The specific arrangement can be set according to actual needs. The second arc surface 160 is arranged on the outer wall of the second support section 118. Since the first arc surface 150 is concave inward, the second arc surface 160 is convex outward, that is, the wall thickness of the second support section 118 is greater than the wall thickness of any one of the first support section 117 and the third support section 119, that is, the wall thickness of the support section 116 near the middle position of the damping pad 110 is large, so that the damping effect of the damping pad 110 can be improved, the vibration noise of the refrigeration equipment during operation can be reduced, the stiffness of the damping pad 110 can be ensured, the stress deformation of the damping pad 110 caused by insufficient stiffness can be avoided, and the anti-deformation ability of the damping pad 110 can be further improved.

[0059] As shown in Figure 1 , Figure 2 and Figure 3 In some embodiments, the damping pad assembly 100 also includes a matching part 170 and a groove 180, wherein the matching part 170 is arranged on the damping pad 110 and is used for matching connection with the base 220 of the compressor 200, and the groove 180 is arranged on the side of the damping pad 110 away from the matching part 170, and the groove 180 is through the outer wall of the damping pad 110.

In this way, the deformation of the damping pad 110 under compression in the axial direction is prevented, the deformation resistance of the damping pad 110 is improved, and the service life of the damping pad assembly 100 is prolonged.

[0066] In addition, the contact between the first plane 121 and the second plane 131 can increase the contact area between the support portion 120 and the support boss 130, improve the supporting effect of the support boss 130 on the support portion 120, avoid excessive compression of the damping pad 110 in the axial direction, and further improve the deformation resistance of the damping pad 110.

[0077] According to the third aspect of the utility model, provide a kind of refrigeration equipment, including the damping pad assembly 100 or compressor 200 provided by any of the above embodiments, thus have the entire beneficial technical effects of the damping pad assembly 100 or compressor 200, here no longer repeat.

[0078] Optionally, refrigeration equipment includes refrigerator, air conditioner or freezer.

[0079] As Figure 1 、 Figure 2 And Figure 3 Indicated, in one specific embodiment, compressor 200 has shell (main body 210) and base 220, refrigeration equipment has bottom plate 300, and the base 220 of compressor 200 is connected and installed on the bottom plate 300 of refrigeration equipment by bolt (fastener 230) with rubber pad (damping pad assembly 100).

[0080] Rubber pad (damping pad assembly 100) has hollow portion (damping cavity 111) and support part (support part 120 and support boss 130) inside, while reducing the rigidity of rubber pad, can guarantee that rubber pad is prevented from being compressed deformation when being compressed in axial force.

[0081] The outer shape of the rubber pad (vibration damping pad assembly 100) is wavy, the middle part (second support section 118) is convex, and the wall thickness is uneven, which can improve the vibration isolation capacity and deformation resistance of the rubber pad. In detail, the support part 120 and the support boss 130 are arranged in the damping cavity 111 respectively and connected with the damping pad 110. In the axial direction of the damping pad 110, the support part 120 is opposite to the support boss 130, and the support part 120 and the support boss 130 have a spacing therebetween. Since at least part of the support boss 130 extends axially, when the damping pad 110 is compressed in the axial direction during the operation of the refrigeration equipment or under abnormal conditions, that is, the support part 120 moves to the first position, the support part 120 is supported by the support boss 130, thereby ensuring the vibration isolation capacity of the damping pad 110, preventing the damping pad 110 from being compressed and deformed in the axial direction, improving the deformation resistance of the damping pad 110, and prolonging the service life of the vibration damping pad assembly 100.

[0082] The bottom of the rubber pad (vibration damping pad assembly 100) has a groove 180, which can reduce the contact area and reduce vibration transmission without affecting the deformation resistance of the rubber pad.

[0083] Through the optimized design of the structure, the stiffness of the rubber pad (vibration damping pad assembly 100) is reduced, the vibration isolation capacity of the rubber pad is improved, the vibration noise is reduced, and the deformation of the rubber pad caused by insufficient stiffness is avoided.

[0084] In addition, the rubber pad for the compressor in the related art has obvious resonance noise at the fundamental frequency (80 Hz) when matched with the refrigerator. According to the noise test results, the vibration damping pad assembly 100 of the present application has significantly reduced noise at the fundamental frequency (80 Hz) compared with the rubber pad in the related art, and the listening experience is significantly improved.
