JP 2001-219738 A

  However, when it rains heavily, or when the car is washed with high water pressure, the outer seal part alone cannot completely prevent water leakage, and water enters the inner side of the outer seal part. In some cases, water could enter the cabin beyond the panel. In particular, as shown in FIG. 7, when the end surface 94 of the door glass 91 is formed in a rounded shape, water leaking from the outer seal portion 93 wraps around the inner surface at the end surface 94 and jumps into the vehicle beyond the inner panel 96. There was a case to come.

  Further, as shown in FIG. 8, even when the inner seal portion 95 and the base portion 97 for attaching the inner seal portion 95 are provided, the water cannot be blocked halfway and the water jumps into the vehicle. was there. That is, the water that has entered the inside of the vehicle at the end surface 94 (the rounded surface) of the door glass 91 hits the front end portion 97a of the base portion 97. May come. Then, as shown in FIG. 7, water that has jumped over the inner panel 96 may flow down, for example, along the wall surface of the side deflector 98 and leak into the vehicle compartment. Therefore, there has been a demand for a door water leakage prevention structure in which water does not easily leak into the passenger compartment even when heavy rain falls or when a car is washed at a high water pressure.

  The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a door water leakage prevention structure that prevents water leakage into the vehicle interior.

The present invention is a door water leakage prevention structure for preventing water leakage into the vehicle door at a vehicle door,
An outer panel provided outside the vehicle of the door;
An inner panel provided on the inner side of the vehicle than the outer panel;
A door glass provided between the inner panel and the outer panel, and configured to be movable so as to open and close a window portion formed above the upper end portion of the outer panel;
An outer seal portion provided at the upper end portion of the outer panel and sealing between the outer panel and the door glass;
A water leakage prevention dam formed on the vehicle outer main surface of the door glass inside the outer panel and protruding toward the vehicle outer side,
The water leakage prevention dam is provided in a door water leakage prevention structure, wherein the water leakage prevention dam is provided at a position where the water leakage prevention dam does not contact the outer seal portion in a movable range associated with the door glass.

Next, the effects of the present invention will be described.
In the door water leakage prevention structure, since the water leakage prevention dam is provided in the door glass, it is difficult for water to leak into the passenger compartment. That is, for example, when heavy rain falls or when the car is washed at a high water pressure, water may leak from the outer seal portion. Will change, and it will not be directed directly to the lower end surface of the door glass. As a result, water can be prevented from jumping over the inner panel, and water leakage to the passenger compartment can be prevented.

  Further, if the water leakage prevention dam and the outer seal portion are in contact with each other, there may be a problem that the outer seal portion is deformed and water leakage is likely to occur. However, in the present invention, the water leakage prevention dam does not contact the outer seal portion Since it is provided at the position, such a problem hardly occurs.

  As described above, according to the present invention, it is possible to provide a door water leakage prevention structure that prevents water leakage into the vehicle interior.

A preferred embodiment of the present invention described above will be described.
In the present invention (Claim 1), it is desirable that at least a part of the lower end surface of the door glass is formed in a rounded shape in which a cross section perpendicular to the vehicle outer main surface has a downward curved convex contour. (Claim 2).
In this case, the effect when the water leakage prevention dam according to the present invention is attached is particularly high. That is, the end face of the door glass is formed in a rounded shape in order to ensure safety such that it is difficult to cut a hand when a user of the vehicle touches or an operator touches during the door manufacturing process. Sometimes. However, if the lower end surface of the door glass is rounded, and if the water leakage prevention dam is not provided, when the water leaked from the outer seal portion reaches the lower end surface, Because it becomes easier to go around the inside of the vehicle, the amount of water flying toward the inside of the vehicle increases. Therefore, in the configuration in which at least a part of the lower end surface of the door glass is rounded, the effect when the water leakage prevention dam according to the present invention is attached is particularly high.

In addition, the vehicle is located on the inner side of the inner panel than the inner panel, and is provided in a part in the width direction of the door.
In order to avoid interference with the side deflector, the inner panel is formed with a lower upper end portion that is lower than the upper end portion of the other part, in a portion adjacent to the side deflector,
It is desirable that the water leakage prevention dam is attached at least to a portion corresponding to a portion where the lower upper end portion of the inner panel is formed (Claim 3).

In this case, a side deflector for preventing fogging of the door glass is provided, and in order to avoid interference with the side deflector, the upper end of the inner panel adjacent to the side deflector is not adjacent. Although the lower upper end portion is formed at a position lower than the upper end portion of the portion, it is possible to easily prevent water leakage to the passenger compartment while adopting this structure.
In other words, if the lower upper end is formed on the inner panel, if no water leakage prevention dam is provided, it will be easier for water to fly inside the vehicle, and the water will jump over the lower upper end and leak into the vehicle. It can be envisaged.
However, by attaching a water leakage prevention dam to the part corresponding to the lower upper end, even if water enters the outer seal part, it becomes difficult for water to jump into the vehicle interior, so that the water jumps over the lower upper end. Can be prevented. Thereby, the water leak to a compartment can be prevented.

Moreover, the site | part corresponding to the part in which the upper end part of the said inner panel is formed lower than the height position of 15 mm upwards with respect to the lower end surface of the said door glass in the closed position in which the said door glass shields the said window part It is desirable that at least the water leakage prevention dam is provided.
In this case, it is possible to enhance the effect of preventing water leakage from the door. That is, when water flies from the lower end surface of the door glass to the inside of the vehicle, the upper end portion of the inner panel is formed lower than the height position 15 mm above the lower end surface of the door glass in the closed position. The area where the water is located is relatively easy to jump over. However, by installing a water leak prevention dam at the part corresponding to this part, even if water enters from the outer seal part, the water does not go directly to the lower end surface of the door glass, so water jumps into the car It becomes difficult. Therefore, it is easy to prevent water from jumping over the inner panel and preventing water leakage to the passenger compartment.

Further, the water leakage prevention dam is at least in a portion corresponding to a portion where the upper end portion of the inner panel is formed lower than the lower end surface of the door glass in the closed position where the door glass shields the window portion. It is desirable to be provided (Claim 5).
That is, when water flies from the lower end surface of the door glass to the inside of the vehicle, the water is likely to jump over the portion where the upper end portion of the inner panel is formed lower than the lower end surface of the door glass in the closed position. However, by installing a water leak prevention dam at the part corresponding to this part, even if water enters from the outer seal part, the water does not go directly to the lower end surface of the door glass, so water jumps into the car It becomes difficult. Therefore, it is easy to prevent water from jumping over the inner panel and preventing water leakage to the passenger compartment.

(Example 1)
A door water leakage prevention structure according to an embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 1 and 3, the door water leakage prevention structure 1 of this example is provided with an outer panel 10 on the vehicle outer side of the door 1 a (the arrow a side in FIG. 1). And the inner panel 15 is provided in the vehicle inner side (arrow b side of FIG. 1) rather than the outer panel 10. FIG. Further, a door glass 12 is provided between the inner panel 15 and the outer panel 10 so as to be movable so as to open and close a window portion 11 formed above the upper end portion 10a of the outer panel 10. An outer seal portion 13 that seals between the outer panel 10 and the door glass 12 is provided on the upper end portion 10 a of the outer panel 10.

  A water leakage prevention dam 14 is formed on the vehicle outer main surface 12b of the door glass 12 inside the outer panel 10 so as to protrude toward the vehicle outer side. The water leakage prevention dam 14 is provided at a position where it does not come into contact with the outer seal portion 13 in the movable range associated with the door glass 12.

  As shown in FIGS. 1 and 2, the lower end surface 12a of the door glass 12 is formed in a rounded shape having a curved contour with a cross section perpendicular to the vehicle outer main surface 12b projecting downward.

  As shown in FIGS. 1 and 4, a side deflector 16 that prevents fogging of the door glass 12 is provided in a portion of the door 1 a in the lateral width direction on the vehicle inner side than the inner panel 15. As shown in FIG. 4, in the inner panel 15, a lower upper end portion 151 lower than the upper end portion 152 of the other part is formed in a portion adjacent to the side deflector 16 in order to avoid interference with the side deflector 16. And the water leak prevention dam 14 is attached to the site | part corresponding to the part in which the low-order upper end part 151 of the inner panel 15 is formed.

  Next, as shown in FIG. 1, the upper end portion 15 a of the inner panel 15 is formed lower than the height position h <b> 1 of the lower end surface 12 a of the door glass 12 in the closed position where the door glass 12 shields the window portion 11. At least a water leakage prevention dam 14 is provided in a portion corresponding to the portion.

  In addition, as shown in FIG. 1, a gap 18 is formed between the inner panel 15 and the side deflector 16. An upper opening 18 a of the gap 18 is formed between the upper end 15 a of the inner panel 15 and the side deflector 16.

  Further, the side deflector 16 is formed with an inclined portion 16a that is inclined so as to approach the door glass 12 as it goes upward. And in order to avoid interference with the inclined part 16a, the upper end part 15a of the inner panel 15 in the part adjacent to the side deflector 16 is replaced with the upper end part 152 (in the part not adjacent to the side deflector 16) ( The lower upper end 151 is formed at a lower position (see FIG. 4).

As shown in FIG. 1, the side deflector 16 prevents the fogging of the door glass 12 by sending warm air H or the like from the vehicle lower side to the door glass 12.
As shown in FIG. 3, a side deflector 16 is attached at a position adjacent to the side mirror 4 so that the driver can visually recognize the side mirror 4 when the door glass 12 is fogged.

  Next, as shown in FIGS. 1 and 2, between the side deflector 16 and the door glass 12, an inner seal portion 2 that is in sliding contact with the door glass 12 from the inside of the vehicle, and a base portion that holds the inner seal portion 2. 3 is provided. The tip part 30 of the base part 3 is formed in a shape that is inclined so as to become lower toward the outside of the vehicle.

  In addition, as shown in FIG. 2, the water leakage prevention dam 14 is located at a position where a predetermined gap d is formed between the outer seal portion 13 and the water leakage prevention dam 14 with the door glass 12 being completely closed. It is attached. For example, even when the outer seal portion 13 is mounted at a low position due to manufacturing variations, or when the water leakage prevention dam 14 is mounted at a high position, the gap d is formed between the outer seal portion 13 and the water leakage prevention dam 14. It is set to a value that can be reliably separated, for example, about 5 to 7 mm.

Next, the function and effect of this example will be described.
As shown in FIGS. 1 and 2, the door water leakage prevention structure of the present example is provided with the water leakage prevention dam 14 on the door glass 12, so that it is difficult for water to leak into the vehicle. That is, for example, when heavy rain falls or when the car is washed with high water pressure using the hose 5 or the like, the water 6 may leak from the outer seal portion 13. As a result, the water 6 is once blocked, the flow direction is changed, and the water 6 is not directly directed to the lower end surface 12a of the door glass 12, so that it is difficult for water to fly toward the inside of the vehicle. For example, as shown in FIG. 5, the direction in which the water 6 leaked from the outer seal portion 13 flows in the direction along the main surface of the door glass 12 is changed by the water leak prevention dam 14. Or water is dripped along the outer panel 10 side of the water leakage prevention dam 14 as shown by the arrow C in FIG. As a result, water does not reach the lower end surface 12a of the door glass 12 with a certain amount of momentum, and water can be prevented from flying to the inside of the vehicle. This makes it easier to prevent water leakage into the passenger compartment.

  Further, if the water leakage prevention dam 14 and the outer seal portion 13 are in contact with each other, there is a possibility that the outer seal portion 13 is deformed and water leakage easily occurs. However, in this example, the water leakage prevention dam 14 is connected to the outer seal. Since it was provided at a position where it does not contact the portion 13, such a problem is unlikely to occur.

Next, as shown in FIG. 2, the end surface 12a of the door glass 12 is formed in a round shape. When the user of the vehicle touches the end surface 12a or the operator touches the door 1a during the manufacturing process of the door 1a, it has such a shape for safety reasons such that it is difficult to cut the hand.
Thus, if the end surface 12a of the door glass 12 is rounded, the water leaked from the outer seal portion 13 will wrap around the inside of the vehicle at the end surface 12a and the water will easily fly toward the inside of the vehicle. Therefore, the effect when the water leakage prevention dam 14 according to the present invention is attached is particularly high.

Further, as shown in FIG. 1, a side deflector 16 for preventing fogging of the door glass 12 is provided, and in order to avoid interference with the side deflector 16, the upper end of the inner panel 15 in a portion adjacent to the side deflector 16. The portion 15 a is a lower upper end portion 151 formed at a lower position than the upper end portion 152 (see FIG. 4) of the inner panel 15 in a portion not adjacent to the side deflector 16. In this example, it is possible to easily prevent water leakage to the passenger compartment while adopting this structure.
That is, if the water leakage prevention dam 14 is not provided in a portion corresponding to the portion where the lower upper end portion 151 of the inner panel 15 is formed, water easily jumps to the inside of the vehicle, and the water becomes lower. It can be assumed that the water will jump over and leak into the vehicle.
However, by attaching the water leakage prevention dam 14 to the portion corresponding to the lower upper end portion 151, even when water enters from the outer seal portion 13, it becomes difficult for water to fly into the vehicle interior. Thereby, it is possible to prevent water from jumping over the lower upper end 151 and to prevent water leakage to the passenger compartment.

Moreover, as shown in FIG. 1, the part which the upper end part 15a of the inner panel 15 is formed lower than the height position h1 of the lower end surface 12a of the door glass 12 in the closed position where the door glass 12 shields the window part 11 The water leak prevention dam 14 is provided at least in the part corresponding to.
Thereby, it becomes possible to improve the water leak prevention effect of the door 1a. That is, if water flies inside the vehicle, the water jumps over the portion where the upper end 15a of the inner panel 15 is lower than the height position h1 of the lower end surface 12a of the door glass 12 in the closed position. Cheap. However, as in this example, by attaching the water leakage prevention dam 14 to a portion corresponding to this portion, even when water enters from the outer seal portion 13, the water directly enters the lower end surface 12 a of the door glass 12. Since it does not head, water can be prevented from jumping into the vehicle. Therefore, it becomes difficult for water to jump over the inner panel 15, and water leakage to the passenger compartment can be prevented.

In addition, as shown in FIG. 1, a gap 18 is formed between the inner panel 15 and the side deflector 16. An upper opening 18 a of the gap 18 is formed between the upper end 15 a of the inner panel 15 and the side deflector 16.
The gap 18 is for preventing abnormal noise from being generated due to interference between the inner panel 15 and the side deflector 16.
In this case, when water flies to the inside of the vehicle, it enters the upper opening 18a and flows down along the wall surface of the side deflector 16 or the inner panel 15, so that water easily leaks into the room. However, by providing the water leakage prevention dam 14 as in this example, it is possible to prevent water from flying to the inside of the vehicle, so that high water leakage prevention performance can be ensured while employing the above structure.

Next, as shown in FIG. 1, the side deflector 16 is formed with an inclined portion 16 a that is inclined so as to approach the door glass 12 as it goes upward. The inclined portion 16 a has such a shape in order to blow air toward the door glass 12.
In this case, in order to avoid interference with the inclined portion 16a, the upper end portion 15a of the inner panel 15 has to be lowered, but in this case, water has temporarily entered the vehicle interior from the lower end surface 12a of the door glass 12. When it becomes easy to enter the upper opening 18a. And since the water flows down along the wall surface of the side deflector 16 or the inner panel 15, if there is no water leak prevention dam 14, it will become easy to leak into a room | chamber interior. However, by providing the water leakage prevention dam 14 as in this example, it is possible to prevent water from flying to the inside of the vehicle, so that a high water leakage prevention function can be ensured while employing the above structure.

Further, as shown in FIG. 2, the tip portion 30 of the base portion 3 is formed in a shape that is inclined so as to become lower toward the vehicle outer side.
In this case, if the water that has entered from the outer seal portion 13 jumps into the vehicle interior, the water easily flows around at the tip portion 30 of the base portion 3 (see FIG. 8). Although the structure easily leaks water, by providing the water leak prevention dam 14 as in this example, a high water leak prevention function can be secured while adopting the above structure.

  Next, as shown in FIG. 2, the gap d between the outer seal portion 13 and the water leakage prevention dam 14 is set to a value that can reliably separate the outer seal portion 13 and the water leakage prevention dam 14 even if manufacturing variation or the like occurs. Has been. Therefore, it is possible to prevent problems such as easy leakage of water from the outer seal portion 13 due to contact between the outer seal portion 13 and the water leakage prevention dam 14.

  As described above, this example can provide a door water leakage prevention structure that prevents water leakage into the vehicle interior.

(Example 2)
In this example, as shown in FIG. 6, the height of the upper end portion 15 a of the inner panel 15 is increased at the portion where the water leakage prevention dam 14 is attached.
That is, the door water leakage prevention structure 1 of this example is as shown in FIG. 6 from a height position h2 15 mm above the lower end surface 12a of the door glass 12 in the closed position where the door glass 12 shields the window portion 11. In addition, at least a water leakage prevention dam 14 is provided in a portion corresponding to a portion where the upper end portion 15a of the inner panel 15 is formed low.
Other configurations are the same as those of the first embodiment.

Next, the function and effect of this example will be described.
As shown in FIG. 6, in this example, compared with Example 1, the upper end 15a of the inner panel 15 in the portion where the water leakage prevention dam 14 is provided is raised, so that the water is in the upper end 15a. It is difficult to jump over the vehicle, and water leakage to the passenger compartment can be further reduced.
In addition, the same effects as those of the first embodiment are obtained.
