Description

Technical Field

[0001] This utility model relates to a quick-release locking latch for the wing of a composite wing unmanned aerial vehicle (UAV), belonging to the field of UAV technology. Background Technology

[0002] Small compound-wing UAVs are characterized by their small size, light weight, low takeoff and landing requirements, and flexible deployment, and are widely used in aerial surveying, agricultural plant protection, power line inspection, and emergency rescue. For ease of transport, the connection between the outer wing and the middle wing of a compound-wing UAV usually adopts a detachable structural design. Common connection methods include bolted connections and snap-fit ​​connections. Bolted connections have high strength, but assembly and disassembly require tools such as wrenches, which is not conducive to rapid deployment and maintenance. Snap-fit ​​connections do not require tools, but their connection stability is easily affected by vibration and impact, and there is a risk of the snaps loosening after long-term use, which affects flight safety. Utility Model Content

[0003] To address the shortcomings of existing connection methods, this utility model proposes a quick-release locking mechanism for the wings of a composite wing UAV, which combines ease of operation with reliable connection. It effectively solves the problems of cumbersome assembly and disassembly and insufficient reliability in existing connection methods, and avoids the risk of loosening that could affect flight safety when vibration or impact occurs.

[0004] The technical solution of this utility model is as follows: A quick-release wing latch for a compound-wing UAV includes a latch cover, a latch clip, a latch fixing seat B, a latch fixing seat A, and a latch self-locking mechanism. The latch cover is hinged to the latch fixing seat B, the latch clip is hinged to the latch cover, and the latch clip is latched to the latch fixing seat A. The latch self-locking mechanism includes a latch self-locking lever, a hinge pin B, and a torsion spring. The latch self-locking lever is hinged to the latch cover via the hinge pin B, and the torsion spring is mounted on the hinge pin B. Lugs corresponding to the latch self-locking lever are provided on the latch fixing seat B. When locked, the latch self-locking lever and the lugs on the latch fixing seat B form a latching connection under the torsion of the torsion spring.

[0005] As a preferred embodiment of this utility model, the latch and the latch cover are hinged together by hinge pin A.

[0006] As a preferred embodiment of this utility model, the upper cover of the latch and the latch fixing seat B are hinged together by two hinge pins C.

[0007] As a preferred embodiment of this utility model, the locking fixing seat A and the locking fixing seat B are respectively provided with a plurality of mounting holes for connecting with the middle wing / outer wing.

[0008] As a preferred embodiment of this utility model, the latch is provided with a groove or a hole, and the latch fixing seat A is provided with a boss that corresponds to the groove or hole. When locked, the boss of the latch fixing seat A is engaged in the groove or hole of the latch.

[0009] As a preferred embodiment of this invention, the latch forms a hook structure at the bottom end of the self-locking lever, and when locked, the hook structure is used to hook the ear piece.

[0010] The advantages of this utility model are: When the latch is locked, the self-locking latch plate connected to the latch cover hooks onto the lug extending from the latch fixing seat B. Under the torsion of the torsion spring, the self-locking latch plate and the lug on the latch fixing seat B remain in contact and cannot rotate freely, thus restricting the rotation of the latch cover and the latch latch, and achieving the locking of the latch latch and the latch fixing seat A. The latch has a self-locking function and will not loosen when subjected to vibration or impact, ensuring high reliability. When unlocking the latch, move the latch self-locking lever to release the limiting position of the latch self-locking lever on the ear plate of the latch fixing seat B. At the same time, lift the latch cover upward, causing the latch buckle to rotate around the latch cover. The locking hole on the latch buckle disengages from the protrusion on the latch fixing seat A, thereby unlocking the latch buckle from the latch fixing seat A. This makes the operation convenient and efficient. Attached Figure Description

[0013] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1-4As shown, this embodiment is a quick-release latch for the wing of a compound wing UAV, including a latch cover 4, a latch buckle 8, a hinge pin A9, a latch fixing seat B10, a hinge pin C11, a latch fixing seat A12, and a latch self-locking mechanism.

[0015] In this embodiment, the quick-release latch 3 is installed at the connection between the middle wing 1 and the outer wing 2. The latch fixing seat A12 has two mounting holes and is fixedly connected to the middle wing 1 through the two mounting holes. The latch fixing seat B10 has four mounting holes and is connected to the outer wing 2 through the four mounting holes. In practical applications, the number of mounting holes of the latch fixing seat A12 and the latch fixing seat B10 can be adjusted appropriately. At the same time, the installation positions of the latch fixing seat A12 and the latch fixing seat B10 can also be interchanged. The latch cover 4 and the latch fixing seat B10 are connected by two... Hinged by hinge pin C11, the upper cover 4 of the latch can rotate around the latch fixing seat B10 with hinge pin C11 as the axis; the latch 8 and the upper cover 4 are hinged by hinge pin A9, and the latch 8 can rotate around the upper cover 4 with hinge pin A9 as the axis; a locking hole 14 is provided on the latch 8, and a boss 13 corresponding to the locking hole 14 is provided on the latch fixing seat A12. When locked, the boss 13 of the latch fixing seat A12 is engaged in the locking hole 14 of the latch 8; in practical applications, the locking hole 14 on the latch 8 can also be replaced by a groove.

[0016] The self-locking mechanism includes a self-locking lever 5, a hinge pin B6, and a torsion spring 7. The self-locking lever 5 is hinged to the upper cover 4 of the lock via the hinge pin B6. The self-locking lever 5 can rotate around the upper cover 4 of the lock with the hinge pin B6 as the axis. The torsion spring 7 is installed on the hinge pin B6. A lug 15 corresponding to the self-locking lever 5 is provided on the lock fixing seat B10. When locked, the self-locking lever 5 and the lug 15 on the lock fixing seat B10 form a snap-fit ​​connection under the torsion of the torsion spring 7. In this embodiment, a locking hook structure 51 is formed at the bottom end of the self-locking lever 5. When locked, the locking hook structure 51 is used to hook the lug 15.

[0017] Locking: Lift the upper cover 4 of the lock and rotate the latch 8 at the same time so that the protrusion 13 on the latch fixing seat A12 can enter the latch hole 14 of the latch 8. Press the upper cover 4 of the lock down. The self-locking latch 5 connected to the upper cover 4 hooks the ear piece 15 protruding from the latch fixing seat B10. Under the torsion of the torsion spring 7, the self-locking latch 5 and the ear piece 15 on the latch fixing seat B10 always remain in contact and cannot rotate freely, thereby restricting the rotation of the upper cover 4 of the lock and the latch 8, and realizing the locking of the latch 8 and the latch fixing seat A12.

[0018] Unlocking the latch: Move the latch self-locking lever 5 to release the limitation of the latch self-locking lever 5 on the ear piece 15 of the latch fixing seat B10. At the same time, lift the latch cover 4 upward, causing the latch buckle 8 to rotate around the latch cover 4. The buckle hole 14 on the latch buckle 8 and the protrusion 13 on the latch fixing seat A12 are disengaged, thereby unlocking the latch buckle 8 from the latch fixing seat A12.
