[0002] The geometric dimensions of large-scale structures, such as high-rise and super-high-rise structures and long-span spatial structures, are rapidly increasing. In recent years, large-scale civil structures have become increasingly common in engineering practice. To ensure the safety and functional continuity of these structures under the dynamic forces of disasters such as earthquakes and strong winds, high-performance energy dissipation and vibration reduction technologies are being employed in the structural design of large buildings.

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments and accompanying drawings specifically illustrate the axial deformation conversion damping and energy dissipation mechanism of the present invention.
[0022] <Example>
[0023] Figure 1 It is a structural schematic diagram of the axial deformation conversion damping energy dissipation mechanism in an embodiment of the present invention.
[0024] Figure 2 It is a side view of the axial deformation conversion damping and energy dissipation mechanism in an embodiment of the present invention.
[0025] like Figure 1 and Figure 2 As shown, the axial deformation conversion damping and energy dissipation mechanism 100 is arranged on a building structure, and includes two groups of connecting rod units 10 , two anchor plate groups 20 and a damping part 30 .
[0026] In this embodiment, each connecting rod unit 10 includes three connecting rods 11. Each of the six connecting rods 11 has a first rotation hole and a second rotation hole at each end. In this embodiment, the first rotation hole can be connected to the damping unit 30, and the second rotation hole can be connected to the anchor plate assembly 20. In this embodiment, the length of the connecting rods 11 is adapted to the distance between the walls of the building structure. For large-scale buildings, increasing the length of the connecting rods 11 can broaden the application range of the axial deformation conversion damping and energy dissipation mechanism 100 provided by the present invention.
[0027] Figure 3 In the embodiment of the present invention Figure 1 A partial enlarged view of part A.
[0028] like Figure 3 As shown, two anchor plate groups 20 are rotatably arranged at one end of two groups of connecting rod units 10, which can connect the two groups of connecting rod units to the building structure. In this embodiment, each anchor plate group 20 includes an anchor plate 21 and three connecting plates 22.
[0029] Anchor plate 21 is attached to the building structure. In this embodiment, the side of anchor plate 21 closest to the building structure has multiple protrusions 211. These protrusions 211 increase the surface roughness of anchor plate 21, thereby strengthening the connection between anchor plate 21 and the building structure. In this embodiment, there are six protrusions 211, arranged in groups of two, with each group of protrusions 211 spaced evenly apart on the surface of anchor plate 21.
[0030] Each of the three connecting plates 22 is vertically disposed on a side of the anchor plate 21 opposite the plurality of protrusions 211. A third through-hole is defined in each connecting plate 22, which mates with the second rotation hole. Bolts 1 mate with the second rotation hole and pass through the second rotation hole and the third through-hole, thereby rotatably connecting the connecting plate 22 to the connecting rod 11. In this embodiment, the three connecting plates 22 are evenly distributed on the anchor plate 21, and the angle between each two connecting plates 22 is 120°.
[0031] Figure 4 In the embodiment of the present invention Figure 1 A partial enlarged view of part B;
[0032] like Figure 4As shown, the damping part 30 includes a fixing unit 31 and an energy dissipation unit 32. The fixing unit 31 can be connected to the other end of the two groups of connecting rod units 10 away from the anchor plate group 20. The energy dissipation unit 32 is arranged on the fixing unit 31 and can provide damping for the building structure.
[0033] In this embodiment, the fixing unit 31 includes three cross-hinged beams 311, each of which has two first flanges 3111 and two second flanges 3112. Each first flange 3111 is perpendicular to two second flanges 3112. The first flange 3111 can be connected to the energy dissipation unit 32, and the second flange 3112 can be connected to the connecting rod unit. In this embodiment, the first flange 3111 is provided with a first through hole, and the second flange 3112 is provided with a second through hole.
[0034] In this embodiment, the energy dissipation unit 32 includes three dampers 321. Both ends of the dampers 321 are provided with connection holes that are compatible with the first through holes. The dampers 321 are inserted into the first through holes and the connection holes by bolts 1 that are compatible with the first through holes, thereby being rotatably connected to the first flanges 3111 of the two cross-hinged beams 311. In this embodiment, the three dampers 321 and the three cross-hinged beams 311 are connected to form a triangle. The dampers 321 are located on the three sides of the triangle, and the cross-hinged beams are located at the three endpoints of the triangle, thereby enhancing the structural stability of the axial deformation conversion damping energy dissipation mechanism 100. In this embodiment, the dampers are oil dampers. In actual applications, other types of dampers 321 can also be selected as needed.
[0035] In this embodiment, the first rotating hole at one end of the connecting rod 11 is adapted to the second through hole, and the six connecting rods 11 are all passed through the second through hole and the first rotating hole by bolts adapted to the second through hole, thereby being rotatably connected to the six second flanges 3112.
[0036] Figure 5 It is a schematic diagram of the axial deformation conversion damping energy dissipation mechanism in an embodiment of the present invention undergoing axial deformation.
[0037] like Figure 5As shown, the axial deformation conversion damping and energy dissipation mechanism 100 provided by the present invention is fixed between the walls of a building structure through an anchor plate group 20. When the building structure is affected by disasters such as earthquakes and strong winds, additional loads are applied between the walls, causing relative displacement. The additional load is transmitted to the dampers 321 of the axial deformation conversion damping and energy dissipation mechanism 100. The dampers 321 extend or contract, causing the sides of the triangle formed by the three dampers 321 and the three cross-hinged beams 311 to lengthen, driving the connecting rod 11 to rotate and achieve axial deformation, thereby adapting the length of the connecting rod unit 10 to the relative displacement between the walls, and the additional load is dissipated by the dampers 321. Therefore, the axial deformation conversion damping and energy dissipation mechanism 100 provided by the present invention can convert the axial relative displacement and velocity between the two anchor plate groups into the piston stroke and velocity of the damper 321 through the axial deformation of the connecting rod 11, thereby achieving the purpose of amplifying the stroke of the damper 321 and improving the structural additional damping of the damper 321.
