Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0032] like figure 1 The leg protection device shown includes a hollow energy-absorbing upper panel, a right hollow support plate, a hollow energy-absorbing lower panel, a concave hexagonal negative Poisson's ratio sandwich layer, and a left hollow support plate.
[0033] like figure 1 and Figure 4 As shown, the hollow energy-absorbing upper panel 1 and the hollow energy-absorbing lower panel 3 are perpendicular to the direction of the concave hexagonal plane 8 of the concave hexagonal negative Poisson's ratio sandwich layer 4; the hollow energy-absorbing upper panel 1 And the length direction of the rectangular hollow 10 of the hollow energy-absorbing lower panel 3 is parallel to the direction of the concave hexagonal plane 8 of the concave hexagonal negative Poisson's ratio sandwich layer 4 . The hollow support plate 2 on the right side and the hollow s...
