DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a lamp attached to a luggage door for a vehicle such as a passenger car, and more particularly, to water for preventing rainwater, washing water, etc. from entering the gap of the lamp from dropping into a trunk room. It relates to a droop prevention structure.

[0002]

2. Description of the Related Art In recent years, the rear body of a passenger car has been increasingly integrated with a luggage door and various lamps. FIGS. 4 and 5 show a lamp attached to a luggage door of a conventional vehicle of this type. 4 is a rear perspective view of the passenger car with the luggage door opened, and FIG.
FIG. 4 is a cross-sectional view taken along line AA of the brake lamp 19 shown in FIG. FIG.
As exemplified in FIG. 1, the rear body 10 of the passenger car is provided with a turn signal lamp 17 and a tail lamp 18 integrated with a rear fender 21, and a brake lamp 19 is provided on a side end surface of the luggage door 1. ,
Various lamps such as a backup lamp 20 are provided. When the luggage door 1 is opened and closed, these lamps 1
The reference numerals 9 and 20 move up and down accompanying the luggage door 1.

As shown in FIG. 5, these lamps have a bulb 9 housed inside a housing 5 and a gasket 6 arranged annularly along the bottom of the housing 5 to form a lamp. When the lens 4 is fitted to the side, the opening 2 of the housing 5 is closed. In this case, the gaps a and b formed between the lens 4 and the housing 5 are designed to be as narrow as possible to improve the appearance.

In the conventional lamp with a luggage door having such a structure, when water is applied to the lamp of the luggage door 1 during rainfall or car washing, water penetrates into the gaps a and b due to a capillary phenomenon, so that the gap is removed. Rain water and the like may accumulate in a and b. Then, when the luggage door 1 is opened and closed, the accumulated water drops into the trunk room 3,
The dust may fall into the luggage in the luggage compartment, or the dust entering the gaps a and b of the lamp may be mixed with water and solidified.

Therefore, as a countermeasure for preventing water dripping, as shown in Japanese Utility Model Publication No. 4-55362, a cup is provided at the lower part of the housing, and the water accumulated in the gap when the luggage door is opened is temporarily transferred to the cup. There is disclosed a structure of a lamp with a luggage door in which water in a cup is discharged to the outside from a drain hole at the bottom of the housing when the luggage door is closed.

[0006]

However, in the above structure, when the luggage door is closed, water is accumulated in the gap between the lens and the housing.
It is inevitable that dust and the like mix with water and solidify in the gaps. In addition, while opening the luggage door,
It is impossible to drop all the water staying in the gap by the surface tension into the cup. Also, the water staying in the gap may be scattered outside in the opposite direction and fall into the trunk room due to the impact of the vertical movement when the luggage door is opened.

SUMMARY OF THE INVENTION In view of the above, the present invention provides a luggage door provided to prevent rainwater and washing water from collecting in a gap between a lens of a lamp and a housing attached to the luggage door and to prevent water from entering a trunk room. It is an object of the present invention to provide a dripping prevention structure in a type lamp.

[0008]

In order to achieve the above object, a drip prevention structure according to the present invention is provided for a lamp to be attached to a luggage door of a vehicle. A valve,
A lens that is coupled to the housing and accommodates the valve inside the housing, and has a packing for coupling the lens and the housing in a watertight manner, and water that has entered the gap between the housing and the lens, It is configured to discharge through a pipe-shaped drain hole.

With such a configuration, when water is applied to the lamp of the luggage door during rainfall or car washing, water accumulated in the gap between the lamp housing and the lens due to the capillary phenomenon is moved downward from above by gravity. The water flows together, passes through the gap at the side, reaches the gap at the bottom, and is discharged to the outside of the passenger car through a pipe-shaped drain hole provided at the bottom of the housing. Therefore, water is less likely to collect in the gap between the lens and the housing of the lamp attached to the luggage door, and it is possible to prevent water from dripping into the trunk room.

The housing 11 includes a convex lens 8 that covers the opening surface of the housing 11 and is attached to the front surface side, and an annular packing 13 for connecting the convex lens 8 and the housing 11 in a watertight manner. The housing 11 covers the side of the convex lens 8 with a fixed small gap in order to improve the appearance of the lamp 7, and the cylindrical leg 26 of the convex lens 8 is combined with the packing 13 to form a watertight structure. Has formed.

The convex lens 8 is formed in a U-shaped cross section as shown in FIG. 1, and a protruding portion 12 is provided on the periphery of the convex lens 8. The peripheral end 25 of the housing 11 is formed to be divergent, corresponding to the shape of the convex lens 8 having such a protruding portion 12.

Further, the bottom portion 14 of the housing 11 is formed thick because it is joined to a lower end portion (not shown) of a luggage panel of a luggage door. The above-mentioned pipe-shaped drain hole 15 is opened in the housing bottom part 14 located rearward from the projection part 12 located at the bottom.

The shape of the convex lens 8 having a U-shaped cross section is as follows.
The front can be changed to a square or a circle, and the shape of the opening 23 of the housing 11 can be changed according to the shape of the convex lens 8. If the leg 26 of the convex lens 8 is not cylindrical but presents, for example, a rectangular shape, the upper surface of the leg is located at the center as viewed from the front of the rear part of the vehicle so that water easily falls down. Is preferably the highest and the left and right ends are inclined to be the lowest. Further, for the same reason, it is preferable that the housing bottom portion 14 is provided with a funnel-shaped slope so that the inlet portion of the pipe-shaped drain hole 15 is the lowest.

Next, the operation of the present embodiment will be described.
FIG. 2 is a diagram showing a state in which water flows down a pipe-shaped hole in the water dripping prevention structure of the present invention. FIG.
When the water 16 flows along the pipe-shaped drain hole 15, the viscosity of the water causes the water 16 to flow as a fluid instead of flowing individually as water droplets.

FIG. 3 shows a structure for preventing dripping according to the present invention.
It is the figure which showed the path | route until water flows down the pipe-shaped drainage hole 15 and flows down. Referring to FIG. 3, water 16 accumulated in a gap between housing 11 and convex lens 8 due to capillary action flows downward from above by gravity, as indicated by an arrow, and integrally forms housing 11 and convex lens 8. 8 to the gap at the housing bottom 14 and is discharged to the outside of the passenger car through the pipe-shaped drain hole 15. In addition, water that accumulates in the portion D shown in FIG. 1 is discharged to the outside through a gap entrance between the leg portion 26 of the convex lens 8 and the bottom portion 14 of the housing 11, or is discharged to the outside through a pipe-shaped drain hole 15. Some are.

The water droplets usually fall from the upper part of the housing as a continuous and integrated fluid, and the diameter of the water is often about 4 mm to 5 mm. Therefore, when the diameter of the pipe-shaped drain hole 15 is smaller than the diameter of water, water cannot be discharged to the outside through the pipe-shaped hole 15. For this reason, it is preferable that the diameter of the pipe-shaped drain hole 15 be 7 mm or more. The housing and the convex lens are preferably made of a material having good drainage.
