Description

Technical Field

[0001] This utility model relates to the field of outdoor umbrella technology, specifically to an automatic opening and closing outdoor sunshade umbrella. Background Technology

[0002] Outdoor sun umbrellas are common sun-shading devices widely used in open environments such as commercial streets, landscaped gardens, restaurant terraces, and leisure courtyards. They are mainly used to provide people with sun protection, rain protection, and UV protection. Existing outdoor sun umbrellas typically include a support pole, an umbrella canopy, a rib structure that supports the canopy, and an opening and closing mechanism for opening or closing the canopy.

[0003] However, due to the unpredictable wind interference in outdoor environments, existing sun umbrellas generally lack sufficient wind resistance. Most existing sun umbrellas use a foldable rib structure. On the one hand, when the canopy is open, it creates a large windward surface, making it susceptible to wind impact, which can cause it to tip over, shift, or even break the ribs. On the other hand, the canopy's height when open makes it more vulnerable to wind, increasing the likelihood of swaying and structural instability at the top.

[0004] In actual use, in order to avoid damage to the sun umbrella by wind, users often need to close the umbrella or move the position of the sun umbrella when the wind is strong. The manual operation is quite burdensome. Especially when used in a large area, if a strong wind suddenly blows, the umbrella often cannot be closed in time, which may cause the sun umbrella to be overturned or blown away, affecting the safety of people and surrounding property.

[0005] Therefore, it is necessary to research an automatic opening and closing outdoor sunshade. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide an automatic opening and closing outdoor sunshade that can effectively solve the problem that existing outdoor sunshades require frequent manual opening and closing to cope with strong winds.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An automatic opening and closing outdoor sunshade includes a hanger, a canopy, a canopy opening and closing mechanism, and a wind gauge;

[0009] The hanger is set vertically, with its bottom fixed to the ground and its side horizontally fixed with a mounting platform. The mounting platform has a through clearance hole.

[0010] The umbrella opening and closing mechanism includes a screw sleeve, a screw rod, and a motor;

[0011] The screw sleeve is rotatably mounted on the mounting platform, the motor is fixed on the mounting platform, and the screw sleeve is connected to the output shaft of the motor for transmission.

[0012] The screw passes vertically through the clearance hole through the mounting platform and is threadedly connected to the screw sleeve.

[0013] The umbrella body includes upper ribs, lower ribs, and umbrella canopy;

[0014] The upper and lower umbrella ribs are arranged in multiple sets corresponding to each other on the circumference. The end of the upper umbrella rib is hinged to the lower surface of the mounting platform. The umbrella canopy is set on the upper umbrella rib.

[0015] One end of the lower umbrella rib is hinged to the lower end of the screw, and the other end of the lower umbrella rib is hinged to the middle of the upper umbrella rib.

[0016] The wind turbine is mounted on top of the screw, and both the wind turbine and the motor are connected to the controller.

[0017] As the screw moves downwards, the umbrella gradually closes and the anemometer moves downwards accordingly.

[0018] Furthermore, a mounting base is fixedly connected to the upper surface of the mounting platform. The mounting base has an upper-opening mounting cavity, and the lower part of the threaded sleeve is rotatably disposed in the mounting cavity via a bearing.

[0019] Furthermore, the upper part of the screw sleeve and the output shaft of the motor are both fixedly fitted with synchronous pulleys and connected by synchronous belt drive.

[0020] Furthermore, an annular hinge plate is fixed to the lower surface of the mounting platform, and multiple hinge seats that are hinged to the upper umbrella ribs are evenly arranged around the lower circumference of the hinge plate.

[0021] Furthermore, a hinge ring is fixedly sleeved at the lower end of the screw, and multiple hinge joints that are hinged to the lower umbrella ribs are evenly arranged on the side wall circumference of the hinge ring.

[0022] Furthermore, a protective cover is installed on the mounting platform, and the screw sleeve and motor are both located inside the protective cover; a through hole is provided on the top of the protective cover for the screw to pass through.

[0023] Furthermore, a canopy is installed between the screw and the anemometer. When the screw moves downwards until the umbrella body is fully retracted, the canopy covers the protective cover and conceals the through hole.

[0024] The beneficial effects of the above technical solution are:

[0025] The utility model enables the screw rod to move up and down by setting a screw sleeve - screw rod structure driven by a motor, and cooperates with the connecting rod mechanism formed by the upper umbrella ribs and the lower umbrella ribs, so that the umbrella body can automatically complete the opening and closing actions under the drive of the motor. A wind gauge is arranged at the top of the screw rod, which can rise synchronously with the screw rod to an unobstructed position when the umbrella body is opened, realizing accurate monitoring of the wind speed, and联动 with the controller to judge whether the umbrella - closing condition is met. When the wind force is too large, the controller can automatically start the motor to lower the screw rod, quickly complete the closing of the umbrella body, improve the safety and automatic response ability of the umbrella body in bad weather, solve the problem that the existing outdoor sunshade umbrella needs to be frequently opened and closed manually to cope with strong winds, greatly reduce the manual operation frequency, reduce the damage risk of the sunshade umbrella caused by strong winds, and significantly improve the intelligent level and wind - resistance safety of the sunshade umbrella in the outdoor environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following further describes the present utility model in detail with reference to the drawings and specific embodiments:

[0030] This embodiment aims to provide an automatically opening and closing outdoor sunshade umbrella to solve the problem that the existing outdoor sunshade umbrella needs to be frequently opened and closed manually to cope with strong winds.

[0031] An automatically opening and closing outdoor sunshade umbrella, as shown in Figure 1 and 2 , includes a hanging bracket 1, an umbrella body, an umbrella - surface opening and closing mechanism, and a wind gauge 9. The hanging bracket 1 is vertically arranged on the ground. The hanging bracket 1 includes a column 101 and a connecting frame 102. The bottom of the column 101 is fixed to the ground, and the connecting frame 102 is fixedly installed on the side of the top of the column 101. An installation table 5 is horizontally and fixedly installed on the side of the hanging bracket 1, and the installation table 5 is fixedly connected with the connecting frame 102. An avoidance hole 501 that penetrates up and down is opened on the installation table 5 for avoiding the screw rod 3.

[0032] The umbrella opening and closing mechanism includes a screw sleeve 2, a screw rod 3, and a motor 4. The screw sleeve 2 is rotatably mounted on the mounting platform 5. Specifically, a mounting seat 10 is fixedly connected to the upper surface of the mounting platform 5. The mounting seat 10 has an upper open mounting cavity. The bottom of the mounting cavity is also provided with a through hole for avoiding the screw rod 3. The lower part of the screw sleeve 2 is rotatably mounted in the mounting cavity through a bearing 19.

[0033] The motor 4 is fixed on the upper surface of the mounting platform 5. The screw sleeve 2 is connected to the output shaft of the motor 4. Specifically, the upper part of the screw sleeve 2 and the output shaft of the motor 4 are both fixedly fitted with synchronous pulleys 11 and connected by synchronous belts 12, so that the motor 4 can drive the screw sleeve 2 to rotate.

[0034] The screw 3 passes vertically through the clearance hole 501 through the mounting platform 5 and is threadedly connected to the screw sleeve 2, so that the screw 3 can move up and down under the drive of the screw sleeve 2.

[0035] The umbrella body includes an upper umbrella rib 6, a lower umbrella rib 7, and an umbrella canopy 8. The upper umbrella rib 6 and the lower umbrella rib 7 are arranged in eight sets around the circumference, forming an umbrella rib structure. The end of the upper umbrella rib 6 is hinged to the lower surface of the mounting platform 5. Specifically, an annular hinge plate 13 is fixed to the lower surface of the mounting platform 5, and eight hinge seats 14 that are hinged to the upper umbrella rib 6 are evenly fixed to the lower circumference of the hinge plate 13.

[0036] The canopy 8 is laid on the upper umbrella ribs 6 to form the umbrella body. The specific laying and binding process and the selection of materials are all existing technologies, and will not be described in detail here.

[0037] One end of the lower umbrella rib 7 is hinged to the lower end of the screw 3. A hinge ring 15 is fixedly fitted onto the lower end of the screw 3. Eight hinge joints 16, which are evenly arranged around the sidewall of the hinge ring 15 and hinged to the lower umbrella rib 7, are also present. Simultaneously, the lower umbrella rib 7 restricts the rotation of the screw 3, ensuring that the screw 3 can move up and down under the drive of the screw sleeve 2. The other end of the lower umbrella rib 7 is hinged to the middle of the upper umbrella rib 6, so that when the screw 3 moves downwards, the umbrella gradually closes, and when the screw 3 moves upwards, the umbrella gradually opens. The direction of movement of the screw 3 is controlled by the rotation direction of the output shaft of the motor 4. The speed and direction of the motor 4 are both controlled by the controller.

[0038] Anemometer 9 is mounted on top of screw 3 and rises and falls with screw 3. When the umbrella is open, anemometer 9 is positioned at its highest point to detect wind force. Both anemometer 9 and motor 4 are connected to a controller to detect current wind force data. When the wind force exceeds a threshold, the controller controls motor 4 to rotate, causing the umbrella to close. The controller can be a 32-bit microcontroller and can be directly mounted on mounting platform 5 or connected via cable to be placed on the ground. Power supply for the controller, motor 4, and anemometer 9 can be achieved by connecting cables to the ground; these are existing technologies and will not be elaborated upon here.

[0039] Furthermore, a protective cover 17 is installed on the mounting platform 5 to protect the equipment above. The screw sleeve 2 and the motor 4 are both located inside the protective cover 17. A through hole 1601 is provided on the top of the protective cover 17 for the screw 3 to pass through.

[0040] Furthermore, such as Figure 2 A canopy 18 is installed between the screw 3 and the anemometer 9. When the screw 3 moves downward until the umbrella body is fully retracted, the canopy 18 covers the protective cover 17 and covers the through hole 1601 to prevent wind and sand from entering the screw sleeve 2 and the synchronous belt mechanism through the through hole 1601 and causing damage.
