Description

Technical Field

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

[0002] Drones can be used to airdrop supplies to areas inaccessible by ground transportation. To achieve this, an external delivery device is typically installed on the drone to carry the supplies. When the drone reaches the designated delivery point, the supplies detach from the device, completing the delivery. However, due to factors such as suspension swaying during flight, it is not always possible to guarantee a stable and accurate delivery of supplies to the target point. Utility Model Content

[0003] The technical problem this invention aims to solve is how to ensure that materials are delivered smoothly and accurately to the target delivery point.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A drone delivery device includes a drone, a guiding mechanism, a launching and retrieving mechanism, and a delivery mechanism. The drone is equipped with the guiding mechanism and the launching and retrieving mechanism. The output end of the guiding mechanism is connected to the output end of the launching and retrieving mechanism, and the delivery mechanism is located at the output end of the launching and retrieving mechanism.

[0006] The guiding mechanism includes a guide telescopic tube, the fixed end of which is fixed to the UAV, and the telescopic end is fixed to the output end of the extension and retraction mechanism;

[0007] The deployment mechanism includes a deployment fixing plate, a servo motor, a mounting base, a rocker arm, a connecting rod, a bushing, a spring, a preload shaft, and a guide plate. The deployment fixing plate is fixed to the output end of the deployment and take-up mechanism. The servo motor, the mounting base, and the bushing are all fixed to the bottom of the deployment fixing plate. The output end of the servo motor is connected to the rocker arm. A sliding connecting rod is provided on the mounting base. One end of the connecting rod is hinged to the rocker arm. A spring is installed inside the bushing. One end of the preload shaft extends into the bushing and is low-pressure spring, while the other end is located outside the bushing. Guide plates are also fixed at both ends of the deployment fixing plate.

[0008] By fixing the guide telescopic tube to the deployment and take-up mechanism, the deployment mechanism will not shake when the output end of the deployment and take-up mechanism is lowered and when the UAV is flying, thus ensuring that the load will not shake. The preload shaft is pressed against the upper surface of the load by the spring to position the load vertically and limit the load's vertical jump during UAV flight. At the same time, the connecting rod structure at the top of the load is locked in the guide groove of the guide plate on both sides to limit the load's left and right swaying during UAV flight, thus avoiding the deployment deviation caused by throwing or hanging flight swaying, and ensuring that the materials are deployed smoothly and accurately to the target deployment point.

[0009] Preferably, the mounting base consists of two sets of parallel fixing blocks with a gap between them, and the fixing blocks are provided with mounting holes that allow the connecting rod to slide.

[0010] Preferably, the spring is always in a compressed state.

[0011] Preferably, two sets of bushings are provided on the casting fixing plate.

[0012] Preferably, the bottoms of the two sets of bushings are connected by a connecting plate, and the connecting plate has a through hole.

[0013] Preferably, a guide groove is provided on the opposite side of the guide plate.

[0014] Preferably, the take-up and take-down mechanism includes a take-up and take-down fixing plate, a take-up and take-down motor, a rubber reel, a cable, and a take-up and take-down fixing seat. The take-up and take-down fixing plate is fixed to the UAV, the take-up and take-down motor is fixed to the bottom of the take-up and take-down fixing plate, the output end of the take-up and take-down motor is connected to the rubber reel, one end of the cable is wound around the rubber reel, and the other end is connected to the take-up and take-down fixing seat. The telescopic end of the guide telescopic tube and the fixing plate are both connected to the fixing seat.

[0015] Preferably, the receiver / discharger is a worm gear reducer motor.

[0016] Preferably, the retractable fixing seat is Z-shaped.

[0017] Preferably, it also includes a camera mechanism, which is fixed on the outermost tube of the guide telescopic tube.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By fixing the guide telescopic tube to the deployment and take-up mechanism, the deployment mechanism will not shake when the output end of the deployment and take-up mechanism is lowered and when the UAV is flying, thus ensuring that the load will not shake. The preload shaft is pressed against the upper surface of the load by the spring to position the load vertically and limit the load's vertical jump during UAV flight. At the same time, the connecting rod structure at the top of the load is locked in the guide groove of the guide plate on both sides to limit the load's left and right swaying during UAV flight, thus avoiding the deployment deviation caused by throwing or hanging flight swaying, and ensuring that the materials are deployed smoothly and accurately to the target deployment point.

[0028] See Figure 1 and Figure 2 A drone delivery device includes a drone 1, a guide mechanism 2, a take-up and release mechanism 3, a delivery mechanism 4, and a camera mechanism 5. The drone 1 is equipped with the guide mechanism 2 and the take-up and release mechanism 3. The output end of the guide mechanism 2 is connected to the output end of the take-up and release mechanism 3. The delivery mechanism 4 is located at the output end of the take-up and release mechanism 3. The delivery mechanism 4 is used to suspend the delivered load 6.

[0029] See Figure 3 The guiding mechanism 2 includes a fixed tube 21 and a guide telescopic tube 22. The fixed tube 21 is fixed to the drone 1, and the camera mechanism 5 is fixed to the outer wall of the fixed tube 21. The fixed end of the guide telescopic tube 22 is fixed inside the fixed tube 21, and the bottom telescopic end of the guide telescopic tube 22 is fixedly connected to the output end of the retraction mechanism 3. Furthermore, the guide telescopic tube 22 is composed of multiple square tubes connected together, and the bottom of the innermost square tube is fixedly connected to the output end of the retraction mechanism 3.

[0030] See Figure 4The take-up and release mechanism 3 includes a take-up and release fixing plate 31, a take-up and release motor 32, a rubber reel 33, a cable 34, and a take-up and release fixing base 35. The take-up and release fixing plate 31 is fixed to the UAV 1, and the take-up and release motor 32 is fixed to the bottom of the take-up and release fixing plate 31. The output end of the take-up and release motor 32 is connected to the rubber reel 33. In this embodiment, the take-up and release motor 32 is a worm gear reducer motor. The worm gear reducer motor has a high reduction ratio and self-locking capability, which can improve the load mounting capacity and safety. One end of the cable 34 is wound around the rubber reel 33, and the other end is connected to the take-up and release fixing base 35. The telescopic end of the guide telescopic tube 22 is fixedly connected to the fixing base 35.

[0031] Furthermore, cable 34 is made of lightweight polymer material to ensure load-bearing capacity and reduce its own weight.

[0032] Furthermore, the retractable fixing base 35 is Z-shaped, the telescopic end of the guide telescopic tube 22 is fixed to the bottom horizontal end of the retractable fixing base 35, and the delivery mechanism 4 is fixed to the top horizontal end of the retractable fixing base 35.

[0033] See Figure 2 By fixing the guide telescopic tube 22 to the launch and retraction fixed seat 35, the launch and retraction fixed seat 35 will not shake when it is lowered with the cable 34 and when the drone 1 is flying, thus ensuring that the load 6 will not shake.

[0034] See Figure 5 The launching mechanism 4 includes a launching fixing plate 41, a servo motor 42, a mounting base 43, a swing arm 44, a connecting rod 45, a bushing 46, a spring 47, a preload shaft 48, and a guide plate 49. The launching fixing plate 41 is fixed below the top horizontal end of the launching fixing base 35. The servo motor 42, the mounting base 43, and the bushing 46 are all fixed to the bottom of the launching fixing plate 41. The output end of the servo motor 42 is hinged to the swing arm 44. The mounting base 43 is provided with a sliding connecting rod 45, which is used to hang the load 6. One end of the connecting rod 45 is hinged to the swing arm 44. The bushing 46 is provided with a spring 47 that is always in a compressed state. One end of the preload shaft 48 extends into the bushing 46 and is low-pressure spring 47, while the other end is provided outside the bushing 46. The launching fixing plate 41 is also fixed with guide plates 49 at both ends. The guide plates 49 are provided with guide grooves 491 on opposite sides.

[0035] The mounting base 43 consists of two sets of parallel fixing blocks with a gap between them. Both sets of fixing blocks are provided with mounting holes that allow the connecting rod 45 to slide.

[0036] In this embodiment, two sets of symmetrical bushings 46 are provided on the delivery fixing plate, and each set of bushings 46 is provided with a spring 47 and a preload shaft 48.

[0037] Furthermore, the bottoms of the two sets of bushings 46 are connected by a connecting plate 40, which ensures the stability of the bushings 46; the connecting plate 40 is provided with a through hole 401 to facilitate the passage of the connecting rod structure at the top of the load 6.

[0038] Specifically, the top of the load 6 is slidably connected to the connecting rod 45 between the two sets of fixed blocks via a connecting rod structure, causing the load 6 to hang on the connecting rod 45. This makes the load 6 prone to swaying when hanging on the connecting rod 45. Therefore, in this embodiment, a spring 47 that is always in a compressed state is set to press the preload shaft 48 against the upper surface of the load 6, thereby positioning the load 6 vertically and limiting the vertical jump of the load 6 during the flight of the UAV 1. At the same time, the two sides of the connecting rod structure at the top of the load 6 are also vertically slidably locked in the guide groove 491 of the guide plate 49, limiting the left and right swaying of the load 6 during the flight of the UAV 1, thereby avoiding the delivery deviation caused by throwing or hanging flight swaying, and ensuring that the materials are delivered smoothly and accurately to the target delivery point.

[0039] In summary, in this embodiment, by fixing the guide telescopic tube 22 to the retraction and deployment fixing seat 35, the deployment fixing seat 35 will not shake when it is lowered with the cable 34 and when the UAV 1 is flying, thus ensuring that the load 6 will not shake. The spring 47 presses the preload shaft 48 against the upper surface of the load 6 to position the load 6 vertically and limit the vertical jump of the load 6 when the UAV 1 is flying. At the same time, the connecting rod structure at the top of the load 6 is engaged in the guide groove 491 of the guide plate 49 on both sides, limiting the left and right sway of the load 6 when the UAV 1 is flying, thus avoiding the deployment deviation caused by throwing or hanging flight sway, and ensuring that the materials are deployed smoothly and accurately to the target deployment point.
