JPS6011526Y2 - Vehicle lamp drain hole - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a drain hole for lamps used in vehicles such as automobiles.

In conventional vehicle lamps that are bulb replaceable, it is difficult to completely seal the bulb mounting portion.

Since it is difficult to drain water once it has entered the lamp chamber to the outside, a drain hole is usually provided at the rear or bottom of the lamp chamber to drain the water inside the lamp chamber.

However, this drain hole allows water to enter the lamp chamber if it is directly hit by water.

Therefore, in the past, a partition plate was installed below the lamp chamber to prevent water from directly hitting the car body, and this prevents the drain hole from being hit directly by water when the car is driving on roads with puddles or when washing the car. .

However, even if a partition plate is provided, it is difficult to completely prevent direct impact from water, and there is a drawback that the number of parts increases.

The purpose of this invention is to provide a drainage hole for a lamp that can sufficiently prevent water from entering the lamp chamber even if it is directly hit by water without using a partition plate.

This invention will be explained below with reference to drawings showing embodiments.

The figure shows a side view of the front end of the vehicle, with arrow A indicating the direction of travel of the vehicle.

1 is an outer panel of the vehicle body, and 2 is a clearance lamp.

The clearance lamp 2 includes a lamp lens 3, a lamp body 4, and a bulb 5 attached to the surrounding wall 4a of the lamp body 4.
It consists of

4b is a partition wall inside the lamp body 4.

A lamp chamber 4c is formed within the lamp body 4 by the lamp lens 3, surrounding wall 4a, and partition wall 4b, and the bulb 5 is disposed within the lamp chamber 4c.

A drainage boat 6. is attached to the surrounding wall 4a forming the lamp chamber 4c.
6, into which one open end 7a of a U-shaped pipe 7 with both ends open is inserted, and the other open end 7b is connected to the surrounding wall 4.
It is close to and facing a.

A drain 68 is formed by the port 6 and the pipe 7.

The drain 68 is curved in a U-shape as described above, and one opening end thereof communicates with the lamp chamber 4c, and the other opening end is close to and facing the surrounding wall 4a of the lamp body 4, so that the lamp chamber 4c is curved. Water accumulated in 4c is easily drained from the other open end 7b.

On the other hand, since the other open end 7b is closely opposed to the surrounding wall 4a, it is impossible for water to enter the open end 7b from a direction perpendicular to the end surface of the open end 7b.

Furthermore, even if water rushes toward the end face of the open end 7b from an oblique direction, the angle of inclination of the water flow with respect to the end face of the open end 7b is small because the open end 7b is close to and opposed to the surrounding wall 4a as described above. Water intrusion is extremely difficult.

In other words, water does not enter the lamp chamber 4c from the other open end 7b when washing the car or driving on a road with puddles.
It is impossible even if b is directly hit by water.

In this invention, there is no need to provide a partition plate near the other open end of the drain 68, so it has an excellent effect on vehicles where it is impossible to install a partition plate below the lamp chamber.

Furthermore, since the number of parts is reduced by the amount of the draining plate, it is also effective in reducing the cost of the vehicle.
