Description

ランプの製造方法とその取付構造Lamp manufacturing method and mounting structure
　本発明は、ランプの製造方法に係り、特に、ハウジング及びレンズに形成されるダミー部が広く形成されたランプの製造方法とその取付構造に関する。 The present invention relates to a method for manufacturing a lamp, and more particularly to a method for manufacturing a lamp in which a dummy portion formed on a housing and a lens is widely formed and a mounting structure thereof.
　車両のランプは、開口部を有するハウジングと、開口部を覆うようにハウジングに取り付けられるレンズと、ハウジング及びレンズに形成されランプ機能を有せず意匠を向上させるためのダミー部（ランプにおける光らない部分）と、ハウジング及びレンズにより区画形成されたバルブ収容部に収容される光源としてのバルブとを備えている（例えば、特許文献１参照）。 A lamp of a vehicle includes a housing having an opening, a lens attached to the housing so as to cover the opening, and a dummy part formed on the housing and the lens for improving the design without having a lamp function (no light in the lamp Part) and a bulb as a light source housed in a bulb housing section defined by a housing and a lens (see, for example, Patent Document 1).
特開平１０－６４３０４号公報JP-A-10-64304
　車両のランプにおいては、ダミー部のレンズに対するオーバーハング（張り出し）が長くてハウジング及びレンズに十分な強度を確保できない場合がある。その場合、一般的に、スクリュー（ネジ）を用いて、ダミー部を形成する部分においてハウジングとレンズとを固定する方法が採用されている。しかしながら、この方法では、主に、スクリューボスが意匠面より見えてしまう、スクリュー分のコストアップ、及び、スクリュー組み付け分の工数アップという問題点がある。 In the lamp of the vehicle, there is a case where the overhang (protrusion) with respect to the lens of the dummy part is long and sufficient strength cannot be secured for the housing and the lens. In that case, generally, a method of fixing the housing and the lens at a portion where the dummy portion is formed by using a screw is adopted. However, in this method, there are mainly problems that the screw boss is visible from the design surface, the cost for the screw is increased, and the man-hour for the screw assembly is increased.
　そこで、本発明の目的は、意匠を損なうことなく、且つ、コストアップ及び工数アップを招くことなく、ランプのハウジング及びレンズに十分な強度を得ることができるランプの製造方法とその取付構造を提供することにある。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lamp manufacturing method and its mounting structure capable of obtaining sufficient strength for a lamp housing and a lens without impairing the design and without increasing costs and man-hours. There is to do.
　上述の目的を達成するために、本発明に係るランプの製造方法及び取付構造は、開口部を有するハウジングと、前記開口部を覆うように前記ハウジングに取り付けられるレンズと、前記ハウジング及び前記レンズにより形成されランプ機能を有しないダミー部とを備えるランプを製造する方法であって、前記ハウジングと前記レンズとを取り付ける工程において、前記開口部の縁部に沿った部分と前記ダミー部を形成する部分とを同時に溶着するものである。 In order to achieve the above object, a manufacturing method and a mounting structure of a lamp according to the present invention include a housing having an opening, a lens attached to the housing so as to cover the opening, and the housing and the lens. A method of manufacturing a lamp including a dummy portion that is formed and does not have a lamp function, wherein a portion along an edge of the opening and a portion that forms the dummy portion in the step of attaching the housing and the lens Are welded at the same time.
　また、前記ハウジングに前記開口部の縁部に沿ってハウジング側第一接合部を予め設けると共に、前記レンズに前記ハウジング側第一接合部と接合されるレンズ側第一接合部を予め設け、且つ、前記ハウジングに前記ダミー部を形成する部分に位置させてハウジング側第二接合部を予め設けると共に、前記レンズに前記ハウジング側第二接合部と接合されるレンズ側第二接合部を予め設け、前記レンズと前記ハウジングとを取り付ける工程において、前記ハウジング側第一接合部と前記レンズ側第一接合部とを溶着すると共に、前記ハウジング側第二接合部と前記レンズ側第二接合部とを溶着するものであっても良い。 In addition, a housing-side first joint is provided in advance along the edge of the opening in the housing, and a lens-side first joint that is joined to the housing-side first joint is provided in the lens in advance. In addition, a housing-side second joint portion is provided in advance in a position where the dummy portion is formed in the housing, and a lens-side second joint portion that is joined to the housing-side second joint portion is provided in the lens in advance. In the step of attaching the lens and the housing, the housing side first joint portion and the lens side first joint portion are welded, and the housing side second joint portion and the lens side second joint portion are welded. It may be what you do.
　本発明によれば、意匠を損なうことなく、且つ、コストアップ及び工数アップを招くことなく、ランプのハウジング及びレンズに十分な強度を得ることができるという優れた効果を奏する。 According to the present invention, there is an excellent effect that a sufficient strength can be obtained for the lamp housing and the lens without impairing the design and without increasing the cost and man-hours.

While abutting the junction 19 and the lens-side first junction 20, the housing-side second junction 22 of the housing-side dummy portion 16 a and the lens-side second junction 23 of the lens-side dummy portion 16 b are abutted. Simultaneously welding (for example, hot plate welding, ultrasonic welding, etc.). As a result, the housing-side first joint portion 19 and the lens-side first joint portion 20 provided on the lens 15 are welded to form a first weld portion 21, and the housing-side second joint portion 22 of the dummy portion 16 and the lens side are formed. The second welded portion 23 is welded to form the second welded portion 24 at the same time.
　次に、本実施形態の作用効果を説明する。 Next, the function and effect of this embodiment will be described.
　本実施形態では、ハウジング１４とレンズ１５とを溶着する工程において、開口部１３の縁部に沿った第一溶着部２１と、ダミー部１６を形成する第二溶着部２４とを同時に溶着するようにしている。このようにすることにより、スクリュー等の別部品を追加する必要がないので、コストアップを抑えることができると共に、スクリューの組み付け等の別工程を追加する必要もないので、工数アップを抑えることができる。なおかつ、第二溶着部２４によってダミー部１６を形成する部分において、ハウジング１４とレンズ１５とが固定されるので、ハウジング１４及びレンズ１５に十分な強度を得ることができる。 In the present embodiment, in the step of welding the housing 14 and the lens 15, the first welded portion 21 along the edge of the opening 13 and the second welded portion 24 forming the dummy portion 16 are welded simultaneously. I have to. By doing so, it is not necessary to add another part such as a screw, so that it is possible to suppress the cost increase, and it is not necessary to add another process such as assembly of the screw, thereby suppressing an increase in man-hours. it can. In addition, since the housing 14 and the lens 15 are fixed at the portion where the dummy portion 16 is formed by the second welded portion 24, sufficient strength can be obtained for the housing 14 and the lens 15.
　また、本実施形態によれば、スクリューを用いる場合（スクリューボスが意匠面より見える）と比較して第二溶着部２４は意匠上目立たなく、ランプ１０を車両後方から観た場合の外観上の品質（見栄え）が向上される。 Moreover, according to this embodiment, compared with the case where a screw is used (the screw boss is visible from the design surface), the second welded portion 24 is not conspicuous in design, and the appearance when the lamp 10 is viewed from the rear of the vehicle. Quality (appearance) is improved.
　以上、本発明の好適な実施形態について説明したが、本発明は上述の実施形態には限定されず他の様々な実施形態を採ることが可能である。 The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and various other embodiments can be adopted.
　例えば、上述の実施形態では、車両のリアコンビネーションランプについて説明したが、本発明はこれに限定されるものではない。 For example, in the above-described embodiment, the rear combination lamp of the vehicle has been described, but the present invention is not limited to this.
　また、第二溶着部２４の形状及び位置等は上述の実施形態には限定はされず、必要な強度等に応じて種々の形状及び位置等を採用することができる。デザイン自由度が大きく意匠をコントロールすることができるためである。一例として、図３及び図４に示すように、第二溶着部２４（ハウジング側第二接合部２２、レンズ側第二接合部２３）をハウジング１４の上側端及びレンズ１５の上側端に対してほぼ平行な方向に沿って複数本延設させることが考えられる。 Further, the shape and position of the second welded portion 24 are not limited to the above-described embodiment, and various shapes and positions can be adopted depending on the required strength and the like. This is because the design freedom is large and the design can be controlled. As an example, as shown in FIGS. 3 and 4, the second welded portion 24 (the housing-side second joint portion 22, the lens-side second joint portion 23) is connected to the upper end of the housing 14 and the upper end of the lens 15. It is conceivable to extend a plurality of wires along a substantially parallel direction.
