According to the vibration damping pad 1 of the embodiment of the utility model, since the projection of at least part of the supporting sheet 12 is positioned in the supporting surface 1121, the supporting surface 1121 can be supported in an auxiliary way through the supporting sheet 12, so that the structural stability and the bearing capacity of the vibration damping pad 1 are improved, the supporting portion 112 surrounds the periphery of the connecting portion 111, the contact area between the vibration damping body 11 and the chassis 3 and the compressor can be increased, the vibration damping effect of the vibration damping body 11 is not affected due to the fact that the supporting sheet 12 is arranged in the supporting portion 112, the deformation of the supporting portion 112 is reduced, and the integral rigidity of the vibration damping pad 1 is increased. Therefore, the vibration damping pad 1 of the embodiment of the present utility model has high stability and good vibration resistance.

It will be appreciated that since the damping body 11 has elasticity, so that the damping pad 1 has good damping performance, the support sheet 12 can provide additional rigidity, and the support sheet 12 is hidden in the damping body 11, i.e. the support sheet 12 is not directly contacted with the compressor or chassis 3, so that the damping effect of the damping body 11 is not affected.

In addition, the supporting portion 112 surrounds the outer periphery of the connecting portion 111, so that the radial width of the supporting portion 112 is larger than that of the connecting portion 111, and therefore the contact area between the vibration damping body 11 and the compressor can be increased, and the three-way exciting force of the compressor is further attenuated in a matched mode.
