[Industrial applications]

 The present invention relates to a vehicle headlight.

[0002]

[Prior Art]

 Conventionally, in vehicle headlights, an appropriate gap is secured between the headlight and the lamp housing because it is necessary to perform aiming adjustment. That is, the aiming adjustment is to adjust the irradiation direction by holding the headlamp tiltably in the front-back and left-right directions and tilting it by the aiming mechanism at the time of assembly adjustment, inspection and replacement. In addition, the posture of the vehicle body changes depending on the load and the position on which the load is applied, which changes the irradiation direction of the headlight.Therefore, the irradiation direction can be adjusted (leveling adjustment) by a leveling mechanism provided separately from the aiming mechanism. There is also a headlight that I decided to do.

FIG. 3 is a partially broken side view showing a conventional example of a two-wheeled vehicle headlamp that enables such aiming adjustment or leveling adjustment. The lamp 1 includes a lamp body 2 whose inner surface forms a reflecting surface 2a, a front lens 3 that hermetically covers a front opening of the lamp body 2, a headlamp bulb 4 disposed in the lamp body 2, and a lamp body 2. A lamp unit 7 including a back cover 6 for covering the bulb socket 5 fitted to the rear top of the lamp unit 7, a lamp unit 7 and a lamp housing 8 for accommodating an aiming mechanism (not shown) of the lamp unit 7 are provided. There is. A seal leg 9 is integrally provided on the rear side of the outer peripheral portion of the front lens 3 over the entire circumference. The seal leg 9 is a lens mounting portion integrally provided in the front opening of the lamp body 2. It is inserted in the seal groove 11 of 10 and is fixed by an adhesive. An annular rim (metal-like decorative member) 12 that surrounds the outer periphery of the front end of the lamp unit 7, that is, the outer periphery of the lens mounting portion 10 is provided in the front opening of the lamp housing 8. The lamp unit 7 is attached to the inner surface of the support member 13 so as to be tiltable. The rim 12 is formed in an annular shape by a carbon steel thin plate or the like, and its surface is plated (chromium plated). Further, a retaining ring 14 is fitted and fixed to the outer periphery of the lens mounting portion 10. The retaining ring 14 is annularly formed of SUS material or the like and has a surface plated (chromium plated) to prevent the adhesive in the lens mounting portion 10 and the seal groove 11 from being visible from the front of the lamp. A suitable adjusting gap G for aiming is provided between this and the front end side opening edge of the rim 12.

[0004]

[Problems to be solved by the device]

 However, in the above-described conventional motorcycle headlight, since there is an aiming adjustment gap G between the rim 12 and the retaining ring 14, the interior of the lamp housing 8 is easily visible from the front, and the appearance There was a problem that the appearance was not good. Further, since the retaining ring 14 is required, the number of parts is increased accordingly, and since the retaining ring 14 is required to have corrosion resistance in particular, generally SUS material is used, and the plating treatment such as chrome plating is performed. There is also a problem that it becomes expensive because it is necessary to do. Therefore, it is conceivable to remove the retaining ring 14, but in that case, the adhesive in the lens mounting portion 10 and the seal groove 11 is visually recognized from the front of the lamp, so that the appearance is unsatisfactory and the lamp cannot be used as a lamp. I do not like it because it impairs the sense of quality.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to use a retaining ring and to impair the appearance of a lamp. An object of the present invention is to provide a vehicle headlamp which can prevent the adhesive in the lens mounting portion 10 and the seal groove 11 from being visually recognized from the front of the lamp without needing to do so, and can reduce the cost.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a lamp body having a lens mounting portion having a seal groove in a front opening, and a sealing leg integrally projecting on a peripheral edge of a rear surface, which is inserted into the sealing groove to form an adhesive. And a metal-like decorative member that is provided in a front opening of a lamp housing that houses the lamp body and that surrounds the outer peripheral portion of the front lens, and a flange portion on the outer peripheral surface of the seal leg. Is provided so as to project over the entire circumference, the flange portion is positioned to be inserted inside the opening edge portion on the front side of the metal decorative member, and a metal coating film is provided on the surface of the flange portion.

[0007]

[Action]

 In the present invention, the flange portion projecting from the outer peripheral surface of the seal leg is inserted and positioned inside the opening edge portion of the front end side of the metallic decorative member so as to overlap with the flange portion, so that the lamp unit and the lamp housing are separated from each other. Cover the adjustment gap between them to prevent the inside of the housing from being seen from the front. In addition, the metallic coating film applied to the surface of the flange portion replaces the conventional retaining ring, and the adhesive in the lens mounting portion 10 and the seal groove 11 is visible from the front of the lamp through the flange portion. To prevent.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a cutaway side view of essential parts showing an embodiment of a vehicle headlamp according to the present invention, and FIG. 2 is an enlarged view of a coating part. In the figure, the same components as those in FIG. 3 are designated by the same reference numerals and the description thereof will be omitted. In these figures, this embodiment is integrally projected on the rear surface of the outer periphery of the front lens 3 and is inserted into the seal groove 11 of the lens mounting portion 10 provided in the front opening of the lamp body 2 and bonded. A flange portion 21 is integrally provided on the intermediate portion of the outer side surface of the seal leg 9 fixed by the agent 20 over the entire circumference, and a metallic metallic coating film 24 is provided by applying silver metallic coating or the like on the surface. At the same time, the flange portion 21 is positioned to be inserted inside the front surface side opening edge portion 25 of the rim 12, in other words, the front surface side opening edge portion 25 of the rim 12 is reduced in diameter and is arranged in front of the flange portion 21. It is a non-contact overlay. In other words, the present invention is such that the metallic toning coating film 24 performs the same function as the conventional retaining ring. When coating the metallic paint film 24, the non-painted area is covered with a mask, and the metallic paint is sprayed onto the painted area by a spray gun, whereby the metallic paint film 24 can be easily painted.

At the front end of the upper surface of the lamp body 2, a rim mounting portion 27 is provided on the back surface of the lens mounting portion 10 so as to project rearward substantially horizontally, and a nut 28 is provided on the rear end surface of the rim mounting portion 27. A storage recess 29 is provided to store the rotation non-rotatably. The rear end of the engaging bracket 30 is closely attached to the upper surface of the front end of the rim mounting portion 27 and fixed by a bolt 31 that is screwed into the nut 28, and the front end is spot-welded to the inner surface of the rim 12. ing. The other structure is the same as that of the conventional device described above.

Thus, in the vehicle headlamp having such a configuration, the flange portion 21 projects from the outer peripheral surface of the seal leg 9 and the front side opening edge portion 25 of the rim 12, and the flange portion 21 serves as the lamp unit. 7 and the rim 12 are overlapped with each other so as to be located behind the adjustment gap G, the inside of the lamp housing 8 is not visually recognized from the front of the lamp through the adjustment gap G, and the appearance of the lamp is not visible. Is very good. In addition, the metal-tone coating film 24 applied to the surface of the flange portion 21 is cheaper than the conventional retaining ring, does not increase the number of parts, reduces the manufacturing cost of the lamp, and allows the flange portion 21 to pass through. The adhesive 20 in the lens mounting portion 10 and the seal groove 11 is prevented from being visually recognized from the front of the lamp.

In the above embodiment, the metal-tone coating film 24 is formed only on the surface of the flange portion 21, but the invention is not limited to this, and the shoulder portion 33 of the front lens 3 to the tip of the flange portion 21, that is, It may be formed on the surfaces of the seal leg 9 and the flange portion 21. In that case, it has an advantage that the coating can be easily performed, the coating can be closed off, and the mask can be made small. Further, although the above-described embodiment has been described with respect to the case of being applied to a motorcycle headlight, it is needless to say that the present invention is not limited to this and is also applicable to a vehicle headlight.

[0012]

[Effect of the device]
