A Body Floor System Adapted to Airdrops

Abstract

The invention discloses a vehicle body floor system adaptable to airdrop, comprising: a threshold beam, a floor, a floor beam, a floor longitudinal beam, an energy-absorbing member, a center drum, a power protection steel member and an installation member; two floor longitudinal beams form a left installation area, power installation area, and right installation area; multiple floor beams are arranged in the left installation area, power installation area, and right installation area; the opening of the floor longitudinal beam is set toward the side of the floor beam, and the opening of the floor beam is set upward; the energy-absorbing member is The mouth-shaped aluminum parts are arranged on the two floor beams; the energy-absorbing member is arranged opposite to the cargo platform longitudinal beam; the power protection steel member is packaged under the installation member; the power protection steel member is arranged opposite to the air bag; the middle bulge, floor longitudinal beam, The mounting member and the power protection steel member form a power installation space for installing the powertrain. The invention has high structural strength and rigidity and excellent anti-impact performance in the Z direction, and realizes airdropping and repeated use of the vehicle body.

Description

technical field [0001] The invention belongs to the technical field of airdrop vehicle body floor, and more specifically relates to a body floor system suitable for airdrop. Background technique [0002] Vehicles are a necessary means of transportation for modern people, and their safety and anti-collision performance are people's primary considerations. The main anti-collision design of the existing vehicle floor focuses on the front and rear (ie X direction) collisions of the vehicle, but for the impact from the ground The vertical (ie Z direction) collision avoidance is not involved. For example, the prior art CNCN109606476A discloses a car body floor structure. In the body floor structure described in the patent, the front wall reinforcement plate and the front wall stringer 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 power transmission channels and avo...

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
