[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1As shown, the present invention comprises a sliding guide rod 1, a connecting plate 2 and a frame structure. The connecting plate 2 adopts a return-shaped structure, which is formed by two U-shaped plates connected by mortise and tenon joints, and is limited to separate from the left and right directions by bolt connection. The sliding guide rod 1 is sleeved on one end of the connecting plate 2, and a corrugated tension and compression plate 10 is installed between the sliding guide rod 1 and the connecting plate 2. The two ends of the corrugated tension and compression plate 10 are respectively connected to the sliding guide rod 1 and the connecting plate 2 by bolts. The other end of the connecting plate 2 is sleeved on the frame structure, and an energy dissipation part 13 is arranged inside the frame structure. The frame structure comprises a push plate 3 and a supporting plate 4. The supporting plate 4 adopts a U-shaped structure, and the push plate 3 adopts a right-angle structure. The right-angle push plate is located at the left end of the U-shaped supporting plate. The push plate 3 is located inside the connecting plate 2, and the supporting plate 4 is located outside the connecting plate 2. A first slot plate 51 is installed on the top of the push plate 3 by bolts, and a second slot plate 52 is installed on the inner wall of the top of the supporting plate 4 by bolts. The first slot plate 51 and the second slot plate 52 are engaged. Two limit rods 9 are welded on the left side of the push plate 3 to limit the lateral movement of the right-angle push plate.

[0022] like Figure 2 As shown, the energy absorbing part 13 includes a porous foam metal energy absorbing block 7, one end of the porous foam metal energy absorbing block 7 is connected to a first annular energy absorbing plate 61, and the other end is connected to a second annular energy absorbing plate 62 through a channel steel 8, and the first annular energy absorbing plate 61 and the second annular energy absorbing plate 62 are respectively connected to the porous foam metal energy absorbing block 7 by bolts, wherein the second annular energy absorbing plate 62 contacts the inner wall of the connecting plate 2, exerts a compressive effect on the second annular energy absorbing plate 62, and the first annular energy absorbing plate 61 contacts the inner wall of the push plate 3, exerts a compressive effect on the first annular energy absorbing plate 61. The porous foam metal energy absorbing block 7 is made of a foam metal material made by a foaming process, and the internal material of the energy absorbing block can be selected from porous foam aluminum, foam steel and other materials, and the energy absorbing capacity of the energy absorbing block can be effectively improved by utilizing its good energy absorbing and shock absorbing performance. A channel steel 8 is installed on one side of the porous foam metal energy dissipation block 7. The channel steel 8 is connected to the top steel plate by bolts, and a waist hole is opened on the top steel plate. When the channel steel 8 is under pressure, it can move along the waist hole direction and limit the out-of-plane displacement of the channel steel 8.

[0023] The ends of the sliding guide rod 1 and the supporting plate 4 are respectively provided with rectangular connecting blocks, and the entire damper is connected to the structure through the connecting blocks at both ends. When in use, the outer side of the damper is covered with a shell 12, such as Figure 3 As shown, the housing 12 is connected by bolts to limit the out-of-plane displacement of the composite metal damper.

[0024] Working principle:

[0025] When the sliding guide rod 1 of the composite metal damper is subjected to pressure, the sliding guide rod 1 will squeeze the right-angle push plate, and the corrugated tension and compression plate 10 will be stretched to dissipate some energy; then, the right-angle push plate will squeeze the overall energy dissipation part, and the first annular energy dissipation plate and the second annular energy dissipation plate in the overall energy dissipation part will first undergo plastic deformation to dissipate energy and reduce shock, and then the porous foam metal energy dissipation block will use the high damping characteristics of its foam metal to dissipate energy. In addition, due to the low recovery of the foam metal, after the load is applied, the first card slot plate on the upper part of the right-angle push plate will be snap-fastened with the second card slot plate on the upper part of the U-shaped support plate, so that the sliding guide rod can directly contact the right-angle push plate when the next load is applied. Similarly, when the sliding guide rod of the metal damper is subjected to tension, the sliding guide rod will pull the return-shaped connecting plate to move together, and the return-shaped connecting plate will squeeze the overall energy dissipation part, making full use of its high damping and specific stiffness characteristics to dissipate energy and reduce shock. The energy is fully dissipated by combining the porous foam metal energy dissipation block and the annular energy dissipation plate, thereby realizing a staged and multi-mode energy dissipation damper.

[0026] The metal damper of the present invention is provided with an annular energy-absorbing plate and a corrugated tension-compression plate, and energy is absorbed by the plastic deformation of the annular energy-absorbing plate and the corrugated tension-compression plate; secondly, a porous foam metal energy-absorbing block is provided, and energy is absorbed by the pressure of the porous foam metal energy-absorbing block, and the internal material of the energy-absorbing block can be selected from porous foam aluminum, foam steel and other materials, and the energy-absorbing capacity of the energy-absorbing block can be effectively improved by utilizing its good energy-absorbing and shock-absorbing performance. The energy-absorbing through the above-mentioned various forms of combined energy-absorbing can make up for the shortcomings of the single energy-absorbing method of ordinary energy-absorbing by metal plates. Furthermore, the damper adopts porous foam metal materials to realize the diversity and effectiveness of energy-absorbing methods. The damper has a simple structure and easy-to-process parts. It is connected by bolts and mortise and tenon joints, which is convenient for on-site installation and easy to use.
