DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing water dripping when an opening or opening and closing of a trunk lid in a vehicular device such as a lamp or a decorative device attached to the trunk lid. Here, the lamp means a rear combination lamp or the like. In addition, the decoration device refers to a rear finisher or the like. That is, the vehicle device refers to a device in which a light room or a room is defined by a housing, a lens, and the like.

[0002]

2. Description of the Related Art A vehicle apparatus of this type will be described with reference to FIGS. In this example, an example in which the vehicle device is a rear combination lamp will be described. In the figure, A is a rear combination lamp as a device for a vehicle, and this rear combination lamp A has a turn signal lamp B, a tail stop lamp C,
It comprises a combination of a back lamp D and a tail lamp E. This rear combination lamp A
Includes a lamp housing 1, an outer lens 2, an inner lens 3, a colored cap 4, a reflector 5, and the like.

An opening is provided on the front surface of the lamp housing 1, and a seal recess 10 is provided on the entire periphery of the front opening. The seal leg 10 of the outer lens 2 is provided in the seal recess 10 of the lamp housing 1.
Are sealed by a sealing material, for example, a hot melt 21. A plurality of lamp chambers 22 are defined by the lamp housing 1 and the outer lens 2. In the plurality of lamp chambers 22, an inner lens 3, a colored cap 4, a reflector 5, and the like are provided. The light source bulbs 6 of the lamps (the turn signal lamp B, the tail stop lamp C, the back lamp D, and the tail lamp E) having the respective functions described above are disposed in the plurality of lamp chambers 22, respectively. The rear combination lamps A are mounted on the left and right sides of the rear trunk lid 70 of the vehicle 7 respectively. In the drawing, reference numeral 71 denotes a bumper.

[0004]

However, in the rear combination lamp A as the above-described vehicle device, the seal concave portion 10 of the outdoor lamp housing 1, the seal leg portion 20 of the outer lens 2, and the hot melt 2
A seal space 23 is formed in a substantially rectangular shape along the rectangular outer shape of the rear combination lamp A in a portion surrounded by 1. For this reason, as shown by the arrow in FIG. 10, water W may enter the seal space 23 on the upper side of the rear combination lamp A or on both left and right sides. When water W enters the seal space 23, the water W travels through the seal space 23 by its own weight, and the seal space 2 on the lower side of the rear combination lamp A
Collect in 3. Then, as shown in FIG. 8, the water W is supplied to the seal space 23 on the lower side of the rear combination lamp A.
When the trunk lid 70 is opened and closed, particularly when the trunk lid 70 is opened, particularly when the trunk lid 70 is opened, the water W accumulated in the above-described seal space 23 may drop as water droplets.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure for a vehicle apparatus, which prevents opening and closing of a trunk lid, in particular, dripping when the trunk lid is opened.

[0006]

According to the present invention, in order to achieve the above object, a chamber is defined by sealing a sealing recess of a housing and a sealing leg of a lens with a sealing material such as hot melt. In a vehicle device, a rib is provided to prevent water that has penetrated into a seal space surrounded by a seal concave portion, a seal leg, and a seal material on the outdoor side from traveling through the seal space and accumulating at a certain position in the seal space. A notch is provided in the seal space, and a notch for discharging water that has penetrated into the seal space and transmitted through the seal space to the outside of the seal space transmits water more than ribs in the seal concave portion on the outdoor side. It is characterized by being provided on the upstream side.

[0007]

Further, the present invention is characterized in that a rib is provided in the seal space to prevent water that has entered the seal space from propagating through the seal space and accumulating at a certain position in the seal space.

According to the present invention, water does not accumulate at a certain location in the seal space due to the notch function of discharging water that has penetrated into the seal space and transmitted through the seal space to the outside. Further, according to the present invention, water does not accumulate at a certain position in the seal space due to the action of the rib for blocking water that has entered the seal space and transmitted through the seal space.

As a result, according to the present invention, water can be prevented from accumulating at a certain point in the seal space by the independent action or the combined action of the notch and the rib, so that the trunk lid is opened and closed, and particularly the trunk lid is opened. Water dripping at the time can be prevented.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, three examples of embodiments of a dripping prevention structure in a vehicle device according to the present invention will be described with reference to FIGS. 1 to 3 show a first embodiment of a structure for preventing dripping in a vehicle device according to the present invention. In this example, an example in which the vehicle device is a rear combination lamp will be described. In the figures, FIGS.
The same reference numerals denote the same components.

In FIG. 1, reference numeral 8 denotes a rib provided integrally with the seal leg 20 on the outer lens 2 outside the lamp chamber 22. The rib 8 is for preventing water W that has entered the seal space 23 from traveling along the seal space 23 and accumulating in the seal space 23 on the lower side of the rear combination lamp A. Of these, the rear combination lamp A is provided at the lower side near the left and right ends.

In FIG. 1, reference numeral 9 denotes a cutout provided in the seal recess 10 outside the lamp chamber 22 of the lamp housing 1.
The notch 9 is for discharging the water W that has entered the seal space 23 and transmitted through the seal space 23 to the outside of the seal space 23. It is provided on the upstream side of the rib 8 where the water W is transmitted, that is, on the lower side of the rear combination lamp A near the left and right ends.

Since the mounting structure of the vehicle device according to the present invention in this embodiment has the above-described configuration, the water W that has entered the seal space 23 and transmitted through the seal space 23 is By the action, the lower left and right sides of the rear combination lamp A in the seal space 23 are blocked. Further, the blocked water W is discharged out of the seal space 23 by the action of the notch 9. As described above, the water W blocking action of the rib 8 and the water 2W discharging action of the notch 9 prevent water W from accumulating in the seal space 23 of the lower piece of the rear combination lamp A. As a result, it is possible to prevent the trunk lid 70 from being opened and closed, and in particular, from hanging down when the trunk lid 70 is opened.

FIGS. 4 and 5 show a second embodiment of the structure for preventing dripping in a vehicle device according to the present invention. In the drawings, the same reference numerals as those in FIGS. 1 to 3 and 8 to 13 denote the same components. In the mounting structure of the vehicle device according to the present invention in this embodiment, notches 9 are provided at the left and right ends of the lower side of the rear combination lamp A in the seal recess 10 outside the light room 22.
