[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automobile interior part mounting structure that is attached to a vehicle body panel via an iron clip, and in particular, even when the thickness of the panel flange to which the iron clip is inserted and fixed occurs, a constant desorption strength is always obtained. Moreover, the present invention relates to a mounting structure for interior parts for automobiles that can share an iron clip.
[0002]
[Prior art]
For example, a kicking plate is attached to a step portion of the vehicle so as to cover a side sill panel on the vehicle body side. FIG. 9 shows a structure for attaching the kicking plate 1 to the side sill panel 2. Normally, the kicking plate 1 is attached to the side sill panel 2 via an iron clip 3.
[0003]
More specifically, the iron clip 3 is mounted on a plate-like mounting seat 1a projecting vertically downward from the back surface of the kicking plate 1, and an iron flange 3c between the side sill inner 2a and the side sill outer 2b of the side sill panel 2 is attached to the iron clip 3. The kicking plate 1 is attached to the side sill panel 2 by the clip 3 being inserted and fixed.
[0004]
As shown in FIG. 10, the iron clip 3 has a substantially S-shaped cross section so that the mounting seat 1a of the kicking plate 1 and the joining flange 2c of the side sill panel 2 can be inserted from opposite directions. . Specifically, a first groove 3a for inserting the mounting seat 1a is set, and a locking claw 3b for engaging with the mounting seat 1a is formed at the end of the first groove 3a. In addition, a second groove 3c for inserting the joining flange 2c is set, and similarly, a locking claw 3d for engaging with the joining flange 2c is formed at the end of the second groove 3c.
[0005]
[Problems to be solved by the invention]
Thus, conventionally, in order to attach the kicking plate 1 to the side sill panel 2 via the iron clip 3, the mounting seat 1a is inserted into the first groove 3a of the iron clip 3 having a substantially S-shaped cross section. With the iron clip 3 held on the back side of the kicking plate 1 in an appropriate mounting posture, the second groove 3c of the iron clip 3 is inserted into the joining flange 2c of the side sill panel 2 so that the kicking plate 1 is attached to the side sill panel. It is attached so as to cover the indoor surface of 2.
[0006]
However, due to the difference in specifications, the thickness of the joining flange 2c of the side sill panel 2 is often changed within the range of 2.9 to 4.8 mm, and when the thickness difference occurs in the joining flange 2c, There is a difference in engagement force when the joining flange 2c is inserted into the second groove 3c of the iron clip 3 and engaged by the engagement claw 3d. For example, when the plate thickness of the joining flange 2c is as thick as 4.8 mm, an excessive insertion force is required at the time of mounting. Conversely, when the plate thickness is as thin as 2.9 mm, the mounting force is Although a large amount is not required, there is a problem that it is difficult to ensure a smooth mounting operation or a reliable mounting strength because it affects the engagement / disengagement force, such as coming off with a little force.
[0007]
In addition, in order to cope with a change in the thickness of the joining flange 2c of the side sill panel 2, when using the iron clip 3 having different specifications, it is necessary to prepare various iron clips 3 having different specifications, which may result in high costs and errors. Invited to wear, could not be a useful measure.
[0008]
SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and in a mounting structure for an automotive interior part in which an automotive interior part made of a synthetic resin molded body is attached to a body panel via an iron clip, the joint flange of the body panel Even if there is a change in the plate thickness due to differences in specifications, a mounting structure for automotive interior parts that can ensure a certain level of attachment / detachment strength, such as the mounting force and pulling force of an iron clip, and enables the sharing of an iron clip is provided. For the purpose.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is configured to insert and mount the first groove portion of the iron clip having a substantially S-shaped cross section to the mounting seat on the back surface of the interior part of the automobile to hold the iron clip. In the mounting structure for interior parts for automobiles, in which the second groove is inserted and fixed to the joint flange of the vehicle body panel, the separation dimension between the mounting seat and the joint flange is adjusted in accordance with the plate thickness change of the joint flange. And the attachment / detachment strength of the iron clip is controlled to be constant by maintaining the total thickness of the iron clip mounting portion constant.
[0010]
Here, the interior parts for automobiles attached to the vehicle body panel are composed of synthetic resin injection-molded bodies and mold press-molded bodies, and are provided with mounting seats for holding iron clips at predetermined positions on the back surface.
[0011]
For example, the present invention is applied to a kicking plate attached to a side sill panel, a dash side attached to a dash side panel, and the like. Further, as a separation dimension adjusting means between the mounting seat and the joint flange of the panel, a contact rib is projected on the panel-facing surface of the mounting seat, or flanges that contact the panel are integrally formed on both sides of the mounting seat. It is possible.
[0012]
As is apparent from the above configuration, according to the present invention, when the thickness of the joining flange of the panel is large, the panel abutment rib formed on the mounting seat provided on the back surface of the interior part or the panel contact The contact flange is adjusted to a relatively small height, and conversely, if the thickness of the panel joint flange is small, the height of the panel abutment rib provided on the mounting seat or the panel contact flange If the size is adjusted to a large size, the total thickness of the mounting portion, which is the total of the thickness of the mounting seat and the clearance between the mounting seat, the joint flange, and the plate thickness of the joint flange, can be controlled to a constant value. Therefore, even when there is a change in the thickness of the joining flange, the insertion force when inserting the iron clip into the joining flange and the pulling force when pulling the iron clip out of the joining flange can always be controlled to be constant. Can be carried out smoothly, and it can be prevented from falling off inadvertently, and a reliable mounting strength for interior parts can be ensured.
[0013]
Furthermore, it is not necessary to prepare an iron clip with different specifications according to changes in the thickness of the panel joining flange, and the iron clip can be shared even if there is a difference in the specifications of the panel joining flange.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a preferred embodiment of an automobile interior part mounting structure according to the invention will be described in detail with reference to the accompanying drawings.
[0015]
FIG. 1 is a perspective view showing a kicking plate to which the mounting structure according to the present invention is applied, FIG. 2 is a sectional view showing a state in which the kicking plate is attached to a side sill panel, and FIG. 4 and FIG. 4 are perspective views showing the mounting seat of the kicking plate, FIGS. 5 and 6 are explanatory views showing the form of the mounting structure according to the present invention, and FIGS. 7 and 8 are modified examples of the mounting structure of the kicking plate. It is each perspective view of the attachment seat which shows.
[0016]
First, based on FIG. 1 thru | or FIG. 6, embodiment which applied the attachment structure to the side sill panel of a kicking plate about one Embodiment of this invention is described.
[0017]
The kicking plate 10 shown in FIG. 1 is made of an injection molded product of PP (polypropylene) resin, and is mounted in the longitudinal direction of the vehicle so as to be attached along the side sill panel located at the lower edge of the door opening of the vehicle. It is set in the shape which has the elongate shape which follows and has a curved surface on the indoor side.
[0018]
To attach the kicking plate 10 shown in FIG. 1 to the vehicle body panel, as shown in FIGS. 2 and 3, the iron clip 20 is attached to the plate-like mounting seat 11 formed to project from the back surface of the kicking plate 10. In this state, it is attached to the side sill panel 30 via the iron clip 20. The side sill panel 30 includes a side sill inner panel 31 and a side sill outer panel 32, and the iron clip 20 is attached to a joint flange 33 that joins both the panels 31 and 32.
[0019]
The iron clip 20 has a substantially S-shaped cross section. That is, in order to insert the mounting seat 11 of the kicking plate 10, the first groove portion 21 with the opening facing upward is formed, and the locking claw 22 for engaging with the mounting seat 11 of the kicking plate 10 includes Cut and raised near the opening of the first groove. On the other hand, in order to engage with the joining flange 33 of the side sill panel 30, the second groove portion 23 whose opening faces downward is formed, and the locking claw 24 for engaging with the joining flange 33 has the second groove portion 23. It is cut and raised near the opening.
[0020]
By the way, in the present invention, the iron clip 20 can be used in common even if the thickness of the joining flange 33 in the side sill panel 30 varies depending on the specification, and the mounting force and the pulling force of the kicking plate 10 can be shared. Can be kept constant. For this purpose, as shown in FIG. 4, a panel abutment rib 12 is provided on the surface 11 a facing the joint flange 33 in the mounting seat 11 integrally formed on the back surface of the kicking plate 10, and the height dimension of the panel abutment rib 12 is provided. By adjusting (indicated by d1 in FIG. 4), the engagement / disengagement force of the iron clip 20 can be kept constant even when the thickness of the joining flange 33 having different specifications is changed, and the common iron clip 20 is used. The feature is that it was possible.
[0021]
5 shows the mounting structure of the present invention when the plate thickness of the joining flange 33 is set to the maximum dimension of 4.8 mm. FIG. 6 shows the plate thickness of the joining flange 33 set to the minimum dimension of 2.9 mm. The attachment structure in the case of doing is shown, respectively.
[0022]
For example, as shown in FIG. 5, when the joining flange 33 in the side sill panel 30 is set to a large size such as 4.8 mm, it protrudes from the panel facing surface 11 a of the mounting seat 11 of the kicking plate 10. The panel abutment rib 12 is set to have a small height dimension d1.
[0023]
And in order to attach the kicking plate 10 to the side sill panel 30, in the state which inserted and attached the mounting seat 11 of the kicking plate 10 in the 1st groove part 21 in the iron clip 20 with a substantially S-shaped cross section, the 1st of the iron clip 20 is attached. If the joining flange 33 of the side sill panel 30 is inserted into and fixed to the groove portion 23, the total thickness (indicated by A in FIG. 5) of the attachment portion in this case is the plate thickness (4.8 mm) of the joining flange 33 + attachment It is the plate thickness (1.3 mm) of the seat 11 + the height dimension (d1) of the panel abutment rib 12.
[0024]
Similarly, as shown in FIG. 6, when the thickness of the joint flange 33 of the side sill panel 30 is set to a small value such as 2.9 mm, the mounting seat 11 protruding from the rear surface of the kicking plate 10 is provided. The height d1 of the panel abutment rib 12 formed on the panel facing surface 11a is set to be relatively high. Even at this time, the total thickness A of the iron clip 20 mounting portion is equal to the plate thickness (2.9 mm) of the joining flange 33. ) + Plate thickness of the mounting seat 11 (1.3 mm) + height dimension (d1) of the panel abutment rib 12, and the total thickness A of the mounting portion of the iron clip 20 shown in FIGS. 5 and 6 is the same dimension. Thus, the height dimension d1 of the panel abutment rib 12 is adjusted.
[0025]
Therefore, even if the thickness of the joining flange 33 in the side sill panel 30 is extremely different from 2.9 to 4.8 mm, the panel abutting rib 12 protruding from the panel facing surface 11a of the mounting seat 11 is provided. By adjusting the height dimension d1, the insertion force and pulling force of the iron clip 20 can be kept constant. This is because when the kicking plate 10 is attached to the side sill panel 30 via the iron clip 20, the pressing force required for the attachment is always constant, and the external force required for detaching when removing the kicking plate 10 from the side sill panel 30 is also constant. Therefore, it is necessary to prepare a plurality of iron clips 20 having different specifications by making it possible to ensure a smooth mounting force and a reliable mounting strength and to use a common iron clip 20. In addition, the cost is not increased, and the erroneous attachment of the iron clip 20 can be prevented.
[0026]
Next, FIGS. 7 and 8 show a modification of the mounting seat 11 according to the present invention. FIG. 7 shows the panel contact flange 13 on both sides of the mounting seat 11 of the kicking plate 10 toward the joint flange 33. By forming the mounting seat 11 in a substantially U-shaped cross section and adjusting the height dimension (indicated by d2 in FIG. 7) of the panel abutting flanges 13 on both sides, the joining in the side sill panel 30 is performed. The configuration corresponds to the change in the plate thickness of the flange 33.
[0027]
Similarly, as shown in FIG. 8, panel contact flanges 14 are formed on both sides of the kicking plate 10 so as to come into contact with the joint flanges 33 of the side sill panels 30, and the mounting seat 11 has a convex cross section. Also in this case, the difference in the thickness specification of the joining flange 33 in the side sill panel 30 can be absorbed by adjusting the height dimension of the flange 14 indicated by d3 in FIG.
[0028]
In the embodiment described above, the kicking plate 10 is applied to the side sill panel 30 positioned at the lower edge of the door opening via the iron clip 20 having a substantially S-shaped cross section. It goes without saying that the present invention can be applied to any structure that is composed of a synthetic resin molded body such as a side or a pillar garnish and is attached to a vehicle body flange via an iron clip on an attachment seat provided on the back side.
[0029]
【The invention's effect】
As described above, the mounting structure for an automotive interior part according to the present invention has a mounting seat integrally formed on the back surface of the interior part made of a synthetic resin molded body, and an iron clip having a substantially S-shaped cross section is mounted on the mounting seat. Then, when inserting and fixing the iron clip to the joint flange of the vehicle body panel, a panel abutment rib or panel abutment flange is provided on the joint flange facing surface of the mounting seat, and the dimensions of the panel abutment rib and the panel abutment flange are adjusted. Therefore, even if there is a change in the thickness of the joint flange due to the difference in specifications, the insertion force and pull-out force of the iron clip can always be maintained constant. A smooth mounting operation can be expected, and there is an effect that a certain mounting strength can be ensured without being unintentionally detached from the panel.
[0030]
Furthermore, even if there is a difference in the plate thickness specification of the joining flange, it is not necessary to set the specification difference of the iron clip, and the iron clip can be shared.
