[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle lamp, and more particularly to a vehicle lamp having a drainage for discharging water that has entered the interior downward.

[0002]

[Prior art]

 Lamps for illuminating the front and generating various display signals are provided on the outer surface of the vehicle. In addition, such a lamp discharges water accumulated inside from the bottom and prevents water from entering from the outside.

That is, as shown in FIG. 5 and FIG. 6, a pair of protrusions 2 are formed on the front side of the lamp housing 1 along the outer peripheral portion thereof, and a holding groove 3 is formed between the protrusions 2. ing. A packing 4 is mounted in the holding groove 3. A rib 6 is formed on the back side of the lens 5 along the outer periphery of the lens 5, and is fitted into the holding groove 3 so as to be crimped to the packing 4.

Then, a substantially central portion of the lower portion of the rib 6 is cut out to form a cutout portion 7, and a part of the lower protrusion 2 in the lower portion of the lamp housing 1 is located directly below the cutout portion 7. A notch is formed as a notch 8 and the notch 7 and the notch 8 allow the water accumulated inside to be discharged downward as indicated by the arrow in FIG. Further, a relatively short horizontally long backflow preventing wall portion 9 is provided at a position below the ribs 6 and below the ribs 6, and the wall portion 9 prevents water from flowing backward from below. Was there.

[0005]

[Problems to be solved by the device]

 According to such a vehicular lamp, as shown in FIG. 6, water accumulated in the lamp is drained to the lower part by draining water including the cutout portion 7 and the cutout portion 8. Further, the backflow preventing wall portion 9 makes it possible to block water from below as shown in FIG.

However, as shown in FIG. 5, the backflow preventing wall portion 9 prevents water from entering the lamp housing 1 from an oblique direction through the drainage including the cutout portion 7 and the cutout portion 8. Could not be prevented. Therefore, there was a problem that it was not possible to prevent water from entering the lamp when running on a road surface that was raining or wet, or when washing a car.

The present invention has been made in view of such problems, and it is possible to prevent not only water from below but also water from flowing backward from an oblique direction. It is an object of the present invention to provide a vehicle lamp capable of more reliably preventing water from entering the lamp when traveling in the rain, traveling on a wet road surface or washing a vehicle.

[0008]

[Means for Solving the Problems]

 According to the present invention, a holding groove is formed on the front side of the lamp housing along the outer periphery thereof, and a packing is attached to the holding groove, and the rear side of the lens mounted on the front side of the lamp housing is extended along the outer circumference thereof. A rib is provided, the rib is fitted into the holding groove, the tip end thereof is crimped to the packing, and drainage is formed by a notch formed by notching a part of the lower side of the rib. The present invention relates to a vehicular lamp, characterized in that a backflow preventing wall portion, which is continuous with the rib, is provided below the rib so as to surround the drainage and below the rear surface of the lens.

[0009]

[Action]

 Water accumulated inside the lamp is discharged downward through a water drain consisting of a notch formed by notching a part of the lower part of the rib of the lens. Further, water from below or obliquely below is blocked by the backflow preventing wall portion, and water is prevented from entering the lamp housing through the drainage.

[0010]

【Example】

 FIG. 1 shows a vehicular lamp according to an embodiment of the present invention. The vehicular lamp is directly attached to an upper exterior panel 16 on the front side of a large vehicle. A mounting recess 17 is formed in a portion near the corner below the exterior panel 16, and a horizontally long opening 18 is formed in the recess 17. The lamp housing 19 can be mounted in the mounting recess 17. A lens 21 is mounted on the front side of the lamp housing 19 via a packing 20, and the lens 21 and the lamp housing 19 are both fastened together with the exterior panel 16 by two screws 22 from the front side. There is.

In particular, as shown in FIG. 2, two protrusions 25 and 26 are formed on the front surface side of the lamp housing 19 and on the outer peripheral portion thereof. A portion between the ridges 25 and 26 forms a holding groove 27, and the packing 20 is held in the holding groove 27. Moreover, the protrusions 26 are absent and the absent portions 28 are formed at two locations below the lamp housing 19.

On the other hand, on the back side of the lens 21, ribs 29 are formed along the outer peripheral portion thereof. The rib 29 is adapted to be fitted in the holding groove 27 of the lamp housing 19. Moreover, a substantially central portion of the lower side of the rib 29 is cut out to form a cutout portion 30. Moreover, a U-shaped backflow preventing wall portion 31 is continuously provided below the cutout portion 30 so as to be continuous with the rib 29.

In the above structure, the lamp housing 19, the packing 20, and the lens 21 are mounted in the mounting recess 17 of the exterior panel 16 on the front side of the vehicle. The screw 22 is screwed in from the front side of the lens 21 and screwed into the female screw hole of the exterior panel 16 to fix the lamp to the exterior panel 16. The vehicle lamp of this embodiment constitutes a speed indicator lamp, and the speed of the vehicle is lit step by step to notify that fact.

The water that has entered the lamp housing 19 is discharged to the lower part through the notch 30 of the rib 29 of the lens 21 shown in FIGS. 3 and 4. Moreover, water from below or obliquely below is blocked by the backflow preventing wall portion 31 provided so as to surround the notch portion 30 of the rib 29 of the lens 21, and thereby the lamp housing 19 is provided. It is designed to prevent water from entering inside. In particular, in this embodiment, the backflow preventing wall portion 31 is provided continuously with the rib 29, and the portions connected to the ribs 29 on both sides of the wall portion 31 are inserted through the pair of missing portions 28 of the ridge 26. The backflow prevention wall portion 31 prevents water from entering the lamp housing 19 from the side.

According to such a vehicle lamp, water can enter the lamp housing 19 even when traveling on a wet road surface, traveling in the rain, or washing a vehicle. It will be possible to provide a highly waterproof vehicle lamp.

[0016]

[Effect of device]

 As described above, according to the present invention, the lens is a lower part on the back side so as to surround the drainage which is formed by notching a part of the lower side of the rib, and the backflow is continuous with the rib under the rib. A prevention wall is provided. Therefore, such a backflow prevention wall can prevent water from entering the lamp housing not only from below but also from the side, and when driving on a wet road surface or in the rain or when washing a car. Even in this case, it becomes possible to prevent water from entering the lamp housing.
