Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings.

[0034] One embodiment of this utility model is an elastic damping element, comprising an elastic unit 1 and a wire rope unit 2, such as... Figure 1 As shown, these are products or components used for vibration control, such as vibration isolators, vibration absorbers, and vibration dampers, to control the vibration of equipment. For example... Figure 2 As shown, the elastic damping element of this utility model is fixed to different external structural components on both sides.

[0035] like Figure 3 As shown, the elastic unit 1 includes a first elastic unit mounting part 11, an elastic deformation part 12, and a second elastic unit mounting part 13, which are fixedly connected in sequence. The first elastic unit mounting part 11 and the second elastic unit mounting part 13 are arranged opposite to each other.

[0036] like Figure 4 As shown, the wire rope unit 2 includes a first wire rope mounting part 21, a second wire rope mounting part 22, and a wire rope 23 that are fixedly connected. The first wire rope mounting part 21 and the second wire rope mounting part 22 are arranged parallel to each other.

[0037] The first elastic unit mounting part 11 and the second elastic unit mounting part 13 are fixedly connected to the first wire rope mounting part 21 and the second wire rope mounting part 22, respectively. The wire rope 23 is located inside the elastic deformation part 12.

[0038] Preferably, in another embodiment, both the first wire rope mounting part 21 and the second wire rope mounting part 22 are provided with wire rope fixing holes 201, and the wire rope 23 passes through the wire rope fixing holes 201 of the first wire rope mounting part 21 and the second wire rope mounting part 22 and is fixed to the first wire rope mounting part 21 and the second wire rope mounting part 22.

[0039] Preferably, in another embodiment, the first wire rope mounting portion 21 is provided with a first wire rope mounting hole 211, the second wire rope mounting portion 22 is provided with a second wire rope mounting hole 221, the first elastic unit mounting portion 11 is provided with a first elastic unit mounting interface 111, and the second elastic unit mounting portion 13 is provided with a second elastic unit mounting interface 131. The elastic element 1, the wire rope unit 2, and the first external structural member 3 are fixed by fasteners passing through the first wire rope mounting hole 211 and the first elastic unit mounting interface 111, and the elastic element 1, the wire rope unit 2, and the second external structural member 4 are fixed by fasteners passing through the second wire rope mounting hole 221 and the second elastic unit mounting interface 131. Figure 2 As shown, the first external structural component 3 and the second external structural component 4 are located on both sides of the elastic damping element of this utility model.

[0040] The elastic deformation part 12 deforms when subjected to external tension or compression and can recover when the external force is removed. It absorbs and isolates the vibration energy of the external structural member (e.g., the first external structural member 3 fixedly connected to the first elastic unit mounting part) and prevents it from being transmitted to the external structural member fixedly connected to the other side (e.g., the second external structural member 4 fixedly connected to the second elastic unit mounting part).

Both the elastic unit 1 and the wire rope unit 2 adopt a modular design, which can be flexibly configured according to the vibration of the external structural components and the mass of the elastic damping element can be easily adjusted. Therefore, the elastic damping element of this invention can conveniently and quickly adjust the quantity, material, and structure of the elastic unit 1 and the wire rope unit 2, thereby adjusting the vibration-related elasticity, damping, mass, and other properties, accurately matching the required vibration performance, and thus producing the best vibration control effect.

[0042] Specifically, preferably, such as Figure 1-3 As shown, the elastic deformation part 12 is a spring sheet, such as a U-shaped or gourd-shaped spring sheet.

[0043] Preferably, in another embodiment, the elastic deformation portion 12 is a rod-shaped structure, such as... Figure 5 As shown, the elastic damping element using this elastic unit is as follows: Figure 6 As shown.

[0044] Figure 1-2 In the illustrated embodiment, two elastic units 1 are arranged opposite each other and fixed to the same wire rope unit 1. This allows the elastic damping element to have higher stiffness, stronger elasticity, and more balanced performance compared to an elastic damping element with only one elastic unit. In another embodiment, several wire rope units 2 can also be arranged side by side and fixed to one elastic unit 1, such as... Figure 7 As shown. In another embodiment, a wire rope unit 2 can also be fixed to an elastic unit 1, as shown. Figure 8 As shown.

[0045] Preferably, in another embodiment, a plurality of spiral-shaped wire ropes 23 are threaded through the wire rope fixing holes 201 of the first wire rope mounting part 21 and the second wire rope mounting part 22, such as... Figure 9 As shown, the damping of the elastic damping element can be easily and quickly adjusted by adjusting the number and material of the wire ropes 23.

[0046] The elastic damping element of this invention can be made of different materials and has different resistance to high and low temperatures, corrosion, radiation, oxidation, aging, etc., making it suitable for applications in various environments.

[0047] The elastic damping element of this invention adjusts stiffness through an elastic unit and damping through a wire rope unit. All components adopt a modular design, which can be flexibly configured according to the vibration of the equipment. The materials and structure can be easily adjusted to adjust the vibration-related elastic, damping, mass and other properties, and accurately match the required vibration performance, thereby producing the best vibration control effect.

[0048] The elastic damping element of this invention has a simple structure and is easy to process.

[0049] The elastic damping element and vibration reduction device of this invention can be widely used in vibration control-related products or components such as vibration isolators, dynamic vibration absorbers, and vibration isolation foundations.
