Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular lamp such as a rear combination lamp or a vehicular device such as a rear finisher having a lens attached to a housing, and in particular, the appearance of the outer surface of the housing is improved. The present invention relates to a vehicle device.

[0002]

2. Description of the Related Art A conventional vehicle device of this type will be described with reference to FIGS. This example describes a rear combination lamp. In the figure, A is a rear combination lamp. The rear combination lamps A are mounted on the left and right sides of the rear portion of the vehicle body C of the automobile. B is a rear finisher. The rear finisher B is mounted on the vertical portion of the door D of the rear trunk of the automobile, which is in the middle of the left and right rear combination lamps A. The rear combination lamp A comprises a housing 1 and a lens 2.
The housing 1 is provided with an opening on the front surface and is made of synthetic resin, and the reflecting surface 12 is integrally provided on the inner surface thereof, or a separate reflector (not shown) is provided on the inner surface thereof. Or A recess 10 is provided on the entire periphery of the front opening of the housing 1. The recess 10 includes an outer wall portion 11, an inner wall portion 13, and a bottom portion 14. A convex portion 15 for blindfolding is integrally projected from a bottom portion 14 of the concave portion 10 of the housing 1. The lens 2 is made of synthetic resin and is light transmissive. An appropriate prism is engraved on the inner surface of the lens 2, and the leg portion 20 is integrally projected on the entire peripheral edge of the inner surface. The lens 2 is attached to the housing 1 by bonding the leg 20 of the lens 2 to the recess 10 of the housing 1 by hot melt (not shown) or by sealing with a packing. As a result, the lamp chamber 22 is defined by the housing 1 and the lens 2. A light source bulb (not shown) is arranged in the lamp chamber 22. By turning on the light source bulb, light from the light source bulb passes through the lens 2 and is radiated to the outside in a predetermined light distribution pattern.

The rear finisher B has a housing 4 made of synthetic resin and a lens 4 made of synthetic resin similarly mounted on the front opening. In the figure, 5 is a molding interposed between the rear combination lamp A and the vehicle body C.

[0004]

However, in the above-mentioned conventional vehicle device (rear combination lamp), the outer wall portion 11 and the inner wall portion 1 are formed in the front opening of the housing 1.
Since the concave portion 10 formed of the bottom portion 3 and the bottom portion 14 is provided, the outer wall portion 1 of the concave portion 10 of the housing 1
The thickness of the portion where 1 and the bottom portion 14 intersect becomes thick. When the wall thickness of the resin molded product is increased, sink marks (recesses) are likely to occur on the outer surface of the resin molded product. Therefore, in the above-described conventional vehicle device, as shown by mesh hatching in FIG. 5, the thick portion of the recess 10 of the housing 1, that is, the portion where the outer wall portion 11 and the bottom portion 14 intersect each other. The sink mark (recess) 6 is likely to occur on the outer surface. If sink marks 6 are formed on the outer surface of the recess 10 of the housing 1, it is not preferable in appearance. Particularly, in the above-mentioned rear combination lamp, when the trunk door D is opened, the outer surface of the recess 10 of the housing 1 located inside the trunk is visible, so that the sinker 6 is formed on the outer surface of the recess 10 of the housing 1. If there is, there is a problem that it does not look good.

An object of the present invention is to provide a vehicle device in which the appearance of the outer surface of the housing is improved.

[0006]

According to the present invention, there is provided an outer surface of an outer wall of a recess of a housing at a location where the outer wall and the bottom intersect with each other, from an opening end surface of the outer wall to the location. It is characterized in that a step portion for reducing the wall thickness is provided.

[0007]

With the above-described structure, the present invention compares the wall thickness from the opening end surface of the outer wall portion of the recess of the housing to the portion where the outer wall portion and the bottom portion intersect with the conventional one. Can be thinned. As a result, sink marks are generated on the outer surface of the thick portion of the recess of the housing.
It can be pressed down as much as possible compared to the conventional one, and the appearance can be improved.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a vehicle device according to the present invention is shown in FIG.
2 and FIG. 2. This example describes a rear combination lamp. 3 and 4 in the figure
The same reference numerals denote the same items. In the figure, 7 is a step. The step portion 7 is provided on the outer surface of the outer wall portion 11 of the recess 10 of the housing 1 and in the middle of the wall thickness T of the bottom portion 14 at the location where the outer wall portion 11 and the bottom portion 14 intersect. Is. As a result, the recess 10 of the housing 1
In the outer wall portion 11, the wall thickness from the opening end surface of the outer wall portion 11 to the step portion 7 can be reduced. The step 7 may be provided on the entire circumference of the housing 1, or may be provided only on a portion visible when the trunk door D or the like is opened. Further, the width of the stepped portion 7 is, for example, about 0.5 to 1 mm.

Since the vehicular apparatus of the present invention in this embodiment has the above-described structure, the outer wall 11 of the recess 10 of the housing 1 is opened from the opening end face of the outer wall 11 to the outer wall 11 and the bottom. The wall thickness up to the point intersecting 14 can be reduced as compared with the conventional one.
As a result, it is possible to suppress the occurrence of sink marks on the outer surface of the thick portion of the recess 10 of the housing 1 as much as possible compared with the conventional one, and it is possible to improve the external appearance.

Further, in the vehicle device of the present invention, even if the thickness of the outer wall portion 11 of the recess 10 of the housing 1 is made thin, the step portion 7 provided on the outer surface of the outer wall portion 11 makes the outer side Since the wall portion 11 has rigidity, there is no particular problem.

Further, in the vehicle device of the present invention,
The degree of freedom in mold design, such as setting the gate opening of the mold, is increased.

Although the rear combination lamp has been described in this embodiment, the present invention can be applied to other vehicular lamps and vehicular devices such as a rear finisher.

[0013]

As is apparent from the above, the vehicular apparatus of the present invention is such that the outer wall portion of the outer wall portion of the recess of the housing intersects the outer wall portion and the bottom portion of the outer wall portion. Since the step portion for reducing the wall thickness from the opening end surface to the above-mentioned portion is provided, the outer wall portion and the bottom portion of the outer wall portion intersect the outer wall portion and the bottom portion in the outer wall portion of the recess of the housing. The wall thickness up to the point can be made thinner than the conventional one. As a result, it is possible to suppress the occurrence of sink marks on the outer surface of the thick portion of the recess of the housing as compared with the conventional one, and it is possible to improve the appearance.
