[0001] The present invention relates to the technical field of compressor vibration reduction systems, and in particular to a vibration reduction device, a compressor and a refrigeration device. Background Art

[0002] At present, refrigerators are essential household appliances in daily life. Their main functions are freezing and refrigeration, and their refrigeration function is mainly achieved through compressors.

[0003] The compressor in the related art will generate large vibrations during repeated start-stop and high-load operation, causing the compressor to generate large noise during operation, resulting in large noise in the entire refrigerator during operation, affecting the user experience. Summary of the invention

[0004] The embodiments of the present invention are intended to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the present invention provides a vibration reduction device.

[0006] A second aspect of an embodiment of the present invention provides a compressor.

[0007] A third aspect of the embodiments of the present invention provides a refrigeration device.

[0008] In view of this, according to a first aspect of an embodiment of the present invention, a vibration damping device is provided, which is used for a compressor. The compressor includes a shell and a movement assembly, and the movement assembly is located in the shell. The vibration damping device includes: a first mounting member, used to connect the movement assembly; a second mounting member, used to connect the shell; a vibration damping assembly, the vibration damping assembly includes at least two vibration damping members, and the at least two vibration damping members are located between the first mounting member and the second mounting member, and connected to the first mounting member and the second mounting member.

[0009] The vibration reduction device provided in the embodiment of the present invention comprises a first mounting member, a second mounting member and a vibration reduction assembly. Specifically, the compressor comprises a housing and a core assembly, wherein the core assembly is located in the housing. It is understandable that the core assembly comprises a pump body and a driving member, and the driving member is connected to the pump body.

[0010] Specifically, when the compressor is repeatedly started and stopped and operates at high load, greater vibrations will be generated, resulting in greater vibration noise from the compressor, affecting the overall quality of the refrigeration equipment having the compressor.

[0011] The first mounting member is used to connect the movement assembly, the second mounting member is used to connect the shell, at least two vibration damping members are located between the first mounting member and the second mounting member, and at least two vibration damping members are connected to the first mounting member and the second mounting member, that is, the vibration damping assembly is installed on the compressor through the first mounting member and the second mounting member.

[0012] Since the vibration damping assembly includes at least two vibration damping parts, it can effectively attenuate the inertia force and inertia moment of the compressor during operation, reduce the vibration acceleration generated when the compressor is running, and further reduce the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0013] Optionally, at least one of the at least two vibration damping members is located inside at least one of the remaining vibration damping members. That is, after the at least two vibration damping members are formed into an inner-outer nested form, they are installed with the first mounting member and the second mounting member. This can further improve the vibration damping effect of the vibration damping device, and is also conducive to reducing the occupied space of the vibration damping device and improving the space utilization rate in the compressor housing.

[0014] Optionally, at least two vibration damping members are arranged adjacent to each other, that is, at least two vibration damping members are arranged side by side, which can also improve the vibration damping effect of the vibration damping device.

[0015] Optionally, at least one vibration damping member comprises a spring or a bellows or the like.

[0016] In addition, the vibration reduction device provided by the above technical solution of the present invention also has the following additional technical features:

[0017] In some technical solutions, optionally, the at least two vibration dampers include a first vibration damper and a second vibration damper, and the second vibration damper is located inside the first vibration damper.

[0018] In this technical solution, at least two vibration dampers are defined, including a first vibration damper and a second vibration damper. Specifically, the second vibration damper is located inside the first vibration damper, that is, the first vibration damper and the second vibration damper are formed in an inner and outer nested form, thereby improving the vibration damping effect of the vibration damping device, further attenuating the inertia force and inertia moment of the compressor during operation, reducing the vibration acceleration generated by the compressor during operation, and thereby reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device, and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0019] At the same time, since the second vibration damping member is located inside the first vibration damping member, it is also beneficial to reduce the space occupied by the vibration damping device in the radial direction and improve the space utilization rate in the compressor housing.

[0020] Optionally, the first vibration damper includes a first spring, and the second vibration damper includes a second spring. The first spring and the second spring are formed into an inside-outside nested structure, which can improve the overall stiffness of the first spring and the second spring, thereby improving the vibration damping effect of the vibration damping device, thereby achieving effective suppression of vibrations generated during the operation of the compressor.

[0021] In some technical schemes, optionally, the first mounting member includes a first bushing and a fastener, wherein the first end of the first vibration damper and the first end of the second vibration damper are arranged on the first bushing, the fastener is arranged on the side of the first bushing away from the second mounting member, and the first bushing is connected to the movement assembly through the fastener.

[0022] In this technical solution, it is defined that the first mounting member includes a first bushing and a fastener. Specifically, the first end of the first vibration damping member and the first end of the second vibration damping member are arranged on the first bushing, and the fastener is arranged on the side of the first bushing away from the second mounting member, that is, the fastener is located on the side of the first bushing close to the movement assembly. The first bushing is fixed to the movement assembly by the fastener.

[0023] The vibration reduction system in the related art adopts an Archimedes seat spring, and the Archimedes seat spring is directly fixed to the bottom of the motor stator through a stator screw. The other end of the seat spring is a through hole, which is installed on the seat spring bushing of the lower housing, and the seat spring bushing is fixed to the lower housing through a positioning pin. Since the seat spring is directly fixed to the bottom of the stator through the stator screw, it is easy to cause the seat spring to tilt, which is easy to cause the seat spring itself to vibrate and cause low-frequency noise.

[0024] The installation of the first bushing and the movement assembly is achieved through fasteners. That is to say, by setting the first bushing, the first end of the first vibration damper and the first end of the second vibration damper are indirectly fixed to the movement assembly, so that the first end of the first vibration damper and the first end of the second vibration damper can be effectively fixed while preventing the first vibration damper and the second vibration damper from tilting, thereby effectively avoiding the problem of flutter of the vibration damping assembly itself and increase of low-frequency noise due to the tilt of the first vibration damper or the second vibration damper, ensuring the vibration damping effect of the vibration damping device, and thereby improving the noise reduction effect during the operation of the compressor.

[0025] Optionally, the fastener comprises a screw.

[0026] In some technical schemes, optionally, the first bushing includes a first mating surface and a first limiting surface, wherein, along the radial direction of the movement assembly, the first end of the first vibration damper is against the first mating surface, the first limiting surface is connected to the first mating surface, and along the axial direction of the movement assembly, the first end of the first vibration damper is in contact with the first limiting surface.

[0027] In this technical solution, it is defined that the first bushing includes a first matching surface and a first limiting surface. Specifically, the first limiting surface is connected to the first matching surface.

[0028] The first limiting surface and the first matching surface are used to effectively fix the first end of the first vibration damper to the first bushing, thereby improving the installation stability of the first end of the first vibration damper and preventing the first end of the first vibration damper from moving or falling out during the operation of the compressor, thereby achieving an effective vibration damping effect of the vibration damping device, thereby effectively attenuating the inertia force and inertia moment of the compressor during operation, reducing the vibration acceleration generated during the operation of the compressor, and thus reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0029] Specifically, along the radial direction of the movement assembly, the first end of the first vibration damper abuts against the first mating surface, thereby achieving effective radial mating between the first end of the first vibration damper and the first bushing to prevent radial movement of the first end of the first vibration damper.

[0030] Along the axial direction of the movement assembly, the first end of the first vibration damper contacts the first limiting surface, thereby effectively limiting the first end of the first vibration damper in the axial direction, further improving the installation stability of the first end of the first vibration damper, and ensuring the vibration damping effect of the vibration damping device.

[0031] In some technical solutions, optionally, the cross-sectional shape of the first end of the first vibration damper is a first circular ring, and the first mating surface is a first cylindrical surface; the inner diameter d1 of the first circular ring and the diameter of the first cylindrical surface D1 satisfy 0.05mm≤d1-D1≤0.15mm.

[0032] In this technical solution, the cross-sectional shape of the first end of the first vibration damping member is a first circular ring, and specifically, the first vibration damping member includes a first spring. The first mating surface is a first cylindrical surface.

[0033] The difference between the inner diameter of the first annular ring and the diameter of the first cylindrical surface is between 0.05 mm and 0.15 mm. That is, the tolerance range between the minimum diameter of the inner ring of the first end of the first vibration damper and the maximum diameter of the first mating surface is limited. That is, the difference between the minimum inner contour size of the first end of the first vibration damper and the maximum outer contour size at the sleeve connection position of the first bushing and the first end of the first vibration damper is limited.

[0034] Thereby, the inner wall of the first end of the first vibration damper can be closely matched with the first mating surface, thereby achieving effective fixation between the first end of the first vibration damper and the first bushing, preventing the first end of the first vibration damper from radial movement, and thus achieving effective vibration damping effect of the vibration damping device, thereby effectively attenuating the inertia force and inertia moment of the compressor during operation, reducing the vibration acceleration generated when the compressor is running, and thus reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device, and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0035] In some technical solutions, optionally, the first bushing further includes a first recessed groove, the first recessed groove is located radially inward of the first mating surface, and the first end of the second vibration damper is embedded in the first recessed groove and abuts against an inner wall of the first recessed groove.

[0036] In this technical solution, it is defined that the first bushing also includes a first recessed groove. Specifically, along the radial direction of the movement assembly, the first recessed groove is located on the inner side of the first mating surface, and the first end of the second vibration damper is embedded in the first recessed groove, so that the second vibration damper is located inside the first vibration damper. In other words, the first vibration damper and the second vibration damper are formed in an inside-outside nested form, thereby improving the vibration damping effect of the vibration damping device, further attenuating the inertia force and inertia moment of the compressor during operation, reducing the vibration acceleration generated by the compressor during operation, and thereby reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device, and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0037] In addition, the first end of the second vibration damper abuts against the inner wall of the first sink groove, thereby achieving effective fixation of the first end of the second vibration damper, improving the installation stability of the first end of the second vibration damper, and preventing the first end of the second vibration damper from moving or falling out during the operation of the compressor, thereby achieving effective vibration reduction effect of the vibration damping device.

[0038] Moreover, embedding the first end of the second vibration damping member into the first sink groove is also beneficial to reducing the space occupied by the vibration damping device in the axial direction, which is beneficial to miniaturization of the compressor.

[0039] In some technical solutions, optionally, the cross-sectional shape of the first end of the second vibration damper is a second circular ring, and the cross-sectional shape of the first groove is a first circle; the outer diameter D2 of the second circular ring and the diameter d2 of the first circle satisfy 0.025mm≤d2-D2≤0.07mm.

[0040] In this technical solution, the cross-sectional area of ​​the first end of the second vibration damper is a second annular shape, and specifically, the second vibration damper includes a second spring. The cross-sectional shape of the first sink is a first circle.

[0041] The difference between the outer diameter of the second annular ring and the diameter of the first circle is between 0.025 mm and 0.07 mm. That is, the tolerance range between the maximum diameter of the outer ring of the first end of the second vibration damper and the minimum diameter of the first circle is limited. That is, the difference between the maximum outer contour size of the first end of the second vibration damper and the minimum inner contour size of the first sink is limited.

[0042] In this way, the outer wall of the first end of the second vibration damper can be closely matched with the inner wall of the first sinker, thereby achieving effective fixation between the first end of the second vibration damper and the first bushing, preventing the first end of the second vibration damper from radially moving, and thus achieving effective vibration damping effect of the vibration damping device, thereby effectively attenuating the inertia force and inertia moment of the compressor during operation, reducing the vibration acceleration generated during the operation of the compressor, and thus reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device, and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0043] In some technical schemes, optionally, the second mounting member includes a second bushing and a positioning pin, wherein the second end of the first vibration damper and the second end of the second vibration damper are arranged on the second bushing, the second bushing is provided with a mounting hole, the positioning pin passes through the mounting hole, and is connected to the shell.

[0044] In this technical solution, it is defined that the second mounting member includes a second bushing and a positioning pin. Specifically, the second end of the first vibration damper and the second end of the second vibration damper are arranged on the second bushing, and the second bushing is provided with a mounting hole, the positioning pin passes through the mounting hole, and the positioning pin is connected to the shell, that is, the second bushing is fixed to the shell by the positioning pin.

[0045] That is, by providing the second bushing, the second end of the first vibration damper and the second end of the second vibration damper are indirectly fixed to the shell, so that the second end of the first vibration damper and the second end of the second vibration damper can be effectively fixed while preventing the first vibration damper and the second vibration damper from tilting, thereby effectively avoiding the problem of flutter of the vibration damping assembly itself and increase of low-frequency noise due to the tilt of the first vibration damper or the second vibration damper, ensuring the vibration damping effect of the vibration damping device, and thus improving the noise reduction effect during the operation of the compressor.

[0046] In some technical schemes, optionally, the second bushing includes a second mating surface and a second limiting surface, wherein, along the radial direction of the movement assembly, the second end of the first vibration damper is against the second mating surface, the second limiting surface is connected to the second mating surface, and along the axial direction of the movement assembly, the second end of the first vibration damper is in contact with the second limiting surface.

[0047] In this technical solution, it is defined that the second bushing includes a second matching surface and a second limiting surface. Specifically, the second limiting surface is connected to the second matching surface.

[0048] The second limiting surface and the second matching surface are used to effectively fix the second end of the first vibration damper and the second bushing, thereby improving the installation stability of the second end of the first vibration damper and preventing the second end of the first vibration damper from moving or falling out during the operation of the compressor, thereby achieving an effective vibration damping effect of the vibration damping device, thereby effectively attenuating the inertia force and inertia moment of the compressor during operation, reducing the vibration acceleration generated during the operation of the compressor, and thus reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0049] Specifically, along the radial direction of the movement assembly, the second end of the first vibration damper abuts against the second mating surface, thereby achieving effective radial mating between the second end of the first vibration damper and the second bushing to prevent radial movement of the second end of the first vibration damper.

[0050] Along the axial direction of the movement assembly, the second end of the first vibration damper contacts the second limiting surface, thereby effectively limiting the second end of the first vibration damper in the axial direction, further improving the installation stability of the second end of the first vibration damper, and ensuring the vibration damping effect of the vibration damping device.

[0051] In some technical solutions, optionally, the cross-sectional shape of the second end of the first vibration damper is a third circular ring, and the second mating surface is a second cylindrical surface; the inner diameter d3 of the third circular ring and the diameter of the second cylindrical surface D3 satisfy 0.05mm≤d3-D3≤0.15mm.

[0052] In this technical solution, the cross-sectional shape of the second end of the first vibration damping member is a third circular ring, and specifically, the first vibration damping member includes a first spring. The second matching surface is a second cylindrical surface.

[0053] The difference between the inner diameter of the third annular ring and the diameter of the second cylindrical surface is between 0.05 mm and 0.15 mm. That is, the range of the tolerance between the minimum diameter of the inner ring of the second end of the first vibration damper and the maximum diameter of the second mating surface is limited. That is, the range of the difference between the minimum inner contour size of the second end of the first vibration damper and the maximum outer contour size at the sleeve connection position of the second bushing and the second end of the first vibration damper is limited.

[0054] Thereby, the inner wall of the second end of the first vibration damper can be closely matched with the second mating surface, thereby achieving effective fixation between the second end of the first vibration damper and the second bushing, preventing the second end of the first vibration damper from radial movement, and thus achieving the effective vibration damping effect of the vibration damping device, thereby effectively attenuating the inertia force and inertia moment of the compressor during operation, reducing the vibration acceleration generated when the compressor is running, and thus reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device, and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0055] In some technical solutions, optionally, the second bushing further includes a second recessed groove, the second recessed groove is located radially inward of the second mating surface, and the second end of the second vibration damper is embedded in the second recessed groove and abuts against an inner wall of the second recessed groove.

[0056] In this technical solution, it is defined that the second bushing also includes a second groove. Specifically, along the radial direction of the movement assembly, the second groove is located on the inner side of the second mating surface, and the second end of the second vibration damper is embedded in the second groove, so that the second vibration damper is located inside the first vibration damper. That is to say, the first vibration damper and the second vibration damper are formed in an inside-outside nested form, thereby improving the vibration damping effect of the vibration damping device, further attenuating the inertia force and inertia moment of the compressor during operation, reducing the vibration acceleration generated by the compressor during operation, and thereby reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device, and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0057] In addition, the second end of the second vibration damper abuts against the inner wall of the second groove, thereby achieving effective fixation of the second end of the second vibration damper, improving the installation stability of the second end of the second vibration damper, and preventing the second end of the second vibration damper from moving or falling out during the operation of the compressor, thereby achieving effective vibration reduction effect of the vibration damping device.

[0058] Moreover, embedding the second end of the second vibration damping member into the second sink groove is also beneficial to reducing the space occupied by the vibration damping device in the axial direction, which is beneficial to miniaturization of the compressor.

[0059] In some technical solutions, optionally, the cross-sectional shape of the second end of the second vibration damper is a fourth circular ring, and the cross-sectional shape of the second groove is a second circle; the outer diameter D4 of the fourth circular ring and the diameter d4 of the second circle satisfy 0.025mm≤d4-D4≤0.07mm.

[0060] In this technical solution, the cross-sectional area of ​​the second end of the second vibration damper is a fourth circular ring, and specifically, the second vibration damper includes a second spring. The cross-sectional shape of the second sink is a second circle.

[0061] The difference between the outer diameter of the fourth annular ring and the diameter of the second circle is between 0.025 mm and 0.07 mm. That is, the value range of the tolerance between the maximum diameter of the outer ring of the second end of the second vibration damper and the minimum diameter of the second circle is limited. That is, the value range of the difference between the maximum outer contour size of the second end of the second vibration damper and the minimum inner contour size of the second sink is limited.

[0062] Thereby, the outer wall of the second end of the second vibration damper can be closely matched with the inner wall of the second groove, thereby achieving effective fixation between the second end of the second vibration damper and the second bushing, preventing the second end of the second vibration damper from radially moving, and thus achieving the effective vibration damping effect of the vibration damping device, thereby effectively attenuating the inertia force and inertia moment of the compressor during operation, reducing the vibration acceleration generated during the operation of the compressor, and thus reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device, and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0063] In some technical schemes, optionally, the first shock absorber includes a first spring, the first spring includes a plurality of first elastic parts and a plurality of second elastic parts, along the axial direction of the first spring, the plurality of first elastic parts are located on a side of the plurality of second elastic parts close to the first bushing, and along the radial direction of the first spring, the plurality of first elastic parts are respectively against the first mating surface; wherein, along the axial direction of the first spring, the spacing between two adjacent first elastic parts is smaller than the spacing between two adjacent second elastic parts.

[0064] In this technical solution, the first vibration damping member is defined as a first spring. Specifically, the first spring includes a plurality of first elastic parts and a plurality of second elastic parts, and specifically, the plurality of first elastic parts are located on one side of the plurality of second elastic parts in the axial direction, and the plurality of first elastic parts are against the first mating surface of the first bushing.

[0065] Among the multiple first elastic parts, the spacing between two adjacent first elastic parts is smaller than the spacing between two adjacent second elastic parts among the multiple second elastic parts. That is to say, in the first spring, the dense winding part is sleeved on the first bushing, and the sparse winding part is located between the first bushing and the second bushing for vibration reduction. Thereby, the installation stability of the first end of the first vibration damping member can be further improved, and the first end of the first vibration damping member can be prevented from moving or coming out during the operation of the compressor, thereby achieving the effective vibration reduction effect of the vibration damping device, thereby effectively attenuating the inertial force and inertial moment of the compressor during operation, reducing the vibration acceleration generated during the operation of the compressor, and then reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor having the vibration damping device, and having a significant improvement effect on the sound quality of the refrigeration equipment having the compressor.

[0066] Optionally, the first spring also includes a plurality of third elastic parts, and along the axial direction of the first spring, the plurality of third elastic parts are located on a side of the plurality of second elastic parts close to the second bushing, and along the radial direction of the first spring, the plurality of third elastic parts are respectively against the second mating surface; wherein, along the axial direction of the first spring, the distance between two adjacent third elastic parts is smaller than the distance between two adjacent second elastic parts.

Specifically, the plurality of third elastic parts are located on the other side of the plurality of second elastic parts in the axial direction, and the plurality of third elastic parts are against the second matching surface of the second bushing.

[0068] Among the plurality of third elastic parts, the spacing between two adjacent third elastic parts is smaller than the spacing between two adjacent second elastic parts among the plurality of second elastic parts. That is to say, in the first spring, the dense winding part is sleeved on the second bushing, and the sparse winding part is located between the first bushing and the second bushing for vibration reduction. Thereby, the installation stability of the second end of the first vibration damping member can be further improved, and the second end of the first vibration damping member can be prevented from moving or coming out during the operation of the compressor, thereby achieving the effective vibration reduction effect of the vibration damping device, thereby effectively attenuating the inertial force and inertial moment of the compressor during operation, reducing the vibration acceleration generated during the operation of the compressor, and thereby reducing the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor having the vibration damping device, and having a significant improvement effect on the sound quality of the refrigeration equipment having the compressor.

[0070] Furthermore, the compressor also includes a shell and a core assembly, wherein the shell is connected to the second mounting member, and the core assembly is arranged in the shell and connected to the first mounting member.

[0071] The compressor provided in the embodiment of the present invention comprises a housing, a core assembly and a vibration reduction device, and specifically, the core assembly is located in the housing. It can be understood that the core assembly comprises a pump body and a driving member, and the driving member is connected to the pump body.

[0072] Specifically, when the compressor is repeatedly started and stopped and operates at high load, greater vibrations will be generated, resulting in greater vibration noise from the compressor, affecting the overall quality of the refrigeration equipment having the compressor.

[0073] The first mounting member is connected to the movement assembly, the second mounting member is connected to the shell, at least two vibration damping members are located between the first mounting member and the second mounting member, and at least two vibration damping members are connected to the first mounting member and the second mounting member, that is, the vibration damping assembly is installed on the compressor through the first mounting member and the second mounting member.

[0074] Since the vibration damping assembly includes at least two vibration damping parts, it can effectively attenuate the inertia force and inertia moment of the compressor during operation, reduce the vibration acceleration generated when the compressor is running, and further reduce the vibration noise generated by the compressor during repeated start-stop and high-load operation, thereby improving the reliability of the compressor with the vibration damping device and greatly improving the sound quality of the refrigeration equipment with the compressor.

[0075] In addition, the compressor provided by the above technical solution of the present invention also has the following additional technical features:

[0076] In some technical solutions, optionally, the movement assembly includes a pump body and a driving member, wherein the driving member is connected to the pump body, and the first mounting member is connected to the driving member.

[0077] In this technical solution, it is defined that the core assembly includes a pump body and a driving member. Specifically, the driving member is connected to the pump body. It can be understood that the driving member includes a rotor and a stator, and the pump body includes a crankshaft, a cylinder and a piston. The piston is located in the cylinder, and the crankshaft is connected to the rotor and the piston. Specifically, when the compressor is running, the rotor drives the crankshaft to rotate, and the crankshaft drives the piston to rotate in the cylinder to compress the refrigerant in the cylinder.

[0090] In one embodiment according to the present application, Figure 1 and Figure 2 As shown, a vibration damping device 100 is proposed. The vibration damping device 100 is used for a compressor 300. The compressor 300 includes a shell 310 and a movement assembly 320. The movement assembly 320 is located in the shell 310. The vibration damping device 100 includes: a first mounting member 110, used to connect the movement assembly 320; a second mounting member 120, used to connect the shell 310; a vibration damping assembly 130, the vibration damping assembly 130 includes at least two vibration damping members 131, and the at least two vibration damping members 131 are located between the first mounting member 110 and the second mounting member 120, and are connected to the first mounting member 110 and the second mounting member 120.

[0091] The vibration reduction device 100 provided in the embodiment of the present invention includes a first mounting member 110, a second mounting member 120 and a vibration reduction assembly 130. Specifically, the compressor 300 includes a housing 310 and a core assembly 320, wherein the core assembly 320 is located in the housing 310. It can be understood that the core assembly 320 includes a pump body and a driving member 321, and the driving member 321 is connected to the pump body.

[0092] Specifically, when the compressor 300 is repeatedly started and stopped and operates at a high load, a large vibration will be generated, resulting in a large vibration noise of the compressor 300, which affects the overall quality of the refrigeration equipment having the compressor 300.

[0093] The first mounting member 110 is used to connect the movement assembly 320, the second mounting member 120 is used to connect the shell 310, at least two vibration damping members 131 are located between the first mounting member 110 and the second mounting member 120, and at least two vibration damping members 131 are connected to the first mounting member 110 and the second mounting member 120, that is, the vibration damping assembly 130 is installed on the compressor 300 through the first mounting member 110 and the second mounting member 120.

[0094] Since the vibration damping assembly 130 includes at least two vibration damping members 131, it can effectively attenuate the inertial force and inertial moment of the compressor 300 during operation, reduce the vibration acceleration generated when the compressor 300 is running, and further reduce the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100, and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0095] Optionally, at least one of the at least two vibration dampers 131 is located inside at least one of the other vibration dampers 131. That is, after the at least two vibration dampers 131 are nested inside and outside, they are installed with the first mounting member 110 and the second mounting member 120. This can further improve the vibration damping effect of the vibration damping device 100, and is also beneficial to reducing the occupied space of the vibration damping device 100, and improving the space utilization rate in the housing 310 of the compressor 300.

[0096] Optionally, at least two vibration damping members 131 are arranged adjacent to each other, that is, at least two vibration damping members 131 are arranged side by side, which can also improve the vibration damping effect of the vibration damping device 100. The arrangement can be made according to actual needs.

[0097] Optionally, at least one vibration damper 131 includes a spring or a bellows.

[0098] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the at least two vibration dampers 131 include a first vibration damper 132 and a second vibration damper 133 , and the second vibration damper 133 is located inside the first vibration damper 132 .

[0099] In this embodiment, at least two vibration dampers 131 are defined, including a first vibration damper 132 and a second vibration damper 133. Specifically, the second vibration damper 133 is located inside the first vibration damper 132, that is, the first vibration damper 132 and the second vibration damper 133 are formed in an inner and outer nested form, thereby improving the vibration damping effect of the vibration damping device 100, further attenuating the inertia force and inertia moment of the compressor 300 during operation, reducing the vibration acceleration generated by the compressor 300 during operation, and further reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100, and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0100] At the same time, since the second vibration damping member 133 is located inside the first vibration damping member 132 , it is also beneficial to reduce the space occupied by the vibration damping device 100 in the radial direction, and improve the space utilization rate inside the casing 310 of the compressor 300 .

[0101] Optionally, the first vibration damper 132 includes a first spring, and the second vibration damper 133 includes a second spring 135. The first spring and the second spring 135 are formed into an inner and outer nested structure, which can improve the overall stiffness of the first spring and the second spring 135, thereby improving the vibration damping effect of the vibration damping device 100, and achieving effective suppression of vibrations generated during the operation of the compressor 300.

[0102] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the first mounting member 110 includes a first bushing 111 and a fastener 112, wherein the first end of the first vibration damper 132 and the first end of the second vibration damper 133 are disposed on the first bushing 111, the fastener 112 is disposed on a side of the first bushing 111 away from the second mounting member 120, and the first bushing 111 is connected to the movement assembly 320 via the fastener 112.

[0103] In this embodiment, it is defined that the first mounting member 110 includes a first bushing 111 and a fastener 112. Specifically, the first end of the first vibration damper 132 and the first end of the second vibration damper 133 are disposed on the first bushing 111, and the fastener 112 is disposed on a side of the first bushing 111 away from the second mounting member 120, that is, the fastener 112 is located on a side of the first bushing 111 close to the movement assembly 320. The first bushing 111 is fixed to the movement assembly 320 by the fastener 112.

[0104] The vibration reduction system in the related art adopts an Archimedes seat spring, and the Archimedes seat spring is directly fixed to the bottom of the motor stator through a stator screw. The other end of the seat spring is a through hole, which is installed on the seat spring bushing of the lower housing, and the seat spring bushing is fixed to the lower housing through a positioning pin. Since the seat spring is directly fixed to the bottom of the stator through the stator screw, it is easy to cause the seat spring to tilt, which is easy to cause the seat spring itself to vibrate and cause low-frequency noise.

[0105] The installation of the first bushing 111 and the core assembly 320 is achieved by the fastener 112. That is to say, by setting the first bushing 111, the first end of the first vibration damper 132 and the first end of the second vibration damper 133 are indirectly fixed to the core assembly 320, so that the first end of the first vibration damper 132 and the first end of the second vibration damper 133 can be effectively fixed while preventing the first vibration damper 132 and the second vibration damper 133 from tilting, thereby effectively avoiding the vibration of the vibration damping assembly 130 itself and the increase of low-frequency noise due to the tilt of the first vibration damper 132 or the second vibration damper 133, thereby ensuring the vibration reduction effect of the vibration damping device 100, and thereby improving the noise reduction effect during the operation of the compressor 300.

[0106] Optionally, fastener 112 comprises a screw.

[0107] like Figure 1 As shown, in some embodiments, optionally, the first bushing 111 includes a first mating surface 113 and a first limiting surface 114, wherein, along the radial direction of the movement assembly 320, the first end of the first vibration damper 132 is against the first mating surface 113, and the first limiting surface 114 is connected to the first mating surface 113, and along the axial direction of the movement assembly 320, the first end of the first vibration damper 132 is in contact with the first limiting surface 114.

[0108] In this embodiment, it is defined that the first bushing 111 includes a first matching surface 113 and a first limiting surface 114 . Specifically, the first limiting surface 114 is connected to the first matching surface 113 .

[0109] The first limiting surface 114 and the first matching surface 113 are used to effectively fix the first end of the first vibration damper 132 to the first bushing 111, thereby improving the installation stability of the first end of the first vibration damper 132 and preventing the first end of the first vibration damper 132 from moving or falling out during the operation of the compressor 300, thereby achieving an effective vibration damping effect of the vibration damping device 100, thereby effectively attenuating the inertial force and inertial moment of the compressor 300 during operation, reducing the vibration acceleration generated by the compressor 300 during operation, and thereby reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100 and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0110] Specifically, along the radial direction of the movement assembly 320, the first end of the first vibration damper 132 abuts against the first mating surface 113, thereby achieving effective cooperation between the first end of the first vibration damper 132 and the first bushing 111 in the radial direction and preventing the first end of the first vibration damper 132 from moving in the radial direction.

[0111] Along the axial direction of the movement assembly 320, the first end of the first vibration damper 132 contacts the first limiting surface 114, thereby effectively limiting the first end of the first vibration damper 132 in the axial direction, further improving the installation stability of the first end of the first vibration damper 132, and ensuring the vibration damping effect of the vibration damping device 100.

[0112] like Figure 1 As shown, in some embodiments, optionally, the cross-sectional shape of the first end of the first vibration damper 132 is a first circular ring, and the first mating surface 113 is a first cylindrical surface; the inner diameter d1 of the first circular ring and the diameter of the first cylindrical surface D1 satisfy 0.05mm≤d1-D1≤0.15mm.

[0113] In this embodiment, the cross-sectional shape of the first end of the first vibration damper 132 is a first annular shape. Specifically, the first vibration damper 132 includes a first spring. The first matching surface 113 is a first cylindrical surface.

[0114] The difference between the inner diameter of the first annular shape and the diameter of the first cylindrical surface is between 0.05 mm and 0.15 mm. That is, the tolerance range between the minimum diameter of the inner ring of the first end of the first vibration damper 132 and the maximum diameter of the first mating surface 113 is defined. That is, the difference between the minimum inner contour size of the first end of the first vibration damper 132 and the maximum outer contour size at the sleeve connection position of the first bushing 111 and the first end of the first vibration damper 132 is defined.

[0115] Thereby, the inner wall of the first end of the first vibration damper 132 can be tightly matched with the first mating surface 113, thereby achieving effective fixation between the first end of the first vibration damper 132 and the first bushing 111, preventing the first end of the first vibration damper 132 from radial movement, and thus achieving an effective vibration damping effect of the vibration damping device 100, thereby effectively attenuating the inertia force and inertia moment of the compressor 300 during operation, reducing the vibration acceleration generated by the compressor 300 during operation, and thus reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100, and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0116] like Figure 1 As shown, in some embodiments, optionally, the first bushing 111 also includes a first groove 115, which is located radially inward of the first mating surface 113, and the first end of the second vibration damper 133 is embedded in the first groove 115 and abuts against the inner wall of the first groove 115.

[0117] In this embodiment, it is defined that the first bushing 111 also includes a first groove 115. Specifically, along the radial direction of the movement assembly 320, the first groove 115 is located on the inner side of the first mating surface 113, and the first end of the second vibration damper 133 is embedded in the first groove 115, so that the second vibration damper 133 is located inside the first vibration damper 132. In other words, the first vibration damper 132 and the second vibration damper 133 are formed in an inside-outside nested form, thereby improving the vibration damping effect of the vibration damping device 100, further attenuating the inertia force and inertia moment of the compressor 300 during operation, reducing the vibration acceleration generated by the compressor 300 during operation, and thereby reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100, and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0118] In addition, the first end of the second vibration damper 133 abuts against the inner wall of the first sink groove 115, thereby achieving effective fixation of the first end of the second vibration damper 133, improving the installation stability of the first end of the second vibration damper 133, and preventing the first end of the second vibration damper 133 from moving or falling out during the operation of the compressor 300, thereby achieving effective vibration reduction effect of the vibration damping device 100.

[0119] Moreover, embedding the first end of the second vibration damping member 133 into the first sinking groove 115 is also beneficial to reducing the space occupied by the vibration damping device 100 in the axial direction, which is beneficial to miniaturizing the compressor 300.

[0120] like Figure 1 As shown, in some embodiments, optionally, the cross-sectional shape of the first end of the second vibration damper 133 is a second circular ring, and the cross-sectional shape of the first sink 115 is a first circle; the outer diameter D2 of the second circular ring and the diameter d2 of the first circle satisfy 0.025mm≤d2-D2≤0.07mm.

[0121] In this embodiment, the cross-sectional area of ​​the first end of the second vibration damper 133 is a second annular shape. Specifically, the second vibration damper 133 includes a second spring 135. The cross-sectional shape of the first sink 115 is a first circle.

[0122] The difference between the outer diameter of the second annular shape and the diameter of the first circle is between 0.025 mm and 0.07 mm. That is, the tolerance range between the maximum diameter of the outer ring of the first end of the second vibration damper 133 and the minimum diameter of the first circle is limited. That is, the difference between the maximum outer contour size of the first end of the second vibration damper 133 and the minimum inner contour size of the first sink 115 is limited.

[0123] Thereby, the outer wall of the first end of the second vibration damper 133 can be closely matched with the inner wall of the first sink groove 115, so as to realize the effective fixation between the first end of the second vibration damper 133 and the first bushing 111, and prevent the first end of the second vibration damper 133 from radial movement, thereby realizing the effective vibration damping effect of the vibration damping device 100, thereby effectively attenuating the inertia force and inertia moment of the compressor 300 during operation, reducing the vibration acceleration generated by the compressor 300 during operation, and thus reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100, and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0124] like Figure 1 and Figure 2As shown, in some embodiments, optionally, the second mounting member 120 includes a second bushing 121 and a positioning pin, wherein the second end of the first vibration damper 132 and the second end of the second vibration damper 133 are disposed on the second bushing 121, the second bushing 121 is provided with a mounting hole 126, the positioning pin passes through the mounting hole 126, and is connected to the shell 310.

[0125] In this embodiment, it is defined that the second mounting member 120 includes a second bushing 121 and a positioning pin. Specifically, the second end of the first vibration damper 132 and the second end of the second vibration damper 133 are arranged on the second bushing 121, and the second bushing 121 is provided with a mounting hole 126, the positioning pin passes through the mounting hole 126, and the positioning pin is connected to the shell 310, that is, the second bushing 121 is fixed to the shell 310 by the positioning pin.

[0126] That is, by providing the second bushing 121, the second end of the first vibration damper 132 and the second end of the second vibration damper 133 are indirectly fixed to the shell 310, so that the second end of the first vibration damper 132 and the second end of the second vibration damper 133 can be effectively fixed while preventing the first vibration damper 132 and the second vibration damper 133 from tilting, thereby effectively avoiding the vibration of the vibration damping assembly 130 itself and the increase of low-frequency noise due to the tilt of the first vibration damper 132 or the second vibration damper 133, ensuring the vibration damping effect of the vibration damping device 100, and thereby improving the noise reduction effect during the operation of the compressor 300.

[0127] like Figure 1 As shown, in some embodiments, optionally, the second bushing 121 includes a second mating surface 123 and a second limiting surface 124, wherein, along the radial direction of the movement assembly 320, the second end of the first vibration damper 132 is abutted against the second mating surface 123, and the second limiting surface 124 is connected to the second mating surface 123, and along the axial direction of the movement assembly 320, the second end of the first vibration damper 132 is in contact with the second limiting surface 124.

[0128] In this embodiment, it is defined that the second bushing 121 includes a second matching surface 123 and a second limiting surface 124 . Specifically, the second limiting surface 124 is connected to the second matching surface 123 .

[0129] The second limiting surface 124 and the second matching surface 123 are used to effectively fix the second end of the first vibration damper 132 to the second bushing 121, thereby improving the installation stability of the second end of the first vibration damper 132 and preventing the second end of the first vibration damper 132 from moving or falling out during the operation of the compressor 300, thereby achieving an effective vibration damping effect of the vibration damping device 100, thereby effectively attenuating the inertial force and inertial moment of the compressor 300 during operation, reducing the vibration acceleration generated by the compressor 300 during operation, and thereby reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100 and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0130] Specifically, along the radial direction of the movement assembly 320, the second end of the first vibration damper 132 abuts against the second mating surface 123, thereby achieving effective radial mating between the second end of the first vibration damper 132 and the second bushing 121, preventing the second end of the first vibration damper 132 from moving in the radial direction.

[0131] Along the axial direction of the movement assembly 320, the second end of the first vibration damper 132 contacts the second limiting surface 124, thereby effectively limiting the second end of the first vibration damper 132 in the axial direction, further improving the installation stability of the second end of the first vibration damper 132, and ensuring the vibration damping effect of the vibration damping device 100.

[0132] like Figure 1 As shown, in some embodiments, optionally, the cross-sectional shape of the second end of the first vibration damper 132 is a third circular ring, and the second mating surface 123 is a second cylindrical surface; the inner diameter d3 of the third circular ring and the diameter of the second cylindrical surface D3 satisfy 0.05mm≤d3-D3≤0.15mm.

[0133] In this embodiment, the cross-sectional shape of the second end of the first vibration damper 132 is a third annular shape, and specifically, the first vibration damper 132 includes a first spring. The second matching surface 123 is a second cylindrical surface.

[0134] The difference between the inner diameter of the third annular ring and the diameter of the second cylindrical surface is between 0.05 mm and 0.15 mm, which defines the range of the tolerance between the minimum diameter of the inner ring of the second end of the first vibration damper 132 and the maximum diameter of the second mating surface 123. This also defines the range of the difference between the minimum inner contour size of the second end of the first vibration damper 132 and the maximum outer contour size at the sleeve connection position of the second bushing 121 and the second end of the first vibration damper 132.

[0135] Thereby, the inner wall of the second end of the first vibration damper 132 can be tightly matched with the second mating surface 123, thereby achieving effective fixation between the second end of the first vibration damper 132 and the second bushing 121, preventing the second end of the first vibration damper 132 from radial movement, and thus achieving the effective vibration damping effect of the vibration damping device 100, thereby effectively attenuating the inertia force and inertia moment of the compressor 300 during operation, reducing the vibration acceleration generated by the compressor 300 during operation, and thus reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100, and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0136] like Figure 1 As shown, in some embodiments, optionally, the second bushing 121 also includes a second groove 125, which is located radially inward of the second mating surface 123, and the second end of the second vibration damper 133 is embedded in the second groove 125 and abuts against the inner wall of the second groove 125.

[0137] In this embodiment, it is defined that the second bushing 121 also includes a second groove 125. Specifically, along the radial direction of the movement assembly 320, the second groove 125 is located on the inner side of the second mating surface 123, and the second end of the second vibration damper 133 is embedded in the second groove 125, so that the second vibration damper 133 is located inside the first vibration damper 132. In other words, the first vibration damper 132 and the second vibration damper 133 are formed in an inside-outside nested form, thereby improving the vibration damping effect of the vibration damping device 100, further attenuating the inertia force and inertia moment of the compressor 300 during operation, reducing the vibration acceleration generated by the compressor 300 during operation, and thereby reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100, and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0138] In addition, the second end of the second vibration damper 133 abuts against the inner wall of the second groove 125, thereby achieving effective fixation of the second end of the second vibration damper 133, improving the installation stability of the second end of the second vibration damper 133, and preventing the second end of the second vibration damper 133 from moving or falling out during the operation of the compressor 300, thereby achieving effective vibration reduction effect of the vibration damping device 100.

[0139] Moreover, embedding the second end of the second vibration damping member 133 into the second sink groove 125 is also beneficial to reducing the space occupied by the vibration damping device 100 in the axial direction, which is beneficial to miniaturizing the compressor 300.

[0140] like Figure 1As shown, in some embodiments, optionally, the cross-sectional shape of the second end of the second shock absorber 133 is a fourth circular ring shape, and the cross-sectional shape of the second sink 125 is a second circular shape; between the outer diameter D4 of the fourth circular ring shape and the diameter d4 of the second circular shape, 0.025 mm ≤ d4 - D4 ≤ 0.07 mm is satisfied.

[0141] In this embodiment, the cross-sectional area of the second end of the second shock absorber 133 is a fourth circular ring shape. Specifically, the second shock absorber 133 includes a second spring 135. The cross-sectional shape of the second sink 125 is a second circular shape.

[0142] The difference between the outer diameter of the fourth circular ring shape and the diameter of the second circular shape is between 0.025 mm and 0.07 mm. That is, the value range of the tolerance between the maximum diameter of the outer ring of the second end of the second shock absorber 133 and the minimum diameter of the second circular shape is defined. That is, the value range of the difference between the maximum outer contour dimension of the second end of the second shock absorber 133 and the minimum inner contour dimension of the second sink 125 is defined.

[0143] Thereby, the outer wall of the second end of the second shock absorber 133 can be closely fitted with the inner wall of the second sink 125, realizing the effective fixation between the second end of the second shock absorber 133 and the second bushing 121, preventing the second end of the second shock absorber 133 from moving radially, and further realizing the effective shock absorption effect of the shock absorption device 100, thereby effectively attenuating the inertial force and inertial moment during the operation of the compressor 300, reducing the vibration acceleration generated during the operation of the compressor 300, and further reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, improving the reliability of the compressor 300 with the shock absorption device 100, and having a great improvement effect on the sound quality of the refrigeration equipment with the compressor 300.

[0144] As Figure 1 As shown, in some embodiments, optionally, the first shock absorber 132 includes a first spring 134. The first spring 134 includes a plurality of first elastic parts 140 and a plurality of second elastic parts 150. Along the axial direction of the first spring 134, the plurality of first elastic parts 140 are located on the side of the plurality of second elastic parts 150 close to the first bushing 111. Along the radial direction of the first spring 134, the plurality of first elastic parts 140 are respectively abutted against the first mating surface 113; wherein, along the axial direction of the first spring 134, the distance between two adjacent first elastic parts 140 is less than the distance between two adjacent second elastic parts 150.

[0145] In this embodiment, the first vibration damper 132 is defined as a first spring 134. Specifically, the first spring 134 includes a plurality of first elastic parts 140 and a plurality of second elastic parts 150. Specifically, the plurality of first elastic parts 140 are located on one side of the plurality of second elastic parts 150 in the axial direction, and the plurality of first elastic parts 140 abut against the first mating surface 113 of the first bushing 111.

[0146] Among the plurality of first elastic parts 140, the spacing between two adjacent first elastic parts 140 is smaller than the spacing between two adjacent second elastic parts 150 among the plurality of second elastic parts 150. That is to say, in the first spring 134, the dense winding part is sleeved on the first bushing 111, and the sparse winding part is located between the first bushing 111 and the second bushing 121 for vibration reduction. Thus, the installation stability of the first end of the first vibration reduction member 132 can be further improved, and the first end of the first vibration reduction member 132 can be prevented from moving or coming out during the operation of the compressor 300, thereby achieving the effective vibration reduction effect of the vibration reduction device 100, thereby effectively attenuating the inertial force and inertial moment of the compressor 300 during operation, reducing the vibration acceleration generated when the compressor 300 is running, and then reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, improving the reliability of the compressor 300 having the vibration reduction device 100, and having a significant improvement effect on the sound quality of the refrigeration equipment having the compressor 300.

[0147] Optionally, the first spring 134 also includes a plurality of third elastic portions 160. Along the axial direction of the first spring 134, the plurality of third elastic portions 160 are located on one side of the plurality of second elastic portions 150 close to the second bushing 121. Along the radial direction of the first spring 134, the plurality of third elastic portions 160 are respectively abutted against the second mating surface 123. Wherein, along the axial direction of the first spring 134, the spacing between two adjacent third elastic portions 160 is smaller than the spacing between two adjacent second elastic portions 150.

[0148] Specifically, the first spring 134 further includes a plurality of third elastic portions 160 . Specifically, the plurality of third elastic portions 160 are located at the other side of the plurality of second elastic portions 150 in the axial direction, and the plurality of third elastic portions 160 abut against the second mating surface 123 of the second bushing 121 .

[0149] Among the plurality of third elastic parts 160, the spacing between two adjacent third elastic parts 160 is smaller than the spacing between two adjacent second elastic parts 150 among the plurality of second elastic parts 150. That is to say, in the first spring 134, the dense winding part is sleeved on the second bushing 121, and the sparse winding part is located between the first bushing 111 and the second bushing 121 for vibration reduction. Thus, the installation stability of the second end of the first vibration reduction member 132 can be further improved, and the second end of the first vibration reduction member 132 can be prevented from moving or coming out during the operation of the compressor 300, thereby achieving the effective vibration reduction effect of the vibration reduction device 100, thereby effectively attenuating the reciprocating inertia force and reciprocating inertia moment of the compressor 300 during operation, reducing the vibration acceleration generated when the compressor 300 is running, thereby reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, improving the reliability of the compressor 300 having the vibration reduction device 100, and having a significant improvement effect on the sound quality of the refrigeration equipment having the compressor 300.

[0150] It can be understood that, along the axial direction of the first spring 134 , the height of the first mating surface 113 and the second mating surface 123 is related to the length of the closely wound portion of the first spring 134 .

[0151] Optionally, the second vibration damper 133 includes a second spring 135, and the second spring 135 includes a dense winding part and a sparse winding part, wherein the dense winding part of the second spring 135 is respectively against the inner wall of the first sink 115 and the inner wall of the second sink 125, and the sparse winding part is located between the first bushing 111 and the second bushing 121 for vibration reduction. Thus, the installation stability of the two ends of the second vibration damper 133 can be further improved, and the two ends of the second vibration damper 133 can be prevented from moving or coming out during the operation of the compressor 300, thereby achieving an effective vibration reduction effect of the vibration damping device 100, thereby effectively attenuating the reciprocating inertia force and reciprocating inertia moment of the compressor 300 during operation, reducing the vibration acceleration generated by the compressor 300 during operation, thereby reducing the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, improving the reliability of the compressor 300 having the vibration damping device 100, and having a significant improvement effect on the sound quality of the refrigeration equipment having the compressor 300.

[0152] According to a second aspect of the present invention, a compressor 300 is provided, comprising a vibration reduction device 100 as provided in any of the above embodiments, and thus having all the beneficial technical effects of the vibration reduction device 100, which will not be described in detail herein.

[0153] like Figure 1 and Figure 2As shown, further, the compressor 300 also includes a shell 310 and a core assembly 320 , wherein the shell 310 is connected to the second mounting member 120 , and the core assembly 320 is disposed in the shell 310 and connected to the first mounting member 110 .

[0154] The compressor 300 provided in the embodiment of the present invention comprises a housing 310, a core assembly 320 and a vibration reduction device 100. Specifically, the core assembly 320 is located in the housing 310. It can be understood that the core assembly 320 comprises a pump body and a driving member 321, and the driving member 321 is connected to the pump body.

[0155] Specifically, when the compressor 300 is repeatedly started and stopped and operates at a high load, a large vibration will be generated, resulting in a large vibration noise of the compressor 300, which affects the overall quality of the refrigeration equipment having the compressor 300.

[0156] The first mounting member 110 is connected to the movement assembly 320, the second mounting member 120 is connected to the shell 310, at least two vibration damping members 131 are located between the first mounting member 110 and the second mounting member 120, and at least two vibration damping members 131 are connected to the first mounting member 110 and the second mounting member 120, that is, the vibration damping assembly 130 is installed on the compressor 300 through the first mounting member 110 and the second mounting member 120.

[0157] Since the vibration damping assembly 130 includes at least two vibration damping members 131, it can effectively attenuate the inertial force and inertial moment of the compressor 300 during operation, reduce the vibration acceleration generated when the compressor 300 is running, and further reduce the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100, and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0158] Optionally, the compressor 300 comprises a reciprocating compressor.

[0159] like Figure 2 As shown, in some embodiments, optionally, the movement assembly 320 includes a pump body and a driving member 321 , wherein the driving member 321 is connected to the pump body, and the first mounting member 110 is connected to the driving member 321 .

[0160] In this embodiment, it is defined that the core assembly 320 includes a pump body and a driving member 321. Specifically, the driving member 321 is connected to the pump body. It can be understood that the driving member 321 includes a rotor and a stator, and the pump body includes a crankshaft, a cylinder and a piston. The piston is located in the cylinder, and the crankshaft is connected to the rotor and the piston. Specifically, when the compressor 300 is running, the rotor drives the crankshaft to rotate, and the crankshaft drives the piston to rotate in the cylinder to compress the refrigerant in the cylinder.

[0161] The first mounting member 110 is connected to the driving member 321, that is, one end of the vibration reduction assembly 130 is fixed to the driving member 321, and the other end is fixed to the shell 310, so as to attenuate the inertia force and inertia moment of the compressor 300 during operation, reduce the vibration acceleration generated when the compressor 300 is running, and further reduce the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration reduction device 100, and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0162] Optionally, the first mounting member 110 is connected to the stator, that is, one end of the vibration reduction assembly 130 is fixed to the stator, and the other end is fixed to the housing 310 .

[0163] According to a third aspect of the present invention, there is provided a refrigeration device, comprising a compressor 300 as provided in any of the above embodiments, and thus having all the beneficial technical effects of the compressor 300, which will not be described in detail herein.

[0164] It is understandable that when the compressor 300 is repeatedly started and stopped and operates at a high load, greater vibrations will be generated, resulting in greater vibration noise of the compressor 300, affecting the overall quality of the refrigeration equipment having the compressor 300.

[0165] Specifically, the vibration reduction device 100 includes a first mounting member 110, a second mounting member 120 and a vibration reduction assembly 130. Specifically, the compressor 300 includes a housing 310 and a core assembly 320, wherein the core assembly 320 is located in the housing 310. It can be understood that the core assembly 320 includes a pump body and a driving member 321, and the driving member 321 is connected to the pump body.

[0166] The first mounting member 110 is used to connect the movement assembly 320, the second mounting member 120 is used to connect the shell 310, at least two vibration damping members 131 are located between the first mounting member 110 and the second mounting member 120, and at least two vibration damping members 131 are connected to the first mounting member 110 and the second mounting member 120, that is, the vibration damping assembly 130 is installed on the compressor 300 through the first mounting member 110 and the second mounting member 120.

[0167] Since the vibration damping assembly 130 includes at least two vibration damping members 131, it can effectively attenuate the inertial force and inertial moment of the compressor 300 during operation, reduce the vibration acceleration generated when the compressor 300 is running, and further reduce the vibration noise generated by the compressor 300 during repeated start-stop and high-load operation, thereby improving the reliability of the compressor 300 having the vibration damping device 100, and greatly improving the sound quality of the refrigeration equipment having the compressor 300.

[0168] Optionally, at least one of the at least two vibration dampers 131 is located inside at least one of the other vibration dampers 131. That is, after the at least two vibration dampers 131 are nested inside and outside, they are installed with the first mounting member 110 and the second mounting member 120. This can further improve the vibration damping effect of the vibration damping device 100, and is also beneficial to reducing the occupied space of the vibration damping device 100, and improving the space utilization rate in the housing 310 of the compressor 300.

[0169] Optionally, the refrigeration device includes a refrigerator or an air conditioner.
