DETAILED DESCRIPTION

[0017] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiment 1: A wind-resistant garden umbrella, such as Figure 1 , Figure 2 As shown, it includes a steering module, a wind receiving module and a control module; The steering module includes a base 1, a turntable 25, and a rotating motor 2. A motor cavity 3 is provided in the base 1. The rotating motor 2 is fixedly connected to the bottom surface of the motor cavity 3. A shaft seal 4 is inlaid on the top surface of the base 1. The output shaft of the rotating motor 2 is connected to the bottom surface of the turntable 25 through the shaft seal 4. The turntable 25 is coaxially arranged with the base 1. The wind receiving module comprises a column 5, a connecting rod 6, a support rod 7, an umbrella nest 8, an umbrella surface 9, and a plurality of umbrella ribs 10. The column 5 is vertically arranged on the top surface of the rotating disk 25. The top end of the column 5 is fixedly connected to one end of the connecting rod 6. The other end of the connecting rod 6 is located on the axis of the rotating disk 25. The top end of the support rod 7 is fixedly connected to the end of the connecting rod 6. The support rod 7 is coaxially arranged with the rotating disk 25. The umbrella nest 8 is sleeved on the support rod 7. A plurality of umbrella ribs 10 are rotatably connected to the side wall of the umbrella nest 8. The umbrella surface 9 is fixedly connected to the upper surface of the plurality of umbrella ribs 10. The length of the umbrella rib 10 located on the side of the support rod 7 away from the column 5 is greater than the length of the umbrella rib 10 located on the side of the support rod 7 close to the column 5. The control module includes a wind direction sensor 11 and a wind speed sensor 12 located at the top of the connecting rod 6 . The wind direction sensor 11 and the wind speed sensor 12 are both electrically connected to the rotating motor 2 .

[0019] Specifically, the base 1 is in the shape of a truncated cone, and four supporting legs are connected by bolts on the bottom surface of the base 1. The opening of the motor cavity 3 is covered with a top cover, and the top cover is connected to the base 1 by bolts. A circular hole is opened in the center of the top cover, and a shaft seal 4 is embedded in the circular hole. The bottom end of the column 5 is welded to the bottom surface of the turntable 25, and the column 5 and the connecting rod 6 are integrally formed. The connecting rod 6 is inclined upward, and the connecting rod 6 is connected to the supporting rod 7 by bolts. The length of the supporting rod 7 is less than the length of the column 5. The umbrella rib 10 includes a supporting bone and a supporting bone. One end of the supporting bone is rotatably connected to the top end of the supporting rod 7, and the other end of the supporting bone is fixedly connected to the edge of the umbrella surface 9. One end of the supporting bone is rotatably connected to the supporting bone, and the other end of the supporting bone is rotatably connected to the umbrella nest 8. In this embodiment, there are a total of eight umbrella ribs 10 on the umbrella nest 8, and the plane formed by the axis of the column 5 and the axis of the supporting rod 7 is used as the symmetry plane. The three umbrella ribs 10 on one side of the symmetry plane are symmetrical with the three umbrella ribs 10 on the other side. The umbrella rib 10 closest to the column 5 and the umbrella rib 10 closest to the column The farthest rib 10 from the column 5 is located on the symmetry plane, that is, the umbrella surface 9 forms an octagon with a symmetrical structure, the farthest rib 10 from the column 5 is the longest, and the lengths of the two adjacent ribs 10 are greater than those of the other five ribs 10, and the lengths of the other five ribs 10 are the same. When the wind blows toward the umbrella surface 9 along the direction from the column 5 to the support rod 7, the arched umbrella surface 9 is closer to a streamlined structure, which reduces the wind resistance of the umbrella surface 9. The wind speed sensor 12 is located above the wind direction sensor 11. The wind speed sensor 12 and the wind direction sensor 11 located above the umbrella surface 9 can make real-time feedback on the wind speed and wind direction, and use the corresponding signals to control the rotation of the rotating motor 2, so that the side of the umbrella surface 9 close to the column 5 is always used as the windward side, which reduces the wind force on the umbrella surface 9, that is, reduces the load on the rib 10 and the column 5, and ensures the service life of the garden umbrella. At the same time, the force on the top of the column 5 is always toward the axis of the base 1, which prevents the garden umbrella from tipping over.

[0020] like Figure 1 , Figure 2As shown, a windbreaker 13 is fixedly connected to the side of the connecting rod 6 close to the umbrella surface 9. Along the direction from the column 5 toward the supporting rod 7, the projected area of ​​the windbreaker 13 is at least one-third of the projected area of ​​the umbrella surface 9. The side of the windbreaker 13 away from the umbrella surface 9 forms a convex arc surface. A guide plate 28 is fixedly connected to the edge of the umbrella surface 9 close to the column 5. An acute angle is formed between the guide plate 28 and the umbrella surface 9, with the opening facing the supporting column. A control console 19 is fixedly connected to the top surface of the turntable 25. The control console 19 is electrically connected to the rotating motor 2, and a reinforcing rib 20 is provided between the control console 19 and the column 5.

[0021] Specifically, the outer wall of the windbreaker 13 fits the outer wall of the connecting rod 6, the windbreaker 13 and the connecting rod 6 are integrally formed, the width of the bottom end of the windbreaker 13 is greater than the width of the top end of the windbreaker 13, one end of the control console 19 is located above the rotating motor 2, and the other end of the control console 19 is in conflict with the column 5. The cross-section of the reinforcing rib 20 is triangular, and the control console 19 provides manual operation for the operation of the rotating motor 2, allowing the user to adjust the patio umbrella according to needs, while lowering the center of gravity of the patio umbrella, further preventing the patio umbrella from tipping over, and the control console 19 supports the column 5 through the triangular plate-shaped reinforcing rib 20, thereby improving the load-bearing capacity of the column 5, and at the same time Compared with the diameter of the ribs 10, the diameter of the column 5 is larger and can withstand a larger load. Therefore, by providing the windbreak plate 13, more load is shared on the connecting rod 6 and the column 5. There is only a small gap between the windbreak plate 13 and the umbrella surface 9. The windbreak plate 13 guides the airflow to flow through both sides of the windbreak plate 13, and a weak resistance area is formed on the leeward side of the windbreak plate 13, further reducing the load on the umbrella surface 9 and the ribs 10. The guide plate 28 is made of flexible ABS plastic and is bonded to the edge of the umbrella surface 9. The two guide plates 28 are located between the three ribs 10 closest to the column 5. The guide plates 28 make the opened umbrella surface 9 closer to a streamlined structure.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, a storage box 14 is fixedly connected to the top of the column 5, and storage grooves 15 are opened on both sides of the storage box 14. The bottom end of the side wall of the storage groove 15 is rotatably connected to a rotating shaft 16, and a number of fan ribs 17 are rotatably connected to the rotating shaft 16. A number of fan ribs 17 are glued with fan surfaces 18, and the fan surfaces 18 are connected to a number of fan ribs 17. The fan rib 17 farthest from the support rod 7 is fixedly connected to the side wall of the storage groove 15, and the fan rib 17 closest to the support rod 7 is detachably connected to the side wall of the storage groove 15.

[0023] Specifically, the storage box 14 is detachably connected to the column 5 by a hoop and bolts, and the storage box 14 is located between the column 5 and the support column, and the two ends of the rotating shaft 16 are respectively inserted into the two side walls of the storage groove 15, and the fan rib 17 farthest from the support rod 7 is fixedly connected to the side wall of the storage groove 15 by bolts, and the top of the fan rib 17 closest to the support rod 7 is embedded with a magnetic block, and the side wall of the storage groove 15 is also embedded with a corresponding magnetic block. The fan rib 17 closest to the support rod 7 is detachably connected to the side wall of the storage groove 15 through the suction force between the magnetic blocks. Because with the cooperation of the wind direction sensor 11 and the rotating motor 2, the storage box 14 is always located on the windward side of the user. When a user takes shelter from the rain under the garden umbrella, the unfolded fan surface 18 can reduce the rainwater that is carried by the airflow and reaches under the umbrella surface 9, thereby improving the rain shelter effect of the garden umbrella.

[0024] Embodiment 2: A control process of a wind-resistant garden umbrella, including an automatic control process and a manual control process; The automatic control process includes: S11, when the wind speed sensor 12 detects that the wind speed exceeds the preset maximum wind speed, the wind speed sensor 12 transmits a start signal to the rotating motor 2; S12, the wind direction sensor 11 detects the wind direction, and the rotating motor 2 rotates the turntable 25 according to the wind direction signal, so that the column 5 is located on the windward side of the axis of the turntable 25; S13, when the wind speed sensor 12 detects that the wind speed is lower than the preset minimum wind speed, the wind speed sensor 12 transmits a shutdown signal to the rotating motor 2; The console 19 is provided with a clockwise button 21, a counterclockwise button 22, a stop button 23, and an automatic button 24. The manual control process includes: S21, pressing the stop button 23 to stop the rotation of the rotating motor 2; S22, pressing the clockwise button 21 or the counterclockwise button 22 to make the rotating motor 2 rotate clockwise or counterclockwise; S23, pressing the stop button 23 to stop the rotation of the rotating motor 2; S24, press the automatic button 24 to enter the automatic control process.

[0025] Specifically, when the wind speed exceeds the preset maximum wind speed, the wind may affect the normal use of the garden umbrella. The rotating motor 2 is started to rotate the column 5 to the windward side of the support rod 7 to reduce the impact of the wind on the garden umbrella. When the wind speed drops below the preset minimum wind speed, the impact of the wind on the garden umbrella is small. The rotating motor 2 and the wind direction sensor 11 are turned off, and only the wind speed sensor 12 is powered to save electricity. The preset maximum wind speed is greater than the preset minimum wind speed to ensure that the external airflow has stabilized within a lower range when the wind speed drops below the preset minimum wind speed. The manual control process has a higher priority than the automatic control process. Pressing any one of the clockwise button 21, the counterclockwise button 22, and the stop button 23 will terminate the automatic control process until the user presses the automatic button 24.

[0026] A bearing plate 26 is provided on the top surface of the turntable 25, and a pressure sensor 27 is provided between the bearing plate 26 and the turntable 25. The pressure sensor 27 is electrically connected to the rotating motor 2. Specifically, the rotating motor 2 has a low speed gear and a high speed gear. When the bearing plate 26 is unloaded, the value detected by the pressure sensor 27 is small, and the rotating motor 2 is in the high speed gear when it is started. When there is a person or object on the bearing plate 26, the value detected by the pressure sensor 27 is large, and the rotating motor 2 is in the low speed gear when it is started, which ensures the adjustment speed of the garden umbrella when the bearing plate 26 is unloaded, and ensures the stability of the rotation of the turntable 25 when there is a person or object on the bearing plate 26.

[0027] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
