Description

Technical Field

[0001] This invention relates to a lightweight quick-release clip for the rapid disassembly and installation of drone components. Background Technology

[0002] Drones consist of components such as the fuselage and wings. To save space, the wings and other parts typically need to be disassembled and stored separately during transportation and storage, and then reassembled when needed. Currently, the disassembly and assembly of wings and fuselage mostly rely on bolts. This method is time-consuming and labor-intensive, requires additional tools, and bolts and other parts are prone to loss, hindering operation. Therefore, a quick-release structure is needed to rapidly solve the disassembly and assembly problem. Summary of the Invention

[0003] To address the aforementioned problems in existing technologies, the inventors have proposed an innovative lightweight quick-release clip for the rapid disassembly and installation of drone components, solving the problem that existing drone components cannot be quickly disassembled and installed. It eliminates the need for additional disassembly and installation tools and innovatively employs an elastic element to prevent loosening, avoiding automatic unlocking due to vibration or impact. This quick-release clip has a compact structure, is lightweight, and has minimal impact on drone flight.

[0004] According to the present invention, a lightweight quick-release clip for rapid disassembly and installation of drone components is provided, characterized in that it comprises:

[0005] The components include a claw lock, connecting frame, fixed end pin, pressing plate, moving end pin, elastic element, fixed base, spring slot, and return spring.

[0006] in:

[0007] The mounting base is connected to the drone body via the outer and inner through holes using the first bolt.

[0008] Above the outer circular through-hole is an elastic element.

[0009] A through hole is provided on the base plate of the elastic element. The first bolt is used to connect the elastic element and the fixed base to the drone body through the through hole.

[0010] One end of the pressing plate is connected to the lug of the fixed base via a fixed end pin.

[0011] A return spring is connected to the back of the pressing plate, and the return spring passes through a spring retainer.

[0012] The other end of the pressing plate is connected to the pin on the moving end.

[0013] The connector has a through hole at the bottom for bolting it onto the drone components to be assembled or disassembled.

[0014] The upper part of the connecting frame is a snap-fit ​​limiting surface, used to fix the snap-fit ​​claws of the snap-fit ​​lock.

[0015] The claw lock can rotate relative to the pressing plate around the moving end pin.

[0016] The pressing plate can rotate relative to the fixed base around the fixed end pin. Attached Figure Description

[0021] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown in Figure 4, the lightweight quick-release buckle for rapid disassembly and installation of UAV components according to the present invention includes a claw lock 1, a connecting frame 2, a fixed end pin 3, a pressing plate 4, a moving end pin 5, an elastic element 6, a fixed base 7, a spring slot 8, and a return spring 9.

[0023] The mounting base 7 is bolted to the drone fuselage via two through holes 7-a and 7-b. Above the outer through hole is an elastic element 6, made of spring steel, which provides a certain degree of elasticity. The base plate of the elastic element 6 has a through hole 6-a, through which the same bolt passes to connect the elastic element 6 and the mounting base 7 to the drone fuselage.

[0024] One end of the pressing plate 4 is connected to the ear piece 7-c of the fixed base 7 via the fixed end pin 3.

[0025] A return spring 9 is connected to the back of the pressing plate 4. The return spring 9 passes through the spring slot 8, and the other end is connected to the moving end pin 5. The bottom of the connecting frame 2 has two through holes 2-a and 2-b, which can be bolted to the drone parts to be disassembled or assembled, such as wings or canopies. The upper part of the connecting frame 2 is a buckle limiting surface 2-c, which is used to fix the claw of the claw lock 1. The claw lock 1 can rotate relative to the pressing plate 4 around the moving end pin 5, and the pressing plate 4 can rotate relative to the fixed base 7 around the fixed end pin 3.

[0026] During disassembly, manually push the upper part of the elastic element 6 outward while simultaneously pushing the pressing plate 4 upward, causing the square slot 4-a of the pressing plate 4 to disengage from the elastic element 6. At this time, under the action of the return spring 9, the pressing plate 4 rotates counterclockwise around the fixed end pin 3, and the claw lock 1 rotates clockwise relative to the pressing plate 4 around the moving end pin 5. The claw disengages from the locking limit surface, completing the separation of the fixed base 7 and the connecting frame 2, and realizing the rapid disassembly of the wings, etc.

[0027] During installation, first align the claw lock 1 with the buckle limiting surface 2-c of the connecting bracket 2 and snap it on. Then, press the pressing plate 4 clockwise downwards to counteract the elastic force of the return spring 9. At the same time, manually push the upper part of the elastic element 6 outwards so that the square slot 4-a of the pressing plate 4 passes through the elastic element 6 and is pressed to the bottom to lock it, thus completing the installation of the fixed base 7 and the connecting bracket 2.

[0028] According to the present invention, the unmanned aerial vehicle (UAV) components to be disassembled and installed include at least one selected from the wings, canopy, horizontal tail, vertical tail, and tail boom.

[0029] The advantages and / or beneficial effects of the present invention include:

[0030] 1. The elastic element has an anti-loosening function.

[0031] Conventional quick-release devices lack anti-loosening features, posing significant safety hazards. For example, during landing and touchdown, the ground exerts a large instantaneous external force on the drone. At this time, the claws and buckle limiting surfaces of conventional quick-release devices, lacking anti-loosening devices, may abnormally separate due to the force, causing the connection between the wing and the fuselage to fail, which can easily lead to a safety accident.

[0032] The present invention provides an elastic element that prevents the square slot of the pressing plate from detaching from the elastic element when subjected to external impact, thus ensuring the safety and reliability of the structure.

[0033] 2. Features a quick-disassembly structure

[0034] Conventional component connection devices rely on bolts and nuts for fixing, which is cumbersome, time-consuming and labor-intensive, and requires the assistance of various tools to complete the disassembly and assembly.

[0035] The quick-release buckle of the present invention does not use bolts and nuts, and can be disassembled and installed by hand without tools, making it convenient to use.

[0036] 3. Includes lightweight design

[0037] Conventional component connection devices are large in size and weight, which has a certain adverse effect on the flight of drones.

[0038] The quick-release buckle structure of the present invention is simple, occupies little space, and uses high-strength lightweight materials, which can meet the connection safety requirements while being lightweight.
