Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water draining structure for an automobile door.

[0002]

2. Description of the Related Art In order to drain rainwater or the like that has infiltrated inside a door for an automobile, particularly between a door inner panel and a service hole cover attached to the surface on the inside of the vehicle interior, various drainers have been conventionally used. A structure has been devised (as an example, see Japanese Utility Model Laid-Open No. 62-15018). The structure disclosed in this publication will be briefly described below.

As shown in FIG. 5, an automobile door 10 is provided.
0 is a door outer panel 102 and a door inner panel 10
And 4 form a closed cross section. Furthermore, a service hole 106 is formed in the door inner panel 104. The service hole 106 is closed by a service hole cover 110 adhered to the surface of the door inner panel 104 on the vehicle interior side by a butyl tape 108. A door trim 112 is provided on the vehicle interior side of the service hole cover 110.

As shown in FIG. 6, an opening 114 for draining water is formed in the lower portion of the door inner panel 104 described above. The lower end 110A of the service hole cover 110 is inserted into the opening 114. In addition, a drain groove 116 that is inclined downward toward the opening 114 is formed on the surface of the door inner panel 104 on the vehicle interior side. The above-mentioned butyl tape 108 is accommodated in the drain groove 116.

Here, in the structure disclosed in this publication,
Draining protrusions 118 projecting downward are formed on both sides inside the opening 114. As a result, the rainwater 120 flowing down along the upper edge of the butyl tape 108 enters the lower edge side of the butyl tape 108, and due to the capillary phenomenon, the door inner panel 104 and the service hole cover 110.
It is intended to prevent it from sneaking in between the vehicle and the vehicle, and by extension into the vehicle interior.

[0006]

However, in the case of the structure disclosed in the above publication, since the draining protrusion 118 is projected downward, the phenomenon is as follows. That is, in the rainwater 120 flowing down along the upper edge of the butyl tape 108, a part 120A of the rainwater 120 flows down from the cut end surface of the butyl tape 108 along the draining protrusion 118 as it is, and the other part 120B of the butyl tape 108 is butyl. From the cut end surface of the tape 108, the water passes over the draining projection 118, penetrates into the lower edge side of the butyl tape 108, and wraps around between the door inner panel 104 and the service hole cover 110 due to a capillary phenomenon. Therefore, the other part 120
There is a problem that B still penetrates into the passenger compartment.

In consideration of the above facts, the present invention can surely prevent rainwater or the like that has entered between the door inner panel and the service hole cover from further entering the interior of the vehicle. The purpose is to obtain the water drainage structure.

[0008]

According to the present invention, there is provided a door inner panel having a service hole at an appropriate place and a drainage opening formed in a lower portion, and the door inner panel is provided so that an end portion thereof is obliquely facing from above. Butyl tape,
A water draining structure applied to a vehicle door including a service hole cover that is attached to a surface of a door inner panel on the vehicle interior side and has a lower end inserted into a water draining opening. A recessed groove that extends obliquely upward along the end of the butyl tape from a portion that is separated downward with respect to the end of the butyl tape on the side of the opening is provided in the door inner panel.
It is characterized by that.

[0009]

According to the above construction, rainwater or the like that has entered between the door inner panel service hole and the door inner panel and the service hole cover flows down along the upper edge of the butyl tape and reaches the drain opening. .

According to the present invention, the recessed groove extending obliquely upward along the edge of the butyl tape from the side of the drainage opening and the portion spaced downward from the edge of the butyl tape is used as the door. Since it is provided on the inner panel, rainwater and the like that have flowed down to the drainage opening wrap around to the lower edge side of the end of the butyl tape, but are all drained to the drainage opening by the concave groove. That is, by providing the concave groove, a space is formed in this portion. Therefore, the door inner panel and the service hole cover are not in contact with each other at the recessed groove forming portion. Therefore, infiltration of rainwater due to the capillary phenomenon does not occur. As a result, rainwater or the like can be reliably prevented from entering the vehicle interior.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In these figures, the arrow FR, which is shown appropriately, indicates the vehicle front side, the arrow UP indicates the vehicle upper side, and the arrow IN indicates the vehicle interior side.

FIG. 4 shows a front door 10 of the automobile, and FIG. 3 shows a sectional view taken along line 3-3 of FIG. As shown in these figures, the front door 10
Includes a door outer panel 12 arranged outside the vehicle compartment and a door inner panel 14 arranged inside the vehicle compartment. The lower end of the door outer panel 12 and the lower end of the door inner panel 14 are joined by hemming. The door outer panel 12 and the door inner panel 14 make the front door 10 a closed cross-section structure.

Note that weather strips 16 and 18 are fitted to the upper end of the door outer panel 12 and the upper end of the door inner panel 14, respectively, and the door glass 20 moves up and down between these weather strips 16 and 18. It is supposed to do. A door trim 22 is attached to the interior of the door inner panel 14.

A service hole 24 is formed in the center of the door inner panel 14 described above, and a drain opening 26 is formed in the lower portion thereof. A drain port 28 (see FIG. 3) is formed at the lower end of the door inner panel 14. Furthermore, the door inner panel 14
A service hole cover 32 is attached to the inside surface of the vehicle by a butyl tape 30 that is routed along the outer periphery of the service hole 24.

As shown in the enlarged view of FIG. 1, the water draining opening 26 described above has a convex shape when viewed from the vehicle interior side, and has a lower opening 26A and a narrower width than the lower opening 26A. And an upper opening 26B. Both ends 30 </ b> A of the butyl tape 30 face both sides of the upper opening 26 </ b> B of the water draining opening 26 from diagonally above. The lower end 32A of the service hole cover 32 extends downward in the form of a tongue, and the lower end 32A is the lower opening 26 of the drainage opening 26.
It is inserted in A from the vehicle interior side. Then, in this state, the lower end portion 32A of the service hole cover 32 is adhered to the surface of the door inner panel 14 on the vehicle interior side by the tape 34 (also shown in FIG. 2).

Further, the door inner panel 14 is formed with a pair of concave grooves 36 on both sides of the water draining opening 26. More specifically, the base ends of the concave grooves 36 are located on both sides of the lower opening 26A of the water draining opening 26 and communicate with the inside of the lower opening 26A. In addition, the middle portion of the concave groove 36 extends obliquely upward along both ends 30A of the butyl tape 30. The concave groove 36 is formed by the butyl tape 3
It is formed below the both ends 30A of 0 and apart from the both ends 30A. Further, the end of the groove 36 is located outside the side edge of the service hole cover 32. The above-mentioned concave groove 36 has an arc-shaped cross section and is integrally formed when the door inner panel 14 is press-molded.

The operation of this embodiment will be described below. Figure 3
As shown in FIG. 2, rainwater or the like is exposed to the weather strip 16 on the side of the door outer panel 12 during rain or car washing.
And the door glass 20 penetrate into the front door 10 (the entry path is indicated by an arrow A). Rainwater and the like that have entered the front door 10 further pass through the service hole 24 of the door inner panel 14 and enter between the door inner panel 14 and the service hole cover 32 (the entry path is indicated by an arrow B). Shown). Then, the invading rainwater or the like flows down along the upper edges of both end portions 30A of the butyl tape 30 and is drained from the water draining opening 26 (the drainage path is indicated by an arrow C). After that, the water is drained to the outside of the front door 10 through the drainage port 28 formed at the lower end portion of the door inner panel 14 (the drainage path is indicated by an arrow D). The above is an outline of how rainwater and the like that have entered the front door 10 are discharged to the outside of the front door 10.

Here, as shown in FIG. 1, the rainwater or the like that has entered from the service hole 24 basically flows down along the upper edges of both ends 30A of the butyl tape 30, and inside the water drain opening 26. (The arrow D indicates the drainage route.
). However, some rainwater, etc.
Tries to penetrate between the door inner panel 14 and the service hole cover 32 along the end surface and the lower edge of the both end portions 30A (the arrow indicates the entry path). However,
In this embodiment, since the groove 36 extending obliquely upward is formed in this portion, the space 38 (see FIG. 2) is formed. For this reason, at the portion where the groove 36 is formed, the door inner panel 1
4 and the service hole cover 32 are in a non-contact state.
Therefore, due to the capillary phenomenon, rainwater or the like that has entered along the direction of the arrow F does not enter between the door inner panel 14 and the service hole cover 32 and enter the door trim 22 side.

As described above, in this embodiment, the water draining opening 26 formed in the lower portion of the door inner panel 14 is spaced below the both end portions 30A of the butyl tape 30 and the both end portions 3 are formed.
Since the concave groove 36 extending obliquely upward along 0A is formed, it is possible to reliably prevent the intrusion of rainwater or the like into the vehicle interior due to the capillary phenomenon.

Further, due to this effect, in the case of the present embodiment, the adhesion accuracy of the butyl tape 30 and the adhesion accuracy of the service hole cover 32 can be relaxed. That is, in the case of a structure in which the intrusion of rainwater or the like due to the capillary phenomenon cannot be completely eliminated like the conventional structure, it is necessary to increase the bonding accuracy of the butyl tape 30 and the bonding accuracy of the service hole cover 32. In the case of this embodiment,
Since the infiltration of rainwater and the like due to the capillary phenomenon can be eliminated, the accuracy can be relaxed. Therefore, the workability of adhering the butyl tape 30 and the workability of adhering the service hole cover 32 can be improved.

Furthermore, since the end of the recessed groove 36 in this embodiment is located outside the side edge of the service hole cover 32, the recessed groove 36 functions as a ventilation port. Therefore, it is possible to prevent the service hole cover 32 from making a noise when the vehicle is traveling.

Further, since the concave groove 36 in this embodiment is extended obliquely upward from both sides of the lower opening 26A of the water draining opening 26, even if the vehicle body is tilted when traveling on a slope or the like, the above-mentioned The drainage effect and ventilation effect can be surely obtained.
That is, for example, when the concave groove is extended horizontally, when the vehicle body is tilted, the amount of rainwater or the like entering the concave groove 36 is too large, and depending on the case, rainwater or the like may be collected from the end of the concave groove 36. It is possible that it will enter the vehicle interior,
If the groove 36 is formed obliquely upward as in this embodiment, such a problem does not occur.

Further, since the concave groove 36 in this embodiment can be formed at the same time as the press molding, it is easy to manufacture and the cost is low. In the case of the conventional structure, since the water draining protrusion 118 extends downward, it is difficult to simultaneously form the door inner panel 14 at the time of press forming. Further, when the draining protrusion 118 extending downward is formed, the lower end portion 32A of the service hole cover 32 is formed.
Although there is a risk that it may come into contact with the operator's hand when inserting into the drainage opening 26, such a problem does not occur according to the present embodiment.

[0024]

As described above, in the water drainage structure for an automobile door according to the present invention, the end portion of the butyl tape is separated from the side portion of the water drainage opening and the portion spaced downward from the end portion of the butyl tape. The door inner panel is provided with a groove that extends diagonally upward along the line, so it is possible to prevent rainwater that has entered between the door inner panel and the service hole cover from further entering the vehicle interior. It has an excellent effect of being able to.
