Abstract
Description
Technical Field
[0001] This utility model relates to the field of drone mounting technology, and more specifically, to a drone mounting structure. Background Technology
[0002] Unmanned aerial vehicles (UAVs), with their efficient and flexible flight characteristics, play a vital role in fields such as inspection, surveying, logistics, and emergency rescue. However, the insufficient adaptability of their payload structures has become one of the key factors restricting operational efficiency. Currently, most UAVs still use a fixed structure design for their payloads, that is, fixing the mission payload (such as cameras, sensors, cargo boxes, etc.) to the underside of the fuselage using bolts, clips, or rigid brackets. While this design is simple in structure and stable in installation, it has obvious limitations:
[0003] First, fixed mounting structures are typically only compatible with payloads of specific shapes or sizes, failing to flexibly adapt to different mission requirements. For example, inspection operations may require the mounting of thermal imagers or LiDARs of different specifications; in logistics transportation, the size and weight of the cargo box may also vary depending on order requirements. Traditional fixed structures are difficult to adjust quickly, necessitating the use of multiple specialized mounts for drones, increasing usage costs and maintenance complexity.
[0004] Secondly, due to the lack of adaptive adjustment capabilities, fixed mounts have poor locking stability when dealing with irregularly shaped loads, such as irregular equipment. The loads are prone to shaking or even falling off during flight due to airflow disturbances or UAV maneuvers, affecting data acquisition accuracy or transportation safety. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the problems existing in the prior art, this utility model provides a mounting structure for unmanned aerial vehicles (UAVs) to solve the technical problem mentioned in the background art that the mounting structure of a UAV is not convenient for flexibly adjusting the mounting and fixing position of the carrier according to the length of the carrier, resulting in poor flexibility and stability.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A mounting structure for a drone includes a mounting plate with fixing plates at both ends. A bidirectional screw is connected between the two sets of fixing plates via a bearing, and a drive motor is mounted on the bidirectional screw. Two sets of drive frames are symmetrically threaded on the bidirectional screw. A limit slide bar is provided on the fixing plate, and the two ends of the drive frame are slidably sleeved on the limit slide bar. A binding strip is provided below the drive frame, and a limit tooth is provided on the outer side of the binding strip. A feeding box is provided on one side of the bottom end of the drive frame, and a locking seat is provided on the other side. An automatic winding structure is provided in the feeding box in conjunction with the binding strip. A limit locking structure and a limit release structure are provided on the locking seat in conjunction with the binding strip. A loading seat is provided between the bottom ends of the two sets of fixing plates.
[0010] The present invention is further configured such that the limiting clamping structure includes a hinge frame, a limiting frame is elastically hinged on the hinge frame, the outer end of the limiting frame is provided with a limiting tongue in cooperation with the limiting teeth, and the inner end is provided with a pressing end in cooperation with the limiting tongue.
[0011] The present invention is further configured such that the hinge frame is provided with an installation shaft, the limiting frame is provided with an installation groove, the limiting frame is rotatably mounted on the installation shaft through the cooperation of the bearing and the installation groove, and a torsion spring is provided between the installation groove and the installation shaft. Through the cooperation of the bearing of the installation shaft and the installation groove, combined with the torsion spring, the limiting frame is elastically hinged on the hinge frame. Thus, in the original state, under the action of the torsion spring itself, the limiting tongue can be kept pressed against the binding strip, so that the limiting tongue and the limiting tooth cooperate to realize the locking and limiting of the binding strip on the locking seat.
[0012] The present invention is further configured such that the limiting release structure includes a mounting frame, on which a first electric push rod is provided. The output end of the first electric push rod cooperates with the pressing end. When the first electric push rod is activated, the output end of the first electric push rod is extended to squeeze the pressing end, causing the pressing end to drive the limiting frame to rotate, thereby causing the limiting tongue to disengage from the limiting teeth on the binding strip, releasing the limitation on the binding strip. This allows the binding strip to spring back and disengage from the locking seat under the elastic force of the elastic winding member. In this way, the binding limitation on the load can be automatically released, realizing the active unloading of the load.
[0013] The present invention is further configured such that a fixed shaft is provided inside the feeding box, and a winding shaft is provided on the fixed shaft via a bearing. An elastic winding element is provided between the winding shaft and the fixed shaft. The elastic winding element is a coil spring or a torsion spring, which is used to drive the winding shaft to automatically rewind. Thus, when the binding strip is stretched, it will drive the winding shaft to rotate, causing the elastic winding element to generate elasticity. Therefore, when the external force on the binding strip is released, the binding strip can be automatically rewound under the action of the elastic winding element.
[0014] The present invention is further configured such that a second electric push rod is provided inside the feeding box, a rack is provided at the output end of the second electric push rod, and a gear is provided at the end of the take-up shaft. The rack and gear mesh, and when the second electric push rod is activated, the rack is controlled to move, causing the rack to move down and mesh with the gear, thereby limiting the rotation of the gear and thus limiting the rotation of the take-up shaft. In this way, when the carrier is fixed by the binding strip, the binding stability of the binding strip on the carrier can be improved.
[0015] The present invention is further provided with a telescopic protective cover between the two sets of drive frames and between the outer side of the drive frame and the corresponding fixed plate. The telescopic protective cover covers the outer side of the bidirectional screw and the limiting slide rod. By setting the telescopic protective cover, the contact between the bidirectional screw and the limiting slide rod and the outside world during use can be reduced, thereby improving the dustproof effect and ensuring the smooth movement of the drive frame.
[0016] The present invention is further configured such that a material feeding port is provided at the bottom of the feeding box, a guide frame is provided on the locking seat, and guide wheels are provided at both the material feeding port and the guide frame. The guide wheels can be used to flexibly guide the binding strip and reduce the wear of the binding strip.
[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides a mounting structure for a drone, which has the following beneficial effects:
[0019] 1. This utility model achieves dynamic adjustment of the binding position by driving two sets of drive frames to move synchronously in opposite directions using a bidirectional screw. Traditional fixed mounting structures are limited by the size of the load and require frequent replacement of parts. However, this design only requires starting the drive motor to allow the binding strip to quickly adapt to loads of different lengths, such as inspection equipment or logistics boxes. For example, when the load is long, the drive frame automatically moves outward to expand the binding distance; when the load is short, it retracts inward to ensure that the binding strip is always close to the center area of the load. The cooperation between the limiting slide bar and the telescopic protective cover further ensures the smoothness of movement and improves the stability and flexibility when mounting the drone.
[0020] 2. This utility model adopts a flexible binding strip with limiting teeth combined with an automatic winding structure, which solves the problem of fixing irregularly shaped carriers. The binding strip can bend and wrap around the contour of the carrier, such as cylindrical sensors or irregular rescue supplies. The engagement mechanism of the limiting tongue and the limiting teeth realizes quick fixing with a pull. Compared with traditional bolt fastening methods, it shortens the operation time. In addition, the rack locks the winding shaft through the second electric push rod, preventing the binding strip from rebounding or loosening due to airflow disturbance during flight, thus ensuring the stability of the carrier.
[0021] 3. This utility model integrates the limit release structure of the first electric push rod, realizing precise aerial delivery of the carrier. By pressing the pressing end of the limit frame with the first electric push rod, the binding strip can quickly and automatically disengage from the locking seat in a short time to complete the delivery action. It is particularly suitable for point-to-point airdrop by logistics drones. The modular design of the loading seat and binding strip also supports multiple mounting modes: horizontal binding is suitable for flat equipment, such as surveying instruments, while vertical wrapping is suitable for barrel-shaped materials, such as medical bottles. The retractable protective cover design effectively prevents dust, ensures the dust protection effect of the bidirectional screw, and guarantees the stable and smooth movement of the drive frame.

[0032] Please see Figures 1-6 A mounting structure for a drone includes a mounting plate 1, which can be fixed to the bottom of the drone by bolts, clips, etc. Fixing plates 2 are provided at both ends of the mounting plate 1. A bidirectional screw 3 is provided between the two sets of fixing plates 2 via bearings, and a drive motor 4 is provided in conjunction with the bidirectional screw 3. Two sets of drive frames 5 are symmetrically threaded on the bidirectional screw 3. Limiting slide rods 6 are provided on the fixing plates 2. The two ends of the drive frames 5 are slidably sleeved on the limiting slide rods 6. A binding strip 7 is provided below the drive frames 5, and limiting teeth 8 are provided on the outer side of the binding strip 7. A feeding box 9 is provided on one side of the bottom end of the drive frames 5, and a locking seat 10 is provided on the other side. An automatic winding structure is provided inside the feeding box 9 in conjunction with the binding strip 7. A limiting locking structure and a limiting release structure are provided on the locking seat 10 in conjunction with the binding strip 7. A loading seat 11 is provided between the bottom ends of the two sets of fixing plates 2.
[0033] Please see Figures 1-6 As one embodiment of the limiting clamping structure: the limiting clamping structure includes a hinge frame 12, on which a limiting frame 13 is elastically hinged. The outer end of the limiting frame 13 is provided with a limiting tongue 14 in cooperation with the limiting teeth 8, and the inner end is provided with a pressing end 15 in cooperation with the limiting tongue 14.
[0034] Please see Figures 1-6 As one embodiment of the hinge frame 12: the hinge frame 12 is provided with a mounting shaft 16, and the limiting frame 13 is provided with a mounting groove 17. The limiting frame 13 is rotatably mounted on the mounting shaft 16 through the cooperation of the bearing and the mounting groove 17. A torsion spring 18 is provided between the mounting groove 17 and the mounting shaft 16. Through the cooperation of the mounting shaft 16, the mounting groove 17 and the torsion spring 18, the limiting frame 13 can be elastically hinged on the hinge frame 12. Thus, in the original state, under the action of the torsion spring 18 itself, the limiting tongue 14 can be kept pressing against the binding strip 7, so that the limiting tongue 14 and the limiting tooth 8 cooperate to realize the locking and limiting of the binding strip 7 on the locking seat 10.
[0035] Please see Figures 1-6As one implementation of the limit release structure: The limit release structure includes a mounting frame 19, on which a first electric push rod 20 is provided. The output end of the first electric push rod 20 cooperates with the pressing end 15. When the first electric push rod 20 is activated, by controlling the output end of the first electric push rod 20 to extend, it squeezes the pressing end 15, causing the pressing end 15 to drive the limit frame 13 to rotate with the limit tongue 14, thereby causing the limit tongue 14 to disengage from the limit teeth 8 on the binding strip 7, releasing the limit on the binding strip 7. As a result, the binding strip 7 can rebound and disengage from the locking seat 10 under the elastic force of the elastic winding member 23. In this way, the binding limit on the load can be automatically released, realizing the active unloading of the load.
[0036] Please see Figures 1-6 As one implementation of the feeding box 9: a fixed shaft 21 is provided inside the feeding box 9, and a winding shaft 22 is provided on the fixed shaft 21 through a bearing. An elastic winding member 23 is provided between the winding shaft 22 and the fixed shaft 21. The elastic winding member 23 can be a coil spring or a torsion spring 18, which is used to realize the automatic rewinding of the winding shaft 22. When the binding strip 7 is stretched, it will drive the winding shaft 22 to rotate, so that the elastic winding member 23 will generate elasticity. Then, when the external force of the binding strip 7 is released, the binding strip 7 can be automatically rewound under the action of the elastic winding member 23.
[0037] Furthermore, this utility model provides a second electric push rod 24 inside the feeding box 9. The output end of the second electric push rod 24 is provided with a rack 25, and the end of the take-up shaft 22 is provided with a gear 26. The rack 25 and gear 26 mesh. When the second electric push rod 24 is activated, the rack 25 is moved by controlling the rack 25 to move downward and mesh with the gear 26, thereby restricting the rotation of the gear 26 and thus restricting the rotation of the take-up shaft 22. In this way, when the carrier is fixed by the binding strip 7, the binding stability of the binding strip 7 on the carrier can be improved. Preferably, the take-up shaft 22 and the fixing shaft 21 are provided in two sets inside the feeding box 9, and the binding strip 7 is reciprocated between the two sets of take-up shafts 22.
[0038] Please see Figures 1-6 As one implementation of the drive frame 5: a telescopic protective cover 27 is provided between the two sets of drive frames 5 and between the outer side of the drive frame 5 and the corresponding fixed plate 2. The telescopic protective cover 27 covers the outer side of the bidirectional screw 3 and the limiting slide rod 6. By setting the telescopic protective cover 27, the contact between the bidirectional screw 3 and the limiting slide rod 6 and the outside world during use can be reduced, thereby improving the dustproof effect and ensuring the smooth movement of the drive frame 5.
[0039] Please see Figures 1-6As one implementation of the feeding box 9: the feeding box 9 has a feeding port 28 at the bottom, and a guide frame 29 is provided on the locking seat 10. Guide wheels 30 are provided at both the feeding port 28 and the guide frame 29. The guide wheels 30 can be used to flexibly guide the binding strip 7 and reduce the wear of the binding strip 7.
[0040] In summary:
[0041] This utility model uses two sets of drive frames 5 to install corresponding binding strips 7. When in use, the drive motor 4 is started, which controls the rotation of the bidirectional screw 3. With the cooperation of the limit slide rod 6, the two sets of drive frames 5 can be controlled to move synchronously towards each other, so that the two sets of drive frames 5 move closer or further away from each other. In this way, the binding position can be flexibly adjusted when mounting different UAV components. The binding position can be adjusted according to the length or width of the component, thus improving the loading flexibility and loading stability of the component.
[0042] This utility model uses a binding strip 7 structure to bind the carrier to the bottom of the loading seat 11. The binding strip 7 is made of plastic material with flexible winding effect but poor length tensile performance. In this way, the binding strip 7 can flexibly adjust its binding angle according to the shape of the carrier, while achieving stable binding of the carrier and improving the mounting effect of the UAV.
[0043] In this utility model, one end of the binding strip 7 is elastically released through the material release box 9, and the other end can be quickly locked through the cooperation of the limiting tooth 8 and the limiting tongue 14, which improves the ease of installation.
[0044] When using this utility model, the load to be mounted can be placed close to the bottom of the loading seat 11. Then, pull the binding strip 7 so that the binding strip 7 is pulled out of the material box 9 and passes around the bottom of the load. Then, it is inserted between the locking seat 10 and the limiting tongue 14. The binding strip 7 is restricted from detaching from the locking seat 10 by the cooperation of the limiting tongue 14 and the limiting tooth 8.
[0045] Then, the second motor is started, and the rack 25 is moved by the second electric push rod 24, so that the rack 25 moves down and meshes with the gear 26, thereby limiting the rotation of the gear 26, and thus limiting the rotation of the winding shaft 22. This can achieve stable binding of the binding strip 7 to the carrier.
[0046] To ensure stability, after this step, the binding strip 7 can be pushed further towards the locking seat 10 to enhance the binding stability.
[0047] When automatic unloading of the load is required, the first electric push rod 20 can be activated. By controlling the output end of the first electric push rod 20 to extend, it can squeeze the pressing end 15, causing the pressing end 15 to drive the limiting frame 13 to rotate with the limiting tongue 14. This causes the limiting tongue 14 to disengage from the limiting teeth 8 on the binding strip 7, releasing the binding strip 7. As a result, the binding strip 7 can automatically spring back into the discharge box 9 under the elastic force of the elastic winding part 23, disengaging from the locking seat 10, thereby automatically releasing the binding limit on the load and realizing the active unloading of the load. This facilitates the mounting of delivery-type loads.
