Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a multi-axis rib cantilever umbrella, including...

[0031] The support mechanism 100 includes a support extension assembly 110; the umbrella body 200 includes a drive opening assembly 210, which includes a drive cylinder 211 fixedly installed at the end of the support extension assembly 110. A drive ring 215 is driven and sleeved at the bottom of the drive cylinder 211, and a fixed ring 216 is provided above the drive ring 215. Multiple sets of unfolding rings 217 are provided between the drive ring 215 and the fixed ring 216. An umbrella cloth 218 is connected between the drive ring 215, the fixed ring 216, and the unfolding rings 217. An auxiliary protection assembly 220 is provided in the middle of the drive opening assembly 210. The auxiliary protection assembly 220 is located between the drive ring 215 and the fixed ring 216. The drive ring 215 is driven to rotate by a motor 212, which drives the drive rod 219 to realize the rapid unfolding and retraction of the umbrella body 200. Compared with traditional manual operation, this greatly improves the convenience and efficiency of use.

[0032] Please see Figure 3 and Figure 4The support extension assembly 110 includes a base plate 111. A support rod 112 is threadedly connected to the top of the base plate 111. An extension rod 114 is connected to the top of the support rod 112. An installation cylinder 115 is fixedly connected to the end of the extension rod 114. A connecting cylinder 113 is fixedly connected to the top of the support rod 112. The connecting cylinder 113 is installed at an angle on the top of the support rod 112. The end of the extension rod 114 away from the installation cylinder 115 is inserted into the connecting cylinder 113. A bolt can be threaded through one side of the connecting cylinder 113. The position of the extension rod 114 can be limited by tightening the bolt. Other methods can also be used for limiting the position.

[0033] The top of the drive cylinder 211 is fixedly installed inside the mounting cylinder 115. A motor 212 is fixedly connected to the upper end of the drive cylinder 211, and a transmission rod 214 is fixedly connected to the output end of the motor 212. The bottom of the transmission rod 214 is fixedly connected to the inner wall of the drive ring 215. A plug-in rod is provided on one side of the drive ring 215, the fixing ring 216, and the unfolding ring 217. A drive rod 219 is plugged into each plug-in rod. Each pair of drive rods 219 is connected to the umbrella fabric 218 in sequence. The motor 212 drives the drive ring 215 to rotate, which drives the drive rods 219 to realize the rapid unfolding and retraction of the umbrella body 200. The drive rods 219 are connected through the drive ring 215, the fixing ring 216, and the unfolding ring 217, so there is a certain gap between each pair of drive rods 219, making the opening and folding process smoother. At the same time, the plug-in rods connected to the outer sides of the drive ring 215, the fixing ring 216, and the unfolding ring 217 are all inclined downwards.

[0034] A fixing ring 216 is fixedly sleeved on the drive cylinder 211, and an unfolding ring 217 is rotatably sleeved on the drive cylinder 211. The drive ring 215 is installed at the bottom of the drive cylinder 211 and is connected to the end of the transmission rod 214. A control box 213 is fixedly connected to the top of the drive cylinder 211. The control box 213 is frustum-shaped and contains a microcontroller to control the operation of the motor 212. The motor 212 can be configured as a servo motor, which can precisely control the rotation to avoid damaging the umbrella fabric 218. The umbrella fabric 218 is fan-shaped, and there is a certain gap between the umbrella fabric 218 and the drive cylinder 211. The control box 213 is located above the gap to compensate for it.

[0035] Please see Figure 4 and Figure 5The auxiliary protective component 220 includes a limiting plate 221, which is installed on the drive rod 219 outside the drive ring 215. A connecting frame 222 is vertically connected above the limiting plate 221, and a support plate 223 is fixedly connected to the top of the connecting frame 222. The support plate 223 is engaged with the drive rod 219 outside the fixed ring 216. The limiting plate 221 is C-shaped, and multiple fixing bolts 225 are evenly installed on its outer side. The fixing bolts 225 pass through the limiting plate 221 and are threaded to the outer side of the drive rod 219. The support plate 223 is U-shaped, rotated 90 degrees counterclockwise. The support plate 223 is inserted into and engaged with the drive rod 219 outside the fixed ring 216. A stop bar or other limiting device can be installed directly below the drive rod 219 outside the fixed ring 216 to prevent the other drive rods 219 from folding irregularly during folding.

[0036] A baffle 224 is provided between the limiting plate 221 and the support plate 223. The baffle 224 is located on one side of the connecting frame 222. Multiple sets of connecting frames 222 are equally distributed between the limiting plate 221 and the support plate 223. The baffle 224 can be made of mesh, waterproof cloth, sunshade cloth, etc.

[0037] Working principle: When the umbrella 200 needs to be deployed, the motor 212 is started. The transmission rod 214 at the output end of the motor 212 drives the drive ring 215 to rotate. The drive ring 215 is connected to the drive rod 219 through the plug rod on it, pulling multiple sets of drive rods 219 to expand radially around the drive cylinder 211. As the drive rods 219 move, the umbrella fabric 218 is gradually expanded, and finally the multiple sets of drive rods 219 and the umbrella fabric 218 form a conical surface. During this process, the limiting plate 221 of the auxiliary protective component 220 moves synchronously with the drive rods 219, and the support plate 223 gradually engages with both sides of the drive rods 219 outside the fixing ring 216, filling the height difference between the drive ring 215 and the fixing ring 216, playing a supporting and reinforcing role, and ensuring the stability of the umbrella 200 when deployed.

[0038] Retraction process: Motor 212 rotates in reverse, driving drive ring 215 to rotate. The support plate 223 of auxiliary protection component 220 pushes the drive rod 219 on the outside of fixed ring 216, causing the drive rods 219 on the outside of multiple sets of unfolding rings 217 to fold and retract synchronously. Limiting plate 221 is threadedly connected to drive rod 219 by fixing bolt 225, ensuring that the position of drive rod 219 is fixed during the retraction process, preventing the umbrella ribs from retracting irregularly, and finally the umbrella body 200 folds to a compact state.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
