Description

Mounting member mounting structure

The present invention relates to a mounting structure for a mounting member for mounting the mounting member on the mounted member.

For example, when attaching a mounting member such as an interior part of an automobile to a mounting member such as a vehicle body panel, a clip is mounted on a mounting seat protruding from the mounting member, and this clip is used as a mounting hole of the mounting member. A structure is used in which the attachment member is attached to the attachment member via the clip by being engaged.

The clip used in the above structure is made of metal or resin. In Patent Document 1 below, which uses a metal clip, a clip mounting seat is provided on the back surface of the interior part, a clip made of a spring steel plate is attached to the clip, and the clip is press-fitted into the mounting hole of the vehicle body panel. Thus, a mounting structure for mounting interior parts is disclosed. The clip is formed with a flange for locking outwardly bent at both ends of a pair of leg pieces bent in an inverted U shape, and at the tip of the elastic piece formed by cutting and raising substantially the center of the leg piece. It has a shape provided with a locking portion bent outward. Further, the clip mounting seat has side wall ribs set on both sides of the support rib, and a locking groove for slidingly mounting the clip locking flange is formed on the lower inner surface of the side wall rib.

On the other hand, in Patent Document 2 below as a resin clip, a base having a U-shaped cross section having a pair of opposing side walls, a pair of elastic arms extending from the inner surfaces of the side walls, and each side wall of the base A clip with a pair of outer locking shoulders is disclosed. Then, while grasping both sides of the base of the clip, by inserting the boss part suspended from the back surface of the mounting part into the inside of the base, the pair of elastic arms engages with the engagement hole of the boss part, and the boss part A clip is installed. Thereafter, by inserting a clip into the mounting hole of the vehicle body panel, the engagement shoulder engages with the mounting hole, so that the mounting component can be mounted on the vehicle body panel.

Although the thing using the metal clip like the said patent document 1 has the advantage that attachment strength is high, it becomes difficult to isolate | separate a metal material and a resin material in the case of a scrap car etc., and manufacturing cost is also high. There were disadvantages.

On the other hand, the one using the resin clip as described in the above-mentioned Patent Document 2 has the advantage that it is not necessary to separate the material in the case of a scrap car and the manufacturing cost can be reduced. Since the pair of elastic arms are engaged with the joint hole and are prevented from coming off, there is a disadvantage that the strength against the pulling force is inferior to that of a metal clip.

Moreover, in the thing of the structure which carried out the slide of the clip sideways and was attached to a mounting seat like patent document 1, although it is also considered to make a clip into resin, in the case of such a structure, It was found that there is a problem that the resin clip slides sideways and easily comes off the mounting seat. In this case, it is conceivable that the flange portion of the clip is thickened and press-fitted into the mounting seat, but there is a problem that the insertion resistance when the clip is inserted into the mounting seat is increased and the assembling workability is deteriorated.

Therefore, the object of the present invention is to attach the mounting member so that sufficient strength can be obtained even if a resin clip is used, and the clip is not easily detached from the mounting seat and can be easily mounted on the mounting seat. To provide a structure.

In order to achieve the above object, a mounting structure for a mounting member according to the present invention includes a mounting seat protruding from the mounting member and a resin clip attached to the mounting seat, and the clip is mounted on the mounting seat. In the mounting structure of the mounting member for mounting and mounting the mounting member to the mounted member by engaging with a mounting hole formed in the mounted member, the mounting seat protrudes from the back side of the mounting member A plate-like column part, a pair of side walls erected substantially in parallel on both sides of the plate-like column part, and extending from the inner surface of each side wall toward the column part, between the column parts The clip is provided with a rib provided with a predetermined gap, and the clip includes a leg portion bent in a substantially V shape, and a pair of flange portions extending outward from both ends of the leg portion, A locking shoulder that is provided in the middle of the outer surface of the leg portion and engages with a peripheral edge of the mounting hole. The flange portion is inserted between the attachment member and the rib, respectively, and a clip is assembled to the attachment member, and the flange portion on the attachment member side and / or the rib side is configured. A protrusion is provided at an intermediate portion along the length direction of the rib, and the height from the back surface of the mounting member to the rib inner surface is H1, and the thickness of the flange portion is When H2 is set and the height of the protrusion is H3, H2 + H3> H1, and the flange portion is set to be inserted between the mounting member and the rib.

In the mounting structure of the mounting member of the present invention, it is preferable that the length L2 of the protrusion along the flange portion is 1/5 or less of the length L1 of the flange portion.

In the mounting structure of the mounting member according to the present invention, the enlarged diameter portion is formed on both side surfaces of the plate-like column portion of the mounting seat, and the clip has a bent portion from the inner surface facing the leg portion. A pair of elastic arms extending toward the mounting member, and when the clip is assembled to the mounting member, the tip ends of the pair of elastic arms are engaged with the stepped portion of the enlarged diameter portion of the column portion. It is preferable that it is comprised so that it may match.

In the mounting structure of the mounting member according to the present invention, the tip end portion of the column portion of the mounting seat is formed with tapered surfaces on both sides thereof so as to become gradually thinner toward the tip end, and the pair of flange portions Is inserted between the mounting member and the rib, and when the clip is assembled to the mounting member, the inner surface of the leg portion of the clip has a predetermined gap with respect to the tapered surface of the column portion. It is preferable that protrusions arranged to face each other are provided.

According to the present invention, when a pair of flange portions are respectively inserted between the mounting member and the rib, and the clip is assembled to the mounting member and then inserted into the mounting hole of the mounted member, it is inclined to the rear peripheral edge of the mounting hole. The shoulder is engaged, and the attachment member can be attached to the attachment member via the clip.

At this time, when the height from the back surface of the mounting member to the inner surface of the rib is H1, the thickness of the flange portion is H2, and the total height of the protrusions is H3, it is set so that H2 + H3> H1. The protrusion partially provided in the center in the length direction of the flange portion is press-fitted so as to bite into the back surface of the mounting member and / or the inner surface of the rib, and between the mounting member back surface and the flange portion on the surface provided with the protrusion. Alternatively, a gap is generated between the rib inner surface and the flange portion.

For this reason, when a pulling force acts on the clip in the direction of detaching from the mounting seat (the direction along the back surface of the mounting member), the flange portion tilts with the projection as a fulcrum, and the corner at the end in the length direction is Since it engages with the back surface of the mounting member and the inner surface of the flange portion, it is possible to make it difficult to remove the clip from the mounting seat.

In addition, since the protrusion is partially provided at the intermediate portion in the longitudinal direction of the flange portion, when the flange portion is inserted between the mounting member and the rib, an increase in insertion resistance can be suppressed. The clip can be smoothly mounted on the mounting seat.

If the length L2 of the protrusion 40 is too short, the protrusion 40 may be shaved when the clip 30 is inserted into the mounting seat 10, or the protrusion 40 may be completely buried inside the mounting member 1, and the flange portion 33 may be removed. If the length L2 of the protrusion 40 is too long, the flange portion 33 is not easily tilted effectively.

Furthermore, as shown in FIG. 3, when the height from the back surface of the mounting member 1 to the inner surface of the rib 13 is H1, the thickness of the flange portion 33 is H2, and the height of the protrusion 40 is H3 H2 + H3> H1 and the flange portion 33 is set so as to be inserted between the mounting member 1 and the rib 13. (H2 + H3) −H1 is preferably 0.1 to 0.4 mm.

Next, the usage method and the effect of the mounting structure of the mounting member according to the present invention will be described.

As shown in FIG. 1, the corresponding portions of the clip 30 are respectively aligned with the gaps of the mounting seat 10, and the

flange portions

33, 33 are gripped to slightly bend the both sides of the leg portion 31 inward. The clip 30 is pushed in from the opening side.

Then, the clip 30 is slid in the direction along the back surface of the mounting member 1 and both sides of the leg portion 31 are inserted between the column portion 11 and the

side walls

12 and 12, and the pair of

flange portions

33 and 33 are attached to the mounting member. 1 and the

ribs

13 and 13, respectively. Then, after the clip 30 is completely pushed into the mounting seat 10 and then released, both sides of the leg 31 are elastically restored, and the

flange portions

33 and 33 are engaged with the inner surface of the rib 13 so that the clip is attached to the mounting seat 10. 30 can be mounted.

At this time, when the height from the back surface of the mounting member 1 to the inner surface of the rib 13 is H1, the thickness of the flange portion 33 is H2, and the height of the protrusion 40 is H3, H2 + H3> H1. Thus, the protrusion 40 is press-fitted into the back surface of the mounting member 1 so that a gap is formed between the back surface of the mounting member 1 and the flange portion 33 (see FIG. 3).

As a result, another member collides with the side of the clip 30 and the like, as indicated by an arrow in FIG. 3, the direction in which the clip 30 is detached from the mounting seat 10, that is, the direction along the back surface of the mounting member 1. 4, the flange portion 33 tilts around the projection 40 as a fulcrum, and the corner portion C in the length direction is the back surface of the mounting member 1 or the inner surface of the flange portion 33, as shown in FIG. 4. Therefore, it is possible to make it difficult to remove the clip 30 from the mounting seat 10.

Further, since the protrusion 40 is partially provided in the intermediate portion in the longitudinal direction of the flange portion 33, the insertion resistance when the flange portion 33 is inserted between the mounting member 1 and the rib 13 is reduced. The clip 30 can be smoothly mounted on the mounting seat 10.

Further, the length L2 along the flange portion 33 of the protrusion 40 is set to be 1/5 or less of the length L1 of the flange portion 33. By forming the protrusion 40 with a small length with respect to the flange portion 33, the clip When a pulling force is applied to 30, the flange portion 33 can be easily tilted with the protrusion 40 as a fulcrum, and the clip 30 can be more reliably prevented from coming off from the mounting seat 10.

When the clip 30 is attached to the mounting seat 10, the pair of

elastic arms

36 and 36 are disposed on both sides of the column part 11, and the

engagement parts

36 a and 36 a are predetermined with respect to the step parts 16 a on both sides of the column part 11. And face each other with a gap G (see FIG. 3). Therefore, when a pulling force acts on the clip 30 and the flange portion 33 tilts with the protrusion 40 as a fulcrum, the engaging portion 36a of each elastic arm 36 is engaged with the step portion 16a of the column portion 11 as shown in FIG. Accordingly, the clip 30 can be more easily removed from the mounting seat 10 together with the flange portion 33 engaged with the back surface of the mounting member 1 and the inner surface of the rib 13.

The pair of

elastic arms

36 and 36 are disposed between the column portion 11 and the

side walls

12 and 12 in a state where the clip 30 is mounted on the mounting seat 10, and are attached to fill the gap between them (see FIG. 6). Even if an external force in a direction along the back surface of the member 1 and perpendicular to the sliding direction of the clip 30 is applied, the clip 30 can be prevented from being laterally displaced or rattling.

In a state where the clip 30 is mounted on the mounting seat 10 as described above, the clip 30 is inserted into the mounting hole 7 of the mounted member 5, and the locking shoulders 35, 35 on both sides of the leg portion 31 are inserted into the mounting hole 7. As shown in FIG. 6, it is attached to the member 5 to be attached by engaging the back side periphery and bringing the front ends of the

side walls

12, 12 of the attachment seat 10 into contact with the front side periphery of the attachment hole 7. The member 1 can be attached.

Incidentally, when the clip 30 is inserted into the mounting hole 7, both sides of the leg portion 31 are pressed against the inner periphery of the mounting hole 7, and the leg portion 31 is bent and deformed. At this time, since the

protrusions

37 and 37 are arranged to face the tapered surfaces 17 and 17 of the column part 11 with a predetermined gap (see a partially enlarged view of FIG. 5 and FIG. 6), the mounting hole 7 When both sides of the leg portion 31 are pressed to the inner circumference, the leg portion 31 is reduced in diameter and extended in the axial direction (see the dashed line and the broken line in FIG. 5), and the

protrusions

37 and 37 are strongly against the tip of the column portion. Since it moves along the tapered surfaces 17 and 17 of the column part 11 without being pressed, an increase in insertion resistance can be prevented.

In addition, since the

protrusions

37 and 37 of the clip 30 are arranged to face the tapered surfaces 17 and 17 of the column portion 11 with a predetermined gap, stress in the torsional direction or lateral direction acts on the clip 30 or the mounting member 1. However, the

protrusions

37 and 37 of the clip 30 collide with the

tapered surfaces

17 and 17 of the column part 11, and the assembly state of the clip 30 and the attachment member 1 can be maintained firmly.

Further, since the crushing restriction wall 38 is provided inside the bent portion of the leg portion 31, the rigidity of the leg portion 31 can be improved, so that the clip 30 is crushed even if a pressing force acts on the tip end portion of the clip 30. So that it can be held in a predetermined shape.

FIG. 7 shows another embodiment of a mounting structure for a mounting member according to the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the mounting structure of this embodiment, the

protrusions

40 and 40 are provided on the flange 33 of the clip 30a on the mounting member 1 side and the rib 13 side, respectively, on the intermediate portion along the length direction of the rib 13. Is provided.

At this time, when the height of the protrusion 40 on the mounting member 1 side is H3a, the height of the protrusion 40 on the rib 13 side is H3b, and the total height of both protrusions 40 is H3, It is set so that H2 (thickness of the flange portion 33) + H3> H1 (height from the back surface of the mounting member 1 to the inner surface of the rib 13).

And in the state which attached the clip 30a to the attachment seat 10, a clearance gap arises between the back surface of the attachment member 1, and the flange part 33, and between the rib 13 and the flange part 33, respectively, and drawing-out force is produced in the clip 30a. When it acts, the flange portion 33 tilts with the two upper and lower projections 40 as fulcrums, and the corner portion C in the length direction engages with the back surface of the mounting member 1 and the inner surface of the flange portion 33, and the clip 30 a is removed from the mounting seat 10. It can be made difficult to come off.

In this embodiment, since the gaps are formed on the upper and lower surfaces of the flange portion 33 by the two

protrusions

40, 40, even when the inclination of the flange portion 33 is small, the corner portion of the flange portion 33 is not attached to the back surface of the mounting member 1 or Since it engages with the inner surface of the flange portion 33, the clip 30a can be more effectively prevented from coming off from the mounting seat 10.
