DETAILED DESCRIPTION

[0036] The technical solutions of the present application will be described in detail below with reference to the drawings and specific embodiments, so that the advantages and features of the present application are easier for those skilled in the art to understand. Obviously, the embodiments described in the present application are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0037] Embodiment 1: see Fig. 1 Figure 1The folding umbrella shown in the figure comprises a central rod 1, a top rod 2 and a diagonal support rod 7. The central rod 1 is used to be supported on or fixed to the ground, or the central rod 1 is used to be mounted on a base to achieve fixation. The top rod 2 is connected with the central rod 1, and the top rod 2 is arranged to be able to be unfolded and folded relative to the central rod 1. Two of the three rods, i.e. the diagonal support rod 7, the central rod 1 and the top rod 2, are connected in a rotatable and slidable manner, and the third one is rotatably connected with the above two. In the embodiment, the top rod 2 is rotatably connected with the central rod 1, one end of the diagonal support rod 7 is rotatably connected with the top rod 2, and the other end of the diagonal support rod 7 is rotatably and slidably connected with the central rod 1. When the folding umbrella is in an unfolded state, the top rod 2 is unfolded relative to the central rod 1, and the diagonal support rod 7 is supported between the top rod 2 and the central rod 1. In other embodiments, the top rod 2 is rotatably and slidably connected with the central rod 1, and the diagonal support rod 7 is rotatably connected with the top rod 2 and the central rod 1 respectively; or the top rod 2 is rotatably connected with the central rod 1, one end of the diagonal support rod 7 is rotatably and slidably connected with the top rod 2, and the other end of the diagonal support rod 7 is rotatably connected with the central rod 1.

[0038] The folding umbrella further comprises a side support rod 3 and an umbrella cloth 4. The side support rod 3 is rotatably connected with the top rod 2, and a limiting structure for limiting the rotation angle between the top rod 2 and the side support rod 3 is arranged therebetween. The umbrella cloth 4 has a main body part 41 and a side wall part 42. The main body part 41 is used to cover above the top rod 2, and the side wall part 42 is connected with the outer edge of the main body part 41. The side wall part 42 is connected with the side support rod 3. When the folding umbrella is in an unfolded state, the side support rod 3 extends downward from the top rod 2, and then the side wall part 42 extends downward from the outer edge of the main body part 41 to form a display surface. Referring to Figure 1 As shown, the user can print patterns, advertisements or slogans on the display surface. In the unfolded state, the content on the display surface can be well displayed, so as to achieve the effect of beautification or promotion.

[0039] In the embodiment, the side wall part 42 is fixedly connected with the main body part 41. In some embodiments, the side wall part 42 is detachably connected with the main body part 41, so that the side wall part 42 can be replaced separately. In the embodiment, when the folding umbrella is in the unfolded state, the side support rod 3 is in a state of nearly vertical extension, and the side support rod 3 is nearly parallel to the central rod 1. Here, nearly means to allow a certain angle error.

[0040] In this embodiment, during the unfolding process of the folding umbrella, the top rod 2 unfolds relative to the central rod 1, driving the umbrella fabric 4 to unfold. During this process, the side panel 42 can drive the side support rod 3 to rotate relative to the top rod 2. The top rod 2 continues to unfold until the limiting structure takes effect and prevents the top rod 2 from rotating relative to the side support rod 3. At this point, the umbrella fabric 4 is fully unfolded, and the folding umbrella transitions to the unfolded state. In the unfolded state, the limiting structure maintains stability between the side support rod 3 and the top rod 2, and keeps the side panel 42 in a taut state, allowing for a better display effect. In summary, the unfolding process requires minimal user intervention; simply driving the top rod 2 to unfold relative to the central rod 1 is sufficient. Subsequently, the folding umbrella automatically transitions to the unfolded state under the action of the umbrella fabric 4, the limiting structure, and other components.

[0041] In this embodiment, the push rod 2 includes a plurality of push rods spaced apart circumferentially along the central rod 1, and the plurality of push rods 2 are rotatably connected to the central rod 1. Specifically, a mounting base 11 is fixedly provided on the upper part of the central rod 1, and the plurality of push rods 2 are rotatably connected to the mounting base 11.

[0042] In this embodiment, see Figure 2 As shown, one end of the top rod 2 is rotatably connected to the central rod 1, and the side support rod 3 is rotatably connected to the other end of the top rod 2 away from the central rod. When the folding umbrella is in the unfolded state, see... Figure 1 As shown, the side panel 42 is arranged around the perimeter of the folding umbrella. By setting advertisements, slogans, patterns, etc. on it, a better display effect can be achieved, thereby enriching the function of the folding umbrella or making the folding umbrella more beautiful.

[0043] In this embodiment, when the folding umbrella is in the unfolded state, there is a first angle between the top rod 2 and the side support rod 3. When the folding umbrella is in the folded state, the top rod 2 and the side support rod 3 are respectively retracted relative to the center rod 1, and there is a second angle between the top rod 2 and the side support rod 3 that is greater than the first angle. See also Figure 3 ,superior Figure 4 As shown, when the folding umbrella is in the folded state, the top rod 2 and the side support rod 3 unfold relative to each other, allowing the side support rod 3 to transition as parallel to the central rod 1 as possible. This enables the top rod 2 and the side support rod 3 to more compactly fold relative to the central rod 1, thereby reducing the volume of the folded umbrella. In a preferred embodiment, when the folding umbrella is in the folded state, the side support rod 3 and the central rod 1 are parallel to each other, although there is a certain angular deviation in their parallel operation.

[0044] In the embodiment, the limiting structure comprises a support rod 5, one end of the support rod 5 is connected with the top rod 2, and the other end of the support rod 5 is connected with the side support rod 3. When the folding umbrella is in the unfolded state, the support rod 5 is supported between the top rod 2 and the side support rod 3, the relative rotation of the two is prevented by the support rod 5, and the stability between the top rod 2 and the side support rod 3 is maintained by the support rod 5. In some embodiments, one of the top rod 2 and the side support rod 3 is rotatably connected with the support rod 5, the other one is slidably connected with the support rod 5, and specifically, the other one is rotatably and slidably connected with the support rod 5. By setting one end of the support rod 5 to be slidable, the support rod 5 can also cooperate with the relative rotation of the top rod 2 and the side support rod 3 by sliding while realizing the support and limiting functions.

[0045] In the embodiment, the side support rod 3 is provided with a sliding groove 31, one end of the support rod 5 is movably inserted in the sliding groove 31, and the other end of the support rod 5 is rotatably connected with the top rod 2. Referring to Figure 5 When the folding umbrella is in the unfolded state, the support rod 5 abuts against the side support rod 3. Specifically, when the folding umbrella is in the unfolded state, the sliding groove 31 extends in the up-down direction, the support rod 5 abuts against the groove wall on the lower side of the sliding groove 31, and a triangular structure is formed between the top rod 2, the side support rod 3 and the support rod 5, so that the three maintain stability and prevent the relative rotation of the top rod 2 and the side support rod 3. Specifically, the sliding groove 31 extends along the length direction of the side support rod 3, the support rod 5 has a first end 51 and a second end 52 which are separately arranged at two different ends in the length direction, the first end 51 is rotatably connected with the top rod 2, and the second end 52 is provided with a sliding pin 53 which extends perpendicularly to the length direction of the side support rod 3, the sliding pin 53 is movably inserted in the sliding groove 31, and the support rod 5 can also rotate relative to the side support rod 3 about the sliding pin 53.

[0046] In the embodiment, the top rod 2 has a receiving groove 21 which extends along the length direction of the top rod 2, and one end of the support rod 5 is inserted in the receiving groove. Referring to Figure 4 When the folding umbrella is in the folded state, the support rod 5 is close to the top rod 2, and at least part of the support rod 5 is accommodated in the receiving groove 21, which not only can reduce the size of the space occupied by the top rod 2 and the support rod 5, but also can make the top rod 2 more compactly close to the central rod 1, thereby achieving the effect of reducing the volume of the folding umbrella in the folded state.

[0047] Specifically, referring to Figure 6 , Figure 7As shown, the top rod 2 comprises a top wall 22 and two side walls 23 arranged on both sides of the top wall 22, and a U-shaped slot is formed between the top wall 22 and the two side walls 23. In some embodiments, the U-shaped slot between the top wall 22 and the two side walls 23 constitutes the accommodating slot 21 described above. In this embodiment, the top rod 2 comprises a first reinforcing structure 24 connected between the two side walls 23, and the top rod 2 further comprises a second reinforcing structure 25 connected between the first reinforcing structure 24 and the top wall 22, and the first reinforcing structure 24 and the second reinforcing structure 25 are both used to improve the structural strength of the top rod 2, thereby improving the stability of the folding umbrella. In this embodiment, the first reinforcing structure 24 is in the shape of a long strip, and the first reinforcing structure 24 and the two side walls 23 form the accommodating slot 21 described above, and the opening of the accommodating slot 21 faces away from the top wall 22.

[0048] In this embodiment, the elastic member 6 is arranged between the top rod 2 and the side rod 3, and the elastic member 6 is used to provide the force required to drive the side rod 3 to rotate relative to the top rod 2 to increase the included angle therebetween. When the folding umbrella is converted from the unfolded state to the folded state, the side rod 3 automatically rotates relative to the top rod 2 and unfolds relative to the top rod 2 under the action of the elastic member 6, without the need for user operation, and the user only needs to drive the top rod 2 to fold relative to the center rod 1 to complete the folding of the folding umbrella. Specifically, in this embodiment, referring to Figure 6 As shown, the elastic member 6 is a torsion spring arranged between the top rod 2 and the side rod 3.

[0049] In this embodiment, the folding umbrella comprises a sliding member 12 which is slidingly arranged on the center rod 1, one end of the diagonal rod 7 is rotatably connected with the top rod 2, and the other end of the diagonal rod 7 is rotatably connected with the sliding member 12. When the folding umbrella is in the folded state, the diagonal rod 7 is folded between the center rod 1 and the top rod 2. When unfolding the folding umbrella, the user drives the sliding member 12 to slide along the center rod 1, so that the sliding member 12 is closer to the mounting base 11, and the sliding member 12 drives the top rod 2 to unfold relative to the center rod 1 through the diagonal rod 7, and when the sliding member 12 moves to a preset position, the folding umbrella is converted to the unfolded state. When folding the folding umbrella, the sliding member 12 is driven to slide in the opposite direction, away from the mounting base 11 until it moves to the preset position.

[0050] In this embodiment, the folding umbrella is provided with a handle 9 which is rotatably connected with the center rod 1, and a linkage assembly is arranged between the handle 9 and the sliding member 12, so that the user can drive the sliding member 12 to slide along the center rod 1 by rotating the handle 9, thereby achieving the conversion between the unfolded state and the folded state of the folding umbrella by rotating the handle 9. The unfolding angle of the top rod 2 relative to the center rod 1 can also be changed through the handle 9, thereby adjusting the unfolding degree and the shielding area of the folding umbrella.

[0051] In the embodiment, the side support rod 3 is provided with a hook 32.
