[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small component mounting structure for mounting a small component such as a step lamp in a door pocket or the like made of a PP resin molded body.

[0002]

2. Description of the Related Art For example, as shown in FIG. 10, a door pocket 2 made of a PP resin molded body or the like is mounted below a surface of a door trim 1, and further, the door pocket 2 has a foot portion of an occupant. A step lamp 3 is provided to illuminate the camera.

FIG. 1 shows a mounting structure of the step lamp 3.
As shown in FIG. 1, an opening 4 for fitting the step lamp 3 is formed in the door pocket 2. On both side edges of the opening 4, mounting flanges 5 extending in the mounting direction are integrally provided. Locking hole 6 provided in mounting flange 5
Locking pieces 7 projecting from both sides of the step lamp 3
, The step lamp 3 is attached to the opening 4 of the door pocket 2.

[0004]

As described above, conventionally, when the step lamp 3 is mounted on the door pocket 2, mounting flanges 5 are formed on both side edges of the opening 4 in the mounting direction.
Since the mounting flange 5 is formed integrally with the door pocket 2 by injection molding of a synthetic resin, it is necessary to set a draft angle of the angle α along the die-cutting direction indicated by the arrow A in FIG. When the step lamp 3 is engaged in the opening 4, a skip due to the draft angle occurs, causing a problem such as poor appearance and rattling.

Further, when the locking hole 6 is formed in the mounting flange 5, it is necessary to set the slide core in the injection molding die, which increases the cost of the die and causes the boss and the boss to slide in the sliding direction of the slide core. It has also been pointed out that a rib or the like cannot be set and the degree of freedom in modeling is restricted.

The present invention has been made in view of such circumstances, and the present invention relates to a small component mounting structure for mounting a small component in an opening formed in a PP resin molded body such as a door pocket. It is an object of the present invention to provide a mounting structure for small parts that can be formed with an inexpensive mold structure that does not require a slide core as a molding die, while improving appearance and improving mounting stability. I do.

[0007]

Means for Solving the Problems To achieve the above object, the present invention provides a small part mounting structure for fitting a small part into an opening formed in a PP resin molded body. At the edge, a mounting flange is integrally formed so as to be located on substantially the same plane as the PP resin molded body via a hinge portion, and the mounting flange is raised on the back surface side based on the hinge portion to form a PP resin molded body. Alternatively, the upright state of the mounting flange is maintained via a projection formed on the back surface of the mounting flange, and both side surfaces of the small component are sandwiched by the mounting flange.

[0008] Further, the mounting flange is characterized in that a locking hole is provided for engaging locking pieces provided on both side surfaces of the small component.

[0009]

As is apparent from the above configuration, the mounting flange formed on the same plane as the PP resin molded body so as to protrude into the opening from both side edges of the opening is operated to stand upright on the back side based on the hinge portion. For example, the mounting flange can be maintained in an upright state through the PP resin molded body or the projection formed on the back surface of the mounting flange, so that there is no need to set a conventional draft angle, and both sides of the mounting flange and the small component are not required. No skidding occurs between the surface and the surface.

Furthermore, by adjusting the shape and dimensions of the projection, the angle of the mounting flange can be arbitrarily adjusted, and the shape of the small component can be arbitrarily adjusted.

The mounting flange has PP on both sides of the opening.
Since it is molded on the same plane as the resin molded body, a slide core is not required when forming a locking hole in this mounting flange.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing a mounting structure of a small component according to the present invention.

FIGS. 1 to 5 show a first embodiment of the present invention, in which the present invention is applied to a structure in which a step lamp is mounted on a door pocket.

FIG. 1 is an overall perspective view showing a door pocket and a step lamp, FIGS. 2 to 4 are explanatory views showing an operation of mounting a step lamp which is a small component according to the present invention, and FIG. 6 to 9 are perspective views of a mounting flange showing a modification of the present invention.

First, in FIG. 1, a door pocket 11 made of a PP resin molded body is mounted below the surface of a door trim 10, and a step lamp 20 for illuminating a foot portion of an occupant is mounted on the door pocket 11. An opening 12 for fitting is provided.

Further, as shown in FIG. 2, mounting flanges 13 are integrally formed on both side edges (upper and lower in this embodiment) of the opening 12 so as to be able to stand upright on the back side based on the hinge portion 14, and the door 12 is provided. When the pocket 11 is formed, the mounting flange 13 is set so as to be located on the same plane as the door pocket 11.

As a result, there is no need to consider the draft angle required during molding, which is conventionally required.

Further, a projection such as a stopper rib 15 is integrally formed on the back surface of the mounting flange 13, and a rectangular locking hole 16 is formed in the center of the mounting flange 13.

Then, as shown in FIG. 3, each mounting flange 13 is rotated in the direction of the arrow based on the hinge portion 14 so that a stopper rib 15 integrally formed on the back surface of the mounting flange 13 has a door pocket. The mounting flange 13 is erected up to a position where it comes into contact with the back surface of the mounting 11.

Note that a boss may be used instead of the stopper rib 15, and the shape is not particularly limited as long as it is a projection. Further, the stopper rib 15 may be formed on the back surface of the door pocket 11, but in consideration of the case where sinks or the like occur,
It is desirable to form it on the back surface of the mounting flange 13.

Next, as shown in FIG. 4, the step lamp 20 is inserted into the opening 12 so that the both side surfaces 21 of the step lamp 20 are brought into sliding contact with the mounting flanges 13. The mounting of the step lamp 20 is completed by engaging the provided locking piece 22 with the locking hole 16 of the mounting flange 13.

At this time, if the end of the mounting flange 13 is expanded outward and the step lamp 20 is inserted, the mounting of the step lamp 20 is completed easily.

FIG. 5 shows a state in which a step lamp 20 is mounted in the opening 12 of the door pocket 11.
As described above, the draft angle is not set, the rising angle of the mounting flange 13 can be freely adjusted by the stopper rib 14, and both side surfaces 21 of the step lamp 20 can be sandwiched by the mounting flange 13 without any gap. For this reason, it is possible to prevent the occurrence of a squeeze caused by the die-cutting angle as in the related art, thereby improving the appearance and preventing rattling as much as possible.

Further, since the locking hole 16 can be formed by a general-purpose mold without using a slide core, the cost of the mold does not increase, and the ribs 17 and the like can be freely placed on the back surface of the door pocket 11. Can be set, and the degree of freedom in modeling is improved.

FIGS. 6 to 9 show a modification of the present invention. For example, as shown in FIG. The mounting flange 1
3 This is an example of measures taken to prevent sink marks on the surface.
In FIG. 7, an abutment flange 18 is provided substantially at the center rear surface of the mounting flange 13.

As shown in FIGS. 8 and 9, the mounting flange 13 and the contact flange 18 are formed so as to have a substantially L-shaped cross section, and the contact flange 18 is attached to the back surface of the door pocket 11. In this case, the shape of the mounting flange 13 can be maintained well, and thus there is an advantage that the mounting stability of the step lamp 20 is further improved.

In each of the above-described embodiments, the door pocket 1
Although the structure in which the step lamp 20 is mounted in the opening 12 has been described, the present invention can be applied to the case where a blind lid is mounted on the PP resin molded body, and the application is not particularly limited.

[0028]

As described above, the mounting structure for small parts according to the present invention has the following special effects.

(1) The mounting flange extending in the mounting direction of the small component is formed so as to be located on the same plane as the PP resin molded body, and it is not necessary to set the die-cutting angle. This has the effect of preventing the occurrence of gaps between small parts and good appearance, and preventing the occurrence of play and improving the mounting stability.

(2) The mounting flange is located on the same plane as the PP resin molded body at the time of molding, and is operated upright when small parts are mounted. When opening a hole, a conventional injection molding die can be used to form the locking hole without the need for a conventional slide core, which can significantly reduce the cost of the mold and lead to a reduction in product cost. It has the effect of doing.

(3) Since the conventional slide core is not required, the conventional problem that the boss, the rib, and the like cannot be set in the slide direction of the slide core can be effectively solved.
The boss, rib, etc. can be freely set on the back of the resin molded product,
This has the effect that the degree of freedom in modeling can be dramatically improved.
