Abstract

PROBLEM TO BE SOLVED: To realize a sliding door in which an intermediate stopper mechanism is combined with an automatic opening device such that a sliding door main body is prevented from performing an inappropriate action. SOLUTION: The sliding door is comprised of the automatic opening device which drives a sliding door opening motor in response to switch operation, thereby fully opening the sliding door main body in any event, and inverts the sliding door opening motor when an overload state of the same is detected during the fully opening operation, thereby returning the entire of the sliding door to a fully closed state. When the overload state of the sliding door opening motor is generated under a condition in which the intermediate stopper mechanism is operated, the automatic opening device is constructed such that the sliding door main body which has once been opened to some mid point to the fully opened state, does not return to the closed state without the need therefor.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door having a sliding door body openably and closably mounted on a side of a vehicle or the like, and relates to a window regulator for raising and lowering a window glass, and movement of the sliding door in the opening direction during opening. An intermediate stopper mechanism that can restrict the movement of the slide door in the opening direction to a predetermined range when the window glass is opened to a certain degree or more. For sliding doors.

[0002]

2. Description of the Related Art As shown in FIG. 9, in a sliding door of a vehicle or the like, a window glass 1 is provided on a sliding door body (opening / closing moving section) 3 so as to be able to move up and down. For this reason, when an object is inserted into the window of the slide door body 3 when the slide door body 3 is opened with the window glass 1 lowered, the object is removed from the window frame 7 and the pillar 9 of the slide door body 3. And may be damaged.

In order to avoid this situation, it has been proposed to provide an intermediate stopper mechanism to stop the sliding door moving in the opening direction during opening when the window glass 1 is lowered below a predetermined position. Have been.

FIG. 10 shows an example of this sliding door.
There is something like that shown in First, while the window glass 1 is lowered by a predetermined amount L (for example, 150 mm) from the fully closed state, the intermediate stopper control mechanism 11 draws in the cable (inner cable) 13 according to the amount of the lowering. On the other hand, when the movement stroke of the cable 13 reaches the set value, the drawing of the cable 13 is stopped. However, even in this situation, the window glass 1 can descend.

The intermediate stopper mechanism 15 is connected to the intermediate stopper control mechanism 11 by a cable 13. The intermediate stopper mechanism 15 is driven by the intermediate stopper control mechanism 11 and stops the sliding door body 3 moving in the opening direction during opening.
The X-arm type window regulator 16 drives the window glass 1 in the vertical direction.

Here, the intermediate stopper control mechanism 1
1 will be described in detail with reference to FIG. A base plate 31 is fixed to the inner panel of the slide door body 3, and pins 33 are erected on the base plate 31. A first lever 35 and a second lever 37 are rotatably attached to the pin 33.

The spiral spring 39 has a pin 3
3, one end 39a is hooked on the first lever 35, and the other end 39b is wound on the second lever 37.
Hanged on.

A roller 41 is provided at the rotating end of the first lever 35, and the roller 41 is engaged with the guide 17 provided below the window glass 1 so as to be movable in the horizontal direction in the figure. are doing. The cable 13 is connected to the second lever 37.

Next, the structure of the intermediate stopper mechanism 15 is shown in FIG.
2 will be described. A base plate 21 is fixed to a lower portion of the inner panel of the slide door body 3, and a lever 22 is rotatably mounted on the base plate 21. The lever 22 is connected to the cable 13,
Further, it is urged in the direction of arrow I by urging means (not shown). An elastic roller 24 is provided at the tip of the lever 22. On the other hand, on the vehicle body 26 side, a step portion 28 that can contact the roller 24 is formed.

In the above conventional slide door body 3,
Fully closed window glass 1 to window regulator 1
6, the first lever 35 also rotates counterclockwise in FIG. 11 with the lowering of the window glass 1. Since the second lever 37 is also connected to the first lever 35 via the spiral spring 39, the second lever 37 rotates counterclockwise to draw in the cable 13.

When the movement stroke of the cable 13 reaches the set value, the rotation of the second lever 37 is restricted, and
It becomes impossible to rotate following the first lever 35. However, even in this situation, the spiral spring 39
Is elastically deformed so as to reduce the diameter of the first lever 3.
Only 5 can be rotated counterclockwise, and the window glass 1 can be lowered.

Therefore, when the window glass 1 is lowered from the fully closed state by a predetermined amount L or more, the intermediate stopper control mechanism 11 pulls in the cable 13 by a predetermined amount and the lever 2
2 rotates against the urging force of the urging means (not shown), and moves from the two-dot chain line position to the solid line position in FIG.

In this state, when the slide door body 3 is moved in the opening direction, the roller 24 comes into contact with the step 28 on the vehicle body side and stops at that position, so that the slide door body 3 cannot be further opened. That is, the sliding door body 3
In this case, even if the window glass 1 is lowered and an object is inserted into the window of the sliding door body 3, in this situation, there is always a space between the window frame 7 of the sliding door body 3 and the pillar 9. It is possible to avoid a situation where an object inserted into the window is pinched.

[0014]

As described above, with the provision of the intermediate stopper mechanism, when the slide door body is moved in the opening direction when the window glass is lowered by a predetermined amount or more from the fully closed state, The sliding door body stops at the intermediate position and cannot be opened any further. For this reason, it is possible to avoid a situation where an object inserted into the window is pinched.

On the other hand, in a one-box car or the like, a device (automatic opening / closing device) capable of automatically fully opening a sliding door of a rear seat by a switch operation of a driver seat is required.
Here, the automatic opening / closing device is configured to return the slide door body to the fully closed position when the movement of the slide door body in the fully open direction is interrupted for some reason during the fully open operation and the slide door opening / closing motor is overloaded. Operate. For this reason, if a slide door combining a conventional intermediate stopper mechanism and an automatic opening / closing device is assumed, the operation of the intermediate stopper mechanism restricts the movement of the slide door main body, so that the operation of the automatic opening / closing device may cause interference. In this situation, the automatic opening and closing device returns the slide door body to the fully closed position.

However, when the sliding door main body is once opened halfway and turned back immediately, the sliding door main body may pinch the passenger's luggage or the like who gets off the vehicle and damage the same.

In the conventional sliding door shown in FIGS. 9 to 12, not only in relation to the automatic opening / closing device, but also in the original configuration of the sliding door.
There are the following problems. That is, since the intermediate stopper control mechanism 11 is configured to directly obtain the descending amount of the window glass 1 by the first lever 35, the lever 35 becomes long, occupies a large space, and the intermediate stopper control mechanism 11 There is a problem that the device itself becomes large.

When the window glass 1 is lowered from the fully closed state in the slide door body 3, the intermediate stopper control mechanism 11 gradually pulls the cable 13 before the window glass 1 reaches the predetermined amount L. The lever 22 also rotates gradually. Therefore, window glass 1
When the sliding door body 3 is strongly pulled in the opening direction in a state where the descent of the sliding door is slightly smaller than the predetermined amount L, the roller 24
After abutting on the sliding door body 3
Moves to the fully open position.

Therefore, during the switching operation of the intermediate stopper mechanism 15, the roller 24 is in a halfway state for a long time, and in this halfway state, the roller 24 advances over the step 28.

In sliding the slide door body 3 in this state, the roller 24, the lever 22, the base plate 2
A large load is applied to 1 and the like, and not only the durability of these components is lowered, but also abnormal noise is generated, the opening operation force of the slide door body 3 is increased, and the operation feeling is deteriorated.

Further, when the window glass 1 has dropped by a predetermined amount L or more, the intermediate stopper mechanism 15
It is necessary to stop the slide door body 3 by reliably hitting the step portion 28 on the vehicle body side. But Roller 2
Since 4 is halfway in a wide range, it is absolutely necessary to adjust the mounting state of the base plate 21 by trial and error in order to obtain reliable operation.

An object of the present invention is to provide a slide door which solves the above-mentioned problems of the conventional slide door. That is, a first object of the present invention is to realize a slide door in which an intermediate stopper mechanism and an automatic opening / closing device are combined so that the slide door body does not operate inappropriately. A second object of the present invention is to provide a sliding door which does not cause an incomplete state when switching the intermediate stopper mechanism. A third object is a sliding door capable of reducing the size of the intermediate stopper control mechanism. It is to realize.

[0023]

According to a first aspect of the present invention, there is provided a window regulator for raising and lowering a window glass, and restricting movement of the sliding door body in the opening direction during opening within a certain range. Possible intermediate stopper mechanism, when the opening of the window glass is more than a certain,

An automatic opening / closing device that, when detecting an overload state of the sliding door opening / closing motor during the full opening operation, reverses the sliding door opening / closing motor and returns the sliding door body to the fully closed position;
In a situation in which the intermediate stopper mechanism is operated and in a regulated state, even if an overload state of the slide door opening / closing motor occurs, simply stopping the slide door body causes the fully closed position of the slide door body. Is not performed.

If the slide door whose window glass is opened to a certain degree or more is to be fully opened by a switch operation, an overload state of the slide door opening / closing motor occurs due to the regulation of the intermediate stopper mechanism. However, according to the present invention, when an overload state of the sliding door opening / closing motor occurs due to the regulation of the intermediate stopper mechanism, the sliding door body once opened halfway does not turn back, and the occupant's luggage trying to get off the vehicle does not return. The sliding door body does not get caught. Therefore, the luggage and the like are not damaged.

According to a second aspect of the present invention, there is provided a window regulator for raising and lowering the window glass, an intermediate stopper mechanism capable of restricting movement of the slide door body in the opening direction during opening within a certain range, and opening of the window glass.

When reaching the vicinity of the target value, the slide door body is only stopped, and the operation of returning the slide door body to the fully closed position is not performed.

In the present invention, the same operation as the sliding door according to the first aspect is performed when the intermediate stopper mechanism is not operated. On the other hand, when the opening of the window glass is equal to or more than a certain value and the intermediate stopper mechanism is operating, the opening target value of the slide door body by the automatic opening / closing device is set within the opening restriction range by the intermediate stopper mechanism. For,
Even if the slide door is opened by a switch operation, the slide door body usually stops at a position restricted by the intermediate stopper mechanism or at a position immediately before the restriction. For this reason, an overload state of the sliding door opening / closing motor does not occur, and the sliding door body that has been opened halfway is not returned even though it is not necessary.

Further, during the opening operation of the slide door body, even if the slide door body is restricted by the intermediate stopper mechanism due to overrun and an overload state occurs in the slide door opening / closing motor, the opening degree of the slide door body is increased. When has already reached the vicinity of the opening target value, only the slide door body is stopped, and the operation of returning the slide door body to the fully closed position is not performed. Therefore, there is no need to return the slide door body that has been opened halfway, even if it is not necessary. Therefore, under the situation where the intermediate stopper mechanism is operating, the slide door body does not pinch the load or the like of the occupant trying to get off the vehicle.

According to a third aspect of the present invention, there is provided the window regulator according to the first aspect of the present invention, further comprising a lift arm having an intermediate portion rotatably supported, and a driven gear fixed to one end of the lift arm. The other end of the arm raises and lowers the window glass, the intermediate stopper control mechanism, the control lever rotatably supported, as a cam surface that is fixed to the driven gear, and slidably contacts the tip of the control lever, A cam plate having an inclined surface for rotating the control lever and an arc surface for holding the control lever in its position, one end of an inner wire is locked to the control lever, and movement of the control lever is controlled by the intermediate stopper mechanism. And a cable that transmits to the

A hook that is connected to the other end of the inner wire and is pulled by the inner wire when the window glass of the sliding door opens to a predetermined position to release the restraint of the pole, and a direction in which the hook is engaged with the pole. A signal indicating whether or not the intermediate stopper mechanism is operating is obtained from a sensor that detects the rotation of the control lever. Is what you do.

Even in the present invention, the operation of the fully open switch does not require the sliding door body to be opened halfway, so that the sliding door body does not need to be turned back. Absent. Therefore, the luggage and the like are not damaged. In addition, since the sensor that detects the rotation of the control lever determines that the intermediate stopper mechanism is operating and is in the restricted state, this determination can be made accurately and easily.

Further, in the present invention, the switching of the intermediate stopper mechanism is promptly performed, and the halfway state does not occur. Further, since the intermediate stopper control mechanism is configured to indirectly determine the amount of lowering of the window glass by using the displacement of the lift arm, the size of the intermediate stopper control mechanism can be reduced.

According to a fourth aspect of the present invention, a configuration is simplified by using a limit switch which is turned on / off by the other end of the control lever as a sensor for detecting the rotation of the control lever in the third aspect of the invention. It is intended.

According to a fifth aspect of the present invention, the limit switch according to the fourth aspect of the present invention is disposed in a space surrounded by the control lever, thereby preventing the limit switch from being damaged during assembly. is there.

The vehicle state detection sensor 202 outputs a signal indicating whether or not the vehicle is in a state in which it can respond to the request from the fully open switch 201. For example, when the ignition switch is off, the vehicle state detection sensor 202 responds to the request from the fully open switch 201. It outputs a signal to the effect.

Operation detecting means 20 of intermediate stopper mechanism 63
3 outputs a signal to that effect when the intermediate stopper mechanism 63 is operating. In the present embodiment, the control lever 153 controls the operation of the intermediate stopper mechanism 63.
The limit switch 171 detected from the rotation of the above corresponds to this.

The slide door fully open sensor 204 is a sensor that detects that the slide door is fully open, and the slide door fully closed sensor 205 is a sensor that detects that the slide door is fully closed.

The pulse generator 210 generates one pulse for every unit movement amount of the slide door main body. For example, a disk having slits formed radially at equal pitch is proportional to the moving speed of the slide door main body. The light-emitting element and the light-receiving element are arranged so as to rotate at a speed, and the light-emitting element and the light-receiving element are opposed to each other so as to sandwich the slit portion of the disk.

The motor drive circuit 220 drives the slide door opening / closing motor 221 in response to an external instruction to move the slide door body in the opening direction or the closing direction. When the sliding door body comes into contact with some obstacle and its progress is hindered, the sliding door opening / closing motor 221
Is overloaded, the moving speed of the slide door body is reduced, and the output pulse interval of the pulse generator 210 is increased.

The control unit 230 is the core of the automatic opening / closing device.
The slide door opening / closing motor 221 is driven via the motor drive circuit 220 to fully open the slide door body. However, when the vehicle state detection sensor 202 prohibits the shift to the full opening operation, the full opening operation is not performed.
Further, even after the full-opening operation is started, if the overload detecting means 231 detects an overload state of the sliding door opening / closing motor 221 during the full-opening operation, the sliding door opening / closing motor 2
21 is reversed to return the slide door body to the fully closed position.

Further, the fact that the intermediate stopper mechanism 63 has been operated and is in a regulated state is detected by the operation detecting means 203.
Is output, the sliding door opening / closing motor 21
Even if an overload state of 0 occurs, only the slide door body is stopped, and the slide door body is not returned to the fully closed position.

(Operation of the Embodiment) The operation of the above embodiment will be described below. In the intermediate stopper mechanism 63, when the slide door body is in the fully closed position and the window glass 113 is in the fully closed state, as shown in FIG.
The first hook 73 is engaged by the urging force of the second urging means on the pawl 71 rotated to a position where it cannot contact the intermediate striker 67.

When the motor 109 is driven to lower the window glass 113 in the fully closed state and the lift arm 105 moves in the direction of arrow N in FIG. 2, the cam plate 155 fixed to the driven gear 107 also moves in the same direction. Moving. Initially, the cam plate 155 has a small-diameter arc surface 155b and the distal end 15 of the control lever 153.
3a, but when the window glass 113 descends to the vicinity of a predetermined position, the front end 15a is inclined by the inclined surface 155a.
3a. And window glass 1
At the time when 13 has dropped to a predetermined position, it comes into contact with the leading end 153a with the large-diameter arc surface 155c.

At the time of sliding contact with the inclined surface 155a, the other end 153b of the control lever 153 is rotated in the direction of the arrow K to pull out the inner wire 75a of the cable 75. As a result, the first hook 73 is driven in a direction (counterclockwise in FIG. 1) separating from the pole 71, and when the window glass 113 falls to a predetermined position, the first hook 73 and the pole 71 The engagement is released.

Therefore, the pawl 71 rotates to a position where it comes into contact with the stopper 77 by the urging force of the first urging means when the pawl pushing back member 68 is no longer restrained, and the pawl 71 can be brought into contact with the intermediate striker 67. Becomes

When the sliding door body with the window glass 113 lowered to a predetermined position is moved in the opening direction,
With this movement, the pole 71 separates from the pole push-back member 68 and rotates to a position where it comes into contact with the stopper 77 as shown by a two-dot chain line. Moving further, Paul 7
Numeral 1 abuts on the intermediate striker 67 to prohibit further movement of the slide door body (intermediate lock state).

To release the intermediate lock state, the slide door is moved in the closing direction, returned to the position shown in FIG. 1, and the window glass 113 is raised from a predetermined position. By this return operation, the back surface of the pole 71 is pushed by the pole push-back member 68 provided on the vehicle body side, the pole 71 rotates in the direction opposite to the arrow D, and the first hook 73 is again moved to the pole 7.
1 and the intermediate lock state is released.

Next, the operation of the full-open stopper mechanism 65 will be described. When the slide door body is not fully opened, the latch 81 is at a position (the position shown in FIG. 1) at which the latch 81 can be engaged with the fully open striker 69 by the urging force of the third urging means.

When the slide door body moves in the fully opened direction, the fully opened striker 69 engages with the engagement groove 81a of the latch 81, and the latch 81 further rotates clockwise. When the latch 81 rotates to the position shown by the two-dot chain line, the second hook 83 is engaged with the latch 81 by the urging force of the fourth urging means, and the latch 81 is prevented from rotating in the direction of arrow F. State.

To release the fully open lock state, the inside handle or the outside handle is operated. Then, the cable 85 is pulled in, the engagement of the second hook 83 with the latch 81 is released, and the latch 81 is allowed to rotate in the direction of arrow F, and the fully open locked state is released. For this reason, the slide door body can be moved in the closing direction.

On the other hand, the operation of fully opening the slide door using the fully open switch 201 is performed based on, for example, the flowchart of FIG. That is, the control unit 230 determines whether the fully open switch 201 is on (step S1). If the fully open switch 201 is on, the output signal of the vehicle state detection sensor 202 is prohibited from shifting to the full open operation. It is determined whether or not there is (step S2).

If the shift to the full opening operation is not prohibited, the sliding door opening / closing motor 221 is driven via the motor driving circuit 220 (step S3), and the sliding door opening / closing motor 221 is output based on the output of the pulse generator 210.
While observing whether the overload state has occurred (step S4) or whether the slide door body has not reached the fully open position based on the output of the fully open sensor 204 (step S5),
The driving of the sliding door opening / closing motor 221 is continued. Then, when the slide door body reaches the fully open position, the drive of the slide door opening / closing motor 221 is stopped (step S).
6).

The control unit 230 controls the sliding door opening / closing motor 22 during the full opening operation even after the full opening operation is started.
When the overload state of No. 1 is detected by the overload detecting means 231 (step S4), it is confirmed that the intermediate stopper mechanism 63 is operated and the state is not under the regulation state (step S4).
7), the slide door opening / closing motor 221 is reversed (step S8), and whether the slide door opening / closing motor 221 is overloaded at the time of the reverse rotation (step S9), based on the output of the fully closed sensor 205, The reverse rotation drive of the slide door opening / closing motor 221 is continued while watching whether or not has reached the fully closed position (step S10). When the sliding door body returns to the fully closed position, the driving of the sliding door opening / closing motor 221 is stopped (step S).
6).

Here, the sliding door opening / closing motor 221
If an overload state occurs during the reverse rotation drive, the drive of the slide door opening / closing motor 221 is stopped for safety (step S6).

Even if an overload condition is detected in the sliding door opening / closing motor 210 in step S4, the output of the operation detecting means 203 indicates that the intermediate stopper mechanism 63 is operating in step S7. In step S6, only the slide door body is stopped, and the operation of returning the slide door body to the fully closed position is not performed. When the vehicle state detection sensor 202 prohibits the shift to the full-open operation, the full-open operation is not performed.

In the above embodiment, the window glass 1
If the opening of the sliding door 13 is more than a predetermined value, the intermediate stopper mechanism 63
, An overload state of the slide door opening / closing motor 221 occurs. However, in this configuration, even in this case,
Although the sliding door body that has been opened halfway is not needed, it does not turn back, and the sliding door body does not pinch the luggage or the like of the occupant trying to get off the vehicle. Therefore,
There is no damage to luggage and the like.

Further, the determination that the intermediate stopper mechanism 63 is in operation and in the restricted state is made by the limit switch 171 that detects the rotation of the control lever 153, so that this determination can be made accurately and easily. Moreover, since the limit switch 171 which is turned on / off by the other end 153b of the control lever 153 is used, the configuration is simplified. Further, by disposing the limit switch 171 in the space surrounded by the control lever 153, it is possible to prevent the limit switch 171 from being damaged at the time of assembly or the like.

In addition, in the slide door according to the present embodiment, the intermediate stopper mechanism 63 is constituted by the pawl 71 and the first hook 73, so that the switching is promptly performed, and a state in which the switching is incomplete is performed. Absent. Therefore, compared with the conventional slide door in which the switching is incomplete, no noise is generated, the durability of the parts is improved, and the operation force for moving the slide door body does not change. In addition, when the intermediate stopper mechanism 63 is mounted, it is not necessary to perform a troublesome adjustment of the mounting state, and the mounting operation is facilitated.

The intermediate stopper control mechanism 151
Reduces the amount of lowering of the window glass 113 by the lift arm 10.
Since the configuration is obtained indirectly using the displacement of No. 5, a long lever or the like is not required, the occupied space is reduced, and the intermediate stopper control mechanism 151 can be downsized.

The present invention is not limited to the above embodiment. For example, the determination that the intermediate stopper mechanism 63 is operating and in the restricted state may be made based on a movement other than the rotation of the control lever 153.

Further, the configuration of the full-open stopper mechanism 65 and the like is as follows.
It is not necessary to limit to the above embodiment. Further, the method of detecting the overload state of the slide door opening / closing motor 221 may be obtained directly from the change in the drive current of the motor, instead of indirectly from the decrease in the moving speed of the slide door body.

<Second Embodiment> The present embodiment is a modification of the automatic opening and closing device in the first embodiment, and the other structure is the same as that of the first embodiment. Have in common. The control operation of the automatic opening and closing device in the present embodiment is shown in the flowchart of FIG. Hereinafter, the control operation will be described using the same reference numerals as those of the components of the automatic opening / closing device (see FIG. 6) in the first embodiment.

The control unit 230 starts with the full open switch 201
Is determined (step S11), and if the fully open switch 201 is on, it is determined whether the output signal of the vehicle state detection sensor 202 is prohibited from shifting to the fully open operation (step S12).

If the shift to the full opening operation is not prohibited, the slide door opening / closing motor 221 is driven via the motor drive circuit 220 (step S13). Thereafter, it is determined whether or not the intermediate stopper mechanism 63 is operating. A determination is made (step S14). If the intermediate stopper mechanism 63 is not in operation, the slide door body has not reached the fully open position based on the output of the fully open sensor 204 (step S).
15) The driving of the slide door opening / closing motor 221 is continued while watching whether an overload state of the slide door opening / closing motor 221 occurs based on the output of the pulse generator 210 (step S16). When the sliding door body reaches the fully open position, the sliding door opening / closing motor 2
The driving of the motor 21 is stopped (step S17).

On the other hand, if it is determined in step S14 that the intermediate stopper mechanism 63 is operating, the slide door body has not reached the intermediate stop position (step S1).
5) The driving of the sliding door opening / closing motor 221 is continued while watching whether an overload state occurs in the sliding door opening / closing motor 221 (step S16). And
When the slide door body reaches the intermediate stop position, the drive of the slide door opening / closing motor 221 is stopped (step S).
17).

Here, the intermediate stop position is an opening target value of the slide door body by the automatic opening / closing device, and is set within the opening restriction range by the intermediate stopper mechanism 63. In the present embodiment, the upper limit value of the opening restriction range by the intermediate stopper mechanism 63 is usually used as the intermediate stop position.

The control unit 230 notifies the pulse generator 210 that the slide door body has reached the intermediate stop position.
Can be obtained by counting the output pulses (the counting is started from the fully closed sensor 205 being turned off). still,
Reaching to the intermediate stop position can also be known by providing a sensor for detecting that the slide door body has reached the intermediate stop position.

When the overload detecting means 231 detects an overload state of the slide door opening / closing motor 221 during the movement of the slide door body to the fully open position or the intermediate stop position (step S16), the intermediate stopper mechanism 63 is activated. Is operated to confirm that the vehicle is not in a regulated state (step S19), and the slide door opening / closing motor 221 is reversed (step S20). Step S2
1) The reverse rotation drive of the slide door opening / closing motor 221 is continued while watching whether the slide door body has reached the fully closed position based on the output of the fully closed sensor 205 (step S22). When the slide door body returns to the fully closed position, the reverse rotation drive of the slide door opening / closing motor 221 is stopped (step S17). Here, if an overload state occurs during the reverse rotation drive of the slide door opening / closing motor 221,
For safety, the driving of the slide door opening / closing motor 221 is stopped (steps S21, S17).

Even if an overload state of the sliding door opening / closing motor 210 is detected in step S19, if the sliding door body has reached near the intermediate stop position (step S23), the process proceeds to step S17. However, only the slide door body is stopped, and the operation of returning the slide door body to the fully closed position is not performed. This is because the slide door body may be overrun due to the displacement of the mounting position, the slide door body may be restricted by the intermediate stopper mechanism 63, and the slide door opening / closing motor may be overloaded. is there. With this configuration, even if there is an overrun, the operation of returning the slide door body to the fully closed position is not performed. The vicinity of the intermediate stop position is, for example, a position about 76.5 mm before the intermediate stop position.

As is apparent from the above description, in the present embodiment, the operation similar to that of the first embodiment is performed when the intermediate stopper mechanism 63 is not operated. on the other hand,
When the opening of the window glass is equal to or more than a certain value and the intermediate stopper mechanism 63 is operating, the opening target value of the slide door body by the automatic opening / closing device is set to the intermediate stopper mechanism 6.
3, the slide door body normally stops at or before the position restricted by the intermediate stopper mechanism 63 even if the slide door is opened by a switch operation. For this reason, the overload state of the sliding door opening / closing motor 221 does not occur, and the sliding door body that has been opened halfway is not required to be turned back.

As described above, during the opening operation of the slide door body, the slide door body is restricted by the intermediate stopper mechanism 63 due to overrun, and the slide door opening / closing motor 2
Even if an overload state occurs at 21, when the opening of the slide door body has already reached the vicinity of the opening target value, the slide door body is simply stopped to move the slide door body to the fully closed position. Since the return operation is not performed, there is no need to return the slide door body that has been opened halfway even if it is not necessary. Therefore, under the condition that the intermediate stopper mechanism 63 is operating, the slide door body does not catch the luggage or the like of the occupant trying to get off the vehicle.

[0104]

As described above, according to the first aspect of the present invention, even if an overload state of the slide door opening / closing motor occurs due to the regulation of the intermediate stopper mechanism, the slide door body once opened halfway. The vehicle does not turn back when it is not necessary, and the sliding door body does not pinch the passenger's luggage or the like trying to get off the vehicle. Therefore, the luggage and the like are not damaged.

According to the second aspect of the present invention, when the intermediate stopper mechanism is operating, the opening target value of the slide door body by the automatic opening / closing device is set within the opening restriction range by the intermediate stopper mechanism. Therefore, even if the slide door is opened by a switch operation, the slide door body usually stops at a position restricted by the intermediate stopper mechanism or at a position immediately before the position. For this reason, an overload state of the sliding door opening / closing motor does not occur, and the sliding door body that has been opened halfway is not returned even though it is not necessary.

Further, during the opening operation of the slide door body, even if the slide door body is restricted by the intermediate stopper mechanism due to overrun and the slide door opening / closing motor is overloaded, the opening degree of the slide door body is reduced. When it has already reached the vicinity of the opening target value, only the slide door body is stopped, and the operation of returning the slide door body to the fully closed position is not performed. Therefore, the slide door body once opened halfway is not required. Never turn back. Therefore, under the situation where the intermediate stopper mechanism is operating, the slide door body does not pinch the load or the like of the occupant trying to get off the vehicle.

According to the third aspect of the present invention, similarly to the first or second aspect of the present invention, the sliding door body which has been opened halfway is not necessary, but is not turned back. Luggage and the like are not trapped by the sliding door body. Therefore, the luggage and the like are not damaged. In addition, since the sensor that detects the rotation of the control lever determines that the intermediate stopper mechanism is operating and is in the restricted state, this determination can be made accurately and easily.

Further, according to the present invention, the switching of the intermediate stopper mechanism is promptly performed, and the halfway state does not occur. Further, since the intermediate stopper control mechanism is configured to indirectly determine the amount of lowering of the window glass by using the displacement of the lift arm, the size of the intermediate stopper control mechanism can be reduced.

According to the fourth aspect of the present invention, since the limit switch which is turned on / off by the other end of the control lever is used as a sensor for detecting the rotation of the control lever, the configuration can be simplified.

According to the fifth aspect of the present invention, since the limit switch is disposed in the space surrounded by the control lever, it is possible to prevent the limit switch from being damaged during assembly.
