Embodiment Construction

[0036] The purpose of the present invention is to reduce the leg injury of the occupant in an explosive environment, thereby providing a lightning protection lower limb protection device for military vehicles, which can reduce the calf force and effectively reduce the occupant injury by buffering the impact from the floor and dispersing the explosion energy.

[0037] The protection device includes a foot pad and a flexible energy-absorbing floor, and the foot pad is fixed to the upper part of the flexible energy-absorbing floor with rivets;

[0038] Such as Figure 4 As shown, the foot pad 6 includes two parts, the semicircular tube 3 and the upper plate 1 . Wherein the semicircular pipe 3 is connected with the upper plate 1 through rivets, and a tight connection is established to enhance the connection strength of the foot pad. The upper plate 1 provides support and dispersion.

[0039] The lightning protection foot pad for military vehicles absorbs the impact transmitted f...

Abstract

The invention relates to the technical field of anti-explosive armored vehicles, in particular to a military vehicle anti-mine lower limb protection device. The protection device includes a foot pad and a flexible energy absorbing floor, and the foot pad is fixed to the upper part of the flexible energy absorbing floor through a rivet; and the foot pad includes an upper flat plate and a pluralityof semicircular tubes on the lower part of the upper flat plate, the multiple semicircular tubes are fixed to a lower flat plate, the multiple semicircular tubes are arranged in a plurality of rows, the number of the semicircular tubes in each row is not less than three, the semicircular tubes between the adjacent rows are arranged in a staggered mode, and the upper flat plate is placed under human feet. The semicircular tubes are placed above the floor. According to the lower limb protection device, the anti-mine foot pad is arranged, the semicircular tubes compress to absorb energy and improve rigidity to enhance the leg protection performance, the flexible anti-mine floor is arranged, when the explosion impact is transmitted to the floor, the energy absorption effect is achieved by deformation of a bracket and the upper plate, the energy is dispersed, and the leg injury of a human body is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of explosion-proof armored vehicles, in particular to a lightning-proof lower limb protection device for military vehicles. Background technique [0002] At the moment of the mine explosion, the impact force is immediately applied to the feet through the body, and then quickly transmitted to the calves and thighs. Currently, 90% of vehicles fail blast resistance tests due to foot problems. As far as the design of light vehicles is concerned, the first-level protective structure cannot resist explosions, so a second-level protective structure needs to be adopted to isolate the impact and reduce lower limb injuries; and pedals cannot be designed to isolate the impact, and a series of measures need to be taken to reduce leg injuries; In addition, because the vehicle is light and close to the blast point, a dedicated isolation system must be installed. [0003] Faced with the above situation, different protect...
