Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic closing door lock device for a sliding door, and more particularly,
This is a vertical arrangement of the plus side contact terminal and the minus side contact terminal of the connector that supplies power to the lock device.

[0002]

2. Description of the Related Art Conventionally, when a vehicle door is closed to a half-latch state (so-called a half-door), a motor or the like is automatically energized to forcibly rotate the latch, thereby rotating the door to a full-latch position and closing the door. Automatic closing door lock devices are known. Since the lock device is installed in the door, the power cord of the motor is wired from the battery mounted on the vehicle body side, but in the case of a sliding door such as a wagon car, it is structurally different from the battery of the vehicle body. It is difficult to keep the motor in the door connected with one power cord. Therefore, the connector connected to the battery on the vehicle body side and the connector connected to the motor of the door-side lock device are connected when the door is closed so that the motor is energized.

[0003]

In the above-mentioned connector, the connector connected to the battery on the vehicle body side is provided so as to project outward by several cm. This is because we expect the action of energizing as soon as possible just before the half-latch. Therefore, the positive terminal and the negative terminal may be exposed to rainwater, or a metal body such as a driver may come into contact with each other to cause a short circuit.

[0004]

An object of the present invention is to prevent a short circuit of a connection terminal of a connector.

[Operation of automatic door closing] When the sliding door 3 in the open state is manually slid and lightly closed to be close to the half-latch state, the automatic closing terminals 134a, b, c of the connector 124 on the door 3 side and the vehicle body. 1-side connector 1
The 29 auto-close terminals 133a, b, c contact each other, and a weak current flows due to the contact between the terminals 133b, c and the terminals 134b, c.
Is detected, the terminal 133a of the plus side cord 126a
Power supply to the terminal 134a to supply necessary power to the auto-close controller 120. Even after the above terminals are in contact with each other, the sliding door 3 is further closed due to inertia, the latch 13 of the lock body 8 engages with the striker 10 of the vehicle body 1 and rotates, and as shown in FIG. When the ratchet 14 is engaged with the joint portion 29 in the half-latch state, the pressing piece 27 of the latch arm 25 connected to the latch 13 by the stepped pin 21 presses the contact 30 via the switch arm 28 of the switch body 26. Then
The switch body 26 is turned on.

When the switch body 26 is turned on, the controller 120, which has already been supplied with electric power, is considered to be in a half-latch state, and a current for reverse rotation is supplied to the motor 40 for automatic closing, so that the rotating member 96 is operated. Even if it is in the position, it is surely returned to the initial position in FIG. Since the movement of the rotating member 96 at this time is the movement in the direction of loosening the wire 36, it does not affect the movement of the latch 13. When the rotating member 96 returns to the initial position, the protrusion 100 of the rotating member 96
Comes into contact with the end of the arc groove 99 of the base frame 58 to be in a mechanical lock state, so that the detector 130 detects an abnormal current generated by this and supplies a current for forward rotation to the motor 40, thereby rotating. The member 96 is rotated counterclockwise in FIG. Then, the pin 119 of the moving rod 115 is engaged with the engaging groove 101 of the rotating member 96 and the wire rotating arm 10.
Since the wire rotating arm 104 also rotates counterclockwise because it is engaged with both of the four long holes 107, the wire 36 is wound, and the rotating lever 33 is rotated clockwise in FIG.

Since the rotary lever 33 is fixed to the rotary shaft 32 and the interlocking lever 41 is fixed to the rotary shaft 32, the interlocking lever 41 rotates counterclockwise in FIG.
The pressing body 42 attached to the interlocking lever 41 moves to the right while being guided by the engagement between the guide groove 47 and the guide pin 45. At this time, since the latch 13 is at the half-latch position, the engaging piece 48 is at the left end position of the arc groove 47A, and the roller 46 of the moving pressing body 42 is
8, the latch 13 is forcibly rotated clockwise and displaced to the 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 rotated beyond the full latch position as shown in FIG. 10, the contact 30 of the switch body 26 is opened. Is turned off. The switch body 26 is O
When it becomes FF, the auto-close controller 120 considers that the latch 13 has rotated to the surplus rotation position, and thereby reverses the motor 40. Then wire 3
6, the rotating lever 33 rotates counterclockwise in FIG. 5 by the elasticity of the spring 39 to wind up the wire 36, the pressing body 42 also returns to the position of FIG. 4, and the latch 13 causes the spring 24 to move.
Is returned to the full latch position by the elastic force of, and the ratchet 14 is engaged with the full engagement stepped portion 31 of the latch 13 to complete the door closing. The motor 40 reversely rotated by turning off the switch body 26 causes the detector 130 to generate an abnormal current when the protrusion 100 of the rotating member 96 comes into contact with the end of the arc groove 99 of the base frame 58 to be in a mechanical lock state. Upon detection, power supply is stopped.

[Operation of Connector] In the above automatic door closing, the auto-close terminal 133a of the connector 129 on the vehicle body 1 side,
b and c are for door 3 before door 3 is half latched.
Side connector 124 auto-close terminal 134a,
so that they are in contact with b and c respectively and are electrically connected,
Although it is elastically projected outward, the signal contact terminal 133c and the plus side contact terminal 133a of the connector 129 are arranged so as to be largely separated from the minus side contact terminal 133b. Short circuit between terminals due to the metal body can be largely prevented.

[0030]

[Operation of Manual Door Closure] Next, the manual door closure will be explained. When the sliding door 3 in the open state is manually slid and strongly closed, the latch 13 of the lock body 8 causes the striker of the vehicle body 1 to be in a well-known manner. 10 to rotate to the full-latch position, the ratchet 14 is engaged to the full-engagement stepped portion 31 of the latch 13, and the closing of the door is completed. In this operation, as the latch 13 rotates, the switch body 26 is turned OFF / ON / O as described in the automatic door closing.
Although it changes to FF, when the latch 13 is closed so strongly that it rotates excessively, the change of the switch body 26 is made instantaneously, so that the motor 40 performs reverse rotation as an ending operation before moving almost. Become. Further, when the latch 13 closes the door with the strength of just becoming a full latch, the excessive rotation of the latch 13 cannot be detected. Therefore, the motor 40 performs the same operation as the automatic closing of the door, rotates the latch 13 excessively, and then returns to the original state. Become.

[0031]

[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 in FIG. 12 via the rod 63 or the rod 66. Then, since the pin 89 of the moving rod 86 is engaged with the engaging 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. 5 is rotated via the. 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 ratchet arm 49 with the connecting pin 51.
The ratchet 14 connected by is rotated to separate the ratchet 14 from the latch 13 and open the door.

[0032]

[Locking action] The lock lever 80 is rotated counterclockwise in FIG. 12 by the key cylinder 6 or the inside lock operating member 7 or the locking motor 90 so that the pin 89 of the moving rod 86 is moved to the empty swing groove 71 of the open lever 61. When you face it, it will be in a locked state. In this state, even if the door opening operation is performed, the pin 89 of the moving rod 86 only moves in the empty 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,
I can't open the door.

[0033]

[Manual Safety Mechanism] When a finger or the like is caught in the sliding door 3 during the operation of the automatic door closing, the outer handle 5 or the inner handle 65 is immediately operated to rotate the open lever 61. Then, the intermediate lever 108, which is in contact with the pin 113 of the open lever 61, rotates clockwise about the shaft 109, and the pin 119 of the moving rod 115.
Moves in the engaging groove 101 of the rotating member 96 in the direction away from the shaft 95 and into the idle vibration passage 103 on the tip side of the engaging 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 door 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 the door opening operation.

When a finger is caught when the slide lever 3 is closed with the lock lever 80 in the lock position, the open lever 61 is operated twice and the safety mechanism X is operated by the first operation. Lock lever 80
Is switched to the unlock position, and the door is opened by the second operation. That is, when the open lever 61 is operated when the lock lever 80 is in the lock position,
The intermediate lever 108 rotates clockwise, and the pin 1 of the moving rod 115
19 moves from the engagement groove 101 to the idling passage 103. 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 door is released. At this stage, since the lock lever 80 is in the lock position, the rotation of the open lever 61 is not transmitted to the transmission lever 74, so that the door cannot be opened. However, when the connection between the motor 40 and the latch 13 is cut off due to the operation of the safety mechanism X, the current value of the motor 40 sharply decreases. When the decrease is detected, it is considered that the safety mechanism X has operated, and the controller 120 operates the locking motor 90 via the cord 131 to switch the lock lever 80 to the unlock position.

Next, when the open lever 61 is operated again, the lock lever 80 has been switched to the unlock position, so that the transmission lever 74 also rotates and rotates the intermediate lever 52 of FIG. 5 via the rod 78. One end 55 of the rotated intermediate lever 52 has the other end 56 of the ratchet arm 49.
The ratchet arm 49 is rotated by contacting the ratchet arm 49, the ratchet 14 connected to the ratchet arm 49 by the connecting pin 51 is rotated, and the ratchet 14 is disengaged from the latch 13 to open the door. Therefore, according to the present invention, regardless of whether the lock lever 80 is in the locked position or the unlocked position, the automatic closing of the door can be stopped and the door can be opened by operating the open lever 61, thereby preventing a serious accident. it can.

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 portion 29 of the latch 13 and the elasticity of the spring 24 causes the latch 13 to open. Back to
Although the engagement with the striker 10 may be released, even in such a case, in the present invention, the motor 40 is a mechanism that normally rotates when the switch body 26 is turned on and reversely rotates when the switch body 26 is turned off. The forward rotation of 40 is only for a moment, and the latch 13 not engaged with the striker 10 is not rotated to the full latch position. Further, the detection of the overcurrent by the detector 130 has another effect. That is, when the motor 40 detects an overcurrent during forward rotation,
It is considered that the switch body 26 or the like is out of order, the motor 40 is immediately rotated in the reverse direction, and when the overcurrent is detected again, the motor 40 is stopped.

[0037]

[Door closing operation after the safety mechanism is activated] As described above, the motor 4
When the outer handle or the inner handle is operated to open the safety mechanism X while the door is forcibly closed by 0, the rotation of the open lever 61 causes the intermediate lever 108 to rotate clockwise, so that the pin 119 is engaged with the engaging groove 101. To move to the idling passage 103, and thereafter, the power of the motor 40 is not transmitted to the latch 13 side, the rotating member 96 becomes idling, and the forced closing is interrupted. Therefore, the door 3 is opened, but 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 power supply is cut off, so that the motor 40 stops there. FIG. 22 shows this state. In FIG. 22, the rotating member 96 rotated by the motor 40 is stopped at the position rotated in the counterclockwise direction from the initial position in FIG. 12, and the wire rotating arm 104 includes the wire 36 and the arrow of the spring 39. Since it receives the force in the A direction, it fully rotates in the clockwise direction with the pin 119 of the movable rod 115. Therefore, even if the door 3 is closed again and the motor 40 is energized and the motor 40 is normally rotated from the state of FIG. 22, the wire rotation arm 104 cannot be rotated in the door closing direction. Therefore, in the present invention, as described in the section of the action of the automatic door closing, when the switch body 26 is turned on by the door closing, the controller 1
20 first supplies a reverse current to the motor 40,
The rotating member 96 is rotated clockwise in FIGS. 12 and 22 to surely return it to the initial position. Thus, when the rotating member 96 is returned to the initial position, the pin 119 of the moving rod 115 is moved.
Is located at a position facing the engaging groove 101, the intermediate lever 108 is rotated by the spring 111, and the pin 119 is engaged with the engaging groove 1.
01 and engages with the rotating member 96 and the wire rotating arm 10
4 and 4 are connected. After this state, the motor 4
A forward current is supplied to 0. Therefore, the motor 40
The auto-close mechanism operates normally regardless of the position of the (rotating member 96).

The above explanation is that if the door 3 is closed again from the state of FIG. 22, the motor 40 moves, but when the safety mechanism X is activated, the motor 40 may also fail at the same time. . In this way, when the motor 40 also fails, the motor 40 does not rotate even if the door 3 is closed again, so 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 in a considerably rotated position. For this reason, if the intermediate lever 108 and the open lever 61 are directly connected, the open lever 61 is also fixed at a considerably rotated position, which affects the operation of the opening / closing door as described at the beginning. Therefore, in 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 come into contact with each other and the intermediate lever 108 becomes inoperable. Even if the open lever 61 can rotate independently of the position of clockwise rotation against the elasticity of 111, the open / close door operation is not affected.

[0039]
