Definitions
- a vehicle structure having a roof side rail and a center pillar as described in, for example, Japanese Patent Application Laid-Open No. 2008-37123, a vehicle width direction end portion and a vehicle side portion of a rear header disposed at a rear end of the roof 2.
- a structure in which a frame that joins a vehicle upper end portion of a center pillar erected in the center and joins the joint portion and an underbody is known. According to this vehicle structure, the torsional rigidity of the upper part of the vehicle body can be improved, and sufficient rigidity of the upper part of the vehicle body can be ensured.
- the present invention has been made to solve such a technical problem, and provides a vehicle structure that can change a desired shape when a load is applied and can suppress deformation of a center pillar. For the purpose.
- a vehicle structure according to the present invention is connected to a roof side rail that extends in the vehicle front-rear direction on both ends in the vehicle width direction, and a rear end portion of the roof side rail, and extends in the vertical direction of the vehicle.
- a center pillar, and the roof side rail has a cross-sectional area that is narrowed from the front of the center pillar toward the rear end of the roof side rail.
- the cross-sectional area of the roof side rail is reduced from the front of the center pillar toward the rear end of the roof side rail, the cross-sectional area is reduced when, for example, a collision load acts on the roof side rail.
- the bent portion can be easily bent and deformed.
- the moment input to the center pillar can be reduced, and the deformation of the center pillar can be suppressed.
- a desired shape change can be made when a load is applied, and deformation of the center pillar can be suppressed.
- the center pillar reinforcement for generating the predetermined load can be minimized.
- the cross-sectional area of the roof side rail is continuously reduced over a predetermined length from the front of the center pillar toward the rear end of the roof side rail. In this way, it is possible to suppress a decrease in structural strength due to a rapid reduction in the cross-sectional area.
- FIG. 1 is a perspective view showing a vehicle having a vehicle structure according to the embodiment
- FIG. 2 is a cross-sectional view taken along II-II in FIG.
- the vehicle structure according to the present embodiment is formed by crushing the cross section of the rear end portion 10a of the roof side rail 10 and joining it to the center pillar reinforcing portion 20a in an upper body made of carbon fiber reinforced plastic (Carbon Fiber Replastics Plastics: CFRP).
- CFRP Carbon Fiber Replastics Plastics
- this vehicle structure is arranged on a roof portion of a vehicle and extends in the vehicle front-rear direction on both ends in the vehicle width direction, and a rear end portion of the roof side rail 10.
- the center pillar 20 is connected to the vehicle 10a and extends in the vehicle vertical direction
- the quarter 30 is disposed behind the roof side rail 10 and extends in the vehicle width direction.
- the roof side rail 10, the center pillar 20, and the quarter 30 are joined by welding or the like.
- the roof side rail 10 has a closed cross-sectional structure including a roof side rail outer 11 disposed outside the vehicle and a roof side rail inner 12 disposed inside the vehicle.
- the roof side rail 10 is formed by welding or the like with the roof side rail outer 11 and the roof side rail inner 12 facing each other.
- the roof side rail 10 has a substantially constant cross-sectional area from the front end to the front position P of the center pillar 20, and the cross-sectional area is narrowed from the front position P toward the rear end of the roof side rail 10. .
- the roof side rail 10 has a substantially constant shape and size from the front end of the roof side rail 10 to the front position P of the center pillar 20.
- the section 10 is formed to be gradually smaller so that the cross section is crushed up to a position S just before the joint portion between the center pillar 20 and the center pillar 20. And the part by which the cross section was crushed forms cross-sectional crushing part 10b. As shown in FIG.
- the cross-sectional crushing portion 10b starts to squeeze the cross-sectional area from the near position P, gradually decreases over the length from the near position P to the immediately preceding position S, and is almost completely crushed at the immediately preceding position S. ing.
- the cross-sectional area from the front end of the roof side rail 10 to the front position P is not limited to being substantially constant, and the height from the front end to the front position P may change in the vehicle longitudinal direction. Then, comparing the part from the front end to the front position P and the part from the front position P to the previous position S by the change in the height in the front-rear direction, the part from the front position P to the previous position S is the unit. It is formed so that the amount of change in height per length becomes larger.
- the quarter 30 has a closed section structure with a quarter outer 31 disposed outside the vehicle and a quarter inner 32 disposed inside the vehicle.
- the quarter 30 is formed by welding or the like with a quarter outer 31 and a quarter inner 32 facing each other.
- FIG. 3 and 4 are views for explaining the deformation of the roof side rail when a collision load is applied.
- an arrow F1 indicates the traveling direction of the collision device. From the position P before the center pillar 20 to the position S just before the joint portion between the roof side rail 10 and the center pillar 20 in the initial stage when the collision device advances along the arrow F1 and the collision load acts on the roof side rail 10. Since the cross-sectional area is reduced, the roof side rail 10 is easily broken at the portion where the cross-sectional area is reduced (that is, the cross-sectional crushing portion 10b). Thereby, the input of the moment My to the center pillar 20 can be reduced, and deformation of the center pillar 20 can be suppressed. As a result, a desired shape change can be made when a load is applied, and deformation of the center pillar 20 can be suppressed.
- FIG. 5 is a diagram showing the relationship between device stroke and load.
- the horizontal axis is the device stroke
- the vertical axis is the collision load.
- FIG. 5 by directly supporting the force in the collision device traveling direction with the center pillar 20 in the latter half of the collision, it becomes possible to minimize reinforcement of the center pillar 20 for generating a predetermined load. . Further, by minimizing the reinforcement of the center pillar 20 as described above, it is possible to easily maintain the weight reduction of the vehicle. *
- embodiment mentioned above shows an example of the vehicle structure which concerns on this invention.
- the vehicle structure according to the present invention is not limited to the one described in the above embodiment.
- the vehicle structure according to the present invention may be obtained by modifying the vehicle structure according to the embodiment so as not to change the gist described in each claim, or by applying to another.
