Description

Technical Field

[0001] This utility model relates to the field of delivery control equipment, and in particular to a drone delivery device. Background Technology

[0002] Drone technology is now widely used, enabling observation of areas inaccessible to humans and the delivery of various supplies, thus providing convenience to people's lives. With the continuous upgrading of drone technology and its increasingly widespread applications, such as disaster relief, urban firefighting, and battlefield delivery, the scenarios for using drones to deliver goods are becoming increasingly diverse.

[0003] Currently, most delivery devices used in practice involve suspending the delivery object on a rope at the drone's mounting point. Due to the flexible swing of the rope, it has a significant impact on the drone's takeoff and flight attitude, making it difficult to control the stability of the delivery, resulting in inaccurate delivery to the designated location and the delivery object easily falling off. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a drone delivery device that uses a pusher block to push a T-shaped hook to release and drop the item, making control more convenient. It can also adjust the coordinates in both the X and Y horizontal and vertical directions, making the delivery position adjustable, more precise, and allowing for high-precision delivery with easy item release.

The XY coordinate component is used to change the coordinates of the item being placed in the X and Y directions. When the item being placed moves to the target area, the push block is driven by the power component to slide in the T-slot, which can push the T-hook out of the T-slot. The item will then separate from the device and fall, thus realizing the placement of the item.
