Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the priority benefit of China applications serial no. 202422902249.3 and 202422897454.5, filed on Nov. 27, 2024. The entirety of each of the above-mentioned patent applications is hereby incorporated by reference herein and made a part of this specification.TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of outdoor umbrellas, and in particular to an outdoor sun-shading umbrella having a novel unfolding and folding lifting mechanism.BACKGROUND

[0003] A Roman umbrella, also known as a 360-degree rotating umbrella, is an outdoor sun-shading umbrella with the most powerful function, which can rotate by 360 degrees horizontally or 90 degrees vertically. Use of the Roman umbrella is the most creative and casual way to shade the sun in the Chinese market. Compared with other umbrellas, the Roman umbrella has a better sun-shading effect and is more convenient to operate.

[0004] A general Roman umbrella includes a vertical rod and an umbrella cover assembly, where the umbrella cover assembly includes a middle rod, cross rods, an upper umbrella disc, a lower umbrella disc and an umbrella cover. When the umbrella is folded, a height of the upper umbrella disc is not changed, and the cross rods are folded by moving the lower umbrella disc upwards, such that an umbrella folding function is realized. At present, large sun-shading umbrellas in the market have large umbrella covers, umbrella ribs are close to the ground when the umbrella is folded, the umbrella ribs are likely to touch a table and articles on the table under the umbrella when the umbrella is unfolded and folded, but the sun-shading effect cannot be achieved if an umbrella edge is too high.

[0005] Therefore, for example, a Roman umbrella with an umbrella cover convenient to contract is disclosed in the patent with the publication No. CN109619782A. The Roman umbrella includes an umbrella cover assembly and a vertical rod assembly which are connected in a cooperative manner, where the umbrella cover assembly includes a middle rod, an upper umbrella disc, a lower umbrella disc, a group of first cross rods and a group of second cross rods which are connected in a cooperative manner. The upper umbrella disc is hinged to a first inclined pull rod, a middle of the first inclined pull rod is hinged to a second inclined pull rod, and a lower end of the first inclined pull rod is hinged to a sliding portion. The vertical rod assembly includes an outer vertical rod, an inner telescopic rod, a traction device and an elastic element. Such a Roman umbrella is reasonable in design and compact in structure. The structure of the Roman umbrella enables the position of the upper umbrella disc to move upwards in an umbrella folding process, thereby raising a height of the whole umbrella cover assembly, such that the umbrella cover assembly is less likely to touch a table under the umbrella and articles on the table. Moreover, through such a structure, a height of an umbrella edge does not need to be raised, thereby avoiding a poor sun-shading effect caused by the too high umbrella edge height.

[0006] However, in the above structure, umbrella post lifting needs to cooperate with internal multi-stage pulleys for sliding traction, such that the overall structure is relatively complex. When the umbrella is unfolded and folded, a user needs large operating force, which affects use performance, and the manufacturing cost is also relatively high.SUMMARY

[0007] Aiming at the above problems, the present disclosure aims at providing an outdoor sun-shading umbrella having a novel unfolding and folding lifting mechanism or an electric outdoor sun-shading umbrella, such that lifting supporting is achieved through changes of a pull rod during unfolding and folding of the umbrella in combination with a supporting rod, a lifting structure of an umbrella post lifting assembly is simplified, and good lifting stability is achieved.

[0052] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present disclosure, the present disclosure is further described in combination with particular diagrams.Example 1

[0053] As shown in FIG. 1 to FIG. 22, an outdoor sun-shading umbrella having a novel unfolding and folding lifting mechanism is disclosed in the present disclosure. The outdoor sun-shading umbrella includes an umbrella stand 200 and an umbrella post 100, where the umbrella stand 200 is positioned at one side of the umbrella post 100. The umbrella stand 200 generally includes an upper umbrella disc 210, a lower umbrella disc 220, long umbrella ribs 230 and short umbrella ribs 240, one ends of the long umbrella ribs 230 are hinged to the upper umbrella disc 210, and the other ends of the long umbrella ribs are freely extended outwards. One ends of the short umbrella ribs 240 are hinged to the lower umbrella disc 220, and the other ends of the short umbrella ribs are hinged to middles of the long umbrella ribs 230. The umbrella stand 200 is of a common umbrella stand structure in an existing Roman umbrella.

[0054] A cantilever base 300 is arranged on the umbrella post 100, the cantilever base 300 is provided with a cantilever 250 for cooperation, the other end of the cantilever 250 and the umbrella stand 200 are mounted for cooperation, and particularly, the cantilever generally cooperates with the upper umbrella disc 210. A pull rod seat 110 is further arranged on the umbrella post 100, a pull rod 260 is arranged the pull rod seat 110 for cooperation, and the other end of the pull rod 260 is used for cooperating with the umbrella stand 200 for mounting. The cantilever 250 cooperates with the pull rod 260 at a middle, where one structure is that the pull rod 260 and the cantilever 250 are in an X-cross fit, and the other end of the pull rod 260 is usually hinged to the lower umbrella disc 220. By using the X-cross deformation structure, the cantilever 250 moves upwards along the umbrella post 100 along with the cantilever base 300, such that the umbrella stand 200 can be unfolded as a whole. In another example, both ends of the pull rod 260 cooperate with the cantilever 250 and the pull rod base 110 respectively, the umbrella stand 200 can be unfolded and folded in cooperation with an umbrella rope, and position adjustment of the cantilever base 300 is used for realizing position adjustment of an inclined angle of the umbrella stand 200. This structure is an existing common Roman umbrella structure.

[0055] To sum up, an umbrella post lifting assembly is arranged between the pull rod 260 and the umbrella post 100 for cooperation, the pull rod seat 110 is arranged on the umbrella post lifting assembly, and the pull rod seat 110 is used for cooperating with the pull rod 260 in a hinged manner. The umbrella post lifting assembly is located at an upper portion of the umbrella post 100, and the umbrella post lifting assembly is capable of moving up and down relative to the umbrella post 100. The outdoor sun-shading umbrella further includes a supporting rod 900, one end of the supporting rod 900 cooperates with the umbrella post 100 in a hinged manner, and the other end of the supporting rod cooperates with a middle of the pull rod 260 in a hinged manner. When the outdoor sun-shading umbrella is folded, an included angle between the supporting rod 900 and the pull rod 260 gradually increases, such that the pull rod 260 drives the pull rod seat 110 to be lifted upwards, and the umbrella post lifting assembly is lifted upwards along the umbrella post 100. When the outdoor sun-shading umbrella is in an unfolding state, the umbrella stand 200 is generally driven to be unfolded as the cantilever base 300 is lifted along the umbrella post 100. As the cantilever base 300 moves upwards, the cantilever 250 usually moves from a quasi-vertical state to a horizontal state, and the pull rod 260 is driven to move from a quasi-vertical state to a horizontal state. Since the joint between the supporting rod 900 and the umbrella post 100 is at a fixed point position, the supporting rod 900 moves synchronously. As the relative positions of the cantilever 250, the pull rod 260 and the supporting rod 900 move, the upper end of the pull rod 260, i.e. the position of the pull rod seat 110 needs to move downwards in order to realize the overall linkage fit, and therefore, the umbrella post lifting assembly moves downwards along the umbrella post 100. To make the umbrella post lifting assembly move upwards along the umbrella post 100, reserve movement is made.

Along with the upward movement of the pull rod seat 110, the outer umbrella post 120 and the inner umbrella post 130 can be synchronously driven to move. By using the combination of the outer umbrella post 120 and the inner umbrella post 130, the upward movement or downward movement of the umbrella post lifting assembly along the umbrella post 100 can be more stable and effective.

[0057] A first supporting rod hinged seat 920 is fixed on the umbrella post 100, and the first supporting rod hinged seat 920 is used for cooperating with one end of the supporting rod 900 in a hinged manner.

In another example, the umbrella stand 200 can be unfolded and folded in cooperation with an umbrella rope, and position adjustment of the cantilever base 300 is used for realizing position adjustment of an inclined angle of the umbrella stand 200.

[0067] To sum up, the unfolding and folding moving mechanism in this example includes a central screw rod 800 and a telescopic sleeve assembly 700, and the central screw rod 800 is a lead screw. The telescopic sleeve assembly 700 moves up and down along the lead screw. The telescopic sleeve assembly 700 includes at least two telescopic sleeve units. In a preferred example, the telescopic sleeve assembly 700 includes two telescopic sleeve units. According to the size specification of the sun-shading umbrella, and a height and an unfolding and folding angle of the umbrella post 100, the telescopic sleeve units in the telescopic sleeve assembly 700 can be correspondingly adjusted according to actual needs, for example, three telescopic sleeve units are arranged.

[0068] In a specific structure, the central screw rod 800 is positioned in an inner cavity of the telescopic sleeve assembly 700, a length of the central screw rod 800 is generally greater than that of the telescopic sleeve assembly 700, and, the central screw rod is generally partially completely within the inner cavity of the telescopic sleeve assembly 700. The cantilever base 300 is used for fixedly cooperating with the telescopic sleeve unit arranged on the outermost side in a sleeving manner, and one telescopic sleeve unit and the central screw rod 800 realize relative movement, such that the telescopic sleeve assembly 700 is capable of being stretched or folded. When the telescopic sleeve assembly 700 is changed from the stretched state to the retracted state, the cantilever base 300 drives the cantilever 250 to realize unfolding of the umbrella stand 200 or angle adjustment of the umbrella stand 200.

[0069] To sum up, the telescopic sleeve assembly 700 has two telescopic sleeve units, namely a first telescopic sleeve unit 710 and a second telescopic sleeve unit 720, the first telescopic sleeve unit 710 is arranged outside the second telescopic sleeve unit 720 in a sleeving manner, and the cantilever base 300 is mounted in cooperation with the first telescopic sleeve unit 710.

The cantilever base 300 cooperates with the umbrella post 100, a sliding groove is correspondingly provided in the umbrella post 100, and the cantilever base 300 is mounted in cooperation with the first telescopic sleeve 711. The cantilever base 300 includes a cantilever lug seat 310 for cooperating with the cantilever 250 in a hinged manner and a sleeve base 320 for cooperating with the first telescopic sleeve 711. A screw rod sleeve 321 is arranged in the sleeve base 320, and a bearing seat 323 is arranged between the screw rod sleeve 321 and the sleeve base 320 for cooperation. A bearing member 322 is usually arranged between the screw rod sleeve 321 and an upper portion of the sleeve base 320 for cooperation, and the screw rod sleeve 321, the sleeve base 320 and an upper portion of the first telescopic sleeve 711 are connected through the bearing seat 323. The moving base 712 is fixedly mounted in an inner cavity of an upper end of the first telescopic sleeve 711, and the upper end of the first telescopic sleeve 711 can rotate through a plane bearing between two portion of the bearing seat 323, such that when the first telescopic sleeve 711 rotates, the moving base 712 can rotate without interference with the cantilever base 300, and the cantilever base 300 can be synchronously driven to move. The moving base 712 is usually a lead screw nut for cooperating with the central screw rod 800. With rotation of the central screw rod 800, the moving base 712 can move up or down along the central screw rod 800, such that the first telescopic sleeve unit 711 can be driven to move up or down synchronously, thereby driving the cantilever base 300 to move up or down.

[0071] To sum up, the second telescopic sleeve unit 720 includes a second telescopic sleeve 721, a first linkage seat 722 located at an upper end of the second telescopic sleeve 721 and a second linkage seat 723 located at a lower end of the second telescopic sleeve 721, an outer side portion of the first linkage seat 722 and an inner side portion of the guide ring seat 713 are capable of forming mutual collision, and an outer side portion of the second linkage seat 723 and an outer side portion of the guide ring seat 713 are capable of forming mutual collision. During the specific telescopic movement of the telescopic sleeve assembly 700, when the telescopic sleeve assembly 700 changes from the stretched state to the retracted state, along with the rotation of the central screw rod 800, the moving base 712 continues to move downwards to drive the first telescopic sleeve 711 to rotate downwards, and the guide ring seat 713 at a lower port of the first telescopic sleeve 711 continues to move downwards until the guide ring seat 713 collides with the second linkage seat 723.

[0073] On the contrary, with the reverse rotation of the central screw rod 800, the moving base 712 moves upwards, the moving base 712 drives the first telescopic sleeve 711 to move upwards, and the cantilever base 300 also moves upwards. With the upward movement of the first telescopic sleeve 711, the guide ring seat 713 continues to move upwards until the guide ring seat collides with the outer side portion of the first linkage seat 722, such that the inner side portion of the guide ring seat 713 collides with the outer side portion of the first linkage seat 722.
