Abstract

PURPOSE:To prevent definitely a door from being half-closed by allowing a pressure piece of a latch arm that rotates counter clockwise to come in contact with an arm of a motor switch so that it may be switched on and keeping an off state after it comes close to a full-latched state. CONSTITUTION:In an automatic door closing device which rotates a latch 13 with a motor after having closed a door with a hand up to a specified position, a pressure piece 27 of a latch arm 25 comes into contact with an arm 28 of a switch 26 at a half-latch position (illustrated position) so that the switch 26 may be turned on. After the latch 13 is further rotated counter clockwise and full-latched (a ratchet 14 is engaged with a full-latch means 31), the switch 26 is turned off. This construction makes it possible to prevent definitely the door from being half-closed.

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In the publicly known Japanese Patent Laid-Open No. 3-115676, when a door is manually closed to a half-latch state (so-called hand state), a switch body a is turned on to energize a motor b to rotate a latch c. In the automatic door-closing type lock device in which the door is closed in the full-latch state by operating the switch body a, the switch body a is rotated by the rotation of the ratchet d.
The technology that is configured to turn off and on is described (Fig. 2
1). As in the above-mentioned known technique, in the structure in which the switch body a is turned on / off by the rotation of the ratchet d to know the half-latch state and the full-latch state, the ratchet d forms the half-latch step e formed on the outer peripheral surface of the latch c. When the switch body a is turned on and engaged, the switch body a is turned on, and when the ratchet d is pulled out from the half latch step e and climbs on the inclined surface g, the switch body a is turned off and the full latch step f is reached.
When the switch body a is turned to and engaged, the switch body a is set to be turned on again. As a result, the switch body a is initially O
When it is N, it is known as a half-latch state. When the motor b is energized, the latch is rotated toward the full latch, and when it is turned on for the second time after a momentary OFF state, it is known as the full-latch state. b can be stopped or reversed. The above-mentioned known technology also has this configuration. Also,
In Japanese Patent Application Laid-Open No. 63-206582, filed by the applicant of the present invention, a moving contact mounted on a latch and rotating together with the latch is contacted with and separated from a plurality of fixed contacts fixed to the stationary member side. , A switch body adapted to detect the open position, the half-latch position, and the full-latch position of the latch.

[0003]

The former known technique has a problem in that the switch body a detects the rotation of the ratchet d. In the configuration in which the rotation of the ratchet d is detected, as described above, the first ON of the switch body a is regarded as the half-latch state, and the next ON is regarded as the full-latch state, but the second time. Is not always in the full-latch state, but may be in the half-latch state. That is, when the door is closed, the ratchet d engages the half-latch step e to turn on the switch body a, and then rides on the inclined surface g to turn off the switch body a, but the door closing force is insufficient. When sufficient, ratchet d has slope g
The latch c reverses from here without being able to get over
The ratchet d does not engage the full-latch step f but engages the half-latch step e again to turn on the switch body a again.
Set to N. This is a hand state that occurs extremely generally, and in such a case, since the switch body a is turned on twice with the OFF state interposed, it is actually a half latch state. Instead, the processing is performed as the full-latch state, and the original function of the automatic door-closing type lock device for preventing the hand state cannot be achieved. In addition, a problem occurs when the door is strongly closed. When the door is strongly closed, the latch c rotates vigorously, so that the ratchet d jumps over the half-latch step e without engaging with the half-latch step e and engages with the full-latch step f. In this case, since the engagement with the half-latch step e is insufficient, the switch body a is turned ON during the half-latch.
The switch body a is turned on only after the full latch step portion f is engaged. Since the first time is ON at the full latch time, an abnormal situation occurs in which the motor b starts driving in the full latch state. The latter known technique has a configuration in which a moving contact is slidably moved with respect to a plurality of fixed contacts. In this configuration, when the open position is switched to the half latch position, the half latch position is switched to the full latch position. The point that must be put in a non-detection state when changing, and the structure in which the moving contact itself is provided with elasticity so that the moving contact comes into contact with the fixed contact by this elasticity, this configuration provides sufficient elastic force for many years. It is difficult to secure, and it is difficult to act on the automatic door lock device. Furthermore, since a large number of contacts are used, the reliability is reduced, and the number of manufacturing processes and configurations are increased.

[0004]

According to the present invention, therefore, when the door is manually closed to a predetermined position, the switch body 26 is turned on, and thereafter, the power of the motor 40 rotates the latch 13 toward the full latch position to close the door. In the automatic door lock device, the switch body 26 is turned on / off depending on whether the latch 13 is rotated so as to be directly pressed by the outer peripheral portion of the switch 13 or by the latch arm 25 rotating together with the latch 13. In addition, the switch body 26 is turned off because it is not pressed before the vicinity of the half-latch, is continuously pressed between the vicinity of the half-latch and the vicinity of the full latch, and is turned on after the vicinity of the full-latch is released and is turned off. This is a switch used for the automatic door-closing type lock device of the door.

Turn 3 clockwise.

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 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 abuts on the engaging piece 48 of the latch 13 in the half-latch position to forcibly rotate the latch 13 in FIG. 4 to the full-latch position in FIG. 9. However, since the contact 30 is still pressed in the full latch position of FIG.
Continues to be energized, and when the rotation exceeds the full latch position as shown in FIG. 10, the contact 30 of the switch body 26 is opened and turned off. When the switch body 26 is turned off,
The controller 120 on the door side considers that the latch 13 has rotated to the excessive rotation position, and thereby causes the motor 40 to rotate in the reverse direction. Then, the rotation 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 returns to the full latch position by the elasticity of the spring 24.

The door is closed. When the arc groove 99 of the rotating member 96 abuts on the protrusion 100 of the base frame 58 to be in the mechanical lock state, the motor 40 reversely rotated by turning off the switch body 26 detects the overcurrent generated thereby. Then, the power supply is stopped.

[0029]

[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. It engages with 10 and rotates to the full-latch position, and the full-latch step 31 of the latch 13
The ratchet 14 is engaged with and the closing of the door is completed. In this operation, as the latch 13 rotates, the switch body 26 is turned ON / OFF as described in the automatic door closing. However, when the latch 13 is closed so strongly as to cause excessive rotation, the switch body 26 is turned ON. Even if the motor 40 rotates in the normal direction, the switch body 26 is turned off at the moment when the pressing body 42 slightly moves, whereby the motor 40 immediately reverses and returns to the original state. 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.

[Opening action] When opening the closed sliding door 3,
By operating the outer open handle 5 or the inner open 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 contacts the other end 56 of the ratchet arm 49 to rotate the ratchet arm 49,
The ratchet 14 connected to the above by the connecting pin 51 is rotated to release the ratchet 14 from the latch 13 and open the door.

[0031]

[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.

[Manual safety mechanism] If a finger or the like is caught in the sliding door 3 during the operation of the automatic door closing, immediately open the outer open handle 5 or the inner open handle 6
5 is operated to rotate the open lever 61. Then, the intermediate lever 108 directly connected to the open lever 61 by the pin 113 rotates clockwise about the shaft 109,
The pin 119 of the movable rod 115 is the engagement groove 10 of the cutout groove 101.
It moves from 2 to the idling groove 103. This allows pin 11
The connection state between the rotating member 96 and the wire rotating arm 104 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 door is released.
Further, since the open lever 61 is rotated by the outer open handle 5 or the inner open handle 65, the door opening operation is performed at the same time as the door opening operation.

When the sliding door 3 is closed in the locked state and a finger is caught, the rotation of the open lever 61 is not transmitted to the transmission lever 74, so the door cannot be opened, but the door is forcibly closed immediately. Can be stopped and a serious accident can be prevented. Also, when the sliding door 3 is closed, the latch 1 engaged with the striker 10
Although the ratchet 3 is rotated to the half-latch position, the ratchet 14 holds the half-latch step 2 of the latch 13.
9, the latch 13 may return to the open position due to the elastic force of the spring 24, and the engagement with the striker 10 may be released. 40 is a mechanism that rotates normally when the switch body 26 is turned on and reversely rotated when the switch body 26 is turned off.
The normal rotation of is only for a moment, and the latch 13 not engaged with the striker 10 is not rotated to the full latch position. In addition, for the detection of overcurrent by the detector 130,
There is another effect. That is, as described above, when the overcurrent is detected while the motor 40 is rotating in the reverse direction, the motor 40 is stopped on the assumption that the normal reverse operation is completed.
If the motor 40 detects an overcurrent during forward rotation, it is considered as a failure of the switch body 26 and the like, and the motor 40 is immediately rotated in the reverse direction.
When the overcurrent is detected again, the motor 40 is stopped.

As described above, according to the present invention, when the door is manually closed to a predetermined position, the switch body 26 is turned on, and thereafter the power of the motor 40 rotates the latch 13 toward the full latch position to automatically close the door. In the door closing type lock device, the switch body 26 is directly pressed by the rotation of the latch 13 at its outer peripheral portion or the latch 1
The switch body 2 is configured to be turned on / off by being pressed by a latch arm 25 that rotates together with the switch body 2.
Since 6 is not pressed before the vicinity of the half latch, it is OF
F, a switch used in an automatic door-closing lock device for a vehicle door, in which a pressure is continuously maintained between the vicinity of the half latch and the full latch and is continuously turned on, and after the vicinity of the full latch is released, the switch is turned off. Body 26
Is continuously O between the vicinity of the half latch and the vicinity of the full latch.
Since it is N and it is OFF in all other cases, the rotational position of the latch 13 can be reliably detected regardless of the strength of the door closing force, and ON / OFF switching can be performed instantly, making it suitable for automatic door-closing type lock devices. You can get a switch.
