Description

本発明は、車両の所定箇所にリフレクタを取り付けるリフレクタ取付構造に関する。   The present invention relates to a reflector mounting structure for mounting a reflector at a predetermined position of a vehicle.

従来、自動車等の車両のリアバンパーにリフレクタを取り付ける場合において、見栄えをよくするために、リフレクタ自体がリアバンパー表面と同一面を形成すべくリフレクタを取り付ける構造が採用されている（特許文献１参照）。   Conventionally, when attaching a reflector to a rear bumper of a vehicle such as an automobile, in order to improve appearance, a structure is adopted in which the reflector is attached so that the reflector itself forms the same surface as the rear bumper surface (see Patent Document 1) ).

特開２０１２−２４０５４１号公報（段落００２１〜００２３および図１〜図３）JP 2012-240541 A (paragraphs 0021 to 0023 and FIGS. 1 to 3)

しかし、上記した特許文献１に記載のリフレクタ取付構造の場合、リフレクタがリアバンパー表面と同一面を成すように取り付けられるため、衝突等によって例えばリアバンパーに後方から衝撃が加わると、応力の逃げ場がないことから、リフレクタにも直接衝撃が加わってリフレクタが容易に破損するという問題がある。   However, in the case of the reflector attachment structure described in Patent Document 1 described above, the reflector is attached so as to be flush with the rear bumper surface, so if, for example, an impact is applied to the rear bumper from the rear due to a collision etc. Since the reflector is not directly impacted, the reflector is easily damaged.

本発明は、衝突等による衝撃が車両に加わっても、リフレクタが破損することを防止できるようにすることを目的とする。   An object of the present invention is to prevent the reflector from being damaged even if an impact caused by a collision or the like is applied to a vehicle.

上記した目的を達成するために、本発明のリフレクタ取付構造は、車両の所定箇所にリフレクタを取り付けるリフレクタ取付構造において、車体を構成する樹脂部材と、前記樹脂部材のリフレクタ取付座面に形成された前記リフレクタの外形よりも小なる開口と、前記開口の周縁の対向部分に橋渡しするように前記樹脂部材に一体形成された橋設部と、前記橋設部に設けられて前記リフレクタが係止状態に取り付けられる係止部とを備え、前記橋設部の幅が、一部狭く形成されていることを特徴としている。   In order to achieve the above object, the reflector mounting structure of the present invention is a reflector mounting structure for mounting a reflector at a predetermined place of a vehicle, and is formed on a resin member constituting a vehicle body and a reflector mounting surface of the resin member. An opening smaller than the outer shape of the reflector, a bridge portion integrally formed with the resin member so as to bridge to an opposing portion of the periphery of the opening, and the bridge portion provided with the reflector And a locking portion attached to the wall, and a width of the bridge portion is formed to be partially narrow.

本発明によれば、例えばリアバンパーなどの樹脂部材に形成された開口周縁の対向部分に、橋設部が橋渡しするように一体形成され、この橋設部の幅が一部狭く形成されているため、樹脂部材を樹脂成形加工する際に、橋設部の幅の狭い部分にいわゆるウェルドラインが形成され易くなり、このウェルドラインが形成される橋設部の幅の狭い部分が強度的に脆弱になる。そのため、リフレクタが取り付けられた状態において、樹脂部材に衝突による衝撃が加わった場合に、橋設部の幅の狭い脆弱部分に応力が集中して当該脆弱部分が破損して応力の逃げ場が形成され、リフレクタに応力がかかるのを回避することができ、従来のようにリフレクタに衝突時の応力が加わることによるリフレクタの破損を防止することが可能になる。   According to the present invention, for example, the bridging portion is integrally formed so as to bridge over the facing portion of the opening peripheral edge formed in the resin member such as the rear bumper, and the width of the bridging portion is partially narrowed Therefore, when resin-molding the resin member, a so-called weld line is easily formed in the narrow portion of the bridge portion, and the narrow portion of the bridge portion on which the weld line is formed is fragile in strength become. Therefore, in a state where the reflector is attached, when an impact due to a collision is applied to the resin member, the stress is concentrated on the narrow fragile portion of the bridge portion, the fragile portion is broken, and a stress relief space is formed. The stress on the reflector can be avoided, and it is possible to prevent the damage of the reflector due to the stress at the time of collision being applied to the reflector as in the prior art.

本発明に係るリフレクタ取付構造をリアバンパーに適用した一実施形態について、図１ないし図６を参照して詳細に説明する。なお、本実施形態でいう前後、左右とはシートに着座した状態で見た前後、左右を意味する。   One embodiment in which a reflector mounting structure according to the present invention is applied to a rear bumper will be described in detail with reference to FIGS. 1 to 6. In the present embodiment, front and rear, left and right mean front, rear, left and right as viewed in a state of being seated on a seat.

図１に示すように、車体を構成する樹脂部材であるリアバンパー１の円形状を成すリフレクタ２が取り付ける左右端部に前方に窪む凹部３が加工形成され、この凹部３の奥にはリフレクタ２の外形よりもやや大きい直径を有する円形状の取付座面４が、樹脂成型により形成される。このとき、リアバンパー１の樹脂成形時に、凹部３の取付座面４には、図３に示すようにリフレクタ２の外形よりも小なるく字状の第１開口５ａと逆向きのく字状の第２開口５ｂとが対向して形成され、結果的に、両開口５ａ，５ｂ周縁の対向部分を橋渡しするように橋設部６が取付座面４に形成され、橋設部６の下端部は、上端部に比べて左右方向の幅が狭くなるように形成される。なお、リフレクタ２は前面側の本体部２１と後面側の反射部２２とが貼り合されて形成されている。   As shown in FIG. 1, recessed portions 3 recessed forward are formed at the left and right end portions to which the circular reflectors 2 of the rear bumper 1 which is a resin member constituting the vehicle body are attached. A circular mounting seat 4 having a diameter slightly larger than the outer diameter of 2 is formed by resin molding. At this time, at the time of resin molding of the rear bumper 1, the mounting seat surface 4 of the recess 3 has a V-shape opposite to the V-shaped first opening 5a smaller than the outer shape of the reflector 2 as shown in FIG. The bridge portion 6 is formed on the mounting seat surface 4 so as to bridge the opposing portions of the peripheries of both the openings 5a and 5b, and the lower end of the bridge portion 6 is consequently formed. The portion is formed so that the width in the left-right direction is narrower than the upper end portion. The reflector 2 is formed by bonding the main body portion 21 on the front side and the reflecting portion 22 on the rear side.

さらに、橋設部６の中央にはリフレクタ２の本体部２１の前面中央に一体形成された中央係止片２ａが挿通される左右方向に長い係止孔（本発明における「係止部」に相当）８が形成され、第１開口５ａの中央左端および第２開口５ｂの中央右端には、それぞれリフレクタ２の本体部２１の前面左、右端部に一体形成された左、右係止片２ｂ，２ｃが挿通される縦方向に長い切欠部５ａ１，５ｂ１がそれぞれ形成され、中央の係止孔８、切欠部５ａ１，５ｂ１に、リフレクタ２の中央係止片２ａ、左係止片２ｂ、右係止片２ｃがそれぞれ挿入されて係止するようになっている。   Furthermore, in the center of the bridging portion 6, a locking hole which is long in the left-right direction (a "locking portion" in the present invention) is inserted through which a central locking piece 2a integrally formed at the front center of the main body 21 Equivalent) 8 are formed, and left and right locking pieces 2b integrally formed on the front left and right ends of the main body 21 of the reflector 2 at the center left end of the first opening 5a and the center right end of the second opening 5b, respectively. , 2c are inserted in the longitudinal direction of the notch 5a1, 5b1 is formed in the longitudinal direction, the central locking hole 8, the notch 5a1, 5b1, the central locking piece 2a of the reflector 2, the left locking piece 2b, the right The locking pieces 2c are respectively inserted and locked.

ところで、リフレクタ２の左、右係止片２ｂ，２ｃには弾性を有する係止爪９が形成され、左係止片２ｂ、右係止片２ｃを切欠部５ａ１，５ｂ１に挿通すると、左、右係止片２ｂ，２ｃの係止爪が切欠部５ａ１，５ｂ１の周縁の取付座面４に係止し、さらに図６（ａ）に示すように、リフレクタ２の中央係止片２ａに透設された透孔１０にコ字状のピン１１が挿入され、リフレクタ２が取付座面４の脱離することなく係止状態に取り付けられる。   The left and right locking pieces 2b and 2c of the reflector 2 are formed with locking lugs 9 having elasticity, and when the left locking piece 2b and the right locking piece 2c are inserted into the notches 5a1 and 5b1, the left The locking claws of the right locking pieces 2b and 2c lock onto the mounting seating surface 4 at the periphery of the notches 5a1 and 5b1, and as shown in FIG. 6A, the central locking piece 2a of the reflector 2 is transparent. The U-shaped pin 11 is inserted into the through hole 10 provided, and the reflector 2 is attached in a locked state without detachment of the mounting surface 4.

このように、リアバンパー１の凹部３の取付座面４において、橋設部６の下端部６ａの幅が上端部よりも狭く形成されることにより、リアバンパー１を樹脂成形加工する際に、橋設部６の幅の狭い下端部６ａにいわゆるウェルドラインが形成され易くなり、このウェルドラインが形成される橋設部６の幅の狭い下端部６ａが強度的に脆弱になり、リアバンパー１に衝突による衝撃が加わったときに、脆弱な橋設部６の幅の狭い下端部６ａに応力が集中していち早く破損する。そのため、リフレクタ２に衝突時の応力が加わる前に橋設部６の幅の狭い下端部６ａが破損することにより、応力の逃げ場が形成されてリフレクタ２の破損が未然に防止されることになる。   Thus, when the width of the lower end portion 6a of the bridge portion 6 is narrower than the upper end portion in the mounting seat surface 4 of the concave portion 3 of the rear bumper 1, when the rear bumper 1 is resin-molded, A so-called weld line is easily formed at the narrow lower end portion 6 a of the bridge portion 6, and the narrow lower end portion 6 a of the bridge portion 6 where the weld line is formed becomes weak in strength. When an impact due to a collision is applied, stress concentrates on the narrow lower end portion 6a of the fragile bridge portion 6 and is rapidly damaged. Therefore, when the narrow lower end portion 6a of the bridging portion 6 is broken before stress is applied to the reflector 2 at the time of collision, a relief space for stress is formed and breakage of the reflector 2 is prevented in advance. .

また、リアバンパー１の凹部３の取付座面４に開口５ａ，５ｂを形成することにより、リアバンパー１を塗装する際に、噴霧される塗料が開口５ａ，５ｂを吹き抜けることになり、凹部３の内面までむらなく塗装することができる。   Further, by forming the openings 5a and 5b in the mounting seat surface 4 of the recess 3 of the rear bumper 1, the paint to be sprayed will blow through the openings 5a and 5b when the rear bumper 1 is coated. Even the inner surface of can be painted evenly.

したがって、上記した実施形態によれば、リアバンパー１の凹部３の取付座面４において、橋設部６の下端部６ａの幅を上端部よりも狭くすることにより、車両に衝突による衝撃が加わった場合に、橋設部６の幅の狭い下端部６ａに衝突による応力を集中させることができ、橋設部６の下端部６ａが先に破損するため、リフレクタ２に応力がかかることを回避してリフレクタ２の破損を未然に防止することができる。   Therefore, according to the embodiment described above, by making the width of the lower end portion 6a of the bridge portion 6 narrower than the upper end portion in the mounting seat surface 4 of the concave portion 3 of the rear bumper 1, an impact due to a collision is applied to the vehicle. In this case, the stress caused by the collision can be concentrated on the narrow lower end portion 6a of the bridge portion 6, and the lower end portion 6a of the bridge portion 6 is damaged first, so that stress on the reflector 2 is avoided. Thus, damage to the reflector 2 can be prevented in advance.

また、リアバンパー１の凹部３の取付座面４に開口５ａ，５ｂを形成したため、リアバンパー１を塗装する際に、開口５ａ，５ｂを介して噴霧される塗料の吹き抜け路を形成することができ、凹部３の内面までむらなく塗装することが可能になり、意匠的な見栄えの向上を図ることができる。   In addition, since the openings 5a and 5b are formed in the mounting seat surface 4 of the recess 3 of the rear bumper 1, when the rear bumper 1 is coated, a blowout path of the paint sprayed through the openings 5a and 5b can be formed. Thus, the inner surface of the recess 3 can be evenly coated, and the design appearance can be improved.

なお、本発明は上記した実施形態に限定されるものではなく、その趣旨を逸脱しない限りにおいて上述したもの以外に種々の変更を行なうことが可能である。   The present invention is not limited to the embodiment described above, and various modifications can be made other than the above without departing from the scope of the invention.

例えば、上記した実施形態では、本発明における樹脂部材をリアバンパー１とし、リアバンパー１にリフレクタ２を取り付ける場合について説明したが、本発明に係るリフレクタ取付構造はリアバンパー１以外にも適用することが可能であり、本発明における樹脂部材はリアバンパーに限定されるものではない。   For example, in the embodiment described above, the resin member in the present invention is used as the rear bumper 1 and the reflector 2 is attached to the rear bumper 1, but the reflector mounting structure according to the present invention is applied to other than the rear bumper 1. The resin member in the present invention is not limited to the rear bumper.

また、上記した実施形態では、橋設部６の下端部６ａの幅を上端部よりも狭くした場合について説明したが、リアバンパー１等の樹脂部材の樹脂成型における樹脂材の金型への注入方向に応じて、橋設部６の上端部の幅を下端部よりも狭くしてもよく、さらには左右方向に橋設部６を形成して左端部（または右端部）の幅を右端部（または左端部）よりも狭くしてもよいのは勿論であり、要するに橋設部の一部の幅が狭く形成されていればよい。   Moreover, although the above-mentioned embodiment demonstrated the case where the width of the lower end part 6a of the bridging part 6 was made narrower than the upper end part, injection to the metal mold of the resin material in resin molding of resin members, such as rear bumper 1 grade | etc. Depending on the direction, the width of the upper end of the bridge portion 6 may be narrower than that of the lower end, and furthermore, the bridge portion 6 is formed in the left-right direction and the width of the left end (or right end) is the right end Of course, it may be narrower than (or the left end portion), and in short, the width of a part of the bridge portion may be formed narrow.

また、開口の形状は、上記した第１、第２開口５ａ，５ｂの形状に限るものではない。   Further, the shape of the opening is not limited to the shapes of the first and second openings 5a and 5b described above.
