Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV capable of automatically laying targets. Background Technology

[0002] Targets are physical markers used for ground location marking or coordinate reference in field operations such as surveying, remote sensing, and geological exploration. They are typically plate-shaped objects with high-contrast colors or special reflective materials, laid out in the area to be measured as reference points for drone aerial photography or ground surveying. Their function is to improve image interpretation accuracy and spatial positioning accuracy, making them an indispensable auxiliary tool in these operations.

[0003] Currently, target deployment relies heavily on manual transport to designated points, which is inefficient and poses safety hazards in complex terrain. While there have been attempts to use drones to drop targets, existing technology can only carry a limited number of targets at a time and lacks a reliable directional release structure, making it difficult to meet the needs of continuous, multi-point deployment operations. Furthermore, the target structure itself is not designed to be adapted for automated drone deployment, resulting in a high failure rate during the deployment process.

[0004] Therefore, we propose a drone capable of automatically laying targets in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a drone capable of automatically laying targets, thereby solving the problem of continuous multi-point automated laying caused by the small number of targets carried, unreliable release, and unsuitable target structure in the existing drone target delivery technology mentioned in the background.

[0006] This utility model provides the following technical solution: a drone capable of automatically laying targets, including a drone body, a target assembly, and a storage shell fixed to the bottom of the drone body. The bottom of the drone body is provided with a rotary drive mechanism, and the surface of the storage shell is provided with an anti-blocking unloading mechanism. A loading port is opened on the front side of the storage shell, and a door covering the loading port is hinged to the front side of the storage shell. A fan-shaped feeding port is provided at the bottom of the storage shell and to the right of the loading port. A drive rod is rotatably connected to the bottom of the inner wall of the storage shell. Multiple equally spaced partition plates are fixed around the drive rod, and the multiple partition plates divide the internal space of the storage shell into multiple storage compartments. The space above the fan-shaped feeding port forms an unloading area.

[0007] Preferably, the target as a whole includes a central panel, with rotatable wing plates on both the left and right sides of the central panel, an extension leg fixed to the bottom of the central panel, and a counterweight fixed to the bottom of the extension leg.

[0008] Preferably, two extension blocks are fixed on both the left and right sides of the center panel surface, and a connecting rod is fixed between the upper and lower extension blocks. The wing plate is rotatably connected to the surface of the connecting rod. A torsion spring is fixed on one side of the extension block, and the torsion spring is fixedly connected to the surface of the wing plate on one side. The torsion spring causes the wing plate to have an outward expansion tendency.

[0009] Preferably, L-shaped limiting plates for preventing excessive rotation of the wing plate are fixed on both the left and right sides of the center panel surface, and the L-shaped limiting plates are located on the back of the wing plate.

[0010] Preferably, the rotary drive mechanism includes a geared motor, a bracket is fixed to the surface of the geared motor, the bracket is fixed to the bottom of the UAV body, a drive shaft is fixed to the output shaft of the geared motor, and sprockets are fixedly connected to the drive shaft and the surface of the drive rod, and the sprockets on both sides are connected by chain drive.

[0011] Preferably, the anti-blocking unloading mechanism includes an electric cylinder, which is fixed to the front surface of the storage shell and located outside the unloading area. A fan-shaped push plate is fixed to the top of the electric cylinder, and a sliding groove is provided on the surface of the storage shell in the unloading area to cooperate with the sliding of the fan-shaped push plate.

[0012] Preferably, the fan-shaped push plate is normally positioned higher than the top of the partition plate.

[0013] Preferably, an extension magnet is fixed to the right side of the inner wall of the loading port, and a groove is provided on the inner wall of the box door to accommodate the extension magnet. The box door is made of magnetic material.

[0014] This utility model has the following beneficial effects: 1. This drone, capable of automatically deploying targets, uses a storage shell combined with a compartmentalized rotating design to enable it to carry and sequentially deploy multiple targets at once. Combined with an automated compartment selection and release process, it completely changes the inefficient traditional manual method of carrying and placing targets one by one. It is especially suitable for large-scale surveying or complex terrain areas that require dense target deployment, resulting in an order-of-magnitude improvement in operational efficiency.

[0015] 2. This drone, capable of automatically deploying targets, fundamentally avoids deployment failures caused by jamming through an active anti-blocking unloading mechanism. The specially designed folding target, combined with an automatic unfolding torsion spring and mechanical limiting structure, ensures that the target quickly and consistently returns to its optimal working position after being removed from the drone. The counterweighted outriggers ensure stable target landing posture with the target facing upwards. These design features work together to make each deployment highly reliable and usable, greatly improving the data quality foundation of the entire measurement work. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: This example aims to address the challenges of automated, multi-point deployment caused by limitations in existing UAV target delivery technologies, such as limited target quantity, unreliable release, and incompatible target structures. Please refer to [link / reference]. Figures 1-7A drone capable of automatically laying targets includes a drone body 1, a target assembly 2, and a storage shell 3 fixed to the bottom of the drone body 1. The drone body 1 has a rotary drive mechanism 4 at its bottom, and the storage shell 3 has an anti-clogging unloading mechanism 5 on its surface. The storage shell 3 has a loading port 6 on its front side, and a door 7 hinged to the front side of the storage shell 3 to cover the loading port 6. A fan-shaped feeding port 8 is located at the bottom of the storage shell 3 and to the right of the loading port 6. A drive rod 9 is rotatably connected to the bottom of the inner wall of the storage shell 3. Multiple equally spaced partitions 10 are fixed around the drive rod 9, dividing the internal space of the storage shell 3 into multiple storage compartments. The space above the fan-shaped feeding port 8 forms an unloading area. An extension magnet 12 is fixed to the right side of the inner wall of the loading port 6. The inner wall of the door 7 has a groove 13 for inserting the extension magnet 12. The door 7 is made of magnetic material.

[0020] Through the above technical solution, the storage shell 3, fixed to the bottom of the UAV body 1, serves as the carrying platform for the target assembly 2. The interior of the storage shell 3 is divided into multiple independent storage compartments by the partition plate 10, achieving batch and orderly storage of targets. The rotary drive mechanism 4 drives the drive rod 9 to rotate, thereby rotating the entire compartment structure. This allows any storage compartment to be aligned with the unique fan-shaped feeding port 8 at the bottom, completing the selection of the feeding position. This structure establishes a mechanical basis for centralized storage and selective release, enabling the UAV to carry multiple targets at once and select the compartment through a simple rotation action, providing the possibility for automated and continuous operation. When the door 7 is closed, the groove 13 on the door 7 is aligned with the extended magnet 12 fixed to the inner wall of the loading port 6. This prevents the door 7 from accidentally opening during flight and causing the targets to spill out, while also ensuring the convenience of operation when loading targets.

[0021] Example 2: This example is an improvement on Example 1. The target body 2 includes a central panel 201. Rotatable wing plates 204 are provided on both the left and right sides of the central panel 201. An extension leg 202 is fixed to the bottom of the central panel 201. A counterweight block 203 is fixed to the bottom of the extension leg 202.

[0022] Through the above technical solution, the central panel 201 serves as the main body, while the extended legs 202 and counterweight 203 at the bottom provide downward pressure to ensure the target's stability during descent, prioritizing landing on the legs. The rotatable wing panels 204 on both sides can be folded down for storage to reduce volume. This target structure is optimized for UAV deployment. The combination of the counterweight 203 and the extended legs 202 significantly improves the target's stability during descent and after landing, effectively preventing tumbling and ensuring the target is laid on the ground in a preset posture, significantly improving the deployment success rate and the effectiveness of target use.

[0023] Two extension blocks 205 are fixed on the left and right sides of the surface of the center panel 201. A connecting rod 206 is fixed between the upper and lower extension blocks 205. The wing plate 204 is rotatably connected to the surface of the connecting rod 206. A torsion spring 207 is fixed on one side of the extension block 205. One side of the torsion spring 207 is fixedly connected to the surface of the wing plate 204. The torsion spring 207 makes the wing plate 204 tend to expand outward.

[0024] Through the above technical solution, the wing plate 204 is hinged to the extension block 205 of the central panel 201 via the connecting rod 206. The internal torsion spring 207 stores elastic potential energy when the wing plate 204 is constrained in the folded state. When the target is released from the constraint of the storage shell 3, the torsion spring 207 releases energy, driving the wing plate 204 to automatically and quickly unfold to the horizontal working state. This achieves a fully automatic and instantaneous transition from a compactly folded state to a fully unfolded state after the target is released, without the need for additional power or control. The structure is simple and reliable, ensuring that the target has recovered its maximum effective marking area before touching the ground, thus improving operational efficiency.

[0025] Both sides of the center panel 201 are fixed with L-shaped limiting plates 208 to prevent the wing plate 204 from rotating excessively. The L-shaped limiting plates 208 are located on the back of the wing plate 204.

[0026] Through the above technical solution, when the wing plate 204 unfolds outward under the action of the torsion spring 207, its back side will contact and abut against the surface of the L-shaped limiting plate 208, thereby preventing it from continuing to rotate, ensuring the consistency of the unfolding state of all targets, and improving the reliability and durability of the system.

[0027] Example 3: This example is an improvement on Example 1. The rotary drive mechanism 4 includes a reduction motor 401. A bracket is fixed on the surface of the reduction motor 401. The bracket is fixed to the bottom of the drone body 1. A drive shaft 402 is fixed on the output shaft of the reduction motor 401. A sprocket 403 is fixedly connected to both the drive shaft 402 and the surface of the drive rod 9. The two sprockets 403 are connected by chain drive.

[0028] Through the above technical solution, the geared motor 401 provides low-speed, high-torque rotational power. Through a transmission system consisting of the drive shaft 402, sprocket 403, and chain, the power is transmitted to the drive rod 9 inside the storage housing 3, thereby driving all the partition plates 10 to rotate synchronously. The chain drive structure is robust, reliably transmits power, and is easy to arrange in limited spaces. The geared motor 401 ensures accurate and stable rotational indexing, precisely stopping the target storage bin above the fan-shaped feeding port 8, achieving a reliable and controllable bin selection function.

[0029] Example 4: This example is an improvement on Example 1. The anti-blocking unloading mechanism 5 includes an electric cylinder 501. The electric cylinder 501 is fixed to the front surface of the storage shell 3 and located outside the unloading area. A fan-shaped push plate 502 is fixed at the top of the electric cylinder 501. The surface of the storage shell 3 located in the unloading area is provided with a sliding groove 11 that cooperates with the sliding of the fan-shaped push plate 502. The normal position of the fan-shaped push plate 502 is higher than the top position of the partition plate 10.

[0030] With the above technical solution, when the target storage bin rotates to the unloading area, i.e., above the fan-shaped feeding port 8, the electric cylinder 501 is activated, and the fan-shaped pusher plate 502 at its end moves downward along the slide groove 11 into the storage shell 3. The fan-shaped pusher plate 502 pushes the target assembly 2 located in the storage bin from the top, allowing it to overcome friction and other resistance and slide smoothly out of the fan-shaped feeding port 8. This active mechanical pushing mechanism effectively solves the problem of the target being unable to be smoothly discharged by its own weight due to jamming with the bin wall or angle issues, greatly improving the success rate and reliability of the release action and ensuring that the target can be released with every command. The normal position of the fan-shaped pusher plate 502 is set above the top of the partition plate 10. When the storage shell 3 rotates to switch bins, the partition plate 10 can pass unobstructed under the fan-shaped pusher plate 502 without collision or interference.

[0031] Working principle: The operator opens the box door 7, which is closed by the extension magnet 12, and loads multiple folded target units 2 into the storage compartments separated by the partition plate 10 inside the storage shell 3 through the loading port 6. Then, the box door 7 is closed. After the drone arrives at the work area, it enters the automatic laying process: First, the flight control system controls the drone body 1 to fly above the first target laying point and hover. Next, the rotary drive mechanism 4 is activated, and the reduction motor 401 drives the drive rod 9 and the partition plate 10 inside the storage shell 3 to rotate through the sprocket 403 and chain until the storage compartment containing the first target is precisely aligned with the unloading area above the fan-shaped feeding port 8 at the bottom. Then, the anti-blocking unloading mechanism 5 is activated, the electric cylinder 501 retracts, and pulls the fan-shaped push plate 502 down along the slide 11, pushing the target unit 2 out of the storage compartment and allowing it to fall through the fan-shaped feeding port 8. During the target's descent, its side wings 204, freed from constraints, rapidly and automatically unfold outwards under the action of torsion springs 207 until they are stopped by L-shaped limiting plates 208 and maintained in an optimal horizontal position. Simultaneously, the extended legs 202 and counterweights 203 at the bottom ensure a stable descent. After the target touches the ground, the extended legs 202 and counterweights 203 typically make initial contact with the ground. After one deployment, the fan-shaped pusher 502 returns to its initial position above the partition plate 10, and the rotary drive mechanism 4 restarts, rotating the next storage bin containing the target to the unloading position for the next deployment. This cycle continues until all targets are deployed. The entire workflow is automated through the sequential actions of the mechanical structure, from active deployment and automatic unfolding to stable landing. This achieves reliable carrying, active release, and automatic deployment of multiple specialized targets by UAVs, solving the technical problems of low efficiency and poor safety in manual deployment, as well as the limitations of UAV deployment in terms of limited carrying capacity and unreliable release.
