Description

Technical Field

[0001] This invention relates to the field of compressor vibration damping technology, and more specifically, to a vibration damping structure, a compressor, and a refrigeration device. Background Technology

[0002] Currently, in refrigerators using related technologies, the bottom plate is designed as an integrated unit, with the compressor directly mounted on it. The vibration generated by the compressor is transmitted directly to the bottom plate through the foot pads, causing fundamental frequency resonance noise in the bottom plate. At the same time, the compressor vibration is transmitted to the interior of the refrigerator (pipes, partitions, etc.) through the bottom plate, resulting in resonance noise. Summary of the Invention

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

[0004] Therefore, a first aspect of the embodiments of the present invention provides a vibration reduction structure.

[0005] A second aspect of the present invention provides a compressor.

[0006] A third aspect of the present invention provides a refrigeration device.

[0007] In view of the above, according to a first aspect of the present invention, a vibration damping structure is provided for a compressor. The compressor includes a foot pad structure. The vibration damping structure includes: a base plate having a through hole; and a vibration damping member disposed on the base plate and located at the through hole. The vibration damping member includes a connecting portion and a damping portion. A first end of the connecting portion is connected to the base plate, and a second end of the connecting portion is connected to the damping portion. Along the thickness direction of the base plate, there is a gap between the damping portion and the through hole. The damping portion has a mounting surface on the side facing away from the through hole, and the mounting surface is used to connect the foot pad structure.

[0008] The vibration damping structure provided in this embodiment of the invention includes a base plate and a vibration damping component. Specifically, the base plate is provided with a through hole, the vibration damping component is disposed at the through hole, and there is a gap between the vibration damping part and the through hole along the thickness direction of the base plate, so that the vibration damping component forms a cantilever spring structure.

[0009] The vibration damping section has a mounting surface on the side opposite to the through hole. Since the mounting surface is connected to the foot pad structure, the cantilever spring structure and the foot pad structure form a two-stage vibration damping system, which can greatly reduce the vibration generated by the compressor during operation. Compared with related technologies that directly mount the compressor on the base plate, this can significantly improve the transmission of the vibration generated by the compressor to the inside of the housing, thereby helping to reduce the vibration noise during the operation of the compressor. At the same time, it can also reduce the possibility of resonance, thereby reducing the fundamental frequency resonance noise during the operation of the compressor, improving the resonance abnormal noise generated during the operation of the refrigeration equipment, and enhancing the user's experience of using the refrigeration equipment.

[0010] In addition, since the damping part is opposite to the through hole along the thickness direction of the base plate, and the foot pad structure is located on the side of the damping part away from the through hole, the damping part has a larger deformation space, which effectively improves the damping effect of the damping structure on the compressor.

[0011] Optionally, the number of connecting parts is one, or the number of connecting parts is at least two, which can be set according to actual needs.

[0012] Optionally, at least a portion of the connecting part extends along the thickness direction of the base plate. Alternatively, at least a portion of the connecting part extends obliquely.

[0013] In addition, the vibration reduction structure provided by the above-described technical solution of the present invention also has the following additional technical features:

[0014] In some technical solutions, the second end of the connector may optionally extend at an angle toward the side where the vibration damping part is located.

[0015] In this technical solution, the second end of the connecting part is defined to extend obliquely to the side where the vibration damping part is located. In other words, the connecting part is an oblique connecting structure, which is beneficial to improving the vibration damping effect of the vibration damping structure on the compressor compared to a straight arm connecting structure.

[0016] In some technical solutions, optionally, there are multiple connecting parts, with at least two connecting parts located on opposite sides of the vibration damping part.

[0017] In this technical solution, the number of connecting parts is limited to multiple. Specifically, at least two connecting parts are located on opposite sides of the vibration damping part, so that at least two connecting parts and the vibration damping part form a spring cantilever structure. This reduces the vibration and noise generated by the compressor during operation while ensuring the support effect of the vibration damping structure on the compressor, which is beneficial to improving the reliability of the refrigeration equipment.

[0018] In some technical solutions, the vibration damping component and the base plate can optionally be an integrated structure.

[0019] In this technical solution, the vibration damping component and the base plate are defined as an integral structure. Optionally, the base plate is stamped to form the vibration damping component and through holes, i.e., a cantilever spring structure. This can greatly reduce the vibration generated by the compressor during operation without adding any parts, and can significantly improve the transmission of the vibration generated by the compressor to the inside of the housing. This helps to reduce the vibration noise during the operation of the compressor. At the same time, it can also reduce the possibility of resonance, thereby reducing the fundamental frequency resonance noise during the operation of the compressor, improving the resonance abnormal noise generated during the operation of refrigeration equipment, and also helping to reduce the production cost of the compressor.

[0020] In addition, the integrated structure facilitates the mass production of vibration damping structures, reduces the manufacturing difficulty of vibration damping structures, and further reduces the manufacturing cost of compressors.

[0021] In some technical solutions, optionally, there are multiple vibration damping components and multiple through holes, with each vibration damping component located at a through hole; wherein, the mounting surface of each vibration damping component is provided with a first connecting hole, and the first connecting hole connects to the foot pad structure.

[0022] In this technical solution, the number of vibration damping components is limited to multiple. Specifically, the number of through holes is also multiple. Each vibration damping component is set at one through hole, and the mounting surface of each vibration damping component is provided with a first connecting hole. The first connecting hole is used to connect the foot pad structure. It can be understood that there are multiple foot pad structures. That is to say, multiple vibration damping components are set on the base plate, and multiple vibration damping components are connected to multiple foot pad structures through multiple first connecting holes, so as to reduce the vibration and noise generated by the compressor during operation.

[0023] In some technical solutions, optionally, there are multiple foot pad structures, and multiple first connecting holes are provided on the mounting surface, with the multiple first connecting holes respectively connecting to multiple foot pad structures.

[0024] In this technical solution, a plurality of first connection holes are provided on the mounting surface. Specifically, the plurality of first connection holes are connected to a plurality of foot pad structures respectively. That is, a vibration damping component is provided on the base plate, and the mounting surface of the vibration damping component is provided with a plurality of first connection holes. The vibration damping component is connected to a plurality of foot pad structures of the compressor through the plurality of first connection holes to reduce the vibration and noise generated by the compressor during operation.

[0025] In some technical solutions, the mounting surface may optionally be circular or quadrilateral in shape; and / or at least a portion of the mounting surface may be constructed as a plane.

[0026] In this technical solution, the mounting surface is either circular or quadrilateral. The specific shape can be chosen according to actual needs.

[0027] At least part of the mounting surface is flat. Since the mounting surface is connected to the foot pad structure, setting at least part of the mounting surface to be flat helps to ensure that the mounting surface and the foot pad structure can fit together after connection, improves the connection strength between the mounting surface and the foot pad structure, and ensures the vibration damping effect of the damping component on the compressor.

[0028] According to a second aspect of the present invention, a compressor is provided, comprising a vibration damping structure as provided by any of the above-described technical solutions, and thus possessing all the beneficial technical effects of the vibration damping structure, which will not be elaborated further here.

[0029] Furthermore, the compressor also includes a foot pad structure that is connected to the mounting surface.

[0030] The compressor provided in this embodiment of the invention includes a vibration damping structure and a foot pad structure. Specifically, the foot pad structure is connected to the mounting surface, thereby forming a two-stage vibration damping system with the cantilever spring structure. This can greatly reduce the vibration generated by the compressor during operation. Compared with related technologies that directly mount the compressor on the base plate, this can significantly improve the transmission of vibration generated by the compressor to the inside of the housing, thereby helping to reduce vibration noise during compressor operation. At the same time, it can also reduce the possibility of resonance, thereby reducing the fundamental frequency resonance noise during compressor operation, improving the resonance noise generated during the operation of refrigeration equipment, and enhancing the user's experience with the refrigeration equipment.

[0031] In addition, since the damping part is opposite to the through hole along the thickness direction of the base plate, and the foot pad structure is located on the side of the damping part away from the through hole, the damping part has a larger deformation space, which effectively improves the damping effect of the damping structure on the compressor.

[0032] Optionally, at least a portion of the foot pad structure includes a flexible element.

[0033] In addition, the vibration reduction structure provided by the above-described technical solution of the present invention also has the following additional technical features:

[0034] In some technical solutions, optionally, the side of the vibration damping part facing the through hole forms a vibration damping space with the through hole, and the vibration damping space communicates with the first connection hole of the mounting surface; the foot pad structure is provided with a second connection hole, and the compressor also includes a fixing component, which passes through the second connection hole and the first connection hole respectively, so that the foot pad structure is connected to the mounting surface, and a part of the fixing component is located in the vibration damping space.

[0035] In this technical solution, the compressor is further defined as including a fixing component. Specifically, the side of the vibration damping part facing the through hole forms a vibration damping space with the through hole, and the vibration damping space is connected to the first connecting hole. The fixing component passes through the second connecting hole and the first connecting hole respectively, so that the foot pad structure is connected to the mounting surface, thereby achieving the function of fixing the entire compressor.

[0036] Since some of the fixed components are located within the vibration damping space, interference between the fixed components and other structures due to deformation of the vibration damping part can be effectively reduced during compressor operation, which helps to further improve the reliability of the refrigeration equipment.

[0037] In some technical solutions, the fixing component optionally includes a bushing and a fastener, wherein the bushing passes through the second connecting hole and the first connecting hole respectively, a portion of the bushing is located within the vibration damping space, and the fastener is disposed on the bushing to connect the foot pad structure to the mounting surface, a portion of the fastener being located within the vibration damping space; the central axis of the first connecting hole coincides with the central axis of the second connecting hole.

[0038] In this technical solution, the fixing component is further defined as a bushing and a fastener. Specifically, the bushing passes through the second connecting hole and the first connecting hole in sequence, and the fastener is set on the bushing. That is, the bushing is locked by the fastener so that the foot pad structure is connected to the mounting surface, thereby achieving the function of fixing the entire compressor.

[0039] Since part of the bushing and part of the fastener are located within the vibration damping space, interference between the fastener or bushing and other structures due to deformation of the vibration damping part can be effectively reduced during compressor operation.

[0040] The central axis of the first connecting hole coincides with the central axis of the second connecting hole, that is, the axis of the first connecting hole and the foot pad structure are aligned, which helps to ensure the connection effect between the foot pad structure and the mounting surface and improves the reliability of the compressor and refrigeration equipment.

[0041] Optionally, fasteners include screws.

[0042] Optionally, if there are multiple first connection holes, there are also multiple foot pad structures, multiple bushings and fasteners, and they correspond one-to-one.

[0043] According to a third aspect of the present invention, a refrigeration device is provided, comprising a vibration damping structure or compressor as provided in any of the above technical solutions, and thus possessing all the beneficial technical effects of the vibration damping structure or compressor, which will not be elaborated further here.

Detailed Implementation

[0053] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0054] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0055] The following reference Figures 1 to 5 This describes a vibration damping structure 100, a compressor 200, and a refrigeration device provided according to some embodiments of the present invention.

[0056] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a vibration damping structure 100 is proposed for use in a compressor 200. The compressor 200 includes a foot pad structure 210. The vibration damping structure 100 includes: a base plate 110 with a through hole 111; and a vibration damping member 120 disposed on the base plate 110 and located at the through hole 111. The vibration damping member 120 includes a connecting part 122 and a damping part 121. The first end 123 of the connecting part 122 is connected to the base plate 110, and the second end 124 of the connecting part 122 is connected to the damping part 121. Along the thickness direction of the base plate 110, there is a gap between the damping part 121 and the through hole 111. The side of the damping part 121 facing away from the through hole 111 is provided with a mounting surface 125 for connecting the foot pad structure 210.

[0057] The vibration damping structure 100 provided in this embodiment of the invention includes a base plate 110 and a vibration damping member 120. Specifically, the base plate 110 is provided with a through hole 111, and the vibration damping member 120 is disposed at the through hole 111. Along the thickness direction of the base plate 110, there is a gap between the vibration damping part 121 and the through hole 111, so that the vibration damping member 120 forms a cantilever spring structure.

[0058] The vibration damping part 121 has a mounting surface 125 on the side opposite to the through hole 111. Since the mounting surface 125 is connected to the foot pad structure 210, the cantilever spring structure and the foot pad structure 210 form a two-stage vibration damping system, which can greatly reduce the vibration generated by the compressor 200 during operation. Compared with the related technology of directly mounting the compressor on the base plate, it can significantly improve the transmission of the vibration generated by the compressor 200 to the inside of the housing, thereby helping to reduce the vibration noise during the operation of the compressor 200. At the same time, it can also reduce the possibility of resonance, thereby reducing the fundamental frequency resonance noise during the operation of the compressor 200, improving the resonance abnormal noise generated during the operation of the refrigeration equipment, and improving the user's experience of using the refrigeration equipment.

[0059] Furthermore, since the damping part 121 is opposite to the through hole 111 along the thickness direction of the base plate 110, and the foot pad structure 210 is located on the side of the damping part 121 away from the through hole 111, the damping part 121 has a larger deformation space, which effectively improves the damping effect of the damping structure 100 on the compressor 200.

[0060] Optionally, the number of connecting parts 122 is one, or the number of connecting parts 122 is at least two, which can be set according to actual needs.

[0061] Optionally, at least a portion of the connecting portion 122 extends along the thickness direction of the base plate 110. Alternatively, at least a portion of the connecting portion 122 extends obliquely.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the second end 124 of the connecting portion 122 extends obliquely toward the side where the vibration damping portion 121 is located.

[0063] In this embodiment, the second end 124 of the connecting portion 122 is defined to extend obliquely to the side where the vibration damping portion 121 is located. That is, the connecting portion 122 is an oblique connecting structure, which is beneficial to improving the vibration damping effect of the vibration damping structure 100 on the compressor 200 compared to the connecting portion 122 being a straight arm connecting structure.

[0064] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, there are multiple connecting portions 122, with at least two connecting portions 122 located on opposite sides of the vibration damping portion 121.

[0065] In this embodiment, the number of connecting parts 122 is limited to a plurality. Specifically, at least two connecting parts 122 are located on opposite sides of the vibration damping part 121, thereby forming a spring cantilever structure with the vibration damping part 121. This reduces the vibration and noise generated by the compressor 200 during operation while ensuring the support effect of the vibration damping structure 100 on the compressor 200, which is beneficial to improving the reliability of the refrigeration equipment.

[0066] In some embodiments, the damper 120 and the base plate 110 are optionally integrated.

[0067] In this embodiment, the vibration damper 120 and the base plate 110 are defined as an integral structure. Optionally, the base plate 110 is stamped to form the vibration damper 120 and the through hole 111, i.e., the cantilever spring structure. This can greatly reduce the vibration generated by the compressor 200 during operation without adding any parts, and can significantly improve the transmission of the vibration generated by the compressor 200 to the inside of the housing. This is beneficial to reducing the vibration noise during the operation of the compressor 200. At the same time, it can also reduce the possibility of resonance, thereby reducing the fundamental frequency resonance noise during the operation of the compressor 200, improving the resonance abnormal noise generated during the operation of the refrigeration equipment, and also helping to reduce the production cost of the compressor 200.

[0068] In addition, the integrated structure facilitates the mass production of the vibration damping structure 100, reduces the manufacturing difficulty of the vibration damping structure 100, and further reduces the manufacturing cost of the compressor 200.

[0069] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, there are multiple vibration damping elements 120 and multiple through holes 111, with each vibration damping element 120 located at a through hole 111; wherein, the mounting surface 125 of each vibration damping element 120 is provided with a first connecting hole 130, and the first connecting hole 130 connects to the foot pad structure 210.

[0070] In this embodiment, the number of vibration damping elements 120 is limited to multiple. Specifically, the number of through holes 111 is also multiple. Each vibration damping element 120 is disposed at one through hole 111, and the mounting surface 125 of each vibration damping element 120 is provided with a first connecting hole 130. The first connecting hole 130 is used to connect the foot pad structure 210. It can be understood that there are multiple foot pad structures 210. That is to say, multiple vibration damping elements 120 are disposed on the base plate 110, and multiple vibration damping elements 120 are connected to multiple foot pad structures 210 through multiple first connecting holes 130 respectively, so as to reduce the vibration and noise generated by the compressor 200 during operation.

[0071] like Figure 3 As shown, in some embodiments, optionally, there are multiple foot pad structures 210, and multiple first connection holes 130 are provided on the mounting surface 125, with the multiple first connection holes 130 respectively connecting to multiple foot pad structures 210.

[0072] In this embodiment, a plurality of first connection holes 130 are provided on the mounting surface 125. Specifically, the plurality of first connection holes 130 are respectively connected to a plurality of foot pad structures 210. That is, a vibration damping member 120 is provided on the base plate 110, and the mounting surface 125 of the vibration damping member 120 is provided with a plurality of first connection holes 130. The vibration damping member 120 is connected to the plurality of foot pad structures 210 of the compressor 200 through the plurality of first connection holes 130 to reduce the vibration and noise generated by the compressor 200 during operation.

[0073] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the mounting surface 125 may optionally be circular or quadrilateral in shape; and / or at least a portion of the mounting surface 125 may be configured as a plane.

[0074] In this embodiment, the mounting surface 125 is specifically circular or quadrilateral. The specific shape can be configured according to actual needs.

[0075] At least a portion of the mounting surface 125 is flat. Since the mounting surface 125 is connected to the foot pad structure 210, setting at least a portion of the mounting surface 125 as flat helps to ensure that the mounting surface 125 and the foot pad structure 210 can fit together after being connected, thereby improving the connection strength between the mounting surface 125 and the foot pad structure 210 and ensuring the vibration damping effect of the vibration damping component 120 on the compressor 200.

[0076] According to a second aspect of the present invention, a compressor 200 is provided, including a vibration damping structure 100 as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the vibration damping structure 100, which will not be repeated here.

[0077] like Figure 4 and Figure 5 As shown, the compressor 200 further includes a foot pad structure 210, which is connected to the mounting surface 125.

[0078] The compressor 200 provided in this embodiment of the invention includes a vibration damping structure 100 and a foot pad structure 210. Specifically, the foot pad structure 210 is connected to the mounting surface 125, thereby forming a two-stage vibration damping system with the cantilever spring structure and the foot pad structure 210. This can greatly reduce the vibration generated by the compressor 200 during operation. Compared with related technologies where the compressor is directly mounted on the base plate, this can significantly improve the transmission of vibration generated by the compressor 200 to the inside of the housing, thereby helping to reduce the vibration noise during the operation of the compressor 200. At the same time, it can also reduce the possibility of resonance, thereby reducing the fundamental frequency resonance noise during the operation of the compressor 200, improving the resonance noise generated during the operation of the refrigeration equipment, and enhancing the user's experience of using the refrigeration equipment.

[0079] Furthermore, since the damping part 121 is opposite to the through hole 111 along the thickness direction of the base plate 110, and the foot pad structure 210 is located on the side of the damping part 121 away from the through hole 111, the damping part 121 has a larger deformation space, which effectively improves the damping effect of the damping structure 100 on the compressor 200.

[0080] Optionally, at least a portion of the foot pad structure 210 includes a flexible element.

[0081] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the side of the damping part 121 facing the through hole 111 forms a damping space 140 with the through hole 111, and the damping space 140 communicates with the first connection hole 130 of the mounting surface 125; the foot pad structure 210 is provided with a second connection hole 211, and the compressor 200 also includes a fixing component 240, which passes through the second connection hole 211 and the first connection hole 130 respectively, so that the foot pad structure 210 is connected to the mounting surface 125, and a part of the fixing component 240 is located in the damping space 140.

[0082] In this embodiment, the compressor 200 is further defined as including a fixing component 240. Specifically, the side of the damping part 121 facing the through hole 111 forms a damping space 140 with the through hole 111, and the damping space 140 communicates with the first connecting hole 130. The fixing component 240 passes through the second connecting hole 211 and the first connecting hole 130 respectively, so that the foot pad structure 210 is connected to the mounting surface 125, thereby achieving the function of fixing the entire compressor 200.

[0083] Since some of the fixed components 240 are located within the vibration damping space 140, during the operation of the compressor 200, the interference between the fixed components 240 and other structures caused by the deformation of the vibration damping part 121 can be effectively reduced, which is conducive to further improving the reliability of the refrigeration equipment.

[0084] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the fixing component 240 includes a bushing 220 and a fastener 230, wherein the bushing 220 passes through the second connecting hole 211 and the first connecting hole 130 respectively, a portion of the bushing 220 is located within the vibration damping space 140, and the fastener 230 is disposed on the bushing 220 to connect the foot pad structure 210 to the mounting surface 125, a portion of the fastener 230 is located within the vibration damping space 140; the central axis of the first connecting hole 130 coincides with the central axis of the second connecting hole 211.

[0085] In this embodiment, the fixing component 240 is defined to include a bushing 220 and a fastener 230. Specifically, the bushing 220 passes through the second connecting hole 211 and the first connecting hole 130 in sequence, and the fastener 230 is disposed on the bushing 220. That is, the bushing 220 is locked by the fastener 230 so that the foot pad structure 210 is connected to the mounting surface 125, thereby achieving the function of fixing the entire compressor 200.

[0086] Since a portion of the bushing 220 and a portion of the fastener 230 are both located within the vibration damping space 140, during the operation of the compressor 200, the interference between the fastener 230 or the bushing 220 and other structures caused by the deformation of the vibration damping part 121 can be effectively reduced.

[0087] The central axis of the first connecting hole 130 coincides with the central axis of the second connecting hole 211, that is, the axis of the first connecting hole 130 and the foot pad structure 210 are aligned, which helps to ensure the connection effect between the foot pad structure 210 and the mounting surface 125 and improves the reliability of the compressor 200 and the refrigeration equipment.

[0088] Optionally, fastener 230 includes screws.

[0089] Optionally, if there are multiple first connection holes 130, there are also multiple foot pad structures 210, multiple bushings 220 and multiple fasteners 230, and they correspond one-to-one.

[0090] According to a third aspect of the present invention, a refrigeration device is provided, comprising a vibration damping structure 100 or a compressor 200 as provided in any of the above embodiments, and thus possessing all the beneficial technical effects of the vibration damping structure 100 or the compressor 200, which will not be elaborated further here.
