Description

Technical Field

[0001] The present invention relates to the field of compressors, and in particular to a vibration reduction support structure and a compressor system comprising the same. Background Art

[0002] The vibration reduction support structure of the existing compressor usually includes a plurality of rubber pads 2, such as Figure 1 The rubber foot pad 2 and the compressor foot 11 of the compressor 1 are fixedly connected to the unit bottom plate 3 through bolts 41, nuts 42 and flat washers 22. Figure 2 . In this structure, high requirements are placed on the bolt position, size, bolt verticality, position and size of the mounting hole of the compressor foot 11, etc. If these dimensions deviate, after the compressor is installed, the radial clearance between the inner diameter of the rubber foot pad and the outer diameter of the bolt will be very small, or even the inner diameter of the rubber foot pad and the outer diameter of the bolt will touch. Especially for smaller miniature compressors, when the dimensions of the above components deviate slightly, or when the compressor is slightly displaced due to deformation of the system's intake and exhaust pipeline assembly, the neck of the rubber foot pad may be squeezed by the compressor foot. When the neck of the rubber foot pad is squeezed by the compressor foot, the vibration isolation ability of the rubber foot pad will deteriorate, and at the same time, part of the vibration of the compressor will be directly transmitted to the bottom plate of the unit through the bolts, causing the unit to vibrate and make loud noise during operation; during the start-up / shutdown process of the compressor, the amplitude of the compressor is slightly large, and the compressor foot hits the system bolts, making a "bang" sound; in addition, during long-term use, the neck of the rubber foot pad is squeezed and rubbed by the compressor foot, and the compressor foot has large vibrations during start-up and shutdown, and continuous vibrations during operation. The neck of the rubber foot pad is squeezed and cut between the bolts and the compressor foot, so the neck of the rubber foot pad is also at risk of being cut and broken.

[0003] When the existing support installation structure is applicable, the compressor has only three installation angles to choose from, with each 120° rotation of the compressor housing axis as one installation position. However, when the unit space is insufficient, the installation dimensions cannot be fine-tuned, and the position of the compressor support feet or the position of the unit bottom plate bolts needs to be redesigned, which is a major change.

[0042] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0043] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and their repeated descriptions will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0044] In order to solve the existing technical problems, an embodiment of the present invention provides a vibration-damping support structure suitable for a compressor system, comprising a tray and a chassis for supporting the lower shell cover of the compressor; the tray comprises a tray body that fits with the lower shell cover of the compressor and n tray feet connected to the tray body, and the positions of the tray feet correspond to the positions of the compressor feet; the chassis comprises a chassis body and a connecting part, and the connecting part is respectively connected to the tray body and the chassis body; the chassis body is provided with m first mounting holes for connecting to the bottom plate of the unit.

[0045] The vibration-damping support structure of the present invention, which includes a tray and a chassis, forms an integral whole, replacing the existing support structure composed of multiple separate rubber pads, avoiding the deterioration of the vibration isolation capability due to the neck of a single rubber pad being squeezed by the compressor support foot, and directly transmitting part of the vibration of the compressor to the unit bottom plate through the bolts, resulting in high vibration and noise during the operation of the unit; at the same time, it also avoids the risk of a single rubber pad being squeezed and cut between the bolts and the compressor support foot, and the risk of its neck being cut and broken. In addition, by setting multiple mounting holes on the chassis, more and more flexible compressor installation angles are provided for the compressor.

[0046] The vibration reduction support structure of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the various specific embodiments are not intended to limit the protection scope of the present invention.

[0047] Figure 3 and Figure 4 They are schematic structural diagrams of a vibration-damping support structure and a compressor system including the same according to an embodiment of the present invention, wherein the vibration-damping support structure 9 includes a tray and a chassis for supporting a lower shell cover of the compressor.

[0048] The tray includes a tray body 91 that fits with the lower shell cover of the compressor and n tray feet 92 connected to the tray body 91, and the positions of the tray feet 92 correspond to the positions of the compressor feet. In this embodiment, the tray body 91 is a circular ring-shaped tray. Usually, the cross-section of the lower shell cover of the compressor is an arc-shaped structure that bulges toward the vibration-damping support structure. Correspondingly, the cross-section of the circular ring-shaped tray is a concave arc-shaped structure that matches it. The n tray feet 92 can be arranged on the outer periphery of the circular ring-shaped tray. For example, the existing compressor 1 has three compressor feet 11, and the three compressor feet are evenly distributed along the circumference of the compressor housing. The compressor has three installation positions, that is, one installation position for each rotation of 120°. At this time, correspondingly, the tray includes three tray feet 92, and they are also evenly arranged on the outer periphery of the circular ring-shaped tray.

[0049] The chassis includes a chassis body 93 and a connecting portion 94. In this embodiment, the chassis body 93 is a circular flat plate, and the two ends of the columnar connecting portion 94 are respectively connected to the inner circumference of the circular support plate and the inner circumference of the circular flat plate. The height of the connecting portion and the radial size of the connecting portion can be set according to the actual use scenario.

[0050] The tray and chassis included in the vibration-damping support structure of the present invention may be integrally formed, that is, the vibration-damping support structure is an integrally formed part, and the vibration-damping support structure may be made of an elastic material, preferably, a highly elastic rubber material may be used. When the vibration-damping support structure is an integrally formed part, compared with the existing support structure composed of multiple rubber pads, the force in the circumferential direction is more uniform, thereby avoiding damage to a single rubber pad due to its own installation defects or uneven force at that location, thereby affecting the vibration-damping performance of the support structure. The vibration-damping support structure of the present invention is not limited to the above-mentioned structure.

[0051] Still taking the above embodiment as an example, the chassis body 93 is a circular flat plate, and the chassis body is provided with m first mounting holes 931. In the compressor system, the compressor is connected to the tray of the vibration reduction support structure through the compressor support foot, and then connected to the unit bottom plate through the chassis of the vibration reduction support structure. The above connection method enables the compressor support foot 11 and the unit bottom plate to be directly connected without bolts.

[0052] Furthermore, a plurality of first mounting holes provided through the chassis body can be fixedly connected to the bottom plate of the unit by bolts. In some embodiments, the m first mounting holes are evenly distributed along the circumference of the annular flat plate. It can be seen that the number of first mounting holes, that is, the value of m, determines the number of installation positions of the compressor. Since the number of compressor feet is determined, that is, the number of tray feet of the vibration-damping support structure is determined, usually, more first mounting holes than the number of tray feet can be provided, that is, the number of first mounting holes m is greater than the number of tray feet n. The more the number of first mounting holes, the more installation positions the compressor has. Accordingly, the installation of the compressor is more flexible and can be applied to more installation spaces. At the same time, the more the number of first mounting holes, the more uniform the force on the vibration-damping support structure. The number of first mounting holes can be determined based on the actual use scenario and cost of the compressor, and the present invention does not limit this. Figure 3 In the embodiment, the vibration-damping support structure includes three tray feet 92 and six first mounting holes 931 .

[0053] The embodiment of the present invention further provides a compressor system, comprising a compressor and the vibration reduction support structure 9. Figure 4 As shown, the tray foot 92 of the vibration-damping support structure 9 can be provided with a second mounting hole 921, and correspondingly, the compressor foot 11 is provided with a third mounting hole 111, and the bolts can be connected with nuts through the second mounting hole 921 and the third mounting hole 111 to fix the tray foot 92 and the compressor foot 11.

[0054] Preferably, the compressor system further comprises a flat ring-shaped gasket not in the Figure 4The flat washer matches the shape of the chassis body, and the flat washer, the chassis body and the unit bottom plate are fixedly connected by bolts. The compressor system of the present invention realizes the vibration-damping fixed connection between the compressor and the unit bottom plate through the vibration-damping support structure. During the start-up or shutdown of the compressor, even if the compressor amplitude is slightly large, the compressor support foot will not hit the unit bottom plate bolts to make a "bang" sound, thereby reducing the start-stop noise; at the same time, the compressor support foot and the unit bottom plate connection are separated by the vibration-damping support structure, so that even if the installation size is slightly deviated, the vibration-damping support structure will be slightly deformed, and will not be squeezed by the bolts, and will not have a significant impact on the vibration-damping characteristics of the vibration-damping support structure, and the overall vibration noise of the compressor system will not be significantly deteriorated; in addition, since the vibration-damping support structure of the above structure is subjected to force in the circumferential direction, its deformation caused by the vibration of the compressor is also relatively uniform, and it will not be partially cut or broken by the compressor support foot, thereby improving the reliability of the support structure and the life of the compressor system.

For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is limited by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present application. Any figure mark in the claims should not be regarded as limiting the claims involved. In addition, it should be understood by those skilled in the art that in the disclosure of the present invention, the term "comprising" does not exclude other units or steps, and the singular does not exclude the plural.
