う問題点があった。However, since the lower end portion 19 of the door panel has a small amount of wrap with respect to the side sill 13, the load is not sufficiently transmitted from the door body to the side sill 13 of the vehicle body frame for side input. FIG.
As shown in (b), a load acts on the upper end of the side sill 13, and since the side sill 13 is joined to another member only at the lower end, when the side sill 13 rotates, the energy of the side sill 13 itself is increased. Since the absorption efficiency is lowered, there is a problem that the plate thickness must be increased to prevent this.

As shown in FIG. 3, the invention relates to a skeletal structure such as the side sill 3 and the center pillar 4 in the vehicle body structures 1 and 2.
FIG. 2 shows an enlarged view centering on the joint between the side sill 3 and the center pillar 4. As shown in FIGS. 2 and 3, in the vehicle body frame structure, the side sill 3 including the side sill inner 6 and the side member 5 and the side member 5 serve as a front-rear direction member, and the outrigger 7 is provided between the side sill inner 6 and the side member 5. Are arranged as lateral members. The side sill inner 6 and the side sill 3 are formed separately or integrally by aluminum extrusion molding or the like. The outer side surface of the side sill 3 has a groove portion 11, and as shown in FIG. 4, the center pillar 4 is arranged on the outer side thereof and is joined at the lower end portion of the side sill 3.

In order to explain the function and effect of the embodiment of the present invention, the side collision barrier 14 is shown in FIG. 5 together with the present embodiment. Doors (inner panel 9, outer panel 10) from the side of the vehicle during a side collision
Input acts on. As a result, the lower end of the inner panel 10 is deformed and moved, and the convex portion 12 fits into the groove portion 11 of the side sill 3, so that the vehicle body skeleton is efficiently formed through the door (inner panel 9, outer panel 10). The load is transmitted to the side sill 3 and the side sill inner 6. Further, since the panel portion is deformed by the above fitting in the space portion formed by both the panels 9 and 10 of the door, not only the efficiency of load transmission to the side sill 3 and the side sill inner 6 is improved, but also the energy is absorbed by the door panel itself. .

In addition, the outrigger 7 is arranged as a lateral member so as to match the lower end of the side sill inner 6. Therefore, when the deformation of the side sill 3 and the side sill inner 6 progresses, as in the case of the body structure of the general vehicle (conventional example) shown in FIG.
3 does not rotate and the energy absorption efficiency due to the deformation of the side sill 13 itself does not deteriorate, the side sill outer 3 does not rotate and the deformation progresses, and further, the load is transmitted to the outriggers 7, the door panels 9, The load can be efficiently transmitted by the 10, the side sill 3, the side sill inner 6, and the outrigger 7 to absorb energy.

伝達でき前述したように効率的に受けることができる。Further, as shown in FIG. 7, when an input is received from the side, the center pillar outer 15 starts to deform. In the present embodiment, the center pillar 4 including the center pillar inner 16 and the center pillar outer 15 is joined to the outside of the side sill outer 3, and the lower end of the center pillar 4 is located at the lower end of the side sill outer 3. There is. Therefore, since the joint portion of the center pillar 4 is not located at the lower end portion of the side collision barrier 14 that maximizes the input load, that is, the upper surface of the side sill 3, the joint portion between the center pillar 4 and the side sill 3 and the side sill inner 6 is not formed. The damage can be prevented, and the input load can be reliably transmitted from the center pillar 4 to the side sill 3 and the side sill inner 6 which are the skeleton of the vehicle body, so that the input load can be efficiently received as described above.

室内への侵入を防ぐ。FIG. 8 shows a second embodiment. In the second embodiment, in addition to the first embodiment, the outer panel shape of the side sill 3 has an upper portion 35 with the groove portion 11 as a boundary.
The outer surface of the lower part 36 is located outside the outer surface of the lower part 36. Therefore, as shown in FIG. 8, when a gap is created between the door (outer panel 9, inner panel 10) and the side sill 3, mud and dust 17 from below the vehicle body are located below the groove 11 of the side sill 3. Only adheres to 36 and prevents entry into the passenger compartment.

It is possible to prevent mud from adhering to the pants 18 and bringing it into the passenger compartment.
