【考案の詳細な説明】
本考案は自動車等の車体のパネル制振構造に関し、その
目的は、車体閉断面部内での空胴共鳴の防止を図ったこ
とである。[Detailed Description of the Invention] The present invention relates to a panel vibration damping structure for a vehicle body such as an automobile, and its purpose is to prevent cavity resonance within a closed section of the vehicle body.
車体構造の中には内板と外板との２部材が空間を有して
閉断面を構成する部位が多い。In a vehicle body structure, there are many parts where two members, an inner plate and an outer plate, have a space and form a closed cross section.
長い閉断面部は、エンジンや回転部品からの振動を受け
て空胴共鳴を生ずる場合がある。A long closed cross section may generate cavity resonance due to vibrations from the engine or rotating parts.
この空胴共鳴は、パネルの振動波と空間内容積に基く固
有振動数が一致したときに発生することが解明されてい
る。It has been revealed that this cavity resonance occurs when the vibration waves of the panel match the natural frequency based on the volume of the space.
そして、この空胴共鳴を防止するために、従来では内板
と外板との間に直交する方向にフラット板を介装固着し
たり、断面コの字形のメンバを介装固着してパネルの制
振を行っていた。In order to prevent this cavity resonance, in the past, a flat plate was interposed and fixed in a direction perpendicular to the inner and outer panels, or a member with a U-shaped cross section was interposed and fixed to the panel. I was doing vibration control.
この場合、別個に制振部材を準備し、これを固設する組
付工数を要する不具合がある。In this case, there is a problem in that a vibration damping member is prepared separately and requires many man-hours to assemble it.
本考案はパネルとは別個の制振部材を必要とせず、内板
及び外板自体に制振部分を形成し、パネル組付と同時に
制振機能を具備すると共に、空間内の固有振動数を上げ
て共鳴点にずれを持たせ、空胴共鳴の発生を防止したこ
とを特長とするものである。This invention does not require a vibration damping member separate from the panel, and the vibration damping parts are formed on the inner and outer panels themselves, providing a damping function at the same time as the panel is assembled, and suppressing the natural frequency in the space. This is characterized by the fact that the resonance points are shifted to prevent the occurrence of cavity resonance.
以下本考案の実施例について図面により説明する。Embodiments of the present invention will be described below with reference to the drawings.

ネルアウタと接合されるパックパネルアウタで、車体の
内板と外板とに相当する部材であり、且つ空間５を有す
る閉断面を構成するものである。In Figures 1 and 3, 1 is a quarter panel inner, 2 is a quarter panel outer, 3 is a pack panel inner that is joined to the quarter panel inner 1, 4 is a pack panel outer that is joined to the quarter panel outer, and 4 is a pack panel outer that is joined to the quarter panel outer. It is a member corresponding to the inner plate and outer plate of , and constitutes a closed cross section having a space 5.
本考案は上記の構成において、内板及び外板端部を制振
部材として形成するものである。In the present invention, in the above structure, the inner plate and the outer plate end portions are formed as vibration damping members.
例えばクォータパネルアウタ２の端部とバックパネルイ
ンナ３の端部を、その長手方向に沿って相互に空間５内
に折曲して延設し、この延設端に隙間８を有して対向す
るフランジ６．７を折曲形威するものである。For example, the end of the quarter panel outer 2 and the end of the back panel inner 3 are bent and extended into the space 5 along their longitudinal direction, and are opposed to each other with a gap 8 at the extended ends. The flange 6.7 is bent.
尚上記の構成はクォータパネルインナ１とバックパネル
アウタ４との相互間で形成してもよい。Note that the above configuration may be formed between the quarter panel inner 1 and the back panel outer 4.
また、第２図に示すように、フランジ６．７が対向する
隙間８にブチルテープ等の軟質弾性材９を介在し、さら
に一層の制振効果を付与することも可能である。Furthermore, as shown in FIG. 2, a soft elastic material 9 such as butyl tape can be interposed in the gap 8 where the flanges 6.7 face each other to provide an even further vibration damping effect.
本考案は上記の通りの構造としたものであるから、内板
並びに外板は、空間５内に折曲して延設した延設端及び
延設端に折曲形成したフランジ６．７によって剛性が増
大され、この剛性増大によって内板並びに外板自体の制
振機能が高揚する。Since the present invention has the structure as described above, the inner plate and the outer plate are formed by an extending end bent and extending into the space 5 and a flange 6.7 formed by bending at the extending end. The stiffness is increased, and this increased stiffness enhances the vibration damping function of the inner and outer panels themselves.
また延設端のフランジ６．７を隙間８を持たせて対向さ
せ、あるいは隙間８間に軟質弾性材９を介在することに
よって内板、外板相互に振動を伝播することなく制振機
能を保持する。In addition, by arranging the flanges 6.7 at the extending ends to face each other with a gap 8, or by interposing a soft elastic material 9 between the gaps 8, a vibration damping function can be achieved without propagating vibrations between the inner and outer plates. Hold.
さらに加えて、延設端により空間５内を仕切り、空間５
内の容積を縮少する。In addition, the space 5 is partitioned by the extending end, and the space 5 is partitioned by the extension end.
Reduce the internal volume.
この空間５を複数の空間に区画する。This space 5 is divided into a plurality of spaces.
この空間５を複数の空間に区画することによって、各空
間５内の固有振動数が上がり、共鳴点にずれを生ヒさせ
るものである。By dividing this space 5 into a plurality of spaces, the natural frequency within each space 5 increases, causing a shift in the resonance point.
よって、制振機能を高揚した内板、外板のパネル振動数
と空間５内の固有振動波との周波数にずれが具現し、空
胴共鳴（気柱共鳴）の発生が抑制されるのである。Therefore, a difference occurs between the panel frequency of the inner and outer panels, which have enhanced vibration damping functions, and the natural vibration wave within the space 5, and the occurrence of cavity resonance (air column resonance) is suppressed. .

作業を省略することができる実益がある。As described above, the vehicle body panel allocating means according to the present invention extends the ends of the inner and outer panels constituting the vehicle body by bending them into a space along their longitudinal direction, with a gap between them. Since the rigidity of the panel is increased by bending the opposing flanges, a vibration damping structure is inevitably realized by the panel assembly work of the vehicle body, and by partitioning the space with the extending end, each Resonance can be prevented by increasing the natural frequency in the space and causing a shift in the resonance point, which has the practical benefit of omitting the conventional work of separately molding the vibration distribution parts and assembling them in a predetermined position. There is.
