[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0028] In order to enable the aerostat to obtain the same display capability as the ground robots in shopping malls, hotels, restaurants, etc. which are becoming popular, the utility model forms LED lamp beads into an array, and attaches and fixes the LED lamp bead array to the surface of the airbag of the aerostat by bonding, riveting, etc., to realize an aerostat with display capability that can play text, pictures or video images.

[0029] like Figure 1 As shown, an embodiment of the utility model provides an aerial imaging aerostat, which includes an airbag body 10 , a display device 20 , and a control module 30 .

[0030] The display device 20 is disposed at the bottom or side of the airbag body 10 , and the contact portion between the airbag body 10 and the display device 20 is a flat surface.

[0031] In actual flight in the real world, in order to ensure the safety of the aerostat itself and to stay away from areas that people may physically reach, the aerostat usually floats at a certain height of at least 3 meters, and the audience on the ground usually needs to look up. The embodiment of the utility model uses an LED lamp bead array attached to the bottom or side of the aerostat as a display screen. In order to obtain a better viewing effect, when the LED lamp bead array is set at the bottom of the aerostat, the aerostat is controlled to float at a higher altitude; when the LED lamp bead array is set on the side of the aerostat, the aerostat is controlled to float at a lower altitude.

[0032] The embodiment of the utility model has no particular restrictions on the shape of the airbag body. Figure 1 As shown, in some embodiments of the utility model, the airbag body is shaped like a sphere with a portion of the bottom cut off, and a display device is provided at the bottom cross section. In other embodiments of the utility model, the airbag body is a cube, and a display device is provided at the bottom of the cube. In some other embodiments, the airbag body is a cube, and a display device is provided on two opposite sides of the cube. In some other embodiments, the airbag body is a cylinder or a drum-shaped body that is flat up and down, and a display device is provided on the flat bottom surface.

[0033] like Figure 2 As shown, the display device 20 includes a conductive adhesive layer 21 , an LED lamp bead array layer 22 , and a protective film layer 23 which are sequentially arranged from the inside to the outside along the flat surface of the airbag body 10 .

[0034] The conductive adhesive layer 21 is a conductive adhesive coating, and the conductive adhesive layer 21 is disposed on the flat surface of the airbag body 10. The conductive adhesive helps to maintain good contact between the LED lamp bead array layer 22 and the surface of the airbag body 10 and provide electrical connection. Common conductive adhesives include silver paste conductive adhesive, copper paste conductive adhesive, carbon paste conductive adhesive, etc.

[0035] The LED lamp bead array layer 22 is bonded to the flat surface of the airbag body 10 through the conductive adhesive layer 21; the LED lamp bead array layer 22 includes an LED lamp bead array. The LED lamp bead array is a single-chip LED lamp bead array or a multi-chip LED lamp bead array. The size and shape of the LED lamp bead array are adapted to the size and shape of the position to be installed of the airbag body 10. The LED lamp bead array should be soft and damage-resistant to adapt to the inflation and deflation process of the airbag. The LED lamp beads are connected to each other through a circuit with a certain flexibility. A circuit that is too light and soft is not damage-resistant enough, and a circuit that is too strong and damage-resistant is too heavy. It is necessary to select an LED lamp bead array with appropriate weight and flexibility.

[0036] In some embodiments of the utility model, conductive adhesive is applied to the positions corresponding to the pins of the LED lamp bead array on the airbag body 10, and the non-pin parts of the LED lamp bead array are also fixedly bonded to the airbag body 10 by non-conductive adhesive. In other embodiments of the utility model, conductive adhesive is applied to the positions corresponding to the pins and the central part of the LED lamp bead array on the airbag body 10, and the other parts of the LED lamp bead array are also fixedly bonded to the airbag body 10 by non-conductive adhesive. The non-conductive adhesive includes adhesive and hot melt adhesive. By fixing and bonding the airbag with the non-conductive adhesive, the LED lamp bead array is firmly fixed to the airbag body and will not fall off when the airbag body is inflated or deflated.

[0037] In some embodiments of the utility model, the LED lamp bead array is also fixed to the airbag body 10 by riveting. The airbag body 10 is provided with a plurality of fixing holes for fixing external devices. The LED lamp bead array is fixed to the airbag body 10 through the fixing holes by rivets, bolts or other structural members, so that the connection between the LED lamp bead array and the airbag body 10 is more firmly established.

[0038] The protective film layer 23 covers the surface of the LED lamp bead array layer 22, and is used to protect the LED lamp bead array layer 22 from damage by the external environment; the protective film layer 23 is a transparent protective film. The protective film layer 23 is fixed to the LED lamp bead array layer 22 by a transparent adhesive. The protective film layer 23 mainly plays the role of waterproof, dustproof and windproof. The protective film layer 23 should be soft and durable to adapt to the movement and deformation of the airbag. Its material can be a transparent plastic film or other transparent material that is both soft and durable. The area of ​​the protective film is larger than that of the LED lamp bead array layer 22, so that the center and edge of the LED lamp bead array layer 22 are adequately protected. After the protective film layer 23 is bonded to the LED lamp bead array layer 22 by an adhesive, it can be fixed to the airbag body 10 by riveting to prevent it from falling off.

[0039] The control module 30 is electrically connected to the LED lamp array to control the LED lamp array to display images. The control module 30 can be connected to a ground system or a cloud system by wireless connection to control the playback content in real time.

[0040] In some embodiments of the present invention, the aerostat further includes a multi-rotor power system 40 .

[0041] In order to provide flight maneuverability, the embodiment of the utility model provides a multi-rotor power system 40 on the aerostat, which is distributedly installed on the circumference of the airbag body 10 of the aerostat.

[0042] like Figure 3 As shown, in some embodiments of the utility model, the airbag body 10 is drum-shaped, and the multi-rotor power system 40 includes a horizontally oriented rotor 41 and a vertically oriented rotor 42, and the horizontally oriented rotor 41 and the vertically oriented rotor 42 are alternately arranged on the circumference of the airbag body 10. Among them, the horizontally oriented rotor 41 is used to provide horizontal thrust, and the vertically oriented rotor 42 is used to provide vertical thrust.

[0043] like Figure 4 As shown, in other embodiments of the present invention, the airbag body 10 is drum-shaped, and the multi-rotor power system 40 includes a tiltable rotor 43 and a vertically oriented rotor 42, and the tiltable rotor 43 and the vertically oriented rotor 42 are alternately arranged on the circumference of the airbag body 10. The tiltable rotor 43 is used to provide horizontal thrust or vector thrust, and the vertically oriented rotor 42 is used to provide vertical thrust.

[0044] The utility model has no particular restriction on the number of rotors. In practical applications, combinations such as 4 horizontal rotors 41 + 4 vertical rotors 42, 4 horizontal rotors 41 + 2 vertical rotors 42, 2 tiltable rotors 43 + 2 vertical rotors 42, etc. can be used.

[0045] When the display device 20 is arranged on the side of the airbag body 10, the position of the rotor in the multi-rotor power system 40 should avoid the display device 20, so as not to block the image displayed on the bottom of the airship, and provide omnidirectional maneuverability, so that the airship can translate in any degree of freedom up, down, left, right, front and back, breaking away from the traditional airship that can only move along the axis of the hull and rely on various stabilizer turning maneuvers. This is beneficial to the commercial value of displaying image advertisements and is particularly suitable for use in relatively small indoor spaces.

[0046] In some embodiments of the present invention, the preparation process of the image aerostat is as follows:

[0047] (1) Preparation of the airbag body: The airbag body is usually prepared by heat-sealing and welding multiple pieces of the airbag material. During the preparation process, it is necessary to ensure that the surface of the airbag is clean and flat, and there are no sharp objects or impurities to ensure its smoothness and adhesion.

[0048] (2) LED array layout: Select a suitable LED array to ensure that its size and shape are suitable for the surface of the airbag body. The LED array should be flexible and resistant to damage to adapt to the inflation and deflation process of the airbag. Select an LED array with moderate flexibility and resistance to damage. Select one or more LED arrays based on the size and number of display areas.

[0049] (3) Applying conductive adhesive: Apply the conductive adhesive evenly on the surface of the airbag body.

[0050] (4) Install the LED lamp array: Place the LED lamp array slowly and evenly on the surface of the airbag body coated with the conductive adhesive. Ensure that the LED lamp array is in full contact with the conductive adhesive and maintains a stable installation position.

[0051] (5) Adhesive fixation: Use a suitable non-conductive adhesive to fix the LED lamp array on the surface of the airbag body.

[0052] (6) Riveting fixation: Use a rivet-like structural member to fix the LED lamp array to the airbag body.

[0053] (7) Coating protection: A layer of transparent protective film is covered on the LED lamp bead array, and the protective film is fixed to the LED lamp bead array layer by a transparent adhesive.

[0054] (8) Power and control module installation: Install the power system and control module at the pre-set positioning holes on the airbag body, and adjust the position, direction angle and control parameters of the rotor in the power module according to the position of the LED array.

[0055] The utility model has the following beneficial effects: the utility model sets a display device on the flat surface of the bottom or side of the airbag body of the aerostat, and the display device includes a conductive adhesive layer, an LED lamp bead array layer, and a protective film layer arranged in sequence from the inside to the outside along the airbag body, and the LED lamp bead array is controlled by a control module to display images. The image display system of the utility model has a simple structure, light weight, low cost, and can achieve good advertising and marketing effects.

[0056] In addition, the multi-rotor power system provides the airship with flexible flight maneuverability, which is more conducive to displaying the commercial value of image advertising and is more advantageous than traditional airships when used in relatively small indoor spaces.

[0057] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms of deformation without departing from the scope of protection of the utility model and the claims, which all fall within the protection of the utility model.
