Manual adjustment buffer isolation device of military vehicle lightning protection seat and using method

Abstract

The invention belongs to the technical field of explosion-proof armored vehicles, and particularly relates to a manual adjustment buffer isolation device of a military vehicle lightning protection seat. The device comprises a fixing mechanism, a starting mechanism, an energy absorption mechanism and a manual adjusting mechanism, wherein the fixing mechanism is used for connecting the buffer isolation device with a seat framework; the starting mechanism is used for preventing false triggering of the energy absorption mechanism and starting of a buffer energy absorption process of the buffer isolation device; the energy absorption mechanism is used for achieving buffering and absorption of impact energy in an explosion process and includes a steel belt, two steel belt limiting pins and a push block, and the steel belt sequentially penetrates through the steel belt limiting pin, the push block and the other steel belt limiting pin and is wound and attached in a triangular shape; and the manual adjusting mechanism is used for adjusting an energy absorption load of the buffer isolation device according to different weights of passengers. According to the device, energy is buffered and absorbed through plastic deformation generated by the steel belt when the seat is impacted, and impact energy can be greatly attenuated; and the energy absorption load of the buffer isolation device ischanged through an adjusting knob, and an energy absorption effect of the lightning protection seat can be changed according to the weights of the passengers.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof armored vehicles, and in particular relates to a manually adjustable buffering isolation device and a use method for a lightning protection seat of a military vehicle. Background technique [0002] In the current anti-terrorist war and future armed conflicts, the anti-lightning seat of military vehicles has become the most important part of protecting the safety of occupants in the vehicle. Although the current design of the lightning protection seat cushioning and isolation device in the vehicle can buffer the impact strength and absorb the impact energy under the condition that the vehicle is subjected to the impact of the bottom explosion, the same buffer and isolation device cannot provide protection due to the difference in the weight of the combat crew. corresponding protection. [0003] Faced with the above situation, in recent years, foreign countries have begun to develop lightni...

Problems solved by technology

[0004] Objectively speaking, although many manufacturers have put in a lot of effort in the research on the body weight adaptation technology of the lightning protection seat buffer isolation device, and have some experience in the theoretical research of the body weight adaptation technology, it is still difficult to realize the adjustment of human body weight. certain complexity
