In such a back door structure, a water drain hole is formed on the lower edge side of the door inner panel in order to discharge water that has entered the door to the outside of the vehicle.

JP 2006-298329 A

  However, in this structure, since the drain hole is formed in the vicinity of the adhesive, the adhesive may enter the drain hole. If the adhesive enters the drain hole, the drain hole may be blocked by the adhesive.

  In view of the above fact, an object of the present invention is to provide a vehicle opening / closing body structure that can prevent or suppress the drainage hole from being blocked by an adhesive.

According to a first aspect of the present invention, there is provided a vehicle opening / closing body structure comprising a door inner panel constituting an inner plate of an opening / closing body capable of opening and closing a vehicle body opening, an outer plate of the opening / closing body and the door inner panel. A door outer panel that forms an internal space between the door inner panel, a lower edge bonding portion that joins a lower edge portion of the door inner panel and a lower edge portion of the door outer panel, a lower portion of the door inner panel, and a door outer panel A drainage hole in which at least one of the lower portions has an opening facing the internal space, and a drainage portion in which the inside of the door cross section communicates with the outside of the door cross section, and the door of the drainage hole Provided at the door width direction position including the entire length in the width direction and projecting from at least one side of the lower part of the door inner panel and the lower part of the door outer panel toward the other side, and Yes upper edge adhesive portion and and a protrusion adjacent to the upper side of the door up and down direction with respect to the upper end of the lower edge adhesive portion in the space between the door section inward of the opening of the water drain hole And at least one of the lower part of the door inner panel and the lower part of the door outer panel, a first inclined part that inclines outward in the door thickness direction and extends along the door width direction upward in the door vertical direction. And a second inclined part that extends from the lower end of the first inclined part and inclines upward in the door vertical direction toward the inside in the door thickness direction and extends along the door width direction. In addition, the drain hole is formed by penetrating a portion including the lower end portion of the first inclined portion and the lower end portion of the second inclined portion .

  According to the opening / closing body structure for a vehicle of the present invention described in claim 1, at least one of the lower part of the door inner panel and the lower part of the door outer panel is provided with the water draining part, and the water draining part has an internal space. A water drain hole facing the opening is formed so as to penetrate the door cross section inside and the door cross section outside. For this reason, the water that has entered the door section is discharged from the drain hole to the outside of the door section.

Here, at the door width direction position including the entire length of the drain hole in the door width direction, a projecting portion that projects from at least one side of the lower part of the door inner panel and the lower part of the door outer panel toward the other side is provided. The protruding portion is adjacent to the upper side of the door in the vertical direction with respect to the upper end of the lower edge adhesive portion in the space between the upper end of the lower edge adhesive portion and the opening on the door cross section inner side of the drain hole. Yes. For this reason, when the water in the door cross section flows under its own weight, the amount of water reaching the lower edge adhesive portion in the vicinity of the drain hole is suppressed by the protruding portion, and the adhesive at the lower edge adhesive portion is water together with the water. The amount flowing out to the hole is also suppressed.
Moreover, according to this vehicle opening / closing body structure, the first inclined portion and the second inclined portion are formed in at least one of the lower portion of the door inner panel and the lower portion of the door outer panel. The first inclined portion is inclined outward in the door thickness direction toward the upper side of the door vertical direction and extends along the door width direction, and the second inclined portion extends from the lower end of the first inclined portion. It is inclined upward in the door vertical direction toward the inside in the door thickness direction and extends along the door width direction. For this reason, when the water in the door cross section flows under its own weight, the water travels along the boundary corner portion between the first inclined portion and the second inclined portion. Here, since the drain hole is formed by penetrating a portion including the lower end portion of the first inclined portion and the lower end portion of the second inclined portion, the boundary between the first inclined portion and the second inclined portion Water that travels along the corners is discharged from the drain hole to the outside of the door cross section. For this reason, the water transmitted through the boundary corner is basically discharged from the drain hole before reaching the lower edge bonding portion. Thereby, the quantity which the adhesive agent of a lower edge adhesion part flows out to a drain hole with water is suppressed more effectively.

It protrudes from the part located in the upper end side of the lower edge adhesion part, and both ends in the door width direction of the protrusion part are positions where the upward surface is lower in the door vertical direction than the upward surface of the second inclined part A step is formed between the second inclined portion and the upward surface of the second inclined portion .

  According to the vehicle opening / closing body structure of the present invention described in claim 2, at least a part of the projecting portion is located on the upper end side of the lower edge adhesion portion in the periphery of the opening on the door cross-section inner side of the drain hole. Since it protrudes from the site | part which is located, unless the adhesive agent of a lower edge adhesion part flows so that it may bypass a protrusion part, it does not flow into a drain hole.

  As described above, according to the vehicle opening / closing body structure according to claim 1 of the present invention, it is possible to prevent or suppress the drain hole from being blocked by the adhesive. Have

  According to the opening / closing body structure for a vehicle according to claim 2, it has an excellent effect that the inflow of the adhesive into the drain hole can be effectively suppressed.

  According to the opening / closing body structure for a vehicle according to claim 3, by suppressing the arrival of water to the lower edge adhesive portion, the amount of the adhesive of the lower edge adhesive portion flowing out to the drain hole together with water can be more effectively achieved. It has an excellent effect that it can be suppressed.

Moreover, the both ends in the door width direction of the protrusion part 30 form the level | step difference in the upward surface between the upward surfaces of 2nd inclination part 16D. The protrusion 30 is a component that can be grasped as a bead-like protrusion or a flange-like protrusion.

(Action / Effect)
Next, the operation and effect of the above embodiment will be described.

  In general, rain water during rain or car wash water during car washing may enter the cross section of the back door 14 shown in FIG. 1, and condensation may occur within the cross section of the back door 14. Rain water that has entered the cross section of the back door 14 or water that has condensed in the cross section travels down to the lower side of the back door 14. As shown in FIG. 3, a drainage portion 24 is provided at the lower portion of the door inner panel 16, and the drainage portion 24 has water that has an opening facing the internal space S in the door inner panel 16. The inside of the door cross section and the outside of the door cross section are communicated with each other by forming the through hole 24A. For this reason, the water that has entered the door cross section is discharged from the drain hole 24A to the outside of the door cross section.

  Here, in this embodiment, as shown in FIG. 4, the door outer panel 20 (see FIG. 3) extends from the lower portion of the door inner panel 16 to the door width direction position including the entire length of the drain hole 24 </ b> A in the door width direction. The protrusion part 30 which protrudes toward the lower side of is provided. As shown in FIG. 3, the protrusion 30 is located in the space between the upper end of the lower edge adhesive portion 26A and the opening on the door cross-section inner side of the drain hole 24A with respect to the upper end of the lower edge adhesive portion 26A. Adjacent to the upper side of the door vertical direction. For this reason, when the water in the door cross section flows under its own weight, the amount of water reaching the lower edge adhesive portion 26A in the vicinity of the drain hole 24A is suppressed by the protruding portion 30, and the adhesive of the lower edge adhesive portion 26A The amount of water flowing out to the drain hole 24A with water is also suppressed.

  Moreover, in this embodiment, a part of protrusion part 30 protrudes from the site | part located in the upper end side of the lower edge adhesion part 26A among the opening part periphery of the door cross-section inner side of the drain hole 24A. For this reason, the adhesive of the lower edge adhesive portion 26A does not flow into the drain hole 24A unless it flows so as to bypass the protruding portion 30.

  Further, in the vehicle opening / closing body structure according to the present embodiment, as shown in FIGS. 3 and 4, the first inclined portion 16 </ b> C formed in the lower portion of the door inner panel 16 is directed upward in the door vertical direction. The second inclined portion 16D extends from the lower end of the first inclined portion 16C and slightly inclines upward in the door vertical direction toward the inside of the door thickness direction while inclining forward (door thickness direction outer side). ing. For this reason, as shown in FIG. 4, when the water in the door cross section flows under its own weight, the water travels through the boundary corner portion 28 between the first inclined portion 16C and the second inclined portion 16D (see arrow B). . Here, since the drain hole 24A is formed by penetrating a portion including the lower end portion of the first inclined portion 16C and the lower end portion of the second inclined portion 16D, the first inclined portion 16C and the second inclined portion are formed. The water that travels through the boundary corner portion 28 with the portion 16D is discharged from the drain hole 24A to the outside of the door cross section. For this reason, the water transmitted through the boundary corner portion 28 is basically discharged from the drain hole 24A before reaching the lower edge bonding portion 26A. As a result, the amount of the adhesive at the lower edge adhesive portion 26A that flows out together with the water into the drain hole 24A is more effectively suppressed.

  Here, a supplementary explanation will be given below in comparison with the proportionality. For example, in the contrast structure in which the protruding portion 30 of the above embodiment is not formed and the drain hole is formed through the lower end flat plate portion of the door inner panel, water in the door cross section is on the lower edge bonding portion side. It becomes easy to flow. For this reason, when the distance between the formation position of the drain hole and the upper end position of the lower edge adhesive portion is short, the adhesive of the lower edge adhesive portion easily flows out to the drain hole together with water. As a result, when the drain hole is blocked with an adhesive, the drain function cannot be performed, and sound generated due to movement of accumulated water, rusting of metal parts (for example, lock reinforcement), or the like may occur. On the other hand, in order to suppress the outflow of the adhesive to the drain hole, when the position of the drain hole is greatly separated from the upper end position of the lower edge adhesive portion to the upper side in the door vertical direction, the upper side of the adhesive In this case, water accumulates on the lower side of the drainage hole, so that the drainage performance deteriorates. In this case as well, sound may be generated due to the movement of accumulated water, metal parts may rust, and the like.

  On the other hand, in the present embodiment, the protrusion 30 suppresses the adhesive from flowing out to the drain hole 24A of the lower edge adhesive portion 26A, and the position of the drain hole and the upper end position of the lower edge adhesive portion. Since the distance can be shortened, drainage performance is also ensured.

  As described above, according to the vehicle opening / closing body structure according to the present embodiment, the drain hole 24A can be prevented or suppressed from being blocked by the adhesive.

[Second Embodiment]
Next, a vehicle opening / closing body structure according to a second embodiment of the present invention will be described with reference to FIG. FIG. 5 is a longitudinal sectional view (a longitudinal sectional view corresponding to FIG. 3 of the first embodiment) of the lower portion of the back door to which the vehicle opening / closing body structure according to the second embodiment of the present invention is applied. It is shown. As shown in this figure, in the second embodiment, the formation position of the protrusion 34 is different from the vehicle opening / closing body structure according to the first embodiment. Other configurations are substantially the same as those of the first embodiment. Therefore, about the structure part except a protrusion part, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As shown in FIG. 5, a protruding portion 34 protrudes from the lower portion of the door outer panel 20 toward the lower portion of the door inner panel 16 to cover a part of the lower edge bonding portion 26 </ b> A. The protrusion 34 is adjacent to the upper side of the door upper and lower direction with respect to the upper end of the lower edge adhesive portion 26A in the space between the upper end of the lower edge adhesive portion 26A and the opening on the door cross-section inner side of the drain hole 24A. doing. Although not shown, the protrusion 34 is provided at a door width direction position including the entire length of the drain hole 24A in the door width direction and extends linearly along the door width direction. When viewed from the side, the intermediate portion of the protrusion 34 in the door width direction and the drain hole 24A are arranged to correspond to each other.

  According to the configuration of the present embodiment, when the water in the door cross section flows under its own weight, the amount of water reaching the lower edge adhesion portion 26A in the vicinity of the drain hole 24A is suppressed by the protrusion 34, and the lower edge adhesion is performed. The amount of the adhesive of the portion 26A that flows into the drain hole 24A together with water is also suppressed. Therefore, it is possible to prevent or suppress the drain hole 24A from being blocked by the adhesive.
