Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically to a modular flying wing vertical take-off and landing UAV with an attached biomimetic suction cup. Background Technology

[0002] Currently, mainstream drones are broadly categorized into two types: fixed-wing drones and multi-rotor drones. Generally speaking, drones capable of vertical takeoff and landing (VTOL) are multi-rotor drones, which can hover in the air for a certain period. VTOL aircraft are a technology that allows for takeoff and landing without a runway. In contrast, fixed-wing drones require a runway for takeoff, but their advantage lies in their relatively lower energy consumption due to the fixed wings. However, existing VTOL solutions suffer from low flight speeds, complex rotor systems, and large, complex airframes. Regarding the application of adsorption-equipped drones, some countries have already used them in military exercises for reconnaissance and demolition missions. While the flying-wing configuration of drones is relatively well-developed and mature, highly refined configurations for drones equipped with adsorption capabilities are less common.

[0003] Therefore, how to design a flying wing-shaped UAV that can perform vertical take-off and landing and also has an adsorption function for reconnaissance and patrol is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] Therefore, the purpose of this invention is to propose a modular flying wing vertical take-off and landing (VTOL) drone with an attached biomimetic suction cup, and to design a flying wing layout drone that meets the vertical take-off and landing function and can achieve the suction function for reconnaissance and patrol.

[0005] This invention provides a modular flying wing vertical takeoff and landing unmanned aerial vehicle (UAV) with an attached biomimetic suction cup, comprising:

[0006] The main body is streamlined.

[0007] The wing assembly has two sets of the wing assemblies symmetrically and detachably connected to both sides of the main body;

[0008] The wing assembly is connected to a tail fin device at the rear. The tail fin device is equipped with an adsorption component for temporary docking and adsorption. The adsorption component is remotely controlled via a Bluetooth module.

[0009] A servo assembly is installed on the outer side of each wing assembly;

[0010] An auxiliary connecting plate is provided, and each of the servo components is externally connected to the auxiliary connecting plate and drives the auxiliary connecting plate to rotate. The auxiliary connecting plate is L-shaped.

[0011] A power rotor assembly is mounted on the other side of the auxiliary connecting plate, with a propeller connected to the power rotor assembly. The two sets of power rotor assemblies rotate in opposite directions.

[0012] The system also includes a control component, which comprises a flight control integrated control system, a horizontal positioning system, and a current transmission system, and is installed inside the wing assembly and the main body. The flight control integrated control system is connected to each sub-control system through a main control board, and its main control board is wirelessly connected to the host computer.

[0013] Furthermore, the main body has bayonets on both sides, and the bayonets on both sides have the same structure, for connecting the wing assembly; its rear is open, which facilitates the extension of the tail wing device outward.

[0014] Furthermore, the two wing assemblies are integrated as a whole and arranged in a flying wing configuration, with a honeycomb structure on the upper side of the wing body; stiffeners are provided on the flat plate, and mounting platforms for installing the servo assemblies are provided on both sides; a chip slot is provided in the middle of the main body cabin, and an L-shaped tail fin device is connected to the rear of it.

[0015] Furthermore, chip slots are provided on both sides of the chip slot, and the chip slots are engaged with the inside of the host body.

[0016] Further, the adsorption component includes:

[0017] The adsorption servo motor body has one end connected to the tail fin device via a dual-axis short U-bracket; the Bluetooth module is mounted on the adsorption servo motor body.

[0018] A dual-axis wide U-shaped bracket is provided, with the other end of the adsorption servo motor body connected to the dual-axis wide U-shaped bracket via a virtual axis servo disk. The dual-axis wide U-shaped bracket has adsorption material for adsorption surface contact.

[0019] Furthermore, the adsorbent material is a nanogel.

[0020] Furthermore, the tail fin device has a connecting plate at its rear, and the connecting plate is provided with positioning holes to cooperate and fix with the dual-axis short U-bracket.

[0021] Furthermore, the L-shaped auxiliary connecting plate has fixing holes corresponding to the servo assembly and the power rotor assembly.

[0022] Furthermore, the propeller is fastened to the power rotor assembly by a nut.

[0023] Furthermore, when the main control board in the flight control integrated control system receives the start command, the horizontal positioning system determines the current horizontal status of the aircraft and coordinates with the initial rotation angle of the servo motor. The current transmission system supplies DC current to the servo motor assembly and the power rotor assembly. The flight control integrated system adjusts the direction and pulse signals according to the instructions sent by the host computer. If no next signal is received, the power rotor assembly and the servo motor assembly maintain their original state. If a reset signal is received, the servo motor assembly returns to the initial rotation angle, and the power rotor assembly stops rotating.

[0024] The adsorption component is remotely controlled via Bluetooth. When the main control board of the flight control integrated system receives the start command, it adjusts the initial angle of the adsorption component based on the horizontal information fed back by the horizontal positioning system, making it parallel to the adsorption surface. The host computer sends forward and reverse information commands, which can further adjust the angle position signal of the adsorption component, enabling the adsorption component to achieve the adsorption function.

[0025] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. This invention integrates fixed-wing and rotary-wing technologies into a vertical take-off and landing (VTOL) flying-wing configuration, combining the advantages of both. It can fly at high speeds like a fixed-wing aircraft, hover in the air like a rotary-wing aircraft, and even attach to objects. It boasts advantages such as low structural weight, simple operation, and high flight efficiency. Unlike existing quadcopter drones, this drone uses dual rotors to provide lift, significantly saving axial space, allowing for greater modularity, and increasing the drone's flexibility and speed.

[0027] 2. Compared with existing flying-wing drones, the dual-rotor design gives this drone the ability to take off and land vertically. Compared with the runways required by flying-wing drones, this drone is suitable for a wider range of occasions and can enter working status at any time in cities with high-rise buildings.

[0028] 3. The UAV is designed with a nano-adhesive adsorption device, which can meet the function of temporary docking when the UAV is performing a mission. After entering the adsorption state, the two power rotor components of the UAV can stop rotating, which greatly reduces energy consumption. At the same time, the design of the adsorption component can also greatly improve the stealth characteristics of the UAV when performing a mission.

[0029] 4. The use of a wireless module enables communication between the host computer and the main control board, significantly enhancing remote communication capabilities. Furthermore, the drone can incorporate various modular designs, maximizing its functionality. Therefore, it is suitable for diverse application environments and greatly reduces labor costs.

[0051] Specifically, the main body 1 has bayonets on both sides, and the bayonets on both sides have the same structure, which are used to connect the wing assembly 2; its rear is open, which facilitates the extension of the tail wing device outward.

[0052] See appendix Figure 3 In an embodiment of the present invention, the two wing assemblies 2 are integrated as a single unit, arranged in a flying wing configuration, with a honeycomb structure on the upper side of the wing body; mounting platforms 201 for installing the servo assembly 3 are located on both outer sides of the wing body; a chip slot 202 installed in the inner cabin of the main body 1 is located in the middle, and an L-shaped tail fin device 11 is connected to its rear.

[0053] Advantageously, chip slots are provided on both sides of the chip slot 202, and the chip slots engage with the interior of the main body 1 to achieve a detachable connection between the wing assembly 2 and the main body 1.
