The currently used sliding plug door lock structure is that when the vehicle door is closed, a guide wheel on the door lock is guided into a guide rail on the vehicle frame, the movement of the door lock is limited through the guide rail, and the door lock is fixed on the vehicle door, so that the movement of the vehicle door is limited, and the purpose of locking the door is achieved. However, the door lock structure has great potential safety hazard, because the vehicle is in a driving process and the road surface is hollow, the guide wheel on the door lock can roll back and forth in the guide rail, so that the door is poor in sealing performance, and airflow can enter the vehicle from the door gap during high-speed running to influence the riding experience of passengers; when the vibration is large, the phenomenon that the guide wheel returns from the original path in the guide rail and slides out can even occur, so that the vehicle door can be automatically opened, and great potential safety hazard exists.
Although some sliding plug door locks can avoid the problem that the door is automatically opened when the door shakes and jolts, generally, the opening and closing of the door and the locking and unlocking of the door lock respectively need a driving mechanism, namely, the whole set of door needs at least two sets of driving motors, one set of driving motors is used for driving the locking and unlocking of the door lock, the other set of driving motors is used for driving the opening and closing of the door lock, the cost is undoubtedly increased, and the structure of the door is complex.

After the design, when the first elastic piece is positioned at one side of a connecting point of the middle part of the clamping block and the tray in rotating connection, the clamping block and the stopper to be locked are locked; when the first elastic piece is positioned on the other side of the connecting point where the middle part of the clamping block is rotatably connected with the tray, the clamping block is separated from the stopper to be locked and unlocked.
Preferably, the first elastic member is a tension spring.
Furthermore, the bottom of the clamping block is rotatably connected with a transition block, a rotating shaft of the transition block is parallel to the stirring pin, and the transition block is positioned on the upper portion or the lower portion of the stirring pin. When the clamping block is clamped with a stopper to be locked, the transition block is positioned above the toggle pin, and the first elastic piece is positioned on one side of a connecting point of the middle part of the clamping block and the tray in rotating connection; when the clamping block and the stopper to be locked are in the process from the clamping state to the separation state, the poking pin can be in contact with the transition block for a period of time, and the transition block is rotationally connected with the clamping block, so the poking pin can be positioned above the transition block after crossing the transition block, and at the moment, the first elastic piece is positioned on the other side of the connecting point where the middle part of the clamping block is rotationally connected with the tray, so that the clamping block and the stopper to be locked are forced to be separated and unlocked.
Furthermore, the locking linkage assembly comprises a poke rod, a poke pin, a sleeve rod and a linkage block, the bottom end of the poke rod is connected with the driving block, and the top end of the poke rod is rotatably connected to the tray; the poke rod is provided with a first limiting hole for limiting one end of the sleeve rod, one end of the sleeve rod is positioned in the first limiting hole, and the other end of the sleeve rod is fixedly connected with the linkage block; one end of the linkage block is rotatably connected to the tray, and the other end of the linkage block is connected with the poking pin. When a door needs to be locked, the driving motor rotates forwards to drive the screw rod to rotate forwards, the screw rod drives the screw rod nut in threaded connection to do linear motion along the screw rod by the forward rotation of the screw rod, so as to drive the door carrying frame fixed with the screw rod nut and the door plate fixed with the door carrying frame to move to one side, when the door carrying frame or a certain part synchronously moving with the door carrying frame moves to extrude the driving block in the locking driving assembly, the driving block is extruded to rotate along the tray to drive the poking rod to rotate, so as to drive the sleeve rod to rotate together with the linkage block, the rotation of the linkage block drives the poking pin to rotate, the poking pin can be contacted with the transition block below the clamping block when rotating to a certain position, the transition block drives the clamping block to rotate around the forward direction of the tray, the rotation of the clamping block enables the first elastic piece to gradually rotate from the side far away from the stopper to be locked, when the straight line where the first elastic piece is located crosses the connecting point between the clamping block and, the clamping block can be clamped on the stopper to be locked, and the transition block is positioned below the left side of the shifting pin and separated from the shifting pin; when the door needs to be opened, the driving motor reversely rotates to drive the unlocking mechanism to unlock the clamping block, the unlocking mechanism separates the clamping block from the stopper to be locked, the unlocking mechanism can force the clamping block to rotate reversely around the tray in the separation process, the rotation of the clamping block enables the straight line of the first elastic piece to cross the rotating connection point between the clamping block and the tray again, and then the first elastic piece can also force the clamping block to rotate reversely, so that the clamping block and the stopper to be locked are separated and unlocked; then, the driving motor continues to rotate reversely to drive the lead screw to rotate, the lead screw nut on the lead screw is driven to move reversely by the rotation of the lead screw, the door carrying frame fixedly connected with the lead screw nut is driven to move reversely with the door plate fixed below the door carrying frame, and the vehicle door is opened. After the door carrying frame or a certain part synchronously moving with the door carrying frame reversely moves to be separated from the driving block, the driving block reversely rotates along the tray under the driving of the second elastic part, the shifting rod is driven to reversely rotate, the shifting rod drives the sleeve rod to reversely rotate, and then the linkage block and the shifting pin are driven to reversely rotate, so that the locking driving assembly and the locking linkage assembly are restored to the initial state, and the transition block is still positioned below the shifting pin and separated from the shifting pin.
Furthermore, the locking driving assembly comprises a driving block and a second elastic piece, the driving block is rotatably connected with the tray through a rotating shaft, one end of the second elastic piece is fixed with the rotating shaft, and the other end of the second elastic piece is fixed with the driving block; when the driving block is extruded by external force, the driving block can rotate around the rotating shaft along the tray. When a door needs to be locked, the driving motor rotates forwards to drive the screw rod to rotate forwards, the screw rod rotates forwards to drive the screw rod nut on the screw rod to do linear motion along the screw rod, so that the door carrying frame fixed with the screw rod nut and the door plate fixed with the door carrying frame are driven to move towards one side, when the door carrying frame or a certain part moving synchronously with the door carrying frame extrudes the driving block in the locking driving assembly, the driving block rotates around the rotating shaft along the forward direction of the tray after being extruded, and the second elastic part is tensioned; when the door needs to be opened, the driving motor drives the lead screw to rotate reversely, the lead screw drives the lead screw nut on the lead screw to move reversely by rotation of the lead screw, and then the door carrying frame fixedly connected with the lead screw nut and the door panel fixed below the door carrying frame are driven to move reversely, and the door is opened. After the door carrying frame or a part synchronously moving with the door carrying frame reversely moves to be separated from the driving block, the driving block reversely rotates along the tray to an initial state under the driving of the second elastic piece.
Furthermore, the locking driving assembly further comprises a guide part, the guide part is rotatably connected with the driving block, and when the driving block is extruded by external force and rotates around the rotating shaft along the tray, the guide part is in direct contact with an object applying the external force.

Preferably, the guide member is a roller rotatably connected to the driving block. The active block is indirectly contacted with the object applying the external force through the roller, sliding friction between the active block and the object applying the external force is changed into rolling friction, and friction force between the active block and the object applying the external force is effectively reduced.
Furthermore, a second limiting hole for limiting the poke rod is formed in the driving block, and the bottom end of the poke rod is located in the second limiting hole.

Further, the spiral-linear shaft sleeve is of a solid shaft structure, the outer wall of one end of the spiral-linear shaft sleeve is provided with a spiral key A34, and the outer wall of the other end of the spiral-linear shaft sleeve is provided with a plurality of splines A35 which are distributed circumferentially and are parallel to the central axis of the spiral-linear shaft sleeve; the inner wall of the output shaft of the driving motor is provided with spiral teeth A32 or ribs A33 matched with the spiral key A34 or the spline A35, and the inner wall of the guide shaft is provided with ribs B38 or spiral teeth B39 matched with the spline A35 or the spiral key A34; the end of the spiral-straight shaft sleeve with the spiral key A34 is nested in the spiral tooth A32 or the spiral tooth B39, and the end with the spline A35 is nested in the rib A33 or the rib B38. When the spiral-linear shaft sleeve is used as a shaft, two ends of the spiral-linear shaft sleeve are required to ensure that one end of the spiral-linear shaft sleeve is a spiral key and the other end of the spiral-linear shaft sleeve is a spline parallel to the central axis of the spiral-linear shaft sleeve, so that when the driving motor drives the spiral-linear shaft sleeve to move through spiral teeth or ribs on an output shaft of the driving motor, the spiral-linear shaft sleeve can only be driven to do short-distance spiral linear motion before a guide shaft does not rotate along with a stopper to be locked, and the spiral-linear shaft sleeve drives a poking rod to move back and forth, thereby realizing the purpose.
Furthermore, one end of the spiral-linear shaft sleeve is of a hollow cylindrical structure, the other end of the spiral-linear shaft sleeve is of a solid shaft structure, the inner wall of one end with the hollow cylindrical structure is provided with spiral teeth A32 or a plurality of ribs A33 which are distributed circumferentially and are parallel to the central axis of the hollow cylindrical structure, and one end with the solid shaft structure is provided with a spline A35 or a spiral key A34; the outer wall of the output shaft of the driving motor is provided with a spiral key B37 or a spline B36 matched with the spiral tooth A32 or the rib A33, and the inner wall of the guide shaft is provided with a rib B38 or a spiral tooth B39 matched with the spline A35 or the spiral key A34; one end of the spiral-linear shaft sleeve with a hollow structure is sleeved on the output shaft for driving the motor, and the other end with a solid shaft structure is nested in the guide shaft; or the inner wall of the output shaft of the driving motor is provided with ribs C40 or spiral teeth C42 matched with the spline A35 or the spiral key A34; the outer wall of the guide shaft is provided with a spiral key C41 or a spline C43 which is matched with the spiral teeth A32 or the ribs A33; one end of the spiral-linear shaft sleeve with a hollow structure is nested in the output shaft for driving the motor, and one end with a solid shaft structure is nested on the guide shaft. When one end of the spiral-linear shaft sleeve is used as a shaft and the other end of the spiral-linear shaft sleeve is used as a sleeve, the two ends of the spiral-linear shaft sleeve are required to ensure that one end of the spiral-linear shaft sleeve is provided with a spiral tooth or spiral key structure and the other end of the spiral-linear shaft sleeve is provided with a linear spline or rib structure, so that when the driving motor drives the spiral-linear shaft sleeve to move through the spiral tooth or rib on the output shaft of the driving motor, the spiral-linear shaft sleeve can only be driven to do short-distance spiral linear motion before the guide shaft does not rotate along with the stopper to be locked, and the spiral-linear shaft sleeve drives the poking rod.
Further, a first buffer member is sleeved between the spiral-linear shaft sleeve and the output shaft of the driving motor, and/or a second buffer member is sleeved between the spiral-linear shaft sleeve and the guide shaft. The first buffer piece and/or the second buffer piece are arranged to limit and fix the position of the spiral-linear shaft sleeve, so that the spiral-linear shaft sleeve is prevented from moving left and right between the output shaft and the guide shaft of the driving motor to influence the unlocking effect.

In the invention, the to-be-locked stopper can only rotate clockwise and can not rotate reversely after being clamped by the clamping block, so when the clamping block is clamped on the to-be-locked stopper, the to-be-locked stopper can not rotate reversely due to vibration and the like, and when the to-be-locked stopper rotates clockwise due to vibration, bumping and the like, the door lock clutch device can tightly lock the door lock, so that the clamping block and the to-be-locked stopper are always in a clamping state; in practical application, the door lock clutch device is generally fixed on a bus door, a subway door or a high-speed railway door and the like, and is relatively static with the door, so that the door lock clutch device can effectively prevent the locked door from being automatically opened due to vibration in the driving process; it is also for the above reasons that the door equipped with the present door lock clutch device can be closed better.
The process also shows that the locking and unlocking of the door lock clutch device and the opening or closing of the door panel share one driving motor, so that the locked door can be effectively prevented from being automatically opened in bumpy operation, and the locked door has good tightness; simple structure, mechanism reasonable in design can effectively reduce stopper sliding door's cost.

The locking and unlocking principle of the door lock clutch device is as follows:
the initial state of the door lock clutch device is an unlocked state, at this time, the upper pawl of the clamping block 27 and the stopper 12 (ratchet wheel) to be locked are in a separated state, and the driving lever 44 and the clamping block 27 are not contacted, as shown in fig. 2; when the door lock clutch device needs to be locked in a closed mode, the driving motor 3 drives the spiral-linear shaft sleeve 30 to rotate in the original place in the positive direction, further drives the guide shaft 31 and the stopper 12 to be locked to rotate in the original place in the positive direction, further drives the lead screw coaxially fixed with the stopper 12 to be locked to rotate in the original place in the positive direction, further drives the lead screw nut in threaded connection with the lead screw to move rightwards along the lead screw, and drives the door carrying frame fixedly connected with the lead screw nut and the door panel fixed on the lower portion of the door carrying frame to.
When the door panel moves to the right and closes, the door carrying frame or a certain part moving synchronously with the door carrying frame will contact and gradually press the guide part 17 at the bottom of the active block 16, the guide part 17 rolls along the certain part contacting with the guide part, thereby driving the active block 16 to rotate around the rotating shaft 19 on the tray 11 in the positive direction under the action of the second elastic part 18, driving the poking rod 21 to rotate around the rotating shaft in the positive direction on the tray 11, the poking rod 21 pokes the sleeve rod 23 to rotate in the positive direction, the sleeve rod 23 drives the linkage block 24 to rotate in the positive direction, the linkage block 24 drives the poking pin 22 to rotate in the positive direction and move downwards, when the poking pin 22 rotates and moves downwards to contact with the transition block 28 at the bottom of the clamping block 27, the transition block 28 is pressed to force the clamping block 27 to rotate around the rotating shaft in the positive direction on the tray 11, the rotation of the clamping block 27 makes the first elastic part 29 rotate from the side far away from and gradually approaching, the first elastic member 29 is located on the side of the rotation connection point of the clamping block 27 and the tray 11 far from the stopper 12 to be locked), when the clamping block 27 drives the first elastic member 29 to rotate to cross the rotation connection point of the clamping block 27 and the tray 11, the pawl of the clamping block 27 can be locked in the ratchet teeth of the stopper 12 to be locked, as shown in fig. 1, the door panel is locked in a closed state, and the driving motor 3 stops driving.
After the clamping block 27 is clamped with the stopper 12 to be locked, the stopper 12 to be locked can only rotate in the positive direction and can not rotate in the negative direction, and after the clamping block 27 is clamped and locked with the stopper 12 to be locked, if no external force is used for separating the clamping block 27 from the stopper 12 to be locked, the stopper 12 to be locked is always in a locking state; when the stopper 12 to be locked is rotated in a forward direction due to a jolt shock or the like, the locking piece 27 locks it more tightly. In addition, at the instant when the first elastic member 29 passes over the rotational connection point of the chucking block 27 and the tray 11, the transition block 28 is separated from and located below the toggle pin 22. When the clamping block 27 and the stopper 12 to be locked are clamped, that is, the screw cannot rotate, the screw nut connected with the screw thread cannot move, the door carrying frame fixedly connected with the screw nut and the door panel fixed at the lower part of the door carrying frame cannot move, and then the door panel is closed and locked.
When the door panel needs to be opened, the driving motor 3 rotates reversely through the output shaft 61 to drive the spiral-linear shaft sleeve 30 to rotate reversely around the axis, because the spiral-linear shaft sleeve 30 has a structure, one end of the spiral-linear shaft sleeve 30 is provided with a spiral tooth or a spiral key, and the other end is provided with a rib or a spline, when the driving motor 3 drives the spiral-linear shaft sleeve 30 to rotate reversely through the spiral key, the spline, the spiral tooth or the rib on the output shaft 61, the spiral-linear shaft sleeve 30 can only be forced to linearly advance spirally (leftwards in the figure) along the rib or the spline on the output shaft 61 or the guide shaft 31 of the driving motor 3 before the guide shaft 31 rotates along with the stopper 12 to be locked, the advancing of the spiral-linear shaft sleeve 30 drives the tail end of the driving lever 44 which is connected with the spiral-linear shaft sleeve to rotate, and the middle part of the driving lever 44 is connected with the tray 11 in a, the front end of the shift lever 44 is forced to rotate from the far side to the near side of the locking block 27, when the front end of the shift lever 44 rotates to contact with the upper part of the upper pawl of the locking block 27, the further advance of the spiral-linear shaft sleeve 30 forces the shift lever 44 to shift the locking block 27 to rotate in the opposite direction, during the rotation of the locking block 27, the first elastic member 29 rotates from the near side to the far side from the stopper 12 to be locked (when the locking block 27 is locked with the stopper 12 to be locked, the first elastic member 29 is located at the side where the rotation connection point of the locking block 27 and the tray 11 is close to the stopper 12 to be locked), and when the first elastic member 29 rotates with the locking block 27 to cross the rotation connection point of the locking block 27 and the tray 11, the first elastic member 29 can completely pull the locking block 27 to prevent it from being locked with the stopper 12 to be locked again.
The third elastic member 45 is rotated from the side close to the stopper 12 to be locked to the side away from the stopper 12 to be locked, and the third elastic member 45 is also rotated from the side close to the stopper 12 to be locked to the side away from the stopper 11 to be locked, and when the first elastic member 29 passes over the pivotal connection point between the lock lever 27 and the tray 11, the third elastic member 45 also passes over the pivotal connection point between the lock lever 44 and the tray 11, so that the third elastic member 45 can pull the lock lever 44 tightly and effectively separate the lock lever 27 from the stopper 12 to be locked.
In the unlocking process, the driving motor 3 drives the spiral-linear shaft sleeve 30 to move leftwards in a linear mode all the time, when unlocking is successful (namely, when the driving block 16 is restored to the initial state), the stopper 12 to be locked can rotate in situ and reversely synchronously under the driving of the driving motor 3 along with the spiral-linear shaft sleeve 30 and the guide shaft 31, further, the lead screw coaxially fixed with the stopper 12 to be locked can rotate in situ and reversely, further, the lead screw nut 5 in threaded connection with the lead screw can move leftwards along the lead screw, the door carrying frame fixedly connected with the lead screw nut is driven to move leftwards, further, the door plate fixed at the lower portion of the door carrying frame is driven to move leftwards, and when the door plate moves leftwards to the leftmost side, the door opening is.
In the unlocking process, after the door carrying frame or a part moving synchronously with the door carrying frame moves to the left to be separated from the driving block 16, the driving block 16 rotates reversely to the initial position under the action of the second elastic piece 18, so that the poking rod 21, the sleeve rod 23, the linkage block 24 and the poking pin 22 are driven to rotate reversely, and the locking linkage assembly and the locking driving assembly are restored to the initial state.
When the door plate to be opened needs to be closed again, the driving motor 3 drives the lead screw coaxially fixed with the stopper 12 to be locked to rotate in the positive direction again, the positive direction rotation of the lead screw drives the lead screw nut in threaded connection with the lead screw, the door carrying frame fixedly connected with the lead screw nut and the door plate fixed at the lower part of the door carrying frame to move in the positive direction, meanwhile, the forward driving of the driving motor 3 will drive the spiral-linear shaft sleeve 30 to move linearly and rightwards, the right movement of the spiral-linear shaft sleeve 30 will drive the shift lever 44 connected with it to rotate around the connection point connected with the tray 11, the front end of the shift lever 44 is rotated away from the fastening block 27, and after the third elastic member 45 is rotated to pass over the rotational connection point of the shift lever 44 and the tray 11, the shift lever 44 is completely separated from the clamping block 27, and rotates in situ after the spiral-linear shaft sleeve moves rightwards to the initial position; when the first sleeve 6 moves to the right and is extruded to the driving block 16 in the locking driving component, the locking driving component locks the clamping block 27 in the clamping component on the stopper 12 to be locked through the locking linkage component, so as to realize the closing and locking of the door panel; then the driving motor stops driving, the spiral-linear shaft sleeve also stops rotating, and the next unlocking action is waited.
In practical applications, it is preferable that the first buffer 46 is sleeved between the spiral-linear shaft sleeve 30 and the output shaft 61 of the driving motor 3, and the second buffer 47 is sleeved between the guide shaft 31; the first and second dampers 46 and 47 preferably use springs. The first buffer 46 and the second buffer 47 are disposed to limit and fix the position of the spiral-linear shaft sleeve 30 between the driving motor 3 and the guide shaft 31, so as to prevent the spiral-linear shaft sleeve 30 from moving left and right between the output shaft 61 of the driving motor 3 and the guide shaft 31, thereby affecting the unlocking effect, and in addition, the spiral-linear shaft sleeve 30 can also be buffered, so as to prevent the two ends of the spiral-linear shaft sleeve 30 from colliding with the output shaft 61 of the driving motor 3 and the guide shaft 31 to be damaged.
