Description

Technical Field

[0001] This invention relates to the field of compressor technology, and more specifically, to a foot pad assembly, a compressor, and a refrigeration device. Background Technology

[0002] As the core component of a refrigerator system, the compressor is typically mounted on the base of the refrigerator system via feet. The vibrations generated by the compressor during operation are transmitted to the base through these feet. Currently, compressor feet are usually made of rubber. During compressor operation, the absorption and release of vibration energy by the rubber feet depends on their flexibility and hardness. Lower hardness results in stronger vibration damping. However, since the compressor's weight is entirely supported by the rubber feet, overly soft rubber feet can deform or even collapse during long-term refrigerator operation, thus reducing their vibration damping effect.

[0003] Therefore, designing a foot pad assembly that can improve shock absorption has become an urgent problem to be solved. Summary of the Invention

[0004] The present invention aims to at least solve the problem of poor vibration damping effect on compressors.

[0005] Therefore, a first aspect of the present invention provides a foot pad assembly.

[0006] A second aspect of the present invention provides a compressor.

[0007] A third aspect of the present invention provides a refrigeration device.

[0008] In view of this, a first aspect of the present invention provides a foot pad assembly, comprising: a first elastic member having a first receiving cavity; a second elastic member disposed within the first receiving cavity and conforming to the inner wall of the first receiving cavity; and a support portion disposed on the first elastic member or the second elastic member for supporting a supported object; wherein when the support portion supports the supported object, the first elastic member and the second elastic member are capable of elastic deformation, and the elastic deformation of the first elastic member and the second elastic member are different.

[0009] The foot pad assembly provided by this invention includes a first elastic member and a second elastic member. The first elastic member has a first receiving cavity, so that the second elastic member can be disposed within the first receiving cavity and fit against the inner wall of the first receiving cavity. It is understood that the first and second elastic members are similarly nested, with the first elastic member disposed on the outer side and the second elastic member disposed on the inner side. When the support portion is under force supporting the supported object, vibration damping can be achieved through the first and second elastic members, thereby preventing the supported object from being damaged by strong vibrations. Because the first and second elastic members can undergo elastic deformation along the direction of force when subjected to force, and the elastic deformation produced by the first and second elastic members is different, a small displacement will occur between the first and second elastic members. That is, one of the first and second elastic members will undergo elastic deformation first, thus generating a small friction between the two elastic members, thereby dissipating the vibration energy and improving the vibration damping effect. It is understood that because the vibration frequency is high, the number of friction cycles between the two elastic members is also relatively high, thus utilizing the friction between the two elastic members can effectively reduce vibration energy. Compared to related technologies where the elastic components of the foot pad assembly are all one-piece structures or have reinforced structures, this application utilizes the friction generated by the mutual movement between two objects, so that the vibration energy is reduced through frictional resistance, effectively reducing the vibration energy.

[0010] Meanwhile, since the support portion is placed on the first elastic member or the second elastic member in this application, it can be ensured that one of the first elastic member and the second elastic member bears the force generated by vibration first, thereby ensuring that one of the first elastic member and the second elastic member undergoes elastic deformation first. In this way, a small displacement can be generated relative to the other of the first elastic member and the second elastic member, thereby achieving friction reduction of vibration energy.

[0011] The foot pad assembly provided by the present invention may also have the following additional technical features:

[0012] In some embodiments, the supported object may optionally include a compressor.

[0013] In some embodiments, the hardness of the first elastic element may be greater than the hardness of the second elastic element.

[0014] In this embodiment, the hardness of the first elastic element is greater than that of the second elastic element. Thus, when the first elastic element undergoes a certain degree of elastic deformation under stress, it can cause the more flexible second elastic element to undergo elastic deformation, which is more conducive to reducing vibration energy.

[0015] In some embodiments, the second elastic member may optionally include a second receiving cavity, and the foot pad assembly may further include a fixing member disposed within the second receiving cavity for fixing the first elastic member and the second elastic member in the installation position.

[0016] In this embodiment, the second elastic element includes a second receiving cavity. The foot pad assembly includes a fixing member. This allows the fixing member to be disposed within the second receiving cavity and pass through both the second and first receiving cavities, thereby securing the first and second elastic elements in their mounting positions using the second fixing member, improving the installation stability of the foot pad assembly. Furthermore, since the fixing member is disposed within the second receiving cavity, it can also be used to strengthen the second elastic element, thereby improving its stability.

[0017] In some embodiments, the first receiving cavity may optionally include: a first hole segment and a second hole segment, the inner diameter of the first hole segment being larger than the inner diameter of the second hole segment, and the inner wall of the second hole segment abutting against the outer wall of the peripheral side of the fastener; the outer wall of the fastener and the inner wall of the first hole segment form an installation space, and the second elastic member is disposed within the installation space.

[0018] In this embodiment, the first receiving cavity includes a first hole segment and a second hole segment. The inner diameter of the first hole segment is larger than the inner diameter of the second hole segment; that is, the first receiving cavity is formed as a stepped hole. When the fastener is installed in the second receiving cavity, the inner wall of the second hole segment abuts against the outer wall of the fastener's periphery; that is, part of the fastener extends out of the second receiving cavity and is disposed within the second hole segment. Since the inner diameter of the first hole segment is larger than the inner diameter of the second hole segment, when the inner wall of the second hole segment abuts against the outer wall of the fastener's periphery, an installation space is formed between the inner wall of the first hole segment and the outer wall of the fastener, and the second elastic element can be disposed within the installation space. It is understood that defining the installation space facilitates the placement of the second elastic element. For example, liquid material can be injected into the installation space using injection molding, and the second elastic element can be formed after solidification. This is more conducive to forming second elastic elements of various shapes, thereby maximizing the fulfillment of force requirements in practical applications.

[0019] In some embodiments, the second elastic element may optionally be an injection molded part whose shape is adapted to the shape of the installation space.

[0020] In this embodiment, the second elastic element can be configured as an injection-molded part. Injection-molded parts are easy to process, convenient to install, and highly flexible in design, capable of forming structures of various shapes, thus maximizing the fulfillment of practical application requirements.

[0021] In some embodiments, the fixing member may optionally include: a fixing sleeve disposed within the second receiving cavity; and a fixing screw disposed within the fixing sleeve.

[0022] In this embodiment, the fixing member includes a fixing sleeve and a fixing screw. The fixing sleeve is disposed within the second receiving cavity and can constrain the first elastic member and the second elastic member in the radial direction of the fixing sleeve to limit the movement of the first elastic member and the second elastic member. The fixing screw is disposed within the fixing sleeve, so that the fixing screw can pass through the fixing sleeve to fix the first elastic member and the second elastic member in the installation position.

[0023] In some embodiments, optionally, along the first direction, the length of the first elastic member and the length of the second elastic member are both less than the length of the fixed sleeve, and one end of the fixed sleeve extends out of the first receiving cavity and the second receiving cavity.

[0024] In this embodiment, along the first direction, the length of the first elastic member and the length of the second elastic member are less than the length of the fixed sleeve, and one end of the fixed sleeve extends out of the first and second receiving cavities. That is, the fixed sleeve needs to protrude from the first and second elastic members. In this way, when fixed with a fixing screw, the fixed sleeve can be used to limit the movement and prevent the force generated by the fixing screw from acting on the first and second elastic members, thus ensuring the elasticity of the first and second elastic members.

[0025] In some embodiments, the extension length of the fixing sleeve is optionally greater than or equal to 0.2 mm.

[0026] In this embodiment, the protruding length of the fixing sleeve is greater than or equal to 0.2 mm. This design ensures that the force generated when the fixing screw is tightened does not act on the first and second elastic elements, and also avoids material waste, thereby reducing costs.

[0027] In some embodiments, the extension length of the retaining sleeve is optionally 0.2 mm.

[0028] In some embodiments, the extension length of the retaining sleeve is optionally 0.4 mm.

[0029] In some embodiments, the extension length of the retaining sleeve is optionally 0.6 mm.

[0030] In some embodiments, optionally, a support portion is disposed on the first elastic member, the support portion including: a support groove disposed on the periphery of the outer surface of the first elastic member, for cooperating with the supported object to support the supported object.

[0031] In this embodiment, a support portion is disposed on the first elastic member, and the support portion may be a support groove. The support groove is disposed on the periphery of the outer surface of the first elastic member and can cooperate with the supported object to support the supported object. Specifically, a mounting hole can be provided on the supported object, and then the support groove can be inserted into the mounting hole to fix the foot pad assembly to the supported object.

[0032] In some embodiments, optionally, the second receiving cavity includes a first through hole and a second through hole, the first through hole communicating with the second through hole; the second elastic member includes: a first elastic portion, the first through hole being disposed on the first elastic portion; a second elastic portion, disposed within the first through hole, and the second through hole being disposed on the second elastic portion; an annular rib for connecting the second elastic portion and the first elastic portion; the first elastic member includes: a fixing groove, disposed on the inner wall of the first receiving cavity, the first elastic portion and the annular rib being disposed within the fixing groove.

[0033] In this embodiment, the second elastic element includes a first elastic portion, a second elastic portion, and an annular rib. A first through hole is provided on the first elastic portion, and the second elastic portion is disposed within the first through hole, thereby allowing the annular rib to connect the first and second elastic portions. The second through hole is located on the second elastic portion. The first elastic element includes a fixing groove. The fixing groove is disposed on the inner wall of the first receiving cavity, and the first elastic portion and the annular rib are disposed within the fixing groove. This arrangement, by providing the second elastic portion and the annular rib within the fixing groove of the first receiving cavity, makes the second elastic element more stable, especially when the foot pad assembly is deformed under force, ensuring the stability of the combined use of the first and second elastic elements.

[0034] The specific shape of the first elastic part can be set according to actual needs.

[0035] In some embodiments, the annular rib is optionally connected to the outer periphery of the second elastic portion and is disposed near one end of the second elastic portion.

[0036] In this embodiment, the annular rib is connected to the outer periphery of the second elastic portion and is disposed near one end of the second elastic portion, that is, the first elastic portion is disposed near one end of the second elastic portion.

[0037] In some embodiments, optionally, the second elastic member extends out of the first receiving cavity, and the support portion is disposed on the portion of the second elastic member extending out of the first receiving cavity.

[0038] In this embodiment, the second elastic element extends out of the first receiving cavity. This allows the support portion to be positioned on the portion of the second elastic element extending out of the first receiving cavity, so that the vibration generated by the compressor is first transmitted to the second elastic element, and then the second elastic element drives the first elastic element to vibrate. This allows the second and first elastic elements to generate minute friction during vibration, thereby reducing vibration energy.

[0039] A second aspect of the invention provides a compressor comprising: a foot pad assembly as described in any of the first aspects.

[0040] The compressor provided by the present invention includes the foot pad assembly as described in any of the first aspects. Since the compressor includes the foot pad assembly as described in any of the first aspects, the compressor provided by this application also possesses all the beneficial technical effects of the foot pad assembly as described in any of the first aspects, which will not be elaborated upon here.

[0041] A third aspect of the present invention provides a refrigeration device comprising: a foot pad assembly as described in any of the technical solutions of the first aspect; and / or a compressor as described in the technical solutions of the second aspect.

[0042] The refrigeration device provided by the present invention includes the foot pad assembly of any of the first aspects; and / or the compressor of the second aspect. Since the refrigeration device includes the foot pad assembly of any of the first aspects and / or the compressor of the second aspect, the refrigeration device provided by this application also possesses all the beneficial technical effects of the foot pad assembly of any of the first aspects and / or the compressor of the second aspect, which will not be elaborated further here.

Detailed Implementation

[0056] 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.

[0057] 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.

[0058] The following reference Figures 1 to 9 The invention describes a foot pad assembly, a compressor, and a refrigeration device according to some embodiments of the invention.

[0059] According to an embodiment of the first aspect of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9As shown, a first aspect of the present invention provides a foot pad assembly 1, including a first elastic member 10 and a second elastic member 12. The first elastic member 10 has a first receiving cavity 100. The second elastic member 12 is disposed within the first receiving cavity 100 and is fitted against the inner wall of the first receiving cavity 100. A support portion 102 is disposed on the first elastic member 10 or the second elastic member 12 for supporting a supported object; when the support portion 102 supports the supported object, the first elastic member 10 and the second elastic member 12 can undergo elastic deformation, and the elastic deformation of the first elastic member 10 and the second elastic member 12 is different.

[0060] The foot pad assembly 1 provided by the present invention includes a first elastic element 10 and a second elastic element 12. The first elastic element 10 has a first receiving cavity 100, so that the second elastic element 12 can be disposed within the first receiving cavity 100 and fit against the inner wall of the first receiving cavity 100. It can be understood that the first elastic element 10 and the second elastic element 12 are similarly nested, with the first elastic element 10 disposed on the outer side and the second elastic element 12 disposed on the inner side. When the support portion 102 is subjected to force to support the supported object, vibration damping can be achieved through the first elastic element 120 and the second elastic element 122, thereby preventing the supported object from being damaged by strong vibration. Because the first elastic element 10 and the second elastic element 12 can undergo elastic deformation along the direction of the force when subjected to force, and the elastic deformation of the first elastic element 10 and the second elastic element 12 is different, a small displacement will occur between the first elastic element 10 and the second elastic element 12. That is, one of the first elastic element 10 and the second elastic element 12 will undergo elastic deformation first, which will generate a small friction between the two elastic elements, thereby dissipating the vibration energy and improving the vibration reduction effect. It can be understood that because the vibration frequency is high, the number of frictions between the two elastic elements is also relatively high, so the friction between the two elastic elements can effectively reduce the vibration energy. Compared with the related technology where the elastic elements of the foot pad assembly 1 are all one-piece structures or have reinforced structures, this application utilizes the friction generated by the mutual movement between two objects, so that the vibration energy is reduced by frictional resistance, effectively reducing the vibration energy.

[0061] Meanwhile, since the support part 102 is disposed on the first elastic member 10 or the second elastic member 12 in this application, it can be ensured that one of the first elastic member 10 and the second elastic member 12 bears the force generated by vibration first, thereby ensuring that one of the first elastic member 10 and the second elastic member 12 undergoes elastic deformation first. In this way, a small displacement can be generated relative to the other of the first elastic member 10 and the second elastic member 12, thereby achieving friction reduction of vibration energy.

[0062] In some embodiments, the supported object may optionally include compressor 2.

[0063] In some embodiments, the hardness of the first elastic element 10 may be greater than the hardness of the second elastic element 12.

[0064] In this embodiment, the hardness of the first elastic element 10 is greater than that of the second elastic element 12. Thus, when the first elastic element 10 undergoes a certain degree of elastic deformation under stress, it can cause the more flexible second elastic element 12 to undergo elastic deformation, which is more conducive to reducing vibration energy.

[0065] In some embodiments, the second elastic member 12 may optionally include a second receiving cavity 126, and the foot pad assembly 1 may further include a fixing member 14 disposed within the second receiving cavity 126 for fixing the first elastic member 10 and the second elastic member 12 to the installation position.

[0066] In this embodiment, the second elastic member 12 includes a second receiving cavity 126. The foot pad assembly 1 includes a fixing member 14. This allows the fixing member 14 to be disposed within the second receiving cavity 126 and pass through both the second receiving cavity 126 and the first receiving cavity 100, thereby securing the first elastic member 10 and the second elastic member 12 in their installation positions using the second fixing member 14, thus improving the installation stability of the foot pad assembly 1. Furthermore, since the fixing member 14 is disposed within the second receiving cavity 126, it can also be used to strengthen the second elastic member 12, thereby improving the stability of the second elastic member 12.

[0067] In some embodiments, the first receiving cavity 100 may optionally include: a first hole segment 1000 and a second hole segment 1002, wherein the inner diameter of the first hole segment 1000 is larger than the inner diameter of the second hole segment 1002, and the inner wall of the second hole segment 1002 abuts against the outer wall of the peripheral side of the fixing member 14; the outer wall of the fixing member 14 and the inner wall of the first hole segment 1000 form an installation space 104, and the second elastic member 12 is disposed in the installation space 104.

[0068] In this embodiment, the first receiving cavity 100 includes a first hole segment 1000 and a second hole segment 1002. The inner diameter of the first hole segment 1000 is larger than the inner diameter of the second hole segment 1002, that is, the first receiving cavity 100 is formed as a stepped hole. When the fastener 14 is installed in the second receiving cavity 126, the inner wall of the second hole segment 1002 abuts against the outer wall of the peripheral side of the fastener 14, that is, a portion of the fastener 14 extends out of the second receiving cavity 126 and is disposed within the second hole segment 1002. Since the inner diameter of the first hole segment 1000 is larger than the inner diameter of the second hole segment 1002, when the inner wall of the second hole segment 1002 abuts against the outer wall of the peripheral side of the fastener 14, an installation space 104 is formed between the inner wall of the first hole segment 1000 and the outer wall of the fastener 14, and the second elastic member 12 can be disposed within the installation space 104. It is understandable that defining the installation space 104 facilitates the setting of the second elastic element 12. For example, liquid material can be injected into the installation space 104 by injection molding, and the second elastic element 12 is formed after solidification. This is more conducive to forming second elastic elements 12 of various shapes, so as to maximize the satisfaction of force requirements in practical applications.

[0069] In specific implementation, such as Figure 3 As shown, the fixing sleeve 140 can be installed in the first receiving cavity 100 first. After the fixing sleeve 140 and the first elastic member 10 are engaged, a closed installation space 104 is formed. Liquid silicone rubber can be injected into the closed installation space 104 through the opening above the first elastic member 10. After the liquid silicone rubber solidifies, a second elastic member 12 is formed in the installation space 104. The second elastic member 12 is not bonded to the inner wall of the cavity. Therefore, there will be a small displacement between the first elastic member 10 and the second elastic member 12. The vibration energy generated when the compressor 2 is running can be dissipated through the small displacement between the first elastic member 10 and the second elastic member 12.

[0070] In some embodiments, the second elastic member 12 is optionally an injection molded part whose shape is adapted to the shape of the mounting space 104.

[0071] In this embodiment, the second elastic element 12 can be configured as an injection-molded part. Injection-molded parts are easy to process, convenient to set up, and highly flexible in design, capable of forming structures of various shapes, thus maximizing the fulfillment of practical application requirements.

[0072] In some embodiments, the fixing member 14 may optionally include: a fixing sleeve 140 disposed within the second receiving cavity 126; and a fixing screw 142 disposed within the fixing sleeve 140.

[0073] In this embodiment, the fixing member 14 includes a fixing sleeve 140 and a fixing screw 142. The fixing sleeve 140 is disposed within the second receiving cavity 126 and can constrain the first elastic member 10 and the second elastic member 12 in the radial direction of the second receiving cavity 126 to limit the first elastic member 10 and the second elastic member 12. The fixing screw 142 is disposed within the fixing sleeve 140, so that the fixing screw 142 can pass through the fixing sleeve 140 to fix the first elastic member 10 and the second elastic member 12 in the installation position.

[0074] like Figure 8 and Figure 9 As shown, the lower end face of the fixing screw 142 contacts the upper end face of the fixing sleeve 140. After the fixing screw 142 is tightened on the refrigerator bottom plate 3, it fixes the fixing sleeve 140 to the bottom plate of the refrigerator. The top of the fixing sleeve 140 is 0.2mm higher than the top of the first elastic member 10 and the second elastic member 12, ensuring that the screw does not directly contact the first elastic member 10 and the second elastic member 12 after tightening, and that the fixing screw 142 does not exert vertical pressure on the foot pad assembly 1. Figure 9 As can be seen, the fixing screw 142 does not directly lock the foot pad assembly 1. The fixing screw 142 only serves to lock the fixing sleeve 140. The fixing sleeve 140 provides horizontal constraint on the first elastic element 10 and the second elastic element 12, but has no vertical constraint effect on the first elastic element 10 and the second elastic element 12.

[0075] In some embodiments, optionally, along the first direction, the length of the first elastic member 10 and the length of the second elastic member 12 are both less than the length of the fixed sleeve 140, and one end of the fixed sleeve 140 extends out of the first receiving cavity 100 and the second receiving cavity 126.

[0076] In this embodiment, along the first direction, the length of the first elastic member 10 and the length of the second elastic member 12 are less than the length of the fixing sleeve 140, and one end of the fixing sleeve 140 extends out of the first receiving cavity 100 and the second receiving cavity 126. That is, the fixing sleeve 140 needs to protrude from the first elastic member 10 and the second elastic member 12. In this way, when the fixing screw 142 is used for fixing, the fixing sleeve 140 can be used for limiting, avoiding the force generated by the fixing screw 142 from acting on the first elastic member 10 and the second elastic member 12, thus ensuring the elasticity of the first elastic member 10 and the second elastic member 12.

[0077] In some embodiments, the extension length of the retaining sleeve 140 is optionally greater than or equal to 0.2 mm.

[0078] In this embodiment, the extension length of the fixing sleeve 140 is greater than or equal to 0.2 mm. This arrangement ensures that the force generated when the fixing screw 142 is fixed does not act on the first elastic element 10 and the second elastic element 12, and also avoids material waste, thereby reducing costs.

[0079] In some embodiments, the extension length of the retaining sleeve 140 is optionally 0.2 mm.

[0080] In some embodiments, the extension length of the retaining sleeve 140 is optionally 0.4 mm.

[0081] In some embodiments, the extension length of the retaining sleeve 140 is optionally 0.6 mm.

[0082] In some embodiments, optionally, a support portion 102 is disposed on the first elastic member 10, and the support portion 102 includes a support groove 1020 disposed on the periphery of the outer surface of the first elastic member 10 for cooperating with the supported object to support the supported object.

[0083] In this embodiment, a support portion 102 is disposed on the first elastic member 10, and the support portion 102 may be a support groove 1020. The support groove 1020 is disposed on the periphery of the outer surface of the first elastic member 10 and can cooperate with the supported object to support the supported object. Specifically, a mounting hole can be provided on the supported object, and then the support groove 1020 can be inserted into the mounting hole to fix the foot pad assembly 1 to the supported object.

[0084] like Figure 9 As shown, the base 20 of the compressor 2 is directly mounted on the support groove 1020. The vibration generated when the compressor 2 is running is attenuated by the foot pad assembly 1 and then transmitted to the refrigerator bottom plate 3.

[0085] In some embodiments, optionally, the second receiving cavity 126 includes a first through hole 1260 and a second through hole 1262, the first through hole 1260 communicating with the second through hole 1262; the second elastic member 12 includes: a first elastic portion 120, the first through hole 1260 being disposed on the first elastic portion 120; a second elastic portion 122, disposed within the first through hole 1260, and the second through hole 1262 being disposed on the second elastic portion 122; and an annular rib 124 for connecting the second elastic portion 122 and the first elastic portion 120; the first elastic member 10 includes: a fixing groove 106, disposed on the inner wall of the first receiving cavity 100, the first elastic portion 120 and the annular rib 124 being disposed within the fixing groove 106.

[0086] In this embodiment, the second elastic member 12 includes a first elastic portion 120, a second elastic portion 122, and an annular rib 124. The first elastic portion 120 has a first through hole 1260, and the second elastic portion 122 is disposed within the first through hole 1260, thereby allowing the annular rib 124 to connect the first elastic portion 120 and the second elastic portion 122. The second through hole 1262 is disposed on the second elastic portion 122. The first elastic member 10 includes a fixing groove 106. The fixing groove 106 is disposed on the inner wall of the first receiving cavity 100, and the first elastic portion 120 and the annular rib 124 are disposed within the fixing groove 106. This arrangement, by providing the second elastic portion 122 and the annular rib 124 within the fixing groove 106 of the first receiving cavity 100, makes the second elastic member 12 more stable, especially when the foot pad assembly 1 is deformed under force, ensuring the stability of the combined use of the first elastic member 10 and the second elastic member 12.

[0087] The specific shape of the first elastic part 120 can be set according to actual needs.

[0088] In some embodiments, the annular rib 124 is optionally connected to the outer periphery of the second elastic portion 122 and is disposed near one end of the second elastic portion 122.

[0089] In this embodiment, the annular rib 124 is connected to the outer periphery of the second elastic portion 122 and is disposed near one end of the second elastic portion 122, that is, the first elastic portion 120 is disposed near one end of the second elastic portion 122.

[0090] In some embodiments, the second elastic member 12 may extend out of or not extend out of the first receiving cavity 100.

[0091] In this embodiment, the second elastic member 12 may or may not extend out of the first receiving cavity 100. That is, the length of the second elastic member 12 can be set according to the actual situation to ensure the strength of the second elastic member 12.

[0092] In some embodiments, optionally, the second elastic member 12 extends out of the first receiving cavity 100, and the support portion 102 is disposed on the portion of the second elastic member 12 that extends out of the first receiving cavity 100.

[0093] In this embodiment, the second elastic element 12 extends out of the first receiving cavity 100. This allows the support portion 102 to be positioned on the portion of the second elastic element 12 extending out of the first receiving cavity 100. Consequently, the vibration generated by the compressor is first transmitted to the second elastic element 12, which then drives the first elastic element 10 to vibrate. This results in minute friction between the second elastic element 12 and the first elastic element 10 during vibration, thereby reducing vibration energy.

[0094] According to an embodiment of the first aspect of the present invention, a foot pad assembly 1 is provided, and the application of the foot pad assembly 1 in a refrigerator is described as an example. The refrigerator includes a compressor 2 and a base plate, the base plate having threaded holes for fixing screws 142. The foot pad assembly 1 includes: a rubber pad (first elastic element 10), silicone rubber (second elastic element 12), a bushing (fixing sleeve 140), and fixing screws 142. The internal cavity of the rubber pad contains solidified silicone rubber, allowing for minimal friction between the silicone rubber and the inner wall of the rubber pad cavity. The bushing is disposed in the through hole of the rubber pad and is limited by the constriction holes between the rubber pads. The fixing screws 142 are used to lock the metal bushing onto the refrigerator base plate 3. The compressor 2, the vibration source, presses down on the four foot pad assemblies 1 and is positioned on the base plate by the fixing screws 142.

[0095] The foot pad assembly 1 is a rubber pad composed of two materials. In this embodiment, the outer material is butyl rubber and the inner cavity material is silicone. The hardness of silicone is less than that of butyl rubber. In this embodiment, the silicone inside the cavity can also be replaced with other materials that are softer than the outer material.

[0096] The inner cavity of the rubber pad is a closed area enclosed by the inner surface of the rubber pad and the outer surface of the metal bushing. By injecting liquid silicone rubber into the cavity, the silicone rubber inside the cavity solidifies and fills the entire closed area, forming a support structure inside the original rubber pad.

[0097] The support structure is formed by the solidification of liquid silicone, and its shape fits perfectly with the inner cavity of the rubber pad. However, since there is no adhesion between the two, when the outer rubber pad deforms due to vibration, the deformation of the inner silicone rubber lags behind that of the outer rubber, thus causing a small displacement at the joint surface, dissipating the energy of vibration and achieving the technical effect of vibration reduction and noise reduction.

[0098] The supporting structure is formed by the solidification of liquid silicone, and its hardness is less than that of the external butyl rubber, such as... Figure 7 As shown, when the butyl rubber pad is not filled with silicone support, its supporting stiffness is mainly achieved by the thin walls on its sides. Based on experience and the fact that the refrigeration system is prone to crushing and deformation during long-distance transportation and long-term operation, the hollow structure may be at risk of being crushed. When it is filled with silicone support, its axial supporting stiffness is significantly improved, so its ability to resist fatigue deformation failure is stronger than that of the original hollow rubber pad.

[0099] The key points of this application are described in detail below:

[0100] This application addresses the deformation and crushing problems of excessively soft rubber feet during long-term refrigerator operation. It proposes a rubber foot assembly 1 suitable for refrigerator compressor 2. This assembly 1 has a simple structure, is installed using the same method as ordinary rubber feet, and offers superior vibration damping, noise reduction, and deformation resistance compared to ordinary rubber feet. The rubber foot assembly 1, based on the structure of an ordinary rubber foot, undergoes a glue-injection process. The cavity formed between the inner wall of the rubber foot (first elastic element 10) and the metal bushing (fixed sleeve 140) is filled with a softer silicone material. The silicone material is liquid in the foot foot cavity before solidification, and becomes soft silicone rubber after solidification, maintaining the original softness of the rubber foot. Furthermore, because the internal cavity of the rubber foot is filled with silicone rubber, the overall resistance to deformation is improved, making the rubber foot less prone to crushing after glue injection. Additionally, there are tiny gaps between the inner wall of the rubber foot cavity and the silicone rubber within the cavity. The vibration energy generated during compressor 2 operation can be dissipated through the small relative motion between them, a function that ordinary single-material rubber feet cannot achieve.

[0101] A second aspect of the invention provides a compressor 2 comprising: a foot pad assembly 1 as described in any embodiment of the first aspect.

[0102] The compressor 2 provided by the present invention includes the foot pad assembly 1 in any embodiment of the first aspect. Since the compressor 2 includes the foot pad assembly 1 in any embodiment of the first aspect, the compressor 2 provided by the present application also has all the beneficial technical effects of the foot pad assembly 1 in any embodiment of the first aspect, which will not be repeated here.

[0103] In some embodiments, the compressor 2 may optionally include a reciprocating compressor.

[0104] In some embodiments, the reciprocating compressor may optionally include a high-speed reciprocating compressor.

[0105] The vibration reduction and noise reduction principle of compressor 2 will be explained in detail below:

[0106] Compressor 2, as the core component of the refrigerator system, is typically mounted to the base plate of the refrigerator system via a rubber pad at its bottom. Specifically, the feet of compressor 2 are welded to its casing, and the feet rest on the rubber pad; the two are only in contact, not locked together. The rubber pad usually has a through hole in the center, with a small stepped constriction hole inside. This constriction hole is used to secure the bushing of compressor 2. The upper end of the bushing contacts a screw, which fixes the bushing to the base plate of the refrigerator system. The locked bushing provides positioning for the rubber pad, thus ensuring that compressor 2 maintains the correct position within the compressor compartment of the refrigerator system. Because compressor 2 generates vibration during operation, this vibration is transmitted to the base plate of the refrigerator system through the rubber pad, causing vibration and low-frequency noise in the refrigerator system. Over time, the system structure may also experience fatigue damage due to this vibration.

[0107] Due to the mounting structure between the compressor 2 rubber pad and bushing, the metal parts do not directly contact each other. The vibration of compressor 2 is attenuated by the rubber material before being transmitted to the metal base plate. The width of the constriction hole within the rubber pad determines the contact area between the rubber and metal materials. In the current design, if the axial stiffness of the rubber pad is low, its ability to suppress low-frequency noise in the refrigerator system is strong. However, since the weight of compressor 2 is entirely supported by the rubber pad, an excessively soft rubber pad may deform or even collapse during long-term refrigerator operation, thus reducing the vibration reduction and noise reduction effect.

[0108] A third aspect of the invention provides a refrigeration device comprising: a foot pad assembly 1 as described in any embodiment of the first aspect; and / or a compressor 2 as described in the embodiment of the second aspect.

[0109] The refrigeration device provided by the present invention includes a foot pad assembly 1 as described in any embodiment of the first aspect; and / or a compressor 2 as described in the embodiment of the second aspect. Since the refrigeration device includes the foot pad assembly 1 as described in any embodiment of the first aspect and / or the compressor 2 as described in the embodiment of the second aspect, the refrigeration device provided by this application also possesses all the beneficial technical effects of the foot pad assembly 1 as described in any embodiment of the first aspect and / or the compressor 2 as described in the embodiment of the second aspect, which will not be elaborated further here.
