Floor beam structure applied to vehicle

Abstract

The invention provides a floor beam structure applied to a vehicle. The structure comprises a middle channel, underfloor longitudinal beams, floor cross beams and inclined connecting beams, wherein the underfloor longitudinal beams are located on the left side and the right side of the middle channel; the floor cross beams are disposed on the left side and the right side of the middle channel, thefloor cross beam on each side is connected to the underfloor longitudinal beam on the same side and the middle channel; and the inclined connecting beams are connected to the left side and the rightside of the middle channel, and the front end of the inclined connecting beam on each side is connected to the underfloor longitudinal beam on the same side, and the rear end is connected to the floorcross beam on the same side and the middle channel. The floor beam structure applied to the vehicle provided by the invention has more force transmission channels, so serious deformation of a floor generated when the vehicle suffers impact can be avoided.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a floor beam structure for vehicles. Background technique [0002] Vehicles in related technologies, such as pure electric vehicles, have a relatively low floor structure, and the floor structure is similar to that of traditional vehicles with engines. There is not much space for battery layout, which affects the cruising range of the vehicle. At the same time, the batteries of general pure electric vehicles are arranged under the floor. When the vehicle collides, such as a frontal collision or a side collision, there are fewer force transmission channels, and the floor and the beams on the floor are seriously deformed, which excessively squeezes the battery installation space. It is easy to detonate the battery and cause a fire. In addition, the strength of the traditional floor is weak, and it cannot absorb the collision energy well during a collision, and there is no install...

Problems solved by technology

[0002] Vehicles in related technologies, such as pure electric vehicles, have a relatively low floor structure, and the floor structure is similar to that of traditional vehicles with engines. There is not much space for battery layout, which affects the cruising range of the vehicle

At the same time, the batteries of general pure electric vehicles are arranged under the floor. When the vehicle collides, such as a frontal collision or a side collision, there are fewer force transmission channels, and the floor and the beams on the floor are seriously deformed, which excessively squeezes the battery installation space. Easy to detonate battery fire

In addition, the strength of the traditional floor is weak, and it cannot absorb the collision energy well during a collision, and there is no installation point for the functional modules and powertrain of the new energy vehicle in the cabin, which cannot meet the design requirements of the new energy vehicle
