[0022] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] like Figure 1 and Figure 2As shown, this embodiment provides a self-resetting viscous damper, including two groups of rotating components, two groups of transmission components, an energy-absorbing component and a self-resetting component. The upper ends of the two groups of rotating components are connected to the structural top beam 14, and the two groups of rotating components are located on both sides above the window hole 17, and the spacing between them is greater than the width of the window hole 17. The upper ends of the two groups of transmission components are respectively connected to different rotating components, and the two groups of transmission components are respectively located on both sides of the window hole 17. The upper end of the energy-absorbing component is connected to the lower ends of the two groups of transmission components, and the bottom of the energy-absorbing component is connected to the structural bottom beam 15, and the energy-absorbing component is located below the window hole 17. The self-resetting component is arranged inside the energy-absorbing component.

[0024] It should be noted that the self-resetting viscous damper described in this application is located between adjacent floors. In this application, the crossbeam located above the self-resetting viscous damper is referred to as the structural top beam 14, and the crossbeam located above the self-resetting viscous damper is referred to as the structural bottom beam 15. The transmission assembly is fixedly connected to the energy dissipation assembly, and the bottom of the energy dissipation assembly is fixedly connected to the structural bottom beam 15. When the structural top beam 14 undergoes a planar reverse displacement relative to the structural bottom beam 15, that is, Figure 1 In the left and right directions, the structural top beam 14 will drive the transmission component to move, and then drive the energy-absorbing component, and finally the structure set inside the energy-absorbing component will slow down the displacement of the structural top beam 14 relative to the structural bottom beam 15. When the structural top beam 14 and the structural bottom beam 15 stop moving relative to each other, the self-resetting component will push the structure set inside the energy-absorbing component back to the original position, playing a self-resetting role.

[0025] Each group of the rotating components includes an ear plate 9, a third rotating shaft 10, two upper support uprights 11 and an upper support embedded bottom plate 12; the upper support embedded bottom plate 12 is embedded in the structural top beam 14; a gap is provided between the two upper support uprights 11, and both are connected to the upper support embedded bottom plate 12 in parallel with the window opening 17; the ear plate 9 is located between the two upper support uprights 11; the third rotating shaft 10 passes through and is rotatably connected to the ear plate 9, and the two ends of the third rotating shaft 10 are rotatably connected to the two upper support uprights 11 respectively.

[0026] The rocker arm 8 and the ear plate 9 are an integrally formed structure, which increases the connection stability between the ear plate 9 and the rocker arm 8.

[0027] It should be noted that a gap is provided between the ear plate 9 and the two upper support plates 11, providing space for the ear plate 9 to move forward and backward, thereby preventing the application from being damaged when subjected to out-of-plane vibration, i.e., perpendicular to the swing direction of the rocker arm 8.

[0028] Each transmission assembly includes a vertical rocker arm 8, the upper end of which is connected to the lower end of the ear plate 9. In order to increase the bending stiffness of the rocker arm 8 and thus better match the energy-consuming unit with large resistance, in this embodiment, the cross section of the rocker arm 8 is H-shaped or rectangular.

[0029] The energy-consuming component includes a container shell 5 and two transmission arms 1, two transmission connecting plates 2, multiple cutting plates 3, viscous liquid 4 and multiple second rotating shafts 7 inside the container shell 5; the two transmission arms 1 are respectively located on both sides of the container shell 5, and the upper ends of the transmission arms 1 are fixedly connected to the lower end of the transmission component on the same side; the two transmission connecting plates 2 are horizontally arranged and have a spacing, and the two ends of the transmission connecting plates 2 are respectively rotatably connected to different transmission arms 1 through the second rotating shaft 7; the cutting plate 3 is vertically arranged, and the two ends are respectively rotatably connected to different transmission connecting plates 2 through the second rotating shaft 7, and the multiple cutting plates 3 are arranged in parallel with equal spacing; the transmission arms 1, the transmission connecting plates 2 and the cutting plates 3 together form a parallelogram hinge mechanism; the viscous liquid 4 fills the inside of the container shell 5.

[0030] The energy-consuming component further includes two first rotating shafts 6 , the middle of the first rotating shaft 6 passes through the transmission arm 1 , and both ends are connected to the container shell 5 , and the transmission arm 1 is rotatably connected to the container shell 5 via the first rotating shaft 6 .

[0031] In this embodiment, the first rotating shaft 6 is arranged at an upper position of the transmission arm 1. The transmission arm 1 drives the transmission connecting plate 2 and the cutting plate 3 to rotate under the transmission of the transmission assembly, and rotates and cuts the viscous liquid 4 in the container shell 5, converting the kinetic energy into the heat energy of the viscous liquid 4, thereby achieving the purpose of energy consumption.

[0032] The self-resetting assembly includes two reset springs 16 , which are located at both sides of the bottom of the container shell 5 , and one end of each reset spring 16 is connected to the transmission arm 1 on the same side, and the other end is connected to the inner wall of the container shell 5 .

[0033] It can be understood that when the structural top beam 14 and the structural bottom beam 15 stop relative movement, the return spring 16 located between the container shell 5 and the transmission arm 1 will push the transmission arm 1 and the rocker arm 8 connected thereto back to the vertical position, thereby achieving a self-reset effect.

[0034] The structural bottom beam 15 is pre-buried with a lower support pre-buried bottom plate 13 , and the bottom of the energy dissipation component is connected to the lower support pre-buried bottom plate 13 by welding or bolts, so as to increase the connection stability between the container shell 5 and the structural bottom beam 15 .

[0035] The present application has a simple structure, convenient installation, and a relatively small size. It effectively utilizes the free space around the window opening 17 and does not affect the arrangement of the building window opening 17. The energy dissipation principle is as follows: when encountering an earthquake or other vibration, the structural top beam 14 and the structural bottom beam 15 are relatively displaced, and the structural top beam 14 drives the rocker arm 8 through the rotating assembly, so that the rocker arm 8 drives the transmission arm 1 to rotate around the first rotating shaft 6, and the transmission arm 1 drives the transmission connecting plate 2 to rotate, and then drives the cutting plate 3 to rotate in the container shell 5, so that the parallelogram hinge mechanism formed by the transmission arm 1, the transmission connecting plate 2, and the cutting plate 3 rotates together to cut the viscous liquid 4 and convert it into heat energy of the viscous liquid 4, thereby achieving the purpose of damping energy dissipation. When the vibration stops, the reset spring 16 pushes the transmission arm 1 and the rocker arm 8 to reset.

[0036] For those skilled in the art, for different damping requirements, the speed at which the transmission arm 1, the transmission connecting plate 2, and the cutting plate 3 rotate together to cut the viscous liquid 4 can be adjusted by adjusting the length ratio of the rocker arm 8 and the transmission arm 1, thereby controlling the energy dissipation capacity of the viscous damper to achieve a better viscous energy dissipation effect. The energy dissipation capacity of the viscous damper can also be adjusted by adjusting the thickness, surface area, and number of the transmission arm 1, the transmission connecting plate 2, and the cutting plate 3, as well as the viscosity of the viscous liquid 4, so that the viscous damper can meet different energy dissipation requirements.

[0037] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
