To domestic air conditioner, for example air condensing units, generally through installing support 220 fixed mounting on the wall body, adopt the utility model discloses a damping callus on the sole 100, can avoid the vibration of compressor to transmit to installing support 220 effectively on, avoided installing support 220 to take place resonance. To on-vehicle air conditioner, generally fix on the frame through installing support 220, adopt the utility model discloses a vibration damping callus on sole 100 can avoid on the one hand the vibration of compressor to transmit on installing support 220, on the other hand also can avoid the vehicle to transmit on the footing 210 of air conditioner 300 in the vibration of driving in-process frame, and then causes the damage to the inner structure of air conditioner 300 (for example compressor etc.), promptly, this vibration damping callus on sole 100 has two-way vibration isolation effect.

It is worth mentioning that, when the compressor of the air conditioner 300 has high frequency or high rotation speed, the damping foot pad 100 of the present invention still has a better vibration isolation effect. This is because the vibration amplitude of the compressor is large when the compressor is at a high frequency or a high rotation speed, and if the conventional vibration-damping foot pad is used, the vibration amplitude transmitted to the mounting bracket 220 is also large, and the resonance point of the mounting bracket 220 is usually located in a high frequency region, which easily causes the mounting bracket 220 to resonate, thereby generating a large vibration noise. And adopt the utility model discloses a damping callus on sole 100, because the utility model discloses a damping callus on sole 100 has better vibration isolation effect, makes the vibration range that makes to transmit installing support 220 less to the resonance of installing support 220 has been improved more effectively, the noise of vibration has been greatly reduced.

In addition, please refer to fig. 12 and 13, compare the new damping foot pad 100 (the damping foot pad 100 of the present invention) with the original damping foot pad 100 (the conventional damping foot pad 100), after the damping foot pad 100 of the present invention is adopted, the vibration amplitude of the mounting bracket 220 is reduced to 1/3, the peak value of the low frequency buzzing sound caused by the wall body is reduced by 11dB (e.g. reduced from 41dB to 30dB in fig. 13), and the vibration and hearing is improved obviously.

The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
