A door body having a door inner panel, a door outer panel, and a hinge side reinforcement interposed between the panels;
A glass run that is provided above the belt line of the door body and guides the raising and lowering of the door window glass;
The door inner panel and the door outer panel are configured to open to the glass run side between the end portions of the upper projecting portion projecting upward from the belt line, and an opening into which the glass run is fitted.
The hinge side reinforcement includes an engaging portion that is formed in an upper portion interposed between the upper projecting portions and engages the glass run.

  The door structure is light. The opening part into which the glass run is fitted and the engaging part with which the glass run is engaged are configured by a part of the door body, so that the door frame and the lower frame which is different from the conventional door body are made more than the belt line. This is because it does not have to be provided above. That is, as compared with the conventional lower frame, a portion above the belt line of the lower frame can be omitted, and the length of the lower frame can be shortened. By having the engaging portion, the glass run can be positioned without providing the lower frame above the belt line. Further, the door structure has a small number of parts. Since it is not necessary to provide the lower frame above the belt line, it is not necessary to provide a pair of garnishes that cover the exposed portion above the belt line of the lower frame from inside and outside the vehicle in order to improve the appearance. It is.

The door structure 1 according to the first embodiment includes a door body 2 (FIG. 1) and a glass run 3 (FIGS. 2 to 4). The door body 2 includes a door inner panel 21 (FIGS. 3 and 5), a door outer panel 22, and a hinge side reinforcement 23 (FIGS. 3 and 5) interposed between the panels 21 and 22. . The glass run 3 is provided above the belt line 11 of the door body 2 between the door inner panel 21 and the door outer panel 22 and guides the raising and lowering of the door window glass 12. One of the features of the door structure 1 is that the door structure 1 includes a part of the door body 2 and includes an opening 4 into which the glass run 3 is fitted, and an engagement portion 5 with which the glass run 3 is engaged ( FIG. 3). Hereinafter, each configuration will be described in detail.

[Door body]
The door body 2 is provided on the vehicle front side on both the left and right sides of the vehicle, and opens and closes the door opening (FIG. 1). The door main body 2 is a hinge type, and is rotatably fixed to a portion (for example, a front pillar lower) forming a front side edge of the door opening in the vehicle via the hinge (all not shown). FIG. 1 shows a door body 2 on the right front side of the vehicle. The door main body 2 includes a door inner panel 21 (FIGS. 3 and 5) disposed on the vehicle inner side, a door outer panel 22 (FIGS. 1 to 3 and FIG. 5) disposed on the vehicle outer side, and both panels 21 and 22. And a hinge side reinforcement 23 (FIGS. 3 and 5) interposed therebetween.

  Each of the door inner panel 21 and the door outer panel 22 has upper projecting portions 21u and 22u that project upward from the belt line 11 on the front side of the vehicle, and between the upper projecting portions 21u and 22u, It is formed in a hollow shape with a space between them (FIGS. 3 and 5). End portions on the front side of the vehicle in the overhang portions 21u and 22u are fixed to each other (FIG. 5). The end portions 21e, 22e on the rear side of the vehicle in the overhang portions 21u, 22u are spaced from each other to form an opening 4 described later (FIGS. 3 and 5).

  The hinge side reinforcement 23 is attached with a hinge (not shown) for rotatably fixing the door body 2 (FIGS. 3 and 5). The hinge side reinforcement 23 is provided from the upper side to the lower side of the belt line 11 and has an upper part 23u above and a lower part (not shown) below. The upper portion 23u is interposed between the upper overhang portions 21u and 22u. An end portion 23e on the rear side (glass run 3 side) of the upper portion 23u is bent in an L shape (FIGS. 3 to 5).

  A vertical piece 231 of the L-shaped end portion 23e (a piece along the vehicle front-rear direction on the rear side of the vehicle) is fixed to the end portion 21e of the overhang portion 21u (FIGS. 3 and 5). Although this vertical piece 231 may be comprised by the flat plane, the overhang | projection part 232 which protrudes on the door outer panel 22 side and the glass run 3 (holding lip part 35) mentioned later is hooked like this example is formed. It may be. Then, it is difficult for the glass run 3 to come out of the opening 4.

  A horizontal piece 233 of the L-shaped end portion 23e (a piece along the vehicle width direction on the front side of the vehicle) abuts a bottom portion 31 of a glass run 3 described later (FIG. 5). The horizontal piece 233 is provided with a lean force side engaging portion 234 (FIGS. 3 and 4), and the lean force side engaging portion 234 includes a glass run side engaging portion 311 (described later). ) Are engaged. In this example, the lean force side engaging portion 234 is formed of a notch, but may be formed of a through hole or a recessed portion. Alternatively, the lean force side engaging portion 234 may be formed by a convex portion that protrudes toward the glass run side engaging portion 311. In that case, the glass run side engaging portion 311 may be constituted by a notch, a through hole, or a recess.

[Glass run]
The glass run 3 guides the raising and lowering of the door window glass 12 (FIGS. 2 to 5). Examples of the constituent material of the glass run 3 include elastic materials such as rubber. Therefore, rattling of the door window glass 12 can be suppressed. The glass run 3 is provided on the front side and the rear side of the vehicle in the door body 2. Here, the glass run 3 on the front side of the vehicle will be described. Since a known glass run (not shown) on the rear side of the vehicle can be used, description thereof is omitted. The glass run 3 is provided above the belt line 11 and fitted into the opening 4 (FIGS. 3 and 5). The glass run 3 includes a bottom portion 31, a pair of side wall portions 32, a pair of covering lip portions 33, a pair of sliding contact lip portions 34, and a pair of holding lip portions 35 (FIG. 5). These members 31 to 35 are formed in series.

  The bottom 31 is in sliding contact with the end surface of the door window glass 12. The bottom portion 31 includes a portion that contacts the upper portion 23u of the hinge side reinforcement 23 and a glass run side engaging portion 311 that engages with the lean force side engaging portion 234. The glass run side engaging portion 311 is constituted by a convex portion protruding from the outer bottom surface (front surface of the vehicle) of the bottom portion 31 to the outer side (front side of the vehicle), and the lean force side engaging portion 234 (notch ). Thus, positioning of the glass run 3 with respect to the door body 2, particularly positioning in the vertical direction of the vehicle can be performed. The glass run side engaging portion 311 may be constituted by a through hole, a dent, a notch or the like. In that case, the lean force side engaging portion 234 may be constituted by a convex portion.

  Each side wall part 32 is erected from the bottom part 31 toward the opening end side (door window glass 12 side) of the opening part 4. The inner surface of each side wall 32 faces the front side edge of the inner surface (vehicle inner surface) and outer surface (vehicle outer surface) of the door window glass 12, and the outer surface is the end surface 23e of the hinge side reinforcement 23 and the door. At least one of the end portions 21e of the upper overhanging portion 21u of the inner panel 21 and the end portion 22e of the upper overhanging portion 22u of the door outer panel 22 are in contact with each other.

  The covering lip portion 33 is curved outward from the front end of each side wall portion 32, and the end portions 21e and 22e of the upper projecting portions 21u and 22u of the door inner panel 21 and the door outer panel 22 constituting the opening 4 are formed. Cover from the end face to the outside. Thereby, it can suppress that the end surface of the edge parts 21e and 22e of the overhang | projection parts 21u and 22u and the door window glass 12 contact and damage each other. Further, the covering lip portion 33 sandwiches the end portions 21e and 22e of the upper overhang portions 21u and 22u together with the side wall portion 32. Thereby, it can suppress that the glass run 3 fits in the back of the opening part 4 too much.

  Each sliding contact lip 34 seals between the door window glass 12 and the opening 4. Each slidable contact lip 34 is curved inward from the tip of each side wall 32 and slidably contacts the front side edge of the inner surface / outer surface of the door window glass 12.

  Each holding lip 35 holds the glass run 3 in the opening 4. Each holding lip portion 35 is formed so as to protrude outward from the outer surface of each side wall portion 32. In this example, the end portion 22e of the upper overhang portion 22u and the overhang portion 232 of the hinge side reinforcement 23 Are pressed against each other.

[Aperture]
The opening 4 opens to the glass run 3 side (door window glass 12 side) and fits the glass run 3 (FIG. 3). The opening 4 is provided above the belt line 11 and is constituted by a part of the door body 2. Specifically, the opening 4 has an end portion 21e of the overhang portion 21u of the door inner panel 21 and an end portion 22e of the overhang portion 22u of the door outer panel 22 (FIGS. 3 and 5). . Thus, since the opening part 4 is comprised by the door inner panel 21 and the door outer panel 22 which comprise the door main body 2, it is a member (lower frame 6) from the door main body 2 above the belt line 11. FIG. ) Is not necessary. Therefore, the door structure 1 can be reduced in weight. Further, in order to improve the appearance, it is not necessary to provide a pair of garnishes that cover the exposed portion above the belt line 11 of the lower frame 6 from the inside and outside of the vehicle, so the number of parts can be reduced. The opening 4 is provided so as to extend from the belt line 11 to the upper main frame 13 (upper side of the window frame).

[Engagement part]
The engaging part 5 positions the glass run 3. The engaging part 5 is constituted by a part of the door body 2. Specifically, the engagement portion 5 is configured by a lean force side engagement portion 234 formed in the hinge side reinforcement 23. The engaging part 5 is accommodated in the opening part 4, and the glass run side engaging part 311 is engaged. Thereby, the positioning of the glass run 3 with respect to the door body 2, particularly the positioning in the vertical direction of the vehicle can be performed.

[Others]
(Lower frame)
The door structure 1 includes a lower frame 6 that is provided between a door inner panel 21 and a door outer panel 22 below the belt line 11 and guides the raising and lowering of the door window glass 12 (FIGS. 1 and 3). The lower frame 6 is not provided above the belt line 11. The lower frame 6 has an opening 61 that opens to the door window glass 12 side (FIG. 3). As described above, the lower frame 6 can be a lower frame having a cross section formed of a member different from the door main body 2 as in the prior art.

[Function and effect]
The door structure 1 according to the first embodiment is light and has a small number of parts because the opening 4 into which the glass run 3 is fitted and the engaging portion 5 with which the glass run 3 is engaged are configured as a part of the door body 2. Less is. The lower frame 6, which is a separate member from the door body 2, need not be provided above the belt line 11, a portion above the belt line 11 of the lower frame 6 can be omitted, and the length of the lower frame 6 can be shortened. Because. This is because the lower frame 6 does not have to be provided above the belt line 11, and therefore, a pair of garnishes that cover the exposed portion of the lower frame 6 above the belt line 11 from the inside and outside of the vehicle need not be provided. By having the engaging portion 5, the glass run 3 can be positioned without providing the lower frame 6 above the belt line 11.

  The present invention is not limited to these exemplifications, is shown by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
