DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a vehicle lamp such as a map lamp which mainly illuminates the inside of a vehicle.

[0002]

2. Description of the Related Art Conventionally, lamps mainly illuminating the interior of a vehicle include a room lamp and a map lamp, which are mounted on a roof lining provided inside a roof panel.

In recent years, many vehicles using a molded ceiling at the front of a roof line have been produced so that a sun visor or the like can be stored in a good shape. In the case of a molded ceiling, a lamp is conventionally formed as shown in FIG. It is attached to.

[0005] That is, in FIG. 5, reference numeral a denotes a roof panel of an automobile, and a molded ceiling c is attached to an inner front portion of the roof panel a so that a front end abuts on a front window b.

A lamp bracket e having a lamp mounting hole d is mounted inside the front roof rail g with a screw f inside the molded ceiling c. The lamp bracket e is opened to the molded ceiling c in the lamp mounting hole d. The lamp i is fitted to the molded ceiling c by fitting the lamp i through the lamp insertion hole h and engaging the locking piece j and the clip k provided on the lamp i with the line portion of the lamp mounting hole d. ing.

[0006]

In the above-described conventional lamp mounting structure, the lamp i is mounted on the lamp bracket e.

For this reason, if there is a variation in the lamp insertion hole h formed in the molded ceiling c with respect to the lamp mounting hole d formed in the lamp bracket e, if the flange m formed on the front side of the lamp i, In a lamp i having a small length L, the lamp insertion hole h cannot be covered by the flange m.
There is a problem that the mounting of the lamp i causes backlash and the lamp i falls off.

Further, since the mounting position of the lamp on the molded ceiling c is determined by the layout of the sun visor, the mounting of the lamp i using the lamp bracket e as in the prior art requires the manufacture of the lamp bracket e for each vehicle type. There was a problem that it had to be costly and costly.

The present invention has been made in order to solve such a conventional problem, and is easy to mount on a molded ceiling.
It is another object of the present invention to provide an automotive lamp mounting structure that can be mounted with common parts for each vehicle type.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, a lamp is fitted from a vehicle interior into a lamp mounting hole formed in a molded ceiling, and a molded ceiling is mounted on a pin standing upright on the lamp. The lamp is mounted on the molded ceiling by engaging a plate-shaped plate provided on the back side of the lamp and clamping the molded ceiling between the flange of the lamp and the plate.

[0011]

With the above structure, the lamp is mounted on the basis of the molded ceiling, so that the operation of mounting the lamp is facilitated, and there is no danger that the mounting of the lamp becomes uncertain due to dimensional variations or the like and the lamp is dropped off.

In addition, the plate can be used in common for all types of vehicles, and even if a large force is applied during lamp operation, the plate is received on a wide surface of the plate. Rigidity also increases.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS.

FIG. 1 is a perspective view of the upper surface of the molded ceiling, FIG. 2 is a sectional view taken along the line AA of FIG. 1, FIG. 3 is a sectional view taken along the line BB of FIG. 1, and FIG. It is a side view.

In these figures, reference numeral 1 denotes a molded ceiling constituting a front portion of a roof line, which is integrally formed of resin, and a skin 2 is attached to the inside surface of the vehicle by means such as adhesion.

On the inner side surface of the molded ceiling 1 are formed two left and right recesses 1a for storing a sun visor (not shown), and a lamp 3 such as a map lamp is provided between these recesses 1a. A lamp mounting hole 1b for mounting is opened.

The lamp 3 has a structure in which a flange 3a larger than the lamp mounting hole 1b is provided on the inner side of the vehicle.
On the upper surface of the flange 3a, a plurality of, for example, four pins 3b are provided.
Are provided upright at intervals in the front-rear and left-right directions.
Are formed so that the pin holes 4a of the plate 4 can be engaged with these small diameter portions 3c.

The plate 4 is made of a plate material which is sufficiently larger than the lamp mounting hole 1b, and has a lamp 3 at its center.
The through hole 4b having a square hole shape that can be fitted therein is opened, and the above-mentioned pin hole 4a is protruded from the periphery of the through hole 3b so as to match the pin 3b of the lamp 3.

The pins 3b are inserted into the pin holes 4a.
A notch 4c having a width slightly larger than the diameter of the small diameter portion 3c is formed in the same direction of each pin hole 4a so that the small diameter portion 3c can be fitted.

As shown in FIG. 4, the plate 4 has a flat lower surface, and a reinforcing bead 4d is formed at both ends of the upper surface so as to be common to each vehicle type. I have.

In FIG. 1, reference numeral 5 denotes a harness for supplying electricity to the lamp 3, which is wired along the back side of the molded ceiling 1 and is fixed to the molded ceiling 1 by a tape 6.

Next, the operation of attaching the lamp 3 to the molded ceiling 1 will be described. First, the lamp 3 is fitted from the inside of the molded ceiling 1 on the vehicle side, and then the plate 4 is positioned on the back side of the molded ceiling 1. Notch 4 of plate 4 in small diameter portion 3c of pin 3b
Match c.

In this state, the plate 4 is slid forward to fit the pin hole 4a of the plate 4 into the small diameter portion 3c of the pin 3b. The inside of the molded ceiling 1 is formed by the flange 3a of the lamp 3. The lamp 3 can be attached to the molded ceiling 1 by sandwiching the back side of the ceiling 1 with the plate 4.

[0024]

According to the present invention, as described in detail above, the lamp is mounted in the lamp mounting hole of the molded ceiling using the plate, so that the conventional lamp bracket is unnecessary and the molded ceiling is used as a reference. Since the lamp can be mounted, it is possible to solve the problem that the mounting of the lamp becomes uncertain due to the variation in the dimensions of the lamp bracket and the molded ceiling, and the lamp falls off.

Also, since the lamp is supported on the wide surface of the plate, even if a large force is applied to the lamp during lamp operation, the lamp is received by the wide surface of the molded ceiling, thereby increasing the rigidity of the molded ceiling and Since the plate can be used in common for each vehicle type, the cost can be significantly reduced as compared with the conventional case where a lamp bracket is manufactured for each vehicle type.

Moreover, since the harness for supplying electricity to the lamp can be wired along the back surface of the molded ceiling,
The number of wiring steps can be reduced.
