[0032] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific illustrations.

[0033] Combined with Figures 1 to 15 As shown, the present utility model discloses an outdoor Roman umbrella with a novel opening and closing umbrella mechanism, including an umbrella frame 200 and an umbrella column 100. The umbrella frame 200 is located on one side of the umbrella column 100. The umbrella frame 200 generally includes an upper umbrella disc 210, a lower umbrella disc 220, long umbrella ribs 230 and short umbrella ribs 240. One end of the long umbrella rib 230 is hinged with the upper umbrella disc 210, and the other end extends freely outwards. One end of the short umbrella rib 240 is hinged with the lower umbrella disc 220, and the other end is hinged with the middle part of the long umbrella rib 230. The umbrella frame 200 is a commonly used umbrella frame structure in existing Roman umbrellas.

[0034] Among them, a cantilever base 300 is provided on the umbrella column 100, a cantilever 250 is fitted on the cantilever base 300, and the other end of the cantilever 250 is fitted and installed with the umbrella frame 200, specifically usually fitted with the upper umbrella disc 210; it also includes an opening and closing moving mechanism, which is used to drive the cantilever base 300 to move up and down along the umbrella column 100 to realize the adjustment of the position of the umbrella frame 200. In a preferred embodiment, a pull rod seat 110 is also provided on the umbrella column 100, a pull rod 260 is fitted on the pull rod seat 110, and the other end of the pull rod 260 is used to be fitted and installed with the umbrella frame 200. The pull rod 260 and the cantilever 250 are in an "X" cross fit. The other end of the pull rod 260 is usually hinged with the lower umbrella disc 220. By using the "X" cross deformation structure, when the cantilever 250 moves up along the umbrella column 100 with the cantilever base 300, the overall deployment of the umbrella frame 200 can be realized; in another embodiment, the umbrella frame 200 can be opened and closed with a supporting umbrella rope, and the adjustment of the position of the cantilever base 300 is used to realize the adjustment of the inclination angle position of the umbrella frame 200.

[0035] Combined with the above, the opening and closing moving mechanism in this embodiment includes a central screw 800 and a telescopic sleeve assembly 700. The central screw 800 is a lead screw. Among them, the telescopic sleeve assembly 700 moves up and down along the lead screw. The telescopic sleeve assembly 700 includes at least two groups of telescopic sleeve units. In a preferred embodiment, the telescopic sleeve assembly 700 includes two groups of telescopic sleeve units. According to the size specification of the sunshade, the height of the umbrella column 100 and the opening and closing angle, the telescopic sleeve units in the telescopic sleeve assembly 700 can be adjusted correspondingly according to actual needs, such as being set to 3 groups, etc.

[0036] In a specific structure, the central screw 800 is located in the inner cavity of the telescopic sleeve assembly 700. The central screw 800 is generally longer than the telescopic sleeve assembly 700, and usually partially completely located in the inner cavity of the telescopic sleeve assembly 700. The cantilever base 300 is used for fixedly cooperating with the outermost telescopic sleeve unit. One group of telescopic sleeve units can move relative to the central screw 800, so that the telescopic sleeve assembly 700 can be extended or retracted. When the telescopic sleeve assembly 700 changes from the extended state to the retracted state, the cantilever base 300 drives the cantilever 250 to deploy the umbrella frame 200 or adjust the angle of the umbrella frame 200.

[0037] Combined with the above, the number of telescopic sleeve units in the telescopic sleeve assembly 700 is 2, namely the first telescopic sleeve unit 710 and the second telescopic sleeve unit 720. The first telescopic sleeve unit 710 is sleeved outside the second telescopic sleeve unit 720, and the cantilever base 300 is installed in cooperation with the first telescopic sleeve unit 710. The first telescopic sleeve unit 710 can be extended or retracted relative to the second telescopic sleeve unit 720.

[0038] In a specific structure, the first telescopic sleeve unit 710 includes a first telescopic sleeve 711, a guide ring seat 713 located on the first telescopic sleeve 711, and a moving base 712 located in the first telescopic sleeve 711. The moving base 712 is used for cooperating with the central screw 800. When the moving base 712 or the central screw 800 rotates, the moving base 712 moves up and down relative to the central screw 800. Among them, the cantilever base 300 cooperates with the umbrella column 100. A chute is correspondingly provided in the umbrella column 100. The cantilever base 300 is installed in cooperation with the first telescopic sleeve 711. The cantilever base 300 includes a cantilever lifting lug seat 310 for hinged cooperation with the cantilever 250 and a sleeve base 320 for cooperating with the first telescopic sleeve 711. A screw sleeve 321 is arranged in the sleeve base 320. A bearing seat 323 is arranged between the screw sleeve 321 and the sleeve base 320. Among them, a bearing member 322 is usually arranged between the screw sleeve 321 and the upper part of the sleeve base 320. The screw sleeve 321, the sleeve base 320 and the upper part of the first telescopic sleeve 711 are connected through the bearing seat 323. The moving base 712 is fixedly installed in the inner cavity at the upper end of the first telescopic sleeve 711. The first telescopic sleeve 711 can rotate through the plain bearing between the bearing seats 323 at the upper end. When the first telescopic sleeve 711 rotates, the moving base 712 can rotate and does not interfere with the cantilever base 300, and can drive the cantilever base 300 to move synchronously. Among them, the moving base 712 is usually a lead screw nut for cooperating with the central screw 800. As the central screw 800 rotates, the moving base 712 can move up or down along the central screw 800, so as to drive the first telescopic sleeve unit 711 to move up or down synchronously, thereby driving the cantilever base 300 to move up or down in position.

[0039] Combined with the above, the second telescopic sleeve unit 720 includes a second telescopic sleeve 721, a first linkage seat 722 located at the upper end of the second telescopic sleeve 721, and a second linkage seat 723 located at the lower end of the second telescopic sleeve 721. The outer part of the first linkage seat 722 and the inner part of the guide ring seat 713 can be in mutual contact, and the outer part of the second linkage seat 723 and the outer part of the guide ring seat 713 can be in mutual contact; in the specific telescopic movement of the telescopic sleeve assembly 700, when the telescopic sleeve assembly 700 changes from the deployed state to the retracted state, as the central screw 800 rotates, the moving base 712 continuously moves downward, driving the first telescopic sleeve 711 to rotate and move downward. The guide ring seat 713 at the lower port position of the first telescopic sleeve 711 continuously moves downward until the guide ring seat 713 contacts the second linkage seat 723. At this time, the first telescopic sleeve unit 711 and the second telescopic sleeve unit 721 are in the retracted state.

[0040] According to the positional relationship of the cantilever base 300, when continuous downward movement is required, the central screw 800 continuously rotates. After the guide ring seat 713 continuously moves downward, it drives the second linkage seat 723 to continuously move downward, and the second linkage seat 723 drives the second telescopic sleeve 721 to synchronously move downward continuously; in one preferred embodiment, a rotating shaft 610 is also provided, and the rotating shaft 610 can be embedded and retracted into the inner cavity of the second telescopic sleeve 721.

[0041] Conversely, as the central screw 800 reversely rotates, the moving base 712 moves upward. The moving base 712 drives the first telescopic sleeve 711 to move upward, and the cantilever base 300 also moves upward accordingly. After the first telescopic sleeve 711 moves upward, the guide ring seat 713 continuously moves upward until it contacts the outer part of the first linkage seat 722, and the inner part of the wire ring seat 713 contacts and cooperates with the outer part of the first linkage seat 722, synchronously driving the first linkage seat 722 to move upward, causing the second telescopic sleeve 721 to continuously move upward until it moves to the corresponding upper position.

[0042] Combined with the above, a driving mechanism is further included, and the driving mechanism includes an electric driving mechanism 500 or / and a manual driving mechanism 600.

[0043] In one embodiment, the driving mechanism adopts the electric driving mechanism 500. The electric driving mechanism 500 is used to drive the central screw 800 to rotate, so that the telescopic sleeve assembly 700 can be extended or retracted along the central screw 800; the electric driving mechanism 500 includes a driving motor 510 and a coupling 520, and the upper part of the central screw 800 is cooperatively installed with the coupling 520; the driving motor 510 is a commonly used motor component in the prior art.

[0044] An electric opening and closing is formed by combining an electric drive mechanism 500 with an opening and closing movement mechanism, enabling the Roman umbrella to achieve electric opening and closing control.

[0045] Among them, the top of the umbrella column 100 is preferably also equipped with a solar base 400, and a storage battery is provided inside to supply power to the drive motor 510.

[0046] In another preferred embodiment, it further includes a manual drive mechanism 600. The manual drive mechanism 600 is used to drive the telescopic sleeve assembly 700 to rotate, so that the telescopic sleeve assembly 700 can be extended or retracted along the central screw 800.

[0047] In the specific structure, the manual drive mechanism 600 includes a manual drive part 620 and a rotating shaft 610. One end of the rotating shaft 610 is connected to the manual drive part 620, and a rotating seat 611 is provided at the other end of the rotating shaft 610; the rotating seat 611 is in butt joint and cooperation with the telescopic sleeve assembly 700 and can drive the telescopic sleeve assembly 700 to rotate. Preferably, a number of clamping protrusions 612 are provided on the rotating seat 611. Usually, the rotating seat 611 is used to cooperate with the second linkage seat 723. A clamping groove 724 corresponding to the clamping protrusion 612 is provided in the inner cavity of the second linkage seat 723. Among them, an inner cavity groove 725 corresponding to the clamping protrusion 612 is provided in the inner cavity of the second telescopic sleeve 721, so that the rotating seat 611 can be axially moved up and down along the second telescopic sleeve 721. When the rotating shaft 610 drives the rotating seat 611 to rotate, the rotating shaft 611 rotates radially. Whether the clamping protrusion 612 in the rotating seat 611 cooperates with the clamping groove 724 or the inner cavity groove 725, it can drive the second telescopic sleeve 721 to rotate. A tooth cavity 726 is correspondingly provided on the outer side wall of the second telescopic sleeve 721. Combined with the corresponding guide claws 714 provided in the guide ring seat 713, the guide claws 714 are correspondingly matched with the tooth cavity 726, so that 721 can synchronously drive the first telescopic sleeve 711 to rotate, thereby driving the moving base 712 to rotate, so that the moving base 712 can move up and down along the central screw 800.

[0048] Among them, the manual driving part 620 includes a hand-cranking part 623, a transmission gear seat 621 and a transmission coupling 622. The manual driving part 620 is used to drive the rotary shaft 610 to rotate, so that the telescopic sleeve assembly 700 can be telescoped or retracted along the central screw 800; among them, the transmission gear seat 621 and the transmission coupling 622 are common components in the prior art, and the hand-cranking part 623 is usually a handle. The user cranks the handle to drive the transmission of the transmission gear seat 621. With the power input of cranking the handle, the power is output to the transmission coupling 622 through the transmission gear seat 621. The upper part of the transmission coupling 622 is connected to the bottom of the rotary shaft 610, so as to drive the rotary shaft 610 to rotate, and then the opening and closing movement mechanism is matched to realize the opening and closing or position adjustment of the umbrella frame 200.

[0049] Among them, the lower end of the central screw 800 usually extends into the inner cavity of the rotary shaft 610 and is cooperatively installed with the inner cavity of the rotary shaft 610 through a screw bearing 810.

[0050] Combined with the above, in one of the preferred embodiments, the driving mechanism can be selected to have both an electric driving mechanism 500 and a manual driving mechanism 600, or be separately equipped with an electric driving mechanism, or be separately equipped with a manual driving mechanism.

[0051] Optimizing the above structure, the electric driving mechanism drives the selected central screw to rotate, so that the moving base moves in position and drives the rest of the components; the manual driving mechanism drives the overall telescopic sleeve assembly to rotate by the rotary shaft, so that the moving base rotates. At this time, the central screw is in a static state, and the moving base can rotate and then move up and down along the central screw.

[0052] The utility model combines the opening and closing movement mechanism with the driving, which can realize electric driving or / and manual driving, improving the convenience of opening and closing the umbrella surface and the convenience of operation; especially optimizing the opening and closing movement mechanism, using the cooperation between the central screw and the telescopic sleeve assembly, can conveniently drive the cantilever base to move, so that the umbrella frame can be conveniently opened and closed.

[0053] The above description is only a preferred embodiment of the utility model, and does not impose any formal restrictions on the utility model.
