Abstract

PROBLEM TO BE SOLVED: To reduce the consumption of a battery, by suspending the electric supply from the battery to an optical sensor detecting an abnormal rotary speed during the sliding motion of the door when a latch unit is in a half-latched or a fully latched state. SOLUTION: A sliding door against a car body is provided with a latch unit brought to a fully latched state through a half-latched state by fitting to a striker fixed to the car body, and a motor 8 driving the sliding door by rotating a wire drum connected to the sliding door through a wire. A controller 87 controling the revolution of the motor 8 suspends the electric power from a battery 83 to an optical sensor 84 detecting the rotary speed of the wire drum when the latch unit is in the half-latched or fully latched state. In this way, electric current is not supplied to the optical sensor 84 having a large dark current in the waiting state in the closed condition of the door. Hence, the burden of the battery 83 is reduced even when a car is parked for a long time.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power slide device for a slide door.

[0002]

2. Description of the Related Art Conventionally, a slide door slidably attached to a vehicle body, and a latch unit provided on the slide door and engaged with a striker fixed to the vehicle body to reach a full latch state via a half latch state When,
A wire drum connected to the slide door via a wire, a motor for rotating the wire drum to slide the slide door in the closing direction and the opening direction, and the motor for rotating the motor to open the door A power slide device for a slide door having a door opening control for opening and sliding the door and a control unit for closing the door by rotating the motor to close and slide the sliding door is known.

[0003]

The slide door having the power slide device as described above is provided with a safety mechanism for immediately stopping the slide when a part of the body or belongings are caught during the slide. It is provided. The conventional safety mechanism is to detect the load of the motor, and it has been considered that pinching occurs when the load becomes abnormally high. There are some problems with such a safety mechanism. The first is that the change in motor load is delayed with respect to the occurrence of an abnormality. Secondly, when the sliding door slides, the sliding resistance becomes high as the sliding door approaches the end, and the motor load also increases accordingly. Therefore, the load value must be set higher. is there. If it is set higher, the response becomes worse. Thirdly, the sliding resistance of the sliding door is considerably different depending on the maintenance condition of the vehicle. Therefore, it is necessary to set a high load value so as to absorb the individual difference. Therefore, the responsiveness becomes worse.

[0004]

In order to overcome the above-mentioned problems, the sliding speed of the sliding door is obtained by measuring the rotating speed of the wire drum with an optical sensor, and when the sliding speed of the sliding door becomes abnormally slow, It may be considered that an abnormality such as entrapment of a foreign substance has occurred, but in this case, it is necessary to take measures against dark current in the optical sensor. Since the photo sensor has a large dark current in the standby state, the battery is burdened when parking for a long period of time. Therefore, in the present invention, when the door is closed, the power supply to the optical sensor is stopped to prevent the battery from being consumed.

[0005]

Therefore, according to the present invention, the sliding door 5 slidably attached to the vehicle body 2 is provided.
And a latch unit 67 which is provided on the slide door 5 and is engaged with a striker 71 fixed to the vehicle body 2 to reach a full latch state through a half latch state, and the slide door 5 through wires 11 and 12.

And an optical sensor 84 capable of detecting the rotation speed of the wire drum 10 and a battery 83, and the controller 8
7 is for stopping or reversing the motor 8 when the rotation speed is abnormal during the sliding of the slide door 5, and the latch unit 67 is half-powered from the battery 83 to the optical sensor 84. This is a power sliding device for a sliding door that is not operated in the latched state or the fully latched state.

[0006]

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

Reference numeral 7 denotes a power slide unit for sliding the slide door 5 in the front-rear direction. In FIG. 1, the power slide unit is shown expanded to the vehicle body 2. It is provided in the space between the plates 3. The power slide unit 7 is provided with 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 is locked with one ends 13 and 14 (see FIG. 3) of the pair of wires 11 and 12, and the other ends 15 and 16 of the wires 11 and 12 are the outer plate 1 respectively.
It is projected to the outside of the vehicle through the openings 97 and 98 and is locked to the bracket 6. Reference numeral 17 is a pulley around which the wires 11 and 12 are wound. A guide rail or the like may be used instead of the pulley 17.

The slide door 5 indicated by the solid line in FIG. 1 is in the open position, and at this position, the slide door 5 is held by the full-open stopper 110 so as not to move carelessly due to inclination of the road surface or the like. The slide door 5 is in the open position and the wire drum 10
When the left side is rotated by the motor 8, the wire 11 on the front side is wound up by the wire drum 10, and the wire 12 on the rear side is pulled out by the same length, so that the slide door 5 passes over the full-open stopper 110 and closes the door. Slide (front) and close the entrance / exit 18. On the same principle, when the wire drum 10 is rotated to the right by the motor 8, the slide door 5 slides in the door opening direction (rear),
Stopping by overcoming the fully open stopper 110. There are various configurations of the full-open stopper 110,
FIG. 1 shows a very simple leaf spring type. The leaf spring type full-open stopper 110 is attached to a lower part of the vehicle body 2 in an inconspicuous place, and when the slide door 5 slides to the open position, a protrusion or a roller (not shown) of the slide door 5 is engaged, As a result, the slide door 5 is held in the open position.

2 and 3 show the wire drum 10
The wire drum 10 is supported by the 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 wide space portion 22 is formed inside. It is 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 is a gear meshing with the final gear of the speed reduction mechanism 9, 25 is a reinforcing plate, and 26 is a rotating plate. These three are integrally connected to each other by a connecting pin 27 and connected to the drum shaft 21. It is rotatably supported.

A pair of swing arms 28 and 29 are rotatably supported on the rotary plate 26 by pins 30 and 31. Reference numeral 32 is 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 attached to the guide plate 32.
A pair of guide slots 35 and 36 into which the engaging pins 33 and 34 provided on the rotating end sides of 8 and 29 are inserted and engaged are formed. As shown in FIG. 3, the guide slots 35 and 36 are arc slots 37 and 38 centered on the drum shaft 21, and an extrusion slot 39 that is connected to the ends of the arc slots 37 and 38 and extends in a direction away from the drum shaft 21. , 40.

A drum inner 41 having excellent wear resistance and impact resistance is attached to 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 protrusions 42 that bulge toward the drum shaft 21 side are formed. The number of the engaging convex portions 42 is arbitrary, but if the number is increased, the work of manually releasing the clutch described in the column of “0019” becomes easy, so that it may be 4 to 6 or more. (See Figure 12).

Reference numeral 43 denotes an inner sleeve provided on the outer circumference of the drum shaft 21, and 44 denotes an outer sleeve provided on the outer side of the inner sleeve 43. The flange 4 is provided on the inner end of the outer sleeve 44.
5, the flange 45 and the guide plate 32 are formed.
A spring 46 is provided between the guide plate 32 and the outer sleeve 44 (drum shaft 2).
Frictional resistance is imparted to 1).

The rotating plate 26 is set so as to be in the position shown in FIG. 3 with respect to the guide plate 32 when the motor 8 is off.
6 "and" 0017 "), the engaging pin 3 of the swing arms 28 and 29 pivotally supported by the rotary plate 26.
Reference numerals 3 and 34 are both end portions of the arcuate slots 37 and 38, and are located so as to face the extrusion slots 39 and 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 side are not connected.

In the state of FIG. 3, for example, when the rotary plate 26 is rotated to the right by the power of the motor 8, the pins 30, 3
The swinging arms 28 and 29 connected by 1 also rotate together.
Then, the engaging pin 33 of the swing arm 28 moves from the arcuate slot 37 into the push-out slot 39, so that the swing arm 28 swings about the pin 30 in the direction away from the drum shaft 21 to swing the swing arm. The clutch claw 47 of 28 engages with the engagement protrusion 42 (see FIG. 8). On the other hand, the swing arm 29
The engaging pin 34 moves only in the arcuate slot 38 centered on the drum shaft 21, so that swinging about the pin 31 does not occur. On the contrary, when the rotary plate 26 is rotated counterclockwise by the power of the motor 8, the swing arm 29 swings in the direction away from the drum shaft 21, and the clutch claw 48 of the swing arm 29 engages with the engagement protrusion 42. But swing arm 2
8 does not rock. In this way, when the rotating plate 26 is rotated in either direction by the motor 8, the clutch claws 47 and 48 of either one of the swing arms 28 and 29 are brought into abutting engagement with the engaging convex portion 42, and As a result, the clutch mechanism is “engaged” 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 rotation resistance imparted by the spring 46.

As described above, when the motor 8 is rotated, the clutch is connected and the wire drum 10 is rotated.
When the motor 8 is stopped as it is, the clutch "engages".
However, the manual operation of the slide door 5 is hindered. This will be described in detail. For example, when the motor 8 is rotated to open the door 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 is stopped (see FIG. 8). In the state), the wire drum 10 can be turned to the right, but due to the engagement of the clutch claw 47 and the engaging protrusion 42, the wire drum 10 cannot be turned to the left. The fact that the wire drum 10 cannot be turned counterclockwise means that the slide door 5 cannot be manually moved in the closing direction. In order to avoid such a state, in the present invention, when the motor 8 is stopped, the motor 8 is once rotated in a direction opposite to the rotation so far for a predetermined time (a predetermined amount) to release the clutch. I am doing it. 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 opposite door closing direction and then stopped. By doing so, the rotation plate 26 rotates counterclockwise from the state shown in FIG. 8 due to the rotation of the closing door of the motor 8, the clutch claw 47 of the swing arm 28 moves in a direction away from the engaging convex portion 42, and the swing arm 28 also moves. The engaging pin 33 of 28 is the push-out slot 39 of the guide slot 35.
Since the inside moves toward the circular arc slot 37, the swing arm 28 swings about the pin 30 in the direction approaching the drum shaft 21, and when the rotation of the motor 8 by a predetermined amount is completed, the state returns to the state of FIG. , The connection between the wire drum 10 and the motor 8 side is disconnected (the clutch is disengaged).
0 returns to a state in which it can rotate in either direction. On the contrary, when the door is closed by the motor 8, the motor 8 is rotated by a predetermined amount in the door opening direction opposite to that before the motor 8 is stopped.

In the present invention, the state shown in FIG. 3 is the initial state in which the clutch is disengaged. As described above, when the motor 8 is stopped, the swing arm 28, 2 is driven by the power of the motor 8.
Since 9 is returned to the state of FIG. 3, another power source for releasing the clutch and a return spring are unnecessary.

As described above, a relatively wide space 22 is formed inside the wire drum 10.
The power transmission mechanism 23 with a clutch mechanism from the gear 24 meshing with the speed reduction mechanism 9 side to the swing arms 28 and 29 that abut and engage with the inner peripheral surface of the wire drum 10 (drum inner 41). Is practically stored. For this reason, the entire structure becomes thin, and the installation location of the power slide unit 7 can be set relatively freely.

Reference numeral 49 is a cancel surface formed on the swing arm 28, and 50 is a cancel surface formed on the swing arm 29. As described above, in the present application, when the motor 8 is stopped, the motor 8 is rotated by a predetermined amount in the opposite direction to the previous rotation to disengage the clutch, but in the unlikely event that the sliding door 5 is sliding. When the motor 8 fails, the power (motor 8) cannot disengage the clutch. In such a case, the slide door 5 is manually moved slightly in the movable direction, that is, in the state of FIG. Then, the wire 1 is moved by the backward movement of the slide door 5.
As the wires 1 and 12 move, the wire drum 10 turns right from the state shown in FIG. At this time, since the outer sleeve 44 does not rotate, the guide plate 32 does not rotate, and the wire drum 1
0 turns right alone. In the embodiment of FIG. 8, when the wire drum 10 rotates about half a rightward direction, another engaging projection 42 abuts on the cancel surface 49 of the swing arm 28 as shown in FIG. 9, and the wire drum 10 moves to the right. When rolled, the engaging protrusion 42
The swing arm 28 swings about the pin 30 toward the drum shaft 21 by the contact between the cancel surface 49 and the cancel surface 49, the engaging pin 33 returns to the inside of the arc slot 37 of the guide slot 35, and the clutch is disengaged. To be done. On the other hand, when the motor 8 breaks down while the door is rotating, the slide door 5 may be slid in the door closing direction. That is, when the motor 8 breaks down while the door is rotating, the sliding door 5 is manually moved in the opening direction, and when the motor 8 is broken during closing, the clutch is released by manually moving it 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 amount of rotation of the wire drum 10 until another engaging protrusion 42 abuts the cancel surface 49 of the swing arm 28. Can be reduced and work becomes easier.

A metal ring 51 is fitted to the outer end of the outer sleeve 44, and when the metal ring 51 is rotated using a tool such as pliers, the guide plate 32 is moved through the outer sleeve 44 and the spring 46. It is constructed so that it can be rotated. The reason why the guide plate 32 is rotated by the outer sleeve 44 is that the motor 8 breaks down as soon as the slide door 5 reaches the completely closed position or the completely opened position. In other words, if the motor 8 breaks down while the sliding door 5 is sliding, the clutch can be disengaged by manually sliding the sliding door 5 as shown in the previous column in the moving direction of the motor 8 immediately before. When the motor 8 fails in the completely closed position or the completely opened position, the sliding door 5 hardly moves in the immediately preceding moving direction, and therefore the clutch cannot be disengaged by the same means as in the previous section.

Therefore, according to the present invention, when the motor 8 fails in the completely closed position or the completely opened position and the clutch cannot be released, 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 rotated to the right by the motor 8 and the slide door 5 reaches the fully open position, and the motor 8 fails, the clutch mechanism of the present application is in the state of FIG. Since the clutch claw 47 is engaged with the engagement protrusion 42, the guide plate 32 is rotated to the right by the metal ring 51. Then, the engaging pin 33 of the swinging arm 28 is engaged with the guide slot 3
When the engagement pin 33 comes into engagement with the arcuate slot 37 by gradually moving toward the drum shaft 10 side by engagement with 5,
The state of FIG. 3 is restored, and the clutch is disengaged. When rotating the metal ring 51, the wire 11,
If the tension of 12 is loosened, the work becomes easier. If the clutch cannot be released when the slide door 5 is in the closed position, the guide plate 32 may be rotated counterclockwise.

Reference numeral 52 is 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, either one of the wires 12 is wound around. Both ends of the tension shaft 53 are slidable in long holes 54 and 55 that are long 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. This adjusts the wire slack. 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
8 is a supporting rod formed together, and both ends of the tension shaft 53 are rotatably supported by the tip end of the supporting rod 57 so as to be rotatable. The base end side of the support rod 57 is pivotally supported on the moving rod 59 by a shaft 60. The movable rod 59 is formed long in the longitudinal direction of the elongated holes 54, 55, that is, in the direction orthogonal to the sliding direction of the tension shaft 53, and the movable rod 59 is slidable in the longitudinal direction at both ends thereof. Plates 19 and 2
0 is attached by a pin 61.

Reference numeral 62 is a pinion gear for sliding the movable rod 59.
It is pivoted between. The pinion gear 62 meshes with a rack 64 formed at the end of the moving rod 59, and when the shaft 63 is rotated using a screwdriver or the like, the pinion gear 62
Rotates and the moving rod 59 slides. The shaft 60 in FIG. 4 is at the position closest to the elongated hole 55, and when the movable rod 59 is slid in this state, the shaft 60 gradually separates from the elongated 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 has the elongated holes 54 and 55 inside the drum shaft 21.
Slide away from the wire 1
The slack of 1 and 12 is adjusted. 65 is a pinion gear 62
The ratchet wheel 66 is integrally formed with the ratchet wheel 66, and the ratchet wheel 66 meshes with the ratchet wheel 65 to prevent the pinion gear 62 from rotating in the reverse direction.

10 to 12 show a power slide unit 7a of the second embodiment. In this embodiment, the means for manually releasing the clutch, the mechanism for adjusting the wire tension pressure, and the like are changed. This will be described below.

In the first embodiment, when the motor 8 fails in the completely closed position or the completely opened position and the clutch cannot be released, the guide plate 32 is rotated through the outer sleeve 44 and the spring 46 to open the clutch. Although it has been released, 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 wire drum 10a is rotated to release the clutch. In other words, in the clutch release by the manual sliding of the slide door 5 described in the column of “0019”, the slide door 5 is manually slid in order to rotate the wire drum 10. Therefore, in the second embodiment. , The wire drum 10a without moving the slide door 5
Is rotatable so that the clutch can be manually released in the completely closed position or the completely opened position. In order to rotate the wire drum 10a without moving the slide door 5, it is sufficient to loosen the tension of the wires 11 and 12. When the tension is loosened, the wire drum 10a can be rotated even if the slide door 5 does not move by the amount of the looseness. Specifically, as shown in FIGS. 11 and 12, the wire drum 10
A tooth portion 90 is integrally formed with a, and a cancel gear 92 fixed to a cancel shaft 91 is meshed with the tooth portion 90. One end of the cancel shaft 91 penetrates the base plate 19a and projects outward, and when the projecting end is rotated using a screwdriver or the like, the wire drum 1
0a rotates manually.

In the second embodiment, the member corresponding to the outer sleeve 44 of the first embodiment is unnecessary. The spring 4
The flange 45a with which one end of 6a abuts is the inner sleeve 4
3a.

The tension adjusting mechanism of the second embodiment is provided for each wire 11, 12. FIG. 13, FIG.
4, numeral 93 is a slide member provided between the base plate 19a and the cover plate 20a, and a tension roller 52a is axially supported by a tension shaft 53a inside one end side thereof. The slide member 93 is provided with four engaging pins 94, and the engaging pins 94 are elongated holes 54 formed in both plates 19a and 20a.
It is slidably engaged with a and 55a. 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 and 20a. As shown in FIG. 10, the tension roller 5
The wires 11 and 12 wound around 2a are bent substantially at 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.

On the outer circumference of the wires 11 and 12, 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 or 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 are unnecessary. One end of the wire shell 99 is locked to the shell holder 100 as shown in FIGS. The other end of the wire shell 99 is not shown, but the opening 9
It is locked to a shell holder provided in the vicinity of 7, 98. The shell holding body 100 is a separate body from the slide member 93 and is not engaged with each other. The shell holder 100 is provided with engagement protrusions 103 that slidably engage with the long holes 101 and 102 formed in both 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 is connected to the plates 19a, 2 by the shaft 106.
It is axially supported between 0a, and when the shaft 106 is rotated by using a screwdriver or the like, the pinion gear 105 rotates and the shell holding body 100 slides. Reference numeral 107 is a ratchet wheel integrally formed with the pinion gear 105, and 108 is a ratchet wheel 107
Is a ratchet that meshes with the pinion gear 105 to prevent the pinion gear 105 from rotating in the reverse direction, and 109 is a spring that biases the ratchet.

The shell holder 100 and the opening 9 of the outer plate 1
The length of the wire shell 99 between 7 and 98 is always kept constant because the wire shell 99 is a material that does not expand and contract, and therefore the direction in which the shell holding body 100 moves away from the wire drum 10a (see FIG. 13). When it is slid to the right), the length of the wire between the shell holding body 100 and the wire drum 10a becomes long, so that the arrangement length of the wire as a whole becomes long and the wires 11 and 12 are in a tensioned state. Becomes On the contrary, shell holder 1
When 00 is brought closer to the wire drum 10a, the total length of the wires arranged becomes shorter, and the wires 11, 12
Will loosen. When assembling the power slide unit 7a, the shell holder 100 is made to be closest to the wire drum 10a so that the wire is sufficiently loosened and then slid in the tension direction so that the wire tension pressure can be increased. Perform the initial adjustment of. After adjusting the shell holder 100, the tension spring 9
The slack of the wire is absorbed by the tension roller 52a which is moved by the elasticity of 6.

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

3 is connected. The connector 70 and the connector 82 are set so as to contact each other just before the sliding door 5 enters the half-latched state, and in the half-latch state, the power of the battery 83 can be surely supplied to the power closing unit 69. To

In FIG. 2, reference numeral 84 is an optical sensor (unit) that detects the rotation speed, rotation amount and rotation direction of the perforated flange 85 provided on the wire drum 10 and outputs it as a pulse signal. The rotation speed of the perforated flange 85 is equal to the movement speed of the slide door 5, the rotation amount is equal to the movement distance (position) of the slide door 5, and the rotation direction is equal to the movement direction of the slide door 5. The rotation direction is detected by the timing difference between the output pulses of the pair of sensors. The optical sensor 84 operates with the power of the battery 83, but consumes a considerable amount of dark current (about 65 mA) even in an unused standby state.
The power supply is stopped by step 6. 87 is a control unit,
89 is an ammeter for measuring the current value (load) of the motor 8.

[0037]

The overall operation will be described with reference to the flow chart.

(Opening control) When the opening operation switch is turned on (S003), the stop position of the slide door 5 is confirmed (S01).
1) If the door is closed in the half-latch state or the full-latch state, the flow goes to the door opening subroutine (S013). FIG.
When the flow goes to the door opening subroutine of 7, the chime is sounded (S201), and then the power opening unit 68 connected to the battery 83 through the connector 70 and the connector 82 is operated to release the ratchet 73 from the latch 72. Let
The timer T4 is started, and power is supplied to the optical sensor 84 whose power supply was stopped in the closed state.
(S203) Subsequently, the motor 8 of the power slide unit 7 is rotated to open the door to start the timer T5 (S205).

When the motor 8 rotates to open the door, the speed reduction mechanism 9,
Rotating plate 26 via gear 24 and reinforcing plate 25
3 turns to the right in FIG.
The swing arms 28 and 29 connected by 31 are rotated to the right, and the engagement pin 33 of the swing arm 28, which is engaged with the guide slot 35 of the guide plate 32, is also moved. At this time, since the guide plate 32 is held by the spring 46 so as not to rotate together, the engaging pin 33 enters the push-out slot 39 of the guide slot 35 from the position shown in FIG. The moving arm 28 swings around the pin 30 in the direction away from the drum shaft 21, and
The clutch claw 47 of 8 is the engaging protrusion 4 of the wire drum 10.
2. Abut and engage with 2. On the other hand, in the swing arm 29, since the engaging pin 34 only moves in the arc slot 38 of the guide slot 36 centered on the drum shaft 21, the pin 3
There is no swing around 1.

When the clutch claw 47 and the engaging projection 42 are in abutting engagement, the clutch is engaged (see FIG. 8), and the rotation of the rotary plate 26 is directly transmitted to the wire drum 10.
The wire drum 10 turns right in FIG. Thereby, the wire drum 10 winds the rear wire 12 and pulls out the front wire 11 by the same amount,
The slide door 5 starts sliding backward (opening direction).

When the slide door 5 is normally opened and slid, the door side connector 70 is separated from the vehicle body side connector 82 (S207). However, if it is not confirmed that the connectors are separated from each other by the time the timer T4 is up (S213), the power opening unit 68 or the power sliding unit 7
It is considered to be a malfunction of the slide or a slide failure due to freezing of the door 5 and the vehicle body 2. Therefore, when the latch 72 remains the full latch or the half latch (S215), the optical sensor 8
4 is stopped (S217), and when the latch 72 is already released from the striker 71, the power supply to the optical sensor 84 is not stopped and the power opening unit 68 is operated. Is stopped (S219), and then the plus / minus of the power supply to the motor 8 of the power slide unit 7 is reversed to move the motor 8 in the opposite direction (closing direction).
Then, it is rotated for a predetermined time (predetermined amount) (S221) to recover.

The reason why the motor 8 is rotated in the opposite direction for a predetermined time (predetermined amount) and then restored is that the clutch claw 47 of the swing arm 28 is engaged with the engagement protrusion 42. This is for canceling the entered state. That is, when the motor 8 is rotated in the opposite direction for a predetermined time (predetermined amount) in the state of FIG. 8, the rotation plate 26 rotates counterclockwise, so that the clutch pawl 47 of the swing arm 28 moves away from the engagement protrusion 42. Also, the engaging pin 33 of the swing arm 28 moves in the pushing slot 39 of the guide slot 35 toward the arc slot 37, whereby the swing arm 28 moves to the drum shaft 21 about the pin 30. It swings in the approaching direction and returns to the state of FIG. In this state, the connection between the wire drum 10 and the motor 8 side is disconnected (the clutch is disengaged), and thereafter the wire drum 10 is restored to a state in which it can rotate in any direction.

When the door-side connector 70 is separated from the vehicle-body-side connector 82 by the normal door-opening slide of the slide door 5 (S207), the power door-opening unit 68 is stopped (S209),
Then, the integration of the number of pulse signals output from the optical sensor 84 is started (S211). Since the integrated pulse number corresponds to the rotation amount of the wire drum 10, the position of the slide door 5 can be obtained from the integrated pulse number. Note that one of the features of the present application is that the timing of starting the integration of the number of pulses is set when the connectors are separated from each other. That is,
The position of the door 5 can be accurately monitored because the unstable pulse signal immediately after the start of the power feeding is not integrated and the integration is started after the pulse signal is stabilized by passing through one reference point.

While the sliding door 5 is sliding backward, the control section 87 monitors the interval of the pulse signal sent from the optical sensor 84 as a pulse speed, and at the same time,
The current value of the ammeter 89 is monitored (S223). Here, the pulse speed is the rotation speed of the wire drum 10 (slide door 5
The current value of the ammeter 89 is proportional to the motor 8
Therefore, if the moving speed of the slide door 5 becomes abnormally slow, or if the load current value of the motor 8 becomes abnormally large, it is considered that the slide door has caught a foreign object. In such a case, the motor 8 is rotated in the closing direction for a predetermined time (a predetermined amount) to disengage the clutch (S233) and then restored. As described above, one of the features of the present application is that the slide abnormality is monitored using the pulse signal, and the abnormality can be promptly detected as compared with the conventional method in which the load of the motor 8 is detected by using the pulse signal. Can be detected. Further, by using the pulse signal, it is possible to prevent erroneous detection of these even if the slide speed as a whole becomes slow due to a decrease in battery voltage or an increase in slide resistance.

When the slide door 5 normally slides backward, before the timer T5 is up (S235), the slide door 5 is moved to the position immediately before the full-open stopper 110 which holds the slide door 5 in the fully open position. Reach This position confirmation is
It is calculated by the integrated number of pulses (S225). After reaching the position immediately before the full-open stopper 110, thereafter, the abnormality monitoring using the pulse speed is not performed, and only the abnormality monitoring by the load current value of the motor 8 is performed (S227). This point is also one of the features of the present application. That is, the rotation of the wire drum 10 is detected by the optical sensor 8
When measured in step 4, the rotation amount as well as the rotation amount can be obtained at the same time. Since this rotation amount is equal to the movement amount of the slide door 5 as described above, the position of the slide door 5 can be constantly monitored. As a result, it becomes possible to use the abnormality monitoring control with a stable pulse speed having good responsiveness only in an appropriate portion (a section where the slide resistance is constant).

When the slide door 5 slides rearward past the position just before the full-open stopper 110, the sliding door 5 gets over the full-open stopper 110 and becomes a full-open door. Whether the door is in the completely open position can be confirmed by detecting the amount of movement of the slide door 5 by integrating the pulse signals from the optical sensor 84, detecting the overcurrent of the motor 8 when overcoming the stopper, or the like (S229).
When the door is completely opened, the motor 8 of the power slide unit 7 is rotated in the reverse direction (door closing direction) for a predetermined time (predetermined amount) to disengage the clutch (S233) and then restored.

The door opening control up to this point is the case where the door opening operation switch is turned on in the door closed state, but the power slide unit 7 is operated by manually opening the open handle.
Can also be started. In this case, the latch 72 and the striker 71 are manually released from the control, so that the operation of the power door opening unit 68 is not required, and the door opening control is almost the same.

When the latch 72 is released from the striker 71 in S011, the same control as the manual door-opening operation follow-up control (S015) described below is performed.

(Following Control of Manual Door Opening Operation) When the sliding door is stopped at an intermediate position, since the latch 72 is released from the striker 71, the optical sensor 84 is supplied with power. In this state, when the door is manually opened and slid, the wire drum 10 rotates, so that the optical sensor 84 outputs a pulse signal, whereby the manual door open slide is detected (S005), and the door manually opens. The flow proceeds to the door operation follow-up subroutine (S015), and thereafter the door is opened by the power of the motor 8.

That is, when the subroutine for following the manual door opening operation in FIG. 19 is flown, the chime is sounded (S301), and then it is confirmed whether the connector 70 and the connector 82 are in contact with each other (S303). When the contact is not made, the number of pulses is not reset, and the number of pulses is automatically integrated by the opening rotation of the wire drum 10.
The motor 8 is rotated in the door opening direction, the timer T5 is started (S305), and then flown to S223 of the door opening subroutine, whereby the door opening by the power already described is performed thereafter.

On the other hand, when the connectors are in contact with each other in S303, the integrated pulse number is reset, so the timers T4 and T5 are started and the motor 8 of the power slide unit 7 is opened in the door opening direction. (S307), and the slide door 5 is opened and slid. As a result, when the door is normally opened and slid, the connectors are separated from each other until the timer T4 is up (S311) (S309), and then the process proceeds to S211 of the door opening subroutine to open the door by power as described above. The door is done.

(Closed door control) Latch 72 is striker 71
When the door is released from the door, the optical sensor 84 is powered, and when the closing operation switch is turned on (S007), the stop position of the slide door 5 is confirmed (S019), and the door is engaged with the full-open stopper 110. If the door is in the fully open position, the flow goes to the door closing subroutine (S021) and the chime is sounded.
(S401), the motor 8 of the power slide unit 7 is rotated in the closing direction to start the timers T1 and T2 (S40
3).

Then, the rotating plate 26 turns counterclockwise in FIG. 3 via the reduction mechanism 9, the gear 24, and the reinforcing plate 25, and the swinging arm 29 swings around the pin 31 according to the same principle as when the door is opened. The clutch claw 4 of the swing arm 29 is moved.
8 engages with the engaging convex portion 42 of the wire drum 10, whereby the wire drum 10 rotates counterclockwise to wind up the front wire 11 and pull out the rear wire 12 by the same amount, so that the slide door 5 is closed. Slide along the guide rail 4 forward. Note that the pulse number is subtracted by the rotation of the wire drum 10 when the door is closed, contrary to the case when the door is opened.

When the slide door 5 normally slides forward due to the rotation of the wire drum 10, the slide door 5 passes over the full-open stopper 110 (S405) before the timer T1 is up (S407). To get over the stopper,
This is confirmed by the amount of movement of the slide door 5 based on the number of pulses. When it is not possible to confirm that the stopper has passed over within the time, the motor 8 is rotated in the opposite direction for a predetermined time (a predetermined amount) for the purpose of disengaging the clutch (S431), and the motor is restored.

When the stopper is normally overcome (S405),
The moving speed of the sliding door 5 and the load current value of the motor 8 obtained from the pulse signal are monitored (S409), and if there is any abnormality, it is considered as an abnormality such as pinching, and the door is urgent. Open the door. That is, if something goes wrong, timer T
After starting 3 (S433), until the timer T3 is up (S439) or until the door opening operation switch is turned on (S437), after issuing an alarm, start the timer T5 and start the power slide unit 7 The motor 8 is rotated in the door opening direction (S443), and thereafter, the process proceeds to S223 of the door opening subroutine to close the door by power as already described.

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 (S41) before the timer T2 is up (S413).
1), the number of pulses is reset (S415). When the connectors come into contact with each other, the power closing unit 69 receives power from the battery 83 and becomes operable. Further, the sliding door 5 after the connector 70 and the connector 82 are in contact with each other is
Since the slide resistance changes, the abnormality monitoring by the pulse signal is stopped thereafter, and only the load current of the motor 8 is monitored (S417). Even after the connectors are in contact with each other, the sliding door 5 slides in the closing direction by the power of the motor 8, whereby the latch 72 of the latch unit 67 engages with the striker 71 and rotates, and the ratchet 73 half-latches the latch 72. The stepped portion 74 is engaged and the half-latch state is established (S419).

In the half-latch state, the optical sensor 8
The power supply of No. 4 is stopped (S423), and the motor 8 of the power slide unit 7 is rotated in the opposite direction for a predetermined time (a predetermined amount) for the purpose of disengaging the clutch (S425). The sliding by the motor 8 is up to the half-latch state in this way, but in rare cases, even if the motor 8 is stopped, the door may close to the full-latch as it is. When the full latch is reached (S427), the control is stopped as it is because the door has been closed. However, when the half latch remains, the power closing unit 69 is operated (S429) and the shaft 76 is rotated. Turn right at 6. Then, the lever 77 rotates, the roller 79 moves to the right while being guided by the guide groove 80, contacts the leg portion 81 of the latch 72 in the half latch position, and rotates the latch 72 toward the full latch position. When the full latch state is reached, the closing of the door is completed, so the power closing unit 69 is stopped and the control is ended.

When the load current is abnormal in S417, the flow proceeds to S307 of the manual door-opening operation follow-up subroutine, and thereafter door opening by power is performed. Also, in S019,
When the door is located closer to the closing side than the full-open stopper 110, the same control as the manual closing operation following control described below is performed.

(Following Control of Manual Door Closing Operation) When the sliding door is in the middle position, the latch 72 is released and the optical sensor 84 is supplied with power. From this state,
When the door is manually closed and slid, the wire drum 10 rotates, so that the optical sensor 84 outputs a pulse signal, whereby the manual sliding of the door is detected (S009). When the manual door closing slide is detected, it is confirmed from which point the slide is coming from (S025), and when it is the sliding from the door closing side from the full-open stopper 110, the flow directly goes to the manual door closing operation follow-up subroutine (S033), and the power is output. When the slide from the state of engaging the full-open stopper 110 is started, the timer T6 is activated (S027), and only when the full-stop stopper 110 is moved within the time (S029), the manual operation is performed. Allow the flow to the closing operation follow-up subroutine.

When the flow proceeds to the manual door closing operation follow-up subroutine, the chime is sounded (S501), the timer T2 is started, the motor 8 of the power slide unit 7 is rotated in the door closing direction (S503), and then the door closing subroutine S409.
After that, the door is closed by power as described above.

(Clutch Release at Motor Failure) In the present invention, the clutch is released by reversing the motor by a predetermined amount. Therefore, when the motor 8 fails, the clutch cannot be released by the normal means. Hereinafter, this point will be described. If the motor 8 breaks down while the sliding door 5 is sliding backward (opening direction), the clutch claw 47 of the swing arm 28 remains engaged with the engaging projection 42. Then, it becomes very difficult to manually slide the sliding door 5 to the front side. In such a case, the slide door 5 is manually moved slightly in the movable direction, that is, backward. Then, the wires 11 and 12 are moved by the backward movement of the slide door 5, and the wire drum 1 is moved.
0 turns right by itself from the state of FIG. At this time, since the outer sleeve 44 does not rotate, the guide plate 32 also does not rotate. When the wire drum 10 rotates about half a rightward direction, another engaging protrusion 42 abuts on the cancel surface 49 of the swing arm 28, and when the wire drum 10 further turns to the right, the engaging protrusion 42 and the cancel surface 49 are formed. The abutment of the rocking arm 28 causes the rocking arm 28 to rock around the pin 30 toward the drum shaft 21, the engaging pin 33 returns to the arc slot 37 of the guide slot 35, and the clutch is disengaged. Thereby, thereafter, the slide door 5 can be slid in any of the front and rear directions.

When the sliding door 5 has slid backward to the fully opened position and the motor 8 cannot rotate in the reverse direction, it is difficult to disengage the clutch in the manner described in the section "0061". That is, since the slide door 5 in the completely open position hardly moves backward, the amount of manually rotating the wire drum 10 becomes extremely small, and it is practically 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 by using pliers or the like, which causes the guide plate 32 to move through the outer sleeve 44 and the spring 46. Turn right at 8. Then, due to 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 arcuate slot 37, the state of FIG. 3 is restored, and the clutch is disengaged. When rotating the metal ring 51, loosening the tension of the wires 11 and 12 facilitates the work. If the clutch cannot be disengaged when the slide door 5 is in the completely closed position,
The guide plate 32 may be rotated counterclockwise.

In the second embodiment, instead of rotating the metal ring 51, the wire drum 10a is rotated through the cancel gear 92 to disconnect the clutch. This will be described below. In the state of FIG. 13, the shell holder 100 is
Sliding to the right by the pinion gear 105, 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 long. On the other hand, the length of the wire shell 99 between the shell holder 100 and the openings 97, 98 of the outer plate 1 is constant, and the wire shell 99
Since the lengths of the wires 11 and 12 in the interior of the wire are also constant, the arrangement length of the wire as a whole becomes long, whereby the wires are in a tension state. Therefore, in FIG.
In 3, remove the ratchet 108 from the ratchet wheel 107,
Release the pinion gear 105 and free the shell holder 100. Then, since the wires 11 and 12 try to loosen the tension state, the shell holding body 100 is moved to the left side in FIG. 13 so as to approach the wire drum 10a, and the bare portion between the shell holding body 100 and the wire drum 10a is removed. Shorten the wire part of. As a result, the overall length of the wires 11, 12 is shortened 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 shell holder 10 does not move with respect to the moving amount of the tension roller 52a.
If the movement amount of 0 is set to a large value, the wire will loosen greatly.

When the wire is slackened in this way, the wire drum 10a can be rotated without moving the slide door 5 by the amount of the slack wire. Therefore, the cancel axis 91
To cancel the gear 9
The wire drum 10a is rotated via 2. When the wire drum 10a is rotated in this manner, the same principle as when the slide door 5 is manually moved (“006
The clutch can be released. The second
In the embodiment, since many engaging protrusions 42a of the wire drum 10a are formed, the clutch can be released with a small rotation amount of the wire drum 10a.

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

In the second embodiment, the wires 11, 1
The tension pressure of 2 is classified into an initial adjustment by the shell holder 100 and a subsequent fine adjustment by the tension spring 96. First, when the power slide unit 7a is assembled, the shell holder 100 is placed closest to the wire drum 10a so that the assembly can be performed easily. Then, the shell holder 100 and the opening 9 of the outer plate 1
The length of the wire shell 99 between 7 and 98 is kept constant because the wire shell 99 is a material that does not expand and contract, so the shell holder 100 and the wire drum 1
Since the length of the bare wire between 0a and 0a is short, the wire installation length as a whole is shortened, and the wire is in a slackened state, which facilitates assembly. After the assembly is completed, when the shaft 106 is rotated by using a screwdriver 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 is meshed with 5 moves to the right in FIG. 13 and separates from the wire drum 10a. Then, the overall length of the wire is increased, and the wire is gradually strained. Wires 11 and 12
When a predetermined tension is reached, the initial setting ends. After the initial setting is completed, the tension roller 52a that is moved by the elasticity of the tension spring 96 absorbs the looseness of the wire.

In the present invention, as described above, the optical sensor 8
Although the rotation amount of the wire drum 10 is obtained by integrating the pulse signals sent from No. 4, there are other methods for obtaining the rotation amount from the pulse signal, and the method is not limited to the exemplified method.

[0068]

As described above, according to the present invention, the slide door 5 slidably attached to the vehicle body 2 and the striker 71 fixed to the vehicle body 2 provided on the slide door 5 are provided.
By rotating the wire drum 10 and the latch unit 67 which is connected to the slide door 5 through the wires 11 and 12 by engaging with A motor 8 for sliding the sliding door 5 in the closing direction and the opening direction, a door opening control for rotating the motor 8 to open the sliding door 5, and a sliding operation for rotating the motor 8 to close the door.

And a battery 83, and the control unit 87 stops or reverses the motor 8 when the rotation speed is abnormal during the sliding of the slide door 5. The power supply to the sliding door power slide device is not performed when the latch unit 67 is in the half-latch state or the full-latch state. It does not burden the battery 83 even when parked. Further, according to the present invention, in the above device, when the slide door 5 is opened from the full latch state, the optical sensor 84 does not wait until the full latch state or the half latch state is released.
Since the power sliding device for the slide door that supplies the power of the battery 83 is used, the power supply to the optical sensor 84 is not delayed and the detection of the slide abnormality of the slide door 5 is not delayed. Further, in the present invention, in the above device, when the optical sensor 84 is in a full latch state or a half latch state even after a lapse of a predetermined time after power supply to the optical sensor 84,
Since the power sliding device for the slide door that stops the power supply to the battery 8 is provided to the optical sensor 84 without waiting for the release of the full latch state or the half latch state.
Even if the power of 3 is supplied, if there is an abnormality in the release of the latch 72 after that, the power supply is stopped.
Don't strain 3.
