Description

Technical Field

[0001] This utility model belongs to the field of air conditioner technology, specifically relating to a vibration reduction structure, a compressor, and an air conditioner. Background Technology

[0002] The start-up and shutdown of a compressor generates significant reciprocating vibrations, affecting air conditioner noise and piping reliability. Some of this reciprocating vibration is transmitted to the connecting pipes, the air conditioner panel, and the connecting copper pipes. This vibration transmission produces bothersome low-frequency noise, and the pipes are at risk of fatigue fracture. To reduce compressor vibration, damping washers are used. The lower end of the washer is mounted on the air conditioner base plate, and the upper neck of the washer mates with the compressor's mounting feet. This installation method primarily provides axial support and vibration damping for the mounting feet. Tangential vibration is absorbed only by the thinner wall of the washer in the tangential direction, resulting in poor damping performance. The main vibration of the compressor is tangential, followed by radial and axial vibrations of the compressor body.

[0003] To reduce tangential vibration, the existing method is to arrange two layers of vibration damping washers longitudinally. Tests have shown that this method has a good vibration damping effect, but it is not effective in relieving transportation stress. This is because the double-layer arrangement increases the overall height of the unit and is insufficient in resisting swaying inertia. When transporting the air conditioner on bumpy roads, the compressor will jump significantly inside the air conditioner, and the longitudinal variable displacement range will be too large, causing the pipe deformation to exceed the plastic deformation range, which will lead to the breakage of the copper pipe connected to the compressor. Utility Model Content

[0004] This utility model provides a vibration damping structure, a compressor, and an air conditioner, which can solve the technical problem that the existing method of using double-layer longitudinally arranged vibration damping washers to reduce tangential vibration causes the copper pipes connected to the compressor to break.

The first mounting plate is horizontally arranged, and the second mounting plate is vertically arranged. The first mounting plate is connected to the outer wall surface of the vibrating element. The vibration damping assembly includes a first vibration damper and a second vibration damper.

[0008] In some embodiments, the first mounting plate has a flange on the outer edge of the side wall facing the vibrator, the side wall surface of the flange is arc-shaped, and the side wall surface of the flange is connected to the outer wall surface of the vibrator.

[0009] In some embodiments, the first damping member includes a first elastic member and a first support rod, the first elastic member being sleeved on the first support rod and connected to the first mounting plate.

[0010] In some embodiments, one end of the first support rod is connected to the base plate, and the other end of the first support rod extends out of the first elastic member and is fitted with a locking member, the locking member being used to axially limit the first elastic member.

The arrangement of the first and second mounting plates makes the vibration transmission path clearer. The first mounting plate is horizontally positioned, primarily transmitting axial vibration; the second mounting plate is vertically positioned, primarily transmitting tangential vibration. This arrangement allows vibration to be transmitted to the corresponding damping elements in a predetermined direction. Through the separation of the first and second mounting plates, the vibration is effectively distributed to two different directions. The first damping element absorbs axial vibration, and the second damping element absorbs tangential vibration. This clear division of labor avoids mutual interference between vibrations in different directions, improving damping efficiency. The first and second mounting plates provide a stable support platform for the damping elements. The first mounting plate connects to the compressor's feet, ensuring that axial vibration can be smoothly transmitted to the first damping element; the second mounting plate connects to the outer wall of the compressor, ensuring that tangential vibration can be smoothly transmitted to the second damping element. This synergistic effect allows the damping elements to absorb vibration more effectively. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0022] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used here to describe the spatial positional relationship of a device or feature as shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation of the device as described in the figure. For example, if a device in the figure is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures.

[0023] See also Figures 1 to 9 As shown, according to an embodiment of the present invention, a vibration damping structure is provided, which includes a mounting leg 1 and a vibration damping assembly. The mounting leg 1 includes a first mounting plate 101 and a second mounting plate 102 connected to each other. The first mounting plate 101 is horizontally arranged, and the second mounting plate 102 is vertically arranged. The first mounting plate 101 is connected to the outer wall surface of the vibrating element 4. The vibration damping assembly includes a first damping element 2 and a second damping element 3. The first damping element 2 elastically supports the first mounting plate 101, and the second damping element 3 elastically supports the second mounting plate 102. The first damping element 2 is used to absorb the axial vibration of the vibrating element 4, and the second damping element 3 is used to absorb the tangential vibration of the vibrating element 4. In this embodiment, the vibrating element 4 is a compressor. In other embodiments, the vibration damping structure of this embodiment can also be used for components that generate vibration.

[0024] Specifically, the axial vibration of the compressor is mainly transmitted along the compressor's axis. This vibration is transmitted through the compressor's feet to the first mounting plate 101 of the mounting bracket 1. The tangential vibration of the compressor is mainly transmitted along a direction perpendicular to the compressor's axis. This vibration is transmitted through the compressor's feet to the second mounting plate 102 of the mounting bracket 1. When the compressor generates axial vibration, the vibration is transmitted through the compressor's feet to the first mounting plate 101, where the first damping member 2 (elastically supporting the first mounting plate 101) absorbs this axial vibration. When the compressor generates tangential vibration, the vibration is transmitted through the compressor's feet to the second mounting plate 102, where the second damping member 3 (elastically supporting the second mounting plate 102) absorbs this tangential vibration.

[0025] In this embodiment, the first damping member 2 elastically supports the first mounting plate 101 to absorb the axial vibration of the compressor. Axial vibration is vibration along the compressor axis. If this vibration is directly transmitted to the air conditioner base plate 5, it will cause overall vibration and noise of the air conditioner, and may even affect the structural stability of the air conditioner. Through the elastic support of the first damping member 2, the energy of the axial vibration can be converted into elastic potential energy, thereby effectively attenuating the vibration amplitude and reducing the intensity of vibration transmitted to the air conditioner base plate 5. The second damping member 3 elastically supports the second mounting plate 102 to absorb the tangential vibration of the compressor. Tangential vibration is the main vibration direction of the compressor, and the vibration amplitude is large, which can easily cause fatigue fracture of the connecting pipes and low-frequency noise of the air conditioner panel. Through the elastic support of the second damping member 3, the energy of the tangential vibration can be dispersed and absorbed, reducing the intensity of vibration transmitted to the connecting pipes and the air conditioner panel, thereby reducing the risk of pipe fracture and noise level. This embodiment, by simultaneously setting two damping members to absorb axial and tangential vibrations respectively, can achieve comprehensive vibration reduction in multiple directions. This multi-directional vibration reduction setting can significantly improve the overall vibration reduction effect and reduce the impact of vibration on various components of the air conditioning system. Tangential vibration is the main vibration direction of the compressor, and the vibration amplitude is relatively large. If the tangential vibration is not effectively absorbed, the connecting pipeline will be frequently subjected to vibration impact, which is prone to fatigue fracture. By absorbing tangential vibration through the second damping component 3, the vibration amplitude of the pipeline can be significantly reduced, thereby reducing the risk of pipeline fatigue fracture and improving the reliability and service life of the air conditioning system. Although the traditional double-layer longitudinally arranged damping gasket has a certain damping effect, due to its increased height, it is insufficient to resist swaying inertia, which can easily cause the compressor to jump inside the air conditioner, or even cause the pipeline deformation to exceed the plastic deformation range. In this embodiment, by setting the first damping component 2 and the second damping component 3 respectively, the overall height of the unit will not be increased, and at the same time, it can better resist the swaying inertia during transportation, reduce the jumping amplitude of the compressor, and improve transportation stability.

[0026] In this embodiment, the arrangement of the first mounting plate 101 and the second mounting plate 102 makes the vibration transmission path clearer. The first mounting plate 101 is horizontally positioned and mainly transmits axial vibration; the second mounting plate 102 is vertically positioned and mainly transmits tangential vibration. This arrangement allows vibration to be transmitted to the corresponding damping components in a predetermined direction. Through the separation of the first mounting plate 101 and the second mounting plate 102, the vibration is effectively distributed to two different directions. The first damping component 2 absorbs axial vibration, and the second damping component 3 absorbs tangential vibration. This clear division of labor avoids mutual interference between vibrations in different directions and improves damping efficiency. The arrangement of the first mounting plate 101 and the second mounting plate 102 provides a stable support platform for the damping components. The first mounting plate 101 is connected to the compressor's feet to ensure that axial vibration can be smoothly transmitted to the first damping component 2; the second mounting plate 102 is connected to the outer wall of the compressor to ensure that tangential vibration can be smoothly transmitted to the second damping component 3. This synergistic effect allows the damping components to absorb vibration more effectively.

[0027] It is worth noting that in this embodiment, axial vibration and tangential vibration can occur simultaneously or separately.

[0028] As a specific implementation, the first damper 2 and the second damper 3 can be made of rubber, springs, or other elastic materials, whose elastic properties can effectively reduce the propagation of vibration. Furthermore, the first damper 2 and the second damper 3 can be specifically optimized for vibrations in different directions based on their respective configurations and material properties. For example, the first damper 2 can use materials and structures more suitable for axial vibration absorption, while the second damper 3 can use materials and structures more suitable for tangential vibration absorption. This clearly defined damping configuration can more effectively distribute and absorb vibration energy, improving damping efficiency.

[0029] See also Figures 1 to 4 As shown, the first damping member 2 is vertically arranged and is snapped into the first mounting plate 101; the second damping member 3 is horizontally arranged and is snapped into the second mounting plate 102.

[0030] In this embodiment, the vertically arranged first vibration damper 2 is used to absorb the axial vibration of the compressor, and the horizontally arranged second vibration damper 3 is used to absorb the tangential vibration of the compressor. The vertical and horizontal arrangement allows the vibration dampers to be optimized for axial and tangential vibrations respectively. With a clear setting direction, the transmission paths of vibration in different directions are clearly separated, reducing the coupling of vibration in different directions. This means that axial and tangential vibrations will not interfere with each other, thereby improving the vibration damping efficiency. The first mounting plate 101 and the second mounting plate 102 provide stable support platforms for the first vibration damper 2 and the second vibration damper 3 respectively. The vertically arranged first vibration damper 2 is connected to the first mounting plate 101 by a snap-fit ​​method, ensuring that axial vibration can be smoothly transmitted to the vibration damper. The horizontally arranged second vibration damper 3 is connected to the second mounting plate 102 by a snap-fit ​​method, ensuring that tangential vibration can be smoothly transmitted to the vibration damper. This arrangement can reduce the intensity of vibration transmitted to other components of the air conditioner. By absorbing axial and tangential vibrations respectively, the vibration dampers can effectively reduce the impact of vibration on the air conditioner base plate 5, connecting pipes, and air conditioner panel, thereby improving the overall stability of the air conditioning system. The snap-fit ​​connection makes the installation and removal of vibration dampers more convenient and quick. This connection method does not require complicated tools or fasteners, and can quickly complete the installation and replacement of vibration dampers. The snap-fit ​​connection provides a stable connection, ensuring that the vibration dampers will not loosen or fall off during operation. This connection method can effectively prevent the vibration dampers from shifting due to vibration, thereby ensuring the stability of the vibration damping effect.

[0031] See also Figures 1 to 4 As shown, the outer peripheral wall of the first damper 2 is provided with a first annular groove 201, and the first mounting plate 101 is provided with a first mounting through hole 111. The top end of the first damper 2 passes through the first mounting through hole 111 so that the first mounting plate 101 is engaged in the first annular groove 201. The outer peripheral wall of the second damper 3 is provided with a second annular groove 301, and the second mounting plate 102 is provided with a second mounting through hole 121. One end of the second damper 3 facing the second mounting plate 102 passes through the second mounting through hole 121 so that the second mounting plate 102 is engaged in the second annular groove 301.

[0032] Specifically, the first mounting plate 101 transmits vibration to the top of the first damping member 2. The top of the first damping member 2 passes through the first mounting through hole 111. The vibration energy is transmitted to the first annular groove 201 through the elastic material of the first damping member 2. The elastic properties of the first damping member 2 can effectively buffer axial vibration and reduce the intensity of vibration transmitted to the air conditioning base plate 5. During the transmission process, the vibration energy is absorbed by the elasticity of the first damping member 2 and converted into elastic potential energy, thereby reducing the propagation of vibration. The damping process of tangential vibration is similar.

[0033] In this embodiment, the first annular groove 201 and the second annular groove 301 allow the first mounting plate 101 and the second mounting plate 102 to be respectively snapped onto the vibration damper. This snapping method provides a stable mechanical connection, ensuring that the vibration damper will not loosen or fall off during operation. The snapping method simplifies the installation process, eliminating the need for complex tools or fasteners. During installation, simply align the mounting plate with the annular groove and snap it in; during disassembly, simply remove the mounting plate from the annular groove. The operation is simple and quick. The annular groove allows the vibration damper to better perform its elastic support function. When vibration is transmitted to the vibration damper, the elastic deformation of the annular groove can further absorb vibration energy and reduce vibration propagation. Through the snapping of the annular groove with the mounting plate, the transmission paths of vibration in different directions are clearly separated. Axial vibration is transmitted to the first vibration damper 2 through the first annular groove 201, and tangential vibration is transmitted to the second vibration damper 3 through the second annular groove 301, reducing the coupling of vibration in different directions. The elastic deformation of the annular groove can convert vibration energy into elastic potential energy, thereby reducing the propagation of vibration. This energy conversion process further improves the vibration reduction effect. Through the snap-fit ​​between the annular groove and the mounting plate, vibration can be effectively absorbed and attenuated, reducing the intensity of vibration transmitted to other components of the air conditioner. This design can significantly improve the overall stability of the air conditioning system.

[0034] See also Figures 1 to 4 As shown, the first mounting plate 101 has a flange 103 on the outer edge of the side wall facing the vibrating element 4. The side wall of the flange 103 is arc-shaped, and the vibrating element 4 has a cylindrical structure. The side wall of the flange 103 is connected to the outer wall of the vibrating element 4, specifically, the flange 103 is welded to the vibrating element 4.

[0035] In this embodiment, the arc-shaped sidewall of the flange 103 is tightly fitted to the outer wall of the vibrator 4, providing a larger contact area and a more stable connection. This arrangement ensures a firm connection between the first mounting plate 101 and the vibrator 4, maintaining stability even under vibration. The arc-shaped flange 103 effectively prevents the first mounting plate 101 from loosening or shifting during vibration. This tight fit reduces connection loosening caused by vibration, thereby improving the reliability of the entire vibration damping structure. The arc-shaped flange 103 disperses the stress transmitted by vibration over a larger area, rather than concentrating it in a localized region. This stress dispersion reduces localized stress concentration, thereby lowering the risk of fatigue fracture caused by stress concentration. The tight fit between the arc-shaped flange 103 and the outer wall of the vibrator 4 allows for better absorption and attenuation of vibration energy. During transmission, the vibration is partially absorbed by the arc-shaped structure of the flange 103, reducing the intensity of vibration transmitted to the damper. The flange 103 increases the structural strength of the first mounting plate 101, enabling it to withstand greater vibration and impact. This enhanced structural strength can improve the service life of the entire vibration damping structure. Through stress dispersion and tight fit, the arc flange 103 can reduce the risk of fatigue fracture caused by vibration. This configuration can significantly improve the reliability and durability of the vibration damping structure.

[0036] See also Figures 1 to 4 As shown, the first damping component 2 includes a first elastic element 202 and a first support rod 203. The first elastic element 202 and the first support rod 203 are coaxially and vertically arranged. The first elastic element 202 is sleeved on the first support rod 203. The first elastic element 202 is connected to the first mounting plate 101. Specifically, the outer peripheral wall of the first elastic element 202 is provided with a first annular groove 201. The first elastic element 202 is engaged with the first mounting plate 101. The material of the first elastic element 202 is rubber or a spring.

[0037] Specifically, the first mounting plate 101 transmits vibration to the top of the first elastic member 202. The first elastic member 202 absorbs vibration energy through the deformation of its elastic material and converts the vibration energy into elastic potential energy. The first mounting plate 101 is snapped into the first annular groove 201 to ensure that the vibration can be smoothly transmitted to the first elastic member 202 and further attenuate the vibration through elastic deformation. The first support rod 203 provides structural support.

[0038] In this embodiment, a first elastic element 202 (such as rubber or a spring) is sleeved on the first support rod 203, providing elastic support. When the compressor generates axial vibration, the first elastic element 202 absorbs vibration energy through its elastic deformation, converting the vibration energy into elastic potential energy, thereby reducing the propagation of vibration. Through the deformation of the elastic element, the vibration energy is effectively absorbed, reducing the vibration intensity transmitted to the air conditioner base plate 5 or other components. This arrangement significantly improves vibration reduction efficiency. The first elastic element 202 and the first support rod 203 are coaxially and vertically arranged. This arrangement ensures that vibration can be transmitted along a predetermined path, reducing the coupling of vibration in different directions. This structural stability can effectively prevent the vibration damping component from shifting or deforming during operation. The first support rod 203 provides structural support, ensuring that the first elastic element 202 remains stable during vibration and will not fail due to excessive deformation. This arrangement improves the service life and reliability of the vibration damping component.

[0039] See also Figures 1 to 4 As shown, one end of the first support rod 203 is connected to the base plate 5, and the other end of the first support rod 203 extends out of the first elastic member 202 and is fitted with a locking member 204. Since the first elastic member 202 is engaged with the first mounting plate 101, the other end of the first support rod 203 extends out of the first mounting plate 101. The locking member 204 is used to axially limit the first elastic member 202. The first elastic member 202 has through holes that pass through both ends. The end of the first support rod 203 that extends out of the first elastic member 202 is machined with a threaded section, while the section of the first support rod 203 that is fitted with the first elastic member 202 is a smooth rod. A stepped structure is formed between the threaded section and the smooth rod. The locking member 204 is a nut.

[0040] Specifically, align the through hole of the first elastic element 202 with the smooth section of the first support rod 203, and insert the first elastic element 202 onto the first support rod 203 until the bottom end of the first elastic element 202 contacts the base plate 5. Ensure that the first mounting through hole 111 of the first mounting plate 101 is aligned with the first annular groove 201 of the first elastic element 202. Insert the first mounting plate 101 onto the first elastic element 202 from above until the first mounting plate 101 is engaged in the first annular groove 201, ensuring that the first mounting plate 101 is firmly engaged in the first annular groove 201 and that there is tight contact between the mounting plate and the elastic element. Align the locking element 204 (nut) with the threaded section of the first support rod 203 and screw the nut in until the nut abuts against the stepped structure.

[0041] In this embodiment, the first elastic member 202 is sleeved onto the first support rod 203 until its bottom end contacts the bottom plate 5, which ensures that the first elastic member 202 has a stable support point in the axial direction, preventing axial displacement during operation. By clamping the first mounting plate 101 into the first annular groove 201 of the first elastic member 202, the tight connection between the first mounting plate 101 and the first elastic member 202 is ensured. This clamping mode not only provides a stable mechanical connection, but also ensures that vibration can be smoothly transmitted to the first elastic member 202 and absorbed thereby. The first mounting plate 101 is clamped in the first annular groove 201, and this clamping mode provides a stable mechanical connection, ensuring that the vibration damping member will not loosen or fall off during operation. By screwing in the nut until the nut abuts against the step structure, the position of the first elastic member 202 is further fixed. This arrangement not only prevents the displacement of the first elastic member 202 in the axial direction, but also ensures the stability of the entire vibration damping structure.

[0042] As a specific embodiment, there is a radial unilateral gap x between the first annular groove 201 of the first vibration damping member 2 and the first support rod 203 (assuming the circumferential gap is uniform at this time), where 1 mm < x < 10 mm. If the maximum tangential displacement of the outer wall of the compressor housing is x1 when the conventional vibration damping gasket solution for a compressor is adopted, then setting x = x1 ± 0.5 is acceptable.

[0043] With reference to Figures 1 to 6 , the vibration damping structure further comprises a support leg 6, the support leg 6 comprises a first support plate 601 and a second support plate 602, the first support plate 601 is horizontally arranged, the first support plate 601 is arranged opposite to the first mounting plate 101 with a certain distance reserved therebetween, the first mounting plate 101 is arranged above the first support plate 601, one end of the first vibration damping member 2 is connected to the first mounting plate 101, and the other end of the first vibration damping member 2 is connected to the first support plate 601, that is, the top of the first elastic member 202 is clamped to the first mounting plate 101, the first support plate 601 is mounted on the bottom plate 5, the bottom end of the first support rod 203 is connected to the first support plate 601, the side wall of the first support member facing the vibrating member 4 is arc-shaped, after the first support plate 601 is mounted on the bottom plate 5, the first support plate 601 is attached to the outer wall of the compressor; the second support plate 602 is vertically arranged, the second mounting plate 102 is arranged opposite to the second support plate 602 with a certain distance reserved therebetween, one end of the second vibration damping member 3 is connected to the second mounting plate 102, and the other end of the second vibration damping member 3 is connected to the second support plate 602.

[0044] In this embodiment, a certain distance is reserved between the first support plate 601 and the first mounting plate 101. One end of the first damping member 2 is connected to the first mounting plate 101, and the other end is connected to the first support plate 601. This arrangement ensures that vibration can be smoothly transmitted to the first damping member 2, and the vibration energy is absorbed by the elastic deformation of the first elastic member 202. Through the supporting effect of the first support plate 601, the vibration energy is effectively absorbed during transmission, reducing the vibration intensity transmitted to the air conditioning base plate 5 or other components. The second support plate 602 has the same function. The first support plate 601 and the second support plate 602 can disperse the stress transmitted by vibration to a larger area, reduce local stress concentration, and thus reduce the risk of fatigue fracture caused by stress concentration. By effectively absorbing tangential vibration, the intensity of vibration transmitted to the connecting pipe is reduced, thereby reducing the risk of fatigue fracture of the connecting pipe. The mounting leg 1 and the supporting leg 6 together define the vibration transmission path, so that axial vibration and tangential vibration can be absorbed and attenuated by the first damping element 2 and the second damping element 3 respectively. This clear path setting reduces the coupling of vibration in different directions and improves the vibration reduction efficiency.

[0045] See also Figures 1 to 6 As shown, the second damping component 3 includes a second elastic element 302 and a second support rod 303. The second elastic element 302 is suspended on the first support plate 601. One end of the second elastic element 302 is connected to the second mounting plate 102, that is, the outer peripheral wall of the second elastic element 302 is provided with a second annular groove 301. The second elastic element 302 is engaged with the second mounting plate 102, and the other end of the second elastic element 302 is connected to the second support plate 602. The tail of the second support rod 303 passes through the second support plate 602 and is connected to the second elastic element 302. The head of the second support rod 303 is fastened to the second support plate 602. The second support rod 303 is a bolt. The second support plate 602 is arranged horizontally. The second elastic element 302 is made of rubber or is a spring.

[0046] Specifically, the second mounting plate 102 transmits vibration to one end (left end) of the second elastic element 302. The second elastic element 302 absorbs vibration energy through the deformation of its elastic material, converting the vibration energy into elastic potential energy. The second support rod 303 (bolt) provides structural support, ensuring that the second elastic element 302 remains stable during vibration. Through the elastic deformation of the second elastic element 302, vibration energy is effectively absorbed, reducing the vibration intensity transmitted to the connecting pipes and air conditioning panel. The snap-fit ​​method between the second annular groove 301 and the second mounting plate 102 provides a stable mechanical connection, ensuring that the vibration damping component will not loosen or fall off during operation. The second support rod 303 (bolt) provides structural support, ensuring that the second elastic element 302 remains stable during vibration and will not fail due to excessive deformation. By effectively absorbing tangential vibration, the second elastic element 302 can reduce the intensity of vibration transmitted to the connecting pipes and air conditioning panel, thereby reducing the generation of low-frequency noise. By reducing vibration transmission, the second elastic element 302 can optimize the noise spectrum, reduce noise peaks at specific frequencies, and further reduce noise levels. The elastic deformation of the second elastic element 302 can disperse the stress transmitted by vibration over a larger area, rather than concentrating it in a local area. This stress dispersion can reduce local stress concentration, thereby reducing the risk of fatigue fracture caused by stress concentration.

[0047] In one specific implementation, the axial support stiffness K of the two elastic elements are related. Let the stiffness of the first elastic element 202 be K1 and the stiffness of the second elastic element 302 be K2, then K2 <K1*0.75。

[0048] See also Figures 1 to 6 As shown, multiple mounting feet 1 are provided along the circumferential outer wall of the vibrating element 4, and each mounting foot 1 is provided with a vibration damping component.

[0049] In this embodiment, three mounting feet 1 are provided, evenly distributed at 120° intervals around the compressor housing. By setting multiple mounting feet 1 on the circumferential outer wall of the vibrating component 4, each foot is equipped with a vibration damping component, multi-point support and vibration damping can be achieved. This multi-point vibration damping method can more comprehensively absorb and attenuate vibration energy, reducing the intensity of vibration transmitted to the air conditioner base plate 5 and other components. The multiple vibration damping components are evenly distributed circumferentially, which can absorb vibration energy more evenly and avoid vibration concentration caused by single-point vibration damping. This uniform distribution can significantly improve vibration damping efficiency and reduce the overall impact of vibration on the system. Multiple mounting feet 1 provide multiple support points, enhancing the structural stability of the entire vibration damping system. This multi-point support method can effectively prevent the vibration damping component from lateral displacement or tilting during operation, ensuring the stable operation of the vibration damping system. Through multi-point support, vibration energy is distributed to multiple vibration damping components, reducing the stress borne by a single vibration damping component. This arrangement can effectively reduce structural deformation caused by vibration and improve the rigidity of the entire system. Multiple vibration damping components are evenly distributed circumferentially, which can absorb vibration energy more evenly and reduce the coupling of vibration in different directions. This uniform distribution can significantly improve the vibration damping effect and reduce the overall impact of vibration on the system. Through multi-point vibration damping, vibration energy is distributed to multiple vibration damping components, reducing local stress concentration. This setting can effectively reduce the risk of fatigue fracture caused by stress concentration and improve the reliability of the system.

[0050] In one specific implementation, the second damping component 3 of the two damping components is located on the right side of the first damping component 2, and the second damping component of the other damping component is located on the left side of the first damping component 2. This method allows for flexible adjustment of the installation position of the second damping component 3 according to the different transmission directions and magnitudes of the vibration source.

[0051] A compressor includes a vibration damping structure, which is the vibration damping structure described above. The vibrating component 4 is the compressor. The mounting feet 1 are set on the bottom side wall of the compressor. After adopting the above vibration damping structure, a single-cylinder compressor can be used to replace the double-cylinder compressor to achieve a similar vibration level, thereby reducing costs and effectively solving the problem of large start-stop impact vibration of vertical air conditioner compressors.
