[0020] The following further describes the present invention in conjunction with embodiments, but is not limited to the content in the specification.

[0021] The present invention is mainly applied to the compressor on a marine air conditioner. Considering that when a ship is sailing at sea, it often encounters the beating of waves, and the hull will suddenly tilt and swing. In addition, the vibration of the ship's engine will also cause the vibration of the hull. Therefore, for the compressor of a marine air conditioner, it must undergo a vibration test. The traditional way to fix the compressor is to fix the compressor on the bracket together with the compressor positioning bolts, compressor nuts and compressor vibration damping gaskets. However, we found in the test that this fixing method cannot meet the standards under strong vibration impact, and the compressor will have a large amplitude of vibration, affecting the operation safety of the air conditioner.

[0022] Under such harsh working conditions of severe vibration, an ordinary compressor fixed by bolts has no vibration damping ability, and if a compressor vibration damping rubber pad is used, it cannot meet the requirements either. The compressor is fixed by positioning bolts and nuts. Firstly, the fixing ability of a single bolt and nut is poor. Secondly, the friction between the vibration damping rubber pad and the nut will also cause the nut to loosen.

[0023] The present invention discloses a vibration damping assembly, including: a vibration damping foot pad 10 and a gland 20. The vibration damping foot pad 10 has an installation groove 121 for installing the compressor fixing part 51; the gland 20 is arranged on the vibration damping foot pad 10, and the gland 20 is used to apply a pre-tightening force to the vibration damping foot pad 10 under the action of an external force, so that the installation groove 121 elastically deforms to clamp and fix the compressor fixing part 51 in the installation groove 121. The vibration damping assembly of the present invention sets a gland 20 on the vibration damping foot pad 10, so that the gland 20 applies a pre-tightening force to the vibration damping foot pad 10 under the action of an external force, and the installation groove 121 elastically deforms to clamp and fix the compressor fixing part 51 in the installation groove 121, making it more stable and reducing the vibration amplitude of the compressor during the strong large-amplitude vibration of the air conditioner.

[0024] In the above embodiment, the gland 20 has a limit protrusion 21, and the limit protrusion 21 is located on the side of the gland 20 facing the compressor fixing part 51. Under the action of the pre-tightening force, the gland 20 presses the limit protrusion 21 against the compressor fixing part 51. The vibration damping assembly of the present invention increases the gland. Under the action of an external force, the gland 20 will press the vibration damping foot pad 10 downward, and the limit protrusion 21 of the gland and the compressor fixing part 51 are closely combined, so that the compressor will not shake upward due to strong vibration, greatly improving the overall vibration resistance ability of the compressor, meeting the requirements of GJB vibration and impact, and being very stable.

[0025] In the above embodiments, the vibration damping assembly further includes: a connecting member 30. The connecting member 30 passes through both the vibration damping foot pad 10 and the gland 20 at the same time. The vibration damping foot pad 10 is installed on the fixed bracket 40 of the compressor through the connecting member 30. The connecting member 30 is also used to apply an external force to the gland 20. By adding a gland, the fixing ability of the fixing part 51 of the compressor is greatly enhanced in the vibration damping assembly of the present invention. The connecting member 30 and the gland can also be tightly combined. Under the action of the pre-tightening force of the connecting member 30, the gland will press the vibration damping foot pad downward, so that the compressor will not shake upward due to strong vibration, and the overall vibration resistance of the compressor is greatly improved, meeting the requirements of GJB for vibration and shock, and is very stable.

[0026] In the above embodiments, the connecting member 30 further includes: a bolt 31 and a nut 32. The bolt 31 passes through the fixed bracket 40, the vibration damping foot pad 10 and the gland 20 of the compressor at the same time. The head of the bolt 31 is located at the position of the fixed bracket 40, and the tail of the bolt 31 is located at the position of the gland 20. The nut 32 is installed at the tail of the bolt 31. The gland 20 is located between the vibration damping foot pad 10 and the nut 32. The vibration damping foot pad 10 is installed on the fixed bracket 40 through the bolt 31 and the nut 32. When the nut 32 rotates, an external force is applied to the gland 20, so that the gland 20 applies a pre-tightening force to the vibration damping foot pad 10. By providing a bolt and a nut in the vibration damping assembly of the present invention and arranging the gland between the nut and the vibration damping foot pad, the fixing ability of the fixing part 51 of the compressor is greatly enhanced. The nut and the gland can also be tightly combined. Under the action of the pre-tightening force of the nut, the gland will press the vibration damping foot pad downward, so that the compressor will not shake upward due to strong vibration, and the nut will not loosen easily, and the overall vibration resistance of the compressor is greatly improved. Meeting the requirements of GJB for vibration and shock, it is very stable.

[0027] In the above embodiments, the direction of the pre-tightening force is from the tail of the bolt 31 to the head of the bolt 31.

[0028] In the above embodiments, the vibration damping foot pad 10 includes: a main body 11 and a convex portion 12. The first end of the main body 11 is disposed on the fixing bracket 40; the convex portion 12 is located at the second end of the main body 11 and is connected to the main body 11. An installation groove 121 is formed between the convex portion 12 and the main body 11; the gland 20 is disposed on the convex portion 12. The convex portion 12 is deformed after being subjected to the pre-tightening force of the gland 20 to squeeze the fixing bracket 40. The installation groove 121 is an annular groove. The compressor fixing portion 51 is sleeved in the installation groove 121, and the convex portion 12 is located between the gland 20 and the compressor fixing portion 51. By providing the convex portion 12 on the main body 11 in the vibration damping assembly of the present invention, under the action of the pre-tightening force of the bolt and the nut, the gland will press down the convex portion 12 tightly. The convex portion 12 is deformed after being subjected to the pre-tightening force of the gland 20 to squeeze the fixing bracket 40. At the same time, the limit projection 21 of the gland 20 will be closely combined with the compressor fixing portion 51. The two cooperate with each other to play a dual limiting role, so that the compressor will not shake upward due to strong vibration, and the nut will not loosen easily, greatly improving the overall vibration resistance of the compressor, meeting the GJB vibration and shock requirements, and being very stable.

[0029] In the above embodiments, the vibration damping foot pad 10 is provided with an installation hole 111 for installing the bolt 31, and the installation hole 111 penetrates through the main body 11 and the convex portion 12.

For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the embodiments here.
