Front explosion-proof seat of military vehicle

Abstract

The invention belongs to the field of explosion-proof armored vehicles, and particularly relates to a front explosion-proof seat of a military vehicle. The seat comprises a fixed part, a movable partand energy-absorption elements, wherein the fixed part comprises heaven-ground beams and guide rails which are fixed to the ridge and grade beams, and the fixed part is used for supporting a seat frame and making the seat frame fixed to the vehicle; the movable part comprises the seat frame and sliders, the movable part is used for installing a seat cushion, and the movable part is slidably arranged on the fixed part through the sliders and the guide rails; the energy-absorption elements are arranged between the fixed part and the movable part, and used for absorbing energy generated in the explosion impact process. According to the explosion-proof seat, by installing the energy-absorption elements, energy absorption and buffering are achieved, and the explosion impact is reduced; the heaven-ground installation way is adopted, compared with hanging installation, the support stiffness of the overall frame is increased, the space requirements are low, and therefore, the passenger safetyspace is expanded. The protection performance of the seat is effectively improved, the injury to a passenger is greatly reduced, the cost is reduced, and the reusability of the seat is improved.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof armored vehicles, in particular to a front explosion-proof seat of a military vehicle. Background technique [0002] In the current anti-terrorist war and future armed conflicts, improving armored vehicles' ability to protect against explosives such as landmines, roadside bombs and improvised explosive devices, especially to ensure the safety of occupants has become an issue of increasing concern to research institutions at home and abroad. As far as interior design is concerned, seat design is the key to reducing casualties. Faced with this situation, different anti-explosion seats have been developed abroad, but they all have certain defects. [0003] For example, the suspension seat developed by Autoflug Company performs well in different explosion tests, but its space requirement is large, and it cannot defend against the secondary effect; the BlastRide series seat developed by Qineti...

AI Technical Summary

Problems solved by technology

[0003] For example, the suspension seat developed by Autoflug Company performs well in different explosion tests, but its space requirement is large, and it cannot defend against the secondary effect; the BlastRide series seat developed by QinetiQ North America Company has realized small space and light weight, due to its Integrated design, inconvenient for matching and replacement of special models

[0004] However, our country is facing the phenomenon of low technical ability and serious structural homogeneity.
