Description

  The present invention relates to a mounting structure for an interior member of a door provided with an interior trim storage portion mounted on the interior side of a door panel of an automobile and a lamp box for illuminating the interior.

Some courtesy lamps mounted on side doors of automobiles have a box for accommodating the lamps attached to the inside of the door. Since the courtesy lamp box is usually made of resin, it is often formed by integral molding with the interior trim of the door made of the same resin.
According to Japanese Patent Laid-Open No. 11-123937 (Patent Document 1), an opening is provided in the center of the inner panel of the door, and a plate panel that closes the opening is attached to the inner panel. When the door is opened in conjunction with the door switch, the board panel is attached with a courtesy lamp box that works to illuminate the feet and to notify the other vehicle that the door is open. An inner trim is attached to the inner panel and its plate panel, and an opening for passing illumination light of the courtesy lamp is provided in the inner trim.
As described above, the box for accommodating the lamp of the courtesy lamp is disposed integrally with the interior trim or attached to another member.
JP-A-11-123937

  However, the courtesy lamp box needs to have a lamp mounting part, wiring holes, etc., and when it is formed integrally with the interior trim, the shape becomes complicated, and the interior is assisted by using a slide type. A trim mold must be formed. On the other hand, various components such as an accessory case are attached to the interior trim, and when the interior trim is molded, the slide mold may not be used in shape. The lamp box is not always necessary, but it is not desirable to omit it because there is a risk of light leakage or water entering the lamp section. In addition, when retrofitting a lamp box of a courtesy lamp, there is a problem that if it is attached with a screw or the like, the installation takes time, and if it is fitted, the mold becomes more complicated.

  The present invention has been made in view of such circumstances, and in the case where the interior trim of the automobile door and the lamp box cannot be integrally formed by a mold, the interior member of the door that can be easily attached to a predetermined location is provided. An object is to provide a mounting structure.

In order to achieve the above object, the present invention provides an interior trim that is mounted on the interior side of a door of an automobile, a pocket-shaped storage section that is formed on the front side by the interior trim, and a wall on the back side of the storage section. In the mounting structure of an interior member of a door, comprising: a back cover that forms a portion; and a lamp box that is disposed on the interior trim and that has an opening side disposed along the interior trim surface, the back cover and the lamp box And a rear cover and a lamp box are attached to the interior trim formed by separate molding.
In the above invention, the back cover and the lamp box are connected by a plate-shaped connecting portion, the connecting portion and the back cover are connected by a reinforcing rib, and the connecting portion and the lamp box are connected by a reinforcing rib. .
Further, in the above invention, the back cover is protruded inward of the door, and the adjacent side surfaces of the lamp box and the back cover are connected by ribs.
Furthermore, in the above invention, a groove for penetrating the connector of the lamp from the box opening edge of the lamp box toward the bottom of the box on the depth side is formed at the same time.

The door interior member mounting structure according to the present invention includes an interior trim that is mounted on the interior side of an automobile door, a pocket-shaped storage portion that is formed on the front side by the interior trim, and a rear wall of the storage portion. In the mounting structure of an interior member of a door, comprising: a back cover that forms a portion; and a lamp box that is disposed on the interior trim and that has an opening side disposed along the interior trim surface, the back cover and the lamp box And a rear cover and a lamp box are attached to the interior trim formed by separate molding. As a result, the lamp box is not integrally molded with the interior trim, which is complicated by the mold by the mold, and the mold shape is integrally molded with a simple back cover, thereby preventing the mold shape from becoming complicated. be able to. For example, by matching the mold release direction of the back cover with the box depth direction of the lamp box, the mold release directions of the both match, and the slide mold can be formed without using it. Therefore, since the lamp box is not molded as a single item, the manufacturing cost can be reduced.
In the above invention, the back cover and the lamp box are connected by a plate-shaped connecting portion, the connecting portion and the back cover are connected by a reinforcing rib, and the connecting portion and the lamp box are connected by a reinforcing rib. Therefore, the connection between the back cover and the connecting portion and the connection between the lamp box and the connecting portion can be reinforced with ribs. Further, since the reinforcing rib becomes a runner, it is difficult to cause defective molding. Since the portion where the rib is formed is on the side of the storage portion of the back cover, even if there is a sink, the appearance is not a problem because it is behind the storage portion.
In the above invention, since the back cover protrudes inward of the door and the adjacent side surfaces of the lamp box and the back cover are connected by ribs, the mounting strength of the lamp box is increased.
In the above invention, the groove for penetrating the connector of the lamp from the box opening edge of the lamp box toward the depth side bottom of the box is simultaneously formed at the time of molding, so that the manufacturing cost can be reduced.

A lamp wiring is routed inside the front door 1, and the wiring is connected to the lamp from the inside of the front door 1 through the opening 28.
A pedestal 23 for attaching a clip 24 for fixing the back cover 6 to the door inner panel 2 a is disposed at a peripheral edge of the back cover 6 in the vicinity of the lamp box 7. It can be positioned and fixed to the highly rigid inner panel 2a.

Next, the function and effect of the embodiment of the present invention will be described.
In the present embodiment, since the back cover 6 and the box 7 are integrally formed, even if the interior trim 3 has a complicated shape, the courtesy lamp box 7 can be attached to the interior trim 3. This is particularly effective when the shape of the interior panel is complicated and a slide mold cannot be used for the formation part of the box 7.
A plurality of ribs 14 to 19 disposed along the peripheral edge of the back cover 6 or in the joint portion 12 are connected to the back cover 6 and the lamp box 7 or the lamp box 7 and the joint portion 12. By forming these ribs 14 to 19, the moldability of the resin as the runner is improved, and the rigidity of the coupling portion is also increased. That is, it is possible to reinforce the connecting portion 12 that is a fixing portion between the back cover 6 and the lamp box 7.

As shown in FIG. 2, a cylindrical storage portion 30 is formed at the front portion of the back cover 6, and a cylindrical storage space such as a plastic bottle along the vertical direction is formed with the back cover 6 assembled. . On the other hand, the lamp box is disposed away from the cylindrical housing portion 30 on the rear side of the vehicle body. As a result, there is little possibility of suffering leakage of the water liquid due to shaking while the vehicle is running.
Further, as shown in FIG. 8, the window regulator 25 is located behind the intermediate position of the front door 1. A deep storage space (width) cannot be formed in the interior trim 3 at a position corresponding to the window regulator 25. Moreover, since it is a position which opposes a seat seat surface, the interior trim 3 cannot overhang largely. Therefore, the cylindrical storage part 30 is arrange | positioned in the front side also using the space more effectively.

By tilting the rear edge portion of the back cover 6 so that the lower side faces forward, the rear portion of the opening 5 of the pocket storage portion 4 and the lamp box 7 are positioned so as to overlap vertically. Accordingly, the overall size of the integrated back cover 6 and lamp box can be kept small while making the opening 5 large so that small articles can be easily taken in and out. Since the inclination of the rear edge part of the back cover 6 is the back side and is not visible, there is no sense of incongruity.
In addition, a clip base 23 for fixing the interior trim 3 to the door inner panel 2a is disposed so as to sandwich the lamp box 7, and the back cover 6 and the interior trim 3 are combined with each other. Can be installed.
