Description

【０００１】
【発明の属する技術分野】
本発明は、車両のフロア構造に係り、詳しくは、フロアパネルに車両機器の点検用の開口を有する車両のフロア構造に関する。
【０００２】
【関連する背景技術】
小型トラック等の車両では、乗員室の床下にエンジン等の車両機器が配設されており、この車両機器の点検整備をするため、図４に示すように、床部材であるフロアパネル１には点検整備用の開口（インスペクションホール）２が設けられている。そして、当該開口を塞ぐようにしてカバー１０が載置されている。
【０００３】
ところで、この開口は通常は運転席及び助手席の各シート４、６の下に位置しており、カバー１０を外すためにはこれらのシート４、６を外さなければならない。
しかしながら、同図に示すように、運転席のシート４のシートクッション下部には運転姿勢を良好な状態に調節するためにシートスライド装置５が設けられており、当該シートスライド装置５はフロアパネル１またはカバー１０にボルト等の締結具で固定されていることから、運転席のシート４については当該締結具を外さなければカバー１０を外すことができない。
【０００４】
一方、助手席のシート６については、運転席ほど運転姿勢を気にする必要がないため、シートスライド装置は特に必要とされず、例えばシートクッション後部にヒンジを設けてこれをフロアパネル１に固定し、シートクッションを当該ヒンジ回りに跳ね上げることで容易にカバー１０を取り外すことが可能とされている。
【０００５】
このようなことから、カバー１０を運転席のシート４の下部のカバー部材１２と助手席のシート６の下部のカバー部材１４とに分割するようにし、少なくとも助手席のシート６側のカバー部材１４についてはシートクッションを跳ね上げることで容易に開閉できるようにしている。
また、エンジン等の車両機器は車両幅方向で点検整備範囲が広いために開口２の面積も車両幅方向で大きく、上記分割したカバー部材１２、１４の分割位置には当該開口部を補強するようカバーの一部としてフレーム部材１６が車両前後方向に渡されている。
【０００６】
【発明が解決しようとする課題】
上記のようにフレーム部材１６を開口２の前後に渡すようにした場合、フレーム部材１６はフロアパネル１を補強し且つカバー部材１２、１４を支持する役割を果たすものであるため、図５に図４中のＡ−Ａ線に沿う断面を示すが、このように先ずフレーム部材１６をフロアパネル１と一体化するよう取付け、次に当該フレーム部材１６の上に運転席のシート４側のカバー部材１２を重ね、最上に助手席のシート６側のカバー部材１４を載せるようにしている。
【０００７】
ところが、フレーム部材１６と各カバー部材１２、１４とをこのような板組みにすると、助手席のシート６側のカバー部材１４の範囲よりも少しだけ運転席寄りのフレーム部材１６の範囲について車両機器を点検整備したいような場合、運転席のシート４側のカバー部材１２を外さなければフレーム部材１６を外すことができず、上述したように運転席のシート４側のカバー部材１２を外すためには運転席のシート４を外さなければならず、作業に手間が掛かり点検整備性が悪いという問題がある。
【０００８】
本発明はこのような問題点を解決するためになされたもので、その目的とするところは、乗員室のフロアパネルに車両機器の点検整備用の開口を有する車両のフロア構造において、点検整備性の向上を図ったフロア構造を提供することにある。
【０００９】
【課題を解決するための手段】
上記した目的を達成するために、請求項１の発明では、車両の乗員室の床部を形成するフロアパネルに車両機器の点検整備用の開口を設けたフロア構造において、前記開口を閉塞する蓋部材は、フロアパネルにボルトで固定されるとともに乗員用シートが載置されるサイドパネルと、フロアパネルにヒンジで開閉自在に取り付けられるインスペクションカバーと、該サイドパネル及び該インスペクションカバーの間に位置づけられ車両前後方向に架橋されフロアパネルにボルトで固定されると共に、サイドブレーキが装着されて開口を補強する小部品のフレーム部材とを含む三以上の複数に分割されて構成され、該分割された蓋部材を車両幅方向で前記サイドパネル側からインスペクションカバー側へ順次重ね合わせるとともに、フレーム部材とフロアパネルとの固定位置間の前記開口にてフレーム部材がサイドパネルのみにボルトで接合されることを特徴としている。
【００１０】
従って、逆に言えば、三以上に分割された蓋部材を車両機器の点検整備したい範囲に応じて反対側から順次取り外すことが可能とされ、開口面積を一方から他方に向けて連続的に広げることが可能である。
例えば、上記のように蓋部材（カバー）を運転席のシート側のカバー部材と助手席のシート側のカバー部材とフレーム部材からなる三部品に分割した場合には、運転席のシート側のカバー部材から順次重ね合わせることにより、逆に助手席のシート側のカバー部材から順にフレーム部材、運転席のシート側のようにカバー部材を順次開けるようにでき、これにより、助手席のシート側のカバー部材の範囲よりも少しだけ運転席寄りのフレーム部材の範囲について車両機器を点検整備したいような場合において、先ず助手席のシート側のカバー部材を開け、次に運転席のシート側のカバー部材を開けることなくフレーム部材を開けるようにして必要な部材のみ開けて開口面積を広げるようにでき、作業が短時間で完了することになり、点検整備性が向上する。
また、運転席のシート側のカバー部材はフロアパネルにボルトで接合されるとともに、フレーム部材は運転席のシート側のカバー部材にボルトで接合される。これにより、開口が補強されてカバー部材の陥没が防止されるとともに、フロアパネルの強度が大幅に増大する。すなわち、カバー部材上の運転席の座席やドライバーの重量がボルトを介してフレーム部材にも分散されることによって、カバー部材の陥没が防止される。
しかも、フレーム部材は小部品であるため、外したフレーム部材は運転席のシート上に仮置きすることができ、フレーム部材が作業の障害となることなく更に車両機器の点検整備性を向上できる。
【００１１】
【発明の実施の形態】
以下、本発明の実施形態を添付図面に基づき説明する。
図１を参照すると、本発明に係る小型トラック等の乗員室のフロア構造が斜視図で示されており、図２を参照すると、図１中のＢ−Ｂ線に沿うフロア構造の断面図が示されており、以下、これらの図に基づき本発明に係る車両のフロア構造について説明する。なお、図１及び図２中、上述した図４及び図５と同一の部材または部位については同一の符号をそのまま用いる。
【００１２】
上述したように、小型トラック等の車両では、エンジン等の車両機器の点検整備をするため、フロアパネル１には点検整備用のインスペクションホール（開口）２が穿設されている。そして、当該インスペクションホール２を塞ぐようにしてカバー２０が載置されている。
そして、カバー２０は、上述したように、運転席のシート４のシートスライド装置５が固定される等の理由から、運転席のシート４の下部のカバー部材２２と助手席のシート６の下部のカバー部材２４とに分割されている。
【００１３】
カバー部材２２はボルト２８でフロアパネル１に固定されており、一方、カバー部材２４は、車両前後方向後ろ側に設けられた一対のヒンジ１５、１５を介してフロアパネル１に連結されている。これにより、カバー部材２４は当該ヒンジ１５、１５回りに開閉自在である。
詳しくは、助手席のシート６のシートクッション６ａとシートバック６ｂとはフロアパネル１に固定されたヒンジ（図示せず）を介して連結されており、つまりシートクッション６ａはヒンジ回りに回動自在であり、当該シートクッション６ａをヒンジ回りに跳ね上げることでカバー部材２４を開閉することが可能である。即ち、カバー部材２４は助手席のシート６のシートクッション６ａを跳ね上げることで容易にして開閉可能である。なお、このようなことから、固定式である運転席のシート４側のカバー部材２２についてはサイドパネルと呼び、助手席のシート６側の容易に開閉可能なカバー部材２４を一般的にインスペクションカバーと呼ぶこともある。
【００１４】
また、上述したように、エンジン等の車両機器は車両幅方向で点検整備範囲が広いためにインスペクションホール２の開口寸法も車両幅方向で大きく（例えば、車両幅方向で９００mm）、故に上記分割したカバー部材２２とカバー部材２４の分割位置には当該開口部を補強するようにフレーム部材（シートアンダフレーム）２６がカバー２０の一部として車両前後方向に渡されている。
【００１５】
図２に示すように、当該フレーム部材２６は、上記従来の場合と異なり、カバー部材２２を先にフロアパネル１に固定した後、当該カバー部材２２に重ね合わせるようにしてフロアパネル１にボルト３０で固定されている。また、カバー部材２２に設けられたボルト貫通孔２２ａの周縁には背面側にウェルドナット２９が溶接されており、一方フレーム部材２６にはボルト貫通孔２２ａに対応してボルト貫通孔２６ａが設けられており、フレーム部材２６はボルト２８でカバー部材２２にも接合されている。
【００１６】
このようにフレーム部材２６がカバー部材２２にボルト２８で接合されていると、カバー部材２２はフレーム部材２６に支持されることになり、カバー部材２２の陥没等が防止される。
そして、フレーム部材２６がフロアパネル１及びカバー部材２２と接合された状態でカバー部材２４が閉じられることによって、カバー部材２４がフレーム部材２６に重ね合わされている。
【００１７】
つまり、図２に示すように、カバー部材２２、フレーム部材２６及びカバー部材２４は、この順で運転席のシート４側（片側）から順次重ね合わせるように配設されている。
このように、カバー部材２２、フレーム部材２６及びカバー部材２４が運転席のシート４側（片側）から順次重ね合わせるように配設されていると、逆に言えば、カバー２０を助手席のシート６側のカバー部材２４から順に開けることができることになる。つまり、助手席のシート６側のカバー部材２４を先ず開き、次にフレーム部材２６を取り外し、最後にカバー部材２２を取り外すという作業が可能となる。
【００１８】
即ち、図３を参照すると、エンジン４０等の車両機器を点検整備すべく、先ず助手席のシート６のシートクッション６ａを跳ね上げてカバー部材２４を開き、さらにフレーム部材２６を取り外した状態の図が示されているが、カバー部材２２、フレーム部材２６及びカバー部材２４を運転席のシート４側から順次重ね合わせるように配設することで、このようにカバー部材２２を外すことなくフレーム部材２６を取り外すことが可能となる。
【００１９】
つまり、カバー部材２２を外そうとすると運転席のシート４を外さなければならないのであるが、このようにカバー部材２２、フレーム部材２６及びカバー部材２４を運転席のシート４側から順次重ね合わせるような板組とすることで、助手席のシート６側のカバー部材２４の範囲よりも少しだけ運転席寄りのフレーム部材２６の範囲で車両機器を点検整備したいような場合において、運転席のシート４及びカバー部材２２を一切外さずにフレーム部材２６を外すようにできる。
【００２０】
これにより、通常の点検整備時には、シート４及びカバー部材２２をそのままにし、煩雑な作業をすることなく必要な部材だけを開けて広範囲に亘り点検整備作業を行うことができ、短時間で作業を完了でき、点検整備性が良い。
なお、フレーム部材２６の板厚（例えば、ｔ＝１．６mm）はフロアパネル１やカバー部材２２、２４の板厚（例えば、ｔ＝０．９mm）よりも厚く十分な強度を有しているので、このような板組であってもフレーム部材２６はカバー部材２２、２４を確実に支持できる。
【００２１】
また、図３に示すように、実際にはフレーム部材２６にサイドブレーキ５０が取り付けられており、フレーム部材２６を外す際、当該サイドブレーキ５０後部から延びるブレーキケーブルでフレーム部材２６を仮置きする範囲が制限される。しかしながら、フレーム部材２６は小部品であるので、例えば運転席のシート４上に仮置きすることができ、このことが点検整備作業の障害となることはない。
【００２２】
ところで、上記実施形態では、助手席のシート６側のカバー部材２４を跳ね上げ式としたが、ヒンジ１５を設けずにカバー部材２４をボルトでフロアパネル１に固定するようにしてもよく、また、カバー部材２４をヒンジ１５で跳ね上げ式とするとともに併せてボルトでフロアパネル１に固定するようにしてもよい。
また、上記実施形態では、カバー２０がカバー部材２２、フレーム部材２６、カバー部材２４の三部品に分割されている場合を例に説明したが、カバー２０は三部品のみならず四部品以上に分割されていてもよい。
【００２３】
また、上記実施形態では、ボルト２８によるカバー部材２２とフレーム部材２６との接合を一カ所のみで行っているが、２カ所以上とするのが好ましい。
【００２４】
【発明の効果】
以上詳細に説明したように、本発明の請求項１の車両のフロア構造によれば、三以上に分割された開口の蓋部材を車両機器の点検整備したい範囲に応じて順次取り外すようにでき、開口面積を一方から他方に向けて連続的に広げることができる。
【００２５】
従って、例えば、蓋部材（カバー）を運転席のシート側のカバー部材と助手席のシート側のカバー部材とフレーム部材からなる三部品に分割した場合には、運転席のシート側のカバー部材から順次重ね合わせるようにすることで、逆に助手席のシート側のカバー部材から順にフレーム部材、運転席のシート側のようにカバーを順次開けるようにでき、これにより、助手席のシート側のカバー部材の範囲よりも少しだけ運転席寄りのフレーム部材の範囲について車両機器を点検整備したいような場合において、先ず助手席のシート側のカバー部材を開け、次に運転席のシート側のカバー部材を開けることなくフレーム部材を開けるようにして必要な部材のみ開けて開口面積を広げるようにでき、作業を短時間で完了させて点検整備性を向上させることができる。
また、運転席のシート側のカバー部材はフロアパネルにボルトで接合されるとともに、フレーム部材は運転席のシート側のカバー部材にボルトで接合される。これにより、開口が補強されてカバー部材の陥没が防止されるとともに、フロアパネルの強度が大幅に増大する。すなわち、カバー部材上の運転席の座席やドライバーの重量がボルトを介してフレーム部材にも分散されることによって、カバー部材の陥没が防止される。
しかも、フレーム部材は小部品であるため、外したフレーム部材は運転席のシート上に仮置きすることができ、フレーム部材が作業の障害となることなく更に車両機器の点検整備性を向上できる。

BACKGROUND OF THE INVENTION
The present invention relates to a vehicle floor structure, and more particularly to a vehicle floor structure having an opening for inspection of vehicle equipment in a floor panel.
[0002]
[Related background]
In a vehicle such as a light truck, vehicle equipment such as an engine is disposed under the floor of the passenger compartment. In order to inspect and maintain the vehicle equipment, as shown in FIG. An opening (inspection hole) 2 for inspection and maintenance is provided. The cover 10 is placed so as to close the opening.
[0003]
By the way, this opening is normally located under the respective seats 4 and 6 of the driver seat and the passenger seat, and in order to remove the cover 10, these seats 4 and 6 must be removed.
However, as shown in the figure, a seat slide device 5 is provided below the seat cushion of the driver's seat 4 in order to adjust the driving posture to a good state. The seat slide device 5 is provided on the floor panel 1. Or since it is being fixed to the cover 10 with fasteners, such as a volt | bolt, about the seat 4 of a driver's seat, the cover 10 cannot be removed unless the said fastener is removed.
[0004]
On the other hand, the passenger seat 6 does not need to care about the driving posture as much as the driver's seat, so a seat slide device is not particularly required. For example, a hinge is provided at the rear of the seat cushion to fix it to the floor panel 1. The cover 10 can be easily removed by flipping up the seat cushion around the hinge.
[0005]
For this reason, the cover 10 is divided into a lower cover member 12 of the driver's seat 4 and a lower cover member 14 of the passenger seat 6, and at least the cover member 14 on the passenger seat 6 side. With regard to, it is possible to easily open and close by flipping up the seat cushion.
Further, since the vehicle equipment such as the engine has a wide inspection and maintenance range in the vehicle width direction, the area of the opening 2 is also large in the vehicle width direction, and the opening is reinforced at the divided positions of the divided cover members 12 and 14. A frame member 16 is passed in the vehicle front-rear direction as a part of the cover.
[0006]
[Problems to be solved by the invention]
When the frame member 16 is passed before and after the opening 2 as described above, the frame member 16 serves to reinforce the floor panel 1 and support the cover members 12 and 14. 4 shows a cross section taken along the line AA in FIG. 4, thus first attaching the frame member 16 so as to be integrated with the floor panel 1, and then covering the frame member 16 on the seat 4 side of the driver's seat. 12, the cover member 14 on the passenger seat 6 side is placed on top.
[0007]
However, when the frame member 16 and the cover members 12 and 14 are made into such a plate assembly, the vehicle equipment in the range of the frame member 16 slightly closer to the driver's seat than the range of the cover member 14 on the passenger seat 6 side. In order to remove the cover member 12 on the driver's seat 4 side as described above, the frame member 16 cannot be removed unless the cover member 12 on the driver's seat 4 side is removed. Has to remove the seat 4 of the driver's seat, and there is a problem that the work is troublesome and the inspection and maintenance are poor.
[0008]
SUMMARY OF THE INVENTION The present invention has been made to solve such problems, and the object of the present invention is to provide inspection and maintainability in a vehicle floor structure having an opening for inspection and maintenance of vehicle equipment in a floor panel of a passenger compartment. The object is to provide a floor structure that is improved.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, in a floor structure in which an opening for inspection and maintenance of vehicle equipment is provided in a floor panel forming a floor portion of a passenger compartment of a vehicle, a lid for closing the opening. The member is positioned between the side panel that is fixed to the floor panel with bolts and on which the occupant's seat is placed, the inspection cover that is attached to the floor panel by a hinge so as to be opened and closed, and the side panel and the inspection cover. The lid is divided into three or more divided parts including a frame member that is bridged in the vehicle longitudinal direction and fixed to the floor panel with bolts and a side brake is attached to reinforce the opening. causes sequentially superimposed to inspection cover side from the member in the vehicle width direction the side panel side, the frame portion Frame member is characterized by being bolted only to the side panels in the opening between the fixed position of the floor panel and.
[0010]
Therefore, conversely, the lid member divided into three or more can be sequentially removed from the opposite side according to the range in which inspection and maintenance of the vehicle equipment is desired, and the opening area is continuously expanded from one to the other. It is possible.
For example, when the lid member (cover) is divided into three parts consisting of a cover member on the seat side of the driver seat, a cover member on the seat side of the passenger seat, and a frame member as described above, the cover on the seat side of the driver seat By sequentially overlapping the members, the cover members can be opened sequentially from the cover member on the passenger seat side to the frame member, the driver seat side, and so on. When you want to inspect and maintain the vehicle equipment for the range of the frame member that is slightly closer to the driver's seat than the range of the member, first open the cover member on the passenger's seat side, and then open the cover member on the seat side of the driver's seat By opening the frame member without opening it, only the necessary members can be opened to widen the opening area, and the work will be completed in a short time, and inspection and maintenance will be completed. There is improved.
The cover member on the seat side of the driver's seat is joined to the floor panel with bolts, and the frame member is joined to the cover member on the seat side of the driver's seat with bolts. As a result, the opening is reinforced to prevent the cover member from being depressed, and the strength of the floor panel is greatly increased. That is, the weight of the driver's seat on the cover member and the driver is also distributed to the frame member via the bolts, thereby preventing the cover member from collapsing.
Moreover, since the frame member is a small part, the removed frame member can be temporarily placed on the seat of the driver's seat, and the inspection and maintainability of the vehicle equipment can be further improved without the frame member becoming an obstacle to work.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
Referring to FIG. 1, a floor structure of a passenger compartment such as a small truck according to the present invention is shown in a perspective view. Referring to FIG. 2, a sectional view of the floor structure taken along line BB in FIG. Hereinafter, the vehicle floor structure according to the present invention will be described with reference to these drawings. 1 and 2, the same reference numerals are used as they are for the same members or parts as those in FIGS. 4 and 5 described above.
[0012]
As described above, in a vehicle such as a light truck, an inspection hole (opening) 2 for inspection and maintenance is formed in the floor panel 1 in order to inspect and maintain vehicle equipment such as an engine. A cover 20 is placed so as to close the inspection hole 2.
As described above, the cover 20 has a cover member 22 below the driver's seat 4 and a lower seat 6 at the passenger's seat 6 because the seat slide device 5 for the driver's seat 4 is fixed. The cover member 24 is divided.
[0013]
The cover member 22 is fixed to the floor panel 1 with bolts 28 , while the cover member 24 is connected to the floor panel 1 via a pair of hinges 15 and 15 provided on the rear side in the vehicle front-rear direction. Thereby, the cover member 24 can be opened and closed around the hinges 15 and 15.
Specifically, the seat cushion 6a and the seat back 6b of the passenger seat 6 are connected via a hinge (not shown) fixed to the floor panel 1, that is, the seat cushion 6a is rotatable around the hinge. The cover member 24 can be opened and closed by flipping up the seat cushion 6a around the hinge. That is, the cover member 24 can be easily opened and closed by flipping up the seat cushion 6 a of the passenger seat 6. For this reason, the cover member 22 on the driver's seat 4 side that is fixed is called a side panel, and the cover member 24 that can be easily opened and closed on the passenger seat 6 side is generally an inspection cover. Sometimes called.
[0014]
Further, as described above, since the vehicle equipment such as the engine has a wide inspection and maintenance range in the vehicle width direction, the opening size of the inspection hole 2 is also large in the vehicle width direction (for example, 900 mm in the vehicle width direction). A frame member (seat underframe) 26 is provided as a part of the cover 20 in the vehicle front-rear direction so as to reinforce the opening at the divided position of the cover member 22 and the cover member 24.
[0015]
As shown in FIG. 2, unlike the conventional case, the frame member 26 has bolts 30 attached to the floor panel 1 so that the cover member 22 is first fixed to the floor panel 1 and then overlapped with the cover member 22. It is fixed with. In addition, a weld nut 29 is welded to the periphery of the bolt through hole 22a provided in the cover member 22, and a bolt through hole 26a is provided in the frame member 26 corresponding to the bolt through hole 22a. The frame member 26 is also joined to the cover member 22 with bolts 28 .
[0016]
When the frame member 26 is thus joined to the cover member 22 with the bolts 28 , the cover member 22 is supported by the frame member 26, and the cover member 22 is prevented from being depressed.
The cover member 24 is overlaid on the frame member 26 by closing the cover member 24 in a state where the frame member 26 is joined to the floor panel 1 and the cover member 22.
[0017]
That is, as shown in FIG. 2, the cover member 22, the frame member 26, and the cover member 24 are arranged so as to be sequentially overlapped in this order from the seat 4 side (one side) of the driver's seat.
Thus, if the cover member 22, the frame member 26, and the cover member 24 are arranged so as to be sequentially overlapped from the seat 4 side (one side) of the driver's seat, conversely, the cover 20 is seated on the passenger seat. It can be opened sequentially from the cover member 24 on the 6th side. That is, it is possible to perform an operation of first opening the cover member 24 on the passenger seat 6 side, then removing the frame member 26, and finally removing the cover member 22.
[0018]
That is, referring to FIG. 3, in order to inspect and maintain the vehicle equipment such as the engine 40, first, the seat cushion 6a of the passenger seat 6 is flipped up, the cover member 24 is opened, and the frame member 26 is further removed. Although the cover member 22, the frame member 26, and the cover member 24 are disposed so as to be sequentially stacked from the seat 4 side of the driver's seat, the frame member 26 is thus removed without removing the cover member 22. Can be removed.
[0019]
That is, when the cover member 22 is to be removed, the driver's seat 4 must be removed. In this way, the cover member 22, the frame member 26, and the cover member 24 are sequentially stacked from the seat 4 side of the driver's seat. When the vehicle assembly is to be inspected and maintained in the range of the frame member 26 slightly closer to the driver's seat than the range of the cover member 24 on the front passenger seat 6 side, the driver's seat 4 And the frame member 26 can be removed without removing the cover member 22 at all.
[0020]
As a result, during normal inspection and maintenance, the seat 4 and the cover member 22 can be left as they are, and only necessary members can be opened and the inspection and maintenance work can be performed over a wide range without complicated operations. It can be completed and has good serviceability.
The plate thickness of the frame member 26 (for example, t = 1.6 mm) is thicker than the plate thickness of the floor panel 1 and the cover members 22 and 24 (for example, t = 0.9 mm) and has sufficient strength. Therefore, the frame member 26 can reliably support the cover members 22 and 24 even in such a plate assembly.
[0021]
In addition, as shown in FIG. 3, the side brake 50 is actually attached to the frame member 26, and when the frame member 26 is removed, the frame member 26 is temporarily placed with a brake cable extending from the rear portion of the side brake 50. Is limited. However, since the frame member 26 is a small part, it can be temporarily placed on the seat 4 of the driver's seat, for example, and this does not hinder the inspection and maintenance work.
[0022]
In the above embodiment, the cover member 24 on the passenger seat 6 side is a flip-up type, but the cover member 24 may be fixed to the floor panel 1 with bolts without providing the hinge 15, The cover member 24 may be flipped up by the hinge 15 and fixed to the floor panel 1 with bolts.
In the above embodiment, the case where the cover 20 is divided into three parts of the cover member 22, the frame member 26, and the cover member 24 has been described as an example. However, the cover 20 is divided not only into three parts but also into four or more parts. May be.
[0023]
Further, in the above embodiment, the cover member 22 and the frame member 26 are joined by the bolt 28 at only one place, but it is preferable to have two or more places.
[0024]
【The invention's effect】
As described above in detail, according to the vehicle floor structure of claim 1 of the present invention, the lid member of the opening divided into three or more can be sequentially removed according to the range where inspection and maintenance of the vehicle equipment is desired, The opening area can be continuously expanded from one to the other.
[0025]
Therefore, for example, when the lid member (cover) is divided into three parts including a cover member on the seat side of the driver's seat, a cover member on the seat side of the passenger seat, and a frame member, the cover member on the seat side of the driver's seat By sequentially overlapping, it is possible to open the cover sequentially from the cover member on the passenger seat side to the frame member, the driver seat side, and so on. When you want to inspect and maintain the vehicle equipment for the range of the frame member that is slightly closer to the driver's seat than the range of the member, first open the cover member on the passenger's seat side, and then open the cover member on the seat side of the driver's seat By opening the frame member without opening it, only the necessary members can be opened to widen the opening area, and the work can be completed in a short time, improving the serviceability. It is possible.
The cover member on the seat side of the driver's seat is joined to the floor panel with bolts, and the frame member is joined to the cover member on the seat side of the driver's seat with bolts. As a result, the opening is reinforced to prevent the cover member from being depressed, and the strength of the floor panel is greatly increased. That is, the weight of the driver's seat on the cover member and the driver is also distributed to the frame member via the bolts, thereby preventing the cover member from collapsing.
Moreover, since the frame member is a small part, the removed frame member can be temporarily placed on the seat of the driver's seat, and the inspection and maintainability of the vehicle equipment can be further improved without the frame member becoming an obstacle to work.
