Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a compressor and a vehicle. Background Art
[0002] The compressor for electric vehicles is a positive displacement compressor with high efficiency, low noise and smooth operation. As the third-generation on-board compressor, it is widely used in automotive air-conditioning systems.
[0003] In recent years, with the development of new energy vehicles, the application scope has been continuously expanded, and the requirements for harsh working conditions have been gradually improved. Under the industry development trend, the performance, noise, vibration and durability of air-conditioning compressors in automobiles have been further improved. Among them, during the use of the compressor, it is necessary to provide oil to lubricate the friction pairs in the compressor to reduce the noise generated when the friction pairs are working, and reduce the performance loss caused by friction power. In the prior art, after the exhaust and oil are separated through the oil separation pipe in the exhaust cover, the oil enters the oil storage tank through the oil return hole of the exhaust cover. The oil in the oil storage tank finally returns to the oil return channel of the compressor through the throttling oil return mechanism, thereby lubricating the friction pairs in the compressor.
[0004] However, in actual use, since the throttling oil return mechanism is directly opposite to the oil return hole, the oil-gas mixed fluid after being diverted by the oil distribution pipe will flush the oil in the oil reservoir due to high speed and high pressure. The oil in the oil reservoir will churn due to the impact, resulting in the through hole connecting the oil reservoir and the throttling oil return mechanism not being completely immersed in the oil. The refrigerant leaks directly from the throttling oil return mechanism to the suction side of the compressor. The refrigerant leaks, the volumetric efficiency decreases, and the cooling capacity of the compressor decreases. In addition, when the refrigerant leaks through the throttling oil return mechanism, it occupies the fluid conveying space of the throttling oil return mechanism, and the oil conveyed to the return oil channel through the throttling oil return mechanism is reduced. The churning of the oil will also cause the refrigerant to be mixed and dissolved in the oil again, and the proportion of oil in the oil reservoir will decrease, thereby further reducing the proportion of oil in the return oil, resulting in the friction pair being unable to be effectively lubricated, the compressor power consumption increases, the compression efficiency decreases, and in severe cases, even functional failures may occur.

[0034] The compressor for electric vehicles is a positive displacement compressor with high efficiency, low noise and smooth operation. As the third-generation on-board compressor, it is widely used in automotive air-conditioning systems.
[0035] In recent years, with the development of new energy vehicles, the application scope has been continuously expanded, and the requirements for harsh working conditions have been gradually improved. Under the industry development trend, the performance, noise, vibration and durability of air-conditioning compressors in automobiles have been further improved. Among them, during the use of the compressor, it is necessary to provide oil to lubricate the friction pairs in the compressor to reduce the noise generated when the friction pairs are working, and reduce the performance loss caused by friction power. In the prior art, after the exhaust and oil are separated through the oil separation pipe in the exhaust cover, the oil enters the oil storage tank through the oil return hole of the exhaust cover. The oil in the oil storage tank finally returns to the oil return channel of the compressor through the throttling oil return mechanism, thereby lubricating the friction pairs in the compressor.
[0036] However, in actual use, since the throttling oil return mechanism is directly opposite to the oil return hole, the oil-gas mixed fluid after being diverted by the oil distribution pipe will flush the oil in the oil reservoir due to high speed and high pressure. The oil in the oil reservoir will churn due to the impact, resulting in the through hole connecting the oil reservoir and the throttling oil return mechanism not being completely immersed in the oil. The refrigerant leaks directly from the throttling oil return mechanism to the suction side of the compressor. The refrigerant leaks, the volumetric efficiency decreases, and the cooling capacity of the compressor decreases. In addition, when the refrigerant leaks through the throttling oil return mechanism, it occupies the fluid conveying space of the throttling oil return mechanism, and the oil conveyed to the return oil channel through the throttling oil return mechanism is reduced. The churning of the oil will also cause the refrigerant to be mixed and dissolved in the oil again, and the proportion of oil in the oil reservoir will decrease, thereby further reducing the proportion of oil in the return oil, resulting in the friction pair being unable to be effectively lubricated, the compressor power consumption increases, the compression efficiency decreases, and in severe cases, even functional failures may occur.
[0037] In order to solve the above technical problems, the present application provides a compressor, referring to Figures 1 to 3 As shown, the compressor includes a compression mechanism 10, an exhaust cover 20, an oil separation mechanism 30 and a throttling oil return mechanism 40. The compression mechanism 10 is used to compress low-temperature and low-pressure gas into high-temperature and high-pressure refrigerant gas, the exhaust cover 20 is used to seal the compression mechanism 10 and discharge the high-temperature and high-pressure refrigerant gas, the oil separation mechanism 30 is provided on the exhaust cover 20 to separate the oil in the high-temperature and high-pressure refrigerant gas, and the throttling oil return mechanism 40 is used to control the oil to flow into the compression mechanism 10.
[0038] In some embodiments, reference Figure 1 and Figure 2 As shown, the exhaust cover 20 is arranged on the compression mechanism 10, and the exhaust cover 20 forms an oil storage tank 21. The oil storage tank 21 is provided with ribs 211 to separate and form a first oil storage tank 212 and a second oil storage tank 213. One side of the rib 211 is connected to a side wall of the oil storage tank 21, and the other side of the rib 211 extends to the other side wall of the oil storage tank 21 and is spaced from the other side wall to form a connecting hole 214. The connecting hole 214 connects the first oil storage tank 212 and the second oil storage tank 213; the oil separation mechanism 30 is arranged on the exhaust cover 20, and the oil separation mechanism 30 is connected to the first oil storage tank 212; the throttling oil return mechanism 40 is arranged on the second oil storage tank 213, and the throttling oil return mechanism 40 is connected to the compression mechanism 10.
[0039] In this embodiment, the oil discharged from the oil separation mechanism 30 enters the first oil reservoir 212, and then flows into the second oil reservoir 213 through the connecting hole 214. Since the oil flows from the oil separation mechanism 30 to the first oil reservoir 212 by gravity, the oil entering the first oil reservoir 212 flows in the direction against gravity under the isolation effect of the ribs 211, and then enters the second oil reservoir 213 through the connecting hole 214, and then enters the throttling oil return mechanism 40 through the second oil reservoir 213. In this way, the outflow pressure and outflow speed of the oil can be effectively reduced. In this way, the flow rate and pressure of the oil discharged from the first oil storage tank 212 are reduced, and the impact force of the oil on the existing oil in the second oil storage tank 213 when the oil is discharged is reduced, so as to ensure that the oil in the second oil storage tank 213 remains stable, and ensure that the oil in the second oil storage tank 213 does not churn due to the entry of oil. The effective oil storage volume and oil storage amount of the oil storage tank 21 are increased, and the oil in the second oil storage tank 213 remains stable. It can ensure that the throttling oil return mechanism 40 is always immersed in oil, and the refrigerant is prevented from leaking into the compression chamber 13 through the throttling oil return mechanism 40, so as to ensure that the compression mechanism 10 has sufficient oil return and the friction pair of the compressor is effectively lubricated, thereby improving the compression efficiency of the compressor. In addition, the structure of the oil storage tank 21 is in an "inverted U" shape under the isolation of the ribs 211. The "inverted U" shaped oil storage tank 21 can effectively avoid gas blowby, reduce the leakage of high-temperature and high-pressure gas in the oil separation mechanism 30 into the low-pressure cavity, effectively improve the volumetric efficiency of the compressor and thus increase the cooling capacity.
[0040] In some embodiments, reference Figure 1 and Figure 2 As shown, the first oil reservoir 212 and the second oil reservoir 213 store oil, and the oil level is lower than or equal to the height of the rib 211, and the throttling oil return mechanism 40 is in the oil. The first oil reservoir 212 receives the oil separated by the oil separation mechanism 30, and flows to the second oil reservoir 213 through the connecting hole 214, further avoiding blowby, so that the throttling oil return mechanism 40 is fully immersed in the oil. After throttling by the throttling oil return mechanism 40, the oil enters the fixed scroll 11.
[0041] In some embodiments, reference Figure 1 and Figure 2 As shown, the oil separation mechanism 30 includes an oil separation pipe 31 and an oil accumulation chamber 32 formed in the exhaust cover 20, the oil separation pipe 31 is arranged in the oil accumulation chamber 32, and the oil accumulation chamber 32 is connected to the first oil storage tank 212. The oil separation pipe 31 is used to separate the high-temperature and high-pressure refrigerant from the refrigeration oil mixture, and the oil accumulation chamber 32 is connected to the first oil storage tank 212 to accumulate the separated oil and then flow it into the first oil storage tank 212. In this embodiment, the oil accumulation chamber 32 can also play the role of the oil storage tank 21. When there is too much oil in the oil storage tank 21, the oil accumulation chamber 32 can store part of the oil.
[0042] In some embodiments, the exhaust cover 20 is formed with an oil return hole 22, and the two sides of the oil return hole 22 are connected to the oil accumulation chamber 32 and the first oil reservoir 212. In order to prevent the high-pressure gas from impacting the oil in the oil reservoir 21, a partition wall is provided between the oil accumulation chamber 32 and the oil reservoir 21, and the oil return hole 22 is provided on the partition wall, so as to reduce the impact of the high-pressure gas while maintaining the connection.
[0043] In some embodiments, reference Figure 3 As shown, the compression mechanism 10 includes a fixed scroll 11 and a movable scroll 12. The fixed scroll 11 and the movable scroll 12 cooperate with each other to form a compression chamber 13. The fixed scroll 11 is provided with an air flow hole 111. One side of the air flow hole 111 is connected to the throttling oil return mechanism 40, and the other side of the air flow hole 111 is connected to the compression chamber 13. The oil enters the compression chamber 13 through the throttling oil return mechanism 40 and the air flow hole 111. The movable scroll 12 moves around the fixed scroll 11, and a closed space is formed between the fixed scroll 11 and the movable scroll 12 as the compression chamber 13. The volume of the compression chamber 13 gradually decreases, thereby realizing the compression process of the refrigerant gas. Specifically, the low-temperature and low-pressure refrigerant gas changes in volume through the compression chamber 13, and is compressed into a high-temperature and high-pressure refrigerant gas and discharged.
[0044] In some embodiments, reference Figure 1 and Figure 3 As shown, the exhaust cover 20 is formed with an air inlet 23, a volume chamber 24 is formed between the exhaust cover 20 and the fixed scroll 11, and the compression chamber 13, the volume chamber 24, the air inlet 23 and the oil accumulation chamber 32 are sequentially connected, so that the high-temperature and high-pressure gas can be further pressurized in the volume chamber 24 and then circulated into the oil accumulation chamber 32.
[0045] In some embodiments, in combination Figure 3 and Figure 4 As shown, the compressor includes a frame 50 and a bearing 60, the bearing 60 is arranged on the bearing 60 hole 51 of the frame 50, and the frame 50 forms a guide groove 52 on the peripheral side of the bearing 60 hole 51, the guide groove 52 connects the bearing 60 hole 51 and the air flow hole 111, and part of the oil enters the bearing 60 hole 51 through the throttling oil return mechanism 40, the air flow hole 111, and the guide groove 52, which can cool and lubricate the bearing 60. Specifically, the bearing 60 hole 51 is arranged along the central axis, the bearing 60 and the bearing 60 hole 51 are tightly matched and coaxially matched, and the guide groove 52 is arc-shaped along the peripheral side of the bearing 60 hole 51. At least one circulation channel can be set between the guide groove 52 and the bearing 60 hole 51, which is used to circulate the oil in the guide groove 52 to the bearing 60 hole 51, so as to achieve better lubrication and cooling effects on the bearing 60 hole 51.
[0046] In some embodiments, in combination Figure 3 and Figure 5As shown, the compressor further includes a wear-resistant sheet 70, which is disposed between the movable scroll 12 and the frame 50. The wear-resistant sheet 70 is formed with a first hole 71 and a second hole 72. The first hole 71 is connected to the guide groove 52 and the air flow hole 111, and the second hole 72 is connected to the guide groove 52 and the compression chamber 13. Part of the oil enters the compression chamber 13 through the first hole 71, the guide groove 52 and the second hole 72. The first hole 71 is located outside the second hole 72 in the radial direction, and a plurality of first holes 71 can be provided on the circumferential side. The wear-resistant sheet 70 is disposed on the frame 50, and a positioning pin can be provided on the frame 50. A positioning hole is provided on the wear-resistant sheet 70, and the positioning pin is inserted into the positioning hole so that the wear-resistant sheet 70 can be disposed on the frame 50 to keep the wear-resistant sheet 70 and the frame 50 relatively still.
[0047] In some embodiments, reference Figure 6 As shown, the fixed scroll 11 is provided with an oil guide groove 53, and the oil guide groove 53 is connected to the air flow hole 111 and extends in the circumferential direction of the fixed scroll 11. The oil guide groove 53 connects the air flow hole 111 and the compression chamber 13. The oil guide groove 53 extending in the circumferential direction can increase the area covered by the oil in the compression chamber 13, so that the oil is more easily guided to the compression chamber 13 and the bearing 60.
[0048] In some embodiments, the compression chamber 13 further includes an air intake port disposed between the fixed scroll 11 and the movable scroll 12 , and the oil recovered from the oil return mechanism enters the compression chamber 13 through the air intake port.
[0049] In some embodiments, reference Figure 7 As shown, the static vortex 11 is provided with an exhaust valve, which is arranged on the exhaust port of the static vortex 11, and the compressed high-temperature and high-pressure refrigerant gas enters the oil separation mechanism 30 through the exhaust port. The throttling oil return mechanism 40 includes a filter screen, which is a hollow structure and has a throttle valve inside, wherein part of the filter screen is exposed outside the static vortex 11, thereby extending into the second oil storage tank 213.
[0050] In some embodiments, the throttling oil return mechanism 40 can be inserted obliquely into the interior of the transverse scroll, or can be directly inserted into the interior of the transverse scroll. Here, it is mainly inserted obliquely into the fixed scroll 11 (such as Figure 8 shown).
[0051] The present application also provides a vehicle, including the above-mentioned compressor, wherein the movable scroll 12 moves around the fixed scroll 11, and a closed space is gradually formed between the fixed scroll 11 and the movable scroll 12 as a compression chamber 13, and the volume of the compression chamber 13 gradually decreases, thereby realizing the compression process of the refrigerant gas. The oil discharged from the oil separation mechanism 30 enters the first oil storage tank 212, and then flows into the second oil storage tank 213 through the connecting hole 214. Since the oil flows from the oil separation mechanism 30 to the first oil storage tank 212 by gravity, the oil entering the first oil storage tank 212 flows in the direction against gravity under the isolation effect of the ribs 211, and then enters the second oil storage tank 213 through the connecting hole 214, and then enters the throttling oil return mechanism 40 through the second oil storage tank 213. In this way, the outflow pressure and outflow speed of the oil can be effectively reduced, and the impact force of the oil on the existing oil in the second oil storage tank 213 when the oil is discharged is reduced, thereby ensuring that the oil in the second oil storage tank 213 remains stable, ensuring sufficient oil return to the compression mechanism 10, and ensuring that the friction pair of the compressor is effectively lubricated, thereby improving the compression efficiency of the compressor.
