Description

Cowl structure {COWL STRUCTURE}

The present invention relates to a cowling structure that improves the collision performance.

In general, a vehicle body has a box shape in which various panels and frames are appropriately combined with each other. A vehicle body in which a frame and a body are integrally formed through the above combination is called a monocoque structure.

The order of assembly of the monocoque structure is determined according to the layout of the production line of the vehicle manufacturer. Usually, the front body, the center body, the rear body, the dash and the like are assembled first and the side structure portion is assembled first. And is additionally mounted.

1, the front body structure is provided with front side members 10 in the longitudinal direction on both sides of the lower portion of the engine room, and the front side members 10 and the fender are provided with an upper run member 20 A front strut portion 30, and a dash panel 40 separating the engine compartment and the passenger compartment from each other.

A cowl portion (50) is provided on the upper portion of the dash panel (40). The cowl portion 50 is connected to the cowl front panel 51, the cowl center panel 52, the cowl rear panel 53, and the supporting member 54 with the opening 50a opened upward.

Both ends of the cowl portion 50 thus formed are joined to the front strut portion 30 by being joined thereto.

However, the cowl portion 50 of the front body structure described above is insufficient in securing the rigidity of the vehicle body due to the open structure formed along the opening 50a formed for enhancing the pedestrian junction structure and the pedestrian protection structure As a result, the impact force transmitted to the cowl portion 50 at the time of a vehicle collision is reduced, thereby increasing the injury value of a passenger.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cowl structure capable of improving collision performance by improving rigidity of a cowl portion by improving cowl structure and improving coupling structure.

According to an aspect of the present invention, there is provided a cowl structure provided on a dash panel of the present invention, wherein both ends of the cowl are coupled to a front strut, A cowl front panel connected to the front of the center panel and forming a front surface; a cowl rear panel connected to a rear side of the cow center panel and forming a rear surface; and a support member connected to the cowl rear panel, A front rail is coupled to the front surface of the cowl front panel, and the front surface of the cowl front panel is formed as a closed end surface of a "K" shape.

And an end portion of the front rail is coupled to the front strut portion.

A rear rail is coupled to one surface of the cowl rear panel, and the cowl front panel and the rear rail are formed as closed ends of a "K" shape.

The end portion of the rear rail is coupled to the A-pillar portion provided on the vehicle rear side of the front strut portion.

According to the present invention, it is possible to increase the stiffness of the cowl portion by attaching the front and rear rails so as to form a closed end face of the cowl in front and rear of the cowl portion, So that the safety of the passenger can be enhanced.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

In describing the present invention, the same reference numerals are used for the same components as those described in the prior art, and redundant description is omitted.

The cowling structure 100 according to the present invention is characterized in that the front and rear rails are attached to the cowl front panel 120 and the cowl rear panel 130 so as to form a closed end face, It is a technology that can be improved.

The cowling structure 100 according to the present invention is installed on the upper part of the dash panel 40 separating the engine compartment and the car interior and has a U-shaped cross-sectional shape having an opening 100a.

That is, the cowling structure 100 of the present invention includes a cowl center panel 110 provided on the dash panel 40 and forming a bottom surface, a cowl front panel 110 connected to the front of the cowl center panel 110 and forming a front surface, A cowl rear panel 130 connected to the rear of the cowl center panel 110 and forming a rear surface thereof and a supporting member 140 connected to the cowl rear panel 130.

The cowl center panel 110 is attached to the upper portion of the dash panel 40 and the cowl front panel 120 and the cowl rear panel 130 are connected to the front and rear sides.

The cowl front panel 120 is vertically connected to the front of the cowl center panel 110 in an upward direction and has both ends connected to the outer circumferential surface of the front strut 30.

Here, a front rainfall 150 for increasing the rigidity of the cowl front panel 120 is provided on one side of the cowl front panel 120, preferably on the inner side (the side facing the rear side of the vehicle) (150) is coupled with the cowl front panel (120) to form a closed end face of a "K" shape.

That is, the cowl front panel 120 having the 'a' cross-sectional shape is combined with the front rainbow 150 having the 'a' cross-sectional shape to form the closed end of the 'ㅁ' shape, 'Box structure, it is possible to improve the collision performance by increasing the front rigidity of the cowl portion.

Both ends of the front rail 150 are coupled to the upper surface of the front strut 30 so that an impact force transmitted from the front side member 10 is transmitted to the front rail 150 through the front strut 30, So that safety can be improved by improving collision energy flow.

The cowl rear panel 130 is vertically connected to the rear side of the cowl center panel 110 and has both ends connected to the A-pillar portion provided behind the front strut portion 30, do.

Here, a rear rainfall 160 for increasing the rigidity of the cowl rear panel 130 is provided on one side of the cowl rear panel 130, preferably an outside side (a surface facing the rear side of the vehicle) (160) forms a closed end face of a 'K' shape through coupling with the cowl rear panel (130).

That is, a rear end face 160 having a 'C' -shaped cross-sectional shape is coupled to the outer surface of the cowl rear panel 130 to form a closed end face of the 'ㅁ' shape, Thereby increasing the rear rigidity of the cowl portion and improving the collision performance.

In addition, both ends of the rear rail 160 are coupled to the A-pillar portion, and impact force transmitted from the front side member 10 is transmitted to the rear rail 160 through the A-pillar portion, Improvement can improve safety.

The supporting member 140 is connected to the upper end of the cowl rear panel 130 to support the window portion.

The cowling structure 100 having such a configuration combines the front rainfall 150 and the rear rainfall 160 to the cowl front panel 120 and the cowl rear panel 130 to form a ' The collision performance can be effectively improved. In other words, the impact force transmitted to the front face at the time of frontal collision can be increased primarily by the front and rear of the cowl structure 100, which is a box structure, and the front side member 10 The collision energy transmitted to the front rainfall 150 and the rear rainfall 160 can be increased and the collision performance can be increased in a second order as the impact energy is separated.

The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
