Description

  The present invention relates to a seal structure for a B-pillarless vehicle door in which a sliding door that moves back and forth is matched to a front door that opens and closes to the left and right.

  As shown in FIG. 4, the front door of the vehicle is a front door 1 that is provided with a hinge on the front side and opens and closes in the left-right direction of the vehicle, similar to a normal door. A slide door 2 of a so-called B pillar-less vehicle, which is a slide door 2 that moves in the front-rear direction and is not provided with a pillar (B pillar) at a position on the body 100 side that faces the mating portion of both doors 1 and 2. It has been known.

In this type of vehicle, a mounting base portion 102 of the body-side weather strip 101 is attached to a flange F formed on an opening peripheral edge on the body 100 side, and a hollow seal that bulges outside the vehicle is attached to the mounting base portion 102. The part 103 is integrally formed.
A front door weather strip 10 is attached to the upper rear corner and the lower rear corner of the front door 1.
Further, a slide door weather strip 20 extending in the vertical direction is attached to the front end of the slide door 2. The weather strip 20 for the sliding door is composed of upper and lower mold forming portions 20A and 20B and an extrusion forming portion 20C therebetween, and a hollow portion 22 is formed integrally with a mounting base portion 21 attached to the sliding door 2.

When the doors 1 and 2 are closed, as shown in FIG. 5, the hollow seal portion 103 of the body-side weather strip 101, the upper and lower mold forming portions 10A and 10B of the front door weather strip 10, and the slide door weather are provided. The upper and lower mold parts 20A and 20B of the strip 20 are elastically contacted, and the upper and lower mold parts 10A and 10B of the weather strip 10 for the front door are hollowly attached to the upper and lower mold parts 20A and 20B of the weather strip 20 for the slide door. The vehicle front side end portion of the portion 22 is elastically contacted. Further, the hollow portion 22 attached to the extrusion molding portion 20 </ b> C of the weather strip 20 for the slide door is in elastic contact with the rear end of the front door 1.
As a result, the mating portions of the doors 1 and 2 are closed and sealed. The slide door 2 is also provided with a weather strip 30 that elastically contacts the end of the front door 1 and closes the parting portion when the doors 1 and 2 are closed.

In the slide door type of the B pillarless vehicle shown in FIGS. 4 and 5, when the front door 1 is closed with the slide door 2 closed, the slide door 2 is closed with the front door 1 closed. There is a case. The approach direction of the front door 1 at that time is indicated by an arrow X, and the approach direction of the slide door 2 is indicated by an arrow Y.
In particular, when the slide door 2 is closed with the front door 1 closed, the upper and lower mold portions 10A and 10B of the front door weather strip 10 are elastically contacted with the hollow seal portion 103 of the body-side weather strip 101. While sealing, it is necessary to insert the vehicle front side end portion of the hollow portion 22 of the weather strip 20 for the sliding door.

  Therefore, the shape of the front end of the hollow portion 22 of the weather strip 20 for the sliding door is wedge-shaped, and the wedge-shaped portion 23 is elastically contacted with the upper and lower mold portions 10A and 10B of the weather strip 10 for the front door. . Moreover, it is necessary to give rigidity by molding the upper and lower mold forming portions 20A and 20B of the weather strip 20 for the slide door with a solid material.

However, if the upper and lower mold forming portions 20A and 20B of the slide door weather strip 20 are formed of a solid material, the rigidity is high. Therefore, when the wedge portion 23 is brought into elastic contact with the upper and lower mold forming portions 10A and 10B of the front door weather strip 10. As shown in FIG. 5, the upper and lower mold parts 10 </ b> A and 10 </ b> B of the front door weather strip 10 and the hollow part of the slide door weather strip 20 are in elastic contact with the hollow seal part 103 of the body-side weather strip 101. A triangular gap P is likely to occur between the 22 wedge-shaped portions 23. In particular, if there is unevenness in building, the triangular gap P is more likely to occur.
As described above, when the triangular gap P is generated, there is a problem that the sealing function is inferior.

  Accordingly, an object of the present invention is to provide a seal structure for a B-pillarless vehicle that prevents a triangular gap from being generated between the front door and the slide door that are elastically contacted via a weather strip and does not deteriorate the sealing function. It is to provide.

To achieve the above object, a seal structure for a B-pillarless vehicle according to claim 1 of the present invention is provided with a hinge on the front side of the vehicle, and the rear end of the front door (1) that opens and closes in the left-right direction of the vehicle. The front end of the slide door (2) that moves in the front-rear direction of the vehicle at the mold forming part (10A, 10B) of the weather strip (10) for the front door and the rear end of the front door (1) respectively attached to the upper and lower corners The weather strip (20) for the sliding door attached to the door is elastically contacted when the front door (1) and the sliding door (2) are closed to block the mating portion of the doors (1, 2), and the doors (1 , not pillar provided at a position of the body (100) side opposite to the mating part of 2), yet the flange formed in the door opening peripheral edge of the body (100) side (F), Bode A mounting base (102) of the side weatherstrip (101) is mounted, and the mounting base (102) has a molded part (10A, 10A) of the weather strip (10) for the front door when both doors (1, 2) are closed. 10B) and a seal structure for a B-pillarless vehicle in which a hollow seal portion (103) elastically contacting the upper and lower mold portions (20A, 20B) of the weather strip for slide door (20) is integrally formed,
While forming the upper and lower mold parts (20A, 20B) of the weather strip for slide door (20) with a sponge material, the tips of the upper and lower mold parts (20A, 20B) are finned,
The portion of the flange (F) located at the mating portion of both doors (1, 2) is movable from a fixed position inside the vehicle toward the outside of the vehicle, and when both doors (1, 2) are not closed, the flange (F) is moved to a fixed position so that the hollow seal portion (103) of the body-side weather strip (101) is replaced with the mold forming portion (10A, 10B) of the front door weather strip (10) and the weather strip for the sliding door ( 20), when both doors (1, 2) are closed, the flange (F) is moved to the outside of the vehicle so that the hollow seal portion (103) of the body side weather strip (101) is used for the front door. The weather strip for sliding doors is brought into elastic contact with the mold forming portion (10A, 10B) of the weather strip (10) and the weather strip for sliding door (20). The fin shape 20), intended to come into close contact with the molded part of the weather for the front door strip (10) (10A, 10B),
The flange (F) is provided in a rack (41) screwed to the pinion (42), and drives the motor (M) connected to the pinion (41) to rotate the pinion (42) forward or backward. By rotating, the part of the flange (F) can be moved .

  In the invention according to claim 2, the upper and lower mold parts (20A, 20B) of the weather strip for slide door (20) according to claim 1 are attached to the slide base (2). The hollow portion (22) is integrally formed, and the front side of the hollow portion (22) in the vehicle has the fin shape.

  Symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and the best mode for carrying out the invention described later.

According to the present invention, when both the front door and the sliding door are not closed, that is, when both the doors are open, or when one of the doors is open, the flange F is disposed inside the vehicle. Since the hollow seal portion of the weather strip for the body side is separated from the mold forming portion of the weather strip for the front door and the weather strip for the slide door, the fin shape portion of the weather strip for the slide door is the front door. The adhesion of the weather strip to the molded part is released, and the fin-shaped part is separated from the molded part of the front door weather strip.
On the other hand, when both the front door and the sliding door are closed, the flange F is moved from the fixed position inside the vehicle to the outside of the vehicle, and the hollow seal portion of the body-side weather strip is replaced with the molding portion of the weather strip for the front door. Since the slide-shaped weather strip is elastically contacted with the slide door weather strip, the fin-shaped portion of the slide door weather strip is brought into close contact with the mold forming portion of the front door weather strip. As a result, the mating portion of both doors is more beautifully blocked than that of the wedge-shaped portion shown in the conventional example, and the occurrence of a triangular gap is prevented.

Therefore, the sealing performance between the molded part of the weather strip for the front door and the weather strip for the slide door is not particularly deteriorated.
In addition, the upper and lower mold parts of the weather strip for sliding doors with fin-shaped parts are thin and made of sponge material. However, there is no problem because the fin-shaped portion is pressed by the hollow seal portion of the moved body-side weather strip.

  A seal structure for a B-pillarless vehicle according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a seal structure for a B-pillarless vehicle according to an embodiment of the present invention, which corresponds to a cross section taken along line BB of FIG. 4, and FIG. 2 shows a seal with its body-side weather strip in a fixed position FIG. 3 shows a structure corresponding to a cross section taken along line AA of FIG. 4, and FIG. 3 shows a seal structure in a state where the body-side weather strip is located outside the vehicle. It is an equivalent figure.

The seal structure of the B-pillarless vehicle according to the embodiment of the present invention is the same as that shown in the conventional example (FIG. 5), the rear of the front door 1 is provided with a hinge on the front side of the vehicle and opens and closes in the left-right direction of the vehicle. Molded portions 10A and 10B of the weather strip 10 for the front door respectively attached to the top and bottom corners, and the slide door attached to the rear end of the front door 1 and the front end of the slide door 2 moving in the front-rear direction of the vehicle The weather strip 20 is elastically contacted when the front door 1 and the slide door 2 are closed, and closes the joint portion of the doors 1 and 2. And the pillar is not provided in the position by the side of the body 100 facing the matching part of both the doors 1 and 2. As shown in FIG. In addition, a mounting base 102 of the body-side weather strip 101 is attached to a flange F formed on the peripheral edge of the opening on the body 100 side, and the weather strip for the front door is attached to the mounting base 102 when both doors 1 and 2 are closed. A hollow seal portion 103 is formed integrally with the 10 mold forming portions 10A and 10B and the upper and lower mold forming portions 20A and 20B of the weather strip 20 for sliding doors.
In addition, the same code | symbol was attached | subjected to the same part as the prior art example.

  The seal structure of the B-pillarless vehicle according to the embodiment of the present invention is different from that shown in the conventional example (FIG. 5) in that the upper and lower mold parts 20A and 20B of the sliding door weatherstrip 20 are replaced with solid materials. The point formed by the sponge material, the tip of the upper and lower mold forming parts 20A, 20B, that is, the front side of the hollow part 22 formed integrally with the mounting base 21 attached to the slide door 2 is changed into a wedge shape and a tapered fin. The point of the shape, the portion of the flange F located at the mating part of the doors 1 and 2, that is, the upper and lower portions of the mating part of the doors 1 and 2, with respect to the body 100 from the fixed position on the inner side The point of making it movable is very different.

The fin-shaped portion 25 has a longer tip than that of the wedge-shaped portion 23 of the conventional example, and can cope with variations in installation.
The flange F is provided at the front end of the rack 41 in a direction perpendicular to the extending direction (moving direction) of the rack 41. A pinion 42 provided on the body 100 side is screwed to the rack 41, and the pinion 42 is rotated by driving a motor M connected to the pinion 42, so that the rack 41 is moved from a fixed position inside the vehicle. It can be moved from the outside of the vehicle to the fixed position inside the vehicle from the outside of the vehicle. By the movement of the rack 41, the body-side weather strip 101 attached to the flange F provided at the tip of the rack 41 can be moved from the inside of the vehicle to the outside of the vehicle or vice versa. In FIG. 4, the movement range is indicated by Z.

Next, an operation when the front door 1 and the sliding door 2 are opened and closed will be described.
When both the front door 1 and the sliding door 2 are not closed, that is, when both the doors 1 and 2 are open, or when one of the doors is open, it is indicated by a solid line in FIG. As described above, the pinion 42 is rotated forward by the drive of the motor M, the rack 41 provided with the flange F is moved to a corresponding position inside the vehicle, and the hollow seal portion 103 of the body-side weather strip 101 is moved. The front door weather strip 10 is separated from the mold forming portions 10 </ b> A and 10 </ b> B and the slide door weather strip 20.
As a result, the fin-shaped portion 25 of the slide strip weather strip 20 is released from the adhesion to the mold forming portions 10A and 10B of the front door weather strip 10, and as shown in FIG. It leaves | separates from the shaping | molding part 10A, 10B of the weather strip 10 for front doors.

When both the front door 1 and the sliding door 2 are closed, the pinion 42 is reversely rotated by driving the motor M as shown by the two-dot chain line in FIG. The rack 41 thus moved is moved from a fixed position inside the vehicle to the outside of the vehicle, and the hollow seal portion 103 of the body-side weather strip 101 is moved to the mold forming portions 10A and 10B of the weather strip 10 for the front door and the weather strip 20 for the slide door. To make it elastic.
As a result, the fin-shaped portion 25 of the slide strip weather strip 20 is brought into close contact with the mold forming portions 10A and 10B of the front door weather strip 10, and as shown in FIG. However, as compared with that of the wedge-shaped portion 23 shown in the conventional example, it is closed more clearly, and the generation of the triangular gap P is prevented.

Therefore, the sealing performance between the molded portions 10A and 10B of the front door weather strip 10 and the slide door weather strip 20 is not particularly deteriorated.
Further, since the upper and lower mold forming portions 20A and 20B of the slide door weather strip 20 on which the fin-shaped portion 25 is formed are thin and formed of a sponge material, the mold forming portions 10A and 10A of the front door weather strip 10 are formed. Although there is a concern about a decrease in rigidity at the time of elastic contact with 10B, there is no problem because the fin-shaped portion 25 is pressed by the hollow seal portion 103 of the body-side weather strip 101 that has been moved.

  In this embodiment, the motor-driven pinion / rack mechanism is used to move the flange F. However, the present invention is not limited to this, and various types such as hydraulic and pneumatic cylinders can be used as long as the flange F is moved. Can be used.
