[0035] Please refer to Figures 1 to 4, this embodiment provides an arrow cell stacking structure, including: a first panel 1; a second panel 2, arranged parallel to the first panel 1; a sandwich component, located between the first panel 1 and the second panel 2, and both sides of the sandwich component are respectively connected to the first panel 1 and the second panel 2; the sandwich component includes multiple core layers 3 stacked and connected in sequence; each core layer 3 includes a first corrugated plate 301 and a second corrugated plate 302; the corrugation structures of the first corrugated plate 301 and the second corrugated plate 302 are both triangular corrugations, and the included angle of the wave crests of the first corrugated plate 301 is smaller than the included angle of the wave crests of the second corrugated plate 302; the wave crest of each second corrugated plate 302 is correspondingly wrapped inside the wave crest of each first corrugated plate 301, and the wave trough of each first corrugated plate 301 is stacked and connected with the wave trough of each second corrugated plate 302 in a one-to-one correspondence; wherein, in two adjacent core layers 3, the wave crest of the first corrugated plate 301 of one core layer 3 is stacked and connected with the wave crest of the second corrugated plate 302 of the other core layer 3.
[0036] It should be noted that in the same core layer 3, the wave crests and wave troughs of the first corrugated plate 301 and the second corrugated plate 302 are stacked in a one-to-one correspondence; the wave crests of the first corrugated plate 301 and the second corrugated plate 302 face the same direction.
[0037] In this embodiment, multiple core layers 3 are sequentially stacked between the first panel 1 and the second panel 2 arranged in parallel. Each core layer 3 is formed by stacking and connecting a first corrugated plate 301 and a second corrugated plate 302. The topological structure formed by the sequential and alternating stacking of the first corrugated plate 301 and the second corrugated plate 302 has an obvious negative Poisson's ratio effect, enabling the sandwich component to play a supporting role between the first panel 1 and the second panel 2. When subjected to impact and collision, it can gather and contract towards the compressed area to form higher compressive and shear strengths. At the same time, it can absorb energy through deformation when being impacted, playing a good protective role, avoiding damage and destruction to important structures caused by accidental large-energy impacts, having a good anti-collision and energy-absorbing effect. Moreover, the sandwich component is formed by the sequential and alternating stacking connection of multiple first corrugated plates 301 and second corrugated plates 302, which can be modularly spliced, reducing costs and preparation difficulties, as well as later maintenance difficulties and maintenance costs. At the same time, according to actual needs, the angles between the crests and troughs of the first corrugated plate 301 and the second corrugated plate, and the stacking layers of the core layer 3 can be adaptively changed, thereby changing the anti-collision and energy-absorbing effect of the sandwich component; in addition, according to the structural scenario of the application, the bending curvatures of the first corrugated plate 301 and the second corrugated plate can be adaptively adjusted, and at the same time, the first panel 1 and the second panel 2 can be adaptively adjusted, which can be applied to plane structures or curved surface structures to play a protective role, and its application range is wide; in specific applications, the arrow cell stacking structure can be applied to the outer surface of building structures, such as cylindrical structures like bridge piers, or in large equipment (such as airplanes, high-speed rails, etc.) to play a protective role and avoid damage to building structures or large equipment when they are subjected to accidental large-energy impacts. This solves the technical problem that most existing building structures or large equipment are not easy to buffer the energy generated by accidental large-energy impacts, have poor anti-collision and energy-absorbing effects, and are easily damaged to building structures or large equipment.

When it is necessary to adjust the curvature of the core layer 3 to facilitate its application on the curved surface mechanism, the curvature of the core layer 3 can be changed by changing the angle between two adjacent double-arrow cells 4, that is, by changing the angle between the two adjacent first V-shaped plates in the first corrugated plate 301, and at the same time, the angle between the two adjacent second V-shaped plates in the second corrugated plate 302 is adaptively adjusted, then the angle between the two adjacent double-arrow cells 4 can be adjusted, and at the same time, the curvature of the first panel 1 and the second panel 2 is adaptively adjusted to facilitate the overall fitting of the curved surface structure of the engineering, which is isotropic in all directions perpendicular to the center of the circle, has better mechanical properties, and the adjustment and processing methods are simple and convenient, with better applicability and a wide range of applications.

[0063] The specific implementation manner of the arrow cell stack structure provided in this embodiment is as follows:
[0064] (1), Measure the usage area and radius size of the arrow cell stack structure to fabricate the sandwich component, the first panel 1 and the second panel 2 with corresponding radii;
