Description of the Invention [Technical Field] The present invention relates to a lock-up switch device that can be pivotally mounted with respect to a frame that can be reciprocally mounted to reciprocately move, and that can be stopped in a fully closed position. [Prior Art] In the related art, a lock switch device that can be reciprocally moved to the outer frame and that can be reciprocally moved to the outer frame, and which can be stopped at the fully closed position, is disclosed, for example, in Japanese Laid-Open Patent Publication No. 2000-142392. The sliding door switch device according to the second embodiment is well known. In the configuration of the patent document 1, the movable member of the linear motor for the switch drive that suspends the track moving body and the sliding door of the sliding door is connected to the sliding door of the sliding door by the two-piece sliding door mechanism. The structure is connected via a buffer body including a buffer spring. Further, while the movable member drives the movable member in the linear motor to move toward the closing direction, even if the sliding door reaches the fully closed position, the spring of the cushioning body can drive the movable member more extendedly. In this way, the pressing metal member disposed at the front end of the movable member causes the sliding collar device to slide against the push spring, and the descending driven collar causes the latch lock to simultaneously descend, so that the latch lock is locked to the rack gear. The hole in the rack of the mechanism, so that the stop of the sliding door in the fully closed position can be realized. In this configuration, the driving force of the linear motor is usually distributed by the buffer spring of the buffer body for the switching drive of the sliding door. When the sliding door reaches the fully closed position, the driving force of the linear motor is distributed to the sliding collar device. 5- 1357459 Γ1ΓΕΤΙ

The year and month p repair (more) is replacing the stop of the I ---- latch lock. That is, the driving force of a single linear motor (actuator) is formed by both the switching drive and the locking operation of the sliding door, and has an advantage that the configuration can be simplified. SUMMARY OF THE INVENTION However, in the above-described Patent Document 1, a rack is disposed above and below the pinion gear, and each rack is coupled to a pair of left and right sliding doors, thereby opening and closing the sliding door by means of the switch. The constraint of one of the racks and the other of the sliding doors can be constrained via the pinion. Therefore, when the pinion or rack is damaged, the other door lock will be released. In addition, the pinion gear or the rack may be strong, but there is a problem that the installation space is increased in size and cost, etc. Further, the above-described Patent Document 1 is configured such that the switch driving of the sliding door and the pushing of the sliding collar are promoted. The buffer body of the driving force mechanism of the distributed linear motor is configured to slide together with the sliding door. Therefore, while the overall configuration is complicated, it is necessary to secure a space for the movable stroke amount of the cushion body, and the simplification and small configuration of the sliding door lock device cannot be realized. Further, in the fully closed position of the sliding door, in order to stretch the buffer spring of the cushioning body to push the structure of the sliding pinion device, for example, a load such as a wind pressure is applied to the door before the moment of the fully closed position (relative to the closing of the sliding door) In the case of resistance), the extension of the buffer spring is caused before the sliding door reaches the fully closed position. As a result, the pushing metal member at the front end of the movable member pushes the sliding collar device at a premature stage, failing to match the position of the bolt lock and the hole of the rack, so that the latch lock is lowered, and the latch lock or the hole portion may be caused. Broken or sliding door at the full -6 - 1357459 100. 10· 2 i~--1

The year of the month (more) is replacing the member ί __J before the stage of closing the position (on state) is constrained. In addition, when the sliding door is closed, the linear motor loses the driving force due to the failure of the linear motor or the power supply cannot be supplied due to the power failure, and the movable member and the push-out metal member are swept toward the sliding by the buffer spring. While the wheel is being pulled in the disengaging direction, the sliding collar device is also reset by the return spring, and together with the driven collar, the latch lock is raised to release the stop. This means that the shutdown is released when there is no fault or the power supply is not available. This is used as a side door of a rail vehicle, which means that the door will be opened before the vehicle stops, which is not ideal for safety. In addition, in the case where the above-described strong buffer spring is used to prevent the premature drop of the latch lock, the driving force of the linear motor is lost in the unlocking direction due to the inability to supply the power supply or the like. The force will also increase, thus increasing the unexpected release of the lock. That is to say, the above two problems have contradictory relationships, and therefore, it has not been possible to propose a structure that can simultaneously satisfy the problems of both parties. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a simple and small-sized interlocking switch device capable of reliably stopping a split sliding door while performing a sliding operation of a single actuator, that is, a closing and stopping. It is an interlocking switch device that can switch the movable sliding door relative to the outer frame to be reciprocally mounted and can be stopped at the fully closed position. Further, the lock device according to the present invention has the following features in order to achieve the above object. That is, the attached switch device of the present invention has the following features, which can be combined individually or appropriately. 1 1357459 of the attached switch device according to the present invention for achieving the above object

a rack gear mechanism comprising: a pair of racks of a pair of sliding doors that are reciprocally movable relative to the outer frame; and a pinion gear that engages the pair of racks; An actuator for a switch driving source; and a locking mechanism disposed on the outer frame to respectively restrict movement of the locking members fixed to the sliding doors of the pair of sliding doors, thereby stopping the pair of sliding doors in a fully closed position a switching mechanism for switching between a locked state and a unlocked state of the lock mechanism; and an input unit for inputting a driving force of the actuator; and a first output unit for outputting the driving force to the pinion; The switching mechanism outputs a planetary gear mechanism of the second output portion of the driving force, and when the sliding door position is at the fully closed position, the driving force is output from the second output portion with respect to the switching mechanism, and the switching mechanism has the following The second output unit is driven to move, and the switching member for the locked state and the unlocked state of the lock mechanism is switched, and the lock mechanism includes: a link mechanism in which the movement of the switching member is deformable into a linear state or a curved state, and a link holding mechanism capable of holding the link mechanism, wherein the lock mechanism maintains the link when the sliding door is outside the fully closed position The mechanism maintains the link mechanism in a curved state to prevent movement of the switching member, and the locking mechanism deforms the link mechanism into a linear state when the sliding door is in the fully closed position, thereby allowing movement of the switching member And constraining the movement of the locking member fixed to the above sliding door. According to this configuration, the movement of the pair of sliding members respectively fixed to the locking members of the respective sliding doors is restricted by the locking mechanism, so that the pair of sliding doors can be independently stopped. Therefore, even if the rack and pinion mechanism fails, the -8 - 1357459 iUD. iu. z i ! is replaced by the 丨 ______! occasion, and the locked state of the sliding movement of both sides can be maintained. On the other hand, when the rack and pinion mechanism is in a normal function, even if the stop of one of the sliding doors is released due to a failure or the like, since the one of the sliding doors is coupled to the other sliding door by the rack and pinion mechanism, the other is The sliding of the sliding door can be maintained in a locked state as long as it is effective. Therefore, the stop of the split sliding door can be made more sure. Further, in this configuration, the power of the actuator is distributed via the planetary gear mechanism. One is a pinion that drives the rack and pinion mechanism, and the other is a drive switching mechanism. Therefore, since the configuration for power transmission (distribution) from the actuator is housed in a small space, it is possible to simplify the structure and provide a small lock switch device. Further, the distribution of the driving force from the actuator is not performed by the use of the planetary gear mechanism as in the cushion spring of Patent Document 1, and therefore the driving force is lost even in the state of stopping the sliding door in the closed position. In this case, the force in the unlocking direction is not applied to the switching mechanism or the like, and the accidental unlocking can be prevented. Further, when the sliding door position is outside the fully closed position, the movement of the switching member is prevented, so that the sliding operation is performed after the sliding door has indeed reached the fully closed position. That is, it is possible to prevent the locking operation from being performed at a premature time when the sliding door is driven in the closing direction, and the locking mechanism is broken or the sliding door is restrained before being fully closed. Moreover, in the fully closed position, the movement of the sliding door can be stopped due to the linear state of the link mechanism, and the link mechanism is kept in the bent state by the link holding mechanism outside the fully closed position. Therefore, after the sliding door reaches the fully closed position, -9 - 1357459 100ΓΠΓ2Ϊ i Year release (more) The replacement page can be locked. As described above, the locking mechanism can be miniaturized by driving with a link mechanism, and can be mechanically driven to achieve stable driving. Further, a second feature of the lock switch device according to the present invention is that the lock mechanism member is configured to extend in a vertical direction and is fixed to a stopper pin of the sliding door, and the link holding mechanism is rotatably provided in the connection. In the vicinity of both end portions of the lever mechanism, the first engaging portion that engages with the stopper pin at the fully closed position and the second engaging portion that engages with the end portion of the link mechanism in the straight state at the fully closed position The engaging member is configured to prevent the movement of the link mechanism from moving in a straight state when the sliding door is at a position other than the fully closed position, thereby preventing the movement of the switching member, and simultaneously closing the sliding door When the direction moves, the stopper pin acts, and the end portion of the link mechanism is rotated to a position where it engages with the second engagement portion, thereby allowing the movement of the switching member. According to this configuration, in the fully closed position The engaging member is formed to engage with the stopper pin. Further, the link mechanism extends in a straight line state, thereby engaging with the end portion of the link mechanism to restrict the rotation thereof. Thereby, the stopper pin restrains its movement in a state of being engaged with the engaging member. As described above, the movement of the link mechanism toward the straight state can be prevented by the engaging member outside the fully closed position, and the movement of the stopper pin can be restrained at the fully closed position. Therefore, the number of parts required to form the locking mechanism can be reduced, and a smaller locking mechanism can be formed. Further, a third feature of the lock switch device according to the present invention is that the switching member is slidable in one direction with respect to the lock mechanism, and has a slide slider having a slit portion having a curved bottom surface. 10 - 1357459 § · W _ 2 Factory: | 曰月曰修(更) is replacing 1丨____} ........... '* The link mechanism is on the underside of the stop slider Simultaneously with the parallel in-plane operation, the coupling pin provided at a connection point is inserted into the slit portion, and as the stopper slider moves, the coupling pin moves along the slit portion so that the link mechanism is in a straight line Deformation between state and bending state. According to this configuration, there is no other member between the stopper slider and the link mechanism, and the movement of the stopper slider in one direction can deform the link mechanism between the straight state and the curved state. Therefore, the setting space of the locking mechanism can be reduced. Further, a fourth feature of the lock switch device according to the present invention is that the link mechanism can be deformed into a straight state or a curved state in a horizontal plane. According to this configuration, when the sliding door reaches the fully closed position, the switching mechanism is driven to deform the link mechanism into a straight line in the horizontal plane, and the sliding door can be stopped. As described above, the lock mechanism is such that the link mechanism that operates in the water level causes the slide door to be locked, so that the installation space of the lock mechanism in the height direction can be reduced. Further, a fifth feature of the lock switch device according to the present invention is that the link mechanism includes a link portion that is rotatably fixed to the outer frame, and the link mechanism is restricted by a linear guide groove provided in the outer frame. According to this configuration, the movement of the end portion is such that the link portion of the link mechanism is rotatably fixed to the outer frame. The position of the link mechanism can be fixed to the outer frame without hindering the action of the link mechanism. Further, the movement of the end portion of the link mechanism is restricted to the straight line by the guide groove of the outer frame, and the link mechanism which is deformed between the straight state and the curved state can be simply configured. -11 - 1357459

In addition, the sixth feature of the lock switch device according to the present invention is that the lock mechanism is formed by a stopper pin that is vertically extended and fixed to the sliding door, and the lock mechanism is further provided at a horizontal plane. The inner portion is rotatably provided in the vicinity of the end portion of the link mechanism, and has a first engaging portion that engages with the stopper pin at the fully closed position, and an end portion of the link mechanism that is in the fully closed position and the linear state. According to this configuration, the stopper pin extends in the vertical direction from the sliding door, and the locking mechanism that operates in the horizontal plane is easily engaged with the stopper pin. Also, in the fully closed position The end of the link mechanism in the straight state restrains the rotation of the engaging member, and the movement of the stopper pin can be restrained, so that the link mechanism can cause the extending direction of the straight state to form any direction that can restrain the rotation of the engaging member. Thus, for example, in the locked state, it is easy to design such that the force of the link mechanism from the linear state to the curved state does not act from the engaging member, and can be more surely protected. According to a seventh aspect of the present invention, in the lock switch device, the switching mechanism includes a switching member that is movable in a horizontal plane as the second output unit is driven, and is set in accordance with movement of the switching member. The link pin of the link mechanism is moved, and the link mechanism is deformable between a linear state and a curved state. According to this configuration, since the switching member can move in a horizontal plane, the installation space in the height direction can be reduced. Further, the switching member is a simple configuration that can change the state of the link mechanism by using the connecting pin that constitutes the link mechanism, and constitutes a small number of parts. Further, the eighth feature of the lock switch device according to the present invention is the above-described cut -12 - 1357459 ,~ι〇πσ.Ίπ---------------_

The replacement of the I-change mechanism is a stop slider having a slit portion having a curved bottom surface while the second output portion is slidably movable in one direction in the horizontal plane, and is set. a coupling pin at a connection point of one of the link mechanisms is inserted into the slit portion, and the connecting pin provided at a connection point of the link mechanism moves along the slit along the movement of the stopper slider to enable the connection The rod mechanism is deformed between a straight state and a bent state. According to this configuration, the movement of the link mechanism can be restricted by using the slit of the bottom surface of the stopper slider slidably movable in the horizontal plane. Further, since the slit has a curved shape, it is possible to easily realize a configuration in which the coupling pin is introduced in a direction different from the moving direction of the stopper slider. Further, a ninth feature of the lock switch device according to the present invention includes: a pair of racks respectively attached to a pair of sliding doors that are reciprocable with respect to the outer frame, and a small pair of the pair of racks a rack and pinion mechanism constituted by a gear; an actuator as a switch drive source of the sliding door; and an outer frame provided to constrain movement of the locking members fixed to the sliding doors of the pair of sliding doors, respectively a locking mechanism for stopping the pair of sliding doors in the fully closed position; a switching mechanism for switching the locked state and the unlocked state of the locking mechanism; and an input portion for inputting a driving force of the actuator, for the pinion a first output unit that outputs the driving force, a planetary gear mechanism that can output the driving force to the second output unit, an elastic member that contacts the second output unit, and an outer frame that is provided in the outer frame In the closing operation, when the amount of deformation of the elastic member reaches a predetermined amount of deformation, the collision detecting means for driving the actuator is stopped, and the sliding door position is fully closed. In the case of the above-mentioned second output unit, the above-mentioned driving force is outputted to the above-mentioned 13-13357459 100. ~. 21 ~--year 3 repair (more) positive replacement page switching mechanism, and the second output portion may be for the elastic member The driving force of the above actuator is output. According to this configuration, when the sliding operation of the sliding door is performed (when the sliding door is moved from the fully open position toward the fully closed position), when the running resistance of the sliding door is smaller than the predetermined running resistance, the rotation of the second output portion is the elastic force of the elastic member. Therefore, the driving force of the actuator is transmitted from the first output unit to the pinion gear, and the closing operation of the sliding door is performed. When the passenger is clamped during the closing operation of the sliding door or when the sliding door collides with the passenger, the pulling is performed. The door has a function of a force equal to or higher than the normal running resistance. When the predetermined running resistance is exceeded, that is, the elastic force of the elastic member is resisted, the second output portion is rotated to elastically deform the elastic member. When the amount of elastic deformation reaches a predetermined amount, the driving of the actuator is stopped by the collision detecting means. Since the collision detecting means is provided on the outer frame in the same manner as the actuator, there is no complicated wiring, and it is possible to detect the door closing and collision of the sliding door closing operation. Further, in this configuration, collision detection can be performed regardless of the acceleration and deceleration of the sliding door, and collision detection can be performed in the entire area of the sliding door movement range. Further, a tenth feature of the lock switch device according to the present invention is that the elastic member is disposed between the second output portion and the switching member. According to this configuration, by the output from the second output unit, the switching member can be driven to switch the locking mechanism while exerting a force on the elastic member. Therefore, for example, when the elastic member is provided at another position, the driving force from the second output portion when the locking mechanism is switched is assigned to the elastic member and the switching member provided at the other position, but the second output unit and the switching are performed. The elastic member is disposed between the members, and is applied to the elastic member 14-1357459 ΐόπρχ^τΤΤΓ: —::1 if- Η曰 repair (more) the stop sound acts on the switching member at the same time, thereby effectively performing collision detection and Further, the first aspect of the lock switch device according to the present invention is that the collision detecting means detects a limit switch for stopping the driving of the actuator when the corner of the second output portion is formed at a predetermined rotation angle or more. According to this configuration, the rotation of the second output unit that rotates in response to the deformation of the elastic member is stopped by the limit switch to stop the driving of the actuator. Therefore, the collision detecting means can be configured by a simple configuration. The twelfth feature of the lock switch device is that the elastic member is provided so as to be flat with respect to the running resistance when the sliding door is normally closed. According to this configuration, the time during which the closing operation is normally performed is the time when the force that hinders the sliding operation does not act from the outside, and the elastic force that is balanced with the running resistance during the normal closing operation is the second by the elastic member. The output portion acts to form an elastic force that is smaller than the elastic member. That is, the elastic member is provided in a state in which the elastic member can be easily deformed. Thereby, the increase in the running resistance of the sliding door makes the deformation of the elastic member easy, so that it can be made higher. In addition, the impact of the sliding door on the conflicting object can be significantly alleviated at this time.

The door 1 for a vehicle shown in Fig. 1 is a door that can be used as a switch to form a side wall opening of a railway vehicle or the like, and has a pair of left and right sliding doors 11对. The two sliding doors 11Α and 11Β are provided to be reciprocally movable along the horizontally disposed guide rails 2 above the opening. More specifically, the upper edges of the sliding doors 11Α and 11Β are fixed to each other. The frame pulleys 4 are supported by the axles 3Α and 3Β, and the respective hangers 3Α and 3Β are freely rotatable. The door pulley 4 is configured to roll on the guide rail 2. Further, the vehicle door opening and closing door 1 is opened and closed by the lock switch device according to an embodiment of the present invention, and an automatic stop is formed so as not to be inadvertently opened in the closed state. The door of a vehicle such as a railway vehicle is extremely dangerous when it is open during walking, and therefore it is required to be surely pre-stopped to prevent unintentional opening during walking. Hereinafter, it will be described in detail. A plate-shaped substrate 5 is fixed to an upper portion of the side wall (outer frame) of the vehicle (above the opening), and the rack holder 6 fixed to the substrate 5 supports two racks 7 and 7Β.

Further, the base body 5 supports the planetary gear mechanism 20 (see Fig. 4). The planetary gear mechanism 20 has a freely supported sun gear 21 (input portion): a plurality of sliding positions are provided at the same time as the center g, and the upper portion of the swivel ground is held by 1 3 A and fixed at one end.

While the three of the sun gear 2 1 , the internal gear 22 , and the carrier 23 are disposed on the same axis, the arrangement can be relatively freely rotated with respect to the other. Further, the axes of the above three are aligned with the axis of the pinion gear of the above-described rack and pinion mechanism 10. Further, the sun gear 21 is coupled to an output shaft of an electric motor (actuator) of a direct drive type which can be rotated in the forward and reverse directions. Further, it may be connected via an appropriate speed reduction mechanism. The main body portion of the electric motor is fixed relative to the side wall of the vehicle. Further, the internal gear 22 is coupled to the pinion 9 of the above-described rack gear mechanism 10 via a bolt or the like (not shown). Further, the carrier 23 is coupled to the traction member 70 that pulls the lock slider 33 (switching member) for switching the lock state of the lock mechanism 60 and the lock release state. The pulling member 70 and the stopper slider 33 are provided to be movable in one direction along a guide shaft 72 extending in parallel with the racks 7A, 7B fixed to the base 5, and constitute a switching mechanism for the switchable locking mechanism. The pulling member 70 is formed in combination with the carrier 23 as the carrier 23 rotates to move in the above direction. A coil spring-shaped torsion limit spring 71 (elastic member) is disposed between the pulling portion 70 and the stopper slider 33. The torsion limit spring 71 applies an elastic force to the traction member 70 and the stopper slider 33 so that the traction member 70 is pressed against the stopper slider 33. That is, the torsion limit spring 71 is disposed to suppress relative movement of the traction member 70 with respect to the stopper slider 33. -18- 1357459 100. 2 1 Π 牟月曰修 (more) replacement yellow _________} The stopper slider 33 is provided at its upper end with a mounting portion that can slide with the guide shaft 72 at a predetermined interval in the moving direction. 33a and mounting portion 33b. Further, the front surface portion 33c extending downward from the mounting portion 33a and the mounting portion 33b and the bottom surface 33d formed by bending from the lower end of the front surface portion 33c toward the paper surface depth direction of FIG. 2 are formed (see FIG. 3, Figure 5, Figure 6). The traction member 70 is attached to the guide shaft 72 between the attachment portion 33a and the attachment portion 33b, and the torsion limit spring 71 is attached to the stop direction of the stopper slider 33 (arrows A1 in Figs. 3 and 5) The direction is hereinafter referred to as the stop axis A1) on the guide shaft 72 between the mounting portion 33b of the front end portion and the traction member 70. Since the torsion limit spring 71 is compressed in the axial direction (state after elastic deformation), the traction member 70 receives a biasing force toward the attachment portion 33a, and the end portion of the traction member 70 abuts against the attachment portion 33a. . Further, as shown in Figs. 3 and 5, the bottom surface portion 3 3 d of the stopper slider 33 has a slit 3 3 e (slit portion) having a curved shape. The slit portion 33e includes a first hole portion α extending in parallel with the moving direction, and a second hole portion formed continuously in the direction perpendicular to the moving direction in the first hole portion α. Next, the locking mechanism 60 of the switch door 1 will be described in detail. Fig. 7 is a partial cross-sectional schematic view showing the locking mechanism 60 in the locked state from the horizontal direction. Further, the planetary gear mechanism is located on the C1 side of Fig. 7, and the sliding door is located on the C2 side. The lock mechanism 60 is a mechanism that operates in a horizontal plane, and is positioned above the bottom surface portion 33d of the stopper slider 33 (on the side of the planetary gear mechanism 20), and is fixed to the base body 5 (see 2 -19-1357459).

—~i〇o. im -'-I Year 曰 repair (more) is replacing κ map, Figure 4). As shown in Figs. 3 and 5, the lock mechanism 60 is constituted by a link mechanism 61 that can be deformed in a straight state or a curved state in a horizontal plane and a link holding mechanism 65 that operates in a horizontal plane. The link mechanism 61 is formed by connecting three links 62a, 62b, and 62c. The center link 62a is rotatably fixed relative to the base 5 by a coupling pin 63a at its central portion in the longitudinal direction. One end of the center link 62a is coupled to one end of the link 62b via a coupling pin 63b. Further, the other end of the link 62a is coupled to one end of the link 62c via a guiding coupling pin 63c. The ends of the link 62b and the link 62c on the side opposite to the connection point of the link 62a are provided with pins 63d and 63e. As shown in FIGS. 3, 5, and 7, the pins 63d and 63e at the ends of the link mechanism 61 are respectively formed by inserting the end portions into the base 5 and forming a parallel straight line with the moving direction of the stopper slider 33. The guide grooves 80A, 80B (indicated by the two-dotted line in Figs. 3 and 5) are arranged to be movable along the guide grooves 80A, 80B. That is, the movement of the pins 63d, 63e is restricted by the guide grooves 80A, 80B, respectively. Further, the pins 63d and 63e are inserted into the guide grooves 80A, 80B on the side of the guide groove to form a roller (see Fig. 7), and friction between the guide grooves 80A and 80B is reduced, and the end portion can be smoothly moved. Further, the end portions of the pins 63d and 63e on the side of the stopper slider 33 are similarly formed with rollers (refer to Fig. 7), and the friction at the time of moving along the edge portions of the engaging members 66A and 66B, which will be described later, is reduced, and the locking operation can be stabilized. Further, the end portion of the guiding coupling pin 63c of the link mechanism 61 on the side of the stopper slider 33 is a roller formed and inserted into the slit 33e of the stopper slider 33. Therefore, the guide coupling pin -20- 1357459 Μ 1〇. 2 ί -----ι is restrained by the position of the stopper slider 33.

The date of the year is changed (3⁄4 is the position of the replacement page I 63c. Thereby, the link mechanism can switch the linear state or the curved state by the movement of the stopper slider 33. The link holding mechanism 65 is provided at the link mechanism 61 The pair of engaging members 66 A and 66B are symmetrical with respect to the link mechanism 61 (relative to the connecting pin 63c) in the vicinity of the both end portions, and the pair of engaging members are coupled to each other. Each of the engaging members 66A and 66B includes a first engaging portion 6 7A and 67B and a second engaging portion 68A and 68B which are formed in a concave shape at the peripheral portion thereof, and the engaging member 6 6A The rotary shafts 81A and 81B of the 66B are fixedly disposed with respect to the base body 5 (refer to Fig. 7). Further, the frame member 82 is fixed to the pair of rotary shafts 81a and 81B, and is rotatably fixed to the link mechanism. The coupling pin 63a for the center link 62a is supported by the frame member 82 (refer to Figs. 2 and 4). The link holding mechanism 65 is in a state where it is not subjected to an external force, and the engaging member 66A, 66B receive the force from the connection spring 69, and maintain the state shown in Fig. 3. At this time, the engaging members 66A and 66B restrict the movement of the link mechanism 61 in a straight line state by the outer edge portion (portion indicated by an arrow P2 in Fig. 3). As described above, the link mechanism 61 is engaged by the link mechanism 61. When the members 66A and 66B are held in a curved state, the stopper slider 33 restricts the movement toward the stopper direction A1 via the slit 33e and the guide coupling pin 63c. On the other hand, the engaging members 66A and 66B are opposed to each other by The movement of the stopper pins 14A and 14B fixed to the sliding doors 11A and 11B toward the closing direction (the direction indicated by the arrow B1 in Fig. 3, hereinafter referred to as the closing direction B1) acts on the edge of the first engaging portions 67A and 67B. (P1 in Figure 3 indicates -21 - 1357459

The portion is formed to be opposite to the urging force of the coupling spring 69 so that the second engaging portion 68A' 68B can be rotated in the direction approaching the link mechanism 61 (the direction indicated by the arrow R1 in Fig. 3). When the sliding doors 11A and 11B are in the fully closed position, as shown in Fig. 5, the stopper pins 14A and 14B are engaged with the first engaging portions 67A and 67B, and the positions of the second engaging portions 68A and 68B are formed. It is in a position to be engaged with the pins 63d and 63e at the end of the link mechanism 61. That is, the engaging members 66 A, 66B are moved to a state where the link mechanism 61 is not restrained from being deformed. At this time, when the stopper slider 33 is moved to the stop direction A1, the link mechanism 61 is moved from the curved state to the straight state by the movement of the guide coupling pin 63c along the slit 33e. Further, the pins 63d and 63e at the ends of the link mechanism 61 are engaged with the second engaging portions 68A and 68B of the engaging members 66A' to 66B. Thereby, the rotation of the engaging members 66A, 66B is restricted. Therefore, the movement of the stopper pins 14A, 14B with respect to the opening direction (the direction indicated by the arrow B2 in Fig. 3 and Fig. 5, hereinafter referred to as the opening direction) can be restricted by the first engaging portions 6 7A, 67B. Next, the switches and the locking operations for the sliding doors 11A and 11B will be described below with reference to Figs. 2 to 5 . Fig. 2 is a view showing a state in which the sliding doors 11A and 11B are moved in the closing direction B1, and the state in which the locking state of the lock mechanism 60 is released is displayed. In this state, the stopper pins 14A and 14B are located at positions away from the lock mechanism 60, and the lock mechanism 60 is held in the state shown in Fig. 3. In the lock release state, the link mechanism 61 is in a bent state. The engagement of the linear extension of the link mechanism 61 is restricted by the engagement members 66A, 66B. Thereby, the guide coupling pin 63c and the slit 33e -22- 1357459 ierim----] via the link mechanism 61 are replaced by the replacement of the page i, and the stop slider 33 is oriented toward the stop direction. A1's movement. Therefore, in the unlocked state of FIGS. 2 and 3, when the sun gear 21 of the planetary gear mechanism 20 is driven by the electric motor, it is transmitted to the pinion 9 via the internal gear 22, or via the planetary gear 24 The revolving and rotating gear 23 transmits the driving force so that the torsion limit spring 71 is deformed. Here, the torsion limit spring 71 balances the running resistance at the time of the normal closing operation of the sliding doors 11A and 11B, and acts on the pulling member 7 of the carrier 23 so as to suppress the predetermined elastic force which is rotated by the carrier of the planetary gear 24 relative to each other. Acting on the carrier 23. Therefore, when the sun gear 2 1 of the planetary gear mechanism 20 is moved by the electric motor during the normal closing operation, the planetary gear 24 does not revolve and rotates only, so that all driving forces of the sun gear are transmitted to the pinion gear via the internal gear 22 . 9. Switching of the gates 1 1 A, 1 1 B is formed. Further, even if the sliding doors 1 1 A and 1 1 B are moved to the closing direction B 1, the engaging members 66A and 66B of the locking mechanism 60 engaged with the stoppers 14A and 14B are coupled to the spring 69 to receive the elastic force, and are held in the third drawing. In the state indicated, the sliding doors 11A and 11B do not turn to the stop position (the position shown in Fig. 5) until they reach the fully closed position. Thereby, it is possible to prevent the movement of the lock mechanism 60 from being excessively advanced before the sliding door 11A 11B reaches the fully closed position. Therefore, the stopper pins 14A, 14B do not collide with the card members 66A, 66B moved to the stop position, causing the locking mechanism 60 to malfunction. In addition, when the sliding doors 1 1 A and 1 1 B are closed, the passengers are clamped, and the sliding resistance of the sliding doors 1 1 A and 1 1 B is significantly increased. Drive 2 1 Pulling the cause and action to make a match -23- 1357459

As will be described later, the carrier 23 is rotated in opposition to the biasing force of the torsion limit spring ,, and the rotation of the carrier 23 is detected such that the rotation of the electric motor is temporarily stopped, etc., and a predetermined safety operation can be performed. Next, as a result of driving the sun gear 21 in the direction in which the sliding doors 11A, 11B are closed, the sliding doors 11A, 11B are brought close to the fully closed position, and the stopper pins 14A, 14B fixed to the sliding doors 11A, 11B are formed and engaged. The members 66A, 66B abut (see Fig. 3). Further, when the center gear 21 is driven from this state such that the sliding doors 11A, 11B are moved further toward the closing direction B1, the stopper pins 14A, 14B act on the engaging members 66A, 66B, so that the engaging members 66A, 66B are in FIG. The arrow R1 direction continuously rotates and enters the recessed portions of the first engaging portions 67A and 67B. When the sliding doors 1 1 A and 1 lb reach the fully closed position, the engaging members 66A and 66B engage the stopper pins 14A and 14B with the first engaging portions 67A and 67B, and complete the second engaging portions 68A and 68B. The movement toward the stop position with respect to the pins 63d, 63e at the ends of the link mechanism 61. Thereby, the movement of the link mechanism 61 in the straight state is allowed. Therefore, when the sliding doors 11A and 11B are moved to the fully closed position, the stopper slider 33 connected via the guiding coupling pin 63c and the slit 33e can be formed with respect to the link mechanism 61 that is allowed to move in a straight state. The movement of the stop direction A1. As a result, the rotation of the carrier 23 coupled to the stopper slider 33 can be tolerated by the torsion limit spring 71 and the traction member 70. On the other hand, when the sliding doors 1 1 A and 1 1 B reach the fully closed position, they are prevented from moving in the closing direction B1. Therefore, the internal gear 22 - 24 - 1357459 connected to the sliding door 11A, 11B via the rack and pinion mechanism 10 can also be prevented. 100. 10. 2 ί ~~~~j Turn. Therefore, the driving force of the continuously rotating sun gear 21 is formed to convey the carrier 23, and the carrier 23 is rotated in the counterclockwise direction in FIG. 2, and the torsion limit spring 71 and the traction member 70 are formed to be stopped. The movement of the slider 33 in the stop direction Α1. Then, as the stopper slider 33 moves toward the stop direction Α1, the link mechanism 61 moves from the curved state (the state of Fig. 3) to the straight state (the state of Fig. 5). In the straight state, the rotation of the engaging members 66 A, 66 is restricted by the pins 63d, 63e of the link mechanism 61. Therefore, the movement of the stopper pins 14A, 14B of the first engaging portions 67A, 67B of the engaging members 66A; 66B is prevented from moving. Therefore, the movement of the sliding doors 11A, 11B is stopped via the stopper pins 14A, 14B. Further, the guide shaft 72 is provided with a stopper spring 73 such that the mounting portion 33a of the stopper slider 33 acts toward the stop direction A1, and the stop slider 33 positioned at the stop position is returned to the lock release position, which may be further It is indeed maintained in a locked state. As described above, the deformations of the fourth and fifth figures are shown in FIGS. 2 and 3, and the locking mechanism 60 is automatically locked after the movement of the sliding doors 1 1 A and 1 1 B toward the fully closed position. The doors 1 1 A, 1 1 B are locked in the closed state. Therefore, the central gear 21 of the planetary gear mechanism 20 is driven only by a single actuator, so that locking with the closing of the interlocking sliding doors 11A, 11B can be realized, and the driving configuration can be simplified. Further, in the locked state of FIGS. 4 and 5, the locking of the engaging members 66A, 66B can be restricted by the link mechanism 61, and the link mechanism 61 can be restrained by the stopper slider 33. The linear state is locked toward the deformation of the curved state, and a double lock is applied. In this way, for example, the vehicle may be in a state of being unable to supply power to the electric motor due to the stop of the vehicle - 25357535 'j Ι ° 1 Η Η 正 , , , , , , , , , , , , , , , , , , , , , , In this case, the opening of the sliding door η can be surely prevented by the above-described double locking, which means that even if the vehicle is powered off, it is possible to prevent the sliding door 11 风, the wind pressure, and the like from being inadvertently opened. Further, the switching from the above-described locked state to the locked state 1 1 A, 1 1 Β is open only by the above-described electric motor, and the middle 21 is driven in the opposite direction to the closing. In the locked state (and Fig. 5), the sliding doors 11A, 11B are the engaging members 66A and are locked to prevent the rotation of the internal gear 22. On the other hand, the movement of the stopper in the lock release direction (the direction indicated by the arrow Α 2 in Fig. 3 and Fig. 5, hereinafter referred to as the lock release direction Α 2) is suppressed only by the urging force of the stopper 73. That is, when the driving force against the stopper spring 73 is transmitted to the stopper slider 33, the stopper 33 can be formed in a state in which the lock releasing direction Α2 is moved. Therefore, the driving force of the sun gear 21 when the center gear 21 is driven in the opposite direction to the closing direction is transmitted to the carrier 23, and is pulled; | so that the stopper slider 33 resists the stop toward the unlocking direction Α2 ? The force moves. As the stopper slider 33 moves toward the lock release mechanism 2, the guide coupling pin 63c of the link mechanism moves from the first hole portion α to the second hole portion/3 along the opened edge portion, thereby causing the connection 6 1 Move from a straight state to a curved state. Therefore, the engagement of the second engagement portions 68, 68, of the engagement member 66's with the ends 63d, 63e of the link mechanism 61 is released. In this way, by connecting a pair of card output shafts (A, 1 1 B. This is the 1 1 B and the sliding force gear shown in Figure 4 6B bone block 33. The spring force force slider Locking shape, all_pieces 70 Single springs 73 Except for the direction of the seams 3 3e Rod mechanism 6 6 A, the pinning members of the parts 1357459 m-- Years of repair (more) are replacing the joint springs 69 that bought i 66A, 66B The elastic force of the engaging members 66A and 66B receives the force so that the first engaging portions 67A and 67B face outward (the side opposite to the link mechanism 61). That is, the engaging members 66A and 66B receive the force in the fifth figure R2. Therefore, the movement of the stopper pins 14A and 14B in the engaged state with respect to the second engagement portions 68A and 68B in the opening direction B2 is released, and the locking of the sliding doors 11A and 11B is released. The movement of the slider 33 in the unlocking direction A2 is restricted by the deformation limit of the stationary spring 73 at the position shown in Fig. 2. Further, the movement of the stopper slider 33 in the unlocking direction A2 is not limited to the stop motion. When the deformation limit of the spring 73 is restricted, the carrier 23 and the substrate may be restrained by abutting at a predetermined position. 5. Further, the lengths of the guide grooves 80A, 80B for inserting the pins 63d, 63e of the link mechanism 61 are appropriately set, and the movement of the pins 63d, 63e is restricted by the guide grooves 80A, 80B, so that the link can also be constrained The deformation of the mechanism 61 is used to restrain the movement of the stopper slider 33. As a result of the movement of the restraining stopper slider 33 in the unlocking direction A2, the driving force of the sun gear 21 of the planetary gear mechanism 20 is transmitted to the inside. Therefore, the sliding doors 1 1 A, 1 1 B are driven in the opening direction B2 via the rack gear mechanism 1 。 At this time, the engaging members 66A, 66B receive the rotation from the connecting spring 69 toward the unlocking position. The force in the direction (the force in the R2 direction of Fig. 5) does not constrain the movement of the stopper pins 14A, 14B fixed to the sliding doors 11A, 11B. Further, the stopper slider 33 is disposed inside the vehicle. Or a control lever (not shown) from an externally accessible position forms a structure in which a cable such as a cable (not shown) is connected to a -27- 1357459 JO. 10. 2 ί 1 year, whereby in an emergency, The person operates the lever such that the stop slider is in a direction to form a disengaged state In addition to unlocking, the sliding doors 11A, 11B can be manually opened. Further, a simple configuration can be formed, and the configuration in which the control lever is directly fixed to the stopper slider 33 can be formed. Next, in the sliding doors 11A, 11B When the closing operation is performed (when the sliding door is moved from the fully open position toward the fully closed position), when the running resistance of at least one of the sliding door 1 1 A and the sliding door 1 1 B is significantly increased, the eighth and ninth drawings are used. Description. For example, there is a case where a passenger is caught by the sliding door 1 1 A, 1 1 B or a case where one of the sliding doors collides with the passenger. Fig. 8 is a schematic diagram showing the state of the carrier 23 in the normal closing operation. Fig. 9 is a schematic view showing the state of the carrier 23 when the running resistance of the sliding door is increased during the closing operation. When the closing operation of the sliding doors 11A and 11B is normally performed, that is, when the sliding doors 1 1 A and 1 1 B are arbitrarily prevented from moving from the outside by the normal running resistance, the driving force of the sun gear 21 is as described above. It is transmitted to the side of the internal gear 22, and the sliding door 1 1 A, 1 1 B is driven by the rack gear mechanism 10 toward the closing direction B1. This is the reason why the movement of the stopper slider 33 is restrained when the sliding doors 11A, 11B are outside the fully closed position as described above. That is, in a state in which the movement of the stopper slider 33 is restricted, the traction member 70 coupled to the carrier 23 is acted upon by the torque limit spring 71 by a predetermined elastic force which can suppress the rotation of the carrier 23. In the present embodiment, in the state shown in Fig. 8, in order to balance the running resistance of the sliding doors 11A and 11B, the elastic force for suppressing the rotation of the carrier 23 is applied to the carrier via the pulling member 70. -28-1357459 1ΰ(). Ju. 21 '-~~j Years of the repair® is replacing the stomach | 23 on. That is, in the case of the closing operation, when the sliding doors 11A and 11B have a force equal to or higher than the normal running resistance, the position of the stopping slider 33 is in a fixed state, and the carrier 23 causes the torsion limit spring 71 to be elastically deformed. The side rotation moves toward the state shown in Fig. 9. Further, the permanent magnet 83 is fixed to the outer peripheral edge portion of the carrier 23, and the permanent magnet 83 is moved by the rotation of the carrier 23, thereby switching the detection switch 84 (collision detecting means, limit switch) attached to the base 5 side. Specifically, in the position of the carrier 23 when the sliding doors 11A and 11B are operated by the normal running resistance, the detecting switch 84 is in the OFF state. On the other hand, as the running resistance of the sliding doors 11A, 11B increases, the carrier 23 is rotated by a predetermined amount, whereby the detecting switch 84 is turned into an ON state (refer to Fig. 9). When the detection switch 84 is switched to the ON state, the driving of the electric motor is stopped and the driving of the electric motor is stopped. Thereby, when the sliding operation of the sliding doors 11A and 11B is performed, when the passenger is caught, or when the sliding door of the sliding sliding door collides with the passenger, the running resistance of the sliding door toward the closing direction B1 increases, and the electric power is stopped. The driving of the motor can alleviate the impact force on the passengers and the like that are caught by the sliding doors 11A, 11B. Further, when the detection switch 84 is in the ON state (when the detection is caught by the door or collided), it is not limited to the case where the stop of the electric motor drive is stopped, and the drive output of the electric motor can be controlled to be lowered. Further, when the sliding doors 11A and 11B are in the fully closed position, the driving of the electric motor is stopped or the driving of the electric motor is not stopped even if the driving is stopped. Therefore, the driving of the electric motor is not stopped when the above-described stopper slider 33 moves in the lock direction A1. -29- 1357459 TOO.' 10-21. In addition, for example, a lock state detecting sensor for detecting a locking state of the sliding door may be provided. After the detecting switch 84 sends a detection signal, the locking state detecting feeling is performed within a predetermined time. When the detector does not emit a detection signal, it is determined that the sliding door is caught by a collision or the like, and the electric motor is stopped. Further, for example, a deceleration sensor that detects the deceleration of the sliding door may be used. Therefore, when the moving speed of the sliding door is large during the closing operation, the detection switch 84 detects the rotation of the carrier, thereby judging the door clamping, the collision, etc., and on the other hand, the sliding door reaches the closing position and delays the sliding of the door. In the case of the moving speed, the door clamping, the collision, and the like can be detected by the deceleration sensor. As described above, the lock switch device of the present embodiment is provided to be reciprocally attached to the outer frame (wall surface) of the vehicle. a pair of racks 7A, 7B of a pair of sliding doors 11A, 11B of a split type and a rack pinion mechanism 10 formed by the pinion gear 9 of the pair of racks 7A, 7B; as the above sliding door 11A, 11B switch drive source electric motor; a base body 5 fixed to the outer frame of the vehicle, respectively, restricting movement of the stopper pins 14A, 14B fixed to the respective sliding doors of the pair of sliding doors 11A, 11B, thereby making the above one a locking mechanism 60 that locks the sliding doors 11A, 11B in the fully closed position; a locking slider 33 for locking the locking state and the unlocking state of the locking mechanism 60; and a sun gear 21 that inputs the driving force of the electric motor: have The output of the carrier for the driving force of the pinion gear 923 of the planetary gear mechanism 20. Further, when the sliding doors 11A and 11B are at the fully closed position, the carrier 23 is configured to output the driving force to the stopper slider 33. -30- 1357459 Ίπττυη " 1 year r repair (3⁄4 positive replacement page 丨 According to this configuration, the movement of the stopper pins 14A, 14B respectively fixed to the respective sliding doors of the pair of sliding doors 11A, 11B is a predetermined mechanism Since 60 is restrained, the pair of sliding doors 11A and 11B can be independently locked. Thereby, even if the rack gear mechanism 10 fails, the state in which the sliding doors 1 1 A and 1 1 B are locked can be maintained. On the other hand, when the rack and pinion mechanism 1 has a normal function, when the lock of one of the sliding doors 11A (11B) is released due to a failure or the like, the one of the sliding doors 11A (11B) passes through the rack and pinion mechanism 1〇. It is connected to other sliding doors (ΙΙΑ). Therefore, as long as the locking of the other sliding door IIB (IIA) is valid, the sliding door (ΙΙΒ) of one side can be maintained in a locked state. The lock of the split type sliding door 1 1 A, 1 1 B. Moreover, in this configuration, the power of the electric motor is distributed via the planetary gear mechanism 20, and on the other hand, the pinion gear 9 of the rack and pinion mechanism 1〇 is driven, and On the one hand, the stop slider 33 is driven. Therefore, Since the configuration for power transmission (distribution) of the electric motor is housed in a small space, it is possible to simplify the structure and provide a small lock switch device. In addition, the distribution of the drive force from the electric motor is not used as a patent. In the cushion spring of the document 1, the planetary gear mechanism 20 is used. Therefore, in the state where the sliding doors 11A and 11B are locked in the closed position, even if the electric motor loses the driving force due to a failure or the like, it is not necessary to apply the lock release to the stopper slider 33 or the like. The force in the direction A2 prevents accidental unlocking. Further, the lock switch device of the present embodiment has a stoppage that can be switched between the lock state and the lock release state of the lock mechanism 60 as the carrier 23 is driven to move. Block 33. Moreover, the above-mentioned locking mechanism 6 举 in the upper -31 - 1357459, H (more) positive replacement - when the sliding doors 11A, 11B are located outside the fully closed position, the movement of the stop slider 33 is prevented, When the sliding doors iiA and 11B are in the fully closed position, the stop slider 33 is allowed to move. According to this configuration, the sliding doors 1 1 A and 1 1 B are in the fully closed position. The movement of the stopper slider 33 is prevented from being stopped, so that the sliding operation is performed after the sliding doors liA, 11B have indeed reached the fully closed position. That is, the sliding of the sliding doors 1 1 a , 11B toward the closing direction B1 can be prevented from being premature. At the timing of the locking operation, the locking mechanism 60 is broken or the sliding doors 11A and 11B are restrained before being fully closed. In the attached switch device of the present embodiment, the locking mechanism 60 is provided with the following sliding mechanism. The movement of the block 33 is a link mechanism 161 that is deformable between a linear state and a curved state, and a link holding mechanism 65 that holds the link mechanism 61 in a curved state when the sliding door is outside the fully closed position. Further, when the sliding doors 11A, 11B are in the fully closed position, the locking mechanism 60 is deformed into a linear state, whereby the stopper pins 14A, 14B respectively fixed to the sliding doors 1 1 A, 1 1B can be restrained According to this configuration, the linear state of the link mechanism 61 in the fully closed position can lock the movement of the sliding doors 11A, 11B while maintaining the link mechanism 61 in the bent state by the holding mechanism 65 outside the fully closed position. Therefore, the sliding operation is performed after the sliding doors 1 1 A and 1 1 B reach the fully closed position. As described above, since the lock mechanism 60 can be formed to be small by driving using the link mechanism 61, stable driving can be realized due to mechanical driving. Further, the attachment switch device of the present embodiment has a vertical direction of 32 - 1357459

The fully closed position is constituted by a pair of engaging members 66 A and 66B of the second engaging portions 68A and 68B that are engaged with the end portions of the link mechanism 61 in the straight state. The engaging members 66A and 66B prevent the movement of the link mechanism 61 in a straight state when the sliding doors 11A and 11B are at positions other than the fully closed position, thereby preventing the movement of the stop slider 33 while When the sliding doors 11A and 11B move in the closing direction B1, the stopper pins 14A and 14B act to rotate the end portions of the link mechanism 61 to a position engageable with the second engaging portions 68A and 68B. Thereby, the movement of the above-described stopper slider 33 is allowed. According to this configuration, in the fully closed position, the engaging members 66A and 66B are engaged with the stopper pins 14A and 14B. Further, the link mechanism 61 is extended to a straight state, thereby engaging with the end portion of the link mechanism 61 to restrict its rotation. Thereby, the movement of the stopper pins 14A, 14B in engagement with the engaging members 66A, 66B is restricted. As described above, by the engaging members 66A, 66B, the movement of the link mechanism 61 toward the straight state is prevented in the fully closed position, and the movement of the stopper pins 14A, 14B can be restrained at the fully closed position. Therefore, the number of necessary parts can be reduced in order to form the locking mechanism 60, and a smaller locking mechanism 60 can be formed. Further, the lock switch device of the present embodiment can be configured to slidably move in the unidirectional direction with respect to the lock mechanism 60, and has a bottom slider curved shape of -33-1357459, and a stop slider 33 that replaces the slit 33e. The link mechanism 61 is operated in a plane parallel to the bottom surface of the stopper slider 33, and a guide coupling pin 63c provided at a connection point is inserted into the slit 33e, along with the stopper slider. When the movement of 33 is performed, the above-described guide coupling pin 63c moves along the slit 3 3 e, and the link mechanism 61 can be deformed between a linear state and a curved state. According to this configuration, there is no other member interposed between the stopper slider 33 and the link mechanism 61, and by the movement of the stopper slider 33 in one direction, the link mechanism 61 can be linearly and bent. Deformation between states. Therefore, the installation space of the lock mechanism 60 can be reduced. Further, the lock mechanism 60 is provided with a link mechanism 6 that is deformable between a straight state and a curved state in the water stroke surface. When the sliding doors 1 1 A and 1 1 B are in the fully closed position, the link mechanism 61 is deformed into The linear state can be engaged with the stopper pins 14A and 14B fixed to the sliding doors 11A and 11B to be in a locked state.

. . . V 1 , _.• The linear guide grooves 80A, 80B of the split body 5 constrain the movement of the pins 63d, 63e at the ends of the link mechanism 61. According to this configuration, the link 62a of the link mechanism 61 is rotatably fixed to the base 5, and the position of the link mechanism 61 with respect to the base 5 can be fixed without hindering the operation of the link mechanism 61. Further, the movement of the pins 63d and 63e at the ends of the link mechanism 61 can be restricted to the straight line by the guide grooves 8 OA and 80B of the base member 5, and the link mechanism which is deformed between the straight state and the bent state can be easily formed. 6 1. Further, the lock switch device of the present embodiment has the stopper pins 14A and 14B which are extended in the vertical direction and fixed to the sliding door. Further, the lock mechanism 60 is provided to be rotatable in the horizontal plane in the vicinity of the end portion of the link mechanism 61, and has the first engagement portions 67A and 67B that are engaged with the stopper pins 14A and 14B at the fully closed position, and at the fully closed position. The engaging members 66A and 66B of the second engaging portions 68A and 68B that are engaged with the pins 63d and 63e at the ends of the link mechanism 61 in the straight state. According to this configuration, the stopper pins 14A, 14B extend in the vertical direction from the sliding door ΙΙΒ '', and the locking mechanism 60 that operates in the horizontal plane can be easily engaged with the stopper pins 14, 14B. Further, in the fully closed position, the rotation of the engaging members 66A, 66B is restricted by the pins 63d, 63e at the ends of the link mechanism 61 in the straight state, and the movement of the stopper pins 14A, 14B can be restrained, so that the link mechanism 6 1 can be The direction extending toward the straight state forms an arbitrary direction that restricts the rotation of the engaging members 66 A, 66B.

The longitudinal and vertical directions of the movable guide grooves 8 OA and 8 OB of the 1357459 and 63e are supported by the engaging members 66A and 66B by the edges of the guide grooves 80A and 80B. That is, the force does not move the link mechanism 61 to the bent state, and the locked state can be more surely maintained. Further, at this time, the load on the links 62b and 62c is reduced, and the malfunction of the link mechanism 61 and the like can be suppressed. Further, the attachment switch device of the present invention has a stopper slider 33 which is movable in a horizontal plane as the carrier 23 is driven. Further, as the stopper slider 33 moves, the guide coupling pin 63c provided at the joint point of the link mechanism 61 moves along the slit 33e, and the link mechanism 61 can be deformed between the linear state and the curved state. According to this configuration, the movement of the link mechanism 61 can be restricted by the slit 33e of the bottom surface of the stopper slider 33 slidably movable in the horizontal plane. Further, since the slit 33e is formed in a curved shape, the guide connecting pin 63c can be easily guided in a direction different from the moving direction of the stopper slider 33.

Further, the lock switch device according to the present embodiment includes a case where the running resistance of the sliding doors 11A and 11B is smaller than a predetermined running resistance during the closing operation of the sliding door ΙΙΒ, and the predetermined rotation of the carrier 23 is suppressed. a torsion limit spring 71 that exerts an elastic force with respect to the carrier 23, and a biasing force of the torsion limit spring 71 when the above-described sliding door 11A, 11B is closed in the above-described base body 5, when the amount of deformation of the torsion limit spring 71 reaches a predetermined amount of deformation, -36-1357459 JO. 10. 2 1 ---------} Yearly repair (more) is replacing page j ^ »»|>丨_______ ...... || Stop the above electric motor drive The switch 84 is detected. Here, the carrier 23 can output the driving force of the electric motor with respect to the torsion limit spring 71. According to this configuration, when the sliding door 1 1 A, 1 1 B is closed (when the sliding door moves from the fully open position toward the fully closed position), the running resistance of the sliding doors 1 1 A, 1 1 B is less than the predetermined running resistance. In this case, the rotation of the carrier 23 is suppressed by the elastic force of the torsion limit spring 71, and the driving force of the electric motor is transmitted from the internal gear 22 to the pinion gear 9, and the closing operation of the sliding doors 11A and 11B is performed. When the passenger is caught in the closing operation of the sliding door ΙΙΒ, or when the sliding doors 11A and 11B collide with the passenger, the force equal to or higher than the normal running resistance acts on the sliding doors 11A and 11B, and when the predetermined running resistance is exceeded, The elastic force of the torsion limit spring 71 is reversed, and the carrier 23 is rotated to elastically deform the torsion limit spring 71. When the amount of elastic deformation reaches a predetermined amount, the driving of the electric motor is stopped by the detecting switch 84. Since the detection switch 84 is provided on the base body 5 fixed to the outer frame side as in the case of the electric motor, it is possible to detect the door closing or collision of the closing operation of the sliding doors 1 1 A and 1 1 B without complicated wiring. Further, in this configuration, collision detection can be performed not only during acceleration and deceleration of the sliding doors 11A and 11B, but also in all areas of the sliding range of the sliding doors 1 1 A and 1 1 B. Further, the attachment switch device of the present embodiment has a stopper slider 33 that can switch the lock state and the lock release state of the lock mechanism by movement. Further, the torsion limit spring 71 is disposed between the carrier 23 and the stopper slider 33.

WTT~~~~ The switch of the crossover (more) soil mechanism 60 on the day of the month. Therefore, for example, when the torque limit spring 71 is disposed at another position, the driving force of the carrier 23 from the switching of the lock mechanism 60 is distributed to the torque limit spring 71 and the stopper slider 33 provided at the other positions. Therefore, a small force β is formed, respectively. However, as shown in the present embodiment, a torque limit spring 71 is provided between the carrier 23 and the stopper slider 33, and the force applied to the torque limit spring 71 is connected in series to the stopper slider 33. Function, can effectively carry out conflict detection and locking action. Further, in the lock switch device of the present embodiment, the detection switch 84 is configured to detect a rotation angle of the carrier 23 to form a predetermined rotation angle or more and to stop the limit switch of the electric motor drive. According to this configuration, the driving of the electric motor is stopped by the limit switch detecting the rotation angle of the carrier 23 which is rotated in response to the deformation of the torsion limit spring 7 1 . Therefore, it is possible to form a collision detecting means with a simple configuration. Further, in the interlocking switch device of the present embodiment, the torsion limit springs 7 1 are balanced with respect to the traveling resistance when the sliding doors 11A and 11 are normally closed, so that the predetermined elastic force for suppressing the rotation of the carrier 23 acts on the carrier 23. The normal closing operation time is referred to as a time during which the force of the sliding door 1 1 A, 1 1 Β does not act from the outside, so that the elastic force balanced with the running resistance during the normal closing operation acts on the carrier 23 by the torsion limit spring 71. . Therefore, the elastic force acting by the torsion limit spring 71 can be made smaller. That is, the torsion limit spring 71 can be provided in a state where it can be easily deformed. Thereby, the increase in the running resistance with respect to the sliding doors 1 1 A and 1 1 使 causes the torsion limit spring 71 to be easily deformed, so that the sensing side with higher sensitivity can be performed.
