Description

Technical Field

[0001] This utility model relates to the field of fixed-wing drone technology, and in particular to a foldable fixed-wing drone. Background Technology

[0002] Fixed-wing drones are designed similarly to traditional aircraft. Their flight principle involves generating forward thrust or pull through a power unit, while relying on the fixed wings of the fuselage to generate lift. This design allows them to generate greater lift than rotary-wing drones while consuming the same amount of energy, resulting in higher flight efficiency, faster cruising speed, and superior aerodynamic performance.

[0003] Currently, while fixed-wing UAVs have significant advantages in flight time and speed, their structural design still generally suffers from inherent limitations in portability. Most existing products adopt a rigid, integrated wing and tail configuration, which, while ensuring aerodynamic efficiency and structural strength during flight, results in a large overall size, making effective storage difficult when not in mission mode. This limitation requires a significant amount of space for transportation and storage, which is particularly unfavorable for field operations. Furthermore, the large packaging requirements increase logistics costs and operational complexity. Therefore, we propose a foldable fixed-wing UAV to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable fixed-wing drone.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foldable fixed-wing unmanned aerial vehicle (UAV) includes a fuselage. A T-shaped column is fixedly connected to the top of the fuselage. A wing is rotatably fitted onto the outer wall of the T-shaped column. Two connecting sleeves are fixedly connected to the outer wall of the fuselage. A threaded column is fixedly connected to the top of each of the two connecting sleeves. A lifting sleeve is threaded onto the outer wall of each of the two threaded columns. A positioning column is fixedly connected to the top of each of the two lifting sleeves. Two positioning holes are opened at the bottom of the wing. A sliding sleeve is fixedly connected to the inner wall of each of the two connecting sleeves. A sliding column is slidably connected to the inner wall of each of the two sliding sleeves. A telescopic rod is fixedly connected to one end of each of the two sliding columns. A telescopic component is provided on the outer wall of the telescopic rod.

[0007] Preferably, the telescopic assembly includes two fastening caps, the outer walls of the two telescopic rods are slidably connected to the inner walls of the two fastening caps, the inner walls of the two fastening caps are threadedly connected to the outer walls of the two sliding sleeves, and hollow rubber rings are fixedly connected to the inner walls of the two fastening caps. The rubber rings utilize their elastic deformation characteristics to play a "flexible fixing" role. When the fastening caps are pushed, the rubber rings can tightly squeeze the outer walls of the telescopic rods, and firmly fix the telescopic rods through friction, preventing slippage during flight.

[0008] Preferably, a motor is fixedly connected to the outer wall of the fuselage, and a propeller is fixedly connected to the outer wall of the motor output shaft. The motor drives the propeller to rotate through the output shaft, which can convert electrical energy (or other energy) into mechanical power.

[0009] Preferably, the inner walls of the two positioning holes are slidably connected to the outer walls of the two positioning posts, respectively.

[0010] Preferably, one end of each of the two telescopic rods is fixedly fitted with an accessory, and the outer walls of the two accessories are fixedly connected to the same tail fin, so that the aircraft can balance its flight attitude by adjusting its own angle (or by using the airflow) during flight.

[0011] Preferably, the inner wall of the rubber ring is pressed against the outer wall of the telescopic rod.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This design features a foldable and retractable structure. When not in use, the wings can be rotated to align with the fuselage, and the tail extension rod can be retracted into a sliding sleeve, significantly reducing the overall length and width of the aircraft. This eliminates the need for extensive space during transportation and storage. Furthermore, while achieving portability, it fully preserves the aerodynamic efficiency and structural strength of a traditional rigid layout, ensuring stability and reliability during flight.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Depend on Figures 1-4 As shown, a foldable fixed-wing drone is disclosed, including a fuselage 1. A motor 2 is fixedly connected to the outer wall of the fuselage 1, and a propeller 3 is fixedly connected to the outer wall of the output shaft of the motor 2. The motor 2 drives the propeller 3 to rotate through the output shaft, which can convert electrical energy (or other energy) into mechanical power to provide the thrust or lift required for the flight of the fuselage 1 (the number of motors 2 and propellers 3 can be increased). Existing electronic equipment and lithium batteries are installed inside the fuselage 1, and the whole is equipped with an existing compatible remote controller.

[0022] A T-shaped column 4 is fixedly connected to the top of the fuselage 1. A wing 5 is rotatably fitted on the outer wall of the T-shaped column 4. The T-shaped column 4 serves as the pivot point for the rotation of the wing 5, allowing the wing 5 to rotate flexibly around its outer wall.

[0023] Two connecting sleeves 6 are fixedly connected to the outer wall of the fuselage 1. Threaded posts 8 are fixedly connected to the top of each connecting sleeve 6. Lifting sleeves 9 are threaded onto the outer walls of each threaded post 8. Positioning posts 10 are fixedly connected to the top of each lifting sleeve 9. The inner walls of the two positioning holes are slidably connected to the outer walls of the two positioning posts 10. When the lifting sleeve 9 rotates, it can move up and down along the outer wall of the threaded post 8, converting its own rotational motion into linear movement of the positioning post 10. This controls the insertion or withdrawal of the positioning post 10 into the positioning hole, thus achieving the switching of the fixed state of the wing 5.

[0024] Two positioning holes are provided at the bottom of the wing 5. Sliding sleeves 7 are fixedly connected to the inner walls of the two connecting sleeves 6. Sliding columns 11 are slidably connected to the inner walls of the two sliding sleeves 7. The sliding sleeves 7 ensure that the sliding columns 11 drive the telescopic rod 12 to extend and retract in a straight line, so as to prevent the tail wing 14 from deviating when it moves.

[0025] One end of each of the two sliding columns 11 is fixedly connected to a telescopic rod 12. When not in use, the telescopic rod 12 can retract into the sliding sleeve 7 along with the sliding column 11, greatly reducing the overall length of the machine and improving portability. When in use, it can be pulled out from the sliding sleeve 7 and supported by the mounting bracket 13 to maintain the working position of the tail wing 14. One end of each of the two telescopic rods 12 is fixedly fitted with the mounting bracket 13, and the outer wall of the two mounting brackets 13 is fixedly connected to the same tail wing 14.

[0026] The outer wall of the telescopic rod 12 is provided with a telescopic assembly, which includes two fastening caps 15. The outer walls of the two telescopic rods 12 are slidably connected to the inner walls of the two fastening caps 15, and the inner walls of the two fastening caps 15 are threadedly connected to the outer walls of the two sliding sleeves 7. Hollow rubber rings 16 are fixedly connected to the inner walls of the two fastening caps 15. The inner walls of the rubber rings 16 are pressed against the outer walls of the telescopic rods 12. When the fastening caps 15 are rotated to the right, they move to the right along the sliding sleeves 7, releasing the pressure on the rubber rings 16 and allowing the telescopic rods 12 to extend and retract. When they are rotated to the left, they move to the left along the sliding sleeves 7, pushing the rubber rings 16 to deform and press against the telescopic rods 12, thereby fixing the position of the telescopic rods 12.

[0027] Working principle: When folding the wing 5, rotating the two lifting sleeves 9 causes them to move downwards via the two threaded posts 8. The downward movement of the threaded posts 8 drives the two positioning posts 10 downwards, allowing them to slide out of the two positioning holes, thus releasing the fixation on the wing 5. The wing 5 then rotates around the T-shaped post 4, aligning it with the fuselage 1. Rotating the two fastening caps 15 causes them to move to the right along the two sliding sleeves 7, releasing the fixation on the two telescopic rods 12. The tail fin 14 can then be moved along the two sliding posts 11 and the two sliding sleeves 7 via the two telescopic rods 12, retracting the telescopic rods 12 into the sliding sleeves 7, reducing the overall length and width, and facilitating movement. When in use, rotate the wing 5 to make it perpendicular to the fuselage 1, rotate the two lifting sleeves 9 to move the positioning pins 10 upward through the threaded pins 8, and the two positioning pins 10 move upward and press into the two positioning holes, thereby fixing the wing 5 to the top of the fuselage 1, and pull the tail fin 14 outward to make the two telescopic rods 12 slide out from the two sliding sleeves 7. After they are completely pulled out, rotate the two fastening caps 15 to move them to the left along the two sliding sleeves 7. After the fastening caps 15 move a certain distance, the rubber ring 16 is pushed by the fastening caps 15 and deforms to press against the outer wall of the telescopic rod 12, so that the telescopic rod 12 is fixed in the fastening caps 15, and then fixed in the sliding sleeves 7.

[0028] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
