[0022] The airbag body is arranged in a "cathode ray tube shape", the top of the airbag body is a transparent flat plane, the top area is smaller than the bottom area, the projection module 20 is arranged outside the transparent flat plane on the top of the airbag body 10, and the projection film 30 is arranged at the bottom of the airbag body 10; the projection module 20 converts the digital signal into a light signal and amplifies and projects it onto the projection film 30.

[0023] The control module 40 and the multi-rotor flight control system 50 are arranged outside the airbag body 10; the multi-rotor flight control system 50 is used for the aerial maneuvering and positioning hovering of the aerostat.

[0024] The projection film 30 is a rear projection film.

[0025] like Figure 1 As shown, the airbag body is arranged in a "cathode ray tube shape", presenting a structure that is small at the top and large at the bottom. The projection module 20 is arranged on the top plane of the airbag body facing the outside of the airbag, and the projection film 30 is arranged at the bottom of the airbag body. The lens of the projection module 20 is facing the projection film 30. By adjusting the screen size and focal length, the image in the lens of the projection module 20 can be projected onto the projection film 20 by rear projection. The "cathode ray tube shape" is designed with reference to the appearance of an old-style TV. The projection module 20 is installed on a flat plane at the top of the airbag and projects to the bottom of the airbag. Compared with the solution of installing the projection module 20 on the side of the airbag, the installation is less difficult, the coverage angle is large, and a more stable and realistic image can be presented.

[0026] In the embodiment of the utility model, the aerostat needs to maintain a lifted state, and the weight of the equipment carried must be strictly controlled. It is necessary to select a miniaturized and lightweight projection module 20 and a power supply to reduce the overall weight.

[0027] In the embodiment of the utility model, the projection module 20 adopts an LED light source or a laser light source. The projection module 20 of the LED light source and the laser light source has a high brightness output, and can overcome the interference of natural light in daytime and high brightness environments, while maintaining high energy efficiency and long life.

[0028] In the embodiment of the utility model, the projection module 20 integrates an automatic focus and image correction module to adapt to the image deviation caused by the slight shaking of the aerostat in the air.

[0029] The aerial environment is complex and changeable, including wind, temperature, humidity, etc. The projection module needs to have characteristics such as waterproof, dustproof, high temperature or low temperature resistance, etc. to ensure stable operation under various climatic conditions. In the embodiment of the utility model, the projection module 20 is provided with a dustproof and waterproof device. If used in a high temperature or low temperature environment, the projection module 20 needs to have a temperature control function.

[0030] In some embodiments of the present invention, considering the particularity of the operation of the aerostat, the projection module 20 supports remote wireless control, including functions such as switching, content switching, and brightness adjustment.

[0031] In some embodiments of the present invention, the projection film 30 is a thin film formed by projection paint sprayed uniformly on the outside of the transparent flat surface at the bottom of the airbag body 10. The projection paint is sprayed on the side of the bottom plane of the airbag body facing the outside of the airbag.

[0032] In other embodiments of the utility model, the projection film 30 is attached to the outside of the transparent flat surface at the bottom of the airbag body 10 or is bonded and fixed to the airbag body 10 as the bottom of the airbag body 10, and the projection film 30 uses a high-imaging composite material to support the rear projection function. Cloth screens and lightweight plastic screens can only form clear and bright images by reflecting the light of the projector on the front of the screen, while high-imaging composite materials can form images by rear projection. When the projection film 30 is directly used as the bottom of the airbag body 10, the projection film 30 is cut into a shape and size that matches the bottom of the airbag body 10 and bonded and fixed to the airbag body 10.

[0033] In actual applications, it is necessary to design the structure of the airbag body 10 and the projection film 30 according to the size and projection ratio of the projection module 20. The area of ​​the flat plane at the top of the airbag is larger than the bottom size of the projection module. The vertical distance between the flat plane at the top of the airbag and the flat plane at the bottom of the airbag is adjusted according to the size and projection ratio of the projection film, or the size of the projection film is adjusted according to the vertical distance and projection ratio between the flat plane at the top of the airbag and the flat plane at the bottom of the airbag.

[0034] The material of the airbag body 10 is one of aluminum oxide-plated composite material, silicon oxide-plated composite material, modified PE, TPU, and PVC, and the gas inside the airbag body 10 is one of helium and hydrogen. The material of the airbag body is not limited to the above materials, and any other suitable materials are included in the protection scope of the present utility model.

[0035] The size and inflation volume of the airbag body 10 also need to be adjusted according to the weight of the equipment carried by the airbag.

[0036] In the embodiment of the utility model, the control module 40 is internally provided with a sensor, a remote control receiving device, and a positioning system. The control module can obtain the balance state of the entire system through the sensor; the remote control receiving device is used to receive ground remote control commands; and the positioning system is used to locate the position of the aerostat.

[0037] In an embodiment of the utility model, the aerostat further comprises a power supply, which is electrically connected to the projection module and the control module. The power supply is a battery or a combination of a battery and a solar panel.

[0038] In the embodiment of the utility model, the aerostat further includes a multi-rotor flight control system 50, which provides the aerostat with autonomous maneuvering and positioning hovering capabilities. The multi-rotor flight control system 50 can be automatically controlled by the flight control algorithm carried by the control module 40, or it can be automatically controlled by an independent control module, and the utility model does not limit this. Through the multi-rotor flight control system, the aerostat can be flexibly maneuvered in multiple degrees of freedom. The multi-rotor power system is electrically connected to a power supply and is powered by the power supply.

Among them, the horizontally oriented rotors are used to provide horizontal thrust, and the vertically oriented rotors are used to provide vertical thrust. The utility model has no special requirements on the number of horizontally oriented rotors and vertically oriented rotors. Common arrangements include 4 horizontally oriented rotors + 4 vertically oriented rotors or 4 horizontally oriented rotors + 2 vertically oriented rotors. The fewer the number of rotors, the higher the complexity of the flight control algorithm for the rotors.

[0040] In other embodiments of the utility model, the multi-rotor flight control system 50 includes a tiltable rotor and a vertically oriented rotor, and the tiltable rotor and the vertically oriented rotor are alternately arranged on the circumference of the airbag body 10. Among them, the tiltable rotor is used to provide horizontal thrust or vector thrust, and the vertically oriented rotor is used to provide vertical thrust. The utility model has no special requirements on the number of tiltable rotors and vertically oriented rotors. A common setting is 2 tiltable rotors + 2 vertically oriented rotors. The flight control algorithm of the tiltable rotor is more complex than that of the horizontally oriented rotor.
