Landmine-preventing seat of vehicle

Abstract

The invention discloses a landmine-preventing seat of a vehicle. The landmine-preventing seat of the vehicle comprises a seat body, wherein the seat body is composed of a seat frame, a seat surface and an energy absorber, a transverse lower hanging rod is arranged on the side where the seat surface is connected with the seat frame, the two ends of the lower hanging rod are connected with a sliding sleeve, the sliding sleeve is connected to a main rod of the seat frame in a sleeved mode, a linear bearing is arranged in the sliding sleeve, the linear bearing, the sliding sleeve and the lower hanging rod drive the seat surface to slide up and down along the main rod, a longitudinal turn-connecting rod is connected to the middle of the lower hanging rod, the upper end of the turn-connecting rod is hung on the energy absorber, the upper end of the energy absorber is installed in the middle of an upper hanging rod, and the upper hanging rod is fixedly connected to the main rod. The landmine-preventing seat further comprises a hanging installation mechanism, wherein the hanging installation mechanism is composed of an upper installation piece or a top installation piece and a lower installation piece, the upper installation piece is fixed to the side wall of the body of the vehicle, the top installation piece is fixed to the top of the body of the vehicle, and the lower installation piece is fixed to a bottom plate of the body of the vehicle. According to the landmine-preventing seat of the vehicle, detonation impact energy transmitted to the seat is reduced through the hanging installation mechanism, energy transmitted to a human body is further reduced through the energy absorber, and personnel safety is guaranteed.

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
