Description

[Detailed Description of the Invention] The present invention relates to an automobile body, particularly a cowl structure.

As a conventional cowl structure, for example, as shown in FIGS. 1 to 4, there is a dash upper panel 2 that forms the upper part of a dash panel 1 that partitions an engine room E and a vehicle interior C.
A cowl top panel 4 is joined to this dash upper panel 2 at both front and rear ends to form an air box B having a box-like vertical cross section, and a cowl side panel 6 closes both ends of the air box B. Panel 2
An air inlet 2a for an air conditioner or a ventilation device is provided in the housing, and a draining cover 10 is attached to cover the upper surface of the air inlet 2a.

(See Fig. 3) Furthermore, a pedal bracket 12 is attached to the driver's seat side portion of the vehicle interior C of the dash upper panel 2 via a mounting bracket 14. A reinforcement 16 is welded to the box B side portion.

(See Figure 2) A wiper pivot bracket 20 is welded to the upper joining flange portion 18 of the dash upper panel 2 and cowl top panel 4, and the wiper linkage 22
is installed.

(See Fig. 4) An outside air inlet 24 is provided in the cowl top panel 4 as shown in Fig. 1.
The cowl grill 2 has a plurality of slits 26a on the top.
6 is installed.

The cowl side panel 6 has a front end connected to the hood ledge panel 28 and a rear end connected to the front pillar 32 via a connector panel 30, and has three box-shaped members, namely, the dash upper panel 2 and the cowl top panel. 4
The combination of the hood ledge panel 28 and its reinforcement 34, and the front pillar 32 (the outer panel 32a and the inner panel 32b form a box shape in horizontal section) are combined to form the main pillar girder of the vehicle body. forming a structure.

However, in such a cowl structure, since the drain cover 10 is attached to the dash upper panel 2 as a separate member by welding, there is a problem that the cowl structure is complicated and the workability of attaching various parts is poor.

In addition, especially since the drain cover is welded separately, rainwater can enter the joints of the drain cover, causing rust over long periods of use, and as this rust progresses, the drain cover may fall off, causing the drain cover to fall off. There is also a possibility that the outside air introduction function may not be effective.

Therefore, in order to prevent this rusting, a sealant is actually loaded at the joint end of the dash upper panel and the drain cover to prevent water from entering, which creates a new problem in that the work of applying the sealant is also difficult. is also occurring.

In view of the conventional situation, the present invention aims to provide a cowl structure that is simple and has excellent mounting rigidity when attaching various parts.The present invention is based on the embodiments shown in the drawings below. The details are as follows.

In FIGS. 5 to 8, a cowl front panel 40 forming an air box B is joined to the dash upper panel 2 at the joining end thereof to the dash panel 1.

On the other hand, an upper end part 42a is joined to the rear upper end flange part of the dash upper panel 2, and a lower end part 42b is joined to the middle part 2b of the dash upper panel 2, dividing the rear part of the air box B into a vertical cross-sectional box. A cowl rear panel 42 defining a shaped space a is provided.

(See Fig. 6) A part of this cowl rear panel 42 is made to protrude toward the cowl front panel 40 side (3 in the figure).
Location) An opening 50,
52 and 54 are formed, and the air box B and the box-shaped space a are communicated with each other.

To explain each of the overhanging parts 44, 46, and 48 in more detail, the overhanging part 44 is curved and bulged out so as to cover the upper part of the air inlet 2a formed in the dash upper panel 2, as shown in FIG. It forms part of the cover.

Note that the air inlet 2a is located behind the opening 50, that is, in the vehicle compartment C.
Of course, it is located on the side.

Next, as shown in FIG.
, and insert the wiper linkage 22 into its mounting hole 56.
58 peripheral edge.

The mounting bracket 14 of the pedal bracket 12 is bolted to the driver's seat side in a region where the projecting portions 44, 46, 48 are not formed, that is, a region having the cross-sectional structure shown in FIG.

Further, since the upper surface of the air box B is open to the atmosphere, this upper surface is covered with a cowl grille 26 having a large number of slits 26a.

With this configuration, the panel constituting the cowl is divided into two parts, the front panel 40 and the rear panel 42, and the cowl rear panel 42 and the dash upper panel 2 form a box-shaped vertical section B□, so that the mounting part of the pedal bracket 12 is Sufficient support rigidity can be ensured without having to take the trouble of attaching a reinforcement to the part where the bracket 14 is attached to increase the support rigidity as in the conventional case.

In addition, the air intake port 2a opened on the dash upper panel 2
Since the upper part of the drainer is covered by the curved and bulging projecting part 44, there is no need to take the trouble of attaching a draining cover to provide a draining function as in the conventional case.

Further, since the wiper linkage mounting holes 56.58 are formed in the projecting portion 46.48, there is no need to take the trouble of attaching a wiper bracket as in the conventional case.

In the above embodiment, both side walls of the air box B are formed by the cowl side panels 6, but since the air box B has an open cross-section structure, the dash upper panel 2 is extended in the vehicle width direction 2C. The extension portion 2c can be directly joined to the front pillar 32, eliminating the need for a conventional connector and increasing the rigidity of the coupling between the cowl structure and the front pillar 32.

The naori side panel 6 is joined to the dash upper panel 2 so as to be placed on top of the dash upper panel 2.

As described above, in the present invention, the panel constituting the cowl is divided into two parts, the front panel and the rear panel, and the cowl rear panel and the dash upper panel 2 form a vertical cross-sectional box shape to ensure the same rigidity as the conventional one. The cowl structure has a clean and simple structure, and a part of the cowl rear panel is extended to form an opening for introducing outside air, and the upper part of the air inlet on the dash upper panel is covered to form a part of the drain cover. Because of this, there is no need to install a separate draining cover like in the past, and it ensures that rainwater does not enter the room.Furthermore, there is no need to worry about rusting even after long-term use, and there is no need to apply a sealant. This has the effect of making it unnecessary.

Furthermore, it is extremely effective in the production of automobiles, as it is easy to attach various attachment parts and eliminates problems caused by forgetting to attach them.
