Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle front pillar structure, and more particularly to a front pillar structure in which a line hose is arranged in a closed cross section of a front pillar outer and a front pillar inner.

[Conventional technology]

Conventionally, as a front pillar structure of a vehicle front portion, for example, as shown in FIG. 3, a front cross section of a front pillar outer 20 and a front pillar inner 30 are abutted and joined to each other to form a closed cross section. A line hose 40 is arranged and connected so as to partition the closed cross section. The front pillar 10 is strengthened by connecting and disposing the line hose 40, and the rigidity thereof is ensured.

As a front pillar structure shown in FIG. 3, there is Japanese Utility Model Publication No. 62-145779 (Japanese Patent Application No. 61-30555).

[Problems to be solved by the device]

However, in such a front pillar structure, since the front pillar 10 has a strong structure to secure rigidity by disposing and connecting the line hose 40, collision energy is applied to the front pillar 10 at the time of a vehicle collision or the like. In this case, the front pillar 10 was not easily deformed, and the collision energy could not be sufficiently absorbed.

Then, the subject of this invention is that a front pillar can fully absorb collision energy.

[Means for solving the problem]

Therefore, the present invention provides a front pillar structure in which a closed cross section is formed by a front pillar outer and a front pillar inner, and a line hose is arranged and coupled so as to partition the closed cross section. In addition to forming the bead portion, the bead portion is formed by being offset in the vehicle front-rear direction.

[Action]

According to the above-mentioned means, when the vehicle collides, each bead portion of the front pillar is deformed, and the collision energy can be sufficiently absorbed, and each bead portion is offset in the vehicle front-rear direction. Therefore, for example, the front pillar outer, the line hose, and the front pillar inner can be gradually deformed in order to absorb energy.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show an embodiment of the present invention. FIG. 1 is a sectional view taken along the line II of FIG. 2, and FIG. 2 is a perspective view of a front pillar portion of a vehicle.

As shown in FIG. 1, the front pillar 1 shown in FIG. 2 has a closed cross section formed by a front pillar outer 2 located outside the vehicle and a front pillar inner 3 located inside the vehicle. In this closed cross section, a line hose 40 is arranged and coupled so as to be located in the approximate center and partition the closed cross section into a plurality of spaces.

With such a front pillar structure, the front pillar outer 2 has a bead portion that is concave inward in the vehicle width direction.
21 is formed, a convex bead portion 31 is formed on the outer side in the vehicle width direction on the front pillar inner 3, and a bead portion 41 that is concave on the inner side in the vehicle width direction is formed on the line hose 4. Are formed. Furthermore, this each bead part 2
1, 31, 41 are formed by being offset in the vehicle front-rear direction.

Specifically, for example, the concave bead portion 41 of the line hose 4
With reference to, the concave bead portion 21 of the front pillar outer 2 is formed to be offset to the vehicle rear side by the distance a, and the convex bead portion 31 of the front pillar inner 3 is formed to the vehicle front side. It is formed by being offset by b.

As shown in FIG. 2, each of the bead portions 21, 31, 41 has a front pillar belt line portion 11 and a rocker joint portion.
Between 12 and 12, it is formed so as to extend in a direction substantially perpendicular to the vehicle front-rear direction.

With the above configuration, when the vehicle collides, the collision force F is applied to the front pillar 1, but the bead portions 21, 31, 41 of the front pillar 1
By deforming, the collision energy is sufficiently absorbed. Further, since the respective bead portions 21, 31, 41 are offset in the vehicle front-rear direction, the respective constituent members 2, 3, 4 of the front pillar 1 are not deformed at the same time, and the front pillar inner 3, the line hose 4, The front pillar outer 2 is gradually deformed in order to absorb the collision energy.

Therefore, the front pillar 1 can sufficiently absorb the collision energy and also gradually absorb the collision energy.

Further, since the absorbing structure is simply provided with the concave or convex bead portion, its molding can be simplified.

Furthermore, since each bead portion 21, 31, 41 is formed in a direction substantially at right angles to the vehicle front-rear direction, collision energy can be effectively absorbed.

In the above embodiments, one bead portion is formed on each panel, but the present invention is not limited to this, and a plurality of bead portions may be formed in the vehicle front-rear direction. .

 Moreover, the shape of the bead portion may be an uneven shape.

Furthermore, the offset bead portions have been described with reference to an example in which the front pillar inner, the line hose, and the front pillar outer are formed in this order. You can go.

[Effect of device]

As described above, according to this invention, the front pillar outer, the front pillar inner, and the line hose are provided with the bead portions offset in the vehicle front-rear direction, so that the collision energy of the vehicle is gradually absorbed by the deformation of each bead portion be able to.
