Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a pocket structure of an automobile door trim, and more particularly to a pocket structure with improved usability and aesthetics.

<< Description of Prior Art >> As is well known, a pocket for accommodating various kinds of equipment, small items, etc. is provided below the surface of an automobile door trim.

For example, as shown in FIG. 3, a pocket 2 having an open upper portion is attached to the lower side of the surface of a vehicle door trim 1.

And this pocket 2 is generally made of polypropylene, A
An injection molded body of synthetic resin such as BS is used. As shown in FIG. 4, this pocket 2 is provided for a door trim 1 which is a laminated structure of a skin material 3, a pad material 4 and a core material 5.
Are attached by screws 6 from the back surface side of the core material 5.

Further, in the case of the pocket 2 shown in the drawing, which has a relatively deep dimension in the vertical direction, ribs 7 are set in the pocket 2 in order to facilitate the taking out of small items and the like. The inner bottom surface is configured. Further, in order to secure the depth of the pocket, the core material 5 is formed by drawing so as to form a recess.

<< Problems to be Solved by the Invention >> However, since the rib 7 is set on the inner surface side of the pocket 2, appearance defects such as sink marks are conspicuous on the surface side, and aesthetic measures have been urgently needed.

Furthermore, when the core material 5 is draw-formed, the drawing is too shallow, and the drawing accuracy cannot be made constant due to variations, etc., so a gap is created between the two, causing the problem of falling small items, or conversely, strongly. Problems such as excessive hits and deformation have been pointed out.

The present invention has been made in view of the above circumstances, and an object of the present invention is to maintain a beautiful surface appearance of a pocket and to affect the precision of drawing of a core material on the door trim side. It is an object of the present invention to provide a pocket structure for an automobile door trim, which can prevent deformation and is extremely easy to use.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a door trim main body including a core material formed into a required shape, and a skin material integrally coated on the outer periphery of the core material, and a resin. In a pocket structure of an automobile door trim, which comprises a molded body and a pocket body that is attached to an appropriate place on the surface of the door trim body, the core material is drawn into a shape that bulges toward the vehicle interior side, and the bulging portion The bulging portion of the core member constitutes the inner bottom surface of the pocket main body by bringing the tip end portion of the above into contact with the inner wall surface of the pocket main body through the buffer member.

<Operation> According to the above means, the core material on the door trim side is formed into a bulging shape, and the bulging portion constitutes the inner bottom surface of the pocket. It is possible to reliably prevent sink marks on the side.

Furthermore, since the two are brought into contact with each other via the cushioning member between the tip portion of the bulging portion of the core material and the inner wall surface of the pocket, even if there is variation in the drawing accuracy of the molded core material, Variations and the like can be effectively absorbed by the elastic action of the buffer member.

<< Description of Embodiments >> Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an overall perspective view showing a pocket structure of an automobile door trim according to the present invention, and FIG. 2 is a sectional view of the same.

1 and 2, an automobile door trim body 10 according to the present invention includes a board core material 11, a pad material 12 such as urethane foam or polypropylene foam for covering the board core material 11, a PVC sheet, or the like. Skin material 1
It is composed of 3 and 3.

As the board core material 11, a moldable wood fiber board or a composite resin board obtained by mixing a resin such as polypropylene with a wood fiber filler is used. The board core material 11 is hot press molded, cold press molded, or BMC, S
By appropriately molding and molding MC or the like, a curved surface is formed.

On the other hand, as the skin material 13, a woven cloth or a non-woven cloth can be used in addition to the PVC sheet, and in particular, a cloth is frequently used for giving an accent to the center joint portion in terms of design.

Further, below the surface of the door trim body 10, a pocket body 1 made of an injection molded body such as polypropylene or ABS is used.
4 is fixed, the size of the pocket main body 14 is set to be long in the vertical direction, and the core material 11 of the door trim main body 10 is swell-molded in the injection inner side. The inner wall surface of the main body 14 is abutted against each other via a cushioning member 16 such as urethane foam.

Furthermore, by attaching screws 17 along the lower edge of the pocket body 14 at appropriate intervals, the door trim body 10
The pocket body 14 is fixed to the.

As described above, according to the pocket structure of the present application, the upper surface 15a of the bulging portion 15 formed by drawing the core material 11 of the door trim body 10 is formed as the inner bottom surface of the pocket. It is not necessary to integrally form ribs on the inner surface, and it is possible to effectively solve the problem that a sink mark or the like occurs on the surface of the product.

Further, the core material 11 tends to be spaced apart from the pocket body 14 by the amount by which the bulging portion 15 is formed so as to increase the internal volume of the pocket, thereby increasing the storage volume of the pocket. When the core material 11 is formed by drawing, even if a variation error or an attachment error with the pocket body 14 occurs, a gap (about 2 mm between the tip portion of the bulging portion 15 and the inner wall surface of the pocket body 14) ), The cushioning member 16 such as urethane foam is interposed in a compressed state. Therefore, the elastic action of the cushioning member 16 can effectively solve the above-mentioned variation in the drawing accuracy of the core material 11, etc. Problems such as resonance can be solved, and of course, small articles stored in the pocket can be surely prevented from falling out between the pocket body 14 and the bulging portion 15.

<Effect> As described above, according to the pocket structure of the vehicle door trim according to the present invention, the buffer member can absorb the gap between the door trim body and the pocket body even if the drawing of the board core material is slightly shallow. In addition, there is no risk that small items will fall, and the precision of drawing may be rough, so that production control becomes extremely easy.

Furthermore, since the bulging part formed by drawing the board core material is used as the inner bottom surface of the pocket, ribs are not required as in the past, and it is possible to prevent defective product appearance due to sink marks as much as possible.
The aesthetics are significantly improved.

In addition, the cushioning body interposed between the board core and the pocket body causes the pocket body to vibrate during vehicle running,
It has various effects such as preventing resonance.
