[0002] When the air conditioner is started and running, the compressor is used as a power component. Because the frequency of the compressor has not risen temporarily, the compressor is in an unsteady state. Directional vibration, the vibration mode diagram is as follows Figure 1-Figure 2 As shown, due to the large vibration, vibration noise will be generated. The vibration generated by the compressor will be transmitted to the bottom plate shell through the installation pad, which will cause the vibration of the wall or radiate it as a noise source, resulting in a bad user experience. Especially for inverter air conditioners, the torque of the compressor is relatively large, and the vibration is even greater during operation.
At present, in order to reduce the vibration of the compressor, compressor foot pads are generally arranged under the compressor footing, and the compressor foot pads are sleeved on the compressor positioning bolts during installation. However, the existing compressor foot pads, the upper and lower sides of the foot pads The two ends fit together with the positioning bolts, and the contact area between the two is large. Under the continuous vibration of the compressor, it will cause the compressor foot pad and the positioning bolts to collide with each other, and there will be a chug sound in some frequency bands, which affects the user. experience

Embodiment Construction
[0031]In order to better understand the technical solution of the present invention, the present invention will be further described below in connection with the examples and drawings, but embodiments of the present invention are not limited thereto.
[0032]SeeFigure 3 - Figure 4 This example discloses a foot pad mechanism of a shock absorbing noise, including foot pad 1 and a positioning bolt 2, wherein the positioning bolt 2 is provided with a stepped structure at a position mating with the foot pad 1, said The step structure includes a first step portion 2-1 at the upper portion and a second step portion 2-2 located at the lower portion, the diameter of the first step portion 2-1, which is smaller than the diameter of the second step portion 2-2. According to the above configuration, on the one hand, since the amplitude of the upper end of the positioning bolt 2 is large, the main portion of the foot pad 1 and the positioning bolt 2 collision occurred at the upper end of the foot p...

The invention discloses a shock absorption and noise reduction foot pad mechanism, a compressor and an air conditioner. The foot pad mechanism comprises a foot pad and a positioning bolt, and a step structure is arranged at the position, matched with the foot pad, of the positioning bolt. The foot pad mechanism not only can play a shock absorption role on a compressor, but also can reduce noise generated when the foot pad of the compressor collides with the positioning bolt, so that the user experience is improved.
Description
Technical field[0001]The present invention relates to the field of air conditioning, and more particularly to a foot pad mechanism, a compressor, and an air conditioner for shock absorption noise reduction.Background technique[0002]When the air conditioner is started and run, the compressor acts as a power component because the compressor frequency is temporarily not rising. When the compressor is in a non-stable state, the compressor torque is large, so that the compressor is different from Directional vibration, vibration modeFigure 1 - Figure 2 As shown, since the vibration is large, vibration noise is generated, and the vibration generated by the compressor is transmitted on the bottom plate housing by the mounting foot pad, resulting in vibration of the wall or as a noise source radiation, resulting in a bad user experience. Especially inverter air conditioners, the torque of the compressor is large, and the vibration is greater. At present, in order to reduce the vibration of ...
