本発明は、電気自動車やハイブリッド車両などの電動車両に用いるバッテリ取付け装置、特に、車体の下向き開口付きバッテリ収納空所内に、該下向き開口からバッテリを挿脱して取付けするようにした電動車両のバッテリ取付け装置に関するものである。   The present invention relates to a battery mounting device for use in an electric vehicle such as an electric vehicle or a hybrid vehicle, and more particularly, a battery for an electric vehicle in which a battery is inserted into and removed from a battery housing space with a downward opening of a vehicle body. It relates to a mounting device.

かかる電動車両のバッテリ取付け装置としては、従来から種々のものが提案されており、その一例として、例えば特許文献1に記載のようなものがある。   Various types of battery mounting devices for such electric vehicles have been proposed in the past, and one example is described in Patent Document 1, for example.

このバッテリ取付け装置は、バッテリ載置台を、そのバッテリ取付け範囲が車体の下向き開口付きバッテリ収納空所と整列するよう位置決めし、
この状態でバッテリ載置台上にバッテリ収納空所から空のバッテリを受け取って仮置台に乗せ、
その後、ラックからバッテリ載置台上に充電済バッテリを受け取って、車体のバッテリ収納空所内に下向き開口から挿入し、この挿入状態でバッテリをロックするものである。
特開平０６−２６２９５１号公報 The battery mounting device positions the battery mounting base so that the battery mounting range is aligned with the battery storage space with the downward opening of the vehicle body,

JP-A-06-262951

ところでバッテリは、多数個のバッテリセルを相互に電気接続して一纏めにしたユニットで構成するため、重量が嵩んで非常に重くなることがあり、
上記の取付け作業に当たってこのバッテリをバッテリ載置台上に乗せた時、バッテリ載置台が、数ミリメートル程度ではあるが、撓み変形したり、曲げ変形するのを禁じ得ない。 By the way, since the battery is composed of a unit in which a large number of battery cells are electrically connected to each other, the weight may increase and become very heavy.
When the battery is placed on the battery mounting table during the above-described mounting operation, the battery mounting table is in the order of several millimeters, but it cannot be forbidden to bend or bend.

かようにバッテリ載置台が変形すると、バッテリをバッテリ収納空所内に挿入した時に、バッテリ側のロック部と、バッテリ収納空所側（車体側）ロック部との相対位置が正規の位置からずれてしまい、
バッテリをバッテリ収納空所内（車体）に対しロックすることができず、バッテリが搭載困難になる。 When the battery mounting table is deformed in this way, when the battery is inserted into the battery storage space, the relative position between the battery side lock portion and the battery storage space side (vehicle body side) lock portion is shifted from the normal position. Sisters,
The battery cannot be locked with respect to the inside of the battery storage space (vehicle body), making it difficult to mount the battery.

本発明は、バッテリを乗せるバッテリ載置台が、バッテリの重量により変形しても、上記の問題が生じなくなる程度まで当該変形を低減し得るようにした電動車両のバッテリ取付け装置を提供することを目的とする。   An object of the present invention is to provide a battery mounting device for an electric vehicle that can reduce the deformation to such an extent that the above-mentioned problem does not occur even if the battery mounting table on which the battery is mounted is deformed due to the weight of the battery. And

この目的のため、本発明による電動車両のバッテリ取付け装置は、
車体の下向き開口付きバッテリ収納空所内に、該下向き開口からバッテリを挿脱して取付けするものであることを前提とする。 For this purpose, the battery mounting device for an electric vehicle according to the present invention is:
It is assumed that the battery is inserted and removed from the downward opening in the battery housing space with the downward opening of the vehicle body.

そして本発明は、片持ち梁型式に支持され、上記バッテリ収納空所に対するバッテリの挿脱中バッテリを載置しておくバッテリ載置台に対し、
バッテリ重量によるバッテリ載置台の変形力に抵抗する変形抗力を生じさせる変形抗力発生構造を設け、この変形抗力発生構造を以下のように構成した点に特徴づけられる。
つまり当該変形抗力発生構造は、バッテリ重量によるバッテリ載置台の変形を検知するバッテリ載置台変形検知手段と、該手段により検知したバッテリ載置台の変形を少なくとも小さくするような変形抗力を生じさせる変形抗力発生手段とを具備する。
そして上記バッテリ載置台変形検知手段は、上記バッテリ載置台の片持ち梁型式の支持部と、該支持部から遠いバッテリ載置台の先端縁との間に張設した線状材を具え、該線状材の上記支持部から前記先端縁への繰り出し量を基に上記バッテリ載置台の撓み変形を検知するよう構成したものである。
And this invention is supported by the cantilever type, and for the battery mounting table for mounting the battery during the insertion and removal of the battery with respect to the battery storage space,
A deformation drag generating structure for generating a deformation drag that resists the deformation force of the battery mounting table due to the battery weight is provided , and this deformation drag generation structure is characterized as follows.
That is, the deformation drag generating structure includes a battery mounting table deformation detecting unit that detects deformation of the battery mounting table due to the weight of the battery, and a deformation drag that generates a deformation drag that at least reduces the deformation of the battery mounting table detected by the unit. Generating means.
The battery mounting table deformation detecting means includes a linear member stretched between a cantilever type supporting portion of the battery mounting table and a tip edge of the battery mounting table far from the supporting portion. The bending deformation of the battery mounting table is detected on the basis of the amount of feeding of the shaped material from the support portion to the tip edge .

上記した本発明による電動車両のバッテリ取付け装置にあっては、
変形抗力発生構造を成すバッテリ載置台変形検知手段および変形抗力発生手段のうち、前者のバッテリ載置台変形検知手段がバッテリ重量によるバッテリ載置台の変形を検知し、後者の変形抗力発生手段が当該検知したバッテリ載置台の変形を少なくとも小さくするような変形抗力を生じさせるため、変形抗力発生構造が、バッテリ重量によるバッテリ載置台の変形力に抵抗する変形抗力を生じさせることとなり、
この変形抗力で、バッテリの重量によるバッテリ載置台の変形を低減し得ることとなる。
In the battery mounting device for an electric vehicle according to the present invention described above,
Of the battery mounting table deformation detecting means and the deformation drag generating means forming the deformation drag generating structure, the former battery mounting table deformation detecting means detects the deformation of the battery mounting table due to the weight of the battery, and the latter deformation drag generating means detects the deformation. to produce the modified drag as was the deformation of the battery platform at least reduce, the deformation resistance force generating structure becomes a to cause deformation drag to resist deformation force of the battery platform by the battery weight,

バッテリ載置台の撓み変形量が最も大きな先端縁の変形を検知することとなって、バッテリ載置台の撓み変形量を高感度に、しかも簡単で安価な構成により検知することができる。

Therefore, due to the deformation of the battery mounting table, when the battery is inserted into the battery storage space, the relative position between the battery side lock portion and the battery storage space side (vehicle body side) lock portion is shifted from the normal position. There is no such thing as

以下、本発明の実施の形態を、図面に示す実施例に基づき詳細に説明する。
[第1実施例]
図1は、本発明の第1実施例になる電動車両のバッテリ取付け装置を示し、1は、ハイブリッド車両や電気自動車などの電動車両である。
この電動車両1は、床下に下向き開口付きバッテリ収納空所2を具え、当該空所2内におけるバッテリ（図1では、空所2内に未だバッテリが収納されていない状態を示す）からの電力で駆動されるモータを動力源として具えるものとする。 Hereinafter, embodiments of the present invention will be described in detail based on examples shown in the drawings.
[First embodiment]
FIG. 1 shows a battery mounting device for an electric vehicle according to a first embodiment of the present invention. Reference numeral 1 denotes an electric vehicle such as a hybrid vehicle or an electric vehicle.
This electric vehicle 1 has a battery storage space 2 with a downward opening below the floor, and the electric power from the battery in the space 2 (in FIG. 1, the battery 2 is not yet stored in the space 2). It is assumed that the motor driven by is provided as a power source.

電動車両1は、テーブル3上に乗せた状態でバッテリ取付け作業を自動的に行われるものとする。
テーブル3上には、Y方向（横方向）車体位置調整機構4およびX方向（前後方向）車体位置調整機構5を設け、
これら機構4,5により電動車両1をテーブル3上における正規の位置に位置決めする。
この状態で、テーブル3上に設けた車体床面レベルセンサ6により、水平面に対するバッテリ収納空所2の傾斜を検知する。 It is assumed that the electric vehicle 1 is automatically subjected to the battery mounting operation in a state where it is placed on the table 3.
On the table 3, a Y-direction (lateral direction) vehicle body position adjustment mechanism 4 and an X-direction (front-back direction) vehicle body position adjustment mechanism 5 are provided.
The electric vehicle 1 is positioned at a regular position on the table 3 by these mechanisms 4 and 5.
In this state, the vehicle body floor level sensor 6 provided on the table 3 detects the inclination of the battery storage space 2 with respect to the horizontal plane.

7は交換用バッテリで、この交換用バッテリ7はバッテリ搬送装置8によりバッテリ載置台9上に搬送する。
バッテリ取付けに際しては、バッテリ載置台9をロボット10により、バッテリ載置台9上のバッテリ7が、車体床面レベルセンサ6で検知したバッテリ収納空所2の傾斜と同じ傾斜状態になるよう傾き制御すると共に、バッテリ載置台9上のバッテリ7がバッテリ収納空所2に整列するよう位置決めする。 Reference numeral 7 denotes a replacement battery. The replacement battery 7 is transferred onto the battery mounting table 9 by the battery transfer device 8.
When installing the battery, the robot 10 controls the tilt of the battery mounting table 9 so that the battery 7 on the battery mounting table 9 is in the same tilted state as the tilt of the battery storage space 2 detected by the vehicle body floor level sensor 6. At the same time, the battery 7 on the battery mounting base 9 is positioned so as to align with the battery housing space 2.

その後、バッテリ載置台9をロボット10により矢印で示すように上昇させ、バッテリ載置台9上のバッテリ7をバッテリ収納空所2内にその下向き開口から、バッテリ収納空所2の側面ガイドによる案内下で挿入する。
この挿入後バッテリ7を、バッテリ収納空所2内に保持されるよう、車体に対しロックする。 Thereafter, the battery mounting table 9 is raised by the robot 10 as indicated by the arrow, and the battery 7 on the battery mounting table 9 is guided into the battery storage space 2 from the downward opening thereof by the side guide of the battery storage space 2. Insert with.
After this insertion, the battery 7 is locked to the vehicle body so as to be held in the battery housing space 2.

ところで、バッテリ7は図2に示すように、多数個のバッテリセル7aを相互に電気接続して一纏めにしたユニットで構成するため、重量が嵩んで200kg〜300kgもの重さになることがある。
このため、バッテリ載置台9が図2に示すごとく、基端9aにおいてロボット10（図1参照）に対し片持ち梁型式に支持されている場合につき説明すると、以下のような問題を生ずる。 By the way, as shown in FIG. 2, since the battery 7 is configured by a unit in which a large number of battery cells 7a are electrically connected to each other, the battery 7 may increase in weight and may be as heavy as 200 kg to 300 kg.
For this reason, as shown in FIG. 2, the following problem occurs when the battery mounting table 9 is supported in a cantilever type with respect to the robot 10 (see FIG. 1) at the base end 9a.

つまり、バッテリ取付け作業に当たってバッテリ7をバッテリ載置台9上に乗せた時、バッテリ載置台9はバッテリ7を乗せる前の図2(a)に示す状態から、バッテリ重量による同図(b)に示す下向き変形力F1によって、先端縁9bが5〜7mm程度下降して、撓み変形するのを禁じ得ない。   That is, when the battery 7 is placed on the battery mounting base 9 during the battery mounting operation, the battery mounting base 9 is shown in FIG. 2 (b) by the battery weight from the state shown in FIG. Due to the downward deformation force F1, the tip edge 9b cannot be prevented from being bent and deformed by about 5 to 7 mm.

かようにバッテリ載置台9が変形すると、バッテリ取付け作業時にバッテリ7がバッテリ収納空所2（図1参照）の周壁ガイド部に噛み込んだり、引っかかり、
バッテリ7を、空になってバッテリ収納空所2から取り出そうとする時に、バッテリ7をバッテリ収納空所2から取り外すことができなくなる懸念がある。 When the battery mounting table 9 is deformed in this way, the battery 7 is caught or caught in the peripheral wall guide part of the battery storage space 2 (see FIG. 1) during the battery mounting operation.
There is a concern that the battery 7 cannot be removed from the battery storage space 2 when the battery 7 becomes empty and is taken out of the battery storage space 2.

また、バッテリ載置台9が図2(b)につき上記したように変形すると、バッテリ7をバッテリ収納空所2内に挿入した時に、バッテリ側のロック部（図示せず）と、バッテリ収納空所側（車体側）ロック部（同じく図示せず）との相対位置が正規の位置からずれてしまい、
バッテリ7をバッテリ収納空所2内に挿入後、車体に対しロックすることができず、バッテリ7が搭載困難になるという懸念も払拭しきれない。 Further, when the battery mounting table 9 is deformed as described above with reference to FIG. 2 (b), when the battery 7 is inserted into the battery storage space 2, the battery side lock portion (not shown) and the battery storage space The relative position with the side (vehicle body side) lock part (also not shown) deviates from the normal position,
After the battery 7 is inserted into the battery housing space 2, it cannot be locked to the vehicle body, and the concern that it becomes difficult to mount the battery 7 cannot be eliminated.

[変形抗力発生構造]
そこで本実施例（第1実施例）においては、バッテリ載置台9が、バッテリ7の重量により変形しても、この変形を無くし得るように、若しくは少なくとも上記の問題が生じなくなる程度まで当該変形を低減し得るようになす、以下のごとき変形抗力発生構造を付加する。 [Deformation drag generation structure]
Therefore, in this embodiment (first embodiment), even if the battery mounting table 9 is deformed due to the weight of the battery 7, the deformation is made so that the deformation can be eliminated, or at least to the extent that the above problem does not occur. A deformation drag generating structure such as the following, which can be reduced, is added.

この変形抗力発生構造を詳述するに、片持ち梁型式に支持したバッテリ載置台9の支持基端9aと、この支持基端9aから遠いバッテリ載置台9の先端縁9bとの間に、図3(a)に示すごとくワイヤなどの非伸縮線状材11を張設する。
この非伸縮線状材11は、その先端11aをバッテリ載置台9の先端縁9bに係着し、他端11bを、バッテリ載置台9の支持基端9aに設けたガイドローラ12により案内しつつ、モータ13の出力軸に固設した端末ローラ14の外周に係着する。 To describe this deformation drag generation structure in detail, a figure is provided between the supporting base end 9a of the battery mounting base 9 supported in a cantilever type and the leading edge 9b of the battery mounting base 9 far from the supporting base end 9a. As shown in 3 (a), a non-stretchable linear material 11 such as a wire is stretched.
The non-stretchable linear material 11 has its tip 11a engaged with the tip edge 9b of the battery mounting table 9, and the other end 11b guided by a guide roller 12 provided on the support base end 9a of the battery mounting table 9. The terminal roller 14 fixed to the output shaft of the motor 13 is engaged with the outer periphery.

モータ13は、非伸縮線状材11に所定の張力が付与されるよう端末ローラ14を附勢するモータとし、かかる非伸縮線状材11の張設状態を保つようモータ13は端末ローラ14を両方向へ回転位置制御可能なものとする。
そして、図3(a)に示すバッテリ非搭載時におけるガイドローラ12の回転位置を基準とし、この基準位置からのガイドローラ12の回転量を検知する回転センサ15を設ける。 The motor 13 is a motor that urges the terminal roller 14 so that a predetermined tension is applied to the non-stretchable linear material 11, and the motor 13 causes the terminal roller 14 to maintain the stretched state of the non-stretchable linear material 11. The rotational position can be controlled in both directions.
A rotation sensor 15 for detecting the rotation amount of the guide roller 12 from the reference position is provided based on the rotation position of the guide roller 12 when the battery is not mounted as shown in FIG.

バッテリ載置台9上にバッテリ7を乗せる前は、バッテリ載置台9がバッテリ重量を受けないため、図3(a)に示すように真っ直ぐな状態であり、ガイドローラ12の回転位置は基準位置に保たれる。
このとき回転センサ15は、ガイドローラ12の基準位置からの回転が0であるのを検出しており、これをもって、バッテリ載置台9がバッテリ荷重に伴う変形を生じていないと判定し得る。 Before placing the battery 7 on the battery mounting base 9, the battery mounting base 9 does not receive the weight of the battery, so it is in a straight state as shown in Fig. 3 (a), and the rotation position of the guide roller 12 is at the reference position. Kept.
At this time, the rotation sensor 15 detects that the rotation of the guide roller 12 from the reference position is zero, and with this, it can be determined that the battery mounting table 9 is not deformed due to the battery load.

図3(b)に示すようにバッテリ載置台9上にバッテリ7を乗せると、バッテリ載置台9はバッテリ重量による下向き変形力F1を受けて、
図3(a)に示す真直状態から、同図(b)に示すように、支持基端9aを支点とする撓み変形される。
かかるバッテリ載置台9の撓み変形により、非伸縮線状材11の先端11aは非伸縮線状材11を、バッテリ載置台9の支持基端9aから先端縁9bに向かう方向へ繰り出させることとなる。 As shown in FIG. 3 (b), when the battery 7 is placed on the battery mounting table 9, the battery mounting table 9 receives the downward deformation force F1 due to the battery weight,
From the straight state shown in FIG. 3 (a), as shown in FIG. 3 (b), bending deformation is performed with the support base end 9a as a fulcrum.
By such bending deformation of the battery mounting table 9, the tip 11a of the non-stretchable linear material 11 causes the non-stretchable linear material 11 to be fed out in the direction from the support base end 9a of the battery mounting table 9 toward the tip edge 9b. .

かかる非伸縮線状材11の繰り出しは、非伸縮線状材11を案内しているガイドローラ12の対応方向（図3の時計方向）への回転を生起させ、当該ガイドローラ12の回転量（非伸縮線状材11の繰り出し量）がバッテリ載置台9の撓み変形量に対応する。
よって、当該ガイドローラ12の回転量を検出する回転センサ15の検出値からバッテリ載置台9の撓み変形量を判定することができる。
従って非伸縮線状材11は、回転センサ15と共に、本発明におけるバッテリ載置台変形検知手段に相当する。 The unwinding of the non-stretchable linear material 11 causes the guide roller 12 guiding the non-stretchable linear material 11 to rotate in the corresponding direction (clockwise in FIG. 3), and the rotation amount of the guide roller 12 ( The feed amount of the non-stretchable linear material 11) corresponds to the bending deformation amount of the battery mounting table 9.
Therefore, the amount of bending deformation of the battery mounting base 9 can be determined from the detection value of the rotation sensor 15 that detects the rotation amount of the guide roller 12.
Therefore, the non-stretchable linear material 11 together with the rotation sensor 15 corresponds to the battery mounting table deformation detecting means in the present invention.

かかるバッテリ載置台9の撓み変形時は図3(c)に示すごとく、上記非伸縮線状材11の繰り出し量に相当する長さだけ非伸縮線状材11を手繰り戻すよう、モータ13により端末ローラ14を回転駆動させ、ガイドローラ12を図3(a)の基準位置に回転復帰させる。
この間、非伸縮線状材11の先端11aは、これが係着されているバッテリ載置台9の先端縁9bに対し、図3(b)に示す下向き変形力F1と逆向きの変形抗力F2を生じさせ、
図3(b)に示すバッテリ載置台9の変形を、図3(c)に示すようになくすか、または少なくとも小さくすることができる。
従ってモータ13および端末ローラ14は、非伸縮線状材11と共に、本発明における変形抗力発生手段に相当する。 When the battery mounting table 9 is bent and deformed, as shown in FIG. 3 (c), the terminal is driven by the motor 13 so that the non-stretchable linear material 11 is rewinded by a length corresponding to the feed amount of the non-stretchable linear material 11. The roller 14 is rotated and the guide roller 12 is rotated and returned to the reference position shown in FIG.
During this time, the tip 11a of the non-stretchable linear material 11 generates a deformation resistance F2 opposite to the downward deformation force F1 shown in FIG. 3 (b) against the tip edge 9b of the battery mounting table 9 to which the non-stretchable linear material 11 is attached. Let
The deformation of the battery mounting table 9 shown in FIG. 3 (b) can be eliminated or at least made small as shown in FIG. 3 (c).
Therefore, the motor 13 and the terminal roller 14 together with the non-stretchable linear material 11 correspond to the deformation drag generating means in the present invention.

[作用効果]
上記した第1実施例になる電動車両のバッテリ取付け装置にあっては、
バッテリ載置台9の片持ち梁支持基端9aと、この基端9aから遠いバッテリ載置台9の先端縁9bとの間に張設した非伸縮線状材11の基端9aから先端縁9bへの繰り出し量を基にバッテリ載置台9の撓み変形量を検知し、
非伸縮線状材11を上記の繰り出し量に相当する長さだけ、モータ13および端末ローラ14により手繰り戻して、バッテリ重量によるバッテリ載置台9の変形力F1に抵抗する変形抗力F2を生じさせるため、
この変形抗力F2で、バッテリ7の重量によるバッテリ載置台9の変形を無くし得るか、少なくとも低減し得ることとなる。 [Effect]
In the battery mounting device of the electric vehicle according to the first embodiment described above,
From the base end 9a of the non-stretchable linear material 11 stretched between the cantilever support base end 9a of the battery mounting base 9 and the front end edge 9b of the battery mounting base 9 far from the base end 9a to the front end edge 9b The amount of bending deformation of the battery mounting base 9 is detected based on the amount of
In order to generate a deformation drag F2 that resists the deformation force F1 of the battery mounting table 9 due to the weight of the battery by hand-retracting the non-stretchable linear material 11 by the motor 13 and the terminal roller 14 by a length corresponding to the above-mentioned feeding amount. ,
With this deformation resistance F2, the deformation of the battery mounting table 9 due to the weight of the battery 7 can be eliminated or at least reduced.

従って、バッテリ載置台9の変形に起因して、バッテリ取付け作業時にバッテリ7がバッテリ収納空所2の周壁ガイド部に噛み込んだり、引っかかるようなことがなくなり、
バッテリ7を、空になってバッテリ収納空所2から取り出そうとする時に、バッテリ7をバッテリ収納空所2から取り外すことができなくなる懸念を払拭することができる。 Therefore, due to the deformation of the battery mounting table 9, the battery 7 does not bite or get caught in the peripheral wall guide part of the battery housing space 2 during the battery mounting operation,
The concern that the battery 7 cannot be removed from the battery housing space 2 when the battery 7 is empty and is taken out from the battery housing space 2 can be eliminated.

また、バッテリ載置台9の変形に起因して、バッテリ7をバッテリ収納空所2内に挿入した時に、バッテリ側のロック部（図示せず）と、バッテリ収納空所側（車体側）ロック部（同じく図示せず）との相対位置が正規の位置からずれてしまうようなこともなくなり、
バッテリ7をバッテリ収納空所2内（車体）に対しロックすることができず、バッテリ7が搭載困難になるという懸念も払拭することができる。 When the battery 7 is inserted into the battery storage space 2 due to the deformation of the battery mounting table 9, the battery side lock portion (not shown) and the battery storage space side (vehicle body side) lock portion (Also not shown) the relative position with respect to the regular position is no longer shifted,
The concern that the battery 7 cannot be locked with respect to the inside (vehicle body) of the battery housing space 2 and the battery 7 becomes difficult to mount can be eliminated.

なお、バッテリ載置台9の撓み変形量を検知するに際し、バッテリ載置台9の片持ち梁支持基端9aと、この基端9aから遠いバッテリ載置台9の先端縁9bとの間に張設した非伸縮線状材11の基端9aから先端縁9bへの繰り出し量を基に当該検知を行うため、
バッテリ載置台9の撓み変形量が最も大きな先端縁9bの変形を検知することとなって、バッテリ載置台9の撓み変形量を高感度に、しかも簡単で安価な構成により検知することができる。 When detecting the amount of bending deformation of the battery mounting table 9, it was stretched between the cantilever support base end 9a of the battery mounting table 9 and the tip edge 9b of the battery mounting table 9 far from the base end 9a. In order to perform the detection based on the feed amount from the base end 9a to the front end edge 9b of the non-stretchable linear material 11,
Since the deformation of the tip edge 9b having the largest amount of deformation of the battery mounting table 9 is detected, the amount of bending deformation of the battery mounting table 9 can be detected with high sensitivity and with a simple and inexpensive configuration.

また、バッテリ重量によるバッテリ載置台9の変形力F1に抵抗する変形抗力F2を生じさせるに際し、上記の非伸縮線状材11を上記繰り出し量に相当する長さだけ、モータ13および端末ローラ14により手繰り戻すことにより変形抗力F2を生じさせるため、
バッテリ載置台9の撓み変形量が予定通り0にされたり、低減されるような変形抗力F2を正確に発生させることができる。 Further, when generating the deformation drag F2 that resists the deformation force F1 of the battery mounting table 9 due to the battery weight, the non-stretchable linear material 11 is moved by the motor 13 and the terminal roller 14 by a length corresponding to the feed amount. In order to generate deformation drag F2 by rewinding,
It is possible to accurately generate the deformation drag F2 such that the deformation amount of the battery mounting table 9 is reduced to zero or reduced as planned.

[第2実施例]
ところで、図3に示す第1実施例によりバッテリ載置台9の撓み変形に関した問題を解消したとしても、
バッテリ7の更なる重量増や、セル配置の違いなどにより、図4(a)に矢印で示す変形力F3により、バッテリ載置台9が片持ち梁支持基端9aおよび先端縁9b間において、例えば2〜4mm程度下降する曲げ変形を生ずることがある。 [Second Example]
By the way, even if the problem relating to the bending deformation of the battery mounting table 9 is solved by the first embodiment shown in FIG.
Due to the further weight increase of the battery 7, the difference in cell arrangement, etc., the battery mounting base 9 is placed between the cantilever support base end 9a and the front end edge 9b by the deformation force F3 indicated by the arrow in FIG. It may cause bending deformation that descends about 2-4mm.

かかるバッテリ載置台9の両端間曲げ（湾曲）変形によっても、バッテリ取付け作業時にバッテリ7がバッテリ収納空所2（図1参照）の周壁ガイド部に噛み込んだり、引っかかり、バッテリ7をバッテリ収納空所2から取り外すことができなくなるという問題や、
バッテリ7をバッテリ収納空所2内に挿入した時に、バッテリ側ロック部およびバッテリ収納空所側（車体側）ロック部の相互係合ができずに、バッテリ7が搭載困難になるという問題を生ずる。 Even when the battery mounting table 9 is bent (curved) between both ends, the battery 7 is caught or caught in the peripheral wall guide portion of the battery storage space 2 (see FIG. 1) during the battery mounting operation, and the battery 7 is empty. The problem of being unable to remove from location 2,
When the battery 7 is inserted into the battery storage space 2, the battery side lock part and the battery storage space side (vehicle body side) lock part cannot be engaged with each other, causing a problem that the battery 7 is difficult to mount. .

そこで本実施例（第2実施例）は、かかるバッテリ載置台9の両端間曲げ（湾曲）変形をも解消または軽減し得るようにしたものである。
このため図4(a)に示すごとく、バッテリ載置台9の下方にあって該バッテリ載置台9との間の距離を検出する複数個（図示例では5個）のレーザ変位計などの距離センサ20-1〜20-5を設ける。
これら距離センサ20-1〜20-5は、バッテリ載置台9の片持ち梁支持基端9aおよび先端縁9b間に順次、等間隔に配列し、これら距離センサ20-1〜20-5により検出した距離の変化からバッテリ載置台9の上記曲げ変形を検知する。
従って距離センサ20-1〜20-5は、本発明におけるバッテリ載置台変形検知手段に相当する。 In this embodiment (second embodiment), the bending (curving) deformation between both ends of the battery mounting table 9 can be eliminated or reduced.
Therefore, as shown in FIG. 4 (a), a distance sensor such as a plurality of (five in the illustrated example) laser displacement gauges that are below the battery mounting table 9 and detect the distance to the battery mounting table 9. 20-1 to 20-5 are provided.
These distance sensors 20-1 to 20-5 are sequentially arranged at equal intervals between the cantilever supporting base end 9a and the distal end edge 9b of the battery mounting base 9, and are detected by these distance sensors 20-1 to 20-5. The bending deformation of the battery mounting table 9 is detected from the change in the measured distance.
Therefore, the distance sensors 20-1 to 20-5 correspond to the battery mounting table deformation detecting means in the present invention.

そして、距離センサ20-1〜20-5からの距離情報に基づき検知したバッテリ載置台9の曲げ変形から、バッテリ載置台9に乗っているバッテリ7の仕様を特定し、
当該特定仕様のバッテリ7に対応する矯正ブロック21を、図4(b)に示すごとくバッテリ載置台9の下面に着脱自在に取り付ける。 And, from the bending deformation of the battery mounting table 9 detected based on the distance information from the distance sensors 20-1 to 20-5, the specification of the battery 7 riding on the battery mounting table 9 is specified,
The correction block 21 corresponding to the battery 7 of the specific specification is detachably attached to the lower surface of the battery mounting base 9 as shown in FIG. 4 (b).

ここで矯正ブロック21は、バッテリ7の仕様が1種類のみである場合、1種類の矯正ブロック21をバッテリ載置台9の下面に取り付けっぱなしにするが、
バッテリ7の仕様が複数種類ある場合、図4(b)に矯正ブロック21-1および矯正ブロック21-2により示すごとく、バッテリ仕様の数と同数の種類のものを予め用意しておく。 Here, when the specification of the battery 7 is only one type, the correction block 21 is left attached to the lower surface of the battery mounting base 9 with one type of correction block 21,
When there are a plurality of types of specifications of the battery 7, as shown by the correction blocks 21-1 and 21-2 in FIG. 4 (b), the same number of types as the number of battery specifications is prepared in advance.

しかし何れにしても、1種類の矯正ブロック21、各種の矯正ブロック21-1および矯正ブロック21-2はそれぞれ、対応する仕様のバッテリ7がバッテリ載置台9に付与する図4(a)に示した曲げ変形力F3を打ち消すような逆向きの変形抗力を、バッテリ載置台9の下面から上向きに作用させて、バッテリ載置台9の曲げ変形を無くしたり、軽減するものとする。   In any case, however, one type of straightening block 21, various straightening blocks 21-1 and straightening block 21-2 are shown in FIG. The bending deformation force of the reverse direction that cancels the bending deformation force F3 is applied upward from the lower surface of the battery mounting table 9, so that the bending deformation of the battery mounting table 9 is eliminated or reduced.

かかる本実施例（第2実施例）の構成によれば、第1実施例と同様にバッテリ載置台9の撓み変形に関する問題を解消し得て、第1実施例と同様な作用効果を奏し得るのに加え、
バッテリ載置台9の両端間曲げ（湾曲）変形をも解消または軽減し得て、これに関する問題解決をも実現することができる。 According to the configuration of the present embodiment (second embodiment), the problem related to the bending deformation of the battery mounting table 9 can be solved similarly to the first embodiment, and the same effect as the first embodiment can be obtained. In addition to
The bending (curving) deformation between the both ends of the battery mounting table 9 can also be eliminated or reduced, and a solution to this problem can also be realized.

なお、バッテリ載置台9の支持基端9aおよび先端縁9b間の曲げ変形を検知するに際し、
バッテリ載置台9の下方でその支持基端9aおよび先端縁9b間に等間隔に配列した距離センサ20-1〜20-5により、バッテリ載置台9の下面との間における距離を検出して、当該検出距離の変化からバッテリ載置台9の上記曲げ変形を検知するため、
当該バッテリ載置台9の曲げ変形検知を、簡単で安価な構成により行うことがでできる。 In detecting the bending deformation between the support base end 9a and the front end edge 9b of the battery mounting table 9,
The distance between the bottom surface of the battery mounting table 9 is detected by the distance sensors 20-1 to 20-5 arranged at equal intervals between the supporting base end 9a and the front end edge 9b below the battery mounting table 9. In order to detect the bending deformation of the battery mounting base 9 from the change in the detection distance,
The bending deformation of the battery mounting table 9 can be detected with a simple and inexpensive configuration.

[第3実施例]
ところで、図4に示す第2実施例においては、バッテリ載置台9に乗せるバッテリ7の仕様が変化する度に、バッテリ載置台9の下面へ着脱自在に取り付けた矯正ブロック21を交換する面倒な作業が必要である。
第3実施例は、この面倒を解消し得るよう、バッテリ載置台9に乗せるバッテリ7の仕様が変化しても、バッテリ載置台9の曲げ変形を自動的に無くしたり、軽減し得るようにしたものである。 [Third embodiment]
By the way, in the second embodiment shown in FIG. 4, every time the specification of the battery 7 to be placed on the battery mounting table 9 changes, the troublesome work of replacing the correction block 21 detachably attached to the lower surface of the battery mounting table 9 is necessary.
In the third embodiment, in order to eliminate this trouble, the bending deformation of the battery mounting table 9 can be automatically eliminated or reduced even if the specifications of the battery 7 mounted on the battery mounting table 9 change. Is.

このため本実施例（第3実施例）においては、図5に示すごとくバッテリ載置台9の下方に配してボールネジ31を設け、
このボールネジ31は、バッテリ載置台9の基端9aおよび先端縁9b間に延在するよう、また、バッテリ載置台9の下面に平行に延在するよう配置し、バッテリ載置台9に回転自在に支持する。 For this reason, in this embodiment (third embodiment), a ball screw 31 is provided below the battery mounting base 9 as shown in FIG.
The ball screw 31 is disposed so as to extend between the base end 9a and the distal end edge 9b of the battery mounting table 9, and so as to extend in parallel with the lower surface of the battery mounting table 9, and is freely rotatable on the battery mounting table 9. To support.

ボールネジ31は図6に明示するごとく、バッテリ載置台9の基端9aおよび先端縁9b間の中間地点直下の中央部を境に、両側でネジの向きを相互逆向きとなし、
これら逆向きネジ部にそれぞれ、ボールナット32,33を介して変形抗力発生ブロック34,35を螺合させる。
変形抗力発生ブロック34,35はそれぞれ、図5,6の下面を平坦とし、これら平坦面をバッテリ載置台9の対応する平坦面に接触させて廻り止めする。 As clearly shown in FIG. 6, the ball screw 31 has the screw direction opposite to each other on both sides, with the central portion immediately below the intermediate point between the base end 9a and the tip edge 9b of the battery mounting base 9 as shown in FIG.
The deformation force generation blocks 34 and 35 are screwed into the reversely threaded portions via ball nuts 32 and 33, respectively.
The deformation drag generation blocks 34 and 35 are flattened on the lower surfaces of FIGS. 5 and 6, respectively, and the flat surfaces are brought into contact with the corresponding flat surfaces of the battery mounting table 9 and are prevented from rotating.

ボールネジ31の一端に、バッテリ載置台9上に設けたモータ36を結合し、これによりボールネジ31を何れか一方向へ回転可能とする。
モータ36によるボールネジ31の回転制御は、図4(a)におけると同様な距離センサ20-1〜20-5からの信号に応答させて、以下のように当該回転制御を行うものとする。 A motor 36 provided on the battery mounting base 9 is coupled to one end of the ball screw 31 so that the ball screw 31 can be rotated in any one direction.
The rotation control of the ball screw 31 by the motor 36 is performed in the following manner in response to signals from the distance sensors 20-1 to 20-5 similar to those in FIG.

バッテリ7の重量に伴う図5に矢印で示す変形力F3により、バッテリ載置台9が片持ち梁支持基端9aおよび先端縁9b間において曲げ変形したとき、
距離センサ20-1〜20-5からの距離情報に基づき当該バッテリ載置台9の曲げ変形を判定し、この曲げ変形をなくすか、または、問題とならない程度まで小さくするのに必要な変形抗力発生ブロック34,35の相互接近位置を演算する。 When the battery mounting table 9 is bent and deformed between the cantilever support base end 9a and the front end edge 9b by the deformation force F3 indicated by the arrow in FIG. 5 due to the weight of the battery 7,
Based on the distance information from the distance sensors 20-1 to 20-5, the bending deformation of the battery mounting base 9 is judged, and the deformation drag necessary for eliminating the bending deformation or reducing it to a level that does not cause a problem is generated. The mutual approach positions of the blocks 34 and 35 are calculated.

そして、かようにして演算した変形抗力発生ブロック34,35の相互接近位置を実現するためのボールネジ31の回転方向および回転量を求め、これらが実現されるようモータ36を回転制御する。
当該モータ36を回転制御で変形抗力発生ブロック34,35は、上記演算結果の通りとなるよう相互に接近する。 Then, the rotation direction and the rotation amount of the ball screw 31 for realizing the mutual approach positions of the deformation drag generating blocks 34 and 35 calculated in this way are obtained, and the motor 36 is rotationally controlled so that these are realized.
By controlling the rotation of the motor 36, the deformation drag generating blocks 34 and 35 approach each other so that the result of the above calculation is obtained.

変形抗力発生ブロック34,35は、かかる相互接近により、図6に示すごとくバッテリ載置台9の下面9cに対し、変形力F3と逆向きの変形抗力F4を付与する。
これにより、変形抗力発生ブロック34,35はそれぞれ、バッテリ載置台9の下面9cを図6の破線で示す湾曲状態から実線で示す真直状態へと押し上げ、バッテリ載置台9の曲げ変形をなくすか、または、問題とならない程度まで小さくすることができる。
従って変形抗力発生ブロック34,35は、ボールネジ31、ボールナット32,33およびモータ36と共に、本発明における変形抗力発生手段に相当する。 Due to the mutual approach, the deformation drag generation blocks 34 and 35 apply a deformation drag F4 opposite to the deformation force F3 to the lower surface 9c of the battery mounting base 9 as shown in FIG.
Thereby, each of the deformation drag generation blocks 34, 35 pushes up the lower surface 9c of the battery mounting table 9 from the curved state shown by the broken line in FIG. 6 to the straight state shown by the solid line, and eliminates the bending deformation of the battery mounting table 9. Alternatively, the size can be reduced to a level that does not cause a problem.
Therefore, the deformation drag generation blocks 34 and 35 together with the ball screw 31, the ball nuts 32 and 33, and the motor 36 correspond to the deformation drag generation means in the present invention.

かかる本実施例（第3実施例）の構成によれば、第1実施例と同様な作用効果を奏し得ると共に、
バッテリ載置台9の両端間曲げ（湾曲）変形をも解消または軽減し得て、第2実施例と同様な作用効果を奏し得るのに加え、
第2実施例におけるように、矯正ブロック21の面倒な交換作業を要することなく自動的に、バッテリ載置台9の曲げ変形を自動的に無くしたり、軽減し得るという作用効果を達成することができる。 According to the configuration of the present embodiment (third embodiment), the same operational effects as the first embodiment can be obtained,
In addition to being able to eliminate or reduce the bending (curving) deformation between both ends of the battery mounting table 9, in addition to being able to achieve the same effects as the second embodiment,
As in the second embodiment, it is possible to automatically eliminate the bending deformation of the battery mounting base 9 without requiring a troublesome replacement work of the correction block 21, and to achieve the effect of being able to reduce. .

なお、バッテリ載置台9の下面9cに変形抗力F4を付与して、バッテリ載置台9の曲げ変形をなくすか、または、問題とならない程度まで小さくするに際し、
一対1組の変形抗力発生ブロック34,35を、共通なボールネジ31の一方向回転により相互接近させて作用を行わせる構成としたため、
変形抗力F4がバッテリ載置台9の下面9cにバランス良く付与されることとなり、上記の作用効果を一層顕著なものにすることができる。 In addition, when the deformation resistance F4 is applied to the lower surface 9c of the battery mounting table 9 to eliminate the bending deformation of the battery mounting table 9, or to the extent that does not cause a problem,
Since the pair of deformation drag generating blocks 34, 35 are configured to perform an action by making them approach each other by one-way rotation of a common ball screw 31,
The deformation drag F4 is applied to the lower surface 9c of the battery mounting table 9 in a well-balanced manner, so that the above-described effects can be made more remarkable.

[第4実施例]
ところで、第3実施例においては変形抗力発生ブロック34,35がバッテリ載置台9の下面9cに対し摩擦接触するため、両者の摩耗が大きいと共にモータ36の要求駆動力が大きくなるという問題を生ずる。
この問題解決のため本実施例（第4実施例）においては、図7に示すごとく、バッテリ載置台9の下面9cと変形抗力発生ブロック34,35とが転がり接触となるよう、
バッテリ載置台9の下面9cと接する変形抗力発生ブロック34,35の箇所にそれぞれ、コロ41,42を設け、これらコロ41,42をそれぞれ、軸43,44で変形抗力発生ブロック34,35に対し回転自在に支持する。 [Fourth embodiment]
By the way, in the third embodiment, since the deformation drag generating blocks 34 and 35 are in frictional contact with the lower surface 9c of the battery mounting base 9, there is a problem in that both wear is large and the required driving force of the motor 36 is increased.
In order to solve this problem, in this embodiment (fourth embodiment), as shown in FIG. 7, the lower surface 9c of the battery mounting table 9 and the deformation drag generating blocks 34 and 35 are in rolling contact.
Rollers 41 and 42 are provided at the positions of the deformation drag generation blocks 34 and 35 in contact with the lower surface 9c of the battery mounting base 9, respectively.The rollers 41 and 42 are respectively connected to the deformation drag generation blocks 34 and 35 by the shafts 43 and 44. Support for rotation.

かかる本実施例（第4実施例）の構成によれば、第3実施例の作用効果に加えて、
バッテリ載置台9の両端間曲げ（湾曲）変形を矯正している間に変形抗力発生ブロック34,35がバッテリ載置台9の下面9cに対し転がり接触するため、両者の摩耗を軽減し得ると共にモータ36の要求駆動力を低下させ得るという作用効果を奏することができる。 According to the configuration of this embodiment (fourth embodiment), in addition to the effects of the third embodiment,
Since the deformation drag generating blocks 34 and 35 are in rolling contact with the lower surface 9c of the battery mounting base 9 while correcting the bending (curving) deformation between both ends of the battery mounting base 9, it is possible to reduce both wear and reduce the motor. It is possible to achieve the effect that the required driving force of 36 can be reduced.
