Description

【0001】
【発明の属する技術分野】
この発明は、車室後方の床面にスペアタイヤを格納する車両の車体後部フロア構造に関するものである。
【0002】
【従来の技術】
車室後方の床面にスペアタイヤを格納する車両の車体後部フロアとしては、例えば実開平7−35261号公報に示されているものがある。
これは、車体後部フロアに設けられたスペアタイヤパンの前端部を前上がりの傾斜壁とし、この傾斜壁を車外側から補強したことにより、後面衝突時に前方に押し出されたスペアタイヤによる傾斜壁の変形を抑え、スペアタイヤを確実に上方へ跳ね上げるようにしたものである。これにより、スペアタイヤがスペアタイヤパンの前端部周辺を変形させることを防止し、これらの前方に配される燃料タンクへの影響をなくすようにしている。
【0003】
【発明が解決しようとする課題】
しかしながら、このような従来の車体後部フロア構造においては、後面衝突時に跳ね上げられたスペアタイヤがその姿勢のまま前方に押し出されてしまうため、荷室の前部に配置される搭載物を保護する必要がある。そのため、車体重量が増加し、荷室内スペースを狭くするという問題がある。
この発明は上記事情に鑑みてなされたもので、後面衝突時、跳ね上げられたスペアタイヤの動きを制御し、軽量、省スペースで安全性をより一層高める車体後部フロア構造を提供するものである。
【0004】
【課題を解決するための手段】
上記課題の解決手段として、請求項1に記載した発明は、リアフロア(例えば実施の形態におけるリアフロア11)のスペアタイヤパン(例えば実施の形態におけるスペアタイヤパン13)の前端部に傾斜壁(例えば実施の形態における傾斜壁16)を形成し、板状部材(例えば実施の形態における板状部材20)を前記傾斜壁の上部から車体後方へ突出した状態でリアフロアに固定し、前記板状部材のリアフロアへの固定部(例えば実施の形態における接合部21)よりも後方に簡易接合部(例えば実施の形態における簡易接合部28)を設け、前記スペアタイヤパンに水平に収容されたスペアタイヤ(例えば実施の形態におけるスペアタイヤ12)が前方に押し出された際には、該スペアタイヤの前部が前記傾斜壁によって上方に跳ね上げられると共に前記板状部材に干渉し、該板状部材が前記簡易接合部を剥離させると共に上方に折れ曲がって縦壁となることを特徴とする車体後部フロア構造を提供する。
これにより、後面衝突時、板状部材が跳ね上げられるスペアタイヤに干渉して変形し、スペアタイヤの運動エネルギーの吸収を行うと共に、縦壁となってスペアタイヤの跳ね上げ方向を制御することができる。
【0005】
請求項2に記載した発明は、前記板状部材のリアフロアへの固定部(例えば実施の形態における接合部21)よりも、車体後方への突出部(例えば実施の形態における突出部22)を高剛性としたことを特徴とする請求項1に記載の車体後部フロアを提供する。
これにより、固定部と突出部との間に変形応力を集中させ、板状部材の折れ曲がりを所定の位置に発生させることができる。
【0006】
【発明の実施の形態】
以下、この発明の実施の形態を図面と共に説明する。
図1、図2に示す車両1はハイブリット車両であって、この車両1は、エンジンをモータによって駆動補助し、車両減速時にモータを発電機として用いて電力を回収する高圧バッテリ等の高圧電装部品を備えている。これら高圧電装部品は略箱型の高圧電装ボックス2内に収容され、一体のユニットとしてリアシート3の背後に搭載されている。
【0007】
車室4の後方に配置されるリアシート3は、シート本体5が図示しないシートレールを介して車体1aのフロア6に取り付けられ、シートバック7がその上部を車体1aのリアシェルフ8に、下部が車体1aのリアクロスメンバ9に取り付けられている。フロア6は、シート本体5の下方から後方に向かうにつれて上方に変化すると共に、シートバック7の下部近傍に車幅方向で延設されるリアクロスメンバ9を境として荷室10の床面を形成する車体1aのリアフロア11に接続されている。
【0008】
リアフロア11は、その面内方向の略中央であって略方形の範囲が下方に向かって膨出成形され、ここにはスペアタイヤ12を水平に収容可能なスペアタイヤパン13が形成されている。また、スペアタイヤパン13の前方であって、フロア6の上方変化によって形成されるフロア6下の空間には、燃料タンク14が配設されている。リアシート3の背後に搭載される高圧電装ボックス2は、車体1aの左右のホイルハウス15間に配置されており、シートバック7の背面に沿って後方に傾斜した姿勢で適宜個所を車体1aに取り付けられている。
【0009】
スペアタイヤパン13の前端側内壁は、車幅方向と略平行であって前上がりの傾斜壁16として形成されている。なお、17はフロアトリムを示す。
そして、リアフロア11には、傾斜壁16の車幅方向略中央であって、傾斜壁16の上縁部18から後方へ突出するように設けられた板状部材20が配置されている。
【0010】
図3に示すように、板状部材20は、各角部がR面取りされた略方形状の部材であり、その前部がリアフロア11の上面に重合し、複数箇所(この実施形態においては5箇所)を例えばスポット溶接によって車幅方向と略平行に接合され、この部分が接合部(固定部)21として構成されている。また、この板状部材20の後部には、上方に突出する複数のリブ23が車幅方向に等間隔で形成されており、この部分が突起部22として構成されている。したがって、突起部22は、接合部21に対して高剛性とされている。この突起部22は、接合部21から後方に延びてスペアタイヤパン13の傾斜壁16の上縁部18から突出すると共に、その前部がリアフロア11の上面に重合するように設けられている。
【0011】
各リブ23は、板状部材20の後縁部24から前記接合部21の手前まで形成されており、したがって、リブ23の前側の終端部25が板状部材20の接合部21の手前で車幅方向と略平行な直線上に並ぶこととなる。ここで、板状部材20の後縁部24は、傾斜壁16の下縁部19より前方に位置するように設けられている(図1参照)。また、板状部材20は、その突出部22の剛性をリブ23の数を増やすことで高めているため、リブ23の突出高さhが抑えられている。
【0012】
また、板状部材20の接合部21の後方であって、突出部22のリアフロア11との重合部27の両側部には、例えばスポット溶接の電流値を下げる等により、接合部21の溶接に対して比較的接合力の弱い簡易溶接が施された簡易接合部28,28が設けられている。
【0013】
次に、作用について説明する。
後面衝突等により、車両1の後方から大きな衝撃が加わって車体1aの後部が変形した場合、リアフロア11のスペアタイヤパン13に水平に収容されていたスペアタイヤ12は、スペアタイヤパン13の後端側内壁29により前方に押し出されるが、スペアタイヤパン13の前端側の傾斜壁16によって、スペアタイヤ12の前部が上方に跳ね上げられるため、スペアタイヤパン13の前方に配置される燃料タンク14に大きな荷重による変形等が生じることを確実に防止することができる。
【0014】
このとき、上方に跳ね上げられようとするスペアタイヤ12が、傾斜壁16の上縁部18から後方へ突出するように設けられている板状部材20に干渉することにより、板状部材20は接合部21より後方の部位が上方に向かって変形しようとする。板状部材20の後部の突出部22はリブ23により剛性を高められているため、各リブ23の終端部25と接合部21との間に変形応力が集中することとなる。各リブ23の前側の終端部25は車幅方向に平行な直線上に並んでいるため、板状部材20には、接合部21と各リブ23の終縁部25との間に車幅方向に平行な折れ線26が生じることとなる。
【0015】
さらに、スペアタイヤ12との干渉により変形しようとする板状部材20は、突出部22の重合部27の各簡易溶接部28がリアフロア11から剥離して上方に向かって折れ曲がっていく。このとき、スペアタイヤ12の運動エネルギーを、板状部材20が折れ曲がることで吸収していく。折れ曲がった板状部材20は、図4に示すように、複数のリブ23によって補強された縦壁となって跳ね上がったスペアタイヤ12’に対向するような姿勢となり、高圧電装ボックス2への衝接を防止しながら、スペアタイヤ12の前部がリアシェルフ8付近に達するように案内することとなる。
【0016】
上述した実施の形態によれば、後面衝突時、スペアタイヤパン13の前端部に設けられた板状部材20が、跳ね上げられたスペアタイヤ12に干渉して変形すると共に縦壁となることで、スペアタイヤ12がさらに前方に押し出されてシートバック7の背後の高圧電装ボックス2に影響を与えないよう、スペアタイヤ12の跳ね上げ方向を制御することで、車体重量の増加を抑え且つ荷室10のスペースを狭めずに、後面衝突時の安全性をより一層高めることができる。
【0017】
このとき、板状部材20のリブ23の形状やリアフロア11との簡易接合部28の位置等を調整することで、スペアタイヤ12の跳ね上げ方向を任意に設定できると共に、様々な車両においても適用することができる。また、板状部材20の後縁部24は、スペアタイヤパン13の傾斜壁16の下縁部19よりも前方に設けられているため、スペアタイヤパン13の実質開口面積を狭めることはない。さらに、板状部材20のリブ23の突出高さを低く設定したため、リアフロア11の上面への突出量を最小限に抑えることができる点で有利である。
【0018】
なお、この発明は上記実施の形態に限られるものではなく、例えば、板状部材20は、リブ23の有無ではなく、板厚違いや2枚重ね等により接合部21と突出部22とに剛性差を持たせるようにしてもよい。
【0019】
また、図5に示すように、ヒンジ構造を有する板状部材30としてもよい。具体的には、リアフロア11に当接する前側板状部材31の車幅方向に平行な後縁部33に後側板状部材32を上下方向に回動可能に連結して、前側板状部材31の後縁部33に沿う回動部分を前記折れ線26とすることで、板状部材30の折れ線を所望の位置に確実に設けることができ、スペアタイヤ12の跳ね上げ方向をより確実に制御することができる。なお、図5において、図2と同一部分に同一符号を付して説明を省略する。さらに、折れ線部分に車幅方向に平行なリブ等を有する弾性ヒンジ構造として簡略化を図ることも可能である。
【0020】
【発明の効果】
以上説明してきたように、請求項1に記載した発明によれば、後面衝突時、板状部材が跳ね上げられるスペアタイヤに干渉して変形し、スペアタイヤの運動エネルギーの吸収を行うと共に、縦壁となってスペアタイヤの跳ね上げ方向を制御することができるため、特にシートバックの後方に搭載物がある車両の場合、その搭載物部への影響を回避して、後面衝突時の安全性をより一層高める効果がある。なお、板状部材は、スペアタイヤパンの開口を狭めることなく、またリアフロアの上面に沿って設けられているため、荷室の使い勝手を低下させることはない。
【0021】
請求項2に記載した発明によれば、固定部と突出部との間に変形応力を集中させ、板状部材の折れ曲がりを任意に発生させることができるため、スペアタイヤの跳ね上げを制御して後面衝突時の安全性を高めると共に、様々な車両に適用できる効果がある。

[Means for Solving the Problems]
As a means for solving the above problems, the invention described in claim 1 is characterized in that an inclined wall (for example, implementation) is provided at a front end portion of a spare tire pan (for example, spare tire pan 13 in the embodiment) of a rear floor (for example, the rear floor 11 in the embodiment). The plate-like member (for example, plate-like member 20 in the embodiment) is fixed to the rear floor in a state protruding from the upper part of the inclined wall to the rear of the vehicle body, and the rear floor of the plate-like member is formed. A simple joint portion (for example, the simple joint portion 28 in the embodiment) is provided behind the fixing portion (for example, the joint portion 21 in the embodiment), and the spare tire (for example, the embodiment) horizontally accommodated in the spare tire pan is provided. When the spare tire 12) is pushed forward, the front part of the spare tire jumps upward by the inclined wall. Interfere with the plate-like member with is to provide a rear vehicle body floor structure characterized by comprising a vertical wall bent upward with the plate-like member to separate the simple joint.
Thereby, at the time of a rear collision, the plate-like member interferes with the spare tire to be flipped up and deforms, absorbs the kinetic energy of the spare tire, and becomes a vertical wall to control the jumping direction of the spare tire. it can.
[0005]
According to the second aspect of the present invention, the protruding portion (for example, the protruding portion 22 in the embodiment) toward the rear of the vehicle body is higher than the fixing portion (for example, the bonding portion 21 in the embodiment) of the plate-like member to the rear floor. The vehicle body rear floor according to claim 1, wherein the vehicle body rear floor is provided.
Thereby, deformation stress can be concentrated between a fixed part and a projection part, and bending of a plate-shaped member can be generated in a predetermined position.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
The vehicle 1 shown in FIGS. 1 and 2 is a hybrid vehicle. The vehicle 1 is a high-voltage battery component such as a high-voltage battery that assists driving of the engine by a motor and collects electric power by using the motor as a generator when the vehicle decelerates. It has. These high-voltage components are housed in a substantially box-shaped high-voltage device box 2 and are mounted behind the rear seat 3 as an integral unit.
[0007]
The rear seat 3 disposed behind the passenger compartment 4 has a seat body 5 attached to a floor 6 of a vehicle body 1a via a seat rail (not shown), a seat back 7 having an upper portion thereof as a rear shelf 8 of the vehicle body 1a and a lower portion thereof. It is attached to the rear cross member 9 of the vehicle body 1a. The floor 6 changes upward as it goes rearward from the lower side of the seat body 5 and forms the floor surface of the luggage compartment 10 with a rear cross member 9 extending in the vehicle width direction in the vicinity of the lower portion of the seat back 7 as a boundary. Connected to the rear floor 11 of the vehicle body 1a.
[0008]
The rear floor 11 is substantially centered in the in-plane direction, and has a substantially rectangular range bulging downward, and a spare tire pan 13 that can accommodate the spare tire 12 horizontally is formed here. A fuel tank 14 is disposed in a space in front of the spare tire pan 13 and below the floor 6 formed by the upward change of the floor 6. The high-voltage equipment box 2 mounted behind the rear seat 3 is disposed between the left and right wheel houses 15 of the vehicle body 1a, and is appropriately attached to the vehicle body 1a in a posture inclined rearward along the back surface of the seat back 7. It has been.
[0009]
The front end side inner wall of the spare tire pan 13 is formed as an inclined wall 16 that is substantially parallel to the vehicle width direction and that rises forward. Reference numeral 17 denotes a floor trim.
A plate-like member 20 is disposed on the rear floor 11 so as to protrude rearward from the upper edge portion 18 of the inclined wall 16 at the approximate center of the inclined wall 16 in the vehicle width direction.
[0010]
As shown in FIG. 3, the plate-like member 20 is a substantially square-shaped member whose corners are chamfered, and the front portion thereof is superposed on the upper surface of the rear floor 11 to form a plurality of locations (5 in this embodiment). The portion is joined substantially parallel to the vehicle width direction by spot welding, for example, and this portion is configured as a joint portion (fixed portion) 21. Further, a plurality of ribs 23 projecting upward are formed at equal intervals in the vehicle width direction at the rear portion of the plate-like member 20, and this portion is configured as a protrusion 22. Therefore, the protrusion 22 is highly rigid with respect to the joint 21. The protrusion 22 extends rearward from the joint 21 and protrudes from the upper edge 18 of the inclined wall 16 of the spare tire pan 13, and is provided so that the front thereof overlaps the upper surface of the rear floor 11.
[0011]
Each rib 23 is formed from the rear edge portion 24 of the plate-like member 20 to the front side of the joint portion 21, and therefore the front end portion 25 of the rib 23 is positioned in front of the joint portion 21 of the plate-like member 20. They are arranged on a straight line substantially parallel to the width direction. Here, the rear edge portion 24 of the plate-like member 20 is provided so as to be positioned in front of the lower edge portion 19 of the inclined wall 16 (see FIG. 1). Further, since the plate-like member 20 increases the rigidity of the protruding portion 22 by increasing the number of ribs 23, the protruding height h of the rib 23 is suppressed.
[0012]
Further, on the both sides of the overlapping portion 27 with the rear floor 11 of the protruding portion 22 behind the joint portion 21 of the plate-like member 20, for example, by reducing the current value of spot welding, etc. On the other hand, simple joint portions 28 and 28 are provided which are subjected to simple welding with relatively weak joining force.
[0013]
Next, the operation will be described.
When the rear part of the vehicle body 1 a is deformed due to a large impact from the rear of the vehicle 1 due to a rear collision or the like, the spare tire 12 accommodated horizontally in the spare tire pan 13 on the rear floor 11 Although it is pushed forward by the side inner wall 29, the front portion of the spare tire 12 is flipped upward by the inclined wall 16 on the front end side of the spare tire pan 13, so that the fuel tank 14 disposed in front of the spare tire pan 13 It is possible to reliably prevent deformation due to a large load.
[0014]
At this time, the spare tire 12 that is about to be lifted upward interferes with the plate-like member 20 provided so as to protrude rearward from the upper edge portion 18 of the inclined wall 16, whereby the plate-like member 20 is A site behind the joint 21 tends to deform upward. Since the protruding portion 22 at the rear portion of the plate-like member 20 is enhanced in rigidity by the rib 23, deformation stress is concentrated between the terminal end portion 25 of each rib 23 and the joint portion 21. Since the front end portions 25 of the ribs 23 are arranged on a straight line parallel to the vehicle width direction, the plate-like member 20 has a width direction between the joint portion 21 and the end edge portion 25 of each rib 23. A polygonal line 26 is generated parallel to the line.
[0015]
Further, in the plate-like member 20 to be deformed due to the interference with the spare tire 12, each simple welded portion 28 of the overlapping portion 27 of the protruding portion 22 is peeled off from the rear floor 11 and bent upward. At this time, the kinetic energy of the spare tire 12 is absorbed by the bending of the plate member 20. As shown in FIG. 4, the bent plate-like member 20 is in a posture to face the spare tire 12 ′ which is a vertical wall reinforced by a plurality of ribs 23 and jumps up, and comes into contact with the high piezoelectric equipment box 2. Thus, the front part of the spare tire 12 is guided so as to reach the vicinity of the rear shelf 8.
[0016]
According to the above-described embodiment, the plate-like member 20 provided at the front end portion of the spare tire pan 13 is deformed by interfering with the spare tire 12 that is flipped up and becomes a vertical wall at the time of a rear collision. The spare tire 12 is pushed further forward so that the high-voltage box 2 behind the seat back 7 is not affected, so that the direction of the spare tire 12 is controlled so as to suppress an increase in the weight of the vehicle body and the luggage compartment. The safety at the time of a rear collision can be further enhanced without narrowing the space of 10.
[0017]
At this time, by adjusting the shape of the rib 23 of the plate-like member 20 and the position of the simple joint portion 28 with the rear floor 11, the jumping direction of the spare tire 12 can be arbitrarily set, and it is also applicable to various vehicles. can do. Further, since the rear edge portion 24 of the plate-like member 20 is provided in front of the lower edge portion 19 of the inclined wall 16 of the spare tire pan 13, the substantial opening area of the spare tire pan 13 is not reduced. Furthermore, since the protruding height of the ribs 23 of the plate-like member 20 is set low, it is advantageous in that the protruding amount to the upper surface of the rear floor 11 can be minimized.
[0018]
The present invention is not limited to the above-described embodiment. For example, the plate-like member 20 is not provided with the ribs 23 but is rigid in the joint portion 21 and the protruding portion 22 due to a difference in plate thickness or by overlapping two sheets. You may make it have a difference.
[0019]
Moreover, as shown in FIG. 5, it is good also as the plate-shaped member 30 which has a hinge structure. Specifically, the rear plate member 32 is connected to the rear edge portion 33 parallel to the vehicle width direction of the front plate member 31 in contact with the rear floor 11 so as to be rotatable in the vertical direction. By making the turning portion along the rear edge portion 33 the folding line 26, the folding line of the plate-like member 30 can be reliably provided at a desired position, and the jumping-up direction of the spare tire 12 can be controlled more reliably. Can do. In FIG. 5, the same parts as those in FIG. Furthermore, it is possible to simplify the elastic hinge structure having ribs or the like parallel to the vehicle width direction at the broken line portion.
[0020]
【The invention's effect】
As described above, according to the first aspect of the invention, at the time of a rear collision, the plate-like member is deformed by interfering with the spare tire that is flipped up, absorbs the kinetic energy of the spare tire, and Because the wall can be used as a wall to control the jumping direction of the spare tire, especially in the case of a vehicle with a load behind the seat back, the impact on the load is avoided and safety in the event of a rear collision There is an effect of further increasing. In addition, since the plate-shaped member is provided along the upper surface of the rear floor without narrowing the opening of the spare tire pan, the usability of the luggage compartment is not reduced.
[0021]
According to the invention described in claim 2, since the deformation stress can be concentrated between the fixed portion and the protruding portion, and the bending of the plate-like member can be arbitrarily generated, the jumping of the spare tire is controlled. In addition to improving safety at the time of a rear collision, there are effects that can be applied to various vehicles.
