JP2017-88090A

In a vehicle structure in which a loading platform is provided at the rear of the cabin, rainwater may flow forcefully from the rear end of the drip rail toward the loading platform. Depending on the force of the rainwater, there is a risk that cargo placed on the loading platform may be damaged, especially cargo that requires careful handling such as plants.

One of the objects of the present invention is to provide a vehicle structure that can suppress the force of water flowing out from the rear end of a drip rail.

A vehicle structure according to one aspect of the present invention includes:
The cabin and
a loading platform provided on the rear side of the vehicle compartment;
A drip rail provided on a side edge of a roof panel constituting the vehicle compartment;
a garnish arranged to cover the rear end of the drip rail,
The garnish includes an inner surface located on an extension of the drip rail,
The inner surface extends in a direction intersecting an extending direction of the drip rail.

Water accumulated on the drip rail flows out from the rear end of the drip rail toward the rear of the vehicle. In the vehicle structure of the present invention, the flow of water flowing out from the rear end of the drip rail is directed to the side of the vehicle along the inner surface of the garnish disposed at the rear end of the drip rail. By diverting the flow of water to the side, the force of the water decreases. That is, with the vehicle structure of the present invention, the force of water flowing out from the rear end of the drip rail can be suppressed. By suppressing the force of the water, it is possible to prevent the forceful water from splashing onto the cargo placed on the loading platform.

The drip rail 4 is a gutter-like member. The front end of the drip rail 4 is open forward. A rear end portion 40 of the drip rail 4 is open rearward. Water accumulated on the drip rail 4 flows out from the front end or the rear end 40 of the drip rail 4. For example, when the vehicle is running in the rain, water accumulated on the drip rail 4 flows out from the rear end portion 40 toward the loading platform 3 side.

<Roof garnish>
The roof garnish 6 is arranged to cover the rear end portion 40 of the drip rail 4, as shown in FIG. The roof garnish 6 has a function of suppressing the force of water flowing out from the rear end portion 40 of the drip rail 4. The roof garnish 6 is attached to the left and right sides of the vehicle. The left roof garnish 6 and the right roof garnish 6 are symmetrical. In this example, the roof garnish 6 on the right side will be explained.

The roof garnish 6 covers the rear end portion 40 of the drip rail 4 and also covers the curved portion 213 (FIG. 3) of the roof panel 21. The roof garnish 6 covers the area from the top surface to the side surface of the roof panel 21 and the rear end surface of the roof panel 21 so as to cover the curved portion 213 of the roof panel 21 . The roof garnish 6 of this example extends generally rearward from the front end, then curves from the inside to the outside and extends outward, and then curves from the top to the bottom and extends downward to reach the rear end. The roof garnish 6 of this example has an arcuate shape that curves from the inside to the outside as it goes from the front to the rear when viewed from above. Moreover, the roof garnish 6 of this example is configured in an arcuate shape that is curved from the front to the rear as it goes from the top to the bottom when viewed from the outside. Moreover, the roof garnish 6 of this example is configured in an arcuate shape that curves from the top to the bottom as it goes from the inside to the outside when viewed from the rear.

The roof garnish 6 of this example covers the portions of the roof panel 21 and the corner panels 5 that are so curved that they cannot be hemmed and have sharp edges. The roof garnish 6 is provided with a through hole (not shown) at a location corresponding to the through hole provided in the corner panel 5 described above. A fixing portion 7 (FIG. 2) is inserted into the through hole of the corner panel 5 and the through hole of the roof garnish 6. The roof garnish 6 is fixed to the corner panel 5 by this fixing part 7. The roof garnish 6 is fixed to the roof panel 21 via the corner panel 5. The fixing part 7 is, for example, a fastening member such as a screw.

The roof garnish 6 includes a side portion 61, an upper portion 62, and a rear portion 63, as shown in FIG. The side portion 61 is a portion that generally covers the sides of the drip rail 4. The upper part 62 is a part that generally covers the upper part of the drip rail 4. The rear portion 63 is a portion that generally covers the rear of the drip rail 4.

As shown in FIG. 3, the roof garnish 6 includes a guide surface 630s that changes the flow direction of water flowing out from the rear end 40 (FIG. 2) of the drip rail 4. The guide surface 630s is the inner surface of the roof garnish 6 located on the extension line of the drip rail 4. The guide surface 630s is part of the inner surface 630 of the rear portion 63. In FIG. 3, the region of the guide surface 630s is schematically shown surrounded by a two-dot chain line. The inner surface 630 including the guide surface 630s extends in a direction intersecting the extending direction of the drip rail 4 (FIG. 2). The extension line of the drip rail 4 is an extension line of the cross section of the drip rail 4. The cross section of the drip rail 4 is a cross section cut in a direction perpendicular to the extending direction of the drip rail 4. The guide surface 630s is arranged so as to overlap at least a lower region of the cross section of the drip rail 4. This is because rainwater flows along the bottom surface of the drip rail 4. The guide surface 630s is preferably arranged so as to overlap the entire area of the cross section of the drip rail 4.

As shown in FIG. 2, the side portion 61 in this example extends further toward the rear of the vehicle and also covers the side of the corner panel 5. A first shelf portion 651 is provided at the lower edge of the side portion 61 . The first shelf portion 651 extends from the lower edge of the side portion 61 toward the inside of the vehicle. The tip of the first shelf 651 in the extending direction is close to or in contact with the side surface of the corner panel 5. The first shelf portion 651 is provided over the entire length along the lower edge of the side portion 61. The first shelf 651 is arranged to cover the lower part of the drip rail 4. The rear end portion 40 of the drip rail 4 is surrounded by side portions 61, an upper portion 62, and a first shelf portion 651. In this example, a rib 671 that protrudes upward is provided at the end of the first shelf 651 on the drip rail 4 side. In this example, the rear end portion 40 of the drip rail 4 is arranged on the rib 671.

The upper part 62 in this example further extends above the vehicle, and also covers the sides and above of the roof panel 21 and the sides and above of the corner panel 5. In this example, a space is defined inside the roof garnish 6 by the side portion 61, the upper portion 62, the first shelf portion 651, and the side surface of the corner panel 5. This space functions as a first flow path 91 that guides water flowing out from the rear end portion 40 of the drip rail 4 to the rear along the first shelf portion 651.

The rear portion 63 in this example further extends both inside and above the vehicle, and also covers the rear of the corner panel 5. A second shelf 652 is provided at the lower edge of the rear portion 63. The second shelf portion 652 extends from the lower edge of the rear portion 63 toward the front of the vehicle. The second shelf 652 is provided over the entire length along the lower edge of the rear portion 63. The second shelf section 652 is provided continuously from the first shelf section 651. The extending direction of the first shelf section 651 and the extending direction of the second shelf section 652 intersect. In this example, the space is constituted by the rear part 63, the upper part 62, and the second shelf part 652. This space functions as a second flow path 92 that guides the water whose flow direction has been changed by the guide surface 630s (FIG. 3) to the inside in the vehicle width direction along the second shelf portion 652. The first flow path 91 and the second flow path 92 are a series of flow paths. The end of the second flow path 92 opens to the inside of the vehicle. A space is formed beyond the second shelf portion 652 in the extending direction in this example. Therefore, the second flow path 92 opens inside the roof garnish 6.

<Pillar Garnish>
The pillar garnish 80 covers the rear pillars 8 provided at both left and right ends of the rear of the vehicle interior 2, as shown in FIG. The pillar garnish 80 also covers the lower area of the corner panel 5, as shown in FIG. Spaces are defined between the corner panel 5 and the pillar garnish 80 and between the rear pillar 8 and the pillar garnish 80. The upper end of this space is located below the tip of the second shelf 652 in the extending direction. That is, the upper end of this space communicates with the space beyond the second shelf section 652 in the extending direction. This space functions as a third flow path 93 that guides the water flowing out from the second flow path 92 downward.

<Action of the embodiment>
In the vehicle structure 1 of the embodiment, water flowing out from the rear end portion 40 of the drip rail 4 flows toward the first flow path 91 on the first shelf portion 651 inside the roof garnish 6, as shown in FIG. In this example, since the rear end portion 40 of the drip rail 4 is disposed on the rib 671, a step is provided between the rear end portion 40 of the drip rail 4 and the first shelf portion 651. This level difference reduces the flow rate of water when it flows into the first flow path 91 from the rear end portion 40 of the drip rail 4.

The water that has flowed into the first channel 91 flows backward on the first shelf 651. A guide surface 630s (FIG. 3) is located at the tip of the first shelf 651. Therefore, the water flowing through the first channel 91 hits the guide surface 630s. This guide surface 630s changes the direction of water flow. Moreover, the flow velocity of the water decreases by hitting the guide surface 630s.

The water whose flow direction has changed on the guide surface 630s heads toward the second channel 92 on the second shelf 652. In this example, the water that has flowed into the second flow path 92 flows inward in the vehicle width direction.

The flow rate of water flowing into the second flow path 92 is considerably smaller than the flow rate of water flowing out from the rear end portion 40 of the drip rail 4. The inner side of the roof garnish 6 in the second flow path 92 is open, and the opening of the pillar garnish 80 is located near the opening. Therefore, at least a portion of the water on the second shelf 652 whose momentum has become smaller can flow into the third flow path 93, as shown in FIG. 3, for example due to vibration or the like. The water that has flowed into the third flow path 93 flows downward within the pillar garnish 80 and is discharged onto the loading platform 3. Another part of the water on the second shelf portion 652 whose momentum has become smaller may be discharged toward the loading platform 3 side from the opening on the inside of the vehicle in the second flow path 92 toward the inside of the vehicle.

<Effects of embodiment>
In the vehicle structure 1 of the embodiment, the roof garnish 6 can suppress the force of water flowing out from the rear end portion 40 of the drip rail 4, and can suppress the forceful water from being discharged to the loading platform 3 side. It is possible to prevent the water from splashing on the cargo placed on the loading platform 3, especially the cargo that requires careful handling such as plants, and to prevent damage to the cargo.

By arranging the roof garnish 6 on the curved portion 213 of the roof panel 21, it is possible to prevent damage to the cargo at the curved portion 213 when the cargo is placed on the loading platform 3.

By arranging the roof garnish 6 at the curved portion 213 of the roof panel 21, it is possible to hide the portions of the roof panel 21 and the corner panels 5 that are curved so much that they cannot be hemmed and have an edge. . Therefore, the edges of the portions of the roof panel 21 and the corner panels 5 covered by the roof garnish 6 may be maintained in an upright state. Therefore, it is possible to omit the work of applying a grinder polishing treatment to the sharp edges. In addition, it is also possible to hide spot dents and the like at the joints of sheet metals such as the roof panel 21.

In the vehicle structure 1 of the embodiment, water is discharged inward in the vehicle width direction by the roof garnish 6. Therefore, even when the rear door 232 that slides to the loading platform 3 side is provided as in this example, it is possible to suppress water from adhering to the trim of the rear door 232 when the rear door 232 is opened.

The present invention is not limited to these examples, but is indicated by the scope of the claims, and is intended to include all changes within the meaning and scope equivalent to the scope of the claims. For example, in the embodiment described above, the following changes are possible.

(1) In the embodiment described above, the roof garnish 6 has been described to discharge water toward the inside in the vehicle width direction. The roof garnish 6 may be configured to drain water outward in the vehicle width direction. For example, a wall portion (not shown) may be provided in a portion communicating with the second flow path 92 shown in FIG. 2, and a through hole (not shown) may be provided in a portion of the side portion 61 near the guide surface 630s. In this case, the second shelf 652 can be omitted.

(2) In the above-described embodiment, the water on the second shelf portion 652 whose momentum is reduced can naturally flow into the third channel 93 due to vibration or the like. The pillar garnish 80 or the roof garnish 6 may be configured to actively guide the water on the second shelf 652 whose momentum has decreased to the third flow path 93. As shown in FIG. 3 of this example, when the opening end of the second flow path 92 inside the vehicle is located further inside the vehicle than the upper end of the third flow path 93, the water on the second shelf 652 flows into the third flow path. There are cases where it is difficult to flow to the path 93. Therefore, a rib (not shown) can be provided on the upper surface of the pillar garnish 80. For example, the rib interrupts the middle of the second flow path 92 and is inclined so as to connect the second shelf 652 to the third flow path 93.
