The ends of the rotor brackets are fixed inside the main body bracket of the drone by bracket fixing frames.
[0004] Existing racks are bulky when folded up and involve many steps, making them difficult to organize quickly in limited outdoor spaces. Operators also need to spend a lot of time adjusting the rack angles, resulting in low convenience for storage and transportation. Utility Model Content
[0005] The purpose of this invention is to provide a foldable take-off and landing auxiliary support for low-altitude unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A foldable take-off and landing auxiliary support for low-altitude unmanned aerial vehicles (UAVs) includes a main body of the take-off and landing auxiliary support. Fixing blocks are fixedly installed on both sides of the main body of the take-off and landing auxiliary support. An assembly is movably installed on the outer side of the fixing blocks. A connecting plate is movably installed on the bottom of the assembly. A take-off and landing support is fixedly installed on the bottom of the connecting plate. A chassis is fixedly installed on the bottom of the take-off and landing support.
[0008] Also includes:
[0009] A folding mechanism is provided on the top of the connecting plate for folding and storing the take-off and landing bracket;
[0010] A buffer mechanism, located inside the chassis, is used to cushion and protect the take-off and landing brackets, reducing damage to the drone.
[0011] A further improvement of the present invention is that the folding mechanism includes a sleeve plate, the bottom of which is fixedly installed on the top of the connecting plate. A connecting hole is provided on the surface of the sleeve plate, and a bolt is threaded into the connecting hole. The extension end of the bolt is threaded to both sides of the bottom of the assembly.
[0012] A further improvement of this utility model is that: the inner cavity of the fixing block is provided with sliding grooves on both sides, and a slider is movably installed inside the sliding groove, with one side of the slider fixedly installed on the top of both sides of the assembly.
[0013] A further improvement of the present invention is that: a snap-fit block is fixedly installed inside the fixing block, a connecting push block is movably sleeved inside the snap-fit block, and the other end of the connecting push block is fixedly connected to the surface of the assembly.
[0014] A further improvement of the present invention is that a pressing block is movably installed inside the snap-fit block, and a spring-loaded post is fixedly connected to the bottom of the pressing block, with the telescopic end of the bottom of the spring-loaded post fixedly connected to the bottom of the inner cavity of the snap-fit block.
[0015] A further improvement of this utility model is that: the inner wall of the snap-fit block is provided with a snap-fit groove, a movable rod is movably sleeved inside the snap-fit groove, the other end of the movable rod is movably connected to the top of the surface of the pressing block, and compression columns are movably installed at both ends of the top of the pressing block, with the inner side of the compression columns arranged on the side of the connecting push block.
[0016] A further improvement of the present invention is that the buffer mechanism includes a buffer plate, the bottom of one side of the buffer plate is movably installed on the bottom of the chassis, spring columns are fixedly connected to both ends of the buffer plate, the telescopic ends of the spring columns are fixedly connected to the top of the inner cavity of the chassis, a damping column is provided on the side of the spring column, and the upper and lower ends of the damping column are respectively fixedly installed between the chassis and the buffer plate.
[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0018] 1. This utility model provides a foldable take-off and landing auxiliary support for low-altitude drones. When the drone enters the storage or transportation stage, the main body of the drone is separated from the support. Then, the accessory is slid out from inside the fixed block, and the connecting plate is pushed to drive the socket plate to rotate downward around the connecting axis at the bottom of the accessory. This causes the take-off and landing support fixed at the bottom of the connecting plate to rotate synchronously until the take-off and landing support rotates to a storage position parallel to the main body of the take-off and landing auxiliary support, thus realizing the separation and folding storage function. This avoids storage difficulties caused by the large size of the support when unfolded. It is especially suitable for quick organization in limited spaces after outdoor operations, improving the convenience of storage operations.
[0019] 2. This utility model provides a foldable take-off and landing auxiliary support for low-altitude UAVs. When the UAV lands, the weight of the fuselage and the impact load are sequentially transferred to the main body of the take-off and landing auxiliary support. When the buffer plate contacts the ground and bears the impact force, it will squeeze the spring columns fixedly connected at both ends upward, causing the spring columns to be compressed and deformed axially. At the same time, the damping column between the buffer plate and the top of the chassis cavity is compressed synchronously with the upward movement of the buffer plate. The damping column generates a damping force opposite to the direction of movement of the buffer plate through the viscosity of the internal damping medium, which slows down the upward movement speed of the buffer plate, further consumes the kinetic energy of the impact force, and avoids the violent rebound of the spring column caused by rapid compression, thus achieving the function of buffering and shock absorption.

[0026] The present invention will be further described in detail below with reference to embodiments:
[0027] like Figure 1-5 As shown, this utility model has the following three specific embodiments.
[0028] Example 1
[0029] This utility model provides a foldable take-off and landing auxiliary support for low-altitude unmanned aerial vehicles, including a take-off and landing auxiliary support body 1, fixing blocks 2 are fixedly installed on both sides of the take-off and landing auxiliary support body 1, an assembly 3 is movably installed on the outer side of the fixing blocks 2, a connecting plate 4 is movably installed on the bottom of the assembly 3, a take-off and landing support 5 is fixedly installed on the bottom of the connecting plate 4, and a chassis 6 is fixedly installed on the bottom of the take-off and landing support 5.
[0030] Also includes:
[0031] Folding mechanism, which is set on the top of the connecting plate 4, is used to fold and store the lifting and landing bracket 5;
[0032] The buffer mechanism is located inside the chassis 6 and is used to buffer and protect the take-off and landing brackets 5, reducing damage to the drone.
[0033] like Figure 1 As shown, the assembly 3 and the connecting plate 4 are connected by a movable shaft. After unlocking, the connecting plate 4 can rotate downwards around the bottom rotation shaft of the assembly 3, causing the landing bracket 5 fixed at the bottom to rotate synchronously. When the landing bracket 5 is fully unfolded, the locking component of the folding mechanism automatically resets, fixing the connecting plate 4 and the assembly 3, ensuring that the bracket will not shake or fold during take-off and landing, providing stable support for the drone. Together with the top of the landing auxiliary bracket body 1 installed on the bottom of the drone, it achieves the function of folding assembly. In addition, when the drone lands, the weight of the fuselage and the impact force are transmitted to the fixed blocks 2 on both sides through the landing auxiliary bracket body 1, and then transmitted to the landing bracket 5 through the assembly 3 and the connecting plate 4. Finally, the chassis 6 contacts the ground. It uses the preset buffer component inside the chassis 6 to convert the rigid impact force into the energy of elastic deformation, gradually dissipating the impact force and achieving the function of buffer protection.
[0034] Example 2
[0035] The difference from Embodiment 1 is that this embodiment discloses a connecting plate 41 and a buffer plate 62. The folding mechanism includes a connecting plate 41, the bottom of which is fixedly installed on the top of the connecting plate 4. A connecting hole 42 is provided on the surface of the connecting plate 41, and a bolt 32 is threadedly connected inside the connecting hole 42. The extended end of the bolt 32 is threadedly connected to both sides of the bottom of the assembly 3. The buffer mechanism includes a buffer plate 62, the bottom of one side of which is movably installed on the bottom of the chassis 6. Spring columns 61 are fixedly connected to both ends of the buffer plate 62. The telescopic end of the spring column 61 is fixedly connected to the top of the inner cavity of the chassis 6. A damping column 63 is provided on the side of the spring column 61, and the upper and lower ends of the damping column 63 are respectively fixedly installed between the chassis 6 and the buffer plate 62.
[0036] like Figure 2 , 3As shown in Figure 5, when the drone needs to be stored or transported after completing its mission, the accessory 3 slides out from inside the fixed block 2. The operator can push the connecting plate 4, causing the socket plate 41 to rotate downwards around the connecting axis at the bottom of the accessory 3, thereby causing the landing bracket 5 fixed at the bottom of the connecting plate 4 to rotate synchronously. The landing bracket 5 rotates to a storage position parallel to the main body 1 of the landing auxiliary bracket, achieving the function of folding and storing. In addition, when the drone takes off or lands, the weight of the fuselage and the impact load are sequentially transferred to the main body 1 of the landing auxiliary bracket, which works with the buffer at the bottom of the chassis 6 to buffer the impact. The buffer plate 62 contacts the ground and bears the impact. When impacted, the buffer plate 62 presses upward against the spring columns 61 fixedly connected at both ends, causing the spring columns 61 to compress and deform axially, converting part of the impact force into the elastic potential energy of the spring. At the same time, the damping column 63 between the buffer plate 62 and the top of the inner cavity of the chassis 6 is compressed synchronously with the upward movement of the buffer plate 62. The damping column 63 generates a damping force opposite to the direction of movement of the buffer plate 62 through the viscosity of the internal damping medium, slowing down the upward movement speed of the buffer plate 62, further consuming the kinetic energy of the impact force, and preventing the spring columns 61 from rebounding violently due to rapid compression, thus achieving the function of buffering and shock absorption, and further buffering and protecting.
[0037] Example 3
[0038] The difference from Embodiment 2 is that this embodiment discloses a snap-fit block 21 and a pressing block 22. The inner cavity of the fixing block 2 has sliding grooves 20 on both sides. A slider 31 is movably installed inside the sliding grooves 20. One side of the slider 31 is fixedly installed on the top of both sides of the assembly 3. The snap-fit block 21 is fixedly installed inside the fixing block 2. A connecting push block 33 is movably sleeved inside the snap-fit block 21. The other end of the connecting push block 33 is fixedly connected to the surface of the assembly 3. The pressing block 22 is movably installed inside the snap-fit block 21. A spring-loaded post 23 is fixedly connected to the bottom of the pressing block 22. The telescopic end of the bottom of the spring-loaded post 23 is fixedly connected to the bottom of the inner cavity of the snap-fit block 21. A snap-fit groove 26 is opened on the inner wall of the snap-fit block 21. A movable rod 24 is movably sleeved inside the snap-fit groove 26. The other end of the movable rod 24 is movably connected to the top of the surface of the pressing block 22. Compression posts 25 are movably installed at both ends of the top of the pressing block 22. The inner side of the compression posts 25 is located on the side of the connecting push block 33.
[0039] like Figure 4As shown, the operator presses the assembly 3, causing the connecting push block 33 to engage with the top of the pressing block 22. The pressing block 22 moves downward under pressure, simultaneously causing the bottom-fixed rebound column 23 to compress and deform. As the pressing block 22 moves downward, the movable rod 24, which is movably connected to the top of its surface, swings down accordingly. The end of the movable rod 24 away from the pressing block 22 moves and engages with the slot 26. Meanwhile, the connecting push block 33 pushes the pressing block 22 into the engaging block 21, causing the compression column 25 to be affected by the internal groove and move inward. The device moves to the side, thus engaging with both sides of the connecting push block 33 to achieve a limit lock function. When it needs to be unlocked, the operator presses the assembly 3 again. When the pressing block 22 moves down, the movable rod 24 connected to the top of its surface swings down accordingly. The end of the movable rod 24 away from the pressing block 22 disengages from the slot 26 on the inner wall of the engaging block 21, releasing the locking of the pressing block 22 by the engaging block 21, making it easy for the pressing block 22 to move outward, thus achieving the unlocking function and facilitating the stable folding and adjustment of the drone bracket.
[0040] The working principle of this low-altitude UAV foldable take-off and landing auxiliary support will be explained in detail below.
[0041] like Figure 1-5 As shown, when the drone completes its mission and needs to be stored or transported, the accessory 3 slides out from inside the fixed block 2. The operator can push the connecting plate 4, causing the socket plate 41 to rotate downwards around the connecting axis at the bottom of the accessory 3, thereby causing the landing bracket 5 fixed at the bottom of the connecting plate 4 to rotate synchronously. The landing bracket 5 rotates to a storage position parallel to the main body 1 of the landing auxiliary bracket, achieving the function of folding and storing. In addition, when the drone takes off or lands, the weight of the fuselage and the impact load are sequentially transferred to the main body 1 of the landing auxiliary bracket, which works with the buffer at the bottom of the chassis 6 to buffer the impact. The buffer plate 62 contacts the ground and bears the impact. Upon impact, the buffer plate 62 presses upward against the spring columns 61 fixedly connected at both ends, causing the spring columns 61 to compress and deform axially, converting part of the impact force into the elastic potential energy of the spring. Simultaneously, the damping column 63 between the buffer plate 62 and the top of the inner cavity of the chassis 6 is compressed synchronously with the upward movement of the buffer plate 62. Through the viscous effect of the internal damping medium, the damping column 63 generates a damping force opposite to the direction of movement of the buffer plate 62, slowing down the upward movement speed of the buffer plate 62, further consuming the kinetic energy of the impact force, and preventing the spring columns 61 from rebounding violently due to rapid compression, thus achieving the function of buffering and shock absorption, and further buffering and protecting.
[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
