Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles (UAVs), in particular to an object delivery device for UAVs. Background Art

[0002] Drone delivery systems are widely used in emergency rescue, logistics distribution, agricultural spraying, and environmental monitoring. In emergency rescue, they can quickly deliver medicine and relief supplies. In logistics distribution, drones enable efficient package delivery, especially in remote areas. Agricultural spraying uses drones to improve the precision and efficiency of crop management. Regarding market trends, drone delivery systems are becoming increasingly popular as technological advances and costs decrease.

[0003] After searching, an existing patent (Announcement No.: CN216443797U) discloses a drone delivery device, which relates to the field of air transport equipment technology and includes: a support member, a loading plate, and a drive device. The support member is used to be detachably mounted on the drone, and the drive device is fixedly mounted on the support member. The loading plate is an arc-shaped plate, and the cylindrical surface where the inner wall of the loading plate is located is a first cylindrical surface. The central axis of the first cylindrical surface is a first axis. The drive device can drive the loading plate to rotate around the first axis. In the loading state, the first axis is in a horizontal state, and the inner side of the loading plate is used to carry objects. The drone delivery device provided by the utility model uses a loading plate to carry objects. When an object needs to be dropped, the drive device drives the loading plate to rotate, and the object falls under the action of its own gravity, thereby achieving the effect of dropping the object in the air. Compared with the clamps in the prior art, the loading plate has a large load capacity and a stable structure.

[0004] However, in the actual use of the above solution, the items are placed directly on the support. However, at high altitudes, the airflow is chaotic and the drone will be affected by the airflow and shake, which may cause the items to fall off the support or collide with the device itself, causing the items to fall or be damaged.

[0005] To this end, the utility model provides a drone object delivery device. Utility Model Content
