Problems solved by technology

[0007] However, the technique disclosed in Patent Document 1 only improves rigidity by processing the shape of the floor panel thereby forming flat and curved portions.
Furthermore, the technique disclosed in Patent Document 2 is only to add a member different from the beam located at the lower part of the front panel main body, and to connect the bottoms of the swollen parts of the floor panel with this member.
[0008] That is, the techniques disclosed in Patent Document 1 and Patent Document 2 do not suppress vibration by increasing the rigidity of the floor panel in consideration of the joint relationship between the floor panel and the beams spanning the upper surface of the floor panel.

Abstract

A vehicle lower-part structure having a bottom plate forming a floor surface of a vehicle is provided. A floor tunnel is configured at the center of the bottom plate in a vehicle width direction. The floor tunnel is formed in a manner of protruding upward and extending in the vehicle front-rear direction and has a higher stiffness than the bottom plate. A first cross member is coupled to the floor tunnel. The first cross member extending in the vehicle transverse direction, and has a higher stiffness than the bottom plate. One or more recessed portion (s), which protrude downward and having a curved surface, and formed on the recess portions and upwardly protruding parts are formed in a region of the bottom plate, which is divided by the floor tunnel and the first cross member. A second cross member intersects or crosses at least one of the depressed portions over the divided area. The second cross-member is coupled with the projecting part, which is the at least one of the groove parts, that intersects the second cross-member or cross formed.

Description

technical field [0001] The invention relates to a vehicle substructure having a floor panel forming the floor surface of the vehicle. Background technique [0002] For example, when the floor panel of the vehicle vibrates during driving, it may cause noise in the vehicle interior. Therefore, it is necessary to suppress the vibration by increasing the rigidity of the floor panel. [0003] Patent Document 1 discloses a floor structure of a motor vehicle having a floor panel and a beam spanning the upper surface of the floor panel. This floor panel has a planar part and a curved part swollen downward from the planar part. The curved portion of the floor panel has a seat surface protruding downward, and a vertical wall is formed on the outer periphery of the seat surface. Patent Document 1 discloses that since the seat surface is formed on the curved portion even if the work hole is formed substantially in the center of the seat surface, the rigidity of the floor panel can be...
