[0002] Rotary compressors are widely used in the field of air conditioning due to their simple structure and low cost. Rotary compressors are generally composed of a main cylinder, a liquid storage tank, a base and rubber pads.

After actual installation, the rubber pads are subjected to different forces, and it is impossible to achieve the best vibration reduction effect for all three pads.

[0003] Once the compressor foot pad structure is fixed, its structural rigidity is basically fixed, but the foot pad has different rigidity requirements under different working conditions or when matching different compressors. For example, during transportation, the foot pad needs to have a larger rigidity to prevent large deformation of the foot pad, which may cause damage to the pipeline, or deformation due to collision with sheet metal. During operation, the vibration isolation rate of the foot pad is related to the load it bears, and the operating frequency of the compressor covers 10-106Hz from low frequency to high frequency, and it is difficult for homogeneous foot pads to achieve good vibration reduction effects.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0043] The present invention fills the pad body with a non-Newtonian fluid filler, and utilizes the different shear pressures, viscosities, and rigidities of non-Newtonian fluids to design vibration-damping pads that exhibit different stiffnesses under different stress conditions, thereby absorbing the energy generated by different vibrations of the compressor cylinder. At the same time, the porosity and strength of different areas of the pad are different through the shape design of the pad body, thereby adjusting the local stiffness of the pad. The vibration-damping pad of the present invention has the dual effects of shape and Newtonian fluid, so that the pad exhibits different stiffness changes. When the operating frequency of the compressor changes, the vibration energy is absorbed by different layers of the pads, thereby achieving an adaptive vibration reduction effect, and can be used with different compressors. The present invention is described in detail below in conjunction with specific embodiments:

[0044] like Figure 1 , Figure 2 As shown, the present invention provides a vibration-damping foot pad 10, including a foot pad body, a non-Newtonian fluid filler is arranged inside the foot pad body, and the non-Newtonian fluid filler and the foot pad body form an integral structure. The vibration-damping foot pad 10 is used to support equipment such as compressors and motors that generate certain vibrations during operation, thereby absorbing part of the vibration energy and reducing the impact of vibration on the equipment. In this embodiment, it is mainly used on compressors.

[0045] Preferably, in this embodiment, the pad body and the non-Newtonian fluid filler can be formed separately, that is, a cavity is preset inside the pad body when the pad body is formed, and the non-Newtonian fluid filler is injected into the cavity after the pad body is formed. Alternatively, the pad body and the non-Newtonian fluid filler can be formed as one piece, for example, the non-Newtonian fluid filler is wrapped with a material with a lower melting point in advance, and is integrally injection molded with the pad body. During the injection molding process, the material wrapping the non-Newtonian fluid filler melts, so that the pad body and the non-Newtonian fluid filling structure form an integral structure.

[0046] Specifically, an upper mounting structure 1 and a lower mounting structure 2 are respectively provided at both ends of the foot pad body, wherein the upper mounting structure 1 is used to connect to the base of equipment such as a compressor or a motor, and the lower mounting structure 2 is used to connect to the base of a fixed compressor or a motor. Preferably, the upper mounting structure 1 and the lower mounting structure 2 are solid structures, so that they have high rigidity and improve the reliability of the connection. A plurality of vibration-damping sections are provided between the upper mounting structure 1 and the lower mounting structure 2, and non-Newtonian fluid fillers are provided in the vibration-damping sections, and a non-Newtonian fluid filling cavity is formed in each vibration-damping section, and the non-Newtonian fluid filling cavities in different vibration-damping sections have different shapes, and / or different types of non-Newtonian fluid fillers are provided in the non-Newtonian fluid filling cavities in different vibration-damping sections.

[0047] Preferably, the foot pad body is a cylindrical structure, and the internal cavity can be installed with bolts and other connecting parts. The outer wall of the upper mounting structure 1 is formed with a first limiting groove 11, and the first limiting groove 11 is preferably an annular groove formed along the circumference of the outer wall of the upper mounting structure 1. The base of the compressor can be inserted into the first limiting groove 11 to fix the base. The lower mounting structure 2 is formed with a concave second limiting groove 21 on the end surface, and the second limiting groove 21 is used to cooperate with the protrusion and other structures on the base to limit the foot pad body.

[0048] The vibration reduction section includes a plurality of vibration reduction sections distributed along the axial direction, and each vibration reduction section is provided with a non-Newtonian fluid filler. Preferably, the non-Newtonian fluid filler in each vibration reduction section is different, and specifically can be different in shape, filling material, material performance, etc., so as to achieve a gradient difference in the stiffness and other performances of each vibration reduction section.

[0049] In a preferred embodiment, the vibration-damping section includes: a first vibration-damping section 31 connected to the upper mounting structure 1, a second vibration-damping section 32 connected to the lower mounting structure 2, and a third vibration-damping section 33 arranged between the first vibration-damping section 31 and the second vibration-damping section 32. The first vibration-damping section 31 and the second vibration-damping section 32 are cylindrical structures, wherein the outer diameter of the second vibration-damping section 32 is greater than the outer diameter of the first vibration-damping section 31, the third vibration-damping section 33 is a truncated cone cylindrical structure, the first end of the third vibration-damping section 33 is connected to the first vibration-damping section 31, and the outer diameter of the first end is the same as the outer diameter of the first vibration-damping section 31, and the second end of the third vibration-damping section 33 is connected to the second vibration-damping section 32, and the outer diameter of the second end is the same as the outer diameter of the second vibration-damping section 32. The above-mentioned structure of the vibration-damping section enables the foot pad body to form a structure with a small upper size and a large lower size as a whole, preferably a structure with a size gradually increasing from top to bottom, thereby improving its compressive resistance. Preferably, in other embodiments, the vibration-damping section may also include multiple sections.

[0050] The non-Newtonian fluid filler is an annular structure arranged around the circumference of the foot pad body, or the non-Newtonian fluid filler is a multi-segment structure distributed around the circumference of the foot pad body.

[0051] The non-Newtonian fluid filler includes: a first non-Newtonian fluid filler 41 disposed inside the first vibration damping section 31 ; a second non-Newtonian fluid filler 42 disposed inside the second vibration damping section 32 ; and a third non-Newtonian fluid filler 43 disposed inside the third vibration damping section 33 .

[0052] In this embodiment, the first non-Newtonian fluid filling cavity is a circular ring structure, the side wall of the circular ring structure is a conical cylinder structure, and the end size of the first non-Newtonian fluid filling cavity close to the upper mounting structure 1 is smaller than the end size of the first non-Newtonian fluid filling cavity close to the third vibration reduction section 33. Further, the cross section of the first non-Newtonian fluid filling cavity is an inclined "capsule-shaped" structure, with two parallel side surfaces, an upper arc surface protruding upward, and a lower arc surface protruding downward. Preferably, the two side surfaces of the first non-Newtonian fluid filling cavity and the axis of the first vibration reduction section 31 form an angle α, preferably, α is 45°, and the shape of the first non-Newtonian fluid filler 41 is the same as that of the first non-Newtonian fluid filling cavity. This shape makes it easier for the force generated by the vibration of the compressor cylinder to act on the first non-Newtonian fluid filler 41 in the form of shear force, and better utilizes the "shear thickening" characteristics of the first non-Newtonian fluid filler 41 to support the upper mounting structure 1.

[0053] The first non-Newtonian fluid filler 41 is a shear-thickening non-Newtonian fluid, and its steady-state shear-thinning rheological curve is as follows: Figure 4 As shown, preferably, the first non-Newtonian fluid filler 41 is composed of SiO2 / PEG200 non-Newtonian fluid, wherein the volume percentage of SiO2 to PEG200 is 23% to 30%, and shear thickening is achieved quickly. Further, in other embodiments, the first non-Newtonian fluid filler 41 can also be composed of other types of non-Newtonian fluids, such as corn starch.

[0054] The third non-Newtonian fluid filling chamber is a circular ring structure, and a plurality of third non-Newtonian fluid filling chambers are provided, and the radial dimensions of the plurality of third non-Newtonian fluid filling chambers are different from each other, so that the plurality of third non-Newtonian fluid filling chambers are staggered in the radial direction. In the present embodiment, the cross section of the third non-Newtonian fluid filling chamber is circular, and preferably, the cross-sectional dimension of the third non-Newtonian fluid filling chamber is small, and three third non-Newtonian fluid fillers 43 are provided, and the radial dimensions of the three third non-Newtonian fluid filling chambers are different, and they are staggered in the axial direction. Preferably, on the axial section of the third vibration damping section 33, the three third non-Newtonian fluid fillers 43 are distributed on the three vertices of an isosceles triangle. Furthermore, the third Newtonian fluid filling structure located on the uppermost side is located at the intersection of the third vibration damping section 33 and the first vibration damping section 31.

[0055] The third non-Newtonian fluid filler 43 has the same shape as the third non-Newtonian fluid filling cavity, and is designed as a small circular structure, and is divided into multiple areas, so as to keep the third vibration damping section 33 as strong as possible, so as to support and fix the compressor cylinder in a steady state. This embodiment provides three circular cavity structures, but is not limited to circular shapes and numbers; the third Newtonian fluid filling structure located on the uppermost side is located at the intersection of the third vibration damping section 33 and the first vibration damping section 31, which is conducive to the transmission of force; the other two circular structures are scattered in other areas, so as to better utilize the "shear thinning" characteristics of the third non-Newtonian fluid filler 43, reduce the stiffness of the third vibration damping section 33, and absorb as much energy as possible under the larger vibration of the compressor cylinder.

[0056] The third non-Newtonian fluid filler 43 is a shear-thinning non-Newtonian fluid, and its steady-state shear-thinning rheological curve is as follows: Figure 5 As shown, preferably, the second non-Newtonian fluid filler 42 is composed of CMC / glycerol 50 non-Newtonian fluid, wherein the volume percentage of CMC is greater than 0.7%, and the larger viscosity change is conducive to absorbing impact forces of different values, absorbing vibration energy to the maximum extent, and adapting to different compressor types. Further, in other embodiments, the third non-Newtonian fluid filler 43 can also be composed of other types of non-Newtonian fluids, such as corn starch.

[0057] The second non-Newtonian fluid filling cavity is designed as a relatively large circular annular structure, and its cross section is a circle larger than the cross section size of the third non-Newtonian fluid filling cavity. The second non-Newtonian fluid filler 42 has the same shape as the second non-Newtonian fluid filling cavity, and is composed of a shear-thickening non-Newtonian fluid, and compared with the first non-Newtonian fluid filler 41, its shear force viscosity and stiffness change or response speed is lower, so that there is a certain time difference between the first vibration reduction section 31 and the second vibration reduction section 32 in the process of stiffness change, and there is a certain hysteresis effect during the operation of the compressor, which can achieve the purpose of adaptively absorbing vibration energy and better adapt to the vibration formation of different compressor cylinders.

[0058] Preferably, the second non-Newtonian fluid filler 42 is composed of SiO2 / PEG200 non-Newtonian fluid, wherein the volume percentage of SiO2 in PEG200 is 13% to 18%, and shear thickening is achieved more slowly. There is a gradient difference between the two, which realizes the stiffness change of different layers of the foot pad, realizes the response time difference, and achieves the purpose of self-adaptation. Furthermore, in other embodiments, the second non-Newtonian fluid filler 42 can also be composed of other types of non-Newtonian fluids, such as corn starch.

[0059] like Figure 3As shown, the present invention also provides a compressor 20, including the above-mentioned vibration-damping pad 10, the compressor 20 includes three base feet, each of the three base feet is installed in cooperation with a vibration-damping pad 10, and the compressor 20 is supported and fixed by three shock-absorbing rubber pads to achieve the three pads being in the best vibration-damping state under different working conditions and different compressors 20, as well as the universality of different models.
