[0038] See also Figure 1 , Figure 1 This is a front view of a sliding door 100 provided in one embodiment of the present invention. The present invention provides a sliding door 100 installed at an entrance and exit for managing the entrance and exit.

[0039] Please also refer to Figures 2 to 5 , Figure 2 yes Figure 1 The side view of the sliding door 100 shown in FIG. Figure 3 yes Figure 1 Another side view of the sliding door 100 is shown, wherein Figure 3 Omit the first door row assembly 21, Figure 4 yes Figure 1 The top view of the sliding door 100 after the door body 20 is fully unfolded is shown. Figure 5 yes Figure 1The sliding door 100 shown is a top view of the door body 20 after it is fully folded. The sliding door 100 includes a hanging rail 10, a door body 20 and a drive assembly 30. The top of the door body 20 is hoisted on the hanging rail 10, and the door body 20 is slidably connected to the hanging rail 10. The door body 20 includes at least a first door row assembly 21 and a second door row assembly 22. The first door row assembly 21 and the second door row assembly 22 cooperate with each other. The first door row assembly 21 and the second door row assembly 22 can slide and expand in a first direction, or slide and fold in a second direction. The first direction and the second direction are opposite. The drive assembly 30 is connected to the first door row assembly 21, and the drive assembly 30 can drive the first door row assembly 21 to drive the second door row assembly 22 to slide.

[0040] like Figure 4 As shown, Figure 4 The door body 20 is shown to be fully extended along the first direction and slides to the closed position. The closed position refers to the position of the door body 20 when it is fully extended 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, vehicles, etc. from passing through. When the door body 20 is fully extended, the entire body is in an extended state. Figure 5 As shown, Figure 5 The door body 20 is shown to be completely retracted along the second direction and slid to the open position. The open position refers to the position of the door body 20 when the door body 20 is completely retracted along the second direction and away from the entrance and exit. At this time, the door body 20 makes way for the entrance and exit to allow pedestrians, vehicles, etc. to pass. After the door body 20 is completely retracted, the entire body is in a retracted state. Figure 4 and Figure 5 In the shown orientation, the first direction is to the left, and the second direction is to the right, and the first direction and the second direction are parallel to the length direction of the hanging rail 10 .

[0041] In the embodiment of the present invention, on the one hand, by hanging the top of the door body 20 on the hanging rail 10, the hanging rail 10 carries the door body 20 as a whole, 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 road surface or rails to slide, thereby avoiding the door row components from being affected by sand and stones on the ground or rails when sliding, and foreign matter such as sand and stones are difficult to enter the top hanging rail 10, and the sliding friction of the door row components (21, 22) on the hanging rail 10 is greater than the friction on the ground or rails. The smaller the size, the smoother the operation, and the stable operation of the door body 20 are ensured; on the other hand, all the door row components (21, 22) are hoisted on the same hanging rail 10, that is, all the door row components (21, 22) of the door body 20 only need one hanging rail 10 to be hoisted, and there is no need to separately set corresponding hanging rails 10 on each group of door row components (21, 22), which reduces the number of hanging rails 10 and the precision requirements for installing the hanging rails 10, thereby reducing the production cost of the sliding door 100 and the difficulty of on-site construction.

[0042] During the specific implementation process, the hanging rail 10 can be installed on the ceiling, the hanger or the door top frame, etc., so that the door body 20 is hung on the ceiling, the hanger or the door top frame as a whole.

[0043] In some embodiments, the door row components of the door body 20 are two groups, namely, the first door row components 21 and the second door row components 22. It is understandable that in other embodiments, the number of door row components of the door body 20 can be selected according to actual needs and is not limited to two groups. For example, the number of door row components is three groups, namely, the first door row components, the second door row components and the third door row components. The first door row components, the second door row components and the third door row components are sequentially linked and coordinated. The first door row components, the second door row components and the third door row components can slide and expand along the first direction to block the entrance and exit, or slide and close along the second direction to make the entrance and exit.

[0044] like Figures 2 to 4 As shown, in some embodiments, the first door row assembly 21 includes a first door row 211 and a first connecting member 212, one end of the first connecting member 212 is connected to the first door row 211, and the other end of the first connecting member 212 is slidably connected to the hanging rail 10, so that the first door row assembly 21 is hoisted on the hanging rail 10, and the hanging rail 10 supports the first door row 211 through the first connecting member 212, and the first door row 211 is slidably connected to the hanging rail 10 through the first connecting member 212, and the first door row 211 can slide along the first direction or the second direction on the hanging rail 10 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.

[0045] The second door row assembly 22 includes a second door row 221 and a second connecting member 222, one end of the second connecting member 222 is connected to the second door row 221, and the other end of the second connecting member 222 is slidably connected to the hanging rail 10, so that the second door row assembly 22 is hoisted on the hanging rail 10, and the hanging rail 10 supports the second door row 221 through the second connecting member 222, and the second door row 221 is slidably connected to the hanging rail 10 through the second connecting member 222, and the second door row 221 can slide along the first direction and the second direction on the hanging rail 10 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.

[0046] The first door row 211 and the second door row 221 are staggered with each other in the first direction and the second direction, so that the first door row 211 and the second door row 221 can avoid each other when sliding relative to each other, thereby avoiding movement interference between the first door row 211 and the second door row 221 when expanding or contracting; the first connecting member 212 and the second connecting member 222 are alternately arranged on the hanging rail 10, that is, the trajectories of the first connecting member 212 and the second connecting member 222 sliding along the hanging rail 10 are located on the same straight line. When the first door row 211 drives the first connecting member 212 to move in the first direction or the second direction, the first connecting member 212 can offset the second connecting member 222 to drive the second door row 221 to slide in the first direction or the second direction together. In this way, while realizing the hoisting of the first door row 211 and the second door row 221 to the hanging rail 10, the linkage between the first door row 211 and the second door row 221 is also realized. Its structure is simple, and there is no need to set up two separate structures for hoisting the door rows and for linking the door rows.

[0047] In the process of the driving component 30 driving the first door row component 21 to slide, the first connecting member 212 and the second connecting member 222 can offset each other to drive the second door row component 22 to slide together, so that the first door row component 21 and the second door row component 22 can slide together to the door closing position or the door opening position.

[0048] In the process of the driving component 30 driving the first door row component 21 to slide, the first connecting member 212 and the second connecting member 222 may also not abut against each other, so that the first door row component 21 slides relative to the second door row component 22, thereby realizing the expansion or folding of the door body 20.

[0049] In some embodiments, on a projection plane perpendicular to the first direction and the second direction, the first door row 211 and the second door row 221 are parallel to each other and spaced apart. In this way, the first door row 211 and the second door row 221 can be staggered along the first direction and the second direction, thereby allowing the first door row 211 and the second door row 221 to be expanded or folded.

[0050] In some other embodiments, the first door row 211 and the second door row 221 may also be arranged in other ways. For example, the first door row 211 is provided with a receiving cavity and a first cavity opening and a second cavity opening connected to the receiving cavity. The first cavity opening is set along the length direction of the upper side of the first door row 211, and the second cavity opening is set along the height direction of the left side or right side of the first door row 211. The second door row 221 is received in the receiving cavity. The first cavity opening is used to allow the second connecting member 222 to pass through and connect the hanging rail 10 and the second door row 221. The second cavity opening is used to allow the second door row 221 to extend out or retract into the receiving cavity. Through such an arrangement, the first door row 211 and the second door row 221 can be staggered with each other along the first direction and the second direction, thereby allowing the first door row 211 and the second door row 221 to be expanded or folded.

[0051] like Figure 4 and Figure 5 As shown, in some embodiments, a first connecting member 212 is provided at the left and right ends of the first door row 211, and a second connecting member 222 is provided at the left and right ends of the second door row 221. The first connecting members 212 on the first door row 211 and the second connecting members 222 on the second door row 221 are alternately arranged on the hanging rail 10, that is, the two first connecting members 212 and the two second connecting members 222 are alternately arranged in sequence on the hanging rail 10.

[0052] In this embodiment, each door row (211, 221) is hoisted on the hanging rail 10 through the connecting pieces (212, 222) on its left and right ends, so that the forces on the left and right ends of the door row (211, 221) are balanced when hung, preventing the door row (211, 221) from leaning to the left or right end due to uneven forces, thereby improving the stability of the door body 20 structure and the smoothness of the door body 20 during operation.

[0053] The following Figure 3 and Figure 4 The opening / closing process of the sliding door 100 of the embodiment shown is described as follows: Figure 4 As shown, when the door body 20 needs to make way for the entrance and exit, the driving assembly 30 can be used to drive the first door row 211 to slide in the second direction (to the right), so that the first door row 211 slides relative to the second door row 221 and moves closer to the right end of the second door row 221. At the same time, the first door row 211 drives the first connecting member 212 connected thereto to move relative to the second connecting member 222. At this time, the first connecting member 211 and the second connecting member 222 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 shown in FIG. Figure 5As shown, until the first connecting piece 212 on the left end of the first door row 211 slides to abut against the second connecting piece 222 on the left end of the second door row 221, and the first connecting piece 212 on the right end of the first door row 211 slides to abut against the second connecting piece 222 on the right end of the second door row 221, the first door row assembly 21 and the second door row assembly 22 are in a completely retracted state, and the first door row 211 can drive the second door row 221 to slide together in the second direction through the abutment between the first connecting piece 212 and the second connecting piece 222 until the door body 20 completely clears the entrance and exit.

[0054] like Figure 5 As shown, when the door body 20 is needed to block the entrance and exit, the first door row 211 can be pushed in the first direction (to the left) so that the first door row 211 slides relative to the second door row 221 and moves away from the right end of the second door row 221. At the same time, the first door row 211 drives the first connecting member 212 connected thereto to move relative to the second connecting member 222. At this time, the first connecting member 211 and the second connecting member 222 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 shown in FIG. Figure 4 As shown, until the first connecting member 212 on the right end of the first door row 211 slides to abut against the second connecting member 222 on the left end of the second door row 221, the first door row assembly 21 and the second door row assembly 22 are in a fully expanded state, and the first door row 211 can drive the second door row 221 to slide together along the first direction through the abutment of the first connecting member 212 and the second connecting member 222 until the door body 20 completely blocks the entrance and exit.

[0055] In some other embodiments, the number of first connecting members 212 and the location of the first connecting member 211 on the first door row 211 can be set according to actual needs, and the same applies to the second connecting member 222. For example, there are two first connecting members 212 and one second connecting member 222, and the two first connecting members 212 are respectively located at the left and right ends of the first door row 211, and one second connecting member 222 is located at the middle end of the second door row 221. On the hanging rail 10, the two first connecting members 212 are located on the left and right sides of the second connecting member 222. In order to maintain balance between the left and right ends of the second door row 221, the second connecting member 222 can be extended along the length of the hanging rail 10 (for example, the end of the second connecting member 222 connected to the hanging rail 10 can have multiple wheels arranged side by side along the length of the hanging rail 10). ; Or, the number of the first connecting member 212 is one, and the number of the second connecting member 222 is two, one first connecting member 212 is arranged at the middle end of the first door row 211, and the two second connecting members 222 are arranged at the left and right ends of the second door row 221. On the hanging rail 10, the two second connecting members 222 are located on the left and right sides of the first connecting member 212, wherein, in order to keep the left and right ends of the first door row 211 balanced, the first connecting member 212 can be extended along the length direction of the hanging rail 10 (for example, the end of the first connecting member 212 connected to the hanging rail 10 can have multiple wheels arranged side by side along the length direction of the hanging rail 10).

[0056] like Figures 1 to 3 As shown, in some embodiments, the hanging rail 10 is provided with a hanging groove 11, a first load-bearing flange 12 and a second load-bearing flange 13 along its own length direction, the notch of the hanging groove 11 faces downward, and the first load-bearing flange 12 and the second load-bearing flange 13 are spaced apart at the front and rear sides of the notch of the hanging groove 11. One end of the first connecting member 212 and one end of the second connecting member 222 are respectively accommodated in the hanging groove 11, and the first bearing flange 12 and the second bearing flange 13 support the first connecting member 212 and the second connecting member 222 in the vertical direction, and the other end of the first connecting member 212 and the other end of the second connecting member 222 extend from the notch of the hanging groove 11 respectively, and the first bearing flange 12 and the second bearing flange 13 are against the first connecting member 212 and the second connecting member 222 in the horizontal direction to prevent the first connecting member 212 and the second connecting member 222 from being offset forward and backward relative to the first bearing flange 12 and the second bearing flange 13, thereby resisting the first door row assembly 21 and the second door row assembly 22 from shaking forward and backward relative to the hanging rail 10, thereby improving the stability of the door body 20 structure and the stability of the door body 20 during operation.

[0057] The first connecting member 212 includes a first hanging wheel 2121 and a first connecting portion 2122. The first hanging wheel 2121 is accommodated in the hanging groove 11 and abuts against the first bearing flange 12 and the second bearing flange 13. The first hanging wheel 2121 can slide in the hanging groove 11 along the first direction or the second direction. The first bearing flange 12 and the second bearing flange 13 carry the first hanging wheel 2121 in the vertical direction. One end of the first connecting portion 2122 is connected to the first hanging wheel 2121, and the other end of the first connecting portion 2122 extends from the notch of the hanging groove 11 and is connected to the first door row 211. The first bearing flange 12 and the second bearing flange 13 abut against the first connecting portion 2122 from the front and back sides respectively.

[0058] The second connecting member 222 includes a second hanging wheel 2221 and a second connecting part 2222. The second hanging wheel 2221 is accommodated in the hanging groove 11 and abuts against the first bearing flange 12 and the second bearing flange 13. The second hanging wheel 2221 can slide in the hanging groove 11 along the first direction or the second direction. The first bearing flange 12 and the second bearing flange 13 carry the second hanging wheel 2221 in the vertical direction. One end of the second connecting part 2222 is connected to the second hanging wheel 2221, and the other end of the second connecting part 2222 extends from the notch of the hanging groove 11 and is connected to the second door row 221. The first bearing flange 12 and the second bearing flange 13 abut against the second connecting part 2222 from the front and back sides respectively.

[0059] It is understood that, on a projection plane perpendicular to the first and second directions, the other end of the first connecting portion 2122 and the other end of the second connecting portion 2222 extend out of the notch of the hanging groove 11 and extend in different directions, so that the first door row 211 and the first connecting portion 2122, as well as the second door row 221 and the second connecting portion 2222, can be staggered on the projection plane after being connected, thereby avoiding motion interference between the first door row 211 and the second door row 221 when sliding in the first or second direction. The first connecting portion 2122 extends downward to connect with the first door row 211, so that the first door row 211 connected to the first connecting portion 2122 is located directly below the hanging groove 11; the second connecting portion 2222 extends toward the front or rear side and then extends downward to connect with the second door row 221, so that the second door row 221 connected to the second connecting portion 2222 is located below the hanging groove 11.

[0060] Of course, the first connecting part 2122 can also extend toward the front or rear side and then extend downward to connect with the first door row 211, so that the first door row 211 connected with the first connecting part 2122 is located below the hanging groove 11; the second connecting part 2222 can also extend downward to connect with the second door row 221, so that the second door row 221 connected with the second connecting part 2222 is located directly below the hanging groove 11.

[0061] Optionally, the first connection portion 2122 is in a straight rod shape, and the second connection portion 2222 is in a right-angle shape; or, the first connection portion 2122 is in a right-angle shape, and the second connection portion 2222 is in a straight rod shape.

[0062] See also Figures 6 to 9 , Figure 6 This is a front view of a sliding door 100 provided in another embodiment of the present invention. Figure 7 yes Figure 6 The side view of the sliding door 100 shown in FIG. Figure 8 yes Figure 6 The top view of the sliding door 100 after the door body 20 is fully unfolded is shown. Figure 9 yes Figure 6 The shown is a top view of the sliding door 100 after the door body 20 is fully retracted. In some embodiments, the first door row assembly 21 includes a first door row 211 and a first connecting member 212. One end of the first connecting member 212 is connected to the first door row 211, and the other end of the first connecting member 212 is slidably connected to the hanging rail 10. In this way, the first door row assembly 21 is hoisted on the hanging rail 10. The hanging rail 10 supports the first door row 211 through the first connecting member 212, and the first door row 211 is slidably connected to the hanging rail 10 through the first connecting member 212. The first door row 211 can slide on the hanging rail 10 along the first direction or the second direction 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.

[0063] The second door row assembly 22A includes a second door row 221A and a second connecting member 222A, and the second connecting member 222A is slidably connected to the first door row 211 and the second door row 221A. In this way, the second door row 221A can slide relative to the first door row assembly 211 through the second connecting member 222A to realize the expansion or folding of the door body 20. The first door row 211 supports the second door row 221A through the second connecting member 222A. The first door row 211 can drive the second door row 221A to slide along the first direction or the second direction through the second connecting member 222A, so that the second door row 221A can slide without relying on the support of the ground or the rails.

[0064] The first door row 211 and the second door row 221A are staggered along the first direction and the second direction so that the first door row 211 and the second door row 221A can avoid each other when sliding relative to each other, thereby avoiding movement interference between the first door row 211 and the second door row 221A when expanding or contracting.

[0065] In this embodiment, the first door row 211 is hoisted to the hanging rail 10 through the first connecting member 212, and the second door row 221A is indirectly hoisted to the hanging rail 10 through the second connecting member 222A. When the driving component 30 drives the first door row 211 to slide, the second door row 221A can slide into place together with the first door row 211 through the second connecting member 222A, and the second door row 221A can also slide relative to the first door row 211 through the second connecting member 222A to expand or fold the door body 20. Its structure is simple, and there is no need to set up two separate structures for hoisting the second door row 221A and for linking the second door row 221A.

[0066] In some embodiments, the second connecting member 222A is located between the first door row 211 and the second door row 221A; one end of the second connecting member 222A is connected to the first door row 211, and the other end of the second connecting member 222A extends into the second door row 221A and is slidingly connected to the second door row 221A, or, one end of the second connecting member 222A is connected to the second door row 221A, and the other end of the second connecting member 222A extends into the first door row 211 and is slidingly connected to the first door row 211. By extending the other end of the second connecting member 222A into the corresponding door row (211, 221A), part of the structure of the second connecting member 222A can be accommodated, and there is no need to reserve an excessively large gap between the two door rows (211, 221A), thereby reducing the gap between the two door rows (211, 221A), preventing people's hands from being accidentally pinched in the gap between the two door rows (211, 221A), and reducing the front and rear occupied space of the door body 20; and, after the other end of the second connecting member 222A is extended into the door row (211, 221A), the suspension force arm of the second connecting member 222A between the two door rows (211, 221A) is shortened, thereby improving the connection strength between the first door row 211 and the second door row 221A, so that the door body 20 can operate more smoothly.

[0067] In some embodiments, there are at least four second connecting members 222A, wherein one end of at least two second connecting members 222A are respectively fixedly connected to the upper and lower parts of the right end of the first door row 211, and the other ends are respectively slidably connected to the second door row 221A, and another one end of at least two second connecting members 222A are respectively fixedly connected to the upper and lower parts of the left end of the second door row 221A, and the other ends are respectively slidably connected to the first door row 211. Through the above arrangement, the first door row 211 has support points for the second door row 221A distributed in the four corners of a rectangle. During the sliding of the second door row 221A relative to the first door row 211, the second door row 221A can always be guaranteed to firmly support the first door row 211, which can effectively prevent the second door row 221A from shaking relative to the first door row 211. In addition, the second connecting member 222A is arranged at the end of the door row (211, 221A), which can reduce the overlapping part of the first door row 211 and the second door row 221A in the front-to-back direction after the door body 20 is fully expanded, thereby making the door body 20 as long as possible after it is fully expanded, and increase the overlapping part of the first door row 211 and the second door row 221A in the front-to-back direction after the door body 20 is fully folded, thereby making the door body 20 as short as possible after it is fully folded.

[0068] In some embodiments, a slide groove 201 is provided at the upper and lower portions of the first door row 211 and the upper and lower portions of the second door row 221A. The slide groove at the upper portion of the first door row 211 is opposite to the slide groove at the upper portion of the second door row 221A, and the slide groove at the lower portion of the first door row 211 is opposite to the slide groove at the lower portion of the second door row 221A. At least two second connecting members 222A have one end fixedly connected to the upper and lower slide grooves 201 of the first door row 211, respectively, and the other end slidably connected to the upper and lower slide grooves 201 of the second door row 221, respectively. In addition, at least two second connecting members 222A have one end fixedly connected to the upper and lower slide grooves 201 of the second door row 221, respectively, and the other end slidably connected to the upper and lower slide grooves 201 of the first door row 211, respectively. By opening the slide groove 201 at the same position of each door row (211, 221A), the universality of the structure of the door row (211, 221A) can be ensured and the production cost can be reduced. In addition, the two ends of the second connecting member 222A respectively extend into the slide groove 201 of the corresponding door row (211, 221A), which can reduce the shear force arm of the second connecting member 222A between the door rows (211, 221A) and improve the shear resistance of the second connecting member 222A on the door row (211, 221A).

[0069] In some embodiments, a first limiting flange 2011 and a second limiting flange 2012 are provided at the notch of the chute 201 for limiting the other end of the corresponding second connector 222A from being separated from the notch. The first limiting flange 2011 and the second limiting flange 2012 are spaced apart from each other. Through the above arrangement, the first limiting flange 2011 and the second limiting flange 2012 can abut against the other end of the second connector 222A in the horizontal direction, thereby limiting the second connector 222A from being separated from the notch of the corresponding chute 201. In addition, the second limiting flange 2012 can also abut against the second connector 222A in the vertical direction to support the second connector 222A, thereby improving the stability of the connection between the first door row assembly 21 and the second door row assembly 22.

[0070] Specifically, the second connecting member 222A includes a second hanging wheel 2221A and a second connecting part 2222A. In the two relative slide grooves 201, the second hanging wheel 2221A is accommodated in a corresponding slide groove 201, one end of the second connecting part 2222A is accommodated in the corresponding other slide groove 201 and fixed, and the other end of the second connecting part 2222A is connected to the second hanging wheel 2221A. The first limiting flange 2011 and the second limiting flange 2012 are horizontally opposed to the second hanging wheel 2221A to limit the second connecting part 2222A from detaching from the slot of the slide groove 201. The second limiting flange 2012 also vertically opposes the second connecting part 2222A to support the second connecting part 2222A.

[0071] In some embodiments, the sliding door 100 also includes a stop member 40, which is used to limit the door body 20 from continuing to slide in the first direction when the door body 20 slides to the closed position, and to limit the door body 20 from continuing to slide in the second direction when the door body 20 slides to the open position. The stop member 40 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 into place and deviating from the closed position or the open position.

[0072] like Figure 8 and Figure 9 As shown, in some embodiments, there are two stoppers 40, which are respectively located on the left and right sides of the second door row 221A. When the first door row assembly 21 drives the second door row assembly 22A to slide along the first direction to the closed position, the left stopper 40 abuts against the left end of the second door row 221A, thereby preventing the first door row assembly 21 from continuing to drive the second door row assembly 22A to slide along the first direction, so that the first door row assembly 21 and the second door row assembly 22A remain in the closed position in the expanded state; Figure 9As shown, when the first door row assembly 21 drives the second door row assembly 22A to slide along the second direction to the door-opening position, the stopper 40 on the right side abuts against the right end of the second door row 221A, thereby preventing the first door row assembly 21 from continuing to drive the second door row assembly 22A to slide along the second direction, so that the first door row assembly 21 and the second door row assembly 22A remain in the door-opening position in a folded state.

[0073] During specific implementation, the stopper 40 can be set on the ceiling, the hanger or the door top frame.

[0074] The following Figure 8 and Figure 9 The opening / closing process of the sliding door 100 of the embodiment shown is described as follows: Figure 8 As shown, when the door body 20 is required to make way for the entrance and exit, the first door row 211 can be driven by the driving assembly 30 to slide along the second direction (to the right). In an ideal movement process, the first door row 211 can move relative to the second door row 221, while the second door row assembly 22 as a whole remains in the initial position when blocking the entrance and exit, as shown in FIG. Figure 9 As shown, until the second connecting member 222A fixed on the first door row 211 abuts against the right end position of the second door row 221, and the second connecting member 222A fixed on the second door row 221 abuts against the left end position of the first door row 211, the first door row 211 and the second door row 221 are in a completely retracted state, and the first door row 211 can drive the second door row 221 to slide together in the second direction through each second connecting member 222A until the right end of the second door row 221A abuts against the stop member 40 on the right side, and the door body 20 stops moving and completely clears the entrance and exit. Among them, during the actual movement process, when the driving component 30 drives the first door row component 211 to move along the second direction, the second door row 221 may move with the first door row 211 under the friction force of the second connecting member 222A, and the first door row 211 and the second door row 221 move together along the second direction while maintaining an expanded state or a certain degree of contraction state until the left end of the second door row 221A abuts against the stop member 40 on the left, the second door row 221A stops moving, and the first door row 211 continues to move along the second direction until the second connecting member 222A fixed on the first door row 211 abuts against the right end position of the second door row 221, and when the second connecting member 222A fixed on the second door row 221 abuts against the left end position of the first door row 211, the door body 20 stops moving and completely clears the entrance and exit.

[0075] like Figure 9As shown, when the door body 20 is needed to block the entrance and exit, the first door row 211 can be driven by the driving assembly 30 to slide along the first direction (to the left). In the ideal movement process, the first door row 211 can move relative to the second door row 221, while the second door row assembly 22 as a whole remains in the initial position when the entrance and exit are made clear, as shown in FIG. Figure 8 As shown, until the second connecting member 222A fixed on the first door row 211 abuts against the left end position of the second door row 221, and the second connecting member 222A fixed on the second door row 221 abuts against the right end position of the first door row 211, the first door row 211 and the second door row 221 are in a fully expanded state, and the first door row 211 can drive the second door row 221 to slide together along the first direction through each second connecting member 222A until the left end of the second door row 221A abuts against the stop member 40 on the left, and the door body 20 stops moving and completely blocks the entrance and exit. In which, during the actual movement process, when the driving component 30 drives the first door row component 211 to move along the first direction, the second door row 221 may move with the first door row 211 under the friction force of the second connecting member 222A, and the first door row 211 and the second door row 221 move together along the first direction while maintaining a retracted state or a certain degree of expansion, until the left end of the second door row 221A abuts against the stop member 40 on the left, the second door row 221A stops moving, and the first door row 211 continues to move along the first direction until the second connecting member 222A fixed on the first door row 211 abuts against the left end position of the second door row 221, and the second connecting member 222A fixed on the second door row 221 abuts against the right end position of the first door row 211, the door body 20 stops moving and completely clears the entrance and exit.

[0076] In some embodiments, the drive assembly 30 includes a drive motor 31 and a transmission mechanism 32. The drive motor 31 is connected to the transmission mechanism 32, and the transmission mechanism 32 is connected to the first door row assembly 21. When the drive motor 31 is started, the transmission mechanism 32 can be driven to move. The transmission mechanism 32 drives the first door row assembly 21 to drive the second door row assembly 22 to expand in a first direction or to retract in a second direction.

[0077] The transmission mechanism 32 includes two pulleys 321, a belt 322 and a driving member 323. The two pulleys 321 are arranged at intervals in a direction parallel to the hanging rail 10. The belt 322 is wound around the two pulleys 321. One end of the driving member 323 is connected to the belt 322, and the other end of the driving member 323 is connected to the first door row assembly 21. The output shaft of the drive motor 31 is connected to one of the two pulleys 321.

[0078] When the drive motor 31 is started and the pulley 321 on the left rotates in the clockwise direction, the pulley 321 on the left drives the belt 322 to run clockwise around the two pulleys 321. At the same time, the belt 322 drives the first door row assembly 21 through the driving member 323 to drive the second door row assembly 22 to slide and unfold in the first direction; when the drive motor 31 is started and the pulley 321 on the left rotates in the counterclockwise direction, the pulley 321 on the left drives the belt 322 to run counterclockwise around the two pulleys 321. At the same time, the belt 322 drives the first door row assembly 21 through the driving member 323 to drive the second door row assembly 22 to slide and fold in the second direction.

[0079] In some other embodiments, the pulley 321 can be replaced by a sprocket, and the belt 322 can be replaced by a chain, which is wound around the two sprockets; or, the pulley 321 can be replaced by a drum, and the belt 322 can be replaced by a wire rope, and the drive motor 31 drives the drum to rotate to retract and release the wire rope, thereby driving the first door row assembly 21 to slide.

[0080] In some other embodiments, the transmission mechanism may also be other components that can transmit motion between the drive motor 31 and the door body 20. For example, the transmission component includes a gear and a rack. The gear is connected to the output end of the drive motor 31, the rack is parallel to the hanging rail 10, and the rack is arranged on the first door row component 21. The gear is engaged with the rack, and starting the drive motor 31 can make the gear rotate, so that the gear drives the rack first door row component 21 to drive the second door row component 22 to move.

[0081] Please refer back Figure 2 and Figure 3 In some embodiments, the sliding door 100 also includes a guide rail 50, the length direction of the guide rail 50 is arranged parallel to the length direction of the hanging rail 10, and the bottom of the first door row assembly 21 and / or the bottom of the second door row assembly 22 is slidably connected to the guide rail 50. In this way, the bottom of the door body 20 can be guided when the door body 20 slides, so that the door body 20 can maintain a stable state up and down when sliding, and the guide rail 50 can play a front and rear limiting role at the bottom of the door body 20, preventing the bottom of the door body 20 from shaking back and forth relative to the top, improving the wind resistance of the door body 20, and ensuring the stability and service life of the door body 20 during operation; and the hanging rail 10 and the guide rail 50 are located in the same vertical plane. In this way, the torque generated by the door body 20 between the hanging rail 10 and the guide rail 50 can be reduced, thereby avoiding stress deformation at the connection between the door body 20 and the hanging rail 10 and the connection between the door body 20 and the guide rail 50, thereby improving the structural stability of the door body 20.

[0082] In some embodiments, the guide rail 50 includes a first limit plate 51 and a second limit plate 52, which are parallel to each other and spaced apart. The first door row assembly 21 also includes a first guide member 213, which includes a first guide wheel 2131 and a first guide rod 2132. The first guide wheel 2131 is located between the first limit plate 51 and the second limit plate 52, and the circumferential outer side wall of the first guide wheel 2131 abuts against the first limit plate 51 and the second limit plate 52. One end of the first guide rod 2132 is connected to the bottom of the first door row 211, and the other end of the first guide rod 2132 is connected to the first guide wheel 2131; and / or Alternatively, the second door row assembly 22 also includes a second guide member 223, the second guide member 223 includes a second guide wheel 2231 and a second guide rod 2232, the second guide wheel 2231 is located between the first limiting plate 51 and the second limiting plate 52, and the circumferential outer wall of the second guide wheel 2231 is against the first limiting plate 51 and the second limiting plate 52, one end of the second guide rod 2232 is connected to the bottom of the second door row 221, and the other end of the second guide rod 2232 is connected to the second guide wheel 2231. Through the above arrangement, the first limiting plate 51 and the second limiting plate 52 can respectively abut against the guide wheels (2131, 2231) to limit the guide member (213, 223) from moving forward and backward relative to the guide rail 50, thereby preventing the bottom of the door body 20 from shaking forward and backward relative to the top, and the guide wheels (2131, 2231) can slide between the first limiting plate 51 and the second limiting plate 52, thereby reducing the friction generated between the guide wheels (2131, 2231) and the first limiting plate 51 and the second limiting plate 52.

[0083] During specific implementation, the guide rail 50 can be laid on or under the road surface.
