[0002] Traditional umbrellas usually can press a button to automatically open the umbrella and ribs, but there is no automatic folding function, which is inconvenient. Therefore, people have invented electric umbrellas that can automatically fold. However, the umbrella surface of existing electric umbrellas remains outside and cannot be put into the tube. The disadvantages are: 1. The ribs and umbrella surface are easily damaged by bumps. 2. In order to store the umbrella surface neatly, it is usually necessary to wrap a belt around the umbrella surface and tie it tightly, which is troublesome to operate. 3. After using it in rainy days, the umbrella surface is wet and dripping, which poses a certain safety hazard. Summary of the invention

[0016] The present invention relates to a fully automatic built-in electric umbrella. Figure 1 — Figure 6 As shown, when in use, the control button is pressed by a finger, and the control button is divided into an umbrella opening button (32) and an umbrella closing button (33), which are connected to a circuit control board, and the circuit control board is used to control the driving motor (30) to rotate forward or reverse, and the output shaft of the driving motor is connected to the winding wheel (29), thereby driving the first pull rope (8) and the second pull rope (9) to be retracted and released;

[0017] When the above umbrella is in the closed state ( Figure 2 ), the sliding column (20) pops up, and the locking hook (18) locks the U-shaped locking tongue (19). At this time, the first sliding component and the second sliding component are locked in position, and the second sliding component cannot move up and down in the second middle rod.

[0018] When the umbrella needs to be opened, the umbrella opening button (32) is pressed with one hand, and the driving motor (30) rotates forward, the winding wheel (29) drives the first pull rope (8) to collect the rope, and the second pull rope (9) to release the rope. At this time, the first movable pulley (6) is subjected to force, driving the first sliding component (16) to move upward along the first sliding groove (34), thereby driving the second middle rod (3) to extend upward. Since the first sliding component and the second sliding component (17) are in a locked state at this time, the umbrella cannot be opened; when the second middle rod is fully extended, the pop-up sliding column (20) supports the limit block (23), and the sliding column is forced to press the locking hook (18) downward. At this time, the locking hook pops up, the first sliding component and the second sliding component are released from the locking position, and the U-shaped lock tongue (19) at the bottom of the second sliding component is released from the locking position and is forced to move upward, thereby driving the lower honeycomb (11) to move upward, and the umbrella opens. At the same time, the locking pin (21) pops out and locks the first locking hole (36).

[0019] When the above umbrella is in the open state ( Figure 1 ), the locking pin (21) locks the first locking hole (36), and at this time, the second middle rod (3) and the first middle rod (2) are locked in position and cannot move up and down.

[0020] When the umbrella needs to be folded, the umbrella folding button (33) is pressed with one hand, at which time the driving motor (30) reverses, the winding wheel (29) drives the second pull rope (9) to retract the rope, and at the same time the first pull rope (8) is released. At this time, the second sliding component (17) is subjected to force, driving the lower honeycomb (11) to move downward, and the umbrella ribs are closed accordingly; since the second middle rod (3) and the first middle rod (2) are in a locked state at this time, the middle rod structure cannot be retracted; when the umbrella ribs are completely closed, the lower end of the second sliding component (17) presses against the locking pin (21), causing the locking pin to retract under the extrusion force, at which time the locking between the second middle rod and the first middle rod is released, and the second middle rod is forced to move downward, thereby driving the umbrella body to retract into the umbrella barrel, and at the same time, the sliding column (20) pops up, and the locking hook (18) is reset to lock the U-shaped locking tongue (19).
