Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a vehicle lamp, and more particularly to a composite lamp in which a portion of the housing is partitioned.

[Conventional technology]

FIG. 2 shows the structure of a conventional lamp of this kind, in which a part of the housing 21 has a slit 21a.
A light-shielding plate 22 is inserted into this slit 21a and divided to form a section 23. A heat insulating plate 24 which also serves as a reflector is fixed within this section 23 with screws 25, and this section 23 is also independent. The lamp has the following functions.

[Problem to be Solved by the Invention] However, although the section 23 formed as described above generally has a small area, it cannot be used as a high-output light such as a side light that is turned on when a vehicle turns. For this reason, the heat insulating board 24 is indispensable.However, there are problems in that the installation using the screws 25 requires work in a narrow and deep position, which is an extremely complicated process, or the insulating board 24 cannot be used. The number of screws 25 is limited due to the narrowness, and the minimum required two screws cannot be used, resulting in insufficient mounting strength and problems such as play. The problem was to be solved.

[Means to solve the problem]

As a specific means to solve the above-mentioned conventional problems, the present invention has been developed for a vehicle in which a heat insulating plate that also serves as a semi-reflection plate is attached in a compartment divided by a light shielding plate inserted into a pair of slits in the housing. In the lamp, the housing is provided with a wall portion extending in a direction parallel to the light shielding plate on the compartment side of the slit and having a fitting recess formed on a surface on the slit side, and the wall portion is provided on the partition side of the slit, and the wall portion is provided with a fitting recess on a surface facing the slit. is provided with a tongue-like portion that fits into the fitting recess, and the tongue-like portion that fits into the fitting recess is held between the wall-like portion and the light shielding plate inserted into the slit. The above-mentioned conventional problems are solved by providing a structure for mounting a heat insulating plate for a vehicle lamp, which is characterized by the following.

【Example】

Next, the present invention will be explained in detail based on an embodiment shown in the drawings. 1 is a housing, and this housing 1 is provided with slits 1a, 1a similar to the conventional example, and has a structure in which a light shielding plate 2 is inserted and fixed. According to the invention, the housing 1 on the side of the partition 3 to be divided of both the slits 1a, 1a is extended to an appropriate length in the direction parallel to the light shielding plate 2, so that the wall-shaped portion 1b,
1b, and furthermore, fitting recesses 1 are provided on the surfaces of the wall portions 1b, 1b on the side of the slits 1a, 1a, respectively.
c, 1c are provided. Further, the heat insulating plate 4 is provided with a mounting hole 4a for a screw 5 similar to that of the conventional example, but at the same time, one end of the heat insulating plate 4 in contact with the light shielding plate 2 is provided with the fitting hole 4a. Tongue-shaped portions 4b, 4b are provided at positions and shapes corresponding to the recessed portions 1c, 1c. When attaching the light shielding plate 2 and the heat insulating plate 4 to the housing 1 thus constructed, the tongue-shaped portion 4b,
4b into the fitting recesses 1c, 1c, and then inserting the light shielding plate 2 into the slits 1a, 1a, the heat insulating plate 4 is fixed at a predetermined position in the housing 1. Perform fixation using 5. Note that this embodiment is intended to explain the gist of the present invention, and in actual implementation, means for fixing the housing 1 and the light-shielding plate 2 are naturally provided. Since this is not the gist of the article, its explanation will be omitted here.

[Effect]

In this way, in addition to fixing the heat insulating plate 4 with the screws 5, one end of the heat insulating plate 4 is clamped and fixed between the housing 1 and the light shielding plate 2, so even if the screw 5 is fixed at one point, rotation or play can be avoided. This will prevent this from occurring.

[Effect of the idea]

As explained above, the present invention has a mounting structure of a heat insulating plate with one end sandwiched between the housing and the light shielding plate, so even if only one screw is used for fixing, it is essentially fixed at two points. It provides the same mounting strength and backlash prevention effects as the
Furthermore, it also has the excellent effect of simplifying the assembly process and reducing costs.
