and the rear housing 12 and is fixedly connected to the front housing 11 and the rear housing 12. The low-pressure chamber 101 is formed by the intermediate partition body 2 and the front housing 11, and the high-pressure chamber 102 is formed by the intermediate partition body 2 and the rear housing 12.

[0062] The compression assembly 4 is disposed within the high-pressure chamber 102. A main bearing 5 and an auxiliary bearing 6 are respectively mounted on both side surfaces at the two ends of the compression assembly 4. The main bearing 5 is located on the side of the compression assembly 4 close to the intermediate partition body 2. The crankshaft 7 is supported by the main bearing 5 and the auxiliary bearing 6, and the crankshaft 7 passes through the intermediate partition body 2 such that both end portions of the crankshaft 7 are respectively located within the low-pressure chamber 101 and the high-pressure chamber 102. An eccentric portion 71 is provided at one end portion of the crankshaft 7 located within the high-pressure chamber 102, and the eccentric portion 71 is engaged with the compression assembly 4. The other end portion of the crankshaft 7 located within the low-pressure chamber 101 is connected to the motor 8. The motor 8 is located within the low-pressure chamber 101 and fixedly mounted on the housing 1 (front housing 11), and the crankshaft 7 is driven to rotate by the rotor of the motor 8. The compression assembly 4 includes a cylinder 41 and a piston 42. The cylinder 41 is a cylinder body with a hollow interior. Both side surfaces at the two ends of the cylinder 41 are respectively connected to the main bearing 5 and the auxiliary bearing 6. The eccentric portion 71 of the crankshaft 7 is located inside the cylinder 41, and the piston 42 is sleeved on the eccentric portion 71. The low-pressure chamber 101 is provided with an air inlet for introducing low-pressure gas into the low-pressure chamber 101. An air passage is provided on the intermediate partition body 2 and the cylinder 41 for communicating the low-pressure chamber 101 with the interior of the cylinder 41 to introduce the low-pressure gas within the low-pressure chamber 101 into the interior of the cylinder 41. By driving the crankshaft 7 to rotate through the motor 8, the eccentric portion 71 and the piston 42 are driven to eccentrically operate inside the cylinder 41, and the gas inside the cylinder 41 can be compressed to obtain high-pressure gas with an increased pressure. The high-pressure gas is discharged into the high-pressure chamber 102 through the air outlet on the cylinder 41. Therefore, the air pressure within the high-pressure chamber 102 is greater than the air pressure within the low-pressure chamber 101, forming a pressure difference. The high-pressure chamber 102 is provided with an air outlet for discharging the high-pressure gas within the high-pressure chamber 102.

[0063] In the first embodiment, the main bearing 5 is mounted on the intermediate partition body 2 and passes through the intermediate partition body 2 such that one side surface of the main bearing 5 is located within the high-pressure chamber 102, and the other side surface of the main bearing 5 is located within the low-pressure chamber 101. Preferably, the main bearing 5 is directly connected and fixed to the intermediate partition body 2 by bolts. A neck extends axially along the middle of one side surface of the main bearing 5 that abuts against the intermediate partition body 2, and the main bearing 5 passes through the intermediate partition body 2 through this neck. An oil sump 3 is provided at the bottom of the high-pressure chamber 102. The bottom of the main bearing 5 is immersed in the oil sump 3, and an oil suction channel 50 communicating with the oil sump 3 is provided at the bottom of the main bearing 5.

[0064] An axial through hole 70 is formed along the interior of the crankshaft 7. One end of the through hole 70 located within the high-pressure chamber 102 is separated from the high-pressure chamber 102 and not interconnected, while one end of the through hole 70 located within the low-pressure chamber 101 is in communication with the low-pressure chamber 101. Thus, the air pressure within the through hole 70 is equal to the air pressure within the low-pressure chamber 101 and forms a pressure difference with the air pressure within the high-pressure chamber 102. Preferably, one end of the through hole 70 located within the high-pressure chamber 102 is separated from the high-pressure chamber 102 by an auxiliary bearing cover 60. The auxiliary bearing cover 60 is provided at one end of the auxiliary bearing 6 away from the compression assembly 4 and is hermetically connected to the auxiliary bearing 6. Specifically, the end of the auxiliary bearing 6 can be hermetically connected to the auxiliary bearing cover 60. One end of the crankshaft 7 located within the high-pressure chamber 102 is supported within the auxiliary bearing 6 and does not protrude beyond the auxiliary bearing 6, such that one end of the through hole 70 located within the high-pressure chamber 102 is separated from the high-pressure chamber 102 by the auxiliary bearing cover 60 and not interconnected. One end of the crankshaft 7 located within the low-pressure chamber 101 passes through the rotor of the motor 8, such that one end of the through hole 70 located within the low-pressure chamber 101 is in communication with the low-pressure chamber 101.

[0065] A first oil passage 91 is provided between the crankshaft 7 and the main bearing 5, and the first oil passage 91 is in communication with the low-pressure chamber 101. A second oil passage 92 is provided between the crankshaft 7 and the compression assembly 4, and a third oil passage 93 is provided between the crankshaft 7 and the auxiliary bearing 6. The third oil passage 93 connects the second oil passage 92 and the through hole 70 of the crankshaft 7, such that the second oil passage 92 and the third oil passage 93 are in communication with the low-pressure chamber 101. One end of the oil suction passage 50 away from the oil sump 3 is connected to the first oil passage 91 and the second oil passage 92, such that one end of the oil suction passage 50 away from the oil sump 3 is in communication with the low-pressure chamber 101.

[0066] The oil circuit of the horizontal compressor in the first embodiment is as Figure 1 shown by the arrows in the figure. Due to the pressure difference between the high-pressure chamber 102 and the low-pressure chamber 101, a pressure difference exists at both ends of the oil suction passage 50, such that the oil within the oil sump 3 at the bottom of the high-pressure chamber 102 can be sucked into the oil suction passage 50 and sent to the first oil passage 91 and the second oil passage 92 in two separate paths. The oil entering the first oil passage 91 lubricates the main bearing 5 and then flows into the low-pressure chamber 101. The oil entering the second oil passage 92 lubricates the compression assembly 4 and then enters the third oil passage 93 to lubricate the auxiliary bearing 6, and then flows into the through hole 70 of the crankshaft 7 and into the low-pressure chamber 101 from the through hole 70. The oil flowing into the low-pressure chamber 101 returns to the high-pressure chamber 102 along with the gas within the low-pressure chamber 101 through the gas passage and the oil-gas separation structure and converges into the oil sump 3. Thus, the oil suction passage 50 on the main bearing 5 continuously sucks oil from the oil sump 3 and supplies it to the interior of the compressor to lubricate the main bearing 5, the auxiliary bearing 6, and the compression assembly 4, ensuring sufficient lubrication of each component during the operation of the compressor, and thereby ensuring the reliability of the compressor operation.

[0067] In the horizontal compressor of the first embodiment, an oil suction channel 50 is provided in the main bearing 5. On the one hand, since the main bearing 5 is closer to the oil sump 3 at the bottom of the high-pressure chamber 102, it is easier to suck oil into and send it into the compressor during the bumpy vibration of the compressor under harsh road conditions, thus ensuring sufficient lubrication of all components of the compressor. On the other hand, the main bearing 5 is fixedly installed on the intermediate partition body 2, with higher connection strength and less deformation, so it is more stable and reliable to provide the oil suction channel 50 on the main bearing 5. Therefore, the horizontal compressor of the first embodiment has high overall reliability, simple manufacturing process, does not require additional components, and at the same time, providing the oil suction channel 50 on the main bearing 5 can also achieve the effect of weight reduction and cost reduction.

[0068] See Figures 1 to 4 , in the first embodiment, the first oil passage 91 between the crankshaft 7 and the main bearing 5 is preferably formed by a first oil groove provided on the outer peripheral wall of the crankshaft 7 and / or the inner peripheral wall of the main bearing 5, and the first oil groove is preferably spiral. A main bearing annular oil groove 51 is provided on one side surface of the end of the main bearing 5 located in the high-pressure chamber 102. The main bearing annular oil groove 51 communicates the first oil passage 91 and the second oil passage 92, and the end of the oil suction channel 50 away from the oil sump 3 communicates with the main bearing annular oil groove 51, thereby communicating the first oil passage 91 and the second oil passage 92.

[0069] The second oil passage 92 between the crankshaft 7 and the compression assembly 4 is provided between the eccentric portion 71 of the crankshaft 7 and the piston 42 of the compression assembly 4. The second oil passage 92 is preferably formed by a second oil groove provided on the outer peripheral wall of the eccentric portion 71 of the crankshaft 7, and the second oil groove is preferably spiral. The compression assembly 4 can be a single-stage compression structure, that is, it includes a set of cylinders 41 and pistons 42; the compression assembly 4 can also be a multi-stage compression structure, that is, it includes multiple sets of cylinders 41 and pistons 42, and adjacent sets of cylinders 41 and pistons 42 are separated from each other by an intermediate plate 43. There is a gap between the inner hole of the intermediate plate 43 and the crankshaft 7 for communicating the second oil grooves between adjacent sets of pistons 42 and the eccentric portion 71 of the crankshaft 7 to form the second oil passage 92.

[0070] The third oil passage 93 between the crankshaft 7 and the auxiliary bearing 6 is preferably formed by a third oil groove provided on the outer peripheral wall of the crankshaft 7 and / or the inner peripheral wall of the auxiliary bearing 6, and the third oil groove is preferably spiral. An auxiliary bearing annular oil groove 61 is provided on one side surface of the end of the auxiliary bearing 6 abutted against the compression assembly 4. The auxiliary bearing annular oil groove 61 communicates the second oil passage 92 and the third oil passage 93. A gap is formed between the end face of the end of the crankshaft 7 supported in the auxiliary bearing 6 and the auxiliary bearing cover 60. The end of the third oil passage 93 away from the auxiliary bearing annular oil groove 61 communicates with the shaft hole 70 of the crankshaft 7 through this gap, and thus communicates with the low-pressure chamber 101 through the shaft hole 70.

[0071] In the first embodiment, preferably, there is a gap between the bottom of the main bearing 5 and the housing 1 (the rear housing 12), which can store oil well and is beneficial for the oil suction channel 50 on the main bearing 5 to better suck in oil and send it to the inside of the compressor to fully lubricate the main bearing 5, the auxiliary bearing 6, and the compression assembly 4. Preferably, the minimum gap size between the bottom of the main bearing 5 and the housing 1 (the rear housing 12) is 1 mm - 4 mm.

[0072] Preferably, the maximum outer diameter of the overall structure of the compression assembly 4, the auxiliary bearing 6, and the auxiliary bearing cover 60 is smaller than the inner diameter of the high-pressure chamber 102. The inner diameter of the high-pressure chamber 102 is the inner diameter of the rear housing 12. The compression assembly 4, the auxiliary bearing 6, and the auxiliary bearing cover 60 are integrally installed on the main bearing 5 and form a gap with the housing 1 (the rear housing 12). Thus, the compression assembly 4, the auxiliary bearing 6, and the auxiliary bearing cover 60 are integrally supported by the main bearing 5, and the main bearing 5 is installed on the intermediate partition body 2 and forms a gap with the housing 1. Thus, the main bearing 5, the compression assembly 4, the auxiliary bearing 6, and the auxiliary bearing cover 60 are integrally supported by the intermediate partition body 2.

[0073] In the first embodiment, preferably, the cross-sectional aperture of the oil suction channel 50 on the main bearing 5 is 3 mm - 5 mm, which can ensure the oil supply amount while also ensuring that the oil suction channel 50 can effectively suck in oil under the pressure difference between the high-pressure chamber 102 and the low-pressure chamber 101.

[0074] In one implementation, the oil suction channel 50 is a straight cylindrical shape with a constant cross-section, which has the advantages of simple structure and convenient processing.

[0075] In another implementation, preferably, refer to Figure 3 Figure, the oil suction channel 50 includes a small-diameter section 501 and a large-diameter section 502 connected in a stepped shape. One end of the large-diameter section 502 away from the small-diameter section 501 is immersed in the oil sump 3, and one end of the small-diameter section 501 away from the large-diameter section 502 is connected to the main bearing annular oil groove 51. Preferably, the cross-sectional aperture of the large-diameter section 502 is 4 mm - 5 mm, and the cross-sectional aperture of the small-diameter section 501 is 3 mm - 4 mm. The two-stage stepped shape of the oil suction channel 50 can install an oil plug filter screen in the large-diameter section 502 to play a role in filtering impurities.

[0076] In the first embodiment, preferably, refer to Figure 3 and Figure 4 Figure, the oil suction channel 50 on the main bearing 5 has an oil suction port 500 immersed in the oil sump 3, and the oil suction port 500 is located on the outer peripheral side surface of the main bearing 5. Preferably, the oil suction channel 50 extends radially along the main bearing 5.

[0077] In one implementation, as shown in Figure 5As shown, the position of the oil suction port 500 of the oil suction channel 50 is at the lowest point on the outer peripheral side of the main bearing 5, that is, an oil suction port 500 is opened at a position directly below the outer peripheral side of the main bearing 5 and facing the oil sump 3, and extends into the main bearing 5 to form the oil suction channel 50.

[0078] In another embodiment, as Figure 6 shown, the position of the oil suction port 500 of the oil suction channel 50 deviates from the lowest point on the outer peripheral side of the main bearing 5 by a set angle, that is, an oil suction port 500 is opened at a position on the outer peripheral side of the main bearing 5 that deviates from the position directly below and facing the oil sump 3, and extends into the main bearing 5 to form the oil suction channel 50. Preferably, the angle at which the position of the oil suction port 500 deviates from the lowest point on the outer peripheral side of the main bearing 5 in the circumferential direction is -35° to 35°.

[0079] To ensure that the oil suction port 500 of the oil suction channel 50 can be immersed in the oil in the oil sump 3, the depth of the area of the oil suction port 500 of the oil suction channel 50 corresponding to the oil sump 3 is not less than the depth of the area of the oil sump 3 where the auxiliary bearing 6 is located, so as to ensure that there is enough oil stored in the area of the oil sump 3 where the oil suction port 500 of the oil suction channel 50 is located, thereby ensuring that the oil suction port 500 of the oil suction channel 50 can be immersed in the oil sump 3 and ensuring that the oil suction channel 50 can suck in oil.

[0080] In the first embodiment, the wall contour of the high-pressure chamber 102 is straight cylindrical, that is, the inner peripheral surface of the rear housing 12 is straight cylindrical, and this straight cylindrical shape is cylindrical. This makes the depth of the area of the oil suction port 500 of the oil suction channel 50 corresponding to the oil sump 3 the same as the depth of the area of the oil sump 3 where the auxiliary bearing 6 is located, which is beneficial to the uniform dispersion of the oil in the oil sump 3 and avoids the oil flowing and gathering in the area of the oil sump 3 where the auxiliary bearing 6 is located, thus reducing the amount of oil in the area of the oil sump 3 where the oil suction port 500 of the oil suction channel 50 is located.

[0081] Embodiment Two

[0082] As Figure 7 shown, this is the second embodiment of the horizontal compressor provided by the present utility model. Embodiment Two is basically the same as Embodiment One, and the same parts will not be described again. The differences are that in this Embodiment Two, the depth of the area of the oil suction port 500 of the oil suction channel 50 corresponding to the oil sump 3 is less than the depth of the area of the oil sump 3 where the auxiliary bearing 6 is located. Specifically, the wall contour of the high-pressure chamber 102 is chamfered, that is, the inner peripheral surface of the rear housing 12 is chamfered, and this chamfered shape has an inclined chamfer processed at one end close to the intermediate partition body 2, that is, an inclined chamfer is processed at one end of the wall contour of the high-pressure chamber 102 close to the intermediate partition body 2. Thus, more oil can be stored in the oil sump 3 at the inclined chamfer at the bottom of the high-pressure chamber 102, which is beneficial to ensuring that the oil suction port 500 of the oil suction channel 50 on the main bearing 5 can still be immersed in the oil sump 3 under more severe working conditions, thereby ensuring that the oil suction channel 50 can suck in oil.

[0083] Embodiment III

[0084] As Figure 8 shown, this is the third embodiment of the horizontal compressor provided by the present utility model. Embodiment III is basically the same as Embodiment I, and the same parts will not be described again. The difference is that in this Embodiment III, the depth of the area of the oil suction port 500 of the oil suction channel 50 corresponding to the oil sump 3 is less than the depth of the area of the oil sump 3 where the auxiliary bearing 6 is located. Specifically, the contour of the cavity wall of the high-pressure chamber 102 is conical, that is, the inner peripheral surface of the rear housing 12 is conical, and the diameter of this cone gradually decreases in the direction away from the intermediate partition body 2, that is, the diameter of the contour of the cavity wall of the high-pressure chamber 102 gradually decreases in the direction away from the intermediate partition body 2, presenting a frustum shape. This can make the oil in the oil sump 3 at the bottom of the high-pressure chamber 102 flow more easily towards the intermediate partition body 2 and reach the oil suction port 500 of the oil suction channel 50 on the main bearing 5, thus being more conducive to ensuring that the oil suction port 500 of the oil suction channel 50 sucks in oil.
