[0021] (4) This device adopts a multi-stage shock absorption method. When there is no external force or the external force is small, the main energy consumption device is separated from the central axis and the main energy consumption device does not work. When the force reaches a certain value, the main energy consumption device is connected to the central axis and the main energy consumption device works.

[0022] (5) By utilizing the reset performance of the memory alloy rod, it can have a strong self-reset performance after the earthquake, thereby improving the utilization rate of the device.

[0023] (6) The damper response amplification technology is used. This technology uses various mechanisms or mechanical devices to amplify the displacement and velocity of the structure, so that the damper can also play a significant energy dissipation capacity under small earthquakes or wind loads. At the same time, under large earthquakes, since the effect of the damper is amplified, its energy dissipation effect will also increase, which helps to reduce the number of dampers, reduce the cost of energy dissipation and shock absorption structures, and achieve better economic benefits. In addition, this device still has a good energy dissipation and shock absorption effect under small and medium earthquakes, and is not easy to fail under large earthquakes.

DETAILED DESCRIPTION

[0033] Here, exemplary embodiments will be described in detail, and the embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are only examples of devices consistent with some aspects of the present invention as detailed in the appended claims. Example

[0034] like Figure 1-6 As shown, a new type of self-resetting energy-absorbing support device includes a shell 2, and transmission parts are provided on both side walls of the shell 2. A transmission device and an energy-absorbing device are provided in the shell 2. Energy is transmitted to the energy-absorbing device through the transmission device, and energy consumption is realized through the energy-absorbing device.

[0035] This device uses a combination of a viscous damper and a displacement amplification damper, allowing the viscous damper to move back and forth within a limited stroke, preventing it from failing under rare earthquakes, thereby ensuring that the structure achieves good energy dissipation and shock absorption effects under all levels of earthquakes.

[0036] A multi-stage shock absorption method is adopted. When there is no external force or the external force is small, the main energy consumption device is separated from the central axis and the main energy consumption device does not work. When the force reaches a certain value, the main energy consumption device is connected to the central axis and the main energy consumption device works.

[0037] Furthermore, the transmission member includes a first transmission member and a second transmission member, the first transmission member includes a first transmission rod 8, the first transmission rod 8 is connected to the first side wall of the housing 2, the outside of the first side wall is connected to the first connecting member 1-1, and the first transmission rod 8 is provided with teeth;

[0038] The second transmission member includes a second transmission rod 9, a connecting plate 4 is provided in the outer shell, the second transmission rod 9 is connected to the connecting plate 4, the connecting plate 4 is connected to the second side wall of the outer shell 2 through multiple first memory alloy rods 7, and a second connecting member 1-2 is provided on the outside of the second side wall, and the second side wall is arranged opposite to the first side wall.

[0039] In this embodiment, the reset performance of the memory alloy rod can have a strong self-reset performance after an earthquake, thereby improving the utilization rate of the device.

[0040] Furthermore, the transmission device includes a central shaft system and a side shaft system, and the side shaft system is driven to rotate by the central shaft system.

[0041] A new type of self-resetting energy-absorbing support, the device is symmetrical in both vertical and horizontal directions. The central shaft 5 and the side shaft 6 are divided into two layers, the inner layer is the axis, connected to the outer shell 2, and cannot rotate; the outer layer is the outer sleeve, on which the gear and disc are fixed, and can rotate around the inner axis.

[0042] The first side wall of the housing 2 is connected to the first connecting member 1-1, and the second side wall of the housing 2 is connected to the first transmission rod 8. The left side of the connecting plate 4 is connected to the second transmission rod 9, and the right side is connected to four first memory alloy rods 7 and the second connecting member 1-2. The other end of the first memory alloy rod 7 is connected to the housing 2. The inner sides of the other ends of the first transmission rod 8 and the second transmission rod 9 are toothed and mesh with the third center shaft gear 5-4. The viscous damper 16 is internally equipped with a piston plate 16-4, and the space enclosed by the piston plate 16-4 and its bottom is filled with a viscous liquid. One end of the piston rod is connected to the piston plate 16-4, and the other end is connected to the first disc 6-1 via the first connecting rod 12. The end of the first connecting rod 12 connected to the first disc 6-1 is connected to the housing 2 via the second memory alloy rod 13. The expansion device 11 is located between the two large gears of the central axis. The second ring 11-2 and the first ring 11-4 are sleeved on the central axis 5. One end of the first steel cable 11-1 is connected to the first outer sleeve 5-1, and the other end is connected to the first seesaw 11-3 and the second seesaw 11-6.

[0043] The principle is as follows: when the device is subjected to a small force, the first connecting member 1-1 and the second connecting member 1-2 move relative to each other, driving the first transmission rod 8 and the second transmission rod 9 to move relative to each other. The first central axis gear 5-5, the second central axis gear 5-7, and the third central axis gear 5-4 are sleeved on the first outer sleeve 5-1, causing the second central axis gear 5-7 to rotate, and the first outer sleeve 5-1 also rotates. The first steel cable 11-1 connected to the first outer sleeve 5-1 is wound around the first outer sleeve 5-1 as it rotates. The first steel cable 11-1 is wound around the first outer sleeve 5-1. The other end of the central axis 1 is pulled, and through the expansion device 11, the first ring 11-4 and the second ring 11-2 push the first central axis gear 5-5 along the central axis 5 toward the end. The first spring 5-3 and the second spring 5-8 are compressed, but the force is small. The first central axis gear 5-5 and the second central axis gear 5-7 do not move outward far enough and do not engage with the first side axis gear 6-2. At this time, the main energy dissipation system is inoperative, and energy is consumed only through friction between the first transmission rod 8, the second transmission rod 9, and the second central axis gear 5-7. The relative movement of the first transmission rod 8 and the second transmission rod 9 compresses or stretches the four first memory alloy rods 7, causing the memory alloy rods to deform and further consume some energy. When the force is removed, the first memory alloy rod 7 returns to its original state, and the first spring 5-3 and the second spring 5-8 reset themselves, causing the system to reset.

[0044] When the device is subjected to a large force, the first connecting member 1-1 and the second connecting member 1-2 move relative to each other, driving the first transmission rod 8 and the second transmission rod 9 to move relative to each other, causing the second central axis gear 5-7 to rotate, and the first outer sleeve 5-1 also rotates. The first steel cable 11-1 and the second steel cable 11-5 connected to the first outer sleeve 5-1 are wrapped around the first outer sleeve 5-1 as they rotate. The other end of the first steel cable 11-1 is pulled, and through the expansion device 11, the first ring 11-4 and the second ring 11-2 push the first central axis gear 5-5 and the second central axis gear 5-7 to move outward, and the first spring 5-3 is compressed. Due to sufficient force, the first central axis gear 5-5 moves a sufficient distance along the central axis 5 to the end, meshing with the first side axis gear 6-2 and the second side axis gear 6-5, and the main energy consumption system works. At this time, the first central shaft gear 5-5 will cause the first side shaft gear 6-2 meshing with it to rotate, and the rotation of the third central shaft gear 5-4 will drive the second side shaft gear 6-5 to rotate, and the first disc 6-1 and the second disc 6-7 coaxial with the first side shaft gear 6-2 and the second side shaft gear 6-5 will also rotate, and the two discs on the left and right sides have the same rotation direction. Finally, the first connecting rods 12 on the left and right sides push the piston rod, driving the piston plate 16-4 to reciprocate back and forth in the viscous damper 16, continuously squeezing the viscous liquid to move back and forth in the two chambers of the viscous damper 16, increasing energy consumption. At the same time, in the gear transmission, when the first center shaft gear 5-5 rotates a certain angle, due to the tooth ratio between the first center shaft gear 5-5 and the first side shaft gear 6-2, and between the third center shaft gear 5-4 and the second side shaft gear 6-5, the first side shaft gear 6-2 and the second side shaft gear 6-5 will rotate a larger angle, increasing the number of times the piston plate 16-4 reciprocates in the viscous damper 16, achieving greater energy consumption. When the force is removed, the first spring 5-3 and the second spring 5-8 reset themselves, pushing the first center shaft gear 5-5 and the third center shaft gear 5-4 back to their original positions. The first center shaft gear 5-5 and the first side shaft gear 6-2, and the third center shaft gear 5-7 and the second side shaft gear 6-5, no longer mesh, and the two parts reset themselves. The second memory alloy rod 13 returns to its original state, causing the main energy consumption system to reset. The first memory alloy rod 7 returns to its original state, causing the central system to reset.
