Abstract

PROBLEM TO BE SOLVED: To prevent the breakage of a reflector even if impact due to a collision and the like is added to a vehicle.SOLUTION: On an attaching seat surface 4 of a recessed portion 3 formed on a rear bumper 1, the width of a lower end portion 6a of a bridging portion 6 is formed to be narrower than an upper end portion. Therefore, when the rear bumper 1 is resin-molded, a weld line is easy to be formed at the lower end portion 6a with the narrow width of the bridging portion 6, and the lower end portion 6a with the narrow width of the bridging portion 6 is forcibly made to be fragile to be easy to break first upon a collision, thereby preventing the breakage of a reflector.SELECTED DRAWING: Figure 3

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 location 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)。   2. Description of the Related Art Conventionally, when a reflector is attached to a rear bumper of a vehicle such as an automobile, a structure in which the reflector is attached so that the reflector itself forms the same surface as the surface of the rear bumper has been adopted (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 mounting structure described in Patent Document 1 described above, since the reflector is mounted so as to be flush with the rear bumper surface, if an impact is applied from the rear to the rear bumper due to a collision or the like, there is a stress escape space. Therefore, there is a problem that the reflector is easily damaged due to direct impact.

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 a reflector from being damaged even when an impact due to 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-described object, the reflector mounting structure of the present invention is a reflector mounting structure for mounting a reflector at a predetermined location of a vehicle. The reflector mounting structure is formed on a resin member constituting a vehicle body and a reflector mounting seat surface of the resin member. An opening that is smaller than the outer shape of the reflector, a bridge part that is integrally formed with the resin member so as to bridge to a facing part of the periphery of the opening, and the reflector that is provided in the bridge part is locked The bridge portion is formed with a partly narrow width.

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 bridge portion is integrally formed so as to bridge the opening peripheral portion formed in a resin member such as a rear bumper, and the width of the bridge portion is partially narrowed. Therefore, when a resin member is processed with a resin, a so-called weld line is easily formed in a narrow portion of the bridge portion, and the narrow portion of the bridge portion where the weld line is formed is weak in strength. become. Therefore, when an impact due to a collision is applied to the resin member in a state where the reflector is attached, stress concentrates on the narrow fragile portion of the bridge portion, and the fragile portion is broken to form a stress escape field. Thus, it is possible to avoid stress on the reflector, and it is possible to prevent the reflector from being damaged due to the stress applied to the reflector at the time of collision as in the conventional case.

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。   An embodiment in which the reflector mounting structure according to the present invention is applied to a rear bumper will be described in detail with reference to FIGS. Note that front and rear and left and right in the present embodiment mean front and rear and left and right as viewed in a seated state on the 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, recesses 3 that are recessed forward are formed in the left and right end portions to which the circular reflector 2 of the rear bumper 1 that is a resin member constituting the vehicle body is attached. A circular mounting seat surface 4 having a diameter slightly larger than the outer shape of 2 is formed by resin molding. At this time, when the rear bumper 1 is resin-molded, the mounting seat surface 4 of the recess 3 has a square shape opposite to the square-shaped first opening 5a smaller than the outer shape of the reflector 2 as shown in FIG. The second opening 5b is formed oppositely, and as a result, a bridge portion 6 is formed on the mounting seat surface 4 so as to bridge the opposite portions of the peripheral edges of the openings 5a and 5b, and the lower end of the bridge portion 6 is formed. The part is formed so that the width in the left-right direction is narrower than the upper end part. The reflector 2 is formed by bonding a main body portion 21 on the front surface side and a reflection portion 22 on the rear surface 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。   Further, in the center of the bridge portion 6, a locking hole (in the “locking portion” in the present invention) that is long in the left-right direction through which the central locking piece 2a integrally formed in the center of the front surface of the main body portion 21 of the reflector 2 is inserted. 8), and the left and right locking pieces 2b integrally formed at the front left and right ends of the main body 21 of the reflector 2, respectively, at the center left end of the first opening 5a and the center right end of the second opening 5b. , 2c are inserted in the longitudinally long cutouts 5a1 and 5b1, respectively, and the central locking hole 8 and the cutouts 5a1 and 5b1 are formed in the central locking piece 2a, the left locking piece 2b and the right of the reflector 2, respectively. The locking pieces 2c are inserted and locked respectively.

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。   By the way, the left and right engaging pieces 2b and 2c of the reflector 2 are formed with elastic engaging claws 9, and when the left engaging piece 2b and the right engaging piece 2c are inserted into the notches 5a1 and 5b1, The locking claws of the right locking pieces 2b and 2c are locked to the mounting seat surface 4 on the periphery of the notches 5a1 and 5b1, and further, as shown in FIG. 6 (a), the central locking piece 2a of the reflector 2 is transparent. A U-shaped pin 11 is inserted into the formed through hole 10, and the reflector 2 is attached in a locked state without the attachment seat surface 4 being detached.

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 rear bumper 1 is resin-molded by forming 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 recess 3 of the rear bumper 1, A so-called weld line is easily formed at the narrow bottom end 6a of the bridge portion 6, and the narrow bottom end 6a of the bridge portion 6 where the weld line is formed becomes weak in strength, and the rear bumper 1 When an impact due to a collision is applied, stress concentrates on the narrow lower end portion 6a of the brittle bridge portion 6 and breaks quickly. Therefore, before the stress at the time of collision is applied to the reflector 2, the narrow lower end portion 6 a of the bridge portion 6 is damaged, so that a stress escape field is formed and the reflector 2 is prevented from being damaged. .

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, when the rear bumper 1 is applied, the sprayed paint blows through the openings 5a and 5b. It is possible to paint evenly on the inner surface.

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 above-described embodiment, the impact due to the collision is applied to the vehicle 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 recess 3 of the rear bumper 1. In this case, the stress due to 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 the stress is not applied to the reflector 2. Thus, the reflector 2 can be prevented from being damaged.

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。   Further, since the openings 5a and 5b are formed in the mounting seat surface 4 of the recess 3 of the rear bumper 1, when painting the rear bumper 1, it is possible to form a blow-through path for the paint sprayed through the openings 5a and 5b. It is possible to paint evenly on the inner surface of the recess 3, 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 above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present 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 above-described embodiment, the case where the resin member in the present invention is the rear bumper 1 and the reflector 2 is attached to the rear bumper 1 has been described. However, 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。   In the above-described embodiment, the case where the width of the lower end portion 6a of the bridge portion 6 is made narrower than the upper end portion has been described. However, the resin material is injected into the mold in the resin molding of the resin member such as the rear bumper 1 or the like. Depending on the direction, the width of the upper end portion of the bridge portion 6 may be narrower than the lower end portion, and further the bridge portion 6 is formed in the left-right direction so that the width of the left end portion (or right end portion) is the right end portion. Of course, the width may be narrower than (or the left end portion), and it is only necessary that the width of a part of the bridge portion is 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 shape of the first and second openings 5a and 5b described above.
