The invention provides a novel trackless electric telescoping door; a first doorframe is connected with the first middle doorframe bottom through a first horizontal intersect linkage in horizontal intersect connection; the first doorframe is connected with the first middle doorframe top through a second horizontal intersect linkage arranged in opposite to the first horizontal intersect linkage and in horizontal intersect connection; the first and second horizontal intersect linkages are connected through a plurality of first vertical rods; a second doorframe is connected with the second middle doorframe bottom through a third horizontal intersect linkage in horizontal intersect connection; the second doorframe is connected with the second middle doorframe top through a fourth horizontal intersect linkage arranged in opposite to the third horizontal intersect linkage and in horizontal intersect connection; the third and fourth horizontal intersect linkages are connected through a plurality of second vertical rods. The intersect linkages receive small forces, and cannot be deformed or broken; the telescoping door is stable in whole body, steady in operation, and can always keep linear operation.
