Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The embodiment provides a lightning protection armor for an armored vehicle, the structure of which is shown in fig. 1 to 3, and the lightning protection armor comprises: the armor panel 1, the foam metal layer 2, the armor back plate 5 and the connecting column 3; wherein the content of the first and second substances,

the armor panel 1 and the armor back plate 5 are arranged in parallel, the armor panel 1 is made of a tough material, and the hardness of the armor back plate 5 is greater than that of the armor panel 1; one end of the connecting column 3 is fixedly connected with the middle part of the armor panel 1, and the other end is fixedly connected with the middle part of the armor back plate 5, so that the armor panel 1 and the armor back plate 5 are fixedly connected together; the foam metal layer 2 is filled between the armor panel 1 and the armor back plate 5, and the connecting column 3 is coated inside the foam metal layer 2.

Specifically, the armor back plate 5 is made of an armor steel plate with the hardness of 400-550 HBW and the thickness of more than or equal to 6mm, has high strength and rigidity, can ensure small deformation when bearing explosion impact so as to ensure the space in the armored vehicle, and the armor back plate 5 is provided with a mounting hole for connecting the lightning protection armor for the armored vehicle with the body of the armored vehicle, as shown in fig. 1 and 3; the armor panel 1 is an armor steel plate with the hardness of 300-500 HBW and the thickness of more than or equal to 6 mm; the armor panel 1 directly bears explosion impact, has protection capability and simultaneously has good forming capability, the armor panel 1 deforms to absorb partial energy when bearing the explosion impact, and meanwhile, the deformed armor panel 1 forms a traditional V-shaped armor and has the capability of discharging energy to the periphery of a vehicle body, wherein one side can deform to form a single-side V-shaped structure when bearing the explosion, as shown in figure 4; and the middle or both sides will deform to form a multi-dimensional V-shaped structure when subjected to an explosion, as shown in fig. 5.
