The first elastic component and the second elastic component are respectively arranged on both sides of the connecting plate. The first elastic component is connected between the connecting plate and the platform, and the second elastic component is used to support the connecting plate; the first elastic component includes a first natural frequency, the second elastic component includes a second natural frequency, and the first elastic component, the connecting plate and the second elastic component are connected to form a whole that includes a third natural frequency. The first natural frequency, the second natural frequency and the third natural frequency are used to match the three natural frequencies of the electrical equipment respectively.
[0005] The second elastic component of the vibration reduction device of the present application is used to support the connecting plate, the first elastic component is connected between the platform and the connecting plate, and the first elastic component and the second elastic component are used to separate the electrical equipment from the vibration source to reduce the vibration of the electrical equipment.
[0006] The first elastic component of the present application corresponds to the first natural frequency, the second elastic component corresponds to the second natural frequency, and the whole formed by the first elastic component, the connecting plate and the second elastic component corresponds to the third natural frequency. The first natural frequency, the second natural frequency and the third natural frequency correspond to the three natural frequencies of the electrical device respectively. When the vibration frequency is close to the three natural frequencies, the vibration reduction device will absorb the vibration energy to reduce the vibration and avoid the resonance of the electrical device causing damage to the electrical device.

[0008] In this embodiment, the first elastic component includes a plurality of first elastic members, each of which has a different natural frequency, so that the plurality of first elastic members can absorb vibration energy of multiple frequencies to prevent the electrical device from resonating. The second elastic component includes a plurality of second elastic members, each of which has a different natural frequency, so that the plurality of second elastic members can also absorb vibration energy of multiple frequencies to prevent the electrical device from resonating.
[0009] In one embodiment, each first elastic member includes a first connecting sub-member and two first springs, one first spring, the first connecting sub-member and another first spring are arranged and connected in sequence along the vertical direction, and the masses of the multiple first connecting sub-members are different; and / or each second elastic member includes a second connecting sub-member and two second springs, one second spring, the second connecting sub-member and another second spring are arranged and connected in sequence along the vertical direction, and the masses of the multiple second connecting sub-members are different.
[0010] In this embodiment, the first elastic member includes a first connecting member and two first springs. The first connecting member cooperates with the two first springs so that the first connecting member can reciprocate in the vertical direction when the vibration reduction device is vibrated, thereby absorbing the vibration of the corresponding frequency of the first elastic member and preventing the vibration of this frequency from affecting the electrical equipment.
[0011] Correspondingly, the second elastic member includes a second connecting member and two second springs. The second connecting member cooperates with the two second springs so that the second connecting member can also reciprocate in the vertical direction when the vibration reduction device is vibrated, thereby absorbing the vibration of the corresponding frequency of the second elastic member and preventing the vibration of this frequency from affecting the electrical equipment.
[0012] In one embodiment, along the direction toward the geometric center of the platform, the masses of the plurality of first connection sub-components increase one by one; and / or along the direction toward the geometric center of the platform, the masses of the plurality of second connection sub-components increase one by one.
[0013] In this embodiment, the masses of multiple first connecting sub-components are increased one by one, so that the natural frequencies of each first connecting sub-component along the direction toward the geometric center of the platform are different, which are used to absorb vibrations of different frequencies; at the same time, the mass of the first elastic component is concentrated in the middle of the platform, that is, the projection of the center of mass of the first elastic component on the platform is located in the middle of the platform, thereby ensuring the stability of the platform.
[0014] Correspondingly, the masses of the multiple second connecting sub-components are increased one by one, so that the natural frequencies of the second connecting sub-components along the direction toward the geometric center of the platform are different, which are used to absorb vibrations of different frequencies; at the same time, the mass of the second elastic component is concentrated in the middle of the platform, that is, the projection of the center of mass of the second elastic component on the platform is located in the middle of the platform, which can also ensure the stability of the platform.
[0015] In one embodiment, the sum of the masses of the plurality of first connecting components is less than the sum of the masses of the plurality of second connecting components.
[0016] In this embodiment, the overall mass of the first elastic component is smaller than the overall mass of the second elastic component, so that the height of the center of mass of the whole formed by the first elastic component, the connecting plate and the second elastic component is relatively low, ensuring the stability of the platform and facilitating the stability of the vibration reduction device.
[0017] In one embodiment, the connecting plate includes a plurality of connecting sub-plates and a plurality of third elastic members, the plurality of connecting sub-plates are arranged at intervals in the vertical direction, two adjacent connecting sub-plates are connected by a plurality of third elastic members, the plurality of third elastic members between two adjacent connecting sub-plates are spaced apart from each other in the horizontal direction, and the two connecting sub-plates located at both ends are used to be respectively connected to the first elastic component and the second elastic component.
[0018] In this embodiment, two adjacent connecting sub-plates are connected by a plurality of third elastic members, and the plurality of third elastic members are used to separate the two adjacent connecting sub-plates, reduce the transmission of vibration energy between the two adjacent connecting sub-plates, and thus improve the vibration reduction effect of the vibration reduction device. In addition, a plurality of third elastic members are respectively connected to two opposite sides of some connecting sub-plates in the vertical direction, so that the connecting sub-plates can also reciprocate in the vertical direction when the vibration reduction device is vibrated, so as to absorb the vibration of the corresponding frequency and prevent the vibration of the frequency from affecting the electrical equipment.
[0019] In one embodiment, the natural frequencies of the third elastic members between two adjacent connecting sub-plates are different.
[0020] In this embodiment, the natural frequencies of the third elastic members are different, so that the plurality of third elastic members connected between two connecting sub-boards can also absorb vibration energy of multiple frequencies, thereby preventing the electrical device from resonating.
[0021] In one embodiment, the masses of the plurality of connection sub-boards increase one by one in a direction away from the electrical device.
[0022] In this embodiment, the farther the connecting sub-board is from the electrical equipment, the greater its mass is, so that the height of the center of mass of the connecting plate is lower, which ensures the stability of the platform and is conducive to the stability of the vibration reduction device.
[0023] In one embodiment, the first elastic component and the second elastic component both include a damping member, and the damping member is used to provide a damping force in a vertical direction.
[0024] In this embodiment, the damping force in the vertical direction is provided by the damping member, so as to reduce the vibration transmitted to the platform through the first elastic component and the second elastic component, thereby improving the vibration reduction capacity of the vibration reduction device.
[0025] In a second aspect, an embodiment of the present application further provides an electrical system, comprising the above-mentioned vibration reduction device, wherein the platform of the vibration reduction device is used to carry electrical equipment.

[0037] The vibration reduction device 100 provided in the embodiment of the present application is used to carry the electrical equipment 110. The vibration reduction device 100 includes a platform 10, a connecting plate 20, a first elastic component 30 and a second elastic component 40. The connecting plate 20, the first elastic component 30 and the second elastic component 40 are all located on the side of the platform 10 away from the electrical equipment 110. The first elastic component 30 and the second elastic component 40 are arranged on both sides of the connecting plate 20. The first elastic component 30 is connected between the connecting plate 20 and the platform 10, and the second elastic component 40 is used to support the connecting plate 20.
[0038] Specifically, Figure 1 and Figure 2 As shown, the platform 10, the first elastic component 30, the connecting plate 20 and the second elastic component 40 are arranged and connected in sequence from top to bottom in the vertical direction, and the side of the platform 10 away from the first elastic component 30 is used to carry the electrical equipment 110. The first elastic component 30 includes a plurality of first elastic members 31 and a plurality of third springs 32, the plurality of first elastic members 31 are spaced apart in the horizontal direction, the plurality of third springs 32 are arranged around the outer sides of the plurality of first elastic members 31, and the two ends of each third spring 32 are respectively connected to the connecting plate 20 and the platform 10, so as to ensure the stability of the platform 10 and prevent the platform 10 from tipping over due to the uneven distribution of the plurality of first elastic members 31 in the first elastic component 30.
[0039] Similarly, in Figure 1 and Figure 2In the provided vibration reduction device 100, the second elastic component 40 includes a plurality of second elastic members 41 and a plurality of fourth springs 42. The plurality of second elastic members 41 are spaced apart in the horizontal direction, and the plurality of fourth springs 42 are arranged around the outside of the plurality of second elastic members 41. Each fourth spring 42 is used to support the connecting plate, so as to ensure the stability of the connecting plate 20 and avoid the connecting plate 20 from tipping over due to uneven distribution of the plurality of second elastic members 41 in the second elastic component 40, thereby affecting the stability of the platform 10.
[0040] exist Figure 1 and Figure 2 In the provided vibration reduction device 100, the first elastic component 30 includes three first elastic members 31 and four third springs 32. The three first elastic members 31 are distributed in the middle of the platform 10, and the four third springs 32 are respectively located at the four corners of the platform 10 to ensure the stability of the platform 10.
[0041] In some embodiments, the number of the first elastic member 31 and the third spring 32 of the first elastic component 30 can be set based on the weight of the electrical device 110, and the position of the first elastic member 31 and the third spring 32 of the first elastic component 30 can be set based on the relative position of the platform 10 and the connecting plate 20 to ensure the stability of the platform 10, which is conducive to the platform 10 carrying the electrical device 110.
[0042] In other embodiments, the number of the second elastic member 41 and the fourth spring 42 of the second elastic component 40 can be set based on the weight of the electrical equipment 110, the platform 10 and the connecting plate 20, and the position of the second elastic member 41 and the fourth spring 42 of the second elastic component 40 can be set based on the position of the connecting plate 20 to ensure the stability of the connecting plate 20, which is beneficial for the platform 10 to carry the electrical equipment 110.
[0043] The first elastic component 30 of the vibration reduction device 100 provided in the embodiment of the present application includes a first natural frequency, the second elastic component 40 includes a second natural frequency, and the whole formed by connecting the first elastic component 30, the connecting plate 20 and the second elastic component 40 includes a third natural frequency. The first natural frequency, the second natural frequency and the third natural frequency are used to match the three natural frequencies of the electrical equipment 110 respectively.
[0044] It can be understood that when the vibration frequency of the vibration source matches any one of the three natural frequencies mentioned above, the vibration energy will be absorbed by the first elastic component 30, the second elastic component 40 and the whole formed by the first elastic component 30, the connecting plate 20 and the second elastic component 40 during the process of being transmitted to the platform 10, thereby reducing the vibration of this frequency to which the electrical equipment 110 is subjected.
[0045] The first natural frequency, the second natural frequency and the third natural frequency respectively match the three natural frequencies of the electrical device 110. The vibration energy of the corresponding frequencies is absorbed by the vibration reduction device 100 during the process of being transmitted to the electrical device 110, thereby weakening the vibration of the corresponding frequencies and avoiding resonance of the electrical device 110 and causing damage to the electrical device 110.
[0046] 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.
[0047] 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.
[0048] In one embodiment, the first elastic component 30 includes a plurality of first elastic members 31 spaced apart in a horizontal direction, and each first elastic member 31 has a different natural frequency, so that the plurality of first elastic members 31 can absorb vibration energy of multiple frequencies to avoid resonance of the electrical equipment 110.
[0049] See also Figure 3 A schematic structural diagram of a first elastic member 31 provided in an embodiment of the present application is shown.
[0050] In one embodiment, if Figure 3 As shown, each first elastic member 31 includes a first connecting member 312 and two first springs 311. One first spring 311, the first connecting member 312 and the other first spring 311 are arranged and connected in sequence along the vertical direction. The masses of the plurality of first connecting members 312 are different. The first connecting member 312 cooperates with the two first springs 311 so that the first connecting member 312 can reciprocate along the vertical direction when the vibration reduction device 100 is vibrated, thereby absorbing the vibration of the corresponding frequency of the first elastic member 31 to prevent the vibration of the frequency from affecting the electrical equipment 110.
[0051] See also Figure 4 and Figure 5 ,in, Figure 4 A schematic structural diagram of another viewing angle of a vibration reduction device 100 provided in an embodiment of the present application is shown; Figure 5 A structural schematic diagram of a vibration reduction device 100 provided in an embodiment of the present application from another perspective is shown.
[0052] In one embodiment, if Figure 4 As shown, the first elastic component 30 includes three first elastic members 31, each of which includes a first connecting member 312 and two first springs 311, and the two first springs 311 have two opposite ends connected to the first connecting member 312, and two opposite ends connected to the connecting plate 20 and the platform 10. Figure 5 , the three first elastic members 31 are arranged in sequence in the horizontal direction, wherein the mass of the first connecting sub-member 312 of the first elastic member 31 in the middle is greater than the mass of the first connecting sub-members 312 of the two first elastic members 31 at both ends.
[0053] It can be understood that the different masses of the first connecting member 312 result in different natural frequencies of the first elastic member 31. Figure 4 and Figure 5 In the vibration reduction device 100 provided, the three first elastic members 31 respectively include two natural frequencies, so that the three first elastic members 31 can absorb the vibration energy of the two frequencies, thereby reducing the vibration transmitted to the electrical device 110 .
[0054] Similarly, in one embodiment, each second elastic member 41 includes a second connecting sub-member 412 and two second springs 411, and one second spring 411, a second connecting sub-member 412 and another second spring 411 are arranged and connected in sequence along the vertical direction, and the masses of the plurality of second connecting sub-members 412 are different, so that the plurality of second elastic members 41 can absorb vibration energy of multiple frequencies to avoid resonance of the electrical equipment 110.

One second spring 411, the second connecting sub-member 412 and another second spring 411 are arranged and connected in sequence along the vertical direction. The masses of the plurality of second connecting sub-members 412 are different, so that the second connecting sub-members 412 can also reciprocate along the vertical direction when the vibration reduction device 100 is vibrated, thereby absorbing the vibration of the corresponding frequency of the second elastic member 41 to prevent the vibration of this frequency from affecting the electrical equipment 110.
[0056] In one embodiment, if Figure 4As shown, the second elastic component 40 includes three second elastic members 41, each of which includes a second connecting member 412 and two second springs 411, the two second springs 411 have two ends facing each other connected to the two opposite sides of the second connecting member 412, and two ends facing each other connected to the connecting plate 20 and the foundation. Similarly, the three second elastic members 41 are arranged in sequence in the horizontal direction, wherein the mass of the second connecting member 412 of the second elastic member 41 in the middle is greater than the mass of the second connecting member 412 of the two second elastic members 41 at the two ends.
[0057] In one embodiment, the masses of the plurality of first connecting sub-components 312 are increased one by one along the direction toward the geometric center of the platform 10, so that the natural frequencies of the respective first connecting sub-components 312 along the direction toward the geometric center of the platform 10 are different, so as to absorb vibrations of different frequencies.
[0058] In one embodiment, if Figure 5 As shown, the first elastic component 30 includes three first elastic members 31, one first elastic member 31 is located in the middle of the platform 10 along the horizontal direction, and the other two first elastic members 31 are arranged on both sides. The mass of the first connecting sub-member 312 of the first elastic member 31 located in the middle is greater than the mass of the first connecting sub-member 312 of the first elastic members 31 on both sides, that is, the projection of the center of mass of the first elastic component 30 on the platform 10 is located in the middle of the platform 10, thereby ensuring the stability of the platform 10.
[0059] In other embodiments, the plurality of first elastic members 31 are centrally symmetric about the geometric center of the platform 10 , and the masses of the plurality of first connecting sub-members 312 increase one by one along the direction toward the geometric center of the platform 10 , thereby further improving the stability of the platform 10 .
[0060] Similarly, in one embodiment, the masses of the plurality of second connecting sub-components 412 are gradually increased along the direction toward the geometric center of the platform 10, so that the natural frequencies of the respective second connecting sub-components 412 along the direction toward the geometric center of the platform 10 are different, so as to absorb vibrations of different frequencies.
[0061] In one embodiment, if Figure 4 As shown, the second elastic component 40 includes a second elastic member 41 located in the middle of the platform 10 along the horizontal direction, and the other two second elastic members 41 are arranged on both sides. The mass of the second connecting sub-member 412 of the second elastic member 41 located in the middle is greater than the mass of the second connecting sub-members 412 of the second elastic members 41 on both sides, that is, the projection of the center of mass of the second elastic component 40 on the platform 10 is located in the middle of the platform 10, thereby ensuring the stability of the platform 10.
[0062] In other embodiments, the plurality of second elastic members 41 are centrally symmetrical about the geometric center of the platform 10 , and the masses of the plurality of second connecting sub-members 412 increase one by one along the direction toward the geometric center of the platform 10 , thereby further improving the stability of the platform 10 .
[0063] In one embodiment, the sum of the masses of the plurality of first connecting sub-components 312 is less than the sum of the masses of the plurality of second connecting sub-components 412. That is, the overall mass of the first elastic component 30 is less than the overall mass of the second elastic component 40, so that the height of the center of mass of the whole formed by the first elastic component 30, the connecting plate 20 and the second elastic component 40 is relatively low, which ensures the stability of the platform 10 and is conducive to the stability of the vibration reduction device 100.
[0064] In one embodiment, if Figure 2 and Figure 5 As shown, the first elastic component 30 includes a plurality of third springs 32, which are arranged around the outside of the plurality of first elastic members 31 and are spaced apart from the plurality of first elastic members 31 in the horizontal direction. Due to the first connecting sub-member 312 inside the first elastic member 31, the allowable elastic variation range of the first elastic member 31 in the vertical direction is reduced. By arranging a plurality of third springs 32 on the outside of the plurality of first elastic members 31, the overall stiffness of the first elastic component 30 can be increased, which is conducive to maintaining the stability of the platform 10.
[0065] Similarly, in one embodiment, if Figure 2 As shown, the second elastic component 40 includes a plurality of fourth springs 42, which are arranged around the outside of the plurality of second elastic members 41 and are spaced apart from the plurality of second elastic members 41 in the horizontal direction. Due to the second connecting sub-members 412 inside the second elastic member 41, the allowable elastic variation range of the second elastic member 41 in the vertical direction is reduced. By arranging a plurality of fourth springs 42 on the outside of the plurality of second elastic members 41, the overall stiffness of the second elastic component 40 can be increased, which is conducive to maintaining the stability of the platform 10.

The plurality of third elastic members 221 are located between the two connecting sub-plates 21, and opposite ends of each third elastic member 221 in the vertical direction are respectively connected to the two connecting sub-plates 21 to separate the two connecting sub-plates 21, reduce the transmission of vibration energy between the two connecting sub-plates 21, and thereby improve the vibration reduction effect of the vibration reduction device 100.
[0067] See also Figure 6A schematic structural diagram of a connecting plate 20 provided in an embodiment of the present application is shown.
[0068] In one embodiment, if Figure 6 As shown, each third elastic member 221 includes a spring, a mass block and another spring arranged in sequence along the vertical direction. When the vibration reduction device 100 is vibrated, the mass block can also reciprocate along the vertical direction, thereby absorbing the vibration of the corresponding frequency of the second elastic member 41 to prevent the vibration of this frequency from affecting the electrical equipment 110.
[0069] In one embodiment, if Figure 6 As shown, a third elastic member 221 is located in the middle of the platform 10 along the horizontal direction, and the other two third elastic members 221 are arranged on both sides. The mass of the mass block of the third elastic member 221 located in the middle is greater than the mass of the mass blocks of the third elastic members 221 on both sides, that is, the projection of the center of mass of the whole formed by multiple third elastic members 221 on the platform 10 is located in the middle of the platform 10, ensuring the stability of the platform 10.
[0070] exist Figure 6 In the vibration reduction device 100 provided, the masses of the mass blocks are different, so that the natural frequencies of the third elastic members 221 are different, that is, the multiple third elastic members 221 respectively include multiple natural frequencies, so that the multiple third elastic members 221 can absorb the vibration energy of these multiple frequencies, thereby weakening the vibration transmitted to the electrical equipment 110.
[0071] In one embodiment, the connecting plate 20 includes a plurality of connecting sub-plates 21 and a plurality of third elastic members 221, the plurality of connecting sub-plates 21 are arranged at intervals in the vertical direction, two adjacent connecting sub-plates 21 are connected by the plurality of third elastic members 221, the plurality of third elastic members 221 between two adjacent connecting sub-plates 21 are spaced from each other in the horizontal direction, and the two connecting sub-plates 21 located at both ends are used to be respectively connected to the first elastic component 30 and the second elastic component 40. The two adjacent connecting sub-plates 21 are connected by the plurality of third elastic members 221, and the plurality of third elastic members 221 are used to separate the two adjacent connecting sub-plates 21, reduce the transmission of vibration energy between the two adjacent connecting sub-plates 21, and thereby improve the vibration reduction effect of the vibration reduction device 100.
[0072] In addition, a portion of the connecting sub-plates 21 are respectively connected to two opposite sides in the vertical direction with a plurality of third elastic members 221 , so that the connecting sub-plates 21 can also reciprocate in the vertical direction when the vibration reduction device 100 is vibrated, thereby absorbing the vibration of the corresponding frequency and preventing the vibration of this frequency from affecting the electrical equipment 110 .
[0073] See also Figure 7 Another structural schematic diagram of the connecting plate 20 provided in one embodiment of the present application is shown.
[0074] In one embodiment, if Figure 7 As shown, the connecting plate 20 includes four connecting sub-plates 21 and a plurality of third elastic members 221. The four connecting sub-plates 21 are arranged at intervals in the vertical direction.

[0075] In one embodiment, if Figure 6 and Figure 7 As shown, the connecting plate 20 further includes a plurality of fifth springs 222, which are arranged around the outer sides of the plurality of third elastic members 221 and are spaced apart from the plurality of third elastic members 221 in the horizontal direction.
