Description

Technical Field

[0002] The cooling and lubrication of the refrigerant plays a vital role in the operation of the compressor, and directly affects the reliability and performance of the compressor. The rotating shaft of the motor of the existing compressor is set in the middle of the frame bearing chamber, and the rotating shaft blocks the frame bearing chamber. When the motor rotates rapidly, the motor drives the mixture of gas and coolant, that is, the refrigerant, to disperse around, causing a large amount of refrigerant to be discharged with the gas, and it is difficult to enter the interior of the frame bearing chamber. Therefore, the frame bearing can only rely on a small amount of refrigerant entering the frame bearing chamber for lubrication, and cannot fully lubricate the interior of the frame bearing chamber. This setting increases the friction power inside the compressor, which affects the performance and noise of the compressor. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The compressor and the vehicle provided by the utility model are described in detail below in conjunction with the embodiments.

[0025] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 It is a structural schematic diagram of an embodiment of a compressor of the present application; Figure 2 It is a structural schematic diagram of an embodiment of a rack of the present application; Figure 3 1 is a schematic diagram of a structure of an embodiment of a frame and a shielding member of the present application. In one aspect of the present application, a compressor 100 is provided. In one embodiment, the compressor 100 includes a housing 1, a frame 2 and a shielding member 3. The frame 2 and the shielding member 3 are arranged in the housing 1.

[0026] The frame 2 divides the shell 1 into an air intake chamber 11 and a compression chamber 13. The air intake chamber 11 and the compression chamber 13 are arranged on opposite sides of the frame 2. A mixture of gas and coolant, i.e., refrigerant, enters the air intake chamber 11 inside the shell 1. The refrigerant in the air intake chamber 11 flows into the compression chamber 13 through the airway hole 25 of the frame 2, and the compression chamber 13 performs air intake compression on the refrigerant. The frame 2 is provided with an airway hole 25 and a bearing chamber 27. The airway hole 25 connects the air intake chamber 11 and the compression chamber 13. The refrigerant in the air intake chamber 11 flows into the compression chamber 13 through the airway hole 25. The bearing chamber 27 is arranged inside the frame 2. The airway hole 25 and the bearing chamber 27 are arranged at intervals. The airway hole 25 and the bearing chamber 27 cannot be connected.

[0027] In order to cool and lubricate the bearing chamber 27, the frame 2 is provided with a flow groove 291 connecting the airway hole 25 and the bearing chamber 27 on the surface of the first side 29 facing the compression chamber 13. The first side 29 of the frame 2 is recessed toward the suction chamber 11 to form the flow groove 291. The refrigerant in the airway hole 25 can flow into the bearing chamber 27 through the flow groove 291 to cool and lubricate the bearing chamber 27.

[0028] A shielding member 3 is provided on the first side 29 of the frame 2. The orthographic projection of the shielding member 3 on the first side 29 covers part of the airway hole 25. The shielding member 3 can be provided to actively interfere with and divert the refrigerant in the airway hole 25. The shielding member 3 changes the movement direction of the refrigerant in part of the airway hole 25, so that the refrigerant in part of the airway hole 25 flows into the circulation groove 291, and enters the bearing chamber 27 through the circulation groove 291 to cool and lubricate the bearing chamber 27. For example, the refrigerant in the airway hole 25 moves axially, and the refrigerant in part of the airway hole 25 impacts the shielding member 3, and the movement direction of the refrigerant in part of the airway hole 25 changes from axial to radial, so that the refrigerant in part of the airway hole 25 enters the circulation groove 291, and then enters the bearing chamber 27 to cool and lubricate the bearing chamber 27.

[0029] When the compressor 100 is running, the mixture of gas and coolant, i.e., the refrigerant, enters the suction chamber 11 inside the housing 1. When the refrigerant flows from the suction chamber 11 to the compression chamber 13 through the airway hole 25, the refrigerant encounters the obstruction of the shielding member 3 and changes the flow direction, thereby flowing back into the circulation groove 291, and enters the bearing chamber 27 through the gathering and guidance of the circulation groove 291 to cool and lubricate the bearing chamber 27. And because the shielding member 3 does not completely block the airway hole 25, some refrigerant directly enters the compression chamber 13 through the airway hole 25, thereby ensuring the vortex suction volume of the compressor 100.

[0030] In the above manner, the shielding member 3 and the flow groove 291 are provided to actively interfere with and divert the refrigerant in the airway hole 25, thereby increasing the refrigerant flow to the bearing chamber 27, thereby effectively improving the lubrication effect of the refrigerant on the bearing chamber 27, so that the bearing chamber 27 is always kept in a good lubrication state, reducing the friction and vibration of the bearing chamber 27 during operation, thereby reducing the impact of the friction in the bearing chamber 27 on the compressor 100, improving the performance of the compressor 100, and enhancing the reliability of the compressor 100 and extending the service life of the compressor 100. And because the shielding member 3 does not completely block the airway hole 25, some refrigerant directly enters the compression chamber 13 through the airway hole 25, ensuring the vortex suction volume of the compressor 100.

[0031] The cross-sectional shape, depth, width, and number of the flow slots 291 can be set according to actual conditions and are not limited here. The cross-sectional shape of the flow slots 291 includes but is not limited to circular, trapezoidal, rectangular, semicircular, polygonal, etc. The number of the flow slots 291 includes but is not limited to 1, 2, 3, 4, 5, 6, 8, 13, etc.

[0032] The way in which the refrigerant enters the airway hole 25 can be set according to actual conditions and is not limited here. In one specific embodiment, the air suction chamber 11 is directly connected to the airway hole 25. The refrigerant in the air suction chamber 11 directly enters the airway hole 25. In another specific embodiment, an airway is provided on the inner wall of the shell 1. The airway is connected to the corresponding airway hole 25. The refrigerant entering the air suction chamber 11 enters the airway hole 25 through the airway.

[0033] See also Figure 2 , Figure 4 and Figure 5 , Figure 4 is a cross-sectional schematic diagram of an embodiment of a compressor of the present application; Figure 5It is a partial cross-sectional schematic diagram of an embodiment of the compressor of the present application. In one embodiment, a guide surface 293 is formed at one end of each circulation groove 291 connected to the corresponding airway hole 25. The function of the guide surface 293 is to facilitate guiding the refrigerant blocked from the backflow on the shielding member 3 into the circulation groove 291. The guide surface 293 can reduce the resistance to the flow of the refrigerant, increase the circulation speed of the refrigerant, and thereby improve the lubrication effect of the refrigerant on the bearing chamber 27, so that the bearing chamber 27 always maintains a good lubrication state. In some specific embodiments, the guide surface 293 can be an arcuate surface or an inclined surface, that is, the hole wall of the airway hole 25 connecting the circulation groove 291 is an arcuate surface or an inclined surface, so that the connection between the airway hole 25 and the circulation groove 291 becomes smooth and not steep, thereby reducing the resistance to the flow of the refrigerant.

[0034] In one embodiment, the depth of each flow groove 291 decreases along the direction from the corresponding airway hole 25 to the bearing chamber 27. In other words, the depth of the flow groove 291 near the bearing chamber 27 is less than the depth of the flow groove 291 near the corresponding airway hole 25. This arrangement helps the refrigerant to quickly pass through the flow groove 291 into the bearing chamber 27, improves the lubrication effect of the refrigerant on the bearing chamber 27, and keeps the bearing chamber 27 in a good lubrication state.

[0035] In another embodiment, an arc-shaped guide surface 293 or an inclined guide surface 293 is formed at one end of each circulation groove 291 connected to the corresponding airway hole 25. At the same time, along the direction from the corresponding airway hole 25 to the bearing chamber 27, the depth of each circulation groove 291 becomes smaller. Such a setting can allow the refrigerant of part of the airway hole 25 to quickly enter the circulation groove 291 after impacting the shielding member 3, and at the same time, the refrigerant in the circulation groove 291 can quickly flow into the bearing chamber 27 to cool and lubricate the bearing chamber 27. Thereby, the resistance of the refrigerant flow can be reduced, the circulation speed of the refrigerant can be increased, the bearing chamber 27 can always maintain a good lubrication state, the friction and vibration of the bearing chamber 27 during operation can be reduced, and the influence of the friction in the bearing chamber 27 on the compressor 100 can be reduced, the performance of the compressor 100 can be improved, the reliability of the compressor 100 can be improved, and the service life of the compressor 100 can be extended.

[0036] When the area of ​​the airway hole 25 covered by the orthographic projection of the shielding member 3 is too small, the refrigerant that changes the direction of movement and enters the circulation groove 291 is insufficient, and the bearing chamber 27 cannot be fully lubricated. When the area of ​​the airway hole 25 covered by the orthographic projection of the shielding member 3 is too large, the refrigerant for cooling and lubricating the bearing chamber 27 is sufficient, but the amount of refrigerant entering the compression chamber 13 through the airway hole 25 will be reduced, resulting in insufficient suction volume in the compression chamber 13, resulting in reduced performance of the compressor 100.

[0037] In order to reasonably control the area of ​​the airway hole 25 covered by the shielding member 3. In one embodiment, the ratio of the area of ​​the airway hole 25 covered by the shielding member 3 to the area of ​​the corresponding airway hole 25 is 3%-7%. The ratio of the area of ​​the airway hole 25 covered by the orthographic projection of the shielding member 3 to the area of ​​the corresponding airway hole 25 includes but is not limited to 3%, 3.5%, 4%, 4.35%, 4.5%, 5%, 5.25%, 5.5%, 6%, 6.15%, 6.4%, 6.6%, 6.8%, 7%, etc.

[0038] By setting the shielding member 3 to cover the area of ​​the airway hole 25, the refrigerant in the airway hole 25 can be reasonably distributed, so that the refrigerant flow entering the circulation groove 291 can fully lubricate the bearing chamber 27. At the same time, the refrigerant flow entering the compression chamber 13 can also ensure the vortex suction volume of the compressor 100, thereby improving the reliability of the operation of the compressor 100.

[0039] In one embodiment, the shielding member 3 is a metal wear-resistant sheet. The material of the shielding member 3 includes but is not limited to gold, silver, copper, iron, steel, tin, etc. The thickness of the metal wear-resistant sheet is 0.2mm-0.6mm. The thickness of the metal wear-resistant sheet includes but is not limited to 0.2mm, 0.21mm, 0.235mm, 0.25mm, 0.27mm, 0.283mm, 0.3mm, 0.315mm, 0.33mm, 0.35mm, 0.37mm, 0.381mm, 0.4mm, 0.45mm, 0.475mm, 0.5mm, 0.525mm, 0.55mm, 0.573mm, 0.58mm, 0.6mm, etc.

[0040] Setting the shielding member 3 as a metal wear-resistant sheet can reduce the noise generated by the refrigerant in the airway hole 25 impacting the shielding member 3, reduce the possibility of deformation of the shielding member 3, further reduce the noise generated when the compressor 100 is working, and improve the reliability of the compressor 100.

[0041] In one embodiment, the shielding member 3 is disposed on the first side 29, and the shielding member 3 covers the circulation groove 291 and forms a refrigerant channel 5 together with the circulation groove 291. The refrigerant channel 5 is connected to the airway hole 25. The refrigerant in the airway hole 25 flows into the bearing chamber 27 through the refrigerant channel 5, and the refrigerant cools and lubricates the bearing chamber 27.

[0042] By providing the refrigerant channel 5, the refrigerant can be effectively guided when circulating in the circulation groove 291, reducing the possibility of interference of the refrigerant during the circulation process. At the same time, the refrigerant channel 5 is connected with the airway hole 25 so that the refrigerant can smoothly flow from the airway hole 25 into the refrigerant channel 5, thereby improving the circulation efficiency of the refrigerant, helping the refrigerant to cool and lubricate the bearing chamber 27, thereby improving the reliability of the compressor 100 and extending the service life of the compressor 100.

[0043] In one embodiment, the flow grooves 291 and the air passage holes 25 are evenly distributed around the bearing chamber 27 , and the flow grooves 291 extend radially on the first side 29 .

[0044] The evenly distributed flow grooves 291 and the airway holes 25 can make the flow of the refrigerant more even, so that the refrigerant can be more effectively transported to the bearing chamber 27, and the refrigerant can cool and lubricate the bearing chamber 27 more effectively, reducing local overheating or wear in the bearing chamber 27. At the same time, the evenly distributed flow grooves 291 and the airway holes 25 can disperse the load, reduce stress concentration, and improve the stability and reliability of the frame 2. The performance of the compressor 100 is further improved, the reliability of the compressor 100 is enhanced, and the service life of the compressor 100 is extended.

[0045] In a specific embodiment, six flow grooves 291 may be provided on the first side 29 of the frame 2 , the six flow grooves 291 and the corresponding airway holes 25 are evenly and symmetrically distributed around the bearing chamber 27 , and the six flow grooves 291 extend radially on the first side 29 .

[0046] In one embodiment, the width of each flow slot 291 gradually decreases along the direction from the corresponding air passage hole 25 to the bearing chamber 27. This arrangement helps to improve the flow of the refrigerant in the flow slot 291, increase the flow rate of the refrigerant, and reduce energy loss. In turn, the refrigerant can fully lubricate the bearing chamber 27, thereby improving the performance and reliability of the compressor 100.

[0047] In one embodiment, the compressor 100 further includes a motor 6 and a compression assembly 7. The motor 6 is disposed in the suction chamber 11. The compression assembly 7 is disposed in the compression chamber 13. That is, the frame 2 is disposed between the motor 6 and the compression assembly 7. The bottom wall of the bearing chamber 27 is also provided with a mounting hole 273 that penetrates the suction chamber 11 and the compression chamber 13. The motor 6 includes a motor shaft 61. The motor shaft 61 passes through the mounting hole 273 and is connected to the compression assembly 7. When the motor 6 is running, the refrigerant entering the suction chamber 11 flows into the compression assembly 7 in the compression chamber 13 through the airway hole 25, and at the same time, the motor shaft 61 drives the compression assembly 7 to operate, and the compression assembly 7 performs suction compression on the refrigerant.

[0048] A bearing 271 is also provided in the bearing chamber 27. The bearing 271 is sleeved on the motor shaft 61. The refrigerant entering the bearing chamber 27 can cool and lubricate the motor shaft 61 while cooling and lubricating the bearing 271.

[0049] The motor 6 and the compression assembly 7 are respectively arranged in the suction chamber 11 and the compression chamber 13 to reduce the influence of the temperature of the motor 6 on the compression performance of the compression assembly 7. At the same time, the mounting hole 273 is arranged so that the motor shaft 61 is connected to the compression assembly 7, so that the compressor 100 has a compact structure and is easy to assemble. The bearing 271 is mounted on the motor shaft 61, and the bearing 271 can support the motor shaft 61, which is beneficial to the stability of the motor shaft 61. This helps to improve the stability and reliability of the compressor 100.

[0050] In a specific embodiment, other parts are also arranged in the bearing chamber 27, such as the motor shaft 61, the eccentric pin 9, the swing balance block 8, etc. The refrigerant entering the bearing chamber 27 can cool and lubricate the bearing 271 and other parts in the bearing chamber 27 at the same time.

[0051] The connection mode between the motor shaft 61 and the compression assembly 7 can be set according to actual conditions and is not limited here. In one specific embodiment, the motor shaft 61 is directly connected to the compression assembly 7. When the motor 6 runs, the motor shaft 61 rotates to drive the compression assembly 7 to run. In another specific embodiment, a swing balance block 8 is set between the motor shaft 61 and the compression assembly 7, and an eccentric pin 9 is set on the side of the motor shaft 61 close to the compression assembly 7. When the motor 6 runs, the motor shaft 61 rotates, and the eccentric pin 9 drives the swing balance block 8 to rotate, thereby driving the compression assembly 7 to run. The provision of the eccentric pin 9 and the swing balance block 8 can make the compressor 100 run stably, reduce the vibration of the compressor 100, and improve the reliability of the compressor 100.

[0052] In one embodiment, the compression assembly 7 includes an orbiting scroll 71 and a fixed scroll 73 that mesh with each other. The orbiting scroll 71 is fixedly connected to the motor shaft 61. The rotation of the motor shaft 61 drives the orbiting scroll 71 to rotate. The fixed scroll 73 is fixedly connected to the frame 2. The orbiting scroll 71 is arranged in the fixed scroll 73. The shielding member 3 is located between the first side 29 and the orbiting scroll 71, which can reduce the direct contact between the frame 2 and the orbiting scroll 71, reduce the wear of the frame 2, and thus reduce the noise caused by the wear.

[0053] A cavity is provided between the movable scroll 71 and the fixed scroll 73, and the cavity is connected to the airway hole 25 and the compression chamber 13. The shell 1 is provided with an air inlet (not shown) and an exhaust port (not shown). The air inlet is connected to the suction chamber 11, and the exhaust port is connected to the compression chamber 13. A static disk exhaust port (not shown) is provided on the fixed scroll 73. The static disk exhaust port is connected to the exhaust port of the shell 1. The refrigerant compressed by the compression assembly 7 is discharged into the shell 1 through the static disk exhaust port, and finally discharged from the exhaust port of the shell 1.

[0054] When the compressor 100 is running, a mixture of gas and coolant, i.e., refrigerant, enters the suction chamber 11 from the air inlet of the housing 1. When the refrigerant flows from the suction chamber 11 to the compression chamber 13 through the airway hole 25, the refrigerant encounters the obstruction of the shielding member 3 and changes the flow direction, thereby flowing back into the circulation groove 291, and enters the bearing chamber 27 through the gathering and guidance of the circulation groove 291 to cool and lubricate the bearing chamber 27. Moreover, since the shielding member 3 does not completely block the airway hole 25, part of the refrigerant directly enters the compression chamber 13 through the airway hole 25. The refrigerant in the compression chamber 13 enters the cavity between the movable scroll 71 and the fixed scroll 73. The motor shaft 61 drives the movable scroll 71 to rotate, and the movable scroll 71 rotates to inhale and compress the refrigerant in the cavity, thereby ensuring the vortex suction volume of the compressor 100. The compressed refrigerant is discharged into the housing 1 through the fixed disk exhaust port, and finally discharged from the exhaust port of the housing 1.

[0055] By setting the shielding member 3 between the first side 29 and the movable scroll 71, the direct contact between the frame 2 and the movable scroll 71 can be reduced, and the refrigerant in the airway hole 25 can be reasonably distributed, which can not only reduce the wear of the frame 2, but also allow the refrigerant in part of the airway hole 25 to enter the bearing chamber 27 through the circulation groove 291, and cool and lubricate the bearing 271, the motor shaft 61 and other parts in the bearing chamber 27. The movable scroll 71 and the fixed scroll 73 are arranged to mesh with each other, and the relative position stability of the two is ensured, while improving the compression performance and reliability of the compression assembly 7. The air inlet and exhaust port of the refrigerant are arranged on the shell 1 to facilitate the circulation of the refrigerant. Thereby improving the performance of the compressor 100, enhancing the reliability of the compressor 100 and extending the service life of the compressor 100.

[0056] In another aspect of the present application, a vehicle is provided, the vehicle comprising the compressor 100 in any one of the above embodiments. The compressor 100 is disposed in the vehicle.

[0057] When the vehicle is running and the compressor 100 is running, a mixture of gas and coolant, i.e., refrigerant, enters the suction chamber 11 from the air inlet of the housing 1. When the refrigerant flows from the suction chamber 11 to the compression chamber 13 through the airway hole 25, the refrigerant encounters the obstruction of the shielding member 3 and changes the flow direction, thereby flowing back into the circulation groove 291 and entering the bearing chamber 27 through the gathering and guidance of the circulation groove 291 to cool and lubricate the bearing chamber 27. Since the shielding member 3 does not completely block the airway hole 25, part of the refrigerant directly enters the compression chamber 13 through the airway hole 25. The refrigerant in the compression chamber 13 enters the cavity between the movable scroll 71 and the fixed scroll 73. The motor shaft 61 drives the movable scroll 71 to rotate. The movable scroll 71 rotates to inhale and compress the refrigerant in the cavity, thereby ensuring the vortex suction volume of the compressor 100. The compressed refrigerant is discharged into the housing 1 through the fixed disk exhaust port, and finally discharged from the exhaust port of the housing 1.

[0058] Through the above-mentioned method, the bearing chamber 27 of the compressor 100 can have a good lubrication effect, thereby reducing the impact of the friction and noise of the compressor 100 on the vehicle, improving the overall vehicle performance of the vehicle, enhancing the reliability of the vehicle, and extending the service life of the vehicle.
