Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure and a mounting method of mounted parts suitable for mounting a switch unit or the like on a resin trim member as an interior material of an automobile, for example.

[0002]

2. Description of the Related Art A power window switch unit mounted on an automobile door is mounted on a resin trim member on the interior side of the door. The switch unit includes a panel portion (board) having a shape that closes an opening provided in the trim member, a switch body and an operation portion provided in the panel portion, and the panel portion is provided in the opening of the trim member. It is fixed to the peripheral edge.

To fix the above-mentioned mounted component (eg, switch unit) to the trim member, for example, as shown in FIG.
As in the mounting structure (Prior Art 1) shown in FIG. 1, the panel portion 2 attached to the trim member 1 is provided with the hook 3, and the trim member 1 is provided with the reinforcing member 4 such as trim lean force. 2 hook 3 trim member 1
By pushing the hook 3 into the opening 5 of the reinforcing member 4
I try to hook it on the edge of.

Further, as in the fixing structure for electric parts and the like described in Japanese Utility Model Publication No. 4-18917 (Prior Art 2), a bracket is held between peripheral edges of a rectangular opening formed in a base material. The electric parts such as lamps are inserted into the holes provided in this bracket, and the hook-shaped locking part provided at the back end of the electric parts is hooked on the flange end of the bracket to support the electric parts. Those adapted to do so are also known.

[0005]

In the prior art 1, when the rigidity of the trim member 1 is insufficient, it is necessary to add a reinforcing member 4 such as trim lean force to the trim member 1, and the reinforcing member 4 is mounted. It takes time and labor, and the overall structure becomes complicated, and the provision of the reinforcing member 4 causes the peripheral portion of the opening 5 to become large, and the cost is high.

On the other hand, in the case of the prior art 2, since a bracket framed in a considerably large rectangle has to be attached to the opening of the base material, the size around the opening is increased as in the case of the prior art 1, It is a cost disadvantage. Moreover, since the engaging portion at the end of the electric component is hooked on the flange end provided at the recessed position of the bracket, it is necessary to widen the opening area of the base material and the bracket.

In this case, since the opening becomes large, the rigidity of the bracket has to be made considerably high, the peripheral portion of the opening becomes larger, and the structure becomes complicated.
Moreover, when a force is applied to move the mounted electric parts such as the lamp upward, the engagement between the engaging portion and the flange end is likely to come off, which causes a problem that the holding function cannot be sufficiently enhanced. It was

Therefore, an object of the present invention is to reinforce the peripheral portion of the opening of the trim member by a simple means and to secure a mounted component securely without fixing the opening wide. An object is to provide a mounting structure and mounting method for mounting components.

[0009]

SUMMARY OF THE INVENTION A mounting structure for a component to be mounted according to the present invention, which has been developed to achieve the above object, is a base portion having a U-shaped cross section which is fitted to the peripheral portion of the opening of a resin trim member. And a clip having a holding portion that extends in a direction protruding from the opening and has a tip portion bent laterally, and a panel portion having a shape that closes the opening of the trim member, and the back surface of the panel portion. And a mounted part having a hook having a shape capable of being locked to the holding portion of the clip on its side, and the hook is hooked on the tip of the holding portion of the clip fixed to the peripheral edge of the opening of the trim member. Thus, the mounted component is fixed to the trim member.

The clip is made of, for example, a metal plate, and the metal plate may be bent to form a first holding piece along the back surface of the trim member and a second holding piece along the front surface of the trim member. Further, it is preferable that the first holding piece and the second holding piece are provided with projections having a shape that bites into the trim member, so that the clip can be more reliably fixed.

The tip portion of the holding portion of the clip is bent, for example, so as to face the outside of the opening portion, and in that case, the hook is formed so as to face the inside of the panel portion. This hook is provided so as to project at the edge of the panel or the like.

The trim member has, for example, a laminated structure having a core material and an elastic soft resin layer laminated on the outer side of the core material. In that case, the holding piece at the base of the clip is made of the soft resin. The first part of the layer is compressed.
The peripheral edge portion of the opening of the trim member is sandwiched in the thickness direction between the holding piece and the second holding piece.

[0013]

In order to fix the mounted component to the trim member using the clip, the first holding piece is bent by bending the second holding piece of the clip so that the base portion of the clip has a U-shaped cross section. After sandwiching and fixing the opening peripheral edge of the trim member between the second holding piece and the second holding piece, by pushing the hook of the panel portion toward the holding portion of the clip,
Hook the hook on the clip holder.

Thus, the panel portion of the mounted component is fixed to the trim member via the clip fixed to the peripheral edge portion of the opening of the trim member, and the peripheral portion of the opening portion of the trim member is fixed by the base portion and the panel portion of the clip. As a result, the peripheral edge of the opening can be reinforced, and the clip can hold the mounted component in a stable state.

In the mounting method of the present invention, when fixing the clip to the peripheral edge of the opening of the trim member, the second holding piece of the clip is bent (caulked) to be fixed to the peripheral edge of the opening. Compared to the case of inserting a U-shaped base into the peripheral edge of the opening, the soft resin layer of the trim member does not have problems such as curling up or wrinkling, and the clip does not open in the opening of the trim member. Since an unstable element such as returning to the edge direction can be avoided, the clip can be reliably stopped at a predetermined position.
