[0014]
As shown in FIGS. 3 and 4, the guide roller unit 5 includes a base plate 51, inner and outer rollers 52 and 53, and upper and lower rollers 54. The base plate 51 roughly includes a vertical wall 51a (first vertical wall), a horizontal wall 51b (horizontal wall), and a vertical wall 51c (second vertical wall). A flange 51d is formed at the upper end of the vertical wall 51a so as to bend and extend in the horizontal direction in the vehicle rear direction (vertical front direction in FIG. 3). A horizontal wall 51b is formed from the lower end of the vertical wall 51a so as to bend and extend inward and rearward of the vehicle. On the horizontal wall 51b, an upper step portion 51e, a middle step portion 51f, and a lower step portion 51g having different heights are formed so as to be smoothly connected in a downward step shape. A bracket 11 fixed to the slide door 1 is fixed between the flange portion 51d and the upper step portion 51e via a pin 12 so as to be relatively rotatable. In other words, the base plate 51 is supported by the bracket 11 so as to be relatively rotatable. That is, the guide rail unit 5 is swingably supported by the slide door 1. A rectangular opening 51k (storage recess) that opens in the vehicle vertical direction is formed in the lower step 51g. A movable pulley mechanism 8 (described later) is disposed in the opening 51k. Further, a vertical wall 51c is formed at the vehicle inner end of the lower step portion 51g so as to bend and extend from the vehicle inner end of 51g in the vehicle upward direction. The vertical wall 51 c is located between the recess 22 and the guide cover 24. A pair of arms 51m and 51n are formed at the upper end of the vertical wall 51c so as to bend and extend horizontally in the vehicle interior direction. Inner and outer rollers 52 and 53 are rotatably supported at the tips of the pair of arms 51m and 51n. The inner and outer rollers 52 and 53 are in sliding contact with the flange wall 31d and the vertical wall 31a of the center guide rail 3. In addition, an upper and lower roller 54 is rotatably supported on the vertical wall 51 c, and the upper and lower roller 54 is in sliding contact with the lower wall 31 c of the center guide rail 3. As a result, the guide roller unit 5 is slidably guided on the roller guide rail 31 in the vehicle vertical direction and in the vehicle interior / exterior direction without rattling. The guide roller unit 5 slidably guided by the upper and lower guide rails 41 and 42 has the same configuration. As a result, the slide door 1 is slidably supported by the side body 2 via the guide rails 3, 41 and 42 by the guide roller unit 5. The guide roller 5 slides with respect to the guide rails 3, 41, 42 by a power slide unit (described later), so that the slide door 1 slides with respect to the side body 2.
[0015]
Next, a power slide unit that slides the slide door 1 with respect to the side body 2 will be described with reference to FIGS.
[0016]
As shown in FIG. 1, the power slide unit mainly includes a drive mechanism 6 (drive mechanism), a cable 7 (cable), a movable pulley mechanism 8, and an intermediate pulley mechanism 9.
[0017]
The drive mechanism 6 is disposed in the slide door 1 and is fixed to the door panel of the slide door 1 via a bracket or the like. The drive mechanism 6 includes a motor 61 as a drive source and a rotatable output drum 62. The output drum 62 (output drum) is connected to the output shaft of the motor 61 through a reduction gear structure (not shown), and rotates in one direction and the other direction by forward and reverse rotation of the motor 61.
[0018]
The cable 7 is composed of two wires 71 and 72. One end of each of the wires 71 and 72 is wound around the output drum 62. As shown in FIGS. 1 and 2, the wire 71 is routed in the center guide rail 3 while being guided by the intermediate pulley mechanism 9 and the movable pulley mechanism 8 in the slide door 1. The other end (not shown) of the wire 71 is locked near the front end of the center guide rail 3 in the vehicle front-rear direction. The wire 72 is also routed in the center guide rail 3 by being guided by the intermediate pulley mechanism and the movable pulley mechanism 8 in the slide door 1. The other end (not shown) of the wire is locked near the rear end of the center guide rail 3 in the vehicle front-rear direction. The cable 7 may be composed of a single wire that is wound around the output drum 61 and is engaged with a predetermined portion on the vehicle body side instead of the two wires 71 and 72. Further, the other ends of the wires 71 and 72 may be locked at any position other than the above-described portions as long as the front and rear ends of the sliding range of the sliding door 1 in the vehicle front-rear direction are on the vehicle body side.
[0019]
As shown in FIGS. 1, 5, and 6, the intermediate pulley mechanism 9 is fixed to the vehicle inner side door panel 13 of the slide door 1 by a base bracket 91. A pair of guide pulleys 92 and 93 are rotatably supported on the base bracket 91 via pins 92a and 93a. The pair of guide pulleys 92 and 93 are arranged in parallel in the same plane along the vehicle front-rear direction (left-right direction in FIG. 5). Therefore, the thickness of the vehicle inside / outside direction (thickness direction of the slide door 1) is thin. As a result, regarding the arrangement of the intermediate pulley mechanism 9 in the slide door 1, the restriction of the arrangement position due to the thickness of the slide door 1 is reduced. The guide pulley 92 is provided with a wire 71 and guides the other end of the wire 71 from the output drum 61 to the movable pulley mechanism 8. A wire 72 is routed on the guide pulley 93 and guides the other end of the wire 72 from the output drum 61 to the movable pulley mechanism 8.
[0020]
As shown in FIG. 4, the movable pulley mechanism 8 has an upper pulley cover 81 and a lower pulley cover 82, and is formed in the opening 83 formed in the upper pulley cover 81 and the middle step portion 51 f of the guide roller unit 5. It is fixed to the guide roller unit 5 via a screw (not shown) that is integrally inserted into the opening 51r. As shown in FIGS. 3 and 4, a part of the movable pulley mechanism 8 is accommodated in the opening 51 k of the guide roller unit 5. As a result, the guide roller unit 5 and the movable pulley mechanism 8 are configured so that their thicknesses overlap in the vicinity of the opening 51k. Therefore, the thickness of the member combining the guide roller unit 5 and the movable pulley mechanism 8 in the vicinity of the opening 51k (shown in FIG. 3) is reduced. On the other hand, the guide cover 24 extends from the side body 2 above the vicinity of the opening 51k. As described above, the distance between the lower end portion of the guide cover 24 and the lower edge portion of the concave portion 22 of the side body 2 is about 10 mm. Therefore, when the side body 2 is viewed from the outside of the vehicle, the concave portion 22 is hardly exposed, and the appearance of the side body 2 is good.
[0021]
As shown in FIG. 3, between the upper pulley cover 81 and the lower pulley cover 82 of the movable pulley mechanism 8, a pair of guide pulleys 84 and 85 (pulleys) are connected to the upper and lower pulley covers 81 and 82 by pins 84a and 85a. On the other hand, it is supported rotatably. The pin 84 a is positioned coaxially with the pin 12, and the rotation center shaft 84 a of the guide pulley 84 is coaxial with the swing center shaft 12 of the guide roller unit 5. Further, the guide pulley 85 is substantially accommodated in the opening 51k. A part of the outer periphery that guides the wires 71 and 72 is located in the vicinity of the wire guide rail 32 inside the recess 22. As shown in FIG. 2, the other ends of the wires 71 and 72 are crossed so as to be guided on both sides of the guide pulleys 84 and 85 and guided to the guide pulleys 84 and 85. Thus, the wires 71 and 72 are routed from the intermediate pulley into the center guide rail 3. A pulley protection member 86 having a substantially stepped cross section is disposed between the upper pulley cover 81 and the lower pulley cover 82. The pulley protection member 86 includes a plate-like member 86b sandwiched between the upper pulley cover 81 and the guide pulley 85, and a plate-like member that is bent and extends from the plate-like member 86b and sandwiched between the guide pulley 84 and the lower pulley cover 82. A member 86c is provided. Furthermore, the pulley protection member 86 has four claw portions 86 a that oppose the wires 71 and 72 arranged in the guide pulleys 84 and 85. The tip of the claw portion 86a is located in the vicinity of the groove formed in the guide pulleys 84 and 85, and scrapes off ice or the like adhering to the groove. Therefore, the guide pulleys 84 and 85 guide the wires 71 and 72 smoothly.
[0022]
Next, the operation will be described.
