[0025] When using the lightweight bottom protection structure of the special vehicle, Figure 1 and Figure 2As shown, the upper end of the impact-resistant steel plate 1 is fixedly connected with a first foam aluminum plate 2, and the first foam aluminum plate 2 is fitted between the impact-resistant steel plate 1 and the foam aluminum back plate 3, and the thickness of the impact-resistant steel plate 1 is 4-10mm, and the thickness of the first foam aluminum plate 2 is 5-25mm, and the width is 100 to 200mm. At the same time, a second foam aluminum plate 5 is fitted between the foam aluminum back plate 3 and the bottom mounting back plate 4 of the special vehicle, and through holes 7 are evenly spaced in the first foam aluminum plate 2, and the edges of the impact-resistant steel plate 1 and the foam aluminum back plate 3 are not connected, but are in an open state, which can better play a buffering effect. Because the first foam aluminum plate 2 and the foam aluminum back plate 3 are closed-cell structures, the waterproof requirements of the components can be met. Combined with the through holes 7, the first foam aluminum plate 2 is in a hollow state, so that the impact surface is fully deformed when a collision occurs, and the first foam aluminum plate 2 is fully compressed. The actual buffering effect is good, which is beneficial to protecting the chassis of the special vehicle, and the number and size of the through holes 7 can be adjusted to optimize the protection requirements.
