Description

  The present invention relates to a mounting structure for a door weather strip for an automobile that seals between the door of the automobile and the periphery of a vehicle body opening.

  As shown in FIG. 6, the seal between the door 1 of the automobile and the peripheral edge 6 of the vehicle body is a door weather strip 110 attached to the outer periphery of the door frame 2 provided on the outer periphery of the door 1 and / or This is done by an opening weather strip attached to the flange at the periphery 6 of the vehicle body opening. The seal between the door glass 5 and the door 1 is made by a glass run attached to the channel 3 on the inner periphery of the door frame 2.

  Conventionally, as shown in FIG. 7, the door weather strip 110 attached to the outer periphery of the door frame 2 includes an attachment base portion 111, a hollow seal portion 114 and a seal lip portion 116 integrally formed on the upper surface thereof. The The mounting base 111 is fixed to the door frame 2 by being fitted into a U-shaped retainer portion 155 attached to the outer peripheral portion of the door frame 2. When the door is closed, the seal lip 116 contacts the outermost side edge of the vehicle body opening periphery 6 to seal the gap between the outer peripheral edge of the door frame 2 and the vehicle body opening periphery 6. At that time, the hollow seal portion 114 is in contact with the bulging portion on the inner side of the vehicle rather than the portion where the seal lip portion 116 of the vehicle body opening periphery 6 is in contact, and seals between the door 1 and the vehicle body opening periphery 6. ing.

  In recent years, hidden type doors are often used due to design requirements. However, in the hidden type doors, the width of the side edge of the door frame 2 outside the vehicle is narrowed so that the door 1 and the periphery of the opening of the vehicle body In order to narrow the space between the door weather strip 210 and the door weather strip 210, the width of the outer wall 2d of the outer panel 2a of the door frame 2 as shown in FIG. ing.

  For this reason, as a structure for attaching the door weather strip 210, there is a structure in which the exterior molding wall 2d portion of the outer panel 2a of the door frame 2 is reduced and the door molding 250 in which the door molding and the retainer unit are integrated is attached to the door frame 2. is there. In this case, the door weather strip 210 is formed so as to be separated from the outer weather strip 212 and the inner weather strip 213 so that the outer weather strip 212 is made smaller, and the door molding 250 is formed. There is something to install. The sealing portion of the outer weather strip 212 is also formed in a small lip shape as the sealing lip portion 216, and the inner weather strip 213 is lowered and attached to the inner side of the door frame 2. There are some (for example, refer to Patent Document 1).

  In this case, the hollow seal portion 214 of the inside weather strip 213 can be formed in the same size as the conventional one, and the inside frame mounting base 211 is formed by bending the door frame 2 and the door frame retainer portion 2c. The outside weather strip 212 is also made small, and the outside mounting base portion 221 is fitted into a retainer portion 255 formed by bending the door molding 250, and the seal lip portion 216 is fitted to the periphery 6 of the vehicle body opening. It can be abutted and sealed.

However, in the corner portion of the door frame 2, unlike the straight portion, the entire door molding 250 draws a curve. Therefore, it is difficult to form a retainer portion 255 having a C-shaped cross section by bending a part of the door molding 250. . In addition, the outside weather strip 212 is formed so as to protrude toward the front end side in order to cover the front end portion of the door frame 2 at the front end portion of the corner portion of the door frame 2. Therefore, in order to hold the outer weather strip 212 at the tip of the corner portion, the insert member is formed with a locking tool and embedded in the corner portion, or a clip or double-sided adhesive tape is used. However, the mounting is troublesome and the cost is increased, which is not satisfactory and the sealing performance is insufficient (see, for example, Patent Document 2).

That is, a door weather strip 10 is attached to the outer periphery of the door frame 2 to seal between the door 1 and the periphery 6 of the vehicle body opening.
A channel 3 is provided on the inner periphery of the door frame 2, and a glass run (not shown) is attached to the channel 3 to guide the raising and lowering of the door glass 5, and the door glass 5 and the door frame 2. It is sealed between.

  1 to 4 are sectional views of a door weather strip 10 according to an embodiment of the present invention, and FIG. 5 is a rear view of a corner portion 12 of the door weather strip 10 according to an embodiment of the present invention. . 1 to 4 are sectional views of the corner portion 12 of the door weather strip 10 taken along the lines AA, BB, CC, and DD in FIG. 5, respectively. 1 shows a state in which the door weather strip 10 is mounted on the outer peripheral portion of the door 1 of the automobile.

  As shown in FIGS. 5 and 6, the door weather strip 10 has a linear portion 11 corresponding to the upper side portion and the vertical side portion formed into a long shape by extrusion molding, and corresponds to a corner portion of the door frame 2. The corner portion 12 is formed by molding by connecting straight portions. First, the mounting structure of the straight portion of the door weather strip 10 will be described with reference to FIG. 4, and then the mounting structure of the corner portion 12 will be described with reference to FIGS. 1 to 3 and 5.

The straight portion 11 of the door weather strip 10 according to the embodiment of the present invention is attached to the door frame 2 and the door molding 50 as shown in FIG. 4 is a cross-sectional view taken along the line DD of FIG.
In the present invention, the door frame 2 to which the door weather strip 10 is attached is of a so-called hidden type. As shown in FIG. 4, the hidden door frame 2 has a narrow width at the front end of the vehicle and is covered with a door molding 50 attached to the outer periphery of the door frame 2 so that it cannot be seen from the outside of the vehicle. Yes. In the present embodiment, the door molding 50 is formed continuously from the molding part 53 and the retainer part 52. The molding part 53 and the retainer part 52 may be formed separately.
The door molding 50 is fixed to the door frame 2 with clips, screws, or the like.

  The molding part 53 has a predetermined width so as to cover the front end of the door frame 2, and the lower end is bent into a hairpin shape. A glass run (not shown) is sandwiched and held between the portion bent into the hair pin shape and the inner surface of the door frame 2. For this reason, the front end of the door frame 2 can be covered with the molding part 53 so as not to be visible from the outside of the vehicle, and since the molding part 53 holds the glass run, the side wall of the door frame 2 can be deleted. Weight can be reduced.

  Similarly, the upper end of the molding part 53 is bent in the form of a hairpin on the back side and continues to the retainer part 52. The molding part 53 and the retainer part 52 can be formed by bending a sheet metal such as stainless steel. For this reason, as described above, since the molding 53 serves as a decoration for the vehicle outer side standing wall 2d of the door frame 2, the vehicle side standing wall 2d of the door frame 2 can be eliminated, and the weight of the door frame 2 can be reduced. . Further, the retainer portion 52 is provided with spring elasticity so that the vehicle outer side mounting base portion 21 is securely held. Moreover, since it can manufacture by bending a sheet metal, manufacture of the door molding 50 is easy.

The retainer portion 52 is formed in a wide U-shaped cross-sectional shape with a widened bottom. The front end portion of the retainer portion 52 on the vehicle inner side is bent in a hairpin shape, and the vehicle outer side end portion of the retainer portion 52 forms a recess. For this reason, the vehicle exterior mounting base 21 of the vehicle exterior weather strip 20 described later can be held in the recess of the retainer portion 52.
The vehicle outer side portion of the retainer portion 52 is formed continuously with the upper end of the molding portion 53 on the back side of the molding portion 53.

  The inner periphery of the vehicle interior of the door frame 2 is formed at a lower position on the vehicle interior side than the vehicle exterior to which the retainer portion 52 is attached, so that the vehicle interior attachment base 31 of the vehicle interior weather strip 30 described later can be attached. A groove-like door frame retainer portion 2c is formed. The door frame retainer portion 2 c is formed by bending the inner panel 2 b of the door frame 2. For this reason, the vehicle interior weather strip 30 can be attached to a lower position than the vehicle exterior weather strip 20.

As shown in FIG. 4, the door weather strip 10 includes an outside weather strip 20, an inside weather strip 30, and a connecting portion that integrally connects the outside weather strip 20 and the inside weather strip 30. 40.
The outside weather strip 20 is attached to the outside of the outer periphery of the door frame 2, that is, to the retainer portion 52 described above, and seals the front end portion on the outside of the vehicle between the door frame 2 and the vehicle body opening peripheral edge 6.

  The inside weather strip 30 is attached to the inside of the outer periphery of the door frame 2, that is, to the door frame retainer portion 2 c described above, and seals the inside of the vehicle between the door frame 2 and the vehicle body opening peripheral edge 6. The vehicle interior weatherstrip 30 includes a vehicle interior attachment base 31 that is attached to the door frame retainer portion 2c, and a vehicle interior seal portion 32 that contacts and seals the vehicle interior portion of the vehicle body opening periphery 6. For this reason, double sealing can be performed by the above-described outside weather strip 20 and the inside weather strip 30.

The vehicle inner side mounting base 31 is formed in a substantially plate shape, and both side ends thereof are fitted into the door frame retainer portion 2 c of the door frame 2 to hold the vehicle inner weather strip 30. The vehicle inner side attachment base core part 31b in the center part of the vehicle inner side attachment base 31 is formed of a hard material. For this reason, the door weather strip 10 can be prevented from meandering during extrusion molding and vulcanization, and the door frame retainer portion 2c is securely held. Further, when the door weather strip 10 is attached to the door frame 2, the door weather strip 10 can be prevented from extending in the longitudinal direction.
A double-sided adhesive tape may be attached to the back surface of the vehicle interior attachment base 31 and adhered to the door frame 2. In this case, it is not necessary to form the door frame retainer portion 2c of the door frame 2, and the door frame 2 can be easily manufactured.

The vehicle interior seal portion 32 is formed in a hollow shape, and abuts against a bulge portion on the vehicle interior side of the vehicle body opening periphery 6 when the door is closed, so that the space between the vehicle body opening periphery 6 and the door frame 2 can be sealed. .
The vehicle interior seal portion 32 can also be formed in a lip shape.
Further, the door frame retainer portion 2c of the door frame 2 is formed below the portion of the door frame 2 to which the retainer portion 52 is attached. The gap between the peripheral edge 6 and the door frame 2 can be reduced.

As shown in FIG. 4, the vehicle exterior weather strip 20 is formed of a vehicle exterior mounting base portion 21 and a vehicle exterior seal portion 22. The vehicle exterior mounting base 21 is formed in a plate shape with a recessed bottom surface. The bottom surfaces of the vehicle inner side and the vehicle outer side end abut against the retainer portion 52, and the vehicle outer side end is fitted into the recess of the retainer portion 52 as described above.
It is also possible to attach a double-sided adhesive tape to the back surface of the vehicle exterior attachment base portion 21 and adhere it to the retainer portion 52. In this case, the retainer portion 52 of the door molding 50 can be formed in a planar manner, and the door frame 2 can be easily manufactured.

The vehicle exterior seal portion 22 forms a lip-shaped seal portion. A lip-shaped vehicle exterior seal portion 22 is extended from the vehicle exterior mounting base portion 21 of the vehicle exterior weather strip 20 toward the vehicle exterior opening peripheral edge 6 toward the front end portion of the vehicle exterior.
When the door is closed, the vehicle outer side seal portion 22 can close the gap between the vehicle body opening peripheral edge 6 and the front end of the door molding 50. Since the vehicle outer side seal part 22 is a lip shape, it is easy to bend and can reduce door closing force.
In addition, the cross section of the vehicle exterior seal portion 22 can be L-shaped or T-shaped. In this case, the gap between the vehicle body opening peripheral edge 6 and the front end of the door molding 50 can be more reliably closed with the L-shaped or T-shaped bottom with the L-shaped or T-shaped bottom.

  The vehicle exterior mounting base 21 and the vehicle interior mounting base 31 have a base portion or a central portion formed with a vehicle exterior mounting base core 21b and a vehicle interior mounting base core 31b, and the vehicle exterior mounting base core 21b is rigid. It can be formed of the material. When formed of a hard material, it can be firmly held by the retainer portion 52, the vehicle outer side seal portion 22 can be brought into contact with a predetermined position, and sealing performance can be ensured.

As the hard material, the vehicle outer side mounting base core portion 21b of the vehicle outer side mounting base portion 21b can use the same material as the vehicle inner side mounting base core portion 31b of the vehicle inner side mounting base portion 31, for example, a JIS hardness of 85 °. It can be formed from a hard rubber of ~ 95 °. If hard rubber is used, it can be molded simultaneously with other parts using soft rubber.
When the hard material portion is formed of a solid material of EPDM rubber or olefin-based thermoplastic elastomer, a product having good weather resistance can be obtained.

  The surfaces of the vehicle exterior mounting base 21 and the vehicle interior mounting base 31 can be covered with a sponge member. In this case, even if the retainer portion 52 and the surface of the door frame retainer portion 2c are uneven due to attachment holes or the like, the surface layer portions of the vehicle outer attachment base 21 and the vehicle inner attachment base 31 are formed on the retainer portion 52 according to the unevenness. It can adhere | attach and can improve a sealing performance. As this sponge material, an EPDM rubber or an olefin-based thermoplastic elastomer foamed can be used.

  In the door weather strip 10, portions other than those formed of a hard material, that is, both the outside seal portion 22, both the inside seal portion 32 and the inside mounting base portion 31 of the inside weather strip 30, which will be described later, and the connection. The portion 40 is formed of a sponge material of EPDM rubber or olefin-based thermoplastic elastomer. When the hard material is formed of EPDM or an olefinic thermoplastic elastomer, the door weather strip 10 is entirely olefinic and can be used after being crushed together and recycled.

  Next, the corner portion 12 of the door weather strip 10 will be described by taking the corner portion 12 on the rear side of the rear door as an example. 1 is a cross-sectional view taken along the line AA in FIG. 5 of the central portion of the corner portion 12, and FIG. 2 is a BB line in FIG. 5 at a portion near the vertical side portion of the corner portion 12. FIG. 3 is a cross-sectional view taken along line CC in FIG.

  As shown in FIG. 1, the vehicle interior weather strip 30 is formed of a vehicle interior mounting base 31 and a vehicle interior seal portion 32 at the center of the corner portion 12. The vehicle interior attachment base 31 is attached to the door frame retainer portion 2c, and a core take-out hole 33 for taking out the core at the time of molding is formed at the center. The vehicle interior seal portion 32 contacts and seals the vehicle body opening periphery 6 when the door is closed, and the portion of the vehicle exterior weather strip 20 close to the vehicle interior mounting base 31 contacts the back surface of the outer panel 2a of the door frame 2. The vehicle interior seal portion 32 and the vehicle exterior weather strip 20 are held in contact with each other.

Unlike the straight line portion 11, the vehicle exterior weather strip 20 does not have the connecting portion 40, extends directly from the vehicle interior seal portion 32, and is formed from the vehicle exterior mounting base portion 21 and the vehicle exterior seal portion 22. An insert member 23 is embedded in the vehicle outer side mounting base 21. The insert member 23 is embedded so as to extend integrally in the longitudinal direction from the vicinity of the upper side of the corner 12 to the vicinity of the vertical side in FIG.

As shown in FIG. 5, the vehicle outer side mounting base rib 24 is formed at the side end of the corner portion 12 along the bend of the corner portion 12. The insert member 23 is extended to the vicinity of the front end inside the outside mounting base rib 24. For this reason, when the exterior weather strip 20 of the corner portion 12 is attached to the door frame 2, as shown in FIG. The base rib 24 is locked, and the outside weather strip 20 does not leave the door frame 2.

  A vehicle exterior seal portion 22 extends from the surface of the base portion of the vehicle exterior mounting base rib 24 in the direction of the vehicle body opening peripheral edge 6. The vehicle outer side seal portion 22 is formed in a lip shape, and the front end portion 26 abuts on the vehicle body opening peripheral edge 6 when the door is closed. For this reason, it is possible to reliably seal the outermost gap portion between the door 1 and the vehicle body opening peripheral edge 6 and to double seal together with the aforementioned vehicle inner side seal portion 32. Since the vehicle outer side attachment base rib 24 is securely held by the molding bent portion 51, the vehicle outer side seal portion 22 can be reliably sealed without being deformed or bent when the door is closed.

  A vehicle outer attachment base recess 28 can be provided at the root portion between the vehicle outer attachment base rib 24 and the vehicle outer seal portion 26. In this case, the tip end of the molding bent portion 51 engages with the vehicle exterior mounting base recess 28. For this reason, when the corner portion 12 of the outer weather strip 20 is attached to the corner portion of the door frame 2, the side end of the corner portion 12 of the outer weather strip 20 is not detached or displaced. The base of the base rib 24 can be reliably held.

Next, a portion near the vertical side portion of the corner portion 12 will be described with reference to FIG.
The door weather strip 10 at a portion close to the vertical side portion is formed of the vehicle-side weather strip 20 and the vehicle-side weather strip 30 in the same manner as the center portion of the corner portion 12. The shape of the vehicle interior weather strip 30 is substantially the same as the central portion of the corner portion 12, and includes a vehicle interior mounting base 31 and a vehicle interior seal portion 32. The vehicle interior attachment base 31 is fitted into the door frame retainer portion 2c.
The vehicle interior mounting base 31 can be attached to the door frame 2 with a double-sided adhesive tape. Even in this case, the vehicle outer side mounting base portion 21 can be reliably fixed at the corner portion 12.

The exterior weather strip 20 includes an exterior mounting base portion 21 and an exterior seal portion 22.
The insert member 23 is embedded over a part of the vehicle inner side seal portion 32 and a part of the vehicle outer side attachment base portion 21. A clip portion 25 is formed integrally with the insert member 23. As shown in FIG. 5, the clip portion 25 is formed at two locations, and the clip portion 25 is inserted into the reinforcing member 60 attached to the tip of the door frame 2, and the insert member 23 is fixed, whereby the door weather is secured. The corner 12 of the strip 10 is fixed.
