[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1.

[0017] 2. The cargo locking device for the logistics distribution drone can realize, through the set limit assembly, that when the first protective frame and the second protective frame are rotated to the left and right sides of the load-bearing platform, and the transported cargo is in a stable state on the top of the load-bearing platform under the action of the splint, the limit plate can be limited under the action of the support seat and the plug rod, thereby limiting the second rotating rod under the action of the limit plate, that is, when the cargo is fixed, the first gear and the second gear can be in a stable state, avoiding the rotation of the first gear and the second gear due to the flight of the drone body or due to external factors, thereby affecting the stability of the first protective frame, the second protective frame and the splint, thereby affecting the impact of the cargo transportation process, and when the first inclined block moves, the third inclined block can be squeezed, thereby realizing the linkage effect between the rotation of the first protective frame and the limiting process of the limit plate, thereby improving the efficiency of cargo fixation.

Moreover, more lift can be provided under the action of the first propeller and the second propeller, which means that the drone can carry heavier cargo, expand its application scope in the fields of logistics and transportation, and improve the stability and efficiency of cargo transportation.

[0019] 4. The cargo locking device for the logistics distribution drone can achieve, through the buffer mechanism, that when the drone body lands, under the action of the fourth spring, the connecting rod, the mounting seat and the buffer seat, not only can the drone body land stably, but also can play a buffering role during landing, so as to avoid damage to the drone body caused by excessive impact force of contact with the ground due to the weight of the drone body itself and the weight of the cargo. Under the elastic action of the fourth spring, a buffering effect can be provided when the drone body contacts the ground, reducing the impact force during landing, thereby protecting the structure and internal electronic equipment of the drone, and reducing the risk of rollover or crash caused by unstable landing. At the same time, under the action of the fixing bolt, the buffer seat can be easily replaced when it is worn out after long-term use, thereby further ensuring the stability of the drone body during landing.

When the drone body 1 faces strong winds or other external interferences during transportation,When providing additional lift and control force, the first propeller 35 and the first pulley 34 fixedly connected to the periphery of the third rotating rod 32 are driven to rotate by the second servo motor 31, so that the first pulley 34 drives the fourth rotating rod 39 and the second propeller 37 in the second pulley 38 to rotate through the transmission belt 36, so that the drone body 1 can be provided with additional lift and control force under the action of the first propeller 35 and the second propeller 37, and help the drone maintain a stable flight state. When the drone body 1 lands, the buffer seat 42 will contact the ground, and under the action of the buffer seat 42, the mounting seat 46, the connecting rod 45 and the pressing block 44 will be squeezed, so that the pressing block 44 slides in the fixed sleeve 41, and the fourth spring 43 is squeezed, so that the elastic action of the spring can provide a buffering effect when the drone body 1 contacts the ground, reduce the impact force during landing, thereby protecting the structure and internal electronic equipment of the drone, and at the same time can reduce the impact caused by To prevent the risk of rollover or crash caused by unstable land, when the cargo transportation is completed and the limit plate 229 needs to be released, the fixing pin 226 can be removed, so that the slide bar 227 drives the support seat 2291 and the insertion rod 228 to move downward in the cylinder 225, and the limit plate 229 can be released. Under the action of the first gear 2191 and the second gear 2194, the first protection frame 218 and the second protection frame 21997 are opened, and the first spring 2198 and the second spring 21997 are closed. 21996 is reset, so that the clamping plate 21995 releases the fixation of the goods, and the goods can be taken out, and the first inclined block 21991 releases the squeezing of the third inclined block 221, so that the third spring 223 is reset, so that the cylinder 225 and the slide bar 227 can move downward, and under the action of the fixing pin 226, the cylinder 225 and the slide bar 227 are fixed again, ensuring the stability of the support seat 2291 and the insertion rod 228, and the subsequent transportation work can be resumed.
