Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] The drone with an aerial display screen disclosed by the present invention is mainly used in scenarios where drones with screens have poor stability, short service life, and difficulty in transportation.

[0028] In this embodiment, Figure 1 It can be seen that the drone is composed of components such as a main rod 1, a fixed rod 2, a first support rod 3, a lifting rod 8 and a connecting rod 15. As shown in the figure, the drone is in an unfolded state. At this time, multiple drones can be controlled by a remote control. The four motors 18 rotate, driving the multiple blades 17 to rotate, blowing air downward to make the drone take off. Each drone has four display screens, namely a first display screen 10, a second display screen 11, a third display screen 12 and a fourth display screen 13. Multiple drones can form a huge display screen in the air, which can be used for video playback of various activities or light shows held at festivals, etc., and the drone screen and battery of the present application are respectively arranged at the head and tail of the drone, which make the drone more stable during flight, and the airflow generated by the blades between the two during rotation will not affect the stability of the screen.

[0029] Among them, the display screen of the present application can adopt an LED grid screen, so that the entire display screen appears hollow, ensuring that airflow can pass through smoothly, reducing wind resistance, and improving the stability of drone flight.

[0030] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 In a preferred embodiment, the sliding folding mechanism includes a baffle 36 fixedly connected to one end of the main rod 1, a base 37 is fixedly connected to one side of the baffle 36, a rotating block 38 is rotatably connected to the top of the base 37, a fixed rail 39 is fixedly connected to one side of the rotating block 38, and a sliding plate 35 is slidably connected to one side of the fixed rail 39; An upper display screen mechanism is installed on one side of the sliding plate 35, and the upper display screen mechanism is used to assemble the upper display screen.

[0031] The upper display screen mechanism includes a first bolt 40 rotatably connected to the bottom of one side of the sliding plate 35, a second bolt is rotatably connected to one side of the sliding plate 35, one end of the first bolt 40 is rotatably connected to the first display screen 10, one end of the first bolt 40 is threadedly connected to a first nut 41 near one side of the first display screen 10, one end of the second bolt is rotatably connected to the second display screen 11, and one end of the second bolt is threadedly connected to a second fixing nut near one side of the second display screen 11.

[0032] In this embodiment, the first nut 41 and the second fixing nut are fixed, and the first bolt 40 and the second bolt are rotated respectively, so that the first nut 41 and the second fixing nut are separated from the first display screen 10 and the second display screen 11 respectively, so that the first display screen 10 and the second display screen 11 can slide or rotate on the first bolt 40 and the second bolt, and the sliding plate 35 is driven to slide upward by sliding the first display screen 10 and the second display screen 11 upward, and then the sliding plate 35, the rotating block 38 and the fixing rail 39 are rotated to make the first display screen 10 and the second display screen 11 flip over to the top of the main rod 1 and be placed horizontally. Since the first display screen 10 and the second display screen 11 are on the same plane and have the same height, the first display screen 10 or the second display screen 11 can be slid on the first bolt 40 and the second bolt, so that the heights of the first display screen 10 and the second display screen 11 are staggered. At this time, the first display screen 10 and the second display screen 11 can be rotated so that the first display screen 10 and the second display screen 11 are relatively rotated and stacked together. Folding can reduce the space occupied by the first display screen 10 and the second display screen 11, so as to achieve the effect of folding the first display screen 10 and the second display screen 11.

[0033] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 In a preferred embodiment, the flipping and folding mechanism includes two mounting frames 34 fixedly connected to one end of the main rod 1, the bottom of the mounting frame 34 is rotatably connected to a folding arm 33, one end of the folding arm 33 is rotatably connected to a vertical shaft 32, and one side of the vertical shaft 32 is rotatably connected to a horizontal shaft 31; A lower display screen mechanism is installed at one end of the horizontal axis 31, and the lower display screen mechanism is used to assemble the lower display screen.

[0034] The lower display screen mechanism includes a third display screen 12 and a fourth display screen 13 respectively fixedly connected to one end of the horizontal axis 31. The mounting frame 34 is symmetrically installed, so there are also two horizontal axes 31. The outer surfaces of the first display screen 10, the second display screen 11, the third display screen 12 and the fourth display screen 13 are respectively provided with a plurality of resistance openings 30, and the gaps where the first display screen 10 and the second display screen 11 and the third display screen 12 and the fourth display screen 13 contact are respectively provided with a plurality of card plates 42.

[0035] In this embodiment, by rotating the third display screen 12 and the fourth display screen 13 outward respectively, since there are multiple degrees of freedom between the horizontal axis 31 and the mounting frame 34, the third display screen 12 and the fourth display screen 13 can be rotated at any angle, and the third display screen 12 and the fourth display screen 13 are rotated to the bottom of the main pole 1. Since the third display screen 12 and the fourth display screen 13 are thin and the material has a certain toughness, the third display screen 12 and the fourth display screen 13 can be staggered with each other so that the third display screen 12 and the fourth display screen 13 are stacked together. By folding the first display screen 10, the second display screen 11, the third display screen 12 and the fourth display screen 13 respectively, the space occupied by the drone and the display screen is reduced, and the impact resistance of the equipment is increased, so that the drone and the display screen are not easily damaged, which facilitates the transportation and storage of the display screen and the drone. During the take-off and landing of the drone, the fixing rod 2, the first support rod 3 and the second support rod 19 support the drone.

[0036] What needs to be explained more is that after use, the drone lands, and the first display screen 10, the second display screen 11, the third display screen 12 and the fourth display screen 13 are loosened respectively by removing the plurality of card plates 42.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the first display screen 10, the second display screen 11, the third display screen 12 and the fourth display screen 13 are combined into a complete screen, and a large number of drones are hovering in the air. Each drone is controlled by a precise automated algorithm, and a large number of drones are combined into a larger screen in the air (this is a prior art and will not be repeated here), displaying a larger video or pattern. The drone automated algorithm control can also coordinate the speed of multiple motors 18 according to the wind in the air, adjust the lift, and thus control the hovering of the drone to achieve smooth playback of the video or pattern. One end of the main rod 1 is fixedly connected to a support plate 6 near the mounting plate 4, and one end of the main rod 1 is located between the battery 5 and the fixed plate 7 and is fixedly connected to an auxiliary plate 14.

[0038] In this embodiment, the first display screen 10 and the second display screen 11 are rotated relative to each other and stacked together, and placed on the upper surface of the support plate 6. The support plate 6 can support the first display screen 10 and the second display screen 11. The third display screen 12 and the fourth display screen 13 are stacked together and placed on the upper surface of the auxiliary plate 14. The auxiliary plate 14 supports the third display screen 12 and the fourth display screen 13.

[0039] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In a preferred embodiment, the bracket folding mechanism includes a sliding rod 16 fixedly connected to one side of the connecting rod 15, and the two ends of the sliding rod 16 are respectively fixedly connected to the fixing rings 29, and the two ends of the sliding rod 16 are respectively slidably connected to the connecting blocks 25 on one side close to the fixing ring 29, and one side of the connecting block 25 is fixedly connected to the spring 28, and one end of the spring 28 is fixedly connected to the sliding ring 26, and one side of the sliding ring 26 is threadedly connected to the screw 27; A supporting mechanism is installed at the bottom of the connecting block 25, and the supporting mechanism is used to support the drone.

[0040] The supporting mechanism includes a first supporting rod 3 which is rotatably connected to both ends of the connecting rod 15, one end of the first supporting rod 3 is fixedly connected to the fixing rod 2, the middle position of the fixing rod 2 is rotatably connected to the rotating rod 24, one end of the first supporting rod 3 is rotatably connected to the second supporting rod 19 near the fixing rod 2, one end of the first supporting rod 3 is fixedly connected to the upper fixing block 23 near the fixing rod 2, the bottom of the upper fixing block 23 is fixedly connected to the upper magnet 22, the top of the second supporting rod 19 is fixedly connected to the lower fixing block 20, and the top of the lower fixing block 20 is fixedly connected to the lower magnet 21.

[0041] The battery 5 and the controller 9 are electrically connected, the controller 9 and the multiple motors 18 are electrically connected, and the controller 9 and the first display screen 10, the second display screen 11, the third display screen 12 and the fourth display screen 13 are also electrically connected. The first display screen 10 and the second display screen 11 can slide and rotate on the first bolt 40 and the second bolt respectively.

[0042] The mass of the battery 5 is similar to that of the first display screen 10 , the second display screen 11 , the third display screen 12 and the fourth display screen 13 , which can maintain the balance of both ends of the main rod 1 . The top end of the rotating rod 24 is rotatably connected to the connecting block 25 .

[0043] In this embodiment, during the impact with the ground, the second support rod 19 and the fourth display screen 13 push the rotating rod 24, and the rotating rod 24 drives the connecting block 25 to compress the spring 28, thereby eliminating the vibration and protecting the drone.

[0044] What needs to be explained more is that by rotating the screw 27, the sliding ring 26 slides on the sliding rod 16, the connecting block 25 and the spring 28 can slide toward the center on the sliding rod 16, the fixed rod 2 and the rotating rod 24 rotate relative to each other, and the first support rod 3 and the connecting rod 15 rotate relative to each other, so that the first support rod 3 and the sliding rod 16 are rotated from vertical to horizontal, which has the effect of folding the first support rod 3, greatly reducing the height of the UAV, so that multiple UAVs can be placed in a limited height, and the probability of damage to the first support rod 3 of the UAV is also reduced.

[0045] Furthermore, by separating the lower magnet 21 and the upper magnet 22, the first support rod 3 and the second support rod 19 are rotated relative to each other, and the second support rod 19 is rotated to contact the fixed rod 2, so that the bottom of the drone is more concise and the effect of multiple second support rods 19 at the bottom of the drone is protected.

[0046] Working principle: When in use, it can be seen from the figure that the drone is composed of components such as a main rod 1, a fixing rod 2, a first support rod 3, a lifting rod 8 and a connecting rod 15. As shown in the figure, the drone is in an unfolded state. At this time, multiple drones can be controlled by a remote controller. The four motors 18 rotate, driving multiple blades 17 to rotate, blowing air downward to make the drone take off. Each drone has four display screens, namely a first display screen 10, a second display screen 11, a third display screen 12 and a fourth display screen 13. Multiple drones can form a huge display screen in the air, which can be used for video playback of various activities or light shows held at festivals. After use, the drone lands, and the first display screen 10, the second display screen 11, The third display screen 12 and the fourth display screen 13 are loosened respectively, the first nut 41 and the second fixing nut are fixed, and the first bolt 40 and the second bolt are rotated respectively to separate the first nut 41 and the second fixing nut from the first display screen 10 and the second display screen 11 respectively, so that the first display screen 10 and the second display screen 11 can slide or rotate on the first bolt 40 and the second bolt, and the sliding plate 35 is driven to slide upward by sliding the first display screen 10 and the second display screen 11 upward, and then the sliding plate 35, the rotating block 38 and the fixing rail 39 are rotated to turn the first display screen 10 and the second display screen 11 over to the top of the main rod 1 and place them horizontally. Since the first display screen 10 and the second display screen 11 are on the same plane and have the same height, the first display screen 10 and the second display screen 11 can be turned upward. The first display screen 10 or the second display screen 11 slides on the first bolt 40 and the second bolt, so that the heights of the first display screen 10 and the second display screen 11 are staggered. At this time, the first display screen 10 and the second display screen 11 can be rotated so that the first display screen 10 and the second display screen 11 are relatively rotated and stacked together and placed on the upper surface of the support plate 6. The support plate 6 can support the first display screen 10 and the second display screen 11. Folding can reduce the space occupied by the first display screen 10 and the second display screen 11, so as to achieve the effect of folding the first display screen 10 and the second display screen 11. By rotating the third display screen 12 and the fourth display screen 13 outwards respectively, since there are multiple degrees of freedom between the horizontal axis 31 and the mounting frame 34, the third display screen 12 and the fourth display screen 13 can be folded. The third display screen 12 and the fourth display screen 13 can be rotated at any angle, and the third display screen 12 and the fourth display screen 13 are rotated to the bottom of the main pole 1. Since the third display screen 12 and the fourth display screen 13 are relatively thin and the material has a certain toughness, the third display screen 12 and the fourth display screen 13 can be staggered with each other, so that the third display screen 12 and the fourth display screen 13 are stacked together and placed on the upper surface of the auxiliary plate 14. The auxiliary plate 14 plays the role of supporting the third display screen 12 and the fourth display screen 13. By folding the first display screen 10, the second display screen 11, the third display screen 12 and the fourth display screen 13 respectively, the space occupied by the drone and the display screen is reduced, and the impact resistance of the equipment is increased, so that the drone and the display screen are not easily damaged.It facilitates the transportation and storage of the display screen and the UAV. During the take-off and landing of the UAV, the fixed rod 2, the first support rod 3 and the second support rod 19 support the UAV. During the impact of the ground, the second support rod 19 and the fourth display screen 13 push the rotating rod 24, and the rotating rod 24 drives the connecting block 25 to compress the spring 28, thereby eliminating vibration and protecting the UAV. By rotating the screw 27, the sliding ring 26 slides on the sliding rod 16, so that the connecting block 25 and the spring 28 can slide toward the center on the sliding rod 16, and the fixed rod 2 and the rotating rod 24 can be rotated. Relative rotation, the first support rod 3 and the connecting rod 15 rotate relative to each other, so that the first support rod 3 and the sliding rod 16 rotate from vertical to horizontal, which has the effect of folding the first support rod 3, greatly reducing the height of the drone, so that multiple drones can be placed in a limited height, and also reducing the probability of damage to the first support rod 3 of the drone. By separating the lower magnet 21 and the upper magnet 22, the first support rod 3 and the second support rod 19 rotate relative to each other, and the second support rod 19 is rotated to contact with the fixed rod 2, making the bottom of the drone more concise, and also protecting the effect of multiple second support rods 19 at the bottom of the drone.
