Buffering energy absorption seat

Abstract

The invention relates to the technical field of armored vehicle explosion protection devices, in particular to a buffering energy absorption seat. The seat device comprises a rubber gasket type energyabsorption and damping first-stage energy absorption mechanism, a spring damping element type second-stage energy absorption mechanism and a tubular foam aluminum type third-stage energy absorption mechanism, wherein the first-stage energy absorption mechanism, the second-stage energy absorption mechanism and the third-stage energy absorption mechanism are connected with a vehicle body, the second-stage energy absorption mechanism is not damaged after absorbing energy, and can be restored to the initial position after the impact, therefore the energy absorption mechanism capable of being repeatedly used is achieved, the first-stage energy absorption mechanism and the third-stage energy absorption mechanism can be rapidly replaced after impact deformation, and the economical efficiency ofthe seat is improved. According to the seat, energy absorption can be achieved in explosion impact, and the harm to passengers is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of explosion protection devices for armored vehicles, in particular to a cushioning energy-absorbing seat. Background technique [0002] As the level of protection and survivability of vehicles has increased, the level of casualties has dropped significantly. But some types of injuries have increased, and fatalities from secondary effects remain high, even in vehicles fitted with early blast-resistant seats. In order to protect the safety of the personnel in the armored vehicle in a mine explosion environment, when the vehicle is blown up, it is necessary to attenuate the energy generated by the explosion shock so that the energy finally transmitted to the occupant's body does not exceed the tolerance limit of the human body. At present, on the basis of welding or mechanical connection between the seat and the vehicle body, simply optimizing the seat to achieve lightning protection and energy absorption is ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the seat of the armored vehicle has poor occupant safety protection effect in the prior art, so as to provide a cushioning and energy-absorbing seat structure, which can effectively resist the shock waves and super high The damage caused by acceleration to various parts of the human body protects the lives of people in armored vehicles
