A mine-proof seat for a vehicle

Abstract

A vehicle anti-mine seat, comprising a seat body, the seat body is composed of a seat frame, a seat seat surface and an energy absorber; the side where the seat seat surface is connected to the seat frame is provided with a horizontal lower mounting rod, The two ends of the lower mounting rod are connected with the sliding sleeve sleeved on the main rod of the seat frame. The sliding sleeve is provided with a linear bearing, and the linear bearing, the sliding sleeve, and the lower mounting rod lead the seat surface along the main rod. Slide up and down; the middle part of the lower mounting rod is connected with a longitudinal transfer rod, the upper end of the transfer rod is hung on the energy absorber, and the upper end of the energy absorber is installed in the middle of the upper mounting rod; the upper mounting rod is fixedly connected to the main on the pole. The seat also includes a suspension installation mechanism, the suspension installation mechanism is composed of an upper installation part fixed on the side wall of the vehicle body or a top installation part fixed on the top of the vehicle body, and a lower installation part fixed on the bottom plate of the vehicle body. The invention reduces the detonation impact energy transferred to the seat through the suspension installation mechanism, and further reduces the energy transfer to the human body through the energy absorber, so as to protect the safety of personnel.

Description

technical field [0001] The invention relates to the field of seats, in particular to a vehicle anti-mine seat. Background technique [0002] The level of armor protection technology of modern armed vehicles is getting higher and higher, but the data obtained from foreign battlefields and peacekeeping missions show that the casualties caused by anti-vehicle mines or improvised explosives are still on the rise, because tanks and armored vehicles In the case of such attacks, many casualties are not caused by the breakdown of the armor, but by the detonation impact energy transmitted to the human body through vehicles, seats and other structures. If the seat structure is poorly designed, it will eventually be transmitted to the occupants The shock wave energy of the explosion can be as high as 20 to 30 times the human body's tolerance limit, and the threat of casualties to the occupants is usually more serious than the explosion itself, which can easily cause major casualties su...

AI Technical Summary

Problems solved by technology

There are a few applications of lightning protection seats in foreign countries, but the installation and energy absorption methods are not coordinated, the energy absorption effect is not maximized, and it cannot meet the installation requirements of domestic vehicles
