JP2013-152896A

In the conventional vehicular lamp 101 shown in FIG. 4, water accumulates in a gap between the lamp body 101A and the bezel 103. For example, when the brake of a running vehicle is depressed, the accumulated water is shown by inertia. As indicated by an arrow in FIG. 4, there is a problem that the light leaks from the gap between the lamp body 101 </ b> A and the bezel 103 and hangs down on the design surface on the front surface of the vehicle. In particular, when the accumulated water is muddy water, there arises a problem that the design surface of the vehicle becomes dirty with muddy water.
The present invention has been made in view of the above problems, and an object thereof is to provide a vehicular lamp that can prevent dripping of water on a design surface of a vehicle.

In order to achieve the above object, the invention according to claim 1
In a vehicle lamp with a bezel covering the lower part of the lamp body,
The lamp body includes a housing provided with a light source therein, and an outer lens fixed to the housing and covering a front opening,
The bezel is formed in a plate shape covering from the lower surface front end of the outer lens to the lower surface rear end of the housing,
The front end edge of the bezel is formed with a front end wall that is bent upward in an arc shape,
A rear end wall is integrally erected along the width direction at the rear end of the bezel,
On the bottom surface of the bezel front end edge side along the inner side of the rear end wall of the bezel, a plurality of drain holes are arranged at intervals in the width direction,
The upper surface of the bezel is inclined so as to be inclined in the front-rear direction and the lower rear end side of the housing is lower than the lower front end side of the outer lens, and there is a width between the drain hole and the front end wall. A plurality of ribs extending in the direction are provided in a maze shape over at least two front and rear rows.

  According to a second aspect of the present invention, in the first aspect of the present invention, the rib has an arcuate curved surface shape that is concave toward the drain hole.

  According to the first aspect of the present invention, even if the water accumulated on the upper surface of the bezel tries to flow forward, for example, due to inertia when the brake of the vehicle is depressed, the water flow is erected on the upper surface of the bezel. It is received by the maze-shaped ribs made. The water received by the ribs flows along the slope of the upper surface of the bezel and is discharged from the drain hole. It is.

  According to the second aspect of the present invention, the rib erected on the upper surface of the bezel has an arcuate curved surface shape that is concave toward the drain hole, so that the water flow in the direction of the design surface of the vehicle is ensured by the rib. The water which is prevented and received by the ribs is efficiently guided to the drain hole along the inclination of the upper surface of the bezel and is discharged to the outside from the drain hole.

1 is a partial front view of a vehicle bumper in which a vehicle lamp according to the present invention is incorporated. It is the sectional view on the AA line of FIG. It is a top view of the bezel of the vehicular lamp concerning the present invention. It is a sectional side view of the conventional vehicle lamp.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 is a partial front view of a vehicle bumper incorporating a vehicle lamp according to the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is a plan view of a bezel of the vehicle lamp according to the present invention. It is.

The vehicular lamp 1 according to the present embodiment is incorporated in recesses 2a (only one is shown in FIG. 1) formed on the left and right sides of the front bumper 2 of the vehicle, and the lower part of the lamp body 1A is substantially horizontal. It is covered with a plate-like bezel 3 which is elongated in the lateral direction.

As shown in FIG. 2, the lamp body 1A includes an LED 7 serving as a light source and an LED substrate 8 for mounting the LED 7 in a lamp chamber 6 defined by a transparent outer lens 5 covering the housing 4 and the front opening thereof. A transparent inner lens 9 disposed in front of these (left side in FIG. 2), an extension 10 disposed in front of the inner lens 9, and the like are accommodated. Here, 6 sets of LED7 and LED board 8 which mounts this are arrange | positioned in the horizontal direction (paper surface perpendicular | vertical direction of FIG. 2), and each LED board is arrange | positioned perpendicularly .

  Thus, when current is supplied to each LED 7 to emit light, the light emitted from each LED 7 to the front of the vehicle passes through the inner lens 9 and then the light distribution is controlled, and then passes through the outer lens 5. And then exits to the front of the vehicle.

  By the way, the bezel 3 arranged at the lower part of the lamp body 1A is integrally formed in a plate shape elongated in the width direction as shown in FIG. 3 with a light-impermeable resin, and as shown in FIG. The upper surface constitutes an inclined surface that is slightly inclined so as to descend toward the rear of the vehicle (rightward in FIG. 2). Here, as shown in FIG. 2, a front end wall 3a bent upward in an arc shape is formed at the front end edge of the bezel 3, and the width direction (the left-right direction in FIG. 3) is formed at the rear end portion. ) Along the rear end wall 3b. As shown in FIG. 3, cylindrical mounting bosses 2c are integrally formed at two places in the width direction of the rear end wall 3b of the bezel 3, and the upper surface of the bezel 3 is connected to the front of the vehicle from each boss 3c. Reinforcing ribs 3d extending linearly (in the lower part of FIG. 3) are erected integrally.

  Further, as shown in FIG. 3, a plurality of ribs 3e and 3f extending in the width direction are provided on the upper surface of the bezel 3 in a maze shape across two rows in the front-rear direction. Is a portion along the inner side of the rear end wall 3b), and three drain holes 11 having a long hole shape in the lateral direction are formed at predetermined intervals in the width direction. Here, the front four ribs 3e (3e1, 3e2, 3e3, 3e4) are arranged at a predetermined interval in the width direction, and the three ribs 3e2, 3e3, 3e4 are formed in the drain holes. 11 is formed in an arcuate curved surface that is concave (toward the rear).

  The three rear ribs 3f (3f1, 3f2, 3f3) are staggered with respect to the four front ribs 3e (3e1 to 3e4) (that is, the three rear ribs 3f (3f1 to 3f3). ) Are arranged in a staggered manner so as not to overlap with the gap between the four front ribs 3e (3e1 to 3e4) in the front-rear direction. ) And the three rear ribs 3f (3f1 to 3f3) are arranged in a maze shape. The rear three ribs 3f (3f1 to 3f3) are also formed in an arcuate curved surface that is concave toward the drain hole 11 (rearward).

  In the vehicular lamp 1 configured as described above, rain water, washing water, muddy water splashed by wheels, and the like (hereinafter simply referred to as “water”) accumulate on the upper surface of the bezel 3. For example, even if an attempt is made to flow toward the front of the vehicle as indicated by a broken line arrow in FIG. 3 due to inertia when the brake of the vehicle is depressed, this water flow is a maze-like front and rear standing on the upper surface of the bezel 3 Are received by the plurality of ribs 3e, 3f. The water received by the ribs 3e and 3f flows to the rear of the vehicle along the inclination of the upper surface of the bezel 3 as shown by solid arrows in FIG. Occurrence of a problem that the design surface of the vehicle hangs down on the design surface of the vehicle and stains the design surface is prevented.

  In this embodiment, the front ribs 3e (3e2 to 3e4) and the rear ribs 3f (3f1 to 3f3) standing on the upper surface of the bezel 3 are recessed toward the drain hole 11 (rear of the vehicle). Therefore, the flow of water in the direction of the vehicle design surface (front of the vehicle) is reliably prevented by the ribs 3e and 3f, and the water received by the ribs 3e and 3f is inclined on the upper surface of the bezel 3. Are efficiently led to a plurality of drain holes 11 and discharged from each drain hole 11 to the outside.

  In the present embodiment, since the three drain holes 11 are formed in the bezel 3 along the width direction, the water accumulated on the upper surface of the bezel 3 can be efficiently discharged from the three drain holes 11. The drain hole 11 is not limited to three, and two or four or more drain holes may be formed.
