エネルギを吸収することになる。When a side collision of an automobile occurs,
The entire door is pushed inward, and the collision energy is absorbed by the entire portion of the front pillar below the window shoulder portion. Especially, regarding the door hinge attachment portion of the front door, the door hinge portion is deformed or broken. Therefore, the collision energy is absorbed.

Crush deformation of the wheel house portion 4a near the side end portion is significant, and effective collision energy absorption cannot be performed. or,
As for the door hinge portion of the front door, since a steering support beam is attached near the attachment portion of the upper door hinge 6a so as to connect the left and right front pillars, the collision load input to the upper door hinge attachment portion is the steering wheel. Although it is received by the support beam and dispersed and absorbed by the front pillar on the other side, the attachment portion of the lower door hinge 6b cannot receive the input load, and it is difficult to effectively disperse and absorb collision energy. Have challenges.

のである。The peripheral flange portion of the gusset 5 is arranged from the vehicle interior side to the side sill inner 12, the inner flange of the box-shaped reinforcement 23, the front floor 3,
It is attached to the wheel house portion 4a of the toe board 4 by spot welding or the like. Then, the pillar inner surface portion 53 of the gusset 5 is joined to the inner side of the box-shaped reinforce portion 23, so that the pillar-shaped outer force portion 2 and the pillar inner surface portion 53 are provided inside the box-shaped reinforce portion 2.
3 is sandwiched between the front pillar lower part of the closed cross section, the box-shaped reinforcement 23 functions as a separator for reinforcing the closed cross section, and the strength of the front pillar lower part including the mounting part of the lower door hinge 6b is Remarkably improved.
Further, the corner portions of the front end portion of the side sill 1 and the vicinity of the lower part of the front floor 3 and the toe board 4 are firmly connected by the lower corner gusset portion 51, and the front end portion of the side sill 1 is prevented from falling inward due to a side collision load, Further, the corner portion of the front pillar 2 near the mounting portion of the lower door hinge 6b and the wheel house portion 4a are firmly connected to each other by the upper corner gusset portion 55, and the collision load input from the lower door hinge 6b is applied to the upper corner gusset portion. 55 is firmly received, and the lower portion of the front pillar 2 is reinforced by the box-shaped reinforcement 23 and the pillar inner surface 53 of the gusset 5 as described above, and the pillar inner surface 53 and the toe board joint surface. The doubler portion 52 including 54 is located below the lower door hinge mounting portion of the front pillar 2. By joining and reinforcing the corner portion between the portion and the wheel house portion 4a, twisting inward of the lower end portion of the front pillar 2 and collapsing deformation of the wheel house portion 4a due to a collision load are prevented. The collision load is widely dispersed and absorbed by the toe board 4 and the front floor 3, and the collision load input from the mounting portion of the upper door hinge 6a is received by the steering support beam as described above and is dispersed and absorbed by the front pillar on the other side. In combination with this, the collision energy is effectively absorbed in the entire lower portion of the front pillar 2.

Although the example in which 3 is integrally fixed is shown, the pillar inner lower member 22 is extended so as to be directly fixed to the upper edge portion of the front end of the side sill 1, and the bulging portion 23a is formed in the downward extending portion of the pillar inner lower member 22. By doing so, the box-shaped reinforce portion 23 may be integrally configured with the pillar inner lower 22. By doing so, the number of constituent parts can be reduced.

たらし得るものである。As described above, according to the present invention, with an extremely simple structure, sufficient reinforcement is performed from the lower door hinge attachment portion of the lower portion of the front pillar to the connection portion with the side sill, and side impact load is applied. The front end of the side sill and the lower part of the front pillar can be prevented from collapsing or twisting, and the front floor and toeboard parts can be prevented from collapsing and deforming, and can effectively disperse and absorb collision energy. Combined with the fact that it does not take up much space inside the vehicle, it can bring about a great effect in practical use.
