JP 2004-230969 A

  In the above-described vehicle finisher mounting portion structure, when the drop-off prevention locking portion is easily inserted into the drop-off prevention hole portion, the drop-off prevention locking portion is easily removed from the drop-off prevention hole portion. Therefore, it has been studied to make it difficult for the drop-off prevention locking portion to come out of the drop-off prevention hole portion in an emergency by making it difficult to insert the drop-off prevention lock portion into the drop-off prevention hole portion.

  However, if it becomes difficult to insert the locking part for drop-off prevention into the hole part for drop-off prevention, a new problem arises that it takes time to assemble.

  Therefore, the main object of the present invention is to solve the above-described problem of the locking portion for preventing dropout.

In order to solve the above problems, the present invention provides:
For the claw holes formed in the vehicle body side panel,
By fitting the locking claw formed on the finisher member,
In the vehicle finisher mounting portion structure in which the finisher member is claw-fixed to the vehicle body side panel,
The finisher member is provided with a drop-off preventing arm portion extending longer than the locking claw in the insertion direction of the locking claw into the claw hole, and the vehicle body side panel accommodates the drop-off preventing arm portion. While providing possible dropout prevention holes,
Normally, the tip of the drop-off prevention arm is not locked to the drop-off prevention hole, and when the locking claw is released from the claw hole by an emergency input load, the drop-off prevention hole Providing a locking part for preventing falling off,
The drop-off prevention locking portion has a wide portion wider than the drop-off prevention hole portion, and
The drop-off prevention locking part or the drop-off prevention arm part twists the drop-off prevention locking part when the drop-off prevention locking part is inserted into the drop-off prevention hole part at least at the tip thereof. It has a twist-inducing guide part that is deformed and guides the wide part through the drop-off preventing hole part.

According to the present invention, the following effects can be obtained by the above-described configuration.
In other words, when the locking part for drop-off prevention is inserted into the hole part for drop-off prevention, the twist-inducing guide part forcibly deforms by guiding the locking part for drop-out prevention, thereby forcibly preventing the drop-off prevention. By changing the direction of the stop or the like, the wide portion can easily pass through the hole for preventing dropout. Accordingly, it is possible to facilitate the insertion at the time of assembling, while making the drop-off preventing locking portion difficult to be inserted into the drop-off preventing hole and difficult to come off.

<Configuration> The configuration will be described below.
As shown in FIG. 1, in a vehicle such as an automobile, a vehicle interior front panel (vehicle body side panel 1) such as an instrument panel is installed at the front of the vehicle interior. And decorative parts, such as the finisher member 2, are attached with respect to this instrument panel.

  The finisher member 2 mounting structure (vehicle finisher mounting portion structure) is, as shown in FIGS. 2 and 3, a finisher with respect to a claw hole 3 formed in the vehicle body side panel 1 such as an instrument panel. The finisher member 2 is fixed to the vehicle body side panel 1 by engaging the locking claws 4 formed on the member 2.

Here, a supplementary explanation of the above will be given. In addition, what is necessary is just to refer to supplementary explanation as needed.
The above-described “vehicle finisher mounting portion structure” is literally a structure of a mounting portion for mounting the finisher member 2 to the vehicle (vehicle body side panel 1). The vehicle finisher mounting portion structure also includes a dropout prevention structure for preventing the finisher member 2 from dropping from the vehicle body side panel 1 due to an emergency input load.

  The above-described “vehicle body side panel 1” refers to various interior panels installed in the vehicle interior. The vehicle body side panel 1 includes an instrument panel as described above, a sub-panel attached to the instrument panel, and the like. The vehicle body side panel 1 is made of resin.

  The above-mentioned “finisher member 2” is a resin decorative part attached to the vehicle body side panel 1. The finisher member 2 is made of, for example, a resin such as polycarbonate or ABS resin. The finisher member 2 is designed to have an improved design by, for example, having a metallic or wood grain surface. In this case, the finisher member 2 is an edge member that borders both side portions of the operation panel portion 5 installed at the center portion in the vehicle width direction y of the instrument panel. Therefore, the finisher member 2 has an elongated shape that extends in the vertical direction z along the side of the operation panel unit 5. In addition to the above, the finisher member 2 can be, for example, a frame-shaped member or a plate-shaped member.

  The above-described “nail hole 3” is a hole for inserting and locking the locking claw 4. The claw hole 3 is provided in a state in which the position and the size of the claw hole 3 are matched to the portion of the vehicle body side panel 1 that is covered with the finisher member 2. The claw hole 3 is, for example, a vertically long rectangular shape.

  The “locking claw 4” is a claw locking portion that is inserted into and locked in the claw hole 3. The locking claw 4 is integrally projected toward the vehicle body side panel 1 from the surface of the finisher member 2 on the vehicle body side panel 1 side or the like. There are various types of the locking claws 4, and in this example, a separate metal clip (not shown) is attached to the insertion piece 4 a extending toward the claw hole 3. Yes. In addition to the above, the locking claw 4 may be configured only by resin, for example. The above-described insertion piece 4a is, for example, an elongated strip shape (or strip shape) having a constant width in the vertical direction z. Reinforcing flanges 4c and 4d are provided on the upper and lower edges of the insertion piece 4a. The insertion piece 4 a and the upper and lower flange portions 4 c and 4 d are formed in a size matching the claw hole 3. In this case, the insertion piece 4a has a vertical surface shape and the flange portions 4c and 4d have a horizontal surface shape. However, the insertion piece 4a has a horizontal surface shape and the flange portions 4c and 4d have a vertical surface shape. It may be planar.

  In addition to the basic configuration as described above, this embodiment is provided with the following configuration (drop-off prevention structure).

(Configuration 1)
The above-described finisher member 2 is provided with a drop prevention arm portion 21 that extends longer than the locking claw 4 in the insertion direction of the locking claw 4 into the claw hole 3. Further, the above-described vehicle body side panel 1 is provided with a drop prevention hole 22 that can accommodate the above-described drop prevention arm 21.
When the locking claw 4 is released from the claw hole 3 due to an emergency input load, it is not normally locked to the drop-off preventing hole 22 at the tip of the above-described falling-off prevention arm 21. A drop prevention locking portion 23 that is locked to the drop prevention hole 22 is provided.
The dropout prevention locking portion 23 has a wide portion 24 wider than the above-described dropout prevention hole portion 22.
Further, as shown in FIGS. 4 to 7 in order, the above-described drop-off prevention locking portion 23 or drop-off prevention arm portion 21 has a drop-off prevention locking portion 23 at least at the tip thereof. When inserted into the portion 22, it has a twist-inducing guide portion 25 that twists and deforms the drop-off prevention locking portion 23 to guide the wide portion 24 through the drop-off prevention hole portion 22. .

(Supplementary explanation 1)
Here, the above-mentioned “insertion direction” is a basic attachment direction of the finisher member 2 with respect to the vehicle body side panel 1. In this case, the direction from the near side to the far side of the vehicle body side panel 1 (for example, the vehicle longitudinal direction x) is set. The locking claw 4 is extended toward this insertion direction.

  The above-mentioned “drop-off prevention arm portion 21” is, for example, an elongated belt-like one. The drop-off prevention arm portion 21 has, for example, a constant width dimension in the lateral direction (for example, the vehicle width direction y) and extends substantially in the vehicle longitudinal direction x. In this case, the drop-off prevention arm portion 21 is integrally provided so as to extend the flange portion 4c with respect to the lower flange portion 4c of the locking claw 4. The drop-off prevention arm portion 21 may be an extension of the upper flange portion 4d of the locking claw 4, or may be a dedicated one different from the locking claw 4. Further, the drop-off preventing arm portion 21 is not limited to a belt-like one, and may be, for example, a rod-like one.

  The above-mentioned “drop-off prevention hole portion 22” has a size that allows the drop-off prevention arm portion 21 to be tightly inserted. In this case, the dropout prevention hole 22 has a width dimension substantially equal to the width dimension of the dropout prevention arm section 21 and has a height dimension larger than the width dimension of the dropout prevention arm section 21. It is assumed that the rectangular shape. When the drop-off prevention arm portion 21 has a vertical surface shape, the drop-off prevention hole portion 22 has a height dimension substantially equal to the height dimension of the drop-off prevention arm portion 21, and falls off. A horizontally long rectangular shape having a width dimension larger than the height dimension of the prevention arm portion 21 is used.

  The above-described “emergency input load” is a load that acts on the finisher member 2 in an emergency. In this case, a secondary input load by an occupant or the like in an emergency is assumed.

  The above-described “drop-off prevention locking portion 23” is a claw-shaped locking portion or the like. The drop-off prevention locking portion 23 is a one-side claw portion that protrudes outward from one side portion of the drop-off prevention arm portion 21. As shown in FIG. 5 and the like, the drop-off prevention locking portion 23 is substantially parallel to the tapered insertion taper portion 23a and the surface of the vehicle body side panel 1 in order from the distal end side of the drop-off prevention arm portion 21. And a locking surface portion 23b. In this case, the drop-off prevention locking portion 23 is formed at the tip of the drop-off prevention arm portion 21 integral with the locking claw 4. And the nail | claw hole 3 in which the said latching claw 4 is inserted is used as it is as the hole part 22 for drop-off prevention. Note that the drop-off prevention locking portion 23 may be a both-side claw portion protruding outward from both sides of the drop-off prevention arm portion 21. The drop-off prevention locking portion 23 and the drop-off prevention arm portion 21 constitute a claw-like drop-off prevention portion.

  The above-mentioned “wide width portion 24” is literally a portion wider than the dropout prevention hole portion 22 in the dropout prevention locking portion 23, and the dropout prevention locking portion 23 is intentionally used to prevent the dropout. This is to make it difficult to insert into the hole 22 (and difficult to drop off). In this case, the wide width portion 24 is set to a portion from the rear portion of the insertion taper portion 23a of the drop-off prevention locking portion 23 to the locking surface portion 23b. Due to the wide portion 24, the drop-off prevention locking portion 23 has a locking amount (protrusion amount) larger than the locking amount of the locking claw 4 with respect to the claw hole 3, that is, the normal locking amount of the locking claw 4. ) And forced fitting is required. In this case, it is assumed that the protruding amount of the wide width portion 24 from the drop prevention hole 22 does not exceed the height of the drop prevention hole 22. The overhang amount is set to a minimum size that is confirmed to be within a range of, for example, about 1.5 mm to about 3 mm, and that is not deviated by simulation or the like. The In this case, for example, 1.75 mm or more.

  The “torsion-inducing guide portion 25” described above is simply configured to insert the drop-off prevention arm portion 21 into the drop-off prevention hole portion 22 in the insertion direction. Any one may be used as long as the drop-off prevention locking portion 23 is twisted and deformed so as to pass through the hole portion 22. The twist-inducing guide portion 25 can be provided on one or both of the drop-off prevention locking portion 23 and the drop-off prevention arm portion 21. The twist-inducing guide portion 25 may be provided at least partially with respect to at least the distal end portion of the drop-off prevention locking portion 23 or the drop-off prevention arm portion 21, but the range in which the insertion taper portion 23a is formed. It is preferable to provide it widely throughout.

  In this case, the twist-inducing guide portion 25 has an edge chamfered portion formed along the side edge portion with respect to the side edge portion of the dropout preventing locking portion 23 and the dropout prevention arm portion 21. The torsion direction guide portion. In this case, a pair of edge chamfered portions as the twist inducing guide portion 25 is formed with respect to the corners of the side edge portions present at the diagonal positions of the dropout preventing locking portion 23 and the dropout preventing arm portion 21. ing.

  In particular, the edge chamfered portion as the twist-inducing guide portion 25 has diagonal positions on the side where the drop-off prevention locking portion 23 faces downward (in the figure, the upper right (side edge) and the lower left (side edge). ) Etc.). The edge chamfered portion is formed at a diagonal position on the side where the drop-off prevention locking portion 23 faces upward (in the drawing, lower right (side edge) and upper left (side edge), etc.). Anyway. The twist-inducing guide portion 25 is formed, for example, at an angle substantially equal to the twist angle at which the twisted drop-off prevention locking portion 23 can pass through the drop-off prevention hole portion 22.

(Configuration 2)
As shown in FIG. 8, at the entrance edge of the above-described drop-off prevention hole portion 22, in cooperation with the above-described twist-inducing guide portion 25, the twist prevention of the drop-off prevention locking portion 23 is assisted. A deformation assisting guide portion 26 is provided.

(Supplementary explanation 2)
Here, the above-mentioned “entrance on the entry side” is an edge of the drop-preventing hole 22 on the front surface in the insertion direction of the vehicle body side panel 1. As shown in FIG. 9, a die cutting gradient of about 1% to 2% (in this case, 1.5% or the like) is usually provided at the edge on the entry side. The deformation assisting guide part 26 is provided for at least a part or all of the edge part in which the torsion inducing guide part 25 is in sliding contact.

  The “cooperation” described above is that the deformation assisting guide portion 26 does not function alone but functions in cooperation with the torsion inducing guide portion 25.

  The above-mentioned “assistant torsional deformation” means that, when the drop prevention arm portion 21 is inserted into the drop prevention hole portion 22, the drop prevention arm portion 21, the fall prevention locking portion 23, etc. It is to assist in making the torsional deformation easy to occur or reducing the force required for the torsional deformation.

  The above-mentioned “deformation assisting guide portion 26” is literally a portion that guides to assist the torsional deformation of the dropout prevention arm portion 21 and the dropout prevention locking portion 23 by the twist inducing guide portion 25. is there. The deformation assisting guide portion 26 may be of any type, but in this case, the deformation assisting guide portion 26 has a (sufficiently) large inclination angle as compared with the above-described normal mold drawing gradient. It is assumed to be an inclined surface. In addition, if it is a thing with a mere normal die-cutting gradient as shown in FIG. 9, the inclination angle is too small and it is difficult to actively use it as the deformation assisting guide portion 26.

  The above is the (first) dropout prevention structure. In addition to the dropout prevention structure described above, for example, as shown in FIG. 10 (to FIG. 12), the upper end portion of the finisher member 2, etc. Another (second) drop-off prevention structure can be provided.

  This another drop-off prevention structure includes, for example, a hook-like drop-off prevention portion 31 for preventing the finisher member 2 from dropping off due to an emergency input load. Similar to the drop-off prevention locking portion 23, the hook-like drop-off prevention portion 31 includes a drop-off prevention arm portion 31a extending longer than the locking claw 4 in the insertion direction and the drop-off prevention arm portion. And a hook portion 31b provided so as to be bent upward with respect to the tip end portion of 31a.

  The hook portion 31b has a substantially constant thickness larger than the drop-off preventing arm portion 31a, and the tip portion bent upward is attached to the vehicle body side panel 1 with the finisher member 2 attached to the vehicle body side panel 1. It is assumed that the curvature is relatively large so as to be located above the upper edge of the drop-off preventing hole 32 formed in the panel 1. The drop-off preventing hole 32 has a height dimension substantially equal to the thickness of the hook portion 31b. Thereby, the hook part 31b cannot be inserted linearly with respect to the insertion direction of the locking claw 4 (that is, cannot be removed by linear movement). Therefore, in order to pass the hook part 31b of the drop-off prevention part 31 through the drop-off prevention hole part 32, a non-linear attachment method in which the finisher member 2 is rotated downward with respect to the vehicle body side panel 1. Need to do. As a result, it is not possible to mount the finisher member 2 sideways so that the drop prevention latch 23 is inserted into the drop prevention hole 22 described above. That is, the above-described another drop-off prevention structure restricts the way in which the drop-off prevention locking portion 23 is attached. As long as the hook portion 31 b of the drop-off prevention portion 31 enters the drop-off prevention hole portion 32, thereafter, the finisher member 2 is linearly moved in the insertion direction of the locking claw 4 with respect to the vehicle body side panel 1. It can be moved and installed.

  Furthermore, one or more locking surface portions 31c that can be locked to the upper edge portion of the drop-off prevention hole 32 in an emergency with respect to the tip portion of the drop-off prevention arm portion 31a or the upper side portion of the tip side (for example, two steps). (Or multiple stages).

  In addition, the above-mentioned drop-off prevention part 31 is detached so that the lower end part of the finisher member 2 rotates upwardly about the upper end part (the hook part 31b) (disengagement by movement in the direction opposite to the attachment direction). On the other hand, it is difficult to stop.

  Therefore, for example, by forming the rotation preventing claw portion 33 that can be locked to the lower edge portion of the claw hole 3 with respect to the lower side portion of the front end side of the locking claw 4 described above, the finisher member 2 You may make it difficult to produce the upward rotation.

  Furthermore, in the event that the above-described rotation preventing claw portion 33 is detached and the finisher member 2 is turned upward, the above-described falling-off preventing structure and the falling-off preventing portion 23 are prevented. The hole 22 may be installed at a position that is advantageous for preventing the finisher member 2 from dropping off with rotation. That is, a drop-off prevention structure and another drop-off prevention structure may be provided in a functionally related manner.

  The position that is advantageous for preventing the finisher member 2 from falling off due to the rotation is, for example, the center portion in the up-down direction z or a position below the center portion in the finisher member 2 that is elongated in the up-down direction z. . In this way, by installing the drop-off prevention locking portion 23 and the drop-off prevention hole 22 at the center of the finisher member 2 or a position below the center, the drop-off due to the rotation of the finisher member 2 is prevented. In addition to this, the finisher member 2 can be made more difficult to fall off against an emergency input load from various directions.

<Operation> The operation of this embodiment will be described below.
By bringing the finisher member 2 close to the vehicle body side panel 1 such as an instrument panel and fitting the locking claw 4 formed on the finisher member 2 into the claw hole 3 formed on the vehicle body side panel 1, The finisher member 2 is claw-fixed to the vehicle body side panel 1.

  At this time, the drop prevention arm portion 21 and the drop prevention locking portion 23 extending longer than the locking claw 4 are accommodated in the drop prevention hole portion 22 provided in the vehicle body side panel 1. When the locking claw 4 is detached from the claw hole 3 due to an emergency input load, the falling prevention locking portion 23 provided at the tip of the falling prevention arm portion 21 is locked to the falling prevention hole portion 22. It will be.

  Due to the locking of the drop-off prevention locking portion 23 with respect to the drop-off prevention hole portion 22, the finisher member 2 is prevented from falling off in an emergency.

  Further, since the drop-off prevention locking portion 23 has the wide width portion 24 wider than the drop-off prevention hole portion 22, the drop-off prevention locking portion 23 is difficult to come off from the drop-off prevention hole portion 22. It is comprised so that it may become.

<Effect> According to this embodiment, the following effects can be obtained.
(Effect 1)
When inserting the drop prevention latch 23 into the drop prevention hole 22, the torsion inducing guide 25 guides the drop prevention latch 23 and twists and deforms, so that FIGS. As shown in order, the wide portion 24 can be easily passed through the drop-off prevention hole 22 by forcibly changing the direction of the drop-off prevention locking portion 23 and the like. Accordingly, it is possible to facilitate the insertion at the time of assembling while making the shape of the locking portion 23 for preventing the drop-out to be difficult to insert into the hole 22 for preventing the drop-out and to prevent the drop-off preventing portion 23 from being pulled out.

(Effect 2)
The deformation assisting guide portion 26 provided at the entrance edge of the dropout prevention hole portion 22 cooperates with the torsion induction guide portion 25 to assist the twisting deformation of the dropout prevention locking portion 23. Further, it is possible to easily cause the torsional deformation of the drop-off prevention arm portion 21 and the drop-off prevention locking portion 23, and to reduce the force required for the torsional deformation, thereby further simplifying the assembly. Can do.
