Description

Offset impact absorbtion structure of an automotive side frame

The present invention relates to an offset shock absorbing structure on the side of a vehicle, and more particularly, to an offset shock absorbing structure on the side of a vehicle that is capable of buffering and absorbing the impact force applied to the front of the side portion.

Generally, a pillar portion formed by the side of the vehicle and hinged to a door that opens and closes while connecting the floor and the ceiling of the vehicle to form an exterior with an interior space has a window glass of the front portion of the vehicle, as shown in FIG. 1. A pillar (A) in which the front door is hinged, and a frame (C) forming a frame in which the window glass of the rear part of the vehicle is mounted, and a middle part of the pillar (A, C) are provided. The rear door is made of a center pillar (B) hingedly mounted.

Here, the C-pillar (C) has a structure to protect the body portion of the passenger (D) occupied in the rear seat, but the body of the passenger (D) is located when the collision (Off Set) of the vehicle occurs The impact portion K of the sea pillar C is deformed by a collision impact or a collision occurs due to a secondary passenger's movement due to a collision impact, thereby greatly causing deformation, and thus, There is a problem that the structure does not meet the vehicle safety standards.

Accordingly, the C-pillar (C) inserts a reinforcement into the C-pillar (C) in order to meet the deformation regulations according to the vehicle safety standards in the event of a collision to enhance the stiffness to minimize the deformation caused by the impact while maintaining safety standards As shown in FIG. 2, the rigid inner structure has a side inner panel 1 welded to the side outer panel 2 to form a cross-sectional shape of the box, and thus the side outer panel 2 is formed on the side outer panel 2. Along the cross-sectional shape, the side outer reinforcing member 3 and the inner reinforcing member 4 are welded at regular intervals.

However, such a reinforcing structure inside the C-pillar (C) is empty in the box cross-sectional space formed by the side inner panel 1 and the side outer panel 2, except for the side outer panel (2) portion of the space is empty If the impact is applied to the front of the pillar C from the side of the vehicle, the impact is primarily caused by the reinforcing members 3 and 4 positioned close to the side outer panel 2. However, when a large impact force is applied while deforming the reinforcement members 3 and 4, the impact force is not restrained through the side inner panel 1 that occupies most of the box cross-sectional space inside the pillar C. There is a problem that is transmitted to cause the injury of the passenger (D), of course there is a limit that does not meet the vehicle safety standards.

Accordingly, the present invention has been made in view of the above, and the box cross-sectional space inside the pillar pillar is divided into a plurality of spaces on both sides except the center portion, so that the impact applied to the front of the pillar pillar from the side of the vehicle is increased. Its purpose is to satisfy the vehicle safety standards by double absorbing and mitigating.

According to the present invention for achieving the above object, the box-shaped closed cross section is formed by the side inner panel and the side outer panel welded to the side pillars forming the vehicle body of the vehicle and forming a frame on which the window glass of the rear part is mounted. The side outer reinforcing member and the inner reinforcing member are welded at regular intervals along the cross-sectional shape of the side outer panel, and the inner reinforcing member is padded along the cross-sectional shape of the side inner panel. It is characterized in that the stage is configured by padding on the side outer panel.

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

Figure 3 and Figure 4 is an exploded perspective view and a cross-sectional view of the offset shock absorbing structure of the side of the vehicle according to the present invention, respectively, the present invention forms a frame to which the window glass of the rear portion is formed while forming the vehicle body shape of the vehicle The C-pillar (C) forms a box-shaped closed cross section by the side inner panel 1 and the side outer panel 2 welded thereto, and the side outer reinforcement along the cross-sectional shape of the side outer panel 2. While the member 3 and the inner reinforcing member 4 are welded at regular intervals, the inner reinforcing member 5 is padded along the cross-sectional shape to the side inner panel 1, and one end thereof is the side outer panel. The structure added in (2) is achieved.

Here, the inside reinforcing member (5) is padded along the side inner panel (1) and welded (5a) to form an open welding hole (5a ') for easy welding while strengthening its rigidity, this welding portion (5a) ) And one end is bent to divide horizontally one side space formed by the inner reinforcing member 4 and the side inner panel 1, which are padded on the side outer panel 2, and the inner reinforcing member 4 is padded. The other space formed by the inner reinforcing member 4 and the side inner panel 1 is vertically connected to the welded portion 5a so as to form the first flange 5b and the opposite portion of the first flange 5b. It consists of a second flange 5c, one end of which is slightly bent so as to be positioned at the inner reinforcing member 4 while being divided.

Hereinafter, the operation of the present invention will be described in detail.

The box cross-sectional space formed in the C-pillar C of the present invention is occupied by the side outer reinforcing member 3 and the inner reinforcing member 4 by the space of the side outer panel 2, and is divided into a plurality of spaces. Since the space of the side inner panel 1 is divided by the bent side flanges 5b and 5c of the inside reinforcing member 5, if the impact is applied to the front of the pillar C from the side of the vehicle, First, the reinforcement members 3 and 4 positioned close to the side outer panel 2 absorb the impact applied while being deformed by the impact, and the reinforcement members 3 and 4 are applied by the applied impact. ), Even if the deformation amount is large, the sliding is prevented by both flanges 5b and 5c of the inner reinforcing member 5 welded to the side inner panel 1, and the impact is completely in the space of the C-pillar C. Will be absorbed.

On the other hand, when the impact applied to the pillar C is so large that the reinforcing members 3 and 4 positioned close to the side outer panel 2 are completely deformed and pushed into the side inner panel 1, Both bent side flanges 5b and 5c of the inner reinforcing member 5 provided on the side inner panel 1 restrain both sides of the side outer panel 2 and the reinforcing members 3 and 4. Blocking the push to the side inner panel (1) to absorb the secondary secondary to suppress the deformation as much as possible.

At this time, the welded portion 5a of the inside reinforcing member 5 welded along the long region of the side inner panel 1 has flanges 5b and 5c for blocking the side outer panel 2 and the reinforcing members 3 and 4. Of course, to maintain the rigidity to suppress the deformation of).

As described above, according to the present invention, the side outer portion that is deformed when the impact is applied from the side of the vehicle to the front of the pillar is divided by dividing the space of both sides except the center portion of the box cross-sectional space inside the pillar. Constraining both sides of the panel to prevent it from being pushed toward the side inner panel, thereby absorbing and mitigating the impact to the double, thereby satisfying the vehicle safety standards.
