Description

Technical Field

[0001] This invention belongs to the field of compressor technology, specifically relating to a vibration damping device and an air conditioner. Background Technology

[0002] Vibration and noise are two main indicators for evaluating the performance of air conditioner outdoor units. Generally speaking, the vibration sources inside an air conditioner outdoor unit are the compressor and the fan. Among them, the rotary compressor, as the core power source, generates relatively strong mechanical vibrations during high-speed rotation due to its inherent structural imbalance, making it the most significant vibration source in the outdoor unit. To reduce the vibration impact of the rotary compressor during operation, most current designs use rubber pads to separate the rotary compressor from the chassis, thereby reducing the transmission of vibration between the rotary compressor and the chassis. However, in actual use, a single rubber pad can only reduce the vibration transmission at certain frequencies during the operation of the rotary compressor, primarily reducing the vertical vibration. For variable frequency rotary compressors, which have a wide operating frequency range, the rotary compressor generates significant vibrations in the vertical, horizontal, and circumferential directions. Therefore, a single rubber pad structure cannot meet the vibration reduction requirements under all operating conditions, and a structure that can significantly reduce the vibration generated by the variable frequency rotary compressor unit during operation needs to be considered.

[0003] The related technology discloses a compressor vibration damping device. Its advantage is that the distance between the pad and the base plate where the stiffness support is located can be adjusted to change the compression state of the vibration damping support. Its disadvantage is that an additional pad structure is required, and when the compressor generates torsional force, the position of the vibration damping support needs to be adjusted multiple times to suppress the horizontal sway of the compressor, which is not convenient to use.

[0004] Because existing vibration damping devices cannot meet the requirements for multi-directional vibration reduction, resulting in poor vibration reduction effect and other technical problems, this invention studies and designs a vibration damping device and an air conditioner.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0039] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0040] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0041] See also Figure 1-12As shown in the embodiment of the present invention, a vibration damping device is provided, comprising: a first baffle 12 and a second baffle 9. The first baffle 12 is used to receive vibrations from the compressor. A plurality of spring plate units and a plurality of elastic units 10 are disposed between the first baffle 12 and the second baffle 9. The two ends of the spring plate units are respectively connected to the first baffle 12 and the second baffle 9. One end of the elastic unit 10 is connected to the first baffle 12 and the other end is connected to the second baffle 9. The elastic unit 10 corresponds one-to-one with the spring plate unit. In this technical solution, when the compressor generates a vertical force, the first baffle 12 receives the vibration of the compressor, and the spring plate unit receives a downward vertical force, causing the spring plate unit to deform and absorb vibration energy. When the compressor generates horizontal and circumferential forces, the first baffle 12 moves, causing the elastic unit 10 to deform and absorb vibration energy. Through the spring plate units and the elastic units 10, the multi-directional vibrations generated during compressor operation can be effectively damped, ensuring the operating stability of the compressor.

[0042] In some embodiments, the elastic unit 10 includes a first elastic element 25, a second elastic element 28, and an elastic frame 27. The first elastic element 25 is connected to the first baffle 12, and the second elastic element 28 is connected to the second baffle 9. The elastic frame 27 has a first end and a second end. The first end is connected to the first elastic element 25, and the second end is connected to the second elastic element 28. A plurality of third elastic elements 26 are disposed between the inner walls of the two sides of the elastic frame 27. In this technical solution, the vibration damping device also includes a housing 4, which is tubular. The first baffle 12 and the second baffle 9 are both located inside the housing 4. A fifth elastic element 8 is sleeved on the outer peripheral wall of the first baffle 12. The fifth elastic element 8 is a rubber ring. The fifth elastic element 8 is fixed to the inner wall of the housing 4 and the outer peripheral wall of the first baffle 12 by vulcanization. When the compressor generates horizontal and circumferential vibrations, the fifth elastic element 8 can also absorb part of the horizontal and circumferential vibration energy, achieving a vibration damping effect. The elastic frame 27 is a rectangular frame made of rubber. 25. The second elastic element 28 and the third elastic element 26 are springs. Positioning holes are provided on the first baffle 12 and the second baffle 9. The first elastic element 25 and the second elastic element 28 are connected to the positioning holes of the first baffle 12 and the second baffle 9, respectively. When the compressor vibrates horizontally and circumferentially, the first elastic element 25 and the second elastic element 28 exert tension on both ends of the elastic frame 27, causing deformation along the length of the elastic frame 27, i.e., reducing its width. The third elastic element 26 is compressed internally on both sides of the elastic frame 27, and the third elastic element 26 absorbs vibration energy. Specifically, when the compressor vibrates circumferentially and horizontally, it is transmitted to the first baffle 12. The first elastic element 25 is driven by the first baffle 12, and the second elastic element 28 is pulled by force on the rubber elastic frame 27. Consequently, the elastic frame 27 and the third elastic element 26 undergo compression deformation, absorbing horizontal vibration energy and achieving vibration reduction effects in both the circumferential and horizontal directions.

[0043] In some embodiments, the elastic unit 10 is located outside the spring plate unit in a radially outward direction along the first baffle 12, and the elastic frame 27 is at least partially connected to the spring plate unit. In this technical solution, the middle part of the elastic frame 27 is connected to the spring plate unit through a vulcanization process. The spring plate unit fixes and limits the elastic frame 27 without affecting the deformation of the elastic frame 27 in the length direction, so that the elastic frame 27 can absorb horizontal vibration energy and partially absorb the energy generated by vertical vibration. The vulcanization process refers to the technology of bonding rubber to metal.

[0044] In some embodiments, the spring plate unit includes a first leaf spring plate 13 and a second leaf spring plate 14. The ends of the first leaf spring plate 13 and the second leaf spring plate 14 are staggered. The two ends of the first leaf spring plate 13 are respectively connected to the first baffle 12 and the second baffle 9, and the two ends of the second leaf spring plate 14 are respectively connected to the first baffle 12 and the second baffle 9. In this technical solution, the ends of the first leaf spring plate 13 and the second leaf spring plate 14 are staggered, and the first leaf spring plate 13 and the second leaf spring plate 14 are arc-shaped. When the first baffle 12 receives vertical vibration, it compresses the first leaf spring plate 13 and the second leaf spring plate 14 downward, making the first leaf spring plate 13 and the second leaf spring plate 14 more curved, so that the first leaf spring plate 13 and the second leaf spring plate 14 absorb vibration energy.

[0045] In some embodiments, the spring plate unit further includes a first support rod 15 and a second support rod 21. Both the first support rod 15 and the second support rod 21 are provided with a first sleeve 17. The end of the first support rod 15 facing away from the second support rod 21 and the end of the second support rod 21 facing away from the first support rod 15 are both provided with a first fixing member 16. The first support rod 15 and the second support rod 21 are connected by an adjustment unit. The ends of the first leaf spring plate 13 and the ends of the second leaf spring plate 14 are staggered through the first sleeve 17. In this technical solution, the axial direction of the first sleeve 17 is perpendicular to the axial direction of the first support rod 15 and the second support rod 21. The first support rod 15 and the second support rod 21 pass through the first sleeve 17. Second grooves are formed at both ends of the first sleeve 17. The ends of the first leaf spring plate 13 and the second leaf spring plate 14 are respectively connected to the first baffle 12 and the second baffle 9. Third grooves are provided on both the first leaf spring plate 13 and the second leaf spring plate 14. The third grooves and the second grooves interlock, so that the ends of the first leaf spring plate 13 and the ends of the second leaf spring plate 14 are staggered through the first sleeve 17. The arrangement of the first leaf spring plate 13 and the second leaf spring plate 14 enhances their support effect on the first baffle 12 and the second baffle 9. When the first leaf spring plate 13 and the second leaf spring plate 14 deform, the first sleeve 17 slides on the first support rod 15 and the second support rod 21. The two ends of the first leaf spring plate 13 and the two ends of the second leaf spring plate 14 are staggered through the first sleeve 17, similar in structure to [other configuration]. Grooves are formed on the side walls of both the first leaf spring plate 13 and the second leaf spring plate 14, and the two grooves interlock to form a cross arrangement, which improves both the performance and support effect of the first leaf spring plate 13 and the second leaf spring plate 14. The first fixing member 16 limits the first sleeve 17. At least part of the first leaf spring plate 13 and the second leaf spring plate 14 extend out of the first sleeve 17, and the upper and lower extended portions of the first leaf spring plate 13 and the second leaf spring plate 14 are welded to the discs of the first baffle 12 and the second baffle 9. The first fixing member 16 uses a nut and is threadedly connected to the first support rod 15 and the second support rod 21. The first fixing member 16 is used for the first sleeve 17. The height of the ends of the first support rod 15 and the second support rod 21 facing away from each other is less than the height of the farthest ends of the first leaf spring plate 13 and the second leaf spring plate 14, that is, there is a gap between the first support rod 15 and the first baffle 12, and between the second support rod 21 and the second baffle 9.

[0046] In some embodiments, the spring plate unit further includes a third spring plate 45, the two ends of which are connected to the first support rod 15 and the second support rod 21, respectively. The end of the third spring plate 45 is located between the first sleeve 17 and the first fixing member 16. In this technical solution, bolt holes are provided at both ends of the third spring plate 45, which are then fitted onto the support rod 15 and the second support rod 21 through the bolt holes. The third spring plate 45 can improve the vibration damping effect of the spring plate unit in the vertical direction.

[0047] In some embodiments, both the first support rod 15 and the second support rod 21 are provided with limiting portions, which are located between the first sleeve 17 and the adjusting unit. Both the first support rod 15 and the second support rod 21 are provided with a fourth elastic element 18, which is located between the first sleeve 17 and the limiting portion. In this technical solution, the fourth elastic element 18, which is a spring, compresses the fourth elastic element 18 when the first sleeve 17 moves along the first support rod 15 and the second support rod 21, thereby improving the vibration damping effect of the spring plate unit. The limiting portion is an annular protrusion structure that limits the fourth elastic element 18.

[0048] In some embodiments, the adjustment unit includes a first link 20, a second link 22, a third link 23, and a fourth link 24. The first link 20, the second link 22, the third link 23, and the fourth link 24 are sequentially and movably connected. The connection between the first link 20 and the second link 22 is located on the first support rod 15, and the connection between the third link 23 and the fourth link 24 is located on the second support rod 21. The connection between the first link 20 and the fourth link 24 is connected to the first leaf spring plate 13, and the connection between the second link 22 and the third link 23 is connected to the second leaf spring plate 14. In this technical solution, the first connecting rod 20, the second connecting rod 22, the third connecting rod 23, and the fourth connecting rod 24 are sequentially and movably connected to form a rhomboid structure. The connection points of the first connecting rod 20 and the fourth connecting rod 24, and the second connecting rod 22 and the third connecting rod 23, are connected by connecting balls. Each connecting ball has a ball seat, which is welded to the second leaf spring plate 14 and the first leaf spring plate 13. The ball seat has a groove, and the ball is located within the groove. The connection points of the first connecting rod 20 and the fourth connecting rod 24, and the second connecting rod 22 and the third connecting rod 23, are connected to the ball. Both the end of the first support rod 15 facing the second support rod 21 and the end of the second support rod 21 facing the first support rod 15 are provided with... The connector 19 is bolted, and threaded holes are provided on the first support rod 15 and the second support rod 21. One connector 19 passes through the first connecting rod 20, the threaded hole and the second connecting rod 22 in sequence, and the other connector 19 passes through the third connecting rod 23, the threaded hole and the fourth connecting rod 24 in sequence. When the rotor compressor transmits vibration downward, the first baffle 12 compresses the plate spring damping unit, and the fourth elastic element 18 is compressed by force, which drives the first support rod 15 to move downward. The downward force is transformed into a force along the two sides of the rhombus. The first connecting rod 20, the second connecting rod 22, the third connecting rod 23 and the fourth connecting rod 24 separate the second plate spring plate 14 and the first plate spring plate 13, providing a vibration damping effect. The second support rod 21 operates on the same principle as the first support rod 15. Therefore, the leaf spring damping unit moves up and down through the first support rod 15 and the second support rod 21, which in turn opens the first connecting rod 20, the second connecting rod 22, the third connecting rod 23 and the fourth connecting rod 24 on both sides, causing the second leaf spring plate 14 and the first leaf spring plate 13 to deform and counteract the vibration from the compressor, thus achieving the vibration absorption effect.

[0049] In some embodiments, the vibration damping device includes a first part 5, a second part 6, and a third part 7. The first part 5 is disposed on the side of the first baffle 12 facing away from the second baffle 9, and the third part 7 is disposed on the side of the second baffle 9 facing away from the first baffle 12. The second part 6 is located between the first baffle 12 and the second baffle 9. In this technical solution, both the second part 6 and the third part 7 are located within the housing. Through the first part 5, the second part 6, and the third part 7, the multi-stage vibration damping effect of the vibration damping device is further improved.

[0050] In some embodiments, the first part 5 includes a sixth elastic element 29. Along the axial direction of the sixth elastic element 29, its outer peripheral wall is provided with multiple grooves that penetrate the sixth elastic element 29. The first baffle 12 is provided with multiple protrusions 30, each corresponding to one of the grooves, and each protrusion 30 is at least partially located within the groove. In this technical solution, the sixth elastic element 29 uses rubber pads, and the multiple grooves are evenly arranged along the axial direction of the sixth elastic element 29. When the compressor vibrates, the sixth elastic element 29 absorbs some of the vibration energy. The protrusions 30 in the first baffle 12 can suppress the vibration of the sixth elastic element 29 and transfer excess vibration energy to the second part 6. The protrusions 30 are for better transmission of vibration to the lower components. Since the protrusions 30 are distributed circumferentially, and a leaf spring damping component is provided below the protrusions 30, the vertical and circumferential forces generated by the compressor will be preferentially transmitted to the area below the limiting plate, causing the leaf spring to operate and achieving a damping effect.

[0051] In some embodiments, the second part includes a central column 31 that passes through the first part, the first baffle 12, and the second baffle 9. A second sleeve 11 is fitted onto the central column 31 and is located between the first baffle 12 and the second baffle 9. The second sleeve 11 has a third end and a fourth end. A closure member 33 is provided on the third end to close the gap between the third end and the central column 31. A seventh elastic member 32 is provided on the central column 31 and is located between the first baffle 12 and the closure member 33. The fourth end abuts against the second baffle 9. A plurality of metal balls 44 are present in the gap between the second sleeve 11 and the central column 31. In this technical solution, the central column 31 is located at the center of the first baffle 9. There are at least three spring plate units, which are welded at a certain angle around the central column 31 along the circumferential direction to the first baffle 12 and the second baffle 9. The seventh elastic element 32 is a spring. All elastic elements in this invention can be springs. The second sleeve 11 and the central column 31 are coaxial but have different radii; the radius of the second sleeve 11 is larger than the radius of the central column 31. A metal ball 44 can be placed in the gap between them. When the metal particles are subjected to external vibration, they will generate random collision motion, canceling out the generated energy. The metal ball 44 can also be made of other materials; any small ball made of a material that can cancel out the generated energy is acceptable. The sealing element 33 is a nut. One end of the seventh elastic element 32 is connected to the first baffle 12, and the other end is connected to the sealing element 33. The sealing element 33 is used to seal the gap between the central column 31 and the second sleeve 11. The sealing element 33 is positioned below the weld between the leaf spring and the baffle for limiting its position. The second sleeve 11 and the second baffle 9 are an integral structure. The second baffle 9 is used for welding the leaf spring vibration damping unit. When the rotor compressor generates circumferential vibration, the vibration is transmitted downwards through the central column 31 and the first baffle 12. The metal ball 44 located between the central column 31 and the second sleeve 11 is affected by the vibration and undergoes random collision motion within the sleeve. Relative movement occurs between the central column 31 and the second sleeve 11. The first baffle 12 compresses the seventh elastic element 32, causing the second sleeve 11 to move relative to the central column 31. This can dissipate some of the vibration energy. The first baffle 12 drives the first elastic element 25 and the second elastic element 28, and the spring is stressed, generating resistance in the opposite direction of vibration, thus counteracting the effects of vibration. Furthermore, the leaf spring vibration damping unit is arranged circumferentially, and circumferential vibration will cause the leaf spring to be compressed, achieving a circumferential vibration damping effect.

[0052] In some embodiments, the third part includes a cover 34 and a chassis 38, with the central column 31 penetrating the cover 34. The cover 34 covers the chassis 38, and the cover 34 and the chassis 38 enclose a cavity structure. An annular baffle is provided on the inner bottom surface of the chassis 38, dividing the cavity structure into a first chamber and a second chamber. The second chamber is located outside the first chamber, and the end of the central column 31 is located inside the first chamber. An eighth elastic element 37 is provided, one end of which is connected to the central column 31, and the other end is connected to a mass block 36. The mass block 36 is fitted inside the annular baffle, and two positioning elements 35 are provided inside the annular baffle. The mass block 36 is located between the two positioning elements 35, and the mass block 36 divides the first chamber into a third chamber 42 and a fourth chamber 43. Along the axial direction of the annular baffle, the mass block 36 is provided with multiple through holes 41. The third chamber 42 contains damping fluid. In this technical solution, one end of the eighth elastic element 37 is welded to the lower end of the central column 31, and the other end is connected to the mass block 36. The mass block 36 can be made of hard rubber or metal. The positioning elements 35 are rubber rings, which are installed inside the annular baffle and fixed to the inner wall of the annular baffle by vulcanization. The mass block 36 is located between the two positioning elements 35, and the mass block 36 has through holes 41 for the damping fluid to flow up and down. The cover 34 is made of rubber. The third chamber 42 between the mass block 36 and the bottom surface of the chassis 38 contains damping fluid, with the immersion height slightly higher than that of the mass block 36. When vibration is transmitted and causes the damping device below, the eighth elastic element 37 at the lower end of the central column 31 compresses the mass block 36, and the mass block 36 squeezes the positioning element 35. The positioning element 35 undergoes elastic deformation, and the space of the third chamber 42 at the lower end of the positioning element 35 is compressed and reduced. Since the amount of damping fluid is slightly higher than that of the mass block 134, the damping fluid will flow upward through the through hole 41 on the mass block 36. The damping fluid absorbs vibration energy and achieves the vibration reduction effect.

[0053] In some embodiments, a plurality of third baffles 39 are provided in the second chamber, the third baffles 39 extending radially along the annular baffle, and the plurality of third baffles 39 divide the second chamber into a plurality of fifth chambers, each fifth chamber containing a damping ball 40. In this technical solution, after the positioning member 35 undergoes elastic deformation, a portion of the vibration energy is transferred to the chassis 38 through the annular baffle. At this time, the damping ball 40 in the chassis 38 undergoes random collision motion under vibration, consuming the downwardly transmitted vibration energy and achieving a vibration absorption effect.

[0054] This invention provides a vibration damping device that addresses the multi-directional vibrations generated during the operation of a rotary compressor. It overcomes the limitations of existing single-rubber pad vibration damping structures, which cannot effectively reduce multi-directional vibration displacement and absorb vibration energy, leading to excessive vibration transmitted to the compressor base plate. Existing structures cannot adapt to the forces generated by compressor vibration to achieve a proper vibration damping effect.

[0055] The vibration reduction device of this invention employs a multi-stage vibration reduction and limiting device to adapt to the generated impact force and adjust to the optimal vibration reduction state under different operating conditions. Through the interlocking of plate springs, helical springs, discs, diamond structures, metal particles, and damping vibration reduction devices, the vibration energy transmitted from the compressor to the base plate is significantly reduced, weakening the vibration displacement generated during compressor operation.

[0056] In the vibration reduction device of this invention, the leaf spring vibration reduction unit works when the rotor compressor generates vertical and circumferential vibrations. The internal rhomboid structure opens up the deformation of the leaf spring, thereby absorbing vibration energy and achieving vertical and circumferential vibration reduction effects.

[0057] This invention relates to a vibration damping device, specifically a lower damping vibration damping device. When the rigid central rod transmits compressor vibration to the lower mass block, the mass block compresses the positioning rubber ring, causing elastic deformation of the positioning rubber ring. The mass block is partially immersed in damping fluid, and has through holes for the damping fluid to flow vertically. When the positioning rubber ring undergoes elastic deformation, the damping fluid also flows vertically under force, absorbing vibration energy and achieving a vibration damping effect. Furthermore, the vibration of the mass block causes the damping particles to move randomly, thereby dissipating the vibration energy generated by the compressor.

[0058] The present invention also provides an air conditioner including the vibration damping device 3 described above.

[0059] The air conditioner of the present invention also includes a compressor 1, which includes a lug 2. The vibration damping device 3 of the present invention is installed at the lug 2. Specifically, the central column 31 and the lug 2 can be connected by threads, and the first part abuts against the lug 2.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention.
