Description

本発明は、車両の後部構造に関し、特に高電圧バッテリと車両後部との間に空間部を有する車両の後部構造に関する。   The present invention relates to a vehicle rear structure, and more particularly to a vehicle rear structure having a space between a high voltage battery and a vehicle rear.

電気自動車、ハイブリッド自動車などの電動駆動源となる高電圧バッテリユニットを備えた車両が種々提案されている。これら車両では、車両後方からの衝突や車両側方からの衝突から高電圧バッテリユニットを保護するために、高電圧バッテリを車両の基部となる左右のリアサイドメンバの間に配置することが多い。そのため、高電圧バッテリユニットと車両後部との間には空間ができることから、車両に必要な装備品を同空間内に配置して車両に搭載している。しかし、高電圧バッテリユニットとこれら装備品とを車両前後方向や車両幅方向の同一平面内に並べて配置すると、車両後方から後突されて車両後部が変形してしまうと、車両後部と高電圧バッテリユニット間にある装備品が車両前方や幅方向に移動して高電圧バッテリユニットを損傷させる事が想定される。そこで、車両後部と高電圧バッテリユニットの間に配置される装備品と高電圧バッテリユニットとを車両上下方向にオフセットして配置したレイアウト構造の車両が特許文献１で提案されている。   Various vehicles including a high voltage battery unit serving as an electric drive source such as an electric vehicle and a hybrid vehicle have been proposed. In these vehicles, in order to protect the high voltage battery unit from a collision from the rear of the vehicle or a collision from the side of the vehicle, the high voltage battery is often disposed between the left and right rear side members that are the base of the vehicle. Therefore, since a space is created between the high voltage battery unit and the rear part of the vehicle, the equipment necessary for the vehicle is arranged in the space and mounted on the vehicle. However, if the high-voltage battery unit and these accessories are arranged side by side in the same plane in the vehicle front-rear direction and the vehicle width direction, the rear part of the vehicle and the high-voltage battery It is assumed that the equipment between the units moves in the front or width direction of the vehicle and damages the high voltage battery unit. Therefore, Patent Document 1 proposes a vehicle having a layout structure in which equipment and a high voltage battery unit arranged between the rear portion of the vehicle and the high voltage battery unit are arranged offset in the vehicle vertical direction.

特開２００８−２７３２７９号公報JP 2008-273279 A

特許文献１のように、高電圧バッテリユニットと装備品とを車両上下方向にオフセットして配置すれば、衝突時に装備品と高電圧バッテリとが衝突するのを回避できる。しかし、特許文献１の場合、高電圧バッテリユニットの下方に装備品を配置しているため、メンテナンスを伴う装備品を配置するには不向きであり、配置する装備品が限定されてしまう。また、スライド機構などを設けることで、高電圧バッテリユニットの下方の装備品を移動することは可能であるが、その分コストや設置スペースが嵩んでしまう。   If the high voltage battery unit and the equipment are offset in the vertical direction of the vehicle as in Patent Document 1, it is possible to avoid the equipment and the high voltage battery from colliding at the time of the collision. However, in the case of Patent Document 1, since the equipment is arranged below the high-voltage battery unit, it is unsuitable for arranging equipment with maintenance, and the equipment to be arranged is limited. Further, by providing a slide mechanism or the like, it is possible to move the equipment below the high voltage battery unit, but the cost and installation space increase accordingly.

本発明は、低コスト、省スペースで衝突時における装備品と高電圧バッテリユニットの衝突を回避して衝突保護性能を確保しながらも装備品のメンテナンス性の高い車両の後部構造を提供することを、その目的とする。   It is an object of the present invention to provide a rear structure of a vehicle that is low in cost and space-saving and has high maintainability of equipment while ensuring collision protection performance by avoiding collision between equipment and a high-voltage battery unit at the time of collision. And its purpose.

本発明に係る車両の後部構造において、車両後部は、車両幅方向に位置し車両前後方向に延在する複数のリアサイドメンバと、車両幅方向に延在しリアフロアよりも下方でリアサイドメンバに接合されたシャーシクロスメンバを有し、装備品とシャーシクロスメンバとが対向するように配置したことを特徴としている。
本発明に係る車両の後部構造において、車両後部は、車両幅方向に位置し、車両前後方向に延在する複数のリアサイドメンバと、車両幅方向に延在しリアサイドメンバの後端に接合されたリアバンパビームと、車両幅方向に延在しリアバンパビームよりも車両前方よりに配置され、リアフロアよりも下方でリアサイドメンバに接合されたフロアクロスメンバと、車両前後方向に延在しリアバンパビームとフロアクロスメンバに接合されたリアセンタメンバを有し、装備品を、リアバンパビームとフロアクロスメンバとリアセンタメンバと対向するように、リアバンパビームとフロアクロスメンバとリアセンタメンバの間に配置したことを特徴としている。 The rear structure of the vehicle according to the present invention includes a high voltage battery unit disposed on the rear floor of the vehicle, a vehicle rear portion positioned behind the rear end of the high voltage battery unit, and a rear end of the high voltage battery unit. The equipment is arranged between the rear part of the vehicle, and the equipment is arranged so that the upper part is located below the rear floor, and is offset with respect to the high voltage battery unit in the longitudinal direction of the vehicle. It is characterized by that.
In the rear structure of the vehicle according to the present invention, the rear portion of the vehicle is joined to the plurality of rear side members positioned in the vehicle width direction and extending in the vehicle front-rear direction, and to the rear side member extending in the vehicle width direction and below the rear floor. The chassis cross member is provided, and the equipment and the chassis cross member are arranged so as to face each other.
In the rear structure of the vehicle according to the present invention, the rear portion of the vehicle is positioned in the vehicle width direction and is joined to a plurality of rear side members extending in the vehicle front-rear direction and the rear end of the rear side member extending in the vehicle width direction. A rear bumper beam, a floor cross member that extends in the vehicle width direction and is arranged in front of the vehicle relative to the rear bumper beam, and is joined to the rear side member below the rear floor; and a rear bumper beam and floor cross that extend in the vehicle front-rear direction It has a rear center member joined to the member, and the equipment is arranged between the rear bumper beam, the floor cross member, and the rear center member so as to face the rear bumper beam, the floor cross member, and the rear center member.

本発明によれば、リアフロア上に配置された高電圧バッテリユニットの後端と、高電圧バッテリユニットの後端よりも車両後方に位置する車両後部との間で、その上部がリアフロアよりも下方に位置するよう装備品を配置して、装備品を高電圧バッテリユニットに対して車両上下方向と車両前後方向にオフセットして配置したので、後部衝突時において、車両後部が変形して装備品が押されても、リアフロアの下方で移動するため、衝突時における装備品と高電圧バッテリユニットの衝突を回避して衝突保護性能を確保することができるとともに、衝突前において、装備品は高電圧バッテリユニットに対して車両前後方向にオフセットされた状態であるため、移動手段を設けることなく装備品へのメンテナンス作業が可能となり、低コスト、省スペースで装備品のメンテナンス性を高めることができる。   According to the present invention, between the rear end of the high-voltage battery unit disposed on the rear floor and the rear of the vehicle positioned behind the rear end of the high-voltage battery unit, the upper portion is below the rear floor. Since the equipment is arranged so that it is positioned and the equipment is offset with respect to the high-voltage battery unit in the vehicle vertical direction and the vehicle front-rear direction, the rear part of the vehicle is deformed and the equipment is pushed by the rear collision. However, since it moves below the rear floor, it is possible to avoid collision between the equipment and the high-voltage battery unit at the time of the collision, and to ensure the collision protection performance, and before the collision, the equipment is the high-voltage battery unit. Since the vehicle is offset in the longitudinal direction of the vehicle, maintenance work on the equipment can be performed without providing moving means, and the cost is low. It is possible to improve the maintenance of the equipment in space.

以下、図面を用いて本発明に係る実施形態について説明する。
図１，図２に示す車両１は、走行駆動源として電動駆動源となるモータを有する電気自動車である。車両１の車室内に位置するリアシート８よりも後方には、リアフロア２が配置されている。リアフロア２は、矢印Ａで示す車両幅方向に位置し、矢印Ｂで示す車両前後方向に延在する複数のリアサイドメンバ４，５に、フロア上面２Ａ側から溶接などによって接合されて固定されている。リアフロア２の後端２Ｂには、車両後部６を構成するリアエンドパネル９が接合されている。フロア上面２Ａには、高電圧バッテリユニット３が、リアサイドメンバ４，５の間で、リアシート８寄りに配置されている。 Embodiments according to the present invention will be described below with reference to the drawings.
A vehicle 1 shown in FIGS. 1 and 2 is an electric vehicle having a motor as an electric drive source as a travel drive source. A rear floor 2 is arranged behind the rear seat 8 located in the vehicle interior of the vehicle 1. The rear floor 2 is positioned in the vehicle width direction indicated by the arrow A, and is fixed to the plurality of rear side members 4 and 5 extending in the vehicle front-rear direction indicated by the arrow B by welding or the like from the floor upper surface 2A side. . A rear end panel 9 constituting the vehicle rear portion 6 is joined to the rear end 2B of the rear floor 2. On the floor upper surface 2 </ b> A, the high voltage battery unit 3 is disposed near the rear seat 8 between the rear side members 4 and 5.

高電圧バッテリユニット３は、複数のバッテリーセルをモジュール化したものを複数備えたもので、その外部は図示しないケーシングで覆われた周知のものである。本形態において、高電圧バッテリユニット３の後端３Ａとリアエンドパネル９の間には空間１０が形成され、この空間１０を荷室として利用することができる。高電圧バッテリユニット３をリアサイドメンバ４，５の間に配置するのは、電気自動車において高電圧バッテリユニット３が破損すると走行不能になるため、衝突などの衝撃から保護するためである。   The high voltage battery unit 3 includes a plurality of modularized battery cells, and the outside thereof is a well-known unit covered with a casing (not shown). In this embodiment, a space 10 is formed between the rear end 3A of the high-voltage battery unit 3 and the rear end panel 9, and this space 10 can be used as a luggage compartment. The reason why the high voltage battery unit 3 is disposed between the rear side members 4 and 5 is that the high voltage battery unit 3 is damaged in the electric vehicle and cannot travel, so that it is protected from an impact such as a collision.

高電圧バッテリユニット３の後端３Ａとリアエンドパネル９の間には、装備品として、例えば補器用バッテリ７が配置されている。補器用バッテリ７は、メンテナンスが必要な装備品の１つである。補器用バッテリ７は、その上部７Ａがリアフロア２よりも下方に位置し、その前端７Ｂが高電圧バッテリユニット３の後端３Ａよりも車両後方側に位置し、高電圧バッテリユニット３に対して車両前後方向Ｂと矢印Ｃで示す車両上下方向にオフセットされて配置されている。   Between the rear end 3 </ b> A of the high voltage battery unit 3 and the rear end panel 9, for example, an auxiliary battery 7 is disposed as an accessory. The auxiliary battery 7 is one of the equipments that require maintenance. The auxiliary battery 7 has an upper portion 7A positioned below the rear floor 2 and a front end 7B positioned on the vehicle rear side of the rear end 3A of the high voltage battery unit 3 so that the vehicle They are arranged offset in the vehicle vertical direction indicated by the front-rear direction B and the arrow C.

車両後部６は、リアサイドメンバ４，５、リアエンドパネル９、車両幅方向Ａに延在しリアフロア２よりも下方でリアサイドメンバ４，５に、その両端１１Ａ,１１Ｂが接合されたフロアクロスメンバ１１と、車両幅方向Ａに延在しリアサイドメンバ４，５の後端４Ａ、５Ａに接合されたリアバンパビーム１３と、車両前後方向Ａに延在しリアバンパビーム１３とフロアクロスメンバ１１に、その両端が接合されたリアセンタメンバ１４と、車両幅方向Ａに延在し、リアサイドメンバ４，５にその両端１２Ａ,１２Ｂが固定されたシャーシクロスメンバ１２を備えている。リアバンパビーム１３よりも車両後方側には、リアバンパ１５が、リアエンドパネル９とリアバンパビーム１３から下方に延びるブラケット１６に取付けられて配置されている。   The vehicle rear portion 6 includes a rear side member 4, 5, a rear end panel 9, a floor cross member 11 that extends in the vehicle width direction A and is below the rear floor 2 and is joined to the rear side members 4, 5 at both ends 11 A, 11 B. The rear bumper beam 13 extending in the vehicle width direction A and joined to the rear ends 4A and 5A of the rear side members 4 and 5 and the rear bumper beam 13 and the floor cross member 11 extending in the vehicle front-rear direction A have both ends thereof. A joined rear center member 14 and a chassis cross member 12 extending in the vehicle width direction A and having both ends 12A and 12B fixed to the rear side members 4 and 5 are provided. A rear bumper 15 is attached to a rear end panel 9 and a bracket 16 extending downward from the rear bumper beam 13 on the rear side of the vehicle with respect to the rear bumper beam 13.

高電圧バッテリユニット３の後端３Ａとリアエンドパネル９の間で、かつ、リアサイドメンバ５とリアセンタメンバ１４の間に配置するリアフロア２には、開口２Ｃが形成されている、この開口２Ｃには、装備品収納部となるケース１７が配置されている。ケース１７は、その上部が開口され、これ以外の５面が塞がれていて、上部開口周囲に形成されたフランジ部１７Ａがリアサイドメンバ５とリアセンタメンバ１４とフロア上面２Ａに接合されることで、リアフロア２よりも車両下方に突出して形成されている。このケース１７内には補器用バッテリ７が収納されて、図示しないボルトなどで固定される。ケース１７の深さは、補器用バッテリ７を収納したときに、補器用バッテリ７の上部７Ａが高電圧バッテリユニット３の後端３Ａと車両上下方向Ｃにおいてオーバーラップしないように設定されている。ケース１７の上部には開閉式の蓋２０が着脱可能に装着される。この蓋２０は、メンテナンス時以外はケース１７の上面を塞ぎフロア上面２Ａの一部を構成する。作業者は、メンテナンス時になると、この蓋２０を開いて離脱して補器用バッテリ７に対するメンテナンス作業を行う。   An opening 2C is formed in the rear floor 2 disposed between the rear end 3A of the high-voltage battery unit 3 and the rear end panel 9 and between the rear side member 5 and the rear center member 14. The opening 2C A case 17 serving as an equipment storage unit is disposed. The upper portion of the case 17 is opened and the other five surfaces are closed, and the flange portion 17A formed around the upper opening is joined to the rear side member 5, the rear center member 14, and the floor upper surface 2A. Thus, it is formed so as to protrude below the vehicle from the rear floor 2. The auxiliary battery 7 is accommodated in the case 17 and is fixed with a bolt (not shown). The depth of the case 17 is set so that the upper part 7A of the auxiliary battery 7 does not overlap the rear end 3A of the high voltage battery unit 3 in the vehicle vertical direction C when the auxiliary battery 7 is stored. An openable / closable lid 20 is detachably mounted on the upper portion of the case 17. The lid 20 closes the upper surface of the case 17 and constitutes a part of the floor upper surface 2A except during maintenance. When it is time for maintenance, the operator opens and removes the lid 20 to perform maintenance work on the auxiliary battery 7.

フロアクロスメンバ１１は、リアフロア２よりも車両下方で高電圧バッテリユニット３の下部と対向配置されている。高電圧バッテリユニット３は、リアフロア２とリアサイドメンバ４，５に図示しないボルトなどの締結部材で固定されている。シャーシクロスメンバ１２は、フロアクロスメンバ１１よりも車両下方側で、かつ、ケース１７内に収納された補器用バッテリ７と車両前方側で対向するように、フロアクロスメンバ１１よりも車両後方側に配置されている。   The floor cross member 11 is disposed below the rear floor 2 so as to face the lower portion of the high voltage battery unit 3 below the vehicle. The high voltage battery unit 3 is fixed to the rear floor 2 and the rear side members 4 and 5 with fastening members such as bolts (not shown). The chassis cross member 12 is on the vehicle lower side of the floor cross member 11 and on the vehicle rear side of the floor cross member 11 so as to face the auxiliary battery 7 housed in the case 17 on the vehicle front side. Is arranged.

このような構成において、車両後部６が車両後方から衝突荷重Ｆを受けると、リアバンパ１５、リアバンパビーム１３、リアエンドパネル９、リアフロア後端２Ｂが車両前方に向かって変形する。このとき、補器用バッテリ７は高電圧バッテリユニット３よりも車両後方側に配置されているので、図３に示すように、高電圧バッテリユニット３よりも先に衝突荷重Ｆを受け、車両前方側（車室内側）へと押される。しかし、補器用バッテリ７は、リアフロア２よりも車両下方に配置されて高電圧バッテリユニット３と車両上下方向にオフセットされているので、衝突荷重Ｆを受けて車両前方側に移動しても、高電圧バッテリユニット３の後端３Ａと、その前端７Ａが衝突しない。つまり、車両後部６が変形して補器用バッテリ７が押されても、補器用バッテリ７はリアフロア２の下方で移動するため、車両後方からの衝突時における補器用バッテリ７と高電圧バッテリユニット３の干渉を回避して衝突保護性能を確保することができる。   In such a configuration, when the vehicle rear portion 6 receives a collision load F from the rear of the vehicle, the rear bumper 15, the rear bumper beam 13, the rear end panel 9, and the rear floor rear end 2B are deformed toward the front of the vehicle. At this time, since the auxiliary battery 7 is disposed on the vehicle rear side with respect to the high voltage battery unit 3, as shown in FIG. 3, it receives the collision load F before the high voltage battery unit 3, and the vehicle front side. It is pushed to the (vehicle interior side). However, since the auxiliary battery 7 is disposed below the rear floor 2 and offset from the high-voltage battery unit 3 in the vehicle vertical direction, even if the auxiliary battery 7 moves to the vehicle front side in response to the collision load F, the auxiliary battery 7 The rear end 3A of the voltage battery unit 3 and its front end 7A do not collide. That is, even if the rear part 6 of the vehicle is deformed and the auxiliary battery 7 is pushed, the auxiliary battery 7 moves below the rear floor 2, so that the auxiliary battery 7 and the high voltage battery unit 3 at the time of a collision from the rear of the vehicle. The collision protection performance can be ensured by avoiding the interference.

衝突荷重Ｆを受けた補器用バッテリ７は、車両前方側へと移動するが、その移動方向にはシャーシクロスメンバ１２が対向配置されているので、シャーシクロスメンバ１２に衝突して衝突荷重Ｆが伝達される。シャーシクロスメンバ１２はリアサイドメンバ４，５に連結されているので、シャーシクロスメンバ１２に加わる衝突荷重Ｆはリアサイドメンバ４，５へと伝達され、衝撃が分散される。   The auxiliary battery 7 that has received the collision load F moves to the front side of the vehicle. However, since the chassis cross member 12 is opposed to the vehicle in the moving direction, the collision load F is collided with the chassis cross member 12. Communicated. Since the chassis cross member 12 is connected to the rear side members 4 and 5, the collision load F applied to the chassis cross member 12 is transmitted to the rear side members 4 and 5, and the impact is dispersed.

衝突前において、補器用バッテリ７は高電圧バッテリユニット３に対して車両前後方向Ｂにオフセットされた状態であるため、特別に移動手段を設けることなく、蓋２０を開くことで補器用バッテリ７へのメンテナンス作業が可能となるため、低コスト、省スペースで装備品の一例である補器用バッテリ７のメンテナンス性を高めることができる。   Before the collision, since the auxiliary battery 7 is offset in the vehicle front-rear direction B with respect to the high voltage battery unit 3, the auxiliary battery 7 can be opened by opening the lid 20 without providing any special moving means. Therefore, it is possible to improve the maintainability of the auxiliary battery 7 which is an example of the equipment with low cost and space saving.

また、後方からの衝突に際し、その衝突荷重Ｆは高電圧バッテリユニット３よりも先に補器用バッテリ７が受けるが、補器用バッテリ７は、リアサイドメンバ５、シャーシクロスメンバ１２、リアバンパビーム１３、リアセンタメンバ１４の間に配置されているので、取付け剛性を高められると共に、衝突時の衝突荷重Ｆを確実にリアサイドメンバ５に伝達することができる。   Further, in the case of a collision from the rear, the collision load F is received by the auxiliary battery 7 before the high voltage battery unit 3, and the auxiliary battery 7 includes the rear side member 5, the chassis cross member 12, the rear bumper beam 13, the rear Since it is disposed between the center members 14, the mounting rigidity can be increased and the collision load F at the time of collision can be reliably transmitted to the rear side member 5.

本形態では、車両後部６にリアセンタメンバ１４を備えた形態を用いて説明したが、リアセンタメンバ１４を備えていない車両１に適用してもよい。この場合、補器用バッテリ７を収納するケース１７は、リアフロア２に形成した開口７Ｃの周囲に取り付ける構造としてもよいが、シャーシクロスメンバ１２とは車両前方側で対向配置することで、車両後方からの衝突荷重Ｆを受けて補器用バッテリ７が車両前方側に移動しても、その移動をシャーシクロスメンバ１２で受け止めると共に、その際の衝突荷重Ｆをリアサイドメンバ５へと伝達することができる。   Although this embodiment has been described using a form in which the rear center member 14 is provided in the rear portion 6 of the vehicle, the present invention may be applied to the vehicle 1 that does not have the rear center member 14. In this case, the case 17 for storing the auxiliary battery 7 may be attached to the periphery of the opening 7C formed in the rear floor 2. However, the case 17 is arranged to face the chassis cross member 12 on the front side of the vehicle so that the case 17 is rearward. Even when the auxiliary battery 7 moves to the front side of the vehicle in response to the collision load F, the movement can be received by the chassis cross member 12 and the collision load F at that time can be transmitted to the rear side member 5.

本形態では、電動駆動源を有する電気自動車を車両１として例示したが、本発明の適用は電気自動車に限定されるものではなく、内燃機関と電動モータを走行駆動源として用いる、所謂ハイブリッド車やプラグインハイブリッド車にも適用可能である。   In this embodiment, an electric vehicle having an electric drive source is exemplified as the vehicle 1, but the application of the present invention is not limited to the electric vehicle, and a so-called hybrid vehicle using an internal combustion engine and an electric motor as a travel drive source, It can also be applied to plug-in hybrid vehicles.
