Description

TECHNICAL FIELD

[0001] The present application relates to the field of compressor parts, in particular to a foot pad, a compressor assembly and a refrigeration device. BACKGROUND

[0002] The foot pad is an important part connecting the compressor foot, and the damping effect of the foot pad directly affects the vibration noise level of the compressor and the electrical product using the compressor.

[0003] In the related art, the foot pad is of solid structure and has large rigidity, and the vibration excitation of the compressor foot pad will be transmitted to the bottom plate of the electrical product through the foot pad, thereby causing the bottom plate of the electrical product to resonate and generate a fundamental frequency resonance noise. SUMMARY

[0004] The present application aims to at least solve one of the technical problems existing in the prior art.

[0005] To this end, the first aspect of the present application provides a foot pad.

[0006] The second aspect of the present application provides a compressor assembly.

[0007] The third aspect of the present application provides a refrigeration device.

[0008] The first aspect of the present application provides a foot pad, comprising: a mounting structure; a bearing structure arranged on the mounting structure, the bearing structure comprising a bearing surface; and a recess arranged on the outer periphery of the bearing structure and recessed from the bearing surface.

[0009] The foot pad provided by the present application comprises a mounting structure, a bearing structure and a recess. The mounting structure is used to fix the foot pad on the compressor; the bearing structure is arranged on the outer periphery of the mounting structure, and the bearing structure comprises a bearing surface. Specifically, the bearing surface is arranged on the mounting structure, and the bearing surface is in contact with the foot of the compressor. The bearing structure bears the weight of the compressor and absorbs the vibration generated during the operation of the device. Further, the recess recessed downward is arranged on the bearing surface. The recess can reduce the contact area between the device and the foot pad and reduce the transmission of vibration between the device and the foot pad, thereby reducing the resonance between different devices, reducing the noise generated by the vibration of the device, and effectively reducing the overall noise of the device. In addition, the design of the recess facilitates the at least partially hollow design of the foot pad, which can effectively reduce the strength and rigidity of the foot pad itself to weaken the limitation that the hardness of the solid foot pad in the related art cannot be reduced.

[0010] Specifically, in the process of mounting the foot pad and the compressor, the recess is arranged on the bearing surface, which can reduce the contact area between the compressor and the bearing surface, and can weaken the limitation that the hardness of the solid foot pad in the prior art cannot be reduced. Therefore, the volume of the bearing structure is reduced by the design of the recess, the area of the bearing surface is reduced, the stiffness of the foot pad is reduced, the foot pad is more easily deformed under stress, the vibration transmitted by the foot pad is reduced, the vibration transmission between the compressor and the bottom plate of the refrigeration equipment is reduced, and the compressor and the refrigeration equipment are prevented from producing humming noise due to vibration. The noise of the overall equipment can be effectively reduced.

[0011] Specifically, the foot pad provided by the present application can include an elastic foot pad (for example, a rubber foot pad), which has the characteristics of being easily deformed under stress and can absorb the vibration generated by the compressor, thereby reducing the vibration transmission between the compressor and the bottom plate of the refrigeration equipment and preventing the compressor and the refrigeration equipment from producing humming noise due to vibration. In addition, the elastic foot pad also has wear resistance, which can ensure that the service life of the foot pad is long.

[0012] In some possible designs, the recess includes a ring-shaped groove, and the ring-shaped groove is distributed on the circumferential side of the mounting structure.

[0013] In this design, the recess includes a ring-shaped groove. By arranging the ring-shaped groove around the mounting structure, the contact area between the foot pad and the bottom foot of the compressor can be reduced, thereby reducing the vibration transmitted by the foot pad and effectively reducing the vibration transmission between the compressor and the bottom plate of the refrigeration equipment. In addition, the ring-shaped groove is arranged on the circumferential side of the mounting structure, which can ensure that the contact area between the foot pad of the compressor and the bearing surface is more uniform, thereby improving the stable support of the foot pad on the compressor and preventing the compressor from shaking during use.

[0014] In this design, the outer edge contour line of the mounting structure is located in the ring-shaped groove in the height direction of the foot pad. In this way, during use of the foot pad, the mounting structure and the bearing structure will not interfere with each other. Specifically, during use of the foot pad, the mounting structure ensures the connection between the entire foot pad and the bottom foot of the compressor, and the bearing surface of the bearing structure directly contacts the bottom foot of the compressor. The structure of the mounting structure is optimized in the present application, so that the bottom foot of the compressor can directly contact the bearing surface of the bearing structure. In addition, the recess recessed in the bearing surface is arranged on the bearing structure, thereby weakening the bearing structure and improving the deformation ability of the bearing structure, so that the foot pad is more easily deformed, thereby effectively absorbing the vibration transmitted by the compressor, reducing the resonance between the compressor and the bottom plate of the refrigeration equipment, and further reducing the noise generated by the refrigeration equipment during operation.

[0015] In some possible design, the foot pad further comprises a through hole arranged on the bearing structure, the through hole is located at the bottom of the recess and communicates with the recess.

[0016] In this design, the foot pad further comprises a through hole. The through hole is arranged at the bottom of the recess and communicates with the recess. In this way, the present application can further reduce the rigidity of the foot pad, especially the rigidity of the bearing structure, reduce the resonance between the compressor and the bottom plate of the refrigeration equipment, and further reduce the noise generated during the operation of the refrigeration equipment.

[0017] Specifically, the through hole is arranged at the bottom of the recess and communicates with the recess. In this way, by the cooperation of the recess and the through hole, the internal structure of the foot pad is hollowed out, thereby weakening the overall structural strength of the foot pad, reducing the rigidity of the foot pad, making the foot pad more easily deformed under force, reducing the vibration transmitted by the foot pad, reducing the resonance between the compressor and the bottom plate of the refrigeration equipment, and further reducing the noise generated during the operation of the refrigeration equipment.

[0018] In some possible design, the number of through holes is multiple, and the multiple through holes are distributed on the circumferential side of the mounting structure.

[0019] In this design, the number of through holes is multiple. In this design, the present application arranges multiple through holes around the mounting structure on the foot pad, so that the overall structure of the foot pad has more hollow spaces, further reducing the overall structure of the foot pad, and making the foot pad more easily deformed under force without vibration.

[0020] In addition, the multiple through holes are distributed on the circumferential side of the mounting structure, and the multiple through holes are uniformly distributed on the circumferential side of the mounting structure, so that the multiple through holes uniformly weaken the rigidity of the foot pad along the circumferential side of the mounting structure, ensuring that the deformation amount of the foot pad is consistent everywhere, thereby ensuring that the foot pad stably and uniformly supports the compressor.

[0021] In some possible design, the diameter of the through hole is greater than or equal to 2mm and less than or equal to 3mm.

[0022] In this design, the diameter of the through hole is limited. In this design, the diameter of the through hole is limited to be greater than or equal to 2mm and less than or equal to 3mm. In this way, the rigidity of the foot pad is ensured to be reduced, and the foot pad has a certain rigidity on the basis of deformation under force, thereby preventing the foot pad from being damaged due to excessive force.

[0023] In some possible design, the number of through holes is greater than or equal to 3 and less than or equal to 8.

[0024] In the design, the number of through holes is set. Among them, the number of through holes is greater than or equal to 3 and less than or equal to 8. Specifically, the number of through holes determines the weakening strength and uniformity of the stiffness of the foot pad. Among them, when the diameters of the through holes are equal, the more the number of through holes, the weaker the stiffness of the foot pad; in the case of a certain stiffness of the foot pad, the more the number of through holes, the more uniform the stiffness distribution of the foot pad. Therefore, the number of through holes is set to be greater than or equal to 3 and less than or equal to 8, which ensures that the stiffness of the foot pad is reduced, and the foot pad has a certain stiffness, ensures that the deformation of the foot pad is consistent, and further ensures that the foot pad stably supports and uniformly supports the compressor.

[0025] In some possible designs, the foot pad further comprises a column body arranged on the bearing structure and located in the recess.

[0026] In the design, the foot pad further comprises a column body. Among them, the column body is arranged in the recess and protrudes from the bottom wall of the recess. By arranging the column body in the recess, the shape of the foot pad can be optimized, so that the foot pad does not resonate with the compressor during use, thereby reducing the resonance between the compressor and the bottom plate of the refrigeration equipment, and further reducing the noise generated during operation of the refrigeration equipment.

[0027] In some possible designs, the number of column bodies is multiple, and the multiple column bodies are distributed on the periphery of the mounting structure.

[0028] In the design, the number of column bodies is multiple. Among them, the multiple column bodies are arranged around the periphery of the mounting structure, thereby changing the weight distribution of the foot. In this way, during use, the foot pad can further avoid resonance with the compressor, thereby reducing the resonance between the compressor and the bottom plate of the refrigeration equipment, and further reducing the noise generated during operation of the refrigeration equipment. Specifically, the number and distribution position of the column bodies can be designed according to actual conditions, as long as the foot pad can avoid resonance with the compressor, it can be realized.

[0029] In some possible designs, the diameter of the column body is greater than or equal to 2mm and less than or equal to 3mm.

[0030] In the design, the diameter of the column body is set to be greater than or equal to 2mm and less than or equal to 3mm. Among them, the diameter of the column body is designed according to different compressors to adapt to the working conditions of different compressors, which can effectively adapt to different compressors to reduce the vibration transmitted by the foot pad, thereby reducing the noise generated by the resonance of the foot pad and the compressor.

[0031] In some possible designs, the number of column bodies is greater than or equal to 3 and less than or equal to 8.

[0032] In addition, the number of column bodies is greater than or equal to 3 and less than or equal to 8. Different numbers of column bodies can be designed for different compressors to adapt to the working conditions of different compressors, which can effectively adapt to different compressors to reduce the vibration transmitted by the foot pad and reduce the noise generated by the resonance of the foot pad and the compressor.

[0033] In some possible designs, the bearing structure is provided with both through holes and column bodies, and the through holes and the column bodies are alternately distributed along the circumference of the mounting structure. In this way, the through holes can reduce the rigidity of the foot pad, so that the foot pad is more likely to deform under force, and the column bodies can allow the column bodies to absorb vibration. Therefore, the through holes and the column bodies can work together to minimize the vibration transmitted by the foot pad, reduce the vibration transmitted by the foot pad, and reduce the noise generated by the resonance of the foot pad and the compressor.

[0034] In some possible designs, the bearing structure includes a support wall located on the circumferential side of the mounting structure, a recess located between the support wall and the mounting structure, and a bearing surface located on the end face of the support wall.

[0035] In this design, the bearing structure includes a support wall. The support wall is arranged on the circumferential side of the mounting structure and surrounds the mounting structure, so that the support wall is annular as a whole. The recess is arranged between the support wall and the mounting structure. In addition, the bearing surface described above is arranged on the support wall, and the bottom feet of the compressor are supported by the bearing surface.

[0036] In some possible designs, the wall thickness of the support wall is greater than or equal to 3 mm in a direction from the middle of the foot pad to the circumferential edge of the foot pad.

[0037] In this design, the wall thickness of the support wall is greater than or equal to 3 mm in a direction from the middle of the foot pad to the circumferential edge of the foot pad. In this way, the strength of the support wall is ensured, and the support effect of the support wall on the compressor is ensured. Specifically, the wall thickness of the support wall can be designed for different compressors, so that the support wall can stably support compressors of different weights, thereby increasing the universality of the foot pad.

[0038] In addition, the bearing structure is provided with a recess, and the recess is arranged between the support wall and the mounting structure, so as to further reduce the wall thickness of the support wall and further reduce the rigidity of the support structure and the entire foot pad.

[0039] In some possible designs, in the height direction of the foot pad, the ratio of the recess size of the recess to the height of the bearing structure is less than or equal to 1 / 3.

[0040] In the design, in the height direction of the foot pad, the ratio of the recessed size of the recess to the height of the bearing structure is less than or equal to 1 / 3. In this way, on the basis of ensuring that the recess can reduce the rigidity of the bearing structure and the entire foot pad, the bearing structure and the foot pad are ensured to have sufficient strength, thereby ensuring that the foot pad stably supports the compressor.

[0041] In some possible designs, in the height direction of the foot pad, the height of the bearing structure is greater than or equal to 10 mm and less than or equal to 20 mm.

[0042] In the design, in the height direction of the foot pad, the height of the bearing structure is greater than or equal to 10 mm and less than or equal to 20 mm. In this way, the height of the bearing structure is greater than or equal to 10 mm, so that the bearing structure has a certain height to support the compressor. In addition, the height of the bearing structure is less than or equal to 20 mm, on the basis of ensuring that the compressor is stably supported, the material of the bearing structure is reduced, and the structure and size of the bearing structure are simplified, the size of the bearing structure and the entire foot pad is reduced, and the miniaturization design of the bearing structure and the foot pad can be realized.

[0043] In some possible designs, in the height direction of the foot pad, the height of the foot pad is greater than or equal to 18 mm and less than or equal to 25 mm.

[0044] In the design, in the height direction of the foot pad, the height of the foot pad is greater than or equal to 18 mm and less than or equal to 25 mm. In this way, the height of the foot pad is greater than or equal to 18 mm, so that the foot pad has a certain height to support the compressor. In addition, the height of the foot pad is less than or equal to 25 mm, on the basis of ensuring that the compressor is stably supported, the material of the foot pad is reduced, and the structure and size of the foot pad are simplified, the size of the foot pad is reduced, and the miniaturization design of the foot pad can be realized.

[0045] In some possible designs, the foot pad further includes: a mounting hole arranged on the mounting structure; and a stepped hole arranged on the bearing structure and located at the bottom of the mounting hole, the stepped hole being in communication with the mounting hole and having a diameter greater than that of the mounting hole.

[0046] In the design, the foot pad further includes the mounting hole and the stepped hole. The mounting hole is arranged on the mounting structure, and the stepped hole is arranged on the bearing structure and located at the bottom of the mounting hole. In this way, the foot pad can be fixedly connected to the foot pad of the compressor through the mounting hole, and the installation of the foot pad is ensured. In addition, the stepped hole is in communication with the mounting hole and has a diameter greater than that of the mounting hole. The mounting hole and the stepped hole penetrate through the entire foot pad, and the rigidity of the foot pad is further reduced on the basis of ensuring the overall installation of the foot pad through the cooperation of the mounting hole and the stepped hole.

[0047] In some possible design, the diameter of the mounting hole is greater than or equal to 9 mm and less than or equal to 13 mm.

[0048] In this design, the diameter of the mounting hole is greater than or equal to 9 mm and less than or equal to 13 mm. In this way, by setting the diameter of the mounting hole, it is ensured that the mounting hole uses connecting components of different specifications, so as to improve the applicability of the foot pad. Specifically, the diameter of the mounting hole can be designed according to actual conditions, which will not be discussed here.

[0049] In some possible design, the diameter of the stepped hole is greater than or equal to 14 mm and less than or equal to 17 mm.

[0050] In this design, the diameter of the stepped hole is greater than or equal to 14 mm and less than or equal to 17 mm. In this way, by setting the diameter of the stepped hole, it is ensured that the stepped hole uses connecting components of different specifications, so as to improve the applicability of the foot pad. Specifically, the diameter of the stepped hole can be designed according to actual conditions, which will not be discussed here. In addition, the diameter of the stepped hole can also be designed according to actual rigidity requirements, so as to ensure that the rigidity of the foot pad is reduced.

[0052] The compressor assembly provided by the present application comprises the foot pad according to the first aspect of the present application. Therefore, the foot pad has all the beneficial effects described above, which will not be discussed in detail here. Further, the compressor assembly further comprises a compressor, and the foot is connected to the foot pad.

[0053] During the operation of the compressor, the body will vibrate. The foot pad is connected to the foot, and the structure of the foot pad is improved, so that the rigidity of the foot pad is reduced. The foot pad absorbs the vibration generated by the body, and the foot pad will not resonate with the body of the compressor, so as to reduce the noise generated during the operation of the compressor.

[0068] In order to enable the above-mentioned objects, features and advantages of the present application to be more clearly understood and to be implemented, the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.​​​​

[0069] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the present application can be practiced without the specific details set forth in this description.

[0070] Some embodiments of the present application will be described below with reference to Figures 1 to 7 to provide a foot pad 10, a compressor assembly and a refrigeration device.

[0071] As shown in Figure 1 and Figure 4 , a first embodiment of the present application provides a foot pad 10, which comprises a mounting structure 100, a bearing structure 108 and a recess 102.

[0072] The mounting structure 100 is used to fix the foot pad 10 on the compressor; the bearing structure 108 is arranged on the outer periphery of the mounting structure 100, and the bearing structure 108 comprises a bearing surface 110. The bearing surface 110 is arranged on the mounting structure 100, and the bearing surface 110 is in contact with the bottom foot 202 of the compressor. The bearing structure 108 bears the weight of the compressor and absorbs the vibration generated during the operation of the device.

[0073] Further, the embodiment is provided with the downwardly recessed recess 102 on the bearing surface 110. The contact area between the device and the foot pad 10 can be reduced through the recess 102, the vibration transmitted between the device and the foot pad 10 can be reduced, the resonance between different devices can be reduced, the noise generated by the vibration of the device can be reduced, and the overall noise of the device can be effectively reduced. In addition, the design of the recess 102 facilitates the realization of the at least partially hollow design of the foot pad 10, which can effectively reduce the strength and stiffness of the foot pad 10 itself to weaken the limitation that the hardness of the solid foot pad in the related art cannot be reduced.

[0074] Specifically, as shown in Figure 7 , the recess 102 arranged on the bearing surface 110 during the installation of the foot pad 10 and the compressor can reduce the contact area between the compressor and the bearing surface 110, and can weaken the limitation that the hardness of the solid foot pad in the related art cannot be reduced.

[0075] Therefore, as shown in Figure 1 and Figure 4 , the design of the recess 102 reduces the volume of the bearing structure 108 and the area of the bearing surface 110, reduces the stiffness of the foot pad 10, makes the foot pad 10 more easily deformed under force, thereby reducing the vibration transmitted by the foot pad 10, further reducing the vibration transmitted between the compressor and the bottom plate of the refrigeration device, avoiding the generation of the humming noise of the compressor and the refrigeration device due to the vibration, and effectively reducing the overall noise of the device.

[0076] Specifically, the foot pad 10 proposed in the embodiment can include an elastic foot pad (for example, a rubber foot pad), which has the characteristics of being easily deformed under force and can absorb the vibration generated by the compressor, thereby reducing the vibration transmission between the compressor and the bottom plate of the refrigeration equipment and avoiding the generation of a humming noise due to the vibration of the compressor and the refrigeration equipment. In addition, the elastic foot pad also has wear resistance, which can ensure that the service life of the foot pad 10 is long.

[0077] The second embodiment of the present application proposes a foot pad 10, which is further based on the first embodiment and has the following characteristics:

[0078] As shown in Figure 1 and Figure 4 , the recess 102 includes an annular groove. Among them, by setting the annular groove around the mounting structure 100, the contact area between the foot pad 10 and the bottom foot 202 of the compressor can be reduced, thereby reducing the vibration transmitted by the foot pad 10 and effectively reducing the vibration transmission between the compressor and the bottom plate of the refrigeration equipment.

[0079] In addition, as shown in Figure 1 and Figure 4 , the annular groove is arranged on the circumferential side of the mounting structure 100, which can ensure that the contact area between the foot pad 10 of the compressor and the bearing surface 110 is more uniform, thereby improving the stable support of the foot pad 10 on the compressor and avoiding the shaking of the compressor during use.

[0080] In this embodiment, further as shown in Figure 2 and Figure 5 , the outer edge contour line of the mounting structure 100 is located in the annular groove in the height direction of the foot pad 10. In this way, during the use of the foot pad 10, the mounting structure 100 and the bearing structure 108 will not interfere with each other.

[0081] Specifically, as shown in Figure 7 , during the use of the foot pad 10, the mounting structure 100 ensures the connection between the entire foot pad 10 and the bottom foot 202 of the compressor, and the bearing surface 110 of the bearing structure 108 directly contacts the bottom foot 202 of the compressor. The present application optimizes the structure of the mounting structure 100 to ensure that the bottom foot 202 of the compressor can directly contact the bearing surface 110 of the bearing structure 108.

[0082] Moreover, the embodiment is provided with the recess 102 recessed in the bearing surface 110 on the bearing structure 108, which further weakens the bearing structure 108 and improves the deformation ability of the bearing structure 108, so that the foot pad 10 is more easily deformed, thereby effectively absorbing the vibration transmitted by the compressor, reducing the resonance between the compressor and the bottom plate of the refrigeration equipment, and further reducing the noise generated during the operation of the refrigeration equipment.

[0083] In addition, the foot pad 10 of the embodiment has all the beneficial effects of the foot pad 10 of the first embodiment, and can effectively reduce the strength and rigidity of the foot pad 10 itself to weaken the limitation that the hardness of the solid foot pad in the related art cannot be reduced, which will not be discussed in detail here.

[0084] The third embodiment of the present application proposes a foot pad 10, which is further based on the first embodiment and the second embodiment, and has:

[0085] As shown in Figure 1 , Figure 2 and Figure 3 , the foot pad 10 further comprises a through hole 106. The through hole 106 is arranged at the bottom of the recess 102, and the through hole 106 is in communication with the recess 102. In this way, the present application can further reduce the rigidity of the foot pad 10, especially the rigidity of the bearing structure 108, by arranging the through hole 106 on the bearing structure 108, so as to reduce the resonance between the compressor and the bottom plate of the refrigeration equipment, and further reduce the noise generated when the refrigeration equipment is running.

[0086] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , the through hole 106 of the embodiment is arranged at the bottom of the recess 102, and the through hole 106 is in communication with the recess 102. In this way, by cooperating the recess 102 with the through hole 106, the internal structure of the foot pad 10 is hollowed out, thereby weakening the overall structural strength of the foot pad 10, reducing the rigidity of the foot pad 10, making the foot pad 10 more easily deformed under stress, reducing the vibration transmitted by the foot pad 10, reducing the resonance between the compressor and the bottom plate of the refrigeration equipment, and further reducing the noise generated when the refrigeration equipment is running.

[0087] In this embodiment, further, as shown in Figure 1 , Figure 2 and Figure 3 , the number of through holes 106 is multiple. In this embodiment, multiple through holes 106 are arranged around the mounting structure 100 of the foot pad 10, so that the overall structure of the foot pad 10 has more hollow spaces, further reducing the overall structure of the foot pad 10, making the foot pad 10 more easily deformed under stress, and not vibrating under stress.

[0088] In addition, as shown in Figure 1 , Figure 2 and Figure 3As shown, the plurality of through holes 106 are distributed on the circumferential side of the mounting structure 100, and the plurality of through holes 106 are uniformly distributed on the circumferential side of the mounting structure 100, so that the plurality of through holes 106 uniformly weaken the rigidity of the foot pad 10 along the circumferential side of the mounting structure 100, ensuring that the foot pad 10 is more easily deformed under force, while ensuring that the deformation amount of the foot pad 10 is consistent everywhere, thereby ensuring that the foot pad 10 stably and uniformly supports the compressor.

[0089] In this embodiment, further, as shown in Figure 2 , the diameter D1 of the through hole 106 is limited. Among them, the diameter D1 of the through hole 106 is limited to be greater than or equal to 2mm and less than or equal to 3mm. In this way, while ensuring that the rigidity of the foot pad 10 is reduced, and on the basis of force deformation, the foot pad 10 is ensured to have a certain rigidity, so that the foot pad 10 will not be damaged due to excessive force.

[0090] Specifically, as shown in Figure 2 , the diameter D1 of the through hole 106 can be 2mm, 2.2mm, 2.4mm, 2.5mm, 2.6mm, 2.8mm, 3mm, etc. Herein, it is not specifically limited, as long as it can ensure stable installation of the foot pad 10, it can be realized.

[0091] In this embodiment, further, as shown in Figure 1 , Figure 2 and Figure 3 , the number of through holes 106 is set in this embodiment. Among them, the number of through holes 106 is greater than or equal to 3 and less than or equal to 8. Specifically, the number of through holes 106 determines the weakening strength and uniformity of the rigidity of the foot pad 10. Among them, in the case that the diameter D1 of the through hole 106 is equal, the more the number of through holes 106, the weaker the rigidity of the foot pad 10; in the case that the rigidity of the foot pad 10 is constant, the more the number of through holes 106, the more uniform the rigidity distribution of the foot pad 10.

[0092] Therefore, as shown in Figure 1 , Figure 2 and Figure 3 , the number of through holes 106 is set to be greater than or equal to 3 and less than or equal to 8 in this embodiment, which ensures that the rigidity of the foot pad 10 is reduced, and the foot pad has a certain rigidity, ensuring that the deformation amount of the foot pad 10 is consistent everywhere, thereby ensuring that the foot pad 10 stably and uniformly supports the compressor.

[0093] Specifically, the number of through holes 106 can be 3, 4, 5, 6, 7, 8, etc. Herein, it is not specifically limited. As long as it can ensure that the rigidity of the foot pad 10 is reduced, it can be realized.

[0094] In addition, the foot pad 10 provided in the embodiment has all the beneficial effects of the foot pad 10 of the first embodiment, and can effectively reduce the strength and rigidity of the foot pad 10 itself to weaken the limitation that the hardness of the solid foot pad cannot be reduced in the related art, which will not be discussed in detail here.

[0095] The fourth embodiment of the present application provides a foot pad 10, which is further based on the first embodiment and the second embodiment, and has:

[0096] As shown in Figure 4 , Figure 5 and Figure 6 , the foot pad 10 further comprises a column body 112. The column body 112 is arranged in the recess 102 and protrudes from the bottom wall of the recess 102. By arranging the column body 112 in the recess 102, the shape of the foot pad 10 can be optimized, so that the foot pad 10 does not resonate with the compressor during use, thereby reducing the resonance between the compressor and the bottom plate of the refrigeration equipment, and further reducing the noise generated by the refrigeration equipment during operation.

[0097] In this embodiment, further as shown in Figure 4 , Figure 5 and Figure 6 , the number of column bodies 112 is multiple. The multiple column bodies 112 are arranged around the circumferential side of the mounting structure 100, thereby changing the weight distribution of the foot 202. In this way, during use, the foot pad 10 can further avoid resonance with the compressor, thereby reducing the resonance between the compressor and the bottom plate of the refrigeration equipment, and further reducing the noise generated by the refrigeration equipment during operation.

[0098] Specifically, the number and distribution position of the column bodies 112 can be designed according to actual conditions, as long as the resonance between the foot pad 10 and the compressor can be avoided.

[0099] In this embodiment, further as shown in Figure 4 , Figure 5 and Figure 6 , the diameter D2 of the column body 112 is greater than or equal to 2 mm and less than or equal to 3 mm. The diameter D2 of the column body 112 is designed according to different compressors to adapt to the working conditions of different compressors, which can effectively adapt to different compressors to reduce the vibration transmitted by the foot pad 10, thereby reducing the noise generated by the resonance between the foot pad 10 and the compressor.

[0100] Specifically, the diameter D2 of the column body 112 can be 2 mm, 2.2 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.8 mm, 3 mm, etc. Herein, it is not specifically limited as long as the resonance between the foot pad 10 and the compressor can be avoided.

[0101] In this embodiment, the number of column bodies 112 is set to be greater than or equal to 3 and less than or equal to 8. Among them, different numbers of column bodies 112 can be designed for different compressors to adapt to the working conditions of different compressors, which can effectively adapt to different compressors to reduce the vibration transmitted by the foot pad 10 to reduce the noise generated by the resonance of the foot pad 10 and the compressor.

[0102] Specifically, the number of column bodies 112 can be 3, 4, 5, 6, 7, 8, etc., which is not specifically limited here. As long as the stiffness of the foot pad 10 can be reduced, it can be realized.

[0103] In addition, the foot pad 10 of the present embodiment has all the beneficial effects of the foot pad 10 of the first embodiment, which can effectively reduce the strength and stiffness of the foot pad 10 itself to weaken the limitation that the hardness of the solid foot pad in the related art cannot be reduced. It will not be discussed in detail here.

[0104] The fifth embodiment of the present application proposes a foot pad 10, which is further based on the first embodiment and the second embodiment:

[0105] The foot pad 10 also includes through holes 106 and column bodies 112 (not shown in the figure, but those skilled in the art can understand this embodiment based on the description of the third embodiment and the fourth embodiment described above). Among them, the bearing structure 108 is provided with through holes 106 and column bodies 112 at the same time, and the through holes 106 and the column bodies 112 are alternately distributed along the circumference of the mounting structure 100. In this way, the through holes 106 can reduce the stiffness of the foot pad 10, so that the foot pad 10 is more likely to deform under stress, and the column bodies 112 can allow the column bodies 112 to absorb vibration. Therefore, the present application can make the through holes 106 and the column bodies 112 work together to minimize the vibration transmitted by the foot pad 10, reduce the vibration transmitted by the foot pad 10, and reduce the noise generated by the resonance of the foot pad 10 and the compressor.

[0106] In this embodiment, the number of through holes 106 is multiple, and the multiple through holes 106 are distributed on the circumferential side of the mounting structure 100. The diameter D1 of the through hole 106 is greater than or equal to 2mm and less than or equal to 3mm. The number of through holes 106 is greater than or equal to 3 and less than or equal to 8. In this way, while ensuring that the foot pad 10 is more likely to deform under stress, it ensures that the deformation amount of the foot pad 10 is consistent everywhere, thereby ensuring that the foot pad 10 stably and uniformly supports the compressor.

[0107] In this embodiment, the number of the column bodies 112 is multiple, and the multiple column bodies 112 are distributed on the circumferential side of the mounting structure 100. The diameter D2 of the column body 112 is greater than or equal to 2 mm and less than or equal to 3 mm. The number of the column bodies 112 is greater than or equal to 3 and less than or equal to 8. In this way, the foot pad 10 can further avoid resonance with the compressor during use, thereby reducing resonance between the compressor and the bottom plate of the refrigeration equipment, and further reducing noise generated by the refrigeration equipment during operation.

[0108] On the basis of any one of the above embodiments, further, as shown in Figure 2 and Figure 5 , the mounting structure 100 comprises a support wall. The support wall 116 is arranged on the circumferential side of the mounting structure 100 and surrounds the mounting structure 100, so that the support wall 116 is annular as a whole. The recess 102 is arranged between the support wall and the mounting structure 100. In addition, the bearing surface 110 described above is arranged on the support wall, and the bottom foot 202 of the compressor is borne by the bearing surface 110.

[0109] Further, as shown in Figure 2 and Figure 5 , from the direction of the middle part of the foot pad 10 to the circumferential edge of the foot pad 10, the wall thickness d of the support wall is greater than or equal to 3 mm. In this way, the support wall has a certain strength, and the support effect of the support wall 116 on the compressor is ensured. Specifically, the wall thickness d of the support wall 116 can be designed according to different compressors, so that the support wall 116 can stably support compressors of different weights, thereby increasing the universality of the foot pad 10.

[0110] In particular, as shown in Figure 2 and Figure 5 , the present application is provided with the recess 102 on the bearing structure 108, and the recess 102 is arranged between the support wall 116 and the mounting structure 100, and the wall thickness d of the support wall 116 is reduced through the recess 102, so as to further reduce the rigidity of the support structure and the entire foot pad 10.

[0111] Specifically, as shown in Figure 2 and Figure 5 , from the direction of the middle part of the foot pad 10 to the circumferential edge of the foot pad 10, the thickness of the support wall can be 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4 mm, 4.5 mm, 5 mm, etc., which is not specifically limited here. As long as it can ensure stable support for the compressor, it can be realized.

[0112] In addition, the foot pad 10 provided in the embodiment has all the beneficial effects of the foot pad 10 of the first embodiment, and can effectively reduce the strength and rigidity of the foot pad 10 itself to weaken the limitation that the hardness of the solid foot pad in the related art cannot be reduced, which will not be discussed in detail here.

[0113] On the basis of any one of the above embodiments, further, as shown in Figure 2 and Figure 5 , in the height direction of the foot pad 10, the ratio of the recess size H1 of the recess 102 to the height H2 of the load-bearing structure 108 is less than or equal to 1 / 3. In this way, on the basis of ensuring that the recess 102 can reduce the rigidity of the load-bearing structure 108 and the entire foot pad 10, the load-bearing structure 108 and the foot pad 10 are ensured to have sufficient strength, and thus the stable support of the foot pad 10 to the compressor is ensured.

[0114] Specifically, as shown in Figure 2 and Figure 5 , in the height direction of the foot pad 10, the ratio of the recess size H1 of the recess 102 to the height H2 of the load-bearing structure 108 can be 1 / 6, 1 / 5, 1 / 4, 1 / 3, etc., which is not specifically limited here. As long as the rigidity of the load-bearing structure 108 and the entire foot pad 10 can be reduced on the basis of ensuring that the load-bearing structure 108 and the foot pad 10 have sufficient strength, it can be achieved.

[0115] In addition, the foot pad 10 provided in the embodiment has all the beneficial effects of the foot pad 10 of the first embodiment, and can effectively reduce the strength and rigidity of the foot pad 10 itself to weaken the limitation that the hardness of the solid foot pad in the related art cannot be reduced, which will not be discussed in detail here.

[0116] On the basis of any one of the above embodiments, further, as shown in Figure 2 and Figure 5 , in the height direction of the foot pad 10, the height H2 of the load-bearing structure 108 is greater than or equal to 10 mm and less than or equal to 20 mm. In this way, the height H2 of the load-bearing structure 108 is greater than or equal to 10 mm, so that the load-bearing structure 108 has a certain height to support the compressor. In addition, as shown in Figure 2 and Figure 5 , the height H2 of the load-bearing structure 108 is less than or equal to 20 mm, on the basis of ensuring stable support of the compressor, the material of the load-bearing structure 108 is reduced, and the structure and size of the load-bearing structure 108 are simplified, the size of the load-bearing structure 108 and the entire foot pad 10 is reduced, and the miniaturization design of the load-bearing structure 108 and the foot pad 10 can be achieved.

In this way, the height H3 of the foot pad 10 is greater than or equal to 18 mm, so that the foot pad 10 has a certain height to support the compressor. In addition, the height H3 of the foot pad 10 is less than or equal to 25 mm, which reduces the material of the foot pad 10 on the basis of ensuring stable support for the compressor, simplifies the structure and size of the foot pad 10, reduces the size of the foot pad 10, and can realize the miniaturization design of the foot pad 10.

[0119] Specifically, as shown in Figure 2 and Figure 5 As shown in the height direction of the foot pad 10, the height H3 of the foot pad 10 can be 18 mm, 20 mm, 22 mm, 24 mm, 25 mm, etc., which is not specifically limited here. As long as it can ensure stable support for the compressor, it can be realized.

[0120] On the basis of any of the above embodiments, further as shown in Figure 2 and Figure 5 The foot pad 10 further comprises a mounting hole 104 and a stepped hole 114. The mounting hole 104 is provided on the mounting structure 100, the stepped hole 114 is provided on the bearing structure 108, and the stepped hole 114 is located at the bottom of the mounting hole 104.

[0121] Further, as shown in Figure 2 and Figure 5 The stepped hole 114 is in communication with the mounting hole 104, and the diameter D4 of the stepped hole 114 is greater than the diameter D3 of the mounting hole 104. The mounting hole 104 and the stepped hole 114 in communication penetrate through the entire foot pad 10, and further through the cooperation of the mounting hole 104 and the stepped hole 114, the rigidity of the foot pad 10 is further reduced on the basis of ensuring the overall installation of the foot pad 10.
