[0026] As Figures 1 to 2As shown, a 3D holographic display unmanned aerial vehicle includes an unmanned aerial vehicle body 1, which can present a plurality of angle stereoscopic holographic images in the air, has good advertising effect, and the overall structure is light, which can reduce the bearing pressure of the unmanned aerial vehicle, thereby reducing the overall advertising cost. The two sides of the unmanned aerial vehicle body 1 of the embodiment are symmetrically provided with a plurality of connecting arms 2, including but not limited to 4, 6, 8, etc. The end of each connecting arm 2 away from the unmanned aerial vehicle body 1 is provided with a mounting seat 3, and the mounting seat 3 is provided with a driving mechanism 4. The top output end of the driving mechanism 4 of the embodiment is provided with a paddle assembly 5, so that when the driving mechanism 4 is started, the paddle assembly 5 can be driven to rotate, so that the unmanned aerial vehicle is driven to fly by the paddle assembly 5.

[0027] In order to realize picture display, the bottom output end of the driving mechanism 4 of the embodiment is also connected with a holographic fan screen assembly 6, so that when the driving mechanism 4 drives the paddle assembly 5 to rotate to make the unmanned aerial vehicle fly, the holographic fan screen assembly 6 can also be driven to rotate. When the holographic fan screen assembly 6 reaches a certain rotating speed, 3D holographic pictures can be displayed under the action of rotating scanning display technology (pov) and human eye persistence principle, so that the stereoscopic holographic image display at multiple angles in the air is realized, the audience can watch from various angles, and good visual picture display and advertising effect are achieved.

[0028] In addition, the bottom of each mounting seat 3 of the embodiment is provided with a group of holographic fan screen assemblies 6 connected with the bottom output end of the driving mechanism 4, so that the weight of each position of the unmanned aerial vehicle body can be balanced, thereby facilitating the stable flight of the unmanned aerial vehicle and realizing good display effect. In addition, the pictures of each holographic fan screen assembly 6 can be spliced with each other, which can improve the display and propaganda quality of the embodiment.

[0029] As shown in the figure, Figure 2 In one embodiment, the driving mechanism 4 is a double-shaft driving motor, and the top and bottom thereof are respectively provided with an upper end shaft and a lower end shaft. The paddle assembly 5 is in transmission connection with the upper end shaft, and the holographic fan screen assembly 6 is in transmission connection with the lower end shaft, so that when the driving motor is started, the paddle assembly 5 and the holographic fan screen assembly 6 can be driven to rotate at the same time, thereby realizing the flight of the unmanned aerial vehicle body and the display of the holographic picture at the same time, realizing the high-altitude holographic display and propaganda effect of the embodiment, and reducing the overall cost of the advertising unmanned aerial vehicle.

[0030] In another embodiment, the drive mechanism 4 may also include two propeller motors and a display motor, which are vertically connected to the top and bottom of the mounting base 3, respectively. The propeller assembly 5 is driven by the output end of the propeller motor, and the holographic fan screen assembly 6 is driven by the output end of the display motor. This allows the propeller assembly 5 and the holographic fan screen assembly 6 to rotate under the drive of the propeller motor and the display motor, respectively, thereby realizing the flight of the drone body and the display of the holographic image. This allows the staff to adjust the flight speed of the drone and the display effect of the image individually according to the actual situation, which can further improve the advertising and display effect of the advertising drone.

[0031] After the propeller assembly 5 and the holographic fan screen assembly 6 in this embodiment are installed, they can be located at the upper and lower ends of the mounting base 3, respectively. This avoids the holographic fan screen assembly 6 from affecting the rotation and flight of the propeller assembly 5, and at the same time, it makes it convenient for users to look up from the ground and view the holographic image displayed by the holographic fan screen assembly 6.

[0034] Specifically, as shown in the drawings, Figure 4 In the embodiment, a plurality of connecting brackets 611 are arranged at equal angles at the edge of the rotating disc 61, and the connecting bracket 611 is provided with a mounting groove 612, so that each fan blade 62 can be connected in the mounting groove 612 to realize the connection with the connecting bracket 611, thereby realizing the display of the holographic picture.

[0035] In order to obtain good display effect when the holographic fan screen assembly 6 rotates, the number of fan blades 62 is at least two, so that the picture viewed according to the human eye persistence principle after the rotation of the fan blade 62 can be clearer and more uniform; in other embodiments, the number of fan blades 62 can be, but is not limited to, 3, 4, 5, 6, etc., and as the number of fan blades 62 increases, the required rotating speed is lower and the displayed picture is clearer. In the embodiment, the number of fan blades 62 is four, which can effectively reduce the overall cost of the advertising unmanned aerial vehicle while ensuring the display effect of the picture.

[0036] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, the holographic fan screen assembly 6 of the embodiment is arranged at the bottom of the mounting seat 3, so that it can be located at the bottom of the propeller assembly 5 for picture display, which can reduce the space occupation of the unmanned aerial vehicle body 1 and facilitate the miniaturization design of the advertising unmanned aerial vehicle; and the bottom space of the unmanned aerial vehicle body 1 is also left, and the embodiment installs a foot stand 8 at the bottom of the unmanned aerial vehicle body 1, so that when the unmanned aerial vehicle lands, it can be supported by the foot stand 8, and damage to the unmanned aerial vehicle body 1 can be avoided.

[0037] To sum up, the embodiment sets the mounting seat 3 at the end of the connecting arm 2 of the UAV main body 1, and sets the propeller assembly 5 and the holographic fan screen assembly 6 coaxially at the top and bottom of the mounting seat 3, so that when the UAV main body 1 flies through the propeller assembly 5, the holographic fan screen assembly 6 can display three-dimensional holographic images at multiple angles at the bottom of the propeller assembly 5, which is convenient for the audience to watch from various angles, has good visual image display and advertising effect, and through the installation of the holographic fan display screen at the bottom of the propeller assembly 5, the space occupation of the UAV main body 1 can be reduced, the miniaturization design of the advertising UAV is facilitated, the structure is simple, the bearing pressure of the UAV can be reduced, and the cost of the UAV is reduced.
