The compressor 200 has a center of mass, which is commonly understood in the art, i.e., the center of mass of the compressor 200. The compressor 200 has a rotating shaft (not shown) extending in a direction S. Generally, the compressor 200 operates to generate vibration in two directions: vibration in the vertical direction V and vibration in the rotational direction R.

With continued reference to fig. 1-3, the damping mechanism 100 includes a plurality of resilient elements 1, each of the resilient elements 1 having a resilient center, the resilient centers being generally understood in the art. The elastic centers are not completely located in the same plane and form a three-dimensional buffering space 10 together, and the center of mass of the compressor 200 is located in the buffering space 10, that is, the buffering space 10 is used for accommodating the center of mass of the compressor 200. With the arrangement, the vibration reduction mechanism 100 can effectively reduce vibration of the compressor 200 in the vertical direction V and can also effectively reduce vibration of the compressor 200 in the rotation direction R, so that the vibration reduction effect of the vibration reduction mechanism 100 on the compressor 200 is greatly improved. The elastic element 1 is a rubber member or a spring. The elastic centers are all located on the edge of the buffer space 10. The damping space 10 has a geometric center, and the center of mass is completely coincident with the geometric center. The closer the center of mass of the compressor 200 is to the geometric center of the buffering space 10, the better the vibration damping effect of the compressor 200 is, and when the two are completely overlapped, the best vibration damping effect is.

Likewise, the elastic element 1 for forming the secondary vibration damping may be disposed on the second bracket 22, on the mounting base 3, or partially on the second bracket 22 and partially on the mounting base 3. The arrangement is such that the vibration damping mechanism 100 forms two-stage vibration damping, and vibration generated by the compressor 200 is transmitted to the first bracket 21 first, is damped for the first time (first-stage vibration damping) when the vibration is transmitted to the elastic element 1 at the joint of the first bracket 21 and the second bracket 22, and is damped for the second time (second-stage vibration damping) when the vibration is transmitted to the elastic element 1 at the joint of the second bracket 22 and the mounting base 3. The elastic element 1 for creating the secondary damping also filters the vibration excitations generated on the ground. Of course, in other embodiments, the damping mechanism 100 may not include the mounting seat 3, but the second bracket 22 may be directly mounted to, for example, the chassis of the vehicle, in which case the elastic element 1 for forming the secondary damping is disposed on the second bracket 22.

The outer layer 12 and the inner layer 11 can move relatively, and the two connecting portions 13 are parallel to or coincident with the rotating shaft in the extending direction S of the rotating shaft. By arranging at least one elastic element 1 in the primary vibration reduction in the manner described above, the rigidity of the compressor 200 in the rotation direction R can be effectively reduced, and the vibration isolation effect can be improved.

Referring to fig. 5, 7 to 9, the core 5 has a stopper groove 52 formed at one side of the through hole 51, and the stopper washer 42 has a protrusion 421 extending into the stopper groove 52. During the process of installing the bolt 41, the bolt 41 passes through the through hole 51 and is rotatably fixed to the second bracket 22, and the limiting gasket 42 is prevented from following by the arrangement of the protruding part 421 and the limiting groove 52.

Preferably, the restriction 422 has a V-shape. When the movement of the inner layer 11 relative to the outer layer 12 along with the movement of the inner core 5 is large, the limiting part 422 directly or indirectly impacts the outer ring 6, so as to prevent the inner layer 11 and the outer layer 12 from being excessively displaced, and thus, the elastic element 1 can be prevented from being damaged by being excessively pulled. In this embodiment, the outer ring 6 has an end surface 61, the elastic element 1 is provided with an isolation buffer 14 at the end surface 61, when a large relative movement occurs between the outer layer 12 and the inner layer 11, the limiting portion 422 collides against the isolation buffer 14 on the side of the limiting portion 422, and the second bracket 22 collides against the isolation buffer 14 on the side of the second bracket 22, so that the isolation buffer 14 can improve the vibration damping effect.

Since the isolation buffer portion 14 is disposed at the end surface 61, the press-fitting tool cannot directly act on the outer ring 6, but only on the elastic isolation buffer portion 14, and thus it is difficult to press-fit the buffer assembly 4 in place. Through setting up breach 141 for outer ring 6 has great area to expose outside for the frock direct action, so set up, be favorable to the frock to buffering subassembly 4 pressure equipment location. Furthermore, the part of the elastic element 1 located in the notch 141 is flush with the end surface 61, so that the arrangement of a tool is facilitated, and the press mounting and positioning of the buffer assembly 4 by the tool are facilitated. In this embodiment, the gap 141 is formed by the gap between the multi-section isolation buffer parts 14. The position of the limiting portion 422 needs to correspond to the isolation buffer portion 14, the less the portion corresponding to the notch 141, the better, and preferably not, the protrusion 421 and the limiting groove 52 can ensure that the corresponding relationship will not change due to vibration.

With the arrangement, the outer ring 6 and the mounting hole 20 form reverse buckles at two ends, so that the buffer assembly 4 can be prevented from being separated from the bracket 2 due to overlarge vibration in the use process. Compared with the arrangement of the inclined or curved guide surface on the outer ring 6 and the arrangement of the interference fit convex part on the bracket 2, the strength of the outer ring 6 can be ensured, the buffer component 4 is protected, and the service life of the product is prolonged.
