For example, in the Figure 1 , the second door body 200 is closed when moving to the right and opened when moving to the left, and the end of the second door body 200 on the right is referred to as the front end, and the end on the left is referred to as the rear end. The definitions of the front end and the rear end of the first door body 100 are the same. Figure 2

[0107] Figure 1 is a schematic diagram of the overall structure of a sliding door according to an exemplary embodiment of the present disclosure, Figure 2 is a schematic diagram of the rear view structure of the sliding door of Figure 1 , Figure 3 is a schematic diagram of the right view structure of the sliding door of Figure 1 , Figure 4 is a schematic diagram of the partial structure of the sliding door of Figure 1 , Figure 4A is a schematic diagram of the right view structure of Figure 4 , Figure 4B is a partial enlarged view of e in Figure 4A , Figure 4C is a partial enlarged view of f in Figure 4A . Referring to Figures 1 to 4C , the sliding door provided by the present embodiment includes a rack, a first door body 100, a motor 400 in driving connection with the first door body 100, and a second door body 200 driven by the first door body 100. When the motor 400 (see Figure 5 ) drives the first door body 100 to slide, the first door body 100 can drive the second door body 200 to move in linkage, wherein the rack includes a gantry 700 and a stand column 650. The first door body 100 can drive the second door body 200 to move in linkage through a transmission mechanism such as a ring mechanism H (see Figure 20 , Figure 21 ), and the second door body 200 can slide on the first door body 100 in the longitudinal direction, realizing the suspended movement of the second door body 200, without the need to pre-bury guide rails on the ground, thus being convenient to install and having more stable performance. Between the first door body 100 and the second door body 200, two sliding connecting pieces 309 and 310 (see Figure 3 , Figure 8 and Figure 9 ) can be arranged at the bottom in the longitudinal direction, and two sliding connecting pieces 319 and 320 can be arranged at the top in the longitudinal direction to realize the connection between the door bodies (see Figure 3 , Figure 8 and Figure 9 ​) In the open door state, the first door body 100 and the second door body 200 substantially overlap each other, when the motor 400 drives the first door body 100 to move, the first door body 100 drives the connected second door body 200 to slide forward relative to the first door body 100 through the transmission mechanism such as the ring mechanism H, the overlapping part of the first door body 100 and the second door body 200 gradually becomes smaller, when the first door body 100 and the second door body 200 run to the closed door state, the overlapping part of the first door body 100 and the second door body 200 becomes the smallest, at this time, the closed door width is the largest. In this way, after the first door body 100 and the second door body 200 are connected, linkage can be realized through the ring mechanism H, when the door is opened, the two door bodies substantially overlap each other, which can reduce the door body retreat space; when the door is closed, the overlapping part of the two door bodies is the smallest, which can increase the closed door width.

[0108] Referring to Figure 2 , the first door body 100 and the second door body 200 are arranged in parallel, the first door body 100 includes a door body slide rod 180 arranged at the longitudinal bottom and a door body slide rod 110 arranged at the longitudinal top, the door body slide rod 180 can be used as a support beam of the first door body 100, the door body slide rod 110 and the door body slide rod 180 extend along the movement direction of the first door body 100, a plurality of longitudinal connecting columns 230 are arranged between the door body slide rod 180 and the door body slide rod 110 of the first door body 100, and the connecting columns 230 are arranged in the transverse direction at intervals; the second door body 200 includes a door body slide rod 181 arranged at the longitudinal bottom and a door body slide rod 210 arranged at the longitudinal top, the door body slide rod 181 can be used as a support beam of the second door body 200, the door body slide rod 181 and the door body slide rod 210 extend along the movement direction of the second door body 200, a plurality of longitudinal connecting columns 230 are arranged between the door body slide rod 181 and the door body slide rod 210 of the second door body 200, and the connecting columns 230 are arranged in the transverse direction at intervals.

[0109] Figure 5 is Figure 1 a partial sectional view of the gantry at the translating door. Referring to Figure 5 , the first door body 100 is driven by the motor 400 through the gear 410, the motor 400 is fixed on the gantry 700 and is fixed relative to the ground, the rack 140 is fixedly installed on the door body slide rod 180 of the first door body 100, the rack 140 is arranged along the length direction of the door body slide rod 180 (i.e. the transverse direction), the gear 410 at the output end of the motor 400 and the rack 140 on the door body slide rod are engaged with each other for power transmission, so as to drive the first door body 100 to run. It should be noted that in other embodiments, the motor 400 can also be installed on the door body slide rod 180 of the first door body 100, and the rack 140 is fixed to the ground; other transmission modes such as friction wheel transmission mode can also be used, and the transmission mode of the motor 400 and the first door body 100 is not limited in the disclosure.

[0110] Referring to Figure 4The rack comprises a first support and a second support spaced apart from the first support in a transverse direction. The first support is a portal frame 700, and the second support is a column 650. The sliding support 510 and the sliding support 530 are spaced apart in a longitudinal direction and integrally assembled to the first support, and the sliding support 520 and the sliding support 540 are spaced apart in the longitudinal direction and integrally assembled to the second support. The sliding support 510 and the sliding support 520 arranged at the longitudinal bottom end of the first door body 100 are connected by a connecting piece 940. The first door body 100 is slidable relative to the rack under the support of the sliding supports 510, 520 at the longitudinal bottom and the sliding supports 530, 540 at the longitudinal top.

[0111] Figure 6 is Figure 4 an enlarged view of the sliding support 510 shown in Figure 4 and Figure 6 In this embodiment, the sliding support 510 and the sliding support 520 are fixed relative to the ground. The mounting mode of the sliding support 510 is described by way of example.

The pulley sets of the sliding support 510 and the sliding support 520 are integrally accommodated in the cavity 111. The cavity 111 limits the pulley sets of the sliding support 510 and the sliding support 520, so as to prevent the pulley sets of the sliding support 510 and the sliding support 520 from being separated from the cavity 111, and further to lock the pulley sets of the sliding support 510 and the sliding support 520 to slide in the cavity 111.

[0113] In this disclosure, “locking” refers to limiting the degrees of freedom of the door body, so that the door body can only move in the sliding direction thereof.

[0114] Figure 5 and Figure 6The cooperation relationship between the sliding support 510 and the cavity 111 is described. The inner wall of the cavity 111 includes a top wall, a bottom wall, and two side walls connecting the top wall and the bottom wall, and the opening is arranged at the middle of the bottom wall. The sliding support 510 includes two groups of bearing wheels 512 and two groups of guide wheels 513. The two groups of bearing wheels 512 of the sliding support 510 abut against the top wall and the bottom wall of the cavity 111 and slide in contact with the top wall and the bottom wall of the cavity 111 to realize the longitudinal support of the first door body 100. The two groups of guide wheels 513 slide in contact with the two side walls of the cavity 111 to realize the lateral limiting of the first door body 100. After such arrangement, the sliding support 510 slides in contact with the inner wall of the cavity 111 through the bearing wheels 512 and the guide wheels 513, so that the first door body 100 slides more stably on the sliding support 510, the first door body 100 slides more freely, and the operation noise of the first door body 100 is reduced. It should be noted that the cooperation relationship between the sliding support 520 and the cavity 111 can refer to the description of the cooperation between the sliding support 510 and the cavity 111, which will not be described here. The pulley sets of the sliding support 510 and the sliding support 520 are locked in the cavity 111 and slide. After such arrangement, the pulley sets are not exposed, the hidden arrangement of the pulley sets is realized, and the appearance effect of the sliding door is improved.

[0115] The sliding support 530 and the sliding support 540 are arranged between the rack and the longitudinal top of the first door body 100, that is, the sliding support 530 is arranged between the portal frame 700 and the longitudinal top of the first door body 100, and the sliding support 540 is arranged between the column 650 and the longitudinal top of the first door body 100. The sliding support 530 and the sliding support 540 can have the same structure. Figure 7 Figure 4 is an enlarged view of the sliding support 540 shown in FIG. 6B. With reference to FIGS. 6B and 6C, the sliding support 540 can include a connecting arm 324, a fixed connecting end 321 and a sliding connecting end 322 arranged at two ends of the connecting arm 324, and at least one guide wheel 323 arranged at the sliding connecting end 322. It can be understood that in other embodiments, the sliding support 530 and the sliding support 540 can have different structures. Figure 7

[0116] Figures 4A to 4C ​​​The first door body 100 is provided with a cavity 113 on the side opposite to the sliding support 530 and 540, the cavity 113 includes a top wall, a bottom wall and two side walls, one side wall of the cavity 113 is provided with an opening for the connecting arm 324 to pass through, the fixed connecting end 321 of the sliding support 540 is fixedly connected with the vertical column 650, and the sliding connecting end 322 extends into the cavity 113 from the opening of the cavity 113 and is locked in the cavity 113. The cavity 113 limits the sliding connecting end 322, which can prevent the sliding connecting end 322 from being separated from the cavity 113, and then the sliding connecting end 322 of the sliding support 540 is locked in the cavity 113 to support the first door body 100 to slide. The guide wheel 323 of the sliding connecting end 322 of the sliding support 540 is limited between the two side walls of the cavity 113 and in sliding contact with the side walls. Through such a design, the sliding support 540 can be guided and supported when being locked in the first door body 100 to slide. Similarly, the fixed connecting end of the sliding support 530 can be fixed to one side beam 740 of the gantry 700, and the sliding connecting end can be locked in the cavity 113 of the first door body 100 to support the first door body 100 to slide.

[0117] In the embodiment, four sliding connection points are formed between the rack and the first door body 100 through the sliding supports 510 and 520 and the sliding supports 530 and 540. The four sliding connection points can more stably support the first door body 100 to slide relative to the rack in the longitudinal and lateral directions, and can better ensure the stability of the installation of the first door body 100. It can be understood that the number of sliding connection points is not limited in the disclosure, and more than four sliding connection points can be provided on the rack to support the first door body 100 to slide. After the sliding supports 510 and 520 support the first door body 100 in the longitudinal direction, the sliding supports 530 and 540 can no longer bear the gravity of the first door body 100, and therefore the sliding connecting end 322 of the sliding supports 530 and 540 can only be provided with the guide wheel 323 in sliding contact with the side walls of the cavity 113. Such a design simplifies the structure of the sliding supports 530 and 540, and can more conveniently assemble the first door body 100 on the rack 700. The first door body 100 includes a door body slide rod 180 at the lower part of the first door body 100 and a door body slide rod 110 at the upper part of the first door body 100, the cavity 111 is arranged in the door body slide rod 180 at the bottom of the first door body 100, and the cavity 113 is arranged in the door body slide rod 110 at the top of the first door body 100. The sliding supports 510 and 520 and the sliding supports 530 and 540 are hiddenly installed by fully utilizing the internal structure and space of the first door body 100, which is more stable in structure and improves the appearance effect of the sliding door.

See Figure 4 and Figure 4D In this embodiment, the sliding support 510 and the sliding support 520 can be assembled into one body through the connecting piece 940, the sliding support 520 and the sliding support 540 can be assembled into one body with the stand 650, and the gantry 700, the sliding support 510 and the sliding support 530 can be assembled into one body.

After the sliding door is formed into an integral assembly structure, it is packaged and transported. At the installation site of the sliding door, the integrated door body is only placed at the position to be installed, and the fixed plates 730 and 731 are fixed to the ground by chemical anchors or expansion screws, so that the sliding door can be fixed to the ground as a whole. Therefore, the process at the installation site is simple, convenient and fast.

[0119] Figure 8 is Figure 2 the left view of the sliding door shown, Figure 9 is Figure 2 the right view of the sliding door shown. See Figure 8 and Figure 9 , two sliding connecting pieces 309 and 310 are arranged at the longitudinal bottom between the first door body 100 and the second door body 200, and two sliding connecting pieces 319 and 320 are arranged at the longitudinal top, so that the connection of the first door body 100 and the second door body 200 can be realized.

In this embodiment, the second door body 200 is only supported by the first door body 100. After the first door body 100 and the second door body 200 are connected, the sliding connecting pieces 309 and 310 arranged at the longitudinal bottom play a role in supporting the second door body 200 in the longitudinal direction, so that the suspended installation of the second door body 200 is realized. The second door body 200 is slidably supported on the first door body 100 in the longitudinal direction, so that the suspended operation of the second door body 200 is realized, and the ground pre-buried guide rail is not needed, so that the installation is convenient and the performance is more stable. It should be noted that the structures of the sliding connecting pieces 319 and 320 can be the same as those of the sliding support 530 and the sliding support 540, but are not limited thereto.

Referring to Figures 8 to 11 , for example, referring to Figure 8A , the sliding connection end 312 of the sliding connection piece 310 extends into and is locked in the cavity 112 from the opening of the cavity 112 of the first door body 100, and the fixed connection end 311 extends into and is fixed in the cavity 411 from the opening of the cavity 411 of the second door body 200; referring to Figure 9A , the sliding connection end 312 of the sliding connection piece 309 extends into and is locked in the cavity 411 from the opening of the cavity 411 of the second door body 200, and the fixed connection end 311 extends into and is fixed in the cavity 112 from the opening of the cavity 112 of the first door body 100; referring to Figure 8B , the sliding connection end 322 of the sliding connection piece 320 extends into and is locked in the cavity 114 from the opening of the cavity 114 of the first door body 100, and the fixed connection end 321 is fixed to the rear end of the second door body 200; referring to Figure 9B , the sliding connection end 322 of the sliding connection piece 319 extends into and is locked in the cavity 412 from the opening of the cavity 412 of the second door body 200, and the fixed connection end 321 is fixed to the front end of the first door body 100.

[0122] In this embodiment, the sliding connection end 312 of the sliding connection piece 309 is locked in the cavity 411 of the second door body to support the sliding of the second door body 200 relative to the first door body 100, and the sliding connection end 312 of the sliding connection piece 310 is locked in the cavity 112 of the first door body 100 to support the sliding of the first door body 100 relative to the second door body 200. This configuration is referred to as the interlocking arrangement of two sliding connection pieces. In this embodiment, the first door body 100 and the second door body 200 are connected by the interlocking arrangement of two sliding connection pieces at the longitudinal bottom. Similarly, the sliding connection end 322 of the sliding connection piece 319 is locked in the cavity 412 of the second door body 200 to support the sliding of the second door body 200 relative to the first door body 100, and the sliding connection end 322 of the sliding connection piece 320 is locked in the cavity 114 of the first door body to support the sliding of the first door body 100 relative to the second door body 200. In this way, the first door body 100 and the second door body 200 are connected by the interlocking arrangement of two sliding connection pieces at the longitudinal top.

[0123] The cavities 112, 114, 411, and 412 can effectively utilize the internal space and structure of the first door body 100 and the second door body 200, and can realize the hidden installation of the sliding connection pieces 309, 310, 319, and 320, which is conducive to improving the appearance of the sliding door and better ensuring the sliding stability of the sliding connection pieces 309, 310, 319, and 320.

[0125] FIG. 9 shows a top view of the sliding connection piece in FIG. 7. The sliding connection piece 310 includes two load wheels and two groups of lateral guide wheels. Figures 12A-12C ​The sliding connecting piece 309 comprises a fixed connecting end 311 and a sliding connecting end 312; the sliding connecting end 312 comprises a guide wheel connecting rod 315, which is rotationally connected with the connecting arm 314, and the guide wheel connecting rod 315 can swing longitudinally around the connecting arm 314. The guide wheel connecting rod 315 is rotationally connected with different load wheels 313 through different guide shafts 402, and the load wheels 313 are used for supporting the longitudinal stress of the door body. That is, the guide wheel connecting rod 315 is provided with two or more guide shafts 402, and each guide shaft 402 is provided with a load wheel 313 for supporting the longitudinal stress of the door body. The axial direction of the load wheel 313 is parallel to the horizontal extension direction of the connecting arm 314; the radial direction of the load wheel 313 is parallel to the longitudinal connecting surface of the connecting arm 314 connected with the fixed connecting end 311, and the fixed connecting end 311 and the sliding connecting end 312 are located on an approximately horizontal plane, so that the sliding connecting piece 309 can laterally connect two door bodies and support one door body to support another connected door body. The guide wheel connecting rod 315 is rotationally connected with the connecting arm 314; the fixed connecting end 311 is fixedly connected with the connecting arm 314; and the guide wheel connecting rod 315 of the sliding connecting end 312 further comprises a lateral guide wheel 333, which can be used for lateral guiding and supporting and adjusting the lateral distance of the door body, and the axial direction of the lateral guide wheel 333 is perpendicular to the axial direction of the load wheel 313. In the embodiment, the diameter of the lateral guide wheel 333 is greater than the width of the load wheel 313 and slightly greater than the width of the guide wheel connecting rod 315 (see FIG. 6), and such a design can make the lateral guide wheel 333 roll along the side wall of the cavity 112, so as to adjust the lateral distance of the door body. In this embodiment, the load wheel 313 can be arranged at both ends of the guide wheel connecting rod 315, and the lateral guide wheel 333 can be arranged at the adjacent position of the load wheel 313 at the end, or the lateral guide wheel 333 can be arranged at both ends of the guide wheel connecting rod 315, and the load wheel 313 can be arranged at the adjacent position of the lateral guide wheel 333 at the end. Figure 12C

[0126] In this embodiment, the first guide member or the second guide member is taken as the guide wheel as an example but is not limited thereto, and a sliding block can also be used instead.

[0127] In this embodiment, the two load wheels 313 are rotationally connected at both ends of the guide wheel connecting rod 315 through the guide shafts 402, the load wheels 313 can rotate on the guide shafts 402, the axial direction of the guide shaft 402 and the load wheel 313 is parallel to the ground; the guide wheel connecting rod 315 is rotationally connected with one end of the connecting arm 314, and the connecting point can be the middle part of the guide wheel connecting rod 315; and the fixed connecting end 311 is fixedly connected with the other end of the connecting arm 314. Figures 12A-12C

[0128] ​​In an implementation, the connection between the connecting arm 314 and the guide wheel connecting rod 315 can be a cylinder, and a hole can be formed in the guide wheel connecting rod 315 to be sleeved on the connecting arm 314, and the guide wheel connecting rod 315 rotates around the connecting arm 314.

[0129] The guide wheel connecting rod 315 and the guide shaft 402 can function to fix the load bearing wheels 313 and the lateral guide wheels 333. The guide wheel connecting rod 315 is rotationally connected with the connecting arm 314, and the guide wheel connecting rod 315 can swing around the connecting arm 314, that is, the load bearing wheels 313 at both ends can rotate around the connecting arm 314, so as to support the longitudinal force of the door body and automatically adjust the longitudinal force during the operation of the door body, so that the door body is uniformly stressed and the door body is more stable during operation. The fixed connection end 311 supports the entire sliding connecting piece 310.

[0130] The two lateral guide wheels 333 can form a group, and there are two groups in total. The two lateral guide wheels 333 in the same group are connected through the connecting shaft 405, and the two lateral guide wheels 333 are respectively installed at both ends of the connecting shaft 405, and the connecting shaft 405 is installed on the guide wheel connecting rod 315. The guide wheel connecting rod 315 can be provided with hollow positions, and the two hollow positions are respectively located on both sides of the middle part of the guide wheel connecting rod 315. The connecting shafts 405 of the two groups of lateral guide wheels 333 are respectively installed in the hollow positions of the guide wheel connecting rod 315. In this embodiment, when the guide wheel connecting rod 315 is kept horizontal, the axial direction of the lateral guide wheel 333 and the connecting shaft 405 is perpendicular to the ground, and the radial direction is parallel to the ground. The two ends of the guide wheel connecting rod 315 are respectively provided with a load bearing wheel 313, and the lateral guide wheel 333 is arranged at the adjacent position of the load bearing wheels 313 at the left and right ends.

[0131] In this embodiment, the lateral guide wheel 333 is arranged to have a lateral guiding effect on the door body, so that the distance between the door bodies during operation is uniform, and the distance between the door bodies is kept as constant as possible during operation to prevent shaking and jamming of the door body during operation.

[0132] The sliding connection end 312 is connected with one door body, and the fixed connection end 311 is connected with another adjacent door body. The fixed connection end 311 is fixedly connected with the bottom of the first door body 100, for example, is fixedly connected with the door body sliding rod 180 at the bottom of the first door body 100. The door body sliding rod 180 can be provided with an open cavity 112, and the fixed connection end 311 can be fixedly connected in the cavity 112 of the door body sliding rod 180, so as to realize the fixed connection with the first door body. The load wheels 313 and the lateral guide wheels 333 are slidingly connected with the bottom of the second door body 200, for example, are slidingly connected with the door body sliding rod 181 at the bottom of the second door body 200. The door body sliding rod 181 at the bottom of the second door body 200 can be provided with an open cavity 411, two load wheels 313 extend into and are locked in the cavity 411 of the door body sliding rod 181 in the second door body 200 to slide, and two groups of four lateral guide wheels 333 also extend into and are locked in the cavity 411 of the door body sliding rod 181 in the second door body 200 to slide, so as to realize the sliding connection with the second door body 200 and simultaneously support the second door body 200 in the longitudinal direction, so that the first door body 100 and the second door body 200 are connected with each other and can slide relative to each other. The cavity 411 can include a top wall, a bottom wall and two side walls, the two load wheels 313 can be limited between the two side walls and roll between the top wall and the bottom wall, and the four lateral guide wheels 333 can roll along the side walls of the cavity 411 and have a lateral guiding effect on the second door body 200, so as to reduce friction and noise.

[0133] For example, the two load wheels 313 and the four lateral guide wheels 333 are limited in the cavity 411 of the second door body 200 and can roll along the cavity 411 in the running direction of the second door body 200, and the two load wheels 313 support the second door body 200 in the longitudinal direction. The diameters of the two load wheels 313 are greater than the length of the connecting shaft 405, so that the four lateral guide wheels 333 do not contact the top wall or the bottom wall of the cavity 411 but roll along the side walls of the cavity 411 and are limited by the side walls of the cavity 411 to have a lateral guiding effect. The diameters of the lateral guide wheels 333 are greater than the width of the guide wheel connecting rod 315, so that the load wheels 313 do not contact the side walls of the cavity 411. The two load wheels 313 support the second door body 200 in the longitudinal direction, and the two groups of four lateral guide wheels 333 guide the second door body 200, so as to reduce friction and noise and make the relative sliding between the first door body 100 and the second door body 200 more stable.

[0134] It should be noted that the fixed connection end 311 can also be fixedly connected with the bottom of the second door body 200, and the load wheels 313 and the lateral guide wheels 333 can be slidingly connected with the bottom of the first door body 100. It should also be noted that the sliding connection end 312 and the fixed connection end 311 can also be connected with the top of the door body.

[0135] This embodiment achieves concealed installation of the sliding connector 309 by installing the fixed connecting end 311, the load-bearing wheel 313, and the side guide wheel 333 into the cavity 411 at the bottom of a door body. This effectively utilizes space and makes the product's appearance simpler and more aesthetically pleasing. It should be noted that concealed installation can also be achieved by installing only the sliding connecting end 312 or only the fixed connecting end 311 into the cavity at the bottom of the door body. Alternatively, concealed installation can be achieved by installing only the sliding connecting end 312 or only the fixed connecting end 311 into the cavity at the top of the door body, or by installing both the sliding connecting end 312 and the fixed connecting end 311 into the cavities at the top of two adjacent door bodies.

[0136] Figure 13 Show Figure 12A A schematic diagram showing the clockwise rotation of the sliding connection end of the sliding connector in the diagram. Figure 14 Show Figure 12A A schematic diagram of the sliding connection end of the sliding connector rotating counterclockwise.

[0137] Please see Figure 13-14 When the second door 200 is in operation, the longitudinal force on the second door 200 will change, and the longitudinal force on the sliding connection end 312 connected to the bottom of the second door 200 will also change. Since the guide wheel connecting rod 315 of the sliding connection end 312 is rotatably connected to the connecting arm 314, the guide wheel connecting rod 315 can swing around the connecting arm 314, so that the sliding connection end 312 can rotate clockwise or counterclockwise, automatically adjusting the longitudinal force on the second door 200, making the longitudinal force on the door more uniform and the operation more stable.

[0138] See Figure 13 Because the right end bearing wheel 313 is under greater force, the bearing wheels 313 at both ends change from being horizontal and parallel to rotating clockwise around the connecting arm 314 and then rotating clockwise around the connecting arm 314 and then rotating upward, thereby automatically adjusting the longitudinal force on the door body to make the force even.

[0139] See Figure 14 Because the left end load-bearing wheel 313 is under greater force, the load-bearing wheels 313 at both ends change from being horizontal and parallel to rotating counterclockwise around the connecting arm 314 and moving downwards longitudinally, while the right end load-bearing wheel 313 rotates counterclockwise around the connecting arm 314 and moving upwards longitudinally, thereby automatically adjusting the longitudinal force on the door body to make the force even.

[0140] In one embodiment, when the load-bearing wheels 313 at both ends of the guide wheel connecting rod 315 change the longitudinal force on the second door body 200, since the guide wheel connecting rod 315 is rotatably connected to the connecting arm 314, the middle part of the guide wheel connecting rod 315 is rotatably connected to the connecting arm 314, so that the guide wheel connecting rod 315 can swing around the connecting arm 314, thereby causing the two load-bearing wheels 313 at both ends of the guide wheel connecting rod 315 to also rotate longitudinally around the connecting arm 314 and keep sliding contact with the top or bottom wall of the cavity 411, thereby automatically adjusting the longitudinal force on the door body, making the longitudinal force on the door body uniform, and making the door body more stable during operation.

[0141] Figure 15 Show Figure 10 A front view of an optional structure of the sliding connector 319 in the middle. Figure 16 Show Figure 15 Top view of the sliding connector in the middle. Figure 17 Show Figure 15 A three-dimensional structural diagram of the sliding connector is shown. It is understood that the sliding connector 320 may adopt the same or different structure as the sliding connector 319.

[0142] See Figures 15 to 17 The sliding connector 319 includes a sliding connecting end 322 and a fixed connecting end 321. The sliding connecting end 322 and the fixed connecting end 321 are located at opposite ends of the connecting arm 324 and connected by the horizontally arranged connecting arm 324. The sliding connecting end 322 is equipped with a guide wheel 323 for adjusting the lateral force on the door body. The axial direction of the guide wheel 323 is perpendicular to the horizontal extension direction of the connecting arm 324; the radial plane of the guide wheel 323 is perpendicular to the longitudinal connecting surface of the fixed connecting end 321 connecting to the connecting arm 324. The fixed connecting end 321 and the sliding connecting end 322 are on approximately horizontal planes, thus enabling the sliding connector 319 to both guide and connect the two door bodies. The fixed connecting end 321 can also be called a guide wheel seat. The sliding connecting end 322, the fixed connecting end 321, and the connecting arm 324 can be configured as separate parts or as a single unit.

[0143] In an embodiment, the fixed connection end 321 can be a symmetrical mold opening design. With the transverse movement direction of the door body as the reference, the fixed connection end 321 is installed on the door body, and the fixed connection end 321 is a left-right symmetrical structure in the left and right directions along the transverse direction. By setting the fixed connection end 321 as a symmetrical structure, the sliding connector 319 provided in the embodiment can be installed on the door body without being limited by the left-right fixing direction or the front-rear fixing direction. That is, in one installation mode, the fixed connection end 321 is connected with the first door body 100 in the multi-door body structure, and the sliding connection end 322 is connected with the adjacent second door body 200 in the multi-door body structure. In another installation mode, the fixed connection end 321 is connected with the second door body 200 in the multi-door body structure, and the sliding connection end 322 is connected with the adjacent first door body 100 in the multi-door body structure. The two installation modes can be arbitrarily exchanged and are not limited by the left-right fixing direction of the door body installation. In addition, in different embodiments, when the fixed connection end 321 is connected with the door body, it can be installed at the front end of the door body or at the rear end of the door body. When the sliding connection end 322 is connected with the door body, it can be installed at the front end of the door body or at the rear end of the door body, and is not limited by the front-rear fixing direction of the door body. Therefore, by setting the fixed connection end 321 as a symmetrical structure of the symmetrical mold opening design, the on-site installation is not limited by the left-right fixing direction or the front-rear fixing direction, and the installation is more convenient. In addition, such a design can also reduce the material of the sliding connector 319, making it easier to manufacture, reducing the manufacturing cost and improving the manufacturing efficiency.

[0144] Referring to Figure 15 and Figure 17 In an embodiment, the fixed connection end 321 can be provided with a wiring cavity 3211 inside. The wiring cavity 3211 inside the fixed connection end 321 is used for laying wires, so that a wire cover does not need to be provided. Laying the door body wires in the wiring cavity 3211 inside the fixed connection end 321 can play a role in hidden wiring, effectively utilize the space, and also make the appearance of the sliding connector 319 more simple and beautiful, which is also beneficial to improve the service life of the door body wires and avoid wire damage.

[0145] In an embodiment, the sliding connection end 322 can be provided with a guide wheel connecting rod 325 rotatably connected to the connecting arm 324, and guide wheels 323 respectively arranged at both ends of the guide wheel connecting rod 325, wherein the guide wheel connecting rod 325 rotates around the connecting arm 324 in the horizontal direction. The guide wheels 323 are rotatably installed on the guide wheel connecting rod 325. The guide wheels 323 at least include two, respectively located at both ends of the guide wheel connecting rod 325. Among them, the guide wheel connecting rod 325 is a guide connecting rod, and the guide wheels 323 are guides. The guide connecting rod can also be a sliding block connecting rod, and the guide can also be a sliding block.

[0146] In an embodiment, the guide wheel 323 can be rotatably connected with the guide wheel connecting rod 325, both ends of the guide wheel connecting rod 325 are fixedly arranged with the connecting shaft 3231 in the longitudinal direction, and the guide wheel 323 is rotatably installed on the connecting shaft 3231, so that the guide wheel 323 can rotate laterally. Wherein when the guide wheel connecting rod 325 remains horizontal, the axial direction of the guide wheel 323 and the connecting shaft 3231 is perpendicular to the ground, and the radial direction is parallel to the ground. Taking the guide wheel 323 as the guide wheel and the connecting shaft 3231 as the guide wheel shaft as an example, the guide wheel is rotatably connected with the guide wheel connecting rod 325, both ends of the guide wheel connecting rod 325 are fixedly arranged with the guide wheel shaft in the longitudinal direction, and the guide wheel is rotatably installed on the guide wheel shaft, so that the guide wheel can rotate laterally. It should be noted that the number of guide wheels 323 can be set to multiple, and the present disclosure does not limit the number, and accordingly, the number of connecting shafts 3231 can also be set to multiple. The plurality of guide wheels 323 can be connected together through the guide wheel connecting rod 325, and the plurality of guide wheels 323 are arranged at intervals from each other, so that the rotation of the plurality of guide wheels 323 does not affect each other, and the plurality of guide wheels 323 can cooperate with each other to make the lateral force of the door body more uniform, and in the multi-door structure, the distance between the door bodies can be kept constant, and the operation of the door bodies is more stable.

[0147] Referring to Figures 15-17 In an embodiment, the connecting arm 324 can include a connecting portion 3141 and a supporting portion 3142, the connecting portion 3141 can connect the fixed connecting end 321 and the supporting portion 3142 together, and the supporting portion 3142 is used for supporting the sliding connecting end 322, and a supporting shaft 3143 can be arranged on the supporting portion 3142 and rotatably connected with the guide wheel connecting rod 325. The supporting shaft 3143 can be arranged at the middle position of the supporting portion 3142. In an embodiment, the part where the supporting shaft 3143 is connected with the guide wheel connecting rod 325 can be a cylinder, that is, the supporting shaft 3143 can be in the shape of a cylinder, a hole can be formed in the guide wheel connecting rod 325, and the guide wheel connecting rod 325 is sleeved on the supporting shaft 3143 and rotates horizontally around the supporting shaft 3143. Since the guide wheel connecting rod 325 can rotate laterally around the supporting shaft 3143, the guide wheel 323 on the guide wheel connecting rod 325 can automatically adjust the lateral force of the door body, so that the door body is uniformly stressed, and the relative movement between the door bodies is more stable.

[0148] In this embodiment, the connecting arm 324 can extend from the fixed connecting end 321 to the support portion 3142 and form an integral with the support portion 3142. The support portion 3142 is arranged on the side where the sliding connecting end 322 is located to support the sliding connecting end 322. The guide wheel connecting rod 325 is located above the support portion 3142 and can be rotatably connected to the support portion 3142 through the longitudinally arranged support shaft 3143. A recessed portion can be arranged on the upper surface of the support portion 3142, and the support shaft 3143 can be fixedly arranged at the central portion of the recessed portion, so that the guide wheel connecting rod 325 can be partially accommodated in the recessed portion and a gap is left between the guide wheel connecting rod 325 and the recessed portion. In this way, the guide wheel connecting rod 325 and the guide wheel can be protected to a certain extent through the recessed portion, so that the guide wheel connecting rod 325 and the guide wheel are more stable during movement. It should be noted that the side of the support portion 3142 can also be provided with a cavity for hidden wiring. The hollow structure left with a gap between the guide wheel connecting rod 325 and the support portion 3142 and the structure provided with a cavity on the side of the support portion 3142 can better perform hidden wiring. It should be noted that the support portion 3142 arranged on the connecting arm 324 can better support the sliding connecting end 322, and the support shaft 3143 arranged on the support portion 3142 is rotatably connected with the guide wheel connecting rod 325, so that the guide wheel connecting rod 325 can rotate horizontally around the support shaft 3143, and the lateral force of the door body can be better automatically adjusted to make the force more uniform.

[0149] It should be noted that the guide wheel 323 in this embodiment can be replaced by a sliding block. By arranging the guide wheel or the sliding block, the frictional force when contacting the door body can be reduced, and the stability of the door body during movement can be improved.

[0150] Referring to Figure 9 and Figure 9B together, the fixed connecting end 321 is connected with the first door body 100, and the sliding connecting end 322 is connected with the second door body 200. The sliding connecting end 322 can be slidably connected with the top of the second door body 200, for example, with the sliding rod 210 at the top of the second door body 200. The sliding rod 210 at the top of the second door body 200 can be provided with an open cavity 412, and the guide wheel 323 extends into and is locked in the cavity 412 of the sliding rod of the second door body 200 to achieve sliding connection with the second door body 200, so that the first door body 100 and the second door body 200 are connected with each other and can slide relative to each other. The cavity 412 can include two side walls 4121 and 4122, and the guide wheel 323 can roll along the side walls 4121 and 4122 of the cavity 412 to have a lateral guiding effect on the second door body 200, reduce the frictional force when the guide wheel 323 contacts the door body, and improve the stability of the door body during movement.

[0151] For example, two guide wheels 323 are arranged at the sliding connection end 322, and the two guide wheels 323 are connected by a guide wheel connecting rod 325 and are respectively located at two ends of the guide wheel connecting rod 325. The middle part of the guide wheel connecting rod 325 is rotationally connected to the connecting arm 324, so that the guide wheel connecting rod 325 can rotate in the lateral direction of the connecting arm 324, and then the two guide wheels 323 at the two ends of the guide wheel connecting rod 325 are always in sliding contact with the side wall 4121 or 4122 of the cavity 412, that is, the guide wheel 323 is limited between the two side walls 4121 and 4122 and rolls with one of the side walls. Therefore, when the second door body 200 is operated, the lateral force of the second door body 200 can be automatically adjusted, so that the sliding support of the first door body 100 to the second door body 200 in the lateral direction is more stable, and the relative movement between the door bodies is more stable and is not easy to be stuck.

[0152] In this embodiment, the cavity 412 can be opened along the length direction of the door body sliding rod 210, and the structure of the cavity 412 is matched with the shape of the sliding connection end 322. When the sliding connection piece 319 is installed, the fixed connection end 321 can be first fixedly connected with the first door body 100, and then the guide wheels 323 of the sliding connection end 322 are aligned with the opening of the cavity 412 of the second door body 200 and are slowly clamped in. After clamping, the sliding connection end 322 is accommodated in the cavity 412, the guide wheels 323 abut against the side walls 4121 and 4122 of the cavity 412, and the connecting arm 324 extends outward from the opening of the cavity 412 and is connected to the fixed connection end 321 on the first door body 100. Such a structure can make the sliding connection end 322 slidingly locked in the cavity 412, realize the sliding connection of the first door body 100 and the second door body 200, and also realize the hidden installation of the sliding connection end 322 in the cavity at the top of the door body.

[0153] It should be noted that the connection positions of the fixed connection end 321 and the sliding connection end 322 with the door body can also be the bottom of the door body. For example, the sliding connection end 322 is connected with the bottom of a door body, and the fixed connection end 321 is connected with the bottom of another adjacent door body. The bottom of the door body can also be provided with a cavity capable of accommodating the fixed connection end 321 and the sliding connection end 322.

[0154] It should be noted that the above-mentioned sliding connection end 322 is installed in the top cavity of a door body to realize hidden installation, but it is not limited to this. According to the needs, the fixed connection end 321 can also be installed in the top cavity of a door body to realize hidden installation. The sliding connection end 322 and the fixed connection end 321 can be simultaneously hidden. Alternatively, only the fixed connection end 321 is installed in the top cavity of a door body. In addition, only the sliding connection end 322 can be installed in the bottom cavity of a door body to realize hidden installation, or only the fixed connection end 321 is installed in the bottom cavity of a door body, or the sliding connection end 200 is installed in the bottom cavity of a door body, and the fixed connection end 321 is installed in the bottom cavity of an adjacent door body, so that the sliding connection end 322 and the fixed connection end 100 can be simultaneously hidden in the bottom of the door body.

[0155] Figure 18 A schematic view showing the sliding connection end of the sliding connector in Figure 15 clockwise rotation, Figure 19 A schematic view showing the sliding connection end of the sliding connector in Figure 15 counterclockwise rotation.

[0156] Referring to Figure 18 and Figure 19 , since the guide wheels 323 can be provided in multiple, the multiple guide wheels 323 can be rotatably connected with the guide wheel connecting rod 325 through the connecting shaft 3231, for example, two guide wheels 323 are respectively located at both ends of the guide wheel connecting rod 325 and are rotatably connected with the guide wheel connecting rod 325, and the guide wheel connecting rod 325 can be rotatably connected with the fixed connection end 321 through the support shaft 3143 on the connecting arm 324. Therefore, during the opening or closing movement of the door body, the guide wheel connecting rod 325 can rotate clockwise or counterclockwise in the lateral direction of the connecting arm 324, thereby making the two guide wheels 323 located at both ends of the guide wheel connecting rod 325 always in sliding contact with the side walls 4121 and 4122 of the cavity 412. This can not only reduce the friction of the sliding connection end 322 in the cavity 412 at the top of the door body, but also dynamically adjust the lateral force of the door body, making the movement of the door body more stable.

[0157] Figure 20 A cross-sectional view of the first door body of the translation door shown in Figure 1 is shown, Figure 21 is a perspective view of a ring-shaped mechanism of a translation door according to Figure 1 , Figure 21A is a partial enlarged view of A in Figure 21 , Figure 21B is a partial enlarged view of B in Figure 21 , Figure 21C is a partial enlarged view of C in Figure 21A . Referring to Figure 20 and Figure 21 The first door body 100 drives the second door body 200 through the ring mechanism H. The ring mechanism H includes a transmission belt 150, a first pulley 130 and a second pulley 120 arranged between the sliding support 510 and the sliding support 520. The sliding support 510 and the sliding support 520 are fixed to the ground, the first pulley 130 and the second pulley 120 are fixed to the transverse ends of the first door body 100, the transmission belt 150 is arranged around the first pulley 130 and the second pulley 120, the first pulley 130 and the second pulley 120 are stationary relative to the first door body 100, and are moving relative to the ground when the first door body 100 moves, that is, the transmission belt 150 is moving relative to the sliding support 510 and the sliding support 520. One end of the door body connecting plate 160 is fixed on the transmission belt 150, and the other end of the door body connecting plate 160 is fixedly connected with the second door body 200. In this embodiment, the other end of the door body connecting plate 160 is fixed to the rear end of the second door body 160. When the motor 400 rotates to drive the first door body 100 to move transversely, the sliding support 510 and the sliding support 520 are fixed to the ground, the first pulley 130 and the second pulley 120 drive the transmission belt 150 to move with the door body, so that the door body connecting plate 160 drives the second door body 200 to move transversely. In an implementation, one end of the transmission belt 150 can be fixedly arranged around the sliding support 510, and the other end can be fixedly arranged around the sliding support 520. It should be noted that, as an alternative, the two ends of the transmission belt 150 can also be fixedly arranged around other positions fixed relative to the ground, for example, two vertical columns can be fixed beside the sliding support 510 and the sliding support 520, and the two ends of the transmission belt 150 are no longer fixed to the sliding support 510 and the sliding support 520, but are fixed to the vertical columns, which can also realize the function of the ring mechanism H.

[0158] With reference to Figure 21 and Figure 21C The first pulley 130 and the second pulley 120 are elastically connected with the first door body 100 through the tensioning device 170 respectively. In this embodiment, the first pulley 130 and the second pulley 120 are fixedly installed in the door body sliding rod 110 of the first door body 100 through the spring tensioning device 170 at the front and rear ends respectively. Figure 21CThe structure of the spring tensioning device 170 is described by taking one end where the first pulley 130 is located as an example. The spring tensioning device 170 includes a screw rod 171, a nut 172, a spring 173, and a pulley connecting plate 174. The first pulley 130 can move forward and backward relative to the pulley connecting plate 174. The first pulley 130 and the pulley connecting plate 174 are connected through the screw rod 171. One end of the screw rod 171 is fixed to the first pulley 130 through a connecting piece. After the screw rod 171 penetrates through the pulley connecting plate 174, the part extending out is sleeved with the spring 173, and the nut 172 is screwed. One end of the spring 173 elastically abuts on the nut 172, and the other end elastically abuts on the pulley connecting plate 174. By screwing the nut 172, the first pulley 130 is driven to stretch in the direction of approaching the pulley connecting plate 174, so that the tensioning of the transmission belt 150 can be realized. At the same time, after the nut 172 is screwed, the nut 172 will compress the spring 173 on the pulley connecting plate 174, so that the spring 173 generates a rebound force consistent with the stretching direction of the first pulley 130. Under the action of the rebound force, even if the transmission belt 150 is stretched due to deformation after long-term use, it will also be automatically tensioned by the spring tensioning device 170, so that the transmission belt 150 is always in a tensioning state, which is beneficial to reduce noise and effectively improve the running stability of the ring mechanism H. Moreover, the spring tensioning device 170 is hiddenly arranged in the cavity 111 together with the ring mechanism H, which ensures the stability of the sliding door operation, reduces the maintenance frequency and maintenance cost in the later period, is not only durable, but also further improves the appearance effect of the sliding door.

[0159] Figure 22A is a top view structural schematic diagram of a sliding door according to an exemplary embodiment of the present disclosure in an open door state; Figure 22B is Figure 22A a state schematic diagram of a corresponding ring mechanism; Figure 22C is a top view structural schematic diagram of a sliding door according to an exemplary embodiment of the present disclosure in a closed door state; Figure 22D is Figure 22C a state schematic diagram of a corresponding ring mechanism. Refer to Figures 22A to 22DIn the open door state, the first door body 100 and the second door body 200 mostly overlap, when the motor 400 drives the first door body 100 to move, the first door body 100 drives the connected second door body 200 to slide forward relative to the first door body 100 through the ring mechanism H and the door body connecting piece 160, and the speed of the second door body 200 is twice the speed of the first door body 100, the overlapping part of the first door body 100 and the second door body 200 gradually becomes smaller, when the first door body 100 and the second door body 200 run to the closed door state, the overlapping part of the first door body 100 and the second door body 200 becomes the smallest, at this time, the closed door width is the largest. In this way, the first door body 100 and the second door body 200 can be linked through the ring mechanism H, when the door is opened, the two door bodies basically overlap each other, which can reduce the door body retreat space; when the door is closed, the overlapping part of the two door bodies is the smallest, which can increase the closed door width.

[0160] Continuing to refer to Figure 20 , Figure 21 and Figure 21B , in the embodiment, the sliding connection ends of the sliding connecting pieces and the sliding support pieces 530 and 540 are accommodated in the corresponding cavities of the door body, the motor 400 is accommodated in the rack, and the sliding support pieces 510 and 520, the first pulley 130, the second pulley 120 and the transmission belt 150 are accommodated in the cavity 111 at the bottom of the first door body 100. Therefore, in the embodiment, the motor, at least two pairs of sliding connecting piece groups, the sliding support pieces 510 and 520, the sliding support pieces 530 and 540, the first pulley 130, the second pulley 120 and the transmission belt are all accommodated in the translation door, which effectively improves the appearance effect of the translation door.

[0161] Referring to Figure 10 and Figure 11 , since the second door body 200 is suspendedly installed on the first door body 100, when in the closed door state, the first door body 100 and the second door body 200 are completely unfolded, the supporting force of the first door body 100 on the second door body 200 decreases, the front end of the second door body 200 will sag due to its own gravity, causing the second door body 200 to be warped towards the rear end, thereby generating longitudinal deformation. In the embodiment, along the closing direction, the sliding connecting piece 309 is arranged at the front end of the second door body 200, and the sliding connecting piece 310 is arranged at the rear end of the second door body 200. The fixed connection end 311 of the sliding connecting piece 309 is fixedly connected to the first door body 100, the sliding connection end 312 of the sliding connecting piece 309 is slidingly connected to the second door body 200, the sliding connection end 312 of the sliding connecting piece 310 is slidingly connected to the first door body 100, and the fixed connection end 311 of the sliding connecting piece 310 is fixedly connected to the second door body 200, and as Figure 23A and Figure 23BAs shown, the longitudinal center of the sliding connection end 312 of the sliding connection piece 309 is aligned with the longitudinal center of the connecting arm 314, and the longitudinal center of the sliding connection end 312 of the sliding connection piece 309 is higher than the longitudinal center of the fixed connection end 311 of the sliding connection piece 309. The longitudinal center of the sliding connection end 312 of the sliding connection piece 310 is aligned with the longitudinal center of the connecting arm 314, and the longitudinal center of the sliding connection end 312 of the sliding connection piece 310 is higher than the longitudinal center of the fixed connection end 311 of the sliding connection piece 310. There is a distance D (see Figure 24 ) between the two. In this way, the longitudinal center of the sliding connection end of the sliding connection piece 309 is higher than the longitudinal center of the fixed connection end of the sliding connection piece 310, so that the translation door is configured to make the front end of the second door body 200 higher than the rear end of the second door body 200 when the second door body 200 is in the open door state, for example, the front end of the support beam or the door body sliding rod 181 at the longitudinal bottom is higher than the rear end, as Figure 24 shown. In this embodiment, the first door body 100 (for example, the support beam or the door body sliding rod 180 at the longitudinal bottom) is substantially parallel to the closing direction of the second door body 200 under the support of the sliding supports 510 and 520. By making the front end of the second door body 200 higher than the rear end of the second door body 200 in the open door state, the upward tilt of the second door body 200 in the closed door state can be reduced, the longitudinal deformation of the second door body 200 due to its own gravity can be compensated, and it is ensured that the support beam at the longitudinal bottom of the second door body 200 is parallel to the closing direction as much as possible when the second door body 200 is in the closed door state, thereby ensuring the stability and service life of the product structure.

[0162] The translation door according to an embodiment of the present disclosure is described in detail above. Some other embodiments of the present disclosure are introduced below.

[0163] In another embodiment, along the closing direction, the sliding connection piece 309 is arranged at the front end of the second door body 200, and the sliding connection piece 310 is arranged at the rear end of the second door body 200. The longitudinal center of the sliding connection end 312 of the sliding connection pieces 309 and 310 is aligned with the longitudinal center of the connecting arm 314. The sliding connection end 312 of the sliding connection piece 309 is connected to the first door body 100, the fixed connection end 311 of the sliding connection piece 309 is fixedly connected to the second door body 200, the fixed connection end 311 of the sliding connection piece 310 is fixedly connected to the first door body 100, and the sliding connection end 312 of the sliding connection piece 310 is connected to the second door body 200, and as Figure 25A and 25BAs shown, the longitudinal center of the fixed connection end 311 of the sliding connection piece 309 is higher than the longitudinal center of the sliding connection end 312 of the sliding connection piece 309, and the longitudinal center of the fixed connection end 311 of the sliding connection piece 310 is higher than the longitudinal center of the sliding connection end 312 of the sliding connection piece 310. In this way, the upward tilt of the second door body 200 in the closed state can be reduced, and the longitudinal deformation of the second door body 200 due to its own gravity can be compensated. It can be understood that other types of sliding connection pieces different from the sliding connection pieces 309 and 310 can also be used, and the present disclosure is not limited in this regard.

[0164] In another embodiment, along the closing direction, the sliding connection piece 309 is arranged at the front end of the second door body 200, and the sliding connection piece 310 is arranged at the rear end of the second door body 200. The longitudinal center of the sliding connection end 312 of the sliding connection piece 309 and the sliding connection piece 310 is aligned with the longitudinal center of the connecting arm 314. The fixed connection end 311 of the sliding connection piece 309 and the sliding connection piece 310 is fixedly connected to the first door body 100, and the sliding connection end 312 of the two is slidingly connected to the second door body 200. In addition, the longitudinal center of the sliding connection end 312 of the sliding connection piece 309 is higher than the longitudinal center of the fixed connection end 311 of the sliding connection piece 309, and the longitudinal center of the fixed connection end 311 of the sliding connection piece 310 is higher than the longitudinal center of the sliding connection end 312 of the sliding connection piece 310. In this way, the upward tilt of the second door body 200 in the closed state can be reduced, and the longitudinal deformation of the second door body 200 due to its own gravity can be compensated. It can be understood that other types of sliding connection pieces different from the sliding connection pieces 309 and 310 can also be used, and the present disclosure is not limited in this regard.

[0165] In another embodiment, along the closing direction, the sliding connection piece 309 is arranged at the front end of the second door body 200, and the sliding connection piece 310 is arranged at the rear end of the second door body 200. The longitudinal center of the sliding connection end 312 of the sliding connection piece 309 and the sliding connection piece 310 is aligned with the longitudinal center of the connecting arm 314. The fixed connection end 311 of the sliding connection piece 309 and the sliding connection piece 310 is fixedly connected to the first door body 100, and the sliding connection end 312 of the two is slidingly connected to the second door body 200. In addition, the longitudinal center of the sliding connection end 312 of the sliding connection piece 309 is higher than the longitudinal center of the fixed connection end 311 of the sliding connection piece 309, and the longitudinal center of the fixed connection end 311 of the sliding connection piece 310 is higher than the longitudinal center of the sliding connection end 312 of the sliding connection piece 310. In this way, the upward tilt of the second door body 200 in the closed state can be reduced, and the longitudinal deformation of the second door body 200 due to its own gravity can be compensated. It can be understood that other types of sliding connection pieces different from the sliding connection pieces 309 and 310 can also be used, and the present disclosure is not limited in this regard.

[0166] In other embodiments, the sliding support 510 at the bottom of the first door body 100 can also be implemented in other structures, for example, only load wheels can be provided without guide wheels; the load wheels and / or guide wheels of the sliding support can be single set or multiple sets, if single set, multiple sliding supports should be provided; for another example, the load wheels or guide wheels can be asymmetrically installed at the two ends of the mounting plate 514. In addition, if the sliding support only has single set of load wheels, the middle part of the pulley mounting plate 514 should be fixedly connected to the support base 511; if the sliding support has multiple sets of load wheels and / or guide wheels, the middle part of the pulley mounting plate 514 can be rotatably or fixedly connected to the support base 511. The sliding support 510 and the sliding support 520 can have the same structure, and it can be understood that in other embodiments, the sliding support 510 and the sliding support 520 can have different structures.

[0167] Figures 26 to 28 The structure of another sliding connector according to an embodiment of the present disclosure is shown, which is suitable for being arranged at the longitudinal top of the sliding door, for example, can replace the sliding connector 319 in the previous embodiment but not limited to this. This embodiment is similar to the sliding connector 319 shown in Figure 17 The difference is that a ball 326 can be fixed at the end of the support shaft 3143, the part where the support shaft 3143 is connected with the guide wheel connecting rod 325 can be the ball 326, and a spherical cavity is arranged on the guide wheel connecting rod 325 to accommodate the ball 326, so that the guide wheel connecting rod 325 can rotate more flexibly through the cooperation of the ball 326 and the spherical cavity.

[0194] It is appreciated that in other embodiments, the sliding support can be configured to slidingly support the door body at both sides of the longitudinal top of the first door body 100. The structure of the sliding support can refer to the corresponding structure in the foregoing embodiments or other suitable structures, and will not be described herein again.

[0195] As shown in the foregoing Figure 41 and Figure 42 embodiments, the sliding door of this embodiment further includes a sliding support 520, and the sliding support 520 and the sliding support 510 both support the door body in the longitudinal direction, and are spaced apart in the transverse direction (i.e., the sliding direction of the door body) and integrally assembled via a connecting member 940. In this embodiment, the sliding support 520 can have the same structure as the sliding support 510, and the sliding support 510 and the sliding support 520 can have the structure as shown in the foregoing Figure 5The connecting member 940 is shown in the structure. In this embodiment, the connecting member 940 includes a connecting strip connected between the sliding support 510 and the sliding support 520. In one implementation, the connecting strip can be a channel steel or a steel pipe welded between the sliding support 510 and the sliding support 520. In another implementation, the connecting member 940 includes a connecting plate connecting the bottom plates of the sliding support 510 and the sliding support 520 below the bottom plates. It can be understood that, alternatively, the bottom plates of the sliding support 510 and the sliding support 520 can be provided as one whole piece.

[0196] In this embodiment, the sliding support 510 and the sliding support 520 are transversely spaced and connected as one whole piece by the connecting member 940, the sliding support 510 and the sliding support 530 are longitudinally spaced and assembled as one whole piece with the portal frame 700, the sliding support 510 and the sliding support 520 longitudinally support the door body, and the sliding support 530 laterally supports the door body.

[0197] In this embodiment, the sliding support 510 and the sliding support 520 can be assembled as one whole piece by the connecting member 940, and the portal frame, the sliding support 510 and the sliding support 530, and the door body can be assembled as one whole piece and then packaged and transported. At the installation site of the sliding door, the integrated door body is only needed to be placed at the position where the sliding door is to be installed, and the bottom plate 730 is fixed to the ground by chemical anchors or expansion screws, so that the sliding door can be fixed to the ground as a whole, and thus the process at the installation site is simple, convenient and fast. In addition, the door body is supported by the three sliding supports, and the portal frame only has a single support, which has the advantages of simple and stable structure and low cost.

[0198] It can be understood that the above configuration is also applicable to the case of having only one door body.

[0199] It can be understood that, in some other embodiments, the sliding support 530 and / or the sliding support 540 can be provided to be locked or slidably support the first door body 100 on both sides of the first door body 100 as described above, or to be provided to slidably support the first door body 100 on one side of the first door body 100.

[0200] It can be understood that, in some other embodiments, the sliding support 530 can be provided to support the door body on one side of the door body, and the stand column 650 can be provided on the other side of the door body, and the sliding support 540 can be provided on the stand column 650 to support the door body on the other side of the door body.

[0201] It can be understood that, in some other embodiments, the portal frame can include two portal frames, for example, the stand column 650 in the foregoing can be replaced by a portal frame.

[0202] In another embodiment, as shown in FIG. 8, the sliding support 510 and the sliding support 520 are longitudinally spaced and connected as one whole piece by the connecting member 940, the sliding support 530 is transversely spaced and assembled as one whole piece with the portal frame 700, and the sliding support 510 and the sliding support 520 longitudinally support the door body, and the sliding support 530 laterally supports the door body. Figure 43As shown, a sliding connector is provided below the second door 200 to support the second door 200 longitudinally. The sliding connector can be a door wheel 220 that is slidably supported on the ground and fixedly installed at the bottom of the second door 200. After the door wheel 220 is installed, the door wheel 220 and the sliding connector 310 jointly provide longitudinal support for the second door 200, making the force on the second door 200 more balanced, reducing the load on the first door 100, and thus making the entire sliding door more durable and its operation more stable.

[0203] Understandably, the door wheel 220 is already able to support the second door 200 longitudinally. At this time, the sliding connection between the first door and the second door can be a lateral support, in which case there can be only guide wheels without load-bearing wheels, or it can be a longitudinal support, depending on the specific structure of the connection.

[0204] Figure 44 This diagram shows a partial structural schematic of a sliding door according to another embodiment of the present disclosure; Figure 45 yes Figure 44 A top view of the sliding door in the open position; Figure 46 yes Figure 44 A top view of the sliding door in the closed position. In other embodiments, such as... Figures 44 to 46 As shown, the sliding door in this embodiment also includes a third door body 600 driven by the second door body 200. In this embodiment, a sliding connector 620 is provided at the bottom of the second door body 200 and the third door body 600 in the longitudinal direction, and a sliding connector (not shown) is also provided at the top of the second door body 200 and the third door body 600 in the longitudinal direction. The second door body 200 and the third door body 600 are slidably locked together as one unit through the sliding connectors between them. It can be understood that the structure of the sliding connector 620 at the bottom of the second door body 200 and the second door body 600 can be the same as the structure of the sliding connector 309, and the structure of the sliding connector at the top can be the same as the structure of the sliding connector 319. The bottom sliding connector 620 and the top sliding connector enable the second door body 200 and the third door body 600 to be stably connected at the top and bottom and slide relatively smoothly. Similar to the first door 100 and the second door 200, the second door 200 and the third door 600 can be connected by another annular mechanism. This annular mechanism includes pulley blocks 550 and 560, and a transmission belt 570 disposed between pulley blocks 550 and 560 (see...). Figure 44), pulley 580 and pulley 590. Pulley set 550 and pulley set 560 are fixed to the side of first door body 100 facing second door body, pulley 580 and pulley 590 are fixed to the transverse ends of door body slide rod 181 of second door body 200, transmission belt 570 is wound around pulley 580 and pulley 590, the two ends of transmission belt 570 are fixed to pulley set 550 and pulley set 560 respectively, pulley 580 and pulley 590 are stationary relative to second door body 200, the positions of pulley set 550 and pulley set 560 are fixed relative to first door body 100, and the positions of pulley set 550 and pulley set 560 relative to the ground change with the sliding of first door body 100, that is, transmission belt 570 is in motion relative to pulley set 550 and pulley set 560. Door body connecting plate 630 is fixed on transmission belt 570, one end of door body connecting plate 630 (see Figure 44 ) is fixed on transmission belt 570, and the other end is fixed on the rear end of third door body 600. When first door body 100 slides from Figure 45 to Figure 46 , door body connecting plate 160 between first door body 100 and second door body 200 drives second door body 200 to slide, and the sliding of second door body 200 in turn drives door body connecting plate 630 to slide together, thereby driving third door body 600 to slide, thereby realizing the linkage of the three door bodies. Similarly, when first door body slides in the reverse direction, the three door bodies can also realize linkage. It should be noted that the number of door bodies is not limited by the present disclosure, and the number of door bodies can also be increased according to actual needs. When multiple door bodies are provided, the multiple door bodies are overlapped and extended and retracted, which can further reduce the retracted space of the sliding door and increase the closed width of the sliding door, and the installation site constraint factor is small, and the versatility is strong.
