Description

本発明は、自動車専用道路のサービスエリアや商業施設の駐車場、あるいは集合住宅の駐車場などに設置される充電スタンドに使用されるコンセントユニットに関するものである。   The present invention relates to an outlet unit used for a charging station installed in a service area of an automobile exclusive road, a parking lot of a commercial facility, or a parking lot of an apartment house.

近年、二酸化炭素の排出量や石油(ガソリンや軽油など)の消費量を削減することができて地球環境に優しい自動車として、内燃機関(ガソリンエンジンやディーゼルエンジンなど)と電動機(モータ)を併用して走行するハイブリッド自動車や電動機のみで走行する電気自動車が注目を集めている。また、ハイブリッド自動車の形態として、現在は走行中に二次電池を充電するものが主流であるが、家庭用の交流電源(商用交流電源)を用いて駐車中に二次電池を充電し、初めに電動機で走行するとともに二次電池の残容量が低下したら内燃機関で走行するものも近く市販される予定である。尚、後者の形態の自動車はプラグインハイブリッド自動車と呼ばれている。   In recent years, internal combustion engines (gasoline engines, diesel engines, etc.) and electric motors (motors) have been used in combination as environmentally friendly vehicles that can reduce carbon dioxide emissions and oil (gasoline, light oil, etc.) consumption. Hybrid cars that run on the road and electric cars that run only on electric motors are attracting attention. In addition, as a form of hybrid vehicle, currently, the one that recharges the secondary battery while driving is the mainstream, but the secondary battery is charged while parking using a home AC power source (commercial AC power source). If the remaining capacity of the secondary battery decreases when the vehicle runs with an electric motor, a vehicle that runs with an internal combustion engine will soon be marketed. The latter type of vehicle is called a plug-in hybrid vehicle.

ところで、電気自動車やプラグインハイブリッド自動車(以下では、これら２種類の自動車を合わせて「電気自動車」と呼ぶ。)が普及するためには、二次電池を充電するためのインフラを整備する必要がある。具体的には、自動車専用道路のサービスエリアや商業施設の駐車場、あるいは集合住宅の駐車場などの公共の場(パブリック・スペース)に不特定多数の人が利用可能な電源(コンセント)を多数設置しなければならない。ここで、屋外にコンセントを設置するものとして、下部が地中に埋設されたポール内にコンセントを配設し、住戸内(屋内)の住宅用分電盤から分岐された給電線を前記コンセントに接続してなるコンセント装置(電源ポールとも呼ばれる。)が従来より提供されている(例えば、特許文献１参照)。特許文献１に記載されている電源ポールは、円筒状のポールの上部に扉付きのケーシングが取り付けられ、２つのコンセントがケーシング内に収納されて構成されており、ケーシングの扉を開いた状態でケーシング内のコンセントに電源プラグが差込接続されるものである。   By the way, in order for electric vehicles and plug-in hybrid vehicles (hereinafter, these two types of vehicles are collectively referred to as “electric vehicles”) to spread, it is necessary to develop an infrastructure for charging secondary batteries. is there. Specifically, there are many power sources (outlets) that can be used by an unspecified number of people in public spaces (public spaces) such as service areas on automobile roads, parking lots for commercial facilities, and parking lots for apartment buildings. Must be installed. Here, as an outlet to be installed outdoors, the outlet is arranged in a pole with the lower part buried in the ground, and the feeder line branched from the residential distribution board in the dwelling unit (indoor) is used as the outlet. A connected outlet device (also called a power pole) has been conventionally provided (see, for example, Patent Document 1). The power pole described in Patent Document 1 is configured such that a casing with a door is attached to the top of a cylindrical pole and two outlets are housed in the casing, and the casing door is opened. A power plug is plugged into an outlet in the casing.

ところで、特許文献１に記載されている電源ポールを充電スタンドに利用した場合、２台の電気自動車までなら１台の充電スタンド(電源ポール)で同時に充電することができるが、３台以上の電気自動車を同時に充電するためには複数台の充電スタンド(電源ポール)を設置するか、あるいはケーシング内に３個以上のコンセントを収納した別タイプの充電スタンド(電源ポール)を設置する必要がある。したがって、電気自動車の普及率増加に伴ってコンセントの個数を増やそうとしたとき、新たに充電スタンド(電源ポール)を設置しなければならない。   By the way, when the power pole described in Patent Document 1 is used as a charging stand, up to two electric vehicles can be charged simultaneously with one charging stand (power pole). In order to charge an automobile at the same time, it is necessary to install a plurality of charging stands (power poles), or to install another type of charging stand (power pole) containing three or more outlets in the casing. Therefore, when the number of outlets is increased with the increase in the penetration rate of electric vehicles, a charging stand (power pole) must be newly installed.

The outlet block 12 includes a push latch (not shown) for maintaining the closed position against the spring force of the torsion coil spring, and the speed at which the outlet block 12 rotates from the closed position to the open position is reduced. A speed reduction mechanism (not shown) is attached.

扉１３は扁平な矩形箱状に形成されており、図３(ｂ)に示すように上下一対のヒンジ部１４，１４によって右側端部が筐体１１の前面下部に軸支されている。また、扉１３の背面側には、硬貨を投入することで施錠可能となり且つ解錠すると施錠時に投入した硬貨が返却されるロック装置１５が取着されており、扉１３の前面にロック装置１５の鍵孔部１５ａが露出している。さらに、扉１３の背面側下部と筐体１１の内側面下部とがアーム機構１６によって連結されており、このアーム機構１６により扉１３の回動範囲が規制されるとともに扉１３が開位置(図３(ｂ)に示す位置。以下同じ。)で保持される。尚、扉１３が閉位置(図３(ａ)に示す位置。以下同じ。)にあるとき、扉１３の下端と筐体１１の下端との間に充電ケーブル１００を通すための隙間が空くようになっている。   The door 13 is formed in a flat rectangular box shape, and the right end is pivotally supported on the lower front portion of the housing 11 by a pair of upper and lower hinges 14 and 14 as shown in FIG. Further, on the back side of the door 13, a lock device 15 that can be locked by inserting coins and returns coins that are inserted when unlocked is attached. The keyhole portion 15a is exposed. Furthermore, the lower part of the back side of the door 13 and the lower part of the inner side surface of the housing 11 are connected by an arm mechanism 16, and the arm mechanism 16 regulates the rotation range of the door 13 and the door 13 is opened (see FIG. 3 (b) (the same applies hereinafter)). When the door 13 is in the closed position (the position shown in FIG. 3A, the same applies hereinafter), a gap for passing the charging cable 100 is provided between the lower end of the door 13 and the lower end of the housing 11. It has become.

また、コンセントユニット１０にはインターロック装置(図示せず)が設けられており、このインターロック装置によって、コンセントブロック１２が開位置にあるときはコンセント２０への通電がオフされ、コンセントブロック１２が閉位置にあるときにだけコンセント２０への通電がオンされるようになっている。   Further, the outlet unit 10 is provided with an interlock device (not shown). When the outlet block 12 is in the open position, the power supply to the outlet 20 is turned off by the interlock device, and the outlet block 12 is Only when it is in the closed position, the power supply to the outlet 20 is turned on.

上述のように構成されるコンセントユニット１０は、前面側からスタンド本体１内の収納空所８内に収納され、一対の取付板６，６に対して筐体１１がねじ止めされることでスタンド本体１に対して固定される。上述したようにスタンド本体１内には同一寸法の４つの収納空所８が上下方向に並設されており、これら４つの収納空所８の何れにもコンセントユニット１０を収納することができる。ここで、取付板６，６に取り付けられたコンセントユニット１０の筐体１１とスタンド本体１の背板４との間には外部から引き込まれる複数の電源ケーブル(図示せず)を左右方向に並べて配線するための配線スペースが設けられている(図４参照)。また、筐体１１の背面上部と背板４との間にそれぞれブレーカＢＲが設置され、配線スペースに配線された電源ケーブルがブレーカＢＲの１次側に接続されるとともに、ブレーカＢＲの２次側が図示しない電線によりインターロック装置を介してコンセント２０と接続されている。   The outlet unit 10 configured as described above is housed in the housing space 8 in the stand main body 1 from the front side, and the housing 11 is screwed to the pair of mounting plates 6 and 6. Fixed to the main body 1. As described above, the four storage cavities 8 having the same dimensions are arranged in the vertical direction in the stand main body 1, and the outlet unit 10 can be stored in any of these four storage cavities 8. Here, a plurality of power cables (not shown) drawn from outside are arranged in the left-right direction between the housing 11 of the outlet unit 10 attached to the attachment plates 6 and 6 and the back plate 4 of the stand body 1. A wiring space for wiring is provided (see FIG. 4). In addition, a breaker BR is installed between the rear upper portion of the housing 11 and the back plate 4, and a power cable wired in the wiring space is connected to the primary side of the breaker BR, and the secondary side of the breaker BR is It is connected to the outlet 20 by an electric wire (not shown) through an interlock device.

次に、本実施形態の充電スタンドの使用手順について説明する。まず、扉１３を開いてからコンセントパネル２２の前面を押すと、プッシュラッチのラッチが外れてコンセントブロック１２が閉位置から開位置まで回動する(図５参照)。尚、コンセントパネル２２の下端部には、前後方向において扉１３の上端部と重なる規制片２２ａが下向きに突設されており、扉１３が閉まっている状態でプッシュラッチのラッチが外れても規制片２２ａが扉１３に当接することでコンセントブロック１２が回動しないようになっている。そして、充電ケーブル１００の電源プラグの接触子を差込口２０ａに差し込むことでコンセント２０に充電ケーブル１００を接続する。このとき、コンセント２０の差込口２０ａがスタンド本体１の前面よりも前方へ突出しているので、電源プラグを差込口２０ａに差し込む作業が容易に行えるものである。しかも、スタンド本体１前面より前方へ突出したコンセント２０の差込口２０ａが水平面よりも下を向いているため、雨天時に差込口２０ａに雨水が掛かるのを防ぐことができるものである。   Next, the procedure for using the charging stand of this embodiment will be described. First, when the front of the outlet panel 22 is pushed after opening the door 13, the latch of the push latch is released and the outlet block 12 rotates from the closed position to the open position (see FIG. 5). A regulating piece 22a that overlaps with the upper end portion of the door 13 in the front-rear direction protrudes downward from the lower end portion of the outlet panel 22 so that the push latch latch is released even when the door 13 is closed. The outlet block 12 is prevented from rotating by the piece 22a coming into contact with the door 13. Then, the charging cable 100 is connected to the outlet 20 by inserting the contact of the power plug of the charging cable 100 into the insertion port 20a. At this time, since the insertion port 20a of the outlet 20 protrudes forward from the front surface of the stand main body 1, the work of inserting the power plug into the insertion port 20a can be easily performed. Moreover, since the outlet 20a of the outlet 20 that protrudes forward from the front surface of the stand body 1 faces downward from the horizontal plane, it is possible to prevent rainwater from splashing on the outlet 20a when it rains.

電源プラグをコンセント２０に接続した後、コンセントパネル２２の前面を押してコンセントブロック１２を開位置から閉位置まで回動させるとともにプッシュラッチをラッチさせてコンセントブロック１２を閉位置に固定する。続いて、ロック装置１５に硬貨を投入してから扉１３を閉め、図示しない鍵を用いてロック装置１５を施錠する。このとき、充電ケーブル１００は閉めた扉１３の下端と、下側の収納空所８に収納されている別のコンセントユニット１０のコンセントパネル２２の上端との間に形成されている隙間を通してスタンド本体１の外に引き出される。   After connecting the power plug to the outlet 20, the front of the outlet panel 22 is pushed to rotate the outlet block 12 from the open position to the closed position, and the push latch is latched to fix the outlet block 12 in the closed position. Subsequently, after inserting coins into the lock device 15, the door 13 is closed, and the lock device 15 is locked using a key (not shown). At this time, the charging cable 100 passes through a gap formed between the lower end of the closed door 13 and the upper end of the outlet panel 22 of another outlet unit 10 stored in the lower storage space 8. Pulled out of one.

一方、電気自動車の充電が終了すれば、ロック装置１５を解錠して扉１３を開き、コンセントブロック１２を閉位置から開位置に回動した後、電源プラグをコンセント２０の差込口２０ａから引き抜く。ここで、コンセントブロック１２が開位置にあるときはインターロック装置によってコンセント２０への通電がオフされているため、電源プラグをコンセント２０の差込口２０ａに抜き差しする際の感電事故を防ぐことができる。   On the other hand, when the charging of the electric vehicle is completed, the lock device 15 is unlocked, the door 13 is opened, the outlet block 12 is rotated from the closed position to the open position, and then the power plug is inserted from the outlet 20a of the outlet 20. Pull out. Here, when the outlet block 12 is in the open position, since the power supply to the outlet 20 is turned off by the interlock device, it is possible to prevent an electric shock accident when the power plug is inserted into and removed from the outlet 20a of the outlet 20. it can.

電源プラグをコンセント２０から引き抜いた後、コンセントパネル２２の前面を押してコンセントブロック１２を開位置から閉位置まで回動させるとともにプッシュラッチをラッチさせてコンセントブロック１２を閉位置に固定する。続いて、ロック装置１５から返却された硬貨を回収してから扉１３を閉める(図６参照)。   After the power plug is pulled out from the outlet 20, the front surface of the outlet panel 22 is pushed to rotate the outlet block 12 from the open position to the closed position, and the push latch is latched to fix the outlet block 12 in the closed position. Subsequently, after the coins returned from the lock device 15 are collected, the door 13 is closed (see FIG. 6).

図７(ａ)は本実施形態の充電スタンドを駐車場に設置した状態を模式的に示した平面図であり、図７(ｂ)は特許文献１に記載されている電源ポール２００，２００を同じ駐車場に設置したときの平面図である。図７(ｂ)に示すように、従来の電源ポール２００はケーシング内に２つのコンセントしか有していないため、電気自動車ＥＶを駐車する２台分のスペース毎に１台ずつ設置されなければならず、しかも、２台の電気自動車ＥＶを同時に充電するためにはケーシングの扉を開いたままにしておかなければならない。そのため、電気自動車ＥＶの所有者が充電中に駐車場から離れた場合、充電ケーブル１００が持ち去られてしまったり、子供が悪戯でコンセント２０から充電ケーブル１００の電源プラグを引き抜いてしまうといった不具合の生じる虞がある。   FIG. 7A is a plan view schematically showing a state where the charging stand of the present embodiment is installed in a parking lot, and FIG. 7B shows power poles 200 and 200 described in Patent Document 1. It is a top view when installing in the same parking lot. As shown in FIG. 7B, since the conventional power pole 200 has only two outlets in the casing, one unit must be installed for every two spaces for parking the electric vehicle EV. Moreover, in order to charge the two electric vehicles EV at the same time, the casing door must be left open. Therefore, when the owner of the electric vehicle EV leaves the parking lot during charging, the charging cable 100 is taken away, or the child pulls out the power plug of the charging cable 100 from the outlet 20 by mischief. There is a fear.

これに対して本実施形態の充電スタンドでは、スタンド本体１内の４つの収納空所８にそれぞれコンセントユニット１０を収納することで４つのコンセント２０を設けることが可能であるから、図７(ａ)に示すように電気自動車ＥＶを駐車する４台分のスペース毎に１台を設置すればよく、設置のためのコストが削減できるものである。さらに、コンセントユニット１０における筐体１１の前面下部が扉１３によって個別に閉塞できるので、充電ケーブル１００の盗難防止や悪戯防止などの安全性を確保しつつ複数台の電気自動車ＥＶを同時に充電することが可能となる。尚、必ずしも全ての収納空所８にコンセントユニット１０を収納しなければならないものではなく、例えば、２台分の駐車スペースしかない駐車場に設置される場合であれば４つの収納空所８のうちの２つの収納空所８のみにコンセントユニット１０を収納すればよい。   On the other hand, in the charging stand of the present embodiment, four outlets 20 can be provided by storing the outlet units 10 in the four storage spaces 8 in the stand body 1, respectively. As shown in (1), it is only necessary to install one vehicle for every four spaces where the electric vehicle EV is parked, and the cost for installation can be reduced. Furthermore, since the lower front portion of the housing 11 in the outlet unit 10 can be individually closed by the door 13, a plurality of electric vehicles EV can be charged at the same time while ensuring safety such as prevention of theft and mischief of the charging cable 100. Is possible. Note that the outlet units 10 do not necessarily have to be stored in all the storage cavities 8, and for example, when installed in a parking lot having only two parking spaces, The outlet unit 10 may be stored in only two of the storage spaces 8.

このように本実施形態の充電スタンドは、スタンド本体１の収納空所８内にコンセントユニット１０を着脱自在に収納する構成を採用したことにより、コンセント２０の個数の増加に対応可能であり且つ修理や交換などのメンテナンス作業の作業性も向上するという利点がある。また、本実施形態では全てのコンセント２０をコンセントユニット１０に設けているが、このうちの一つのコンセント２０(第１のコンセント)をモジュール化せずにスタンド本体１に組み付け、他の複数(本実施形態では３つ)のコンセント２０をコンセントユニット１０として着脱自在に収納空所８に収納する構成としても構わない。   As described above, the charging stand according to the present embodiment employs a configuration in which the outlet unit 10 is detachably stored in the storage space 8 of the stand body 1, so that the number of outlets 20 can be increased and repaired. There is an advantage that workability of maintenance work such as replacement and replacement is improved. Further, in the present embodiment, all the outlets 20 are provided in the outlet unit 10, but one outlet 20 (first outlet) among them is assembled in the stand body 1 without being modularized, and other outlets (books). In the embodiment, three outlets 20 may be detachably stored in the storage space 8 as the outlet unit 10.
