[0001] The present invention relates to the technical field of logistics transport vehicles, and in particular to an unmanned logistics transport vehicle. Background Art

[0002] Unmanned logistics transport vehicles are devices that transport goods by driving a transport vehicle with a drone. However, with the development of science and technology, people's requirements for unmanned logistics transport vehicles are getting higher and higher, resulting in traditional unmanned logistics transport vehicles can no longer meet people's needs.

[0003] At present, when the existing unmanned logistics transport vehicles are in use, the goods to be transported are first placed in the transport vehicle by humans, and then the transportation route information is input into the unmanned logistics transport vehicle. The unmanned logistics transport vehicle then transports the goods to the designated location and returns to the transportation site after completion. In this process, first, the cargo transport vehicle needs to stop working when picking up the goods, which affects the transportation efficiency of the cargo transport vehicle; second, different goods require storage boxes of different sizes, and the existing storage boxes are of constant size and quantity and cannot be adaptively changed; third, when transporting goods, the goods inside the storage box are prone to shaking, causing damage to the goods. For this reason, we propose an unmanned logistics transport vehicle. Summary of the invention

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Reference Figure 1-3 As shown, an unmanned logistics transport vehicle includes a driving base 1 and a plurality of storage boxes 2 stacked on top of the driving base 1. A docking seat 3 is installed at the top center of the driving base 1, wherein:

[0032] The outer side of the docking seat 3 is connected to multiple groups of grippers 5 through hinges, and a self-locking motor 4 is installed inside the docking seat 3. The self-locking motor 4 is connected to the top of the gripper 5 through a traction rope 6 wrapped around its output shaft, and a spring is provided between the bottom of the gripper 5 and the outer wall of the docking seat 3.

[0033] Reference Figure 2 As shown, a movable groove is provided at the edge of the driving base 1 close to the docking seat 3 , and a connecting seat corresponding to the docking seat 3 is welded at the bottom of the storage box 2 located at the bottom.

[0034] Reference Figure 3 A pressure sensor is installed on the top of the docking seat 3, a main battery is installed inside the driving base 1, and the input ends of the self-locking motor 4 and the pressure sensor are electrically connected to the output end of the main battery through wires.

[0035] Reference Figure 3 A hook is installed on the top of the gripper 5, and the distance between the hook and the top of the docking seat 3 is equal to the height of the connecting seat.

[0036] Reference Figure 2 , Figure 4 and Figure 5 As shown, telescopic rods 7 are welded at the four corners of the top of the driving base 1, and the telescopic rods 7 correspond to the guide grooves opened at the four corners of the storage box 2, and a docking column 8 is installed inside the guide groove. The upper and lower ends of the docking column 8 are respectively provided with a threaded column and a threaded groove, and a connecting plate 9 is installed inside the docking column 8.

[0037] Reference Figure 6 As shown, reserved grooves are opened at equal intervals on the outside of the connecting plate 9, and an electromagnetic plate 10 is installed on the inner surface of the reserved groove. The electromagnetic plate 10 is connected to a movable pin 11 located inside the reserved groove through a spring, and a slot corresponding to the movable pin 11 is opened on the inner wall of the guide groove.

[0038] Reference Figure 6 An electromagnetic coil is installed inside the electromagnetic plate 10, and a secondary battery and a wireless transceiver are installed inside the docking column 8. The input ends of the wireless transceiver and the electromagnetic coil are electrically connected to the output end of the secondary battery through a wire.

[0039] Reference Figure 7 As shown, an air bag 12 is bonded to the bottom of the storage box 2, and the air bag 12 is connected to an air pump installed inside the storage box 2 through an air pipe.

[0040] Reference Figure 7 The bottom of the airbag 12 is bonded with a metal mesh, and the outside of the metal mesh is bonded with a rubber ring.

[0041] Before use, the staff will place the storage box 2 with the goods stored on the driving base 1, and make the storage box 2 with the connecting seat at the bottom. When placing it, make the connecting seat at the bottom of the lowest storage box 2 correspond to the docking seat 3 at the center of the driving base 1, and squeeze the pressure sensor at the top of the docking seat 3. The pressure sensor detects the weight of the storage box 2 at this time, and then controls the self-locking motor 4 to rotate forward to release the wound traction rope 6. Since a spring is provided between the bottom of the gripper 5 and the outside of the docking seat 3, when the traction rope 6 is released, the bottom of the gripper 5 rotates along the hinge between the gripper 5 and the docking seat 3 under the action of the spring, so that the hook at the top of the gripper 5 is buckled on the top of the connecting seat, thereby limiting the position between the connecting seat and the docking seat 3. At the same time, the telescopic rod 7 is controlled to extend and inserted into the guide grooves at the four corners of the storage box 2, and into the bolt groove at the bottom of the docking column 8, so that the storage box 2 and the driving base 1 are connected. Therefore, the storage box 2 can be freely replaced as needed, thereby separating the storage time of the goods from the transportation process of the goods, thereby improving the transportation efficiency and avoiding too much time for changing the goods.

[0042] After storage is completed, the air pump is controlled to inflate the airbag 12, so that the airbag 12 is inflated and expanded, and the metal mesh bonded to the outside of the airbag 12 is squeezed toward the direction of the goods. During the squeezing process, the metal mesh is tightly attached to the outside of the goods under the pressure of the airbag 12. Therefore, during transportation, the goods are confined in a certain space and will not shake violently.

[0043] When taking or placing goods, information is sent to wireless transceivers at different positions to control the electromagnetic plate 10 at the corresponding position to be powered off. Then, the movable pin 11 located outside the electromagnetic plate 10 is popped outward under the action of the spring and inserted into the corresponding pin groove on the inner wall of the guide groove, thereby fixing the docking column 8 with the storage box 2. Then, the telescopic rod 7 is extended to push the docking column 8 inside the guide groove upward, so that the docking column 8 is raised. Since the storage box 2 at the specified position is fixedly connected to the docking column 8, the storage box 2 at this position rises upward with the docking column 8, thereby leaking out the storage box 2 below the storage box 2. Then, the goods can be stored or taken out as needed.

[0044] When the number of storage boxes 2 needs to be increased, the lowest storage box 2 is first removed, and then the new docking column 8 is installed under the original docking column 8, so that the new docking column 8 is fixedly connected to the original docking column 8, and the internal electromagnetic plate 10 of the docking column 8 is controlled to be energized to attract the movable pin 11 so that the movable pin 11 retracts into the reserved groove, and then the new storage box 2 is placed below the original storage box 2. After completion, the previously removed storage box 2 is installed to the bottom of all storage boxes 2, and the electromagnetic plate 10 at the bottom is controlled to be deenergized so that the movable pin 11 is inserted into the slot, and the position of the lowest storage box 2 and the lowest movable pin 11 is fixed, and the installation of the storage box 2 is completed.
