Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a shock-absorbing pad, a compressor assembly, and refrigeration equipment. Background Technology

[0002] The compressor is one of the core components of refrigeration equipment and also a major source of vibration. In related technologies, the compressor is mounted on the base plate of the refrigeration equipment using fasteners. When the compressor runs, the movement of its internal motor causes vibration in the compressor housing, generating noise. To improve noise reduction, current compressors use vibration damping pads installed on the fasteners. Common vibration damping pads are usually cylindrical rubber pads, which are fitted onto the fasteners during installation. When the compressor vibrates, the vibration is cushioned by the rubber pads before being transmitted to the compressor base plate, where it is diffused through the housing connected to the base plate. However, the vibration damping effect of this type of pad is not ideal. Utility Model Content

[0023] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0024] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] This application provides a shock-absorbing pad 100 to solve the problem of unsatisfactory shock absorption capacity of existing shock-absorbing pads 100. The following description will be provided in conjunction with the accompanying drawings.

[0026] In the embodiments of this application, such as Figure 3 As shown, the shock-absorbing pad 100 includes a pad body 10, and at least one cavity is formed inside the pad body 10. The cavity forms a sealed space, and when there are multiple cavities, the multiple cavities are spaced apart from each other. The cavity is filled with fluid.

[0027] The shock-absorbing pad 100 provided in this application has an internal cavity filled with fluid. The fluid has a good absorption effect on vibration and noise, forming a vibration absorption effect inside the pad, which helps to improve the shock absorption effect of the shock-absorbing pad 100.

[0028] The pad body 10 can be made of rubber material, such as butyl rubber, and is made by molding raw rubber in one piece using a plasticizing process.

[0029] The pad body 10 has a central axis, the extension direction of which is the axial direction of the pad body 10. The pad body 10 has a through hole 4 extending axially, the through hole 4 for fasteners to pass through. In actual application, the compressor is fixed to the base plate by fasteners, and the pad body 10 is sleeved on the fasteners to achieve shock absorption.

[0030] The pad body 10 may contain one or more cavities. When multiple cavities are provided, they can be distributed in any manner within the pad body 10. In one embodiment, the multiple cavities are evenly distributed, thus ensuring uniform absorption of vibrations at all locations.

[0031] The fluid refers to a fluid that can flow, is compressible and deformable, and absorbs vibrations. Specifically, the fluid can be a gas or a liquid, such as air, water, or grease.

[0032] In one embodiment, the cavity is provided in multiple parts, and at least two of the cavities are filled with different fluids. Since the filling materials of different materials have different inherent frequencies, the shock-absorbing pad 100 proposed in this embodiment can better adapt to the changes in the vibration source frequency caused by changes in the compressor's rotational speed, thus achieving a better shock absorption effect.

[0033] The pad body 10 has a top end 12 and a bottom end 11 disposed opposite to each other in the axial direction of the pad body 10. Please refer to [link / reference]. Figure 3 The system comprises multiple cavities, which are spaced apart along the axial direction. This helps to enhance the axial damping effect. Furthermore, the cavity closest to the bottom end 11 is designated as the second cavity 2, and the cavity closest to the top end 12 is designated as the first cavity 1. The compressibility of the fluid in the second cavity 2 is less than that of the fluid in the first cavity 1. Compressibility refers to the property of a fluid to change volume under pressure at a constant temperature. Filling the second cavity 2 with a fluid with lower compressibility achieves better damping and also helps to strengthen the bottom end 11.

[0034] Furthermore, in one embodiment, the cavities are provided with at least three, and in two adjacent cavities, the compressibility of the fluid in the cavity closer to the top end 12 is greater than or equal to the compressibility of the fluid in the cavity closer to the bottom end 11.

[0035] In one specific embodiment, the cavity is provided with three cavities, including a first cavity 1, a second cavity 2, and a third cavity 3 located between the first cavity 1 and the second cavity 2. The fluid filled in the first cavity 1 is air, the fluid filled in the second cavity 2 is liquid, and the fluid filled in the third cavity 3 is air. This embodiment uses a multi-stage composite vibration damping pad 100 with a simple structure and high reliability. It utilizes the principle that the amplitude and frequency of vibration change when passing through different materials to achieve multi-stage noise reduction and vibration reduction by air and liquid. The vibration generated by the compressor operation is transmitted through plastic materials, absorbed by liquid materials and air, and finally achieves the effect of vibration damping and noise reduction. Furthermore, the second cavity 2 near the bottom 11 is filled with a liquid with low compressibility, which helps to absorb vibration and improve the bottom hardness at the same time. In addition, the liquid has a higher density, so the bottom 11 is heavier than the top 12, which helps to improve the stability of the vibration damping pad 100. The liquid filled in the second cavity 2 can be any liquid such as water or grease that does not chemically react with the material of the pad body 10.

[0036] The cavity serves to form a cavity that can be filled with fluid. Its specific shape can take various forms, including cube, sphere, cylinder, or other irregular shapes; this application does not impose any limitations on this. In some embodiments, the cavity is configured as an annular cavity extending along the circumferential direction of the pad body 10, surrounding the central axis of the pad body 10. This structure is simple and easy to manufacture. In other embodiments, the cavity can be configured as a structure formed by combining multiple sub-cavities spaced apart along the circumferential direction of the pad body 10. A spacer is formed between adjacent sub-cavities. The spacer can be made of rubber material or integrally molded with the pad body 10. The spacer helps to improve the support of the pad body 10.

[0037] See also Figure 1 and Figure 2 In one embodiment, the projected area of ​​the bottom end 11 along the axial direction is larger than the projected area of ​​the top end 12 along the axial direction. The outer diameter of the bottom end 11 is larger than the outer diameter of the top end 12, and the pad body 10 is generally inverted T-shaped. In this way, when the shock-absorbing pad 100 is installed on the base plate, the assembly contact area between the pad body 10 and the base plate is increased, which helps to enhance the stability of the shock-absorbing pad 100 after assembly, improve the problem of the shock-absorbing pad 100 being deformed by pressure, twisting and tilting after assembly, avoid the dispersion of vibration transmission direction due to tilting and deformation, and thus achieve the purpose of reducing overall vibration and noise.

[0038] To achieve this structural design, in one specific embodiment, the pad body 10 includes a plurality of ring portions 5, which are stacked along the axial direction and together define a through hole 4 extending along the axial direction for fasteners to pass through; the outer diameter of the ring portions 5 gradually increases in the direction from the top end 12 to the bottom end 11.

[0039] Based on this embodiment, when multiple cavities are provided, one cavity is correspondingly provided on each of the ring portions 5. In this way, multiple cavities can be distributed along the axial direction.

[0040] This application embodiment also provides a compressor assembly, which includes a compressor (not shown in the figure), a base plate (not shown in the figure), fasteners (not shown in the figure), and a vibration damping pad 100. The vibration damping pad 100 includes a pad body 10, within which at least one cavity is formed, and the cavity is filled with fluid. The specific structure of the pad body 10 can be referred to in the above embodiments. Since this compressor assembly adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The compressor is fixedly mounted on the base plate by the fasteners, and the vibration damping pad 100 is sleeved on the fasteners. The top end 12 of the vibration damping pad 100 abuts against the compressor, and the bottom end 11 of the vibration damping pad 100 abuts against the base plate. Due to the installation of the vibration damping pad 100, the vibration generated by the compressor during operation can be effectively absorbed by the vibration damping pad 100, thereby significantly reducing the noise of the compressor assembly.

[0041] The fasteners may include bolts and bushings. During actual installation, the bushing is fitted around the outer circumference of the bolt, and the shock-absorbing pad 100 is fitted around the outer circumference of the bushing. Then, the compressor feet are fixed to the base plate using bolts. It is understood that the compressor may have multiple feet, and correspondingly, the compressor assembly includes multiple fasteners and multiple shock-absorbing pads 100, with each of the multiple feet, fasteners, and shock-absorbing pads 100 installed in a one-to-one correspondence.

[0042] Furthermore, this application also proposes a refrigeration device, such as a refrigerator or freezer. The refrigeration device includes the compressor assembly described above, which operates with less noise, thus improving the user experience.
