The structural strength of the profile plates can be enhanced through the arrangement of the vertical profile plates, the reinforcing plates 6 and the transverse plates 12, and the transverse plates 12 divide the vertical profile plates into a space, so that a space is provided for the placement of the energy absorption pad. The T-shaped structural cross plate 12 can buckle the energy absorbing pad against falling off.

The working principle of the embodiment is as follows:
the guide rail 2 is fixedly connected to the outside of the ship body 1, then the sliding groove at the left end of the connecting strip 3 is scratched into the guide rail 2, and then two ends of the profile plate are scratched into the sliding groove at the lower end of the connecting strip 3, so that the addition of the profile plate is completed. The sectional material plate and the connecting strip 3 are connected in a sliding way, so that the sectional material plate can be flexibly and conveniently taken out or added.
The energy absorption pad is added into the space from the two ends of the profile plate to the nearest transverse rod 7, and the length of the energy absorption pad is longer than that of the transverse plate 12, so that the transverse plate 12 can be prevented from being directly contacted with a collision object, and the transverse plate is prevented from being crushed. The right end of the energy-absorbing pad is connected with a soft board 5 for protecting the energy-absorbing pad, so that the outer layer of the energy-absorbing pad is reduced from being scratched.

By the interconnection of the pushrods 7 and the interconnection of the vertices of the isosceles triangle base, it is achieved that all negative poisson's ratio structures 4 are connected as one whole.
When the push rod 7 of the negative poisson ratio structure 4 is stressed, the force is transmitted to the first elastic plate 8 or the first elastic plate 8 and the second elastic plate 9 connected with the push rod, and the first elastic plate 8 and the second elastic plate 9 deform to cause the whole negative poisson ratio structure 4 to deform, so that the negative poisson ratio structure 4 connected with the push rod is correspondingly deformed, and each negative poisson ratio structure 4 can bear a part of the stress. The total pressure is dispersed by all negative poisson's ratio structures 4 and when the pressure is lost, all negative poisson's ratio structures 4 return to their original shape under the force of their elasticity. The adoption of the negative poisson ratio structure 4 can make the whole energy absorption pad fluffy, so that the use of the negative poisson ratio structure 4 is reduced, the use of materials is saved, the deformation space of the energy absorption pad is increased, and the energy absorption pad can fully absorb the pressure from collision.
