【０００１】
【発明の属する技術分野】
本発明は電気自動車用バッテリーパックの収納機構およびバッテリーパックの着脱装置に関し、特に重量物であるバッテリーパックを一括して車両に収納するための収納機構およびその収納に便利なバッテリーパックの着脱装置に関する。
【０００２】
【従来の技術】
従来、電気自動車用バッテリーは、例えば乗員用座席の下などの狭いスペースに収納される。この配置によれば、ドアの開度がさほどに大きくなく、バッテリーの保守点検及び着脱の際にバッテリーの交換作業が煩雑であるとともに、その作業に長時間を要している。しかもバッテリー自体、相当な重量物であり、円滑な保守点検、移載作業が困難である等、種々の不都合が指摘されている。
【０００３】
【発明が解決しようとする課題】
本発明は前記の不都合を克服するためになされたものであり、電気自動車用バッテリーパックを容易且つ短時間に移載でき、しかも保守点検と交換作業も容易に行うことが可能な電気自動車用バッテリーパックの収納機構およびバッテリーパックの着脱装置を提供することを目的とする。
【０００４】
【課題を解決するための手段】
本発明に係る電気自動車用バッテリーパックの収納機構は、車両の後方側にバッテリーパックを収納するケーシングを設け、前記ケーシングは前記バッテリーパックを移載するための爪部材を受容する凹部を有し、さらに前記バッテリーパックから電源を取り出す出力用端子と該バッテリーパックに充電を行う充電用端子とを設けることを特徴とする。
【０００５】
本発明によれば、バッテリーパックを保持する爪部材が凹部に挿入されるので、ケーシング内に容易にバッテリーパックを収納することができる。
【０００６】
また、本発明に係るバッテリーパックの着脱装置は、移動自在なフレームと、該フレームに固着されたポールに沿って上下動してバッテリーパックを移載する爪部材と、この爪部材に平行に設けられた押さえ部材と、前記爪部材と押さえ部材とを一体的に上下動させる揺動部材とを有し、前記押さえ部材は前記爪部材と共働して移載されるバッテリーパックを収納する空間を形成することを特徴とする。
【０００７】
本発明によれば、押さえ部材と爪部材との間にバッテリーパックを保持した後、爪部を揺動させてバッテリーパックを爪部材と共に上昇させるようにしたため、容易にケーシング内にバッテリーパックを収納できる。このため、短時間に効率よくバッテリーパックの交換が可能である。
【０００８】
【発明の実施の形態】
本発明にかかる電気自動車のバッテリーパックの収納機構およびバッテリーパックの着脱装置について好適な実施の形態を掲げ、以下詳細に説明する。
【０００９】
図において参照符号１０はセダンタイプの電気自動車を示す。前記電気自動車１０の後部に、バッテリーパック用収納スペース１２が設けられる。前記スペース１２にはバッテリーパックＰを収納するためのケーシング１４が配置される。
【００１０】
ケーシング１４の底面には後方から前方に指向して２本の平行に延在する長い凹部２２ａ、２２ｂを設け、同様に該ケーシング１４の上面にも後方から前方へ向けて２本の短い凹部２４ａ、２４ｂを平行に設ける。前記ケーシング１４にはその内部に一括収納したバッテリーパックＰから電源を取り出すための出力用端子１６と該バッテリーパックＰへ電源を充電するための充電用端子１８を設ける。すなわち、バッテリーパックＰの図示しない端子は、ケーシング１４に挿入されたことにより、前記出力用端子と充電用端子に電気的に接続される。
【００１１】
以上のように構成されるバッテリーの収納機構に対してバッテリーパックＰを着脱するための装置について説明する。
【００１２】
着脱装置３０は水平方向に延在する長方形状のフレーム３２を有し、該フレーム３２は、補強部材３３によってその強度が補強されるとともに、それぞれの隅角部に回転自在に枢着された車輪３４ａ〜３４ｄによって支持されている。
【００１３】
前記フレーム３２の後端に、２本の平行に延在するポール３６ａ、３６ｂを垂設し、これらのポール３６ａ、３６ｂの下端部に切欠３８ａ、３８ｂを設ける。当該切欠３８ａ、３８ｂに２本のアーム４０ａ、４０ｂの一端部がピン部材４２ａ、４２ｂを介して回動自在に固着されている。そして前記ポール３６ａ、３６ｂのアーム４０ａ、４０ｂとは反対側に、該アーム４０ａ、４０ｂとほぼ直角に延在する２本の支柱４４ａ、４４ｂを延在させ、該支柱４４ａ、４４ｂの一端部を前記切欠３８ａ、３８ｂに挿入して前記ピン部材４２ａ、４２ｂによって枢支する。すなわち、アーム４０ａ、４０ｂと支柱４４ａ、４４ｂとはそれぞれの端部で連結されており、共通のピン部材４２ａ、４２ｂにより揺動自在である。
【００１４】
支柱４４ａ、４４ｂの他端部には横架部材４６が橋架され、該横架部材４６の両端部にローラ４８ａ、４８ｂが回転自在に設けられている。一方、ポール３６ａ、３６ｂにはそれぞれ長尺な爪部材５０ａ、５０ｂがその軸線に沿って変位自在に設けられる。しかも、該ポール３６ａ、３６ｂには前記爪部材５０ａ、５０ｂと平行に且つ一体的に押さえ部材５２ａ、５２ｂが設けられる。この場合、前記爪部材５０ａ、５０ｂの長さはケーシング１４の凹部２２ａ、２２ｂの長さと同じであり、前記押さえ部材５２ａ、５２ｂの長さは凹部２４ａ、２４ｂの長さと同じである。前記ローラ４８ａ、４８ｂは、前記ポール３６ａ、３６ｂの垂直方向に変位自在な爪部材５０ａ、５０ｂの下面にそれぞれ当接する。前記爪部材５０ａ、５０ｂと平行に設けられたポール３６ａ、３６ｂには押さえ部材５２ａ、５２ｂが設けられている。従って、前記爪部材５０ａ、５０ｂと押さえ部材５２ａ、５２ｂとの間でバッテリーパックＰを収納する空間Ｓが画成される。なお、図３、図４において、参照符号６０はアーム４０ａ、４０ｂに橋架された把手を示し、参照符号６２は爪部材５０ａ、５０ｂ間に橋架された横架板を示す。
【００１５】
本発明の実施の形態にかかる電気自動車用バッテリーパックの収納機構およびバッテリーパックの着脱装置は上記のように構成されており、次にその作用について説明する。
【００１６】
先ず、電気自動車１０のバッテリーパックＰをケーシング１４に収納する。この場合、バッテリーパックＰは爪部材５０ａ、５０ｂ上に戴置され、押さえ部材５２ａ、５２ｂとの間で画成された空間Ｓに保持される。
【００１７】
次に、着脱装置３０を押して車輪３４ａ〜３４ｄの回転作用下に、電気自動車１０の後方に移動し、把手６０を手前に押圧回動させればローラ４８ａ、４８ｂは爪部材５０ａ、５０ｂの下面を滑動して、テコの原理によって押さえ部材５２ａ、５２ｂとともに上昇可能である。そして長い舌片状の爪部材５０ａ、５０ｂをケーシング１４の底面の長い凹部２２ａ、２２ｂに挿入する。この時、同時に短い舌片状の押さえ部材５２ａ、５２ｂもケーシング１４上面の短い凹部２４ａ、２４ｂに挿入される。つまりケーシング１４は、着脱装置３０の長い舌片状の爪部材５０ａ、５０ｂと、短い押さえ部材５２ａ、５２ｂとで挟まれた状態でケーシング１４内に移動される。そして、把手６０に対する押圧動作を解除すれば、バッテリーパックＰはケーシング１４内に設置される。そして、着脱装置３０は爪部材５０ａ、５０ｂ、押さえ部材５２ａ、５２ｂを引き抜くように退動する。なお、ケーシング１４に既に収納されているバッテリーパックＰを取り出す際には、前記と逆の動作を行えば良いことは容易に諒解されよう。
【００１８】
【発明の効果】
本発明によれば、バッテリーパックを電気自動車に対して容易に収納し、且つ取り出すことができるため、作業を極めて短時間に且つ確実に行うことが可能となる。従って、バッテリーパック自体の保守点検も簡易化できる。

[0009]
In the figure, reference numeral 10 indicates a sedan type electric vehicle. A battery pack storage space 12 is provided at the rear of the electric vehicle 10. A casing 14 for storing the battery pack P is disposed in the space 12.
[0010]
The bottom surface of the casing 14 is provided with two long concave portions 22a and 22b extending in parallel from the rear to the front. Similarly, the upper surface of the casing 14 has two short concave portions 24a from the rear to the front. 24b are provided in parallel. The casing 14 is provided with an output terminal 16 for taking out the power from the battery pack P collectively stored therein, and a charging terminal 18 for charging the power to the battery pack P. That is, a terminal (not shown) of the battery pack P is electrically connected to the output terminal and the charging terminal by being inserted into the casing 14.
[0011]
An apparatus for attaching / detaching the battery pack P to / from the battery storage mechanism configured as described above will be described.
[0012]
The attachment / detachment device 30 has a rectangular frame 32 extending in the horizontal direction. The frame 32 has its strength reinforced by a reinforcing member 33, and a wheel pivotally attached to each corner. It is supported by 34a-34d.
[0013]
Two parallelly extending poles 36a and 36b are suspended from the rear end of the frame 32, and notches 38a and 38b are provided at lower ends of the poles 36a and 36b. One ends of two arms 40a and 40b are fixed to the notches 38a and 38b via pin members 42a and 42b so as to be rotatable. Two poles 44a and 44b extending substantially perpendicular to the arms 40a and 40b are extended on the opposite side of the poles 36a and 36b from the arms 40a and 40b, and one end of each of the poles 44a and 44b is extended. Inserted into the notches 38a, 38b and pivotally supported by the pin members 42a, 42b. That is, the arms 40a, 40b and the support columns 44a, 44b are connected at their respective ends, and can be swung by the common pin members 42a, 42b.
[0014]
A horizontal member 46 is bridged to the other ends of the columns 44 a and 44 b, and rollers 48 a and 48 b are rotatably provided at both ends of the horizontal member 46. On the other hand, long pawl members 50a and 50b are provided on the poles 36a and 36b, respectively, so that they can be displaced along their axes. Moreover, the poles 36a and 36b are provided with pressing members 52a and 52b in parallel and integrally with the claw members 50a and 50b. In this case, the lengths of the claw members 50a and 50b are the same as the lengths of the recesses 22a and 22b of the casing 14, and the lengths of the pressing members 52a and 52b are the same as the lengths of the recesses 24a and 24b. The rollers 48a and 48b are in contact with the lower surfaces of the claw members 50a and 50b that are displaceable in the vertical direction of the poles 36a and 36b, respectively. Holding members 52a and 52b are provided on poles 36a and 36b provided in parallel with the claw members 50a and 50b. Therefore, a space S for storing the battery pack P is defined between the claw members 50a and 50b and the pressing members 52a and 52b. 3 and 4, reference numeral 60 indicates a handle bridged by the arms 40a and 40b, and reference numeral 62 indicates a horizontal plate bridged between the claw members 50a and 50b.
[0015]
The electric vehicle battery pack storage mechanism and the battery pack attachment / detachment device according to the embodiment of the present invention are configured as described above, and the operation thereof will be described below.
[0016]
First, the battery pack P of the electric vehicle 10 is stored in the casing 14. In this case, the battery pack P is placed on the claw members 50a and 50b and is held in the space S defined between the pressing members 52a and 52b.
[0017]
Next, if the attachment / detachment device 30 is pushed to move to the rear of the electric vehicle 10 under the rotating action of the wheels 34a to 34d and the handle 60 is pressed and rotated forward, the rollers 48a and 48b are moved to the lower surfaces of the claw members 50a and 50b. Can be lifted together with the pressing members 52a and 52b by the lever principle. The long tongue-like claw members 50 a and 50 b are inserted into the long concave portions 22 a and 22 b on the bottom surface of the casing 14. At the same time, short tongue-shaped pressing members 52a and 52b are also inserted into the short recesses 24a and 24b on the upper surface of the casing 14. That is, the casing 14 is moved into the casing 14 while being sandwiched between the long tongue-like claw members 50a and 50b of the attachment / detachment device 30 and the short pressing members 52a and 52b. If the pressing operation on the handle 60 is released, the battery pack P is installed in the casing 14. Then, the attachment / detachment device 30 moves backward so as to pull out the claw members 50a, 50b and the pressing members 52a, 52b. It should be easily understood that when the battery pack P already stored in the casing 14 is taken out, the reverse operation is performed.
[0018]
【The invention's effect】
According to the present invention, since the battery pack can be easily stored and taken out from the electric vehicle, the work can be performed in a very short time and surely. Therefore, maintenance and inspection of the battery pack itself can be simplified.
