DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a power supply side connector provided on a vehicle body side and connected to a battery of the vehicle body, a door which opens and closes by sliding the vehicle body forward and backward, and closing the door to a predetermined position. A power- receiving- side connector that contacts the power-supply-side connector, an automatic door-closing controller that is connected to the power-receiving-side connector and receives power supply by contacting the two connectors, and a latch that engages with a striker fixed to the vehicle body side; An automatic door closing motor that rotates forward and reverse under the control of the controller, and is provided between the motor and the latch.When the motor rotates forward, the latch is displaced from an initial position toward an operation end position to shift the latch at a half latch position. An automatic door closing device provided with a rotating member for forcibly rotating in a full latch direction, wherein the rotating member is a manual switch.
A structure in which the structure is reversed by turning on the switch is described in Japanese Utility Model Laid-Open Publication No. 3-76982 and many other publications and is well known.

[0003]

Since the battery power on the vehicle body side cannot be constantly supplied to the controller in the sliding door due to the structure of the door, as described above, when the door is closed to a predetermined position, the controller is closed. It is configured to be supplied with power through connectors that contact each other. Therefore, when the door is opened, the connectors are separated from each other, and from that moment the controller and the motor enter a power-off state. what if,
If the door is opened while the power transmission mechanism is being displaced by the motor, the power is cut off and the motor stops, so the power transmission mechanism stops at an intermediate position from the initial position to the operation end position. . As described above, when the power transmission mechanism stops at the middle position, when the power is again supplied by the closing door and the motor rotates, the power transmission mechanism resumes the movement from the middle position, but the power transmission mechanism stops moving from the middle position. When moved, the latch could not be engaged and could not be rotated. Therefore, in the present invention, when performing automatic door closing, the motor is once rotated reversely to return the power transmission mechanism to the initial position, and then the motor is normally rotated. In addition, the conventional publicly known utility system 3-7
Japanese Patent No. 6982 discloses a technique in which the motor is reversed after power is turned on. However, the method of reversing the motor is a structure in which a user manually turns on an operation switch, and This is provided separately from the continuous sequence control for closing the door. For this reason, it is a very inconvenient and unrealistic technique.

As shown in FIG. 3, the guide groove 47 has a right half formed in an arc groove 47A centered on the shaft hole 18 and a left half formed in a retreat groove 47B extending in a direction away from the shaft hole 18. It is formed.

An engaging piece 48 is formed on the latch 13. When the latch 13 rotates to the half-latch position, the engagement piece 48 overlaps with the left end of the arc groove 47A,
When the latch 13 rotates to the full latch position, it is configured to overlap with the right end of the arc groove 47A. When the wire 40 is wound by the motor 40 when the latch 13 is at the half-latch position, the rotation lever 3
3 and the interlocking lever 41 rotate, the pressing body 42 slides rightward from the position shown in FIG. 4 along the guide groove 47, and the roller 46 of the pressing body 42
And the latch 13 is forcibly rotated in the full latch direction.

As shown in FIG. 5, a ratchet arm 49 rotatably supported by the ratchet shaft 16 is provided below the body 11. The ratchet arm 49 and the ratchet 14 are connected to each other by a connection pin 51 that passes through a hole 50 formed in the body 11.

Is indirectly connected to the open handle 5 through
When the lever 52 is rotated by the operation of the handle 5, one end 55 thereof is engaged with the other end 56 of the ratchet arm 49 to rotate the ratchet arm 49 clockwise, thereby releasing the ratchet 14 from the latch 13.

Next, the operation mechanism 9 will be described with reference to FIG.
This will be described with reference to FIGS. The motor 40 and its speed reduction portion 59 are mounted on the base frame 58 of the operation mechanism 9.
Has been fixed. As shown in FIG.
A shaft hole 60a is formed on the left side of 8, and the shaft 60 is inserted through the shaft hole 60a as shown in FIG. Note that the shaft 60 is
In FIGS. 12 and 13, it is shown overlapping with the shaft 85. An open lever 61 (FIG. 15) is rotatably fixed to the shaft 60. The open lever 61 has three legs 62, 68, 112, and the first leg 62 has an arc-shaped hole 64 into which a rod 63 reaching the outer handle 5 of the door 3 is engaged. Inner handle 6

The L-shaped groove 69 includes an engaging groove 70 extending in the radial direction with respect to the shaft 60, and an idle vibration groove 71 bent at a substantially right angle from the tip of the engaging groove 70. The third leg 112 has a pin 1
13 are provided. The open lever 61 is urged in the clockwise direction in FIG. 12 by a spring 72 and stops against the protrusion 73 of the base frame 58.

A substantially L-shaped transmission lever 74 is provided on the shaft 60.
(FIG. 16) is rotatably supported. The first arm 75 of the transmission lever 74 has the engagement groove 7 of the open lever 61.
A long hole 76 corresponding to 0 is formed. The end of the rod 78 reaching the intermediate lever 52 is locked to the second arm 77 of the transmission lever 74 (see FIG. 5). Transmission lever 74
12 is urged in the clockwise direction in FIG. 12 by a spring 79, and comes into contact with the projection 73 of the base frame 58 and stops.

A lock lever 80 (FIG. 18) for switching the lock body 8 between a locked state and an unlocked state is rotatably fixed to the base frame 58 by a shaft 81. A rod 82 reaching the key cylinder 6 and a rod 83 reaching the inside lock operation member 7 are connected to the lock lever 80. A right end 87 of a moving rod 86 is rotatably fixed to an arm 84 of the lock lever 80 by a shaft 85. A pin 89 is attached to the left end 88 of the moving rod 86, and the pin 89 is engaged with both the long hole 76 of the transmission lever 74 and the L-shaped groove 69 of the open lever 61.

The lock lever 80 shown in FIGS. 12 and 13 is in the unlocked position. In this position, the pin 89 is engaged with both the engagement groove 70 of the open lever 61 and the long hole 76 of the transmission lever 74. Because it is engaged with
The open lever 61 and the transmission lever 74 are connected. Therefore, when the open lever 61 is rotated counterclockwise by the outer handle 5 or the inner handle 65 in the state of FIG. 13, the transmission lever 74 also rotates counterclockwise to rotate the intermediate lever 52 of FIG. As a result, the ratchet arm 49 can be rotated clockwise to release the ratchet 14 from the latch 13. When the lock lever 80 is rotated counterclockwise from the position shown in FIG. In the locked position,
The pin 89 moves to the tip of the engagement groove 70, and the idle vibration groove 71
It is a position facing. Therefore, in the locked state, even if the open lever 61 is rotated counterclockwise, the pin 89 cannot be moved, and the transmission lever 74 does not rotate, so that the door cannot be opened.

A motor 90 for switching the lock lever 80 between a locked position and an unlocked position is fixed to the base frame 58. A lever 92 is fixed to the output shaft 91 of the motor 90, and a projection 93 at the tip of the lever 92 is engaged with the fork 94 of the lock lever 80.

A shaft hole 95a is formed near the center of the base frame 58, and a shaft 95 is inserted through the shaft hole 95a as shown in FIG. Note that the shaft 95 is shown overlapping with the shaft 117 in FIG. A rotating member 96 (FIG. 21) is rotatably fixed to the shaft 95. A gear portion 98 is formed on the outer periphery of the rotating member 96 so as to mesh with a drive gear 97 fixed to the output shaft of the speed reducer 59. The base frame 58 has an arc groove 9 centered on the shaft hole 95a.
9 is formed, and the projection 100 formed integrally with the rotating member 96 is engaged with the arc groove 99. The rotating member 96 is shown in FIG.
Is the initial position, and when the motor 40 rotates forward, it rotates in the direction of arrow B from this position. Rotating member 96
Has an engagement groove 10 extending radially with respect to the shaft 95.
Form one. One side wall 102 of both side walls of the engagement groove 101 is formed relatively long, and the other side wall forms an idle passage 103.

A wire arm 104 (FIG. 22) is rotatably fixed to the shaft 95, and one end 105 of the wire arm 104 is engaged with an end of the wire 36 reaching the lock body 8. An elongated hole 107 corresponding to the engaging groove 101 of the rotating member 96 is formed in the other end 106 of the arm 104. An intermediate lever 108 is attached to the base frame 58 by a shaft 109.
Is rotatably fixed to the shaft. The intermediate lever 108 is a spring 111
12, the one end 110 is in contact with the pin 113 of the open lever 61. At the other end 114 of the intermediate lever 108, a base end 116 of a moving rod 115 is rotatably fixed by a shaft 117. The notch 10 is provided at the tip 118 of the moving rod 115.
A pin 119 is formed which engages both the slot 1 and the slot 107.

As shown in FIG.
Is in contact with the projection 73 by the elasticity of the spring 72, one end 110 of the intermediate lever 108 contacts the pin 113 of the open lever 61, and the other end 114 of the intermediate lever 108.
Axis 117 coincides with the axis of the axis 95. In this state, the pin 119 of the moving rod 115 is
01 and the long hole 107, the rotating member 96 and the wire arm 104 are integrally connected. Therefore, when the driving gear 97 is rotated by the motor 40 to rotate the rotating member 96 in the direction of the arrow B, the wire arm 104 also rotates in the direction of the arrow B, whereby the wire 36 is wound up. Rotating lever 33
Rotates clockwise against the spring 24.

However, when the open lever 61 is rotated counterclockwise in FIG. 12 by the handle 5 or the handle 65, the intermediate lever 108 is pressed by the pin 113 and rotates clockwise about the shaft 109.
The reference numeral 19 moves in the direction away from the shaft 95 in the engagement groove 101 and is displaced to a position facing the idle vibration passage 103. In this state, the connection between the rotating member 96 and the wire arm 104 is disconnected. Therefore, when the handle 5 or the handle 65 is operated while the motor 40 is operating, the rotating member 96 is rotated in the direction of arrow B by the motor 40 as shown in FIG. Since the force in the direction of arrow A is applied via the wire 36 by the elasticity of the attached spring 39, the wire arm 10
4 returns to the initial position. The mechanism that cuts off the power transmission is the manual safety mechanism X.

The automatic door closing controller 120 is mounted on the base frame 58. Controller 12
0 is a cable 121 reaching the switch 26, a cable 122 reaching the motor 40,
4 and a cable 131 (FIG. 12) reaching the motor 90.

The connector 124 and the connector 1
The structure of 29 will be described with reference to FIGS. The connector 124 is provided with a plus terminal 134a, a ground terminal 134b, and a signal terminal 134c, and the terminals 134a to 134c are respectively connected to three cords 123a to 123c of the cable 123 reaching the controller 120. The connector 124 further includes a cable 12 leading to the motor 90 for switching the lock lever 80.
5, a pair of terminals 136a and 136b are provided. The five terminals of the connector 124 are each elastically projected outward by a spring.

The connector 12 provided on the vehicle body 1
9 has three terminals 1 corresponding to the terminals 134a to 134c.
33a to 33c and a pair of terminals 135a and 135b corresponding to the terminals 136a and 136b are provided. The terminals 133a-
c are elastically protruded outward by springs, and are connected to the power supply controller 128 of the vehicle body 1 by cords 126a to 126c of a cable 126, respectively. The terminals 135 a and 135 b are connected to the power supply controller 128 by a cable 132. The terminals 133a to 133c of the connector 129 and the connector 124
The terminals 134a to 134c contact each other when the door 3 is closed to a predetermined position. The contact timing may be any time before the latch 13 is brought into the half-latch position by engagement with the striker 10, and no strict setting is required. For example, when the striker 10 enters the passage 17, the terminals are brought into contact with each other.

The power supply controller 128 applies a voltage for contact detection to the signal terminal 133c via the cord 126c, and connects the terminals 133a-c to the terminals 134a.
To c contact each other, the signal terminal 133c on the power supply side
, A current flows to the automatic closing controller 120 via the signal terminal 134c on the power receiving side, and the current flowing to the controller 120 returns to the ground terminal 133b on the power supply side via the ground terminal 134b on the power receiving side. That is,
In the open state, no current flows through the signal terminal 133c of the vehicle body 1 because it is an open end, but when the terminal groups come into contact with each other, an electric loop is formed so that the current flows. When the current flows, the power supply controller 128 supplies the power of the battery 127 to the plus terminal 133a via the cord 126a, assuming that the connectors are in contact with each other.
As a result, the power required for rotating the motor 40 is supplied to the automatic door closing controller 120.

The automatic door closing controller 120 is provided with a detector 130 for detecting the rotation state of the motor 40. In the present application, the detector 130 uses an ammeter to monitor the current flowing through the motor, thereby detecting rotation and stop of the motor 40. However, the configuration of the detector 130 is not limited to this, and various types can be used.

[0028]

[Action of automatic closing] In the open state, the connector 1 of the door 3
Since the connector 24 and the connector 129 of the vehicle body 1 are not in contact with each other, power is not supplied to the automatic door closing controller 120 of the door 3 and the switch 26 is off because the latch 13 is in the open position. (Actually, the switch 26 cannot be operated because the controller 120 is not energized.) The power supply controller 128 of the vehicle body 1
A voltage for contact detection is applied to the signal terminal 133c via the terminal c. When the sliding door 3 is manually slid in the closing direction, the terminals 134a, b, c of the connector 124 and the terminals 133a, b, c of the connector 129 come into contact with each other before the latch 13 reaches the half-latch position. Then
By the voltage applied to the signal terminal 133c, the signal terminal 1
A current flows from 33c to the automatic closing controller 120 via the signal terminal 134c, and this current returns to the ground terminal 133b of the vehicle body 1 via the ground terminal 134b of the door 3. Thus, when the current flows, the power supply controller 12
8 is considered as contact between the connectors, and the battery 127
Is supplied to the automatic closing controller 120 via the plus terminals 133a and 134a (step 3).

The controller 120 that has been supplied with power
Confirms the position of the latch 13 based on the signal from the switch 26 and waits until the latch 13 enters the half-latched state (step 4). When the door 3 further moves due to inertia and the latch 13 rotates to the half-latch position shown in FIG. 8, the bent portion 27 of the latch arm 25 connected to the latch 13 by the stepped pin 21 causes the switch 2 to move.
By rotating the switch arm 28 of No. 6, the contact 30 is pressed, and the switch 26 is turned on. When the switch 26 is turned on, the controller 120 supplies reverse rotation electricity to the motor 40 (step 5), and rotates the rotating member 96 in the direction indicated by the arrow B in FIG. Make sure to put it back. When the rotating member 96 returns to the initial position, the protrusion 100 of the rotating member 96
8 comes into contact with the end of the circular arc groove 99 to enter the mechanical lock state, and the motor 40 stops. Then, since the current flowing through the motor 40 changes, this is detected by the detector 130 (step 6).

When the rotating member 96 returns to the initial position, the controller 120 supplies a current for normal rotation to the motor 40, thereby rotating the rotating member 96 in the direction of arrow B (step 7). Then, the pin 119 of the moving rod 115 is
Are the engagement groove 101 of the rotating member 96 and the wire arm 104
5, the wire arm 104 also rotates in the direction of arrow B to wind up the wire 36, and the rotating lever 33 is rotated clockwise in FIG. When the rotation lever 33 rotates, the interlocking lever 41 rotates counterclockwise in FIG. 4 via the rotation shaft 32, and the pressing body 42 moves to the right while being guided by the groove 47. Then, the roller 46 of the pressing body 42 comes into contact with the engaging piece 48 of the latch 13 at the half-latch position, and forcibly rotates the latch 13 clockwise to displace to the full-latch position. However, since the switch 26 is still ON at the full latch position, the motor 40 continues to rotate, and the latch 13 rotates excessively beyond the full latch position as shown in FIG. Then switch 2
6 is turned off (step 8).

When the switch 26 is turned off, the controller 120 considers that the latch 13 has rotated to the surplus rotation position, thereby causing the motor 40 to rotate in the reverse direction (step 9). Then, the rotating member 96 and the wire arm 1
Since 04 rotates in the direction indicated by the arrow B, the wire 36 is loosened, the rotating lever 33 rotates counterclockwise in FIG. 5 by the elastic force of the spring 39, and the pressing body 42 also returns. The excessively rotated latch 13 is returned to the full latch position by the elasticity of the spring 24, and the ratchet 1
4 engage. By the reverse rotation of the motor 40, the rotating member 96 is rotated.
Is returned to the initial position, the projection 100 of the rotating member 96 comes into contact with the end of the circular arc groove 99 of the base frame 58 to be in the mechanical lock state, and the motor 40 stops. Then, the current flowing through the motor 40 changes.
(Step 10), whereby the controller 120 stops supplying power to the motor 40 (Step 11) and sends an end signal to the power supply controller 128 of the vehicle body 1 (Step 12). Upon receiving the end signal, the power supply controller 128 stops supplying power to the plus terminal 133a (step 13).

[0032]

[Safety mechanism] When the latch 13 is moving from the half latch position to the full latch position by the power of the motor 40, the switch 26 is kept ON (step 8). 130 to motor 40
The rotation status of the motor 4 is monitored (step 14).
When the rotation stop of 0 is detected, it is considered that an abnormality has occurred, and the motor 40 is immediately reversed (step 9). In the abnormal situation, when the door 40 is closed, the foreign matter is caught and the motor 40 stops, or the switch 26 breaks down.
This corresponds to a case where the excessive rotation of the latch 13 cannot be detected. Further, when the hand is caught in the door 3 during the automatic door closing operation, even if the hand is left as it is, the detector 130 detects the abnormality of the motor 40 as described above, and the motor 40 rotates reversely. . However, when the finger is pinched, before the automatic safety control by the controller 120 operates,
It is necessary to actively activate the manual safety mechanism. In the present application, when the hand is sandwiched between the doors 3, the outer handle 5 or the inner handle 65 is quickly operated to rotate the open lever 61 counterclockwise in FIG. Then, the intermediate lever 1 kicked by the pin 113 of the open lever 61
Reference numeral 08 rotates clockwise about the shaft 109, and the pin 119 of the moving rod 115 separates from the engagement groove 101 of the rotating member 96 and moves to a position facing the air vibration passage 103. As a result, the connection between the rotating member 96 and the wire arm 104 via the pin 119 is released, and thereafter, the power of the motor 40 is not transmitted to the wire arm 104, and the automatic door closing by the power is interrupted. . In this way, when the connection between the rotating member 96 and the wire arm 104 is released, the load on the motor 40 sharply decreases, so that the current value or the rotation speed changes. This change is detected by the detector 130.
Is detected (step 15), the controller 120 regards the operation of the manual safety mechanism and checks the position of the lock lever 80 (step 16). When the lock lever 80 is at the unlock position, the controller 40 immediately Is reversed (step 9).

Next, the reason for confirming the position of the lock lever 80 in step 16 will be described. When the lock lever 80 is in the unlocked position and the manual safety mechanism is operated as described above, the open lever 61 rotates, whereby the transmission lever 74 also rotates via the pin 89 and the rod 78 via the rod 78. The intermediate lever 52 shown in FIG. 5 is rotated. 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 released from the latch 13. Therefore, when the manual safety mechanism is operated in the unlocked state, the automatic closing by the motor 40 is interrupted and the door 3 is opened. However, if the lock lever 80 is in the lock position when the manual safety mechanism is operated, the ratchet 14 cannot be disengaged from the latch 13 because the transmission lever 74 does not rotate even if the open lever 61 rotates. For this reason, even if the latch 13 released from the motor 40 attempts to reversely rotate toward the open position due to the elasticity of the spring 24, the ratchet 14 is
, The half-latch state is not released and the door cannot be opened. For this reason, in this application, when the manual safety mechanism operates, the position of the lock lever 80 is checked, and when the lock lever 80 is in the lock position, the controller 120 energizes the motor 90 and unlocks the lock lever 80. Switch to position (Step 1
7). Therefore, when the manual safety mechanism is operated in the locked state, the automatic door closing by the motor 40 is interrupted, and the lock lever 80 switches to the unlock position. Then, when the open lever 61 is rotated again by operating the handle 5 or 65, the door 3 can be opened immediately because the lock lever 80 has already been switched to the unlocked state. That is, in any situation, the door 3 can be opened by operating the handle 5 or 65 twice.

[0034]

[Reopening action after the manual safety mechanism is activated] As described above, when the manual safety mechanism is operated by the outer handle or the inner handle during the automatic closing by the motor 40, the forced closing is interrupted and the door 3 is opened. Will be. However, when the door 3 is opened, the connector 129 on the vehicle body 1 side is opened.
And the connector 124 on the door 3 side is separated, so that power supply to the controller 120 is stopped from this moment. As a result, the motor 40 enters the no-power state, and the rotating member 96 stops at an intermediate position. Also, the wire arm 104
When the pin 119 moves to the idle path 103 of the rotating member 96 by the operation of the manual safety mechanism, the pin 119 is pulled in the direction of the arrow A via the wire 36 by the elastic force of the spring 39 attached to the rotating lever 33, and returns to the initial position. I do. FIG. 26 shows this state. As is clear from FIG. 26, when the rotating member 96 stops at an intermediate position, the pin 119 is stopped.
Is released from the engaging groove 101 and faces the idle vibration passage 103, so that it cannot return to the engaging groove 101. Therefore, even if the motor 40 is energized again and the rotating member 96 is rotated in the direction of arrow B, the rotating member 96 cannot move the pin 119, so that the automatic door cannot be closed. Therefore, in the present invention, as already described in the operation of the automatic closing operation, the motor 40 is reversed in step 5 to return the rotating member 96 to the initial position once. Thus, when the rotating member 96 is returned to the initial position,
The pin 119 engaged with the idle vibration passage 103 is
1 into the engagement groove 101 by the elastic force of
The connection state between the wire arm 6 and the wire arm 104 is restored, and the state is returned to a state where automatic closing is possible.

[0035]

Next, the operation of the manual closing will be described. When the sliding door 3 in the opened state is manually slid strongly, the latch 13 of the lock body 8 is moved by the strong inertia of the door 3 as is well known. Engages with the striker 10 of the vehicle body 1 and rotates all at once to the full latch position, the ratchet 14 engages with the full step portion 31 of the latch 13, and the closing of the door is completed regardless of the power of the motor 40. However, even when the door is manually closed, the switch 26
Is switched at any time, and the controller 120 also controls the motor 40 in response to this. However, in the manual door closing operation, the switch 26 is changed instantaneously, so that the motor 40 The reverse operation is performed as the end operation.

[0036]

[Other Actions] When the sliding door 3 is closed, the ratchet 1 is rotated in spite of the fact that the latch 13 engaged with the striker 10 has once rotated to the half-latch position.
The latch 13 may return to the open position due to the elasticity of the spring 24 because the latch 4 cannot engage with the half step portion 29 of the latch 13. Even in such a case, in the present application, the motor 40 rotates forward only when the switch 26 is ON, so that the latch 13 not engaged with the striker 10 is not rotated to the full latch position.
