Description
本発明は、自動車の樹脂製外板の表面に装飾部品を取り付ける際の取付構造に関するものである。 The present invention relates to a mounting structure for mounting decorative parts on the surface of a resin outer plate of an automobile.
自動車の各部が発生するノイズはできるだけ低減する試みが行われている。中でも走行時に発生する風切音については、発生する部分において対処的な解決方法が提案されている。例えば、特許文献１では、フロントフェンダーとＡピラーの割線から侵入する走行風によって生じる風切音を抑制するために、Ａピラー裏面にパッドを設定する構造が開示されている。 Attempts have been made to reduce noise generated in various parts of automobiles as much as possible. Above all, with regard to the wind noise generated during running, a coping solution has been proposed in the part where it is generated. For example, Patent Document 1 discloses a structure in which a pad is set on the back surface of the A pillar in order to suppress wind noise generated by a running wind entering from the split line of the front fender and the A pillar.
また、特許文献２では、リアドアガーニッシュの取付構造が提案されている。ここでは、リアドアアウタパネルと、リアドアガーニッシュの内側にリブが設けられ、そのリブとリアドアアウタパネルの間にパッドを弾接させる構造が開示されている。 Further, Patent Document 2 proposes a rear door garnish mounting structure. Here, a structure is disclosed in which a rear door outer panel and a rib are provided inside the rear door garnish, and a pad is repelled between the rib and the rear door outer panel.
車体のアウタパネルに装着する装飾部品による風切音は、装飾部品とアウタパネルとの隙間を風が通過することで発生する。したがって、風切音がしない程度に装飾部品とアウタパネル間の密閉性を高めることで抑制することができる。したがって、パッドを配置するというのは、解決方法の１つである。 The wind noise caused by the decorative parts attached to the outer panel of the vehicle body is generated when the wind passes through the gap between the decorative parts and the outer panel. Therefore, it can be suppressed by increasing the airtightness between the decorative parts and the outer panel to the extent that there is no wind noise. Therefore, arranging pads is one of the solutions.
しかし、パッド部材を用いると、パット材の反力によって設定部品の組付け作業性が低下してしまうという課題があった。またパッド材を用意する必要があることと、それを貼り付ける工程が必要になるため、部品の増加、および工程の増加という原価上昇の要因となる。 However, when the pad member is used, there is a problem that the workability of assembling the set parts is lowered due to the reaction force of the pad material. In addition, since it is necessary to prepare a pad material and a process of attaching the pad material is required, it becomes a factor of cost increase such as an increase in parts and an increase in processes.
本発明は上記の課題に鑑みて想到されたものであり、部品増加や工程増加することなく、取付部品からの風切音を抑制する構造を提供するものである。 The present invention has been conceived in view of the above problems, and provides a structure that suppresses wind noise from mounting parts without increasing the number of parts or processes.
より具体的に本発明に係る装飾部品取付構造は、
樹脂外板部品の表面に装飾部品を取りつける取付構造であって、
前記樹脂外板部品の表面の装飾部品が取りつけられる領域に設けられた凹み部と、
前記凹み部の底に前記装飾部品の裏面に向けて、前記装飾部品の上下方向に渡って膨出されたビードを有し、
前記ビードは、車体の走行風の流れ方向に対して略直交するように形成され、
前記ビード頂部と前記装飾部品の裏面は、所定寸法の隙間を有することを特徴とする。
More specifically, the decorative component mounting structure according to the present invention is
It is a mounting structure that attaches decorative parts to the surface of resin outer panel parts.
A recess provided in the area where the decorative part on the surface of the resin outer plate part is attached, and
The bottom of the recess has a bead that bulges in the vertical direction of the decorative part toward the back surface of the decorative part .
The bead is formed so as to be substantially orthogonal to the flow direction of the traveling wind of the vehicle body.
The top of the bead and the back surface of the decorative part are characterized by having a gap of a predetermined dimension.
本発明に係る装飾部品取付構造は、部品同士の干渉による異音を発生させることなく、アウタパネル（外板部品）と装飾部品との隙間に侵入した走行風の流速を低減させ、風切
音を抑制することができる。
The decorative component mounting structure according to the present invention reduces the flow velocity of the running wind that has entered the gap between the outer panel (outer panel component) and the decorative component without generating abnormal noise due to interference between the components, and produces wind noise. It can be suppressed.
また、ビードの形成による樹脂外板部品の形状剛性が向上するので、樹脂外板部品の薄肉化が可能となり、車体の重量軽減と原価低減を図ることができる。 Further, since the shape rigidity of the resin outer plate component is improved by forming the bead, the thickness of the resin outer plate component can be reduced, and the weight of the vehicle body and the cost can be reduced.
以下に本発明に係る装飾部品取付構造について図面を用いながら説明を行う。なお、以下の説明は本発明の一実施形態を例示するものであり、本発明は以下の説明に限定されない。したがって、以下の説明は本発明の趣旨を逸脱しない限りにおいて改変することができる。なお、本明細書において矢印Ｆｒは車体前方向を示し、矢印Ｒｒは車体後方向を示すものとする。 Hereinafter, the decorative component mounting structure according to the present invention will be described with reference to the drawings. The following description illustrates one embodiment of the present invention, and the present invention is not limited to the following description. Therefore, the following description can be modified without departing from the spirit of the present invention. In the present specification, the arrow Fr indicates the vehicle body front direction, and the arrow Rr indicates the vehicle body rear direction.
図１に本発明に係る装飾部品取付構造１を適用した部分の外観を示す。図１は車体の前方部分であって、フロントドア１０とＡピラー１２および樹脂製のフェンダ１４の突合せ部分を示す。この突合せ部分の略三角形領域に三角ガジェットと呼ばれる装飾部品２５を装着する。本発明に係る装飾部品取付構造１では、この略三角形領域にビード１８を形成する。 FIG. 1 shows the appearance of a portion to which the decorative component mounting structure 1 according to the present invention is applied. FIG. 1 is a front portion of the vehicle body, and shows a butt portion between the front door 10, the A pillar 12, and the resin fender 14. A decorative part 25 called a triangular gadget is attached to a substantially triangular region of the butt portion. In the decorative component mounting structure 1 according to the present invention, the bead 18 is formed in this substantially triangular region.
図２には、図１のＡ−Ａ断面図を示す。フェンダ１４には、装飾部品２５を配置するための凹み部２０が形成される。装飾部品２５を取り付けた際に、装飾部品２５と、フェンダ１４のアウタパネル１４ａ（以後「フェンダアウタパネル１４ａ」と呼ぶ。）がほぼ面一になるようにするためである。また、フェンダアウタパネル１４ａと、装飾部品２５との間は、爪嵌合等で固定される。したがって、図示していないが、そのための爪および嵌合部が、装飾部品２５の裏面２５ｂ側と、フェンダアウタパネル１４ａに設けられている。 FIG. 2 shows a cross-sectional view taken along the line AA of FIG. A recess 20 for arranging the decorative component 25 is formed on the fender 14. This is so that when the decorative component 25 is attached, the decorative component 25 and the outer panel 14a of the fender 14 (hereinafter referred to as "fender outer panel 14a") are substantially flush with each other. Further, the fender outer panel 14a and the decorative part 25 are fixed by claw fitting or the like. Therefore, although not shown, claws and fitting portions for that purpose are provided on the back surface 25b side of the decorative component 25 and on the fender outer panel 14a.
凹み部２０の底２０ａには装飾部品２５の裏面２５ｂに向かって膨出するビード１８が形成される。ビード１８は、装飾部品２５の裏面２５ｂに当接しない高さに設定する。したがって、ビード１８の頂部１８ｔと装飾部品２５の裏面２５ｂとの間には所定寸法の隙間２６が形成される。ここで所定寸法の隙間２６とは、およそ０．５ｍｍから２ｍｍである。装飾部品２５の剛性が高ければ、隙間２６は小さくしてもよい。装飾部品２５は、ほぼ振動しないとみなせるからである。 A bead 18 that bulges toward the back surface 25b of the decorative part 25 is formed on the bottom 20a of the recessed portion 20. The bead 18 is set at a height that does not abut on the back surface 25b of the decorative component 25. Therefore, a gap 26 having a predetermined size is formed between the top portion 18t of the bead 18 and the back surface 25b of the decorative component 25. Here, the gap 26 having a predetermined dimension is about 0.5 mm to 2 mm. If the rigidity of the decorative part 25 is high, the gap 26 may be made small. This is because the decorative part 25 can be regarded as hardly vibrating.
一方、装飾部品２５の剛性が低い場合は、隙間２６を広めに取っておくことが必要である。剛性の少ない板状の装飾部品２５は、２次元振動を生じビード１８の頂部１８ｔと接触する可能性があるからである。 On the other hand, when the rigidity of the decorative part 25 is low, it is necessary to set aside a wide gap 26. This is because the plate-shaped decorative component 25 having low rigidity may generate two-dimensional vibration and come into contact with the top 18t of the bead 18.
走行によってフェンダアウタパネル１４ａと装飾部品２５の間に侵入してきた空気の流れは、ビード１８によって生じた大きな空気抵抗によって流速が低減される。したがって、風切音が抑制されることとなる。 The flow velocity of the air flow that has entered between the fender outer panel 14a and the decorative component 25 due to running is reduced by the large air resistance generated by the bead 18. Therefore, the wind noise is suppressed.
また、ビード１８と装飾部品２５は走行中の振動が加わっても接触しない隙間２６が設けられているので、ビード１８と装飾部品２５同士が干渉することで異音が発生することも抑制される。さらに、ビード１８は剛性向上形状（リブ）ともみなせるので、ビード１８を配置する付近のフェンダアウタパネル１４ａ自体の剛性が向上する。したがって、その付近については、フェンダアウタパネル１４ａ等の板厚を薄くすることができるという
効果もある。
Further, since the bead 18 and the decorative component 25 are provided with a gap 26 that does not come into contact with each other even when vibration during traveling is applied, it is possible to suppress the generation of abnormal noise due to the interference between the bead 18 and the decorative component 25. .. Further, since the bead 18 can be regarded as a rigidity-improved shape (rib), the rigidity of the fender outer panel 14a itself in the vicinity where the bead 18 is arranged is improved. Therefore, there is also an effect that the thickness of the fender outer panel 14a or the like can be reduced in the vicinity thereof.
ビード１８の形成位置は、装飾部品２５の形状によってさまざまに設定することができる。しかし好ましくは凹み部２０の底２０ａにおいて、車体前方側に設けるのが好ましい。フェンダアウタパネル１４ａと装飾部品２５の取付隙間３０から侵入する走行風を効果的に減速させることができるからである。 The formation position of the bead 18 can be variously set depending on the shape of the decorative part 25. However, it is preferable that the bottom 20a of the recessed portion 20 is provided on the front side of the vehicle body. This is because the traveling wind entering through the mounting gap 30 between the fender outer panel 14a and the decorative component 25 can be effectively reduced.
再度図１を参照する。ビード１８の設定角度θは、凹み部２０を車体前後方向に分割できれば足りる。より具体的には、垂直方向から±６０度の角度で設けるのが好ましい。これは車体の走行風の流れ方向に対して略直交するような角度であると言ってもよい。 See FIG. 1 again. The setting angle θ of the bead 18 is sufficient if the recess 20 can be divided in the front-rear direction of the vehicle body. More specifically, it is preferably provided at an angle of ± 60 degrees from the vertical direction. It can be said that this is an angle that is substantially orthogonal to the flow direction of the traveling wind of the vehicle body.
フェンダアウタパネル１４ａに設けられるビード１８は、装飾部品２５の上下方向に渡って設けられているのが望ましい。ここで「上下方向に渡って設ける」とは、ビード１８を設けた位置で、装飾部品２５の下辺から上辺までの高さ（垂直長さ）の７０％以上に渡って配置されていると言ってよい。フェンダアウタパネル１４ａと装飾部品２５との間３０とを通過する走行風の風速を低減させるのが目的だからである。また、凹み部２０に複数本のビード１８が設けられていてもよい。１本のビード１８だけでは効果がない場合もあるからである。 The bead 18 provided on the fender outer panel 14a is preferably provided in the vertical direction of the decorative part 25. Here, "providing in the vertical direction" means that the bead 18 is provided at a position and is arranged over 70% or more of the height (vertical length) from the lower side to the upper side of the decorative part 25. You can. This is because the purpose is to reduce the wind speed of the traveling wind passing between the fender outer panel 14a and the decorative component 25. Further, a plurality of beads 18 may be provided in the recessed portion 20. This is because one bead 18 alone may not be effective.
図３には、ビード１８を複数本形成した場合の例を示す。ビード１８を複数本配置する場合は、全てのビード１８を凹み部２０の上下方向に渡って形成される場合（図３（ａ））だけでなく、オリフィス形状に配置してもよい（図３（ｂ））。すなわち、「上下方向に渡って設ける」とは、車体前後方向で最も後側のビード１８からみて、それより前のビード１８によって、上下方向に渡って形成されていることを含む。 FIG. 3 shows an example in which a plurality of beads 18 are formed. When a plurality of beads 18 are arranged, not only when all the beads 18 are formed in the vertical direction of the recess 20 (FIG. 3A), but also in an orifice shape (FIG. 3). (B)). That is, "providing in the vertical direction" includes that the bead 18 is formed in the vertical direction by the bead 18 in front of the bead 18 on the rearmost side in the front-rear direction of the vehicle body.
以上のように、本発明に係る装飾部品取付構造１は、装飾部品２５を取り付ける相手部材（ここではフェンダ１４）が樹脂製であれば、幅数ミリといった細かい小さな形状のビード１８も容易に形成することができ、低コストで異音抑制に効果的な構造である。 As described above, in the decorative component mounting structure 1 according to the present invention, if the mating member (here, the fender 14) to which the decorative component 25 is mounted is made of resin, a bead 18 having a small shape having a width of several millimeters can be easily formed. It is a structure that can be used and is effective in suppressing abnormal noise at low cost.
本発明は、自動車の外板部品に装着する装飾部品の取付構造に好適に利用することができる。 INDUSTRIAL APPLICABILITY The present invention can be suitably used for a mounting structure of decorative parts to be mounted on the outer panel parts of an automobile.
