Description

Technical Field

[0001] The utility model relates to the technical field of compressors, and in particular to a movable scroll, a compressor and a refrigeration device. Background Art

[0002] At present, the scroll compressor in the related art generally includes a movable scroll and a fixed scroll that mesh with each other, and a series of compression chambers formed between the two for compression. When the drive shaft of the driving mechanism rotates, the movable scroll can be driven to translate relative to the fixed scroll via the crank pin of the drive shaft to compress the refrigerant in the compression chamber.

[0003] However, during the operation of the scroll compressor, the movable scroll is generally in a slightly tilted state, causing local contact stress concentration on the end faces where the fixed scroll and the movable scroll are in contact, resulting in greater wear on the end faces where the fixed scroll and the movable scroll are in contact. Utility Model Content

[0004] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the present utility model provides a movable scroll.

[0006] A second aspect of an embodiment of the utility model provides a compressor.

[0007] A third aspect of the embodiments of the present utility model provides a refrigeration device.

[0008] In view of this, according to the first aspect of an embodiment of the utility model, a movable scroll plate is provided, which comprises: a movable scroll tooth; an end plate, wherein the movable scroll tooth is arranged on one side of the end plate along the axial direction of the end plate; a buffer groove, which is arranged on the side of the end plate away from the movable scroll tooth along the axial direction of the end plate and is arranged close to the outer peripheral wall of the end plate; wherein the buffer groove comprises a first groove section and a second groove section which are connected, wherein at least a portion of the first groove section extends along the circumferential direction of the end plate, and at least a portion of the second groove section extends along the radial direction of the end plate.

[0009] The movable scroll provided by the embodiment of the utility model includes a movable scroll tooth, an end plate and a buffer groove. Specifically, along the axial direction of the end plate, the movable scroll tooth is arranged on one side of the end plate, and the buffer groove is arranged on the side of the end plate away from the movable scroll tooth. That is to say, the movable scroll tooth and the buffer groove are respectively arranged on both sides of the axial direction of the end plate.

[0010] In detail, along the axial direction of the end plate, the end plate includes a first end face and a second end face opposite to each other, the movable scroll is located on the first end face, and the buffer groove is located on the second end face. It can be understood that the first end face is used to contact and cooperate with the end face of the fixed scroll. Since the buffer groove is arranged on the second end face, it is conducive to ensuring the sealing of the compression chamber formed by the fixed scroll and the movable scroll, and ensuring the reliability of the compressor having the movable scroll.

[0011] It is understandable that during the operation of the compressor, the orbiting scroll is always in a slightly tilted state, so that stress concentration occurs between the area of ​​the first end face close to the outer peripheral wall of the end plate and the end face of the fixed scroll, resulting in increased wear on the end faces of the fixed scroll and the orbiting scroll where they contact each other.

[0012] The buffer groove is arranged on the side of the end plate axially away from the movable scroll tooth, and the buffer groove is arranged close to the outer peripheral wall of the end plate. That is to say, the thickness of the end plate close to the outer peripheral wall is thinned, thereby effectively reducing the stiffness of the end plate close to the outer peripheral wall and increasing the elastic deformation of the end plate and the end face of the static scroll in the axial contact area, which is beneficial to increase the effective contact area between the end plate and the end face of the static scroll, reduce the contact surface pressure, and thus effectively improve the wear resistance of the end plate and the end face of the static scroll during the operation of the compressor, reduce wear, and help to extend the service life of the compressor and improve the performance of the compressor.

[0013] The buffer groove includes a first groove section and a second groove section, wherein the first groove section and the second groove section are connected. Specifically, at least part of the first groove section extends along the circumference of the end plate, thereby increasing the area of ​​the buffer region formed near the outer peripheral wall of the end plate and reducing the stiffness of the end plate near the outer peripheral wall.

[0014] At least part of the second groove segment extends radially along the end plate, thereby disconnecting the continuous structure on at least one side of the first groove segment in the radial direction of the end plate, which is beneficial to further reduce the stiffness of the end plate close to the outer wall area, increase the elastic deformation of the end plate close to the outer wall area, and enhance the buffering effect.

[0015] Optionally, the second slot segment is located radially inward of the first slot segment, and / or the second slot segment is located radially outward of the first slot segment. The specific configuration can be made according to actual needs.

[0016] Optionally, the movable scroll and the end plate are an integrated structure to improve the reliability of the movable scroll. At the same time, it is also beneficial to reduce the manufacturing difficulty and manufacturing cost of the movable scroll.

[0017] It is worth noting that the movable scroll extends from the approximate center position of the end plate along the spiral profile direction from the inside to the outside.

[0018] In addition, the movable scroll provided by the above technical solution of the utility model also has the following additional technical features:

[0019] In some technical solutions, optionally, the second slot segment is located radially outside the first slot segment.

[0020] In this technical solution, the second groove segment is defined as being located radially outside the first groove segment. Since at least part of the second groove segment extends radially, the continuous structure on the end plate located outside the first groove segment is disconnected, which is beneficial to further reduce the stiffness of the end plate close to the outer peripheral wall area, increase the elastic deformation of the end plate close to the outer peripheral wall area, and enhance the buffering effect, thereby effectively improving the wear resistance of the end plate and the end face of the static scroll disk during the operation of the compressor, reducing wear, and is beneficial to extending the service life of the compressor and improving the performance of the compressor.

[0021] In some technical solutions, optionally, along the radial direction of the end plate, one end of the second slot segment facing away from the first slot segment passes through the outer peripheral wall of the end plate.

[0022] In this technical solution, the end of the second groove segment away from the first groove segment is defined to radially penetrate the outer peripheral wall of the end plate, that is, the end of the second groove segment away from the first groove segment forms an opening on the outer peripheral wall of the end plate, thereby further reducing the stiffness of the end plate close to the outer peripheral wall area, increasing the elastic deformation of the end plate close to the outer peripheral wall area, and improving the buffering effect, thereby effectively improving the wear resistance of the end plate and the end face of the static scroll disk during the operation of the compressor, reducing wear, and helping to extend the service life of the compressor and improve the performance of the compressor.

[0023] In some technical solutions, optionally, there are multiple second slot segments, and the multiple second slot segments are arranged at intervals along the circumference of the end plate, and the multiple second slot segments are respectively connected to the first slot segments.

[0024] In this technical solution, the number of the second slot segments is defined as multiple. Specifically, the multiple second slot segments are arranged at intervals along the circumferential direction, and each second slot segment is connected to the first slot segment.

[0025] It can be understood that the more the number of second groove segments is, that is, the more disconnected structures are formed in the area where the end plate is located on at least one side of the first groove segment in the radial direction, the better the buffering effect is, thereby effectively improving the wear resistance of the end plate and the end face of the static scroll plate during the operation of the compressor and reducing wear.

[0026] In some technical schemes, optionally, along the radial direction of the end plate, the first groove section includes a first groove wall and a second groove wall relative to each other, and the first groove wall is closer to the outer peripheral wall of the end plate than the second groove wall; wherein, along the radial direction of the end plate, there is a distance between the first groove wall and the outer peripheral wall of the end plate.

[0027] In this technical solution, it is defined that the first groove section includes a first groove wall and a second groove wall. Specifically, along the radial direction of the end plate, the first groove wall is opposite to the second groove wall, and the first groove wall is closer to the outer peripheral wall of the end plate than the second groove wall, that is, the first groove wall is the outer wall and the second groove wall is the inner wall.

[0028] There is a radial spacing between the first groove wall and the outer peripheral wall of the end plate, that is, a certain spacing is reserved between the radial outer side of the first groove section and the outer peripheral wall of the end plate. Therefore, during the manufacturing process of the movable scroll, when the end plate is fixed by using tooling and fixtures, the surface reserved by the end plate at the spacing can form a supporting surface, thereby improving the fixing effect of the end plate, facilitating the processing and manufacturing of the movable scroll, improving production efficiency, and helping to reduce the production cost of the movable scroll.

[0029] That is, it can reduce the stiffness of the end plate near the outer peripheral wall and increase the elastic deformation of the axial contact area between the end plate and the end face of the static scroll disk, which is beneficial to increase the effective contact area between the end plate and the end face of the static scroll disk and reduce the contact surface pressure, thereby effectively improving the wear resistance of the end plate and the end face of the static scroll disk during the operation of the compressor while being compatible with the use of tooling and fixtures.

[0030] In some technical solutions, optionally, the spacing d satisfies 2mm≤d≤10mm.

[0031] In this technical solution, the range of the radial distance between the first groove wall and the outer peripheral wall of the end plate is limited.

[0032] It is understandable that if the spacing is too small, i.e., less than 2 mm, the area of ​​the support surface reserved for the end plate at the spacing is too small, which is not conducive to the fixation of the end plate during the processing. In addition, if the spacing is too large, i.e., greater than 10 mm, the rigidity of the end plate near the outer peripheral wall area is large, which increases the wear of the contact end surface between the end plate and the fixed scroll.

[0033] By limiting the spacing to between 2 mm and 10 mm, it is possible to ensure the buffering effect of the end plate close to the outer wall area while enabling reliable fixation of the movable scroll by means of tooling and fixtures during the processing and manufacturing of the movable scroll, thereby facilitating the processing and manufacturing of the movable scroll, improving production efficiency, and helping to reduce the production cost of the movable scroll.

[0034] Optionally, the distance d satisfies 6mm≤d≤8mm.

[0035] In some technical schemes, optionally, along the circumference of the end plate, the first slot segment includes a first end and a second end opposite to each other; wherein, along the radial direction of the end plate, a line connecting the first end and the central axis of the end plate is a first line, a line connecting the second end and the central axis of the end plate is a second line, and an angle α between the first line and the second line satisfies, α≥90°.

[0036] In this technical solution, it is defined that the first groove segment includes a first end and a second end opposite to each other in the circumferential direction. Specifically, along the radial direction of the end plate, the line connecting the central axis of the end plate and the first end is the first line, and the line connecting the central axis of the end plate and the second end is the second line. The angle between the first line and the second line is greater than or equal to 90°. That is to say, the angle range of the first groove segment extending in the circumferential direction is not less than 90°, thereby effectively increasing the area of ​​the buffer structure formed by the end plate near the outer wall area, enhancing the buffer effect, and further improving the wear resistance of the contact area between the end plate and the end face of the static scroll disk.

[0037] In some technical solutions, optionally, the movable scroll further includes a fixed groove, which is provided on the outer peripheral wall of the end plate and extends in the radial direction of the end plate. Along the axial direction of the end plate, the fixed groove and the second groove section are staggered.

[0038] In this technical solution, it is defined that the movable scroll also includes a fixing groove, specifically, the fixing groove is arranged on the outer peripheral wall of the end plate, and the fixing groove extends in the radial direction of the end plate. It can be understood that during the manufacturing process of the movable scroll, the end plate can be fixed by using a tool and a fixture through the fixing groove.

[0039] Along the axial direction of the end plate, the fixed groove and the second groove section are staggered, that is, at the position where the fixed groove is located, the overall thickness of the end plate is thicker, thereby reducing the rigidity of the end plate close to the outer peripheral wall area while ensuring the structural strength of the end plate close to the outer peripheral wall area, avoiding breakage at this position during the manufacturing process of the movable scroll disk, and improving the yield rate of the movable scroll disk.

[0040] In some technical solutions, optionally, there are multiple buffer grooves, and the multiple buffer grooves are arranged at intervals along the circumference of the end plate.

[0041] In this technical solution, the number of buffer grooves is limited to multiple. Specifically, the multiple buffer grooves are arranged at intervals along the circumference of the end plate, so that a buffer structure can be formed in the area of ​​the end plate in the entire circumference and close to the outer peripheral wall, which is beneficial to further enhance the buffering effect of the end plate close to the outer peripheral wall area, increase the elastic deformation of the end plate and the static scroll end face in the axial contact area, increase the effective contact area between the end plate and the static scroll end face, reduce the contact surface pressure, and thus effectively improve the wear resistance of the end plate and the static scroll end face during the operation of the compressor, reduce wear, and help to extend the service life of the compressor and improve the performance of the compressor.

[0042] In some technical solutions, optionally, at least two buffer grooves are symmetrically arranged about the central axis of the end plate.

[0043] In this technical solution, at least two buffer grooves are symmetrically arranged about the central axis of the end plate. During the operation of the compressor, it is beneficial to ensure that the forces at various parts of the end plate are balanced, thereby extending the service life of the movable scroll. At the same time, it is also beneficial to reduce the manufacturing difficulty of the movable scroll, thereby reducing the production cost of the movable scroll.

[0044] According to a second aspect of the present invention, a compressor is provided, comprising a movable scroll provided by any of the above technical solutions, thereby having all the beneficial technical effects of the movable scroll, which will not be repeated here.

[0045] Furthermore, the compressor also includes a stationary scroll plate, the stationary scroll teeth of which are cooperatively connected with the movable scroll teeth; a frame, which is arranged on the side of the end plate away from the movable scroll teeth and is connected to the stationary scroll plate for supporting the movable scroll plate.

[0046] The compressor provided by the embodiment of the utility model includes a movable scroll, a fixed scroll and a frame. Specifically, the fixed scroll of the fixed scroll is connected with the movable scroll, so that the fixed scroll and the movable scroll are enclosed to form a compression chamber. Optionally, the fixed scroll is provided with an exhaust port, and the exhaust port is connected to the compression chamber. Specifically, during the operation of the compressor, the crankshaft can drive the movable scroll to rotate relative to the fixed scroll to compress the refrigerant in the compression chamber. When the exhaust pressure is reached, the compressed high-temperature and high-pressure refrigerant is discharged through the exhaust port.

[0047] The frame is arranged on a side of the end plate away from the movable scroll, and the frame is connected to the fixed scroll to support the movable scroll and ensure the cooperation between the fixed scroll and the movable scroll.

[0048] In addition, the compressor provided by the above technical solution of the utility model also has the following additional technical features:

[0049] In some technical solutions, optionally, a thrust surface is provided on the side of the frame facing the end plate; wherein, along the radial direction of the end plate, the distance D between the groove wall of the buffer groove close to the central axis of the end plate and the central axis of the end plate is 1 , the distance D between the outer edge of the thrust surface and the center axis of the end plate 2 , and the orbiting radius R of the orbiting scroll, satisfying D 1 >D 2 +R.

[0050] In this technical solution, it is defined that the frame is provided with a thrust surface. It can be understood that the frame supports the movable scroll through the thrust surface.

[0051] The distance between the buffer groove wall close to the end plate centerline in the radial direction and the end plate centerline is D 1 , the distance between the outer edge of the thrust surface and the center axis of the end plate is D 2, that is, the radius of the outer circumference of the thrust surface is D 2 , the orbiting radius of the orbiting scroll is R, specifically, D 1 Greater than D 2 The sum of R and R can effectively prevent the outer edge of the thrust surface from entering the buffer groove and causing wear against the groove wall of the buffer groove during the translational rotation of the orbiting scroll relative to the stationary scroll. This is beneficial to further extend the service life of the compressor and ensure the reliable operation of the compressor.

[0052] According to the third aspect of the utility model, a refrigeration device is provided, including a movable scroll or a compressor as provided by any of the above technical solutions, thereby having all the beneficial technical effects of the movable scroll or the compressor, which will not be repeated here.

DETAILED DESCRIPTION

[0062] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0063] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0064] Refer to the following Figures 1 to 5 The movable scroll 100, the compressor 200 and the refrigeration equipment provided according to some embodiments of the present invention are described.

[0065] In one embodiment according to the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a movable scroll plate 100 is proposed, and the movable scroll plate 100 includes: a movable scroll tooth 110; an end plate 120, wherein the movable scroll tooth 110 is arranged on one side of the end plate 120 along the axial direction of the end plate 120; a buffer groove 130, which is arranged on the side of the end plate 120 away from the movable scroll tooth 110 along the axial direction of the end plate 120, and is arranged close to the outer peripheral wall 121 of the end plate 120; wherein the buffer groove 130 includes a first groove section 131 and a second groove section 132 which are connected, at least a portion of the first groove section 131 extends along the circumferential direction of the end plate 120, and at least a portion of the second groove section 132 extends along the radial direction of the end plate 120.

[0066] The movable scroll plate 100 provided in the embodiment of the utility model includes a movable scroll tooth 110, an end plate 120 and a buffer groove 130. Specifically, along the axial direction of the end plate 120, the movable scroll tooth 110 is arranged on one side of the end plate 120, and the buffer groove 130 is arranged on the side of the end plate 120 away from the movable scroll tooth 110. That is to say, the movable scroll tooth 110 and the buffer groove 130 are respectively arranged on both sides of the axial direction of the end plate 120.

[0067] In detail, along the axial direction of the end plate 120, the end plate 120 includes a first end 135 surface and a second end 136 surface facing each other, the movable scroll 110 is located on the first end 135 surface, and the buffer groove 130 is located on the second end 136 surface. It can be understood that the first end 135 surface is used to contact and cooperate with the end surface of the fixed scroll 210. Since the buffer groove 130 is arranged on the second end 136 surface, it is beneficial to ensure the sealing of the compression chamber formed by the fixed scroll 210 and the movable scroll 100, and ensure the reliability of the compressor 200 having the movable scroll 100.

[0068] It is understandable that during the operation of the compressor 200, the orbiting scroll 100 is always in a slightly tilted state, so that stress concentration occurs between the area of ​​the first end 135 surface close to the outer peripheral wall 121 of the end plate 120 and the end surface of the fixed scroll 210, resulting in increased wear on the end surfaces of the fixed scroll 210 and the orbiting scroll 100 where they are in contact with each other.

[0069] The buffer groove 130 is arranged on the side of the end plate 120 axially away from the movable scroll tooth 110, and the buffer groove 130 is arranged close to the outer peripheral wall 121 of the end plate 120. That is to say, the thickness of the end plate 120 close to the outer peripheral wall 121 is thinned, thereby effectively reducing the stiffness of the end plate 120 close to the outer peripheral wall 121, and increasing the elastic deformation of the end plate 120 and the end face of the static scroll plate 210 in the axial contact area, which is beneficial to increase the effective contact area between the end plate 120 and the end face of the static scroll plate 210, reduce the contact surface pressure, and thus effectively improve the wear resistance of the end plate 120 and the end face of the static scroll plate 210 during the operation of the compressor 200, reduce wear, and help to extend the service life of the compressor 200 and improve the performance of the compressor 200.

[0070] The buffer groove 130 includes a first groove section 131 and a second groove section 132, wherein the first groove section 131 and the second groove section 132 are connected. Specifically, at least a portion of the first groove section 131 extends along the circumference of the end plate 120, thereby increasing the area of ​​the buffer region formed near the outer peripheral wall 121 of the end plate 120 and reducing the stiffness of the region of the end plate 120 near the outer peripheral wall 121.

[0071] At least part of the second groove section 132 extends radially along the end plate 120, so that the continuous structure on at least one side of the first groove section 131 on the end plate 120 in the radial direction is disconnected, which is beneficial to further reduce the stiffness of the end plate 120 close to the outer wall 121, increase the elastic deformation of the end plate 120 close to the outer wall 121, and enhance the buffering effect.

[0072] Optionally, the second slot segment 132 is located radially inward of the first slot segment 131, and / or the second slot segment 132 is located radially outward of the first slot segment 131. The configuration may be made according to actual needs.

[0073] Optionally, the movable scroll 110 and the end plate 120 are an integrated structure to improve the reliability of the movable scroll 100 , and at the same time, it is also helpful to reduce the manufacturing difficulty and manufacturing cost of the movable scroll 100 .

[0074] It is worth noting that the movable scroll 110 extends from the approximate center position of the end plate 120 along the spiral profile direction from the inside to the outside.

[0075] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the second slot segment 132 is located radially outside the first slot segment 131 .

[0076] In this embodiment, the second groove segment 132 is defined as being located radially outside the first groove segment 131. Since at least a portion of the second groove segment 132 extends radially, the continuous structure on the end plate 120 located outside the first groove segment 131 is disconnected, which is beneficial to further reduce the stiffness of the end plate 120 near the outer peripheral wall 121, increase the elastic deformation of the end plate 120 near the outer peripheral wall 121, and enhance the buffering effect, thereby effectively improving the wear resistance of the end plate 120 and the end surface of the static scroll plate 210 during the operation of the compressor 200, reducing wear, and is beneficial to extending the service life of the compressor 200 and enhancing the performance of the compressor 200.

[0077] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, along the radial direction of the end plate 120 , one end of the second slot segment 132 away from the first slot segment 131 passes through the outer peripheral wall 121 of the end plate 120 .

[0078] In this embodiment, the end of the second groove segment 132 that is away from the first groove segment 131 is defined to radially penetrate the outer peripheral wall 121 of the end plate 120, that is, the end of the second groove segment 132 that is away from the first groove segment 131 forms an opening on the outer peripheral wall 121 of the end plate 120, thereby further reducing the stiffness of the end plate 120 close to the outer peripheral wall 121, increasing the elastic deformation of the end plate 120 close to the outer peripheral wall 121, and improving the buffering effect, thereby effectively improving the wear resistance of the end plate 120 and the end surface of the static scroll plate 210 during the operation of the compressor 200, reducing wear, and being beneficial to extending the service life of the compressor 200 and improving the performance of the compressor 200.

[0079] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, there are multiple second slot segments 132 , and the multiple second slot segments 132 are arranged at intervals along the circumference of the end plate 120 , and the multiple second slot segments 132 are respectively connected to the first slot segments 131 .

[0080] In this embodiment, the number of the second slot segments 132 is defined as multiple. Specifically, the multiple second slot segments 132 are arranged at intervals along the circumferential direction, and each second slot segment 132 is connected to the first slot segment 131 .

[0081] It can be understood that the more the number of second groove segments 132 is, that is, the more disconnection structures are formed in the area where the end plate 120 is located on at least one side of the first groove segment 131 in the radial direction, the better the buffering effect is, thereby effectively improving the wear resistance of the end plate 120 and the end surface of the static scroll plate 210 during the operation of the compressor 200 and reducing wear.

[0082] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, along the radial direction of the end plate 120, the first groove section 131 includes a first groove wall 133 and a second groove wall 134 relative to each other, and the first groove wall 133 is closer to the outer peripheral wall 121 of the end plate 120 than the second groove wall 134; wherein, along the radial direction of the end plate 120, there is a spacing between the first groove wall 133 and the outer peripheral wall 121 of the end plate 120.

[0083] In this embodiment, the first groove section 131 is defined to include a first groove wall 133 and a second groove wall 134. Specifically, along the radial direction of the end plate 120, the first groove wall 133 is opposite to the second groove wall 134, and the first groove wall 133 is closer to the outer peripheral wall 121 of the end plate 120 than the second groove wall 134, that is, the first groove wall 133 is an outer wall, and the second groove wall 134 is an inner wall.

[0084] There is a radial spacing between the first groove wall 133 and the outer peripheral wall 121 of the end plate 120, that is, a certain spacing is reserved between the radial outer side of the first groove section 131 and the outer peripheral wall 121 of the end plate 120, so that during the manufacturing process of the movable scroll 100, when the end plate 120 is fixed by using tooling and fixtures, the surface of the end plate 120 reserved at the spacing can form a supporting surface, thereby improving the fixing effect of the end plate 120, facilitating the processing and manufacturing of the movable scroll 100, improving production efficiency, and helping to reduce the production cost of the movable scroll 100.

[0085] That is, it is able to reduce the stiffness of the end plate 120 near the outer peripheral wall 121 and increase the elastic deformation of the axial contact area between the end plate 120 and the end face of the static scroll plate 210, which is beneficial to increase the effective contact area between the end plate 120 and the end face of the static scroll plate 210 and reduce the contact surface pressure, thereby effectively improving the wear resistance of the end plate 120 and the end face of the static scroll plate 210 during the operation of the compressor 200 while being compatible with the use of tooling and fixtures.

[0086] like Figure 1 As shown, in some embodiments, optionally, the spacing d satisfies 2mm≤d≤10mm.

[0087] In this embodiment, a range of values ​​of the radial distance between the first groove wall 133 and the outer peripheral wall 121 of the end plate 120 is defined.

[0088] It is understandable that if the spacing is too small, i.e., less than 2 mm, the area of ​​the support surface reserved by the end plate 120 at the spacing is too small, which is not conducive to the fixation of the end plate 120 during the processing. In addition, if the spacing is too large, i.e., greater than 10 mm, the rigidity of the end plate 120 near the outer peripheral wall 121 is relatively large, which increases the wear of the contact end surface between the end plate 120 and the fixed scroll 210.

[0089] By limiting the spacing to between 2 mm and 10 mm, it is possible to ensure the buffering effect of the end plate 120 close to the outer wall 121 while enabling reliable fixation by means of tooling and fixtures during the processing and manufacturing of the movable scroll 100, thereby facilitating the processing and manufacturing of the movable scroll 100, improving production efficiency, and helping to reduce the production cost of the movable scroll 100.

[0090] Optionally, the distance d satisfies 6mm≤d≤8mm.

[0091] like Figure 1 As shown, in some embodiments, optionally, along the circumference of the end plate 120, the first slot segment 131 includes a first end 135 and a second end 136 opposite to each other; wherein, along the radial direction of the end plate 120, a line connecting the first end 135 and the central axis 122 of the end plate 120 is a first line 140, and a line connecting the second end 136 and the central axis 122 of the end plate 120 is a second line 150, and an angle α between the first line 140 and the second line 150 satisfies, α≥90°.

[0092] In this embodiment, the first groove section 131 is defined to include a first end 135 and a second end 136 opposite to each other in the circumferential direction. Specifically, along the radial direction of the end plate 120, a line connecting the central axis 122 of the end plate 120 and the first end 135 is a first line 140, and a line connecting the central axis 122 of the end plate 120 and the second end 136 is a second line 150. The angle between the first line 140 and the second line 150 is greater than or equal to 90°. That is to say, the angle range of the first groove section 131 extending in the circumferential direction is not less than 90°, thereby effectively increasing the area of ​​the buffer structure formed by the end plate 120 in the area close to the outer peripheral wall 121, enhancing the buffer effect, and further improving the wear resistance of the contact area between the end plate 120 and the end face of the static scroll plate 210.

[0093] like Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, optionally, the orbiting scroll 100 further includes a fixed groove 160 , which is disposed on the outer peripheral wall 121 of the end plate 120 and extends in the radial direction of the end plate 120 , and along the axial direction of the end plate 120 , the fixed groove 160 and the second groove section 132 are staggered.

[0094] In this embodiment, it is defined that the movable scroll 100 further includes a fixing groove 160. Specifically, the fixing groove 160 is provided on the outer peripheral wall 121 of the end plate 120, and the fixing groove 160 extends in the radial direction of the end plate 120. It can be understood that during the manufacturing process of the movable scroll 100, the end plate 120 can be fixed through the fixing groove 160 by using a tool and a fixture.

[0095] Along the axial direction of the end plate 120, the fixed groove 160 and the second groove section 132 are staggered, that is, at the position where the fixed groove 160 is located, the overall thickness of the end plate 120 is thicker, thereby ensuring the structural strength of the end plate 120 close to the outer peripheral wall 121 while reducing the rigidity of the end plate 120 close to the outer peripheral wall 121, avoiding fracture at this position during the manufacturing process of the movable scroll 100, and improving the yield of the movable scroll 100.

[0096] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, there are multiple buffer grooves 130 , and the multiple buffer grooves 130 are arranged at intervals along the circumference of the end plate 120 .

[0097] In this embodiment, the number of buffer grooves 130 is limited to multiple. Specifically, the multiple buffer grooves 130 are arranged at intervals along the circumference of the end plate 120, so that a buffer structure can be formed in the entire circumference of the end plate 120 and in the area close to the outer peripheral wall 121, which is beneficial to further enhance the buffering effect of the end plate 120 close to the outer peripheral wall 121, increase the elastic deformation of the axial contact area between the end plate 120 and the end face of the static scroll plate 210, increase the effective contact area between the end plate 120 and the end face of the static scroll plate 210, reduce the contact surface pressure, and thus effectively improve the wear resistance of the end plate 120 and the end face of the static scroll plate 210 during the operation of the compressor 200, reduce wear, and help to extend the service life of the compressor 200 and improve the performance of the compressor 200.

[0098] In some embodiments, optionally, at least two buffer grooves 130 are symmetrically arranged about the central axis 122 of the end plate 120 .

[0099] In this embodiment, at least two buffer grooves 130 are symmetrically arranged about the central axis 122 of the end plate 120. During the operation of the compressor 200, it is beneficial to balance the forces at various parts of the end plate 120, thereby extending the service life of the movable scroll 100. At the same time, it is also beneficial to reduce the manufacturing difficulty of the movable scroll 100, thereby reducing the production cost of the movable scroll 100.

[0100] According to a second aspect of the present invention, a compressor 200 is provided, comprising a movable scroll 100 as provided in any of the above embodiments, and thus having all the beneficial technical effects of the movable scroll 100, which will not be described in detail herein.

[0101] like Figure 5 As shown, further, the compressor 200 also includes a stationary scroll 210, and a stationary scroll tooth 211 of the stationary scroll 210 is cooperatively connected with the movable scroll tooth 110; a frame 220 is arranged on the side of the end plate 120 away from the movable scroll tooth 110, and is connected to the stationary scroll 210, for supporting the movable scroll 100.

[0102] The compressor 200 provided by the embodiment of the utility model includes an orbiting scroll 100, a fixed scroll 210 and a frame 220. Specifically, the fixed scroll 211 of the fixed scroll 210 is connected with the movable scroll 110, so that the fixed scroll 210 and the orbiting scroll 100 enclose a compression chamber. Optionally, the fixed scroll 210 is provided with an exhaust port, and the exhaust port is connected to the compression chamber. Specifically, during the operation of the compressor 200, the crankshaft can drive the orbiting scroll 100 to rotate relative to the fixed scroll 210 to compress the refrigerant in the compression chamber. When the exhaust pressure is reached, the compressed high-temperature and high-pressure refrigerant is discharged through the exhaust port.

[0103] The frame 220 is disposed on a side of the end plate 120 away from the orbiting scroll 110 , and the frame 220 is connected to the fixed scroll 210 to support the orbiting scroll 100 and ensure the fit between the fixed scroll 210 and the orbiting scroll 100 .

[0104] Along the axial direction of the end plate 120 , the movable volute 110 is arranged on one side of the end plate 120 , and the buffer groove 130 is arranged on the side of the end plate 120 away from the movable volute 110 , that is, the movable volute 110 and the buffer groove 130 are respectively arranged on both sides of the axial direction of the end plate 120 .

[0105] In detail, along the axial direction of the end plate 120, the end plate 120 includes a first end 135 surface and a second end 136 surface facing each other, the movable scroll 110 is located on the first end 135 surface, and the buffer groove 130 is located on the second end 136 surface. It can be understood that the first end 135 surface is used to contact and cooperate with the end surface of the fixed scroll 210. Since the buffer groove 130 is arranged on the second end 136 surface, it is beneficial to ensure the sealing of the compression chamber formed by the fixed scroll 210 and the movable scroll 100, and ensure the reliability of the compressor 200 having the movable scroll 100.

[0106] It is understandable that during the operation of the compressor 200, the orbiting scroll 100 is always in a slightly tilted state, so that stress concentration occurs between the area of ​​the first end 135 surface close to the outer peripheral wall 121 of the end plate 120 and the end surface of the fixed scroll 210, resulting in increased wear on the end surfaces of the fixed scroll 210 and the orbiting scroll 100 where they are in contact with each other.

[0107] The buffer groove 130 is arranged on the side of the end plate 120 axially away from the movable scroll tooth 110, and the buffer groove 130 is arranged close to the outer peripheral wall 121 of the end plate 120. That is to say, the thickness of the end plate 120 close to the outer peripheral wall 121 is thinned, thereby effectively reducing the stiffness of the end plate 120 close to the outer peripheral wall 121, and increasing the elastic deformation of the end plate 120 and the end face of the static scroll plate 210 in the axial contact area, which is beneficial to increase the effective contact area between the end plate 120 and the end face of the static scroll plate 210, reduce the contact surface pressure, and thus effectively improve the wear resistance of the end plate 120 and the end face of the static scroll plate 210 during the operation of the compressor 200, reduce wear, and help to extend the service life of the compressor 200 and improve the performance of the compressor 200.

[0108] The buffer groove 130 includes a first groove section 131 and a second groove section 132, wherein the first groove section 131 and the second groove section 132 are connected. Specifically, at least a portion of the first groove section 131 extends along the circumference of the end plate 120, thereby increasing the area of ​​the buffer region formed near the outer peripheral wall 121 of the end plate 120 and reducing the stiffness of the region of the end plate 120 near the outer peripheral wall 121.

[0109] At least part of the second groove section 132 extends radially along the end plate 120, so that the continuous structure on at least one side of the first groove section 131 on the end plate 120 in the radial direction is disconnected, which is beneficial to further reduce the stiffness of the end plate 120 close to the outer wall 121, increase the elastic deformation of the end plate 120 close to the outer wall 121, and enhance the buffering effect.

[0110] like Figure 3 and Figure 5As shown, in some embodiments, optionally, a thrust surface 221 is provided on one side of the frame 220 facing the end plate 120; wherein, along the radial direction of the end plate 120, the distance D between the groove wall of the buffer groove 130 close to the central axis 122 of the end plate 120 and the central axis 122 of the end plate 120 is 1 , the distance D between the outer edge of the thrust surface 221 and the center axis 122 of the end plate 120 2 , and the orbiting radius R of the orbiting scroll 100, satisfying D 1 >D 2 +R.

[0111] In this embodiment, it is defined that the frame 220 is provided with a thrust surface 221 . It can be understood that the frame 220 supports the orbiting scroll 100 via the thrust surface 221 .

[0112] The distance between the groove wall of the buffer groove 130 close to the center axis 122 of the end plate 120 in the radial direction and the center axis 122 of the end plate 120 is D 1 The distance between the outer edge of the thrust surface 221 and the center axis 122 of the end plate 120 is D 2 , that is, the radius of the outer periphery of the thrust surface 221 is D 2 , the orbiting radius of the orbiting scroll 100 is R, specifically, D 1 Greater than D 2 and R, so that during the translational rotation of the movable scroll 100 relative to the fixed scroll 210, the outer edge of the thrust surface 221 can be effectively prevented from entering the buffer groove 130 and then wearing against the groove wall of the buffer groove 130, which is beneficial to further extend the service life of the compressor 200 and ensure the reliable operation of the compressor 200.

[0113] According to the third aspect of the utility model, a refrigeration device is provided, including a movable scroll 100 or a compressor 200 as provided in any of the above embodiments, thereby having all the beneficial technical effects of the movable scroll 100 or the compressor 200, which will not be repeated here.
