During the swinging process, the first upper connecting rod 131 forces the second lower connecting rod 134 to swing upward relative to the base 11 counterclockwise, and the first upper connecting rod 131 and the second upper connecting rod 132 together drive the top seat 12 to swing upward relative to the base 11 clockwise. The fixed end of the connecting rod power telescopic rod 135 is driven by the hinge shaft of the second upper connecting rod 132 and the top seat 12, and follows the second upper connecting rod 132 and the top seat 12 to swing upward relative to the base 11 counterclockwise, and the folding assembly 1 gradually unfolds to the maximum unfolding angle state (i.e., the extreme unfolding position).

[0114] As the folding assembly 1 gradually unfolds to the maximum unfolding angle, the rear part of the tent cloth gradually rises and unfolds. At the same time, the tent top cover 3 drives the movable connecting rod 139 to swing forward, so that the movable U-shaped frame 8 slides along the rotating ring 138, thereby stretching the front part of the tent cloth and completing the unfolding action of the folding tent linkage structure.

[0115] When the folding assembly 1 is folded, the first lower connecting rod 133 and the second lower connecting rod 134 swing downward counterclockwise, and at the same time, the first upper connecting rod 131, the second upper connecting rod 132 and the connecting rod power telescopic rod 135 swing downward clockwise to the extreme folding position, and the top seat 12 swings counterclockwise to cover the second lower connecting rod 134, and the second lower connecting rod 134, the second upper connecting rod 132 and the connecting rod power telescopic rod 135 are folded and folded between the top seat 12 and the base 11.

[0116] As the folding assembly 1 gradually folds to the extreme folding position, the rear part of the tent cloth gradually retracts and folds downward. At the same time, the tent top cover 3 drives the movable connecting rod 139 to swing in the opposite direction, so that the movable U-shaped frame 8 slides along the rotating ring 138, thereby closing the front part of the tent cloth and completing the folding action of the folding tent linkage structure.
