Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a drip channel mounted along the side surface of a vehicle body of an automobile, and more particularly to a split drip channel in which the drip channel is divided into a front portion and a rear portion. Regarding the binding structure in the channel.

[Conventional technology]

Generally, in an automobile with a drip channel, the body mounting surface of the drip channel is configured to be reversed from downward to upward from the vicinity of the front pillar to the side roof rail. This is because when the roof is on, the body panel mounting surface of the drip channel can be hidden by this roof panel, so that the body panel mounting surface is formed upward. On the other hand, since there is no roof panel in front of the front pillar, the body panel mounting surface of the drip channel cannot be hidden by the roof panel. Therefore, at this location, the body mounting surface of the drip channel is formed downward and is welded to the lower surface of the side roof rail outer.

In this way, since the vehicle body side mounting surface of the drip channel changes before and after the front pillar, it is difficult to form the front part and the rear part integrally, and therefore the front drip channel and the rear drip channel are difficult to manufacture. There is no choice but to divide and form into channels.

This is shown in FIG. 5 (perspective view of automobile with drip channel), FIG. 6 (enlarged view of IV portion in FIG. 5), FIG. 7 (cross-sectional view taken along the line VII-VII in FIG. 6), and FIG. VIII-VIII in Figure 6
A cross-sectional view taken along the arrow), FIG. 9 (exploded perspective view), and FIG. 10 (cross-sectional view taken along the line XX in FIG. 6) explain the drip channel 3 along the side surface of the vehicle body 1. Has been done.

The drip channel 3 extends from the vicinity of the front pillar 2 to the side roof rail, and is divided into a front drip channel 4 having a downward body mounting surface 4a and a rear drip channel 5 having an upward body mounting surface 5a.

That is, the body mounting surface 5a of the rear drip channel 5
Is bent upward to the side of the side roof rail outer 8
It is welded to 8a and is hidden by the roof panel 6 as shown in FIG.

On the other hand, the body mounting surface 4a of the front drip channel 4 is bent slightly downward and is welded to the lower surface 8b of the side roof rail outer 8 as shown in FIG.

Reference numeral 7 in the figure indicates both drip channels 4 and 5.
Reinforcement plate provided at the joint part of, 9 is a side roof rail inner, 10 is a sealer, and reference numeral 4
Reference numerals b and 5b respectively denote a front curl portion and a rear curl portion formed at the outer end portions of the front drip channel 4 and the rear drip channel 5, respectively.

[Problems to be solved by the device]

By the way, in the conventional vehicle drip channel coupling structure as described above, the front drip channel and the rear drip channel, which are separate from the front drip channel, are abutted in the vicinity of the front pillar, so that the rigidity of the drip channel is increased. Is insufficient to cause seal cracking. Conventionally, this inconvenience has been dealt with by a configuration in which a reinforcing plate 7 is added to the butted portion.

As described above, in the conventional structure, since the reinforcing plate is required as a separate component, the weight of the vehicle body is increased and the number of assembling steps and the number of components are also increased, which causes a problem of cost increase.

The present invention is intended to solve such a problem, in which the rear end portion of the rear drip channel is formed with an upper claw portion which can superimpose the rear end portion of the front drip channel on the lower side. By superposing the front end of the rear drip channel and the rear end of the front drip channel at the upper cut portion, the rigidity of the joint portion of both drip channels is increased, and the durability against deformation of the body itself and An object of the present invention is to provide an automobile drip channel coupling structure that improves the strength of the drip channel against the load when the roof carrier is mounted.

[Means for solving the problem]

In order to achieve the above-mentioned object, the connection structure of an automobile drip channel of the present invention comprises a rear drip channel formed with an upward body mounting surface and a rear curl portion, which are connected to an automobile side roof rail, and a rear drip channel. A front drip channel having a rear end portion connected to the front end portion of the side drip channel and having a downward body mounting surface connected to the side roof rail and a front curl portion connected to the rear curl portion; In the above, the upper claw portion is formed at the front end portion of the rear drip channel, and is inserted into the rear end portion of the front drip channel below the upper claw portion to form the upper claw portion. A polymerized portion to be polymerized is formed, and the front end portion of the rear curl portion of the rear drip channel is notched by a length substantially corresponding to the polymerized portion. When the front end surface of the rear curl portion is abutted against the rear end surface of the front curl portion, the overlapping portion formed in the front drip channel and the upper barbed portion formed in the rear drip channel. It is characterized in that and can be polymerized.

[Action]

In the above-described vehicle drip channel coupling structure of the present invention, the front end surface of the rear curl portion is butted against the rear end surface of the front curl portion, and the overlapping portion formed in the front drip channel is formed in the rear drip channel. Since it is polymerized on the lower side of the upper claw portion, the rigidity of the joint portion of the both drip channels can be increased without using a reinforcing plate at this joint portion.

Also, since both drip channels form a continuous drip channel, rainwater in the drip channel flows down along the front pillar via the front drip channel, and rainwater enters from the joint part of both drip channels. You can avoid that.

〔Example〕

Hereinafter, a connection structure of an automobile drip channel according to an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 to 4, the same reference numerals as those in FIGS. 5 to 10 indicate almost the same members.

The drip channel of this embodiment is also composed of a front drip channel 4 and a rear drip channel 5, and the front drip channel 4 has a downward mounting surface 4a to the vehicle body, and the front drip in the case of the above-mentioned conventional example. It has almost the same structure as the channel.

On the other hand, the rear drip channel 5 is the same as the rear drip channel in the case of the above-mentioned conventional example in that the rear drip channel 5 has an upward mounting surface 5a on the vehicle body.
An upper claw portion (step portion) 5d is formed on the bottom surface 4C of the front drip channel 4 from the lower side. Code 5e
Indicates an inclined portion connecting the upper claw portion 5d and the bottom surface 4c, and the upper claw portion 5d is the bottom surface 4c of the front drip channel 4.
Is offset upward from the bottom surface 5c by a dimension corresponding to the thickness of the.

Also, the rear curl portion 5b of the rear drip channel 5
Has a configuration in which the length corresponding to the overlapping dimension l of the front drip channel 4 is eliminated.

With the above-described configuration, the front drip channel 4 and the rear drip channel 5 are joined so that the front end surface of the rear curl portion is abutted against the rear end surface of the front curl portion, and the overlapping portion formed in the front drip channel is rearward. Since it is carried out by superimposing it on the lower side of the upper claw formed on the side drip channel, the rigidity of the joint part of both drip channels can be increased, and at the same time, the continuous drip channel by both drip channels can be increased. , Can be formed along the side surface of the roof panel 6 of the automobile.

Therefore, unlike the case of the above-mentioned conventional example, it is not necessary to separately weld the reinforcing plate to the joint portion of both drip channels, and as a result, it is possible to increase the weight of the vehicle body and reduce the number of assembly steps and the number of parts, Further, rainwater in the drip channel can be smoothly flowed down along the front pillar via the front drip channel, so that rainwater can be prevented from entering the joint portion of both drip channels.
