door row assembly

100, 300 is fully collapsed, the sides of the

door row assembly

100, 300 do not extend beyond the sides of the longest door row assembly. Compared with the prior art, the stretching position of the door row assemblies in the door opening state is eliminated. Like this, can reduce the occupation of land space of a plurality of door row subassemblies, promote the door opening utilization ratio, save the door opening headroom, increase the current flow of door opening and convenience.

door row assemblies

100 and 300. In other embodiments, the door closing state may be set to have the overlap position (the position of the door closing limit may be changed) as needed.

In this embodiment, the fully closed state means that there is no stretching position between the two adjacent

door row assemblies

100 and 300. In other embodiments, the door opening state may be set to a state with a stretching position (the position of the door opening limit may be changed) as needed.

The

door row assemblies
