[0025] See also Figures 1 to 3 , Figure 1 It is a front structural schematic diagram of an embodiment of a compressor vibration isolation device of the present application; Figure 2 It is a schematic cross-sectional structure diagram of an embodiment of a compressor vibration isolation device of the present application; Figure 3 It is a front structural schematic diagram of the mounting component of the compressor vibration isolation device of the present application.

[0026] The present application provides a compressor vibration isolation device 10. The compressor vibration isolation device 10 includes a vibration isolation pad 11 and a mounting member 12. The vibration isolation pad 11 includes a first vibration isolation member 111, a second vibration isolation member 112, and a third vibration isolation member 113 connected in sequence. The outer diameter R1 of the first vibration isolation member 111 and the outer diameter R4 of the third vibration isolation member 113 are greater than the outer diameter R2 of the second vibration isolation member 112. A through assembly cavity 114 is formed in the first vibration isolation member 111, the second vibration isolation member 112, and the third vibration isolation member 113. The mounting member 12 is inserted into the assembly cavity 114.

[0027] It can be seen from the above structure that the outer diameter R1 of the first vibration isolator 111 and the outer diameter R4 of the third vibration isolator 113 are greater than the outer diameter R2 of the second vibration isolator 112, so a depression is formed at the second vibration isolator 112, which can be used to snap into the shell structure of the compressor, and the mounting member 12 is used to relatively fix the compressor and the assembly. The vibration isolation pad 11 and the mounting member 12 can reduce the vibration of the compressor while limiting the relative position of the vibration isolation pad 11 itself and the compressor to a certain extent, so as to avoid the vibration isolation pad 11 and the compressor from being offset in the case of vibration, resulting in failure of vibration reduction.

[0028] Further, the mounting member 12 is inserted into the assembly cavity 114, and the mounting member 12 includes a screw 1221, a sleeve 121 and a gasket 1223. The sleeve 121 is sleeved on the outside of the screw 1221, and the sleeve 121 is inserted into the assembly cavity 114, and the tail of the screw 1221 extends outside the sleeve 121. The gasket 1223 is sleeved on the outside of the screw 1221, and the gasket 1223 is located between the sleeve 121 and the head of the screw 1221. The screw 1221, the gasket 1223 and the sleeve 121 are integrally formed. The outer diameter of the gasket 1223 is greater than the diameter of the assembly cavity 114. At this time, the mounting member 12 composed of the integrally formed screw 1221, the gasket 1223 and the sleeve 121 has the advantages of simple assembly and easy standardized operation, which can facilitate the later operation of the production personnel. At the same time, the integrally formed mounting member 12 also has the advantage of lower cost. Furthermore, the outer diameter of the gasket 1223 is larger than the diameter of the assembly cavity 114, and the gasket 1223 can be used to press the first vibration isolation member 111 to avoid the mounting member 12 being unable to engage with the first vibration isolation member 111, and the entire structure of the mounting member 12 being located in the assembly cavity 114, thereby failing to well fix the vibration isolation pad 11 between the compressor and the assembly, making the overall assembly structure unstable, thereby affecting the vibration isolation effect. Therefore, the mounting member 12 structure is a casting, which has the advantages of high strength, easy installation, low cost and good consistency.

[0029] It should be noted that the size of the gasket 1223 can be selected according to actual assembly requirements and is not limited here.

[0030] In some embodiments, a vibration isolation cavity 115 is further formed in the third vibration isolation member 113, and the vibration isolation cavity 115 is arranged around the mounting member 12. By providing the vibration isolation cavity 115, the overall elasticity of the vibration isolation pad 11 can be improved, and then the cavity structure in the vibration isolation cavity 115 can absorb the vibration energy from the compressor to a greater extent, so as to better improve the vibration isolation efficiency of the compressor vibration isolation device 10, thereby ensuring the vibration reduction effect of the compressor vibration isolation device 10, so as to better improve the overall user experience. Furthermore, the vibration isolation cavity 115 is arranged around the mounting member 12, so that during the vibration of the compressor, the assembly between the vibration isolation pad 11 and the compressor and the assembly parts can be more stable, so as to better achieve the vibration reduction effect on the compressor and the assembly parts. Moreover, it is also possible to ensure the energy absorption effect of the compressor vibration isolation device 10 to ensure its vibration reduction effect under the premise of achieving the fixing purpose.

[0031] See also Figures 4 to 5 , Figure 4 It is a three-dimensional structural schematic diagram of the vibration isolation pad of the compressor vibration isolation device of the present application; Figure 5 It is a schematic diagram of the cross-sectional structure of the vibration isolation pad of the compressor vibration isolation device of the present application.

[0032] In some embodiments, the third vibration isolation member 113 includes a first vibration isolation portion 1131, a second vibration isolation portion 1132, and a third vibration isolation portion 1133. The second vibration isolation portion 1132 is arranged around the outer periphery of the mounting member 12. The first vibration isolation portion 1131 connects the second vibration isolation member 112 and the second vibration isolation portion 1132. The third vibration isolation portion 1133 is connected to the end of the second vibration isolation portion 1132 facing away from the first vibration isolation portion 1131, and the third vibration isolation portion 1133 is bent toward the first vibration isolation portion 1131. The first vibration isolation portion 1131, the second vibration isolation portion 1132, and the third vibration isolation portion 1133 surround and form a vibration isolation cavity 115. At this time, when the mounting member 12 is inserted into the assembly cavity 114 and the vibration isolation pad 11 begins to play a vibration isolation role, the vibration isolation cavity 115 can absorb the vibration energy from the compressor to improve the vibration reduction effect of the compressor vibration isolation device 10. Among them, the vibration isolation cavity 115 can be connected to the assembly cavity 114. Of course, in other embodiments, the vibration isolation cavity 115 and the assembly cavity 114 may also be separately and independently provided.

[0033] Furthermore, the third vibration isolation part 1133 has a guide groove 1134 at one end facing the first vibration isolation part 1131, and the guide groove 1134 is connected to the assembly cavity 114. In the direction from the third vibration isolation part 1133 to the first vibration isolation part 1131, the inner diameter of the guide groove 1134 gradually increases. At this time, the setting of the guide groove 1134 can play a certain auxiliary role in the installation part 12 passing through the assembly cavity 114, so as to avoid the installation part 12 being stuck on the third vibration isolation part 1133 during the process of being inserted into the assembly cavity 114. When the operator uses too much force, it is easy to cause damage to the vibration isolation pad 11, thereby affecting the vibration isolation effect of the compressor vibration isolation device 10.

[0034] In some embodiments, the vibration isolation pad 11 is further formed with a vibration reduction cavity 116, which is formed in the third vibration isolation portion 1133, and the vibration reduction cavity 116 is connected to the assembly cavity 114. The setting of the vibration reduction cavity 116 can absorb the vibration energy of the compressor together with the vibration isolation cavity 115, so as to further improve the vibration reduction efficiency of the compressor vibration isolation device 10, thereby better improving the vibration reduction effect of the compressor vibration isolation device 10. In addition, the vibration reduction cavity 116 can also better cooperate with the vibration isolation cavity 115 to ensure the radial vibration isolation effect, so as to improve the vibration reduction effect of the compressor vibration isolation device 10 to a greater extent.

[0035] Please continue reading Figures 1 to 5Since the outer diameter R2 of the second vibration isolator 112 is smaller than the outer diameter R1 of the first vibration isolator 111 and the outer diameter R4 of the third vibration isolator 113, when the compressor is assembled on the vibration isolator 11, the compressor base plate can be clamped between the first vibration isolator 111 and the third vibration isolator 113, thereby limiting the relative position of the compressor and the vibration isolator 11 to a certain extent, so as to avoid the vibration isolation failure caused by the displacement of the vibration isolation pad 11 when the compressor vibrates. In some embodiments, in order to facilitate the vibration isolation pad 11 to be clamped into the compressor base plate from the first vibration isolator 111, the outer diameter R1 of the first vibration isolator 111 is smaller than the outer diameter R4 of the third vibration isolator 113, thereby facilitating the assembly of the vibration isolation pad 11.

[0036] It should be noted that in the embodiment of the present application, the outer diameter R4 of the third vibration isolator 113 is the maximum outer diameter of the third vibration isolator 113 , and therefore in the embodiment of the present application, the outer diameter R4 of the third vibration isolator 113 and the outer diameter R4 of the second vibration isolation part 1132 are the same parameter.

[0037] Furthermore, the outer diameter R4 of the second vibration isolation part 1132 is 20-30 mm, and the difference R4-R3 between the outer diameter R4 of the second vibration isolation part 1132 and the diameter R3 of the vibration isolation cavity 115 is 4-5 mm. At this time, the second vibration isolation part 1132 can meet the selection requirements of the compressor assembly. When the outer diameter of the second vibration isolation part 1132 is determined, the vibration isolation pad 11 of the same series does not need to be changed again. When the difference between the outer diameter R4 of the second vibration isolation part 1132 and the diameter R3 of the vibration isolation cavity 115 is 4-5 mm, at this time, on the one hand, the support stiffness of the vibration isolation pad 11 can be met; on the other hand, the vibration isolation cavity 115 can also be used to absorb the vibration energy of the compressor, thereby effectively improving the vibration reduction performance of the compressor vibration isolation device 10.

[0038] It should be noted that the outer diameter R4 of the second vibration isolation part 1132 can be 20 mm, the outer diameter R4 of the second vibration isolation part 1132 can be 25 mm, and the outer diameter R4 of the second vibration isolation part 1132 can also be 27 mm, which is not limited here. Of course, the difference between the outer diameter R4 of the second vibration isolation part 1132 and the diameter R3 of the vibration isolation cavity 115 can be 4 mm, the difference between the outer diameter R4 of the second vibration isolation part 1132 and the diameter R3 of the vibration isolation cavity 115 can also be 4.2 mm, and the difference between the outer diameter R4 of the second vibration isolation part 1132 and the diameter R3 of the vibration isolation cavity 115 can also be 4.6 mm, which is not limited here.

[0039] In some embodiments, the difference between the inner diameter R5 of the third vibration isolation part 1133 and the outer diameter R7 of the sleeve 121 is 0-2 mm. When the difference between the inner diameter R5 of the third vibration isolation part 1133 and the outer diameter R7 of the sleeve 121 is too large, the vibration isolation pad 11 cannot be effectively fixed. Within this size range, the sleeve 121 can be smoothly inserted into the assembly cavity 114, and the entire assembly process is more convenient and labor-saving. In addition, the risk of the vibration isolation pad 11 falling due to vibration can also be effectively avoided.

[0040] It should be noted that the difference between the inner diameter R5 of the third vibration isolation part 1133 and the outer diameter R7 of the sleeve 121 can be 0.5 mm, the difference between the inner diameter R5 of the third vibration isolation part 1133 and the outer diameter R7 of the sleeve 121 can also be 0.3 mm, and the difference between the inner diameter R5 of the third vibration isolation part 1133 and the outer diameter R7 of the sleeve 121 can also be 0.1 mm. When the difference between the inner diameter R5 of the third vibration isolation part 1133 and the outer diameter R7 of the sleeve 121 is smaller, the assembly between the two can be tighter, thereby effectively avoiding the risk of the vibration isolation pad 11 falling due to vibration, which is not limited here.

[0041] Furthermore, in the extension direction of the assembly cavity 114, the difference between the height H2 of the sleeve 121 and the height H of the vibration isolation pad 11 is 0.2mm-1mm. When the difference between the height H2 of the sleeve 121 and the height H of the vibration isolation pad 11 is less than 0.2mm, the vibration isolation pad 11 will be compressed and fail; and when the difference between the height H2 of the sleeve 121 and the height H of the vibration isolation pad 11 is greater than 1mm, the vibration isolation pad 11 will not be fixed tightly, thereby causing a circulation risk. Therefore, when the difference between the height H2 of the sleeve 121 and the height H of the vibration isolation pad 11 is 0.2mm-1mm, the mounting member 12 will not be directly pressed on the vibration isolation pad 11 when it is fully inserted into the assembly cavity 114. At this time, the vibration isolation pad 11 is still in a free state. Therefore, on the premise of achieving the fixing purpose, the energy absorption effect of the compressor vibration isolation device 10 can be further guaranteed, thereby ensuring its vibration reduction effect. Furthermore, a height H1 of the third vibration isolation portion 1133 in the extension direction of the assembly cavity 114 is 6 mm-7 mm, and at this time, the support performance of the vibration isolation pad 11 can be better met.

[0042] It should be noted that the difference between the height H2 of the sleeve 121 and the height H of the vibration isolation pad 11 can be 1 mm, the difference between the height H2 of the sleeve 121 and the height H of the vibration isolation pad 11 can also be 2 mm, and the difference between the height H2 of the sleeve 121 and the height H of the vibration isolation pad 11 can also be 2.5 mm, which is not limited here. The height H1 of the third vibration isolation part 1133 in the extension direction of the assembly cavity 114 can be 6 mm; the height H1 of the third vibration isolation part 1133 in the extension direction of the assembly cavity 114 can also be 6.5 mm, and the height H1 of the third vibration isolation part 1133 in the extension direction of the assembly cavity 114 can also be 7 mm, which is not limited here.

[0043] In some embodiments, the material of the vibration isolation pad 11 is natural rubber material or butyl rubber material. Natural rubber material and butyl rubber material have long-lasting high elasticity, good vibration isolation, shock isolation and sound insulation performance, and are easy to shape and press, and the shape and size can be freely selected to meet the requirements of stiffness and strength, and they have certain damping performance, can effectively absorb mechanical energy, and are more prominent in absorbing high-frequency vibration energy. Therefore, the vibration isolation pad 11 made of natural rubber and butyl rubber material can, on the one hand, absorb the energy generated by the vibration of the compressor to a greater extent to improve the vibration reduction effect of the compressor vibration isolation device 10; on the other hand, it is easy to shape and press, and can also have higher adaptability during use.

[0044] Another embodiment of the present application provides a refrigerator. The refrigerator adopts any of the above-mentioned compressor vibration isolation devices 10. Among them, the vibration isolation pad 11 is fixed between the refrigerator body and the compressor through the mounting member 12. Specifically, the outer diameters of the first vibration isolation member 111 and the third vibration isolation member 113 are larger than the outer diameter of the second vibration isolation member 112, so a recess is formed at the second vibration isolation member 112, which can be used to snap into the shell structure of the compressor, and the mounting member 12 is used to relatively fix the compressor and the assembly. The vibration isolation pad 11 and the mounting member 12 can play a certain limiting role on the relative position of the vibration isolation pad 11 itself and the compressor while reducing the vibration of the compressor, so as to avoid the vibration isolation pad 11 and the compressor from offsetting their positions in the case of vibration, thereby causing vibration reduction failure. Furthermore, the mounting member 12 is inserted into the assembly cavity 114, and the mounting member 12 includes a screw 1221, a sleeve 121 and a gasket 1223. The sleeve 121 is sleeved on the outside of the screw 1221, and the sleeve 121 is inserted into the assembly cavity 114, and the tail of the screw 1221 extends outside the sleeve 121. The gasket 1223 is sleeved on the outside of the screw 1221, and the gasket 1223 is located between the sleeve 121 and the head of the screw 1221. The screw 1221, the gasket 1223 and the sleeve 121 are integrally formed. The outer diameter of the gasket 1223 is greater than the diameter of the assembly cavity 114. At this time, the mounting part 12 composed of the integrally formed screw 1221, the gasket 1223 and the sleeve 121 has the advantages of simple assembly and easy standardized operation, which can facilitate the later operation of the production personnel. At the same time, the integrally formed mounting part 12 also has the advantage of lower cost. Furthermore, the outer diameter of the gasket 1223 is larger than the diameter of the assembly cavity 114, and the gasket 1223 can be used to press the first vibration isolation member 111 to avoid the situation where the entire structure of the mounting member 12 is located in the assembly cavity 114 when the mounting member 12 cannot be engaged with the first vibration isolation member 111, thereby failing to properly fix the vibration isolation pad 11 between the compressor and the refrigerator body, making the overall assembly structure unstable, thereby affecting the vibration isolation effect.

[0045] It should be noted that the terms "horizontal" and "vertical" do not mean that the parts must be absolutely horizontal or vertical, but can be slightly tilted; the terms "parallel" and "vertical" do not mean that the parts are absolutely parallel or vertical, but can form a certain angle deviation. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. In addition, the terms "center", "longitudinal" and "centering" are not necessarily the same as the "centering".

[0046] The directions or positional relationships indicated by "inside", "outside", "clockwise", "counterclockwise", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the products of the present application are usually placed when in use. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0047] It is to be understood that the meaning of "plurality" herein is at least two, such as two, three, etc., unless there is a special limitation. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices. The term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " herein generally indicates that the associated objects before and after are in an "or" relationship.

[0048] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
