Semi-active suspended type lightning protection shock absorbing seat

Abstract

The invention relates to a semi-active suspended type lightning protection shock absorbing seat. The semi-active suspended type lightning protection shock absorbing seat comprises a seat and a chair back; the seat is fixedly connected with the chair back through an arc fixing frame; lifting rods are vertically arranged on the two sides of the seat; the top of each lifting rod is detachably connected with the top of a vehicle body; bottom stopping sheets are detachably connected to the bottoms of the lifting rods and arranged perpendicular to the lifting rods; magnetic fluid rheostat adjustingmechanisms are arranged under the lifting rods; the upper ends of the magnetic fluid rheostat adjusting mechanisms are fixedly connected with the bottoms of the corresponding sides of the seat; sensors are arranged between the tops of the lifting rods and the top of the vehicle body; the sensors are electrically connected with a controller; the controller is electrically connected with a power supply generator; and the power supply generator is electrically connected with the magnetic fluid rheostat adjusting mechanisms. The semi-active suspended type lightning protection shock absorbing seathas the advantageous effects that the assembling and disassembling are convenient; the floor space is small; by using magneto-rheological characteristics of magnetorheological fluids, variable rigidity and variable damping can be realized to be convenient for effectively absorbing impact loads; active adaptation to different vibrational excitation is strong; and a very good protection effect on the safety of vehicle-mounted personnel is realized.

Description

technical field [0001] The invention relates to the technical field of safety protection for vehicle-mounted personnel of military vehicles, in particular to a semi-active lightning-proof and shock-absorbing seat applied to military vehicles. Background technique [0002] Anti-tank landmines are a serious threat to the vehicle crew of military vehicles. The shock waves and impact force generated by landmines are transmitted to the vehicle personnel through the body or seats, causing injury or even death. At present, the main research on the vibration reduction of military vehicles is the optimal design of the vehicle body, but due to the limited space in the vehicle, most of the seats installed on military vehicles do not have special lightning protection and vibration reduction devices. [0003] Chinese patent CN101712288A discloses a lightning-proof and shock-absorbing seat applied to an armored vehicle, which includes a seat back and a seat cushion, and the seat back and ...
