Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a vehicular lamp, and more specifically relates to a mounting structure for a vehicular lamp that expands or contracts thermally.

[Conventional technology]

Conventionally, as shown in FIG. 4, this type of lamp is fixed to a long lamp a and a lamp housing b with a metal fitting c and a screw d, and is attached to a body via the metal fitting c.

At this time, the screw holes d of the fasteners c disposed at both ends of the lamp housing b are made larger in consideration of the coefficient of thermal expansion and contraction of the long lamp a.

[Problem that the invention attempts to solve]

However, in the case of the above-described conventional mounting structure, there was a drawback that the coefficient of thermal expansion and contraction increased in proportion to the length of the long lamp, which could not be accommodated with ready-made screw holes. Furthermore, the screw holes of the fasteners attached to both ends of the long lamp are large, making positioning difficult and troublesome in the installation process.

Furthermore, during the installation work, the number of parts such as screws increases, resulting in poor work efficiency.

[Means for solving problems]

This invention was made to eliminate the above-mentioned conventional drawbacks.A lens body is attached to the front of a rectangular lamp housing consisting of an upper and lower plate, a side plate, and a back plate, and a recess is formed approximately in the center of the upper plate. At the same time, slide recesses longer than the recess are provided on both ends of the upper plate on both sides of the recess, and a long lamp is provided on the bottom plate with a recess corresponding to the positioning rail of the body; A fixing part having a screw hole is provided on the lower surface of the attachment part along the plate, and a presser part is provided at the upper end of the attachment part and extends along the upper plate in a direction opposite to the fixing part, and The tip of the presser part consists of a presser metal fitting with a protruding presser claw that fits into the recess, and since the presser claw slides in the slide recess in response to the thermal expansion and contraction of the long lamp, no screws are required. Both allow long lamp installation.
This eliminated the need to make large screw holes.

[Effect]

In this invention, the concave part of the bottom plate is attached to the positioning rail of the body, the presser claw of the presser metal fitting is fitted into the recess of the upper plate, and the presser claw of the presser metal fitting is slidably fixed to the sliding recess of the upper plate. I made it so that it would be done.

〔Example〕

Next, the present invention will be explained based on an embodiment shown in FIGS. 1 to 3.

In FIG. 2, which shows the installed state, and FIG. 1, which shows a partial cross section of the installed state, A in the figures indicates the entire long lamp. This elongated lamp A consists of a rectangular lamp housing 1 disposed on a body 2 and a lens body 13 tightly attached to the front surface of the lamp housing. Also lamp housing 1
consists of a top plate 3, a bottom plate 4, side plates 5, and a back plate 6. A light emitter 9 such as a light emitting diode is attached to a base 7 within the lamp housing 1.

A recess 41 is provided at a predetermined position of the bottom plate 4 in correspondence with the positioning rail 21 protruding from the body 2 . Further, the upper plate 3 is provided with a recess 10 approximately in the center, and on both sides of the recess 10 and near both ends of the upper plate 3, a groove width similar to that of the recess 10 is provided, and the length of the recess 10 is Longer slide recess 1
1 and 12 are provided.

Note that the recess 10 and the slide recess 11, 1
2 is formed by integral molding, press working, etc.

In the figure, reference numeral 14 denotes a holding fitting for attaching the long lamp A to the body 2;
A fixing part 16 is provided at the lower end of the extension part 15 along the back plate 6 and along the second surface of the body. A screw hole 18 is provided in the fixing part 16, and the fixing part 16 is fixed to the body 2 with a screw 17.

Further, a presser part 19 is extended along the upper plate 3, which is located at the upper end of the support part 15 and in the opposite direction to the fixing part 16. A presser claw 20 is provided to protrude.

The lengths of the presser claw 20, the recess 10, and the slide recesses 11 and 12 are determined based on the length of the long lamp A, taking into consideration the coefficient of thermal expansion, contraction, etc.

[Effect of idea]

According to the present invention, the recessed part of the bottom plate is attached to the positioning rail of the body, and the presser claw of the presser metal fitting is fitted into the recessed part of the upper plate to fix the central part of the elongated lamp to the body, and the upper plate slides. Since the presser claw of the presser metal fitting is slidably fixed in the recess, stress caused by thermal expansion and contraction of the elongated lamp can be avoided.

In particular, when a long lamp is extremely long, the expansion and contraction are large and cannot be accommodated by screw holes, but since the slide recess according to the present invention is provided with a sufficient margin, stress is eliminated. Furthermore, since the long lamp is fixed with the presser claw of the presser metal fitting, the number of screw parts is reduced and the installation work becomes easier. Furthermore, since the presser claws can be easily aligned with the recesses and the slide recesses, the installation work is also easy. Further, since the lamp housing recess and the slide recess are integrally molded or press-worked with the lamp housing and no holes are formed, there is no need to seal these parts, improving work efficiency.
