Description

Technical Field

[0001] This utility model belongs to the field of sunshade technology, specifically relating to a sunshade with an electric opening structure. Background Technology

[0002] Outdoor umbrellas, also known as sun umbrellas, parasols, Roman umbrellas, center-pole umbrellas, banana umbrellas, etc., are widely used in leisure places such as squares, beaches, parks, and courtyards, providing people with comfortable spaces for relaxation and shade.

[0003] The structure of an outdoor umbrella typically includes a base, umbrella posts, canopy, canopy tray, and ribs. The umbrella posts are used for vertical support, and the canopy usually covers the ribs. The umbrella is opened or closed by closing the ribs. However, existing umbrella rib structures, regardless of the type of outdoor umbrella, usually require long ribs and short ribs. The long ribs support the canopy, while the short ribs support the long ribs at an angle. Typically, one end of the short ribs is hinged to the lower canopy tray, and the other end is hinged to the long rib, facilitating the folding of the entire umbrella.

[0004] Electric umbrellas are sunshades that are opened and closed by electric power. For example, CN105795636B discloses a solar-powered wind-controlled electric sunshade that can be opened and closed by electric power through manual remote control by the user or by detecting the ambient wind force and setting the solar panel to generate electricity. However, the opening structure and rib assembly of this sunshade include short ribs, which reduces the overall aesthetics of the sunshade. At the same time, due to their own structure, short ribs are usually less strong and are prone to damage, thus affecting the normal use of the sunshade.

[0005] However, when existing outdoor umbrellas are fully opened, the short ribs usually radiate outwards from the center, providing support while being located at the bottom center of the umbrella canopy. For an opened outdoor umbrella, the shape of the short ribs is unavoidable. Moreover, in existing umbrella rib storage structures, the support design of the short ribs is a core component of umbrella rib storage. No umbrella frame structure without short ribs has been found in existing outdoor umbrellas. The support of the short ribs will inevitably affect the overall aesthetic appearance of the bottom of the umbrella canopy. Utility Model Content

[0006] To address the aforementioned issues, this utility model aims to provide a sun umbrella with an electrically operated opening structure. It optimizes the umbrella ribs and opening structure, eliminating the need for a short umbrella rib structure, thereby improving the overall aesthetics and structural strength of the sun umbrella. At the same time, the electrically operated opening design makes the opening process more convenient and effortless. The addition of umbrella rib buffer components can cushion and protect the various parts of the opening mechanism, extending the service life of the sun umbrella.

[0007] The technical problem solved by this utility model can be achieved by the following technical solution: A sun umbrella with an electric opening structure includes several umbrella rib components, umbrella columns, a base, and an opening mechanism. The opening mechanism includes a drive component, several transmission components, and several fixed supports. The drive component includes a drive part, a lead screw, and a lifting platform. The drive part drives the lead screw to rotate. The lifting platform cooperates with the lead screw and moves up and down with the lead screw. The transmission component includes a linkage arm, a first driven part, and a second driven part. The second driven part is connected to the umbrella rib components. The linkage arm cooperates with the lifting platform, the first driven part, the second driven part, and the fixed supports and moves up and down with the lifting platform, driving the second driven part and the umbrella rib components to move, thereby realizing the opening and closing of the umbrella rib components.

[0008] The lifting platform includes a lead screw nut and a lifting seat body. The lead screw nut is installed in the lifting seat body and is used to cooperate with the lead screw. The lifting seat body is used to cooperate with the linkage arm.

[0009] The linkage arm includes a first linkage part, a second linkage part, a third linkage part, and a fourth linkage part. The lifting seat body is provided with several connecting grooves. The first linkage part is disposed in the connecting groove and is hinged to the lifting seat body. The second linkage part is hinged to the upper end of the first driven part. The second driven part includes a gear part. The third linkage part is provided with several teeth. The third linkage part is meshed with the second driven part. The fourth linkage part is hinged to the middle of the fixed bracket.

[0010] The umbrella opening mechanism also includes an umbrella rib buffer assembly, which includes several buffer springs. The buffer springs are installed in conjunction with the upper spring seat on the upper part of the fixed bracket, and the lower end of the buffer springs is installed in conjunction with the lower spring seat on the sliding member. The lower part of the fixed bracket is provided with a sliding groove, and the sliding member is in conjunction with the sliding groove. The lower end of the first driven part is installed in conjunction with the sliding member.

[0011] The transmission component is used to cooperate with the umbrella rib buffer component, which can cause the transmission component to undergo transmission deformation. When the umbrella rib component is subjected to external force, the transmission component drives the sliding component to move along the sliding groove.

[0012] The umbrella rib assembly includes an umbrella rib connecting part, and a second driven part is disposed in the umbrella rib connecting part and hinged to the upper part of the fixed bracket.

[0013] It also includes an umbrella fabric, which is disposed on a plurality of umbrella rib assemblies.

[0014] It also includes a control circuit board, which is used to control the drive unit.

Therefore, they should not be construed as limitations on this utility model.

[0026] Combined with appendix Figures 1 to 5As shown, this embodiment discloses a sunshade with an electric opening structure, including several umbrella rib components 1, umbrella columns 5, a base 6, and an opening mechanism 2. The opening mechanism 2 is located at the top of the umbrella columns 5. The opening mechanism 2 includes a drive component 21, several transmission components 22, and several fixed supports 23. The transmission components 22 are located inside the fixed supports 23. The drive component 21 includes a drive part 211, a lead screw 212, and a lifting platform. The drive part 21 drives the lead screw 212 to rotate. The lifting platform cooperates with the lead screw 212 and moves up and down as the lead screw 212 rotates. The lifting platform includes a lead screw nut 213 and a lifting seat body 214. The lead screw nut 213 is installed inside the lifting seat body 214 and is used to cooperate with the lead screw 212.

[0027] In conjunction with the above, the drive unit 211 is connected to the lower end of the lead screw 212. In this embodiment, the drive unit 211 is a drive motor, which is installed in the upper inner cavity of the umbrella column 5. The rotating shaft of the drive motor is connected to the lower end of the lead screw 212. The lead screw nut 213 is sleeved on the outside of the lead screw 212, and there are matching threads between the lead screw 212 and the lead screw nut 213. The lifting seat body 214 is sleeved on the outside of the lead screw nut 213. The drive unit 211 causes the lead screw 212 to rotate, thereby driving the lead screw nut 213. The lifting seat body 214 moves up and down on the lead screw 212; the transmission component 22 includes a linkage arm 221, a first driven part 222 and a second driven part 223. The second driven part 223 is connected to the umbrella rib assembly 1. The linkage arm 221 is connected to the lifting seat body 214, the first driven part 222, the second driven part 223 and the fixed bracket 23 in cooperation. As the lifting seat body 214 moves up and down, it drives the second driven part 223 and the umbrella rib assembly 1 to move, thereby realizing the opening and closing of the umbrella rib assembly 1.

[0028] Based on the above installation structure, the linkage arm 221 includes a first linkage part 2211, a second linkage part 2212, a third linkage part 2213, and a fourth linkage part 2214. The lifting seat body 214 has several connecting grooves 2141 evenly arranged in the circumferential direction. The first linkage part 2211 is disposed within the connecting groove 2141 and hingedly connected to the lifting seat body 214. After hinged connection, the first linkage part 2211 can swing within the connecting groove 2141. The second linkage part 2212 is hingedly connected to the upper end of the first driven part 222. The second driven part 223 includes a gear part, and the third linkage part 2213 is provided with several teeth. The gear parts and teeth match each other, and the third linkage part 2213 meshes with the second driven part 223. The fourth linkage part 2214 is hingedly connected to the middle of the fixed bracket 23, which can improve the stability of the linkage arm 221 during transmission.

[0029] In conjunction with the above installation structure, the lower part of the fixed bracket 23 is provided with a sliding groove 231, and a sliding member 232 is provided in the sliding groove 231. The sliding member 232 cooperates with the sliding groove 231, and the sliding member 232 can slide along the direction of the sliding groove 231. The lower end of the first driven part 222 is hinged to the sliding member 232.

[0030] Based on the above installation structure, the opening process of this utility model is as follows: When the sun umbrella changes from the closed state to the unfolded state, the drive unit 211 drives the lead screw 212 to rotate, causing the lead screw nut 213 and the lifting seat body 214 sleeved on the lead screw nut 213 to move upward on the lead screw 212. The lifting seat body 214 drives one end of the first linkage part 2211 to move upward, causing the entire linkage arm 221 to deflect. The linkage arm 221 rotates around the fourth linkage part 2214 as the axis, causing the third linkage part 2213 to rotate. The third linkage part 2213 meshes with the second driven part 223, causing the second driven part 223 to rotate, thereby causing the umbrella rib assembly 1 to unfold upward, realizing the unfolding of the entire umbrella frame.

[0031] When the umbrella is unfolded and then closed, the drive unit 211 rotates in the opposite direction, driving the lead screw 212 to rotate. This causes the lead screw nut 213 and the lifting seat body 214 sleeved on the lead screw nut 213 to move downwards on the lead screw 212. The lifting seat body 214 drives one end of the first linkage unit 2211 to move downwards, causing the entire linkage arm 221 to deflect. The linkage arm 221 rotates around the fourth linkage unit 2214 as the axis, driving the third linkage unit 2213 to rotate. The third linkage unit 2213 meshes with the second driven unit 223, causing the second driven unit 223 to rotate, thereby driving the umbrella rib assembly 1 to close downwards, realizing the closure of the entire umbrella frame.

[0032] In conjunction with the above, when the umbrella is opened, the height of the second linkage part 2212 rises, which in turn raises the height of the first driven part 222, causing the lower end of the first driven part 222 to drive the slider 232 to slide upward, and an angle is formed between the second linkage part 2212 and the first driven part 222.

[0033] In summary, the umbrella opening mechanism 2 has an optimized design for the umbrella rib buffer assembly, which can provide a buffering effect for each component of the umbrella opening mechanism 2 when it encounters external forces while the sun umbrella is in the open state.

[0034] In conjunction with the above, the umbrella rib buffer assembly includes several buffer springs 24. Each buffer spring 24 is disposed on one side of a single fixed bracket 23. The upper end of the buffer spring 24 is fitted with the upper spring seat 241 on the upper part of the fixed bracket 23, and the lower end is fitted with the lower spring seat 242 on the sliding member 232.

[0035] Combined with the above installation structure, when the sliding member 232 moves upward, the buffer spring 24 relaxes. If the present invention is in the open state in an environment such as strong wind, the external forces such as wind and rain will cause the umbrella rib assembly 1 to tend to close, the buffer spring 24 will tighten, causing the transmission assembly 22 to undergo transmission deformation. The transmission assembly 22 drives the sliding member 232 to move downward along the sliding groove 231, thereby providing buffer for the umbrella opening part 2. After the external force disappears, the buffer spring 24 will reset.

[0036] Combined with the above installation structure, the buffer spring 24 can protect the components of the umbrella opening section 2, preventing the components of the umbrella opening section 2 from generating large stresses due to the need to keep them fixed when external forces are applied, thereby improving the structural stability and strength of the sun umbrella and extending its service life.

[0037] In conjunction with the above, the umbrella rib assembly 1 includes an umbrella rib connecting part 11, and a second driven part 223 is disposed in the umbrella rib connecting part 11 and is hinged to the upper part of the fixed bracket 23.

[0038] In conjunction with the above, it also includes a control circuit board 3 and a solar panel 4. The control circuit board 3 is used to receive signals and control the drive unit 211. The solar panel 4 includes a battery. The solar panel 4 is located at the top of the sunshade and is usually located in the center position. The control circuit board 3 is located above the umbrella opening mechanism 2. The solar panel 4 is connected to the control circuit board 3. The solar panel 4 can convert solar energy into electrical energy and store the electrical energy in the battery to provide power to the control circuit board 3 and the drive unit 211. The structure and principle of the control circuit board 3 and the solar panel 4 adopt common and universal technologies in the prior art.

[0039] In addition to the above, the present invention also includes an umbrella fabric, which is disposed on a plurality of umbrella rib assemblies 1 for the purpose of shielding from wind and rain.

[0040] In summary, the parasol can be either a center-pillar umbrella or a Roman umbrella, and can be used for various outdoor parasol structures, making it highly practical and versatile.

[0041] This invention optimizes the umbrella ribs and opening structure, eliminating the need for short ribs and improving the overall aesthetics and structural strength of the sun umbrella. It also features an electric opening design, making the opening process more convenient and effortless. Furthermore, the addition of a rib buffer component provides cushioning protection for all parts of the opening mechanism, extending the lifespan of the sun umbrella.

[0042] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
