[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] Hereinafter, the compression mechanism portion 100 according to an embodiment of the present invention will be described with reference to the drawings.

[0043] like Figure 1-Figure 12 As shown, the compression mechanism part 100 according to an embodiment of the present invention includes: a rotating shaft 1, an eccentric sleeve 2, a first limiting member, a second limiting member and an elastic member 4. The eccentric sleeve 2 is eccentrically arranged on the rotating shaft 1 through a first connecting member 3, and the first rotation axis 2a of the eccentric sleeve 2 and the second rotation axis 1a of the rotating shaft 1 are arranged at intervals; the first limiting member is arranged on the rotating shaft 1, and the second limiting member is arranged on the eccentric sleeve 2. One of the first limiting member and the second limiting member is a limiting groove 21 and the other is a limiting column 11 inserted into the limiting groove 21; the elastic member 4 is connected to the first connecting member 3, and the elastic member 4 is fixedly connected to the rotating shaft 1 and the eccentric sleeve 2 respectively.

[0044] Thus, the collision force between the limiting column 11 and the peripheral wall of the limiting groove 21 can be reduced or eliminated, which is beneficial to reducing noise and can increase the service life of the compression mechanism part 100.

[0045] For example, refer to Fig.11 As shown, the compression mechanism 100 is suitable for being installed in the low-pressure chamber 201 of the compressor 200. The compression mechanism 100 includes a rotating shaft 1 and an eccentric sleeve 2. The rotating shaft 1 is used to be connected to the motor 202 so that the motor 202 can drive the rotating shaft 1 to rotate around the second rotation axis 1a (i.e., its own axis). Figure 1-Figure 5 As shown, a first connecting member 3 is installed at one end of the rotating shaft 1 facing the eccentric sleeve 2. The first connecting member 3 is constructed as a pin structure. The axis of the first connecting member 3 remains parallel to the second rotation axis 1a, and a mounting through hole is provided on the eccentric sleeve 2. The first connecting member 3 is used to be inserted into the mounting through hole and fixedly connected to the eccentric sleeve 2 through a clamping block 31, so that the eccentric sleeve 2 can be eccentrically arranged at one end of the rotating shaft 1 through the first connecting member 3.

[0046] The eccentric sleeve 2 can rotate around the axial direction of the first connecting member 3, that is, the first rotation axis 2a of the eccentric sleeve 2 is spaced apart from the second rotation axis 1a of the rotating shaft 1. The eccentric sleeve 2 is used to be connected to the movable scroll 203 of the compression part, so that the rotating shaft 1 can drive the scroll 203 to move through the eccentric sleeve 2, so that the compression part can compress the low-pressure refrigerant.

[0047] The compression mechanism 100 further includes a first limiting member and a second limiting member, wherein the first limiting member is arranged at one end of the eccentric sleeve 2 that rotates, and the second limiting member is arranged at the side of the eccentric sleeve 2 that faces the rotating shaft 1 and is arranged opposite to the first limiting member, and one of the first limiting member and the second limiting member is a limiting groove 21 and the other is a limiting column 11. For example, the first limiting member can be set as the limiting groove 21 and the second limiting member can be set as the limiting column 11, or the second limiting member can be set as the limiting groove 21 and the first limiting member can be set as the limiting column 11, and the present invention does not limit this. The limiting column 11 is used to extend into the limiting groove 21 and to cooperate with the peripheral wall of the limiting groove 21. When the compressor 200 is running and causes the eccentric sleeve 2 to rotate relative to the rotating shaft 1 around the first rotation axis 2a, the limiting column 11 can be stopped and cooperated with the peripheral wall of the limiting groove 21 to limit the rotation angle of the eccentric sleeve 2.

[0048] The compression mechanism 100 further includes an elastic member 4, and avoidance grooves 24 are respectively provided on both sides of the eccentric sleeve 2. The eccentric sleeve 2 and the rotating shaft 1 are suitable for defining an installation space in the avoidance grooves 24. The elastic member 4 is installed in the installation space and is used to be connected with the first connecting member 3, and the two ends of the elastic member 4 can also be fixedly connected with the rotating shaft 1 and the eccentric sleeve 2, respectively. In this way, when the eccentric sleeve 2 rotates around the second rotation axis 1a relative to the rotating shaft 1, the elastic member 4 can be deformed to generate a circumferential elastic force, and the elastic force is used to limit the eccentric sleeve 2 and the rotating shaft 1, thereby slowing down or eliminating the collision between the limiting column 11 and the peripheral wall of the limiting groove 21, and reducing noise.

[0049] In addition, when the first connecting member 3 moves relative to the eccentric sleeve 2 or the rotating shaft 1, the elastic member 4 can apply a limiting force to the first connecting member 3 to reduce the vibration of the first connecting member 3, which is conducive to reducing noise.

[0050] According to the compression mechanism part 100 of the embodiment of the present invention, an elastic member 4 is connected to the first connecting member 3, and the elastic member 4 is respectively connected to the rotating shaft 1 and the eccentric sleeve 2. When the rotating shaft 1 and the eccentric sleeve 2 rotate relative to each other, the elastic member 4 can be deformed to generate an elastic force, and the elastic force is used to mitigate or eliminate the collision between the limiting column 11 and the surrounding wall of the limiting groove 21, which is beneficial to reducing the noise of the compression mechanism part 100 and can increase the service life of the compression mechanism part 100.
