Definitions
- the present invention relates to a rear body structure of a vehicle.
- a pair of left and right rear side frames extending in the front-rear direction are generally joined to the lower surface of the rear floor panel in order to improve the strength of the rear part of the vehicle body.
- the rear side frame is formed in a U-shaped cross section that opens upward, and forms a closed cross section in cooperation with the rear floor panel.
- Patent Document 1 discloses that the axial compression rigidity of the rear side frame on the outer side in the vehicle width direction is set smaller than the axial compression rigidity on the inner side in the vehicle width direction.
- the rear side frame is folded inward (deformed so as to protrude inward in the vehicle width direction) at the time of a rear collision.
- Patent Document 1 it is not desirable to cause the rear side frame to be folded in at the time of a rear collision in terms of energy absorption that sufficiently utilizes the deformation in the front-rear direction of the rear side frame, and there is room for further improvement.
- the bottom reinforcing part a part in which the bottom wall part of the rear side frame protrudes in a V shape is conceivable.
- the bottom reinforcing portion has a symmetrical shape with the top portion having the largest protrusion amount as a boundary. That is, the bottom reinforcing portion has an outer inclined surface portion and an inner inclined surface portion on both the left and right sides with the top portion as a boundary, and both inclined surface portions are formed to be inclined at the same angle.
- the side wall reinforcing portion that protrudes in the cross section of the rear side frame (outward in the vehicle width direction) is formed on the vertical wall portion on the inner side in the vehicle width direction of the rear side frame. Further formation is considered. By forming such a side reinforcing portion, the maximum bending load of the rear side frame can be further improved.
- the maximum bending load of the rear side frame becomes extremely large, but the bending load after reaching the maximum bending load does not increase as expected. It turned out that.
- the side wall reinforcing part is formed on the inner wall in the vehicle width direction, so the maximum bending load is improved, but after the maximum bending load is reached, the side reinforcing part buckles.
- a sufficient bending load could not be secured. That is, it was found that the bending load (reaction force) after reaching the maximum bending load is lower at the vertical wall portion inside the vehicle width direction than at the vertical wall portion outside the vehicle width direction.
- the vertical wall portion on the inner side in the vehicle width direction by the component force toward the inner side in the vehicle width direction among the buckling forces input to the inner inclined surface portion of the bottom surface reinforcing portion described above. Becomes easier to buckle.
- the rear side frame is deformed (inwardly folded) inward in the vehicle width direction, and as a result, a sufficient bending load after the maximum bending load is not secured.
- the present invention has been made in view of the above circumstances, and its purpose is to increase the maximum bending load of the rear side frame and to ensure a sufficient bending load after the maximum bending load. It is to provide a vehicle body structure.
- the present invention provides a rear vehicle body structure including a rear floor panel and a pair of left and right rear side frames provided on the lower surface of the rear floor panel so as to extend in the front-rear direction.

- each rear side frame 1 is a U-shaped member having an opening 14 that opens upward. Then, the opening edge portion of the rear side frame 1 (upper end portions of vertical wall portions 12 and 13 to be described later) is joined to the lower surface of the rear floor panel 2 so as to extend between the rear side frame 1 and the rear floor panel 2 in the front-rear direction. A closed cross section is formed. This closed cross-sectional structure improves the rigidity of the rear part of the vehicle body.

- the top portion 21a of the bottom reinforcing portion 21 is set at a position offset outward in the vehicle width direction with respect to the center in the vehicle width direction of the bottom wall portion 11 of the rear side frame 1. For this reason, in the bottom face reinforcing portion 21, the length in the vehicle width direction of the inner inclined surface portion 21c is set longer than the length in the vehicle width direction of the outer inclined surface portion 21b. In other words, the inclination angle of the inner inclined surface portion 21c is set smaller than the inclination angle of the outer inclined surface portion 21b.
- the inner vertical wall portion 13 of the rear side frame 1 has a side reinforcing portion 22 formed so as to protrude into the cross section of the rear side frame 1 (outward in the vehicle width direction).
- the side surface reinforcing portion 22 has a rising portion 22a extending substantially straight upward from the inner end portion in the vehicle width direction of the bottom wall portion 11 and an upper side from the upper end of the rising portion 22a and inward in the vehicle width direction in a cross-sectional view.

It extends continuously over a predetermined range in the front-rear direction so as to reach.
- the outer vertical wall portion 12 of the rear side frame 1 is formed in a substantially flat surface extending in the vertical direction in a sectional view so as to be convenient for disposing brake-related parts.
- the strength (particularly the bending strength) of the rear side frame 1 is sufficiently increased by the formation of the bottom surface reinforcing portion 21 and the side surface reinforcing portion 22, thereby avoiding the occurrence of buckling at an early stage.
- the energy absorption effect at the time of rear collision of the vehicle is improved.
- forces F1, F2, and F3 shown in FIG. 5 act on each part of the rear side frame 1 as forces for buckling the rear side frame 1. That is, a force F1 directed upward and outward in the vehicle width direction acts on the outer inclined surface portion 21b, a force F2 directed upward and inward in the vehicle width direction acts on the inner inclined surface portion 21c, and a vehicle width direction acts on the rising portion 22a. A substantially horizontal force F3 directed outward is applied.
- the broken line in FIG. 5 shows the rear side frame in a state of being deformed at the time of rear collision.
- the force F2 acting on the inner inclined surface portion 21c acts as a force that causes the rear side frame 1 to be bent inward in the vehicle width direction by a component force directed inward in the vehicle width direction.
- the component force to be bent inward is small.
- the inner vertical wall portion 13 tends to be slightly deformed toward the outer side in the vehicle width direction due to the interaction between this fact and the force F3 toward the outer side in the vehicle width direction acting on the rising portion 22a.
- the rear side frame 1 has its center line extending in the front-rear direction maintained in a substantially straight state, and internal folding is prevented or suppressed.

Shown in As shown by the solid line in FIG. 7, in the above embodiment, the maximum bending load (maximum reaction force) is extremely increased, and the bending load (reaction force) after the maximum bending load is sufficiently secured.
- FIG. 6 shows a comparative example.
- the top portion 21 a of the bottom reinforcing portion 21 is set to a position that substantially coincides with the vehicle width direction center of the bottom wall portion 11 of the rear side frame 1. That is, the vehicle width direction length of the inner inclined surface portion 21c is shortened as compared with the case of FIG. 5, and the inclination angle is increased as compared with the case of FIG. This means that the component force inward in the vehicle width direction of the force F2 acting on the inner inclined surface portion 21c is larger than that in the case of FIG. For this reason, as shown by a broken line in FIG. 6, at the time of rear collision, the inner vertical wall portion 13 is largely deformed toward the inner side in the vehicle width direction as a whole.
