The top of the first door row assembly 21 is hoisted on the first suspension rail 11 and is slidably connected to the first suspension rail 11, and the top of the second door row assembly 22 is hoisted on the second suspension rail 12 and is slidably connected to the second suspension rail 12; the linkage assembly 30 links the first door row assembly 21 and the second door row assembly 22, and the first door row assembly 21 and the second door row assembly 22 can slide and unfold along a first direction, or slide and retract along a second direction, and the first direction and the second direction are opposite; the driving assembly 40 is connected to the first door row assembly 21, and the driving assembly 40 can drive the first door row assembly 21 to drive the second door row assembly 22 to slide.

[0042] As Figure 3 shown, Figure 3 shows that the door body 20 is fully unfolded along the first direction and slides to the closed position. The closed position refers to the position where the door body 20 is fully unfolded along the first direction and blocks the entrance and exit. At this time, the door body 20 blocks the entrance and exit to prevent pedestrians and vehicles from passing through. After the door body 20 is fully unfolded, it is in an elongated state as a whole. As Figure 4 shown, Figure 4 shows that the door body 20 is fully retracted along the second direction and slides to the open position. The open position refers to the position where the door body 20 is fully retracted along the second direction and is away from the entrance and exit. At this time, the door body 20 vacates the entrance and exit to allow pedestrians, vehicles, etc. to pass through. After the door body 20 is fully retracted, it is in a contracted state as a whole. In Figure 3and Figure 4 In the shown orientation, the first direction is to the left, the second direction is to the right, and the first direction and the second direction are parallel to the length direction of the suspension rail.

[0043] In the embodiment of the present utility model, on the one hand, by hoisting the top of each group of door row components (21, 22) onto a corresponding suspension rail (11, 12) and slidingly connecting with the corresponding suspension rail (11, 12), the suspension rail (11, 12) bears the corresponding door row components (21, 22), so that each group of door row components (21, 22) of the door body 20 does not need to rely on the support of the ground or track, etc. for sliding, avoiding the influence of foreign matters such as sand and gravel on the ground or track when the door row components (21, 22) slide, and it is difficult for foreign matters such as sand and gravel to enter the top suspension rail. The sliding friction of the door row components (21, 22) on the suspension rail (11, 12) is relatively smaller than the friction on the ground or track, and the operation is smoother, ensuring the stable operation of the door body 20; on the other hand, by arranging a linkage component 30 between the two groups of door row components (21, 22), each group of door row components (21, 22) can be linked when sliding, and a driving component 40 connected to the first door row component 21 is arranged. When opening / closing the door is required, only by controlling the driving component 40 to drive the first door row component 21 to slide along the second direction or the first direction, the door body 20 can be folded and slide to the open position or unfolded and slide to the closed position, which is convenient to use.

[0044] In the specific implementation process, the suspension rail assembly 10 can be installed on the ceiling, hanger or door top frame, etc., so that the door body 20 is integrally hoisted on the ceiling, hanger or door top frame, etc.

[0045] In some embodiments, the number of door row components of the door body 20 is two groups, namely the first door row component 21 and the second door row component 22 respectively. Correspondingly, the number of suspension rails of the suspension rail assembly 10 is two, and the number of linkage components 30 is one group. It can be understood that in some other embodiments, the number of door row components of the door body can be selected according to actual needs. The number of door row components is not limited to two groups. As long as one group of door row components corresponds to one suspension rail, and there is a group of linkage components correspondingly arranged between two adjacent groups of door row components. For example, the number of door row components is three groups, namely the first door row component, the second door row component and the third door row component respectively. Correspondingly, the number of suspension rails of the suspension rail assembly is three, and the number of linkage components is two groups. The first door row component, the second door row component and the third door row component are respectively hoisted on three suspension rails and slidingly connected with the corresponding suspension rails. One group of linkage components is linked to the first door row component and the second door row component, and the other group of linkage components is linked to the second door row component and the third door row component. The first door row component, the second door row component and the third door row component can slide and unfold along the first direction to block the passage, or slide and fold along the second direction to yield the passage.

[0046] In some embodiments, the first door row assembly 21 includes a first door row 211 and a first connecting member 212. The first connecting member 212 is connected to the first door row 211, and the first connecting member 212 is slidably connected to the first hanging rail 11. In this way, the hoisting of the first door row assembly 21 on the first hanging rail 11 is realized. The first hanging rail 11 bears the first door row 211 through the first connecting member 212, and the first door row 211 is slidably connected to the hanging rail through the first connecting member 212. The first door row 211 can slide along the first direction or the second direction on the first hanging rail 11 through the first connecting member 212, so that the first door row 211 can slide without relying on the support of the ground or the rail.

[0047] The second door row assembly 22 includes a second door row 221 and a second connecting member 222. The second connecting member 222 is connected to the second door row 221, and the second connecting member 222 is slidably connected to the second hanging rail 12.

The second door row 221 can slide along the first direction and the second direction on the second hanging rail 12 through the second connecting member 222, so that the second door row 221 can slide without relying on the support of the ground or the rail.

[0048] In some embodiments, the number of the first connecting members 212 and the number of the second connecting members 222 are both two. The two first connecting members 212 are respectively arranged at the tops of the left and right ends of the first door row 211 so that the first door row 211 can be hoisted on the first hanging rail 11 smoothly; the two second connecting members 222 are respectively arranged at the tops of the left and right ends of the second door row 221 so that the second door row 221 can be hoisted on the second hanging rail 12 smoothly.

[0049] It can be understood that the number of the first connecting members 212 and the number of the second connecting members 222 can be selected according to actual needs, as long as they are both at least two.

[0050] In some embodiments, the first door row 211 and the second door row 221 are parallel to each other, and, along the direction perpendicular to the first door row 211 and the second door row 221, the first door row 211 and the second door row 221 are arranged at intervals. By arranging the first door row 211 and the second door row 221 in this way, the first door row 211 and the second door row 221 are staggered from each other along the first direction and the second direction, so as to allow the first door row 211 and the second door row 221 to be unfolded or folded up.

[0051] In some embodiments, the first suspension rail 11 is provided with a first suspension groove 101, and the first suspension groove 101 is arranged along the length direction of the first suspension rail 11.

One end of the first connecting member 212 is received in the first suspension groove 101, and the two first bearing flanges 1011 bear the first connecting member 212 in the vertical direction. The other end of the first connecting member 212 extends out between the two first bearing flanges 1011, and the two first bearing flanges 1011 abut against the first connecting member 212 in the horizontal direction to prevent the first connecting member 212 from shifting back and forth relative to the two first bearing flanges 1011, so as to resist the front-back sway of the first door row assembly 21 relative to the first suspension rail 11. The second suspension rail 12 is provided with a second suspension groove 102, and the second suspension groove 102 is arranged along the length direction of the second suspension rail 12. Two second bearing flanges 1021 are provided at the notch of the second suspension groove 102, and the two second bearing flanges 1021 are arranged at intervals in the front-back direction at the notch of the second suspension groove 102. One end of the second connecting member 222 is received in the second suspension groove 102, and the two second bearing flanges 1021 bear the second connecting member 222 in the vertical direction. The other end of the second connecting member 222 extends out between the two second bearing flanges 1021, and the two second bearing flanges 1021 abut against the second connecting member 222 in the horizontal direction to prevent the second connecting member 222 from shifting back and forth relative to the two second bearing flanges 1021, so as to resist the front-back sway of the second door row assembly 22 relative to the suspension rail. Through the above settings, the stability of the door body 20 structure and the smoothness of the door body 20 during operation can be improved.

[0052] Specifically, the first connecting member 212 includes a first hanging wheel 2121 and a first hanging rod 2122. The first hanging wheel 2121 is received in the first hanging groove 101 and abuts against two first bearing flanges 1011. The first hanging wheel 2121 can slide in the first hanging groove 101 along the first direction or the second direction. The two first bearing flanges 1011 bear the first hanging wheel 2121 in the vertical direction. One end of the first hanging rod 2122 is connected to the first hanging wheel 2121, and the other end of the first hanging rod 2122 extends out between the two first bearing flanges 1011 and is connected to the first door row 211.

The first abutting member 31 is provided on the first door row assembly 21, and the second abutting member 32 is provided on the second door row assembly 22. During the process of the driving assembly 40 driving the first door row assembly 21 to slide, the first abutting member 31 and the second abutting member 32 can abut against each other to drive the second door row assembly 22 to slide together, so that the first door row assembly 21 and the second door row assembly 22 can slide together to the closed position or the open position.

[0054] Wherein, during the process of the driving assembly 40 driving the first door row assembly 21 to slide, the first abutting member 31 and the second abutting member 32 may not abut against each other, so that the first door row assembly 21 slides relative to the second door row assembly 22, thereby realizing the unfolding or folding of the door body 20.

[0055] A gap is provided between the first door row assembly 21 and the second door row assembly 22.

By disposing the abutting members on the left end face and / or the right end face of the door row, after the door body 20 is fully deployed, the overlapping portion of the first door row 211 and the second door row 221 in the front-rear direction can be reduced after the door body 20 is fully deployed, so that the door body 20 is as long as possible after being fully deployed. After the door body 20 is fully retracted, the overlapping portion of the first door row 211 and the second door row 221 in the front-rear direction can be increased after the door body 20 is fully retracted, so that the door body 20 is as short as possible after being fully retracted.

[0058] For the convenience of the reader's understanding, taking Figure 3 and Figure 4 the structure of the illustrated embodiment, the opening and closing process of the sliding door 100 will be described: As Figure 3 shown, when it is necessary for the door body 20 to make way for the entrance and exit, the first door row assembly 21 can be driven by the driving assembly 40 to slide in the second direction (rightward), so that the first door row assembly 21 slides relative to the second door row assembly 22 and approaches the right end of the second door row assembly 22. At the same time, the first door row assembly 21 drives the first abutting member 31 connected thereto to move. At this time, the first abutting member 31 and the second abutting member 32 do not abut against each other, and the second door row assembly 22 as a whole remains in the initial position when blocking the entrance and exit. As Figure 4 shown, until the first abutting member 31 moves to abut against the second abutting member 32 on the right end of the second door row assembly 22, the first door row assembly 21 and the second door row assembly 22 are in a fully retracted state. The first door row assembly 21 can drive the second door row assembly 22 to slide together in the second direction through the abutting action of the first abutting member 31 and the second abutting member 32 until the door body 20 completely makes way for the entrance and exit. As Figure 4 shown, when it is necessary for the door body 20 to block the entrance and exit, the first door row assembly 21 can be driven by the driving assembly 40 to slide in the first direction (leftward), so that the first door row assembly 21 slides relative to the second door row assembly 22 and moves away from the right end of the second door row assembly 22. At the same time, the first door row assembly 21 drives the first abutting member 31 connected thereto to move. At this time, the first abutting member 31 and the second abutting member 32 do not abut against each other, and the second door row assembly 22 as a whole remains in the initial position when making way for the entrance and exit. As Figure 3 shown, until the first abutting member 31 moves to abut against the second abutting member 32 on the left end of the second door row assembly 22, the first door row assembly 21 and the second door row assembly 22 are in a fully deployed state. The first door row assembly 21 can drive the second door row assembly 22 to slide together in the first direction through the abutting action of the first abutting member 31 and the second abutting member 32 until the door body 20 completely blocks the entrance and exit.

[0059] In some other embodiments, first abutting members 31 are provided at both the left end and the right end of the first door row assembly 21, and second abutting members 32 are provided at both the left end and the right end of the second door row assembly 22. Among them, when the first abutting member 31 on the left end of the first door row assembly 21 is located between the second abutting members 32 on the left end and the right end of the second door row assembly 22, and the first abutting member 31 on the right end of the first door row assembly 21 is located on the right side of the second abutting member 32 on the right end of the second door row assembly 22, the first direction is to the left and the second direction is to the right. The driving assembly 40 driving the first door row assembly 21 to slide to the left can achieve closing the door, and the driving assembly 40 driving the first door row assembly 21 to slide to the right can achieve opening the door; when the first abutting member 31 on the right end of the first door row assembly 21 is located between the second abutting members 32 on the left end and the right end of the second door row assembly 22, and the first abutting member 31 on the left end of the first door row assembly 21 is located on the left side of the second abutting member 32 on the left end of the second door row assembly 22, the first direction is to the right and the second direction is to the left. The driving assembly 40 driving the first door row assembly 21 to slide to the right can achieve closing the door, and the driving assembly 40 driving the first door row assembly 21 to slide to the left can achieve opening the door.

[0060] In some embodiments, both the first abutting member 31 and the second abutting member 32 are in the shape of a long plate.

[0061] In some other embodiments, the first abutting member 31 and the second abutting member 32 can also be in other shapes, for example, block-shaped, rectangular rod-shaped.

[0062] Please refer to Figure 8 and Figure 9 , Figure 8 is a side view of the sliding door 100 provided by another embodiment of the present utility model. Figure 9It is a top view of the sliding door 100 provided by another embodiment of the present utility model. The linkage assembly 30A includes a first abutting member 31A and a first stopper corresponding to the first abutting member 31A, and / or a second abutting member 32A and a second stopper corresponding to the second abutting member 32A. Wherein, one end of the first abutting member 31A is connected to the second door row assembly 22. The first door row assembly 21 is provided with a first sliding groove 201. The other end of the first abutting member 31A extends into the first sliding groove 201. The first sliding groove 201 and the first hanging rail 11 are parallel to each other. The first stopper is arranged at both ends of the first sliding groove 201. In this way, when the first abutting member 31A moves along the first direction or the second direction, it can respectively abut against the first stoppers at both ends of the first sliding groove 201, so that the first door row assembly 21 and the second door row assembly 22 slide together along the first direction or the second direction. Wherein, when the first abutting member 31A and the first stopper do not abut against each other, the first door row assembly 21 and the second door row assembly 22 can be unfolded or folded; one end of the second abutting member 32A is connected to the first door row assembly 21. The second door row assembly 22 is provided with a second sliding groove. The second sliding groove and the second hanging rail 12 are parallel to each other. The other end of the second abutting member 32A extends into the second sliding groove. The second stopper is arranged at both ends of the second sliding groove. In this way, when the second abutting member 32A moves along the first direction or the second direction, it can respectively abut against the second stoppers at both ends of the second sliding groove 201, so that the first door row assembly 21 and the second door row assembly 22 slide together along the first direction or the second direction. Wherein, when the second abutting member 32A and the second stopper do not abut against each other, the first door row assembly 21 and the second door row assembly 22 can be unfolded or folded.

[0063] In this embodiment, by inserting the other end of the first abutting member 31A on the second door row assembly 22 into the first sliding groove 201 of the first door row assembly 21 and inserting the other end of the second abutting member 32A on the first door row assembly 21 into the second sliding groove of the second door row assembly 22, the other ends of the first abutting member 31A and the second abutting member 32A can be respectively accommodated. There is no need to reserve a too large gap between the first door row assembly 21 and the second door row assembly 22, reducing the spacing distance between the first door row assembly 21 and the second door row assembly 22, preventing the human hand from being accidentally pinched in the gap between the first door row assembly 21 and the second door row assembly 22, and reducing the overall thickness of the door body 20. Moreover, the other end of the first abutting member 31A abuts against the first stop block inside the first door row assembly 21, and the other end of the second abutting member 32A abuts against the second stop block inside the second door row assembly 22. In this way, the lever arm between the two ends of the first abutting member 31A and the lever arm between the two ends of the second abutting member 32A can be shortened, and the acting force exerted by the other end of the first abutting member 31A on the first door row assembly 21 is closer to the central plane of the first door row assembly 21, and the acting force exerted by the other end of the second abutting member 32A on the second door row assembly 22 is closer to the central plane of the second door row assembly 22, enabling the first door row assembly 21 and the second door row assembly 22 to run more smoothly after the first abutting member 31A abuts against the first stop block and the second abutting member 32A abuts against the second stop block.

[0064] Wherein, the central plane of the first door row assembly 21 refers to the central plane in the front-rear direction of the first door row assembly 21, and the central plane of the second door row assembly 22 refers to the central plane in the front-rear direction of the second door row assembly 22.

[0065] In some embodiments, the first stop block and the second stop block are made of a material with a certain elasticity to play a buffering role when the first abutting member 31A abuts against the first stop block and the second abutting member 32A abuts against the second stop block, preventing rigid collision and causing structural damage.

[0066] In some embodiments, the first sliding groove 201 and the second sliding groove are at the same height. One end of the first abutting member 31A is fixed in the second sliding groove, and one end of the second abutting member 32A is fixed in the first sliding groove 201. In this way, the force application points where the first abutting member 31A abuts against the first stop block and the second abutting member 32A abuts against the second stop block can also be at the same height, so that the forces at both ends of the first door row assembly 21 and both ends of the second door row assembly 22 are balanced, which is beneficial to the first door row assembly 21 and the second door row assembly 22 running more smoothly.

[0067] Wherein, the first sliding groove 201 and the second sliding groove being at the same height means that after the door body 20 is installed, the horizontal heights of the first sliding groove 201 and the second sliding groove are equal.

[0068] Specifically, the first sliding groove 201 is provided on the first door row 211, and the second sliding groove is provided on the second door row 221; one end of the first abutting member 31A is connected to the second door row 221, and one end of the second abutting member 32A is connected to the first door row assembly 211.

[0069] In some embodiments, one end of the first abutting member 31A is fixed to the left end side of the second sliding groove, and one end of the second abutting member 32A is fixed to the right end side of the first sliding groove 201. Through the above settings, the position of the first abutting member 31A relative to the second door row 221 is fixed, and the position of the second abutting member 32A relative to the first door row 211 is fixed, improving the stability when the door body 20 operates; moreover, after the door body 20 is fully unfolded, the overlapping part of the first door row 211 and the second door row 221 in the front-rear direction can be reduced, so that the door body 20 is as long as possible after being fully unfolded, and after the door body 20 is fully retracted, the overlapping part of the first door row 211 and the second door row 221 in the front-rear direction can be increased, so that the door body 20 is as short as possible after being fully retracted.

[0070] The first abutting member 31A includes a first abutting wheel 311A and a first abutting rod 312A. The first abutting wheel 311A is received in the first sliding groove 201 and is slidably connected to the first sliding groove 201. One end of the first abutting rod 312A is connected to the second door row assembly 22, and the other end of the first abutting rod 312A is connected to the first abutting wheel 311A; the second abutting member 32A includes a second abutting wheel 321A and a second abutting rod 322A. The second abutting wheel 321A is received in the second sliding groove and is slidably connected to the second sliding groove. One end of the second abutting rod 322A is connected to the first door row assembly 21, and the other end of the second abutting rod 322A is connected to the second abutting wheel 321A.

[0071] In this embodiment, by setting the other ends of the first abutting member 31A and the second abutting member 32A as roller structures and making them slidably connected to the first chute 201 and the second chute respectively, the friction between the other end of the first abutting member 31A in the first chute 201 and the friction between the other end of the second abutting member 32A in the second chute can be reduced, making the movement of the other end of the first abutting member 31A in the first chute 201 and the other end of the second abutting member 32A in the second chute smoother. Moreover, the first chute 201 and the second chute can guide the first abutting wheel 311A and the second abutting wheel 321A respectively, so that when the first abutting wheel 311A slides relative to the first door row assembly 21, it always moves along the length direction parallel to the first hanging rail 11, and when the second abutting wheel 321A slides relative to the second door row assembly 22, it always moves along the length direction parallel to the second hanging rail 12, that is, the sliding directions of the first abutting wheel 311A and the second abutting wheel 321A are parallel to each other, which is beneficial to improving the sliding stability of the first door row assembly 21 and the second door row assembly 22 relative to each other.

[0072] At the notch of the first chute 201, there are two first limiting flanges 2011 for restricting the first abutting wheel 311A from detaching from the notch of the first chute 201. The two first limiting flanges 2011 are arranged at intervals up and down at the notch of the first chute 201. The other end of the first abutting rod 312A passes through between the two first limiting flanges 2011 and is connected to the first abutting wheel 311A. At the notch of the second chute, there are two second limiting flanges for restricting the second abutting wheel 321A from detaching from the notch of the second chute. The two second limiting flanges are arranged at intervals up and down at the notch of the second chute, and the other end of the second abutting rod 322A passes through between the two second limiting flanges and is connected to the second abutting wheel 321A.

[0073] In this embodiment, by providing two first limiting flanges 2011 at the notch of the first chute 201 and two second limiting flanges at the notch of the second chute, in this way, the two first limiting flanges 2011 can abut against the first abutting wheel 311A in the horizontal direction, and the two second limiting flanges can abut against the second abutting wheel 321A in the horizontal direction, thereby restricting the first abutting wheel 311A from detaching from the notch of the first chute 201 along the direction from the first door row 211 to the second door row 221, and restricting the second abutting wheel 321A from detaching from the notch of the second chute along the direction from the second door row 221 to the first door row 211. Moreover, the two first limiting flanges 2011 can also abut against the first abutting rod 312A in the vertical direction, and the two second limiting flanges can also abut against the second abutting rod 322A in the vertical direction to support the first abutting rod 312A and the second abutting rod 322A, improving the connection stability between the first door row assembly 21 and the second door row assembly 22.

[0074] In some embodiments, the driving assembly 40 includes a driving motor 41 and a transmission mechanism 42. The driving motor 41 is connected to the transmission mechanism 42, and the transmission mechanism 42 is connected to the first door row assembly 21. Starting the driving motor 41 can drive the transmission mechanism 42 to move. The transmission mechanism 42 drives the first door row assembly 21 to drive the second door row assembly 22 to unfold along the first direction or to fold up along the second direction.

[0075] The transmission mechanism 42 includes two belt pulleys 421, a belt 422 and a driving member 423. The two belt pulleys 421 are arranged at intervals along a direction parallel to the first suspension rail 11. The belt 422 is wound around the two belt pulleys 421. One end of the driving member 423 is connected to the belt 422, and the other end of the driving member 423 is connected to the first door row assembly 21. The output shaft of the driving motor 41 is connected to one of the two belt pulleys 421.

[0076] When the driving motor 41 is started and the left belt pulley 421 rotates clockwise, the left belt pulley 421 drives the belt 422 to run clockwise around the two belt pulleys 421. At the same time, the belt 422 drives the first door row assembly 21 through the driving member 423 to drive the second door row assembly 22 to slide and unfold along the first direction. When the driving motor 41 is started and the left belt pulley 421 rotates counterclockwise, the left belt pulley 421 drives the belt 422 to run counterclockwise around the two belt pulleys 421. At the same time, the belt 422 drives the first door row assembly 21 through the driving member 423 to drive the second door row assembly 22 to slide and fold up along the second direction.

[0077] In some other embodiments, the belt pulley 421 can be replaced by a sprocket, and the belt 422 can be replaced by a chain, and the chain is wound around the two sprockets; or, the belt pulley 421 can be replaced by a drum, and the belt 422 can be replaced by a steel wire rope. The driving motor 41 drives the drum to rotate to wind and unwind the steel wire rope, so as to drive the first door row assembly 21 to slide.

[0078] In some other embodiments, the transmission mechanism can also be other components capable of transmitting motion between the driving motor 41 and the door body 20. For example, the transmission assembly includes a gear and a rack. The gear is connected to the output end of the driving motor 41. The rack is parallel to the first suspension rail 11. The rack is arranged on the first door row assembly 21. The gear meshes with the rack. Starting the driving motor 41 can make the gear rotate, and the gear drives the rack and the first door row assembly 21 to drive the second door row assembly 22 to move.

[0079] Please refer to Figure 8, the sliding door 100 further includes a guide rail assembly 50. The guide rail assembly 50 includes a first guide rail 51 and a second guide rail 52. The bottom of the first door row assembly 21 is slidably connected to the first guide rail 51, and the bottom of the second door row assembly 22 is slidably connected to the second guide rail 52. In this way, the bottoms of the first door row assembly 21 and the second door row assembly 22 can be respectively guided when the door body 20 slides, so that the door body 20 remains stable up and down when sliding. Moreover, the first guide rail 51 and the second guide rail 52 can respectively play a role in front-back limiting for the bottoms of the first door row assembly 21 and the second door row assembly 22, preventing the bottom of the first door row assembly 21 from swaying back and forth relative to the top of the first door row assembly 21, and preventing the bottom and the top of the second door row assembly 22 from swaying back and forth, improving the wind resistance of the door body 20 and ensuring the stability of the door body 20 during operation. And, the first hanging rail 11 and the first guide rail 51 are located in the same vertical plane, and the second hanging rail 12 and the second guide rail 52 are located in the same vertical plane. In this way, the moment between the first door row assembly 21 between the first hanging rail 11 and the first guide rail 51 can be reduced, and the moment between the second door row assembly 22 between the second hanging rail 12 and the second guide rail 52 can be reduced, improving the structural stability of the door body 20.

[0080] In some embodiments, the first guide rail 51 includes two first limiting plates 511 which are parallel to each other and spaced apart. The second guide rail 52 includes two second limiting plates 521 which are parallel to each other and spaced apart. The first door row assembly 21 further includes a first guiding member 213. The first guiding member 213 includes a first guiding wheel 2131 and a first guiding rod 2132. The first guiding wheel 2131 is located between the two first limiting plates 511, and the circumferential outer wall of the first guiding wheel 2131 abuts against the two first limiting plates 511. One end of the first guiding rod 2132 is connected to the bottom of the first door row 211, and the other end of the first guiding rod 2132 is connected to the first guiding wheel 2131. The second door row assembly 22 further includes a second guiding member 223. The second guiding member 223 includes a second guiding wheel 2231 and a second guiding rod 2232. The second guiding wheel 2231 is located between the two first limiting plates 511, and the circumferential outer wall of the second guiding wheel 2231 abuts against the two second limiting plates 521. One end of the second guiding rod 2232 is connected to the bottom of the second door row 221, and the other end of the second guiding rod 2232 is connected to the second guiding wheel 2231. Through the above arrangement, the two first limiting plates 511 can respectively abut against the first guiding wheel 2131, and the two second limiting plates 521 can respectively abut against the second guiding wheel 2231 to limit the front-back movement of the first guiding member 213 relative to the first guide rail 51 and the front-back movement of the second guiding member 223 relative to the second guide rail 52, preventing the bottom of the door body 20 from swaying back and forth relative to the top. Moreover, the first guiding wheel 2131 and the second guiding wheel 2231 can slide in the first guide rail 51 and the second guide rail 52 respectively, thereby reducing the frictional force generated between the first guiding wheel 2131 and the first guide rail 51, and between the second guiding wheel 2231 and the second guide rail 52.

[0081] Please refer back Figure 3 and Figure 4 Moreover, the sliding door 100 further includes a stopper 60 for restricting the door body 20 from continuing to slide along the first direction when the door body 20 slides to the closed position, and restricting the door body 20 from continuing to slide along the second direction when the door body 20 slides to the open position. The stopper 60 is located on the left and right sides of the door body 20 to prevent the door body 20 from continuing to slide under the action of inertia after sliding in place and deviating from the closed position or the open position.

[0082] Specifically, the first door row assembly 21 is the driving part, and the second door row assembly 22 is the driven part. During the sliding of the door body 20, the second door row assembly 22 is driven to slide by the first door row assembly 21. There are two stoppers 60, and the two stoppers 60 are respectively located on the left and right sides of the second door row assembly 22. When the first door row assembly 21 drives the second door row assembly 22 to slide along the first direction to the closed position, the left stopper 60 abuts against the left end of the second door row assembly 22, thereby preventing the first door row assembly 21 from continuing to drive the second door row assembly 22 to slide along the first direction, so that the first door row assembly 21 and the second door row assembly 22 are held at the closed position in a fully deployed state; when the first door row assembly 21 drives the second door row assembly 22 to slide along the second direction to the open position, the right stopper 60 abuts against the right end of the second door row assembly 22, thereby preventing the first door row assembly 21 from continuing to drive the second door row assembly 22 to slide along the second direction, so that the first door row assembly 21 and the second door row assembly 22 are held at the open position in a fully retracted state.

[0083] In the specific implementation process, the stopper 60 can be arranged on the ceiling, hanger or door top frame.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other changes in different aspects of the present invention as described above.
