The orbiting scroll comprises: an orbiting scroll wrap; an end plate, wherein along the axial direction of the end plate, the orbiting scroll wrap is arranged on one side of the end plate; and buffer grooves, wherein along the axial direction of the end plate, the buffer grooves are formed on the side of the end plate facing away from the orbiting scroll wrap, and are arranged close to the outer circumferential wall of the end plate. Each buffer groove comprises a first groove section and a second groove section in communication with each other, at least a part of the first groove section extends along the circumferential direction of the end plate, and at least a part of the second groove section extends along the radial direction of the end plate.

[0002] This application relates to the field of compressor technology, and more specifically, to a moving scroll plate, a compressor, and a refrigeration device. Background Technology

[0003] Currently, scroll compressors in related technologies generally include a moving scroll and a stationary scroll that mesh with each other, and a series of compression chambers formed between them for compression.

[0004] However, during the operation of a scroll compressor, the moving scroll is generally in a slightly tilted state, which causes local contact stress concentration at the end face where the stationary scroll and the moving scroll come into contact, resulting in greater wear on the end face where the stationary scroll and the moving scroll come into contact.

[0014] In some technical solutions, for example, the spacing d satisfies 2mm≤d≤10mm.

[0015] In some technical solutions, for example, along the circumference of the end plate, the first groove segment includes a first end and a second end facing away from each other; wherein, along the radial direction of the end plate, the line connecting the first end and the central axis of the end plate is the first connecting line, and the line connecting the second end and the central axis of the end plate is the second connecting line, and the angle α between the first connecting line and the second connecting line satisfies α≥90°.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0033] The moving scroll 100, compressor 200 and refrigeration equipment provided according to some embodiments of this application are described below with reference to Figures 1 to 5.

[0034] In one embodiment of this application, as shown in Figures 1, 2, 3 and 4, a moving scroll disk 100 is proposed. The moving scroll disk 100 includes: a moving scroll tooth 110; an end plate 120, with the moving scroll tooth 110 disposed on one side of the end plate 120 along the axial direction; and a buffer groove 130, disposed on the side of the end plate 120 away from the moving scroll tooth 110 and close to the outer peripheral wall 121 of the end plate 120 along the axial direction; wherein the buffer groove 130 includes a first groove segment 131 and a second groove segment 132 that are connected to each other, at least a portion of the first groove segment 131 extending circumferentially along the end plate 120, and at least a portion of the second groove segment 132 extending radially along the end plate 120.

[0035] The moving scroll plate 100 provided in this application embodiment includes a moving scroll tooth 110, an end plate 120 and a buffer groove 130. Specifically, along the axial direction of the end plate 120, the moving scroll tooth 110 is disposed on one side of the end plate 120, and the buffer groove 130 is disposed on the side of the end plate 120 away from the moving scroll tooth 110. That is, the moving scroll tooth 110 and the buffer groove 130 are respectively disposed on both sides of the end plate 120 in the axial direction.

[0036] 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 away from each other. The moving scroll gear 110 is located on the first end 135 surface, and the buffer groove 130 is located on the second end 136 surface. It is understood that the first end 135 surface is used for contact and engagement with the end face of the stationary scroll 210. Since the buffer groove 130 is located on the second end 136 surface, it helps to ensure the sealing of the compression cavity formed by the stationary scroll 210 and the moving scroll 100, thus ensuring the reliability of the compressor 200 having the moving scroll 100.

[0037] Understandably, during the operation of the compressor 200, the moving scroll 100 is always in a slightly tilted state, which causes stress concentration between the area of ​​the first end 135 face near the outer peripheral wall 121 of the end plate 120 and the end face of the stationary scroll 210, resulting in increased wear on the end faces of the stationary scroll 210 and the moving scroll 100 that come into contact with each other.

[0038] The buffer groove 130 is located on the side of the end plate 120 facing away from the moving scroll tooth 110 in the axial direction, and the buffer groove 130 is located close to the outer peripheral wall 121 of the end plate 120. That is to say, the thickness of the end plate 120 is reduced near the outer peripheral wall 121, thereby effectively reducing the rigidity of the end plate 120 near the outer peripheral wall 121, increasing the elastic deformation of the end plate 120 and the stationary scroll 210 end face in the axial direction, which is conducive to increasing the effective contact area between the end plate 120 and the stationary scroll 210 end face, reducing the contact surface pressure, and thus effectively improving the wear resistance of the end plate 120 and the stationary scroll 210 end face during the operation of the compressor 200, reducing wear, which is conducive to extending the service life of the compressor 200 and improving the performance of the compressor 200.

[0039] The buffer groove 130 includes a first groove segment 131 and a second groove segment 132, wherein the first groove segment 131 and the second groove segment 132 are connected. Specifically, at least a portion of the first groove segment 131 extends circumferentially along the end plate 120, thereby increasing the area of ​​the buffer region formed by the end plate 120 near the outer peripheral wall 121 and reducing the stiffness of the region of the end plate 120 near the outer peripheral wall 121.

[0040] At least a portion of the second groove segment 132 extends radially along the end plate 120, thereby breaking the continuous structure on the end plate 120 located on at least one side of the first groove segment 131 in the radial direction. This helps to further reduce the stiffness of the area of ​​the end plate 120 near the outer peripheral wall 121, increase the elastic deformation of the area of ​​the end plate 120 near the outer peripheral wall 121, and improve the buffering effect.

[0041] For example, the second groove segment 132 is located radially inside the first groove segment 131, and / or the second groove segment 132 is located radially outside the first groove segment 131. The specific configuration can be adjusted according to actual needs.

[0042] For example, the moving worm gear 110 and the end plate 120 are integrated into one structure to improve the reliability of the moving worm gear 100. At the same time, it also helps to reduce the manufacturing difficulty and manufacturing cost of the moving worm gear 100.

[0043] It is worth noting that the moving vortex 110 extends from the inside to the outside along a spiral profile from approximately the center of the end plate 120.

[0044] As shown in Figures 1 and 2, in some embodiments, for example, the second groove segment 132 is located radially outside the first groove segment 131.

[0045] In this embodiment, the second groove segment 132 is defined to be located radially outside the first groove segment 131. Since at least part of the second groove segment 132 extends radially, the continuous structure on the end plate 120 located outside the first groove segment 131 is broken. This helps to further reduce the stiffness of the area of ​​the end plate 120 near the outer peripheral wall 121, increase the elastic deformation of the area of ​​the end plate 120 near the outer peripheral wall 121, improve the buffering effect, and thus effectively improve the wear resistance of the end plate 120 and the end face of the stationary scroll plate 210 during the operation of the compressor 200, reduce wear, extend the service life of the compressor 200, and improve the performance of the compressor 200.

[0046] As shown in Figures 1 and 2, in some embodiments, exemplarily, along the radial direction of the end plate 120, one end of the second groove segment 132 opposite to the first groove segment 131 passes through the outer peripheral wall 121 of the end plate 120.

[0047] In this embodiment, the end of the second groove segment 132 facing away from the first groove segment 131 is defined to penetrate the outer peripheral wall 121 of the end plate 120 radially. That is, the end of the second groove segment 132 facing away from the first groove segment 131 forms an opening on the outer peripheral wall 121 of the end plate 120. This can further reduce the stiffness of the area of ​​the end plate 120 near the outer peripheral wall 121, increase the elastic deformation of the area of ​​the end plate 120 near the outer peripheral wall 121, improve the buffering effect, and thus effectively improve the wear resistance of the end plate 120 and the end face of the stationary scroll plate 210 during the operation of the compressor 200, reduce wear, and help extend the service life of the compressor 200 and improve the performance of the compressor 200.

[0048] As shown in Figures 1 and 2, in some embodiments, for example, there are multiple second slot segments 132, which 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 segment 131.

[0049] In this embodiment, the number of second slot segments 132 is limited to a plurality. Specifically, the plurality of second slot segments 132 are arranged at intervals along the circumference, and each second slot segment 132 is connected to the first slot segment 131.

[0050] It is understandable that the more second groove segments 132 there are, that is, the more disconnected structures are formed in the area of ​​the end plate 120 located on at least one side of the first groove segment 131 in the radial direction, the better the buffering effect, thereby effectively improving the wear resistance of the end plate 120 and the end face of the stationary scroll plate 210 during the operation of the compressor 200 and reducing wear.

[0051] As shown in Figures 1 and 2, in some embodiments, exemplary, along the radial direction of the end plate 120, the first groove segment 131 includes opposing first groove walls 133 and second groove walls 134, the first groove wall 133 being 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 gap between the first groove wall 133 and the outer peripheral wall 121 of the end plate 120.

[0052] In this embodiment, the first groove segment 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 and the second groove wall 134 are opposite 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, that is, the first groove wall 133 is the outer wall and the second groove wall 134 is the inner wall.

[0053] The first groove wall 133 and the outer peripheral wall 121 of the end plate 120 are radially spaced. That is, the end plate 120 reserves a certain gap between the radial outer side of the first groove section 131 and the outer peripheral wall 121. So that when the end plate 120 is fixed by tooling and fixtures during the manufacturing process of the moving scroll plate 100, the surface reserved at the gap of the end plate 120 can form a supporting surface, which improves the fixing effect of the end plate 120, facilitates the processing and manufacturing of the moving scroll plate 100, improves production efficiency, and helps to reduce the production cost of the moving scroll plate 100.

[0054] This means that the stiffness of the end plate 120 near the outer peripheral wall 121 can be reduced, and the elastic deformation of the end plate 120 and the stationary scroll 210 end face in the axial contact area can be increased. This is beneficial to increase the effective contact area between the end plate 120 and the stationary scroll 210 end face, reduce the contact surface pressure, and thus effectively improve the wear resistance of the end plate 120 and the stationary scroll 210 end face during the operation of the compressor 200, while also being compatible with the use of tooling and fixtures.

[0055] As shown in Figure 1, in some embodiments, the spacing d satisfies 2mm≤d≤10mm.

[0056] In this embodiment, the range of values ​​for the radial distance between the first groove wall 133 and the outer peripheral wall 121 of the end plate 120 is defined.

[0057] Understandably, if the spacing is too small, i.e., less than 2mm, the area of ​​the support surface reserved at the spacing of the end plate 120 will be 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 10mm, the rigidity of the area of ​​the end plate 120 near the outer peripheral wall 121 will be too large, increasing the wear of the contact end surface between the end plate 120 and the stationary scroll 210.

[0058] By limiting the spacing to between 2mm and 10mm, it is possible to ensure the buffering effect of the end plate 120 near the outer peripheral wall 121, while also enabling reliable fixing using tooling and fixtures during the manufacturing of the moving scroll plate 100. This facilitates the manufacturing of the moving scroll plate 100, improves production efficiency, and helps reduce the production cost of the moving scroll plate 100.

[0059] For example, the spacing d satisfies 6mm≤d≤8mm.

[0060] As shown in Figure 1, in some embodiments, exemplarily, along the circumferential direction of the end plate 120, the first groove segment 131 includes a first end 135 and a second end 136 facing away from each other; wherein, along the radial direction of the end plate 120, the line connecting the first end 135 and the central axis 122 of the end plate 120 is a first connecting line 140, and the line connecting the second end 136 and the central axis 122 of the end plate 120 is a second connecting line 150, and the angle α between the first connecting line 140 and the second connecting line 150 satisfies α≥90°.

[0061] In this embodiment, the first groove segment 131 is defined as including a first end 135 and a second end 136 that are circumferentially opposite. Specifically, along the radial direction of the end plate 120, the line connecting the central axis 122 of the end plate 120 and the first end 135 is the first connecting line 140, and the line connecting the central axis 122 of the end plate 120 and the second end 136 is the second connecting line 150. The angle between the first connecting line 140 and the second connecting line 150 is greater than or equal to 90°. That is to say, the angle range of the first groove segment 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 near the outer peripheral wall 121, improving the buffering effect, and further improving the wear resistance of the contact area between the end plate 120 and the end face of the stationary vortex disk 210.

[0062] As shown in Figures 1, 2 and 4, in some embodiments, the moving scroll disk 100, exemplarily, further includes a fixing groove 160. The fixing groove 160 is disposed on the outer peripheral wall 121 of the end plate 120 and extends radially along the end plate 120. Along the axial direction of the end plate 120, the fixing groove 160 is offset from the second groove segment 132.

[0063] In this embodiment, the moving scroll plate 100 further includes a fixing groove 160. Specifically, the fixing groove 160 is disposed on the outer peripheral wall 121 of the end plate 120 and extends radially along the end plate 120. It is understood that during the manufacturing process of the moving scroll plate 100, tooling and fixtures can be used to fix the end plate 120 through the fixing groove 160.

[0064] Along the axial direction of the end plate 120, the fixing groove 160 is staggered from the second groove segment 132. That is to say, at the location of the fixing groove 160, the overall thickness of the end plate 120 is thicker. This can reduce the stiffness of the area of ​​the end plate 120 near the outer peripheral wall 121 while ensuring the structural strength of the area of ​​the end plate 120 near the outer peripheral wall 121, avoiding breakage at this location during the manufacturing process of the moving scroll 100, and improving the yield of the moving scroll 100.

[0065] As shown in Figures 1 and 2, in some embodiments, for example, there are multiple buffer slots 130, which are arranged at intervals along the circumferential direction of the end plate 120.

[0066] In this embodiment, the number of buffer grooves 130 is limited to multiple. Specifically, multiple buffer grooves 130 are arranged at intervals along the circumference of the end plate 120, thereby forming a buffer structure in the entire circumference of the end plate 120 and in the area close to the outer peripheral wall 121. This helps to further improve the buffering effect of the end plate 120 in the area close to the outer peripheral wall 121, increase the elastic deformation of the end plate 120 and the end face of the stationary scroll 210 in the axial direction, increase the effective contact area between the end plate 120 and the end face of the stationary scroll 210, reduce the contact surface pressure, and thus effectively improve the wear resistance of the end plate 120 and the end face of the stationary scroll 210 during the operation of the compressor 200, reduce wear, extend the service life of the compressor 200, and improve the performance of the compressor 200.

[0067] In some embodiments, for example, at least two buffer slots 130 are symmetrically arranged about the central axis 122 of the end plate 120.

[0068] 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, this helps to ensure that the end plate 120 is subjected to balanced forces, which extends the service life of the moving scroll plate 100. At the same time, it also helps to reduce the manufacturing difficulty of the moving scroll plate 100, thereby reducing the production cost of the moving scroll plate 100.

[0069] According to a second aspect of this application, a compressor 200 is provided, including a moving scroll plate 100 as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the moving scroll plate 100, which will not be repeated here.

[0070] As shown in Figure 5, the compressor 200 further includes a stationary scroll plate 210, the stationary scroll teeth 211 of the stationary scroll plate 210 being connected to the moving scroll teeth 110; and a frame 220, located on the side of the end plate 120 away from the moving scroll teeth 110, and connected to the stationary scroll plate 210, for supporting the moving scroll plate 100.

[0071] The compressor 200 provided in this embodiment includes a moving scroll 100, a stationary scroll 210, and a frame 220. Specifically, the stationary scroll teeth 211 of the stationary scroll 210 are connected to the moving scroll teeth 110, thereby forming a compression chamber by the stationary scroll 210 and the moving scroll 100. Exemplarily, the stationary scroll 210 is provided with an exhaust port, which communicates with the compression chamber. Specifically, during the operation of the compressor 200, the crankshaft can drive the moving scroll 100 to rotate relative to the stationary 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.

[0072] The frame 220 is located on the side of the end plate 120 away from the moving worm gear 110, and the frame 220 is connected to the stationary worm gear 210 to support the moving worm gear 100 and ensure the cooperation between the stationary worm gear 210 and the moving worm gear 100.

[0073] Along the axial direction of the end plate 120, the moving worm gear 110 is disposed on one side of the end plate 120, and the buffer groove 130 is disposed on the side of the end plate 120 away from the moving worm gear 110. That is to say, the moving worm gear 110 and the buffer groove 130 are respectively disposed on both sides of the end plate 120 in the axial direction.

[0074] 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 away from each other. The moving scroll gear 110 is located on the first end 135 surface, and the buffer groove 130 is located on the second end 136 surface. It is understood that the first end 135 surface is used for contact and engagement with the end face of the stationary scroll 210. Since the buffer groove 130 is located on the second end 136 surface, it helps to ensure the sealing of the compression cavity formed by the stationary scroll 210 and the moving scroll 100, thus ensuring the reliability of the compressor 200 having the moving scroll 100.

[0075] Understandably, during the operation of the compressor 200, the moving scroll 100 is always in a slightly tilted state, which causes stress concentration between the area of ​​the first end 135 face near the outer peripheral wall 121 of the end plate 120 and the end face of the stationary scroll 210, resulting in increased wear on the end faces of the stationary scroll 210 and the moving scroll 100 that come into contact with each other.

[0076] The buffer groove 130 is located on the side of the end plate 120 facing away from the moving scroll tooth 110 in the axial direction, and the buffer groove 130 is located close to the outer peripheral wall 121 of the end plate 120. That is to say, the thickness of the end plate 120 is reduced near the outer peripheral wall 121, thereby effectively reducing the rigidity of the end plate 120 near the outer peripheral wall 121, increasing the elastic deformation of the end plate 120 and the stationary scroll 210 end face in the axial direction, which is conducive to increasing the effective contact area between the end plate 120 and the stationary scroll 210 end face, reducing the contact surface pressure, and thus effectively improving the wear resistance of the end plate 120 and the stationary scroll 210 end face during the operation of the compressor 200, reducing wear, which is conducive to extending the service life of the compressor 200 and improving the performance of the compressor 200.

[0077] The buffer groove 130 includes a first groove segment 131 and a second groove segment 132, wherein the first groove segment 131 and the second groove segment 132 are connected. Specifically, at least a portion of the first groove segment 131 extends circumferentially along the end plate 120, thereby increasing the area of ​​the buffer region formed by the end plate 120 near the outer peripheral wall 121 and reducing the stiffness of the region of the end plate 120 near the outer peripheral wall 121.

[0078] At least a portion of the second groove segment 132 extends radially along the end plate 120, thereby breaking the continuous structure on the end plate 120 located on at least one side of the first groove segment 131 in the radial direction. This helps to further reduce the stiffness of the area of ​​the end plate 120 near the outer peripheral wall 121, increase the elastic deformation of the area of ​​the end plate 120 near the outer peripheral wall 121, and improve the buffering effect.

[0079] As shown in Figures 3 and 5, in some embodiments, for example, the frame 220 is provided with a thrust surface 221 on the side facing the end plate 120; wherein, along the radial direction of the end plate 120, the distance D1 between the groove wall of the buffer groove 130 near the central axis 122 of the end plate 120 and the central axis 122 of the end plate 120, the distance D2 between the outer edge of the thrust surface 221 and the central axis 122 of the end plate 120, and the circumduction radius R of the moving scroll disk 100 satisfy D1 > D2 + R.

[0080] In this embodiment, the frame 220 is provided with a thrust surface 221. It can be understood that the frame 220 supports the moving scroll 100 through the thrust surface 221.

[0081] The distance between the wall of the buffer groove 130 and the central axis 122 of the end plate 120 in the radial direction is D1, and the distance between the outer edge of the thrust surface 221 and the central axis 122 of the end plate 120 is D2. That is, the radius of the outer circumference of the thrust surface 221 is D2, and the radius of rotation of the moving scroll plate 100 is R. Specifically, D1 is greater than the sum of D2 and R. Thus, during the translational rotation of the moving scroll plate 100 relative to the stationary scroll plate 210, the outer edge of the thrust surface 221 can be effectively prevented from entering the buffer groove 130 and thus wearing against the wall of the buffer groove 130. This is beneficial to further extend the service life of the compressor 200 and ensure the reliable operation of the compressor 200.

[0082] According to a third aspect of this application, a refrigeration device is provided, including a moving scroll plate 100 or a compressor 200 as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the moving scroll plate 100 or the compressor 200, which will not be repeated here.
