The structure of the first baffle 531 is as follows Figure 3 The structure of the first sleeve 532 is as follows: Figure 4 As shown, the structure of the second blocking piece is consistent with that of the first blocking piece 531 , and the structure of the second sleeve is consistent with that of the first sleeve 532 .

[0028] In this embodiment, the rope-retracting device 10 comprises an inner seat 101 disposed in the umbrella head, a rotating wheel 102, a power member, and a transmission assembly. The rotating wheel 102 is rotatably connected to the inner seat 101, and the axis of the rotating wheel 102 is located in the horizontal direction. The power member is disposed in the inner seat 101 and is connected to the rotating wheel 102 through the transmission assembly. The other end of the first parachute-opening rope 8 and the other end of the first parachute-closing rope 20 are respectively connected to the rotating wheel 102. The power member is specifically a motor ( Figure 1 , Figure 2 The middle number 103 indicates the installation position of the motor), and the motor is a reduction motor. The transmission assembly includes a first bevel gear 104 and a second bevel gear 104. The output shaft of the motor 103 faces upward, the first bevel gear 104 is fixed on the output shaft of the motor, the second bevel gear 104 is coaxially fixedly connected with the rotating wheel 102, and the first bevel gear 104 is meshed with the second bevel gear 104. The rotating wheel 102 specifically includes a first rotating wheel 1021 and a second rotating wheel 1022, which are coaxially fixedly connected. The other end of the first parachute opening rope 8 is connected to the first rotating wheel 1021, and the other end of the first parachute closing rope 20 is connected to the second rotating wheel 1022. The present invention sets the rotating wheel 102 as a two-piece type, which is convenient for adjusting the length of the first parachute opening rope 8 and the first parachute closing rope 20.

[0029] The working principle of the fully automatic opening and closing umbrella of the present invention is as follows:

[0030] When the parachute is opened, the motor is started, and the rotating wheel 102 is driven to rotate in the first direction through the transmission assembly, thereby driving the first parachute opening rope 8 to retract. As the first parachute opening rope 8 is gradually wound around the rotating wheel 102, the middle tube 5 is pulled upward relative to the inner tube 6 by the upward pulling force of one end of the first parachute opening rope 8; as the middle tube 5 moves upward, the distance between the second wheel seat 51 and the third wheel seat 61 increases, and the other end of the second parachute opening rope 9 will pull the outer tube 4 to move upward relative to the middle tube 5 to supplement the change in the distance between the second wheel seat 51 and the third wheel seat 61; as the outer tube 4 moves upward, the distance between the first wheel seat 41 and the second wheel seat 51 increases, and the other end of the lower nest rope 7 will pull the lower nest 3 to move upward relative to the outer tube 4 to supplement the change in the distance between the first wheel seat 41 and the second wheel seat 51. As the lower nest 3 moves upward, the umbrella frame 1 is pushed, and the parachute opening action is finally completed. During the parachute opening process, the first parachute opening rope 8 is in the rope-collecting working state, and the first parachute-collecting rope 20 is in the rope-releasing working state, so as to adapt to the displacement change of the middle tube 5 and the inner tube 6, and also prepare for the parachute-collecting process. Figure 7 shown.

[0031] When folding the umbrella, the motor starts and drives the rotating wheel 102 to rotate in the second direction (the second direction is opposite to the first direction) through the transmission component, thereby driving the first umbrella folding rope 20 to fold. As the first umbrella folding rope 20 is gradually wound around the rotating wheel 102, the fourth wheel seat 63 moves downward. At the same time, the middle tube 5 moves downward relative to the inner tube 6 due to the downward pulling force of one end of the first umbrella folding rope 20; as the fourth wheel seat 63 moves downward, the other end of the second umbrella folding rope 30 will pull the outer tube 4 to move downward relative to the middle tube 5; the umbrella frame 1 is automatically folded by the umbrella folding spring 40, and pushes the lower nest 3 to move downward relative to the outer tube 4; as the outer tube 4 moves downward, the distance between the first wheel seat 41 and the second wheel seat 51 decreases, and the other end of the lower nest rope 7 is pulled downward by the lower nest 3 to supplement the change in the distance. During the process of folding the parachute, the first pull cord 20 is in the working state of folding the parachute, and the first pull cord 8 is in the working state of releasing the parachute, so as to adapt to the displacement change of the middle tube 5 and the inner tube 6, and also prepare for the next parachute opening process. Figure 6 shown.

[0032] The present invention is a fully automatic opening and closing umbrella, which adopts the first umbrella opening pull rope 8, the second umbrella opening pull rope 9, the first umbrella closing pull rope 20, and the second umbrella closing pull rope 30 in conjunction with the rope collection and release device 10 to realize the automatic umbrella opening and closing function of the present invention. Compared with the prior art using the middle tube 5 pull rope, screw rod, nut, push rod and other components of the umbrella opening and closing control mechanism, the present invention is obviously lower in cost, lighter in weight, more conducive to miniaturization, and more reliable in operation.

[0033] The above embodiments are only used to further illustrate a fully automatic opening and closing umbrella of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the technical solution of the present invention.
