An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a metal outer plate which is called a quarter panel on the side rear of a vehicle body 2, 3 denotes a metal inner plate corresponding to the outer plate 1, and 4 denotes a front-rear guide provided on an outer surface of the outer plate 1. Rails 5 are slide doors that open and close by moving back and forth along the guide rails 4, and a bracket 6 that is slidably engaged with the guide rails 4 is pivotally supported at the rear end of the slide door 5.

Reference numeral 7 denotes a power slide unit for sliding the slide door 5 in the front-rear direction, which is shown in FIG. It is provided in a space between the plates 3. The power slide unit 7 includes an electric motor 8 and a wire drum 10 connected to the motor 8 via a speed reduction mechanism 9 and the like. The wire drum 10 locks one ends 13 and 14 of a pair of wires 11 and 12 (see FIG. 3), and the other ends 15 and 16 of the wires 11 and 12
And protrudes out of the vehicle through the openings 97 and 98 of the vehicle and is locked to the bracket 6. Reference numeral 17 denotes a pulley around which the wires 11 and 12 are wound. Note that a guide rail or the like may be used instead of the pulley 17.

When the wire drum 10 is turned to the left by the motor 8 at the open position, the wire 11 on the front side is
When the rear wire 12 is pulled out by the same length, the sliding door 5 slides in the closing direction (forward) and closes the entrance 18. When the wire drum 10 is rotated to the right by the motor 8 on the same principle, the sliding door 5 slides in the opening direction (rearward).

FIGS. 2 and 3 show the wire drum 10.
The wire drum 10 is supported by a drum shaft 21 between the base plate 19 and the cover plate 20 of the power slide unit 7. The wire drum 10 is formed in a cylindrical shape with one side closed, and a plurality of wire grooves 88 around which the wires 11 and 12 are wound are formed on the outer peripheral surface thereof, and a relatively large space 2 is formed inside.
2 are formed. A power transmission mechanism 23 with a clutch mechanism for transmitting the power of the motor 8 to the wire drum 10 is housed in the space 22.

Reference numeral 24 denotes a gear meshing with the final gear of the speed reduction mechanism 9; 25, a reinforcing plate; and 26, a rotating plate. These three are integrally connected to each other by a connecting pin 27, and are connected to the drum shaft 21. It is rotatably supported.

A pair of swing arms 28 and 29 are rotatably supported on the rotating plate 26 by pins 30 and 31. Reference numeral 32 denotes a guide plate provided so as to overlap the swing arms 28 and 29, and is supported by the drum shaft 21. The swing arm 2 is provided on the guide plate 32.
A pair of guide slots 35 and 36 are formed in which the engagement pins 33 and 34 provided on the respective rotation end sides 8 and 29 are inserted and engaged. As shown in FIG. 3, the guide slots 35 and 36 have arc slots 37 and 38 centered on the drum shaft 21, and an extrusion slot 39 provided at an end of the arc slots 37 and 38 and extending in a direction away from the drum shaft 21. , 40.

A drum inner 41 having excellent wear resistance and impact resistance is mounted on the inner surface of the space 22 of the wire drum 10. In the drum inner 41,
As shown in FIG. 3, a plurality of engaging projections 42 bulging toward the drum shaft 21 are formed. The number of the engagement protrusions 42 is arbitrary, but when the number is increased, the manual clutch release operation described in the section of “0019” is facilitated, so that the number may be 4 to 6 or more. (See FIG. 12).

Reference numeral 43 denotes an inner sleeve provided on the outer periphery of the drum shaft 21, and reference numeral 44 denotes an outer sleeve provided outside the inner sleeve 43. A flange 4 is provided on the inner end of the outer sleeve 44.
5, the flange 45 and the guide plate 32
Is provided between the guide plate 32 and the outer sleeve 44 (drum shaft 2).
A frictional resistance is given between 1) and 1).

When the motor 8 is off, the rotary plate 26 is set so as to be at the position shown in FIG. 3 with respect to the guide plate 32 (in this regard, "001").
6 ”and“ 0017 ”), the engaging pins 3 of the swing arms 28 and 29 supported by the rotating plate 26.
3, 34 are located at the ends of the arc slots 37, 38, respectively, facing the extrusion slots 39, 40. In the state of FIG. 3, the clutch of the power transmission mechanism 23 is disengaged, and the wire drum 10 and the motor 8 are disconnected.

In the state of FIG. 3, for example, when the rotating plate 26 is rotated rightward by the power of the motor 8, the pins 30, 3
The swing arms 28 and 29 connected by 1 also rotate interlockingly.
Then, since the engaging pin 33 of the swing arm 28 moves from the arc slot 37 into the extrusion slot 39, the swing arm 28 swings about the pin 30 in a direction away from the drum shaft 21 and the swing arm The 28 clutch claws 47 are engaged with the engagement projections 42 (see FIG. 8). On the other hand, the swing arm 29
Does not swing around the pin 31 because the engaging pin 34 only moves in the arc slot 38 about the drum shaft 21. Conversely, when the rotary plate 26 is rotated to the left by the power of the motor 8, the swing arm 29 swings in a direction away from the drum shaft 21, and the clutch claws 48 of the swing arm 29 engage with the engagement protrusions 42. But the swing arm 2
8 does not swing. When the rotating plate 26 is rotated in any direction by the motor 8 in this manner, the clutch claws 47, 48 of one of the swing arms 28, 29 abut and engage with the engaging projections 42. As a result, the clutch mechanism is turned on, and the rotation of the rotary plate 26 is mechanically transmitted to the wire drum 10. The guide plate 32 does not rotate due to friction when the engagement pins 33 and 34 move in the guide slots 35 and 36 due to the rotational resistance given by the spring 46.

As described above, when the motor 8 is rotated, the clutch is connected and the wire drum 10 rotates.
When the motor 8 is stopped as it is, the clutch is “engaged”.
And the operation of the slide door 5 by manual operation is hindered. This will be described in detail. For example, when the motor 8 is opened and the clutch claw 47 of the swing arm 28 is engaged with the engagement protrusion 42 of the wire drum 10, the motor 8 stops (see FIG. 8). State), the wire drum 10 can turn to the right, but cannot turn to the left due to the engagement between the clutch pawl 47 and the engaging projection 42. The inability of the wire drum 10 to turn to the left means that the sliding door 5 cannot be manually moved in the closing direction. In order to avoid such a state, according to the present invention, when the motor 8 is stopped, the motor 8 is once rotated in a direction opposite to the previous rotation for a predetermined time (a predetermined amount) to release the clutch. It is. That is, when the motor 8 is rotated to open the door and the state shown in FIG. 8 is reached, the motor 8 is rotated by a predetermined amount in the direction of closing the door opposite to that before and then stopped. When the motor 8 is closed, the rotation plate 26 is turned to the left from the state shown in FIG. 8 by the closing rotation of the motor 8, the clutch pawl 47 of the swing arm 28 is moved away from the engagement projection 42, and the swing arm Since the engaging pin 33 moves inside the pushing slot 39 of the guide slot 35 toward the arc slot 37, the swing arm 28
Swings around the pin 30 in the direction approaching the drum shaft 21 and returns to the state of FIG. 3 when the rotation of the motor 8 by a predetermined amount is completed, and the connection between the wire drum 10 and the motor 8 is disconnected (clutch). After that, the wire drum 10 is restored to a state where it can rotate in any direction. Conversely,
When the door is closed by the motor 8, the motor 8 is rotated by a predetermined amount in the opening direction opposite to that before the motor 8 is stopped.

In the present invention, the state shown in FIG. 3 is an initial state in which the clutch is disengaged. As described above, when the motor 8 is stopped, the swing arms 28, 2
9 is returned to the state shown in FIG. 3, so that another power or a return spring for disengaging the clutch is not required.

As described above, a relatively wide space 22 is formed inside the wire drum 10, and this space 2
2, a power transmission mechanism 23 with a clutch mechanism from a gear 24 meshing with the reduction mechanism 9 to swing arms 28 and 29 abutting and engaging with the inner peripheral surface of the wire drum 10 (drum inner 41). Are substantially stored. For this reason, the whole structure becomes thin, and the installation place of the power slide unit 7 can be set relatively freely.

Reference numeral 49 denotes a cancel surface formed on the swing arm 28, and reference numeral 50 denotes a cancel surface formed on the swing arm 29. As described above, in the present application, when the motor 8 is stopped, the clutch is disengaged by rotating the motor 8 by a predetermined amount in a direction opposite to the previous rotation direction. When the motor 8 fails, the clutch cannot be disengaged by the power (motor 8). In such a case, the sliding door 5 is slightly moved manually in the movable direction, that is, in the opening direction in the state of FIG. Then, the wire 1 is moved by the rearward movement of the slide door 5.
8, the wire drum 10 turns rightward from the state shown in FIG. At this time, since the outer sleeve 44 does not rotate, the guide plate 32 does not rotate.
0 turns right alone. In the embodiment of FIG. 8, when the wire drum 10 rotates about half a clockwise direction, another engaging projection 42 contacts the cancel surface 49 of the swing arm 28 as shown in FIG. When turned, the engaging projection 42
The swing arm 28 swings around the pin 30 in the direction approaching the drum shaft 21 by the contact between the swing arm 28 and the cancel surface 49, the engaging pin 33 returns into the arc slot 37 of the guide slot 35, and the clutch is disconnected. Is done. Conversely, when the motor 8 fails during the closing rotation, the sliding door 5 may be slid in the closing direction. That is, when the motor 8 fails during the rotation of the door opening, the clutch is disengaged by manually moving the sliding door 5 in the opening direction, and when the motor 8 fails during the rotation of the closing door, the sliding door 5 is manually moved in the closing direction. When the number of the engaging protrusions 42 of the wire drum 10 is increased as shown in FIG. 12, the rotation amount of the wire drum 10 until another engaging protrusion 42 contacts the cancel surface 49 of the swing arm 28. And the work becomes easier.

When a metal ring 51 is fitted to the outer end of the outer sleeve 44 and the metal ring 51 is rotated using a tool such as pliers, the guide plate 32 is moved through the outer sleeve 44 and a spring 46. It is configured to be able to rotate. The reason why the guide plate 32 is rotated by the outer sleeve 44 is to assume a situation in which the motor 8 breaks down as soon as the slide door 5 reaches the fully closed position or the fully opened position. That is, when the motor 8 failed during the sliding of the sliding door 5, the clutch could be disengaged by manually sliding the sliding door 5 in the moving direction of the immediately preceding motor 8 as shown in the preceding column. If the motor 8 fails in the fully closed position or the fully opened position, the sliding door 5 hardly moves in the immediately preceding moving direction, so that the clutch cannot be disengaged by the same means as in the preceding column.

Therefore, according to the present invention, when the motor 8 breaks down and the clutch cannot be disengaged at the fully closed position or the fully opened position, the metal ring 51 fixed to the outer end of the outer sleeve 44 is used with pliers or the like. To rotate the guide plate 32 via the outer sleeve 44 and the spring 46. For example, when the wire drum 10 is turned to the right by the motor 8 and the slide door 5 reaches the fully opened position, and the motor 8 breaks down, the clutch mechanism of the present invention is in the state shown in FIG. Since the clutch pawl 47 is engaged with the engaging projection 42, the guide plate 32 is turned clockwise by the metal ring 51. Then, the engagement pin 33 of the swing arm 28 is
When the engagement pin 33 is gradually moved toward the drum shaft 10 by the engagement with the engagement shaft 5 and the engagement pin 33 is engaged with the arc slot 37,
The state shown in FIG. 3 is restored, whereby the clutch is disengaged. When rotating the metal ring 51, the wire 11,
The work becomes easier when the tension of 12 is loosened. If the clutch cannot be disengaged when the sliding door 5 is in the closed position, the guide plate 32 may be turned counterclockwise.

Reference numeral 52 denotes a wire tension roller supported between the base plate 19 and the cover plate 20 by a tension shaft 53. The wire tension roller 52 has a wire 11 wound around the wire drum 10.
Alternatively, one of the wires 12 is looped. Both ends of the tension shaft 53 are slidable in long holes 54 and 55 in the radial direction of the drum shaft 21 formed on the base plate 19 and the cover plate 20, and the tension shaft 53 is slid with respect to the long holes 54 and 55. To adjust the slack of the wire. 56 is a washer fixed to the end of the tension shaft 53.

FIG. 4 shows a mechanism for adjusting the tension pressure of the wire by moving the tension shaft 53 far and near with respect to the drum shaft 21. 57 is two links 5
The support rod 57 is formed with the both ends of the tension shaft 53 so as to be freely rotatable only on the distal end side of the support rod 57. The base end of the support rod 57 is pivotally supported on a movable rod 59 by a shaft 60. The moving rod 59 is formed to be long in the length direction of the long holes 54 and 55, that is, in the direction orthogonal to the sliding direction of the tension shaft 53, and both ends of the moving rod 59 are slidable in the length direction. Are plates 19, 2
0 is attached to a pin 61 by a pin 61.

Reference numeral 62 denotes a pinion gear for sliding the moving rod 59.
It is pivoted between. The pinion gear 62 meshes with a rack 64 formed at the end of the moving rod 59. When the shaft 63 is rotated using a driver or the like, the pinion gear 62 is rotated.
Rotates and the moving rod 59 slides. The shaft 60 in FIG. 4 is at the position closest to the long hole 55, and when the moving rod 59 is slid in this state, the shaft 60 gradually separates from the long hole 55, and therefore, the distance from the shaft 60 is supported. The tension shaft 53 (wire tension roller 52) fixed by the rod 57 moves the drum shaft 21 inside the long holes 54 and 55.
From the wire 1
The slack of 1 and 12 is adjusted. 65 is a pinion gear 62
A ratchet 66 is formed integrally with the ratchet wheel 66. The ratchet 66 meshes with the ratchet wheel 65 to prevent the pinion gear 62 from rotating in reverse.

FIGS. 10 to 12 show a power slide unit 7a according to a second embodiment. In this example,
Means for manually releasing the clutch and a mechanism for adjusting the wire tension pressure have been changed. This will be described below.

In the first embodiment, when the motor 8 fails and the clutch cannot be released at the fully closed position or the fully opened position, the guide plate 32 is rotated via the outer sleeve 44 and the spring 46 to disengage the clutch. However, this structure is complicated because the guide plate 32 is provided in the space 22 of the wire drum 10. Therefore, in the second embodiment, the clutch is released by rotating the wire drum 10a. That is, the release of the clutch by manual sliding of the slide door 5 described in the section of “0019” is performed by manually sliding the slide door 5 in order to rotate the wire drum 10. The wire drum 10a without moving the sliding door 5
Can be rotated to enable manual release of the clutch in the fully closed position or the fully opened position. In order to rotate the wire drum 10a without moving the slide door 5, it is only necessary to loosen the tension of the wires 11, 12. When the tension is released, the wire drum 10a can rotate even if the slide door 5 does not move as much as the tension is released. Specifically, as shown in FIG. 11 and FIG.
A tooth part 90 is formed integrally with a, and the tooth part 90 is meshed with a cancel gear 92 fixed to a cancel shaft 91. One end of the cancel shaft 91 protrudes outward through the base plate 19a, and when the protruding end is rotated using a driver or the like, the wire drum 1
0a rotates manually.

In the second embodiment, a member corresponding to the outer sleeve 44 of the first embodiment becomes unnecessary. The spring 4

The tension adjusting mechanism of the second embodiment is provided for each of the wires 11 and 12. FIG. 13, FIG.
In 4, reference numeral 93 denotes a slide member provided between the base plate 19 a and the cover plate 20 a, and a tension roller 52 a is supported by a tension shaft 53 a inside one end of the slide member. The slide member 93 is provided with four engagement pins 94, and the engagement pins 94 are formed in the long holes 54 formed in the plates 19a and 20a.
a and 55a are slidably engaged with each other. A tension spring 96 is provided between the other end of the slide member 93 and the immovable member 95 fixed to the plates 19a, 20a. As shown in FIG.
The wires 11 and 12 wound around 2a are bent at substantially right angles, and the tension roller 52a is configured to slide in a direction parallel to one of the wires 11 and 12 bent at right angles.

As shown in FIG.
As shown in FIG. 3, the wire shell 99 is covered. The wire shell 99 is flexible but does not expand and contract, and is provided between the power slide unit 7a and the openings 97 and 98 of the outer plate 1 shown in FIG. When the wire shell 99 is used, most of the pulleys 17 become unnecessary. One end of the wire shell 99 is engaged with the shell holder 100 as shown in FIGS. The other end of the wire shell 99 is not shown, but the opening 9
7 and 98 are engaged with a shell holder provided near the same. The shell holders 100 are separate from the slide member 93 and are not engaged with each other. The shell holder 100 is provided with an engagement projection 103 that slidably engages with the elongated holes 101 and 102 formed in both the plates 19a and 20a. 1
Reference numeral 04 denotes a rack formed on the shell holder 100, and a pinion gear 105 is meshed with the rack 104. The pinion gear 105 has a plate 19a,
When the shaft 106 is rotated using a driver or the like, the pinion gear 105 rotates and the shell holder 100 slides. 107 is a ratchet wheel integrally formed with the pinion gear 105, and 108 is a ratchet wheel 107.
A ratchet 109 meshes with the pinion 105 to prevent the pinion gear 105 from rotating in reverse. A spring 109 biases the ratchet.

The shell holder 100 and the opening 9 of the outer plate 1
The length of the wire shell 99 between the wire shells 7 and 98 is always kept constant because the wire shell 99 is made of a material that does not expand and contract. Therefore, the direction in which the shell holder 100 moves away from the wire drum 10a (FIG. 13). (To the right), the length of the wire between the shell holder 100 and the wire drum 10a becomes longer, so that the overall length of the wire is longer, and the wires 11, 12 are in a tensioned state. Becomes Conversely, shell holder 1
00 is closer to the wire drum 10a, the overall length of the wires is shortened, and the wires 11, 12
Will loosen. When assembling the power slide unit 7a, the shell holder 100 is moved closest to the wire drum 10a so that the wire is sufficiently loosened so that the assembly can be easily performed. Perform the initial adjustment of. After the adjustment by the shell holder 100, the tension spring 9
The slack of the wire is absorbed by the tension roller 52a which moves by the elasticity of No. 6.

The first embodiment will be described again. The slide door 5 moved in the door closing direction by the power of the power slide unit 7 can be moved only by the power of the power slide unit 7.
Do not close completely. In other words, the slide door 5 closes to a half-latch state, which is usually called a "half door" with the power of the power slide unit 7, and then reaches a fully latched state, which is a completely closed state, with the power of the automatic opening / closing device. Also,
When the sliding door 5 is opened, when the door latch is released by the power of the manual or automatic opening / closing device, the power sliding unit 7 operates to slide the sliding door 5 in the opening direction.

Since the automatic opening and closing device is not directly related to the gist of the present invention, only the outline will be described with reference to FIGS. The automatic opening / closing device of the present application includes a latch unit 67 which is usually attached to the rear edge of the slide door 5, a power opening unit 68 and a power closing unit 69 which are attached to the internal space of the slide door 5, and a front edge of the slide door 5.

In the closed state, the connector 70 of the sliding door 5 and the connector 82 of the vehicle body 2 are in contact with each other, and when the door opening operation switch is turned on (S005), the flow proceeds to the door opening subroutine (S005).
[0119] After the chime is sounded (S201), the power door unit 68 connected to the battery 83 via the connector 70 and the connector 82 is operated to release the ratchet 73 from the latch 72 and start the timer T4. At the same time, the power supply is performed to the optical sensor unit 84 whose power supply has been stopped in the standby state (S203).

As soon as the ratchet 73 separates from the latch 72, the engagement between the latch 72 and the striker 71 is immediately released by the reaction force of the door seal, and the slide door 5 can be opened. However, after the power door opening unit 68 is operated and before the timer T4 is up (S215), the separation between the connector 70 and the connector 82 is not confirmed (S205), or the engagement between the latch 72 and the striker 71 is stopped. If not canceled (S213), it is something abnormal,
The power supply to the optical sensor unit 84 is stopped (S217),
Further, the operation of the power door unit 68 is stopped (S21
9), restore.

When the slide door 5 is in the openable state without any abnormality, the operation of the power door unit 68 is stopped (S207), and the conditions for automatic door opening by power are checked (S209). If the conditions are satisfied, the motor 8 of the power slide unit 7 is rotated in the door opening direction, the measurement of the pulse signal from the optical sensor unit 84 is started, and the timer T5 is started (S211).

Then, the rotation plate 26 turns right in FIG. 3 via the speed reduction mechanism 9, the gear 24, and the reinforcing plate 25, and the swing arms 28, 29 connected to the rotation plate 26 by the pins 30, 31 turn right. Then, the engagement pin 33 of the swing arm 28 engaged with the guide slot 35 of the guide plate 32 also moves. At this time, since the guide plate 32 is held so as not to rotate together with the rotation resistance of the spring 46, the engaging pin 33 enters the pushing slot 39 of the guide slot 35 from the position of FIG.
The swing arm 28 swings about the pin 30 in a direction away from the drum shaft 21, and the clutch claw 47 of the swing arm 28 is rotated.
Abuts and engages with the engaging protrusion 42 of the wire drum 10.
On the other hand, the swing arm 29 is configured such that the engagement pin 34 is
Since only the guide slot 36 moves within the arc slot 38 centered on the pin 31, it does not swing about the pin 31.

When the clutch pawl 47 and the engaging projection 42 come into contact with each other, the clutch is engaged (see FIG. 8), and the rotation of the rotary plate 26 is directly transmitted to the wire drum 10, and
The wire drum 10 turns right in FIG. Thereby, the wire drum 10 winds up the rear wire 12 and pulls out the front wire 11 by the same amount.
The sliding door 5 slides rearward along the guide rail 4.

While the sliding door 5 is sliding backward, the rotation of the perforated flange 85 of the wire drum 10 is detected by the optical sensor unit 84, and this is output to the control unit 87 as a pulse signal. Calculates the rotation speed (equal to the movement speed of the slide door 5) and the rotation amount (equal to the movement amount of the slide door 5) of the wire drum 10 based on the pulse signal, and monitors the current value of the ammeter 89 ( S221) If the moving speed of the slide door 5 is abnormally low, or if the load current value of the motor 8 is abnormally large, it is considered that some abnormality has occurred.

When the sliding door 5 normally slides backward, before the timer T5 is up (S225), the sliding door 5 rides on a stopper that holds the sliding door 5 in the fully opened position (S223). It is held at the door opening position. Whether or not the sliding door 5 is at the fully opened position can be confirmed by detecting the amount of movement of the sliding door 5 by integrating pulse signals from the optical sensor unit 84, detecting an overcurrent of the motor 8 when passing over the stopper, and the like. When the slide door 5 rides on the stopper, the motor 8 of the power slide unit 7
The motor 8 is rotated in the opposite direction (door closing direction) for a predetermined time (a predetermined amount) by reversing the plus and minus of the power supply to the motor (S227). In addition, when there is an abnormality in the moving speed of the slide door 5 or the load current value of the motor 8, the motor 8 is similarly reversed by a predetermined amount. The overcurrent detection of the motor 8 is detected both in the middle of the slide and in the stepping over the stopper, and it is not possible to distinguish between them. However, since the subsequent control contents are the same, there is no need to substantially distinguish them.

The reason for rotating the motor 8 in the opposite direction for a predetermined time (predetermined amount) is that the clutch engagement state in which the clutch pawl 47 of the swing arm 28 is engaged with the engagement projection 42 is released. That's why. In other words, when the motor 8 is rotated in the opposite direction for a predetermined time (predetermined amount) in the state of FIG. 8, the rotating plate 26 turns to the left, so that the clutch pawl 47 of the swing arm 28 moves away from the engagement projection 42. And the engaging pin 33 of the swing arm 28 is
5 moves toward the arc slot 37 in the extrusion slot 39, whereby the swing arm 28 swings about the pin 30 in the direction approaching the drum shaft 21, and returns to the state of FIG. In this state, the wire drum 10 and the motor 8
The connection with the side is disconnected (clutch is released), and thereafter, the wire drum 10 is restored to a state where it can rotate in any direction.

The case where the motor 8 fails and cannot rotate in the reverse direction will be described. If the motor 8 breaks down while the sliding door 5 is sliding rearward (in the direction of opening the door), the clutch pawl 47 of the swing arm 28 engages with the engaging projection 4.
In this state, it is very difficult to manually slide the slide door 5 forward. In such a case, the slide door 5 is slightly moved manually in a movable direction, that is, backward. Then, the wires 11, 12 are moved by the rearward movement of the slide door 5.
Moves, and the wire drum 10 independently turns rightward from the state of FIG. At this time, since the outer sleeve 44 does not rotate, the guide plate 32 also does not rotate. Wire drum 1
When the wire drum 10 rotates clockwise about half a turn, another engaging projection 42 comes into contact with the cancel surface 49 of the swing arm 28, and when the wire drum 10 further turns right, the engaging projection 42 and the cancel surface 4
The swing arm 28 swings about the pin 30 in the direction approaching the drum shaft 21 by contact with the pin 9, the engaging pin 33 returns to the inside of the arc slot 37 of the guide slot 35, and the clutch is disconnected. Thereby, the sliding door 5 can be slid in any of the front and rear directions thereafter.

When the motor 8 cannot rotate in the reverse direction after the sliding door 5 has been slid backward to the fully opened position, it is difficult to release the clutch in the manner described in the section "0046". That is, since the sliding door 5 in the fully opened position hardly moves backward, the amount by which the wire drum 10 can be manually rotated is extremely reduced, and it is virtually impossible to release the clutch by this method. Become. In such a case, in the first embodiment, the metal ring 51 fixed to the outer end of the outer sleeve 44 is rotated using pliers or the like, whereby the guide plate 32 is moved through the outer sleeve 44 and the spring 46. Turn right at 8. Then, by the rotation of the guide plate 32, the engagement pin 33 of the swing arm 28 moves from the push-out slot 39 of the guide slot 35 toward the arc slot 37, and returns to the state of FIG. 3, and the clutch is disengaged. When rotating the metal ring 51, the work becomes easier if the tension of the wires 11, 12 is loosened. If the clutch cannot be released when the sliding door 5 is in the fully closed position,
The guide plate 32 may be turned counterclockwise.

In the second embodiment, the clutch is disconnected by rotating the wire drum 10a via the cancel gear 92 instead of rotating the metal ring 51. This will be described below. In the state of FIG. 13, the shell holder 100 is
The shell holder 100 is slid to the right by the pinion gear 105, and the shell holder 100 is away from the wire drum 10a, and the bare wire portion between the shell holder 100 and the wire drum 10a is longer. On the other hand, the length of the wire shell 99 between the shell holder 100 and the openings 97 and 98 of the outer plate 1 is constant, and
Since the lengths of the wires 11 and 12 inside the wire are also constant, the length of the wires arranged as a whole is long, and thus the wires are in tension. Therefore, FIG.
At 3, remove the ratchet 108 from the ratchet wheel 107,
The pinion gear 105 is released, and the shell holder 100 is released. Then, since the wires 11 and 12 try to loosen the tension, the shell holder 100 is moved to the left side in FIG. 13 so as to approach the wire drum 10a, and the nakedness between the shell holder 100 and the wire drum 10a is reduced. To shorten the wire section. As a result, the overall length of the wires 11 and 12 is reduced, and the wires are loosened. At this time, the tension roller 52a also slides to the left due to the elasticity of the tension spring 96, but the amount of movement of the tension roller 52a causes the shell holder 10 to move.
If the moving amount of 0 is set to be large, the wire is greatly loosened.

When the wire is loosened as described above, the wire drum 10a can be rotated without moving the slide door 5 by the amount of the loosened wire. Therefore, the cancel shaft 91
Is rotated using a screwdriver or the like, and the cancel gear 9 is rotated.
2 to rotate the wire drum 10a. When the wire drum 10a is rotated in this manner, the same principle as when the slide door 5 is manually moved (“004”) is used.
6)), the clutch can be released. The second
In the embodiment, since the engagement protrusions 42a of the wire drum 10a are formed in large numbers, the clutch can be released with a small rotation amount of the wire drum 10a. After the motor 8 is rotated in the reverse direction to disengage the clutch, the measured number of pulses is reset (S229).

(Door closing action) In the open state, the optical sensor unit 84 is still supplied with power. When the door closing operation switch is turned on (S003), the door closing condition is confirmed (S01).
5) When the condition is satisfied, the process proceeds to the door closing subroutine, a chime is sounded (S101), and the motor 8 of the power slide unit 7 is rotated in the door closing direction (S103). Then, the rotary plate 26 is turned to the left in FIG. 3 via the speed reduction mechanism 9, the gear 24, and the reinforcing plate 25, and the swing arm 29 swings about the pin 31 on the same principle as when the door is opened. The clutch claws 48 of the swing arm 29 are engaged with the engaging projections 42 of the wire drum 10, whereby the wire drum 10 turns left to wind up the front wire 11 and to pull the rear wire 12. Then, the slide door 5 is slid forward along the guide rail 4.
At the same time, the timers T1 and T2 are started, and the measurement of the pulse signal from the optical sensor unit 84 is started (S105).

When the slide door 5 slides normally forward due to the rotation of the wire drum 10, before the timer T1 is up (S109), the slide door 5 gets over the stopper that holds the slide door 5 at the fully open position. (S10
7). The overtravel of the stopper is confirmed by the amount of movement of the slide door 5 by integrating pulse signals. If it is not confirmed that the stopper has been traversed within the time, the motor 8 is rotated in the opposite direction for a predetermined time (predetermined amount) for the purpose of disconnecting the clutch (S111), and the number of pulses is reset (S113) to recover.

When the vehicle has successfully passed the stopper (S107),
The moving speed of the slide door 5 and the load current value of the motor 8 determined based on the pulse signal are monitored (S117). If any of these is abnormal, the timer T3 is started (S141). Until the timer T3 is up (S147) or the door-opening operation switch is turned on (S145), an alarm is sent out, and the process proceeds to step 211 to open the slide door 5.

When the sliding door 5 normally slides forward, the connector 70 of the sliding door 5 contacts the connector 82 of the vehicle body 2 before the timer T2 is up (S121) (S11).
9) Due to this contact, the electric power of the battery 83 is supplied to the power closing unit 69, and the power closing unit 69 becomes operable. The state of movement of the slide door 5 after the contact between the connector 70 and the connector 82 is confirmed by the load current of the motor 8 (S123). Even after the connector 70 and the connector 82 come into contact with each other, the sliding door 5 slides in the closing direction by the power of the motor 8, whereby the latch unit 67 is closed.
The latch 72 rotates by engaging with the striker 71, and the ratchet 73 engages with the half-latch step 74 of the latch 72. The door is closed by the power slide unit 7 until the ratchet 73 engages with the half-latch step 74 of the latch 72, but if the latch 72 rotates greatly at this stage, the ratchet 73 moves to the full-latch step of the latch 72. When the full latch is engaged with the part 75 (S125), the power closing unit 69 does not need to close the door. Therefore, the power supply to the optical sensor unit 84 is stopped (S131), and the clutch is disengaged. Then, the motor 8 is rotated in the opposite direction for a predetermined time (a predetermined amount) (S111), and the number of pulses is reset (S113) to recover.

When only the half latch state is confirmed
(S127), the motor 8 is rotated in the opposite direction for a predetermined time (predetermined amount) for the purpose of disconnecting the clutch (S133), the number of pulses is reset (S135), and the power closing unit 69 is operated.
(S137) The shaft 76 is turned right in FIG. Then, the lever 77 rotates, and the roller 79 moves rightward while being guided by the guide groove 80, and the latch 7 at the half-latch position is moved.
When the latch 72 is rotated toward the full-latch position and the door is fully closed, the closing of the door is completed. Therefore, the power closing unit 69 is stopped, and the power supply to the optical sensor unit 84 is stopped. (S139) Restore.

If the motor 8 breaks down and the clutch cannot be released by the motor 8 while the slide door 5 is sliding forward or in the half latch state or the full latch state, the slide door 5 must be manually slid forward. If the metal ring 51 is rotated by a tool to turn the guide plate 32 to the left or the wire drum 10 is turned to the left, the clutch can be manually released.

(Follow-up control by manual operation)
When the sliding door 5 is manually closed and opened, a mechanism for detecting this operation and performing automatic closing and automatic opening is also provided. First, when the door is open, power is supplied to the optical sensor unit 84. Therefore, when the slide door 5 is manually moved in the closing direction, the optical sensor unit 84 sends out a pulse signal due to the rotation of the wire drum 10. The pulse signal causes the wire drum 10
Is rotating in the door closing direction (S007). Then, the closing condition is confirmed (S021), and when the condition is satisfied,
The process proceeds to the door closing operation following subroutine, after the chime is sounded (S301), the motor 8 of the power slide unit 7 is closed (S303), and the flow proceeds to step 117 to slide the slide door 5 forward.

When the open handle is manually operated in the closed state to release the latch 72 of the latch unit 67 in a known manner, usually, the sliding force is such that the connector 70 and the connector 82 are separated by the reaction force of the door seal. Door 5 opens. The separation between the connector 70 and the connector 82 (S
009) or when the release of the latch 72 (S011) is detected, the control unit 87 starts power supply to the optical sensor unit 84.
(S025). In this state, when the sliding door 5 is further manually slid backward, the optical sensor unit 84 sends out a pulse signal due to the rotation of the wire drum 10, and the pulse signal causes the wire drum 10 to rotate in the door opening direction. Is determined (S027). Then, the control unit 87 determines that the door is manually opened, sounds a chime (S401), and rotates the motor 8 of the power slide unit 7 to open the door (S403). Slide 5 forward.

(Adjustment of Wire Tension Pressure) In the first embodiment, when adjusting the tension pressure of the wires 11 and 12, the pinion gear 62 is rotated by turning the shaft 63 using a screwdriver. Then, the pinion gear 6
The moving rod 59 with which the rack 64 meshes with 2 moves in a direction orthogonal to a straight line connecting the drum shaft 21 and the tension shaft 53, and the shaft 60 gradually moves away from the long hole 55. Therefore, the tension shaft 53 whose distance from the shaft 60 is fixed by the support rod 57 is formed by the elongated holes 54 and 55.
Gradually slides in the direction away from the drum shaft 21,
The slack of the wires 11 and 12 is adjusted. The tension pressure is adjusted in this manner. However, since the moving distance of the tension shaft 53 is shorter than the moving distance of the moving rod 59, the tension pressure can be easily adjusted with a small force.

In the second embodiment, the wires 11, 1
The tension pressure of 2 is divided into an initial adjustment by the shell holder 100 and a subsequent fine adjustment by the tension spring 96. First, when assembling the power slide unit 7a, the shell holder 100 is brought closest to the wire drum 10a so that assembly can be performed easily. Then, the shell holder 100 and the opening 9 of the outer plate 1 are formed.
The length of the wire shell 99 between the shell holder 100 and the wire drum 1 is kept constant because the wire shell 99 is made of a material that does not expand and contract.
The length of the wire as a whole is shortened by an amount corresponding to the short length of the bare wire portion between Oa and the wire, and the wire is in a slack state, so that assembly can be easily performed. After the assembly is completed, when the shaft 106 is rotated by using a driver or the like, the pinion gear 105 is rotated, and the pinion gear 10 is rotated.
The shell holder 100 in which the rack 104 meshes with the shell 5 moves rightward in FIG. 13 and separates from the wire drum 10a. Then, the wire is gradually tensioned because the entire length of the wire becomes longer. Wire 11, 12
Is set to a predetermined tension state, the initial setting ends. After the completion of the initial setting, the slack of the wire is absorbed by the tension roller 52a which moves by the elasticity of the tension spring 96.

[0060]

As described above, the present invention relates to a wire drum that slides on the slide door 5 when the slide door 5 is connected to the slide door 5 slidably mounted on the vehicle body 2 via the wires 11 and 12 and rotates. 10, a motor 8 for rotating the wire drum 10, and a clutch mechanism provided between the motor 8 and the wire drum 10. In the power sliding device for a sliding door, the clutch mechanism includes the motor 8 , The opening swing arm 28 and the closing swing arm 29 held by the rotating plate 26, and the opening swing arm 28 when the motor 8 rotates to open. When the motor 8 is closed with the wire drum 10 and the door is rotated, the swing arm 29 for closing the door is engaged with the wire drum 10. When the motor 8 closes the door drum 10 by a predetermined amount while the opening and closing swing arm 28 is engaged with the wire drum 10, the swinging arm 29 for closing the door is locked before the swing arm 29 is engaged with the wire drum 10. The swing arm 28 for opening the door is disengaged from the engagement with the wire drum 10 and the swing arm 29 for closing the door is
When the motor 8 rotates to open the door by a predetermined amount while engaging with the wire drum 10, the swinging arm 29 for closing the door is moved to the wire drum 10 before the swing arm 28 for opening the door is engaged with the wire drum 10. And a guide plate 32 which is disengaged from the engagement with the wire drum 10 when the swing arm 28 for opening the door or the swing arm 29 for closing the door is engaged with the wire drum 10. When it is rotated in any direction while the door is open, the engagement between the swing arm 28 for opening the door or the swing arm 29 for closing the door and the wire drum 10 is released without substantially sliding the slide door 5. Since the clutch mechanism of the power sliding device for a sliding door is constructed so as to be capable of being driven, the power of a motor 8 for sliding the sliding door 5 causes the clutch mechanism to be engaged. The clutch can be switched even if the slide cannot be disengaged and the slide door 5 cannot be moved by rotating the guide plate 32 in a predetermined direction even when the clutch cannot be disengaged due to the failure of the motor 8. In addition, there is no trouble in opening and closing the slide door 5 manually. The present invention also provides a clutch mechanism for a power sliding device for a sliding door, wherein the guide plate 32 is formed with guide slots 35 and 36 in which the swing arms 28 and 29 are engaged. When the rotary shaft 32 is rotated, the swinging arms 28 and 29 can be reliably returned to the non-engaged position by the guide slots 35 and 36.

Extrusion slot 3
Because the clutch mechanism of the power sliding device for the sliding door is composed of the sliding doors 9 and 40, even if the guide plate 32 is rotated to return one swing arm to the disengaged position, the other swing arm projects to the engaged position. I will not do it. The present invention also provides a wire drum 10a that is connected to a slide door 5 slidably attached to the vehicle body 2 via wires 11 and 12 to slide the slide door 5 when rotated, and a wire drum 10a.

The wire drum 10a is configured to be manually rotatable without sliding the slide door 5 when the wires 11 and 12 are loosened by the tension mechanism, and thus, when the wire drum 10a is manually rotated, the slide door is rotated. Since the clutch mechanism of the power sliding device for a sliding door is configured so that the clutch of the clutch mechanism can be released without sliding the sliding door 5, the on / off switching of the clutch mechanism can be performed by the power of the motor 8 that slides the sliding door 5. The motor 8 breaks down Even when the switch can no longer be canceled,
Even if the slide door 5 cannot be moved if the wire is loosened and the wire drum 10a is rotated in a predetermined direction, the clutch can be manually released even when the slide door 5 cannot be moved, so that there is no problem in opening and closing the slide door 5 manually.

Therefore, the configuration for manually rotating the wire drum 10a is reliable, and the size does not become so large. Further, according to the present invention, in the apparatus, the clutch mechanism projects outward when the motor 8a rotates to open the door and engages with the wire drum 10a when the swing arm 28a for opening and the motor 8a rotate to close the door. A swing arm 29a for closing the door that projects outward and engages with the wire drum 10a, and the wire drum 10a has one swing arm 28a that projects outward when the wire drum 10a is manually rotated. ,
Since the clutch mechanism of the power sliding device for a sliding door is provided with an engaging projection 42a for returning one of the swinging arms 28a, 29a in the anti-projection direction by contacting the swinging arm 29a, the clutch is released by manual rotation of the wire drum 10a.
