Description

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to Korean Patent Application Number 10-2008-0033845, filed on Apr. 11, 2008, 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 post-mounting structure of a cowl complete panel with improved design freedom of a front pillar part, and more particularly, to a post-mounting structure of a cowl complete panel, in which a front pillar part can be freely designed without changing the layout of the existing factory equipment, and thus design freedom of the front pillar part can be enhanced.
2. Description of Prior Art
In general, a car body of a vehicle takes a box shape constructed from a proper combination of various panels and a frame, and the car body produced from such a combination in which the frame and the body are integrally formed is referred to as a monocoque structure.
An assembling sequence of such a monocoque structure is determined according to the layout of production lines of a vehicle manufacturing company. A front part, a center part, a rear part, and a dashboard part are first assembled, and then a side structure part is assembled. Finally, a cowl part is mounted.
The cowl part restrains vibration occurring during the drive of a vehicle, and particularly, twist of a car body occurring at a sharp turn thereof, absorbs impact energy occurring at a collision of the vehicle, and prevents various components in an engine compartment from entering into a compartment of the vehicle due to the impact energy.
FIG. 1 is a plan view illustrating a conventional mounting structure of a cowl complete, and FIG. 2 is a perspective view illustrating the mounting structure of FIG. 1.
As illustrated in FIGS. 1 and 2, according to the conventional mounting structure of the cowl complete, a front parting line A of a side outer panel 12 constituting a front pillar part is formed normal with respect to the front pillar part. That is, the front parting line A is formed along a cowl top panel 22.
Accordingly, in the case of post-mounting the cowl complete 20, no interference occurs between the cowl complete 20 and the side outer panel 12, and thus there is no problem in loading the cowl complete from the upper direction. This structure has been currently used in most vehicle manufacturing equipment, and it is general that factory layout is provided to suit the structure.
However, the conventional mounting structure as described above has the problem that it severely limits the design freedom of the front pillar part. That is, in this case, interference occurs from downward direction between the cowl complete and the side outer panel due to the limited space in front of the cowl top panel 22, and thus it is impossible to post-mount the cowl complete.
Accordingly, in the case of designing the side outer panel as described above, it is required to pre-mount the cowl complete. In order to pre-mount the cowl complete, however, the whole layout of the factory equipment should be changed at a great cost, and thus it is actually impossible to change the design of the side outer panel as described above.
In conclusion, the existing post-mounting structure of the cowl complete has the problem that it limits the design of the side outer panel constituting the front pillar part within specified range.
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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims. Also, well-known functions or constructions or repeated description thereof may be omitted.
FIG. 3 is a side view illustrating a side outer panel constituting a front pillar part according to various exemplary embodiments of the present invention. FIG. 4 is a plan view illustrating a cowl complete adopting a side outer panel of FIG. 3, and FIG. 5 is a perspective view illustrating the cowl complete of FIG. 4.
As illustrated in FIGS. 3 to 5, a post-mounting structure of a cowl complete panel according to various exemplary embodiments of the present invention includes a front pillar part including a side outer panel 112, and a cowl complete 120 including a cowl top panel 122 and a cowl side inner member 124.
Here, a front parting line E of the side outer panel 112 may be formed to project ahead of a connection portion of the side outer panel 112 and the cowl top panel 122. For example, the parting line B of the side outer panel 112 may be formed to achieve a parting line “E” as seen from the side as illustrated in FIGS. 3 and 4.
On the other hand, as illustrated in FIG. 4, the side shape of the outside of the cowl top panel 122 may be formed to correspond to the side shape of a compartment side of the side outer panel 112 so that the side shape of the outside of the cowl top panel 122 does not interfere with the side shape of the compartment side of the side outer panel 112 in upward and downward directions within a range where post-mounting of the cowl complete 120 is not obstructed. Specifically, the parting line C of the outside of the cowl top panel 122 may be formed to correspond to the side shape of the compartment side of the side outer panel 112.
As the cowl top panel 122 is constructed as described above, the shape of the outside of the cowl complete 120 does not interfere with the shape of the compartment side of the front pillar part even if the cowl complete 120 is loaded after the front pillar part and so on is mounted, and thus the post-mounting of the cowl complete 120 is not obstructed by the shape of the compartment side of the front pillar part.
In addition, as illustrated in FIG. 5, the front pillar part may further include a side outer reinforcement 114 provided inside the side outer panel 112, and the cowl complete 120 may further include a cowl inner lower panel 126 provided on the lower side of the cowl top panel 122 to match the side outer reinforcement 114.
Here, the side outer reinforcement 114 may be provided with a first combination surface portion extending to the compartment side, and the cowl inner lower panel 126 may be provided with a second combination surface portion extending to the outside to match the first combination surface portion. Accordingly, the side outer reinforcement 114 and the cowl inner lower panel 126 can be connected together through the combination surface portion (i.e. matching surface portion) 116.
In various embodiments of the present invention, it is preferable that the matching surface portion 116 is positioned on the compartment side of the vehicle, which is more inside the front parting line E of the side outer panel 112 or the inner parting line C of the outside of the cowl top panel 122. Through the matching surface portion 116, the side outer reinforcement 114 and the cowl inner lower panel 126 are firmly connected together, and the post-mounting of the cowl complete 120 is not obstructed by the matching surface portion 116.
On the other hand, as illustrated in FIG. 4, a forward parting line D disposed in front portion of the cowl side inner member 124 is formed ahead of the parting line E disposed in the front side of the side outer panel 112, so that the rear portion of the cowl side inner member 124 does not interfere with the front shape of the side outer panel 112 in upward and downward directions within the range where the post-mounting of the cowl complete 120 is not obstructed. As the parting lines are formed as described above, a specified space may be formed between the forward parting line D disposed in front portion of the cowl side inner member 124 and the parting line E of the front side of the side outer panel 112.
As the forward parting line D is disposed in front portion of the cowl side inner member 124 as described above, no interference occurs between the cowl side inner member 124 and the front shape of the front pillar part even if the cowl complete 120 is loaded after the front pillar part and so on is mounted, and thus the post-mounting of the cowl complete 120 is not obstructed by the front shape of the front pillar part.
However, due to the specified space formed between the forward parting line D disposed at the front portion of the cowl side inner member 124 and the parting line E of the front side of the side outer panel 112, wind noise and so on may occur to deteriorate the NVH (Noise, Vibration, and Harshness) performance of the vehicle. On the other hand, FIG. 6 is a perspective view illustrating a cowl side upper outer bracket provided in a specified space formed between the parting line of the front side of the cowl side inner member and the parting line of the front side of the side outer panel according to various embodiments of the present invention, and FIG. 7 is a plan view illustrating a structure on which a cowl side upper outer bracket 128 is mounted according to various embodiments of the present invention.
In order to prevent the performance deterioration as described above, as illustrated in FIGS. 6 and 7, the post-mounting structure of the cowl complete panel according to various embodiments of the present invention may further include the cowl side upper outer bracket 128 formed to correspond to a space formed between the side outer panel 1 12 and the cowl side inner member 124 and provided in the space. This cowl side upper outer bracket 128 can be pre-assembled before the cowl complete 120 is loaded.
Since the post-mounting structure of the cowl complete panel according to various embodiments of the present invention further includes the cowl side upper outer bracket 128 as described above, the NVH performance of the vehicle can be improved, and the combination relation between the panels can be strengthened.
The post-mounting structure of the cowl complete panel according to various embodiments of the present invention makes it possible to post-mount the cowl complete even without changing the layout of the existing factory equipment irrespective of the parting structure of the front pillar part.
By contrast, according to the conventional cowl complete structure as illustrated in FIG. 1, in the case where the parting line of the side outer panel 12 constituting the front pillar part is formed along the connection portion of the side outer panel 12 and the cowl top panel 22, interference occurs from downward directions between the cowl complete 20 and the side outer panel 12, and thus it is impossible to post-mount the cowl complete 20. Accordingly, the conventional post-mounting structure of the cowl complete has the problem that it limits the design of the side outer panel constituting the front pillar part within specified range.
However, according to the post-mounting structure of the cowl complete panel according to the present invention as illustrated in FIGS. 8 and 9, since the side shape of the outside of the cowl top panel 122 and the parting line of the rear side of the cowl side inner member 124 are formed so that they do not interfere with components of the front pillar part in upward and downward directions, the cowl complete 120 can be post-mounted irrespective of the parting lines of the front pillar part. Accordingly, the design freedom of the front pillar part can be heightened.
Also, since the post-mounting structure of the cowl complete panel according to the present invention further includes the cowl side upper outer bracket 128, the NVH performance of the vehicle can be improved, and the combination relation between the panels can be strengthened.
