[0020] The present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-3A straight-rib umbrella that can be automatically retracted and unfolded, comprising a middle rod 1 formed by an inner tube 11 and an outer tube 12 that can be slidably sheathed in the axial direction, an umbrella nest 2 sheathed on the inner tube 11, an umbrella rib 3 hinged to the umbrella nest 2, a pulley mechanism arranged in the middle rod 1, a pull line wound around the pulley mechanism and capable of driving the umbrella nest 2 to slide upward, an umbrella handle 4, a button 41 arranged on the umbrella handle 4, an umbrella head, an umbrella cloth, and an umbrella bead 7 for fixing the umbrella cloth, wherein the button 41 comprises an umbrella opening button 411 and an umbrella closing button 412, the umbrella nest 2 comprises an upper umbrella nest 21, a middle umbrella nest 22, and a lower umbrella nest 23, and a pulley for fixing the umbrella cloth is arranged between the upper umbrella nest 21 and the middle umbrella nest 22. The spring 12 for opening the umbrella, the outer sleeve 12 is arranged below the lower umbrella nest 23 and fixedly connected to the lower part of the lower umbrella nest 23, the lower part of the outer sleeve 12 and the upper part of the umbrella handle 4 form a tenon structure 151, the umbrella opening button 411 is arranged at a position corresponding to the tenon structure 151, the lower part of the upper umbrella nest 21 is fixedly connected to a double-layer slide rail sleeve 8, the outer part of the double-layer slide rail sleeve 8 is sleeved with a spring 25 for storing energy for the umbrella closing operation, the lower part of the double-layer slide rail sleeve 8 and the upper part of the middle umbrella nest 22 jointly form a tenon structure 252, and a release block 83 is elastically arranged at the lower part of the double-layer slide rail sleeve 8 corresponding to the tenon structure 252. A traction rope 6 is also arranged in the middle rod 1, and the umbrella closing button 412 is connected to the release block 83 through the traction rope 6. When the umbrella is in the folded state, the spring 124 is in a compressed state due to the restriction of the tenon structure 151 to store energy for the umbrella opening action. When opening the umbrella, by touching the umbrella opening button 411, the stability of the tenon structure 51 is destroyed, resulting in the temporary collapse of the tenon structure 51, and the energy accumulated in the spring 24 is released, so that the umbrella opening action is completed. At the moment of the umbrella opening action, the pulley mechanism in the middle rod 1 and the pull line wound around the pulley mechanism and capable of driving the umbrella nest 2 to slide upward are used to prevent the accumulated force of the spring 24 from being damaged as much as possible during the upward movement. When the middle umbrella nest 22 contacts the spring 25, the lower part of the double-layer slide rail sleeve 8 and the upper part of the middle umbrella nest 22 jointly form the tenon structure 252, completing the fixation of the middle umbrella nest 22 and the double-layer slide rail sleeve 8. The double-layer slide rail sleeve 8 can completely inherit the energy accumulated by the spring 24. The contraction of the double-layer slide rail sleeve 8 and the compression of the spring 25 store the energy required for closing the umbrella. When the umbrella needs to be folded, the release block 83 is controlled by pressing the umbrella closing switch to undergo a certain position change or shape change, thereby destroying the stability of the second latch structure 52, causing the second latch structure 52 to temporarily collapse. The energy stored in the spring 25 is released, allowing the middle umbrella nest 22, the lower umbrella nest 23 and the outer sleeve 12 to smoothly return to the lower part of the umbrella body, and then the outer sleeve 12 is interactively inserted into the umbrella handle 4 by manpower, completing the buckling of the latch structure 51 and accumulating energy for the next umbrella opening operation.

[0022] like Figure 2-5The double-layer slide rail sleeve 8 includes an upper tube 81 and a lower tube 82. The lower tube 82 is slidably arranged inside the upper tube 81. A slot 811 is arranged in the middle and upper part of the inner wall of the upper tube 81, and a diamond-shaped boss 821 is arranged in the upper part of the outer wall of the lower tube 82. After the tenon structure 252 is buckled, the spring 25 accumulates energy for the umbrella closing action by compression. However, after the spring 25 reaches the compression limit or the energy provided by the umbrella opening action is completely transferred to the spring 25, resulting in the maximum value that can be compressed, the spring 25 may reset downward a certain distance due to its own elasticity and not being restricted by the middle umbrella nest 22. This ineffective reset behavior causes a large amount of energy loss, which makes the power provided by the spring 25 insufficient for closing the umbrella, and then leads to poor effect of the automatic umbrella closing action. Therefore, by matching the slot 811 provided in the middle and upper part of the inner wall of the upper tube 81 and the diamond boss 821 provided in the upper part of the outer wall of the lower tube 82, the double-layer slide rail sleeve 8 can be fixed during the compression process, and the spring 25 can be limited by the engagement of the slot 811 and the diamond boss 821 after being compressed to a certain extent, so as to avoid the occurrence of invalid reset. The diamond boss 821 is selected because of its structural characteristics of being large in the middle and small on both sides, which can avoid energy consumption as much as possible when entering and leaving the locked state, so as to ensure the efficient opening and closing of the umbrella. It also includes a power assist device 42, which includes a one-way rotating micro-motor 421 with an automatic reset function and a motor switch 422, the position of the motor switch 422 corresponds to the position of the umbrella closing switch, the traction rope 6 is wound around the micro-motor 421, and a buffer spring 423 is provided between the motor switch 422 and the umbrella closing switch. Since the slot 811 and the diamond boss 821 are provided to limit the invalid reset of the spring 25, if the umbrella closing switch is directly pressed to drive the traction rope 6, the diamond boss 821 may not be separated from the slot 811 due to insufficient torque. Therefore, a micro-motor 421 is provided. Since the purpose of the micro-motor 421 is mainly to help the diamond boss 821 separate from the slot 811, the micro-motor 421 only needs to rotate a small number of circles to move the traction rope 6 a small distance. At the same time, the limitation of its unidirectional rotation ensures that the traction rope 6 can only move along the axial direction, avoiding the occurrence of winding or hinge phenomenon of the traction rope 6 due to the uncertainty of the rotation direction, resulting in damage or collapse of the traction rope 6. By giving the micro-motor 421 an automatic reset function, it can also be effectively ensured that it always has a micro-motion and limited distance pulling function. A through hole 111 is provided on the inner tube 11 at a position corresponding to the middle part of the spring 1 24, and the traction rope 6 passes through the inner tube 11 through the through hole 111 and is connected to the release block 83. By providing the through hole 111 , the traction rope 6 originally arranged in the inner tube 11 is extended to the outside through the through hole 111 and then connected to the release block 83 , which effectively improves the operability of the closing switch or the micro motor 421 on the release block 83 .In order to ensure the connection effect between the middle umbrella nest 22 and the double-layer slide rail sleeve 8, the second latch structure 52 needs to have high stability, which also requires the release block 83 to be able to deform or displace to the maximum extent. The sleeve-type connection mode of the traction rope 6 improves the operability to the highest level, and can better and faster complete the destruction of the second latch structure 52 during the umbrella folding action. The traction rope 6 is a metal steel rope with slight elasticity. The metal steel rope can ensure the upper limit of the force of the traction rope 6, and will not be damaged due to repeated or strong pulling. The slight elasticity it has can also play a buffering role, effectively extending the practical life of the traction rope 6.

[0023] like Figure 1 The ribs 3 include a main rib 31, a supporting rib 1 32, and a supporting rib 2 33. The main rib 31 is hinged to the upper umbrella nest 21. The two ends of the supporting rib 1 32 are respectively hinged to the middle umbrella nest 22 and the middle of the main rib 31. The two ends of the supporting rib 2 33 are respectively hinged to the lower umbrella nest 23 and the rear of the supporting rib 1 32. The main rib 31 is used to open the umbrella cloth. The supporting rib 1 32 hinged to the middle umbrella nest 22 and the main rib 31 can use the tension generated by the main rib 31 when opening to provide auxiliary energy for the middle umbrella nest 22. And the invalid reset of the spring 2 25 can be limited to a certain extent. Similarly, the supporting rib 2 33 hinged to the lower umbrella nest 23 and the rear of the supporting rib 1 32 can drive the lower umbrella nest 23 to move with the middle umbrella nest 22, ensuring that the tension provided by the spring 1 24 can be fully utilized.

[0024] like Figure 1 and 4 , the umbrella opening button 411 and the umbrella closing button 412 are both push-buttons. The push-button can completely seal the internal structure, which can not only prevent the internal structure from being affected by high humidity and causing rust damage or other adverse effects, but also effectively wrap the components to avoid possible damage to the user caused by the movement of the components. At the same time, the material of the umbrella bead 7 is any one of rubber, plastic, and silicone, and the shape of the umbrella bead 7 is a cylinder or a sphere with rounded ends. It can prevent the potential damage to the user caused by overly hard materials or sharp shapes during use, thereby improving the safety of the umbrella bead 7 and the overall aesthetics of the umbrella.

[0025] like Figure 6, the umbrella handle 4 is a "U"-shaped structure, and the free end of the umbrella handle 4 is provided with an adsorption type suction cup 9. Usually, straight-bone umbrellas have the disadvantage of being inconvenient to perform other operations during the umbrella holding process. By converting the straight pole umbrella handle 4 into a two-position "U"-shaped structure, the umbrella handle 4 can meet the needs of users to perform other operations. In the case of a smooth surface around, the umbrella body can also be adsorbed to the smooth surface by the adsorption type suction cup 9 provided at the free end of the umbrella handle 4, truly freeing the hands of the user. After the umbrella is folded, the adsorption type suction cup 9 can be adsorbed to the wall, and the raindrops attached to the umbrella cloth can be quickly removed by gravity, which can also save space.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
