Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a vehicle panel member such as a kicking plate.
[0002]
[Prior art]
Conventionally, many panel members are used as interior materials in automobiles.
[0003]
Many of these panel members have been devised in order to facilitate assembly.
[0004]
For example, “Automobile interior parts mounting structure” described in Japanese Utility Model Laid-Open No. 5-56531 enhances the rigidity of the flange part by extending an extension piece formed from the clip mounting seat along the flange part of the interior part. At the same time, a rib-like protrusion is provided integrally with the extension piece, and the end of the protrusion is fitted into the locking hole of the vehicle body panel so that the flange portion of the interior part and the vehicle body panel are integrated. It is configured.
[0005]
[Problems to be solved by the invention]
However, if the height of the protrusion is lower than the tip of the clip attached to the clip mounting seat as in the mounting structure of the above publication, first insert the tip of the clip into the mounting hole of the vehicle body panel, and then attach the tip of the protrusion. The projection does not function as a guide when the clip end is inserted into the mounting hole because it is inserted into the locking hole of the vehicle body panel. As a result, it takes time and effort to insert the clip end into the mounting hole. In addition to poor efficiency, the clip is prone to plastic deformation, which causes problems such as excessive force applied during assembly.
[0006]
Also, since multiple clips are usually attached to interior parts, the work of aligning and inserting these clips into multiple mounting holes on the body panel at the same time is complicated, and many different clips are used. Therefore, there is a problem that the cost of parts increases.
[0007]
On the other hand, if the clip is provided integrally with the interior part, the cost of the interior part can be reduced, but it is difficult to select a material that can achieve both the clip function and the interior part function. This reduces the holding power of the interior parts, and when some clips are inserted into multiple mounting holes at the same time and excessive force is applied to some of the clips, some of the clips become white. Since it loses its elastic force, there is a problem that the mounting strength of interior parts cannot be secured.
[0008]
The present invention has been made in order to improve such conventional problems, and it is an object of the present invention to provide a mounting structure for a vehicle panel member that allows easy mounting of the panel member and can secure sufficient mounting strength. It is.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the vehicle panel member mounting structure of the present invention is a vehicle panel member mounting structure in which a panel member, which is a vehicle interior material, is mounted to a vehicle body panel by a plurality of mounting means. Means are provided in the panel member and elastically engageable with the opening edge of the mounting hole formed in the vehicle body panel; together consist high guide portion height, the guide portion, when the locking claw is locked in the locking edge of the mounting hole, to form a guide surface that urges the locking pawl in the locking direction And the guide surface is formed on the first guide surface having a narrow front end side (small cross-sectional area) and the second guide surface having a base end side wide (large cross-sectional area), A third gas connected between the first guide surface and the second guide surface. Forming a de surface so as to be inclined from the distal side toward the proximal end side, wherein the second guide surface and the locking claws were both attached to the mounting hole.
[0010]
With the above configuration, the guide portion having a height higher than that of the locking claw can be first inserted into the mounting hole of the vehicle body panel, and the positioning of the locking claw and the mounting hole of the vehicle body panel can be performed by the guide portion. Even when the member is attached to the vehicle body panel by a plurality of attachment means, complicated alignment work is not required, so that the work efficiency during assembly is greatly improved and the locking claw is engaged by the guide surface provided in the guide portion. Since it is urged in the stop direction, there is no backlash between the panel member and the vehicle body panel.
[0011]
In addition, since the panel member is locked to the vehicle body panel by the locking claw provided on the panel member, there is no need for a clip as in the conventional mounting means, and this reduces the number of parts. Cost can be reduced, and elasticity can be imparted to the locking claw without impairing the function of the panel member, so that the material used for the panel member can be easily selected.
[0013]
In addition, since the tip of the guide portion can be easily inserted into the mounting hole of the vehicle body panel by the above configuration, the positioning of the mounting means and the mounting hole of the vehicle body panel can be achieved even if a large number of mounting means are provided on the panel member. Can be done easily.
[0014]
In order to achieve the object, the vehicle panel member mounting structure of the present invention is such that the elastic deformation amount of the guide portion is regulated by the locking portion so as not to exceed the elastic limit.
[0015]
With the above configuration, when the panel member is attached to the vehicle body panel, even if an unreasonable force is applied to the locking claw, the guide portion regulates the whitening of the locking claw, so that sufficient mounting strength of the panel member is ensured. be able to.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment in which the present invention is applied to a panel member such as a kicking plate will be described in detail with reference to the drawings.
[0017]
A panel member 1 such as a kicking plate is attached to a vehicle body panel 2 such as a step provided at the doorway of the vehicle body, and as shown in FIG. The arc-shaped portions 1b are connected to each other, and are integrally formed of a resin having wear resistance, for example, a talc-containing polypropylene (PP-C) resin.
[0018]
The side edge 1c of the large arc-shaped portion 1a is bent obliquely downward so that it can be inserted into a gap (not shown) in the interior material covering the floor surface in the vehicle compartment, and the side of the small arc-shaped portion 1b The edge extends downward along the vertical portion 2 a of the vehicle body panel 2.
[0019]
A plurality of mounting holes 2c are formed at intervals in the longitudinal direction at corners formed by the vertical portion 2a and the horizontal portion 2b of the vehicle body panel 2, and the small arc-shaped portion 1b of the panel member 1 is formed. On the back surface, a mounting means 3 that engages with the mounting holes 2c is projected.
[0020]
The attachment means 3 is composed of a hook-shaped locking claw 3a that engages with the opening edge 2e of the attachment hole 2c from below when it is inserted into the attachment hole 2c of the vehicle body panel 2, and a guide portion 3b. When the panel member 1 is molded, it is integrally molded and the locking claw 3a has elasticity in the direction of the guide portion 3b.
[0021]
As shown in FIG. 1, the locking claw 3a of the attachment means 3 is formed with an inclined surface 3c having a small inclination on the tip side and an inclined surface 3d having a large inclination on the base side, and these inclined surfaces 3c, 3d A flat top 3e is formed in the continuous portion.
[0022]
Moreover, the guide part 3b of the attachment means 3 consists of the rib part 3f whose height is higher than the latching claw 3a, and the reinforcement rib 3g protrudingly provided by the both sides | surfaces of the rib part 3f.
[0023]
The guide portion 3b guides the locking claw 3a to the mounting hole 2c when the locking claw 3a of the mounting means 3 is fitted into the mounting hole 2c of the vehicle body panel 2, and the tip portion is formed in a small arc shape. In addition, the side edge facing the locking claw 3a is formed substantially parallel to the locking claw 3a, and guide surfaces 3h, 3i, 3j are formed on the opposite side edge.
[0024]
The guide portion 3b is narrow at the distal end (small cross-sectional area) and wide at the proximal end (large cross-sectional area), and is engaged with the side edge on the distal end side and the side edge on the proximal end side. Guide surfaces 3h and 3j are formed so as to be substantially parallel to the side edge facing the claw 3a, and a guide surface 3i continuously connecting between the guide surfaces 3h and 3j is inclined from the distal end side to the proximal end side at a substantially intermediate portion. It is formed to do.
[0025]
Next, the operation of the vehicle panel member mounting structure constructed as described above will be described with reference to FIGS.
[0026]
In attaching the panel member 1 to the vehicle body panel 2, first, the attachment means 3 projecting from the back surface of the panel member 1 is positioned above the plurality of attachment holes 2 c formed in the vehicle body panel 2. In this state, the panel member 1 is lowered in the direction of the arrow A in FIG. 3, and the tip of the guide portion 3b is inserted into the mounting hole 2c as shown in FIG. 3, but the guide portion 3b has a height in advance with respect to the locking claw 3a. In this state, the tip of the locking claw 3a does not reach the mounting hole 2c, and the guide portion 3b is inserted into the mounting hole 2c first, so that the plurality of guide portions 3b are attached to the plurality of mounting portions. The work of simultaneously inserting into the holes 2c can be easily performed.
[0027]
Next, from this state, the panel member 1 is pulled in the direction indicated by the arrow B in FIG. 3, and the leading end guide surface 3h is brought into contact with the vertical edge 2a side opening edge 2d of the vehicle body panel 2, thereby 4 is positioned in the mounting hole 2c, and when the panel member 1 is further pushed down in this state, the inclined surface 3c on the front end side of the locking claw 3a is pressed against the opening edge 2d on the horizontal part 2b side of the vehicle body panel 2, and FIG. As shown in FIG. 3, the guide surface 3i that is elastically deformed toward the guide portion 3b and reaches the opening edge 2d on the vertical portion 2a side of the vehicle body panel 2 is inclined.
[0028]
When the panel member 1 is further pushed down in this state, the top 3e of the locking claw 3a exceeds the vertical edge 2a side opening edge 2d of the vehicle body panel 2, and at the same time, the guide surface 3j of the guide 3b is shown in FIG. Since the vertical edge 2a side opening edge 2d of the panel 2 is reached, the panel 2 can be attached to the mounting hole 2c of the vehicle body panel 2 without backlash.
[0029]
Further, after the panel member 1 is attached, the inclined surface 3d having a large inclination of the locking claw 3a comes into contact with the opening edge 2d of the horizontal portion 2b of the vehicle body panel 2 from below, so that the panel member 1 is always drawn toward the lower hole. Since the guide surface 3j of the locking portion 3b urges the locking claw 3a in the locking direction, there is no backlash between the panel member 1 and the vehicle body panel 2.
[0030]
On the other hand, FIGS. 6 and 7 show modifications of the attachment means 3, and these modifications will be described next.
[0031]
In the modification shown in FIG. 6, the distance between the locking claw 3a and the guide portion 3b is narrowed, and the amount of deformation of the locking claw 3a is regulated by the guide portion 3b. When the engaging claw 3a is deformed beyond the elastic limit when it is inserted into the hole 2c, so-called whitening occurs in which the resin material becomes cloudy and loses elasticity. In particular, in a composite material with improved resistance to scratches (such as PP-C described above), whitening due to bending may easily occur.
[0032]
In order to prevent such whitening of the locking claw 3a, in the modification shown in FIG. 6, the locking claw 3a is prevented from being deformed beyond the elastic limit by the guide portion 3b. When the member 1 is attached, the locking claw 3a is not whitened, so that a predetermined attachment strength can be ensured.
[0033]
Further, in the modification shown in FIG. 7, the guide portion 3b is formed in a cylindrical shape, and the guide surface 3k that is inclined at the distal end portion is formed, thereby reducing the sectional area on the distal end side and reducing the sectional area on the proximal end side. It is enlarged and functions similar to those of the above embodiment can be obtained.
[0034]
In the above-described embodiment, the case where the panel member 1 is a kicking plate has been described. However, the present invention can be applied to panel-like interior materials in general.
[0035]
【The invention's effect】
As described in detail above, the present invention provides a plurality of attachment means for attaching a panel member, which is an interior material of a vehicle, to a vehicle body panel, elastically provided at the opening edge of an attachment hole provided in the panel member and drilled in the vehicle body panel. And a guide portion that is erected in the vicinity of the engagement claw and that is higher than the engagement claw. Since the guide surface that urges the locking claw in the locking direction when locked to the stop edge is formed, the guide part that is higher than the locking claw is inserted into the mounting hole of the vehicle body panel first. The guide claw can be used to position the locking claw and the mounting hole of the vehicle body panel, which eliminates the need for complicated alignment work even when the panel member is mounted to the vehicle body panel by a plurality of mounting means. The work efficiency of While above, since the locking pawl by the guide surfaces provided on the guide portion is biased in the locking direction, nor backlash occurs between the panel member and the vehicle body panel.
[0036]
In addition, since the panel member is locked to the vehicle body panel by the locking claw provided on the panel member, there is no need for a clip as in the conventional mounting means, and this reduces the number of parts. Cost can be reduced, and elasticity can be imparted to the locking claw without impairing the function of the panel member, so that the material used for the panel member can be easily selected.
[0037]
In addition, the front end side of the guide part is made smaller, the cross section area on the base side is made larger, and the front end side and the base side are connected by an inclined guide surface. Since it can be inserted into the mounting hole of the vehicle body panel, the mounting member and the mounting hole of the vehicle body panel can be easily positioned even if the panel member is provided with a large number of mounting means, and the amount of elastic deformation of the locking claw However, when the panel member is attached to the vehicle body panel, even if an excessive force is applied to the locking claw, the guide portion controls the whitening of the locking claw. Therefore, the mounting strength of the panel member can be sufficiently ensured.
