The present invention relates to a side seal reinforcement structure of a vehicle, and more particularly, to a side seal reinforcement structure of a vehicle that enables the collision of the bulkhead during side impacts, thereby reducing the skid.

In general, as shown in FIG. 1, a side seal of a vehicle has a box-shaped structure in which a side seal inner 1 protruding toward an interior and a side seal outer 2 protruding toward an outdoor are coupled to each other. Adopted and used.

In addition, the side seal is provided with a bulkhead 3 of a shape fixed to the side seal inner 1 and protruding toward the side seal outer 2 in order to cope with a side collision.

Therefore, the bulkhead 3 supports the deformation of the side seal outer 2 toward the side seal inner 1 by side impact by the bulkhead 3, which is a reinforcement material, and at the same time the bulkhead 3 The collision energy is absorbed while being deformed along with the side seal outer 1.

However, the conventional side seal reinforcement structure has the following problems.

First, as shown in FIG. 2, when other components such as the diaphragm 4 are installed in the side seal inner 1 and the side seal outer 2 to secure the torsional rigidity, it is impossible to install the bulkhead 3. Therefore, it is difficult to design a proper structure for impact by installing only the bulkhead or other components such as a diaphragm to secure torsional rigidity.

Next, in the case where only the bulkhead is installed as shown in Fig. 3, when the side seal outer 2 'and the bulkhead 3' start to be deformed by the collision, they lose the resistance and no longer deform to the collision. There was a problem that it was not possible, and it was impossible to control the collision step by step because of one part.

Accordingly, the present invention is to solve the above-mentioned conventional problems, to provide a side seal reinforcement structure of the vehicle that is capable of effective response to the collision by adopting the bulkhead together with parts such as a diaphragm to secure the torsional rigidity Has its purpose.

As a technical structure for achieving the above object, in the present invention, a side seal inner and a side seal outer are mounted on the side where the floor cross member and the seat rear member bracket are installed, and the inside of the side seal inner and the side seal outer In a side seal reinforcement structure of a vehicle in which a reinforcing member is installed, a diaphragm is mounted at a boundary between the side seal inner and side seal outer, and a first bulkhead is fixed to a side seal outer surface of the diaphragm. By providing a side seal reinforcement structure of the vehicle, characterized in that the second bulkhead is fixed to the diaphragm side surface of the side seal inner.

In the present invention, it is preferred that the second bulkhead has a top wall that is inclined toward the seat rear member bracket.

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

Figure 4 is a schematic cross-sectional view showing a side portion of a vehicle employing a side seal reinforcement structure according to the present invention, Figure 5 is a detailed cross-sectional view showing the main portion of the present invention, the floor cross member 5 and the seat rear member bracket ( The side seal inner 1 is attached to the side where 6) is provided, and the side seal outer 2 is attached to the outside of the side seal inner 2.

The side seal inner 1 has an approximately '??' shape protruding inward and the side seal outer 2 has an approximate '??' shape protruding outward.

The diaphragm 10 is installed in the inner boundary portion between the side seal inner 1 and the side seal outer 2, and the side seal outer 2 side and the side seal inner 1 side of the diaphragm 10 are respectively provided. The first and second bulkheads 20 and 30 having a substantially box shape are fixedly installed. In this case, the first and second bulkheads 20 and 30 are located at a portion where the floor cross member 5 and the seat rear member bracket 6 extend.

The first bulkhead 20 is integrally formed at the edge of one end so that the flange 22 is bent outwardly, and the flange 22 is fixed to the diaphragm 10.

In addition, the first bulkhead 20 has an extended shape such that an end portion, which is an opposite portion of the portion where the flange 22 is formed, is adjacent to the side seal outer 2.

The second bulk head 30 is integrally formed to have a shape in which the flange 32 is bent outward at the side and the lower edge of one side end thereof, and the flange 32 is fixed to the side seal inner 1.                     

In addition, the second bulkhead 30 has a shape in which the end, which is the opposite side of the portion where the flange 32 is formed, extends to be adjacent to the diaphragm 10.

In addition, the second bulkhead 30 is bent such that its upper wall 34 has a predetermined inclination upward toward the side seal inner 1, and the side wall 36 extends to the upper wall 34. do. At this time, the inclined angle is formed so that the upper wall 34 is located at the portion where the seat rear member bracket 6 of the portion adjacent to the side seal inner 1 extends.

In addition, the flange 32 formed on the side wall 36 of the second bulkhead 30 also extends along the end of the side wall 36 to the end of the upper wall 34.

In addition, the shape of the upper extension portion of the flange 32 and the upper extension portion of the side wall 36 is set to be in close contact with the upper edge portion of the side seal inner (1).

FIG. 6 is a schematic view for explaining a method of assembling the parts corresponding to the main part of the present invention. The side seal inner 1 is provided on the left and right sides of the reinforcement assembly in which the first bulkhead 20 is fixed to the diaphragm 10. The side seal inner assembly to which the second bulkhead 30 is fixed and the side seal outer 3 are fixed to be positioned respectively.

7 is an explanatory view of the operation of the present invention, when a side impact occurs, the side seal outer 2 'and the first bulk head 20' are plastically deformed by the impact force, thereby absorbing the primary impact, and then The second bulk head 30 'is plastically deformed by the deformation of the diaphragm 10' to absorb the secondary shock. That is, the collision force can be absorbed step by step through the first bulkhead, the diaphragm and the second bulkhead.

At this time, the collision force (F) transmitted to the second bulkhead 30 'is distributed into a collision load (F1) transmitted to the floor cross member side and a collision load (F2) transmitted to the seat rear member bracket.

Of course, it is desirable to set the thickness and physical properties of the components constituting the present invention differently so as to allow optimal control of the collision force.

In particular, in the present invention, the first bulkhead and the second bulkhead can be mounted in a state where another reinforcing member such as a diaphragm is disposed between the side seal inner and the side seal outer, thereby improving the shock absorbing ability.

As described above, according to the side seal reinforcement structure of the vehicle according to the present invention, all of the first bulkhead, the diaphragm and the second bulkhead are installed between the side seal inner and the side seal outer, so that the plastic deformation stepwise to the side impact. While the shock is absorbed has an excellent effect.

In addition, there is an excellent effect that the collision force transmitted to the second bulkhead is distributed to the floor cross member side and the seat rear member bracket side.
