Description

Technical Field

[0001] This utility model relates to the field of drone landing gear technology, and in particular to a drone landing gear that can be quickly disassembled. Background Technology

[0002] The rapid development of drone technology has placed higher demands on the convenience and reliability of landing gear. Traditional drone landing gear is usually fixed to the fuselage landing gear bay with bolts or screws. Although this method is secure, the operation is often cumbersome when the landing gear needs to be disassembled frequently for transportation, maintenance, replacement or adaptation to different mission scenarios. It requires the use of special tools to tighten or loosen multiple connecting parts, which is time-consuming and inconvenient to operate in confined spaces or in the field. In addition, repeated disassembly and assembly can easily lead to stripped threads or loss of connecting parts, affecting the reliability of the connection.

[0003] Existing detachable landing gear connection structures generally suffer from low disassembly and assembly efficiency and inconvenient operation, especially in scenarios requiring rapid replacement or storage. At the same time, the complexity of the connection structure may lead to component damage or improper installation, affecting flight safety. In addition, traditional connection methods cannot achieve truly "rapid" disassembly and assembly while ensuring connection strength, often requiring a compromise between convenience and stability.

[0004] Therefore, the inventors urgently needed a drone landing gear that could be quickly disassembled to solve the above problems. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a quick-detachable drone landing gear, aiming to solve the problems of cumbersome and inefficient drone landing gear disassembly and assembly processes in the existing technology, and the difficulty in achieving truly quick disassembly and assembly while ensuring connection reliability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a quick-release unmanned aerial vehicle (UAV) landing gear, including a landing gear bay module. The circumferential outer wall of the landing gear bay module is evenly distributed with several radially protruding quick-release bases. Each quick-release base has a through hole at its lower part and a guide groove with its opening facing the axis of the landing gear bay module at its inner top. Each quick-release base is snapped into a tripod assembly. The tripod assembly includes a snap-fit ​​head structure, which includes a snap-fit ​​body and an elastic pressing component hinged to the upper end of the snap-fit ​​body. The lower end of the snap-fit ​​body has a protrusion adapted to the through hole, and the upper end of the elastic pressing component has a locking protrusion matching the shape of the guide groove.

[0007] Based on the above, the beneficial effects of a quick-detachable drone landing gear are that it solves the problems of cumbersome and inefficient drone landing gear disassembly and assembly processes in existing technologies, and the difficulty in achieving truly quick disassembly and assembly while ensuring connection reliability; mainly reflected in:

[0008] 1. This utility model provides multiple mounting points by having several radially protruding quick-release bases evenly distributed on the circumferential outer wall of the landing gear bay module, allowing the landing gear assembly to be directly snapped together. This achieves an overall modular layout and rapid positioning and installation of the landing gear, and initial assembly can be completed without tools. Furthermore, the through hole at the bottom of the quick-release base matches the protrusion at the bottom of the snap-fit ​​body, achieving precise positioning and bottom fixation of the landing gear assembly during installation, ensuring the initial stability of the connection. The guide groove at the top of the quick-release base matches the shape of the locking protrusion at the top of the snap-fit ​​pressing block, achieving sliding guidance and locking of the locking protrusion in the guide groove, ensuring reliable connection of the landing gear assembly in flight.

[0009] 2. This utility model has a tripod assembly snapped into each quick-release base, and uses a snap-fit ​​head structure to achieve quick engagement, realizing tool-free disassembly and installation of the landing gear, which significantly improves disassembly and assembly efficiency. Furthermore, by integrating the snap-fit ​​body, snap-fit ​​pressing block and pressing spring into a snap-fit ​​head structure, the tripod assembly can be unlocked by a single point pressing operation, simplifying the disassembly process.

[0010] 3. This utility model achieves stable locking and quick separation of the leg assembly by inserting the protrusion into the through hole and pushing the locking protrusion into the guide groove during installation, thus solving the inefficiency problem of traditional bolt connections.

[0011] Furthermore, the number of quick-release bases is four, and they are evenly distributed circumferentially on the landing gear bay module.

[0012] Furthermore, the guide groove is a Π-shaped guide groove, and the lower surface of the two vertical walls of the guide groove is a guide slope that slopes outward from the outer surface of the landing gear bay module. When the landing gear assembly is installed in place, the guide slope fits against the upper end surface of the buckle pressing block.

[0013] Based on the above, the beneficial effect of the guide slope is that the snap-fit ​​pressing block is subjected to gradual compression during installation, resulting in a smooth transition of locking force, avoiding installation resistance caused by sudden locking, and ensuring that the locking protrusion and the guide groove form surface contact after installation, thereby improving connection stability.

[0014] Furthermore, the inner side of the upper surface of the quick-release base includes a first inclined surface and a second inclined surface connected together. The first inclined surface is close to the landing gear bay module body and has an angle of 10° to 20° with the horizontal plane, while the second inclined surface is far from the landing gear bay module body and has an angle of 25° to 35° with the horizontal plane.

[0015] Furthermore, the locking protrusion is a triangular block, and the inclined surface of the triangular block on the side away from the landing gear bay module is in contact with the second inclined surface.

[0016] Based on the above, the beneficial effect of triangular blocks is that, through optimized geometric design, the structural strength is guaranteed while minimizing the increase in weight.

[0017] Furthermore, the elastic pressing component includes a snap-on pressing block and a pressing spring connecting the snap-on body and the snap-on pressing block. The locking protrusion is disposed at the upper end of the snap-on pressing block. The upper end of the snap-on body is provided with a hinge groove. The two side walls of the hinge groove are provided with hinge shaft holes. The snap-on pressing block is hinged to the snap-on body through a pin passing through the hinge shaft hole.

[0018] Based on the above, the beneficial effect of the hinge groove is that it provides a precise installation positioning reference for the snap-fit ​​pressing block.

[0019] Furthermore, the bottom of the articulated groove is provided with a first spring groove on the side away from the landing gear bay module, and the lower end face of the snap-on pressing block is provided with a second spring groove. The lower end of the pressing spring is fixed in the first spring groove, and the upper end abuts against the second spring groove.

[0020] Furthermore, the tripod assembly also includes a tripod rod, the upper end of which is threadedly connected to the buckle body.

[0021] Furthermore, the quick-release base has a structure that is wider at the top and narrower at the bottom, and is hollow inside.

[0022] Based on the above, the beneficial effect of the structure that is wide at the top and narrow at the bottom and hollow inside is that it forms an expanded force-bearing platform at the top of the base, which evenly distributes the impact force of the UAV landing to the landing gear bay module.

[0023] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0029] like Figures 1-4 As shown, a quick-release unmanned aerial vehicle (UAV) landing gear includes a landing gear bay module 1. The circumferential outer wall of the landing gear bay module 1 is evenly distributed with several radially protruding quick-release bases 11. Each quick-release base 11 has a through hole 111 at its lower part and a guide groove 112 with an opening facing the axis of the landing gear bay module 1 at its inner top. Each quick-release base 11 is snapped into connection with a tripod assembly 2. The tripod assembly 2 includes a snap-fit ​​head structure 21, which includes a snap-fit ​​body 211 and an elastic pressing component hinged to the upper end of the snap-fit ​​body 211. The lower end of the snap-fit ​​body 211 has a protrusion 2111 adapted to the through hole 111, and the upper end of the elastic pressing component has a locking protrusion 2121 matching the shape of the guide groove 112.

[0030] The number of quick-release bases 11 is four, and they are evenly distributed circumferentially on the landing gear bay module 1.

[0031] The guide groove 112 is a Π-shaped guide groove. The lower surfaces of the two vertical walls of the guide groove 112 are guide slopes that slope outward from the outer surface of the landing gear bay module 1. When the landing gear assembly 2 is installed in place, the guide slopes fit against the upper surface of the buckle pressing block 212.

[0032] The upper surface of the quick-release base 11 includes a first inclined portion 113 and a second inclined portion 114 connected to each other. The first inclined portion 113 is close to the main body of the landing gear bay module 1 and has an angle of 10° to 20° with the horizontal plane. The second inclined portion 114 is far away from the main body of the landing gear bay module 1 and has an angle of 25° to 35° with the horizontal plane.

[0033] The locking protrusion 2121 is a triangular block, and the inclined surface of the triangular block away from the landing gear bay module 1 is in contact with the second inclined surface 114.

[0034] The elastic pressing component includes a snap-on pressing block 212 and a pressing spring 213 connecting the snap-on body 211 and the snap-on pressing block 212. The locking protrusion 2121 is disposed at the upper end of the snap-on pressing block 212. The upper end of the snap-on body 211 is provided with a hinge groove 2112. The two side walls of the hinge groove 2112 are provided with hinge shaft holes 2113. The snap-on pressing block 212 is hinged to the snap-on body 211 by a pin passing through the hinge shaft hole 2113.

[0035] The bottom of the hinge groove 2112 is provided with a first spring groove 2114 on the side away from the landing gear bay module 1, and the lower end face of the snap-on pressing block 212 is provided with a second spring groove 2122. The lower end of the pressing spring 213 is fixed in the first spring groove 2114, and the upper end abuts in the second spring groove 2122.

[0036] The tripod assembly 2 also includes a tripod rod 22, the upper end of which is threadedly connected to the buckle body 211.

[0037] The quick-release base 11 has a structure that is wider at the top and narrower at the bottom and is hollow inside.

[0038] In summary, the specific embodiments of this utility model are as follows;

[0039] During installation, first, align the protrusion 2111 of the tripod assembly 2 with the through hole 111 of the quick-release base 11 and insert it vertically to achieve axial pre-fixation of the tripod assembly; then push the tripod assembly 2 inward so that the locking protrusion 2121 of the snap-on pressing block 212 slides into the inner side of the upper end of the quick-release base 11, while the pressing spring 213 is compressed and stores energy, and the locking protrusion 2121 transitions to the 25°~35° steep slope of the second slope 114. The triangular slope of the locking protrusion 2121 fits tightly with the second slope 114, generating a locking force, and the pressing spring 213 is released. At this time, the protrusion 2111 and the through hole 111 form a vertical limit, and the locking protrusion 2121 and the guide groove 112 form a snap lock.

[0040] During disassembly, press the buckle pressing block 212 downward with one finger to overcome the elastic force of the pressing spring 213 and disengage the locking protrusion 2121 from the guide groove 112. Then pull the leg assembly 2 outward, and the locking protrusion 2121 slides out in the opposite direction along the second inclined surface 114. After the locking protrusion 2121 is completely disengaged from the quick-release base 11, lift the leg assembly 2 vertically to disengage the protrusion 2111 from the through hole 111, thus completing the disassembly.

[0041] It should be noted that the hollow structure of the quick-release base 11, which is wider at the top and narrower at the bottom, disperses the landing impact force to the landing gear bay module 1. The articulation groove 2112 and the articulation shaft hole 2113 ensure the precise pressing trajectory of the snap-on pressing block 212. The first spring groove 2114 and the second spring groove 2122 fix the pressing spring 213, ensuring the efficiency of spring force transmission. The entire process requires no tools, and the single-leg assembly and disassembly time is less than 1 second.

[0042] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
