Description

  The present invention relates to a clip mounting structure for mounting a clip to an assembly component when the assembly component is assembled to a main body component using a clip.

Conventionally, when assembling parts such as a center panel to a body part such as an instrument panel of an automobile, a resin clip is previously attached to the assembly part, and the clip of this assembly part is formed on the body part. The assembly parts are assembled to the main body parts by being fitted into the formed holes (see, for example, Patent Document 1). Patent Document 1 discloses a structure in which a clip mounting seat is provided on an assembly component as a clip mounting structure in which the clip is mounted on the assembly component in advance. The mounting seat has a rib protruding from the assembly component. On the other hand, the clip has a head and a pair of sandwiching pieces that extend away from the head. A through hole is formed in the head of the clip, through which the leading end of the mounting seat rib protrudes. And when attaching the clip to the assembly part, the tip of the rib of the mounting seat is inserted into the through hole in the head of the clip, and after temporarily assembling the rib with a pair of holding pieces, the tip of the rib The portion is melted and deformed into a shape that does not come out of the through hole of the clip and solidified. This prevents the clip from falling off the assembly part.

On the upper surface of the locking piece 24, a protrusion 24a is formed in the middle in the longitudinal direction, and a protrusion 24b that protrudes upward and extends in the width direction is formed at the tip.

  Next, the case where the clip 20 configured as described above is attached to the center panel 1 will be described. First, after the clip 20 is positioned as indicated by a virtual line in FIG. 4, the left stopper portion 17 and the right stopper portion are arranged. Insert between 19 At this time, since the front end surfaces 17b and 19b of the left stopper portion 17 and the right stopper portion 19 are inclined as described above, the clip 20 is in sliding contact with the front end surfaces 17b and 19b in the horizontal direction of the mounting seat 10. Guided to the center. When the clip 20 is inserted further deeply, the left extension 16 is bent to the left and the left stopper 17 is displaced to the left by the insertion force of the clip 20, the right extension 18 is bent to the right and the right stopper 19 is moved to the right. Displace. Thereby, as shown by a solid line in FIG. 4, the head 21 of the clip 20 gets over the left stopper portion 17 and the right stopper portion 19 to cover the front portion of the central plate portion 12, and the first clamping The piece portion 22 and the second holding piece portion 23 come along the lower surface and the upper surface of the central plate portion 12, and the claw portions 22 b and 23 b enter the through holes 12 a of the central plate portion 12. This completes the mounting of the clip 20.

  In this state, as shown in FIG. 5, the left stopper portion 17 and the right stopper portion 19 are positioned so as to face the head portion 21 of the clip 20. Accordingly, when the claws 22b and 23b of the clip 20 are likely to be detached from the peripheral edge portion of the through hole 12a, the clip 20 is prevented from moving to the front side, which is the protruding direction of the mounting seat 10. Further, the clip 20 is also prevented from moving in the width direction by the left side plate portion 13 and the right side plate portion 14.

  As described above, according to the clip mounting structure according to this embodiment, the left stopper portion 17 and the right stopper portion 19 of the mounting seat 10 are connected to the clip 20 with the clip 20 attached to the mounting seat 10 of the center panel 1. The clip 20 can be prevented from moving in the protruding direction of the mounting seat 10 by these stopper portions 17 and 19. As a result, the clip 20 can be prevented from detaching from the center panel 1 without melting the mounting seat 10 as in the conventional example, so that the equipment for melting the mounting seat 10 is not necessary and the number of man-hours is reduced. And cost reduction can be achieved.

  In the above-described embodiment, the two stopper portions 17 and 19 are provided on the mounting seat 10. However, the present invention is not limited to this, and one stopper portion may be provided.

  As shown in FIG. 7, when the clip 20 is mounted on the mounting seat 10, the first clamping piece 22 of the clip 20 is connected to the front end portion of the central plate portion 12, the left stopper portion 17, and the right stopper portion. You may make it insert from 19 toward the back side. At this time, since the opposing surfaces 17a and 19a of the left stopper portion 17 and the right stopper portion 19 are inclined as described above, the first sandwiching piece portion 22 can be guided to the rear side and inserted smoothly. Can do. That is, the facing surfaces 17a and 19a serve as guide surfaces that guide the clip 20 to the mounting seat 10 in the mounting direction.

  Then, while the clip 20 is elastically deformed, the second holding piece portion 23 is further moved in the same direction along the upper surface of the central plate portion 12. Then, the head 21 becomes a position covering the front part of the central plate part 12, and the shapes of the first sandwiching piece part 22 and the second sandwiching piece part 23 are restored to the lower surface and the upper surface of the central plate part 12, respectively. The claw portions 22 b and 23 b enter the through hole 12 a of the central plate portion 12. This completes the mounting of the clip 20.

  Further, as in Modification 1 shown in FIGS. 8 and 9, the left side plate portion 13 is provided between the left side extension portion 16 side and the central plate portion 12, and the right side plate portion 14 is provided with the right side extension portion 18 side and the central plate portion. The slit-shaped cutout portions 30 and 31 extending in the protruding direction of the central plate portion 12 may be formed between them. Thereby, since the base end side of the left side extension part 16 and the right side extension part 18 leaves | separates from the center board part 12, these extension parts 16 and 18 become easy to bend and deform. Therefore, when the clip 20 is attached to the mounting seat 10 as shown in FIG. 4, the left extension 16 and the right extension 18 are easily deformed, and the left stopper 17 and the right stopper 19 are attached to the clip 20. It can be displaced so as not to interfere with the installation. Thereby, even if the protrusion amount of the left stopper part 17 and the right stopper part 19 is increased, the mounting workability of the clip 20 is not deteriorated. Further, by forming the notches 30 and 31 in this way, the stoppers 17 and 19 can be easily displaced even when the protruding lengths of the left extension 16 and the right extension 18 are shortened. The mounting seat 10 can be reduced in size. Further, in the first modification, the cutout portion may be formed only on one of the left and right sides.

  Further, as in Modification 2 shown in FIG. 10, the stopper portion 32 may have a bridge shape that connects the left extension 16 and the right extension 18. Thereby, it is possible to reliably prevent the clip 20 from moving in the protruding direction of the mounting seat 10. Reference numeral 32 a is a facing surface that faces the head portion 21 of the clip 20. The facing surface 32a is inclined similarly to the facing surfaces 17a and 19a. In the second modification, when the clip 20 is attached to the mounting seat 10, the first clamping piece 22 of the clip 20 is connected to the front end portion of the central plate portion 12 of the mounting seat 10 as shown by a virtual line in FIG. 11. Then, it is inserted from the left stopper portion 17 and the right stopper portion 19 toward the rear side. At this time, the facing surface 32a serves as a guide surface for guiding the clip 20 in the mounting direction of the mounting seat 10.

  In addition, as in Modification 3 shown in FIG. 11, an inclined surface 12 d may be formed on the lower surface of the front portion of the central plate portion 12 so as to be inclined upward toward the front. In the third modification, when the first clamping piece portion 22 of the clip 2 is inserted from the front end portion of the central plate portion 12 and the stopper portion 32 toward the rear side, the inclined surface 12d causes the rear portion to move rearward. I can guide you. That is, the inclined surface 12d constitutes the guide surface of the present invention.

  Further, as in Modification 4 shown in FIG. 12, a stepped portion 12 c may be formed on the lower surface of the front portion of the central plate portion 12 to make the front portion thin. By thinning the front portion of the central plate portion 12 in this way, the first clamping piece portion 22 of the clip 20 is inserted more smoothly when inserted between the stopper portion 32 and the central plate portion 12. be able to. In the fourth modification, the vertical dimension of the stopper portion 32 is also shortened.

  When the stopper portion 32 is formed so as to connect the left extension portion 16 and the right extension portion 18 as in Modification 5 shown in FIG. 13, the opposing surface 32 a of the stopper portion 32 extends in the front-rear direction. You may form in. Thereby, when inserting the 1st clamping piece part 22 of the clip 20 between the stopper part 32 and the center board part 12, it can insert more smoothly.

  Further, the orientation and number of the mounting seats 10, the arrangement position, and the like can be arbitrarily set.

  In addition to the assembly of the center panel 1, the present invention can be applied to the case where interior materials such as a vehicle door trim, a switch panel, and a console box lid are assembled to a main body part.
