Description

  The present invention relates to a sliding door device, and more particularly to a sliding door device configured to slide a sliding door by swinging a link arm.

  Conventionally, the following is known as a sliding door device for vehicles (for example, refer to patent documents 1). For example, Patent Document 1 discloses an example of a swing door applied to a vehicle such as a truck. In the example described in Patent Document 1, one end portion of the arm is rotatable by a support mechanism provided at the lower portion of the seat, and the other end portion of the arm is rotatable on the door. It is connected. Then, by swinging the arm with respect to the vehicle body, the door slides along the side of the truck.

  Incidentally, in the example described in Patent Document 1, for example, if a door motor is provided on the vehicle body side of the arm and the arm is swung by the door motor, the door can be electrically slid by the driving force of the door motor. Further, at this time, if the change in the current of the door motor is detected, it is possible to determine whether the foreign object is caught in the slide door based on the increase or decrease of the detected value.

Conventionally, the following is known as a technique for determining the insertion of a foreign object in this type of sliding door (see, for example, Patent Document 2). For example, Patent Document 2 discloses an example of a slide door structure in which a wire is provided on a slide door and the slide door is slid by winding the wire. In the example described in Patent Document 2, a drum for winding a wire is rotated by a motor, and by detecting a current change of the motor, it is determined whether a foreign object is caught in the slide door. ing.

  However, in a slide door structure in which the slide door is slid by swinging the link arm, for example, when a change in the current of the motor for swinging the link arm is detected to determine whether a foreign object is caught in the slide door Has the following problems.

  That is, generally just before the sliding door is closed, the reaction force of the weather strip that is interposed between the sliding door and the vehicle body acts on the sliding door. Therefore, when the reaction force from the weather strip acts on the sliding door, the threshold for detecting pinching immediately before the sliding door is closed is set high so that it is not judged that the foreign object is caught in the sliding door. Must be set. However, in such a case, the pinching detection accuracy is usually reduced immediately before the sliding door is closed (it is difficult to determine whether an obstacle is pinched or a reaction force from the weather strip). ).

  At this time, in the slide door structure in which the slide door is slid by the swing of the link arm, for example, the structure for judging the pinching of the foreign matter in the slide door by detecting the change in the rotational speed of the motor for swinging the link arm. Is also possible. However, in the case of this structure as well, as in the case of detecting the change in the current of the motor for swinging the link arm described above, it is necessary to set a high threshold for detecting pinching immediately before the sliding door is closed. Yes, in this case, the pinching detection accuracy just before the sliding door is closed is lowered.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a sliding door structure capable of improving the pinching detection accuracy immediately before the sliding door is closed.

In order to solve the above-mentioned problem, a sliding door device according to claim 1, wherein one end side is pivotally connected to a vehicle body, and the other end side of the link arm is pivotally attached. A sliding door that opens and closes a door opening provided in the vehicle body by swinging an arm; a pair of locking means that holds the sliding door on the vehicle body at two positions spaced apart in the width direction of the door; and the door of the sliding door Detection means for detecting the operating state of the pair of locking means accompanying the closing operation, and when the sliding door is moved to the half latch position during the door closing operation, the sliding door is fully closed from the half latch position. A closer for moving to a position, and after one of the pair of locking means is activated based on the detection result of the detecting means It has a role as a judging means for judging whether or not the other locking means is actuated within a predetermined time, and the other locking means is operated after one of the pair of locking means is actuated. And a control means for stopping or reversing the operation of the closer when the time until the operation exceeds the predetermined time .

  The door width direction in the present invention corresponds to, for example, the vehicle longitudinal direction when the slide door is provided on the side surface of the vehicle body, and the vehicle width when the slide door is provided on the back surface of the vehicle body. Corresponds to the direction.

  In the sliding door device according to claim 1, when the link arm whose one end side is rotatably connected to the vehicle body swings in a predetermined direction when the sliding door is in a position where the door opening is opened, the link arm A slide door that is pivotably connected to the other end of the slide slides in a direction to close the door opening. When the sliding door moves to a position where the door opening is closed, the sliding door is held on the vehicle body by a pair of locking means at two positions separated in the door width direction.

  At this time, the detection means detects the operating state of the pair of lock means accompanying the door closing operation of the slide door. Then, it is judged by the judging means whether or not the other locking means is actuated within a predetermined time after one of the pair of locking means is actuated.

  Here, when no foreign object is caught in the sliding door, after one of the pair of locking means is activated, the other locking means is within a predetermined time (this delay time is Due to manufacturing errors and link arm deformation). Therefore, when it is determined by the judging means that one of the pair of locking means is activated and the other locking means is actuated within a predetermined time, the foreign object is caught in the sliding door. It can be judged that it is not.

  On the other hand, when a foreign object is caught in the slide door, after one of the pair of locking means is activated, the other locking means is not activated and a predetermined time elapses. Therefore, if it is determined in the determination means that after one of the pair of lock means is activated, the other lock means is not activated within a predetermined time, the foreign object is caught in the slide door. Can be determined to have occurred.

  At this time, for example, even when the weather strip is interposed between the slide door and the vehicle body, the influence of the reaction force of the weather strip on the detection of the respective operating states of the pair of locking means is It becomes substantially equal (for example, the action of the pair of locking means is similarly delayed by the reaction force of the weather strip).

  Therefore, in the determination of the determination means, that is, in the determination of whether the other locking means has been operated within a predetermined time after one of the locking means has been activated, The influence of the reaction force of the weather strip on the detection of the respective operating states can be offset each other, and the influence of the reaction force of the weather strip is hardly exerted.

Thus, according to the slide door device of the first aspect, it is possible to determine whether or not the foreign object is caught in the slide door by eliminating the influence of the reaction force of the weather strip. Thereby, for example, even when a weather strip is interposed between the slide door and the vehicle body, it is possible to improve the pinch detection accuracy immediately before the slide door is closed.
In the sliding door device according to the first aspect, when the sliding door is moved to the half latch position during the door closing operation, the closer is operated, and the sliding door is moved from the half latch position to the fully closed position. . Thereby, the slide door moved to the half latch position can be automatically moved to the fully closed position.
Furthermore, in the sliding door device according to claim 1, when the time from when one of the pair of locking means is activated until the other locking means is activated exceeds a predetermined time, that is, When a foreign object is caught in the slide door, the operation of the closer is stopped or reversed by the control means. As a result, it is possible to reliably prevent foreign matter from being caught in the slide door.
In particular, as described above, when the closer is configured to be able to rotate the latch member of the locking means, it is possible to directly stop or reverse the latch member that is a pinching detection site. Therefore, the time lag from the detection of pinching to the stop or reversal of the latch member can be reduced, and it becomes possible to more reliably prevent the foreign object from being pinched in the slide door.

  The slide door device according to claim 2 is the slide door device according to claim 1, wherein each of the locking means is provided on a striker member fixed to the vehicle body, and is rotatably provided on the slide door. And a latch member rotatable while being engaged with the member, wherein the detecting means detects a rotational position of the latch member.

  In the sliding door device according to claim 2, when the sliding door moves to a position where the door opening is closed, each locking means is activated, that is, each latch member provided rotatably on the sliding door is fixed to the vehicle body. It rotates while engaging with each striker member, and is held by the vehicle body. At this time, when the latch member is in a predetermined rotational position in the engagement state with the striker member in each lock means, this state is detected by the detection means as the operation state of each lock means. Then, in the determination means, it is determined whether one of the pair of lock means is activated and the other lock means is activated within a predetermined time.

  Thus, in the sliding door device according to claim 2, each locking means includes a striker member fixed to the vehicle body and a latch member provided rotatably on the sliding door, and the operation of each locking means. The state is configured to be detected based on the rotational position of the latch member. Accordingly, since there is little time lag from the operation of the locking means to the detection of this operating state, it becomes possible to further improve the detection accuracy of the pinching immediately before the sliding door is closed.

The sliding door device according to claim 3 is the sliding door device according to claim 1 , wherein the closer rotates the latching member in a state where the latching member is engaged with the striker member, thereby half-latching the sliding door. It is characterized by moving from a position to a fully closed position.

In the sliding door device according to the third aspect , the closer is configured to be able to rotate the latch member. When the slide door is moved to the half latch position during the door closing operation, that is, when the slide door is in the half door state and the latch member is engaged with the striker member, the closer closes the latch member to a predetermined position. By rotating in the direction, the slide door can be moved from the half latch position to the fully closed position. Thus, according to the sliding door device of the fourth aspect, since the part of the function of the closer is configured to also serve as the locking means, the structure of the closer can be simplified (the striker member and The closer can be simplified as much as the latch member.

A sliding door device according to a fourth aspect is the sliding door device according to any one of the first to third aspects, wherein the sliding door can be slid by swinging the link arm. Drive means , and the control means, when the time from when one lock means of the pair of lock means is activated until the other lock means is activated exceeds the predetermined time, The operation of the drive means is stopped or reversed.

In the sliding door device according to claim 4 , when the time from when one of the pair of locking means operates until the other locking means exceeds a predetermined time, that is, sliding When a foreign object is caught in the door, the operation of the driving means capable of sliding the sliding door by swinging the link arm is stopped or reversed by the control means. Even in this way, it becomes possible to reliably prevent the foreign matter from being caught in the slide door.

  Further, when the operation of the drive means is configured to be reversed by the control means, a large retraction amount of the slide door with respect to the obstacle can be ensured. Thereby, the prevention effect of the foreign object pinching in a slide door becomes larger.

  As described above in detail, according to the present invention, for example, even when a weather strip is interposed between the slide door and the vehicle body, the pinching detection accuracy immediately before the slide door is closed is improved. It becomes possible.

  First, the configuration of the sliding door device 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

  FIG. 1 is a plan sectional view of a right side surface portion of a vehicle V to which a sliding door device 10 according to an embodiment of the present invention is applied. FIG. 2 is used for the sliding door device 10 according to an embodiment of the present invention. FIG. 3 is a perspective view of the lock mechanism 26, and FIG. 3 is an operation explanatory diagram of the lock mechanism 26 shown in FIG. In these figures, an arrow Fr, an arrow Out, and an arrow Up respectively indicate the vehicle front-rear direction front side, the vehicle width direction outer side, and the vehicle vertical direction upper side.

  In a vehicle to which a sliding door device 10 according to an embodiment of the present invention is applied, a door opening 12 is provided on the rear side surface of the vehicle body as shown in FIG. In this vehicle, the lower edge of the door opening 12 is a rocker portion 14, and one end of a pair of link arms 16 arranged in parallel in the front-rear direction of the vehicle is connected to the rocker portion 14 via a hinge base 18. Each is pivotably connected. The other ends of the pair of link arms 16 are connected to the slide door 20 via a door hinge 22 so as to be rotatable. The sliding door 20 is slid between a door fully closed position for closing the door opening 12 by swinging of the link arm 16 and a door fully opening position for opening the door opening 12 on the rear side in the vehicle longitudinal direction from the door opening 12. It is the composition which becomes.

  Further, as shown in FIG. 1, a door motor 24 as a driving means is provided at a fixed portion of the pair of link arms 16 connected to the rocker portion 14 with the rocker portion 14 of the link arm 16 on the rear side in the vehicle longitudinal direction. Is provided. Of the pair of link arms 16, the link arm 16 on the rear side in the vehicle front-rear direction is electrically swung by the door motor 24.

  When the sliding door 20 is in the door fully closed position for closing the door opening 12 as shown in FIG. 1, the sliding door 20 is locked at two positions on the both sides in the vehicle front-rear direction (two positions spaced apart in the door width direction). It is held on the vehicle body by a lock mechanism 26 as means. The lock mechanism 26 protrudes and is fixed to each pillar 28, 30, a base member 34 disposed on both sides in the vehicle front-rear direction inside the slide door 20, and the base member 34 is rotatable. And a latch member 36 disposed so as to be opposed to the striker member 32.

  In the present embodiment, the lock mechanisms 26 have a line-symmetric configuration. A more detailed structure of each lock mechanism 26 will be described with reference to FIG. 2 taking the front-side lock mechanism 26 as an example. The striker member 32 is configured in an arch shape, and is a rod that extends substantially in the vehicle front-rear direction. It has a portion 32A. The base member 34 is configured in an L shape in a plan view, and rotatably supports the latch member 36 on the side surface on the striker member 32 side via a rotation shaft member 38. The latch member 36 is formed in an engagement recess 36A (that is, the engagement recess 36A is formed at a position shifted in the radial direction from the rotary shaft member 38 so as to open radially outward and engage with the rod of the striker member 32). Thus, the entire latch member 36 is formed in a substantially U shape.

  The base member 34 of the lock mechanism 26 is provided with a pole 40 for restricting the rotation of the latch member 36 and bringing the lock mechanism 26 into a door lock state. That is, the pole 40 is rotatably fixed to the base member 34 via the rotating shaft member 42 and is connected to a door lock lever (not shown) provided on the slide door 20 via a connecting means such as a wire. . The pawl 40 is rotated by operating the door lock lever described above, and when the door lock lever is locked, the pawl 40 is in the rotation position indicated by the three-dot chain line in FIG. When the door lock lever is unlocked, the rotation position shown by the solid line in FIG. 3 is allowed and the latch member 36 is allowed to rotate.

  Further, as shown in FIG. 2, the base member 34 of the lock mechanism 26 includes a closer 44 for rotating the latch member 36 and a rotation position of the latch member 36 (half latch position; two-dot chain line in FIG. 3). And a rotational position detection sensor 46 as a detecting means capable of detecting the rotational position indicated by.

  The closer 44 is connected to the latch member 36 via a rotary shaft member 38 and has a motor (not shown) for rotating the latch member 36 via the rotary shaft member 38 therein. As will be described in detail later, the closer 44 is configured to rotate the latch member 36 while being engaged with the striker member 32 as shown in FIG. 3 by operating the motor just before the sliding door 20 is closed. .

  In FIG. 3, a state in which the striker member 32 starts to be engaged with the latch member 36 in accordance with the door closing operation of the slide door 20 is indicated by a solid line. From this state, the latch member 36 is engaged with the striker member 32. A state in which the slide door 20 is half-latched by rotating in the combined state is shown by a two-dot chain line. From this state, the latch member 36 further rotates and slides with the striker member 32 engaged. A state where the door 20 is fully latched (fully closed state) is indicated by a three-dot chain line. FIG. 3 shows a state in which the striker member 32 is moved relative to the latch member 36 in accordance with the door closing operation of the slide door 20.

  Further, the rotation position detection sensor 46 shown in FIG. 2 outputs a half latch detection signal when the latch member 36 reaches the above-mentioned half latch position (rotation position indicated by a two-dot chain line in FIG. 3). It is configured.

  The door control ECU 48 shown in FIG. 1 is output from a door closing operation signal output from a door closing operation switch (not shown) and a rotational position detection sensor 46 (see FIG. 2) provided in each lock mechanism 26. Signals are input, and the operations of the door motor 24 and the closer 44 described above are controlled based on these signals. Details of the operation of the door control ECU 48 will be described below.

  Next, operation | movement of the sliding door apparatus 10 which concerns on one Embodiment of this invention is demonstrated.

(Door closing operation under normal conditions)
When the door control ECU 48 detects a door closing operation signal output from a door closing operation switch (not shown) when the slide door 20 is in a position where the door opening 12 is opened, the processing of the program shown in the flowchart of FIG. To start. When the door control ECU 48 starts the processing of the program shown in the flowchart of FIG. 4, first, the door motor 24 is operated (step S1). As a result, the link arm 16 on the rear side in the vehicle front-rear direction of the pair of link arms 16 is swung by the door motor 24, and the sliding door 20 is slid in the direction of closing the door opening 12 by the swinging of the link arm 16.

  In addition, when the door control ECU 48 operates the door motor 24 as described above, the door control ECU 48 detects an output signal from the rotational position detection sensor 46 of each lock mechanism 26 (step S2). Whether or not a half latch detection signal is output is determined (step S3). When the door control ECU 48 determines that no half-latch detection signal is output from any of the rotational position detection sensors 46 (step S3: NO), the door control ECU 48 returns to the process of step S1 described above and returns to the door motor 24. Continue to operate.

  On the other hand, when the sliding door 20 slides in the closing direction of the door opening 12 and closes to close the door opening 12, the striker member 32 is moved into the sliding door 20 through the notches 50 and 52 formed in the sliding door 20. The engaging recess 36A of the latch member 36 comes into contact with the rod portion 32A of the striker member 32 (see the solid line in FIG. 3). Further, when the slide door 20 slides in the direction in which the door opening 12 is closed from this state, the latch member 36 is rotated by the striker member 32 to reach the half latch position (see the two-dot chain line in FIG. 3). When the latch member 36 reaches the half latch position, the rotational position detection sensor 46 outputs a half latch detection signal to the door control ECU 48 (the signal level is changed from LOW to HIGH; see FIG. 5A).

  Strictly speaking, at this time, for example, due to the manufacturing error of the slide door 20 or the deformation of the link arm 16, the half latch from the other rotational position detection sensor 46 to the one rotational position detection sensor 46. A slight delay (variation) Δt occurs in the output of the detection signal (in the example of FIG. 5A, a delay (variation) Δt occurs in the output of the half latch detection signal from the rotational position detection sensor 46 on the rear side. ing).

  As described above, when the half latch detection signal is output from any one of the rotational position detection sensors 46, the door control ECU 48 repeats the above-described processing of Step S1 to Step S3, It is determined that the half latch detection signal is output from any of the detection sensors 46 (step S3: YES). Subsequently, the door control ECU 48 determines which rotational position detection sensor 46 previously outputs the half latch detection signal (step S4).

  When the door control ECU 48 determines that the half-latch detection signal has been output first from the rear rotational position detection sensor 46 in the process of step S4 (step S4: rear lock), the front-side rotation is performed. An output signal from the position detection sensor 46 is detected (step S5). Similarly, when the door control ECU 48 determines in the process of step S4 that the half-latch detection signal has been output first from the front-side rotational position detection sensor 46 (step S4: front lock), the door-side ECU 48 An output signal from the rotational position detection sensor 46 is detected (step S6). At this time, for example, an output signal from the other rotational position detection sensor 46 remaining when a predetermined time ts shown in FIG. 5A elapses is detected.

  Subsequently, the door control ECU 48 determines whether or not a half latch detection signal is output from the remaining rotational position detection sensor 46 within a predetermined time ts shown in FIG. Step S7, Step S8). The specified time ts is set to a time slightly longer than the delay (variation) Δt caused by these in consideration of the manufacturing error of the slide door 20, the deformation of the link arm 16, and the like.

  When the door control ECU 48 determines that the half-latch detection signal is output from the remaining rotational position detection sensor 46 within the predetermined time ts shown in FIG. 5 (step S7: YES, step In S8: YES, the door motor 24 is stopped by stopping (OFF) the output of the control signal to the door motor 24 as shown in FIG. 5A (step S9). As a result, the slide door 20 stops at the half latch position.

  Further, subsequently, the door control ECU 48 operates the closer 44 by outputting a control signal (closing direction) to the closer 44 as shown in FIG. 5A (step S10). As a result, the latch member 36 is rotated from the half latch position to the full latch position (rotation position indicated by a three-dot chain line in FIG. 3) in a state where the latch member 36 is engaged with the striker member 32. As shown in FIG. It is held in the fully closed position. Then, the door control ECU 48 ends the series of program processing.

(Operation when the foreign object 60 is caught in the front side portion of the sliding door 20)
On the other hand, as described above, when the slide door 20 is slid in the direction of closing the door opening 12 by the swinging of the link arm 16, for example, as shown in FIG. When the foreign object 60 is sandwiched between the front side portion of the slide door 20 and the vehicle body just before closing, the operation is as follows.

  That is, for example, as shown in FIG. 6A, when the foreign object 60 is sandwiched between the front side portion of the slide door 20 and the vehicle body just before the slide door 20 is completely closed, the front side lock is caused. The mechanism 26 cannot be locked, and only the rear locking mechanism 26 is locked. In this case, the half latch detection signal is output only from the rear side rotational position detection sensor 46 without outputting the half latch detection signal from the front side rotational position detection sensor 46 (see FIG. 5B). .

  Accordingly, the door control ECU 48 has a role as a determination means, and from the remaining rotational position detection sensor 46 remaining within the predetermined specified time ts shown in FIG. It is determined that the half latch detection signal has not been output (step S7: NO). Then, the door control ECU 48 stops the door motor 24 by stopping (OFF) the output of the control signal to the door motor 24 as shown in FIG. 5B (step S11).

  Subsequently, the door control ECU 48 outputs a release signal (opening direction) to the closer 44 as shown in FIG. 5B, thereby causing the closer 44 to reverse (door lock releasing operation) (step S12). As a result, the latch member 36 rotates from the fully latched position to the open position (the rotational position indicated by the solid line in FIG. 3) with the striker member 32 engaged, and the striker member 32 can be detached from the latch member 36. (See the state shown by the solid line in FIG. 3).

  Then, the door control ECU 48 reverses the door motor 24 by outputting a control signal (opening direction) for the reverse operation to the door motor 24 as shown in FIG. 5B (step S13). As a result, the slide door 20 slides in a direction to open the door opening 12. Subsequently, the door control ECU 48 determines whether or not the slide door 20 has reached the fully open position by detecting an output signal from a courtesy switch provided in the vehicle, for example (step S14). When it is determined whether or not has reached the fully open position (step S14: YES), the series of processes is terminated.

(Operation when the foreign object 60 is caught in the rear part of the slide door 20)
Further, as described above, when the slide door 20 slides in the direction of closing the door opening 12 by the swinging of the link arm 16, for example, as shown in FIG. When a foreign object 60 is sandwiched between the rear portion of the slide door 20 and the vehicle body, the following operation is performed.

  That is, for example, as shown in FIG. 6B, when the foreign object 60 is sandwiched between the rear side portion of the slide door 20 and the vehicle body just before the slide door 20 is completely closed, the rear side lock is caused. The mechanism 26 cannot be locked, and only the front-side lock mechanism 26 is locked. In this case, the half-latch detection signal is not output from the rear-side rotational position detection sensor 46, but is output only from the front-side rotational position detection sensor 46 (see FIG. 5C). .

  Therefore, the door control ECU 48 has a role as a determination means, and from the remaining rotational position detection sensor 46 remaining within the predetermined specified time ts shown in FIG. It is determined that the half latch detection signal has not been output (step S8: NO). Then, the door control ECU 48 stops the door motor 24 by stopping (OFF) the output of the control signal to the door motor 24 as shown in FIG. 5C (step S15).

  Subsequently, as shown in FIG. 5C, the door control ECU 48 outputs a release signal (opening direction) to the closer 44, thereby causing the closer 44 to reverse (door lock releasing operation) (step S16). As a result, the latch member 36 rotates from the fully latched position to the open position (the rotational position indicated by the solid line in FIG. 3) with the striker member 32 engaged, and the striker member 32 can be detached from the latch member 36. (See the state shown by the solid line in FIG. 3).

  When the foreign object 60 is sandwiched in the rear portion of the slide door 20, the door control ECU 48 ends the series of processes without rotating the door motor 24.

  Next, the operation and effect of the sliding door device 10 according to one embodiment of the present invention will be described.

  As described above in detail, in the slide door device 10 according to the embodiment of the present invention, the operating state of the pair of lock mechanisms 26 accompanying the door closing operation of the slide door 20, that is, the latch member 36 in each lock mechanism 26. The half latch position is detected by the rotational position detection sensor 46. Then, after one of the pair of lock mechanisms 26 is operated, it is determined whether or not the other is operated within a predetermined time ts.

  Here, when the foreign object 60 is not caught in the slide door 20, after one of the pair of lock mechanisms 26 is operated, the other is within a predetermined time ts (this delay time is the slide door). 20 due to manufacturing error or deformation of the link arm 16). Accordingly, when it is determined that one of the pair of lock mechanisms 26 is activated and the other is activated within a predetermined time ts, the foreign object 60 is not caught in the slide door 20. I can judge.

  On the other hand, when the foreign object 60 is caught in the slide door 20, after one of the pair of lock mechanisms 26 is activated, the other is not activated and a predetermined time ts elapses in advance. Accordingly, if it is determined that one of the pair of lock mechanisms 26 has not been operated within a predetermined time after one of the lock mechanisms 26 has been operated, it is determined that the foreign object 60 has been caught in the slide door 20. it can.

  Further, at this time, for example, even when the weather strip 54 is interposed between the slide door 20 and the vehicle body, the reaction of the weather strip 54 over the detection of the respective operation states of the pair of lock mechanisms 26 is achieved. The influence of the force is substantially equal (for example, the reaction force of the weather strip 54 delays the operation of each lock mechanism 26 in the same manner).

  Therefore, in determining whether one of the above-described pair of lock mechanisms 26 is activated and the other is activated within a predetermined time ts, the detection of the respective operation states of the lock mechanisms 26 is performed. The influence of the reaction force of the weather strip 54 can be offset each other, and the influence of the reaction force of the weather strip 54 is hardly affected.

  As described above, according to the slide door device 10 according to the embodiment of the present invention, it is possible to determine whether or not the foreign object 60 is caught in the slide door 20 by eliminating the influence of the reaction force of the weather strip 54. Accordingly, for example, even when the weather strip 54 is interposed between the slide door 20 and the vehicle body, it is possible to improve the pinching detection accuracy immediately before the slide door 20 is closed.

  Further, in the slide door device 10 according to the embodiment of the present invention, each lock mechanism 26 includes a striker member 32 fixed to the vehicle body, and a latch member 36 rotatably provided on the slide door 20. The operating state of each lock mechanism 26 is configured to be detected based on the rotational position of the latch member 36. Accordingly, since there is little time lag from the operation of the lock mechanism 26 to the detection of this operation state, it is possible to further improve the pinching detection accuracy immediately before the sliding door 20 is closed.

  In the slide door device 10 according to the embodiment of the present invention, the closer 44 rotates the latch member 36 in a predetermined direction so that the slide door 20 can be moved from the half latch position to the fully closed position. It has become. Therefore, a part of the function of the closer 44 is also used as the lock mechanism 26, so that the structure of the closer 44 can be simplified (the closer 44 is used as the striker member 32 and the latch member 36). Can be simplified).
