Problems solved by technology

[0002]Existing telescopic rods are generally composed of a group of sleeves with different diameters that are sheathed together, and their length can be manually extended or shortened, but not automatically Elongated or shortened, causing inconvenience to use
Some telescopic rods can be automatically extended and retracted. Generally, a built-in motor drives a multi-section threaded sleeve to realize the longitudinal telescopic movement of the telescopic rod. their application scenarios
[0003] The holographic fan in the prior art usually uses a light bar welded with lamp beads on a long rigid PCB substrate as a display component. Many LED lamp beads are distributed on the long light bar. The bar-shaped light bar is installed on the motor shaft in the shape of fan blades. According to the number of groups of light bars, there are various structural forms such as "one" shape and "ten" shape, such as figure 1 and figure 2 As shown, when the motor drives the light bar to rotate, 3D graphics are generated, but the length of the elongated light bar is generally fixed, and it will be inconvenient to store and transport when carrying it. The length of the light bar can be used to change the size of the display graphics, even if the adaptability to the scene requirements is relatively poor. In order to change the maximum display graphics by changing the length of the light bar, it is necessary to produce various holographic fans with different light bar lengths.
[0004] Due to the above-mentioned problems, the holographic fan carried by the UAV in the prior art also has the problem of inconvenient carrying and storage and transportation, and the size of the displayed graphics cannot be changed by changing the length of the light bar during use. Poor adaptability to scene requirements

Embodiment 1

[0073] like Figure 3 to Figure 8 As shown, it includes a holographic fan body 1 , a display device 2 and a rotary drive device 3 for driving the display device 2 .

[0074] As a further description of this embodiment, the display device 2 is radially installed along the rotation axis 31 of the rotary drive device 3 , the display device 2 is provided with at least two groups, and each group of the display devices 2 surrounds the The outer ends of the rotary drive devices 3 are uniformly arranged in a circular matrix in the radial direction. Generally, the number of the display devices 2 is set in two groups, four groups, six groups, eight groups, etc., and each group of the display devices 2 is arranged in a circular matrix on the outer end surface of the rotary driving device 3 . in this example Figure 3 to Figure 8 Among them, the display device 2 is provided with two groups.

[0075] As a further description of the present embodiment, a group of the display devices 2 in...

Embodiment 2

[0088] see Figure 9, the difference from Embodiment 1 is: the flexible display device 21 includes a reel 211 and a flexible display assembly 212, the reel 211 is arranged in the fixed arm section 221, and one end of the flexible display assembly 212 is rolled Winding on the reel 211, the upper part of the last stage boom section 222 is provided with the last stage boom section opening 2222, and the other end of the flexible display assembly 212 is fixed on the outer end top surface 2211 of the fixed boom section, so The other end of the flexible display assembly 212 passes through the telescopic rod 22 and reaches the final boom section 222, then passes upward through the final boom section opening 2222, and lays flat on the outer top surface 224 of the telescopic rod.

[0089] As a further description of this embodiment, guide wheels 214 are provided at the turning corners of the flexible display assembly 212 . In this embodiment, see Figure 9 , the guide wheel 214 is arr...

Embodiment 3

[0091] The difference from Embodiment 1 is that the flexible display device 21 includes a reel 211 and a flexible display assembly 212, the reel 211 is arranged in the final arm section 222, and one end of the flexible display assembly 212 is rolled up. Winding on the reel 211; the other end of the flexible display component 212 is disposed on the outer top surface 2211 of the fixed arm section through the outlet 2111 provided at the reel 211 for the flexible display component 212 to pass through.

[0092] Specifically, see Figure 10 , the reel 211 is arranged on the last stage arm section 222, and the outlet 2111 provided at the storage bin 213 corresponding to the reel 211 for the flexible display assembly 212 to pass through, and the flexible display assembly 212 is laid flat on the telescopic rod. on the top surface 224 of the outer end. Therefore, one end of the flexible display assembly 212 is wound on the reel 211, and the other end of the flexible display assembly 21...

Abstract

The invention relates to the field of holographic fans, and particularly discloses a holographic fan and an unmanned aerial vehicle carrying the same, the holographic fan comprises a holographic fan body, at least two sets of display devices, a rotation driving device for driving the display devices and a power supply display control device, and the display devices are installed in the radial direction of a rotating shaft of the rotation driving device; each group of display devices are uniformly arranged in a circumferential matrix in the radial direction around the outer side end of the rotary driving device, one group of display devices comprises a flexible display device and a telescopic rod for supporting the flexible display device, the flexible display device comprises a winding drum and a flexible display assembly, and the winding drum is arranged in the fixed arm section or the last-stage arm section. Due to the fact that the flexible display assembly with the variable length is adopted in the holographic fan, the holographic fan can be contracted and stored when carried, transportation is convenient, the size of a displayed graph can be changed by changing the length of the light bar when the holographic fan is used, and adaptability to scene requirements is high.
