本発明は、このような問題点に鑑みて、歩行者の保護と車両振動時のヘッドランプ取付強度確保を両立させた自動車用ヘッドランプの支持構造を提供することを目的とする。   In view of such problems, an object of the present invention is to provide a support structure for an automobile headlamp that achieves both protection of pedestrians and securing of headlamp mounting strength during vehicle vibration.

本発明は、この目的を達成するために、請求項１に記載の通り、下部車両取付部と上部車体取付部とを備えた自動車用ヘッドランプの支持部材において、前記上部車体取付部は帯板をなし、その長手方向と直交する方向にＶ字切欠等の薄肉の脆弱部を設け、前記上部車体取付部の長手方向に移動可能なカバーにて前記脆弱部を包囲し、前記カバーには前記脆弱部に係合してカバーを位置決めする位置決めピンと前記上部車体取付部に向けて延在する板バネとを備え、自動車用ヘッドランプの支持部材に強い応力が作用した時の前記上部車体取付部の変形による前記板バネの撓みにより前記カバーを脆弱部外へのスライドと同時に位置決めピンを破断させ、かつ脆弱部を破断させることにより前記自動車用ヘッドランプの支持部材に加わる強い応力を吸収するようにしたことを特徴とするものである。   In order to achieve this object, the present invention provides a vehicle headlamp support member having a lower vehicle mounting portion and an upper vehicle body mounting portion as claimed in claim 1, wherein the upper vehicle body mounting portion is a band plate. A thin fragile portion such as a V-shaped notch is provided in a direction orthogonal to the longitudinal direction, and the fragile portion is surrounded by a cover movable in the longitudinal direction of the upper vehicle body attachment portion. The upper vehicle body mounting portion when a strong stress is applied to a support member of an automobile headlamp, comprising a positioning pin that engages with the fragile portion to position the cover and a leaf spring extending toward the upper vehicle body mounting portion. Due to the bending of the leaf spring due to the deformation of the cover, the cover is slid out of the fragile portion and simultaneously the positioning pin is ruptured, and the fragile portion is ruptured to strongly apply to the support member of the automotive headlamp. It is characterized in that so as to absorb the force.

本発明によれば、通常では上部車体取付部の脆弱部をカバーによって補強しているため、車両振動時のヘッドランプ取付強度確保してヘッドランプの光軸のブレや取付部の破断等を解消し、歩行者がヘッドランプに衝突したときにはカバーを脆弱部外にスライドさせることにより脆弱部の破断で衝撃力を吸収して歩行者を保護するという歩行者の保護と車両振動時のヘッドランプ取付強度確保を両立させた効果を有している。   According to the present invention, since the weak part of the upper vehicle body mounting part is usually reinforced by the cover, the headlamp mounting strength during vehicle vibration is ensured to eliminate headlamp optical axis blurring and breakage of the mounting part. When the pedestrian collides with the headlamp, the cover is slid out of the fragile part to absorb the impact force by breaking the fragile part to protect the pedestrian and to attach the headlamp during vehicle vibration It has the effect of ensuring strength.

以下本発明を実施するための最良の形態について図面に基づいて説明する。図１において、１は自動車用ヘッドランプの支持部材（以下支持部材１と略称する）であり、左右一対の下部車両取付部２、３と帯板よりなる一つの上部車体取付部４とを備えている。この上部車体取付部４には図２で示すように、その長手方向と直交する方向にＶ字切欠等の薄肉の脆弱部５が設けられている。   The best mode for carrying out the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a support member (hereinafter abbreviated as a support member 1) for an automobile headlamp, and includes a pair of left and right lower vehicle attachment portions 2, 3 and one upper vehicle body attachment portion 4 formed of a strip. ing. As shown in FIG. 2, the upper vehicle body mounting portion 4 is provided with a thin fragile portion 5 such as a V-shaped notch in a direction orthogonal to the longitudinal direction.

本発明は上記上部車体取付部４の脆弱部５に補強用のカバー６を装着したことを特徴とするものである。このカバー６は図３で示すように、上部車体取付部４を挿通するための穴７が貫通されており、板バネ差し込み部８に差し込まれた板バネ９と、上面から穴７に向けて差し込まれた位置決めピン１０とを備えている。尚、カバー６は樹脂製が適当であり、位置決めピン１０は軸方向と直交する方向からのある応力が加わると破断するものである。   The present invention is characterized in that a reinforcing cover 6 is attached to the fragile portion 5 of the upper vehicle body attachment portion 4. As shown in FIG. 3, the cover 6 has a hole 7 through which the upper vehicle body mounting portion 4 is inserted, a leaf spring 9 inserted into the leaf spring insertion portion 8, and the hole 7 from the upper surface toward the hole 7. And a positioning pin 10 inserted therein. The cover 6 is suitably made of resin, and the positioning pin 10 is broken when a certain stress is applied from a direction orthogonal to the axial direction.

上部車体取付部４は図４で示すように、上記のカバー６の穴７を挿通して脆弱部５の部位で位置決めピン１０を脆弱部５に係合してカバー６で脆弱部５を包囲する。これにより上部車体取付部４の脆弱部５はカバーにより補強され強度を確保する。カバー６に設けられている板バネ９は上部車体取付部４に位置決めされた状態で図５で示すように、上部車体取付部４の下面に当接した状態となる。   As shown in FIG. 4, the upper vehicle body mounting portion 4 is inserted through the hole 7 of the cover 6, and the positioning pin 10 is engaged with the fragile portion 5 at the portion of the fragile portion 5 to surround the fragile portion 5 with the cover 6. To do. Thereby, the weak part 5 of the upper vehicle body attachment part 4 is reinforced by the cover to ensure strength. As shown in FIG. 5, the leaf spring 9 provided on the cover 6 is in contact with the lower surface of the upper vehicle body mounting portion 4 while being positioned on the upper vehicle body mounting portion 4.

本発明は上記の通りの構造であるから、通常では図５で示すように、カバー６は位置決めピン１０の部位で上下方向の応力Ｆ１，Ｆ２により脆弱部５の部位に位置して脆弱部５を補強している。従って、車両振動時のヘッドランプ取付強度確保してヘッドランプの光軸のブレや取付部の破断等をなくしヘッドランプを安定した状態で支持する。   Since the present invention has the structure as described above, normally, as shown in FIG. 5, the cover 6 is positioned at the position of the fragile portion 5 at the position of the positioning pin 10 by the vertical stresses F <b> 1 and F <b> 2. Is reinforced. Therefore, the headlamp mounting strength at the time of vehicle vibration is ensured, and the headlamp is supported in a stable state by eliminating blurring of the optical axis of the headlamp, breaking of the mounting portion, and the like.

また、歩行者がヘッドランプに衝突したときに支持部材１に図６で示すように強い応力Ｆ３が作用して上部車体取付部４が応力Ｆ３の作用方向に変形する。この上部車体取付部４の変形により上部車体取付部４に当接している板バネ９が撓みを生じ、カバー６は図７で示すように、板バネ９の撓みにより押されてスライドして脆弱部５の外へ移動し同時に位置決めピン１０を破断する。   Further, when the pedestrian collides with the headlamp, a strong stress F3 is applied to the support member 1 as shown in FIG. 6, and the upper vehicle body mounting portion 4 is deformed in the direction in which the stress F3 is applied. The deformation of the upper vehicle body mounting portion 4 causes the leaf spring 9 in contact with the upper vehicle body mounting portion 4 to bend, and the cover 6 is slid by being pushed by the bending of the leaf spring 9 as shown in FIG. It moves out of the part 5 and at the same time the positioning pin 10 is broken.

上記カバー６が板バネ９の撓みにより押されてスライドして脆弱部５の外へ移動することみより、カバー６による脆弱部５の補強作用がなくなり、上部車体取付部４の脆弱部５はが破断して強い応力Ｆ３を吸収し、歩行者が自動車用ヘッドランプに衝突したときの衝撃力を緩和して歩行者を保護するのである。   Since the cover 6 is pushed by the bending of the leaf spring 9 and slides and moves out of the weak part 5, the cover 6 has no reinforcing action on the weak part 5, and the weak part 5 of the upper vehicle body attachment part 4 Breaks and absorbs strong stress F3, and the impact force when the pedestrian collides with the automobile headlamp is relaxed to protect the pedestrian.

このように、本発明は、簡単な構造により、歩行者の保護と車両振動時のヘッドランプ取付強度確保を両立させた自動車用ヘッドランプの支持構造を提供することができる利点を有している。   As described above, the present invention has an advantage that it is possible to provide a support structure for an automobile headlamp that achieves both protection of pedestrians and securing of headlamp mounting strength during vehicle vibration with a simple structure. .
