[0030] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0031] An umbrella provided in an embodiment of the present application may be a rain umbrella, a parasol, etc., but is not limited thereto.

[0032] In one embodiment, see Figure 1 The umbrella comprises an umbrella cloth and an umbrella rib structure 20. The umbrella cloth is arranged on the umbrella rib structure 20, and the umbrella cloth is used for shielding rain and sun, etc., and the umbrella rib structure 20 is used for supporting the umbrella cloth.

[0033] Further, see Figure 1 The rib structure 20 includes a middle rod 21, an upper nest 22, an inner nest 23 and a lower nest 24. The upper nest 22 is fixed to one end of the middle rod 21. The inner nest 23 is movably mounted on the middle rod 21, and the inner nest 23 can move along the axial direction of the middle rod 21 and rotate around the axial direction of the middle rod 21. The lower nest 24 is mounted on at least part of the inner nest 23, for example, the lower nest 24 is mounted on the lower part of the inner nest 23, and the lower nest 24 can move along the axial direction of the middle rod 21. It can be understood that the inner nest 23 and the lower nest 24 are cylindrical sliding structures. By moving the inner nest 23 and the lower nest 24 along the axial direction of the middle rod 21, the umbrella can be driven to be opened and closed. By rotating with the axial direction of the middle rod 21 as the rotation center, the umbrella cloth can be curled, and the umbrella cloth can be automatically rolled up.

[0034] See also Figure 1 and Figure 2The rib structure 20 further includes a main rib 25 and a main support rib 26. One end of the main rib 25 is rotatably connected to the upper nest 22. One end of the main support rib 26 is rotatably connected to the main rib 25, and the other end of the main support rib 26 is rotatably connected to the lower nest 24. The umbrella cloth is laid on the main rib 25, and the main rib 25 is used to support the umbrella cloth.

[0035] Specifically, see Figure 1 The main rib 25 is provided with a main connecting member 251, and the main supporting rib 26 is rotatably connected to the main connecting member 251. Figure 2 The main connecting member 251 is provided with a first ear portion 2511 and a second ear portion 2512 spaced apart, and the first ear portion 2511 and the second ear portion 2512 are both provided with a first connecting hole; one end of the main supporting rib 26 is provided with a first connecting ear, and the first connecting ear is provided with a second connecting hole, and the first connecting ear is provided between the first ear portion 2511 and the second ear portion 2512, and the first connecting hole and the second connecting hole are provided with a first connecting shaft. In this way, the main supporting rib 26 is hinged to the main rib 25.

[0036] See also Figure 1 The rib structure 20 further includes a secondary rib 27 and a secondary support rib 28. One end of the secondary rib 27 is rotatably connected to the upper nest 22. One end of the secondary support rib 28 is slidably and rotatably connected to the secondary rib 27, and the other end of the secondary support rib 28 is rotatably connected to the inner nest 23. The secondary rib 27 is used to roll up the umbrella cloth when the umbrella is folded, so there is no need to manually arrange the umbrella cloth.

[0037] Specifically, see Figure 1 The auxiliary rib 27 is provided with an auxiliary connecting member 271, which can move along the axial direction of the auxiliary rib 27 toward or away from the upper nest 22, and the auxiliary supporting rib 28 is rotatably connected to the auxiliary connecting member 271. For example, see Figure 2 The secondary connecting member 271 is provided with a third ear portion 2711 and a fourth ear portion 2712 spaced apart, and the third ear portion 2711 and the fourth ear portion 2712 are both provided with a third connecting hole; one end of the secondary supporting bone 28 is provided with a second connecting ear, and the second connecting ear is provided with a fourth connecting hole, and the second connecting ear is provided between the third ear portion 2711 and the fourth ear portion 2712, and a second connecting shaft is provided in the third connecting hole and the fourth connecting hole. In this way, the secondary supporting bone 28 and the secondary umbrella bone 27 are connected in a sliding and rotatable manner.

[0038] In one embodiment, see Figure 1 , the length of the main rib 25 is not equal to the length of the auxiliary rib 27. Optionally, the length of the main rib 25 is greater than the length of the auxiliary rib 27. It should be noted that the difference between the lengths of the main rib 25 and the auxiliary rib 27 determines the sliding distance of the inner nest 23 and the lower nest 24.

[0039] Further, see Figure 1 and Figure 2 The auxiliary umbrella rib 27 is provided with a first stopper 2713, and the first stopper 2713 is provided on a side of the auxiliary connecting member 271 away from the upper nest 22. In this way, by providing the first stopper 2713 on the auxiliary umbrella rib 27, the first stopper 2713 can limit the distance that the auxiliary connecting member 271 moves in a direction away from the upper nest 22 during the process of folding the umbrella.

[0040] Further, see Figure 1 and Figure 2 , the inner nest 23 moves along the axial direction of the middle rod 21 in a direction away from the upper nest 22, so that the auxiliary rib 27 has an extreme folded umbrella position. When in the extreme folded umbrella position, the auxiliary connecting member 271 conflicts with the first limiting member 2713, the auxiliary rib 27 is folded, and an escape space is reserved between the main rib 25 and the auxiliary rib 27 for the auxiliary rib 27 to roll up the umbrella cloth.

[0041] When closing your umbrella, refer to Figure 1 and Figure 2 , the external force acts on the lower nest 24, the inner nest 23 and the lower nest 24 move along the axial direction of the middle rod 21 in the direction away from the upper nest 22, so that the main ribs 25 and the auxiliary ribs 27 drive the umbrella cloth to be folded. When the auxiliary connecting member 271 conflicts with the first limiter 2713, the auxiliary ribs 27 reach the limit umbrella folding position, and the auxiliary ribs 27 are in the folded state. Since the length of the main ribs 25 is greater than that of the auxiliary ribs 27, when the auxiliary ribs 27 reach the limit umbrella folding position, the main ribs 25 have not yet reached the folded state, that is, there is an escape space between the main ribs 25 and the auxiliary ribs 27 for the auxiliary ribs 27 to roll up the umbrella cloth.

[0042] In one embodiment, see Figure 1 , Figure 3 and Figure 4 The rib structure 20 further includes a driving assembly 29. The driving assembly 29 includes a pull rope 291, a portion of which is wound around the outer circumference of the inner nest 23, and a portion of the pull rope 291 away from the inner nest 23 is connected to the lower nest 24. When the lower nest 24 moves along the axial direction of the middle rod 21 in a direction away from the upper nest 22, the pull rope 291 is used to drive the inner nest 23 to rotate around the axial direction of the middle rod 21, so as to drive the umbrella cloth to be rolled between the middle rod 21 and the auxiliary rib 27.

[0043] When closing your umbrella, refer to Figure 1 and Figure 4When the auxiliary ribs 27 are in the folded state and the main ribs 25 have not yet reached the folded state, they continue to move along the axial direction of the middle rod 21 in the direction away from the upper nest 22, and the main ribs 25 continue to fold. Since the pull rope 291 is wound around the outer peripheral surface of the inner nest 23, the end of the pull rope 291 away from the inner nest 23 is connected to the lower nest 24. In this way, during the folding process of the main ribs 25, the lower nest 24 pulls the pull rope 291, so that the inner nest 23 rotates around the axial direction of the middle rod 21, and then drives the auxiliary ribs 27 to curl the umbrella cloth, completing the automatic folding of the umbrella cloth. In this way, there is no need to manually arrange the umbrella cloth, and the user will not touch the water during the folding process, which is conducive to improving the user experience.

[0044] When opening the parachute, refer to Figure 1 and Figure 4 , the lower nest 24 is pushed along the axial direction of the middle rod 21 toward the upper nest 22. At the same time, with the help of the elastic potential energy of the curled umbrella cloth of the auxiliary umbrella ribs 27 and the traction of the umbrella cloth, the inner nest 23 rotates around the axial direction of the middle rod 21 to retract the drawstring 291 and wind the drawstring 291 around the inner nest 23. The inner nest 23 returns to the center and continues to push the lower nest 24 along the axial direction of the middle rod 21 toward the upper nest 22 to complete the opening of the umbrella.

[0045] In one embodiment, see Figure 4 and Figure 5 The driving assembly 29 further includes a set 292, which is sleeved on the inner nest 23. The set 292 is provided with a wire groove 2921, and the end of the pull rope 291 away from the inner nest 23 passes through the wire groove 2921 and is connected to the lower nest 24.

[0046] When the main ribs 25 continue to be folded, the lower nest 24 pulls the drawstring 291. Since the drawstring 291 passes through the wire groove 2921 of the sleeve 292, the wire groove 2921 guides the drawstring 291, so that the drawstring 291 moves along a preset direction, so as to better drive the inner nest 23 to rotate around the axial direction of the middle rod 21. In addition, the wire groove 2921 can also play a role of avoiding interference between the drawstring 291 and the sleeve 292.

[0047] Optionally, see Figure 5 , the length direction of the wire groove 2921 is tangent to the radial direction of the middle rod 21. After the pull rope 291 passes through the wire groove 2921, the pull rope 291 in the wire groove 2921 is tangent to the radial direction of the middle rod 21, so when the pull rope 291 is pulled along the axial direction of the middle rod 21 in a direction away from the upper nest 22, the inner nest 23 is subjected to the tangential force and rotates around the axial direction of the middle rod 21, driving the auxiliary ribs 27 to curl the umbrella cloth, and completing the automatic retraction of the umbrella cloth. In this way, it is conducive to the smooth rotation of the inner nest 23 around the axial direction of the middle rod 21.

[0048] It should be noted that the sleeve 292 cannot move along the axial direction of the middle rod 21 relative to the inner nest 23. Figure 4 and Figure 6 The outer circumference of the inner nest 23 is provided with a first limiting portion 231 and a second limiting portion 232, and the first limiting portion 231 and the second limiting portion 232 are spaced apart along the axial direction of the middle rod 21. The sleeve 292 is provided with a first abutting portion 2922 and a second abutting portion 2923, and the first abutting portion 2922 abuts against the first limiting portion 231, and the second abutting portion 2923 abuts against the second limiting portion 232, so as to limit the sleeve 292 from moving relative to the inner nest 23 along the axial direction of the middle rod 21.

[0049] Optionally, see Figure 6 The first limiting portion 231 and the second limiting portion 232 are limiting flanges. Of course, in other embodiments, the first limiting portion 231 and the second limiting portion 232 can also be limiting protrusions.

[0050] Since the first limiting portion 231 and the second limiting portion 232 limit the first abutting portion 2922 and the second abutting portion 2923 respectively, the sleeve 292 can be limited to move along the axial direction of the middle rod 21 relative to the inner nest 23, so as to prevent the sleeve 292 from pulling the pull rope 291 due to the displacement along the axial direction of the middle rod 21 during the process of folding the umbrella, thereby preventing the pull rope 291 from accidentally driving the inner nest 23 to rotate around the axial direction of the middle rod 21. In addition, the sleeve 292 is sleeved on the pull rope 291, and the sleeve 292 can protect the pull rope 291. At the same time, the reasonable arrangement of the sleeve 292 is conducive to simplifying the structure.

[0051] It should be noted that the sleeve 292 cannot rotate relative to the lower nest 24 around the axial direction of the middle rod 21, and the inner nest 23 can rotate relative to the sleeve 292 around the axial direction of the middle rod 21. Figure 6 A guide groove 2924 is provided on one of the outer circumference of the sleeve 292 and the inner circumference of the lower nest 24, and the extension direction of the guide groove 2924 is parallel to the axial direction of the middle rod 21. A guide rail is provided on the other of the outer circumference of the sleeve 292 and the inner circumference of the lower nest 24, and the extension direction of the guide rail is parallel to the axial direction of the middle rod 21. The guide rail is provided in the guide groove 2924 and slidably cooperates with the guide groove 2924.

[0052] With such arrangement, on the one hand, during the process of folding the main ribs 25, that is, during the process of the lower nest 24 driving the pull rope 291 to move along the axial direction of the middle rod 21 in a direction away from the upper nest 22, the sleeve 292 cannot rotate around the axial direction of the middle rod 21 relative to the lower nest 24, so that the pull rope 291 can drive the inner nest 23 to rotate around the axial direction of the middle rod 21 relative to the sleeve 292 under the pulling of the lower nest 24.

[0053] On the other hand, during the process of folding the umbrella, the inner nest 23 drives the guide groove 2924 to move up and down along the direction of the guide rail. The function of this section is to make up for the length difference between the main rib 25 and the auxiliary rib 27. When the auxiliary rib 27 is folded, the main rib 25 can continue to fold the umbrella until it is completely folded. In the process of curling the umbrella cloth, the auxiliary rib 27 will undergo elastic deformation, resulting in the length of the auxiliary rib 27 becoming shorter, and the inner nest 23 moves along the axial direction of the middle rod 21 toward the upper nest 22, which can compensate for the displacement of the inner nest 23. In addition, through the cooperation of the guide rail and the guide groove 2924, the movement of the inner nest 23 is guided, which is conducive to improving the stability of the inner nest 23 moving along the axial direction of the middle rod 21, so as to better fold the umbrella.

[0054] In this embodiment, see Figure 1 and Figure 6 The guide groove 2924 is arranged on the side of the wire groove 2921 away from the upper nest 22 , the guide groove 2924 is connected to the wire groove 2921 , and one end of the pull rope 291 away from the inner nest 23 passes through the wire groove 2921 and is arranged in the guide groove 2924 .

[0055] Understandably, see Figure 1 and Figure 6 The extending direction of the two groove walls of the guide groove 2924 is parallel to the axial direction of the middle rod 21 , and the wire passing groove 2921 is arranged at the groove bottom of the guide groove 2924 close to the side of the upper nest 22 .

[0056] In one embodiment, see Figure 3 and Figure 7 The lower nest 24 is provided with a wire clamping groove 243, and the end of the pull rope 291 away from the inner nest 23 is arranged in the wire clamping groove 243 and is clamped with the wire clamping groove 243. During installation, the end of the pull rope 291 away from the inner nest 23 is clamped into the wire clamping groove 243, and the groove wall of the wire clamping groove 243 clamps the pull rope 291, so that the end of the pull rope 291 away from the inner nest 23 is fixed to the lower nest 24. In this way, it is convenient to disassemble and assemble the pull rope 291, which is conducive to the maintenance and replacement of the pull rope 291.

[0057] Of course, in other embodiments, the end of the pull rope 291 away from the inner nest 23 may be tied to the lower nest 24, or the end of the pull rope 291 away from the inner nest 23 may be welded to the lower nest 24, etc., and the present invention is not limited thereto.

[0058] In one embodiment, see Figure 4 The driving assembly 29 further includes an elastic member 293. The elastic member 293 is sleeved on the inner nest 23 and is located between the inner nest 23 and the sleeve 292. One end of the elastic member 293 is connected to the inner nest 23, and the other end of the elastic member 293 is connected to the sleeve 292. During the folding process of the umbrella, the elastic member 293 can help the inner nest 23 to rotate around the axial direction of the middle rod 21, so as to facilitate the folding of the umbrella.

[0059] Optionally, refer to Figure 4 The elastic member 293 is a scroll spring. The scroll spring is sleeved on the inner nest 23. One end located on the inner side of the scroll spring is connected to the inner nest 23, and the end located on the outer side of the scroll spring is connected to the kit 292. Herein, the inner side of the scroll spring refers to the side of the scroll spring close to the inner nest 23, and the outer side of the scroll spring refers to the side of the scroll spring close to the kit 292.

[0060] In one embodiment, refer to Figure 1 and Figure 2 The secondary rib 27 is further provided with a second limiting member 2714. The second limiting member 2714 is arranged between the upper nest 22 and the secondary connecting member 271. In this way, by providing the second limiting member 2714 on the secondary rib 27, during the umbrella closing process, the second limiting member 2714 can limit the moving distance of the secondary connecting member 271 in the direction close to the upper nest 22.

[0061] Furthermore, refer to Figure 1 and Figure 2 The inner nest 23 and the lower nest 24 move in the axial direction of the middle rod 21 towards the direction close to the upper nest 22, so that the main rib 25 and the secondary rib 27 are in an umbrella opening state. In the umbrella opening state, the secondary connecting member 271 abuts against the second limiting member 2714. When opening the umbrella, push the lower nest 24 in the axial direction of the middle rod 21 towards the direction close to the upper nest 22 until the secondary connecting member 271 abuts against the second limiting member 2714, and then the umbrella opening can be completed.

[0062] In one embodiment, refer to Figure 1 Both the main rib 25 and the secondary rib 27 are provided with a plurality of them. All the main ribs 25 and all the secondary ribs 27 are alternately arranged along the circumferential direction of the upper nest 22. Since the main rib 25 and the secondary rib 27 are alternately arranged along the circumferential direction of the upper nest 22, the umbrella cloth can be better curled in this way.

[0063] It should be noted that the number of the main ribs 25 and the secondary ribs 27 can be set according to actual needs and will not be specifically limited here.

[0064] In this embodiment, refer to Figure 1 Both the main rib 25 and the secondary rib 27 are provided with eight. The eight main ribs 25 and the eight secondary ribs 27 are respectively alternately arranged along the circumferential direction of the upper nest 22.

[0065] In one embodiment, refer to Figure 1 The rib structure 20 further includes a handle 242. The handle 242 is sleeved on the lower nest 24 and connected to the lower nest 24.
