Abstract

(57) [Abstract] [Purpose] In conventional vehicle headlamps, a breathing hole for the purpose of preventing fogging was provided on the housing side. The breathing hole penetrates through the lens and is viewed, which causes a problem that the viewer feels uncomfortable. [Structure] The breathing hole 4 is on the side of the lens 2 and is a vehicle headlamp 1 provided at a position of a leg portion 2a of the lens 2 which is covered by a vehicle body 10, so that the breathing hole 4 can be moved from the housing 3. As a result, it is difficult to see, and the problem is solved by preventing an uncomfortable feeling.

[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle headlamp, and more particularly to a structure of a breathing hole provided in the vehicle headlamp for the purpose of preventing fogging.

[0002]

[Prior Art]

 FIG. 3 shows an example of the configuration of a conventional vehicle headlamp 90 of this type, and the chamber formed by the lens 91 and the housing 92 that also serves as a reflecting mirror is in a sealed state. It may absorb moisture due to pressure change due to repeated lighting and extinction over a long period of time, resulting in fog inside. Therefore, a breathing hole 93 should be formed in advance on the back surface of the housing 92 to create a pressure difference between the inside and outside of the chamber. I try not to occur.

[0003]

[Problems to be solved by the device]

 However, in the recent vehicle headlamp 90, there is a tendency that the lens 91 is required to have a strong sense of transparency due to the requirements of automobile design, and the lens cut to be performed on the lens 91 becomes shallow. In this case, the breathing hole 93 passes through the lens 91 and is directly viewed to give an uncomfortable feeling, which causes a problem that the aesthetics of the vehicle headlamp 90 is greatly impaired. Had become an issue.

[0004]

[Means for Solving the Problems]

 As a concrete means for solving the above-mentioned conventional problems, the present invention provides a vehicle headlamp having a breathing hole for preventing fogging in a chamber formed by a lens and a housing. By providing a vehicle headlamp characterized in that the hole is provided on the side of the lens and at the position of the leg covered by the vehicle body of this lens, the breathing hole is made difficult to be seen. This is to solve the conventional problems.

[0005]

Embodiment Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 denotes a vehicle headlamp according to the present invention. The vehicle headlamp 1 has a lens 2 and a housing 3 which form a sealed chamber, and the chamber is formed in the chamber. As in the conventional example, a breathing hole 4 for preventing fogging is provided.

However, according to the present invention, the breathing hole 4 is provided on the lens 2 side, and the position where the breathing hole 4 is provided is because the lens 2 and the housing 3 are joined to each other. The frame 2 is provided on the leg portion 2a, and the leg portion 2a is also covered with the vehicle body 10 so that the lens 2 is difficult to see when viewed from the front of the vehicle.

At this time, when the breathing hole 4 is provided, in consideration of the pulling direction from the mold when molding the lens 2, etc., for example, a split mold or a slide mold is used as a mold for molding the breathing hole 4. It is preferable that both the breathing hole 4 and the leg portion 2a have appropriate shapes so as not to cause a complicated configuration.

Next, the operation and effect of the vehicle headlamp 1 of the present invention having the above-described structure will be described. The side of the housing 3 which is likely to be seen through the lens 2 through the breathing hole 4 To the lens 2 side and the position thereof is set to the leg portion 2a covered by the vehicle body 10, so that the breathing hole 4 is not viewed in a normal viewing state, and a feeling of strangeness is generated. To prevent.

As shown in FIG. 1, a rubber tube 5 is normally connected to the breathing hole 4 to prevent water from entering from the outside, but as shown in FIG. It is also possible to freely select a means such as forming the labyrinth 4a and omitting the rubber tube 5 when providing 4, and in this case as well, it is said that the above-described actions and effects can be similarly obtained. There is no end.

[0010]

As described above, according to the present invention, the breathing hole is on the lens side, and the vehicular headlamp is provided at the position of the leg portion covered by the vehicle body of the lens. Even in the recent vehicle headlights where the inside of the headlight is easily seen through due to the transparent lens etc., it is possible to avoid viewing the breathing hole, so that the viewer does not feel discomfort. As a result, it has an extremely excellent effect on improving the aesthetics.
