An embodiment of a hook mounting structure, which is an example of a vehicle interior component, will be described below with reference to the drawings.

In the drawings for explaining this embodiment, unless otherwise specified, the first direction, which is the axial direction of the insertion shaft portion of the hook, is indicated by an arrow X, and the second directions perpendicular to the first direction X and perpendicular to each other are indicated by an arrow X. A direction and a third direction are indicated by arrow Y and arrow Z. FIG.

As shown in FIGS. 1 and 2, the mounting structure 1 of the present embodiment is a structure related to mounting (or also referred to as "mounting") of the hook 10, and generally includes the hook 10 as an interior component and the vehicle. A deck trim 20 as an interior material constituting a luggage compartment and a vehicle body panel 30 are provided.

The hook 10 has an insertion shaft portion 11 extending in the first direction X, a circular head portion 13 joined to the insertion shaft portion 11 , and a disk-shaped pedestal portion 14 . A space between the head portion 13 and the pedestal portion 14 is typically used as a hooking area on which baggage, articles, and the like can be hooked. Additional hooking areas may be added to this hooking area on the hook 10 if desired.

The pedestal portion 14 is configured as a flange portion facing the deck trim 20 . The pedestal portion 14 is provided with a marking 16 protruding radially outward from a part of its peripheral surface. The marking 16 is configured as a mark by which the rotation position of the boss 15 (to be described later) can be indirectly confirmed when the hook 10 is attached. Although the material of the hook 10 is not particularly limited, it is preferable to use a resin material as the material of the hook 10 in consideration of moldability, weight reduction, and the like.

The deck trim 20 is provided with a base portion 21 having a mounting seat surface 21 a for the base portion 14 of the hook 10 . In the following description, of the two surfaces in the first direction X of the base portion 21 of the deck trim 20, the surface facing the passenger compartment (mounting seat surface 21a) is the front surface, and the surface facing the vehicle body panel 30 is the back surface.

When the hook 10 is attached, the pedestal portion 14 is pressed against the attachment seat surface 21 a that is the surface of the base portion 21 . The base portion 21 is provided with one through-hole 22 whose through-hole direction is the first direction X. As shown in FIG. This through hole 22 serves as a target hole when the hook 10 is assembled.

The vehicle body panel 30 is provided with one mounting hole 31 extending through the first direction X. As shown in FIG. The vehicle body panel 30 is arranged on the deck trim 20 in the first direction X with a facing space S (see FIG. 3) therebetween. At this time, the deck trim 20 and the vehicle body panel 30 are preferably arranged so that the positions of the through holes 22 and the mounting holes 31 in the first direction X are generally aligned.

As shown in FIG. 3, a clip 12 as a fitting portion is provided at the tip of the insertion shaft portion 11 of the hook 10 on the axis L. As shown in FIG. The clip 12 is configured to fit into the mounting hole 31 of the vehicle body panel 30 when the insertion shaft portion 11 is inserted into the through hole 22 of the deck trim 20 . The clip 12 is made of an elastically deformable material (typically a resin material) and is configured to extend radially outward from the edge of the mounting hole 31 . The clip 12 fits into the mounting hole 31 in a state of being elastically deformed so as to be crushed radially inward by press fitting. As a result, the insertion shaft portion 11 inserted through the through hole 22 generates a locking force to lock the vehicle body panel 30 . On the other hand, when the hook 10 is pulled by a load exceeding this locking force, the fitting between the clip 12 and the mounting hole 31 is released, and the insertion shaft portion 11 can be extracted from the through hole 22 .

A base portion 14 of the hook 10 is provided with a boss 15 as a rotation restricting portion. The boss 15 engages with the through-hole 22 of the deck trim 20 when the insertion shaft portion 11 is inserted into the through-hole 22 of the deck trim 20 and functions to restrict the rotation of the insertion shaft portion 11 about the axis.

The operator cannot directly see the boss 15 because the boss 15 is shielded by the pedestal 14 when viewed from the head 13 side. Therefore, in the present embodiment, the bosses 15 and the markings 16 (see FIGS. 1 to 3) are aligned in the circumferential direction on the base portion 14. As shown in FIG. As a result, the operator can indirectly visually recognize the position of the boss 15 through the marking 16 .

In the mounting structure of this embodiment, when the mounting of the hook 10 is completed, the hook 10 is pressed against the portion of the clip 12 fitted in the mounting hole 31 of the vehicle body panel 30 and the pedestal portion 14 of the deck trim 20 . The base portion 21 and the support portion 24 of the deck trim 20 on which the boss 15 is supported support at least three points.

The deck trim 20 includes a space filling portion 23 that fills the facing space S between the vehicle body panel 30 and a support portion 24 that supports the boss 15 of the hook 10 in the load acting direction Y1 in which the hook 10 receives the external load F. have.

As shown in FIGS. 3 to 5, the space filling portion 23 extends from the rear surface of the base portion 21 toward the vehicle body panel 30. As shown in FIGS. The space-filling portion 23 is a cylindrical enclosing rib provided on the rear surface of the base portion 21 so as to surround the through hole 22 , and the extending end surface thereof is configured to abut on the vehicle body panel 30 .

By providing the space-filling portion 23 in the deck trim 20, it is possible to prevent the mounting seat surface 21a of the base portion 21 from being deeply recessed toward the vehicle body panel 30 and to make the mounting seat surface 21a shallow. Therefore, the appearance of the design surface of the deck trim 20 can be improved, and usability can be improved so that the hook 10 can be easily used by the user. On the other hand, by abutting the extending end surface of the space filling portion 23 against the vehicle body panel 30, the rigidity of the deck trim 20 against the load received from the hook 10 can be increased.

Regarding the position of the space filling portion 23 when providing the space filling portion 23 on the back surface of the base portion 21 of the deck trim 20, the space filling portion 23 is positioned inside the outer shape of the pedestal portion 14 when the hook 10 is assembled. preferably set. As a result, even if a sink occurs on the surface of the base portion 21 due to shrinkage during molding of the deck trim 20 , the sink can be covered with the pedestal portion 14 of the hook 10 . Therefore, it is possible to prevent the appearance of the design surface of the deck trim 20 from being deteriorated due to the influence of sink marks.

As shown in FIG. 3, the head 13 of the hook 10 is subjected to an external load F in the direction of load action Y1 as a load when a load, article, or the like is hooked. At this time, the downward load acting on the boss 15 of the hook 10 can be received by the support portion 24 from below. This support portion 24 is preferably configured by a part of the space filling portion 23 . Thereby, the structure for supporting the boss 15 can be simplified.

As shown in FIG. 4, the through-hole 22 of the deck trim 20 has a shape, when viewed in the first direction X, in which a circular first hole portion 22a and a rectangular second hole portion 22b are coupled to each other. It has a keyhole shape. This keyhole shape is determined based on the respective cross-sectional shapes of the insertion shaft portion 11 of the hook 10 and the boss 15 . The first hole portion 22a is sized so that its inner diameter is larger than the outer diameter of the insertion shaft portion 11 and the insertion/removal operation of the insertion shaft portion 11 is not hindered. The second hole portion 22b is dimensioned so that its width dimension in the third direction Z is slightly larger than the dimension of the boss 15 in the same direction. In this embodiment, the width dimension in the third direction Z of the second hole portion 22b is smaller than the inner diameter of the first hole portion 22a.

Regarding the shape of the keyhole of the through hole 22, the shape of the first hole portion 22a does not have to be strictly circular. . Similarly, the shape of the second hole portion 22b does not have to be a strict rectangle, and it is sufficient if it is substantially rectangular, such as a rectangle or a rectangle with its corners chamfered or rounded.

The boss 15 of the hook 10 is engaged with the deck trim 20 by being inserted into the second hole portion 22b of the through hole 22 while the insertion shaft portion 11 is inserted into the first hole portion 22a of the through hole 22. It is configured to restrict the rotation of the insertion shaft portion 11 in the direction around the axis. As a result, the hook 10 can be prevented from rotating using the keyhole-shaped through hole 22 provided in the deck trim 20 .

As shown in FIGS. 3 to 5, the deck trim 20 is provided with a recessed wall portion 25 formed by recessing the base portion 21 toward the back side. The recessed wall portion 25 is configured to have a substantially U shape when viewed in the second direction Y. As shown in FIG. A housing space 25 a defined by the recessed wall portion 25 is a space for housing the boss 15 inserted into the second hole portion 22 b of the through hole 22 . When the boss 15 is housed in the housing space 25 a , the movement of the insertion shaft 11 in the direction around the axis is restricted by the recessed wall 25 .

Next, a procedure for assembling the hook 10 will be described with reference to FIGS. 6 to 8. FIG. 6, the deck trim 20 and the vehicle body panel 30 are shown separated in the first direction X for convenience of explanation.

Then, aiming at the through hole 22 of the deck trim 20 , the insertion shaft portion 11 of the hook 10 is inserted into this through hole 22 .

As shown in FIG. 7, when the position of the boss 15 of the hook 10 matches the position of the second hole portion 22b of the through hole 22, the clip 12 is engaged with the mounting hole 31 of the vehicle body panel 30 until the hook is engaged. It becomes possible to continue the insertion of the insertion shaft portion 11 of 10 . At the normal position P<b>1 of the hook 10 , the insertion shaft portion 11 is locked to the vehicle body panel 30 by fitting the clip 12 into the mounting hole 31 . At this normal position P1, the boss 15 of the hook 10 is inserted into the second hole portion 22b of the through hole 22, and its rotation in the direction D around the axis is restricted by the recessed wall portion 25. As shown in FIG. At this time, the operator can easily determine whether or not the hook 10 is assembled incorrectly by indirectly visually recognizing the position of the boss 15 through the marking 16 .

On the other hand, when the insertion shaft portion 11 of the hook 10 is inserted into the through hole 22, the position of the boss 15 deviates from the position of the second hole portion 22b of the through hole 22 and interferes with the surface of the base portion 21. is assumed. At this time, the hook 10 is at the incomplete position P2 as shown in FIG. cannot be mated to Therefore, when the hook 10 is at the incomplete position P2, the hook 10 is moved in the assembly adjustment direction (in FIG. Rotate in some clockwise direction D1). Thereby, the hook 10 can be set at the normal position P1 (see FIG. 7).
