Vehicle body floor system suitable for air drop

Abstract

The invention discloses a vehicle body floor system suitable for air drop, and the system comprises a doorsill beam, a floor, floor cross beams, floor longitudinal beams, an energy absorption component, a middle bulge, a power protection steel component and a mounting component; the two floor longitudinal beams form a left mounting area, a power mounting area and a right mounting area; a plurality of floor cross beams are arranged in the left mounting area, the power mounting area and the right mounting area; an opening of the floor longitudinal beam faces one side of the floor cross beam, and an opening of the floor cross beam faces upwards; the energy absorption components are square aluminum pieces and are arranged on the two floor cross beams; the energy absorption component and the platform longitudinal beam are oppositely arranged; the power protection steel member is packaged below the mounting member; the power protection steel member and the air bag are oppositely arranged; and the middle bulge, the floor longitudinal beam, the mounting component and the power protection steel component form a power mounting space for mounting a power assembly. The Z-direction impact-resistant vehicle body is high in structural strength and rigidity and has excellent Z-direction impact resistance, and repeated use of the vehicle body during air drop is achieved.

Description

technical field [0001] The invention belongs to the technical field of air-dropped vehicle body floors, and more particularly, relates to a vehicle-body floor system suitable for air-dropping. Background technique [0002] As an essential means of transportation for modern people, the safety and anti-collision performance of the vehicle are the primary considerations. The main anti-collision design of the existing vehicle floor focuses on the collision of the front and rear of the vehicle (that is, the X direction), but for the collision from the ground. The vertical (ie Z direction) collision avoidance is not involved. For example, the prior art CNCN109606476A discloses a body floor structure. In the body floor structure described in the patent, the front cowl reinforcement plate and the cowl longitudinal beam form a mountain-shaped structure, thereby forming three force transmission channels, so that the collision from the front The force is transmitted along the three fo...

AI Technical Summary

Problems solved by technology

[0003] In the existing airdrop, the vehicle needs to be dropped from the air to the ground through the non-cargo platform airdrop system. Since the existing vehicle has no anti-collision design in the Z direction, the vehicle is easy to be damaged or even malfunctions during the delivery process, and it cannot be effectively carried out on land. driving, so those skilled in the art urgently need to develop a body floor system suitable for airdrops
