Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a quick-release connection component for a compound-wing UAV. Background Technology

[0002] The development of drone technology and the market is generally showing a trend of diversification and rapid growth, and the commercial sales market is also expanding. However, with the continuous expansion of drone application scenarios, the market demand for high-performance and high-efficiency drones is increasing. Against this backdrop, compound-wing drones have emerged, riding the wave of the times, thanks to the continuous development of modern materials science, power systems, and automatic control technologies. A compound-wing drone is a design that combines the characteristics of fixed-wing and multi-rotor drones, aiming to reduce flight energy consumption, improve flight efficiency, and expand flight range by leveraging the advantages of two different flight principles. Compound-wing drones typically employ a fixed-wing aerodynamic design to achieve long-duration cruise flight, while combining rotors or other vertical take-off and landing devices for take-off, landing, and hovering in confined spaces.

[0003] Compound-wing UAVs are equipped with multiple fixed wings and multi-rotors to meet various flight requirements. In some existing compound-wing UAVs, the wings are generally fixedly connected to the fuselage, resulting in a large overall space occupation of the UAV. This not only increases the difficulty of transporting and handling the UAV, but also makes the wings more susceptible to damage during transportation, leading to increased maintenance costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing composite wing drones, where the wings and fuselage are generally fixedly connected, resulting in a large overall space occupation of the drone. This not only increases the difficulty of transporting and handling the drone, but also makes the wings prone to damage during transportation, leading to increased maintenance costs. The invention provides a quick-release connection component for composite wing drones.

[0005] The purpose of this utility model is achieved through the following technical solution: a quick-release connection component for a compound wing UAV, including a fuselage and a fixed wing mounted on the fuselage, with mounting seats installed on both sides of the fixed wing, and a detachable multi-rotor mounting bracket installed on the mounting seats;

[0006] The fuselage has slots on its inner top and bottom walls. A plug that matches the slots is provided on one side of the fixed wing. An installation tube is installed on the fuselage. A first lifting rod is installed inside the installation tube. A first lifting plate that is slidably connected to the installation tube is installed in the middle of the first lifting rod. The first lifting plate can be raised and lowered along the inner wall of the installation tube. A first spring is installed between the bottom of the first lifting plate and the inner bottom wall of the installation tube. The bottom of the first lifting rod extends into the fuselage and is fitted with a locking block. Locking blocks are installed on the inner top and bottom walls of the fixed wing. A first locking groove that matches the locking block is provided on one side of the locking block.

[0007] By setting up a first spring, a first lifting rod, and an installation tube, the first lifting rod and the first lifting plate can move up and down along the installation tube. When installing the fuselage and fixed wing, first press the first lifting rod to move the locking block closer to the middle of the fuselage. After the insert on the fixed wing is inserted into the slot on the fuselage, release the first lifting rod. At this time, the first lifting rod rises and resets under the action of the first spring and the first lifting plate, which drives the first locking groove on the locking block to insert and lock with the locking block on the fixed wing, completing the quick installation of the fuselage and fixed wing. When disassembling, press the first lifting rod again to release the locking block from the first locking groove on the locking block, completing the quick disassembly of the fixed wing.

[0008] The mounting base has a mounting slot, and a second lifting rod is installed on the mounting base, penetrating the mounting slot and extending into the mounting base. A second lifting plate is installed in the middle of the second lifting rod, which is slidably connected to the inner wall of the mounting slot. A second spring is installed between the bottom wall of the second lifting plate and the bottom wall of the mounting slot. One end of the multi-rotor mounting frame extends into the mounting base and has a second locking groove. The bottom of the second lifting rod is adapted to the second locking groove. When installing the multi-rotor mounting frame, first lift the second lifting rod to compress the second spring. After inserting the multi-rotor mounting frame into the mounting base, release the second lifting rod. When the second locking groove slides to the bottom of the second lifting rod, the second lifting rod extends into the second locking groove under the action of the second spring to complete the locking installation of the mounting base and the multi-rotor mounting frame. Disassembly is the same as the above operation, thereby realizing the quick installation and removal of the multi-rotor on the multi-rotor mounting frame, facilitating the transportation of the UAV, avoiding damage to the wings during transportation, and extending the service life of the UAV wings.

[0009] A further technical solution involves installing a rotating block on the upper part of the first lifting rod, providing a sliding groove on the inner wall of the mounting tube, and installing a slider on the first lifting plate that is slidably connected to the sliding groove. The mounting tube is rotatably connected to the machine body. This rotatable connection between the mounting tube and the machine body allows the first lifting rod to rotate via the rotating block. With the cooperation of the sliding groove and the slider, the mounting tube rotates to lock the block, thereby retracting the locking block into the machine body. This prevents damage to the locking block during transportation and ensures the service life of the equipment.

[0010] A further technical solution is to install a rotating rod on the first lifting rod and two sets of stops on the machine body. The stops are used to limit the rotation angle of the rotating rod and the first lifting rod by setting the stops, which facilitates the docking of the first locking groove on the locking block at the bottom of the first lifting rod with the locking block, thereby improving the installation efficiency of the equipment.

[0011] A further technical solution is that the end of the locking block furthest from the machine body is tapered. This tapered design facilitates the docking and installation of the locking block with the first locking groove.

[0012] A further technical solution is to install a pressing block on the upper part of the second lifting rod. By setting the pressing block, the second lifting rod can be easily lifted, improving the convenience of operation.

[0013] A further technical solution is that the joints of the fuselage, fixed wing, mounting base, and multi-rotor mounting frame are all hollow. This hollow joint design facilitates the connection of wiring and avoids unnecessary risks caused by exposed wiring.

[0014] This utility model has the following advantages: By setting a first spring, a first lifting rod, and a mounting tube in cooperation, the first lifting rod and the first lifting plate can move up and down along the mounting tube, driving the first locking groove on the locking block to engage and lock with the locking block on the fixed wing, thus completing the rapid installation of the fuselage and the fixed wing. When disassembling, pressing the first lifting rod again releases the locking block from the first locking groove on the locking block, completing the rapid disassembly of the fixed wing. Under the action of the second spring, the second lifting rod extends into the second locking groove to lock the mounting base and the multi-rotor mounting frame, thereby realizing the rapid installation and disassembly of the multi-rotor on the multi-rotor mounting frame, facilitating the disassembly and transportation of the UAV, avoiding damage to the wings during transportation, and extending the service life of the UAV wings.

[0027] The fuselage 1 has slots 14 on its inner top and bottom walls. The fixed wing 2 has a plug 15 on one side that matches the slot 14. The fuselage 1 is equipped with an installation tube 5. The installation tube 5 is equipped with a first lifting rod 6. The middle of the first lifting rod 6 is equipped with a first lifting plate 8 that is slidably connected to the installation tube 5. The first lifting plate 8 can be raised and lowered along the inner wall of the installation tube 5. A first spring 18 is installed between the bottom of the first lifting plate 8 and the inner bottom wall of the installation tube 5. The bottom of the first lifting rod 6 extends into the fuselage 1 and is equipped with a locking block 9. The fixed wing 2 has locking blocks 11 on its inner top and bottom walls. The locking block 9 has a first locking groove 10 on one side that matches the locking block 11.

[0028] By setting the first spring 18, the first lifting rod 6, and the mounting tube 5 in coordination, the first lifting rod 6 and the first lifting plate 8 can be raised and lowered along the mounting tube 5. When installing the fuselage 1 and the fixed wing 2, first press the first lifting rod 6 to move the locking block 9 closer to the middle of the fuselage 1. After the insertion block 15 on the fixed wing 2 is inserted into the slot 14 on the fuselage 1, release the first lifting rod 6. At this time, the first lifting rod 6 rises and resets under the action of the first spring 18 and the first lifting plate 8, which drives the first locking groove 10 on the locking block 9 to be inserted and locked into the locking block 11 on the fixed wing 2, thus completing the quick installation of the fuselage 1 and the fixed wing 2. When disassembling, press the first lifting rod 6 again to unlock the locking block 11 and the first locking groove 10 on the locking block 9, thus completing the quick disassembly of the fixed wing 2.

[0029] The mounting base 3 is provided with a mounting groove 21. A second lifting rod 22 is installed on the mounting base 3, penetrating the mounting groove 21 and extending into the interior of the mounting base 3. A second lifting plate 19 is installed in the middle of the second lifting rod 22, which is slidably connected to the inner wall of the mounting groove 21. A second spring 20 is installed between the bottom wall of the second lifting plate 19 and the inner bottom wall of the mounting groove 21. One end of the multi-rotor mounting frame 4 extends into the mounting base 3 and has a second locking groove 23. The bottom of the second lifting rod 22 is adapted to the second locking groove 23. When installing the multi-rotor mounting frame 4, the second lifting rod is first... 22 is lifted to compress the second spring 20. After the multi-rotor mounting bracket 4 is inserted into the mounting base 3, the second lifting rod 22 is released. When the second locking groove 23 slides below the second lifting rod 22, the second lifting rod 22 extends into the second locking groove 23 under the action of the second spring 20 to complete the locking installation of the mounting base 3 and the multi-rotor mounting bracket 4.
