Description

本発明は、ウィンドウレギュレータのワイヤドラム支持構造に関する。   The present invention relates to a wire drum support structure for a window regulator.

自動車のサイドウィンドウを開閉する装置として、ワイヤ式のウィンドウレギュレータが知られている。
このウィンドウレギュレータは、ウィンドウガラスの昇降方向に沿ってガイドレールを配置し、ガイドレールの上下端部に装着したガイドプーリにワイヤを掛け回すと共に、ガイドレールに沿って摺動するキャリアプレートをワイヤに固定し、キャリアプレートでウィンドウガラスの下端を支持し、ワイヤをワイヤドラムで巻き取り・巻き戻すことによりウィンドウガラスを昇降させるようになっている。
As a device for opening and closing a side window of an automobile, a wire type window regulator is known.
In this window regulator, guide rails are arranged along the raising and lowering direction of the window glass, and wires are wound around guide pulleys mounted on the upper and lower ends of the guide rails, and carrier plates that slide along the guide rails are used as wires. The window glass is moved up and down by fixing, supporting the lower end of the window glass with a carrier plate, and winding and rewinding the wire with a wire drum.

このようなウィンドウレギュレータのワイヤドラムは、電動モータ、ギヤ等から成る駆動部に連絡されると共に、ワイヤドラムの中心とその外面を覆うケーシングに設けた軸受けとを凹凸嵌合することにより、回動自在に支持されていることが多い(特許文献1及び特許文献2参照)。
しかし、ワイヤドラムの中心を支持するケーシングの設置位置がずれると、ワイヤドラムの回転中心がぶれてしまうので、ケーシングのベース等に対する固定箇所及びワイヤドラム支持部は精密に位置決めしなければならず、このため、部材加工及び組み立てに手間がかかった。
The wire drum of such a window regulator is connected to a drive unit composed of an electric motor, a gear, etc., and is rotated by engaging the center of the wire drum with a bearing provided on a casing covering the outer surface thereof. Often supported freely (see Patent Document 1 and Patent Document 2).
However, if the installation position of the casing that supports the center of the wire drum is shifted, the rotation center of the wire drum is shaken, so the fixing location for the base of the casing and the wire drum support must be positioned precisely, For this reason, it took time and effort to process and assemble the members.

本発明が解決しようとする課題は、ワイヤドラム、ワイヤドラムを駆動するギヤ及びケーシングの中心合わせが容易で、ワイヤドラムの回転中心のずれを防ぐウィンドウレギュレータのワイヤドラム支持構造を提供することにある。   The problem to be solved by the present invention is to provide a wire drum support structure for a window regulator that can easily align the center of a wire drum, a gear that drives the wire drum, and a casing, and that prevents the rotation center of the wire drum from shifting. .

本発明のウィンドウレギュレータのワイヤドラム支持構造は、ワイヤ巻取り・巻き戻し用のワイヤドラムをケーシング内に収納し、前記ワイヤドラムの中心に透孔を形成し、前記ワイヤドラムを回動駆動させるギヤを中心軸の周囲に回動自在に嵌合し、前記ワイヤドラムの透孔の内周面と前記ギヤの外周面とを噛合し、前記ケーシングの内面に、前記ワイヤドラムを回動自在に支持する筒部を突設し、該筒部を前記ワイヤドラムの透孔へ挿入すると共に、前記中心軸に外嵌してある。   A wire drum support structure for a window regulator according to the present invention includes a wire drum for winding and unwinding a wire in a casing, a through hole is formed in the center of the wire drum, and the gear for rotating the wire drum. Is rotatably fitted around the central axis, the inner peripheral surface of the through hole of the wire drum is engaged with the outer peripheral surface of the gear, and the wire drum is rotatably supported on the inner surface of the casing. A cylindrical portion to project is provided, and the cylindrical portion is inserted into the through hole of the wire drum and is externally fitted to the central shaft.

本発明によれば、筒部を中心軸に外嵌するだけでワイヤドラム、ケーシング及びギヤを簡単に、且つ、正確に中心合わせすることができるので、ワイヤドラムの回転芯がずれる心配がなく、また、ケーシングの固定箇所及び筒部の位置も高度な寸法精度を要求されないため、部材加工及び組み立ての手間が軽減される。
さらに、ギヤを支持する中心軸を利用して、ケーシングの位置決めを行なうので、構造が簡単で済む。
According to the present invention, the wire drum, the casing, and the gear can be easily and accurately centered simply by fitting the tube portion around the central axis, so there is no fear that the rotation center of the wire drum will shift. In addition, since the location where the casing is fixed and the position of the cylindrical portion are not required to have a high degree of dimensional accuracy, the labor of member processing and assembly can be reduced.
Further, since the casing is positioned using the central shaft that supports the gear, the structure is simple.

以下、本発明の実施例を図面に基づいて詳細に説明する。
本発明のウィンドウレギュレータは、自動車のドアパネルに内蔵され、図1に示すように、ウィンドウガラスの昇降方向に沿って配置した前後一対のガイドレール1と、電動モータの出力軸に減速器を介して連絡されたワイヤドラム2と、ワイヤドラム2に巻き回され、ガイドレール1の裏面上下端部にそれぞれ設置したガイドプーリ3間に架設されたワイヤ4と、前後のガイドレール1にそれぞれ摺動自在に係合し、ウィンドウガラスの下部に固定されたキャリアプレート5とを備える。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The window regulator of the present invention is built in a door panel of an automobile, and, as shown in FIG. 1, a pair of front and rear guide rails 1 arranged along the raising / lowering direction of the window glass, and an output shaft of the electric motor via a speed reducer. The contacted wire drum 2, the wire 4 wound around the wire drum 2 and installed between the guide pulleys 3 installed on the upper and lower ends of the back surface of the guide rail 1, and the front and rear guide rails 1 are slidable. And a carrier plate 5 fixed to the lower part of the window glass.

ワイヤ4は、一方のキャリアプレート5から一方のガイドレール1の上端に装着されたガイドプーリ3を通過し、他方のガイドレール1の下端部に装着したガイドプーリ3を経て、他方のキャリアプレート5に達し、さらに、他方のキャリアプレート5から他方のガイドレール1の上端に装着されたガイドプーリ3を通過し、一方のガイドレール1の下端部に装着したガイドプーリ3を経て、一方のキャリアプレート5に達している。
そして、ワイヤ4は前後のガイドレール1の間で交差しており、ワイヤドラム2を回転させるとワイヤ4のガイドレール1に沿う部分は上下方向に移動する。この結果、ワイヤ4に固定されたキャリアプレート5は同時にガイドレール1に沿って移動し、ウィンドウガラスが昇降する。
The wire 4 passes through the guide pulley 3 attached to the upper end of one guide rail 1 from one carrier plate 5, passes through the guide pulley 3 attached to the lower end portion of the other guide rail 1, and then passes through the other carrier plate 5. Furthermore, it passes through the guide pulley 3 mounted on the upper end of the other guide rail 1 from the other carrier plate 5, passes through the guide pulley 3 mounted on the lower end portion of the one guide rail 1, and then passes through the guide pulley 3. 5 has been reached.
And the wire 4 cross | intersects between the front and back guide rails 1, and when the wire drum 2 is rotated, the part along the guide rail 1 of the wire 4 will move to an up-down direction. As a result, the carrier plate 5 fixed to the wire 4 simultaneously moves along the guide rail 1 and the window glass moves up and down.

図1及び図2に示すように、電動モータ、減速器、ワイヤドラム2、及び、ワイヤドラム2が収納されたケーシング6はベース11上に設置され、ケーシング6はベース11にネジ等により固定されている。
図2に示すように、ワイヤドラム2の中心には、断面円形で内周面に多数の歯を有する透孔7が軸方向に沿って形成されている。
また、ワイヤドラム2の透孔7には、減速器の末端に位置するギヤ8が嵌合され、ワイヤドラム2の透孔7の内周面とギヤ8の外周面とが噛み合っている。
As shown in FIGS. 1 and 2, the electric motor, the speed reducer, the wire drum 2, and the casing 6 in which the wire drum 2 is housed are installed on the base 11, and the casing 6 is fixed to the base 11 with screws or the like. ing.
As shown in FIG. 2, a through hole 7 having a circular cross section and a large number of teeth on the inner peripheral surface is formed in the center of the wire drum 2 along the axial direction.
A gear 8 located at the end of the speed reducer is fitted in the through hole 7 of the wire drum 2, and the inner peripheral surface of the through hole 7 of the wire drum 2 and the outer peripheral surface of the gear 8 are engaged with each other.

ギヤ8は中心軸9の周囲に回動自在に嵌合され、この中心軸9がギヤ8を貫通して突出すると共に、ワイヤドラム2の透孔7に挿入されている。
ケーシング6の内面には断面円形の筒部10が突設される。この筒部10は、ワイヤドラム2を回動自在に支持する軸受けとなっており、ワイヤドラム2の透孔7に挿入されている。
また、筒部10の先端部は、ギヤ8から突出した中心軸9に外嵌している。
筒部10を中心軸9に外嵌することにより、ケーシング6はギヤ8及びワイヤドラム2に対して正確な位置に設置されるので、ケーシング6とベース11との固定箇所を精密に位置決めしなくても良い。
The gear 8 is rotatably fitted around the central shaft 9, and the central shaft 9 protrudes through the gear 8 and is inserted into the through hole 7 of the wire drum 2.
A cylindrical portion 10 having a circular cross section is provided on the inner surface of the casing 6. The cylindrical portion 10 is a bearing that rotatably supports the wire drum 2, and is inserted into the through hole 7 of the wire drum 2.
Further, the distal end portion of the cylindrical portion 10 is externally fitted to the central shaft 9 protruding from the gear 8.
Since the casing 6 is externally fitted to the central shaft 9, the casing 6 is installed at an accurate position with respect to the gear 8 and the wire drum 2, so that the fixing location between the casing 6 and the base 11 is not precisely positioned. May be.

電動モータを駆動すると、減速器の末端に位置したギヤ8が中心軸9の周囲を回動し、ギヤ8と噛み合ったワイヤドラム2が筒部10の周囲を回動する。
この時、筒部10は中心軸9に外嵌されているので、ギヤ8の回転中心となる中心軸9と、ワイヤドラム2の回転中心となる筒部10とが位置ずれすることはない。
そして、ワイヤドラム2は回動に伴ってワイヤ4を巻取り或いは巻き戻し、これにより、ウィンドウガラスが昇降する。
When the electric motor is driven, the gear 8 positioned at the end of the speed reducer rotates around the central shaft 9, and the wire drum 2 meshed with the gear 8 rotates around the cylindrical portion 10.
At this time, since the cylindrical portion 10 is fitted on the central shaft 9, the central shaft 9 that is the rotational center of the gear 8 and the cylindrical portion 10 that is the rotational center of the wire drum 2 are not displaced.
And the wire drum 2 winds up or rewinds the wire 4 with rotation, and thereby the window glass moves up and down.
