- FIG. 4C is a cross-sectional view taken along the line DD of FIG. 4A, schematically showing the front header portion according to the second embodiment of the present invention.
- FIG. 5 is an explanatory view showing a centroid position of a front header portion according to a second embodiment of the present invention when a lateral force is applied.
- FIG. 1 shows an automobile 12 including a front header portion 22 according to the first embodiment of the present invention.
- FIG. 2 shows a specific structure of the front header portion 22.
- a front header portion 22 located at the front portion of the roof 14 of the automobile 12 is given.
- the front of the vehicle is indicated by an arrow FR
- the upper part of the vehicle is indicated by an arrow UP
- the outer side in the vehicle width direction is indicated by an arrow OUT.
- the front header section 22 has a pair of upper and lower header upper panels 24 and a header lower panel 26 that connect the front pillars 16 of the automobile.
- the header upper panel 24 and header opening channel 26 are!, And the deviation is curved so as to protrude upward according to the shape of the roof 14, In addition to improving the strength against the load from above, the cabin can be secured widely.
- the header upper panel 24 is formed with a bead 28 continuous in the vehicle width direction.
- the bead 28 is configured by partially projecting the header upper panel 24 downward in the vehicle longitudinal direction center of the header upper panel 24.
- the cross section of the bead 28 is substantially rectangular.
- the depth of the bead 28 is deepest at the center in the vehicle width direction so as to be divided. It gradually decreases toward both ends in the vehicle width direction.
- the protruding end (lower end) of the bead 28 is in contact with the header lower panel 26 at the center in the vehicle width direction, and this contact portion is the joint 30, and the bead 28 and the header lower panel 26 are joined. ing.
- the header upper panel 24 is reinforced by the beads 28, and the front header portion 22 as a whole is also reinforced. Therefore, the front header portion 22 can be reliably reinforced with a simple structure in which only the beads 28 are provided, and inadvertent deformation against external force can be prevented.
- FIG. 3 shows a centroid position T1 of the front header portion 22 provided with the beads 28 as in this embodiment, and a front header portion without the beads 28 as a comparative example (except for the absence of the beads)
- the centroid position T2 of the front header in the same configuration as that of the form is indicated by a two-dot chain line. From FIG. 3, it can be seen that the centroid position T1 of the front header portion 22 of the present embodiment having the beads 28 is lowered with respect to the centroid position T2 of the front header portion without the beads 28.
- a lateral force F acts on the front header portion 22 is considered. Since the front header portion 22 is convexly curved upward, a bending moment acts on the center of the front header portion 22 in the vehicle width direction. This bending moment is the distance between the line connecting both ends of the front header 22 (line of action L of lateral force F) and the centroid position Tl, ⁇ 2 (distance at the center in the vehicle width direction, ⁇ 1, (indicated by ⁇ 1). Therefore, as described above, in this embodiment in which the centroid position T1 of the front header portion 22 is lowered, the bending moment is reduced as compared with the configuration in which the centroid position ⁇ 2 is not lowered as shown in FIG. Buckling It can be prevented more reliably.
- ⁇ 2 F / A + F ⁇ 2 ( ⁇ 2 ⁇ ⁇ ) / ⁇ 1
- ⁇ 1 F / A + F61 ( ⁇ l-d) / EI
- FIG. 4 shows a front header 62 according to the second embodiment of the present invention.
- the shape of the bead 68 is different from that of the first embodiment, but the other configuration is the same.
- the same components and members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
- the bead 68 of the second embodiment contacts the header lower panel 26 over the entire vehicle width direction. As such, its shape is determined.
- the front header 62 is reinforced by a simple structure with the beads 68 to prevent inadvertent deformation due to an external force. It is possible.
- the beads 68 are joined to the header lower panel 26 by a larger number of joining portions 30, so that the reinforcement can be effectively performed.
- the number of manufacturing steps can be reduced.
- the configuration in which the bead 28 or the bead 68 protrudes downward from the header upper panel 24 is described, but the configuration for reinforcing the front header portion 22 is not limited thereto.
- the bead 28 is protruded upward from the header upper panel 24, it is reinforced as compared with the configuration in which the bead 28 is not provided.
- the header lower panel 26 provide a bead that protrudes upward and a bead that protrudes downward.
- the bead protruding downward is provided in the header lower panel 26, it becomes difficult to secure a large vehicle interior.
- a bead protruding upward is provided in the header upper panel 24 or the header opening 26, the centroid position is also increased. Therefore, as described above, in order to lower the centroid position of the front header part and ensure the reduction in stress when the lateral force F or the like is applied, the bead protruding downward is attached to the header upper panel. 24 is preferably provided.
- the application target of the present invention is not limited to the front header portion 22 described above.
- the roof header structure of the present invention can be applied to a roof header portion composed of a plurality of header panels, as is the case with the rear header portion 32.
- header panels constituting the roof header section is not limited to the above two (header upper panel 24 and header lower panel 26).
