Description

[Detailed Description of the Invention] <Industrial field of application> The present invention relates to an automobile interior part represented by a door trim and the like, and particularly, by simply and visually finishing the structure of a mounting portion to a vehicle body panel. The present invention relates to an interior part for an automobile, which is improved in design and is intended to reduce costs.

<Prior Art> For example, a structure for attaching the door trim 1 shown in FIG. 5 to a vehicle body panel will be described with reference to FIG.
Is substantially composed of a core material 2 formed into a required shape and a skin material 3 attached to the surface of the core material 2, and a resin molding or an iron plate is provided at a predetermined position on the back surface side of the core material 2. A bracket 4 made of, for example, is fixed by a rivet 5, and a resin clip 7 is previously attached to a clip mounting seat 6 formed in an embossed shape on the bracket 4, and the resin is provided in a mounting hole 8a of a vehicle body panel 8. The door trim 1 is attached to the vehicle body panel 8 by press-fitting and fitting the clip 7.

Further, as shown in FIG. 7, when the core material 2 is molded by injection molding, the clip mounting seat 6 can be integrally provided. In that case, the upper part of the die mounting and the upper surface of the lip mounting seat 6 are opened. Since it becomes 6a, a separate iron plate or the like is installed as the spacer 9 for closing the opening 6a so that no depression can be formed on the product surface.

Further, as shown in FIG. 8, it is possible to mold the core material 2 as shown in FIG. 8 so that the upper surface of the clip mounting seat 6 does not become the opening 6a. In this case, injection molding is performed. It requires a special mold structure that uses a slide core as the mold.

<Problems to be Solved by the Invention> As described above, when the interior parts such as the door trim 1 are generally attached to the vehicle body panel 8, the bracket 4 having the clip attachment seat 6 is usually required as shown in FIG. It has been pointed out that the number of parts is increased, the cost is increased, and the bracket 4 is fixed by the rivet 5, so that the head of the rivet 5 appears on the surface of the product, and the appearance is deteriorated. .

Similarly, as shown in FIG. 7, the clip mounting seat 6 is attached to the core member 2.
Even when these are integrally formed, the spacer 9 that closes the opening 6a appears as a convex portion on the product surface, and there are the same disadvantages as described above that the number of parts is increased by the spacer 9 and the aesthetic appearance is reduced.

Also, in the embodiment in which the clip mounting seat 6 is integrally formed by using the slide core as the resin core material, there is a drawback that the cost of the injection molding die is extremely high and the product cost is significantly increased.

This invention was made in view of such circumstances,
The object of the present invention is to improve the design of the interior parts that are attached to the vehicle body panel via clips by simplifying the structure of the clip attachment part and not affecting the product surface. Another object of the present invention is to provide interior parts for automobiles with which the cost can be significantly reduced.

<Means for Solving the Problems> In order to achieve the above object, an automobile interior part according to the present invention comprises a main body side core material and a terminal side core material, which are separated from each other. , A clip mounting seat for holding a clip for mounting on a vehicle body panel is formed to project in an embossed shape, and the terminal side core member and the main body side core member are joined so that the upper side of the clip mounting seat is covered by the main body side core member. It is characterized by being fixed.

<Function> As is apparent from the above configuration, the core material of the interior component is divided into the main body side core material and the terminal side core material, and the clip mounting seat is integrally provided on the back surface of the terminal side core material. Unlike the conventional case, it is not necessary to separately bond and fix the bracket having the clip mounting seat, and the bracket can be eliminated.

Furthermore, since the upper surface of the clip mounting seat formed on the terminal side is covered with the main body side core material, the head of the rivet or the convex portion of the spacer does not appear on the product surface.

<Example> Hereinafter, an example of an automobile interior part according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view showing the interior trim for an automobile according to the present invention applied to a door trim, and FIG. 2 is an exploded perspective view showing exploded members of the door trim. FIG. 4 is a cross-sectional view of essential parts showing a joint portion of each member.

In FIG. 1, an automobile door trim 10 is composed of four divided bodies.

That is, it is roughly composed of an upper side member 20 and a lower side member 30 which form a main body side member, and a front side member 40 and a rear side member 50 which form a terminal side member.

And the concrete composition of each member 20, 30, 40, 50 is the second
As shown in the figure, first, the upper member 20 is a core member.
A skin material 22 is attached to the surface of 21.

More specifically, the core material 21 is formed by molding a composite polypropylene resin, which is a polypropylene resin mixed with wood powder filler, into the required shape by the press molding method. Material
It is configured by attaching 22 together.

Next, the lower side member 30 is similarly formed by molding the composite polypropylene resin into a required shape by a press molding method, and as the skin material 32, the outer side member 20 has an appearance different from that of the upper side member 20, in order to give a variation, A skin material 32 based on a foamed PVC sheet is used.

Then, the upper member 20 and the lower member 30 mentioned above.
The main body member is composed of and.

Next, since the front side member 40 and the rear side member 50, which are the terminal side members, have a relatively complicated shape because they form a clip mounting seat described later, each core material 41, 51 is formed by injection molding. At the time of injection molding of the core materials 41, 51, the skin materials 42, 52 such as PVC sheets are inserted into the mold, and the front side member 40 and the rear side member 50 are molded by the insert injection method.

Next, the joint structure of these members 20, 30, 40, 50 will be described.

As shown in FIG. 3, the upper side member 20 and the lower side member 30 as the main body side member are joined to each other by forming a mounting boss 23 on the back surface of the core member 21 of the upper side member 20 in a standing manner. A mounting hole 33 is formed in the lower member 30 so as to correspond to the mounting boss 23. By matching the mounting hole 33 and the mounting boss 23 and screwing the screw 60 from the rear surface side. The upper member 20 and the lower member 30 can be easily integrated.

By the way, the feature of the present invention is that the clip mounting seat is simply and inexpensively constructed by dividing the core material of the interior part and forming the clip mounting seat on the terminal side core material. The feature is that the clip mounting seat formed on the side core material is covered to improve the appearance.

That is, the joining structure of the main body side member and the terminal side member will be described by taking the joining of the upper side member 20 and the rear side member 50 in FIG. 4 as an example. First, the rear side member 50 is as described above. It is composed of a core material 51 molded into a required shape by injection molding, and a skin material 52 such as a PVC sheet that is attached to the surface of the core material 51 during injection molding. The clip mounting seat 53 is formed on the back surface so as to have an embossed shape, and a mounting hole 54 for joining with the main body side member is formed.

On the other hand, the upper member 20 is made up of a laminated structure of a core material 21 formed into a required shape by the press molding method as described above and a skin material 22 such as a cloth, as shown in FIG. , The mounting boss 23 formed upright on the back surface of the core member 21 and the mounting hole 54 provided in the rear member 50 are aligned, and the upper member 20 and the rear member 50 are joined and integrated by the screw 60. .

Furthermore, the side edge portion of the upper side member 20 is set to a wrap structure so as to cover above the clip mounting seat 53 provided on the rear side member 50, and the flange of the upper side member 20 is formed.
The structure is such that 20a contacts the surface of the rear member 50.
The door trim 10 can be attached to the vehicle body panel 62 by press-fitting the resin clip 61 attached to the clip attachment seat 53 into the attachment hole 62a of the vehicle body panel 62.

Therefore, according to the structure of the present invention, the clip mounting seat 53 can be easily formed during the injection molding of the core member 51 of the rear member 50, and the upper member 20 is joined and fixed so as to cover the clip mounting seat 53. Since it is a conventional type, it is not necessary to attach a separate bracket as in the conventional case, the number of parts can be reduced, and the head of a rivet, which is a fixing means of the bracket, appears as a convex portion on the surface, and a clip. The spacer that covers the opening of the mounting seat does not adversely affect the surface, and the appearance and design of the product is extremely good.

In addition, joining of the lower side member 30 and the rear side member 50,
Alternatively, the joining of the upper member 20 and the lower member 30 to the front member 40 is the same as the joining structure of the upper member 20 and the rear member 50 shown in FIG. .

<Effect of the Invention> As described above, the automobile interior part according to the present invention has the following special operational effects.

(1) According to the present invention, the core material of the interior component is divided into a main body side core material and a terminal side core material, and the clip mounting seat is integrally molded when the terminal side core material is molded. As compared with the conventional structure in which the bracket having the clip mounting seat is joined and fixed to the back surface of the core member, the number of parts and the number of mounting steps can be reduced, and the cost can be significantly reduced.

(2) According to the present invention, both core materials are joined and fixed so that the upper side of the clip mounting seat provided on the back surface of the terminal side core material is covered with the main body side core material. This has the effect of effectively solving the problem that the convex portions of the head and the spacer appear on the product surface and the aesthetic appearance is significantly deteriorated.

(3) According to the present invention, since the clip mounting seat formed on the back surface of the terminal side core member is covered with the main body side core member, the upper surface of the clip mounting seat may be opened. Therefore, since it does not require a slide core, it is possible to mold the terminal-side core material in a simple injection mold, and compared with the conventional example in which the clip mounting seat is molded using the slide core, This has the effect of reducing costs.
