Description

本発明は、車両に搭載されるバッテリを固定する構造に関する。 The present invention relates to a structure for fixing a battery mounted on a vehicle.

従来、自動車のエンジンルーム内にバッテリを収納することがなされている(例、特許文献1,2)。特許文献1は、多数のブラケットを介して、バッテリが載置される平板状の台座部と、ミッションマウントやフロントサイドメンバ(フレーム)とをボルト締結する構造を開示する。上記台座部は、ブラケットの上面に締結されて、車両上下方向の上方からミッションマウントを覆うように配置される(特許文献1の図3)。特許文献2は、パワープラントのマウント部材を取り付けるためのブラケット(取付部)の上面に、平板状の台座部(バッテリベース)を取り付ける構造を開示する(第4図)。 BACKGROUND ART Conventionally, batteries have been stored in the engine room of automobiles (eg, Patent Documents 1 and 2). Patent Document 1 discloses a structure in which a flat plate-shaped pedestal on which a battery is mounted and a mission mount or a front side member (frame) are bolted through a plurality of brackets. The pedestal portion is fastened to the upper surface of the bracket and is arranged so as to cover the mission mount from above in the vehicle vertical direction (FIG. 3 of Patent Document 1). Patent Document 2 discloses a structure in which a flat pedestal portion (battery base) is mounted on the upper surface of a bracket (mounting portion) for mounting a mount member of a power plant (FIG. 4).

特開2017−154549号公報JP, 2017-154549, A 実開平03−123784号公報Japanese Utility Model Publication No. 03-123784

重量物であるバッテリを載置するためには、バッテリが載置される台座部の剛性を大きく確保する必要がある。特許文献1に記載されるように、ブラケットの個数を多くし、更に台座部をブラケットの上面で支持すれば、平板状の台座部が撓むことを抑制し易い。従って、マウント部材等に締結された状態における台座部は、剛性を高められる。しかし、この場合、部品点数が多い。 In order to mount the battery, which is a heavy object, it is necessary to secure a large rigidity of the pedestal on which the battery is mounted. As described in Patent Document 1, if the number of brackets is increased and the pedestal part is supported by the upper surface of the bracket, it is easy to suppress the flat pedestal part from bending. Therefore, the pedestal portion in the state of being fastened to the mount member or the like can have increased rigidity. However, in this case, the number of parts is large.

また、バッテリが載置された状態において、バッテリにおける地表からの位置(以下、載置位置と呼ぶ)をできる限り低くすることが望まれる。特許文献1,2に記載されるようにブラケットの上面に台座部を取り付けると、バッテリの載置位置が高くなる。即ち、重心位置が高い。バッテリの重心位置が高いと、操縦安定性の悪化を招く。また、バッテリの載置位置が高いと、歩行者保護のためのクリアランスをエンジンルーム内に十分に確保することが難しくなる。 In addition, it is desired that the position of the battery from the ground surface (hereinafter, referred to as a mounting position) be as low as possible when the battery is mounted. When the pedestal portion is attached to the upper surface of the bracket as described in Patent Documents 1 and 2, the battery mounting position becomes high. That is, the center of gravity is high. If the position of the center of gravity of the battery is high, the steering stability is deteriorated. Further, when the battery mounting position is high, it becomes difficult to secure a sufficient clearance for protecting a pedestrian in the engine room.

そこで、本発明の目的の一つは、バッテリを載置する台座部の剛性を確保しつつ、バッテリの載置位置を低くできる車両のバッテリ固定構造を提供することにある。 Therefore, one of the objects of the present invention is to provide a battery fixing structure for a vehicle that can lower the mounting position of the battery while ensuring the rigidity of the pedestal part on which the battery is mounted.

The pedestal part is
A mounting surface of the battery,
A box portion that protrudes above the mounting surface in the vehicle vertical direction and that is provided so as to surround at least a part of a mount member that fixes the power unit,
A fastening portion provided on the upper surface of the box portion and fastened to the mount member.

上記の車両のバッテリ固定構造では、台座部がボックス部を有するという立体形状であるため、台座部自体の剛性が高い。また、上記の車両のバッテリ固定構造は、ボックス部内にマウント部材の一部が挿入された状態で締結される。これらのことから、上記の車両のバッテリ固定構造は、マウント部材等に締結された状態における台座部の剛性を良好に確保できる。 In the vehicle battery fixing structure described above, the pedestal portion has a three-dimensional shape having a box portion, and therefore the pedestal portion itself has high rigidity. The battery fixing structure for a vehicle is fastened with a part of the mount member inserted in the box portion. For these reasons, the vehicle battery fixing structure described above can favorably secure the rigidity of the pedestal portion when it is fastened to the mount member or the like.

また、上記の車両のバッテリ固定構造では、台座部におけるバッテリの載置面がマウント部材との締結部よりも車両上下方向の下方に位置する。このような台座部に支持されるバッテリは、載置位置を低くできる。従って、上記の車両のバッテリ固定構造は、バッテリの重心位置を低くできるため、操縦安定性に優れる。また、バッテリの載置位置が低いことで、保護者保護のためのクリアランスをエンジンルーム内に確保できる。 Further, in the above-described vehicle battery fixing structure, the battery mounting surface of the pedestal portion is located below the fastening portion with the mount member in the vehicle vertical direction. The mounting position of the battery supported by such a pedestal can be lowered. Therefore, the battery fixing structure for a vehicle described above can lower the center of gravity of the battery, and thus is excellent in steering stability. Further, since the battery mounting position is low, a clearance for protecting the guardian can be secured in the engine room.

[実施形態1]
(概要)
実施形態1に係る車両のバッテリ固定構造1は、代表的には自動車の車体11の前方に設けられるエンジンルーム10に構築されて、車載電装品に電力供給を行うバッテリ40(代表的には直方体状)を車体11に固定することに利用される。図1は、バッテリ40及びバッテリトレー4を二点鎖線で仮想的に示す。
[Embodiment 1]
(Overview)
The vehicle battery fixing structure 1 according to the first embodiment is typically constructed in an engine room 10 provided in front of a vehicle body 11 of an automobile to supply electric power to vehicle-mounted electrical components (typically a rectangular parallelepiped). Shape) is used for fixing to the vehicle body 11. FIG. 1 virtually shows the battery 40 and the battery tray 4 by a chain double-dashed line.

車両のバッテリ固定構造1は、バッテリ40が載置される台座部2を備える。台座部2は、エンジンルーム10に収納されるパワーユニット100を車体11に取り付けるマウント部材5に固定される。台座部2は、マウント部材5を介して、車体11に固定される。代表的には、台座部2上にバッテリトレー4が配置される。バッテリトレー4上にバッテリ40が載置される。台座部2は、バッテリトレー4を介して、バッテリ40をその底面から支持する。台座部2には、バッテリ40を囲むように配置される門型の拘束部3が取り付けられる。バッテリ40は、台座部2と拘束部3とによって支持される。 The vehicle battery fixing structure 1 includes a pedestal portion 2 on which the battery 40 is placed. The pedestal portion 2 is fixed to a mount member 5 for mounting the power unit 100 housed in the engine room 10 on the vehicle body 11. The pedestal portion 2 is fixed to the vehicle body 11 via the mount member 5. Typically, the battery tray 4 is arranged on the pedestal portion 2. The battery 40 is placed on the battery tray 4. The pedestal portion 2 supports the battery 40 from its bottom surface via the battery tray 4. A gate-shaped restraint portion 3 arranged so as to surround the battery 40 is attached to the pedestal portion 2. The battery 40 is supported by the pedestal portion 2 and the restraint portion 3.

特に、実施形態1の車両のバッテリ固定構造1では、台座部2は、平板状ではなく、立体的な形状である(図2も参照)。台座部2は、バッテリ40を支持する面(後述の載置面20f)よりも車両上下方向の上方に突出する部分(後述のボックス部21)を備える。更に、台座部2は、図2に示すようにボックス部21にマウント部材5との固定箇所(後述の締結部25)を備える。締結部25の位置は、載置面20fよりも上方に位置する(図3)。つまり、載置面20fは、締結部25の位置よりも下方に位置する。そのため、載置面20fに支持されるバッテリ40の載置位置は、締結部25の位置で支持される場合に比較して、低くなる。 Particularly, in the vehicle battery fixing structure 1 of the first embodiment, the pedestal portion 2 is not a flat plate shape but a three-dimensional shape (see also FIG. 2 ). The pedestal portion 2 includes a portion (a box portion 21 described below) that protrudes upward in the vehicle vertical direction from a surface (a mounting surface 20f described below) that supports the battery 40. Further, as shown in FIG. 2, the pedestal portion 2 is provided with a fixing portion (a fastening portion 25 to be described later) fixed to the mount member 5 on the box portion 21. The position of the fastening portion 25 is located above the mounting surface 20f (FIG. 3). That is, the mounting surface 20f is located below the position of the fastening portion 25. Therefore, the mounting position of the battery 40 supported by the mounting surface 20f becomes lower than that in the case where the battery 40 is supported at the position of the fastening portion 25.

以下、まず、バッテリ40を載置する箇所の周囲の構造を簡単に説明する。次に、台座部2を詳細に説明する。 Hereinafter, first, the structure around the portion where the battery 40 is placed will be briefly described. Next, the pedestal portion 2 will be described in detail.

(周囲の構造)
図1は、車体11の前部のうち、バッテリ40を載置する左方の領域のみを例示する。
車体11は、サイドメンバ12、モーメントキャンセラ13、ストラットタワー14等を備える。車幅方向に離間して設けられるサイドメンバ12間(図1では左側のサイドメンバ12のみ図示)にパワーユニット100が配置される。パワーユニット100は、マウント部材5を介して、車体11(ここではサイドメンバ12、モーメントキャンセラ13)に支持される。本例のパワーユニット100は、エンジン(図示せず)と、エンジンの一端に固定されるトランスミッション101とを備える。
(The surrounding structure)
FIG. 1 illustrates only a left region of the front portion of the vehicle body 11 on which the battery 40 is mounted.
The vehicle body 11 includes a side member 12, a moment canceller 13, a strut tower 14, and the like. The power unit 100 is arranged between the side members 12 provided apart from each other in the vehicle width direction (only the left side member 12 is shown in FIG. 1). The power unit 100 is supported by the vehicle body 11 (here, the side member 12, the moment canceller 13) via the mount member 5. The power unit 100 of this example includes an engine (not shown) and a transmission 101 fixed to one end of the engine.

マウント部材5は、ゴムブッシュ(図示せず)といった弾性体を備える。マウント部材5は、この弾性体によってエンジンの振動を吸収する。本例では、マウント部材5の一方の端部51がパワーユニット100(ここではトランスミッション101)に締結される。マウント部材5の他方の端部52が車体11(ここではモーメントキャンセラ13)に締結される。このマウント部材5は、図3に示すように、下方に位置する端部51から、上方に位置する端部52に向かって延びるような部材であり、その長手方向の中間部に円筒部53を備える(図4も参照)。円筒部53にはゴムブッシュが嵌め込まれる。ここでは、円筒部53の軸方向が車幅方向に沿うように円筒部53が設けられているが、円筒部53の向きは適宜変更できる。 The mount member 5 includes an elastic body such as a rubber bush (not shown). The mount member 5 absorbs the vibration of the engine by this elastic body. In this example, one end 51 of the mount member 5 is fastened to the power unit 100 (here, the transmission 101). The other end 52 of the mount member 5 is fastened to the vehicle body 11 (here, the moment canceller 13). As shown in FIG. 3, the mount member 5 is a member that extends from an end portion 51 located below to an end portion 52 located above, and a cylindrical portion 53 is provided at an intermediate portion in the longitudinal direction thereof. Prepare (see also FIG. 4). A rubber bush is fitted into the cylindrical portion 53. Here, the cylindrical portion 53 is provided so that the axial direction of the cylindrical portion 53 extends along the vehicle width direction, but the orientation of the cylindrical portion 53 can be changed as appropriate.

なお、図3は、台座部2及びマウント部材5を円筒部53の軸方向(ここでは概ね車幅方向)に平行な平面で切断した断面図である。図4は、台座部2及びマウント部材5を円筒部53の軸方向に直交する平面(円筒部53の径方向に平行な縦平面)で切断した断面図である。 3 is a cross-sectional view of the pedestal portion 2 and the mount member 5 taken along a plane parallel to the axial direction of the cylindrical portion 53 (here, generally in the vehicle width direction). FIG. 4 is a cross-sectional view of the pedestal portion 2 and the mount member 5 taken along a plane orthogonal to the axial direction of the cylindrical portion 53 (a vertical plane parallel to the radial direction of the cylindrical portion 53).

更に、本例のマウント部材5は、円筒部53の外周面のうち、上方に位置する領域に固定台54を備える(図2〜図4)。固定台54は、対向配置される二つの側壁部と、両側壁部を繋ぐ上面部とを備える断面門型である(図4)。固定台54の上面部は、側壁部よりも長く、車体11側に向かって延びている(図3)。上面部の端部は、締結部材7(例、ボルト及びナット)によって車体11に締結される端部52をなす(図2,図3)。固定台54において、円筒部53の上方に位置する箇所の一部が台座部2との締結箇所として利用される(図3,図4)。固定台54における台座部2との締結箇所は、固定台54の他の箇所よりも上方に向かって局所的に高くなっている(図3)。 Further, the mount member 5 of the present example is provided with the fixing base 54 in an upper region of the outer peripheral surface of the cylindrical portion 53 (FIGS. 2 to 4). The fixed base 54 has a cross-section gate type including two side wall portions arranged opposite to each other and an upper surface portion connecting both side wall portions (FIG. 4 ). The upper surface portion of the fixed base 54 is longer than the side wall portion and extends toward the vehicle body 11 side (FIG. 3 ). The end portion of the upper surface portion forms an end portion 52 that is fastened to the vehicle body 11 by the fastening member 7 (eg, bolt and nut) (FIGS. 2 and 3). In the fixed base 54, a part of the portion located above the cylindrical portion 53 is used as a fastening portion with the pedestal portion 2 (FIGS. 3 and 4). The fastening portion of the fixed base 54 with the pedestal portion 2 is locally higher than the other portions of the fixed base 54 (FIG. 3).

The body portion 20 and the box portion 21 are integrally joined by welding or the like.

〈本体部〉
主に、図5を参照して、本体部20を説明する。
本例の本体部20は、上方からの平面視で台形状である。この本体部20におけるバッテリトレー4(バッテリ40)が配置される領域の面積(図5ではバッテリトレー4と重複する箇所の面積)は、バッテリトレー4の面積よりも小さい。この点で、本体部20は軽量である。
<Main body>
The main body 20 will be described mainly with reference to FIG.
The main body 20 of this example has a trapezoidal shape in a plan view from above. The area of the area where the battery tray 4 (battery 40) is arranged in the main body portion 20 (the area of the portion overlapping the battery tray 4 in FIG. 5) is smaller than the area of the battery tray 4. In this respect, the main body 20 is lightweight.

本例の本体部20は、車体11側の縁(図5では下端縁)の一部が開口する矩形状の切欠を有する。切欠の周縁は、車幅方向(図5では紙面上下方向)に延びる二つの直線状の縁と、車両前後方向(図5では紙面左右方向)に延びる一つの直線状の縁とを備える門型である。本体部20は、切欠の周縁から上方に突出する側壁部200を有する(図2,図4)。側壁部200は、ボックス部21との接合箇所に利用される。 The main body 20 of this example has a rectangular notch in which a part of the edge (lower edge in FIG. 5) on the vehicle body 11 side is open. The peripheral edge of the notch has two linear edges extending in the vehicle width direction (vertical direction on the paper surface in FIG. 5) and one linear edge extending in the vehicle front-rear direction (horizontal direction on the paper surface in FIG. 5). Is. The main body portion 20 has a side wall portion 200 protruding upward from the peripheral edge of the cutout (FIGS. 2 and 4). The side wall portion 200 is used as a joint portion with the box portion 21.

更に、本例の本体部20は、平坦な平板状ではなく屈曲形状であり、切欠が設けられた箇所よりも下方に向かって凹む部分を備える。詳しくは、本体部20は、切欠を設けた箇所を含む中央部に舌状の領域(以下、中央領域201と呼ぶ)を備える。また、本体部20は、本体部20の周縁のうち、車体11側の箇所を除く箇所に沿った帯状の領域(以下、外周領域202と呼ぶ)を備える。中央領域201の表面と外周領域202の表面とは面一である(図3)。中央領域201の表面と、外周領域202の表面の少なくとも一部(図5ではバッテリトレー4と重複する箇所)とが載置面20fに利用される。 Further, the main body portion 20 of this example is not a flat plate shape but a bent shape, and includes a portion that is recessed downward from a place where the cutout is provided. Specifically, the main body portion 20 includes a tongue-shaped region (hereinafter, referred to as a central region 201) in a central portion including a cutout portion. Further, the main body portion 20 includes a band-shaped region (hereinafter, referred to as an outer peripheral region 202) along a portion of the peripheral edge of the main body portion 20 excluding a portion on the vehicle body 11 side. The surface of the central area 201 and the surface of the outer peripheral area 202 are flush with each other (FIG. 3).

[作用効果]
実施形態1の車両のバッテリ固定構造1は、以下の理由により、マウント部材5等に締結された状態における台座部2の剛性を確保しつつ、バッテリ40の載置位置を低くできる。
[Effect]
The battery fixing structure 1 for a vehicle of the first embodiment can lower the mounting position of the battery 40 while ensuring the rigidity of the pedestal portion 2 in the state of being fastened to the mount member 5 and the like for the following reasons.

(剛性について)
(1)台座部2の形状が、バッテリ40の載置面20fよりも上方に張り出すボックス部21を備えるという立体的な形状であり、台座部2自体の剛性に優れる。
(About rigidity)
(1) The pedestal portion 2 has a three-dimensional shape including the box portion 21 protruding above the mounting surface 20f of the battery 40, and the pedestal portion 2 itself has excellent rigidity.

(2)本例の台座部2は、以下の点からも台座部2自体の剛性に優れる。
・本体部20が凹部203を有して立体的な形状である。
・ボックス部21は、複数の部材が重ね合わされて接合された組物であるため、ボックス部21自体の剛性に優れる。
・ボックス部21は、第二の囲み部23の上面部234と連結部24とが互いに離間して配置された二段のボックス形状である。この点から、ボックス部21は、剛性により優れる。
・第一の囲み部22は、門型状であると共に連結部24が接合されるため、第一の囲み部22自体の剛性に優れる。
・第二の囲み部23の上面部234が凹凸形状であるため、第二の囲み部23自体の剛性に優れる。
(2) The pedestal portion 2 of this example is also excellent in rigidity of the pedestal portion 2 itself from the following points.
The main body 20 has a recess 203 and has a three-dimensional shape.
Since the box portion 21 is a braid in which a plurality of members are stacked and joined together, the box portion 21 itself has excellent rigidity.
The box portion 21 has a two-step box shape in which the upper surface portion 234 of the second surrounding portion 23 and the connecting portion 24 are arranged so as to be separated from each other. From this point, the box portion 21 is superior in rigidity.
Since the first enclosing portion 22 has a gate shape and the connecting portion 24 is joined, the rigidity of the first enclosing portion 22 itself is excellent.
Since the upper surface portion 234 of the second surrounding portion 23 has an uneven shape, the rigidity of the second surrounding portion 23 itself is excellent.

(3)剛性に優れるボックス部21が、マウント部材5との締結部25を備えると共に、ボックス部21内にマウント部材5の一部が挿入された状態で、ボックス部21とマウント部材5とが締結される。このような締結構造は、平板状の台座部とブラケットの平坦な上面とが重ね合わされてボルト締結された場合に比較して、マウント部材5等に締結された状態における台座部2の剛性の向上に寄与する。本例の台座部2は、ブラケットを介して車体11に固定されており、マウント部材5及び車体11に対して複数の締結箇所を有することからも、上記剛性を高められる。 (3) The box portion 21 having excellent rigidity includes the fastening portion 25 with the mount member 5, and the box portion 21 and the mount member 5 are separated from each other with the mount member 5 partially inserted in the box portion 21. It is concluded. In such a fastening structure, the rigidity of the pedestal portion 2 in the state of being fastened to the mount member 5 and the like is improved as compared with the case where the flat pedestal portion and the flat upper surface of the bracket are overlapped and bolted. Contribute to. The pedestal portion 2 of the present example is fixed to the vehicle body 11 via a bracket and has a plurality of fastening points with respect to the mount member 5 and the vehicle body 11. Therefore, the rigidity can be increased.

(載置位置について)
台座部2におけるバッテリ40の載置面20fは、マウント部材5との締結部25よりも下方に位置する。そのため、台座部2に支持されるバッテリ40の載置位置は、マウント部材に取り付けられたブラケットの上面に締結された台座部に支持される場合に比較して、低くなる。このような実施形態1の車両のバッテリ固定構造1は、バッテリ40の重心位置を低くできるため、操縦安定性の向上に寄与する。また、バッテリ40の載置位置を低くできることで、エンジンルーム10内に保護者保護のためのクリアランス、例えば車両の上方からエンジンルーム10側に向って歩行者の頭部が突入する場合に対応するためのクリアランス等を確保できる。
(About mounting position)
The mounting surface 20f of the battery 40 in the pedestal portion 2 is located below the fastening portion 25 with the mount member 5. Therefore, the mounting position of the battery 40 supported by the pedestal portion 2 becomes lower than that when the battery 40 is supported by the pedestal portion fastened to the upper surface of the bracket attached to the mount member. In the vehicle battery fixing structure 1 of the first embodiment as described above, since the position of the center of gravity of the battery 40 can be lowered, it contributes to the improvement of steering stability. Further, since the mounting position of the battery 40 can be lowered, it is possible to cope with a clearance for protecting a guardian in the engine room 10, for example, a case where the head of a pedestrian projects from above the vehicle toward the engine room 10 side. It is possible to secure clearance for

更に、本例の車両のバッテリ固定構造1は、以下の効果を奏する。
(a)マウント部材5の周囲に形成されるデッドスペースを有効に活用することができる。詳しくは、図1に示すように、台座部2のうち本体部20は、締結部25(図3)に比較して、マウント部材5に近くづくように配置される。特に、本体部20の凹部203は、中央領域201及び外周領域202に比較して、マウント部材5に近づくように配置される。このような台座部2は、マウント部材5との間に形成される隙間を小さくできるため、マウント部材5の周囲の空間を有効に利用しているといえる。
(b)ブラケットといった部品を少なくすることができる。
(c)台座部2は、本体部20の一部に切欠を有して、車両上下方向に貫通する箇所を有するものの、切欠はボックス部21(特に第二の囲み部23)によって上方から塞がれる。そのため、切欠の下方に位置するマウント部材5の一部は、ボックス部21によって覆われる。このようなボックス部21によって、異物がゴムブッシュ等の弾性体側に入り込むことを低減できる。
Further, the vehicle battery fixing structure 1 of this example has the following effects.
(A) The dead space formed around the mount member 5 can be effectively utilized. Specifically, as shown in FIG. 1, the main body portion 20 of the pedestal portion 2 is arranged closer to the mount member 5 than the fastening portion 25 (FIG. 3). In particular, the recess 203 of the main body 20 is arranged so as to be closer to the mount member 5 than the central region 201 and the outer peripheral region 202. Since such a pedestal portion 2 can reduce the gap formed between the pedestal portion 2 and the mount member 5, it can be said that the space around the mount member 5 is effectively used.
(B) The number of parts such as brackets can be reduced.
(C) The pedestal part 2 has a notch in a part of the main body part 20 and has a portion penetrating in the vehicle vertical direction, but the notch is closed from above by the box part 21 (particularly the second enclosing part 23). Get off. Therefore, a part of the mount member 5 located below the cutout is covered by the box portion 21. By such a box portion 21, it is possible to reduce foreign matter from entering the elastic body side such as a rubber bush.
