[0026] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] Example 1

[0028] like Figure 1 As shown, this embodiment provides a vibration damping device, including a vibration damping assembly 1, wherein the vibration damping assembly 1 includes a first vibration damping structure 2, a second vibration damping structure 3 is arranged below the first vibration damping structure 2, and the first vibration damping structure 2 and the second vibration damping structure 3 have the same or different elastic stiffness; the bottom of the first vibration damping structure 2 is connected to the top of the second vibration damping structure 3, and the first vibration damping structure 2 is combined with the second vibration damping structure 3 to adjust the vibration damping performance and height.

[0029] The first vibration damping structure 2 and the second vibration damping structure 3 have the same shape and height, but the first vibration damping structure 2 and the second vibration damping structure 3 are made of different materials and have different elastic stiffnesses.

[0030] like Figure 4 As shown, the first vibration damping structure 2 and the second vibration damping structure 3 are both modular structures, and the first vibration damping structure 2 and the second vibration damping structure 3 are combined to replace the original integrated vibration damping structure. According to the height and vibration damping performance requirements, other vibration damping structures such as the first vibration damping structure 2, the second vibration damping structure 3 and / or the third vibration damping structure 8 can be added, and the added vibration damping structure can be located above the first vibration damping structure 2, below the second vibration damping structure 3 and / or between the first vibration damping structure 2 and the second vibration damping structure 3.

[0031] The damping device is provided with a first damping structure 2 and a second damping structure 3 from top to bottom, and the first damping structure 2 is convex downward on both sides of a side close to the second damping structure 3, and concave upward in the middle. The second damping structure 3 is concave downward on both sides of a side close to the first damping structure 2, and convex upward in the middle, so that the bottom of the first damping structure 2 and the top of the second damping structure 3 are adapted, thereby assembling the first damping structure 2 and the second damping structure 3 together.

[0032] The first vibration damping structure 2 and the second vibration damping structure 3 can exchange positions, that is, the vibration damping device is provided with the second vibration damping structure 3 and the first vibration damping structure 2 from top to bottom, and by changing the number and positions of different vibration damping structures, vibration damping devices with different heights and vibration damping performances can be combined.

[0033] The present embodiment provides a vibration reduction device, including a vibration reduction assembly 1, the vibration reduction assembly 1 including a first vibration reduction structure 2, a second vibration reduction structure 3 is arranged below the first vibration reduction structure 2, the first vibration reduction structure 2 and the second vibration reduction structure 3 have the same or different elastic stiffness; the bottom of the first vibration reduction structure 2 is connected to the top of the second vibration reduction structure 3, and the first vibration reduction structure 2 is combined with the second vibration reduction structure 3 to adjust the vibration reduction performance and height. The first vibration reduction structure 2 and the second vibration reduction structure 3 are modular, and different vibration reduction structures are selected for combination according to different height requirements. Only the modular first vibration reduction structure 2 or the second vibration reduction structure 3 needs to be produced, thereby reducing production costs and the difficulty of material distribution and process management. The first vibration reduction structure 2 is connected to the second vibration reduction structure 3, and other vibration reduction structures can be added between the first vibration reduction structure 2 and the second vibration reduction structure 3 according to the compressor model and vibration reduction requirements to adjust the height of the vibration reduction device. By combining multiple vibration reduction structures to meet different height requirements, it has universality. In addition, different vibration damping structure combinations can achieve different elastic stiffnesses, and the number of the first vibration damping structure 2 and the second vibration damping structure 3 can be adjusted, and the positions of the first vibration damping structure 2 and the second vibration damping structure 3 can be exchanged, so as to meet different vibration damping effects.

[0034] Example 2

[0035] like Figure 1 As shown, this embodiment provides a vibration damping device, including a vibration damping assembly 1, wherein the vibration damping assembly 1 includes a first vibration damping structure 2, a second vibration damping structure 3 is arranged below the first vibration damping structure 2, and the first vibration damping structure 2 and the second vibration damping structure 3 have the same or different elastic stiffness; the bottom of the first vibration damping structure 2 is connected to the top of the second vibration damping structure 3, and the first vibration damping structure 2 is combined with the second vibration damping structure 3 to adjust the vibration damping performance and height.

[0036] The vibration reduction device further comprises a fixing assembly 4 , which is connected to the vibration reduction assembly 1 , and is used to fix the vibration reduction assembly 1 .

[0037] like Figure 4 As shown, the fixing assembly 4 includes a compressor support frame 5 , and the compressor support frame 5 is clearance-matched with the first vibration-damping structure 2 .

[0038] like Figure 2As shown, the fixing assembly 4 further includes a base 6 , on which a positioning nut 7 is provided. The base 6 is connected to the positioning nut 7 , and the positioning nut 7 is used to position the vibration reduction assembly 1 .

[0039] The first vibration reduction structure 2 and the second vibration reduction structure 3 are both vibration reduction pads, which have the same or different elastic stiffness and are modular structures with the same height and shape. The vibration reduction pads are generally made of rubber and are made in an integrated manner.

[0040] An inner hole is provided on the compressor support frame 5, and there is a clearance fit between the neck of the first vibration damping structure 2 and the inner hole. The first vibration damping structure 2 can be directly assembled into place without having to press the first vibration damping structure 2 in with great force, thereby reducing assembly resistance and improving assembly efficiency.

[0041] The base 6 of the present embodiment is an air conditioner bottom plate, and the first vibration reduction structure 2 and the second vibration reduction structure 3 are vibration reduction pads with the same height and shape and the same or different elastic stiffness.

[0042] Figure 8 1 is a schematic diagram of an existing vibration reduction device, in which only a conventional vibration reduction pad 15 is arranged on a base 6, a screw 10 passes through the conventional vibration reduction pad 15, and the top of the screw 10 is fixed with a nut 11. The existing vibration reduction device requires strong squeezing and rotating action to press the head of the conventional vibration reduction pad 15 into the inner hole of the compressor support frame 5, which is inconvenient to assemble.

[0043] When installing the vibration reduction device in this embodiment, the positioning nut 7 is first welded to the bottom plate of the air conditioner, and the positioning nut 7 plays a role in plane positioning of the vibration reduction assembly 1. Then, a vibration reduction pad is placed on the positioning nut 7, and the required number of vibration reduction pads are assembled together according to the elastic stiffness required for vibration reduction, and vibration reduction pads with different elastic stiffness are assembled together through concave-convex fit. After the vibration reduction assembly 1 is assembled on the positioning nut 7, the compressor support frame 5 is placed on the neck support of the first vibration reduction structure 2. Since the neck of the first vibration reduction structure 2 and the inner hole of the compressor support frame 5 are clearance fit, they can be directly installed in place. Therefore, this operation step does not require strong squeezing and tightening, which reduces the assembly resistance and solves the problem that the vibration reduction pad head needs to be rotated and squeezed into the inner hole of the compressor support frame 5 in the existing installation method, which is inconvenient to assemble, thereby greatly improving the assembly efficiency of the vibration reduction pad.

[0044] The vibration damping device described in this embodiment also includes a fixing component 4, which is connected to the vibration damping component 1, and the fixing component 4 is used to fix the vibration damping component 1. The fixing component 4 includes a compressor support frame 5, and the compressor support frame 5 is clearance-matched with the first vibration damping structure 2. The fixing component 4 also includes a base 6, and a positioning nut 7 is provided on the base 6. The base 6 and the positioning nut 7 are connected, and the positioning nut 7 is used to position the vibration damping component 1. When installing the vibration damping device, first weld the positioning nut 7 to the base 6, then install the vibration damping component 1 on the positioning nut 7, and then insert the neck of the first vibration damping structure 2 into the inner hole of the compressor support frame 5. During this installation process, the positioning nut 7 plays a role in planar positioning of the vibration damping component 1, so that the vibration damping component 1 can be installed in the correct position more accurately, greatly improving the accuracy of installation. At the same time, the neck of the first vibration damping component 1 and the inner hole of the compressor support frame 5 are clearance-matched, and can be directly installed in place without using a large force to rotate and squeeze the head of the vibration damping pad into the inner hole of the compressor support frame 5, thereby reducing assembly resistance, solving the problem of difficult assembly of existing vibration damping pads, and improving installation efficiency.

[0045] Example 3

[0046] like Figure 1 As shown, this embodiment provides a vibration damping device, including a vibration damping assembly 1, wherein the vibration damping assembly 1 includes a first vibration damping structure 2, a second vibration damping structure 3 is arranged below the first vibration damping structure 2, and the first vibration damping structure 2 and the second vibration damping structure 3 have the same or different elastic stiffness; the bottom of the first vibration damping structure 2 is connected to the top of the second vibration damping structure 3, and the first vibration damping structure 2 is combined with the second vibration damping structure 3 to adjust the vibration damping performance and height.

[0047] The vibration reduction device further comprises a fixing assembly 4 , which is connected to the vibration reduction assembly 1 , and is used to fix the vibration reduction assembly 1 .

[0048] like Figure 2 As shown, the fixing assembly 4 further includes a base 6 , on which a positioning nut 7 is provided. The base 6 is connected to the positioning nut 7 , and the positioning nut 7 is used to position the vibration reduction assembly 1 .

[0049] like Figure 4 As shown, a third vibration damping structure 8 is arranged below the second vibration damping structure 3, and the third vibration damping structure 8 and the second vibration damping structure 3 have the same or different elastic stiffness, and the third vibration damping structure 8 and the first vibration damping structure 2 have the same or different elastic stiffness, and the first vibration damping structure 2, the second vibration damping structure 3 and the third vibration damping structure 8 have the same height and shape.

[0050] Since the first vibration damping structure 2, the second vibration damping structure 3 and the third vibration damping structure 8 have the same height and shape and are all modular vibration damping pads, the first vibration damping structure 2, the second vibration damping structure 3 and the third vibration damping structure 8 can have the same or different elastic stiffnesses, and vibration damping components 1 with different elastic stiffnesses can be combined according to different elastic stiffness requirements.

[0051] If the elastic stiffness of the first vibration damping structure 2 is HS40, the elastic stiffness of the second vibration damping structure 3 is HS50, and the elastic stiffness of the third vibration damping structure 8 is HS60, then the first combination consists of three vibration damping pads with different elastic stiffnesses, and the elastic stiffness of the first combination is HS40+HS50+HS60=HS150.

[0052] If the elastic stiffness of the first vibration damping structure 2 is HS50, the elastic stiffness of the second vibration damping structure 3 is HS50, and the elastic stiffness of the third vibration damping structure 8 is HS60, that is, the elastic stiffness of the first vibration damping structure 2 and the second vibration damping structure 3 are the same, then the elastic stiffness of the second combination is a combination of two vibration damping pads with the same elastic stiffness and one vibration damping pad with different elastic stiffness, and the elastic stiffness of the second combination is HS50+HS50+HS60=HS160.

[0053] If the elastic stiffness of the first vibration damping structure 2 is HS50, the elastic stiffness of the second vibration damping structure 3 is HS50, and the elastic stiffness of the third vibration damping structure 8 is HS50, that is, the elastic stiffness of the first vibration damping structure 2, the second vibration damping structure 3 and the third vibration damping structure 8 are the same, then the elastic stiffness of the third combination is a combination of three vibration damping pads with the same elastic stiffness, and the elastic stiffness of the third combination is HS50+HS50+HS50=HS150.

[0054] The elastic stiffness of the first combination is HS150, which is less than the elastic stiffness of the second combination, HS160. The elastic stiffness of the first combination is HS150, which is equal to the elastic stiffness of the third combination, HS150. If the required elastic stiffness is HS150, you can choose the first combination or the third combination; if the required elastic stiffness is HS160, you can choose the second combination.

[0055] After the combination to be assembled is determined according to the elastic stiffness requirements, the third vibration damping structure 8 is first placed on the positioning nut 7, and then the second vibration damping structure 3 is assembled on the third vibration damping structure 8 along the height direction, and the first vibration damping structure 2 is assembled on the second vibration damping structure 3 along the height direction. After the first vibration damping structure 2, the second vibration damping structure 3 and the third vibration damping structure 8 are assembled, the first vibration damping structure 2, the second vibration damping structure 3 and the third vibration damping structure 8 are fixed by the fixing assembly 4.

[0056] If a higher vibration damping assembly 1 is required, a fourth vibration damping structure to an Nth vibration damping structure may be further arranged below the third vibration damping structure 8, wherein N>3. The shapes and heights of the fourth vibration damping structure to the Nth vibration damping structure are the same as those of the first vibration damping structure 2. If the height of the first vibration damping structure 2 is h, the height of the first vibration damping structure 2+the second vibration damping structure 3+the third vibration damping structure 8 is 3h, and the height of the first vibration damping structure 2+the second vibration damping structure 3+the third vibration damping structure 8+the fourth vibration damping structure is 4h, thereby meeting different height requirements.

[0057] In this embodiment, a third vibration damping structure 8 is arranged below the second vibration damping structure 3. The third vibration damping structure 8 and the second vibration damping structure 3 have the same or different elastic stiffness, and the third vibration damping structure 8 and the first vibration damping structure 2 have the same or different elastic stiffness. The first vibration damping structure 2, the second vibration damping structure 3 and the third vibration damping structure 8 have the same height and shape. The first vibration damping structure 2, the second vibration damping structure 3 and the third vibration damping structure 8 are all modular vibration damping pads with the same or different elastic stiffness. By combining vibration damping pads with different elastic stiffness together, the vibration damping requirements of different elastic stiffness can be met. During the installation of the vibration damping device, the positioning nut 7 is first welded to the base 6, and then the third vibration damping structure 8 is placed on the positioning nut 7 to complete the plane positioning, and then the second vibration damping structure 3 is assembled on the third vibration damping structure 8 along the height direction, and the first vibration damping structure 2 is assembled on the second vibration damping structure 3, and finally the position of the vibration damping assembly 1 is fixed by the fixing assembly 4 to complete the positioning of the vibration damping assembly 1. Modular vibration damping pads can be used to combine different vibration damping pad combinations according to different elastic stiffness and height requirements. It is only necessary to produce modular vibration damping pads, and there is no need to produce vibration damping pads of different heights, which reduces production costs and alleviates the difficulty of distributing and process management of multiple models of vibration damping pads.
