  Conventionally, this problem has been solved by engaging an engaging portion provided on the outer panel side and an engaging portion provided on the belt molding side. The engaging part on the outer panel side is composed of cut and raised pieces and holes (Patent Documents 1 and 2), and the engaging part on the belt molding side is a type provided in the belt molding, a clip coupled to the middle part of the belt molding There are known a type (Patent Document 1) provided on the end member and a type (Patent Document 2) provided on an end member attached to the end of the belt molding. However, none of these are always satisfied from the viewpoints of the simplicity of the structure, the ease of assembly, and the prevention of rotation of the belt molding.

  An object of the present invention is to obtain a belt molding attachment structure that can effectively prevent rotation or drop-off of the belt molding while having a simple structure and easy assembling based on the above problem awareness.

  The present invention has been completed by researching the cross-sectional shapes of the outer panel side and the belt molding side in a belt molding mounting structure in which the engaging portion on the belt molding side is provided in the belt molding body instead of the end member.

The present invention relates to a belt molding mounting structure in which a belt molding having a weather strip that elastically deforms and slides on an elevating glass is attached to an upper edge portion of an outer panel of a vehicle door panel, and the outer panel extends downward from an upper end portion. An extension plate portion and an inwardly inclined plate portion extending obliquely downward from the lower end portion of the lower extension plate portion toward the vehicle interior; the belt molding having a uniform cross section includes a vehicle outer wall portion positioned on the vehicle outer side; Forming a substantially inverted U-shaped cross section having a weather strip and a vehicle interior side wall portion located on the vehicle interior side, and a connection wall portion connecting the vehicle exterior wall portion and the vehicle interior side wall portion; An insertion groove portion into which the inner inclined plate portion is inserted is formed on the inner surface of the vehicle inner wall portion on the door panel side, and the inner inclined plate portion has both a vehicle outer surface and a vehicle inner surface. The insertion groove portion of the belt molding and the inner inclined plate portion of the outer panel are in contact with the inner surface of the insertion groove portion, and the thickness of the distal end portion of the inner inclined plate portion in the cross section perpendicular to the extending direction of the belt molding. Of the inner and outer edges in the direction, the contact portion between the edge on the inlet side of the insertion groove and the inner surface of the insertion groove is A, the contact portion between the edge on the inner side of the insertion groove and the inner surface of the insertion groove is B, When the contact portion between the surface and the upper corner portion of the insertion groove portion is C, the contact portion A is always in linear contact with the contact portion B regardless of variations in the positions of the insertion groove portion and the inward inclined portion. It is characterized by being provided so that either one of C may contact linearly.

  It is practical that the insertion groove is formed by two upper and lower groove-forming ridges formed to protrude toward the door panel side on the door panel side inner surface of the vehicle interior holding portion.

  The amount of protrusion of the two groove-forming protrusions toward the door panel is desirably set such that the protrusion amount of the lower protrusion located below is larger than the protrusion amount of the upper protrusion positioned above.

  The distance between the insertion groove part back side edge of the vehicle inner surface of the lower extension plate part of the door panel and the upper end part of the vertical surface on the door panel side of the upper ridge is an inverted U-shaped cross section from the upper end part of the door panel. It is desirable to set the distance larger than the distance from the inner surface of the belt molding.

  In an aspect in which the upper edge portion of the outer panel has a curved portion, it is preferable that one or more notches be formed on the inner wall portion of the belt molding so as to correspond to the curved portion of the outer panel except for the insertion groove portion.

  The belt molding structure of the present invention has a simple structure (shape) of both the outer panel and the belt molding, is easy to assemble, and can reliably prevent the rotation or dropping of the belt molding.

The inwardly inclined plate portion 13c extends obliquely downward from the lower end portion of the downward extending plate portion 13b toward the vehicle interior (see FIG. 3). 1 and 2 are views of the vehicle door 10 (outer panel 13) as viewed from the inside of the vehicle.

  The belt molding 20 is formed by extrusion molding with a synthetic resin material, and various materials and structures (shapes) are known. 4 to 6 show an embodiment in which the present invention is applied to a belt molding 20 having a two-layer structure including an inner hard resin material 21 and an outer soft resin material 22. The hard resin material 21 includes a vehicle outer wall 21X positioned on the vehicle outer side, a vehicle inner wall 21Y positioned on the vehicle inner side, and a connection wall 21Z connecting the vehicle outer wall 21X and the upper end of the vehicle inner wall 21Y. It has a substantially inverted U-shaped cross section. The soft resin material 22 is composed of a decorative portion 22a that decorates the outer surfaces of the vehicle outer side wall portion 21X and the connecting wall portion 21Z, a lower edge lip 22b that is continuous with the lower end of the decorative portion 22a and elastically deforms and contacts the outer panel 13, window glass 14 (FIG. 4), a weather strip 22 c that contacts the lower side 14, a stabilizer protrusion 22 d below the weather strip 22 c, and an inner lower lip 22 f that protrudes to the inner surface (the surface on the door panel 11 side) of the vehicle outer wall portion 21 </ b> X. The surface of the weather strip 22c and the stabilizer protrusion 22d may be flocked. The soft resin material 22 used for each part may be a different material depending on the part. Various specific examples of these resin materials are known. Specifically, the hard resin material 21 is polypropylene (PP), the decorative portion 22a is TPO (A95 °) (olefinic thermoplastic elastomer), a weather strip 22c, a lower edge lip 22b, a stabilizer protrusion 22d, and an inner lower lip. 22f can be composed of TPO (A65 °). The stabilizer projection 22d can be made of polypropylene (PP). Both TPO (A95 °) and TPO (A65 °) are softer than PP, but TPO (A95 °) is harder than TPO (A65 °). 4 to 6, the weather strip 22c and the inner lower lip 22f depict shapes before the belt molding 20 is attached to the upper edge of the outer panel 13 and elastically deformed.

  On the inner side wall portion 21Y of the hard resin material 21, on its inner surface (the surface on the door panel 11 (outer panel 13) side), an anti-sway projection 23 that contacts the surface of the lower extension plate portion 13b in order from above, an inwardly inclined plate An upper ridge 25 and a lower ridge 26 constituting the insertion groove 24 into which the portion 13c is inserted are formed. The insertion groove portion 24 extends obliquely downward at an angle closer to the horizontal than the downward inclination direction of the inward inclined plate portion 13c, and has a groove lower surface 24a, a groove bottom surface 24b, and a groove upper surface 24c. The upper ridge 25 is connected to the vertical surface 25a on the door panel side by an insertion groove upper corner portion (smooth connection surface) 25b. When the vertical direction surface 21S on the window glass 14 side of the vehicle interior side wall 21Y is used as a reference, the protrusion amount D of the lower protrusion 26 toward the door panel is set larger than the protrusion amount d of the upper protrusion 25 in the same direction. (D> d, FIG. 4).

  A belt molding 20 having an inverted U-shaped cross section having a vehicle outer side wall portion 21X, a vehicle inner side wall portion 21Y, and a connection wall portion 21Z allows the outer panel 13 to enter the reverse U-shaped space, and the inner groove of the outer panel 13 is inserted into the insertion groove portion 24. The distal end portion of the laterally inclined plate portion 13c is inserted to be in a mounted (attached) state on the upper edge of the outer panel 13. In this mounting process, since the protrusion D of the lower protrusion 26 toward the door panel is larger than the protrusion d of the upper protrusion 25 in the same direction, the tip of the inner inclined plate portion 13c of the outer panel 13 is securely inserted. It can be guided into the groove 24.

  FIG. 4 shows an engagement state of the outer panel 13 and the belt molding 20 in the standard state (exactly attached state) of the inwardly inclined plate portion 13c and the insertion groove portion 24. In this exact size state, the inwardly inclined plate portion 13c and the insertion groove portion 24 are in contact with each other at the contact portions A and C in the cross section of FIG. 4 (contacts in a linear shape perpendicular to the paper surface). That is, of the inner and outer edges in the thickness direction of the tip portion of the inwardly inclined plate portion 13c, if the edge on the insertion groove portion entrance side is A and the edge on the back side is B, the inwardly inclined plate portion 13c is the edge A is linearly in contact with the groove lower surface 24 a (inner surface) of the insertion groove 24, and the edge B is not in contact with the groove bottom surface 24 b (inner surface) of the insertion groove 24. On the other hand, the contact portion C is a contact portion between the inner surface of the inwardly inclined plate portion 13c and the inlet portion upper corner portion 25b of the insertion groove portion 24. In this contact portion C, the belt molding 20 and the outer panel 13 are always connected. Contact linearly. In this way, in the standard state (exactly mounted state), the inner inclined plate portion 13c is placed on the inner surface of the insertion groove portion 24 at two locations of the vehicle outer surface (contact portion A) and the vehicle inner surface (contact portion C). By setting the shapes of the inwardly inclined plate portion 13c and the insertion groove portion 24 so that they are not in contact with each other at the contact portion B, the variation in the dimensions of the inner inclined plate portion 13c and the insertion groove portion 24 can be prevented. Even in this case, the inner inclined plate portion 13c can be stably held in the insertion groove portion 24 (the belt molding 20 is attached to the upper edge of the outer panel 13). The contact portion B is a surface on the vehicle outer side of the inwardly inclined plate portion 13c.

  FIG. 3 is a diagram in which variations in dimensions of the inwardly inclined plate portion 13c and the insertion groove portion 24 are drawn together with variations in dimensions of the distal end portion of the inwardly inclined plate portion 13c. The position of the tip of the inwardly inclined plate portion 13c varies within the dotted square in FIG. 5 and 6 are diagrams illustrating the relationship between the inner inclined plate portion 13c and the insertion groove portion 24 when the tip of the inner inclined plate portion 13c is at the point P and at the Q point. When the tip of the inner inclined plate portion 13c is at point P, as shown in FIG. 5, the inner inclined plate portion 13c and the insertion groove portion 24 are linearly contacted at the contact portions A and B, and at the contact portion C, Do not touch. On the other hand, when the tip of the inwardly inclined plate portion 13c is at the point Q, as shown in FIG. 6, the inwardly inclined plate portion 13c and the insertion groove portion 24 are brought into linear contact with the contact portions A and C, and the contact portion No contact with B. The contact portion in FIG. 6 is the same as the contact portion in FIG. 4. However, even if the relative positions of the inwardly inclined plate portion 13 c and the insertion groove portion 24 vary as described above, the contact portion A is always in contact with each other. By bringing any one of the portions B and C into contact, the inner inclined plate portion 13c can be stably held in the insertion groove portion 24 (the belt molding 20 is attached to the upper edge of the outer panel 13).

  Furthermore, in the present embodiment, the upper ridge 25 is on the side of the door panel so that the belt molding 20 does not fall off even when the belt molding 20 receives an inward rotational force (or downward force) about the longitudinal virtual axis. The vertical distance g between the upper end portion of the vertical surface 25a and the edge B on the back side of the distal end portion of the inward inclined plate portion 13c is defined as the upper edge of the outer panel 13 in the exact attachment state of FIG. The distance from the inner surface of the connecting wall 21Z of the belt molding 20 is set larger than the distance f (g> f). If the dimensions are set in this way, even if the belt molding 20 is rotated inward to the maximum (even if it moves downward and becomes f = 0), the tip of the inwardly inclined plate portion 13c is moved upward. 25 is not disengaged from the upper end of the vertical surface 25a (that is, the tip of the inward inclined plate portion 13c does not reach the recess above the upper protrusion 25), and can be easily returned to the exact mounting state. Can be made.

  As shown in FIG. 1, the upper edge of the door panel 11 (outer panel 13) of the present embodiment is smoothly bent upward about 1/3. For this reason, the belt molding 20 is formed with a notch 27 at an interval in the lower part of the inner wall 21 </ b> Y so that it can easily follow the bent shape of the door panel 11. Further, the belt molding 20 has a non-uniform cross section because the portion where the notch 27 exists and the front and rear ends thereof are an end member mounting structure or a structure embedded in the door frame 12. Of course, when the upper edge of the door panel is linear, it is not necessary to provide a notch in the belt molding 20.

  In the above embodiment, the door panel 11 (outer panel 13) has a structure in which one plate is bent. However, in the present invention, as long as the door panel has a downward extension plate portion 13b and an inward inclined plate portion 13c. It doesn't question the structure. For example, FIG. 7 shows a structure in which a reinforcement 15 is sandwiched between one folded outer panel 13.
