[0037] See also Figure 1 and Figure 2 ,in, Figure 1 A structural schematic diagram of an electrical system 200 provided in an embodiment of the present application is illustrated; Figure 2 A structural schematic diagram of a vibration reduction device 100 provided in an embodiment of the present application is illustrated.

[0038] The embodiment of the present application provides a vibration reduction device 100, which is used for vibration reduction of an electrical device 110. The vibration reduction device includes a platform 10 and a plurality of brackets 20. The plurality of brackets 20 are arranged around the outer side of the platform 10 in the horizontal direction. Each bracket 20 includes a fixing portion 21. The fixing portion 21 extends toward the platform 10. The fixing portion 21 and the platform 10 are spaced apart from each other in the vertical direction. The vibration reduction device 100 also includes a plurality of first connection components 30. Each first connection component 30 includes two first springs 31 and a first adapter 32. The two first springs 31 are arranged at intervals in the horizontal direction. The first adapter 32 is arranged between the two first springs 31. One of the first springs 31 is connected between the platform 10 and the first adapter 32, and the other first spring 31 is connected between the fixing portion 21 and the first adapter 32.

[0039] Specifically, Figure 1 As shown, the vibration reduction device 100 includes four brackets 20, which are respectively located at the four corners of the platform 10, each bracket 20 is connected to the edge of the platform 10 through a first connecting assembly 30, the electrical device 110 is located on the side of the platform 10 facing the fixed part, each first adapter 32 is suspended below the fixed part 21 through a first spring 31, and the platform 10 is suspended below the first adapter 32 through another first spring 31. The platform 10 can swing relative to the first adapter 32, and the first adapter 32 can swing relative to the bracket 20, and the swing and the elasticity of the first spring 31 are used to reduce the vibration transmitted to the platform 10.

[0040] In other embodiments, the number of brackets 20 of the vibration reduction device 100 may be three or more than four, and the first connecting component 30 may also be connected to other positions of the platform 10. The specific number and connection position may be adjusted based on the center of gravity position of the electrical equipment 110 to keep the platform 10 in a stable state.

[0041] In the vibration reduction device 100 provided in the embodiment of the present application, the sum of the sizes of the two first springs 31 in the vertical direction is greater than the distance between the platform 10 and the fixing portion 21 .

[0042] Specifically, Figure 2 The first adapter 32 shown includes a first protrusion 321 and a second protrusion 322, the first protrusion 321 and the second protrusion 322 are spaced apart from each other in the vertical direction, the first protrusion 321 is located on the side of the second protrusion 322 facing the platform, the first protrusion 321 and the second protrusion 322 extend in the horizontal direction respectively, and the first protrusion 321 and the second protrusion 322 extend in different directions. The first protrusion 321 is connected to the fixing portion 21 through a first spring 31, and the second protrusion 322 is connected to the platform 10 through another first spring 31.

[0043] In the existing vibration reduction device, the fixed part is directly connected to the platform through a spring. Figure 2 In the vibration reduction device 100 provided, along the vertical direction, the sum of the sizes of the two first springs 31 is equal to the distance between the fixing portion 21 and the platform and twice the distance between the first protrusion 321 and the second protrusion 322. Compared with the existing vibration reduction device, the vibration reduction device 100 provided in the embodiment of the present application has a longer force transmission path, that is, the platform 10 for supporting the electrical device 110 is farther from the vibration source, and has a better vibration reduction effect.

[0044] The natural frequency of the vibration reduction device 100 provided in the embodiment of the present application matches the natural frequency of the electrical device 110. After the natural frequency of the vibration reduction device 100 matches the natural frequency of the electrical device 110, the vibration reduction device 100 can absorb the vibration of the corresponding natural frequency, reduce the vibration response of the electrical device 110 to the natural frequency, and thus reduce the damage to the electrical device 110 caused by the vibration.

[0045] In addition, since some natural frequencies of the electrical equipment 110 are relatively high, when adjusting the existing vibration reduction device, the spring between the fixed part and the platform needs to have a longer size so that the natural frequency of the vibration reduction device matches the natural frequency of the electrical equipment 110. This makes the existing vibration reduction device require a larger space to accommodate the swing of the platform relative to the bracket.

[0046] The first adapter 32 and the two first springs 31 of the vibration reduction device 100 provided in the embodiment of the present application cooperate with each other to extend the length of the cycloid of the simple pendulum, so that the size of the vibration reduction device 100 in the vertical direction is smaller, saving the space occupied by the vibration reduction device 100.

[0047] The embodiment of the present application also provides an electrical system 200, which includes an electrical device 110 and a vibration reduction device 100, wherein the platform 10 of the vibration reduction device 100 is used to carry the electrical device 110. The electrical system 200 of the present application has a better vibration reduction effect because it adopts the vibration reduction device 100, which is conducive to extending the service life of the electrical device 110.

[0048] It should be pointed out that the vibration reduction device 100 provided in the present application can be applied not only to the electrical system 200, but also to other structures and systems that require vibration reduction. The vibration reduction device 100 of the present application is also applicable, and has a better vibration reduction effect and occupies a smaller space.

[0049] In one embodiment, the first adapter 32 includes a first protrusion 321 and a second protrusion 322 spaced apart from each other in the vertical direction, the first protrusion 321 and the second protrusion 322 are located between the platform 10 and the fixed portion 21 in the vertical direction, the first protrusion 321 is located on the side of the second protrusion 322 facing the platform 10, the first protrusion 321 is used to be connected to the fixed portion 21 through a first spring 31, and the second protrusion 322 is used to be fixedly connected to the platform 10 through another first spring 31.

[0050] In one embodiment, if Figure 2 As shown, the first adapter 32 includes a first protrusion 321 and a second protrusion 322. The first protrusion 321 located relatively below in the vertical direction is used to connect to the fixing portion 21 through a first spring 31, and the second protrusion 322 located relatively above in the vertical direction is used to connect to the platform 10 through another first spring 31, so that the sum of the sizes of the two first springs 31 in the vertical direction is greater than the distance between the fixing portion 21 and the platform 10, that is, the first connecting component 30 has a longer force transmission path, and the natural frequency of the vibration reduction device 100 has a larger adjustable range.

[0051] See also Figure 3 and Figure 4 ,in, Figure 3 Another structural schematic diagram of an electrical system 200 provided in an embodiment of the present application is illustrated; Figure 4 Another structural schematic diagram of a vibration reduction device 100 provided in an embodiment of the present application is illustrated from a viewing angle.

[0052] In one embodiment, if Figure 3 and Figure 4 As shown, the first adapter 32 includes two adapter sub-components 324 and a sub-spring 323, one adapter sub-component 324 includes a first protrusion 321 and a third protrusion 3241, and the other adapter sub-component 324 includes a second protrusion 322 and a fourth protrusion 3242, the third protrusion 3241 and the fourth protrusion 3242 are spaced apart from each other in the vertical direction, and the third protrusion 3241 is located on the side of the fourth protrusion 3242 facing the fixing portion 21. The fixing portion 21 is connected to the first protrusion 321 of one adapter sub-component 324 through a first spring 31, the third protrusion 3241 of one adapter sub-component 324 is connected to the fourth protrusion 3242 of the other adapter sub-component 324 through the sub-spring 323, and the second protrusion 322 of the other adapter sub-component 324 is connected to the platform 10 through another first spring 31.

[0053] Understandably, compared to Figure 1 and Figure 2 The embodiments provided are Figure 3 and Figure 4In the provided embodiment, the first connecting component 30 has a longer force transmission path, and the vibration reduction effect of the vibration reduction device 100 is better; at the same time, the natural frequency of the vibration reduction device 100 is also higher, and it can be applied to vibration reduction of electrical equipment 110 with a higher natural frequency.

[0054] In one embodiment, the first adapter 32 includes a plurality of adapter sub-components 324 and a plurality of sub-springs 323, wherein the plurality of sub-springs 323 are arranged at intervals in the horizontal direction, a pair of ends of two adjacent sub-springs 323 are connected by a adapter sub-component 324, and a distance between the other pair of ends in the vertical direction is smaller than the sum of the sizes of the two adjacent sub-springs 323, and the two adapter sub-components 324 located at the two ends are used to respectively connect the first protrusion 321 and the second protrusion 322.

[0055] See also Figure 5 A partial structural diagram of a vibration reduction device 100 provided in one embodiment of the present application is shown.

[0056] In one embodiment, if Figure 5 As shown, the first adapter component 32 includes three adapter sub-components 324 and two sub-springs 323, and two adjacent adapter sub-components 324 include a pair of third protrusions 3241 and a fourth protrusion 3242, the third protrusion 3241 and the fourth protrusion 3242 are spaced apart from each other in the vertical direction, and the third protrusion 3241 is located on the side of the fourth protrusion 3242 toward the fixed portion 21, and each sub-spring 323 is connected between a pair of third protrusions 3241 and the fourth protrusion 3242.

[0057] Understandably, compared to Figure 1 and Figure 2 ,as well as Figure 3 and Figure 4 The examples provided, Figure 5 In the provided embodiment, the force transmission path of the first connecting component 30 is further increased, and the vibration reduction effect of the vibration reduction device 100 is further improved; at the same time, the natural frequency of the vibration reduction device 100 is also higher, and can be used for vibration reduction of electrical equipment 110 with a higher natural frequency.

[0058] It should be noted that the number of adapter sub-components 324 and sub-springs 323 included in the first adapter 32 is not limited to the settings in the embodiment, and the specific number can be set based on the required vibration reduction effect and the natural frequency of the electrical device 110.

[0059] See also Figure 6 Another structural schematic diagram of another viewing angle of the vibration reduction device 100 provided in one embodiment of the present application is shown.

[0060] In one embodiment, if Figure 6 As shown, the first adapter 32 includes two adapter sub-components 324. Figure 3 and Figure 4 The fixing part 21 is connected to the first protrusion 321 of an adapter sub-component 324 through a first spring 31, the third protrusion 3241 of an adapter sub-component 324 is connected to the fourth protrusion 3242 of another adapter sub-component 324 through a sub-spring 323, and the second protrusion 322 of another adapter sub-component 324 is connected to the platform 10 through another first spring 31. The arrangement direction of one first spring 31 and the sub-spring 323 and the arrangement direction of another first spring 31 and the sub-spring 323 both intersect with the extension direction of the fixing part 21, reducing the size of the first adapter 32 along the extension direction of the fixing part 21, so that the platform 10 surrounded by multiple fixing parts 21 can have a larger horizontal space, and can thus accommodate larger electrical equipment 110.

[0061] In one embodiment, the first adapter 32 includes a plurality of sub-springs 323, and the arrangement direction of two adjacent sub-springs 323 intersects with the extension direction of the fixing portion 21. The arrangement direction of two adjacent sub-springs 323 intersects with the extension direction of the fixing portion 21, further reducing the size of the first adapter 32 along the extension direction of the fixing portion 21, thereby allowing the platform 10 surrounded by the plurality of fixing portions 21 to have a larger horizontal space, thereby being able to accommodate a larger electrical device 110.

[0062] In one embodiment, if Figure 6 As shown, the arrangement direction of the two first springs 31 intersects with the extension direction of the fixing portion 21, reducing the size of the first connecting component 30 along the extension direction of the fixing portion 21, and also allowing the platform 10 surrounded by multiple fixing portions 21 to have a larger horizontal space, thereby being able to accommodate larger electrical equipment 110.

[0063] It should be pointed out that in Figure 5 In the provided vibration reduction device 100, the extension direction of the fixing portion 21 is perpendicular to the paper surface, and the arrangement direction of two adjacent sub-springs 323 and the arrangement direction of the two first springs 31 are both parallel to the paper surface, that is, the extension direction of the fixing portion 21 is perpendicular to the arrangement direction of the two adjacent sub-springs 323 and the arrangement direction of the two first springs 31, respectively.

[0064] In one embodiment, along the vertical direction, the size of the first spring 31 connected between the platform 10 and the first adapter 32 is smaller than the size of the first spring 31 connected between the fixing portion 21 and the first adapter 32. That is, the size of the first spring 31 with a shorter force transmission path between the electrical device 110 is shorter, so as to reduce the swing amplitude of the platform 10 relative to the bracket 20.

[0065] In one embodiment, along the vertical direction, the stiffness of the first spring 31 connected between the platform 10 and the first adapter 32 is greater than the stiffness of the first spring 31 connected between the fixing portion 21 and the first adapter 32. That is, the first spring 31 with a shorter force transmission path with the electrical device 110 has a larger stiffness, which is used to reduce the deformation of the first spring 31, and can also reduce the swing amplitude of the platform 10 relative to the bracket 20.

[0066] In one embodiment, the vibration reduction device 100 includes a plurality of second connection components 40, each of which extends in a horizontal direction, wherein: a second connection component 40 is elastically connected between two first adapters 32; or a second connection component 40 is elastically connected between a first adapter 32 and a body of a bracket 20.

[0067] See also Figure 7 A partial structural diagram of a vibration reduction device 100 provided in an embodiment of the present application having a second connecting assembly 40 is shown.

[0068] In one embodiment, if Figure 7 As shown, a second connecting component 40 is provided between a first adapter 32 and a main body of a bracket 20, and the second connecting component 40 includes a second adapter 42 and two second springs 41. A second spring 41, a second adapter 42 and another second spring 41 are arranged and connected in sequence along the horizontal direction, and the two opposite ends of the two second springs 41 are respectively connected to the first adapter 32 and the main body of the bracket 20, so as to limit the horizontal displacement of the platform 10 relative to the bracket 20 during the swinging process, reduce the swinging amplitude of the platform 10, and thereby reduce the horizontal vibration of the electrical equipment 110.

[0069] Understandably, in Figure 7 In the vibration reduction device 100 provided, the weight of the electrical device 110 will change the height of the platform 10, thereby affecting the height of the first adapter 32, causing the second spring 41 to tilt, thereby reducing the limiting effect of the second connecting component 40 on the horizontal displacement of the platform.

[0070] See also Figure 8 Another partial structural schematic diagram of a vibration reduction device 100 provided in an embodiment of the present application having a second connecting assembly 40 is shown.

The sliding member 22 slides in the vertical direction relative to the body of the bracket 20. The two opposite ends of the two second springs 41 of the second connecting component 40 are respectively connected to the first adapter 32 and the sliding member 22. By adjusting the height of the sliding member 22 so that the extension direction of the two second springs 41 is parallel to the horizontal direction, the limiting effect of the second connecting component 40 on the horizontal direction of the platform is ensured.

[0072] In one embodiment, the second connecting component 40 includes a second adapter 42 and two second springs 41, the two second springs 41 are arranged at intervals in the vertical direction, and the second adapter 42 is connected between the two second springs 41, wherein: along the extension direction of the fixing portion 21, the sum of the sizes of the two second springs 41 is greater than the distance between a first adapter 32 and a body of a bracket 20, so that the second connecting component 40 has a longer force transmission path, thereby improving the vibration reduction ability of the vibration reduction device 100 to horizontal vibration.
