Description

Technical Field

[0001] This application relates to the field of household appliances, and more particularly to a limiting vibration damping device, a compressor unit, and an air conditioner. Background Technology

[0002] In air conditioning equipment, the compressor serves as both the core driving force and a source of vibration affecting its normal operation. The sources of vibration experienced by the compressor in air conditioning equipment are complex, primarily including: vibration generated by the compressor itself during operation; vibration transmitted from the compressor to connected components, causing resonance between adjacent components and the compressor; and vibration from the compressor's operating environment. To reduce compressor operating noise and extend its service life, vibration damping devices must be installed on the compressor.

[0003] In related technologies, compressor vibration reduction is generally achieved by setting vibration damping springs or vibration damping rubber. However, vibration damping springs / rubber can only provide a single vibration reduction effect, resulting in poor overall vibration reduction effect and high operating noise of the compressor.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0050] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0051] See Figures 1 to 7In one aspect, embodiments of this application provide a limiting and vibration damping device, which includes: a first housing 100, a second housing 200, a first elastic element 300, a second elastic element 400, a bidirectional limiting structure 500, and a first locking element 600.

[0052] The first housing 100 has a first opening;

[0053] The second housing 200 has a second opening, and the second opening end of the second housing 200 is inserted into the first housing 100 through the first opening;

[0054] The first elastic element 300 is disposed inside the first housing 100 and extends toward the first opening;

[0055] The second elastic member 400 is disposed within the second housing 200 and extends toward the second opening;

[0056] A bidirectional limiting structure 500 is disposed between the first elastic member 300 and the second elastic member 400; and

[0057] A first locking member 600 is provided on the second housing 200. The first locking member 600 is used to lock the second housing 200 and the first housing 100 in the insertion direction of the second housing 200 and the first housing 100.

[0058] In this embodiment, by optimizing the specific structure of the limiting vibration damping device 50, the vibration caused by the rigid connection between vibration source devices (such as compressors) and the coupling effect of complex excitation between vibration source devices (such as compressors) is weakened, and the operating noise of the compressor is greatly reduced.

[0059] Specifically, the limiting vibration damping device 50 is configured as a combination component comprising at least a first housing 100, a second housing 200, a first elastic element 300, a second elastic element 400, a bidirectional limiting structure 500, and a first locking element 600. The first housing 100 is connected to a first vibration source device (such as a compressor), and the second housing 200 is connected to a second vibration source device (such as a compressor). At least a portion of the second housing 200 is embedded within the first housing 100. The first elastic element 300, the bidirectional limiting structure 500, and the second elastic element 400 are disposed inside the first housing 100 and the second housing 200 to buffer and lower the first housing in the insertion direction of the second housing 200 and the first housing 100. The vibration force from the vibration source device (such as a compressor) received by the second housing 200 and / or the first housing 100 reduces / weakens the vibration amplitude of the vibration source device (such as a compressor) at least in the insertion direction of the second housing 200 and the first housing 100, buffers the vibration of the dual vibration source device (dual compressor) system in the insertion direction of the second housing 200 and the first housing 100, and improves the vibration reduction effect of the vibration source device (such as a compressor); the first locking member 600 is used to lock the second housing 200 and the first housing 100 in the insertion direction of the second housing 200 and the first housing 100 to prevent the limiting vibration damping device 50 from coming apart or from shifting or misaligning due to vibration, thereby reducing the vibration reduction effect of the limiting vibration damping device 50.

[0060] In one example, the first housing 100 is a square outer shell with a first opening. The second housing 200 is a square inner shell with a second opening. The second opening is positioned opposite to the first opening, and the size of the first opening is slightly larger than the size of the second opening, so that at least a portion of the second housing 200 can be inserted into the first housing 100 from the first opening, thus achieving the insertion of the second housing 200 into the first housing 100. When the second housing 200 and the first housing 100 are inserted into place, they are locked by the first locking member 600, limiting the maximum limit position of the second housing 200 and the first housing 100; at this time, the relative position of the second housing 200 and the first housing 200 in their insertion direction can be adjusted at least by the first elastic member 300, the bidirectional limiting structure 500, and the second elastic member 400.

[0061] In one example, the first housing 100 includes an outer rectangular connecting plate and an outer rectangular connecting frame. The outer rectangular connecting frame has a through insertion channel, and one end of the outer rectangular connecting frame is connected to the outer rectangular connecting plate. The outer rectangular connecting plate is larger than the outer rectangular connecting frame, and the outer rectangular connecting plate has connecting holes for engaging with fasteners such as bolts / screws to connect the first housing 100 to a compressor. The second housing 200 includes an inner rectangular connecting plate and an inner rectangular connecting frame. The inner rectangular connecting frame has a through receiving channel, and one end of the inner rectangular connecting frame is connected to the inner rectangular connecting plate. The inner rectangular connecting plate is larger than the inner rectangular connecting frame, and the inner rectangular connecting plate has connecting holes for engaging with fasteners such as bolts / screws to connect the first housing 100 to another compressor. The inner rectangular connecting plate has the same size as the outer connecting plate, and the inner rectangular connecting frame has a smaller size than the outer rectangular connecting frame. One end of the first locking member 600 is disposed on the inner rectangular connecting plate, and the other end protrudes from the outer rectangular connecting plate.

[0062] In one example, the stiffness values ​​of the first elastic element 300 and the second elastic element 400 range from 170 N / m to 200 N / m. For example, but not limited to, the first elastic element 300 and the second elastic element 400 are high-stiffness helical springs. The first elastic element 300 and the second elastic element 400 provide the limiting vibration damping device 50 with an elastic buffering force along the insertion direction between the second housing 200 and the first housing 100, reducing vibration propagation in that direction.

[0063] See Figures 1 to 3 In one possible implementation, the bidirectional limiting structure 500 includes a limiting member 510, two third elastic members 520 and two first elastic bodies 530. The two third elastic members 520 are respectively disposed on opposite sides of the limiting member 510, and one first elastic body 530 is disposed corresponding to one third elastic member 520. The first elastic body 530 is connected to the limiting member 510 through the third elastic member 520.

[0064] In this embodiment, the specific configuration of the bidirectional limiting structure 500 is optimized. Specifically, the bidirectional limiting structure 500 is configured as a combination component including at least a limiting member 510, two third elastic members 520, and two first elastic bodies 530. The first elastic body 530, the third elastic member 520, the limiting member 510, the other third elastic member 520, and the other first elastic body 530 are arranged sequentially along the insertion direction of the second housing 200 and the first housing 100 to provide elastic buffering force to the compressor in the insertion direction.

[0065] In one example, the stiffness of the third elastic element 520 ranges from 100 N / m to 130 N / m. For example, but not limited to, the third elastic element 520 is a low-stiffness helical spring.

[0066] In one example, the first projectile 530 is made of rubber. The first projectile 530 is a frustum-shaped structure similar to a lampshade, with a groove at the large-diameter end and a closed small-diameter end. A third elastic element 520 is located inside the first projectile 530, with one end abutting against the inner wall of the small rounded end of the first projectile 530, and the other end connected to the limiting element 510. The open end of the first projectile 530 abuts against the limiting element 510.

[0067] See Figures 1 to 3 In one possible implementation, the bidirectional limiting structure 500 further includes two second projectiles 540, one second projectile 540 corresponding to one first projectile 530, and the second projectile 540 is located on the side of the first projectile 530 away from the third elastic member 520.

[0068] In this embodiment, the specific configuration of the bidirectional limiting structure 500 is further optimized. Specifically, the bidirectional limiting structure 500 is configured as a combination component including at least a limiting member 510, two third elastic members 520, two first elastic bodies 530, and two second elastic bodies 540. The two second elastic bodies 540 are respectively disposed on the side of the two first elastic bodies 530 away from the third elastic members 520, so as to connect with the first elastic members 300 and the second elastic members 400.

[0069] In one example, the second elastic body 540 is a circular gasket structure such as a rubber gasket / stainless steel gasket, which has a certain rigidity. Thus, when the first elastic element 300 and the second elastic element 400 abut against the second elastic body 540, the vibration force received by the first elastic element 300 and the second elastic element 400 can be effectively transmitted to the first elastic body 530 and the third elastic element 520, and finally to the limiting element 510, where the limiting element 510 cancels out and weakens the vibration force in both directions.

[0070] See Figures 1 to 3 In one possible implementation, the limiting member 510 includes a limiting block 511 and two limiting posts 512, with the two limiting posts 512 respectively disposed on opposite sides of the limiting block 511, and a third elastic member 520 disposed on the side of the limiting post 512 away from the limiting block 511.

[0071] In this embodiment, the specific configuration of the limiting member 510 is optimized. Specifically, the limiting member 510 is configured as a combination component including at least a limiting block 511 and two limiting posts 512. The limiting block 511 has groove structures on its opposite two sides, and the two limiting posts 512 are respectively disposed in the corresponding groove structures. A limiting connection hole is provided on the side of the limiting post 512 away from the limiting block 511. The limiting connection hole extends along the axial direction of the limiting post 512. One end of the third elastic member 520 is inserted into the limiting connection hole, and the other end abuts against the inner wall of the first elastic body 530. In this way, the vibration energy on both sides of the bidirectional limiting structure 500 is finally transferred to the limiting block 511 and absorbed by the limiting block 511, effectively reducing the resonance between the compressors on the left and right sides; at the same time, it effectively alleviates the low-frequency vibration noise generated by the rigid connection between the two compressors.

[0072] In one example, eight third elastic elements 520 are configured, and one limiting post 512 is provided with four limiting connection holes, and one limiting connection hole is provided with one third elastic element 520 inserted.

[0073] See Figure 1 and Figure 2 In one possible implementation, the second housing 200 is provided with a plurality of first limiting holes 201, and the limiting block 511 is provided with a plurality of second limiting holes 501. The second limiting holes 501 are arranged opposite to the first limiting holes 201. The bidirectional limiting structure 500 also includes a second locking member 550, which is sequentially inserted into the first limiting holes 201 and the second limiting holes 501 to connect and fasten the second housing 200 and the limiting block 511.

[0074] In this embodiment, the specific configuration of the bidirectional limiting structure 500 is further optimized. Specifically, the bidirectional limiting structure 500 is configured as a combination of at least a limiting member 510, two third elastic members 520, two first elastic bodies 530, and a second locking member 550. The limiting member 510 is configured as a combination of at least a limiting block 511 and two limiting posts 512. The limiting block 511 is connected and fastened to the second housing 200 through the second locking member 550.

[0075] In one possible implementation, a plurality of first limiting holes 201 are spaced apart along the insertion direction of the second housing 200 and the first housing 100, and a plurality of second limiting holes 501 are spaced apart along the insertion direction of the second housing 200 and the first housing 100.

[0076] In this embodiment, a plurality of first limiting holes 201 provided on the second housing 200 are spaced apart along the insertion direction of the second housing 200 and the first housing 100. Similarly, a plurality of second limiting holes 501 provided on the limiting block 511 are spaced apart along the insertion direction of the second housing 200 and the first housing 100. Thus, by adjusting the positions of the first limiting holes 201 and the second limiting holes 501 into which the second locking member 550 is actually inserted, the connection position of the limiting block 511 within the second housing 200 can be adjusted. This allows for position adjustment of the bidirectional limiting structure 500 in the insertion direction between the second housing 200 and the first housing 100, enabling the limiting and vibration damping device 50 to adapt to the limiting and vibration damping of various compressors.

[0077] In one example, the bidirectional limiting structure 500 can adjust its installation position according to the weight of the compressor. For example, when the compressor weighs between 0 kg and 20 kg, the second locking member 550 can be inserted into the first limiting hole 201 furthest from the second opening on the second housing 200 and the second limiting hole 501 closest to the second opening on the limiting block 511, so that the limiting vibration damping device 50 is subjected to a smaller buffering elastic force; when the compressor weighs between 20 kg and 30 kg, the second locking member 550 can be inserted into the first limiting hole 201 in the middle on the second housing 200 and the second limiting hole 501 in the middle on the limiting block 511, so that the limiting vibration damping device 50 is subjected to a moderate buffering elastic force; when the compressor weighs more than 30 kg, the second locking member 550 can be inserted into the first limiting hole 201 closest to the second opening on the second housing 200 and the second limiting hole 501 furthest from the second opening on the limiting block 511, so that the limiting vibration damping device 50 is subjected to a larger buffering elastic force.

[0078] In one example, the second locking element 550 can be a bolt / screw or other similar component, but is not limited thereto. To improve the tightness of the connection between the bidirectional limiting structure 500 and the second housing 200, multiple second locking elements 550 can be provided as needed.

[0079] See Figure 1 In one possible implementation, the limiting and damping device 50 further includes a first buffer 710 and a second buffer 720, wherein the first buffer 710 is disposed between the first housing 100 and the first elastic member 300, and the second buffer 720 is disposed between the second housing 200 and the second elastic member 400.

[0080] In this embodiment, the specific configuration of the limiting vibration damping device 50 is further optimized. Specifically, the limiting vibration damping device 50 is configured as a combination of at least a first housing 100, a second housing 200, a first elastic element 300, a second elastic element 400, a bidirectional limiting structure 500, a first locking element 600, a first buffer element 710, and a second buffer element 720. The first buffer element 710 is connected to the inner wall of the end of the first housing 100 away from the first opening, and the second buffer element 720 is connected to the inner wall of the end of the second housing 200 away from the second opening. In this way, the first buffer element 710 / second buffer element 720 can absorb part of the vibration energy, then compress the first elastic element 300 / second elastic element 400, and finally compress the bidirectional limiting structure 500. At this time, the first elastic element 300 / second elastic element 400 and the bidirectional limiting structure 500 undergo elastic deformation, absorbing the vibration energy generated by the left and right compressors and reducing vibration. For example, but not limited to, the first buffer 710 is a buffer plate, and the second buffer 720 is a buffer plate.

[0081] See Figure 1 In one possible implementation, the vibration damping device further includes a first limiting post 730 and a second limiting post 740. The first limiting post 730 is disposed on the side of the first buffer member 710 facing the second buffer member 720, and the second limiting post 740 is disposed on the side of the second buffer member 720 facing the first buffer member 710. One end of the first elastic member 300 is sleeved on the first limiting post 730, and the other end is connected to the side of the bidirectional limiting structure 500 facing the first housing 100. One end of the second elastic member 400 is sleeved on the second limiting post 740, and the other end is connected to the side of the bidirectional limiting structure 500 facing the second housing 200.

[0082] In this embodiment, the specific configuration of the limiting vibration damping device 50 is further optimized. Specifically, the limiting vibration damping device 50 is configured as a combination of at least a first housing 100, a second housing 200, a first elastic member 300, a second elastic member 400, a bidirectional limiting structure 500, a first locking member 600, a first buffer member 710, a second buffer member 720, a first limiting post 730, and a second limiting post 740. The first limiting post 730 is connected to the side of the first buffer member 710 facing the first opening and is used to limit the position of the first elastic member 300. The second limiting post 740 is connected to the side of the second buffer member 720 facing the second opening and is used to limit the position of the second elastic member 400.

[0083] In one example, the first locking member 600 passes sequentially through the second buffer member 720, the second limiting post 740, the second elastic member 400, the bidirectional limiting structure 500, the first elastic member 300, the first limiting post 730, and the first buffer member 710, and finally exits the first housing 100.

[0084] See Figure 1 and Figure 6 In one possible implementation, the second housing 200 includes a housing body and a plurality of partitions. The housing body has a receiving cavity. The plurality of partitions are intersected within the housing body to divide the receiving cavity into a plurality of independent chambers. A plurality of bidirectional limiting structures 500 are provided, and a plurality of second elastic members 400 are provided. A second elastic member 400 and a bidirectional limiting structure 500 are correspondingly provided in the same independent chamber.

[0085] In this embodiment, the specific configuration of the second housing 200 is optimized. Specifically, the second housing 200 is configured as a combination component including at least a housing body and multiple partitions. The multiple partitions are arranged in a matrix staggered arrangement within the housing body, dividing the accommodating cavity within the housing body into multiple independent chambers. Each independent chamber can accommodate a second elastic element 400 and a bidirectional limiting structure 500. In this way, the multiple partitions reduce interference during the operation of the multiple bidirectional limiting structures 500, thereby improving the operational stability of the multiple bidirectional limiting structures 500.

[0086] In one example, multiple second buffers 720 are configured, with one second buffer 720 corresponding to one independent chamber.

[0087] See Figure 1 , Figure 4 and Figure 6 In one possible implementation, the limiting and damping device 50 further includes a fourth elastic component 800 disposed between the second housing 200 and the first housing 100.

[0088] In this embodiment, the specific configuration of the limiting vibration damping device 50 is further optimized. Specifically, the limiting vibration damping device 50 is configured as a combination of at least a first housing 100, a second housing 200, a first elastic element 300, a second elastic element 400, a bidirectional limiting structure 500, a first locking element 600, and a fourth elastic component 800. The fourth elastic component 800 is disposed between the first housing 100 and the second housing 200 to absorb a small amount of longitudinal and vertical vibration energy of the compressor in the first housing 100 and the second housing 200, thereby reducing the longitudinal and vertical coupling effect of the dual compressor system components.

[0089] See Figure 1 and Figure 4In one possible implementation, the fourth elastic component 800 includes a fourth elastic element 810, at least two fifth elastic elements 820, a first connector 830, and a second connector 840. The first connector 830 is connected to the outside of the second housing 200, and the second connector 840 is connected to the inside of the first housing 100. The fourth elastic element 810 is connected to the first connector 830 through the fifth elastic elements 820, and the fourth elastic element 810 is connected to the second connector 840 through the fifth elastic elements 820.

[0090] In this embodiment, the specific configuration of the fourth elastic component 800 is optimized. Specifically, the fourth elastic component 800 is configured as a combination of at least four elastic elements, at least two fifth elastic elements 820, a first connector 830, and a second connector 840. The fourth elastic element 810 can provide elastic buffering force in a direction that is perpendicular to both the side wall of the second housing 200 and the side wall of the first housing 100, so as to reduce / reduce the vibration caused by the compressor at least in the longitudinal direction of the first housing 100 and the second housing 200 (in this case, the fourth elastic element 810 is disposed between the top inner wall of the first housing 100 and the top outer wall of the second housing 200, and / or the fourth elastic element 810 is disposed between the bottom inner wall of the first housing 100 and the top outer wall of the second housing 200) and / or, in the vertical direction of the first housing 100 and the second housing 200 (in this case, the fourth elastic element 810 is disposed between the front inner wall of the first housing 100 and the front outer wall of the second housing 200, and / or the fourth elastic element 810 is disposed between the rear inner wall of the first housing 100 and the rear outer wall of the second housing 200). The first connector 830 can be fastened to the outer wall of the second housing 200 using bolts, screws, or other fasteners. The second connector 840 can be fastened to the inner wall of the first housing 100 using bolts, screws, or other fasteners. The fourth elastic member 810 is provided with a connection and fixing hole for the insertion of the fifth elastic member 820, and the other end of the fifth elastic member 820 is connected to the first connector 830 / second connector 840. In this way, the fourth elastic member 810 can provide a larger elastic buffering force, while the fifth elastic member 820 can provide a smaller elastic buffering force.

[0091] In one example, the fourth elastic element 810 is an S-shaped leaf spring, the fifth elastic element 820 is a soft spring, the first connecting element 830 is a connecting pressure plate, and the second connecting element 840 is a connecting pressure plate.

[0092] See Figure 1 and Figure 4 In one possible implementation, a plurality of fourth elastic components 800 are provided, and the plurality of fourth elastic components 800 are arranged axially at intervals around the outer periphery of the second housing 200 with the insertion direction of the second housing 200 and the first housing 100 as the reference.

[0093] In this embodiment, the specific configuration of the fourth elastic component 800 is optimized. Specifically, to improve the vibration damping effect of the limiting vibration damping device 50 in multiple directions, multiple fourth elastic components 800 are configured. The multiple fourth elastic components 800 are configured on the top, bottom, front, and rear sides of the first housing 100 and the second housing 200 to at least reduce / weaken the vibration energy of the two compressors in the longitudinal and vertical directions.

[0094] See Figure 1 and Figure 3 In one possible implementation, the first elastic member 300 is provided with a first through hole, the bidirectional limiting structure 500 is provided with a second through hole, the second elastic member 400 is provided with a third through hole, and the end of the first housing 100 away from the first opening is provided with a fourth through hole. The first locking member 600 passes through the first through hole, the second through hole, the third through hole and the fourth through hole in sequence to connect and fasten the second housing 200 and the first housing 100.

[0095] In this embodiment, the connection method of the first locking member 600 is optimized. Specifically, the first locking member 600 is used to connect and secure the second housing 200, the first elastic member 300, the bidirectional limiting structure 500, the second elastic member 400, and the first housing 100 through a plug-in connection. At the same time, the first locking member 600 also limits the position of the first elastic member 300, the bidirectional limiting structure 500, and the second elastic member 400, preventing them from moving or misaligning radially.

[0096] In one example, the first locking member 600 includes a stud and a nut. One end of the stud is disposed on the second housing 200, and the other end passes through the side of the first housing 100 away from the first opening, and cooperates with the nut located outside the first housing 100 to lock the second housing 200 and the first housing 100 in the insertion direction of the second housing 200 and the first housing 100.

[0097] In one example, to improve the tightness of the connection between the second housing 200 and the first housing 100, multiple studs and multiple nuts are provided, with at least one nut corresponding to each stud. For example, but not limited to, there are four studs and four nuts. The four studs are rectangularly distributed inside the second housing 200, and the four nuts are rectangularly distributed outside the first housing 100.

[0098] See Figure 3 , Figure 5 and Figure 6 In one possible implementation, in the insertion direction of the second housing 200 and the first housing 100, the ratio of the length L of the bidirectional limiting structure 500 to the length L1 of the limiting and damping device 50 is 0.45 to 0.55; and / or,

[0099] In the horizontal and vertical directions of the insertion direction between the second housing 200 and the first housing 100, the ratio of the width D of the bidirectional limiting structure 500 to the width D1 of the limiting and damping device 50 is 0.30 to 0.35; and / or,

[0100] The ratio of the height H1 of the limiting vibration damping device 50 to the width D1 of the limiting vibration damping device 50 is 1 to 1.3.

[0101] In this embodiment, in order to ensure that the elastic buffer force provided by the limiting vibration damping device 50 to the compressor is moderate, the dimensions of the length L of the bidirectional limiting structure 500 and the length L1 of the limiting vibration damping device 50, the width D of the bidirectional limiting structure 500 and the width D1 of the limiting vibration damping device 50, and the height H1 of the limiting vibration damping device 50 and the width D1 of the limiting vibration damping device 50 are optimized. If the ratio between the length L of the bidirectional limiting structure 500 and the length L1 of the limiting vibration damping device 50 is less than 0.45, the ratio between the width D of the bidirectional limiting structure 500 and the width D1 of the limiting vibration damping device 50 is less than 0.3, and the ratio between the height H1 of the limiting vibration damping device 50 and the width D1 of the limiting vibration damping device 50 is less than 1, the elasticity of the limiting vibration damping device 50 will be too small, and it will not be able to achieve a good vibration damping function. If the ratio between the length L of the bidirectional limiting structure 500 and the length L1 of the limiting vibration damping device 50 is greater than 0.55, the ratio between the width D of the bidirectional limiting structure 500 and the width D1 of the limiting vibration damping device 50 is greater than 0.35, and the ratio between the height H1 of the limiting vibration damping device 50 and the width D1 of the limiting vibration damping device 50 is greater than 1.3, the elasticity of the limiting vibration damping device 50 will be too large, resulting in a large lateral displacement of the compressor cylinder, which will not meet the requirements of the dual compressor system to resist environmental vibration.

[0102] See Figure 7 Secondly, embodiments of this application also provide a compressor unit, including a first compressor 10, a second compressor 20 spaced apart from the first compressor 10, a first mounting connection assembly 30 connected to the first compressor 10, a second mounting connection assembly 40 connected to the second compressor 20, and a limiting vibration damping device 50 as described above, wherein the limiting vibration damping device 50 is connected between the first mounting connection assembly 30 and the second mounting connection assembly 40.

[0103] In this embodiment, to reduce the vibration generated by the two compressors in the dual compressor system, a limiting vibration damping device 50 is configured between the two compressors. The limiting vibration damping device 50 reduces / weakens the vibration generated by the dual compressors in at least three dimensions: the insertion direction of the second housing 200 and the first housing 100 of the limiting vibration damping device 50, the height direction of the compressor (i.e., the longitudinal direction of the second housing 200 and the first housing 100), and the radial direction of the compressor (i.e., the vertical direction of the second housing 200 and the first housing 100). This reduces the operating noise of the compressor unit and improves the service life of the compressor unit.

[0104] Furthermore, the specific structure of the limiting vibration damping device 50 is as described in the above embodiments. Since this compressor unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here.

[0105] In one possible implementation, the ratio of the length L1 of the limiting vibration damping device 50 to the height of the compressor is 0.2 to 0.3. The ratio of the width D1 of the limiting vibration damping device 50 to the diameter of the compressor barrel is 0.4 to 0.5. Wherein, the length L1 of the limiting vibration damping device 50 is the maximum length of the assembled limiting vibration damping device 50 in the insertion direction between the second housing 200 and the first housing 100; the height of the compressor is the maximum height of the compressor in the longitudinal direction between the second housing 200 and the first housing 100. Wherein, the width D1 of the limiting vibration damping device 50 is the maximum width of the assembled limiting vibration damping device 50 in the vertical direction between the second housing 200 and the first housing 100; the diameter of the compressor barrel is the maximum radial value of the compressor in the vertical direction between the second housing 200 and the first housing 100.

[0106] In this embodiment, to ensure that the elastic buffering force provided by the limiting vibration damping device 50 to the dual compressor system is moderate, the dimensions of the length L1 of the limiting vibration damping device 50 and the height of the compressor, and the width D1 of the limiting vibration damping device 50 and the diameter of the compressor cylinder are optimized. If the ratio between the length L1 of the limiting vibration damping device 50 and the height of the compressor is less than 0.2, and the ratio between the width D1 of the limiting vibration damping device 50 and the diameter of the compressor cylinder is less than 0.4, the elasticity of the limiting vibration damping device 50 will be too small, and it will not be able to achieve a good vibration damping function. If the ratio between the length L1 of the limiting vibration damping device 50 and the height of the compressor is greater than 0.3, and the ratio between the width D1 of the limiting vibration damping device 50 and the diameter of the compressor cylinder is greater than 0.5, the elasticity of the limiting vibration damping device 50 will be too large, resulting in a large lateral displacement of the compressor cylinder, which will not meet the requirements of the dual compressor system's ability to resist environmental vibration.

The specific structure of the compressor unit is as described in the above embodiments.
