Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dummy lamp for automobiles.

[Conventional technology]

This type of artificial lighting for automobiles generally consists of a lens made of synthetic resin and a housing made of synthetic resin, which are welded around the entire circumference by ultrasonic welding or the like to seal the space partitioned by the lens and housing. The screw is inserted into the boss part provided on the lens and housing to attach it to the vehicle body.
This artificial lamp for automobiles does not itself have a light emitting function, and is installed as a dummy product for the design of the automobile.

Such a pseudo-light for automobiles has a lens and a housing that are welded around the entire circumference to seal the space defined by the lens and housing.
Because the air in the above-mentioned closed space expands and contracts due to the temperature difference between daytime and nighttime, it is necessary to provide a means for breathing between the inside and outside of the lamp. The parts were attached to the housing.

[The problem that the idea aims to solve]

As mentioned above, the conventional artificial lamps for automobiles have a separate component that has a breathing function attached thereto, which increases the cost accordingly.

The present invention aims to improve these points and provide a pseudo lamp for an automobile that has a breathing function, even though it does not use any separate parts that have a breathing function.

[Means to solve the problem]

In the present invention, the lens and the housing are welded around the entire circumference to seal the space partitioned by the lens and the housing, and the lens and the housing are formed with boss portions that abut each other. A pseudo lamp for an automobile that is attached to a vehicle body by inserting a screw into the lamp, characterized in that a breathing groove is provided on the contact surface of at least one of the lens boss portion and the housing boss portion to communicate the internal space and the screw insertion hole. shall be.

[Effect]

A pseudo light for an automobile is attached to the car body by forming a boss part on the lens and the housing that abuts each other, and inserting a screw into the boss part.The entire circumference of the lamp is welded to seal the space divided by the lens and housing. Even so, there is a slight gap between the screw insertion hole of the boss section and the screw, and between the abutting surfaces of the lens boss section and the housing boss section, and some breathing action is expected to take place from there.

The present invention focuses on this point and forms a breathing groove on the contact surface of at least one of the lens boss part and the housing boss part to communicate the internal space with the screw insertion hole. Breathing action can be performed by communicating the space and the screw insertion hole.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a dummy lamp for an automobile according to the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a lens made of synthetic resin, for example, acrylic resin, and this lens 1 has an inner surface 1
0 has a planar rectangular shape processed into a prism, and a welding leg 11 is provided on the lower surface thereof protruding over the entire circumference, and a cylindrical boss portion 1 is provided on the lower surface approximately at the center of the two short sides.
2 are integrally protruded. Reference numeral 2 denotes a housing made of a synthetic resin, for example, ABS resin, and the housing 2 has a planar rectangular shape that is one size larger than the lens 1, and has a welded portion 21 protruding from its upper surface over the entire circumference. A cylindrical boss portion 22 is provided above and below the center of the short side of the boss portion 1 of the lens 1.
It is provided in correspondence with 2. In addition, this lens 1
boss portion 12 of the housing 2 and the upper boss portion 2 of the housing 2
2 and the height of the welding leg 11 of the lens 1 is that when the welding leg 11 of the lens 1 is placed on the welding part 21 of the housing 2, the boss part 12 of the lens 1 and the boss part 22 of the housing 2 There is a height relationship where they touch.

In the present invention, the upper surface of the boss portion 22 of the housing 2,
That is, a V-shaped breathing groove 7 is provided in the portion of the lens 1 that contacts the boss portion 12, which allows communication between the screw insertion hole 8 and the portion that becomes the space inside the lamp.
The welding leg 11 of the lens 1 is placed on the welding part 21 of the housing 2, and the boss part 12 of the lens 1 is brought into contact with the boss part 22 of the housing 2. In this state, the welding leg 11 of the lens 1 is and the welded portion 21 of the housing 2 are welded by ultrasonic welding or the like to seal the space 3 partitioned by the lens 1 and the housing 2. Then, the screw 4 is inserted into the screw insertion hole 8 of the boss portion 12 of the lens 1 and the boss portion 22 of the housing 2, and the screw 4 is screwed into the spring nut 6 attached to the vehicle body 5, so that the lens 1 and the housing 2 are attached to the vehicle body.
Attach to. Note that 40 is a sheet with the head of the screw 4 interposed between it and the lens 1.

Since the artificial lamp for automobiles of the present invention has the above-described configuration, when the air in the space 3 inside the lamp tries to expand or contract due to the temperature difference between daytime and nighttime, the space 3 expands and contracts through the breathing groove 7. Since it communicates with the insertion hole 8 of the screw 4, the space 3 inside the lamp and the outside of the lamp can effectively breathe through the breathing groove 7 and the insertion hole 8 of the screw 4.

In the above-described embodiment, the breathing groove 7 was provided in the boss portion 22 on the housing 2 side.
It may be provided on the side boss portion 12 or may be provided on the boss portions 12 and 22 of both the lens 1 and the housing 2.

[Effect of idea]

As described above, according to the present invention, the space inside the pseudo lamp can be communicated with the outside of the lamp to allow effective breathing, without using any separate parts with a breathing function such as grommets. Therefore, costs can be reduced accordingly.
