For example, as shown in fig. 1 to 3, a first embodiment of the present utility model proposes a compressor, including a housing 100, a supporting member 200, a pump body, a motor 400 and a plurality of vibration damping assemblies 500, the housing 100 is provided with a containing cavity 110, the supporting member 200, the pump body, the motor 400 and the plurality of vibration damping assemblies 500 are all disposed in the containing cavity 110, the supporting member 200 is connected with a bottom wall of the housing 100, the pump body includes a crank case 310, a cylinder body, a piston, a connecting rod and a crankshaft 320, the crankshaft 320 is vertically installed in the crank case 310, the cylinder body is disposed on an upper side of the crank case 310, the cylinder body has a cylinder cavity, one end of the connecting rod is connected with the piston, the other end of the connecting rod is connected with an eccentric portion of the crankshaft 320, the piston can reciprocate in the cylinder cavity under the driving of the rotational motion of the crankshaft 320, the motor 400 includes a stator 410 and a rotor 420 rotatably disposed in the stator 410, the stator 410 is fixedly connected with the crankshaft 320, the vibration damping assemblies 500 are connected between the supporting member 200 and the stator 410, and the plurality of vibration damping assemblies 500 are circumferentially spaced around the crankshaft 320, the crank case 320, the vibration damping assemblies 500 include a spring 510 and an elastic sleeve 520 coaxially disposed around the crankshaft, the crankshaft 520, the elastic sleeve 520 is disposed around the crankshaft 510, the crankshaft 520 is disposed around the crankshaft 310, the crankshaft and the crankshaft 510, the elastic sleeve is capable of completely compressing the stator 510 and the stator 510, and the stator 510 can completely and the stator 410 and the stator are completely and the stator 510 are capable of compressing the vibration sleeve and the stator 510, and the stator 510 can completely and the vibration spring 510 can be compressed by the elastic sleeve and the elastic sleeve 510 and the vibration sleeve can be completely.

For example, when the compressor works, the stator 410 drives the rotor 420 to drive the crankshaft 320 to rotate, the eccentric part of the crankshaft 320 drives the piston to reciprocate in the cylinder cavity through the connecting rod under the driving of the rotational motion of the crankshaft 320, so as to compress the refrigerant in the cylinder cavity, and since the piston, the connecting rod and the crankshaft 320 are in a high-speed motion state, the stator 410 and the crankcase 310 can generate certain vibration, and when the stator 410 and the supporting member 200 press the spring 510 and the elastic sleeve 520, the spring 510 and the elastic sleeve 520 generate elastic deformation to absorb the vibration energy of the stator 410 and the crankcase 310, the double vibration damping can be performed on the stator 410 and the crankcase 310, so that the vibration transmitted by the stator 410 and the crankcase 310 to the housing 100 can be reduced, the resonance of the housing 100 can be avoided, and the noise generated when the compressor works can be reduced.

It should be noted that, along the radial direction of the spring 510, the spring 510 and the elastic sleeve 520 may also partially overlap, for example, along the axial direction of the crankshaft 320, where the length of the spring 510 is greater than the length of the elastic sleeve 520, or where the length of the elastic sleeve 520 is greater than the length of the spring 510, which is not limited herein.

It should be noted that the vibration damping assemblies 500 are uniformly spaced around the circumference of the crankshaft 320, so that the vibration damping assemblies 500 are uniformly stressed, which is beneficial to improving the vibration damping effect of the vibration damping assemblies 500, and will not be described herein.

Referring to fig. 5, fig. 5 is an assembled schematic view of another implementation of a vibration reduction assembly of an embodiment of the present utility model. For example, as shown in fig. 5, as another embodiment, the positions of the spring 510 and the elastic sleeve 520 may be interchanged, that is, the spring 510 is sleeved on the outer periphery of the elastic sleeve 520, and the double vibration damping can be performed on the stator 410 and the crankcase 310, which is not limited herein.

The fact that the spring 510 is coaxially disposed with the elastic sleeve 520 means that the axis of the spring 510 is collinear with the axis of the elastic sleeve 520, or that the axis of the spring 510 is offset from the axis of the elastic sleeve 520 by a certain distance on the basis that the elastic sleeve 520 is sleeved on the spring 510 or the elastic sleeve 520 is sleeved on the spring 510, is not limited herein.

It should be noted that one or more elastic sleeves 520 may be provided, and when a plurality of elastic sleeves 520 are provided, a plurality of elastic sleeves 520 are coaxially provided, and the spring 510 is disposed through the innermost elastic sleeve 520, or the spring 510 is disposed around the outermost elastic sleeve 520, or the elastic sleeve 520 is disposed between two adjacent elastic sleeves 520, which is not limited herein.

It should be noted that, when the elastic sleeve 520 is configured with a plurality of elastic sleeves, the elastic sleeve 520 may be disposed on the outer periphery of the spring 510, and the elastic sleeves 520 are disposed along the circumferential direction of the spring 510 at intervals, so that multiple vibration reduction can be performed on the stator 410 and the crankcase 310, and noise generated during operation of the compressor can be reduced, which is not repeated herein.

In this embodiment, the upper end of the spring 510 abuts against the lower end face of the stator 410, the lower end of the spring 510 abuts against the support member 200, the upper end of the elastic sleeve 520 abuts against the lower end face of the stator 410, the lower end of the elastic sleeve 520 abuts against the support member 200, and the vibration of the stator 410 and the crankcase 310 is directly transmitted to the support member 200 through the spring 510 and the elastic sleeve 520, so that the assembly materials of the compressor can be reduced while the vibration of the stator 410 and the crankcase 310 transmitted to the housing 100 is damped, the assembly process of the compressor is simplified, and the assembly materials of the compressor are improved.

As another embodiment, the upper end of the spring 510 may be abutted with the lower end surface of the stator 410 through the first gasket, and/or the lower end of the spring 510 may be abutted with the support 200 through the second gasket, and/or the upper end of the elastic sleeve 520 may be abutted with the lower end surface of the stator 410 through the third gasket, and/or the lower end of the elastic sleeve 520 may be abutted with the support 200 through the fourth gasket, and also the vibration transmitted to the housing 100 from the stator 410 and the crankcase 310 may be damped, which is not limited herein.

It will be appreciated that the first, second, third and fourth shims may be rigid or resilient, without limitation.

For example, as shown in fig. 3, in order to avoid noise caused by collision between adjacent wires of the spring 510, in this embodiment, the elastic sleeve 520 is sleeved on the spring 510, and the inner circumferential surface of the elastic sleeve 520 is abutted against the outer circumferential surface of the spring 510, so that even if the stator 410 and the crankcase 310 generate a large amount of shake, the elastic sleeve 520 can limit the radial swing of the spring 510 along the spring 510, and collision between adjacent wires of the spring 510 can be avoided, thereby effectively reducing noise generated when the compressor operates.

In another embodiment, the spring 510 is sleeved on the elastic sleeve 520, and the outer circumferential surface of the elastic sleeve 520 is abutted against the inner circumferential surface of the spring 510, so that the spring 510 can be limited from swinging along the radial direction of the spring 510, which is not described herein.

For example, as shown in FIG. 3, in the present embodiment, the minimum wall thickness of the elastic sleeve 520 is T, which satisfies that T is less than or equal to 1mm and less than or equal to 3mm, on one hand, the structural strength of the elastic sleeve 520 can be ensured to improve the service life of the elastic sleeve 520 and reduce the swing amplitude of the spring 510, and on the other hand, the axial rigidity of the elastic sleeve 520 can be reduced, so that the elastic sleeve 520 can effectively buffer the stator 410 and the crankcase 310.

For example, if the wall thickness of the elastic sleeve 520 is smaller than 1mm, the wall thickness of the elastic sleeve 520 is too small, when the elastic sleeve 520 receives a tangential force, the tangential deformation of the elastic sleeve 520 is too large and is easy to break, the service life of the elastic sleeve 520 is low, the swing amplitude of the spring 510 cannot be reduced, the adjacent wires of the spring 510 are easy to collide, and if the wall thickness of the elastic sleeve 520 is larger than 3mm, the axial rigidity of the spring 510 is too large, which is not beneficial to buffering the vibration of the stator 410 and the crankcase 310, and the noise generated during the operation of the compressor is large. Therefore, by designing the wall thickness of the elastic sleeve 520 to be 1mm to 3mm, the tangential stiffness of the elastic sleeve 520 can be ensured, the axial stiffness of the elastic sleeve 520 can be reduced, and the noise generated when the compressor works can be reduced.

The elastic wall thickness T may be 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, and 3mm, which is not limited herein.

Referring to fig. 3 and 4, fig. 4 is a top view of a vibration damping assembly according to an embodiment of the present utility model. For example, as shown in fig. 3 and 4, in the present embodiment, the elastic sleeve 520 is sleeved on the spring 510, the spring 510 has a seat spring structure, the spring 510 includes a main body 511 and an abutment portion 512, the lower end of the main body 511 abuts against the support 200, the upper end of the main body 511 is connected to the abutment portion 512, and the abutment portion 512 extends spirally to the inner side of the main body 511, so that the contact area between the spring 510 and the stator 410 can be increased, and the connection reliability between the spring 510 and the stator 410 can be improved.

For example, the upper side of the abutting portion 512 abuts against the lower side of the stator 410, and the lower end of the main body portion 511 abuts against the supporting member 200, and the abutting portion 512 extends spirally to the inner side of the main body portion 511, so that the contact area between the spring 510 and the stator 410 can be increased, and the connection reliability between the spring 510 and the stator 410 can be improved.

In another embodiment, the spring 510 may be a compression spring 510, which is capable of damping vibration generated when the stator 410 and the crankcase 310 are operated, and is not limited thereto.

For example, when the spring 510 is assembled, the rod 620 sequentially penetrates through the through hole 513, the through hole and the threaded hole from bottom to top, and the abutting portion 512 is clamped between the head 610 and the stator 410, so that the abutting portion 512 is fixedly connected with the stator 410, the stator 410 and the crankcase 310 are in an integral structure, the abutting portion 512 moves along with the vibration of the stator 410 and the crankcase 310, and the main body 511 and the elastic sleeve 520 can buffer the vibration transmitted to the abutting portion 512 by the stator 410 and the crankcase 310, respectively, so as to attenuate the vibration transmitted to the casing 100 by the stator 410 and the crankcase 310, and reduce the noise generated during the operation of the compressor.
