[0002] At present, the internal rotor shaft assembly of the scroll compressor in the related art is generally not completely fixed. During transportation, the rotor shaft assembly will move up and down. During the movement, the rotor shaft assembly will collide with its adjacent parts. Especially during long-distance transportation, multiple collisions will cause abnormal wear and even failure of the corresponding contact pairs. In addition, impurities left by the collision will also fall onto other contact surfaces, affecting the reliability and performance of the scroll compressor. Utility Model Content

[0003] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of an embodiment of the utility model provides a compressor.

[0005] A second aspect of the embodiments of the present utility model provides an air conditioner.

[0006] In view of this, according to the first aspect of an embodiment of the utility model, a compressor is provided, which includes: a fixed scroll, which is provided with an exhaust port; a movable scroll, which is enclosed with the fixed scroll to form a compression chamber, and the compression chamber is connected to the exhaust port; a rotating shaft assembly, which is connected to the movable scroll; a frame, which is arranged on the side of the movable scroll away from the fixed scroll and is connected to the fixed scroll; a buffer, at least a part of the buffer is arranged between the rotating shaft assembly and the movable scroll along the axial direction of the rotating shaft assembly, and / or at least a part of the buffer is arranged between the frame and the rotating shaft assembly along the axial direction of the rotating shaft assembly.

[0007] The compressor provided by the embodiment of the utility model includes a fixed scroll, a movable scroll, a rotating shaft assembly, a frame and a buffer. Specifically, the fixed scroll and the movable scroll enclose a compression chamber, the compression chamber is connected to the exhaust port on the fixed scroll, and the rotating shaft assembly is connected to the movable scroll. Specifically, driven by the rotating shaft assembly, the movable scroll performs translational rotation relative to the fixed scroll to compress the refrigerant in the compression chamber, and the compressed refrigerant is discharged through the exhaust port when it reaches the exhaust pressure.

[0008] The frame is arranged on a side of the movable scroll away from the fixed scroll, and the frame is connected to the fixed scroll to support the movable scroll.

[0009] It is understandable that during the transportation of the compressor, the shaft assembly cannot be completely fixed and will undergo axial displacement, that is, it will move up and down, causing the shaft assembly to collide with its adjacent components, resulting in wear of the shaft assembly and its adjacent components, reducing the service life of the compressor and affecting the performance of the compressor.

[0010] Along the axial direction of the shaft assembly, at least part of the buffer is arranged between the shaft assembly and the movable scroll. Alternatively, along the axial direction of the shaft assembly, at least part of the buffer is arranged between the shaft assembly and the frame. Alternatively, along the axial direction of the shaft assembly, buffers are arranged between the shaft assembly and the movable scroll, and between the shaft assembly and the frame. The specific arrangement can be made according to actual needs.

[0011] That is, a buffer is arranged on the axial movement path of the shaft assembly, which can play a buffering role during the transportation of the compressor, effectively solving the problem of rigid collision between the shaft assembly and other components due to the axial movement of the shaft assembly, avoiding wear of the shaft assembly and its adjacent components due to collision, especially wear between the shaft assembly and the movable scroll due to rigid collision, thereby extending the service life of the compressor and improving the reliability and performance of the compressor.

[0012] Optionally, the buffer component includes a buffer gasket. It is understandable that the buffer gasket has a small thickness, so that it can play a buffering role during the transportation of the compressor while avoiding the buffer gasket from contacting other components and affecting the normal operation of the compressor.

[0013] In addition, the compressor provided by the above technical solution of the utility model also has the following additional technical features:

[0014] In some technical solutions, optionally, the buffer member includes a flexible member.

[0015] In this technical solution, it can be understood that the flexible part has good impact resistance, so that it can play a good buffering role during the transportation of the compressor, effectively avoiding the problem of rigid collision between the shaft assembly and other components due to axial movement of the shaft assembly, and further avoiding the wear of the shaft assembly and its adjacent components due to collision, thereby extending the service life of the compressor and improving the reliability and performance of the compressor.

[0016] In some technical solutions, optionally, the flexible part includes a polymer part or a metal part.

[0017] In this technical solution, it is defined that the flexible part is a polymer part, or the flexible part is a metal part, which can be set according to actual needs.

[0018] Optionally, the polymer component includes a rubber component or a silicone component.

[0019] Optionally, the metal member comprises copper.

[0020] In some technical schemes, optionally, the shaft assembly includes a driving member, a shaft and a balancing block, wherein the shaft is connected to the driving member and to the movable scroll, the balancing block is arranged on the shaft or the driving member and is located on the side of the frame away from the movable scroll; along the axial direction of the shaft, at least part of the buffer is located between the balancing block and the frame; and / or along the axial direction of the shaft, at least part of the buffer is located between the shaft and the movable scroll.

[0021] In this technical solution, it is defined that the rotating shaft assembly includes a driving member, a rotating shaft and a balancing block. Specifically, the driving member is connected to the rotating shaft, and the balancing block is arranged on the rotating shaft, or the balancing block is arranged on the driving member. Optionally, the driving member includes a rotor and a stator, the stator is arranged on the radial outer side of the rotor, and the rotor is connected to the rotating shaft. Specifically, under the drive of the driving member, the rotating shaft drives the movable scroll to rotate relative to the fixed scroll to compress the refrigerant in the compression chamber. Among them, when the balancing block is arranged on the driving member, the balancing block is connected to the rotor.

[0022] Along the axial direction of the rotating shaft, at least part of the buffer is arranged between the balancing block and the frame. It is understandable that, in the case where the balancing block is arranged on the rotating shaft, when the rotating shaft is axially displaced, the balancing block will be driven to move axially. In the case where the balancing block is arranged on the driving member, since the rotating shaft is connected to the driving member, when the rotating shaft is axially displaced, the balancing block will be driven to move axially.

[0023] By arranging at least part of the buffer between the balancing block and the frame, during the transportation of the compressor, in addition to avoiding the rigid collision between the balancing block and the frame due to the axial movement of the rotating shaft, the rigid collision between the rotating shaft and the movable scroll can also be indirectly avoided, thereby effectively reducing the wear of the rotating shaft assembly and its adjacent components due to collision, and improving the reliability of the compressor.

[0024] Alternatively, along the axial direction of the rotating shaft, at least part of the buffer is arranged between the rotating shaft and the movable scroll. Alternatively, along the axial direction of the rotating shaft, buffers are arranged between the balancing block and the frame, and between the rotating shaft and the movable scroll. The specific arrangement can be made according to actual needs.

[0025] That is, a buffer is arranged on the axial moving path of the shaft assembly, which can play a buffering role during the transportation of the compressor and effectively solve the problem of rigid collision between the shaft assembly and other components due to the axial movement of the shaft assembly.

[0026] In some technical solutions, optionally, when at least part of the buffer is located between the balancing weight and the frame, the buffer is provided on one of the frame and the balancing weight, and has a first gap with the other in the axial direction of the rotating shaft.

[0027] In this technical solution, it is defined that at least part of the buffer is arranged between the balancing block and the frame, specifically, the buffer is arranged on the frame, and along the axial direction of the rotating shaft, there is a first gap between the buffer and the balancing block. Alternatively, the buffer is arranged on the balancing block, and along the axial direction of the rotating shaft, there is a first gap between the buffer and the frame.

[0028] It is understandable that during the operation of the compressor, the rotating shaft drives the movable scroll to perform translational rotation relative to the fixed scroll, and at the same time, the balancing block also rotates relative to the frame. By providing a first gap between the buffer and the frame or the balancing block along the axial direction of the rotating shaft, during the transportation of the compressor, it is possible to avoid rigid collision between the rotating shaft assembly and its adjacent components, and during the operation of the compressor, it is possible to prevent interference between the buffer and the frame or the balancing block, thereby ensuring the normal operation of the compressor and improving the reliability and performance of the compressor.

[0029] In addition, it is worth mentioning that when the buffer is set on the frame, during the operation of the compressor, since the frame is fixed, the installation stability of the buffer can be improved, and the buffer can be prevented from falling off due to the movement of other components during the operation of the compressor, thereby further ensuring the reliability and stability of the compressor operation.

[0030] Optionally, the buffer member can be fixed to the frame or the balancing weight by gluing or welding.

[0033] In some technical solutions, optionally, along the axial direction of the rotating shaft, a height h of the first gap satisfies h≤3 mm.

[0034] In this technical solution, the range of the axial height of the first gap is limited. Specifically, the axial height of the first gap is less than or equal to 3 mm. This can prevent interference between the buffer and the frame or the balancing block during the operation of the compressor, while preventing the axial size of the compressor from being too large due to the gap between the buffer and the frame or the balancing block being too large.

[0035] Optionally, along the axial direction of the rotating shaft, a height of the first gap is less than or equal to 1.8 mm.

[0036] In some technical solutions, optionally, when the buffer is disposed on a frame, the frame is provided with a slot, and a portion of the buffer is disposed in the slot.

[0037] In this technical solution, it is specified that the buffer is set on the frame. Specifically, the frame is provided with a slot, and a part of the buffer is embedded in the slot, so as to achieve reliable fixation of the buffer. During the transportation of the compressor, it can play an effective buffering role to avoid wear of the shaft assembly and its adjacent components due to rigid collision, especially wear between the shaft assembly and the movable scroll due to rigid collision, thereby extending the service life of the compressor and improving the reliability and performance of the compressor.

[0039] In this technical solution, it is defined that the rotating shaft includes a shaft body and an eccentric shaft. Specifically, the balancing block is arranged on the shaft body or the driving member. The eccentric shaft is arranged at one end of the shaft body close to the movable scroll, and the eccentric shaft is connected to the movable scroll. That is to say, under the drive of the driving member, the shaft body drives the movable scroll to perform translational rotation relative to the fixed scroll through the eccentric shaft.

[0040] Along the axial direction of the rotating shaft, at least part of the buffer is arranged between the eccentric shaft and the movable scroll. Alternatively, along the axial direction of the rotating shaft, at least part of the buffer is arranged between the shaft body and the movable scroll. Alternatively, along the axial direction of the rotating shaft, buffers are arranged between the eccentric shaft and the movable scroll, and between the shaft body and the movable scroll. The specific arrangement can be based on actual needs.

[0041] By providing a buffer between the rotating shaft and the movable scroll, during the transportation of the compressor, it is possible to effectively avoid a rigid collision between the rotating shaft assembly and the movable scroll due to axial movement, thereby reducing the wear of the rotating shaft assembly and the movable scroll due to the rigid collision, extending the service life of the compressor, and improving the reliability and performance of the compressor.

[0042] Optionally, the eccentric shaft and the shaft body are an integral structure.

[0043] In some technical schemes, optionally, the movable scroll includes a disk body and a mounting portion, wherein the disk body and the fixed scroll form a compression chamber, and the mounting portion is arranged on the side of the disk body away from the fixed scroll, and the mounting portion is provided with a mounting groove, and at least a portion of the eccentric shaft is inserted into the mounting groove; along the axial direction of the rotating shaft, at least part of the buffer is arranged between a side surface of the eccentric shaft away from the shaft body and a groove wall of the mounting groove, and / or along the axial direction of the rotating shaft, at least part of the buffer is arranged between a side surface of the shaft body facing the movable scroll and the mounting portion.

[0044] In this technical solution, it is defined that the movable scroll includes a disk body and a mounting portion. Specifically, the mounting portion is arranged on the side of the disk body away from the fixed scroll, and the mounting portion is provided with a mounting groove, and at least a part of the eccentric shaft is inserted into the mounting groove to realize the connection between the eccentric shaft and the movable scroll.

[0045] Along the axial direction of the rotating shaft, at least part of the buffer is arranged between a side of the eccentric shaft away from the shaft body and the groove wall of the installation groove, that is, at least part of the buffer is arranged between the top surface of the eccentric shaft and the groove bottom wall of the installation groove.

[0046] Alternatively, along the axial direction of the rotating shaft, at least part of the buffer is arranged between a side surface of the shaft body facing the movable scroll and the mounting portion, that is, at least part of the buffer is arranged between the upper surface of the shaft shoulder and the lower end surface of the mounting portion.

[0047] Alternatively, along the axial direction of the rotating shaft, a buffer is provided between the top surface of the eccentric shaft and the bottom wall of the mounting groove, and between the upper surface of the shaft shoulder of the rotating shaft and the lower end surface of the mounting portion.

[0048] By providing a buffer between the rotating shaft and the movable scroll, during the transportation of the compressor, it is possible to effectively avoid a rigid collision between the rotating shaft assembly and the movable scroll due to axial movement, thereby reducing the wear of the rotating shaft assembly and the movable scroll due to the rigid collision, extending the service life of the compressor, and improving the reliability and performance of the compressor.

[0049] Optionally, the disk body and the mounting portion are an integrated structure.

[0050] In some technical schemes, optionally, when at least part of the buffer is arranged between a side of the eccentric shaft away from the shaft body and a groove wall of the mounting groove, the buffer is arranged on one of the side of the eccentric shaft away from the shaft body and the groove wall of the mounting groove, and has a second gap with the other along the axial direction of the rotating shaft.

Alternatively, the buffer is arranged on the groove wall of the installation groove, and along the axial direction of the rotating shaft, there is a second gap between the buffer and a side surface of the eccentric shaft away from the shaft body.

[0052] It can be understood that during the operation of the compressor, when the rotating shaft drives the movable scroll to rotate linearly relative to the fixed scroll, there will also be relative movement between the rotating shaft and the movable scroll. By forming a second gap between the buffer component and the groove wall of the mounting groove or the side of the eccentric shaft away from the shaft body, during the transportation of the compressor, it is possible to avoid rigid collision between the rotating shaft assembly and the movable scroll. During the operation of the compressor, it is possible to prevent interference between the buffer component and the movable scroll or the rotating shaft, thereby ensuring the normal operation of the compressor and improving the reliability and performance of the compressor.

[0058] In this technical solution, it is defined that at least a portion of the buffer is arranged between a side surface of the shaft body facing the movable scroll and the mounting portion. Specifically, the buffer is arranged on a side surface of the shaft body facing the movable scroll, and along the axial direction of the rotating shaft, a third gap is present between the buffer and an end of the mounting portion facing away from the disk body.

[0059] It can be understood that during the operation of the compressor, when the rotating shaft drives the movable scroll to rotate linearly relative to the fixed scroll, there will also be relative movement between the rotating shaft and the movable scroll. By forming a third gap between the buffer component and the end of the mounting portion that is away from the disk body, during the transportation of the compressor, a rigid collision between the rotating shaft assembly and the movable scroll can be avoided. During the operation of the compressor, interference between the buffer component and the movable scroll can be prevented, thereby ensuring the normal operation of the compressor and improving the reliability and performance of the compressor.

Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0073] Refer to the following Figures 1 to 5 The compressor 100 and the air conditioner provided according to some embodiments of the present invention are described.

[0074] In one embodiment according to the present application, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a compressor 100 is proposed, and the compressor 100 includes: a fixed scroll 110, and the fixed scroll 110 is provided with an exhaust port 111; a movable scroll 120, which is enclosed with the fixed scroll 110 to form a compression chamber 130, and the compression chamber 130 is connected to the exhaust port 111; a rotating shaft assembly 140, which is connected to the movable scroll 120; a frame 150, which is arranged on the side of the movable scroll 120 away from the fixed scroll 110, and is connected to the fixed scroll 110; a buffer 160, along the axial direction of the rotating shaft assembly 140, at least a part of the buffer 160 is arranged between the rotating shaft assembly 140 and the movable scroll 120, and / or along the axial direction of the rotating shaft assembly 140, at least a part of the buffer 160 is arranged between the frame 150 and the rotating shaft assembly 140.

[0075] The compressor 100 provided by the embodiment of the utility model includes a fixed scroll 110, a movable scroll 120, a rotating shaft assembly 140, a frame 150 and a buffer 160. Specifically, the fixed scroll 110 and the movable scroll 120 enclose a compression chamber 130, the compression chamber 130 is communicated with an exhaust port 111 on the fixed scroll 110, and the rotating shaft assembly 140 is connected to the movable scroll 120. Specifically, driven by the rotating shaft assembly 140, the movable scroll 120 performs translational rotation relative to the fixed scroll 110 to compress the refrigerant in the compression chamber 130, and the compressed refrigerant is discharged through the exhaust port 111 when it reaches the exhaust pressure.

[0076] The frame 150 is disposed on a side of the movable scroll 120 away from the fixed scroll 110 , and the frame 150 is connected to the fixed scroll 110 to support the movable scroll 120 .

[0077] It is understandable that during the transportation of the compressor 100, the shaft assembly 140 cannot be completely fixed, which will cause axial displacement, that is, up and down movement, causing the shaft assembly 140 to collide with its adjacent components, causing wear of the shaft assembly 140 and its adjacent components, reducing the service life of the compressor 100 and affecting the performance of the compressor 100.

[0078] Along the axial direction of the shaft assembly 140, at least part of the buffer 160 is disposed between the shaft assembly 140 and the movable scroll 120. Alternatively, along the axial direction of the shaft assembly 140, at least part of the buffer 160 is disposed between the shaft assembly 140 and the frame 150. Alternatively, along the axial direction of the shaft assembly 140, buffers 160 are disposed between the shaft assembly 140 and the movable scroll 120, and between the shaft assembly 140 and the frame 150. The specific configuration can be based on actual needs.

[0079] That is, a buffer member 160 is arranged on the axial movement path of the rotating shaft assembly 140, which can play a buffering role during the transportation of the compressor 100, effectively solving the problem of rigid collision between the rotating shaft assembly 140 and other components due to the axial movement of the rotating shaft assembly 140, avoiding wear of the rotating shaft assembly 140 and its adjacent components due to collision, especially wear between the rotating shaft assembly 140 and the movable scroll 120 due to rigid collision, thereby extending the service life of the compressor 100 and improving the reliability and performance of the compressor 100.

[0080] Optionally, the buffer member 160 includes a buffer gasket. It is understandable that the buffer gasket has a small thickness, so that it can play a buffering role during the transportation of the compressor 100 while avoiding the buffer gasket from contacting other components and affecting the normal operation of the compressor 100.

[0081] In some embodiments, optionally, the buffer member 160 comprises a flexible member.

[0082] In this embodiment, it can be understood that the flexible part has a good impact resistance effect, so that it can play a good buffering role during the transportation of the compressor 100, effectively avoiding the problem of rigid collision between the shaft assembly 140 and other components due to the axial movement of the shaft assembly 140, and further avoiding the wear of the shaft assembly 140 and its adjacent components due to collision, thereby extending the service life of the compressor 100 and improving the reliability and performance of the compressor 100.

[0083] In some embodiments, optionally, the flexible member includes a polymer member or a metal member.

[0084] In this embodiment, the flexible member is limited to a polymer member, or the flexible member is limited to a metal member, which can be specifically set according to actual needs.

[0085] It can be understood that the flexible polymer parts or flexible metal parts have good impact resistance, so that they can play a good buffering role during the transportation of the compressor 100, effectively avoiding the problem of rigid collision between the shaft assembly 140 and other components due to axial movement, and further avoiding the wear of the shaft assembly 140 and its adjacent parts due to collision, thereby extending the service life of the compressor 100 and improving the reliability and performance of the compressor 100.

[0086] Optionally, the polymer component includes a rubber component or a silicone component.

[0087] Optionally, the metal member comprises copper.

[0088] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the shaft assembly 140 includes a driving member 141, a shaft 142 and a balancing block 143, wherein the shaft 142 is connected to the driving member 141 and to the movable scroll 120, and the balancing block 143 is arranged on the shaft 142 or the driving member 141 and is located on the side of the frame 150 away from the movable scroll 120; along the axial direction of the shaft 142, at least part of the buffer 160 is located between the balancing block 143 and the frame 150; and / or along the axial direction of the shaft 142, at least part of the buffer 160 is located between the shaft 142 and the movable scroll 120.

[0089] In this embodiment, it is defined that the rotating shaft assembly 140 includes a driving member 141, a rotating shaft 142 and a balancing block 143.

Optionally, the driving member 141 includes a rotor and a stator, the stator is arranged on the radial outer side of the rotor, and the rotor is connected to the rotating shaft 142. Specifically, under the drive of the driving member 141, the rotating shaft 142 drives the movable scroll 120 to rotate relative to the fixed scroll 110 in a translational manner to compress the refrigerant in the compression chamber 130. Among them, when the balancing block 143 is arranged on the driving member 141, the balancing block 143 is connected to the rotor.

[0090] Along the axial direction of the rotating shaft 142, at least part of the buffer 160 is disposed between the balancing block 143 and the frame 150. It is understandable that, in the case where the balancing block 143 is disposed on the rotating shaft 142, when the rotating shaft 142 is axially displaced, the balancing block 143 is driven to move axially. In the case where the balancing block 143 is disposed on the driving member 141, since the rotating shaft 142 is connected to the driving member 141, when the rotating shaft 142 is axially displaced, the balancing block 143 is driven to move axially.

[0091] By arranging at least part of the buffer member 160 between the balancing block 143 and the frame 150, during the transportation of the compressor 100, in addition to avoiding a rigid collision between the balancing block 143 and the frame 150 due to the axial movement of the rotating shaft 142, a rigid collision between the rotating shaft 142 and the movable scroll 120 can also be indirectly avoided, thereby effectively reducing the wear of the rotating shaft assembly 140 and its adjacent components caused by the collision, thereby improving the reliability of the compressor 100.

[0092] Alternatively, along the axial direction of the rotating shaft 142, at least part of the buffer 160 is disposed between the rotating shaft 142 and the movable scroll 120. Alternatively, along the axial direction of the rotating shaft 142, buffers 160 are disposed between the balancing block 143 and the frame 150, and between the rotating shaft 142 and the movable scroll 120. The specific configuration can be based on actual needs.

[0093] That is, a buffer member 160 is arranged on the axial moving path of the rotating shaft assembly 140 , which can play a buffering role during the transportation of the compressor 100 , and effectively solves the problem of rigid collision between the rotating shaft assembly 140 and other components due to the axial movement.

[0094] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, when at least part of the buffer 160 is located between the balancing block 143 and the frame 150, the buffer 160 is disposed on one of the frame 150 and the balancing block 143, and has a first gap 170 with the other in the axial direction of the rotating shaft 142.

[0095] In this embodiment, it is defined that at least part of the buffer 160 is disposed between the balancing block 143 and the frame 150. Specifically, the buffer 160 is disposed on the frame 150, and along the axial direction of the rotating shaft 142, there is a first gap 170 between the buffer 160 and the balancing block 143. Alternatively, the buffer 160 is disposed on the balancing block 143, and along the axial direction of the rotating shaft 142, there is a first gap 170 between the buffer 160 and the frame 150.

[0096] It is understandable that during the operation of the compressor 100, the rotating shaft 142 drives the movable scroll 120 to perform translational rotation relative to the fixed scroll 110, and at the same time, the balancing block 143 also rotates relative to the frame 150. By providing the buffer 160 and the frame 150 or the balancing block 143 with a first gap 170 along the axial direction of the rotating shaft 142, during the transportation of the compressor 100, it is possible to avoid rigid collision between the rotating shaft assembly 140 and its adjacent components, and during the operation of the compressor 100, it is possible to prevent interference between the buffer 160 and the frame 150 or the balancing block 143, thereby ensuring the normal operation of the compressor 100 and improving the reliability and performance of the compressor 100.

[0097] In addition, it is worth mentioning that when the buffer 160 is set on the frame 150, during the operation of the compressor 100, since the frame 150 is fixed, the installation stability of the buffer 160 can be improved, and the buffer 160 can be prevented from falling off due to the movement of other components during the operation of the compressor 100, thereby further ensuring the reliability and stability of the operation of the compressor 100.

[0098] Optionally, the buffer member 160 may be fixed to the frame 150 or the balancing block 143 by gluing or welding.

[0099] Optionally, the compressor 100 further includes a retaining spring, and the buffer 160 is connected to the frame 150 or the balancing block 143 via the retaining spring.

[0100] Optionally, the frame 150 or the balancing block 143 is provided with a slot 151 , and a portion of the buffer 160 is embedded in the slot 151 .

[0101] like Figure 1 As shown, in some embodiments, optionally, along the axial direction of the rotating shaft 142 , the height h of the first gap 170 satisfies h≤3 mm.

[0102] In this embodiment, the range of values ​​of the axial height of the first gap 170 is limited. Specifically, the axial height of the first gap 170 is less than or equal to 3 mm. Thus, during the operation of the compressor 100, interference between the buffer 160 and the frame 150 or the balancing block 143 can be avoided, and the axial dimension of the compressor 100 can be avoided to be too large due to the gap formed between the buffer 160 and the frame 150 or the balancing block 143 being too large.

[0103] Optionally, along the axial direction of the rotating shaft 142 , a height of the first gap 170 is less than or equal to 1.8 mm.

[0104] like Figure 1 As shown, in some embodiments, optionally, when the buffer 160 is disposed on the frame 150 , the frame 150 is provided with a slot 151 , and a portion of the buffer 160 is disposed in the slot 151 .

[0105] In this embodiment, it is defined that the buffer 160 is arranged on the frame 150. Specifically, the frame 150 is provided with a slot 151, and a portion of the buffer 160 is embedded in the slot 151, so as to realize reliable fixation of the buffer 160. In addition, during the transportation of the compressor 100, it can play an effective buffering role, avoid the wear of the rotating shaft assembly 140 and its adjacent components due to rigid collision, especially the wear between the rotating shaft assembly 140 and the movable scroll 120 due to rigid collision, thereby extending the service life of the compressor 100 and improving the reliability and performance of the compressor 100.

[0106] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the rotating shaft 142 includes a shaft body 144 and an eccentric shaft 145, wherein a balancing block 143 is disposed on the shaft body 144 or the driving member 141, the shaft body 144 passes through the frame 150, and the eccentric shaft 145 is disposed at one end of the shaft body 144 close to the movable scroll 120 and is connected to the movable scroll 120; when at least part of the buffer 160 is located between the rotating shaft 142 and the movable scroll 120, along the axial direction of the rotating shaft 142, at least part of the buffer 160 is disposed between the eccentric shaft 145 and the movable scroll 120, and / or along the axial direction of the rotating shaft 142, at least part of the buffer 160 is disposed between the shaft body 144 and the movable scroll 120.

[0107] In this embodiment, the rotating shaft 142 is defined to include a shaft body 144 and an eccentric shaft 145. Specifically, the balancing block 143 is disposed on the shaft body 144 or the driving member 141. The eccentric shaft 145 is disposed at one end of the shaft body 144 close to the movable scroll 120, and the eccentric shaft 145 is connected to the movable scroll 120. That is, under the drive of the driving member 141, the shaft body 144 drives the movable scroll 120 to perform translational rotation relative to the fixed scroll 110 through the eccentric shaft 145.

[0108] Along the axial direction of the rotating shaft 142, at least part of the buffer 160 is disposed between the eccentric shaft 145 and the movable scroll 120. Alternatively, along the axial direction of the rotating shaft 142, at least part of the buffer 160 is disposed between the shaft body 144 and the movable scroll 120. Alternatively, along the axial direction of the rotating shaft 142, buffers 160 are disposed between the eccentric shaft 145 and the movable scroll 120, and between the shaft body 144 and the movable scroll 120. The specific configuration can be based on actual needs.

[0109] By providing a buffer member 160 between the rotating shaft 142 and the movable scroll 120, during the transportation of the compressor 100, it is possible to effectively avoid a rigid collision between the rotating shaft assembly 140 and the movable scroll 120 due to axial movement, thereby reducing the wear of the rotating shaft assembly 140 and the movable scroll 120 due to the rigid collision, extending the service life of the compressor 100, and improving the reliability and performance of the compressor 100.

[0110] Optionally, the eccentric shaft 145 and the shaft body 144 are an integral structure.

[0112] In this embodiment, it is defined that the movable scroll 120 includes a disk body 121 and a mounting portion 122. Specifically, the mounting portion 122 is arranged on the side of the disk body 121 away from the fixed scroll 110, and the mounting portion 122 is provided with a mounting groove 123, and at least a part of the eccentric shaft 145 is inserted into the mounting groove 123 to achieve the connection between the eccentric shaft 145 and the movable scroll 120.

[0113] Along the axial direction of the rotating shaft 142, at least part of the buffer member 160 is arranged between the side of the eccentric shaft 145 away from the shaft body 144 and the groove wall of the mounting groove 123, that is, at least part of the buffer member 160 is arranged between the top surface of the eccentric shaft 145 and the groove bottom wall of the mounting groove 123.

[0114] Alternatively, along the axial direction of the rotating shaft 142 , at least part of the buffer member 160 is arranged between a side surface of the shaft body 144 facing the movable scroll 120 and the mounting portion 122 , that is, at least part of the buffer member 160 is arranged between the upper surface of the shoulder of the rotating shaft 142 and the lower end surface of the mounting portion 122 .

[0115] Alternatively, along the axial direction of the rotating shaft 142 , a buffer member 160 is disposed between the top surface of the eccentric shaft 145 and the bottom wall of the mounting groove 123 , and between the upper surface of the shoulder of the rotating shaft 142 and the lower end surface of the mounting portion 122 .

[0116] By providing a buffer member 160 between the rotating shaft 142 and the movable scroll 120, during the transportation of the compressor 100, it is possible to effectively avoid a rigid collision between the rotating shaft assembly 140 and the movable scroll 120 due to axial movement, thereby reducing the wear of the rotating shaft assembly 140 and the movable scroll 120 due to the rigid collision, extending the service life of the compressor 100, and improving the reliability and performance of the compressor 100.

[0117] Optionally, the disk body 121 and the mounting portion 122 are an integral structure.

[0118] In some embodiments, optionally, when at least part of the buffer member 160 is disposed between a side of the eccentric shaft 145 away from the shaft body 144 and a groove wall of the mounting groove 123, the buffer member 160 is disposed on one of the side of the eccentric shaft 145 away from the shaft body 144 and the groove wall of the mounting groove 123, and has a second gap with the other along the axial direction of the rotating shaft 142.

[0119] In this embodiment, it is defined that at least a portion of the buffer 160 is disposed between a side surface of the eccentric shaft 145 away from the shaft body 144 and a groove wall of the installation groove 123. Specifically, the buffer 160 is disposed on a side surface of the eccentric shaft 145 away from the shaft body 144, and along the axial direction of the rotating shaft 142, a second gap is provided between the buffer 160 and the groove wall of the installation groove 123. Alternatively, the buffer 160 is disposed on the groove wall of the installation groove 123, and along the axial direction of the rotating shaft 142, a second gap is provided between the buffer 160 and a side surface of the eccentric shaft 145 away from the shaft body 144.

[0120] It is understandable that during the operation of the compressor 100, when the rotating shaft 142 drives the movable scroll 120 to rotate linearly relative to the fixed scroll 110, there will also be relative movement between the rotating shaft 142 and the movable scroll 120. By forming a second gap between the buffer member 160 and the groove wall of the mounting groove 123 or the side of the eccentric shaft 145 away from the shaft body 144, during the transportation of the compressor 100, it is possible to avoid a rigid collision between the rotating shaft assembly 140 and the movable scroll 120. During the operation of the compressor 100, it is possible to prevent interference between the buffer member 160 and the movable scroll 120 or the rotating shaft 142, thereby ensuring the normal operation of the compressor 100 and improving the reliability and performance of the compressor 100.

[0121] Optionally, along the axial direction of the rotating shaft 142 , the height of the second gap is less than or equal to 3 mm.

[0122] Optionally, the buffer member 160 may be fixed to the rotating shaft 142 or the movable scroll 120 by bonding or welding.

[0123] Optionally, the compressor 100 further includes a retaining spring, and the buffer member 160 is connected to the rotating shaft 142 or the movable scroll 120 via the retaining spring.

[0124] Optionally, the rotating shaft 142 or the movable scroll 120 is provided with a slot 151 , and a portion of the buffer 160 is embedded in the slot 151 .

[0125] In some embodiments, optionally, when at least part of the buffer member 160 is disposed between a side surface of the shaft body 144 facing the movable scroll 120 and the mounting portion 122, the buffer member 160 is disposed on a side surface of the shaft body 144 facing the movable scroll 120, and has a third gap along the axial direction of the rotating shaft 142 with an end of the mounting portion 122 facing away from the fixed scroll 110.

[0126] In this embodiment, it is defined that at least a portion of the buffer member 160 is disposed between a side surface of the shaft body 144 facing the movable scroll 120 and the mounting portion 122. Specifically, the buffer member 160 is disposed on a side surface of the shaft body 144 facing the movable scroll 120, and along the axial direction of the rotating shaft 142, a third gap is present between the buffer member 160 and an end of the mounting portion 122 facing away from the disk body 121.

[0127] It is understandable that during the operation of the compressor 100, when the rotating shaft 142 drives the movable scroll 120 to rotate linearly relative to the fixed scroll 110, there will also be relative movement between the rotating shaft 142 and the movable scroll 120. By forming a third gap between the buffer member 160 and the end of the mounting portion 122 that is away from the disk body 121, during the transportation of the compressor 100, it is possible to avoid a rigid collision between the rotating shaft assembly 140 and the movable scroll 120. During the operation of the compressor 100, it is possible to prevent interference between the buffer member 160 and the movable scroll 120, thereby ensuring the normal operation of the compressor 100 and improving the reliability and performance of the compressor 100.

[0128] Optionally, along the axial direction of the rotating shaft 142 , a height of the third gap is less than or equal to 3 mm.

[0129] According to a second aspect of the utility model, an air conditioner is provided, comprising a compressor 100 as provided in any of the above embodiments, and thus having all the beneficial technical effects of the compressor 100, which will not be described in detail herein.

[0130] Optionally, the compressor 100 comprises a scroll compressor.

[0131] Specifically, the compressor 100 includes a fixed scroll 110, a movable scroll 120, a rotating shaft assembly 140, a frame 150 and a buffer 160. Specifically, the fixed scroll 110 and the movable scroll 120 enclose a compression chamber 130, the compression chamber 130 is communicated with an exhaust port 111 on the fixed scroll 110, and the rotating shaft assembly 140 is connected to the movable scroll 120. Specifically, driven by the rotating shaft assembly 140, the movable scroll 120 performs translational rotation relative to the fixed scroll 110 to compress the refrigerant in the compression chamber 130, and the compressed refrigerant is discharged through the exhaust port 111 when it reaches the exhaust pressure.

[0132] The frame 150 is disposed on a side of the movable scroll 120 away from the fixed scroll 110 , and the frame 150 is connected to the fixed scroll 110 to support the movable scroll 120 .

[0133] It is understandable that during the transportation of the compressor 100, the shaft assembly 140 cannot be completely fixed, which will cause axial displacement, that is, up and down movement, causing the shaft assembly 140 to collide with its adjacent components, causing wear of the shaft assembly 140 and its adjacent components, reducing the service life of the compressor 100 and affecting the performance of the compressor 100.

[0134] Along the axial direction of the shaft assembly 140, at least part of the buffer 160 is disposed between the shaft assembly 140 and the movable scroll 120. Alternatively, along the axial direction of the shaft assembly 140, at least part of the buffer 160 is disposed between the shaft assembly 140 and the frame 150. Alternatively, along the axial direction of the shaft assembly 140, buffers 160 are disposed between the shaft assembly 140 and the movable scroll 120, and between the shaft assembly 140 and the frame 150. The specific configuration can be based on actual needs.

[0135] That is, a buffer member 160 is arranged on the axial movement path of the rotating shaft assembly 140, which can play a buffering role during the transportation of the compressor 100, effectively solving the problem of rigid collision between the rotating shaft assembly 140 and other components due to the axial movement of the rotating shaft assembly 140, avoiding wear of the rotating shaft assembly 140 and its adjacent components due to collision, especially wear between the rotating shaft assembly 140 and the movable scroll 120 due to rigid collision, thereby extending the service life of the compressor 100 and improving the reliability and performance of the compressor 100.
