BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel vehicle lamp. More specifically, the present invention relates to a vehicle lighting device having a lamp body and a lens covering an opening surface of the lamp body, and more particularly to a vehicle lighting device arranged on the same surface as a surface on which a garnish panel is arranged on a vehicle body surface, An object of the present invention is to provide a novel vehicle lighting device capable of mounting a lens using a garnish panel, reducing the number of parts and assembling man-hours, and enhancing the makeup effect of the garnish panel.

[0002]

2. Description of the Related Art Many vehicle lamps include a lamp body having an open front surface, a lens fixed to the lamp body so as to cover the opening surface, and a lamp space defined by the lamp body and the lens. And the like.

In recent years, there has been a strong demand for an aesthetic appearance of an automobile. For this reason, a garnish panel may be intentionally provided on the surface of a vehicle body, for example, at the center of the rear surface of a passenger automobile.

FIG. 11 shows an example of an arrangement of a garnish panel and a rear signal light arranged on the rear surface of a vehicle body.

In FIG. 1, reference numeral a denotes a rear surface of a vehicle body, and a garnish panel c having a horizontally long rectangular shape is disposed in a relatively shallow recess b formed substantially in the center of the rear surface a in a storage shape. The license plate e is fitted in a relatively large window d formed in the garnish panel c.

Reference numeral f denotes a rear signal lamp, for example, a backup lamp, which is disposed on the side of the garnish panel c, and has a concave lamp body g having an open front surface, and is fixed to the lamp body g so as to cover the opening surface. Lens h and a bulb i supported by a bulb mounting portion formed at the center of the rear end of the lamp body g, and the front surface of the lens h is located in substantially the same plane as the front surface of the garnish panel c. To be supported by the rear part a of the vehicle body.

Thus, the periphery of the license plate e in the rear part a of the vehicle body is covered with the garnish panel c, and a sense of discomfort with the lamp f adjacent thereto is reduced.

Generally, the garnish panel c is formed of a synthetic resin having a desired color, or is coated with a desired color after the formation.

[0009]

However, according to such an arrangement of the garnish panel c and the lamp f, there is inevitably some gap between the garnish panel c and the lamp f, and this gap is unexpectedly large. Since it is conspicuous, there is a problem that the makeup effect provided by the garnish panel c is not sufficiently exhibited.

Although the details of the lamp f are omitted in the drawings, the lamp f is actually constructed by assembling a large number of parts, so that the number of parts is large and the assembling is troublesome. In particular, the connection between the lamp body g and the lens h is extremely troublesome during the assembling operation.

[0011]

Therefore, in order to solve the above-mentioned problems, the vehicle lamp of the present invention is arranged inside a garnish panel attached to the surface of the vehicle body, and the lamp body or the lamp body is supported. Forming a mounting groove that opens forward on the periphery of the vehicle body side member, and forming a mounting ridge on the garnish panel that fits into the mounting groove,
The garnish panel is supported by the lamp body or the vehicle body-side member by fitting the mounting ridge into the installation groove,
The lens for covering the opening surface of the lamp body has a peripheral portion supported by the lamp body or the vehicle body side member and the garnish panel.

[0012]

Therefore, in the vehicle lighting device of the present invention, since the whole is located inside the garnish panel, there is no boundary between the garnish panel and the lighting device when the garnish panel is viewed from the front side. , A high design effect can be obtained. Then, by attaching the garnish panel to the lamp body or the vehicle body-side member from a state where the lens is positioned so as to cover the opening surface of the lamp body, the lens is held by the vehicle body-side member or the lamp body and the garnish panel. Special members and work for connecting the body and the lens can be omitted, and accordingly, the number of parts and the number of assembling steps of this kind of lamp can be reduced.

[0013]

Thus, the rear fog lamp 30 is constituted by the left lamp body 33, the substantially left half of the main lens 41 and the bulb 47, and the backup lamp 3 is constituted by the right lamp body 34, the sub lens 42 and the bulb 48.
1 is configured.

The entire rear combination lamp 5 is located inside the lamp cover 18b of the garnish panel 6.

The rear combination lamp 5 is constructed as described above, so that no special members and work are required for mounting the lens 40, and the entire combination lamp 5 is located inside the garnish panel 6. When viewed from the front, there is no boundary between the rear combination lamp 5 and the garnish panel 6, so that the appearance is clean.

[0058]

As is apparent from the above description, the vehicle lighting device of the present invention is disposed inside a part of a garnish panel attached to the surface of the vehicle body, and forms the lamp body and the opening surface of the lamp body. A vehicle lamp having a lens to be covered, wherein a mounting groove which opens forward is formed in a peripheral portion of a lamp body or a vehicle body-side member, and a mounting ridge which fits into the mounting groove is formed in a garnish panel. The rim of the lens is supported between the lamp body or the vehicle body side member and the garnish panel by fitting a mounting ridge of the garnish panel into the installation groove.

Therefore, in the vehicle lamp of the present invention, the whole is located inside the garnish panel.
When the garnish panel is viewed from the front side, there is no boundary between the garnish panel and the lamp, and a high design effect can be obtained. Then, by attaching the garnish panel to the lamp body or the vehicle body-side member from a state where the lens is positioned so as to cover the opening surface of the lamp body, the lens is held by the vehicle body-side member or the lamp body and the garnish panel. Special members and work for connecting the body and the lens can be omitted, and accordingly, the number of parts and the number of assembling steps of this kind of lamp can be reduced.

In the above embodiment, the lamp body is formed separately from the lamp housing, and the mounting ridge of the garnish panel is fitted into the installation groove formed in the lamp housing. When integrally formed with the housing or other vehicle body-side member, an installation groove may be provided in the lamp body of the vehicle body-side member or a peripheral portion thereof.

Further, in the above embodiment, a clamped portion is provided which protrudes outward from the outer peripheral edge of the lens, and the clamped portion is in contact with the front edge of the wall defining the mounting groove of the lamp housing and the garnish. Although the lens is supported by the lamp housing and the garnish panel by being sandwiched between the inner surfaces of the panel, the lens holding structure in the present invention is not limited to such a structure.

In addition, the structure and function of the lamp and the structure and shape of the garnish panel and other parts shown in the above embodiment are merely examples of the embodiment of the present invention, and are not limited thereto. The technical scope of the invention should not be construed as limiting.
