Description

Technical Field

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

[0002] The delivery device for logistics drones is a core component mounted on the drone itself, used to carry, lift, and deliver goods. Its core function is to work with drones to achieve aerial transportation and precise delivery of goods, overcome bottlenecks such as ground traffic congestion and terrain limitations, and improve logistics and distribution efficiency. It is especially suitable for transportation needs in remote areas and emergency supplies.

[0003] When drones deliver supplies, they often need to land on the ground to complete the delivery. However, in complex terrain scenarios, drones often have difficulty landing safely. In such cases, it is necessary to use cables to suspend the supplies for delivery. However, during high-altitude transportation, the suspended supplies are prone to swaying. If the swaying is severe, it will seriously interfere with the drone's flight attitude, causing attitude confusion. In severe cases, it may even cause the drone to lose control and crash. Moreover, existing conveying devices generally have defects such as uneven cable winding that is easy to get tangled, inaccurate cargo positioning, and unstable fixing structure that can easily cause cargo to fall. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a conveying device for logistics drones.

[0005] The technical solution adopted by this utility model is: a conveying device for logistics drones, including a drone body, a shell fixedly installed on the lower surface of the drone body, and a first chamber and a second chamber opened inside the shell; A servo motor is fixedly installed in the first chamber inside the housing. A first gear is fixedly installed at the working end of the servo motor. A winding reel that matches the first gear is fixedly installed in the second chamber inside the housing. One shaft end of the winding reel is located in the first chamber and a second gear that meshes with the first gear is fixedly installed therein. A rope is wound on the outer surface of the winding reel.

[0006] Preferably, an electric threaded rod and a sliding rod are fixedly installed in symmetrical grooves inside the housing. The outer surface of the electric threaded rod is threaded with a sliding block that matches the inside of the groove. The other end of the sliding block is slidably connected to the outer surface of the sliding rod.

[0007] Preferably, a collar is fixedly installed at the middle of the outer surface of the slide block, and the inner surface of the collar is rounded.

[0008] Preferably, a guide ring is fixedly installed on the lower surface of the housing, and one end of the rope is fixedly installed with a box via a collar and the guide ring.

[0009] Preferably, two landing legs are fixedly installed on the lower surface of the drone body, and baffles are fixedly installed on the outer surfaces of the two landing legs.

[0010] Preferably, each of the two partition blocks is provided with three electric push rods inside, and the working end of the three electric push rods is provided with a support plate.

[0011] Preferably, the four upper corners of the box are magnetically set, and the two bottom corners of the two partition blocks are magnetically set.

[0012] The above-described solution of this utility model has at least the following beneficial effects: In this invention, a servo motor drives the meshing of gear one and gear two to drive the winding wheel, achieving stable winding and unwinding of the rope. The transmission structure is precise and the power output is stable. At the same time, an electric threaded rod drives the sliding block to slide back and forth along the sliding rod. With the help of the collar, the rope is evenly wound on the winding wheel, avoiding knots and stacking problems that occur during the rope winding process. In addition, the guide ring limits the lower end of the rope, ensuring that the rope is always in the middle position during winding and unwinding, effectively reducing the swaying amplitude of the box during the lifting and lowering process.

[0013] In this invention, an electric push rod pushes the pallet to firmly lift the box from the bottom. Combined with the limiting space formed by the partition block, a double fixing guarantee is formed, which solves the problem of the box being easy to loosen and fall off during the movement of the drone, further improving the safety of cargo transportation and better protecting the items inside the box from damage.

[0016] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0017] like Figures 1 to 6 As shown, an embodiment of this utility model provides a conveying device for a logistics drone, including a drone body 1, a housing 3 fixedly installed on the lower surface of the drone body 1, and a first chamber and a second chamber opened inside the housing 3. A servo motor 4 is fixedly installed in the first chamber inside the housing 3. A first gear 5 is fixedly installed at the working end of the servo motor 4. A winding wheel 6 that matches it is fixedly installed in the second chamber inside the housing 3. One shaft end of the winding wheel 6 is located in the first chamber and a second gear 7 that meshes with the first gear 5 is fixedly installed. A rope 8 is wound on the outer surface of the winding wheel 6.

[0018] The servo motor 4 is connected to the built-in power supply of the drone body 1 to work, thereby driving the first gear 5 to rotate, which in turn drives the second gear 7, which is meshed with the first gear 5, to rotate the winding wheel 6 and wind up the rope 8 wrapped on the surface of the winding wheel 6. The rope 8 is made of nylon and is evenly wound around the outer surface of the take-up reel 6. The position of the take-up and release rope 8 is located in the middle section of the lower surface of the drone body 1.

[0019] like Figure 3 , Figure 4 and Figure 6 As shown, an electric threaded rod 9 and a slide rod 10 are fixedly installed in symmetrical grooves inside the housing 3. A sliding block 11 matching the inside of the groove is threaded onto the outer surface of the electric threaded rod 9. The other end of the sliding block 11 is slidably connected to the outer surface of the slide rod 10. A collar 12 is fixedly installed in the middle of the outer surface of the sliding block 11. The inner surface of the collar 12 is rounded. A guide ring 17 is fixedly installed on the lower surface of the housing 3. One end of the rope 8 is fixedly installed to the housing 16 through the collar 12 and the guide ring 17.

[0020] One end of the rope 8 passes through the collar 12. When the rope 8 is wound up or down, the electric threaded rod 9 drives the slide block 11 to slide back and forth along the slide rod 10, thereby driving the collar 12 to slide back and forth, so that the collar 12 and the rope 8 can be evenly wound in the winding wheel 6. The guide ring 17 ensures that the lower end of the rope 8 is always in the middle position during winding, which can reduce the large swaying of the box 16 when the rope 8 is wound up.

[0021] like Figure 5 and Figure 6As shown, two landing legs 2 are fixedly installed on the lower surface of the drone body 1. A baffle block 13 is fixedly installed on the outer surface of each of the two landing legs 2. Three electric push rods 14 are provided inside each of the two baffle blocks 13. A support plate 15 is provided at the working end of each of the three electric push rods 14.

[0022] The inner surfaces of the two side partitions 13 are glued with sponge, which cushions the box 16 and reduces the shaking of the box 16, thus protecting the contents. The space formed by the box 16 and the two side partitions 13 of the adhesive sponge is matched. The box 16 is folded up by the rope 8 so that the box 16 fits in the space formed by the two partitions 13. Then the electric push rod 14 connected to the drone body 1 is activated. The electric push rod 14 pushes the tray 15 to lift the box 16 from the bottom and prevent it from falling during movement.

[0023] like Figure 6 As shown, the four upper corners of the box 16 are magnetically set, and the two bottom corners of the two partition blocks 13 are magnetically set.

[0024] The four magnetic corners of the housing 16 are aligned with the two bottom magnetic corners of the partition block 13, which allows the housing 16 to be corrected when it moves to the bottom of the two partition blocks 13.

[0025] Working principle: The drone body 1 serves as the supporting base. Inside the fixed shell 3 below it, the servo motor 4 in the first chamber is powered on and drives the first gear 5 at the output end to rotate. The second gear 7, which meshes with the first gear 5, drives the winding wheel 6 in the second chamber to rotate, realizing the winding and unwinding operation of the nylon rope 8 wrapped around its outer side. The position of the rope 8 during winding and unwinding is always at the lower center of the drone body 1. During the winding and unwinding process, the electric threaded rod 9 in the slide groove inside the shell 3 rotates, driving the threaded sliding block 11 to slide back and forth along the slide rod 10. The collar in the middle of the sliding block 11 moves synchronously, so that the rope 8 is evenly wound on the winding wheel 6. At the same time, the guide ring at the bottom of the shell 3... 17. Ensure that the lower end of the rope 8 is always in the middle position to effectively reduce the shaking of the box 16. One end of the rope 8 passes through the collar 12 and the guide ring 17 in sequence and is fixed to the box 16. When the box 16 is retracted by the rope 8, the magnetic structure at the four corners of its upper end is precisely attracted to the magnetic structure at the bottom two corners of the two outer partition blocks 13 of the two landing legs 2, realizing the automatic alignment of the box 16. The box 16 fits into the space formed by the two partition blocks 13. Then, the three electric push rods 14 inside the partition block 13 are powered on and start, pushing the tray 15 at its working end to lift it upward, and steadily lift the box 16 from the bottom, preventing the box 16 from falling during the movement of the drone, and completing the safe transportation of materials.
