The present invention relates to a side seal reinforcement structure which minimizes the amount of indoor inflow during a vehicle side collision. In particular, an impact beam and a beam bracket for fixing the same are provided on the front side of an outer panel of the side chamber to have sufficient self rigidity during a vehicle side collision. It relates to a side seal reinforcement structure of a vehicle which makes it possible.

In general, while the vehicle body is designed and manufactured to have sufficient rigidity mainly in front of the frontal collision, the aspect of protecting the occupant from the impact of the impact on the side of the vehicle is still insufficient. On the other hand, as the damage that occurs when the side of the vehicle increases and the degree of damage increases, the related laws are strengthened and the importance is gradually recognized due to the external regulations on export vehicles. In view of the present situation, there is a growing need to improve the structure of the vehicle body side structure of the vehicle, in particular, the side seal portion of the lower end of the door, which is one of the most vulnerable parts in the vehicle side collision.

That is, as shown in FIG. 2 of the accompanying drawings, the structure of the side chamber is fused while the side chamber inner panel 11 and the outer panel 12 integrally extending from the bottom panel 10 form a predetermined space with each other. The reinforcement panel 13 is embedded between the inner and outer panels 11 and 12.

However, it can be seen that the existing side seal structure is very fragile to have sufficient support stiffness in the side collision of the vehicle. As a result, the side seal portion is severely pushed toward the interior at the same time as the collision and consequently the occupant He had a problem that the injury to human beings increased.

Accordingly, the present invention has been devised in view of such a point, and the impact beam is arranged across the front side of the outer panel of the side chamber, which is simultaneously fixed by the beam bracket on the reinforcement panel and the beam support plate on the side member. An object of the present invention is to provide a side seal reinforcement structure of a vehicle in which lateral stiffness of the lower part of a vehicle body is prepared in case of a side collision.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is connected to the bottom panel 10, the inner panel 11 and the outer panel 12 and the stiffening panel which is embedded between the inner and outer panels 11, 12 are fused while forming a predetermined space with each other ( In the side-silk structure of the vehicle comprising a 13), the impact beam 14 is disposed across the front of the outer panel 12 in the longitudinal direction of the panel, the outer surface of the reinforcement panel 13 The beam bracket 15 is welded to the inner side of the outer panel 12 so that it supports the rear side of the impact beam 14 and at the same time the outer side of the beam support plate 17 fixed to the side member 16 of the bottom panel bottom. Towards the bottom of the impact beam 14 is extended so that it can support the bottom of the impact beam 14.

In particular, the beam bracket 15 is composed of a c-shaped bent plate body, characterized in that the box-shaped cross-section is formed here in close contact with the horizontal posture between the reinforcing panel 13 and the outer panel (11).

In addition, the outer side of the impact beam 14 is surrounded by a cover molding 18, it is possible to maintain a clean appearance for the beam installation site.

This will be described in more detail as follows.

3 is a cross-sectional view taken along line A-A in FIG. 1 showing a reinforcing structure of a side seal according to the present invention.

Here, reference numeral 14 denotes an impact beam.

The impact beam 14 refers to a hollow pipe having a predetermined length, and is arranged to be parallel to the longitudinal direction of the side chamber while maintaining a predetermined distance from the outer surface of the side chamber, that is, the front surface of the outer panel 12.

This impact beam 14 is preferably of sufficient length to be disposed over the entire length of the side chamber.

Further, reference numeral 15 denotes a beam bracket.

The beam bracket 15 is composed of a plate body bent into a c-shape.

The beam bracket 15 is positioned at the top and bottom middle between the reinforcement panel 13 and the outer panel 12, and is bent and supported on the outer surface of the reinforcement panel 13 by using flanges at both ends and bent bottoms. It can be in close contact with the inner surface of the outer panel 12 by using a portion.

The beam bracket 15 installed as described above constitutes a closed rectangular box-shaped cross section together with the reinforcing panel 13, thereby securing a new buffering area inside the side chamber.

In addition, a shock absorbing member 19 penetrates from the outside to the inner part of the beam bracket 15 and the outer panel 12, and the shock absorbing member 19 is disposed directly in front of the impact beam. It is in close contact with the rear of the (14) has a role to support it.

Further, reference numeral 17 denotes a beam support plate.

One end of the beam support plate 17 is fastened and fixed to the side member 16 on the bottom panel 10 which is located inward of the side chamber, and the other end is moved outward along the outer line of the bottom panel and the bottom of the side chamber from here. It extends and is located at the bottom of the impact beam 14 where it is fused and fixed at the bottom of the impact beam 14.

Accordingly, since the impact beam 14 is supported by the beam support plate 17 at the bottom and supported by the beam bracket 15 through the upper shock absorbing member 19, it can be firmly installed at the front of the side chamber. Since the impact beam 14 is wrapped by the cover molding 18, the impact beam 14 is not exposed to the outside.

Therefore, in the side seal structure of the present invention in which the impact beam is disposed long along the front part of the side seal, and the box-shaped buffer cross section is formed by the beam bracket inside the side seal, the impact during the vehicle side collision is initially initiated by the impact beam. Almost all of them are attenuated, and the first reduced residual impact is subsequently reduced by the side chamber itself deformation and the box-shaped buffer space therein, so the lower and lower side portions of the vehicle body including the side chamber are pushed toward the interior. You can significantly reduce the amount of incoming.

As described above, the present invention reinforces the side seal structure of the lower end of the vehicle body, thereby minimizing the amount of indoor inflow during the collision of the vehicle side, so that the safety of the occupant is maximized.
