[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1) This intelligent airdrop locking device for drone logistics operates by using a servo motor that drives a rack and pinion ring to rotate via a series of transmissions. The rotating ring then drives a connecting block to rotate, causing a connecting rod to deflect around the connecting block. This deflects a locking block around a pin, which in turn pushes the locking block together to engage the connecting pin, thus locking the cargo. When the delivery area is reached, the reverse servo motor drives the rack and pinion ring to rotate in reverse, which in turn drives the rotating ring to rotate. This causes the connecting rod to deflect towards the inner wall of the rotating ring, disengaging the locking block from the connecting pin and releasing the lock, thus completing the airdrop operation. This device improves the locking effect on the cargo, prevents safety hazards, and enhances the locking quality and safety of the device.
[0015] 2) This intelligent airdrop locking device for drone logistics uses a servo motor to drive the first helical gear to rotate, which in turn drives the second helical gear meshing with the first helical gear to rotate, which in turn drives the connecting rod and the rotating wheel to rotate, which in turn drives the belt and the driven wheel to rotate, which in turn drives the rack ring to rotate, which in turn drives the rotating ring to rotate and lock the goods with the locking block. This device can provide power to ensure the locking state of the fixed mechanism for the goods, and can also flexibly move the position of the locking block to improve the delivery quality and enhance the practicality of the device.
