It is possible to move to a lock position shown in FIG. 6 that moves downward by a predetermined distance from the unlock position and places the lock mechanism in a locked state.

  Note that the “lock mechanism” used in the description of the present embodiment includes the first and second lock levers 15 and 16 and the engagement pin 33 described later. The lock levers 15 and 16 and the engagement pin 33 are in unlock positions described later, respectively, and indicate that the door D can be opened based on the opening operation of the outside handle OH and the inside handle IH. "The first and second lock levers 15 and 16 and the engaging pin 33 are in the lock positions described later, respectively, and the opening operation of the outside handle OH and the inside handle IH is invalidated and the door D cannot be opened. Refers to the state.

  The “child mechanism” includes the child lock lever 4 and the engagement pin 18, and the “child unlock state” means that the child lock lever 4 and the engagement pin 18 are in a child unlock position described later. When the “lock mechanism” is in the “unlocked state”, the door D can be opened based on the opening operation of the inside handle IH. The “child lock state” refers to the child lock lever 4 and the engagement mechanism. This indicates a state where the door D cannot be opened by disabling the opening operation of the inside handle IH even when the combined pin 18 is in a child lock position described later and the “lock mechanism” is in the “unlocked state”.

  The locking actuator AC1 switches the locking mechanism between the unlocked state and the locked state with the power of the motor. The locking actuator AC1 decelerates the rotation of the motor (not shown) in the housing fixed to the lower part of the base plate 2 and the motor. And an operation lever provided at an appropriate position of the vehicle or a portable wireless operation switch lock, which is configured by pivotally supporting an output lever 20 for outputting the rotation of the reduction gear outside the housing.・ It operates by unlocking operation.

  The release actuator AC2 allows the door D to be opened and closed by releasing the fully-open door latch device DL3 and the fully-closed door latch devices DL1 and DL2 through various elements when the lock mechanism is unlocked. An output for outputting the rotation of the reduction gear to the outside of the housing, and a motor (not shown) incorporated in the housing fixed to the rear portion of the base plate 2 and a reduction gear for reducing the rotation of the motor. The lever 21 is pivotally supported and operated by operating a wireless operation switch.

  The inside handle IH is fixed to the inner end of the inside handle shaft 22 in the front-rear direction pivotally supported by the base plate 2, and moves backward (opening direction) from the neutral position shown in FIG. 2 when opening the door D. It swings by a predetermined angle and swings by a predetermined angle from the neutral position to the front (closing direction) during the closing operation when closing the door D.

  The inside lever 3 is pivotally supported by the inside handle shaft 22 on the upper portion of one side surface of the base plate 2 so as to be able to rotate integrally with the inside handle IH and the inside sub-lever 6, and at the initial stage (state in which nothing is operated) 4) is held in the neutral position together with the inside handle IH by the biasing force of the spring 30 acting on the inside sub-lever 6, and against the biasing force of the spring 30 by opening the inside handle IH. As shown in FIG. 8, it opens clockwise from the neutral position shown in FIG. 8, and closes from the neutral position counterclockwise as shown in FIG.

  As can be understood from FIGS. 14 and 15 in particular, the inside sub-lever 6 is formed in a square hole 6a formed in a substantially central portion of the square column part 22a of the inside handle shaft 22 protruding from the bearing hole 2a of the base plate 2 to the vehicle outer side. By being fitted and fixed in a non-rotatable manner, it is supported on the vehicle exterior side of the base plate 2 so that it can rotate integrally with the inside handle shaft 22. Further, the inside lever 3 has a cylindrical portion 22b of the inside handle shaft 22 inserted into a bearing hole 3d formed in a substantially central portion of the inside lever 3, and a bent portion 6b facing the vehicle inner side of the inside sub lever 6 is formed on the base plate 2. By passing through the arc-shaped long hole 2 b and fitting into the hole 3 e of the inside lever 3, the inside handle shaft 22 is supported so as to rotate integrally with the inside sub-lever 6.

  Since the inside handle shaft 22, the inside lever 3 and the inside sub lever 6 rotate together with the operation of the inside handle IH, the inside sub lever 6 is set so as not to impair the function. The inside lever 3 may be directly fixed to the inside handle shaft 22 so as not to be relatively rotatable.

  Further, the inside lever 3 is connected to the arcuate elongated hole 3a provided in the upper portion by connecting the front end portion of the connecting rod 51 connected to the closing inside lever 13 so as to be relatively movable in the front-rear direction. The closing operation by the closing operation of the handle IH can be transmitted to the closing inside lever 13 through the connecting rod 51, and the opening portion by the opening operation by the opening operation of the inside handle IH is a bent portion 3b provided at the rear side. 8 is made to abut on the abutting portion 8a from above, and the opening inside lever 8 is released in the counterclockwise direction (see FIG. 8).

  A slider 19 is supported below the inside lever 3 so as to be movable up and down. As will be described later, the slider 19 is interlocked with the movement of the child lock lever 4 to each position. Particularly, as shown in FIG. 12, when the child lock lever 4 is in the child unlock position, the inside handle detection lever 17 is provided. When the child lock lever 4 is moved to the child lock position, as shown in FIG. 13, the child unlock position is located above the child unlock position. It moves to the child lock position where it is displaced and retracts outside the movement locus of the tip 17a.

  The inside handle detection lever 17 is pivotally supported by a switch case 40 fixed to the lower part of the base plate 2 by a shaft 28 in the vehicle interior / exterior direction and, for example, a spring 37 (see FIG. 5) from a neutral position shown in FIGS. It can be rotated clockwise by a predetermined angle against the urging force (counterclockwise in FIG. 5), and the rotation is transmitted to the inside handle sensor SW1.

  The inside handle sensor SW1 is installed in the switch case 40 and is switched from off to on by transmitting a clockwise or counterclockwise rotation from the neutral position of the inside handle detection lever 17, and is mounted on the vehicle. An open signal or a close signal that triggers activation of the electric door opening and closing device PSD is transmitted to the control device.

  The control device receives the opening signal from the inside handle sensor SW1 to drive control the electric door opening / closing device PSD in the opening direction, and similarly receives the closing signal to move the electric door opening / closing device PSD in the closing direction. Drive control.

  As shown in FIGS. 4 and 12, when the slider 19 is in the child unlocked position, that is, when the child mechanism is in the child unlocked state, the contact portion 19 a of the slider 19 is moved to the inside handle as the inside lever 3 is opened. By contacting the upper end portion 17a of the detection lever 17 from the rear side, the inside handle sensor lever 17 is turned counterclockwise by a predetermined angle from the neutral position shown in FIGS. Further, as the inside lever 3 is closed, the contact portion 3c provided at the lower portion of the inside lever 3 contacts the upper end portion 17a from the front side, so that the inside handle detection lever 17 is rotated clockwise by a predetermined angle from the neutral position. By moving, the inside handle sensor SW1 is switched on.

  As shown in FIGS. 7 and 13, when the slider 19 is in the child lock position, that is, when the child mechanism is in the child lock state, the slider 19 is retracted out of the movement locus of the upper end portion 17 a of the inside handle detection lever 17. ing. Thereby, even if the inside lever 3 is opened, the inside handle detection lever 17 is held at the neutral position and does not switch the inside handle sensor SW1, but when the inside lever 3 is closed, the inside handle 3 is in contact. When the portion 3c comes into contact with the upper end portion 17a from the front side, the inside handle sensor lever 17 is turned clockwise by a predetermined angle from the neutral position, and the inside handle sensor SW1 is switched on.

  That is, when the child mechanism is in the child unlocked state, the inside handle sensor SW1 is turned on based on the opening and closing operations of the inside lever 3, and outputs a signal that triggers the activation of the electric door opening and closing device PSD. When it can be transmitted to the control device and is also in the child lock state, a signal that triggers activation of the electric door opening / closing device PSD cannot be transmitted by the opening operation of the inside lever 3, and the electric door is based only on the closing operation. A signal that triggers activation of the switching device PSD can be transmitted to the control device.

  The closing inside lever 13 is pivotally supported on the base plate 2 by a shaft 25, and a lower portion of the shaft 25 is connected to the elongated hole 3a of the inside lever 3 through the connecting rod 51 described above, and is bent at the lower portion. A contact portion 10c, which will be described later, of the second outside lever 10 can come into contact with the portion 13a from the rear side, and the lowermost portion is connected to the fully-open door latch device DL3 via an operation force transmission member 61 constituted by a Bowden cable or the like Is done. Thereby, the closing inside lever 13 is shown in FIG. 4 based on the closing operation of the inside lever 3 by the closing operation of the inside handle IH and the releasing operation of the second outside lever 10 by the opening operation of the outside handle OH, which will be described later. The release operation is performed clockwise from the initial position (see FIG. 10).

  In the state where the fully open door latch device DL3 is engaged with the striker and the door D is held at the fully open position, when the closing inside lever 13 is released as shown in FIG. The release operation is transmitted to the fully-open door latch device DL3 via the operation force transmission member 61. The fully open door latch device DL3 is detached from the striker and allows the door D to move in the closing direction. When the inside lever 3 is closed based on the closing operation of the inside handle IH, the bent portion 3b of the inside lever 3 moves in a direction away from the contact portion 8a of the opening inside lever 8. The closing operation of the lever 3 is not transmitted to the opening inside lever 8.

  The opening inside lever 8 is pivotally supported by the base plate 2 by a shaft 24, and the bent portion 3b abuts against the abutting portion 8a from the upper side as the inside lever 3 is opened clockwise. In conjunction with the opening operation of the lever 3, the release operation is performed counterclockwise from the initial position shown in FIG. 4 (see FIG. 8).

  As shown in FIG. 8, the release operation of the opening inside lever 8 is transmitted to the emergency lever 9 by the contact portion 8 c provided at the lower portion coming into contact with a part of the emergency lever 9 counterclockwise, When the child mechanism is in the child unlocked state, it is transmitted to the sub lever 11 via the engagement pin 18, and when it is also in the child locked state, it is not transmitted to the sub lever 11.

  In the upper part of the opening inside lever 8, a long hole 8b in the vertical direction is provided. In the long hole 8b, when the child lock lever 4 is in the child unlock position, the release operation of the opening inside lever 8 can be transmitted to the sub lever 11, especially the child unlock position shown in FIGS. In particular, an engagement pin 18 movable to a child lock position shown in FIGS.

  In particular, as clearly shown in FIGS. 12 and 13, the engagement pin 18 slides in the longitudinal hole 4 a provided in the rear part of the child lock lever 4 and the longitudinal hole 8 b in the opening inside lever 8, respectively. Engage possible. Thus, as shown in FIG. 12, when the child lock lever 4 is in the child unlock position, the engagement pin 18 is in the child unlock position facing the contact portion 11b provided on the upper portion of the sub lever 11. Thus, the engaging pin 18 moves forward with the release operation of the opening inside lever 8 and contacts the contact portion 11b from the rear side, so that the release operation of the opening inside lever 8 is transmitted to the sub lever 11. In addition, as shown in FIG. 13, when the child lock lever 4 is moved to the child lock position, the child lock does not face the contact portion 11b because the engagement pin 18 moves upward from the unlock position. In this position, even if the engagement pin 18 moves forward with the release operation of the opening inside lever 8, it does not contact the contact portion 11b. Releasing operation of the opening inside lever 8 is not transmitted to the sub-lever 11.

  The emergency lever 9 is pivotally supported on the base plate 2 by a shaft 24, and an end connecting portion 9a is connected to an emergency mechanism portion (emergency lever) of the fully-closed door latch device DL2 via an operating force transmission member 62. Thus, regardless of whether the locking mechanism is in the unlocked state or the locked state, the spring 35 is moved from the initial position shown in FIG. 4 based on the opening operation of either the outside handle OH or the inside handle IH as described later. 8 is released counterclockwise as shown in FIG. 8, and the release operation is transmitted to the emergency mechanism portion of the fully-closed door latch device DL2 via the operation force transmission member 62. The emergency mechanism section interrupts the closing operation by cutting the transmission path between the closer mechanism section and the latch mechanism section in the fully closed door latch device DL2.

  The first outside lever 7 is pivotally supported by the switch case 40 by a shaft 23 facing inward and outward of the vehicle, and the upper end of the connecting portion 7a at the front end is connected to the outside handle OH in the vertical direction.

Is done. Thus, when the outside handle OH is operated and the operating force transmission member 63 moves downward, the first outside lever 3 moves counterclockwise from the initial position shown in FIG. 4 against the biasing force of the spring 36. The release operation is performed, and the release operation is transmitted to the second outside lever 10 via the connecting rod 53.

  The outside handle sensor S <b> 3 is switched from off to on by contacting the detection unit 7 c provided at the lower part of the first outside lever 7 with the release operation of the first outside lever 7. If the lock mechanism is unlocked at that time, the control device performs drive control of the release actuator AC2 based on the ON signal of the outside handle sensor SW3, and then performs drive control of the electric door opening and closing device PSD. In addition, when the lock mechanism is in a locked state, if communication between the driver's portable key and an ECU (Electronic Control Unit) mounted on the vehicle is established, an open signal of the outside handle SW3 is output. Based on this, after unlocking drive control of the locking actuator AC1 and switching the locking mechanism to the unlocked state, the drive control of the release actuator AC2 and the electric door opening and closing device PSD is performed. No response is made even if an ON signal of the handle SW3 is received.

  The second outside lever 10 is pivotally supported on the base plate 2 by a shaft 24, and a connecting rod 54 connected to the output lever 21 of the release actuator AC1 is slidable in a longitudinal hole 10a provided in the lower part.

  The release operation of the second outside lever 10 is transmitted to the sub lever 11 by the claw portion 10b provided at the rear portion of the second outside lever 10 coming into contact with the bent portion 11a provided at the sub lever 11 from the lower side. The contact portion 10c abuts against the bent portion 13a of the closing inside lever 13 from the rear side to transmit to the closing inside lever 13 and release the closing inside lever 13.

  When the second outside lever 10 is released based on the release operation of the first outside lever 7, the front end of the connecting rod 54 is relatively within the elongated hole 10 a of the second outside lever 10. The release operation of the second outside lever 10 is not transmitted to the output lever 21 of the release actuator AC1. Further, when the second outside lever 10 performs the release operation based on the driving of the release actuator AC1, the front end portion of the connecting rod 53 relatively moves in the long hole 7b of the first outside lever 7. Only the release operation of the second outside lever 7 is not transmitted to the first outside lever 7.

  The sub lever 11 is pivotally supported by the base plate 2 by a shaft 24, and the claw portion 10b of the second outside lever 10 abuts on the bent portion 11a of the sub lever 11 from the lower side so that the outside handle OH can be opened. In conjunction with the release operation of the second outside lever 10 based on this, the release operation is performed in the counterclockwise direction against the biasing force of the spring 35 from the initial position shown in FIG.

  As shown in FIG. 4, when the child lock lever 4 and the engagement pin 18 are in the child unlock position, the engagement pin 18 is moved forward by the release operation of the opening inside lever 8. When 18 is in contact with the contact portion 11b of the sub lever 11 from the rear side, the release operation of the opening inside lever 8 is transmitted to the sub lever 11, and the sub lever 11 is operated when the outside handle OH is opened. Release operation is performed in the same way as. On the other hand, as shown in FIG. 7, when the child lock lever 4 and the engagement pin 18 are in the child lock position, the engagement pin 18 cannot be brought into contact with the contact portion 11b.

Is in the unlocked position and the locking mechanism is in the unlocked state, in conjunction with the release operation of the sub-lever 11, the release operation is performed counterclockwise from the initial position shown in FIG. 4 (see FIG. 8). As shown in FIG. 6, when the engaging pin 33 and the first and second lock levers 15 and 16 are in the locked position and the lock mechanism is in the locked state, the sub lever 11 is Engagement pin 33 does not move only from the initial position moves relatively transverse bore of the control holes 12 be leased operation. When the release lever 12 performs a release operation, the release operation is transmitted to the fully closed door latch devices DL2 and DL1 via the operation force transmission members 64 and 65, and the fully closed door latch devices DL2 and DL1 perform a release operation. The door D in the fully closed position can be opened.

  The first lock lever 15 is pivotally supported on the surface of the base plate 2 facing the vehicle inner side by a shaft 27, and the connecting portion 15a at the rear end is connected to the lock operation knob LK via the connecting rod 52 in the vertical direction. The lower end connecting portion 15b is connected to the upper end portion of the output lever 20 of the locking actuator AC1. As a result, the first lock lever 15 resists the urging force of the turnover spring 32 supported by the base plate 2 by the manual operation of the lock operation knob LK and the operation of the output lever 20 by the power of the lock actuator AC1. It moves to the unlock position shown in FIG. 4 that enables the opening operation of the outside handle OH and the inside handle IH and the lock position shown in FIG.

  The second lock lever 16 is pivotally supported by a shaft 27 together with the first lock lever 15 on the surface facing the vehicle inner side of the base plate 2, and the first lock lever 15 is manually operated by the lock operation knob LK or the lock actuator AC1. When it is moved from the unlocked position to the locked position by electric operation, it moves from the unlocked position to the locked position together with the first lock lever 15 by contacting the projection 15c (see FIG. 5) of the first lock lever 15. Similarly, when the first lock lever 15 moves from the lock position to the unlock position, the biasing force of the spring 34 with one end hooked to the first lock lever 15 and the other end hooked to the second lock lever 16 respectively. Within the range, the first lock lever 15 moves in the unlocking direction. The urging force of the spring 34 acting between the first lock lever 15 and the second lock lever 15 is set to be smaller than the urging force of the turnover spring 32.

  The second lock lever 16 is provided with a long hole 16a in which the engagement pin 33 is engaged so as to be relatively slidable in the front-rear direction. When the second lock lever 16 is in the unlock position as described above, the engagement pin 33 is in the unlock position to engage with the vertical hole portion of the control hole 12 of the release lever 12 as shown in FIG. In addition, when the second lock lever 16 moves to the lock position, the second lock lever 16 moves to the lock position located in the lateral hole portion of the control hole 12 as shown in FIG.

  When the engagement pin 33 is in the unlocked position, as shown in FIG. 8, the release of the sub lever 11 is brought into contact with the vertical hole portion of the control hole 12 in the counterclockwise direction as the sub lever 11 is released. The operation can be transmitted to the release lever 12, and if it is also in the locked position, the lateral hole portion of the control hole 12 is relatively moved so that the release operation of the sub lever 11 is not transmitted to the release lever 12. Therefore, when the lock mechanism is in the unlocked state, the door D can be opened by releasing the fully-closed door latch devices DL2 and DL1 based on the opening operation of the outside handle OH and the inside handle IH. When the lock mechanism is in the locked state, the door D cannot be opened based on the opening operation of the outside handle OH and the inside handle IH.

As shown in FIGS. 14 and 15, the child lock lever 4 is disposed on the vehicle outer side than the inside lever 3, and the cylindrical portion 22 b of the inside handle shaft 22 can be rotated relative to the bearing hole 4 e of itself through a collar 38. By being fitted, the inner handle shaft 22 is supported so as to be relatively rotatable. The front end portion of the child lock lever 4 is provided with a hook-like operation portion 4b exposed from the operation hole D1 provided in the front end surface of the door D when the door D is opened, and the engagement pin 18 described above is provided at the rear portion. Is provided with a long hole 4a which is inserted so as to be movable in the front-back direction. When the operation portion 4b is locked (operated downward in FIG. 4) with the door D opened, the child lock lever 4 rotates counterclockwise around the shaft 22 from the child unlock position shown in FIG. When the operation portion 4b is unlocked (upward in FIG. 7), the shaft 22 is moved from the child lock position shown in FIG. 4 is rotated clockwise by a predetermined angle to move to the child unlock position shown in FIG.
The operation unit 4b has a size that allows the operation hole D1 to be closed from the inside of the door D at any position, and a finger can be inserted into the surface (a surface exposed from the operation hole D1). An operation recess 4d of a large size is formed, and a shape in which no protrusion is formed is exhibited. Therefore, the operation of the child lock lever 4 is performed in a state in which the finger is inserted into the operation recess 4d formed in the operation unit 4b.

  As shown in FIGS. 14 and 15, the switch lever 5 is disposed between the base plate 2 and the child lock lever 4, and the cylindrical portion 22b of the inside handle shaft 22 rotates relative to the bearing hole 5c of itself through a collar 38. By being fitted to each other, the inner handle shaft 22 is pivotally supported so as to be relatively rotatable. A contact portion 5a close to the engagement pin 18 is provided at the tip of the arm extending rearward of the switch lever 5, and a detection portion 5b whose operation is detected by the child sensor SW2 is also provided at the lower portion. Provided.

  When the child lock lever 4 is in the child unlock position, the engagement pin 18 can contact the contact portion 11b of the sub lever 11 from the rear side as shown in FIGS. In the child unlock position where it is impossible to contact the contact portion 5a of the lever 5, and in the same lock position, as shown in FIGS. Therefore, it is in the child lock position where it cannot contact and can contact the contact portion 5a of the switch lever 5 from the rear side.

  As a result, the release operation of the opening inside lever 8 can be transmitted to the sub lever 11 via the engagement pin 18 when the child lock lever 4 is in the child unlock position, but cannot be transmitted to the switch lever 5. In the same manner, when the child lock position is reached, transmission to the sub lever 11 is impossible via the engagement pin 18 while transmission to the switch lever 5 is possible.

  As shown in FIG. 9, the switch lever 5 receives the release operation of the opening inside lever 8 via the engagement pin 18 and resists the urging force of the spring 37 from the initial position shown in FIGS. Turn counterclockwise.

  The child sensor SW2 is installed in the switch case 40 and is normally in an off state. When the child mechanism is in the child lock state, the switch lever 5 rotates as shown in FIG. Is switched from OFF to ON and the ON signal is transmitted to the control device.

  The child lock link 14 is pivotally supported on the base plate 2 by a shaft 26, and a longitudinal hole 14a provided in the front portion is connected to a connecting shaft portion 4c provided in a side surface of the child lock lever 4, and provided in the rear portion. The long hole 14 b in the front-rear direction is connected to a connecting shaft portion 19 b provided on the side surface of the slider 19. Thereby, when the child lock lever 4 is in the child unlock position, the child lock link 14 is in the child unlock position with the slider 19 as the child unlock position, particularly as shown in FIGS. Further, when the child lock lever 14 is moved to the child lock position, the slider 19 is rotated counterclockwise by a predetermined angle about the shaft 26, so that the slider 19 is moved to the child lock position, particularly as shown in FIGS. Move to the child lock position. That is, the child lock link 14 has a function for transmitting the rotation of the child lock lever 4 to each position to the slider 19.

Next, operation | movement of the operating device 1 in this embodiment is demonstrated based on FIGS.

(When the outside handle OH is opened in the state shown in FIG. 4 when the door D is in the fully closed position)
In the state shown in FIG. 4, when the outside handle OH is opened, the opening operation is transmitted to the first outside lever 7 via the operating force transmission member 63. As a result, the first outside lever 7 is released counterclockwise about the shaft 23, and the release operation is transmitted to the second outside lever 10 via the connecting rod 53, and the detection unit 7c is out. It contacts the side handle sensor SW3. The second outside lever 10 is released counterclockwise around the shaft 24 against the urging force of the spring 35. The release operation is transmitted to the sub lever 11, the emergency lever 9, and the release lever 12. The release operation of the release lever 12 is transmitted to the fully closed door latch devices DL2 and DL1 via the operation force transmission member 64. As a result, the fully-closed door latch devices DL2 and DL1 can open the door D by performing a release operation, and the control device drives the electric door opening and closing device PSD to open based on the open signal of the outside handle detection sensor SW3. Take control.

(When the door D is fully closed and the inside handle IH is opened in the state shown in FIG. 4)
When the inside handle IH is opened in the state shown in FIG. 4, the opening operation is transmitted to the inside lever 3 via the inside handle shaft 22. As shown in FIG. 8, the inside lever 3 is released from the neutral position about the inside handle shaft 22 in the clockwise direction against the biasing force of the spring 20, and the release operation is opened via the bent portion 3b. And is transmitted to the inside handle sensor SW1 through its own contact portion 3c and the inside handle detection lever 17.

  The opening inside lever 8 performs a release operation in the counterclockwise direction centering on the shaft 24 and the spring 35, and transmits the release operation to the engagement pin 18, the sub lever 11, the release lever 12 and the emergency lever 9. In this state, the engagement pin 18 moves forward with the release operation of the opening inside lever 8, but the engagement pin 18 cannot contact the contact portion 5 a of the switch lever 5. Since it is in the position, it does not come into contact with the contact portion 5a even if it moves forward. Therefore, the switch lever 5 does not operate.

  The release lever 12 performs a release operation in conjunction with the release operation of the opening inside lever 8, so that the release operation is fully performed via the operation force transmission member 64 through the fully-closed door latch device DL <b> 2 and the operation force transmission member 65. Each is transmitted to the closed door latch device DL1. Thereby, the fully-closed door latch devices DL2 and DL1 allow the door D to be opened by performing a release operation. Further, the control device performs opening drive control of the electric door opening / closing device PSD based on the opening signal of the inside handle sensor SW1.

(When the outside handle OH is operated with the door D in the fully closed position and the state shown in FIG. 6)
In the state shown in FIG. 6, when the outside handle OH is opened, the opening operation is transmitted to the first outside lever 7 via the operating force transmission member 63. The first outside lever 7 performs a release operation counterclockwise about the shaft 23 and transmits the release operation to the second outside lever 10 via the connecting rod 53, and the detection unit 7 c has an outside handle. It contacts the sensor SW3.
In this case, the release operation of the second outside lever 10 is not transmitted to the release lever 12 because the engagement pin 33 of the lock mechanism is in the lock position. Therefore, unless communication is established between the portable key and the ECU, the fully-closed door latch devices DL2 and DL1 cannot be released and the door D cannot be opened.
Further, the control device does not execute the drive control of the release actuator AC2 and the open drive control of the electric door opening / closing device PSD even when an open signal is transmitted from the outside handle detection sensor SW3, but between the portable key and the ECU. If communication is established, even if the lock mechanism is in the locked state, an open signal from the outside handle detection sensor SW3 is input to the control device, so that the lock actuator AC1 is unlocked and controlled. After switching to the unlocked state, the actuator for release AC2 is driven and controlled to open the electric door opening and closing device PSD.
(When the door D is fully closed and the inside handle IH is opened in the state shown in FIG. 6)
In the state shown in FIG. 6, when the inside handle IH is opened, the opening operation is transmitted to the inside lever 3 via the inside handle shaft 22. As a result, the inside lever 3 is released clockwise from the neutral position around the inside handle shaft 22 against the urging force of the spring 20, and the release operation is opened via the bent portion 3 b. To the inside handle sensor SW1 via the contact portion 3c and the inside handle detection lever 17. The child lock lever 4 and the switch lever 5 are supported so as to be relatively rotatable with respect to the inside handle shaft 22, and therefore are not interlocked with the rotation of the inside handle shaft 22 accompanying the operation of the inside handle IH.

  The opening inside lever 8 is released counterclockwise around the shaft 24 against the urging force of the spring 35. The release operation is transmitted to the engagement pin 18, the sub lever 11, and the emergency lever 9, but is not transmitted to the release lever 12 because the engagement pin 33 of the lock mechanism is in the lock position. In this state, the forward movement of the engagement pin 18 accompanying the release operation of the opening inside lever 8 is not transmitted to the switch lever 5.

  Thereby, even if the opening operation of the inside handle IH is performed, the fully closed door latch devices DL2 and DL1 cannot be released, and the door D cannot be opened. In this case, the control device does not execute the opening drive control of the electric door opening / closing device PSD even when a signal is transmitted from the inside handle sensor SW1.

(When the outside handle OH is operated in the state shown in FIG. 7 with the door D in the fully closed position)
In the state shown in FIG. 7, when the outside handle OH is opened, the opening operation is transmitted to the first outside lever 7 via the operating force transmission member 63. As a result, as in the case where the child mechanism is in the unlocked state, the release operation of the first outside lever 7 is performed by the connecting rod 53, the second outside lever 10, the sub lever 11, the engagement pin 33, the release lever 12, and It is transmitted to the fully-closed door latch devices DL2 and DL1 via the operating force transmission member 64. As a result, the fully-closed door latch devices DL2 and DL1 can open the door D by performing a release operation, and the control device drives the electric door opening and closing device PSD to open based on the open signal of the outside handle detection sensor SW3. Take control.

(When the door D is fully closed and the inside handle IH is opened in the state shown in FIG. 7)
In the state shown in FIG. 7, when the inside handle IH is opened, the opening operation is transmitted to the inside lever 3 via the inside handle shaft 22. As shown in FIG. 9, the inside lever 3 is released from the neutral position about the inside handle shaft 22 in the clockwise direction against the biasing force of the spring 20, and the release operation is opened via the bent portion 3b. Is transmitted to the inside lever 8. In this case as well, the child lock lever 4 and the switch lever 5 are supported so as to be relatively rotatable with respect to the inside handle shaft 22, and therefore do not interlock with the rotation of the inside handle shaft 22 accompanying the operation of the inside handle IH. .

  However, in this child lock state, as shown in FIG. 9, the engagement pin 18 cannot contact the contact portion 11 a of the sub lever 11, but can contact the contact portion 5 b of the switch lever 5. Since the slider 19 is in a locked position where the slider 19 is in a locked position where the abutting portion 19b cannot abut the upper end portion 17a of the inside handle detection lever 17, the engaging pin associated with the release operation of the opening inside lever 8 The forward movement of 18 is not transmitted to the sub lever 11 but is transmitted to the switch lever 5.

  As a result, as shown in FIG. 9, when the switch lever 5 rotates about the inside handle shaft 22 by a predetermined angle in the counterclockwise direction with respect to the inside handle shaft 22, the detection portion 5 b of the switch lever 5 becomes a child. Contact the sensor SW2. As a result, the child sensor SW2 is switched from off to on. Based on the transmission of the ON signal from the child sensor SW2, the control device controls the opening drive control of the electric door opening / closing device PSD to an inexecutable state.

(When the door D is fully opened and the inside handle IH is closed in the state shown in FIG. 4)
When the inside handle IH is closed in the state shown in FIG. 4, the closing operation is transmitted to the inside lever 3 via the inside handle shaft 22. As shown in FIG. 10, the inside lever 3 releases the counterclockwise direction from the neutral position around the inside handle shaft 22 against the urging force of the spring 30, and transmits the releasing operation to the opening inside lever 8. Instead, it is transmitted to the closing inside lever 13. Therefore, in this child lock state, even when the inside handle IH is closed, the closing operation is not transmitted to the switch lever 5.

  When the closing inside lever 13 is released from the initial position in the clockwise direction against the urging force of the spring 31, the releasing operation is transmitted to the fully-open door latch device DL3 via the operating force transmission member 61. As a result, the fully open door latch device DL3 performs a release operation, disengages from the striker, and enables the door D to be closed.

  Further, the inside handle sensor SW1 detects the inside handle when the inside lever 3 closes counterclockwise so that the contact portion 3c of the inside lever 3 comes into contact with the upper end portion 17a of the inside handle detection lever 17 from the front side. The lever 17 is rotated clockwise from the neutral position. Thereby, the inside handle sensor SW1 is switched from off to on. The control device performs the closing drive control of the electric door opening / closing device PSD based on the transmission of the ON signal from the inside handle sensor SW1.

(When the door D is fully opened and the inside handle IH is closed in the state shown in FIG. 7)
When the inside handle IH is closed in the state shown in FIG. 7, the closing operation is transmitted to the inside lever 3 via the inside handle shaft 22. As shown in FIG. 11, the inside lever 3 releases the counterclockwise direction from the neutral position around the inside handle shaft 22 against the biasing force of the spring 30, and transmits the releasing operation to the opening inside lever 8. Instead, it is transmitted to the closing inside lever 13.

  When the closing inside lever 13 is released from the initial position in the clockwise direction against the urging force of the spring 31, the releasing operation is transmitted to the fully-open door latch device DL3 via the operating force transmission member 61. As a result, the fully open door latch device DL3 performs a release operation, disengages from the striker, and enables the door D to be closed.

  Further, the inside handle sensor SW1 is configured such that the inside lever 3 closes counterclockwise so that the contact portion 3c of the inside lever 3 is the upper end of the inside handle detection lever 17 even when the slider 19 is in the child lock position. The inner handle detection lever 17 is rotated from the neutral position in the clockwise direction by coming into contact with 17a from the front side. Thereby, the inside handle sensor SW1 is switched from OFF to ON, and the control device performs the closing drive control of the electric door opening / closing device PSD based on the transmission of the ON signal from the inside handle sensor SW1.

  As described above, since the child lock lever 4 is supported on the inside handle shaft 22 so as to be relatively rotatable, the number of levers pivoted on the shaft 24 can be reduced as compared with the prior art. The apparatus can be made thin. Further, by supporting the switch lever 5 on the inside handle shaft 22 so as to be relatively rotatable, it is possible to further promote the thinning of the apparatus.
