Description
Technical Field
The present invention relates to a glass run channel mounted along a window frame of an opening and closing door for a vehicle, for guiding sliding movement (i.e., lifting) of a window panel (window glass), and for sealing a gap between the window panel and the window frame, and a mounting structure of the glass run channel with respect to the door.
Background
For example, patent document 1 related to "door structure for vehicle" discloses a glass run and its mounting structure as described above in fig. 1 to 3. That is, the window frame 12 integrated with the outer panel 10 of the vehicle door includes an upper frame portion UF, a center pillar portion BP, and a corner portion formed at a crossing position of the upper frame portion and the center pillar portion, and a window frame recess 15 is provided at the corner portion. On the other hand, the glass run 20 includes a main body portion including a side wall portion 212 on the vehicle interior side, a side wall portion 222 on the vehicle exterior side, and a connecting portion 230 connecting the two side wall portions, and an outer lip 225 for supporting the outer panel 10 between the side wall portion 222 and the side wall portion 222 is provided so as to extend in the longitudinal direction of the side wall portion 222 on the vehicle exterior side. The protruding amount (or protruding width) of the vehicle outside lip 225 is substantially the same at a portion facing the upper frame portion and the center pillar portion of the window frame, but protrudes particularly largely outward at a corner portion (a portion bent at a substantially right angle) facing a corner portion of the window frame, forming a glass run channel convex portion 25. When the glass run 20 is attached to (the window frame portion of) the vehicle door, the vehicle outside lip 225 including the glass run protrusion 25 is disposed so as to overlap the outside (the vehicle outside) of the outer panel 10 (see fig. 2). In addition, by fitting the glass run protrusion 25 into the window frame recess 15, an improvement in positioning accuracy of the glass run 20 with respect to the window frame 12 is achieved (see fig. 3 and 1).

Disclosure of Invention
Technical problem to be solved by the invention
However, according to the above-described mounting structure of the glass run, when the vehicle outside lip 225 is mounted on the outside (vehicle outside) of the outer panel 10, there is a concern that: the vehicle exterior lip 225 having the glass run protruding portion 25 formed at the position of the window frame recess 15 provided at the corner of the window frame is recessed toward the vehicle interior. That is, the outside lip 225, particularly the glass run protruding portion 25 that protrudes largely outward, may be more likely to be recessed than other outside lip portions. If a part of the vehicle exterior lip 225 (in this case, the glass run protrusion 25) is recessed toward the vehicle interior, an unexpected gap may occur between the vehicle exterior lip 225 and the garnish (see fig. 2 and garnish 30 of patent document 1) disposed outside the vehicle exterior lip 225. This gap is also not preferable because wind noise is generated during running.
The purpose of the present invention is to prevent a glass run from being partially dented (deformed) at the outer lip portion of a vehicle, when a glass run is mounted to a window frame of a vehicle door, and to avoid as much as possible the occurrence of defects such as wind noise during running.
Means for solving the problems
A first aspect of the present invention is a glass run, characterized in that,
the glass run is an elongated glass run made of an elastic polymer material and is installed along a window frame of a vehicle door having an upper frame, a longitudinal frame, and an inner corner formed between the upper frame and the longitudinal frame, for guiding a sliding movement of a window panel,
the glass run is provided with: an upper edge portion mounted to an upper frame of the window frame; a longitudinal edge portion mounted to a longitudinal frame of the window frame; and a mold forming part connecting the upper edge part and the longitudinal edge part and being mounted at an inner corner part of the window frame,
the glass run is provided with: a base portion facing an end surface of the louver; an inboard side wall portion and an outboard side wall portion that are respectively erected from both widthwise ends of the base portion; and an outside lip protruding from a distal end of the outside side wall portion toward the outside of the vehicle,
the vehicle exterior side lip is provided to extend along the longitudinal direction of the glass run, and when the glass run is attached to the window frame, a part of a door panel of the vehicle door is covered at an upper frame, a longitudinal frame, and an inner corner of the window frame, and a part of a vehicle exterior side portion of the vehicle exterior side lip is covered with a garnish attached to the longitudinal frame of the window frame,
a corner R is formed in the vehicle-outside lip of the mold forming portion,
a thick portion is formed in the vicinity of the corner R on the vehicle-outside lip of the mold forming portion, and the thickness T1 of the thick portion is thicker than the thickness T2 of a portion other than the thick portion in the vehicle-outside lip of the mold forming portion.
According to the first aspect, the rigidity is improved by forming the thick portion in the vehicle-exterior lip of the mold forming portion in the vehicle-exterior lip extending in the longitudinal direction of the glass run channel. Therefore, even when the outer lip of the mold forming portion is placed on the door panel at the upper frame, the vertical frame, and the inner corner portion of the window frame when the glass run is attached to the window frame, the outer lip of the mold forming portion can be prevented from being depressed toward the vehicle interior. This can prevent the occurrence of a gap between the vehicle exterior lip and the garnish covering the vehicle exterior lip from the outside as much as possible, and can prevent or suppress wind noise and the like.
In a second aspect of the present invention, in the glass run according to the first aspect,
the vehicle-outer side lip of the mold forming portion has a fin portion provided near the corner R, and the thick-wall portion is provided in an area of the fin portion.
According to the second aspect, the following effects are obtained in addition to the effects of the first aspect. That is, in the case where the fin portion is provided near the corner R of the mold forming portion, if only the fin portion is provided, the vehicle exterior lip is easily recessed, but by providing the thick portion in the region of the fin portion, the recess of the vehicle exterior lip can be prevented.
In a third aspect of the present invention, in the glass run according to the second aspect,
the corner R is disposed at a location where a first, generally horizontal outboard lip portion, which is connected to and on an extension of the outboard lip of the upper edge portion, intersects a second, generally vertical outboard lip portion, which is connected to and on an extension of the outboard lip of the longitudinal edge portion,
the fin portion is formed such that the first vehicle outside lip portion protrudes further beyond the corner R than the distal end edge of the second vehicle outside lip portion.
A fourth aspect of the present invention is, in the glass run according to any one of the first to third aspects,
the thick portion is formed by filling the vehicle interior back surface with a filler in the vehicle exterior lip of the mold forming portion.
According to the fourth aspect, the following effects are obtained in addition to the effects of the first to third aspects. That is, when the thick portion is formed in the vehicle exterior lip of the mold molding portion, the vehicle exterior surface (the portion that is easily visible from the outside of the vehicle) on the opposite side to the vehicle interior back surface can be maintained in a relatively flat state by filling the vehicle interior back surface (the portion that is not easily visible from the outside of the vehicle), and the appearance (appearance) is not impaired.
A fifth aspect of the present invention is the glass run according to any one of the first to fourth aspects, wherein the thick portion has a thickness distribution as follows: the central region has the greatest thickness, and the thickness gradually decreases from the central region toward the peripheral region.
According to the fifth aspect, the following effects are obtained in addition to the effects of the first to fourth aspects. That is, in the case of forming a mold molding portion connecting an upper side portion and a vertical side portion by injection molding in a glass run, it is generally necessary to consider sink marks that may occur during curing of the resin. In this regard, in the present invention, the thick portion of the vehicle exterior lip of the mold molding portion has a thickness distribution such that the thickness is the thickest in the central region and gradually decreases as going from the central region toward the outer peripheral region, and therefore, the occurrence of sink marks in the thick portion can be suppressed or alleviated.
A sixth aspect of the present invention is the glass run according to any one of the first to fifth aspects,
the corner R is disposed at a location where a first, generally horizontal outboard lip portion, which is connected to and on an extension of the outboard lip of the upper edge portion, intersects a second, generally vertical outboard lip portion, which is connected to and on an extension of the outboard lip of the longitudinal edge portion,
the thick-walled portion is disposed at a position where the first vehicle outside lip portion intersects the second vehicle outside lip portion.
A seventh aspect of the present invention is a structure for attaching a glass run to a door, comprising:
a door panel;
a window frame having an upper frame, a vertical frame, and an inner corner formed between the upper frame and the vertical frame as a frame body for edging a window portion of the door panel;
a glass run, which is the glass run according to any one of the first to sixth aspects, mounted along the window frame for guiding a sliding movement of the window panel; and
a decorative piece mounted to at least a longitudinal frame of the window frame,
in the upper frame, the longitudinal frame and the inner corner portion of the window frame, the vehicle-outside lip of the glass run channel covers a portion of the door panel,
in the vertical frame and the inner corner portion of the window frame, the garnish covers a part of the vehicle-outside lip of the glass run, and the vehicle-outside surface of the vehicle-outside lip of the glass run abuts the garnish over the entire length of the garnish.
According to the seventh aspect, the same effects as those of the first to sixth aspects are achieved. That is, in the glass run used in this mounting structure, since the thick portion is formed in the vehicle-outside lip of the mold forming portion to improve the rigidity, the vehicle-outside lip of the mold forming portion does not sink toward the vehicle interior side even when the vehicle-outside lip is placed on the door panel in the upper frame, the vertical frame, and the inner corner portion of the window frame when the glass run is mounted to the window frame. Therefore, the vehicle-exterior surface of the vehicle-exterior lip of the glass run can be maintained in a state of abutting the garnish without a gap over the entire length of the garnish in the vertical frame and the inner corner portion of the window frame. As a result, a gap between the vehicle exterior lip and the garnish can be avoided, and wind noise and the like can be prevented or suppressed.
Effects of the invention
According to the present invention, when the glass run channel is attached to the window frame of the vehicle door, the occurrence of the recess (deformation) of the vehicle-outside lip portion provided in the glass run channel can be prevented, and the occurrence of the wind noise and other defects during running can be avoided as much as possible.

Detailed Description
An embodiment of the present invention will be described below with reference to the drawings.
Fig. 1 shows a state of a front door 1 as a vehicle door as viewed from the outside of a vehicle. As shown in fig. 1, a window frame 3 is integrally formed with a door panel 2 forming a front door 1. The window frame 3 is a frame body for edging a window portion of the door panel 2, and the window frame 3 includes at least: an upper frame 3a disposed close to a ceiling of the vehicle; a vertical frame 3b disposed along a center pillar that supports a ceiling of the vehicle; and an inner corner 3c (see fig. 2) formed between the upper frame 3a and the vertical frame 3 b. In the door panel 2, in particular, along the window frame 3, a glass run 10 is installed. Further, a decorative member 4 (decorative member) is attached to at least the vertical frame 3b of the window frame 3 so as to cover substantially the entire vertical frame 3b and a part of the glass run 10 from the outside.
The glass run 10 is an elongated member for guiding the sliding movement of the window panel 5, and is mainly made of an elastic polymer material. As the elastic polymer material that can be used, TPE (thermoplastic elastomer) and rubber can be exemplified. In the present embodiment, TPO (olefin thermoplastic elastomer) having a hardness of a80 is used.
As shown in fig. 1 to 3, the glass run 10 includes at least an upper side 11, a vertical side 12, and a mold molding portion 13 as a connecting portion connecting the upper side 11 and the vertical side 12 in the longitudinal direction. The upper edge 11 is mainly attached to the upper frame 3a of the window frame. The vertical side 12 is mainly attached to the vertical frame 3b of the window frame. The upper edge 11 and the vertical edge 12 are each formed in a straight line by extrusion molding.
On the other hand, the mold 13 is mainly a portion to be fitted to the inner corner portion 3c of the window frame, and the mold 13 is formed by injection molding after extrusion molding. Specifically, the distal end portion of the upper side 11 obtained by extrusion molding and the distal end portion of the vertical side 12 are assembled in an injection molding die while intersecting at a predetermined angle (for example, 70 to 90 °) while maintaining a predetermined distance. Then, the elastic polymer material is injected into the molding die and injection molding is performed, thereby forming the die molding portion 13, and thus the overall shape of the glass run 10 is substantially determined. The mold forming portion 13 thus obtained connects the upper side portion 11 and the vertical side portion 12 while maintaining the intersecting arrangement relationship between the upper side portion 11 and the vertical side portion 12.
Next, a basic structure (mainly a cross-sectional structure) common to the upper side 11, the vertical side 12, and the mold forming portion 13 of the glass run 10 will be described with reference to fig. 4 and 5. As shown in these figures, the glass run 10 includes a base portion 14, and an inside side wall portion 15 and an outside side wall portion 16 that are respectively erected from both ends in the width direction of the base portion 14, as viewed in a cross-sectional direction intersecting the longitudinal direction. The base portion 14, the vehicle interior side wall portion 15, and the vehicle exterior side wall portion 16 are each provided to extend along the longitudinal direction of the glass run channel 10. In the present embodiment, the dimension is set such that the vehicle interior side wall portion 15 is relatively long (or high) and the vehicle exterior side wall portion 16 is relatively short (or low). The base portion 14 is also a portion that connects the base end portion of the vehicle interior side wall portion 15 and the base end portion of the vehicle exterior side wall portion 16 to each other and that faces or contacts the end surface of the window panel 5.
For example, as shown in fig. 4, an outer seal lip 21 protruding toward the vehicle interior side is provided at the distal end portion of the vehicle exterior side wall portion 16. The outer seal lip 21 abuts the vehicle outer surface of the louver 5 to seal the end portion of the louver 5. On the other hand, an inner seal lip 22 protruding toward the vehicle outside is provided in the middle of the vehicle inside side wall portion 15. The inner seal lip 22 abuts against the vehicle inner surface of the louver 5 to seal the end of the louver 5. The outer sealing lip 21 and the inner sealing lip 22 are in close proximity to each other and in opposed relationship, and the end of the louver 5 is sandwiched between the two sealing lips.
An inboard lip 23 is provided at a distal end portion of the inboard side wall portion 15, and the inboard lip 23 is formed so as to protrude from the distal end portion toward a side opposite to the inner seal lip 22 (i.e., inboard side) and be folded back along the inboard side wall portion 15. The inboard lip 23 extends along the longitudinal direction of the glass run 10, as in the inboard side wall portion 15. The vehicle interior side lip 23 mainly sandwiches a part of the door panel 2 with the vehicle interior side wall portion 15.
As shown in fig. 4 and 5, an outside lip 24 is provided at the distal end portion of the outside side wall portion 16, and the outside lip 24 is formed so as to protrude from the distal end portion to the side opposite to the outside seal lip 21 (i.e., the outside) and is folded back along the outside side wall portion 16. The vehicle exterior side lip 24 extends along the longitudinal direction of the glass run 10, similarly to the vehicle exterior side wall portion 16. The vehicle exterior side lip 24 also sandwiches a portion of the door panel 2 with the vehicle exterior side wall portion 16. When the glass run 10 is attached to the window frame 3 of the door, the vehicle outside lip 24 covers a part of the door panel 2 in the upper frame 3a, the vertical frame 3b, and the inner corner 3c of the window frame. Further, a part of the vehicle exterior side portion of the vehicle exterior side lip 24 is covered with the garnish 4 attached to the vertical frame 3b of the window frame.
As shown in fig. 3 (and 2), a "corner R" (symbol: 25) is formed in the vehicle-exterior lip 24 of the mold forming portion 13. The corner R25 is an edge or a peripheral edge that is curved into a substantially circular arc-shaped contour near the root of the vehicle exterior lip 24. As shown in fig. 3, the corner R25 is provided at a position where the substantially horizontal outside lip portion 24h intersects with the substantially vertical outside lip portion 24v, the outside lip portion 24h being connected to the outside lip 24 of the upper side portion 11 and being located on an extension thereof (extension thereof toward the left side of the drawing sheet in the drawing), and the outside lip portion 24v being connected to the outside lip 24 of the longitudinal side portion 12 and being located on an extension thereof (extension thereof toward the upper side of the drawing sheet in the drawing). The corner R25 smoothly connects or connects the edge of the substantially horizontal vehicle outside lip portion 24h and the edge of the substantially vertical vehicle outside lip portion 24 v.
In the present embodiment, as shown in fig. 2 and 3, a fin portion 27 is provided near the corner R25 on the vehicle-outside lip 24 of the mold forming portion 13. The fin portion 27 is formed substantially to have a portion protruding in an outward direction from the inner corner portion 3c of the window frame toward the outer corner region. More specifically, as shown in fig. 3, the fin portion 27 is formed so that the substantially horizontal vehicle outside lip portion 24h extends beyond the corner R25 to the left side than the distal end edge of the substantially vertical vehicle outside lip portion 24 v. Therefore, the substantially horizontal upper edge 27a of the fin portion 27 is aligned substantially in a straight line with the distal edge (upper edge in fig. 3) of the substantially horizontal vehicle-outside lip portion 24 h.
In the present embodiment, as shown in fig. 3 and 5, a thick portion 28 is formed in the region of the fin portion 27 in the vehicle-outside lip 24 of the mold forming portion 13. The thick portion 28 is disposed in the vicinity of the corner R25 (right-left position of the corner R in fig. 3).
The thick portion 28 is a portion formed to be thick, particularly, in the vehicle exterior lip 24 of the mold forming portion 13, as described in the text. Further, if the thickness of the thickest part of the thick portion 28 is T1 (see fig. 5) and the thickness of the other parts (non-thick portions) other than the thick portion is T2 (see fig. 4), the thickness will be
T1＝2×T2
The wall thickness is set by way of (a). That is, the maximum wall thickness T1 of the thick-walled portion 28 is set to a thickness of about 2 times the wall thickness T2 of the non-thick-walled portion.
The thick portion 28 is molded simultaneously at the time of injection molding of the mold molding portion 13, but the thickness of the thick portion 28 is ensured by filling the vehicle interior back surface (the surface that can be opposed to the door panel 2) of the vehicle exterior side lip 24 and the vehicle exterior side surface (the side surface that can be opposed to the vehicle interior back surface) at the time of simultaneously molding the thick portion 28. Therefore, the vehicle exterior surface of the vehicle exterior lip 24 of the mold forming portion 13 can be maintained in a relatively flat state without impairing the external appearance.
In addition, when the thick portion 28 formed by filling the vehicle interior back surface of the vehicle exterior lip 24 (or the fin portion 27) is formed as a thickness distribution as follows: the central region has the greatest thickness, and the thickness gradually decreases from the central region toward the peripheral region.
Fig. 6 (a) schematically shows the thickness distribution of the thick-walled portion 28 in the fin portion 27. In fig. 6 (a), the fin portion 27 is seen from the vehicle outside, and therefore the outline of the thick portion 28 is indicated by a thick broken line. The 3 thin broken lines L1, L2, L3 drawn in a similar shape concentric with the thick broken line (outline of the thick portion 28) are contour lines indicating a height (i.e., thickness) protruding from the vehicle interior rear surface. That is, the region surrounded by the broken line L1 is the thickest, and gradually decreases in thickness toward the outer peripheral region as going from l1→l2→l3. In the case of such a thickness distribution, as shown in the envisaged cross section of fig. 6 (B), the variation in thickness at the thick-wall portion 28 is flattened in a mountain shape. In this case, even if the sink mark 31 shown by the phantom line is generated on the side surface opposite to the filler side immediately after the injection molding, the extent of the sink mark 31 is small, and deterioration in the appearance can be suppressed.
Next, a mode of use of the glass run according to the present embodiment will be described.
As shown in fig. 2, 4 and 5, when the glass run channel 10 is attached to the window frame 3, the door panel 2 is engaged between the vehicle interior side lip 23 and the vehicle interior side wall portion 15, and between the vehicle exterior side lip 24 and the vehicle exterior side wall portion 16, whereby the attachment of the glass run channel 10 to the window frame 3 is completed. In this attached state, at least the upper frame 3a, the vertical frame 3b, and the inner corner 3c of the window frame 3 are in a posture in which the vehicle outside lip 24 covers a part of the door panel 2 from above (or from the vehicle outside).
Next, the garnish 4 is attached to the main vertical frame 3b of the window frame 3 to which the glass run 10 is attached. In this attached state, the garnish 4 covers a part of the vehicle outside lip 24 of the glass run in the vertical frame 3b and the inner corner portion 3c of the window frame. At the same time, the vehicle exterior surface of the vehicle exterior lip 24 of the glass run abuts the garnish 4 over the entire length of the garnish 4. In order to achieve or ensure the "contact over the entire length of the garnish", the thick portion 28 provided in the fin portion 27 contributes significantly (the reason will be described later).
In the present embodiment, as shown in fig. 2, the upper edge line 24UL of the vehicle outside lip 24 of the upper edge 11 in the glass run and the line 4UL of the upper edge of the garnish 4 are designed to be substantially horizontally straight. Therefore, the designability around the window frame is excellent.
Unlike the present embodiment, the fin portion 27 is provided in the outer corner region of the mold forming portion 13 of the glass run, and in the case where the thick portion 28 is not provided in the fin portion 27, it is clear that the vehicle exterior lip 24 tends to be recessed toward the vehicle interior side in the region surrounded by the long circular single-dot chain line B in fig. 2 in particular. If this dent is generated, a gap is generated between the vehicle exterior lip 24 and the garnish 4, and this gap causes a problem that wind noise is generated during running.
In this regard, in the present embodiment, since the thick portion 28 is formed in the vehicle exterior lip 24 (i.e., the fin portion 27) of the mold forming portion 13 to increase the rigidity, the vehicle exterior lip 24 of the mold forming portion 13 does not sink inward in the vehicle interior when the vehicle exterior lip 24 is placed on the door panel 2 in the upper frame 3a, the vertical frame 3b, and the inner corner portion 3c of the window frame when the glass run channel 10 is mounted on the window frame 3. Therefore, in the vertical frame 3b and the inner corner 3c of the window frame, the vehicle-outer side surface of the vehicle-outer side lip 24 of the glass run can be maintained in a state of abutting the garnish 4 without a gap over the entire length of the garnish 4. As a result, a gap between the vehicle exterior lip 24 and the garnish 4 can be avoided, and wind noise and the like can be prevented or suppressed.
Modification example
The embodiment of the present invention is not limited to the above embodiment, and can be modified as follows.
In the embodiment of fig. 1 to 6, the fin portion 27 is provided in the outer corner region of the vehicle outside lip 24 of the mold forming portion 13, and the fin portion 27 has a portion protruding in the outward direction, but the portion protruding in the outward direction is not essential to the present invention. For example, as shown in fig. 7, a glass run having no portion protruding in the outward direction can be applied to the present invention also in the outer corner region of the vehicle outside lip 24 of the mold forming portion 13. As shown in fig. 7, in the vehicle exterior lip 24 of the simplified mold forming portion 13, it is clear that a recess tends to be generated in the vehicle interior side at a position slightly below the corner R25 (this position may also be referred to as the vicinity of the corner R). Therefore, by forming the thick portion 28 at a position slightly below the corner R in the vicinity of the corner R, the recess of the vehicle outside lip 24 can be prevented to prevent or suppress wind noise and the like.
