Description

本発明は、主としてハイブリッド車におけるバッテリーの取付構造に関する。   The present invention mainly relates to a battery mounting structure in a hybrid vehicle.

自動車が後面から衝突などで衝撃を受けたときに、衝撃を和らげるために種々の開発がなされている。例えば特許文献１では、好適に後突衝撃を吸収しながら、既存の車両用シートに後付け可能な後突衝撃吸収ユニットが開示されている。   Various developments have been made to mitigate the impact when the automobile is impacted from the rear by a collision or the like. For example, Patent Document 1 discloses a rear impact impact absorbing unit that can be retrofitted to an existing vehicle seat while preferably absorbing the rear impact impact.

また、自動車のリアフロアパネルにスペースタイヤを格納するための凹み部が形成されている。このようなリアフロアパネルを備えた車両において、後面衝突時に、その凹み部の前方に配置された燃料タンクを潰してしまうことがないよう、その凹み部の前壁に前上がりの傾斜面を取り付けておき、後方から大きな力がスペアタイヤに加わった際、スペアタイヤの前側部分を傾斜面に沿って荷室フロア上に乗り上げようとしたものがある。   Moreover, the recessed part for storing a space tire is formed in the rear floor panel of a motor vehicle. In a vehicle equipped with such a rear floor panel, in order to prevent the fuel tank disposed in front of the recessed portion from being crushed in the event of a rear collision, an inclined surface that rises forward is attached to the front wall of the recessed portion. In addition, when a large force is applied to the spare tire from the rear, there is an attempt to ride the front portion of the spare tire on the cargo floor along the inclined surface.

特許文献２では、そのようなタイプの車両をハイブリッド車とガソリンエンジン車とで車体を共用可能とするため、第２の傾斜面を備えるブレースを、前壁の傾斜面の後方に選択的に固定可能とするものが開示されている。それによれば、ブレースの有無を選択するだけで、特にハイブリッド車の場合に客室と荷室との間に設置されたバッテリーなどの電装品にスペアタイヤが突き当たることを防止している。   In Patent Document 2, a brace having a second inclined surface is selectively fixed to the rear of the inclined surface of the front wall so that the vehicle body can be shared between a hybrid vehicle and a gasoline engine vehicle. What is made possible is disclosed. According to this, it is possible to prevent the spare tire from hitting an electrical component such as a battery installed between the passenger compartment and the cargo compartment, particularly in the case of a hybrid vehicle, by simply selecting the presence or absence of braces.

特開２００９−１２０９号公報（フロント頁）JP 2009-1209 A (front page) 特開２００６−２１３２５２号公報（段落［０００２］、［０００６］、［０００７］）JP 2006-213252 A (paragraphs [0002], [0006], [0007])

一般に、ハイブリッド車にあっては、リアフロアパネルにおける縦壁部の前側にシートフレームが配備され、そのシートフレームとリアフロアパネルとの間にバッテリーが取り付けられ、リアフロアパネルの縦壁部を挟んでバッテリーと対向する位置に燃料タンクが取り付けられている。   In general, in a hybrid vehicle, a seat frame is provided in front of the vertical wall portion of the rear floor panel, a battery is attached between the seat frame and the rear floor panel, and the battery is sandwiched between the vertical wall portion of the rear floor panel. A fuel tank is attached to the opposite position.

ハイブリッド車が小型である場合、燃料タンクとバッテリーとの間の距離が短いため、後面から力が加わると、燃料タンクが左側面から見て反時計回りに回転し、燃料タンクとバッテリーとが干渉する。すると、リアフロアパネルの縦壁部は前にバッテリーがあるため変形が抑制され、バッテリーと燃料タンクが早期に強く干渉し合う。   When the hybrid vehicle is small, the distance between the fuel tank and the battery is short, so if force is applied from the rear, the fuel tank rotates counterclockwise when viewed from the left side, and the fuel tank and battery interfere. To do. Then, since the vertical wall portion of the rear floor panel has a battery in front, deformation is suppressed, and the battery and the fuel tank strongly interfere with each other at an early stage.

そのため、燃料タンクやバッテリーケース、さらには車両ボディを補強しなければならず、車体そのものの重量が増加し燃費が悪くなり、資源の無駄使いや対策コストの増加を招いてしまう。   Therefore, the fuel tank, battery case, and further the vehicle body must be reinforced, the weight of the vehicle body itself increases, fuel efficiency deteriorates, and resources are wasted and countermeasure costs are increased.

そこで、本発明は、資源を無駄使いせずに、車両の後ろ側から力が加わった場合にバッテリー等を保護することができるバッテリーの取付構造を提供することを目的とする。   Accordingly, an object of the present invention is to provide a battery mounting structure that can protect a battery and the like when a force is applied from the rear side of the vehicle without wasting resources.

上記目的を達成するために、本発明は、リアフロアパネルに対してバッテリーが載置されており、バッテリーをリアフロアパネルで囲うようにシートフレームが設置されており、バッテリーの上部がシートフレームに締結され、上記バッテリーの下前側縁部がリアフロアパネルに締結され、バッテリーの下後側縁部が後方からの荷重によりリアフロアパネルに離脱可能に取り付けられている、という特徴を有する。   In order to achieve the above object, according to the present invention, a battery is placed on a rear floor panel, a seat frame is installed so as to surround the battery with the rear floor panel, and an upper portion of the battery is fastened to the seat frame. The lower front edge of the battery is fastened to the rear floor panel, and the lower rear edge of the battery is detachably attached to the rear floor panel by a load from the rear.

本発明によれば、後ろから力が加わるとバッテリーの後下縁部がリアフロアパネルから外れて、バッテリーが前に変位するので、燃料タンクがリアフロアパネルに当たるまでの距離が長くなり、バッテリーや燃料タンクを変形し難くする。よって、後面衝突による保護を、資源を浪費せず、対策コストを増加させないで実現することができる。   According to the present invention, when a force is applied from behind, the rear lower edge of the battery is detached from the rear floor panel, and the battery is displaced forward. Therefore, the distance until the fuel tank hits the rear floor panel is increased, and the battery and the fuel tank Makes it difficult to deform. Therefore, protection by rear collision can be realized without wasting resources and increasing countermeasure costs.

In the drawing, Fr, RH, and Up respectively indicate the front side of the vehicle and the right side of the vehicle width direction, and vertically upward, and the same or corresponding members and parts are denoted by the same reference numerals.

図１に示されているように、本発明の実施形態に係るバッテリー２０の取付構造では、リアフロアパネル１０に対してバッテリー２０が載置されており、バッテリー２０をリアフロアパネル１０とで囲むようにシートフレーム３０が設置されている。そして、バッテリー２０の上部２１がシートフレーム３０に締結され、バッテリー２０の下前側縁部２２がリアフロアパネル１０に締結され、バッテリー２０の下後側縁部２３が後方からの荷重によりリアフロアパネル１０に離脱可能に取り付けられている。   As shown in FIG. 1, in the battery 20 mounting structure according to the embodiment of the present invention, the battery 20 is placed on the rear floor panel 10 so that the battery 20 is surrounded by the rear floor panel 10. A seat frame 30 is installed. Then, the upper part 21 of the battery 20 is fastened to the seat frame 30, the lower front edge 22 of the battery 20 is fastened to the rear floor panel 10, and the lower rear edge 23 of the battery 20 is attached to the rear floor panel 10 by a load from the rear. Removably attached.

以下詳細に説明すると、リアフロアパネル１０は、概ね、前側から後方に、下部１１、縦壁部１２、上部１３の順に折り曲げられて形成されてなる。バッテリー２０は実際にはバッテリーケースに収容されているところ、図２ではバッテリーケースで示しており、その内部構造については示していない。   As will be described in detail below, the rear floor panel 10 is generally formed by bending from the front side to the rear side in the order of the lower part 11, the vertical wall part 12, and the upper part 13. Although the battery 20 is actually housed in the battery case, it is shown as a battery case in FIG. 2, and its internal structure is not shown.

バッテリー２０は、リアフロアパネル１０の縦壁部１２の前側に、縦壁部１２と僅かな距離を保って、下部１１に載置されている。バッテリー２０は車幅方向を長手とする略直方体を有しており、バッテリー２０のうちリアフロアパネル１０の下部１１に対して、前側では下前側縁部２２が対向し、後側では下後側縁部２３が対向している。図１に示されているように、下前側縁部２２は、前側に延びる脚部２２Ａを複数有しており、各脚部２２Ａは車幅方向に離隔している。これらの脚部２２Ａは、例えばリアフロアパネル１０の下部１１に溶接やボルトなどで離脱不能に取り付けられている。   The battery 20 is placed on the lower portion 11 on the front side of the vertical wall portion 12 of the rear floor panel 10 while maintaining a slight distance from the vertical wall portion 12. The battery 20 has a substantially rectangular parallelepiped having a longitudinal direction in the vehicle width direction. The lower front edge 22 is opposed to the lower portion 11 of the rear floor panel 10 in the battery 20 on the front side, and the lower rear edge on the rear side. The part 23 is facing. As shown in FIG. 1, the lower front side edge portion 22 has a plurality of leg portions 22 </ b> A extending to the front side, and each leg portion 22 </ b> A is separated in the vehicle width direction. These leg portions 22A are attached to the lower portion 11 of the rear floor panel 10 so as not to be detached by welding or bolts, for example.

バッテリー２０の下後側縁部２３は左右にそれぞれ脚部２３Ａを有しており、各脚部２３Ａは図３に拡大して示されているように、後ろ側に開口２３Ｂを有する。リアフロアパネル１０の下部１１には、バッテリー２０の設置位置、詳細には各脚部２３Ａに対応した位置に、係止具１１Ａが立設されている。それゆえ、バッテリー２０が車両前方に変位すると、各脚部２３Ａは図３の点線のようにあたかも係止具１１Ａが開口２３Ｂからすり抜けて、脚部２３Ａが係止具１１Ａから離脱する。脚部２３Ａには例えばＵ字状の溝が形成されている。   The lower rear edge 23 of the battery 20 has leg portions 23A on the left and right sides, and each leg portion 23A has an opening 23B on the rear side as shown in an enlarged view in FIG. At the lower portion 11 of the rear floor panel 10, a locking tool 11 </ b> A is erected at the installation position of the battery 20, specifically at a position corresponding to each leg portion 23 </ b> A. Therefore, when the battery 20 is displaced forward of the vehicle, each leg portion 23A is disengaged from the opening 23B and the leg portion 23A is detached from the latching tool 11A as shown by the dotted line in FIG. For example, a U-shaped groove is formed in the leg portion 23A.

バッテリー２０のリアフロアパネル１０への載置手順としては各種考えられ、例えば、バッテリー２０を前側からリアフロアパネル１０に所定の角度をなすように各開口２３Ｂに係止具１１Ａを通した後に、バッテリー２０をリアフロアパネル１０に載置し、その後、下前側縁部２２の脚部２２Ａをリアフロアパネル１０に固着する。   Various procedures for placing the battery 20 on the rear floor panel 10 are conceivable. For example, after the battery 20 is passed through the openings 11B through the openings 23B so as to form a predetermined angle from the front side to the rear floor panel 10, the battery 20 Is mounted on the rear floor panel 10, and then the leg portion 22 </ b> A of the lower front side edge portion 22 is fixed to the rear floor panel 10.

バッテリー２０とシートフレーム３０との関係を説明するために、先ずシートフレーム３０それ自体について説明する。シートフレーム３０は図示しない後部シートを支持するものである。   In order to explain the relationship between the battery 20 and the seat frame 30, the seat frame 30 itself will be described first. The seat frame 30 supports a rear seat (not shown).

シートフレーム３０は、例えば図１に示されているように、何れも主要部分が車幅方向に延びる第１フレーム部３１と第２フレーム部３２と第３フレーム部３３とで構成されている。第１フレーム部３１と第２フレーム部３２とは車両前後方向に離隔されており、その両端で前後方向に延びて接続されている。第２フレーム部３２と第３フレーム部３３とは上下方向に離隔され、第３フレーム部３３の両端は何れも第２フレーム部３２に接続されている。図１には示していないが図２に示すように、クロスメンバー３６がリアフロアパネル１０上に車幅方向に延びるように設けられているので、第３フレーム部３３はクロスメンバー３６にブラケット３３Ａを介して固定されても良い。第３フレーム部３３のブラケット３３Ａとバッテリー２０の脚部２２Ａとをクロスメンバー３６へ固定する場合、図２に示すように、その固定箇所が同じになるようにブラケット３３Ａと脚部２２Ａとが部分的に重ね合わさっても良い。また、図示しないが、第３フレーム部３３はブラケット３３Ａを介在してリアフロアパネル１０に固定されていても構わない。シートフレーム３０は側面視においてほぼ直角三角形の頂点に配置されて車幅方向に延びており、バッテリー２０をこのシートフレーム３０とリアフロアパネル１０とで囲っている。   For example, as shown in FIG. 1, the seat frame 30 includes a first frame portion 31, a second frame portion 32, and a third frame portion 33, each of which has a main portion extending in the vehicle width direction. The first frame portion 31 and the second frame portion 32 are spaced apart in the vehicle front-rear direction, and are connected so as to extend in the front-rear direction at both ends thereof. The second frame part 32 and the third frame part 33 are spaced apart in the vertical direction, and both ends of the third frame part 33 are connected to the second frame part 32. Although not shown in FIG. 1, as shown in FIG. 2, since the cross member 36 is provided on the rear floor panel 10 so as to extend in the vehicle width direction, the third frame portion 33 has a bracket 33 </ b> A attached to the cross member 36. It may be fixed via. When the bracket 33A of the third frame portion 33 and the leg portion 22A of the battery 20 are fixed to the cross member 36, as shown in FIG. 2, the bracket 33A and the leg portion 22A are partially arranged so that the fixing locations are the same. May be overlapped. Although not shown, the third frame portion 33 may be fixed to the rear floor panel 10 with a bracket 33A interposed therebetween. The seat frame 30 is arranged at the apex of a substantially right triangle in a side view and extends in the vehicle width direction, and the battery 20 is surrounded by the seat frame 30 and the rear floor panel 10.

ここで、第１フレーム部３１と第２フレーム部３２とはほぼ同じ高さに設けられているが、第１フレーム部３１はバッテリー２０の後ろ側上方に配置されており、第２フレーム部３１は第１フレーム部３１の前側に設けられており、第１フレーム部３１と第２フレーム部３２とは周状をなしている。第３フレーム部３３は、第２フレーム部３２に左右両端でそれぞれ取り付けられ、下方に延びてリアフロアパネル１０に近づくと角度を変えて車幅方向に延びてつながっている。   Here, although the first frame portion 31 and the second frame portion 32 are provided at substantially the same height, the first frame portion 31 is disposed on the upper rear side of the battery 20, and the second frame portion 31. Is provided on the front side of the first frame portion 31, and the first frame portion 31 and the second frame portion 32 form a circumferential shape. The third frame portion 33 is attached to the second frame portion 32 at both the left and right ends, and extends downward and is connected to extend in the vehicle width direction at a different angle when approaching the rear floor panel 10.

第１フレーム部３１は、バッテリー２０の上部に離脱不能に取り付けられ、かつリアフロアパネル１０の上部１３に固定されている。具体的には、図４に示すように、第１フレーム部３１には後ろに向けて延びたブラケット３１Ａが溶接などで取り付けられており、貫通穴を有するブラケット３１Ａはちょうどバッテリー２０の上部２１と対向して、螺子などにより螺着されている。ブラケット３１Ａは車幅方向に間隔をあけて複数、図１に示す場合では二つ設けられている。   The first frame portion 31 is attached to the upper portion of the battery 20 so as not to be detached, and is fixed to the upper portion 13 of the rear floor panel 10. Specifically, as shown in FIG. 4, a bracket 31 </ b> A extending rearward is attached to the first frame portion 31 by welding or the like, and the bracket 31 </ b> A having a through hole is exactly the same as the upper portion 21 of the battery 20. Oppositely, it is screwed by a screw or the like. A plurality of brackets 31A are provided at intervals in the vehicle width direction, and two brackets 31A are provided in the case shown in FIG.

また、このシートフレーム３０のうち後ろ上にある第１フレーム部３１はリアフロアパネル１０の上部１３とほぼ同じ高さにあり、取付具としてのシートガゼット３５により車幅方向両側でそれぞれリアフロアパネル１０の上部１３に掛け渡されて、シートフレーム３０がリアフロアパネル１０にも取り外し不要に取り付けられている。   Further, the first frame portion 31 on the rear upper side of the seat frame 30 is substantially at the same height as the upper portion 13 of the rear floor panel 10, and the rear floor panel 10 is arranged on both sides in the vehicle width direction by seat gussets 35 as attachments. The seat frame 30 is attached to the rear floor panel 10 so as not to be removed.

図２に示されているように、燃料タンク４０が、リアフロアパネル１０の縦壁部１２を挟んでバッテリー２０と相対峙する位置に取り付けられている。また、図２に示されているように、車両後部は、バックドア５０を開くと、スペアタイヤ５１を格納するよう凹み部５２を設けたパネル５３が設置されており、そのパネル５３の下側にはキャニスター５４が設けられている。パネル５３の下側で、キャニスター５４と燃料タンク４０との間には中間ビーム５５が車幅方向に延びている。   As shown in FIG. 2, the fuel tank 40 is attached at a position facing the battery 20 across the vertical wall portion 12 of the rear floor panel 10. Further, as shown in FIG. 2, when the back door 50 is opened, a rear panel of the vehicle is provided with a panel 53 provided with a recessed portion 52 for storing the spare tire 51. Is provided with a canister 54. An intermediate beam 55 extends in the vehicle width direction between the canister 54 and the fuel tank 40 below the panel 53.

以上のように、本発明の実施形態に係るバッテリー２０の取付構造は、バッテリー２０をリアフロアパネル１０の縦壁部１２の前側に載置し、バッテリー２０のリアフロアパネル１０への各固定が、下前側縁部２２により脚部２２Ａで離脱不能に締結され、下後側縁部２３により脚部２３Ａで離脱可能に取り付けられ、そのバッテリー２０をリアフロアパネル１０の縦壁部１２とで囲むようにシートフレーム３０を配置して、バッテリー２０の上部２１をシートフレーム３０にブラケット３１Ａ等で離脱不能に締結する。   As described above, the mounting structure of the battery 20 according to the embodiment of the present invention is such that the battery 20 is placed on the front side of the vertical wall portion 12 of the rear floor panel 10 and each fixing of the battery 20 to the rear floor panel 10 is A seat that is fastened by a front edge 22 so as not to be detached at a leg 22A, is removably attached at a leg 23A by a lower rear edge 23, and surrounds the battery 20 with a vertical wall 12 of the rear floor panel 10. The frame 30 is arranged, and the upper part 21 of the battery 20 is fastened to the seat frame 30 with a bracket 31A or the like so as not to be detached.

このようなバッテリー２０の取付構造を採用することにより、万一、後面衝突などの衝撃により後ろ側から力が加わっても、燃料タンク４０とバッテリー２０とは強く干渉しない。詳細に説明すると、後ろから力（図３におけるＦの矢印）が加わると、車両左側面からみて燃料タンク４０がリアフロアパネル１０の上部１３と共に前側に移動しながら反時計回りに回転し、それに伴って縦壁部１２が前側に移動しても、バッテリー２０の下後側縁部２３が図３に点線で示すように、係止具１１Ａから外れてリアフロアパネル１０の下部１１から浮いて前のめりになるように移動する。図３のΔＸがその前方向の変位を示す。つまり、バッテリー２０が図示しないセンターフロアパネル側に、すなわち前側に逃げるように変位する。   By adopting such a battery 20 mounting structure, the fuel tank 40 and the battery 20 do not interfere strongly even if a force is applied from the rear side due to an impact such as a rear collision. More specifically, when a force (arrow F in FIG. 3) is applied from behind, the fuel tank 40 rotates counterclockwise while moving to the front side together with the upper portion 13 of the rear floor panel 10 as viewed from the left side of the vehicle. Even if the vertical wall portion 12 moves to the front side, the lower rear edge portion 23 of the battery 20 is detached from the locking tool 11A and floats from the lower portion 11 of the rear floor panel 10 as shown by the dotted line in FIG. Move to be. ΔX in FIG. 3 indicates the forward displacement. That is, the battery 20 is displaced so as to escape to the center floor panel side (not shown), that is, the front side.

このようにバッテリー２０が相対的に前側に移動して逃げることにより、バッテリー２０に与える影響が小さくなると共に、燃料タンク４０のスペースは小さくはなるが、変形する量が小さくなる。   As the battery 20 moves to the front side and escapes in this manner, the influence on the battery 20 is reduced and the space of the fuel tank 40 is reduced, but the amount of deformation is reduced.
