Detailed Implementation

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] In related technologies, the compressor, as a core component of refrigeration equipment, generates vibrations during operation, thus affecting the user experience. The foot pads are crucial components connecting the compressor and the refrigeration equipment, and their vibration damping effect directly impacts the vibration and noise levels of the refrigeration equipment. When the refrigeration equipment is operating, the compressor's vibration excitation is transmitted to the equipment's base plate through the foot pads. The foot pads are prone to localized stress concentration, failing to meet the vibration damping requirements for both high-frequency and low-frequency vibrations, resulting in relatively high operating noise from the refrigeration equipment.

[0039] Based on this, refer to Figure 1 , Figure 2 , Figure 1 This is a partial schematic diagram of the compressor assembly according to an embodiment of the present invention. Figure 2 This is a cross-sectional view of the mounting plate 110, the foot pad assembly 200, and the connecting assembly according to an embodiment of the present invention. For example... Figure 1 , Figure 2 As shown, the first aspect of this utility model provides a compressor assembly, which includes a compressor, a foot pad assembly 200, and a connecting assembly. The compressor includes a housing 120 and a mounting plate 110 mounted on the outside of the housing 120. The mounting plate 110 is fixedly connected to the housing 120 and has a first mounting hole 111. The foot pad assembly 200 includes a lower foot pad 210 and an upper foot pad 220. The lower foot pad 210 is located below the mounting plate 110, and its upper end face abuts against the lower end face of the mounting plate 110. The upper foot pad 220 is located below the mounting plate 110, and its lower end face abuts against the upper end face of the mounting plate 110. The lower foot pad 210 has a plurality of spaced-apart first friction portions 212 on the side facing the upper foot pad 220. The upper foot pad 220 is provided with a plurality of spaced second friction parts 222 on the side facing the lower foot pad 210, extending axially along the first mounting hole 111. The number of first friction parts 212 and second friction parts 222 is equal. The first friction parts 212 and second friction parts 222 abut against each other. On the one hand, and on the other hand, under the vibration of the compressor, the first friction parts 212 move relative to the second friction parts 222 along the axial direction of the first mounting hole 111. The first friction parts 212 and the second friction parts 222 rub against each other. The first friction parts 212 and the second friction parts 222 dissipate the vibration energy of the compressor through friction, thereby reducing the vibration of the base plate of the refrigeration equipment and reducing the operating noise of the refrigeration equipment.

[0040] For example, when the refrigeration equipment is working, the vibration generated by the compressor is transmitted to the lower foot pad 210 and the upper foot pad 220 through the mounting plate 110. By setting multiple first friction parts 212 and multiple second friction parts 222, the vibration stress between the lower foot pad 210 and the upper foot pad 220 can be distributed to the first friction parts 212 and the second friction parts 222, which can prevent stress concentration in the foot pad assembly 200. Moreover, under the vibration of the compressor, the first friction parts 212 and the second friction parts 222 move relative to each other, so that the first friction parts 212 and the second friction parts 222 can rub against each other along the axial direction of the first mounting hole 111. The first friction parts 212 and the second friction parts 222 dissipate the vibration energy of the compressor through friction, thereby reducing the vibration of the base plate of the refrigeration equipment and reducing the operating noise of the refrigeration equipment.

[0041] It should be noted that the axis of the first friction part 212 is collinear with the axis of the corresponding second friction part 222, the axis of the first friction part 212 is parallel to the axis of the connecting assembly, or the axis of the first friction part 212 is inclined to the axis of the connecting assembly, which is not limited here.

[0042] It should be noted that one first friction part 212 and one second friction part 222 can be configured, which will not be elaborated here.

[0043] It should be noted that, for example, Figure 1 As shown, at least three first mounting holes 111 are provided, and these at least three first mounting holes 111 are spaced apart circumferentially along the compressor housing 120. At least three foot pad assemblies 200 and connecting assemblies are also provided correspondingly. The number of foot pad assemblies 200, connecting assemblies, and first mounting holes 111 are equal, which can reduce the operating noise of the refrigeration equipment. In another embodiment, at least three mounting plates 110 can also be provided, and these at least three mounting plates 110 are spaced apart circumferentially along the compressor housing 120. Each mounting plate 110 has one first mounting hole 111, and at least three foot pad assemblies 200 and connecting assemblies are also provided correspondingly. The number of foot pad assemblies 200, connecting assemblies, and mounting plates 110 are equal, which can also reduce the operating noise of the refrigeration equipment.

[0044] It should be noted that the lower foot pad 210 and the upper foot pad 220 are separate structures, which makes it easy to assemble the lower foot pad 210 and the upper foot pad 220 on the mounting plate 110, thereby improving the production efficiency of the refrigeration equipment.

[0045] It should be noted that by providing multiple first friction parts 212, the surface area of ​​the lower foot pad 210 can be increased, enhancing its heat dissipation performance. This helps prevent material aging under high-temperature environments, thereby extending the service life of the lower foot pad 210. Similarly, by providing multiple second friction parts 222, the surface area of ​​the upper foot pad 220 can be increased, enhancing its heat dissipation performance. This also helps prevent material aging under high-temperature environments, thereby extending the service life of the lower foot pad 210.

[0046] It should be noted that the compressor can be a rotary compressor, a reciprocating compressor, or a scroll compressor, etc., and there are no restrictions here.

[0047] Reference Figures 2 to 5 , Figure 3 This is a schematic diagram of the structure of the upper foot pad 220 according to an embodiment of the present invention. Figure 4 for Figure 3 Front view, Figure 5 This is a schematic diagram of the structure of the lower foot pad 210 according to an embodiment of the present invention. As shown in the figure, in this embodiment, all the first friction parts 212 are grooves, which are located on the upper end surface of the lower foot pad 210. All the second friction parts 222 are bosses, which are columnar structures. The upper end of the boss is connected to the side of the upper foot pad 220 facing the lower foot pad 210, and the lower end of the boss is accommodated in the corresponding groove. The outer peripheral surface of the boss abuts against the inner peripheral surface of the groove. Under the vibration of the compressor, the outer peripheral surface of the boss and the inner peripheral surface of the groove rub against each other, which can dissipate the vibration energy of the compressor, thereby reducing the operating noise of the refrigeration equipment.

[0048] In another embodiment, all the first friction parts 212 can be bosses, with the lower end of the boss connected to the upper end face of the lower foot pad 210, and all the second friction parts 222 can be grooves, with the grooves located on the side of the upper foot pad 220 facing the lower foot pad 210. The upper end of the boss is accommodated in the corresponding groove and abuts against the side wall of the groove. The first friction parts 212 and the second friction parts 222 can also dissipate the vibration energy of the compressor, which is not limited here.

[0049] In another embodiment, some of the first friction parts 212 may be grooves, while the remaining first friction parts 212 may be bosses. Some of the second friction parts 222 may be grooves, while the remaining second friction parts 222 may be bosses. The bosses on the lower foot pad 210 may be inserted into the grooves on the upper foot pad 220, and the bosses on the upper foot pad 220 may be inserted into the grooves on the lower foot pad 210. This is not a limitation.

[0050] It is understandable that by designing the first friction part 212 and the second friction part 222 as a structure in which a boss and a groove cooperate, the relative positions of the lower foot pad 210 and the upper foot pad 220 can be positioned, thereby improving the installation accuracy of the lower foot pad 210 and the upper foot pad 220 and ensuring close contact between the lower foot pad 210, the upper foot pad 220 and the mounting plate 110.

[0051] In another embodiment, the first friction part 212 is a first energy-dissipating protrusion with a first friction surface, and the second friction part 222 is a second energy-dissipating protrusion with a second friction surface. Along the radial direction of the first mounting hole 111, the first energy-dissipating protrusion and the second energy-dissipating protrusion overlap, and the first friction surface and the second friction surface abut against each other. Under the vibration of the compressor, the first friction surface can move relative to the second friction surface along the axial direction of the first mounting hole 111. The first energy-dissipating protrusion and the second energy-dissipating protrusion can also dissipate the vibration energy of the compressor, which is not limited here.

[0052] It should be noted that by designing the first friction part 212 and the second friction part 222 as a structure in which a boss and a groove cooperate, the height of the boss and the depth of the groove dynamically change during compressor operation, which can effectively dissipate vibration energy. This allows the foot pad assembly 200 to meet the vibration reduction requirements of the compressor under both high-frequency and low-frequency operating conditions, thereby improving the overall vibration reduction performance of the foot pad assembly 200. For example, taking the first friction part 212 as a groove and the second friction part 222 as a boss, the lower end of the boss abuts against the side wall of the groove. When the compressor is under high-frequency operating conditions, the vibration amplitude of the compressor is large. Because the lower end of the boss abuts against the side wall of the groove, the boss and the side wall of the groove can pull against each other, resulting in a large variation in the height of the boss and the depth of the groove, which can meet the vibration reduction requirements of the compressor under high-frequency operating conditions. When the compressor is under low-frequency operating conditions, the vibration amplitude of the compressor is small, and the variation in the height of the boss and the depth of the groove is small, which can meet the vibration reduction requirements of the compressor under low-frequency operating conditions.

[0053] Furthermore, by designing the first friction part 212 and the second friction part 222 as a structure in which the boss and the groove cooperate, the overall rigidity of the foot pad assembly 200 can be improved, thereby enhancing the structural stability of the foot pad assembly 200. When the compressor is working, it can prevent the first friction part 212 and the second friction part 222 from undergoing excessive deformation or displacement, thereby improving the service life of the foot pad assembly 200.

[0054] For example Figure 2As shown, in this embodiment, all second friction parts 222 are bosses. The upper foot pad 220 has a stepped portion 223 on the side facing the lower foot pad 210. One end of each second friction part 222 away from the first friction part 212 is connected to the lower surface of the stepped portion 223. Both the connecting component and the stepped portion 223 pass through the first mounting hole 111. This simplifies the structure of the mounting plate 110, eliminating the need for additional through holes for the second friction parts 222 to pass through on the mounting plate 110. This reduces the manufacturing cost of the mounting plate 110 and improves its production efficiency. Furthermore, by providing the stepped portion 223, the relative position of the mounting plate 110 and the upper foot pad 220 can be positioned, facilitating the assembly of the upper foot pad 220 and improving the assembly accuracy between the upper foot pad 220 and the mounting plate 110.

[0055] In another embodiment, the step portion 223 is provided on the side of the lower foot pad 210 facing the upper foot pad 220. All the first friction portions 212 are bosses. The end of each first friction portion 212 away from the second friction portion 222 is connected to the upper surface of the step portion 223. The connecting component and the step portion 223 are both inserted into the first mounting hole 111. This simplifies the structure of the mounting plate 110, eliminates the need to open additional through holes on the mounting plate 110 for the first friction portions 212 to pass through, reduces the manufacturing cost of the mounting plate 110, and improves the production efficiency of the mounting plate 110.

[0056] In this embodiment, the material of the foot pad assembly 200 is rubber, such as EPDM rubber or nitrile rubber. All first friction parts 212 are bosses, and the first friction parts 212 and the lower foot pad 210 are integrally structured, which can reduce the number of molds, thereby reducing the production and manufacturing costs of the molds, and thus reducing the production and manufacturing costs of the lower foot pad 210 and the first friction parts 212.

[0057] For example, the first friction part 212 and the lower foot pad 210 can be integrally molded by injection molding, which can reduce the number of molds and reduce the production cost of the molds, thereby reducing the production cost of the lower foot pad 210 and the first friction part 212.

[0058] In another embodiment, the first friction part 212 can also be connected and fixed to the lower foot pad 210 by heat fusion welding, or the first friction part 212 can be connected and fixed to the lower foot pad 210 by interference fit, snap-fit ​​or threaded connection, etc., without limitation.

[0059] As another implementation, all the second friction parts 222 can be bosses, and the second friction parts 222 and the upper foot pad 220 can be an integral structure. For example, the second friction parts 222 and the upper foot pad 220 can be integrally molded by injection molding, which can reduce the number of molds and reduce the production cost of the molds, thereby reducing the production cost of the second friction parts 222 and the upper foot pad 220. Similarly, the second friction parts 222 can also be connected and fixed to the upper foot pad 220 by heat fusion welding, or the second friction parts 222 can be connected and fixed to the upper foot pad 220 by interference fit, snap-fit, or threaded connection, etc., without limitation.

[0060] For example Figure 3 , Figure 5 As shown, in this embodiment, six second friction parts 222 are configured, and the six second friction parts 222 are equally spaced around the axis of the first mounting hole 111. Six first friction parts 212 are configured accordingly, which can disperse the vibration stress between the upper foot pad 220 and the lower foot pad 210 in all directions, so as to avoid local stress concentration in the foot pad assembly 200, thereby improving the service life of the foot pad assembly 200.

[0061] In another implementation, when N second friction parts 222 are arranged, the N second friction parts 222 are arranged in a regular N-sided array with intervals, and each second friction part 222 is located at the corresponding intersection of the regular N-sided array. The six second friction parts 222 are arranged in a regular N-sided array with intervals. For example, the six second friction parts 222 can also be arranged in a regular hexagon array with intervals, such as each second friction part 222 being located at the corresponding intersection of the regular hexagon. The six first friction parts 212 are arranged in a regular hexagon array with intervals, which can also disperse the vibration stress between the upper foot pad 220 and the lower foot pad 210 in all directions. N is a positive integer.

[0062] In another embodiment, the plurality of second friction parts 222 may be arranged in a linear array at intervals, and the plurality of first friction parts 212 may be arranged in a corresponding linear array at intervals, which will not be described in detail here.

[0063] Of course, in other specific embodiments, the number of second friction parts 222 may be two, three, four or five, etc., and there is no limitation here.

[0064] For example Figure 3 As shown, in this embodiment, the outer contour of the cross-section of the boss along the direction perpendicular to the axis of the first mounting hole 111 is a circular structure, that is, the boss is a cylindrical structure, which can avoid stress concentration at the connection position between the boss and the side wall of the groove, thereby improving the service life of the foot pad assembly 200.

[0065] For example, along the axis perpendicular to the first mounting hole 111, the cross-section of the boss has no sharp edges. When the vibration stress between the upper foot pad 220 and the lower foot pad 210 is distributed to the boss, the boss is less likely to generate stress concentration, thereby delaying the generation of fatigue cracks. The boss has stronger fatigue resistance and can improve the service life of the foot pad assembly 200.

[0066] As another implementation, the outer contour of the cross-section of the boss along the direction perpendicular to the axis of the first mounting hole 111 can also be an elliptical structure or a polygonal structure, without limitation.

[0067] It is understandable that, along the direction perpendicular to the axis of the first mounting hole 111, the cross-section of the groove matches the outer contour of the cross-section of the boss, so that the inner circumferential surface of the groove fits against the outer circumferential surface of the boss. The vibration stress on the boss can be evenly distributed through the corresponding groove, thereby avoiding stress concentration on the boss.

[0068] Reference Figure 5 , Figure 6 , Figure 6 for Figure 5 The figure shows a front view. As shown in the figure, in this embodiment, the lower foot pad 210 includes four annular portions 213. The four annular portions 213 are connected sequentially along the axial direction of the second mounting hole 211. A vibration damping groove 214 is formed between adjacent annular portions 213, which can reduce the axial stiffness of the lower foot pad 210. When the lower foot pad 210 is subjected to axial force, the lower foot pad 210 is more likely to collapse and deform, which can better attenuate the vibration transmitted by the compressor to the bottom plate of the refrigeration equipment through the lower foot pad 210, and avoid resonance noise between the compressor and the bottom plate of the refrigeration equipment.

[0069] For example, a vibration damping groove 214 is formed between the outer peripheral surface of the upper annular portion 213 and the outer peripheral surface of the lower annular portion 213. The vibration damping groove 214 is annular and extends around the axis of the second mounting hole 211. This reduces the axial stiffness of the lower foot pad 210. When the lower foot pad 210 is subjected to axial force, it is easier for the lower foot pad 210 to collapse and deform, which can better attenuate the vibration transmitted by the compressor to the base plate of the refrigeration equipment through the lower foot pad 210.

[0070] Of course, in other specific embodiments, the number of annular portions 213 may also be two, three or five, etc., and there is no limitation here.

[0071] For example Figure 6 As shown in this embodiment, the width of the damping groove 214 gradually decreases along the concave direction of the damping groove 214. On the one hand, this can ensure the tangential stiffness of the lower foot pad 210, and on the other hand, it can reduce the axial stiffness of the lower foot pad 210, which can effectively reduce the operating noise of the refrigeration equipment during operation.

[0072] It should be noted that the width of the damping groove 214 refers to the minimum distance between the outer peripheral surface of the upper annular portion 213 and the outer peripheral surface of the lower annular portion 213 along the axial direction of the lower foot pad 210.

[0073] For example Figure 1 , Figure 2 As shown, in this embodiment, the connecting assembly includes a bolt 310 and a nut 320. The bolt 310 includes a shank 312 and a head 311. One end of the shank 312 is connected to the head 311. The shank 312 passes through the second mounting hole 211, the first mounting hole 111, and the third mounting hole 221 from bottom to top. The head 311 abuts against the side of the lower foot pad 210 away from the upper foot pad 220. The nut 320 is sleeved on the outer periphery of the end of the shank 312 away from the head 311, and the nut 320 is threadedly connected to the shank 312. The nut 320 abuts against the side of the upper foot pad 220 away from the lower foot pad 210, so that a stable connection is achieved between the lower foot pad 210, the mounting plate 110, and the upper foot pad 220. The operation is simple, convenient, and quick, which can improve the production efficiency of the refrigeration equipment.

[0074] It should be noted that the connecting assembly may also include a spring washer, which is sleeved on the rod portion 312 and located between the mounting plate 110 and the lower foot pad 210, or the spring washer is located between the mounting plate 110 and the upper foot pad 220.

[0075] In another embodiment, the connecting assembly includes a pin and a retaining ring. The lower end of the pin, the lower foot pad 210, abuts against the side opposite to the upper foot pad 220. The upper end of the pin passes through the second mounting hole 211, the first mounting hole 111, and the third mounting hole 221 from bottom to top, and the upper end of the pin protrudes from the third mounting hole 221. The retaining ring engages with the upper end of the pin, which also enables a stable connection between the lower foot pad 210, the mounting plate 110, and the upper foot pad 220. No limitation is imposed here.

[0076] A second aspect of this utility model provides a refrigeration device, which includes the compressor assembly described in the above embodiments. The refrigeration device can be a central air conditioning system, a packaged air conditioner, a split air conditioner, a ducted air conditioner, a window air conditioner, or other similar equipment.

[0077] When the compressor assembly of the first aspect of this utility model is used, the vibration generated by the compressor is transmitted to the lower foot pad 210 and the upper foot pad 220 through the mounting plate 110 during operation of the refrigeration equipment. By providing a plurality of first friction parts 212 and a plurality of second friction parts 222, the vibration stress between the lower foot pad 210 and the upper foot pad 220 can be distributed to the first friction parts 212 and the second friction parts 222, which can prevent stress concentration in the foot pad assembly 200. Moreover, under the vibration of the compressor, the first friction parts 212 and the second friction parts 222 move relative to each other, so that the first friction parts 212 and the second friction parts 222 can rub against each other. The first friction parts 212 and the second friction parts 222 dissipate the vibration energy of the compressor through friction, thereby reducing the vibration of the base plate of the refrigeration equipment and reducing the operating noise of the refrigeration equipment.

[0078] Since the refrigeration equipment adopts all the technical solutions of the compressor in the above embodiments, it has at least all the beneficial effects brought about by the technical solutions in the above embodiments, which will not be repeated here.

[0079] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiment. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
