Reference numeral 5 denotes the slide door 2 driven by a motor.
Is a power slide device that slides in a door closing direction and a door opening direction, and is provided inside a quarter panel (outer panel) 6 of the vehicle body 1. Power slide device 5
Is provided with a reversible motor 7 and a wire drum 8 rotated by the power of the motor 7.
And the sliding door 2 are connected by a wire cable 9, and the rotation of the wire drum 8 causes the wire cable 9 to rotate.
Is pulled in either direction, the sliding door 2 slides in the closing direction or the opening direction.

FIGS. 2 and 3 show a cross section of the wire drum 8. The wire drum 8 is provided between a base plate 10 of the power slide device 5 and a cover plate 11 fixed to the base plate 10 at a predetermined interval. Are supported by a drum shaft 12. The wire drum 8 is formed in a cylindrical shape having one closed side and the other open side,
The wire groove 1 with which the cable 9 is engaged is formed on the outer peripheral surface.
3 is formed. A relatively large internal space 14 is formed inside the wire drum 8, and a connection state in which the output of the motor 7 is transmitted to the wire drum 8 in the internal space 14;
The clutch mechanism 15 that switches to a non-connected state in which the rotation of the wire drum 8 is not transmitted to the motor 7 is substantially housed.

The motor 7 is provided at the end of the drum shaft 12.
A drive gear 16 that rotates by the rotation of the drive gear 16 and a rotating disk 17 that rotates integrally with the drive gear 16 are rotatably supported. Since the drive gear 16 and the rotary disk 17 rotate integrally, the rotary disk 1 in FIG. 3 (and FIG. 6) is used.
The figure is simplified by showing only 7. The drum shaft 1
A sleeve 18 is attached to a part of the outer circumference of
8, a spring support 19 is rotatably mounted on the outer periphery of the spring support 19, and a guide plate 20 is rotatably mounted on the outer circumference of the spring support 19, between the guide plate 20 and the annular flange 21 of the spring support 19. A spring 22 is provided. The spring 22 is provided for the purpose of giving the guide plate 20 some rotational resistance.

A pair of oscillating arms 23 and 24 are rotatably mounted on the rotating disk 17 by mounting shafts 25 and 26, and extend to the distal ends of the oscillating arms 23 and 24 in parallel with the drum shaft 12. Slide pins 27 and 28 are provided, respectively. The guide plate 20 has a pair of guide slots 29 in which slide pins 27 and 28 of the swing arms 23 and 24 are slidably engaged, respectively.
30 are formed. The guide slots 29, 30 are shown in FIG.
, And arc-shaped slots 31 and 32 centered on the drum shaft 12 and extension slots 33 and 34 connected to the ends of the arc slots 31 and 32 and extending away from the drum shaft 12. , Extension slots 33, 34
Are formed at the leading end of the shaft and engaging slots 35 and 36 having an arc shape centered on the drum shaft 12.

The inner surface (inner wall) of the wire drum 8 has a plurality of projections 3 projecting toward the drum shaft 12.
7 are formed on the swing arms 23 and 24, respectively. Clutch claws 38 and 39 are formed on the swing arms 23 and 24 so as to be able to engage with the convex portions 37 when the swing arms 23 and 24 swing.

As will be described later in detail, when the power slide device 5 is not operated, the rotating disk 17 and the guide plate 20 are at the positions shown in FIG. In this position, the swing arms 23, 2
4 are engaged with the arc slots 31 and 32, respectively, so that the swing arm 2
The clutch claws 38, 39 of 3, 24 are connected to the wire drum 8
And is disengaged from the convex portion 37. When both the clutch claws 38 and 39 are separated from the projection 37 in this manner, the clutch mechanism 15 is in the non-coupled state, and the rotation of the wire drum 8 is controlled by the motor 7.
Therefore, the wire drum 8 can be rotated with a light force. Accordingly, when the slide door 2 is manually slid, little extra resistance is applied.

When the drive gear 16 and the rotary disk 17 are rotated clockwise by the power of the motor 7 in the state shown in FIG. 3, the swing arms 23 and 24 connected to the rotary disk 17 by the mounting shafts 25 and 26 are also rotated. After rotating clockwise around the drum shaft 12, the slide pin 27 of the swing arm 23 slides in the arc slot 31 of the guide plate 20 and enters the extension slot 33. At this time, since rotation resistance is given to the guide plate 20 by contact with the spring 22, the guide plate 20 does not rotate at this stage.
When the slide pin 27 enters the extension slot 33, the slide pin 27 gradually separates from the drum shaft 12, so that the swing arm 23 swings outward around the mounting shaft 25 as shown by the arrow A. When the slide pin 27 reaches the engagement slot 35, the clutch claw 38 of the swing arm 23 is moved.
Protrudes outward, and as shown in FIG.
With the convex portion 37 of. On the other hand, the slide pin 28 of another swing arm 24 also moves in the guide slot 30,
Since the slide pin 28 moves only in the arc slot 32 centered on the drum shaft 12, the swing arm 24 does not swing around the mounting shaft 26. Does not engage.

When the rotary disk 17 further rotates clockwise with the power of the motor 7 in the state shown in FIG. 6, the power of the motor 7 is transmitted to the wire drum 8 through the engagement between the clutch pawl 38 and the convex portion 37, and 8 also rotates clockwise, the wire cable 9 is pulled in either direction, and the sliding door 2
Slides in the closing or opening direction. Thus, when the clutch pawl 38 is engaged with the projection 37, the clutch mechanism 15 is in the connected state (first connected state). Note that the guide plate 20 rotates together with the rotating disk 17 after the slide pin 27 is engaged with the engagement slot 35. In FIG. 3, when the rotating disk 17 is rotated counterclockwise by the power of the motor 7, the clutch pawls 39 of the other swing arm 24 are engaged with the convex portions 37, and the clutch mechanism 15 is in the connected state. (Second connected state)
And the wire drum 8 also rotates counterclockwise.

The clutch mechanism 15 of the present invention is configured to return from the connected state to the unconnected state by rotating the motor 7 in the reverse direction for a predetermined time (a predetermined amount) before stopping the motor 7. Have been. That is, when the rotating disk 17 is rotated clockwise to the state shown in FIG. 6, the rotating disk 17 is rotated counterclockwise by a predetermined amount, and then the rotation of the motor 7 is stopped. This way,
The slide pin 27 of the swing arm 23 is pulled out from the engagement slot 35 by the reverse rotation of the rotary disk 17, reaches the arc slot 31 via the extension slot 33, and rotates the rotary disk 17 by a predetermined amount of reverse rotation. Is completed, the clutch returns to the position shown in FIG.
Returns to the unconnected state.

As described above, in the present invention, the engagement between the slide pins 27 and 28 and the engagement slots 35 and 36 can be released by reversing the motor 7. It cannot be released by applying a rotational force about the mounting shafts 25, 26. That is, in FIG. 6, even if a force in the direction indicated by the arrow A is applied to the swing arm 23, since the engagement slot 35 has an arc shape centered on the drum shaft 12, the swing arm 23 is attached to the mounting shaft 25.
Therefore, the engagement between the slide pin 27 and the engagement slot 35 is maintained, and the clutch mechanism 15 is maintained in the connected state. This configuration has one advantage and one disadvantage over the prior art. An advantage is that runaway due to the weight of the sliding door, which is a problem of the conventional example, can be suppressed, and a disadvantage is that it is difficult to manually release the connection state of the clutch mechanism 15.

In the conventional example, the runaway due to the weight of the slide door due to its own weight occurs when the slide door slides at a speed higher than the rotation speed of the wire drum, and the swing arms 23 and 24 of the present application are used.
Is a phenomenon that occurs because a force corresponding to the direction of releasing the connected state is applied to a part corresponding to. On the other hand, in the present application, as described above, even if a force in the direction indicated by the arrow A is applied to the swing arms 23 and 24, the connection state of the clutch mechanism 15 is not released. For this reason, even if the slide door 2 tries to run away due to its own weight, the rotational resistance of the motor 7 acts as a brake, so that the slide speed of the slide door 2 is maintained at a predetermined value. Even if the power slide device 5 opens and closes the door 2, runaway of the door is suppressed.

Thus, in the present invention, the swing arm 23,
24, the clutch mechanism 15
If the motor 7 breaks down while the clutch mechanism is in the connected state, the clutch remains connected, which hinders the opening and closing of the slide door 2 manually. Will come. Countermeasures against this are shown in FIGS.

FIGS. 7 and 8 show the output gear 4 of the motor 7.
0, a drive gear 16 supported on the drum shaft 12,
An intermediate gear 41 meshing between the output gear 40 and the drive gear 16 is shown, and these gears constitute a reduction mechanism 42 of the motor 7. The intermediate gear 41 is supported by a long shaft 43 fixed to the base plate 10 so as to be movable in the thrust direction of the shaft 43. A large-diameter head 44 is formed at one end of the shaft 43, and the head 44 and the intermediate gear 4
The intermediate gear 41 is held at a position where it meshes with both the output gear 40 and the drive gear 16 by the elastic force of the spring 45.

Reference numeral 46 designates the intermediate gear 41 as the spring 44
Moving in the thrust direction of the shaft 43 against the elasticity of
In addition, the operation knob can rotate the intermediate gear 41 about the shaft 43. In the embodiment, the operation knob 46
The operation knob 46 is attached to the intermediate gear 41 by engaging about two to four claw legs 47 with the engagement holes 48 of the intermediate gear 41. When the operation knob 46 is moved along the thrust direction of the shaft 43, the claw leg 47 and the engagement hole 4 are moved.
8, the intermediate gear 41 is moved to the spring 4 as shown in FIG.
4, the intermediate gear 41 and the output gear 40 of the motor 7 are disengaged from each other.
1 meshes only with the drive gear 16. As described above, when the engagement between the intermediate gear 41 and the output gear 40 is released, the rotational resistance of the motor 7 and the rotational resistance of the reduction mechanism 40 are not applied to the intermediate gear 41. Accordingly, the drive gear 16 can be easily rotated.

Therefore, if the motor 7 breaks down and the clutch mechanism 15 cannot be returned to the non-coupled state by the power of the motor 7 when the clutch mechanism 15 is in the connected state. The engagement between the intermediate gear 41 and the output gear 40 is released by the operation knob 46, and then the intermediate gear 41 is rotated by the operation knob 46,
The drive gear 16 is rotated in a predetermined direction. That is, FIG.
When the motor 7 breaks down in the state described above, when the drive gear 16 and the rotary disk 17 are rotated counterclockwise by the operation knob 46, the swing arm 2 is rotated by the rotation of the rotary disk 17.
The third slide pin 27 exits so as to be pulled out of the engagement slot 35, reaches the arc slot 31 via the extension slot 33, and the clutch mechanism 15 returns to the uncoupled state. When the clutch mechanism 15 returns to the non-coupled state, when the hand is released from the operation knob 46, the intermediate gear 41 returns to the initial position by the elastic force of the spring 45 and meshes with the output gear 40. If the clutch mechanism 15 is disengaged in this way, the slide door 2 can be manually opened and closed even if the motor 7 is continuously unusable, and the minimum function can be secured.

[0021]

When the drive gear 16 and the rotary disk 17 are rotated clockwise by the power of the motor 7 in the state shown in FIG. 3, the swing arms 23 and 24 connected to the rotary disk 17 by the mounting shafts 25 and 26 are also rotated. And the slide pin 27 of the swing arm 23 is
Slides in the arc slot 31 of the
To enter. At this time, the guide plate 20 has the spring 2
The guide plate 20 does not rotate at this stage because rotation resistance is given by contact with the guide plate 20. Slide pin 2
7 enters the extension slot 33, the slide pin 27
Is gradually separated from the drum shaft 12, so that the swing arm 2
3 swings outward around the mounting shaft 25 in the direction of arrow A, and when the slide pin 27 reaches the engagement slot 35, the clutch claw 38 of the swing arm 23 projects outwardly. As shown in FIG. 6, the protrusions 37 of the wire drum 8 are engaged. On the other hand, the slide pin 28 of another swing arm 24 also moves in the guide slot 30, but since the slide pin 28 moves only in the arc slot 32 centered on the drum shaft 12, the swing arm 24 is mounted. It does not swing about the shaft 26, and therefore, the clutch pawl 39 does not engage with the projection 37.

When the rotary disk 17 further rotates clockwise with the power of the motor 7 in the state shown in FIG. 6, the power of the motor 7 is transmitted to the wire drum 8 through the engagement between the clutch pawl 38 and the convex portion 37, and 8 also rotates clockwise, the wire cable 9 is pulled in either direction, and the sliding door 2
Slides in the closing or opening direction.

However, when the slide door 2 is parked on a slope or the like, the slide door 2 is opened or closed, and an external force is applied to the slide door 2 so as to vigorously slide beyond the sliding speed driven by the motor power. There are times. For example, when such an external force acts on the slide door 2 in the state of FIG. 6, the wire drum 8 rotates clockwise at an overspeed. Then, another protrusion 37A located on the counterclockwise rotation side of one of the protrusions 37 with which the clutch claw 38 is engaged abuts on the back side of the clutch claw 38, and the swing arm 2
3, a force in the direction indicated by the arrow A is applied. At this time, in the present invention, since the engagement between the slide pin 27 and the engagement slot 35 is not released by the external force acting on the swing arm 23 in the direction of the arrow A, the swing arm 23 swings. No, and therefore the wire drum 8
Are kept engaged with the rotating disk 17. For this reason, the overspeed external force applied to the slide door 2 is absorbed by the rotational resistance of the motor 7 and the speed reduction mechanism 42, and the slide speed of the slide door 2 is maintained at a predetermined value.

When the sliding door 2 slides to a predetermined position by the motor power, the motor 7 is once rotated in the reverse direction for a predetermined time (a predetermined amount) before the motor 7 is stopped. That is, by rotating the rotating disk 17 clockwise,
When the state is reached, the motor 7 is operated to rotate the rotating disk 17 counterclockwise by a predetermined amount, and then the rotation of the motor 7 is stopped. By doing so, the slide pin 27 of the swing arm 23 is pulled out from the engagement slot 35 by the counterclockwise rotation of the rotating disk 17, reaches the arc slot 31 via the extension slot 33, and rotates. When the predetermined amount of counterclockwise rotation of the disk 17 ends, the disk 17 returns to the position shown in FIG. 3 and the clutch mechanism 15 returns to the non-coupled state.

If the motor 7 fails and the clutch mechanism 15 cannot be returned to the non-coupled state by the power of the motor 7 when the clutch mechanism 15 is in the connected state, the operation is started. The engagement between the intermediate gear 41 and the output gear 40 is released by the knob 46, and then the intermediate gear 41 is rotated by the operation knob 46, and the drive gear 16
Is rotated in a predetermined direction. That is, in the state of FIG. 6, when the motor 7 breaks down, when the drive gear 16 and the rotating disk 17 are rotated counterclockwise by the operation knob 46, the rotation pin 17 rotates the slide pin 27 of the swing arm 23. It comes out so as to be pulled out from the engagement slot 35 and passes through the extension slot 33 to form the arc slot 3.
Upon reaching 1, the clutch mechanism 15 returns to the non-coupled state. When the clutch mechanism 15 returns to the non-coupled state, when the hand is released from the operation knob 46, the intermediate gear 41 returns to the initial position by the elastic force of the spring 45 and meshes with the output gear 40. By disengaging the clutch mechanism 15 in this manner,
Even if the motor 7 cannot be used continuously, the sliding door 2 can be manually opened and closed, and the minimum function can be secured.

[0026]
