Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a housing structure for a vehicle interior lamp, and more particularly to an improved housing structure in which the thickness of the mounting seat can be adjusted.

FIG. 1 shows the installation state of a general vehicle interior lamp, in which a housing 1 containing an interior light assembly 10 is shown.
2 is firmly fixed to a mounting panel 14 of the vehicle body, usually on the roof panel side, with screws 16 and 18. Then, the cover 20 is removably attached to the housing 12, and the assembly of the vehicle interior lamp is completed.

When the housing 12 is fixed, the housing 12
The end of the ceiling material 22 is treated by inserting and fixing the ceiling material 22 between the mounting panel 14, but due to the thickness of the ceiling material 22, the housing 12 and the mounting panel 1
A gap 100 is created between the housing 12 and the housing 12, resulting in problems such as poor tightening or deformation of the housing 12.

Therefore, in the past, a mounting seat was provided on the housing 12 to ensure reliable fixation by eliminating the gap 100. However, in recent years, many types of ceiling materials 22 have been used in vehicles, and their thicknesses vary considerably, from thin plates such as PVC to thick plates such as urethane and cloth. Therefore, the thickness and length of the mounting seat must be changed for each ceiling material, resulting in the disadvantage that many types of housings must be prepared.

The present invention has been devised in view of the above-mentioned conventional problems, and its purpose is to provide an improved housing structure that can be used in common with many types of ceiling materials of different thicknesses.

In order to achieve the above object, the present invention provides a housing structure for a vehicle interior lamp which has a built-in interior light and is fixed to a mounting panel of a vehicle body, in which an opening is provided in the vicinity of the mounting hole of the housing. A spacer part integrally formed with the housing is provided so as to be foldable at a hinge part, and the seat thickness of the mounting hole can be adjusted by folding back the spacer part.

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 2 shows a perspective view of a housing according to the present invention, in which a housing 12 made of plastic such as polypropylene is provided with two mounting holes 24 at both ends for fixing with screws to a mounting panel. There is. A characteristic feature of the present invention is that there are openings 2 in the vicinity of each of the mounting holes 24.
6 is provided, and a foldable spacer portion 28 is further provided within this opening portion 26.

Hereinafter, this main part will be explained in detail with reference to FIGS. 3 and 4, which are enlarged views. The opening 26 has a substantially square shape adjacent to the mounting hole 24, and its size is determined so as to facilitate folding back of the spacer portion 28, which will be described later, and to maintain sufficient strength of the housing 12. A spacer portion 28 is provided within the opening 26 and is integrally connected to the housing 12 by a hinge portion 30, and the spacer portion 28 can be folded back toward the mounting hole 24 by the hinge portion 30. The width and thickness of the hinge portion 30 are set small. In the embodiment, the spacer part 28 has a ring shape with a through hole 32 formed approximately in the center, and has a boss 34 on the opposite side from the hinge part 30, and the boss 34 is connected to the housing 1.
It can be engaged with an engagement hole 36 provided in 2.

The embodiment of the present invention has the above configuration, and its operation will be explained next.

The states shown in FIGS. 2, 3, and 4 show the usage state in which the mounting hole 24 has a short seat thickness, and the spacer portion 28 is accommodated in the opening 26 without being folded back. Therefore, the seat thickness length in this state is determined only by the plate thickness around the mounting hole 24 of the housing 12, and can be adapted to a thin plate ceiling material. At this time, since the spacer part 28 is located within the opening 26, it does not interfere with the work during fixing to the mounting panel, and it is not exposed even after fixing, so it does not deteriorate the appearance.

FIG. 5 shows a state in which the spacer part 28 is folded back from the hinge part 30, and the through hole 32 is connected to the mounting hole 28.
The boss 34 is fitted into the engagement hole 36 to fix the folded position of the spacer portion 28.

As is clear from FIG. 5, by folding back the spacer portion 28, the seat thickness of the mounting hole 24 increases by the thickness of the spacer portion 28, thereby providing a housing suitable for thick plate ceiling materials. can do.

As described above, by folding back the spacer portion 28, the seat thickness length of the mounting hole 24 can be adjusted to a plurality of types, and the interior lamp can be shared.

In addition, in the present invention, by providing a plurality of foldable spacer parts around the mounting hole, it becomes possible to adjust the seat thickness length in various ways by combining these spacer parts.

As explained above, according to the present invention, since the housing can be shared, parts management and manufacturing man-hours are simplified, and there is no need to incorporate washers etc. during assembly, making the work easier. , furthermore,
In conventional housings in which only the thickness of the mounting seat differs, it is difficult to identify parts when they are mixed in, but the present invention has the advantage that the difference in seat thickness can be confirmed by the presence or absence of folding.
