Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fog lamp, also referred to as an auxiliary headlight, and more particularly to a fog lamp of a type which is supplied to the market as a commercial part and can be mounted by a user.

[0002]

2. Description of the Related Art FIG. 3 shows an example of the configuration of a conventional fog lamp 90 of this type in a main part. In the fog lamp 90, a lens 91a and a reflecting mirror 91b constitute a closed body 91. It is assumed that the light bulb 92 is attached to the sealing body 91, the sealing body 91 is fitted into the housing 93, and is attached by screwing on a side surface. When replacing the light bulb 92, the sealing body 91 is removed from the housing 93. It is assumed that replacement is performed in this state.

[0003]

However, in the above-mentioned conventional configuration, the lens 91a and the reflecting mirror 9 are certainly used.
1b has a sufficient waterproofing performance, but is insufficient between the sealing body 91 and the housing 93. As a result, the moisture that has entered the housing 93 can be removed from the socket of the light bulb 92 or the like. In this case, a problem arises in that the intrusion into the sealing body 91 through the above-mentioned structure causes dew condensation or the like, thereby deteriorating the user's sense of reliability, and the solution of this problem has been an issue.

[0004]

According to the present invention, as a specific means for solving the above-mentioned conventional problems, a lens formed as a closed body and a reflecting mirror are detachably mounted on an irradiation direction side. In a fog lamp attached to a housing, a rib having an H-shaped cross section is provided on one inner side of the housing by providing a rib protruding forward in parallel with an outer shell at an appropriate distance on an inner diameter side of the housing. The fog lamp is provided so that the other U-shaped part of the packing comes into contact with the rear surface of the reflecting mirror when the sealing body is attached. ,
This is to solve the above-mentioned conventional problem.

[0005]

Next, the present invention will be described in detail with reference to an embodiment shown in the drawings. 1 and 2 is a fog lamp according to the present invention.
Is supplied to the market as a commercial part and therefore the lens 2a
And the reflecting mirror 2b form a closed body 2, and the closed body 2 is detachably attached to the housing 3 so that the bulb 5 can be replaced. It is.

However, according to the present invention, the housing 3 has a rib 3b which is parallel to the outer shell 3a at an appropriate distance from the outer shell 3a so that the projecting direction is directed toward the irradiation direction, that is, forward. In addition, the rib 3b is provided with a packing 4 having a substantially H-shaped cross section and formed of an elastic member such as rubber, and one of the above-mentioned H-shaped U-shaped portions 4a. To be mounted so as to straddle the rib 3b.

At this time, the packing 4 is attached to the rib 3
b, it may be formed as a ring so as to have the same shape as that of the rib 3b, or it may be formed as a linear elongated member, cut into a predetermined length, and attached to the rib 3b. The end surfaces may be abutted with each other to cover the entire circumference of the rib 3b.

The housing 3 to which the packing 4 has been attached as described above has the sealing body 2 attached thereto in the same manner as in the conventional example. At this time, in the housing 3 at the design stage, the packing 3 is provided. The position of the rib 3b is set so that the other one of the U-shaped portions 4b 4 is pressed against the back surface of the reflecting mirror 2b with appropriate strength.

Next, the operation and effect of the fog lamp 1 of the present invention having the above-described structure will be described. The housing 3 is provided with a rib 3b, and the rib 3b is connected to the other end of the reflecting mirror 2b at the other end. By mounting the packing 4, which is in close contact with the back surface, that is, the back surface of the sealing body 2, the fog lamp 1 has a waterproofing property even between the sealing body 2 and the housing 3, thereby preventing water from entering the housing 3. Therefore, water or humidity does not enter the sealed body 2 through the socket of the light bulb 5 or the like.

In actual practice, the waterproof performance can be further enhanced by, for example, flattening the portion of the back surface of the sealing body 2 with which the packing 4 comes into contact. is there.

[0011]

As described above, according to the present invention, a rib having an H-shaped cross section is provided on the inner diameter side of the housing in parallel with the outer shell at an appropriate distance and protruding forward. A conventional fog lamp in which the other U-shaped part of the packing comes into contact with the back surface of the reflecting mirror when the sealed body composed of the lens and the reflecting mirror is attached. In addition to waterproofing between the lens and the reflecting mirror, waterproofing between the hermetically sealed body and the housing shall be performed to prevent infiltration into the housing. To prevent the occurrence of dew condensation on the lens surface, thereby preventing the user from feeling distrusted, and has an extremely excellent effect on performance improvement and commercialization. Things.
