[0042] This invention provides a baffle assembly, a rotor assembly, and a compressor that reduce compressor oil discharge rate, reduce rotor wind resistance loss, effectively improve the heat exchange efficiency of the air conditioning system, and thus improve the energy efficiency of the compressor and the air conditioning system.

[0043] The following is combined Figures 1-10 The technical solution provided by this invention will be described in more detail below.

[0044] The present invention provides a baffle assembly 100, including a drive structure 110 and a baffle structure 120. The baffle structure 120 is oscillatingly disposed on a rotor structure 200. The drive structure 110 is connected to the baffle structure 120 and is used to drive the baffle structure 120 to oscillate in order to adjust the opening size of the flow hole 210 on the rotor structure 200.

[0045] The baffle assembly 100 provided by the present invention includes a drive structure 110 and a baffle structure 120. The baffle structure 120 is rotatably mounted on the rotor structure 200. The drive structure 110 is used to drive the baffle structure 120 to swing, thereby adjusting the opening size of the flow hole 210 on the rotor structure 200, adjusting the flow area of ​​the flow hole 210, and thus controlling the flow rate, reducing the compressor oil discharge rate, reducing rotor wind resistance loss, effectively improving the heat exchange efficiency of the air conditioning system, and thus improving the energy efficiency of the compressor and the air conditioning system.

[0046] It is understood that the baffle structure 120 is oscillatingly mounted on the rotor structure 200, and the drive structure 110 is connected to the baffle structure 120. The drive structure 110 can drive the baffle structure 120 to oscillate, so that the baffle structure 120 partially or completely covers the flow hole 210, thereby adjusting the flow area of ​​the flow hole 210 to reduce the compressor oil discharge rate, reduce rotor wind resistance loss, effectively improve the heat exchange efficiency of the air conditioning system, and thus improve the energy efficiency of the compressor and the air conditioning system.

[0047] In some embodiments of the present invention, the baffle structure 120 includes two sets of baffles 121, both sets of baffles 121 are oscillatingly disposed on the rotor structure 200, and a linkage structure 122 is provided between the two sets of baffles 121.

[0048] The drive structure 110 is connected to any of the baffles 121 and can drive the two sets of baffles 121 to move closer to or further away from each other in order to adjust the opening size of the flow holes 210 on the rotor structure 200.

[0049] In some embodiments of the present invention described above, the baffle structure 120 includes two sets of baffles 121, both sets of baffles 121 being oscillatingly mounted on the rotor structure 200. A linkage structure 122 is provided between the two sets of baffles 121, ensuring that the two sets of baffles 121 can swing together when either baffle 121 swings, thereby moving towards or away from each other. The drive structure 110 is connected to either baffle 121, thereby adjusting the opening size of the flow passage 210 by the mutual movement of the two sets of baffles 121. The flow area of ​​the flow passage 210 is adjusted by the mutual movement of the two sets of baffles 121, thereby controlling the flow rate, reducing the compressor oil discharge rate, reducing rotor wind resistance loss, effectively improving the heat exchange efficiency of the air conditioning system, and thus improving the energy efficiency of the compressor and the air conditioning system.

[0050] It should be noted that by setting two sets of baffles 121, the two sets of baffles 121 can move closer to or further away from each other, and the swing angle of a single baffle 121 can be greatly reduced, thus making it easier to adjust.

[0051] In some embodiments of the present invention, each set of baffles 121 is provided with a swing rod 123 between it and the rotor structure 200. The first end of the swing rod 123 is rotatably connected to the baffle 121, and the second end of the swing rod 123 is rotatably connected to the rotor structure 200. The linkage structure 122 is provided between the swing rods 123 on the two baffles 121.

[0052] In some embodiments of the present invention described above, the baffle plate 121 is connected to the rotor structure 200 via a swing rod 123. The first end of the swing rod 123 is rotatably connected to the baffle plate 121, and the second end of the swing rod 123 is rotatably connected to the rotor structure 200. The linkage structure 122 is disposed between the swing rods 123 on the two baffle plates 121. The linkage structure 122 drives the two swing rods 123 to swing synchronously, and the swing directions of the two swing rods 123 are opposite, thereby enabling the two sets of baffle plates 121 to move closer to or further away from each other.

[0053] Optionally, the swing rod 123 is rotatably connected to the rotor structure 200 by a fixed rivet, and the swing rod 123 is rotatably connected to the baffle plate 121 by a sliding bolt.

[0054] In some embodiments of the present invention, the linkage structure 122 includes a first tooth structure 1221 and a second tooth structure 1222, the first tooth structure 1221 and the second tooth structure 1222 are respectively disposed on the two baffles 121, and the first tooth structure 1221 and the second tooth structure 1222 mesh with each other.

[0055] In some embodiments of the present invention described above, the linkage structure 122 includes a first tooth structure 1221 and a second tooth structure 1222. The first tooth structure 1221 and the second tooth structure 1222 mesh with each other. When the driving structure 110 drives any one of the baffles 121 to swing, the other baffle 121 can swing along with the first tooth structure 1221 and the second tooth structure 1222, thereby enabling the two sets of baffles 121 to move closer to or further away from each other to adjust the size of the flow passage 210 and the flow area of ​​the flow passage 210, thereby controlling the flow rate, reducing the compressor oil discharge rate, reducing rotor wind resistance loss, effectively improving the heat exchange efficiency of the air conditioning system, and thus improving the energy efficiency of the compressor and the air conditioning system.

[0056] In some embodiments of the present invention, two sets of swing rods 123 are provided between each set of the baffle plate 121 and the rotor structure 200, and the two sets of swing rods 123 are arranged in parallel.

[0057] In some embodiments of the present invention described above, two sets of swing rods 123 are provided between the baffle plate 121 and the rotor structure 200. The swing rods 123 are arranged in parallel to ensure that the baffle plate 121 and the rotor structure 200 form a parallel four-bar linkage structure, thereby further ensuring the movement accuracy of the baffle plate 121.

[0058] In some embodiments of the present invention, the drive structure 110 includes a pressure-bearing structure, a connecting rod 113 and a drive rod 114, wherein the pressure-bearing structure is slidably disposed on the rotor structure 200 along the radial direction of the rotor structure 200;

[0059] The drive rod 114 is slidably disposed on the rotor structure 200 along the circumference of the rotor structure 200. One end of the drive rod 114 is connected to any of the baffles 121, and the connecting rod 113 is connected between the pressure structure and the other end of the drive rod 114.

[0060] In some embodiments of the present invention described above, the drive structure 110 includes a pressure-bearing structure, a connecting rod 113, and a drive rod 114. The pressure-bearing structure is slidably disposed on the rotor structure 200 radially. The pressure-bearing rod 111 slides radially on the rotor structure 200 due to real-time changes in the suction and discharge pressures within the compressor cavity. The drive rod 114 is slidably disposed on the rotor structure 200 circumferentially. The connecting rod 113 connects the other end of the pressure-bearing structure and the drive rod 114. When the pressure-bearing structure slides, the connecting rod 113 drives the drive rod 114 to slide circumferentially on the rotor structure 200, thereby driving the baffle plate 121 to swing. This adjusts the opening size of the flow passage 210 on the rotor structure 200, adjusts the flow area of ​​the flow passage 210, and thus controls the flow rate, reducing the compressor oil discharge rate, reducing rotor wind resistance loss, effectively improving the heat exchange efficiency of the air conditioning system, and thus improving the energy efficiency of the compressor and the air conditioning system.

[0061] It should be noted that the drive structure 110 can also be implemented using other pneumatic adjustment devices, which can dynamically adjust according to the suction and discharge pressure ratio of the compressor.

[0062] In some embodiments of the present invention, an elastic element 115 is further provided between the drive rod 114 and the rotor structure 200.

[0063] In some embodiments of the present invention described above, an elastic element 115 is provided between the drive rod 114 and the rotor structure 200. The elastic element 115 can drive the drive rod 114 to reset, so as to ensure that the opening size of the flow passage 210 can be changed according to the real-time suction and discharge pressure in the compressor cavity.

[0064] In some specific embodiments of the present invention, the pressure-bearing structure includes a pressure-bearing rod 111 and a force-bearing block 112. The force-bearing block 112 is connected to the pressure-bearing rod 111. The pressure-bearing rod 111 is slidably disposed on the rotor structure 200 radially along the rotor structure 200. The pressure-bearing rod 111 is connected to the connecting rod 113.

[0065] In some specific embodiments of the present invention described above, the pressure-bearing structure includes a pressure-bearing rod 111 and a force-bearing block 112. By setting the force-bearing block 112, the area of ​​the force-bearing block 112 is larger, and the force-bearing block 112 can better and more efficiently follow the real-time changes in the suction and discharge pressure in the compressor cavity, thereby achieving more precise adjustment.

[0066] In some specific embodiments of the present invention, the force-bearing block 112 has an arc-shaped structure, and the force-bearing block 112 and the pressure rod 111 form a Y-shaped structure.

[0067] The present invention also provides a rotor assembly, including a rotor structure 200 and a baffle assembly 100 as described above.

[0068] The present invention also provides a compressor including the rotor assembly described above.

[0069] Example 1:

[0070] The rotor assembly provided by this invention, such as Figures 1-6 As shown, the system includes a rotor structure 200 and a baffle assembly 100. The baffle assembly 100 is disposed on the rotor structure 200. The baffle assembly 100 can adjust the opening size of the flow passage 210 on the rotor structure 200, thereby adjusting the flow area of ​​the flow passage 210, and thus controlling the flow rate, reducing the compressor oil discharge rate, reducing rotor wind resistance loss, effectively improving the heat exchange efficiency of the air conditioning system, and thus improving the energy efficiency of the compressor and the air conditioning system.

[0071] Furthermore, the baffle assembly 100 includes a drive structure 110 and a baffle structure 120. The baffle structure 120 includes two sets of baffles 121. Both sets of baffles 121 can be oscillatingly disposed on the rotor structure 200. A linkage structure 122 is provided between the two sets of baffles 121.

[0072] The drive structure 110 is connected to any of the baffles 121 and can drive the two sets of baffles 121 to move closer to or further away from each other in order to adjust the opening size of the flow holes 210 on the rotor structure 200.

[0073] Furthermore, each set of the baffle plate 121 is provided with a swing rod 123 between it and the rotor structure 200. The first end of the swing rod 123 is rotatably connected to the baffle plate 121, and the second end of the swing rod 123 is rotatably connected to the rotor structure 200. The linkage structure 122 is provided between the swing rods 123 on the two baffle plates 121.

[0074] The linkage structure 122 includes a first tooth structure 1221 and a second tooth structure 1222. The first tooth structure 1221 and the second tooth structure 1222 are respectively disposed on the two baffles 121, and the first tooth structure 1221 and the second tooth structure 1222 mesh with each other.

[0075] Optionally, two sets of swing rods 123 are provided, and the two sets of swing rods 123 are arranged in parallel.

[0076] Specifically, the two sets of baffles 121 are a left baffle dynamic plate 1211 and a right baffle dynamic plate 1212. A transmission link 1233 is provided on the right baffle dynamic plate 1212. The first end of the transmission link 1233 is rotatably connected to the right baffle dynamic plate 1212. The second end of the transmission link 1233 is rotatably connected to the rotor structure 200. The second tooth structure 1222 is provided on the transmission link 1233.

[0077] The left flow-blocking dynamic plate 1211 is provided with a fixed rod 1231 and a reverse balance connecting rod 1232. The fixed rod 1231 and the reverse balance connecting rod 1232 are arranged in parallel, and the first ends of the fixed rod 1231 and the reverse balance connecting rod 1232 are rotatably connected to the left flow-blocking dynamic plate 1211. The second ends of the fixed rod 1231 and the reverse balance connecting rod 1232 are rotatably connected to the rotor structure 200. The first tooth structure 1221 is provided on the reverse balance connecting rod 1232.

[0078] Furthermore, the drive structure 110 includes a pressure-bearing structure, a connecting rod 113, and a drive rod 114. The pressure-bearing structure is slidably disposed on the rotor structure 200 along the radial direction of the rotor structure 200.

[0079] The drive rod 114 is slidably disposed on the rotor structure 200 along the circumference of the rotor structure 200. One end of the drive rod 114 is connected to the right flow-blocking dynamic plate 1212, and the connecting rod 113 is connected between the pressure rod 111 and the other end of the drive rod 114.

[0080] Specifically, the pressure-bearing structure includes a pressure-bearing rod 111 and a force-bearing block 112. The force-bearing block 112 is connected to the pressure-bearing rod 111. The force-bearing block 112 has an arc-shaped structure. The force-bearing block 112 and the pressure-bearing rod 111 form a Y-shaped structure. The pressure-bearing rod 111 is slidably disposed on the rotor structure 200 radially along the rotor structure 200. The pressure-bearing rod 111 is connected to the connecting rod 113.

[0081] More specifically, the pressure rod 111 is slidably mounted on the rotor structure 200 radially via a guide rail and a slider. The drive rod 114 is also slidably mounted on the rotor structure 200 circumferentially via a guide rail and a slider.

[0082] Furthermore, an elastic element 115 is also provided between the drive rod 114 and the rotor structure 200.

[0083] Specifically, one end of the elastic element 115 is connected to the limiting post 116 on the rotor structure 200, and the other end of the elastic element 115 is connected to the drive rod 114.

[0084] Furthermore, all baffle assemblies 100 are made of non-magnetic materials.

[0085] During compressor operation, assume the suction and discharge pressure ratio experienced by the Y-type pressure-bearing structure is... A represents the pressure area of ​​the intake and exhaust gases, and the flow orifice 210 is greatly affected by the exhaust pressure. Since the gas flow friction is much smaller than the exhaust pressure, ideally: the pressure-bearing rod 111 of the Y-shaped pressure-bearing structure is affected by the exhaust pressure and moves radially outward from the center, while the connecting rod 113 experiences the same exhaust pressure as the pressure-bearing structure. Without considering the bending moment generated by the connecting rod 113, the pressure-bearing rod 111 decomposes the exhaust pressure into a force F along the guide rail normal. f With a force F along the tangential direction of the guide rail q And F q Proportional to F 排 .

[0086] Under high pressure ratio conditions, exhaust pressure tangential force F q > The elastic force Kx of the elastic element, where K is the elastic force coefficient of the elastic element and x is the spring deformation distance. L-shaped drive rod 114 at F q Under the action of the force, the flow path slides counterclockwise within the guide rail, thereby causing the left / right dynamic baffles 121 to move a distance L to the left / right respectively. Simultaneously, the elastic element is restricted by the limiting post 116 and is under pressure. Since the frictional force of the guide rail is much less than the exhaust pressure, the displacement distance L of the flow path satisfies... Where m1 is the weight of the dynamic baffle 121, μ is its friction coefficient, and t is the duration of being subjected to exhaust pressure.

[0087] As the exhaust pressure increases, the balance between the connecting rod 113 and the L-shaped drive rod 114 is broken. The pressure rod 111 is subjected to the air pressure inside the compressor cavity and moves radially upward to the guide rail. The connecting rod 113 is pressed down by the Y-shaped pressure structure, pushing the L-shaped drive rod 114 to move counterclockwise on the guide rail. The L-shaped drive rod 114 pushes the right dynamic baffle 121 to open. The transmission connecting rod 1233 also tilts to the right along with the right baffle dynamic plate 1212. The teeth of the transmission connecting rod 1233 and the teeth of the reverse balance connecting rod 1232 change from being engaged to being separated. The teeth of the transmission connecting rod 1233 drive the teeth of the reverse balance connecting rod 1232 to move, thereby causing the reverse balance connecting rod 1232 to tilt to the left. The tilting of the reverse balance connecting rod 1232 simultaneously drives the right dynamic baffle 121 to move to the right, drives the left baffle dynamic plate 1211 to move to the left, and simultaneously pulls the fixed rod 1231 to tilt to the left. At this point, the left and right dynamic baffles 121 separate, exposing the flow passage 210. This increases the rotor flow area, improving airflow uniformity, reducing airflow pressure fluctuations, and mitigating vibration and noise issues. Simultaneously, the exhaust pressure decreases as the flow area increases, effectively reducing compressor operating losses and improving compressor performance.

[0088] During compressor operation, as the discharge pressure decreases, the tangential force F of the discharge pressure decreases. q When the elastic force Kx of the elastic element 115 is released, the released force causes the L-shaped drive rod 114 to move clockwise within the guide rail, thereby pushing the right baffle dynamic plate 1212 towards a closing tendency. The transmission link 1233 also tilts to the left along with the right baffle dynamic plate 1212. The teeth of the transmission link 1233 and the teeth of the reverse balance link 1232 change from separation to engagement. The teeth of the transmission link 1233 drive the teeth of the reverse balance link 1232 to move, causing the reverse balance link 1232 to tilt to the right. This tilting of the reverse balance link 1232 simultaneously causes the right baffle dynamic plate 1212 to move to the left and the left baffle dynamic plate 1211 to move to the right, while also pulling the fixed rod 1231 to tilt to the right. At this time, the left and right dynamic baffle plates 121 tend to close, reducing the rotor flow area, lowering the compressor oil discharge rate, and reducing rotor wind resistance loss. The exhaust pressure increases as the flow area decreases, which can effectively improve the compression capacity and enhance the cooling effect.

[0089] When the exhaust pressure tangential force F q = The elastic force Kx of the elastic element 115, at this time the teeth of the transmission link 1233 and the reverse balance link 1232 are in contact, the left flow-blocking dynamic plate 1211 and the right flow-blocking dynamic plate 1212 overlap, completely blocking the flow passage 210, and the rotor flow passage area is minimized.

[0090] Assume the area S of a single flow orifice 210 is approximately S≈lw, where w is the width of the flow orifice 210 and l is the length of the flow orifice 210. Then the total flow area...

[0091] From the above, it is easy to conclude: The total flow area is directly proportional to the ratio of intake and exhaust pressures, M.

[0092] Optimally, x is affected by the tangential force of the exhaust pressure and the position of the limiting post 116, and x should satisfy...

[0093] Optimally, the flow area can be adjusted based on the compressor's APF (Average Power Flow Rate) ratio. When the APF ratio for high frequencies (greater than 40Hz) exceeds 40%, adjusting drive rod 114 reduces the rotor flow area, optimizes the oil circuit, thereby reducing the compressor's oil discharge rate and improving high-frequency efficiency. When the APF ratio for low frequencies (less than 40Hz) exceeds 40%, adjusting drive rod 114 increases the rotor flow area, effectively reducing air resistance and improving compressor energy efficiency.

[0094] Ideally, the size of the flow area can be adjusted according to the proportion of noise frequency distribution. For compressors with severe low-frequency noise, a larger flow area results in more significant noise reduction; for compressors with high-frequency noise, to balance energy efficiency, the following must be met: n is the nth harmonic. Optimally, to achieve the best noise reduction effect, the flow areas of the symmetrical flow holes 210 should be kept consistent.

[0095] Example 2:

[0096] The difference between Example 2 and Example 1 is as follows: Figures 7-10 As shown, the right flow-blocking dynamic plate 1212 is provided with an adjusting rod 1234 and a transmission connecting rod 1233. The adjusting rod 1234 and the transmission connecting rod 1233 are arranged in parallel, and the first ends of the adjusting rod 1234 and the transmission connecting rod 1233 are rotatably connected to the right flow-blocking dynamic plate 1212. The second ends of the adjusting rod 1234 and the transmission connecting rod 1233 are rotatably connected to the rotor structure 200. The drive structure 110 is connected to the transmission connecting rod 1233.
