[0023] Electric sunshades are mostly used in parks, scenic areas, and densely populated commercial streets, squares, and other open-air places, providing shade and shelter from rain when the sun is too strong or it is raining. Landscape sunshades are relatively large and usually need to be fixed in one place, but in many situations they need to be closed, such as in extreme weather to prevent further damage, or on rainless nights when the umbrella may obstruct people's view, making it necessary to completely close the umbrella.

[0024] The existing straight-arm electric sunshade has a one-piece main column structure, and the weight of a single electric sunshade is relatively large (the main structure is all steel, so the weight of the smallest model of umbrella exceeds 850 kg). In addition, the irregular shape of the main structure of the umbrella requires larger vehicles and lifting equipment for transportation and installation, which increases the overall cost and reduces installation efficiency.

[0025] To solve the above problems, please refer to... Figures 1 to 3 This utility model proposes a straight-arm electric sunshade 100, including a base 1, a support rod 2 and an umbrella body 3. The support rod 2 is connected to the base 1. The umbrella body 3 includes a telescopic rod 31, an umbrella rib assembly 32 and an umbrella surface 33. The umbrella surface 33 is connected to the umbrella rib assembly 32. The umbrella rib assembly 32 can be opened and closed by telescopically extending and retracting the telescopic rod 31. The telescopic rod 31 is detachably connected to the end of the support rod 2 away from the base 1.

[0026] This utility model proposes a straight-arm electric sunshade 100, suitable for courtyards, terraces, outdoor cafes, scenic area rest areas, and other scenarios. The opening, closing, and position adjustment of the canopy 33 are achieved through electric control, providing users with a stable shaded space. The sunshade mainly consists of a base 1, a support rod 2, and an umbrella body 3. The base 1 is made of cast iron and has an overall disc-shaped or square structure. Its weight is determined according to the overall size of the sunshade to ensure sufficient counterweight and prevent it from tipping over due to wind during outdoor use. A screw hole is located at the center of the upper surface of the base 1 for connection to the support rod 2. The support rod 2 is made of aluminum alloy or stainless steel and has a tubular structure, providing high strength and corrosion resistance. Its lower end is connected to the screw hole of the base 1 via bolts, standing vertically on the ground to provide vertical support for the umbrella body 3. Its length is designed according to the required shade height. The telescopic rod 31 of the umbrella body 3 is made of lightweight alloy tubing with good rigidity. Its lower end is detachably connected to the end of the support rod 2 away from the base 1 via a snap-fit ​​or threaded structure, facilitating disassembly during transportation and storage. The umbrella rib assembly 32 consists of multiple supporting ribs 321, made of fiberglass or aluminum alloy, possessing both toughness and strength. One end is evenly hinged to the top of the telescopic pole 31, while the other end extends outward to support the umbrella canopy 33. The umbrella canopy 33 is made of polyester or Oxford cloth, coated with an anti-UV and waterproof coating, and is fixed to the supporting ribs 321 of the umbrella rib assembly 32 by stitching. When unfolded, it forms a circular or square sunshade area, the area of ​​which is determined by the length of the supporting ribs 321. When the telescopic pole 31 extends or retracts, it causes the umbrella rib assembly 32 to rotate around the hinge point, thus opening and closing the umbrella canopy 33. The detachable connection between the telescopic pole 31 and the supporting pole 2 allows users to easily remove and store the umbrella body 3 when not in use, reducing space occupation and facilitating the individual replacement of damaged parts, thus reducing maintenance costs. Through this structural design, the sun umbrella not only meets the needs of stable outdoor sunshade but also has convenient disassembly, assembly, and maintenance characteristics, making it suitable for various outdoor usage scenarios.

[0027] Furthermore, in one embodiment, the umbrella body 3 further includes a driving member 4, and the telescopic rod 31 includes a first sleeve 311 and a second sleeve 312. The second sleeve 312 is sleeved on the outside of the first sleeve 311, and the second sleeve 312 and the inner cavity of the support rod 2 enclose each other to form an installation cavity. The driving member 4 is disposed in the installation cavity, and the output end of the driving member 4 is connected to the first sleeve 311 to drive the first sleeve 311 to move up and down along the support rod 2.

[0028] The drive component 4 uses a linear actuator motor, which is compact and provides stable thrust. Its fixed end is fixed to the inner wall of the support rod 2 with bolts. The first sleeve 311 of the telescopic rod 31 is a hollow metal tube with a smooth inner wall. Its lower end is connected to the output end of the drive component 4 and can move axially along with the output end of the drive component 4. The second sleeve 312 is also a hollow metal tube with an inner diameter slightly larger than the outer diameter of the first sleeve 311. It is fitted on the outside of the first sleeve 311. The lower end of the second sleeve 312 is connected to the upper end of the support rod 2. The inner cavities of the two are interconnected, forming a closed mounting cavity. The drive component 4 is completely placed inside the mounting cavity, preventing outdoor rainwater and dust from entering the drive component 4 and causing damage. When the drive unit 4 is activated, its output end pushes the first sleeve 311 upward along the axial direction of the support rod 2. The first sleeve 311 drives the umbrella rib assembly 32 to extend upward, thereby opening the umbrella surface 33. When the drive unit 4 runs in the reverse direction, its output end pulls the first sleeve 311 downward. Under the action of its own weight and the tension of the umbrella surface 33, the umbrella rib assembly 32 retracts, thereby closing the umbrella surface 33. The closed structure of the mounting cavity protects the drive unit 4 from outdoor environmental corrosion, extending its service life. The linear push rod motor ensures that the extension and retraction of the telescopic rod 31 is smooth, and the opening and closing speed of the umbrella surface 33 is uniform, avoiding damage to the umbrella ribs caused by manual operation and improving ease of use and safety.

[0029] In one embodiment, the umbrella rib assembly 32 includes a plurality of support ribs 321 and a plurality of connecting rods 322. Each support rib 321 is hinged to the outer peripheral wall of the second sleeve 312. Each end of the connection along the length direction is respectively hinged to the first sleeve 311 and a support rib 321. The umbrella surface 33 is connected to the side of the support rib 321 facing away from the connecting rod 322.

[0030] The supporting ribs 321 are made of fiberglass, which has good bending resistance. The number of ribs is determined according to the size of the umbrella canopy 33, usually 6-12. One end of each supporting rib 321 is evenly hinged to the outer peripheral wall of the second sleeve 312, allowing the supporting rib 321 to rotate outward or inward around the hinge. The connecting rods 322 are made of lightweight metal rods, with a length adapted to the length of the supporting ribs 321. The two ends of each connecting rod 322 are respectively connected by hinges to the outer peripheral wall of the first sleeve 311 and the middle position of a supporting rib 321, forming a triangular support structure. The edge of the umbrella canopy 33 is fixed to the side of the supporting rib 321 away from the connecting rod 322 by stitching, that is, the side of the supporting rib 321 away from the center of the telescopic rod 31, ensuring that the umbrella canopy 33 can be stably supported by the supporting ribs 321 when it is opened. When the driving component 4 pushes the first sleeve 311 upward, the first sleeve 311 drives the middle part of the support rib 321 upward through the connecting rod 322. The support rib 321 rotates outward around the hinge point with the second sleeve 312, gradually unfolding and supporting the umbrella surface 33. When the first sleeve 311 moves downward, the connecting rod 322 pulls the middle part of the support rib 321 downward, the support rib 321 rotates inward, and the umbrella surface 33 closes accordingly. The triangular support structure makes the umbrella rib assembly 32 more stable under force, preventing the support rib 321 from deforming under outdoor wind. At the same time, the transmission action of the connecting rod 322 ensures that each support rib 321 opens and closes synchronously. After the umbrella surface 33 is unfolded, it has high flatness and uniform sunshade effect, further improving the reliability of the sun umbrella for outdoor use.

[0031] In one embodiment, the straight-arm electric sunshade 100 further includes a water collection tank 5, which is arranged around the outer peripheral wall of the second sleeve 312 and faces the inner edge of the umbrella surface 33.

[0032] The water collection trough 5 is made of plastic or aluminum alloy and is formed by injection molding or stamping. It has a ring-shaped structure, and its inner diameter matches the outer diameter of the second sleeve 312. It is fixed to the outer wall of the second sleeve 312 by clips or glue. The installation position is below the hinge point of the umbrella rib assembly 32 and facing the inner edge of the umbrella surface 33, meaning the opening of the water collection trough 5 faces upwards, ensuring that rainwater dripping from the umbrella surface 33 can flow smoothly into the water collection trough 5. One or two drain outlets can be installed at the bottom of the water collection trough 5, and these outlets are connected to the ground or a rainwater collection device via flexible hoses. When it rains outdoors, rainwater on the surface of the umbrella 33 will converge towards the center along the tilt direction of the umbrella 33 and eventually drip into the water collection tank 5, and then be discharged through the drain outlet and hose. This prevents rainwater from dripping directly from the connection between the umbrella body 3 and the support rod 2 onto the user below or ground facilities, improving the comfort of use in rainy weather. At the same time, it prevents rainwater from flowing into the interior along the support rod 2 and damaging the drive component 4 or other electrical components, extending the overall service life of the sun umbrella and making it suitable for rainy outdoor environments.

[0033] In one embodiment, the support rod 2 and the second sleeve 312 are connected by a flange. A circular flange is welded to the upper end face of the support rod 2, and 4-6 bolt holes are evenly machined along the circumference of the flange. Similarly, a flange matching the flange of the support rod 2 is welded to the lower end face of the second sleeve 312, with the same number of through holes at corresponding positions. During connection, the end faces of the two flanges are brought together, aligning the bolt holes with the through holes. Bolts are then passed through the through holes and screwed into the bolt holes, and the nuts are tightened to achieve a fixed connection. The flange connection ensures the connection strength between the support rod 2 and the second sleeve 312, preventing them from separating due to vibration or wind during outdoor use. Simultaneously, the sealing surface of the flange can be enhanced with rubber gaskets to prevent rainwater from seeping into the installation cavity through the connection gaps. When disassembly or maintenance is required, only the bolts need to be removed to separate the support rod 2 and the second sleeve 312, making operation convenient and balancing connection stability and maintenance convenience, thus meeting the structural strength requirements for long-term outdoor use.

[0034] In one embodiment, the support rod 2 has a hollow tubular structure, made of seamless aluminum alloy tubing. The wall thickness is determined according to the support requirements, ensuring sufficient structural strength to support the weight of the umbrella body 3 while reducing the overall weight of the support rod 2, facilitating transportation and installation. The hollow cavity can accommodate the power cord, control cord, and wiring for subsequent functional modules of the drive component 4, preventing the wiring from being exposed to the elements and aging or damaging due to sun and rain. It also makes the sunshade umbrella look cleaner and reduces the impact of external wiring on the aesthetics of the usage scenario. Furthermore, the hollow cavity also reserves space for future functional expansion, such as adding sensors and control modules, improving the sunshade umbrella's intelligence level, adapting to different users' needs for functional upgrades, and enhancing the product's practicality and competitiveness.

[0035] In another embodiment, the support rod 2 is further provided with a control module and a function module, and the control module is electrically connected to the function module to control the operation of the function module.

[0036] The control module, which can be a microcontroller or PLC controller, is fixed to the hollow cavity of the support rod 2 via a bracket. Its input end connects to an external power supply and a wireless receiver module, receiving control commands from a remote control. The output end is electrically connected to the drive unit 4 and the functional module via wires, controlling their operation. The functional module is bolted to a preset position within the cavity or on the outer wall of the support rod 2, maintaining an electrical connection with the control module and implementing specific functions according to user needs. The control module provides the sunshade with a central hub for electric control, allowing users to remotely control the opening and closing of the umbrella 3 without manual operation. The addition of the functional module expands the sunshade's usage scenarios, such as providing cooling in hot weather or audio playback in leisure settings, enhancing the user experience and transforming the sunshade from a simple sunshade device into a multifunctional outdoor leisure aid.

[0037] In one embodiment, the functional module includes one or more of a speaker, a cooler, and a sprayer. The speaker can be a waterproof Bluetooth speaker, fixed to the middle of the outer wall of the support rod 2 via a bracket, and electrically connected to the control module. It can receive commands from the control module to play music, and its waterproof design ensures normal use in rainy weather, creating an atmosphere for outdoor leisure scenarios. The cooler can be a small evaporative cooler, installed on the upper part of the support rod 2, with the air outlet facing the sunshade area below the umbrella surface 33. It is electrically connected to the control module, and when turned on, it delivers cool air to the user's activity area, lowering the ambient temperature and adapting to the hot summer outdoor environment. The sprayer can be a high-pressure micro-mist sprayer, with the nozzle installed on the support rib 321 of the umbrella rib assembly 32. It is connected to a water pump inside the support rod 2 via a water pipe, and the water pump is electrically connected to the control module. When turned on, the nozzle sprays a fine mist, using water evaporation to remove heat and achieve cooling. Users can select single or combined functional modules according to their usage scenarios. The control module enables independent control of each functional module via remote control, meeting the usage needs of different scenarios and improving the versatility and adaptability of the sun umbrella.

[0038] In one embodiment, the support rod is also equipped with a display screen, which is electrically connected to the control module.

[0039] The display screen is a waterproof touchscreen, fixed to the middle of the outer wall of the support rod 2 by a bracket for easy user operation and viewing. The display screen is electrically connected to the control module via wires, and can display the real-time working status of the sunshade, such as the opening and closing degree of the umbrella surface 33, the operating status of functional modules, the current time, and weather information. Simultaneously, users can send commands to the control module via touch operation to control the opening and closing of the umbrella body 3 and adjust the parameters of functional modules, enabling local operation and compensating for the need to use the sunshade when the remote control is lost or the signal is poor. The display screen surface can be coated with an anti-glare coating to prevent unclear display due to direct sunlight; the outer shell adopts a waterproof structural design to prevent rainwater from seeping into the internal circuitry and ensuring stable use in complex outdoor environments. It provides users with an intuitive operating interface and information access channels, enhancing the product's intelligence and convenience.

[0040] In one embodiment, the base 1 has fixing holes, which are circular through holes. The number of fixing holes is determined according to the size of the base 1, usually 4-6, and they are evenly distributed along the circumference of the base 1. The included angle between adjacent fixing holes is equal to ensure that the base 1 is subjected to uniform force during fixing. Expansion bolts are used as the fixing components, and the specifications are selected according to the ground material. For example, M10-M12 expansion bolts with a length of 60-100mm are used for concrete ground, and M8-M10 expansion bolts with a length of 40-60mm are used for asphalt ground. During installation, the base 1 is placed in the preset position, aligning the fixing holes with pre-drilled holes in the ground. The expansion bolts are inserted through the fixing holes into the drilled holes, and the nuts of the expansion bolts are tightened, causing the expansion tubes to expand within the drilled holes and tightly engage with the ground, thus fixing the base 1 to the ground. This fixing method ensures that the base 1 will not shift under the action of outdoor wind, vibration, and other external forces, further improving the overall stability of the sunshade, avoiding the risk of tipping over, ensuring user safety, and adapting to the installation needs of various outdoor ground materials.
