[0026] See also Figures 1 to 3 , Figure 1 is a front structural schematic diagram of an embodiment of a vibration absorber of the present application; Figure 2It is a schematic diagram of the explosion structure of an embodiment of the vibration absorber of the present application; Figure 3 yes Figure 1 A schematic cross-sectional view of an embodiment along the AA direction.
[0027] An embodiment of the present application provides a vibration absorber 10. The vibration absorber 10 includes a support 11, a mounting shell 13 and a vibration absorbing system 12. The mounting shell 13 is disposed on the support 11. The vibration absorbing system 12 is disposed in the mounting shell 13. The vibration absorbing system 12 includes a mass block 121 and at least two first elastic members 122. The mass block 121 is spaced apart from the inner wall of the mounting shell 13. One end of the first elastic member 122 is connected to the mass block 121, and the other end is connected to the inner wall of the mounting shell 13. At least two first elastic members 122 are located on opposite sides of the mass block 121 in the first direction X.
[0028] It can be seen from the above structure that the vibration absorption system 12 composed of the mass block 121 and at least two first elastic members 122 can achieve resonance with the main vibration system where the vibration absorber 10 is arranged. The reaction force of the vibration absorption system 12 when resonance occurs can absorb the vibration energy of the main vibration system in the first direction X to reduce the vibration of the main vibration system, thereby achieving a good vibration isolation purpose. In addition, the provision of at least two first elastic members 122 can absorb a small part of the vibration energy in the remaining directions, and the vibration isolation effect is better. Therefore, this structure can effectively overcome the technical problems of high heat generation and fast performance attenuation of traditional resistive vibration isolation technology through the resonance between the vibration absorption system 12 and the main vibration system, and its overall vibration isolation effect is more stable, so that the vibration isolation effect does not attenuate. Furthermore, the provision of the support 11 and the mounting shell 13 can also well enhance the vibration isolation effect of the overall structure.
[0029] It should be noted that, in order to place the vibration absorbing system 12 inside the installation shell 13 , the interior is hollow to form an installation cavity, wherein the inner wall of the installation shell 13 is a solid structure surrounding the installation cavity.
[0030] See also Figure 6 , Figure 6 It should be noted that the vibration frequency of the main vibration system in the embodiment of the present application is ω0. In order to ensure the vibration absorption effect of the vibration absorber 10, the effective frequency ω1 of the vibration absorber 10 should be the same as the vibration frequency ω0 of the main vibration system. Therefore, the effective frequency of the vibration absorber 10 is The vibration frequency of the system without damping is Critical Damping Ratio Therefore, it can be known from the above formula that the effective frequency ω1 of the vibration absorber 10 is related to the three basic vibration parameters of the mass m of the mass block 121, the system damping coefficient c, and the stiffness k of the first elastic member 122 in the vibration absorption system 12. Therefore, the vibration absorber 10 only needs to adjust the mass m of the mass block 121, the system damping coefficient c, and the stiffness k of the first elastic member 122 to enable the vibration absorber 10 to match a variety of main vibration systems with different vibration frequencies. The overall adaptability of the vibration absorber 10 is stronger, and by setting the vibration absorber 10, the effective frequency ω1 of the vibration absorber 10 can be made the same as the vibration frequency ω0 of the main vibration system, thereby achieving resonance between the vibration absorber 10 and the main vibration system, and absorbing the vibration energy of the main vibration system through the reaction force of the vibration absorber 10 when resonance occurs, thereby reducing the vibration of the main vibration system, so as to achieve the purpose of better vibration isolation.
[0031] See also Figure 4 , Figure 4 yes Figure 1 A schematic diagram of the cross-sectional structure of another embodiment in the AA direction. In an embodiment of the present application, the vibration absorption system 12 also includes at least two second elastic members 123, and the at least two second elastic members 123 are located on opposite sides of the mass block 121 in the second direction Y. The second direction Y intersects with the first direction X. At this time, the vibration absorption system 12 can absorb the vibration energy of the main vibration system in the second direction Y to reduce the vibration of the main vibration system, thereby achieving a good vibration isolation purpose. At the same time, the provision of at least two second elastic members 123 can also absorb a small portion of the vibration energy in the remaining directions, and the vibration isolation effect is better.
[0032] See also Figure 5 , Figure 5 yes Figure 1 A schematic diagram of the cross-sectional structure of another embodiment in the BB direction. Furthermore, the vibration absorption system 12 also includes at least two third elastic members 124, and at least two third elastic members 124 are located on opposite sides of the mass block 121 in the third direction Z. Among them, the first direction X, the second direction Y and the third direction Z intersect each other. At this time, the vibration absorption system 12 can absorb the vibration energy of the main vibration system in the third direction Z to reduce the vibration of the main vibration system, thereby achieving a good vibration isolation purpose. At the same time, the provision of at least two third elastic members 124 can absorb a small part of the vibration energy in the remaining directions, and the vibration isolation effect is better.
[0033] It should be noted that the first direction X, the second direction Y and the third direction Z in the figure are only one arrangement method, but are not limited to the arrangement method in the figure. The first direction X can also be other directions, such as the direction where the second direction Y in the figure is located or the direction where the third direction Z in the figure is located. At this time, the second direction Y or the third direction Z also changes accordingly, and they can keep intersecting with the first direction X in pairs.
[0034] Please continue reading Figures 1 to 5 In an embodiment of the present application, the support 11 is detachably connected to the mounting shell 13. At this time, when the vibration frequency of the main vibration system changes, it is necessary to select a suitable vibration absorption system 12 to absorb the energy of the main vibration system. By arranging the support 11 and the mounting shell 13 to be detachably connected, the vibration absorption system 12 can be replaced by removing the mounting shell 13, so that the vibration frequency of the vibration absorber 10 is consistent with the vibration frequency of the main vibration system, thereby enabling the vibration absorber 10 to resonate with the main vibration system. After the replacement is completed, the mounting shell 13 is installed on the support 11 again, so that the vibration absorber 10 can vibrate again to absorb the energy of the main vibration system. Therefore, the support 11 and the mounting shell 13 are detachably connected, which can make the disassembly and replacement of the vibration absorption system 12 more convenient, thereby effectively increasing the overall adaptability of the vibration absorber 10.
[0035] Furthermore, the mounting shell 13 includes a mounting shell body 132 and a mounting seat 133. The interior of the mounting shell 13 is hollow. The vibration absorption system 12 is arranged in the mounting shell body 132. The support 11 has a support column 141 on the side facing the mounting shell 13, and the support column 141 is threadedly connected to the mounting seat 133. Specifically, the mounting shell 13 is hollow, which can better place the vibration absorption system 12. The setting of the support column 141, on the one hand, can make the connection between the support 11 and the mounting seat 133 more stable, so that when the vibration absorber 10 absorbs the vibration energy of the main vibration system, the entire vibration absorber 10 system can be more stable; on the other hand, it can realize a detachable connection between the support 11 and the mounting seat 133. At this time, the vibration absorption system 12 can be replaced by removing the mounting shell 13, so that the vibration frequency of the vibration absorber 10 is consistent with the vibration frequency of the main vibration system, so that the vibration absorber 10 resonates with the main vibration system to achieve the purpose of vibration reduction.
[0036] It should be noted that, in other embodiments, the support 11 and the mounting shell 13 may be detachably connected by gluing, or the support 11 and the mounting shell 13 may be detachably connected by riveting, which is not limited here.
[0037] In the embodiment of the present application, the mounting shell body 132 has a first opening 134, wherein the mounting seat 133 is covered and arranged on the first opening 134. Specifically, when the mounting shell 13 is in the process of manufacturing, the staff puts the vibration absorbing system 12 into the mounting shell body 132 from the first opening 134, and covers the first opening 134 with the mounting seat 133, so that the vibration absorbing system 12 will not fall off from the mounting shell body 132, and the entire vibration absorbing system 12 can be more stable. When the first opening 134 is perpendicular to the first direction X, at this time, one end of one of the first elastic members 122 is connected to the mass block 121, and the other end is connected to the mounting shell body 132, wherein another first elastic member 122 is connected to the mass block 121 at one end, and the other end is connected to the end face of the mounting seat 133 facing one end of the mounting shell body 132.
[0038] It should be noted that the mounting shell body 132 and the mounting seat 133 can be detachably connected, or fixedly connected, which is not limited here. When the mounting shell body 132 and the mounting seat 133 are detachably connected, the mounting shell body 132 and the mounting seat 133 can be detachably connected by means of screws or rivets. At this time, it is convenient to adjust the mass block 121, the system damping coefficient c, the stiffness k of the first elastic member 122, the second elastic member 123 or the third elastic member 124 of the vibration absorption system 12 when the vibration frequency of the main vibration system changes during later use, so that the vibration frequency of the vibration absorber 10 is consistent with the vibration frequency of the main vibration system, and resonance can be achieved. The vibration absorber 10 can absorb the vibration frequency of the main vibration system and achieve the effect of vibration reduction. When the mounting shell body 132 and the mounting seat 133 are fixedly connected, the mounting shell body 132 and the mounting seat 133 can be fixedly connected by welding. At this time, when the vibration frequency of the main vibration system changes, the entire mounting shell 13 and the vibration absorption system 12 arranged inside the mounting shell 13 can be replaced as a whole, so that the vibration frequency of the replaced mounting shell 13 and the vibration absorption system 12 as a whole can be kept consistent with the vibration frequency of the main vibration system to achieve resonance, and then the vibration absorber 10 can absorb the vibration energy of the main vibration system to achieve the effect of vibration reduction.
[0039] In the embodiment of the present application, the first elastic member 122 is a spring or an elastic steel sheet; and / or, the second elastic member 123 is a spring or an elastic steel sheet; and / or, the third elastic member 124 is a spring or an elastic steel sheet. At this time, the first elastic member 122, the second elastic member 123 and the third elastic member 124 can form a vibration absorption system 12 with the mass block 121, and absorb the vibration energy of the main vibration system by resonating with the main vibration system, thereby achieving the effect of reducing vibration. The spring and the elastic steel sheet have a simple structure and are easy to install, and can have a good vibration absorption effect when combined with the mass block 121.
[0040] It should be noted that the first elastic member 122, the second elastic member 123 and the third elastic member 124 can be springs at the same time; the first elastic member 122, the second elastic member 123 and the third elastic member 124 can be elastic steel sheets at the same time; one of the first elastic member 122, the second elastic member 123 and the third elastic member 124 can be a spring, and the other two can be elastic steel sheets; of course, the first elastic member 122, the second elastic member 123 and the third elastic member 124 can also be two of which are springs and the other one is an elastic steel sheet, which will not be repeated here.
[0041] Of course, in other embodiments, the first elastic member 122 , the second elastic member 123 and the third elastic member 124 may also be made of elastic materials such as torsion springs, which is not limited here.
[0042] In the embodiment of the present application, the mounting shell 13 is made of a rigid material. Since the rigid material has the characteristics of strong tensile strength and high hardness. Therefore, the mounting shell 13 made of a rigid material can effectively prevent the mounting shell 13 from resonating during the resonance between the vibration absorption system 12 and the main vibration system, so the rigid material can effectively prevent the mounting shell 13 from resonating. In addition, the mounting shell 13 is set to a rigid material, which can also better enhance the vibration isolation effect of the overall structure and further reduce the vibration intensity of the main vibration system.
[0043] It should be noted that the rigid material of the mounting shell 13 can be carbon steel or alloy steel, which is not limited here.
[0044] In order to make the connection between the support 11 and the main vibration system more convenient, the support 11 has magnetism. When the support 11 has magnetism, the connection between the support 11 and the main vibration system can be achieved by only using the magnetic force of the support 11. The whole connection process is simple and convenient, and is easy for the operator to use.
[0045] It should be noted that the support 11 and the main vibration system may be connected by gluing or by bolting, which is not limited here.
[0046] Furthermore, the side of the support 11 facing away from the mounting shell 13 is a planar structure. The side of the support 11 facing away from the mounting shell 13 is used to connect with the main vibration system. Since the planar structure can adapt to a variety of different shapes and sizes of designs, when the bottom surface of the support 11 is set as a planar structure, the vibration absorber 10 can be adsorbed on the main vibration system of different sizes or shapes, and its overall adaptability is strong, and its adsorption force can also be guaranteed. Of course, in some other embodiments, the side of the support 11 facing away from the mounting shell 13 can also be a non-planar structure, in which case it is specifically set according to the specific structure of the main vibration system.
[0047] It should be noted that when the side of the support 11 facing away from the mounting shell 13 is a non-planar structure, it may be a curved surface structure or other structures, which are not limited here.
[0048] In another embodiment of the present application, a compressor is provided. The compressor adopts the vibration absorber 10 in any of the above embodiments. And the support of the vibration absorber 10 is arranged on the compressor body. At this time, the vibration absorption system 12 composed of the mass block 121 and at least two first elastic members 122 can achieve resonance with the compressor, and the reaction force of the vibration absorption system 12 when resonance occurs can absorb the vibration energy of the compressor in the first direction X to reduce the vibration of the main vibration system, thereby achieving the purpose of good vibration isolation. Moreover, the setting of at least two first elastic members 122 can absorb a small part of the vibration energy in the remaining directions, and the vibration isolation effect is better. Therefore, this structure can effectively overcome the technical problems of high heat generation and fast performance attenuation of traditional resistive vibration isolation technology through the resonance between the vibration absorption system 12 and the compressor, and its overall vibration isolation effect is more stable, so that there is no attenuation of the vibration isolation effect. Furthermore, the setting of the support 11 and the mounting shell 13 can also well enhance the vibration isolation effect of the overall structure.
[0049] Another embodiment of the present application provides a refrigerator. The refrigerator includes any of the above-mentioned vibration absorbers 10. The vibration absorber 10 is arranged on the compressor of the refrigerator, or on the back panel or side panel of the refrigerator, and is used to absorb the vibration generated by the compressor and / or other components. At this time, the vibration absorber 10 can achieve resonance with the main vibration system where the vibration absorber 10 is arranged through the vibration absorption system 12 composed of the mass block 121 and at least two first elastic members 122. The reaction force of the vibration absorption system 12 when resonance occurs can absorb the vibration energy of the main vibration system in the first direction X to reduce the vibration of the main vibration system, thereby achieving a good vibration isolation purpose. In addition, the provision of at least two first elastic members 122 can absorb a small part of the vibration energy in the remaining directions, and the vibration isolation effect is better. In addition, the vibration frequency of the refrigerator can be made smaller to further improve the overall user experience.
[0050] Specifically, the vibration absorber 10 may be magnetic and adsorbed to the desired installation position, and may also be fixed to the desired installation position by other fasteners.
