[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1 , Figure 2 and Figure 3 As shown, a UAV flying canopy capable of reducing wind resistance comprises a suspension 1, a UAV body 2 is mounted on the suspension 1, four rotors 3 are mounted on the UAV body 2, a plurality of light bars 4 are mounted on the suspension 1, a driving structure 5 is provided on the suspension 1, a supporting structure 6 is provided on the suspension 1, the plurality of light bars 4 are distributed in an arc shape, and the distance between two adjacent light bars 4 is equal.
[0021] As a technical optimization solution of the utility model, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the support structure 6 includes a connecting shaft 601 and a support rod 602, the suspension 1 is rotatably connected to two connecting shafts 601, two support rods 602 are fixedly connected at both ends of the connecting shaft 601, the ends of the support rods 602 are slidably connected with a sliding column 603, one end of the sliding column 603 is fixedly connected with a support block 604, a buffer spring 605 is sleeved on the outside of the sliding column 603, one end of the buffer spring 605 is fixedly connected to the support block 604, and the other end of the buffer spring 605 is fixedly connected to the support rod 602, the two connecting shafts 601 are symmetrically distributed about the middle part of the suspension 1, the two support rods 602 are symmetrically distributed about the middle part of the connecting shaft 601, the cross-section of one end of the support rod 602 is an L-shaped structure, and the sliding column 603 and the support block 604 are in a T-shaped structure, so it can play a buffering role when the flying canopy lands, and at the same time can improve the stability of the flying canopy when it is placed after landing.
[0022] As a technical optimization solution of the utility model, Figure 1 and Figure 2As shown, the driving structure 5 includes an electric push rod 501 and a connecting block 502. The electric push rod 501 is installed on the suspension 1. One end of the electric push rod 501 is fixedly connected to the connecting block 502. The connecting block 502 is rotatably connected to a connecting rod 503. The connecting rod 503 is rotatably connected to a rocker arm 504. The rocker arm 504 is fixedly connected to a connecting shaft 601. The rocker arm 504 is perpendicular to the connecting shaft 601. The rocker arm 504 is arranged in the middle of the connecting shaft 601. Therefore, when the flying canopy lands, the four support rods 602 can be unfolded at the same time.
[0023] When the utility model is in use, the suspension 1 can be moved to a high altitude by rotating the multiple rotors 3 on the drone body 2, and the multiple light bars 4 will be moved to a high altitude together with the suspension 1, so as to facilitate the display of content at a high altitude through the multiple light bars 4, and because the multiple light bars 4 are evenly distributed in an arc shape, the light bars 4 are not only spaced apart in the horizontal direction, but also in the vertical direction, so as to better reduce wind resistance, and when the flying canopy needs to land, the two electric push rods 501 can be started at the same time, and the contraction of the electric push rods 501 will drive the connecting block 502 to move, and the movement of the connecting block 502 will drive the swing rod 504 to rotate through the connecting rod 503, and the swing rod 504 will drive the connecting shaft 601 to rotate, and the rotation of the connecting shaft 601 will drive the two support rods 602 to rotate, so that the four support rods 602 can be rotated. The support rods 602 are unfolded at the same time. When the support rods 602 rotate ninety degrees, the electric push rod 501 stops shrinking. At this time, the position of the bottom end of the support block 604 is lower than the position of one of the lowest light strips 4. Therefore, during the landing of the flying canopy, the four support blocks 604 will contact the ground. At the moment when the support blocks 604 contact the ground, the buffer springs 605 will shrink under the action of the impact force, and the slide column 603 will slide on the support rods 602, so that the flying canopy can be buffered by multiple buffer springs 605, avoiding the flying canopy from being damaged by a large impact force, thereby effectively improving the safety of use. Since the multiple light strips 4 are distributed in an arc shape, when the flying canopy lands, the contact between the four support blocks 604 and the ground can also improve its stability when placed, making it more convenient to use.
