Description

Technical Field

[0001] This application belongs to the field of vibration reduction technology, and in particular relates to a vibration-damping foot pad and a temperature control device. Background Technology

[0002] The compressor is the core component of the refrigerator's refrigeration system and also the main source of vibration in the system.

[0003] To attenuate the vibration energy generated by the compressor, existing vibration reduction methods for refrigerator compressors mainly rely on vibration damping pads to provide weak circumferential and axial constraints on the compressor, thereby attenuating the vibration energy generated by the compressor's vibration.

[0004] However, due to the limited compressibility of the lower half of the existing vibration damping pads in both the circumferential and axial directions, the attenuation of vibration energy in the circumferential and axial directions of the compressor is limited, resulting in significant vibration during actual operation. When the compressor generates high-frequency and severe vibrations during operation, it produces intense vibration excitation. Under the action of axial and tangential forces, the vibration damping pads are compressed to their limits (the damping pads are crushed), and the vibration energy is directly transmitted to the refrigerator body and the compressor's piping, leading to excessive noise and vibration, and in severe cases, even damaging the vibration damping pads. Summary of the Invention

[0005] The purpose of this application is to provide a vibration damping pad and a temperature control device, which aims to solve the problem that the vibration damping pads used in existing temperature control devices have poor vibration damping capabilities, resulting in excessive noise and vibration, or even damage to the vibration damping pads.

[0006] To achieve the above objectives, the technical solution adopted in this application embodiment is: a vibration-damping foot pad is provided, the vibration-damping foot pad comprising:

[0007] A support cylinder having a first end for connecting to a fixed mounting surface and a second end opposite to the first end;

[0008] The first damping ring wall has a first inner ring periphery and a first outer ring periphery surrounding the first inner ring periphery.

The wall surface of the first damping ring wall is inclined from the first outer ring periphery to the first inner ring periphery in a direction away from the first end. The first damping ring wall can produce elastic deformation, that is, the first damping ring wall has elasticity.

[0009] A connector is connected to the periphery of the first inner ring. The connector has an annular groove for mounting the foot of the vibrator.

[0014] In one embodiment, the vibration-damping pad further includes a second vibration-damping ring wall and a bottom support platform. The second vibration-damping ring wall has an inner edge and an outer edge surrounding the inner edge. The outer edge is connected to the first end, and the inner edge is connected to one end of the bottom support platform. The other end of the bottom support platform is used to support the fixed mounting surface. The inclination direction of the wall surface of the second vibration-damping ring wall is opposite to the inclination direction of the wall surface of the first vibration-damping ring wall. The second vibration-damping ring wall is capable of elastic deformation (i.e., the second vibration-damping ring wall is elastic). The bottom support platform has a perforation opposite to the through hole.

[0015] In one embodiment, the axial projected area of ​​the bottom support platform is smaller or larger than the axial projected area of ​​the second damping ring wall.

[0016] In one embodiment, the vibration damping pad further includes a bottom connecting cylinder, one end of which is connected to the inner edge, and the other end of which is connected to the bottom support platform, and the axial projection area of ​​the bottom connecting cylinder is smaller than the axial projection area of ​​the bottom support platform.

[0017] In one embodiment, the support cylinder is provided with a boss structure, which is used to enhance the support rigidity of the support cylinder.

[0018] In one embodiment, the boss structure is at least one annular boss disposed circumferentially on the inner and / or outer sidewalls of the support cylinder.

[0019] In one embodiment, the annular boss includes a first ring segment, a second ring segment, and a third ring segment. One end of the first ring segment is connected to the inner wall of the support cylinder, and the other end of the first ring segment is connected to the end of the second ring segment away from the connecting body. The third ring segment is connected to the end of the second ring segment facing the connecting body. The first ring segment and the third ring segment are located on opposite sides of the second ring segment.

[0020] In one embodiment, at least one annular adjustment groove is provided on the inner and / or outer sidewalls of the support cylinder in a circumferential manner.

[0021] In one embodiment, the diameter of the cross-sectional profile of the annular adjusting groove is d1, the diameter of the through hole corresponding to the support cylinder is D1, the diameter of the outer circle of the cross-section of the support cylinder is D2, and 0 < d1 < D2 - D1.

[0022] In one embodiment, the boss structure is a plurality of strip-shaped bosses disposed on the inner or outer sidewall of the support cylinder, each of the strip-shaped bosses extending in the axial direction.

[0023] In one embodiment, the plurality of strip-shaped protrusions are divided into multiple groups, and each strip-shaped protrusion in each group is evenly distributed around the perimeter.

[0028] The embodiments of this application have at least the following beneficial effects:

[0029] The vibration damping pads provided in this embodiment of the invention are used to install and fix the vibrator on the fixed mounting surface. During assembly, the bottom foot of the vibrator is fitted into the annular groove of the connecting body, and the limiting ring supports the bottom foot of the vibrator. Then, the fasteners are passed through the through hole and connected to the fixed mounting surface. After assembly, since the wall surface of the first vibration damping ring is inclined from the periphery of the first outer ring to the periphery of the first inner ring away from the first end, and the first vibration damping ring wall can generate elastic deformation in the axial direction, under the gravity of the vibrator, the first vibration damping ring wall undergoes elastic deformation in the axial direction and sinks, thereby allowing the vibrator to be balanced and fixedly connected to the fixed mounting surface. During the process of the vibrator generating vibration energy, the vibration energy is first transferred to the connecting body, and then to the first vibration damping ring wall. The first vibration damping ring wall further undergoes elastic deformation under the action of vibration energy, thereby converting the vibration energy into the deformation potential energy and thermal internal energy of the first vibration damping ring wall. In this way, the vibration energy transmitted to the fixed mounting surface is effectively reduced, and the noise generated by the vibration energy on the fixed mounting surface is reduced, thereby achieving the technical effect of noise reduction.

[0056] Definition: The axial direction is the vertical direction, which is also the axis direction of the vibration damping pad; the circumferential direction is the circumferential direction around the axis direction of the vibration damping pad.

[0057] Example 1:

[0058] Embodiment 1 of the present invention provides a vibration damping pad for mounting a vibrator 100 on a fixed mounting surface (when the vibrator 100 is directly mounted on the ground, the fixed mounting surface is the ground; when the vibrator 100 is mounted on a work platform, the fixed mounting surface is the table surface of the work platform; when the vibrator 100 is mounted inside the equipment housing, the fixed mounting surface is the inner side wall of the equipment housing; etc.). During the operation of the vibrator 100, the vibrator 100 generates vibration, which is then transmitted to the vibration pad. The vibration pad converts the mechanical energy generated by the vibration of the vibrator 100 to achieve the purpose of vibration reduction and noise reduction.

[0059] like Figure 1 As shown, the vibration-damping foot pad of Embodiment 1 of the present invention includes a support cylinder 10, a first vibration-damping ring wall 20, and a connecting body 30, which constitute the core components of the vibration-damping foot pad. The support cylinder 10 has a first end 11 for connecting to a fixed mounting surface and a second end 12 opposite to the first end 11. The first vibration-damping ring wall 20 has a first inner ring periphery 21 and a first outer ring periphery 22 surrounding the first inner ring periphery 21. The first outer ring periphery 22 is connected to the second end 12. The wall surface of the first vibration-damping ring wall 20 is inclined from the first outer ring periphery 22 to the first inner ring periphery 21 in a direction away from the first end 11. The first vibration-damping ring wall 20 is capable of elastic deformation (i.e., the first vibration-damping ring wall 20 is elastic). The first vibration-damping ring wall 20 is a flexible body capable of elastic deformation. The connecting body 30... Connected to the periphery 21 of the first inner ring, the connecting body 30 has an annular groove 31 for mounting the foot of the vibrator 100. The connecting body 30 is provided with a limiting ring platform 32, which is located between the annular groove 31 and the first damping ring wall 20. There is a gap between the limiting ring platform 32 and the first damping ring wall 20, and the limiting ring platform 32 is used to abut against the foot of the vibrator 100. The support cylinder 10, the first damping ring wall 20 and the connecting body 30 are provided with a through hole 1 that extends in the axial direction. The through hole 1 is used to pass through the fastener that fixes the foot of the vibrator 100 to the fixed mounting surface.

[0060] The vibration damping pads provided in this embodiment of the invention are used to install and fix the vibrator 100 on the fixed mounting surface. During assembly, the bottom foot of the vibrator 100 is fitted into the annular groove 31 of the connecting body 30, and the limiting ring platform 32 supports the bottom foot of the vibrator 100. Then, the fastener passes through the through hole 1 and is connected to the fixed mounting surface. After assembly, since the wall surface of the first vibration damping ring wall 20 is inclined from the periphery 22 of the first outer ring to the periphery 21 of the first inner ring away from the first end 11, and the first vibration damping ring wall 20 can generate elastic deformation in the axial direction, under the action of the gravity of the vibrator 100, the first vibration damping ring wall 20 undergoes elastic deformation in the axial direction and sinks, thereby enabling the vibrator 100 to be balanced and fixedly connected to the fixed mounting surface. During the vibration energy generated by the operation of the vibrating body 100, the vibration energy is first transferred to the connecting body 30, and then to the first damping ring wall 20. Under the action of the vibration energy, the first damping ring wall 20 undergoes further elastic deformation (at this time, the first damping ring wall 20 undergoes complex deformation with multiple degrees of freedom superimposed in the axial, circumferential, and radial directions under the excitation of the vibration energy), thereby converting the vibration energy into the deformation potential energy and thermal internal energy of the first damping ring wall 20. In this way, the vibration energy is effectively reduced to the fixed mounting surface, and the noise generated by the vibration of the fixed mounting surface due to the excitation of the vibration energy is reduced, thereby achieving the effect of noise reduction.

[0061] Specifically, the vibration damping pad of Embodiment 1 of the present invention is a flexible component integrally molded from rubber material. That is, the entire vibration damping pad can undergo elastic deformation (i.e., the vibration damping pad is elastic). For example, the limiting ring platform 32 that supports the bottom foot of the vibrating body 100 can also undergo elastic deformation under the excitation of the vibration energy generated by the vibrating body 100. That is, the limiting ring platform 32 also converts part of the vibration energy into deformation potential energy and thermal internal energy, thereby helping to achieve the purpose of noise reduction.

[0062] In the vibration damping pad of Embodiment 1, the axial projected area of ​​the limiting ring platform 32 is smaller than the axial projected area of ​​the first vibration damping ring wall 20. Thus, when the first vibration damping ring wall 20 deforms to its limit along the axial direction, the limiting ring platform 32 abuts against the wall surface of the first vibration damping ring wall 20. Since both the limiting ring platform 32 and the first vibration damping ring wall 20 are flexible components capable of elastic deformation, the limiting ring platform 32 can prevent the bottom of the rigid vibrating body 100 from directly abutting against the wall surface of the first vibration damping ring wall 20, thereby preventing damage to the first vibration damping ring wall 20 and ensuring its integrity. In this way, the first vibration damping ring wall 20 can restore its normal vibration damping capacity after the vibration excitation of the vibrating body 100 is removed or reduced. Furthermore, by utilizing the cooperation between the limiting ring platform 32 and the first damping ring wall 20, the maximum stroke of the connecting body 30 in the axial direction can be limited. That is, the maximum stroke of the connecting body 30 in the axial direction is less than the height of the support cylinder 10. In this way, when the connecting body 30 vibrates and sinks to the limit position under the excitation of the vibration energy of the vibrating body 100, the limiting ring platform 32 abuts against the wall surface of the first damping ring wall 20, so that the connecting body 30 will not directly abut against the fixed mounting surface, and the vibration energy will not be transmitted to the fixed mounting surface, thus preventing the wall surface from being excited by the vibration energy and generating noise.

[0063] Specifically, in order to enhance the mechanical strength of the support cylinder 10, that is, to enhance the supporting stiffness of the support cylinder 10 for the vibrating body 100, a boss structure 80 is provided on the support cylinder 10. The boss structure 80 is used to enhance the supporting stiffness of the support cylinder 10. For example... Figure 1 As shown, the boss structure 80 is at least one annular boss 81 arranged circumferentially on the inner and / or outer sidewalls of the support cylinder 10. In the vibration damping pad of Embodiment 1 of the present invention, the number of annular bosses 81 is one, and the side end face of the annular boss 81 facing away from the connector 30 is flush with the end face of the first end 11. The side end face of the annular boss 81 facing away from the connector 30 and the end face of the first end 11 simultaneously abut against the fixed mounting surface, increasing the contact area between the vibration damping pad and the fixed mounting surface, so that the vibration damping pad can be installed more stably on the fixed mounting surface.

[0064] Furthermore, there is a gap between the fastener inserted in the through hole 1 and at least a portion of the hole wall of the through hole 1, that is, there is a clearance fit between the fastener and the through hole 1. In this way, when the vibrating body 100 generates vibration energy excitation during operation, the fastener can be buffered in the gap between the fastener and the hole wall of the through hole 1 during the vibration displacement of the vibrating body 100 in the circumferential and radial directions, and then the fastener transmits the vibration energy to the connecting body 30 in the circumferential and radial directions.

[0065] Example 2:

[0066] like Figure 2 As shown, this illustrates the structure of the vibration-damping foot pad provided in Embodiment 2 of the present invention. Compared with the vibration-damping foot pad of Embodiment 1, the vibration-damping foot pad of Embodiment 2 has the following differences.

[0067] In the vibration damping pad of Embodiment 2, the vibration damping pad further includes a protective bushing 90, which is disposed in the through hole 1 and is used to pass through the fastener. Thus, the fastener and the vibration damping pad are separated by the protective bushing 90, preventing the threads of the fastener from directly contacting the wall of the through hole 1. This avoids the fastener rigidly abutting against the wall of the through hole 1 when the vibrator 100 generates vibration energy, thereby protecting the vibration damping pad from damage by the threads of the fastener and further extending the service life of the vibration damping pad.

[0068] During assembly, there is a gap between the circumferential outer wall of the protective bushing 90 and at least a portion of the hole wall of the through hole 1, that is, the protective bushing 90 and the through hole 1 are clearance fit. In this way, when the vibrating body 100 generates vibration energy excitation during operation, the fastener can be buffered in the gap between the protective bushing 90 and the hole wall of the through hole 1 during the vibration displacement of the vibrating body 100 in the circumferential and radial directions, and then the fastener transmits the vibration energy to the connecting body 30 in the circumferential and radial directions.

[0069] Alternatively, during assembly, the circumferential outer wall of the protective bushing 90 and at least a portion of the hole wall of the through hole 1 are interference fit or transition fit, and there is a gap between the fastener passing through the protective bushing 90 and the hole wall of the through hole in the protective bushing 90, that is, there is a clearance fit between the fastener and the protective bushing 90. In this way, when the vibrator 100 generates vibration energy excitation during operation, the fastener can buffer the displacement in the gap between the fastener and the protective bushing 90 during the vibration displacement of the vibrator 100 in the circumferential and radial directions, and then the fastener transmits the vibration energy to the connector 30 in the circumferential and radial directions.

[0070] Alternatively, during assembly, there may be a gap between the circumferential outer wall of the protective bushing 90 and at least a portion of the hole wall of the through hole 1, and a gap between the fastener passing through the protective bushing 90 and the hole wall of the through hole in the protective bushing 90. In other words, the protective bushing 90 and the through hole 1 are clearance-fitted, and the fastener and the protective bushing 90 are clearance-fitted. Thus, when the vibrator 100 generates vibration energy, the fastener, following the vibration displacement of the vibrator 100 in the circumferential and radial directions, can buffer the displacement within the gaps between the fastener and the protective bushing 90 and between the protective bushing 90 and the hole wall of the through hole 1. Only then can the fastener transmit the vibration energy to the connector 30 in the circumferential and radial directions.

[0071] Specifically, the protective bushing 90 can be a flexible component molded from rubber or a rigid component molded from a rigid material. Furthermore, the protective bushing 90 is preferably a sleeve with a cylindrical outer wall in the circumferential direction.

[0072] Compared with the vibration damping pad of Example 1, the vibration damping pad of Example 2 is the same in all aspects except for the above-mentioned structural differences, so it will not be described again here.

[0073] Example 3:

[0074] like Figure 3 As shown, this illustrates the structure of the vibration-damping foot pad provided in Embodiment 3 of the present invention. Compared with the vibration-damping foot pad of Embodiment 2, the vibration-damping foot pad of Embodiment 3 has the following differences.

[0075] In the vibration-damping foot pad of Embodiment 3, the support cylinder 10 is provided with a plurality of circumferentially distributed first adjustment holes 14, each of which extends in the axial direction. The first adjustment holes 14 are evenly distributed in the circumferential direction. By providing the first adjustment holes 14 on the support cylinder 10, the support stiffness of the support cylinder 10 can be adjusted, and the overall weight of the vibration-damping foot pad can be reduced.

[0076] Furthermore, the annular boss 81 is provided with circumferentially distributed second adjustment holes 814, each of which extends along the axial direction. The second adjustment holes 814 are evenly distributed along the circumferential direction. By providing the second adjustment holes 814 on the annular boss 81, the stiffness of the annular boss 81 is adjusted, allowing the stiffness of the annular boss 81 to better match the support stiffness of the support cylinder 10. Additionally, the second adjustment holes 814, together with the first adjustment holes 14, reduce the overall weight of the adjustable vibration damping pad.

[0077] like Figure 3As shown, at least one annular adjustment groove 13 is provided circumferentially on the inner and / or outer sidewalls of the support cylinder 10. In Embodiment 3, there is one annular adjustment groove 13, which is provided on the inner sidewall of the support cylinder 10. By providing an annular adjustment groove 13 on the support cylinder 10, the support stiffness of the support cylinder 10 can be further adjusted, and at the same time, the overall weight of the adjustable vibration damping pad can be further reduced.

[0078] like Figure 3 As shown, the diameter of the cross-sectional profile of the annular adjustment groove 13 is d1, the diameter of the through hole 1 corresponding to the support cylinder 10 is D1, and the diameter of the outer circle of the cross-section of the support cylinder 10 is D2. Then, 0 < d1 < D2 - D1. In this way, while ensuring that the support cylinder 10 has sufficient support rigidity, the overall weight of the adjustment damping pad can be further reduced, and the material usage of the damping pad can be saved.

[0079] Compared with the vibration damping pad of Example 2, the vibration damping pad of Example 3 is the same in all aspects except for the above-mentioned structural differences, so it will not be described again here.

[0080] Example 4:

[0081] like Figure 4 As shown, this illustrates the structure of the vibration-damping foot pad provided in Embodiment 4 of the present invention. Compared with the vibration-damping foot pad of Embodiment 2, the vibration-damping foot pad of Embodiment 4 has the following differences.

[0082] In the vibration-damping foot pad of Embodiment 4, the annular boss 81 includes a first ring segment 811, a second ring segment 812, and a third ring segment 813. The first ring segment 811 is connected to the end of the second ring segment 812 facing away from the connecting body 30, and the third ring segment 813 is connected to the end of the second ring segment 812 facing the connecting body 30. The first ring segment 811 and the third ring segment 813 are respectively located on both sides of the second ring segment 812. The first ring segment 811 is connected to the inner wall of the support cylinder 10. That is, the cross-sectional profile of the annular boss 81 in Embodiment 4 is Z-shaped (e.g., ...). Figure 4 As shown), even if the overall weight of the damping pad is the same as or slightly smaller than that of the damping pad in Embodiment 2 (the overall weight of the damping pad in Embodiment 4 is slightly smaller mainly because the weight of the annular boss 81 is further reduced), the stiffness of the annular boss 81 itself can be further improved, thereby assisting in adjusting the support stiffness of the support cylinder 10.

[0083] Compared with the vibration damping pad of Example 2, the vibration damping pad of Example 4 is the same in all aspects except for the above-mentioned structural differences, so it will not be described again here.

[0084] Furthermore, in the vibration-damping foot pad of Embodiment 4, unlike the vibration-damping foot pad of Embodiment 3, the first ring segment 811 of the annular boss 81 is provided with circumferentially distributed second adjustment holes 814, each of the second adjustment holes 814 extending in the axial direction. In addition, multiple circumferentially distributed second adjustment holes 814 may also be provided on the second ring segment 812 and / or the third ring segment 813.

[0085] Compared with the vibration damping pad of Example 3, the vibration damping pad of Example 4 is the same in all aspects except for the above-mentioned structural differences, so it will not be described again here.

[0086] Example 5:

[0087] like Figure 5 As shown, this illustrates the structure of the vibration-damping foot pad provided in Embodiment 5 of the present invention. Compared with the vibration-damping foot pad of Embodiment 1, the vibration-damping foot pad of Embodiment 5 has the following differences.

[0088] In the vibration-damping pad of Embodiment 5, the boss structure 80 consists of multiple strip-shaped bosses 82 disposed on the outer side wall of the support cylinder 10, each of which extends axially. Furthermore, the multiple strip-shaped bosses 82 are evenly spaced and distributed circumferentially on the outer wall of the support cylinder 10. By providing multiple strip-shaped bosses 82 on the support cylinder 10, the supporting rigidity of the support cylinder 10 is enhanced. The end face of each strip-shaped boss 82 facing away from the connector 30 is flush with the end face of the first end 11 of the support cylinder 10, increasing the contact area between the vibration-damping pad and the fixed mounting surface, allowing the vibration-damping pad to be installed more stably on the fixed mounting surface.

[0089] Compared with the vibration damping pad of Example 1, the vibration damping pad of Example 5 is the same in all aspects except for the above-mentioned structural differences, so it will not be described again here.

[0090] Example 6:

[0091] like Figure 6 As shown, this illustrates the structure of the vibration-damping foot pad provided in Embodiment Six of the present invention. Compared with the vibration-damping foot pad of Embodiment Five, the vibration-damping foot pad of Embodiment Six has the following differences.

[0092] In the vibration-damping pad of Embodiment Six, the boss structure 80 consists of multiple strip-shaped bosses 82 disposed on the inner sidewall of the support cylinder 10, each of which extends axially. Furthermore, the multiple strip-shaped bosses 82 are evenly spaced and distributed circumferentially on the inner wall of the support cylinder 10. By providing multiple strip-shaped bosses 82 on the support cylinder 10, the supporting rigidity of the support cylinder 10 is enhanced. The end face of each strip-shaped boss 82 facing away from the connector 30 is flush with the end face of the first end 11 of the support cylinder 10, increasing the contact area between the vibration-damping pad and the fixed mounting surface, allowing the vibration-damping pad to be installed more stably on the fixed mounting surface.

[0093] Compared with the vibration damping pad of Example 5, the vibration damping pad of Example 6 is the same in all aspects except for the above-mentioned structural differences, so it will not be described again here.

[0094] Example 7:

[0095] like Figure 7 As shown, this illustrates the structure of the vibration-damping foot pad provided in Embodiment Seven of the present invention. Compared with the vibration-damping foot pad of Embodiment Six, the vibration-damping foot pad of Embodiment Seven has the following differences.

[0096] In the vibration-damping pad of Embodiment Seven, the plurality of strip-shaped protrusions 82 are divided into multiple groups. In each group, the strip-shaped protrusions 82 are evenly distributed circumferentially. In adjacent groups, the strip-shaped protrusions 82 extend coaxially in the axial direction and are spaced apart, thereby enhancing the support rigidity of the support cylinder 10. Among them, in the group of strip-shaped protrusions 82 facing away from the connector 30, the end face of each strip-shaped protrusion 82 facing away from the connector 30 is flush with the end face of the first end 11 of the support cylinder 10, which increases the contact area between the vibration-damping pad and the fixed mounting surface, so that the vibration-damping pad can be installed more stably on the fixed mounting surface.

[0097] Compared with the vibration damping pad of Example 6, the vibration damping pad of Example 7 is the same in all aspects except for the above-mentioned structural differences, so it will not be described again here.

[0098] Example 8:

[0099] like Figure 8 As shown, this illustrates the structure of the vibration-damping foot pad provided in Embodiment 8 of the present invention. Compared with the vibration-damping foot pad of Embodiment 1, the vibration-damping foot pad of Embodiment 8 has the following differences.

[0100] In the vibration-damping foot pad of Embodiment 8, the vibration-damping foot pad further includes at least one vibration-damping sub-ring wall 40. The vibration-damping sub-ring wall 40 has a second inner ring periphery 41 and a second outer ring periphery 42 surrounding the second inner ring periphery 41. The second outer ring periphery 42 is connected to the first inner ring periphery 21 (the second outer ring periphery 42 can be directly connected to the first inner ring periphery 21 or indirectly connected to the first inner ring periphery 21). The connecting body 30 is directly connected to the second inner ring periphery 41. The vibration-damping sub-ring wall 40 is inclined from the second outer ring periphery 42 to the second inner ring periphery 41 in a direction away from the first end 11. Furthermore, the vibration-damping sub-ring wall 40 is capable of elastic deformation, that is, the vibration-damping sub-ring wall 40 is elastic.

[0101] After the vibrator 100 is installed on the vibration damping pad, under the gravity of the vibrator 100, the first vibration damping ring wall 20 and the vibration damping sub-ring wall 40 both undergo elastic deformation and sink in the axial direction, so that the vibrator 100 can be fixedly connected to the fixed mounting surface in a balanced manner.

[0102] During the process of vibration energy generated by the operation of the vibrating body 100, the vibration energy is first transferred to the connecting body 30, and then to the damper ring wall 40. At this time, the damper ring wall 40 undergoes further elastic deformation under the action of vibration energy (at this time, the damper ring wall 40 undergoes complex deformation with multiple degrees of freedom superimposed in the axial, circumferential and radial directions under the excitation of vibration energy), thereby converting the vibration energy (all or most of the vibration energy) into the deformation potential energy and thermal internal energy of the damper ring wall 40, reducing the noise generated by the vibration of the fixed installation surface due to the excitation of vibration energy, and achieving the effect of noise reduction.

[0103] When the vibration damper ring wall 40 vibrates and sinks to its travel limit along the axial direction, the vibration energy generated by the vibrator 100 will continue to be transmitted to the first vibration damper ring wall 20. Under the action of the vibration energy, the first vibration damper ring wall 20 undergoes further elastic deformation (at this time, the first vibration damper ring wall 20 undergoes complex deformation with multiple degrees of freedom superimposed in the axial, circumferential, and radial directions under the excitation of the vibration energy), thereby converting the vibration energy into the deformation potential energy and thermal internal energy of the first vibration damper ring wall 20. In this way, the vibration energy transmitted to the fixed mounting surface is effectively reduced, and the noise generated by the vibration of the fixed mounting surface due to the excitation of the vibration energy is reduced, thereby achieving the effect of noise reduction.

[0104] Therefore, the damping ring wall 40 cooperates with the first damping ring wall 20 to convert the vibration energy generated by the vibrating body 100 into deformation potential energy and thermal internal energy, thereby reducing the noise generated by the vibration energy excitation of the fixed mounting surface.

[0105] When there is only one vibration damping ring wall 40, the vibration damping foot pad also includes a transition support cylinder 50. There is only one transition support cylinder 50, one end of which is connected to the periphery 21 of the first inner ring, and the other end of which is connected to the periphery 42 of the second outer ring. Furthermore, the axial projected area of ​​the limiting ring platform 32 is smaller than the axial projected area of ​​the vibration damping ring wall 40. Thus, when the vibration damping ring wall 40 deforms downwards along the axial direction to its limit, the limiting ring platform 32 abuts against the wall surface of the vibration damping ring wall 40. Since both the limiting ring platform 32 and the vibration damping ring wall 40 are flexible components capable of elastic deformation, the limiting ring platform 32 can prevent the bottom foot of the rigid vibrating body 100 from directly abutting against the wall surface of the vibration damping ring wall 40, thereby preventing damage to the vibration damping ring wall 40 and ensuring its integrity.

[0106] Alternatively, when there are multiple vibration damping ring walls 40, the vibration damping pad further includes multiple transition support cylinders 50. Each transition support cylinder 50 corresponds one-to-one with a specific vibration damping ring wall 40. The first vibration damping ring wall 20 and its adjacent vibration damping ring wall 40 are connected by a transition support cylinder 50 (i.e., the first inner ring periphery 21 is connected to one end of the transition support cylinder 50, and the second outer ring periphery 42 of the vibration damping ring wall 40 adjacent to the first vibration damping ring wall 20 is connected to the transition support cylinder 50). The other end of 0 is connected), and two adjacent damping ring walls 40 are connected by a transition support cylinder 50 (the second inner ring periphery 41 of the damping ring wall 40 near the first damping ring wall 20 is connected to one end of the transition support cylinder 50, and the second outer ring periphery 42 of the damping ring wall 40 away from the first damping ring wall 20 is connected to the other end of the transition support cylinder 50). Along the direction from the first damping ring wall 20 to the damping ring wall 40, the axial projection area of ​​each damping ring wall 40 decreases sequentially. Furthermore, the axial projection area of ​​the limiting ring platform 32 is smaller than the axial projection area of ​​the damping ring wall 40 connected to the connecting body 30. Thus, when the damping ring wall 40 connected to the connecting body 30 sinks and deforms to its limit in the axial direction, the limiting ring platform 32 abuts against the wall surface of the damping ring wall 40 connected to the connecting body 30. Since both the limiting ring platform 32 and the damping ring wall 40 are flexible components capable of elastic deformation, the limiting ring platform 32 can prevent the bottom foot of the rigid vibrating body 100 from directly abutting against the wall surface of the damping ring wall 40 connected to the connecting body 30, thereby preventing damage to the damping ring wall 40 and ensuring the integrity of the damping ring wall 40.

[0107] Compared with the vibration damping pad of Example 1, the vibration damping pad of Example 8 is the same in all aspects except for the above-mentioned structural differences, so it will not be described again here.

[0108] Example 9:

[0109] like Figure 9 As shown, this illustrates the structure of the vibration-damping foot pad provided in Embodiment Nine of the present invention. Compared with the vibration-damping foot pad of Embodiment One, the vibration-damping foot pad of Embodiment Nine has the following differences.

[0110] In the vibration-damping foot pad of Embodiment Nine, the vibration-damping foot pad further includes a second vibration-damping ring wall 60 and a bottom support platform 71. The second vibration-damping ring wall 60 has an inner edge 61 and an outer edge 62 surrounding the inner edge 61. The outer edge 62 is connected to the first end 11. The inner edge 61 is connected to one end of the bottom support platform 71 (the inner edge 61 and the bottom support platform 71 can be directly connected, or the inner edge 61 is indirectly connected to the bottom support platform 71). The other end of the bottom support platform 71 is used to support the fixed mounting surface. The inclination direction of the wall surface of the second vibration-damping ring wall 60 is opposite to the inclination direction of the wall surface of the first vibration-damping ring wall 20. The second vibration-damping ring wall 60 can produce elastic deformation (i.e., the second vibration-damping ring wall 60 is elastic). The bottom support platform 71 has a perforation opposite to the through hole 1.

[0111] During the process of vibration energy generated by the operation of the vibrating body 100, the vibration energy is first transmitted to the connecting body 30, and then to the first damping ring wall 20. Under the action of vibration energy, the first damping ring wall 20 undergoes further elastic deformation (at this time, the first damping ring wall 20 undergoes complex deformation with multiple degrees of freedom superimposed in the axial, circumferential and radial directions under the excitation of vibration energy), thereby converting the vibration energy into the deformation potential energy and thermal internal energy of the first damping ring wall 20, reducing the noise generated by the vibration of the fixed mounting surface due to the excitation of vibration energy. When the first damping ring wall 20 vibrates and sinks to its travel limit along the axial direction, the vibration energy generated by the vibrating body 100 will continue to be transmitted to the second damping ring wall 60. Under the action of vibration energy, the second damping ring wall 60 undergoes further elastic deformation (at this time, the second damping ring wall 60 undergoes complex deformation with multiple degrees of freedom superimposed in the axial, circumferential, and radial directions under the excitation of vibration energy), thereby further converting the vibration energy into the deformation potential energy and thermal internal energy of the second damping ring wall 60. In this way, the vibration energy transmitted to the fixed mounting surface is effectively reduced, and the noise generated by the vibration of the fixed mounting surface due to the excitation of vibration energy is reduced, thereby achieving the effect of noise reduction.

[0112] The axial projected area of ​​the bottom support platform 71 is smaller than the axial projected area of ​​the second damping ring wall 60. Thus, when the second damping ring wall 60 vibrates and sinks to its travel limit along the axial direction, its surface abuts against the bottom support platform 71. Because the second damping ring wall 60 can undergo elastic deformation, there is still a displacement distance equal to the height of the bottom support platform 71 after the surface of the second damping ring wall 60 abuts against the bottom support platform 71, thus buffering the vibration and reducing the noise generated by the first end 11 directly colliding with the fixed mounting surface.

[0113] Alternatively, the axial projected area of ​​the bottom support platform 71 is larger than the axial projected area of ​​the second damping ring wall 60. In this way, when the second damping ring wall 60 vibrates and sinks to its travel limit along the axial direction, the first end 11 abuts against the bottom support platform 71, reducing the noise generated by the first end 11 directly colliding with the fixed mounting surface.

[0114] The vibration damping pad also includes a bottom connecting cylinder 72, one end of which is connected to the inner edge 61, and the other end of which is connected to the bottom support platform 71. The axial projection area of ​​the bottom connecting cylinder 72 is smaller than the axial projection area of ​​the bottom support platform 71.

[0115] Compared with the vibration damping pad of Example 1, the vibration damping pad of Example 9 is the same in all aspects except for the above-mentioned structural differences, so it will not be described again here.

[0116] According to another aspect of the present invention, a temperature control device (not shown) is provided. In this embodiment, the temperature control device may be a refrigerator, an air conditioner, etc. Specifically, the temperature control device includes a housing, a compressor, and vibration damping pads as described above. That is, the compressor is the aforementioned vibrating body 100, and the housing is the aforementioned fixed mounting surface. The housing is provided with an mounting space, the compressor is mounted in the mounting space, and the vibration damping pads are provided between the base of the compressor and the housing.

[0117] The compressor is installed and fixed inside the housing using the vibration-damping pads provided in this embodiment of the invention. During assembly, the compressor's feet are fitted into the annular groove 31 of the connecting body 30, and the limiting ring platform 32 supports the compressor's feet. Then, fasteners are passed through the through hole 1 and connected to the housing. After assembly, the vibration energy is converted into the deformation potential energy and thermal internal energy of the first vibration-damping ring wall 20, the vibration-damping sub-ring wall 40, and the second vibration-damping ring wall 60, etc. This effectively reduces the transmission of vibration energy to the housing, reduces the noise generated by the vibration of the housing due to vibration energy excitation, and thus achieves the effect of noise reduction.

[0118] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the embodiments of the present application should be included within the protection scope of the present application.
