Meanwhile, the structure is simple and easy to process and realize.
In the present embodiment, three connection portions 31 are located at the middle and both ends of the support structure 30, respectively.
The number of the connection portions 31 is not limited to this. Optionally, the support structure 30 comprises four, five or more connections 31.
In the present embodiment, the connection portion 31 is welded to the compressor body 10. Specifically, the three connection portions 31 each have 1 to 5 bumps punched out on the surface facing the compressor body 10 for resistance welding. In this way, the above connection manner makes the connection between the support structure 30 and the compressor body 10 more stable, and improves the structural stability of the compressor.
The connection method between the connection portion 31 and the compressor body 10 is not limited to this. Alternatively, the connection portion 31 is riveted or connected with the compressor body 10 by a fastener. In this way, the connection mode improves the connection strength between the supporting structure 30 and the compressor body 10, prevents the supporting structure and the compressor body from being separated, and improves the structural reliability of the compressor.
As shown in fig. 3 and 4, a side of the connection portion 31 facing the compressor body 10 has an arc surface, and the arc surface is disposed to be fitted with an outer surface of the housing of the compressor body 10. In this way, the above arrangement can increase the contact area between the connection portion 31 and the compressor body 10, further increase the connection strength between the support structure 30 and the compressor body 10, and further improve the connection strength between the compressor body 10 and the liquid storage structure 20.

At the same time, the first and second connecting arms 33, 34 support the positioning support section 32 to provide a high radial and tangential support stiffness to the reservoir structure 20.
As shown in fig. 3 and 4, the first connecting arm 33 is smoothly connected to the positioning support section 32, and the second connecting arm 34 is smoothly connected to the positioning support section 32. In this way, the above arrangement can prevent stress concentration at the connection part of the first connecting arm 33 and the second connecting arm 34 and the positioning support section 32, thereby improving the structural strength of the support structure 30 and prolonging the service life thereof. At the same time, the above arrangement makes the appearance of the support structure 30 more attractive without scratching or cutting the staff.

In this way, the above arrangement ensures that the included angle between the connection line L2 and the connection line L1 is greater than 0 °, so that the positioning support section 32 supports the liquid storage structure 20, so as to realize the supporting and fixing effects of the support structure 30 on the liquid storage structure 20.
As shown in fig. 7, the first connecting portion 31 has one end near the second end of the arcuate plate-like segment and a center O 2 The connecting line L3 and the straight line L form an included angle alpha 2, and the second end of the arc-shaped platy section and the center O 2 The connecting line L4 and the straight line L form an included angle beta 2, and the angle beta 2 is more than 0 degree and less than or equal to 90 degrees.

As shown in fig. 2 and 3, the compressor further includes a crimp structure 40. Wherein, the compression joint structure 40 is in compression joint with the liquid storage structure 20 and is in fastening connection or clamping connection with the supporting structure 30. Specifically, the crimping structure 40 is fixedly connected with the connection part of the first connecting arm 33 and the positioning support section 32, and is clamped with the connection part of the second connecting arm 34 and the positioning support section 32. Thus, the above arrangement makes the mounting or dismounting of the support structure 30 and the press-connection structure 40 easier and simpler, and reduces the labor intensity of the staff.

It should be noted that, the connection manner of the support structure 30 and the liquid storage structure 20 is not limited thereto. Optionally, the support structure 30 is pressed out of the reservoir structure 20 by a tool.
As shown in fig. 3 to 5, the connection portion of the positioning support section 32 and the first connection arm 33 has a protrusion 322, the protrusion 322 is provided with a connection hole 321, and the fastener 60 is screwed at the connection hole 321 through the press-connection structure 40. Optionally, the extension of the projection 322 is tangential to the connection of the positioning support section 32 and the first connecting arm 33. In this way, the fastener 60 is threaded onto the protrusion 322, and thus does not affect the structural strength of the connection of the positioning support section 32 and the first connecting arm 33. Meanwhile, the above arrangement makes the connection of the crimping structure 40 and the supporting structure 30 easier and more convenient, and structural interference does not occur.

In this way, the above arrangement can further increase the contact area between the damper 50 and the press-contact structure 40 and the support structure 30, and improve the vibration damping efficiency and vibration-proof effect.
Example IV
The compressor of the fourth embodiment differs from that of the first embodiment in that: the support structure 30 is structurally different.

In this way, one side of the support structure 30 is connected to the crimping structure 40 by fasteners, thereby making the installation or removal of that side from the crimping structure 40 easier and more convenient.
As shown in fig. 11 and 13, the connection between the positioning support section 32 and the second connecting arm 34 is cut to form a clamping hole 323. Specifically, the clamping protrusion on the compression structure 40 corresponding to the clamping hole 323 extends into the clamping hole 323 and is matched with the clamping hole 323 in a clamping manner, so that the connection between the other side of the support structure 30 and the compression structure 40 is realized. The above connection mode makes the installation or the disassembly of the supporting structure 30 and the compression joint structure 40 easier and simpler, and reduces the labor intensity of staff.
In other embodiments not shown in the drawings, the connection between the positioning support section and the first connecting arm and the connection between the positioning support section and the second connecting arm are provided with connecting holes, and two fasteners respectively penetrate through the two connecting holes and then are screwed at the corresponding connecting holes. The above connection mode makes the installation or the disassembly of the supporting structure and the compression joint structure easier and simpler, and reduces the labor intensity of staff.
In other embodiments not shown in the drawings, the connection of the positioning support section and the first connecting arm and the connection of the positioning support section and the second connecting arm are cut to form the clamping holes. Specifically, the clamping protrusion corresponding to the clamping hole on the compression joint structure stretches into the clamping hole and is matched with the clamping hole in a clamping way, so that the support structure and the compression joint structure are connected. The structure is simple and easy to process and realize.
In other embodiments not shown in the drawings, the connection of the positioning support section and the first connecting arm is cut to form a clamping hole, the connection of the positioning support section and the second connecting arm is provided with a connecting hole, and the fastener passes through the crimping structure and is screwed at the connecting hole.
