Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a vibration damping pad, compressor assembly and refrigeration equipment. Background Art

[0002] In recent years, with the improvement of living standards, the popularity of refrigeration equipment has been increasing year by year. Consumers have higher and higher requirements for its use, demanding not only strong freezing capacity but also excellent stability and safety. As a core component of refrigeration equipment, the reciprocating compressor generates vibration during operation, which in turn affects the user experience. 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.

[0003] When existing refrigeration equipment is working, the vibration excitation of the compressor is transmitted to the base plate of the refrigeration equipment through the foot pads, causing the base plate of the refrigeration equipment to resonate, and the noise generated when the refrigeration equipment is running is still relatively large. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a vibration-damping foot pad that can reduce the noise during the operation of refrigeration equipment.

[0005] This utility model also proposes a compressor assembly having the above-mentioned vibration-damping foot pads.

[0006] This utility model also proposes a refrigeration device having the above-mentioned compressor assembly.

[0007] According to the first embodiment of the present invention, a vibration-damping foot pad is applied to a stand having a compressor, the vibration-damping foot pad comprising:

[0008] The foot pad body has at least two vibration damping cavities spaced apart along the axial direction of the foot pad body. A first mounting hole for a connector to pass through is provided between two adjacent vibration damping cavities. The foot pad body has a first end face and a second end face that are opposite to each other along the axial direction. The first end face abuts against the lower end face of the foot frame. The first end face has a first opening that connects to the uppermost vibration damping cavity and allows the connector to pass through upward. The second end face has a second opening that connects to the lowermost vibration damping cavity and allows the connector to pass through downward. The maximum outer diameter of the first end face is D1, the maximum outer diameter of the second end face is D2, and the maximum outer diameter of the outer circumferential surface of the foot pad body is D3, satisfying that D1 is less than D3 and D2 is less than D3.

[0009] According to an embodiment of the present invention, the vibration-damping foot pad has at least the following beneficial effects:

[0010] When assembling the vibration damping pads, the first end face of the pad body abuts against the lower end face of the frame, and the second end face of the pad body connects to the base plate of the refrigeration equipment. The connecting parts are sequentially inserted from top to bottom through the first opening, the upper vibration damping cavity, the first mounting hole, the lower vibration damping cavity, and the second opening. Since the maximum outer diameter of the first end face is smaller than the maximum outer diameter of the outer circumference of the pad body, and the maximum outer diameter of the second end face is smaller than the maximum outer diameter of the outer circumference of the pad body, the area of ​​the first and second end faces can be reduced, thereby increasing the pressure on the pad body and making the pad body more prone to deformation. Moreover, by increasing the number of vibration damping cavities, the axial stiffness of the pad body can be reduced, and the axial vibration damping effect of the pad body can be improved, thereby reducing the noise generated during the operation of the refrigeration equipment.

[0011] According to some embodiments of the present invention, the outer peripheral surface of the foot pad body is provided with a vibration damping groove, the vibration damping groove is arranged around the axis of the first mounting hole, and along the axial direction of the foot pad body, the vibration damping groove is located between two adjacent vibration damping cavities.

[0012] According to some embodiments of the present invention, the foot pad body includes at least two sequentially connected annular portions, the number of annular portions being the same as the number of vibration damping cavities, the vibration damping cavities being disposed within the corresponding annular portions, and the vibration damping grooves being formed between adjacent annular portions.

[0013] According to some embodiments of the present invention, along the axial direction of the foot pad body, the outer diameter of the annular portion first increases and then decreases.

[0014] According to some embodiments of the present invention, in the cross-section passing through the axis of the foot pad body, the outer contour of the cross-section of the annular portion is a waist-shaped structure, and / or, the cross-section of the vibration damping cavity is a waist-shaped structure.

[0015] According to some embodiments of the present invention, the width of the vibration damping groove gradually decreases along the concave direction of the vibration damping groove.

[0016] According to some embodiments of the present invention, the sidewall of the first mounting hole is provided with a rib, and the rib is arranged around the axis of the first mounting hole.

[0017] According to some embodiments of the present invention, the vibration damping pad further includes a snap-fit ​​component, which is disposed on the first end face and has a second mounting hole communicating with the first opening.

[0018] According to some embodiments of the present invention, the diameter of the first opening is larger than the diameter of the second opening, and the diameter of the second mounting hole is greater than or equal to the diameter of the first opening.

[0035] In related technologies, reciprocating compressors, as core components of refrigeration equipment, generate vibrations during operation, thus affecting the user experience. 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. Currently, when existing refrigeration equipment is operating, the compressor's vibration excitation is transmitted to the equipment's base plate through the foot pads, causing the base plate to resonate, resulting in relatively high noise levels during operation.

[0036] Reference Figure 1 , Figure 2 , Figure 1 This diagram illustrates an assembly of a vibration-damping foot pad, a foot bracket, and a connector according to a novel embodiment of the present invention. Figure 2 A schematic diagram of the internal structure of a vibration-damping foot pad according to another embodiment of the present invention is shown. For example... Figure 1 , Figure 2As shown, in this embodiment, the vibration-damping foot pad includes a foot pad body 100. The foot pad body 100 has two vibration-damping cavities 110 inside. The two vibration-damping cavities 110 are arranged side-by-side and spaced apart along the axial direction of the foot pad body 100. A first mounting hole 120 is provided in the portion of the foot pad body 100 located between the two vibration-damping cavities 110. The first mounting hole 120 extends vertically and is configured to connect the two vibration-damping cavities 110. The foot pad body 100 has a first end face 101 and a second end face 102. The first end face 101 and the second end face 102 are arranged opposite to each other along the axial direction of the foot pad body 100. The first end face 101 is used to abut against the lower end face of the compressor's foot bracket 310. The first end face 101 has a first opening 103 connecting to the upper vibration-damping cavity 110. The first opening 103 is used for the connector to pass upwards. The second end face 102 is used to abut against the base plate 400 of the refrigeration equipment. The second end face 102 is provided with a second opening 104 that connects to the vibration damping cavity 110 located below. The second opening 104 is used for the connector to pass through downward. The maximum outer diameter of the first end face 101 is D1, the maximum outer diameter of the second end face 102 is D2, and the maximum outer diameter of the outer peripheral surface of the foot pad body 100 is D3, satisfying that: D1 < D3 and D2 < D3. In this way, the contact area of ​​the first end face 101 and the second end face 102 can be reduced, thereby increasing the pressure on the foot pad body 100. The foot pad body 100 is more likely to deform. Moreover, by increasing the number of vibration damping cavities 110, the axial stiffness of the foot pad body 100 can be reduced, and the axial vibration damping effect of the foot pad body 100 can be improved, thereby reducing the noise generated during the operation of the refrigeration equipment.

[0037] For example, when assembling the vibration damping pads, the first end face 101 of the pad body 100 abuts against the lower end face of the foot bracket 310 of the compressor 300, and the second end face 102 of the pad body 100 is connected to the base plate 400 of the refrigeration equipment. The connecting parts are sequentially inserted from top to bottom through the first opening 103, the upper vibration damping cavity 110, the first mounting hole 120, the lower vibration damping cavity 110, and the second opening 104. Since the maximum outer diameter of the first end face 101 is smaller than the outer perimeter of the pad body 100... The maximum outer diameter of the first end face 101 and the maximum outer diameter of the second end face 102 are smaller than the maximum outer diameter of the outer peripheral surface of the foot pad body 100. This reduces the area of ​​the first end face 101 and the second end face 102, thereby increasing the pressure on the foot pad body 100. The foot pad body 100 is more prone to deformation. Moreover, by increasing the number of damping cavities 110, the axial stiffness of the foot pad body 100 can be reduced, and the axial damping effect of the foot pad body 100 can be improved, thereby reducing the noise generated during the operation of the refrigeration equipment.

[0038] As another implementation, the vibration damping cavity 110 can also be configured with three or four, etc. Taking the configuration of three vibration damping cavities 110 as an example, there are two corresponding configurations of the first mounting hole 120. One of the first mounting holes 120 connects the uppermost vibration damping cavity 110 and the middle vibration damping cavity 110, and the other first mounting hole 120 connects the lowermost vibration damping cavity 110 and the middle vibration damping cavity 110. This can also reduce the axial stiffness of the foot pad body 100, which is not limited here.

[0039] It should be noted that the maximum outer diameter of the first end face 101 is smaller than the maximum diameter of the uppermost damping cavity 110. The part of the foot pad body 100 located below the first end face 101 is hollowed out, which can better attenuate the vibration transmitted by the compressor 300 to the base plate 400 of the refrigeration equipment through the foot pad body 100. Similarly, since the maximum outer diameter of the second end face 102 is smaller than the maximum diameter of the lowermost damping cavity 110, the part of the foot pad body 100 located above the second end face 102 is hollowed out, which can better attenuate the vibration transmitted by the compressor 300 to the base plate 400 of the refrigeration equipment through the foot pad body 100, and avoid resonance noise between the compressor 300 and the base plate 400 of the refrigeration equipment. This will not be elaborated further here.

[0040] It should be noted that the connecting parts are bolts or screws, which enable the stand 310 to achieve a stable connection with the base plate 400 of the refrigeration equipment, which will not be elaborated further here.

[0041] It should be noted that the shape of the outer contour of the first end face or the second end face can be circular, elliptical or polygonal. The maximum outer diameter of the first end face 101 refers to the longest distance between any two points on the outer contour of the first end face 101, and the maximum outer diameter of the second end face 102 refers to the longest distance between any two points on the outer contour of the second end face 102. This will not be elaborated further here.

[0042] For example Figure 1 As shown, in this embodiment, the outer peripheral surface of the foot pad body 100 is provided with a vibration damping groove 130. The vibration damping groove 130 is an annular structure and is arranged around the axis of the first mounting hole 120. Along the axial direction of the foot pad body 100, the vibration damping groove 130 is located between two adjacent vibration damping cavities 110, which can reduce the axial stiffness of the foot pad body 100. When the foot pad body 100 is subjected to axial force, the vibration damping cavity 110 is more likely to collapse and deform, which can better attenuate the vibration transmitted by the compressor 300 to the base plate 400 of the refrigeration equipment through the foot pad body 100, and avoid the compressor 300 and the base plate 400 of the refrigeration equipment from generating resonance noise.

[0043] It should be noted that on the cross-section perpendicular to the axis of the foot pad body 100, the projection of the damping groove 130 coincides with the projection of each damping cavity 110. That is, the minimum diameter of the damping groove 130 is smaller than the maximum diameter of the damping cavity 110, which can reduce the axial stiffness of the foot pad body 100 and is conducive to the collapse deformation of the damping cavity 110. This will not be elaborated further here.

[0044] It should be noted that at least one vibration damping groove 130 is configured. For example, when there are three vibration damping cavities 110, there are two vibration damping grooves 130 respectively. One vibration damping groove 130 is located between the uppermost vibration damping cavity 110 and the middle vibration damping cavity 110, and the other vibration damping groove 130 is located between the lowermost vibration damping cavity 110 and the middle vibration damping cavity 110. No limitation is made here.

[0045] In this embodiment, the foot pad body 100 includes two annular portions 140 connected sequentially in the vertical direction. The annular portions 140 correspond one-to-one with the vibration damping cavities 110. Each annular portion 140 is provided with a vibration damping cavity 110. The outer peripheral surface of the upper annular portion 140 and the outer peripheral surface of the lower annular portion 140 together define a vibration damping groove 130, which can ensure the tangential stiffness of the foot pad body 100. When the foot pad body 100 is subjected to tangential force, it can reduce the left and right swing amplitude of the compressor 300 relative to the axis of the foot pad body 100, and reduce the lateral vibration of the compressor 300.

[0046] It should be noted that the annular structure of the cross-section of the annular portion 140 on the cross-section perpendicular to the axis of the foot pad body 100 can ensure that the tangential stiffness of the foot pad body 100 is equal at all positions in the circumferential direction, thereby improving the tangential stiffness of the foot pad body 100, which will not be elaborated here.

[0047] It should be noted that the annular portion 140 can also be configured with three or four, etc. The number of annular portions 140 is equal to that of the vibration damping cavity 110, which will not be elaborated here.

[0048] For example Figure 1 As shown, in this embodiment, the width of the damping groove 130 gradually decreases along the concave direction of the damping groove 130. On the one hand, this can ensure the tangential stiffness of the foot pad body 100, and on the other hand, it can reduce the axial stiffness of the foot pad body 100, thereby effectively reducing the operating noise of the refrigeration equipment during operation.

[0049] It should be noted that the width of the damping groove 130 refers to the minimum distance between the outer peripheral surface of the upper annular portion 140 and the outer peripheral surface of the lower annular portion 140 along the axial direction of the foot pad body 100.

[0050] In this embodiment, the outer diameter of the uppermost annular portion 140 narrows in the direction toward the first end face 101, so that the maximum outer diameter of the first end face 101 is smaller than the maximum outer diameter of the uppermost annular portion 140, which can reduce the contact area between the first end face 101 and the foot bracket 310, thereby improving the axial vibration reduction effect of the foot pad body 100.

[0051] In this embodiment, the outer diameter of the lowermost annular portion 140 narrows in the direction toward the second end face 102, so that the maximum outer diameter of the second end face 102 is smaller than the maximum outer diameter of the lowermost annular portion 140. This reduces the contact area between the second end face 102 and the base plate 400 of the refrigeration equipment, thereby improving the axial vibration reduction effect of the foot pad body 100.

[0052] For example Figure 1 , Figure 2 As shown, in this embodiment, along the axial direction of the foot pad body 100, the outer diameter of the annular portion 140 first increases and then decreases. That is, along the axial direction of the foot pad body 100, the width of the annular portion 140 at the middle position gradually narrows towards both ends, so that the maximum outer diameter of the first end face 101 is smaller than the maximum outer diameter of the uppermost annular portion 140, and the maximum outer diameter of the second end face 102 is smaller than the maximum outer diameter of the lowermost annular portion 140. This reduces the contact area between the first end face 101 and the foot bracket 310, and reduces the contact area between the second end face 102 and the base plate 400 of the refrigeration equipment, so as to better buffer the axial force on the foot pad body 100 and improve the axial vibration reduction effect of the foot pad body 100.

[0053] For example, in the cross-section through the axis of the foot pad body 100, the outer contour of the outer peripheral surface of the annular portion 140 is a waist-shaped structure, and the two ends of the waist-shaped structure are semi-circular. This can reduce the contact area between the first end face 101 and the foot bracket 310, and also reduce the contact area between the second end face 102 and the base plate 400 of the refrigeration equipment, thereby reducing the axial stiffness of the foot pad body 100.

[0054] As another embodiment, the outer peripheral surface of the annular portion 140 may also include two conical surfaces, which are mirror-symmetrically arranged along the cross-section perpendicular to the axis of the foot pad body 100, without limitation.

[0055] In this embodiment, in order to improve the tangential stiffness of the foot pad body 100, the cross-section of the damping cavity 110 on the cross-section through the axis of the foot pad body 100 is a waist-shaped structure with semicircles at both ends. When the foot pad body 100 is subjected to tangential force, the sidewall of the damping cavity 110 can offset part of the tangential force, thereby reducing the left and right swing amplitude of the compressor 300 relative to the axis of the foot pad body 100.

[0056] It should be noted that, on the cross-section of the foot pad body 100 along its axis, the outer contour of the outer periphery of the annular portion 140 is the same as the cross-sectional shape of the damping cavity 110, that is, the wall thickness of the annular portion 140 is uniform, which can ensure that the foot pad body 100 has sufficient tangential stiffness.

[0057] For example Figure 1 As shown, in this embodiment, the side wall of the first mounting hole 120 is provided with a rib 150. The rib 150 is a ring structure and is arranged around the axis of the first mounting hole 120. The rib 150 can improve the structural strength of the first mounting hole 120. When the foot pad body 100 is subjected to tangential force, the rib 150 can reduce the deformation of the first mounting hole 120 to ensure the tangential stiffness of the foot pad body 100.

[0058] It should be noted that when assembling the compressor 300, the bushing is inserted through the first mounting hole 120, and the outer circumferential surface of the bushing abuts against the rib 150. Then, the connector is inserted through the first mounting hole 120, which can fix the position of the bushing inside the foot pad body 100, so as to avoid the bushing colliding with the connector and causing the working noise of the refrigeration equipment to deteriorate during operation.

[0059] Reference Figure 3 , Figure 3 This is a schematic diagram of the structure of a vibration-damping foot pad according to another embodiment of the present invention. In this embodiment, the foot pad body 100 further includes a snap-fit ​​member 200, which is disposed on the first end face 101. The foot bracket 310 has a through hole, and the snap-fit ​​member 200 passes through the through hole and abuts against the upper edge of the through hole, so that the snap-fit ​​member 200 can be snapped with the foot bracket 310. This can pre-fix the relative position of the foot pad body 100 and the compressor 300, so that the foot pad body 100 can move with the compressor 300 to the next assembly process, which can facilitate the production and manufacturing of refrigeration equipment.

[0060] To facilitate the assembly of the compressor 300, a second mounting hole 210 is provided on the snap-fit ​​part 200, which connects to the first opening 103. The second mounting hole 210, the first opening 103, the first mounting hole 120, and the second opening 104 are all coaxially arranged. From top to bottom, the connector passes through the second mounting hole 210, the first opening 103, the first mounting hole 120, and the second opening 104 in sequence, which can facilitate the connection of the connector to the fixed bracket 310 and the base plate 400 of the refrigeration equipment.

[0061] It should be noted that the snap-fit ​​part 200 and the annular part 140 are an integral structure. The vibration damping pad is made of soft rubber or other soft materials. The snap-fit ​​part 200 and the annular part 140 are integrally molded by injection molding, which can reduce the number of molds and reduce the production and manufacturing costs of the molds, thereby reducing the production and manufacturing costs of the vibration damping pad.

[0062] For example Figure 1 , Figure 2 As shown, in this embodiment, the diameter of the first opening is D4, the diameter of the second opening is D5, and the diameter of the second mounting hole is D6, satisfying: D4 > D5, D6 = D4. That is, the diameter of the first opening 103 is greater than the diameter of the second opening 104, and the diameter of the second mounting hole 210 is equal to the diameter of the first opening 103. When installing the connector, the connector does not contact the side wall of the second mounting hole 210, which can avoid hard contact between the connector and the foot pad body 100, thereby avoiding the deterioration of vibration and noise.

[0063] It should be noted that "hard contact" refers to the situation where, under various loads such as pipeline tension, its own rotational torque, and stud deformation compressive force, the rotation axis of the compressor 300 may shift to a certain extent, leading to contact between the vibration damping pads and the connecting parts. When the contact force reaches a certain level, i.e., "hard contact," the vibration damping pads fail to dampen vibrations, and the vibration and noise deteriorate accordingly.

[0064] As another implementation, the diameter of the second mounting hole 210 can also be larger than the diameter of the first opening 103, which will not be elaborated here.

[0065] The compressor assembly of the second embodiment of this utility model includes a compressor 300 and the vibration-damping foot pads of the first embodiment described above. The compressor 300 has a foot bracket 310, and the first end face 101 of the foot pad body 1001 abuts against the lower end face of the foot bracket 310 to better buffer the axial force on the foot pad body 100, thereby improving the axial vibration damping effect of the foot pad body 100 and reducing the noise generated during the operation of the refrigeration equipment. The compressor can be a reciprocating compressor, a rotary compressor, or a scroll compressor, etc.

[0066] For example, when assembling the vibration-damping foot pad according to the first embodiment of this invention, the first end face 101 of the foot pad body 100 abuts against the lower end face of the foot bracket 310 of the compressor 300, and the second end face 102 of the foot pad body 100 is connected to the base plate 400 of the refrigeration equipment. The connecting piece passes through the first opening 103, the upper vibration-damping cavity 110, the first mounting hole 120, the lower vibration-damping cavity 110, and the second opening 104 in sequence from top to bottom. Since the maximum outer diameter of the first end face 101 is smaller than that of the foot pad, the vibration-damping foot pad is used in this case. The maximum outer diameter of the outer circumferential surface of the pad body 100 and the maximum outer diameter of the second end face 102 are smaller than the maximum outer diameter of the outer circumferential surface of the pad body 100. This reduces the area of ​​the first end face 101 and the second end face 102, thereby increasing the pressure on the pad body 100. The pad body 100 is more prone to deformation. Moreover, by increasing the number of damping cavities 110, the axial stiffness of the pad body 100 can be reduced, and the axial damping effect of the pad body 100 can be improved, thereby reducing the noise generated during the operation of the refrigeration equipment.

[0067] Reference Figure 4 , Figure 4 This is a partial structural schematic diagram of the refrigeration equipment according to an embodiment of the present invention. For example... Figure 4 As shown, the refrigeration equipment of the third embodiment of this utility model includes a base plate 400 and a compressor assembly as described in the second embodiment above, with the second end face 102 abutting against the base plate 400. The refrigeration equipment can be a refrigerator, freezer, etc.

[0068] Since the refrigeration equipment adopts all the technical solutions of the compressor assembly of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0069] 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.
