[0027] It should be further understood that the term "and / or" used in the description and appended claims of the present invention refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0028] As Figures 1 to 4 shown, an umbrella rib group includes an upper nest 1, a lower nest 2, long ribs 3 and short ribs 4. The umbrella rib support group is placed in a special mold and completed by a dedicated machine in one combination. When it leaves the machine, the assembly is completed and formed into an umbrella rib support group, with a simple and lightweight structure, which can save complicated parts processing and assembly procedures. The long ribs 3 and short ribs 4 are arranged in pairs and there are multiple pairs. Both the long ribs 3 and short ribs 4 are hollow structures to reduce the overall weight of the umbrella rib group and make the umbrella more lightweight and easy to carry. The hollow structures of the long ribs 3 and short ribs 4 can be filled with lightweight filling materials such as polyurethane foam to enhance the structural strength while ensuring light weight.

[0029] The first ends of the long ribs 3 are each provided with a first bending joint 5. One end of the first bending joint 5 is fixedly installed on the first end of the long rib 3, and the other end is provided with a first hook groove 51. The upper nest 1 is provided with first hooks 11 having the same number as the long ribs 3. The first hooks 11 are in snap-fit connection with the first hook grooves 51 one by one to realize the connection between the long ribs 3 and the upper nest 1, so that the long ribs 3 are bent 180° relative to the upper nest 1.

[0030] The first ends of the short ribs 4 are each provided with a second bending joint 6, and the second ends are each provided with a third bending joint 7. Among them, one end of the second bending joint 6 is fixedly installed on the first end of the short rib 4, and the other end is provided with a second hook groove 61. The lower nest 2 is provided with second hooks 21 having the same number as the short ribs 4. The second hooks 21 are in snap-fit connection with the second hook grooves 61 one by one to realize the connection between the short ribs 4 and the lower nest 2, so that the short ribs 4 are bent 180° relative to the lower nest 2. At the same time, one end of the third bending joint 7 is fixedly installed on the second end of the short rib 4, and the other end is fixedly connected to the middle section of the long rib 3 to realize the connection between the short rib 4 and the long rib 3, so that the short rib 4 is bent 180° relative to the long rib 3.

[0031] The process of closing or opening the umbrella rib group of the present application is as follows:

[0032] When it is necessary to open the umbrella rib group, the lower nest 2 is driven by an external force to move away from the upper nest 1, and the lower nest 2 drives the first end of the short rib 4 to move in the same direction; during the movement of the short rib 4, the first end bends relative to the lower nest 2, and the second end bends relative to the long rib 3. When the lower nest 2 moves to the designated position, that is, when the first end of the short rib 4 moves to a position close to the second end of the long rib 3, the short rib 4 and the long rib 3 are close to parallel, realizing the retraction of the umbrella rib group.

[0033] When it is necessary to open the umbrella rib group, the lower nest 2 is driven by an external force to move closer to the upper nest 1, and the lower nest 2 drives the first end of the short rib 4 to move in the same direction; during the movement of the short rib 4, the first end bends relative to the lower nest 2, and the second end bends relative to the long rib 3 and jacks up the long rib 3, realizing the opening of the umbrella rib group.

[0034] The advantages of the umbrella rib group of the present application are as follows: through the cooperation of specific hooks and hook grooves and the structure of the bending joint, reliable connections between the long rib 3 and the upper nest 1, the short rib 4 and the lower nest 2, and the short rib 4 and the long rib 3 are realized, reducing the loosening and falling off of components during use, effectively preventing the separation of the ribs from the nest body, and improving the stability of the umbrella; it also has the characteristics of simple and light structure, easy assembly, and high practicability.

[0035] In the specific implementation process of the present application, refer to Figure 3 , the upper nest 1 is provided with an installation hole 12 for installing the upper nest 1 at the top of the umbrella handle 8. A uniformly distributed first insertion hole 13 is provided on the outer periphery of the installation hole 12, and the number of the first insertion holes 13 corresponds to the number of the long ribs 3 for inserting the first ends of the long ribs 3 into them one by one. The first hook 11 is arranged in the first insertion hole 13, and the first hook 11 is provided with a guiding part to facilitate the smooth insertion of the long rib 3. One end of the first bending joint 5 having the first hook groove 51 is inserted into the first insertion hole 13, and the first hook 11 and the first hook groove 51 are engaged with each other to realize the fixed connection between the long rib 3 and the upper nest 1.

[0036] In the specific implementation process of the present application, refer to Figure 4 , the lower nest 2 is provided with a through hole 22 for passing through the umbrella handle 8 and enabling the lower nest 2 to slide up and down along the umbrella handle 8. A uniformly distributed second insertion hole 23 is provided on the outer periphery of the through hole 22, and the number of the second insertion holes 23 corresponds to the number of the short ribs 4 for inserting the first ends of the short and long ribs 3 into them one by one. The second hook 21 is arranged in the second insertion hole 23, and the second hooks 21 are all provided with guiding parts to facilitate the smooth insertion of the short rib 4. One end of the second bending joint 6 having the second hook groove 61 is inserted into the second insertion hole 23, and the second hook 21 and the second hook groove 61 are engaged with each other to realize the fixed connection between the short rib 4 and the lower nest 2.

[0037] In addition, elastic buffer pads are respectively arranged in the first insertion hole 13 and the second insertion hole 23. The elastic buffer pads are made of rubber material and are used to buffer the impact force when the bending joint is inserted, reducing the impact and wear between components.

[0038] Based on the same inventive concept as the above umbrella rib group, the embodiment of the present application further provides an umbrella, see Figures 5 to 7 , including an umbrella handle 8, an umbrella cloth 9, and the umbrella rib group as described in any one of the above. The upper nest 1 is fixedly installed at the top of the umbrella handle 8; the umbrella handle 8 passes through the lower nest 2, and the lower nest 2 slides up and down relative to the umbrella handle 8; the umbrella cloth 9 is arranged on the long rib 3. A grip 81 is provided at the bottom end of the umbrella handle 8, and anti-slip textures are provided on the surface of the grip 81 to increase the comfort and stability of holding. During actual use, the user holds the grip 81 at the bottom end of the umbrella handle 8 and realizes the opening and closing of the umbrella by sliding the lower nest 2 up and down. The principle of the opening and closing process of the umbrella is the same as that of the folding or unfolding process of the umbrella rib group, which will not be elaborated here.

[0039] In addition, see Figure 5 , a bead tail 31 of the umbrella rib is provided at the second end of the long rib 3 for spot sewing and fixing of the umbrella cloth 9, facilitating the installation of the umbrella cloth 9.
