Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling structure of a vehicle interior lamp such as a map lamp or a room lamp of a vehicle,
The present invention relates to a roof lining provided with a vehicle interior lamp in order to perform the assembly structure.

[0002]

2. Description of the Related Art In the production and assembly process of a vehicle, when indoor lamps such as map lamps and room lamps are assembled on a roof, conventionally, the following two methods have been used. (1) At the opening of the roof lining attached to the body (roof panel), the wiring provided along the inside of the roof panel is connected to the lamp housing by male and female couplers, and then the lamp housing is tapped on the roof panel. After that, the lens is attached to the lamp housing by inserting a nail. (2) Similarly, the coupler connection is made, and the lamp housing to which the lens is fixed is attached one-touch to the opening lined with the roof lining reinforcing plate by inserting claws or using clips.

[0003]

However, in the above method (1), the workability is poor, so that a burden is imposed on the operator. In addition, a dimension error or the roof lining is pushed up after the mounting, so that the opening of the roof lining is opened. There is a problem that a gap is generated between the lamp housing and the lamp housing, and the appearance deteriorates. As a countermeasure, a cushion or the like is attached to the back surface of the lining. Also, since there is no direct positioning method to the roof lining,
A step (gap) in the left-right direction occurs, and the appearance becomes poor. Further, the method (2) has a problem in that the workability is good, but a metal or resin reinforcing plate for lining the opening of the roof lining is required, so that the cost is high. When the roof lining was removed for repair, the lamp housing had to be removed and the coupler had to be removed, which was a tedious operation. Further, conventionally, it is necessary to prepare a dedicated lamp component corresponding to the difference in the model of the vehicle, so that the versatility as the lamp component cannot be achieved. In addition, conventionally, when changing the image of the lamp section, all changes including the housing side have been required.

Accordingly, an object of the present invention is to reduce the man-hours, improve workability and reduce the burden on workers by installing the indoor lamp when the roof lining is mounted on the vehicle body. The interior lamps for vehicles are designed to improve the appearance by eliminating the gap between the opening of the roof lining and the lamp housing, improve the appearance, and eliminate the need for reinforcing members. It is to provide an assembly structure. Another object of the present invention is to provide a roof lining provided with a vehicle interior lamp in order to perform such an assembly structure.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the invention according to claim 1 is an assembling structure of an interior lamp for a vehicle, wherein the opening for installing a lamp in a roof lining to be mounted on a roof panel.

By means of the coupler, the lamp housing can be easily fixed to the roof panel simultaneously with the electrical connection, and the lamp housing can be easily detached. Then, it is desirable to use such coupler (ramp) portion attachment as a reference (position) for roof lining attachment.

According to a third aspect of the present invention, there is provided an assembling structure of the vehicle interior lamp according to the first aspect, wherein the lamp housing is fixed to the roof panel by engaging concave and convex. . For example, as the uneven engagement,
The relationship between the claw and the hole is given, but other configurations may be used, and the installation relationship may be either.

According to the third aspect of the present invention, the lamp housing according to the first aspect is fixed to the roof panel by the concave and convex engagement, so that the lamp housing can be easily fixed to the roof panel. The lamp housing can be easily attached and detached.

According to a fourth aspect of the present invention, there is provided a roof lining having an opening for assembling a lamp and mounted on a roof panel, wherein the lamp is provided around the opening for assembling the lamp. It is characterized in that it is sandwiched between a housing and a lens assembled to the lamp housing.

As described above, according to the fourth aspect of the present invention, since the roof lining has the periphery of the opening sandwiched between the lamp housing and the lens, the wiring on the roof panel side and the wiring of the lamp are connected. At the same time as installing the roof lining on the car body, the lamp is also assembled.

Thus, the lamp housing 3 is fixed to the roof panel 1. Although not shown, the wiring provided on the roof panel 1 and the wiring of the lamp 31 are simultaneously connected by a coupler. Although the lower surface of the lamp housing 3 is simplified in the illustrated example as a uniform surface, the lamp housing 3 includes a lamp 31, a locking hole 34, and a switch knob 35, as in the above-described embodiment.

FIG. 3 is a perspective view showing a method of increasing the diversion rate using the lamp housing 3, and FIG. 4 is a longitudinal sectional view of a main part thereof. That is, in this embodiment, as shown, an insertion hole 37 is formed in the lower surface of the lamp housing 3 and a contact claw 38 for additional connection is provided on a side surface of the male coupler 32. A coupler 52 provided on a cord 51 from a roof lamp (not shown) provided at the center of the roof between the front seat and the rear seat is inserted into the insertion hole 37 on the lower surface of the lamp housing 3 as shown in FIG. As described above, the engaging portion 53 provided on the side surface of the coupler 52 is fitted and connected to the engaging claw 38 on the side surface of the male coupler 32 of the lamp housing 3. In this case, as shown, the lower surface of the coupler 51 is held by the periphery of the insertion hole 37 on the lower surface of the lamp housing 3. As described above, power can be supplied to the roof lamp using the map lamp.

FIG. 5 is a perspective view of a main part showing another method of increasing the diversion rate using the lamp housing 3. In this embodiment, as shown, the male coupler 32 of the lamp housing 3 is enlarged. The power outlet 32a has pin holes 39, 39, 39, 39 formed in the lower surface of the lamp housing 3 corresponding to the power outlet 32a. Such a pin hole 39 on the lower surface of the lamp housing 3,
39, 39, 39 have contact pins 54, 54, 5 provided on a cord 51 from a roof lamp as shown.
4, 54 are inserted respectively.

In the above embodiment, a map lamp is used as an indoor lamp, but the present invention is not limited to this, and a room lamp may be used. In case of room lamp, lens 4 for lamp replacement
Is removed, the lens mounting recess 22 of the roof lining 2 is removed.
Although the portion including hangs down a little, the lamp replacement operation can be performed without any trouble, and the lens 4 can be re-mounted later. In addition, the shapes of the lamp housing and the lens are also arbitrary, and it goes without saying that specific detailed structures and the like can be appropriately changed.
