[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0043] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0044] See also Figure 1 to Figure 6 The present application provides an umbrella frame 1000, which has an unfolded state and a folded state. Figure 2 In the H direction shown, the direction indicated by the H arrow is upward.

[0045] The umbrella frame 1000 includes a central umbrella plate assembly 200 and a plurality of rib assemblies 300 connected to the umbrella plate assembly 200 and arranged radially. The rib assemblies 300 and the umbrella plate assembly 200 are connected in a movable manner to meet the folding or unfolding movement, and the connection method is, for example, hinged. "Radial" is understood to mean that Figure 3 As shown in the vertical projection, the rib assembly 300 extends in the radial direction.

[0046] The rib assembly 300 includes a first rib 310 and a second rib 320 which are relatively fixed and have a gap in the height direction when in the unfolded state. The first rib 310 is higher than the second rib 320. The first rib 310 and the second rib 320 have a fixed end 301 and a free end 302 which are opposite to each other. The first rib 310 and the second rib 320 are relatively fixed. The relatively fixed position may be one or more positions, a continuously extended section or a plurality of positions arranged at intervals. "Relatively fixed" is understood to mean that at least the position or area where the first rib 310 and the second rib 320 are fixed maintains a constant spatial position during the switching between the unfolded and folded states. "Having a gap" means that there is a gap at least partially between the two ribs, so that there is a cavity between the umbrella cloths supported by the two ribs.

[0047] In the umbrella frame of the present application, the first rib and the second rib are relatively fixed, which simplifies the structure of the umbrella frame and improves manufacturing efficiency.

[0048] The umbrella frame 1000 in the present application can be used to manufacture a double-layer umbrella 2000, for example Figure 4 and Figure 5 , the first umbrella cloth 410 is lined on each first umbrella rib 310, and the edge of the first umbrella cloth 410 is fixedly connected to the free end of the first umbrella rib 310; similarly, the second umbrella cloth 420 is lined on each second umbrella rib 320, and the edge of the second umbrella cloth 420 is fixedly connected to the free end of the second umbrella rib 320. The second umbrella cloth 420 is lower than the first umbrella cloth 410, and the second umbrella cloth 420 has a vent 421. In the vertical projection direction, the first umbrella cloth 410 covers the vent 421. The interval between the two umbrella ribs forms a cavity 330 between the two umbrella cloths. In the unfolded state, the cavity 330 and the vent 421 are connected to form a channel for air flow. The first umbrella cloth 410 covers the vent 421 to prevent raindrops from entering the vent. In the figure, the first umbrella rib 310 and the second umbrella rib 320 are inclined downward from the center to the edge. Due to the shape of the umbrella cloth, in the unfolded state, the second umbrella cloth 420 drives the second umbrella rib 320 to deform, so that the opening of the compartment 330 is larger than that in the folded state.

[0049] In one embodiment, the relative fixation of the first rib 310 and the second rib 320 can be achieved by binding wire or by a fixed connection through a first connecting seat 340 as shown in the figure. After the first rib 310 and the second rib 320 are fixedly connected, the fixed ends of the two ribs are directly or indirectly hinged to the umbrella plate assembly 200. The direct hinged connection is in the form of the end of the rib itself being hinged to the umbrella plate assembly 200; the indirect hinged connection is in the form of the rib being hinged to the umbrella plate assembly 200 through other components. For example, the fixed ends of the first rib 310 and the second rib 320 are plugged and fixed to the first connecting seat 340, and then the first connecting seat 340 is hinged to the umbrella plate assembly 200. The first connecting seat 340 serves to fix the two ribs and also takes into account the connection with the umbrella plate assembly, thereby further improving the manufacturing efficiency.

[0050] In some embodiments, the first rib 310 and the second rib 320 are overlapped in the height direction, that is, the two ribs overlap each other in vertical projection without misalignment in the height direction, but the interval between the two ribs is still retained.

[0051] Further preferably, the two ribs and the first connecting seat can be reinforced by applying glue, so that compared with the existing structure, the overall structure is simpler and easier to assemble.

[0052] In one embodiment, the umbrella plate assembly 200 includes an upper plate 210 and a lower plate 220, the first connecting seat 340 is hinged to the upper plate 210, and the rib assembly 300 includes a third rib 350 whose two ends are respectively hinged to the lower plate 220 and the second rib 320. When unfolded, the third rib 350 drives the second rib 320 to deform away from the first rib 310, so that the opening of the compartment 330 is enlarged, which is convenient for airflow in and out. The second rib 320 is bent into an arc under the restriction of the second umbrella cloth 420. The second rib 320 is fixedly provided with a second connecting seat 321, and the third rib 350 is hinged to the second connecting seat 321.

[0053] Among them Fig. 9 and Fig.10 The first rib 310 and the second rib 320 are straight rods. When the umbrella frame is folded, the first rib 310 and the second rib 320 are parallel or at an angle α to each other as shown in the figure. The angle α satisfies 1 to 5 degrees (such as Fig.10 In this embodiment, the first rib 310 and the second rib 320 are parallel (as shown in FIG. Fig. 9 As shown in the figure), and the minimum distance between the two is L1 as shown in the figure, and L1 satisfies 1-5 mm. In one embodiment, along the extension direction of the ribs themselves, the distance between the free end of the first rib 310 and the center of the umbrella frame is smaller than the distance between the free end of the second rib 320 and the center of the umbrella frame. Combined with the above, in vertical projection, the first umbrella cloth 410 is within the projection edge contour of the second umbrella cloth 420.

[0054] In one embodiment, the umbrella frame 1000 includes an umbrella pole 100, and the umbrella pole 100 is fixedly connected to one of the upper plate 210 and the lower plate 220, and the other plate is provided with a through hole for the umbrella pole 100 to pass through. Several embodiments are provided below, for example:

[0055] Embodiment 1: The umbrella pole 100 is connected to the upper plate 210, and the lower plate 220 has a perforation;

[0056] Embodiment 2: The umbrella pole 100 is connected to the lower plate 220, and the upper plate 210 has a perforation.

[0057] Among them Figure 7 As shown, based on the first embodiment, the umbrella pole 100 can extend to the lower plate 220 to form a handle 110, and the lower plate 220 is slidably mounted on the umbrella pole 100.

[0058] Or Figure 8As shown, on the basis of embodiments one and two, the umbrella frame 1000 includes a head ring 500 worn on the head when in use, and the head ring 500 is connected to the umbrella rib assembly 300 through a support rod 510. The umbrella frame shown in the figure is based on embodiment two, and there are multiple support rods 510 and they correspond one to one with the third umbrella rib 350. One end of the support rod 510 is hinged to the third umbrella rib 350. The head ring 500 is a flexible belt or other existing technology, and the head ring 500 is connected to the other end of each support rod 510.

[0059] In the umbrella frame of the present application, the first rib and the second rib are relatively fixed, which not only simplifies the structure but also improves the assembly efficiency and can prevent the two ribs from being misaligned when in the unfolded state.

[0060] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0061] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
