[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a door pocket structure for an automobile door trim.

[0002]

2. Description of the Related Art FIG. 3 shows a door trim 1 provided in a door panel. The door trim 1 is composed of an upper member 2 having a resin core material surface covered with a skin material, and a lower member made of an injection-molded synthetic resin. The door pocket portion 4 is integrally provided at the center of the lower member 3.

[0003] As shown in FIG. 4, a mounting boss 5 projecting from the inner surface of the door pocket 4 of the lower member 3 is fixed to the upper member 2 via screws 6. The mounting of the lower member 3 is completed.

The bottom surface of the pocket space 7 is formed by a partition rib 8 integrally provided on the inner surface of the door pocket portion 4.

[0005]

As described above, in the conventional door pocket structure, the bottom surface of the pocket space 7 is constituted by the partition ribs 8 provided integrally on the inner surface of the door pocket portion 4. When the width of the partition rib 8 is set wide, it is necessary to set the partition rib 8 long.
Since the tapered die is formed, even if the end of the partition rib 8 is made thinner, it becomes thicker at the root, so that sink occurs. Therefore, the tip of the partition rib 8 must be as thin as possible.

In this case, as shown in FIG. 5, it has been pointed out that a waving phenomenon or a sticky feeling occurs at the tip of the partitioning rib 8, resulting in poor appearance and a reduction in commercial value.

Further, when the tip end of the partitioning rib 8 is set to be thin and tapered, the filling pressure of the resin tends to be set high because the resin filling defect is apt to occur.
Burrs are easily generated in the PL portion, and the work of removing the burrs of the lower member 3 becomes very troublesome.

The present invention has been made in view of such circumstances, and an object of the present invention is to form a lower portion of a door trim by a lower member made of a resin molded body integrally provided with a door pocket portion. In a door pocket structure for an automobile door trim, a door pocket structure for a door trim that does not cause sink marks on a product surface, improves appearance and strength of a bottom surface of the door pocket, and reduces burrs generated on a peripheral portion of an injection molded body. To provide.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a door in an automotive door trim comprising an upper member and a lower member made of a resin molded body integrally provided with a door pocket portion. In the pocket structure, the bottom plate of the door pocket is a pocket plate integrally formed on the inner surface of the door pocket portion,
It is characterized by being divided into an upper member and a body-side plate formed integrally.

[0010]

As is apparent from the above configuration, the bottom plate of the pocket space is divided into a rib-shaped pocket-side plate formed on the inner surface of the door pocket portion and a body-side plate integrally formed with the door trim. The length of the pocket-side plate formed on the inner surface of the door pocket can be made shorter than that of the conventional plate. Will not occur.

Further, even if the thickness of the pocket-side plate is set to a level that does not cause sink marks, the thickness of the tip can be made larger than that of the conventional one even when the die is tapered, and even if the injection pressure is set to be relatively small, resin filling is insufficient. Does not occur. Further, the dimensions of the rib-shaped plate and the mounting boss can be made shorter than in the conventional case, and materials can be saved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a door pocket structure in a door trim according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view showing the structure of a door trim to which the door pocket structure of the present invention is applied, and FIG. 2 is a sectional view showing the door pocket structure according to the present invention.

Referring to FIG. 1, an automobile door trim 10 to which the present invention is applied has an upper member 2 formed by attaching a skin material such as cloth to a surface of a resin core material formed into a required shape.
And a lower member 30 made of a synthetic resin injection-molded and fixed to the lower edge of the upper member 20.

Further, a door pocket 31 is formed at the center of the lower member 30. That is, an opening 32 for a door pocket is formed in the upper edge of the center of the lower member 30, and a pocket-side plate 33, which constitutes a part of a bottom plate of the door pocket 31, is mounted on the inner surface of the door pocket 31. Boss 34 is formed.

On the other hand, at the lower end edge of the upper member 20, a main body side plate 21 is formed to extend downward corresponding to the width of the door pocket portion 31, and the lower side of the main body side plate 21 has a door pocket. The main body side plate 21 is connected to the main body side plate 21 and a mounting flange 22 is extended in the vertical direction.

Accordingly, the door pocket structure according to the present invention is formed on the inner surface of the door pocket portion 31 of the lower member 30 with respect to the mounting flange 22 extending to the main body side plate 21 of the upper member 20, as shown in FIG. When the mounting boss 34 is fixed via the screw 50, the bottom plate of the door pocket is connected to the pocket-side plate 33 formed on the inner surface of the door pocket portion 31 and the upper member 2.
Thus, the length of the pocket-side plate 33 can be reduced to half or less of that of the conventional partitioning rib.

As described above, according to the present invention, the length of the pocket-side plate 33 can be reduced by half.
There is no sink mark on the product surface, and the thickness of the pocket-side plate 33 can be set to be large, the rigidity can be strengthened, the flow characteristics of the resin become good, and the injection pressure is set low. Also, no defective filling occurs.

Furthermore, since the main body side plate 21 can be formed by molding the upper member 20 into a required shape, the number of parts, the number of mounting steps, etc. can be reduced, and the dimensional length of the pocket side plate 33 and the mounting boss 34 can be reduced. This has the effect of reducing cost, for example by reducing the resin material and saving the resin material.

[0020]

As described above, according to the door pocket structure of the vehicle door trim according to the present invention, the following special effects can be obtained.

(1) Since the bottom plate of the door pocket is divided into a pocket-side plate formed from the door pocket and a body-side plate formed integrally with the door trim, the pocket-side plate formed in the door pocket is formed. Since the length can be set to half or less as compared with the conventional partitioning rib, even if the thickness is set to be large so as to prevent the pocket-side plate from waving, sink does not occur on the product surface. Therefore, the appearance of the product surface and the interior of the door pocket are improved, and the appearance and design of the product are improved.

(2) Since the pocket-side plate formed on the inner surface of the door pocket does not need to have a tapered tip, it is possible to improve the resin flow characteristics during injection molding and to set the injection pressure small. There is no filling defect, which suppresses the generation of burrs, and has the effect that the burrs can be easily removed.
