DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic closing lock device for a vehicle door.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open Publication No. Hei 2-200981 discloses that when a door is manually closed to a half-latch state, a motor is thereafter energized and the power automatically and forcibly causes the door to be fully latched. Describes an auto-close type locking device for completely closing the door. In this known example, since the door is forcibly closed by a motor, if a finger or a foreign object is caught, it is necessary to urgently stop the forcible door by the motor, and a safety mechanism is provided. The safety mechanism includes a power transmission mechanism that forcibly closes the door by a motor, and includes an engagement / disengagement mechanism that moves a moving rod, and an intermediate lever that rotates by rotation of an open lever when the door opening handle is opened. At the other end of the moving rod. The known example has a configuration in which one end of an intermediate lever is engaged with an end of an open lever, and the other end of the intermediate lever hits the head of a moving rod to perform a pressing movement, and the moving rod is driven by a motor. It also has a rotating structure. Therefore, the head of the moving rod moving by the motor is hit, so that the structure becomes complicated, the movement locus of the moving rod moved by the motor, and the rotation of the other end of the intermediate lever hitting the head of the moving rod. If the motor rotates after the intermediate lever is rotated by the open lever, there is also a problem that the moving rod collides with the intermediate lever because the relationship is intersected with the trajectory (this is not true otherwise). For this reason, the present applicant has previously filed an application (Japanese Patent Application No. 5-20693) which has solved this point. The configuration of the prior application includes a latch that engages with the striker to rotate, a ratchet that engages with the latch to prevent the latch from rotating in the reverse direction, and an auto-close that rotates when energized when the latch is in the half-latch position. Motor, a rotating member rotated by the motor, a rotating arm rotated by the rotation of the rotating member, an open lever for releasing the ratchet from the latch, and an open lever when the open lever is opened. An intermediate lever that is pivoted by the intermediate lever, and a moving rod that is pivotally supported by the other end of the intermediate lever and moves together with the rotation of the intermediate lever to disengage the engagement between the rotating member and the rotating arm. It is the structure which consists of.

[0003]

The above-mentioned prior art solves the problem of the prior art. However, if the motor breaks down when the safety mechanism is operated by opening the opening lever, the opening operation performed by the opening operation is performed. There is a problem in that the lever does not return from the position where the door is opened, and the door cannot be closed manually. That is, when the safety mechanism is operated by rotating the open lever while the motor is operating, the moving rod is pushed out and disengages from the engagement groove of the rotating member on the motor side, and the outer peripheral surface of the rotating member (idle groove). Engage with. In this state, if the motor malfunctions, the rotating member rotated by the motor cannot rotate at that position and stops, so that the moving rod remains engaged with the outer peripheral surface of the rotating member. For this reason, since the moving rod is held at the position pushed by the open lever, the open lever is also held at the rotated (extruded) position. Then, since the open lever is always in the operating state, it interferes with the normal opening / closing door. The present invention has solved the above-mentioned problem by changing the interlocking structure between the open lever and the intermediate lever.

[0004]

After the terminals have come into contact with each other, the sliding door 3 is further closed by inertia, and the latch 13 of the lock body 8 is engaged with the striker 10 of the vehicle body 1 and rotates.
When the ratchet 14 is engaged with the half engagement step 29 of the latch 13 as shown in FIG.
The pressing piece 27 of the latch arm 25 connected to the latch 13 by 1 presses the contact 30 via the switch arm 28 of the switch body 26 to turn on the switch body 26. When the switch body 26 is turned on, the controller 120, which has already been supplied with power, regards it as a half-latched state, supplies a current for reverse rotation to the motor 40 for automatic closing, and determines in which position the rotating member 96 is located. However, it is surely returned to the initial position in FIG. The movement of the rotating member 96 at this time is a movement in a direction in which the wire 36 is loosened, so that the movement of the latch 13 is not affected.

The guide pin 45 moves to the right while being guided by the engagement with the guide pin 45. At this time, since the latch 13 is at the half-latch position, the engagement piece 48 is at the left end position of the arc groove 47A, and the roller 46 of the moving pressing body 42 comes into contact with the engagement piece 48 to release the latch 13. Force clockwise rotation to displace to full latch position. However, since the contact 30 is still pressed in the full latch position as shown in FIG. 9, the motor 40 continues to be energized, and when the motor 40 is excessively rotated beyond the full latch position as shown in FIG.
Contact 30 is opened and turned off.

When the switch body 26 is turned off, the auto-close controller 120 regards the latch 13 as having rotated to the excessive rotation position, and thereby causes the motor 40 to rotate in the reverse direction. Then, since the wire 36 is loosened, the rotating lever 33 rotates counterclockwise in FIG. 5 by the resilience of the spring 39 and winds up the wire 36, the pressing body 42 also returns to the position of FIG. The latch 13 is returned to the full latch position by the elastic force, and the ratchet 14 is engaged with the full engagement step 31 of the latch 13 to complete the door closing.

Next, the operation of the manual closing will be described. When the sliding door 3 in the opened state is manually slid and strongly closed, the latch 13 of the lock body 8 is moved to the striker of the vehicle body 1 as is well known. 10 and rotate to the full latch position, and the ratchet 14 engages with the full engagement step 31 of the latch 13 to complete the door closing. In this operation, when the latch 13 rotates, the switch body 26 is turned OFF / ON / O as described in the automatic closing operation.
Although it changes to FF, when the latch 13 is closed so strongly that the latch 13 rotates excessively, the change of the switch body 26 is performed instantaneously, so that the motor 40 performs reverse rotation as an end operation before almost moving. Become. In addition, when the latch 13 is closed with the strength to become the full latch, the surplus 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 surplus rotation of the latch 13. Become.

[Opening action] When opening the closed sliding door 3,
By operating the outer handle 5 or the inner handle 65, the open lever 61 is rotated counterclockwise through the rod 63 or the rod 66 in FIG. 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 The intermediate lever 52 of FIG. One end 55 of the rotated intermediate lever 52 comes into contact with the other end 56 of the ratchet arm 49 to rotate the ratchet arm 49 and connect the connecting pin 51 to the ratchet arm 49.
By rotating the ratchet 14 connected by the above, the ratchet 14 is detached from the latch 13 and the door is opened.

[0033]

[Locking action] The lock lever 80 is rotated counterclockwise in FIG. When it comes, it is locked. 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.

[0034]

[Manual safety mechanism] If a finger or the like is caught in the sliding door 3 during the operation of the automatic closing, the outer handle 5 or the inner handle 65 is operated to rotate the open lever 61 immediately. Then, the intermediate lever 108 in contact with the pin 113 of the open lever 61 rotates clockwise about the shaft 109, and the pin 119 of the movable rod 115 is rotated.
Moves in the engagement groove 101 of the rotating member 96 in a direction away from the shaft 95 and moves into the idling passage 103 on the distal end side of the engagement groove 101. As a result, the connection state between the rotating member 96 and the wire rotating arm 104 via the pin 119 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, since the open lever 61 is rotated by the outer handle 5 or the inner handle 65, the door opening operation is performed at the same time as in the door opening operation. When a finger is caught when the slide door 3 is closed with the lock lever 80 in the lock position, the open lever 61 is operated twice, the safety mechanism X is operated by the first operation, and the lock lever 80 is operated. Is switched to the unlock position, and the door is opened by the second operation. That is, when the open lever 61 is operated while the lock lever 80 is in the lock position, the intermediate lever 108 rotates clockwise, and
The fifth pin 119 moves from the engagement groove 101 to the idle vibration passage 103. Thereby, the rotating member 96 via the pin 119 is
And the connection state of the wire rotating arm 104 is released,
After that, the power of the motor 40 is not transmitted to the rotating lever 33 side, and the forced closing is released. At this stage, since the lock lever 80 is in the lock position, the open lever 61
Cannot be transmitted to the transmission lever 74, so that the door cannot be opened. However, when the communication between the motor 40 and the latch 13 is disconnected by the operation of the safety mechanism X, the current value of the motor 40 sharply decreases.
When 0 detects a sudden decrease in the current value, the safety mechanism X
Has been activated, the controller 120 determines that code 1
The lock motor 90 is operated via 31 to switch the lock lever 80 to the unlock position. Next, when the open lever 61 is operated again, since the lock lever 80 has been switched to the unlock position, the transmission lever 74 also rotates, and the intermediate lever 52 in FIG. One end 55 of the rotated intermediate lever 52 comes into contact with the other end 56 of the ratchet arm 49 to rotate the ratchet arm 49 and connect the connecting pin 5 to the ratchet arm 49.
By rotating the ratchet 14 connected by 1, the ratchet 14 is detached from the latch 13 and the door can be opened. Therefore, according to the present invention, regardless of whether the lock lever 80 is in the locked position or the unlocked position,
By operating, the automatic closing and closing of the door can be performed, and a serious accident can be prevented from occurring.

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-engaging step 29 of the latch 13, and the elastic force of the spring 24 moves the latch 13 to the open position. Back to
Although the engagement with the striker 10 may be released, in such a case as well, in the present invention, the motor 40 is a mechanism that rotates forward by turning on the switch body 26 and reversely rotates by turning off the switch body 26. The forward rotation of 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, if the motor 40 detects an overcurrent during normal rotation,
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.

[0036]

[Door closing action after the safety mechanism is activated]
When the safety mechanism X is operated by opening the outer handle or the inner handle during the forced closing by 0, the intermediate lever 108 is rotated clockwise by the rotation of the open lever 61. To move to the idle vibration passage 103, and thereafter, the power of the motor 40 is not transmitted to the latch 13 side, and the rotating member 96 is idled, and the forced closing is interrupted. Therefore, although the door 3 is opened, when the door 3 is opened, the connector 129 on the vehicle body 1 side and the connector 124 on the door 3 side are separated, and the energization is cut off, so that the motor 40 stops immediately. FIG. 22 shows this state. In FIG. 22, the rotating member 96 rotated by the motor 40 is stopped at a position rotated counterclockwise from the initial position in FIG. 12, and the wire rotating arm 104 is connected to the arrow of the spring 39 via the wire 36. Since the moving rod 115 receives the force in the direction A, it is fully rotated clockwise with the pin 119 of the moving rod 115. Therefore, even if the door 3 is closed again from the state of FIG. 22 and the motor 40 is energized and rotated forward, the wire rotating arm 104 cannot be rotated in the door closing direction.

Therefore, in the present invention, as described in the section of the operation of the automatic door closing, the switch body 26 is closed by the door closing.
At N, the controller 120 firstly sets the motor 40
Is supplied to the rotating member 96 to rotate the rotating member 96 in FIGS.
In step 2, it is rotated clockwise to reliably return to the initial position. As described above, when the rotating member 96 is returned to the initial position, the pin 119 of the moving rod 115 comes to a position facing the engaging groove 101, so that the intermediate lever 108 is rotated by the spring 111, and the pin 119 is moved to the engaging groove 101. And the rotating member 96 and the wire rotating arm 104 are connected.
After this state, a current for normal rotation is supplied to the motor 40. Therefore, the auto-close mechanism operates normally regardless of the position of the motor 40 (rotating member 96).

In the above description, when the door 3 is closed again from the state shown in FIG. 22, the motor 40 moves. However, when the safety mechanism X is operated, the motor 40 may also fail at the same time. . In this way, if even the motor 40 fails, the motor 40 does not rotate even if the door 3 is closed again, so that the rotating member 96 is fixed at that position. Therefore, thereafter, the pin 119 remains engaged with the outer peripheral surface of the rotating member 96 as shown in FIG.
As a result, the intermediate lever 10 connected to the pin 119 side
8 is also fixed at a considerably rotated position. For this reason, when the intermediate lever 108 and the open lever 61 are directly connected, the open lever 61 is also fixed at a considerably rotated position, so that the opening / closing door operation is affected as described at the beginning.

Therefore, according to the present invention, the open lever 61 and the intermediate lever 108 are configured so that the pin 113 and the one end 110 can freely contact and separate from each other. In the event that the intermediate lever 108 cannot be operated, as shown in FIG. In addition, even if it stops at the clockwise position against the elasticity of the spring 111, the open lever 61
Since the can be rotated independently, the operation of the opening and closing door is not affected.
