Description

本発明は、例えば燃料タンク等、床下に設けられた付属機器にアクセスするための点検口を備える車体のフロアパネルに関するものである。   The present invention relates to a floor panel of a vehicle body having an inspection port for accessing an accessory device provided under the floor such as a fuel tank.

自動車の燃料タンクは、リアシートの下方など、床下に配設されるが、燃料タンクに設けられるバルブ類やポンプ等の付属機器の保守・整備性を確保するために、着脱自在な蓋で閉じた点検口をフロアパネルに設けることがある。   The fuel tank of an automobile is placed under the floor, such as under the rear seat, but closed with a detachable lid to ensure the maintenance and maintainability of valves and pumps and other accessories provided in the fuel tank. An inspection opening may be provided on the floor panel.

他方、車体のフロアパネルには、車体の捩れや振動抑制、側面衝突時の衝撃からの車室の保護などを目的として、車体幅方向に延びる強度部材（クロスメンバ）が設けられている（特許文献１を参照されたい）。
特開２００１−２４７０５８号公報 On the other hand, the floor panel of the vehicle body is provided with a strength member (cross member) extending in the vehicle body width direction for the purpose of suppressing torsion and vibration of the vehicle body and protecting the passenger compartment from the impact at the time of a side collision (patent) See reference 1).
Japanese Patent Laid-Open No. 2001-247058

しかるに、フロアパネルの所要の剛性を確保するためにクロスメンバを設ける場合、クロスメンバの位置を優先すると、燃料タンクなどの床下設置機器に対する点検口の位置に制約が及び、燃料タンクの形状や付属機器の位置がクロスメンバの位置に制約される。この反対に、点検口の位置を優先すると、クロスメンバの位置が制限され、高効率な強度増強が困難となる。即ち、点検口の適正配置による床下設置機器の保守整備性の確保と、クロスメンバの適正配置による車体剛性の確保とを両立することは困難であった。   However, when a cross member is provided to ensure the required rigidity of the floor panel, priority is given to the position of the cross member, which restricts the position of the inspection port with respect to equipment installed under the floor such as a fuel tank, and the shape and attachment of the fuel tank. The position of the device is constrained by the position of the cross member. On the other hand, if priority is given to the position of the inspection port, the position of the cross member is limited, and it is difficult to increase the strength with high efficiency. That is, it has been difficult to ensure both maintainability of the equipment installed under the floor by proper arrangement of the inspection openings and securing of vehicle body rigidity by proper arrangement of the cross members.

本発明は、このような従来技術の課題を解決すべく案出されたものであり、その主な目的は、例えば燃料タンク等、床下に設置された付属機器の保守整備性の確保と車体剛性の確保とを高次元に両立し得る車体のフロアパネルを提供することにある。   The present invention has been devised to solve such problems of the prior art, and its main purpose is to ensure the maintainability of ancillary equipment installed under the floor such as a fuel tank and the rigidity of the vehicle body. An object of the present invention is to provide a vehicle body floor panel capable of ensuring a high level of compatibility.

このような目的を達成するために本発明は、床下に設置された付属機器にアクセスするために、反復着脱自在にボルトを用いて固定される蓋によって塞がれる点検口４を備える車体のフロアパネル（リアフロアパネル１）において、車体の幅方向に延在するクロスメンバを、前記点検口の左右両脇から車体の外側方へ向けて延設された一対のサイドクロスメンバ６・７と、前記点検口の上方を横切るセンタクロスメンバ８とに分断し、前記各サイドクロスメンバおよび前記センタクロスメンバは、断面形状が台形をなし、前記各サイドクロスメンバは、下端縁をフロアパネル本体上に結合することによって閉断面を形成し、かつその両端部を閉じるようにし、前記センタクロスメンバは、開断面構造をなし、その両端部が、前記各サイドクロスメンバの閉じられた前記両端部の内側端の上面に重ね合わされた状態で、当該両端部の内側端に対してボルトにて反復着脱可能に結合されていることを特徴とするものとした。 In order to achieve such an object, the present invention provides a floor of a vehicle body having an inspection port 4 that is closed by a cover that is removably attached to and bolted in order to access an accessory installed under the floor. In the panel (rear floor panel 1), a pair of side cross members 6 and 7 extending in the width direction of the vehicle body from the left and right sides of the inspection port toward the outside of the vehicle body, The side cross member and the center cross member are divided into trapezoidal cross sections, and each side cross member is coupled with a lower end edge on the floor panel body. to form a closed cross section by, and to close the opposite ends thereof, the center cross member, without the opening cross section structure, both end portions, each Saidokuro In a state of being overlaid on the upper surface of the inner end of said end portion which is closed with a member, and it shall be characterized in that it is repeated detachably coupled by bolts to the inner end of the end portions.

このような本発明によれば、点検口の上方を横切る位置にクロスメンバを架設することができるので、フロアパネルの側面衝突時の変形モードを配慮した適切な位置にクロスメンバを設けることができる上、床下に設置された付属機器を点検する際には、クロスメンバにおける点検口の上方を横切る部分を取り外すことができるので、点検作業に支障をきたさずに済む。従って、フロアパネル並びに床下設置機器の設計の自由度を高める上に大きな効果が得られる。   According to the present invention as described above, since the cross member can be installed at a position crossing the inspection port, the cross member can be provided at an appropriate position in consideration of the deformation mode at the time of a side collision of the floor panel. When inspecting the accessory device installed above and below the floor, the cross member can be removed from the portion of the cross member that crosses the inspection port, so that the inspection work is not hindered. Therefore, a great effect can be obtained in increasing the degree of freedom in designing the floor panel and the equipment installed under the floor.

以下に添付の図面を参照して本発明について詳細に説明する。   Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

図１は、本発明が適用されたリアフロアパネル１の一例であり、車室後部のリアシート取付部２から、トランクルームのスペアタイヤ格納部３へかけての部分に適用したものを例示している。   FIG. 1 is an example of a rear floor panel 1 to which the present invention is applied, and illustrates an example applied to a portion extending from a rear seat mounting portion 2 at the rear of a vehicle compartment to a spare tire storage portion 3 of a trunk room.

このリアフロアパネル１は、鋼板のプレス成形で形成されており、図には一部のみを示したが、車幅方向のビード並びに前後方向のビードを始めとする凹凸を形成した立体的構成とすることにより、所要の剛性の確保が図られている。   The rear floor panel 1 is formed by press forming of a steel plate, and only a part of the rear floor panel 1 is shown in the figure. However, the rear floor panel 1 has a three-dimensional configuration in which irregularities such as a bead in the vehicle width direction and a bead in the front-rear direction are formed. Thus, the required rigidity is ensured.

リアフロアパネル１の上面視の略中心位置には、図２に併せて示したように、床下に設置される燃料タンクの付属機器取付部（図示せず）にアクセスするための点検口４が開設されている。この点検口４は、反復着脱自在なように、ボルトＢ１を用いて固定される蓋５で通常は塞がれている。   As shown in FIG. 2, an inspection port 4 for accessing a fuel tank attachment device (not shown) installed under the floor is opened at a substantially central position in the top view of the rear floor panel 1. Has been. The inspection port 4 is normally closed with a lid 5 fixed with bolts B1 so that it can be repeatedly attached and detached.

側方衝突時の車体変形を抑制するなどの目的のために、リアフロアパネル１の上面の適所には、クロスメンバが車体幅方向に延設されている。このクロスメンバは、点検口４の左右両脇から車体の外側方へ向けて延設された一対のサイドクロスメンバ６・７と、点検口４の上方を横切るセンタクロスメンバ８とからなり、左右に分割された両サイドクロスメンバ６・７の内側端とセンタクロスメンバ８の両端とがボルトＢ２にて結合されている。これにより、センタクロスメンバ８は反復着脱可能に構成されている。   For the purpose of suppressing the deformation of the vehicle body at the time of a side collision, a cross member extends in the vehicle body width direction at an appropriate position on the upper surface of the rear floor panel 1. The cross member includes a pair of side cross members 6 and 7 extending from the left and right sides of the inspection port 4 toward the outside of the vehicle body, and a center cross member 8 crossing the upper side of the inspection port 4. The inner ends of the side cross members 6 and 7 divided into two and the both ends of the center cross member 8 are connected by bolts B2. Thereby, the center cross member 8 is comprised so that repetition attachment or detachment is possible.

各クロスメンバ６〜８は、断面形状が台形をなし、左右のサイドクロスメンバ６・７はその両端部が閉じられており、下端縁に設けられたフランジ９をリアフロアパネル１上にスポット溶接などで結合することによって閉断面を形成している。また左右のサイドクロスメンバ６・７のリアフロアパネル１に対する付け根の部分には、丸棒材から曲成したチャイルドシート用アンカーロッド１０が結合されている。   Each of the cross members 6 to 8 has a trapezoidal cross section, and the left and right side cross members 6 and 7 are closed at both ends, and a flange 9 provided at the lower edge is spot welded on the rear floor panel 1 or the like. The closed cross section is formed by joining together. A child seat anchor rod 10 bent from a round bar is coupled to the base of the left and right side cross members 6 and 7 with respect to the rear floor panel 1.

センタクロスメンバ８は、開断面構造をなし、左右のサイドクロスメンバ６・７の内側端の上面にその両端部を重ね合わせ、且つチャイルドシート用アンカーロッド１０の結合部にその一部を重ねてボルト止めされている。これにより、チャイルドシート用アンカーロッド１０の結合強度の増強にも貢献している。   The center cross member 8 has an open cross-sectional structure, and its both end portions are overlapped with the upper surfaces of the inner ends of the left and right side cross members 6 and 7, and a part of the center cross member 8 is overlapped with the joint portion of the child seat anchor rod 10 It has been stopped. Thereby, it has contributed also to the increase in the joint strength of the anchor rod 10 for child seats.

このように、本発明の車体フロアパネルの構成によれば、点検口４の上方を横切る位置に着脱自在なセンタクロスメンバ８を架設するものとしたので、床下に設置された付属機器を点検する際にはセンタクロスメンバ８を取り外せば良いので、リアフロアパネル１の剛性を確保した上で、点検口４からの床下設置機器へのアクセス性を確保し得る。従って、点検口４の位置の設定自由度とリアフロアパネル１の剛性確保とを高次元に両立することができる。   As described above, according to the configuration of the vehicle body floor panel of the present invention, the detachable center cross member 8 is installed at a position crossing the upper side of the inspection port 4, so that the accessory device installed under the floor is inspected. At this time, since the center cross member 8 may be removed, the rigidity of the rear floor panel 1 can be secured, and the accessibility from the inspection port 4 to the equipment installed under the floor can be secured. Therefore, it is possible to achieve both a high degree of freedom in setting the position of the inspection port 4 and ensuring the rigidity of the rear floor panel 1.
