[0002]

2. Description of the Related Art Conventionally, a vehicle door opening / closing mechanism for performing a latch operation by a motor to change a door from a half-latch state to a full-latch state or from a full-latch state to a half-latch state is shown in FIGS. Automatic door closing devices are known.

In FIGS. 11 to 13, a "U" -shaped striker 1 is laterally projected on a vertical pillar of an opening for a door of a vehicle body, and a striker is provided on a side end wall surface facing the vertical pillar of the door. A base 3 provided with an engagement hole 2 into which 1 enters is provided. Engagement holes 2 are formed at the corners of the base 3 that bend from the vertical plate portion 4 to the outer inclined portion. A latch 8 and a lock claw 9 (see FIG. 11) are arranged between the outer inclined portion 5 and the inner inclined portion 6 of the vertical plate portion 4 of the base 3.

A notch 10 is provided in the lower portion of the latch 8 so that the striker 2 can be inserted therein. The latch 8 is biased in the direction in which the engagement hole 2 and the notch 10 coincide with each other, and the notch 10 opens toward the striker 1 when the door is open. A closing lever 12 is provided after the protruding portion 11 formed on the upper portion of the latch 8. The close lever 12 is rotatably supported by the shaft 13 of the lateral plate portion 7 of the base 3 and is spring-biased behind the protrusion 11. The close lever 12 is connected to the gear 15 via the wire 14, and when the wire 14 is pulled in the arrow A direction in FIG. 11, the close lever 12 pushes the protrusion 11 of the latch 8 and the latch 8 rotates in the B direction. When the door is open, the latch 8 is rotated so that the notch 10 is opened toward the striker 1, and the protrusion 11 is closed by the closing lever 12.
Is out of the rotation area.

A lock claw 9 that engages with the latch 8 is rotatably attached to the lower edge of the engagement hole 2, and the lock claw 9 is biased by a spring so as to always contact the latch 8. The striker 1 has a notch 10 in the latch 8 when the door is closed.
When the latch 8 is pushed by the striker 1 to rotate, the lock claw 9 enters the notch 10, the protrusion 11 appears in the rotation region of the close lever 12, and the latch 8 enters the half-latch state 8a. Become. The striker 1 has a further engaging hole 2
As the latch 8 rotates, the lock claw 9 gets over the notch 10 and the latch 8 enters the fully latched state 8b.

A cam 17 is attached to the lock pawl 9 via a rotary shaft 16. The cam 17 turns on the half-latch switch 18 when the lock pawl 9 enters the notch 10 of the latch 8. The half latch switch 18 is turned on to rotate the motor 19 stored in the door in the normal direction.
When the motor 19 rotates in the normal direction, the close lever 12 rotates via the gear 15 and the wire 14, and the close lever 1
2 rotates the latch 8 in the full latch direction B. Cam 1
The protruding portion 17 a of No. 7 is pushed by the pressing piece 28 a of the open lever 28 pivotally supported by the vertical plate portion 4 of the base 3. The open lever 28 is pressed in the C direction by the rod 29 to rotate the cam 17 in the D direction, separates the lock pawl 9 from the latch 8, and brings the latch 8 into the unlatched state.

A full-latch switch 20 is provided at the full-latch position of the closing lever 12, and when the latch 8 is fully latched, the closing lever 12 turns on the full-latch switch 20. When the full latch switch 20 is turned on, the motor 19 rotates in the reverse direction and the closing lever 12
Is returned to the position not in contact with the protrusion 11 by the biasing force of the spring 11a.

A neutral switch 21 is provided in the vicinity of the gear 15 at the rotation start position of the gear 15. When the motor 19 pulls the wire 14, the gear 15 is separated and the neutral switch 21 is turned off. When the motor 19 reversely rotates and the gear 15 returns to the rotation start position, the gear 15 contacts and the neutral switch 21 is turned on, the reverse rotation of the motor 19 stops, and the gear 15 stops at the swing center position. To do.

Half latch switch 18, motor 19,
The full-latch switch 20 and the neutral switch 21 are connected via a control unit 22 to a connector 23a at the side end of the slide door. The connector 23a is brought into contact with a connector 23b provided at the door opening of the slide door so that the connector 23a is closed when the slide door is closed.
a and 23b are connected. The connector 23b is the timer 2
It is connected to the battery 25 via 4. The power supply switch 2 attached to the door opening side of the timer 24
6 is connected, and an upper roller 27 that is in contact with the power supply switch 26 is provided on the slide door side.

When the door is closed and the striker 1 becomes a half-latch, the power feed switch 26 comes into contact with the upper roller 27 and turns on, and the connectors 23a and 23b come into contact with each other to rotate the motor 19 in the full-latch direction and the timer 24. Starts measuring the time after the door is closed. The timer 24 measures the time after the door is closed and returns the motor 19 to the rotation start position via the control unit 22 when the full latch switch 20 is not turned on within a predetermined time.

Inside the door, an actuator dedicated to the open lever for pushing the rod 29 in the C direction is provided.
When the manual lever or the hand-operated switch near the driver's seat (both not shown) is pressed, the actuator operates and rod 2
9 is pushed in the C direction, the open lever 28 is rotated in the C direction, and the cam 17 is rotated in the D direction for releasing the latch. When the cam 17 is in the fully latched state, the protrusion 17a pushes the pressing piece 2
The lock claw 9 is brought into contact with the latch 8 at an angle at which it hits 8a. When the door is completely opened and power supply to the actuator is cut off, the actuator stops operating and the rod 29 returns to its original position. The rod 29 is also operated by a manual operation lever provided inside the door.

[0012]

However, in the case of such a conventional door opening / closing mechanism for an automobile, since the actuator for exclusive use of the open lever 28 and the motor 19 for exclusive use of the close lever 12 are housed in the slide door, the slide door is slid. The device inside the door becomes complicated and the number of parts increases, which requires labor and time for manufacturing and preparation, and is disadvantageous in reducing the weight of the vehicle body.

Therefore, if the control of the closing lever 12 and the control of the open lever 28 can be performed only by the motor 19, it is possible to solve these problems and it is advantageous in terms of manufacturing and weight reduction. In order to release the latch, the connectors 23a and 23b need to be always connected.

However, in the case of the sliding door, unlike the hinge type door, when the door opening and the sliding door are separated from each other and the connectors 23a and 23b are not in contact with each other, power supply is cut off and the motor 19 cannot operate.

Accordingly, when the rod 29 is pushed by the motor 19 when the closed slide door is opened, the motor 19 stops while pushing the rod 29, so that the lock pawl 9 remains separated from the latch 8 and slides. It is possible that the latch 8 cannot be fully latched even when the door is closed.

The present invention has been made in view of the above problems, and as a result of earnest research, the inventor has controlled the close lever and the open lever by one motor in the slide door to open the slide door. We have developed a vehicle door opening / closing mechanism that can return the open lever to its original position even when the power supply to the internal motor is cut off.

[0017]

In order to solve the above problems, an automobile door opening / closing mechanism according to the present invention is driven by a motor by a slide door and can swing from a neutral position in a forward rotation direction and a reverse rotation direction. And a long hole connected to the close lever via the first connecting means is formed in the gear. The long hole is formed in the close lever when the gear rotates from the neutral position in the forward direction. And extends in both the forward and reverse directions so as to be disengaged with the close lever when rotating in the reverse direction from the neutral position, and the rotation center line is parallel to the rotation center line of the gear near the gear. And a first claw portion whose free end is connected to the open lever through a second connecting means is provided.
The free end of the pawl is urged in a direction to return the open lever to the full-latch position and supported by the stopper. The free end of the first pawl is supported by the gear when the gear rotates in the forward direction. And engages with the first pawl when the gear rotates in the reverse direction, and turns the first pawl until the lock pawl separates from the latch and then disengages from the first pawl. A second claw portion is provided.

[0018]

According to the vehicle door opening / closing mechanism of the present invention, when the sliding door is closed, the latch rotates from the striker receiving posture to the half-latch side, and the gear further rotates in the forward rotation direction, the first connecting means. The gear and the close lever engage with each other via the lever, the close lever rotates the latch in the full latch direction, and the latch and the lock claw are in the full latch state. At this time, the first pawl portion is supported by the stopper, and the second pawl portion rides over the free end portion of the first pawl portion, so that no force is input to the open lever.

When the full latch of the slide door is released and the slide door is opened, when the gear reversely rotates by the motor, the second claw portion engages with the first claw portion to rotate the first claw portion, and the second claw portion is rotated. The open lever is rotated via the connecting means, and the lock pawl is separated from the latch. When the locking claw is released from the latch, the latch returns to the striker receiving direction by its own urging force, and the striker is disengaged. When the striker, the latch, and the lock claw are disengaged and the sliding door moves away from the door opening, power supply to the motor is cut off. However, in the region where the open lever rotates in the direction to release the lock pawl from the latch, the engagement between the second pawl portion and the first pawl portion is released, so that there is no input to the open lever and the lock pawl has its own urging force. Also, the open lever is separated from the cam while returning to the original position of the full latch state by the urging force of the first claw portion.

Therefore, the latch and the lock claw are in the engaged state of the striker receiving state, and when the slide door is closed, the latch and the lock claw are in the half-latch state. The gear that was stopped in the full-latch release state is turned on again when the sliding door is closed, so it rotates in the forward direction,
After reaching the neutral position, it further rotates in the forward direction to rotate the close lever to engage the latch and the lock claw in the fully latched state.

As a result, the motor 1 in the sliding door is
Control the close lever and open lever individually,
Even if the sliding door is opened and power supply to the motor inside the door is cut off, the open lever can be returned to its original position.

When the lock claw 39 enters the notch 40 of the latch 38, the cam 43 coaxially attached to the lock claw 39 pushes the pressing piece 44 a of the half latch switch 44. When the pressing piece 44a is pressed, the half-latch switch 44 is turned on, a signal indicating the half-latch state is transmitted to the control unit 22, and a signal for rotating the motor 19 in the forward direction is transmitted from the control unit 22. When the motor 19 rotates in the normal direction, the gear 33 moves to the arrow E in FIG.
When the rod 45 (first connecting means) is pulled, the close lever 46 rotates.

The closing lever 46 is pivotally supported on the upper portion of the base 36 so as to push the protruding portion 38a of the latch 38 from the half-latch state to the full-latch state, and is biased by a spring in a direction away from the protruding portion 38a of the latch 38. ing.
The close lever 46 is connected to the gear 33 via the rod 45.

The open lever 50 has an upper portion connected to a rod 49 (second connecting means) for automatic operation and a lower portion connected to a rod 52 for manual operation. The connecting hole 53 of the rod 52 is an elongated hole extending in an arc shape.
The pulling operation of 9 and the pressing operation of the rod 52 can be selectively performed. The rod 49 is connected to the free end portion 34 a of the first claw portion 34. The rotation of the open lever 50 is restricted by the protrusion 50a hitting the stopper 50b. The rotation of the cam 43 is restricted by the stopper 50b.

The gear 33 has fan-shaped portions above and below the center of rotation, and an oblong hole 47 extending in an arc shape is opened in the fan-shaped portion above the gear 33. Gear 33 has a center line 33a
The elongated hole 47 extends in the left-right direction of the center line 33a. In FIG. 1, the gear 33 is drawn using partially broken lines to show the shapes of the first claw portion 34 and the second claw portion 35.

A first claw portion 34 having a rotation center line parallel to the gear 33 is disposed on the side of the gear 33, and the base of the first claw portion 34 is a stay supported by a frame of a slide door or the like. It is rotatably supported by 48. First claw 3

4 and the second claw portion 35 include the free end portion 34a and the jaw portion 34.
Needless to say, b is engaged with the hook portion 35a, but is bent in the thickness direction so that the rotation regions do not interfere with each other.

Next, the posture change of the gear 33 and the operation of the close lever 46 and the open lever 50 will be described with reference to FIGS.
Will be explained.

First, when the sliding door is changed from the open state to the closed state, the power supply to the sliding door is cut off, so that the gear 33 is stopped in the posture shown in FIG. When the sliding door is closed manually or by a driving means (not shown) and the sliding door is in the half-latch state,
Since electric power is supplied, electric power can be supplied to the motor 19.
When the pressing piece 44a is pushed by the cam 43 and the half-latch switch 44 is turned on, the gear 33 moves to the position shown in FIG. 3 → FIG. 4 → FIG. 5 →
In the order shown in FIG. 6, the second pawl portion 35 moves toward the first pawl portion 34 side in the normal rotation, and the second pawl portion 35 gets over the first pawl portion 34 (see FIG.
→ Figure 6). When the gear 33 further rotates in the normal direction, the rear end of the elongated hole 47 of the gear 33 pulls the rod 45 to rotate the close lever 46, and the latch 38 is brought into the full latch state, as shown in FIG. After the latch 38 is fully latched, the motor 19 is reversely rotated by the operation of the full latch switch, as shown in FIG.
The gear 33 is returned as shown in.

The rotation angle of the gear 33 in the forward and reverse directions is adjusted by controlling the power supply time to the motor 19 or controlling the current direction by the control unit 22. The rotation angle of the gear 33 can be adjusted by controlling the power supply time to the motor 19 by the control unit 22,
The forward / reverse rotation direction control of the gear 33 can be performed by controlling the current direction to the motor 19. The energization time control and the current direction control of the control unit 22 can be sufficiently performed by a known circuit.

When the posture of the gear 33 returns to the posture shown in FIG. 7, the center line 33a of the gear 33 is aligned with the gear 33.
Is located at the return position N (neutral position), the long hole 47 and the rod 45 are engaged with each other, and the first claw portion 34 is engaged with the second claw portion 35.

When the slide door is closed, power is being supplied to the motor 19, so that the gear 33 has returned to the returning posture shown in FIG. 7 to 10 when the full latch of the latch 38 is released and the sliding door is opened.
The gear 33 rotates to the state shown in.

That is, when the automatic operation button for releasing the full latch near the driver's seat is pressed, the motor 19 rotates in the reverse direction and the gear 33 rotates in the reverse direction as shown in FIG. As a result, the hook portion 35a of the second pawl portion 35 becomes the first
The gear 33 rotates while pulling the jaw portion 34b of the claw portion 34, and the open lever 50 rotates in the arrow F direction (FIG. 1) of FIG. 1 via the rod 49 connected to the first claw portion 34. In the full-latch state, the protrusion 43a of the cam 43 pushes the pressing piece 51 downward, but since the open lever 50 moves in the direction of arrow F, the lock claw 39 integrated with the cam 43 is separated from the latch 38. Start turning.
When the gear 33 pulls the rod 49 sufficiently as shown in FIG. 8, the cam 43 rotates and the lock pawl 39 separates from the latch 38,
The latch 38 becomes free and the striker comes off. As a result, the latch is released as shown in FIG. Even after the latch is released, as shown in FIG. 10, the motor 19 rotates due to inertia to slightly rotate the gear 33, the hook portion 35a of the second claw portion 35 rides over the jaw portion 34b of the first claw portion 34, and the hook is pulled. The engagement between the portion 35a and the jaw portion 34b is disengaged. First claw 3
4 is biased by a spring and regulated by a stopper 48a, and the second pawl portion 35 is biased by a spring so as to abut against the stopper 33b, so that the postures shown in FIG. 3 are obtained. When the slide door is completely opened by releasing the latch, the power supply to the motor 19 is cut off, so that the gear 33 stops while maintaining the posture shown in FIG. 3 until the slide door is closed again.

As described above, in the vehicle door mechanism of this embodiment, the sliding door is provided with the gear 33 which is driven by the motor 19 and can be swung, and the gear 33 is formed with the elongated hole 47. The hole 47 extends in both directions of forward and reverse rotation of the gear 33, and a first claw portion 34 having a free end 34a connected to the open lever 50 is disposed near the gear 33, and the first claw portion 34 is also provided. The free end portion 34a is urged in the direction of returning the open lever 50 to the full latch position and supported by the stopper 48a, and the gear 33 is provided with the second claw portion 35.

Therefore, when the closing lever 46 is turned, the elongated hole 47 and the closing lever 46 are inserted through the rod 45.
However, the second claw portion 35 does not engage with the first claw portion 34, and the first claw portion 34 is supported by the stopper 48a and does not rotate. When the gear 33 returns to the neutral position after turning the close lever 46, the first claw portion 34 and the second claw portion 35 are disengaged from each other, and since there is the elongated hole 47, the close lever 46 moves the gear 33. The spring is biased by the closing lever 46 itself and returns to its original position without being subjected to the resistance of. Gear 3
When 3 rotates in the reverse direction from the neutral position, the second claw 3
5 engages with the first pawl portion 34 and pulls the first pawl portion 34 in the direction away from the stopper 48a, so that the open lever 50 rotates via the rod 49 and the full latch is released.
After the full latch is released, the first claw portion 34 and the second claw portion 35 are disengaged from each other.
Even if the gear 33 is tilted and stopped as shown in FIG. 3, the first claw portion 34 returns until it is supported by the stopper 48a by its own biasing force.

As a result, the motor 1 in the slide door is
Even with one 9, the close lever 46 and the open lever 5
The open lever can be returned to the original position even when the sliding door is opened and the power supply to the motor 19 is cut off.

[0041]

According to the vehicle door opening / closing mechanism of the present invention, the gear has an elongated hole, and the elongated hole and the closing lever are connected to each other when the close lever is rotated in the forward rotation direction from the neutral position. However, since the second claw portion rides over the first claw portion, the second claw portion does not engage and the first claw portion is supported by the stopper and does not rotate. Since there is an elongated hole when the gear returns to the neutral position after turning the close lever, the close lever does not receive input from the gear. When the gear rotates in the reverse direction from the neutral position, the second claw portion engages with the first claw portion and pulls the first claw portion away from the stopper, so that the open lever rotates and the lock claw and the latch separate from each other. ， Full latch is released. After the full latch is released, the engagement between the first claw portion and the second claw portion is released. Therefore, even if there is a sliding door and the power supply to the motor is stopped, even if the gear is stopped in a tilted state, the first claw portion returns until it is supported by the stopper by its own urging force.

As a result, the motor 1 in the slide door is
Control the close lever and open lever individually,
Even if the sliding door is opened and power supply to the motor inside the door is cut off, the open lever can be returned to its original position.
