Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to a horizontal compressor and a vehicle comprising the horizontal compressor. Background Art

[0002] During the operation of the rotary compressor, due to the compression of refrigerant gas, there is relative movement between the various components to generate friction. The presence of lubricating oil ensures the reliable operation of the various components, 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 various components, oil is usually pumped through the crankshaft and an oil supply hole is opened on the crankshaft. The centrifugal force generated by the rotation transmits the lubricating oil through the oil supply hole to various positions of the pump body inside the compressor.

[0003] However, in the automotive field, due to different installation methods, the compressor is usually set as a horizontal structure. As the vehicle travels on different roads, the compressor will experience various vibrations and bumps, and the lubricating oil inside the compressor will also produce various unstable bumps. At this time, the method of only using the centrifugal force of the crankshaft oil supply hole to bring oil into the compressor cannot guarantee the lubrication of each component, thus affecting the reliability of the product. Summary of the invention

[0004] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a horizontal compressor which can ensure sufficient lubrication of various components during operation.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The present invention provides a horizontal compressor, comprising: a shell, the interior of which is hollow to form a cavity; a middle partition body, which is arranged inside the shell and divides the cavity into a low-pressure cavity and a high-pressure cavity, and an oil pool is arranged at the bottom of the high-pressure cavity; a compression assembly, which is arranged in the high-pressure cavity, and a main bearing and a secondary bearing are respectively installed on the side surfaces of both ends of the compression assembly, and the main bearing is installed on the middle partition body and penetrates the middle partition body, so that one end side surface of the main bearing is located in the high-pressure cavity, and the other end side surface is located in the low-pressure cavity, and the bottom of the main bearing is immersed in the oil pool and an oil suction channel connected to the oil pool is opened; a crankshaft, which consists of the main bearing and The crankshaft is supported by a secondary bearing, one end of which is provided with an eccentric portion that matches the compression assembly, and the other end is located in the low-pressure chamber and connected to the motor, the interior of the crankshaft is axially penetrated to form an axial hole, one end of the axial hole is separated from the high-pressure chamber, and the other end is connected to the low-pressure chamber; a first oil passage connected to the low-pressure chamber is provided between the crankshaft and the main bearing, a second oil passage is provided between the crankshaft and the compression assembly, a third oil passage connecting the second oil passage and the axial hole is provided between the crankshaft and the secondary bearing, and an end of the oil suction passage away from the oil pool is connected to the first oil passage and the second oil passage.

[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 pool, the oil suction port is located on the outer peripheral side of the main bearing, and the oil suction port is located at the lowest point of the outer peripheral side of the main bearing or deviates from the lowest point of the outer peripheral side of the main bearing by a set angle.

[0009] Preferably, the oil suction port is located at an angle of -35° to 35° away from the lowest point of the outer peripheral side surface of the main bearing in the circumferential direction.

[0010] Preferably, the oil suction passage extends in a radial direction of the main bearing.

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

[0012] Preferably, the oil suction channel is a straight cylinder with a uniform cross-section, or the oil suction channel includes a small diameter section and a large diameter section connected in a step-like shape, and one end of the large diameter section away from the small diameter section is immersed in the oil pool, the cross-sectional aperture of the large diameter section is 4mm to 5mm, and the cross-sectional aperture of the small diameter section is 3mm to 4mm.

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

[0014] Preferably, the cavity wall profile of the high-pressure cavity is chamfered or conical, the chamfered cavity has a chamfered angle at one end close to the middle partition body, and the diameter of the conical cavity gradually decreases in the direction away from the middle partition body.

[0015] The present invention also provides a vehicle, comprising the horizontal compressor as described above.

[0016] Compared with the prior art, the present invention has significant improvements:

[0017] The horizontal compressor of the present invention realizes that the oil suction channel on the main bearing continuously sucks oil from the oil pool and supplies it to the inside of the compressor to lubricate the main bearing, the auxiliary bearing, and the compression assembly, ensuring that all components are fully lubricated during the operation of the compressor, thereby ensuring the reliability of the operation of the compressor. The oil suction channel is opened on the main bearing. On the one hand, since the main bearing is closer to the oil pool at the bottom of the high-pressure chamber, it is easier to suck in and send oil to the inside of the compressor when the compressor is bumped and vibrated under harsh road conditions, thereby ensuring that all components of the compressor are fully lubricated; on the other hand, the main bearing is installed and fixed on the middle partition body, with higher connection strength and smaller deformation, so that the oil suction channel opened on this main bearing is more stable and reliable. Therefore, the horizontal compressor of the present invention has high overall reliability and a simple manufacturing process, and does not require the addition of additional components. At the same time, opening an oil suction channel on the main bearing can also achieve the effect of reducing weight and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Embodiment 1

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

[0060] See also Figure 1 and Figure 2 The horizontal compressor of the first embodiment includes a shell 1, a middle partition body 2, a compression assembly 4, a main bearing 5, a secondary bearing 6 and a crankshaft 7.

[0061] The shell 1 is hollow inside to form a cavity, and the middle partition body 2 is arranged inside the shell 1. The middle partition body 2 divides the internal cavity of the shell 1 into a low-pressure chamber 101 and a high-pressure chamber 102. In a preferred embodiment, the shell 1 may include a front shell 11 and a rear shell 12 arranged horizontally, and the front shell 11 and the rear shell 12 are both hollow structures inside. The middle partition body 2 is arranged between the front shell 11 and the rear shell 12, and is connected and fixed to the front shell 11 and the rear shell 12. The low-pressure chamber 101 is surrounded by the middle partition body 2 and the front shell 11, and the high-pressure chamber 102 is surrounded by the middle partition body 2 and the rear shell 12.

[0062] The compression assembly 4 is arranged in the high-pressure chamber 102, and the main bearing 5 and the auxiliary bearing 6 are respectively installed on the side surfaces of both ends of the compression assembly 4, and the main bearing 5 is located on the side of the compression assembly 4 close to the middle partition body 2. The crankshaft 7 is supported by the main bearing 5 and the auxiliary bearing 6, and the crankshaft 7 is passed through the middle partition body 2, so that the two ends of the crankshaft 7 are respectively located in the low-pressure chamber 101 and the high-pressure chamber 102. An eccentric portion 71 is provided at one end of the crankshaft 7 located in the high-pressure chamber 102, and the eccentric portion 71 cooperates with the compression assembly 4. The other end of the crankshaft 7 located in the low-pressure chamber 101 is connected to the motor 8. The motor 8 is located in the low-pressure chamber 101 and is 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 hollow cylinder body. The two end sides of the cylinder 41 are connected to the main bearing 5 and the auxiliary bearing 6 respectively. The eccentric part 71 of the crankshaft 7 is located inside the cylinder 41, and the piston 42 is sleeved on the eccentric part 71. The low-pressure chamber 101 is provided with an air inlet for introducing low-pressure gas into the low-pressure chamber 101. The middle partition body 2 and the cylinder 41 are provided with an air passage connecting the low-pressure chamber 101 and the inside of the cylinder 41, which is used to introduce the low-pressure gas in the low-pressure chamber 101 into the inside of the cylinder 41. The crankshaft 7 is driven to rotate by the motor 8, driving the eccentric part 71 and the piston 42 to eccentrically operate inside the cylinder 41, and the gas inside the cylinder 41 can be compressed to obtain high-pressure gas with 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 in the high-pressure chamber 102 is greater than the air pressure in the low-pressure chamber 101, forming a pressure difference. The high pressure chamber 102 is provided with an exhaust port for exhausting the high pressure gas in the high pressure chamber 102 .

[0063] In the first embodiment, the main bearing 5 is mounted on the intermediate partition body 2 and penetrates the intermediate partition body 2, so that one end side of the main bearing 5 is located in the high-pressure chamber 102, and the other end side of the main bearing 5 is located in the low-pressure chamber 101. Preferably, the main bearing 5 is directly connected and fixed to the intermediate partition body 2 by bolts, and the main bearing 5 is close to the middle of the side surface of the intermediate partition body 2 and has a neck extending axially and penetrates the intermediate partition body 2 through the neck. An oil pool 3 is provided at the bottom of the high-pressure chamber 102, and the bottom of the main bearing 5 is immersed in the oil pool 3, and an oil suction channel 50 connected to the oil pool 3 is opened at the bottom of the main bearing 5.

[0064] The crankshaft 7 is axially penetrated to form a shaft hole 70. One end of the shaft hole 70 located in the high-pressure chamber 102 is separated from the high-pressure chamber 102 and does not communicate with each other. One end of the shaft hole 70 located in the low-pressure chamber 101 is connected to the low-pressure chamber 101. The air pressure in the shaft hole 70 is equal to the air pressure in the low-pressure chamber 101 and forms a pressure difference with the air pressure in the high-pressure chamber 102. Preferably, the end of the shaft hole 70 located in the high-pressure chamber 102 is separated from the high-pressure chamber 102 by the auxiliary bearing cover 60. The auxiliary bearing cover 60 is provided at the end of the auxiliary bearing 6 away from the compression assembly 4 and is sealed and connected to the auxiliary bearing 6. Specifically, the end of the auxiliary bearing 6 is sealed and connected to the auxiliary bearing cover 60. The end of the crankshaft 7 located in the high-pressure chamber 102 is supported in the auxiliary bearing 6 and does not protrude from the auxiliary bearing 6, so that the end of the shaft hole 70 located in the high-pressure chamber 102 is separated from the high-pressure chamber 102 by the auxiliary bearing cover 60 and does not communicate with each other. One end of the crankshaft 7 located in the low-pressure chamber 101 passes through the rotor of the motor 8 , so that one end of the shaft hole 70 located in the low-pressure chamber 101 is connected to 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 connected to 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, and the third oil passage 93 connects the second oil passage 92 with the shaft hole 70 of the crankshaft 7, so that the second oil passage 92 and the third oil passage 93 are connected to the low-pressure chamber 101. One end of the oil suction passage 50 away from the oil pool 3 is connected to the first oil passage 91 and the second oil passage 92, so that the end of the oil suction passage 50 away from the oil pool 3 is connected to the low-pressure chamber 101.

[0066] The oil circuit of the horizontal compressor of the first embodiment is as follows Figure 1 As shown by the middle arrow, due to the pressure difference between the high-pressure chamber 102 and the low-pressure chamber 101, there is a pressure difference at both ends of the oil suction channel 50, so that the oil in the oil pool 3 at the bottom of the high-pressure chamber 102 can be sucked in through the oil suction channel 50 and sent to the first oil channel 91 and the second oil channel 92 in two ways. The oil entering the first oil channel 91 lubricates the main bearing 5 and then flows into the low-pressure chamber 101. The oil entering the second oil channel 92 lubricates the compression assembly 4 and then enters the third oil channel 93 to lubricate the auxiliary bearing 6, and then flows into the shaft hole 70 of the crankshaft 7, and flows into the low-pressure chamber 101 from the shaft hole 70. The oil flowing into the low-pressure chamber 101 returns to the high-pressure chamber 102 along with the gas in the low-pressure chamber 101 through the gas channel and the oil-gas separation structure and converges into the oil pool 3. Thereby, the oil suction channel 50 on the main bearing 5 continuously sucks oil from the oil pool 3 and supplies it to the inside of the compressor to lubricate the main bearing 5, the auxiliary bearing 6, and the compression assembly 4, ensuring sufficient lubrication of various components during the operation of the compressor, thereby ensuring the reliability of the compressor operation.

[0067] The horizontal compressor of the first embodiment of the present invention has an oil suction channel 50 on the main bearing 5. On the one hand, since the main bearing 5 is closer to the oil pool 3 at the bottom of the high-pressure chamber 102, it is easier to suck in and send oil to the inside of the compressor when the compressor is bumped and vibrated under bad road conditions, thereby ensuring that all parts of the compressor are fully lubricated; on the other hand, the main bearing 5 is installed and fixed on the middle partition body 2, with higher connection strength and smaller deformation, so that the oil suction channel 50 is opened on this main bearing 5. It is more stable and reliable. Therefore, the horizontal compressor of the first embodiment of the present invention has high overall reliability, and the manufacturing process is simple, and no additional parts need to be added. At the same time, opening the oil suction channel 50 on the main bearing 5 can also achieve the effect of reducing weight and reducing costs.

[0068] See also 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 or / and 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 the side surface of one end of the main bearing 5 located in the high pressure chamber 102, and the main bearing annular oil groove 51 connects the first oil passage 91 and the second oil passage 92. The end of the oil suction passage 50 away from the oil pool 3 is connected to the main bearing annular oil groove 51, thereby connecting 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. The second oil groove is preferably spiral. The compression assembly 4 may be a single-stage compression structure, i.e., it includes a group of cylinders 41 and pistons 42; the compression assembly 4 may also be a multi-stage compression structure, i.e., it includes multiple groups of cylinders 41 and pistons 42. Two adjacent groups of cylinders 41 and pistons 42 are separated from each other by an intermediate plate 43. There is a spacing space between the inner hole of the intermediate plate 43 and the crankshaft 7, which is used to connect the second oil groove between the two adjacent groups 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 or / and 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 the side surface of one end of the auxiliary bearing 6 close to the compression assembly 4, and the auxiliary bearing annular oil groove 61 connects the second oil passage 92 and the third oil passage 93. A gap is formed between the end surface of the crankshaft 7 supported in the auxiliary bearing 6 and the auxiliary bearing cover 60, and the end of the third oil passage 93 away from the auxiliary bearing annular oil groove 61 is connected to the shaft hole 70 of the crankshaft 7 through the gap, and then connected to 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 (rear housing 12), which can store oil well, and is conducive to the oil suction channel 50 on the main bearing 5 to better suck the 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 (rear housing 12) is 1mm-4mm.

[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, and 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 (rear housing 12), so that 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 middle partition body 2 and forms a gap with the housing 1, so that the main bearing 5, the compression assembly 4, the auxiliary bearing 6 and the auxiliary bearing cover 60 are integrally supported by the middle 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 to 5 mm, which ensures the oil supply while also ensuring that the oil suction channel 50 can effectively absorb oil under the pressure difference between the high-pressure chamber 102 and the low-pressure chamber 101 .

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

[0075] In another embodiment, preferably, see Figure 3 The oil suction channel 50 includes a small diameter section 501 and a large diameter section 502 connected in a step shape. The end of the large diameter section 502 away from the small diameter section 501 is immersed in the oil pool 3, and the 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 4mm to 5mm, and the cross-sectional aperture of the small diameter section 501 is 3mm to 4mm. The oil suction channel 50 adopts a two-stage step shape, and an oil plug filter can be installed in the large diameter section 502 to filter impurities.

[0076] In this embodiment 1, preferably, see Figure 3 and Figure 4 The oil suction channel 50 on the main bearing 5 has an oil suction port 500 immersed in the oil pool 3, and the oil suction port 500 is located on the outer peripheral side of the main bearing 5. Preferably, the oil suction channel 50 extends in the radial direction of the main bearing 5.

[0077] In one embodiment, if Figure 5As shown, the oil suction port 500 of the oil suction channel 50 is located at the lowest point of the outer peripheral side of the main bearing 5, that is, the oil suction port 500 is opened at a position directly below the outer peripheral side of the main bearing 5 and facing the oil pool 3 and extends into the inside of the main bearing 5 to form the oil suction channel 50.

[0078] In another embodiment, if Figure 6 As shown, the oil suction port 500 of the oil suction channel 50 is located at a set angle away from the lowest point of the outer peripheral side surface of the main bearing 5, that is, the oil suction port 500 is opened on the outer peripheral side surface of the main bearing 5 away from the position directly below and facing the oil pool 3 and extends into the main bearing 5 to form the oil suction channel 50. Preferably, the angle of the oil suction port 500 away from the lowest point of the outer peripheral side surface of the main bearing 5 along 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 pool 3, the depth of the area of ​​the oil suction port 500 of the oil suction channel 50 corresponding to the oil pool 3 is not less than the depth of the area of ​​the oil pool 3 where the auxiliary bearing 6 is located, so as to ensure that sufficient oil can be stored in the area of ​​the oil pool 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 pool 3 and ensuring that the oil suction channel 50 can suck in oil.

[0080] In the first embodiment, the cavity wall profile of the high pressure cavity 102 is straight-cylindrical, that is, the inner circumference of the rear housing 12 is straight-cylindrical, and the straight-cylindrical shape is cylindrical. As a result, the depth of the area corresponding to the oil pool 3 of the oil suction port 500 of the oil suction channel 50 is the same as the depth of the area of ​​the oil pool 3 where the auxiliary bearing 6 is located, which is conducive to uniform dispersion of the oil in the oil pool 3, and avoids the oil flowing to the area of ​​the oil pool 3 where the auxiliary bearing 6 is located, thereby reducing the amount of oil in the area of ​​the oil pool 3 where the oil suction port 500 of the oil suction channel 50 is located.

[0081] Embodiment 2

[0082] like Figure 7 As shown, it is the second embodiment of the horizontal compressor provided by the present invention. Embodiment 2 is basically the same as Embodiment 1, and the similarities are not repeated here. The difference is that in this embodiment 2, the depth of the area of ​​the oil suction port 500 of the oil suction channel 50 corresponding to the oil pool 3 is less than the depth of the area of ​​the oil pool 3 where the auxiliary bearing 6 is located. Specifically, the cavity wall profile of the high-pressure chamber 102 is chamfered, that is, the inner peripheral surface of the rear shell 12 is chamfered, and the chamfered type is processed with a chamfer at one end close to the middle partition body 2, that is, the cavity wall profile of the high-pressure chamber 102 is processed with a chamfer at one end close to the middle partition body 2, thereby allowing the oil pool 3 at the bottom of the high-pressure chamber 102 to store more oil at the chamfer, which is conducive 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 pool 3 under more severe working conditions, thereby ensuring that the oil suction channel 50 can suck oil.

[0083] Embodiment 3

[0084] like Figure 8 As shown, it is the third embodiment of the horizontal compressor provided by the present invention. Embodiment 3 is basically the same as Embodiment 1, and the similarities are not repeated here. The difference is that in this embodiment 3, the depth of the area of ​​the oil suction port 500 of the oil suction channel 50 corresponding to the oil pool 3 is less than the depth of the area of ​​the oil pool 3 where the auxiliary bearing 6 is located. Specifically, the cavity wall profile of the high-pressure chamber 102 is conical, that is, the inner peripheral surface of the rear shell 12 is conical, and the diameter of the cone gradually decreases in the direction away from the middle partition body 2, that is, the diameter of the cavity wall profile of the high-pressure chamber 102 gradually decreases in the direction away from the middle partition body 2, and is in the shape of a cone. As a result, the oil in the oil pool 3 at the bottom of the high-pressure chamber 102 can more easily flow toward the middle partition body 2 and flow to the oil suction port 500 of the oil suction channel 50 on the main bearing 5, which is more conducive to ensuring that the oil suction port 500 of the oil suction channel 50 sucks oil.

[0085] Embodiment 4

[0086] Based on the horizontal compressor of the present invention, the fourth embodiment of the present invention further provides a vehicle. The vehicle of the fourth embodiment includes the horizontal compressor of the present invention. The horizontal compressor can be any one of the horizontal compressors described in the above-mentioned first to third embodiments.

[0087] The above is only a preferred embodiment of the present invention.
