Description

この発明は、車両用扉の開閉構造に関し、更に詳細には、有蓋トラック(バン)や保冷車等の箱型荷物室の開口部に設けられる車両用扉の開閉構造に関するものである。   The present invention relates to an opening / closing structure for a vehicle door, and more particularly to an opening / closing structure for a vehicle door provided at an opening of a box-type luggage compartment such as a covered truck (van) or a cold car.

バンタイプのトラックや保冷車等の有蓋車両は、後方に開口部を有する箱型荷物室を備え、その開口部に扉が開閉自在に取付けられている。この車両用扉は、ヒンジ接続した左右の扉が両側に開く観音式のものが一般的であるが、一方の扉をヒンジ開閉式とし、他方の扉をスライド式としたものも存在する。例えば、特許文献１に示す車両用扉１０は、図７および図８に示すように、箱型荷物室１２の開口部１２ａにヒンジ１４を介して取付けた開閉ドア１６と、この開閉ドア１６の内部１６ａへスライド自在に収納したスライドドア１８とから構成されている。   A covered vehicle such as a van type truck or a cold truck has a box-type luggage compartment having an opening at the back, and a door is attached to the opening so as to be opened and closed. This door for a vehicle is generally a kannon type in which the hinged left and right doors open on both sides, but there is also a type in which one door is a hinged opening / closing type and the other door is a sliding type. For example, as shown in FIGS. 7 and 8, a vehicle door 10 shown in Patent Document 1 includes an opening / closing door 16 attached to an opening 12 a of a box-type luggage compartment 12 via a hinge 14, and the opening / closing door 16. The slide door 18 is slidably accommodated in the interior 16a.

開閉ドア１６の箱型荷物室１２側の面(裏面)には、前記スライドドア１８を駆動して該開閉ドア１６からスライド自在に出入りさせ、開口部１２ａの開閉を行なうスライド駆動機構２０が設けられている。このスライド駆動機構２０は、図８に示すように、開閉ドア１６の裏面に取付けた駆動モータ２２と、該駆動モータ２２の駆動軸に設けたスプロケット２４と、開閉ドア１６の裏面に回転自在に設けたスプロケット２４と、両スプロケット２４,２４に巻掛けられて水平に延在するチェーン２６とから構成されている。開閉ドア１６の裏面には、前記チェーン２６と対応する位置に長孔１６ｂが水平に開設され(図８)、前記スライドドア１８に固定した連結片２８が前記長孔１６ｂを介して該チェーン２６に連結されている。従って、駆動モータ２２がチェーン２６を回転させると、前記連結片２８は該チェーン２６と共に前記長孔１６ｂに沿って移動し、前記スライドドア１８を開閉ドア１６に対し出入り自在にスライドさせる。   A slide drive mechanism 20 that opens and closes the opening 12a by driving the slide door 18 to be slidably moved in and out of the open / close door 16 is provided on the surface (back surface) of the open / close door 16 on the box-type luggage compartment 12 side. It has been. As shown in FIG. 8, the slide drive mechanism 20 includes a drive motor 22 attached to the back surface of the open / close door 16, a sprocket 24 provided on the drive shaft of the drive motor 22, and a back surface of the open / close door 16. The sprocket 24 is provided and a chain 26 that is wound around the sprockets 24 and 24 and extends horizontally. A long hole 16b is horizontally opened on the back surface of the open / close door 16 at a position corresponding to the chain 26 (FIG. 8), and a connecting piece 28 fixed to the slide door 18 is connected to the chain 26 through the long hole 16b. It is connected to. Accordingly, when the drive motor 22 rotates the chain 26, the connecting piece 28 moves along with the chain 26 along the long hole 16 b, and slides the slide door 18 with respect to the opening / closing door 16.

また、スライドドア１８をスライドさせる開閉機構としては、特許文献２に示す別の構造も提案されている。すなわち、特許文献２の図３には、一端がスライドドア３に固定したレール４３に摺動自在に連結した開閉アーム４２と、該アーム４２を所要中心角でスイングさせる駆動モータ４１とからなるスライドドア３の開閉機構が開示されている。またこれ以外に、パンダグラフ機構やワイヤ駆動機構等の車両用ウィンドレギュレータを、スライドドアの駆動機構に転用することも知られている。
特開平１０−１４７１４９号公報 特開２００３−８２９１９号公報 Further, another structure shown in Patent Document 2 has been proposed as an opening / closing mechanism for sliding the slide door 18. That is, FIG. 3 of Patent Document 2 shows a slide comprising an open / close arm 42 slidably connected to a rail 43 fixed at one end to the slide door 3 and a drive motor 41 that swings the arm 42 at a required central angle.

前述した各種の扉開閉構造は、何れもスライドドア１８をスライドさせる力(推進力)が充分でなく、箱型荷物室１２の開口部１２ａを確実に閉成し得ない欠点があった。殊に、開口部側またはドア側にパッキンを設けて、閉成時に開口部１２ａとスライドドア１８との気密性を確保しているが、従来の扉開閉構造では、前記スライドドア１８をパッキンへ充分押し付けることができず、保冷車の冷気が外部へ逃出し冷却効率を低下させる難点がある。   Each of the various door opening / closing structures described above has a drawback that the sliding force of the sliding door 18 (propulsive force) is not sufficient, and the opening 12a of the box-type luggage compartment 12 cannot be reliably closed. In particular, a packing is provided on the opening side or door side to ensure the airtightness between the opening 12a and the slide door 18 at the time of closing. However, in the conventional door opening / closing structure, the slide door 18 is used as a packing. There is a problem that the air cannot be pressed sufficiently, and the cold air of the cold car escapes to the outside and lowers the cooling efficiency.

そこで従来は、扉開閉構造の推進力不足を補うために、スライドドア１８の内側にフックを取付けると共に、荷物室１２の側に前記フックと係合して該ドア１８を引き寄せるラッチ機構を取付け、パッキンを充分に押圧変形させて気密性を向上させる構造が採用されている。しかしこの構造では、前記の如く、スライドドア１８の内側にフックを設けると共に、荷物室１２の側にラッチ機構を設ける必要があり、部品点数が増加し取付作業も繁雑化してコスト高になる難点がある。また前記ラッチ機構によるロックおよびロック解除には、ソレノイドやモータ等の電気的な駆動源を使用する場合が多い。このときは、電気的な駆動源と制御部とをハーネスで配線する必要があり、この作業にも手間を要する欠点がある。更に、スライドドア１８の完全閉成・開放を確認するには、その状態を検出するセンサを所要個所に設ける必要があるが、この場合もセンサと制御部とをハーネスで別途配線する手間を要している。   Therefore, conventionally, in order to compensate for the lack of propulsive force of the door opening / closing structure, a hook is attached to the inside of the slide door 18 and a latch mechanism that engages the hook and pulls the door 18 on the luggage compartment 12 side is attached. A structure is adopted in which the packing is sufficiently pressed and deformed to improve airtightness. However, in this structure, as described above, it is necessary to provide a hook inside the slide door 18 and a latch mechanism on the luggage compartment 12 side, which increases the number of parts, complicates the installation work, and increases the cost. There is. In many cases, an electric drive source such as a solenoid or a motor is used for locking and unlocking by the latch mechanism. In this case, it is necessary to wire the electrical drive source and the control unit with a harness, and this work also has a drawback that requires labor. Furthermore, in order to confirm whether the sliding door 18 is completely closed or opened, it is necessary to provide a sensor for detecting the state of the sliding door 18 at a required location. In this case also, it is necessary to separately wire the sensor and the control unit with a harness. is doing.

本発明は、従来の車両用扉の開閉構造に内在する前記問題に鑑み、これらを好適に解決するべく提案されたものであって、スライドドアの推進力を向上させて、箱型荷物室の開口部を充分に密閉保持し得る開閉構造を提供することを目的とする。また本発明の別の目的は、スライドドアをロックする機構やドアの開閉検出用のセンサ等をユニット化することで、取付けや配線の手間を軽減させた構造を提供することにある。   The present invention has been proposed in order to suitably solve these problems inherent in the conventional opening / closing structure of a vehicle door, and the propulsive force of the sliding door is improved so that the box-type luggage compartment is improved. It is an object of the present invention to provide an open / close structure that can sufficiently hold an opening. Another object of the present invention is to provide a structure that reduces mounting and wiring labor by unitizing a mechanism for locking a slide door, a sensor for detecting opening / closing of a door, and the like.

開閉ドア３４は、図示しない枠体を内板(裏面)３４ａと外板３４ｂとで挟んだ中空サンドイッチ構造をなし、内板３４ａおよび外板３４ｂの間にスライドドア３６を出入自在に収納する収納部３４ｃが画成されている。開閉ドア３４は、開口部３２ａの一方の縁部にヒンジ７２を介して接続され、図４(ｃ)に示す如く、箱型荷物室３２の外側へ開放可能になっている。なお、図２(ａ)は、スライド駆動機構３８を取付ける前の状態を示し、開閉ドア３４の内板３４ａには、該スライド駆動機構３８に設けたナット部材４０(後述)の往復動を許容する長孔３４ｄが幅方向に開設されている。 [Basic door structure]
The open / close door 34 has a hollow sandwich structure in which a frame (not shown) is sandwiched between an inner plate (rear surface) 34a and an outer plate 34b, and the slide door 36 is detachably stored between the inner plate 34a and the outer plate 34b. A portion 34c is defined. The opening / closing door 34 is connected to one edge of the opening 32a via a hinge 72, and can be opened to the outside of the box-type luggage compartment 32 as shown in FIG. 2A shows a state before the slide drive mechanism 38 is attached, and the inner plate 34a of the open / close door 34 is allowed to reciprocate a nut member 40 (described later) provided on the slide drive mechanism 38. FIG. A long hole 34d is formed in the width direction.

前記開閉ドア３４の収納部３４ｃに収納されたスライドドア３６は、該収納部３４ｃの上方に水平に設けたレールにローラ(何れも図示せず)を介して懸吊され、出入自在にスライド可能になっている。またスライドドア３６の縦方向の端縁部にパッキン３６ａが取付けられ、ドア閉成時における箱型荷物室３２内の気密性を確保している。   The sliding door 36 accommodated in the accommodating portion 34c of the opening / closing door 34 is suspended on a rail provided horizontally above the accommodating portion 34c via a roller (none of which is shown), and can slide freely. It has become. Further, a packing 36a is attached to the longitudinal edge portion of the slide door 36 to ensure the airtightness in the box-type luggage compartment 32 when the door is closed.

［スライド駆動機構について］
前記スライドドア３６のスライド駆動機構３８は、図３に示すように、ベース本体４２と、このベース本体４２に回転自在に支持されたネジ軸４４と、このネジ軸４４を正逆方向へ回転させる回転駆動手段４６と、ネジ軸４４に螺合するナット部材４０とを一纏りのユニットとして構成したものである。ベース本体４２は、前面が開放した箱状をなし、開閉ドア３４の内板３４ａに着脱自在に取付けられる。また、ベース本体４２の開閉ドア３４と当接する面には、前述の長孔３４ｄに対応する開口４２ａが幅方向に開設され、この開口４２ａおよび長孔３４ｄを介してナット部材４０の一部が前記スライドドア３６の裏面に固定される。なお、このベース本体４２としては、必ずしも実施例の如く箱状に形成する必要はなく、例えば、前後面が開放した矩形状枠体であってもよい。 [Slide drive mechanism]
As shown in FIG. 3, the slide drive mechanism 38 of the slide door 36 rotates a base body 42, a screw shaft 44 rotatably supported by the base body 42, and the screw shaft 44 in forward and reverse directions. The rotation drive means 46 and the nut member 40 screwed onto the screw shaft 44 are configured as a unit. The base body 42 has a box shape with an open front surface, and is detachably attached to the inner plate 34a of the open / close door 34. An opening 42a corresponding to the aforementioned long hole 34d is opened in the width direction on the surface of the base body 42 that contacts the opening / closing door 34, and a part of the nut member 40 is formed through the opening 42a and the long hole 34d. It is fixed to the back surface of the slide door 36. The base main body 42 does not necessarily have to be formed in a box shape as in the embodiment, and may be a rectangular frame with open front and rear surfaces, for example.

所要長のネジ軸４４は、その両側がベース本体４２に設けた支持部４２ｂ,４２ｂに回転自在に支持されると共に、図３の右側に位置する支持部４２ｂから延出する一端部は、後述するスプロケット５０ｂを介してモータ４８に連結されている。このネジ軸４４に螺合するナット部材４０は、図１に示すように、開閉ドア３４の裏側に位置し、ネジ軸４４を正逆回転させることで、開放方向および閉成方向へ直線的に往復動し得るようになっている。また、前述のように、ナット部材４０の一部は、ベース本体４２の開口４２ａおよび長孔３４ｄを介してスライドドア３６に固定され、ナット部材４０の移動に伴いスライドドア３６をスライドさせる。すなわち、スライド駆動機構３８は、ネジ軸４４を正逆回転させることでナット部材４０を往復動させ、これにより得られる強い推進力によってスライドドア３６のスライド開閉がなされる。そして、閉成時にスライドドア３６のパッキン３６ａが開口部３２ａの縁部に当接して押圧変形状態となることで、箱型荷物室３２内の気密性が確保される。なお、以下の説明において、スライドドア３６が閉成した状態でのナット部材４０の位置を「閉成位置」、また、スライドドア３６が開放した状態でのナット部材４０の位置を「開放位置」と称する(図３参照)。   The screw shaft 44 of the required length is rotatably supported by support portions 42b, 42b provided on the base body 42, and one end portion extending from the support portion 42b located on the right side in FIG. The sprocket 50b is connected to the motor 48. As shown in FIG. 1, the nut member 40 screwed to the screw shaft 44 is located on the back side of the opening / closing door 34, and linearly moves in the opening direction and the closing direction by rotating the screw shaft 44 forward and backward. It can be reciprocated. Further, as described above, a part of the nut member 40 is fixed to the slide door 36 through the opening 42a and the long hole 34d of the base main body 42, and the slide door 36 is slid as the nut member 40 moves. That is, the slide drive mechanism 38 reciprocates the nut member 40 by rotating the screw shaft 44 forward and backward, and the slide door 36 is opened and closed by the strong propulsive force obtained thereby. When the packing 36a is closed, the packing 36a of the sliding door 36 comes into contact with the edge of the opening 32a so as to be in a pressure-deformed state. In the following description, the position of the nut member 40 when the slide door 36 is closed is “closed position”, and the position of the nut member 40 when the slide door 36 is open is “open position”. (Refer to FIG. 3).

［ネジ軸について］
前記ネジ軸４４としては、一例として８条のネジ溝を有する多条ネジとするのが好ましく、またピッチ(隣り合う溝と溝の距離)は３[ｍｍ]のものを選択した。従って、ネジ軸４４を１回転させてナット部材４０が軸方向に進むリード(距離)Ｌは、Ｌ＝Ｎ×Ｐ(Ｎ:条数,Ｐ:ピッチ)より２４[ｍｍ]となる。このように、大きなリードのネジ軸４４を使用することで、電気系統その他の故障により手でスライドドア３６を開放する必要を生じた際にも、該スライドドア３６に固定したナット部材４０に対し該ネジ軸４４が自由回転(遊転)して、該スライドドア３６の開放を支障なく許容する。なお、大きなリードのネジ軸４４を使用すると、スライドドア３６の完全閉成時に押圧変形したパッキン３６ａの弾性力により該ドア３６が僅かに押し戻され、気密性が低下する畏れがあるので、後述のロック機構５２によりスライドドア３６をロックするのが好ましい。また、ネジ軸４４の代わりに、ボールネジを使用してもよい。 [About screw shaft]
The screw shaft 44 is preferably a multi-threaded screw having 8 thread grooves as an example, and the pitch (distance between adjacent grooves) is 3 [mm]. Therefore, the lead (distance) L in which the nut member 40 advances in the axial direction by rotating the screw shaft 44 once is 24 [mm] from L = N × P (N: number of threads, P: pitch). In this way, when the screw shaft 44 having a large lead is used, even when it becomes necessary to manually open the slide door 36 due to a failure in the electrical system or the like, the nut member 40 fixed to the slide door 36 can be used. The screw shaft 44 freely rotates (swings) and allows the sliding door 36 to be opened without any trouble. If the screw shaft 44 having a large lead is used, the door 36 is slightly pushed back by the elastic force of the packing 36a that is pressed and deformed when the slide door 36 is completely closed, and the airtightness may be lowered. The slide door 36 is preferably locked by the lock mechanism 52. A ball screw may be used instead of the screw shaft 44.

［回転駆動手段について］
ベース本体４２の側方に配設された回転駆動手段４６は、モータ４８および動力伝達機構５０から構成され、これによりネジ軸４４を正逆方向へ回転させるようになっている。モータ４８は、低速・高トルクタイプが好適に採用され、実施例では、回転数１２００[ｒｐｍ]のものを使用した。モータ４８の回転数を低く抑えることにより、モータ作動時の騒音を低下させることが可能となる。また、低速のモータ４８を後述のベルト機構に組合わせることで、歯車式の減速機構を設ける必要がなくなり、スライド駆動機構３８を軽量かつコンパクトにすることができる。更に、歯車式減速機構を使用しないので、保冷室の低温により潤滑グリス等が固まってしまう問題もなくなる。 [Rotation drive means]
The rotation driving means 46 disposed on the side of the base main body 42 includes a motor 48 and a power transmission mechanism 50, and thereby rotates the screw shaft 44 in the forward and reverse directions. The motor 48 is preferably a low-speed / high-torque type. In the embodiment, a motor having a rotational speed of 1200 [rpm] was used. By suppressing the rotational speed of the motor 48 to a low level, it is possible to reduce noise during motor operation. Further, by combining the low-speed motor 48 with a belt mechanism described later, it is not necessary to provide a gear-type reduction mechanism, and the slide drive mechanism 38 can be made lightweight and compact. Furthermore, since no gear type reduction mechanism is used, there is no problem that the lubricating grease or the like is hardened due to the low temperature of the cold insulation chamber.

前記動力伝達機構５０は、モータ４８の回転軸に接続した小径のスプロケット５０ａと、ネジ軸４４の端部に接続した大径のスプロケット５０ｂと、両スプロケット５０ａ,５０ｂ間に介装されたタイミングベルト５０ｃとから構成されている。また、両スプロケット５０ａ,５０ｂの直径差によりその回転比は、例えば、２．７に設定される。すなわち、実施例では、モータ４８の回転数を１２００[ｒｐｍ](＝２０[ｒｐｓ])、スプロケット５０ｂの回転比２．７、ネジ軸４４のリードを２４[ｍｍ]とすることで、スライドドア３６の移動速度が、２０／２．７＊２４＝１７８[ｍｍ／ｓ]となる。但し、以上に示した回転数等の数値は、実施態様に合わせて任意に変更可能である。   The power transmission mechanism 50 includes a small-diameter sprocket 50a connected to the rotating shaft of the motor 48, a large-diameter sprocket 50b connected to the end of the screw shaft 44, and a timing belt interposed between the sprockets 50a and 50b. 50c. The rotation ratio is set to 2.7, for example, due to the difference in diameter between the sprockets 50a and 50b. That is, in the embodiment, the rotational speed of the motor 48 is 1200 [rpm] (= 20 [rps]), the sprocket 50b has a rotation ratio of 2.7, and the lead of the screw shaft 44 is 24 [mm]. The moving speed of 36 is 20 / 2.7 * 24 = 178 [mm / s]. However, the numerical values such as the number of rotations shown above can be arbitrarily changed according to the embodiment.

［ロック機構について］
図３に示すように、ベース本体４２には、スライドドア３６のロックおよびロック解除を行なうロック機構５２が配設されている。前述したように、実施例では、リードの大きいネジ軸４４を使用しているため、スライドドア３６の完全閉成後、パッキン３６ａの弾性力によって該スライドドア３６が僅かに押し戻されてしまう畏れがある。そこで、ロック機構５２により完全閉成後のスライドドア３６をその位置でロックし、開口部３２ａを密閉状態に保持しようとするものである。 [About locking mechanism]
As shown in FIG. 3, the base main body 42 is provided with a lock mechanism 52 that locks and unlocks the slide door 36. As described above, since the screw shaft 44 having a large lead is used in the embodiment, after the sliding door 36 is completely closed, the sliding door 36 may be slightly pushed back by the elastic force of the packing 36a. is there. In view of this, the lock mechanism 52 locks the slide door 36 after being completely closed at that position to hold the opening 32a in a sealed state.

ロック機構５２は、ベース本体４２に揺動自在に軸支されてスライドドア３６をロックするシーソーアーム５４と、該シーソーアーム５４のロックを解除するソレノイド５６とから構成される。シーソーアーム５４は、その中央より僅かに変位した位置を支軸５４ｂにより軸支されて、ベース本体４２に対し揺動自在になっている。シーソーアーム５４の閉成位置側の端部５４ａは、ソレノイド５６のプランジャ５６ａにピン８０を介して連結されている。そして、図５(ａ)に示すように、シーソーアーム５４は、常には端部５４ａが下がった状態にある。   The lock mechanism 52 includes a seesaw arm 54 that is pivotally supported by the base main body 42 and locks the slide door 36, and a solenoid 56 that unlocks the seesaw arm 54. The seesaw arm 54 is pivotally supported by a support shaft 54b at a position slightly displaced from the center thereof, and is swingable with respect to the base body 42. An end portion 54 a on the closed position side of the seesaw arm 54 is connected to a plunger 56 a of a solenoid 56 via a pin 80. As shown in FIG. 5A, the seesaw arm 54 is always in a state where the end 54a is lowered.

前記シーソーアーム５４は、ナット部材４０が閉成方向へ移動する際に、その端部５４ａを時計方向へ押し上げる(図５(ｂ))。そして、ナット部材４０がシーソーアーム５４の端部５４ａ下方を通過して、閉成位置へ到達すると、該シーソーアーム５４は重力によって反時計方向へ揺動し、ナット部材４０と係合してロックが完了する(図５(ｃ))。   When the nut member 40 moves in the closing direction, the seesaw arm 54 pushes up the end 54a in the clockwise direction (FIG. 5B). When the nut member 40 passes below the end 54a of the seesaw arm 54 and reaches the closed position, the seesaw arm 54 swings counterclockwise due to gravity and engages with the nut member 40 to lock. Is completed (FIG. 5C).

ロック解除に際しては、ソレノイド５６に通電すると、プランジャ５６ａが引き上げられ、シーソーアーム５４を時計方向へ揺動させてナット部材４０との係合を離脱させる。但し、スライドドア３６が完全閉成状態にある場合、押圧変形したパッキン３６ａの反発力によってナット部材４０とシーソーアーム５４とは強固に係合しているので、ソレノイド５６に通電してもロックの解除が困難な場合が多い。そこでロックを解除するに先立ち、モータ４８を正回転させてスライドドア３６を更に閉成方向へ移動させ、パッキン３６ａを更に押圧変形させることで、ナット部材４０とシーソーアーム５４との間に作用している強固な係合力を緩和させる。この間にソレノイド５６に通電すれば、容易にロックを解除し得る。なお、前記プランジャ５６ａにはスプリング５６ｃが介装され、該スプリング５６ｃの弾性力によって該プランジャ５６ａを常に下方へ付勢している。従って、悪路を走行中におけるシーソーアーム５４のチャタリングが防止される。   In releasing the lock, when the solenoid 56 is energized, the plunger 56a is pulled up, and the seesaw arm 54 is swung clockwise to disengage the nut member 40 from engagement. However, when the slide door 36 is in a completely closed state, the nut member 40 and the seesaw arm 54 are firmly engaged by the repulsive force of the packing 36a that has been pressed and deformed. It is often difficult to cancel. Therefore, prior to releasing the lock, the motor 48 is rotated forward to further move the slide door 36 in the closing direction, and the packing 36a is further pressed and deformed, thereby acting between the nut member 40 and the seesaw arm 54. Relieve the strong engaging force that is. If the solenoid 56 is energized during this time, the lock can be easily released. A spring 56c is interposed in the plunger 56a, and the plunger 56a is always urged downward by the elastic force of the spring 56c. Accordingly, chattering of the seesaw arm 54 while traveling on a rough road is prevented.

［非常解除手段について］
ベース本体４２の上部には、ロック機構５２のロックを電気的に解除する非常解除ボタン(非常解除手段)５８が設けられている。すなわち、この非常解除ボタン５８を押すことで、ソレノイド５６が通電されてプランジャ５６ａが引き上げられ、シーソーアーム５４とナット部材４０との係合が解除されるようになっている。従って、作業者が箱型荷物室３２内に閉じ込まれてしまった場合でも、箱型荷物室３２内側からロックを解除して外部へ脱出することができる。なお、非常解除ボタン５８を作動させてロックが解除されると、回転駆動手段４６が作動して自動的にスライドドア３６が開放される。 [Emergency cancellation means]
An emergency release button (emergency release means) 58 for electrically releasing the lock of the lock mechanism 52 is provided on the upper portion of the base body 42. That is, when the emergency release button 58 is pressed, the solenoid 56 is energized, the plunger 56a is pulled up, and the engagement between the seesaw arm 54 and the nut member 40 is released. Therefore, even when the worker is closed in the box-type luggage compartment 32, the lock can be released from the inside of the box-type luggage compartment 32 and escape to the outside. When the emergency release button 58 is operated to release the lock, the rotation driving means 46 is operated and the slide door 36 is automatically opened.

［手動解除手段］
ベース本体４２には手動解除手段６０が配設され、これはナット部材４０に係合しているシーソーアーム５４を逆方向へ揺動させて、強制的にスライドドア３６のロックを解除するものである。すなわち、作業者が箱型荷物室３２内に閉じ込まれ、しかも電気系統の故障等によって非常解除ボタン５８が作動しない場合であっても、手動解除手段６０によってロックを強制的に解除して外部へ脱出することができる。この手動解除手段６０は、ベース本体４２に進退自在に螺合されて、その先端をシーソーアーム５４における開放位置側の端部５４ｃに臨ませたボルト６０ｂと、このボルト６０ｂに設けた手回しハンドル６０ａとから構成される。そして、この手回しハンドル６０ａを回転させることによりボルト６０ｂが下降して端部５４ｃを押し下げ、シーソーアーム５４を逆方向へ揺動させるようになっている。なお、この手動解除手段６０については、手動操作によりシーソーアーム５４を強制的に揺動させてロック機構５２を解除し得るものであれば、他の構成を適宜採用可能である。また、手動解除手段６０によってロックを解除した後、作業者は、スライドドア３６を手で開放させて外部に脱出する。 [Manual release means]
The base body 42 is provided with manual release means 60, which forcibly unlocks the slide door 36 by swinging the seesaw arm 54 engaged with the nut member 40 in the reverse direction. is there. That is, even when the worker is closed in the box-type luggage compartment 32 and the emergency release button 58 is not activated due to a failure of the electrical system, the lock is forcibly released by the manual release means 60 and the external Can escape to. The manual release means 60 is screwed to the base body 42 so as to be able to advance and retreat, and a bolt 60b having a tip thereof facing an end 54c on the open position side of the seesaw arm 54, and a handwheel handle 60a provided on the bolt 60b. It consists of. Then, by rotating the handwheel handle 60a, the bolt 60b is lowered to push down the end portion 54c, and the seesaw arm 54 is swung in the reverse direction. As the manual release means 60, other configurations can be appropriately employed as long as the seesaw arm 54 can be forcibly swung manually to release the lock mechanism 52. After releasing the lock by the manual release means 60, the operator opens the slide door 36 by hand and escapes to the outside.

［制御ユニットについて］
前記ベース本体４２の略中央部には、外部送信端末(図示せず)からのスライドドア３６の開閉指令を受信するリモコン受信部６４および回転駆動手段４６の正逆回転制御を行なう回転制御部７０からなる制御ユニット６２がユニット化されて設けられる。リモコン受信部６４は、スライド駆動機構３８とは独立した外部送信端末からの開閉指令を受信して、該開閉指令を回転制御部７０へ送るようになっている。また、回転制御部７０は、リモコン受信部６４からの開閉指令に基づき回転駆動手段４６を正逆回転させるよう構成される。そして、スライドドア３６の開閉を遠隔操作により行ない得るようになっている。なお、外部送信端末による遠隔操作は、スライドドア３６の開閉操作に限られず、例えば、スライドドア３６の非常停止を行ない得るようにしてもよい。また、実施例に係る制御ユニット６２は、回転駆動手段４６の制御だけでなく、ロック機構５２のソレノイド５６をＯＮ・ＯＦＦ制御するようになっている。従って、スライドドア３６の開放指令を受信した場合、または非常解除ボタン５８が押された場合に、制御ユニット６２はソレノイド５６を作動させてスライドドア３６のロックを解除させるようになっている。 [About control unit]
At a substantially central portion of the base body 42, a remote control receiving unit 64 that receives an opening / closing command of the sliding door 36 from an external transmission terminal (not shown) and a rotation control unit 70 that performs forward / reverse rotation control of the rotation driving means 46. A control unit 62 is provided as a unit. The remote control receiving unit 64 receives an open / close command from an external transmission terminal independent of the slide drive mechanism 38 and sends the open / close command to the rotation control unit 70. The rotation control unit 70 is configured to rotate the rotation driving unit 46 forward and backward based on an opening / closing command from the remote control receiving unit 64. The slide door 36 can be opened and closed by remote control. The remote operation by the external transmission terminal is not limited to the opening / closing operation of the slide door 36. For example, the slide door 36 may be emergency-stopped. Further, the control unit 62 according to the embodiment not only controls the rotation driving means 46 but also performs ON / OFF control of the solenoid 56 of the lock mechanism 52. Accordingly, when an opening command for the slide door 36 is received or when the emergency release button 58 is pressed, the control unit 62 operates the solenoid 56 to release the lock of the slide door 36.

前記ベース本体４２の下方には、スライドドア３６の完全開放および完全閉成を検知する検知手段６６が配設されている。この検知手段６６は、ベース本体４２下方の閉成位置に設けられた第１検知センサ６６ａと、同じく開放位置に設けられた第２センサ６６ｂとから構成される。第１センサは、図５(ｃ)に示すように、閉成位置に到達したナット部材４０を検知して、この検知信号により回転制御部７０が回転駆動手段４６を停止させるようになっている。同様に、第２センサ６６ｂは、ナット部材４０が開放位置に到達したのを検知して、回転制御部７０により回転駆動手段４６を停止させるものである。   Below the base body 42, detection means 66 for detecting whether the slide door 36 is fully opened or completely closed is disposed. This detection means 66 is comprised from the 1st detection sensor 66a provided in the closed position under the base main body 42, and the 2nd sensor 66b similarly provided in the open position. As shown in FIG. 5C, the first sensor detects the nut member 40 that has reached the closed position, and the rotation control unit 70 stops the rotation driving means 46 by this detection signal. . Similarly, the second sensor 66b detects that the nut member 40 has reached the open position, and causes the rotation control unit 70 to stop the rotation driving means 46.

更に、前記検知手段６６は、スライドドア３６の完全開放位置(開放位置)より手前の位置を副次的に検知するよう第３センサ６６ｃを備えている。この第３センサ６６ｃは、ベース本体４２に第２センサ６６ｂと隣接するよう設けられ、開放位置に到達する直前のナット部材４０を検知するようになっている。そして、第３センサ６６ｃの検知信号によって、回転制御部７０は回転駆動手段４６を徐々に減速させ、完全開放時にスライドドア３６はゆっくりと停止する。   Further, the detection means 66 includes a third sensor 66c so as to secondaryly detect a position before the fully open position (open position) of the slide door 36. The third sensor 66c is provided on the base body 42 so as to be adjacent to the second sensor 66b, and detects the nut member 40 immediately before reaching the open position. Then, according to the detection signal of the third sensor 66c, the rotation control unit 70 gradually decelerates the rotation driving means 46, and the slide door 36 stops slowly when fully opened.

(実施例の作用)
次に、実施例に係る車両用扉の開閉構造の作用について説明する。なお、当初のスライドドア３６は完全閉成状態にあるものとする。スライドドア３６を開放させる際には、外部送信端末を操作して開放指令を送信する。この開放指令をリモコン受信部６４が受信すると、先ず始めに、制御ユニット６２は回転駆動手段４６を作動させてスライドドア３６を閉成方向へ僅かに移動させ、シーソーアーム５４とナット部材４０との係合を緩和させる。そして、この間にソレノイド５６を作動させてプランジャ５６ａを引き上げ、スライドドア３６のロックを解除する。 (Operation of Example)
Next, the operation of the vehicle door opening and closing structure according to the embodiment will be described. It is assumed that the initial slide door 36 is in a completely closed state. When the slide door 36 is opened, an open command is transmitted by operating the external transmission terminal. When the remote control receiving unit 64 receives this opening command, first, the control unit 62 operates the rotation driving means 46 to slightly move the slide door 36 in the closing direction, so that the seesaw arm 54 and the nut member 40 are moved. Relieve engagement. During this time, the solenoid 56 is operated to pull up the plunger 56a to release the lock of the slide door 36.

次に、前記開閉指令は回転制御部７０へ送られて、該制御部７０は回転駆動手段４６を逆方向へ回転させる。これによりネジ軸４４は逆方向へ回転されてナット部材４０が開放方向へ移動し、スライドドア３６の開放が始まる(図４(ａ))。そして、スライドドア３６が完全開放する直前になって、ナット部材４０が第３センサ６６ｃ上を通過すると、該センサ６６ｃはこれを検知する。第３センサ６６ｃの検知信号は回転制御部７０へ送られて、該制御部７０は回転駆動手段４６を徐々に減速させ、スライドドア３６の移動速度を下げる。   Next, the opening / closing command is sent to the rotation control unit 70, and the control unit 70 rotates the rotation driving means 46 in the reverse direction. As a result, the screw shaft 44 is rotated in the opposite direction, the nut member 40 moves in the opening direction, and the opening of the slide door 36 begins (FIG. 4A). When the nut member 40 passes over the third sensor 66c just before the sliding door 36 is fully opened, the sensor 66c detects this. The detection signal of the third sensor 66c is sent to the rotation control unit 70, and the control unit 70 gradually decelerates the rotation driving means 46 and lowers the moving speed of the slide door 36.

更に、図４(ｂ)に示すように、スライドドア３６が完全開放状態となって、ナット部材４０が開放位置に到達すると、第２センサ６６ｂがこれを検知して、回転制御部７０は回転駆動手段４６を停止させる。この時、スライドドア３６は減速されているので、静かに停止して騒音やビビリが生じることがない。更に、スライドドア３６を徐々に減速させて停止させることにより、前記タイミングベルト５０ｃに掛かる負荷が低減されて、該ベルト５０ｃの損耗を防止し得る。   Further, as shown in FIG. 4B, when the slide door 36 is fully opened and the nut member 40 reaches the open position, the second sensor 66b detects this, and the rotation control unit 70 rotates. The driving means 46 is stopped. At this time, since the slide door 36 is decelerated, the slide door 36 is quietly stopped and no noise or chatter occurs. Further, by gradually decelerating and stopping the slide door 36, the load applied to the timing belt 50c can be reduced, and wear of the belt 50c can be prevented.

そして、作業者は、図４(ｃ)に示すように、開閉ドア３４を手動で開放して開口部３２ａを完全に開放し、荷物の積込み作業等を行なう。なお、図４(ｂ)に示すように、スライドドア３６のみ開放した状態で積込み作業を行なうことも可能である。   Then, as shown in FIG. 4C, the operator manually opens the opening / closing door 34 to completely open the opening 32a, and loads the cargo. As shown in FIG. 4B, the loading operation can be performed with only the sliding door 36 opened.

荷物の積込みが終了して、車両用扉３０を閉成させる際には、先ず、開閉ドア３４を手動で閉成させた後(図４(ｂ))、外部送信端末からスライドドア３６の閉成指令を送信する。この閉成指令は、リモコン受信部６４を介して回転制御部７０へ送られて、回転駆動手段４６が正方向へ回転される。これにより、ナット部材４０が閉成方向へ移動してスライドドア３６のスライドが開始する。   When the loading of the luggage is completed and the vehicle door 30 is closed, first, the open / close door 34 is manually closed (FIG. 4B), and then the slide door 36 is closed from the external transmission terminal. Send the creation command. This closing command is sent to the rotation control unit 70 via the remote control receiving unit 64, and the rotation driving means 46 is rotated in the forward direction. Thereby, the nut member 40 moves in the closing direction, and the sliding of the slide door 36 starts.

ナット部材４０が閉成方向へ移動して、図５(ｂ)に示すように、シーソーアーム５４に当接すると、ナット部材４０はシーソーアーム５４の端部５４ａを時計方向へ押し上げつつ移動する。更に、ナット部材４０がシーソーアーム５４を通過して閉成位置に到達すると、前記第１センサ６６ａがこれを検知し、回転制御部７０は回転駆動手段４６を停止させる。これと同時に、シーソーアーム５４の端部５４ａは重力によって反時計方向へよって下がり、ナット部材４０と係合してロックが完了する(図５(ｃ))。すなわち、ナット部材４０の強い推進力によって、スライドドア３６のパッキン３６ａが押圧変形状態となるまで開口部３２ａは強力に密閉される。更にこの状態で、直ちにスライドドア３６がロックされるので、パッキン３６ａの反発力によって該ドア３６が移動することなく、密閉状態を保持し得る。   When the nut member 40 moves in the closing direction and contacts the seesaw arm 54 as shown in FIG. 5B, the nut member 40 moves while pushing up the end 54a of the seesaw arm 54 in the clockwise direction. Further, when the nut member 40 passes through the seesaw arm 54 and reaches the closed position, the first sensor 66a detects this, and the rotation control unit 70 stops the rotation driving means 46. At the same time, the end 54a of the seesaw arm 54 is lowered counterclockwise due to gravity, and engages with the nut member 40 to complete the locking (FIG. 5C). That is, the opening 32a is tightly sealed until the packing 36a of the slide door 36 is pressed and deformed by the strong propulsive force of the nut member 40. Furthermore, since the slide door 36 is immediately locked in this state, the sealed state can be maintained without the door 36 moving due to the repulsive force of the packing 36a.

なお、外部送信端末を所持していない作業者が、何らかの原因によりスライドドア３６が閉じて箱型荷物室３２内に閉じ込まれてしまうと、該荷物室３２内は低温なため、作業者にとって非常に危険である。このような場合には、非常解除ボタン５８を押すことでスライドドア３６のロックを解除することができる。すなわち、作業者が非常解除ボタン５８を押すと、制御ユニット６２はソレノイド５６を作動させてプランジャ５６ａを引き上げ、シーソーアーム５４とナット部材４０との係合を解除する。その後、制御ユニット６２は回転駆動手段４６を逆回転させてスライドドア３６を自動的に開放し、作業者は外部へ脱出することが可能となる。   If an operator who does not have an external transmission terminal closes the slide door 36 for some reason and closes it into the box-type luggage compartment 32, the inside of the luggage compartment 32 is low in temperature. Very dangerous. In such a case, the slide door 36 can be unlocked by pressing the emergency release button 58. That is, when the operator presses the emergency release button 58, the control unit 62 operates the solenoid 56 to pull up the plunger 56a and release the engagement between the seesaw arm 54 and the nut member 40. Thereafter, the control unit 62 reversely rotates the rotation driving means 46 to automatically open the slide door 36, and the operator can escape to the outside.

更に、上記の場合において、電気系統等の故障によって非常解除ボタン５８を使用することができない場合には、作業者は手動解除手段６０によりロック機構５２を強制的に解除することが可能となる。すなわち、作業者が手回しハンドル６０ａを回転させて、手動解除手段６０を下降させる。すると、ボルト６０ｂはシーソーアーム５４の端部５４ｃを時計方向へ押し下げて、シーソーアーム５４とナット部材４０との係合が強制的に解除される。ロックを解除した後、作業者は手動でスライドドア３６を開放させて外部へ脱出することができる。この時、ネジ軸４４はリードの大きいなものが使用されているので、スライドドア３６は支障なく開放させることが可能である。   Further, in the above case, when the emergency release button 58 cannot be used due to a failure in the electrical system or the like, the operator can forcibly release the lock mechanism 52 by the manual release means 60. That is, the operator manually turns the handle 60a to lower the manual release means 60. Then, the bolt 60b pushes down the end portion 54c of the seesaw arm 54 in the clockwise direction, and the engagement between the seesaw arm 54 and the nut member 40 is forcibly released. After releasing the lock, the operator can manually open the slide door 36 and escape to the outside. At this time, since the screw shaft 44 having a large lead is used, the slide door 36 can be opened without any trouble.

以上に示したように、実施例に係る車両用扉の開閉構造によれば、ネジ軸４４に螺合したナット部材４０が往復動することでスライドドア３６を開閉するよう構成したので、スライドドア３６の推進力が大幅に向上して、開口部３２ａを充分に密閉することができる。従って、内部の冷気が漏れることがなく、エネルギー効率が向上される。また、ロック機構５２や制御ユニット６２、検知手段６６等は、ベース本体４２にユニット化されているので、取付作業が容易となって、外部電源との配線も極めてシンプルにすることができる。更に、実施例では、制御ユニット６２をリモコン受信部６４と回転制御部７０とから構成したので、スライドドア３６の開閉を遠隔操作で行なうことが可能となり、配送作業の能率が向上される。   As described above, according to the opening / closing structure of the vehicle door according to the embodiment, the slide door 36 is opened and closed by the reciprocating movement of the nut member 40 screwed to the screw shaft 44. The propulsive force of 36 is greatly improved, and the opening 32a can be sufficiently sealed. Therefore, internal cold air does not leak and energy efficiency is improved. Further, since the lock mechanism 52, the control unit 62, the detection means 66, and the like are unitized in the base body 42, the mounting work is facilitated and the wiring with the external power source can be extremely simplified. Furthermore, in the embodiment, since the control unit 62 includes the remote control receiving unit 64 and the rotation control unit 70, the sliding door 36 can be opened and closed by remote operation, and the efficiency of delivery work is improved.
