A pair of first reinforcing members and a second reinforcing member that connects the front ends of the first reinforcing members in the vehicle width direction are provided.

本発明の車両へのバッテリー搭載構造によれば、バッテリー搭載トレイを箱形状としたので、外的要件からその内部に搭載されるバッテリーを保護することができる。   According to the battery mounting structure for a vehicle of the present invention, since the battery mounting tray has a box shape, the battery mounted therein can be protected from external requirements.

また、本発明によれば、第１補強部材と第２補強部材をバッテリー搭載トレイに設けたことで、当該バッテリー搭載トレイ自体の剛性を高めることができる。   According to the present invention, the rigidity of the battery mounting tray itself can be increased by providing the first reinforcing member and the second reinforcing member on the battery mounting tray.

以下、本発明を適用した具体的な実施形態について図面を参照しながら詳細に説明する。   Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

バッテリー搭載トレイ２には、電気自動車として航続距離確保のため一定量のバッテリー１が搭載できること、及び、バッテリー保護のため路面と干渉し難いこと、リヤサスペンションと干渉しないこと、等が求められる。これらの要件を満たすために、本実施形態では、車両フロア下とリヤサスペンション５上のそれぞれにバッテリー１を搭載してバッテリー搭載量を確保し、またバッテリー１を車両高さ方向で段違いに搭載させて路面干渉及びリヤサスペンション５との干渉を回避させた構造としている。   The battery mounting tray 2 is required to be able to mount a certain amount of the battery 1 as an electric vehicle so as to secure a cruising distance, to be difficult to interfere with the road surface and not to interfere with the rear suspension, etc. for battery protection. In order to satisfy these requirements, in the present embodiment, a battery 1 is mounted under the vehicle floor and on the rear suspension 5 to secure the battery loading amount, and the battery 1 is mounted in a stepwise manner in the vehicle height direction. Thus, the road surface interference and the interference with the rear suspension 5 are avoided.

具体的には、バッテリー搭載トレイ２は、上面を開口させ且つ底部を有した平面視略矩形状をなす箱形トレイとされている。このバッテリー搭載トレイ２は、押し出し材により形成されており、それ自体の剛性が高められている。   Specifically, the battery-mounting tray 2 is a box-shaped tray having a substantially rectangular shape in plan view with an upper surface opened and a bottom portion. This battery mounting tray 2 is formed of an extruded material, and its own rigidity is enhanced.

また、バッテリー搭載トレイ２には、フロア下のほぼ全領域にバッテリー１を搭載させる第１搭載部６と、リヤサスペンション５上にバッテリー１を搭載させる第２搭載部７とが形成され、これら第１搭載部６と第２搭載部７を車両高さ方向で段違いとしている。第２搭載部７は、第１搭載部６よりも車両高さ方向で上方位置に設けられている。第１搭載部６は、第２搭載部７に比べてその面積が大きく、該第２搭載部７よりも大容量（或いはより多くの）バッテリーを搭載させることができる。また、第１搭載部６と第２搭載部７は、車両高さ方向に立ち上がる仕切り壁部８によって仕切られている。   The battery mounting tray 2 is formed with a first mounting portion 6 for mounting the battery 1 in almost the entire area under the floor and a second mounting portion 7 for mounting the battery 1 on the rear suspension 5. The first mounting portion 6 and the second mounting portion 7 are stepped in the vehicle height direction. The second mounting portion 7 is provided at an upper position in the vehicle height direction than the first mounting portion 6. The first mounting portion 6 has a larger area than the second mounting portion 7 and can mount a battery with a larger capacity (or more) than the second mounting portion 7. Moreover, the 1st mounting part 6 and the 2nd mounting part 7 are partitioned off by the partition wall part 8 which stands | starts up in a vehicle height direction.

そして、前記バッテリー搭載トレイ２には、図５から図７に示すように、車両用骨格フレーム４を構成するリヤサイドメンバ９に沿うように車両前後方向へ延在して設けられた一対の第１補強部材１０と、これら第１補強部材１０の前端同士を車幅方向に連結する第２補強部材１１と、が設けられている。   As shown in FIGS. 5 to 7, the battery-mounting tray 2 is provided with a pair of first first members that extend in the vehicle front-rear direction along the rear side member 9 that constitutes the vehicle frame 4.

第１補強部材１０は、第２搭載部７の車幅方向両脇に車両前後方向に配置され、前記リヤサイドメンバ９の延長方向に連なるように設けられている。かかる第１補強部材１０は、閉断面構造の角材とされており、それ自体の剛性が高められている。   The first reinforcing member 10 is disposed on both sides in the vehicle width direction of the second mounting portion 7 in the vehicle front-rear direction, and is provided so as to continue in the extending direction of the rear side member 9. The first reinforcing member 10 is a square member having a closed cross-sectional structure, and its own rigidity is enhanced.

第２補強部材１１は、図８に示すように、幾つかの骨組１１ａによって三角形状を構成するトラス構造とされている。また、第２補強部材１１は、リヤサスペンション５と干渉しないように、その断面を車両上方から下方に向けて小さくしている。かかる第２補強部材１１は、前記した仕切り壁部８の前面である段差面部に設けられ、その車幅方向両端を各リヤサイドメンバ９の先端部に結合させている。   As shown in FIG. 8, the second reinforcing member 11 has a truss structure in which a triangular shape is formed by several frames 11a. Further, the second reinforcing member 11 has a cross section that is reduced from the upper side to the lower side so as not to interfere with the rear suspension 5. The second reinforcing member 11 is provided on the stepped surface portion that is the front surface of the partition wall portion 8, and both ends in the vehicle width direction are coupled to the front end portions of the rear side members 9.

ケース３は、第１搭載部６及び第２搭載部７にそれぞれ搭載されたバッテリー１を覆うようにして、前記バッテリー搭載トレイ２に取り付けられている。かかるケース３は、第１搭載部６を覆う第１ケース部３ａと、この第１ケース部３ａより高さが高く第２搭載部７を覆う第２ケース部３ｂと、を有している。第１ケース部３ａは、平板形状とされ、第２ケース部３ｂは、平面視矩形状をなす突起形状とされている。このケース３がバッテリー搭載トレイ２に取り付けられることで、バッテリー１を収容するバッテリー収容部が閉断面構造とされると共に、バッテリー１が外的要因から保護されることになる。   The case 3 is attached to the battery mounting tray 2 so as to cover the batteries 1 mounted on the first mounting portion 6 and the second mounting portion 7, respectively. The case 3 includes a first case portion 3 a that covers the first mounting portion 6, and a second case portion 3 b that is higher than the first case portion 3 a and covers the second mounting portion 7. The first case portion 3a has a flat plate shape, and the second case portion 3b has a protruding shape having a rectangular shape in plan view. By attaching the case 3 to the battery mounting tray 2, the battery accommodating portion that accommodates the battery 1 has a closed cross-sectional structure, and the battery 1 is protected from external factors.

そして、前記ケース３でバッテリー１を覆ったバッテリー搭載トレイ２は、互いの外周縁の結合部にシール部材１２を取り付け、このシール部材１２で車両用骨格フレーム４に密着され、ボルト及びナット等の締結手段によって前記車両用骨格フレーム４に固定されている。バッテリー搭載トレイ２と車両用骨格フレーム４との結合部位は、押し出し材からなるバッテリー搭載トレイ２と一体的に取り付けフランジとして設けられている（図示は省略する）。   The battery mounting tray 2 that covers the battery 1 with the case 3 is attached with a seal member 12 at a joint portion between the outer peripheral edges thereof, and is in close contact with the vehicle frame 4 with the seal member 12, such as bolts and nuts. It is fixed to the vehicle frame 4 by fastening means. A joint portion between the battery mounting tray 2 and the vehicle frame 4 is provided as a mounting flange integrally with the battery mounting tray 2 made of extruded material (not shown).

車両用骨格フレーム４には、ケース３でバッテリー１が覆われたバッテリー搭載トレイ２をすっぽりとその内部に収容させるバッテリー収容部１３が設けられている。このバッテリー収容部１３の外周縁部と前記シール部材１２とが密着して水密構造となっている。   The vehicle skeleton frame 4 is provided with a battery housing portion 13 for completely housing the battery mounting tray 2 in which the battery 1 is covered with the case 3. The outer peripheral edge of the battery housing 13 and the seal member 12 are in close contact with each other to form a watertight structure.

以上のように構成されたバッテリー搭載構造においては、例えば図７で示すように、車両後方から前方に向けて入力荷重Ｆ１があった場合、その入力荷重がリヤサイドメンバ９に伝達されると共に、このリヤサイドメンバ９に略沿って車両前後方向に配置された第１補強部材１０にも前記入力荷重が伝達される。つまり、後面衝突時には、入力荷重Ｆ１を、リヤサイドメンバ９と第１補強部材１０の両方で受け止めることができる。また、図７で示すように、車両側方から入力荷重Ｆ２があった場合、その入力荷重を箱断面構造とされたケース３及びバッテリー搭載トレイ２で受け止めると共に、更に車幅方向に設けられた第２補強部材１１で受け止めることができる。   In the battery mounting structure configured as described above, for example, as shown in FIG. 7, when there is an input load F1 from the rear to the front of the vehicle, the input load is transmitted to the rear side member 9, and this The input load is also transmitted to the first reinforcing member 10 disposed in the vehicle front-rear direction substantially along the rear side member 9. That is, at the time of a rear collision, the input load F1 can be received by both the rear side member 9 and the first reinforcing member 10. Further, as shown in FIG. 7, when there is an input load F2 from the side of the vehicle, the input load is received by the case 3 and the battery mounting tray 2 having a box cross-sectional structure, and further provided in the vehicle width direction. It can be received by the second reinforcing member 11.

本実施形態によれば、バッテリー搭載トレイ２を箱形状としたので、車両下方から跳ね上げられる飛び石や縁石に衝突する等の外的要件からその内部に搭載されるバッテリー１を保護することができる。また、本実施形態によれば、第１補強部材１０と第２補強部材１１をバッテリー搭載トレイ２に設けたことで、当該バッテリー搭載トレイ２自体の剛性を高めることができる。   According to this embodiment, since the battery mounting tray 2 has a box shape, it is possible to protect the battery 1 mounted therein from external requirements such as collision with a stepping stone or curb raised from below the vehicle. . Further, according to the present embodiment, the first reinforcing member 10 and the second reinforcing member 11 are provided in the battery mounting tray 2, whereby the rigidity of the battery mounting tray 2 itself can be increased.

また、本実施形態によれば、第１補強部材１０と第２補強部材１１をバッテリー搭載トレイ２に設けると共に、その第１補強部材１０の前端同士を車幅方向に連結するように第２補強部材１１を設けたので、後面衝突荷重を第１補強部材１０に伝達させることができ、また、側面衝突荷重を第２補強部材１１に伝達させることができる。さらには、リヤサイドメンバ９の変形時に、このバッテリー搭載トレイ２の車両用骨格フレーム４への締結点を通して荷重を広範囲に伝達させることが可能となる。   Moreover, according to this embodiment, while providing the 1st reinforcement member 10 and the 2nd reinforcement member 11 in the battery mounting tray 2, it is 2nd reinforcement so that the front ends of the 1st reinforcement member 10 may be connected to a vehicle width direction. Since the member 11 is provided, the rear collision load can be transmitted to the first reinforcing member 10, and the side collision load can be transmitted to the second reinforcing member 11. Furthermore, when the rear side member 9 is deformed, the load can be transmitted over a wide range through the fastening point of the battery-mounted tray 2 to the vehicle frame 4.

また、本実施形態によれば、バッテリー１を搭載する部位を、フロア下の第１搭載部６とリヤサスペンション５上の第２搭載部７の２箇所に設けたので、バッテリー容量を大幅に増やすことができ、電気自動車に求められる航続距離を充分に確保することが可能となる。   Further, according to the present embodiment, the battery 1 is mounted at two locations, the first mounting portion 6 below the floor and the second mounting portion 7 on the rear suspension 5, so that the battery capacity is greatly increased. Therefore, it is possible to sufficiently secure the cruising distance required for the electric vehicle.

また、本実施形態によれば、バッテリー搭載トレイ２の開口側の最外周フランジ部１２をシール面として、バッテリー１を覆うケース３を取り付けてバッテリー収容部を閉断面構造としたので、ケース３でバッテリー１を保護できると共にバッテリー搭載トレイ２の剛性を更に高めることができる。さらには、第１搭載部６と第２搭載部７の結合部位の剛性が高まり、第２搭載部７のシール性を安定させることができる。これにより、バッテリー搭載トレイ２内に水等の侵入を防止することが可能となる。   Further, according to the present embodiment, since the outermost peripheral flange portion 12 on the opening side of the battery mounting tray 2 is used as a sealing surface, the case 3 that covers the battery 1 is attached and the battery housing portion has a closed cross-sectional structure. The battery 1 can be protected and the rigidity of the battery mounting tray 2 can be further increased. Furthermore, the rigidity of the joint portion between the first mounting portion 6 and the second mounting portion 7 is increased, and the sealing performance of the second mounting portion 7 can be stabilized. Thereby, it is possible to prevent water and the like from entering the battery mounting tray 2.

また、本実施形態によれば、第２補強部材１１を、第１搭載部６と第２搭載部７を仕切る車両高さ方向に起立する段差面部に設けたので、この第２補強部材１１によってバッテリー搭載トレイ２の剛性が高まる。   Moreover, according to this embodiment, since the 2nd reinforcement member 11 was provided in the level | step difference surface part which stands in the vehicle height direction which partitions off the 1st mounting part 6 and the 2nd mounting part 7, this 2nd reinforcement member 11 The rigidity of the battery mounting tray 2 is increased.

また、本実施形態によれば、第２補強部材１１の形状をトラス構造としたので、第１搭載部６と第２搭載部７の境界部の剛性が高まり、大容量バッテリーの重量に耐え得ることができる共に側面衝突時の入力荷重にも耐え得る。   Moreover, according to this embodiment, since the shape of the 2nd reinforcement member 11 was made into the truss structure, the rigidity of the boundary part of the 1st mounting part 6 and the 2nd mounting part 7 increases, and can endure the weight of a large capacity battery. It can withstand the input load at the time of side collision.

また、本実施形態によれば、第２補強部材１１の断面を車両上方から下方に向けて小さくしたので、リヤサスペンション５を車両用骨格フレーム４に取り付ける搭載スペースを確保することができると共にリヤサスペンション５との干渉を無くすことができる。   In addition, according to the present embodiment, since the cross section of the second reinforcing member 11 is reduced from the upper side to the lower side of the vehicle, a mounting space for attaching the rear suspension 5 to the vehicle frame 4 can be secured and the rear suspension. 5 can be eliminated.

また、本実施形態によれば、バッテリー搭載トレイ２を押し出し材で形成したので、トレイ自体の剛性を高めることができる。   In addition, according to the present embodiment, since the battery-mounted tray 2 is formed of an extruded material, the rigidity of the tray itself can be increased.
