[0023]
The moving member (35) is slidably mounted on the guide track (5), and has a substantially U-shaped cross section as shown in FIG. 13, and has a base plate (35a) connected to the door (2) side. ) And a first roller (35b) pivotally mounted on a base plate (35a) with a horizontal axis (37) and capable of rolling on a bottom piece (5c) of a guide track (5), as shown in FIG. On both sides of the first roller (35b), it is pivotally mounted on the base plate (35a) with front and rear vertical axes (38), and rolls between the both side pieces (5d) and (5e) below the guide track (5). A possible front and rear second roller (35c), and provided above the first roller (35b) and the second roller (35c) in the guide track (5), and provided with an opening cable (12a) and a closing cable ( 12b) has a connecting portion (36) connected from the front-back direction.
[0024]
The door-opening cable (12a) and the door-closing cable (12b) sent out from the drive pulley of the door drive unit (11) are guided from the indoor side by the rear guide member (30) and pass through the mounting hole (1c). The guide track (5) is guided into the guide track (5) from the rear end.
[0025]
The door opening cable (12a) is guided by the upper first rear pulley (28), extends forward in the guide track (5), and is connected to the connecting portion (36) of the moving member (35). .
[0026]
The door closing cable (12b) is guided by the lower second rear pulley (29), is inserted from the rear end of the guide track (5) into the cable guide groove (5b), and extends forward, and the guide track (5) At the front end of the guide track (5), it is guided backward in a U-turn by the first front pulley (22), extends backward in the guide track (5), and is connected to the connecting portion (36) of the moving member (35). .
[0027]
As shown in FIG. 14, the terminal members (12c) and (12d) fastened to the respective ends of the door-opening cable (12a) and the door-closing cable (12b) face each other, so that the connecting portion ( 36) It is slidably fitted inside. Between each end member (12c) (12d) and the end of the connecting portion (36), the door-opening cable (12a) and the door-closing cable (12b) are urged in a tensioning direction, respectively. Coil springs (43) for absorbing slack are contracted.
[0028]
The moving member (35) is connected to the door (2) via a hinge bracket (39), and the door opening cable (12a) or the closing cable (12b) is rotated by rotation of the motor (13) of the door drive unit (10). ), The guide track (5) is moved forward or backward to move the door (2) in the opening direction or the closing direction.
[0029]
The hinge bracket (39) is connected to a rail-side arm (39a) connected to the base plate (35a) of the moving member (35), and is pivotally connected to the rail-side arm (39a) with the shaft (41). And a door-side arm (39b) coupled to the vehicle body panel (1) and fixed to the recess (1b) of the vehicle body panel (1) through the mounting hole (1c) of the vehicle body panel (1) from the indoor side. After that, the rail side arm (39a) is connected to the base plate (35a) with bolts (40).
[0030]
On the opposing surface of the base plate (35a) and the rail side arm (39a), two concave portions (39c) and two convex portions (35d) for alignment with the moving member (35) of the hinge bracket (39) are formed. Have been.
[0031]
The door moving device (10) is assembled by connecting the door driving unit (11), the guide track (5), and the door driving cable member (12) to each other before being attached to the vehicle.
In this assembled state, the front end of the guide track (5) is inserted into the mounting hole (1c) from the indoor side, and the guide track (5) and the door drive cable member (12) are passed through the outdoor side, and bolts are inserted. With (44), the guide track (5) is fixed to the concave portion (1b) of the vehicle body panel (1), and the door drive part (11) is fixed to the vehicle body panel (1) on the indoor side.
[0032]
After fixing the guide track (5) to the vehicle body panel (1), the hinge bracket (39) is bolted to the base plate (35a) of the moving member (35) slidably provided on the guide track (5). ) To fix.
[0033]
Next, the hinge bracket (39) is connected to the sliding door (2) supported by the upper track (3) fixed to the vehicle body panel (1) and the lower track (4) so as to be openable and closable. ) And the door drive section (11) are connected via a door drive cable member (12).
Therefore, since the large hinge bracket (39) is not attached to the guide track (5), the mounting hole (1c) drilled in the vehicle body panel (1) has only the moving member (36) in the guide track (5). May be as large as the number of holes to be assembled, an extremely small opening amount is sufficient, and the number of perforations may be one.
[0034]
In the fully closed state shown in FIG. 4, the door switch (2a) is disengaged from the striker by the opening operation of the operation switch provided near the driver's seat, and the motor (13) rotates forward while The electromagnetic clutch provided in the reduction unit (14) is excited, the rotational force of the motor (13) is transmitted to the drive pulley, the cable for opening the door (12a) is involved, and the cable for closing the door (12b) is sent out. .
When the door-opening cable (12a) is entangled, the door-opening cable (12a) is pulled in the guide track (5), and the moving member (35) is moved in the door-opening direction. The door is moved in the door opening direction.
[0035]
When the door (2) reaches the position just before the fully open position, the detection rod (32a) of the slider (32) is pushed by the moving member (35) and moves from the protruding position shown in FIG. The switch (34) detects the fully open position of the door (2), cuts off the power supply to the motor (13) and the electromagnetic clutch, and stops the door (2) at the fully open position.
[0036]
In the fully open state shown in FIG. 5, when the motor (13) is reversed by closing the operation switch, the electromagnetic clutch is excited, and the torque of the motor (13) is transmitted to the drive pulley. (12b) is involved, and the door opening cable (12a) is sent out.
[0037]
Due to the winding of the door closing cable (12b), the door closing cable (12b) is pulled in the guide track (5) through the guide groove (5b) of the guide track (5). Accordingly, the moving member (35) rolls on the bottom piece (5c) of the guide track (5) and moves in the door opening direction, and the door (2) is forcibly moved in the door closing direction.
Since the guide track (5) is formed integrally with the cable guide groove (5d) to increase the section modulus and improve rigidity, the guide track (5) is affected by the weight of the door (2). Of the moving member (35) can be obtained.
[0038]
When the door (2) reaches the fully closed position, the door lock (2a) is engaged with the striker and is held at the fully closed position, and the motor is operated by a fully closed detection switch (not shown) for detecting the engagement of the door lock. (13) and energization to the electromagnetic clutch are cut off.
[0039]
【The invention's effect】
According to the present invention, the following effects can be obtained.
(a) By integrally forming the track portion for accommodating the movable member in the guide track and the cable guide groove for guiding the cable, the door drive cable member can be routed before the vehicle body is assembled. As a result, the wiring work can be easily performed, and the efficiency and accuracy of connecting the slide door and the door drive cable member can be improved.
[0040]
(b) Since the track section and the cable guide groove are formed integrally with the guide track, the section modulus of the guide track is increased, the rigidity of the entire guide track is increased, and the bottom piece is reinforced to bend due to the weight of the door. , And smooth opening and closing movement of the door can be obtained.
