電動車両のバッテリ保持装置Battery holding device for electric vehicle
　本発明は、電動車両のバッテリ保持装置に関する。 The present invention relates to a battery holding device for an electric vehicle.
　近年、トラック等の商用車においても、環境負荷低減の観点から、エンジンとモータとを駆動源とするハイブリッド自動車（ＨＥＶ）や、モータのみを駆動源とする電気自動車（ＥＶ）等の電動車両が開発されている。このような商用車には、モータを作動させるための大容量のバッテリが搭載されている。例えば特許文献１には、トラックのフレームを構成するサイドレールの車幅方向外側（側方）にバッテリを配置した電動車両のバッテリユニットが開示されている。 In recent years, electric vehicles such as hybrid vehicles (HEV) that use an engine and a motor as drive sources and electric vehicles (EV) that use only a motor as a drive source are also used in commercial vehicles such as trucks from the viewpoint of reducing environmental impact. Has been developed. Such a commercial vehicle is equipped with a large-capacity battery for operating the motor.

　ところで、近年、車両の航続距離を延長する観点から、複数のバッテリを車両に搭載することが求められている。車両の航続距離をさらに延長するべくより多くのバッテリ搭載要求があり、また、車両の構成ユニットのレイアウト上の制約がある場合、サイドレール間にバッテリを配置する必要が生じる。 Incidentally, in recent years, it has been required to mount a plurality of batteries on a vehicle from the viewpoint of extending the cruising range of the vehicle. In order to further extend the cruising distance of the vehicle, there is a demand for more batteries to be mounted, and when there are restrictions on the layout of the constituent units of the vehicle, it is necessary to arrange the batteries between the side rails.
　しかし、バッテリ交換等の整備の際、トラック等の商用車は、乗用車と異なり、フレーム上にバンボディ（荷箱）等が架装されることから、フレームの上側からバッテリにアクセスするのは困難である。一方、フレームの下側からバッテリにアクセスする場合であっても、サイドレール間に配置したバッテリを交換する等して整備する際、サイドレール間の狭いスペースで作業を行わなければならないため、整備性の悪化が懸念される。 However, during maintenance such as battery replacement, unlike commercial vehicles, trucks and other commercial vehicles have van bodies (packaging boxes) mounted on the frame, making it difficult to access the battery from the upper side of the frame. is there. On the other hand, even when accessing the battery from the lower side of the frame, maintenance must be performed in a narrow space between the side rails when maintenance is performed by replacing the battery disposed between the side rails. There is concern about the deterioration of sex.
　本発明はこのような問題の少なくとも一部を解決するためになされたもので、その目的とするところは、バッテリ交換等のバッテリに係る整備性を向上することができる、電動車両のバッテリ保持装置を提供することにある。 The present invention has been made to solve at least a part of such problems, and an object of the present invention is to provide a battery holding device for an electric vehicle that can improve the maintainability of the battery such as battery replacement.

On the other hand, the connection bracket 13 is composed of two inner frames 13a in which the above-described connection portions 12 are respectively formed, and two outer frames 13b coupled to the outer ends of the inner frames 13a in the vehicle width direction Y. Yes. The outer end of each outer frame 13 b is coupled to the inner surface 5 b of the side rail 5.
　こうして、保持ブラケット１１で保持された各バッテリ９を連結ブラケット１３を介してサイドレール５で支持するバッテリ保持装置１０が構成されている。そして、連結ブラケット１３の連結部１２にて保持ブラケット１１の連結及び連結解除を行うことにより、二段積みの各バッテリ９を保持ブラケット１１に保持した状態でトラック１の下側から保持ブラケット１１ごと着脱可能である。 Thus, the battery holding device 10 is configured to support each battery 9 held by the holding bracket 11 with the side rail 5 via the connection bracket 13. Then, the holding bracket 11 is connected and disconnected at the connecting portion 12 of the connecting bracket 13, so that each holding bracket 11 is held from the lower side of the track 1 in a state where the two-stage stacked batteries 9 are held by the holding bracket 11. Detachable.
　ここで、図２から明らかなように、連結ブラケット１３の各連結部１２は車高方向Ｚにて各サイドレール５の下方に配設されている。即ち、連結部１２が車高方向Ｚにて各フレームよりも下方に配設されることから、連結部１２へのアクセスが容易となる。また、各バッテリ９を保持ブラケット１１に保持した状態でトラック１の下側から保持ブラケット１１ごと着脱する際、即ち、連結部１２に対する係合部１８の係合及び係合解除の作業を行う際、各サイドレール５の下方の比較的広いスペースで作業を行うことができる。 Here, as is apparent from FIG. 2, each connecting portion 12 of the connecting bracket 13 is disposed below each side rail 5 in the vehicle height direction Z. That is, since the connecting portion 12 is disposed below each frame in the vehicle height direction Z, access to the connecting portion 12 is facilitated. Further, when each battery 9 is held by the holding bracket 11 and is attached and detached together with the holding bracket 11 from the lower side of the track 1, that is, when the engaging portion 18 is engaged with and released from the connecting portion 12. The work can be performed in a relatively wide space below each side rail 5.
　従って、バンボディ３及びキャビン４等の架装物が配置された各サイドレール５の上側からアクセスして作業を行う場合や、各サイドレール５間の狭いスペースで作業を行う場合に比して、各バッテリ９交換等のバッテリ９に係る整備性を大幅に向上することができる。
　また、本実施形態に係るバッテリ保持装置１０においては、積層されたバッテリ９を保持ブラケット１１に保持した状態でトラック１の下側から保持ブラケット１１ごと着脱可能であることから、サイドレール５間のスペースを利用して、できるだけ多くのバッテリ９を搭載可能となり、トラック１の航続距離を延長することもできる。 Therefore, compared with the case where work is performed by accessing from the upper side of each side rail 5 where the bodywork such as the van body 3 and the cabin 4 is arranged, or when working in a narrow space between the side rails 5, The maintainability of the battery 9 such as replacement of each battery 9 can be greatly improved.
Further, in the battery holding device 10 according to the present embodiment, since the stacked batteries 9 are held by the holding bracket 11 and can be attached and detached together with the holding bracket 11 from the lower side of the track 1, Using space, it is possible to mount as many batteries 9 as possible, and the cruising distance of the truck 1 can be extended.
　以上で本発明に係るバッテリ保持装置１０の実施形態についての説明を終えるが、実施形態は上記実施形態に限られるものではない。 The description of the embodiment of the battery holding device 10 according to the present invention is finished above, but the embodiment is not limited to the above embodiment.
　例えば、図４に示すように、バッテリ９を上側一段積みの搭載とした保持ブラケット１９としても良く、また、図５に示すように、バッテリ９を下側一段積みの搭載とした保持ブラケット２０としても良い。これらの場合であっても、連結ブラケット１３の連結部１２は、車高方向Ｚにて各サイドレール５よりも下方に配設されるため、少なくともバッテリ９の交換に係る整備性を向上することが可能である。また、バッテリ９を一段積みとしたことにより、トラック１の構成ユニットのレイアウトの自由度がさらに向上するとの利点もある。 For example, as shown in FIG. 4, the battery 9 may be a holding bracket 19 mounted on the upper side stack, and as shown in FIG. 5, the holding bracket 20 may be mounted on the lower side stack. Also good. Even in these cases, the connecting portion 12 of the connecting bracket 13 is disposed below the side rails 5 in the vehicle height direction Z, so that at least the maintainability related to the replacement of the battery 9 is improved. Is possible. Further, since the batteries 9 are stacked in one stage, there is an advantage that the degree of freedom of layout of the constituent units of the truck 1 is further improved.
　また、上記実施形態の保持ブラケット１１や連結ブラケット１３は、上述した構造に限定されるものではなく、バッテリ９の脱落を阻止しながら、バッテリ９を支持可能であり、トラック１の走行中の振動による衝撃に耐え得る剛性及び強度を有していれば、種々の構造が想定可能である。 Further, the holding bracket 11 and the connecting bracket 13 of the above-described embodiment are not limited to the above-described structure, and can support the battery 9 while preventing the battery 9 from dropping off, and vibration during traveling of the truck 1. Various structures can be envisaged as long as they have rigidity and strength that can withstand the impact caused by.
　また、上記実施形態では、本発明をハイブリッド型のトラック１に適用した場合について説明したが、ハイブリッド型のバスや乗用車に適用しても良いし、走行用動力源としてモータのみを備えた電気自動車に適用しても良い。 Moreover, although the case where the present invention is applied to the hybrid truck 1 has been described in the above embodiment, the present invention may be applied to a hybrid bus or a passenger car, or an electric vehicle including only a motor as a driving power source. You may apply to.
