Embodiment Construction

[0017] An embodiment of the present invention will be described below with reference to the accompanying drawings.

[0018] The vehicle floor 1 includes substantially flat front portions 2 and rear portions 3, a middle portion 4 between the front portions 2 and the rear portion 3, and a tunnel portion 5 formed in the transverse middle portion and extending longitudinally.

[0019] The middle part 4 slopes downwards from the front part 2 towards the rear part 3 which is arranged below the front part 2 in level. Furthermore, the passage portion 5 having a top-hat-shaped cross section is formed in such a manner as to extend in the longitudinal direction of the vehicle. In addition, the floor panel 1 is formed in such a structure that it is substantially symmetrical with respect to the tunnel portion 5 in the lateral direction of the vehicle.

[0020] Curved portions 10 , 11 protruding downward in the form of spherical surfaces are formed on the front portion 2 . In addition, cu...

Abstract

A vehicle floor panel has curved portions formed thereon and protruding downwardly in a spherical fashion, and each of which is surrounded by a substantially horizontal portion. Ribs extending from the curved portions to a vertical wall portion of a tunnel portion and protruding upwardly are provided. Ribs extending between the curved portions and protruding downwardly are also provided. Furthermore, ribs protruding upwardly are provided. According to the construction, the rigidity of various types of vehicle floor panels can be enhanced in an ensured fashion.

Description

[0001] Cross References to Related Applications [0002] This non-provisional application incorporates the subject matter of application No. 2002-379696 filed in Japan on December 27, 2002, and claims priority based on the Japanese application. technical field [0003] The invention relates to a vehicle floor structure. Background technique [0004] Automobile floor structure components such as those described in Japanese Patent Publication JP-A-2000-255454 are known, and such components are highly rigid. [0005] The bottom plate structural member in the above related art has a plurality of curved portions each having a downwardly protruding curved surface. In addition, the floor structural part has upwardly protruding beads formed in such a way as to extend from the curved portion to a flat design portion around the periphery of the curved portion. According to the configuration of the floor structural member, the rigidity of the floor structural member is reinforced to ...
