Description

The present invention relates to a vehicle door sealing structure, particularly for vehicle door sealing with an inside weather strip mounted on a door trim facing a door waist opening in a vehicle door and at least the front or rear end is abutted against the door sash. Regarding the structure.

As a sealing structure for a vehicle door by this kind of inside weather strip, for example, the one described in Patent Document 1 has been proposed. The inside weather strip may be referred to as an inner weather strip for the door waist, a waist inner seal, a beltline weather strip, a door waist inside seal member, or the like, paying attention to the mounting position on the vehicle door. ..

In the vehicle door seal structure described in Patent Document 1, the rear vertical side portion of the door glass run (door glass run) mounted on the door sash (glass run channel) and the door waist portion (belt line position). It is a seal structure that focuses on the abutting part of the inner weather strip attached to the flange, and is the part of the inner weather strip that abuts on the rear vertical side of the door glass run, and also has the top wall lip. A web-like end face wall is formed between the upper seal lip and the end face wall so as to be pressed against one of the holding lips of the door glass run.

In the vehicle door seal structure described in Patent Document 1, a gap is unlikely to occur between the inner weather strip and the door sash and the door trim, and it is effective for external noise that has entered the inside of the door to enter the vehicle interior. It is said that it can be prevented. The external noise here refers to, for example, road noise during traveling, wind noise, and the like.

Further, Patent Document 1 discloses that the inner weather strip is attached to the upper edge flange of the door inner panel, but instead of this, the inner weather strip is attached to the trim flange portion of the door trim. Is disclosed in Patent Document 2.

Japanese Unexamined Patent Publication No. 2017-144990 Japanese Patent No. 5946661

However, since the seal structure of the vehicle door described in Patent Document 1 is premised on a structure in which the inner weather strip is attached to the upper edge flange (waist flange portion) of the door inner panel, for example, it is described in Patent Document 2. There is still room for improvement when trying to apply the inner weather strip to the type that is attached to the trim flange portion of the door trim.

Specifically, for example, as described in Patent Document 2, the trim flange portion of the door trim faces the door waist opening, and the inside weather strip (inner weather strip) is attached to the trim flange portion. If this is the case, there will inevitably be a gap between the waist flange portion on the door inner panel side forming the door waist opening and the trim flange portion of the door trim.

Therefore, as in the seal structure described in Patent Document 1, the gap between the waist flange portion and the trim flange portion is simply formed by forming a web-shaped end face wall between the top wall lip and the upper seal lip. It is not possible to block the intrusion route of external noise caused by the above, and there is a risk that external noise will still invade the vehicle interior.

The present invention has been made by paying attention to such a problem, and provides a seal structure for a vehicle door by an inside weather strip that can further suppress the intrusion of external noise into the vehicle interior. be.

INDUSTRIAL APPLICABILITY The present invention is attached to a door trim facing a door waist opening while being close to the waist flange portion of a door panel among vehicle doors, and is in sliding contact with an elevating door glass, and is among the front end and the rear end in the longitudinal direction. A vehicle door seal structure with an inside weather strip whose one end is at least abutted against the door sash.

The inside weather strip includes a base portion extending in the front-rear direction of the door trim, at least two upper and lower glass seal lips protruding from the base portion toward the door glass side, and the base portion. It is composed of a panel seal lip that is formed so as to project from the lower end in the direction opposite to the upper and lower two-stage glass seal lips and abuts on the waist flange portion, and the inside weather strip is formed at one end of the inside weather strip. The shielding lip is integrally projected.

Then, the shielding lip hits at least the door sash while connecting the tip surface of the lower glass seal lip and the tip surface of the panel seal lip of the one end of the inside weather strip. It is characterized in that it is formed as a highly flexible one that bends and deforms in accordance with the door sash when it comes into contact with the door sash.

In this case, it is naturally possible that the shielding lip not only abuts on the door sash but also partly abuts on the door glass run held by the door sash.

As a more desirable aspect for improving the sound insulation effect, the shielding lip is a space formed so as to be separated from the door sash, the waist flange portion of the door panel adjacent thereto, and the door trim in the plan view of one end portion. It is designed to bend and deform so as to fill the space.

As a more specific embodiment of the shielding lip, at the one end of the inside weather strip, the tip surface of one of the lower glass seal lip and the panel seal lip is more than the other tip surface. The shield that protrudes in the same direction as the one end and is inclined uphill toward the same direction as the one end so as to connect the two tip surfaces having different positions in the front-rear direction. The lip is formed.

As a more specific desirable embodiment, the terminal seal member is integrally projected from one end of the inside weather strip, and the terminal seal member has a deformable deep dish shape and is easily deformed and deformed. The shield lip is formed of an upper shield lip and a lower lip support portion of the shield lip, and the lip support portion has a sharpened shape that tapers toward the lower side and one end side. Is formed as.

Similarly, as a more specific desirable embodiment, the tip of the one end side of the lip support portion is biased toward the panel seal lip side from the lower glass seal lip side, and the lip support portion is supported. Of the outer peripheral surface of the portion, the portion connecting the tip on the one end side and the lower glass seal lip is a concave portion.

Similarly, as a more specific desirable embodiment, a partition-shaped reinforcing rib is formed in the central portion of the inner bottom surface of the shielding lip so as to straddle the tip surface of the base portion.

Therefore, in the present invention, since the shielding lip is formed so as to connect the tip surfaces of the lower glass seal lip and the panel seal lip whose protruding directions are opposite to each other, the shielding lip against the door sash is formed. A wide contact area of the lip can be secured, and the intrusion path of external noise caused by the gap between the waist flange portion and the trim flange portion can be blocked.

According to the present invention, at one end of the inside weather strip, a shielding lip is formed so as to straddle the lower glass seal lip and the panel seal lip whose protruding directions are opposite to each other, so that the shielding lip against the door sash is formed. A wide contact area of the lip can be secured. Therefore, the effect of blocking the intrusion route of external noise is improved, the intrusion of external noise into the vehicle interior can be further suppressed, and the quietness of the vehicle interior can be further improved.

Further, a door weather strip 9 having a hollow rubber string shape is attached in a closed loop shape to the peripheral portion of the door 1 including the door body 3 and the door sash 4 on the indoor side. Then, as is well known, when the door is closed, the door weather strip 9 comes into contact with the peripheral edge of the door opening on the vehicle body side, so that the inside and outside of the vehicle are sealed. As a result, airtightness, watertightness, sound insulation and the like are ensured.

FIG. 2 is an enlarged cross-sectional arrow view taken along the line AA of FIG. 1, and shows only the elements on the indoor side of the door glass 6. FIG. 3 is an enlarged plan view of FIG. 2 and shows a view of the door trim 8 in a fluoroscopic state. Therefore, the door glass 6 is not shown in FIGS. 2 and 3. Further, FIG. 4 shows a perspective view seen from the B direction of FIG. 2 after removing the vertical side portion 4b on the rear side of the door sash 4 shown in FIG.

In addition to FIG. 1, as shown in FIGS. Is integrally formed, and is inseparably and integrally fixed to the door body 3 by welding or the like at a portion below the door waist opening 2 shown in FIG. The door glass run 11 is fitted and held in the glass run receiving portion 10b.

The door glass run 11 is formed of, for example, EPDM or other resin-based or rubber-based elastic body, has a substantially U-shaped cross section, and has a pair of left and right seal lips 11a and 11b protruding inward from the opening edge thereof. Has been done. Then, the door glass 6 is received between the pair of seal lips 11a and 11b.

In the door waist opening 2 shown in FIG. 1, as shown in FIGS. 2 and 3, the waist flange portion 12a on the door inner panel 12 side forming the door waist opening 2 is formed upright. The end flange portion 8a on the door trim 8 side is arranged so as to be close to the inside (outdoor side) of the waist flange portion 12a. That is, the end flange portion 8a on the door trim 8 side faces the door waist opening 2. An inside weather strip 13 made of EPDM or other resin-based or rubber-based elastic body is attached to the terminal flange portion 8a of the door trim 8. The terminal flange portion 8a extends over the entire length of the door waist opening 2, whereas the inside weather strip 13 has a vertical side portion 4b and a partition sash 5 on the rear side of the door sash 4 in the door waist opening 2. It is placed between and.

FIG. 5 shows an enlarged cross-sectional shape of the inside weather strip 13 shown in FIG. As shown in FIGS. A panel having two upper and lower glass seal lips 15 and 16 projecting diagonally upward and parallel to each other and a panel projecting from the lower end of the base portion 14 in the opposite direction to the two upper and lower glass seal lips 15 and 16. It is equipped with a seal lip 17. For example, a thin metal plate-shaped core material 18 is embedded in the base portion 14 of the inside weather strip 13, and the inside weather is composed of the base portion 14, the upper and lower two-stage glass seal lips 15, 16 and the panel seal lips 17. The strip 13 is formed by an extrusion molding method so as to have a uniform cross-sectional shape in the longitudinal direction.

In FIGS. 2 and 4, the core material 18 is not shown. Further, although the means for fixing the inside weather strip 13 to the terminal flange portion 8a of the door trim 8 is not shown, the inside weather strip 13 is fixed to the terminal flange portion 8a by a known cut-up claw piece method. In this fixed structure of the cut-up claw piece method, for example, as described in Patent Document 2 described above, a plurality of claw pieces are cut up together with the core material 18 from the base portion 14 in which the core material 18 is embedded. On the other hand, the claw pieces are inserted into the insertion holes on the terminal flange portion 8a side, and then the claw pieces are bent on the back surface side of the terminal flange portion 8a.

The front end of the inside weather strip 13 is abutted against the door glass run 11 fitted and held in the partition sash 5 shown in FIG. 1, while the rear end of the inside weather strip 13 is as shown in FIGS. It is abutted against a part of the door glass run 11 fitted and held in the vertical side portion 4b on the rear side of the door sash 4 and the vertical side portion 4b thereof. Then, the upper and lower two-stage glass seal lips 15 and 16 of the inside weather strip 13 are in contact with the door glass 6 as shown in FIG. 5, and while sliding relative to the door glass 6 during the raising and lowering operation of the door glass 6. The ascending / descending operation is allowed. Further, as shown in FIGS. It has a function to block the gap between the doors.

As shown in FIGS. Even so, the upper and lower two-tiered glass seal lips 15 and 16 are not directly butted. On the other hand, a terminal seal member 19 to be described later is extended from the rear end of the inside weather strip 13 toward the rear side, and the shielding lip 19a of the terminal seal member 19 is a vertical side on the rear side of the door sash 4. It is abutted against the root portion of one of the seal lips 11a of the door glass run 11 fitted and held in the portion 4b and its vertical side portion 4b.

As described above, FIG. 2 is an enlarged cross-sectional arrow view taken along the line AA of FIG. 1, and shows only the elements on the indoor side of the door glass 6. FIG. 3 is a plan view of FIG. 2 and shows a view of the door trim 8 in a fluoroscopic state. Further, FIG. 4 shows a perspective view seen from the B direction of FIG. 2 after removing the vertical side portion 4b on the rear side of the door sash 4 shown in FIG.

As shown in FIGS. 2 to 4, the rear end of the inside weather strip 13 itself is interrupted in front of the vertical side portion 4b on the rear side of the door glass run 11, but the rear end of the inside weather strip 13 itself. The terminal seal member 19 is extended from the door. As will be described later, the terminal seal member 19 is formed of a substantially deformed petal-shaped or deformed deep dish-shaped shielding lip 19a and a lip support portion 19b below the shielding lip 19a. Then, at least the shielding lip 19a is abutted against the root portion of one of the seal lips 11a of the door glass run 11 fitted and held in the vertical side portion 4b on the rear side of the door sash 4 and the vertical side portion 4b thereof. There is.

6 is an enlarged rear view of the rear end portion of the inside weather strip 13 shown in FIGS. 2 to 4 as viewed from the indoor side (the terminal flange portion 8a side of the door trim 8), and FIG. 7 is a plan view of FIG. .. Further, FIG. 8 is a front view seen from the left side of FIG.

As shown in FIGS. 6 to 8 in addition to FIG. 5, the inside weather strip 13 including the base portion 14, the upper and lower two-stage glass seal lips 15, 16 and the panel seal lips 17 is extruded as described above. It is molded into a uniform cross-sectional shape as shown in FIG. 5 in the longitudinal direction by a molding method. Then, as shown in FIG. 6, of the rear end portion (left end of FIG. 6) of the extruded inside weather strip 13, the upper and lower two-stage glass seal lips 15 and 16 are slanted with the inclined cutting line 13a. The base portion 14 is cut diagonally with an inclined cutting line 13b deeper than the cutting line 13a. Further, the panel seal lip 17 is cut at a right angle to the longitudinal direction with a cutting line 13c deeper than the cutting line 13b.

In this way, the terminal portion at the rear end of the inside weather strip 13 cut into a so-called stepped shape is inserted into the mold, and the mold is filled with the resin material to be the terminal sealing member 19 by the mold molding method. The terminal seal member 19 including the shielding lip 19a and the lip support portion 19b below the shielding lip 19a is integrally molded so as to project further rearward from the upper and lower two-stage glass seal lips 15 and 16 of the inside weather strip 13. .. As is clear from FIGS. 6 to 8, in the portion of the upper and lower two-stage glass seal lips 15 and 16 closer to the terminal seal member 19, the tip of the lip gradually approaches the base portion 14 as compared with the other portions. It is gradually changing.

More specifically, as shown in FIGS. 6 to 8, among the rear ends of the inside weather strip 13, the cutting line 13a of the lower glass seal lip 16 and the panel seal lip 17 are cut while bypassing the base portion 14. The terminal seal member 19 including the shielding lip 19a inclined uphill from the cutting line 13c side of the panel seal lip 17 toward the cutting line 13a side of the lower glass seal lip 16 so as to connect to the wire 13c. It is integrally formed by adjusting upwards. Then, as shown in FIGS. 6 and 8, the terminal seal member 19 has a substantially deformed petal-shaped or deformed deep dish-shaped shielding lip 19a, which is a region above the boundary line P1, and a shield lip 19a below the boundary line P1. It is formed of a lip support portion 19b, which is a region and is located deeper than the boundary line P1. Further, the width dimension on the upper surface of the rear end of the shielding lip 19a is formed to be wider than the separation distance between the lip tips (upper end of the lip) of the lower glass seal lip 16 and the panel seal lip 17. As a result, the cutting line 13a of the lower glass seal lip 16 and the cutting line 13c of the panel seal lip 17 shown in FIG. 6 are both joint lines with the terminal seal member 19.

That is, at the rear end of the inside weather strip 13, the rear ends of the glass seal lip 16 and the panel seal lip 17 are held together while including the cross-sectional shapes of the lower glass seal lip 16 and the panel seal lip 17 shown in FIG. A terminal seal member 19 including a shielding lip 19a having a shape curved in a substantially deformed petal shape or a deformed deep dish shape is formed so as to be tied. As shown in FIG. 3, the terminal seal member 19 is intended to abut the main body portion 10a and a part of the door glass run 11 among the vertical side portions 4b on the rear side of the door sash 4, and therefore the main body portion 10a. It has sufficient flexibility so that it can be easily bent and deformed in the same manner as the door glass run 11.

Then, as shown in FIGS. 6 to 8, substantially, on the upper surface side of the shielding lip 19a of the terminal seal member 19, the cutting line 13b of the base portion 14 and the central portion of the inner bottom surface of the shielding lip 19a are straddled. The base portion 14 is extended toward the shielding lip 19a, and the partition wall-shaped reinforcing rib 20 is formed so as to partially overlap the base portion 14. As a result, the cutting line 13b of the base portion 14 shown in FIG. 6 is a joining line with the reinforcing rib 20.

Further, in the lip support portion 19b on the lower side of the shielding lip 19a of the terminal seal member 19, as is clear from FIGS. 6 and 8, the lower end portion of the inside weather strip 13 shown in FIG. 5 (the C portion in FIG. 5). The shape is tapered and sharp so that the width dimension gradually decreases downward in the front view of FIG. 8 so as to converge with the cross-sectional shape of. At the same time, the lip support portion 19b of the terminal seal member 19 has a substantially triangular shape in the rear view of FIG. 6, and as is clear from FIGS. 4 and 6 and 8, the rear end side of the terminal seal member 19 itself. The shape is tapered and sharpened so that the width dimension gradually decreases toward (the left end side in FIG. 6). That is, the lip support portion 19b of the terminal seal member 19 has a shape like a so-called hull bow shape, which has a sharp shape both downward and toward the rear end side.

Then, as shown in FIGS. 4 and 6 and 8, of the lip support portion 19b of the terminal seal member 19, the ridge line P2 at the rearmost end is deviated toward the panel seal lip 17 side from the lower glass seal lip 16 side. Of the outer peripheral surface of the lip support portion 19b, the portion connecting the rearmost ridge line P2 and the lower glass seal lip 16 is a recessed portion 19c that is recessed inward.

As described above, since the reinforcing rib 20 and the lip support portion 19b are attached to the shielding lip 19a which is the main element of the terminal sealing member 19, the flexibility required for the shielding lip 19a itself is excessive or insufficient. It is considered not to be. That is, the reinforcing rib 20 is formed on the inner bottom surface side of the substantially deformed petal-shaped or deformed deep dish-shaped shielding lip 19a of the terminal seal member 19, and the hull tip-shaped lip support portion 19b is formed on the lower surface side of the shielding lip 19a. As a result, the shielding lip 19a of the terminal seal member 19 is provided with appropriate flexibility. However, as is clear from FIGS. 4 and 6, the reinforcing rib 20 and the lip support portion 19b do not extend to the rear end (left end in FIG. 6) of the shielding lip 19a.

Therefore, in such a sealing structure with the inside weather strip 13, as shown in FIG. 1, the door glass 6 is fitted and held in the vertical side portion 4b on the rear side of the door sash 4 and the partition sash 5. It is guided and supported by the door, and can be raised and lowered by operating a wind regulator mechanism (not shown). In this case, the door glass run 11 and the inside weather strip 13 of the door waist opening 2 smoothly allow the door glass 6 to move up and down.

Further, in the closed state of the door glass 6, as shown in FIGS. 11b is pressed against both the front and back surfaces of the door glass 6. At the same time, in addition to the upper and lower two-stage glass seal lips 15 and 16 of the inside weather strip 13, the same upper and lower two-stage glass seals of the outside weather strip (not shown) arranged to face the inside weather strip 13 with the door glass 6 sandwiched between them. The lip is pressed against both the front and back surfaces of the door glass 6. As a result, the inside and outside of the vehicle are sealed with the door glass 6 interposed therebetween, and airtightness, watertightness, sound insulation, and the like are ensured.

On the other hand, when focusing on external noise such as road noise and wind noise that inevitably invaded the inside of the door body 3 as the vehicle traveled, as shown in FIGS. 2 and 3, the rear side of the door sash 4 At the intersection of the vertical side portion 4b of the door trim 8 side and the inside weather strip 13 on the door trim 8 side, the terminal seal member 19 extended from the inside weather strip 13 side thrusts into the main body portion 10a or the like of the rear vertical side portion 4b. It is matched so that a predetermined sealing function can be exhibited.

More specifically, as shown in FIG. 3, which is a plan view of FIG. 2, the terminal seal member 19 extended from the inside weather strip 13 has its shielding lip 19a on the main body portion 10a of the rear vertical side portion 4b. When pressed, it greatly bends and deforms in the vehicle width direction. As a result, a part of the shielding lip 19a is pressed against the base of one of the seal lips 11a of the door glass run 11, and at the same time, the waist flange portion 12a on the door inner panel 12 side close to the terminal flange portion 8a of the door trim 8 is also pressed. It is being pressed.

Therefore, at the intersection of the vertical side portion 4b on the rear side of the door sash 4 and the inside weather strip 13 on the door trim 8 side, between the terminal flange portion 8a of the door trim 8 and the waist flange portion 12a on the door inner panel 12 side. Even if there are gaps between the terminal flange portion 8a and the door sash 4, those gaps are sealed so as to be filled with the shielding lip 19a of the terminal sealing member 19. Therefore, the intrusion route of external noise near the intersection of the inside weather strip 13 at the door waist opening 2 and the vertical side portion 4b on the rear side of the door sash 4 is blocked by the shielding lip 19a of the terminal sealing member 19, and the wind is blocked. It is possible to suppress leakage noise and contribute to the improvement of quietness in the vehicle interior.

Further, for example, even if the assembly of the inside weather strip 13 varies with respect to the terminal flange portion 8a of the door trim 8, the waist flange portion 12a of the door inner panel 12, the inside weather strip 13, and the vertical side portion on the rear side of the door sash 4 Since the shielding lip 19a having a high flexibility is always interposed between the 4b and the 4b, the effect of blocking the intrusion route of external noise is not impaired.

Further, since the terminal seal member 19 that exerts the effect of blocking the intrusion route of external noise is formed to extend from the rear end of the inside weather strip 13, it is not exposed to the occupant's visible position and spoils the appearance. There is no such thing.

Further, as shown in FIGS. 2 and 3 in addition to FIG. 1, when the door trim 8 to which the inside weather strip 13 is preliminarily attached is assembled to the door 1, the end flange portion 8a of the door trim 8 is the door waist opening 2. It is necessary to get over the waist flange portion 12a and position the terminal flange portion 8a on the outdoor side of the waist flange portion 12a. In particular, as is clear from FIG. 3, the rear end portion of the inside weather strip 13 intersecting the vertical side portion 4b on the rear side of the door sash 4 while greatly bending the shielding lip 19a of the terminal sealing member 19. It is necessary to fit it along the vertical side portion 4b on the rear side.

As a countermeasure, a reinforcing rib 20 is formed on the upper surface of the shielding lip 19a of the terminal seal member 19 so as to substantially extend the base portion 14, and a so-called hull bow is formed on the lower surface of the shielding lip 19a. A lip support portion 19b having a shape is formed. Of the shielding lip 19a, the portion connected to these reinforcing ribs 20 and the lip support portion 19b is less likely to bend in the front-rear direction than the rear end portion where the reinforcing rib 20 and the lip support portion 19b are not formed. Therefore, the rear end side of the shielding lip 19a is relatively easy to bend.

Therefore, as shown in FIG. 3, it is fitted and held in the terminal flange portion 8a in the door waist opening 2, the main body portion 10a in the vertical side portion 4b on the rear side of the door sash 4, and further on the vertical side portion 4b on the rear side. A gap between each element is formed by bending and deforming the base of the seal lip 11a of one of the door glass runs 11 so that the shielding lip 19a of the terminal seal member 19 follows them. Can be effectively filled and shielded.

Moreover, the lip support portion 19b below the shielding lip 19a of the terminal seal member 19 has a shape similar to a so-called hull bow shape, and the lower portion of the lip support portion 19b near the glass seal lip 16. Is relatively large and has a recessed shape portion 19c. Therefore, as described above, while bending the shielding lip 19a, the terminal flange portion 8a to which the inside weather strip 13 is pre-mounted in the door trim 8 is made to get over the waist flange portion 12a in the door waist opening 2. It will be convenient in some cases. That is, while bending the shielding lip 19a of the terminal seal member 19 so as to follow the vertical side portion 4b on the rear side of the door sash 4, the inside weather strip is located outside the waist flange portion 12a of the door waist opening 2. 13 can be easily fitted.

As a result, even if the terminal seal member 19 is integrally formed on the inside weather strip 13, the assembling property of the door trim 8 to which the inside weather strip 13 is pre-mounted is not impaired.

Here, in the above embodiment, the inside weather strip 13 provided with the upper and lower two-stage glass seal lips 15 and 16 has been described as an example, but depending on the specifications of the inside weather strip 13, three or more stages of glass may be used. Some are provided with a seal lip, and the present invention can be applied in that case as well.

Further, in the above embodiment, as shown in FIG. 1, among the front doors 1 having the partition sash 5, the intersection of the vertical side portion 4b on the rear side of the door sash 4 and the inside weather strip 13 is taken as an example. As described above, the present invention is not limited to this aspect.
