Description

  The present invention relates to a side body structure of a vehicle, and more particularly to a side body structure of a vehicle provided with a hinge mounting portion for mounting a door hinge to a hinge pillar reinforcement.

Conventionally, on a vehicle body side portion of a vehicle, a hinge pillar that vertically connects a front end portion (a side end portion of a front header) of a roof side rail extending in the front-rear direction and a front end portion of a side sill extending in the front-rear direction, and the hinge pillar A front pillar connected to the upper end is provided.
Since the hinge pillar constitutes the front side portion of the peripheral part of the passenger entrance / exit, a pair of upper and lower door hinges for pivotally opening and closing the front door with respect to the passenger entrance / exit is a hinge pillar reinforcement (hereinafter, hinge). (Abbreviated as pillar rain).

The hinge pillar is disposed so as to face the rear side in the front-rear direction with respect to the front wheel.
Therefore, when a collision in front of the vehicle body occurs, the front wheel moves backward due to the collision load, and therefore, a collision load that is not relieved in impact may act on the vehicle body side through the retracted front wheel.
In a small overlap collision (hereinafter abbreviated as SOL collision), the collision object and the front side frame do not overlap. Therefore, when the retracted front wheel interferes with the hinge pillar, an occupant such as a hinge pillar is caused by the collision load input from the front wheel. There was a risk that the surrounding passenger compartment space would be deformed. In particular, when the vehicle width needs to be increased due to design requirements, the hinge pillar is disposed on the outer side in the vehicle width direction than usual, so that the front wheel tends to interfere with the hinge pillar at the time of collision. Therefore, a technique for preventing the deformation of the passenger compartment space due to a collision load from the front wheels has been proposed.

  The side body structure of a vehicle disclosed in Patent Document 1 includes a hinge pillar having a pillar outer panel including a front wall surface and a pillar inner panel that forms a closed section extending in the vertical direction in cooperation with the pillar outer panel, and is disposed within the closed section. A hinge pillar rain including an inclined surface and guide means for guiding the front wheel to the rear rear outside in the event of a collision. The guide means forms an angle between the inclined surface and the side wall surface between the front wall surface and the side wall surface. It is comprised so that it may set smaller than an angle. Thereby, at the time of SOL collision, the front wheel can be guided from the inner side in the vehicle width direction to the outer side, and the collision load can be released to the outer side in the vehicle width direction.

Has been.

Next, functions and effects of the side body structure of the vehicle V will be described.
For example, in the initial stage of the small overlap (SOL) collision, the collision load acts on the front wheel 9 and the lower arm (not shown) curves to the rear side, so the front wheel 9 starts to move backward, and the upper half of the spoke 9a The peripheral wall collides with the front vertical wall 16b.
Since the peripheral wall portion of the spoke 9a is formed in an inclined shape so as to move rearward toward the left side, it comes into contact with the inclined surface of the front vertical wall portion 16b in a plan view.

As the spoke 9a retreats, the lower hinge mounting portion 16 is crushed and deformed to the right, so that the contact portion between the spoke 9a and the front vertical wall portion 16b gradually moves to the left rear, and the spoke 9a moves to the rear. The front wheel 9 starts to rotate counterclockwise around the contact portion while moving leftward.
As shown in FIG. 11, in the initial stage of the collision, the vicinity of the lower hinge mounting portion 16 is lower in strength than the upper portion of the lower hinge mounting portion 16. The part 16 is preferentially deformed to absorb the collision load.

In the middle stage of the collision, the rim 9b and the hinge pillar rain 11 collide, and the hinge pillar rain 11 starts to deform.
The contact portion between the front wheel 9 and the hinge pillar rain 11 gradually moves rearward, and the front wheel 9 further rotates counterclockwise around the contact portion that has moved rearward.
In the late stage of the collision, the front wheel 9 is detached from the vehicle body side, and the contact state between the front wheel 9 and the hinge pillar rain 11 is released. Thereby, the deformation amount of the hinge pillar 10 due to the interference with the front wheel 9 is suppressed, and the deformation of the passenger compartment space due to the collision load via the front wheel 9 is prevented.

According to the side body structure of the vehicle V, the vicinity of the lower hinge mounting portion 16 in the hinge pillar 10 is configured to be lower in strength than the upper portion of the lower hinge mounting portion 16. It is not necessary to configure the hinge pillar rain 11 to have a high strength that can withstand a collision load, including the vicinity, and the weight of the hinge pillar rain 11 can be reduced.
Further, since the lower hinge mounting portion 16 can be deformed by a collision load from the front wheel 9, when the collision load is input from the front wheel 9, the lower hinge mounting portion 16 is deformed while suppressing deformation of other parts. The front wheel 9 that moves backward can be guided outward in the vehicle width direction.

  Since the vicinity of the lower hinge mounting portion 16 is deformed by the collision load when the collision load is input from the front wheel 9, the front wheel 9 moving backward with a simple configuration can be easily guided to the outside in the vehicle width direction.

  The lower end portion of the side wall portion 11 a of the hinge pillar rain 11 is provided in the vicinity of the lower end side of the lower hinge attachment portion 16, and the lower end portion of the right side portion of the front wall portion 11 b of the hinge pillar rain 11 is the lower hinge attachment portion 16. Since it is provided at a position above the lower end portion, the deformation of the lower hinge mounting portion 16 can be promoted with a simple configuration, and the retreating front wheel 9 can be reliably guided outward in the vehicle width direction.

  The front vertical wall portion 16b of the lower hinge mounting portion 16 is disposed so as to face the upper half of the front wheel 9 in the front-rear direction and is formed to be inclined so as to move rearward as viewed from the side. Therefore, the front side vertical wall portion 16b can form a contact portion with a large area with the inclined portion of the front wheel 9 to increase the load transmission efficiency, and promote the guidance of the front wheel 9 moving backward in the vehicle width direction with a simple configuration. be able to.

Next, a modified example in which the embodiment is partially changed will be described.
1) In the above embodiment, an example in which the hinge pillar rain and the hinge pillar rain lower are separately formed has been described. However, the hinge pillar rain and the hinge pillar rain lower are integrally formed as a single hinge pillar rain. Also good.
In this case, after the hinge pillar rain including the lower hinge mounting portion is pressed, the composition of the lower hinge mounting portion and the vicinity thereof is changed by applying predetermined heat treatment to the lower hinge mounting portion and the vicinity thereof. Then, the strength of the lower hinge mounting portion and the vicinity thereof is lowered than the strength of the other portions.

2) In the above embodiment, the example in which the hinge pillar rain is formed of high-tensile steel has been described. However, at least the vicinity of the lower hinge mounting portion is configured to have lower strength than the upper portion of the lower hinge mounting portion. The material of the hinge pillar rain can be arbitrarily selected.

3) In addition, those skilled in the art can implement the present invention with various modifications added without departing from the spirit of the present invention, and the present invention includes such modifications. is there.
