Description

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to Korean Patent Application No. 10-2012-0112023 filed on Oct. 9, 2012, the entire contents of which is incorporated herein for all purposes by this reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a connecting structure of a fender apron, and more particularly, to a connecting structure for a fender apron that can disperse an impact load when a vehicle collides.
2. Description of Related Art
When a vehicle collides head-on, a front side member of the vehicle serves to absorb an impact.
However, according to an investigation, accidents in which the vehicle collides off the front side member occupy 25% of actual accidents in a collision accident.
In the accidents in which the vehicle collides off the front side member, a fender apron serves to transfer an impact load.
A general collision load transferring component is constituted by three units of an under body unit, for example, a front apron member, a side body unit, for example, an A-pillar upper reinforcement unit and a door hinge reinforcement unit, and a cowl unit, for example, a cowl side member.
However, in the case of coupling of the respective units, respective connection sections are not continuous, and thus coupling force is weak, and the respective units are connected to each other by a flange, and as a result, a process for connection needs to be added and a deformation possibility by impact load transferring is high.
The information disclosed in this Background of the Invention section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

FIG. 1 is a perspective view of a connecting structure for a fender apron according to an exemplary embodiment of the present invention, FIGS. 2 and 3 are partial perspective views of the connecting structure for a fender apron according to the exemplary embodiment of the present invention, and FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 2.
FIG. 5 is a perspective view of the connecting structure for a fender apron according to an exemplary embodiment of the present invention and FIG. 6 is a cross-sectional view taken along line VI-VI of FIG. 5.
Referring to FIGS. 1 to 6, a connecting structure for a fender apron according to the exemplary embodiment of the present invention includes a fender apron 10, a cowl side member 20 that has the same cross-sectional shape as a part of the fender apron 10 and is coupled with the fender apron 10, and an A-pillar 30 of which the inside is coupled with the cowl side member.
The fender apron 10 is connected with a side member through a connection member 12, and transfers an impact load transferred from a front side to the A-pillar 30 through the cowl side member 20.
The fender apron 10 has a rectangular closed section on a cross section thereof as illustrated in FIG. 3, and the cowl side member 20 may have a cross-sectional shape of a “U” shape and the cow side member 20 has the same cross-sectional shape as a part of the fender apron 10 in order to smoothly transfer the impact load transferred from the fender apron.
A cowl panel 26 is connected to the cowl side member 20, and the connecting structure for a fender apron according to the exemplary embodiment of the present invention may simplify the number of components and a manufacturing process by integrating a general door hinge reinforcement unit and the cowl side member. That is, the connecting structure for a fender apron according to the exemplary embodiment of the present invention may be configured without the general door hinge reinforcement unit.
The A-pillar 30 includes a side outer panel 34 and an A-pillar upper reinforcement member 32 for reinforcing rigidity of the side outer panel, and the cowl side member 20 is inserted between the A-pillar upper reinforcement member 32 and the side outer panel 34 to increase coupling force and secure rigidity.
The cowl side member 20 includes a front part 22 coupled with the fender apron 10 and a rear part 24 inserted into the A-pillar 30.
As illustrated in FIG. 3, a bulk head 40 may be provided between the front part 22 and the rear part 24 of the cowl side member 20, and the A-pillar upper reinforcement member 32 may be coupled to the bulk head 40.
A coupling groove 28 is formed between the front part 22 and the rear part 24 and the bulk head 40 is seated on the coupling groove 28.
The A-pillar upper reinforcement member 32 is coupled with the bulk head 40 through the coupling groove 28.
The bulk head 40 prevents moisture from being introduced into the inside of the vehicle, reinforces the rigidity of the cowl side member 20, and increases an impact transferring and dispersing effect through coupling with the A-pillar upper reinforcement member 32.
As illustrated in FIG. 4, the A-pillar upper reinforcement member 32 and the cowl side member 20 may be coupled with each other to form the closed section. Therefore, the rigidity of the A-pillar reinforcement member 32 may be increased and the impact load transferred from the cowl side member 20 may be smoothly transferred and dispersed to the A-pillar reinforcement member 32.
As illustrated in FIG. 6, cross-sectional shapes of the fender apron 10, the cowl side member 20, and the A-pillar reinforcement member 32 are continuously formed to increase the impact load transferring and dispersing effect.
As described above, according to the exemplary embodiment of the present invention, in the connecting structure for a fender apron, since the sections among the respective members for transferring the impact load are continuous, a collision load transferring effect is increased in a collision.
Further, the number of components and the manufacturing process can be simplified by integrating the door hinge reinforcement unit and the cowl side member.
