Description

Technical Field

[0001] This utility model belongs to the field of cargo drone technology, and in particular relates to a hoisting mechanism for cargo drones. Background Technology

[0002] Cargo drone lifting mechanisms are an important component of modern logistics technology, offering entirely new solutions for cargo transportation through innovative design and high efficiency. These mechanisms are typically constructed from high-strength materials to ensure stability and safety during lifting and transport. The use of drones reduces the investment of manpower and resources, lowering logistics costs. These mechanisms demonstrate significant application potential in areas such as emergency supplies transportation, remote area resupply, and medical supply delivery.

[0003] Comparing with Chinese Patent No. CN220181090U, a lifting mechanism for transporting drones is disclosed. The mechanism includes a drone body with a camera mounted on its bottom surface. Landing gears are located on both sides of the drone body's bottom surface, and a support pad connects the landing gears. Lifting devices are mounted at both ends of the support pads, and a lifting ring is located at one end of each lifting device. A bolt is located on the outer side of the lifting ring near its bottom, and the lifting ring is threadedly connected to a storage basket via the bolt. Upon reaching the destination, the drone descends to a designated position, lowering the hook to a height lower than the top and bottom of the lifting ring, causing the hook to detach from the ring. A motor then rotates the hook, raising the drone body and detaching it from the storage basket. This eliminates the need for manual unloading, improving worker efficiency. Delivery can be completed even when the recipient is not present, saving labor costs and achieving partial automation.

[0004] However, the aforementioned patent requires the storage basket to be unloaded along with the cargo, which reduces the utilization rate of the storage basket. Furthermore, it is necessary to avoid drones loading goods from the top of the storage basket, which seriously affects the convenience of loading goods. Therefore, a new device needs to be designed.
