Abstract

The present invention relates to a side seal reinforcement device of an automobile, wherein a center floor panel having a bent portion formed on one side of an in-panel of the side seal is fused, and is supported by a support to increase the coupling rigidity of the side seal rear portion inside the bent portion. The beam is fixed by welding, and the reinforcing member is fused to the inner side of the outer panel of the side seal to absorb the impact force from the front side when the vehicle collides, thereby reducing the amount of indoor penetration at the bottom of the door panel. In addition to minimizing the impact force, it is possible to improve the safety of the passengers by reducing the Pelvis value corresponding to the pelvis of the human injury.

The present invention relates to a side seal reinforcement device of a vehicle, and more particularly, by directly absorbing the impact force at the front of the side seal portion at the time of a side collision of the vehicle and increasing the coupling stiffness of the rear portion, thereby directly or indirectly impacting the passenger. In addition, the present invention relates to a side seal reinforcement device for a vehicle that can minimize the amount of impact applied to the human body, in particular, the pelvis value corresponding to the pelvis, and thereby promote passenger safety.

In general, the vehicle body is an important factor to ensure the safety of the vehicle by testing the front and side impact to ensure the safety of the passenger in the event of a crash, and already in each country It is used as a big item such as import regulation by legalizing.

However, most of the cars produced at present have a certain level of safety against frontal collisions, but the safety level against side collisions is insufficient. As a result, side seals, which are vulnerable to side collisions with other vehicles, are pushed into the interior In addition, deformation occurs to the upper part of the door panel and the roof, and this causes a problem that the Pelvis value corresponding to the pelvis is not good.

In the conventional side seal reinforcing device for complying with the above regulations, as shown in FIGS. 1 and 2, the side seal 10 has a space portion 10a in which the out panel 11 and the in-panel 12 are constant. Are formed to be fusion-bonded to each other, and the reinforcing member 13 is fused to the inner side of the outer panel 11 so as to protect the passengers by shock absorption through deformation during side collision of the vehicle. .

In addition, the front seat cross member 14 is supported on one side of the in-panel 12, and the side member 16 is welded to the bottom of the center follower panel 15 to prevent deformation of the center follower floor panel. .

When a moving collision wall (hereinafter referred to as MDB) collides with the vehicle body configured as described above, the box composed of the out panel 11 and the mermaid panel 12 of the side seal 10 is crushed. It is pushed together indoors. At this time, the reinforcing member 13 mounted and fused in the space portion 10a of the side seal 10 is engaged with the out and in-panel 11 and 12 to be crushed to absorb shock and reduce the deformation of the vehicle body. To protect the passengers.

However, since the reinforcing member is simply fused to the inner side of the outer panel as described above to absorb the impact force during side impact, the weak impact force can be prevented from being pushed only by the reinforcing member and the out panel. As the body skeletal deformation is severe, in particular, the lower part of the upper side seal cannot properly support the lower part of the body, thereby increasing the indoor penetration and thus increasing the Pelvis value corresponding to the pelvic part of the human injury value, thereby preventing passenger safety.

The present invention is to solve the above problems, the object of the present invention is to fix the beam (support) to the support (support) in order to increase the coupling stiffness of the rear portion at the bent portion of the center follower panel, out of the side seal By stiffening the reinforcing member that absorbs the impact force on the inner surface of the panel, the indoor penetration of the lower part of the door panel is reduced during side impact, minimizing the direct and indirect impact force received by passengers, as well as the Pelvis value corresponding to the pelvis of human injury. The present invention provides a side seal reinforcement device for a vehicle that can reduce passengers' safety.

A feature of the present invention for achieving the above object, in the reinforcement device for reducing the indoor penetration amount of the lower side of the door panel is mounted on the side interior during the side impact of the vehicle, fused with the out panel to form a side seal A center follower panel having a bent portion fused to one side of the mermaid panel, a beam fixed to the inside of the bent portion by welding to increase the coupling rigidity of the rear portion of the side seal during side impact, and supporting the beam and preventing separation It is characterized in that it is composed of a support that is fused to the bottom of the center floor panel and the bottom panel, and a reinforcing member that is fused to the inner side of the outer panel to absorb the impact force at the front side of the side seal during side impact.

Hereinafter, a preferred embodiment of the side seal reinforcement device for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a view showing a side seal reinforcing device according to the present invention, the outer side 31 and the in-panel 32 are fused to each other side of the side seal 30 made to have a space portion 30a deformation of the bottom panel The center floor panel 33 in which the bent portion 33a is formed to be fused is prevented, and the rear seal portion of the side seal 30 is increased inside the bent portion 33a of the center floor panel 33. Beam 34 is fixed by welding.

In addition, the support 35 is welded to the bottom of the center follower panel 33 and the in-panel 32 by spot welding so as to support the beam 34 and prevent the separation thereof, and thereby the out of the side seal 30. The reinforcing member 36 is fused to the inside of the panel 31 to be mounted in the space part 30a so as to absorb the impact force at the front part in the event of a vehicle side collision on the inner side of the panel 31, and the reinforcing member 36 has a groove or Square beads 36a are formed.

The side seal reinforcement apparatus of the present invention configured as described above is pushed to the interior side while the out panel 31 of the side seal 30 and the reinforcement member 36 are engaged when the collision wall MDB collides with the side of the vehicle. It becomes. At this time, the cross-sectional area is increased by the rectangular beads 36a formed in the reinforcing member 36, so that the impact force received from the front part can be absorbed to the maximum.

Thereafter, when impact force other than the impact force absorbed by the out panel 31 and the reinforcing member 36 affects the in-panel 32, the center follower panel 33 fused to one side of the in-panel 32 and its As the coupling strength of the rear portion of the side seal 30 is increased by the beam 34 supported by the support 35 inside the bent portion 33a, the amount of the door panel lower end portion penetrating into the interior side according to the impact force is minimized. It can be.

As described above, according to the side seal reinforcement device of the vehicle according to the present invention, the bent portion of the center floor panel to fix the beam to the support in order to increase the coupling rigidity of the rear portion, absorbing the impact force on the inner side of the outer panel of the side seal By stiffening the reinforcement member, the indoor penetration of the lower part of the door panel is reduced during side impact, minimizing the direct and indirect impact force received by the passenger, and reducing the Pelvis value corresponding to the pelvis of the human injury. can do.
