Description

  The present invention relates to a mounting structure for an automotive glass run in which a glass run having a straight portion and a corner portion for guiding the raising and lowering of a door glass is attached to the inner periphery of a door frame of an automobile door.

As shown in FIG. 5, a glass run 110 for guiding the raising and lowering of the door glass 5 is attached to the inner periphery of the door frame 2 of the door 1 of the automobile.
Conventionally, as shown in FIG. 5, the glass run 110 is attached in the channel 103 of the door frame 2 to guide the raising and lowering of the door glass 5 and to seal between the door glass 5 and the door frame 2. .

  Further, as shown in FIG. 4, the glass run 110 includes an upper side portion of the door frame 2 formed of the straight portion 111 formed by extrusion molding, and a front side vertical side portion and a rear side vertical side portion that are also extruded. These are connected by a corner 112 formed by molding to match the shape of the corner 2b of the door frame 2.

  The seal between the door 1 and the vehicle body is a door weather strip (not shown) attached to the outer periphery of the door panel and door frame 2 and / or an opening trim weather attached to the flange of the opening of the vehicle body. It is made by a strip (not shown).

  As shown in FIG. 6, the straight portion 111 of the main body of the glass run 110 has a substantially U-shaped cross section including a vehicle outer side wall 120, a vehicle inner side wall 130, and a bottom wall 140. A vehicle outer side seal lip 121 is provided so as to extend from the vicinity of the front end of the vehicle outer side wall 120 toward the inside of the main body having a substantially U-shaped cross section. Further, a vehicle inner side seal lip 131 is also provided on the vehicle inner side wall 130 so as to extend from the vicinity of the front end thereof toward the inside having a substantially U-shaped cross section.

The vehicle outer side wall 120, the vehicle inner side wall 130 and the bottom wall 140 of the main body of the glass run 110 are inserted into the channel 103 provided in the door frame 2, and at least a part of the outer surface of each wall is pressed against the inner surface of the channel 103. The glass run 110 is held.
The door glass 5 slides on the inside of the main body of the glass run 110 with a substantially U-shaped cross section, and both side surfaces of the end portion of the door glass 5 are sealed by the vehicle exterior seal lip 121 and the vehicle interior seal lip 131. (For example, refer to Patent Document 1).

  However, in the press door of a vehicle, in order to fit and fix the channel 103 in the door frame 2, the flanges 2e and 2f at the front ends of the door outer panel 2c and the door inner panel 2d of the door frame 2 are welded. In order to secure the welding allowance, the flange portions 2e and 2f are wide and unpleasant in appearance, and in order to cover the flange portions 2e and 2f, a wide vehicle outer cover lip 123 and a vehicle are provided on the glass run 110, respectively. It was necessary to provide an inner cover lip 133.

  Therefore, it takes time and effort to weld the channel 103 to the flange portions 2e and 2f, and the widths of the channel 103, the flange portions 2e and 2f, the vehicle outer side cover lip 123 and the vehicle inner side cover lip 133 are increased, and the respective weights are increased. This is contrary to the demand for lighter vehicles.

  Therefore, the channel 103 is abolished and the glass run 110 is directly attached to the flange portions 2e and 2f. However, in this case, as the door glass 5 moves up and down, the front end of the door glass 5 pushes up the bottom wall 140 of the glass run 110, and the glass run 110 is deformed or the glass run 110 is shifted upward and looks good. Sealing performance may deteriorate or abnormal noise may occur.

For this reason, as shown in FIG. 7, in the corner portion of the glass run 210, there is a projection formed as a stopper member 241 on the outer surface of the bottom wall 240 so as to contact the door inner panel 2d (for example, patent Reference 2).
However, in this case, since the corner stopper member 241 and the vehicle outer side wall 220, the vehicle inner side wall 230, the vehicle outer side seal lip 221, the vehicle inner side seal lip 231 and the like are molded with the same material, the material hardness is high. It was difficult to prevent the glass run 210 from being deformed or displaced sufficiently.

Also, as shown in FIG. 8, there is a door frame 2 in which a stopper member 360 is attached and the bottom wall 340 of the glass run 310 is held in contact with the stopper member 360 (for example, Patent Document 3). reference.).
However, in this case, since the stopper member 360 manufactured as a separate part is mounted at a plurality of locations on the door frame 2, it takes time and increases the cost. Moreover, the position of the stopper member 360 may be displaced.

1 is a cross-sectional view of the corner portion 12 on the rear side of the glass run 10 along the line AA in FIG. 3, and FIG. 2 shows a straight portion 11 in the vertical side portion of the glass run 10 in FIG. FIG. 3 is a cross-sectional view taken along the line -B, and FIG.
First, the vertical side portion of the straight portion 11 will be described, and then the corner portion 12 will be described.

  As shown in FIG. 2, the cross-sectional shape of the straight line portion 11 of the glass run 10 attached to the upper side portion of the door frame 2 is substantially perpendicular to the bottom wall 40 from the vehicle outer side edge of the bottom wall 40 and the bottom wall 40. Alternatively, from the vehicle outer side wall 20 extending downward (downward in FIG. 2) at a slightly obtuse angle, and the vehicle inner side wall 30 extending downward from the vehicle inner side edge portion of the bottom wall 04 substantially perpendicularly or slightly at an obtuse angle downward. The cross section is formed in a substantially U shape. As will be described later, the vehicle interior side wall 30 is larger than the vehicle exterior side wall 20 and is thick, and the substantially U-shaped cross section is formed in an asymmetric shape with a large vehicle interior.

The main body of the glass run 10 has basically the same substantially U-shaped cross-section in both the portion attached to the upper side portion of the door frame 2 and the portion attached to the vertical side portion.
In the above, the vehicle exterior and vehicle interior refer to the vehicle interior and vehicle interior of the vehicle with the door closed, and the upper and lower directions indicate the vertical direction of the vehicle. Is.

The vehicle outer side wall 20 of the glass run 10 is formed in a substantially plate shape in cross section.
A vehicle outer side seal lip 21 extends from the vicinity of the front end of the vehicle outer side wall 20 toward the inside of the main body having a substantially U-shaped cross section. Further, the vehicle outer side cover lip 23 extends from the front end of the vehicle outer side wall 20 toward the outside of the vehicle outer side wall 20 in the substantially U-shaped cross section, that is, parallel to the vehicle outer side wall 20 in the vehicle outer direction. The vehicle outer side cover lip 23 covers the flange portion 2e at the tip of the door outer panel 2c.

  The vehicle inner side surface of the flange portion 2 e of the door outer panel 2 c of the door frame 2 abuts on the outer surface side of the vehicle outer side wall 20. The vehicle outer side holding lip 24 is formed on the bottom wall 40 side of the outer side surface of the vehicle outer side wall 20, and the vehicle outer side holding lip 24 abuts on the flange portion 2e. For this reason, while being able to latch the vehicle outer side wall 20 to the flange part 2e reliably, between the vehicle outer side wall 20 and the flange part 2e can be sealed.

As described above, the vehicle outer side seal lip 21 extends obliquely inside the vehicle outer side wall 20 toward the inner side of the main body of the glass run 10 having a substantially U-shaped cross section.
When the door glass 5 rises and the upper end of the door glass 5 enters the inside of the upper side of the main body of the glass run 10, the vehicle exterior seal lip 21 and the vehicle interior described later are formed on both surfaces of the upper end of the door glass 5.

Further, the vehicle outer side cover lip 23 extends from the tip of the vehicle outer side wall 20 in parallel to the vehicle outer side wall 20 on the vehicle outer side. Similar to the straight portion 11, the flange portion 2 e at the tip of the door outer panel 2 c is sandwiched between the vehicle outer side wall 20 and the vehicle outer cover lip 23.

A vehicle interior seal lip 31 extends from the front end of the vehicle interior side wall 30 toward the inside of the main body in a substantially U-shaped cross section, and the vehicle interior cover lip 33 extends from the vehicle interior side wall 30 to the vehicle interior side wall 30. Is extended in parallel with the vehicle interior side wall 30 on the outer surface side, that is, the vehicle interior side. The vehicle interior cover lip 33 and the vehicle interior side wall 30 hold the glass run 10 by sandwiching the flange portion 2f at the tip of the door inner panel 2d.
The front end of the door inner panel 2d is provided with a bent portion formed by bending in the opening direction of the flange portion 2f (downward in FIG. 1) near the root of the flange portion 2f.

  Engagement projections 37 are formed on the outer surface of the vehicle interior side wall 30 of the glass run 10 on the upper side of the corner portion 12. As shown in FIG. 1, the engaging convex portion 37 includes a first inclined wall 37 a that protrudes obliquely toward the outside of the substantially U-shaped cross section from the upper side to the lower side of the vehicle, and a lower end of the first inclined wall 37 a. It has the 2nd inclination wall 37b which inclines toward the inner side toward the downward direction. The lower end of the first inclined wall 37a or the upper end of the second inclined wall 37b contacts the upper surface side of the bent portion of the flange portion 2f of the door inner panel 2d.

  When the engagement convex portion 37 is formed on the vehicle interior side wall 30, the vehicle interior side wall 30 is larger than the vehicle exterior side wall 20, so that the degree of freedom of space and shape can be increased. A degree of freedom in shape can be ensured. Furthermore, when the door glass 5 abuts, the engagement convex portion 37 is formed on the vehicle inner side wall 30 that is hard to be deformed compared to the vehicle outer side wall 20, and the vertical length compared to the vehicle outer side wall 20 is increased. Since the engagement convex part 37 is formed in the vehicle interior side wall 30 which can be lengthened, the deformation of the engagement convex part 37 can be suppressed and the glass run 10 can be reliably prevented from coming off from the flange parts 2e and 2f.

Since the engaging convex part 37 has the 1st inclination wall 37a which protrudes diagonally toward the outer surface side toward the downward direction from upper direction, when inserting and attaching the glass run 10 from the downward direction of the flange part 2f, the 1st inclination wall The glass run 10 can be smoothly attached to the guide 37a.
Since the lower end of the first inclined wall 37a or the upper end of the second inclined wall 37b is in contact with the upper surface side of the bent portion of the door inner panel 2d, a force pulling the glass run 10 downward is applied after the glass run 10 is mounted. Since the first inclined wall 37a is inclined obliquely downward, the first inclined wall 37a can be stretched against the tension, and the deformation of the engaging convex portion 37 is prevented, and the engaging convex portion 27 is prevented. Prevents the glass run 10 from coming off in the opening direction of the flange portions 2e and 2f.

The engaging convex portion 37 is formed in a cross-sectional shape by bending a part of the vehicle inner side wall 30 outward, and may be formed thicker than the vehicle inner side wall 30.
Instead of the outer surface of the vehicle inner side wall 30, the engagement convex portion 37 can be similarly formed on the outer surface of the vehicle outer side wall 20, and the engagement convex portion 37 is formed on the outer surfaces of both the vehicle outer side wall 20 and the vehicle inner side wall 30. Can also be formed. When the engaging projections 37 are formed on both, the glass run 10 can hold the stopper member 60 more strongly.

A stopper member 60 is attached to the portion of the glass run 10 where the engaging convex portion 37 on the upper side of the corner portion 12 is formed.
The stopper member 60 is formed in a substantially U-shaped cross section with a predetermined width that can cover the engaging convex portion 37, and is formed of the vehicle outer side wall 61, the vehicle inner side wall 62, and the bottom wall 63. When the stopper member 60 is attached, the vehicle outer side wall 61, the vehicle inner side wall 62, and the bottom wall 63 of the stopper member 60 are brought into contact with the outer surfaces of the glass run 10 and the vehicle inner side wall 30 and the bottom wall 40, respectively. The glass run 10 is held on the outer surface of the main body. For this reason, the outer surface of the vehicle outer side wall 20, the vehicle inner side wall 30, and the bottom wall 40 of the main body of the glass run 10 can be covered with the stopper member 60, and the holding state with the glass run 10 can be obtained stably.

The stopper member 60 has an engagement hole 65 formed in a portion corresponding to the engagement convex portion 37 of the glass run 10. In the present embodiment, since the engagement convex portion 37 is formed on the outer surface of the vehicle interior side wall 30, the engagement hole 65 is formed in the vehicle interior side wall 62. When the stopper member 60 is attached to the glass run 10, the engaging convex portion 37 is fitted into the engaging hole 65. For this reason, the stopper member 60 can be easily attached only by fitting the stopper member 60 into the glass run 10.
When the engagement convex portion 37 is formed on the vehicle outer side wall 20, the engagement hole 65 is formed on the vehicle outer side wall 61 of the stopper member 60.

  When the glass run 10 to which the stopper member 60 is attached in advance is attached to the door frame 2, as shown in FIG. 1, the tip of the stopper member 60 is connected to the flange portion 2e of the door outer panel 2c and the flange portion 2f of the door inner panel 2d. The stopper member 60 is locked by contacting.

  Front end locking portions 64 and 64 that lock the front ends of the flange portions 2e and 2f of the door frame 2 are formed at the front ends of the vehicle outer side wall 61 and the vehicle inner side wall 62 of the stopper member 60, respectively. The front end locking portions 64 and 64 are preferably formed by bending the front ends of the vehicle outer side wall 61 and the vehicle inner side wall 62 to the outer surface side in a U-shaped cross section. In this case, only by inserting the stopper member 60 into the flange portions 2e and 2f of the door frame 2, the front end locking portions 64 and 64 lock the front ends of the flange portions 2e and 2f to ensure the stopper member 60. Can be locked to the flange portions 2e and 2f of the door frame 2, and assembly is easy.

  When the glass run 10 to which the stopper member 60 is attached is mounted on the door frame 2, the vehicle outer side wall 61 and the vehicle inner side wall 62, which are the front ends of both sides of the stopper member 60 having a substantially U-shaped cross section, are the vehicle outer side wall 20 of the glass run 10. Between the vehicle interior side wall 30 and the vehicle interior cover lip 33. Therefore, the vehicle outer side wall 20 and the vehicle outer side cover lip 23 hold the vehicle outer side wall 61 of the stopper member 60 and the flange portion 2e of the door outer panel 2c, and the vehicle inner side wall 30 and the vehicle inner side cover lip 33 hold the stopper member 60. The vehicle interior side wall 62 and the flange portion 2 f of the door inner panel 2 d can be held, and the glass run 10 can be reliably held on the door frame 2.

  Thus, since the stopper member 60 covers the outer surfaces of the vehicle outer side wall 20, the vehicle inner side wall 30, and the bottom wall 40 of the glass run 10, the door glass 5 rises and the bottom wall of the glass run 10 mounted on the upper side portion. 40, the bottom wall 40 is held by the stopper member 60 to prevent the glass run 10 from being deformed, and the engagement convex portion 37 can be fitted into the engagement hole 65 to prevent deformation or displacement. , Appearance and sealability can be ensured.

  The vehicle outer side wall 20, the vehicle inner side wall 30, the bottom wall 40, the vehicle outer side seal lip 21, and the vehicle inner side seal lip 31 of each of the straight portion 11 and the corner portion 12 of the glass run 10 are respectively corresponding portions. It is continuous at the connecting portion between the straight portion 11 and the corner portion 12. For this reason, the vertical side portion and the upper side portion of the glass run 10 can be connected to the respective portions of the corner portion 12 to ensure the sealing performance and sound insulation performance of the connection portion of the corner portion 12.

In the molding of the straight portion 11 of the glass run 10, synthetic rubber and thermoplastic elastomer are used as the molding material. For example, EPDM rubber is used for synthetic rubber, and polyolefin-based elastomer is used for thermoplastic elastomer.
In the case of synthetic rubber, it is conveyed to a vulcanizing tank after extrusion and heated by hot air or high frequency to vulcanize. In the case of a thermoplastic elastomer, it is cooled and solidified. Thereafter, it is cut to a predetermined length to produce an extruded part.

  Next, the molded portion of the corner portion 12 of the glass run 10 is molded by cutting the extruded member produced as described above into a predetermined dimension at a substantially right angle to the longitudinal direction, and the end of the cut extruded portion. The mold forming part is sandwiched between molds to be molded, and a solid material for forming the mold forming part is injected into the cavity of the mold. The cross-sectional shape of the molded part is substantially the same as the cross-sectional shape of the extruded part. It is preferable to use the same type of molding material as that used for the extruded part. In the case of a thermoplastic elastomer, since the injected material is melted when injected into the mold, the extruded part and the molded part are integrally fused by the heat and pressure.

When the straight line portion 11 of the glass run 10 is formed of EPDM rubber, the corner portion 12 of the glass run 10 is preferably formed of EPDM rubber or an olefin-based thermoplastic elastomer. When the straight line portion 11 of the glass run 10 is formed of an olefinic thermoplastic elastomer, the corner portion 12 of the glass run 10 is formed of an olefinic thermoplastic elastomer. In this case, the same kind of material is used, and the adhesion between the straight portion 11 and the corner portion 12 of the glass run 10 is good. In addition, both are olefin-based materials, have good weather resistance, can be pulverized at the same time, and can be easily recycled. In the case of an olefin-based thermoplastic elastomer, vulcanization is not required, and therefore production is easy.
In the case of synthetic rubber, the mold is heated and vulcanized after being poured into the mold. At this time, since the extrusion molding part and the molding part use the same material or the same kind of material, vulcanization adhesion can be performed, and they can be fixed integrally.
