Description

Technical Field

[0001] This utility model relates to the field of vibration damping device technology, and in particular to a vibration damping suspension base. Background Technology

[0002] A vibration damping base is a device used to reduce vibration and noise generated during the operation of an air conditioning compressor. It is typically installed between the compressor and the support surface. Chinese patent document CN212318245U discloses an industrial air conditioning compressor vibration damping base. This vibration damping base achieves structural vibration damping through a base plate at the bottom of the base body and reinforcing ribs between the base plate and the base body, physical vibration damping through anti-vibration pads, and noise reduction through sound-absorbing cotton.

[0003] However, in the aforementioned industrial air conditioning compressor vibration damping base, the sound-absorbing cotton is placed around the base body and is easily affected by external environmental factors, such as dust and humid air, which can lead to a decrease in the sound absorption performance of the sound-absorbing cotton.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] The present invention provides a vibration-damping suspension base, which aims to solve the problem that the sound-absorbing cotton of the existing industrial air conditioner compressor vibration-damping base is placed around the base body and is easily affected by external environmental factors, which will lead to a decrease in the sound absorption performance of the sound-absorbing cotton.

[0006] To achieve the above objectives, the solution provided by this utility model is as follows:

[0007] A vibration-damping suspension base includes a base body; the base body has a cavity, and a first rubber damping layer and a sound-absorbing cotton layer are arranged sequentially from top to bottom in the cavity.

[0008] Optionally, the base body includes a top shell and a detachable bottom plate disposed at the bottom of the top shell; a second rubber damping layer is also provided between the bottom of the top shell and the bottom plate.

[0009] Optionally, two sets of damping shock absorbers are provided on both sides of the bottom of the base plate.

[0010] Optionally, the base plate extends outward toward the top shell and is provided with a first mounting part; the damping shock absorber is connected to the first mounting part by bolts.

[0011] Optionally, a second mounting portion is connected to the bottom outer side of the top shell, the second mounting portion corresponding to the first mounting portion; the two sides of the second rubber damping layer are clamped between the second mounting portion and the first mounting portion, and both the second rubber damping layer and the second mounting portion are provided with mounting holes for bolts to pass through; a nut for tightening the second mounting portion is fitted on the bolt.

[0012] Optionally, the thickness ratio of the first rubber damping layer to the sound-absorbing cotton layer is 1:(8-9).

[0013] Optionally, the sound-absorbing cotton layer is at least one of polyester fiber sound-absorbing cotton layer, glass fiber sound-absorbing cotton layer, and polyurethane foam sound-absorbing cotton layer.

[0014] Optionally, both the first rubber damping layer and the second rubber damping layer are butyl rubber damping layers.

[0015] Beneficial effects:

[0016] This invention provides a vibration-damping suspension base. By creating a cavity within the base body and filling the cavity with sound-absorbing cotton to form a sound-absorbing cotton layer, compared to placing sound-absorbing cotton around the base body, the sound-absorbing cotton filling the cavity is unaffected by external dust and humid air, allowing it to maintain excellent sound absorption performance for a long time. Furthermore, by placing a first rubber damping layer above the sound-absorbing cotton layer within the cavity, the first rubber layer absorbs vibrations generated by the air conditioner compressor during operation. Combined with the sound-absorbing cotton layer absorbing noise penetrating downwards into the base body and blocking noise from escaping through the suspension base, the vibration-damping effect of the suspension base is significantly improved.

[0026] Please see Figure 1 and Figure 2 This invention provides a vibration-damping suspension base, comprising a base body 1. The base body 1 has a cavity, within which a first rubber damping layer 2 and a sound-absorbing cotton layer 3 are sequentially arranged from top to bottom. By creating a cavity within the base body 1 and filling it with sound-absorbing cotton to form the sound-absorbing cotton layer 3, this invention, compared to placing sound-absorbing cotton around the perimeter of the base body 1, ensures that the sound-absorbing cotton is not affected by external dust or humid air when filling the cavity, allowing it to maintain excellent sound absorption performance for a longer period. Furthermore, by placing the first rubber damping layer 2 above the sound-absorbing cotton layer 3 within the cavity, the first rubber layer absorbs vibrations generated by the air conditioner compressor during operation. Combined with the sound-absorbing cotton layer 3, this absorbs noise penetrating downwards into the base body 1 and blocks noise from exiting the suspension base, thereby significantly improving the vibration-damping effect of the suspension base.

[0027] Furthermore, by setting a cavity in the base body 1, this utility model can induce resonance of the air column inside the cavity when low-frequency noise enters the cavity, causing sound energy to be converted into heat energy and consumed. Combined with the sound-absorbing cotton inside the cavity, it can doubly weaken low-frequency noise, better cope with the low-frequency noise generated by the air compressor, and reduce its impact on the surrounding environment.

[0028] Of course, sound-absorbing cotton can be retained on the surface of the base body 1, and at the same time, the use of sound-absorbing cotton in the cavity can make the vibration reduction and noise reduction effect of the vibration-damping suspension base reach the optimal level.

[0029] Specifically, the first rubber damping layer 2 and the sound-absorbing cotton layer 3 can be bonded together with strong adhesive.

[0030] Optionally, the base body 1 includes a top shell 11 and a detachable bottom plate 12 disposed at the bottom of the top shell 11; a second rubber damping layer 4 is also provided between the bottom of the top shell 11 and the bottom plate 12. Since the top shell 11 and the bottom plate 12 are usually connected and fixed by bolts 6 (i.e., a rigid connection), in order to prevent the vibration generated by the air conditioner compressor from being transmitted to the vibration-damping suspension base and causing the fixing bolts 6 to loosen and generate vibration and noise, this utility model provides a second rubber damping layer 4 between the bottom of the top shell 11 and the bottom plate 12. The second rubber damping layer 4 is used to absorb the vibration transmitted to the bottom plate 12, making it less likely for the fixing bolts 6 to loosen. While ensuring a firm connection between the top shell 11 and the bottom plate 12, it can also further improve the vibration reduction and noise reduction effect.

[0031] Optionally, two sets of damping vibration dampers 5 are provided on both sides of the bottom of the base plate 12. The damping vibration dampers 5 can provide additional buffering and weakening for the vibration generated by equipment such as air conditioning compressors on the base body 1, thereby significantly reducing the vibration transmitted to the support surface (such as the ground), thus improving the vibration reduction performance of the entire suspended base.

[0032] Optionally, the two sets of damping vibration dampers 5 should be symmetrically arranged on both sides of the bottom of the base plate 12. This allows the damping vibration dampers 5 to evenly bear and disperse the vibrations generated by equipment such as air conditioning compressors. While improving the vibration damping performance of the entire suspended base, it can also extend the service life of the damping vibration dampers 5 and make the base body 1 bear the force evenly, so that equipment such as air conditioning compressors can be stably installed on the base body 1.

[0033] In an optional embodiment, in order to install the damping shock absorber 5, the base plate 12 extends outward toward the top shell 11 and is provided with a first mounting part 111; the damping shock absorber 5 is located below the first mounting part 111, and the damping shock absorber is connected to the first mounting part 111 by bolts 6, thereby ensuring the structural stability and vibration reduction performance of the entire vibration-damping suspension base.

[0034] Optionally, a second mounting part 121 is connected to the outer bottom of the top shell 11, and the second mounting part 121 corresponds to the first mounting part 111; the two sides of the second rubber damping layer 4 are clamped between the second mounting part 121 and the first mounting part 111, and both the second rubber damping layer 4 and the second mounting part 121 are provided with mounting holes for the bolts 6 to pass through; the bolts 6 are fitted with nuts 7 for pressing the second mounting part 121. Therefore, the second rubber damping layer 4 can be firmly clamped between the top shell 11 and the bottom plate 12 of the base body 1, so that the second rubber damping layer 4 can continue to play a role in the vibration reduction process, thereby avoiding the loosening of the fixing bolts 6 due to the hard connection between the top shell 11 and the bottom plate 12, which would generate additional noise, ensure that the top shell 11 and the bottom plate 12 are firmly connected, and enhance the structural stability of the vibration reduction suspension base.

[0035] Optionally, the thickness ratio of the first rubber damping layer 2 to the sound-absorbing cotton layer 3 is 1:(8-9). Specifically, the first rubber damping layer 2 is mainly responsible for absorbing the vibration generated by the air conditioner compressor, while the sound-absorbing cotton layer 3 can also assist in vibration reduction while absorbing noise. A thinner first rubber damping layer 2 can save material costs while meeting basic vibration reduction requirements. A thicker sound-absorbing cotton layer 3 can further buffer the vibrations that are not fully absorbed by the first rubber damping layer 2, enhancing the overall vibration reduction effect and making the weakening effect of the suspended vibration damping base on the compressor vibration more significant. Moreover, when the thickness ratio of the first rubber damping layer 2 to the sound-absorbing cotton layer 3 is controlled within the above range, the sound-absorbing cotton layer 3 can fully exert its sound absorption advantages. The porous structure inside the sound-absorbing cotton layer 3 can more effectively convert sound energy into heat energy for consumption, thereby efficiently absorbing and blocking noise, reducing noise penetration into the base, and reducing the impact on the surrounding environment.

[0036] Optionally, the sound-absorbing cotton layer 3 can be at least one of polyester fiber sound-absorbing cotton layer 3, glass fiber sound-absorbing cotton layer 3, and polyurethane foam sound-absorbing cotton layer 3. More preferably, the sound-absorbing cotton layer 3 is a polyester fiber sound-absorbing cotton layer 3. The internal structure of polyester fiber material is regular and uniform, which can stably absorb low-frequency noise. Moreover, polyester fiber material is environmentally friendly and safe, and will not release harmful substances during use.

[0037] Optionally, both the first rubber damping layer 2 and the second rubber damping layer 4 are butyl rubber damping layers. Butyl rubber buffers the impact force of vibration through its own elastic deformation, stores the vibration energy, and then slowly releases it, thereby reducing the vibration amplitude.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
