Description

本発明は、メンテナンスプラグを保護するプラグカバーに関する。   The present invention relates to a plug cover for protecting a maintenance plug.

従来の車両、特に電気自動車においては、大容量のバッテリを搭載しているため整備時等に作業者が感電しないように電流を遮断するメンテナンスプラグが設けられている。このメンテナンスプラグは、通常はバッテリケースのカバー上面に設けられており、ゴムや金属の蓋によって覆われている。   Conventional vehicles, particularly electric vehicles, are equipped with a large-capacity battery, and are therefore provided with a maintenance plug that cuts off the current so that an operator does not get an electric shock during maintenance. This maintenance plug is usually provided on the upper surface of the cover of the battery case, and is covered with a rubber or metal lid.

メンテナンスプラグを覆うプラグカバーは、バッテリが加熱して内部の空気が膨張するため、これを逃がす呼吸口を必要とする。また、プラグカバーとしては、水や塵埃、さらには虫等の異物が混入することを防止すべく、開閉時の密着性を得るために比較的高価な樹脂材料が用いられている。これ等のことから、従来ではコストアップすることが避けられなかった。
本発明は上述の問題点を解決し、異物の混入を確実に防止することができると共にコストダウンを図ることが可能なプラグカバーの提供を目的とする。 The plug cover that covers the maintenance plug needs a breathing port for releasing the air because the battery is heated and the internal air expands. In addition, as the plug cover, a relatively expensive resin material is used to obtain adhesion at the time of opening and closing in order to prevent foreign matters such as water, dust, and insects from entering. For these reasons, it has been unavoidable to increase the cost.
SUMMARY OF THE INVENTION An object of the present invention is to provide a plug cover that solves the above-described problems and can reliably prevent foreign matters from being mixed and can reduce costs.

In the same figure, the code | symbol 1 has shown the battery case arrange | positioned at the vehicle interior bottom part of an electric vehicle, and the some battery is accommodated in the inside. A plug cover 2, which is a characteristic part of the present invention, is provided in the upper part of the battery case 1, and a maintenance plug 3 that is removed at the time of work or the like is housed in the plug cover 2 as shown in FIG. .

プラグカバー２は、図２に示すように、メンテナンスプラグ３の周囲を壁状に包囲するカバー枠２ａと、ヒンジ部２ｃによってカバー枠２ａに対して揺動自在に支持された蓋体２ｂと、カバー枠２ａに固定されたファスナ部２ｄと、蓋体２ｂに固定されファスナ部２ｄに対して係合可能なファスナ部２ｅと、カバー枠２ａが固定されバッテリケース１に固定される固定部２ｆとを有している。   As shown in FIG. 2, the plug cover 2 includes a cover frame 2a that surrounds the periphery of the maintenance plug 3 like a wall, a lid 2b that is swingably supported by the cover frame 2a by a hinge portion 2c, Fastener portion 2d fixed to cover frame 2a, fastener portion 2e fixed to lid 2b and engageable with fastener portion 2d, fixing portion 2f fixed to battery case 1 with cover frame 2a fixed have.

カバー枠２ａ、蓋体２ｂ、固定部２ｆはそれぞれ樹脂によって形成されており、カバー枠２ａとファスナ部２ｄ及び蓋体２ｂとファスナ部２ｅとはそれぞれ超音波溶着によって固定されている。またヒンジ部２ｃは金属製であり、カバー枠２ａ及び蓋体２ｂに対してそれぞれ接着またはねじ止め等の周知の方法によって固定されている。   The cover frame 2a, the lid body 2b, and the fixing portion 2f are each formed of resin, and the cover frame 2a and the fastener portion 2d and the lid body 2b and the fastener portion 2e are fixed by ultrasonic welding. The hinge portion 2c is made of metal, and is fixed to the cover frame 2a and the lid body 2b by a known method such as adhesion or screwing.

各ファスナ部２ｄ，２ｅには、両者を係合及び離脱させる、即ちカバー枠２ａと蓋体２ｂとの接合を開閉自在な開閉部２ｇがそれぞれ嵌合されており、開閉部２ｇには各ファスナ部２ｄ，２ｅを開閉する際に把持される摘み部２ｈが取り付けられている。摘み部２ｈには固定用ボルト（固定部材、締結部材）が貫通可能な孔部（第１の孔部）が設けられており、ヒンジ部２ｃには固定用ボルトが挿通可能な固定用ナット２ｉ（第２の孔部）が固定されている。   Each fastener portion 2d, 2e is fitted with an opening / closing portion 2g that can be engaged and disengaged, that is, the cover frame 2a and the lid 2b can be opened and closed. A knob portion 2h that is gripped when the portions 2d and 2e are opened and closed is attached. The knob 2h is provided with a hole (first hole) through which a fixing bolt (fixing member, fastening member) can pass, and the fixing nut 2i through which the fixing bolt can be inserted into the hinge 2c. The (second hole) is fixed.

上述の構成より、図３に示すメンテナンスプラグ３が開放された状態からカバー枠２ａに対して蓋体２ｂを閉じた状態とし、摘み部２ｈを把持して通常のファスナと同様に開閉部２ｇを移動させて各ファスナ部２ｄ，２ｅを係合させる。そして、その状態から図４（ａ）に示すように摘み部２ｈをヒンジ部２ｃに重合させ、摘み部２ｈの孔部を介して固定用ボルト４を固定用ナット２ｉに螺合させることにより、メンテナンスプラグ３が閉じられた状態となる。   With the above-described configuration, the lid 2b is closed with respect to the cover frame 2a from the state in which the maintenance plug 3 shown in FIG. The fasteners 2d and 2e are engaged by moving. Then, from that state, as shown in FIG. 4A, the knob portion 2h is superposed on the hinge portion 2c, and the fixing bolt 4 is screwed into the fixing nut 2i through the hole portion of the knob portion 2h. The maintenance plug 3 is closed.

上述の構成において、本発明のプラグカバー２はファスナ部２ｄ，２ｅを互いに係合させることによってメンテナンスプラグ３が閉じられた状態となり、各ファスナ部２ｄ，２ｅ間には図４（ｂ）に示すように隙間があることから、バッテリが加熱してプラグカバー２内部の空気が膨張しても符号５で示すようにこれを前記隙間から逃がすことができ、呼吸口を省略できることからコストダウンを図ることができる。   In the configuration described above, the plug cover 2 of the present invention is in a state in which the maintenance plug 3 is closed by engaging the fastener portions 2d and 2e with each other, and the gap between the fastener portions 2d and 2e is shown in FIG. Thus, even if the battery is heated and the air inside the plug cover 2 expands, it can be escaped from the gap as indicated by reference numeral 5 and the breathing port can be omitted, thereby reducing costs. be able to.

また、ファスナ部２ｄ，２ｅによってカバー枠２ａと蓋体２ｂとが確実に結合されるので、カバー枠２ａ及び蓋体２ｂとしてポリエチレンやポリプロピレン等の安価な樹脂を用いても水、塵埃、虫等の異物が混入することを確実に防止することができ、コストダウンを図ることができる。   Further, since the cover frame 2a and the lid 2b are securely coupled by the fastener portions 2d and 2e, even if an inexpensive resin such as polyethylene or polypropylene is used for the cover frame 2a and the lid 2b, water, dust, insects, etc. It is possible to reliably prevent the foreign matter from being mixed in, and to reduce the cost.

さらに、摘み部２ｈ及び開閉部２ｇは各ファスナ部２ｄ，２ｅによってカバー枠２ａと蓋体２ｂとを結合した後に固定部材である固定用ボルト４によって固定用ナット２ｉに固定されるので、メンテナンスプラグ３を開放する際には特殊な工具が必要となり、安全性を高めることができる。固定用ナット２ｉに代えて、ヒンジ部２ｃに直接タップを形成してもよい。また締結部材として固定用ボルト４を挙げたが、締結部材としては六角ボルトや六角穴付きボルト等のボルトの他、ねじ類やビス等を用いてもよい。   Further, since the knob portion 2h and the opening / closing portion 2g are fixed to the fixing nut 2i by the fixing bolt 4 which is a fixing member after the cover frame 2a and the lid body 2b are joined by the fastener portions 2d and 2e, the maintenance plug When opening 3, a special tool is required, and safety can be improved. Instead of the fixing nut 2i, a tap may be formed directly on the hinge portion 2c. Moreover, although the fixing bolt 4 was mentioned as a fastening member, screws, screws, or the like may be used as the fastening member in addition to a bolt such as a hexagon bolt or a hexagon socket head bolt.

上記実施形態の変形例として、固定用ボルト４に代えて、図４（ａ）に示すように、その頭部がヒンジ部２ｃの幅よりも大きくなるように形成された固定用ボルト６を固定部材として用いてもよい。この構成により、上述の実施形態に比してヒンジ部２ｃに対する摘み部２ｈの固定力を増加することができ、固定用ボルト６が簡単には外れないことから安全性をより一層高めることができる。   As a modification of the above embodiment, instead of the fixing bolt 4, as shown in FIG. 4A, a fixing bolt 6 formed so that its head is larger than the width of the hinge portion 2c is fixed. It may be used as a member. With this configuration, it is possible to increase the fixing force of the knob portion 2h with respect to the hinge portion 2c as compared with the above-described embodiment, and it is possible to further enhance safety because the fixing bolt 6 is not easily detached. .
