Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a structure of an automobile deck drainage part, and more particularly to a connection structure of the deck drainage part.

[Prior Art] A front deck portion of a passenger car is configured as a joint portion between an engine room and a front pillar, and a cowl top, a pillar, and a frame are configured as shown in detail in a perspective view of FIG. It has a structure in which the cowl top inner 1, the pillar outer 2, and the upper frame 3, which are respective members, are joined to each other.

That is, as shown in FIG. 6 (a cross-sectional view taken along the line VI-VI in FIG. 5), the outer portion in the general cross section of this portion is a flange portion 31 that extends horizontally to the outside of the upper frame 3 and a cowl top. An outer edge portion 11 of the inner 1 and a flange 21 that extends horizontally above the pillar outer 2 are spot-welded at a number of striking points S and are connected to each other.

By the way, this front deck part is usually provided with a drainage part so that rainwater and the like flowing in through the opening of the cowl top can be moved downward as shown by an arrow in FIG. 7 (VII-VII arrow sectional view of FIG. 5). A drain port 4 that is dropped and discharged to the outside of the vehicle is formed between the upper frame 3 and the pillar outer 2.

Conventionally, in such a drainage portion, unlike the other general cross section, the outer end flange portion 31 of the upper frame 3 is not fixed to another member.

[Problems to be solved by the device]

By the way, in the conventional vehicle deck drainage structure as described above, the joint portion by the spot welding is on the extension of the strut as a component of the front suspension,
The force in the peeling direction due to the push-up force acts strongly.

As is known, the spot welding point has a weak joining force against the force in the peeling direction, so that the structure in which the horizontal planes are welded to each other as described above is not always sufficient in terms of strength,
In particular, in the case of the deck drainage port having no welding point, the need to improve the durability against such thrust force remains a problem.

Further, in the structure having an opening opened to the side like the drainage port 4 in the conventional drainage part, rainwater tends to be scattered laterally, and the side turn installed outside the drainage port 4 is strong. There is also a problem that the connector portion 5 of the lamp is contaminated.

The present invention is intended to solve these problems, and improves the drainage performance as well as improving the coupling strength of the deck portion, particularly the drainage portion, against the thrust force of the suspension strut. It is an object of the present invention to provide an automobile deck drainage structure.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the vehicle deck drain structure of the present invention is provided with a drain port formed at a connecting portion between a pillar outer of a front pillar and an upper frame in a vehicle deck section, and the drain port is located laterally. A cover portion that can cover the above and guide the drainage flow downward is formed as a downward extension of the upper frame, and the pillar outer and the upper frame are provided on the front side and the rear side of the cover portion, respectively. It is characterized in that the connection with and was performed by spot welding in the vehicle width direction.

[Action]

In the above-described automobile deck drain structure of the present invention, the cover portion formed as the lower extension of the upper frame so as to cover the drain outlet of the deck from the side flows from the opening of the cowl top and follows the cowl top. It acts as a duct that guides and discharges rainwater flowing laterally downwards, and the connection between the pillar outer and upper frames on the front and rear sides of this cover by spot welding is performed. Acts to strengthen the bond.

〔Example〕

Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view showing an automobile deck drainage structure as one embodiment of the present invention, and FIG. 2 is an overall perspective view of a vehicle body showing its disposition position. 3 is a sectional view taken along the line III-III in FIG. 1, and FIG. 4 is a sectional view taken along the line IV-IV in FIG.

As shown in FIG. 2, an automobile deck drainage structure as one embodiment of the present invention is provided at a joint portion C between an engine room and a front pillar in a passenger car, and as shown in FIG. The cover part that is applied to the drain part formed at the joint between the pillar outer 2 and the upper frame 3 of the front pillar in the front deck part of the vehicle and that can cover the drain port from the side and guide the flow of drain downward.
32 is formed as a downward extension of the upper frame 3.

The pillar outer 2 and the upper frame 3 are respectively connected to the front side 33 and the rear side 34 of the cover portion 32 by spot welding at a number of hit points S in the vehicle width direction.

More specifically, as shown in FIGS. 1 and 3, the outer portion in the general cross-section of this portion is the front side 33 of the cover portion 32 formed as the downward extension of the upper frame 3.
And a portion extending above the pillar outer 2 are spot-welded at a large number of hit points S. Such a bond structure is
The same applies to the rear side 34 of the cover portion 32.

According to such a joint structure, the spot welding direction is necessarily oriented in the vehicle width direction, and the force due to the push-up force applied to the strut of the front suspension acts as a force in the shearing direction on the welded portion. .

On the other hand, as shown in FIG. 4, the outer portion of the drainage port has a sufficient area due to the extension of the upper frame 3 downward, and the rigidity is improved by the sheet metal formation of the cover portion.
Sufficient rigidity can be maintained even though there is no connection point to the pillar outer 2.

By the way, the drainage part as described above is usually close to the connector on the back side of the side turn lamp installed in the fender of the automobile, and the drainage port opens toward the side as shown in the conventional structure of FIG. In this case, the drained rainwater directly hits this connector. However, in the structure of this embodiment of the present invention, the cover portion 32 of the upper frame 3 causes the rainwater or the like to be indicated by an arrow in FIG. The connector is directed downwards and then discharged, so that the connector is not contaminated.

In addition, since the duct is formed in the drainage portion by forming the extended cover portion 32 in this manner, a path that hinders the odor and noise that enter the vehicle interior from the drainage port 6 is formed and the deodorization is performed. , The sound insulation effect is also improved.

Although the present invention has been described above in detail based on an embodiment in which it is applied to a front deck portion of a passenger car, the present invention is not limited to the above-mentioned embodiment, and can be applied to other parts of an automobile. Therefore, the invention can be implemented with various modifications within the scope of the matters described in the scope of claims for utility model registration.

[Effect of device]

As described above in detail, according to the vehicle deck drainage structure of the present invention, the following effects and advantages are obtained.

(1) Since the upper frame is extended downward and the cover portion is formed, the rigidity of the upper frame itself is improved.

(2) Because the structure is such that the downwardly extended portion of the upper frame and the pillar outer are spot welded to each other,
The welding surface can be widely taken, and the strength can be improved by increasing the number of welding spots.

(3) Since spot welding is performed in the vehicle width direction on the joining surface between the upper frame and the pillar outer, the force applied to the joining portion becomes a shearing force, and the durability of the joining portion against stress is improved.

(4) Since the opening of the drainage port is directed downward and the splashing of running water to the parts installed on the outside thereof is prevented, it is possible to eliminate the adverse effect on it.

(5) Since a relatively long duct is formed between the cover portion of the upper frame and the pillar outer, invasion of odor and noise from the outside is prevented, and deodorization and sound insulation effects are obtained.
