Description

  The present invention relates to a drainage structure for a flip-up type tailgate disposed on a rear surface of a vehicle.

  In vehicles with a tailgate (back door) such as a wagon car, when the tailgate is flipped up and opened in rainy weather etc., water droplets such as rainwater adhering to the outer surface of the tailgate wrap around the center of the rear surface of the tailgate. A drainage structure for preventing entry into the vehicle body opening is provided.

As this drainage structure, for example, a water droplet capturing member that captures a water droplet dripping downward from the side edge of the tailgate body when the tailgate body is opened is attached to the upper corner region of the tailgate body. It is known that the captured water droplet is discharged from the upper part of the tailgate body into a drainage groove at the upper end of the vehicle body opening (see, for example, Patent Document 1).
JP 2004-217152 A

  However, in this conventional tailgate drainage structure, a water droplet catching member is attached to the upper corner area of the tailgate body, and when the tailgate body is opened, the waterdrop captured by the water drop catching member is directed to the drainage groove at the upper end of the vehicle body opening When the tailgate body is opened, the upper corner area of the tailgate body may be reduced depending on the shape of the tailgate. The water drainage groove on the vehicle body side is greatly separated, and the water droplets captured by the waterdrop capturing member are detached from the drainage groove and dropped into the vehicle body opening.

  Accordingly, the present invention is intended to provide a tailgate drainage structure capable of draining water droplets captured in the upper corner region to a predetermined position outside the vehicle body opening regardless of the shape of the tailgate body. .

The invention according to claim 1, which solves the above-described problem, is provided in an opening (for example, an opening 4 in an embodiment described later) at the rear of the vehicle body so that the upper side of the opening can be opened and closed. In the drainage structure of the tailgate, in the upper corner region (for example, the upper corner region 7 in the embodiment described later) that extends from the upper side to the side of the tailgate body (for example, the tailgate body 3 in the embodiment described later), When the tailgate main body is opened, a waterdrop capturing member (for example, a waterdrop capturing member 8 in an embodiment described later) that captures water droplets dripping from the edge of the tailgate main body is provided, and the water droplet capturing member is provided on the tailgate main body. Drained water from the open end of the end (for example, open end 16 in an embodiment described later) by causing the captured water droplets to flow down toward the rear side of the vehicle body when the vehicle is opened Race track (e.g., the drainage guide groove 14 in the embodiment) provided with Rutotomoni, the drainage guide groove is formed along the upper corner region of the tailgate body, the tailgate body, the tailgate body A molding member (for example, a molding member 18 in an embodiment described later) is attached along the side, and a terminal portion of the molding member (for example, a terminal portion 18a in the embodiment described later) is attached to the water droplet capturing member. And a gap (for example, a gap 19 in an embodiment described later) is provided on the vehicle outer side between the terminal portion of the molding member and the water droplet capturing member. And
As a result, when the tailgate body is opened with water droplets attached to the outer surface, water droplets collected in the upper corner area of the tailgate body are captured by the water droplet capturing member and flow down toward the rear of the vehicle body along the drainage guide groove. To do. Then, the water droplets flowing down along the drainage guiding groove are discharged to a predetermined position off the opening at the rear of the vehicle body from the open end of the end.
In addition, since a gap is provided between the terminal portion of the molding member and the water droplet capturing member, when water droplets captured by the water droplet capturing member flow toward the rear side of the vehicle body, Water drops are no longer transmitted through. Moreover, the water droplet which flowed through the molding member in the upper corner direction drops to the drainage guiding groove through a gap between the terminal portion of the molding member and the water droplet capturing member.

The invention described in claim 2, in the drainage structure of the tailgate according to claim 1, wherein the drainage guide groove, the water droplet capture member in a substantially V-shaped cross section of the bent section provided (e.g., performed later The top of the bent portion (for example, the top portion 13a in the embodiment described later) is offset toward the center of the tailgate body with respect to the center in the width direction of the bent portion. It is characterized by being arranged.

According to the first aspect of the present invention, when the tailgate body is opened, water droplets collected in the upper corner region of the tailgate body are captured by the water droplet capturing member, and the water droplets are taken along the drainage guide groove of the water droplet capturing member. Because it can flow down toward the rear side of the vehicle and drain from the open end of the drainage guide groove, regardless of the shape of the tailgate body, the water droplets captured in the upper corner area can be reliably placed at a predetermined position outside the vehicle body opening. It can be drained.
In addition, according to the present invention, since the drainage guiding groove is formed along the upper corner area of the tailgate body, the drainage direction of water drops flowing into the upper corner area of the tailgate body is surely directed to the rear side of the vehicle body. be able to.

Further, according to the first aspect of the present invention, since the gap is provided between the water droplet capturing member and the end portion of the molding member, the water droplets collected in the upper corner region when the tailgate body is released are When discharging toward the rear side of the vehicle body through the capturing member, it is possible to prevent water droplets from flowing from the water droplet capturing member to the molding member side, and to allow water droplets transmitted from the molding member side to pass through the gap. It can be discharged to the water droplet capturing member side.

According to the second aspect of the present invention, since the top of the bent portion of the water droplet capturing member is arranged offset to the center side of the tailgate body with respect to the center in the width direction of the bent portion, the tailgate When the main body is opened, it is possible to prevent the water droplet capturing member from protruding outward and to improve the appearance quality around the tailgate.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing a tailgate 2 of a wagon-type vehicle 1 together with the outer shape of the vehicle body, and FIG. 2 is a rear view of the tailgate 2.
The tailgate 2 is attached so that the upper end portion of the tailgate body 3 can be opened and closed in the vertical direction to the opening portion 4 at the rear of the vehicle body via a hinge (not shown), and opens the opening portion 4 in a flip-up state. . The tailgate body 3 is attached to a gate panel 5 formed by joining a skin (reference numeral omitted), which is a panel material on the outside of the vehicle, and a frame material (reference numeral omitted) on the vehicle interior side, and to the vehicle outer surface on the upper side of the gate panel 5. The gate glass 6 is provided.

  The tailgate body 3 is formed in a substantially trapezoidal shape that is narrowed downward, and the upper corner regions 7 on both sides that are continuous from the upper side to the side are curved smoothly. As shown in FIG. 2, the gate panel 5 includes a substantially rectangular window frame portion 5 a in the upper half, and a gate glass 6 is attached to the vehicle outer side of the window frame portion 5 a. The gate glass 6 is formed to be slightly larger than the outer shape of the window frame portion 5a in the vehicle width direction, so that the sides on both sides and the upper corner region 7 protrude from the window frame portion 5a and are exposed to the outside of the vehicle. . In addition, 5b in the figure is an upper extension piece of the gate panel 5 that bulges upward from the center of the upper side of the gate glass 6. The upper extension piece 5b has a base portion that bulges along the upper side of the gate glass 6 toward the rear side of the vehicle body, and a rear surface side that is supported by the vehicle body via a hinge (not shown).

FIG. 3 is a side view showing a state in which the tailgate body 3 is flipped upward and opened.
A gas damper (not shown) is interposed between the tailgate body 3 and the vehicle body, and the open state of the tailgate body 3 is held by the gas damper. As shown in FIG. 3, the inclination angle of the tailgate body 3 in the maximum open state is set to an inclination angle at which the rear end side is slightly inclined upward with respect to the horizontal.
Further, as shown in FIG. 3, the upper region of the tailgate body 3, particularly the gate glass 6 portion, is largely curved toward the side end side with the center in the vehicle width direction as the center. Therefore, the gate glass 6 is curved not only in the front view direction but also in the side view direction, and is curved three-dimensionally as a whole.

  By the way, the water droplet capturing member 8 that captures water droplets dripping from the edge of the tailgate body 3 when the tailgate body 3 is opened is attached to the portions corresponding to the upper corner regions 7 on both sides of the back surface of the window frame portion 5a. It has been. The water droplet capturing member 8 is integrally formed of a resin material, and includes a base wall 9 fixed to the back surface of the peripheral edge of the window frame portion 5a, and a capturing wall 10 extending from the base wall 9. Yes.

4, 5, and 6 are cross-sectional views corresponding to the AA, BB, and CC sections of FIG. 3, respectively.
As shown in these cross-sectional views, the base wall 9 of the water droplet capturing member 8 is superposed on the back surface of the peripheral edge of the window frame portion 5 a and is fixed to the window frame portion 5 a by the clip 11 and the double-sided tape 12. The trapping wall 10 is formed in a substantially V-shaped cross section so as to extend in the direction of the peripheral edge of the gate glass 6 protruding outward from the window frame portion 5a and to cover the back surface of the peripheral edge of the gate glass 6 with a gap. The bent portion 13 having a substantially V-shaped cross section is continuous along the upper corner region 7 of the gate glass 6, and the inner surface thereof facing the gate glass 6 constitutes a drainage guiding groove 14. Further, the edge 10 a in the width direction of the trapping wall 10 extends to the outside of the outer peripheral end face of the gate glass 6, and forms a water drop inflow gap 15 with the outer peripheral end face of the gate glass 6. . The water droplet inflow gap 15 opens to the outside of the vehicle, and introduces water droplets collected in the upper corner region 7 along the outer surface of the gate glass 6 into the drainage guide groove 14.

The drainage guide groove 14 formed by the inner surface of the bent portion 13 extends curvedly along the upper corner region 7 of the gate glass 6, and the end portion on the side side of the gate glass 6 is an open end 16 having a substantially V shape. It has become. The position of the open end 16 is set so as to deviate from the position immediately above the opening 4 of the vehicle body when the tailgate body 3 is in the open state. Further, the depth of the drainage guiding groove 14 gradually becomes deeper from the upper side to the side of the gate glass 6, and when the tailgate body 3 is opened, water droplets flowing into the draining guiding groove 14 are moved to the rear side of the vehicle body. It is designed to flow down.
Further, the top portion 13 a when the bent portion 13 is viewed from the back surface side of the tailgate body 3 is arranged offset to the center side of the tailgate body 3 with respect to the center o in the width direction of the bent portion 13. .

FIG. 7 is a perspective view of the tailgate 2 when viewed from the direction of the arrow D in FIG.
As shown in the figure, a water receiving wall 17 extending in a direction substantially orthogonal to the end surface of the gate glass 6 on the back surface side of the gate glass 6 is formed in a stepped shape on the edge of the water droplet capturing member 8 on the open end 16 side. It is bent and formed. The water receiving wall 17 is arranged on the back surface side of the gate glass 6 so as to be separated from the back surface of the glass glass 6 by a predetermined distance.

By the way, a long molding member 18 is bonded and fixed to side end portions on both sides of the gate glass 6. The molding member 18 is formed of a resin material, and is attached in a range extending from the lower end of the gate glass 6 to the vicinity of the attachment position of the water droplet capturing member 8. The molding member 18 has a base side bonded to the gate glass 6, and an extending end extending in a lip shape from the base portion projects beyond the edge of the gate glass 6.
The terminal portion 18a on the upper side of the molding member 18 extends to a position where it overlaps with the end portion on the open end 16 side of the water droplet capturing member 8 on the vehicle outer side of the gate glass 6, and the end of the gate glass 6 of the terminal portion 18a. A lip-shaped tip protruding from the edge is positioned on the water receiving wall 17 of the water droplet capturing member 8. Since the water receiving wall 17 of the water droplet capturing member 8 is spaced apart from the back side of the gate glass 6 as described above, there is a gap 19 between the terminal portion 18a of the molding member 18 and the water droplet capturing member 8. Is provided. One end of the gap 19 is open to the outside of the vehicle, and the other end communicates with the water receiving wall 17 side.

In the above configuration, when the water droplets adhere to the outer surface of the gate glass 6, as shown in FIG. 3, when the tailgate body 3 is flipped up and opened, the water droplets on the gate glass 6 are forward of the tailgate body 3. It gathers in the upper left and right corner regions 7 along with the inclination and flows into the drainage guide groove 14 of the water droplet capturing member 8 through the gap 15 between the gate glass 6 and the water droplet capturing member 8. Then, the water droplets flowing into the drainage guiding groove 14 flow toward the rear side of the vehicle body along the groove shape (along the curved shape of the upper corner region 7), and downward through the open end 16 of the drainage guiding groove 14. Drained. At this time, since the open end 16 is disposed at a position away from the upper portion of the opening 4 of the vehicle body, the water droplets drained from the open end 16 are surely discharged out of the vehicle without dropping into the opening 4. .
Further, water droplets adhering to the outer surface of the gate glass 6 may flow into the upper portion of the gate glass 6 due to the springing-up force of the tailgate body 3, but the upper extension piece of the gate panel 5 is placed on the upper portion of the gate glass 6. Since the lower edge of 5b bulges out, the water droplet surely flows into the drainage guiding groove 14 in the upper corner region 7 along the lower edge of the upper extension piece 5b.

Further, the extended end of the molding member 18 that protrudes from the end surface of the gate glass 6 is positioned on the extension of the edge 10 a of the capturing wall 10 of the water droplet capturing member 8 on the vehicle exterior side of the gate glass 6. However, since a gap 19 is provided between the two, when the tailgate body 3 is opened, water droplets flowing down the water droplet capturing member 8 travel from the capturing wall 10 through the molding member 18 to the outer surface side of the gate glass 6. It will not flow out.
Further, when the tailgate body 3 is opened, the water droplets flowing forward from the side end portion of the gate glass 6 along the molding member 18 flow down onto the water receiving wall 17 of the water droplet capturing member 8 through the gap 19 to induce drainage. It is discharged from the open end 16 of the groove 14 to the outside of the vehicle.

In the drainage structure of the tailgate 2, when the tailgate body 3 is opened, water droplets collected on the upper corner region 7 along the outer surface of the gate glass 6 are captured by the waterdrop capturing member 8, and the waterdrops are captured by the waterdrop capturing member 8. Therefore, the upper corner region 7 of the tailgate 2 has a large curved shape because it can flow down toward the rear side of the vehicle body along the drainage guide groove 14 and be dropped at a predetermined position off the opening 4 of the vehicle body. Even in this case, it is possible to reliably discharge the water droplets to a position off the opening 4. Therefore, the degree of freedom in designing the tailgate 2 can be increased by adopting this drainage structure.
Further, in this drainage structure, the drainage guiding groove 14 of the waterdrop capturing member 8 is formed so as to follow the curved shape of the upper corner region 7 of the gate glass 6, so that the waterdrop that has flowed into the drainage guiding groove 14 is reliably detected. Can flow down toward the rear side of the vehicle body.

  Further, in the case of the embodiment, the top portion 13 a of the bent portion 13 constituting the drainage guiding groove 14 on the water droplet capturing member 8 is offset to the center side of the tailgate body 3 with respect to the center o in the width direction of the bent portion 13. Therefore, when the tailgate body 3 is opened, the bent portion 13 protrudes outward and is not visible, and there is an advantage that the appearance quality around the tailgate 2 is improved.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary.
