In an embodiment of the present invention, as shown in fig. 4 to 8, the vibration damping plate 100 includes:
a first substrate 10;
a second substrate 20, the second substrate 20 and the first substrate 10 being stacked, a first damping gap being formed between the second substrate 20 and the first substrate 10; and
a first damping damper 30 filled in the first damping gap.
When the vibration is transmitted to the vibration damping plate 100, the first vibration damping 30 is deformed (elastically sheared) due to the vibration, thereby generating structural damping and losing vibration energy to effectively perform the vibration damping and noise reduction functions.
When the vibration damping plate 100 is applied to an air conditioner, such as an outdoor unit of an air conditioner, as shown in fig. 1, the vibration damping plate 100 may be a bottom plate 200, a surrounding plate 300, a valve plate 100, a top cover, or the like of the outdoor unit of the air conditioner; alternatively, the chassis 200 and/or the valve plate 100 may adopt the above vibration damping plate 100 structure since the chassis 200 and the valve plate 100 are closer to the compressor.
When the vibration damping plate 100 is applied to a refrigerator, the vibration damping plate 100 may be a bottom chassis 200 of the refrigerator, or the like.
In this way, by providing the first vibration damping damper 30 in the vibration damping plate 100, on the one hand, the forced vibration of the vibration damping plate 100 of the compressor can be reduced, and on the other hand, the vibration amplitude at the natural frequency of the vibration damping plate 100 can be reduced due to the damping characteristic of the first vibration damping damper 30, so that the resonance phenomenon can be reduced or eliminated, and thus the noise when the outdoor unit of the air conditioner or the refrigerator is operated can be (effectively) reduced.
In a specific embodiment, the first vibration damping device 30 may be made of an elastic material, such as rubber, asphalt, or silica gel, so as to have a good damping effect.

In order to better embody the vibration damping effect of the vibration damping plate 100, the utility model discloses still provide the material parameter of sheet metal component and damping layer 30, specifically see the following table.
In one embodiment, the thickness of the damping plate 100 may be greater than or equal to 0.8 mm and less than or equal to 2 mm, such as 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 1.95 mm. Thus, the damping plate 100 can have sufficient structural strength, and the excessive thickness of the damping plate 100 can be avoided, thereby reducing the cost.
In a specific embodiment, the damping plate can be manufactured by stamping.
In the exemplary embodiment, the first damping gap and the first damping damper 30 have many configurations, which will be exemplified below.
In the first embodiment of the vibration damping plate 100 of the present invention, as shown in fig. 4, the first damping gap is a layered gap, and the first damping layer 30 is formed as the damping layer 30. In this way, when the vibration is transmitted to the vibration damping plate 100, the damping layer 30 generates shear deformation due to the relative displacement between the two surfaces during the vibration, so as to generate structural damping to lose the vibration energy, thereby effectively performing the vibration damping and noise reduction functions. Moreover, the layered damping structure is convenient to produce and process, and the damping area is large.
Specifically, as shown in fig. 4, the first substrate 10, the damping layer 30 and the second substrate 20 form a sandwich structure.
Further, as shown in fig. 4, the damping layer 30 has a flat plate shape so that the damping layer 30 has a simple structure.

Of course, in other embodiments, the first damping gap may be a non-laminar gap.
As in the sixth embodiment of the vibration damping plate 100 of the present invention, as shown in fig. 9 and 10, the first vibration damping gaps are distributed at intervals, and each of the first vibration damping gaps is filled with the first vibration damping 30. In this way, the vibration damping plate 100 can have a good vibration damping effect by multi-stage vibration damping of the first vibration damping dampers 30 in the plurality of first vibration damping gaps.

Wherein the plurality of first damping gaps may be concentrically distributed. Optionally, the first damping gap is annular or square annular.
In the eighth embodiment of the vibration damping plate 100 of the present invention, the main difference from the sixth embodiment of the vibration damping plate 100 of the present invention is that, as shown in fig. 12, the first vibration damping gap is formed in a closed hole shape. Wherein the plurality of first damping gaps may be uniformly distributed within the damping plate 100.
Of course, it should be noted that in particular embodiments, the damping plate 100 may be provided in a more layered configuration.
