Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to an improvement of a clip mounting seat provided for attaching a clip to the back side of an automobile interior part.

<Prior art and its problems> For example, in order to attach automobile interior parts such as center pillars and door trims to the car body panel, resin clips are attached to the back side of these interior parts, and this resin clip is attached to the car body side. The automobile interior parts are attached to the vehicle body panel by press-fitting them into the mounting holes.

The structure of a conventional clip mounting seat will be explained based on FIG. 3. A pedestal with an opening at one end is formed on the back surface 1a of the resin panel 1, which is the base of the interior parts, and projects parallel to the back surface 1a at a predetermined distance from the back surface 1a. A plate 2 is provided, a circular locking hole 4 for attaching a resin clip 3 is provided in the center of the pedestal plate, and the resin clip 3 is locked in the locking hole 4 through an insertion groove 5. On the other hand, the resin clip 3 includes a hollow elongated spherical fitting piece 3a that is press-fitted into a mounting hole in a vehicle body panel (not shown), and a pair of flange portions 3b that are locked in a locking hole 4 of the base plate 2. and a relatively small-diameter neck portion 3c that connects the flange portions 3b.

Recently, a robot has been used to automatically attach the resin clip 3 to the base plate 2 in order to save labor.

In this case, as shown in FIG. 4, the fitting piece 3a of the resin clip 3 is held by the chuck portion 6 fixed to the drive arm (not shown) by vacuum suction force or the like, and the height position of the pedestal plate 2 ( The drive arm is moved in the Z-axis direction in the figure so that the neck 3c of the resin clip 3 is located at this height position, which corresponds to the height relative to the back surface 1a of the resin panel 1 (indicated by the symbol l in the figure). Then, the resin clip 3 is positioned. Then, the drive arm moves in the X direction in the figure, and the resin clip 3 is inserted into the insertion groove 5.
After being engaged in the locking hole 4 through the chuck part 6
The vacuum suction force acting on the resin clip 3 is released, and the attachment of the resin clip 3 to the mounting seat is completed.

However, in such an automated clip insertion method, in order to securely install the resin clip 3 into the locking hole 4, it is necessary to first insert the resin clip 3 into the locking hole 4.
It is a prerequisite to accurately position the neck portion 3c at the height of the pedestal plate 2, but since positioning the resin clip 3 in the Z-axis direction is extremely difficult and requires highly accurate control technology, the current,
It has hardly been put to practical use, and at present the resin clip 3 is attached to the pedestal plate 2 by hand.

<Purpose of the invention> This invention was made in view of the above-mentioned circumstances, and the purpose of the invention is to provide a clip mounting seat for attaching a clip to be attached to the back side of an interior component, and to improve the positioning of the resin clip. To provide a clip mounting seat which can easily perform automatic insertion of the clip by easily and smoothly locking the clip to a pedestal plate.

<Structure and Effects of the Invention> In order to achieve the above object, the present invention is an embossed clip mounting seat provided on the back surface of an automobile interior part, which is parallel to the back surface of the interior part at a predetermined interval. A pedestal plate with an opening at one end protruding from the pedestal plate, a locking hole opened in the center of the pedestal plate for locking the flange portion of the clip, and the locking hole communicating with the opening of the pedestal plate to hold the clip. An insertion groove to be inserted into the locking hole, and an insertion groove that protrudes from the back side of the interior fixture along the locking hole and insertion groove, and extends outward from the opening of the pedestal plate by at least the diameter of the flange portion of the clip. the flange portion of the clip is brought into contact with the upper surface of the rib,
Align the height of the clip with the pedestal plate, slide the flange of the clip along the top surface of the rib, lead the clip to the opening of the pedestal plate, and insert the clip into the locking hole through the insertion groove. It is characterized by being designed to guide.

That is, according to the above configuration, when positioning the resin clip at the height of the pedestal plate on the front side of the opening of the pedestal plate, the flange portion of the resin clip is brought into contact with the upper surface of the rib protruding from the back surface of the interior component. By doing so, the resin clip can be easily positioned in the vertical direction.

Furthermore, by sliding the resin clip along the upper surface of this rib, it is possible to lead it to the opening of the pedestal plate, and also to smoothly attach the clip to the locking hole through the insertion groove.

As described above, in the present application, a rib is provided below the locking hole and the insertion groove, and the tip of the rib is set to extend outward from the opening of the base plate by at least the diameter of the flange portion of the clip. from,
This rib functions as a stopper for positioning the resin clip, as well as a guide function during insertion, and the simple addition of a protruding rib eliminates the need for precise position control technology. This has the advantage of greatly contributing to labor savings in attaching clips, such as enabling automatic insertion of clips without having to do so.

<Description of Embodiments> Hereinafter, embodiments of the clip mounting seat according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is an overall perspective view showing the clip mounting seat and resin clip formed on the back of the interior part, Figure 2
The figure is a sectional view showing a state in which a resin clip is attached to the clip attachment seat.

In FIG. 1, an embossed clip mounting seat 11 is formed on the back surface 10a of the resin panel 10 constituting the core of the interior component, and this clip mounting seat 11 protrudes from the back surface 10a of the resin panel 10. A pedestal plate 13 with an opening 12 at one end, a circular locking hole 14 formed in the center of the pedestal plate 13 into which a clip is to be attached, and a circular locking hole 14 that communicates with the locking hole 14 and the opening 12 to allow the clip to be attached. It is composed of an insertion groove 15 and a rib 16 which is protruded from the back surface 10a of the resin panel 10 in correspondence with the insertion path of the clip, and whose tip 16a extends to the outside of the opening 12.

On the other hand, the resin clip 17 includes a hollow elongated spherical elastic fitting piece 18 that is press-fitted into a mounting hole in a vehicle body panel (not shown), and a pedestal when the resin clip 17 is attached to the locking hole 14 of the clip mounting seat 11.
