[0050] Example 1

[0051] Please refer to Figures 1-10 As shown, this embodiment provides an umbrella rib structure, including a central rod 10, an upper ferrule 11 fixedly disposed at the top of the central rod 10, a lower ferrule 12 sleeved on the central rod 10, and an umbrella handle (not shown in the figure) fixedly disposed at the bottom of the central rod 10. The central rod 10 includes an inner tube 101, a middle tube 102, and an outer tube 103 sleeved together, wherein the middle tube 102 can be a single section or multiple sections; a push rod 1021 is fixedly disposed on the middle tube 102, and a power device for driving the push rod 1021 to perform lifting and lowering movements is disposed inside the umbrella handle (as shown in the figure). (Not shown); A closing umbrella rope 13 is provided between the inner tube 101 and the lower nest 12, which moves the lower nest 12 to close the umbrella via a push rod 1021, or a linked closing umbrella rope 13 is provided between the push rod 1021 and the lower nest 12; One end of the outer tube rope 14 is connected to the inner tube 101, and the other end passes around the first middle tube pulley 1022 provided on the tube plug of the middle tube 102 and is connected to the outer tube 103; One end of the opening umbrella rope 15 is connected to the inner tube 101, and the other end passes around the fixed pulley 111 provided on the upper nest 11 and is connected to the lower nest 12.

[0052] Specifically, the power unit is a motor, and the push rod 1021 is screwed to the output shaft 16 of the power unit through the nut 10212. The output shaft 16 of the power unit is a threaded rod. The nut 10212 cooperates with the threaded rod to convert the rotation of the shaft into linear motion by utilizing the rotational motion of the thread. When the output shaft 16 of the motor rotates, the push rod 1021 will move up and down along the threaded rod, thereby driving the middle tube 102 to move.

[0053] When closing the umbrella, the power unit drives the push rod 1021 to move downwards, thereby causing the middle tube 102 to engage with the adjacent inner tube 101. Simultaneously, the first middle tube pulley 1022 on the tube plug of the middle tube 102 drives the outer tube pull rope 14 to pull the outer tube 103 to engage with the adjacent middle tube 102, thereby realizing the retraction of the middle rod 10. At the same time, the umbrella closing pull rope 13, driven by the push rod 1021, pulls the lower canopy 12 downwards, thereby realizing the closing of the umbrella canopy.

[0054] Similarly, when the umbrella opens, the power unit drives the push rod 1021 to move upward, thereby causing the central tube 102 to move upward. The first central tube pulley 1022 located on the tube plug of the central tube 102 simultaneously drives the outer tube pull rope 14 to pull the outer tube 103, causing the central rod 10 to extend. At the same time, the umbrella opening pull rope 15 is simultaneously driven by the fixed pulley 111 located on the upper nest 11, thereby pulling the lower nest 12 upward, realizing the unfolding of the umbrella canopy.

[0055] Thus, by optimizing the design of the umbrella rib structure, the central rod 10 can be simultaneously contracted or extended when the umbrella canopy is closed or opened, making the opening and closing of the umbrella more convenient and effectively improving the user experience.

[0056] In this embodiment, a movable pulley 121 is provided on the lower nest 12 on the same side as the fixed pulley 111. The other end of the parachute opening pull rope 15 passes through the fixed pulley 111 and the movable pulley 121 in sequence and connects to the fixed pulley 111. In this way, by providing the movable pulley 121 on the lower nest 12, the movement path of the parachute opening pull rope 15 can be further controlled and guided, making the path of the parachute opening pull rope 15 pulling the lower nest 12 more stable, which helps to control the movement of the lower nest 12 more precisely. Moreover, through the cooperation between the movable pulley 121 and the fixed pulley 111, it is easier for the parachute opening pull rope 15 to pull the lower nest 12, thus improving the operational efficiency of the parachute opening operation.

[0057] In this embodiment, an elastic element 17 is provided between the umbrella retractor cord 13 and the lower nest 12. The elastic element 17 can be a spring or an elastic band. Since there are certain differences in the tension of the cords, the elastic element 17 can adaptively adjust the cord tension and compensate for changes in cord length, ensuring that each cord is subjected to uniform force and maintaining overall balance and coordination.

[0060] Specifically, when closing the umbrella, the power unit drives the push rod 1021 to move downward, thereby causing the middle tube 102 to engage with the adjacent inner tube 101. The first middle tube pulley 1022, located on the tube plug of the middle tube 102, simultaneously drives the outer tube pull rope 14 to pull the outer tube 103 to engage with the adjacent middle tube 102, thereby realizing the retraction of the middle rod 10. At the same time, the second middle tube pulley 1023 is simultaneously driven downward by the middle tube 102, thereby driving the umbrella closing pull rope 13 to pull the lower nest 12 downward along the inner tube pulley 1011, the second middle tube pulley 1023, the upper nest pulley 112, and the outer tube pulley 1031, thus realizing the closing of the umbrella canopy.

[0061] Similarly, when the umbrella opens, the power unit drives the push rod 1021 to move upward, thereby causing the central tube 102 to move upward. The first central tube pulley 1022 located on the tube plug of the central tube 102 simultaneously drives the outer tube pull rope 14 to pull the outer tube 103, causing the central rod 10 to extend. At the same time, the umbrella opening pull rope 15 is simultaneously driven by the fixed pulley 111 located on the upper nest 11, thereby pulling the lower nest 12 upward, realizing the unfolding of the umbrella canopy.

[0064] Specifically, when closing the umbrella, the power unit drives the push rod 1021 downward, thereby causing the middle tube 102 to engage with the adjacent inner tube 101. Simultaneously, the first middle tube pulley 1022 on the tube plug of the middle tube 102 drives the outer tube pull rope 14 to pull the outer tube 103 to engage with the adjacent middle tube 102. The first pull rope 131 is also simultaneously driven by the second middle tube 102 on the middle tube 102, further pulling the outer tube 103 downward rapidly to engage with the middle tube 102, thus achieving the retraction of the middle rod 10. At the same time, the second pull rope 132 is simultaneously driven by the outer tube pulley 1031 on the outer tube 103, thereby pulling the lower canopy 12 downward, achieving the closing of the umbrella surface.

[0065] Similarly, when the umbrella opens, the power unit drives the push rod 1021 to move upward, thereby causing the central tube 102 to move upward. The first central tube pulley 1022 located on the tube plug of the central tube 102 simultaneously drives the outer tube pull rope 14 to pull the outer tube 103, causing the central rod 10 to extend. At the same time, the umbrella opening pull rope 15 is simultaneously driven by the fixed pulley 111 located on the upper nest 11, thereby pulling the lower nest 12 upward, realizing the unfolding of the umbrella canopy.

[0068] Specifically, when closing the umbrella, the power unit drives the push rod 1021 to move downward, thereby causing the middle tube 102 to engage with the adjacent inner tube 101. The first middle tube pulley 1022, located on the tube plug of the middle tube 102, simultaneously drives the outer tube pull rope 14 to pull the outer tube 103 to engage with the adjacent middle tube 102, thereby realizing the retraction of the middle rod 10.
