If there is a description of the first and the second, it is only for the purpose of distinguishing technical features, and should not be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features or implicitly specifying the sequence relationship of the indicated technical features.

[0040] In the description of the present utility model, unless otherwise clearly defined, words such as "arrangement", "installation", "connection", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0041] Compressors are widely used in refrigeration equipment such as air conditioners, refrigerators, fresh-keeping cabinets, cold storages, etc. The compressor provides the power for refrigeration by compressing the refrigerant. During the operation of the compressor, vibration will inevitably occur. If it cannot be effectively suppressed and reduced, excessive vibration will not only generate uncomfortable noise and poor user experience, but also cause damage to the compressor itself and the components around the compressor, thus affecting the overall service life and performance of the refrigeration equipment. In order to reduce the generation of vibration, the compressor is generally installed on the base through buffer foot pads, and the buffer foot pads play a role in buffering and vibration reduction.

[0042] In the related art, the buffer foot pads are generally rubber foot pads. The rubber foot pads achieve vibration reduction by absorbing and dispersing vibration energy. When the rubber foot pads are first used, the buffer and vibration reduction effect is relatively excellent. However, the rubber foot pads are long-term located in the high-temperature and high-humidity environment in the compressor compartment, and are easily affected by the high-temperature and high-humidity environment in the compressor compartment and age relatively quickly, resulting in a reduction in the buffer and vibration reduction effect, a reduction in service life, and poor reliability. In addition, the rubber foot pads generally have a good vibration reduction effect on vibrations in the medium and high frequency bands, but have a poor vibration reduction effect on vibrations in the low frequency band.

[0043] Therefore, the present utility model provides a foot pad, a compressor assembly and a refrigeration equipment, which can effectively improve the above problems.

[0044] The following refers to Figures 1 to 6 Describe the foot pad 10, the compressor assembly and the refrigeration equipment according to the embodiments of the present utility model.

[0045] Refer to Figures 1 to 3As shown, the foot pad 10 according to the first aspect embodiment of the present utility model includes a foot pad body 100 and an elastic member 200. The compressor 20 is installed on the base 40 through the foot pad 10 of the present utility model. The foot pad body 100 and the elastic member 200 jointly support the compressor 20 and jointly buffer and dampen the vibration generated by the compressor 20.

[0046] For example, referring to Figures 1 to 3 As shown, the shape of the foot pad body 100 can be designed according to the shape of the position of the compressor 20 for connecting the foot pad body 100 and the shape of the position of the base 40 for supporting the foot pad body 100. For example, when the base 40 is provided with a cylindrical limiting groove, the outer contour of the bottom end of the foot pad body 100 can be set to be cylindrical. An installation cavity 101 is formed inside the foot pad body 100, and the installation cavity 101 can be approximately located at the middle position in the height direction of the foot pad body 100. The shape and size of the installation cavity 101 can be designed according to the shape and size of the elastic member 200. For example, when the elastic member 200 is set as a helical spring, the installation cavity 101 can be cylindrical, and the axis line of the installation cavity 101 can extend vertically to make the matching effect between the installation cavity 101 and the elastic member 200 better. The foot pad body 100 can be prepared from a rubber material or other suitable materials that meet the requirements of damping coefficient and stiffness. For example, it can be prepared from silicone rubber and has high heat resistance and moisture resistance.

[0047] Referring to Figure 3 As shown, the elastic member 200 is installed in the installation cavity 101. The top end of the elastic member 200 abuts against the top wall of the installation cavity 101, and the bottom end of the elastic member 200 abuts against the bottom wall of the installation cavity 101. For example, the top end of the elastic member 200 can be in contact with the surface of the top wall of the installation cavity 101, or can be bonded or clamped to the top wall of the installation cavity 101. The bottom end of the elastic member 200 can be in contact with the surface of the bottom wall of the installation cavity 101, or can be bonded or clamped to the bottom wall of the installation cavity 101. As long as the top wall and the bottom wall of the installation cavity 101 can abut against the elastic member 200. The structure of the elastic member 200 can be various. For example, it can be a helical spring, a disc spring, an elastic sheet, etc. It can be understood that the elastic member 200 can be made of a metal part, has high heat resistance and moisture resistance, and the heat resistance and moisture resistance are greater than that of rubber. It is not easy to fail in a high-temperature and high-humidity environment, so that the anti-aging ability of the elastic member 200 is greater than that of the foot pad body 100 and the service life is longer. Moreover, the stiffness of the elastic member 200 made of metal is greater than the stiffness of the foot pad body 100 made of rubber material. Compared with a rubber foot pad, the compressor 20 is jointly supported by the foot pad body 100 and the elastic member 200, and the support stability is better.

[0048] According to the foot pad 10 of the embodiment of the present utility model, the elastic member 200 is located in the installation cavity 101 of the foot pad body 100, with good sealing performance, which can reduce the influence caused by the high-temperature and high-humidity environment in the compressor chamber. Moreover, the elastic member 200 can be made of materials such as high-temperature and high-humidity resistant metal parts, and is not easily damaged. After long-term use, even if the foot pad body 100 shows a certain degree of aging, the overall foot pad 10 can still have a good buffering and vibration reduction effect, and has a longer service life.

[0049] It should be noted that the foot pad 10 of the present utility model can be used not only for installing the compressor 20, but also for installing other devices that may generate relatively large vibrations, such as motors, pumps, etc.

[0050] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present utility model, the elastic member 200 is set as a helical spring. For example, the axial direction of the helical spring can extend vertically, the installation cavity 101 can be set as a cylindrical shape, the axial direction of the installation cavity 101 can also extend vertically, and the axis of the helical spring can coincide with the central axis of the installation cavity 101.

[0051] In this embodiment, the elastic member 200 is set as a helical spring, which not only has a large elastic compression amount, high elastic deformation ability and resilience. Thus, the buffering and vibration reduction effect on the compressor 20 is better. Moreover, the natural frequency of the helical spring is lower and the support stability is better. In addition, the foot pad body 100 can have a good vibration reduction effect on the vibration in the medium and high frequency bands, and the helical spring with a lower natural frequency can have a good vibration reduction effect on the vibration in the low frequency band. Furthermore, the foot pad 10 of the present utility model has good vibration reduction effects on the low frequency band, medium frequency band and high frequency band. By installing the compressor 20 on a traditional rubber foot pad and on the foot pad 10 of the embodiment of the present utility model, measuring the vibration acceleration when the compressor 20 vibrates, reference Figure 6 As shown, the solid line represents the vibration acceleration measured by the compressor 20 at different speeds when the compressor 20 is installed on a traditional rubber foot pad, and the dashed line represents the vibration acceleration measured by the compressor 20 at different speeds when the compressor 20 is installed on the foot pad 10 of the present utility model. The results show that when the speed of the compressor 20 is between 1020 rpm and 1320 rpm, compared with the traditional pure rubber foot pad, the vibration acceleration generated by the compressor 20 using the foot pad 10 of the present utility model is smaller, and the vibration acceleration is reduced by about 19%. It effectively reduces the transmission of vibration energy, significantly improves the stability and quietness of refrigeration equipment such as refrigerators during operation, provides an efficient and reliable solution for the vibration reduction, noise reduction and stable operation of refrigeration equipment, and has broad market application prospects and important industry promotion value.

[0052] It should be noted that the elastic member 200 can also be of other structures. For example, it can also be a disc spring or an elastic sheet, or the elastic member 200 includes an upper connecting plate, a lower connecting plate, and a plurality of helical springs disposed between the upper connecting plate and the lower connecting plate.

[0053] Referring Figure 4 As shown, in a further embodiment of the present invention, the number of turns of the helical spring is N, satisfying: 3 ≤ N ≤ 8; and / or, the wire diameter of the helical spring is D, satisfying: 2 mm ≤ D ≤ 3 mm; and / or, in the natural state, the height dimension of the helical spring is H, satisfying: 8 mm ≤ H ≤ 14 mm. The number of turns N of the helical spring can be 3, 4, 5, 6, 7, 8. For example, it can be 5 turns. The wire diameter D of the helical spring can be 2 mm, 2.3 mm, 2.5 mm, 2.7 mm, 3 mm or other suitable dimensions. For example, it can be 2.5 mm. Herein, the wire diameter of the helical spring refers to the diameter of the steel wire used to prepare the helical spring. In the natural state, the height dimension H of the helical spring can be 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm or other suitable dimensions. For example, it can be 11 mm.

[0054] When the number of turns, wire diameter, and height dimension of the helical spring are different, its stiffness and damping will change accordingly, and the buffer and vibration reduction effect on the compressor 20 will also change. Through simulation calculation or experimental testing, the parameter range of the spring when the foot pad 10 of the present invention has a better buffer and vibration reduction effect can be obtained: the number of turns N of the helical spring is: 3 ≤ N ≤ 8, the wire diameter D of the helical spring is: 2 mm ≤ D ≤ 3 mm, and in the natural state, the height dimension H of the helical spring is: 8 mm ≤ H ≤ 14 mm. When the parameters of the helical spring are within these ranges, the stiffness and damping coefficient can reach a better range, thereby enabling the foot pad 10 of the present invention to have a better buffer and vibration reduction effect.

[0055] Referring Figure 1 and Figure 3As shown, in some embodiments of the present invention, a first connection hole 102 is provided at the top of the foot pad body 100, and a second connection hole 103 coaxial with the first connection hole 102 is provided at the bottom of the foot pad body 100. The first connection hole 102 and the second connection hole 103 are respectively communicated with the installation cavity 101. For example, when the installation cavity 101 is arranged as a cylinder, the axis lines of the first connection hole 102, the second connection hole 103, and the installation cavity 101 can coincide. The first connection hole 102 is located above the installation cavity 101, and the second connection hole 103 is located below the installation cavity 101. The aperture sizes of the first connection hole 102 and the second connection hole 103 can be similar and smaller than the diameter size of the installation cavity 101. When the elastic member 200 is arranged as a helical spring, the aperture sizes of the first connection hole 102 and the second connection hole 103 are smaller than the outer diameter size of the helical spring.

[0056] In this embodiment, since the foot pad body 100 can generate elastic deformation, the elastic member 200 can be squeezed into and pass through the first connection hole 102 or the second connection hole 103, and then enter the installation cavity 101, thereby realizing the installation of the elastic member 200. The installation is simple and convenient. In addition, it is also more convenient for the compressor 20 to be installed on the base 40 through the foot pad 10 of the present invention. For example, an installation bracket 30 can be provided at the bottom end of the compressor 20. The installation bracket 30 can be provided with a first installation hole corresponding to the foot pad 10, and the base 40 can be provided with a second installation hole corresponding to the foot pad 10. When installing the compressor 20, place the foot pad 10 on the base 40, then support the installation bracket 30 on the foot pad 10, and align the first connection hole 102, the second connection hole 103, the first installation hole, and the second installation hole. Finally, pass the fastener through the first connection hole 102, the second connection hole 103, the first installation hole, and the second installation hole, and tighten the fastener. The installation is simple and convenient, saving time and effort. And when the elastic member 200 is arranged as a helical spring or a disc spring, the helical spring or the disc spring can also be sleeved outside the fastener, thereby facilitating the positioning of the helical spring or the disc spring, and the practicability is better.

[0057] It can be understood that in some other embodiments of the present invention, it can also be that the foot pad body 100 and the installation bracket 30 of the compressor 20 are connected by a first fastener, and the foot pad body 100 and the base 40 are connected by a second fastener, which will not be elaborated here.

[0058] Refer to Figure 1 、 Figure 3 and Figure 5As shown, in a further embodiment of the present utility model, a connection portion 104 is provided at the top end of the foot pad body 100. A connection groove 105 is formed on the outer peripheral wall of the connection portion 104. The connection groove 105 surrounds the connection portion 104, and the first connection hole 102 penetrates through the connection portion 104. For example, the connection groove 105 can be circular ring-shaped, the axis line of the connection groove 105 can coincide with the axis line of the first connection hole 102, the height dimension of the connection groove 105 can be adapted to the thickness dimension of the position of the mounting bracket 30 of the compressor 20 where the first mounting hole is provided, and the diameter dimension of the inner side wall of the connection groove 105 can be adapted to the aperture dimension of the first mounting hole.

[0059] When installing the compressor 20, the top end of the connection portion 104 is elastically deformed to pass through the first mounting hole of the mounting bracket 30, and the position of the mounting bracket 30 where the first mounting hole is provided is sleeved outside the connection groove 105. The installation is simple and convenient, time-saving and labor-saving. Moreover, through the limitation of the connection portion 104 above the connection groove 105, the mounting bracket 30 can be prevented from slipping out randomly, making the installation of the compressor 20 more stable.

[0060] Reference Figures 1 to 3 As shown, further, a flange 106 is provided at the top end of the outer peripheral wall of the connection portion 104. A connection groove 105 is formed between the bottom surface of the flange 106 and the top surface of the foot pad body 100. By providing the flange 106, not only the effect of preventing the mounting bracket 30 from slipping out randomly is better, making the installation of the compressor 20 more stable, but also after installing the fastener, the flange 106 can elastically abut against the nut of the fastener. The elastic flange 106 can play the role of a washer to prevent the nut from loosening, and the practicability is better.

[0061] Reference Figure 3 As shown, in a further embodiment of the present utility model, the aperture diameter of one end of the second connection hole 103 close to the installation cavity 101 gradually increases from bottom to top. When the compressor 20 is installed on the base 40 through the foot pad 10 of the present utility model, generally, the fastener is sequentially passed through the first mounting hole, the first connection hole 102, the second connection hole 103, and the second mounting hole from top to bottom. However, the second connection hole 103 is located below the installation cavity 101. When inserting the fastener, it is difficult to observe the second connection hole 103, which may lead to the fastener being difficult to accurately insert into the second connection hole 103, and it is easy to have a situation where the fastener abuts against the bottom surface of the installation cavity 101, making the installation more troublesome.

[0062] In this embodiment, the aperture diameter of one end of the second connection hole 103 close to the installation cavity 101 gradually increases from bottom to top. In this way, when inserting the fastener, even if the fastener is not completely aligned with the second connection hole 103, the fastener can smoothly slide into the second connection hole 103, making it more convenient to install the fastener, and thus making it more convenient to install the compressor 20.

[0063] In some embodiments of the present utility model, the damping coefficient of the foot pad body 100 is C, satisfying: 0.1 ≤ C ≤ 0.5. The damping coefficient C of the foot pad body 100 can be 0.1, 0.2, 0.3, 0.4, 0.5 or other suitable values. For example, it can be 0.3. Different damping coefficients of the foot pad body 100 will also change the buffer and vibration reduction effect on the compressor 20. Through finite element simulation analysis or experimental testing, the value range of the damping coefficient C of the foot pad body 100 when the foot pad 10 of the present utility model has a better buffer and vibration reduction effect can be obtained: 0.1 ≤ C ≤ 0.5. When the damping coefficient C of the foot pad body 100 is between 0.1 and 0.5, the foot pad 10 of the present utility model can have a better buffer and vibration reduction effect.

[0064] In some embodiments of the present utility model, the stiffness of the foot pad body 100 is K, satisfying: 50 N / mm ≤ K ≤ 250 N / mm. The stiffness K of the foot pad body 100 can be 50 N / mm, 100 N / mm, 150 N / mm, 200 N / mm, 250 N / mm or other suitable values. For example, it can be 150 N / mm. Different stiffnesses of the foot pad body 100 will also change the buffer and vibration reduction effect on the compressor 20. Through finite element simulation analysis or experimental testing, the value range of the stiffness K of the foot pad body 100 when the foot pad 10 of the present utility model has a better buffer and vibration reduction effect can be obtained: 50 N / mm ≤ K ≤ 250 N / mm. When the stiffness K of the foot pad body 100 is between 50 N / mm and 250 N / mm, the foot pad 10 of the present utility model can have a better buffer and vibration reduction effect.

[0065] The following briefly elaborates on obtaining the preferred value ranges of the parameters of the helical spring of the foot pad 10 of the present utility model, as well as the preferred value ranges of the damping coefficient and stiffness of the foot pad body 100 through finite element simulation analysis.

[0066] First, establish a finite element model. Consider the foot pad 10 of the present utility model as an elastic structure body, and perform discretization processing using high-precision three-dimensional solid elements. For the foot pad body 100, use a hyperelastic constitutive model with higher accuracy, and the helical spring can be simulated using a linear spring element. When establishing the finite element model, appropriate boundary conditions and applied loads need to be set to more accurately simulate the actual working conditions.

[0067] After establishing the finite element model, different parameter values are assigned to the helical spring. By comparing and evaluating the relevant vibration data under different helical spring parameter values, such as vibration acceleration, vibration amplitude, vibration transmissibility, etc., the numerical range of the helical spring parameters with the best buffering and vibration reduction effect is determined. Different damping coefficients and stiffness values are assigned to the foot pad body 100. By comparing and evaluating the relevant vibration data of the foot pad body 100 under different damping coefficients and stiffness values, such as vibration acceleration, vibration amplitude, vibration transmissibility, etc., the numerical range of the damping coefficient and stiffness of the foot pad body 100 with the best buffering and vibration reduction effect is determined.

[0068] Reference Figure 5 As shown, the compressor assembly according to the second aspect embodiment of the present invention includes the foot pad 10 according to the first aspect embodiment of the present invention above. For example, the compressor assembly may further include a compressor 20 and a mounting bracket 30. The mounting bracket 30 is provided at the bottom end of the compressor 20. The mounting bracket 30 is provided with a plurality of first mounting holes. A plurality of the foot pads 10 according to the first aspect embodiment of the present invention are correspondingly provided. The base 40 is correspondingly provided with a plurality of second mounting holes. A plurality of foot pads 10 are placed on the base 40. The mounting bracket 30 is supported on the plurality of foot pads 10. The first connection hole 102, the second connection hole 103, the first mounting hole and the second mounting hole are aligned and installed with fasteners.

[0069] According to the compressor assembly of the embodiment of the present invention, by adopting the foot pad 10 of the first aspect embodiment above, the elastic member 200 is located in the installation cavity 101 of the foot pad body 100, and the sealing performance is good, which can reduce the influence caused by the high-temperature and high-humidity environment in the compressor chamber. Moreover, the elastic member 200 can be made of materials such as high-temperature and high-humidity resistant metal parts and is not easily damaged. After long-term use, even if the foot pad body 100 shows a certain degree of aging, the foot pad 10 as a whole can still have a good buffering and vibration reduction effect and a longer service life.

[0070] It can be understood that since the compressor assembly adopts all the technical solutions of the foot pad 10 of the first aspect embodiment above, the compressor assembly at least has all the beneficial effects brought by the technical solutions of the first aspect embodiment above, which will not be elaborated here.

Moreover, the elastic member 200 can be made of materials such as high-temperature and high-humidity resistant metal parts, and is not easily damaged.
