Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV with a flip-up control surface. Background Technology
[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. The term "UAV" is actually a general term for unmanned aerial vehicles. UAVs can complete complex aerial flight missions and various payload tasks under unmanned conditions and are considered "aerial robots." The future development trend of UAVs will continue to move towards intelligence, autonomy, and diversification. Commercial applications will further expand, autonomous flight technology will gradually mature, and the application scenarios for diverse UAVs will continue to increase. The integration of UAVs and the Internet of Things (IoT) will contribute to the construction of smart cities, and the large-scale application of UAVs will achieve further breakthroughs. In general, as a high-tech product, UAVs are constantly developing and improving, playing a role in more fields and bringing more value to society. Control surfaces refer to aerodynamic wing surfaces that utilize deflection in airflow to generate balancing and control forces to manipulate flight. Currently, the control surfaces used in mainstream small UAVs are processed as a single unit with the wings and tail.
[0003] When the control surfaces of a drone are damaged during use, the ailerons or tail fins need to be completely removed and replaced, which increases maintenance costs and is more complicated, resulting in longer repair times. Utility Model Content
[0004] This invention provides a flip-up control surface for a drone. A motor drives one of the synchronous pulleys to rotate, and a synchronous belt drives another synchronous pulley to rotate a bidirectional threaded rod. A limiting rod adjusts the position of two movable plates. Through the cooperation of a connecting piece and a connecting plate, a fixed block slides on the mounting box, disengaging from its mounting groove. The movable control surface is then removed from the mounting box and replaced with a new one. The mounting groove on the movable control surface is aligned with the mounting box. Adjusting the position of the two movable plates moves the fixed block into the mounting groove to secure the movable control surface. This design reduces maintenance costs and time by replacing a single movable control surface without replacing the ailerons or tail fins.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a flip-up control surface for a drone, comprising: a drone body; two fixed control surfaces, each fixedly connected at one end to an outer surface of the drone body; a disassembly mechanism comprising four sets, each set including a mounting box, a rotating component, an adjusting component, a moving component, and two sets of pushing components; one end of the mounting box being rotatably embedded in an outer surface of the fixed control surface; the rotating component being disposed on the fixed control surface and the mounting box; the adjusting component being disposed within the mounting box; the moving component being disposed on the adjusting component; and each set of pushing components being disposed on the moving component; and two movable control surfaces, each movable control surface being disposed on the fixed control surface via the disassembly mechanism.
[0006] Furthermore, the rotating component includes a fixed motor, a fixed gear, and a transmission gear. The transmission gear is fixedly sleeved on the outer surface of the mounting box. The fixed motor is fixedly connected to the fixed rudder surface. The fixed gear is fixedly sleeved on the output end of the fixed motor, and the fixed gear and the transmission gear mesh with each other.
[0007] Furthermore, the adjustment component includes a mounting motor, two synchronous pulleys, and a bidirectional threaded rod. The bidirectional threaded rod is rotatably connected between the inner walls of both sides of the mounting box, and the mounting motor is fixedly connected to the lower inner wall of the mounting box. One of the synchronous pulleys is fixedly sleeved on the outer surface of the bidirectional threaded rod, and the other synchronous pulley is fixedly sleeved on the output end of the mounting motor. The two synchronous pulleys are mutually driven by a synchronous belt.
[0008] Furthermore, each of the moving components includes two limiting rods and two moving plates. The two limiting rods are fixedly connected between the inner walls of the two sides of the mounting box. Each moving plate is threaded onto the outer surface of the bidirectional threaded rod, and each moving plate is slidably fitted onto the outer surface of the two limiting rods.
[0009] Furthermore, each set of the pushing components includes four connectors, two connecting plates, and a fixing block. Two of the connectors are fixedly connected to the outer surface of one side of the two moving plates, and the other two connectors are fixedly connected to the bottom of the fixing block. Each connecting plate is rotatably connected between the two connectors, and each fixing block slides through the outer surface of the mounting box.
[0010] Furthermore, each of the active control surfaces has two mounting slots on one outer surface, and each mounting slot matches the mounting box. Each mounting slot has two fixing slots between its upper and lower inner walls, and each fixing slot matches two fixing blocks.
[0011] This invention provides a flip-up control surface for a drone. It offers the following advantages: The flip-up control surface is driven by a motor that rotates one of the synchronous pulleys. Through a synchronous belt, the other synchronous pulley rotates a bidirectional threaded rod. A limiting rod adjusts the position of two movable plates. The connecting piece and connecting plate work together to slide a fixed block on the mounting box, disengaging it from its mounting groove. The movable control surface is then removed from the mounting box, replaced with a new one, and its mounting groove is aligned with the mounting box. Adjusting the position of the two movable plates moves the fixed block into the mounting groove to secure the movable control surface. By replacing a single movable control surface without replacing the ailerons or tail fins, maintenance costs and time are reduced. Attached Figure Description

[0022] Specifically, the rotating components include a fixed motor 402, a fixed gear 403, and a transmission gear 404. The transmission gear 404 is fixedly sleeved on the outer surface of the mounting box 401. The fixed motor 402 is fixedly connected to the fixed rudder surface 2. The fixed gear 403 is fixedly sleeved on the output end of the fixed motor 402, and the fixed gear 403 and the transmission gear 404 mesh with each other.
[0023] In this embodiment: the fixed motor 402 is configured to provide rotational power, and the fixed gear 403 and the transmission gear 404 are configured for transmission. The fixed motor 402 rotates, causing the fixed gear 403 to rotate. The meshing of the fixed gear 403 and the transmission gear 404 causes the transmission gear 404 to drive the mounting box 401 to rotate. The mounting box 401 drives the movable rudder surface 3 to rotate. The principle and structure of the fixed motor 402 are common knowledge to those skilled in the art and will not be described in detail here. Its model can be selected according to the actual use.
[0024] Specifically, the adjusting components include a mounting motor 405, two synchronous pulleys 406, and a bidirectional threaded rod 407. The bidirectional threaded rod 407 is rotatably connected between the inner walls of both sides of the mounting box 401. The mounting motor 405 is fixedly connected to the lower inner wall of the mounting box 401. One synchronous pulley 406 is fixedly sleeved on the outer surface of the bidirectional threaded rod 407, and the other synchronous pulley 406 is fixedly sleeved on the output end of the mounting motor 405. The two synchronous pulleys 406 are mutually driven by a synchronous belt.
[0025] In this embodiment: the motor 405 is configured to provide rotational power, the two synchronous pulleys 406 are configured for transmission, and the outer surface of the bidirectional threaded rod 407 has two opposite threads. The principle and structure of the motor 405 are common knowledge to those skilled in the art and will not be described in detail here. Its model can be selected according to the actual use.
[0026] Specifically, each moving component includes two limiting rods 408 and two moving plates 409. The two limiting rods 408 are fixedly connected between the inner walls of the two sides of the mounting box 401. Each moving plate 409 is threaded onto the outer surface of the bidirectional threaded rod 407, and each moving plate 409 is slidably sleeved on the outer surface of the two limiting rods 408.
[0027] In this embodiment: the two limiting rods 408 are set for limiting, the two moving plates 409 are respectively located on two different threads of the bidirectional threaded rod 407, and are used to adjust the position of the two moving plates 409. The two pushing components are set on the two moving plates 409.
[0028] Specifically, each set of pushing components includes four connectors 410, two connecting plates 411, and a fixing block 412. Two connectors 410 are fixedly connected to one side of the outer surface of the two moving plates 409, and the other two connectors 410 are fixedly connected to the bottom of the fixing block 412. Each connecting plate 411 is rotatably connected between the two connectors 410, and each fixing block 412 slides through the outer surface of the mounting box 401.
[0029] In this embodiment: the four connectors 410 are used to connect the two connecting plates 411, and the fixing block 412 can slide on the mounting box 401 to fix the movable rudder surface 3.
[0030] Specifically, each movable control surface 3 has two mounting slots 5 on one outer surface, and each mounting slot 5 matches the mounting box 401. Each mounting slot 5 has two fixing slots 6 between its upper and lower inner walls, and each fixing slot 6 matches two fixing blocks 412.
[0031] In this embodiment: the mounting slot 5 is provided for docking the mounting box 401, and the fixing slot 6 is provided for fixing the block 412, thereby installing the movable rudder surface 3.
[0032] In use, the fixed motor 402 is turned on, causing the fixed gear 403 to rotate. The meshing of the fixed gear 403 and the transmission gear 404 causes the transmission gear 404 to rotate the mounting box 401, which in turn rotates the movable control surface 3. This generates balancing and control forces in the airflow to maneuver the flight. When the control surface is damaged, the mounting motor 405 is turned on, causing one of the synchronous pulleys 406 to rotate. Through the synchronous belt, the other synchronous pulley 406 rotates the bidirectional threaded rod 407. The rotation is controlled by the limiting rod 408. The positions of the two movable plates 409 are adjusted, and the fixed block 412 slides on the mounting box 401 through the cooperation of the connector 410 and the connecting plate 411, so that the fixed block 412 is disengaged from the fixed groove 6. Then, the movable control surface 3 is removed from the mounting box 401 and replaced with a new movable control surface 3. The fixed groove 6 on the movable control surface 3 is aligned with the mounting box 401. The positions of the two movable plates 409 are adjusted so that the fixed block 412 moves and aligns with the mounting groove 5 to fix the movable control surface 3. Without replacing the aileron and tail, the maintenance cost and maintenance time are reduced by replacing a single movable control surface 3.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
