The automatic umbrella can be a two-fold umbrella, a three-fold umbrella or a four-fold umbrella.

The operation of the automatic umbrella of the present embodiment will be described in detail below.

When the umbrella needs to be opened, the button seat 201 on the umbrella handle 10 is pressed, the button seat 201 presses the door-shaped hook 202 downwards, the door-shaped hook 202 moves downwards, the outer pipe 21 is separated from the door-shaped hook 202, the outer pipe 21 is ejected outwards under the action of the long-strip spring 26, and after the outer pipe 21 is completely unfolded, the middle pipe 22 is driven to further move outwards until the whole middle rod 20 is completely unfolded. At this time, the automatic umbrella is fully opened. Meanwhile, as the outer tube 21 and the middle tube 22 leave the umbrella handle 10, the rocker 205 returns to the unlocking position under the action of the torsion spring 206, and the two top feet 2051 of the rocker 205 on the two sides are positioned above the triangular hook plate 203 to stand by. At the same time, the button holder 201 returns to the original position.

Because one end of the safety rope 103 is connected with the upper nest of the automatic umbrella, the safety rope 103 is necessarily pulled when the upper nest moves away from the umbrella handle 10, the wire wheel 101 is driven to rotate reversely, the safety rope 103 wound on the wire wheel 101 is drawn out until the whole umbrella is completely opened, meanwhile, the reverse rotation of the wire wheel 101 drives the spring 104 to contract and accumulate torsion, and at the moment, the lock bullet 204 is still positioned at the locking position.

When the umbrella is to be folded, the button seat 201 is pressed, and the rocker 205 is in the unlocking position, the button seat 201 can be coupled to the triangular hook plate 203 to unlock the locking bullet 204, and after the control handle 1023 loses the pushing force of the locking bullet 204, the safety catch 102 rotates around the shaft center 1022 under the elastic force of the first spring 105, so that the pawl 1021 is engaged with the ratchet 1012 to prevent the reverse rotation of the reel 101, but the forward rotation of the reel 101 is not influenced.

The umbrella frame can be folded under the condition that the pulling force of the locking bullet 204 is lost, and if the umbrella is completely folded and folded, the middle rod 20 needs to be completely pulled back. During the process of pulling back the outer tube 21 and the middle tube 22, since the safety rope 103 is fixed on the reel 101 and the spring 104 on the reel 101 accumulates enough torque, the spring 104 will drive the reel 101 to rotate forward, tighten the safety rope 103 and wind the reel 101 slowly, at this time, if the hand is released, since the pawl 1021 is engaged with the ratchet 1012, the reverse rotation of the reel 101 is limited, and the outer tube 21 and the middle tube 22 will not pop out again under the elastic force of the strip spring 26, but will remain still. The user can continue to pull back the outer tube 21 and the middle tube 22 little by little until the outer tube 21 is locked by the door hook 202 and the entire umbrella is fully collapsed. Therefore, even if the umbrella is operated by children, the safety risk is avoided, and the use safety of the automatic umbrella is greatly improved.
