In some embodiments, as shown in FIG. 6, the plurality of damping protrusions 14 have the same protrusion height.
In the present application, the default protrusion height is the protrusion height of the vibration-damping protrusion 14 in an uncompressed state, i.e., a natural state. In this embodiment, the plurality of vibration reduction protrusions 14 are arranged to have the same protrusion height, so that the plurality of vibration reduction protrusions 14 can contact the member to be vibration reduced at the same time, and the support stability of the vibration reduction pad 10 is improved.

And under the condition that the compressor amplitude is larger or smaller impact load is generated, one or more types of vibration reduction bulges with higher bulge height are pressed and deformed, the height of the next type of vibration reduction bulge with the bulge height is reached, at the moment, the next type of vibration reduction bulge with the bulge height is also contacted with the compressor, the compressor is supported by the multiple types of vibration reduction bulges, the area of a supporting surface of the vibration reduction pad 10 for the compressor is increased, the vibration reduction pad 10 is positioned in a high-rigidity area, the vibration of the compressor can be quickly attenuated by utilizing the constraint effect of high rigidity, the overall shaking amplitude of the compressor is effectively reduced, thereby protecting connecting pipelines inside and outside the compressor, and preventing the pipelines from generating phenomena such as pipe breakage and the like under the impact load.
In some embodiments, as shown in fig. 3 to 5, the plurality of vibration damping protrusions 14 includes a first type of vibration damping protrusion 14a and a second type of vibration damping protrusion 14b, the first type of vibration damping protrusion 14a having a protrusion height greater than that of the second type of vibration damping protrusion 14 b; the first type of vibration reduction protrusion 14a is used for preferentially contacting with a member to be subjected to vibration reduction, and the second type of vibration reduction protrusion 14b is used for contacting with the member to be subjected to vibration reduction under the condition that the first type of vibration reduction protrusion 14a is deformed to the height of the second type of vibration reduction protrusion 14b under stress.

It is also possible to set different types of the vibration damping protrusions to have different rigidities, and it is assumed that the rigidities of the vibration damping protrusions 14 in the same type of the vibration damping protrusions are the same in the case where the number of the vibration damping protrusions 14 in the same type of the vibration damping protrusions is at least two.
