Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to an improvement of a trim clip mounting structure.

《Prior art and its problems》 For example, as a means of attaching automotive interior parts such as rear side trims, roof garnishes, and various pillars to the inner panel of a car, the back side of the resin panel that is the core material of these interior parts is used. A mounting rib is formed protrudingly on the side, and after fixing a steel clip to the mounting rib, this clip is elastically fitted into a mounting hole formed on the inner panel side, allowing interior parts to be attached. is attached to the side of the inner panel.

3 and 4 show an example of a conventional trim clip mounting structure. In the drawings, a clip mounting seat 3 for mounting a clip 2 is provided on the back surface 1a of a core panel 1 of an interior component. It is installed in one piece. This clip mounting seat 3 has a pair of guide walls 4, 4 forming dovetail grooves inside, a seating plate 5 provided in the dovetail grooves so as to connect the guide walls 4, 4, and a seating plate 5. It is composed of a mounting rib 6 formed protrudingly in the center.

On the other hand, the trim clip 2 includes a clip main body 2a formed by bending a thin metal plate into a substantially U-shaped cross section;
It consists of a flange portion 2b formed by further bending both legs of the clip body 2a outward, and locking claws 2c which are cut and raised on both sides of the clip body 2a and expanded outward. There is.

To fix this trim clip 2 to the clip mounting seat 3, first place the trim clip 2 so that the lower end 2d of the clip main body 2a is on the upper surface of the seating plate 5 of the clip mounting seat 3, as shown by the arrow in FIG. After positioning, the clip body 2a of the trim clip 2 is slid in the dovetail groove so that the clip body 2a covers the mounting rib 6, and the trim clip 2 is slid until the end thereof comes into contact with the stopper rib 7.

Therefore, the trim clip 2 is
a is shaped to sandwich the mounting rib 6, and the clamping force of the clip body 2a and the downward pressing force from the guide wall 4 on the tip of the flange portion 2b act in the direction of the arrow in FIG. The clip 2 is constructed so that it does not fall off easily.

However, in the above-described mounting structure for the trim clip 2, in order to attach the trim clip 2 to the clip mounting seat 3, the trim clip 2 must first be positioned in the vertical direction.
After the positioning is completed, it is necessary to perform a sliding operation along the mounting rib 6, making the mounting work troublesome and requiring control in two directions: the vertical positioning direction and the sliding direction, which has been a major obstacle to automation.

Furthermore, since the guide wall 4 is shaped to form a dovetail groove, a slide mold must be used as the injection mold for molding the clip mounting seat 3, which increases the cost of the mold and increases the cost of the product. In addition, when a slide mold is used in this manner, it is difficult to demold the molded product, the molding cycle becomes longer, and costs inevitably increase.

<<Purpose of the invention>> This invention was made in view of the above-mentioned circumstances, and the purpose of the invention is to facilitate automation by setting the trim clip to the clip mounting seat in one direction. An object of the present invention is to provide a trim clip mounting structure which greatly reduces the number of mounting steps and allows the clip mounting seat to be manufactured easily and inexpensively.

《Structure and effects of the invention》 In order to achieve the above object, the present invention has a cross section abbreviated as U.
It consists of a letter-shaped clip body, a flange formed by bending the legs of the clip body outward, and both sides of the clip body are cut and bent so as to expand outward. In the trim clip mounting structure for attaching a trim clip equipped with a locking claw that fits into a mounting rib protrudingly formed on the back side of an interior component, the flange portion of the trim clip has a V-shaped notch. is provided, and engaging ribs are provided on both sides of the mounting rib at a position corresponding to the V-shaped notch in a direction perpendicular to the mounting rib, and the clip body is inserted into the mounting rib from above. It is characterized in that the V-shaped notch is press-fitted and fixed by engaging with the engaging rib.

That is, according to the present invention, the clip body of the trim clip is press-fitted into the mounting rib from above so as to be attached, and the V-shaped notch formed in the flange portion of the trim clip is engaged with the engagement rib. Because it is fixed, one-way control is sufficient, compared to conventional methods that require two-way control when installing trim clips, which greatly simplifies the installation process and allows for easy automation. There is an advantage that

Furthermore, the clip mounting base used in the present application is composed of a mounting rib and engaging ribs provided on both sides of the mounting rib in a direction perpendicular to the mounting rib, thereby eliminating the sliding type that was previously required. Since it is not necessary, the mold cost is reduced, the molding cycle is shortened, and the product yield is improved.

<Description of Embodiments> Hereinafter, one embodiment of the trim clip mounting structure according to the present invention will be described in detail with reference to FIGS. 1 and 2.
