Military vehicle lightning protection seat energy absorption device

Abstract

The invention relates to the technical field of explosion-proof armored vehicles, and particularly relates to a military vehicle lightning protection seat energy absorption device. The device comprises a fixing mechanism, a guide mechanism, a starting mechanism and an energy absorption mechanism. The fixing mechanism comprises an energy absorption device upper connecting block and a lower connecting block which are connected with corresponding mounting points of upper and lower cross beams of a seat framework through bolts; the guide mechanism comprises an elastic piece mounting block and an external box of the energy absorption device, and the elastic piece mounting block and the external box jointly restrain a motion trail of the energy absorption device in a working process of the energy absorption device; the starting mechanism comprises an elastic sheet and a constraint bolt and is connected with the elastic sheet mounting block; and the energy absorption mechanism comprises a steel belt and a steel belt limiting bolt, and the elastic piece mounting block is connected with a fixing and supporting mechanism after connecting the steel belt through the bolt. According to the lightning protection seat energy absorption device, buffering energy absorption is achieved through plastic deformation generated by the steel belt when the seat is impacted, an explosion impact is reduced, impact energy can be greatly relieved, and protection performance of the seat is effectively improved.

Description

technical field [0001] The invention relates to the technical field of explosion-proof armored vehicles, in particular to an energy-absorbing device for a lightning-proof seat of a military vehicle. Background technique [0002] In the current anti-terrorist war and future armed conflicts, although the energy-absorbing components at the bottom of military vehicles and the shock wave bias technology can effectively resist the impact of landmines and improvised explosive devices, the extreme acceleration brought by the shock wave to the vehicle body and the impact of the vehicle body The fall process can still cause great harm to the occupants of the car. Therefore, the design of lightning-proof seats in the vehicle is the key to reducing casualties. It can buffer the impact intensity and absorb the impact energy under the condition that the vehicle is subjected to the impact of the bottom explosion, and control the impact peak value and impact time of the occupants within a s...

Problems solved by technology

[0003] Faced with the above situation, foreign countries have developed lightning-proof seats equipped with different forms of energy-absorbing devices, such as the lightning-proof seat of GSS Company, the dynamic suspension seat of Autoflug Company, the lightning-proof seat of Jianke Company, and the anti-lightning seat of Creation Company. Lei seat, etc.; however, due to the late start of domestic research in this area, the relevant technology is not mature enough, and only a few seat companies are exploring and developing

[0004] Although many manufacturers have made a lot of efforts in the research of energy-absorbing devices for lightning protection seats, and the safety of occupants in the car has been improved to a certain extent, there is still a lot of room for improvement in energy-absorbing devices for lightning protection seats.
