[Explanation of operation]

When the sliding door 3 in the door opening state [act of the automatic door closing] closed lightly slide manually, first, the terminal 1 terminal 124 及 beauty pin 126 of the body 1 of the battery-side
29, whereby the controller 1 on the vehicle body 1 side
28 actuates an internal timer T1, power cord 1 to the controller 120 及 beauty locking motor 90
It supplies the necessary power through the 23 及 beauty power cord 125. The sliding door 3 is further closed by inertia and locked
When the latch 13 of the device 8 engages with the striker 10 of the vehicle body 1 and rotates to reach a half-latch state in which the ratchet 14 is engaged with the half-latch step 29 of the latch 13 as shown in FIG. The contact 30 is pressed via the switch arm 28 of the switch body 26 by the pressing piece 27 of the latch arm 25 connected to the latch 13 to turn on the switch body 26.

When the switch body 26 is turned on, the controller 120 regards the state as a half-latch state, activates the internal timer T2 and energizes the motor 40 to rotate the drive gear 97, thereby turning the rotating member 96 in FIG. ,
Rotate counterclockwise. Then, the pin 119 of the moving rod 115 is
Are the engagement groove 102 of the rotating member 96 and the wire rotating arm 1
Since it engages with the long hole 107 of the wire 04, the wire rotating arm 104 also rotates in conjunction with it to wind up the wire 36, and the rotating lever 33 is rotated clockwise in FIG. Thus, since the rotating lever 33 is fixed to the rotating shaft 32 and the interlocking lever 41 is fixed to the rotating shaft 32, the interlocking lever 41 rotates counterclockwise in FIG.
Is moved while being guided by the engagement between the guide groove 47 and the guide pin 45. The roller 46 of the moving pressing body 42 comes into contact with the engagement piece 48 of the latch 13 at the half-latch position, and forcibly rotates the latch 13 clockwise in FIG. 4 to the full latch position in FIG. However, since the contact 30 is still pressed at the full latch position in FIG. 9, the motor 40 continues to be energized, and when the motor is excessively rotated beyond the full latch position as shown in FIG. 10, the contact 30 of the switch body 26 is opened and turned off. Becomes

When the switch body 26 is turned off, the door-side controller 120 determines that the latch 13 has rotated to the excessive rotation position, thereby causing the motor 40 to rotate in the reverse direction. Then, the rotating lever 33 rotates counterclockwise in FIG. 5 by the elastic force of the spring 39 and winds up the wire 36, the pressing body 42 also returns to the position of FIG. 4, and the latch 13 returns to the full latch position by the elastic force of the spring 24. Then, the ratchet 14 is engaged with the full latch step 31 of the latch 13, and the door is closed. When the switch 40 is turned off and the motor 40 is rotated in the reverse direction, when the arc groove 99 of the rotating member 96 comes into contact with the protrusion 100 of the base frame 58 to be in a mechanical lock state, the detector 130 detects an overcurrent caused thereby. Power supply is stopped.

[0029]

Next, the manual closing will be described. When the sliding door 3 in the opened state is manually slid and strongly closed, as is well known, the locking device 8 is closed.
Latch 13 engages with the striker 10 of the vehicle body 1 and rotates to the full latch position, and the full latch step 3 of the latch 13
1, the ratchet 14 is engaged, and the door is closed. In this operation, the rotation of the latch 13 causes the switch body 26 to turn ON / OFF as described in the automatic closing operation.
However, when the door is closed so strongly that the latch 13 rotates excessively , even if the motor 40 rotates forward by turning on the switch 26, the switch 26
Is turned off, whereby the motor 40 immediately reverses and returns. Further, when the latch 13 is closed with the strength to become the full latch, the excessive rotation of the latch 13 cannot be detected, so that the motor 40 performs the same operation as the automatic closing, and returns to the original state after the latch 13 is excessively rotated. Become.

[0030]

[Opening action] When opening the closed sliding door 3,
Outer open handle 5 or by operating the inner open handle 65, the rod 63 or 12 to open lever 61 through the rod 66 is rotated counterclockwise. Then, since the pin 89 of the moving rod 86 is engaged with the engagement groove 70 of the open lever 61 and the long hole 76 of the transmission lever 74, the transmission lever 74 also rotates in conjunction with the open lever 61, and the rod 78 5 through the second ratchet
The arm 52 is rotated. The rotated second ratchet
One end 55 of the arm 52 comes into contact with the other end 56 of the first ratchet arm 49 to rotate the first ratchet arm 49 and rotate the ratchet 14 connected to the first ratchet arm 49 by the connecting pin 51 to thereby make the ratchet 14 Is released from the latch 13 and the door is opened.

[0031]

[Locking action lock by the key cylinder 6 or inside lock operating member 7 or locking motor 90 lever 8
0 is rotated counterclockwise in FIG.
When the pin 89 of the open lever 61 faces the idling groove 71 of the open lever 61, the lock state is established. In this state, even if the door opening operation is performed, the pin 89 of the moving rod 86 only moves in the idle vibration groove 71 of the open lever 61, so that the rotation of the open lever 61 is not transmitted to the transmission lever 74. Can't open.

[0032]

[Manual safety mechanism During the operation of the automatic door closing, when I sandwich the finger or the like to the sliding door 3, immediately, the outer open handle 5 or inner open handle 65
To rotate the open lever 61. Then
Rotates clockwise intermediate lever 108 which is connected directly by a pin 113 to the open lever 61 about the shaft 109, the intermediate
The shaft is fixed to the tip 114 of the lever 108, and the shaft
Of the shaft 117 is the rotating member 96 and the wire rotating arm.
The moving rod 11 whose axis coincides with the axis 95 of the axis stop 104
The fifth pin 119 slides from the engagement groove 102 of the notch groove 101 to the idle vibration groove 103 and moves. Thereby, the pin 11
The connection state between the rotating member 96 and the wire rotating arm 104 connected via 9 is released, and thereafter, the power of the motor 40 is not transmitted to the rotating lever 33 side, and the forced closing is released. Further, the outer open handle 5 or the inner open handle 65, since rotating the open lever 61, the door opening operation is also performed at the same time as the door opening operation. When the sliding door 3 is locked and closed, and a finger is pinched, the rotation of the open lever 61 is not transmitted to the transmission lever 74, so that the door cannot be opened, but the forced closing is immediately stopped. , Serious accidents can be prevented.

When the sliding door 3 is closed,
Although the latch 13 engaged with the striker 10 has once rotated to the half-latch position, the ratchet 14 cannot engage with the half-latch step 29 of the latch 13, and the resilient force of the spring 24 moves the latch 13 to the open position. Returning, the engagement with the striker 10 may be released.
Is a mechanism that rotates forward when the switch body 26 is turned on and reversely rotates when the switch body 26 is turned off, so that the forward rotation of the motor 40 is only instantaneous, and the latch 13 not engaged with the striker 10 is not rotated to the full latch position.

The detection of overcurrent by the detector 130 has another effect. That is, as described above, when an overcurrent is detected while the motor 40 is rotating in the reverse direction, the motor 40 is regarded as having ended the normal reverse rotation operation, and the motor 40 is stopped. When detected,
It is considered that the switch body 26 or the like has failed, the motor 40 is immediately reversed, and if an overcurrent is detected again, the motor 40 is stopped.
