【発明の属する技術分野】
この発明は、フォークリフト等の電気車における駆動用バッテリのカバーを固定するバッテリのカバー固定構造に関する。
【０００２】
【従来の技術】
電気車であるカウンタバランス型フォークリフトでは、図６に示すように、オペレータ用座席シート１の下部に駆動用バッテリが収容されている。このとき、図７に示すように、複数個のバッテリセル２が縦横に配列され、これら各セル２が導電接続体３により直列に接続されてバッテリ４が構成され、一対の引出ケーブル５ａ、５ｂにより外部負荷に接続されるようになっている。
【０００３】
そして、このようなバッテリは、従来図８に示すように、筐体状のバッテリケース６内に収容され、バッテリケース６の開口した上面が、蝶番等により回転可能に設けられたバッテリカバー７によって開閉自在に閉塞され、固定部材によりバッテリカバー７が閉塞状態に保持されており、このバッテリカバー７上に座席シート１が着脱自在に装着される。
【０００４】
ところで、上記したカウンタバランス型フォークリフトが防爆仕様である場合、労働省産業安全研究所による産業安全研究所技術指針における工場電気設備防爆指針に規定されているように、バッテリカバー７を閉塞状態に保持する固定部材の固定用のビス類は錠締め構造、つまりドライバ等の一般的な工具以外の特殊な工具でのみ操作される構造であって、例えば六角ボルトや六角穴付ボルトなどの挿通孔の周囲に環状凸部或いは挿通孔の両側に壁状凸部を有する構造の固定具で固定しなければならず、従来、図８に示すような構成の固定部材９が採用されている。
【０００５】
即ち、図８に示すように、バッテリケース６が載置されているフォークリフトのフレーム１０に支持板１１をボルト等によって固着し、支持板１１に蝶番１２により締結板１３の下端部を回転自在に連結し、このときバッテリケース６の前面に締結板１３が沿うように支持板１１及び締結板１３を配設する。
【０００６】
更に、バッテリカバー７の前面ほぼ中央に連結板１４の上部を固着し、この連結板１４には２個の雌ねじを形成し、バッテリカバー７の閉塞時に締結板１３の上端が連結板１４の下部前側に重なるように締結板１３及び連結板１４の長さや位置を設定しておき、締結板１３の上端部であって連結板１４の両雌ねじに重なる位置に２個のボルト挿通孔１５を形成し、両ボルト挿通孔１５にボルト１６をそれぞれ挿通して連結板１４の雌ねじに螺合し、締結板１３を連結板１４に締結してバッテリカバー７を固定している。このとき、図９に示すように、ボルト挿通孔１５の周囲に環状凸部１７が一体形成され、或いは図１０に示すように、ボルト挿通孔１５の両側に壁状凸部１８が溶接により形成され、錠締め構造が実現されている。
【０００７】
【発明が解決しようとする課題】
しかし、上記した従来のバッテリカバー固定構造の場合、加工誤差や取り付け時の寸法誤差が原因で、締結板１３の両ボルト挿通孔１５と連結板１４の雌ねじとを位置合わせすることが非常に困難であり、ボルト１６の雌ねじへの螺合を容易に行うことができず、バッテリカバー７の固定作業の効率低下を招くという問題があった。
【０００８】
この発明が解決しようとする課題は、バッテリカバーの固定作業の簡素化を図れるようにすることにある。
【０００９】
【課題を解決するための手段】
上記した課題を解決するために、本発明は、縦横に配列された複数のセルから成るバッテリを収容したバッテリケースの上面を開閉自在に閉塞するバッテリカバーを固定するバッテリのカバー固定構造において、前記バッテリカバーまたは前記バッテリケースの一方の前面に固定された鉤状部材と、前記バッテリカバーまたは前記バッテリケースの他方の前面に取り付けられて前記鉤状部材に係脱自在に係止する係止部材と、前記バッテリカバーまたは前記バッテリケースの他方の前面に設けられ前記係止部材が前記鉤状部材に係止した状態に前記係止部材を保持する保持部材と、前記保持部材を前記バッテリカバーまたは前記バッテリケースの他方の前面に固定する固定具とを備えていることを特徴としている。
【００１０】
このように構成すれば、係止部材が鉤状部材に係止され、保持部材によりその係止状態が保持されると共に、固定具により保持部材が固定される。
【００１１】
そのため、各部材の加工誤差や取り付け時の寸法誤差が多少あっても、係止部材と鉤状部材との係止部分でこれらの誤差を吸収することができるため、従来のようなボルト挿通孔の位置合わせが困難になるといった不都合が生じることもなく、係止部材を鉤状部材に係止することが可能になり、バッテリカバーの固定作業の簡素化を図ることができる。
【００１２】
また、本発明は、前記係止部材が、前記バッテリカバーまたは前記バッテリケースの他方の前面に一端側の支持点において回転自在に支持された基体と、一端が前記基体に回転自在に取り付けられて前記基体の回転時に他端が前記鉤状部材に係止する係止体とから成り、前記係止体が前記鉤状部材に係止した状態で前記基体の他端側が回転されたときに、前記係止体が前記基体により引っ張られて前記鉤状部材に係止した状態に維持されることを特徴としている。
【００１３】
こうすれば、係止部材の係止体を鉤状部材に係止し、基体を回転することで係止体を引っ張るようにして係止体を鉤状部材に係止した状態に維持することができ、非常に簡単な操作によってバッテリカバーを固定することが可能になる。
【００１４】
また、本発明は、前記保持部材は、その一端が前記基体の他端部に固着され、その他端部が前記固定具により固定されることを特徴としている。
【００１５】
また、本発明は、前記保持部材は、その一端部が前記バッテリカバーまたは前記バッテリケースの他方の前面に回転自在に取り付けられ、その他端部が前記固定具により固定されることを特徴としている。
【００１６】
このようにすると、保持部材の他端部を固定具により固定するだけで、係止部材を鉤状部材への係止状態を容易に保持することができる。
【００１７】
また、本発明は、前記固定具が、防爆用の錠締め構造を有することを特徴としている。こうすることで、バッテリが、例えば防爆仕様の電気車の駆動用に用いられる場合であっても、バッテリカバーの固定作業を非常に効率的に行うことができる。
【００１８】
【発明の実施の形態】
この発明を防爆仕様のカウンタバランス型フォークリフトの駆動用バッテリに適用した場合の一実施形態について、図１ないし図４を参照して説明する。但し、図１は使用状態における斜視図、図２は一部の分解斜視図、図３は一部の正面図、図４は一部の右側面図である。尚、本実施形態におけるバッテリ収容部分の構成は、上記した図６ないし図１０に示すものと同様であるため、以下の説明ではこれらの図も参照する。
【００１９】
図１ないし図４に示すように、バッテリカバー７の前面ほぼ中央に断面Ｊ字状の鉤状部材２１の上部が固着され、バッテリケース６の前面ほぼ中央部に係止部材２２が鉤状部材２１に係脱自在に係止すべく取り付けられている。
【００２０】
この係止部材２２はボンネットキャッチ等と称され、特に図２ないし図４に示されるように構成され、バッテリケース６の前面に固着された支持体２３と、支持点に相当する支持体２３の上端の支持部２４において回転自在に枢支された基体２５と、一端が支持部２４の少し下方の枢支部２６において回転自在に枢支されて基体２５の回転時に他端が鉤状部材２１に係止する係止体２７とから成る。
【００２１】
ここで、係止体２７は、平面視ほぼコ字状を成し、鉤状部材２１に係止した状態で側面から見て前方に湾曲した形状を有し（図４参照）、先端部が屈曲されて基体２５に回転自在に枢支されている（図３参照）。
【００２２】
そして、係止体２７の枢支部２６が基体２５の支持体２３への支持部２４よりも下方に位置しているため、係止体２７を鉤状部材２１に引っかけた状態で基体２５の下端側を下向きに回転させ、特に図４に示されるように、係止体２７の枢支部２６が支持部２４よりも後方に位置するまで基体２５の下端側を回転させることにより、係止体２７のバネ性による復元力が作用する係止体２７の枢支部２６がデッドポイントである支持部２４を越えることになり、係止体２７が基体２５により下方に引っ張られて鉤状部材２１に係止した状態に維持されるのである。
【００２３】
更に、基体２５の下端部には保持部材２９の上端部が固着され、この保持部材２９は平板の中央やや下寄りの部分が後側に凹状に屈曲加工されて屈曲部３０が形成されており（図２、図４参照）、この屈曲部３０にボルト挿通孔３１が透設され、このボルト挿通孔３１に固定具である六角穴付ボルト３２が挿通されるようになっている。このとき、凹状の屈曲部３０の上下面によって図１０に示すような錠締め構造が実現されている。
【００２４】
そして、バッテリケース６の前面に固着された取付体３３に形成された雌ねじ３４に六角穴付ボルト３２が螺合され、これにより係止体２７が鉤状部材２１に係止した状態に保持されると共に、保持部材２９の下端部がバッテリケース６の前面に固定される。尚、３６はワッシャである。
【００２５】
また、図１に示すように、バッテリケース６の前面の左上端部に透設された一対の挿通孔を介して両引出ケーブル５ａ、５ｂがバッテリケース６の外に引き出され、コネクタ４１により図示しない外部負荷に接続され、このコネクタ４１がバッテリケース６に取り付けられた断面コ字状のカバー４２により包被されている。
【００２６】
従って、上記した実施形態によれば、基体２５を回転して係止体２７を基体２５により下方に引っ張って係止体２７を鉤状部材２１に係止した状態に維持する構造であるため、各部材の加工誤差や取り付け時の寸法誤差が多少あっても、係止部材２２と鉤状部材２１との係止部分でこれらの誤差を吸収することが可能になり、従来のようなボルト挿通孔の位置合わせ作業が不要になり、バッテリカバー７の固定作業を効率よく行うことができ、しかも六角穴付ボルト３２により保持部材２９を簡単に固定することができ、防爆仕様のフォークリフトに好適である。
【００２７】
なお、この発明の他の実施形態として、図５に示すように、バッテリケース６前面の係止部材２２の左側に、蝶番５１により、凹字状に形成された保持部材５２の左端部を回転自在に取り付け、保持部材５２の右端部にコ字状の屈曲部５３を形成すると共に、この屈曲部５３にボルト挿通孔５４を形成し、屈曲部５３の左右の側面により図１０に示すような錠締め構造を実現し、保持部材５２の中央部分にて基体２５の下端部を押えつつ、ボルト挿通孔５４にワッシャ３６を介して六角穴付ボルト３２を挿通し、バッテリケース６の前面の係止部材２２の右側に固着した取付体５４の雌ねじ５５にボルト３２を螺合するようにしてもよく、この場合も上記した実施形態と同等の効果が得られる。
【００２８】
また、上記した各実施形態では、鉤状部材２１をバッテリカバー７側に、係止部材２２をバッテリケース６側にそれぞれ設けた場合について説明しているが、鉤状部材２１をバッテリケース６側に、係止部材２２をバッテリカバー７側にそれぞれ設けても構わない。
【００２９】
更に、上記した各実施形態では、係止部材２２を、支持体２３、基体２５及び係止体２７により構成した場合について説明したが、係止部材はこのような構成に限定されるものではなく、要するに鉤状部材２１に係止できて保持部材により係止状態に保持される構成であればよい。
【００３０】
また、保持部材を固定する固定具は、上記した六角穴付ボルト３２に限らず、通常の六角ボルトであってもよく、錠締め構造としても図１０に示すような壁状凸部以外に、図９に示すような環状凸部から成るものであっても構わない。
【００３１】
更に、上記した各実施形態では、防爆仕様のカウンタバランス型フォークリフトの駆動用バッテリに適用した場合について説明したが、その他の防爆仕様の電気車駆動用バッテリであっても本発明を適用することができ、上記した実施形態と同等の効果を得ることができるのは勿論である。
【００３２】
また、本発明は上記した各実施形態に限定されるものではなく、その趣旨を逸脱しない限りにおいて上述したもの以外に種々の変更を行うことが可能である。
【００３３】
【発明の効果】
以上のように、請求項１又は２に記載の発明によれば、係止部材を鉤状部材に係止して保持部材によりその係止状態を保持すると共に、固定具により保持部材を固定す構造であるため、各部材の加工誤差や取り付け時の寸法誤差が多少あっても、係止部材と鉤状部材との係止部分でこれらの誤差を吸収することが可能になり、バッテリカバーの固定作業の簡素化を図ることができ、バッテリ部分の組立作業の高効率化を図ることが可能になり、防爆仕様の電気車駆動用バッテリに対して好適である。
【００３４】
また、請求項１又は２に記載の発明によれば、係止部材の係止体を鉤状部材に係止し、基体を回転することで係止体を引っ張るようにして係止体を鉤状部材に係止した状態に維持することができ、非常に簡単な操作によってバッテリカバーを固定することが可能になる。
【００３５】
また、請求項１又は２に記載の発明によれば、バッテリが、例えば防爆仕様の電気車の駆動用に用いられる場合であっても、バッテリカバーの固定作業を非常に効率的に行うことができる。
【００３６】
また、請求項１又は２に記載の発明によれば、保持部材の他端部を固定具により固定するだけで、係止部材を鉤状部材への係止状態を容易に保持することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a battery cover fixing structure for fixing a drive battery cover in an electric vehicle such as a forklift.
[0002]
[Prior art]
In a counterbalance forklift that is an electric vehicle, as shown in FIG. 6, a driving battery is accommodated in the lower portion of the operator seat 1. At this time, as shown in FIG. 7, a plurality of battery cells 2 are arranged vertically and horizontally, and each cell 2 is connected in series by a conductive connector 3 to form a battery 4, and a pair of lead-out cables 5a, 5b. Is connected to an external load.
[0003]
Such a battery is conventionally housed in a case-like battery case 6 as shown in FIG. 8, and the upper surface of the battery case 6 opened by a battery cover 7 that is rotatably provided by a hinge or the like. The battery cover 7 is closed in a closed state so as to be freely opened and closed, and the seat cover 1 is detachably mounted on the battery cover 7.
[0004]
By the way, when the counterbalance forklift described above is explosion-proof, the battery cover 7 is kept closed as defined in the industrial electrical facility technical guidelines by the Ministry of Labor Industrial Safety Research Institute. The fixing screws for fixing the fixing member are a locking structure, that is, a structure that can be operated only by a special tool other than a general tool such as a screwdriver, for example, around an insertion hole such as a hexagon bolt or a hexagon socket head bolt. In addition, the fixing member 9 having a structure as shown in FIG. 8 has been conventionally used. The fixing member 9 has a structure having wall-like convex portions on both sides of the annular convex portion or the insertion hole.
[0005]
That is, as shown in FIG. 8, a support plate 11 is fixed to a frame 10 of a forklift on which a battery case 6 is placed with a bolt or the like, and a lower end portion of a fastening plate 13 is rotatable on a support plate 11 by a hinge 12. At this time, the support plate 11 and the fastening plate 13 are disposed so that the fastening plate 13 extends along the front surface of the battery case 6.
[0006]
Further, the upper portion of the connecting plate 14 is fixed to the front center of the battery cover 7, and two female screws are formed on the connecting plate 14. When the battery cover 7 is closed, the upper end of the fastening plate 13 is the lower portion of the connecting plate 14. The lengths and positions of the fastening plate 13 and the connecting plate 14 are set so as to overlap with the front side, and two bolt insertion holes 15 are formed at the upper end portion of the fastening plate 13 and the positions overlapping the female screws of the connecting plate 14. The bolts 16 are respectively inserted into the bolt insertion holes 15 and screwed into the female screws of the connecting plate 14, and the fastening plate 13 is fastened to the connecting plate 14 to fix the battery cover 7. At this time, as shown in FIG. 9, the annular protrusions 17 are integrally formed around the bolt insertion holes 15, or the wall-like protrusions 18 are formed on both sides of the bolt insertion holes 15 by welding as shown in FIG. Thus, a locking structure is realized.
[0007]
[Problems to be solved by the invention]
However, in the case of the above-described conventional battery cover fixing structure, it is very difficult to align both the bolt insertion holes 15 of the fastening plate 13 and the female screws of the connecting plate 14 due to processing errors and dimensional errors at the time of attachment. Therefore, the bolt 16 cannot be easily screwed into the female screw, and the efficiency of fixing the battery cover 7 is reduced.
[0008]
The problem to be solved by the present invention is to simplify the battery cover fixing operation.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a battery cover fixing structure for fixing a battery cover that opens and closes an upper surface of a battery case containing a battery composed of a plurality of cells arranged vertically and horizontally. A hook-shaped member fixed to one front surface of the battery cover or the battery case; and a locking member attached to the other front surface of the battery cover or the battery case and detachably locked to the hook-shaped member; A holding member that is provided on the other front surface of the battery cover or the battery case and holds the locking member in a state where the locking member is locked to the hook-shaped member, and the holding member is connected to the battery cover or the And a fixture that is fixed to the other front surface of the battery case.
[0010]
If comprised in this way, a latching member will be latched by a hook-shaped member, while the latching state will be hold | maintained with a holding member, and a holding member will be fixed with a fixing tool.
[0011]
Therefore, even if there is some processing error or dimensional error at the time of attachment, these errors can be absorbed by the locking portion between the locking member and the hook-shaped member. Therefore, it is possible to lock the locking member to the hook-shaped member without simplifying the positioning of the battery cover, thereby simplifying the fixing operation of the battery cover.
[0012]
Further, according to the present invention, the locking member includes a base body rotatably supported at a support point on one end side on the other front surface of the battery cover or the battery case, and one end rotatably attached to the base body. When the other end side of the base body is rotated with the other end being engaged with the hook-shaped member and the other end is rotated with the hook-shaped member. The locking body is maintained in a state of being pulled by the base and locked to the hook-shaped member.
[0013]
In this way, the locking body of the locking member is locked to the hook-shaped member, and the locking body is locked to the hook-shaped member by pulling the locking body by rotating the base. The battery cover can be fixed by a very simple operation.
[0014]
Further, the present invention is characterized in that one end of the holding member is fixed to the other end portion of the base, and the other end portion is fixed by the fixing tool.
[0015]
Further, the present invention is characterized in that one end portion of the holding member is rotatably attached to the other front surface of the battery cover or the battery case, and the other end portion is fixed by the fixture.
[0016]
If it does in this way, a locking member can be easily held in a locked state to a hook-shaped member only by fixing the other end of a holding member with a fixture.
[0017]
In addition, the present invention is characterized in that the fixture has an explosion-proof locking structure. In this way, even when the battery is used for driving an explosion-proof electric vehicle, for example, the battery cover can be fixed very efficiently.
