Description

この発明は、自動車のヘッドランプ、リアランプ、フォグランプ等の外装ランプのフランジ部の構造に関する。   The present invention relates to a structure of a flange portion of an exterior lamp such as a headlamp, a rear lamp, and a fog lamp of an automobile.

自動車のヘッドランプ、リアランプ、フォグランプ等の外装ランプは、外装側のランプレンズと車体側に設けられているランプハウジングとを係合させており、外装ランプのフランジ部の構造は、図10に示すように、透明なランプレンズ100の一部であるフランジ部101と、ランプハウジング102との間に形成される溝部103が形成される。   Exterior lamps such as automobile headlamps, rear lamps, and fog lamps engage a lamp lens on the exterior side with a lamp housing provided on the vehicle body side, and the structure of the flange portion of the exterior lamp is shown in FIG. Thus, a groove 103 formed between the flange 101 that is a part of the transparent lamp lens 100 and the lamp housing 102 is formed.

そしてランプレンズ100側の一部であるフランジ部101の溝部103を形成する面(フランジ部裏面)にローレット104を設けていた。ローレット104は、図8に示すようにカマボコ型の複数のローレット凸部104aを隣接して並列させた形状であり、ローレット凸部104aの方向は、溝部103の奥行き方向に向いて形成されていた。   The knurling 104 is provided on the surface (the flange portion back surface) on which the groove portion 103 of the flange portion 101 which is a part of the lamp lens 100 side is formed. As illustrated in FIG. 8, the knurling 104 has a shape in which a plurality of knurled convex portions 104 a are adjacently arranged in parallel, and the direction of the knurling convex portion 104 a is formed so as to face the depth direction of the groove portion 103. .

また、フランジ部101を含むランプレンズ100は透明素材から形成されており、外部から溝部103の中は見ることができた。   In addition, the lamp lens 100 including the flange portion 101 is made of a transparent material, and the inside of the groove portion 103 can be seen from the outside.

しかしながら、従来の外装ランプのフランジ部構造であると、雨天や洗車等によって外装ランプが水を被った場合、水の表面張力によってフランジ部101の溝部103の中に水滴Wや泥が残りやすい問題があり、その残った水Wや泥、埃が透明なフランジ部101を通して外部から見えてしまい、非常に見栄えが悪い問題点があった。   However, in the case of the flange portion structure of the conventional exterior lamp, when the exterior lamp is covered with water due to rain or a car wash, water droplets W and mud are likely to remain in the groove portion 103 of the flange portion 101 due to the surface tension of the water. The remaining water W, mud, and dust are visible from the outside through the transparent flange portion 101, and there is a problem that the appearance is very bad.

そのため、溝部の内部を見えなくするためにローレット104(ローレット凸部104a)の表面に不透明塗料を塗装する方法が行なわれていた。しかしローレット104の表面を塗装する作業は、時間及び費用が掛り、塗装費用が1台1000円程度掛る課題があった。   Therefore, in order to make the inside of the groove invisible, a method of applying an opaque paint on the surface of the knurled 104 (knurled convex portion 104a) has been performed. However, the operation of painting the surface of the knurl 104 takes time and expense, and there is a problem that the painting cost is about 1000 yen.

上記課題を解決するために、外装ランプにおいて、ランプレンズのフランジ部とランプハウジングの間に形成される溝部のフランジ部溝面側にローレットを設けるとともに、ローレット凸部の長手方向に複数の凹部を設けたことを特徴とする外装ランプのフランジ部の構造を提案する。   In order to solve the above-described problem, in an exterior lamp, a knurling is provided on the groove surface side of the groove formed between the lamp lens flange and the lamp housing, and a plurality of recesses are provided in the longitudinal direction of the knurling projection. The structure of the flange part of the exterior lamp characterized by having provided is proposed.

また、ローレット凸部に設けられ凹部が、隣接するローレット凸部の凹部と、ローレット凸部の長手方向の位置で同じ位置とならない凹部である0007欄に記載の外装ランプのフランジ部の構造を提案する。   In addition, the structure of the flange portion of the exterior lamp described in the column 0007, in which the concave portion provided in the knurled convex portion is not the same position as the concave portion of the adjacent knurled convex portion and the longitudinal position of the knurled convex portion, is proposed. To do.

更に、ローレット凸部に設けられ複数の凹部のそれぞれが、ローレット凸部の長手方向において等間隔に設けるとともに、隣接する相互のローレット凸部の複数の凹部が、互いに隣接するローレット凸部の2つの凹部間のほぼ中央に位置する0007欄又は0008欄に記載の外装ランプのフランジ部の構造を提案する。   Further, each of the plurality of concave portions provided on the knurled convex portion is provided at equal intervals in the longitudinal direction of the knurled convex portion, and the plurality of concave portions of the adjacent knurled convex portions are two adjacent knurled convex portions. The structure of the flange part of the exterior lamp described in the 0007 column or the 0008 column located approximately in the center between the recesses is proposed.

この発明によれば、自動車等に設ける外装ランプのランプレンズのフランジ部とランプハウジングの間に形成される溝部の中に、洗車や雨によって水分が入った場合でも、ローレット凸部に設けられた複数の凹部によって表面張力が失われるため重力等によって、溝部から容易に水分は落下や蒸発によって排出され、溝部内に泥や埃が固着して残ることがなくなった。   According to the present invention, the groove formed between the flange portion of the lamp lens of the exterior lamp provided in the automobile or the like and the lamp housing is provided on the knurled convex portion even when water enters due to car washing or rain. Since the surface tension is lost by the plurality of concave portions, moisture is easily discharged from the groove portion due to gravity or the like by dropping or evaporation, and mud and dust do not remain in the groove portion.

したがって、溝部に水分や泥などが滞ることがなく、ランプレンズやフランジ部が透明素材であってもランプレンズの溝内面に設けられるローレットに不透明塗料を塗って、見えなくなるような作業が不要となった。   Therefore, moisture and mud are not stagnated in the groove, and even if the lamp lens and flange are made of a transparent material, it is not necessary to apply opaque paint to the knurled surface provided on the inner surface of the lamp lens groove so that it is not visible. became.

この発明の実施形態である自動車の外装ランプのフランジ部の構造について説明する。自動車のヘッドランプ、リアランプ、フォグランプ等の外装ランプは、外装側のランプレンズ1と車体側に設けられているランプハウジング2とを係合させており、その中に設けてあるライト3を光源として外部を照射する構造である。そして、ランプレンズ1とランプハウジング2との係合、ランプレンズ1からランプハウジング2方向へ突出する係合部10とランプハウジング2の一部が係合し、係合部10の端部の延長部としてフランジ部4が設けられており、フランジ部4近傍は図1及び図2に示すような構造である。   The structure of the flange part of the exterior lamp of the automobile according to the embodiment of the present invention will be described. Exterior lamps such as headlamps, rear lamps, and fog lamps for automobiles are configured such that a lamp lens 1 on the exterior side and a lamp housing 2 provided on the vehicle body side are engaged, and a light 3 provided therein is used as a light source. It is a structure that irradiates the outside. Then, the engagement between the lamp lens 1 and the lamp housing 2, the engagement portion 10 protruding from the lamp lens 1 toward the lamp housing 2, and a part of the lamp housing 2 are engaged, and the end of the engagement portion 10 is extended. The flange part 4 is provided as a part, and the flange part 4 vicinity has a structure as shown in FIG.1 and FIG.2.

外装ランプのフランジ部4とランプハウジング2との間に溝部5が形成される。この溝部5のフランジ部4の溝面側にローレット6を設けている。   A groove portion 5 is formed between the flange portion 4 of the exterior lamp and the lamp housing 2. A knurl 6 is provided on the groove surface side of the flange portion 4 of the groove portion 5.

ローレット6は、カマボコ型の多数のローレット凸部7を刻み溝8を挟んで隣接して並列させた形状であり、ローレット凸部7の方向は、溝部5の奥行き方向に向いて形成される。それぞれのローレット凸部7は、その長手方向に複数の凹部9を設けている。   The knurling 6 has a shape in which a large number of kamaboko-shaped knurling projections 7 are arranged adjacent to each other with the groove 8 interposed therebetween, and the direction of the knurling projection 7 is formed in the depth direction of the groove 5. Each knurled convex portion 7 is provided with a plurality of concave portions 9 in the longitudinal direction.

ローレット凸部7に設けられる凹部9は、隣接するローレット凸部7の凹部9と、ローレット凸部7の長手方向の位置において、同じ位置とはならず、互いに異なる位置に設けられている。   The concave portions 9 provided in the knurled convex portions 7 are not the same position in the longitudinal direction positions of the concave portions 9 of the adjacent knurled convex portions 7 and the knurled convex portions 7, and are provided at different positions.

ローレット凸部7に設けられ複数の凹部9のそれぞれは、図4に示すようにローレット凸部7の長手方向において等間隔に設けられるとともに、隣接する相互のローレット凸部7の複数の凹部9が、互いに隣接するローレット凸部7の2つの凹部9、9間のほぼ中央に位置することが望ましい。   As shown in FIG. 4, each of the plurality of recesses 9 provided on the knurled protrusion 7 is provided at equal intervals in the longitudinal direction of the knurled protrusion 7, and the plurality of recesses 9 of the adjacent knurled protrusions 7 are provided. Desirably, the knurled projections 7 adjacent to each other are located approximately at the center between the two recesses 9 and 9.

ローレット凸部7に設けられるそれぞれの凹部9は、図5に示されるように断面形状がU字型の溝として形成され、幅は0.5mmであり、ローレット凸部7の長手方向における凹部7と隣の凹部7の間隔は1.0mmである。   As shown in FIG. 5, each concave portion 9 provided in the knurled convex portion 7 is formed as a groove having a U-shaped cross section, has a width of 0.5 mm, and the concave portion 7 in the longitudinal direction of the knurled convex portion 7.
