Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] See also Figure 1-Figure 9The present invention provides a technical solution: a logistics drone automated hub station with a helipad, comprising a shell 1, a display screen for user operation is arranged on the front of the shell 1, and the user can operate the display screen to pick up and send items according to needs, a delivery port 2 is opened on the front of the shell 1, and the user can take and place items through the delivery port 2, and also includes a helipad 3 arranged above the shell 1, the drone docks on the helipad 3 when picking up and sending items, and the helipad 3 is provided with a hatch, and the items in the hub station enter and exit through the hatch, a plurality of logistics boxes 4 are arranged in the shell 1, and the items that the user needs to pick up and send can be placed in the logistics box 4, and the drone is provided with a structure connected to the logistics box 4, which is a prior art and will not be repeated here:

[0040] A multi-axis screw moving structure is provided in the shell 1, which includes guide rails in three directions respectively of x-axis, y-axis and z-axis. A mobile platform 5 for placing the logistics box 4 is provided on the guide rails. The mobile platform 5 can move in multiple directions in the shell 1, thereby realizing the storage, retrieval and delivery of the logistics box 4. The above guide rails and screw driving structures are all existing technologies and will not be elaborated here.

[0041] A placement rack 6 for temporarily storing the logistics box 4 and a temperature-controlled counterweight mechanism 7 are provided in the shell 1. The temperature-controlled counterweight mechanism 7 can be connected to the logistics box 4 to keep it cold or warm, and can balance the center of gravity of the logistics box 4 according to its own weight.

[0042] The mobile platform 5 includes a mounting plate 51 movably arranged in the housing 1, and the mounting plate 51 can move in the housing 1 along the multi-axis screw moving structure. A slide rail 52 is fixedly arranged on the mounting plate 51, and a slider 53 is slidably arranged on the slide rail 52. An electric push rod 54 is arranged on the mounting plate 51, and the bottom end of the electric push rod 54 is arranged on the mounting plate 51, and its output end is connected to the slider 53. A placement plate 55 for placing the logistics box 4 is arranged above the slider 53, and a slide rail 2 56 is arranged at the bottom of the placement plate 55. A slider 2 57 is slidably arranged in the slide rail 2 56. Support rods 58 are rotatably arranged on the upper side walls of the sliders 1 53 and 2 57. The middle parts of the two support rods 58 are rotatably connected by a rotating shaft, and the ends of the two support rods 58 are rotatably connected to the placement plate 55 and the mounting plate 51 respectively;

[0043] When the user clicks on the display screen to place an item, the mobile platform 5 moves in the shell 1 and drives the logistics box 4 to the delivery port 2. The user opens the logistics box 4 and places the item to be delivered in it, and then clicks on the display screen again. The mobile platform 5 drives the logistics box 4 to move to the placement rack 6 for temporary storage. When the drone docks, the mobile platform 5 drives the logistics box 4 to move to the hatch under the apron 3. At this time, the electric push rod 54 starts to drive the slider 53 to move, and the two support rods 58 rotate crosswise with each other to realize the upward movement of the ends of the support rods 58, thereby driving the placement plate 55 to move upward. After the logistics box 4 moves up, the drone grabs the logistics box 4 to realize delivery. When the drone arrives at another hub station, the drone lands on the apron 3, and the logistics box 4 is again sent into the shell 1 by the mobile platform 5, waiting for the user to take it away.

[0044] The logistics box 4 includes a box body 41 and a bottom plate 42 movably arranged inside the box body 41, a support spring 43 is arranged at the bottom of the bottom plate 42, and the two ends of the support spring 43 are respectively fixedly connected to the bottom plate 42 and the bottom of the box body 41, and a plurality of trigger rods 44 arranged in a circumference are arranged in the middle section of the bottom of the bottom plate 42. A matrix pressure sensor is embedded at the bottom of the box body 41, and a connecting pipe 45 is arranged at the bottom of the box body 41 for damping rotation, and the connecting pipe 45 is communicated with the inside of the box body 41;

[0045] When an item is placed in the logistics box 4, due to the uneven weight distribution of the item itself, the weight of the item will cause the bottom plate 42 to squeeze the support spring 43, and the bottom plate 42 drives the trigger rod 44 to contact the matrix pressure sensor. The matrix pressure sensor detects the pressure distribution and then determines the center of gravity position through the smart terminal in the shell 1.

[0046] The temperature-controlled counterweight mechanism 7 includes a sliding plate 71 slidably arranged in the outer shell 1. The sliding plate 71 is arranged in the outer shell 1 through a screw drive. A bracket 72 is fixedly arranged on the sliding plate 71. Two counterweight units 8 are arranged in the bracket 72. Electric push rods 73 are arranged on both sides of the inside of the bracket 72. The output end of the electric push rod 73 is in contact with the counterweight unit 8. The movement of the sliding plate 71 can drive any one of the two counterweight units 8 to move to the bottom of the logistics box 4.

[0047] The counterweight unit 8 includes a counterweight frame 81, a counterweight block 82 is slidably arranged in the counterweight frame 81, a driving motor 83 and a screw rod 84 driven to rotate by the driving motor 83 are arranged on the counterweight frame 81, the screw rod 84 threadedly penetrates the side wall of the counterweight block 82, a sleeve 85 connected to the connecting pipe 45 is arranged on the top of the counterweight frame 81, a roller 86 is rotatably arranged on the top of the counterweight frame 81, and the roller 86 is driven by the motor. When the counterweight frame 81 is connected to the box body 41, the rotation of the roller 86 can drive the counterweight frame 81 to rotate;

[0048] After the real-time center of gravity detection of the logistics box 4, the sliding plate 71 drives the required counterweight unit 8 to move to the bottom of the logistics box 4, and then the electric push rod 2 73 drives the counterweight block 82 and the counterweight frame 81 to move up and connect with the bottom of the logistics box 4, and then the screw rod 1 84 rotates to drive the counterweight block 82 to move on the counterweight frame 81, and at the same time, the roller 86 rotates and the surface of the roller 86 contacts the bottom of the logistics box 4, thereby driving the counterweight frame 81 to rotate, so that the counterweight block 82 can be moved to any position at the bottom of the logistics box 4, and the center of gravity can be balanced by the weight of the counterweight block 82 itself.

[0049] A refrigeration unit and a heating unit are respectively arranged in the two counterweight blocks 82, and both the refrigeration unit and the heating unit can be connected to the connecting pipe 45 through the sleeve 85 above them.

An electromagnet 13 and a magnetic block 14 are respectively arranged on the fixing sleeve 10 and the positioning block 11. When the electromagnet 13 is energized, it can attract the magnetic block 14 and then drive the positioning block 11 to move toward the fixing sleeve 10. At this time, the sleeve 85 can be sleeved on the outside of the connecting tube 45, and then the electromagnet 13 is powered off. Under the action of the return spring 12, the positioning block 11 is inserted into the positioning groove 9 to realize the connection between the sleeve 85 and the connecting tube 45, and then the counterweight mechanism is installed to the bottom of the logistics box 4.

[0051] Advertising screens are arranged on both sides of the housing 1 to improve the commercial value of the hub station.

[0052] The inner wall of the box body 41 of the logistics box 4 is provided with a heat preservation layer to further enhance the cold preservation or heat preservation function of the logistics box 4 .
