[0028] The linkage door of lower bearing provided in the embodiment sets bearing wheel 4 and linkage structure 5 on the lower side of door leaf 2, makes the area of upper track 1 more simple, is convenient for cleaning and maintenance, and since the upper side of door leaf 2 does not need to provide space for the installation and movement of linkage structure 5, first baffle 11 can be located between two adjacent upper frames 21 to shield the gap between upper track 1 and upper frame 21, avoids light transmission, improves the overall aesthetic degree, and since the gap is shielded, external wind force is difficult to directly act on the area, thereby significantly reducing the abnormal sound generated by wind passing through the gap.

[0029] Specifically, in the embodiment, the linkage door further includes lower track 6, and bearing wheel 4 can slide along lower track 6.

[0030] Specifically, in the embodiment, the door leaf further includes a door panel (not shown in the figure), which is connected between the upper frame 21 and the lower frame 22.

[0031] As Figure 1 and Figure 2As shown, preferably, in the present embodiment, the first baffle 11 is integrally formed on the upper rail 1, and extends along the first direction. Such design not only simplifies the installation steps, avoids additional fixing members and installation costs, but also improves the overall structural integrity and stability. Meanwhile, the first baffle 11 extends along the length direction of the upper rail 1, ensuring that it fully covers the gap between the upper rail 1 and the upper frame 21. Such design not only improves the light-shielding effect, but also enhances the sound insulation performance, making the linkage door perform well in occasions requiring high light-shielding and sound insulation.

[0032] As shown in Figure 1 and Figure 2 , preferably, in the present embodiment, the lower end of the first baffle 11 is lower than the upper end of the upper frame 21. Such arrangement, on the one hand, since the lower end of the first baffle 11 extends below the upper end of the upper frame 21, it more effectively covers the gap between the upper rail 1 and the upper frame 21, preventing light from penetrating from the gap. This not only improves the overall aesthetics, but also ensures that the linkage door can completely block external light in occasions requiring high light-shielding, meeting specific use requirements. On the other hand, the extension of the first baffle 11 in the vertical direction not only increases its coverage area of the gap, but also forms an additional sound insulation barrier. When the external wind is strong, the wind is difficult to directly pass through the gap covered by the first baffle 11, thereby significantly reducing the abnormal noise caused by the wind passing through the gap, improving the sound insulation performance of the door body and the overall use comfort.

In this way, on the one hand, the linkage member 53 is connected between the lower frames 22 of two adjacent door leaves 2, which ensures that when one door leaf 2 moves, other door leaves 2 can be quickly and accurately driven to move synchronously through the linkage structure 5, and such a design not only improves the overall operation efficiency of the linkage door, but also ensures the coordination and consistency of the actions between the door leaves 2, thereby providing a smooth user experience; on the other hand, the pulley 52 is arranged on the lower frame 22 of the driven door leaves, and the belt 51 is arranged around the pulley 52 and the linkage member 53, and such a layout makes the linkage structure 5 more compact, reduces the occupied space, and at the same time, since the belt 51 and the pulley 52 are both located on the lower side of the door leaves 2 and are isolated from the area of the upper track 1, the installation gap problem caused by the installation of the linkage device on the upper side in the traditional design is avoided, and the aesthetic and neatness of the door body are further improved.

In this way, the width of the pulley member 432 is less than the width of the pulley 52, which makes it possible to more flexibly arrange the linkage structure 5 and the load-bearing wheel 4 in a limited space, avoids the space conflict caused by the excessive size of the components, and at the same time, the belt 51 and the pulley member 432 are spaced apart from each other, which reduces the potential interference between them, ensures the smoothness of the belt 51 transmission and the stability of the pulley member 432 sliding, and such a spacing design also helps to reduce the noise and wear caused by friction, prolongs the service life of the components, and in addition, through accurate calculation and design, the relative position and size relationship between the pulley member 432 and the pulley 52 are ensured, which avoids the failure or damage caused by the size mismatch, and improves the overall reliability and stability of the linkage door.

[0039] As shown in Figure 1 , Figure 2 and Figure 3 , more preferably, in the present embodiment, the pulley 52 is connected to the wheel seat 431; in this way, on the one hand, the connection of the pulley 52 and the wheel seat 431 enhances the stability and reliability of the structure, and the wheel seat 431 is designed as a load-bearing component, which usually has high strength and rigidity, connecting the pulley 52 to the wheel seat 431 can ensure that the pulley 52 remains stable during transmission and is not prone to deviation or shaking, thereby improving the accuracy and efficiency of transmission; on the other hand, such a design simplifies the structure and reduces the number of components, in traditional linkage door structures, the pulley 52 and the load wheel 4 are often designed separately, and additional connecting members or supports are needed for fixation, while in the present embodiment, by directly connecting the pulley 52 to the wheel seat 431, these additional components are reduced, not only reducing the manufacturing cost, but also simplifying the installation and maintenance process; on the other hand, the connection of the pulley 52 and the wheel seat 431 also helps to optimize the use of space, as the pulley 52 and the wheel seat 431 are integrated, they can be arranged more flexibly in the limited space of the linkage door structure, avoiding the conflict of space caused by the excessive size of the components.

[0040] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, preferably, in the present embodiment, the lower frame 22 of the driven door leaf comprises a first mounting groove 221, a second mounting groove 222 and a third mounting groove 223 all extending in the first direction, the first mounting groove 221, the second mounting groove 222 and the third mounting groove 223 are arranged in sequence in the second direction, the transmission arm 531 is connected in the first mounting groove 221 and in the third mounting groove 223, and the wheel seat 431 is arranged in the second mounting groove 222. In this way, on the one hand, the first mounting groove 221 and the second mounting groove 222 can both provide sliding connection space for the transmission arm 531, which ensures the stability and reliability of the linkage 53 during movement, reduces abnormal noise and failure caused by loose or deformed parts, and through sliding connection, the linkage 53 can smoothly drive the opening and closing of the door leaf 2, improving the overall performance and user experience of the linkage door; on the other hand, the wheel seat 431 is arranged in the second mounting groove 222 adjacent to the transmission arm 531, such a layout not only optimizes the space utilization, but also ensures the coordinated movement between the load wheel 4 and the linkage 53, and the wheel seat 431 as a load-bearing component generally has high strength and rigidity, can stably support the weight of the door leaf 2, and through the transmission between the pulley 52 and the belt 51, synchronous movement between the door leaves 2 is realized.

[0041] As shown in Figure 1 and Figure 2 As shown, preferably, in the present embodiment, the upper rail 1 is also provided with a second baffle 12, which is located on the side of the upper frame 21 away from the first baffle 11 and can block the gap between the upper rail 1 and the upper frame 21 in the first direction.

[0043] 1) The load wheel 4 and the linkage structure 5 are both arranged on the lower side of the door leaf 2, so that the area of the upper rail 1 is more concise, facilitating cleaning and maintenance;

[0044] 2) Since the upper side of the door leaf 2 does not need to provide space for the installation and movement of the linkage structure 5, the first baffle 11 can be arranged between the two adjacent upper side frames 21 to block the gap between the upper rail 1 and the upper side frame 21, avoiding light penetration and improving the overall aesthetic appearance;

[0045] 3) Since the gap is blocked, external wind is difficult to directly act on this area, thereby significantly reducing the abnormal sound caused by wind passing through the gap;
