Description

本発明は、車両のドアの窓ガラスを昇降させるウインドレギュレータ及びウインドレギュレータの製造方法に関する。 The present invention relates to a window regulator for raising and lowering a window glass of a vehicle door and a method of manufacturing the window regulator.

従来、車両のドアには、モータの駆動力により窓ガラスを昇降させるウインドレギュレータが用いられている（例えば、特許文献１参照）。 2. Description of the Related Art Conventionally, a window regulator that raises and lowers a window glass by a driving force of a motor has been used for a door of a vehicle (for example, see Patent Document 1).

特許文献１に記載のウインドレギュレータは、開閉体としての窓ガラスの移動方向に沿ってドアインナパネルに固定されたガイドレールと、ガイドレールの長手方向に沿って架張されたワイヤと、ガイドレールに案内されて窓ガラスと共に移動するキャリアと、ワイヤを介してキャリアを駆動する駆動部とを備えている。 The window regulator described in Patent Literature 1 includes a guide rail fixed to a door inner panel along a moving direction of a window glass as an opening and closing body, a wire stretched along a longitudinal direction of the guide rail, and a guide rail. And a driving unit for driving the carrier via a wire, the carrier being guided along with the window glass and moving with the window glass.

駆動部は、ワイヤが外周面に巻き回されたドラムと、ドラムを回転させるモータとを有している。また、ガイドレールの上端部にはワイヤを方向変換するプーリが配置され、ガイドレールの下端部には、同じくワイヤを方向変換する半円状ガイドが配置されている。ワイヤは、その両端部がキャリアに固定されると共に、プーリ及び半円状ガイドで方向変換され、プーリと半円状ガイドとの間でドラムに巻き回されている。 The drive unit includes a drum having a wire wound around the outer peripheral surface, and a motor for rotating the drum. A pulley for changing the direction of the wire is arranged at the upper end of the guide rail, and a semicircular guide for changing the direction of the wire is arranged at the lower end of the guide rail. Both ends of the wire are fixed to the carrier, the direction of the wire is changed by a pulley and a semicircular guide, and the wire is wound around a drum between the pulley and the semicircular guide.

ワイヤの両端部は、弛み除去用スプリングを介してキャリアに固定されている。これにより、ワイヤに張力が付与されている。ワイヤは上昇用ワイヤと下降用ワイヤとからなる。上昇用ワイヤはドラムからプーリを経てキャリアに至って配策され、下降用ワイヤはドラムから半円状ガイドを経てキャリアに至って配策される。キャリアの上昇時にはモータが正回転して駆動部が上昇用ワイヤを巻き取ると共に下降用ワイヤを繰り出す。また、キャリアの下降時にはモータが逆回転して駆動部が下降用ワイヤを巻き取ると共に上昇用ワイヤを繰り出す。これにより、窓ガラスがキャリアと共に上下方向に移動する。 Both ends of the wire are fixed to the carrier via a slack removing spring. Thereby, tension is applied to the wire. The wire is composed of an ascending wire and a descending wire. The ascending wire is routed from the drum via the pulley to the carrier, and the descending wire is routed from the drum via the semicircular guide to the carrier. When the carrier is lifted, the motor rotates forward and the drive unit winds up the wire for raising and unwinds the wire for lowering. When the carrier is lowered, the motor rotates in the reverse direction, and the driving unit winds the lowering wire and unwinds the raising wire. Thereby, the window glass moves in the vertical direction together with the carrier.

FIG. 1 illustrates a state where the door at the right rear seat is viewed from the outside of the vehicle. In FIG. 1, the outline of the door and the window frame are indicated by imaginary lines (two-dot chain line), and the portion arranged inside the window glass of the window regulator (on the side of the passenger compartment) is indicated by broken lines.

このウインドレギュレータ１は、車両のドア９に設けられ、ドア９の窓ガラス９０を昇降させる。窓ガラス９０は、図略のガラスガイドに案内され、上下方向に移動する。なお、図１では、一例としてウインドレギュレータ１を車両の右後席のドアに用いた場合を図示しているが、車両における他のドアにウインドレギュレータ１を設けることも可能である。 The window regulator 1 is provided on a door 9 of a vehicle, and raises and lowers a window glass 90 of the door 9. The window glass 90 is guided by a glass guide (not shown) and moves vertically. Although FIG. 1 shows an example in which the window regulator 1 is used for a right rear door of a vehicle, the window regulator 1 may be provided on another door of the vehicle.

ウインドレギュレータ１は、窓ガラス９０の移動方向に沿って配置されるガイドレール２０と、ガイドレール２０の長手方向に沿って架張されたワイヤ３と、ガイドレール２０に案内されて窓ガラス９０と共に移動する移動体４とを備えている。移動体４は、ワイヤ３の一部が巻き回されたドラム４０（後述する図４に示す）と、ドラム４０を回転駆動する駆動力を発生するモータ５と、ドラム４０及びモータ５を保持するハウジング６と、ハウジング６に窓ガラス９０を結合する結合部材７１，７２とを有している。移動体４の構成の詳細については後述する。 The window regulator 1 includes a guide rail 20 arranged along the moving direction of the window glass 90, a wire 3 stretched along the longitudinal direction of the guide rail 20, and the window glass 90 guided by the guide rail 20.

The first guide groove 611 is formed above the accommodation space 61a, and opens toward the first wire support member 21. The second guide groove 612 is formed below the accommodation space 61a, and opens toward the second wire support member 22. The first guide groove 611 and the second guide groove 612 are formed at positions closer to the guide rail 20 side than the center of the accommodation space 61a.

また、ドラムハウジング６１には、車両の前後方向の両端部に貫通孔６１３，６１４が形成されている。この貫通孔６１３，６１４をそれぞれ挿通するボルト７１１，７１２（図１に示す）によって、ドラムハウジング６１に結合部材７１，７２が固定される。 Further, through holes 613 and 614 are formed in the drum housing 61 at both ends in the front-rear direction of the vehicle. The coupling members 71 and 72 are fixed to the drum housing 61 by bolts 711 and 712 (shown in FIG. 1) inserted through the through holes 613 and 614, respectively.

On the inner peripheral surface of the center hole 42 of the drum 40, an inner peripheral spline 42a extending in the axial direction of the drum 40 is formed.

ワイヤ３は、第１のワイヤ支持部材２１及び第２のワイヤ支持部材２２に保持された弾性体としてのバネ２３，２４（図３（ａ）に示す）により張力を付与されている。これにより、ワイヤ３は、第１のワイヤ支持部材２１と第２のワイヤ支持部材２２との間において弛むことなく架張されている。 The wire 3 is tensioned by springs 23 and 24 (shown in FIG. 3A) as elastic bodies held by a first wire support member 21 and a second wire support member 22. Thereby, the wire 3 is stretched without loosening between the first wire support member 21 and the second wire support member 22.

ワイヤ３の配策経路を、第１のワイヤ支持部材２１側の端部を始点とし、第２のワイヤ支持部材２２側の端部を終点として説明すると、第１のワイヤ支持部材２１から導出されたワイヤ３は、ガイドレール２０に沿って下方に延び、ドラムハウジング６１の第１ガイド溝６１１を経由して収容空間６１ａ内に導かれる。収容空間６１ａ内に導かれたワイヤ３は、ドラム４０の溝４１に収容されてドラム４０の外周面を複数回にわたって周回し、第２ガイド溝６１２を経由してドラムハウジング６１の外部に導出される。第２ガイド溝６１２から導出されたワイヤ３は、ガイドレール２０に沿って下方に延びて第２のワイヤ支持部材２２に支持される。 When the route of the wire 3 is described with the end on the first wire support member 21 side as a start point and the end on the second wire support member 22 side as an end point, the route is derived from the first wire support member 21. The wire 3 extends downward along the guide rail 20 and is guided into the accommodation space 61 a via the first guide groove 611 of the drum housing 61. The wire 3 guided into the housing space 61a is housed in the groove 41 of the drum 40, orbits the outer peripheral surface of the drum 40 a plurality of times, and is led out of the drum housing 61 via the second guide groove 612. You. The wire 3 led out from the second guide groove 612 extends downward along the guide rail 20 and is supported by the second wire support member 22.

第１のワイヤ支持部材２１とドラムハウジング６１との間におけるワイヤ３を上部ワイヤ３ａとし、第２のワイヤ支持部材２２とドラムハウジング６１との間におけるワイヤ３を下部ワイヤ３ｂとすると、ドラム４０の回転により、上部ワイヤ３ａ及び下部ワイヤ３ｂの長さが変化する。つまり、移動体４の上昇時におけるドラム４０の回転方向を正方向とし、移動体４の下降時におけるドラム４０の回転方向を逆方向とすると、ドラム４０が正方向に回転することにより、上部ワイヤ３ａの長さが短くなると共に下部ワイヤ３ｂの長さが長くなる。また、ドラム４０が逆方向に回転することにより、上部ワイヤ３ａの長さが長くなると共に下部ワイヤ３ｂの長さが短くなる。この上部ワイヤ３ａ及び下部ワイヤ３ｂの長さの変化に応じて、移動体４がガイドレール２０に対して上下方向に移動する。 If the wire 3 between the first wire support member 21 and the drum housing 61 is an upper wire 3a, and the wire 3 between the second wire support member 22 and the drum housing 61 is a lower wire 3b, The rotation changes the lengths of the upper wire 3a and the lower wire 3b. That is, if the rotation direction of the drum 40 when the moving body 4 is raised is the forward direction and the rotation direction of the drum 40 when the moving body 4 is lowered is the reverse direction, the upper wire is rotated by the drum 40 rotating in the forward direction. The length of the lower wire 3b increases as the length of the lower wire 3a decreases. When the drum 40 rotates in the opposite direction, the length of the upper wire 3a increases and the length of the lower wire 3b decreases. The moving body 4 moves vertically with respect to the guide rail 20 in accordance with the change in the length of the upper wire 3a and the lower wire 3b.

モータ５は、コネクタ部５ａから供給される電流によって回転駆動力を発生する直流モータである。モータ５の回転子には、ギヤハウジング６２の筒部６２０に収容された図略のウォームが一体に回転するように連結されている。モータ５の回転は、ギヤハウジング６２に収容されたウォームギヤ機構によって減速され、ウォームギヤ機構の出力軸を介してドラム４０に伝達される。 The motor 5 is a DC motor that generates a rotational driving force by a current supplied from the connector unit 5a. A worm (not shown) accommodated in the cylindrical portion 620 of the gear housing 62 is connected to the rotor of the motor 5 so as to rotate integrally. The rotation of the motor 5 is reduced by the worm gear mechanism housed in the gear housing 62 and transmitted to the drum 40 via the output shaft of the worm gear mechanism.
