Top rail mounting assembly and blind

A top rail mounting assembly, adapted for a blind, the blind comprising a driving cord and multiple slats connected to the driving cord, and the top rail mounting assembly comprising:

• a power mechanism, comprising multiple power boxes arranged in a housing in a predetermined direction, each power box comprising a box body and an elastic assembly configured inside the box body;
• a driving mechanism, comprising a driving rod and a driving assembly interlinked together, and the driving rod passing through each power box which is interlinked with the driving rod;
• a winding mechanism for winding the driving cord, connected to the driving assembly and interlinked with the power boxes through the driving assembly and the driving rod;
• and
• a positioning mechanism, movably installed inside the housing;
• wherein when the slats are pushed or pulled, the driving cord is configured to wind on or unwind from the winding mechanism to fold or unfold the slats, the winding mechanism is configured to drive the driving assembly to move and drive the driving rod, causing the elastic assembly on the driving rod to be tightened or loosened elastically, and an elastic force released by the elastic assembly is constantly equal to a weight of the slats stacked below;
• wherein the positioning mechanism comprises a guide wheel and a positioning member, one end of the positioning member is provided with a first rotating member, and another end of the positioning member is provided with a second rotating member, the first rotating member is located on one side of the guide wheel, and the second rotating member is located on another side of the guide wheel;
• wherein the driving cord inside the winding mechanism successively passes through the first rotating member, the guiding wheel, and the second rotating member, and then connects to the multiple slats.
