Description

Technical Field

[0001] This utility model relates to the field of sunshades, and in particular to an outdoor foldable sunshade. Background Technology

[0002] The lack of sunshades in outdoor parking lots, especially in summer, can accelerate the aging of car parts due to prolonged exposure to sunlight. Existing outdoor sunshade structures consist of a sunshade canopy and several supporting columns. Once installed, the sunshade canopy cannot be folded or extended, making it easily overturned in strong winds and causing damage. Utility Model Content

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

[0030] See Figure 1 This utility model proposes an outdoor foldable sunshade, including a central column 1 fixed on the ground. The top of the central column 1 is provided with a liftable control rod 11. An electric push rod can be installed on the top of the central column 1 to achieve the lifting effect of the control rod 11.

[0031] Several sunshade components 2, see Figure 2 , 7The sunshade assembly 2 includes a fixed base 21 and a linkage rod 22. The fixed base 21 is fixed to the peripheral side of the central column 1. The sunshade assembly 2 has four sets. A control block 23 is slidably connected to the fixed base 21. A lifting assembly 24 is provided between the fixed base 21 and the control block 23. The lifting assembly 24 is used to drive the control block 23 to move up and down. An extension rod 25 is rotatably connected to the control block 23. A linkage ring 251 is slidably connected to the extension rod 25. The two ends of the linkage rod 22 are hinged to the fixed base 21 and the linkage ring 251, respectively. A foldable sunshade umbrella 26 is rotatably connected to the outer end of the extension rod 25. Figure 7 As shown, when the control block 23 moves upward, the extension rod 25 extends outward until it is completely horizontal. Then, the sunshade umbrella 26 rotates vertically via the rotating assembly 27 between it and the extension rod 25 until it is completely vertical. After all the sunshade components 2 are in place, each sunshade umbrella 26 unfolds, achieving the desired effect. Figure 8 The sunshade state shown, the specific structure of the sunshade umbrella 26 can be referred to Chinese patent CN206171151U, which will not be described in detail in this application;

[0032] A protective cover 3 is also provided above the central column 1. The protective cover 3 is fixed to the top of the control rod 11. The protective cover 3 has a protective cavity inside. (See reference...) Figure 1 The protective cavity is used to accommodate the sunshade assembly 2. Before the sunshade assembly 2 is deployed, the protective cover 3 needs to move upward to prevent interference between the two.

[0033] Users can control the extension and retraction of the sunshade component 2 according to changes in the usage environment to reduce the wind-exposed area, and the protective cover 3 provides protection for the sunshade component 2 in the stored state, reducing the chance of damage to the sunshade caused by harsh environments.

[0034] Referring to 3 and 5, the fixed base 21 has a sliding cavity 211, and the side of the sliding cavity 211 has a sliding groove 212. The control block 23 slides in the sliding groove 212. The lifting assembly 24 includes a lead screw 241, a lifting motor 242, and a lead screw nut 243. The lead screw 241 is rotatably connected to the sliding cavity 211. The lifting motor 242 is fixedly connected to the fixed base 21 and is used to drive the lead screw 241 to rotate. The lead screw nut 243 is sleeved on the lead screw 241. The control block 23 is fixedly connected to the lead screw nut 243. In this embodiment, the control block 23 has a through hole in the middle, and the lead screw nut 243 is fixed in the through hole. The vertical movement of the control block 23 is achieved by the transmission of the lead screw 241. In other embodiments, a linear slide rail can also be provided on the fixed base 21, and the control block 23 is set on the linear slide rail to achieve vertical sliding.

[0035] See Figure 4 The rotating assembly 27 includes a rotating base 271, which is fixedly connected to the extension rod 25. A support plate 272 is fixed on the rotating base 271. A rotating motor 273 and several linkage gears 274 are provided on the support plate 272. A rotating shaft 261 is fixed to the end of the sunshade 26. The rotating shaft 261 is rotatably connected to the support plate 272. To ensure the stability of the rotating shaft 261, an auxiliary plate can be provided on the side of the support plate 272. A driven gear 262 is fixed on the rotating shaft 261. The driven gear 262 meshes with the linkage gears 274. The rotating motor 273 drives the linkage gears 274 to rotate, which in turn drives the rotation of the sunshade 26 via the driven gears 262, thereby adjusting the position of the sunshade 26.

[0036] See Figure 3 , 4 A dust cover 275 is fixed on the rotating base 271. The dust cover 275 can reduce the contact between external dust and the internal rotating component 27, and extend the service life of the rotating component 27. The dust cover 275 is provided with a clearance slot 276. The rotating shaft 261 is located below the clearance slot 276, and the sun umbrella 26 rotates in the clearance slot 276.

[0037] See Figure 6 The control block 23 is provided with several rollers 231 below it. Preferably, two sets of rollers 231 are symmetrically arranged and located on both sides of the control block 23. Two guide rods 213 are provided at intervals at the bottom of the sliding cavity 211. The inner side of the guide rod 213 is provided with a guide groove 214. The rollers 231 slide in the guide groove 214. The control block 23 can slide up and down through the cooperation of the rollers 231 and the guide groove 214, and also has the effects of preventing slippage and guiding.

[0038] To enhance the product's intelligence, the top of the protective cover 3 is equipped with an anemometer and a light sensor. Through an external intelligent control device, it identifies signals of changes in wind speed and light, and autonomously recognizes changes in the external environment and controls the opening and closing of the sunshade even without human intervention. The intelligent control device can be directly controlled in the same circuit as the lifting assembly 24, the rotating assembly 27, and the electric push rod, or it can control these components via Bluetooth signals or other means.

[0039] See Figure 3 , 5The extension rod 25 has a hollow structure, and an adjusting rod 252 is slidably connected inside the extension rod 25. A lead screw assembly 253 is provided between the extension rod 25 and the adjusting rod 252. The specific structure of the lead screw assembly 253 can be referred to the lifting assembly 24, and the two are based on the same principle. The sun umbrella 26 is fixed to the end of the adjusting rod 252. The extension and retraction of the adjusting rod 252 can be controlled by the lead screw assembly 253 to adapt to the usage needs of sun umbrellas 26 with different unfolded areas.

[0040] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
