The present invention relates to a vehicle body stiffness reinforcement device, and more particularly, by sufficiently absorbing the impact force concentrated in the side seal during the side impact of the vehicle and at the same time increasing its own rigidity, the amount of impact applied to the human body, particularly the pelvis The present invention relates to a vehicle body stiffness reinforcement device for reducing the pelvis value to 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 Deformation occurs to the upper part of the door and the roof, and this causes a problem in that the Pelvis value corresponding to the pelvis is not good.

In the conventional body stiffness 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 fused to each other, the reinforcement panel 13 is coupled to the space (10a) to protect the passengers by shock absorption through deformation during side impact 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. have.

If the vehicle deformable Barrier (commonly abbreviated as MDB) 100 collides with the vehicle body configured in this way, the out panel 11 of the side seal 10 and the box of the mermaid panel 12 The part is crushed and pushed to the interior side. At this time, the reinforcement panel 13 installed and fused in the space portion 10a of the side seal 10 is engaged with the crushed portion to absorb the shock and reduce the body deformation, thereby protecting the passenger.

However, since the reinforcement panel was simply fused to the space of the side seal to reinforce the body rigidity during side impact, the weak impact force can prevent the sliding by only the reinforcement panel and the out panel. When the body skeletal deformation is severe, especially the center pillar, the door and the top of the roof deformation is caused to increase the Pelvis value corresponding to the pelvic portion of the human injury value, there was a problem that can not promote the safety of the passengers.

The present invention is to solve the above problems, an object of the present invention is to further weld the side seal reinforcing means inside the space of the side seal and the mermaid panel to increase the coupling rigidity of the mermaid panel and the center follower panel Rigidity reinforcement means can be used to reduce the body frame, the center pillar and the top of the door roof in the event of a side collision of the car, and the direct or indirect impact force received by passengers in the room is sufficiently absorbed to reduce the human injury. It is to provide a vehicle body rigidity reinforcement device that can reduce the Pelvis value corresponding to the human pelvis, which can be a problem.

A feature of the present invention for achieving the above object, in the reinforcement device for reinforcing the rigidity of the vehicle body when the side of the vehicle, the fusion panel and the fusion panel and the side seal to form a side seal, fixed to the lower panel A center floor panel having grooves formed in a transverse direction and a longitudinal direction to prevent deformation of the bottom panel, and side seal reinforcement means fused to the inner side of the out panel and absorbing impact force in a side impact of the vehicle; It is characterized in that it is configured to include a rigid reinforcement means for reducing the amount of impact penetrating into the room.

Hereinafter, preferred embodiments of the vehicle body rigidity reinforcement device of the vehicle according to the present invention will be described in detail.
