Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to vehicle lighting equipment, and in particular, to a vehicle lighting device, such as a signal light, etc., a plurality of light chambers are arranged adjacent to each other, and the light chambers are partitioned with a light shielding plate. Regarding vehicle lighting equipment.

<Prior Art and its Problems> Conventionally, in signal lights and the like, vehicle lights have been known in which lens bodies of different colors are attached to an integral housing to define a plurality of light chambers.

For example, in the lamp shown in FIGS. 5 and 6, a stop lamp 2 on which a red lens body 1 is disposed and a back lamp 4 on which a white lens body 3 is disposed are integrally connected.

The lens bodies 1 and 3 are attached to a groove 5a formed on the outer circumference of the front surface of the housing 5 via a hot melt 6. In addition, a light shielding plate 9 is further arranged in the lamp chamber defined by this, and 2
Two lamp chambers 2a and 4a are defined. Lamp bulbs 7 and 8 are arranged in each of the lamp chambers 2a and 4a.

Incidentally, in such a vehicle lamp, the light shielding plate 9 is fixed by a set screw 10 that is tightened from the back side of the housing 5. That is, a boss portion 9a is provided at the base end of the light shielding plate 9, and a mounting hole is formed in this boss portion 9a. Further, a through hole is formed in the bottom wall of the housing 5 in correspondence with the mounting hole, and the light shielding plate 9 is fixed with a set screw 10 through this through hole.

Therefore, in this prior art, the set screw is required to hold the light shielding plate 9, which has the drawback of increasing the number of parts and increasing the cost.

In addition, in order to hold the light shielding plate 9, a set screw 10 is provided.
This has the drawback of requiring additional tightening work and complicating the process.

<Purpose of the invention> Therefore, an object of the present invention is to provide a vehicle lamp in which a light shielding plate can be easily attached without using screws.

<Structure of the invention> In other words, the vehicle lamp of the invention defines a light chamber by attaching a lens body to the front of the housing, and further defines a plurality of light chambers by arranging a light shielding plate within the light chamber. In the vehicle lamp, a protrusion is formed on the bottom of the housing to abut one side of the base end of the light shielding plate, and the light shielding plate is opposed to the protrusion with the light shielding plate in between. It is characterized by the formation of a spring piece that elastically presses the plate toward the protrusion.

<Description of Embodiment> As shown in FIG. 1, the vehicle lamp according to this embodiment has a pair of lens bodies 12 and 13 of different colors attached to the front opening of the housing 11.
The light chamber thus defined is further covered with a light shielding plate 20.
partition to define two lamp chambers 14a, 15a, and lamp bulbs 16, 17 are arranged in these lamp chambers 14a, 15a, for example, a stop lamp 14.
and a cross clamp 15.

The lens bodies 12 and 13 are in a state where they are joined to each other, and a band-shaped flange portion 18 provided at the peripheral edge portion is
It is inserted into a groove 11a formed on the outer periphery of the front surface of the housing 11, and is joined to the housing 11 by a hot melt agent 19 injected therein.

The light shielding plate 20 is made of synthetic resin or the like, and is formed to correspond to the shape of the boundary between the lamp chambers 14a, 15a, and prevents light from leaking between the lamp chambers 14a, 15a.

Further, a pair of parallel ribs 21 and 22 are formed on the bottom wall of the housing 11 along the base edge of the light shielding plate 20.
A part of the light shielding plate 22 is provided with a clamping part that clamps and holds the base end of the light shielding plate 20.

As shown in FIGS. 2 and 3, this clamping portion includes a cutout hole 11b formed in the bottom wall of the housing 11 between the ribs 21 and 22, and a protrusion formed in the inner wall of one of the ribs 21. 23, and a spring piece 24 connected to the other rib 22.

The protrusion 23 protrudes toward the other rib 22, and gradually protrudes from the tip to the base end of the rib 21.

Further, the cutout hole 11b is formed from the protruding end of the protrusion 23 to the base end of the rib 22.

Further, the spring piece 24 is connected to the upper edge of the rib 22 and curved toward the proximal end of the rib 22.
The tip is inserted into the notch hole 11b and is close to the protruding end of the protrusion 23.

In addition, this clamping part has a structure that can be integrally molded with the housing 11 by inserting a core mold into the notch hole 11b.

Further, as shown in FIG. 4, a protruding piece 20a is formed at the base end of the light shielding plate 20, and when this protruding piece 20a is inserted into the notch hole 11b, the protruding piece 20a is inserted into the notch hole 11b. It is designed to be held between the portion 23 and the spring piece 24. That is, when the protruding piece 20a is inserted into the notch hole 11b, the spring piece 24 is pushed by the protruding piece 20a and retreats, whereby the spring force of the spring piece 24 is applied to the protruding piece. 20a.

Further, as shown in FIG. 1, the light end portion of the light shielding plate 20 is formed with a flange portion 20b protruding from both sides in the thickness direction, and a joint portion of each of the lens bodies 12 and 13 is formed. It is in contact with the end surface of the thick portion 25 formed in the. Further, the flange portion 20
The both side edges of b further include the lens bodies 12 and 13.
It is bent to the side and covers the thick portion 25 from the inner surface.

In the vehicle lamp constructed as described above, the light shielding plate 20 is elastically clamped by the protrusion 23 of the clamping part and the spring piece 24, and its position is regulated in the thickness direction, and the light shielding plate 20 is held in this state. be done.

The light shielding plate 20 is fixed in the width direction by a regulating member (not shown) provided inside the housing 11.

<Effects of the Invention> According to the present invention, the light shielding plate can be held elastically within the lamp chamber extremely easily by the protrusion and the spring piece, and there is no need for screws for this purpose.
