It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be capable of being practiced otherwise than as specifically illustrated and described.
As shown in fig. 1 and 2, a vibration damping structure of a compressor includes a compressor 1, a support frame 2, and a base plate 3. The support frame 2 includes an upward vertically extending arm 21, the compressor 1 is vertically disposed, and a mounting rod 11 extending outward in the radial direction of the compressor 1 is provided on a side wall of the compressor 1, and in the axial direction of the compressor 1, the mounting rod 11 is located above the center position of the compressor 1, the mounting rod 11 being connected to the arm 21 so that the support frame 2 can support the compressor 1 through the mounting rod 11. The supporting frame 2 is coupled to the base plate 3 with the first vibration damping member 4 interposed therebetween to damp vibration of the compressor 1. Wherein the first vibration damping member 4 may be made of an elastic material (e.g., rubber).
The support frame 2 is supported on the compressor 1 through the support arm 21 and is close to the position at the top of the compressor 1 to through the vibration of first damping part 4 buffering compressor, can concentrate the vibration energy at the top of compressor 1 to the lower part of compressor 1, because the vibration amplitude at the during operation top of compressor 1 is the biggest, consequently adopt such technical scheme, can effectively alleviate the vibration of compressor 1, and then reduced the running noise of compressor. In actual manufacture, as shown in fig. 1 and 2, the number of the mounting rods 11 is at least two (in this embodiment, the number of the mounting rods is two), at least two mounting rods 11 are uniformly distributed along the circumferential direction of the compressor 1, and the number of the support arms 21 is equal to and corresponds to the number of the mounting rods 11 one by one. This enables a stable support of the compressor by means of the plurality of arms 21, thus ensuring the stability of the compressor 1.
Preferably, as shown in fig. 3, the top end of the arm 21 is provided with a bearing groove 22, and the mounting rod 11 is located in the bearing groove 22 and can rotate in the bearing groove 22. This not only prevents the mounting rod 11 from falling off from the top end of the arm 21, but also allows the mounting rod 11 to rotate in the bearing groove 22 when the compressor 1 swings, so as to prevent the swinging force of the compressor 1 from being transmitted to the arm 21. More preferably, the outer surface of the mounting rod 11 is provided with a first clamping groove 12 extending along the circumferential direction, and the mounting rod 11 is clamped on the bearing groove 22 through the first clamping groove 12, so that the compressor 1 can be positioned opposite to the support arm 21 in the radial direction.
As an embodiment, as shown in fig. 1 and 2, the support frame 2 further includes a limiting ring 23 with a central axis extending along a vertical direction, the limiting ring 23 is sleeved on the compressor 1, and a second vibration reduction component 5 is disposed between an inner wall of the limiting ring 23 and a side wall of the compressor 1 to buffer radial vibration of the compressor 1, and a bottom end of the support arm 21 is fixedly connected to the limiting ring 23. In this way, the vibration of the compressor 1 in the radial direction can be damped by the second vibration damping member 5, and the vibration damping effect is further improved. The second damper member 5 is a compression spring, but is not limited thereto, and any other member that can achieve the object of the present invention may be used. Preferably, the stop collar 23 is located below the central position of the compressor 1, i.e. the stop collar 23 is sleeved on the lower part of the compressor 1. Because the support frame 2 is supported on the compressor 1 through the support arm 21 and is close to the position at the top end of the compressor 1, the vibration energy at the top end of the compressor 1 is concentrated to the lower part of the compressor 1, and therefore the second vibration reduction component 5 can be sleeved on the lower part of the compressor 1 through the limiting ring 23, and the radial vibration of the lower part of the compressor 1 can be directly relieved, and the vibration reduction effect is more obvious.
Further, as shown in fig. 2 and 4, a connecting groove 24 is provided on the inner wall of the limit ring 23, and two ends of the second vibration reduction component 5 are a first end and a second end, respectively, and the first end is located in the connecting groove 24.

This ensures that the second damping part 5 is mounted with stability, avoiding its relative displacement with the stop ring 23 and/or with the side wall of the compressor 1. In actual production, the number of the second vibration reduction parts 5 may be at least two (the technical scheme of one second vibration reduction part 5 is shown in the drawing), and the at least two second vibration reduction parts 5 are uniformly distributed along the circumferential direction of the compressor 1.
As an alternative embodiment, as shown in fig. 1 and 5, a connecting bolt 6 is also included. The mounting plate 25 is arranged on the outer wall of the limiting ring 23, the mounting plate 25 is provided with a first mounting hole 26, the bottom plate 3 is provided with a second mounting hole 31, the connecting bolt 6 is arranged in the first mounting hole 26 and the second mounting hole 31 in a penetrating mode to connect the support frame 2 on the bottom plate 3, and the first vibration reduction part 4 is connected between the mounting plate 25 and the bottom plate 3. In this way, the axial vibration force of the compressor 1 can be transmitted to the first vibration reduction member 4 through the support frame 2, so that the first vibration reduction member 4 can alleviate the axial vibration of the compressor 1 through elastic deformation. In actual manufacturing, as shown in the figure, the mounting plate 25 is arranged on the outer wall of the limiting ring 23 at a position corresponding to the support arm 21, and at this time, when the axial vibration of the compressor 1 occurs, the axial vibration force can be directly transmitted to the mounting plate 25 through the support arm 21, and the first vibration reduction component 4 is transmitted through the mounting plate 25, so that the vibration reduction effect is better.
Specifically, as shown in fig. 5, the first vibration reducing member 4 has a through hole 41, and is fitted over the connecting bolt 6 through the through hole 41 to ensure stability of the first vibration reducing member 4 disposed between the mounting plate 25 and the bottom plate 3.
Preferably, as shown in fig. 5, the first vibration reduction member 4 includes a limiting portion 42, and is penetrated into the first mounting hole 26 by the limiting portion 42 to connect the first vibration reduction member 4 to the first mounting hole 26. In this way, the axial vibration force of the compressor 1 can be transmitted to the limiting portion 42 penetrating the first mounting hole 26 through the supporting frame 2, so that the radial vibration of the compressor 1 can be relieved by the limiting portion 42 through elastic deformation. More preferably, the limiting portion 42 is provided with a second clamping groove 43, and is clamped in the first mounting hole 26 through the second clamping groove 43, so that the limiting portion 42 can be stably connected in the first mounting hole 26, and the stability of the first vibration reduction component 4 is further improved.
In practical manufacturing, as shown in fig. 1 and 2, the number of the mounting plates 25 is at least two, at least two mounting plates 25 are uniformly distributed along the axis of the limiting ring 23, and the number of the second mounting holes 31 is equal to and corresponds to the number of the mounting plates 25 one by one.
