Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in a drip weather strip structure which is attached to an upper end edge of an opening portion of a vehicle body of an automobile and guides collected rainwater and the like in a vehicle longitudinal direction.
[0002]
[Prior art]
For example, as one of a weather strip that seals between a rear sliding door of a so-called one-box vehicle and an opening edge of the vehicle body, the weather strip is disposed at an upper position of the opening edge of the vehicle body along the vehicle front-rear direction, for example, from a roof side. A drip weatherstrip that collects rainwater or the like that has entered and guides it in the vehicle longitudinal direction is generally known (a similar structure is described in JP-A-62-20747).
[0003]
4 and 5, the drip weather strip 1 is applied to a one-box vehicle, and includes a vehicle body opening 2 on the front door side and a vehicle body opening 3 on the rear side of the vehicle body C. , A center pillar 4 is provided along the vertical direction of the vehicle body, and an outer panel 5 at the upper end of the vehicle body opening 2 on the front door side and an outer panel at the upper end of the vehicle body opening 3 on the sliding door side. 6 are formed in a step shape. A door lock mechanism 7 for a sliding door is provided below the center pillar 4.
[0004]
As shown in FIG. 5, the drip weather strip 1 is disposed along a retainer (not shown) fixed to an outer panel 6 located above the vehicle body opening 3 on the slide door side along the vehicle front-rear direction. A base portion 8 fixed to the retainer, a hollow seal portion 9 provided integrally with an upper end portion of the base portion 8 and contacting an inner edge of an upper end of the slide door when the slide door is closed, and a lower end portion of the base portion 8. The seal lip 10 is provided integrally with the seal lip 10 and rises obliquely upward from the vehicle. A channel portion 11 is formed between the base 8 and the seal lip 10.
[0005]
When the slide door is closed, the inner edge of the upper end of the slide door is elastically brought into contact with the hollow seal portion 9 to be deformed, and a portion of the outer edge of the seal lip 10 below the upper edge of the slide door is formed. In contact with the rim, the seal lip 10 is deformed inward to form a substantially cylindrical channel portion 11 with the base 8.
[0006]
Therefore, rainwater or the like flowing down from the roof 12 to the side of the vehicle body is collected in the channel portion 11 and guided in the vehicle front-rear direction, and is directly discharged from the drip weather strip 1, for example, from the terminal portion 1a on the vehicle body front side. It flows downward along the center pillar 4.
[0007]
[Problems to be solved by the invention]
However, in the above-mentioned conventional drip weather strip structure, the terminal portion 1a of the drip weather strip 1 is merely located substantially at the center of the center pillar 4 in the vehicle longitudinal direction and is directed downward. Rain water and the like guided to the channel portion 11 flow down along the outer surface of the center pillar 4 as shown in FIG. 5, and a part of the rain water may enter the door lock mechanism 7.
[0008]
As a result, rust is likely to be generated on each component of the lock mechanism 7 and durability may be reduced. In cold weather, the water that has entered the door lock mechanism 7 freezes, and the slide door may not be opened.
[0009]
The present invention has been devised in view of the technical problem of the conventional example, and guides a flowing direction of rainwater or the like collected and guided by a drip weather strip in a direction avoiding a door lock mechanism. An object of the present invention is to provide a drip weather strip structure capable of preventing water from entering a lock mechanism.
[0010]

The invention according to claim 1 is arranged at the upper edge of the door opening of the vehicle body in the front-rear direction of the vehicle body, the terminal portion extends to near the pillar of the vehicle body, and collects collected rainwater and the like in the front-rear direction. In the drip weather strip structure of an automobile for guiding in a direction, a terminal portion of the drip weather strip is provided with a bag-shaped water storage portion opened in a direction avoiding a door lock mechanism provided on the pillar. I have.
[0011]
Therefore, according to the present invention, rainwater or the like flowing down to the terminal portion of the drip weather strip is temporarily stored in the water storage portion, and flows down from this opening while being guided in a direction avoiding the door lock mechanism of the pillar. Therefore, it is possible to prevent water from entering the door lock mechanism.
[0012]
The invention according to claim 2 is arranged at the upper edge of the door opening of the vehicle body in the front-rear direction of the vehicle body, the terminal portion extends to near the pillar of the vehicle body, and collects collected rainwater or the like. In the drip weather strip structure of a vehicle for guiding in the front-rear direction, a guide portion that opens in a direction avoiding a door lock mechanism provided on the pillar is continuously formed at a terminal portion of the drip weather strip. I have.
[0013]
In the invention according to claim 3, the drip weatherstrip is formed from a base disposed at an upper edge of a door opening of the vehicle body in the front-rear direction of the vehicle, and from a vehicle outer end of the base. And a seal portion that is erected in an upward direction outside the vehicle, wherein the water storage portion or the guide portion is formed continuously by extending a terminal portion of the seal portion.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a drip weather strip structure according to the present invention will be described in detail with reference to the drawings. This embodiment is also applied to a one-box vehicle mounted on an opening of a slide door.
[0015]
1 and 2 show a first embodiment of the present invention, in which an outer panel 22 forming a vehicle body opening 21 of a slide door 20 has a length substantially bent into an L-shape at the upper end on the roof side. A plate-like retainer 23 is fixed along the vehicle front-rear direction, and a drip weather strip 24 is provided along the retainer 23.
[0016]
As shown in FIGS. 1 and 2, the drip weather strip 24 is almost integrally formed in a long shape by extruding rubber, but the end is formed by molding, and the drip weather strip 24 is formed on the retainer 23. A welt-like base 26 fixed along, a hollow seal part 27 integrally provided at the upper end of the base 26, and a seal part erected at the lower end of the base 26 so as to be inclined upward in the vehicle exterior direction. , And is fixed to the outer panel 22 by the clip 25.
[0017]
The base 26 has a substantially C-shaped cross section formed of hard solid rubber, and has a triangular cross-section at its lower end which resiliently contacts the lower surface of a lower end 23 a of the retainer 23 which is bent into a U-shape. And a flat locking hole 26b for locking the rising piece 23b at the tip of the lower end 23a of the retainer 23 is formed inside.
[0018]
The hollow seal portion 27 has a substantially arc-shaped cross section, an inner end portion 27a continuous from the base portion 28 is formed in a substantially flat plate shape with hard solid rubber, and upper and lower ends of the inner end portion 27a. The outer end portion 27b connecting the two portions is bent substantially in an arc shape, and the arc portion other than the hard rubber Y-shaped portion 27c continuous with the base portion 26 is formed of soft sponge rubber. Is fixed to the outer panel 22, the upper end of the inner side end portion 27a is pushed back to the outer side of the vehicle as shown by a two-dot chain line in FIG. 1 and is deformed, and when the slide door 20 is closed, the slide door is closed. The inner lip 20a of the upper end 20 is elastically deformed by elastically contacting the arc portion of the vehicle outer end portion 27c to seal the inside and outside of the vehicle. The base end 28a is formed continuously and integrally with the sponge rubber covering the outer surface of the lower end of the base 26, and the inner surface of the end 28b is formed in a substantially arc-shaped cross section. When the door 20 is closed, the outer surface of the distal end portion 28b elastically contacts the upper inner surface of the door inner panel 20b of the slide door 20 and is deformed in the vehicle direction, so that the channel portion 29 is formed between the base end portion 28a and the outer surface of the base portion 26. Is formed.
[0019]
As shown in FIG. 2, the drip weather strip 24 has at least a front end portion 24a, which is a terminal portion on the front side of the vehicle body, curved downward at substantially the center of the outer panel of the center pillar 30 constituting the vehicle body opening 21. At the lower end of the front end 24a, a bag-shaped water storage portion 31 is formed continuously and integrally.
[0020]
The cross-sectional shape of the water containing portion 31 is set to be substantially the same as the cross-sectional shape of the seal lip 28, is formed continuously with the seal lip 28, and is formed in a bag shape with the lower end edge 31a closed. The opening 31b is formed so as to be directed toward the front of the center pillar 30 in the vehicle body. In other words, the opening 31b of the water storage unit 31 is open to the front of the vehicle body.
[0021]
Therefore, according to this embodiment, during running of the vehicle, for example, rainwater flows down from the roof side through the outer panel 22 and is mostly blocked by the hollow seal portion 27, but part of the channel portion is cut off. 29, and is guided from here to the vehicle front-rear direction. The rainwater guided forward in the vehicle body in the channel portion 29 is guided downward from the front end portion (the front end portion 24a of the drip weather strip 24) of the channel portion 29, as indicated by an arrow in the drawing. After entering the storage section 31, it is temporarily stopped here. Further, the air is discharged from the lower end of the opening 31b to the upper surface of the outer panel of the center pillar 30, but at this time, the air is guided forward by the opening 31b.
[0022]
For this reason, the rainwater flows down in a form avoiding the direction of the door lock mechanism (not shown) for the slide door 20 provided on the rear side of the vehicle body of the center pillar 30. Can be prevented. As a result, it is possible to prevent rust due to water on the components of the door lock mechanism, and to prevent freezing inside during cold weather.
[0023]
FIG. 3 shows a second embodiment of the present invention, in which a guide portion 32 is integrally formed at a lower end portion of a front end portion 24a of a drip weather strip 24.
[0024]
That is, the guide portion 32 is formed continuously and integrally with the seal lip 28, is bent substantially in an L-shape in the forward direction of the vehicle body, has a lower end edge 32a formed substantially horizontally, and has an opening 32b. Is pointing toward the front of the vehicle.
[0025]
Therefore, according to this embodiment, as in the first embodiment, the rainwater flowing into the channel portion 29 flows down from the front end portion 24 of the drip weather strip 24 as shown by the arrow in FIG. The fluid flows into the inside 32, and is guided further downward from this, and is transmitted to the upper surface of the center pillar 30 at the opening 32b. At this time, it is guided more positively toward the front of the vehicle body through the opening 32b and flows down.
[0026]
For this reason, the rainwater that has traveled along the upper surface of the center pillar 30 flows down while avoiding the door lock mechanism on the rear side. Therefore, it is needless to say that the same operation and effect as those of the first embodiment can be obtained. In particular, the lower end portion of the guide portion 32 is bent forward so as to positively guide rainwater forward. , The intrusion into the door lock mechanism can be more reliably prevented.
[0027]
Further, since the water storage portion 31 and the guide portion 32 can be formed at the same time when the end portion of the drip weather strip 24 is formed, the manufacturing operation becomes easier as compared with the case where the end portion of the drip weather strip 24 is formed separately. Soaring can be suppressed.
[0028]
The present invention is not limited to the configuration of each of the above embodiments, and the structures of the water storage section 31 and the guide section 32 can be further modified.
[0029]
【The invention's effect】
As apparent from the above description, according to the first aspect of the present invention, rainwater or the like that has flowed down to the terminal portion of the drip weather strip is temporarily stored in the water storage portion, and the door lock mechanism of the pillar is opened through the opening. As a result, the water flows down while being guided in a direction avoiding water, so that water can be prevented from entering the door lock mechanism. As a result, it is possible to prevent the occurrence of rust due to water in each component of the door lock mechanism, improve durability, prevent freezing in cold weather, and prevent inconvenience such as a sliding door from being opened. Can be prevented.
[0030]
According to the second aspect of the present invention, it is possible to prevent rainwater and the like from entering the door lock mechanism as in the first aspect of the present invention, and in particular, to guide rainwater and the like more actively away from the door lock mechanism by the guide portion. Can be more reliably prevented from entering the door lock mechanism.
[0031]
According to the third aspect of the present invention, since the water storage portion or the guide portion is formed continuously by extending the terminal portion of the seal portion of the drip weather strip, it can be integrally formed, for example, at the time of molding. Therefore, the manufacturing operation is facilitated, and a rise in cost can be suppressed.
