Abstract
Description
また、従来の車両のフロアパネル構造は、フロアパネル100の局所的な補強に過ぎず、曲面形状の膨出部101と直線形状の車体構造部材103及びビード102とが無関係に配置され、これら膨出部101と車体構造部材103及びビード102とに挟まれた位置の平面部が変形し、膨出部101の角部を持ち上げるような振動モードが発生し、特定の周波数帯における上下振動等を生じるおそれがあるので、要求されるフロアパネル100の振動抑制性能や車室内騒音の低減性能を十分に確保することができないという問題があった。 However, in the conventional vehicle floor panel structure described above, since the
In addition, the conventional vehicle floor panel structure is merely a local reinforcement of the
図1~図7は本発明の実施形態に係る車両のフロアパネル構造を示すものである。なお、図1及び図2において、矢印F方向は車両前方を示している。 Hereinafter, the present invention will be described in detail based on illustrated embodiments.
1 to 7 show a vehicle floor panel structure according to an embodiment of the present invention. 1 and 2, the direction of arrow F indicates the front of the vehicle.
膨出部5,6,7,8は、それぞれ車両下方へ向かって突出するように膨出し、底面部5a,6a,7a,8a及び縦壁部5b,6b,7b,8bを有する断面略コ字状に形成されており、車両幅方向及び車両前後方向に間隔空けて配置されている。一方、ビード9は、車両上方へ向かって突出するように膨出し、上面部9a及び縦壁部9bを有する断面略コ字状に形成されている。すなわち、膨出部5,6,7,8とビード9とは、互いに反対方向へ膨出するように形成されている。 Furthermore, in the floor panel structure of the present embodiment,
The bulging
また、膨出部5,6,7,8の車両上下方向の断面は、底面部5a,6a,7a,8aの側端部と縦壁部5b,6b,7b,8bの下端部との間が曲面形状に形成されている。
このような断面形状の膨出部5,6,7,8がフロアパネル1に設けられていることにより、フロアパネル1の剛性が高められ、フロアパネル1の振動抑制効果が強化されるようになっている。 As shown in FIG. 7, the boundary portions between the
Further, the cross section of the bulging
By providing the bulging
したがって、本実施形態のフロアパネル構造によれば、追加の制振部材、補強部材等を使用せずに、フロアパネル1の剛性が確保されているので、重量及び部品点数の増加やコスト高を招くことなく、膨出部5,6,7,8の角部52,62,72,82自体の振動を低減でき、膨出部5,6,7,8の角部52,62,72,82を起点とするフロアパネル1の振動を効果的に抑えることができ、車室内の騒音を低減させることができる。 As described above, in the vehicle floor panel structure according to the embodiment of the present invention, the
Therefore, according to the floor panel structure of the present embodiment, since the rigidity of the
例えば、既述の実施の形態では、膨出部5,6,7,8が車両下方へ向かって膨出し、ビード9が車両上方へ向かって膨出しているが、膨出部5,6,7,8が車両上方へ向かって膨出し、ビード9が車両下方へ向かって膨出するように形成されていても良い。また、既述の実施の形態のビード9は車両幅方向へ沿って延在しているが、ビード9が車両前後方向へ沿って延在している場合にも、適用することができる。 While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.
For example, in the above-described embodiment, the bulging
