Description

Technical Field

[0001] This utility model relates to the field of drone application technology, specifically a leaflet airdrop device for drones. Background Technology

[0002] With the popularization of drone technology, its application in advertising, event promotion, and other fields is becoming increasingly widespread. Traditional advertising methods, such as manual distribution and fixed-point placement, suffer from low efficiency, limited coverage, and high labor costs. Using drones for airdropping flyers can efficiently and accurately cover large areas, making it particularly suitable for large-scale events, scenic spots, and specific communities.

[0003] However, existing drone airdrop devices typically have the following problems:

[0004] Complex structure: Many devices use electromagnets or complex mechanical transmission structures, resulting in high cost and weight, which affects the drone's endurance.

[0005] Unreliable delivery: Due to wind, the flyers may not be able to detach smoothly from the device, resulting in "stuck flyers" or delivery failure.

[0006] Poor delivery accuracy: It is impossible to control the quantity of each delivery, and all of them may be scattered at once, making it impossible to achieve precise delivery by area or time period.

[0007] Therefore, this utility model provides a leaflet airdrop device for drones to solve the above problems. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] This utility model provides a flyer airdrop device for drones, aiming to solve the problem in the background art where flyers may not be able to detach smoothly from the device under the influence of wind, resulting in "flyer jamming" or delivery failure.

[0012] As a preferred technical solution of this application, the feeding mechanism includes an annular moving plate, with a plurality of feeding plates equidistantly arranged on one side of the annular moving plate. Both ends of the inner wall of the annular moving plate are rotatably connected to support shafts, and one end of each of the two support shafts is drivenly connected to a synchronous pulley. The two synchronous pulleys are drivenly connected by the same synchronous belt, and the inner wall of one of the synchronous pulleys is drivenly connected to the output end of a motor. The motor is fixedly connected to one end of the storage box.

[0013] As a preferred technical solution of this application, the wind resistance mechanism includes a flexible connecting rope, and multiple counterweights are linearly and equidistantly arranged on the outside of the flexible connecting rope. The counterweights are spherical in shape, and the flexible connecting rope is located at the center of gravity projection point of the drone body.

[0014] As a preferred technical solution of this application, a bearing seat is fixedly connected to the bottom of the connecting plate, a bearing is provided inside the bearing seat, the bearing seat is rotatably connected to the rotating shaft through the bearing, and the bottom end of the rotating shaft is connected to the top of the flexible connecting rope.

[0017] (III) Beneficial Effects

[0018] 1. This flyer-dropping device for drones, through a feeding mechanism driven by a motor and synchronous belt, can intermittently and quantitatively dispense flyers from the outlet. Combined with a pressing mechanism that can be pressed down, it always keeps the bottom of the flyer stack in contact with the feeding plate, ensuring that only one or a few flyers are dispensed at a time. This achieves precise delivery by area and time period, fundamentally solving the problems of "flyer jamming" or all flyers being scattered at once caused by static electricity or adhesion in traditional devices.

[0019] 2. This leaflet airdrop device for drones abandons complex electromagnets or pneumatic structures, mainly adopting mechanical transmission and simple electric components. The transparent window on the side of the storage box makes it easy to observe the remaining leaflets in real time, and the hinged cover makes loading and maintenance extremely convenient. This design not only reduces manufacturing costs, but also improves the reliability and service life of the device, making it very suitable for large-scale applications. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1-4A flyer airdrop device for drones includes a drone body 1, a storage box 2 at the bottom of the drone body 1, a pressing mechanism 3 inside the storage box 2, a material-dispensing mechanism 4 inside the storage box 2, two connecting frames 5 fixedly connected to the bottom of the storage box 2, the two connecting frames 5 being connected by the same connecting plate 6, a wind resistance mechanism 7 at the bottom of the connecting plate 6, a discharge port 8 on one side of the storage box 2, a guide lip at the discharge port 8, and the guide lip tilting outward and downward, the outward and downward tilting guide lip at the discharge port 8 provides a smooth transition track for the dispensing flyers, guiding the flyers to leave the device at the optimal angle and fall naturally by their own weight, further reducing the risk of being caught or blocked at the discharge port 8, a cover plate 9 hinged to one end of the storage box 2, by setting the cover plate 9 to facilitate placing the paper in the storage box 2, and transparent windows 10 on both sides of the storage box 2, through which the paper inside the storage box 2 can be observed.

[0028] Please see Figure 2 and Figure 3 The feeding mechanism 4 includes an annular moving plate 401. Multiple feeding plates 402 are equidistantly arranged on one side of the annular moving plate 401. Both ends of the inner wall of the annular moving plate 401 are rotatably connected to support shafts 403. One end of each of the two support shafts 403 is drivenly connected to a synchronous pulley 404. The two synchronous pulleys 404 are drivenly connected by the same synchronous belt 405. The inner wall of one of the synchronous pulleys 404 is drivenly connected to the output end of a motor 406. The motor 406 is fixedly connected to one end of the storage box 2.

[0029] Please see Figure 2 and Figure 4 The wind resistance mechanism 7 includes a flexible connecting rope 701, with multiple counterweights 702 arranged linearly and equidistantly on the outside of the flexible connecting rope 701. The counterweights 702 are spherical in shape. The flexible connecting rope 701 is located at the center of gravity projection point of the UAV body 1. The wind resistance mechanism 7 based on the flexible connecting rope 701 and the counterweights 702 is set at the bottom of the device. This mechanism is located below the center of gravity projection point of the UAV body. During flight or hovering, when encountering crosswinds, the counterweights 702 counteract the wind force through the swing of the flexible connecting rope 701 and the rotation of the pivot 13, and can quickly restore stability with the help of the friction of the damping ring, significantly reducing the attitude fluctuation of the UAV itself, thereby ensuring flight safety and the accuracy of the delivery path.

[0030] A bearing seat 12 is fixedly connected to the bottom of the connecting plate 6. A bearing 11 is installed inside the bearing seat 12. The bearing seat 12 is rotatably connected to the rotating shaft 13 through the bearing 11. The bottom end of the rotating shaft 13 is connected to the top of the flexible connecting rope 701. The wind resistance mechanism 7 is connected through the bearing seat 12 and the rotating shaft 13, so that the counterweight mechanism can rotate freely in the horizontal plane with the change of wind direction, avoiding the risk of the connecting rope getting tangled in the drone landing gear.

[0031] The top of the connecting plate 6 is provided with a mounting groove 14. The connecting plate 6 is detachably installed with the first damping ring 15 through the mounting groove 14. The outer wall of the rotating shaft 13 is fixedly connected with a second damping ring 16. The outer wall of the second damping ring 16 is rotatably connected with the inner wall of the first damping ring 15. Through the cooperation of the first damping ring 15 and the second damping ring 16, a certain damping is applied to the rotation of the rotating shaft 13 to prevent it from oscillating at high frequency under the action of wind, thus ensuring the smoothness and stability of the wind resistance effect.

[0032] Please see Figure 1 and Figure 2 The pressing mechanism 3 includes a pressing plate 301. The outer wall of the pressing plate 301 is movably connected to the inner wall of the storage box 2. Two electric telescopic rods 302 are provided on the top of the pressing plate 301, and both electric telescopic rods 302 are fixedly connected to the top of the storage box 2. By setting the pressing mechanism 3, the promotional leaflet can be pressed together to ensure the stability of the promotional leaflet and avoid the situation of the leaflet getting stuck.

[0033] The operator opens the cover 9 at the front of the storage box 2 and places a neatly stacked stack of leaflets into the inner cavity of the storage box 2. After closing the cover 9, the electric telescopic rod 302 of the pressing mechanism 3 extends, pushing the pressure plate 301 downward to apply appropriate pressure to the stack of leaflets, so that its bottom is tightly against the inner bottom wall of the storage box 2.

[0034] Flight and Preparation Phase: The UAV, equipped with this device, flies towards the target airspace. During this process, the wind-resistant mechanism 7 located below the connecting plate 6 begins to function. When the UAV is impacted by crosswinds, the wind force attempts to deflect the fuselage. At this time, the flexible connecting rope 701 and the counterweight 702 connected by the pivot 13 maintain their original state due to inertia, thereby generating a resisting torque opposite to the direction of the wind force, helping to stabilize the fuselage. Simultaneously, the pivot 13 rotates within the bearing 11 and is subjected to the frictional force between the first damping ring 15 and the second damping ring 16, causing the movement of the wind-resistant mechanism 7 to be damped, preventing continuous oscillations and quickly restoring stability.

[0035] Deployment Phase: The drone arrives at the designated deployment point and hovers stably. The control system activates motor 406 of the material-feeding mechanism 4. The output shaft of motor 406 drives a synchronous pulley 404 to rotate, transmitting power to another synchronous pulley 404 via synchronous belt 405, thus causing the two support shafts 403 to rotate synchronously. The support shafts 403 drive the annular moving plate 401 and its evenly distributed material-feeding plates 402 in a circular motion. When the material-feeding plates 402 move to the bottom of the leaflet stack, they will push the bottom one or more leaflets, causing them to slide out of the discharge port 8. At the outlet, the leaflets are guided by an outward and downward inclined guide lip, smoothly detaching from the device and falling towards the target area under the influence of gravity. Motor 406 can operate in an intermittent mode to achieve quantitative and interval deployment, ensuring a wider and more uniform coverage of the leaflets.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
