Description

本発明は、車両用バッテリー保持構造に関する。 The present invention relates to a vehicle battery holding structure.

車両には、エンジン始動時のスターターへの電力供給や電装品への電力供給などに用いるバッテリーが搭載されており、該バッテリーは、規格によってサイズや形状がほぼ決まっている。このようなバッテリーを車両に搭載する場合は、車体側に取付けたバッテリートレイにバッテリーを載せ、バッテリーの前面下部の突起部の中央付近をバッテリーバンドで押し付けて挟持し、バッテリーの後面下部の突起部の中央付近をバッテリートレイに設けられた係止部で押し付けて挟持することにより、バッテリーがバッテリートレイに保持されるようになっている（例えば、特許文献１参照）。 The vehicle is equipped with a battery used for supplying electric power to the starter and electrical components when the engine is started, and the size and shape of the battery are almost determined by the standard. When mounting such a battery in a vehicle, place the battery on the battery tray attached to the vehicle body side, press the center of the protrusion on the lower front surface of the battery with a battery band to hold it, and hold the protrusion on the lower rear surface of the battery. The battery is held in the battery tray by pressing and sandwiching the vicinity of the center of the battery tray with a locking portion provided on the battery tray (see, for example, Patent Document 1).

しかしながら、上述した従来の車両用バッテリー保持構造は、バッテリーの前面下部及び後面下部の突起部をバッテリーバンド及び係止部で挟持することにより、バッテリートレイに載せたバッテリーを車両前後方向から保持しているに過ぎないので、車体に発生する振動や後突時などの慣性力によりバッテリーが浮き上がったり、あるいは、バッテリーが車両前後方向に移動したりして、突起部とバッテリーバンド及び係止部との保持部分からずれてしまい、バッテリーがバッテリートレイから外れてしまうおそれがあった。
また、上述した従来の車両用バッテリー保持構造は、走行時の車両幅方向の動きに対してバッテリーの動きを抑制することができないので、バッテリーがバッテリーバンドの保持から外れて車両幅方向に動き、バッテリーがバッテリーバンドにより削られてしまうという懸念を有していた。 However, in the conventional vehicle battery holding structure described above, the battery mounted on the battery tray is held from the front and rear direction of the vehicle by sandwiching the protrusions on the lower front surface and the lower rear surface of the battery between the battery band and the locking portion. The battery floats due to the vibration generated in the vehicle body or the inertial force at the time of a rear collision, or the battery moves in the front-rear direction of the vehicle, so that the protrusion and the battery band and the locking portion are connected to each other. There was a risk that the battery would slip off the holding part and come off the battery tray.
Further, since the conventional battery holding structure for a vehicle described above cannot suppress the movement of the battery with respect to the movement in the vehicle width direction during traveling, the battery moves out of the holding of the battery band and moves in the vehicle width direction. There was concern that the battery would be scraped by the battery band.

本発明はこのような実状に鑑みてなされたものであって、その目的は、車体に発生する振動や衝突時の慣性力によりバッテリーが車両幅方向及び車両前後方向へ動くことを同時に抑制して、バッテリーが保持部から外れることを防止し、バッテリーをバッテリートレイに安定して保持することが可能な車両用バッテリー保持構造を提供することにある。 The present invention has been made in view of such an actual situation, and an object of the present invention is to simultaneously suppress the movement of the battery in the vehicle width direction and the vehicle front-rear direction due to vibration generated in the vehicle body and inertial force at the time of collision. It is an object of the present invention to provide a vehicle battery holding structure capable of preventing the battery from coming off the holding portion and stably holding the battery in the battery tray.

上記従来技術の有する課題を解決するために、本発明は、車両に搭載されるバッテリーと、前記バッテリーを載せて車体側に取付けられるバッテリートレイと、前記バッテリートレイに取付けられるバッテリー保持部材と、を備え、前記バッテリーは、前記バッテリーの前面下部に設けられた前面側突起形状部と、前記バッテリーの側面下部に設けられた側面側突起形状部と、前記バッテリーの後面下部に設けられた後面側突起形状部と、を有し、前記バッテリー保持部材は、前記前面側突起形状部を保持し、前記バッテリーの前面に沿って延びる前面保持部と、前記側面側突起形状部を保持し、前記バッテリーの側面に沿って延びる側面保持部と、を有し、前記後面側突起形状部が前記バッテリートレイに支持される車両用バッテリー保持構造において、前記側面側突起形状部及び前記側面保持部は、前記バッテリーの左右両側面に配置されている。 In order to solve the problems of the prior art, the present invention comprises a battery mounted on a vehicle, a battery tray on which the battery is mounted and mounted on the vehicle body side, and a battery holding member mounted on the battery tray. The battery is provided with a front side protrusion shape portion provided on the lower front surface of the battery, a side protrusion shape portion provided on the lower side surface of the battery, and a rear surface side protrusion provided on the lower rear surface of the battery. The battery holding member has a shape portion, and holds the front surface side protrusion shape portion, and holds the front surface holding portion extending along the front surface of the battery and the side surface side protrusion shape portion of the battery. has a lateral supports extending along the side surface, and a vehicle battery holding structure the rear side projected part is Ru is supported on the battery tray, said side-side projected part and the lateral supports, the battery It is placed on both the left and right sides of .

上述の如く、本発明に係る車両用バッテリー保持構造は、車両に搭載されるバッテリーと、前記バッテリーを載せて車体側に取付けられるバッテリートレイと、前記バッテリートレイに取付けられるバッテリー保持部材と、を備え、前記バッテリーは、前記バッテリーの前面下部に設けられた前面側突起形状部と、前記バッテリーの側面下部に設けられた側面側突起形状部と、前記バッテリーの後面下部に設けられた後面側突起形状部と、を有し、前記バッテリー保持部材は、前記前面側突起形状部を保持し、前記バッテリーの前面に沿って延びる前面保持部と、前記側面側突起形状部を保持し、前記バッテリーの側面に沿って延びる側面保持部と、を有し、前記後面側突起形状部が前記バッテリートレイに支持される車両用バッテリー保持構造において、前記側面側突起形状部及び前記側面保持部は、前記バッテリーの左右両側面に配置されている。
したがって、本発明の車両用バッテリー保持構造においては、車両走行中の車体に発生する振動や後突時の衝撃による慣性力で車両前後方向に移動しようとするバッテリーの前面側突起形状部及び側面側突起形状部とバッテリー保持部材の前面保持部及び側面保持部とが外れにくくなっているので、バッテリーがバッテリートレイから外れてしまう不具合を防止することができ、バッテリーをバッテリートレイに長期間にわたり安定して保持することができる。 As described above, the vehicle battery holding structure according to the present invention includes a battery mounted on the vehicle, a battery tray on which the battery is mounted and mounted on the vehicle body side, and a battery holding member mounted on the battery tray. The battery has a front side protrusion shape portion provided on the lower front surface of the battery, a side protrusion shape portion provided on the lower side surface of the battery, and a rear surface side protrusion shape portion provided on the lower rear surface of the battery. The battery holding member holds the front surface side protrusion shape portion, holds the front surface holding portion extending along the front surface of the battery, and holds the side surface side protrusion shape portion, and holds the side surface of the battery. anda lateral supports extending along the, in the vehicle battery holding structure the rear side projected part is Ru is supported on the battery tray, said side-side projected part and said side holding portion of the battery It is placed on both the left and right sides .
Therefore, in the vehicle battery holding structure of the present invention, the front side protrusion shape portion and the side surface side of the battery that try to move in the front-rear direction of the vehicle due to the inertial force due to the vibration generated in the vehicle body while the vehicle is running and the impact at the time of rear collision. Since the protruding shape and the front and side holding parts of the battery holding member are hard to come off, it is possible to prevent the battery from coming off the battery tray and stabilize the battery in the battery tray for a long period of time. Can be held.

また、本発明の車両用バッテリー保持構造では、後突時の衝撃荷重でバッテリーが後端部を中心に持ち上がり、車両後方に回転する動きを回転中心から遠い箇所であるバッテリーの前面部のみならず、側面部の車両前方側をバッテリー保持部材の保持部で押え付けているので、バッテリーの車両後方回転の動きを効果的に抑制することが可能となり、バッテリーとバッテリー保持部材とをより一層外れにくくすることができ、バッテリーがバッテリートレイから外れてしまうという不具合の発生を低減させることができる。しかも、バッテリー保持部材によってバッテリーが側面部まで保持されているので、車両走行時の車両幅方向への動きに対してもバッテリーの同方向への動きを規制し、バッテリー保持部材によるバッテリーの削りを回避することができるとともに、バッテリー保持部材の保持がバッテリーから車両幅方向に外れることを確実に防止することができる。 Further, in the vehicle battery holding structure of the present invention, the battery is lifted around the rear end portion by the impact load at the time of rear collision, and the movement of rotating backward of the vehicle is not limited to the front portion of the battery which is a portion far from the rotation center. Since the front side of the vehicle is pressed by the holding part of the battery holding member, it is possible to effectively suppress the movement of the battery rotating backward in the vehicle, and the battery and the battery holding member are more difficult to come off. This can reduce the occurrence of problems such as the battery coming off the battery tray. Moreover, since the battery is held up to the side surface by the battery holding member, the movement of the battery in the same direction is restricted even when the vehicle is running in the vehicle width direction, and the battery holding member can scrape the battery. It can be avoided, and it is possible to surely prevent the holding of the battery holding member from coming off from the battery in the vehicle width direction.

It has a bottom surface portion 2a on which the battery 1 and the battery holding member 3 are installed, and a side surface portion 2b extending upward from the peripheral edge of the bottom surface portion 2a. The battery 1 is arranged on the rear side of the installation position of the battery holding member 3, and is held in a state of being placed on the bottom surface portion 2a of the battery tray 2 via the resin battery tray 6. Therefore, the resin battery tray 6 is formed by the length in the vehicle front-rear direction and the length in the vehicle width direction corresponding to the battery 1, and is upward from the bottom surface portion 6a on which the battery 1 is installed and the peripheral edge of the bottom surface portion 6a. It has an extending side surface portion 6b. Moreover, the resin battery tray 6 has a size such that the bottom surface portion 6a can come into contact with the lower end of the vertical wall portion described later of the protrusion-shaped portions 11, 12, 13 of the battery 1, and the side surface portion 6b is the battery 1. The protrusion-shaped portions 11, 12, and 13 have a size located outside the vertical wall portion described later.

本実施形態のバッテリー保持部材３は、図１〜図４及び図７に示すように、樹脂製バッテリートレイ６を介してバッテリートレイ２の底面部２ａに載せられたバッテリー１を保持するために、バッテリートレイ２の前方側に設けられている。そのため、バッテリー保持部材３は、バッテリートレイ２の底面部２ａに固定される本体部３１と、バッテリー１の前面下部１ａに沿って車両幅方向に延びる前面保持部３２と、バッテリー１の左右両側の側面下部１ｃに沿って車両前後方向に延びる側面保持部３３とを有している。そして、バッテリー１の前面側突起形状部１１は、バッテリー保持部材３の前面保持部３２によって保持され、バッテリー１の側面側突起形状部１３の車両前方側は、バッテリー保持部材３の側面保持部３３によって保持されるようになっている。 As shown in FIGS. 1 to 4 and 7, the battery holding member 3 of the present embodiment holds the battery 1 mounted on the bottom surface 2a of the battery tray 2 via the resin battery tray 6. It is provided on the front side of the battery tray 2. Therefore, the battery holding member 3 includes a main body 31 fixed to the bottom surface 2a of the battery tray 2, a front holding portion 32 extending in the vehicle width direction along the front lower portion 1a of the battery 1, and both left and right sides of the battery 1. It has a side surface holding portion 33 extending in the front-rear direction of the vehicle along the lower side surface 1c. The front projection shape portion 11 of the battery 1 is held by the front holding portion 32 of the battery holding member 3, and the vehicle front side of the side projection shape portion 13 of the battery 1 is the side holding portion 33 of the battery holding member 3. Is to be held by.

バッテリー保持部材３の本体部３１は、図１、図２及び図７に示すように、車両幅方向に間隔を空けて配置した２本の締付ボルト７を溶接ナット８に螺合させることにより、バッテリートレイ２の底面部２ａに離隔した状態で取付けられている。本体部３１を締付ボルト７で２点締結することにより、バッテリー保持部材３の動きを抑制し、バッテリー１が削れるのを防いでいる。また、本体部３１の前面保持部３２側（車両後方側）の端部は、バッテリー１の前面側突起形状部１１に近接する位置まで延び、本体部３１の車両前方側端部３１ｂは、バッテリートレイ２の車両前方側へ屈曲させた傾斜面状の側面部２ｂに当接する位置まで延び、該側面部２ｂに載置されており、本体部３１とバッテリートレイ２の底面部２ａとの上下間には、前面側突起形状部１１及び樹脂製バッテリートレイ６の側面部６ｂの配置スペースが形成されている。そのため、車両前方側端部３１ｂは、車両前方側へ屈曲させた傾斜面状の側面部２ｂとほぼ同角度に屈曲されている。これにより、バッテリー保持部材３とバッテリー１及びバッテリートレイ２との接触面積を増やして車両走行中のバッテリー１の動きがさらに抑制されるようになっている。
バッテリー保持部材３の本体部３１には、締付ボルト７のねじ部を挿入する２個のボルト孔３１ａが設けられ、バッテリートレイ２の底面部２ａには、締付ボルト７のねじ部を挿入する取付孔２１がボルト孔３１ａと対応する位置に設けられている。溶接ナット８は、取付孔２１が設けられた底面部２ａの下面に溶接などにより固着されている。 As shown in FIGS. 1, 2 and 7, the main body 31 of the battery holding member 3 is formed by screwing two tightening bolts 7 arranged at intervals in the vehicle width direction into the welding nut 8. , It is attached to the bottom surface 2a of the battery tray 2 in a separated state. By fastening the main body 31 at two points with the tightening bolts 7, the movement of the battery holding member 3 is suppressed and the battery 1 is prevented from being scraped. Further, the end portion of the main body portion 31 on the front holding portion 32 side (rear side of the vehicle) extends to a position close to the front side protrusion shape portion 11 of the battery 1, and the vehicle front side end portion 31b of the main body portion 31 is a battery. It extends to a position where the tray 2 comes into contact with the inclined side surface portion 2b bent toward the front side of the vehicle, and is placed on the side surface portion 2b, and is placed between the upper and lower portions of the main body portion 31 and the bottom surface portion 2a of the battery tray 2. Is formed with a space for arranging the front projection shape portion 11 and the side surface portion 6b of the resin battery tray 6. Therefore, the vehicle front side end portion 31b is bent at substantially the same angle as the inclined surface-shaped side surface portion 2b bent toward the vehicle front side. As a result, the contact area between the battery holding member 3 and the battery 1 and the battery tray 2 is increased so that the movement of the battery 1 while the vehicle is running is further suppressed.
The main body 31 of the battery holding member 3 is provided with two bolt holes 31a for inserting the threaded portion of the tightening bolt 7, and the threaded portion of the tightening bolt 7 is inserted into the bottom surface 2a of the battery tray 2. The mounting hole 21 is provided at a position corresponding to the bolt hole 31a. The welding nut 8 is fixed to the lower surface of the bottom surface portion 2a provided with the mounting hole 21 by welding or the like.

また、本実施形態のバッテリー保持部材３においては、前面保持部３２と側面保持部３３とが本体部３１に一体に形成されている。前面保持部３２は、図１、図２及び図７に示すように、バッテリー１の前面下部１ａの車両幅方向の大きさと同等の幅を有しており、本体部３１の車両後方側の端部から車両上方へ延びるように屈曲形成されている。そのため、前面保持部３２は、バッテリー１の前面下部１ａに当接する前面当接部３２ａと、該前面当接部３２ａの下端側に設けられ、前面側突起形状部１１の水平面部１１ａに載せる設置面部３２ｂとを有している。
したがって、バッテリー１の前面側突起形状部１１は、バッテリー保持部材３の前面保持部３２の設置面部３２ｂを前面側突起形状部１１の水平面部１１ａに載せ、前面当接部３２ａをバッテリー１の前面下部１ａに当接させた状態で締付ボルト７及び溶接ナット８を締結し、本体部３１をバッテリートレイ２の底面部２ａに固定することによって、保持されるように構成されている。 Further, in the battery holding member 3 of the present embodiment, the front holding portion 32 and the side holding portion 33 are integrally formed with the main body portion 31. As shown in FIGS. 1, 2 and 7, the front holding portion 32 has a width equivalent to the size of the front lower portion 1a of the battery 1 in the vehicle width direction, and the end of the main body 31 on the rear side of the vehicle. It is bent so as to extend from the portion to the upper part of the vehicle. Therefore, the front holding portion 32 is provided on the front contact portion 32a that contacts the front lower portion 1a of the battery 1 and the lower end side of the front contact portion 32a, and is placed on the horizontal surface portion 11a of the front protrusion shape portion 11. It has a surface portion 32b.
Therefore, in the front projection shape portion 11 of the battery 1, the installation surface portion 32b of the front holding portion 32 of the battery holding member 3 is placed on the horizontal surface portion 11a of the front projection shape portion 11, and the front contact portion 32a is placed on the front surface of the battery 1. The tightening bolt 7 and the welding nut 8 are fastened in contact with the lower portion 1a, and the main body portion 31 is fixed to the bottom surface portion 2a of the battery tray 2 so as to be held.

側面保持部３３は、図１〜図４に示すように、本体部３１の左右両側部の位置で、所定の長さＬを有する側腕部として形成されており、本体部３１の車両後方側の端部から車両後方へ向かってバッテリー１の側面側突起形状部１３の車両前方側位置まで延びている。しかも、側面保持部３３には、側面側突起形状部１３を保持する側面当接部３３ａと、バッテリー１の車両幅方向の動きを規制する側面規制部３３ｂとが設けられている。側面保持部３３の側面当接部３３ａは、図３及び図４に示すように、側面側突起形状部１３の斜面部１３ａと当接する傾斜面状に形成されており、当該斜面部１３ａと対応する角度で外方へ向かう下り傾斜の傾斜面部として構成されている。また、側面当接部３３ａは、側面側突起形状部１３の斜面部１３ａよりも大きい幅寸法を有しており、下半部分は、側面側突起形状部１３の斜面部１３ａより外側に位置している。そして、側面当接部３３ａの下端には、車両下方へ延びるフランジ部３３ｃを有しており、当該フランジ部３３ｃは、樹脂製バッテリートレイ６の側面部６ｂの外側に近接して位置し、側面部６ｂの上端と係合可能に配置されている。また、側面保持部３３の側面規制部３３ｂは、側面当接部３３ａの上端から車両上方へ延び、バッテリー１の側面下部１ｃに対して平行に近接して位置するフランジ部状に形成されている。そのため、側面保持部３３は、側面規制部３３ｂ、側面当接部３３ａ及びフランジ部３３ｃが車両上下方向に連続して形成されており、側面保持部３３の断面形状は、側面規制部３３ｂ、側面当接部３３ａ及びフランジ部３３ｃにより、車両前方視でやや横向きの略Ｓ字形状を有している。
したがって、バッテリー１の側面側突起形状部１３は、バッテリー保持部材３の側面保持部３３の側面当接部３３ａを側面側突起形状部１３の斜面部１３ａに載せて当接させ、側面規制部３３ｂをバッテリー１の側面下部１ｃに近接させて配置するとともに、フランジ部３３ｃを樹脂製バッテリートレイ６の側面部６ｂの外側に近接させて配置した状態で締付ボルト７及び溶接ナット８を締結し、本体部３１をバッテリートレイ２の底面部２ａに固定することによって、保持されるように構成されている。 As shown in FIGS. 1 to 4, the side surface holding portion 33 is formed as a side arm portion having a predetermined length L at the positions of the left and right side portions of the main body portion 31, and is formed on the vehicle rear side of the main body portion 31. It extends from the end of the battery 1 toward the rear of the vehicle to the position on the front side of the vehicle of the side protrusion shape portion 13 of the battery 1. Moreover, the side surface holding portion 33 is provided with a side surface contact portion 33a for holding the side surface side protrusion shape portion 13 and a side surface regulating portion 33b for restricting the movement of the battery 1 in the vehicle width direction. As shown in FIGS. 3 and 4, the side surface contact portion 33a of the side surface holding portion 33 is formed in an inclined surface shape that abuts on the slope portion 13a of the side protrusion shape portion 13, and corresponds to the slope portion 13a. It is configured as an inclined surface portion that is inclined downward toward the outside at an angle. Further, the side contact portion 33a has a width dimension larger than that of the slope portion 13a of the side protrusion shape portion 13, and the lower half portion is located outside the slope portion 13a of the side protrusion shape portion 13. ing.

次いで、バッテリー保持部材３をバッテリートレイ２の車両前方側に設置し、バッテリー保持部材３の前面保持部３２の設置面部３２ｂを前面側突起形状部１１の水平面部１１ａに載せるとともに、前面当接部３２ａをバッテリー１の前面下部１ａに当接させる。また、バッテリー保持部材３の側面保持部３３の側面当接部３３ａを側面側突起形状部１３の斜面部１３ａに載せて当接させ、側面規制部３３ｂをバッテリー１の側面下部１ｃに近接させて配置するとともに、フランジ部３３ｃを樹脂製バッテリートレイ６の側面部６ｂの外側に近接させて配置する。
しかる後、バッテリー保持部材３のボルト孔３１ａ及びバッテリートレイ２の取付孔２１を介して締付ボルト７を溶接ナット８に螺合させて締結し、本体部３１をバッテリートレイ２の底面部２ａに固定すれば、バッテリー１の前面側突起形状部１１は、バッテリー保持部材３の前面保持部３２に押え付けられて保持され、バッテリー１の後面側突起形状部１２はバッテリートレイ２の車両後方側に位置する係止形状部２２に押し付けられて保持されるとともに、バッテリー１の側面側突起形状部１３は、バッテリー保持部材３の側面保持部３３に押え付けられて保持され、作業が終了することになる（図１〜図３及び図７参照）。 Next, the battery holding member 3 is installed on the vehicle front side of the battery tray 2, the installation surface portion 32b of the front holding portion 32 of the battery holding member 3 is placed on the horizontal surface portion 11a of the front side protrusion shape portion 11, and the front contact portion is formed. The 32a is brought into contact with the lower front lower portion 1a of the battery 1. Further, the side surface contact portion 33a of the side surface holding portion 33 of the battery holding member 3 is placed on the slope portion 13a of the side surface protrusion shape portion 13 and brought into contact with the side surface regulating portion 33b so as to be close to the side surface lower portion 1c of the battery 1. The flange portion 33c is arranged so as to be close to the outside of the side surface portion 6b of the resin battery tray 6.
After that, the tightening bolt 7 is screwed into the welding nut 8 through the bolt hole 31a of the battery holding member 3 and the mounting hole 21 of the battery tray 2 and fastened, and the main body 31 is attached to the bottom surface 2a of the battery tray 2. When fixed, the front projection shape portion 11 of the battery 1 is pressed and held by the front holding portion 32 of the battery holding member 3, and the rear projection shape portion 12 of the battery 1 is on the vehicle rear side of the battery tray 2. The side projection shape portion 13 of the battery 1 is pressed and held by the side surface holding portion 33 of the battery holding member 3 while being pressed and held by the positioned locking shape portion 22, and the work is completed. (See FIGS. 1 to 3 and 7).

このように、本発明の実施形態に係る車両用バッテリー１の保持構造では、バッテリー１の前面下部１ａ及び後面下部１ｂに設けられた前面側突起形状部１１及び後面側突起形状部１２を固定することにより、バッテリー１がバッテリートレイ２に保持されるようになっており、バッテリートレイ２には、バッテリー１を保持するバッテリー保持部材３が設けられ、バッテリー保持部材３は、バッテリー１の前面下部１ａに沿って車両幅方向に延びる前面保持部３２と、バッテリー１の側面下部１ｃに沿って車両前後方向に延びる側面保持部３３を有し、前面側突起形状部１１が、バッテリー保持部材３の前面保持部３２によって保持され、バッテリー１の側面下部１ｃに設けられた側面側突起形状部１３の車両前方側が、バッテリー保持部材３の側面保持部３３によって保持されているので、車両走行中の車体に発生する振動や後突時の衝撃による慣性力で車両前後方向に移動しようとするバッテリー１の前面側突起形状部１１及び側面側突起形状部１３とバッテリー保持部材３の前面保持部３２及び側面保持部３３とが外れにくくなっている。したがって、本実施形態の保持構造によれば、バッテリー１がバッテリートレイ２から外れてしまう不具合を防止することができ、バッテリー１をバッテリートレイ２に長期間にわたり安定して保持することができる。 As described above, in the holding structure of the vehicle battery 1 according to the embodiment of the present invention, the front side projection shape portion 11 and the rear surface side protrusion shape portion 12 provided on the front lower portion 1a and the rear surface lower portion 1b of the battery 1 are fixed. As a result, the battery 1 is held in the battery tray 2, the battery tray 2 is provided with a battery holding member 3 for holding the battery 1, and the battery holding member 3 is the lower front lower portion 1a of the battery 1. A front holding portion 32 extending in the vehicle width direction along the battery 1 and a side holding portion 33 extending in the vehicle front-rear direction along the side lower portion 1c of the battery 1, and the front protruding shape portion 11 is the front surface of the battery holding member 3. The front side of the vehicle, which is held by the holding portion 32 and is provided on the lower side surface portion 1c of the battery 1 by the side surface holding portion 33 of the battery holding member 3, is held by the side holding portion 33 of the battery holding member 3, so that the vehicle body can be used while the vehicle is running. The front side protrusion shape portion 11 and the side protrusion shape portion 13 of the battery 1 and the front holding portion 32 and the side holding portion 3 of the battery holding member 3 that try to move in the front-rear direction of the vehicle due to the inertial force due to the generated vibration and the impact at the time of rear collision. The portion 33 is hard to come off. Therefore, according to the holding structure of the present embodiment, it is possible to prevent the battery 1 from coming off the battery tray 2, and the battery 1 can be stably held in the battery tray 2 for a long period of time.

また、本実施形態の保持構造では、後突時の衝撃荷重でバッテリー１が後端部を中心に持ち上がり、車両後方に回転しようとしても、回転中心から遠い箇所であるバッテリー１の前面部及び側面部の車両前方側がバッテリー保持部材３の前面保持部３２及び側面保持部３３によって押え付けられているので、バッテリー１の車両後方回転の動きを抑制でき、バッテリー１とバッテリー保持部材３とが外れにくく、バッテリー１がバッテリートレイ２から外れてしまうという不具合の発生を低減させることができる。さらに、バッテリー保持部材３の側面保持部３３によってバッテリー１が側面部までしっかりと保持されているので、車両走行時の車両幅方向への動きに対してもバッテリー１の同方向への動きを規制し、バッテリー保持部材３によるバッテリー１の削りを回避できるとともに、車両幅方向にバッテリー保持部材３がバッテリー１から外れるという事態を防止することができる。 Further, in the holding structure of the present embodiment, the battery 1 is lifted around the rear end portion by the impact load at the time of rear collision, and even if the battery 1 tries to rotate to the rear of the vehicle, the front portion and the side surface of the battery 1 which are far from the rotation center. Since the front side of the vehicle is pressed by the front holding portion 32 and the side holding portion 33 of the battery holding member 3, the movement of the battery 1 rotating backward in the vehicle can be suppressed, and the battery 1 and the battery holding member 3 are hard to come off. , It is possible to reduce the occurrence of a problem that the battery 1 comes off from the battery tray 2. Further, since the battery 1 is firmly held up to the side surface by the side surface holding portion 33 of the battery holding member 3, the movement of the battery 1 in the same direction is restricted even with respect to the movement in the vehicle width direction when the vehicle is running. Therefore, it is possible to avoid scraping the battery 1 by the battery holding member 3, and it is possible to prevent the battery holding member 3 from coming off the battery 1 in the vehicle width direction.

また、本実施形態の保持構造においては、前面保持部３２と側面保持部３３がバッテリー保持部材３の本体部３１に一体に形成され、前面保持部３２は、バッテリー１の前面下部１ａの車両幅方向の大きさと同等の幅を有し、側面保持部３３には、側面側突起形状部１３を保持する側面当接部３３ａと、バッテリー１の車両幅方向の動きを規制する側面規制部３３ｂとが設けられているので、位置関係などが異なる前面保持部３２及び側面保持部３３という２つの保持部同士間のばらつきが発生しにくくなり、組付け後のガタツキなどを低減させ、前面保持部３２及び側面保持部３３のよる保持効果をより高めることができるとともに、部品点数及び組付け工数の増加を防ぐことができる。しかも、バッテリー１及びバッテリートレイ２に対するバッテリー保持部材３の位置決めが容易となり、バッテリー保持部材３の組付け作業が容易に行えるので、バッテリー１の前面側突起形状部１１及び側面側突起形状部１３に対する前面保持部３２及び側面保持部３３のズレを抑えることができる。 Further, in the holding structure of the present embodiment, the front holding portion 32 and the side holding portion 33 are integrally formed with the main body portion 31 of the battery holding member 3, and the front holding portion 32 is the vehicle width of the front lower portion 1a of the battery 1. The side surface holding portion 33 has a width equivalent to the size in the direction, and includes a side surface contact portion 33a that holds the side surface side protrusion shape portion 13 and a side surface regulating portion 33b that regulates the movement of the battery 1 in the vehicle width direction. Is provided, so that variations between the two holding portions, the front holding portion 32 and the side holding portion 33, which have different positional relationships, are less likely to occur, rattling after assembly is reduced, and the front holding portion 32 is provided. The holding effect of the side surface holding portion 33 can be further enhanced, and an increase in the number of parts and assembling man-hours can be prevented. Moreover, since the battery holding member 3 can be easily positioned with respect to the battery 1 and the battery tray 2 and the battery holding member 3 can be easily assembled, the front side protrusion shape portion 11 and the side protrusion shape portion 13 of the battery 1 can be easily assembled. The displacement of the front holding portion 32 and the side holding portion 33 can be suppressed.

さらに、本実施形態の保持構造では、側面保持部３３の側面当接部３３ａが側面側突起形状部１３の斜面部１３ａと当接する傾斜面状に形成され、下端に車両下方へ延びるフランジ部３３ａを有し、側面保持部３３の側面規制部３３ｂが、側面当接部３３ａの上端から車両上方へ延び、バッテリー１の側面下部１ｃに対して平行に近接して位置するフランジ部状に形成され、側面保持部３３の断面形状が、側面当接部３３ａと側面規制部３３ｂとにより、車両前方視で略Ｓ字形状を有している。
したがって、側面保持部３３の側面当接部３３ａが側面側突起形状部１３の斜面部１３ａを保持することによって、バッテリー１とバッテリー保持部材３との位置決めが容易となるので、バッテリー１をバッテリートレイ２に確実に保持することができる。また、側面保持部３３が車両前方視で略Ｓ字形状の断面を有することで、側面保持部３３の強度が向上し、バッテリー１の車両幅方向の動きが側面規制部３３ｂにより規制されているので、外部から荷重がバッテリー保持部材３に加わった場合に、側面保持部３３の変形を抑制することが可能となり、車体振動などによりバッテリー１が車両幅方向に揺れ動くのを確実に防止し、バッテリー１とバッテリー保持部材３とが擦れて削れてしまう可能性を低減させることができる。 Further, in the holding structure of the present embodiment, the side surface contact portion 33a of the side surface holding portion 33 is formed in an inclined surface shape that abuts on the slope portion 13a of the side surface side protrusion shape portion 13, and the flange portion 33a extending downward to the lower end of the vehicle is formed. The side surface restricting portion 33b of the side surface holding portion 33 extends upward from the upper end of the side surface contact portion 33a to the upper side of the vehicle, and is formed in the shape of a flange portion located in parallel with the lower side portion 1c of the battery 1. The cross-sectional shape of the side surface holding portion 33 has a substantially S shape when viewed from the front of the vehicle due to the side surface contact portion 33a and the side surface regulating portion 33b.
Therefore, since the side contact portion 33a of the side holding portion 33 holds the slope portion 13a of the side protrusion shape portion 13, the positioning of the battery 1 and the battery holding member 3 becomes easy, so that the battery 1 can be placed in the battery tray. It can be reliably held at 2. Further, since the side surface holding portion 33 has a substantially S-shaped cross section when viewed from the front of the vehicle, the strength of the side surface holding portion 33 is improved, and the movement of the battery 1 in the vehicle width direction is regulated by the side surface regulating portion 33b. Therefore, when a load is applied to the battery holding member 3 from the outside, the deformation of the side holding portion 33 can be suppressed, and the battery 1 can be reliably prevented from swinging in the vehicle width direction due to vehicle body vibration or the like, and the battery. It is possible to reduce the possibility that 1 and the battery holding member 3 are rubbed and scraped.

そして、本実施形態の保持構造においては、後面側突起形状部１２が斜面部１２ａと縦壁部１２ｂを有し、バッテリートレイ２の車両後方側には、後面側突起形状部１２を保持する係止形状部２２が設けられ、係止形状部２２は、後面側突起形状部１２の斜面部１２ａと当接する後面当接部２２ａを有しているとともに、後面側突起形状部１２の縦壁部１２ｂに隣接して配置され、車両幅方向に間隔を空けて設けられる複数の凹形状部２２ｂを有している。
したがって、後面側突起形状部１２の斜面部１２ａが係止形状部２２の後面当接部２２ａに当接した状態で保持されることになるので、バッテリー１の後面下部１ｂをバッテリートレイ２に位置決めしながら確実に保持することができる。また、係止形状部２２の剛性及び強度が凹形状部２２ｂの存在によって向上しているので、後突時の衝撃による慣性力でバッテリー１が車両後方に移動した際の係止形状部２２の変形を防ぐことができる。しかも、凹形状部２２ｂが後面側突起形状部１２の縦壁部１２ｂに隣接して配置されているので、凹形状部２２ｂがバッテリー１の後面側突起形状部１２のストッパーとして働き、バッテリー１が車両後方に大きく移動しないようにすることができる。さらに、バッテリー１の車両方向への移動量が小さくなるため、衝突時の慣性力で生じる係止形状部２２に掛かる衝撃荷重を低減させ、係止形状部２２の変形が発生しにくくすることができ、バッテリー１がバッテリートレイ２から外れる可能性を小さくすることができる。 In the holding structure of the present embodiment, the rear surface side protrusion shape portion 12 has a slope portion 12a and a vertical wall portion 12b, and the rear surface side protrusion shape portion 12 is held on the vehicle rear side of the battery tray 2. A stop shape portion 22 is provided, and the locking shape portion 22 has a rear surface contact portion 22a that abuts on the slope portion 12a of the rear surface side protrusion shape portion 12, and also has a vertical wall portion of the rear surface side protrusion shape portion 12. It has a plurality of concave-shaped portions 22b arranged adjacent to the 12b and provided at intervals in the vehicle width direction.
Therefore, the slope portion 12a of the rear surface side protrusion shape portion 12 is held in a state of being in contact with the rear surface contact portion 22a of the locking shape portion 22, so that the rear surface lower portion 1b of the battery 1 is positioned on the battery tray 2. However, it can be held securely. Further, since the rigidity and strength of the locking shape portion 22 are improved by the presence of the concave shape portion 22b, the locking shape portion 22 when the battery 1 moves to the rear of the vehicle due to the inertial force due to the impact at the time of rear collision. Deformation can be prevented. Moreover, since the concave shape portion 22b is arranged adjacent to the vertical wall portion 12b of the rear surface side protrusion shape portion 12, the concave shape portion 22b acts as a stopper for the rear surface side protrusion shape portion 12 of the battery 1, and the battery 1 It is possible to prevent the vehicle from moving significantly behind the vehicle. Further, since the amount of movement of the battery 1 in the vehicle direction is small, the impact load applied to the locking shape portion 22 generated by the inertial force at the time of collision can be reduced, and the locking shape portion 22 can be less likely to be deformed. This makes it possible to reduce the possibility that the battery 1 will come off the battery tray 2.

また、本実施形態の保持構造において、バッテリートレイ２の車両後方側端部の上部には、車両幅方向に沿って延びるバッテリートレイメンバー５が設けられ、該バッテリートレイメンバー５は、バッテリー１の重心Ｇ位置の高さＨ以上の高さに配置されているので、後突時にバッテリー１が後面側突起形状部１２と係止形状部２２との引っ掛け部分を中心に車両後方へ回転しようとする動きをバッテリートレイメンバー５によって抑えることができ、バッテリー１がバッテリー保持部材３から外れるのを防止することができる。 Further, in the holding structure of the present embodiment, a battery tray member 5 extending along the vehicle width direction is provided above the rear end of the battery tray 2 on the vehicle rear side, and the battery tray member 5 is the center of gravity of the battery 1. Since the battery 1 is arranged at a height equal to or higher than the height H of the G position, the battery 1 tends to rotate rearward of the vehicle around the hooked portion between the rear projection shape portion 12 and the locking shape portion 22 at the time of rear collision. Can be suppressed by the battery tray member 5, and the battery 1 can be prevented from coming off from the battery holding member 3.
