Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of low-altitude unmanned aerial vehicles, in particular to a new energy disc-shaped aerostat. BACKGROUND

[0002] In recent years, low-altitude unmanned aerial vehicles (UAVs) have been widely used in fields such as logistics transportation, agricultural plant protection, emergency rescue, urban air mobility (UAM), etc. due to their flexibility and versatility. Among them, multi-rotor aircrafts have become the mainstream configuration in the market because of their simple structure, strong vertical take-off and landing (VTOL) capability, and convenient control.

[0003] Traditional multi-rotor aircrafts use open propeller design, which can easily cause collision risks to surrounding people and objects when the propeller rotates at high speed, and the safety hazards are prominent. In addition, the open propeller produces strong aerodynamic noise (usually more than 80 decibels) when rotating at high speed, especially when flying at low altitude, causing noise pollution to urban residential areas. Limited by battery energy density and aerodynamic efficiency, the endurance time of multi-rotor aircrafts is generally less than 30 minutes, the effective payload is usually 20%-30% of its own weight, and the inherent defects of high hovering energy consumption result in short range and small task radius, making it difficult to meet the demand for long-distance operation.

[0004] Therefore, there is an urgent need for a new type of new energy disc-shaped aerostat to provide an effective solution to the defects of the prior art. SUMMARY

[0005] The present application aims to provide a new energy disc-shaped aerostat to solve the problems raised in the background art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution:

[0007] A new energy disc-shaped aerostat, comprising a disc-shaped shell, a gas bag and a ducted fan:

[0008] The disc-shaped shell is a flat disc structure, and the gas bag is filled in the interior of the disc-shaped shell. The gas bag includes two or more independent gas bags. At least one gas bag is filled with helium, and the helium in the gas bag provides lift for the aerostat. At least one gas bag is filled with air, which can adjust the volume of the gas bag by filling or emptying air, and then control the lifting of the aerostat by changing the volume of the gas bag. Eight ducts are arranged in the gas bag, which are evenly distributed in the front, back, left and right directions. The inner ends of the eight ducts are connected, and the outer ends are connected to the outside of the gas bag. Each duct is provided with a ducted fan, and the eight ducted fans cooperatively control the movement of the aerostat in the horizontal direction. The disc-shaped shell is also provided with an energy module, a flight control module and a signal transmission module.

[0009] Further, the disc-shaped shell comprises an upper shell and a lower shell, the center of the air bag is provided with a hollow cabin, the upper shell is provided with an upper convex arc-shaped dome above the cabin, the arc-shaped dome is provided with an upper observation window in an annular array, the lower shell is provided with a lower convex arc-shaped dome below the cabin, the arc-shaped dome is provided with a lower observation window in an annular array, and the lower shell is provided with an exhaust port at the outer end port of the duct.

[0010] Further, the lower observation window is an open structure, and the air intake can be increased after being opened.

[0011] Further, the disc-shaped shell uses aluminum alloy or carbon fiber as a skeleton, and the skeleton is coated with a flexible skin.

[0012] Further, the air bag comprises an inner air bag, a middle air bag and an outer air bag, which are all annular structures, the middle air bag and the inner air bag are filled with helium, and the outer air bag is filled with air.

[0013] Further, the top of the disc-shaped shell is covered with a solar thin film battery, and the inside is loaded with a hydrogen fuel cell or a high-density lithium battery pack.

[0014] Further, the disc-shaped shell is loaded with a high-definition camera, an infrared sensor and an air quality detector.

[0015] Further, the bottom of the disc-shaped shell is provided with an openable cargo hold for carrying small goods.

[0016] Compared with the prior art, the beneficial effects of the present application are:

[0017] 1. The disc-shaped main body adopts a flat disc structure, the helium air bag provides basic lift for the airship, and the air air bag controls the airship to ascend and descend by filling and discharging air. When the air air bag discharges air, the mass of the airship decreases, and the ascending operation is realized; when the air air bag fills air, the mass of the airship increases, and the descending operation is realized. Since the buoyancy counteracts the gravity, the duct fan only needs to provide a small amount of balanced thrust, greatly reducing the energy consumption and greatly improving the endurance time. Eight duct fans realize multi-degree-of-freedom motion through differential thrust, improving the maneuverability and wind resistance performance.

[0020] 4、The present application divides the air bag into three independent chambers, so as to prevent the overall failure caused by the damage of a single air bag and ensure safety redundancy.

[0021] 5、The present application realizes long endurance and high performance by combining multiple energy sources. BRIEF DESCRIPTION OF DRAWINGS

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Embodiment 1: Please refer to Figures 1-6 A new energy disc-shaped aerostat, comprising a disc-shaped shell, an air bag 8 and a ducted fan 11:

[0031] The disc-shaped shell has a flat, circular structure. Airbags 8 are filled inside the disc-shaped shell, and each airbag 8 includes at least two independent airbags. At least one airbag is filled with helium, which provides lift for the airship. At least one airbag is filled with air, and its volume can be adjusted by inflating or deflating the airbag, thereby controlling the airship's ascent and descent. Each airbag 8 contains eight ducts 9, evenly distributed in the front, back, left, and right directions. The inner ends of the eight ducts 9 are connected, and their outer ends lead to the outside of the airbag 8. Each duct 9 is equipped with a duct fan 11, and the eight duct fans 11 work together to control the airship's horizontal movement in all directions. The disc-shaped shell also contains an energy module, a flight control module, and a signal transmission module.

[0032] The disc-shaped housing is equipped with a high-definition camera, an infrared sensor, and an air quality detector.

[0033] The bottom of the disc-shaped hull has an openable cargo compartment for carrying small goods.

[0034] Working principle of this embodiment:

[0035] This embodiment utilizes airship combined with UAV flight control technology to achieve low-energy, high-maneuverability flight of the unmanned aerial vehicle. For example... Figure 3 , Figure 4 As shown, helium gasbags provide the basic lift for the airship, while airbags control its ascent and descent through inflation and deflation: when airbags deflate, the airship's mass decreases, enabling ascent; when airbags refill, the airship's mass increases, enabling descent. This process consumes extremely little energy, significantly better than the energy consumption of traditional multi-rotor active hovering. Buoyancy counteracts most of the gravity, and the ducted fan only needs to provide a small amount of balancing thrust, greatly reducing energy consumption and significantly increasing endurance.

[0036] like Figure 1 As shown, compared to traditional long, cylindrical airships, the flat, disc-shaped structure of this embodiment has the following advantages: strong wind resistance; the disc-shaped design with a 360-degree windward surface is unaffected by crosswinds, easy to maneuver, and can cope with complex and changeable weather conditions; its stability is superior to airships, and its maneuverability is stronger; the larger surface area of ​​the disc allows for the installation of solar thin films, enabling low-carbon flight and longer endurance; the concept of a disc is aesthetically pleasing and has inherent appeal, making it more suitable for cultural and tourism promotion. Furthermore, traditional airships suffer from difficult takeoffs and landings, poor rudder efficiency, and poor maneuverability—long-standing problems; while the new energy disc proposed in this embodiment combines UAV flight control technology, resulting in more stable and convenient takeoffs and landings.

[0037] like Figure 3As shown, 8 groups of ducted fans realize multi-degree of freedom horizontal movement through differential thrust. When moving forward or backward, the two groups of ducted fans in front and back increase or decrease speed to generate thrust difference, and when turning, the diagonal ducted fans generate torque through reverse thrust. When working, it can realize wind-resistant stable posture, and real-time adjust the rotating speed of each ducted fan to offset wind disturbance, and combine with flight control algorithm to keep stable. Since the inner ends of the eight ducts 9 are connected, the duct 9 where the non-working ducted fan is located can be used as an air inlet hole, so the airship can ensure air intake in the closed state, and the upper and lower closed structure can improve the flight safety of the device.

[0038] As shown in Figures 1-3 , the closed design of the ducted fan avoids exposing the blades and reduces the risk of collision; the buoyancy hovering reduces the probability of power failure and falling. The duct structure suppresses vortex noise and is suitable for urban low-altitude operation.

[0039] In this embodiment, a high-definition camera, an infrared sensor, an air quality detector, and an openable cargo hold are mounted on the disc-shaped shell, which can be applicable to video shooting, environmental detection, urban logistics and other fields.

[0040] Embodiment 2: Please refer to Figure 1 and 4 ~6, a new energy disc-shaped airship, which is different from embodiment 1 in that the disc-shaped shell comprises an upper shell 1 and a lower shell 4, the center of the air bag 8 is provided with a hollow cabin 10, the upper shell 1 is provided with an upper convex arc-shaped dome 2 above the cabin 10, the arc-shaped dome 2 is arranged in a ring array with upper observation windows 3, the lower shell 4 is provided with a lower convex arc-shaped dome 6 below the cabin 10, the arc-shaped dome 6 is arranged in a ring array with lower observation windows 7, and the lower shell 4 is provided with an exhaust port 5 at the outer end of the duct 9.

[0041] The lower observation window 7 is an openable structure, which can increase the air intake after being opened.

[0042] In this embodiment, the hollow cabin 10 can be used for carrying objects or people, and the upper observation window 3 and the lower observation window 7 facilitate observation or appreciation of the external environment. When the lower observation window 7 is provided as an openable structure, it can increase the air intake after being opened, thereby improving the working efficiency of the ducted fan.

[0043] Embodiment 3: A new energy disc-shaped airship, which is different from embodiment 1 in that the disc-shaped shell uses aluminum alloy or carbon fiber as the skeleton, and the skeleton is coated with a flexible skin.

[0044] In this embodiment, aluminum alloy or carbon fiber is used as the skeleton to ensure the strength of the shell, and the flexible skin is used to ensure the sealing of the shell and reduce wind resistance, so that the lightweight structure can ensure the structural performance.

[0045] Embodiment 4: Please refer to Figure 4A new energy dish-shaped aerostat, which is different from the embodiment 1 in that the gas bag 8 comprises an inner gas bag 14, a middle gas bag 13 and an outer gas bag 12, all of which are annular structures, the middle gas bag 13 and the inner gas bag 14 are filled with helium, and the outer gas bag 12 is filled with air.

[0046] In this embodiment, the gas bag 8 is divided into three independent chambers, which can prevent the overall failure caused by the damage of a single gas bag and ensure the safety redundancy. In particular, the independent helium chamber is provided as at least two, which can reduce the risk of falling caused by helium leakage.

[0047] Embodiment 5: A new energy dish-shaped aerostat, which is different from the embodiment 1 in that the top of the dish-shaped shell is covered with a solar thin film battery, and a hydrogen fuel cell or a high-density lithium battery pack is carried inside.

Solar energy is used as a supplementary energy source, and the thin film solar cell is used to supplement the energy on sunny days. The high-density battery is used for short-time high-power output, such as emergency climbing or high-speed maneuvering.
