Description

Damping callus on sole and control by temperature change equipment

Technical Field

The application belongs to the technical field of vibration reduction, and particularly relates to a vibration reduction foot pad and temperature control equipment.

Background

The compressor is a core component of a refrigerating system of a refrigerator and is also a main vibration source of the refrigerating system.

In order to attenuate vibration energy generated by a compressor, the prior vibration attenuation aiming at the compressor in a refrigerator mainly realizes circumferential weak constraint and axial weak constraint on the compressor by a vibration attenuation foot pad, thereby realizing vibration energy attenuation generated by vibration of the compressor.

However, since the lower half structure of the vibration damping foot pad of the prior art has a small compressible amount in the circumferential and axial directions, the vibration energy attenuation degree in the circumferential and axial directions of the compressor is limited, and the vibration during actual operation is still large. When the compressor generates high-frequency intense vibration in the working process, the compressor generates more intense vibration excitation, the vibration-damping foot pad is compressed to the limit (the vibration-damping foot pad is pressed down) under the action of axial direction force and tangential force, vibration energy is directly transmitted to the refrigerator body of the refrigerator and also transmitted to a pipeline of the compressor, so that noise and vibration exceed standard, and even the vibration-damping foot pad is damaged in severe cases.

Embodiment one:

the first embodiment of the present invention provides a vibration damping foot pad for fixing the vibration body 100 on a fixed mounting surface (the fixed mounting surface is the ground when the vibration body 100 is directly mounted on the ground, the fixed mounting surface is the table surface of a working platform when the vibration body 100 is mounted on the working platform, the fixed mounting surface is the inner side wall of the equipment shell when the vibration body 100 is mounted in the equipment shell, etc.), and in the process of operating the vibration body 100, the vibration of the vibration body 100 is generated and then transmitted to the vibration foot pad, and the vibration mechanical energy generated by the vibration body 100 is converted by the vibration foot pad to realize the purpose of vibration damping and noise reduction.

As shown in fig. 1, the vibration damping foot pad according to the first embodiment of the present invention includes a support cylinder 10, a first vibration damping annular wall 20, and a connecting body 30, which constitute a core component 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 annular wall 20 has a first inner annular periphery 21 and a first outer annular periphery 22 surrounding the first inner annular periphery 21, the first outer annular periphery 22 is connected with the second end 12, the wall surface of the first vibration damping annular wall 20 is obliquely arranged from the first outer annular periphery 22 to the first inner annular periphery 21 in a direction away from the first end 11, the first vibration damping annular wall 20 can generate elastic deformation (namely, the first vibration damping annular wall 20 has elasticity), the first vibration damping annular wall 20 is a flexible body capable of generating elastic deformation, the connecting body 30 is connected to the first inner annular periphery 21, an annular groove 31 for mounting the foot of the vibration body 100 is formed in the connecting body 30, a limiting annular table 32 is arranged between the annular groove 31 and the first annular wall 20, the foot 32 is abutted against the first vibration damping annular wall 20, a through hole is formed between the first vibration damping annular wall 20 and the vibration damping annular groove 100, and the vibration damping annular wall 20 is used for fixing the vibration damping annular wall 1, and the vibration damping annular wall 1 is penetrated through the supporting the vibration damping annular wall 1, and the vibration damping annular wall 20 is penetrated by the axial through the fixing hole 1.

When the vibration damping foot pad provided by the embodiment of the invention is applied to mount and fix the vibration body 100 on a fixed mounting surface, the foot of the vibration body 100 is sleeved in the annular groove 31 of the connecting body 30 during assembly, the foot of the vibration body 100 is supported by the limiting ring table 32, and then a fastener is penetrated through the through hole 1 and connected to the fixed mounting surface. After the assembly, since the wall surface of the first vibration-damping annular wall 20 is disposed obliquely from the first outer circumferential edge 22 to the first inner circumferential edge 21 in a direction away from the first end 11, and the first vibration-damping annular wall 20 is capable of being elastically deformed in the axial direction, the first vibration-damping annular wall 20 is elastically deformed in the axial direction to sink under the gravity of the vibrator 100, so that the vibrator 100 can be fixedly connected to the fixed mounting surface in a balanced manner. In the process of generating vibration energy by the operation of the vibration body 100, the vibration energy is firstly transferred to the connector 30 and then transferred to the first vibration reduction annular wall 20, and the first vibration reduction annular wall 20 is further elastically deformed under the action of the vibration energy (at this time, the first vibration reduction annular wall 20 is subjected to complex deformation of axial direction, circumferential direction and radial direction with multiple degrees of freedom overlapped under the excitation of the vibration energy), so that the vibration energy is converted into deformation potential energy and thermal energy of the first vibration reduction annular wall 20, and thus, the vibration energy is effectively reduced and transferred to the fixed mounting surface, noise generated by vibration due to the excitation of the vibration energy by the fixed mounting surface is reduced, and the effects of noise elimination and noise reduction are realized.

Specifically, the vibration damping foot pad of the first embodiment of the present invention is integrally formed as an integral flexible member made of rubber, that is, the vibration damping foot pad can be elastically deformed (that is, the vibration damping foot pad has elasticity), for example, the stop collar table 32 supporting the foot of the vibration body 100 can also be elastically deformed under the excitation of the vibration energy generated by the vibration body 100, that is, the stop collar table 32 also converts part of the vibration energy into deformation potential energy and thermal energy, thereby assisting in achieving the purposes of noise elimination and noise reduction.

In the damper foot pad of the first embodiment, the projection area of the stop collar 32 in the axial direction is smaller than the projection area of the first damper annular wall 20 in the axial direction. Thus, when the first vibration-damping annular wall 20 is deformed to limit in the axial direction, the limiting ring table 32 abuts against the wall surface of the first vibration-damping annular wall 20, and the limiting ring table 32 and the first vibration-damping annular wall 20 are flexible components capable of being elastically deformed, so that the limiting ring table 32 can avoid the feet of the rigid vibration body 100 from directly abutting against the wall surface of the first vibration-damping annular wall 20, thereby avoiding damage to the first vibration-damping annular wall 20, ensuring the integrity of the first vibration-damping annular wall 20, and ensuring the normal vibration-damping capability of the first vibration-damping annular wall 20 after the vibration excitation of the vibration body 100 is cancelled or reduced. Moreover, the limit ring table 32 and the first vibration-damping annular wall 20 cooperate to limit the maximum stroke of the connection body 30 in the axial direction, that is, the maximum stroke of the connection body 30 in the axial direction is smaller than the height of the support cylinder 10, so that when the connection body 30 is vibrated to sink to the limit position under the vibration energy excitation of the vibration body 100, the limit ring table 32 abuts against the wall surface of the first vibration-damping annular wall 20, so that the connection body 30 is not directly abutted against the fixed mounting surface, the vibration energy is not transmitted to the fixed mounting surface, and the wall surface excites the fixed mounting surface to generate noise.

Specifically, in order to enhance the mechanical strength of the support cylinder 10, that is, the support rigidity of the support cylinder 10 to the vibrator 100, the support cylinder 10 is provided with a boss structure 80, and the boss structure 80 serves to enhance the support rigidity of the support cylinder 10. As shown in fig. 1, the boss structure 80 is at least one annular boss 81 circumferentially disposed on the inner and/or outer sidewall of the support cylinder 10. In the vibration damping foot pad according to the first embodiment of the present invention, the number of the annular bosses 81 is one, and the side end faces of the annular bosses 81 facing away from the connector 30 are flush with the end face of the first end 11, and the side end faces of the annular bosses 81 facing away from the connector 30 and the end face of the first end 11 simultaneously abut against the fixed mounting surface, so that the contact area between the vibration damping foot pad and the fixed mounting surface is increased, and the vibration damping foot pad can be more stably mounted on the fixed mounting surface.

The fastener penetrating through the through hole 1 and at least part of the wall of the through hole 1 have a clearance therebetween, that is, the fastener is in clearance fit with the through hole 1. In this way, when vibration energy excitation is generated by the operation of the vibrator 100, the fastener follows the vibration displacement of the vibrator 100 in the circumferential direction and the radial direction, and can perform buffer displacement in the gap between the fastener and the wall of the through hole 1, and then the fastener transmits the vibration energy to the connector 30 in the circumferential direction and the radial direction.

Embodiment two:

as shown in fig. 2, the structure of the vibration damping foot pad provided in the second embodiment of the present invention is shown. The vibration damping footpad of the second embodiment has the following differences compared to the vibration damping footpad of the first embodiment.

In the vibration damping foot pad of the second embodiment, the vibration damping foot pad further includes a protection sleeve 90, the protection sleeve 90 is disposed in the through hole 1, and the protection sleeve 90 is used for penetrating the fastener. Thus, the fastening piece is separated from the vibration damping foot pad by the protection bushing 90, so that the thread teeth of the fastening piece are not in direct contact with the hole wall of the through hole 1, and when the vibration body 100 operates to generate vibration energy, the fastening piece is prevented from being rigidly abutted against the hole wall of the through hole 1, so that the vibration damping foot pad is protected from being damaged by the thread teeth of the fastening piece, and the service life of the vibration damping foot pad can be further prolonged.

When assembled, the circumferential outer wall of the protective bush 90 has a clearance with at least part of the wall of the through-hole 1, i.e. the protective bush 90 is in clearance fit with the through-hole 1. In this way, when vibration energy excitation is generated by the operation of the vibrator 100, the fastener follows the vibration displacement of the vibrator 100 in the circumferential direction and the radial direction, and is able to perform a buffer displacement in the gap between the protection bush 90 and the hole wall of the through hole 1, and then the fastener transmits the vibration energy to the connection body 30 in the circumferential direction and the radial direction.

Alternatively, at the time of assembly, the circumferential outer wall of the protection bush 90 is interference fit or transition fit with at least part of the hole wall of the through hole 1, and a clearance is provided between a fastener penetrating the protection bush 90 and the hole wall of the through hole of the protection bush 90, that is, between the fastener and the protection bush 90. In this way, when vibration energy excitation is generated by operation of the vibration body 100, the fastener follows the vibration displacement of the vibration body 100 in the circumferential direction and the radial direction to perform buffer displacement in the gap between the fastener and the protection bush 90, and then the fastener transmits the vibration energy to the connection body 30 in the circumferential direction and the radial direction.

Still alternatively, at the time of assembly, a gap is provided between the circumferential outer wall of the protection bush 90 and at least part of the wall of the through hole 1, and a gap is provided between a fastener penetrating the protection bush 90 and the wall of the hole of the protection bush 90, that is: the protective bush 90 is in clearance fit with the through hole 1, and the fastener is in clearance fit with the protective bush 90. In this way, when vibration energy excitation is generated by the operation of the vibration body 100, the fastener can perform buffer displacement in the gap between the fastener and the protection bush 90 and the gap between the protection bush 90 and the wall of the through hole 1 during vibration displacement of the vibration body 100 in the circumferential direction and the radial direction, and then the fastener transmits the vibration energy to the connection body 30 in the circumferential direction and the radial direction.

Specifically, the protection bush 90 may be a flexible member molded from a rubber material or a rigid member molded from a rigid material. Also, the protection bush 90 is preferably a sleeve whose circumferential outer wall is a cylindrical surface.

Compared with the damping foot pad of the first embodiment, the damping foot pad of the second embodiment has the same structure except for the above structure, and thus will not be described herein.

Embodiment III:

as shown in fig. 3, the structure of the vibration damping foot pad according to the third embodiment of the present invention is shown. The vibration damping footpad of the third embodiment has the following differences compared to the vibration damping footpad of the second embodiment.

In the vibration damping foot pad according to the third embodiment, the support cylinder 10 is provided with a plurality of first adjustment holes 14 distributed circumferentially, and each of the first adjustment holes 14 extends in the axial direction. The respective first regulating holes 14 are uniformly distributed in the circumferential direction. By providing the first adjusting holes 14 on the support cylinder 10, the support rigidity of the support cylinder 10 is adjusted, and the overall weight of the adjustment damper foot pad can be reduced.

Further, the annular boss 81 is provided with second adjusting holes 814 distributed circumferentially, and each second adjusting hole 814 extends in the axial direction. The respective second regulating holes 814 are uniformly distributed in the circumferential direction. The second adjusting holes 814 are formed in the annular boss 81 to adjust the rigidity of the annular boss 81, so that the rigidity of the annular boss 81 can be more matched with the supporting rigidity of the supporting cylinder 10, and the second adjusting holes 814 and the first adjusting holes 14 jointly reduce the overall weight of the damping foot pad.

As shown in fig. 3, at least one annular adjusting groove 13 is formed on the inner side wall and/or the outer side wall of the supporting cylinder 10 along the circumferential direction. In the third embodiment, the number of the annular regulating grooves 13 is one and is opened on the inner side wall of the support cylinder 10. The annular adjusting groove 13 is formed in the supporting cylinder 10, so that the supporting rigidity of the supporting cylinder 10 is further adjusted, and meanwhile, the overall weight of the damping foot pad can be further lightened.

As shown in fig. 3, the diameter of the cross-sectional profile of the annular regulating groove 13 is d ₁ The diameter of the through hole 1 corresponding to the support cylinder 10 is D ₁ The diameter of the cross-section excircle contour of the supporting cylinder 10 is D ₂ 0 < d ₁ ＜D ₂ -D ₁ Thus, on the basis of ensuring that the supporting cylinder 10 has enough supporting rigidity, the whole weight of the damping foot pad can be further lightened and adjusted, and the material consumption of the damping foot pad is saved.

Compared with the vibration damping foot pad of the second embodiment, the vibration damping foot pad of the third embodiment has the same structure except for the above structure, and thus will not be described in detail herein.

Embodiment four:

as shown in fig. 4, the structure of the vibration damping foot pad according to the fourth embodiment of the present invention is shown. The vibration damping footpad of the fourth embodiment has the following differences from the vibration damping footpad of the second embodiment.

In the vibration damping pad according to the fourth embodiment, the annular boss 81 includes a first annular segment 811, a second annular segment 812 and a third annular segment 813, the first annular segment 811 is connected to an end of the second annular segment 812 facing away from the connecting body 30, the third annular segment 813 is connected to an end of the second annular segment 812 facing toward the connecting body 30, the first annular segment 811 and the third annular segment 813 are respectively located on two sides of the second annular segment 812, and the first annular segment 811 is connected to an inner side wall of the supporting cylinder 10. That is, the cross-sectional profile shape of the annular boss 81 of the fourth embodiment is "Z" -shaped (as shown in fig. 4), and thus, even in the case where the entire weight of the vibration damping footpad is the same as or slightly smaller than that of the second embodiment (the entire weight of the vibration damping footpad of the fourth embodiment is slightly smaller mainly in further reducing the weight of the annular boss 81), the rigidity of the annular boss 81 itself can be further improved, thereby assisting in adjusting the support rigidity of the support cylinder 10.

Compared with the vibration damping foot pad of the second embodiment, the vibration damping foot pad of the fourth embodiment has the same structure except for the above structure, and thus will not be described in detail herein.

In the vibration damping pad according to the fourth embodiment, unlike the vibration damping pad according to the third embodiment, second adjustment holes 814 are circumferentially distributed in the first ring segment 811 of the annular boss 81, and each of the second adjustment holes 814 extends in the axial direction. In addition, a plurality of second adjusting holes 814 distributed circumferentially may be formed in the second ring segment 812 and/or the third ring segment 813.

Compared with the vibration damping foot pad of the third embodiment, the vibration damping foot pad of the fourth embodiment has the same structure except for the above structure, and thus will not be described in detail herein.

Fifth embodiment:

as shown in fig. 5, the structure of the vibration damping foot pad provided in the fifth embodiment of the present invention is shown. The vibration damping footpad of the fifth embodiment has the following differences from the vibration damping footpad of the first embodiment.

In the vibration damping pad according to the fifth embodiment, the boss structure 80 is a plurality of bar-shaped bosses 82 provided on the outer sidewall of the support cylinder 10, and each of the bar-shaped bosses 82 extends in the axial direction. And, a plurality of the strip-shaped bosses 82 are uniformly circumferentially distributed on the outer wall of the support cylinder 10 at intervals for one circle, and the support rigidity of the support cylinder 10 is enhanced by providing a plurality of strip-shaped bosses 82 on the support cylinder 10. The end faces of the strip-shaped bosses 82, which deviate from the connecting body 30, are flush with the end face of the first end 11 of the supporting cylinder 10, so that the contact area between the damping foot pad and the fixed mounting surface is increased, and the damping foot pad can be more stably mounted on the fixed mounting surface.

The vibration damping foot pad of the fifth embodiment is identical to the vibration damping foot pad of the first embodiment except for the above-mentioned structure, and thus will not be described in detail herein.

Example six:

as shown in fig. 6, the structure of the vibration damping foot pad according to the sixth embodiment of the present invention is shown. The vibration damping footpad of the sixth embodiment has the following differences compared to the vibration damping footpad of the fifth embodiment.

In the vibration damping pad according to the sixth embodiment, the boss structure 80 is a plurality of bar-shaped bosses 82 provided on the inner side wall of the support cylinder 10, and each of the bar-shaped bosses 82 extends in the axial direction. And, a plurality of the strip-shaped bosses 82 are uniformly circumferentially distributed on the inner wall of the support cylinder 10 at intervals for one circle, and the support rigidity of the support cylinder 10 is enhanced by providing a plurality of strip-shaped bosses 82 on the support cylinder 10. The end faces of the strip-shaped bosses 82, which deviate from the connecting body 30, are flush with the end face of the first end 11 of the supporting cylinder 10, so that the contact area between the damping foot pad and the fixed mounting surface is increased, and the damping foot pad can be more stably mounted on the fixed mounting surface.

The vibration damping foot pad of the sixth embodiment is identical to the vibration damping foot pad of the fifth embodiment except for the above-described structure, and thus will not be described in detail herein.

Embodiment seven:

as shown in fig. 7, the structure of the vibration damping foot pad provided in the seventh embodiment of the present invention is shown. The vibration damping footpad of the seventh embodiment has the following differences compared to the vibration damping footpad of the sixth embodiment.

In the vibration damping foot pad of the seventh embodiment, the plurality of strip-shaped bosses 82 are divided into a plurality of groups, each strip-shaped boss 82 in each group is uniformly circumferentially distributed at intervals for one circle, and each strip-shaped boss 82 in two adjacent groups extends coaxially along the axial direction in a one-to-one correspondence manner and is arranged at intervals, so that the supporting rigidity of the supporting cylinder 10 is enhanced. Among the strip-shaped bosses 82 deviating from the connecting body 30, the end faces of the end parts of the strip-shaped bosses 82 deviating from the connecting body 30 are all flush with the end face of the first end 11 of the supporting cylinder 10, so that the contact area between the damping foot pad and the fixed mounting surface is increased, and the damping foot pad can be more stably mounted on the fixed mounting surface.

The damper foot pad of the seventh embodiment is similar to the damper foot pad of the sixth embodiment except for the above structure, and thus will not be described in detail herein.

Example eight:

as shown in fig. 8, the structure of the vibration damping foot pad according to the eighth embodiment of the present invention is shown. The vibration damping footpad of the eighth embodiment has the following differences compared to the vibration damping footpad of the first embodiment.

In the damper foot pad according to the eighth embodiment, the damper foot pad further includes at least one damper sub-annular wall 40, the damper sub-annular wall 40 has a second inner annular peripheral edge 41 and a second outer annular peripheral edge 42 surrounding the second inner annular peripheral edge 41, the second outer annular peripheral edge 42 is connected to the first inner annular peripheral edge 21 (the second outer annular peripheral edge 42 may be directly connected to the first inner annular peripheral edge 21 or indirectly connected to the first inner annular peripheral edge 21), the connecting body 30 is directly connected to the second inner annular peripheral edge 41, and the damper sub-annular wall 40 is disposed obliquely from the second outer annular peripheral edge 42 to the second inner annular peripheral edge 41 in a direction away from the first end 11. The damper sub-annular wall 40 is elastically deformable, that is, the damper sub-annular wall 40 has elasticity.

After the vibration body 100 is mounted on the vibration-damping foot pad, under the action of gravity of the vibration body 100, the first vibration-damping annular wall 20 and the vibration-damping annular wall 40 are elastically deformed in the axial direction to sink, so that the vibration body 100 can be fixedly connected on the fixed mounting surface in a balanced manner.

In the process of generating vibration energy by the operation of the vibration body 100, the vibration energy is firstly transferred to the connector 30 and then transferred to the vibration damping sub-annular wall 40, at this time, the vibration damping sub-annular wall 40 is further elastically deformed under the action of the vibration energy (at this time, the vibration damping sub-annular wall 40 is subjected to complex deformation of multiple degrees of freedom superposition in the axial direction, the circumferential direction and the radial direction under the excitation of the vibration energy), so that the vibration energy (all or most of the vibration energy) is converted into deformation potential energy and thermal internal energy of the vibration damping sub-annular wall 40, the noise generated by the vibration of the fixed mounting surface due to the excitation of the vibration energy is reduced, and the effects of noise elimination and noise reduction are realized.

When the vibration damper annular wall 40 is vibrated along the axial direction and sunk to the travel limit, the vibration energy generated by the vibration body 100 is continuously transferred to the first vibration damper annular wall 20, and the first vibration damper annular wall 20 is further elastically deformed under the action of the vibration energy (at this time, the first vibration damper annular wall 20 is subjected to complex deformation of multiple degrees of freedom superposition in the axial direction, the circumferential direction and the radial direction under the excitation of the vibration energy), so that the vibration energy is converted into deformation potential energy and thermal internal energy of the first vibration damper annular wall 20, and thus, the vibration energy is effectively reduced and transferred to the fixed mounting surface, and noise generated by vibration when the fixed mounting surface is excited by the vibration energy is reduced, thereby realizing the effects of noise elimination and noise reduction.

Accordingly, the vibration damping sub-annular wall 40 is matched with the first vibration damping annular wall 20, so that vibration energy generated by the vibration body 100 can be converted into deformation potential energy and thermal internal energy, and noise generated by vibration of the fixed mounting surface due to excitation of the vibration energy can be reduced.

When the number of the vibration damping sub-annular walls 40 is one, the vibration damping foot pad further comprises a transition support cylinder 50, wherein the number of the transition support cylinders 50 is one, one end of the transition support cylinder 50 is connected to the first inner annular periphery 21, and the other end of the transition support cylinder 50 is connected to the second outer annular periphery 42. And, the axial direction projected area of spacing ring platform 32 is less than the axial direction projected area of damping sub-rampart 40, so, when damping sub-rampart 40 sinks to the limit along the axial direction, spacing ring platform 32 butt is to damping sub-rampart 40's wall, because spacing ring platform 32 and damping sub-rampart 40 are the flexible part that can elastic deformation, consequently, spacing ring platform 32 can avoid the footing of rigid vibration body 100 to directly support the wall of damping sub-rampart 40 to avoid causing damping sub-rampart 40 to suffer damage, can guarantee the integrality of damping sub-rampart 40.

Alternatively, when the number of the vibration damping sub-annular walls 40 is plural, the vibration damping foot pad further includes a plurality of transition support cylinders 50, the plurality of transition support cylinders 50 are in one-to-one correspondence with the plurality of vibration damping sub-annular walls 40, the first vibration damping annular wall 20 and the vibration damping sub-annular wall 40 adjacent thereto are connected by one transition support cylinder 50 (i.e., the first inner annular periphery 21 is connected to one end of the transition support cylinder 50, the second outer annular periphery 42 of the vibration damping sub-annular wall 40 adjacent to the first vibration damping annular wall 20 is connected to the other end of the transition support cylinder 50), and the adjacent two vibration damping sub-annular walls 40 are connected by one transition support cylinder 50 (the second inner annular periphery 41 of the vibration damping sub-annular wall 40 adjacent to the first vibration damping annular wall 20 is connected to one end of the transition support cylinder 50), the second outer annular periphery 42 of the vibration damping sub-annular wall 40 distant from the first vibration damping annular wall 20 is connected to the other end of the transition support cylinder 50), and the projected area of the vibration damping sub-annular walls 40 in the respective directions of the vibration damping sub-annular walls 40 is sequentially reduced in the axial direction. And, the axial direction projection area of spacing ring platform 32 is less than the axial direction projection area of the damping sub-annular wall 40 that is connected with the connector 30, so, when the damping sub-annular wall 40 that is connected with the connector 30 sinks and warp to the limit along the axial direction, then spacing ring platform 32 butt is on the wall surface of the damping sub-annular wall 40 that is connected with the connector 30, because spacing ring platform 32 and this damping sub-annular wall 40 are flexible part that can elastic deformation, therefore, spacing ring platform 32 can avoid the footing of rigid vibrator 100 to directly support the wall surface of the damping sub-annular wall 40 that is connected with the connector 30 to avoid causing this damping sub-annular wall 40 to suffer damage, can guarantee the integrality of damping sub-annular wall 40.

The vibration damping foot pad of the eighth embodiment is identical to the vibration damping foot pad of the first embodiment except for the above-mentioned structure, and thus will not be described in detail herein.

Example nine:

as shown in fig. 9, a structure of a vibration damping foot pad according to a ninth embodiment of the present invention is shown. The vibration damping footpad of the ninth embodiment has the following differences from the vibration damping footpad of the first embodiment.

In the damper foot pad according to the ninth embodiment, the damper foot pad further includes a second damper annular wall 60 and a bottom support base 71, the second damper annular 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 base 71 (the inner edge 61 and the bottom support base 71 may be directly connected or the inner edge 61 is indirectly connected to the bottom support base 71), the other end of the bottom support base 71 is used for being supported on a fixed mounting surface, the wall surface of the second damper annular wall 60 is inclined in a direction opposite to the wall surface of the first damper annular wall 20, the second damper annular wall 60 is capable of being elastically deformed (i.e., the second damper annular wall 60 has elasticity), and the bottom support base 71 is provided with a through hole opposite to the through hole 1.

In the process of generating vibration energy by the operation of the vibration body 100, the vibration energy is firstly transferred to the connector 30 and then transferred to the first vibration reduction annular wall 20, and the first vibration reduction annular wall 20 is further elastically deformed under the action of the vibration energy (at this time, the first vibration reduction annular wall 20 is subjected to complex deformation of multiple degrees of freedom superposition in the axial direction, the circumferential direction and the radial direction under the excitation of the vibration energy), so that the vibration energy is converted into deformation potential energy and thermal energy of the first vibration reduction annular wall 20, and noise generated by vibration of the fixed mounting surface under the excitation of the vibration energy is reduced. When the first vibration-damping annular wall 20 is vibrated along the axial direction and sunk to the limit of travel, the vibration energy generated by the vibration body 100 is continuously transmitted to the second vibration-damping annular wall 60, and the second vibration-damping annular wall 60 is further elastically deformed under the action of the vibration energy (at this time, the second vibration-damping annular wall 60 is subjected to complex deformation of multiple degrees of freedom superposition in the axial direction, the circumferential direction and the radial direction under the excitation of the vibration energy), so that the vibration energy is further converted into deformation potential energy and thermal internal energy of the second vibration-damping annular wall 60, and therefore, the vibration energy is effectively reduced and transmitted to the fixed mounting surface, and noise generated when the fixed mounting surface is excited by the vibration energy and vibrated is further reduced, and therefore, the effects of noise elimination and noise reduction are achieved.

The axial projection area of the bottom support 71 is smaller than the axial projection area of the second vibration damping annular wall 60. In this way, when the second vibration damping annular wall 60 is vibrated and sunk to the limit of the stroke in the axial direction, the wall surface of the second vibration damping annular wall 60 is abutted against the bottom support table 71, and the second vibration damping annular wall 60 can be elastically deformed, so that the displacement distance of the height of the bottom support table 71 is still present after the wall surface of the second vibration damping annular wall 60 is abutted against the bottom support table 71, thereby damping vibration, and reducing noise generated by the first end 11 directly hitting the fixed mounting surface.

Alternatively, the axial direction projection area of the bottom support table 71 is larger than the axial direction projection area of the second vibration damping annular wall 60. In this way, when the second vibration damping annular wall 60 is vibrated and sunk in the axial direction to the stroke limit, the first end 11 abuts against the bottom support table 71, and noise generated by the first end 11 directly hitting the fixed mounting surface is reduced.

The damping foot pad further comprises a bottom connecting cylinder 72, one end of the bottom connecting cylinder 72 is connected with the inner edge 61, the other end of the bottom connecting cylinder 72 is connected with the bottom supporting table 71, and the axial direction projection area of the bottom connecting cylinder 72 is smaller than that of the bottom supporting table 71.

The vibration damping foot pad of the ninth embodiment is identical to the vibration damping foot pad of the first embodiment except for the above structure, and thus will not be described in detail herein.

The shell is provided with an installation space, the compressor is installed in the installation space, and damping foot pads are arranged between the feet of the compressor and the shell.

The vibration damping foot pad provided by the embodiment of the invention is used for installing and fixing the compressor in the shell, when the vibration damping foot pad is assembled, the foot of the compressor is sleeved in the annular groove 31 of the connecting body 30, the foot of the compressor is supported by the limiting ring table 32, and then the fastening piece penetrates through the through hole 1 and is connected to the shell. After the assembly is completed, the vibration energy is converted into deformation potential energy and thermal internal energy of the first vibration reduction annular wall 20, the vibration reduction annular wall 40, the second vibration reduction annular wall 60 and the like, so that the vibration energy is effectively reduced and transferred to the shell, the noise generated by the vibration of the shell due to the excitation of the vibration energy is reduced, and the effects of noise elimination and noise reduction are realized.
