[0002] With the rapid development of the logistics industry, the transportation of goods by unmanned automatic driving unmanned vehicles can effectively save labor costs and improve delivery efficiency.

[0003] Generally speaking, the "last mile" in logistics transportation refers to the distance from the transfer station to the customer's hand. The current common delivery method mainly transports goods in a loop through the conveyor belt. In special cases such as transporting specific valuable goods, unmanned vehicles are needed to transport goods to a specific location and wait for the customer to take them away. Due to the uncertainty of the customer's pickup time, the unmanned vehicle often needs to wait for a long time, resulting in low utilization of the delivery equipment and affecting the delivery efficiency. SUMMARY

[0004] The purpose of the present application is to provide a logistics delivery collaborative distribution device to solve the problem of uncertain pickup time, long waiting time for unmanned vehicles, and low utilization of delivery equipment in the prior art. Not only can the unmanned vehicle deliver the delivery shelf, but also during the waiting time for the customer, the driving assembly can drive a pair of second connecting rods and a pair of first connecting rods to move away from each other, i.e. a pair of guide rods are used to stabilize a pair of second connecting rods, a second gear is used to rotate to drive one of the guide rods to move, a pair of second connecting rods are used to move in opposite directions to make the first connecting rod and the clamping seat separate, so that a single unmanned vehicle can repeatedly transport multiple different delivery shelves without interruption, achieving the effect of improving the utilization of delivery equipment.

[0005] Moreover, the delivery shelf separated from the unmanned vehicle can be used to wait for the customer of the corresponding order at a specific location. The second servo cylinder is used to lower the support plate, which is used to stabilize and support the first connecting rod to fix the delivery shelf. After the customer arrives, the customer can selectively control the moving assembly or directly use the moving assembly to drive a pair of third connecting rods to unload the goods. The second servo motor is used to rotate the screw to move the limiting block in the opposite direction, so that a pair of third connecting rods move away from each other to unload the goods. Or use the moving assembly to drive a pair of third connecting rods to continue to move closer to fix the goods, move the delivery shelf to assist the customer to transport the goods, so as to realize the collaborative cooperation of the delivery shelf and the unmanned vehicle, improve the existing delivery mode, and create an intelligent logistics distribution platform that can speed up the transportation efficiency of goods and improve the customer's pickup experience.

The adjusting seat 6 is provided with a transmission member, and the two ends of the transmission member are connected with the suction cup 5 and the adjusting ring 7, respectively. When the suction cup 5 abuts against the goods, the suction cup 5 moves towards the adjusting seat 6, and the adjusting ring 7 abuts against the outer side of the suction cup 5.

[0055] The two adjusting seats 6 arranged opposite to each other are moved closer to each other by the third connecting rod 3, so that the two suction cups 5 move in opposite directions.

[0059] Specifically, when the suction cup 5 contacts the goods, the suction cup 5 extrudes the transmission rod 8 and the spring 9 at the same time, and the transmission rod 8 drives the two first toothed plates 10 to move towards the sliding groove. Through the meshing of the first toothed plate 10 and the first gear 11, the second toothed plate 12 is driven to move away from the sliding groove, so that the adjusting ring 7 moves towards the suction cup 5 and abuts against the outer ring side of the suction cup 5, thereby improving the structural support strength of the suction cup 5 and ensuring the clamping stability.
