Description

ROOF PILLAR ASSEMBLY OF 3-DOOR VEHICLE}

The present invention relates to a roof pillar assembly of a three-door vehicle, and more particularly, to a roof pillar assembly of a door vehicle that can not only reduce manufacturing costs but also improve strength.

In general, the roof side outer reinforcement member, together with the center pillar outer reinforcement member, is the most important reinforcement for preventing vehicle body deformation during side impact of the vehicle body. However, in the case of three-door cars, unlike the five-door car, the quarter glass is mounted instead of the rear door, so that the cross section of the rear part of the roof side outer reinforcing member does not form a 'c' and welds with the quarter glass flange of the side outer panel. In order to achieve a 'b' cross section.

Here, the meaning of the letter 'b' or 'c' cross section is more comprehensive, including not only the literal shape but also the modified shape.

The roof pillar assembly of the three-door vehicle will be described in more detail with reference to FIGS. 1 and 2.

1 and 2, the roof pillar assembly of a three door vehicle includes a side outer panel 110 having a quarter glass flange 115 formed thereon; A roof side outer reinforcement member 120 welded to the inside of the side outer panel 110 and configured of a front portion A 'and a rear portion B'; The inner side panel 140 is welded to face the inner side of the roof side outer reinforcement member 120.

The roof side outer reinforcing member 120 is composed of a front portion A 'and a rear portion B' extending rearward from the front portion A 'and welded to the quarter glass flange 115, and thus the side surface of the vehicle body. It serves to reinforce the.

At this time, the front portion (A ') of the roof side outer reinforcing member 120 is formed in the cross-sectional shape of the letter' B 'advantageous to the side impact, the rear portion (B') is easily deformed during side impact 'b' The chair consists of a cross-sectional shape. Therefore, a portion ('neck' portion, N) where the two cross sections of the front portion A 'and the rear portion B' of the roof side outer reinforcement member 120 meet each other is weak in strength to reinforce it. 130 is further welded to the roof side outer reinforcement member 120.

On the other hand, recently, in order to reduce the weight of the roof side outer reinforcing member 120 is generally used as a material of the ultra high tensile strength of 980MPa or more, but in order to use such ultra high tensile steel, the cross-sectional change of the roof side outer reinforcing member 120 should be small. In the case of the roof side outer reinforcing member 120, cross sections of the front portion A 'and the rear portion B' have to be changed rapidly from the letter 'c' to the letter 'b'.

As described above, in the roof pillar assembly of the conventional three-door vehicle, the cross section of the rear portion B 'of the roof side outer reinforcing member 120 is formed in a' b 'shape that is weak in collision performance, and thus separates to reinforce it. Since the reinforcing member 130 must be used, there is a problem in that the manufacturing cost increases.

Accordingly, it is an object of the present invention to provide a roof pillar assembly of a three door vehicle that can not only reduce manufacturing costs but also improve strength.

According to the roof pillar assembly of the three-door vehicle of the present invention, a quarter glass flange formed side outer panel; A roof side outer reinforcing member having a front portion and a rear portion having a 'c' cross-sectional shape to reinforce the side outer panel; A gusset for connecting the roof side outer reinforcement member and the quarter glass flange; A side inner panel provided inside the side outer panel and coupled to the roof side outer reinforcing member and the gusset.

Here, the gusset is the gusset body formed along the longitudinal direction of the quarter glass flange; A first gusset flange bent from one side of the gusset body and coupled to the roof side outer reinforcement member and the side inner panel; It is preferable that the second gusset flange is bent from the other side of the gusset body and coupled to the quarter glass flange.

At this time, the roof side outer reinforcing member is preferably cold press formed of ultra high tensile strength steel of 980MPa or more.

As described above, according to the present invention, both the front and rear sections of the roof side outer reinforcing member are formed in a 'c' shape, so that the strength is improved and the side collision performance is excellent, and the conventional 'neck' There is provided a roof pillar assembly of a three door vehicle, which eliminates the need to add a separate reinforcement member to the part, thereby reducing manufacturing costs.

In addition, since the cross-sectional change of the front and rear portions of the roof side outer reinforcing member is small and can be manufactured using ultra high tensile steel, which is constrained in molding, a roof pillar assembly of a three-door vehicle is provided that can be reduced in weight.

6 to 8 are cross-sectional views showing an assembly process of a roof pillar assembly of a three-door vehicle according to the present invention.

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

As shown in FIGS. 3 to 5, the roof pillar assembly of the three-door vehicle according to the present invention includes a side outer panel 10 having a quarter glass flange 15, a front portion A, and a rear portion B. Gusset for connecting the roof side outer reinforcing member 20 configured to reinforce the side outer panel 10 and the rear portion B of the roof side outer reinforcing member 20 and the quarter glass flange 15. Gusset 30, and the inner side of the side outer panel 10 is provided with a side inner panel 40 is coupled to the roof side outer reinforcing member 20 and the gusset (30).

The quarter glass flange 15 is a place for the quarter glass to be seated and coupled, and is formed in the side outer panel 10.

The roof side outer reinforcement member 20 is formed to be long in the longitudinal direction of the loop and is welded to the side outer panel 10, and extends rearward from the front portion A and the front portion A, and thus the quarter glass flange 15. ) And the rear portion B adjacent to the.

The cross section of the front portion A and the rear portion B of the roof side outer reinforcing member 20 is formed in a 'c' shape. As described above, unlike the prior art in which the cross section of the rear portion B of the roof side outer reinforcing member 20 has a 'b' shape, in the present invention, both the front portion A and the rear portion B are 'c'. By having the shape of the magnetic cross section, the strength is improved, which is very advantageous for the side impact performance. On the other hand, since the cross-sectional changes of the front portion A and the rear portion B of the roof side outer reinforcement member 20 are smaller than in the prior art, the roof side outer reinforcement member 20 can be cold press-molded with ultra high tensile steel of 980 MPa or more. In addition, the weight reduction can be achieved and the manufacturing cost can be reduced.

In addition, the cross-section of the rear portion (B) of the roof side outer reinforcing member 20 is made of a 'C' shape resistant to collision, so that a separate reinforcing member 130 to reinforce the conventional 'neck' portion (N) is There is an unnecessary advantage.

Here, the rear portion B of the roof side outer reinforcement member 20 is formed in a 'c' cross-sectional shape and cannot be connected to the quarter glass flange 15, in which case the rear portion of the roof side outer reinforcement member 20 is formed. It is the gusset 30 that connects B) to the quarterglass flange 15.

The gusset 30 has a gusset body 33 formed along the longitudinal direction of the quarter glass flange 15, and is bent from one side of the gusset body 33 so that the roof side outer reinforcing member 20 and the side inner panel 40 are provided. The first gusset flange 31 is coupled to, and the second gusset flange 32 is bent from the other side of the gusset body 33 is coupled to the quarter glass flange (15).

Here, the shape of the gusset 30 is made of a 'c' shape, it is good to ensure that the rear portion (A) of the roof side outer reinforcing member 20 is sufficiently connected to the quarter glass flange (15). At this time, the shape of the gusset 30 is not limited to this if the rear portion B of the roof side outer reinforcing member 20 can be sufficiently connected to the quarter glass flange 15.

By such a configuration, a process of assembling the roof pillar assembly of the three-door vehicle according to the present invention will be described with reference to FIGS. 6 to 8 schematically.

First, the first gusset flange 31 of the gusset 30 is positioned at the end of the rear portion B of the loop side outer reinforcing member 20 as shown in FIG. 6, and then the contact surface is welded to form a gusset ( 30) and the roof side outer reinforcing member 20 are integrally combined.

Subsequently, as shown in FIG. 7, the side outer panel 10 is positioned outside the gusset 30 and the roof side outer reinforcing member 20 welded to each other, and the quarter glass flange 15 is then gusseted ( The contact surface is welded to engage the second gusset flange 32 of 30.
